Technical Field

[0001] The utility model relates to the technical field of temperature sensors, and more specifically to a floor heating NTC thermistor temperature sensor. Background Art

[0002] Floor heating NTC thermistor temperature sensors are important components for measuring temperature in floor heating systems. NTC thermistors are negative temperature coefficient thermistors, whose core components are made of temperature-sensitive materials, typically semiconductor materials such as manganese, cobalt, nickel, and copper oxides. As the temperature rises, the resistance of the thermistor decreases rapidly; as the temperature decreases, the resistance increases. Floor heating NTC thermistor temperature sensors utilize this characteristic, measuring changes in resistance to reflect changes in floor temperature.

[0003] For example, the NTC thermistor for temperature sensors with prior art publication number CN206420579U has the advantages of simple structure, easy use, good sealing, high insulation performance, strong weather resistance, high reliability, and low cost. It has fast reaction time, rapid response, good stability, and can well protect equipment. It can be widely used in fire temperature sensors and water heater temperature sensor industries.

[0004] However, the above-mentioned prior art still has the following problems when in use: the existing temperature sensor is directly installed under the floor. When the user steps on the floor, the floor presses down on the temperature sensor for a long time, causing damage to the temperature sensor. Based on this, the utility model provides a floor heating NTC thermistor temperature sensor. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Refer to the instruction manual Figure 1-5The present invention provides a floor heating NTC thermistor temperature sensor, including a temperature sensor body 1, the temperature sensor body 1 including a copper shell 101 and an NTC thermistor body 102, the NTC thermistor body 102 is fixed inside the copper shell 101, the outer wall of the copper shell 101 is fixedly sleeved with a shell 103, the space between the NTC thermistor body 102 and the copper shell 101 is filled with epoxy resin 3, the rear end of the NTC thermistor body 102 is connected to two lead wires 4, the rear ends of the two lead wires 4 both pass through the rear of the shell 103 for connecting to a temperature control system;

[0026] The outer wall of the shell 103 is provided with a reinforcement component 2, and the reinforcement component 2 includes a reinforcement block 201. A mounting hole 202 is provided at the front end of the reinforcement block 201, and the shell 103 passes through the mounting hole 202. A rubber pad 203 is fixed to the top of the reinforcement block 201, and a pressure plate 204 is fixed to the top of the rubber pad 203. A plurality of compression springs 205 are fixed on both sides of the bottom end of the pressure plate 204. A groove 206 is provided on both sides of the top of the reinforcement block 201, and a compression spring 205 is fixed between the bottom of the pressure plate 204 and the inner wall of the bottom of the groove 206.

[0027] Furthermore, the plurality of compression springs 205 inside the two grooves 206 are distributed in a linear array, and the compression springs 205 play a buffering role at the bottom of the pressure plate 204, thereby improving the buffering performance.

[0028] During use, the staff first fixes the shell 103 in the mounting hole 202 of the reinforcement block 201, and uses the expansion bolt 7 to firmly fix the shell 103 and the reinforcement block 201 together, and then fixes the reinforcement block 201 to the ground. The temperature sensor body 1 is used to monitor the temperature of the floor in real time to prevent the floor heating temperature from being too high or too low and affecting use. A pressure plate 204 is set above the reinforcement block 201. When the floor presses the pressure plate 204, the pressure plate 204 presses down the rubber pad 203 and the compression spring 205. The elastic force of the compression spring 205 and the rubber pad 203 can play a buffering role, thereby playing a buffering support role under the floor, thereby improving the pressure resistance and service life of the temperature sensor body 1.

[0031] The reinforcement block 201 and the shell 103 are detachably fixed together by multiple expansion bolts 7. Circular grooves 8 are provided on the bottom and both sides of the reinforcement block 201.
