Description

塑料弹簧及其应用 技术领域
本发明涉及包装容器,特别涉及一塑料弹簧及其应用。
背景技术
乳液包装容器在日常生活中有广泛的应用,无论是个人洗护用的洗发水、沐浴露等产品,还是厨房清洁用的洗洁精等产品,均采用乳液包装容器进行包装。乳液包装容器通常提供一个乳液泵,其允许用户通过按压头帽的方式自容器内泵取乳液,通常情况下,乳液泵设置有一个供头帽复位的金属弹簧,当按压头帽时,金属弹簧被压缩产生变形而积蓄弹性势能,当释放头帽时,金属弹簧在恢复初始状态时向上推动头帽复位。采用金属弹簧的乳液泵存在较多的问题,例如,金属弹簧容易生锈,造成乳液泵失效或乳液污染,乳液包装容器在被回收时需要被拆解并将塑料制品和金属制品分类,回收难度大,回收成本高。为解决这些问题,塑料弹簧被发明和被使用,例如,在授权公告号为CN214987297U的中国发明专利中公开了一种高弹性塑料弹簧,其包括第一定位环和第二定位环,弹簧的前后端交叉设置有弹性部,弹性部的两端分别连接第一定位环和第二定位环,弹性部呈波浪形且至少设有一个弧面,弧面处均设有支撑环,第一定位环、第二定位环以及支撑环与弹性部之间容置腔,尽管弹簧在两个弹性部之间设置有支撑环,但是受限于两个弹性部和第一定位环、第二定位环的设置方式,在弹簧被挤压时,弹簧的弹性部仍然会出现向四周膨大的问题,而一旦弹簧的弹性部向四周膨大,必然造成弹性部剐蹭泵体的内壁,造成乳液泵的手感变差,甚至出现弹性部被泵体卡住而无法复位的问题。
另外,乳液包装容器在被使用时,向下按压乳液瓶的乳液泵的头帽,乳液泵的泵腔内的流体能够经头帽的头帽通道排出,并且在此时,乳液泵的弹簧被压缩而积蓄弹性势能,在撤销施加于乳液泵的头帽的压力时,弹簧在恢复初始状态的过程中向上推动头帽,以允许乳液瓶的瓶体内的流体补充至乳液泵的泵腔,供下次按压头帽时排出,如此实现流体的泵取。现有的乳液瓶的乳液泵通常处于弹开状态,在运输或携带乳液瓶时,为了防止乳液泵的头帽被误按压而出现漏液问题,乳液瓶通常提供一个罩盖,供罩住乳液泵的头帽,使用前将罩盖取下以暴露乳液泵的头帽,运输或携带时将罩盖罩住头帽以避免头帽被误按压。在运输或携带乳液瓶时,通过将罩盖罩住乳液泵的头帽的方式,虽然能够避免乳液泵的头帽被误按压,但是这种方式仍然存在着诸多的缺陷,具体如下。首先,由于需要提供罩盖罩住乳液泵的头帽,因此不仅增加乳液瓶的成本,而且还需要考虑如何可靠地将罩盖罩在乳液泵的头帽的外侧以避免运输或携带乳液瓶的过程中避免罩盖脱落,其次,通过将罩盖罩在乳液泵的头帽的外侧的方式导致乳液瓶在被运输或存储时的高度尺寸较大,需要占用更多的空间而增加了运输成本和存储成本。

具体实施方式
如图1至图4所示,本发明的第一个实施例揭露了一应用有塑料弹簧的泵芯结构,其包括一泵体1、一螺圈2、一头帽3、一连接座4、一活塞杆5及一塑料弹簧6。所述泵体1具有中空的一泵腔11,底部设置有一进液口12,顶部设置有敞口,所述进液口12和所述敞口分别在所述泵体1的底部和顶部连通所述泵腔11。所述螺圈2被连接于所述泵体1的顶部且具有对应所述泵体1的所述敞口的上下贯通的开口21。所述头帽3下部穿过所述螺圈2的所述开口21并与所述开口21导向配合,所述头帽3中设置有竖向延伸的一导流套31。
所述连接座4被设置于所述泵体10的所述泵腔11中且中部开有上下贯通的一装配口41,所述连接座4与其之上的所述泵腔11、所述头帽3内腔共同围合出一装配腔100。所述活塞杆5能上下移动地设 置于所述泵体10的泵腔11中,所述活塞杆5的上端与所述头帽3的所述导流套31相连接、下端穿过所述连接座4的所述装配口41布置。所述塑料弹簧6被设置于所述装配腔100中,所述塑料弹簧6套置在所述活塞杆5及所述导流套31外周,并且所述塑料弹簧6的上端与所述头帽3的内顶壁相抵、下端与所述连接座4的上表面相抵。
在本实施例中,所述活塞杆5的上端与所述导流套31的下端相插配连接,装配完毕状态下,所述活塞杆5外周壁与所述导流套31外周壁的直径差在0mm~6mm内。本实施例通过限制所述活塞杆5外周壁与所述导流套31外周壁的直径差,使二者与所述塑料弹簧6内壁之间的间隙基本一致,从而能更好的对所述塑料弹簧6的形变进行约束,使所述塑料弹簧6的形变更加规律,以进一步提高所述应用有塑料弹簧的泵芯结构的稳定性。
本实施例的所述活塞杆5上端设置有一插接部51,所述插接部51插置在所述导流套31中。上述的所述活塞杆5外周壁的直径小于所述导流套31外周壁的直径,所述活塞杆5的外周壁上设置有沿轴向延伸、用于对所述塑料弹簧6进行径向支撑的支撑筋52。该结构可利用较小的面积在径向上对所述塑料弹簧6进一步进行支撑,既能起到支撑所述塑料弹簧6的作用,又由于支撑面积小而不影响所述活塞杆5与所述导流套31整体对所述塑料弹簧6的支撑均匀性,从而使所述塑料弹簧6的形变更加规律。
在本实施例中,所述螺圈2的所述开口21处设置有沿轴向延伸的所述导向圈22,装配完毕状态下,所述导向圈22的内周面与所述泵体10的所述泵腔11上部的内周面大致对齐从而形成与所述头帽3外周壁导向配合的一导向面200。该结构有利于提高所述头帽3上下移动的稳定性。所述头帽3下部的外周壁与所述导向面200之间的间距为0.05mm~0.4mm之间。由于本实施例的所述塑料弹簧6长度可以做到较大,可以理解的是,单独存在的所述塑料弹簧6的尺寸越大越容易摇摆歪斜,本发明采用上述结构,能与所述活塞杆5的支撑作用配合,减少所述塑料弹簧6摇摆歪斜,将所述塑料弹簧6的歪斜角度控制在单边1°以内。
本实施例的所述活塞杆5的下端连接有一活塞座7及用于控制所述活塞座7流体导通与否的一活塞8,即,本发明的所述应用有塑料弹簧的泵芯结构进一步包括所述活塞座7和所述活塞8,其中所述活塞8的一外圈81顶部与所述泵体10的所述泵腔11内壁面配合密封,所述活塞8的一内圈82顶部与所述活塞杆5下端配合密封。所述活塞座7具有呈倒置T形的一流道71,所述活塞座7的底部设置有位于T形的所述流道71横向部分之下的一托圈72,所述活塞8的所述内圈82套置在所述活塞座7外围且下端与所述托圈72的顶面相抵或分离。所述活塞杆5的下端设置有向外扩张的一配合套53,所述活塞8的所述内圈82的顶部边缘与所述配合套53内壁密封配合。上述结构有利于提高所述应用有塑料弹簧的泵芯结构的密封性,降低气流损失,提高所述应用有塑料弹簧的泵芯结构的效率。
所述活塞杆5下部的外周壁上设置有一凸块54,相应的,所述连接座4的所述装配口41内周壁上设置有相邻布置的供所述凸块54穿过的一缺口42及能与所述凸块54相抵限位的一凸台43。设置该结构,可通过转动所述头帽3而对所述活塞杆5的位置进行锁定,当所述活塞杆5的所述凸块54抵靠在所述凸台43上时,所述头帽3无法下压,当所述活塞杆5的所述凸块54对应所述缺口42时,所述头帽3可正常下压,从而起到避免误操作的作用。

参考本发明的说明书附图之附图5和图6,依本发明的一较佳实施例的一乳液瓶在接下来的描述中将被揭露和被阐述,其中所述乳液瓶包括一自锁乳液泵100A和一瓶体200A,所述自锁乳液泵100A被安装 于所述瓶体200A,其中所述自锁乳液泵100A被用于自所述瓶体200A泵取流体。
附图7至图20示出了所述自锁乳液泵100A的第一个具体示例,其中所述自锁乳液泵100A包括一泵体10A、一阀门20A、一取液单元30A、一锁固单元40A以及一弹簧50A。具体地,所述泵体10A具有一泵体空间11A以及分别连通于所述泵体空间11A的一进液通道12A和一顶部开口13A。所述阀门20A被构造为能够打开或封闭所述泵体10A的所述进液通道12A。所述取液单元30A包括一连接杆31A、一装配座32A和一活塞33A以及具有一流体通道34A,所述连接杆31A具有一杆体通道311A,所述装配座32A被装配于所述连接杆31A的底部,所述流体通道34A形成于所述连接杆31A和所述装配座32A之间,并且所述流体通道34A和所述杆体通道311A相连通,所述活塞33A被可上下移动地套装于所述连接杆31A的底部,其中所述取液单元30A的底部以所述活塞33A的周壁和所述泵体10A的内壁相贴合的方式被可上下活动地安装于所述泵体10A的所述泵体空间11A,并且所述自锁乳液泵100A在所述取液单元30A和所述泵体10A之间形成一泵腔60A,所述活塞33A被构造为允许或阻止所述取液单元30A的所述流体通道34A和所述泵腔60A相连通。所述锁固单元40A包括一锁定部41A和一调节部42A,所述锁定部41A位于所述泵体10A的所述泵体空间11A,并且所述锁定部41A被构造为相对于所述泵体10A的高度位置保持不变,所述调节部42A被可活动地套装于所述连接杆31A的中部和被可锁定于所述锁定部41A的不同高度位置,并且所述调节部42A被构造为限制所述连接杆31A向上运动的最大距离。所述弹簧50A的底部抵靠于所述调节部42A,所述弹簧50A的顶部抵靠于所述连接杆31A的顶部。
在所述调节部42A被锁定于所述锁定部41A的较低的位置时,所述自锁乳液泵100A处于锁定状态,此时所述取液单元30A被阻止按压,以避免所述自锁乳液泵100A被误按压而导致所述乳液瓶出现漏液问题。在所述调节部42A被锁定于所述锁定部41A的较高的位置时,所述自锁乳液泵100A处于释放状态,此时所述取液单元30A被允许按压,以自所述瓶体200A取液。
具体地,所述锁固单元40A具有一第一锁固位置和一第二锁固位置,通过改变所述调节部42A和所述锁定部41A的锁定位置的方式,所述锁固单元40A在所述第一锁固位置和所述第二锁固位置之间切换。在所述锁固单元40A处于所述第一锁固位置时,所述装配座32A的周壁贴合于所述泵体10A的内壁,参考附图5、图11和图12,此时,所述自锁乳液泵100A处于所述锁定状态,所述取液单元30A被阻止按压,以避免所述自锁乳液泵100A被误按压而导致所述乳液瓶出现漏液问题。在所述锁固单元40A处于所述第二锁固位置时,所述装配座32A的周壁远离所述泵体10A的内壁,参考附图6、图13和图14,此时,所述自锁乳液泵100A处于所述释放状态,所述取液单元30A被允许按压,以自所述瓶体200A取液。也就是说,通过改变所述调节部42A和所述锁定部41A的锁定位置的方式,所述自锁乳液泵100A在所述锁定状态和所述释放状态之间切换。
可以理解的是,继续参考附图5、图11和图12,在所述锁固单元40A处于所述第一锁固位置时,所述自锁乳液泵100A的所述泵腔60A具有最小容积或趋向于最小容积,此时,所述自锁乳液泵100A处于所述锁定状态,所述取液单元30A被阻止按压,以避免所述自锁乳液泵100A被误按压而导致所述乳液瓶出现漏液问题。参考附图6、图13和图14,在所述锁固单元40A处于所述第二锁固位置时,所述自锁乳液泵100A的所述泵腔60A具有最大容积或趋向于最大容积,此时,所述自锁乳液泵100A处于所述释放状态,所述取液单元30A被允许按压,以自所述瓶体200A取液。
现在转到附图11和图12,并结合附图5,处于所述第一锁固位置的所述锁固单元40A使得所述取液单元30A被阻止按压,如此无论是在运输所述乳液瓶时,还是在携带所述乳液瓶时,即便是在所述取液单元30A受力,位于所述自锁乳液泵100A的所述泵腔60A和所述瓶体200A内的流体也不会经所述取液单元30A的所述流体通道34A和所述连接杆31A的所述杆体通道311A排出。处于所述第一锁固位置的 所述锁固单元40A使得所述取液单元30A的所述装配座32A的周壁可靠地贴合于所述泵体10A的内壁,从而无论是在运输所述乳液瓶时,还是在携带所述乳液瓶时,即便是所述乳液瓶倾倒,位于所述自锁乳液泵100A的所述泵腔60A和所述瓶体200A内的流体也不会经所述取液单元30A的所述流体通道34A和所述连接杆31A的所述杆体通道311A排出。处于所述第一锁固位置的所述锁固单元40A使得所述自锁乳液泵100A的高度尺寸减小,以降低所述乳液瓶的高度尺寸,从而减小所述乳液瓶所占用的空间,这样,有利于降低所述乳液瓶的存储成本和运输成本。所述弹簧50A位于所述连接杆31A的顶部和所述锁固单元40A的所述调节部42A之间,从而在所述锁固单元40A处于所述第一锁固位置时,所述自锁乳液泵100A能够避免所述弹簧50A被过分压缩,以保证所述弹簧50A的弹性而提高所述自锁乳液泵100A的可靠性。
特别地,通过设置所述弹簧50A于所述连接杆31A的顶部和所述调节部42A之间以在所述锁固单元40A处于所述第一锁固位置时避免所述弹簧50A被过分压缩的方式对塑料材质的所述弹簧50A来说是特别重要的。换言之,在本发明的一些具体示例中,所述弹簧50A是塑料弹簧,本发明将在后续进一步揭露塑料材质的所述弹簧50A的具体结构。
现在转到附图13和图14,并结合附图6,处于所述第二锁固位置的所述锁固单元40A使得所述取液单元30A被允许按压,在向下按压所述取液单元30A时,所述自锁乳液泵100A的所述泵腔60A被压缩,并且所述活塞33A允许所述取液单元30A的所述流体通道34A和所述自锁乳液泵100A的所述泵腔60A相连通,以允许位于所述自锁乳液泵100A的所述泵腔60A的流体经所述取液单元30A的所述流体通道34A和所述连接杆31A的所述杆体通道311A排出。可以理解的是,在向下按压所述取液单元30A时,所述弹簧50A被所述连接杆31A朝向靠近所述调节部42A的方向压缩而产生弹性形变,供积蓄弹性势能,在撤销施加于所述取液单元30A的压力时,所述弹簧50A在恢复初始状态的过程中向上推动所述连接杆31A,以使所述连接杆31A恢复初始位置。
继续参考附图7至图20,并结合附图5和图6,所述阀门20A进一步包括一个阀片21A、环绕于所述阀片21A的一个安装环22A以及一体地连接所述阀片21A和所述安装环22A的至少一个可变形的连接臂23A,其中所述安装环22A被固定地安装于所述泵体10A的所述泵体空间11A,并由所述连接臂23A悬持所述阀片21A于封闭所述泵体10A的所述进液通道12A的位置。可以理解的是,在所述阀片21A向上运动而打开所述泵体10A的所述进液通道12A时,所述阀片21A向上拉动所述连接臂23A,使所述连接臂23A在高度方向产生变形而积蓄弹性势能,以在后续由所述连接臂23A将所述阀片21A拉回至关闭所述泵体10A的所述进液通道12A的位置。
在本本发明的所述自锁乳液泵100A的这个具体示例中,所述连接臂23A在所述阀片21A和所述安装环22A之间具有至少一个弯折,以在所述阀片21A向上运动时允许所述阀片21A拉动所述连接臂23A在高度方向产生变形,增加所述阀片21A的行程。具体地,所述连接臂23A的一个端部连接到所述阀片21A的一侧,所述连接臂23A的另一个端部连接到所述安装环22A的非对应侧,以使所述连接臂23A在所述阀片21A和所述安装环22A之间具有至少一个弯折,供增加所述阀片21A在高度方向的行程。
值得一提的是,所述阀门20A的所述连接臂23A的数量在本发明的所述自锁乳液泵100A中不受限制。例如,在附图7至图20示出的本发明的所述自锁乳液泵100A的这个具体示例中,所述阀门20A包括三个所述连接臂23A,三个所述连接臂23A呈中心对称地分布于所述阀片21A和所述安装环22A之间。

可选地,在本发明的所述自锁乳液泵100A的其他示例中,所述阀门20A可以是球阀,其通过整体向上运动的方式打开所述泵体10A的所述进液通道12A。
继续参考附图7至图20,并结合附图5和图6,所述取液单元30A进一步包括一头帽35A,所述头帽35A具有一头帽通道351A,其中所述头帽35A被安装于所述连接杆31A的顶部,并且所述头帽35A的所述头帽通道351A和所述连接杆31A的所述杆体通道311A相连通,如此在向下按压所述取液单元30A时,位于所述自锁乳液泵100A的所述泵腔60A的流体经所述取液单元30A的所述流体通道34A、所述连接杆31A的所述杆体通道311A和所述头帽35A的所述头帽通道351A排出。

优选地,所述延伸腿51A的所述牵引部514A的厚度尺寸小于所述腿部513A的厚度尺寸,从而在保证所述牵引部514A具有限制所述弹簧50A的变形方向的情况下,不仅能够节省材料来降低所述弹簧50A的制造成本,而且在按压所述取液单元30A的所述头帽35A时能够减少所述牵引部514A提供的阻力,以便于用户顺畅地按压所述取液单元30A。优选地,所述延伸腿51A在两个所述腿部513A和相邻两个所述牵引部514A之间形成的所述镂空部分510A是平行四边形结构,从而在用户按压所述取液单元30A时,所述弹簧50A能够被顺畅地挤压变形。
继续参考附图9和图10,所述弹簧50A的相邻所述延伸腿51A的所述顶部连接部511A是一体式的,并且这些所述延伸腿51A的所述顶部连接部511A形成圆环结构,相邻所述延伸腿51A的所述底部连接部512A是一体式的,并且这些所述延伸腿51A的所述底部连接部512A形成圆环结构,这样,所述弹簧50A能够被稳定地设置于所述连接杆31A和所述调节部42A之间,以避免所述弹簧50A横向移位。
继续参考附图7至图20,并结合附图5和图6,在本发明的所述自锁乳液泵100A的这个具体示例中,所述锁定部41A被固定地安装于所述泵体10A,通过驱动所述调节部42A产生相对于所述锁定部41A转动的方式,所述锁固单元40A可以在所述第一锁固位置和所述第二锁固位置之间切换,相应地,所述自锁乳液泵100A可以在所述锁定状态和所述释放状态之间切换。可选地,在本发明的所述自锁乳液泵100A的其他示例中,所述锁定部41A被固定地安装于所述泵体10A,通过驱动所述调节部42A沿高度方向产生相对于所述锁定部41A滑动的方式,所述锁固单元40A可以在所述第一锁固位置和所述第二锁固位置之间切换。

继续参考附图34、图36和图38,所述控流元件72’分隔所述取液壳71’的所述壳体空间711’为相独立的一上部空间7111’和一下部空间7112’,所述取液壳71’的所述顶部出液孔712’和所述侧部进液孔713’均连通于所述上部空间7111’,所述支撑柱73’位于所述下部空间7112’,通过这样的方式,一方面,在按压所述头帽20’时,所述喷雾泵1000’的所述泵腔80’内的流体自所述取液壳71’的所述侧部进液孔713’进入所述上部空间7111’后能够快速地推动所述控流元件72’向下移动,以允许所述上部空间7111’和所述顶部出液孔712’相连通而提高所述喷雾泵1000’的灵敏度,另一方面,进入所述上部空间7111’的流体被阻止进入所述下部空间7112’,以避免对位于所述下部空间7112’的所述支撑柱73’的回弹能力产生不良影响。也就是说,所述支撑柱73’始终不与流体接触。
具体地,参考附图34至图39,所述控流元件72’进一步包括一控流座721’、一控流柱722’以及一控流环723’,所述控流柱722’自所述控流座721’的中部一体地向上延伸,所述控流柱722’用于允许或阻止所述取液壳71’的所述上部空间7111’和所述顶部出液孔712’相连通,所述控流环723’自所述控流座721’的边缘一体地向上和向外延伸,所述控流环723’被压缩地抵靠于所述取液壳71’的内壁,如此所述控流元 件72’分隔所述取液壳71’的所述壳体空间711’为相独立的所述上部空间7111’和所述下部空间7112’。
在本发明的所述喷雾泵1000’中,所述控流元件72’以所述控流环723’被所述取液壳71’的内壁压缩的方式被可上下移动地设置于所述取液壳71’的所述壳体空间711’,通过这样的方式,一方面,所述取液部70’避免在所述控流元件72’和所述取液壳71’的连接位置产生缝隙,这样,经所述取液壳71’的所述侧部进液孔713’进入所述上部空间7111’的流体被阻止进入所述下部空间7112’,以避免对位于所述下部空间7112’的所述支撑柱73’的回弹能力产生不良影响,另一方面,所述取液部70’增加所述控流元件72’和所述取液壳71’的相对位置的稳定性,避免所述控流元件72’在所述取液壳71’的所述壳体空间711’内倾斜。
值得一提的是,所述控流元件72’的所述控流柱722’阻止所述取液壳71’的所述上部空间7111’和所述顶部出液孔712’相连通的方式在本发明的所述喷雾泵1000’中不受限制。例如,在本发明的所述喷雾泵1000’的这个具体示例中,参考附图34至图39,所述控流元件72’2的所述控流柱722’的顶部伸入所述取液壳71’的所述顶部出液孔712’,且所述控流柱722’的周壁和所述取液壳71’的用于形成所述顶部出液孔712’的内壁紧密贴合,以使得所述控流元件72’的所述控流柱722’能够阻止所述取液壳71’的所述上部空间7111’和所述顶部出液孔712’相连通。可以理解的是,在所述控流元件72’2的所述控流柱722’移离所述取液壳71’的所述顶部出液孔712’后,所述控流元件72’的所述控流柱722’允许所述取液壳71’的所述上部空间7111’和所述顶部出液孔712’相连通。
继续参考附图34至图39,所述取液壳71’进一步包括一上壳体714’和一下壳体715’,所述上壳体714’和所述下壳体715’被相互安装,以在所述上壳体714’和所述下壳体715’之间形成所述壳体空间711’,所述顶部出液孔712’和所述侧部进液孔713’均形成于所述上壳体714’。通过将所述取液壳71’区分为所述上壳体714’和所述下壳体715’的方式,便于组装所述取液部70’。
值得一提的是,所述取液壳71’的所述上壳体714’和所述下壳体715’的安装方式在本发明的所述喷雾泵1000’中不受限制。例如,在本发明的所述喷雾泵1000’的这个具体示例中,参考附图34至图39,所述下壳体715’的一部分被嵌装于所述上壳体714’,基于所述下壳体715’的外壁和所述上壳体714’的内壁之间产生的摩擦力,所述上壳体714’和所述下壳体715’被可靠地安装,并且所述上壳体714’和所述下壳体715’的结合位置没有间隙,以避免所述喷雾泵1000’的所述泵腔80’内的流体经所述上壳体714’和所述下壳体715’的结合位置进入所述取液壳71’的所述下部空间7112’。
优选地,所述下壳体715’环绕于所述支撑柱73’的底部,以使得所述支撑柱73’能够被可靠地保持在所述下壳体715’和所述控流元件72’之间。具体地,所述下壳体715’具有一安装槽7151’,所述支撑柱73’的底部被安装于所述下壳体715’的所述安装槽7151’,以使得所述下壳体715’环绕于所述支撑柱73’的底部,当所述控流元件72’被驱动向下运动而压缩所述支撑柱73’时,所述下壳体715’能够避免变形后的所述支撑柱73’产生倾斜,从而使得所述支撑柱73’被可靠地保持在所述下壳体715’和所述控流元件72’之间。
在本发明的所述喷雾泵1000’中,参考附图37,所述取液壳71’的所述上壳体714’的内壁是倾斜内壁,其顶部与所述取液壳71’的中心轴线之间的距离D1小于底部与所述取液壳71’的中心轴线之间的距离D2,如此所述控流元件72’的所述控流环723’在所述取液部70’处于所述关闭状态时所受到的压缩力所大于所述取液部70’处于所述打开状态时所受到的压缩力,即,所述控流元件72’越往下运动,所述控流元件72’的所述控流环723’所受到的压缩力越小。通过上述这种结构设计,自所述取液壳71’的所述侧部进液孔713’进入所述上部空间7111’的流体能够轻松地推动所述控流元件72’向下运动,以使所述取液部70’自所述关闭状态切换至所述打开状态。
继续参考附图33至图39,所述支撑柱73’具有一柱体穿孔731’,所述取液壳71’的所述下壳体715’封闭所述支撑柱73’的底部开口,所述控流元件72’封闭所述支撑柱73’的顶部开口,这样,在按压所述头 帽20’时,所述控流元件72’被进入所述取液壳71’的所述上部空间7111’的流体驱动向下运动,以压缩所述支撑柱73’使其产生变形而积蓄弹性势能,同时,位于所述支撑柱73’的所述柱体穿孔731’的空气被压缩,在撤销施加于所述头帽20’的压力时,所述支撑柱73’和位于所述支撑柱73’的所述柱体穿孔731’的空气提供复合的回复力,以驱动所述控流元件72’可靠且及时地复位而阻止所述取液壳71’的所述上部空间7111’和所述顶部出液孔712’相连通。
优选地,所述下壳体715’具有一凹槽7152’,所述凹槽7152’连通于所述支撑柱73’的所述柱体穿孔731’,这样,在按压所述头帽20’而使所述控流元件72’被进入所述取液壳71’的所述上部空间7111’的流体驱动向下运动时,位于所述支撑柱73’的所述柱体穿孔731’内的空气和位于所述下壳体715’的所述凹槽7152’内的空气均能够被压缩,从而在撤销施加于所述头帽20’的压力后,所述支撑柱73’和被压缩的空气能够提供足够的回复力,供驱动所述控流元件72’可靠且及时地复位。
继续参考附图32至图39,所述头帽20’进一步包括一头帽主体22’、一头帽安装柱23’和一头帽延伸环24’以及具有一头帽槽25’,所述头帽安装柱23’自所述头帽主体22’的中部一体地向下延伸,所述头帽通道21’形成于所述头帽主体22’和所述头帽安装柱23’,所述头帽延伸环24’自所述头帽主体22’的边缘一体地向下延伸,并且所述头帽延伸环24’环绕于所述头帽安装柱23’的外侧,以在所述头帽安装柱23’和所述头帽延伸环24’之间形成所述头帽槽25’,其中所述雾化喷嘴30’被安装于所述头帽主体22’,所述活塞40’的所述连杆43’的顶部被安装于所述头帽安装柱23’,其中所述弹簧60’被套装于所述活塞40’的所述连杆43’和所述头帽20’的所述头帽安装柱23’,所述弹簧60’的顶部向上延伸至所述头帽20’的所述头帽槽25’并抵靠于所述头帽主体22’,所述弹簧60’的底部向下延伸至所述泵体10’的所述泵体空间11’并抵靠于所述弹簧座90’。
继续参考附图32至图39,所述喷雾泵1000’进一步包括一装配部100’,所述装配部100’包括一装配肩101’和自所述装配肩101’一体地向下延伸的一螺牙102’,所述装配肩101’具有一肩穿孔1011’,所述泵体10’的顶部被装配于时所述装配肩101’,所述弹簧60’和所述活塞40’的所述连杆43’经所述装配肩101’的所述肩穿孔1011’延伸至所述装配肩101’的上方,其中所述装配部100’的所述螺牙102’能够被螺装于所述包装容器2000’的容器口,以实现所述喷雾泵1000’和所述包装容器2000’的可靠安装。优选地,所述装配部100’进一步包括一遮挡环103’,所述遮挡环103’自所述装配肩101’一体地向上延伸,所述头帽20’的所述头帽延伸环24’向下延伸至所述装配部100’的所述遮挡环103’的内侧,以由所述遮挡环103’遮挡所述泵体10’和所述头帽延伸环24’之间的间隙,从而使得所述泵体10’和所述头帽延伸环24’之间的间隙以及所述弹簧60’视觉上不可见。
优选地,在本发明的所述喷雾泵1000’中,所述泵体10’、所述头帽20’、所述雾化喷嘴30’、所述活塞40’、所述阀门50’、所述弹簧60’、所述弹簧座90’、所述装配部100’以及所述取液部70’的所述取液壳71’、所述控流元件72’和所述支撑柱73’均是塑料材质,以使得所述喷雾泵1000’整体上可回收,从而降低所述喷雾泵1000’的回收难度。
也就是说,在本发明的所述喷雾泵1000’的一些实施例中,所述弹簧60’是塑料弹簧60a’,参考附图40和图41,所述塑料弹簧60a’进一步包括至少三延伸腿61’,每个所述延伸腿61’分别绕所述塑料弹簧60a’的中心轴线呈螺旋状地延伸,每个所述延伸腿61’分别具有多个四边形的镂空部分610’,这些所述镂空部分610’分别沿着所述延伸腿61’的高度方向相互间隔地分布,相邻所述延伸腿61’的侧部是一体式的,通过这样的方式,一方面,在所述塑料弹簧60a’被压缩时,这些所述延伸腿61’能够均衡受力,以避免所述塑料弹簧60a’倾斜,再一方面,所述塑料弹簧60a’的整个高度方向均能够被压缩,以有利于增大所述塑料弹簧60a’的形变量,又一方面,所述塑料弹簧60a’在被压缩时能够阻止这些所述延伸腿61’向四周膨大, 即,所述塑料弹簧60a’的变形方向被限制在高度方向,以避免被压缩的所述塑料弹簧60a’剐蹭所述泵体10’和/或所述头帽20’的内壁,从而保证用户在按压所述头帽20’时的手感和顺畅性,并且避免被压缩的所述塑料弹簧60a’被所述泵体10’和/或所述头帽20’的内壁卡住而导致失效问题,从而提高所述喷雾泵1000’的可靠性。
继续参考附图40和图41,所述塑料弹簧60a’的每个所述延伸腿61’分别包括一顶部连接部611’、一底部连接部612’、两腿部613’以及多个牵引部614’,两个所述腿部613’被相互间隔地设置,所述顶部连接部611’的相对两端分别延伸至和被连接于两个所述腿部613’的顶部,所述底部连接部612’的相对两端分别延伸至和被连接于两个所述腿部613’的底部,这些所述牵引部614’的相对两端分别延伸至和被连接于两个所述腿部613’的中部的不同位置,以在相邻两个所述牵引部614’和两个所述腿部613’之间形成所述镂空部分610’,在这些所述牵引部614’的最上部的一个所述牵引部614’、所述顶部连接部611’和两个所述腿部613’之间形成所述镂空部分610’,在这些所述牵引部614’的最下部的一个所述牵引部614’、所述底部连接部612’和两个所述腿部613’之间形成所述镂空部分610’,其中一个所述延伸腿61’的一个所述腿部613’和相邻所述延伸腿61’的一个所述腿部613’是一体式的,这样,所述塑料弹簧60a’的每个所述延伸腿61’分别具有沿高度方向间隔分布的多个四边形的所述镂空部分610’,使得所述塑料弹簧60a’的整个高度方向均能够被压缩,以有利于增大所述塑料弹簧60a’的形变量。在所述塑料弹簧60a’被压缩时,所述延伸腿61’的这些所述牵引部614’能够牵引两个所述腿部613’,以将所述腿部613’的变形方向限制在所述塑料弹簧60a’的高度方向,从而阻止所述腿部613’向侧方变形,进而阻止所述塑料弹簧60a’向四周膨大。
优选地,所述延伸腿61’的所述牵引部614’的厚度尺寸小于所述腿部613’的厚度尺寸,从而在保证所述牵引部614’具有限制所述塑料弹簧60a’的变形方向的情况下,不仅能够节省材料来降低所述塑料弹簧60a’的制造成本,而且在按压所述头帽20’时能够减少所述牵引部614’提供的阻力,以便于用户顺畅地按压所述头帽20’。

再次转到附图56和图57,在本发明的所述乳液泵100”的这个具体示例中,所述活塞22”的所述活塞外环222”的外壁紧密地贴合于所述泵体10”的内壁,以在所述活塞22”的所述活塞外环222”的外壁和所述泵体10”的内壁之间产生足够的摩擦力,从而在通过所述乳液泵100”泵取被盛装于所述盛装容器200”的乳液时,避免乳液经所述泵体10”和所述活塞22”的结合位置外溢,以提高所述乳液泵100”的可靠性。
值得一提的是,所述弹簧座40”将所述取液单元20”锁装于所述泵体10”的所述泵体空间11”的方式在本发明的所述乳液泵100”中不受限制。例如,在本发明的所述乳液泵100”的这个具体示例中,参考附图56和图57,所述弹簧座40”具有一个座体穿孔41”,所述驱动杆24”包括一个驱动环242”和自所述驱动环242”一体地向上延伸的一个连接管243”,所述驱动环242”的外径尺寸大于所述弹簧座40”的所述座体穿孔41”的内径尺寸,所述连接管243”的外径尺寸小于所述弹簧座40”的所述座体穿孔41”的内径尺寸,所述连接管243”伸入所述弹簧座40”的所述座体穿孔41”,以套装所述弹簧座40”于所述驱动杆24”的中部,其中所述弹簧座40”的外径尺寸和形状匹配于所述泵体10”的内壁的尺寸和形状,在所述弹簧座40”自所述泵体10”的所述顶部开口13”被塞入所述泵体10”的所述泵体空间11”后,基于产生于所述弹簧座40”的外壁和所述泵体10”的内壁之间的摩擦力,所述弹簧座40”被固定地安装于所述泵体10”的所述泵体空间11”,如此所述弹簧座40”锁装所述取液单元20”于所述泵体10”的所述泵体空间11”。可以理解的是,由于所述驱动杆24”的所述驱动环242”的外径尺寸大于所述弹簧座40”的所述座体穿孔41”的内径尺寸,从而所述弹簧座40”能够阻止所述取液单元20”向上脱离所述泵体10”的所述泵体空间11”,以提高所述乳液泵100”的可靠性。
接着参考附图56和图57,在本发明的所述乳液泵100”的这个具体示例中,所述塑料弹簧50”的顶部套装于所述头帽21”的所述头帽安装部212”并抵靠于所述头帽延伸嘴213”,所述塑料弹簧50”的底部套装于所述驱动杆24”的所述连接管243”并抵靠于所述弹簧座40”,如此所述塑料弹簧50”能够被可靠地设置于所述取液单元20”和所述弹簧座40”之间,并且所述头帽21”的所述头帽安装部212”和所述驱动杆24”的所述连接管243”相互配合阻止所述塑料弹簧50”偏斜。
继续参考附图56和图57,所述头帽21”进一步包括一个罩环214”和具有一个收容腔215,所述罩环214”自所述头帽延伸嘴213”一体地向下延伸,并且所述罩环214”环绕于所述头帽安装部212”的外部,以在所述头帽安装部212”和所述罩环214”之间形成所述收容腔215,其中所述塑料弹簧50”的顶部被可压缩地设置于所述头帽21”的所述收容腔215。优选地,所述头帽21”的所述罩环214”经所述泵体10”的所述顶部开口13”延伸至所述泵体10”的所述泵体空间11”,如此所述泵体10”和所述头帽21”的所述罩环214”相互配合,供隐藏所述塑料弹簧50”。
继续参考附图52至图70,所述乳液泵100”进一步包括一个瓶盖60”,所述瓶盖60”以所述瓶盖60”环绕于所述泵体10”的顶部的方式被固定地安装于所述泵体10”。在所述泵体10”的底部经所述盛装容器200”的容器口被塞入所述盛装容器200”后,所述瓶盖60”能够被固定地安装于所述盛装容器200”,以供安装所述乳液泵100”于所述盛装容器200”。例如,所述瓶盖60”的内壁和所述盛装容器200”的容器口的外壁分别设有螺纹结构,两者相互配合,以固定地安装所述瓶盖60”于所述盛装容器200”,从而安装所述乳液泵100”于所述盛装容器200”。
值得一提的是,所述瓶盖60”被固定地安装于所述泵体10”的顶部的方式在本发明的所述乳液泵100”中不受限制。例如,在本发明的所述乳液泵100”的这个具体示例中,参考附图56和图57,所述瓶盖60”具有一个盖体穿孔61”和一个环形的卡装槽62”,所述泵体10”的顶部被卡装于所述瓶盖60”的所述卡装槽62”,以固定地安装所述瓶盖60”于所述盛装容器200”,其中所述头帽21”的所述罩环214”的底部依次经所述瓶盖60”的所述盖体穿孔61”和所述泵体10”的所述顶部开口13”延伸至所述泵体10”的所述泵体空间11”。优选地,所述瓶盖60”的所述盖体穿孔61”的内径尺寸大于所述头帽21”的所述罩环214”的外径尺寸,以在所述瓶盖60”和所述头帽21”的所述罩环214”之间具有间隙,从而在所述头帽21”被按压向下运动时,避免所述头帽21”的所述罩环214”的外壁和所述瓶盖60”的内壁产生摩擦。
优选地,所述乳液泵100”进一步包括一个密封环70”,在所述瓶盖60”被固定地安装于所述盛装容器200”时,所述密封环70”被设置于所述泵体10”的顶部和所述盛装容器200”之间,以起到密封所述泵体10”和所述盛装容器200”的结合位置的作用。
优选地,所述乳液泵100”进一步包括一个延伸管80”,所述延伸管80”具有一个管体通道81”,所述延伸管80”的顶部被固定地安装于所述泵体10”的底部,并且所述延伸管80”的所述管体通道81”能够通过所述泵体10”的所述进液通道12”连通于所述泵体10”的所述泵体空间11”。在所述乳液泵100”被安装于所述盛装容器200”时,所述延伸管80”的底部能够朝向所述盛装容器200”的底部延伸,以允许所述乳液泵100”泵取处于所述盛装容器200”的底部的乳液。
现在转动附图58至图65,并结合附图54至图57、图66至图70,所述塑料弹簧50”包括一个上环体51”、一个下环体52”、一个牵引部53”以及至少三个弹性腿54”,所述牵引部53”和这些所述弹性腿54”分别绕着所述塑料弹簧50”的中心轴线呈螺旋状地延伸,其中这些所述弹性腿54”的一个端部分别向上延伸至和被连接于所述上环体51”,另一个端部分别向下延伸至和被连接于所述下环体52”,其中所述牵引部53”的一个端部向上延伸至和被连接于所述弹性腿54”,另一个端部向下延伸至和被连接于所述弹性腿54”,并且所述牵引部53”和每个所述弹性腿54”分别具有多个连接位置。在所述塑料弹簧50”被组装于所 述乳液泵100”的所述取液单元20”和所述弹簧座40”之间时,所述塑料弹簧50”的所述上环体51”抵靠于所述取液单元20”的所述头帽21”的所述头帽延伸嘴213”,所述塑料弹簧50”的所述下环体52”抵靠于所述弹簧座40”,所述塑料弹簧50”的所述牵引部53”和这些所述弹性腿54”环绕于所述驱动杆24”的所述连接管243”和所述头帽21”的所述头帽安装部212”的外部。
在所述塑料弹簧50”被挤压时,所述牵引部53”能够牵引这些所述弹性腿54”,以将这些所述弹性腿54”的变形方向限制在所述塑料弹簧50”的高度方向,从而阻止这些所述弹性腿54”向所述塑料弹簧50”的四周膨大,参考附图65,通过这样的方式,被挤压的所述塑料弹簧50”能够避免剐蹭所述头帽21”的所述罩环214”的内壁和剐蹭所述泵体10”的内壁,如此不仅能够提高用户在按压所述头帽21”时的手感和顺畅性,而且能够避免因所述塑料弹簧50”的这些所述弹性腿54”被所述头帽21”的所述罩环214”的内壁和/或所述泵体10”的内壁卡住导致的失效问题。
所述塑料弹簧50”的这些所述弹性腿54”分别绕着所述塑料弹簧50”的中心轴线呈螺旋状地延伸,从而在所述塑料弹簧50”被挤压时,在不需要所述牵引部53”辅助的情况下,这些所述弹性腿54”即可使所述塑料弹簧50”的周向方向(周向方向是指环绕于所述塑料弹簧50”的中心轴线的方向,轴向方向和高度方向垂直)均衡受力,因此在本发明中,所述塑料弹簧50”不要求所述牵引部53”直接连接所述上环体51”和所述下环体52”,如此有利于通过节省材料的方式降低成本和根据需要灵活地设计所述塑料弹簧50”的所述弹性腿54”和所述牵引部53”的结构关系。
所述牵引部53”的顶部被连接于一个所述弹性腿54”,其未被连接于所述上环体51”,这样,所述塑料弹簧50”能够避免所述牵引部53”、所述弹性腿54”和所述上环体51”之间形成三角形结构,相应地,所述牵引部53”的底部被连接于一个所述弹性腿54”,其未被连接于所述下环体52”,这样,所述塑料弹簧50”能够避免所述牵引部53”、所述弹性腿54”和所述下环体52”之间形成三角形结构,通过这样的方式,所述塑料弹簧50”的整个高度位置均可以被压缩,以有利于增大所述塑料弹簧50”的形变量。
可以理解的是,所述塑料弹簧50”在被挤压时,所述上环体51”和所述下环体52”相互配合均衡地压缩所述牵引部53”和这些所述弹性腿54”,以使所述牵引部53”和这些所述弹性腿54”均产生形变而积蓄弹性势能,在这个过程中,所述牵引部53”对这些所述弹性腿54”进行牵引,以阻止这些所述弹性腿54”向四周膨大而将所述弹性腿54”的变形方向限制在所述塑料弹簧50”的高度方向。在施加于所述塑料弹簧50”的外力撤销时,所述弹性腿54”在恢复初始状态的过程中提供主要的回复力,供驱使所述塑料弹簧50”恢复至初始状态,在这个过程中,所述牵引部53”提供辅助的回复力,供辅助驱使所述塑料弹簧50”回复至初始状态。可见,在本发明的所述乳液泵100”中,所述塑料弹簧50”的所述牵引部53”的主要作用是在所述塑料弹簧50”被挤压时牵引这些所述弹性腿54”以阻止这些所述弹性腿54”向四周膨大,次要作用是在挤压所述塑料弹簧50”的外力撤销后提供辅助的回复力。
基于所述牵引部53”在本发明的所述塑料弹簧50”中的作用,在本发明的一些实施例中,所述牵引部53”的厚度尺寸可以被设计为小于所述弹性腿54”的厚度尺寸,在保证所述牵引部53”具有限制这些所述弹性腿54”的变形方向和提供辅助的回复力的作用的情况下,不仅能够节省材料来降低所述塑料弹簧50”的成本,而且在按压所述头帽21”时能够减少所述牵引部53”提供的阻力,以便于用户顺畅地按压所述头帽21”。在本发明的另一些实施例中,所述牵引部53”的宽度尺寸可以小于所述弹性腿54”的宽度尺寸,这样,在保证所述牵引部53”具有限制这些所述弹性腿54”的变形方向和提供辅助的回复力的作用的情况下,不仅能够节省材料来降低所述塑料弹簧50”的成本,而且相对于所述弹性腿54”的外壁来说,所述牵引部53”的外壁可以被内缩,即,所述弹性腿54”的外壁和所述塑料弹簧50”的中心轴线之间的距离大于所述牵引部53”的外壁和所述塑料弹簧50”之间的距离。可选地,在本发明的其他示例中,所述弹性腿54”的外壁 和所述塑料弹簧50”的中心轴线之间的距离可以等于所述牵引部53”的外壁和所述塑料弹簧50”之间的距离。
在本发明中,所述塑料弹簧50”的所述牵引部53”的延伸方向和所述弹性腿54”的延伸方向相反,以在所述牵引部53”可靠地提供辅助的回复力的作用的同时,尽可能地减小所述牵引部53”的厚度尺寸。例如,在一些实施例中,所述弹性腿54”绕所述塑料弹簧50”的中心轴线沿逆时针方向螺旋地延伸,所述牵引部53”绕所述塑料弹簧50”的中心轴线沿顺时针方向螺旋地延伸,在另一些实施例中,所述弹性腿54”绕所述塑料弹簧50”的中心轴线沿顺时针方向螺旋地延伸,所述牵引部53”绕所述塑料弹簧50”的中心轴线沿逆时针方向螺旋地延伸,通过这样的方式,在所述塑料弹簧50”被挤压时,一方面,所述牵引部53”能够牵引这些所述弹性腿54”,以将这些所述弹性腿54”的变形方向限制在所述塑料弹簧50”的高度方向而阻止这些所述弹性腿54”向四周膨大,另一方面,所述牵引部53”沿高度方向被压缩,从而在撤销施加于所述塑料弹簧50”的压力后,所述牵引部53”能够提供辅助的回复力,供所述塑料弹簧50”恢复初始状态,再一方面,所述牵引部53”的厚度尺寸可以被进一步降低,这样不仅可以节省材料,而且能够增大所述塑料弹簧50”的形变量。具体而言,由于所述牵引部53”的厚度尺寸可以更薄,所述塑料弹簧50”在被压缩后,相邻所述弹性腿54”在高度方向的距离可以更近,从而增大所述塑料弹簧50”的形变量。
继续参考附图58至图65,所述牵引部53”包括多个牵引段531”,所述牵引段531”的一个端部延伸至和被连接于相邻两个所述弹性腿54”中的一个所述弹性腿54”,另一个端部延伸至和被连接于相邻两个所述弹性腿54”中的另一个所述弹性腿54”,并且所述上环体51”不与最上方的所述牵引段531”连接,这样,所述塑料弹簧50”能够避免在所述上环体51”、所述弹性腿54”和最上方的所述牵引段531”之间形成三角形结构,以在所述塑料弹簧50”被挤压时使得所述上环体51”和最上方的所述牵引段531”之间的距离能够减小,相应地,所述下环体52”不与最下方的所述牵引段531”连接,这样,所述塑料弹簧50”能够避免在所述下环体52”、所述弹性腿54”和最下方的所述牵引段531”之间形成三角形结构,以在所述塑料弹簧50”被挤压时使得所述下环体52”和最下方的所述牵引段531”之间的距离能够减小。也就是说,所述塑料弹簧50”的整个高度位置均可以被压缩,以有利于增大所述塑料弹簧50”的形变量。
参考附图58和图65,从侧视视角来看,所述牵引段531”倾斜地延伸于相邻所述弹性腿54”之间,例如,所述牵引段531”的延伸方向和所述弹性腿54”的延伸方向相反,如此在所述塑料弹簧50”被挤压时,所述牵引段531”不仅可以牵引这些所述弹性腿54”以阻止这些所述弹性腿54”向四周膨大,而且在挤压所述塑料弹簧50”的外力撤销后提供辅助的回复力。另外,从俯视视角来看,所述牵引段531”呈弧状地延伸于相邻两个所述弹性腿54”之间,以使所述牵引段531”的形状匹配所述塑料弹簧50”的整体形状,从而便于将所述塑料弹簧50”套装于所述驱动杆24”的所述连接管243”和所述头帽21”的所述头帽安装部212”。
接着,参考附图58、图59、图62和图65,在本发明中,相邻两个所述弹性腿54”和被连接于这两个所述弹性腿54”的相邻两个所述牵引段531”之间形成平行四边形结构,从而在用户按压所述头帽21”时,所述塑料弹簧50”能够被顺畅地挤压变形。
接着,参考附图58、图59、图62和图65,在本发明中,任意一个所述弹性腿54”和被连接于这个所述弹性腿54”的沿高度方向相邻的两个所述牵引段531”之间形成“Z”字形结构,这样,在所述塑料弹簧50”被挤压时,这些所述牵引段531”能够在所述弹性腿54”的不同的高度位置提供一致的牵引力,以将所述弹性腿54”的变形方向限制在所述塑料弹簧50”的高度方向,阻止所述塑料弹簧50”向四周膨大。
接着,参考附图58、图59、图62和图65,在本发明中,任意一个所述弹性腿54”和被连接于这个所述弹性腿54”的沿水平方向相邻的两个所述牵引段531”之间形成“X”字形结构,这样,在施加于所述塑料弹簧50”的外力撤销时,所述弹性腿54”和所述牵引段531”能够相互配合以保证使所述塑料弹簧50”回 复至初始状态。
附图66至图70示出了所述乳液泵100”泵取被盛装于所述盛装容器200”的乳液的过程。
参考附图66和图67,在开始按压所述头帽21”时,一方面,所述头帽21”通过所述驱动杆24”驱动所述活塞座23”向下运动,此时所述活塞22”的顶部贴合所述驱动杆24”的底部并避免在所述活塞22”和所述驱动杆24”的底部之间形成间隙,所述活塞22”的底部远离所述活塞座23”的所述座体231”并允许所述泵体10”的所述泵体空间11”和所述活塞座23”的所述导液管232”的所述进液孔2322”相连通,另一方面,所述头帽21”朝向所述弹簧座40”的方向挤压所述塑料弹簧50”。
参考附图68,在所述头帽21”被进一步按压时,所述驱动杆24”推动所述活塞22”向下运动,以减小所述泵体10”的所述泵体空间11”的体积,从而使处于所述泵体10”的所述泵体空间11”的乳液依次经所述导液管232”的所述进液孔2322”、所述导液孔2321”、所述驱动杆24”的所述杆体通道241”和所述头帽21”的所述头帽通道211”排出。在这个过程中,所述阀门30”始终你保持在关闭所述泵体10”的所述进液通道12”的位置,所述塑料弹簧50”的所述牵引段531”牵引相邻所述弹性腿54”,以将相邻所述弹性腿54”的变形方向限制在高度方向而阻止所述塑料弹簧50”向四周膨大,这样,不仅能够提高用户在按压所述头帽21”时的手感和顺畅性,而且能够避免因所述塑料弹簧50”的这些所述弹性腿54”被所述头帽21”的所述罩环214”的内壁和/或所述泵体10”的内壁卡住导致的失效问题。
参考附图69和图70,在按压所述头帽21”的外力撤销后,所述弹性腿54”在恢复初始状态时提供主要的回复力和所述牵引段531”在恢复初始状态时提供次要的回复力,以驱使所述塑料弹簧50”恢复初始状态而驱动所述头帽21”带动所述驱动杆24”、所述活塞座23”和所述活塞22”复位,在这个过程中,所述阀门30”打开所述泵体10”的所述进液通道12”以允许被盛装于所述盛装容器200”的乳液被泵入所述泵体10”的所述泵体空间11”,并在所述泵体10”的所述泵体空间11”的压力和所述盛装容器200”的压力保持一致时,所述阀门30”恢复至关闭所述泵体10”的所述进液通道12”。
附图71至图76示出了本发明的所述乳液泵的所述塑料弹簧50”的另一个实施方式,与附图58至图65示出的所述塑料弹簧50”不同的是,在附图71至图76示出的所述塑料弹簧50”的这个具体示例中,所述塑料弹簧50”包括一个上环体51”、一个下环体52”、一个第一牵引部53a”、一个第二牵引部53b”、至少三个第一弹性腿54a”、至少三个第二弹性腿54b”以及一隔断环55”。
所述第一牵引部53a”和这些所述第一弹性腿54a”分别绕着所述塑料弹簧50”的中心轴线呈螺旋状地延伸,其中这些所述第一弹性腿54a”的一个端部分别向上延伸至和被连接于所述上环体51”,另一个端部分别向下延伸至和被连接于所述隔断环55”,其中所述第一牵引部53a”的一个端部向上延伸至和被连接于所述第一弹性腿54a”,另一个端部向下延伸至和被连接于所述第一弹性腿54a”,并且所述第一牵引部53a”和每个所述第一弹性腿54a”分别具有至少一个连接位置。所述第二牵引部53b”和这些所述第二弹性腿54b”分别绕着所述塑料弹簧50”的中心轴线呈螺旋状地延伸,其中这些所述第二弹性腿54b”的一个端部分别向上延伸至和被连接于所述隔断环55”,另一个端部分别向下延伸至和被连接于所述下环体52”,其中所述第二牵引部53b”的一个端部向上延伸至和被连接于所述第二弹性腿54b”,另一个端部向下延伸至和被连接于所述第二弹性腿54b”,并且所述第二牵引部53b”和每个所述第二弹性腿54b”分别具有至少一个连接位置。所述第一弹性腿54a”和所述第二弹性腿54b”的延伸方向相反,所述第一牵引部53a”和所述第二牵引部53b”的延伸方向相反。在所述塑料弹簧50”被组装于所述乳液泵100”的所述取液单元20”和所述弹簧座40”之间时,所述塑料弹簧50”的所述上环体51”抵靠于所述取液单元20”的所述头帽21”的所述头帽延伸嘴53”,所述塑料弹簧50”的所述下环体52”抵靠于所述弹簧座40”,所述塑料弹簧50”的所述第一牵引部53a”、所述第二牵引部53b”、这些所述第一弹性腿54a”、这些所述第二弹性腿54b”和所述隔断环55” 环绕于所述驱动杆24”的所述连接管243”和所述头帽21”的所述头帽安装部212”的外部。
在所述塑料弹簧50”被挤压时,所述第一牵引部53a”能够牵引这些所述第一弹性腿54a”,以将这些所述第一弹性腿54a”的变形方向限制在所述塑料弹簧50”的高度方向,从而阻止这些所述第一弹性腿54a”向所述塑料弹簧50”的四周膨大,所述第二牵引部53b”能够牵引这些所述第二弹性腿54b”,以将这些所述第二弹性腿54b”的变形方向限制在所述塑料弹簧50”的高度方向,从而阻止这些所述第二弹性腿54b”向所述塑料弹簧50”的四周膨大,通过这样的方式,被挤压的所述塑料弹簧50”能够避免剐蹭所述头帽21”的所述罩环214”的内壁和剐蹭所述泵壳10”的内壁,如此不仅能够提高用户在按压所述头帽21”时的手感和顺畅性,而且能够避免因所述塑料弹簧50”的这些所述第一弹性腿54a”和所述第二弹性腿54b”被所述头帽21”的所述罩环214”的内壁和/或所述泵壳10”的内壁卡住导致的失效问题。
并且,由于用于连接所述上环体51”和所述隔断环55”的这些所述第一弹性腿54a”的延伸方向和用于连接所述下环体52”和所述隔断环55”的这些所述第二弹性腿54b”的延伸方向相反,因此在所述塑料弹簧50”被挤压时,由所述上环体51”、所述第一牵引部53a”、这些所述第一弹性腿54a”和所述隔断环55”形成的所述塑料弹簧50”的一上段部分501”和由所述下环体52”、所述第二牵引部53b”、这些所述第二弹性腿54b”和所述隔断环55”形成的所述塑料弹簧50”的一下段部分502”的旋转方向相反,从而在所述塑料弹簧50”的内部形成相对作用力,避免所述上环体51”产生相对于所述头帽21”的转动和避免所述下环体52”产生相对于所述弹簧座40”的转动。换言之,在所述塑料弹簧50”被挤压时,所述上环体51”相对于所述头帽21”的位置保持不变,所述下环体52”相对于所述弹簧座40”的位置保持不变。
所述塑料弹簧50”的这些所述第一弹性腿54a”分别绕着所述塑料弹簧50”的中心轴线呈螺旋状地延伸,从而在所述塑料弹簧50”被挤压时,在不需要所述第一牵引部53a”辅助的情况下,这些所述第一弹性腿54a”即可使所述塑料弹簧50”的轴向方向均衡受力,因此在本发明中,所述塑料弹簧50”不要求所述第一牵引部53a”直接连接所述上环体51”和所述隔断环55”,如此有利于通过节省材料的方式降低成本和根据需要灵活地设计所述塑料弹簧50”的所述第一弹性腿54a”和所述第一牵引部53a”的结构关系。相应地,所述塑料弹簧50”的这些所述第二弹性腿54b”分别绕着所述塑料弹簧50”的中心轴线呈螺旋状地延伸,从而在所述塑料弹簧50”被挤压时,在不需要所述第二牵引部53b”辅助的情况下,这些所述第二弹性腿54b”即可使所述塑料弹簧50”的轴向方向均衡受力,因此在本发明中,所述塑料弹簧50”不要求所述第二牵引部53b”直接连接所述下环体52”和所述隔断环55”,如此有利于通过节省材料的方式降低成本和根据需要灵活地设计所述塑料弹簧50”的所述第二弹性腿54b”和所述第二牵引部53b”的结构关系。
所述第一牵引部53a”的顶部被连接于一个所述第一弹性腿54a”,其未被连接于所述上环体51”,这样,所述塑料弹簧50”能够避免所述第一牵引部53a”、所述第一弹性腿54a”和所述上环体51”之间形成三角形结构,所述第一牵引部53a”的底部被连接于一个所述第一弹性腿54a”,其未被连接于所述隔断环55”,这样,所述塑料弹簧50”能够避免所述第一牵引部53a”、所述第一弹性腿54a”和所述隔断环55”之间形成三角形结构,通过这样的方式,所述塑料弹簧50”的所述上段部分501”的整个高度方向均可以被压缩,以有利于增大所述塑料弹簧50”的形变量。相应地,所述第二牵引部53b”的底部被连接于一个所述第二弹性腿54b”,其未被连接于所述下环体52”,这样,所述塑料弹簧50”能够避免所述第二牵引部53b”、所述第二弹性腿54b”和所述下环体52”之间形成三角形结构,所述第二牵引部53b”的顶部被连接于一个所述第二弹性腿54b”,其未被连接于所述隔断环55”,这样,所述塑料弹簧50”能够避免所述第二牵引部53b”、所述第二弹性腿54b”和所述隔断环55”之间形成三角形结构,通过这样的方式,所述塑料弹簧50”的所述下段部分502”的整个高度方向均可以被压缩,以有利于增大所述塑料弹簧50”的形变量。
可以理解的是,所述塑料弹簧50”在被挤压时,所述上环体51”和所述隔断环55”相互配合均衡地压 缩所述第一牵引部53a”和这些所述第一弹性腿54a”,以使所述第一牵引部53a”和这些所述第一弹性腿54a”均产生变形而积蓄弹性势能,在这个过程中,所述第一牵引部53a”对这些所述第一弹性腿54a”进行牵引,以阻止这些所述第一弹性腿54a”向四周膨大而将所述第一弹性腿54a”的变形方向限制在所述塑料弹簧50”的高度方向,相应地,所述下环体52”和所述隔断环55”相互配合均衡地压缩所述第二牵引部53b”和这些所述第二弹性腿54b”,以使所述第二牵引部53b”和这些所述第二弹性腿54b”均产生变形而积蓄弹性势能,在这个过程中,所述第二牵引部53b”对这些所述第二弹性腿54b”进行牵引,以阻止这些所述第二弹性腿54b”向四周膨大而将所述第二弹性腿54b”的变形方向限制在所述塑料弹簧50”的高度方向。
在施加于所述塑料弹簧50”的外力撤销时,所述第一弹性腿54a”在回复初始状态的过程中提供主要的回复力,供驱使所述塑料弹簧50”的所述上段部分501”回复至初始状态,在这个过程中,所述第一牵引部53a”提供辅助的回复力,供辅助驱使所述塑料弹簧50”的所述上段部分501”回复至初始状态。相应地,所述第二弹性腿54b”在回复初始状态的过程中提供主要的回复力,供驱使所述塑料弹簧50”的所述下段部分502”回复至初始状态,在这个过程中,所述第二牵引部53b”提供辅助的回复力,供辅助驱使所述塑料弹簧50”的所述下段部分502”回复至初始状态。可见,在本发明的所述乳液泵100”中,所述塑料弹簧50”的所述第一牵引部53a”的主要作用是在所述塑料弹簧50”被挤压时牵引这些所述第一弹性腿54a”以阻止这些所述第一弹性腿54a”向四周膨大,次要作用是在挤压所述塑料弹簧50”的外力撤销后提供辅助的回复力,相应地,所述塑料弹簧50”的所述第二牵引部53b”的主要作用是在所述塑料弹簧50”被挤压时牵引这些所述第二弹性腿54b”以阻止这些所述第二弹性腿54b”向四周膨大,次要作用是在挤压所述塑料弹簧50”的外力撤销后提供辅助的回复力。
基于所述第一牵引部53a”和所述第二牵引部53b”在本发明的所述塑料弹簧50”中的作用,在本发明的一些实施例中,所述第一牵引部53a”的厚度尺寸可以被设计为小于所述第一弹性腿54a”的厚度尺寸,在保证所述第一牵引部53a”具有限制这些所述第一弹性腿54a”的变形方向和提供辅助的回复力的作用的情况下,不仅能够节省材料来降低所述塑料弹簧50”的成本,而且在按压所述头帽21”时能够减少所述第一牵引部53a”提供的阻力,以便于用户顺畅地按压所述头帽21”,相应地,所述第二牵引部53b”的厚度尺寸可以被设计为小于所述第二弹性腿54b”的厚度尺寸,在保证所述第二牵引部53b”具有限制这些所述第二弹性腿54b”的变形方向和提供辅助的回复力的作用的情况下,不仅能够节省材料来降低所述塑料弹簧50”的成本,而且在按压所述头帽21”时能够减少所述第二牵引部53b”提供的阻力,以便于用户顺畅地按压所述头帽21”。
基于所述第一牵引部53a”和所述第二牵引部53b”在本发明的所述塑料弹簧50”中的作用,在本发明的另一些实施例中,所述第一牵引部53a”的宽度尺寸可以小于所述第一弹性腿54a”的宽度尺寸,这样,在保证所述第一牵引部53a”具有限制这些所述第一弹性腿54a”的变形方向和提供辅助的回复力的作用的情况下,不仅能够节省材料来降低所述塑料弹簧50”的成本,而且相对于所述第一弹性腿54a”的外壁来说,所述第一弹性腿54a”的外壁可以内缩,即,所述第一弹性腿54a”的外壁和所述塑料弹簧50”的中心轴线之间的距离大于所述第一牵引部53a”的外壁和所述塑料弹簧50”的中心轴线之间的距离,相应地,所述第二牵引部53b”的宽度尺寸可以小于所述第二弹性腿54b”的宽度尺寸,这样,在保证所述第二牵引部53b”具有限制这些所述第二弹性腿54b”的变形方向和提供辅助的回复力的作用的情况下,不仅能够节省材料来降低所述塑料弹簧50”的成本,而且相对于所述第二弹性腿54b”的外壁来说,所述第二弹性腿54b”的外壁可以内缩,即,所述第二弹性腿54b”的外壁和所述塑料弹簧50”的中心轴线之间的距离大于所述第二牵引部53b”的外壁和所述塑料弹簧50”的中心轴线之间的距离。
在本发明中,所述塑料弹簧50”的所述第一牵引部53a”的延伸方向和所述第一弹性腿54a”的延伸方 向相反,以在所述第一牵引部53a”可靠地提供辅助的回复力的作用的同时,尽可能地减小所述第一牵引部53a”的厚度尺寸。例如,在一些实施例中,所述第一弹性腿54a”绕着所述塑料弹簧50”的中心轴线沿逆时针方向螺旋地延伸,所述第一牵引部53a”绕着所述塑料弹簧50”的中心轴线沿顺时针方向螺旋地延伸,通过这样的方式,在所述塑料弹簧50”被挤压时,一方面,所述第一牵引部53a”能够牵引这些所述第一弹性腿54a”,以将这些所述第一弹性腿54a”的变形方向限制在所述塑料弹簧50”的高度方向而阻止这些所述第一弹性腿54a”向四周膨大,另一方面,所述第一牵引部53a”沿高度方向被压缩,从而在撤销施加于所述塑料弹簧50”的压力后,所述第一牵引部53a”能够提供辅助的回复力,供所述塑料弹簧50”恢复初始状态,再一方面,所述第一牵引部53a”的厚度尺寸可以被进一步降低,这样不仅可以节省材料,而且能够增大所述塑料弹簧50”的形变量。具体而言,由于所述第一牵引部53a”的厚度尺寸可以更薄,所述塑料弹簧50”在被压缩后,相邻所述第一弹性腿54a”在高度方向的距离可以更近,从而增大所述塑料弹簧50”的形变量。
相应地,所述塑料弹簧50”的所述第二牵引部53b”的延伸方向和所述第二弹性腿54b”的延伸方向相反,以在所述第二牵引部53b”可靠地提供辅助的回复力的作用的同时,尽可能地减小所述第二牵引部53b”的厚度尺寸。例如,在一些实施例中,所述第二弹性腿54b”绕着所述塑料弹簧50”的中心轴线沿顺时针方向螺旋地延伸,所述第二牵引部53b”绕着所述塑料弹簧50”的中心轴线沿逆时针方向螺旋地延伸,通过这样的方式,在所述塑料弹簧50”被挤压时,一方面,所述第二牵引部53b”能够牵引这些所述第二弹性腿54b”,以将这些所述第二弹性腿54b”的变形方向限制在所述塑料弹簧50”的高度方向而阻止这些所述第二弹性腿54b”向四周膨大,另一方面,所述第二牵引部53b”沿高度方向被压缩,从而在撤销施加于所述塑料弹簧50”的压力后,所述第二牵引部53b”能够提供辅助的回复力,供所述塑料弹簧50”恢复初始状态,再一方面,所述第二牵引部53b”的厚度尺寸可以被进一步降低,这样不仅可以节省材料,而且能够增大所述塑料弹簧50”的形变量。具体而言,由于所述第二牵引部53b”的厚度尺寸可以更薄,所述塑料弹簧50”在被压缩后,相邻所述第二弹性腿54b”在高度方向的距离可以更近,从而增大所述塑料弹簧50”的形变量。
继续附图71至图76,所述第一牵引部53a”包括多个第一牵引段531a”,所述第一牵引段531a”的一个端部延伸至和被连接于相邻两个所述第一弹性腿54a”中的一个所述第一弹性腿54a”,另一个端部延伸至和被连接于相邻两个所述第一弹性腿54a”中的另一个所述第一弹性腿54a”,并且所述上环体51”不与最上方的所述第一牵引段531a”连接,这样,所述塑料弹簧50”能够避免在所述上环体51”、所述第一弹性腿54a”和最上方的所述第一牵引段531a”之间形成三角形结构,以在所述塑料弹簧50”被挤压时使得所述上环体51”和最上方的所述第一牵引段531a”之间的距离能够减小,相应地,所述隔断环55”不与最下方的所述第一牵引段531a”连接,这样,所述塑料弹簧50”能够避免在所述隔断环55”、所述第一弹性腿54a”和最下方的所述第一牵引段531a”之间形成三角形结构,以在所述塑料弹簧50”被挤压时使得所述隔断环55”和最下方的所述第一牵引段531a”之间的距离能够减小。也就是说,所述塑料弹簧50”的所述上段部分501”的整个高度位置均可以被压缩,以有利于增大所述塑料弹簧50”的形变量。
相应地,所述第二牵引部53b”包括多个第二牵引段531b”,所述第二牵引段531b”的一个端部延伸至和被连接于相邻两个所述第二弹性腿54b”中的一个所述第二弹性腿54b”,另一个端部延伸至和被连接于相邻两个所述第二弹性腿54b”中的另一个所述第二弹性腿54b”,并且所述隔断环55”不与最上方的所述第二牵引段531b”连接,这样,所述塑料弹簧50”能够避免在所述隔断环55”、所述第二弹性腿54b”和最上方的所述第二牵引段531b”之间形成三角形结构,以在所述塑料弹簧50”被挤压时使得所述隔断环55”和最上方的所述第二牵引段531b”之间的距离能够减小,相应地,所述下环体52”不与最下方的所述第二 牵引段531b”连接,这样,所述塑料弹簧50”能够避免在所述下环体52”、所述第二弹性腿54b”和最下方的所述第二牵引段531b”之间形成三角形结构,以在所述塑料弹簧50”被挤压时使得所述下环体52”和最下方的所述第二牵引段531b”之间的距离能够减小。也就是说,所述塑料弹簧50”的所述下段部分502”的整个高度位置均可以被压缩,以有利于增大所述塑料弹簧50”的形变量。
参考附图71,从侧视视角来看,所述第一牵引段531a”倾斜地延伸于相邻所述第一弹性腿54a”之间,例如,所述第一牵引段531a”的延伸方向和所述第一弹性腿54a”的延伸方向相反,如此在所述塑料弹簧50”被挤压时,所述第一牵引段531a”不仅可以牵引这些所述第一弹性腿54a”以阻止这些所述第一弹性腿54a”向四周膨大,而且在挤压所述塑料弹簧50”的外力撤销后提供辅助的回复力。另外,从俯视视角来看,所述第一牵引段531a”呈弧状地延伸于相邻两个所述第一弹性腿54a”之间,以使所述第一牵引段531a”的形状匹配所述塑料弹簧50”的整体形状,从而便于将所述塑料弹簧50”套装于所述驱动杆24”的所述连接管243”和所述头帽21”的所述头帽安装部212”。
相应地,继续参考附图71,从侧视视角来看,所述第二牵引段531b”倾斜地延伸于相邻两个所述第二弹性腿54b”之间,例如,所述第二牵引段531b”的延伸方向和所述第二弹性腿54b”的延伸方向相反,如此在所述塑料弹簧50”被挤压时,所述第二牵引段531b”不仅可以牵引这些所述第二弹性腿54b”以阻止这些所述第二弹性腿54b”向四周膨大,而且在挤压所述塑料弹簧50”的外力撤销后提供辅助的回复力。另外,从侧视视角来看,所述第二牵引段531b”呈弧状地延伸于相邻两个所述第二弹性腿54b”之间,以使得所述第二牵引段531b”的形状匹配所述塑料弹簧50”的整体形状,从而便于将所述塑料弹簧50”套装于所述驱动杆24”的所述连接管243”和所述头帽21”的所述头帽安装部212”。
接着,参考附图71至图76,在本发明中,相邻两个所述第一弹性腿54a”和被连接于这两个所述第一弹性腿54a”的相邻两个所述第一牵引段531a”之间形成平行四边形结构,从而在用户按压所述头帽21”时,所述塑料弹簧50”能够被顺畅地挤压变形。相应地,相邻两个弧第二弹性腿54b”和被连接于这两个所述第二弹性腿54b”的相邻两个所述第二牵引段531b”之间形成平行四边形结构,从而在用户按压所述头帽21”时,所述塑料弹簧50”能够被顺畅地挤压变形。

所述上段部分501”的所述第一装配环56a”和所述下段部分502”的所述第二装配环56b”被相互装配,并且所述第一装配环56a”和所述第二装配环56b”被构造为相对位置保持不动,所述上段部分501”的所述第一牵引部53a”的延伸方向和所述第二牵引部53b”的延伸方向相反,所述上段部分501”的所述第一弹性腿54a”的延伸方向和所述下段部分502”的所述第二弹性腿54b”的延伸方向相反。在所述塑料弹簧50”被组装于所述乳液泵100”的所述取液单元20”和所述弹簧座40”之间时,所述塑料弹簧50”的所述上段部分501”的所述上环体51”抵靠于所述取液单元20”的所述头帽21”的所述头帽延伸嘴53,所述下段部分502”的所述下环体52”抵靠于所述弹簧座40”,所述塑料弹簧50”的所述第一牵引部53a”、所述第二牵引部53b”、这些所述第一弹性腿54a”、这些所述第二弹性腿54b”、所述第一装配环56a”和所述第二装配环56b”环绕于所述驱动杆24”的所述连接管243”和所述头帽21”的所述头帽安装部212”的外部。
在所述塑料弹簧50”被挤压时,所述第一牵引部53a”能够牵引这些所述第一弹性腿54a”,以将这些所述第一弹性腿54a”的变形方向限制在所述塑料弹簧50”的高度方向,从而阻止这些所述第一弹性腿54a”向所述塑料弹簧50”的四周膨大,所述第二牵引部53b”能够牵引这些所述第二弹性腿54b”,以将这些所述第二弹性腿54b”的变形方向限制在所述塑料弹簧50”的高度方向,从而阻止这些所述第二弹性腿54b”向所述塑料弹簧50”的四周膨大,通过这样的方式,被挤压的所述塑料弹簧50”能够避免剐蹭所述头帽21”的所述罩环214”的内壁和剐蹭所述泵体10”的内壁,如此不仅能够提高用户在按压所述头帽21”时的手感和顺畅性,而且能够避免因所述塑料弹簧50”的这些所述第一弹性腿54a”和所述第二弹性腿54b”被所述头帽21”的所述罩环214”的内壁和/或所述泵体10”的内壁卡住导致的失效问题。
并且,由于所述上段部分501”的所述第一牵引部53a”的延伸方向和所述第二牵引部53b”的延伸方向相反,所述上段部分501”的所述第一弹性腿54a”的延伸方向和所述下段部分502”的所述第二弹性腿54b”的延伸方向相反,因此在所述塑料弹簧50”被挤压时,所述上段部分501”的旋转方向和所述下段部分502”的旋转方向相反,从而在所述上段部分501”和所述下段部分502”之间形成相对作用力,避免所述上环体51”产生相对于所述头帽21”的转动和避免所述下环体52”产生相对于所述弹簧座40”的转动。换言之,在所述塑料弹簧50”被挤压时,所述上环体51”相对于所述头帽21”的位置保持不变,所述下环体52”相对于所述弹簧座40”的位置保持不变。
所述塑料弹簧50”的所述上段部分501”的这些所述第一弹性腿54a”分别绕着所述塑料弹簧50”的中心轴线呈螺旋状地延伸,从而在所述塑料弹簧50”被挤压时,在不需要所述第一牵引部53a”辅助的情况下,这些所述第一弹性腿54a”即可使所述塑料弹簧50”的轴向方向均衡受力,因此在本发明中,所述塑料弹簧50”不要求所述第一牵引部53a”直接连接所述上环体51”和所述第一装配环56a”,如此有利于通过节省材料的方式降低成本和根据需要灵活地设计所述塑料弹簧50”的所述第一弹性腿54a”和所述第一牵引部53a”的结构关系。相应地,所述塑料弹簧50”的这些所述第二弹性腿54b”分别绕着所述塑料弹簧50”的中心轴线呈螺旋状地延伸,从而在所述塑料弹簧50”被挤压时,在不需要所述第二牵引部53b”辅助的情况下,这些所述第二弹性腿54b”即可使所述塑料弹簧50”的轴向方向均衡受力,因此在本发明中,所述塑料弹簧50”不要求所述第二牵引部53b”直接连接所述下环体52”和所述第二装配环56b”,如此有利于通过节省材料的方式降低成本和根据需要灵活地设计所述塑料弹簧50”的所述第二弹性腿54b”和所述第二牵引部53b”的结构关系。
所述第一牵引部53a”的顶部被连接于一个所述第一弹性腿54a”,其未被连接于所述上环体51”,这样,所述塑料弹簧50”能够避免所述第一牵引部53a”、所述第一弹性腿54a”和所述上环体51”之间形成三角形结构,所述第一牵引部53a”的底部被连接于一个所述第一弹性腿54a”,其未被连接于所述第一装配环56a”,这样,所述塑料弹簧50”能够避免所述第一牵引部53a”、所述第一弹性腿54a”和所述第一装配环56a”之间形成三角形结构,通过这样的方式,所述塑料弹簧50”的所述上段部分501”的整个高度方向均可以被压缩,以有利于增大所述塑料弹簧50”的形变量。相应地,所述第二牵引部53b”的底部被连接于一个所述第二弹性腿54b”,其未被连接于所述下环体52”,这样,所述塑料弹簧50”能够避免所述第二牵引部53b”、所述第二弹性腿54b”和所述下环体52”之间形成三角形结构,所述第二牵引部53b”的顶部被连接于一个所述第二弹性腿54b”,其未被连接于所述第二装配环56b”,这样,所述塑料弹簧50”能够避免所述第二牵引部53b”、所述第二弹性腿54b”和所述第二装配环56b”之间形成三角形结构,通过这样的方式,所述塑料弹簧50”的所述下段部分502”的整个高度方向均可以被压缩,以有利于增大所述塑料弹簧50”的形变量。
可以理解的是,所述塑料弹簧50”在被挤压时,所述上环体51”和所述第一装配环56a”相互配合均衡地压缩所述第一牵引部53a”和这些所述第一弹性腿54a”,以使所述第一牵引部53a”和这些所述第一弹性腿54a”均产生变形而积蓄弹性势能,在这个过程中,所述第一牵引部53a”对这些所述第一弹性腿54a”进行牵引,以阻止这些所述第一弹性腿54a”向四周膨大而将所述第一弹性腿54a”的变形方向限制在所述塑料弹簧50”的高度方向,相应地,所述下环体52”和所述第二装配环56b”相互配合均衡地压缩所述第二牵引部53b”和这些所述第二弹性腿54b”,以使所述第二牵引部53b”和这些所述第二弹性腿54b”均产生变形而积蓄弹性势能,在这个过程中,所述第二牵引部53b”对这些所述第二弹性腿54b”进行牵引,以阻止这些所述第二弹性腿54b”向四周膨大而将所述第二弹性腿54b”的变形方向限制在所述塑料弹簧50”的高度方向。
在施加于所述塑料弹簧50”的外力撤销时,所述第一弹性腿54a”在回复初始状态的过程中提供主要的回复力,供驱使所述塑料弹簧50”的所述上段部分501”回复至初始状态,在这个过程中,所述第一牵引部53a”提供辅助的回复力,供辅助驱使所述塑料弹簧50”的所述上段部分501”回复至初始状态。相应地,所述第二弹性腿54b”在回复初始状态的过程中提供主要的回复力,供驱使所述塑料弹簧50”的所述下段部分502”回复至初始状态,在这个过程中,所述第二牵引部53b”提供辅助的回复力,供辅助驱使所述塑料弹簧50”的所述下段部分502”回复至初始状态。可见,在本发明的所述乳液泵100”中,所述塑料弹簧50”的所述第一牵引部53a”的主要作用是在所述塑料弹簧50”被挤压时牵引这些所述第一弹性腿 54a”以阻止这些所述第一弹性腿54a”向四周膨大,次要作用是在挤压所述塑料弹簧50”的外力撤销后提供辅助的回复力,相应地,所述塑料弹簧50”的所述第二牵引部53b”的主要作用是在所述塑料弹簧50”被挤压时牵引这些所述第二弹性腿54b”以阻止这些所述第二弹性腿54b”向四周膨大,次要作用是在挤压所述塑料弹簧50”的外力撤销后提供辅助的回复力。

基于所述第一牵引部53a”和所述第二牵引部53b”在本发明的所述塑料弹簧50”中的作用,在本发明的另一些实施例中,所述第一牵引部53a”的宽度尺寸可以小于所述第一弹性腿54a”的宽度尺寸,这样,在保证所述第一牵引部53a”具有限制这些所述第一弹性腿54a”的变形方向和提供辅助的回复力的作用的情况下,不仅能够节省材料来降低所述塑料弹簧50”的成本,而且相对于所述第一弹性腿54a”的外壁来说,所述第一弹性腿54a”的外壁可以内缩,即,所述第一弹性腿54a”的外壁和所述塑料弹簧50”的中心轴线之间的距离大于所述第一牵引部53a”的外壁和所述塑料弹簧50”的中心轴线之间的距离,相应地,所述第二牵引部53b”的宽度尺寸可以小于所述第二弹性腿54b”的宽度尺寸,这样,在保证所述第二牵引部53b”具有限制这些所述第二弹性腿54b”的变形方向和提供辅助的回复力的作用的情况下,不仅能够节省材料来降低所述塑料弹簧50”的成本,而且相对于所述第二弹性腿54b”的外壁来说,所述第二弹性腿54b”的外壁可以内缩,即,所述第二弹性腿54b”的外壁和所述塑料弹簧50”的中心轴线之间的距离大于所述第二牵引部53b”的外壁和所述塑料弹簧50”的中心轴线之间的距离。
在本发明中,所述塑料弹簧50”的所述第一牵引部53a”的延伸方向和所述第一弹性腿54a”的延伸方向相反,以在所述第一牵引部53a”可靠地提供辅助的回复力的作用的同时,尽可能地减小所述第一牵引部53a”的厚度尺寸。例如,在一些实施例中,所述第一弹性腿54a”绕着所述塑料弹簧50”的中心轴线沿逆时针方向螺旋地延伸,所述第一牵引部53a”绕着所述塑料弹簧50”的中心轴线沿顺时针方向螺旋地延伸,通过这样的方式,在所述塑料弹簧50”被挤压时,一方面,所述第一牵引部53a”能够牵引这些所述第一弹性腿54a”,以将这些所述第一弹性腿54a”的变形方向限制在所述塑料弹簧50”的高度方向而阻止这些所述第一弹性腿54a”向四周膨大,另一方面,所述第一牵引部53a”沿高度方向被压缩,从而在撤销施加于所述塑料弹簧50”的压力后,所述第一牵引部53a”能够提供辅助的回复力,供所述塑料弹簧50”恢复初始状态,再一方面,所述第一牵引部53a”的厚度尺寸可以被进一步降低,这样不仅可以节省材料,而且能够增大所述塑料弹簧50”的形变量。具体而言,由于所述第一牵引部53a”的厚度尺寸可以更薄,所述塑料弹簧50”在被压缩后,相邻所述第一弹性腿54a”在高度方向的距离可以更近,从而增大所述塑料弹簧50”的形变量。
相应地,所述塑料弹簧50”的所述第二牵引部53b”的延伸方向和所述第二弹性腿54b”的延伸方向相反,以在所述第二牵引部53b”可靠地提供辅助的回复力的作用的同时,尽可能地减小所述第二牵引部53b”的厚度尺寸。例如,在一些实施例中,所述第二弹性腿54b”绕着所述塑料弹簧50”的中心轴线沿顺时针 方向螺旋地延伸,所述第二牵引部53b”绕着所述塑料弹簧50”的中心轴线沿逆时针方向螺旋地延伸,通过这样的方式,在所述塑料弹簧50”被挤压时,一方面,所述第二牵引部53b”能够牵引这些所述第二弹性腿54b”,以将这些所述第二弹性腿54b”的变形方向限制在所述塑料弹簧50”的高度方向而阻止这些所述第二弹性腿54b”向四周膨大,另一方面,所述第二牵引部53b”沿高度方向被压缩,从而在撤销施加于所述塑料弹簧50”的压力后,所述第二牵引部53b”能够提供辅助的回复力,供所述塑料弹簧50”恢复初始状态,再一方面,所述第二牵引部53b”的厚度尺寸可以被进一步降低,这样不仅可以节省材料,而且能够增大所述塑料弹簧50”的形变量。具体而言,由于所述第二牵引部53b”的厚度尺寸可以更薄,所述塑料弹簧50”在被压缩后,相邻所述第二弹性腿54b”在高度方向的距离可以更近,从而增大所述塑料弹簧50”的形变量。
继续附图77至图79,所述第一牵引部53a”包括多个第一牵引段531a”,所述第一牵引段531a”的一个端部延伸至和被连接于相邻两个所述第一弹性腿54a”中的一个所述第一弹性腿54a”,另一个端部延伸至和被连接于相邻两个所述第一弹性腿54a”中的另一个所述第一弹性腿54a”,并且所述上环体51”不与最上方的所述第一牵引段531a”连接,这样所述塑料弹簧50”能够避免在所述上环体51”、所述第一弹性腿54a”和最上方的所述第一牵引段531a”之间形成三角形结构,以在所述塑料弹簧50”被挤压时使得所述上环体51”和最上方的所述第一牵引段531a”之间的距离能够减小,相应地,所述第一装配环56a”不与最下方的所述第一牵引段531a”连接,这样,所述塑料弹簧50”能够避免在所述第一装配环56a”、所述第一弹性腿54a”和最下方的所述第一牵引段531a”之间形成三角形结构,以在所述塑料弹簧50”被挤压时使得所述第一装配环56a”和最下方的所述第一牵引段531a”之间的距离能够减小。也就是说,所述塑料弹簧50”的所述上段部分501”的整个高度位置均可以被压缩,以有利于增大所述塑料弹簧50”的形变量。
相应地,所述第二牵引部53b”包括多个第二牵引段531b”,所述第二牵引段531b”的一个端部延伸至和被连接于相邻两个所述第二弹性腿54b”中的一个所述第二弹性腿54b”,另一个端部延伸至和被连接于相邻两个所述第二弹性腿54b”中的另一个所述第二弹性腿54b”,并且所述第二装配环56b”不与最上方的所述第二牵引段531b”连接,这样所述塑料弹簧50”能够避免在所述第二装配环56b”、所述第二弹性腿54b”和最上方的所述第二牵引段531b”之间形成三角形结构,以在所述塑料弹簧50”被挤压时使得所述第二装配环56b”和最上方的所述第二牵引段531b”之间的距离能够减小,相应地,所述下环体52”不与最下方的所述第二牵引段531b”连接,这样,所述塑料弹簧50”能够避免在所述下环体52”、所述第二弹性腿54b”和最下方的所述第二牵引段531b”之间形成三角形结构,以在所述塑料弹簧50”被挤压时使得所述下环体52”和最下方的所述第二牵引段531b”之间的距离能够减小。也就是说,所述塑料弹簧50”的下段部分的整个高度位置均可以被压缩,以有利于增大所述塑料弹簧50”的形变量。
