[0032] The present invention provides the following description with reference to the accompanying drawings to assist in a comprehensive understanding of various embodiments of the present invention as defined by the claims and their equivalents. The description includes various specific details to assist in understanding, but these details should be considered as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0033] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0034] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0035] An embodiment of the present invention provides a flip - type alcohol stove, as Figure 1-3 shown, including a bottom shell 100, an upper cover 200, a burner 300 and a stove head assembly 400. The burner 300 is fixed inside the bottom shell 100. The burner 300 can load alcohol fuel and can ignite the alcohol fuel to form a flame. The upper cover 200 is provided with a through - hole. The stove head assembly 400 is fixed on the upper cover 200, so that it can rotate with the upper cover 200, and after the upper cover 200 rotates to a certain angle, the stove head assembly 400 will not fall off. The stove head assembly 400 is also located at the through - hole 201, so that the flame can act on the cookware or other objects to be heated above the upper cover 200 through the stove head assembly 400.

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

[0037] As Figure 1 shown, when the upper cover 200 is in the closed state, the stove head assembly 400 is located directly above the burner. The stove head assembly 400 can guide the flame to flow upward to better heat the cookware or other objects to be heated, so that the user can normally use the alcohol stove of this embodiment. As Figure 3 shown, when the upper cover 200 is in the open state, the bottom shell 100 is open, and the burner 300 inside the bottom shell 100 can be exposed. The user can add alcohol fuel to the burner 300 without disassembling the bottom shell 100, and the operation is simpler and more convenient to use.

[0038] In some embodiments, as Figure 3 and Figure 4 shown, the burner 300 includes a combustion furnace 310, a top cover 320, a mesh plate 330 and an alcohol cotton 340. The combustion furnace 310 is used to load alcohol fuel. The alcohol cotton 340 is placed in the combustion furnace 310, and the top cover 320 is detachably covered on the combustion furnace 310. When the user needs to add alcohol to the combustion furnace 310, the top cover 320 can be opened, and then the alcohol can be placed into the combustion furnace 310. It is simpler for the user to add alcohol, which further facilitates the user's use.

[0039] The top cover 320 is provided with a through - hole combustion port 321. The mesh plate 330 is fixed on 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 after being ignited, a flame can be formed to continuously burn.

[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 fastened to the outside of the combustion furnace 310, and thus can be detachably covered on the combustion furnace 310. Of course, other detachable connection methods such as snap connection and threaded connection can also be adopted.

[0041] In some embodiments, as Figure 5 and Figure 6 shown, the burner assembly includes a vertically arranged flame guide tube 410. The flame guide tube 410 is passed through the opening 201, and in the upward extending direction, the inner diameter of the flame guide tube 410 gradually decreases. The flame generated by the burner enters the flame guide tube 410 from the lower end of the flame guide tube 410 and flows upward in the flame guide tube 410, forming a "chimney effect", which helps to increase the fire intensity. At the same time, since the inner diameter of the flame guide tube 410 gradually decreases in the upward direction, the flame will flow upward relatively concentratedly, heating the cookware intensively, avoiding the random swing of the flame and resulting in heat loss, and improving the thermal efficiency.

[0042] The flame guide tube 410 can be directly fixed on the upper cover 200, or can be fixed on the upper cover 200 through an intermediate connector.

[0043] Furthermore, the burner assembly further includes a support plate 420. The support plate 420 is provided with a through flame guide hole. The lower end of the flame guide tube 410 is fixed on the support plate 420, and the flame guide hole is located inside the flame guide tube 410. The flame first passes through the flame guide hole and then enters the flame guide tube 410. The support plate 420 plays a role in supporting and fixing the flame guide tube 410.

[0044] In this embodiment, the lower end of the flame guide tube 410 can be fixed on the support plate 420 by welding, or can be fixed on the support plate 420 by other methods such as clamping, threaded connection, and screw fixing.

[0045] Even further, the burner assembly further includes a bracket 430. The bracket 430 is fixed to the bottom surface of the upper cover 200. The bracket 430 is provided with a fire-passing hole 431 that is docked with the opening 201. The support plate 420 is fixed on the bracket 430. The bracket 430 is used to support and fix the support plate 420 and the flame guide tube 410. The flame generated by the burner passes through the fire-passing hole 431 and the flame guide hole, and then enters the flame guide tube 410.

[0046] The bracket 430 may include a bottom plate and two side plates. The lower ends of the two side plates are respectively connected to both sides of the bottom plate, and the upper ends of the two side plates are both connected to the upper cover 200, presenting an overall "U" - shaped structure, so that the bottom plate is spaced from the upper cover 200 by a certain distance, providing space for the installation of the support plate 420 and the flame guide tube 410. The support plate 420 can be specifically fixed on the top surface of the bottom plate.

[0047] A plurality of support feet can be provided on the periphery of the support plate 420, and the support feet and the bracket 430 are fixedly connected together by welding, screw fixing or other means.

[0048] In some embodiments, such as Figure 1 , Figure 5 and Figure 6 As shown, a fire-adjusting cover 441 and a fire-adjusting rod 442 are provided on the bracket 430. The middle part of the fire-adjusting rod 442 is rotatably connected to the bracket 430. 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 driven to rotate accordingly.

[0049] The fire-adjusting cover 441 can be rotated to cover or open the fire-passing 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-passing hole 431 it covers. Since the flame flows upward through the fire-passing hole 431, the larger the area of the fire-passing hole 431, the larger the flame that can pass through, and the stronger the corresponding firepower. Conversely, the smaller the area of the fire-passing hole 431, the smaller the flame that can pass through, and the weaker the corresponding firepower. Therefore, in this embodiment, the firepower can be changed by rotating the fire-adjusting rod 442 for the user to select a firepower suitable for the cooking needs, further facilitating the user's use.

[0050] Furthermore, a through slot 202 can be provided on the upper cover 200. One 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. Thus, the user can directly operate the fire-adjusting rod 442 from the outside without opening the upper cover 200, further facilitating the user's use.

[0051] In some embodiments, such as Figure 6 and Figure 7 As shown, the burner assembly further includes a flame distributor 450. The flame distributor 450 is arranged above the flame guide tube 410 and is used to disperse the flame. The flame passing through the flame guide tube 410 is relatively concentrated. The overly concentrated flame only heats a local position of the cookware, which is not conducive to the uniform heating of the cookware. For this reason, in this embodiment, the flame distributor 450 disperses the flame into multiple strands to heat multiple positions of the cookware, avoiding excessive local heating of the cookware and uniformly heating the food or water in the cookware.

[0052] Furthermore, the flame distributor 450 includes a flame distribution plate 451. A frustum-shaped protrusion 452 is provided at the bottom of the flame distribution plate 451. In the downward direction, the outer diameter of the protrusion 452 gradually decreases. After the flame contacts the protrusion 452, it will move upward along the outer periphery of the protrusion 452 and then gradually spread around. The spread flame then moves upward from the outer periphery of the flame distribution plate 451 to further disperse the flame.

[0053] The peripheral edge of the flame distributor plate 451 may be provided with a plurality of flame-distributing tabs, which may be evenly and symmetrically distributed relative to the axis of the protrusion 452. The flame can pass through the space between adjacent flame-distributing tabs, which can improve the flame-distributing effect and make the flame spread more evenly.

[0054] The flame-distributing tabs can be arc-shaped, triangular or other relatively regular shapes.

[0055] Furthermore, the flame distributor 450 further includes two brackets 453, which are respectively connected to both sides of the flame distributor plate 451. The lower ends of the brackets 453 can be fixed on the upper cover 200 to stably install the flame distributor 450 and ensure that the flame distributor 450 is above the ignition tube 410.

[0056] In some embodiments, as Figure 1 、 Figure 6 and Figure 8 shown, a pot stand 500 and a baffle 600 are fixed on the top surface of the upper cover 200. The pot stand 500 is used to support the cookware, and the baffle 600 is arranged around the outside of the pot stand 500. The baffle 600 mainly functions to prevent wind from blowing out the flame of the burner, which is especially applicable to using the alcohol stove of this embodiment outdoors. The baffle 600 can be annular and enclose both the pot stand 500 and the ignition tube 410. At the same time, since both the pot stand 500 and the baffle 600 are fixed on the upper cover 200, the pot stand 500 and the baffle 600 will not fall off during the rotation of the upper cover 200.

[0057] Further, a sinking groove 202 adapted to the baffle 600 is provided on the top surface of the upper cover 200, and the lower end of the baffle 600 is located in the sinking groove 202 to limit the movement of the baffle 600 and play a role in positioning the lower end of the baffle 600. The pot stand 500 includes a plurality of pot support feet 510, which are used to support the cookware. The pot support feet 510 include a limiting portion 511 extending above the baffle 600, and a limiting groove 512 is provided on the bottom surface of the limiting portion 511. The upper end of the baffle 600 is inserted into the limiting groove 512 to limit the movement of the upper end of the baffle 600. Thus, the baffle is fastened to the upper cover 200.

[0058] In this embodiment, the pot stand 500 further includes a bottom frame 520. The pot support feet 510 are fixed on the bottom frame 520, and the bottom frame 520 can be fastened to the upper cover 200 in various ways such as screw fixation, welding fixation or snap connection. The bottom frame 520 can be square or circular, and correspondingly, the baffle 600 is also square or circular.

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

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

[0061] In some embodiments, as Figure 2 shown, the upper cover 200 can be rotatably connected to the bottom case 100 through a hinge 220. Of course, it can also be rotatably connected through a hinge or other hinge structures.

[0062] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should clearly understand that the above description of various embodiments of the present invention is only for illustration, rather than for limiting the present invention as defined by the appended claims and their equivalents.
