[0002] A window cleaning machine is a device used for cleaning and repairing windows and exterior glass of buildings or structures. It helps workers complete the cleaning of exterior windows of high-rise buildings. It moves by alternating adsorption of two suction cups and automatically cleans through a cleaning disc.

[0003] Publication number CN209733819U provides a new window cleaning robot, which includes a machine body and a bottom cover. The machine body is installed and fixed on the upper end of the bottom cover, and an elastic retractable rope is provided in the middle of the front end of the machine body.

[0004] The above-mentioned window cleaning robot has a good effect of reasonably changing the safety length according to the position of the window cleaning robot. However, during the movement, since the two suction cups and the cleaning plate are alternately adsorbed for movement and cleaning, the cleaning plate is separated from the glass during cleaning, reducing the cleaning force of the glass, and external air can easily enter through the cleaning plate during adsorption, reducing the stability of the suction cup and making it inconvenient to move.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] Combine Figures 1-4 A mobile structure of a circular window cleaning machine includes a chassis 1, an adsorption component 2 is installed on the front of the chassis 1, and a sealing component 3 is installed on the outside of the adsorption component 2.

[0025] See Figure 2 , it is further obtained that the adsorption component 2 includes two rotating shafts 4 and two transmission teeth 5. The two rotating shafts 4 are installed at the front of the chassis 1. The outer rear ends of the two rotating shafts 4 are fixedly sleeved with transmission teeth 5. Transmission blocks 6 are movably installed inside the two rotating shafts 4. A limit plate 7 is fixedly installed at the rear of the transmission block 6. A first spring 8 is installed at the rear of the limit plate 7 and located inside the rotating shaft 4. A guide tube 9 is movably connected to the interior of the transmission block 6. A cleaning disc 10 is fixedly installed at the front of the two transmission blocks 6. A suction groove 11 is opened in the center of the front of the cleaning disc 10. A suction cup 12 is installed at the front end of the guide tube 9 and located in the suction groove 11.

[0026] The transmission teeth 5 are used to mesh with the output shaft teeth of the motor inside the chassis 1. The rotating shaft 4 is located at the front of the chassis 1 and is arranged to rotate. The toothed belt and the motor inside the chassis 1 drive the two rotating shafts 4 to rotate.

[0027] The cross section of the transmission block 6 is hexagonal, and the transmission block 6 is located inside the rotating shaft 4 and is slidable. Due to the hexagonal shape, the transmission block 6 can slide inside the rotating shaft 4 and rotate synchronously with it.

[0028] The conduit 9 is movably installed inside the transmission block 6 and the cleaning plate 10. The rear end of the conduit 9 is used to be fixedly connected to the air pump inside the chassis 1. Through the connection between the air pump and the conduit 9, negative pressure is formed at the suction cup 12 to adsorb on the glass.

[0029] Specifically, through the connection of the transmission block 6, the rotating shaft 4 drives the cleaning disc 10 to rotate to clean the glass surface. The air pump in the chassis 1 is connected to the two conduits 9, and the alternating blowing and suction are controlled. The suction cup 12 forms a negative pressure and is adsorbed on the glass. The cleaning disc 10 is contracted by the contraction of the first spring 8, thereby improving the sealing of the suction cup 12 and the fixation of the chassis 1.

[0030] Example 2

[0031] See Figure 3 and Figure 4 , and on the basis of Example 1, it is further obtained that the sealing assembly 3 includes several support rods 13 and a fixing ring 14, the several support rods 13 are fixedly installed on the outside of the rotating shaft 4 near the front end, the fixing ring 14 is fixedly installed at the front of the several support rods 13, and several guide rods 15 are movably installed at the edge of the inside of the cleaning disc 10. A second spring 16 is installed on the periphery of the guide rods 15 and inside the cleaning disc 10. An annular groove 17 is opened at the front of the cleaning disc 10. The front ends of the several guide rods 15 are installed with the same fixing plate 18, and the front of the fixing plate 18 is installed with a sealing gasket 19.

[0032] The plurality of support rods 13 and the plurality of guide rods 15 are arranged in a ring-shaped manner. The guide rods 15 are located inside the cleaning disc 10 and are arranged to slide. The guide rods 15 automatically slide backward under the action of the second spring 16 .

[0033] The fixing plate 18 is fixedly mounted on the plurality of guide rods 15 , and the fixing plate 18 and the sealing gasket 19 are slidably arranged in the annular groove 17 . The contact between the sealing gasket 19 and the glass improves the sealing between the interior of the cleaning disc 10 and the interior of the suction cup 12 .

[0034] Specifically, the suction cup 12 is adsorbed on the glass, and the cleaning plate 10 slides backward, so that the rear end of the guide rod 15 contacts and presses against the fixing ring 14, and the interior of the cleaning plate 10 slides forward, so that the sealing gasket 19 slides out and contacts the glass, which can improve the sealing inside the cleaning plate 10, thereby improving the sealing of the suction cup 12 and strengthening the fixation between the chassis 1 and the glass.

[0035] During actual operation, the two cleaning discs 10 at the front end of the chassis 1 are placed on the glass surface of the window. The toothed belt and motor inside the chassis 1 drive the two cleaning discs 10 to rotate and clean the glass surface. This transmission principle refers to a wheel assembly device for a window cleaning robot disclosed in patent number CN211324675U. The air pump inside the chassis 1 is connected to the two conduits 9. The control system causes the suction cups 12 at the front ends of the two conduits 9 to alternately generate negative pressure to adsorb and fix the glass.

[0036] When cleaning and moving, the shaft 4 drives the cleaning disc 10 to rotate and clean through the connection of the transmission block 6. One of the suction cups 12 forms a negative pressure and is adsorbed on the glass. Under the action of the negative pressure, the cleaning disc 10 slides backward, and the suction cup 12 extends out of the suction groove 11 and contacts the glass. The first spring 8 contracts, and at the same time, the cleaning disc 10 rotates to continuously clean. The other suction cup 12 is separated from the glass, so that the two cleaning discs 10 clean at the same time. The two suction cups 12 alternately adsorb and automatically move and clean the glass surface.

[0037] When sealing, the cleaning disc 10 moves backward, so that the rear end of the guide rod 15 contacts the fixing ring 14 and presses forward to slide, so that the sealing gasket 19 is located in the ring groove 17 and extends out to contact the glass, thereby forming a seal inside the cleaning disc 10, improving the seal inside the suction cup 12, and stably fixing the chassis 1 on the glass. When the two suction cups 12 are alternately adsorbed, the cleaning disc 10 and the transmission block 6 automatically slide forward under the action of the first spring 8, and the guide rod 15 automatically slides backward under the action of the second spring 16, so that the sealing gasket 19 and the suction cup 12 are separated from the glass.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
