[0038] Please see the appendix Figure 3 - Appendix Figure 5 A battery 24 is fixedly connected to the left rear end of the extraction box 1, and a vent 25 is provided on the right rear end of the extraction box 1. A cover plate 22 is rotatably connected to the top of the liquid storage tank 3, and a handle 26 is fixedly connected to one side of the cover plate 22.

[0039] Specifically, a battery 24 is fixedly installed on the left rear end of the extraction box 1 via a fixed connection. This battery 24 is securely installed on the left rear end of the extraction box 1 to ensure its stability and safety. A vent 25 is provided on the right rear end of the extraction box 1.

[0040] Working principle: During use, the cleaning solution stored on the left side of the storage tank 3 is released through valve 5, and a certain amount of cleaning solution flows into the extraction tank 10 through the inlet pipe 4. The motor 21 is started, which drives the drive wheel 16 to rotate, which in turn drives the drive wheel 9 to rotate through the drive bar 8. The rotation of the drive wheel 9 drives the stirring rod 18 and the stirring bar 17 fixed on the stirring rod 18 to rotate, thereby cleaning the extraction tank 10. After cleaning, the blockage block 12 is removed and the wastewater is discharged through the outlet 11. After discharge, the blockage block 12 is put back in its original position, and the water stored on the right side of the storage tank 3 is used to clean the extraction tank 10 again in the same way, so as to achieve a more thorough cleaning of the extraction tank 10 and avoid affecting the next extraction.

[0041] In use, the starter motor 208 drives the gear 203 to rotate via the drive rod 202. The rotation of the gear 203 drives the feed pipe 207 to move up and down in the sliding groove 205 via the teeth 204 and the sliding block 206 fixed at the other end of the feed pipe 207. This moves the feed pipe 207 to a predetermined position. When a certain amount of raw material is put into the feed inlet, the baffle 210 moves upward in the sliding groove 209 due to buoyancy and blocks the feed pipe 207, thereby achieving the function of putting in a certain amount of raw material.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
