Therefore, they should not be construed as limiting the scope of protection of this application.

[0030] like Figures 1 to 8 As shown, similar to other wood-fired stoves with ovens, the wood-fired stove provided in this application includes a stove 100, a chimney pipe 200 for venting smoke from the stove 100, and an oven 700 installed on the chimney pipe 200. The oven 700 has a flue gas inlet 210 connected to the chimney pipe 200. The chimney pipe 200 is generally vertically installed, connecting to the upper part of the stove 100 to achieve smoke and ventilation, and also to transport the heated smoke from the stove 100 to the oven 700 through the flue gas inlet 210. The oven 700 is a cavity-type box, which can be made of lightweight metal or alloy materials such as stainless steel. Similar to other ovens, the oven 700 of this application should also have a door, which can be a double door, a single door as shown in the attached drawings, or other door structures for taking out and placing food.

[0031] The main improvement of the present application is that a cover 300 is rotatably connected to the flue gas inlet 210, and a switch 400 is provided outside the oven 700 to control the rotation of the cover 300, so that the cover 300 can cover or open the flue gas inlet 210 after rotation. Preferably, the cover 300 has a size larger than that of the flue gas inlet 210, so as to completely cover the flue gas inlet 210. Since the chimney pipe 200 is usually made of a circular pipe, the cover 300 is preferably an arc-shaped plate to fit the chimney pipe 200. The cover 300 can be rotatably connected to the oven 700 by a hinge or a shaft. In particular, the cover 300 can be rotatably connected to the output shaft of a motor, and the switch 400 is an electric switch, so that the rotation of the cover 300 is controlled by electricity.

[0032] Reference Figures 3 to 6 In an alternative embodiment, the cover 300 is rotatably connected to the oven 700 by a mechanical control mode. Specifically, the switch 400 includes a pull rod 410, one end of which is used to pull the cover 300, and the other end of which penetrates to the outside of the side wall of the oven 700. More specifically, the cover 300 is fixedly connected to a pivot 310, and a sleeve 320 is rotatably sleeved on the pivot 310, the sleeve 320 is fixedly installed in the oven 700, and the pull rod 410 is connected to the pivot 310. The switch 400 further includes a connecting plate 420, which is fixedly connected to the pivot 310 and provided with a connecting hole 421, and the end of the pull rod 410 is hooked on the connecting hole 421. In use, by pushing or pulling the pull rod 410, the pivot 310 can be rotated by a certain angle in the axial direction constrained by the sleeve 320, so as to open or close the flue gas inlet 210. The switch 400 and the rotation mode of the cover 300 have a simple structure and are easy to control, and the control process is not prone to errors.

[0033] In this embodiment, the chimney pipe 200 penetrates through the oven 700, and the flue gas inlets 210 are arranged on the pipe wall of the chimney pipe 200 located in the oven 700, and the pivot 310 is arranged beside the chimney pipe 200. The flue gas inlets 210 are provided with two, respectively located at the bottom and top of the oven 700, so as to realize the purpose of simultaneously introducing hot flue gas from top and bottom. At this time, the sleeve 320 should also be provided with two, so as to sufficiently constrain the pivot 310.

[0034] In order to firmly mount the oven 700 on the chimney pipe 200, at least one pipe clamp 500 is provided on the chimney pipe 200, which pipe clamp 500 comprises a sleeve ring 510 sleeved on the chimney pipe 200, the sleeve ring 510 is provided with a broken section, and a bolt 520 is connected between the two ends of the broken section, which is used to tighten the sleeve ring 510 on the chimney pipe 200 after being screwed, and the sleeve ring 510 is fixedly connected to the oven 700. Obviously, the pipe clamp 500 should be provided as two, and fixedly connected to the bottom and top of the oven 700 respectively; at this time, the two sleeves 320 mentioned above can be fixedly connected to the outer sides of the two sleeve rings 510 respectively.

[0035] Reference Figure 4 , 5 and 7, in an alternative embodiment, the oven 700 is also provided with a grill 600. The grill 600 comprises a hanging rod 610, an inner ring 620, an outer ring 630 and a plurality of connecting rods 640; the inner ring 620 is sleeved on the hanging rod 610; the hanging rod 610 is suspended at the top of the oven 700, and the bottom is provided with an anti-falling block 611 to prevent the inner ring 620 from falling off; the outer ring 630 is wrapped outside the inner ring 620; the plurality of connecting rods 640 are fixedly connected between the inner ring 620 and the outer ring 630.

[0036] In this embodiment, the hanging rod 610 is mainly made of a bolt, a through hole is opened at the top of the oven 700, the shank of the bolt passes through the through hole, and the sizes of the head at both ends of the bolt and the nut should be larger than the hole diameter of the through hole; as shown in Figure 7 , at this time, the nut at the lower end is used as the anti-falling block 611. In this way, it can be ensured that the entire grill 600 can be suspended in the oven 700 and can be rotated, and after rotation, food can be conveniently hung or taken out of the oven 700. In order to ensure the strength of the top of the oven 700, so as to be able to suspend heavier food, a reinforcing rib or the like structure can be provided on the top of the oven 700.

[0037] Reference Figure 1 , 2 , 3 and 8, in an alternative embodiment, the stove 100 comprises a base 110, a cylindrical stove wall 120 provided on the top of the base 110, an inner container 130 provided in the stove wall 120 for burning fire, a platform 140 provided on the top of the stove wall 120; the platform 140 is provided with a cooking hole 141 exposing the top opening of the stove wall 120; the front end of the stove wall 120 is provided with a feeding port 121, and the upper part of the rear end is provided with a flue gas outlet 122, which is connected by pipeline between the flue gas outlet 122 and the chimney pipe 200; the base 110 is provided with an ash outlet 111 communicating with the bottom of the stove wall 120.

[0038] In use, the feed inlet 121 is used to put in firewood, the ash outlet 111 is used to discharge ash, the platform 140 can be used to place and process food materials, and the hearth 141 is used to put in a pot for cooking food. The feed inlet 121 and the ash outlet 111 can each be provided with an openable door or cover; the ash outlet 111 can even be provided with a drawer for facilitating ash cleaning.

[0039] In this embodiment, the inner container 130 comprises a barrel 131 and a partition 132 arranged at the lower part of the barrel 131; the partition 132 is provided with ash falling holes 133, which are a plurality of waist-shaped holes; the barrel 131 is provided with a first opening 134 and a second opening 135 on the side wall, and the first opening 134 and the second opening 135 are respectively located above and below the partition 132.

[0040] The first opening 134 and the second opening 135 respectively correspond to the positions of the feed inlet 121 and the ash outlet 111; a plurality of ventilation openings can be further arranged beside the second opening 135 to facilitate ventilation and ensure sufficient combustion of the firewood. In use, the firewood is burned on the partition 132, and the generated ash falls through the ash falling holes 133 to the lower part.
