[0034] The fire control mechanism 2 includes a charcoal basin 201. The left and right sides of the charcoal basin 201 are slidably connected to the inside left and right sides of the barbecue frame 1, respectively, facilitating the removal, placement, cleaning, and maintenance of the charcoal basin 201. Multiple slots 202 are provided on the top front side of the charcoal basin 201 to provide positioning points for the partition plates 203. Multiple partition plates 203 are slidably connected to the front and rear sides of the interior of the charcoal basin 201. By inserting the partition plates 203 into the slots 202 at different positions, the charcoal basin 201 is divided into multiple independent spaces, limiting the accumulation of charcoal across areas to achieve temperature zoning, and coordinating with charcoal density control. Temperature control: The bottom left and right sides of the barbecue frame 1 are rotatably connected to dampers 204 to adjust the oxygen input and control the charcoal fire intensity. The bottom left and right sides of the inner side of the barbecue frame 1 are fixedly connected to guide the oxygen flow in a directional manner to improve combustion efficiency. The bottom of the charcoal basin 201 has multiple ventilation holes 206 to facilitate oxygen flow and contact with the charcoal fire to enhance the combustion effect. By controlling the opening and closing angle of the dampers 204, the guide plates 205 guide the oxygen input, which passes through the ventilation holes 206 and contacts the charcoal fire to control the charcoal fire temperature and achieve precise adjustment of the charcoal fire intensity.

[0035] The top of the barbecue frame 1 is equipped with an adjustment component 207. The adjustment component 207 is used to adjust the contact distance between the grill rack 2072 and the charcoal fire to adapt to the grilling needs of different ingredients. The adjustment component 207 includes two fixing plates 2071. The bottom of the two fixing plates 2071 is fixedly connected to the top left and right sides of the barbecue frame 1, respectively, to provide stable installation support for the grill rack 2072.

The front top of the two fixing strips 2081 is rotatably connected to the left and right ends of the rear side of the barbecue frame 1 to provide an installation carrier for the adjusting bolts 2082. The rear top of the two air dampers 204 are threaded with adjusting bolts 2082. The adjusting bolts 2082 pass through the fixing strips 2081 and are connected to the air dampers 204 to achieve a stable fixation of the opening and closing angle of the air dampers 204.

[0037] Specifically, when the fire control mechanism 2 is working, the partition plate 203 is first inserted into the slot 202 on the front side of the top of the charcoal basin 201, dividing the interior of the charcoal basin 201 into multiple independent spaces, restricting the accumulation of charcoal across areas to achieve temperature zoning. The temperature is adjusted by controlling the density of charcoal in each area. The left and right sides of the charcoal basin 201 are slidably connected to the inside of the grilling frame 1 for easy removal and cleaning. The air vents 204 on the bottom left and right sides of the grilling frame 1 are rotated to adjust the opening angle according to the grilling needs, and the guide plate 205 on the inner bottom guides oxygen. The oxygen flows through the ventilation holes 206 at the bottom of the charcoal basin 201 and comes into contact with the charcoal fire to control the temperature. In the adjustment component 207 at the top of the grill frame 1, hold the adjustment handles 2074 on the left and right sides of the grill rack 2072, slide them in the mounting grooves 2073 of the fixing plate 2071 and lock them into different slots 2075 to adjust the distance between the grill rack 2072 and the charcoal fire to suit the needs of the food. Finally, use the adjustment bolts 2082 of the fixing component 208 to pass through the fixing strip 2081 to fix the angle of the air vent 204 to ensure stable temperature control.

[0038] Reference Figure 1 , Figure 2 and Figure 5 The lifting mechanism 3 includes multiple connecting blocks 301. Adjacent connecting blocks 301 on the left and right sides are rotatably connected to outer rods 302, providing installation support for the lifting structure. The inner tops of the multiple outer rods 302 are rotatably connected to bevel gears 303, enabling power steering transmission. The inner left tops of the two left outer rods 302 and the inner right tops of the two right outer rods 302 are fixedly connected to helical gears 304. The multiple bevel gears 303 mesh with the multiple helical gears 304 respectively, enabling power transmission. The left end of the left helical gear 304 and the right end of the right helical gear 304 are rotatably connected to knobs 305, facilitating manual adjustment of the lifting mechanism. The bottoms of the multiple bevel gears 303 are rotatably connected to screws 306, converting rotational motion into linear motion. The outer bottoms of the multiple screws 306 are threaded with inner rods 307, enabling height adjustment via the screws 306.

[0039] The bottom of the inner rod 307 is provided with a support component 308 to enhance the stability of the grill placement. The support component 308 includes multiple ball joints 3081. The tops of the multiple ball joints 3081 are respectively fixedly connected to the bottoms of the multiple inner rods 307 to achieve multi-angle adaptation to the ground. The bottom outer sides of the multiple ball joints 3081 are rotatably connected to supports 3082 to increase the contact area with the ground. The tops of the left and right sides of the inner rod 302 are fixedly connected to the same limiting plate 6 to prevent the inner rod 307 from excessively raising and lowering. The top outer side of the inner rod 307 is slidably connected to the bottom inner side of the outer rod 302 to ensure smooth raising and lowering.

[0040] Specifically, when the lifting mechanism 3 is working, the knobs 305 on the left end of the left helical gear 304 and the right end of the right helical gear 304 are rotated, which drives the helical gear 304 inside the outer rod 302 to rotate. Multiple helical gears 304 mesh with the bevel gear 303 on the top inner side of the outer rod 302 to transmit power. The rotation of the bevel gear 303 drives the screw 306 at the bottom to rotate, converting the rotational motion into linear motion. The inner rod 307, which is threaded to the bottom outer side of the screw 306, slides on the bottom inner side of the outer rod 302 under the action of driving force to achieve height adjustment. The outer rod 302 obtains installation support through the rotational connection between the adjacent front and rear sides inside the connecting block 301. The limiting plates 6 on the top left and right sides inside prevent the inner rod 307 from being raised or lowered excessively. In the support component 308 at the bottom of the inner rod 307, the ball joint 3081 achieves multi-angle adaptation to the ground, and the support 3082, which is rotatably connected to the bottom outer side, increases the contact area with the ground to ensure the stability of the grill.

[0041] Reference Figure 1 , Figure 3 and Figure 4 The storage mechanism 4 includes two guide bars 401. The tops of the two guide bars 401 are fixedly connected to the bottom front and rear sides of the barbecue frame 1, providing guide tracks for the sliding of the placement plate 402. Two placement plates 402 are slidably connected between the adjacent guide bars 401 for classifying and storing ingredients to be grilled. Handles 403 are fixedly connected to the bottom of the two placement plates 402 on opposite sides for easy pulling out of the placement plates 402. The positioning mechanism 5 includes two support plates 501. The opposite sides of the two support plates 501 are fixedly connected to the left and right sides inside the barbecue frame 1, providing installation support for the positioning posts 502. Positioning posts 502 are fixedly connected to the top front and rear sides of the two support plates 501 to achieve positioning of the charcoal basin 201. Positioning holes 503 are opened at the four corners of the top of the charcoal basin 201, which cooperate with the positioning posts 502 to limit the displacement of the charcoal basin 201. The outer sides of the multiple positioning posts 502 are slidably connected to the inner sides of the multiple positioning holes 503 to ensure that the charcoal basin 201 is placed stably and prevents shaking.

[0042] Specifically, when the storage mechanism 4 and the positioning mechanism 5 are working, when storing food to be grilled, hold the handle 403 on the side of the bottom of the placement plate 402 that is far away from each other, so that the two placement plates 402 slide between the adjacent guide strips 401 on the front and rear sides of the bottom of the grilling frame 1. By pulling out the placement plate 402, the food can be classified and stored and easily retrieved. When positioning the charcoal basin 201, the support plates 501 on the left and right sides inside the grilling frame 1 provide installation support. Align the positioning holes 503 at the four corners of the top of the charcoal basin 201 with the positioning posts 502 on the front and rear sides of the top of the support plate 501, so that the outer sides of the multiple positioning posts 502 are slidably connected to the inner sides of the multiple positioning holes 503, limiting the displacement of the charcoal basin 201 to ensure stable placement and prevent shaking.

[0043] Working principle: When the fire control mechanism 2 is working, the partition plate 203 is first inserted into the slot 202 on the front side of the top of the charcoal basin 201, dividing the interior of the charcoal basin 201 into multiple independent spaces. By controlling the amount of charcoal in each space, the distribution of charcoal is limited, avoiding local overheating caused by cross-area accumulation, thus achieving temperature zoning. Then, according to the grilling requirements of the food, the air damper 204 is rotated to adjust the opening angle. The guide plate 205 on the bottom inner side of the grilling frame 1 guides the external oxygen to flow in a directional manner. The oxygen passes through the ventilation hole 206 at the bottom of the charcoal basin 201 and comes into contact with the charcoal. The temperature of the charcoal fire is controlled by adjusting the oxygen input. The angle of the damper 204 is fixed by the adjusting bolt 2082 of the fixing component 208 through the fixing strip 2081 to ensure stable temperature control. When adjusting the grill rack 2072, the adjusting handle 2074 is held and slid in the mounting groove 2073 of the fixing plate 2071. The adjusting handle 2074 is inserted into the slots 2075 at different positions to adjust the distance between the grill rack 2072 and the charcoal fire to adapt to the temperature requirements of different ingredients. The charcoal basin 201 can be easily removed, placed, and cleaned by sliding left and right.

[0044] Furthermore, when the lifting mechanism 3 is working, rotating the knob 305 drives the helical gear 304 inside the outer rod 302 to rotate. The helical gear 304 meshes with the bevel gear 303, causing the screw 306 to rotate. The screw 306 drives the threaded inner rod 307 to slide up and down inside the outer rod 302. The limiting plate 6 inside the outer rod 302 prevents the inner rod 307 from excessively lifting or lowering, ensuring safe and stable lifting. The ball joint 3081 at the bottom of the inner rod 307 cooperates with the support 3082 to adjust the support angle according to the flatness of the ground, increasing the contact area and lifting. To enhance stability, the connecting block 301 provides rotational support for the outer rod 302, ensuring smooth operation. When using the storage mechanism 4, the handle 403 is held to pull out the placement plate 402, which slides along the guide strip 401 to facilitate convenient retrieval and categorized storage of ingredients. When placing the charcoal basin 201, the positioning mechanism 5 aligns the positioning hole 503 of the charcoal basin 201 with the positioning post 502 of the support plate 501, allowing the positioning post 502 to slide into the positioning hole 503, preventing the charcoal basin 201 from shifting during use and ensuring a safe and stable grilling process.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
