为了解决上述技术问题，本发明还提供了一种单一材料的储料瓶，所述储料瓶装配有上述的全塑泵，所述导料胶管置于所述储料瓶内。
本发明的有益效果如下：
由于本发明为一种单一材料的全塑泵，包括塑料按压头、塑料泵壳、塑料 活塞机构和塑料复位弹簧，所以整体的材质均为塑料、软胶等，譬如塑料复位弹簧则完全取替了现有的金属弹簧，即在进行回收的时候无需再进行拆解操作，直接对全塑泵进行回收处理即可，大大提高了回收效率，也大幅降低了回收成本，切实解决了现有泵头回收困难的问题。

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的全塑泵，其实施例如图1至图4所示，包括塑料按压头10、塑料泵壳20、塑料活塞机构30和塑料复位弹簧40；塑料按压头10以可按压的方式插入塑料泵壳20内，塑料按压头10上设有出料孔11，出料孔11与塑料活塞机构30的出料端连接导通；塑料活塞机构30设于塑料按压头10和塑料泵壳20的内部，塑料活塞机构30的进料端连接导通有导料胶管50，塑料活塞机构30用于控制出料孔11和导料胶管50的通闭；塑料复位弹簧40套于塑料活塞机构30外，塑料复位弹簧40压缩于塑料按压头10与塑料泵壳20之间。
在未进行按压时，塑料活塞机构30处于关闭的状态，所以将会切断出料孔11与导料胶管50之间的导通，从而无法实现出料；而在进行按压后，塑料按压头10将会往塑料泵壳20的内部移动，并控制塑料活塞机构30变为打开的状态，以将出料孔11与导料胶管50导通，从而实现出料操作；待取消对塑料按压头10进行按压后，塑料复位弹簧40将会推动塑料按压头10自动复位。
综上可知，由于本发明为一种单一材料的全塑泵，包括塑料按压头10、塑料泵壳20、塑料活塞机构30和塑料复位弹簧40，所以整体的材质均为塑料、软胶等，譬如塑料复位弹簧则40完全取替了现有的金属弹簧，即在进行回收的时候无需再进行拆解操作，直接对全塑泵进行回收处理即可，大大提高了回收效率，也大幅降低了回收成本，切实解决了现有泵头回收困难的问题。
如图1、图3和图4所示，此实施例优选设置塑料泵壳20的端口处设有一圈按头导向槽21，塑料按压头10滑动插入按头导向槽21内。
在采用此设置方式后，按头导向槽21实质就限定了塑料按压头10的移动轨迹，从而使得塑料按压头10只能在图示方向中进行上下移动，确保了塑料按压头10不会在操作过程中产生移位偏移，为整个按压操作过程提供了更为良好的使用体验。
如图1、图3和图4所示，此实施例优选设置塑料按压头10内部设有输料管12，输料管12与出料孔11连接导通；塑料泵壳20内设有第一空腔221、第二空腔222和导向孔23，导向孔23导通第一空腔221和第二空腔222，第一空腔221内设有塑料复位弹簧40；塑料活塞机构30的出料端与输料管12连接导通，塑料活塞机构30活动穿插于导向孔23内，塑料活塞机构30的进料端穿过 第二空腔222与导料胶管50连接导通；在采用此设置方式后，若对塑料按压头10进行按压，则可带动塑料活塞机构30在导向孔23内产生移动，以实现塑料活塞机构30的通闭状态控制。
具体的，此实施例塑料活塞机构30的开闭控制结构如图1、图3和图4所示，此时的塑料活塞机构30包括活塞缸壳31、泵料单元32和套管33；活塞缸壳31设于第二空腔222内，活塞缸壳31为两端开口结构，活塞缸壳31的一端口包围于导向孔23外，活塞缸壳31的另一端口与导料胶管50连接导通；泵料单元32以可进行活塞运动的方式安装于活塞缸壳31内；套管33活动穿插于导向孔23内，套管33外套有塑料复位弹簧40，套管33的一端与输料管12固定套接导通，套管33的另一端穿过导向孔23与泵料单元32套接导通，套管33的移动用于控制泵料单元32通闭出料孔11和导料胶管50。
在未进行按压操作时，泵料单元32置于活塞缸壳31的上方，且泵料单元32处于未导通的状态，即出料孔11和导料胶管50互不相通；而在进行按压操作后，套管33会带动泵料单元32进行下移，并且使得泵料单元32变为导通状态，即实现了出料孔11与导料胶管50的导通。
具体的，此实施例泵料单元32的开闭控制结构如图1、图3和图4所示，此时的泵料单元32包括泵料活塞321和泵料管322；泵料活塞321以可进行活塞运动的方式安装于活塞缸壳31内，泵料活塞321上设有定位管323，定位管323贯穿泵料活塞321，定位管323活动套接于套管33内；泵料管322活动穿插于定位管323内，泵料管322的一端固定套接于套管33内，泵料管322的另一端封闭形成挡块324，挡块324密封遮挡定位管323的端口，泵料管322邻近挡块324的周壁上设有泵料孔325，泵料孔325导通泵料管322的内外；塑料按压头10的按压用于控制泵料孔325移动至活塞缸壳31内。
如图3所示，此时未进行按压操作，所以泵料孔325将置于定位管323围闭的空间内，使得全塑泵无法实现出料；且如图3所示，在未进行按压操作时，套管33的下端面与泵料活塞321相互分离，从而使得在进行按压操作时，套管33具有一定的下移空间，所以如图4所示，在进行按压操作后，泵料孔325将下移至定位管323围纳的空间外，然后套管33的下端将会与泵料活塞321抵接，从而推动泵料活塞321下移，以此将活塞缸壳31的物料流经泵料孔325输出。
如图3和图4所示，此实施例优选设置活塞缸壳31的壳壁上设有回气孔311， 回气孔311导通活塞缸壳31的内外，回气孔311设于活塞缸壳31邻近导向孔23的一侧；处于初始位置的泵料活塞321遮盖回气孔311。
在采用此设置方式后，则可利用回气孔311实现活塞缸壳31内的压差平衡调控，从而确保在进行按压操作后，各部件能够自动迅速复位至原位。
如图3至图5所示，此实施例优选设置活塞缸壳31内设有单向阀60，单向阀60包括胶环61、弹性胶膜62和软胶连接筋63；胶环61内设有弹性胶膜62；弹性胶膜62遮蔽导料胶管50与活塞缸壳31的连接导通处；多根软胶连接筋63连接于胶环61内周壁与弹性胶膜62的外周缘之间。
在未产生压差变化时，弹性胶膜62会完全遮蔽导料胶管50与活塞缸壳31的连接导通处，所以物料将无法进入至活塞缸壳31内；而在通过按压操作导致活塞缸壳31内产生压差变化后，弹性胶膜62将会产生形变，从而解除对导料胶管50与活塞缸壳31连接导通处的遮蔽，所以物料将可进入至活塞缸壳31内，以此实现物料的单向输入。
如图3和图4所示，此实施例优选设置活塞缸壳31外套有垫圈70。
在采用此设置方式后，将可利用垫圈70增强全塑泵日后装配后的密封性。
如图1至图4所示，此实施例优选设置塑料复位弹簧40为管状。
在采用此设置方式后，则可使得塑料制成的弹簧也具备较佳的形变恢复能力。
当然，上述的全塑泵在实际应用过程中会与储料瓶组合应用，所以本发明还提供了一种单一材料的储料瓶，如图6所示，储料瓶80装配有上述的全塑泵，导料胶管50置于储料瓶80内，此时具备的功能与上文一致，故此不再叙述。
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。
