Air filter and applicable air cleaning device

Abstract

The invention provides an air filter and an applicable air cleaning device. The air cleaning device comprises a negative charge generator. The air filter comprises an insulation shell, an insulation plate with an air duct, an inner insulation tube, a dust collection bin and an air suction fan. The insulation plate traverses the inner side wall of the insulation shell. One end of the inner insulation tube is fixed to one side of the insulation plate and arranged in the insulation shell in a suspended and sleeved mode. Two pole plates of a capacitor are arranged on the insulation shell and the inner insulation tube respectively. The capacitor is connected with the negative charge output end of the negative charge generator and used for exporting received negative charges to a negative charge gathering bin defined by the inner insulation tube, the insulation plate and the insulation shell. The dust collection bin is located on the other side of the insulation plate and used for collecting the negative charges flowing in through the air duct. The air suction fan is adjacent to the dust collection bin and used for leading air to flow in from the negative charge gathering bin and flow out through the air duct and the dust collection bin. By means of the air filter and the applicable air cleaning device, air cleaning efficiency is improved.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an air filter and an applicable air purification device. Background technique [0002] At present, air purification devices that use negative ions to collect dust usually include negative ion generators, electrostatic precipitators, suction fans, and the like. When working, the negative ion generator generates negative charges, and at the same time, the suction fan uses negative pressure to guide the air flow, so that the negative charges can absorb fine particles and float with the air flow to the electrostatic precipitator. The electrostatic precipitator uses the principle of static electricity to collect the negative charges adsorbed with fine particles. [0003] In the above-mentioned air purification device, the negative charges generated by the negative ion generator are directly released into the airflow, resulting in the dilution of the concentration of the negative charg...
