[0027] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered 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 invention.
[0028] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0029] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.
[0030] An embodiment of this utility model provides an alcohol stove with a conveniently openable lid, such as... Figure 1-4As shown, the device includes a base shell 100, a top cover 200, and an alcohol container 300. The alcohol container 300 is disposed inside the base shell 100 and is used to hold alcohol. When the alcohol is ignited, it forms a flame. One end of the top cover 200 is rotatably connected to the base shell 100, and the other end is equipped with a switch assembly 400. The top cover 200 can be rotated to a closed state (covering the base shell 100) and an open state (opening the base shell 100). When the top cover 200 is in the open state, the base shell 100 is open, and the user can add alcohol fuel to the alcohol container 300. When the top cover 200 is in the closed state, it covers the base shell 100, allowing the user to use the alcohol stove normally.
[0031] The switch assembly 400 includes a pressing member 410, a hook 420, and an elastic member 430. The hook 420 is connected to the pressing member 410, thus the hook 420 and the pressing member 410 are linked. The hook 420 can be fixed to the pressing member 410, or the hook 420 and the pressing member 410 can be integrally formed. The bottom shell 100 is provided with a locking structure 110 adapted to the hook 420 for hooking. The pressing member 410 is slidably connected to the top cover 200, thus the pressing member 410 can slide relative to the top cover 200. Specifically, the pressing member 410 can slide to a locked state and an unlocked state. The elastic member 430 abuts against the pressing member 410 and applies an elastic force to the pressing member 410 to keep the pressing member 410 in the locked state. When the top cover 200 is closed, if the pressing member 410 is in the locked state, the hook 420 is hooked onto the locking structure 110; if the pressing member 410 is in the unlocked state, the hook 420 is separated from the locking structure 110.
[0032] After the user closes the top cover 200, the elastic element 430 applies an elastic force to the pressing element 410 to keep the pressing element 410 in the locked state. The hook 420 can then remain hooked to the locking structure 110, restricting the opening of the top cover 200 and preventing it from opening on its own. This stabilizes the top cover 200 and ensures normal use of the alcohol stove. When the user needs to open the top cover 200, the user can overcome the elastic force applied to the pressing element 410 by the elastic element 430 and slide the pressing element 410 to the unlocked state. The hook 420 then separates from the locking structure 110, no longer restricting the opening of the top cover 200. The user can then rotate the top cover 200 to facilitate its opening.
[0033] In some embodiments, such as Figure 3 and Figure 4As shown, the side of the upper cover 200 has a through hole 201 penetrating the upper cover 200. The pressing member 410 passes through the through hole 201 and can slide telescopically within the through hole 201. The pressing member 410 can slide telescopically to a locked state and an unlocked state. Because the pressing member 410 passes through the through hole 201, a portion of the pressing member 410 protrudes from the upper cover 200, allowing the user to press the pressing member 410 from the outside of the alcohol stove for convenient operation. At the same time, the through hole 201 guides the sliding of the pressing member 410, ensuring its stable sliding along the telescopic direction.
[0034] Furthermore, a limiting ring 411 is provided on the outer periphery of the pressing member 410. The limiting ring 411 is used to restrict the pressing member 410 from disengaging from the through hole 201, so that the pressing member 410 can remain inserted in the through hole 201 and ensure that the pressing member 410 can be used for a long time.
[0035] In this embodiment, the outer diameter of the limiting ring 411 can be larger than the inner diameter of the through hole 201. The limiting ring 411 is located inside the upper cover 200 and cannot pass through the through hole 201, thereby restricting the pressing member 410 from disengaging from the through hole 201.
[0036] Furthermore, the direction in which the elastic member 430 applies the elastic force to the pressing member 410 is parallel to the direction in which the pressing member 410 extends outward, thereby making it difficult for the pressing member 410 to retract inward and disengage from the perforation 201.
[0037] In some embodiments, such as Figure 2 and Figure 4 As shown, the elastic element 430 is a spring. The axis of the spring is parallel to the direction in which the pressing element 410 slides relative to the upper cover 200. One end of the spring abuts against the pressing element 410. The direction in which the spring applies elastic force to the pressing element 410 is parallel to the direction in which the pressing element 410 slides relative to the upper cover 200, thereby reducing the loss of elastic force and making it easier to keep the pressing element 410 in the locked state.
[0038] Furthermore, the pressing member 410 is also connected to a guide rod 440. The axial direction of the guide rod 440 is parallel to the direction in which the pressing member 410 slides relative to the upper cover 200, and a spring is sleeved on the outside of the guide rod 440. When the pressing member 410 slides relative to the upper cover 200, the guide rod 440 moves along its axial direction, and the spring can still remain sleeved on the outside of the guide rod 440. The guide rod 440 positions the spring, restricting the spring from deflecting in other directions, so that the elastic force it provides remains parallel to the axial direction of the guide rod 440.
[0039] In this embodiment, the other end of the spring can abut against the upper cover 200 or other devices fixed on the upper cover 200, so that the spring can be compressed to apply an elastic force to the pressing member 410. The guide rod 440 can be fixedly connected to the pressing member 410 by various methods such as snap-fit fixing and adhesive fixing, or the pressing member 410 and the guide rod 440 can be integrally formed.
[0040] Of course, in other embodiments, the elastic element 430 may also be a sheet or other device that can provide elastic force.
[0041] In some embodiments, such as Figure 2-4 As shown, a cover plate 450 is also fixed on the inner side of the top cover 200. The cover plate 450 covers the outside of the pressing member 410 and the elastic member 420, which can protect the pressing member 410 and the elastic member 420 from dust and prevent other parts of the alcohol furnace from interfering with the pressing member 410 or the elastic member 420.
[0042] The cover plate 450 is provided with a through groove 451, and the hook 420 is inserted into the through groove 451 and can move in the through groove 451. In this way, the hook 420 can extend out of the cover plate 450 without affecting the hook 420 being hooked on the locking structure.
[0043] Furthermore, the end of the elastic member 430 furthest from the pressing member 410 abuts against the cover plate 450, so that the spring can be compressed to apply an elastic force to the pressing member 410. This eliminates the need for other structures for the elastic member 430 to abut against, simplifying the overall structure.
[0044] The cover plate 450 may also be provided with an opening, in which the guide rod 440 of the above embodiment can be inserted and moved along the opening, which can avoid the guide rod 440 and not affect the movement of the guide rod 440.
[0045] In this embodiment, the cover plate 450 can be integrally formed from a single plate or composed of multiple plates.
[0046] In some embodiments, such as Figure 2 and Figure 5 As shown, the locking structure 110 includes a horizontally arranged locking plate 111 with a through slot 112 into which a hook 420 can be inserted. When the top cover 200 is closed, if the pressing member 410 is in the locked state, the hook 420 is hooked onto the bottom surface of the locking plate 111. After the user operates the pressing member 410, the hook 420 can no longer hook onto the locking plate 111, thus separating from the locking plate 111. When the user opens the top cover 200, the hook 420 can be pulled out from the slot 112.
[0047] Furthermore, the hook 420 has a guide slope 421. During the closing process of the upper cover 200, the locking plate 111 can abut against the guide slope 421. Under the weight of the upper cover 200, the pushing force applied by the locking plate 111 to the hook 420 can overcome the elastic force applied by the elastic member 430 to the pressing member 410, thereby pushing the pressing member 410 to the unlocked state. After the pressing member 410 is in the unlocked state, the hook 420 falls downward. The elastic force applied by the elastic member 430 to the pressing member 410 causes the pressing member 410 to return to the locked state. The locking plate 111 is located above the guide slope 421 of the hook 420, and the hook 420 is then hooked on the bottom surface of the locking plate 111.
[0048] Therefore, when the top cover 200 of this embodiment is closed, its own weight allows the hook 420 to be hooked onto the bottom surface of the locking plate 111, eliminating the need for the user to operate the pressing part 410, making it more convenient to use.
[0049] In this embodiment, the locking structure 110 further includes a vertical plate, which is connected to the locking plate 111 and can be fixed to the inner side of the bottom shell 100. The vertical plate and the locking plate 111 can be in an "L" shape and can be integrally formed.
[0050] In some embodiments, such as Figure 1 and Figure 3 As shown, the top cover 200 is provided with a flame-through opening 210. When the top cover 200 is in the closed state, the flame-through opening 210 is located directly above the alcohol box 300. The flame generated by the combustion of the alcohol box 300 can pass through the flame-through opening 210, thereby heating the pot located above the top cover 200. A pot rack 220 is fixed to the top surface of the top cover 200 to facilitate the placement of the pot.
[0051] Furthermore, the upper cover 200 is also fixed with a flame guiding assembly 240, which is located at the flame passage opening 210. The flame guiding assembly 240 is used to guide the flame and concentrate the fire. Specifically, the flame guiding assembly 240 may include a fire concentrator, which can create a chimney effect, causing the flame to concentrate and flow upward.
[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the edge of the top cover 200 is provided with an upwardly bent flange 230. The flange 230 is relatively smooth and can avoid scratching the user or the bottom shell 100.
[0053] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
