The furnace is erected inside the stove body and forms a furnace cavity between the stove body. The side wall of the furnace is arranged with a plurality of vents. The furnace cavity is connected to the outside, and the stove cover is arranged on the top of the furnace. The heat generated by the burning of charcoal in the stove furnace is transferred to the top heating body through the furnace cover. During this period, air can enter the furnace cavity from around the top of the furnace, and oxygen is added to the furnace from all directions through the vents, so that the charcoal is fully burned, which improves the safety of the stove. Since only vents for air in and out are retained around the furnace, the heat is locked in the furnace, and part of the overflowed heat is retained in the furnace cavity, so that the heat loss of the stove is slow, which improves the utilization rate of heat. At the same time, through the protection of the furnace, the sparks of charcoal are blocked by the furnace, which improves the user experience.

[0004] However, when the above technical solution is used, the size of the burning flame in the stove cannot be adjusted. Sometimes, users do not need a very strong flame when grilling at close range, and a large flame is unsafe and has certain dangers. In the past, it was necessary to wait until the fuel was almost burned out and the flame was small before grilling at close range.

[0005] In view of this, the utility model provides an adjustable stove bottom structure. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] A preferred embodiment of an adjustable stove bottom structure provided by the utility model is as follows: Figures 1 to 6As shown: an adjustable stove bottom structure, including an outer shell 1, an inner tank 2 is fixedly connected to the inside of the outer shell 1, a fire gathering ring 3 is attached to the top of the inner tank 2, and auxiliary mechanisms 4 are provided at the bottom of the inner tank 2 and the outer shell 1. The auxiliary mechanism 4 includes an overhead component 41 and a rotating component 42. The rotating component 42 includes a chassis 421, rotating blades 422, a screw 423, a nut 424, a limit block 425 and a handle 426. The chassis 421 is fixedly connected to the bottom of the outer shell 1, and the bottom of the chassis 421 is tightly attached to the rotating blade 422. The inside of the rotating blade 422 is rotatably connected to a screw 423 that penetrates through the inside of the chassis 421 and is rotatably connected thereto, and a nut 424 for fixing the rotating blade 422 is threadedly connected to the surface of the screw 423, and the bottom of the rotating blade 422 is fixedly connected to a limit block 425, and one side of the limit block 425 is fixedly connected to a handle 426.

[0027] In this embodiment, the overhead component 41 includes a combustion cup 411, an overhead plate 412 and a collection tray 413. By setting the overhead component 41, the combustion cup 411 can be placed on the top of the middle part of the firewood, which can effectively prevent the firewood from piling up and causing the gap to be too small to burn well. In addition, recessed holes are provided on the combustion cup 411 and the overhead plate 412. The ash generated by the burning of the firewood will fall onto the collection tray 413 along the recessed holes, and the dust generated by the combustion will be collected centrally by the collection tray 413.

[0028] In this embodiment, the collection tray 413 is placed inside the inner container 2 , an overhead plate 412 is attached to the top of the collection tray 413 , and a combustion cup 411 is placed on the top of the overhead plate 412 .

[0029] In this embodiment, a plurality of sets of fan-shaped air inlets are provided at the bottom of the chassis 421 and the bottom of the rotating blades 422, so as to facilitate the adjustment of the combustion flame in the furnace.

[0030] Example 2

[0031] Based on Example 1, a preferred embodiment of an adjustable stove bottom structure provided by the utility model is as follows: Figures 1 to 6 As shown: three groups of connecting plates 5 are fixedly connected to the bottom of the chassis 421, and connecting shafts 6 are fixedly connected inside the three groups of connecting plates 5. The surfaces of the three groups of connecting shafts 6 are rotatably connected to supporting legs 7, and the bottoms of the three groups of supporting legs 7 are fixedly connected to bottom pads 8.

[0032] In this embodiment, the connecting plate 5 is located on the rotation trajectory of the supporting tripod 7, and the supporting tripod 7 forms a fixed structure through the connecting plate 5. Since the supporting tripod 7 is rotationally connected to the connecting shaft 6, when the base pad 8 contacts the ground, the supporting tripod 7 will flip upward under the influence of gravity. Because the connecting plate 5 is located on the rotation trajectory of the supporting tripod 7, the connecting plate 5 will limit the supporting tripod 7 and prevent it from continuing to rotate upward.

[0033] The working principle and use process of the utility model are as follows: first, when the stove is used, firewood is piled inside the inner tank 2, and then the firewood is ignited. By setting the overhead component 41, the combustion cup 411 can be placed on the top of the middle part of the firewood, which can effectively prevent the firewood from piling up together, resulting in a small gap and poor combustion. In addition, the combustion cup 411 and the overhead plate 412 are both provided with concave holes, and the ash generated by the burning of the firewood will fall onto the collection plate 413 along the concave holes. The dust generated by the burning is collected by the collection plate 413. When the dust needs to be cleaned, it is only necessary to clean the collection plate 413.

[0034] By setting the rotating component 42, when it is necessary to adjust the size of the combustion flame, the limit block 425 is pushed by the handle 426, and the rotating blade 422 fixedly connected to the limit block 425 will also rotate around the screw 423. When the fan-shaped air inlet on the chassis 421 and the fan-shaped air inlet on the rotating blade 422 are fully opened and unobstructed, the combustion flame is at its maximum. When the fan-shaped air inlet on the chassis 421 and the fan-shaped air inlet on the rotating blade 422 are completely overlapped and blocked, the combustion flame is at its minimum, thereby achieving the purpose of adjusting the combustion flame. By setting the limit block 425, when the limit block 425 is rotated to the far left or far right, the fan-shaped air inlet will limit it, making it impossible for the handle 426 to continue to rotate.

[0035] By setting up the supporting tripod 7, since the supporting tripod 7 is rotationally connected to the connecting shaft 6, when the base pad 8 contacts the ground, the supporting tripod 7 will flip upward due to the influence of gravity. Since the connecting plate 5 is located on the rotation trajectory of the supporting tripod 7, the connecting plate 5 will limit the supporting tripod 7 and prevent it from continuing to rotate upward, thereby achieving the purpose of fixing the supporting tripod 7 and the base pad 8.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
