The pressing plug 22 and the pressing rod 221 are integrally formed and can reciprocate along a preset direction S under the drive of the motor 12, so that the pressing plug 22 closes or opens the communication port 41; by adjusting the flow rate through the pipe section 40 by changing the opening degree of the communication port 41, the temperature of the space can be adjusted, and the temperature can be restored to the set value. Specifically, when the temperature of the space is lower than the set temperature, the pressing plug 22 moves along the preset direction S, the pressing plug 22 opens the communication port 41 to allow the heat medium to pass through, and the temperature of the space is regulated; when the temperature of the space reaches the set temperature, the pressing plug 22 moves along the preset direction S, and the pressing plug 22 closes the communication port 41, so that the temperature of the space can be dynamically balanced near the set temperature.

Further, the stopper head 222 is funnel-shaped, and gradually decreases in diameter of the stopper 22 toward the communication port 41 in the preset direction S. As the plunger head 222 moves in the preset direction S toward the communication port 41, the flow rate of the communication port 41 gradually decreases; as the plunger head 222 moves in the preset direction S in a direction away from the communication port 41, the flow rate of the communication port 41 gradually increases, and the flow rate of the communication port 41 is adjusted.
