[0025] The controller 34 is electrically connected to the liquid level sensor 7, the heater 9, the electric valve 13, the air inflation pump 27, and the ammonia concentration sensor 28 respectively.
[0026] During specific use, in the initial state, the cover plate 24 is located on the upper wall of the experimental cage 2, the bolt 25 is screwed into the interior of the experimental cage 2, the cover plate 24 is fixedly placed on the upper wall of the experimental cage 2. Rotate the bolt 25, the bolt 25 is screwed out from the interior of the experimental cage 2, and the cover plate 24 with the one-way intake valve 26 is removed from the upper wall of the experimental cage 2. The experimental mouse is placed on the upper wall of the grid plate 21 inside the experimental cage 2, the cover plate 24 is covered onto the upper wall of the experimental cage 2, and the bolt 25 is screwed into the interior of the experimental cage 2, and the cover plate 24 is fixed again; Rotate the conical cylinder 3, the conical cylinder 3 is screwed out from the inner wall of the experimental cage 2, a new sponge layer 22 is placed inside the conical cylinder 3, and then the conical cylinder 3 is screwed into the bottom inner wall of the experimental cage 2. The feces generated by the experimental mouse moving inside the experimental cage 2 pass through the grid plate 21 and fall onto the upper wall of the sponge layer 22; The water injection pipe 12 is communicated with an external water pipe. The external water pipe injects water into the constant temperature cylinder 8 through the water injection pipe 12. The controller 34 controls the liquid level sensor 7 to start. The liquid level sensor 7 detects the water level inside the constant temperature cylinder 8 through the position measuring end. When the feeding water inside the constant temperature cylinder 8 reaches the position measuring end of the liquid level sensor 7, the water injection into the constant temperature cylinder 8 is stopped. When the liquid level inside the constant temperature cylinder 8 drops, the external water replenishes water to the constant temperature cylinder 8 through the one-way water inlet pipe 6. The controller 34 controls the heater 9 to start. The heater 9 heats the feeding water inside the constant temperature cylinder 8 through the heating end to keep the feeding water inside the constant temperature cylinder 8 in a constant temperature state. The electric valve 13 is in a blocked state in the initial state. The controller 34 controls the electric valve 13 to open regularly, the water injection pipe 12 is conducted, and the constant temperature water inside the constant temperature cylinder 8 flows into the automatic water dispenser 11 to provide water for the experimental mouse. The experimental mouse obtains water through the automatic water dispenser 11; The controller 34 controls the ammonia concentration sensor 28 to start, and the ammonia concentration sensor 28 monitors the ammonia concentration inside the experimental cage 2 in real time to prevent the ammonia concentration inside the experimental cage 2 from exceeding the standard and affecting the survival of the experimental mice. The feeding water inside the constant temperature cylinder 8 will generate water vapor when maintaining a constant temperature state. The water vapor flows into the incubator 16 through the steam pipe 15. The pressure relief threshold of the pressure relief valve 17 is pre-set. When the steam pressure value entering the incubator 16 reaches the pressure relief threshold of the pressure relief valve 17, the water vapor inside the incubator 16 is quickly ejected. The water vapor flows into the negative pressure pipe 18 at a high speed, and a negative pressure is generated inside the negative pressure pipe 18. The negative pressure pipe 18 extracts the air inside the experimental cage 2 through the one-way air intake valve 19, and the air pressure inside the experimental cage 2 is reduced. The outside air enters the experimental cage 2 through the one-way air intake valve 26, and fresh air is added to the experimental cage 2, reducing the concentration of ammonia inside the experimental cage 2. When the droplets in the water vapor come into contact with the ammonia, the ammonia will quickly dissolve in the water to form ammonia water. The one-way air intake valve 26 sprays the formed ammonia water into the sponge layer 22 for storage. When there is a lot of feces on the upper wall of the sponge layer 22, the ammonia concentration sensor 28 detects that the ammonia concentration inside the experimental cage 2 exceeds the standard. At this time, the controller 34 controls the air pump 27 to start, and the air pump 27 draws air from the outside through the suction end. The outside air enters the experimental cage 2 through the exhaust end of the air pump 27. The air containing excessive ammonia in the experimental cage 2 passes through the sponge layer 22 and flows into the liquid collecting box 31 through the one-way discharge valve 35 and the hose 30. The excess air is discharged through the filter valve 32 after being filtered by the activated carbon filter layer 33. Then, the conical cylinder 3 is rotated, and the conical cylinder 3 is rotated out from the bottom wall of the experimental cage 2, and the sponge layer 22 inside the conical cylinder 3 is replaced. The conical cylinder 3 with the replaced sponge layer 22 is rotated into the bottom wall of the experimental cage 2 again. By utilizing the power of the water vapor gathered inside the constant temperature cylinder 8, fresh air can be regularly replenished into the experimental cage 2, and the water vapor can provide moisture to the sponge layer 22, dilute the concentration of the fecal liquid inside the sponge layer 22, and reduce the probability of excessive ammonia concentration inside the experimental cage 2. Under the flushing of water vapor, the liquid produced by the feces can be brought into the liquid collection box 31 for storage; just repeat the above operation when using it next time.
