Enclosed installation mechanism for motors in small and medium electrical appliances

Abstract

The invention discloses a packing mounting mechanism of a motor in a medium and small-scale electric appliance. The packing mounting mechanism comprises a shell, a motor and a motor base, the packingmounting structure is characterized in that at least one isolation cover is arranged in the shell, the motor is axially arranged in the isolation cover and the motor base, and a motor chamber for holding the motor is formed between the motor base and the isolation cover; an adapting clearance along a radial direction is formed at the sealing end of the motor chamber, and a radially adapted sealingpart is arranged in the adapting clearance. The effective fixation and sealing of the motor chamber are realized, the sealing part realizes the sealing through the radial force, and the sealing performance has nothing to do with the axial pressure of the motor, the situation of elasticity loss caused by large axial pressure is avoided, and the noise-absorbing and noise-reduction capacity is strong; the sealing part adopts the lip structure, can perform self-adaptive regulation according to the atmosphere, and cannot be located in the high-pressure state for a long time; the elastic attenuation of the sealing part is relieved, and the service life of the sealing part is increased. The packing mounting mechanism disclosed by the invention is suitable for the dry-wet dust collector, a wateraspirator, a water pumper, a humidifier and various medium and small-scale electric appliances.

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...
