Description
本申请涉及按压泵技术领域，尤其涉及一种按压泵结构。
按压泵是一种通过头帽按压使液体或乳液从容器内流出的化妆用品，一般由喷头和瓶体两部分组成，属液态霜类化妆品的容器之一。其工作原理是：通过按压头帽往复运动造成瓶体内容积周期性地增大和缩小，使液体的压力增加，从而吸排瓶体内的液体。但目前市场上绝大多按压泵采用钢丝弹簧，钢丝弹簧在液体的浸泡下，难免发生化学反应，影响产品弹力性能，更使液体变质污染影响使用者的身体健康。为此一些按压泵采用外置塑料弹簧结构，外置塑料弹簧采用螺旋形结构设计，申请号为202110305663.4的中国发明专利申请，公开了一种具有塑料弹簧的按压泵”，公布日2021年06月29日。但上述产品和同类产品的外置弹簧螺旋结构设计欠佳，导致塑料弹簧较难与泵芯组立一体生产装配，鸭嘴与阀杆之间稳定性欠佳，使用寿命较短，回复力和复位效果较差等问题。
本申请提供一种按压泵结构，该按压泵结构能够实现同类产品的塑料弹簧与泵芯组立一体生产装配，提高塑料弹簧的回复力和复位效果，提高稳定性。
为实现上述发明目的，本申请采用以下技术方案：
一种按压泵结构，包括泵体、连接座、阀杆和弹簧，所述阀杆通过所述连接座安装到所述泵体。所述阀杆与所述连接座之间形成弹簧腔，所述弹簧放置于所述弹簧腔中。
进一步，所述阀杆包括内阀杆和外阀杆壁，所述内阀杆和外阀杆壁之间的环形空间为所述弹簧腔。所述弹簧一端与所述弹簧腔顶部的外阀杆壁相抵，所述弹簧的另一端与所述连接座相抵。
进一步的，所述连接底座的底部设置环形圈台，所述弹簧与所述环形圈台相抵或套装在所述圈台上。
进一步的，所述环形圈台内壁设置导向槽，所述导向槽的一侧上方设置与导向槽周向相通的锁紧槽，锁紧槽内设有凸起的锁紧块，阀杆的锁紧筋端部由导向槽滑动至锁紧槽实现锁紧限位，限制了阀杆继续下压或相对于连接座转动，也能够加强阀杆与连接座之间的连接稳定性。
.
进一步的，所述内阀杆侧面设置锁紧筋，所述弹簧的内壁设置缺口槽，所述锁紧筋与所述缺口槽相配合，能够更好地固定弹簧的位置，使得弹簧与阀杆之间不易发生相对转动。
进一步的，所述弹簧为螺旋型塑料弹簧，所述螺旋型塑料弹簧两端的圈口之间对称设置上下螺旋式平行的弹性螺旋筋。
进一步的，所述弹性螺旋筋之间采用加强筋连接。
另一种改进，所述弹簧为波纹管型塑料弹簧，所述波纹管型塑料弹簧呈宝塔形，一端的外径大于另一端。

如图1所示，一种按压泵结构，包括泵体13、连接座17、阀杆110和螺旋型塑料弹簧19，阀杆110通过连接座17安装到泵体13。该按压泵结构还包括鸭嘴111、垫片18、大圈16、活塞15、阀针14、塑料球12和吸管11。
如图1所示，泵体13内的进液孔设有塑料球12，吸管11插入泵体13底部外侧的进液孔，泵体13内的活塞15夹持固定于阀杆110与阀针14的连接处。泵体13一侧活塞处设有通孔131。阀杆110伸出泵体13和连接座17，阀杆110外径设有螺旋型塑料弹簧19，顶部设有鸭嘴111。连接座17的座口扣合固定于泵体13的泵口，连接座17的座口与泵体13的泵口外径外翻边之间夹持固定住大圈16的中心孔，大圈16内泵体13的外翻边底部设有垫片18。连接座17的下腔室扣合伸入泵体14的泵口内，螺旋型塑料弹簧19位于阀杆110的弹簧腔1102与连接座17的下腔室套合的弹簧腔1101内。
螺旋型塑料弹簧19的一端相抵于阀杆110外径的弹簧腔顶部，螺旋型塑料弹簧19的另一端相抵于连接座17处孔口边沿。如图3至5所示，螺旋型塑料弹簧19两端的圈口193之间对称设有上下螺旋式平行交叉的弹性螺旋筋191，弹性螺旋筋191的上下连接点对称设置于螺旋型塑料弹簧19两端的圈口193两侧，一侧的上下弹性螺旋筋191之间分别对称设有加强筋192，螺旋型塑料弹簧19的圈口193、弹性螺旋筋191、加强筋192一体注塑成型。螺旋型塑料弹簧19的上下两端圈口193设有圆周固定胶位，连接座17与阀杆110组装后内部高度小于螺旋型塑料弹簧19的高度。
如图2所示，连接座17的中心孔处向上凸起设有环形圈台171，环形圈台171与螺旋型塑料弹簧19一端相抵。活塞15上方阀杆110的杆部外径对称设有凸起的锁紧筋1101，锁紧筋1101对应的连接座17环形圈台171处内径设置导向槽1711，导向槽1711的一侧上方设有相通的锁紧槽1712，锁紧槽1712内设有凸起的锁紧块，阀杆110的锁紧筋1101处端部由导向槽滑1711动至锁紧槽1712实现锁紧限位。阀杆110的顶部圈面设有扣槽，鸭嘴111的进液口套入阀杆110的出液孔，鸭嘴111的进液口外侧端面与阀杆110的扣槽扣合。
使用时，旋转鸭嘴带动阀杆至解锁状态，按压鸭嘴，液体即可从鸭嘴挤出。使用后，旋转鸭嘴带动阀杆至关闭状态，阀杆的锁紧筋与连接座的锁紧槽处相抵锁紧，鸭嘴即可关闭无法下压操作。如图2所示，连接座的环形圈台亦可设置导气孔1713，螺旋型塑料弹簧即可替换为其它塑料弹簧使用。同时，为了进一步提高螺旋型塑料弹簧的圈口处稳定性，螺旋型塑料弹簧两端的圈口内径凸起并对称设有缺口，螺旋型塑料弹簧的缺口与阀杆的锁紧筋套合。
该螺旋型塑料弹簧采用全塑弹簧，螺旋型塑料弹簧的结构形状类似与钢丝弹簧样式，为两侧对称并上下螺旋式平行交叉的螺旋结构，上下两端的圈口设有圆周固定胶位，螺旋型塑料弹簧的圈口处内圈与阀杆的锁紧筋之间进行限位，并固定螺旋型塑料弹簧位置，不易发生错位的现象。螺旋型塑料弹簧的圈口分别与阀杆的弹簧腔顶部平面，及连接座的环形圈台处平面进行贴合，连接座与阀杆组装后内部高度小于螺旋型塑料弹簧的高度，便于组装螺旋型塑料弹簧后形成上下受压的状态。螺旋型塑料弹簧的中间部分采用螺旋结构类似与钢丝弹簧形式，在螺旋部分周边两侧分别设有两个的弹性连接片作为加强筋，防止在下压时不易向外扩张变形，及伸缩变形及因歪曲严重而导致变形无法复位，影响螺旋型塑料弹簧的正常工作。该螺旋型塑料弹簧的工作原理具体如下：当螺旋型塑料弹簧受到向下的外作用力时，中间螺旋式设计在力的作用下受力变形，同时压缩后因螺旋式筋位顺势有一个向上的回弹力；当向下的外作用力消失后，螺旋式筋位顺势回弹，弹簧复位。
综上所述，上述螺旋型塑料弹簧采用高弹性耐热性分子材料制成，由于该零件需受外力而变形，所以其具有高弹性变形系数，不然无法有效实现回弹功能。众所周知普通材质的变形体，由于本身材质较为柔软，特别是高温状态下极易发生严重收缩、导致永久性的变形从而丧失变形体的作用，但高弹性耐热性分子材料制成的变形体具有高耐热性的特点，不受高温收缩影响而降低弹性，高温下仍能正常变形及恢复，大大提高产品质量及使用寿命。同时，上述螺旋型塑料弹簧作为塑料弹簧替代钢丝弹簧，实现整个产品为全塑产品，在制作过程中无毒无害且易降解易于回收利用，减免环境污染危害，大大提高原料重复利用和可持续性。
