具体实施方式
下面结合具体实施例，进一步阐述本发明。应理解，这些实施例仅用于说明本发明而不用于限制本发明的范围。此外应理解，在阅读了本发明讲授 的内容之后，本领域技术人员可以对本发明作各种改动或修改，这些等价形式同样落于本申请所附权利要求书所限定的范围。
本发明的实施方式涉及一种采用锥形阀片的充气泵，如图1-5所示，包括泵体1、进出气阀板2和进出气端面板3，所述的泵体1的内部竖向布置有上下运动的活塞杆6，该活塞杆6的上端安装内孔中安装有偏心轮5，该偏心轮5与外部的电机相连，所述的活塞杆6的下端安装有周边与侧壁紧贴的皮碗7，所述的进出气阀板2安装在泵体1的下端，所述的进出气阀板2上并排开有通孔，两个通孔的周围分别均匀布置有若干个进气孔14和排气孔13，所述的进气孔14的上端布置有底面呈圆锥面的进气阀槽12，该进气阀槽12内安装有插入到通孔内并将进气孔14盖住的进气阀片10，所述的排气孔13的下端布置有底面呈圆锥面的排气阀槽11，所述的排气阀槽11内安装有插入到通孔内并将排气孔13盖住的排气阀片9，所述的进出气端面板3内布置有进气孔14和排气孔13相对应的排气腔16和侧面开孔的进气腔17，所述的进出气端面板3的侧壁安装有与排气腔16相通的排气连接管4。
外部的电机通过转轴带动偏心轮5快速转动，偏心轮5快速转动转化为活塞杆6的上下移动，实现将空气吸入并将高压气体排出，皮碗7能保证活塞杆6的底部与进出气阀板2之间形成密闭的空间。
本发明采用呈环形布置的多个进气孔14和排气孔13有利于进气和排气的顺畅，而进气阀片10与圆锥形的进气阀槽12向贴合，使其中部固定不动，而四周上翘，上翘的幅度不大，有一定的负压就可以将外部的空气吸入到活塞腔中，吸入后能快速回复，防止进气出现紊乱的情况。
同理，排气阀片9与排气阀槽11向贴合，使其中部固定不动，而四周上翘，上翘的幅度不大，活塞挤压的高压气体可以很轻易地将排气阀片9的四周部分冲开，而冲开后由于阀片具有弹性，所以很快就会回复将进气孔14密封，不会产生返流。
进一步的，所述的活塞杆6的下端安装有压盘8，所述的皮碗7夹在压盘8和活塞杆6之间，保证皮碗7的稳定安装，皮碗7只需要启到密封作用就可以了。
进一步的，所述的排气阀槽11的底面锥度大于进气阀槽12的底面锥度， 由于排气阀槽11处对应的是高压气体，所以其锥度要大一些，保证阀片能快速回位。
进一步的，所述的泵体1的下端通过环形连接部15与进出气阀板2相连，所述的皮碗7的侧边与环形连接部15的内侧壁紧贴，方便组装和拆卸泵体。
进一步的，所述的进气腔17的底面布置有若干散热凸起筋18，启到较好的散热效果和气流导向作用，提高进气的效率。
进一步的，所述的进出气端面板3的底部均匀布置有若干个散热凸起筋18，由于有进出气端面板3内的气体进出比较快速，产生了比较多的空气摩擦，热量较大，散热凸起筋18能使其使用的时候快速散热。
进一步的，所述的排气连接管4为并排布置的两根气管接头，两根气管接头的直径尺寸不同，适用于不同直径的充气管。
本发明所述的充气泵采用锥形阀片，由于阀片四周翘起，中部内凹，进气和排气的时候很容易打开，而且进排气完成后能利用阀片的弹性来快速密封进气孔和排气孔，有效防止高压气体的返流，保证直驱的充气泵能正常的启动，解决了原来直驱的充气泵都无法解决的技术问题，有利于直驱的充气泵的推广。
