[0052] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0053] like Figure 1 , 2 As shown, this embodiment provides a single-burner stove, which includes only one burner head, making the overall structure more compact. Specifically, the single-burner stove includes a burner 1 and a corresponding valve assembly, wherein the injector tube of the burner 1 extends toward the valve assembly. The valve assembly includes a direct-insertion valve 2, including a valve tube and a nozzle disposed on the valve tube. The valve tube extends toward the injector tube, and the nozzle is inserted into the injector tube. The valve tube of the direct-insertion valve 2 directly extends into the injector tube to complete the connection, without the need for additional connecting structures such as copper pipes. The valve tube of the direct-insertion valve 2 and the injector tube of the burner 1 are arranged opposite each other and extend so that they are on the same extension line.

[0054] This single-burner stove uses a burner 1 and a direct-insertion valve 2. The direct-insertion valve 2 is directly connected to the injector tube of the burner 1, eliminating the need for additional copper pipes or other connecting structures. This results in fewer internal structural components and a smaller size of the components, reducing costs while allowing for greater spacing between components and easier component layout.

[0055] like Figure 4 , Figure 5 As shown, the air inlet 23 of the single-burner stove is located on the direct-insertion valve 2. The air inlet 23 is directly connected to the direct-insertion valve 2 from the outside of the single-burner stove, and is directly connected to the injector tube of the burner 1 through the direct-insertion valve 2, which further simplifies the air intake structure by omitting the connecting structure such as copper pipes.

[0056] The single eye zone saves the air inlet pipe, and the air inlet 23 is directly arranged on the straight insertion valve 2, the air inlet route is simple, the pressure loss is small, and the straight insertion valve 2 directly realizes the function of the air inlet pipe, and the straight insertion valve 2 is directly installed on the chassis.

[0057] As shown in Figure 4 , Figure 5 and Figure 6 , the straight insertion valve 2 further comprises an electromagnetic valve 24, and the air inlet 23 is arranged in the valve cavity of the electromagnetic valve 24. The bottom of the straight insertion valve 2 is the electromagnetic valve 24, which is used to control the opening and closing of the air inlet pipe, and the air inlet 23 is directly communicated from the bottom of the single eye zone to the valve cavity of the electromagnetic valve 24, so that the entire straight insertion valve 2 bears the function of the air inlet valve. The air inlet route is simple, the pressure loss is small, and the function of the air inlet pipe is directly realized through the valve cavity of the electromagnetic valve 24.

[0058] As shown in Figure 3 , Figure 5 , the ejector pipe comprises an inner ring ejector pipe 11 and an outer ring ejector pipe 12, and the straight insertion valve 2 comprises corresponding inner ring valve pipe 21 and outer ring valve pipe 22, wherein the inner ring ejector pipe 11 and the inner ring valve pipe 21 are tightly matched. Specifically, the inner ring valve pipe 21 is tightly matched with the inner ring ejector pipe 11 through the inner ring nozzle 211, the inner ring ejector pipe 11 has an internal thread, the outer end of the inner ring nozzle 211 has an external thread, and the two are screwed together to complete the fixing, and the inner ring nozzle 211 is provided with an air injection hole communicated with the outside for supplementing primary air.

[0059] The outer ring ejector pipe 12 and the outer ring valve pipe 22 are gap matched. Specifically, the outer ring valve pipe 22 comprises an outer ring nozzle 221, and the outer ring nozzle 221 is gap matched with the outer ring ejector pipe 12 without being fixed, so that after the inner ring valve pipe 21 is fixed with the inner ring ejector pipe 11, the outer ring valve pipe 22 still has assembly allowance with the outer ring ejector pipe 12, which can provide fault tolerance for some assembly errors. The outer ring nozzle 221 is provided with a spring 223, which is compressed to provide some restoring force to make the connection more stable after assembly is completed.

[0060] The inner ring ejector pipe 11 and the outer ring ejector pipe 12 are separately arranged, and loose / tight fitting is adopted to meet the different needs of the inner and outer rings. Among them, the inner ring fire cover has higher requirements for primary air, so the inner ring ejector pipe 11 and the inner ring valve pipe 21 are tightly matched. The outer ring fire cover has lower requirements for primary air, so gap fitting is adopted.

[0061] In this embodiment, the gap between the outer ring ejector pipe 12 and the outer ring valve pipe 22 is preferably 0.5 mm. The gap between the outer ring ejector pipe 12 and the outer ring valve pipe 22 is 0.5 mm, which makes the assembly easier and the connection effect better.

[0062] In other embodiments, other specific numerical values can also be preferred according to the structural differences.

[0063] As shown in Figure 5 , Figure 7 , the inner ring nozzle 211 of the inner ring valve pipe 21 includes an inner ring nozzle hole 212, which is arranged at the inlet end of the inner ring nozzle 211, and the aperture of the inner ring nozzle hole 212 is smaller than the aperture of the outlet end of the inner ring nozzle 211.

[0064] The inner cavity of the inner ring nozzle 211 is in the shape of an hourglass, the apertures of both ends are wide, and the middle is narrow to form the inner ring nozzle hole 212. When the gas enters the inner ring nozzle 211, it will first pass through the inner ring nozzle hole 212. At this time, the gas speed will increase due to the contraction of the aperture, and the inner ring nozzle hole 212 is arranged close to the air inlet hole, so that the increased gas speed can drive the external air introduced by the air inlet hole, thereby improving the primary air intake effect. After passing through the inner ring nozzle hole 212 and introducing the primary air inlet, the gas speed will decrease due to the increase of the aperture, so that the gas entering the ejector pipe is more stable.

[0065] The inner ring valve pipe 21 adopts a close fit, the outlet end position is fixed, and there is no eccentricity problem. Arranging the nozzle hole at the inlet end can slow down the jet flow speed and mix with the air, so that the air intake is more stable.

[0066] As shown in Figure 5 , Figure 7 , the outer ring nozzle 221 of the outer ring valve pipe 22 includes an outer ring nozzle hole 222, which is arranged at the inlet end of the outer ring nozzle 221, and the aperture of the outer ring nozzle hole 222 is smaller than the aperture of the inlet end of the outer ring nozzle 221.

[0067] The inner cavity of the outer ring nozzle 221 is in the shape of a needle, the aperture at the inlet is large and constant, and the aperture suddenly decreases to form the outer ring nozzle hole 222 to the outlet. This structure can increase the gas passing area at the outlet and improve the gas speed. The reduction of the area can dilute the eccentricity problem caused by the gap assembly.

[0068] The outer ring valve pipe 22 adopts a gap fit, and the outlet end position has a certain activity space, so there may be an eccentricity problem. Arranging the nozzle hole at the outlet end can reduce the jet area and reduce the eccentricity problem.

[0069] As shown in Figure 4 , the straight insertion valve 2 includes an elastic pad 25, and the straight insertion valve 2 adjusts the gap of the outer ring nozzle pipe through the elastic pad 25. In this embodiment, the elastic pad 25 is specifically a rubber pad, which has a certain deformation ability, so that after the inner ring valve pipe 21 of the straight insertion valve 2 and the inner ring ejector pipe 11 of the combustor 1 are fixedly connected, the elastic deformation of the elastic pad 25 can compensate for the assembly errors when there are assembly errors, so that the outer ring valve pipe 22 can be correctly connected to the outer ring ejector pipe 12. The elastic pad 25 is arranged at the bottom of the straight insertion valve 2, and is used to adjust the installation allowance of the straight insertion valve 2 up and down and left and right.

[0070] In other embodiments, other structures can also be used to achieve the above functions, such as by setting some structures with adjustable installation positions on the direct insertion valve 2.

[0071] like Figure 4 As shown, the air inlet 23 is located at the bottom of the direct-insertion valve 2. The air intake route is simple, the pressure loss is small, and the direct-insertion valve 2 directly realizes the function of the air intake pipe, which can be directly installed on the chassis.

[0072] In other embodiments, depending on the environment, the air inlet 23 can be set on the side of the stove or in other locations to achieve easy installation of a single-burner stove, as long as the external fuel is directly connected to the inside of the direct-insertion valve 2.

[0073] like Figure 2 As shown, the valve assembly and burner 1 are arranged along the length of the single-burner stove. This structural layout is more spatially efficient, allowing the burner 1 and the direct-insertion valve 2 to be positioned on both sides inside the stove, resulting in higher space utilization. The structure is more compact, with greater spacing between components.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
