Description

泵送装置 技术领域
本发明涉及产品分配领域，尤其涉及一种可用于从容器分配诸如液体、乳液之类的流动性和半流动性物料的泵送装置，例如按压泵、手扣式泵等。
背景技术
在用于容纳诸如卫生洗护产品、药品、食品等产品的容器中，通常会设置一个泵送装置，用于从容器中将产品分配出来。市场上可获得的常规的泵通常设置有金属制的弹性机构、例如金属弹簧，以向泵的诸如按压头之类的活动部件提供偏置力，从而赋予这些活动部件往复运动的能力。
在使用过程中发现，金属制的弹性机构存在缺陷。首先，金属弹性部件会在产品中长期浸泡，从而产生锈蚀，锈蚀所生成杂质会污染料液。其次，在一般的产品泵送装置中，除了金属弹性部件之外，为了降低制造成本，其余的部件通常都是由塑料制成。这样，在使用完之后回收该泵送装置时，需要将泵送装置拆解，将金属弹性件与其它的塑料部件分开，并分别回收。这样，会对回收利用的效率产生影响。
为了解决该问题，提高泵送装置的回收再利用的效率，需要具有新的结构设计的泵送装置，该泵送装置能够解决金属弹性件容易生锈而产生污染的问题，并且又能够提供与技术弹簧相同或相近的弹性特性。
发明内容
本发明是基于以上所述现有技术所存在的问题而做出的。本发明的目的是提供一种结构新颖的泵送装置，其允许高效地回收再利用。进一步地，该泵送装置的结构允许使用塑料材料来制造弹性件，并能够避免塑料制成的弹性件因长时间受压而屈服变形，导致弹力降低。
本发明的泵送装置具有活动部件和固定部件，活动部件能够相对于固定部件往复运动，从而经由与固定部件相连接的吸管将容纳在容器中的产品分配出来，其中，泵送装置包括弹性件，弹性件的一端支承或连接在活动部件上， 弹性件的另一端支承或连接在容器上，或者经由固定部件而支承于容器上。
因此，通过具有上述结构的泵送装置，其中的弹性件直接或间接地支承或连接在容器上，特别是能够支承在容器上，由此对弹性件的尺寸设计有更大的灵活性，允许采用较大尺寸的弹性件。这样，在使用塑料制造弹性件的情况下，也能保证获得所需的弹力。
具体地，活动部件可包括：按压头；以及活塞杆，活塞杆连接在按压头上；固定部件可包括：牙套，牙套连接在容器的瓶口处；汽缸，汽缸与牙套相连，容纳在容器中，并与吸管相连接，活塞杆延伸到容器内部；其中，弹性件的一端抵接或固定在按压头或活塞杆上。
其中，弹性件的另一端抵接或固定在以下位置中的一个上：容器的瓶肩上，容器底部的外侧表面上，容器的底部内表面上，以及形成在容器内部的台阶部上。
在一种实施方式中，弹性件的另一端固定在容器的瓶口上，其中，弹性件包括上环、下环和在上环和下环之间延伸的至少一根弹性条，并且，从下环向上还延伸有至少一根固定条，固定条向上连接到固定环，固定环固定在瓶口。
较佳地，泵送装置还包括放松机构，放松机构能够在放松位置和预加载位置之间切换，其中，弹性件在放松机构处于放松位置时的高度大于弹性件在放松机构处于预加载位置时的高度。通过放松机构的设置，可在不使用时使弹性件处于放松状态，从而避免或减少弹性件的屈服变形。
较佳地，放松机构包括同步套环，在按压头上设置有第一致动件，在同步套环上设置有第二致动件，通过第一致动件与第二致动件之间的相互作用，使放松机构在放松位置和预加载位置之间切换。
进一步地，第一致动件是形成在按压头上的第一凸块，在第一凸块上形成有第一斜面，第二致动件是形成在同步套环上的第二凸块，在第二凸块上形成有第二斜面，第一斜面与第二斜面相配合。
较佳地，同步套环套设在牙套上，其中，在同步套环的内表面上形成有狭槽，在牙套的外表面上形成有导轨，导轨与狭槽相配合，由此引导同步套环相对于牙套沿泵送装置的纵向的运动，并且阻止同步套环相对于牙套的旋转运动。
在本发明的泵送装置中，弹性件可由塑料制成。
在一种具体的优选结构中，活动部件包括：按压头；以及活塞杆，活塞杆连接在按压头上，其中，按压头上设置有按压凸缘，使用人的手指可扣在按压凸缘上以对按压头施加压力；
固定部件包括：牙套，牙套连接在容器的瓶口处；汽缸，汽缸与牙套相连，容纳在容器中，并与吸管相连接，活塞杆延伸到容器内部；
其中，弹性件的一端抵接或固定在按压头或活塞杆上，且另一端抵接或固定在牙套上。
进一步地，在弹性件上设置有导向块，而在牙套中形成有凹陷部，弹性件能够在放松位置和预加载位置之间转动，在放松位置中，导向块位于凹陷部内，而在预加载位置中，导向块离开凹陷部，使得弹性件的上端和下端之间的距离减小。由此，实现对弹性件的预加载和放松功能。
此外，弹性件还形成有同步套管，按压头包括按压头下圈套设在同步套管上，其中，在同步套管外表面和按压头下圈的内表面的一方上形成有凸筋，在另一方上形成有凹槽，凸筋和凹槽相互配合，使得弹性件能够随按压头一起转动。
弹性件可以设置在按压头和/或牙套的外部，或者也可隐藏在按压头和/或牙套的内部。例如，可在按压头的下部形成有下套筒，牙套的上部则形成有上套筒，通过下套筒和上套筒之间的相互配合，形成内部空间，弹性件被容纳在该内部空间中。

在本发明的公开内容中，所使用的“上”、“下”等表示方向或方位的用语都是以装置的在使用状态下所采取的朝向为准。
<第一实施例>
图1～2示出了本发明的第一实施例的泵送装置100，其中图1示出了该泵送装置100的放松位置，图2示出了该泵送装置100的预加载位置，图3则示出了该泵送装置100的立体图。
如图所示，在容器20上安装有泵送装置100。泵送装置100包括按压头110，按压头110可相对运动地联接于牙套120。牙套120固定连接在容器20的出口处，并且在牙套120上连接有泵送装置100的汽缸130。按压头110上联接有活塞杆140，该活塞杆140上连接有活塞(未在图中示出)，并且活塞杆140的连接有活塞的一端伸入到汽缸130中。
在本发明的泵送装置100中还包括弹性件150，该弹性件150的一端为固定端，支承在容器20上，另一端为活动端，支承在由按压头110等所组成的活动部件上。
对于图1和2所示结构的泵送装置100来说，通过对按压头110进行按压，活塞杆140连同其所连接的活塞在汽缸130中向下运动，从而将容器中的产品泵送出来。在撤去施加在按压头110上的压力之后，弹性件150的弹力使按压头110连同活塞杆140和活塞一起向上回复到其初始位置，以待下一次分配产品。在本发明中，弹性件150也可由塑料制成，从而在回收再利用时无需 再将它与泵送装置100的其余部分分开。该弹性件150的具体结构将在以下详细描述。
较佳地，在泵送装置100中还包括放松机构，该放松机构可在放松位置和预加载位置之间运动，在放松位置中，弹性件150处于放松状态，而在预加载位置中，弹性件150被略为加载。在如图1～3中所示的示例性结构中，该放松机构包括与按压头110相接触地设置的同步套环160。
下面将分别描述泵送装置100的各组成部件的较佳的结构。
图4示出了泵送装置100的按压头110的立体图。其中，该按压头110具有按压凸缘111，在操作泵送装置100时，使用人的手指可扣在该按压凸缘111上进行施力，以下压按压头110。在按压凸缘111的下侧设置有第一凸块112，该第一凸块112上形成有第一斜面113。
相对应地，图5示出了设置在按压凸缘111下方的同步套环160。在该同步套环160的面对按压凸缘111的上表面上设置有第二凸块161，在第二凸块161上形成有第二斜面162。第二斜面162可与第一凸块112上的第一斜面113相配合。随着按压头110相对于同步套环160旋转，第一斜面113将与第二斜面162相互作用，从而改变同步套环160与按压凸缘111之间的距离。
图6示出了牙套120的立体图。其中，至少在牙套120上部的外表面上形成有至少一个导轨121，而在同步套环160的内表面上形成有至少一个狭槽163，该狭槽163与导轨121相配合，使得同步套环160能够在牙套120的相应部分上滑动但不会绕着牙套120旋转。
图7中示出了弹性件150的立体图。其中，弹性件150包括上环151和下环152，至少一根弹性条153连接在上环151和下环152之间。如上所述的，如图7所示结构的弹性件150可由塑料制成，从而可避免常规的金属弹性件所存在的问题。
回到图1～3，其中显示第一实施例的泵送装置100中的弹性件150的上环151抵接在同步套环160上，下端支承在容器20的瓶肩21上。
当从图1所示的放松位置开始旋转按压头110时，按压头110将相对于牙套120旋转，而同步套环160则由于导轨121与狭槽163之间的作用而相对于牙套120在旋转方向上保持固定。这样第一斜面113与第二斜面162之间发 生相对作用，从而将同步套环160向下推离按压头110而进入图2所示的预加载位置。在该预加载位置中，由于同步套环160被向下推离按压头110一个距离H2，弹性件150的高度由图1中的H变为图2中的H1，其中H1小于H，从而使弹性件150略为加载。
而在使用好之后，可沿相反方向旋转按压头110，回到图1所示的状态，从而使弹性件150回到放松状态。
<第二实施例>
图8示出了本发明的第二实施例的泵送装置200。该第二实施例中的结构与第一实施例的相同之处在此不再详细描述，下面将重点描述第二实施例与第一实施例不同的特征。
如图8所示，在第二实施例的泵送装置200中，包括弹性件250，弹性件250也包括多根弹性条253。弹性件250的一端抵接在诸如按压头210之类的活动部件上。
弹性件250的另一端支承在容器20底部的外侧，具体来说是在容器20的底部外侧表面22上。例如，该容器20的底部外侧表面22可形成有外螺纹，弹性件250的下端可设置有带有内螺纹的部件，从而弹性件250的下端通过螺纹连接的方式固定在容器20的底部外侧。或者，弹性件250的下端(即固定端)也可通过其它方式固定在弹性件250的底部外侧上。
<第三实施例>
图9示出了本发明的第三实施例的泵送装置300。该第三实施例中的结构与第一和第二实施例的相同之处在此不再详细描述，下面将重点描述第三实施例与第一和第二实施例不同的特征。
如图9所示，泵送装置300包括按压头310，活塞杆340连接在按压头310上，随着按压头310运动。弹性件350的活动端(图中的上端)抵接或固定在活塞杆340上，弹性件350的固定端(图中的下端)固定在容器20的底部内表面上。
在该实施例中，弹性件350的活动端也可抵接或固定在其它活动部件上， 例如像第一实施例中那样抵接或固定在按压头310上。
<第四实施例>
图10示出了本发明的第四实施例的泵送装置500。该第四实施例中的结构与第一至第三实施例的相同之处在此不再详细描述，下面将重点描述第四实施例与第一至第三实施例不同的特征。
如图10所示，泵送装置500包括按压头510，活塞盖540连接在该按压头510上，弹性件550的活动端抵接或固定在该活塞杆540上。而在该第五实施例中弹性件550的固定端连接在容器20的瓶口24处。
具体来说，如图11中所示出的，除了上环551和下缓552之间的弹性条553之外，弹性件550的下端还连接有至少一根向上延伸的固定条555。该固定条555的另一端连接到固定缓554中，固定缓554固定在容器20的瓶口24处。
由此，从图10所示的剖视图来看，弹性件550的下端呈悬置状态，其由固定在瓶口24上的固定环554和从固定环554延伸而下的固定条555所保持。
<第五实施例>
图12示出了本发明的第五实施例的泵送装置600。该第五实施例中的结构与第一至第五实施例的相同之处在此不再详细描述，下面将重点描述第五实施例与第一至第五实施例不同的特征。
如图12所示，与之前的第四实施例相同的是，泵送装置600也包括按压头610，在按压头610上连接有活塞杆640，弹性件650的活动端抵接或固定在活塞杆640上。
在容器20的内部形成有台阶部25，弹性件650的固定端抵接在该台阶部25上。
<第六实施例>
图13～20d示出了本发明的第六实施例的泵送装置800。该第六实施例中的结构与第一至第五实施例的相同之处在此不再详细描述，下面将重点描述第六实施例与第一至第五实施例不同的特征。
图13和14分别示出了第六实施例的泵送装置800的正视图和立体图，图15和16示出了安装在容器20上的泵送装置800的剖视图，其中该泵送装置800分别处于放松位置和预加载位置。
如图所示，与第一实施例的泵送装置100一样，第六实施例的泵送装置800是手扣式的，包括按压头810和牙套820，按压头810上形成有凸缘，使用人可单手对该凸缘施力，以对按压头810进行按压。按压头810上连接有活塞杆840(见图15和16)，在牙套820上连接有气缸830，且该牙套820连接在容器20上、例如配合在容器20的瓶口上。泵送装置800还包括弹性件850。
第六实施例的泵送装置800的弹性件850的结构在图18a～18d中清楚地示出。其中，弹性件850包括上环851、下环852以及连接在上环851和下环852之间的至少一个、较佳地为多个的弹性条853。弹性件850还包括同步套管854，该同步套管854可一体形成在弹性件850上，例如与弹性件850的下环852一体形成，也可分体形成，然后再固定安装到弹性件850上。
回到图15和16，从中可以看到，在安装好的状态下，按压头810的下端套设在弹性件850的活塞杆840上，弹性件850的上环851抵接在按压头810上，下环852则与牙套820相接触，并经由该牙套820而支承在容器20上。
图19a～19c分别示出了弹性件850的剖视图、立体图和俯视图。从中可以看到，在牙套820上形成有凹陷部821，该凹陷部821中包括导向斜面822。与之相对应的，在弹性件850的下环852下方设置有导向块855，该导向块855包括与导向斜面822相对应的斜面857。
通过导向块855和凹陷部821之间的配合，可以实现对弹性件850的预加载，如在下文中具体描述的。
进一步地，如图18c中更清楚地示出的，在同步套管854的外表面上形成有至少一个凸筋856，而对应地，如图20a～20d中所示的，在按压头810的按压头下圈811的内表面上形成有凹槽812。在凸筋856和凹槽812之间的相 互作用下，弹性件850能够随按压头810一同转动。
在此，凹槽和凸筋的设置位置可以互换，同样在本发明的范围之内，即，可在按压头下圈811的内表面上形成凸筋，而对应地在同步套管854的外表面上形成凹槽。
下面将结合图15～17来说明第六实施例的泵送装置800的动作原理。
在出厂时，泵送装置800处于图15所示的放松位置，此时，弹性件850上的导向块855在牙套820的凹陷部821中，从而弹性件850的上环851和下环852之间的距离较大，弹性件850处于松弛的状态。
在对泵送装置800进行操作来泵送容器20中的产品之前，使用人先转动按压头810，例如转动90度，使弹性件850随之一起转动。这样，在牙套820的凹陷部821中的导向斜面822与弹性件850的导向块855上的斜面857的相互作用下，导向块855从凹陷部821中爬升出来，使得弹性件850的上环851和下环852之间的距离缩短，从而弹性件850进入到图16所示的预加载位置。
在预加载位置下，使用人可向下按压按压头810，从而将容器20中的产品泵送出来。
在使用好之后，可选地，可往回转动按压头810，使弹性件850回到放松位置。
<第七实施例>
图21和22示出了本发明的第七实施例的泵送装置900。该第七实施例中的结构与第一至第六实施例的相同之处在此不再详细描述，下面将重点描述第七实施例与第一至第六实施例不同的特征。
如图21所示，第七实施例的泵送装置900与第一和第六实施例的泵送装置一样，是手扣式的，包括按压头910和牙套920。第七实施例的泵送装置900的不同之处在于，其中的弹性件950是设置在按压头910的内部。
具体来说，如图21所示，按压头910具有下套筒911，牙套920则形成有上套筒921。下套筒911和上套筒921互相配合，形成内部空间，弹性件950则设置在该内部空间中。
与第一实施例类似，弹性件950包括上环951、下环952和它们之间的弹 性条953，如图22的立体图所示。回到图21，其中显示了弹性件950的上环951支承在活塞杆930上的凸缘上。或者，在一种未示出的实施结构中，该上环951可支承在按压头910的下套筒911内的任何适当位置处，例如可支承在下套筒911的顶板上。
至于弹性件950的下环952，在图21所示的结构中，其支承在牙套920上，例如支承在牙套920的上套筒921的底板上，从而经由牙套920而间接地支承在容器上。或者，下环952也可直接支承在容器上，例如可直接支承在形成于容器的瓶口的内表面上所形成的凸环等。
<第八实施例>
图23～25b示出了本发明的第八实施例的泵送装置1000。该第八实施例中的结构与第一至第七实施例的相同之处在此不再详细描述，下面将重点描述第八实施例与第一至第七实施例不同的特征。
如图23所示，第八实施例中的泵送装置1000也是手扣式的，并且，类似于第七实施例，泵送装置1000的弹性件1050也是容纳在按压头1010的内部，且其上环1051支承在按压头1010上，或者可以如第九实施例那样支承在活塞杆1030上所形成的凸缘上，下环1052则支承在牙套1020上。
不同之处在于，第八实施例的弹性件1050所包括的两个或更多个弹性条1053位于不同的平面上。如图24a和24b所示的。或者，换言之，弹性件1050的各弹性条1053各自在不同的平面中变形。
图25a和25b分别示出了沿图23中的线A-A剖切而得到的弹性件1050的剖视图，其中分别示出了两种结构的弹性件1050。其中，在图25a中所示出的弹性件1050的弹性条1053的截面呈平直的形状，而图25b中示出的弹性件1050的弹性条1053的截面呈弧形。
以上对本发明的优选实施方式进行了描述。本领域技术人员在此基础上可以进行显而易见的变型和修改。其中：
在图中所示的结构中，弹性件包括上环和下环。不过，上环和下环中的一个可以省略，此时弹性条的相应端部直接连接在活动部件或容器上。
在第一实施例中，弹性件150与同步套环160是两个相互分开形成的部件，但弹性件150也可以与同步套环一体形成。
在以上对所公开的实施例的描述中，弹性件的上环和下环(或者说是上端和下端)是支承或连接在相应的部件中，其中包括弹性件的上环或下环一体地形成在相应部件上的情形。
在以上公开的实施方式中，将按压头、活塞杆等描述为泵送装置的活动部件，而汽缸、牙套等描述为泵送装置的固定部件。对于本领域技术人员来说，可以知道的是，对于不同类型的泵送装置，还会包括其它活动部件和固定部件，并且同一部件在一种类型的泵送装置中有可能是活动部件而在另一种类型的泵送装置中则有可能是固定部件。例如，同样是汽缸，其既可能是固定部件，也可能是活动部件。相对应地，当汽缸是固定部件时，活塞和活塞杆就是活动部件，而当汽缸是活动部件时，活塞和活塞杆则相应地就是固定部件。
在以上所公开的实施方式中，吸管30被显示为一个整体式的部件。该吸管可以通过注塑成型方式制成，也可通过挤出、吹塑等方式成型。此外，吸管还可包括多个组装在一起的部分。
