Anti-leakage support structure of uv light source for air sterilizer

Abstract

The present invention relates to the field of air purification, in particular to an anti-leakage support structure for UV light sources of air sterilizers. The hood at the other end of the UV lamp tube, the hood and the protective cover have opposite openings, and a connecting rod is bridged between the opening of the shading cover and the opening of the protective cover, and the connecting rod is fixed with an empty sleeve on the outer periphery of the UV lamp tube. The ring-shaped shading sheet is perpendicular to the connecting rod. The method of setting the shading plate at the air inlet and outlet is replaced by the method of setting the lampshade outside the lamp tube. At the same time, the shape of the lampshade is set in an outer bullet shape, which reduces wind resistance and improves air disinfection. Air efficiency of the machine.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to an anti-leakage support structure for a UV light source of an air sterilizer. Background technique [0002] Ultraviolet light source is a common part of air disinfection machine. At present, the main ultraviolet light sources include UV lamp and UVLED. The shape of UV lamp is similar to that of ordinary fluorescent lamp. It is harmful to the human body, so during the use of the air sterilizer, it is necessary to ensure that the UV lamp irradiates more air, and at the same time, the light cannot be injected into the outside world through the air flow channel of the air sterilizer. Baffles are arranged at both ends of the flow channel or some multi-layer and complex light-shielding structures are used to prevent ultraviolet rays from leaking, such as the Chinese invention patent document "A UV Sterilization and Disinfection Lamp and Its Control Method" (Application Publi...

Problems solved by technology

[0002] Ultraviolet light source is a common part of air disinfection machine. At present, the main ultraviolet light source includes UV lamp and UVLED. The shape of UV lamp is similar to that of ordinary fluorescent lamp. It is harmful to the human body, so during the use of the air sterilizer, it is necessary to ensure that the UV lamp irradiates more air, and at the same time, the light cannot be injected into the outside world through the air flow channel of the air sterilizer. Baffles are arranged at both ends of the flow channel or some multi-layer and complex light-shielding structures are used to prevent ultraviolet rays from leaking, such as the Chinese invention patent document "A UV Sterilization and Disinfection Lamp and Its Control Method" (Application Publication No. CN 111228559 A ) provides an ultraviolet sterilizing and disinfection lamp, the air outlet and the air inlet are provided with a sunshield made of a material that blocks the ultraviolet rays emitted by the ultraviolet lamp tube from radiating to the outside through the lamp housing, and cooperates with the lamp housing and the spiral The shaped partition sterilizes the air in sections without leakage and outputs it to the outside world, but this design, especially the shading plates set at the air outlet and air inlet, will undoubtedly greatly increase the resistance in the process of air circulation and reduce the air pressure of the sterilizer. The processing efficiency increases the working noise of the sterilizer, therefore, it is necessary to improve the existing technology to solve the above technical problems
