Transmissive portions 120 are located in heat-insulation chamber 200, and then avoid infrared transmitting portion 120 directly by thermal-flame and high-temperature flue gas
Scorch, can obviously reduce the temperature in infrared transmitting portion 120, reduce infrared energy of the infrared transmitting portion 120 to external radiation,
So that the infrared energy that infrared temperature sensibility 110 receives is derived from cookware as much as possible, to ensure infrared temperature sensibility 110 to cookware
Thermometric accuracy, finally to ensure thermometric accuracy of the non-contact temperature sensor 1 to cookware.
Further, in the present embodiment, the sensor ontology 10 includes support tube 130 and retainer ring 140, wherein propping up
Stay tube 130 is set along the vertical direction, and retainer ring 140 is fixedly mounted in support tube 130, and infrared temperature sensibility 110 is fixed on fixation
On ring 140, by setting fixing piece, it can be achieved that infrared temperature sensibility 110 is fixed in support tube 130, infrared temperature sensibility 110 is avoided
It is directly contacted with the installation of support tube 130, the support tube 130 for preventing temperature higher carries out hot transmission to infrared temperature sensibility 110, reduces
Support tube 130 interferes the thermometric of infrared temperature sensibility 110.The top of support tube 130 is provided with infrared transmitting portion 120,
In, the top of the support tube 130 is generally set in opening, can the infrared energy that cookware generates be radiated to infrared temperature sensibility
110。

In, guide rod 150 and the lower end of support tube 130 are slidably connected, and support tube 130 can be oppositely oriented bar 150 and slide up and down；Elasticity
Part 160 is placed in support tube 130, and one end of elastic component 160 is abutted with retainer ring 140, and the other end is abutted with guide rod 150.
Retainer ring 140 is located at the top of guide rod 150, and elastic component 160 is between guide rod 150 and retainer ring 140, guide rod 150
It is installed at the burner of gas-cooker, when cookware is positioned on gas-cooker, cookware bottom is abutted with heat shield 20, elastic component 160
Compressed by the effect of cookware gravity so that cookware pulls down heat shield 20 and support tube 130, with ensure every
The good contact of heat cover 20 and cookware, avoids cookware from being jacked up.It is understood that the elastic component 160 can be spring, shrapnel
Deng.
Further, in the present embodiment, the top of support tube 130 is set in open, and infrared transmitting portion 120 includes lid
The transmission element 121 for being installed on 130 top open-mouth of support tube is closed, wherein transmission element 121 has infrared ray preferably transmission to imitate
Fruit, and then can ensure on radiation-curable to the infrared temperature sensibility 110 of infrared energy that cookware generates.It is appreciated that the transmission element 121 1
As for high temp glass, there is preferable heat resistance and saturating infrared light effect.
It should be noted that by the way that the lid of transmission element 121 is set to close the opening on 130 top of support tube, infrared sense can be also avoided
Warm part 110 is directly exposed, and spot is avoided to fall on the surface of infrared temperature sensibility 110, influences its reception to infrared energy, and then
Ensure the normal work of infrared temperature sensibility 110.
In the present embodiment, infrared temperature sensibility 110 is preferably set in distance between transmission element 121, so that infrared
Temperature sensibility 110 can more fully receive the infrared energy transmitted from transmission element 121.
For the ease of the installation of transmission element 121, the top of above-mentioned support tube 130 radially extends outwardly and has installation flange
131, the periphery of installation flange 131 is extended with limiting flange 132 up, and peripheral surface and the limiting flange 132 of transmission element 121 support
It connects, and then realizes that transmission element 121 and the installation of support tube 130 are fixed.
Further, for the ease of heat shield 20 is mounted on support tube 130, the lower end of heat shield 20 corresponds to support tube
130 are equipped with installation via 210, are extended with circular mounting flange 220 upward along the bore edges of installation via 210, annular installation is convex
Edge 220 is arranged the peripheral surface for being fixed on support tube 130.Wherein, circular mounting flange 220 can be between support tube 130 using weldering
It connects fixation or 220 interference of circular mounting flange is set in the peripheral surface of support tube 130.
In the above-described embodiments, the upper surface of the circular mounting flange 220 is preferably abutted with installation flange 131, at this point, every
Heat cover 20 can realize the relative positioning with 130 top of support tube by circular mounting flange 220, so that heat shield 20 is opposite
The mounting height of support tube 130 is relatively fixed, in order to the consistency assembled between heat shield 20 and support tube 130.
When infrared transmitting portion 120 is located in heat-insulation chamber 200, infrared transmitting portion 120 is not higher than the upper end of heat shield 20
Face.In embodiments of the present invention, in order to avoid saturating infrared portion is abutted with cookware, which is less than heat shield 20
Upper surface, i.e., between infrared transmitting portion 120 and cookware have gap.
It is understood that when the top of support tube 130 is provided with transmission element 121, if transmission element 121 connects with cookware
It touches, then be easy to cause 121 surface of transmission element and scratched, transmission element 121 is caused to reduce the transmission effects of infrared ray, and then influence
