Starter anti-water-immersion structure

Abstract

The invention discloses a starter anti-water-immersion structure, wherein the body cavity of the starter is a closed space; at least two breathing pressure valves are arranged on the body, are one-waynon-return structures, and are arranged on the body in opposite flow directions to form a natural suction port and an exhaust port. The starter uses a structure in which the body is sealed and two groups of breathing pressure valves are used together, and fully ensures the waterproof performance. The breathing pressure valves achieve air pressure balance in the body cavity, can automatically exhaust the air in case of internal high-pressure expansion, and causes oxygen lack to automatically extinguish the fire in case of internal combustion, thereby achieving waterproof, fireproof, and internal pressure adjusting functions, improving the performance of the starter in an extreme state, and achieving a functional breakthrough of the motor.

Description

technical field [0001] The invention relates to the technical field of motor sealing, in particular to a water-immersion-proof structure of a starter. Background technique [0002] The motor is a kind of equipment with high functional requirements. It is vulnerable to external dust and water, which affects its service life. Especially under harsh environmental conditions, the sealing requirements are higher. Especially the waterproof requirement, so the ideal structure of the inner cavity of the motor should be a closed structure. However, the motor will generate heat when it is continuously working, and the internal gas will expand when the inner cavity is sealed, and the increase in internal pressure will cause the body to rupture. , and even under extreme conditions, high temperature and heat will cause the motor to burn out. Therefore, there are disadvantages in the completely sealed structure. In addition to the water resistance of the body, the expansion exhaust capac...
