Description

一种环保液体泵 技术领域
本发明涉及泵技术领域，尤其涉及一种所有零件均为全塑结构，能够回收现利用的环保液体泵。
背景技术
随着人民生活的不断提高，现在人们在关注自身健康卫生的同时，也越来越关心整个地球的环保问题，人们在洗手，洗脸或者沐浴的时候都习惯于借助一些清洁液体来进行，以维护自身的身体健康，但是正是由于这些清洁液的用量越来越大，由此产生的废弃泵体等垃圾也会越来越多，同时，现有的液体泵在使用过程中一旦打开按压泵头，随时会按压出液体，尤其是在打开后移动泵时，会因为喷射的误动作而喷出液体，既造成了浪费，同时还不利于环保，不能够随时锁止，给运输也带来了极大的不便。
因此，急需要设计一款能够根据需要及时锁止按压出液体的操作，同时，密封性能好、气体不容易进入液体容器导致液体容器内产生气泡，使液体容器内液体品质下降等问题的发生，可以随时锁止，所有零件均为全塑料结构，可以全部回收利用，环保无污染的液体泵。
中国专利文献(公告日：2012年5月23日，公告号：CN102464133 A)公开了全塑乳液泵，它涉及一种喷雾器的全塑乳液喷头组件。它包含吸管、塑料阀门、泵体外壳、大圈、活塞、阀针、开关、垫片、阀杆、塑料弹簧和喷嘴，喷嘴下方连接有阀杆，阀杆外壁套接有塑料弹簧，阀杆下端设置有阀针，阀针外侧套接有活塞，活塞上方设置有开关，活塞外壁与泵体外壳上端内壁相连，泵体外壳的上端外壁套接有大圈，大圈内侧上端设置有垫片，泵体外壳下端连接有吸管，吸管上端设置有塑料阀片。
上述技术方案虽然所有零件采用全塑料制作，不必分拣即可回收，节能环保，但是该技术方案中其塑料弹簧支撑在喷嘴与开关之间，整个外形庞大，不够精巧，而且用材较多，成本高，不适合大量的液体泵的使用。同时，该乳液泵其防止喷射的误动作需要转动阀杆，通过将其上的导向装置旋转到开关的挡环上面空间进行锁定，这种结构虽然也可以避免识动作使液体喷出，但是这种结构却需要额外操作，如果忘记转动阀杆，则同样不能够避免误操作的发生，操作极其不便。
发明内容
本发明的目的是提供一种能够在操作完一次按压出液后，自动锁止，密封性能好，所有零件均为全塑料结构，可以全部回收利用，环保无污染，在保证整体外形不变的情况下实现了液体泵的全塑设计，内部塑料弹簧与液体完全隔离，无接触，上液体快的环保液体泵。 该环保液体泵，通过在按压泵头与结合盖之间设计螺纹锁紧和止转锁紧，实现了按压处的双锁紧，使得按压处无液体溢出；通过在内螺纹管座与液体容器之间设置止转结构及螺纹锁紧结构，实现了液体容器的双锁紧设计，提升了密封性能；通过对弹性组件进行全新的结构设计，实现了弹性组件内部进气设计，弹性组件置于泵体内部液体外部，实现了与液体的完全隔离，不会因使用而使弹性组件受液体污染；实现了液体自活塞组件内部出液的设计，更能够控制压液的行程，能够满足不同液体容器压液行程的设计需要；实现了压液腔内部锁止密封式设计以及阀件之间的双弹性设计，密封性能好，更方便控制上液和出液。

锁止密封座6，设置在泵体1内部靠近阀件102处，实现对活塞组件4和阀件102的锁止并密封压液腔101。
内止转结构201和外止转结构301反向设置，如图8所示，外止转结构301均布在结 合盖的上端外部圆周上，外止转结构301包括一体设置的倾斜滑动卡接面306和反向卡钩307，如图6所示，内止转结构201与外止转结构301配合设置呈钩状结构，并且内止转结构201的钩状的倾斜度大于外止转结构的倾斜度。如图7所示，内止转结构201对称设置有两组，每组合设置有两个。需要进行止转使用时，内止转结构201沿外止转结构301上的倾斜滑动卡接面306滑入到反向卡钩307与其形成对钩配合结构，被锁止实现止转，而当需要解除止转时，稍用力反向转动按压泵头2使内止转结构201与反向卡钩307脱开，即可实现止转解锁。

如图14、15、16所示，所述的锁止密封座6为PP树脂材料制作的一体式全塑构件，所述的锁止密封座6包括锁止安装座61和锁止插座62，所述的锁止插座62内部环设呈锁止腔63，所述的锁止安装座61内部设置有阀件运动腔64，所述的阀件运动腔64与锁止安装座连接的腔壁上开设有进液口65，所述的阀件运动腔64与锁止腔63通过一隔板66相互阻隔上下不连通，阀件运动腔64的腔底设置有阀件限位结构67。在使用时，上部锁止插座62及其锁止腔63用于配合活塞组件进行密封锁止，而下部锁止安装座及其内部的阀件运动腔64是为了在上液过程中阀件102能够向上被顶起从而打开阀门，使液体进入到阀件运动腔64，进而通过进液口65进入到压液腔101完成上液动作，上液完成后阀件102回落实现对阀门的关闭。
还包括设置在泵体1上端外部用于连接液体容器的内螺纹管座10，所述的内螺纹管座10的内壁上设置有容器止转结构11。容器止转结构11与结合盖上的内止转结构采用相同结构设置，液体容器外壁上设置有管座止转结构，用于与容器止转结构11配合实现液体容器与内螺纹管座10之间的止转，当然液体容器与内螺纹管座还通过螺纹进行了连接。
如图17a、17b、17c所示，该环保液体泵，组装使用时，其结构为泵体1的底部卡接密封安装有锁止密封座6，而在阀座109内部装有阀件102，阀件为一PP树脂材料制作的全塑料结构的阀球，当然也可以是气阀等能够实现阀门开启或闭关的构件，而在泵体下端的过液缩体107的下端内部形成有插管腔110，插管腔内部插接有吸液管12，吸液管12插入到液体容器13内部，用于吸取液体容器内部的液体。全塑弹簧座51安装在泵体1的内部上端通过安装台502和弹性件安装结构104配合实现与泵体内部紧密封连接，保证在使用过程中不会移动，全塑弹簧座内部设置有座腔501，座腔501既用于安装全塑弹簧，同时还用作气体通道，而全塑弹簧52内部为空腔结构，全塑弹簧的弹簧上座507上开设有进气口508，弹簧体内部的空腔结构设置为气体通道8，气体通道8与进气口508以及座腔501连通，全塑弹簧52的下端设置有弹簧下座，弹簧下座505压设在全塑弹簧座51的底壁上。活塞42设置在活塞杆41下端的行程阀杆段405上，而活塞杆41的上端穿过全塑弹簧52的内部的气体通道8与按压泵头2上的滑动压杆203内部的过液腔205插接连接，并通过过液腔内壁上的活塞杆密封插接结构206与活塞杆上的密封连接结构403配合密封连接，而活塞杆上的弹簧压座402压设在全塑弹簧的上端。在活塞处于上限位状态，压液腔101内部充满有液体时，活塞的上部的上限位锁止结构408与全塑弹簧下部的活塞锁止座504密封连接阻断了外部气体通 道。结合盖3的上座31内部的滑动气腔302与滑动压杆203配合，使滑动压杆203可以沿滑动气腔302上下滑动，同时还能够保证外部气体的进入，而结合盖上的下盖则通过其上的密封连接环腔305与泵体1的上端插卡式密封连接，在下盖的内部形成有下盖气腔304，滑动气腔302和下盖气腔304上下连通形成连通外部的进气腔7。活塞杆中部的气道密封结构404与全塑弹簧座51的下端设置的通气道503在活塞杆向下运动过程中相互脱离密封，进气腔7与全塑弹簧座内部的座腔501、全塑弹簧上的进气口508、全塑弹簧内部的进气道8以及弹簧座下部的通气道503、全塑弹簧座外壁与泵体内壁之间的形成的气压腔9，相互之间上下连通形成外部气体的气道，最后经泵体侧壁上的出气孔113进入到液体容器13内部(见图18a、18b)，此时液体容器内部的气压与外部气压平衡。阀件102处于密封状态，液体容器内部的液体与压液腔不连通，此时，如果需要进行出液操作，向下按压按压泵头，压液腔101内部的液体则由于受到挤压，从活塞杆上的进液口406进入到出液腔401被压出(见图17a、17b、17c)，在压液过程中，外部气体同步进入到液体容器中，当压液完成即活塞与锁止密封座6密封连接时，活塞的上部的上限位锁止结构408与全塑弹簧下部的活塞锁止座504密封连接阻断气体通道。当松开按压泵头2后，全塑弹簧复位，活塞在活塞杆的带动下向上运动，活塞实现对压液腔内部一个抽真空动作，此时，液体容器内部的气压大于压液腔内部的气压，阀件向上打开，液体自液体容器内部经吸液管12抽吸到压液腔101内部(见图19a、19b)，可以进行下一次按压出液。
而下面详细说明该环保液体泵的出液过程，如图17a、17b、17c所示，在使用时，向下按压按压泵头2，按压泵头上的滑动压杆带动活塞杆及其上的活塞向下运动，此时，活塞向下挤压压液腔，压液腔内部的液体被挤压，活塞杆则与活塞脱离密封配合，活塞杆上的行程阀杆段向压液腔延伸，使得进液口与压液腔内部连通，此时，压液腔内部的液体则在压力的作用下向活塞杆内部的出液腔流动，并通过滑动压杆上的过液腔经按压泵头的出液道202端部的出液口207喷出，实现了按压出液的操作。
如见图19a、19b所示，松开按压泵头，全塑弹簧带动活塞杆向上运动进行复位，此时，液体容器内部的气压大于压液腔内部的气压，阀件被向上顶起打开，液体容器内部的液体通过吸液管被吸到压液腔，可以进行下一次的按压出液操作。
如图20所示，如果使用者并不需要连续使用让其出液体，则在液体被按压出来后，继续向下压下按压泵头，此时，按压泵头带动滑动压杆最后带动活塞杆及活塞继续向下运动，直至与锁止密封座密封插接在一起，此时，阀件密封在阀座上，实现了对压液腔的密封，同时，转动按压泵头使其上的内止转结构与结合盖上的外止转结构配合实现止转，从而实现了 对泵体的双重锁止，既防止了儿童的误操作，同时，在移动或倾倒过程中不会有液体溢出，不会污染环境。此时该环保液体泵处于完全的锁止状态，一如出厂时的被锁止的状态：按压泵头与结合盖之间通过止转结构和螺纹连接锁紧，内螺纹管座与液体容器之间的通过止转结构和螺纹连接锁紧，活塞组件与锁止密封座之间处于插接密封锁止状态，活塞杆上的气道密封结构404与全塑弹簧座下端的通气道503配合密封实现了气道的密封，外部气体与液体容器内部隔离。而使用时，稍用力反射转动按压泵头，将按压泵头与结合盖之间的止转结构以及螺纹连接结构打开后即可进行上液出液操作。
该环保液体泵可以实现上液操作的锁止，避免了液体的溢出，无污染环保，有效避免了现有技术中液体泵在一次按压出液后，容器内部的液体自动上液到压液腔，在泵体倾倒或运输过程中容易溢出的问题。该环保液体泵，全部构件除了液体容器与螺纹管座之间的密封垫片外均采用PP树脂材料制作，可以全部回复利用，实现了环保式的设计，并且达到了泵体需要的全部性能要求，特别是是弹簧也采用PP树脂材料制作的成全塑结构，克服了现有的全塑弹簧只能外部使用，无法实现既能够保证体积小，可以内置于泵体内部，又能够满足弹簧的各项性能要求，而本发明中的全塑弹簧设置在泵体内部，且与压液腔隔离，在使用过程中不会与液体接触，从而避免了弹簧在使用过程中由于受液体污染而导致性能下降的问题，同时，本申请中的全塑弹簧还作用气体通道设计使用，使得泵的整体结构更加紧凑合理，在不改变泵的性能及外形要求的前提下，使用更加广泛。该环保液体泵，通过在按压泵头和结合盖上配合设置有止转结构，在内螺纹管座与液体容器连接处设置止转结构，使得该液体泵在运输和使用过程中能够有效防止液体流出，污染环保，可有效防止儿童的误操作，避免发生意外。
本领域普通技术人员在基于上述实施例说明的情况下将能够实现本发明。此外，上述实施例只是本发明的实施例通常仅是本发明一部分的实施例，而不是全部的实施例。因此，基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他技术文案及实施例，都应当属于本发明保护的范围。
