  • the water outlet device of the present invention can be installed on bathroom and kitchen faucets for use; when the faucet is turned on, water flows through the jet hole to the water flow channel and leaves the water outlet device from the water flow channel, thereby generating a first type of water outlet splash; at the same time, the water flow synchronously causes the slider to move axially in the first installation through hole toward the water outlet direction, so that the second support portion of the slider is separated from the first support portion of the water outlet member, and at the same time, the elastic element is in a state of accumulating rebound force; rotating the water outlet member during water flow can allow another water flow channel to dock with the jet hole, thereby allowing water to leave the water outlet device from the other water flow channel, thereby generating a second type of water outlet splash; at the same time, the rotation allows the water outlet member to The first support part of the member also rotates toward the second support part of the slider, so that the two are close to or pressed into contact; if the water flow stops during the generation of the second water splash, the elastic element releases the
  • the slider moves axially toward the water inlet direction under the action of the elastic element, so that the second support part of the slider presses and pushes the first support part, and the axial movement of the slider is converted into a rotation of the water outlet member in the circumferential direction through the pressure of the second support part on the first support part, until the slider returns to the initial axial position of the slider, and the water outlet member also returns to the initial circumferential position of the water outlet member.
  • the beneficial effect of the present invention is that no matter what water outlet state the water outlet device is in or what kind of water splash it produces during use, it will be restored to its initial state through the driving of internal parts after the water is turned off, so that the user can clearly know what kind of water splash the water outlet device will produce before each use of water, which will enhance the user experience of the water outlet device.

In addition, the annular water splash can also be high-pressure water.
  • the top surface of the slider 31 is exposed to the opening of the first mounting hole 12 at one end toward the water inlet side, so that after water is passed, the top surface of the slider 31 can be used to withstand the entire water pressure, thereby overcoming the elastic force of the elastic element 32 to allow the slider 31 to smoothly move axially in the first mounting hole 12 toward the water outlet direction, allowing the second support portion 311 of the slider 31 to disengage from the first support portion 211 on the water outlet component 20, ensuring that the water outlet component 20 can rotate without hindrance and maintain its position after rotation.
  • it also includes a water outlet panel connected to the water outlet end of the water outlet member 20; the elastic element 32 is clamped between the slider 31 and the water outlet panel, so as to ensure that the two can maintain a stable relative position in the absence of external force (the external force here includes water pressure and human force applied to rotate the water outlet member 20), that is, the slider 31 is located in the first mounting hole 12 at a position away from the water outlet end of the first mounting hole 12, and its second support portion 311 is pressed against the first support portion 211.

Description

出水装置 技术领域
本发明涉及卫浴领域，尤其是指一种出水装置。
 背景技术
现有的多功能起泡器、水龙头抽取头和花洒等卫浴用出水装置，常设置旋转外壳、推拉阀芯或按压按键等结构来切换出水装置的出水水道，从而产生形态不同的出水水花。
对上述出水装置，一般需要使用者进行主动操作才能切换到所需的出水状态，因此存在使用者使用完出水装置后、在下一次开启出水装置前，会遗忘上一次操作时将出水装置切换到何种出水状态，使用者无法确定出水装置将产生何种出水水花，这可能导致不恰当的出水水花会与使用环境发生冲击而产生飞溅。
 技术问题
本发明所要解决的技术问题是：提供一种出水装置，在关闭水源后可以恢复到初始出水状态。
 技术解决方案
为了解决上述技术问题，本发明采用的一种技术方案为：
一种出水装置，包括过水件和出水件，所述过水件上沿圆周方向设有多个射流孔，所述出水件上设有不同的水流道，所述过水件和所述出水件转动连接，所述射流孔通过所述过水件和所述出水件的相对转动接通不同的所述水流道，所述过水件沿轴向设有设有第一限位部；所述出水件沿轴向设有第一支撑部；还包括滑块和弹性元件，所述滑块包括第二支撑部和第二限位部；所述第一限位部连接所述滑块的第二限位部，使所述滑块仅可相对于所述出水件沿该出水件的轴向移动；所述弹性元件在轴向上支撑所述滑块；所述滑块的第二支撑部在轴向与所述第一支撑部相抵压或分离，且所述滑块和所述出水件能够通过所述第二支撑部和所述第一支撑部相对转动，以使所述射流孔与不同的所述水流道连通。
本发明的出水装置可安装在卫厨龙头上使用；当龙头通水后，水流通过射流孔向水流道射出并从该水流道离开出水装置从而产生第一种出水水花，同时，水流同步使滑块在第一安装通孔内沿轴向朝出水方向移动，让滑块的第二支撑部与出水件的第一支撑部分离，同时，弹性元件处于积蓄回弹力的状态；通水期间转动出水件可以让另一水流道对接射流孔，从而让水流从另一水流道离开出水装置从而产生第二种出水水花，同时，该转动让出水件的第一支撑部也朝向滑块的第二支撑部转动，使两者靠近或者抵压接触；若在产生第二种出水水花期间停止通水，弹性元件释放回弹力并恢复到初始状态，在该过程中，滑块在弹性元件的作用下沿轴向朝进水方向移动，使滑块的第二支撑部抵压并推动第一支撑部，滑块的轴向运动通过第二支撑部对第一支撑部的抵压转化为出水件在圆周方向上的转动，直至滑块回到滑块在轴向的初始位置时，出水件也回到出水件在圆周方向上的初始位置。
 有益效果
本发明的有益效果在于：出水装置在使用期间无论处于何种出水状态、产生何种出水水花，都将会在关水后通过内部零件的驱动恢复到初始状态，方便使用者在每一次用水前清楚地知道出水装置将产生何种出水水花，这将提升出水装置的使用体验。

 本发明的实施方式
为详细说明本发明的技术内容、所实现目的及效果，以下结合实施方式并配合附图予以说明。
请参照图1~图13，一种出水装置，包括过水件10和出水件20，过水件10上沿圆周方向设有多个射流孔11，具体指过水件10轴向的端面上设置有多个沿该端面的周向分布的射流孔11，出水件20上设有不同的水流道，过水件10和出水件20转动连接，射流孔11通过过水件10和出水件20的相对转动接通不同的水流道，过水件10沿轴向设有第一安装通孔12，第一安装通孔12的内壁沿轴向设有第一限位部121；出水件20沿轴向设有第二安装通孔21，第二安装通孔21的内壁设有第一支撑部211；还包括滑块31和弹性元件32，滑块31包括第二支撑部311和第二限位部312；滑块31设于过水件10的第一安装通孔12内，第一安装通孔12的第一限位部121连接滑块31的第二限位部312，使滑块31在第一安装通孔12内仅可沿轴向移动，弹性元件32在轴向上支撑滑块31；过水件10通过第一安装通孔12安装在出水件20的第二安装通孔21内，滑块31的第二支撑部311在轴向与第二安装通孔21的第一支撑部211抵压或分离，且滑块31和出水件20能够通过第二支撑部311和第一支撑部211相对转动，以使射流孔11与不同的水流道连通。
在龙头未通水的情况下，射流孔11对准一水流道，滑块31的第二支撑部311与出水件20的第一支撑部211充分靠近或处于抵压状态，并通过弹性元件32的支撑让滑块31处于稳定的位置；当龙头通水后，滑块31受水压压力的作用，并在水压压力大于弹性元件32的弹力时，滑块31在第一安装通孔12内沿轴向朝出水方向移动，该移动让滑块31的第二支撑部311与出水件20的第一支撑部211分离，弹性元件32处于积蓄回弹力的状态，与此同时，水流通过射流孔11向水流道射出并从该水流道离开出水装置从而产生第一种出水水花；通水期间，使用者可以转动出水件20（此时可以定义为出水件20朝第一方向发生转动）让另一水流道对接射流孔11，从而让水流从该水流道离开出水装置从而产生第二种出水水花，而对出水件20的转动会让出水件20的第一支撑部211也朝向滑块31的第二支撑部311转动，使两者的局部充分靠近或处于抵压状态，且因为水压的持续作用，弹性元件32继续保持处于积蓄回弹力的状态；若在产生第二种出水水花期间关闭水源停止向龙头通水，则弹性元件32在丧失了水压压力的约束后将会释放回弹力并恢复到初始状态，在弹性元件32恢复到初始状态的过程中，滑块31在回弹力的作用下沿轴向朝进水方向移动，使滑块31的第二支撑部311抵压并推动第一支撑部211转动，滑块31的轴向运动通过第二支撑部311对第一支撑部211的抵压转化为出水件20在圆周方向上的转动（此时出水件20朝与第一方向相反的第二方向发生转动），直至滑块31回到滑块31在轴向的初始位置时，出水件20也回到出水件20在圆周方向上的初始位置。
可以理解的是，在未通水的场景下，即使第二支撑部311与第一支撑部211处于初始位置，两者充分靠近或处于接触状态，出水件20也能在外力的作用下被转动（在所有实施例中出水件20都不会被锁定），但是在该状态下转动出水件20需要克服弹性元件32的支撑力，即外力需要施力于出水件20来让第一支撑部211驱动滑块31克服弹性元件32的支撑力朝第一安装通孔12的出水端移动，并在出水件20转动到终末位置后必须维持外力的作用才能将出水件20保持在切换后的位置上，一旦外力撤除，弹性元件32就会驱动滑块31回到原位从而带动出水件20回到初始位置。本方案中的弹性元件32可以采用压簧或扭力弹簧。
在一些实施例中，水流道设有两组，在出水件20的入水侧设有两组水流道的入口，第一组水流道23的入口和第二组水流道24的入口交错设置，在出水件20的出水侧设有两组水流道的出口，第一组水流道23的出口被第二组水流道24的出口包围，这样的设置能够实现内外圈的出水，即，第一组水流道23的出口在出水件20产生出水面积较大的集中水花，集中水花可以是气泡水、透明水、喷雾水、刀片水或多柱细水花构成的花洒水；第二组水流道24的出口在出水件20产生出水面积较小的环绕出水件20的轴线成形的环形水花，环绕轴线成形的环形水花可以是常规花洒水、多柱细水花构成的花洒水，此外，环形水花也可以是高压水。
在一些实施例中，滑块31的顶面暴露于第一安装通孔12朝向入水侧一端的开口，这样可以在通水后，让滑块31的顶面用来承受全部的水压压力，从而克服弹性元件32的弹力让滑块31顺利地在第一安装通孔12内沿轴向朝出水方向移动，让滑块31的第二支撑部311与出水件20上的第一支撑部211脱离，确保出水件20能够无障碍地转动并在转动后保持位置。
在一些实施例中，还包括与出水件20的出水端连接的出水面板；弹性元件32夹设于滑块31上和出水面板之间，从而确保两者在没有外力作用下（这里的外力包括水压压力和转动出水件20的人为施力）能保持相对位置的稳定，即：滑块31在第一安装通孔12内处于远离第一安装通孔12的出水端的位置、且其第二支撑部311抵压于第一支撑部211。
在一些实施例中，滑块31和第一安装通孔12之间设有密封件33，从而避免通水后水流从滑块31和第一安装通孔12之间溢出而导致最终输出的出水水花变形或滴水。密封件33可以采用O型密封圈，或者更优选地采用Y型密封圈。
在一些实施例中，第一支撑部211和第二支撑部311的至少一者为拟柱体；可选的，第一支撑部211和第二支撑部311的至少一者为楔体或长方体。为了实现滑块31在第一安装通孔12内进行轴向移动的同时可以驱动出水件20进行圆周方向的转动，支撑部采用了拟柱体、楔体或长方体的设计，即可让两者之间构成楔形机构将直线运动转化为旋转运动，即，第一支撑部211处于靠近进水方向的一侧、第二支撑部311处于靠近出水方向的一侧，第二支撑部311支撑第一支撑部211，将滑块31的轴向移动转化为出水件20的圆周方向转动，这种设计的传动效率最高，且结构简单、可靠性好。
在一些实施例中，第一限位部121和第二限位部312相嵌合，具体为凹槽和凸起配合，两个限位部可以任意一者设置为凹槽，另一者设置为凸起，这样可以确保滑块31能够严格沿着轴向进行移动，确保滑块31能够准确地驱动出水件20转动而不是让自身产生转动，传动效率高，能提高产品的可靠性。
在一些实施例中，第一安装通孔12的侧壁设有豁口122，第一支撑部211通过豁口122延伸至第一安装通孔12内，这样可以确保第一支撑部211和第二支撑部311之间能够更容易对准和在工作状态中相互接触和抵压。
在一些实施例中，过水件10上设有第一限位板13，出水件20上设有第二限位板22，第一限位板13和第二限位板22在圆周方向具有重合的移动轨迹，第一限位板13通过过水件10与出水件20的相对转动能够与第二限位板22相互抵压或分离，两个限位板的设置限制了出水件20相对过水件10的可转动角度，该角度设计为在两个限位板处于相互抵压状态时，过水件10上的多个射流孔11在轴向上的投影落入出水件20上设置的不同的水流道的入口，这就确保过水件10与出水件20在不同的转动极限位置上射流孔11的射出水流可以进入此时与其相对的水流道内，最终让水流通过水流道后向外部进行输出。
在一些实施例中，过水件10的第一安装通孔12的孔壁外侧设有凸台14，出水件20通过第二安装通孔21的孔壁底侧抵压于凸台14上与过水件10连接。这种结构较为简单和可靠，确保出水件20能够挂在过水件10上并进行转动来切换射流孔11与出水件20上的不同的水流道的连通。
在一些实施例中，滑块31为一体式结构。
在一些实施例中，滑块31为分体式结构。当滑块31为分体式结构时，滑块31包括承压件313和滑动件314，第二支撑部311和第二限位部312设置于滑动件314上，承压件313安装于滑动件314上，承压件313的承压端面位于过水件10的进水端，滑动件314位于靠近过水件10的第一安装通孔12的出水端处，弹性元件32与滑动件314相抵压。上述分体式结构易于装配，在具体安装时，先将过水件10安装在出水件20上，然后将承压件313从过水件10的一侧装入第一安装通孔12内，再将滑动件314从出水件20的一侧装入第一安装通孔12内，在装入滑动件314时，需要同时确保第二支撑部311对准第一支撑部211、和确保滑动件314与承压件313扣合。承压件313用于承受水流的压力，其迎水面需尽量设置得较大，若承压件313处于最高位置时与第一安装通孔12平齐，则其迎水面的面积会设置为尽量接近第一安装通孔12的孔口面积，若承压件313处于最低位置时高于第一安装通孔12，则其迎水面的半径会设置为尽量接近过水件10的中心至射流孔11之间的距离。
请参照图1至图13，本发明的实施例一为：
一种出水装置，可作为起泡器安装在龙头上使用，包括过水件10和出水件20。过水件10上沿圆周方向设有多个射流孔11，沿轴向设有第一安装通孔12，第一安装通孔12一面朝出水方向延伸、另一面朝进水方向的一侧设有开口，第一安装通孔12的内壁设有设置为呈凸起状的沿轴向延伸的第一限位部121，过水件10的外壁设有朝径向延伸的凸台14。出水件20上设有不同的水流道，出水件20的中心处沿轴向设有第二安装通孔21，不同的水流道的入口环绕第二安装通孔21，第二安装通孔21的孔壁内设有第一支撑部211。出水件20通过第二安装通孔21的出水端抵压于过水件10的第一安装通孔12的外壁的凸台14上，与过水件10可相对转动地连接，射流孔11通过过水件10和出水件20的相对转动以连通不同的水流道，射流孔11的数量为所有水流道的入口的数量之和的一半。
在本实施例中，水流道设有两组，在出水件20的入水侧设有两组水流道的入口，每组水流道具有8个入口，第一组水流道23的入口和第二组水流道24的入口交错设置，在出水件20的出水侧设有两组水流道的出口，第一组水流道23的出口被第二组水流道24的出口包围，这样的设置能够实现内外圈的出水，即，第一组水流道23的出口在出水件20产生出水面积较大的集中水花、第二组水流道24的出口在出水件20产生出水面积较小的环绕中心进行的环形水花，集中水花为气泡水，环绕中心进行的环形水花为多柱细水花构成的花洒水。
过水件10的外侧壁上设有第一限位板13，出水件20的外侧壁上设有第二限位板22，第一限位板13和第二限位板22之间具有圆周方向的转动空间，且第一限位板13和第二限位板22在圆周方向具有重合的移动轨迹，第一限位板13通过过水件10与出水件20的相对转动与第二限位板22相抵压或分离，第一限位板13与第二限位板22在处于两处相抵压状态时，射流孔11恰好对准不同水流道的入口。
过水件10的第一安装通孔12内沿出水方向依次设有滑块31和弹性元件32，弹性元件32设于第一组水流道23内并支撑滑块31。滑块31的顶面暴露于第一安装通孔12的进水端外，滑块31和第一安装通孔12之间设有密封件33。同时，第一安装通孔12的侧壁设有豁口122，第一支撑部211通过豁口122从径向伸至第一安装通孔12内。
滑块31为分体式结构，滑块31包括承压件313和滑动件314，第二支撑部311和第二限位部312设置于滑动件314上，承压件313安装于滑动件314上，承压件313的承压端面位于过水件10的进水端，滑动件314位于靠近过水件10的第一安装通孔12的出水端处，弹性元件32与滑动件314相抵压，承压件313处于最高位置时与第一安装通孔12平齐，承压件313的承压端面的面积小于第一安装通孔12的孔口面积。
滑块31装入第一安装通孔12后，其第二限位部312与第一安装通孔12的第一限位部121在轴向上以凹槽和凸起的配合结构相嵌合，确保滑块31只能在轴向进行移动而无法相对于过水件10发生周向转动，且承压件313的侧壁底端在滑块31在第一安装通孔12内处于最低位置时能够抵压在第一限位部121的顶端，确保滑块31不会从第一安装通孔12内掉落；同时，出水件20的第一支撑部211支撑滑块31的第二支撑部311，第一支撑部211和第二支撑部311都为楔体，第一支撑部211和第二支撑部311构成楔形传动机构，两者可沿楔体的斜面在出水件20的周向上和轴向上产生相对移动，具体地，第一支撑部211的楔体的斜面朝出水方向，第二支撑部311的楔体的斜面朝进水方向，在滑块31不受水压压力和出水件20不受外力作用时，弹性元件32能够支撑滑块31使其第二支撑部311始终抵压在第一支撑部211上，在该楔形传动结构的作用下，通过外力能够让滑块31沿轴向移动时带动出水件20产生圆周方向转动或者让出水件20产生圆周方向转动时带动滑块31沿轴向移动。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等同变换，或直接或间接运用在相关的技术领域，均同理包括在本发明的专利保护范围内。
