Fresh air purification system capable of adjusting filter level

Abstract

The invention relates to a fresh air purification system capable of adjusting the filter level. A purifying box (3) comprises a box body (31) and a filter device, wherein the filter device comprises afilter screen (32) and a standby filter screen (33) which are arranged in sequence in an air inlet direction, and the standby filter screen (33) is pushed by a hydraulic push device (34) which is connected with a connecting part (333); a monitoring unit (7) comprises a controller (6), a PM2.5 sensor (71) and an ozone sensor (72) which are arranged outside an air outlet (5) and are connected to the input end of the controller (6) as well as an air inlet fan (2), an alarm (8) and the hydraulic push device (34) which are connected to the output end of the controller (6). The fresh air purification system has the advantages of reasonable design, large dust holding capacity, large filter area and low filter noise, the filter effect of the filter device can be effectively increased, and additionally, the filter level can be increased according to the air quality of the air outlet, so that the filter effect is increased.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a fresh air purification system capable of adjusting the number of filtration stages. Background technique [0002] At present, in order to improve the effect of heating and cooling equipment, the promotion of high thermal insulation and high air tightness of living space is accompanied by the problem of indoor air pollution. The importance of fresh air purification has gradually entered people's field of vision. There are many types of fresh air purification systems on the market, but most of them only use the color of the light on the purifier to judge the air quality in the room, and cannot accurately display the quality of the existing air in the room. At the same time, the fixed filter in the purification system The number of stages cannot be adjusted according to the air condition, and the filter can only be replaced at a fixed time, which cannot guarantee the qual...
