Air micro-nano particles-filtering and purifying device

Abstract

The invention discloses an air micro-nano particles-filtering and purifying device. The device comprises an upper cover, a housing body, a filtration device arranged in the housing body, an air blower, a rotating air-outlet device and a base, wherein the housing body adopts a cylindrical form; the upper cover is arranged at the upper part of the housing body; an air inlet zone is arranged at the lower part of the housing body; the filtration device is arranged inside the housing body; a purification chamber is arranged inside the filtration device; the base is arranged at the bottom of the purification chamber; the air blower is arranged on the inner side of the purification chamber; a groove is formed in the lower surface of the base; a foldable handle is arranged inside the groove; the foldable handle is fixedly connected with the rotating air-outlet device arranged above the upper cover through a rotating shaft on the air blower. The device is simple and compact in structure and easy to operate and can effectively remove the pollutants in air; the device is low in power consumption and saves electric energy; with high purification efficiency, the device can realize air purification without using various catalysts, so as to significantly reduce production cost; the device is wide in application range.

Description

technical field [0001] The invention relates to an air purification device, in particular to an air filtration and purification device which is portable, small in size and aimed at polluting micro-nano particles in the air. Background technique [0002] my country's air pollution is becoming more and more serious, and the air quality in urban areas, especially large cities, is deteriorating, especially the content of PM2. Times or even several times, the indoor air quality of urban buildings in my country is deteriorating, which seriously endangers the lives and health of the people. For the sake of health, urban residents often wear masks when they travel. However, the filter mesh diameter of the masks we usually use is much larger than the size of PM2.5 polluting micro-nano particles in the air (PM2. Particles entering the lungs are the most harmful air pollutants to the human body). [0003] Now indoor air quality and indoor air pollution control and governance are getti...

Problems solved by technology

[0006] (3) In order to save energy, the airtightness of modern buildings has increased. Due to the imperfect ventilation facilities of the central air-conditioning system, indoor pollutants cannot be discharged outdoors in time, resulting in the deterioration of indoor air quality.

[0007] However, the air treatment and purification technologies currently on the market are basically unable to fully and effectively purify the pollutants in the air and fully meet the requirements of indoor air quality standards. It is urgent to develop methods that can comprehensively and effectively purify indoor air. Nanoparticle filtration and purification equipment came into being

Such as Chinese patent CN202590513U discloses a kind of air purifier, but its power consumption is large, not energy-saving, and purification efficiency is not high; Pollutants, but the use of a variety of catalysts, high manufacturing costs
