[0029] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0030] See also Figure 1 This secondary combustion pellet stove splices the front guard plate 1, the rear guard plate 2 and the side guard plate 3 to form a frame structure. The upper end of the cover plate 4 has an opening for heat discharge. The middle part of the pellet rack 5 bulges upward, and there are through holes on the pellet rack 5 to facilitate the air at the bottom of the furnace body to enter the furnace body, facilitating the combustion of pellet fuel. After the fuel is burned, the ash falls freely onto the ash receiving tray 6, which is convenient for ash discharge.
[0031] See also Figure 2 and Figure 4 The diaphragm 7 is a metal plate with air holes at the bottom. The air is introduced into the air passage between the diaphragm 7 and the front guard plate 1, the rear guard plate 2 and the side guard plate 3 through the air holes at the bottom, and the air is discharged into the furnace body through the air permeable portion, thereby improving the combustion quality of the upper part of the furnace body. After the fuel on the particle rack 5 is burned, the tiny particles that rise with the flame and the hot air flow are mixed with the supplementary air at the upper end of the furnace body, and secondary combustion can be carried out, thereby effectively avoiding the generation of smoke and improving the efficiency of particle combustion.
[0032] The ventilation parts on the template 7 are the ventilation windows in the middle and the ventilation holes at the top, which facilitate air to enter the furnace body, and are used to increase the oxygen content in the middle and upper parts of the furnace body, so as to facilitate the secondary combustion of the rising fuel.
[0033] See also Figure 1 The decorative plate 8 is a transfer structure, which can be mounted on the upper ends of the front guard plate 1, the rear guard plate 2 and the side guard plate 3, and is also used for the placement of the cover plate 4. They are all step-shaped structures. The combination of the three is quick and convenient, and the cover plate 4 is also easy to remove and place.
[0034] See also Figure 1 and Figure 2 The hook 9 on the side guard plate 3 can be stuck in the slots on the side walls of the front guard plate 1 and the rear guard plate 2 to complete the splicing. After the splicing, the limiting columns of the telescopic lock buckle 11 are stuck in the through holes on the side walls of the front guard plate 1 and the rear guard plate 2 to complete the locking and prevent the side guard plate 3 from moving up and causing the entire furnace body to fall apart. When disassembling, you only need to pull the telescopic lock buckle 11 to disengage the limiting column from the through hole, lift the side guard plate upward, and the hook 9 can be disengaged from the slot 10 to complete the disassembly.
[0035] See also Figure 2 A support frame 12 is fixed to the side wall of the side guard plate 3 to facilitate the placement of the particle frame 5.
[0036] The inner side of the guide plate 13 is a groove-shaped opening, and the side wall of the ash tray 6 can be stuck in the guide plate 13 to facilitate the sliding of the ash tray 6. There is an opening on the front guard plate 1, the opening size is slightly larger than the size of the ash tray 6, and the opening and the guide plate 13 are located at the same height, so that the ash tray 6 can be extended into the furnace body through the opening and placed in the guide plate 13. There is a handle at the outer end of the ash tray 6, and the handle is exposed to the air. It will not transfer too much heat during the combustion of the fuel and can be held in the hand for use at any time.
[0037] The outer end of the guide plate 13 is folded outward, which plays a certain guiding role when the ash tray 6 is inserted, making it easy to insert. At the same time, the ash tray 6 has an upward convex and concave baffle at the position of the mounting handle. The baffle can be placed on the outside of the opening of the front guard plate 1, which can achieve a certain degree of airtightness and can also limit the maximum moving distance of the ash tray 6.
[0038] The working principle of the utility model is as follows:
[0039] This secondary combustion pellet stove is spliced by splicing the front guard plate 1, the rear guard plate 2 and the side guard plate 3 through the cooperation of the hook 9 and the card slot 10. There are legs between the bottom of the furnace body and the ground to form a gap for air to flow in. The air enters the furnace body, and a part of the air enters directly from the bottom of the pellet rack 5 to provide oxygen for the combustion of the material at the bottom. The other part of the air is introduced through the air duct between the template 7 and the guard plate 1, the rear guard plate 2 and the side guard plate 3. Finally, the air enters the middle and top of the furnace body through the air vents and air holes to supplement the delay for combustion and carry out secondary combustion of the rising tiny particles, which effectively reduces the generation of smoke and improves the combustion efficiency, thereby achieving the purpose of saving fuel.
