Thus, the gas in the inner ring gas mixing cavity 20a can be uniformly provided to the annular inner ring fire gap 241 through the plurality of inner ring fire holes 23 for combustion, thereby improving the stability of the inner ring gap flame.

[0077] Referring to Figures 10 to 14As shown, in some embodiments, a flame stabilizing groove 26 can be concavely arranged on the top surface of the middle ring fire cover 2. The flame stabilizing groove 26 can be a concave arc-shaped groove structure. The inner ring fire hole 23 can be arranged on the groove bottom surface of the flame stabilizing groove 26. The inner ring top cover 24 can be arranged in the flame stabilizing groove 26. The circumferential side edge of the inner ring top cover 24 and the circumferential side edge of the flame stabilizing groove 26 can be arranged in a spaced manner. The inner ring fire gap 241 can be formed between the bottom surface of the inner ring top cover 24 and the groove bottom surface of the flame stabilizing groove 26. Therefore, the inner ring gap flame formed by the combustion of the gas at the inner ring fire gap 241 can be arranged within the contour of the flame stabilizing groove 26, effectively avoiding the influence of the external environment on the inner ring gap flame, and facilitating the stability of the inner ring gap flame. The flame stability of the burner under small fire combustion or extremely small fire combustion is improved, and the low-temperature cooking demand is met.

[0078] As shown in FIG. 1, the burner 1 can include a middle ring fire cover 2, an inner ring top cover 24, and an inner ring fire cover 25. Figures 12 to 13 As shown, in some embodiments, the circumferential side edge of the flame stabilizing groove 26 can be formed with a separation eave 261. The separation eave 261 can be annular, and the separation eave 261 can be circumferentially arranged at the circumferential side edge of the flame stabilizing groove 26. The separation eave 261 and the inner ring top cover 24 can be arranged in a spaced manner, so that the separation eave 261 can be arranged in a spaced manner around the circumferential side of the inner ring top cover 24. Therefore, the inner ring gap flame formed by the combustion of the gas at the inner ring fire gap 241 can be arranged within the contour of the separation eave 261, effectively avoiding the influence of the external environment on the inner ring gap flame, and facilitating the stability of the inner ring gap flame. For example, the suction effect of the middle ring flame on the inner ring gap flame can be avoided, and the state of the inner ring gap flame being clear and stable is facilitated.

[0079] In some embodiments, the top height of the separation eave 261 can be higher than the top surface height of the inner ring top cover 24. The height of the separation eave 261 is higher than the top surface height of the inner ring top cover 24, so that the height of the inner ring gap flame can be lower than the top height of the separation eave 261. The influence of the external environment (such as wind) on the inner ring gap flame can be avoided, the protection effect of the separation eave 261 on the inner ring gap flame is improved, and the stability of the inner ring gap flame is improved.

[0080] It should be noted that, in other embodiments, the top height of the separation eave 261 can also be equal to or lower than the top surface height of the inner ring top cover 24.

[0081] As shown in FIG. 1, the burner 1 can include a middle ring fire cover 2, an inner ring top cover 24, and an inner ring fire cover 25. Figures 12 to 13 As shown, in some embodiments, the separation eave 261 can be arranged by extending outward and upward in an arc shape from the circumferential side edge of the top surface of the middle ring fire cover 2. Therefore, the separation eave 261 can be partially arranged above the top of the middle ring fire hole 21. The separation eave 261 can effectively isolate the middle ring flame and the inner ring gap flame from each other.

[0082] As shown in FIG. 1, the burner 1 can include a middle ring fire cover 2, an inner ring top cover 24, and an inner ring fire cover 25. Figures 12 to 13As shown, in some embodiments, a waterproof step 262 can be protruded on the bottom surface of the flame stabilizing groove 26. The waterproof step 262 can be annular. The waterproof step 262 can be arranged around the periphery of the inner annular flame hole 23. A plurality of inner annular flame holes 23 can be arranged inside the waterproof step 262. The height of the waterproof step 262 can be higher than the inner annular flame hole 23. Therefore, when liquid drips into the flame stabilizing groove 26, the liquid can also be blocked outside the waterproof step 262, avoiding the liquid flowing directly into the inner annular flame hole 23 and the inner annular mixing cavity 20a, so as to avoid affecting the mixing effect and the combustion effect.

[0083] In some embodiments, the inner annular top cover 24 can cover above the top of the waterproof step 262. The peripheral edge of the inner annular top cover 24 can be arranged on the outer periphery of the waterproof step 262. Therefore, when liquid drips from the inner annular top cover 24, it can be ensured that the liquid drips outside the waterproof step 262, avoiding the liquid flowing directly into the inner annular flame hole 23.

[0084] Please refer to Figures 10 to 14 As shown, in some embodiments, a middle annular transfer flame gap 27 can be formed on the middle annular flame cover 2. The middle annular transfer flame gap 27 can be exposed on the top surface and the peripheral wall of the middle annular flame cover 2. The middle annular transfer flame gap 27 can be arranged extending radially towards the center of the middle annular flame cover 2.

[0085] In some embodiments, the middle annular transfer flame gap 27 can be communicated with the middle annular mixing cavity 20b. The middle annular transfer flame gap 27 can be communicated with the middle annular flame stabilizing gap 22, and the middle annular transfer flame gap 27 can be communicated with the middle annular mixing cavity 20b through the middle annular flame stabilizing gap 22. The ignition needle 15 can be arranged at intervals on the outer periphery of the middle annular flame stabilizing gap 22. Therefore, the gas can enter the middle annular transfer flame gap 27 through the middle annular flame stabilizing gap 22, and the gas in the middle annular transfer flame gap 27 can be ignited by the ignition needle 15, thereby igniting the gas in the middle annular flame stabilizing gap 22 and the middle annular flame hole 21, and further igniting the middle annular flame.

[0086] In some embodiments, the middle annular transfer flame gap 27 can be communicated with the inner annular mixing cavity 20a. The middle annular transfer flame gap 27 can be arranged extending radially towards the center of the middle annular flame cover 2. The middle annular transfer flame gap 27 can be communicated with the flame stabilizing groove 26. The inner end of the middle annular transfer flame gap 27 can extend to the peripheral edge of the inner annular flame gap 241. Therefore, the ignition needle 15 can ignite the gas in the inner annular flame gap 241 through the middle annular transfer flame gap 27, thereby igniting the inner annular flame.

[0087] In some embodiments, the middle annular transfer flame gap 27 can be formed on the outer peripheral wall of the isolation eave 261. The middle annular transfer flame gap 27 is arranged extending from the peripheral edge of the isolation eave 261 towards the center of the flame stabilizing groove 26.

[0088] Please refer to Figures 11 to 12As shown, in some embodiments, the middle ring transfer gap 27 can be formed with a transfer groove 271 at the isolation eave 261. The transfer groove 271 can be formed by recessing one side or both sides of the middle ring transfer gap 27. The width of the transfer groove 271 can be greater than the width of the inner end of the middle ring transfer gap 27. A stepped surface 272 can be formed between the transfer groove 271 and the inner end of the middle ring transfer gap 27. The space in the transfer groove 271 can be a secondary air supplement space. When the gas enters the transfer groove 271, the gas outlet velocity of the mixed gas can be effectively reduced, and the flame transfer flame can be prevented from appearing.

[0089] In some embodiments, the stepped surface 272 at the transfer groove 271 can form a flame stopping surface. When the gas burns in the transfer groove 271, the flame in the middle ring transfer gap 27 inside or below the flame stopping surface can be hidden, the influence of the external environment on the flame transfer flame can be reduced, and the effect of the inner ring flame on the middle ring flame can be ensured.

[0090] Please refer to Figures 12 to 14 As shown, in some embodiments, the top of the inner ring gas mixing cavity 20a is arranged to extend towards the outer peripheral direction of the middle ring fire cover 2. The gas transfer cavity 20c can extend radially outward from the top of the middle ring gas mixing cavity 20b to the outer peripheral wall of the middle ring fire cover 2. The middle ring transfer gap 27 can communicate with the gas transfer cavity 20c. Therefore, the inner ring gas mixing cavity 20a can communicate with the middle ring transfer gap 27 through the gas transfer cavity 20c.

[0091] In some embodiments, the gas transfer cavity 20c can be recessed only inside the middle ring fire cover 2. The gas transfer cavity 20c can not be distributed in the burner 1.
