The humidifier 11 is used for adjusting the humidity in the feeding chamber 2 and adjusting the humidity in the feeding chamber 2 to be within a preset humidity range. Wherein, the preset humidity interval can be 40-70%. Taking the preset temperature interval of 40% -70% as an example, when the humidity value in the feeding chamber 2 collected by the temperature and humidity sensor is lower than 40%, the controller 8 starts the humidifier 11 and the air conditioner 9, humidifies the air flow generated by the air conditioner 9 through the humidifier 11, and accordingly humidifies the feeding chamber 2, and when the humidity in the feeding chamber 2 is greater than or equal to 40%, the controller 8 closes the humidifier 11 and the air conditioner 9.

The humidifier 11 may be a stainless steel wet film humidifier, or may be other types of humidifiers, which are not specifically limited in the present invention. When the humidifier 11 is a stainless steel wet film humidifier, in order to save the space of the small-sized mammal raising device, the humidifier 11 can be connected with the drinking water tank 5, and the water source of the stainless steel wet film can adopt the water in the drinking water tank 5. When the water source of the stainless steel wet film adopts the water in the drinking water tank 5, the water in the drinking water tank 5 is not added with the test medicine.

In one embodiment, the small mammal breeding device may further include a first microbial filter 13 and a second microbial filter 14.

For example, when the electric device is the sensor 6, the status data is the sensing data in the feeding chamber 2 collected by the sensor 6, and the sensing data is transmitted to the controller 8. When the electricity-using device is a pressurizing device, the state data is a pressure value in the drinking water tank 5 acquired by the pressurizing device, and the pressure value is sent to the controller 8.

The controller 8 generates information to be displayed based on the status data and transmits the information to be displayed to the control panel 7 or transmits the information to be displayed to the ground controller.

The control panel 7 displays the received information to be displayed.

Further, the control panel 7 receives a control command input by a user for the electric device, and transmits the control command to the controller 8.
