[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] Embodiment 1:

[0032] like Figures 1 to 3 As shown, a preferred embodiment 1 of a combustion assembly for a stove of the utility model is shown, and the combustion assembly includes a burner 1, a thermocouple temperature sensor 2, a cover body 3, a mounting seat 4 and an elastic member 5.

[0033] The burner 1 is of prior art, and has a vertically extending channel 10 in the center thereof.

[0034] The above-mentioned mounting seat 4 is arranged in the channel 10 and fixed relative to the channel 10. The mounting seat 4 has a vertically extending mounting cavity 40. The center of the top wall of the mounting cavity 40 has an upper port that passes through from top to bottom. The center of the bottom wall of the mounting cavity 40 is provided with a through hole 42 that passes through from top to bottom. The upper surface of the bottom wall of the mounting cavity 40 is provided with a mounting groove 41 with a notch facing upward. The mounting groove 41 is annular and is located on the periphery of the through hole 42.

[0035] The thermocouple temperature sensor 2 has two thermocouple wires 21 and an insulating protective layer 22. The upper ends of the two thermocouple wires 21 are welded together to form a temperature measuring end 210, and the temperature measuring end 210 is located above the channel 10. The lower ends of the two thermocouple wires 21 extend downward. The insulating protective layer 22 is a glass fiber layer or a glass fiber insulation layer, which is circumferentially wrapped around the outer periphery of the two thermocouple wires 21 as a whole and is located below the temperature measuring end 210. The portion of the thermocouple temperature sensor 2 with the insulating protective layer 22 is inserted into the mounting cavity 40 through the upper port and passes through the through hole 42, so that the thermocouple temperature sensor 2 can move up and down relative to the channel 10.

[0036] The cover body 3 has a top wall 31 and a side wall 32 extending downward from the periphery of the top wall 31. The top wall 31 and the side wall 32 define a cavity with an opening facing downward for the temperature measuring end 210 to be inserted therein. The top wall 31 is a heat-conducting wall with a heat-conducting function and is in contact with the temperature measuring end 210. The side wall 32 is located at the periphery of the insulating protective layer 22 and the lower edge of the side wall 32 is inserted into the cavity of the mounting seat 4. At the same time, the lower edge of the side wall 32 is folded and extended outward to form a flange 33. The size of the flange 33 is larger than the size of the upper port of the mounting cavity 40, so that the cover body 3 can move up and down relative to the mounting seat 4 while preventing the cover body 3 from being separated from the mounting seat 4.

[0037] The elastic member 5 is a vertically arranged spring, which is located in the mounting cavity 40 and is sleeved on the periphery of the insulating protective layer 22, and the lower end of the spring is inserted in the mounting groove 41, and the upper end of the spring acts on the flange 33, so that the cover body 3 and the thermocouple temperature sensor 2 always have a tendency to move upward to the flange 33 abutting against the edge below the upper port of the mounting cavity 40.

[0038] When in use, the cover 3 and the sensor can be raised and lowered according to the shape of the pot bottom so that the cover top wall 31 fits the pot bottom, and the temperature of the pot bottom can be conducted to the temperature measuring end 210 through the cover top wall 31 to achieve accurate temperature measurement.

[0039] Embodiment 2:

[0040] like Figure 4 , 5 As shown, a preferred embodiment 2 of a combustion assembly for a stove of the utility model is shown. This embodiment is basically the same as the embodiment 1, except that in this embodiment, the side wall 32 of the cover body 3 has a first portion 321 extending downward from the periphery of the top wall 31, a second portion 322 extending inwardly from the lower edge of the first portion 321, and a third portion 323 extending downward from the inner periphery of the second portion 322, the lower edge of the third portion 323 is the lower edge of the side wall 32, and the second portion 322 is located below the temperature measuring end 210 and above the insulating protective layer 22, so that the top wall 31 and the side wall 32 of the cover body 3 define a T-shaped cavity with an opening facing downward, and the portion of the cavity corresponding to the temperature measuring end 210 is filled with a heat-conducting medium.

[0041] Meanwhile, in this embodiment, the flange 33 is located above and adjacent to the lower edge of the side wall 32 , and the outer peripheral edge of the flange 33 is adjacent to or in contact with the inner side surface of the installation cavity 40 .

[0042] In this way, the T-shaped cover body 3 in this embodiment can increase the contact area between the top wall of the cover body 3 and the bottom of the pot, which is beneficial to transfer the heat from the bottom of the pot to the temperature measuring end 210 of the sensor, and the T-shaped cover body 3 makes the part of the space corresponding to the temperature measuring end 210 in the cavity larger, which can be filled with heat-conducting medium to improve the accuracy and stability of temperature measurement.
