[0039] It is worth mentioning that the lampshade of the lamp body 2 is stored in the arc-shaped baffle 3 by rotating the storage mechanism 10, so that the lamp body 2 can be stored when not in use to reduce the adhesion of dust and stains; an I-shaped through hole is opened on the top surface of the water tank 11 to ensure the entry and exit of the cleaning cloth 4.

[0040] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that the rotating storage mechanism 10 includes:

[0041] The rack plate 101 is fixed to the other side of the frame 5. The outer surface of the lamp body 2 is fixedly sleeved with a first gear 102, which meshes with the rack plate 101 for transmission. The outer surface of the transmission roller 6 is fixedly sleeved with two symmetrically distributed second gears 103, one of which meshes with the rack plate 101 for transmission.

[0042] The driving motor 104 is fixedly mounted on the outer surface of the mounting box 1 , and the transmission roller 6 is coaxially connected to the output end of the driving motor 104 .

[0043] Further as Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, it is worth noting that the cloth cleaning mechanism 12 includes:

[0044] A mounting frame 1201, two mounting frames 1201 are provided and are respectively fixed on both sides of the inner wall of the water tank 11, the outer surfaces of the two mounting frames 1201 are rotatably connected to a cleaning roller 1202 matched with the cleaning cloth 4, one side of the two mounting frames 1201 is rotatably connected to a third gear 1203, and the third gear 1203 is coaxially connected to the cleaning roller 1202;

[0046] It is worth noting that: the two inner teeth 1211 in the rectangular ring 1210 are distributed diagonally; the surface of the cleaning cloth 4 is cleaned by the cleaning roller 1202 that rotates back and forth, so that the impurities attached to the surface of the cleaning cloth 4 are separated during cleaning, thereby cooperating with the water tank 11 to clean the cleaning cloth 4 and keep the cleaning cloth 4 clean, so that the cleaning cloth 4 can better clean the lampshade of the lamp body 2 next time.

[0047] Further as Figure 6 As shown, it is worth explaining in detail that two fixed rods 13 are symmetrically fixed to the inner wall of the installation box 1, and a support rod 14 is fixed on the side close to the two fixed rods 13. The support rod 14 movably passes through the moving rod 1209. The moving rod 1209 is limited by the support rod 14 to improve the stability of the moving rod 1209 when it moves horizontally.

[0048] Embodiment 2: Based on Embodiment 1, according to Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that a liquid tank 15 is fixedly installed on the upper end of the interior of the installation box 1. The top surface of the liquid tank 15 is arc-shaped and fits with the surface of the driving roller 6. A first liquid inlet pipe 20 is fixed to the top surface of the liquid tank 15. The first liquid inlet pipe 20 is convenient for timely adding of cleaning liquid in the liquid tank 15, and the operation of the user is convenient. When the driving roller 6 rotates, the surface of the driving roller 6 located in the liquid tank 15 will be stained with cleaning liquid. As the driving roller 6 rotates, the driving roller 6 stained with cleaning liquid soaks the cleaning cloth 4, and the soaked cleaning cloth 4 cleans the lampshade of the lamp body 2, thereby improving the cleaning effect.

[0049] Further as Figure 8 As shown, it is worth explaining in detail that movable grooves 16 are opened on both sides of the inner wall of the water tank 11, and the inner walls of the two movable grooves 16 are slidably connected with extrusion plates 17 that cooperate with the cleaning cloth 4. A plurality of springs 18 are fixed on the side where the two extrusion plates 17 are away from each other, and the ends of the springs 18 are fixed to the inner walls of the movable grooves 16. Under the elastic force of the plurality of springs 18, the two extrusion plates 17 are pushed closer to each other, and the water of the cleaning cloth 4 after washing is squeezed out, so that a certain humidity is maintained on the cleaning cloth 4 and the liquid does not drip, thereby reducing the splashing of liquid when the cleaning cloth 4 moves up and down.

[0050] Further as Figure 8 As shown, it is worth explaining in detail that two liquid guide plates 19 are fixed on the top surface of the water tank 11 corresponding to the cleaning cloth 4, and the two liquid guide plates 19 are both arranged at an angle to prevent the liquid on the cleaning cloth 4 from splashing.

[0051] Further as Figure 2 and Figure 3 As shown, it is worth specifically explaining that a second liquid inlet pipe 21 is fixed to the top surface of the water tank 11, and a liquid discharge pipe 22 is fixed to the lower end of one side of the water tank 11. After cleaning with the cleaning cloth 4 several times, the waste liquid in the water tank 11 is discharged by opening the liquid discharge pipe 22, and the water tank 11 is filled through the second liquid inlet pipe 21; valves are fixedly installed on the outer surfaces of the first liquid inlet pipe 20 and the liquid discharge pipe 22, and the liquid inlet and liquid discharge conditions of the first liquid inlet pipe 20 and the liquid discharge pipe 22 are respectively controlled by the valves; the back of the installation box 1 is connected to a back plate by bolts, wherein the surface of the back plate is provided with through holes for the first liquid inlet pipe 20, the second liquid inlet pipe 21 and the liquid discharge pipe 22 to extend out.

[0052] This scheme has the following working process: when the lamp body 2 is not in use, the driving motor 104 is started, so that the transmission roller 6 rotates, and then the transmission roller 6 drives the second gear 103 to rotate, thereby driving the rack plate 101 to move downward, and the rack plate 101 drives the limiting rod 7 to slide in the limiting slide groove 9 in the fixing seat 8 through the frame 5, so that the rack plate 101 drives the first gear 102 to rotate, thereby driving the lamp body 2 to rotate, so that the lamp body 2 rotates to the inner side of the arc baffle 3, so that the lamp body 2 is stored and protected when it is not in use, reducing the adhesion of impurities and stains on the lampshade surface of the lamp body 2, and preventing the lamp body 2 from being bumped during transportation and not in use;

[0053] The rack plate 101 continues to move downward, and the frame 5 drives the cleaning cloth 4 to move downward while the lamp body 2 rotates, so that the cleaning cloth 4 cleans the surface of the lampshade of the lamp body 2, thereby cleaning the dust and stains attached to the surface of the lampshade. When the transmission roller 6 rotates, the cleaning liquid in the liquid tank 15 will adhere to the transmission roller 6, so that the cleaning liquid on the transmission roller 6 soaks the cleaning cloth 4, thereby improving the cleaning effect of the cleaning cloth 4 on the lampshade. The cleaning cloth 4 moves down to the water tank 11. In the process of moving downward, the second gear 103 drives the third gear 1203 to rotate, so that the third gear 1203 drives the rotating rod 1207 to rotate through the fixed block 1206, and the moving rod 1209 is limited by the support rod 14, so that the rotating rod 1207 rotates and squeezes the movable ring 1208, thereby driving the movable ring 1 208 makes horizontal reciprocating movement, and then drives the rectangular ring 1210 to move horizontally through the moving rod 1209. The rectangular ring 1210 drives the inner teeth 1211 to move when moving horizontally reciprocatingly, thereby driving the fourth gear 1205 to rotate, and the rotating fourth gear 1205 drives the cleaning roller 1202 on the mounting frame 1201 to rotate back and forth, and the rotating cleaning roller 1202 squeezes the cleaning cloth 4, thereby cleaning the stains on the surface of the cleaning cloth 4 in the water tank 11 and keeping the cleaning cloth 4 clean. In the process of the cleaning cloth 4 moving up and resetting, the spring 18 pushes the two squeezing plates 17 to move closer to each other, squeezes the water from the cleaned cleaning cloth 4, so that a certain humidity is maintained on the cleaning cloth 4 and the liquid does not drip, thereby reducing the splashing of liquid when the cleaning cloth 4 moves up and down.

[0054] In summary: by rotating the storage mechanism 10 and the arrangement of the arc baffle 3, the lamp body 2 can be stored when not in use, and the lamp body 2 can be protected, the bumps of the lamp body 2 can be reduced, and the adhesion of dust and stains can be greatly reduced when the lamp body 2 is not in use, so as to keep the lamp body 2 clean. By rotating the storage mechanism 10 and the arrangement of the cleaning cloth 4, the dust and stains on the surface of the lampshade can be cleaned during the storage of the lamp body 2, which makes it convenient to clean the lampshade, thereby ensuring the brightness of the lamp body 2 when in use. The mutual cooperation of the structure 12 enables the cleaning roller 1202 to clean the stains on the surface of the cleaning cloth 4 and keep the cleaning cloth 4 clean, thereby realizing the functions of storing and cleaning the lamp body 2 and realizing the self-cleaning function of the cloth; through the mutual cooperation between the liquid tank 15 and the driving roller 6, when the driving roller 6 rotates, the surface of the driving roller 6 located in the liquid tank 15 will be stained with cleaning liquid, and as the driving roller 6 rotates, the driving roller 6 stained with the cleaning liquid soaks the cleaning cloth 4, and the soaked cleaning cloth 4 cleans the lampshade of the lamp body 2, thereby improving the cleaning effect.

[0055] The driving motor 104 can be purchased on the market. The driving motor 104 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
