After the combustion is completed, the cleaning door 10 can be opened to facilitate the cleaning of the slag and ashes at the bottom of the combustion box 1.

[0025] The right end of the rotating rod 6 is fixedly connected to the left end of the rotating handle 8 .

[0026] Through the protection mechanism 3, a protection structure is provided at the feed hopper 2, which can facilitate the addition of fuel and prevent impurities from falling in, thereby making it safer to use. Through the circulation mechanism 4, the fuel added to the feed hopper 2 can be heated and baked, which facilitates the rapid evaporation of moisture in the fuel, so that the fuel entering the combustion box 1 is drier and has a higher temperature, making it easier to ignite.

[0027] like Figure 3-4As shown, the protection mechanism 3 includes a groove 31. The groove 31 is opened on the top right surface of the combustion box 1. A pull rod 32 is movably connected inside the groove 31. A spring 33 is sleeved on the outside of the pull rod 32. A handle 34 is fixedly installed on the right end of the pull rod 32. A movable plate 35 is fixedly connected to the left end of the pull rod 32. A baffle 36 is movably connected inside the feed hopper 2. A through opening 311 is opened through the inner left wall of the groove 31.

[0028] One end of the spring 33 is fixedly connected to the inner right side wall surface of the groove 31 , and the other end is fixedly connected to the right end surface of the movable plate 35 . The movable plate 35 is slidably connected to the inside of the groove 31 .

[0029] The middle of the left end of the movable plate 35 is fixedly connected to the right end of the baffle 36 , the through opening 311 is communicated with the interior of the feed hopper 2 , and the baffle 36 matches the interior of the through opening 311 and is movably connected.

[0030] like Figure 5 As shown, the circulation mechanism 4 includes a filter box 41, the lower end of the filter box 41 is fixedly connected to the top left side of the combustion box 1, a filter screen 42 is fixedly connected inside the filter box 41, a connected air intake pipe 43 is fixedly connected to the top left side of the filter box 41, an air intake valve 44 is fixedly installed on the upper end of the air intake pipe 43, a connected conduit 45 is fixedly installed on the left end of the filter box 41, a control valve 46 is fixedly installed in the middle of the conduit 45, a connected air pump 47 is installed on the right side of the filter box 41, and a connected air outlet pipe 48 is fixedly installed on the right side of the air pump 47.

[0031] The lower end of the guide tube 45 passes through the left side of the combustion box 1 and communicates with the interior of the combustion box 1 .

[0032] The lower end of the air pump 47 is fixedly connected to the top left surface of the combustion box 1 , and the air outlet pipe 48 passes through the left side of the feed hopper 2 and is connected to the inside of the feed hopper 2 .

[0033] When the control valve 46 is closed and the air intake valve 44 is opened, the baffle 36 is pulled outward, and then the air pump 47 is started to suck in external air from the air intake pipe 43 and transport it to the combustion box 1 through the air outlet pipe 48 and the feed hopper 2, so that the oxygen in the combustion box 1 is more sufficient and the combustion is more stable. When the air intake valve 44 is closed and the control valve 46 is opened, the hot air in the combustion box 1 can be transported to the feed hopper 2, so as to facilitate the heating and baking of the fuel on the baffle 36.

[0034] The following is a detailed description of the working principle of the hot air circulation combustion energy-saving equipment.

[0035] like Figure 1-5As shown, when the hot air circulation combustion energy-saving device is in use, fuel can be added into the combustion box 1 through the feed hopper 2, so that the fuel enters the partition net 9 for combustion, and the energy generated when the fuel burns can be transmitted from the heat conduction pipe 5, and the slag and ashes remaining after the fuel burns fall to the bottom of the combustion box 1, and the baffle 36 arranged inside the feed hopper 2 can block the fuel, so that the fuel in the feed hopper 2 accumulates on the baffle 36, and when the fuel is burning, the air pump 47 can be started. After the air pump 47 is started, part of the hot air in the combustion box 1 can be extracted through the conduit 45 and the filter box 41, and the extracted hot air can be transported to the feed hopper 2 through the outlet pipe 48. The hot air entering the feed hopper 2 can heat and bake the fuel on the baffle 36 to quickly evaporate the moisture in the fuel, so that the fuel entering the combustion box 1 is drier and has a higher temperature, which is easier to ignite, and when the dried fuel enters the combustion box 1 for combustion The fuel in the combustion box 1 is not enough, and the handle 34 can be pulled outward, and the handle 34 drives the movable plate 35 and the baffle 36 to move outward through the pull rod 32, and the spring 33 is squeezed at the same time, and then the fuel on the baffle 36 can enter the combustion box 1 through the feed hopper 2. After the addition is completed, the handle 34 is released, and the spring 33 drives the movable plate 35 and the baffle 36 to reset, so that the baffle 36 blocks the fuel again, and at the same time, impurities can be prevented from falling in, which is safer and convenient for adding fuel. At the same time, the turning handle 8 can be rotated, and the turning handle 8 drives the turning rod 6 and the turning plate 7 to rotate, so that the rotating turning plate 7 can stir the fuel to loosen it, avoid fuel accumulation, and then facilitate the full combustion of the fuel, easy operation, and good combustion effect of the equipment.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
