The second main body 210 is located inside the ring of the third main body 310, and the first main body 110 is located inside the ring of the second main body 210, forming a multi-layer nested structure. A plurality of first supporting portions 111 are spaced apart on the outer peripheral side of the first main body 110, and a plurality of second supporting portions 211 are spaced apart on the outer ring side of the second main body 210.

The structure is simple and convenient for installation and disassembly. In practical applications, in addition to the above structure, the first main body 110, the second main body 210, and the third main body 310 can also be detachably connected through a snap connection structure or a screw connection structure, which can be specifically set according to actual usage needs.

[0042] In some embodiments, the second combustion component 200 further includes a first connecting member 220, and the third combustion component 300 further includes a second connecting member 320. A first connection hole 103 is provided on the first supporting portion 111, and a second connection hole 203 is provided on the second supporting portion 211.

[0043] It can be understood that as Figure 3 、 Figure 4 and Figure 5 shown, both the first connecting member 220 and the second connecting member 320 are threaded members. Through holes for the corresponding connecting members to pass through are provided on the second main body 210 and the third main body 310. During connection, the first connecting member 220 passes through the second main body 210 and is threadedly engaged with the first connection hole 103 on the first supporting portion 111, and the second connecting member 320 passes through the third main body 310 and is threadedly engaged with the second connection hole 203 on the second supporting portion 211, realizing the connection and fixation between the main body and the supporting portion, which can improve the connection stability between the first combustion component 100, the second combustion component 200, and the third combustion component 300 and is convenient for use. In practical applications, the first connecting member 220 and the second connecting member 320 can also be pins, which pass through the corresponding main bodies and are connected and fixed with the corresponding connection holes in the form of shaft-hole cooperation. Or, the connecting member passes through the corresponding main body and supporting portion and is threadedly connected with a nut at the lower end to realize the connection and fixation between the main body and the supporting portion, which can be specifically set according to actual usage needs.

[0044] In some embodiments, both the first combustion structure and the second combustion structure include a gas nozzle 120, and the gas in the first gas channel 101 and the gas in the second gas channel 201 can be output through the corresponding gas nozzles 120 respectively.

[0045] It can be understood that, as Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the first combustion structure, the second combustion structure and the third combustion structure all include gas nozzles 120. A plurality of gas nozzles 120 are provided and are respectively connected to the first main body 110, the second main body 210 and the third main body 310. In use, the gas in the first gas channel 101 can be output through the gas nozzle 120 on the first main body 110 for combustion, the gas in the second gas channel 201 can be output through the gas nozzle 120 on the second main body 210 for combustion, and the gas in the third gas channel 301 can be output through the gas nozzle 120 on the third main body 310 for combustion. Its structure is simple and convenient to use.

[0046] In actual application, in addition to the above structure, the first combustion structure, the second combustion structure and the third combustion structure can also output gas through flame holes. For example, a burner cap is provided on the upper side of the first main body 110, the second main body 210 and the third main body 310, and flame holes are provided on the burner cap. The flame holes are communicated with the corresponding gas channels to supply the gas in the corresponding gas channels to output. Of course, the combustion structures of different combustion components can also be different. For example, the first combustion structure uses the gas nozzle 120 to output gas, and the second combustion structure can use flame holes to output gas, which can be changed accordingly according to actual use needs.

[0047] In some embodiments, both the first combustion structure and the second combustion structure include a gas guiding member 230. The gas guiding member 230 has a guiding wall 204. The output end of the gas nozzle 120 faces upward and corresponds to the guiding wall 204, so that the gas output by the gas nozzle 120 can be sprayed onto the guiding wall 204 and spread along the guiding wall 204 to form a gas film.

[0048] It can be understood that, as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the first combustion structure, the second combustion structure, and the third combustion structure all include an air guiding member 230. A plurality of air guiding members 230 are provided and are respectively arranged on the first main body 110, the second main body 210, and the third main body 310. Each air guiding member 230 is provided with a guiding wall 204. The output end of each gas nozzle 120 is inclined upward and faces the guiding wall 204 on the corresponding air guiding member 230. When the gas in the gas passage is ejected through the gas nozzle 120, the gas ejected by the gas nozzle 120 is ejected onto the corresponding guiding wall 204. After the ejected air flow collides with the guiding wall 204, the flow direction changes, causing the air flow to spread on the wall surface and form an air film along the guiding wall 204, thereby increasing the contact area between the output gas and air, which is beneficial to improving the combustion efficiency of the gas and saving energy. In actual application, the specific number of the air guiding members 230 can be set accordingly according to actual usage needs.

[0049] In some embodiments, the air guiding member 230 is annular, and the guiding wall 204 is arranged on the outer side and / or the inner side of the ring of the air guiding member 230. It can be understood that, as Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the air guiding member 230 is circular, and the guiding wall 204 is arranged on the inner side of the ring of the air guiding member 230. Each air guiding member 230 is correspondingly provided with a plurality of gas nozzles 120 distributed at intervals. When the gas ejected by the plurality of gas nozzles 120 burns on the guiding wall 204, a ring-shaped flame can be formed. The plurality of air guiding members 230 cooperate to form multiple rings of flames to achieve a better cooking heating effect. In actual application, a plurality of air guiding members 230 can be arranged on the first main body 110, the second main body 210, and the third main body 310. The guiding wall 204 can also be arranged on the outer side of the ring of the air guiding member 230, and can be specifically set accordingly according to actual usage needs.

[0050] To achieve the ignition of the gas between multiple combustion components, the vertical height dimension of the air guiding member 230 and the distance dimension between two adjacent air guiding members 230 can be set to be smaller, which is beneficial to the flame on the air guiding member 230 inside the circle to ignite the gas on the air guiding member 230 outside the circle. Or, a fire guiding groove can be arranged on the air guiding member 230 to guide the flame to the outer side of the ring of the air guiding member 230 to ignite the outer gas. Of course, if the combustion structure is a combustion with gas outlet from the fire holes, a corresponding fire guiding groove can also be arranged for the ignition of the gas, which can be specifically set accordingly according to actual usage needs.

[0051] In some embodiments, the guiding wall 204 is frustum-shaped or inverted frustum-shaped. It can be understood that, as Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, the inner profile diameter of the air guide member 230 gradually decreases in the upward direction, so that the guiding wall 204 is frustum-shaped, which can guide the flame on the guiding wall 204 towards the center, concentrate the firepower, and is beneficial to achieving a better heating effect. In actual application, the guiding wall 204 can also be an inverted frustum shape to guide the flame on the guiding wall 204 outwards, increasing the firepower coverage range of the fire ring. Or the guiding wall 204 on part of the air guide member 230 is frustum-shaped, and the guiding wall 204 on part of the air guide member 230 is inverted frustum-shaped. Or the inner and outer sides of the ring of the same air guide member 230 are respectively provided with frustum-shaped and inverted frustum-shaped guiding walls 204, which can be specifically set according to actual usage needs.

[0052] In some embodiments, the first combustion assembly 100 includes a first main body 110, the second combustion assembly 200 includes a second main body 210, and positioning portions 311 are provided on both the first main body 110 and the second main body 210. The positioning portions 311 are used to limit the placement position of the air guide member 230.

[0053] It can be understood that as Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, ring-shaped positioning portions 311 are provided on the first main body 110, the second main body 210, and the third main body 310. When a plurality of air guide members 230 are respectively placed on the first main body 110, the second main body 210, and the third main body 310, each air guide member 230 is located within the circle surrounded by the corresponding positioning portion 311. The positioning portion 311 is used to limit the placement position of the air guide member 230, reducing the possibility of its movement and loosening, which is convenient for use. In actual application, the air guide member 230 can also be connected to the first main body 110, the second main body 210, and the third main body 310 through a threaded structure or a clamping structure, etc., which can be specifically set according to actual usage needs.
