[0029] Embodiment 1

[0030] Please refer to Figures 1 to 4 , a heating device 100 provided for the first embodiment of the present invention, including a furnace body 10, an adjusting mechanism 20 and a heat extraction mechanism 30.

[0031] Among them, a combustion chamber 11 is provided inside the furnace body 10, and a first heat exhaust port 12 and a second heat exhaust port 13 are provided on the furnace body 10; the adjusting mechanism 20 is movably connected relative to the furnace body 10 so as to be able to synchronously adjust the second heat exhaust port 13 to become smaller or larger when adjusting the first heat exhaust port 12 to become larger or smaller; the heat extraction mechanism 30 is communicated with the second heat exhaust port 13.

[0032] The above heat supply device 100 is provided with an adjusting mechanism 20 to adjust the heat supply amount to the furnace body 10. When adjusting, the first heat discharge port 12 is adjusted to become larger or smaller, and at the same time, the second heat discharge port 13 is synchronously adjusted to become smaller or larger. When the second heat discharge port 13 becomes larger and the first heat discharge port 12 becomes smaller, more heat can be discharged through the second heat discharge port 13; when the second heat discharge port 13 becomes smaller and the first heat discharge port 12 becomes larger, less heat can be discharged through the second heat discharge port 13. In this way, the effect of quickly adjusting the heat discharge amount of the second heat discharge port 13 is achieved, that is, the effect of quickly adjusting the temperature of the heat extraction mechanism 30 can be realized.

[0033] Among them, in this embodiment, both the first heat discharge port 12 and the second heat discharge port 13 can be used for discharging heat. The second heat discharge port 13 is used to discharge heat to the heat extraction mechanism 30, and the first heat discharge port 12 is used to discharge heat into the air, so as to realize the adjustment of the temperature of the heat supplied by the second heat discharge port 13 to the heat extraction mechanism 30.

[0034] Among them, please refer to Figures 2 to 4 , when the adjusting mechanism 20 of this embodiment adjusts the first heat discharge port 12 and the second heat discharge port 13, the adjusting mechanism 20 is slidably arranged relative to the furnace body 10 to adjust the opening sizes of the first heat discharge port 12 and the second heat discharge port 13 in a sliding manner, so as to facilitate the hand operation of the user. In other embodiments, the adjusting mechanism 20 can also adjust the sizes of the second heat discharge port 13 and the first heat discharge port 12 in a rotating manner. For example, when the adjusting mechanism 20 adjusts the sizes of the second heat discharge port 13 and the first heat discharge port 12 in a rotating manner, there is an adjusting plate attached to the wall surface of the furnace body 10. The adjusting plate is rotatably arranged relative to the furnace body 10, and the sizes of the second heat discharge port 13 and the first heat discharge port 12 are gradually adjusted by rotation.

[0035] Among them, in this embodiment, the second heat discharge port 13 and the first heat discharge port 12 are arranged on adjacent sides of the furnace body 10. The second heat discharge port 13 is arranged upward, and the first heat discharge port 12 is arranged on the side surface of the furnace body 10, so that heat can be directly led out upward.

[0036] Specifically, when adjusting the second row of heat outlets 13 and the first row of heat outlets 12 by sliding, the adjusting mechanism 20 has a first opening 21 capable of communicating with the second row of heat outlets 13 and a second opening 22 capable of communicating with the first row of heat outlets 12. The first opening 21 and the second opening 22 are arranged in an intersecting manner. Specifically, the adjusting mechanism 20 includes a first plate body 23 and a second plate body 24 arranged vertically. The first opening 21 is provided on the first plate body 23, and the second opening 22 is provided on the second plate body 24. The first plate body 23 and the second plate body 24 slide relative to the furnace body 10 respectively to increase or decrease the overlapping area between the first opening 21 on the first plate body 23 and the second row of heat outlets 13, and simultaneously increase or decrease the overlapping area between the second opening 22 on the second plate body 24 and the first row of heat outlets 12. According to the size of the smoke exhaust area of the first row of heat outlets 12, the heat discharge amount of the second row of heat outlets 13 is adjusted. When the second row of heat outlets 13 becomes larger, more heat can be transported, that is, the temperature of the heat extraction mechanism 30 can be adjusted higher at this time.

[0037] In other embodiments, when adjusting the sizes of the second row of heat outlets 13 and the first row of heat outlets 12 by sliding, and on the premise that the second row of heat outlets 13 and the first row of heat outlets 12 are arranged on adjacent sides of the furnace body 10, the second row of heat outlets 13 and the first row of heat outlets 12 can be arranged in an intersecting manner. At this time, the center points of the first opening 21 and the second opening 22 are located on the same cross-section of the furnace body 10. When pulling the adjusting mechanism 20 relative to the furnace body 10, the effect of adjusting the first row of heat outlets 12 and the second row of heat outlets 13 can also be achieved.

[0038] Please refer to Figures 2 to 4 , in an embodiment of the present utility model, when adjusting the positions of the second row of heat outlets 13 and the first row of heat outlets 12, in order to avoid excessive movement of the adjusting mechanism 20 sliding relative to the furnace body 10, a first limiting structure is provided on the adjusting mechanism 20 to limit the sliding distance of the adjusting mechanism 20 relative to the furnace body 10 along the first direction a. Thus, when the pulling of the adjusting mechanism 20 is in place, the first limiting structure touches the furnace body 10. At this time, the adjusting mechanism 20 cannot move further to achieve the limiting effect.

[0039] Specifically, a threaded hole 26 is provided on the adjusting mechanism 20 of this embodiment. The first limiting structure is a bolt, and the bolt is installed in the threaded hole 26 for abutting against the furnace body 10. In other embodiments, it can also be that a stop block is formed on the adjusting mechanism 20 itself by bending, or a stop block is welded or adhered to the adjusting mechanism 20 to achieve the limiting function.

[0040] Specifically, the second plate body 24 of this embodiment is provided with a screw hole 26. In other embodiments, the screw hole 26 can also be provided on the first plate body 23, or screw holes 26 can be provided on both the first plate body 23 and the second plate body 24 to achieve this.

[0041] It can be understood that since the adjusting mechanism 20 moves on the furnace body 10 in a sliding manner and reciprocates on the furnace body 10, when the adjusting mechanism 20 moves in the second direction b opposite to the first direction a, the adjusting mechanism 20 is provided with a second limiting structure 27. The second limiting structure 27 is used to limit the sliding distance of the adjusting mechanism 20 relative to the furnace body 10 in the second direction b. In this way, through the cooperation of the first limiting structure and the second limiting structure 27, the movement of the adjusting mechanism 20 in the first direction a and the second direction b is limited to avoid excessive movement.

[0042] Specifically, the second limiting structure 27 of this embodiment is a baffle, and the baffle is used to abut against the furnace body 10. Further, the first plate body 23 is provided with a baffle, and the baffle is perpendicular to the first plate body 23. When the adjusting mechanism 20 moves in the second direction b, when the baffle touches the furnace body 10, the adjusting mechanism 20 stops moving.

[0043] Specifically, please refer to Figures 2 to 4 , to facilitate the adjustment of the first heat discharge port 12 and the second heat discharge port 13, the adjusting mechanism 20 includes an adjusting part 28 and a driving part 29. The driving part 29 is used to drive the adjusting part 28 to move, that is, the first limiting structure and the second limiting structure 27 are provided on the adjusting part 28. The adjusting part 28 is provided with the above-mentioned first opening 21 and second opening 22. The driving part 29 is used to drive the adjusting part 28 to move. Specifically, the adjusting part 28 of this embodiment includes a mounting plate 291 and a handle 292 provided on the mounting plate 291. The mounting plate 291 is connected to the adjusting mechanism 20, that is, the adjustment is carried out in a manually driven manner. In other embodiments, the adjusting part 28 can be set as a driving mode of a motor and a gear, and an electric mode is adopted to have a higher adjustment efficiency.

[0044] Among them, the handle 292 of this embodiment is installed on the second limiting structure 27. When installing the handle 292, the adjusting part 28 includes the above-mentioned first plate body 23 and second plate body 24, and the handle 292 is installed on the second limiting structure 27 through the mounting plate 291.

[0045] Please refer to Figure 1 , in an embodiment of the present utility model, the furnace body 10 includes a primary combustion furnace 14 and a secondary combustion furnace 15. The combustion chamber 11 includes a primary combustion chamber 111 and a secondary combustion chamber 112. The primary combustion furnace 14 is provided with the primary combustion chamber 111, and the secondary combustion furnace 15 is provided with the secondary combustion chamber 112;

[0046] The primary combustion chamber 111 is used for feeding materials for fuel combustion to generate flue gas; the secondary combustion chamber 112 is connected to the primary combustion chamber 111 and is used for burning the flue gas to generate heat and discharging it through the second heat discharge port 13. The adjusting mechanism 20 is installed in the secondary combustion chamber 112. By burning materials in the primary combustion chamber 111 and allowing the flue gas generated by the combustion to enter the secondary combustion chamber 112 and be fully mixed with oxygen for sufficient combustion, the final heat is directed to the heat extraction mechanism 30 and used in devices such as cooking appliances and barbecue appliances.

[0047] Among them, the materials can be biomass materials, such as straw, cattle and sheep manure, rice straw, rice husks, peanut shells, corncobs, cottonseed hulls, etc., and particulate environmental protection new energy materials produced by processing "three leftovers", and can also be charcoal and wood combustion substances.

[0048] Furthermore, when feeding materials into the primary combustion chamber 111, a feeding funnel can be provided in the primary combustion chamber 111 to facilitate the input of materials.

[0049] Furthermore, since the heat extraction mechanism 30 may also generate flue gas, the heating device 100 of this embodiment further includes a smoke guide pipe 40. The smoke guide pipe 40 is respectively connected to the secondary combustion chamber 112 of the furnace body 10 and the heat extraction mechanism 30 to be able to discharge the excess flue gas.

[0050] The above heating device 100, by means of setting the adjusting mechanism 20, can synchronously adjust the sizes of the first heat discharge port 12 and the second heat discharge port 13 by driving the movement of the adjusting mechanism 20, so as to quickly adjust the firepower and realize quickly adjusting the temperature of the heat extraction mechanism 30.

The rotating plate is rotatably arranged relative to the furnace body 10, and the driving member is used to drive the rotating plate to rotate. For example, the driving member can be set as a cylinder, and the telescopic movement of the cylinder drives the rotating plate to rotate. When the rotating plate rotates, the effect that the opening of the first heat discharge port 12 becomes larger and the opening of the second heat discharge port 13 becomes smaller can be achieved, or the effect that the opening of the first heat discharge port 12 becomes smaller and the opening of the second heat discharge port 13 becomes larger can be achieved.
