[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Refer to Figures 1-5 For an embodiment of the present invention, it discloses an outdoor multi-functional smokeless stove, which is used to connect with a warm air blower. The high-temperature tail gas generated by the warm air blower is used to achieve smokeless heating of the cookware 2. Specifically, the stove includes:

[0029] A furnace body 1 having a first flue 11 and a second flue 12;

[0030] An upper support assembly 3 for connecting an external heat source and supporting the cookware 2 is arranged in the first flue 11, and a lower support assembly 4 for supporting the cookware 2 is arranged in the second flue 12. The first flue 11 and the second flue 12 are rotated by the furnace body 1 to realize the switching of the support and working states, that is, in this embodiment, by adopting the upper support assembly 3 and the lower support assembly 4, separate heating operations can be carried out at both ends of the furnace body 1 to meet the multi-functional outdoor use requirements.

[0031] In some embodiments, in this embodiment, the first flue 11 and the second flue 12 are symmetrically formed inside the furnace body 1 respectively and penetrate through both ends of the furnace body 1 to form openings. In this embodiment, the columnar furnace body 1 is taken as an example. Of course, in other embodiments, the furnace body 1 can also be set in a rectangular shape, that is, a furnace body 1 structure with two support surfaces, which are all covered in the protection scope of the present invention. During actual use, by rotating the furnace body 1, one of the first flue 11 or the second flue 12 is in a working state, that is, heating the cookware 2, and the other is used as a support for supporting on the ground.

[0032] Furthermore, the operation of the upper support assembly 3 in the first flue 11 will be described as follows. It should be noted that during this process, the opening of the second flue 12 supports on the ground. In this embodiment, the upper support assembly 3 includes a heat collection box 31 fixed to the opening side of the first flue 11. The top of the heat collection box 31 is designed to be open, and a partition board 32 is fixedly installed inside the heat collection box 31;

[0033] Wherein, a heat conduction tube 33 is fixedly installed on the outer side of the furnace body 1, and one end of the heat conduction tube 33 communicates with and is connected to the partition plate 32.

[0034] On the basis of the above embodiment, in this embodiment, an insertion tube 34 for connecting a heat source is inserted at the inlet of the heat conduction tube 33. A sleeve 35 is fixedly installed on the outer side of the insertion tube 34. The function of the sleeve 35 is to limit the insertion position. In this embodiment, the sleeve 35 is preferably fixed to the outer side of the insertion tube 34 by bolts to achieve adjustable position. When specifically connecting, one end of the insertion tube 34 is inserted into the tail gas discharge port of the air heater, guiding the high-temperature tail gas into the heat conduction tube 33 to achieve smokeless heating of the cookware 2. Of course, the position of the sleeve 35 can also be adaptively adjusted according to the requirement of the insertion depth to control the insertion depth.

[0035] In addition, in this embodiment, a plurality of air return holes 36 are further opened on the end face of the partition plate 32. An exhaust pipe 37 communicating with the heat collection box 31 is further fixedly installed on the outer side of the furnace body 1. The air return holes 36 are evenly distributed on the partition plate 32. After the cookware 2 is heated, the waste heat gas flows downward along the air return holes 36 and returns to the heat collection box 31, and then can be discharged outward through the exhaust pipe 37.

[0036] Preferably, on the basis of the above solution, a muffler 38 is movably inserted at the outer end of the exhaust pipe 37, and an extension pipe 39 is further installed at the output end of the muffler 38. The structure of the muffler 38 is prior art and will not be elaborated here. Its design purpose is to reduce the exhaust noise of the furnace body 1. Among them, the design of using the extension pipe 39 can achieve the effect of increasing the smoke exhaust channel. The length of the extension pipe 39 can be changed according to actual needs, and there is no technical obstacle for those skilled in the art, so it will not be elaborated here.

[0037] The above description specifically describes the working state of the upper support assembly 3 in the first flue 11. Further, the working state of the lower support assembly 4 will be described in detail below. It should be noted that in this state, the opening side of the first flue 11 is used to support the ground;

[0038] Specifically, in this embodiment, the lower support assembly 4 includes a support plate 41 fixed in the second flue 12, and a plurality of support claws 42 are further fixed inside the second flue 12. In this embodiment, the design of using the support plate 41 is to place the alcohol box. When specifically working, the furnace body 1 is turned 180 degrees so that the second flue 12 faces upward. At this time, the alcohol box can be placed on the support plate 41 and ignited, and the cookware 2 can be placed on the plurality of support claws 42. At this time, the entire furnace body 1 can be switched to the working state of an alcohol stove to meet the multi-functional use requirements.

[0039] On the basis of the above embodiments, in this embodiment, a plurality of the support claws 42 are circumferentially distributed. Preferably, four support claws 42 are designed in this embodiment, and a continuous stepped notch 421 is formed on the end surface of the support claw 42. The design of the stepped notch 421 is used to meet the usage requirements of cookware with different diameters, that is, by changing the widths of the plurality of stepped notches 421, the stable placement of cookware with different diameters can be satisfied.

[0040] It should be noted that the cookware 2 in this embodiment is a pressure cooker or a fish baking tray. Of course, the cookware 2 in this embodiment is not limited thereto. For example, a soup pot, a steamer, a cooking pot, etc. can also be adapted to this stove, as Figure 5 shown, wherein, the bottom of the fish baking tray has a fitting annular groove 21, which is used to fit with the top edge of the stove body 1 to achieve the effect of being able to place the front or back of the stove body 1.

[0041] In order to achieve better durability, the stove body 1 in this embodiment is made of 304 stainless steel. 304 stainless steel is solid and durable, can achieve more beneficial durability, and can reduce the manufacturing cost, meeting the production requirements.

[0042] In summary, in the present utility model, a warm air blower is used as a heat source, and the smokeless heating operation of the cookware 2 can be realized through the upper support assembly 3. By changing the heat output of the warm air blower, the switching of heating, heat preservation and other modes for the cookware 2 can be satisfied. At the same time, after the stove body 1 is flipped, the lower support assembly 4 can be used as an alcohol stove to meet the multi-functional usage requirements outdoors. The multi-functional flameless cooking solution is perfectly suitable for the forest fire prevention period and meets the different cooking needs of outdoor foodies. While ensuring environmental safety, it also combines practicality and environmental protection concepts.

[0043] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
