[0018] Please refer to the accompanying drawings for an embodiment of the present invention used in existing utility model patent 202420027289.5.

[0019] This utility model cleaning device is installed inside the soy milk container 2-2 of utility model patent 202420027289.5, as shown in the attached figure. Figure 2 As shown, the cleaning device includes nylon bristles 1-1, nylon rod 1-2, rotating shaft one 1-3, and rotating shaft two 1-4. Nylon rod 1-2 is cylindrical, with two rotating shafts, one upper and one lower, inside the cylinder. These shafts are fixed to nylon rod 1-2 with stainless steel screws 1-8 and 1-10, respectively. Nylon bristles 1-1 are fixed around the nylon rod. The lower rotating shaft one inside nylon rod 1-2 is connected to the blade assembly 2-6 inside the soy milk bucket 2-2. The upper rotating shaft two inside nylon rod 1-2 is connected to the lid 3-1 of the soy milk bucket 2-2 via a flat ball bearing 1-7 (the lid 3-1 is fixed with screws after it is closed). When the blade assembly 2-6 rotates, it drives nylon rod 1-2 to rotate. The nylon bristles 1-1 on nylon rod 1-2 scrub the inner wall of soy milk bucket 2-2, thus achieving the purpose of cleaning soy milk bucket 2-2.

[0020] The nylon rod 1-2 has many blind holes with different bevel angles. A bundle of multiple nylon hairs 1-1 is fixed in the blind holes by fasteners 1-6, forming multiple bundles of nylon hairs 1-1 arranged in an alternating pattern on the nylon rod 1-2.

[0021] The diameter of the nylon bristles 1-1 is 1-2 mm, and the total length of the nylon bristles on both sides of the nylon rod 1-2 is 10-30 mm greater than the diameter of the inner wall of the soy milk container 2-2.

[0022] The end of the rotating shaft has an internal hexagon blind hole, which is connected to the mounting nut 2-5 of the blade assembly 2-6 inside the soy milk bucket 2-2.

[0023] The second rotating shaft has a platform at its end, which is connected to a flat ball bearing 1-7. A silicone anti-collision screw 1-5 is connected to the outer side of the flat ball bearing 1-7. The end has an internal thread that assembles with the silicone anti-collision screw 1-5. The silicone surface of the silicone anti-collision screw 1-5 is pressed tightly against the lid of the soy milk container, as shown in the attached figure. Figure 3 As shown.

[0024] Cleaning start-up process:

[0025] Water begins to enter the soymilk maker through inlet 2-4. When the water volume reaches the automatically set capacity, the motor starts operating at the automatically set speed. The motor shaft drives the blades 2-6 to rotate, creating a water vortex that flows towards the container wall. The fastening nut 2-5 on the blades drives the rotating shaft, causing the cleaning device to rotate at high speed. The nylon bristles on the cleaning device generate centrifugal force during high-speed rotation, scraping the inner wall of the soymilk container 2-2. After the system-set time, the water inlet valve automatically opens to continue rinsing and scraping. Finally, the machine stops, the water inlet valve closes, and the drain valve opens to discharge the waste. This cycle repeats twice, thoroughly cleaning the inside of the soymilk maker container, saving time and effort and improving its efficiency.
