A delivery pipe 42 is connected to the storage box 41 through a pump body, and the bottom of the delivery pipe 42 is connected to the spray plate 4, and a shaking component is arranged on the spray plate 4.

[0027] The driving assembly includes a movable groove 17, which is opened on a movable plate 16. A push rod 18 is movably inserted in the movable plate 16. A vertically arranged rotating plate 19 is fixedly provided at one end of the push rod 18 away from the movable groove 17. A rotating shaft 2 is fixedly provided at one end of the rotating plate 19 away from the push rod 18. The rotating shaft 2 is rotatably inserted on the horizontal plate 15.

[0028] By adopting the above technical solution, the movable plate 16 can drive the pressing wheel 24 below to repeatedly press back and forth on the dust removal cloth 13, so that the alcohol contacts the cloth more fully.

[0029] A vertically arranged screw rod 3 is threadedly inserted into the side wall of the first connecting plate 21 , and the bottom of the screw rod 3 is rotatably arranged on the second connecting plate 22 via a bearing. A limiting rod 31 is fixedly arranged on the top of the second connecting plate 22 , and the top of the limiting rod 31 is threadedly inserted into the first connecting plate 21 .

[0030] By adopting the above technical solution, the provided screw rod 3 can conveniently adjust the vertical height of the pressing wheel 24, so that the dust removal cloth 13 can better contact with the surface of the keyboard.

[0031] Two symmetrically arranged fixing frames 23 are fixedly provided at the bottom of the second connecting plate 22 , and a plurality of pressing wheels 24 equidistantly arranged are rotatably arranged inside the fixing frames 23 .

[0032] By adopting the above technical solution, such distribution is to better enable the pressing wheel 24 to press the surface of the home appliance to avoid dead corners on the surface.

[0033] The shaking assembly includes a shaking plate 43, both ends of which are movably inserted into the interior of the processing box 1, and both ends of the shaking plate 43 are fixed with L-shaped fixing rods 48, and one end of the fixing rod 48 away from the shaking plate 43 is fixedly connected to the spray plate 4, and a rectangular groove 44 is penetrated through the shaking plate 43, and an arc groove 45 is opened at the diagonal of the rectangular groove 44. A rotating rod 46 is rotatably provided at the middle end of the rectangular groove 44, and a Y-shaped push block 47 is fixed on the rotating rod 46. The end of the push block 47 can be abutted against the side wall of the rectangular groove 44, and the top of the rotating rod 46 is connected through the rotating shaft 2 through the first bevel gear.

[0034] By adopting the above technical solution, when the rotating rod 46 rotates, the shaking plate 43 can drive the spray plate 4 to move back and forth quickly and repeatedly. At this time, the alcohol sprayed through the nozzle under the spray plate 4 will change from a droplet state to a production line state, so that the alcohol can more quickly contaminate the entire cloth.

[0035] A horizontally arranged transmission rod 5 is rotatably provided on one side of the outer wall of the processing box 1, and the end of the transmission rod 5 is connected to the rotating shaft 2 through a first belt 51. A connecting shaft 53 is rotatably inserted into the end of the outer wall of the processing box 1 away from the first belt 51, and the end of the connecting shaft 53 is connected to the transmission rod 5 through a second bevel gear. A driving motor 56 is fixedly provided on the outer wall of the processing box 1 near the connecting shaft 53, and the output end of the driving motor 56 is coaxially fixed on the connecting shaft 53.

[0036] By adopting the above technical solution, the driving motor 56 can directly cause the rotating rod 46 and the rotating shaft 2 to rotate synchronously when working, thereby increasing the linkage of the device.

[0037] A small gear 54 is fixedly provided on the connecting shaft 53 , and a large gear 52 meshing with the small gear 54 is fixedly provided at the end of the driving roller 12 close to the connecting shaft 53 . The two driving rollers 12 are connected via a second belt 57 .

[0038] By adopting the above technical solution, the large gear 52 and the small gear 54 that are first set can make the driving roller 12 rotate together with the rotating rod 46 and the rotating shaft 2, but because the small gear 54 drives the large gear 52 to rotate, the driving roller 12 on the large gear 52 rotates slowly, and at the same time, in conjunction with the second belt 57, the two driving rollers 12 can rotate slowly, so that the dust cloth 13 on the driving roller 12 can be rolled up.

[0039] An electric rod 72 is fixedly installed inside the processing box 1 just above the mounting frame 7 , and an output end of the electric rod 72 is fixedly arranged on the mounting frame 7 .

[0040] By adopting the above technical solution, the electric rod 72 will push the mounting frame 7 and the cleaning roller 71 to move downward as a whole to contact the surface of the keyboard, so that some large particles of impurities on the surface can be directly cleaned.

[0041] A dryer 8 is fixedly mounted on one end of the processing box 1 away from the mounting frame 7 .

[0042] By adopting the above technical solution, the provided dryer 8 performs a drying operation on the surface of the keyboard after being treated with alcohol.

[0043] A plurality of symmetrically arranged limit frames 6 are fixedly provided on the surface of the conveyor belt 11 , and one end of the limit frame 6 connected to the conveyor belt 11 is flexibly connected.

[0044] Working principle: When in use, the staff puts the keyboard whose surface needs to be cleaned into two symmetrically set limit frames 6. At this time, the position of the keyboard set in the limit frame 6 is limited to avoid excessive displacement;

[0045] Then the conveyor belt 11 will drive the limited keyboard into the processing box 1. At this time, the keyboard will first be received by the cleaning roller 71 provided on the installation frame 7. The electric rod 72 will push the installation frame 7 and the cleaning roller 71 to move downward as a whole to contact the surface of the keyboard, so that some large particles of impurities on the surface can be directly cleaned. At this time, the conveyor belt 11 continues to transport the keyboard. During the movement of the keyboard, the alcohol in the storage box 41 will be sent to the spray plate 4 through the delivery pipe 42. At this time, the spray plate 4 sprays the alcohol onto the dust removal cloth 13 through the nozzle facing the side of the conveyor belt 11.

[0046] At this time, the driving motor 56 can work, and the driving motor 56 will directly drive the connecting shaft 53 to rotate. At this time, the rotating connecting shaft 53 will drive the rotating shaft 2 to rotate through the transmission rod 5 and the second belt 57. At this time, the rotating rotating shaft 2 drives the rotating rod 46 to rotate through the first bevel gear. When the rotating rod 46 rotates, it will directly drive the push block 47 to rotate. One end of the rotating push block 47 will abut against the inner wall of the rectangular groove 44. At this time, the push block 47 will push the shaking plate 43 to move. At this time, the shaking plate 43 will be pushed by the push block 47 to move toward one end. Move, as the end of the push block 47 rotates into the arc groove 45, the other end of the push block 47 will abut against the other side of the rectangular groove 44, and the push block 47 will push the shaking plate 43 to move to the original position. At this time, the shaking plate 43 will move back and forth quickly under the push of the rotating rod 46 and the push block 47. At this time, the shaking plate 43 drives the spray plate 4 to move back and forth quickly through the fixed rod 48. At this time, the alcohol sprayed from the nozzle below the spray plate 4 will change from a droplet state to a pipeline state, so that the alcohol can more quickly make the cloth fully stained;

[0047] After the above steps, the rotating shaft 2 will directly drive the rotating plate 19 to rotate. At this time, the push rod 18 fixedly arranged at the end of the rotating rotating plate 19 will push the movable plate 16 to move. As the rotating shaft 2 continues to rotate, the rotating plate 19 will drive the push rod 18 to continuously move from one end to the other end in the movable groove 17, and move repeatedly. At this time, the movable plate 16 will be driven to repeatedly translate in the cross plate 15. At this time, the second connecting plate 22 is driven to move repeatedly with the movable plate 16 through the first connecting plate 21 fixedly connected to the cross plate 15. Before this, the pressing wheel 24 at the bottom of the second connecting plate 22 can be adjusted by rotating the screw 3 to squeeze it. The dust cloth 13 stained with alcohol makes the dust cloth 13 fully contact with the surface of the keyboard with alcohol. At this time, the repeatedly moving second connecting plate 22 will directly drive the pressing wheel 24 in the bottom fixed frame 23 to move repeatedly. At this time, the driven pressing wheel 24 will make the dust cloth 13 stained with alcohol fully contact with the keyboard surface, so that the alcohol stained on the keyboard surface is more comprehensive. At the same time, alcohol has good dissolving ability and can dissolve organic substances such as grease, stains and dust. When alcohol contacts dust, the low surface tension of alcohol enables it to wet the entire surface, including small concave and convex positions. It will dissolve the organic components in the dust particles, making it easier to remove;

[0048] The keyboard after alcohol cleaning will be moved to the position below the dryer 8, and its surface will be dried, and then it will be conveyed to the downward processing area by the conveyor belt 11 for processing.

[0049] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
