Alternatively, the burner head 1 may also be provided with a spare inlet / outlet seat 14. The spare inlet / outlet seat 14 and the main inlet / outlet seat 13 have the same structure. The burner head 1 adopts this structure, which is suitable for single-ejector tube and double-ejector tube burner seats. The two types use the same set of molds, saving mold costs. The spare inlet / outlet seat 14 may also be called a reserved center inlet / outlet seat, which is matched with the center ejector tube of the burner seat.

[0041] The ignition distributor seat 2 includes a central flame cap seat 21, an outer ring gas channel 22, an outer ring premixing chamber 23, a main injector tube 24, a gas guide tube 25 with openings at both ends, and a connecting plate 26. The outer ring premixing chamber 23 is located at the rear of the outer ring gas channel 22 and communicates with it. The connecting plate 26 is connected to the central flame cap seat 21 and the inner ring wall of the outer ring gas channel 22. The main injector tube 24 and the gas guide tube 25 are arranged side by side and connected to the lower surface of the connecting plate 26, with their rear ends communicating with the outer ring premixing chamber 23. The main injector tube 24 and the gas guide tube 25 intersect with the central flame cap seat. 5. The middle part is connected to the central burner seat 21; the front part of the gas guide tube 25 is provided with a plug; the gas guide tube 25 and the main ejector tube 24 are arranged side by side, i.e., left and right; in the embodiment, the plug is provided at the front part of the gas guide tube 25, and the rear end of the gas guide tube 25 is connected to the outer ring premixing chamber 23, which is suitable for a single ejector tube; when the front end of the gas guide tube 25 and the rear end of the gas guide tube 25 are closed, the gas guide tube serves as the central ejector tube, which is suitable for a double ejector tube burner; with this design, the single ejector tube and the double ejector tube modes share a set of molds, saving mold costs; the inner cavity of the gas guide tube is machined and drilled.

[0042] Flame distributor seat 2 is located on head 12. Main inlet / outlet gas seat 13 and spare inlet / outlet gas seat 24 support the front of outer ring gas tank 22. Outer ring premix chamber 23 is supported and engaged with head 12. The nozzle on the horizontal nozzle hole is opposite to the main ejector tube 24. Center flame cap 3 and outer ring flame cap are respectively engaged with center flame cap seat 21 and outer ring gas tank 22.

[0043] As a further improvement to this novel invention: such as Figure 10 As shown, the front part of the fire distributor seat 2 is provided in the upper air cavity 27 of the lower opening and the front opening;

[0044] like Figure 9 , Figure 11 As shown, the outer ring gas tank 22 is also provided with a left gas passage 221 and a right gas passage 222.

[0045] like Figure 11 As shown, the width H1 of the left gas channel 221 and the right gas channel 222 is smaller than the width H2 of the outer ring gas channel 22, and there is a gap between them and the outer ring wall plate of the outer ring gas channel 22; the left gas channel 221 and the right gas channel 222 extend downward from the bottom plate of the outer ring gas channel 22 and protrude outward; the end of the left gas channel 221 and the right gas channel 222 is connected to the side wall plate of the upper air cavity 27, the front end of the main ejector pipe 24 and the gas guide pipe 25 intersects with the rear wall plate of the upper air cavity 27, and the main ejector pipe 24 is connected to the upper air cavity;

[0046] The head 12 of the furnace head 1 is provided with a transverse support plate 15, and a guide groove 151 is provided on the transverse support plate 15.

[0047] The upper end of the transverse support plate 15 is connected to the rear wall of the upper air cavity 27, and the main ejector tube 24 and the air guide tube 25 are respectively opposite to the guide groove 151; the nozzle of the air outlet 131 is opposite to the guide groove 151.

[0048] With this structure, the gas and air are mixed in the outer ring premixing chamber, and then enter the left gas channel and the right gas channel, and finally enter the front gas channel. Under the guidance of the left gas channel 221 and the right gas channel 222, the gas-air mixture in the outer ring gas channel 22 is evenly distributed.

[0049] As a further improvement of this utility model: the upper air cavity 27 is recessed at the connection point with the main injector tube 24 and the air guide tube 25 to form an air collecting cavity 28, which serves to gather compressed air so that the combustion gas and air can quickly enter the main injector tube.

[0050] The connection end of the outer ring premixing chamber 23 with the left gas channel 221 and the right gas channel 222 is provided with a first guide slope 231;

[0051] The connection ends of the left gas channel 221 and the right gas channel 221 with the bottom plate at the front of the outer ring gas channel are provided with a second guide slope 232; the first guide slope 231 and the second guide slope 232 are spiral-shaped to prevent the generation of eddies and to facilitate rapid gas distribution.

[0052] As a further improvement of this utility model: the head 12 is provided with a left support seat 121 and a right support seat 122, and the left support seat 121 and the right support seat 122 are respectively provided with pins;

[0053] The connecting plate 26 has fixed base plates 261 on both sides of the middle part, and the fixed base plates 261 have pin holes.

[0054] like Figure 2 As shown, the left support 121 and the right support 122 respectively support the fixed base plate 261, with pins and pin holes for insertion. This design ensures accurate positioning during assembly, using the nozzles of the main injector tube and the gas outlet seat 131 to be aligned; it also prevents the burner seat 2 from rotating relative to the furnace head.

[0055] As a further improvement of this utility model: an arc-shaped guide plate 224 is provided at the rear of the outer ring gas tank 22, and there is a gap between the arc-shaped guide plate 224 and the outer ring wall plate of the outer ring gas tank 22, and they are parallel. This design reduces the excessive pressure of the gas entering the outer ring gas tank from the outer premixing chamber in that part, which would cause the flame of the burner cap in that part to be too high, and diverts the gas in clockwise and counterclockwise directions.

[0056] As a further improvement of this utility model: the central angle of the outer arc-shaped guide plate 224 is smaller than the central angle of the outer ring premixing cavity 23.

[0057] As a further improvement of this utility model: the rear part of the fire distributor seat 2 is provided with a positioning seat 29, and the positioning seat 29 is provided with a positioning hole;

[0058] The burner head 1 is provided with a rear positioning post 123, and the rear positioning post 123 and the positioning hole are inserted into the head support positioning seat 29 of the burner head 1.

[0059] As a further improvement of this utility model: the two ends of the connecting plate 26 are provided with crescent-shaped portions 262, which are connected to the inner ring wall plate of the outer ring gas groove 22.

[0060] The burner head 1 has a liquid collection tank 16 surrounding the head 12 on the seat plate 11.

[0061] In use, the head 12 extends through the through hole in the liquid receiving tray, and the base plate supports the liquid receiving tray. A sealing ring can be placed in the liquid collection tank 16. The sealing ring cooperates with the liquid receiving tray support, providing sealing and cushioning functions.

[0062] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
