[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a three-sided viewing window independent wood-burning stove, including a stove body 1, which is the main body for burning wood. A mounting assembly for installing and removing a filter structure is fixedly connected to the top of the stove body 1. The mounting assembly includes a placement plate 3, the bottom of which is fixedly connected to the top of the stove body 1 to provide intermediate transition for the smoke generated during combustion. A filter plate 5 is slidably connected to the inner wall of the placement plate 3 to filter the smoke. A sliding shaft 8 is slidably connected to the outer side of the inner wall of the filter plate 5, allowing the filter plate 5 to be pulled out during installation and removal.
[0034] A sliding shaft 8 is slidably connected to the inner wall of the mounting component, and a fixing box 6 is fixedly connected to the outside of the placement plate 3. The placement plate 3 serves to fix and install the fixing box 6. A sliding box 7 is slidably connected to the inner wall of the fixing box 6, allowing the sliding box 7 to slide out of the inner wall of the fixing box 6. A slider 9 is slidably connected to the inner wall of the sliding box 7, allowing the slider 9 to slide within the inner wall of the sliding box 7. Multiple springs 10 are fixedly connected to the top of the slider 9, causing the springs 10 to move when the slider 9 moves. The other ends of the multiple springs 10 are fixedly connected to the inner wall of the sliding box 7, so that the return of the springs 10 can pull the slider 9 to return to its original position. The outer side of the sliding shaft 8 is slidably connected to the inner wall of the slider 9, so that the slider 9 can lock the sliding shaft 8 in place when it returns to its original position. A flue pipe 4 is fixedly connected to the top of the placement plate 3 for exhausting the last bit of smoke. A treatment window 2 is fixedly connected to the top of the furnace body 1 for maintaining the temperature of the furnace body 1.
[0035] Reference Figure 3 and Figure 4 A combustion plate 11 is fixedly connected to the inner wall of the furnace body 1 for placing wood for combustion. A cleaning plate 12 is slidably connected to the outside of the combustion plate 11, and the sliding of the cleaning plate 12 can clean the outside of the combustion plate 11. A motor 13 is installed at the bottom of the furnace body 1, and a winding shaft 14 is fixedly connected to the drive end of the motor 13. Starting the motor 13 causes the winding shaft 14 to rotate. Two traction ropes 16 are fixedly connected to the outside of the winding shaft 14, and the rotation of the winding shaft 14 causes the two traction ropes 16 to wind up. The other ends of the two traction ropes 16 are fixedly connected to the outside of the cleaning plate 12, and the shortening of the traction ropes 16 can pull the cleaning plate 12 to change position.
[0036] Two sliding shafts 19 are fixedly connected to the other end of the cleaning plate 12. The positional movement of the cleaning plate 12 causes the sliding shafts 19 to move accordingly. A second spring 18 is fixedly connected to the inner wall of each sliding shaft 19. The positional movement of the sliding shaft 19 causes the second spring 18 to deform. Two slides 17 are formed on the inner wall of the furnace body 1. The other end of the second spring 18 is fixedly connected to the inner wall of each slide 17. The reset of the second spring 18 pulls the sliding shaft 19 to reset. Four flexible baffles 15 are fixedly connected to the outside of the cleaning plate 12. The other ends of the four flexible baffles 15 are fixedly connected to the inner wall of the furnace body 1, allowing the flexible baffles 15 to move with the cleaning plate 12, thereby preventing dust from entering the slides 17.
[0037] Working principle: Pull out the filter plate 5 near the middle sliding shaft 8, and slide the sliding box 7 to move the slider 9 away from the inner wall of the fixed box 6. Then the filter plate 5 can be pulled out by sliding. During installation, the filter plate 5 needs to be placed on the inner wall of the placement plate 3, and then the sliding box 7 is placed on the inner wall of the fixed box 6. Move the slider 9 so that the groove of the slider 9 is aligned with the groove of the sliding box 7. Slide the sliding shaft 8 into the inner wall of the filter plate 5, and then remove the external force. The return of the spring 10 can drive the slider 9 to lock the sliding shaft 8, thereby fixing the position of the sliding shaft 8 and fixing the position of the filter plate 5. This allows the wood-burning stove to have a filter structure at the flue gas outlet that is easy to replace. It can efficiently filter harmful substances in the flue gas, protect the environment and human health. The easy replacement design ensures the continuity and stability of the filtration effect, bringing users a safer and more comfortable user experience.
[0038] After burning for a period of time, a large amount of dust will accumulate on the top of the combustion plate 11. The accumulated dust cannot fall through the mesh. The motor 13 is started, and the rotation of the drive end of the motor 13 drives the winding shaft 14 to rotate. The rotation of the winding shaft 14 can wind up the two traction ropes 16. The traction ropes 16 can pull the cleaning plate 12 to change position, thereby cleaning the combustion plate 11. The position change of the cleaning plate 12 can also drive the two sliding shafts 19 to change position. The position change of the sliding shafts 19 causes the second spring 18 to deform. After the traction force of the traction ropes 16 is removed, the cleaning plate 12 can be reset under the condition of the second spring 18, preparing for the next ash cleaning. During the movement of the cleaning plate 12, the flexible baffles 15 on both sides can move with it, keeping the inner wall of the slide 17 clean. Timely cleaning of the large amount of wood ash produced by burning wood in the wood-burning stove can prevent the wood ash from affecting the combustion efficiency, avoid uneven heat distribution caused by uneven heating of the flame, reduce the emission of harmful gases, protect indoor air quality, extend the service life of the equipment, and ensure safe use.
