The cleaning kettle 1 is provided with a spiral tube 6, and the four circular tubes 3 4 are all sleeved with springs. The four circular tubes 3 4 are restored to their original state by the action of the four springs.

[0032] In this embodiment, a cavity is formed on each of the two scrapers 5, and one end of each of the four circular tubes 4 is connected to the two cavities respectively. A plurality of through holes are formed on each of the two scrapers 5, and the plurality of through holes are connected to the two cavities respectively, so as to facilitate the discharge of water and hot air and act on the inner wall of the cleaning kettle 1.

[0033] In this embodiment, the driving mechanism includes a square sleeve 7, a water pump 8, a hot air blower 11 and a motor 14. The square sleeve 7 is fixedly connected to the cleaning kettle 1, and the water pump 8 is fixedly installed in the square sleeve 7. One end of the water pump 8 is sealed with a water pipe 9, and one end of the water pipe 9 is sealed with a three-way pipe. The three-way pipe is sealed with a round tube four 10, and one end of the round tube four 10 is rotatably connected to the round tube one 2. The water pump 8 is connected to the control module 17, and is used to transport water in the cleaning mechanism to achieve the effect of flushing the organic acid in the cleaning kettle.

[0034] In this embodiment, the hot air blower 11 is fixedly installed on the square sleeve 7, and is sealed with an air pipe 12 and an air pipe 2 13. One end of the air pipe 12 is sealed with the spiral tube 6, and one end of the air pipe 2 13 passes through the square sleeve 7 and is connected to the three-way pipe. The hot air blower 11 is connected to the control module 17 to transport hot air into the cleaning mechanism, thereby cleaning the residual water in the cleaning kettle 1 and improving the product quality.

[0035] In this embodiment, the motor 14 is fixedly installed in the square sleeve 7, and the output end of the motor 14 is fixedly connected to the gear 15, and the gear 15 is meshed with a gear ring 16, and the gear ring 16 is fixedly sleeved on the round tube 2. The motor 14 is connected to the control module 17, which is used to drive the cleaning mechanism, so that the cleaning mechanism can clean the inside of the cleaning kettle 1. At the same time, the liquid can be stirred through the action of multiple stirring rods on the round tube 2.

[0036] In this embodiment, solenoid valves are provided on the gas pipe 13 and the water pipe 9, and both solenoid valves are connected to the control module 17 for controlling the flow of water and hot air.

[0037] In this embodiment, a sealing bearing is fixedly sleeved on the circular tube 4 10, and the outer wall of the sealing bearing is fixedly connected to the circular tube 1 2, so as to facilitate the transportation of water and hot air in the circular tube 1 2 on the circular tube 4 10 and the rotation of the circular tube 1 2.

[0038] Working principle: When in use, the water pump 8, the hot air blower 11 and the motor 14 are controlled and driven by the control module 17, and the two solenoid valves are controlled to switch;

[0039] By driving the water pump 8 and opening the solenoid valve on the water pipe 9, water is transported to the circular tube 1 2 through the water pipe 9, the three-way pipe and the circular tube 4 10. At the same time, the water is transported to the four circular tubes 2 3 through the four through holes on the circular tube 1 2, thereby increasing the water pressure in the four circular tubes 2 3. At the same time, the water pressure acts on the four sealing rings 18, so that the four circular tubes 3 4 and the sealing rings 18 slide in the four circular tubes 2 3 respectively and the four springs are compressed. At the same time, the four circular tubes 3 4 drive the two scrapers 5 to move synchronously, and the two scrapers 5 are in contact with the inner wall of the cleaning kettle 1. At the same time, water enters the two scrapers through the four circular tubes 3 4. 5 and discharged through multiple through holes, thereby achieving the effect of flushing the organic acid in the cleaning kettle 1; at the same time, the gear 15 is driven by the motor 14 to rotate and transmit to the gear ring 16, and the gear ring 16 drives the round tube 2 to rotate on the cleaning kettle 1. At the same time, the round tube 2 is driven by the four round tubes 2 3 and the round tube 3 4, so that the two scrapers 5 rotate, thereby achieving the effect of fully flushing the organic acid in the cleaning kettle 1, and also achieving the effect of cleaning the impurities adhering to the inner wall of the cleaning kettle 1, and the multiple stirring rods on the round tube 2 can also achieve the effect of stirring the liquid in the cleaning kettle 1;

[0040] After the cleaning kettle is flushed, the water in the cleaning kettle 1 is discharged through the discharge pipe at the bottom of the cleaning kettle 1, and then the battery valve on the water pipe 9 is closed and the battery valve on the air pipe 13 is opened and the hot air blower 11 is driven. The hot air is driven by the hot air blower 11 to enter the spiral tube 6 and the round tube 1 2 through the air pipe 1 12 and the air pipe 2 13 respectively. In this process, the hot air heats the inner wall of the cleaning kettle 1 through the action of the spiral tube 6, thereby increasing the temperature in the cleaning kettle 1, thereby evaporating the water in the cleaning kettle 1.

[0041] At the same time, through the action of the four circular tubes 2 3 and the circular tube 3 4, the hot air enters the two cavities on the two scrapers 5 and is discharged through multiple through holes, thereby achieving the effect of further cleaning the water in the cleaning kettle 1. At the same time, through the drive of the motor 14, the two scrapers 5 scrape the water on the inner wall of the cleaning kettle 1, thereby achieving the effect of accelerating the drying of the inside of the cleaning kettle.

[0042] The technical progress achieved by the utility model compared with the prior art is that the organic acid and impurities in the cleaning kettle 1 can be cleaned through the cooperation of various components, and the residual water in the cleaning kettle 1 can also be cleaned, thereby improving product quality and work efficiency, and the structure is simple and more practical.
