The other end of the transfer connector is connected to one end of the screw, and the other end of the screw is connected to the piston and disposed inside the air pump housing.
[0007] Preferably, the air pump housing is provided with an air inlet and an air outlet. The motor body drives the screw to reciprocate, thereby driving external air to enter through the air inlet, compress it, and then exit through the air outlet.
[0008] Preferably, the transfer connector includes a connector body and a connecting rod, one end of the connecting rod is connected to the non-central part of the connector body, and the other end of the connecting rod is connected to the screw connection hole on the screw.
[0009] Preferably, a first rolling bearing is provided in the screw connecting hole, which enables the connecting rod to drive the screw to rotate more smoothly.
[0010] Preferably, the connector body and the connecting rod are integrally formed.
[0011] Preferably, it also includes a connecting screw, and the side of the connector body is provided with a body through hole, through which the connecting screw can pass to fix the transfer connector and the rotor.

An oil-impregnated bearing is provided in the limiting bracket through hole between the motor body and the cooling fan, and a second rolling bearing is provided in the limiting bracket through hole between the motor body and the air pump body.
[0013] The beneficial effects of the air pump motor of this utility model are as follows:
[0014] 1. By installing an oil-impregnated bearing in the through hole of the limiting bracket between the motor body and the cooling fan, and a second rolling bearing in the through hole of the limiting bracket between the motor body and the air pump body, the process of the motor driving the cooling fan and the screw can be made smoother.
