electric fan air purifier

Abstract

The invention provides an electric fan air purifier which utilizes an electric fan as an air power part. According to the electric fan air purifier, blades of an existing electric fan are taken off, an axial flow impeller is installed, an O-shaped filter is installed in a front shroud of the electric fan blades in a close-fitting mode, an outer circle of the O-shaped filter is provided with an O-shaped ultra-fine composite filtering screen, and an inner circle of the O-shaped filter is provided with an O-shaped activated carbon filtering screen and an O-shaped front-arranged coarse filtering screen. A left metal piece end cover and a right metal piece end cover are connected and manufactured into the integrated O-shaped filter. Under the effect of the centrifugal force of the impeller, air is sucked into the filter through an air inlet round opening, passes through the filtering screens, and flows to the circumferential space of the impeller. The filtering screens in the O-shaped filter are made of high-standard filtering screen materials, and have the air purification effect same as that of air purifiers of various brands, the household electric fan is fully utilized, and the practical electric fan air purifier can be assembled only by buying the O-shaped filter and the axial flow impeller matched with the air purifier. The air purifier is low in cost, and easy to produce and popularize.

Description

technical field [0001] The invention relates to an air purifier, in particular to an electric fan air purifier. Background technique [0002] Due to the smog weather, the demand for air purifiers is increasing year by year. At present, various air purifiers widely sold in the market are mainly various brand products with filter mesh structure for indoor air circulation and filtration. Their structure is basically to purify Various filter screens are set inside the shell of the filter and form an airflow channel with the bellows and the fan. There are also control and operating components inside and outside the shell. The front cover is opened to form a filter room. The ultra-fine composite filter and activated carbon filter are important core components of air purification and need to be replaced regularly, but their cost is not high, and the shell part of the various filters is only used for air purification. Power components, but their cost is very high, more than 10 time...

[0002] Due to the smog weather, the demand for air purifiers is increasing year by year. At present, various air purifiers widely sold in the market are mainly various brand products with filter mesh structure for indoor air circulation and filtration. Their structure is basically to purify Various filter screens are set inside the shell of the filter and form an airflow channel with the bellows and the fan. There are also control and operating components inside and outside the shell. The front cover is opened to form a filter room. The ultra-fine composite filter and activated carbon filter are important core components of air purification and need to be replaced regularly, but their cost is not high, and the shell part of the various filters is only used for air purification. Power components, but their cost is very high, more than 10 times more expensive than core components, which is not conducive to the needs of ordinary people's families
