[0036] The top of bottom shell 100 forms the opening, and the devices fixed inside bottom shell 200, such as combustor 300, can be put into or taken out of bottom shell 100 through the opening. One side of upper cover 200 is rotatably connected with bottom shell 100, so that upper cover 200 can rotate relative to bottom shell 100. Upper cover 200 can be rotated to an open state and a closed state.

[0037] As shown in the figure, when upper cover 200 is in the closed state, stove head assembly 400 is located directly above combustor, and stove head assembly 400 can guide the flame to flow upward to better heat the pot and wait for the heating object, so that the user can normally use the alcohol stove of the embodiment. As shown in the figure, when upper cover 200 is in the open state, bottom shell 100 is open, and combustor 300 in bottom shell 100 can be exposed, so that the user can add alcohol fuel to combustor 300 without disassembling bottom shell 100, which is more simple to operate and more convenient to use. Figure 1 Figure 3 In some embodiments, as shown in the figures, combustor 300 includes combustion furnace 310, top cover 320, mesh plate 330 and alcohol cotton 340. Combustion furnace 310 is used to load alcohol fuel, alcohol cotton 340 is placed in combustion furnace 310, and top cover 320 is detachably covered on combustion furnace 310. When the user needs to add alcohol to combustion furnace 310, top cover 320 can be opened, and alcohol is placed in combustion furnace 310, so that the user can add alcohol more simply, which further facilitates the use of the user.

[0038] In some embodiments, as shown in the figures, combustor 300 includes combustion furnace 310, top cover 320, mesh plate 330 and alcohol cotton 340. Combustion furnace 310 is used to load alcohol fuel, alcohol cotton 340 is placed in combustion furnace 310, and top cover 320 is detachably covered on combustion furnace 310. When the user needs to add alcohol to combustion furnace 310, top cover 320 can be opened, and alcohol is placed in combustion furnace 310, so that the user can add alcohol more simply, which further facilitates the use of the user. Figure 3 Figure 4

[0039] ​​​​The top cover 320 is provided with a through-going combustion port 321, and a mesh plate 330 is fixed to the bottom surface of the top cover 320 and covers the combustion port 321. The volatilized alcohol can pass through the mesh plate 330 and the combustion port 321, and a flame can be formed after ignition, so that the alcohol can be continuously combusted.

[0040] In this embodiment, the inner diameter of the top cover 320 can be slightly smaller than the outer diameter of the combustion furnace 310, so that the top cover 320 is tightly clamped on the outside of the combustion furnace 310, and the detachable cover is arranged on the combustion furnace 310. Of course, other detachable connection modes such as buckle connection and threaded connection can also be used.

[0041] In some embodiments, as shown in Figs. 1 and 2, the burner head assembly comprises a vertically arranged ignition tube 410, which is arranged in the opening 201, and the inner diameter of the ignition tube 410 gradually decreases in the upward direction. Figure 5 and Figure 6 The flame generated by the combustion of the burner enters the ignition tube 410 from the lower end of the ignition tube 410 and flows upward in the ignition tube 410, forming a "chimney effect" and helping to increase the fire. At the same time, since the inner diameter of the ignition tube 410 gradually decreases in the upward direction, the flame will relatively concentrate upward, concentrating the heating of the pot and avoiding heat loss caused by random swinging of the flame, thereby improving the thermal efficiency.

[0042] The ignition tube 410 can be directly fixed to the upper cover 200 or fixed to the upper cover 200 through an intermediate connecting piece.

[0043] Further, the burner head assembly further comprises a support plate 420, which is provided with a through-going ignition hole, the lower end of the ignition tube 410 is fixed to the support plate 420, and the ignition hole is located on the inner side of the ignition tube 410. The flame first passes through the ignition hole and then enters the ignition tube 410. The support plate 420 plays a role of supporting and fixing the ignition tube 410.

[0044] In this embodiment, the lower end of the ignition tube 410 can be welded to the support plate 420, or can be fixed to the support plate 420 by other means such as clamping, threaded connection, screw fixing, etc.

[0045] Further, the burner head assembly further comprises a bracket 430, which is fixed to the bottom surface of the upper cover 200, the bracket 430 is provided with a fire-through hole 431 which is in abutment with the opening 201, and the support plate 420 is fixed to the bracket 430. The bracket 430 supports and fixes the support plate 420 and the ignition tube 410. The flame generated by the burner passes through the fire-through hole 431 and the ignition hole, and then enters the ignition tube 410.

[0046] The bracket 430 can include a bottom plate and two side plates, the lower ends of the two side plates are connected to the two sides of the bottom plate respectively, the upper ends of the two side plates are connected to the upper cover 200, and the whole has a "N" shape structure, so that the bottom plate is spaced apart from the upper cover 200 by a certain distance, and space is provided for the installation of the support plate 420 and the firecracker 410. The support plate 420 can be fixed on the top surface of the bottom plate.

[0047] The periphery of the support plate 420 can be provided with a plurality of supporting feet, and the supporting feet are fixedly connected to the bracket 430 by welding, screw fixing or the like.

[0048] In some embodiments, as shown in Figure 1 , Figure 5 and Figure 6 , the bracket 430 is provided with a fire adjusting cover 441 and a fire adjusting rod 442, the middle part of the fire adjusting rod 442 is rotatably connected to the bracket 430, and one end of the fire adjusting rod 442 is connected to the fire adjusting cover 441. When the user rotates the fire adjusting rod 442, the fire adjusting cover 441 can be correspondingly rotated.

[0049] The fire adjusting cover 441 can be rotated to cover the fire hole 431 or open the fire hole 431. During the rotation of the fire adjusting rod 442 relative to the bracket 430, the fire adjusting cover 441 can change the area of the fire hole 431. Since the flame flows upward through the fire hole 431, the larger the area of the fire hole 431, the larger the flame that can pass through, and the stronger the corresponding firepower. Conversely, the smaller the area of the fire hole 431, the smaller the flame that can pass through, and the weaker the corresponding firepower. Therefore, the size of the firepower can be changed by rotating the fire adjusting rod 442 in this embodiment, so that the user can select the firepower that matches the cooking demand, further facilitating the use of the user.

[0050] Further, the upper cover 200 can be provided with a through slot 202, and the end of the fire adjusting rod 442 away from the fire adjusting cover 441 can extend out of the upper cover 200 through the through slot 202. In this way, the user can directly operate the fire adjusting rod 442 from the outside without opening the upper cover 200, further facilitating the use of the user.

[0051] In some embodiments, as shown in Figure 6 and Figure 7 , the burner assembly further includes a fire divider 450, which is arranged above the firecracker 410 and is used to disperse the flame. The flame passing through the firecracker 410 is relatively concentrated, and the flame that is too concentrated only heats the local position of the pot, which is not conducive to the uniform heating of the pot. Therefore, the flame is dispersed into multiple streams by the fire divider 450 in this embodiment, so as to heat multiple positions of the pot, thereby avoiding that the local position of the pot is heated too high, and the food or water in the pot is heated uniformly.

[0052] Further, the fire distributor 450 comprises a fire plate 451, the bottom of the fire plate 451 is provided with a circular truncated cone-shaped protrusion 452, in the downward direction, the outer diameter of the protrusion 452 gradually decreases, after the flame contacts the protrusion 452, the flame will move upwards along the outer periphery of the protrusion 452, and then gradually spread to the four directions, and the spread flame will move upwards from the outer periphery of the fire plate 451 to further spread the flame.

[0053] The periphery of the fire plate 451 can be provided with a plurality of fire distribution tabs, the fire distribution tabs can be uniformly and symmetrically distributed relative to the axis of the protrusion 452, and the flame can pass between adjacent fire distribution tabs, which can improve the fire distribution effect and make the flame spread more evenly.

[0054] The fire distribution tabs can be circular arc-shaped, triangular or other relatively regular shapes.

[0055] Further, the fire distributor 450 further comprises two supports 453, the two supports 453 are respectively connected to the two sides of the fire plate 451, and the lower end of the support 453 can be fixed on the upper cover 200 to stably install the fire distributor 450 and ensure that the fire distributor 450 is above the fire lance 410.

[0056] In some embodiments, as shown in Figs. Figure 1 , Figure 6 and Figure 8 The top surface of the upper cover 200 is fixed with a pot rack 500 and a baffle 600, the pot rack 500 is used to support the pot, and the baffle 600 is arranged outside the pot rack 500, and the baffle 600 mainly plays a windproof role to avoid the wind blowing out the flame of the burner, which is especially suitable for outdoor use of the alcohol stove. The baffle 600 can be annular, and the pot rack 500 and the fire lance 410 are arranged inside the baffle 600. At the same time, since the pot rack 500 and the baffle 600 are fixed on the upper cover 200, the pot rack 500 and the baffle 600 will not fall off during the rotation of the upper cover 200.

[0057] Further, the top surface of the upper cover 200 is provided with a sink 202 matched with the baffle 600, the lower end of the baffle 600 is located in the sink 202, and the sink 202 is used to limit the movement of the baffle 600 and position the lower end of the baffle 600. The pot rack 500 comprises a plurality of pot feet 510, the pot feet 510 are used to support the pot, and the pot feet 510 comprise a limiting portion 511 extending above the baffle 600, the bottom surface of the limiting portion 511 is provided with a limiting groove 512, and the upper end of the baffle 600 is inserted into the limiting groove 512, and the limiting groove 512 is used to limit the movement of the upper end of the baffle 600. Thus, the baffle is fastened on the upper cover 200.

[0058] In the embodiment, the pot rack 500 further comprises a bottom frame 520, and the pot supporting legs 510 are fixed on the bottom frame 520. The bottom frame 520 can be fastened on the upper cover 200 by means of screwing, welding or buckle connection, etc. The bottom frame 520 can be in the shape of a square frame or a circular ring, and correspondingly, the baffle 600 is also in the shape of a square frame or a circular ring.

[0059] In some embodiments, as shown in Figure 1 and Figure 3 the other side of the upper cover 200 (away from the side where the upper cover 200 is rotationally connected with the bottom shell 100) is provided with a buckle 210, and the bottom shell 100 is provided with a buckle position 110 matched with the buckle 210. When the upper cover 200 is in the closed state, the buckle 210 is buckled with the buckle position 110, so as to limit the rotation of the upper cover 200 relative to the bottom shell 100, so that the upper cover 200 can be kept in the closed state, avoiding accidental opening and ensuring normal use of the user. When the user needs to open the upper cover 200, the buckle 210 can be forced to be separated from the buckle position 110, and the buckle 210 no longer limits the rotation of the upper cover 200, so that the upper cover 200 can be normally opened.

[0060] In the embodiment, the buckle position 110 can be a buckle hole matched with the buckle 210, and the buckle 210 is buckled in the buckle hole.

[0061] In some embodiments, as shown in Figure 2 the upper cover 200 can be rotationally connected with the bottom shell 100 through a hinge 220, and of course, the rotationally connected structure can also be realized by means of a hinge or other hinge structure.
