[0016] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0017] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4The utility model provides an embodiment: a combustion-supporting energy-saving core for a wood-fired stove, comprising a stove core outer chamber 7, a stove core inner chamber 8, an extension plate 2 and a primary oxygen inlet channel 5, a stove core bottom ring 9 is fixedly sleeved on the lower side of the inner wall of the stove core inner chamber 8, a stove bridge 6 is fixedly provided on the lower end surface of the stove core bottom ring 9, a retaining ring 1 is fixedly provided on the upper end surfaces of the stove core outer chamber 7 and the stove core inner chamber 8, a sandwich formed between the stove core outer chamber 7 and the stove core inner chamber 8 is a secondary oxygen inlet channel 4, a plurality of secondary oxygen inlet holes 3 are opened on the upper side of the inner wall of the stove core inner chamber 8, and the stove core inner chamber 8, the retaining ring 1 and the stove bridge 6 together form a combustion chamber 10.
[0018] The stove core inner pot 8 is fixedly arranged on the inner side of the stove core outer pot 7, the extension plate 2 is fixedly arranged on the front end surface of the stove core outer pot 7, the secondary oxygen inlet channel 4 is arranged at the lower side of the retaining ring 1 between the stove core outer pot 7 and the stove core inner pot 8, the primary oxygen inlet channel 5 is arranged at the position of the furnace bridge 6, and an interlayer is arranged between the stove core outer pot 7 and the stove core inner pot 8.
[0019] Specifically, when using the energy-saving core, put the energy-saving core into the center of the stove chamber of the firewood stove, and then slide the extension plate 2 so that the extension plate 2 stretches and fits the inner wall of the firewood feeding port, and a stove core bottom ring 9 is provided inside the stove core inner shell 8, and a stove bridge 6 is provided below the stove core bottom ring 9. A plurality of secondary oxygen inlet holes 3 are provided above the inside of the stove core inner shell 8, and a suitable distance is maintained between the stove core inner shell 8 and the stove core outer shell, which is one centimeter. When combustible materials such as firewood burn in the combustion chamber 10, the temperature of the combustion chamber 10 gradually increases with the combustion of the combustible materials, and the heat is rapidly conducted to the interlayer between the inner and outer shells. The temperature in the interlayer rises rapidly, and the volume of the air entering the interlayer increases rapidly and rises rapidly, entering the combustion chamber 10 from the small hole. The air that continuously enters the combustion chamber 10 is high-temperature air and has its own pressure, thereby forming a continuous flow of hot air. High-temperature, high-pressure air entering the center of stove core 8 (combustion chamber 10) through secondary oxygen inlet 3 encounters the incompletely burned black smoke (actually a mixture of soot and carbon monoxide) from the initial cooking process, re-combusting it and releasing even more heat. This secondary oxygen supply and secondary combustion fully releases the calorific value of combustible materials like firewood, resulting in a more intense and high-energy flame. Furthermore, stove core 8 functions both to concentrate fire and heat and to prevent heat from being rapidly dissipated through the chimney. Therefore, the rapidly rising heat is quickly transferred to the pot above the stovetop, where it is utilized as much as possible. This makes cooking more energy-efficient and time-saving than traditional cooking methods, with no backflow of smoke from the stovetop or black smoke from the chimney, making it more environmentally friendly than traditional cooking methods.
[0020] Working principle: When using the energy-saving core, put the firewood into the enclosure mechanism from the firewood mouth. When the firewood, coal and other combustibles burn in the combustion chamber, the temperature of the combustion chamber rises rapidly. The stove core inner pot 8 and the stove core outer pot 7 are both made of steel plates. The temperature gradually rises as the combustibles burn, and the heat is quickly transferred to the interlayer between the inner and outer pots. The upper part of the interlayer is welded and sealed with a retaining ring 1 and the stove core inner pot 8 and the stove core outer pot 7. Two rows of small holes are provided at 1 to 3 cm from the sealing part. When air enters the interlayer, it encounters the heat transferred by the inner and outer pots, and the temperature is radiated. The temperature rises rapidly, the volume increases rapidly, and the air rises rapidly when it encounters high temperature, and enters the combustion chamber from the two rows of secondary oxygen inlet holes 3 on the upper part of the stove core inner pot 8, and its own pressure will generate wind. The high-temperature and high-pressure air entering the center of the stove core inner pot 8 from the secondary oxygen inlet holes 3 encounters the black smoke that was not completely burned the first time (actually a mixture of carbon black and carbon monoxide), and burns the black smoke again. At the same time, part of the carbon dioxide reacts with the carbon black to produce carbon monoxide, and the newly generated carbon monoxide reacts with the high-temperature air that enters for the second time to produce carbon dioxide, which is discharged outdoors through the chimney.
[0021] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
