Problems solved by technology

[0004] The air purifier uses an electrostatic precipitator, which is expensive, and this electrostatic dust collection is a process of charging the dust through high-voltage discharge, which is easy to generate ozone; in addition, the conventional negative ion generation method of the negative ion generator is a probe or a carbon brush. When the negative ions are released under the condition of high voltage, the concentration of negative ions released is usually low, and if a higher concentration of negative ions is required, the voltage needs to be increased, which puts forward higher requirements for product safety and cost. At the same time, the negative ions in the air In the field of purification, HEPA filters are often used to improve purification efficiency, but with the failure of HEPA filters, the purification efficiency gradually weakens

Abstract

The invention relates to a purification assembly and a filtering device applying the purification assembly, the purification assembly comprises a first filter screen made of a PET material, a second filter screen with electrostatic charges and a third filter screen capable of releasing negative ions, the first filter screen, the second filter screen and the third filter screen are stacked in sequence, and the third filter screen comprises a nano fiber structure prepared through electrostatic spinning. Anion powder is added into a spinning solution for spinning the third filter screen. Negative ion powder is added into the spinning solution for spinning the third filter screen, air around the negative ion powder is ionized, negative ions are formed, bacteria in the air are killed, people feel relaxed and happy, and the negative ions can be generated without high-voltage electricity; and moreover, the negative ions can be subjected to electret again on the second filter screen with electrostatic charges while being generated, so that the static electricity can be supplemented again after the static electricity of the second filter screen is lost, and the filtering efficiency of the particulate matters and the dust holding capacity of the particulate matters are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a purification component and a filtering device using the purification component. Background technique [0002] In recent years, with the rapid economic development, the problem of smog has become increasingly prominent and has become the focus of people's attention. The fine particles suspended in the smog can enter the lungs and cardiovascular of the human body through the respiratory system, leading to problems such as reduced immunity and lung cancer. Therefore, air purifiers are used more and more. [0003] Multi-layer filter screens are usually set in the air purifier, as shown in "A High-Efficiency Air Purifier" disclosed by the Chinese utility model patent No. CN201922381199.8 (notification No. CN211424576U). , air outlet, exhaust motor, primary filter plate, activated carbon adsorption plate, silver catalyst filter, electrostatic precipitator, HEPA ...
