[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1:

[0027] like Figure 1-Figure 8As shown, a portable miniature stove comprises a first sleeve 1 and a second sleeve 3. The first sleeve 1 and the second sleeve 3 are nested together. A first pot body 8 is welded inside the outer end of the first sleeve 1, and a second pot body 5 is welded inside the outer end of the second sleeve 3. Ventilation holes 2 are formed on the outer walls of the middle parts of the first sleeve 1 and the second sleeve 3 to facilitate ventilation and to facilitate the placement and removal of the fire source. Two handles 4 are symmetrically welded on the outer walls of the first sleeve 1 and the second sleeve 3 near the outer ends. At least one height adjustment device 7 is provided at the fixing position of the first sleeve 1 and the second sleeve 3. The height adjustment device 7 is used to adjust the distance between the first pot body 8 and the second pot body 5, thereby adjusting the distance between the fire source and the pot body. A limiting slide groove 6 is formed on the second sleeve 3 corresponding to the position of the height adjustment device 7. At least one guide groove 9 is formed on the inner wall of the first sleeve 1, and a convex rib 10 is formed on the outer wall of the second sleeve 3 to cooperate with the guide groove 9. The convex rib 10 is formed on the guide groove 9. When the locking cam 75 is in the locked state, the locking cam 73 is in the locked state, and the locking cam 73 is in the locked state, so that the locking cam 73 can be locked to the locking cam 73 by the locking cam 73a.

[0028] In this embodiment, the first sleeve 1 and the second sleeve 3 have the same appearance, and the cross-sections of the first sleeve 1 and the second sleeve 3 are any one of a circle and a regular polygon, so that the first sleeve 1 and the second sleeve 3 can be conveniently nested together.

[0029] In this embodiment, the second pot body 5 and the first pot body 8 are both made of stainless steel. The volume of the first pot body 8 is larger than the volume of the second pot body 5. The uses of the two pot bodies can be the same or different. The two different pot bodies are suitable for use in different occasions.

[0030] In this embodiment, a transmission gear 76 is keyed to the inner end of the rotating shaft 71, and a rack 77 is fixed on the inner wall of the second sleeve 3 near the limiting slide groove 6. The rack 77 is meshed with the transmission gear 76. When the rotating shaft 71 rotates, it drives the transmission gear 76 to rotate, thereby driving the rack 77 to move up and down. When the rack 77 moves up and down, it drives the second sleeve 3 and the first sleeve 1 to move relative to each other.

[0031] Embodiment 2:

[0032] like Fig. 9 As shown, the content of this embodiment is substantially the same as that of the first embodiment, except that:

[0033] In this embodiment, a driving bevel gear 79 is keyed to the inner end of the rotating shaft 71, and the driving bevel gear 79 is rotatably installed in the reversing box 78 through a bearing. A transmission bevel gear 710 meshing with the driving bevel gear 79 is rotatably installed in the reversing box 78, and a threaded hole is formed in the center of the transmission bevel gear 710. A screw rod 711 is fixed at a position close to the limiting slide groove 6 on the inside of the second sleeve 3, and the screw rod 711 is rotatably installed with the transmission bevel gear 710. When the rotating shaft 71 rotates, the driving bevel gear 79 is driven to rotate, and when the driving bevel gear 79 rotates, the transmission bevel gear 710 is driven to rotate. When the transmission bevel gear 710 rotates, the screw rod 711 is driven to rise and fall, and when the screw rod 711 is lifted and lowered, the second sleeve 3 and the first sleeve 1 are driven to move relative to each other.

[0034] The working principle of the present invention is as follows: when in use, the matching position of the first sleeve 1 and the second sleeve 3 is adjusted by twisting the hand wheel 72, and then the first sleeve 1 or the second sleeve 3 is turned upside down on the ground, and the fire source is placed on the pot body below through the ventilation hole 2, and the fire source is ignited (the fire source can be a candle, an alcohol lamp, a burner, etc.). The heat generated by the fire source heats the pot body above, and water and food are put into the pot body for cooking, wherein the first pot body 8 and the second pot body 5 can be the same, or one can be a steaming pot and the other can be a frying pan, and the diameters of the pot bodies can be the same or different. Different pot body diameters can meet the needs of different number of people. When in use, after separating the movable locking piece 73 from the fixed locking piece 75, the hand wheel 72 can be twisted to adjust the distance between the second pot body 5 and the first pot body 8. After the adjustment is completed, the movable locking piece 73 is buckled with the fixed locking piece 75 to prevent the rotating shaft 71 from continuing to rotate, thereby adjusting the distance between the fire source and the pot body, and then adjusting the amount of heat received by the pot body to prevent the pot body temperature from being too low or too high to affect cooking.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
