Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a high-temperature resistant liquid fuel burner. Background Technology

[0002] Liquid fuel burners are combustion devices that use liquid fuels such as methanol as energy. The burner head is usually made of low-cost and easy-to-process aluminum alloy, replacing the traditional cast iron burner head as the combustion appliance. However, because aluminum alloy has a low melting point, the burner head is easily eroded and deformed by high temperature during long-term contact with the high-temperature flame generated by the vaporization and combustion of liquid fuel, which is not conducive to its use and popularization.

[0003] Chinese utility model patent with announcement number CN201561426U discloses an aluminum alloy burner head for a gas stove, including a burner head ring and a heating tube disposed on the burner head ring, wherein the burner head ring is provided with a stainless steel heat insulation sheet riveted to it.

[0004] The problem with existing technology is that it uses rivets for fixing, involves many processing steps, and is not conducive to disassembly, assembly, and maintenance. Therefore, there is room for improvement in existing technology. Utility Model Content

[0008] The fireproof cover is made of steel or copper. The fireproof cover is an inverted conical ring. The outer circumference of the fireproof cover is provided with an edge, which overlaps the top of the cylindrical part.

[0009] As a further improvement to the above technical solution, the fireproof cover includes a conical part and a bottom ring. The conical part is wider at the top and narrower at the bottom. The edge is integrally formed on the outer periphery of the top of the conical part, and the bottom ring is integrally formed on the bottom of the conical part. The bottom ring is interference-fitted with the inner wall of the cylindrical part.

[0010] As a further improvement to the above technical solution, a curved groove is provided below the seat plate, a heating tube is inserted into the curved groove, and an air inlet pipe is connected to the heating tube.

[0012] As a further improvement to the above technical solution, a convex ring is provided inside the air distribution hole, and the height of the convex ring is higher than the surface of the seat plate and lower than the cylindrical part.

[0013] As a further improvement to the above technical solution, an ignition needle is installed on the seat plate, and a support foot is provided at the bottom of the seat plate.

[0014] The beneficial effects of this utility model are: by setting a fireproof cover made of steel or copper on the cylindrical part of the furnace head, the high-temperature flame is prevented from affecting the cylindrical part of the furnace head seat, and the cylindrical part is prevented from being burned and deformed.

[0024] Reference Figures 1 to 4 A high-temperature resistant liquid fuel burner includes a burner head seat 1, the burner head seat 1 includes a seat plate 11, the top of the seat plate 11 is provided with a cylindrical part 12, and a fireproof cover 2 is provided on the cylindrical part 12.

[0025] The fireproof cover 2 is made of steel or copper. The fireproof cover 2 is an inverted conical ring. The outer circumference of the fireproof cover 2 is provided with an edge 21, which overlaps the top of the cylindrical part 12.

[0026] A stainless steel fireproof cover 2 is placed over the cylindrical part 12, and the fireproof cover 2 is supported along the edge 21. This does not affect the heat transfer of the burner head seat 1, and also prevents the high-temperature flame from directly contacting the cylindrical part 12, which would cause the burner head seat 1 to be burned, deformed and damaged. It is resistant to high temperature and is easy and quick to disassemble and assemble.

[0027] Preferably, the fireproof cover 2 includes a conical portion 22 and a bottom ring 23. The conical portion 22 is wider at the top and narrower at the bottom. The edge 21 is integrally formed on the outer periphery of the top of the conical portion 22. The bottom ring 23 is integrally formed on the bottom of the conical portion 22. The bottom ring 23 is interference-fitted with the inner wall of the cylindrical portion 12.

[0028] The bottom ring 23 is used to position and install the fireproof cover 2 and to fix the bottom of the fireproof cover 2. The edge 21 overlaps the top edge of the cylindrical part 12 to support the fireproof cover 2 and prevent the fireproof cover 2 from rotating and loosening.

[0029] Preferably, a curved groove 13 is provided below the seat plate 11, and a heating tube 3 is inserted through the curved groove 13. An air inlet pipe 31 is connected to the heating tube 3.

[0030] The center of the base plate 11 is provided with an inner flame cover seat 14, and a nozzle 141 is screwed onto the inner flame cover seat 14. The nozzle 141 is connected to the air inlet pipe 31, and an inner flame cover 5 is installed on the nozzle. The base plate 11 is provided with a ring array of uniform air holes 111.

[0031] After the heating tube 3 heats and vaporizes the liquid fuel, the gaseous fuel is sprayed through the air inlet pipe 31 to the nozzle 141 and then sprayed out from the inner burner cover 14. After mixing with air, it is ignited and burned. Air enters from the bottom of the base plate 11, and after passing through the array of uniform air holes 111, it becomes a vertical straight stream, mixes with the fuel and burns, so that the burner firepower is uniform.

[0032] Preferably, a raised ring 15 is provided inside the air distribution hole 111. The height of the raised ring 15 is higher than the surface of the seat plate 11 and lower than the cylindrical part 12. The raised ring 15 is provided to prevent juice or food from entering the air distribution hole 111 and causing blockage, which would affect the combustion effect.

[0033] An ignition needle 4 is installed on the base plate 11, and a support foot 16 is provided at the bottom of the base plate 11. The support foot 16 is used to support the burner head seat 1, so that a cavity is formed at the bottom of the burner head seat 1, which is conducive to air intake.

[0034] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
