[0024] The other end of the top surface of the substrate 1 of the example is rotatably provided with a supporting roller 2, and the supporting roller 2 is symmetrically distributed about the center of a vertical threaded rod 3. The above structure can stably support vacuum rollers of different sizes and cooperate with the structure provided on the vertical threaded rod 3 to stably clean.

[0025] The vertical threaded rod 3 is slidably connected to the holes provided at the ends of the first mounting plate 4 and the second mounting plate 5. The first mounting plate 4 and the second mounting plate 5 are of the same size. The above structure enables the first mounting plate 4 and the second mounting plate 5 to stably vertically slide along the vertical threaded rod 3, adjust the working position, and enable the inner working box 8 and the outer working box 13 to adapt to vacuum rollers of different sizes.

[0026] The first locking nut 6 and the second locking nut 7 are symmetrically distributed about the center of the first mounting plate 4 and the second mounting plate 5. The diameters of the first locking nut 6 and the second locking nut 7 are greater than half the width of the first mounting plate 4 and the second mounting plate 5.

[0032] Then control the three-section electric telescopic rod 10 to extend, the three-section electric telescopic rod 10 pushes the supporting plate 11 to move downwards until the bottom surface of the supporting plate 11 is stably attached to the inner bottom surface of the vacuum roller, control the three-section electric telescopic rod 10 to be stationary, improve the stability of the inner working box 8 during work, start the high-pressure water pump connected to the high-pressure spray head 9, and the water flow is sprayed at high speed from the high-pressure spray head 9 to flush the air extraction hole at the top of the vacuum roller inside the inner working box 8, and the water carrying impurities enters the outer working box 13 and is quickly sucked and transferred by the suction mechanism connected to the suction pipe 15;

[0033] After the single position flushing is completed, only need to rotate the first locking nut 6 and the second locking nut 7 slightly away from the upper and lower end faces of the end of the first mounting plate 4 and the second mounting plate 5, the top sealing ring 12 and the bottom sealing ring 14 are slightly separated from the inner and outer walls of the vacuum roller, and the vacuum roller is rotated on the supporting roller 2 to change the position of the inner working box 8 and the outer working box 13, and the above operation is repeated to flush the vacuum roller on the same vertical surface, after the flushing of the vacuum roller on the same vertical surface is completed, the vacuum roller can be pushed to move horizontally until the entire vacuum roller is flushed, which is the working principle of the vacuum roller body air extraction hole cleaning device.
