A motor bracket for fixing the vibration motor is provided inside the housing, and both ends of the motor bracket are suspended and installed inside the housing through a universal connector; the flapping plate is provided with a connecting column, and the housing is provided with a through hole corresponding to the connecting column, and the connecting column is connected and fixed to the motor bracket through the through hole; through the universal connector, the motor bracket equipped with the vibration motor is suspended and installed inside the housing, which can reduce the vibration transmitted to the housing by the vibration motor, and there will be no obvious numbness when holding the mite removal device. At the same time, the structural arrangement at both ends makes it mainly move up and down, meeting the working requirements of the flapping plate.

[0003] On the one hand, existing mite removal devices all have a dust collection function, and their air ducts are generally equipped with filters, such as the one disclosed in Chinese Patent No. ZL202222705434.4. However, when the mite removal device is in dust collection mode for a long time, dust and other debris easily adhere to the filter, causing the filter to become clogged. The mite removal device also has an air outlet on the top, and when the person holds the mite removal device, the top air outlet blows air towards the person.

[0004] On the other hand, the air inlet of the existing mite remover is in a normally open state, which causes garbage to easily fall out of the mite remover from the air inlet. Utility Model Content
