Description

A floor-standing air purifier

technical field

The invention relates to the technical field of air purification, in particular to a floor-standing air cleaner.

Background technique

Now, with the acceleration of industrialization, air pollution is getting more and more serious. Many countries have formulated corresponding environmental governance laws and policies, and established various corresponding purification facilities. However, the control effect is not great, especially indoor pollution, which has seriously affected the physical and mental health of the human body. Among these indoor pollution, there are many pollutants, such as formaldehyde, benzene, toluene and TVOC, which are very harmful to the human body; fine particles are also quite harmful to the human body.

The development of air purifier equipment has gone through three stages: the first stage, mainly based on air filtration at first, this type of equipment is cheap, but the purification effect is very poor, easy to produce secondary pollution, and can only filter out large particles ; The second stage, this stage is mainly based on adsorption, using activated carbon materials, which can absorb pollutants in the air, but the adsorption capacity is easy to reach saturation, and cannot decompose harmful substances in it, such as formaldehyde , toluene and TVOC, etc.; the third stage is mainly based on decomposition, using catalysts or purification materials with decomposition functions to catalyze and decompose harmful substances in the air, so as to achieve the air purification effect. However, some conventional air purifiers on the market now have only one or two decomposition functions, which cannot fully purify and decompose harmful substances in the air, and various processing materials cannot be replaced and cannot be used for a long time, resulting in electronic waste and environmental damage. The secondary pollution is not in line with the social concept of energy conservation and environmental protection.

Chinese invention patent 2011101189708 discloses an indoor ceiling-mounted air purifier, which consists of a power supply, a mesh inlet, a roof with installation holes, an ultraviolet lamp, a photocatalyst filter, a HEPA filter, an activated carbon filter, a bracket, and a fan blade. , a protective cover, and a motor, which solves the problem of indoor high-concentration dirty air purification. After starting up and running, the dirty air is sucked in from the suction port with primary filter, first sterilized by ultraviolet light and photocatalyst filter, and then passed through the HEPA filter. Capture pollutants with a diameter greater than or equal to 0.03 microns in the air, with a filtration efficiency of 99.9%. Finally, the air passes through activated carbon to absorb odors and harmful gases, and the purified air is sent vertically downwards. This process produces a benign air circulation indoors with high efficiency. Purify the air to achieve the purpose of purifying the air. However, the patented technology has a limited effect on the purification of fine particles in the air
