[0030] When the cleaning structure is in use, it is first connected to the external water supply device through the connecting disk 27, and then the storage tank is placed on the rotating plate 3, and then the power is turned on to start the external water supply device. The water supply device will transport water to the inside of the connecting rod 9, and then the water will be sprayed onto the inner wall of the storage tank through the water spray pipe 26, and then the servo motor 4 is started.
