Fig. 1A is an exploded schematic view of a thermal radiation protection temperature sensor according to one embodiment of the present disclosure. Fig. 1B is a top view of the thermal radiation protection temperature sensor shown in fig. 1A according to one embodiment of the present disclosure. FIG. 1C is a cross-sectional view of a thermal radiation protection temperature sensor taken from A-A' of FIG. 1B according to one embodiment of the present disclosure.

As shown in fig. 1A, 1B and 1C, the thermal radiation prevention temperature sensor according to the embodiment of the present disclosure includes a temperature measuring unit, a support pipe 120 and a mounting slide assembly, and a thermal radiation prevention housing 18. The temperature measuring unit comprises, for example, a metal cap 13 having a temperature measuring surface 11 to be in contact with an object to be measured, a metal cap buckle 12, a metal tube 14 in the metal cap 13, a thermistor 15, a thermistor lead wire 16, and a flat surface 17 of a hollow support tube 120, which is closely attached to the metal cap 13. The mounting slide assembly includes an elastic element, such as a spring 112, and a fixing member including a fixing tube 114, a groove 113 on the fixing tube 114, a snap spring 115 with a groove, a bottom snap spring 116, and a hollow support tube 120, the front and rear of which are indicated by two snap grooves 110 and 111, respectively.

As shown in figure 1A, the thermistor 15 is placed in the metal tube 14, clings to the back of the temperature measuring surface 11 of the metal cap 13, and is fixed by high temperature resistant glue, the end surface 17 of the hollow support tube 120 is buckled in the metal cap 13, the metal cap 13 is fixed by a buckling structure, and the lead 16 of the thermistor is led out from the hollow support tube 120 and is connected with an external circuit.

The thermal radiation prevention cover 18 includes a layer of cover having a height equal to or slightly lower than the metal cap 13, and a connection point of the thermal radiation prevention cover 18 to the support pipe 120 is located near to a position far from the metal cap and has a plurality of apertures, wherein the thermal radiation prevention cover 18 is fixed to an outer wall of the support pipe. For example, the heat radiation prevention cover 18 is slightly lower than or flush with the temperature measuring surface 11 of the metal cap 13, and the connection point of the heat radiation prevention cover 18 and the support tube 120 may be near a position far from the temperature measuring surface 11 and has a plurality of apertures. The heat radiation prevention housing 18 is fixed to the outer wall of the support pipe 120. The spring 112 is fixed between a clamp spring 115 with a notch 118 and a closed fixing tube 114, the lower surface of the fixing tube 114 is clamped in the clamping groove 111 of the hollow supporting tube 120 by a bottom clamp spring 116 for fixing, and the fixing tube 114 is ensured not to slide; the fixed tube 114 is provided with a groove 113 corresponding to the groove 113 through a notch 118 of a snap spring 115, so that the hollow support tube 120 cannot rotate during the up and down movement.

When the thermal radiation prevention temperature sensor is installed on a gas stove through the fixing pipe 114, no object to be measured is on the temperature measuring surface 11 of the sensor, and flowing wind flows inside and outside through the hole 117. After the temperature measuring surface 11 presses the object to be measured, the hollow supporting tube 120 extends downwards, and at least 3mm of distance is reserved between the clamp spring 115 and the lower edge of the heat radiation prevention outer cover 18 (or between the upper edge of the fixed tube 114 and the joint of the supporting tube), so that wind can still pass through the hole 117 to cool the environment of heat radiation and heat conduction brought by heating around, thereby ensuring the accuracy of the temperature measuring temperature of the temperature measuring surface 11, and leading out signals through the thermistor pin 16. Also because of the flow of wind, the installation slip subassembly of this disclosed embodiment is kept away from temperature measurement face 11 among the temperature measurement unit, and its operating temperature who bears also greatly reduced, and the temperature resistant requirement to the spring reduces from this.

According to another embodiment, the mounting slide assembly may be positioned at different distances from the support tube 120, thereby allowing the distance between the temperature measuring unit and the mounting slide assembly in the housing 18 with the thermal radiation protection to be varied, thereby further reducing the effect of high temperatures on the temperature resistance of the mounting slide assembly, and in particular the spring 112.

In the illustration, the diameter of the fixed pipe 114 is significantly smaller than the outer diameter of the metal housing 18, so that the flow of wind is not affected. In this configuration, the hollow support tube 120 is made of metal, and the flat surface 17 thereof is fastened to the metal cap 13, and the lower portion thereof has a plurality of engaging grooves. The installation sliding assembly is arranged in different clamping grooves of the supporting tube 120, so that the distance between the installation sliding assembly and the heat radiation prevention outer cover and the temperature measurement unit is far more than 3mm, the problem that all main parts are concentrated on the head and the feet of the head of the sensor in the prior art is solved, and the heat radiation prevention effect is highlighted.

In the above and following examples, the wall thickness of the fixed pipe is greater than 0.8 mm. Other thicknesses may be selected by those skilled in the art depending on the application.

In fig. 1B, there are a plurality of small holes between the heat radiation shield 18 and the hollow support tube 120, and it is through these small holes that the flowing wind gives off the heat between the inner and outer walls of the heat radiation shield 18. Here, the connection position of the heat radiation prevention cover 18 and the hollow support tube 120 is as far away from the temperature measuring surface as possible. Meanwhile, the outer wall of the heat radiation prevention cover 18 also blocks the influence of heat radiation of a heat source except for a temperature measuring point on the temperature measuring surface.

Fig. 1C is a cross-sectional view of an embodiment of the disclosure, in which a snap spring 115 is snapped into a snap groove 110 of a hollow support tube 120, and a snap spring 116 is snapped into the snap groove 111, and since the bottom of the fixed tube 114 is inwardly closed, the fixed tube 114 is fixed after the snap spring 116 snaps the fixed tube 114. Since the snap spring 115 has the notch 118 and the fixing tube 114 has the groove structure 113, such a structure allows the hollow support tube 120 to be directional when moving up and down.

Fig. 2A is an exploded schematic view of a thermal radiation protection temperature sensor according to another embodiment of the present disclosure. Fig. 2B is a top view of the thermal radiation protection temperature sensor shown in fig. 2A according to another embodiment of the present disclosure. FIG. 2C is a cross-sectional view of a thermal radiation protection temperature sensor taken from B-B' of FIG. 2B, according to another embodiment of the present disclosure. FIG. 2D is a cross-sectional view of a thermal radiation protection temperature sensor taken from B-B' of FIG. 2B under a force according to another embodiment of the present disclosure.

The second embodiment shown in fig. 2A, 2B, 2C and 2D relates to an alternative construction, shown with a two-layer heat radiation proof outer cover 28, the thermometric unit comprising the thermometric surface 21 of the metal cap 23, the thermistor 25, the thermistor lead 26, with a hollow support tube 220 against the plane of the metal cap 23 indicated 27. The mounting sliding assembly comprises an elastic element and a fixing member, wherein the elastic element is for example a spring 212, the fixing member comprises a fixing tube 214 with a closing structure, control caps 225, 219 and 226 are fixing clamps of the fixing tube respectively, screws 221 on the fixing clamps 219 and 226, a trigger switch 222 and clamping grooves 210 and 211 respectively at the tail part of a hollow supporting tube 220.

As shown in fig. 2A, the thermistor 25 is fixed to the temperature measuring surface 21 of the metal cap 23 by high-temperature adhesive. The metal cap 23 is a close fit to the flat surface 27 of the hollow support tube 220, and its thermistor lead 26 is led out through the hollow support tube 220.

The thermal radiation protection outer cover 28 is a two-layer outer cover, the height of the first layer of outer cover is flush with or slightly lower than that of the metal cap of the temperature measuring unit, the connection point of the thermal radiation protection outer cover and the supporting pipe is close to the position far away from the metal cap, and the thermal radiation protection outer cover is provided with a plurality of holes, wherein the thermal radiation protection outer cover is fixed on the outer wall of the supporting pipe. The second layer of the thermal radiation shield 28 is connected to and disposed outside the first layer of the housing. A plurality of holes are formed near the joint of the first layer of outer cover and the second layer of outer cover, and the height between the first layer of outer cover and the second layer of outer cover is flush with or slightly lower than the metal cap of the temperature measuring unit. Thus, the heat radiation preventing cover 28 has two layers of heat radiation preventing effect, and is fixed on the outer wall of the hollow support tube 220, the connecting position of the heat radiation preventing cover 28 and the outer wall of the hollow support tube 220 is far away from the temperature measuring surface 21 as far as possible, and the height of the heat radiation preventing cover 28 is lower than or parallel to the temperature measuring plane 21.

The spring 212 is encased in a stationary tube 214 and passes through a hollow support tube 220, bounded on one side by a necked-in position 224 of the stationary tube 214 and on the other side by a circlip 215. The clamp spring 215 is clamped on the clamping groove 210 of the hollow support tube 220 and placed in the control cap 225, and the clamp 22 of the control cap 225 in the hollow support tube 220 is clamped and fixed with the clamping groove 218 of the fixing tube 214.

The fixing clips 219 and 226 are mounted on the bottom of the gas cooker through screws 221, and the tact switch 222 is fixed on the fixing clip 226 and perpendicular to the hollow support tube 220.

As shown in fig. 2B, the thermal radiation protection cover 28 has apertures 217 and 223, respectively, and when the sensor is in operation, the flowing wind lowers the temperature of the 217 and 223 aperture regions, respectively, to form dual thermal radiation protection when the sensor passes through the 217 and 223 apertures, respectively, due to the flowing wind.

As shown in fig. 2C, the sensor of the present embodiment is in a stationary state after being installed, and fig. 2D is a structure formed after the weight of the object to be measured is pressed, wherein the distance between the control cap 225 and the aperture 223 is at least maintained to be more than 3mm, after the whole sensor is fixed on the gas cooker through the fixing clips 219 and 226, the hollow support tube 220 is extended and contracted up and down by the weight of the object to be measured, and the silica gel sleeve is sleeved on the tail portion of the hollow support tube 220 to mainly isolate the heat transferred from the hollow support tube 220, thereby triggering the operation of the touch switch 222. By the operation of the touch switch 222, whether the object to be detected is pressed on the sensor or not can be known, so that the pot detection function is realized. Here, the temperature around the tact switch 222 is not too high by the flow of the wind, and the tact switch 222 is prevented from being damaged in the high temperature process of the thermal radiation prevention temperature sensing test, thereby reducing the performance requirement of the tact switch 222.

As shown in fig. 2D, the sensor of this embodiment is in an actual working state, wherein an object to be measured is pressed on the temperature measuring surface 21, the spring 212 moves downward under the influence of gravity, and since the fixing tube 214 is fixed on the lower portion of the gas cooker through the fixing clips 219 and 226 and the screw 221, in order to ensure the heat radiation protection effect, the distance between the control cap 225 and the inner hole 223 of the heat radiation protection housing must be greater than 3 mm. The installation sliding components are arranged in different clamping grooves 210 and 211 of the supporting pipe 220, so that the installation sliding components are far away from the heat radiation prevention outer cover 28 and the temperature measuring unit by more than 3 mm. From the practical effect, the longer the actual distance exceeding 3mm, the lower the temperature resistance requirement of the spring 212 and the touch switch 222 for installing the sliding assembly through the flowing of wind, and the best effect of preventing heat radiation is achieved.

The above-described embodiment solves the problem in the prior art that the components of the sensor are concentrated on the head and feet of the head, and highlights the effect of preventing heat radiation.

As can be seen from the change in motion of FIGS. 2C to 2D, the inner diameter of control cap 225 and the gap between the inner diameter of the lower constriction of stationary tube 23 and the outer diameter of hollow support tube 220 determine the range of wobble of the present sensor. The smaller the inner diameter of the control cap 225 and the inner diameter of the lower portion of the fixed tube 23, the smaller the range in which the hollow support tube 220 can rock. For example, the inner diameter of the control cap and the inner diameter of the constriction of the fixation tube are as close as possible to the outer diameter of the support tube.

In summary, aiming at the problems in the prior art, the temperature sensor of the embodiment of the present disclosure can achieve at least one of the following technical effects: first, the sensor components of the prior art are concentrated on the head of the sensor, so that the dry-burning prevention temperature sensor of the gas stove is heavy and light in weight and easy to damage in practical use. Aiming at the situation, the temperature measuring part and the sliding part of the product are separated, the temperature measuring part and the sliding part are not concentrated on the head, and the head only keeps the heat radiation prevention outer cover and the temperature measuring part. Secondly, the sliding part is arranged at the other end of the supporting tube, so that the requirement of the spring on high temperature is not strict, and the reliability of the spring can be realized. Third, the thermal radiation protection in the disclosed embodiment is divided into one or two layers, and is never connected to the metal cap for temperature measurement. When wind gushes upwards from the lower part of the gas cooker, the flow of the wind cools the heat radiation prevention inner wall and the outer wall of the support frame, and the installation sliding assembly is also cooled. Fourth, the fixing tube in the disclosed embodiment is independent, and its thickness has any influence on the whole product, so that a strong and firm material can be selected. Fifth, the embodiment of the present disclosure uses a hollow supporting tube to support the belt having the thermal radiation protection cover, the temperature measuring portion, and the sliding component for fixing and extending, so that the method of using the hollow supporting tube to trigger the touch switch is simple and reliable, and has the same pot detection function. The temperature sensor of the embodiment of the disclosure can not shake in the actual work by controlling the inner diameter of the closing-up of the fixed tube in the fixed component and the inner diameter of the control cap, so that the purposes of safe use and accurate temperature measurement are achieved.
