相关申请的交叉引用
本申请要求于2018年02月01日提交中国专利局的申请号为2018101044217、名称为“充气泵”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及充气装置技术领域，尤其是涉及一种充气泵及其工作方法和应用。
背景技术
目前，充气产品由于其携带方便，便于收藏的特点，越来越受消费者的欢迎。现有技术中的充气床摆脱了传统床垫笨重的缺点，室内室外都可以随意的放置，放气后体积小，便于携带和收藏，适用于普通居家、家里来客临时铺床、办公室午睡和旅游露营等。随着充气床的产生也使得为其充气泄气的装置也进入了市场。
现有技术的充气装置一般主要包括气压泵、气压泵开关的充气阀门。充气的时候按动开关，气压泵开始工作，气体从充气阀门进入到充气床内部，充气完成后按动开关，气压泵停止，充气阀闭合，完成充气过程。排气的时候，按动开关，阀门打开，气压泵开始工作，将气体从气床内部抽出。
由于是手动的控制充气放气过程，使用者在选择充气或放气的旋钮后，需在旁等待气床充气到满意的状态时手动的旋动旋钮停止继续充气。有时在充气的过程中使用者忘记关气泵开关，而气床还在继续的充气，这样会导致充气床充坏。

图1为本申请实施例提供的充气泵的爆炸图，如图1所示，本申请实施例提供的充气泵包括：壳体1、控制机构和充气机构，控制机构和充气机构均设于壳体1内；控制机构包括压力感应器和控制线路板2，压力感应器与控制线路板2信号连接，控制线路板2与充气机构信号连接，压力感应器通过第一通气管与壳体1的外部连通，充气机构通过设于壳体1上的进气口110与壳体1的外部连通。
进一步的，控制机构还包括旋钮3和弹片盖4，旋钮3与弹片盖4固定连接，弹片盖4上设有与控制线路板2接触的金属片，控制线路板2上设有多个触点，旋钮3可带动弹片盖4转动，以使金属片与不同的触点接触，以对不同档位的压力进行设置。
如图1所示，壳体1的开口处盖合有面板120，面板120上设有通风口，通风口用于外部气体进入充气泵，或使充气泵内的气体排出外部；旋钮3设于面板120上，面板120上具有充气档位、关闭和放气的标志，旋钮3上设有标示线；旋钮3与弹片盖4通过螺钉固定连接，弹片盖4上的金属片与控制线路板2上的触点接触，每个触点对应压力感应器一个压力值。旋转旋钮3，标示线与相应档位的标志相对，金属片与相应档位的触点接触，控制线路板2将压力设定值信号传输至压力感应器，当压力感应器感应到被充气物内的压力达到设定值，将信号传输至控制线路板2，控制线路板2使充气机构停止充气。通过旋钮3控制充气的档位，实现了无极调档。
进一步的，控制机构还包括单向阀和推动组件，单向阀设于进气口110；旋钮3与推动组件传动连接，旋钮3通过推动组件控制单向阀的开启和关闭。
如图2所示，单向阀通过支撑座51安装于壳体1上，单向阀的单向阀片5位于支撑座51的背离壳体1的一侧，支撑座51上设有通孔,单向阀片5由橡胶材料制成,并覆盖于通孔上；单向阀的阀杆穿过支撑座51，且阀杆与支撑座51上的推杆固定连接，推杆远离单向阀的一端与推动组件连接，推杆上套设有螺旋弹簧52。
在充气过程中的气体使单向阀片5变形,气体通过支撑座51上的通孔进入被充气物；放气过程中，旋钮3带动推动组件运动，推动组件推动推杆向靠近单向阀片5的方向运动， 推杆推动单向阀向壳体1的外部运动，从而单向阀打开，同时，螺旋弹簧52处于压缩状态；当控制机构回复至原位时，在螺旋弹簧52回复力的作用下，单向阀向壳体1的内部运动，单向阀关闭。推动组件和单向阀的设置，可通过旋钮3控制进气口110的开启和关闭。
进一步的，推动组件包括拨动盘6、槽轮7和转换器8，旋钮3与拨动盘6固定连接，槽轮7与转换器8固定连接，拨动盘6与槽轮7配合，转换器8与单向阀相对设置，且转换器8上设有与单向阀配合的开关结构；旋钮3通过拨动盘6驱动槽轮7带动转换器8绕槽轮7的轴线转动，转换器8通过开关结构控制单向阀的开启和关闭。

当旋钮3处于关闭状态时，两个拨动柱与两个拨动槽一一配合，开关结构使单向阀处于关闭状态，自充气泵的外部向面板120看去，旋转旋钮3按图1所示的顺时针方向转动至低档时，弹片盖4和拨动盘6的转向与旋钮3的转向相同，同时，拨动盘6拨动槽轮7逆时针转动，并且，拨动柱与拨动槽分离，槽轮7带动转换器8转动，充气泵中的气体使单向阀片5变形，使充气泵中的气体通过进气口110进入被充气物；继续旋转旋钮3至中档，弹片盖4和拨动盘6跟随旋钮3转动，槽轮7和转换器8不转动，单向阀继续打开，控制线路板2改变压力感应器的感应压力设置；继续旋转旋钮3至高档，弹片盖4和拨动盘6跟随旋钮3转动，槽轮7和转换器8不转动，单向阀继续打开，控制线路板2改变压力感应器的感应压力设置。关闭充气泵时，旋钮3逆时针转动，当旋钮3转动至低档时，拨动盘6与槽轮7配合，拨动盘6带动槽轮7和转换器8逆时针转动，槽轮7和转换器8回复至原位，单向阀关闭。
需要说明的是，具体地，关闭充气泵时，旋钮3从充气档位逆时针旋转至关闭档位，同时槽轮7和转换器8顺时针旋转，此时单向阀是关闭状态；关闭充气泵时，旋钮3从放气档位(此时单向阀是推开状态)顺时针旋转至关闭档位，同时槽轮7和转换器8逆时针旋转，单向阀回位原始状态(即单向阀是关闭状态)。需要强调的是，旋钮3旋至充气档位(低档，中档，高档)，或是关闭档位时，单向阀是原始位置，没有推开单向阀(进气是通过气体把单向阀片5吹变形，即可把气体进入充气物体内)；旋钮3旋至放气档位时，单向阀是推开状态，此时气体从内部往外排出。
旋转旋钮3按图1所示的逆时针方向转动至放气时，弹片盖4和拨动盘6的转向与旋钮3的转向相同，控制线路板2改变压力感应器的感应压力设置，同时，拨动盘6拨动槽轮7顺时针转动，并且，拨动柱与拨动槽分离，槽轮7带动转换器8转动，转换器8上的 开关结构使单向阀打开，被充气物中的气体通过充气泵排放至大气中，当被充气物内的压力达到放气压力时，停止放气。
进一步的，开关结构包括设于转换器8外周的弧形凸起81，单向阀的一端与转换器8的圆周面接触，且位于弧形凸起81的一侧。

需要说明的是，本申请实施例提供的充气泵的工作方法为，即使用本申请实施例提供的充气泵给物体充气时，进气口110和第一通气管均与被充气物体的内部连通，充气机构使气体通过进气口110进入被充气物体，同时，压力感应器感应被充气物体内的压力，当检测到被充气物体内的压力达到预设值时，压力感应器将信号传送至控制线路板2，控制线路板2控制充气机构停止充气，防止对被充气物体造成损坏。
本申请实施例还提供一种上述充气泵的应用，具体地是将本申请实施例提供的上述充气泵应用于充气床中。具体的，该应用包括：将壳体1设置于充气床内部，使进气口110和壳体1上的通孔均位于充气床的内部；对面板120与充气床进行固定连接，使旋钮3位于充气床的外部，通过旋钮3设置对充气床的充气压力，或对充气床进行放气；使用充气床过程中，压力感应器实时感应充气床内的压力，并通过泄气阀13和补气泵14调整充气床内的压力。
需要强调的是，在其它实施当中，并不仅限于本申请实施例所介绍的充气泵在充气床中的这一种应用，其还可以将充气泵应用于其它充气产品中，如充气枕垫，充气式凳子等。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方 案的范围。
工业实用性
本申请提供的充气泵及其工作方法和应用，缓解了现有技术中的充气泵达到充气要求后需手动关闭气泵的技术问题，因此，本申请具有重要的推广应用价值。
