These protrusions 901 can be at the same height as the inner wall of the second oil cup 900. Each protrusion 901 has a through-hole for the thermocouple 500 and the igniter 600, respectively. In practice, the height of the two leak-proof protrusions 901 can be slightly less than, or even equal to, the height of the inner wall of the second oil cup 900, or even higher, to prevent the liquid held by the second oil cup 900 from leaking out through the through-holes.

In combination Figures 7-10 , the first combustion part 300 comprises a first plate body 301 and a second plate body 302, wherein the first plate body 301 is arranged above the second plate body 302, the outer side edge of the first plate body 301 is provided with a first connecting plate 303, the inner side of the first connecting plate 303 is provided with a connecting groove 304, the outer side edge of the second plate body 302 is provided with a second connecting plate 305, the second connecting plate 305 is connected into the connecting groove 304 of the first connecting plate 303, the first connecting plate 303 and the second connecting plate 305 are configured as a lapping part, which is arranged at the outer side edge of the first combustion part 300 and is clamped by the clamping part 402 and the stop 202 of the support arm 200. The lapping part is annular, which is arranged in the annular recess formed by the stop 202 of the support protrusion of the plurality of support arms 200.

[0056] In combination Figure 10 , in an embodiment, the middle part of the first connecting plate 303 is bent to form the connecting groove 304, and the second connecting plate 305 can be assembled in the connecting groove 304 by welding. In another embodiment, the first plate body 301 and the second plate body 302 can also be directly welded to form the lapping part.

[0057] In combination Figure 9 , the middle part of the first plate body 301 and the second plate body 302 is bent inward to form a narrow channel inside the first combustion part 300, so as to divide the cavity formed by the first plate body 301 and the second plate body 302 into an air inlet cavity 306 located at the lower part and a combustion cavity 307 located at the upper part. The inner side wall of the upper part of the first plate body 301 and the second plate body 302 is configured as a plurality of semicircular holes arranged at intervals around the central axis of the first combustion part 300, so as to form a plurality of fire hole structures in the combustion cavity 307. A partition plate 308 can also be arranged in the combustion cavity 307, which is arranged between the first plate body 301 and the second plate body 302, so as to form inner and outer flames in the combustion cavity 307 of the first combustion part 300, thereby improving the combustion efficiency of the first combustion part 300.

[0058] In combination Figures 7-9At least part of the lower part of the first plate body 301 and the second plate body 302 is bent to the outside of the first combustion part 300, so that the air inlet cavity 306 of the first combustion part 300 has a larger accommodation space. The burner further comprises a first injection part 309 connected to the outside of the first combustion part 300 and communicating with the inside of the first combustion part 300, i.e. the air inlet cavity 306. The gas can be introduced into the air inlet cavity 306 of the first combustion part 300 through the first injection part 309 and mixed with air. The gas mixed with the gas and air enters the combustion cavity 307 for combustion of the first combustion part 300. Since the air inlet cavity 306 of the first combustion part 300 has a larger accommodation space, it can accommodate more air and gas, thereby improving the combustion efficiency of the first combustion part 300.

In another embodiment, the first injection part 309 and the second injection part 111 can be separately provided, and the present application does not limit this.

[0060] In combination with Figure 9 The top of the partition plate 308 is inclined towards the inside of the first combustion part 300, so that the flame formed by the first combustion part 300 burns inwardly to form the above-mentioned flame-converging burner. Of course, the flame of the first combustion part 300 can also be directed outwardly, and the present application does not limit this.

[0061] In combination with Figure 5 In some embodiments, the support arm 200 is provided with a recess 203, and at least part of the bottom of the first combustion part 300 is arranged in the recess 203, so as to reduce the size of the burner in the height direction when the content capacity of the air inlet cavity 306 of the first combustion part 300 is as large as possible, reduce the production cost, and also can be positioned in the radial direction of the first combustion part 200 to avoid the first combustion part 300 from shaking in the radial direction.

In combination with Figure 10According to an embodiment of the present application, the fixing member 400 is substantially annular in structure and is arranged on the top surface of the first plate body 301 of the first combustion part 300. The fixing part 401 can be block-shaped in structure and can be integrally formed on the outer circumferential side of the fixing member 400. The fixing part 401 can be fixedly connected to the corresponding support protrusion 201 by means of a bolt. The fixing part 401 has a portion protruding from the stopper 202. This portion can be configured as a clamping portion 402 of the fixing part 401. The clamping portion 402 and the stopper 202 of the support protrusion 201 clamp the lap portion of the first combustion part 300, so as to fix and assemble the first combustion part 300 with the base 100, thereby preventing the safety problem of the burner caused by shaking to a certain extent and having good practicability.

[0063] In combination Figure 10 According to an embodiment of the present application, the fixing part 401 can be a plate-shaped structure and can be formed by bending. The transition of the fixing part 401 can be configured as the clamping portion 402.

[0064] In an embodiment, the fixing member 400 can be assembled on the top surface of the first plate body 301 of the first combustion part 300 by means of a bolt or the like. In another embodiment, the fixing member 400 can also be assembled on the top surface of the first plate body 301 of the first combustion part 300 separately.
