Intelligent air purifier

Abstract

The invention provides an intelligent air purifier and relates to air purifying devices. According to the intelligent air purifier, the problem that in the prior art, a filter element of an intelligent air purifier needs to be replaced frequently is solved. The intelligent air purifier comprises a ventilating pipe, a filter arranged in the ventilating pipe and a fan. An air inlet of the ventilating pipe is located outdoors, and an air outlet of the ventilating pipe is located indoors; the ventilating pipe communicates with a first manifold and a second manifold; a first control valve is arranged on the first manifold; a second control valve is arranged on the second manifold; a third control valve is arranged in the position, between an air inlet of the first manifold and an air inlet of the second manifold, on the ventilating pipe; a fourth control valve is arranged in the position, between an air outlet of the first manifold and an air outlet of the second manifold, on the ventilating pipe; and a pressure detection device for detecting the pressure difference of air on the two sides of the filter is arranged on the ventilating pipe. The manifolds and the control valves which are arranged on the ventilating pipe are utilized so that reverse-blowing cleaning of the purifier can be realized under the condition that the rotating direction of the fan is not changed.

Description

technical field [0001] The invention belongs to the technical field of intelligent air purifiers, and relates to an intelligent air purifier. Background technique [0002] At present, the commercially available air purification devices basically adopt the filter element dust removal mode, that is, dry adsorption dust removal. The disadvantage of this kind of air purification device is that if the filter element is not replaced in time, it will cause secondary pollution and cannot achieve the effect of air purification. At the same time, this kind of air purification device The air purification device needs to replace the filter element regularly, and the replacement of the filter element is not a small expense. Therefore, it is a technical problem to be solved at present to design a small household fresh air system with a low price and no need to replace the filter element. , In addition, for buildings, the air freshness of the air layers at different heights is different.

[0002] At present, the commercially available air purification devices basically adopt the filter element dust removal mode, that is, dry adsorption dust removal. The disadvantage of this kind of air purification device is that if the filter element is not replaced in time, it will cause secondary pollution and cannot achieve the effect of air purification. At the same time, this kind of air purification device The air purification device needs to replace the filter element regularly, and the replacement of the filter element is not a small expense. Therefore, designing a small household fresh air system with a low price and no need to replace the filter element, which uses a back-blowing self-cleaning filter element, is currently a technical problem that needs to be solved. , In addition, for buildings, the air freshness of the air layers at different heights is different. Usually, the air at the upper floors is better, but this is not necessarily the case. The air in the lower layer or somewhere in the middle is better, but the current air purification device cannot choose to absorb the air of different air layers according to the needs
