DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0026] Please see attached Figure 1 To Attachment Figure 3 The present embodiment provides a stove head, comprising an upper shell 1, a lower shell 2, an air guide 3 and an air guide pipe 4. The upper shell 1 comprises an upper ring plate 11, an inner plate 12 extending downward along the inner side of the upper ring plate 11, and an outer plate 13 extending downward along the outer side of the upper ring plate 11, wherein the extension length of the inner plate 12 is less than the extension length of the outer plate 13; the lower shell 2 is fixedly connected to the outer plate 13, and an air through hole 21 and a conduit through hole 22 are provided on the lower shell 2; the air guide 3 is arranged between the upper shell 1 and the lower shell 2, and comprises a bottom plate 31, an air guide plate 32 extending upward along the circumference of the bottom plate 31, and an air guide protrusion 33 extending upward along the middle part of the bottom plate 31; the bottom plate 31 and the outer plate 13 are fixedly connected to the lower shell 2, and an air through hole 21 and a conduit through hole 22 are provided on the lower shell 2; the air guide 3 is arranged between the upper shell 1 and the lower shell 2, and comprises a bottom plate 31, an air guide plate 32 extending upward along the circumference of the bottom plate 31, and an air guide protrusion 33 extending upward along the middle part of the bottom plate 31; the bottom plate 31 and the An air intake channel 51 is formed between the lower shell 2, an air guide channel 52 connected to the air intake channel 51 is formed between the air guide plate 32 and the outer plate 13, a gas mixing channel 53 connected to the air guide channel 52 is formed between the air guide plate 32 and the inner plate 12, and a gas outlet channel 54 connected to the gas mixing channel 53 is formed between the air guide protrusion 33 and the inner plate 12; the air guide pipe 4 passes through the duct through hole 22 and one end is surrounded and arranged between the inner plate 12 and the air guide plate 32, and a plurality of air outlet holes 41 are provided on the air guide pipe 4 on the side facing the gas mixing channel 53.

[0027] In the burner provided in this embodiment, air enters from the air through hole 21 of the lower shell 2, passes through the air intake channel 51 and the air guide channel 52, and is mixed with the fuel gas discharged from the gas outlet 41 of the gas guide pipe 4 in the gas mixing channel 53. The mixed gas is discharged through the gas outlet channel 54 for ignition and combustion. In this process, the fuel gas and air are fully mixed and then output for ignition and combustion, which can achieve full combustion and is beneficial to reducing energy consumption and usage costs.

[0028] Furthermore, a plurality of guide support plates 23 are provided on one end of the lower shell 2 facing the upper shell 1, and one end of the plurality of guide support plates 21 is connected to the air through hole 21, and the other end extends away from the air through hole 21. On the one hand, the guide support plates 21 provide support for the air guide member 3, so that the air guide member 3 is stably installed between the upper shell 1 and the lower shell 2. On the other hand, the guide support plates 21 can evenly separate the air entering from the air through hole 21, and evenly guide the air from the air intake channel 51 to the air guide channel 52, which is conducive to making the air and gas mix more evenly, thereby making the gas burn more fully, improving the combustion efficiency, and reducing energy consumption and use costs.

[0029] Furthermore, the air through hole 21 is provided in the middle of the lower shell 2, and a plurality of the guide support plates 23 are evenly arranged at intervals along the circumference of the air through hole 21. Air enters from the air through hole 21 in the middle, and enters the air guide channel 52 along the air intake channel 51 under the guidance of the evenly arranged guide support plates 23, which is conducive to more even mixing of air and gas and more complete combustion of gas.

[0030] Preferably, one end of the air guide pipe 4 is arranged around the upper part of the inner plate 12 and is located at the intersection of the air guide channel 52 and the gas mixing channel 53. When the air enters the gas mixing channel 53 from the air guide channel 52, it can meet and mix with the gas guided out from the gas outlet 41 of the air guide pipe 4 at the intersection of the air guide channel 52 and the gas mixing channel 53, which is beneficial to increase the mixing stroke of air and gas and make the air and gas mix more evenly.

[0031] Preferably, a chamfer is provided at the connection between the bottom plate 31 and the air guide plate 32. On the one hand, the chamfer can reduce flow resistance. A right-angle transition will produce a sharp change in the direction of the airflow, which may cause gas flow obstruction, increase resistance in the pipeline, and reduce gas delivery efficiency. The chamfered transition reduces the resistance to gas flow through a smooth transition, allowing the gas to pass through the transition more smoothly. On the other hand, the chamfer can reduce noise. The gas flow at the right-angle transition is prone to generate vortices and vibrations, which may cause noise and vibration. The chamfered transition can reduce the noise and vibration generated by the gas flow due to its smooth design.

[0032] Preferably, the diameter of the air guide plate 32 in this embodiment gradually increases from top to bottom, which is beneficial to gradually increase the diameter of the air guide channel 52 from its air inlet end to the air outlet end, so as to reduce the gas flow rate, thereby reducing the pressure drop caused by high-speed flow, which is beneficial to maintaining the overall efficiency of the system.

[0033] Preferably, the diameter of the inner plate 12 in this embodiment gradually decreases from top to bottom, which is beneficial to gradually increase the diameter of the gas mixing channel 53 from its gas inlet end to its gas outlet end, so as to reduce the gas flow rate, thereby reducing the pressure drop caused by high-speed flow, which is beneficial to maintaining the overall efficiency of the system, and at the same time, allowing air and gas to have more time and space to mix, so that the air and gas are mixed more evenly.

[0034] Preferably, the gas guide protrusion 33 of this embodiment is in a truncated cone shape, which is conducive to gradually increasing the diameter of the gas outlet channel 54 from its gas inlet end to the gas outlet end, reducing the gas flow rate, thereby reducing the pressure drop caused by high-speed flow, and is conducive to maintaining the overall efficiency of the system.
