[0022] Among them, the design of the annular box cover 2 being threadedly connected to the mixing box 1 makes it convenient for the staff to quickly open the mixing box 1. The cross 6 is used to support the cleaning components and mixing device in the inner cavity of the mixing box 1. The motor 3 is used to drive the stirring shaft 7 to drive the stirring rod 8 and the cleaning component to rotate, which is convenient for automatic mixing and automatic cleaning of the inner cavity. The water tank 5 is designed to hold water used for cleaning, so as to facilitate automatic cleaning of the device.

[0023] like Figure 3 and Figure 4 As shown, the cleaning assembly includes multiple groups of support rods 9 fixedly connected to the top of the surface of the stirring shaft 7, and a pull-out rod 10 is slidably inserted in each group of support rods 9. Slots 12 are provided on both sides of the top of the pull-out rod 10, and a joint 11 is fixedly installed on one side of the surface of the support rod 9. The top of one side of the joint 11 is fixedly connected to an extension plate 13, and a T-shaped plug 14 is inserted on the extension plate 13. The bottom end of the T-shaped plug 14 is inserted into the corresponding slot 12, and a spring 15 is fixedly connected to the side where the protruding ends of the extension plate 13 and the T-shaped plug 14 are close to each other, and the spring 15 is sleeved on the T-shaped plug 14, one end of the pull-out rod 10 is fixedly connected to a scraper 16, and one side of the scraper 16 is attached to the inner wall of the mixing box 1, and a telescopic rod 17 is fixedly connected to the bottom of the side where the scraper 16 and the stirring rod 8 are close to each other.

[0024] Specifically, the support rod 9 is used to fix and support the component, and the pull-out rod 10 is stretched out from the support rod 9 to drive the scraper 16 to stick to the inner wall of the mixing box 1. The T-shaped insert rod 14 is stuck into the slot 12 under the elastic force of the spring 15, thereby locking the stretched pull-out rod 10 to ensure that the scraper 16 sticks to the inner wall of the mixing box 1; the stirring shaft 7 is driven by the motor 3, and the scraper 16 is rotated on the inner wall of the mixing box 1 to clean the inner wall of the mixing box 1.

[0025] like Figure 2 and Figure 3 As shown, an annular connecting frame 18 is fixedly connected to one side of the top of the cross 6 close to the inner wall of the mixing box 1, and the inner side of the annular connecting frame 18 is connected to multiple groups of water pipes 20, and one end of the water pipe 20 is connected to the built-in annular flow channel of the circular plate 19.
