Description

Technical Field

[0001] The utility model relates to the technical field of air purification, and particularly relates to an ultraviolet air filtration and disinfection machine. Background Art

[0002] Indoor air often contains pollutants such as bacteria, viruses, dust, pollen, etc. These pollutants not only affect people's health but may also cause various respiratory diseases and allergic reactions. Therefore, how to effectively purify and disinfect indoor air has become an urgent technical problem to be solved.

[0003] Traditional air purification equipment usually relies on physical filtration, chemical adsorption and other means. Although these methods can remove pollutants in the air to a certain extent, the killing effect on bacteria and viruses is limited. Moreover, physical filtration and chemical adsorption materials are prone to saturation and need to be replaced frequently, increasing the use cost and maintenance difficulty.

[0004] In recent years, ultraviolet disinfection technology has gradually been applied to the field of air purification due to its advantages such as high efficiency and no chemical residue. Ultraviolet rays can damage the DNA or RNA structure of bacteria and viruses to achieve the purpose of killing microorganisms. However, a single ultraviolet disinfection device often has problems such as poor air flow and incomplete disinfection, making it difficult to ensure the comprehensive purification of air.

[0005] The Chinese utility model patent with the publication number of CN2626500Y discloses an ultraviolet air filtration and disinfection machine. It is recorded in the specification that "the machine shell ① installs the ultraviolet tube ⑤ inside the machine shell ①, thus avoiding the direct irradiation of ultraviolet rays outdoors. A number of glass tubes ② are connected around the ultraviolet tube. The main function of the glass tubes is to enable the air inhaled into the tube to slowly bypass along the ultraviolet tube, so that the air can be fully irradiated by ultraviolet rays to kill viruses. One end of the glass tube is fixed with an air inlet funnel ③ for air intake, and an air filter ④ is installed on the funnel. The main function of the air filter is to first filter out most of the air impurities, and the filter is directly irradiated by the ultraviolet lamp tube for a long time, so that most of the main viruses and bacteria are first killed. The other end of the glass tube outlet is connected to an exhaust funnel ⑧, and an exhaust fan ⑨ is installed in the funnel, and the gas is discharged from here."

[0006] It can be seen that the existing air purification equipment has the following main technical problems when dealing with air pollutants:

[0007] The coordination problem of multiple filtration and disinfection: How to effectively combine physical filtration and ultraviolet disinfection technologies to achieve the comprehensive purification and disinfection of various pollutants in the air.

[0008] Poor air flow: The internal structure of traditional equipment is complex, and the air flow path is unreasonable, resulting in poor air flow and reducing the purification efficiency.

[0009] Device Structural Compactness and Maintenance Difficulty: How to design a compact and reasonable structure to make the device easy to install and maintain, while ensuring the efficient operation of each component.

[0010] Through the above technical problems, we need a new device structure to solve these problems and ensure the efficient flow, filtration, and disinfection of air. Utility Model Content
