air purification device

Abstract

One aspect of the present invention provides an air purification device, which is used to purify the air entering through the air inlet (1), and discharge the purified air through the air outlet (4), comprising: a charging unit (2) , which processes the air flowing in through the air inlet (1), for charging the solid particles in the air; and a dust collection unit (3), which treats the air flowing out through the charging unit (2) The air is processed to collect the charged solid particles in the air, so as to realize air purification, wherein an electric field is formed in the dust collection unit (3), and the electric field causes the charged solid particles to be affected by the airflow direction The opposite force causes the charged solid particles to deposit in the dust collection unit (3). The dust collecting plate of the air purifying device provided by the invention does not need to be replaced, is easy to clean, and improves the primary purification efficiency.

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
