Air purifier

Abstract

The invention relates to the technical field of air purification and discloses an air purifier. The air purifier comprises a shell, a charge module, a dust filter, a coagulation module and a draught fan, wherein air inlets and air outlets are formed in the shell; the coagulation module, the dust filter and the charge module are sequentially fixed in the shell in the direction from the air inlets to the air outlets and communicate; the draught fan is used for enabling the air inside and outside the shell to circularly flow in the direction from the air inlets to the air outlets; the coagulationmodule is used for conducting coagulation and treating dust particles in the air flowing from the air inlets to the air outlets so that the interior space of the shell can form a coagulation cavity;and the charge module is used for charging non-coagulation dust and coagulated dust in the coagulation cavity so that the dust filter can capture the non-coagulation dust and the coagulated dust. Therunning noise and power dissipation of the air purifier can be reduced, meanwhile the filter efficiency of the dust filter is improved, and thus the overall purification effects and the usage experiences of the air purifier are improved.

Description

Technical field [0001] The present invention relates to the technical field of air purification, in particular to an air purifier. Background technique [0002] As urban smog pollution becomes more and more serious, air purifiers have gradually been widely used, especially in household life. In order to obtain ideal filtering performance, it is usually necessary to turn the air purifier to the maximum gear. However, although the air purifier has the best filtering performance when it is at the maximum gear, it will generate louder noise and affect sleep. For example, an air purifier with a nominal PCADR ≥ 400 cubic meters per hour, according to GB / T 18801-2015, the noise requirement of the air purifier is ≤ 66dB, but according to GB / 3096-1993 "Urban Area Environmental Noise "Standard" shows that people will have difficulty falling asleep in a noise environment of 66dB. [0003] At the same time, in order to improve the purification effect of the air purifier, it is generally achi...

Problems solved by technology

[0003] At the same time, in order to improve the purification effect of the air purifier, it is generally achieved by increasing the filter area of ​​the dust filter and replacing the high-efficiency filter material. High-quality filter materials will inevitably lead to a multiplied increase in the resistance of the dust filter. Therefore, most manufacturers will use high-pressure fans to meet the PCADR requirements of the air purifier. However, the use of high-pressure fans will further lead to air purifiers The power consumption and noise increase, so that most air purifiers have the problem of high noise and high power consumption at the same time
