The first screw 5 passes through the first through hole 41 and is connected to the first fixing part 21.

[0035] Specifically, the liquid tray 4 has a liquid holding groove, and the first through holes 41 are spaced apart along the circumference of the liquid holding groove.

[0036] In this embodiment, the lower end of the liquid-holding tray 4 is connected to the upper end of the support frame 2 so that the liquid-holding tray 4 is fitted onto the outside of the burner head 1, and the liquid-holding tray 4 can also cover the support frame 2 below it. In addition, a plurality of first fixing parts 21 are arranged at intervals along the circumference of the support frame 2, and a plurality of first through holes 41 are correspondingly opened on the liquid-holding groove of the liquid-holding tray 4. The first screw 5 passes through the first through hole 41 and connects to the first fixing part 21, so that the liquid-holding tray 4 can be fixedly installed on the support frame 2 by the first screw 5. More preferably, since there is an opening on the panel of the stove body, the burner head 1 is set at the opening position of the stove body, and then the upper edge of the liquid-holding tray 4 is fitted onto the outer edge of the opening of the stove body, and the lower end wall of the liquid-holding tray 4 is connected to the support frame 2, so that the displacement of the liquid-holding tray 4 can be limited, thereby effectively improving the stability of the installation of the liquid-holding tray 4.

[0037] Preferably, a first and second air passage 6 is provided between the inner side of the upper end of the support frame 2 and the outer side wall of the burner head 1, and a first vent is provided on the bottom wall of the stove body to communicate with the lower end of the first and second air passage 6. A second and second air passage 7 is provided between the liquid tray 4 and the burner head 1, and the second and second air passage 7 is connected to the upper end of the first and second air passage 6.

[0038] Furthermore, it also includes a second screw 8. Multiple second fixing parts 22 are provided at intervals along the circumference on the support frame 2. A second through hole 32 is provided on the connecting bracket 3. The second screw 8 passes through the second through hole 32 and is connected to the second fixing part 22.

[0039] Preferably, an upper flange 23 is provided at the upper end of the support frame 2 along the circumference of the burner head 1, and a groove 24 is provided at each second fixing part 22 of the upper flange 23. After the connecting bracket 3 is inserted into the groove 24 at the end away from the burner head 1, the connecting bracket 3 is connected to the support frame 2 by the second screw 8.

[0040] Specifically, it also includes a third screw. The stove has a stove body, on which a third fixing part is correspondingly provided. A lower flange 25 is protruding at the lower end of the support frame 2. Multiple third through holes 26 are spaced apart along the circumferential direction on the lower flange 25. The third screw passes through the third through hole 26 and connects to the third fixing part.

[0041] In this embodiment, an upper flange 23 is provided at the upper end of the support frame 2 along the circumference of the burner head 1, and a plurality of grooves 24 are recessed at intervals along the circumference of the upper flange 23. A second fixing part 22 is provided at each groove 24. At the same time, a second through hole 32 is provided on the connecting bracket 3. After one end of the connecting bracket 3 is embedded in the groove 24, the displacement of the connecting bracket 3 is effectively limited. The second screw 8 passes through the second through hole 32 and is connected to the second fixing part 22. Then, the end of the connecting bracket 3 away from the support frame 2 is connected to the outer wall of the burner head 1, thereby fixing the burner and the support frame 2 together through the connecting bracket 3. In addition, multiple first fixing parts 21 are spaced apart along the circumferential direction on the upper flange 23, and the first fixing parts 21 and the second fixing parts 22 are staggered. Multiple first through holes 41 are correspondingly opened on the liquid holding tank of the liquid holding tray 4. The first screw 5 passes through the first through hole 41 and connects to the first fixing part 21, so that the liquid holding tray 4 can be fixedly installed on the upper flange 23 of the support frame 2 by the first screw 5, thereby hiding the screw fixing the burner under the liquid holding tray 4, so as to effectively improve the appearance of the product.

[0042] More preferably, a vent is provided on the bottom wall of the stove body, and a first secondary air passage 6 is defined between the inner end of the flange 23 on the support plate and the burner head 1. Simultaneously, a second secondary air passage 7 is defined between the liquid tray 4 and the burner head 1. The lower end of the first secondary air passage 6 is connected to the second vent, and its upper end is connected to the upper end of the second secondary air passage 7. Low-temperature cold air flows sequentially through the vent, the first secondary air passage 6, and the second secondary air passage 7 before flowing upwards, thus carrying away some of the heat from the outer periphery of the burner. More preferably, a third secondary air passage is provided vertically in the middle of the burner head 1. The first secondary air passage 6 is connected to an opening on the bottom wall of the stove body. Low-temperature cold air flows upwards through the third secondary air passage, also carrying away some of the heat from the interior space of the burner head 1.

[0043] Preferably, it also includes a flow-guiding heat insulation plate 9, which is disposed in the premixing chamber 11, and has a plurality of vent holes 91 for the mixed gas to pass through.

[0044] Specifically, it also includes a fourth screw 92, a fourth fixing part 13 is provided at the upper end of the premixing chamber 11, a fourth through hole 93 is provided on the flow guiding heat insulation plate 9, and the fourth screw 92 passes through the fourth through hole 93 and is connected to the fourth fixing part 13.

[0045] In this embodiment, the heat-insulating plate 9 is disposed within the premixing chamber 11. Several vent holes 91 are provided on the heat-insulating plate 9 to allow the mixed gas to pass through, thus enabling the premixing chamber 11 to communicate vertically. This allows the heat-insulating plate 9 to block most of the heat radiated from the lower side of the infrared burner 12 to the burner head 1, thereby reducing the temperature rise of the burner head 1 and the interior of the stove. Multiple fourth fixing parts 13 are spaced apart along the circumference of the premixing chamber 11 at the upper end. Correspondingly, multiple fourth through holes 93 are provided on the heat-insulating plate 9. Fourth screws 92 pass through the fourth through holes 93 and connect to the fourth fixing parts 13, thereby fixing the heat-insulating plate 9 within the premixing chamber 11. This ensures that the screws fixing the heat-insulating plate 9 are completely hidden inside the burner. The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
