[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 Figure 1-Figure 4 A cleaning structure of a circular window cleaning machine includes a chassis 1, a disassembly and assembly mechanism 2 is installed on the front of the chassis 1, and a protective mechanism 3 is installed on the outer ring of the disassembly and assembly mechanism 2.

[0025] See Figure 2 and Figure 3 , it is further obtained that the disassembly and assembly mechanism 2 includes two turntables 4 and two cleaning discs 6. The two turntables 4 are respectively mounted on the motor output shaft of the chassis 1. A number of positioning slots 5 are opened at the front of the turntable 4, and a number of through holes 7 are opened through the front and rear ends of the cleaning disc 6. A number of positioning blocks 8 are fixedly installed at the rear of the cleaning disc 6. A soft cover 9 is fixedly connected to the side of the rear of the cleaning disc 6. A rubber ring 10 is inserted into the inside of the soft cover 9. A brush layer 11 is pasted on the front of the cleaning disc 6.

[0026] The turntable 4 is fixedly connected to the motor output shaft in the chassis 1 , and the cleaning disc 6 is installed in front of the turntable 4 to match each other. The cleaning disc 6 is clamped in the front of the turntable 4 and driven to rotate by the turntable 4 .

[0027] The plurality of positioning grooves 5 and positioning blocks 8 are arranged in a ring-shaped manner. The positioning blocks 8 and the positioning grooves 5 are engaged with each other. The engagement of the positioning blocks 8 and the positioning grooves 5 allows the cleaning disc 6 to rotate synchronously with the turntable 4 .

[0028] The soft sleeve 9 is sleeved on the outside of the turntable 4 and is matched with each other. The diameter of the rubber ring 10 is smaller than the outer ring diameter of the turntable 4. The soft sleeve 9 is sleeved on the outside of the turntable 4. The cleaning disc 6 is tightly attached to the turntable 4 and fixed by stretching the rubber ring 10.

[0029] Specifically, the cleaning disc 6 is installed on the front of the turntable 4, so that the positioning block 8 is stuck in the positioning groove 5, and at the same time the soft cover 9 is sleeved on the outside of the turntable 4. The rubber ring 10 shrinks under the stretching action, so that the cleaning disc 6 is tightly attached to the turntable 4 and fixed, which facilitates the quick installation and removal of the cleaning disc 6.

[0030] Example 2

[0031] See Figure 4On the basis of Example 1, it is further obtained that the protective mechanism 3 includes a protective sleeve 12 and a rail 13, the rail 13 is fixed around the outer ring of the cleaning disc 6, the protective sleeve 12 is movably installed on the outside of the cleaning disc 6, the inner ring of the protective sleeve 12 is provided with a ring groove 14, and the outer ring of the protective sleeve 12 is provided with a rubber sleeve 15.

[0032] The rail 13 is located on the outer ring of the cleaning disc 6 and is arranged in a circular shape. The rubber sleeve 15 is fixedly sleeved on the outer ring of the protective sleeve 12 . The rubber sleeve 15 is used to provide a buffer for the outer ring of the cleaning disc 6 .

[0033] The clamping rails 13 are located in the annular grooves 14 and match each other. The protective sleeve 12 is sleeved on the outside of the cleaning disc 6 and is movably rotatable. The clamping rails 13 can rotate the protective sleeve 12 while preventing it from falling off.

[0034] Specifically, when the cleaning disc 6 collides with a window frame or a protruding building, the rubber sleeve 15 provides a buffer to reduce the collision force. The cleaning disc 6 rotates and cleans during the collision, and the friction on the outer ring of the cleaning disc 6 is reduced by the rotation of the protective sleeve 12.

[0035] During actual operation, the cleaning disc 6 is installed in front of the turntable 4, and the turntable 4 is driven to rotate by the motor inside the chassis 1. The air pump inside the chassis 1 creates negative pressure in front of the cleaning disc 6 through the through hole 7, so that it is adsorbed on the window to be fixed and moved, and the surface of the window is cleaned by the brush layer 11;

[0036] When installing, replacing and cleaning the brush layer 11 after cleaning, the cleaning disc 6 is located in front of the turntable 4, the positioning block 8 is inserted into the positioning groove 5, and the soft cover 9 is sleeved on the outside of the turntable 4. The rubber ring 10 shrinks under the action of tension, so that the cleaning disc 6 is tightly attached to the turntable 4 and fixed. The cleaning disc 6 is disassembled by removing the soft cover 9;

[0037] When the cleaning disc 6 collides with the window frame or protruding building during the cleaning process, the rubber sleeve 15 provides a buffer for the cleaning disc 6. During the cleaning process of the cleaning disc 6 rotating, the rubber sleeve 15 contacts the window frame or protruding building, and the friction on the cleaning disc 6 is reduced by the rotation of the protective sleeve 12.

[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.
