High life diaphragm air pump

The utility model provides a high life diaphragm air pump, including casing, suspension arm set, suspension arm set includes permanent magnet and swing arm, the permanent magnet with the swing arm is connected, one side in the casing is equipped with the electro -magnet, and the opposite of electro -magnet is equipped with two flexible units, and two flexible units are arranged side by side, the head end of every flexible unit all with the swing arm is articulated, the other end of swing arm is equipped with magnetic conductive plate, magnetic conductive plate is close to the head end of electro -magnet is connected with the diaphragm between two swing arms, side in the casing is equipped with the cavity subassembly. Through change swing arm material, reduced the appeal between swing arm and the electro -magnet, reduced the atress and the friction of flexible original paper. Through increasing magnetic conductive plate, make air pump electromagnetism return circuit in the course of the work more stable to fin
