Detailed Description

The present invention will now be described in detail with reference to the accompanying drawings, as shown in fig. 1 to 5.

When the motor 2 is powered on, the driving gear 1 is driven, and then the driven gear 4, the rotating support beam 5 fixed on the driving gear, the inner wiping frame 8, the outer wiping frame 6 and the wiping rubber strip 10 are driven to rotate around the axis pillar 13 of the rotating hyperboloid (specifically, see the schematic diagrams of fig. 1 and 3), when the inner wiping frame 8 rotates, the inner wiping frame abuts against the circular rods at the two ends of the limiting plate rod 7 to limit one side inclined plane (specifically, see the schematic diagram of fig. 3 for a partially enlarged view 5), on one hand, the limiting plate rod 7 is pushed and driven to rotate together, on the other hand, the side inclined plane of the limiting plate rod 7 is limited (specifically, see the schematic diagram of fig. 3 for a partially enlarged view 5) to force the inner wiping frame 8 to automatically slightly deflect towards the rotating center, so that the wiping rubber strip 10 on the inner wiping frame 8 abuts against the inner rotating curved surface 12 to be cleaned; meanwhile, the inner rotating curved surface 12 forms an outward downward reaction force (specifically, see the schematic section of the left middle part in fig. 1) on the inner wiping frame 8 through the wiping rubber strip 10, so that the rotating corbel 5 and the outer wiping frame 6 are both deflected outward and downward, and the rotating centrifugal force is added, so that the wiping rubber strip 10 on the outer wiping frame 6 is wiped against the outer rotating curved surface 11 to be wiped, and thus, the automatic wiping and brushing of the inner rotating curved surface 12 and the outer rotating curved surface 11 can be simultaneously realized. After the motor 2 is powered off, under the action of the pulling force of the return spring 9 and the gravity of the limiting plate rod 7, the rotating corbel 5, the inner wiping frame 8 and the outer wiping frame 6 can automatically return to the original positions (specifically, see the schematic diagrams of fig. 1 and 2), so that the wiping rubber strip 10 can be far away from the inner rotating curved surface 12 and the outer rotating curved surface 11 to be cleaned.
