Air purifier

Abstract

The invention discloses an air purifier. The air purifier comprises a purifier casing, an air inlet fan, a filter net, a water mist generator, an electrostatic device and a sewage storage box, wherein the air inlet fan is mounted on the inner side of an air inlet or an air outlet of the purifier casing; the filter net comprises a front filter net body and a back filter net body which are mounted on inner sides of the air outlet and the air inlet of the purifier casing respectively, and the front filter net body, the back filter net body and the purifier casing form an airtight cavity; the water mist generator is mounted at the bottom of the airtight cavity, is used for generating small water mist particles with high concentration and enables the cavity to be full of the particles; the electrostatic device is mounted in the purifier and matched with the water mist generator to enable the water mist particles to be charged; the sewage storage box is mounted at the bottom of the purifier. The air purifier has the benefits as follows: the filtering effect is good; charged water mist is collected into the sewage storage box after adsorbing dust, and the air purifier is easy to clean and convenient to use; no consumable is used, core filter components are not required to be replaced frequently, and the using cost is reduced.

Description

technical field [0001] The invention relates to an air purifier, in particular to an air purifier used for indoor air purification and dust removal of residents. Background technique [0002] Environmental pollution is becoming more and more serious, and tiny dust in the air seriously affects people's health. It is generally believed that particles with a size smaller than 2.5 μm (PM2.5) can enter the human respiratory system and cause harm to the human body. Due to the very small size of PM2.5, ordinary doors and windows cannot effectively block PM2.5 particles from outside, so it is very necessary to place air purification equipment indoors. General air purification equipment adopts passive filtering technology, that is, single-layer or multi-layer filter screens are used to filter the air blown in by fans. Air purifiers using this technology require that the filter mesh is fine enough to filter dust with a particle size of less than 2.5 μm. However, there are many disa...

AI Technical Summary

Problems solved by technology

However, there are many disadvantages in the use of filter mesh, such as: the mesh size of the filter mesh is too dense, it is very easy to block, and needs to be replaced frequently; the manufacturing process of the filter mesh is complicated, and the cost of use is high
