AI Technical Summary
Existing barbecue grills cannot effectively concentrate the heat from the charcoal bars in the later stages of combustion, resulting in heat loss, and they cannot adjust the heat distribution according to the size of the food being grilled.
The position of the carbon plate is adjusted by height and angle adjustment components, and the heat flow is controlled by shielding components to ensure that the heat is concentrated above the food being grilled. A worm gear mechanism is used to achieve concentrated accumulation and release of heat from the carbon strips.
It effectively reduces heat loss, improves thermal efficiency, and ensures concentrated heat release from the charcoal strips and uniform heating of the food during the later stages of combustion.

[0037] The product is used, the two sides of sliding rope 72 are driven along the sliding groove 71 to move forward, so as to drive the shielding plate 73 connected with the two sides of sliding rope 72, and the shielding plate 73 is sequentially arranged between the adjacent placing columns 6, so as to shield the heat flow, so that the heat emitted by the carbon strip on the carbon placing plate 2 only flows out between the part of the placing column where the roasted object is placed, and the setting of the connecting column 74 makes the shielding plate 73 can be arranged in the vertical direction at the rear side of the cabinet 1, and will not be jammed when passing through the turning place.
[0038] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , a pair of limiting rails 8 arranged in the height direction are arranged on the two sides of the front wall of the cabinet 1, the front ends of the two sliding ropes 72 are arranged outside the front side of the cabinet 1, a horizontal control plate 9 movably arranged in the height direction is arranged on the front wall of the cabinet 1, the left and right ends of the horizontal control plate 9 are fixedly connected with the front ends of the two sliding ropes 72 respectively, and a pair of limiting blocks 10 arranged in the corresponding limiting rails 8 are fixedly arranged at the rear end of the horizontal control plate 9.
[0039] The product is used, the horizontal control plate 9 is pulled downward, so that the rear limiting block 10 of the horizontal control plate 9 moves downward along the corresponding limiting rail 8, and drives the two sides of sliding rope 72 to move forward along the sliding groove 71, so as to drive the shielding plate 73 connected with the two sides of sliding rope 72, and the shielding plate 73 is sequentially arranged between the adjacent placing columns 6, so as to shield the heat flow, so that the heat emitted by the carbon strip on the carbon placing plate 2 only flows out between the part of the placing column where the roasted object is placed.
[0040] As shown in Figure 1 and Figure 3 , a heat shield 11 is fixedly arranged on the rotating handle 59.
[0041] The product is used, the user can hold the heat shield 11 when rotating the rotating handle 59, so as to prevent scalding.
[0042] As shown in Figure 2 and Figure 3 , the carbon placing plate 2 is provided with a rounded corner at the front and rear ends.
[0043] The product is used, the rounded corner prevents the carbon placing plate 2 from being jammed during forward and backward rotation.
[0044] As shown in Figure 1 and Figure 2 , a hinged door 12 is arranged on the left side of the cabinet 1.
[0045] The product is used, the carbon strip is taken out or placed on the carbon placing plate 2 by rotating the opening and closing door 12.
[0046] The working principle of the device is:
[0047] First step: open the opening and closing door 12, arrange the carbon strip placed on the carbon plate 2 after the completion of the pre-burning, then close the opening and closing door 12, and place the roasted material on the casing 1 above the respective material column 6 from front to back.
[0048] Second step: pull down the horizontal control plate 9, so that the rear limiting block 10 of the horizontal control plate 9 moves downward along the corresponding limiting rail 8, and drives the two sides of the sliding rope 72 to move forward along the sliding groove 71, thereby driving the shielding plate 73 connected with the two sides of the sliding rope 72, in turn, between the adjacent material columns 6, so as to shield the heat flow, so that the heat emitted by the carbon strip on the carbon plate 2 only flows out from the part of the material column where the roasted material is placed.
[0049] Third step: after a long time of carbon roasting, the burning material in each carbon strip on the carbon plate 2 is continuously reduced, resulting in that the heat emitted by a single carbon strip cannot meet the needs of carbon roasting, and the heat is further lost due to the influence of air through the gap on the upper part of the casing 1. At this time, the operator pulls out the pin 44, pushes down the horizontal pull plate 41, drives the two sides of the pull rope 32 to move, thereby pulling up the carbon plate 2, thereby reducing the distance between the carbon plate 2 and the material column 6, and pulling to the appropriate position, aligning the positioning hole 43 with the corresponding pin hole 42, and inserting the pin 44 into the locking horizontal pull plate 41, thereby fixing the position height of the carbon plate 2.
[0050] Fourth step: in order to concentrate the heat of the carbon strip below the unshielded part of the shielding plate 73, the operator holds the heat insulation sleeve 11 and rotates the rotating handle 59, drives the worm gear 53 to rotate circumferentially, thereby driving the worm gear 52 engaged with it to rotate, causing the threaded sleeve 54 screwed on the worm gear 52 to move backward along the length direction of the worm gear 52, causing the pusher 56 to move backward and continuously push the rear part of the carbon plate 2 upward, prompting the carbon strip above the carbon plate 2 to slide forward and accumulate in the front part of the carbon plate 2, thereby concentrating the carbon strip and releasing the heat.
[0051] The above is only a specific embodiment of the present application, and is not limited to the patent range of the present application. Any equivalent structural transformation or direct or indirect application in other related technical fields based on the content of the present application is also included in the patent protection range of the present application.
