Double-cavity air purifier

Abstract

The invention relates to a double-cavity air purifier. The double-cavity air purifier comprises a shell, an air purification device and an air humidification device; the shell comprises a first innercavity, a second inner cavity, an air inlet and an air outlet; the first inner cavity is internally provided with a first filter net, and the air purification device is arranged in the first filter net; the air purification device comprises an air pump, a first water trough and an ultraviolet lamp, the first water trough is internally provided with a water solution and photocatalyst active balls,and the top of the first water trough is connected and communicates with the air outlet through an exhaust funnel; and the air humidification device is arranged in the second inner cavity and comprises a second water trough, a heater, a first water pump, a second water pump, a water distributor and an evaporator. According to the double-cavity air purifier, soluble organic pollutants in air are dissolved and adsorbed through the water solution, then, photocatalytic degradation is conducted on dissolved matter through the photocatalyst active balls in the water solution so that the efficiency of the air purifier can be improved, and the humidification function of the air purifier is additionally achieved through the double-cavity design.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to a double-chamber 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] There are a variety of different technologies and media in the air purifier, enabling it to provide users with clean and safe air. Among them, the commonly used air purification technologies are: filter element filtration technology, activated carbon adsorption technology, activated carbon loaded photocatalyst degradation technology and water dissolution Filtration technology, etc. However, these techni...

AI Technical Summary

Problems solved by technology

However, these technical methods all have the problem of low efficiency. For example, the filter element filtration technology can only reduce the pollution of solids such as PM2.5, but it cannot work on gases such as formaldehyde and benzene series; The efficiency of degradation technology is low; although the efficiency of water-dissolving filtration technology is high, the aqueous solution in water-dissolving filtration technology is easily saturated, so it needs to be replaced continuously
