DETAILED DESCRIPTION

[0022] The following will further describe the specific implementation of the utility model in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0023] Embodiment 1

[0024] This embodiment provides a stove, such as Figure 1-3As shown, it includes a furnace body 100, the furnace body 100 has a combustion chamber 110, a combustion frame 200 is placed in the combustion chamber 110, the combustion chamber 110 has a take-out opening so that the combustion frame 200 can be taken out of the combustion chamber 110, the combustion frame 200 includes a frame body 210 with an opening facing upward, the bottom of the combustion chamber 110 has a first ash drop opening, the combustion frame 200 is placed above the first ash drop opening, and the bottom of the frame body 210 is provided with a second ash drop opening 230. When in use, the combustion frame 200 can be taken out of the combustion chamber 110 first, fuel can be added into the combustion frame 200 from the upper opening of the combustion frame 200, and after the fuel in the combustion frame 200 is ignited, the combustion frame 200 can be put into the combustion chamber 110 from the take-out opening, which is convenient for fueling operations and ignition operations. An ash box 300 is provided below the first ash outlet. Ashes after fuel combustion can pass through the second ash outlet 230 and the first ash outlet and fall into the ash box 300. The ash box 300 can be removed from the furnace body 100 for cleaning.

[0025] like Figure 2 , 3 As shown, the bottom of the frame 210 includes an upper bottom 250 and a lower bottom 260, and a receiving cavity 240 is provided between the upper bottom 250 and the lower bottom 260, and a second ash outlet 230 is provided on the upper bottom 250 and the lower bottom 260. In the process of igniting the fuel, an ignition item can be placed in the receiving cavity 240 first, and the ignition item can be an alcohol cotton. After the ignition item burns, the fuel is heated and ignited from the bottom of the fuel, and the user does not need to hold the igniter for a long time, thereby improving the convenience of the ignition operation. In addition, the receiving cavity 240 is connected from front to back, and air can also enter the cavity where the fuel is located from the receiving cavity 240 to provide oxygen for combustion, which is conducive to the continuous combustion of the fuel.

[0026] like Figure 2 , 3 As shown, the upper bottom 250 is inclined downward from the middle to both sides, thus forming a triangular accommodating cavity 240. In other optional embodiments, the upper bottom 250 and the lower bottom 260 can also be arranged in parallel.

[0027] like Figure 2 , 3 As shown, the side wall of the frame 210 is hollowed out. The bottom and surrounding walls of the frame 210 are all hollowed out. Specifically, the frame 210 is formed by crisscrossing metal strips, and there is a gap between adjacent horizontal metal strips or adjacent vertical metal strips to form a hollow structure. In other optional embodiments, the frame 210 can also be formed by connecting a plate-like structure, and holes are opened on the plate-like structure to form a hollow structure.

[0028] like Figure 1 , 2As shown, the frame 210 is provided with a barrel 220, and the stove includes an operating workpiece 400, and the operating workpiece 400 is inserted into the barrel 220 to take and place the combustion frame 200. The operating workpiece 400 includes a rod 410, one end of the rod 410 is provided with a handle 420, and the other end is provided with a hook 430, and the hook 430 passes through the barrel 220. The combustion frame 200 can be easily taken and placed by the operating workpiece 400.

[0029] like Figure 1 As shown, the furnace body 100 is provided with a detachable chimney 510 or a stove rack above the combustion frame 200, that is, the chimney 510 and the stove rack are interchangeable, and pots can be placed on the stove rack for cooking food. The frame 210 of this embodiment is a rectangular parallelepiped.

[0030] Embodiment 2

[0031] The difference between this embodiment and the first embodiment mainly lies in the structure of the frame 210 and the furnace body 100. The combustion chamber 110 in the furnace body 100 of the first embodiment extends vertically upward, while the combustion chamber 110 of this embodiment extends in a U-shape, the combustion frame 200 is located at one side of the furnace body 100, and the chimney 510 is located at the other side of the furnace body 100.

[0032] Further, if Figure 4-5 As shown, the side wall of the frame 210 has a limiting protrusion 211, so that there is a gap between the side wall of the frame 210 and the side wall of the combustion chamber 110. Since the side wall of the frame 210 has a hollow structure, air can pass through the gap between the side wall of the frame 210 and the side wall of the combustion chamber 110 and then further enter the frame 210 through the hollowing, which is convenient for providing sufficient oxygen for fuel combustion.

[0033] like Figure 5 As shown, the width of the upper end of the frame 210 is greater than the width of the lower end, and the limiting protrusion 211 is located at the upper end of the frame 210. In other optional embodiments, the width of the lower end of the frame 210 may also be greater than the width of the upper end.

[0034] like Figure 4 As shown, a feeding tube 120 is provided on the table top of the furnace body 100, and the feeding tube 120 is located above the combustion frame 200. The upper end of the feeding tube 120 is covered with a cover plate 520, and the cover plate 520 can be replaced by a funnel 530 to facilitate adding fuel to the combustion frame 200. The cover plate 520 can also be replaced by a stove rack, on which pots are placed for cooking.
