Embodiment 1

[0028] Such as figure 1 As shown, a filter device provided in this embodiment includes: a substrate; a filter screen 1, which is arranged on the substrate; and a microwave generating device arranged on the substrate or the filter screen 1, and the microwave generating device is suitable for heating the filter screen .

[0029] The filter device in this embodiment is a filter assembly in an air cleaner, where the base body can be a frame or an air duct of the air cleaner to facilitate the installation of the filter.

[0030] The microwave generating device in this embodiment is a common microwave generator, which generally includes two parts: a microwave tube and a microwave tube power supply. . The microwave tube is the core of the microwave generator, which converts DC electric energy into microwave energy.

[0031] In this embodiment, microwave heating has the following effects: microwave is a kind of electromagnetic wave, microwave frequency: 0.3-300 GHz; microwave wavel...

Embodiment 2

[0037] This embodiment provides an air purification device, including: an air duct; and a filtering device as described in Embodiment 1 disposed in the air duct.

[0038] In order to make microwaves effectively act on the filter, the microwave generating device in this embodiment is installed on the air duct wall of the air duct. As a variant, the microwave generating device can also be directly installed on the filter screen.

Abstract

The invention relates to the technical field of air purification, and particularly relates to a filtering device and an air purification device. The filtering device comprises a base body, a filter screen arranged on the base body, and a microwave generation device arranged on the base body or the filter screen, wherein the microwave generation device is suitable for heating the filter screen. Therefore, the temperature in a temperature field formed by heating an object through microwaves is more uniform, high-temperature disinfection dead corners are not prone to existing, and then the thoroughness of sterilization and disinfection is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a filter device and air purification equipment. Background technique [0002] Existing air purification equipment mostly adopts the method of setting a filter screen on the air flow channel to realize the filtration of particulate pollutants in the air. However, after the physical filter structure is used for a period of time, the dust accumulated on it is easy to breed bacteria, viruses, etc., causing secondary pollution to the purified air. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the filter screen in the prior art is likely to cause secondary air pollution, thereby providing a filter device and an air purification device. [0004] In order to solve the above problems, the present invention provides a filtering device, comprising: a substrate; a filter screen arranged on ...
