Packing sealing mechanism of motor in medium and small-scale electric appliance

Abstract

The invention discloses a packing sealing mechanism of a motor in a medium and small-scale electric appliance. The packing sealing mechanism comprises a shell, a motor in the shell and a motor base fixedly connected with the bottom of the motor; a lower cover for supporting the motor base is arranged in the shell, and a bottom sealing ring for flexible sealing is arranged in the lower cover and the motor base. The bottom sealing ring of the packing sealing mechanism disclosed by the invention can effectively reduce the noise, and is capable of packing the chamber located by the motor, therebyrealizing the sealing; the lip design improves the elasticity, and increases the noise reduction capacity; furthermore, the packing sealing mechanism is provided with a sealing part for realizing thesealing through the radial force, thereby realizing the effective fixing and sealing of a motor chamber, and the noise-absorbing and noise-reduction capacity is further increased; 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 sealing mechanism disclosed by the invention is suitable for the dry-wet dust collector, a water aspirator, a water pumper, a humidifier and various medium and small-scale electric appliances.

Description

technical field [0001] The invention relates to a setting and installation mechanism of a motor in an electrical appliance, in particular to a waterproof sealing mechanism for 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 other liq...
