Description

Technical Field

[0001] This utility model relates to the field of outdoor products technology, and in particular to a multi-fuel portable cone-shaped outdoor cooking device. Background Technology

[0002] Backpacking, hiking, and camping are among the most popular outdoor activities. These activities offer spectacular scenery, fresh air, and more. Participants often need to travel for several days, including one or more nights outdoors, requiring them to carry heavy equipment such as tents, sleeping bags, food, and cooking gear. Reducing equipment weight to improve comfort during outdoor activities is increasingly important. The use of alcohol stoves as portable outdoor cooking appliances is widely known in current technology. These stoves are used by mountain explorers, campers, backpackers, and others who need to boil water or cook hot meals in remote or primitive conditions. Compared to gas stoves, alcohol stoves are used in many parts of the world because alcohol is cheaper, easier to purchase, and harmless. However, their popularity is limited in China, mainly due to their poor overall performance. Even under ideal conditions, the heat output of these stoves is limited, let alone in actual outdoor wind and weather conditions, making it impossible to cook a meal. Among known alcohol stove technologies, overall performance is inefficient and wasteful of heat.

[0003] Cooking stoves are crucial for outdoor activities. Outdoor cooking devices primarily utilize fuel or energy converted into heat to cook, and different types of devices have different uses. Gas-fired devices, such as portable gas stoves and gas grills, use liquefied petroleum gas, butane, or other combustible gases mixed with air in a burner to produce a high-temperature flame that directly heats the cookware. Electric devices, like outdoor electric grills and electric cookers, are powered by an external power source or a built-in battery. The current passes through heating elements such as resistance wires, converting electrical energy into heat to heat the food. Solar-powered devices rely on solar panels to absorb sunlight and convert it into electricity or directly use the principle of concentrating light energy to convert it into heat for cooking. Charcoal-fired devices, such as charcoal grills, use the combustion of fuels like wood and charcoal to release a large amount of heat, cooking food through open flames or heat radiation.

[0004] However, some existing outdoor cooking devices suffer from problems such as incompatibility with various fuels, unstable combustion, and low fuel efficiency. On one hand, limited by their single fuel compatibility structure, many devices only support specific types of fuels. For example, traditional portable gas stoves only support standard gas canisters, and wood-burning stoves only support specific sizes of firewood. Once the specific fuel is exhausted or unavailable, cooking becomes difficult to continue. On the other hand, some devices claiming to be compatible with multiple fuels present difficulties in fuel conversion during actual use. Their structural design does not fully consider the combustion characteristics of different fuels, leading to complex adjustment procedures when changing fuels, and even safety hazards such as incomplete combustion and unstable flames due to fuel incompatibility. Furthermore, these devices often lack compatibility with new environmentally friendly fuels. In the current climate of promoting green outdoor practices, they fail to meet users' demands for clean energy, greatly limiting the applicability and practicality of outdoor cooking devices in different scenarios. Therefore, a portable cone-shaped outdoor cooking device is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable cone-shaped outdoor cooking device, which aims to improve the problems of existing outdoor cooking devices being unable to adapt to various fuels, having unstable combustion, and low combustion efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a portable conical outdoor cooking device, comprising a double-layer conical plate one, wherein the double-layer conical plate one includes a double-layer conical plate two, and two support rods one are fixedly connected to the inner wall of the top of the double-layer conical plate two, wherein a pot body one is fixedly connected to the top of the two support rods one, and a top cover one is fixedly connected to the top of the pot body one.

[0007] As a further description of the above technical solution: it includes a single-layer conical plate, the top of which is fixedly connected to two support rods, the top of which is fixedly connected to a pot body, the top of which is fixedly connected to a top cover, and an alcohol furnace is provided inside the double-layer conical plate and the single-layer conical plate.

[0008] As a further description of the above technical solution: the outer bottom end of the second pot body is in contact with the inner top wall of the single-layer conical plate, and the outer top end of the second pot body is in contact with the top end of the single-layer conical plate.

[0009] As a further description of the above technical solution: the outer bottom end of the first pot body is in contact with the inner top wall of the second double-layer conical plate, and the outer top end of the first pot body is in contact with the top end of the second double-layer conical plate.

[0010] This utility model has the following beneficial effects:

[0011] 1. In this utility model, a cone is formed by winding two double-layer conical plates (one and two). The cone is made of aluminum alloy, titanium alloy, or stainless steel, possessing good toughness and high-temperature resistance. After being assembled by fasteners, the cone shape provides significant load-bearing capacity to support the cookware. The internal combustion chamber formed by the two double-layer conical plates supports not only the alcohol stove but also alcohol blocks, alcohol cotton, charcoal, firewood, and other fuels, achieving multi-fuel compatibility. The main body consists of two double-layer conical plates (one and two) and a single-layer conical plate. To accommodate disassembly and storage in pot body one and two, and considering the different pot shapes (tall / slender and wide / short), the design includes both two-layer and single-layer structures. A two-layer structure is preferred for tall / slender pots, while a single-layer structure is preferred for wide / short pots. Support rods are available in both single and double layers. The key factor in deciding whether to use support rods is whether you are using fuel other than an alcohol stove. If so, support rods are needed to secure both pot body one and pot body two, increasing the combustion space within the cone shape and making it easier to add larger fuels such as firewood. The bracket formed by the two support rods provides stable support for pot body two, thus enabling the outdoor cooking device to adapt to different fuels and offering versatility in size selection, improving ease of use and the outdoor experience.

[0012] 2. In this utility model, by rolling up the first double-layer conical plate, the second double-layer conical plate, and the single-layer conical plate to reduce their volume, they can be placed inside the first pot body and the second pot body respectively, thereby achieving the convenience of carrying the outdoor cooking device and improving the customer experience.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 , Figure 5This utility model provides an embodiment of a portable cone-shaped outdoor cooking device, comprising a double-layer cone plate 1. When needed, the user can interlock the two ends to form a cone shape, with the two metal alloy plates forming a stable cone-shaped support surface. When stored, the double-layer plates can be rolled inward, significantly reducing the device's volume. The double-layer cone plate 1 includes a second double-layer cone plate 2, which is an integrated nested structure with the double-layer cone plate 1, and the two are matched with each other through precise slots. Two support rods 3 are fixedly connected to the inner wall of the top of the double-layer conical plate 2. Holes are provided at the top of the double-layer conical plate 2, allowing the support rods 3 to pass through and form a stable support structure with the double-layer conical plate 2. When the pot body 4 is placed on it, the support rods 3 evenly distribute the weight of the pot body onto the double-layer conical plate 2, while simultaneously increasing the volume of the internal combustion space of the cone. This increases the capacity to accommodate other fuels besides the alcohol stove 10, such as firewood and charcoal, and prevents excessive localized stress. The pot body 4 is fixedly connected to the top of the two support rods 3, and a top cover 5 is fixedly connected to the top of the pot body 4. When the top cover 5 is placed on the pot body 4, it can effectively prevent steam from escaping from the pot, forming a relatively enclosed cooking space. The bottom of the pot body 4 is fixedly connected to the inner wall of the top of the double-layer conical plate 2, which prevents the pot body 4 from shaking or shifting during cooking. At the same time, the double-layer conical plate 2 can better support and protect the pot body 4, extend the service life of the device, and ensure the smooth progress of outdoor cooking activities.

[0027] The top of the pot body 4 is externally fixedly connected to the top of the double-layer conical plate 2. When the support rod 3 is removed, the pot body 4 can be locked onto the top of the double-layer conical plate 2, allowing cooking with the alcohol stove 10. Compared with existing technologies, the outer shell of this alcohol stove 10 is made of aluminum alloy or titanium alloy, and the internal fuel evaporator is made of high-density, high-temperature resistant pure zirconium oxide fiber cotton and aluminum silicate fiber cotton, etc. This structure of the alcohol stove 10 is lightweight, simple in structure, and not easily damaged. Through the evaporator made of high-density materials, the large area of ​​liquid alcohol is dispersed into smaller units, improving the vaporization efficiency and making it easier to ignite, solving the problem of the alcohol stove 10 being difficult or unable to ignite at low temperatures. The high-density material fully adsorbs and fixes the liquid alcohol, further stabilizing the vaporization rate and preventing excessive vaporization due to wind. Combined with the multi-fuel combustion chamber of the conical plate, it greatly improves the combustion stability, easily handling various outdoor environments. At the same time, because it can fully absorb and fix the alcohol liquid, the burning alcohol liquid will not spill everywhere when the alcohol stove 10 is tipped over, thus preventing the danger of use. In addition, compared with conventional liquid alcohol stoves 10, which are not easy to extinguish after being lit, the alcohol stove 10 with this structure can be blown out, thereby better controlling the fire source.

[0028] Reference Figure 3 , Figure 4 , Figure 6This utility model provides an embodiment comprising a single-layer conical plate 6, which is formed by bending and rolling the single-layer conical plate 6 into a cone shape. This is a core component of the cooking device, providing support. Two support rods 7 are fixedly connected to the top of the single-layer conical plate 6. When using solid fuels such as wood or charcoal, the support rods 7 raise the pot body 8, increasing the internal combustion space volume of the cone. The pot body 8 is fixedly connected to the top of the two support rods 7. The pot body 8 can be used for cooking food and can conveniently store the single-layer conical plate 6 when moved. A top cover 9 is fixedly connected to the top of the pot body 8. During cooking, this protects against dust and other contaminants from entering the pot body 8, and during movement, it provides a sealing effect, preventing contents from spilling out.

[0029] The bottom of the second pot body 8 is fixedly connected to the inner wall of the top of the single-layer conical plate 6. The single-layer conical plate 6 effectively fixes the second pot body 8 to prevent displacement and tilting. When the second support rod 7 is removed, the second pot body 8 can be locked at the top of the single-layer conical plate 6, and the alcohol stove 10 can be used for cooking. The top of the second pot body 8 is fixedly connected to the top of the single-layer conical plate 6. The alcohol stove 10 is installed inside the single-layer conical plate 6 and inside the double-layer conical plate 1. The alcohol stove 10 is selected according to the needs of use. If the fuel is solid alcohol, firewood, or charcoal, the two support rods 1 3 and the second support rod 7 need to be passed through the top of the double-layer conical plate 2 and the single-layer conical plate 6 for use, and the built-in alcohol stove 10 is not required. If the alcohol stove 10 needs to be used directly, the built-in alcohol stove 10 is selected, and the support rods 1 3 and the second support rod 7 are pulled out.

[0030] Reference Figure 7 , Figure 8 , Figure 9 This utility model provides an embodiment where the double-layer conical plate 2, double-layer conical plate 1, and single-layer conical plate 6 are made of titanium alloy, aluminum alloy, or stainless steel, possessing good toughness and high-temperature resistance. After being assembled using tenons, slots, or buckles, the resulting cone shape provides significant load-bearing capacity to support the cookware. The double-layer conical plate 2, double-layer conical plate 1, and single-layer conical plate 6 themselves function as a heat-collecting plate, windbreak plate, and pot support, integrating these three elements into one unit, improving ease of use. Depending on the pot shape, the structure is divided into single-layer and double-layer structures. Compared to a common cylindrical shape, the cone shape increases the base area, enhancing stability during use and preventing tipping due to uneven outdoor ground. Furthermore, the cone shape provides a more efficient and larger combustion space, ensuring thorough mixing of combustibles and air.

[0031] The number and arrangement of vents in the double-layer conical plate 2, double-layer conical plate 1, and single-layer conical plate 6 are specifically designed. In terms of quantity, the number of vents at the top is greater than the number of vents at the bottom. This allows the heated air inside the combustion chamber to rise during combustion and be discharged through the top vents. The larger number of vents at the top results in a larger air volume, creating negative pressure and promoting controllable and active air intake through the bottom vents. In terms of arrangement, the bottom vents are not arranged in a complete circle; there are only vents on the back, with no vents on the front. This makes the front of the double-layer conical plate 2, double-layer conical plate 1, and single-layer conical plate 6 the windward side, blocking wind and making the combustion chamber less susceptible to the influence of outdoor wind, thus improving the stability of combustion inside the combustion chamber. The double-layer conical plate 2, double-layer conical plate 1, and single-layer conical plate 6 have good heat collection properties. The double-layer conical plate 2, double-layer conical plate 1, and single-layer conical plate 6 surround the pot in the combustion chamber, making it difficult for the heat to be blown away by the wind. Moreover, the heat is not only applied to the bottom of the pot, but also passes through the pot body along the gaps in the conical plate, further improving the heat utilization rate.

[0032] Working Principle: This portable cone-shaped outdoor cooking device utilizes a multi-fuel combustion chamber composed of a double-layered cone plate (1), a double-layered cone plate (2), and a single-layered cone plate (6). The double-layered cone plates (1), (2), and (6) are available in single-layer and double-layered structures depending on storage requirements. Assembling the double-layered cone plates (1) and (2) provides stable support for the pot body (4). These plates are made of titanium alloy, aluminum alloy, or stainless steel, possessing good toughness and high-temperature resistance. When using the single-layered cone plate (6), it is wound around the plate using clips to form the multi-fuel combustion chamber. The cone shape formed by the single-layered cone plate (6) secures the pot body (8). The multi-fuel combustion mode can be unlocked by using the support rod (7). Removing the support rod (7) allows the use of the alcohol stove (10). After assembly and securing with clips, the resulting cone shape provides significant load-bearing capacity.

[0033] When the heat source is not the matching alcohol stove 10, such as firewood, charcoal, or solid alcohol, two matching support rods 1-3 and 2-7 are used to pass through the holes, reducing the coverage area of ​​the pot and leaving more space for combustion to support the combustion of multiple fuels. The space enclosed by the double-layer conical plate 1-1 and the single-layer conical plate 6 structure can accommodate multiple fuels. The front of the double-layer conical plate 1-1, the double-layer conical plate 2-2, and the single-layer conical plate 6 becomes the windward side, blocking the wind and making the combustion chamber less affected by the outdoor wind, thus improving the stability of combustion inside the combustion chamber. This allows the device to use multiple fuels and meet the cooking needs of different outdoor scenarios.

[0034] When it needs to be folded up, the double-layer foldable structure of the double-layer conical plate 1 and the double-layer conical plate 2 causes it to roll inward from the unfolded state and be stored inside the pot body 4, achieving compact storage of the device. The single-layer conical plate can also be rolled up and stored inside the pot body 8, thereby improving the convenience of carrying outdoor equipment.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
