Sealing installation mechanism of motor in small and medium-sized electrical appliance

Abstract

The invention discloses a sealing installation mechanism of a motor in a small and medium-sized electrical appliance. The sealing installation mechanism comprises a shell, a motor in the shell and a motor seat which supports the motor. The shell is internally provided with at least one isolation cover. The motor is axially arranged between the shell and the motor seat. A motor chamber accommodating the motor is formed among the shell, the motor seat and the isolation cover. An axial mating gap along an axial direction is between the isolation cover and the motor seat. The axial mating gap hasan axially-mated first seal member which has an elastic support part. A section of the elastic support part is a door-shaped structure. The elastic support part has an opening facing the axis direction of the motor. The sealing installation mechanism provided by the invention has strong noise absorption and noise reduction ability.

Description

technical field [0001] The invention relates to a setting and installing mechanism of a motor in electrical appliances, in particular to a waterproof sealing and installing mechanism of a motor in a small and medium-sized electrical appliance, and belongs to the technical field of H02K in the International Patent Classification Table. Background technique [0002] The motor, commonly known as the motor, refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. [0003] The setting and installation of the motor in the electrical appliance needs to consider two aspects: one is the fixing of the motor, which needs to prevent the series excitation motor from starting and rotating, so that the motor can be fixed during normal operation; the other is sealing to prevent water and...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the sealing structure of motors in small and medium-sized electrical appliances such as wet and dry vacuum cleaners in the prior art is relatively simple, and they are all simply sealed by axial pressure seals. The water-proof performance is poor, and the sealing effect depends entirely on The axial pressure, the sealing performance is inversely proportional to the noise absorption ability of the seal under pressure, that is, the better the sealing performance, the worse the noise reduction ability
