Heat sensor with driving function

Abstract

Provided is a heat sensor with a driving function. The heat sensor is provided with a sleeve, an air cylinder for driving and a U-shaped tube. One end of the sleeve is provided with a sleeve cap, and the other end of the sleeve is open; one end of the U-shaped tube is inserted into the sleeve from the open end of the sleeve, and the other end of the U-shaped tube is connected with the air cylinder; sleeve inner threads running through the sleeve are formed in the center of the sleeve cap, and the sleeve cap is connected with a heat collection needle through the sleeve inner threads, wherein the heat collection needle is used for absorbing heat sources. The air cylinder is provided with a two-hole screw arranged at one end of a longitudinally through air cylinder body and used for being inserted into the two open ends of the U-shaped tube, a rubber sealing cap arranged in the air cylinder body and combined with the two-hole screw tightly and a T-shaped tubular piston arranged at the other end of the air cylinder body, and the T-shaped tubular piston can stretch out to be used for driving an external part to move when the rubber sealing cap is heated to expand. Thermal cycle power can be generated after the inner portion of the heat sensor is under the high temperature, power is conveyed to a control switch repeatedly and continuously, and the heat sensor cannot be damaged because of flame ablation, and is reliable and durable.

Description

technical field [0001] The invention relates to a thermal sensor. In particular, it relates to a thermal sensor with drive function. Background technique [0002] In the prior art both at home and abroad, the sensors used for the gas leakage prevention device of the burning appliance all adopt thermocouples as control switches. The thermocouple is made of two kinds of metals. Due to the different heat conduction conditions and different molecular chain structures, a potential difference will be generated when the flame is heated. The current generated by the potential difference is used as the power source of the control switch, but the thermocouple is not resistant to flame ablation. Once the metal chain structure is destroyed after ablation, the function of the control switch will be lost, and there will be no obvious response, so there are still potential hidden dangers. In order to avoid this potential hidden danger, it is urgent to choose other solutions to avoid the ...
