The inner fixing plate 11 includes a pot body fixing part 111, a smoke collecting part 112, and a stove core fixing part 113. The pot body fixing part 111, the smoke collecting part 112, and the stove core fixing part 113 are fixedly connected in sequence from top to bottom. The smoke collecting part 112 includes a smoke collecting plate 1121, and the smoke collecting plate 1121 is set to an annular truncated cone structure. The diameter of the end of the smoke collecting plate 1121 facing the stove core fixing part 113 is smaller than the diameter of the end away from the stove core fixing part 113. The stove core fixing part 113 is fixedly connected to the inner edge of the smoke collecting plate 1121. The smoke collecting plate 1121 is provided with a smoke guide hole 1122. The smoke collecting plate 1121 is fixedly connected with a smoke exhaust pipe 1123 which is interconnected with the smoke guide hole 1122. The smoke exhaust pipe 1123 surrounds the outer wall of the stove core fixing part 113, and the smoke exhaust pipe 1123 is located in the heat exchange chamber 13.

[0025] By adopting the above-mentioned technical scheme, the high-temperature flue gas generated when the furnace core is working is gathered in the inner cavity of the stove body 1, and the smoke collecting plate 1121 with an annular frustum structure has a guiding effect on the flue gas, which can make the flue gas flow into the smoke exhaust pipe 1123 more smoothly and quickly, reducing the backflow and accumulation of the flue gas, and can effectively reduce the secondary pollution of the flue gas and the ash accumulation problem inside the furnace, with higher safety, and cold water can be passed into the heat exchange chamber 13 of the furnace, and the waste heat generated by the high-temperature flue gas and the furnace core when working can heat the cold water in the heat exchange chamber 13, so as to achieve the purpose of recycling the waste heat, which can make the utilization rate of the heat generated by the furnace core when working higher, save energy, and be more practical.

[0026] In this embodiment, the smoke guide hole 1122 is configured as an inverted cone structure, and the diameter of the smoke guide hole 1122 at one end facing the stove core fixing portion 113 is smaller than the diameter at the end away from the stove core fixing portion 113, which can further guide the smoke, allowing the smoke to flow into the smoke exhaust pipe 1123 more smoothly and quickly, reducing the backflow and accumulation of the smoke, and allowing the smoke to encounter less resistance when discharged, thereby improving the efficiency of smoke exhaust.

[0027] In this embodiment, the radius difference between the inner and outer edges of the smoke collecting plate 1121 is set to R1, the radius of the smoke guiding hole 1122 is set to R2, R1:R2 is 1:(0.4-0.45), and in this embodiment, R1:R2 is 1:0.43.

[0028] In this embodiment, an anti-slip component 1111 is provided on one side of the inner wall of the pot body fixing part 111, and a gap is provided between the anti-slip component 1111 and the pot body fixing part 111, and a reflector 1112 is abutted against the pot body fixing part 1111 and the anti-slip component 1111. The reflector 1112 fits closely with the pot body fixing part 111 to ensure the stability of the installation of the reflector 1112 and facilitate disassembly and maintenance. The provision of the reflector 1112 can effectively reduce energy loss, improve energy utilization efficiency, and improve heat distribution, so that the heat is more evenly distributed in the furnace body.

[0029] In this embodiment, the pot body fixing portion 111 is configured as an annular truncated cone structure, and the diameter of the pot body fixing portion 111 facing the smoke collecting portion 112 is smaller than the diameter of the end away from the smoke collecting portion 112, so that the reflector 1112 can be installed more stably.

[0030] In this embodiment, a gap is provided between the inner fixing plate 11 and the outer fixing plate 12 , and the heat exchange chamber 13 is formed in the gap between the inner fixing plate 11 and the outer fixing plate 12 .

[0031] In the present embodiment, the heat exchange chamber 13 includes a first heat exchange chamber 131 and a second heat exchange chamber 132. An isolation plate 133 is arranged between the first heat exchange chamber 131 and the second heat exchange chamber 132. The first heat exchange chamber 131 is located between the pot body fixing portion 111 and the outer fixing plate 12, and the smoke exhaust pipe 1123 is located in the second heat exchange chamber 132. In the present embodiment, a layered plate 1311 is arranged in the first heat exchange chamber 131. The layered plate 1311 divides the first heat exchange chamber 131 into two or more layers. An overflow port for liquid circulation is arranged on the layered plate 1311. It should be noted that when the stove core is working, the temperature in the pot body fixing portion 111 is higher than the temperature of the smoke collecting portion 112 and the stove core fixing portion 113. Therefore, the heat exchange chamber 13 is divided into the first heat exchange chamber 131 and the second heat exchange chamber 132. Liquids with different temperature requirements can be heated at the same time, thereby realizing the graded utilization of heat and being more practical.
