The elastic element 304 is fitted onto the guide rod 303, one end of the elastic element 304 abuts against the baffle 301, and the other end abuts against the bracket 302. The scraper 610 is adapted to move close to the drain outlet 101 so as to push the baffle 301 out of the drain outlet 101. A sealing element is provided at the connection between the baffle 301 and the drain outlet 101. The treatment tank is provided with two drain outlets 101, and each drain outlet 101 is provided with a shielding component 3 to facilitate the discharge of impurities. See also Figure 1 If the rod 609 passes through the baffle 301, the rod 609 and the baffle 301 are slidably connected, and a seal is provided at the connection. The scraper 610 is provided with corresponding protrusions, which abut against the baffle 301, pushing the baffle 301 to open the drain port 101, allowing impurities to be discharged. After the scraper 610 moves away from the baffle 301, it is closed by the force of the elastic element 304. All of the above seals can be rubber sealing rings.

[0028] In some embodiments, a collection box 5 is also included, which is disposed below the drain outlet 101. A first drive member 606 and a cleaning transmission member are mounted on the collection box 5. The collection box 5 is used to contain impurities discharged from the drain outlet 101.

[0029] In some embodiments, the filtration unit 4 includes a first filter plate 401, a second filter plate 402, and an activated carbon layer 403. The activated carbon layer 403 is disposed between the first filter plate 401 and the second filter plate 402. The first filter plate 401 is arranged corresponding to the first pool body, and the second filter plate 402 is arranged corresponding to the second pool body.

A fixing frame 9 is installed on the treatment tank 1, and a second driving member 10 is provided on the fixing frame 9. The output shaft of the second driving member 10 is provided with a driving gear 11 that meshes with the rack 8. When the second driving member 10 is started, the driving gear 11 rotates, causing the activated carbon layer to move and disengage from the first filter plate 401 and the second filter plate 402, thereby realizing the replacement of the activated carbon layer. On the other hand, the support frame 7 is placed between the first filter plate 401 and the second filter plate 402, so that the activated carbon layer is installed in the support frame 7. The above arrangement is beneficial for the replacement of the activated carbon layer 403.

The cleaning drive assembly is adapted to make the cleaning component 611 perform a scraping action on the filter plate. The treatment tank 1 is inclined, and the bottom surface of the first tank is higher than the bottom surface of the second tank.

[0035] The treatment tank 1 has a drain outlet 101 on its side wall, which is correspondingly arranged with the scraper 610. The drain outlet 101 is provided with a shielding component 3 to block or open the drain outlet 101. The shielding component 3 includes a baffle 301, a bracket 302, a guide rod 303, and an elastic element 304. The baffle 301 is installed inside the drain outlet 101, the bracket 302 is installed on the treatment tank 1, one end of the guide rod 303 is fixedly connected to the baffle 301, and the other end is slidably connected to the bracket 302.
