Outdoor air purifier

Abstract

The invention belongs to the technical field of air purification, and discloses an outdoor air purifier. The outdoor air purifier comprises a case; a case door adopting the openable design is arranged at the front side of the case; air inlets are formed at both left and right sides of the case; rail-type clamping grooves are formed in the inner sides of the air inlets at both the left and right sides; filter screens are inserted in the clamping grooves; a filter cartridge is arranged at the upper part inside the case; a fan bin is formed at the lower part of the case; the top of the fan bin is open; the filter cartridge is mounted at the top of the fan bin; an opening of the filter cartridge is downward; an opening at the lower end of the filter cartridge is abutted with an opening at the top of the fan bin; an abutted face is sealed by a sealing cushion; two centrifugal fans with opposite rotating directions are symmetrically arranged side by side at the middles of the left and right parts in the fan bin; air inlets of the two centrifugal fans are on the contrary; air outlets of the two centrifugal fans pass downwards through the bottom of the fan bin to be communicated with an air outlet at the bottom of the case. The outdoor air purifier disclosed by the invention is reasonable in layout, compact in structure, small in integral size, large in effective filtering area, low in wind resistance and long in service life.

Description

technical field [0001] The invention belongs to the technical field of air purification, and relates to an outdoor air purifier. Background technique [0002] At present, domestic air pollution is serious, especially in smoggy weather. The air contains a large amount of particulate matter due to air pollution sources such as industrial waste gas, vehicle exhaust, and kitchen fume. The inhalation of these particles is very harmful to human health, especially the fine particles with a particle size of less than 2.5 microns seriously endanger human health. Under the current situation that air pollution has not been effectively prevented and controlled, it has become an urgent need for people to create a clean environment for the room through an air purification device. Closing doors and windows and using indoor purifiers can meet this demand, but maintaining a closed indoor environment for a long time is also detrimental to human health. [0003] Compared with the indoor puri...

AI Technical Summary

Problems solved by technology

[0004] The existing outdoor air purifiers used for fresh air systems mainly have the following deficiencies: 1. Larger volume

In the case of using multi-stage large-area filter elements, if the structural design is not compact enough, the overall volume of the purifier must be large

2. Under the limited volume, the purification efficiency is not high, and the service life of the filter element is short

3. Due to the outdoor installation of the purifier, the working environment is relatively poor, and the waterproof effect is an important functional indicator of the outdoor air purifier. The air inlet of the existing air purifier has poor waterproof effect, and water entering the interior of the purifier will easily cause the filter material to be damaged. damage

4. It is troublesome to replace the filter element
