Description

Technical Field

[0001] The present invention relates to the technical field of glass cleaning, and particularly to a glass cleaning device for domestic service. Background Art

[0002] During the construction of high-rise buildings, in order to meet the lighting performance and aesthetics of high-rise buildings, outer-layer glass needs to be installed outside high-rise buildings. Due to long-term contact with the outside air, the glass is prone to adhering dust over time, affecting its aesthetics. Therefore, in order to ensure the aesthetics of the building, it needs to be cleaned, and at this time, it is necessary to invite domestic workers from a domestic service company for cleaning.

[0003] Glass cleaning is a cleaning method that uses cleaning agents to professionally clean glass. The method is to use a glass squeegee, a water wiper, and a high-efficiency glass cleaning agent to thoroughly remove dirt, and use a glass spatula to remove the dust and cement glue on the window frame and window seams. The cleaning agent contains antistatic components, and the glass after scrubbing is crystal clear and light-transmitting.

[0004] There are mainly two ways to clean the outer wall glass: the hanging board and the hanging basket method. The mainly used method is the simple and low-cost hanging board operation. During work, first select a fixed place to tie the rope on the roof platform, and determine whether the object for fixing the rope is firm. If it is not firm, a weight or a jib needs to be used for fixing. Pad the places where all ropes touch corners, edges, and eaves with rubber or carpet blocks to prevent friction damage; tie a special knot of the hanging rope in the U-shaped crab buckle on the sitting hanging board, and hang a bucket on the edge of the board, with less than half a bucket of cleaning agent (liquid medicine) inside. The operator brings a glass scrubber, a water wiper, a glass suction cup, a blade, and a rag, and then can get on the board to start work; the operator sits at the specified position on the hanging board, ties all the tools to the upper mouth of the hanging board and leans sideways; slowly lower the hanging board to reach the first working position; aim a water gun (or a spray bottle) at the working position to release water to initially remove the dust, then apply the cleaning agent on the glass surface, and then wipe it from left to right or from top with a glass squeegee, and finally dry the water on the edge with a rag; work and slide down at the same time until one operation is completed. After descending to the ground, remove the bucket, the hanging board, etc., and then move horizontally on the roof to start the second operation. This kind of hanging board operation for manually cleaning the outer wall glass is prone to missing some areas, and the cleaning effect and safety are poor. Summary of the Invention

[0033] During specific use, the main body 1 is adsorbed on the glass through the suction cups 8. The first driving part 4 operates to drive the driving wheel 5 to rotate. Under the tension of the driving wheel 5 and the driven wheel 6 on the synchronous belt 7, the synchronous belt 7 rotates, enabling the multiple suction cups 8 to cyclically adsorb on the glass, realizing walking on the glass. During the walking process, the cleaning mechanism at the front end of the main body 1 cleans stubborn stains such as bird droppings, and the wiping mechanism at the rear end of the main body 1 wipes and cleans the dust on the glass.

A plurality of liquid outlet holes 27 for wetting the cleaning roller 25 are arranged on the hollow rotating shaft 26. Both ends of the connecting pipe 28 are communicated with the liquid storage container 34 and the hollow rotating shaft 26.

[0039] Specifically, the liquid storage container 34 is used to store glass cleaning liquid.

The inner surface of the second driven pulley 23 is provided with a spline sleeve 32 adapted to the spline 31. The spline sleeve 32 is rotatably connected inside the main body 1 through a bearing seat.

[0041] Specifically, the second driving portion 11 drives the reciprocating lead screw 29 to rotate through the speed reducer. The reciprocating lead screw 29 drives the U-shaped frame 33 to reciprocate left and right in the forward direction through the lead screw nut 30. The U-shaped frame 33 drives the cleaning roller 25 to reciprocate left and right through the hollow rotating shaft 26, so that the cleaning roller 25 makes a reciprocating movement left and right during rotation, which is beneficial to improving the cleaning effect of the cleaning roller 25 on the glass.
