[0030] The working principle of the above embodiment is:

[0031] (1) When adjusting the height of the support plate 305, the motor 302 is first started. The output shaft of the motor 302 rotates to drive one of the threaded rods 303 to rotate, and then drives the other threaded rod 303 to rotate through the belt transmission. The rotation of the two threaded rods 303 causes the movable sleeve 304 threadedly connected to the surface thereof to move upward or downward.

The movement of the support plate 305 can extend or shorten the telescopic rod 307, and the other end of the support plate 305 can be limited, so that the height of the support plate 305 can be adjusted, so that the space of the culture chamber 2 is changed, and it is convenient to put incubators of different sizes.

[0032] (2) The temperature in the culture chamber 2 can be sensed in real time by a set temperature sensor. If the temperature is lower than the set value, the temperature sensor transmits a signal to the controller. The controller controls the switch of the fan 401 and the switch of the heating box 402, starts the fan 401 and turns on the heating box 402. The air inlet end of the fan 401 can draw in the outside air through the air inlet pipe and filter the drawn air. The drawn air enters the air outlet pipe and the inner cavity of the heating box 402 through the air inlet pipe. The air entering the inner cavity of the heating box 402 can be heated by the electric heating wire 403 to become hot air, and then enters the inner cavity of the hollow tube 404 through the air guide pipe, and finally is ejected through the nozzle 405. The ejected hot air can enter the culture chamber 2 through the ventilation net 406, which can increase the temperature in the culture chamber 2.
