Air purifier

Abstract

The invention discloses an air purifier which comprises a casing, wherein the casing is provided with an air inlet and an air outlet; a first negative ion transmitter, a dust collector, an ion emitter group, a deionizer and a second negative ion transmitter are arranged from the air inlet to the air outlet in the casing; the second negative ion transmitter is arranged at the front end of the air outlet; and the deionizer is arranged at the front end of the second negative ion transmitter. The air purifier has the advantages of small wind resistance, low operation and maintenance cost and capabilities of simultaneously removing dust, carrying out broad-spectrum disinfection and removing odor and organic chemical gases; and in addition, O3 and nitrogen oxide can be omitted and negative ions can be released to improve the air quality, so that people feel more comfortable.

Description

[0001] 【Technical field】 [0002] The invention relates to an air purifier. 【Background technique】 [0003] The classic theory holds that bacteria and viruses spread by attaching to the dust, and the purpose of sterilization can be achieved by filtering the dust with a high-efficiency filter. At this time, the bacteria are blocked on the filter material and can reproduce. Commonly used filters can filter out dust larger than 0.1 μm. It is known that the particle size of viruses and other microorganisms is about 0.002-30 μm, and the particle size of bacteria is about 0.25-20 μm. At present, although there are low-resistance filter materials that can filter out more than 0.01 μm, some are loaded with disinfection enzymes such as cold catatase, photocatalyst, and lysozyme, and some use activated carbon filters to absorb organic chemical gases and remove odors. Flow purification technology and various air sterilizers, etc., and such products can also coexist with man and machin...

AI Technical Summary

Problems solved by technology

The disadvantages of the laminar flow purification system are: the overall project cost is high, the power consumption is large, bacteria can be filtered out but cannot be killed, and human discomfort is easily caused under high pressure, etc.

[0008] 3. Circulating wind ultraviolet sterilizer: it can sterilize but not remove dust, and the ultraviolet lamp will produce O 3 , the lamp tube is easy to age, and the efficiency will be reduced when the surface is covered with dust

[0009] It can be seen that most of these purification products are single dust removal or single sterilization type, the efficiency is not high, and some products cannot be used in the environment where man and machine coexist. Some products also have side effects, poor versatility, and can only meet the needs of specific occasions
