[0025] Embodiment 3

[0026] As Figures 2 - 5As shown in the figure, a UV disinfection device proposed by the present utility model. Compared with Embodiment 2, the detailed structure of the cleaning component is described in this embodiment. The cleaning component includes a storage bottle 8, a sponge block 9, a cleaning cloth 10, and a limiting component. Two storage bottles 8 are symmetrically arranged at the top of the housing 1. The storage bottle 8 is selected as a push-type alcohol bottle. One end of the storage bottle 8 away from the liquid outlet is used to connect with the limiting component. When the UV lamp tube 3 moves to both ends close to the storage bottle 8, the limiting component moves the storage bottle 8 away from the UV lamp tube 3, thereby controlling the discharge of alcohol in the storage bottle 8. The sponge block 9 is bonded to the liquid outlet of the storage bottle 8. An arc-shaped groove that fits the UV lamp tube 3 is provided on the sponge block 9. The cleaning cloth 10 is connected to the sponge block 9.

[0027] The limiting component includes a mounting plate 11, an elastic member 12, and a clamping block 13. The mounting plate 11 is detachably connected to the storage bottle 8. Both ends of the elastic member 12 for connecting between the mounting plate 11 and the inner wall of the housing 1. The elastic member 12 is selected as a conical spring. When compressed, the conical spring requires less space. A plurality of evenly distributed clamping blocks 13 are connected to the lower end surface of the cover plate 2 and the upper end surface of the moving plate 7. When the cover plate 2 and the moving plate 7 approach the storage bottle 8, the clamping block 13 pushes the storage bottle 8 to move.

[0028] In an alternative embodiment, a plurality of dovetail blocks 14 are connected to the storage bottle 8. The dovetail blocks 14 are slidably connected to dovetail grooves 15 provided on the mounting plate 11 of the housing 1.

[0029] In an alternative embodiment, a handle 16 is connected to the side wall of the housing 1. Anti-slip layers are connected to the handles 16. The setting of the handles 16 facilitates the user to pick up and move.

[0031] In summary, when the utility model is in use, the staff move the device to the location that needs to be disinfected, and then start the device. After the device is started, the output end of the driving device 4 rotates to drive the threaded rod 5 to rotate. The threaded rod 5 drives the moving plate 7 to move upward along the central axis of the threaded rod 5. The threaded rod 5 pushes the ultraviolet lamp tube 3 out between the shells 1 to disinfect the external environment. At the same time, when the ultraviolet lamp tube 3 moves, it will contact the storage bottle 8. When the storage bottle 8 is pushed by the elastic member 12, the sponge block 9 and the cleaning cloth 10 at its top contact the outer wall of the ultraviolet lamp tube 3. The storage bottle 8 is squeezed to a certain extent and alcohol is discharged from its liquid outlet. After the alcohol diffuses through the sponge block 9, it wets the cleaning cloth 10. The cleaning cloth 10 contacts the ultraviolet lamp tube 3 and wipes it. When the ultraviolet lamp tube 3 is completely exposed or retracted into the shell 1, the clamping blocks 13 on the moving plate 7 and the cover plate 2 contact the storage bottle 8. The clamping blocks 13 push the storage bottle 8 to move towards the inner wall of the shell 1, compressing the length of the elastic member 12, so that the liquid outlet of the storage bottle 8 stops being compressed, thereby stopping the pressing type alcohol bottle from discharging alcohol, reducing the waste of alcohol.

[0032] The above has described in detail the embodiments of the present utility model in conjunction with the drawings. However, the present utility model is not limited thereto. Various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the art to which it pertains.
