The first boss 510 is a simple boss structure, with low production difficulty and low production cost. Through the cooperation and abutment between the first boss 510 and the inner wall of the plane, the first channel 515 is directly formed between a plurality of adjacent first bosses 510, so that the processing of the air passage is changed from the traditional complex core pulling operation to a simple boss processing operation, thereby greatly reducing the cost required for production and processing. The first through hole 240 and the second through hole 320 can ensure that when the burner is in operation, the air under the burner can enter the fire cover 300 and mix with the gas, so that the gas can be fully burned.

[0045] In some embodiments, the fire cover seat 200 and the fire cover 300 are made of sheet metal integrally formed. Sheet metal has the advantages of simple processing and low processing cost. By making the fire cover 300 and the fire cover 200 integrally formed by sheet metal, the cost required for processing can be effectively reduced.

[0046] In some embodiments, the plurality of first bosses 510 are evenly distributed around the first connecting hole 230 .

[0047] In certain embodiments, reference Figure 5The first boss 510 is arranged on the inner plane wall of the fire cover seat 200, and the inner plane wall of the fire cover 300 is provided with a second boss 520 corresponding to and abutting the first boss 510. A second channel 525 is arranged between every two adjacent second bosses 520, and the first channel 515 and the second channel 525 are connected to each other to form an air passage. The mutual abutment of the first boss 510 and the second boss 520 provides a connection positioning point for the fire cover 300 and the fire cover seat 200, thereby ensuring that the fire cover 300 can be accurately installed on the fire cover seat 200.

[0048] In certain embodiments, reference Figure 8 and Fig. 9 The second boss 520 is provided with a third boss 550, and a connecting structure is provided on the third boss 550, and the third boss 550 is connected to the first through hole 240 through the connecting structure. The third boss 550 is connected to the first through hole 240 through the connecting structure, so that the first boss 510 and the second boss 520 are fixed to each other, and then the fire cover 300 and the fire cover seat 200 are relatively fixed and difficult to separate.

[0049] In certain embodiments, reference Figure 8 and Fig. 9 The connection structure includes a connection groove 522 disposed on the side wall of the third boss 550, and the side wall of the first through hole 240 is located in the connection groove 522. The side wall of the first through hole 240 is embedded in the connection groove 522, so that the first through hole 240 and the third boss 550 are relatively clamped and fixed. Therefore, the fire cover 300 is stably installed on the fire cover seat 200.

[0050] In some embodiments, the connection structure includes a first hook (not shown) and a second hook (not shown) connected to each other, the first hook is disposed on the first boss 510, and the second hook is disposed on the second boss 520. The first hook and the second hook are connected to each other, so that the first boss 510 and the second boss 520 are relatively fixed, thereby forming an airway.

[0051] In certain embodiments, reference Figure 6 The bottom of the fire cover 300 is provided with a disc-shaped fourth boss 590, and a plurality of second bosses 520 are evenly arranged on the fourth boss 590, and the fourth boss 590 is raised relative to the bottom edge of the fire cover 300. The protrusion of the fourth boss 590 makes the horizontal height of the second channel 525 lower than that of the bottom edge of the fire cover 300, so that when the edge of the fire cover 300 blocks the first cavity, the space of the cavity at the edge of the fire cover 300 can be expanded, so that the gas can contact with more air, thereby making the combustion of the gas more complete.

[0052] In certain embodiments, reference Figure 3 , Figure 4 and Figure 7 The edge of the fire cover 300 is provided with a fixing structure fixed to the edge of the fire cover seat 200. The fixing structure can not only relatively fix the fire cover 300 and the fire cover seat 200, but also ensure that the gas will not leak from the connection between the fire cover 300 and the fire cover seat 200, thereby preventing accidents.

[0053] In certain embodiments, reference Figure 4 The fixing structure includes a flange 205 arranged on the outer wall of the fire cover seat 200, and a U-shaped connecting portion 305 is arranged at the edge of the fire cover 300, and the flange 205 is located at the recess of the connecting portion 305. The flange 205 is stuck in the U-shaped connecting portion 305, so that the fire cover 300 and the fire cover seat 200 can be effectively connected together and prevent the leakage of gas.

[0054] In certain embodiments, reference Fig.10 and Fig.11 The fixing structure includes a folded edge 310 disposed at the edge of the fire cover 300, and the folded edge 310 covers the side wall of the fire cover seat 200. The folded edge 310 gradually tilts toward the inside of the fire cover 300, so that when the fire cover 300 is installed on the fire cover seat 200, an interference fit will be formed between the two, so that the fire cover 300 and the fire cover seat 200 are tightly connected together.

[0055] In some embodiments, the folded edge 310 gradually tilts toward the outside of the fire cover 300, so that when the fire cover 300 is installed on the fire cover seat 200, an interference fit is formed between the side wall of the fire cover 300 and the folded edge 310, so that the fire cover 300 and the fire cover seat 200 are tightly connected together.

[0056] In some embodiments, the side wall of the fire cover seat 200 is wrapped around the outer side of the folded edge 310, so that the fire cover 300 and the fire cover seat 200 are tightly connected together.

[0057] In certain embodiments, reference Figure 6, a ring-shaped connector 700 is provided at the bottom of the fire cover seat 200, and a plurality of card platforms 710 are provided on the inner side wall of the connector 700, and the plurality of card platforms 710 are provided one by one between the inner ends of each adjacent two first channels 515; a mounting groove 720 for mounting a safety pin 810 and an ignition pin 820 is provided on the outer side wall of the connector 700, and the mounting groove 720 is located below the first through hole 240. The connector 700 is relatively positioned between the card platform 710 and the fire cover seat 200. At the same time, since the safety pin 810 or the ignition pin 820 needs to pass through the first through hole 240 and the second through hole 320 to reach the top of the fire cover 300 and ignite, the connector 700 is also relatively positioned with the fire cover 300 through the mounting groove 720. As a result, the fire cover 300 and the fire cover seat 200 are relatively positioned through the connector 700, thereby ensuring that the first channel 515 and the second channel 525 are connected.

[0058] In certain embodiments, reference Figure 5 and Figure 6 A second connection hole 350 is provided in the middle of the fire cover 300, and the center line of the second connection hole 350 is on the same straight line as the center line of the connection hole 230. An inner ring cover 400 is provided on the fire cover 300, and the inner ring cover 400 blocks the second connection hole 350. The second connection hole 350 allows the gas to be divided into an inner ring fire and an outer ring fire after passing through the fire cover seat 200, so as to meet different usage requirements. One end of the second connection hole 350 is connected to the inner ring cover 400, and the other end can be connected to the gas connection pipe, so as to ensure that the gas of the inner ring fire and the gas of the outer ring fire are relatively separated.

[0059] In certain embodiments, reference Figure 3 and Figure 6 The fire cover 300 is provided with a step position for connecting the inner ring cover 400. The step position can not only fix the inner ring cover 400, but also provide a positioning point for the inner ring cover 400, so that the inner ring cover 400 can be stably fixed on the fire cover 300 and block the second connection hole 350.

[0060] refer to Figure 1 , Figure 2 and Figure 3 According to an embodiment of the present invention, a burner is further provided, comprising any of the above-mentioned ignition distributor assemblies. Through the cooperation and abutment of the first boss 510 and the second boss 520, an air passage is directly formed between a plurality of adjacent first bosses 510 and a plurality of adjacent second bosses 520, so that the processing of the air passage is changed from the traditional complex core pulling operation to a simple boss processing operation, thereby greatly reducing the cost required for production and processing.

[0061] In certain embodiments, reference Figure 1 and Figure 3The burner is provided with an inner fire ventilation pipe 110 and an outer fire ventilation pipe 120, the inner fire ventilation pipe 110 is connected to the second connection hole 350, the outer fire ventilation pipe 120 is connected to the connection hole 230, and a part of the inner fire ventilation pipe 110 is nested in the outer fire ventilation pipe 120. The inner fire ventilation pipe 110 and the outer fire ventilation pipe 120 can simultaneously transport gas, thereby ensuring that the inner ring fire and the outer ring fire can burn independently.
