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

[0026] Embodiments of this utility model, such as Figures 1 to 7 As shown, an outdoor folding stove is provided, including a stove base 1, a telescopic stove cylinder mechanism, and a pot rack mechanism.

[0027] The furnace base 1 is provided with a base plate 11 at the bottom. The base plate 11 is a circular plate and serves as a foundation for placement, providing stability to the bottom.

[0028] The furnace base 1 also includes the combustion chamber base 12, which is mounted on the base plate 11. The furnace base 1 is annular in shape. The telescopic furnace cylinder mechanism is provided on the outer ring of the furnace base 1. A furnace bridge 2 is installed inside the furnace base 1 and is fixed to the combustion chamber base 12 by snap-fit ​​or welding. An air damper 13 is provided on the side wall of the furnace base 1. The furnace base 1 holds fuels such as firewood and charcoal through the furnace bridge, or connects to a gasification mechanism through the air damper. The specific fuel selection and gasification mechanism configuration are well known to those skilled in the art and will not be described in detail here.

[0029] The telescopic furnace cylinder mechanism includes multiple combustion rings 3, each with a ring-shaped structure. The upper and lower combustion rings 3 are fitted together. Each combustion ring 3 has a sliding support groove 31 on its outer wall, comprising an upper sliding section and a locking section, which are connected. The upper sliding section is longitudinally positioned, and the locking section is horizontally positioned.

[0030] Preferably, the end of the locking segment away from the connection point may also be provided with a limiting recess to prevent the adjacent combustion rings 3 from rotating horizontally due to accidental contact, thereby causing them to detach from the locking segment and enter the upper sliding segment, forming an unstable state.

[0031] Preferably, the upper sliding groove and the snap-fit ​​groove are connected to form an inverted L shape.

[0032] Preferably, each of the combustion rings 3 has four sets of sliding support grooves 31 on its outer wall. The sliding support grooves 31 are recessed into the outer wall of the combustion rings 3 by means of a groove.

[0033] The inner ring of the combustion ring 3 is provided with a support protrusion 32 corresponding to the sliding support groove 31. The support protrusion 32 is slidably connected and limited within the sliding support groove 31.

[0034] When the support protrusion 32 moves in the upper sliding section of the sliding support groove 31, the adjacent inner and outer combustion rings 3 are relatively extended or contracted. When the support protrusion 32 moves in the snap-fit ​​section, it forms upper and lower limits to prevent the adjacent inner and outer combustion rings 3 from moving up and down relative to each other.

[0035] Preferably, each combustion ring 3 has four sets of supporting protrusions 32 on its inner wall. Correspondingly, the outer wall of the combustion chamber base 12 has a sliding support groove 31. The multiple combustion rings 3 are sequentially interlocked and extended to form a combustion chamber inside. Users can adjust the number of layers of the combustion rings 3 according to different needs, thereby adjusting the multi-stage expansion height of the furnace body and the depth of the internal combustion chamber.

[0036] The pot support mechanism includes a pot support ring 4 and supporting legs 41. The pot support ring 4 is movably fitted onto the outermost combustion ring 3. A supporting protrusion 42 is provided on the inner wall of the pot support ring 4, corresponding to the sliding support groove 31 on the outer wall of the outermost combustion ring 3. The supporting protrusion 42 is slidably connected within the sliding support groove 31.

[0037] In addition, the sliding support groove 31 structure provided on the combustion ring 3 and the pot frame ring 4 can also be formed by material enclosure, in which case the edge enclosure of the sliding support groove 31 protrudes from the surface of the combustion ring 3 and the pot frame ring 4.

[0038] A support base is provided at the edge of the pot rack ring 4, and the support base protrudes from the pot rack ring 4. A rotating shaft is provided on the support base. A rotating shaft hole is provided on the support foot 41, and the rotating shaft hole is rotatably sleeved on the rotating shaft, so that the support foot 41 is rotatably mounted on the support base. Preferably, the support foot 41 is concave. In the use state, the edge of the support foot 41 is limited and locked into the support base; in the storage state, the support foot 41 is stored and fastened to the support base.

[0039] Preferably, the base plate 11 and the combustion chamber base 12 are integrally formed.

[0040] like Figure 5-7 The stove is also equipped with a cookware 5, which is designed according to the size of the stove. The inner cavity of the cookware 5 can accommodate the stove when the stove is folded up. When the stove is folded up, the stove can be placed inside the cookware 5. When the stove is unfolded, the stove can support the cookware 5 and heat it.

[0041] Preferably, the burner bridge 2 can be replaced and installed according to the user's needs. When using gas as fuel, the burner bridge 2 needs to be replaced with a gas stove core. When grilling, the cookware can be replaced with a grill rack. When using firewood, a fire-concentrating ring can also be installed on top. The settings for the burner bridge and cookware type on the stove are standard in the stove industry, and those skilled in the art can adjust and select them according to their needs, which will not be elaborated here.

[0042] Usage process: In the unfolded state, the pot rack ring 4 and the combustion ring 3 are unfolded sequentially. Specifically, the support protrusion 42 on the inner wall of the pot rack ring 4 is slid along the upper section of the sliding support groove 31 on the outermost outer wall of the combustion ring 3, and then rotated to the end of the locking section to form a limited unfolding. Next, the support protrusion 32 on the inner wall of the outer combustion ring 3 is slid along the upper section of the sliding support groove 31 on the outer wall of the adjacent inner combustion ring 3, and then rotated to the end of the locking section to form a limited unfolding. The innermost combustion ring 3 extends relative to the combustion chamber base 12. After unfolding, the support foot 41 is rotated and unfolded to form a receiving state for placing the pot 5.

[0043] In the stowed state, the adjacent support protrusions 32 are moved in the opposite direction along the inverted L-shaped sliding support groove 31, so that the pot rack ring 4 and the combustion ring 3 form a nested storage effect relative to the combustion chamber base 12, allowing the support feet 41 to rotate and lower to the outside of the pot rack ring 4. The pot 5 is fastened above the telescopic furnace cylinder mechanism and the pot rack mechanism in the stowed state, as shown. Figure 5 As shown.
