Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of dust collectors, and particularly relates to a sound-absorbing multi-purpose dust collector. BACKGROUND

[0002] Dust collectors can be divided into vertical, horizontal and wireless portable types according to structures. The working principle of a dust collector is that a motor drives a blade to rotate at a high speed to generate air negative pressure in a sealed shell to suck dust. The existing portable dust collector generates a large noise when in use, affecting user use. A dust collector capable of effectively reducing noise is disclosed in Chinese Utility Model Patent CN213189354U, but the dust collector has the problem of single function. A pet hair combing device using the principle of a dust collector is disclosed in Chinese Utility Model Patent CN216088278U. Specifically, when the dust collection function is used, the dust collection assembly is installed on the handle, and the air blowing part is turned to be opposite to the handle opening. At this time, the fan works, external air enters the handle through the dust collection nozzle, and negative pressure is generated at the dust collection nozzle to suck dirt such as dust and pet hair into the filter seat. However, the pet hair combing device has the problem that the motor generates a large noise or a large vibration during operation. In the process of combing pet hair, the noise and vibration cause the pet to have a fear psychology, and thus the pet resists the pet hair combing device, which brings great inconvenience to pet hair combing.
