Description

technical field

[0001] The invention relates to the technical field of purification equipment, in particular to a discharge structure, a dust removal device and an air purifier. Background technique

[0002] With the improvement of national living standards and the pursuit of quality of life, air purifiers have gradually become people's daily necessities. Traditional air purifiers mostly use passive filters, which need to be replaced regularly, and there is a risk of secondary pollution when replacing the filters; after that, the electrostatic active purification device was born, which overcomes the need for regular replacement. However, it still has the problems of low discharge intensity, low purification efficiency, and easy to generate ozone during use. In addition, after a period of use, the electrostatic active purification device needs to be manually disassembled and cleaned by the user, which is inconvenient . Contents of the invention
