Window type air cleaning device

Abstract

The invention provides a window type air cleaning device comprising a main housing, a filter net, and a controller; two sides of the main housing are respectively provided with a first cover and a second cover; the first cover and a first side plate of the main housing form a first cavity; the second cover and a second side plate of the main housing form a second cavity; a driving roller and a first transition roller are arranged in the first cavity; a driven roller and a second transition roller are arranged in the second cavity; the filter net penetrates the first and second side plates, and comes around the driving roller, the second transition roller, the first transition roller and the driven roller in sequence; a first laser emitter, a first laser receiver, a second laser emitter and a second laser receiver used for detecting the filter net are arranged in a purifying channel. The filter net can be automatically replaced, purifying effect is good, and the work state of a purifier can be determined according to the real purifying effect.

Description

technical field [0001] The invention relates to the technical field of air purifiers, in particular to a window-type air purifier. Background technique [0002] Due to the frequent smog weather, people pay more and more attention to the use of air purifiers. Window purifiers mainly solve the problem of sucking air from the outside and discharging it into the room after purification, so as to ventilate and update the indoor fresh air. . [0003] Due to the existence of smog, the outdoor air quality is poor, and the air directly inhaled from the outside contains more dirt particles. Therefore, the filter at the inlet of the purifier often quickly accumulates a large amount of dirt, which greatly reduces the purification capacity. Sharp decline, the existing technology usually depends on the user to change the filter screen, which requires frequent replacement, which is very troublesome. Contents of the invention [0004] Based on the technical problems existing in the back...

[0003] Due to the existence of smog, the outdoor air quality is poor, and the air directly inhaled from the outside contains more dirt particles. Therefore, the filter at the inlet of the purifier often quickly accumulates a large amount of dirt, which greatly reduces the purification capacity. The sharp decline, the existing technology is usually changed by the user to replace the filter, which requires frequent replacement, which is very troublesome
