Air purification device

Abstract

The invention provides an air purification device which is used for purifying air entering through an air inlet (1) and discharging the purified air through an air outlet (4). The air purification device comprises a charging unit (2) and a dust collection unit (3), wherein the charging unit (2) is used for processing air flowing in through the air inlet (1) and charging solid particles in the air; the dust collection unit (3) is used for processing the air flowing out through the charging unit (2) and collecting the charged solid particles in the air, thereby purifying the air; an electric field is formed in the dust collection unit (3); the electric field is used for enabling the charged solid particles to be applied with force in the direction opposite to airflow direction so that the charged solid particles are deposited in the dust collection unit (3). A dust collection plate of the air purification device is free of replacement and convenient to wash; meanwhile, the one-time purification efficiency is improved.

Description

technical field [0001] The invention relates to electrostatic dust removal technology, in particular to a household electrostatic air purification device. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for quality of life, so they pay more and more attention to air quality. For this reason, many families are equipped with household air purifiers. At present, the commonly used household air purifiers are mostly filter purifiers. This type of filter purifier uses a fan to draw air into the purifier, and then filters the air through a built-in filter. This filter-type air purifier generally uses a combination of HEPA filter, activated carbon filter, photocatalyst (cold catalyst, multi-far catalyst) and ultraviolet sterilization to treat the air, so as to filter dust, eliminate odors, and disinfect. . However, this kind of purifier has been used for a long time, and the filter screen will gather some dust. In...

AI Technical Summary

Problems solved by technology

However, this purifier has the following disadvantages: 1) due to the accumulation of dust, the dust collection plate will become more and more dirty, and the purification effect will decrease thereupon, and when it is cleaned, it is inconvenient to operate and there will be spots that cannot be wiped. blind spot

2) Due to the exposed electrodes, the distance between the electrode plates is limited. In order to prevent the air between the electrode plates from being electrically broken down, the distance between the plates is relatively large, which will greatly reduce the primary purification efficiency
