Description

Technical Field

[0001] This utility model relates to a stove, specifically an outdoor gas stove. Background Technology

[0002] Outdoor gas stoves are core equipment for modern outdoor activities, primarily serving the purposes of cooking, heating, and providing a heat source, especially indispensable in camping, picnics, and hiking. These essential outdoor cooking tools can quickly heat food or boil water, supporting various cooking methods such as frying, stir-frying, boiling, and stewing. Some models boast high heat output (e.g., 2.0KW), boiling 1 liter of water in just 3 minutes, significantly improving the efficiency of outdoor cooking. Gas combustion primarily produces carbon dioxide and water, releasing almost no harmful particulate matter or smoke, minimizing its impact on the natural environment (especially ecological reserves). Compared to charcoal or wood-burning stoves, it avoids air pollution and forest resource depletion caused by burning wood, aligning with sustainable outdoor principles. Portable and easy to use, adaptable to multiple scenarios, and lightweight designs (common portable gas stoves weigh only 800-1000 grams) with a folding structure for easy backpack carrying, one-button ignition after installing the gas canister eliminates the need for preheating or pressurization, providing a user experience similar to a household stove. Automatic gas shut-off protection ensures that if the flame is accidentally extinguished or the stove is tilted, a sensor immediately cuts off the gas supply to prevent gas leaks and fires.

[0003] Although many outdoor gas stoves now have windproof and anti-interference structures, and most products are equipped with windproof rings or flame stabilizing structures to ensure stable firepower in open-air environments and reduce the risk of flameout, they also cause heat to be too concentrated on the stove shell or stove plate. If it needs to be moved or adjusted slightly during use, it is easy to cause burns. A large amount of heat is transferred to the stove shell or stove plate, which is not conducive to heat concentration. At the same time, the stove shell and stove plate will overheat and be damaged if they are kept at high temperatures for a long time. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an outdoor gas stove.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: an outdoor gas stove, comprising a stove plate and multiple burners. The center of the stove plate is recessed downward to form a heat-insulating groove. A burner fixing plate is provided in the heat-insulating groove. The outer edge of the burner fixing plate extends outward and upward, and the outer edge of the burner fixing plate is higher than the surface of the stove plate. A heat-insulating gap is left between the lower surface and the bottom outer edge of the burner fixing plate and the heat-insulating groove. Multiple burners are evenly arranged and fixed on the bottom surface of the burner fixing plate. A metal air inlet pipe is fixedly connected to the bottom of each burner. The metal air inlet pipe penetrates the bottom surface of the heat-insulating groove and is connected to a gas control valve through a pipe. The other end of the gas control valve is provided with a gas connector for connecting to a gas tank. Each metal air inlet pipe on the upper and lower surfaces of the bottom surface of the heat-insulating groove is tightened with a fixing nut. Multiple pot support frames are evenly fixed on the surface of the stove plate around the heat-insulating groove. The top of the pot support frame is higher than each burner.

[0006] Furthermore, an ignition needle is also provided inside the burner head fixing plate. The ignition needle is located on one side of the burner head and is electrically connected to the igniter.

[0007] Furthermore, a box-shaped furnace shell is provided below the furnace plate, and the furnace plate covers and is fixed to the top of the furnace shell.

[0008] Furthermore, the upper end of the pot body support frame is rotatably connected to an outwardly flipping pot body extension bracket via a pivot, and the upper edge of the pot body extension bracket after it is opened outward is provided with a serrated anti-slip structure.

[0009] The bottom of the furnace shell is fixed with evenly arranged folding support legs.

[0010] Furthermore, a rotating bracket that can be rotated open in the horizontal plane is provided below the furnace plate, and a push-button igniter is fixed to the outer end of the rotating bracket.

[0011] Furthermore, the furnace plate, the burner head fixing plate, and the furnace shell are square structures. A burner head is set in the center of the burner head fixing plate, and four burners are evenly arranged around the center.

[0012] Furthermore, the furnace plate, the burner head fixing plate, and the furnace shell are all circular structures. There is a burner head in the center of the burner head fixing plate, and six burners are evenly arranged around the center.

[0013] Furthermore, the furnace plate, burner head fixing plate, furnace shell, and pot body support frame are made of stainless steel.

[0014] With the above design, the outer edge of the burner head fixing plate of this utility model extends outward and upward, and the outer edge of the burner head fixing plate is higher than the surface of the stove plate. This can better cover each burner head, play a good role in preventing wind and heat accumulation, effectively prevent the flame from being blown out by the wind, and better adapt to outdoor use. Moreover, the outer edge of the burner head fixing plate also forms a good heat accumulation effect, so that more of the heat generated by combustion is concentrated on the pot body above it, resulting in higher thermal efficiency. In addition, the burner head fixing plate has a blocking effect on the flame, which can prevent the flame from directly contacting the stove plate when the pot is placed down. This prevents the flame generated by the burner head from directly scorching the stove plate during use, preventing the stove plate from getting red and black. Therefore, even if the stove plate and the stove shell are used for a long time, they will not get hot, preventing burns when picking up the stove after use. In addition, there are heat-insulating gaps between the lower surface and bottom outer edge of the burner head fixing plate and the heat-insulating groove, so that the burner head fixing plate does not directly contact the furnace plate, but only indirectly through a few metal air inlet pipes. This reduces the contact area between the burner head fixing plate and the furnace plate, which can greatly reduce heat loss and reduce the direct transfer of heat to the furnace plate and furnace shell. This prevents heat from being lost outward through a larger area of ​​the furnace plate and furnace shell, thus resulting in higher heat utilization. Attached Figure Description

[0018] The following is a detailed description of this embodiment with reference to the accompanying drawings: This embodiment provides an outdoor gas stove; please refer to the accompanying drawings in the instruction manual. Figure 1-4 .

[0019] like Figure 1-4 As shown, an outdoor gas stove includes a furnace plate 1 and multiple burners 2. The center of the furnace plate 1 is recessed downward to form a heat-insulating groove 3. A burner fixing plate 4 is disposed within the heat-insulating groove 3. The outer edge of the burner fixing plate 4 extends outward and upward, and the outer edge of the burner fixing plate 4 is higher than the surface of the furnace plate 1. A heat-insulating gap is left between the lower surface and the bottom outer edge of the burner fixing plate 4 and the heat-insulating groove 3. Multiple burners 2 are evenly arranged and fixed on the bottom surface of the burner fixing plate 4. A metal air inlet pipe 6 is fixedly connected to the bottom of each burner 2. The metal air inlet pipe 6 penetrates the bottom surface of the heat-insulating groove 3 and is connected to the gas control... The valve is connected through a pipe, and the other end of the gas control valve is equipped with a gas connector for connecting to the gas tank. Each metal air inlet pipe 6 on the upper and lower surfaces of the bottom of the heat insulation groove 3 is tightened with a fixing nut 7. Multiple pot body support frames 8 are evenly fixed on the surface of the furnace plate 1 around the heat insulation groove 3. The top of the pot body support frame 8 is higher than each burner head 2, that is, the top of the burner head 2 is lower than the outer edge of the burner head fixing plate 4. The top of the pot body support frame 8 is higher than the outer edge of the burner head fixing plate 4. This ensures that when in use, there is a gap between the bottom of the pot body and the outer edge of the burner head fixing plate 4, which can both ensure air entry and prevent wind.

[0020] To facilitate the use of electronic ignition, such as in existing outdoor gas stoves, an ignition needle 9 is also provided inside the burner head fixing plate 4. The ignition needle 9 is located on one side of the burner head 2 and is electrically connected to the igniter 10.

[0021] To facilitate the support of the furnace plate 1 and its use, a box-shaped furnace shell 11 is provided below the furnace plate 1, and the furnace plate 1 is covered and fixed on the top of the furnace shell 11.

[0022] To facilitate support of a large pot body, the upper end of the pot body support frame 8 is rotatably connected to an outwardly folding pot body extension bracket 12 via a pivot. The upper edge of the pot body extension bracket 12 after it is opened outward is provided with a serrated anti-slip structure 13, similar to the folding pot body support structure used in existing outdoor gas stoves. To facilitate carrying the stove shell 11, the bottom is fixed with evenly arranged folding support legs 14.

[0023] To facilitate ignition via the igniter 10 when the rotating bracket 5 is opened, a rotating bracket 5 that can be rotated open in the horizontal plane is provided below the furnace plate 1, and a press-type igniter 10 is fixed to the outer end of the rotating bracket 5.

[0024] The furnace plate 1, the burner head fixing plate 4, and the furnace shell 11 are square structures. A burner head 2 is set in the center of the burner head fixing plate 4, and four burner heads 2 are evenly arranged around the center. Alternatively, they can be circular structures, i.e., the furnace plate 1, the burner head fixing plate 4, and the furnace shell 11 are circular structures, with a burner head 2 set in the center of the burner head fixing plate 4 and six burner heads 2 evenly arranged around the center. The furnace plate 1, the burner head fixing plate 4, the furnace shell 11, and the pot support frame 8 are made of stainless steel, which is not only fireproof and heat resistant, but also easy to process and cost-effective.

[0025] The working principle of this utility model is the same as that of existing gas stoves in terms of combustion and electronic ignition. The difference lies in the setting of the heat insulation groove 3 and the burner head fixing plate 4. The outer edge of the burner head fixing plate 4 extends outward and upward, and the outer edge of the burner head fixing plate 4 is higher than the surface of the stove plate 1. This can better cover each burner head 2, playing a good role in wind protection and heat concentration, effectively preventing the flame from being blown out by the wind, and making it more suitable for outdoor use. Moreover, the outer edge of the burner head fixing plate 4 also forms a good heat concentration effect, so that more of the heat generated by combustion is concentrated on the pot body above it. It is more efficient. In addition, there is a heat insulation gap between the lower surface and the bottom outer edge of the burner head fixing plate 4 and the heat insulation groove 3, so that the burner head fixing plate 4 does not directly contact the furnace plate 1, but only indirectly through several metal air inlet pipes 6. This reduces the contact area between the burner head fixing plate 4 and the furnace plate 1, which can greatly reduce heat loss and reduce the direct transfer of heat to the furnace plate 1 and the furnace shell 11. Therefore, even if the furnace plate 1 and the furnace shell 11 are used for a long time, they will not get hot, indicating that the heat is not dissipated to the outside through the larger area of ​​the furnace plate 1 and the furnace shell 11, so the heat utilization is higher.

[0026] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
