 本发明的实施方式
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。
本发明提供了一种双弹簧全塑真空泵，其实施例如图1和图2所示，包括基座10和按头20，基座10底部设有进料孔11，按头20与基座10装配围成容纳腔12，进料孔11与容纳腔12导通，容纳腔12内设有限位罩30、塑料单向弹簧40、出料件50和塑料复位弹簧60；限位罩30包围于进料孔11外，限位罩30的顶部设有导向孔31，导向孔31与限位罩30的内部导通；塑料单向弹簧40夹持于基座10与限位罩30之间，塑料单向弹簧40相对的两端分别为固定端41和受力端42，固定端41与受力端42相互导通，固定端41与进料孔11连接导通，受力端42与导向孔31导通；出料件50设于按头20与限位罩30之间，出料件50穿过导向孔31与受力端42导通，出料件50用于接料至按头20输出；塑料复位弹簧60夹持于出料件50与限位罩30之间；按头20的按压用于推动出料件50压缩塑料单向弹簧40。
在进行应用时，应将双弹簧全塑真空泵与瓶体70装配使用，此时瓶体70与基座10连接固定，瓶体70内部用于存储物料；若用户对按头20施压，出料件50将对塑料单向弹簧40和塑料复位弹簧60施压，从而使得塑料单向弹簧40和塑料复位弹簧60处于收缩状态，塑料单向弹簧40内的物料将会经出料件50送至按头20排出；待用户不再对按头20施压后，塑料单向弹簧40会自动恢复原状，并由于气压变化的原因，塑料单向弹簧40还会自动从瓶体70内抽取物料，直至物料将塑料单向弹簧40的内部填充饱满，而塑料复位弹簧60也会自动恢复原状，以此将按头20推回至初始位置。
所以此方案利用塑料单向弹簧40和塑料复位弹簧60取替了金属弹簧，在进行回收时，能够对泵头进行统一处理，从而切实解决了现有泵头不便于直接回收利用的问题。
如图1所示，出料件50包括出料管51和定位罩52；出料管51穿过导向孔31以插入至塑料单向弹簧40内，出料管51内部中空形成出料通道53，出料通道53与塑料单向弹簧40内部导通；定位罩52包围于出料管51的端部外周侧，定位罩52与出料管51外壁之间围成有环形槽54，塑料复位弹簧60的一端部嵌入环形槽54内。
在采用此结构后，塑料单向弹簧40的物料则可通过出料通道53输送至按头20排出，而且环形槽54也实现了塑料复位弹簧60上部的安装位置固定，从而为塑料复位弹簧60的工作稳定性提供了保障。
如图1所示，限位罩30的顶面设有一圈凸环32，凸环32包围于导向孔31外，塑料复位弹簧60的一端包围于凸环32外。
在采用此结构后，凸环32则实现了塑料复位弹簧60下部安装位置的固定，从而使得塑料复位弹簧60的工作稳定性得到进一步提高。
如图1所示，容纳腔12内还设有连接器80，连接器80包括相互连接的罩体部81和管体部82；罩体部81置于限位罩30内，受力端42设于罩体部81内，受力端42与罩体部81抵接；管体部82穿过导向孔31，以套于出料管51外。
即在用户对按头20施压后，出料件50能够带动连接器80一同下移，以此通过连接器80对塑料单向弹簧40施加向下的压力，从而实现塑料单向弹簧40的压缩控制；而在用户不再对按头20施压后，塑料单向弹簧40将带动连接器80一同复位。
如图1所示，管体部82与罩体部81的内部连接处设有往内收窄的限位壁83，限位壁83围成的空间与塑料单向弹簧40和出料通道53导通，限位壁83的最小直径小于出料管51的外径。
此时限位壁83大致围成倒置的锥形状，所以当出料管51往下移动时，出料管51将与限位壁83抵接，以便于推动连接器80进行下移。
如图1所示，出料管51包括相互连接的进料段511和出料段512，出料段512的端口外壁设有定位罩52，出料段512的外管径大于管体部82的内管径。
即随着出料管51的下移，出料段512将会与管体部82抵接，从而限制出料管51的继续下移，避免出现过度下移而无法复位的现象。
如图1所示，罩体部81内设有支承环90，支承环90嵌入受力端42内，受力端42夹持于支承环90与罩体部81围成的空间内。
由于支承环90与罩体部81围成的空间较小，所以两者能够对塑料单向弹簧40实现稳定夹持，避免塑料单向弹簧40产生不稳定的形变，从而为塑料单向弹簧40稳定压缩复位提供了保障。
如图1所示，基座10的底部内表面设有第一环形定位槽131，第一环形定位槽131包围于进料孔11外，固定端41嵌入第一环形定位槽131内；基座10的底部内表面还设有第二环形定位槽132，第二环形定位槽132包围于第一环形定位槽131外，限位罩30的下部嵌入第二环形定位槽132内；在采用此方式后，将可提高塑料单向弹簧40和限位罩30的安装稳定性。
如图1所示，双弹簧全塑真空泵还包括外罩100，外罩100以可拆卸的方式套于按头20外；即在需要使用时，拆除外罩100便可，无需使用时，则可以套上外罩100进行保护，从而避免物料被氧化。
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。
