The basic principle of the quick response temperature controller is as follows: the temperature sensing piece 300 detects the actual temperature outside the temperature controller, the temperature sensing cover 100 is used for providing protection for the temperature sensing piece 300, when the temperature sensing piece 300 detects that the external actual temperature reaches (or exceeds) the jump temperature, the temperature sensing piece 300 jumps, and the temperature sensing piece 300 downwards presses and cooperates with the action rod 400 when the jump temperature is reached, so that the pressed action rod 400 can trigger other components in the temperature control main body.

On the basis of the above structure, in order to improve the temperature sensing sensitivity and quickly respond to the actual temperature change outside, a pressing piece 500 is disposed between the bottom wall of the temperature sensing piece 300 and the bottom wall of the storage cavity 200, the pressing piece 500 abuts against the temperature sensing piece 300 and is used for pressing the temperature sensing piece 300 towards the temperature sensing cover 100, so that the temperature sensing piece 300 is closer to the temperature sensing cover 100 and is more easily affected by the change of the outside temperature. Specifically, when the temperature-sensing piece 300 detects that the actual temperature of the external connection does not reach the jump temperature, the temperature-sensing piece 300 maintains the original state and does not jump, the top pressing piece 500 and the temperature-sensing piece 300 are both convex upwards, the curvature radius of the top pressing piece 500 is larger, and the top pressing piece 500 presses the temperature-sensing piece 300 which does not reach the jump temperature to be in contact with the lower surface of the temperature-sensing cover 100; when the temperature sensing piece 300 detects that the actual temperature of the external connection reaches (or exceeds) the jump temperature, the temperature sensing piece 300 jumps, and the temperature sensing piece 300 jumps and then protrudes downwards to press the action rod 400, so that the pressing piece 500 is pressed to protrude downwards.

In this embodiment, the top pressing plate 500 is made of a temperature sensing metal plate, and the reset temperature of the top pressing plate 500 is lower than the reset temperature of the temperature sensing plate 300, more specifically, the reset temperature of the top pressing plate 500 is less than or equal to 0 ℃, so that the reset temperature of the top pressing plate 500 is not in the range of the jump temperature and the reset temperature of the temperature sensor, and the top pressing plate 500 is not affected by the temperature change in the working temperature range of the temperature sensing plate 300.

In some embodiments, the pressing plate 500 has a rod hole 501, and the actuating rod 400 passes through the rod hole 501 to abut against the lower surface of the temperature sensing piece 300, so that the temperature sensing piece 300 is conveniently matched with the actuating rod 400.
