[0028] The utility model embodiment provides a portable vaporized mixed alcohol stove, combined with Figure 1-9 As shown, it includes a furnace body 1 and a bracket 2 with an annular side wall 27, the bracket 2 is passed through from top to bottom and is detachably connected to the furnace body 1, the outer wall of the furnace body 1 is convexly provided with a limiting portion 11, the lower end of the annular side wall 27 is extended inwardly to be provided with a connecting portion 21, and the connecting portion 21 is abutted and connected with the limiting portion 11; the portable vaporized mixed alcohol stove includes a use state and a storage state, when in the use state, the bracket 2 is supported above the furnace body 1; when in the storage state, the bracket 2 is turned upside down and then sleeved on the furnace body 1.

[0029] like Figure 3 and 8 As shown, when in use, the lower end of the connecting portion 21 abuts against the upper end of the limiting portion 11, and the bracket 2 is in a forward placement state and is installed above the furnace body 1. At this time, the annular side wall 27 plays a role of supporting and increasing the height, and the heated object can be placed above the bracket 2. At the same time, the flame between the heated object and the furnace body 1 is surrounded by the annular side wall 27, which can achieve a windproof effect.

[0030] like Figure 1 As shown, when in the storage state, the original upper end of the connecting portion 21 abuts against the upper end of the limiting portion 11, and the bracket 2 is in a reverse placement state and nested with the furnace body 1 to achieve a good storage effect. The structure is simple, easy to assemble and store, saves space, and is convenient for users to use.

[0031] like Figure 4 and 8 As shown, in this embodiment, the furnace body 1 and the bracket 2 are both approximately barrel-shaped structures, the diameter of the annular side wall 27 is larger than the diameter of the furnace body 1, the limiting portion 11 is circumferentially extended on the outer side of the furnace body 1, and the connecting portion 21 is vertically annularly arranged on the inner side wall of the bracket 2. The limiting portion 11 is matched with the connecting portion 21, and a circular mounting opening 26 is provided at the center of the connecting portion 21, and the diameter of the mounting opening 26 is matched with the diameter of the furnace body 1, so that the furnace body 1 can pass through the mounting opening 26.

[0032] like Figure 6 and 9 As shown, the portable vaporizing mixed alcohol stove also includes a sealing cover 3 covered on the stove body 1, an outer wall of the stove body 1 is provided with an external thread 12, the outer wall of the sealing cover 3 is recessed inward to form an internal thread 31, and the stove body 1 and the sealing cover 3 are detachably connected via the external thread 12 and the internal thread 31.

[0033] Liquid or solid alcohol is placed in the furnace body 1. When the alcohol is ignited, the flame will burn above the furnace body 1. When the sealing cover 3 is placed on the furnace body 1, the oxygen between the sealing cover 3 and the furnace body 1 is burned out, so that the fire can be extinguished. When the sealing cover 3 and the furnace body 1 are connected by threaded sealing, the alcohol can be prevented from spilling, which is convenient for carrying and storage.

[0034] like Figure 2 and 3As shown, the portable vaporizing mixed alcohol stove also includes a fire control ring 4 detachably connected to the sealing cover 3, a card slot 32 is provided on the outer wall of the sealing cover 3, and a buckle portion 41 adapted to the card slot 32 is convexly provided on the inner wall of the fire control ring 4. When the sealing cover 3 and the fire control ring 4 are engaged, the buckle portion 41 is snapped into the card slot 32.

[0035] In this embodiment, the snap-on portion 41 is an arc-shaped protrusion, and the side wall of the fire control ring 4 has a certain elasticity and can produce a slight elastic deformation to facilitate snapping with the sealing cover 3. The inner side wall of the fire control ring 4 is evenly distributed with four snap-on portions 41, and the position of the snap-on portions 41 is matched with the position of the slot 32, so that the fire control ring 4 is snapped on the top of the sealing cover 3, thereby achieving a nested storage effect.

[0036] In this embodiment, the slot 32 is located at the position where the outer wall of the sealing cover 3 is recessed inward, that is, the slot 32 and the internal thread 31 are integrated and dual-purpose, which reduces the step of separately opening the slot 32, thereby saving process, making the structure simpler and reducing costs.

[0037] In other embodiments, the fire control ring 4 and the sealing cover 3 may also be connected by threads.

[0038] like Figure 1 , 4 As shown in Figure 9, the upper end face of the fire control ring 4 is provided with a through fire outlet 42, and the upper end face of the sealing cover 3 is recessed downward to form a pressing portion 33, and the position of the pressing portion 33 is adapted to the position of the fire outlet 42 to facilitate the disassembly between the fire control ring 4 and the sealing cover 3.

[0039] According to the needs of users, the fire control ring 4 can be covered on the furnace body 1 to achieve the effect of reducing the fire power. The area of ​​the fire outlet 42 is smaller than the area of ​​the upper end surface of the fire control ring 4. When the fire control ring 4 is covered on the furnace body 1, it can reduce the air entering the furnace body 1, thereby achieving the effect of reducing the fire power. At the same time, the fire outlet 42 can also make the flame more concentrated.

[0040] The bottom of the fire control ring 4 is circular, and the bottom diameter of the fire control ring 4 is smaller than the diameter of the annular side wall 27 . Therefore, when the cover of the fire control ring 4 is arranged on the furnace body 1 to reduce the fire power, the fire control ring 4 is accommodated in the space surrounded by the annular side wall 27 .

[0041] When it is necessary to separate the sealing cover 3 and the fire control ring 4, the hand or tool can be inserted into the fire outlet 42 to press the pressing part 33 below the fire outlet 42 to make the buckle part 41 disengage from the slot 32, thereby separating the sealing cover 3 from the fire control ring 4.

[0042] The lower end surface of the sealing cover 3 is circular, and the diameter of the lower end surface of the sealing cover 3 is smaller than the diameter of the lower end surface of the fire control ring 4 , so the sealing cover 3 can also be accommodated in the space surrounded by the annular side wall 27 .

[0043] like Figure 1 and 4 As shown, a handle 43 is provided on the fire control ring 4, and the handle 43 is rotatably connected to the upper end surface of the fire control ring 4, and the rotatable angle of the handle 43 is 0-180°.

[0044] When the handle 43 rotates from 0° to 180°, it is a process of changing from the storage state to the use state. In this embodiment, one end of the handle 43 is rotationally fixed to the fire control ring 4, the length of the handle 43 is greater than the diameter of the fire outlet 42, and the length of the handle 43 is less than the cross-sectional diameter of the fire control ring 4, so that the handle 43 can be stored on the fire control ring 4 to reduce the occupied space.

[0045] The handle 43 facilitates the user to cover the fire control ring 4 on the furnace body 1 to reduce the fire power, while reducing the risk of burns caused by the user directly touching the ring body of the fire control ring 4.

[0046] Furthermore, when the fire control ring 4 is snapped together with the sealing cover 3, the user can use the handle 43 to cover the fire control ring 4 and the sealing cover 3 together on the furnace body 1 so that the sealing cover 3 blocks the air above the furnace body 1, thereby achieving a fire extinguishing effect.

[0047] like Figure 4 As shown, a side wall of the bracket 2 is provided with an escape opening 22 opening upward, and the escape opening 22 is suitable for placing the handle 43 .

[0048] When the fire control ring 4 is in use and the user needs to place the fire control ring 4 on the furnace body 1 to adjust the fire power, the handle 43 is inserted from above the escape opening 22 and moved downward. When the user needs to remove the fire control ring 4, the handle 43 is moved upward out of the escape opening 22 to remove the fire control ring 4.

[0049] like Figure 5 and 8As shown, a plurality of rotatable supporting feet 23 are provided at the upper end of the bracket 2, and the supporting feet 23 are used to support the heated object, and the rotatable angle of the supporting feet 23 is 0-270°.

[0050] The support leg 23 is hinged to the support frame and forms a hinge axis. The support leg 23 rotates along the hinge axis. When the support leg 23 rotates from 0° to 270°, it is a process of changing from a storage state to a use state. When the support leg 23 is in use, it can support a heated object, such as a stove.

[0051] In this embodiment, the support legs 23 and the connecting portion 21 are respectively located at the upper and lower ends of the annular side wall 27. There are four support legs 23 evenly distributed at the upper end of the annular side wall 27. The support legs 23 are provided with anti-skid patterns to increase friction and prevent the heated object from sliding. When the anti-skid patterns are close to the inner side wall of the bracket 2, the support legs 23 are in a storage state, and when the anti-skid patterns are nearly parallel to the horizontal plane, the support legs 23 are in a use state.

[0052] In the storage state, the bracket 2 is sleeved on the furnace body 1 , and the supporting legs 23 are accommodated between the annular side wall 27 and the outer side wall of the furnace body 1 .

[0053] like Figure 5-7 As shown, the furnace body 1 is provided with an inner tank 13 with a connected bottom, a capillary channel 131 is formed between the inner tank 13 and the side wall of the furnace body 1, and an air jet 132 is provided on the inner tank 13. When the lower end of the connecting portion 21 abuts against the limiting portion 11, a combustion chamber 24 is formed between the bracket 2 and the furnace body 1, and both ends of the air jet 132 are connected to the capillary channel 131 and the combustion chamber 24 respectively. The bracket 2 is provided with an air inlet 25 connected to the combustion chamber 24.

[0054] In this embodiment, the upper end of the inner liner 13 is fixedly connected to the upper end of the furnace body 1, and liquid alcohol is placed in the inner liner 13. Since the bottom of the inner liner 13 is connected to the furnace body 1, the capillary channel 131 is also connected to the furnace body 1, and the liquid alcohol will enter the capillary channel 131.

[0055] When the liquid alcohol in the inner tank 13 is ignited, the liquid surface of the liquid alcohol burns to generate heat. After the capillary channel 131 is heated, the liquid level in the capillary channel 131 gradually rises and is higher than the liquid level in the inner tank 13. At the same time, the alcohol in the capillary channel 131 is vaporized by heat and ejected from the jet port 132 under the influence of the pressure difference and burns in the combustion chamber 24, thereby obtaining greater combustion power and efficiency, and enabling the alcohol stove to have a good heating effect without affecting the volume.

[0056] The air inlet 25 continuously inhales external air through siphon effect, that is, utilizing pressure difference, and the oxygen in the external air and the alcohol gas are mixed and burned in the combustion chamber 24, further enhancing the combustion effect.

[0057] like Figure 6 and 7 As shown, there are multiple jet ports 132 that are evenly distributed on the upper portion of the peripheral wall of the inner liner 13 , and guide walls 133 are obliquely provided on each of the multiple jet ports 132 . When alcohol gas is ejected from the jet ports 132 , the guide walls 133 provide a guiding function to allow the alcohol gas to be ejected along the peripheral wall of the inner liner 13 .

[0058] When the alcohol gas is ejected along the peripheral wall of the inner tank 13 under the action of the guide wall 133, the flame can be made to present a vortex shape, so that the flame is more concentrated, the heating speed is faster, and the heating effect is better. In addition, the guide wall 133 has a small volume and will not affect the connection between the sealing cover 3 and the furnace body 1. Furthermore, it will not affect the connection between the fire control ring 4 and the furnace body 1.

[0059] like Figure 2 and 3 As shown, a gathering chamber 134 for gathering alcohol gas is provided between the furnace body 1 and the inner tank 13, and the upper and lower ends of the gathering chamber 134 are respectively connected to the capillary channel 131 and the jet port 132, and the interior of the limiting portion 11 is hollow and simultaneously connects the gathering chamber 134 and the capillary channel 131.

[0060] The gathering chamber 134 is formed by the inward depression of the upper part of the outer wall of the inner liner 13. The gathering chamber 134 and the limiting portion 11 can both play the role of gathering alcohol gas, and at the same time, play a buffering role for the spraying of alcohol gas, preventing the alcohol gas from spraying out of the spray port 132 too fast and causing danger.

[0061] Furthermore, the external thread 12 is recessed outward from the inner wall of the furnace body 1, and the side wall of the inner tank 13 is provided with a plurality of convex grooves in a direction away from the side wall of the furnace body 1, so as to further increase the space for alcohol gas to gather and further enhance the buffering effect.

[0062] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
