Practical air purifier

Abstract

The invention discloses a practical air purifier. The practical air purifier comprises an air purifier master machine, an air purifier submachine, a first air changing module, a first gas filter, a disinfection module, and a sterilization system, wherein the air purifier master machine comprises a housing; a prefilter, an electrostatic dust collection device, a photocatalyst filter dam, a negative-ion generator and a cross-flow fan are sequentially arranged in the housing; the photocatalyst filter dam is formed by metal grilles coated with a nano-sized titanium dioxide coating; a UV illuminating lamp is arranged at the top of the photocatalyst filter dam; the air purifier master machine comprises an air quality sensor and an intelligent controller; the air purifier submachine comprises a control module and an air purification device; the intelligent controller is used for transmitting control signals to start the air purifier master machine and the air purification device in the air purifier submachine to work; the sterilization system comprises an impurity removal filter screen, a smell removal filter screen, and a sterilizer. Through the adoption of the practical air purifier disclosed by the invention, toxic and harmful gas in the air can be effectively degraded, so that the air is fresh.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a practical air purifier. Background technique [0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc.), household appliances that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building. [0003] Due to the rapid development of industrialization and the increase of automobiles, China has become the country with the fastest increase in air pollution in the world. Air pollution has seriously affected people's healthy life, indoor and outdoor pollution parallel, facing internal and external troubles. Indoor air purification technology includes filtration method, negative ion method, ozone method, electrostatic meth...

AI Technical Summary

Problems solved by technology

Indoor air purification technologies include filtration method, negative ion method, ozone method, electrostatic method, activated carbon adsorption method, plasma method, etc. All the above-mentioned technologies have their own advantages and disadvantages, and the disadvantage of unity is that the disinfection and sterilization effect on air is poor.

In addition, more and more air purification devices use photocatalyst technology. Photocatalyst has the functions of sterilization, deodorization, air purification, hydrophilic antifouling and water absorption and ultraviolet rays, but the effect of removing and filtering large particle size pollutants is poor.

Due to the single function of the existing purifiers, different purifiers can only deal with different air pollutants, so it is far from meeting people's needs
