Background technique

At present, due to the aggravation of air pollution, the popularization of indoor decoration and the use of air conditioners, the indoor air pollution caused by it has attracted more and more people's attention. Indoor air purifiers are devices that are used to improve and improve indoor air quality. At present, the air purification devices used at home and abroad mainly include pure mechanical filter type, electrostatic type, chemical (or physical) adsorption type, negative ion type, ultraviolet sterilizing type, etc., purely mechanical filter type and electrostatic type purifiers can only It is used for dust removal and has been gradually phased out. Adsorption-type purifiers have the problem that the adsorption material is easily saturated. The negative-ion type is generally believed to only eliminate the physical effect of smoke and dust. It is powerless to remove bacteria, viruses and chemical pollutants. Harmful gases, odors and other organic matter, the above several purifiers can only eliminate specific part of the pollutants, which cannot meet people's needs. In addition, the above-mentioned various indoor air purifiers are relatively large in size and occupy indoor space.

Utility model content

The purpose of the utility model is to provide an indoor air purifier capable of purifying various pollutants, simple in structure and small in size.

In order to solve the above-mentioned technical problems, the indoor air purifier described in the utility model includes a cylindrical shell, the front and rear of the shell are respectively provided with an air outlet and an air inlet, and the air outlet is provided with There is a front cover, the air inlet is covered with a filter cover, and the housing is provided with a fan, a photocatalyst filter, an ultraviolet lamp and an electrostatic dust removal device, and the fan is arranged between the air inlet and the air outlet In between, the photocatalyst filter is arranged behind the filter cover, the ultraviolet lamp is arranged on the side of the photocatalyst filter, and the electrostatic precipitator includes a plurality of metal dust collecting plates and a plurality of metal wires, metal The dust collecting plates and the metal wires are respectively connected to the positive and negative poles of the high voltage power supply, and the metal wires are arranged between the metal dust collecting plates at intervals.

The photocatalyst filter screen is a honeycomb photocatalyst filter screen.

The metal dust collecting plate is a stainless steel plate, and the metal wire is a steel wire.

The casing is provided with a fan bracket, and the fan is arranged on the fan bracket.

The top of the housing is provided with a power switch, a knob for adjusting the power of the purifier, and an LED light.

Due to the adoption of the above structure, the utility model has the following beneficial effects: the flowing air first passes through the filter screen cover to remove the fine dust in the air, and when it flows through the honeycomb photocatalyst filter screen, the photocatalyst filter screen is activated by the ultraviolet lamp to produce a strong Free radical active substances with oxidizing ability can kill viruses and bacteria in a broad spectrum and can oxidize harmful pollutants in the air, decomposing them into non-toxic and tasteless substances such as carbon dioxide and water. Bacteria, viruses, and electrostatic precipitators absorb and remove various pollution residues, which can thoroughly purify the air. At the same time, the utility model has the advantages of simple structure, small size, and safe and reliable operation.
