Three equally spaced plug-in blocks 11 are provided on the lower outer side of the upper annular furnace body 2. A corresponding plug-in groove 25 is provided on the upper outer side of the lower annular furnace body 2. The plug-in blocks 11 can be inserted into the corresponding plug-in groove 25. The three plug-in grooves 25 provide limiting support for the three plug-in blocks 11, enabling the installation of the upper annular furnace body 1 on the lower annular furnace body 2. This further improves the installation stability of the upper annular furnace body 1 on the lower annular furnace body 2, thereby enhancing the safety of the wood-burning stove structure. For safety, a first annular groove 12 is provided at the lower edge of the inner side of the upper annular furnace body 1, and the first annular groove 12 is snapped onto the upper circumference of the lower annular furnace body 2; the interiors of the upper annular furnace body 1 and the lower annular furnace body 2 are vertically connected, and a furnace opening 21 is provided at the front of the lower annular furnace body 2. In actual application, fuel is put into the interior of the lower annular furnace body 2 through the furnace opening 21, and the pot for cooking is placed on the upper opening of the upper annular furnace body 1. A [unclear text - possibly a typo, should be "on the lower outer side"] is provided. In actual processing, to facilitate the storage and disassembly of the support legs 23, the support legs 23 are configured to include a fixing tube 231 and a support tube 232. The fixing tube 231 is fixedly installed on the lower outer wall of the lower annular furnace body 2. The upper part of the support tube 232 is connected to the fixing tube 231 by a plug-in or threaded connection. In this specific embodiment, the number of support legs 23 is set to 3, and the three support legs 23 are evenly distributed along the circumference of the lower annular furnace body 2.

[0026] Based on the above embodiments, in order to improve the safety of the firewood stove structure, a stove door 22 is hinged to the front side of the stove opening 21. Specifically, the bottom left and right sides of the stove door 22 are hinged to the bottom of the stove opening 21. At the same time, in order to make the stove door 22 automatically fit onto the stove opening 21 when closed by using gravity, the front of the stove opening 21 is tilted in a state where the front is lower and the back is higher.

[0027] This utility model also provides a multifunctional wood-burning stove, including the wood-burning stove structure according to the above embodiment.

Specifically, an annular overlapping plate is provided on the upper outer edge of the main ash collection box 41, and an annular plate 241 is provided on the inner edge of the ash outlet 24. The annular overlapping plates overlap... The main ash collection box 41 is installed on the ash discharge port 24 on the annular plate 241. An opening 411 is provided in the middle of the front side of the main ash collection box 41. The secondary ash collection box 42 is drawer-shaped. The rear part of the secondary ash collection box 42 passes through the opening 411 and is fitted inside the main ash collection box 41. The main ash collection box 41 can be used to collect all the ash, and the secondary ash collection box 42 can be used to collect part of the ash. At the same time, the secondary ash collection box 42 can be pulled out to clean the ash inside, so as to facilitate repeated ash cleaning operations using the secondary ash collection box 42.

[0029] In practical applications, if it is necessary to use this wood-burning stove for grilling, first remove the secondary ash collection box 42 from the main ash collection box 41, then remove the upper annular furnace body 1 from the upper part of the lower annular furnace body 2. Then, the combined structure of the main ash collection box 41, the lower annular furnace body 2 and the grate 3 can be used for grilling. When grilling, charcoal is placed in the secondary ash collection box 41 and the skewers are placed on the upper part of the grate 3.

[0030] In practical applications, both the upper annular furnace body 1 and the lower annular furnace body 2 can support a corresponding type of pot. To enable the upper annular furnace body 1 to support more different types of pots, an adjustable furnace ring assembly 5 is provided on the upper part of the upper annular furnace body 1. Specifically, the adjustable furnace ring assembly 5 includes several adjustable furnace rings, which are connected and overlapped sequentially from the outside to the inside. The outermost adjustable furnace ring can overlap the upper part of the inner wall of the upper annular furnace body 1. Each adjustable furnace ring is ring-shaped. Specifically, the adjustable furnace ring assembly includes three adjustable furnace rings, namely the first adjustable furnace ring 51, the second adjustable furnace ring 52, and the third adjustable furnace ring 53. A second annular plate 54 is provided on the inner ring of ring 53. The outer side of the third adjusting ring 53 overlaps the upper inner side of the upper annular furnace body 1. The outer side of the second adjusting ring 52 overlaps on the second annular plate 54 of the third adjusting ring 53. The outer side of the first adjusting ring 51 overlaps on the second annular plate 54 of the second adjusting ring 52. The inner diameters of the first adjusting ring 51, the second adjusting ring 52 and the third adjusting ring 53 are different, so that different types of pots can be supported. When this multi-functional wood stove is used as a heating stove, in order to improve heating safety, a cover plate 6 is attached to the innermost adjusting ring of the adjusting ring assembly 5. Specifically, the cover plate 6 closes the third adjusting ring 53, and the outer side of the cover plate 6 overlaps on the second annular plate 54 of the third adjusting ring 53.

[0031] Based on the above embodiments, in order to facilitate smoke exhaust, a smoke exhaust port 13 communicating with the interior is provided in the middle of the rear side of the upper annular furnace body 1, and a chimney pipe 14 is fixedly installed on the smoke exhaust port 13. In actual application, the chimney can be installed using the chimney pipe 14.
