[0018] Compared with the prior art, the invention has the following beneficial effects: the disinfection cabinet for multi-angle ultraviolet irradiation sterilization adopts a new structural design, and its specific contents are as follows: 1. Place the items to be disinfected on the loading turntable, turn on the first ultraviolet lamp to emit ultraviolet light to achieve the purpose of disinfection, turn on the drive motor during this process, and use the drive motor to drive the transmission screw to rotate. During the rotation of the transmission screw, the first slider is driven to move back and forth under the guidance of the limit slide bar, thereby changing the position of the first ultraviolet lamp to achieve the purpose of comprehensive disinfection of the items; Furthermore, during the rotation of the transmission screw, the extrusion cams coaxially fixedly installed at the left and right ends thereof are driven to rotate synchronously. During the rotation of the extrusion cam, the extrusion plate below it is squeezed, so that the extrusion plate drives the second slider to move downward, and then the second slider is reset under the elastic push of the reset spring, so that the second slider drives the second ultraviolet lamp to move up and down reciprocatingly. In this process, the friction between the friction roller and the inner wall of the cabinet is used to make the second ultraviolet lamp reciprocate, thereby expanding the irradiation range of the ultraviolet light; Furthermore, the reflective lens is used to reflect the ultraviolet light onto the surface of the object, so as to fully utilize the ultraviolet light. In addition, the connecting rope below the second slider drives the reflective lens to rotate up and down during the up and down movement of the second slider, so as to expand the reflection range of the reflective lens.

[0019] 2. During the UV disinfection process, turn on the heater inside the drying box to heat the air. The heated air is sprayed into the cabinet through the air outlet pipe, so that the hot air can be used to dry the surface of the object (the object generally needs to be cleaned before disinfection). At the same time, the dried hot air can improve the quality of the object and enhance the disinfection effect. Furthermore, the air ejected from the air outlet pipe drives the driving blades to rotate, and the driving blades drive the driving gear to rotate, so that the driving gear drives the driven gear meshing with it to rotate (since the gear ratio between the driven gear and the driving gear is 10:1, the power required to drive the blades does not need to be too large), and finally the driven gear drives the loading turntable to rotate slowly, so that the loading turntable drives the object to rotate to improve the disinfection effect.

[0024] When using the device, first place the items that need to be disinfected (such as medical equipment, etc.) on the loading turntable 4, then turn on the first ultraviolet lamp 5 and the second ultraviolet lamp 6 inside the cabinet 1, and use the ultraviolet rays emitted by the first ultraviolet lamp 5 and the second ultraviolet lamp 6 to irradiate and disinfect the items. During this process, turn on the drive motor 11, and use the drive motor 11 to drive the transmission screw 10 to rotate. During the rotation of the transmission screw 10, the first slider 8 is driven to move back and forth left and right under the guidance of the limit slide bar 9, and the movement of the first slider 8 is used to drive the first ultraviolet lamp 5 to move synchronously to expand its ultraviolet irradiation range.

[0025] Example 2: Please refer to Figure 3 , Figure 5-Figure 6 In order to increase the ultraviolet irradiation range, the present embodiment provides the following technical solutions, which specifically disclose that: the second ultraviolet lamp 6 is provided with an adjustment mechanism for changing its irradiation angle; the adjustment mechanism includes a second slider 12 installed at the left and right ends of the second ultraviolet lamp 6, and the second slider 12 is rotatably connected to the second ultraviolet lamp 6, and the second slider 12 and the second ultraviolet lamp 6 form an up and down sliding structure between the second slider 12 and the guide slide 14, and the guide slide 14 is fixedly installed on the inner walls of the left and right sides of the cabinet 1, and a reset spring 15 for pushing the second slider 12 to reset is fixedly installed inside the guide slide 14, and the second ultraviolet lamp 6 is provided with an adjustment mechanism for changing its irradiation angle; the adjustment mechanism includes a second slider 12 installed at the left and right ends of the second ultraviolet lamp 6, and the second slider 12 is rotatably connected to the second ultraviolet lamp 6, and the second slider 12 and the guide slide 14 form an up and down sliding structure, and the guide slide 14 is fixedly installed on the inner walls of the left and right sides of the cabinet 1, and the guide slide 14 is fixedly installed inside the guide slide 14.

[0026] During the rotation of the transmission screw 10, the extrusion cams 17 fixedly installed on the left and right sides thereof are driven to rotate synchronously. During the rotation of the extrusion cam 17, the extrusion plate 16 below it is squeezed. At this time, the extrusion plate 16 drives the second slider 12 fixedly installed therewith to move. The second slider 12 slides in the guide slideway 14. Afterwards, when it is out of extrusion, the second slider 12 is reset upward under the elastic pushing action of the reset spring 15. In this way, the second slider 12 is used to drive the second ultraviolet lamp 6 to move up and down reciprocatingly. During the movement of the second ultraviolet lamp 6, the friction roller 13 on its rotating shaft is in contact with the second ultraviolet lamp 6. Touch the inner wall of the cabinet 1, and use the friction force of the friction roller 13 to drive the second ultraviolet lamp 6 to rotate back and forth up and down, adjust the irradiation angle of the second ultraviolet lamp 6, and achieve the purpose of comprehensive irradiation of the object. During the rotation of the second ultraviolet lamp 6, pull the connecting rope 19 on its lower surface, and use the connecting rope 19 to pull the reflective lens 18 on the upper surface of the supporting plate 3, so that the reflective lens 18 rotates around the rotating axis. At this time, the reflective lens 18 is used to reflect the ultraviolet rays emitted by the first ultraviolet lamp 5 and the second ultraviolet lamp 6, so that the ultraviolet rays can better reach the surface of the object and achieve a better disinfection effect.

The driven gear 25 and the driving gear 26 are connected together, and the gear ratio between them is 10:1. A driving blade 27 is coaxially fixedly installed below the driving gear 26, and the driving blade 27 is located below the bearing plate 3, and the air outlet position of the driving blade 27 and the air outlet pipe 21 correspond to each other.

At the same time, the delivery pump 22 outside the air outlet pipe 21 is turned on, and the hot air in the drying box 20 is delivered to the inside of the cabinet 1 by the delivery pump 22, so as to achieve the purpose of heating, drying and disinfection. The hot air in the cabinet 1 enters the inside of the filter box 28, and the water-absorbing sponge 29 in the filter box 28 absorbs the moisture in the air. The dried air enters the drying box 20 again through the air inlet pipe 23; The airflow ejected from the air outlet pipe 21 blows the driving blade 27, thereby driving the driving blade 27 to rotate. At this time, the driving blade 27 drives the driving gear 26 fixedly installed on its upper end to rotate.
