如图1至图5所示，在本实施例中，所述锁瓶盖3内还设置有垫片10，所述的垫片10为环形结构；起到密封瓶体的作用。
如图1至图5所示，在本实施例中，所述的泵室2的下端呈锥形，所述的单向阀5为设置在泵室2下端的泵珠。
如图1至图5所示，在本实施例中，所述的泵体1并位于单向阀5的下方还设置有引液管11。
如图1至图5所示，在本实施例中，所述的乳液泵为塑料材质。本发明的所有零部件为塑料材质，避免了液体的腐蚀，结构轻巧，方便回收利用，节能环保。
工作原理：
1、按压弯嘴，克服弹簧弹力带动泵杆下移，活塞因与泵室产生摩擦滞后，此时泵杆与活塞之间的通道被打开，继续下移泵杆，上限位凸环则顶住活塞一起下移，可将泵室内腔局部气体从抽吸通道排出；
2、松开弯嘴时，在弹簧力作用下复位，活塞滞后，活塞与泵杆 间的通道瞬间被密封，泵室内腔形成局部真空，在大气压力的作用下可将溶液从引液管引入并冲开泵珠吸进泵室内腔，继续按压时可将溶液从弯嘴喷出。
