At the bottom of the hot air delivery pipe 40, there is a hot air hood 50. The air inlet end of the hot air hood 50 is connected to the hot air delivery pipe 40 through a telescopic corrugated pipe 51. By setting the air inlet box 20, external air can be introduced into the device. The servo fan 22 inside the air inlet box 20 can provide power for the flow of air. The adjustment knob can control the rotation speed of the servo fan 22, thereby adjusting the amount of air intake.

[0036] Working principle of the temperature - controllable pigsty ventilation adjustment device:

[0037] First, the operator starts the servo - blower 22 in the air inlet box 20 through the adjustment knob on the control panel 30 for controlling the rotation speed of the servo - blower 22. At this time, external air is sucked into the air inlet box 20.

[0038] Next, the air enters the heating box 10 from the air outlet end of the air inlet box 20. According to the required temperature in the pigsty, by turning on the switches of the corresponding number of electric heating grids 11 respectively through the control panel 30 for each group of electric heating grids 11, the air is heated.

[0039] Then, the heated air is transported through the hot air delivery pipe 40.
