Abstract

The invention relates to the technical field of air pumps, in particular to an improved air pump magnetic rod fixing structure. The structure comprises a pump shell, a motor, a magnetic rod, a guide mechanism, a first air cylinder assembly and a second air cylinder assembly. The motor and the magnetic rod are arranged in the pump shell, and the two ends of the magnetic rod are connected with the first air cylinder assembly and the second air cylinder assembly which are arranged at the two ends of the pump shell respectively. The guide mechanism is fixed in the pump shell and connected with themagnetic rod, and the magnetic rod is driven by the motor to do reciprocating linear motion along the guide mechanism. According to the improved air pump magnetic rod fixing structure, the guide mechanism is arranged to be connected with the magnetic rod, so that when the motor drives the magnetic rod to work, the magnetic rod is limited to reciprocate at a certain position, the distance betweenthe magnetic rod and the motor can be fixed, a fixed gap between the magnetic rod and the motor is ensured when an air pump works, the relative position deviation of the magnetic rod and the motor isreduced to the greatest extent, so that the performance of the air pump is ensured.

Description

technical field

[0001] The invention relates to the technical field of air pumps, and more particularly, to an improved fixing structure for magnetic rods of air pumps. Background technique

[0002] The diaphragm air pump is a reciprocating pump that relies on the diaphragm to reciprocate in the cylinder to compress and deliver gas. The magnetic rod of the traditional diaphragm air pump is generally fixedly connected to the cylinder assembly through a leather cup, and the material of the leather cup is usually rubber, so the fixing method of the magnetic rod is a soft fixation. Therefore, during the working process of the air pump, the working position of the magnetic rod will be affected by the external force due to the softness and hardness of the cup, and the relative position between the magnetic rod and the motor will be deviated, thereby affecting the working efficiency and performance of the air pump.
