Abstract

The invention relates to a motor cover, a motor assembly and a dust collector, and the motor cover comprises: a cover body which is provided with an accommodation cavity; an elastic sleeve, wherein atleast part of the elastic sleeve extends into the containing cavity and is connected with the inner wall of the containing cavity in a matched mode,a mounting hole is formed in the elastic sleeve inthe axial direction of the elastic sleeve in a penetrating mode, he elastic sleeve sleeves the motor through the mounting hole, a groove is formed in the inner wall of the mounting hole in a sunken mode and extends in the circumferential direction of the elastic sleeve, and the bottom wall of the groove supports a shaft shoulder of the motor. The elastic sleeve is sleeved outside the motor to provide certain buffer for the motor, protect the motor and absorb the vibration of the motor. Furthermore, a shaft shoulder of the motor is matched with a groove in the inner wall of the elastic sleeve;the groove extends in the circumferential direction of the elastic sleeve, the shaft shoulder can be supported in the whole circumferential direction of the motor through the bottom wall of the groove, the shaft shoulder of the motor can completely make contact with the bottom wall of the groove extending in the circumferential direction in the elastic sleeve in the circumferential direction, theelastic sleeve provides uniform buffering force for the motor from all positions in the circumferential direction, and the buffering performance of the elastic sleeve is improved.

Description

technical field [0001] The invention relates to the technical field of dust collection, in particular to a motor cover, a motor assembly and a vacuum cleaner. Background technique [0002] With the improvement of people's living standards, the requirements for the surrounding clean environment are getting higher and higher. Especially in household cleaning, it is necessary to thoroughly clean the dirt inside the house, but the traditional methods cannot meet the indoor cleanliness. And it takes time and effort, but the vacuum cleaner can effectively and quickly clean the stains and dirt in the room to meet people's requirements. Therefore, it is widely used by people. [0003] The vacuum cleaner includes a motor and a separator. The motor is used to drive the external airflow into the separator. The separator separates the dust in the airflow and discharges clean air. Among them, the motor provides aerodynamic force when it is working, and at the same time, it will generat...
