The plurality of supporting claws 4 correspond to the plurality of upper layer outer mounting holes 1-4-1 one by one, the supporting claws 4 are positioned above the corresponding upper layer outer mounting holes 1-4-1, and the plurality of fasteners 5 sequentially penetrate through the corresponding lower layer outer mounting holes 2-4-1, the middle layer outer mounting holes 6-4-1, the upper layer outer mounting holes 1-4-1 and the supporting claws 4 from bottom to top. Moreover, the fastening piece 5 is surrounded and shielded by the outer vertical annular folded edge 1-5 and the outer bottom annular folded edge 1-6, so that the attractiveness of the energy gathering ring is improved.
The supporting claw 4 is made of metal materials such as brass, cast iron, stainless steel and aluminum alloy, so that the strength is ensured, and meanwhile, the supporting claw 4 is provided with a plurality of teeth, so that the cooker can be prevented from sliding after being placed on the supporting claw 4.
The material of the upper-layer energy-gathering ring 1 is stainless steel, aluminum alloy and the like, and the stainless steel is preferred in consideration of convenience in machining and forming. Meanwhile, the stainless steel has lower heat conductivity, and can reduce the heat transfer with the energy-gathering rings of the middle and lower layers.
The material of the middle-layer energy-gathering ring 6 can be aerogel, stainless steel, aluminum alloy and the like, preferably, the aerogel has extremely low thermal conductivity of about 0.013W/(m/K), and the heat transfer with the lower-layer energy-gathering ring 2 can be effectively reduced.
The material of the lower energy gathering ring 2 is stainless steel, aluminum alloy, cast iron and the like, and the aluminum alloy is preferred in consideration of convenient processing and forming. The material of the fastening piece 5 is preferably stainless steel, so that the heat of the supporting claws 4 cannot be rapidly transferred to the upper-layer energy gathering ring 1.
In this embodiment, the height of the support claw 4 is 5mm to 15 mm. The height of the supporting claw 4 is the height of the supporting claw 4 protruding out of the upper layer outer ring installation folded edge 1-4. The height range of the supporting claws 4 can ensure that the annular gap is formed between the upper layer outer ring mounting folded edge 1-4 and the bottom of the cookware, and the height of the gap is the same as that of the supporting claws 4. If the height of the gap is too small, the high-temperature smoke discharge resistance is too large; if the height of the gap is too large, certain resistance cannot be formed on high-temperature flue gas, the height of the gap is controlled to be 5-15 mm, and certain resistance can be formed on the high-temperature flue gas discharged from a fire hole of the outer fire cover 7, so that the high-temperature flue gas collides with the outer annular inclined plane 1-1 of the upper layer and then contacts the annular bottom surface 1-2 of the upper layer, and then collides with the high-temperature flue gas just discharged from the fire hole through the guiding effect of the inner annular inclined plane 1-3 of the upper layer, the collision process reduces the speed of the flue gas, the retention time of the high-temperature flue gas above the upper layer energy-gathering ring 1 is further prolonged, secondary combustion of the high-temperature flue gas above the upper layer energy-gathering ring 1 is realized, and the heat exchange efficiency of the high.

The inner diameter of the energy-gathering ring is 2-20 mm larger than the outer diameter of the outer fire cover 7; the inner vertical annular folded edge 1-8 is the part with the smallest diameter of the energy gathering ring, so the inner diameter of the energy gathering ring refers to the inner diameter of the inner vertical annular folded edge 1-8, and the inner diameter of the inner vertical annular folded edge 1-8 is 2-20 mm larger than the outer diameter of the outer fire cover 7. The inner edge of the energy gathering ring is 2mm-10mm lower than the fire hole 7-1 of the outer fire cover 7, namely the top end of the inner edge of the inner vertical annular folded edge 1-8 is 2mm-10mm lower than the fire hole 7-1 of the outer fire cover 7. Through the adjustment of the two parameters, the heat of the flame can be effectively isolated on the upper-layer energy accumulation ring 1, meanwhile, the flame sprayed out from the fire hole 7-1 of the outer fire cover 7 sucks secondary air from the bottom of the energy accumulation ring (injection effect, see the dotted arrow in fig. 10) through the gap between the energy accumulation ring and the outer fire cover 7, and the secondary air can directly reach the fire hole 7-1 of the outer fire cover 7, so that the full combustion of the fuel gas sprayed out from the outer fire cover 7 is ensured. Meanwhile, a plurality of secondary air channels 7-2 are formed on the inner peripheral wall of the outer fire cover 7 at intervals along the circumferential direction, and as shown in fig. 9, the secondary air supplements the flame of the inner fire cover 8 through the secondary air channels 7-2, so that the full combustion of the inner ring flame is ensured.
