[0108] Preferably, in the embodiment, the support ring 31 extends downwardly in a direction away from the axis of the fire cover seat 2, and / or the outer periphery of the support ring 31 extends vertically downwardly, which can further improve the shielding effect of the support ring 31 on the decorative cover 11, and avoid the user directly observing the decorative cover 11 from the side of the pot support frame 3.

[0109] Through the above arrangement, the outer edge of the support ring 31 can extend to the outer periphery of the decorative cover 11, and the outer edge of the support ring 31 is close to the panel 1, so that the user can avoid directly observing the decorative cover 11 from the oblique front of the gas stove, and the visual experience of the user is improved. In addition, under the support of the fire cover seat 2 on the pot support frame 3, the outer edge of the support ring 31 is spaced apart from the panel 1, so that part of the secondary air required in the gas combustion process and the primary air sucked in by the ejector pipe in the gas injection process can enter through the gap between the support ring 31 and the panel 1, and the combustion effect is ensured.

[0110] In some preferred embodiments, the support ring 31 has a first extension section 312 extending upwardly away from the axis of the fire cap seat 2, and a second extension section 313 extending vertically downwardly from the outer edge of the support ring 31, in a direction away from the axis of the fire cap seat 2. The first extension section 312 can facilitate the collection of heat generated by the flame towards the bottom of the pot, thereby improving the utilization of heat. Meanwhile, the second extension section 313 can also ensure the shielding effect of the decorative cover 11, thereby ensuring the aesthetics.

[0116] In another possible embodiment, the bottom of the support ring 31 is provided with a second leg 33, and the bottom of the second leg 33 is close to the panel 1 of the gas stove.

[0117] Specifically, the second leg 33 can assist the fire cap seat 2 in supporting the support ring 31. When the weight of the pot supported on the pot support frame 3 is large, the support ring 31 will be deformed, so that the panel 1 can provide a supporting force to the support ring 31 through the second leg 33, thereby improving the stability of the support of the pot by the pot support frame 3.

[0118] Preferably, the bottom of the second leg 33 is attached to the panel 1 of the gas stove, and when the pot support frame 3 does not carry the pot, the second leg 33 does not exert pressure on the panel 1, or a gap is provided between the bottom of the second leg 33 and the panel 1 of the gas stove.

[0121] In the embodiment, the second supporting leg 33 is a plate-shaped structure extending along the radial direction of the supporting ring 31.

[0122] Preferably, in the embodiment, the second supporting leg 33 is arranged with a plurality of second supporting legs 33 corresponding to the first supporting legs 32.

[0123] Preferably, the second supporting leg 33 and the first supporting leg 32 are an integral part formed on the supporting ring 31.

[0124] Preferably, in the embodiment, the bottom of the second supporting leg 33 is arranged with a U-shaped member 34, the U-shaped member 34 is made of flexible material, and the U-shaped member 34 is fixed on the bottom of the second supporting leg 33 to cover the bottom of the second supporting leg 33. The bottom of the second supporting leg 33 contacts the panel 1 through the U-shaped member 34, so that the panel 1 is not scratched when the bottom of the second supporting leg 33 contacts the panel 1.

[0125] In the embodiment, the U-shaped member 34 can be made of silica gel material or heat-resistant rubber material.

[0126] Preferably, in the embodiment, the bottom of the second supporting leg 33 is lower than the bottom of the fire cover seat 2, so that when the user takes down the fire cover seat 2 and the pot support frame 3 and places them, the second supporting leg 33 can support the whole of the fire cover seat 2 and the pot support frame 3, so that the whole of the fire cover seat 2 and the pot support frame 3 can be kept stable, and the bottom of the fire cover seat 2 does not contact the supporting surface for placing the fire cover seat 2 and the pot support frame 3, so that dirt does not enter the ejector pipe.

[0127] In some preferred embodiments, the gas stove further comprises a housing 10, the panel 1 is installed on the top of the housing 10, a cavity is formed between the panel 1 and the housing 10, and the burner 4 is installed in the cavity.
