Air purifier

Abstract

The invention discloses an air purifier, which comprises a shell, a turbine fan, a filter screen, a water tank, a water filtration chamber, a shell air inlet and shell air outlets arranged on the shell. The water filtration chamber, the turbine fan and the filter screen are arranged in the cavity of the shell in order, the water tank is disposed below the water filtration chamber and the turbine fan, the water filtration chamber consists of a lower multifolded plate, an upper multifolded plate, a water filtration chamber outlet, and a water filtration chamber air inlet, the upper multifolded plate and the lower multifolded plate combine to form a multi-bending ventilation channel, the lower multifolded plate and water surface in the water tank combine to form a water filtration chamber air inlet, the water filtration chamber air inlet is communicated with the multi-bending ventilation channel, the turbine fan is disposed above the water filtration chamber and the filter screen, the air inlet of the turbine fan is communicated with the water filtration chamber outlet and the shell air inlet respectively, and the air outlet faces down and is communicated with the water filtration chamber air inlet. The air purifier provided by the invention has the advantages of simple structure and convenient installation, and the filter screen can be used for a long time and has no need for regular replacement.

Description

technical field [0001] The invention relates to the field of air filtration, in particular to an air purifier which does not need to replace the filter screen. Background technique [0002] With the improvement of people's living standards, more and more people begin to pay attention to the quality of the air, among which harmful factors such as formaldehyde and PM2.5 particles in the air are the objects that people focus on. Newly decorated houses or new furniture release harmful substances such as formaldehyde for a long time, which will cause great damage to people's health. [0003] PM2.5 particles have a small diameter, are not easy to settle naturally, are easy to deposit in the lungs, and contain a variety of toxic and harmful components. They can enter the lungs through the nostrils and throats of the human body, causing various diseases. The severity of PM2.5 harm to the human body is mainly related to the concentration of PM2.5 in the inhaled air and the inhalatio...

AI Technical Summary

Problems solved by technology

Multi-layer filtration and purification is currently the most widely used technology, usually consisting of preliminary filtration, HEAP high-efficiency filtration and activated carbon filtration. The air purification effect is better, and it can significantly reduce solid particles and formaldehyde in the air. The net needs to be replaced regularly, which is costly, time-consuming and laborious

[0005] At present, water filter air purifiers mainly use methods such as simulated rainfall and atomization to purify PM2.5 particles and formaldehyde. Although the air purification effect is good and there is no need to replace the filter element, the power consumption and noise of the purifier are relatively large, and the purified air high humidity
