Household air purifier and air purification method

Abstract

The invention belongs to the technical field of household appliances, and particularly relates to a household air purifier and an air purification method. The household air purifier comprises a controller, a shell, a fan and a filter plate; a cleaning mechanism is arranged in the shell; the cleaning mechanism comprises a front filter plate, an electric push rod, a brush, a liquid storage box, a liquid outlet and a hinge plate; the front filter plate is fixedly connected between the inner walls of the shell, and the electric push rod is embedded in the position, close to the front filter plate, of the inner bottom wall of the shell; the brush is fixedly connected to a piston rod of the electric push rod; the top of the shell is fixedly connected with the liquid storage box; and a liquid outlet communicated with the interior of the liquid storage box is formed in the top of the shell. The cleaning mechanism is arranged, so that the purification efficiency and the purification effect of the air purifier on the controller are improved, the service life of the front filter plate is prolonged, the use cost of the air purifier is saved, manual cleaning is not needed, disassembly and assembly of the air purifier are reduced, and the service life of the air purifier is prolonged.

Description

technical field [0001] The invention belongs to the technical field of household appliances, in particular to a household air purifier and an air purification method. Background technique [0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc.), products that effectively improve air cleanliness are mainly divided into household, commercial, industrial, and building. There are many different technologies and media in air purifiers, enabling it to provide users with clean and safe air Air. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collect...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the deficiencies of the prior art, the present invention proposes a household air purifier and an air purification method to solve the problems of daily cooking fume and poor air quality in the kitchen, and improve the air quality in the kitchen and near the kitchen through the air purifier. When the quality is high, a large amount of oil fume will adhere to the filter plate, which will affect the air permeability of the filter plate and reduce the purification efficiency and purification effect of the air purifier on the air.
