[0027] The cleaning assembly 11 includes a scraper ring 111, the outer side of the scraper ring 111 contacts the inner wall of the distillation box 1, the back of the inner wall of the scraper ring 111 is fixedly connected to a connecting block 112, the top of the connecting block 112 is fixedly connected to a push-pull rod 113, the top of the push-pull rod 113 is fixedly connected to the bottom output end of the electric push rod 3, a rotating rod 12 is provided inside the distillation box 1, and a plurality of connecting rods 123 are fixedly connected to the outer surface of the bottom of the rotating rod 12, and a plurality of connecting rods 123 are fixedly connected to a scraper 124 on the side away from the rotating rod 12, and a conical ring is fixedly connected to the inner wall of the distillation box 1 13. By setting up the cleaning component 11, specifically when discharging, the electric push rod 3 is started to drive the connecting block 112 to move downward through the push-pull rod 113, and the connecting block 112 will drive the scraper ring 111 to move downward, and the scraper ring 111 will scrape off the material remaining on the inner wall of the distillation box 1, so that the material can be discharged more thoroughly. At the same time, the conical ring 13 can play a role in diversion, and further reduce the residue. At the same time, when the rotating rod 12 rotates, it will drive the scraper rod 124 to rotate through the connecting rod 123, and the scraper rod 124 will scrape off the material remaining on the surface of the conical ring 13, thereby improving the unloading rate.

[0028] The top of the rotating rod 12 is rotatably connected to the distillation box 1, and the top of the rotating rod 12 is fixedly connected to the bottom output end of the motor 2. The outer surface of the rotating rod 12 is fixedly connected to a pentagonal ring 121, and the outer surface of the pentagonal ring 121 is fixedly connected to a plurality of stirring rods 122. The surface of the scraper rod 124 contacts the surface of the conical ring 13. When the motor 2 is started to drive the rotating rod 12 to rotate, the rotating rod 12 drives the plurality of stirring rods 122 to rotate through the pentagonal ring 121 to stir and distill the material inside the distillation box 1.

[0029] The bottom of the rotating rod 12 is fixedly connected to a vibration ring 14, and a conical fixing block 141 is provided below the vibration ring 14.

Since the sides of the protrusion 143 and the collision block 441 close to each other are both set as arc surfaces, the protrusion 143 can smoothly push the collision block 441.

[0033] A specific application of this embodiment is:

[0034] After scraping, the electric push rod 3 drives the connecting block 112 to move upward through the push-pull rod 113 to reset the scraper ring 111. At the same time, when the rotating rod 12 rotates, it drives the scraper rod 124 to rotate through the connecting rod 123. The scraper rod 124 is driven to rotate. The material remaining on the surface of the conical ring 13 is scraped off, thereby improving the unloading rate. When the rotating rod 12 rotates, the vibrating ring 14 will rotate accordingly, and the vibrating ring 14 will drive the collision block 441 to rotate together. When the collision block 441 contacts the protrusion 143, a collision effect will occur, thereby generating vibration, and at the same time, the collision block 441 will be pushed into the movable groove 144. At the same time, the sliding rod 442 slides on the vibrating ring 14 and squeezes the spring 443, so that the collision block 441 can pass through the protrusion 143 smoothly.

There is no need for staff to clean it many times, reducing labor.
