技术领域
本申请涉及清洁设备技术领域,具体而言,涉及一种毛发切割组件、一种清洁设备和一种切割控制方法。
背景技术
目前,吸尘器等清洁设备被广泛使用并且逐步进入各家各户。吸尘器清洁头的主要工作部件为旋转滚刷,滚刷接触地面将地面灰尘拍打、刷起。而头发等细长的纤维状垃圾很容易缠绕在滚刷上,影响滚刷的清洁效果且难以清理。
相关技术的清洁设备中,通过刀片切断缠绕在滚刷上的纤维状垃圾,解除缠绕并吸走。然而清洁设备在进行清洁工作时,随滚刷一起旋转的垃圾会加剧刀片损伤,影响刀片对纤维状垃圾的切割效果。
发明内容
为了解决或改善上述技术问题至少之一,本申请的一个目的在于提供一种毛发切割组件。
本申请的另一个目的在于提供一种具有上述毛发切割组件的清洁设备。
本申请的另一个目的在于提供一种切割控制方法。
为了实现上述目的,本申请第一方面的技术方案提供了一种毛发切割组件,包括:壳体;滚刷,与壳体连接,滚刷包括旋转轴,滚刷能够沿旋转轴相对壳体转动;定刀片,与壳体连接,定刀片与壳体相对固定;动刀片,与壳体连接,动刀片能够相对定刀片移动,动刀片与定刀片相抵,且定刀片与动刀片相对于滚刷的周向方向相邻;其中,在滚刷的横截面上,旋转轴至定刀片与动刀片相抵的平面的第六距离小于滚刷的最大半径尺寸,且第六距离非零。
本申请中旋转轴至定刀片与动刀片相抵的平面的第六距离小于滚刷的最大半径尺寸,且第六距离非零,由于第六距离非零,故而切割面并不是完全沿滚刷的径向延伸的,避免刀片完全指向轴心,可减少垂直打击在刀片上的垃圾数量,保护刀片。此外,通过限制第六距离小于滚刷的最大半径尺寸,可使得沿刀尖延伸会直接指到滚刷上,从而在滚刷上缠绕有毛发时,更便于接触到切割面进行切割,即可剪到沿滚刷切向甩起的毛发,在保证起到有效剪切到头发的基础上,减小了刀片受到的垃圾打击力。
本申请另一方面的技术方案提供了一种毛发切割组件,包括:壳体;滚刷,与壳体连接,滚刷能够沿转动轴线相对壳体转动;定刀片,与壳体连接,定刀片与壳体相对固定;动刀片,与壳体连接,动刀片能够相对定刀片移动,定刀片与动刀片相对于滚刷的周向方向相邻,转动轴线所在的平面在随着滚刷沿第一旋转方向转动时,平面先后经过定刀片与动刀片。
根据本申请提供的毛发切割组件的实施例,垃圾随滚刷沿其旋转方向一起转动时,先接触不运动的定刀片,在一定程度上能够对动刀片进行保护,降低垃圾对动刀片的损伤,确保动刀片的有效使用时间,有利于提高动刀片对纤维状垃圾的切割效果。
具体而言,毛发切割组件包括壳体、滚刷、定刀片和动刀片。其中,滚刷、定刀片以及动刀片均与壳体连接,壳体主要起到安装载体的作用。在一些技术方案中,可选地,滚刷能够沿转动轴线相对壳体转动。可选地,滚刷包括辊子和设于辊子周向侧壁的多排刷毛。滚刷的转动轴线可以理解为辊子的转动轴线。滚刷的转动实质为辊子带动刷毛转动。清洁设备进行清洁工作时,滚刷接触地面,滚刷的刷毛将地面灰尘进行拍打并且将垃圾 刷起、卷入至壳体内。
在一些技术方案中,可选地,定刀片与壳体相对固定。动刀片能够相对定刀片移动。可选地,动刀片与定刀片相抵。可选地,动刀片具有第一工位与第二工位。动刀片能够由第一工位向第二工位移动或由第二工位向第一工位移动。可选地,动刀片沿滚刷的转动轴线移动进行剪切。动刀片在第一工位与第二工位之间相对定刀片移动,动刀片与定刀片的相对运动形成有效剪切动作,对纤维状垃圾(比如缠绕在滚刷上的毛发)进行切割。可选地,壳体包括安装壳体、第一支撑壳体和第二支撑壳体。滚刷与安装壳体连接,且滚刷能够沿转动轴线相对安装壳体转动。定刀片与第一支撑壳体连接,且动刀片与第二支撑壳体连接。第一支撑壳体与安装壳体连接,且第二支撑壳体与安装壳体连接。第一支撑壳体与安装壳体之间的连接方式为粘接或焊接等;第二支撑壳体与安装壳体之间的连接方式为粘接或焊接等。
在一些技术方案中,可选地,定刀片与动刀片相对于滚刷的周向方向相邻。可选地,定刀片与动刀片位于平面的同一侧。滚刷的转动轴线所在的平面在随着滚刷沿第一旋转方向转动时,此平面先后经过定刀片与动刀片。垃圾随滚刷沿其旋转方向一起转动时,先接触不运动的定刀片,在一定程度上能够对动刀片进行保护,降低垃圾对动刀片的损伤,确保动刀片的有效使用时间,有利于提高动刀片对纤维状垃圾的切割效果。
本申请另一方面的技术方案提供了一种毛发切割组件,包括:驱动件,驱动件的一侧设有偏心柱;动刀片,通过偏心柱与驱动件传动连接;垫块,设于动刀片上,垫块上设有受动部,偏心柱伸入受动部或偏心柱伸入动刀片的第一限位孔和受动部。
毛发切割组件,主要包括驱动件、偏心柱以及动刀片,驱动件起到提供主动力的作用,在驱动件对偏心柱进行驱动的作用下会驱使动刀片进行往复移动,从而实现对毛发的切割。驱动件与动刀片传动连接,具体为,驱动件会带动设于一侧的偏心柱转动,动刀片上设有第一限位孔,通过将偏心柱伸入到第一限位孔内,在转动时即可使得动刀片沿第二方向运动。
在一些实施例中,偏心柱伸入受动部使得动刀片沿第二方向运动,而 对于动刀片上是否设有第一限位孔,本申请不作限定。
需要强调的,在动刀片上设置有垫块,通过在垫块上设置受动部,偏心柱在带动动刀片移动的同时,会在受动部的作用下带动垫块也随之移动,可以理解,垫块与动刀片是一同移动的,在动刀片上设置垫块,可增大偏心柱与动刀片之间的接触面积,从而将作用于动刀片上的扭矩予以缩减,即原有力对全部作用于动刀片上,动刀片越厚,力的传递效率越高,磨损越小,但随之而来的是动刀片单体的厚度的增加,不利于加工,而本申请是通过在动刀片上设置垫块,将垫块与动刀片相连,利用垫块变向的增大的动刀片与偏心柱的接触面积,从而实现磨损的降低。
需要补充的是,本申请中提到偏心柱伸入第一限位孔仅为相对位置关系,与偏心柱直接接触的为垫块。在一些实施例中,垫块和第一限位孔可同时与偏心柱直接接触。
其中,动刀片是沿第二方向延伸的,第一限位孔则是沿垂直于第二方向的第一方向延伸,例,动刀片横向移动,第一限位孔竖向设置,从而使得偏心轮在转动时,偏心柱会与第一限位孔配合,从而使得动刀片沿第二方向移动。
可以理解,由于采用分体的垫块,垫块的材质可以选择较轻的耐磨材质,从而相比于直接对刀片做厚处理的方案,本申请的整个质量有所降低,同时耐磨程度也明显增强,极大的提高产品的竞争力。
此外,如果出现磨损,由于垫块设置在动刀片远离定刀片的一侧,垫块位于动刀片的端部,会首先发生损坏,此时可进行单独更换,降低维修成本。
可以理解,定刀片的位置是固定,动刀片通过偏心柱与驱动件间接连接,在偏心柱和第一限位孔的共同作用下,即可使得动刀片会相对于定刀片发生移动,从而实现对毛发的切割效果。
需要补充的是,定刀片和动刀片之间是相邻设置的,以便于在动刀片移动时,在刃部的作用下实现切割。
在一些技术方案中,可选地,驱动件可选择普通电机或减速电机。
本申请另一方面的技术方案提供了一种毛发切割组件,包括:驱动件; 主动件,与驱动件的驱动轴连接;传动轮,与主动件相啮合,且传动轮的轴线与驱动轴的轴线不平行;偏心柱,与传动轮连接;动刀片,设于偏心柱上;其中,传动轮转动,通过动刀片和偏心柱的配合以使动刀片做往复运动。
本申请提供的毛发切割组件,主要包括驱动件、主动件和传动轮,驱动件起到提供主动力的作用,主动件和传动轮作为减速器,最终将驱动件的转动转换为对动刀片的横向驱动。具体地,主动件直接套设在驱动轴上,驱动轴转动会带动主动件一同转动,在主动件和传动轮的啮合作用下,会使得传动轮也发生转动,由于传动轮的轴线相对于驱动轴的轴线是不平行的,在动刀片设置在偏心柱的情况下,传动轮的轴线与动刀片之间也是不平行的,在此基础上,由于采用主动件的结构,可使得主动件的轴线与动刀片的延伸方向大体上是平行的,进而会对驱动件的位置予以限制,使其从大体垂直于动刀片的延伸平面的方向错开,利用大体上平行的位置,使得整个驱动组件的厚度方向的尺寸,即传动轮的轴线方向上的尺寸有所减小。
本申请第二方面的技术方案提供了一种清洁设备,包括:上述任一实施例中的毛发切割组件;第一驱动件,与毛发切割组件的滚刷连接,第一驱动件用于驱动滚刷沿其轴线转动;第二驱动件,与毛发切割组件的动刀片连接,第二驱动件用于驱动动刀片相对毛发切割组件的定刀片移动;控制器,与第一驱动件连接,控制器与第二驱动件连接。
其中,清洁设备包括但不限于吸尘器、洗地机、扫地机器人等可对地面上灰尘、毛发进行收集清洁的设备。
控制器可在清洁设备刚启动进行清洁工作时,控制动刀片相对定刀片运动,运动一定时间后自动停止。
控制器可在清洁设备进行清洁工作时,动刀片一直相对定刀片静止。
控制器可在动刀片相对定刀片运动时,清洁设备未进行清洁工作。
控制器可在动刀片相对定刀片运动时,清洁设备滚刷旋转,旋转方向与清洁设备进行清洁工作时滚刷的旋转方向相反。
在一些技术方案中,可选地,还包括:检测装置,与所述控制器连接, 所述检测装置用于检测粘连在或缠绕在所述滚刷上的垃圾数量;其中,所述控制器用于确定所述清洁设备的滚刷处于工作状态,并且根据所述检测装置确定所述滚刷上的垃圾大于第一阈值时,控制所述动刀片处于运动状态;或所述控制器用于控制所述动刀片处于运动状态,根据所述检测装置确定所述滚刷上的垃圾小于第二阈值时,控制所述动刀片停止运动,所述第二阈值不大于所述第一阈值。
在一些技术方案中,可选地,检测装置与所述毛发切割组件的壳体连接,所述检测装置为光学识别摄像头;或所述检测装置与所述第一驱动件连接,所述检测装置用于检测所述第一驱动件的电流值。
在一些技术方案中,可选地,还包括:第一储存容器,与所述毛发切割组件的壳体连接,所述第一储存容器用于储存清洁液体,所述第一储存容器与所述毛发切割组件的腔体连通;第二储存容器,与所述壳体连接,所述第二储存容器用于储存垃圾与污水,所述第二储存容器与所述毛发切割组件的腔体连通。

在本申请实施例中,先获取到运行模式,根据不同的运行模式可确定出对应的转动参数和移动参数,包括但不限于转动速度、转动方向、转动频率,以及移动距离和移动速度等。随后分别根据转动参数和移动参数控制滚刷和动刀片的移动,从而实现不同模式的运行。
在一些技术方案中,可选地,还包括:根据检测装置检测粘连在或缠绕在所述滚刷上的垃圾数量;确定所述滚刷处于工作状态,并且根据所述检测装置确定所述滚刷上的垃圾数量大于第一阈值时,控制所述动刀片处于运动状态;或控制所述动刀片处于运动状态,根据所述检测装置确定所述滚刷上的垃圾数量小于第二阈值时,控制所述动刀片停止运动;其中,所述第二阈值不大于所述第一阈值。

如图1所示,根据本申请提出的一个实施例的毛发切割组件100,包括 壳体110、滚刷120、定刀片131和动刀片132。其中,滚刷120、定刀片131以及动刀片132均与壳体110连接,壳体110主要起到安装载体的作用。在一些实施例中,滚刷120能够沿其旋转轴相对壳体110转动。可选地,如图2所示,滚刷120包括辊体121和设于辊体周向侧壁的多排刷毛122。滚刷120的旋转轴可以理解为辊体121的旋转轴。滚刷120的转动实质为辊体带动刷毛122转动。清洁设备进行清洁工作时,滚刷120接触地面,滚刷120的刷毛122将地面灰尘进行拍打并且将垃圾刷起、卷入至壳体110内。
在一些实施例中,定刀片131与壳体110相对固定。动刀片132能够相对定刀片131移动。动刀片132与定刀片131相抵。可选地,动刀片132具有第一工位与第二工位。动刀片132能够由第一工位向第二工位移动或由第二工位向第一工位移动,以使动刀片132靠近或远离滚刷120。动刀片132在第一工位与第二工位之间相对定刀片131移动,动刀片132与定刀片131的相对运动形成有效剪切动作,对纤维状垃圾(比如缠绕在滚刷120上的毛发)进行切割。可选地,壳体110包括安装壳体111、第一支撑壳体112和第二支撑壳体113。滚刷120与安装壳体111连接,且滚刷120能够沿其旋转轴相对安装壳体111转动。定刀片131与第一支撑壳体112连接,且动刀片132与第二支撑壳体113连接。第一支撑壳体112与安装壳体111连接,且第二支撑壳体113与安装壳体111连接。第一支撑壳体112与安装壳体111之间的连接方式为粘接或焊接等;第二支撑壳体113与安装壳体111之间的连接方式为粘接或焊接等。
需要强调的是,本申请中旋转轴至定刀片131与动刀片132相抵的平面的第六距离L1小于滚刷120的最大半径尺寸,且第六距离非零,可使得切割面会斜向伸入滚刷120,由于第六距离非零,故而切割面并不是完全沿滚刷120的径向延伸的,避免刀片完全指向轴心,可减少垂直打击在刀片上的垃圾数量,保护刀片。此外,通过限制第六距离小于滚刷120的最大半径尺寸,可使得沿刀尖延伸会直接指到滚刷上,从而在滚刷120上缠绕有毛发时,更便于接触到切割面进行切割,即可剪到沿滚刷切向甩起的毛发,在保证起到有效剪切到头发的基础上,减小了刀片受到的垃圾打击 力。
在一些实施例中,在壳体110上设置梳齿140,可对一些大颗粒垃圾进行过滤和遮挡,具体地,梳齿140和两种刀片的相对位置为,梳齿140位于最外侧,定刀片131位于中间,动刀片132位于最内侧,在滚刷120旋转时,会依次经过梳齿140、定刀片131和动刀片132,梳齿140和定刀片131可对移动的动刀片132起到保护效果。
在一些实施例中,可选地,梳齿140的位置可设置在图1中右上角处。
其中,梳齿140和定刀片131的相对位置会错开25°,即梳齿140朝向滚刷120的一端与定刀片131朝向滚刷120的一端,与滚刷120的旋转轴所呈的圆周角不大于25°,以提供合适的空间,方便对灰尘、毛发等物体进行收集。
在一些实施例中,通过对最大半径尺寸和第一距离的具体比值进行限制,限制二者比值大于或等于1.1,可进一步使得在滚刷120上缠绕有毛发时,更便于接触到切割面进行切割,保证毛发切割组件的长久使用。
如图1所示,根据本申请提出的一个实施例的毛发切割组件100,包括壳体110、滚刷120、定刀片131和动刀片132。其中,滚刷120、定刀片131以及动刀片132均与壳体110连接,壳体110主要起到安装载体的作用。在一些实施例中,滚刷120能够沿其旋转轴相对壳体110转动。可选地,滚刷120包括辊体和设于辊体周向侧壁的多排刷毛122。滚刷120的旋转轴可以理解为辊体的旋转轴。滚刷120的转动实质为辊体带动刷毛122转动。清洁设备进行清洁工作时,滚刷120接触地面,滚刷120的刷毛122将地面灰尘进行拍打并且将垃圾刷起、卷入至壳体110内。
其中,如图2和图4所示,对于滚刷120而言,具体包括辊体121、刷毛122和板片123,辊体121作为刷毛122和板片123的基座,辊体121与壳体110转动连接,通过将刷毛122螺旋设置在辊体121的外侧壁上,以便于对灰尘、垃圾、毛发等进行收集,在此基础上,还可在辊体121上设置与刷毛122平行的板片123,从而可对毛发进行顶起,防止直接缠绕在辊体121上,导致无法正常清扫。
其中,对于刀片、板片123和刷毛122的位置而言,定刀片131和动 刀片132的端部距离旋转轴的轴线之间为第二距离L2,会大于板片123的最大半径尺寸且小于刷毛122的最大半径尺寸,即第二距离大于第二最大半径尺寸且小于第一最大半径尺寸,对于第二距离而言,应处于第一最大半径尺寸和第二最大半径尺寸之间。
需要补充的是,第二最大半径尺寸小于第一最大半径尺寸,即刷毛122的径向长度更长,板片123则略短于刷毛122的径向长度。
通过将刷毛和板片在辊体的周向方向上相邻设置,以便于在板片的作用下对毛发等容易缠绕在辊体上的结构进行支撑,便于动刀片的切割。
旋转轴所在的平面在随着滚刷沿第一旋转方向转动时,所述平面先后经过刷毛和板片。在一些实施例中,若滚刷大部分零部件不动,每排刷毛绕滚刷的旋转轴沿第二旋转方向旋转最多40度,会接触到一个板片(假设第一旋转方向为滚刷进行正常清洁工作时的旋转方向,第二旋转方向为其方向)。
特别是,通过对第二最大半径尺寸、第一最大半径尺寸与第二距离进行大小限定,限定第二距离位于第二最大半径尺寸和第一最大半径尺寸之间,从而可使得刀片可有效的对刷毛上的毛发进行切割,同时并不会作用到板片上,降低板片与刀片之间直接接触所造成的破坏。
在一个实施例中,在每个刷毛122的一侧会设置有一个板片123,从而实现对应的毛发支撑效果。
在另一个实施例中,在每个刷毛122的两侧分别设置一个板片123,无论滚刷120如何旋转,均可对毛发起到支撑效果。
滚刷旋转一周时,每根刷毛旋转所包络的区域,至少与一个板片旋转所包络的区域,存在至少部分重叠。
需要补充的是,对于刷毛122和板片123而言,限制旋转轴所在平面会先经过刷毛122,再经过板片123,即通过刷毛122可将毛发带动起来,在转动的过程中,板片123会对毛发起到一定的支撑作用,从而一方面便于动刀片132和定刀片131对毛发进行切割,另一方面也便于将毛发收集至尘盒中。
对于定刀片和动刀片的设置位置而言,需要限定其与滚刷倾斜设置, 且在滚刷转动过程中,动刀片是顺着滚刷转动方向设置的,即在滚刷的横截面上,动刀片延伸方向所在直线与滚刷的横截面相交处,在滚刷的转动方向上的切线,与动刀片延伸方向之间的夹角为锐角。具体地,如图1所示,定刀片和动刀片设于滚刷的右上方,滚刷在图1中的旋转方向为逆时针,动刀片的尾端所对应的切线方向是朝向左上方,这个方向与动刀片的延伸方向之间呈锐角,从而可减少在径向方向上与刷毛的重叠尺寸,可有效减少杂物直接打到定刀片上的可能,提高动刀片的使用寿命。
如图1所示,根据本申请提出的一个实施例的毛发切割组件100,包括壳体110、滚刷120、定刀片131和动刀片132。其中,滚刷120、定刀片131以及动刀片132均与壳体110连接,壳体110主要起到安装载体的作用。在一些实施例中,滚刷120能够沿其旋转轴相对壳体110转动。可选地,滚刷120包括辊体和设于辊体周向侧壁的多排刷毛122。滚刷120的旋转轴可以理解为辊体的旋转轴。滚刷120的转动实质为辊体带动刷毛122转动。清洁设备进行清洁工作时,滚刷120接触地面,滚刷120的刷毛122将地面灰尘进行拍打并且将垃圾刷起、卷入至壳体110内。
在一些实施例中,如图3所示,定刀片131上设有第一刀齿1312,动刀片132上设有第二刀齿1322,第一刀齿1312和第二刀齿1322分别设置在定刀片131和动刀片132朝向滚刷120的一侧,例如第一刀齿1312的下侧设置定刀片131,第二刀齿1322的下侧设置动刀片132,从而在驱动动刀片132相对于定刀片131往复运动时,即可实现对毛发的切断。需要强调的是,本方案中,第一刀齿1312和第二刀齿1322均是间隔设置的,同时每个第一刀齿1312均与一个第二刀齿1322对应设置,动刀片132在往复运动的过程中,第二刀齿1322的运动的行程会处于对应的两个第一刀齿1312之间,以最短的行程实现对毛发的切割。
此外,如图10所示,本方案中第一刀齿1312和第二刀齿1322的位置并不均匀设置,而是采用不规则错位的对应设置关系,即第一刀齿1312的左侧和第二刀齿1322的左侧之间存在一定的距离差H,该距离差H可在0.1mm至2mm之间浮动,对于第一刀齿1312和第二刀齿1322而言,采用不均匀的分布,可提高对毛发的切割效果。
可以理解,第一刀齿1312和第二刀齿1322均位于第一壳体110和第二壳体110的外部,从而实现对外部毛发的切割。
其中,定刀片131上的第一刀齿1312可以根据定刀片131的位置选择单侧开刃,或者双侧开刃。
在一个具体的实施例中,在滚刷120的横截面上,第一刀齿1312朝向滚刷120的一端与旋转轴之间的距离为第四距离,动刀片132处于第一工位时,第二刀齿1322朝向滚刷120的一端与旋转轴之间的距离为第五距离,动刀片132处于第二工位时,第二刀齿1322朝向滚刷120的一端与旋转轴之间的距离为第三距离,第五距离大于第四距离,且第三距离大于第四距离。
第五距离大于第四距离,即处于第一工位的动刀片132的齿尖侧与滚刷120的旋转轴之间的距离大于定刀片131的齿尖侧与滚刷120的旋转轴之间的距离。第三距离大于第四距离,即处于第二工位的动刀片132的齿尖侧与滚刷120的旋转轴之间的距离大于定刀片131的齿尖侧与滚刷120的旋转轴之间的距离。总而言之,无论动刀片132处于第一工位还是处于第二工位,其齿尖侧与滚刷120的旋转轴之间的距离均大于定刀片131的齿尖侧与旋转轴之间的距离。粘连在滚刷120上或缠绕在滚刷120上的垃圾优先接触不运动的定刀片131,有利于对动刀片132进行保护,降低垃圾对刀片的损伤。定刀片131的齿尖侧比动刀片132的齿尖侧更突出(更靠近滚刷120),避免人体直接触碰到动刀片132的刀尖造成伤害。
在一些实施例中,第五距离大于第三距离,第三距离与第四距离的差值不小于0.1mm。
第五距离大于第三距离,即处于第一工位的动刀片132的齿尖侧与滚刷120的旋转轴之间的距离大于处于第二工位的动刀片132的齿尖侧与滚刷120的旋转轴之间的距离。动刀片132由第一工位向第二工位移动时,动刀片132逐渐靠近滚刷120;动刀片132由第二工位向第一工位移动时,动刀片132逐渐远离滚刷120。通过第三距离与第四距离的差值不小于0.1mm,一方面,确保第三距离大于第四距离,粘连在滚刷120上或缠绕在滚刷120上的垃圾优先接触不运动的定刀片131,对动刀片132进行保护; 另一方面,控制第三距离与第四距离的差值不会过大,保证动刀片132对纤维状垃圾的切割效果。
在一些实施例中,第四距离不大于滚刷120的最大半径尺寸,第四距离与最大半径尺寸的差值不大于5mm;第三距离不小于最大半径尺寸,第三距离与最大半径尺寸的差值不大于5mm。
滚刷120的最大半径尺寸为滚刷120的最外边缘与轴线之间的距离。可选地,辊体的半径加上刷毛122的长度,再减去刷毛122嵌入辊体的长度,等于滚刷120的最大半径尺寸。第四距离不大于滚刷120的最大半径尺寸,即定刀片131的齿尖侧与滚刷120的旋转轴之间的距离小于或等于滚刷120的最大半径尺寸。当定刀片131的齿尖侧与滚刷120的旋转轴之间的距离小于滚刷120的最大半径尺寸时,表示定刀片131的齿尖侧能够伸入滚刷120中,以提高定刀片131对粘连在滚刷120上或缠绕在滚刷120上的垃圾的切割效果。在一些实施例中,第四距离与滚刷120的最大半径尺寸的差值不大于5mm,定刀片131的齿尖侧伸入滚刷120的伸入长度小于或等于5mm,一方面,能够确保定刀片131本身的切割效果;另一方面,避免定刀片131的齿尖侧伸入长度过大,影响刷毛122的伸展以及明显增大滚刷120的转动阻力。
在一些实施例中,第三距离不小于滚刷120的最大半径尺寸,即处于第二工位的动刀片132的齿尖侧与滚刷120的旋转轴之间的距离大于或等于滚刷120的最大半径尺寸。可以理解为,动刀片132的齿尖侧不伸入至滚刷120中。在一些实施例中,第三距离与滚刷120的最大半径尺寸的差值不大于5mm,动刀片132的齿尖侧虽然不伸入滚刷120中,但其齿尖侧与滚刷120的最外边缘足够接近,确保动刀片132的切割效果。
其中,第四距离不小于滚刷120的最大半径尺寸,第四距离与最大半径尺寸的差值不大于5mm。
第四距离不小于滚刷120的最大半径尺寸,即定刀片131的齿尖侧与滚刷120的旋转轴之间的距离大于或等于滚刷120的最大半径尺寸。可以理解为,定刀片131的齿尖侧不伸入至滚刷120中,避免定刀片131的齿尖侧伸入滚刷120后,影响刷毛122的伸展以及明显增大滚刷120的转动 阻力。在一些实施例中,第四距离与滚刷120的最大半径尺寸的差值不大于5mm,定刀片131的齿尖侧虽然不伸入滚刷120中,但其齿尖侧与滚刷120的最外边缘足够接近,确保定刀片131的切割效果。
在另一个实施例中,壳体110具有腔体114,至少部分滚刷120设于腔体114内,至少部分定刀片131设于腔体114内,动刀片132处于第二工位时,至少部分动刀片132设于腔体114内。
在该实施例中,滚刷120中至少存在一部分设于腔体114内,定刀片131中至少存在一部分设于腔体114内,处于第二工位状态下的动刀片132中至少存在一部分设于腔体114内。清洁设备进行清洁工作时,滚刷120接触地面,滚刷120的刷毛122将地面灰尘进行拍打并且将垃圾刷起、卷入至壳体110的腔体114内,垃圾随滚刷120沿其旋转方向一起转动时,动刀片132与定刀片131的相对运动形成有效剪切动作,对纤维状垃圾(比如缠绕在滚刷120上的毛发)进行切割,之后这部分垃圾被吸入并收集在储存容器或储存腔内。
如图5和图6所示,本申请的一个实施例提供的清洁设备200,包括上述任一实施例中的毛发切割组件100、第一驱动件211和第二驱动件212。具体地,第一驱动件211与毛发切割组件100的滚刷120连接,第一驱动件211用于驱动滚刷120沿其轴线转动。第一驱动件211驱动滚刷120沿第一旋转方向或第二旋转方向转动。可选地,滚刷120沿第一旋转方向转动时为滚刷120的正转;滚刷120沿第二旋转方向转动时为滚刷120的反转。清洁设备200进行清洁工作时,滚刷120接触地面,滚刷120的刷毛122将地面灰尘进行拍打并且将垃圾刷起、卷入至壳体110的腔体114内。
在一些实施例中,第二驱动件212与毛发切割组件100的动刀片132连接,第二驱动件212用于驱动动刀片132相对毛发切割组件100的定刀片131移动。动刀片132与定刀片131的相对运动形成有效剪切动作,对纤维状垃圾(比如缠绕在滚刷120上的毛发)进行切割,以提高清洁效果。

在一些实施例中,如图7和图8所示,清洁设备200还包括检测装置230。具体地,检测装置230与控制器220连接。检测装置230用于检测粘连在或缠绕在滚刷120上的垃圾数量。控制器220能够根据检测装置230提供的关于垃圾数量的信息,控制动刀片132的运动状态。具体的控制方法为:确定滚刷120处于工作状态,并且根据检测装置230确定滚刷120上的垃圾大于第一阈值时,控制动刀片132处于运动状态;或控制动刀片132处于运动状态,根据检测装置230确定滚刷120上的垃圾小于第二阈值时,控制动刀片132停止运动。第二阈值不大于第一阈值。可以理解为,第一阈值可以与第二阈值相同,也可以不同。当第一阈值与第二阈值不同时,第二阈值小于第一阈值。
在一些实施例中,检测装置230与毛发切割组件100的壳体110连接,检测装置230为光学识别摄像头;或检测装置230与第一驱动件211连接,检测装置230用于检测第一驱动件211的电流值。检测装置230具有两种方案,第一种是光学识别摄像头,通过光学识别摄像头直观判断粘连在滚刷120上或缠绕在滚刷120上的垃圾数量的多少;第二种是电子装置,用于检测第一驱动件211的电流值,当电流值大于阈值时表示粘连在滚刷120上或缠绕在滚刷120上的垃圾数量较多,当电流值不大于阈值时表示粘连在滚刷120上或缠绕在滚刷120上的垃圾数量较少。
值得说明的是,清洁设备200包括但不限于吸尘器、洗地机、扫地机器人等可对地面上灰尘、毛发进行收集清洁的设备。

其中,上述两个实施例的区别在于,独立开关241是具有独立的开关实体结构,而遥控开关242则是集成在虚拟屏幕中的一个功能按键,或是一段编写好的程序。
在另一个实施例中,如图9所示,清洁设备200还包括第一储存容器251和第二储存容器252。具体地,第一储存容器251与毛发切割组件100的壳体110连接。第一储存容器251用于储存清洁液体。第一储存容器251与毛发切割组件100的腔体114连通。在一些实施例中,第二储存容器252与壳体110连接。第二储存容器252用于储存垃圾与污水。第二储存容器252与毛发切割组件100的腔体114连通。第一储存容器251中储存的清洁液体可以涂覆在滚刷120的表面,以提高清洁效果。滚刷120卷起的垃圾、经过切割后的垃圾以及处理后的污水均流入第二储存容器252内,用户可以在完成清洁工作后将第二储存容器252中储存的垃圾与污水倒出。
在一个实施例中,可直接在清洁设备200上设有独立开关/遥控开关,由用户通过开关操作决定动刀片132是否相对定刀片131运动,反馈至控制器220处,最终根据开关的指令对动刀片132的运动进行控制。

在本实施例中,先获取到运行模式,根据不同的运行模式可确定出对应的转动参数和移动参数,包括但不限于转动速度、转动方向、转动频率,以及移动距离和移动速度等。随后分别根据转动参数和移动参数控制滚刷和动刀片的移动,从而实现不同模式的运行。
在一些实施例中,可选地,可增设检测装置对滚刷上的垃圾进行检测,即检测装置检测粘连在或缠绕在滚刷上的垃圾数量。从而以便于根据检测 装置提供的关于垃圾数量的信息,控制动刀片的运动状态。具体的控制方法为:确定滚刷处于工作状态,并且根据检测装置确定滚刷上的垃圾大于第一阈值时,控制动刀片处于运动状态;或控制动刀片处于运动状态,根据检测装置确定滚刷上的垃圾小于第二阈值时,控制动刀片停止运动。第二阈值不大于第一阈值。可以理解为,第一阈值可以与第二阈值相同,也可以不同。当第一阈值与第二阈值不同时,第二阈值小于第一阈值。

如图1所示,本申请的一个实施例提供的毛发切割组件100,包括壳体110、滚刷120、定刀片131和动刀片132。其中,滚刷120、定刀片131以及动刀片132均与壳体110连接,壳体110主要起到安装载体的作用。在一些实施例中,可选地,滚刷120能够沿转动轴线相对壳体110转动。可选地,如图1、图2和图3所示,滚刷120包括辊体121和设于辊体121周向侧壁的多排刷毛122。滚刷120的转动轴线可以理解为辊体121的转 动轴线。滚刷120的转动实质为辊体121带动刷毛122转动。清洁设备200进行清洁工作时,滚刷120接触地面,滚刷120的刷毛122将地面灰尘进行拍打并且将垃圾刷起、卷入至壳体110内。
在一些实施例中,可选地,定刀片131与壳体110相对固定。动刀片132能够相对定刀片131移动。可选地,动刀片132与定刀片131相抵。可选地,动刀片132具有第一工位与第二工位。动刀片132能够由第一工位向第二工位移动或由第二工位向第一工位移动。可选地,动刀片132沿滚刷120的转动轴线移动进行剪切。动刀片132在第一工位与第二工位之间相对定刀片131移动,动刀片132与定刀片131的相对运动形成有效剪切动作,对纤维状垃圾(比如缠绕在滚刷120上的毛发)进行切割。可选地,壳体110包括安装壳体111、第一支撑壳体112和第二支撑壳体113。滚刷120与安装壳体111连接,且滚刷120能够沿转动轴线相对安装壳体111转动。定刀片131与第一支撑壳体112连接,且动刀片132与第二支撑壳体113连接。第一支撑壳体112与安装壳体111连接,且第二支撑壳体113与安装壳体111连接。第一支撑壳体112与安装壳体111之间的连接方式为粘接或焊接等;第二支撑壳体113与安装壳体111之间的连接方式为粘接或焊接等。
在一些实施例中,可选地,定刀片131与动刀片132相对于滚刷120的周向方向相邻。可选地,定刀片131与动刀片132位于平面的同一侧。滚刷120的转动轴线所在的平面在随着滚刷120沿第一旋转方向转动时,此平面先后经过定刀片131与动刀片132。垃圾随滚刷120沿其旋转方向一起转动时,先接触不运动的定刀片131,在一定程度上能够对动刀片132进行保护,降低垃圾对动刀片的损伤,确保动刀片的有效使用时间,有利于提高动刀片对纤维状垃圾的切割效果。
至少一个定刀片131设于动刀片132沿滚刷120的周向方向的一侧,至少一个定刀片131设于动刀片132沿滚刷120的周向方向的另一侧。滚刷120的转动轴线所在的平面在随着滚刷120沿第二旋转方向转动的过程中,此平面经过动刀片132之前,平面经过至少一个定刀片131。第二旋转方向与第一旋转方向相反。动刀片132在沿滚刷120的周向方向的两侧中, 每一侧均设有至少一个定刀片131。可选地,第一旋转方向为正转,第二旋转方向为反转。无论滚刷120是正转还是反转,滚刷120的转动轴线所在的平面在随着滚刷120一起转动时,此平面都是先后经过至少一个定刀片131与动刀片132,确保随滚刷120一起转动的垃圾优先接触不运动的定刀片131,对动刀片132进行保护,降低垃圾对动刀片的损伤。考虑到定刀片131与动刀片132对纤维状垃圾的切割效果、占用空间大小、对动刀片132的保护程度、成本以及其它因素,根据实际需求对定刀片131的数量以及动刀片132的数量进行灵活设置。
如图1所示,定刀片131的齿尖侧朝向滚刷120设置,动刀片132的齿尖侧朝向滚刷120设置。通过将刀片的齿尖侧朝向滚刷120设置,粘连在滚刷120上或缠绕在滚刷120上的垃圾有一部分能够被刀片在齿尖侧的刀刃划开,以解除缠绕并吸走,有利于提高清洁设备200的清洁效果。
在一些实施例中,可选地,在一些实施例中,可选地,动刀片132具有第一工位和第二工位,动刀片132能够由第一工位向第二工位移动或由第二工位向第一工位移动。可选地,动刀片132沿滚刷120的转动轴线移动进行剪切。动刀片132在第一工位与第二工位之间相对定刀片131移动,动刀片132与定刀片131的相对运动形成有效剪切动作,对纤维状垃圾(比如缠绕在滚刷120上的毛发)进行切割,有利于提高刀片的切割效果,进一步提高清洁设备200的清洁效果。
在一些实施例中,可选地,定刀片131的齿尖侧与滚刷120的转动轴线之间的距离为第一距离。处于第一工位的动刀片132的齿尖侧与滚刷120的转动轴线之间的距离为第二距离。处于第二工位的动刀片132的齿尖侧与滚刷120的转动轴线之间的距离为第三距离。第二距离大于第一距离,即处于第一工位的动刀片132的齿尖侧与滚刷120的转动轴线之间的距离大于定刀片131的齿尖侧与滚刷120的转动轴线之间的距离。第三距离大于第一距离,即处于第二工位的动刀片132的齿尖侧与滚刷120的转动轴线之间的距离大于定刀片131的齿尖侧与滚刷120的转动轴线之间的距离。总而言之,无论动刀片132处于第一工位还是处于第二工位,其齿尖侧与滚刷120的转动轴线之间的距离均大于定刀片131的齿尖侧与转动轴线之 间的距离。粘连在滚刷120上或缠绕在滚刷120上的垃圾优先接触不运动的定刀片131,有利于对动刀片132进行保护,降低垃圾对刀片的损伤。定刀片131的齿尖侧比动刀片132的齿尖侧更突出(更靠近滚刷120),避免人体直接触碰到动刀片132的刀尖造成伤害。
在一些实施例中,可选地,第二距离大于第三距离,即处于第一工位的动刀片132的齿尖侧与滚刷120的转动轴线之间的距离大于处于第二工位的动刀片132的齿尖侧与滚刷120的转动轴线之间的距离。动刀片132由第一工位向第二工位移动时,动刀片132逐渐靠近滚刷120;动刀片132由第二工位向第一工位移动时,动刀片132逐渐远离滚刷120。通过第三距离与第一距离的差值不小于0.1mm,一方面,确保第三距离大于第一距离,粘连在滚刷120上或缠绕在滚刷120上的垃圾先接触不运动的定刀片131,对动刀片132进行保护;另一方面,控制第三距离与第一距离的差值不会过大,保证动刀片132对纤维状垃圾的切割效果。
在一些实施例中,可选地,滚刷120的最大径向尺寸为滚刷120的最外边缘与转动轴线之间的距离。可选地,辊体121的半径加上刷毛122的长度,再减去刷毛122嵌入辊体121的长度,等于滚刷120的最大径向尺寸。第一距离不大于滚刷120的最大径向尺寸,即定刀片131的齿尖侧与滚刷120的转动轴线之间的距离小于或等于滚刷120的最大径向尺寸。当定刀片131的齿尖侧与滚刷120的转动轴线之间的距离小于滚刷120的最大径向尺寸时,表示定刀片131的齿尖侧能够伸入滚刷120中,以提高定刀片131对粘连在滚刷120上或缠绕在滚刷120上的垃圾的切割效果。在一些实施例中,可选地,第一距离与滚刷120的最大径向尺寸的差值不大于5mm,滚刷120的最大径向尺寸减去第一距离的差值小于或等于5mm,定刀片131的齿尖侧伸入滚刷120的伸入长度小于或等于5mm,一方面,能够确保定刀片131本身的切割效果;另一方面,避免定刀片131的齿尖侧伸入长度过大,影响刷毛122的伸展以及明显增大滚刷120的转动阻力。
在一些实施例中,可选地,第三距离不小于滚刷120的最大径向尺寸,即处于第二工位的动刀片132的齿尖侧与滚刷120的转动轴线之间的距离大于或等于滚刷120的最大径向尺寸。可以理解为,动刀片132的齿尖侧 不伸入至滚刷120中。在一些实施例中,可选地,第三距离与滚刷120的最大径向尺寸的差值不大于5mm,第三距离减去滚刷120的最大径向尺寸的差值小于或等于5mm,动刀片132的齿尖侧虽然不伸入滚刷120中,但其齿尖侧与滚刷120的最外边缘足够接近,确保动刀片132的切割效果。
在另一个实施例中,第一距离不小于滚刷120的最大径向尺寸,即定刀片131的齿尖侧与滚刷120的转动轴线之间的距离大于或等于滚刷120的最大径向尺寸。可以理解为,定刀片131的齿尖侧不伸入至滚刷120中,避免定刀片131的齿尖侧伸入滚刷120后,影响刷毛122的伸展以及明显增大滚刷120的转动阻力。在一些实施例中,可选地,第一距离与滚刷120的最大径向尺寸的差值不大于5mm,第一距离减去滚刷120的最大径向尺寸的差值小于或等于5mm,定刀片131的齿尖侧虽然不伸入滚刷120中,但其齿尖侧与滚刷120的最外边缘足够接近,确保定刀片131的切割效果。
如图12所示,毛发切割组件100还包括遮挡部150。具体地,遮挡部150与壳体110连接。遮挡部150设于定刀片131远离动刀片132的一侧。通过设置遮挡部150,一方面,可以起到遮挡灰尘的作用;另一方面,能够在一定程度上对定刀片131或动刀片132进行保护。可选地,遮挡部150与壳体110的安装壳体111连接。遮挡部150与安装壳体111之间的连接方式为粘接或焊接等。
在一些实施例中,可选地,毛发切割组件100还包括导引部160。具体地,导引部160与遮挡部150连接。导引部160朝远离定刀片131的方向延伸。通过设置导引部160,导引灰尘或垃圾,在很大程度上避免刀片与非纤维状垃圾接触,对刀片进行保护,降低垃圾对刀片组件的损伤。可选地,导引部160与遮挡部150为一体式结构,相对于后加工的方式而言,力学性能好,连接强度高,有利于减少零部件的数量,提高装配效率。
在另一个实施例中,滚刷120的数量为至少一个,即滚刷120可以是一个两个或者多个,考虑到清洁效果、占用空间大小、成本以及其它因素,根据实际需求对滚刷120进行灵活设置。在一些实施例中,可选地,定刀片131与动刀片132组成刀片组件。刀片组件的数量为至少一个,即刀片组件可以是一个、两个或者多个,考虑到切割效果、占用空间大小、成本以及其 它因素,根据实际需求对刀片组件进行灵活设置。在一些实施例中,可选地,滚刷120的数量不小于刀片组件的数量。可选地,滚刷120的数量为两个,且每个滚刷120均配有一个对应的刀片组件;或者,在两个滚刷120中仅有一个配有刀片组件。

如图13所示,根据本申请提出的一个实施例的毛发切割组件,主要包括驱动件102以及动刀片132和定刀片131,驱动件102起到提供主动力的作用,在偏心柱1082的作用下会驱使动刀片132进行往复移动,具体可相对于定刀片进行移动,从而实现对毛发的切割。具体地,动刀片132与驱动件102传动连接,驱动件会带动设于一侧的偏心柱转动,由于偏心轮108的一侧设置有偏心柱1082,动刀片132上设有第一限位孔1324,通过将偏心柱1082伸入到第一限位孔1324内,在转动时即可使得动刀片132沿第二方向运动。需要强调的,在动刀片132远离定刀片131的一侧设置有垫块109,如图15所示,通过在垫块109上设置受动部1092,偏心柱1082在带动动刀片132移动的同时,会在受动部1092的作用下带动垫块109也随之移动,可以理解,垫块109与动刀片132是一同移动的,在动刀片132上设置垫块109,可增大偏心柱与动刀片132之间的接触面积,从而将作用于动刀片132上的扭矩予以缩减,即原有力对全部作用于动刀片132上,动刀片132越厚,力的传递效率越高,磨损越小,但随之而来的是动刀片132单体的厚度的增加,不利于加工,而本申请是通过在动刀 片132上设置垫块109,将垫块109与动刀片132相连,利用垫块109变向的增大的动刀片132与偏心柱1082的接触面积,从而实现磨损的降低。
需要强调的,在一些实施例中,偏心柱伸入受动部使得动刀片沿第二方向运动,而对于动刀片132上是否设有第一限位孔1324,本申请不作限定。
可以理解,动刀片132上若不设置第一限位孔1324,可将偏心柱1082直接伸入到受动部处,也可以实现本实施例提到的降低磨损的效果。
可以理解,由于采用分体的垫块109,垫块109的材质可以选择较轻的耐磨材质,从而相比于直接对刀片做厚处理的方案,本申请的整个质量有所降低,同时耐磨程度也明显增强,极大的提高产品的竞争力。
此外,如果出现磨损,由于垫块109设置在动刀片132远离定刀片131的一侧,垫块109位于动刀片132的端部,会首先发生损坏,此时可进行单独更换,降低维修成本。
其中,动刀片132是沿第二方向延伸的,第一限位孔1324则是沿垂直于第二方向的第一方向延伸,例,动刀片132横向移动,第一限位孔1324竖向设置,从而使得偏心轮108在转动时,偏心柱1082会与第一限位孔1324配合,从而使得动刀片132沿第二方向移动。
可以理解,定刀片131的位置是固定,动刀片132通过偏心柱1082与驱动件102间接连接,在偏心柱1082和第一限位孔1324的共同作用下,即可使得动刀片132会相对于定刀片131发生移动,从而实现对毛发的切割效果。
其中,第一限位孔1324可以为孔状,也可以为长孔状。
需要补充的是,定刀片131和动刀片132之间是相邻设置的,以便于在动刀片132移动时,在刃部的作用下实现切割。

在一个具体的实施例中,额外设置一个偏心轮108,将偏心轮108上设置偏心柱1082,偏心轮108可直接套设在驱动件102的驱动轴上。
如图13所示,根据本申请提出的一个实施例的毛发切割组件,主要包括驱动件102、偏心轮108以及动刀片132和定刀片131,驱动件102起到 提供主动力的作用,在偏心轮108的作用下会驱使动刀片132相对于定刀片131进行往复移动,从而实现对毛发的切割。具体地,偏心轮108与驱动件102传动连接,驱动件102会带动偏心轮108转动,由于偏心轮108的一侧设置有偏心柱1082,动刀片132上设有第一限位孔1324,通过将偏心柱1082伸入到第一限位孔1324内,在转动时即可使得动刀片132沿第二方向运动。其中,动刀片132是沿第二方向延伸的,第一限位孔1324则是沿垂直于第二方向的第一方向延伸,例,动刀片132横向移动,第一限位孔1324竖向设置,从而使得偏心轮108在转动时,偏心柱1082会与第一限位孔1324配合,从而使得动刀片132沿第二方向移动。需要强调的,在动刀片132远离定刀片131的一侧设置有垫块109,通过在垫块109上设置受动部1092,偏心柱1082在带动动刀片132移动的同时,会在受动部1092的作用下带动垫块109也随之移动,可以理解,垫块109与动刀片132是一同移动的,在动刀片132上设置垫块109,可增大偏心柱与动刀片132之间的接触面积,从而将作用于动刀片132上的扭矩予以缩减,即原有力对全部作用于动刀片132上,动刀片132越厚,力的传递效率越高,磨损越小,但随之而来的是动刀片132单体的厚度的增加,不利于加工,而本申请是通过在动刀片132上设置垫块109,将垫块109与动刀片132相连,利用垫块109变向的增大的动刀片132与偏心柱1082的接触面积,从而实现磨损的降低。
在一个具体地实施例中,如图21所示,在受动部1092上设置凸起部1094,在凸起部1094内设置第二限位孔1096,在将垫块109与动刀片132相连时,可直接将凸起部1094伸入到第一限位孔1324内,即垫块109不仅在动刀片132的外侧起到保护作用,并且在第一限位孔1324内直接进行保护,凸起部1094相当于第一限位孔1324的孔套,偏心柱1082穿入凸起部1094上的第二限位孔1096,在偏心柱1082转动时,会直接作用受动部1092上的凸起部1094,即与偏心柱1082直接接触的结构均为垫块109,极大的提高对动刀片132的磨损保护效果。
在另一个具体的实施例中,垫块109和动刀片132之间是插入的连接关系,即动刀片132隐藏于垫块109内,垫块109在外侧对动刀片132起 到保护的作用,本方案中,如图20所示,受动部1092上设置有第三限位孔1098,在将动刀片132与垫块109装配完成后,第三限位孔1098和第一限位孔1324是相对的位置关系,偏心柱1082会依次直接穿过垫块109上一侧的第三限位孔1098、第一限位孔1324以及另一侧的第三限位孔1098,从而完成装配。
在另一个具体的实施例中,受动部上设有第四限位孔214,偏心柱位于第四限位孔214内。通过利用第四限位孔214和受动部,从而可实现驱动件对垫块和动刀片的驱动。
一个实施例中,如图18所示,偏心柱的尺寸大于偏心轮的尺寸。
另一个实施例中,如图19所示,偏心柱的尺寸小于偏心轮的尺寸,在偏心柱外设置有轴承216,轴承216与第四限位孔214相配合,将偏心轮与垫块的接触部位之间的摩擦由滑动摩擦变成滚动摩擦,有利于减小磨损和噪音。
如图13所示,根据本申请提出的一个实施例的毛发切割组件,主要包括驱动件102、偏心轮108以及动刀片132和定刀片131,驱动件102起到提供主动力的作用,在偏心轮108的作用下会驱使动刀片132相对于定刀片131进行往复移动,从而实现对毛发的切割。具体地,偏心轮108与驱动件102传动连接,驱动件102会带动偏心轮108转动,由于偏心轮108的一侧设置有偏心柱1082,动刀片132上设有第一限位孔1324,通过将偏心柱1082伸入到第一限位孔1324内,在转动时即可使得动刀片132沿第二方向运动。其中,动刀片132是沿第二方向延伸的,第一限位孔1324则是沿垂直于第二方向的第一方向延伸,例,动刀片132横向移动,第一限位孔1324竖向设置,从而使得偏心轮108在转动时,偏心柱1082会与第一限位孔1324配合,从而使得动刀片132沿第二方向移动。需要强调的,在动刀片132远离定刀片131的一侧设置有垫块109,通过在垫块109上设置受动部1092,偏心柱1082在带动动刀片132移动的同时,会在受动部1092的作用下带动垫块109也随之移动,可以理解,垫块109与动刀片132是一同移动的,在动刀片132上设置垫块109,可增大偏心柱与动刀片132之间的接触面积,从而将作用于动刀片132上的扭矩予以缩减,即原 有力对全部作用于动刀片132上,动刀片132越厚,力的传递效率越高,磨损越小,但随之而来的是动刀片132单体的厚度的增加,不利于加工,而本申请是通过在动刀片132上设置垫块109,将垫块109与动刀片132相连,利用垫块109变向的增大的动刀片132与偏心柱1082的接触面积,从而实现磨损的降低。
在一些实施例中,可选地,设置有第一壳体2062和第二壳体2064,从而可为定刀片131、动刀片132以及垫块109提供空间,具体地,定刀片131固定在第一壳体2062上,动刀片132和垫块109位于第一壳体2062和第二壳体2064连接所形成的空间内。
更进一步的,在两个壳体和定刀片131上设置第一销孔2102,在动刀片132上设置第二销孔2104,连接件2106在穿过三个结构上的第一销孔2102时,其位置是固定的,同时在连接件2106和第二销孔2104的配合下,会限制动刀片132的移动范围,仅能沿第二销孔2104的延伸方向,即第二方向做往复移动。
其中,连接件2106为销钉。
在一个具体的实施例中,定刀片131的位置只有一种,设置在第一壳体2062上,其数量可以为一个,也可以为多个。
在一个具体的实施例中,定刀片131根据位置分为两种,如图16所示,即第一刀片1314和第二刀片1316,两种定刀片131分别固定在第一壳体2062和第二壳体2064上,通过将动刀片132设置在两种定刀片131之间,从而可使得两种定刀片131均可起到对动刀片132的保护作用。即在出现石子等颗粒状的坚硬垃圾时,定刀片131由于其位置较为固定,抗冲击能力更强,通过将第一刀片1314和第二刀片1316分别设置在动刀片132的两侧,从而使得无论从哪个方向,垃圾会有限接触不运动的定刀片131,对动刀片132进行保护,降低垃圾对刀片的损伤。
在一些实施例中,可选地,考虑到定刀片131与动刀片132对纤维状垃圾的切割效果、占用空间大小、对动刀片132的保护程度、成本以及其它因素,根据实际需求对定刀片131的数量以及动刀片132的数量进行灵活设置。
在上述任一实施例的基础上,定刀片131上设有第一刀齿1312,动刀 片132上设有第二刀齿1322,第一刀齿1312和第二刀齿1322分别设置在定刀片131和动刀片132的同侧,例如第一刀齿1312的下侧设置定刀片131,第二刀齿1322的下侧设置动刀片132,从而在驱动动刀片132相对于定刀片131往复运动时,即可实现对毛发的切断。需要强调的是,本方案中,第一刀齿1312和第二刀齿1322均是间隔设置的,同时每个第一刀齿1312均与一个第二刀齿1322对应设置,动刀片132在往复运动的过程中,第二刀齿1322的运动的行程会处于对应的两个第一刀齿1312之间,以最短的行程实现对毛发的切割。
此外,本方案中第一刀齿1312和第二刀齿1322的位置并不均匀设置,而是采用不规则错位的对应设置关系,即第一刀齿1312的左侧和第二刀齿1322的左侧之间存在一定的距离差,该距离差可在0.1mm至2mm之间浮动,对于第一刀齿1312和第二刀齿1322而言,采用不均匀的分布,可提高对毛发的切割效果。
可以理解,第一刀齿1312和第二刀齿1322均位于第一壳体2062和第二壳体2064的外部,从而实现对外部毛发的切割。
其中,定刀片131上的第一刀齿1312可以根据定刀片131的位置选择单侧开刃,或者双侧开刃。
此外,如图14所示,在第一壳体2062内设置支撑件2082,第二壳体2064内设置滑条2084,在支撑件2082的作用下,会使得定刀片131和动刀片132之间处于紧贴状态,同时在滑条2084的作用下,会使得动刀片132的滑动更为顺畅。
在一个实施例中,在第一壳体2062的一端设置第一梳齿2122。
在另一个实施例中,在第二壳体2064的一端设置第二梳齿2124。

如图22所示,根据本申请提出的一个实施例的毛发切割组件100,主要包括驱动件102、主动件104和传动轮106,驱动件102起到提供主动力的作用,主动件104和传动轮106作为减速器,最终将驱动件102的转动转换为对传动杆4110的横向驱动。具体地,主动件104直接套设在驱动轴 1022上,驱动轴1022转动会带动主动件104一同转动,在主动件104和传动轮106的啮合作用下,会使得传动轮106也发生转动。
在一个实施例中,偏心柱1082直接与动刀片相连,以带动动刀片132发生横向移动。
在另一个具体的实施例中,还设有传动杆4110,通过传动杆4110可实现偏心柱1082和动刀片132的间接连接,传动轮106的轴线相对于驱动轴1022的轴线是不平行的,在传动杆4110沿第二方向延伸的情况下,传动轮106的轴线会与传动杆4110错开设置。
在一些实施例中,可选地,在传动杆4110沿第二方向延伸的情况下,传动轮106的轴线与传动杆4110之间也是不平行的,在此基础上,由于采用主动件104的结构,可使得主动件104的轴线与传动杆4110的延伸方向大体上是平行的,进而会对驱动件的位置予以限制,使其从大体垂直于传动杆4110的延伸平面的方向错开,利用大体上平行的位置,使得整个驱动组件的厚度方向的尺寸,即传动轮106的轴线方向上的尺寸有所减小。
其中,主动件与驱动轴之间的连接为套设,即主动件套设于驱动轴上。
需要强调的是,限位孔的截面形状可以是椭圆形,也可以为跑道型,当然,限位孔可以为通孔,传动杆直接穿透,或限位孔可以为盲孔,对传动杆起到一定的限位作用。
需要补充的是,还设置有偏心柱1082和传动杆4110,在传动杆4110的作用下会带动刀片132进行往复移动,从而实现对毛发的切割,通过将偏心柱1082伸入到沿第一方向延伸的限位孔41102内,偏心轮108转动时,偏心柱1082的运动轨迹呈圆形,由于限位孔41102是沿第一方向延伸的,故而偏心柱1082会带动限位孔41102横向移动,进而使得传动杆4110可以带动动刀片132在第二方向上做往复运动,以便于实现对毛发的切割。
在一些实施例中,可选地,驱动件102可选择普通电机或减速电机。
其中,传动杆4110的第一方向为限位孔41102的延伸方向,在一个具体地实施例中,为上下方向,第二方向则为传动杆4110的延伸方向,换言之,第一方向的第二方向均为传动轮106的径向方向,且第一方向和第二方向相互垂直。
在一些实施例中,可选地,驱动轴1022沿第二方向延伸,可使得驱动件102平行于传动杆4110设置,从而利用传动杆4110的横向空间,可容纳驱动件102,进一步缩减整个毛发切割组件100的厚度方向的尺寸,即传动轮106的轴线方向上的尺寸有所减小。
其中,驱动轴1022为驱动件102对外传递扭矩的主要结构,驱动件102整个结构一般均为绕驱动轴1022设置,故而通过限制驱动轴1022的延伸方向,即可对驱动件102的位置进行限制,进而可实现对毛发切割组件100整体厚度方向尺寸的缩减。
其中,还设置有与传动轮106同轴连接的偏心轮108,在径向方向上可减少空间的占据,即传动轮106受主动件104驱动进行转动时,会直接带动偏心轮108转动,由于偏心轮108远离传动轮106的一侧设有偏心柱1082,对于偏心轮108而言,可以为圆轮,也可以为凸轮,只要能够使得偏心轮108的重心与旋转中心错开即可。换言之,偏心柱1082的凸起方向所在直线与偏心轮的旋转轴线并不重合。
需要补充的是,第一方向和第二方向大体相垂直,可以为两个方向之间的夹角位于70°~110°之间。
如图22所示,根据本申请提出的一个实施例的毛发切割组件100,主要包括驱动件102、主动件104、传动轮106以及传动杆4110,驱动件102起到提供主动力的作用,主动件104和传动轮106作为减速器,最终将驱动件102的转动转换为对传动杆4110的横向驱动。具体地,主动件104直接套设在驱动轴1022上,驱动轴1022转动会带动主动件104一同转动,在主动件104和传动轮106的啮合作用下,会使得传动轮106也发生转动。本实施例中,传动轮106的轴线相对于驱动轴1022的轴线是垂直的,在传动杆4110沿第二方向延伸的情况下,传动轮106的轴线会垂直于传动杆4110设置,在此基础上,由于采用主动件104的结构,可使得主动件104的轴线平行于传动杆4110的延伸方向,即主动件104的轴线也沿第二方向延伸,进而会对驱动件102的位置予以限制,使其从垂直于传动杆4110的延伸平面的方向错开,利用平行的位置,使得整个毛发切割组件100的厚度方向的尺寸,即传动轮106的轴线方向上的尺寸有所减小。
在一些实施例中,可选地,设置减速壳体4112,可将主动件104、传动轮106、偏心轮108等结构设置在减速壳体4112内,仅需将偏心柱1082和驱动件102分别伸出减速壳体4112,具体地,偏心柱1082朝向传动杆4110设置,驱动件102则设置在减速壳体4112的侧面。
在一个实施例中,减速壳体朝向动刀片的侧壁上设有通孔,偏心轮位于通孔内。
在另一个实施例中,驱动件102位于减速壳体4112的外侧。
在一些实施例中,可选地,驱动件102位于减速壳体沿第二方向的外侧,从而一方面降低减速壳体4112的体积,另一方面也便于驱动件102的散热。
此外,还可设置传动轴4114,以实现传动轮106和偏心轮108之间的连接,具体地,传动轴4114的一端与传动轮106相连,传动轮106转动时,会带动传动轴4114一同转动,再通过将传动轴4114的另一端伸入偏心轮108,可在传动轴4114转动的情况下,带动偏心轮108一同转动,进而在限位孔41102的作用下,会驱动传动杆4110沿第二方向实现直线往复直线。
需要补充的是,传动轴4114的截面形状可以为圆形,也可以呈弓形,甚至可以为任意多边形。
在一个实施例中,主动件为蜗杆,传动轮106可选为斜齿轮,与主动件104进行配合,在主动件104的驱动作用下即可实现传动轮106的转动。
在另一个实施例中,主动件为蜗杆,传动轮106可选为蜗轮,通过将蜗轮与主动件104进行配合,对于蜗轮和主动件104而言,存在自锁功能,只能由主动件104作为主动件,将动力传递至蜗轮处,而不能反向传递动力,提高对驱动件102的保护。
在另一个实施例中,主动件为锥齿轮,传动轮为锥齿轮。
在另一个实施例中,主动件为直齿轮,传动轮为冠轮。
如图23和图24所示,根据本申请提出的一个实施例的毛发切割组件100,包括相邻设置的定刀片131、动刀片132以及驱动件102、主动件104、传动轮106以及传动杆4110,定刀片131的位置固定,动刀片132通过连接到传动杆4110上,在传动杆4110沿第二方向所在直线做往复运动时, 即可使得动刀片132会相对于定刀片131发生移动,从而实现对毛发的切割效果。驱动件102起到提供主动力的作用,主动件104和传动轮106作为减速器,最终将驱动件102的转动转换为对传动杆4110的横向驱动。具体地,主动件104直接套设在驱动轴1022上,驱动轴1022转动会带动主动件104一同转动,在主动件104和传动轮106的啮合作用下,会使得传动轮106也发生转动,由于传动轮106的轴线相对于驱动轴1022的轴线是垂直的,在传动杆4110沿第二方向延伸的情况下,传动轮106的轴线会垂直于传动杆4110设置,在此基础上,由于采用主动件104的结构,可使得主动件104的轴线平行于传动杆4110的延伸方向,即主动件104的轴线也沿第二方向延伸,进而会对驱动件102的位置予以限制,使其从垂直于传动杆4110的延伸平面的方向错开,利用平行的位置,使得整个毛发切割组件100的厚度方向的尺寸,即传动轮106的轴线方向上的尺寸有所减小。
需要补充的是,还设置有偏心轮108和传动杆4110,在传动杆4110的作用下会带动刀片132进行往复移动,从而实现对毛发的切割,偏心轮108与传动轮106同轴连接,在径向方向上可减少空间的占据,即传动轮106受主动件104驱动进行转动时,会直接带动偏心轮108转动,由于偏心轮108远离传动轮106的一侧设有凸起,即偏心柱1082,通过将偏心柱1082伸入到沿第一方向延伸的限位孔41102内,偏心轮108转动时,偏心柱1082的运动轨迹呈圆形,由于限位孔41102是沿第一方向延伸的,故而偏心柱1082会带动限位孔41102横向移动,进而使得传动杆4110在第二方向上做往复运动。
需要补充的是,定刀片131和动刀片132之间是相邻设置的,以便于在动刀片132移动时,在刃部的作用下实现切割。
其中,动刀片132连接至传动杆4110上,驱动件102平行于动刀片132设置,驱动轴1022会平行于动刀片132的延伸方向,通过利用动刀片132侧面的空间,可减小整个毛发切割组件100在动刀片132的厚度方向上的尺寸。
在一些实施例中,可选地,定刀片131上设有第一刀齿1312,动刀片132上设有第二刀齿1322,第一刀齿1312和第二刀齿1322分别设置在定 刀片131和动刀片132的同侧,例如第一刀齿1312的下侧设置定刀片131,第二刀齿1322的下侧设置动刀片132,从而在驱动动刀片132相对于定刀片131往复运动时,即可实现对毛发的切断。需要强调的是,本方案中,第一刀齿1312和第二刀齿1322均是间隔设置的,同时每个第一刀齿1312均与一个第二刀齿1322对应设置,动刀片132在往复运动的过程中,第二刀齿1322的运动的行程会处于对应的两个第一刀齿1312之间,以最短的行程实现对毛发的切割。
其中,对于动刀片132而言,第二刀齿的移动范围应不小于对应的两个第一刀齿的齿距,即第二刀齿的行程会经过对应于相邻的至少三个第一刀齿的范围。
在一个实施例中,第一刀齿1312和第二刀齿1322的位置并不均匀设置,而是采用不规则错位的对应设置关系,即第一刀齿1312的左侧和第二刀齿1322的左侧之间存在一定的距离差,该距离差可在0.1mm至2mm之间浮动,对于第一刀齿1312和第二刀齿1322而言,采用不均匀的分布,可提高对毛发的切割效果。
其中,相邻的两个第一刀齿1312之间为第一齿距,对应的相邻两个第二刀齿1322之间存在第二齿距,第一齿距和第二齿距之间的绝对差值为0.1mm~2mm。
其中,第一刀齿1312的齿宽为第一齿宽,对应的第二刀齿1322的齿宽为第二齿宽,第一齿宽和第二齿宽之间的绝对差值为0.1mm~2mm。
在一些实施例中,可选地,还设置切割壳体206,从而可为定刀片131提供固定位置,即将定刀片131固定在切割壳体206上,通过在切割壳体206的相对两侧壁设置滑孔,以便于传动杆4110的左右滑动,从而可使得动刀片132相对于定刀片131进行移动,进而实现对毛发的切割。
可以理解,滑孔设置在切割壳体206中的两个侧壁上,该侧壁是沿第二方向设置的,传动杆4110的两端分别插入到一个侧壁的滑孔内,传动杆4110即可在驱动件102的作用下实现左右横向往复移动,以便于实现切割。
对于定刀片131和动刀片132而言,为了提升切割效果,如图24所示,需要将二者保持紧贴,在一个实施例中,在动刀片132的外侧,即远离定刀 片131的一侧设置扭簧结构208,可通过扭簧提供的弹性力,将动刀片132与定刀片131紧紧相邻,从而可提高对毛发的切削效果。
在一个实施例中,可将定刀片131和动刀片132中的一个做磁性处理或直接采用磁性材料制造,在此基础上,可在不做磁性处理的刀片的外侧设置磁性件,例如,定刀片131具有磁性,在动刀片132远离定刀片131的一侧设置磁性件,通过磁性件与定刀片131的配合,可将动刀片132压紧至定刀片131处。
在另一个实施例中,如图25所示,在两种刀片上分别设置两种磁性件,即定刀片131上设置第一磁性件2142,动刀片132上设置第二磁性件2144,可通过磁吸力使得动刀片132贴在定刀片131上,从而便于切割。需要说明的是,对于磁性件而言,其存在N极和S极,本方案中,仅需保证在动刀片132进行往复直线运动的过程中,第一磁性件2142和第二磁性件2144之间是相互吸引保持不变,不会变为排斥力即可。
如图26和图27所示,根据本申请提出的一个实施例的清洁设备200,包括设备壳体302以及位于设备壳体302内的毛发切割组件100,通过在设备壳体302内设置一个或多个滚刷3022,在将地面上的毛发缠绕在滚刷3022上时,会通过毛发切割组件100对滚刷3022上的毛发进行切割,从而保证后续长效的清洁效果。
其中,滚刷3022的数量可以为一个,也可以为多个。
在一个实施例中,选用双滚刷3022的结构,此时可将毛发切割组件100设置在与两个滚刷3022相对应的位置上。
在另一个实施例中,选用单滚刷3022的结构。
其中,清洁设备200包括但不限于吸尘器、洗地机、扫地机器人等可对地面上灰尘、毛发进行收集清洁的设备。
在一些实施例中,可选地,设置控制器304,可对动刀片132的移动以及滚刷3022的转动进行控制,从而提高产品的智能化。
以上结合附图详细说明了本申请的实施例,通过本申请的实施例,由于第一距离非零,故而切割面并不是完全沿滚刷的径向延伸的,通过限制第一距离小于滚刷的最大半径尺寸,可使得在滚刷上缠绕有毛发时,更便 于接触到切割面进行切割,保证毛发切割组件的长久使用。
