Description

Technical Field

[0001] The utility model relates to the field of ovens, in particular to an oven enclosure. Background Art

[0002] In recent years, stoves that help users warm themselves, barbecue, and make tea outdoors (especially in the wild) have become increasingly popular. For example, Chinese utility model patent No. CN221060429U discloses a liftable charcoal stove, which includes a stove body, a charcoal tray and a food rack disposed on the stove body, and a scissor-type lifting device disposed on the stove body. The scissor-type lifting device is used to drive the charcoal tray up and down to adjust the distance between the charcoal tray and the food rack. The scissor-type lifting device includes a lifting device base, a first scissor arm, a second scissor arm, and a lifting rack. The first scissor arm is connected to the lifting device base via a fixed shaft. The lifting device base is provided with a slide rail and a movable shaft. The second scissor arm is connected to the slide rail via a movable shaft. The stove body is provided with a linkage structure, which is implemented as a lever structure and can be moved to at least a first position and a second position. The linkage structure has a handle end and a linkage end, and the linkage end is used to drive the movable shaft of the scissor-type lifting device to move. The stove body is provided with a linkage locking structure for locking the linkage structure, and the linkage locking structure keeps the linkage mechanism in place. The existing lift-adjustable charcoal stove has the following drawbacks: first, after adjusting the distance between the charcoal basin and the food rack by shifting the linkage structure, a special linkage locking structure needs to be used to lock the shifting structure, which results in a complex structure and inconvenient operation of the lift-adjustable charcoal stove. The complex structure not only leads to a high cost of the lift-adjustable charcoal stove, but also results in poor reliability of the lift-adjustable charcoal stove. Second, due to the gravity of the charcoal basin and the charcoal contained in the charcoal basin, when raising the height of the charcoal basin to allow it to move toward the food rack, the closer the charcoal basin is to the food rack, the greater the force the user needs to use to shift the linkage structure. This causes the lift-adjustable charcoal stove to rotate due to lateral force, posing a significant safety hazard. Utility Model Content

[0040] Refer to the attached drawings of the specification of this utility model Figures 1 to 10 In the following description, a stove according to a preferred embodiment of the present invention will be disclosed and explained, wherein the stove includes a stove body 10, a charcoal basin 20, and a lifting device 30. The lifting device 30 includes a hand-cranked mechanism 31 and a lifting mechanism 32. The hand-cranked mechanism 31 is rotatably mounted on the stove body 10. The lifting device 30 is fixedly mounted on the stove body 10 and drivably connected to the hand-cranked mechanism 31. The charcoal basin 20 is supported by the lifting mechanism 32. When a user cranks the hand-cranked mechanism 31, the lifting mechanism 32 can raise and lower the charcoal basin 20, thereby adjusting the height position of the charcoal basin 20.

[0041] Specifically, the hand-crank mechanism 31 has a hand-crank end 311 and a driving end 312 opposite to each other, and the driving end 312 has an external thread. The lifting mechanism 32 includes a base 321, a supporting plate 322, at least one "X"-shaped support arm 323, and a driven portion 324, wherein the support arm 323 has a rotating side 3231 and a sliding side 3232, and the bottom and top of the support arm 323 on the rotating side 3231 are rotatably mounted on the base 321 and the supporting plate 322, respectively, and the bottom and top of the support arm 323 on the sliding side 3232 are slidably mounted on the base 321 and the supporting plate 322, respectively. The support plate 322 is mounted on the base 321 and the support plate 322, such that the support arm 323 supports the support plate 322 above the base 321, wherein the driven portion 324 is rotatably mounted on the support arm 323 at the sliding side 3232 of the support arm 323, and the driven portion 324 has a threaded hole 3241, wherein the base 321 is fixedly mounted on the furnace body 10, and the support plate 322 is used to support the charcoal basin 20. The driving end 312 of the hand-cranked mechanism 311 extends into the threaded hole 3241 of the driven portion 324, and the internal thread of the driven portion 324 is screwed into the external thread of the driving end 312 of the hand-cranked mechanism 31.

[0042] When the user rotates the hand-cranked mechanism 31, the internal thread of the driven part 324 and the external thread of the driving end 312 of the hand-cranked mechanism 31 cooperate with each other to make the driven part 324 move in the horizontal direction. During the movement in the horizontal direction, the driven part 324 can push or pull the support arm 323 to change the posture of the support arm 323 to realize the lifting and lowering of the support plate 322. The charcoal basin 20 rises and falls with the lifting and lowering of the support plate 322, thereby adjusting the height position of the charcoal basin 20.

[0043] In the stove of the present invention, the user can control the lifting of the charcoal basin 20 through the lifting mechanism 32 by manually cranking the hand-cranked mechanism 31. Compared with the prior art charcoal stoves with adjustable lifting and lowering that require the use of a lever structure, the stove of the present invention is more in line with the user's operating habits, which helps reduce the user's learning cost for operating the stove and is more convenient for the user to operate the stove. At the same time, because the lifting device 30 of the stove of the present invention converts the rotational motion of the hand-cranked mechanism 31 into the lifting motion of the lifting mechanism 32, the charcoal basin 20 can be prevented from suddenly moving upward or downward during the process of adjusting the height position of the charcoal basin 20, making the movement of the charcoal basin 20 smoother, which helps ensure the user's safe use of the stove of the present invention.

[0044] In addition, in the surrounding stove of the present invention, the reason why the lifting device 30 can convert the rotational motion of the hand-cranked mechanism 31 into the lifting motion of the lifting mechanism 32 is that the driving end 312 of the hand-cranked mechanism 31 is provided with an external thread, and the threaded hole 3241 of the driven part 324 is provided with an internal thread, and the external thread of the driving end 312 of the hand-cranked mechanism 31 and the internal thread of the driven part 324 are screwed together. Therefore, after the height of the charcoal basin 20 is adjusted to the right position, the gravity applied by the charcoal basin 20 to the support plate 322 will cause the driven part 324 to have a tendency to move in the horizontal direction. At this time, there is a large friction force between the internal thread of the driven part 324 and the external thread of the driving end 312 of the hand-cranked mechanism 31, so that the lifting device 30 is self-locking. In other words, the lifting device 30 of the stove of the present invention has a self-locking function, which means that the stove of the present invention does not require a special interlocking locking structure, thereby making the stove of the present invention simple in structure, easy to operate, and more reliable.

[0045] In the attached Figures 1 to 10 In the specific example of the stove of the present invention shown, the lifting mechanism 32 includes two support arms 323, one support arm 323 is connected to one side of the base 321 and one side of the support plate 322, and the other support arm 323 is connected to the other side of the base 321 and the other side of the support plate 322, and the opposite ends of the driven part 324 are rotatably mounted on the two support arms 323, so that the driven part 324 can drive the postures of the two support arms 323 to change synchronously when moving in the horizontal direction, thereby preventing the support plate 322 from tilting during the lifting process, and further preventing the charcoal basin 20 from tilting.

[0046] Reference Attachment Figures 6 to 10 The support arm 323 includes a first support rod 3233 and a second support rod 3234. The middle portions of the first support rod 3233 and the second support rod 3234 are hingedly connected, forming an "X" shape. The posture of the support arm 323 can be changed to adjust the height of the support plate 322. For example, the middle portions of the first support rod 3233 and the second support rod 3234 can be hingedly connected by a rivet 100. The first support rod 3233 and the second support rod 3234 can rotate about the hinged position of the first support rod 3233 and the second support rod 3234, so that the posture of the support arm 323 can be changed to adjust the height of the support plate 322.

[0047] Reference Attachment Figure 9With the hinged position of the first support rod 3233 and the second support rod 3234 as the boundary, the right side of the first support rod 3233 and the right side of the second support rod 3234 form the rotating side 3231 of the support arm 323, and the left side of the first support rod 3233 and the left side of the second support rod 3234 form the sliding side 3232 of the support arm 323. The bottom of the first support rod 3233 and the top of the second support rod 3234 are respectively slidably mounted on one end of the base 321 ( Figure 9 left end shown) and one end of the support plate 322 ( Figure 9 The left end shown in the figure), that is, the bottom and top of the support arm 323 located on the sliding side 3232 are slidably mounted on the base 321 and the supporting plate 322, respectively, and the top of the first support rod 3233 and the bottom of the second support rod 3234 are rotatably mounted on the other end of the supporting plate 322 ( Figure 9 the right end shown) and the other end of the base 321 ( Figure 9 The right end shown), that is, the bottom and top of the support arm 323 located on the rotating side 3231 are rotatably mounted on the base 321 and the supporting plate 322 respectively.

[0048] The end of the driven portion 324 is rotatably mounted on the first support rod 3233. For example, the end of the driven portion 324 and the first support rod 3233 may be rotatably mounted via the rivet 100.

[0049] When the user rotates the hand-cranked mechanism 31, the internal thread of the driven part 324 and the external thread of the driving end 312 of the hand-cranked mechanism 31 cooperate with each other to make the driven part 324 move in the horizontal direction. During the movement in the horizontal direction, the driven part 324 can push or pull the bottom of the first support rod 3233 and the top of the second support rod 3234 to slide relative to the base 321 and the support plate 322 respectively. At the same time, the bottom of the second support rod 3234 and the top of the first support rod 3233 rotate relative to the base 321 and the support plate 322 respectively to change the posture of the support arm 323 and realize the lifting and lowering of the support plate 322.

[0050] For example, in the attached Figures 1 to 10 In the specific example of the stove shown, when the user rotates the hand-crank mechanism 31 clockwise, the driven portion 324 moves horizontally toward the adjacent Figure 9The driven portion 324 moves to the right in the direction of the hand crank mechanism 31, and during the movement, the bottom of the first support rod 3233 and the top of the second support rod 3234 slide relative to the base 321 and the supporting plate 322 respectively. At the same time, the bottom of the second support rod 3234 and the top of the first support rod 3233 rotate relative to the base 321 and the supporting plate 322 respectively, so that the height of the supporting plate 322 is raised. When the user rotates the hand crank mechanism 31 counterclockwise, the driven portion 324 moves horizontally to the adjacent Figure 9 The driven part 324 moves in the left direction, and during the movement, the bottom of the first support rod 3233 and the top of the second support rod 3234 are pushed to slide relative to the base 321 and the supporting plate 322 respectively. At the same time, the bottom of the second support rod 3234 and the top of the first support rod 3233 are rotated relative to the base 321 and the supporting plate 322 respectively, so that the height of the supporting plate 322 is lowered.

[0051] Optionally, in other examples of the fire enclosure of the present invention, the bottom of the first support rod 3233 and the top of the second support rod 3234 are respectively rotatably mounted on one end of the base 321 and one end of the support plate 322, and the top of the first support rod 3233 and the bottom of the second support rod 3234 are respectively slidably mounted on the other end of the base 321 and the other end of the support plate 322, wherein the end of the driven part 324 is rotatably mounted on the second support rod 3234. When the user rotates the hand-cranked mechanism 31, the internal thread of the driven part 324 and the external thread of the driving end 312 of the hand-cranked mechanism 31 cooperate with each other to make the driven part 324 move in the horizontal direction. During the movement in the horizontal direction, the driven part 324 can push or pull the top of the first support rod 3233 and the bottom of the second support rod 3234 to slide relative to the support plate 322 and the base 321 respectively. At the same time, the bottom of the first support rod 3233 and the top of the second support rod 3234 rotate relative to the base 321 and the support plate 322 respectively to change the posture of the support arm 323 and realize the lifting and lowering of the support plate 322.

[0052] Reference Attachment Figures 8 to 10The base 321 has a base slide 3211, and the base slide 3211 extends along the length direction of the base 321. The supporting plate 322 has a supporting plate slide 3221, and the supporting plate slide 3221 extends along the length direction of the supporting plate 322. The support arm 323 includes a base guide element 3235 and a supporting plate guide element 3236. One end of the base guide element 3235 is set at the bottom of the first support rod 3233, and the other end of the base guide element 3235 extends to the base The base slide groove 3211 of 321 can slide along the base slide groove 3211, so that the bottom of the first support rod 3233 can be slidably installed on the base 321, and one end of the support plate guide element 3236 is set at the top of the second support rod 3234, and the other end of the support plate guide element 3236 extends to the support plate slide groove 3221 of the support plate 322 and can slide along the support plate slide groove 3221, so that the top of the second support rod 3234 can be slidably installed on the support plate 322.

[0053] It is worth mentioning that one end of the base guide element 3235 can be fixedly disposed on the bottom of the first support rod 3233, or can be rotatably disposed on the bottom of the first support rod 3233, and the cross-sectional dimension of the other end of the base guide element 3235 is smaller than the width dimension of the base slide groove 3211 of the base 321. In this way, the base guide element 3235 can slide along the base slide groove 3211 of the base 321 and can rotate relative to the base 321. For example, the base guide element 3235 can be a cylinder with a cross-sectional diameter dimension smaller than the width dimension of the base slide groove 3211 of the base 321.

[0054] Similarly, one end of the support plate guide element 3236 may be fixedly disposed on the top of the second support rod 3234, or may be rotatably disposed on the top of the second support rod 3234, and the cross-sectional dimension of the other end of the support plate guide element 3236 may be smaller than the width dimension of the support plate slide groove 3221 of the support plate 322. In this way, the support plate guide element 3236 may slide along the support plate slide groove 3221 of the support plate 322 and may rotate relative to the support plate 322. For example, the support plate guide element 3236 may be a cylinder having a cross-sectional dimension smaller than the width dimension of the support plate slide groove 3221 of the support plate 322.
