The invention provides an improved electric diaphragm vacuum pump. The improved electric diaphragm vacuum pump comprises a pump cover, a diaphragm assembly, a pump body and a motor, and a diaphragm on the diaphragm assembly is installed between the pump cover and the pump body; a circular driving disc is fixedly mounted on a motor shaft of the motor, and the two end surfaces of the driving disc are not perpendicular to the axis of the motor shaft; a driving shaft capable of doing axial linear reciprocating motion is arranged in the pump body, the driving shaft comprises a first vertical rod, a cross rod and a second vertical rod, the first vertical rod and the second vertical rod are connected through the cross rod and are parallel to each other, the other end of the second vertical rod is connected with the diaphragm, and an upper driving block and a lower driving block which protrude outwards are arranged on the first vertical rod; the peripheral part of a driving disc on a motor shaft stretches into the position between the two driving blocks of the first vertical rod, when the motor shaft rotates, the peripheral part of the driving disc can act on the two driving blocks to push the driving shaft to reciprocate up and down, then the diaphragm is driven to do reciprocating type air inlet and exhaust piston motion, and the air suction and exhaust process is achieved.
本发明提供了一种改进的电动隔膜真空泵,包括泵盖、膜片总成、泵体、电机,膜片总成上的膜片安装在泵盖和泵体之间;所述电机的电机轴上固定安装有一个圆形驱动盘,该驱动盘的两个端面与电机轴的轴线之间不相垂直;泵体内设有一个能够做轴向线性往复运动的驱动轴,该驱动轴包括第一竖杆、横杆、第二竖杆,第一竖杆和第二竖杆通过横杆相连且第一竖杆和第二竖杆互相平行,第二竖杆的另一端与膜片连接,第一竖杆上设有上下两个向外凸出的驱动块;电机轴上的驱动盘外周部分探入第一竖杆的两个驱动块之间,当电机轴旋转时,驱动盘外周部分会作用于两个驱动块上,推动驱动轴产生上下往复运动,进而带动膜片做往复式进排气活塞运动,实现抽排气过程。
