DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, an embodiment of the utility model provides an air purifier ultraviolet sterilization device, which is composed of a main body mechanism 10 and a mounting mechanism 20.

[0027] The main body mechanism 10 includes a mounting shell 11, an arc-shaped ultraviolet lamp tube 12 and a connecting seat 17. Three connecting seats 17 are equidistantly distributed and fixedly connected to the interior of the mounting shell 11. Three arc-shaped ultraviolet lamp tubes 12 are equidistantly distributed on one side of the interior of the mounting shell 11, and one end of the arc-shaped ultraviolet lamp tube 12 is connected to the connecting seat 17. The connecting seat 17 is powered and the arc-shaped ultraviolet lamp tube 12 is powered by the connecting seat 17. A slide groove 16 is integrally formed on one side of the mounting shell 11. Three sliders 33 are slidably connected to the interior of the slide groove 16. A fixing frame 14 is fixedly connected to one side of the slider 33. The fixing frame 14 is used to limit the arc-shaped ultraviolet lamp tube 12 to prevent the arc-shaped ultraviolet lamp tube 12 from falling. A fixing bolt 15 is threadedly connected to one side of the fixing frame 14. One end of the fixing bolt 15 is threadedly connected to the mounting shell 11, so that the fixing frame 14 can be disassembled by the fixing bolt 15, and the arc-shaped ultraviolet lamp tube 12 can be disassembled and assembled.

[0028] In one embodiment, in order to prevent the ultraviolet rays from leaking out and to limit the ultraviolet irradiation range, a reflective film 18 is fixedly connected to the interior of the mounting shell 11 .

[0029] In one embodiment, in order to facilitate cleaning of the surface of the arc-shaped ultraviolet lamp tube 12, three sliding racks 13 are equidistantly arranged on one side of the mounting shell 11, and a protrusion 32 is integrally formed on one side of the sliding rack 13. The sliding rack 13 is slidably connected to the slide groove 16 through the protrusion 32. A soft brush 19 is fixedly connected to one side of the sliding rack 13. The soft brush 19 is driven to move by moving the sliding rack 13, so that the soft brush 19 cleans the dirt on the surface when passing through the arc-shaped ultraviolet lamp tube 12, thereby preventing the dirt on the surface of the arc-shaped ultraviolet lamp tube 12 from affecting the sterilization effect. A magnetic block 31 is symmetrically fixedly connected to one side of the sliding rack 13, and the magnetic block 31 adsorbs the connecting seat 17, thereby fixing the position of the sliding rack 13, thereby preventing the sliding rack 13 from sliding arbitrarily and blocking the arc-shaped ultraviolet lamp tube 12.

[0030] The mounting mechanism 20 includes a fixing plate 21, a screw 23 and a pressing plate 22. The fixing plate 21 and the pressing plate 22 are evenly distributed and fixedly connected to one side of the mounting shell 11. The screw 23 penetrates the fixing plate 21. The screw 23 penetrates one side of the fixing plate 21 and is threadedly connected to the fixing plate 21. One end of the screw 23 is rotatably connected to the pressing plate 22. A rubber pad 26 is fixedly connected to one side of the pressing plate 22. The screw 23 drives the pressing plate 22 and the rubber pad 26 to move, so that the rubber pad 26 fits with the inner wall of the air purifier, thereby fixing the mounting shell 11. A sliding rod 24 is symmetrically fixedly connected to one side of the pressing plate 22. One end of the sliding rod 24 penetrates the fixing plate 21. The sliding rod 24 penetrates one end of the fixing plate 21 and is fixedly connected to a limiting block 25. The sliding rod 24 enhances the stability of the pressing plate 22 during movement.

[0031] When the utility model is in operation: different numbers of arc-shaped ultraviolet lamp tubes 12 are selected according to the sterilization requirements of the air purifier, and the arc-shaped ultraviolet lamp tubes 12 are installed in the installation shell 11 according to the sterilization position, so that the arc-shaped ultraviolet lamp tubes 12 are connected to the connecting seat 17, and the fixing frame 14 is sleeved on one side of the arc-shaped ultraviolet lamp tube 12, so that the slider 33 is stuck in the slide groove 16, and the position of the fixing frame 14 is fixed by the fixing bolt 15, and the arc-shaped ultraviolet lamp tube 12 is limited by the fixing frame 14, and the sliding frame 13 is moved, so that the sliding frame 13 drives the soft brush 19 to pass through the surface of the arc-shaped ultraviolet lamp tube 12 to clean the surface of the arc-shaped ultraviolet lamp tube 12, and the installation shell 11 is placed in the air purifier, and the screw 23 is rotated to drive the pressing plate 22 and the rubber pad 26 to move toward the inner wall of the air purifier, so that the rubber pad 26 contacts the inner wall of the air purifier, and the pressing plate 22 squeezes the rubber pad 26, so that the rubber pad 26 fits the inner wall of the air purifier, so that the installation shell 11 is quickly installed in the air purifier.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
