具体实施方式
请参阅图1至图5，本发明提供一种气动泵，包括一隔膜件载体1、一隔膜件2、一阀膜件座体3、一阀膜件4、一端盖5、一驱动装置6及一过压保护阀7。
该隔膜件载体1可用以容纳及承载隔膜件2。该隔膜件2设置于隔膜件载体1上，该隔膜件2由弹性材料(如橡胶)制成，隔膜件2包含多个连动部21，所述连动部21从隔膜件2的一面往远离阀膜件座体3的方向延伸， 所述连动部21连接于驱动装置6，以便透过该驱动装置6驱动所述连动部21动作。在本实施例中，该驱动装置6包含一马达61及一传动件62，该传动件62连接于马达61及隔膜件2的所述连动部21之间，当驱动马达61转动时，可通过传动件62传动所述连动部21，使该隔膜件2动作。
该阀膜件座体3设置于隔膜件载体1的一端，使隔膜件2设置于隔膜件载体1与阀膜件座体3之间，隔膜件2与阀膜件座体3之间形成一泵腔室22，随着该隔膜件2的动作，泵腔室22的容积得以变化。
该阀膜件4设置于阀膜件座体3上，该阀膜件4由弹性材料(如橡胶)制成。该阀膜件4及阀膜件座体3组合形成一阀组件，该阀膜件4由弹性材料制成，阀膜件4大致呈平板状。该端盖5盖置于阀膜件座体3及阀膜件4上，且可将隔膜件载体1、阀膜件座体3及端盖5之间以螺栓或扣具等固定件予以固定。阀膜件4、阀膜件座体3及端盖5经配置，可允许空气进入泵腔室22，空气可通过泵腔室22输出，同时可以防止空气逆向流动。所述防止空气逆向流动可利用设置现有的单向阀等构件，由于其属于现有技术，且非本发明要求的重点，故不予以赘述。
该过压保护阀7设置于端盖5内，该过压保护阀7包含一弹簧71及一密封垫72，该端盖5内形成一弹簧腔51，该弹簧71设置于端盖5的弹簧腔51内。该密封垫72由弹性材料(如橡胶，热塑性塑胶)制成，弹簧71的一端可抵触于密封垫72，弹簧71能顶推密封垫72，使密封垫72朝向阀膜件座体3及阀膜件4的方向移动，该密封垫72可对应于阀膜件座体3及阀膜件4的中心部位。所述泵腔室22、阀膜件座体3、阀膜件4及端盖5之间形成一出气通道100，使空气可通过出气通道100向外输出。该出气通道100与过压保护阀7、弹簧腔51形成分隔的设计，亦即出气通道100与过压保护阀7、弹簧腔51不相连通。该出气通道100的一端可通过管路连接到车辆座椅的座椅气囊(图略)，以便对车辆座椅的座椅气囊进行充气的操作。
在本实施例中，该端盖5采用两件式设计，可包含一内盖体52及一外盖体53，该外盖体53盖置于内盖体52上，该弹簧腔51可形成于内盖体52及外盖体53之间，端盖5的内盖体52内形成有进气腔522，进气腔522与弹簧腔51相通。该密封垫72具有一中心部721及一外环部722(如图8及图9所示)，外环部722间隔的设置于中心部721的外侧，中心部721及外环部722之间连接有多个肋条723。该外环部722的外侧具有两定位孔724，且该内盖体52具有两定位柱54，两定位孔724配合于两定位柱54，使密封垫72得以设置于内盖体52上。
该中心部721具有一凸柱725，该凸柱725为带伞形球柱，该凸柱725上套设一弹簧固定座73，使弹簧固定座73固定在带伞形球柱的密封垫72 上。弹簧71的一端固定于弹簧固定座73，弹簧71的另一端抵触于适当的位置，使得弹簧71的一端可通过弹簧固定座73抵触于密封垫72。该中心部721及外环部722靠近内盖体52的一面可分别凸设一密封圈726及凹设一卡槽727，该密封圈726可抵触于内盖体52，用以增加密封垫72的中心部721的密封性。该卡槽727可卡接于内盖体52上一相对应的卡体521，使得密封垫72得以准确的定位于内盖体52上，同时也能减少密封垫72及内盖体52松动的风险。
所述泵腔室22、阀膜件座体3、阀膜件4及端盖5之间形成一气流通道200及一回流通道300。该密封垫72设置于气流通道200及回流通道300之间，亦即该密封垫72可设置于气流通道200远离泵腔室22的一端，该气流通道200远离泵腔室22的一端形成一密封口201，该密封口201可设于端盖5上，亦即密封口201可设于端盖5的内盖体52上。该端盖5可具有多个回流口301，所述回流口301位于回流通道300及密封口201之间，且所述回流口301与回流通道300及密封口201相连通。密封垫72在常态下(泵腔室22中的压力未超过预定的极限值时)盖置于该密封口201上，亦即密封垫72的中心部721在常态下盖置于该密封口201上，用以封闭该密封口201，使气流通道200呈封闭状，使气流通道200及回流通道300之间形成阻隔。该密封圈726可抵触于内盖体52上的密封口201外围处，用以增加密封性。
是以，泵腔室22内的空气在常态下只能通过出气通道100向外输出，只有在泵腔室22中的压力超过预定的极限值时，空气方可通过气流通道200顶推密封垫72，使密封垫72开启密封口201，此时气流通道200中的空气即可通过密封口201及所述回流口301输送至回流通道300中，以便进行泄压的动作。
本发明可利用驱动装置6驱动隔膜件2动作，借以调节泵腔室22容积，容积扩大时，将空气从周围环境吸入到泵腔室22中，在容积缩小时，将空气从泵腔室22中排出，通过出气通道100将空气输出(如图4及图5所示)，以便通过管路将空气输送至座椅调节装置的流体腔室，借由控制座椅气囊加以改变座椅提供用户倚靠区域的轮廓。当泵腔室22中的压力超过预定的极限值时，过压保护阀7的密封垫72可压缩弹簧71，使气流通道200开启(如图6及图7所示)，亦即使密封口201开启，以便进行泄压的动作，使空气不会完全通过出气通道100输出，此时部分空气即可通过气流通道200及回流通道300回流到进气腔522，用以避免车辆座椅的气囊在负载压力过高时气囊爆破。回流的空气亦可再次吸入到泵腔室22中，以便通过出气通道100将空气输出，提升气动泵的工作效率。
本发明的特点及功能在于：
本发明可利用驱动装置驱动隔膜件动作，借以调节泵腔室容积，在容积缩小时，将空气从泵腔室中排出至外部空间，可通过出气通道将空气输出。本发明进气腔与过压保护阀泄压弹簧腔相通，避免过压保护阀直接泄压到大气时产生的噪音，同时泄压后的气流被再次利用，提升了气动泵的工作效率。
以上所述仅为本发明的优选实施例，非意欲局限本发明的专利保护范围，故凡是运用本发明说明书及附图内容所作的等效变化，均同理皆包含于本发明的权利保护范围内。
以上所述仅为本发明的较佳可行实施例，凡依本发明申请专利范围所做的均等变化与修饰，皆应属本发明的涵盖范围。
