[0002] A wood-fired stove is a type of stove that uses firewood as fuel. A stainless steel wood-fired stove is a very practical outdoor living tool. It is very easy to use; simply put firewood into the stove to light it, thereby generating heat to provide you with warmth or for cooking food.

[0003] The existing stainless steel wood-burning stoves with cement furnaces cannot accurately adjust the air intake, thus making it impossible to regulate the combustion efficiency and temperature of the wood through the heat and ash generated by the burning of firewood. Therefore, there is a need to provide a cement furnace for stainless steel wood-burning stoves. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that the air intake cannot be accurately adjusted, thus making it impossible to adjust the combustion efficiency of firewood and the temperature of firewood combustion. Therefore, this invention proposes a cement furnace for a stainless steel wood-burning stove.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cement furnace chamber for a stainless steel wood-fired stove, comprising a main frame and a top plate fixedly installed on its top, the inner wall of the main frame being fitted with heat insulation filling, a bottom plate fixedly installed at the bottom of the main frame, multiple casters fixedly installed at the bottom of the bottom plate, a stove door detachably installed on the front of the main frame, two air inlets detachably installed on the front of the main frame, an ash collection box detachably installed on the front of the main frame, at least one threaded cylinder fixedly installed on the front and back of the main frame, at least one air inlet installed on the two side openings of the main frame, and a smoke exhaust pipe fixedly installed through the top plate, with a heating frame fixedly installed through the middle of the smoke exhaust pipe.

[0006] In a further preferred embodiment, a middle plate is fixedly installed on the inner wall of the main frame, a sealing cap is nested on the top of the copper water tank, a drain pipe is embedded in the bottom of the copper water tank, and the copper water tank is fixedly installed on the inner wall of the main frame.

[0007] More preferably, the threaded cylinder has a threaded post through which the thread passes, and four air inlets are distributed on both sides of the main frame, with the side of the threaded post extending into one side of the air inlet.

[0008] In a further preferred embodiment, the bottom of the exhaust pipe extends through the side of the main frame, the second air inlet plate rests against the top of the faucet, and the threaded column and the air inlet remain parallel.

[0009] More preferably, the top opening of the heating frame is provided with a spiral groove, the copper water tank is located directly above the middle plate, and the front opening of the main frame is provided with an ash discharge port.

[0010] In a further preferred embodiment, a faucet is nested at one end of the drain pipe, a cement furnace is fixedly installed at the top of the middle plate, a wire mesh is nested around the cement furnace, and the drain pipe passes through the cement furnace and extends out of the front of the main frame.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1 to 3A cement furnace chamber for a stainless steel wood-fired stove includes a main frame 1 and a top plate 2 fixedly installed on its top. The inner wall of the main frame 1 is provided with heat insulation filling 23. A ash collection box 6 is fixedly installed at the bottom of the main frame 1. Multiple casters 5 are fixedly installed at the bottom of the ash collection box 6. A stove door 11 is detachably installed on the front of the main frame 1. Two air inlets 3 are detachably installed on the front of the main frame 1. The ash collection box 6 is detachably installed on the front of the main frame 1. At least one threaded cylinder 4 is fixedly installed on the front and back of the main frame 1. At least one air inlet 7 is provided on the openings on both sides of the main frame 1. A flue pipe 8 is fixedly installed through the top plate 2. A heating frame 9 is fixedly installed through the middle of the flue pipe 8.

[0018] Preferably, the threaded cylinder 4 has a threaded post 16 threaded through it, four air inlets 7 are distributed on both sides of the main frame 1, the side of the threaded post 16 extends into one side of the air inlet 7, the bottom of the exhaust pipe 8 passes through the side of the main frame 1, the two air inlet plates 3 abut against the top of the faucet 14, the threaded post 16 and the air inlet 7 are kept parallel, the top opening of the heating frame 9 is provided with a spiral groove, the copper water tank 17 is located directly above the middle plate 19, and the front opening of the main frame 1 is provided with an ash discharge port.

[0019] In practice, the threaded post 16 is blocked on the side of the air inlet 7, and two threaded posts 16 are located on the side of one air inlet 7. Air enters the main frame 1 through the gap between the groove on the surface of the threaded post 16 and the edge of the air inlet 7, allowing the air to slowly enter the main frame 1. The firewood inside the main frame 1 burns slowly, thereby adjusting the combustion efficiency and temperature of the firewood. By rotating the threaded post 16 to move it in the threaded cylinder 4, the overlap length between the threaded post 16 and the air inlet 7 is reduced, allowing air to enter the main frame 1 through the air inlet 7. The overlap length between the threaded post 16 and the air inlet 7 can be adjusted, thereby adjusting the flow rate of air entering the main frame 1 and adjusting the combustion efficiency of the firewood.

[0020] Preferably, a faucet 14 is nested at one end of the drain pipe 18, a cement furnace 21 is fixedly installed on the top of the intermediate plate 19, a wire mesh 22 is nested around the cement furnace 21, the drain pipe 18 passes through the cement furnace 21 and extends out of the front of the main frame 1, the intermediate plate 19 is fixedly installed on the inner wall of the main frame 1, a sealing cover 10 is nested at the top of the copper water tank 17, the drain pipe 18 is embedded at the bottom of the copper water tank 17, and the copper water tank 17 is fixedly installed on the inner wall of the main frame 1.

[0021] In practice, the wire mesh 22 is wrapped around the perimeter of the cement furnace 21, and then cement is applied to the perimeter of the cement furnace 21 to wrap the wire mesh 22. The thickness of the cement is about three centimeters to prevent the wire mesh 22 from oxidizing and rusting at high temperatures. The drain pipe 18 passes through the cement furnace 21 and comes into direct contact with the flame, so that the drain pipe 18 is heated inside the cement furnace 21, which can heat the hot water inside the copper water tank 17.

[0022] In use, the following steps are taken: First, open the stove door 11 and place firewood on the grid 20 of the cement furnace chamber 21. Then, close the stove door 11. The firewood burns on the grid 20 inside the main frame 1. Air enters the main frame 1 through the gap between the groove on the surface of the threaded column 16 and the edge of the air inlet 7, causing the firewood to burn slowly on the grid 20 inside the main frame 1. The smoke from the firewood combustion is discharged from the main frame 1 through the exhaust pipe 8. When it is necessary to increase the firewood combustion temperature, rotate the threaded column 16 to move it in the threaded cylinder 4. The length of overlap between the threaded column 16 and the air inlet 7 is reduced, thereby allowing air to enter the main frame 1 through the air inlet 7, greatly increasing the amount of air entering the main frame 1, so that the firewood burns fully inside the main frame 1. The temperature rises as the firewood burns fully. After the firewood has finished burning, the ash produced falls through the grid 20 into the ash collection box 6.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
