A return pipe 10 is threadedly fixed to the left end of the multi-stage bactericidal air stone filter box 9. This design solves the problem that the existing vacuum cleaner has limited functionality and shape flexibility in the use of ordinary indoor and laboratory breeding scenarios, which reduces its scope of application.
[0024] As the first embodiment of this utility model: a motor 23 is fixedly connected inside the algae-cleaning device 8, and a cleaning disc 22 is fixedly connected to the output end of the motor 23. The motor 23 installed in the algae-cleaning device 8 can drive the cleaning disc 22 to remove the algae in the aquarium, and then the algae and sludge are sucked away through the suction head 1, reducing the impact of sludge in the aquarium on the fish. Hinges 2 are provided on the circumferential surfaces of the water pipe 4, connecting pipe 5, and sliding pipe 11. The front end of the multi-stage bacteria-adding air stone filter box 9 is rotatably connected to a sealing door 14 through a hinge shaft. The hinges 2 installed on the surfaces of the water pipe 4, connecting pipe 5, and sliding pipe 11 are used to store the water pipe 4, connecting pipe 5, and sliding pipe 11 in the box for easy carrying of the equipment. The sealing door 14 installed at the front end of the multi-stage bacteria-adding air stone filter box 9 allows the user to easily remove the filtered uneaten food, feces, and algae, effectively purifying the water source in the aquarium. The water pipe 4 and the algae removal device 8 are threaded together. The cleaning disc 22 is made of rubber. To remove algae, first unscrew the suction head 1 and then fix it to the algae removal device 8. The motor 23 drives the cleaning disc 22 to remove the algae in the tank. Simultaneously, the user can move the water pipe 4 to control the movement direction of the algae removal device 8 for convenient subsequent operation. A protective pad 21 is fixedly connected to the lower end of the suction head 1. The algae removal device 8 has a waterproof layer. The protective pad 21 at the bottom of the suction head 1 protects the bottom of the suction head 1, preventing collisions between the tank bottom and the suction head 1.

The uneaten food and feces at the bottom of the tank will enter the nitrifying bacteria storage box 6 through the connecting pipe 5 and the sliding pipe 11 under the suction of the silent water pump 3. The filter box 20 can effectively filter the uneaten food and feces. The nitrifying bacteria in the filter box 20 can purify the water quality. After the nitrifying bacteria storage box 6 is full, it will enter the multi-stage bactericidal air stone filter box 9 through the hose 7. The internal filter plate 17 can filter the water again. Finally, it will be discharged back into the water tank through the return pipe 10. After completing the water filtration and circulation, when the algae in the tank needs to be cleaned, the suction head 1 can be unscrewed from the water pipe 4 and connected to the algae removal device 8. After placing the algae removal device 8 on the algae, the cleaning disc 22 will be rotated by the motor 23 to knock off the algae. The user can adjust the position of the water pipe 4 to control the direction of the algae removal device 8. After removing the algae, the suction head 1 can be connected again to suck it out. When the equipment needs to be carried, the multiple components need to be unscrewed. The connecting pipe 5 can be slid into the sliding pipe 11 and then folded and stored through the hinge head 2. Then, the sealing door 14 and the nitrifying bacteria storage box 6 can be opened to take out the sliding box 16 and the filter box 20 for cleaning.
