[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0026] As Figures 1 to 7 shown, the utility model is a kind of combustor with reasonable structure and low cost, mainly by three parts, respectively, is fire cover (1), fire cover seat (2) and combustor base (3), the fire cover seat (2) is engaged and arranged above combustor base (3), and the fire cover (1) is covered on the top of fire cover seat (2).

[0027] Among them, the combustor base (3) is integrally cast into shape, which is formed with auxiliary hole position (30) and gas passage (31), wherein the two ends of the gas passage (31) are gas input port (310) and gas output port (311) connected with gas passage respectively, the gas output port (311) is opposite to the injector pipe (20) of fire cover seat (2), and nozzle (312) is arranged and installed therein. And the auxiliary hole position (30) is the positioning assembly for auxiliary ignition needle (313) and thermocouple (314), to cooperate with ignition and sensing work. It can be noted that the combustor base (3) is designed with sunken conical sink cavity (315) for embedding the injector pipe (20) on the fire cover seat (2) to position and set, because the injector pipe (20) is cylindrical structure, which can be well fitted with the conical sink cavity (315), and the conical sink cavity (315) with sunken design can be based on the self-weight of fire cover seat (2) to realize positioning installation, avoid the use of shaking displacement, ensure its stability.

[0028] Regarding the fire cover seat (2), it mainly has two design focuses, namely the injection pipe (20) and the gas distribution block (21). The injection pipe (20) is formed at an angle ranging from 1° to 90° based on the cross-sectional plane. Such design can extend the length of the injection pipe (20) without changing the height and lateral size of the burner, thereby enhancing the injection capacity of the injection pipe, making the gas and air mix more fully in the injection pipe (20), and making the gas burn more fully and the carbon monoxide content lower, thereby effectively improving the thermal efficiency of the burner and facilitating the application of the burner to high-power burners. Moreover, the injection pipe (20) at a proper inclination angle can not only facilitate the miniaturization of the burner but also reduce the manufacturing difficulty and production cost of the burner. It is worth mentioning that the burner base (3) is integrally formed by casting, and the injection pipe (20) is formed by drilling, boring or drawing. Such method can reduce the production cost to a certain extent. The gas distribution block (21) is designed in the gas outlet direction of the injection pipe (20) and is formed in an arc shape. The gas distribution block (21) can distribute the mixed gas emitted from the injection pipe (20) and make the mixed gas flow uniformly to both sides of the gas distribution block (21), so that each fire hole (22) emits fire uniformly and avoids the emitted gas from impacting the fire hole (22) in front of the injection pipe (20) when being emitted, thereby causing uneven flame.

[0029] In addition, the gas passage (31) is formed in a stepped concentric circle structure. Such design can pressurize the introduced gas to ensure that the gas emitted through the nozzle (312) has a certain flow rate to drive sufficient air into the injection pipe (20) for mixing.

[0030] The fire cover (1), the fire cover seat (2) and the burner base (3) are positioned and assembled through reasonable structural design, without the need for auxiliary fastening hardware fittings, thereby achieving convenient assembly and disassembly and stable use. Specifically, the burner base (3) further integrally has a plurality of positioning support blocks (32) on the top, at least one of which is designed with a groove (320) to assist the positioning and installation of the fire cover seat (2), and the conical sink cavity (315) is designed with a counterbore (3150), and the injection pipe (20) is formed with a positioning block (200) at the bottom. The fire cover seat (2) and the burner base (3) are further installed and reinforced by the cooperation of the counterbore (3150) and the positioning block (200).

[0031] It should be noted that the gas outlet (311) of the gas passage (31) is equipped with a nozzle (312), and the nozzle (312) needs to be aligned with the injection pipe (20). Therefore, the inclination angle of the gas outlet (311) should correspond to the forming angle of the injection pipe (20) to ensure that the gas is accurately injected into the injection pipe (20) and to ensure gas safety.

[0032] The specific principle and steps in use are as follows:

[0033] The gas enters the gas passage (31) through the gas input port (310) on the burner seat (3), and is sprayed out through the nozzle (312). There is a space communicating with the atmosphere between the nozzle (312) and the ejector pipe (20). When the gas is sprayed out from the nozzle (312), the air will be brought into the ejector pipe (20). The subsequent gas and air will be fully mixed in the ejector pipe (20), so as to form the air-fuel mixture. The mixture is ignited by the ignition needle (313) and the electric thermocouple (314) and inducted by the flame, and then sprayed out from the fire hole (22).

[0034] The utility model discloses a structure is reasonable and simple, can ensure that gas burns fully, can also ensure that the combustion is even, reaches the cost reduction while realizing use firm, work stable.
