Abstract: Provided are a sterilization module and an air purifier, which are applied in the field of air sterilization. The sterilization module is applied in the air purifier. The sterilization module includes a frame, a plurality of wave-shaped plates, and at least one sterilizing lamp. The frame is provided with a channel running through the frame from one end to another end. The plurality of wave-shaped plates are arranged at intervals in the channel, where each of the plurality of wave-shaped plates is bent alternately from the one end to the another end of the frame, so as to form an air duct that is wave-shaped between two adjacent wave-shaped plates. The at least one sterilizing lamp is disposed on the wave-shaped plate and used to emit ultraviolet (UV) light towards the air duct.

Abstract: An ultraviolet sterilization lamp structure relates to the technical field of disinfection and sterilization, comprising: a lamp board; an ultraviolet lamp connected to the lamp board, a light source convex lens arranged on a positive side of the ultraviolet lamp, and a strip-shaped convex lens laterally arranged on an outer side of the light source convex lens. With the above technical solution, the ultraviolet light is optically zoomed twice through the light source convex lens and the strip-shaped convex lens to achieve an effect of vertical concentration and horizontal diffusion, ensuring that the horizontal angle of the irradiation is large and the vertical angle is small, avoiding the exposure to the personnel activity area, so that the personnel do not have to leave the room when sterilizing, thereby embodying the coexistence of man and machine and improving the immediacy and practicality of ultraviolet air sterilizing.

Abstract: A UVC-integrated LED structure adapted to air sterilization-and-disinfection grilles is provided. The UVC-integrated LED structure includes a housing, an opening disposed at top of the housing, multiple wavy grilles engaged with both sides of inner wall of the opening, placement grooves openly disposed at one side of the wavy grilles, and COB light boards disposed inside the placement grooves. The UVC-integrated LED structure installs the COB light boards at the placement grooves. The structure allows the COB light boards to be hidden on the surfaces of the wavy grilles for decreasing height of the COBs. Therefore, air resistance can be reduced when the ultraviolet ray irradiates on the passing air. The impact of dust being adhered to the COB light boards can be reduced. The air passing through the multiple wavy grilles can be sterilized and disinfected.

Abstract: A photocatalytic structure that can uniformize ultraviolet lights is provided. The photocatalytic structure includes a housing, a groove formed at a top of the housing, multiple grille slices being engaged with two sides of an inner wall of the groove, multiple grille passages being formed between every two adjacent grille slices, metal meshes disposed on both top and bottom of the grille slices, and a UVC-LED light board disposed at a side of the grille slices. The photocatalytic structure stacks the grille slices to form the grille passages. The UVC-LED light board makes grille passages to reflect the ultraviolet light. More uniform lights are formed at both upper and lower sides of the grille passages. The UVC-LED light board close to the metal meshes ensures the uniform lights to be emitted onto a gap plane with a smaller refraction angle. Therefore, everywhere on the metal meshes are fully illuminated.

Abstract: The present disclosure is related to an air sterilization-and-disinfection module that embodies two bactericidal factors. The module is directed to a field of sterilization for an air conditioning conduit. A corrugated board is disposed in the middle of the module. A plurality of wavy channels are formed in between multiple corrugated boards. Several metal meshes are disposed at top and bottom of the multiple corrugated boards. A sterilization component is disposed inside the wavy channels for sterilizing the air conditioning conduits. The two bactericidal factors are pure ultraviolet irradiation sterilization and photocatalyst sterilization. The sterilization component irradiates ultraviolet ray and the ultraviolet ray is spilled out from top and bottom of the wavy channels since the light is reflected by a reflective layer on the surfaces of wavy channels. The spilled ultraviolet ray stimulates the photocatalyst mesh on the metal meshes for achieving the two bactericidal factors.
