Preferably, a flared section 115 is formed near the inner annular air inlet 112. The diameter of the flared section 115 is larger than that of other portions of the inner annular mixing tube 11. The placement of these openings 114 on the flared section 115 allows for a better intake volume. The inner annular air inlet 112 can be connected to a gas nozzle 3. Fuel is then delivered to the furnace assembly 2 via the gas nozzle 3, sequentially passing through the inner annular air inlet 112, the inner annular mixing channel 111, and the inner annular air outlet 113. Air intake can be controlled through openings 114 below the straight tube to adapt to different environments, reduce combustion problems, reduce pressure loss, increase primary air volume, make combustion more complete, and reduce exhaust gas. The primary air volume can be increased by approximately 12% compared to conventional structures.

The outer ring mixing tube 12 is made of stainless steel sheet metal. An outer ring mixing channel 121 is formed inside the outer ring mixing tube 12 (as shown in Figures 7 to 9). One end of the outer ring mixing tube 12 has an outer ring air inlet 122, and the other end of the outer ring mixing tube 12 has an outer ring air outlet 123. The outer ring air outlet 123 is annular, so that the gas The gas can be output in a circular shape. The outer mixing channel 121 is located between the outer air inlet 122 and the outer air outlet 123. The outer mixing channel 121 connects the outer air inlet 122 and the outer air outlet 123. Preferably, the outer mixing channel 121 is a conical channel, with the inner diameter of the outer mixing channel 121 increasing from the outer air inlet 122 to the outer air outlet 123. The fuel gas can be delivered to the furnace assembly 2 in sequence through the outer air inlet 122, the outer mixing channel 121, and the outer air outlet 123.

Referring to Figures 7 to 9 , the outer annular mixing tube 12 can be a two-piece design to facilitate its manufacture. The outer annular mixing tube 12 can include an upper shell 124 and a lower shell 125. The upper shell 124 and the lower shell 125 can be stamped separately. The upper shell 124 is positioned above the lower shell 125, and the two are then connected and assembled to form the outer annular mixing channel 121 between the upper shell 124 and the lower shell 125. The outer annular mixing tube 12 can be manufactured by combining the upper shell 124 and the lower shell 125.

In this embodiment, the edges of the upper shell 124 and the lower shell 125 extend to form a first fold 1241 and a second fold 1251 respectively. The first fold 1241 and the second fold 1251 are combined with each other, so that the upper shell 124 and the lower shell 125 are connected into one body by the fold structure. In this embodiment, the first fold 1241 and the second fold 1251 are horizontal (as shown in Figures 8 and 9), the first fold 1241 is overlapped on top of the second fold 1251, and one end of the first fold 1241 extends to an appropriate length so that one end of the first fold 1241 can be bent downward to the bottom of the second fold 1251, so that the first fold 1241 can be clamped outside the second fold 1251, so that the edge of the upper shell 124 and the edge of the lower shell 125 can be firmly combined, and the seam cannot be seen from above, which is more beautiful. In another embodiment (not shown), for example, one end of the second fold 1251 can be extended so that one end of the second fold 1251 can be bent upward to above the first fold 1241, so that the second fold 1251 can be clamped outside the first fold 1241, so that the upper shell 124 and the lower shell 125 are connected into one body using the fold structure.

The inner ring furnace head 21 is hollow, and its lower end can be sleeved onto the inner ring air outlet 113 of the inner ring mixing tube 11, allowing the inner ring furnace head 21 to be assembled with the inner ring air outlet 113 of the inner ring mixing tube 11. The interior of the inner ring furnace head 21 is connected to the inner ring air outlet 113, and the outer ring furnace head 22 can be assembled with the outer ring air outlet 123 of the outer ring mixing tube 12.

The outer ring furnace head 22 may include an inner ring portion 221 and an outer ring portion 222. The inner ring portion 221 and the outer ring portion 222 are both annular. The inner ring portion 221 and the outer ring portion 222 are vertically arranged. The outer ring portion 222 is located outside the inner ring portion 221. The inner ring portion 221 and the outer ring portion 222 are spaced apart to form an annular flow channel 223 between the inner ring portion 221 and the outer ring portion 222.

The lower end of the inner annular portion 221 may extend toward the center to form a first flange 224, which is disposed around the inner side of the inner annular portion 221. The lower end of the outer annular portion 222 may extend toward the center to form a second flange 225, which is disposed around the inner side of the outer annular portion 222. The lower ends of the inner annular portion 221 and the outer annular portion 222 may be connected to the other end of the outer annular mixing tube 12, so that the outer annular gas outlet 123 of the outer annular mixing tube 12 is coupled to the outer annular furnace head 22 of the furnace head assembly 2, and the annular flow channel 223 is connected to the outer annular gas outlet 123.

In this embodiment, the other end of the outer ring mixing tube 12 extends to form a third fold edge 126 and a fourth fold edge 127. The third fold edge 126 is extended and bent from the other end of the outer ring mixing tube 12 so that the third fold edge 126 can be clamped outside the first flange 224 of the inner ring portion 221. The fourth fold edge 127 is extended and bent from the other end of the outer ring mixing tube 12 so that the fourth fold edge 127 can be clamped outside the second flange 225 of the outer ring portion 222, so that the outer ring air outlet 123 of the outer ring mixing tube 12 can be stably combined with the outer ring furnace head 22 of the furnace head group 2. The third folded edge 126 and the fourth folded edge 127 are both three-fold structures that can be bent to form a U-shape, which has a better clamping effect and can stably combine the outer ring mixing tube 12 and the outer ring furnace head 22.

In this embodiment, an inner ring tooth cover 4 and an outer ring tooth cover 5 are respectively provided on the inner ring furnace head 21 and the outer ring furnace head 22 (as shown in Figures 1 to 4). The inner ring tooth cover 4 can be a circular cover, and the outer ring tooth cover 5 can be a ring-shaped cover. The inner ring tooth cover 4 can be used to close the upper end of the inner ring furnace head 21, and the outer ring tooth cover 5 can be used to close the upper end of the inner ring furnace head 21. The gear cover 5 can be used to seal the upper end of the annular flow channel 223. A plurality of inner ring flame holes 41 are spaced apart on the inner ring gear cover 4. These inner ring flame holes 41 are connected to the interior of the inner ring furnace head 21, allowing combustion gas to be transported to the inner ring furnace head 21 and the inner ring gear cover 4 through the inner ring mixing tube 11, and flames are ejected from these inner ring flame holes 41. The outer ring gear cover 5 is provided with a plurality of outer ring flame holes 51 at intervals. These outer ring flame holes 51 are connected to the annular flow channel 223, so that the combustion gas can be transported to the outer ring furnace head 22 and the outer ring gear cover 5 through the outer ring mixing pipe 12, and the flames are ejected from these outer ring flame holes 51.

In this embodiment, a soup pan 6 (as shown in Figure 4) can be positioned between the inner and outer ring furnace heads 21, 22. The soup pan 6 comprises an upper cover 61 and a lower cover 62. The upper cover 61 is positioned above the lower cover 62, and the upper and lower covers 61 and 62 are joined. The upper and lower covers 61 and 62 are respectively provided with a plurality of upper through-holes 611 and a plurality of lower through-holes 621. These staggered holes 611 and 621 prevent the soup from directly seeping into the interior of the furnace, making cleaning easier. They also direct secondary air to the base of the flame, ensuring more complete combustion and reducing exhaust gas.
