Air purification device

Abstract

The invention discloses an air purification device which comprises a housing, wherein an air inlet and an air outlet are formed in the housing; a filter element assembly, a germicidal lamp module and an air duct are sequentially arranged between the air inlet and the air outlet inside the housing; an air wheel is mounted in the air duct; the diameter of the air wheel is D; the air duct comprises a pipeline composed of a bottom plate, side walls and a cover plate; a circular diversion inlet corresponding to the air wheel is formed in the cover plate; the side walls are of a spiral involute structure; and a divergent flow channel composed of a straight line A and a straight line B is formed at the outlet of the air duct. According to the air purification device provided by the invention, air can be purified by a multiple purification module, the purification effect is excellent, and the effects of high filtering efficiency, large air outlet quantity, long conveying distance of clean air and low noise are achieved.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an air purification device. Background technique [0002] At present, air pollution is serious, and children's health problems are gradually being paid attention to. It is particularly important to create a healthy learning environment for children. In order to improve the air quality in classrooms, some air purifiers for classrooms have appeared on the market, which can purify classrooms to a certain extent. air, but these air purifiers have the following problems: 1. The purification effect is poor. The high-efficiency filter components of most purifiers are poor and thin, and the PM2. Larger particles fall on the high-efficiency filter element assembly. The high-efficiency filter element assembly has a high frequency of replacement, and if it is not replaced for a long time, the air volume is small and the purification effect is poor; 2. There is no photolysis tube, plasma, and...

[0002] At present, air pollution is serious, and children's health problems are gradually being paid attention to. It is particularly important to create a healthy learning environment for children. In order to improve the air quality of classrooms, some air purifiers for classrooms have appeared on the market, which can purify classrooms to a certain extent. air, but these air purifiers have the following problems: 1. The purification effect is poor. The high-efficiency filter elements of most purifiers are poor and thin, and the PM2. Larger particles fall on the high-efficiency filter element assembly. The high-efficiency filter element assembly has a high frequency of replacement, and if it is not replaced for a long time, the air volume is small and the purification effect is poor; 2. There is no photolysis tube, plasma, and negative ions. Most purifiers only filter through the filter element assembly Particles, no photolysis tube is installed or the installation of the photolysis tube is just a decoration, the air rarely flows through the photolysis tube, which leads to the bacteria, viruses, and odors in the air not being removed, and rarely installs plasma and negative ions; 3. The air volume is small or The noise is high, the air volume of the purifier is small, and the air cannot be purified quickly within a certain period of time. When the air volume is sufficient, the noise is too loud
