The piston connecting rod assembly comprises a connecting rod, a piston ring and an air inlet valve, the connecting rod comprises a first end and a second end which are opposite, the first end is connected to an eccentric shaft, the second end is arranged in an air cylinder, and the piston ring and the air inlet valve are connected to the second end; the first end is conical, and the width of the first end is gradually reduced in the direction close to the eccentric shaft. The invention further discloses a supercharger which comprises an air pump and a motor, the air pump comprises a shell, four piston connecting rod assemblies and an eccentric shaft, the four piston connecting rod assemblies and the eccentric shaft are installed in the shell, four air cylinders are arranged in the shell, one end of each piston connecting rod assembly is movably arranged in the corresponding air cylinder, and the other end of each piston connecting rod assembly is connected to the eccentric shaft. The motor is connected with the eccentric shaft and used for driving the eccentric shaft to rotate so as to compress air. The four-cylinder small-stroke arrangement is adopted in the supercharger, and on the premise that the size is not increased, the exhaust noise can be effectively reduced.

    本发明公开了一种活塞连杆组件,包括连杆、活塞环和进气阀,连杆包括相对的第一端和第二端,第一端连接于偏心轴,第二端设置于气缸中,活塞环和进气阀连接于第二端;第一端呈锥形,第一端的宽度向着靠近偏心轴的方向逐渐减小。本发明还公开了一种增压机,包括气泵和电机,气泵包括壳体以及安装于壳体中的四个活塞连杆组件和偏心轴,壳体内设有四个气缸,各活塞连杆组件的一端可活动地设置于各气缸中,各活塞连杆组件的另一端连接于偏心轴,电机与偏心轴连接,电机用于驱使偏心轴转动以实现压缩空气。增压机采用四缸小行程布置,在不增加尺寸的前提下,还能有效降低排气噪音。
