实施例1：
本实施例提供了一种微型充气泵壳体结构，如图1和图2所示，包括泵壳体110和盖板111、进气口112、出风口115和隔板120。其中，泵壳体110内设有中空的内腔117，进气口112设于泵壳体110的上端面，出风口115设于泵壳体110的侧端面，隔板120位于内腔117中且将内腔117分隔成叶轮仓和控制仓，进气口112和出风口115都和叶轮仓贯通，形成气体流道。泵壳体110还设有一适于装配内部件的开口，开口处对应设置有可拆卸的组装的盖板111。开口可设置于泵壳体110的侧端面，也可设置在泵壳体110的底端面，本实施例中的微型充气泵壳体结构将开口设置于泵壳体110的底端面。
参考图8，泵壳体110的造型可以采用例如但不限于圆柱体或方柱体造型。
泵壳体110和盖板111的可拆卸式组装采用例如但不限于卡接式连接，具体地在泵壳体110底端面边缘设置适于盖板111上的卡接部(图中未示出)插接的卡接槽119，实现泵壳体110和盖板111的组装或拆卸。
参考图4和图5，泵壳体110的内腔117的壁上设有用于对隔板120进行组装定位的定位孔柱(图中未示出)，通过在隔板120对应于定位孔柱的位置开设的螺孔127，采用螺钉插入螺孔127和对应的定位孔柱中实现将隔板120固定安装于泵壳体110中。隔板120能够通过泵壳体110上设置的开口进出内腔117。
参考图4和图5，为了便于本微型充气泵的其它的内部配件组装于隔板120的上、下端面，隔板120上开设有一通孔125。
需要进一步说明的是，在本实施例中泵壳体110采用一体成型的工艺制造而成，这样有助于减少微型充气泵壳体结构在外观上的组装痕迹，使得外形更加美观。
本实施例提供的微型充气泵壳体结构，通过在泵壳体110内配置的一隔板120，将内腔117分隔成叶轮仓和控制仓，便于不同的内部配件分别组装于隔板120的上、下端面，即只要实现隔板120和泵壳体110的组装即可完成整体的微型充气泵的组装，提高了组装的便捷性。微型充气泵壳体结构在外观减少了组装痕迹，使得外形美观，整体结构小巧轻便，便于携带和使用。
实施例2：
本实施例提供了一种微型充气泵，如图5至图8所示，同时参考图3，该微型充气泵包括实施例1中提供的微型充气泵壳体结构，以及电机150、叶轮组件、控制电路板和供电单元。其中，电机150位于微型充气泵壳体结构的控制仓内且其输出轴从隔板120上设置的通孔125处插入叶轮仓中。叶轮组件位于叶轮仓内，与电机150的输出轴相连且适于由电机150的输出轴控制转动。控制电路板，位于控制仓内且与电机150电连接，适于控制电机150工作，即控制电路板控制电机150工作进而带动叶轮组件转动。供电单元，与控制电路板电连接，为控制电路板和电机150供电。
控制电路板包括单片机130和与单片机130电连接的过流保护电路。通过设置的过流保护电路，当主电路的电流超过额定电流时候，过流保护电路自动断电，以保护微型充气泵不被烧坏。
微型充气泵还包括与单片机130电连接的开关按钮，通过按压开关按钮，能够控制电机150开启或关闭。具体的，泵壳体110的内腔117的壁上开设有与开关按钮137相对的开关孔，该开关孔适于按动开关按钮137。且为了防止杂物灰尘进入泵壳体110，在开关孔处设置有柔性防尘塞(图中未示出)。通过按压柔性防尘塞，能够使柔性防尘塞与开关按钮137接触，从而触发开关按钮137，进而控制电机150开启或关闭。
电机150和控制电路板均固定在隔板120的下端面。具体的，电机150与隔板120之间通过螺钉连接。如图6，参照图4，为了便于安装单片机130，在隔板120的下端面设有一安装柱132。安装柱132垂直于隔板120，并与电机150间隔设置。控制电路板与安装柱132固定连接。控制电路板位于安装柱132与电机150之间。将控制电路板设置在安装柱132与电机150之间，能够加强对控制电路板的保护，降低控制电路板因外部冲击而损坏的概率。进一步的，在安装柱132上配置一通槽133使开关按钮137穿出安装柱132，上述的开关孔对应于安装柱132上的通槽133设置，从而便于操作按动开关按钮137。
参考图4，叶轮仓内还配置有围设于叶轮组件周缘的且与隔板120上端面连接的一挡圈板122。挡圈板122的侧端面开设有一适于与出风口115搭接的出风嘴123，挡圈板122的上端面的边缘抵顶于泵壳体110的内腔117壁。挡圈板122和出风嘴123的配合提高了风从出风嘴123往出风口115的风力的聚合性。叶轮组件的上端面低于挡圈板122的上端面， 便于叶轮组件的正常运转。
可选的，如图7所示，过流保护电路包括保护芯片U1，连接于保护芯片U1的控制管脚、开关管U2以及敏感电阻RS。开关管U2和敏感电阻RS共同串联于保护芯片U1的保护支路上，敏感电阻RS的两端连接于保护芯片U1的测量管脚。开关管U2用于导通或断开保护支路。保护芯片U1根据测量信号产生控制信号。
本领域技术人员可以理解的是：保护芯片U1不仅可以通过测量电压，计算电流并比较阀值来产生控制信号，还可以测量温度等物理信号的方式来产生控制信号。也即，敏感电阻RS为压敏电阻、热敏电阻、光敏电阻、湿敏电阻、磁敏电阻和气敏电阻中的一种或多种。保护芯片U1的管脚测量对应的物理信号并在达到预定阀值时产生控制信号。本实施例以敏感电阻RS为压敏电阻，通过测量电压，计算电流后比较阀值产生控制信号为例进行说明。通过设置的敏感电阻RS，增强过流保护电路的滤波效果，减小了空间损耗，同时达到了过流保护阀值精确，安全性好，电源寿命长的技术效果。
保护芯片U1的测量管脚包括管脚VM和管脚VSS，管脚VM串联电阻R2后连接于敏感电阻RS的管脚1和开关管U2的管脚S2及管脚S2’，管脚VSS连接于敏感电阻RS的管脚2和端口B-；保护芯片U1的测量管脚包括管脚DO和管脚CO，管脚DO连接于开关管U2的管脚G2，管脚CO连接于开关管U2的管脚G1。
过流保护电路还包括电阻R1、电容C1、电容C2A、电容C2B、电容C3、电容C4及电阻R3。其中，电阻R1的管脚1连接于端口B+、端口P+及电容C4的管脚1，管脚2连接于电容C1的管脚1、保护芯片U1的管脚VDD；电容C1的管脚2串联电容C2A、电容C2B后连接于开关管U2的管脚S1、管脚S1’、电容C3的管脚2、电阻R3的管脚2及端口P-；电容C3的管脚1串联电容C4后连接于端口B+、电阻R1的管脚1及端口P+；电阻R3的管脚1连接于端口NTC。
开关管U2采用例如但不限于MOSFET管。
过流保护电路集成于设置于控制仓内的一电路板上，其供电电源为本实施例中的供电单元。
本实施例中的供电单元包括可充蓄电池(图未示出)。可充蓄电池位于控制仓内，其额定电压设定为直流3.7V。微型充气泵还包括与可充蓄电池电连接的输入电压转换电路(图未示出)以及与输入电压转换电路电连接的USB输入接口139。USB输入接口139设置于泵壳体110上。可充蓄电池通过USB输入接口139进行充电。USB输入接口139额定电压为5V，5V电源充电器是最普遍的手机电源充电器，可随时随地对可充蓄电池进行充电，减少充电器选择的局限性。通过设置的输入电压转换电路，该输入电压转换电路主要由转换器构成，转换器用于将输入的5V电压，转换成3.7V输出。
具体的，为了保障满足使用的需求，本实施例中的可充蓄电池采用聚合物锂电池，且为了确保电量供给需求，优选设置为两块聚合物锂电池，在实际组装过程中，可直接将聚合物锂电池粘结于泵壳体110的内腔117的壁上，还可通过在隔板120的下端面配置锂电池固定板，实现将聚合物锂电池固定于隔板120上。
如图5，叶轮组件包括一旋转轴140和均匀分布于旋转轴140周缘的至少六片叶片142，可选设置为六片或者八片，可根据实际微型充气泵的大小设定具体的叶片142的数量。叶片142垂直连接于旋转轴140，垂直连接的方式便于加大从进风口进入的风量。以及叶片142包括一体成型的矩形部和位于矩形部上方的等腰梯形部。等腰梯形部的底边部与矩形部连接，即等腰梯形部的腰部结构和矩形部的结合进一步加大了风的旋转力，从而提高了出风口115的风量。
如图3，为了使本发明的微型充气泵适用于更多的产品需要，出风口115上安装有具有多个不同直径适配头162的适配件160。
为了当微型充气泵长时间使用时，电机150散发的热量能及时排除，可在控制仓对应的泵壳体110的内腔117壁设有若干散热槽(图中未示出)。
本实施例中的微型充气泵的组装过程如下：将电机150安装于隔板120的下端面，采用例如但不限于螺钉连接将电机150予以固定，且使电机150的输出轴穿过隔板120的通孔125。再将叶轮组件的旋转轴140与电机150穿入叶轮仓的输出轴部分固定连接，使电机150的输出轴带动叶轮组件的旋转轴140转动。再将控制电路板固定在安装柱132上。完成上述步骤，将隔板120置入泵壳体110的内腔117中，通过泵壳体110的内腔117壁设有的用于对隔板120进行组装定位的定位孔柱，采用例如但不限于螺钉将隔板120固定安装于泵壳体110中。再将聚合锂电池通过粘结件例如但不限于双面胶使聚合锂电池固定于泵壳体110的内腔117壁上。最后将盖板111盖合在泵壳体110的下端面，即可完成整体的微型充气泵的安装。
本实施例提供的微型充气泵，通过在泵壳体110内配置的一隔板120，将泵壳体110的内腔117分隔成叶轮仓和控制仓，便于不同的内部配件分别组装于隔板120的上、下端面，即只要实现隔板120和泵壳体110的组装即可完成整体的微型充气泵的组装，提高了组装的便捷性，同时也便于拆卸维修。
以上仅为本发明的优选实施方式而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
