DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] The embodiment of the present application discloses a gas volume regulating structure of a wood-burning stove.

[0025] Reference Figure 1 and Figure 2 , including a furnace body 1 and a smoke exhaust pipe 3, the smoke exhaust pipe 3 is vertically plugged and fixed to the upper end of the furnace body 1, and an adjustment component 16 is horizontally placed in the furnace body 1, and the adjustment component 16 includes a fixing plate 4 and a slide plate 9.

[0026] Reference Figure 3 and Figure 4 The fixed plate 4 consists of a bottom plate 5, two inclined plates 6 and two mounting plates 7. The bottom plate 5 is placed horizontally. The two inclined plates 6 are respectively located on both sides of the bottom plate 5. One side of the inclined plate 6 is integrally arranged on one side of the bottom plate 5 and is inclined upward. The two mounting plates 7 are respectively located on both outer sides of the two inclined plates 6. One side of the mounting plate 7 is integrally arranged on the outer side wall of the inclined plate 6 and is placed horizontally. The upper end surface of the fixed plate 4 has a groove. The upper side wall at one end of the bottom plate 5 is provided with a notch 8, and the notch 8 is vertically corresponding to the smoke exhaust pipe 3.

[0027] The slide plate 9 moves along the length direction of the fixed plate 4. The slide plate 9 consists of a pressing plate 10 and two contact plates 11. The two contact plates 11 are respectively located on both sides of the pressing plate 10. One side of the contact plate 11 is integrally arranged on one side of the pressing plate 10 and is arranged to be inclined upward. The pressing plate 10 abuts against the bottom plate 5, and the contact plate 11 abuts against the inclined plate 6. The slide plate 9 moves back and forth to control the size of the gap 8. When the slide plate 9 is moved to one side of the fixed plate 4, the vent hole is in the maximum state, so that the air in the furnace body 1 circulates, and the combustion power of the firewood in the furnace body 1 is increased. When the slide plate 9 is moved to the other side of the fixed plate 4, the vent hole is in the minimum state, so that the air circulation at the upper end of the furnace body 1 is reduced.

[0028] The side wall of the contact plate 11 is evenly provided with a plurality of first air holes 12 along the length direction, and the side wall of the inclined plate 6 is evenly provided with a plurality of second air holes 13 along the length direction. When the air hole is in the maximum state, the first air hole 12 is located between two adjacent second air holes 13. When the air hole is in the minimum state, the plurality of first air holes 12 and part of the plurality of second air holes 13 correspond to each other.

[0029] Reference Figure 5 Two adjusting bolts 14 are fixed to the bottom thread of the pressing plate 10. The two adjusting bolts 14 are arranged along the length direction of the slide plate 9. Two sliding grooves 15 are opened on the upper side wall of the bottom plate 5, which are connected to each other from top to bottom. The two sliding grooves 15 are for the ends of the adjusting bolts 14 to slide. When the slide plate 9 slides on the fixed plate 4, the ends of the adjusting bolts 14 move in the sliding grooves 15. At the same time, the adjusting bolts 14 prevent the slide plate 9 from moving axially. When the slide plate 9 needs to be moved, the door of the furnace body 1 is opened, and then a tool is inserted into the furnace body 1 to stir the ends of the adjusting bolts 14, so that the adjusting bolts 14 move in the sliding grooves 15, thereby driving the slide plate 9 to move in the groove of the fixed plate 4.

[0030] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
