The other end of the table wiping sleeve 13 is arranged on the mounting hole on the L-shaped box body frame 2 on the corresponding side through a table wiping sleeve fixing end 13a.

When the dining table works, referring to fig. 2 and 4, in an initial state, the spring 3 is in a free state, the L-shaped box frame 2 is located at the lowest position, the bottom end of the L-shaped box frame 2 extends to the lowest position of the hollowed square groove of the L-shaped support 7, at the moment, the vertical distance between the outer rotor motor 5 and the bottom end of the table wiping piece 15 is shortest, the table top is located between the outer rotor motor 5 and the bottom end of the table wiping piece 15, and the table wiping piece 15 is tightly attached to the upper surface of the table top. In the initial state, the telescopic rod spring 14 is in a free extension state, the length of the telescopic rod 12 is shortest, and the distance between the L-shaped box frames 22 at the left end and the right end is shortest.

Referring to fig. 2 and 4, when the width of the dining table to be cleaned is greater than the width of the dining table in the initial state, the left hand and the right hand respectively hold the hand rings 2e on the L-shaped case frames 2 at the left side and the right side at the moment, the L-shaped case frames 2 are stretched towards the left side and the right side, the distance between the casters 4 at the left side and the right side is increased, the casters 4 are matched with the two outer side walls of the table top, at the moment, the table wiping sheet 15 sleeved in the table wiping sleeve 13 extends outwards for lengthening, the spray pipe 10 sleeved in the spray pipe sleeve 16 extends outwards for lengthening, and the telescopic rod 12 overcomes the tensile force extension of the telescopic rod spring 14 to adapt to the larger width of the. When the thickness of dining table when will wasing is greater than the dining table thickness when initial condition, the bracelet 2e on the L type box frame 2 of both sides about artifical is held respectively to the hand about this moment, upwards promotes L type box frame 2, and L type box frame 2 overcomes the pulling force of spring 3 upwards, makes the distance increase between the top of external rotor motor 5 and the bottommost end of wiping sheet 15, wipes sheet 15 and hugs closely the upper surface of dining table face to adapt to thicker dining table thickness.

Referring to fig. 1 and 4, after the casters 4, the outer rotor motor 5 and the table wiping sheet 15 are adjusted, the switch 9 is pressed, the outer rotor motor 5 works, the whole cleaning mechanism is driven to move longitudinally forward and backward on the dining table by the rolling of the left and right outer rotor motors 5 on the lower surface of the dining table top, and the casters 4 on the left and right sides on the outer side wall of the dining table top roll longitudinally forward and backward. Referring to fig. 2 and 5, during the movement, a spray pipe 10 located in front of the movement direction sprays the cleaning liquid onto the table top, and the spray pipe 10 operates with a pump 11 in the corresponding cleaning liquid tank 1 to press the cleaning liquid into the corresponding spray pipe sleeve 16 and spray pipe 10, and the cleaning liquid is sprayed from the spray holes 10b of the spray pipe 10 onto the table top. Then, the table wiping sheet 15 and the table wiping sleeve 13 push the greasy dirt on the table top and the cleaning solution forward in the same direction. When the cleaning liquid box moves to the foremost rear end of the dining table, the distance sensor 8 senses the change of the distance between the distance sensor 8 and the lower end surface of the dining table when the distance sensor 8 crosses the front end surface and the rear end surface of the dining table, whether the cleaning liquid box is positioned at the edge of the dining table or not is judged, at the moment, the outer rotor motor 5 rotates reversely, the cleaning liquid box is controlled to move in the opposite direction, meanwhile, the pump 11 which is in work stops working, the pump 11 in the other cleaning liquid box 1 starts to work, and the cleaning liquid is still sprayed in the moving direction. The dining table top is repeatedly cleaned in a circulating way until the dining table top is cleaned, and the switch 9 is closed.
