[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the specific implementation method is as follows: the side of the drive motor 7 is bolted to the side of the water tank 2, and the drive motor 7 is located on the side of the water tank 2 near the top. The mounting frame 8 is bolted to the inner wall of the top of the water tank 2, and the lead screw 9 is mounted in the middle of the mounting frame 8 through a bearing. The output end of the drive motor 7 is connected to the lead screw 9 for transmission. The top of the mounting frame 8 has a groove 19, and a slider 10 is slidably connected inside the mounting frame 8. The slider 10 is sleeved on the outer wall of the lead screw 9, and the slider 10 is connected to the lead screw 9 through threads. A connecting frame 11 is fixedly connected to the side of the slider 10. There are two connecting frames 11, which are symmetrically distributed on both sides of the slider 10. A T-shaped limiting slide rail 17 is fixedly connected to the side of the connecting frame 11 near the mounting frame 8.

The bottom of the connecting plate 14 is bolted with a cleaning scraper 20, which contacts the bottom inner wall of the water tank 2. The drive motor 7 drives the screw 9 inside the mounting frame 8 to rotate, causing the slider 10 to move the L-shaped support frame 13 and the connecting plate 14 along the screw 9. During the movement, the connecting plate 14 drives the cleaning brush 15 and the cleaning scraper 20 to clean the impurities accumulated on the inner wall of the water tank 2, preventing the accumulation of impurities from affecting the service life of the water tank 2. Moreover, it eliminates the need for manual cleaning by staff, improving the ease of use of the device.

[0024] The connecting frame 11 is connected to the L-shaped support frame 13 by positioning bolts 16. The L-shaped support frame 13 is snapped into the inside of the connecting frame 11, which facilitates the disassembly of the L-shaped support frame 13. At the same time, a T-shaped limiting slide rail 17 is installed on the side of the connecting frame 11. The T-shaped limiting slide rail 17 is slidably connected to the limiting slide groove 18 on the side of the mounting frame 8, thereby improving the stability of the connecting frame 11.
