Dustproof and heat dissipation type portable motor

Abstract

The invention discloses a dustproof and heat dissipation type portable motor. The dustproof and heat dissipation type portable motor comprises a motor shell, wherein a heat dissipation assembly is mounted at the lower end of the motor shell; a fixing assembly is mounted at one side of the motor shell. The dustproof and heat dissipation type portable motor is scientific and reasonable in structureand safe and convenient to use; the heat dissipation assembly is arranged and gas is convenient to circularly flow in the motor under the action of an air inlet hole, a ventilation channel, an air outlet plate and a heat dissipation hole, so that the heat dissipation effect of the device is improved and the problems that the hole is formed in the outer side of the device to carry out heat dissipation so that rainwater enters the device from the hole are avoided; meanwhile, the ventilation channel is arranged so that the inner part of the motor is not in direct contact with the external environment and the damp-proof and dustproof effect of the device is increased; the fixing assembly is arranged, and a first fixed plate and a second fixed plate are convenient to combine under the action ofa fixed block, a fixed shaft, a first rotary shaft and a second rotary shaft; the motor is convenient to carry and transport by utilizing the effect of a carrying groove, and various functions of carrying and fixing are realized; the motor is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a dust-proof and heat-dissipating portable motor. Background technique [0002] The motor is represented by the letter M (the old standard is D) in the circuit.

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a dust-proof and heat-dissipating portable motor, which can effectively solve several major problems of the common motor in the above-mentioned background technology: 1. The connection mode between the rear shell of the motor and the shell of the motor is simple, and large gaps are likely to occur at the connection, making the device External dust is easy to be sucked into the motor from the gap during work, which has caused dust collection damage inside the motor for a long time. 2. When the motor is working, it is easy to generate a lot of heat due to the resistance of the coil. Ordinary motors dissipate heat by installing on the rear shell The heat dissipation effect is not obvious, and because the heat dissipation net is directly connected to the inside of the motor, rainwater and dust from the outside can easily enter the interior of the device, causing damage to the motor, etc. 3. Ordinary motor fixing devices and carrying devices It is installed separately, which increases the cost, etc. 4. Since the motor is prone to vibration during operation, the connection of the motor wires is easy to loosen, resulting in poor contact of the wires, etc. 5. During the transportation of the motor, due to the exposure of the motor device Outside, it is easy to collide with external objects and cause damage, etc.
