Description

Technical Field

[0001] This utility model relates to the field of outdoor cooking equipment technology, specifically to a portable and efficient outdoor stove. Background Technology

[0002] Outdoor stoves are primarily used for heating needs in outdoor settings. Most existing modular stoves connect the inner and outer furnace bodies using simple slots, lacking a dedicated two-way positioning structure. This can easily lead to coaxiality deviations after assembly. This not only causes the furnace body to shake during combustion due to vibration or external forces, resulting in safety hazards such as flame deviation and fuel spillage, but also causes uneven width of the air passage between the inner and outer furnace bodies, disrupting oxygen flow stability and indirectly affecting combustion efficiency. Traditional stoves often use a single fixed air inlet design, making it impossible to adjust the oxygen supply according to fuel type or combustion requirements. Although some products have oxygen control structures, they lack an air compression chamber. As a result, the oxygen does not mix sufficiently with the fuel after entering the furnace, leading to incomplete combustion, low heat release efficiency, and the generation of a large amount of black smoke and unburned residue, which wastes energy and increases cleaning costs. Utility Model Content

[0003] This invention provides a portable and efficient outdoor stove to solve the problems mentioned in the background art.

[0004] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0005] An outdoor portable high-efficiency stove includes: a lower furnace plate; and a modular external insulation assembly.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. The following description of at least one exemplary embodiment is illustrative in nature and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figure 1-5 One embodiment of this utility model is a portable and efficient outdoor stove.

[0029] Lower furnace tray 1;

[0030] The spliced ​​external heat insulation assembly 2 includes a first slot 21 and an upper furnace cover plate 23. The first slot 21 is fixedly installed on the top of the lower furnace plate 1, and a second slot 24 is fixedly installed on the bottom of the upper furnace cover plate 23. Multiple external heat insulation and windproof plates 22 are sequentially connected between the bottom of the upper furnace cover plate 23 and the top of the lower furnace plate 1 through the second slot 24 and the first slot 21. The plates are made of double-layer heat insulation metal plates and filled with high-temperature heat insulation cotton in the middle, which can effectively reduce the surface temperature of the furnace body. Each external heat insulation and windproof plate 22 has bent ends, and the bent parts of two adjacent plates are interlocked to form a closed octagonal outer furnace cylinder, which has both windproof and heat insulation functions. The bent parts of every two adjacent external heat insulation and windproof plates 22 are spliced ​​together, and a third slot 26 is installed on the opposite side of each external heat insulation and windproof plate 22.

[0031] The spliced ​​inner furnace assembly 3 includes a fourth slot 31 and an inner furnace plate cover 33. The fourth slot 31 is fixedly installed on the top of the lower furnace plate 1 and located in the inner circle of the first slot 21. The edge of the inner furnace plate cover 33 is bent downward at a right angle and is embedded in the groove of the third slot 26 to achieve precise positioning of the inner furnace and the outer furnace cylinder. The bottom of the inner furnace plate cover 33 is fixedly installed with a fifth slot 34. The bottom of the inner furnace plate cover 33 and the top of the lower furnace plate 1 are connected by the fourth slot 31 and the fifth slot 34 to multiple inner fire chamber plates 32.

[0032] The fuel inlet 5 runs through the space between the outer heat insulation and windproof plate 22 and the inner firebox plate 32.

[0033] Please see Figure 1-3 The outer heat insulation and windproof plate 22 has a smoke exhaust hole 25 on one side. The smoke exhaust hole 25 is located above the inner furnace cover 33 to prevent smoke accumulation. The upper furnace cover 23 has a round hole in the center. The round hole is equipped with a removable hole cover. When closed, it can keep the heat in place. When opened, it can hold pots, kettles and other cooking utensils. The groove paths of the first slot 21 and the second slot 24 are both octagonal.

[0034] Please see Figure 2 and Figure 6 The inner firebox plate 32 has multiple combustion air inlet holes 35, which can make oxygen enter the furnace evenly. The inner furnace plate cover 33 has a round hole in the center, which is equipped with a removable hole cover. When opened, fuel can be added or the combustion status can be observed. When closed, heat loss can be reduced. The groove paths of the fourth slot 31 and the fifth slot 34 are both octagonal.

[0035] Please see Figure 1-7 An annular hollow outer furnace oxygen compression chamber 4 is formed between the outer heat insulation and windproof plate 22 and the inner firebox plate 32. Multiple first controllable air inlets 6 are provided between the top and bottom of the lower furnace plate 1 and below the annular hollow outer furnace oxygen compression chamber 4. A second controllable air inlet 7 is provided between the top and bottom of the lower furnace plate 1 and inside the spliced ​​inner furnace assembly 3, so as to realize the graded control of oxygen supply. The annular hollow outer furnace oxygen compression chamber 4 is formed by the outer heat insulation and windproof plate 22 and the inner firebox plate 32. After the outside air enters through the first controllable air inlet 6, it forms a compressed airflow in the cavity and then enters the inner furnace evenly through the combustion air inlet 35, thereby improving the mixing efficiency of oxygen and fuel.

[0036] Please see Figure 9-10 The first controllable air inlet 6 is slidably fitted with a first controllable air inlet plate 8, and the second controllable air inlet 7 is slidably fitted with a second controllable air inlet plate 9. A first pull plate buckle 10 is installed at the bottom of the first controllable air inlet plate 8, and a second pull plate buckle 11 is installed at the bottom of the second controllable air inlet plate 9. By pushing the pull plate buckle, the opening and closing degree of the air inlet can be adjusted, thereby controlling the amount of oxygen entering the furnace and adapting to the combustion requirements of different fuels.

[0037] Please see Figure 1 , Figure 3 and Figure 9 The fuel inlet 5 includes two opposing horizontal plates 51, which are U-shaped. The inner side of the horizontal plate 51 is provided with a sixth slot 52, and there are two sixth slots 52 near the end of the horizontal plate 51. A vertical plate 53 is provided between the two horizontal plates 51. The vertical plate 53 is engaged with the inner side of the horizontal plate 51 through the sixth slot 52 to form a rectangular fuel inlet channel. When in use, fuel can be added directly through the fuel inlet 5 without disassembling the stove body, which is convenient to operate. When not in use, it can be disassembled and stored in the lower stove plate 1 to reduce the storage volume.

[0038] Working principle: When the stove is needed, place the lower furnace plate 1 on a flat ground, insert the bottom of the eight external heat insulation and windproof plates 22 into the first slot 21 respectively, and align the top of the external heat insulation and windproof plates 22 with the second slot 24 of the upper furnace cover plate 23, so that the bends of the adjacent external heat insulation and windproof plates 22 interlock with each other, completing the assembly of the spliced ​​external heat insulation group 2; insert the bottom of the eight inner fire chamber plates 32 into the fourth slot 31, and align the top with the fifth slot 34 of the inner furnace cover plate 33, completing the assembly of the spliced ​​inner furnace chamber group 3; at the same time, embed the bend edge of the inner furnace cover plate 33 into the third slot 26 to achieve the positioning of the inner furnace chamber and the outer furnace cylinder, and splice the horizontal plate 51 and the vertical plate 53 through the sixth slot 52 to form the fuel inlet 5, and install it at the reserved notch between the external heat insulation and windproof plates 22 and the inner fire chamber plates 32.

[0039] When used outdoors, open the holes of the upper furnace cover 23 and the inner furnace cover 33 in sequence to prepare for subsequent fuel addition. When the hole of the inner furnace cover 33 is opened, fuel can be added to the inner furnace; when the hole of the inner furnace cover 33 is closed, only the fuel inlet 5 is left open for subsequent fuel addition. During use, the opening of the first controllable air inlet 6 can be adjusted by the first pull plate buckle 10, and the opening of the second controllable air inlet 7 can be adjusted by the second pull plate buckle 11; after igniting the fuel, adjust the air intake according to the combustion state: if the flame is weak and there is black smoke, the air intake opening can be increased; if the flame is too strong and the fuel is consumed too quickly, the air intake opening can be decreased.

[0040] If you need to cook, open the hole cover of the upper stove cover plate 23, place the pot in the round hole, and use the heat of the furnace to cook; if you need to heat, keep the hole cover of the upper stove cover plate 23 closed, and heat up through the heat radiation of the outer furnace cylinder. During the process, you can add fuel through the firewood inlet 5.

[0041] After use, once the furnace body has cooled down, disassemble the furnace by removing the horizontal plate 51 and vertical plate 53 of the fuel inlet 5, taking off the upper furnace cover 23, and then taking out the eight outer heat insulation and windproof plates 22 from the first slot 21 and the second slot 24 in sequence. Take off the inner furnace cover 33, and then take out the eight inner firebox plates 32 from the fourth slot 31 and the fifth slot 34 in sequence. Place the outer heat insulation and windproof plates 22, the inner firebox plates 32, the fuel inlet 5, the upper furnace cover 23, and the inner furnace cover 33 into the lower furnace plate 1 to complete the storage. The overall storage volume is reduced, making it easy to carry.
