Description

Technical Field

[0001] This utility model belongs to the field of fuel furnace technology, specifically a windproof furnace. Background Technology

[0002] In recent years, with the popularization of outdoor adventure and camping activities, multi-fuel stoves have gradually become an important tool in wilderness survival equipment due to their strong fuel adaptability and portability. However, existing outdoor multi-fuel stoves still have significant technical bottlenecks in terms of combustion stability under complex weather conditions, especially in terms of combustion efficiency and safety under wind interference, which urgently need to be optimized.

[0003] Currently, most multi-fuel stoves on the market adopt an open or semi-closed combustion chamber structure, relying on natural convection for air supply and exhaust. This design can maintain normal combustion under windless or light wind conditions. However, in strong winds, the hot exhaust gases produced by combustion are forced back into the combustion zone. This phenomenon not only dilutes the oxygen content of the fresh air but also causes some of the oxygen required for the combustion reaction to be replaced by the exhaust gases (containing CO2, water vapor, etc.), resulting in insufficient oxygen supply to the flame root. At this time, the flame color changes from blue to yellow, thermal efficiency decreases significantly, and the number of incompletely burned carbon particles increases, producing black smoke. When the amount of backflowing exhaust gas exceeds the combustion chamber's capacity, localized oxygen deficiency will directly cause the flame to flicker or even extinguish. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies by providing a windproof stove. This windproof stove can effectively prevent hot exhaust gas from being forced back into the combustion zone, avoid the flame from turning yellow and producing black smoke due to insufficient oxygen supply at the flame root, and also prevent the flame from flickering or even going out due to lack of oxygen.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a windproof stove, comprising a support plate and a burner head, wherein the support plate is provided with an installation hole, a fuel supply port is provided in the installation hole, a plurality of air supply holes are provided on the support plate around the installation hole, the burner head is provided on the installation hole, the burner head includes an air supply pipe communicating with the fuel supply port and a combustion chamber located at the top of the air supply pipe, a plurality of flame overflow holes are provided on the combustion chamber, a windproof cover covering the plurality of air supply holes is provided on the outer wall of the air supply pipe, and a through hole is provided on the air supply pipe inside the windproof cover. When this type of windproof stove is burning, air enters the windproof cover through the air supply hole on the support plate, and then enters the air supply pipe through the through hole to mix with the fuel. Due to the obstruction of the windproof cover and the support plate, the air participating in the combustion is forced to enter from below the air supply hole, which effectively prevents hot exhaust gas from being forced back into the combustion area. This avoids the flame from turning yellow and producing black smoke due to insufficient oxygen supply at the base of the flame, and also avoids the flame from flickering or even going out due to lack of oxygen.

[0006] In the above technical solution, preferably, the fuel supply port is connected to a fuel storage container via a pipe.

[0007] In the above technical solution, preferably, a fuel supply head is inserted into the bottom of the mounting hole, the fuel supply head is provided with the fuel supply port, and the fuel supply head is threadedly connected to the gas supply pipe. This structure facilitates the assembly and replacement of the fuel supply head and the burner head, and is suitable for the rapid replacement and assembly of different fuel supply heads and burners.

[0008] In the above technical solution, preferably, the support plate is provided with a recess, and the mounting hole and several gas supply holes are all located within the recess. Placing the mounting hole within the recess allows the burner head to be lowered, thereby reducing wind interference with the flame.

[0009] In the above technical solution, preferably, the windproof furnace includes a support frame with a recessed groove in the middle, and the bottom of the recessed groove of the support frame is provided with an installation port, on which the support plate is fixed. This structure allows the sidewalls of the recessed groove to block wind interference.

[0010] In the above technical solution, preferably, the sink trough has inclined surfaces on opposite sides, and a plurality of positioning holes are provided on the inclined surfaces near the top, with a cookware rack mounted on the positioning holes. This structure allows cookware to be placed on the cookware rack, and the cookware rack is easy to assemble and disassemble.

[0011] In the above technical solution, preferably, the end of the cookware rack is bent downward and inserted into the positioning hole. This structure can more stably fix the cookware rack.

[0012] Compared with the prior art, this utility model has the following beneficial effects: When this windproof stove is burning, air enters the windproof cover from the air supply hole on the support plate, and then enters the air supply pipe from the through hole to mix with the fuel. Due to the obstruction of the windproof cover and the support plate, the air participating in the combustion is forced to enter from below the air supply hole, which effectively avoids the hot exhaust gas being forced into the combustion area in reverse, thereby avoiding the flame color turning yellow and producing black smoke due to insufficient oxygen supply at the flame root, and at the same time avoiding the flame flickering or even going out due to lack of oxygen.

The burner head 2 includes an air supply pipe 6 communicating with the fuel supply port 5 and a combustion chamber 7 located at the top of the air supply pipe 6. The combustion chamber 7 is provided with a plurality of flame overflow holes 71. A windproof cover 8 covering the plurality of air supply holes 4 is provided on the outer wall of the air supply pipe 6. A through hole 9 is provided on the air supply pipe 6 inside the windproof cover 8. When this type of windproof stove is burning, air enters the windproof cover 8 through the air supply hole 4 on the support plate, and then enters the air supply pipe 6 through the through hole 9 to mix with the fuel. Due to the obstruction of the windproof cover 8 and the support plate 1, the air participating in the combustion is forced to enter from below the air supply hole 4, which effectively prevents hot exhaust gas from being forced back into the combustion area, thereby avoiding the flame color turning yellow and producing black smoke due to insufficient oxygen supply at the flame root, and at the same time avoiding the flame flickering or even going out due to lack of oxygen.

[0018] In this embodiment, the fuel supply port 5 is connected to a fuel storage container (not shown in the figure) via a pipe.

[0023] In this embodiment, the end of the cookware rack 17 is bent downward and inserted into the positioning hole 16. This structure can more stably fix the cookware rack 17.

[0024] When using this type of windproof stove, the support frame 13 is hung on an outdoor table with the bottom of the support frame 13 off the ground. Air can enter the windproof cover 8 from below the air supply hole 4, and then enter the air supply pipe 6 through the through hole 9 to mix with the fuel. Due to the obstruction of the windproof cover 8 and the support plate 1, the air participating in the combustion is forced to enter from below the air supply hole 4, which effectively prevents hot exhaust gas from being forced back into the combustion area, thereby avoiding the flame from turning yellow and producing black smoke due to insufficient oxygen supply at the base of the flame, and also preventing the flame from flickering or even going out due to lack of oxygen.
