DETAILED DESCRIPTION

[0027] The utility model will be further described in combination with specific embodiments.

[0028] As Figure 1 and Figure 2 Indicated, the outdoor burner of the utility model, first including a shell 1, the vertical section of the shell 1 is inverted trapezoidal, in other embodiments, the shell 1 can also be other regular or irregular, symmetrical or asymmetric shape.

[0029] The position close to the bottom of the front and rear two sides of the shell 1 can be seen, here is provided with several long strip-shaped smoke exhaust holes 2, the plurality of smoke exhaust holes 2 on each surface is distributed in the form of fan, is arranged in the side portion specially for discharging the smoke generated by combustion in the shell 1.

[0030] Second air hole 3 is provided on one side of shell 1, second air hole 3 is much larger than smoke exhaust hole 2, effectively guarantees the overall air permeability, can ensure that the oxygen is sufficient when burning in shell 1.

[0031] On the top surface of the shell 1, a connecting pipe 4 can be seen through the shell 1, a plurality of leakage holes 41 of different shapes are provided on the outer circumferential surface of the connecting pipe 4.In the interior of the shell 1, the bottom of the connecting pipe 4 is connected with the combustion pipe 5, the combustion pipe 5 is coaxial with the connecting pipe 4, a baffle 51 filled with the inner diameter of the combustion pipe 5 is arranged in the combustion pipe 5 close to the bottom thereof, the combustion pipe 5 is simultaneously connected with the branch pipe 6 below the baffle 51, the bottom of the branch pipe 6 is provided with the base 9, the bottom surface of the shell 1 is matched with the shape and size of the base 10, can just match the outer contour of the base 10 and connect.The top end of the branch pipe 6 extends into the interior of the combustion pipe 5, the branch pipe 6 as the main component of supporting the combustion pipe 5 and the connecting pipe 4 is fixedly connected with the bottom surface of the shell 1.In addition, as Figure 2 and 3As shown, the top of the connecting pipe 4 is also provided with a guide 11, which is also cylindrical in shape as a whole, and includes a vertical guide hole 12 in the middle, and four guide plates 13 are arranged in a circumferential array outside the vertical guide hole 12, so that when the flame flows out of the guide 11 upward, it can change from vertical upward to spiral upward under the action of the guide plates 13, thereby further improving the user's experience and being more beautiful.

[0032] Further, the combustion pipe 5 is connected with the inclined downward feeding pipe 7 and the air pipe 8 at the side, the top surface of the feeding pipe 7 is flush with the top surface of the shell 1, which not only ensures the beauty of the overall structure, but also facilitates the disassembly and assembly of the overall structure. Specifically, the shell 1, the downward feeding pipe 7, the combustion pipe 5 and the air pipe 8 can be designed as an integral molding, so that the user only needs to lift the shell 1 together with the components to clean the inside of the combustion pipe 5 and the air pipe 8 and the downward feeding pipe 7, or to clean the ash of the base 9.

[0033] It should be noted that in the present embodiment, the axis of the branch pipe 6 is also the symmetry axis of the shell 1, which can ensure the stability of the overall structure, and based on the requirements of beauty, volume and other aspects, due to the presence of the downward feeding pipe 7, the combustion pipe 5 and the connecting pipe 4 are not necessarily coaxial with the branch pipe 6.

[0034] The air pipe 8 horizontally faces the inside of the shell 1, and the fuel for combustion falls on the baffle 51 after being fed from the downward feeding pipe 7 for combustion, the air pipe 8 ensures sufficient oxygen on the one hand, and can guide the smoke on the other hand, and controls the stable and sequential discharge of the flue gas. A plurality of first air holes 52 are provided on the baffle 51, which can satisfy sufficient gas exchange and realize sufficient combustion.

[0035] The glass pipe 10 is detachably connected to the top of the connecting pipe 4, and the connecting pipe 4 and the combustion pipe 5 can also be detachably connected, so that the user can adjust the height of the glass pipe 10 and the height of the connecting pipe 4 according to his own needs, or can disassemble the pipe body for cleaning and replacement.

[0036] Overall, the present scheme uses the connecting pipe 4 engraved with the leakage hole 41 to improve the user experience of the outdoor burner, the shape of the leakage hole 41 can be mapped to the ground to form an aesthetic light spot during combustion; at the same time, the design of the air pipe 8 and the smoke exhaust hole 2 can improve the overall smoke exhaust performance, and the design of the shell 1 and the base 9 can improve the stability of the whole, and is less likely to occur during use.
