[0037] See also Figure 1-4 The utility model provides a fully automatic intelligent experimental animal asphyxiation cabinet, which includes:

[0038] An asphyxiation cabinet body 1, wherein at least one asphyxiation chamber 2 is disposed in the asphyxiation cabinet body 1, wherein a first air inlet 3 and a first air outlet 4 are disposed on the asphyxiation chamber 2, and wherein a lighting device 5 and a sterilization device 6 are disposed in the asphyxiation chamber 2;

[0039] A blower 7, wherein a second air inlet of the blower 7 is connected to an asphyxiating gas connector 8 via a first pipe, the asphyxiating gas connector 8 is fixedly connected to an outer surface of the asphyxiating cabinet body 1, and a first air outlet of the blower 7 is connected to a first air inlet 3 via a second pipe;

[0040] An exhaust fan 9, wherein a third air inlet of the exhaust fan 9 is connected to the first air outlet 4 via a third pipe, and a second air outlet of the exhaust fan 9 is connected to an air outlet 10 on the asphyxiation cabinet body 1 via a fourth pipe;

[0041] A control box 11 is disposed in the asphyxiation cabinet body 1 , and the air supply fan 7 and the exhaust fan 9 are electrically connected to the control box 11 .

[0042] There are four asphyxiation chambers 2, which are arranged in sequence from top to bottom. The first air inlet 3 on each of the asphyxiation chambers 2 is connected through a first air duct 12, and the first air duct 12 is connected to the second pipe. The first exhaust port 4 on each of the asphyxiation chambers 2 is connected through a second air duct, and the second air duct 13 is connected to the third pipe.

[0043] The four asphyxiation chambers operate independently, and a solenoid valve is provided at the first air inlet and the first exhaust port of each asphyxiation chamber, and the solenoid valve is connected to a control box, and the control box controls the opening of the solenoid valve. The specifications of the four asphyxiation chambers can be the same or different, so that multiple cages can be placed at the same time for mass euthanasia, which improves efficiency.

[0044] The two sides of the asphyxiation cabinet body 1 are respectively provided with installation cavities 14, and the first air duct 12 and the second air duct are arranged in the corresponding installation cavities 14. In this way, the first air duct and the second air duct can be prevented from leaking out, and a hidden installation can be achieved, which can protect the first air duct and the second air duct.

[0045] The top of the asphyxiation chamber 2 is provided with a third air duct 15, the third air duct 15 is connected to the first air inlet 3, and a plurality of exhaust holes 16 are provided on the third air duct 15. The asphyxiation gas carbon dioxide can be filled into the asphyxiation chamber more quickly, thereby improving the filling efficiency of the asphyxiation gas.

[0049] Working principle: The asphyxiation cabinet of the present invention is mainly used for euthanasia of small experimental animals such as mice, guinea pigs, etc., and can be placed in multiple cages for large-scale euthanasia. The working principle of the asphyxiation cabinet is to automatically inject carbon dioxide gas into the cabin, and then suffocate it after reaching the required concentration for asphyxiation until the animal suffocates to death. After the operation is completed, the carbon dioxide in the cabin is discharged through a pipeline to prevent overflow, which can maximize the safety and health of the operator. Specifically, the asphyxiation gas connector 8 is connected to the carbon dioxide cylinder, and the cage containing the animal is placed in the asphyxiation chamber 2. First, the exhaust fan is started to extract the air in the asphyxiation chamber, and then the exhaust fan is turned off and the air supply fan is turned on at the same time to send the asphyxiation gas carbon dioxide into the asphyxiation chamber. In this way, the asphyxiation chamber can be evenly filled with carbon dioxide, and the carbon dioxide will not be located at the bottom of the asphyxiation chamber due to the air in the asphyxiation chamber. Finally, the exhaust fan is started to extract the carbon dioxide.
