[0016] The present invention is further described below in conjunction with the embodiments and drawings, but the present invention is not limited to the following embodiments, and it can be foreseen that various changes may occur in the implementation by those skilled in the art in combination with the prior art.

[0017] like Figure 1-3 The utility model provides an energy-saving stove, comprising a panel 1, a pot 2, a stove body 3 and an exhaust port 7; the stove body 3 is cylindrical, the stove body 3 is provided with a panel 1, and a flat ring is provided on the edge of the pot 2, so that the pot 2 is buckled on the panel 1, and the lower end of the stove body 3 is provided with a universal wheel 13 with a brake pedal, firstly, it is convenient to clean the stove body 3 after the overall movement, and secondly, it is convenient for fresh air to enter the stove body 3 to ensure that the fuel can be fully burned; a stove core tube 5 and a stove core cover tube 6 are provided in the stove body 3, the stove core tube 5 is sleeved in the stove core cover tube 6, the height of the stove core cover tube 6 is higher than the stove core tube 5, and an oxygen supply area is provided between the stove core tube 5 and the stove core cover tube 6, so as to improve the utilization rate of the heat generated by the fuel combustion, so that the fuel can be fully burned in the stove body 3, and the generated heat can be retained in the stove body 3 for a long time, thereby effectively avoiding most of the heat from being discharged with the exhaust port 7, and reducing the heat loss.

[0018] The height of the furnace body 3 is higher than that of the furnace core cover tube 6. The furnace core cover tube 6 contacts the bottom of the pot 2, and a flat ring is provided on the edge of the pot 2, so that the pot 2 is buckled on the panel 1, ensuring that the bottom end of the pot 2 can contact the outer flame generated by the combustion of the fuel, rather than the middle flame or the inner flame, thereby reducing the heat loss after the combustion of the fuel and improving its utilization rate; an air guide port 8 is provided at the upper end of the furnace core cover tube 6, and the air guide port 8 is arranged on the side away from the exhaust port 7. The size of the air guide port 8 is 1 / 6-1 / 5 of the circumference of the furnace core cover tube 6. The height of the opening end of the furnace core cover tube 6 is higher than the height of the furnace core tube 5. When air enters the furnace body 3, the heat transfer between the furnace core tube 5 and the furnace core cover tube 6 will cause the air entering the furnace body to move upward due to the heat. After fully burning and reacting after meeting the flame at the upper end of the furnace core tube 5, the air moves toward the air guide port 8, so that it moves unidirectionally in the furnace body 3, thereby improving the retention time of heat in the furnace body 3, thereby increasing the utilization rate of heat.

[0019] The energy-saving stove of the present application is arranged through a multi-layer cylindrical structure, which can effectively avoid safety hazards such as overheating of the outer wall of the furnace body 3 during use; an ash box 10 is arranged below the furnace core tube 5 for collecting dust generated by the complete combustion of the upper fuel, and a combustion plate 11 is arranged at the bottom end of the furnace core tube 5. The combustion plate 11 is in a downward curved arc shape, and a plurality of ash holes are arranged on the combustion plate 11, and the ash holes also play the role of oxygen supply. An air inlet is arranged between the furnace core tube 5 and the ash box 10 corresponding to the combustion plate 11, so that the bottom end of the fuel can contact with sufficient air when burning in the furnace body 3, thereby achieving the fuel Full combustion, thereby saving fuel; the bottom surface of the furnace body 3 is provided with air holes 9 corresponding to the oxygen supply area, which provides sufficient oxygen for the fuel in the furnace body 3 so that it can be fully burned, thereby maximizing the use of the fuel; the furnace body 3 is provided with a fuel addition port 4, one end of the fuel addition port 4 is provided with a door 12, and the other end passes through the furnace core cover tube 6 and is connected to the furnace core tube 5, so that the fuel is burned in a relatively sealed state, reducing heat loss, while allowing the fuel to be fully burned and increasing the utilization rate of the fuel; a foot pedal can be provided on the furnace body 3, so that when sitting around, the feet can be placed on the foot pedal to improve its practicality.

[0020] After the door 12 is opened before operation, fuel is first added into the furnace body 3, and the exhaust situation of the exhaust port 7 is observed. At the same time, the panel 1 is touched by hand or the hand is suspended above the pot 2 to feel whether there is temperature, and whether the heat transfer is stable. After observing the fuel combustion situation in the furnace body 3 through the fuel adding port 4, the door 12 is closed, and then cooking and frying are performed with the pot 2 to meet the needs of life; fresh air will enter the furnace body 3 through the air holes 9 arranged on the bottom surface of the furnace body 3 corresponding to the furnace core cover tube 6, providing sufficient oxygen for the fuel in the furnace body 3, so that it can be fully burned, thereby maximizing the use of fuel; when air enters the furnace body 3, the heat transfer between the furnace core tube 5 and the furnace core cover tube 6 will cause the air entering the furnace body to be heated and move upward, and after fully burning and reacting after meeting the flame at the upper end of the furnace core tube 5, it will move to the air guide port 8, so that it makes a unidirectional movement in the furnace body 3, thereby increasing the retention time of heat in the furnace body 3, thereby increasing the utilization rate of heat; the utility model effectively solves the problem that the heat utilization rate of the existing stoves is low and the heat cannot be effectively transferred to the pot.
