具体实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进行清楚、完整地描述。
本发明提供了一种单一材料全塑乳液泵，其实施例如图1至图8所示，包括相同塑料材质制成的主体10、按头20、筒身30、单向出液机构40和管状弹簧50；主体10内部设有导向孔11，导向孔11导通主体10相背离的两端口；按头20以可按压的方式与主体10的一端口插装连接，按头20设有出液通道21；筒身30与主体10的另一端口插装连接，筒身30包围于导向孔11外，筒身30的底壁设有进液通道31；单向出液机构40穿过导向孔11，单向出液机构40设有导入通道41和导出通道42，导出通道42与出液通道21连接导通，在按头20按下时，单向出液机构40用于导通导入通道41和导出通道42；管状弹簧50压缩于单向出液机构40与筒身30的底壁之间，管状弹簧50的一端与导入通道41连接导通，管状弹簧50的另一端与进液通道31连接导通。
在进行应用时，会将单一材料全塑乳液泵与存液瓶60装配使用，所以通过对按头20进行按压操作，管状弹簧50将会在压缩和伸展两种状态中切换，从而导致管状弹簧50内部能够形成气压差，以此将存液瓶60内的乳液经进液通道31抽入至管状弹簧50内。
由于按头20的下压将带动单向出液机构40进行联动，以实现导入通道41和导出通道42从关断变为导通的切换，所以在导入通道41和导出通道42导通 后，管状弹簧50内的乳液便可依次流经导入通道41、导出通道42和出液导通，以此实现乳液的输出。
需要指出，由于此实施例包括相同塑料材质制成的主体10、按头20、筒身30、单向出液机构40和管状弹簧50，所以整个乳液泵均由相同的材质制成，在进行回收时无需进行材质分类，大大降低的回收难度和回收成本，切实解决了现有乳液泵分类回收困难的问题。
其中，为确保产品强度高、加工简便、以及回收利用容易，此实施例优选设置单一材料全塑乳液泵为聚乙烯制成；聚乙烯(polyethylene，简称PE)是乙烯经聚合制得的一种热塑性树脂，在工业上，也包括乙烯与少量α-烯烃的共聚物；聚乙烯无臭，无毒，手感似蜡，具有优良的耐低温性能(最低使用温度可达-100～-70℃)，化学稳定性好，能耐大多数酸碱的侵蚀(不耐具有氧化性质的酸)，常温下不溶于一般溶剂，吸水性小，电绝缘性优良。
如图1、以及图7至图10所示，单向出液机构40包括连杆43和活塞单元44；连杆43穿过导向孔11，连杆43内设有导出通道42，导出通道42贯通连杆43的两端；活塞单元44滑动安装于筒身30内，活塞单元44与连杆43连接，活塞单元44上设有导入通道41。
在进行应用时，活塞单元44能够在筒身30内进行直线往返移动，所以当按下按头20后，按头20将带动连杆43和活塞单元44一同下移，以此实现对管状弹簧50的压缩操作；而在停止对按头20进行按压后，管状弹簧50将因恢复形变而推动活塞单元44、连杆43和按压一同上移；所以在采用上述结构后，则实现了按头20与管状弹簧50之间的联动控制。
如图1、图6至图8、以及图11至图14所示，筒身30邻近导向孔11的周壁上设有导气孔32，导气孔32与筒身30的内部导通；活塞单元44包括回气活塞45和进液活塞46；回气活塞45滑动安装于筒身30内，回气活塞45设有将自身贯穿的气塞穿孔451；进液活塞46滑动安装于回气活塞45与管状弹簧50之间，进液活塞46与管状弹簧50套接；进液活塞46设有将自身贯穿的液塞穿孔461，多个液塞穿孔461均与管状弹簧50内部导通；连杆43穿过气塞穿孔451与进液活塞46连接固定，连杆43、回气活塞45和进液活塞46之间为联动结构，连杆43的移动用于控制回气活塞45与进液活塞46分离和抵接，回气活塞45与进液活塞46的分离用于形成导入通道41。
在按下按头20时，连杆43将往筒身30内部移动，然后连杆43的移动将会带动回气活塞45与进液活塞46相互分离，以利用回气活塞45与进液活塞46之间的间隙形成导入通道41，从而使得管状弹簧50内的乳液将可依次流经液塞穿孔461、导入通道41、导出通道42和出液通道21后输出。
在停止对按头20进行按压时，连杆43将往移离筒身30的方向移动，然后连杆43的移动将会带动回气活塞45与进液活塞46相互抵接，以次关断导入通道41，从而实现对乳液的密封保存。
需要指出，在回气活塞45往筒身30底壁移动后，导气孔32将不会受到回气活塞45的遮挡，所以导气孔32将可实现筒身30内部的压差调节，以确保管状弹簧50能够顺利的恢复至初始状态。
如图7至图14所示，回气活塞45围绕气塞穿孔451的周侧设有一圈导向壁452；进液活塞46设有固定槽462，多个液塞穿孔461围绕固定槽462的周侧布置；连杆43置于筒身30内的一端设有推顶柱431、导向筋432和一圈限位壁433；推顶柱431与导出通道42的端口分离相对布置，推顶柱431穿过气塞穿孔451***固定槽462内，推顶柱431与固定槽462连接固定；多条导向筋432围绕推顶柱431的周侧分离布置，多条导向筋432均连接于导出通道42端口周缘与推顶柱431周壁之间；限位壁433包围于多根导向筋432的周侧外，限位壁433与多根导向筋432之间围成限位槽47，限位槽47内***有导向壁452。
在按下按头20时，连杆43将往筒身30内部移动，所以连杆43将可推动进液活塞46往筒身30底部移动，实现了进液活塞46与回气活塞45的分离，即将导入通道41打开；由于随着连杆43往筒身30内部的移动，导向壁452最终将与限位槽47的底壁抵接，即连杆43的移动也将实现回气活塞45的同步移动，回气活塞45与进液活塞46将在保持分离的状态下持续往筒身30内部移动，确保了乳液能够持续流经导入通道41进行输送。
在停止对按头20进行按压时，连杆43将往移离筒身30的方向移动，所以连杆43将可拉动进液活塞46移向回气活塞45，直至进液活塞46与回气活塞45相互抵接，从而实现进液活塞46和回气活塞45的同步移动；由于回气活塞45与进液活塞46将在保持抵接的状态下持续往远离筒身30底壁的方向移动，所以确保了导入通道41的关断，避免乳液在按头20未按压时流出。
如图1、图2和图4所示，主体10内部设有按压腔12和装瓶腔13，按压腔12与装瓶腔13分隔布置，导向孔11导通按压腔12和装瓶腔13；按压腔12与按头20插装连接；装瓶腔13与筒身30插装连接，装瓶腔13的内周壁与筒身30的外周壁相互分离，装瓶腔13的内周壁设有内螺纹。
譬如按压腔12的开口部位可设计为往内收窄的结构，按头20的下部可设计为往外扩展的结构，所以当按头20***按压腔12后，按头20与按压腔12之间将可形成限位的扣合结构，以防止按头20从按压腔12内脱出。
而装瓶腔13与筒身30之间的间隙则可用于安装存液瓶60，譬如存液瓶60的端口可设置外螺纹，存液瓶60便可与装瓶腔13的内周壁螺纹连接，以此实现乳液泵与存液瓶60之间的安装固定。
如图1、图2、图3、图4和图6所示，筒身30的朝向导向孔11的端口外周缘设有一圈凸缘33，凸缘33与装瓶腔13的腔底抵接；单一材料全塑乳液泵还包括垫片70，垫片70套于筒身30外，垫片70与凸缘33抵接。
在采用此设置方式后，若乳液泵与存液瓶60进行安装固定，垫片70便会置于存液瓶60端口与凸缘33之间，从而能够利用垫片70加强乳液泵与存液瓶60之间的安装密封性。
如图1、图6和图15所示，管状弹簧50设有单向阀51，单向阀51遮盖进液通道31，单向阀51用于控制进液通道31往管状弹簧50内部单向进液。
在增设单向阀51后，单向阀51只允许向管状弹簧50内部输入乳液，并防止了管状弹簧50内部的乳液返回至存液瓶60内，从而确保用户在操作使用时的流畅性。
如图1、图6和图15所示，单向阀51包括连接筋511和弹性膜512；多根连接筋511的一端均与管状弹簧50的内周壁连接，多根连接筋511的另一端均与弹性膜512的周缘连接；弹性膜512遮盖进液通道31，弹性膜512用于受力产生形变以解除对进液通道31的遮盖。
譬如管状弹簧50内外压差平衡或管状弹簧50处于压缩时，单向阀51将会遮盖进液通道31，从而防止了管状弹簧50内的乳液返回至存液瓶60内；当管状弹簧50因压差变化而恢复伸展时，压差变化将会形成吸力，以此拉动弹性膜512往按头20的方向弯曲形变，从而使得弹性膜512解除对进液通道31的遮盖，实现了乳液往管状弹簧50内的输送。
如图1至图3所示，单一材料全塑乳液泵还包括吸管80，吸管80设于筒身30外，吸管80与进液通道31连接导通。
在设置吸管80后，将可利用吸管80延伸至存液瓶60的底部，从而确保能够更充分的对乳液进行抽取。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
