[0049] The physical filter chamber 103 in the embodiment of the present application is provided with a physical filter cotton 9 for physically filtering water; the biochemical filter chamber 104 is used to place biochemical filter materials for biochemical bacterial cultivation, and the filtering effect can be ensured by physically filtering and biochemically filtering water. The embodiment of the present application does not specifically limit the installation method of the physical filter cotton 9, and the periphery of the physical filter cotton 9 can be connected to the inner wall of the physical filter chamber 103 to ensure that there is a gap between the two side surfaces (the first side surface and the second side surface) of the physical filter cotton 9 and the inner wall (the first inner wall and the second inner wall) of the physical filter chamber 103. Figure 3 A three-dimensional diagram of the physical and biochemical filtration chamber provided in the embodiment of the present application, Figure 4 A side view of the physical and biochemical filtration chamber provided in an embodiment of the present application, Figure 5 The bottom view of the physical and biochemical filtration chamber provided in the embodiment of the present application is as follows: Figures 3 to 5As shown, the physical filter chamber 103 and the biochemical filter chamber 104 can be arranged side by side, and the first water inlet 3 can be arranged on the side wall at the bottom of the physical filter chamber 103, and the first water outlet 4 can be arranged on the side wall at the bottom of the biochemical filter chamber 104; the water pump chamber 2 and the physical and biochemical filter chamber 1 can also be arranged side by side, the second water inlet 5 is arranged at the bottom of the water pump chamber 2, connected to the first water outlet 4, and the second water outlet 6 can be arranged at the top of the water pump chamber 2.

Under the action of the water pump chamber 2, the direction of the water flow is: entering the first gap from the first water inlet 3, the water flow penetrates from the first side of the physical filter cotton 9 to the second side for physical filtration, and then enters the second gap, passes through the through hole on the partition 11, enters the biochemical filter chamber 104 for biochemical filtration, and then the water pump chamber 2 pumps the filtered water into the cylinder 23.

[0050] A filtering device provided by the embodiment of the present application includes: a physical biochemical filtering chamber and a water pump chamber; a partition is provided in the physical biochemical filtering chamber to separate the physical biochemical filtering chamber into a physical filtering chamber and a biochemical filtering chamber, a physical filter cotton is provided in the physical filtering chamber, a first gap exists between the first side of the physical filter cotton and the first inner wall of the physical filtering chamber, a second gap exists between the second side of the physical filter cotton and the second inner wall of the physical filtering chamber, a first water inlet is provided on the side wall of the physical filtering chamber between the first side and the first inner wall so that the first water inlet is connected to the first gap, a through hole is provided on the partition between the second side and the second inner wall, the biochemical filtering chamber is connected to the second gap through the through hole, the biochemical filtering chamber is provided with a first water outlet, the water pump chamber is provided with a second water inlet and a second water outlet, and the second water inlet is connected to the first water outlet. Since the water flow always passes through the first side of the physical filter cotton, the second side of the physical filter cotton, the biochemical filtering chamber and the water pump in sequence, the water flow direction has directional characteristics, which improves the ability of the physical filter cotton to block impurities, can ensure sufficient filtration of the filtering device, and improve the filtering effect. In addition, the combination of physical filtration and biochemical filtration can further ensure the filtration effect.

[0051] Based on the above embodiments, Figure 6 This is an exploded view of the first physical and biochemical filtration chamber provided in the embodiment of the present application. Figure 7 The exploded diagram of the second physical and biochemical filtration chamber provided in the embodiment of the present application is as follows: Figure 6 and Figure 7 As shown, the first inner wall and the second inner wall of the embodiment of the present application are both provided with supporting protrusions, which respectively abut against the first side and the second side of the physical filter cotton 9 to form a first gap between the first side and the first inner wall, and a second gap between the second side and the second inner wall.

[0052] The embodiment of the present application does not specifically limit the shape and number of the supporting protrusions, and the supporting protrusions are provided on the first inner wall and the second inner wall of the physical filter chamber 103, the purpose of which is to ensure that there is a gap between the two side surfaces of the physical filter cotton 9 and the inner wall of the physical filter chamber 103. The embodiment of the present application utilizes the supporting protrusions to abut against the side surfaces of the physical filter cotton 9, which is relatively simple to position the physical filter cotton 9 and is also convenient for replacing the physical filter cotton 9.

[0053] Specifically, the supporting protrusions provided on the first inner wall are columnar protrusions 10, and the supporting protrusions provided on the second inner wall are guide bars 13, and the length direction of the guide bars 13 faces the through hole. The embodiment of the present application does not specifically limit the number of columnar protrusions 10 and guide bars 13. Figure 6 As shown, the physical biochemical filter chamber 1 includes a front shell 101 and a rear shell 102, and the front shell 101 and the rear shell 102 are detachably connected. The embodiment of the present application does not limit the specific method of detachable connection. The detachable connection method can facilitate the replacement of the physical filter cotton 9 and the biochemical material in the physical biochemical filter chamber 1; and the edges of the front shell 101 and the rear shell 102 of the physical biochemical filter chamber 1 are provided with sealing ribs 12, and the periphery of the physical filter cotton 9 is respectively interference fit with the sealing ribs 12 and the partition 11, so that the water flow can only be filtered from one side of the physical filter cotton 9 to the other side, thereby improving the effect of filtering impurities. Figure 6 As shown, the space enclosed by the sealing rib 12 and the partition 11 disposed on the first inner wall, that is, the inner wall of the front shell 101, is adapted to the size of the physical filter cotton 9, and a plurality of columnar protrusions 10 are disposed in the space enclosed by the sealing rib 12 and the partition 11. Figure 7 As shown, a plurality of guide strips 13 are arranged at intervals along the length direction of the physical filter cotton 9, the length direction of the guide strips 13 is the width direction of the physical filter cotton 9, and the length direction of the guide strips 13 faces the through hole. Furthermore, a plurality of through holes can be arranged on the partition 11, and the plurality of through holes are arranged at intervals to form a sawtooth shape on the partition 11. By arranging the guide strips 13, on the one hand, the guide strips 13 abut against the second side surface of the physical filter cotton 9, so that a second gap can exist between the second side surface and the second inner wall (the inner wall of the rear shell 102), and on the other hand, the guide strips 13 can guide the water flow so that the water flows smoothly through the through hole into the biochemical filter chamber 104.

[0054] Based on the above embodiments, Figure 8 An exploded view of a filtering device provided in an embodiment of the present application, such as Figure 8 As shown, a water pump 14 and a water storage tank 15 are provided in the water pump 2 of the embodiment of the present application. The water pump 14 is connected to the second water inlet 5 and the water storage tank 15 respectively. The water storage tank 15 is located above the water pump 14, and the second water outlet 6 is provided on the side wall near the top of the water storage tank 15.

[0055] In the embodiment of the present application, a water storage tank 15 is provided above the water pump 14, and a second water outlet 6 is provided on a side wall near the top of the water storage tank 15. When the water level in the water storage tank 15 reaches the position of the second water outlet 6, the water flows out through the second water outlet 6. The purpose of providing the water storage tank 15 is to buffer the water pressure, so that the filtered water can slowly flow into the cylinder 23 to prevent the organisms in the cylinder 23 from being affected.

[0056] The overall water flow power realizes water circulation through the power output of the water pump 14. Driven by the power of the water pump 14, the water first enters the physical filter bin 103 through the first water inlet 3. Since the periphery of the physical filter cotton 9 is respectively sealed with the partition 11 and the sealing rib 12 by interference fit, water can only be filtered from one side of the physical filter cotton 9 to the other side, thereby achieving effective filtration of the water flow and improving the ability to block impurities. The water after physical filtration is guided by the guide strip 13 and enters the biochemical filtration bin 104 through the through hole. Since the biochemical filtration bin 104 is sealed on all sides, the water after biochemical filtration enters the second water inlet 5 through the first water outlet 4. Driven by the power of the water pump 14, the filtered water enters the water storage bin 15 through the water pipe. After the water storage bin 15 is full of water, it flows out through the second water outlet 6.
