发明内容
本发明的主要目的，在于解决现有气泵虽具备有一电磁阀及一止回阀以控制气流，但仍无法避免一待充气物产生过度饱和的问题。

具体实施方式
本发明详细说明及技术内容，现就配合图式说明如下：
请参阅图1至图3，本发明提供一种具备外置式泄压阀的气泵100，该气泵100包含有一气泵本体10、一流道座20以及至少一气阀30，该流道座20设于该气泵本体10上，该气阀30接设于该流道座20上。具体说明，该气泵本体10包含一驱动马达11以及至少一受该驱动马达11作动并产生一输出气流的气囊组12，该气囊组12具有一排气孔121，该排气孔121连通该气囊组12并输出该输出气流，该驱动马达11及该气囊组12的实施方式可参照中国专利公告号CN 206290397U以及本申请人所提申之中国专利申请号CN 201810141741.X，于此不再赘述。另一方面，该流道座20上设有一接收该输出气流的气流通道21以及一连通该气流通道21并延伸至该流道座20任一侧壁面的泄压通道22。详细来说，请搭配图2与图3，该气流通道21一端连通该排气孔121，并于另端设有一供该输出气流排出的气流出口211，而该泄压通道22的设置位置于该流道座20上，且为使该泄压通道22可快速排出该输出气流，可令该泄压通道22设置于该气流通道21中央，并可朝该流道座20未设有该气流出口211的任一方向延伸。也就是说，该泄压通道22的延伸方向可根据使用需求进行调整，并不以图中所绘为限。此外，为使该泄压通道22可显露于该侧壁面上，该侧壁面上须开设有一流通该泄压通道22的装设孔23，并使一泄压组件24可由该装设孔23置入该泄压通道22内。再者，该至少一气阀30装设 于该流道座20上并连通该气流出口211以排出该输出气流对一待充气物充气。
承上述，并参图4及图5，为详细描述该泄压通道22，而将该泄压通道22区分为一接设段221、一活动段222以及一装设段223。一实施例中，该接设段221、该活动段222以及该装设段223的分别具有不同的内径，其中，内径大小顺序为接设段221<活动段222<装设段223。另一方面，更具体说明该泄压组件24，该泄压组件24包含有一设置于该装设段223内的固定件241以及一设置于该活动段222内并以一弹性件242抵接该固定件241的活动件243，详细地说，为使该固定件241装设于该装设段223上，并使该固定件241可同时方便使用者操作，而令该固定件241以螺接方式与该装设段223连接，也就是说，使用者可通过旋扭方式调整该固定件241。此外，该弹性件242的两端分别抵顶该活动件243及该固定件241，亦即该弹性件242受该固定件241作用，并且该弹性件242将推抵该活动件243。再者，该活动件243受该泄压通道22内压力变化作用而具有一封闭该接设段221的封闭位置以及一让该气流通道21内气流可由该接设段221排出的泄压位置。也就是说，于研制过程中，该活动件243外径须大于该接设段221内径，该活动件243才可完全封闭该接设段221避免该气流通道21内的气流外泄，除此之外，为使该活动件243可被置入该活动段222中，该活动件243的外径须被设定小于该装设段223以及该装设孔23的内径，于装配过程中令该活动件243可由该装设孔23进入。另外，一实施例中，该固定件241具有一连通该装设段223与外部的透气孔244，该透气孔244让泄压气流得排出至外部。再者，该透气孔244上覆盖有一透气件245，该透气件245可为一棉质材料。换句话说，于装配过程中，该透气件245将被设置于该固定件241上，而于实施过程中该透气件245令该输出气流得以朝外部排出。
承上，接着说明该泄压组件24的实施方式。于此首先假设该活动件243以该弹性件242受该气流通道21内压力变化而位于该封闭位置，如图5所示，另一方面，当该活动件243未受该弹性件242作用而位于该泄压位置即如图6所示。具体说明，为避免该气泵100对该待充气物过度充气，而可借由该固定件241装设于该装设段223上的旋紧程度对该弹性件242施以作用，进而限制该输出气流的压力，也就是说，该输出气流的气体压力可借由该固定件241进行调整，并且该气体压力不得大于该弹性件242施加于该活动件243的推抵作用力，换句话说，该气体压力的最大值将等于该弹性件242被压缩的程度，而 该弹性件242被压缩的程度决定于该固定件241作用于该弹性件242的作用力大小。承此，首先调整该固定件241作用于该弹性件242的作用力大小，并由该驱动马达11及该气囊组12产生该输出气流，该输出气流沿该气流通道21输出至该泄压通道22。当该气压值小于该弹性件242施加于该活动件243的该推抵作用力时，该活动件243将处于该封闭位置，此时该接设段221将被封闭而令该输出气流仅从该气流出口211排出。此后，当该气泵100持续工作，使该气体压力持续增加，一旦该气体压力大于该弹性件242施加于该活动件243的推抵作用时，该活动件243将由该封闭位置朝远离该接设段221方向位移。此时，该接设段221将由封闭转变为开放，部分的该输出气流将由该接设段221通过并自该装设孔23排出外部，进而可降低该气流通道21内的该气体压力。一旦该气体压力降至小于该弹性件242施加于该活动件243的该推抵作用力时，该活动件243将复归至该封闭位置。
本发明借由该固定件241设于该装设孔23上，令使用者可轻易操作该固定件241，借由调整该固定件241对该弹性件242所施予的作用力大小，而决定该弹性件242推抵于该活动件243的作用力，以调整该输出气流的压力。本发明相较于习知气泵，令该气泵100设有该泄压通道22，且该泄压通道22可向该侧壁面延伸，而使该泄压组件24可显露于该气泵100。通过本发明可令每一该气泵100分别对应不同的该待充气物，同时令装配人员可轻易于装配过程中调整该气泵100的压力，以因应不同的该待充气物所须的该气体压力。
一实施例中，复请参阅图5及图6，于实施过程中，为使该活动件243于该封闭位置时，可更确实封闭该接设段221，防止该输出气体外泄，而令该泄压组件24更包含有一止气件247，该止气件247设置于该活动件243与该接设段221之间，辅助封闭该输出气流通过。其中，该止气件247的外径须大于该接设段221的内径，惟须小于该装设段223的内径，如此才可将该止气件247置入该活动段222中，同时令该止气件247密封该接设段221。也就是说，于装配过程中，装配人员须首先将该止气件247置入该活动段222中封闭该接设段221，随后再置入该活动件243以完成装配。另外，于实施过程中，该活动件243因该气流压力而位于该泄压位置时，该止气件247亦会因该气流压力而朝远离该接设段221位移，当该气流压力降低时，该止气件247亦随该活动件243复归并再度封闭该接设段221。
一实施例中，复请参阅图2及图3，为确实覆盖该透气件245于该透气孔244上，该固定件241可设有至少一限位臂246，于装配过程中，装配人员可利用该限位臂246固定该透气件245，并且于实施过程中防止该透气件245脱落。
一实施例中，请参阅图1，为加强该流道座20与该气泵本体10的组接强度，该流道座20上可设有至少一扣接件25，该扣接件25用以加强该流道座20与该气泵本体10的组接强度，防止该气泵100于使用过程因气体所产生的震荡而使该流道座20与该气泵本体10分离。
另一方面，请参阅图1至图3，该流道座20更设有一用以容置至少一该气阀30的第一接设部26，该第一接设部26位于该气流出口211的位置，令该气阀30可组接于该第一接设部26上并接收由该气流出口211输出的该输出气流。更具体地说，该气阀30可以卡接的方式设置于该第一接设部26上，可令装配人员轻松接设该气阀30于该第一接设部26上，另外，当该气阀30须维修替换时，该维修人员亦可轻松替换该气阀30。除此之外，并请参阅图8，该气阀30更可设置有一消音件31，而令该气泵100泄气时，该气流可借由该消音件31使该气流方向转变，造成该气流缓冲，降低因该气流所产生的噪音。
承上述，该气阀30更可包含有一止回阀32，该止回阀32防止该气阀30对该待充气物充气时该输出气流逆流，进一步地，该止回阀32连接于该气阀30并与该第一接设部26卡接设置，更详细地说，该第一接设部26具有一限位块261，而该止回阀32上设置有一对应该限位块261设置的限位孔321。于装配过程中，当该气阀30装设于该第一接设部26上时，该限位块261将被塞入至该限位孔321内，以限位该气阀30，防止该气阀30从该第一接设部26上脱离。另一方面，该气阀30的设置数量可如图中所绘，以二该气阀30作为实施方式，亦可不依图中所示而根据使用需求进行调整。
请参阅图2，一实施例中，该气泵本体10上可设有一电线13，而该流道座20上更设有一用以提供电气信号给该驱动马达11及该气阀30的控制电路板27，也就是说，该电线13可用以提供该驱动马达11电力，令该驱动马达11得以运作，另一方面，该驱动马达11及该气阀30接受该控制电路板27的电气信号，以决定启闭该驱动马达11及该气阀30。更详细地说，该控制电路板27包含有至少一电气接脚271，该电气接脚271用以连接一埠，接受该埠所传递的电气控制信号。再者，为使该控制电路板27可稳固组接于该流道座20上， 而令该流道座20设有一容置该控制电路板27的第二接设部28。具体说明，该第二接设部28是面对该第一接设部26设置。
复请参阅图2，一实施例中，为保护该气阀30与该控制电路板27，该流道座20上设有一覆盖该气阀30与该控制电路板27的盖体29，该盖体29目的在于防止该气阀30及该控制电路板27因受力而断裂。进一步地，由于当该气阀30装设于该流道座20上时，该气阀30是为裸露状态，也就是该气阀30的两侧并不具有任何保护结构，因此该盖体29上更可设有多个支撑板291，该二支撑板291设置于该气阀30的两侧，防止该气阀30受到碰撞，更可同时限位该气阀30，避免该气阀30于实施过程中因该气泵100产生的震荡而使该气阀30位移。除此之外，为使该气阀30可对该待充气物充气，同时为方便该控制电路板27接线，该盖体29上更可设有至少一供该气阀30接设的输出孔292，以及一供该控制电路板27接设的接线孔293。其中，该盖体29设有该输出孔292主要目的为保护该气阀30上的出气嘴防止断裂。再者，该输出孔292及该接线孔293的样态只须符合该气阀30对该待充气物的充气需求以及方便该控制电路板27的接线目的，而无须以图中样态为限。另一方面，于装配过程中，该盖体29是被放置在该流道座20上，而为避免该盖体29从该流道座20上脱落，一实施例中，该第二接设部28上可设有一组接凸块281，而该盖体29上可设有一对应该组接凸块281的组接孔294。也就是说，当该盖体29被装设于该流道座20上时，该组接凸块281将被塞入至该组接孔294内。另外，该组接孔294与该组接凸块281的设置位置并不以图中为限。
