[0010] Preferably, the support block is provided with a blocking ring, the blocking ring is fixedly connected to the support block, and the blocking ring is fixedly connected to the chimney.

[0011] Beneficial effects:

[0012] This utility model provides a three-in-one barbecue grill with the following beneficial effects. Through its structural design, the device first preheats the gas stove on the left, while simultaneously adding an appropriate amount of charcoal to the central charcoal grill and igniting it. The heat from inside the charcoal grill is transferred through the ventilation opening to the pellet oven, slowly igniting and burning the placed wood pellets. This produces aroma in the pellet oven without causing excessive burning. The ignition system on the gas stove can control and adjust the fire intensity to maintain the required heat level. The degree of obstruction of the chimney opening by the adjustment plate above the chimney adjusts the temperature and smoke concentration inside the charcoal grill. During adjustment, rotating the gear on the support block moves the rack, which in turn moves the adjustment plate along the position of the limiting block. This sliding of the adjustment plate changes the size of the chimney opening, allowing the combustion efficiency and smoke concentration inside the charcoal grill to reach the user's desired level. When the ideal temperature is reached, food can be placed on the grill racks of each grill. The gas stove on the left is constantly rapidly... The first section is for grilling foods such as seafood and vegetables; the second section is for grilling traditional foods that require more smokiness, such as meats; and the third section is for slow-roasting or smoking foods at a relatively low temperature, allowing the food to slowly absorb the unique aroma released by the wood pellets. Compared to existing technologies, this invention combines three heat sources, utilizing the convenience of gas, preserving the traditional flavor of charcoal, and adding the unique aroma of wood pellets. The pellet oven is used to hold the wood pellets, allowing them to interact with the heat generated by the charcoal without directly contacting the flames, ensuring they continuously release smoke and aroma. Furthermore, unlike existing chimneys where only a thin sheet covers the chimney opening and connects to it through a single rotating point, this invention uses multiple limiting blocks connected to an adjusting plate. This reduces wear caused by single-point stress and prevents damage to the adjusting plate's connection points due to prolonged use or high temperatures, thus extending its lifespan. The use of gears and racks allows users to more accurately adjust the ventilation, enhancing the cooking experience. Attached Figure Description
