Title:
AIR PURIFIER
Document Type and Number:
WIPO Patent Application WO/2021/057226
Kind Code:
A1
Abstract:
The present utility model relates to the technical field of household appliances, and in particular to an air purifier. A filter assembly of the air purifier is mounted at an air duct inlet of an air duct, an air guide assembly is mounted at an air duct outlet of the air duct, and a supercharging structure is formed in the air duct between the filter assembly and the air guide assembly. The inner diameter of a supercharging air inlet of the supercharging structure is larger than that of a supercharging air outlet. Air entering the air purifier from the air duct inlet reaches the supercharging structure after being filtered by the filtering assembly. Due to the design of the inner diameter of the supercharging air inlet being larger than that of the supercharging air outlet in the supercharging structure, the flow speed of the air at the supercharging air outlet is increased, the circulation speed of the air is increased, the problems of a large amount of wind resistance in the air purifier and non-smooth air circulation are solved without increasing the power of a power device, extra noise and energy consumption generated when the air purifier is being used are prevented, and the working efficiency of the air purifier is improved.
