Electric dust collecting filter of air purifier

Abstract

The electronic dust collector for air purifier features that it includes an ionizing part, which utilizes high voltage to charge dust in air passing through, and a trapping part, which is installed behind the ionizing part to utilize the electric field the ionizing part produces for adsorbing charged dust. The trapping part is made of positively charged foam with increased adsorbing area and consists of coiled metal plate and dust adsorbing soft film inside the coiled metal plate. The trapping part without power supply connected has long service life and high product quality.

Description

technical field [0001] The invention relates to an air purifier, in particular to an electronic dust collection filter. Background technique [0002] In general, air purifiers such as figure 1 with figure 2 As shown, it comprises the following parts, that is, a casing (1) with an air outlet (1') for exhausting air formed on the top and an open front; connected to the front open part of the casing (1), and There is an air intake grille (2) formed by an air inlet (2') that can allow air to flow in; a blower (7) that is installed inside the casing (1) and can force external air to circulate inside the casing (1) ); set on the back side of the air intake grille (2), an air filter (air filter) (3) that can filter out the larger dust in the inflowing air; set at the rear of the air filter (3) , the dust collection filter (4) that can use high voltage to ionize the dust in the inflowing air to capture it; the voltage generator (8) that can provide high voltage to the dust colle...

AI Technical Summary

Problems solved by technology

[0015] But, the problem that the existing electronic dust collection filter with above-mentioned structure exists is: because accelerating electrode and capture electrode are housed on the capture part, thereby need to be connected with power supply, and this will shorten the life-span of capture part, and will Decreases the work efficiency of the structure of the catch part

[0016] That is to say, since the acceleration electrode and the capture electrode inside the capture part need to be powered on, the electrode part will be damaged after a period of time, which is the main reason for shortening the life of the electrode part.

Of course, due to the need to install electronic products such as accelerating electrodes and capturing electrodes inside the capturing part, it will inevitably increase the defect rate and reduce the working efficiency.
