Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when the drive motor 703 is started, the drive motor 703 drives the guide plate 701 to rotate through the rotating shaft 702. Since there are multiple sets of guide plates 701, which are fixed to the outside of the rotating shaft 702 in a ring with equal spacing, the rotating shaft 702 drives the guide plate 701 to rotate, so that the medicine inside the material box 1 can enter the inside of the discharge pipe 9 at a uniform speed, and then fall to the right side of the water inlet pipe 12 through the discharge pipe 9. Then, it spreads to the whole pool with the water flow at the water inlet pipe 12. The uniform discharge of medicine can not only prevent the medicine from clogging inside the discharge pipe 9, but also prevent the medicine from accumulating due to excessive discharge.

The locking blocks 804 are embedded in the inside of the locking grooves 806. The locking blocks 804 are fixed in the inside of the locking grooves 806 through the limit grooves 805 and the limit rods 803. The limit springs 802 are provided at the front end of the limit rods 803. Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the feed pipe 9 is easily damaged when immersed in the treatment tank 10 for a long time. When the feed pipe 9 needs to be disassembled and replaced, pull the pull plate 801. The pull plate 801 moves the limit rod 803, causing the locking block 804 to lose its fixation. With the locking block 804 no longer fixed, the feed pipe 9 can be disassembled and replaced. Place the new feed pipe 9 at the bottom of the feed port 4. When placing the feed pipe 9, make the locking block 804 at the top of the fixing frame 13 embedded in the slot 806. Release the pull plate 801. The limit spring 802 uses its own elasticity to make the limit rod 803 re-embed in the limit groove 805 to limit and fix the locking block 804, thus completing the replacement of the feed pipe 9.

Specifically, such as Figure 1 and Figure 4 As shown, the cover plate 2 is fixed to the top of the material box 1. When the inside of the material box 1 needs to be cleaned, the spring plate 302 is pressed. When the spring plate 302 drives the limiting groove 304 to disengage from the inside of the limiting protrusion 303, the connecting block 301 loses its fixation. When the connecting block 301 loses its fixation, the cover plate 2 can be removed from the top of the material box 1. Removing the cover plate 2 makes it convenient to clean the inside of the material box 1.

The drive motor 703 is started, and the drive motor 703 drives the guide plate 701 to rotate through the rotating shaft 702. Because the guide plate 701 Multiple sets of guide plates are fixed to the outside of the rotating shaft 702 in a ring with equal spacing. The rotating shaft 702 drives the guide plate 701 to rotate, so that the medicine inside the material box 1 can enter the inside of the discharge pipe 9 at a uniform speed. Then, it falls to the right side of the water inlet pipe 12 through the discharge pipe 9, and then spreads to the whole pool with the water flow at the water inlet pipe 12. The uniform discharge of medicine can not only prevent the medicine from clogging inside the discharge pipe 9, but also prevent the medicine from accumulating due to excessive discharge. The cover plate 2 is fixed to the top of the material box 1. When it is necessary to clean the inside of the material box 1, the spring plate 302 is pressed. When the spring plate 302 drives the limiting groove 304 to disengage from the inside of the limiting protrusion 303, the connecting block 301 loses its fixation. When the connecting block 301 loses its fixation, the cover plate 2 can be removed from the top of the material box 1. Removing the cover plate 2 makes it convenient to clean the inside of the material box 1.
