Waterproof structure of wet and dry dual-purpose dust collector motor

Abstract

The invention relates to the field of motor waterproof technologies, in particular to a waterproof structure of a wet and dry dual-purpose dust collector motor, and solves the problems that the heat dissipation effect becomes poor and the operation of a dust collector is affected after a motor mechanism is subjected to waterproof and antirust spraying. The edge of the waterproof disc is provided with a wind blocking wall tightly attached to the motor shell, the waterproof disc is provided with a plurality of connecting holes used for being in bolt connection with the motor shell, one side face of the waterproof disc is provided with an embedded groove, an oil seal is arranged in the embedded groove, and the oil seal is arranged outside the rotating shaft in a sleeving mode. The effect of improving the waterproof performance between the motor shell and the rotating shaft of the dust collector is achieved.

Description

technical field [0001] The present application relates to the field of motor waterproof technology, in particular to a waterproof structure of a wet and dry vacuum cleaner motor. Background technique [0002] The vacuum cleaner motor is the heart of the vacuum cleaner. The vacuum cleaner motor is mainly composed of the motor part and the fan part. Since the vacuum cleaner motor has high requirements on the speed, generally 80000-120000 rpm, it mainly uses a DC brushless motor to connect the fan to the motor. On the rotating shaft, a filter device is arranged outside the suction port of the fan. When the motor drives the fan to rotate, the fan sucks the dirt aligned with the suction port into the filter device and collects it. [0003] When the motor drives the rotating shaft to rotate at a high speed, wear is prone to occur between the rotating shaft and the motor housing, resulting in a gap between the rotating shaft and the motor housing. In order to reduce the moisture ca...

AI Technical Summary

Problems solved by technology

[0003] When the motor drives the rotating shaft to rotate at high speed, wear is prone to occur between the rotating shaft and the motor housing, resulting in a gap between the rotating shaft and the motor housing. In order to reduce the moisture generated by the airflow from the fan into the motor housing through the gap and further damage the motor mechanism Adverse effects caused by operation, the conventional method is to spray waterproof and anti-rust on the motor mechanism in the motor housing, and install a leak-proof sealing ring at the motor inlet, but the heat dissipation effect of the motor mechanism becomes worse after spraying, causing the motor to overheat and power off The frequency of self-protection increases, which affects the operation of the vacuum cleaner and needs further improvement
