[0028] Embodiment:

[0029] AsFigures 1 to 5 As shown in the figure, a heating stove of the present invention includes a base 1 and a tabletop. A main combustion chamber 4 and an oven 13 adjacent to the main combustion chamber 4 are arranged between the base 1 and the tabletop; a tear-type grate 3 is arranged at the bottom of the main combustion chamber 4, and a dry distillation type coal storage chamber 6 is arranged at the side of the main combustion chamber 4, and a corresponding sealing cover 7 is provided; a coal outlet is arranged at the lower end of the dry distillation type coal storage chamber 6, and the coal outlet is matched with the tear-type grate 3; a fire concentrating port is arranged at the upper part of the main combustion chamber 4, and a furnace cover 9 corresponding to the position of the fire concentrating port is arranged on the tabletop; a smoke exhaust pipe 10 communicated with the fire concentrating port is arranged outside the oven 13. In the heating stove of the present invention, through the cooperation of the base 1, the tabletop, the main combustion chamber 4, the oven 13, the tear-type grate 3, the dry distillation type coal storage chamber 6, the sealing cover 7, the coal outlet, the fire concentrating port 8, the furnace cover 9 and the smoke exhaust pipe 10, a secondary combustion chamber 5 is formed at the lower part of the dry distillation type coal storage chamber 6. The dry distillation and return combustion gasification is to preheat and dry distill the coal in advance through the secondary combustion chamber 5, and convert the smoke-producing substances in the coal into combustible gas in advance for combustion in the main combustion chamber 4. The front end and the rear end of the main combustion chamber 4 are equipped with secondary air inlets 16, which can supply secondary air to the furnace when the combustion in the furnace is oxygen-deficient, making the flame burn more fully, and solving the problems of smoke generation and unstable combustion caused by directly adding coal. It should be noted that the fire concentrating port is a spiral fin fire concentrating cylinder, which can provide higher firepower for the furnace cover 9, and a frying pan can be placed on the furnace cover 9 for frying and other operations. The smoke outlet is changed to be arranged on the side, and a three-way joint is installed, which is convenient for installing a large-diameter pot on the furnace cover 9 and improving the cooking use range.

[0030] As a preferred embodiment, the tear-type grate 3 includes fixed grate bars 18 and movable grate bars 19 arranged at intervals; a rotating rod 20 is further included and is arranged below the fixed grate bars 18 and the movable grate bars 19 and is connected to the movable grate bars 19. The rotating rod 20 extends out of the main combustion chamber 4 and is matched with a rocker 21. After such a design, during use, by rocking the rocker 21 back and forth, the movable grate bars 19 can be moved back and forth to drive the coal in the secondary combustion chamber 5 to the main combustion chamber 4, and at the same time, the accumulated furnace ash can also fall rapidly.

[0031] As a preferred embodiment, a fixed support rod is arranged on the rotating rod 20, and the fixed support rod is rotatably connected to the side of the movable grate bars 19. After such a design, when rocking the rocker 21, the fixed support rod rotates relative to the movable bars 19, which can be more flexible.

[0032] As a preferred embodiment, serrated structures are arranged on the upper surfaces of the fixed grate bars 18 and the movable grate bars 19. After such a design, when the serrated structure on the movable grate bars 19 moves towards the main combustion chamber 4, the charcoal in the secondary combustion chamber 5 can be conveniently hooked out through the serrated structure, and at the same time, larger charcoal blocks can also be appropriately broken, making the operation more convenient.

[0033] As a preferred embodiment, a drawer - type ash - receiving box 2 is arranged below the tear - type furnace bridge 3 and is provided with an air - adjusting port 22. After such a design, the drawer - type ash - receiving box 2 can be directly pulled out, facilitating the cleaning of carbon ash. The air - adjusting port 22 can adjust the air to ensure sufficient oxygen and complete combustion.

[0034] As a preferred embodiment, secondary air - distributing ports 16 are arranged at both the front end and the rear end of the main combustion chamber 4, making the flame burn more fully and solving the problems of smoke generation and unstable combustion caused by directly adding coal.

[0035] As a preferred embodiment, a penetrating air duct rotating shaft 14 is arranged above the main combustion chamber 4, and a turning plate 15 is arranged on the air duct rotating shaft 14. According to the actual requirements, the air duct rotating shaft 14 can be rotated externally to change the position of the turning plate 15, allowing the flue gas to move along Figure 1 the two directions indicated by the two kinds of arrows for switching. One is to directly enter the exhaust pipe 10, which is the fast - burning path, and the other is to bypass the bottom of the oven 13 and enter the exhaust pipe 10, which is the slow - burning and heat - preservation path. A decompression ventilation port 12 is installed below the slow - burning and heat - preservation path and is provided with an ash - cleaning cover 11. While facilitating ash cleaning, it can also reduce the negative pressure air extraction of the exhaust pipe 10 when sealing the furnace, enabling the coal to burn for a longer time, reducing carbon monoxide generation and preventing harmful gases such as carbon monoxide and sulfur dioxide from remaining in the room and causing danger.

[0036] As a preferred embodiment, the oven 13 and the main combustion chamber 4 are separated by a heat - conducting metal plate, and multiple baking layers are arranged in the oven 13. After such a design, food can be baked on the baking layers, which is safe and convenient.

[0037] As a preferred embodiment, a secondary gasification pipe 8 is arranged at the upper part of the main combustion chamber 4 and is provided with a corresponding regulating valve 17, and multiple secondary gasification holes are arranged on the secondary gasification pipe 8. After such a design, oxygen can be supplied in multiple directions, increasing the combustion oxygen, making the gasification more uniform, increasing the flue gas volume, and reducing carbon monoxide emissions.

[0038] Finally, it should be noted that: the above - mentioned embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
