Light leakage prevention supporting structure of UV light source of air disinfecting machine

Abstract

The invention relates to the field of air purification, in particular to a light leakage prevention supporting structure of a UV light source of an air disinfecting machine. The UV light source comprises a lamp tube, a lampshade comprises a protective cover used for covering one end of the UV lamp tube and a light shield used for covering the other end of the UV lamp tube, an opening formed in thelight shield is opposite to an opening formed in the protective cover. Connecting rods are connected between the opening of the light shield and the opening of the protective cover in a bridging mode, annular light shielding pieces used for being arranged on the periphery of the UV lamp tube in an empty sleeving mode are fixed to the connecting rods and are perpendicular to the connecting rods. Amethod that a light shielding plate is arranged at an air inlet and an air outlet is replaced with a method that the lamp tube is covered with the lampshade, and besides, the outer part of the lampshade is in the shape of a bullet, so that wind resistance is reduced. The air treatment efficiency of the air disinfecting machine is improved.

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...

[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
