在本发明的一个实施例中，参照图1和图2，提供一种机械式气泵，包括驱动机构100、气体发生器和200和流量加速器300。
参照图1和图2，驱动机构100上设有壳体400，壳体400内具有腔体410，壳体400外壁设有连通腔体410的进气口420和出气口430。
参照图1和图2，气体发生器200和流量加速器300均安装于腔体410，驱动机构100驱动气体发生器200和流量加速器300运转。
参照图1和图2，气体发生器200将外界气体从进气口420吸进腔体410内，流量加速器300对腔体410内的气体进行加速以形成高速高压气体，并从出气口430输出，实现充气，无需采用多个隔膜式皮碗进行反复拍打执行充气的方 式，机械式气泵在运作时，具有噪音小，震动小，磨损小，使用寿命长等优点。
在本发明的另一个实施例中，参照图1和图2，腔体410的中部设有一隔板440，隔板440将腔体410分成上腔体411和下腔体412。气体发生器200和流量加速器300分别安装于上腔体411和下腔体412，隔板440至少贯穿设有一通气孔441。出气口430与上腔体411连通，进气口420与下腔体412连通。气体发生器200将外界气体依次经过进气口420、下腔体430和通气孔441而进入上腔体411，然后经流量加速器300对上腔体411内的气体进行加速以形成高速高压气体。
在本发明的另一个实施例中，参照图1和图2，气体发生器200包括至少一转动轴210。转动轴210的第一端转动连接于腔体410内的隔板440中部，转动轴210上至少设有一扇叶220，驱动机构100与转动轴210连接并驱动其转动，转动轴210带动扇叶220转动，从而带动外界气体依次经过进气口420、下腔体412和通气孔441而进入上腔体411。
进一步地，参照图1和图2，驱动机构100为电机，壳体400固定安装于电机的外壳上，电机的转动轴伸进下腔体412并与转动轴210的第二端固定连接。通过电机带动转动轴210转动，结构简单。
进一步地，参照图1和图2，转动轴210的第一端通过第一轴承(图未示出)转动连接于腔体410内的隔板440中部，使转动轴210转动流畅，安装稳定，噪音小。
进一步地，参照图1和图2，壳体400在扇叶220的四周均匀设有多个进气口420，通过多个进气口320同时进气，进气量大，且进气均匀，噪音小。
在其他实施例中，参照图1和图2，转动轴210由上至下排列设有多个扇叶220，多个扇叶220在转动时，吸力大，有利于将外界气体快速带动外界气体依次经过进气口420、下腔体412和通气孔441而进入上腔体411。
在本发明的另一个实施例中，参照图1和图2，流量加速器300包括主动螺旋杆310。主动螺旋杆310转动连接于腔体410，驱动机构100与主动螺旋杆310 连接并驱动其转动，主动螺旋杆310高速转动并推动气体快速流动，使气体沿主动螺旋杆310的螺旋槽311快速流动以形成高速高压气体，高速高压气体从出气口输出，气体流量输出大，且输出气压高。
具体地，参照图1和图2，主动螺旋杆310的第一端与转动轴210的第一端固定连接，通过转动轴210带动主动螺旋杆310转动，结构简单。
进一步地，参照图1和图2，流量加速器300包括两从动螺旋杆320。两从动螺旋杆320均转动连接于腔体410，两从动螺旋杆320分别位于主动螺旋杆310的相对两侧，且两从动螺旋杆320均与主动螺旋杆310啮合连接。
参照图1和图2，通过主动螺旋杆310带动两从动螺旋杆320转动，主动螺旋杆310和两从动螺旋杆320同时转动并推动气体快速流动，使气体沿主动螺旋杆310和从动螺旋杆320的螺旋槽快速流动以形成高速高压气体。同时，主动螺旋杆310与从动螺旋杆320相互啮合的螺旋槽能起到一定密封作用，防止气体扩散，使气体能沿着上述螺旋槽快速流动。
由于扇叶220、主动螺旋杆310和两从动螺旋杆320在工作时均为高速转动，能达到快速提升气体的流速，使得加速后的气体流量输出大，且输出气压高。
具体地，参照图1和图2，从动螺旋杆320的两端通过第二轴承(图未示出)分别与隔板440和上腔体411的顶壁转动连接，从动螺旋杆320安装稳定。还有，两从动螺旋杆320分别啮合连接于主动螺旋杆310的相对两侧，两从动螺旋杆320对主动螺旋杆310具有支撑作用，因此主动螺旋杆310的第二端可以不与上腔体411的顶壁相连(即悬空状态)，减少零件成本。
进一步地，上腔体411适配容置主动螺旋杆310和两从动螺旋杆320，上腔体411的内侧壁与主动螺旋杆310和两从动螺旋杆320外侧壁之间具有细小间隙，保证主动螺旋杆310和两从动螺旋杆320在高速转动时，不会与上腔体411的内侧壁产生摩擦，减小磨损。
进一步地，参照图1和图2，出气口430朝向主动螺旋杆310并与其轴线平行设置，经螺旋槽推动而加速流动的气体能快速从出气口430输出，上述出气 口430处于中心位置对气体阻力小，有利于高速高压气体输出。
在其他实施例中，参照图3，上腔体411靠近其顶部位置设有一安装板450，安装板450贯穿设有多个通孔451，上腔体411内的气体能穿过通孔451从出气口430输出。
其中，参照图3，从动螺旋杆320的两端通过第二轴承(图未示出)分别与隔板440和安装板450转动连接，主动螺旋杆310的第二端通过第三轴承(图未示出)与安装板450转动连接，使得主动螺旋杆310和两从动螺旋杆320安装稳定，在高速旋转时，不易晃动或震动，噪音小。
在本发明的另一个实施例中，参照图1和图2，通气孔441设有单向阀500，单向阀500具有单向导通的作用。在扇叶220旋转时，下腔体412内的气体能够推动单向阀500打开，并通过单向阀500进入上腔体411，在扇叶220停止旋转时，单向阀500在其自身弹簧的推动下复位而关闭，上腔体411内的气体无法通过单向阀500进入下腔体412，避免气体倒流，提高气体的利用率。其中，单向阀500为成熟的现有技术。
在本发明的另一个实施例中，参照图1和图2，壳体400的外壁设有连通腔体410的调压装置600，调压装置600用于调节上腔体411内的气压。当上腔体411内的气压大于调压装置600所设定的压力值时，上腔体411内的气体能通过调压装置600排除外界，保持上腔体411内的气压为设定气压，以适用不同的使用需求。
进一步地，参照图1和图2，调压装置600包括阀体610、密封件620、弹性件630和调节件640。阀体610安装于壳体400的外壁，阀体610贯穿设有连通腔体410的上腔体411的安装孔611，安装孔611靠近上腔体411的一端尺寸缩小形成启闭口612，密封件620、弹性件630和调节件640均安装于安装孔611，弹性件630弹性推顶密封件620密封抵接启闭口612，调节件640用于调节弹性件630的预紧力。
参照图1和图2，当上腔体411内的气压超过设定值时，气压会推动密封件 620并压缩弹性件630，使密封件620远离启闭口612，启闭口612打开，上腔体411内的气体通过安装孔611排除外界。当上腔体411内的气压等于或小于设定值时，弹性件630弹性推动密封件620密封抵接启闭口612，启闭口612处于关闭状态。
进一步地，参照图1和图2，安装孔611靠近外界的一端设有内螺纹，调节件640设有外螺纹，外螺纹与内螺纹适配连接。弹性件630的两端分别抵压密封件620和调节件640，因此，拧动调节件640可调节弹性件630的预紧力，从而实现调节上腔体411内部的气压，达到调压的效果，以适用不同的使用需求。
进一步地，参照图1和图2，密封件620设有球形部，启闭口612靠近密封件的一端圆锥形口612a，球形部适配抵接圆锥形口612a，连接紧密，密封效果好。
其中，参照图1和图2，弹性件630为弹簧，弹簧630的两端分别抵压密封件620和调节件640，结构简单，弹力稳定。
在其他实施例中，调压装置600为调压阀，使用方便，精度高。
因此，参照图1和图2，通过扇叶220吸进气体420以及主动螺旋杆310和从动螺旋杆320对气体进行加速的充气方式，相比于现有采用多个隔膜式皮碗进行反复拍打执行充气的方式，具有气体流量输出大，噪音小，震动小，磨损小，使用寿命长等优点。
本实施例的其余部分与实施例一相同，在本实施例中未解释的特征，均采用实施例一的解释，这里不再进行赘述。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，其架构形式能够灵活多变，可以派生系列产品。只是做出若干简单推演或替换，都应当视为属于本发明由所提交的权利要求书确定的专利保护范围。
