Efficient air purifier

Abstract

The invention provides an efficient air purifier, comprising a shell consisting of a front shell and a back shell, wherein the inside of the shell is hollow; the front shell is provided an air inlet, a fan is arranged on the back shell, and an air exhausting port of the fan is correspondingly an air outlet of the shell; a pre-filtering screen, an adsorption filter screen and a micro-particle filter screen are sequentially arranged in the shell along the direction from the air inlet to the air outlet and are arranged on a filter screen support frame, respectively; the filter screen support frame has a door type structure, and crisscrossed fixed links are arranged on the filter screen support frame; the adsorption filter screen is formed through alternate arrangement of a plurality of active carbon cylindrical particles, and the surfaces of the active carbon cylindrical particles are provided with micro-pores; and the micro-particle filter screen is composed of a stack of continuous front-back folded sub-glass fibrous membranes. The efficient air purifier has stronger adsorption filtration and stronger filtration energy efficiency.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a high-efficiency air purifier. Background technique [0002] The hazards of indoor air pollution have been recognized by people, and people have gradually begun to take measures to purify their own indoor air; there are many types of indoor air purifiers, but their efficiency is low. Generally, in order to achieve better filtering effects, 7 to 10 layers of filter screens are often installed, too many filter screens will lead to low filtration efficiency, and frequent replacement of filter screens is required; the structure of the existing air purifier with multi-layer filter screen structure is too complicated and the cost is high. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a high-efficiency air purifier, which has a simple structure, can ach...
