Embodiment 1

As shown in FIG. 1 to FIG. 7, this embodiment provides a combustion furnace with adjustable firepower. The combustion furnace includes a cylindrical furnace body 1. The furnace body 1 is provided with a combustion chamber 11 in which other combustible materials such as wood are placed. The combustion chamber 11 forms a port above the furnace body 1, into which wood is put. Further, a plurality of air inlets 3 are provided below the side wall of the furnace body 1. The air inlets 3 are provided around the furnace body 1 and are configured to be communicated with the combustion chamber 11. When wood burns in the combustion chamber 11, air can enter the combustion chamber 11 through the air inlets 3, so that the wood can be fully burned. Further, the combustion furnace of this embodiment is further provided with an adjusting mechanism 2. The adjusting mechanism 2 is configured to control the air inlets 3 to be turned on or off.

When in use, users can put the wood into the combustion chamber 11 through the opening 1021 to ignite the wood. When the firepower needs to be increased, the adjusting mechanism 2 can be controlled to turn on the air inlet 3. As shown in FIG. 5, after the air inlet 3 is turned on, oxygen in the combustion chamber 11 is continuously consumed along with the combustion of the wood, so that the external air enters the combustion chamber 11 through the air inlet 3, and the combustion of the wood is stronger. When the firepower needs to be decreased, the adjusting mechanism 2 can be controlled to turn off the air inlet 3. After the air inlet 3 is turned off, the combustion intensity of wood will be gradually weakened along with the continuous consumption of oxygen in the combustion chamber 11, so as to prolong the combustion time of wood. Through the above structural arrangement, users can adjust the firepower of the combustion furnace by controlling the adjusting mechanism 2, so as to meet different requirements. The combustion furnace with adjustable firepower is simple in operation and strong in practicality.

Specifically, the adjusting mechanism 2 of this embodiment includes a baffle 21. The shape of the baffle 21 matches the shape of the furnace body 1. The baffle 21 is provided at the bottom of the furnace body 1 and closely clings to the side wall of the furnace body 1, and is configured to rotate coaxially with respect to the furnace body 1. Further, the baffle 21 is further provided with a plurality of open-holes 211.

Through the above structural arrangement, when the firepower needs to be adjusted to the maximum, the baffle 21 can be rotated so that the air inlet 3 of the baffle 21 overlaps with the air inlet 3 of the furnace body 1, so as to turn on the air inlet 3 of the furnace body 1. When the firepower needs to be decreased, the baffle 21 can also be rotated. When the baffle 21 is rotated, the air inlet 3 of the furnace body 1 will be gradually blocked by the rotating baffle 21, so as to turn off the air inlet 3 of the furnace body 1. The combustion furnace with adjustable firepower is simple in structure and ingenious in design.

Further, the adjusting mechanism 2 of this embodiment further includes a hand-held part 22. One side of the hand-held part 22 extends outward to form a cylindrical projection, so as to form a connecting part 23. The bottom of the side wall of the furnace body 1 is transversely provided with a sliding groove 12 matched with the connecting part 23, and the connecting part 23 is connected with the baffle 21 through the sliding groove 12.

With the above structural arrangement, when the baffle 21 needs to be rotated, the hand-held part 22 can be pushed clockwise or counterclockwise around the furnace body 1 so that the connecting part 23 translates in the sliding groove 12. The translated connecting part 23 will drive the baffle 21 to rotate in the furnace body 1, so as to realize the stepless adjustment of the baffle 21.

Further, a combustion rack 13 in which wood is placed is provided in the combustion chamber 11 of this embodiment. The combustion chamber 11 forms a lower chamber 111 below the combustion rack 13. A plurality of wind shields 4 are provided in the lower chamber 111 to divide the lower chamber 111 into a plurality of chamber units 1111. The combustion rack 13 can be erected on the top of the wind shields 4.

Through the above structural arrangement, when air enters the lower chamber 111 from the air inlet 3 at the bottom of the furnace body 1, air will enter different chamber units 1111, so as to prevent air from forming cyclone turbulence in the lower chamber 111 and improve the combustion efficiency of wood.

Further, a storage rack 14 is further provided in the furnace body 1 of this embodiment. The storage rack 14 is provided below the combustion rack 13, and the combustion rack 13 is provided with a plurality of through-holes 131. As an embodiment, the bottom of the wind shield 4 is provided with a protrusion 41. The storage rack 14 can be erected on the protrusion 41. Through the above structural arrangement, when the wood burns to form ashes, the ashes will fall into the storage rack 14 through the through-holes 131, which is convenient for storage and cleaning.

Further, the furnace body 1 of this embodiment includes a first furnace body unit 101 and a second furnace body unit 102. The second furnace body unit is provided in the first furnace body unit 101. Specifically, in this embodiment, the air inlet 3 is provided at the bottom of the side wall of the first furnace body unit 101. The combustion chamber 11 is provided in the second furnace body unit 102. The diameter of the first furnace body unit 101 is longer than that of the second furnace body unit 102. The bottom wall of the second furnace body unit 102 is higher than the bottom wall of the first furnace body unit 101 to form a first air passage 51 between the side wall of the second furnace body unit 102 and the side wall of the first furnace body unit 101, and form a second air passage 52 between the bottom wall of the first furnace body unit 101 and the bottom wall of the second furnace body unit 102. Further, the bottom wall of the second furnace body unit 102 is provided with an opening 1021 to realize the communication between the combustion chamber 11 and the second air passage 52.

With the above structural arrangement, when wood burns in the combustion chamber 11, air will enter the second air passage 52 between the bottom wall of the first furnace body unit 101 and the bottom wall of the second furnace body unit 102 through the air inlet 3, and then enter the combustion chamber 11 through the opening 1021 in the bottom wall of the second furnace body unit 102.

Further, as shown in FIGS. 5 and 6, in this embodiment, the baffle 21 is provided at the bottom of the first furnace body unit 101 and closely clings to the first furnace body unit 101, and the sliding groove 12 is correspondingly provided on the side wall of the first furnace body unit 101. When the hand-held part 22 is pushed, the baffle 21 will rotate with respect to the first furnace body unit 101.

Further, in this embodiment, the combustion chamber 11 forms an upper chamber 112 above the combustion rack 13. The side wall of the upper chamber 112 is surrounded by an air outlet 6. Air can enter the first air passage 51 through the air inlet 3 and then enter the upper chamber 112 through the air outlet 6. The air entering the upper chamber 112 can further burn the smoke in the upper chamber 112.

Further, the combustion furnace of this embodiment further includes a base 7. The base 7 is provided below the furnace body 1 for supporting the furnace body 1.

Embodiment 2

As shown in FIG. 8 to FIG. 17, this embodiment provides a combustion furnace with adjustable firepower. The combustion furnace includes a square furnace body 1. The furnace body 1 is provided with a combustion chamber 11 in which other combustible materials such as wood are placed. The combustion chamber 11 forms a port above the furnace body 1, into which wood is put. Further, a plurality of air inlets 3 are provided below the side wall of the furnace body 1. The air inlets 3 are provided around the furnace body 1 and are configured to be communicated with the combustion chamber 11. When wood burns in the combustion chamber 11, air can enter the combustion chamber 11 through the air inlets 3, so that the wood can be fully burned. Further, the combustion furnace of this embodiment is further provided with an adjusting mechanism 2. The adjusting mechanism 2 is configured to control the air inlets 3 to be turned on or off.

When in use, users can put the wood into the combustion chamber 11 through the opening 1021 to ignite the wood. When the firepower needs to be increased, the adjusting mechanism 2 can be controlled to turn on the air inlet 3. As shown in FIG. 16, after the air inlet 3 is turned on, oxygen in the combustion chamber 11 is continuously consumed along with the combustion of the wood, so that the external air enters the combustion chamber 11 through the air inlet 3, and the combustion of the wood is stronger. When the firepower needs to be decreased, the adjusting mechanism 2 can be controlled to turn off the air inlet 3. After the air inlet 3 is turned off, the combustion intensity of wood will be gradually weakened along with the continuous consumption of oxygen in the combustion chamber 11, so as to prolong the combustion time of wood. Through the above structural arrangement, users can adjust the firepower of the combustion furnace by controlling the adjusting mechanism 2, so as to meet different requirements. The combustion furnace with adjustable firepower is simple in operation and strong in practicality.

Specifically, the adjusting mechanism 2 of this embodiment includes a baffle 21. The shape of the baffle 21 matches the shape of the furnace body 1. The baffle 21 is provided at the bottom of the side wall of the furnace body and closely clings to the side wall of the furnace body 1 to block the air inlet 3. Further, the baffle 21 can move up and down with respect to the side wall of the furnace body 1 to control the air inlet 3 to be turned on and off.

Through the above structural arrangement, when the firepower needs to be adjusted to the maximum, the baffle 21 can be moved upward to keep the baffle 21 away from the air inlet 3, so as to turn on the air inlet 3 of the furnace body 1. When the firepower needs to be decreased, the baffle 21 can be moved downward to block the air inlet 3, so as to turn off the air inlet 3 of the furnace body 1. The combustion furnace with adjustable firepower is simple in structure and ingenious in design.

Further, the adjusting mechanism 2 of this embodiment further includes a hand-held part 22, a connecting part 23 and a connecting rod 24. The top of the side wall of the furnace body 1 is longitudinally provided with a sliding groove 12. One end of the connecting part 23 is connected with the hand-held part 22, and the other end thereof is connected with one end of the connecting rod 24 through the sliding groove 12. The other end of the connecting rod 24 is connected with the baffle 21.

Through the above structural arrangement, when the baffle 21 needs to be moved upward, the hand-held part 22 can be pushed upward, so that the connecting part 23 translates upward in the sliding groove 12, so as to drive the connecting rod 24 to move upward. The connecting rod 24 moving upward will drive the baffle 21 to move upward in the furnace body 1, so as to turn on the air inlet 3. Similarly, when the baffle 21 needs to be moved downward, the hand-held part 22 can be pushed downward, so that the connecting part 23 translate downward in the sliding groove 12, so as to drive the connecting rod 24 to move downward. The connecting rod 24 moving downward will drive the baffle 21 to move downward in the furnace body 1, so as to turn off the air inlet 3.

Further, in this embodiment, as shown in FIGS. 11 and 12, the furnace body is further provided with a stopper 121 at the sliding groove 12. The stopper 121 is used to fix the connecting part 23 in the sliding part when the connecting part 23 moves in the sliding groove 12.
