[0026] A rear plate 8 is provided below the collecting top 3. A hinge 9 is provided on the outer wall of the rear plate 8. The rear plate 8 is connected to the collecting top 3 through the hinge 9. Rotating blocks 5 are provided on both sides of the rear plate 8, and a side plate 4 is provided at the other end of the rotating block 5.
[0027] The technical solution provided in this embodiment is as follows: In use, firstly, insert one end of the first support rod 17 and the second support rod 18 into the fixing block 19, then place the contact block 22 on the ground. Next, insert the limiting rod 21 into the blind hole opened on the surface of the first support rod 17 and the second support rod 18 to further fix the first support rod 17 and the second support rod 18 in case they move during use. Next, open the front plate 2 and insert the lifting plate 12 above the clamping plate 13. Then, place the charcoal above the lifting plate 12. After proper ignition, close the front plate 2 and lock the front plate 2 to the barbecue grill 1 using the locking block 23. Place the placement plate 14 above the placement edge 15, and then install the collection top 3. During installation, first unfold the rear plate 8 and the side plate 4, and align the positioning block 6 of the side plate 4 with the positioning block 6 on the outer wall of the barbecue oven 1. Then insert the pin 7 into the inner wall of the positioning block 6 to fix the collection top 3. After that, it can be used. If used indoors, it needs to be used in front of the range hood or window to enhance ventilation and prevent the combustion smoke from accumulating indoors. When in use, the collection top 3 collects the smoke and discharges it through the chimney 10. The chimney 10 is designed to extract the smoke faster by utilizing the chimney effect, and the anti-backflow top 11 prevents the smoke from flowing back in.
[0028] Furthermore, a chimney 10 is installed above the collection top 3, and an anti-spraying top 11 is installed at the output end of the chimney 10.
[0029] Specifically, the chimney 10 and the anti-backflow top 11 are designed so that the chimney 10 can quickly discharge the flue gas and prevent the flue gas from spreading everywhere, and the anti-backflow top 11 can prevent the flue gas from flowing back.
[0030] Furthermore, both the inner walls of the barbecue grill 1 and the front panel 2 are provided with a retaining plate 13, the upper surface of the retaining plate 13 is provided with a lifting plate 12, the inner walls of the barbecue grill 1 and the front panel 2 are provided with a placement edge 15, and a placement plate 14 is provided above the placement edge 15.
[0031] Specifically, by setting up the raised plate 12, the carbon can be prevented from directly contacting the bottom plate, allowing it to come into more full contact with air during combustion, thus increasing the combustion efficiency of the carbon.
[0032] Furthermore, both the outer walls of the barbecue grill 1 and the front panel 2 are provided with locking blocks 23, which are connected by screws. Both the side panel 4 and the outer walls of the barbecue grill 1 are provided with positioning blocks 6, and the inner walls of the positioning blocks 6 are fitted with pins 7.
[0033] Specifically, the locking block 23 can fix the front plate 2, making the fixation of the front plate 2 more stable, and the positioning block 6 can fix the collecting top 3.
[0034] Furthermore, a fixing block 19 is provided at the bottom of the barbecue grill 1. A first support rod 17 and a second support rod 18 are inserted into the inner wall of the fixing block 19. The second support rod 18 passes through the first support rod 17. The second support rod 18 and the first support rod 17 are arranged to cross each other. A plug rod 20 is inserted at the intersection of the second support rod 18 and the first support rod 17.
[0035] Specifically, by setting up the first support rod 17 and the second support rod 18, the barbecue grill 1 can be lifted off the ground, and it can occupy less space when not in use or when stored.
[0036] Furthermore, blind holes are provided on the inner walls of the first support rod 17 and the second support rod 18. A limiting rod 21 is inserted into the inner wall of the first support rod 17, and the other end of the limiting rod 21 is inserted into the inner wall of the second support rod 18. A contact block 22 is provided at the end of both the first support rod 17 and the second support rod 18.
[0037] Specifically, by setting the limiting rod 21, the first support rod 17 and the second support rod 18 can be further fixed, making it more stable during use.
[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
