[0031] See also Figure 1-4 The utility model provides a portable outdoor wood stove, including a shell 100, a lower hopper 200 is fixed to the top of the inner wall of the shell 100, an intermediate barrel 101 is fixed at the edge of the bottom surface of the lower hopper 200, a partition plate 700 is fixed to the bottom surface of the intermediate barrel 101, a blower 500 is arranged below the partition plate 700, an air intake connecting pipe 502 is fixed to the output end of the blower 500, one end of the air intake connecting pipe 502 is connected to an air intake guide pipe 501, and the air intake guide pipe 501 passes through the partition plate 700, a furnace 201 is fixed to the bottom of the outer side wall of the lower hopper 200, and a plurality of second air intake holes 301 distributed in a circumference are opened at the bottom of the outer side wall of the furnace 201.

[0032] Further as Figure 2 As shown, a plurality of first air inlet holes 300 distributed in a circumference are opened on the top of the outer wall of the furnace 201 .

[0033] By setting the first air inlet 300, a part of the incompletely burned flue gas in the furnace 201 is mixed with the air injected from the first air inlet 300 and burned again when passing through the top of the furnace 201, thereby making the combustion more complete, improving the thermal efficiency, saving fuel and reducing smoke emissions.

[0034] Further as Figure 3 As shown, the bottom surface of the partition plate 700 is fixed with heat insulating cotton 701 , and the blower 500 is fixed on the bottom surface of the heat insulating cotton 701 .

[0035] By setting the heat insulating cotton 701, the temperature in the intake air can be isolated by the heat insulating cotton 701, thereby preventing heat from entering the lithium battery 401 through the partition plate 700 and causing damage to the lithium battery 401.

[0036] This solution has the following working process: when in use, first add the fuel into the furnace 201 and ignite it, and then operate the control panel 400 to make the lithium battery 401 supply power to the blower 500, drive the blower 500 to rotate at high speed to deliver air, and the air enters the blower 500 and enters the air intake guide pipe 501 through the air intake connecting pipe 502. The air is rotated along the air intake guide pipe 501 to deliver air to the air intake bin, and the rotating air enters the furnace 201 through the first air inlet hole 300 and the second air inlet hole 301 respectively. The air entering the furnace 201 from the second air inlet hole 301 participates in the combustion of the fuel in the furnace 201. When the fuel is burning, a part of the incompletely burned smoke passes through the top of the furnace 201 and is mixed with the air ejected from the first air inlet hole 300 and burns again. When the fuel is burning, the firepower can be controlled by controlling the air volume of the blower 500 through the control panel 400 according to the demand for firepower.

[0037] According to the above working process, it can be known that the entire wood-burning stove is integrated in design by arranging the outer shell 100, the lower hopper 200, the middle barrel 101 and the furnace 201, which is easy to operate and carry.

[0038] By setting the air intake guide pipe 501, the air enters the air intake bin in a rotating manner, and finally enters the furnace 201 in a rotating manner from the second air intake hole 301, so that when the fuel burns below the furnace 201, the incompletely burned smoke passes through the top of the furnace 201 and mixes with the air injected from the first air intake hole 300 and burns again, thereby making the fuel burn more completely, improving thermal efficiency, saving fuel, and reducing smoke emissions.

[0039] By designing the air intake guide pipe 501 as an arc-shaped guide pipe, air can be delivered to the air intake bin along the air intake guide pipe 501, and the air is rotated and sprayed into the furnace 201 from the first air intake hole 300 and the second air intake hole 301, so that when the fuel burns, the flame rotates toward the center and sprays upward, achieving the effect of highly efficient firepower concentration.

[0040] Further as Figure 3 As shown, a bottom plate 102 is fixed to the bottom surface of the shell 100, a lithium battery 401 is fixed to the top surface of the bottom plate 102, a control panel 400 is connected through the bottom of the outer wall of the shell 100, the control panel 400 is electrically connected to the lithium battery 401, and the blower 500 is electrically connected to the control panel 400.

[0041] By setting up the control panel 400, the fire power in the furnace 201 can be controlled by controlling the speed of the blower 500.

[0042] Further as Figure 3 As shown, a furnace head 103 is fixed to the top surface of the housing 100 , a plurality of support plates 600 distributed in a circle are fixed to the top surface of the furnace head 103 , and a plurality of support legs 601 distributed in a circle are fixed to the bottom surface of the bottom plate 102 .

[0043] The supporting feet 601 are provided so that the housing 100 can be supported, thereby facilitating air to pass through the bottom plate 102 .

[0044] Further as Figure 2 As shown, an air intake chamber is formed between the lower hopper 200 and the middle barrel 101 .

[0045] By setting up the air intake bin, the air sucked in by the blower 500 can enter the air intake bin, and then enter the interior of the furnace 201 through the first air intake hole 300 and the second air intake hole 301 .

[0046] In summary: when in use, first add the fuel into the furnace 201 and ignite it, and then operate the control panel 400 so that the lithium battery 401 supplies power to the blower 500, driving the blower 500 to rotate at high speed to deliver air. The air enters the blower 500 and enters the air intake guide pipe 501 through the air intake connecting pipe 502. The air is rotated along the air intake guide pipe 501 to deliver air to the air intake bin. The rotating air enters the furnace 201 through the first air inlet hole 300 and the second air inlet hole 301 respectively. The air entering the furnace 201 from the second air inlet hole 301 participates in the combustion of the fuel in the furnace 201. When the fuel is burning, a part of the incompletely burned smoke passes through the top of the furnace 201 and is mixed with the air ejected from the first air inlet hole 300 and burns again. When the fuel is burning, the firepower can be controlled by controlling the air volume of the blower 500 through the control panel 400 according to the demand for firepower.

[0047] The control panel 400, lithium battery 401, blower 500 and heat insulation cotton 701 can be purchased on the market, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.

[0048] Although the embodiments of the present invention have been shown and described, it is understandable to those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principle and spirit of the present invention, and still fall within the scope of protection of the technical solution of the present invention.
