Compared to existing technologies, this solution makes cleaning the grill more convenient and provides better cleaning results.

[0004] When in use, this invention cannot increase or decrease the heating range according to usage requirements, nor can it adjust the oxygen supply, thus making it impossible to regulate the heating temperature. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving charcoal grill with multi-stage temperature control to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-stage temperature-controlled energy-saving charcoal grill, comprising a grill body and a smoke extraction mechanism. The bottom of the grill body is mounted on the bottom of a support frame, and a holding plate is mounted on the upper end of the support frame at the bottom of the grill body. An air inlet is mounted on the front end of the grill body, and an air inlet regulating mechanism is mounted on the upper side of the grill body corresponding to the air inlet. A collection mechanism is slidably mounted below the rear end of the grill body. A grill is mounted in the middle of the interior of the grill body, and multiple charcoal boxes are placed side by side on the upper end of the grill body. A grilling grid is placed on the upper end of the grill body corresponding to the upper end of the charcoal boxes. The smoke extraction mechanism is mounted on one side of the upper end of the grill body, and a split mechanism is mounted on the upper side of the smoke extraction mechanism at the air inlet.

[0007] Preferably, the smoke extraction mechanism consists of an air duct, a fan, and a corrugated exhaust pipe. The air duct is installed on the upper side of one side of the furnace body, the fan is installed at one end of the air duct, and the bottom end of the corrugated exhaust pipe passes through the interior of the air duct and is installed at the upper end of the fan.

The collection trough is slidably installed at the bottom of the oven body, directly below the grill. During the grilling process, dust and residue generated by the charcoal fire in the charcoal box fall into the collection trough through the grill. The handles on both sides of the collection trough make it easy for users to pull out the collection trough and empty the dust and residue inside. The sliding design makes the collection trough easy to install and remove, and the cleaning process is simple and efficient. The collection trough can collect waste in a concentrated manner, preventing dust from falling into the oven body or on the ground, keeping the grill and the surrounding environment clean, and reducing the difficulty of cleaning. 4. The slide groove is installed on the outside of the air inlet, and the push-pull plate is slidably installed inside the slide groove. By operating the wrench on the outside of the push-pull plate, the push-pull plate can be moved to slide left and right along the slide groove to adjust the area of ​​the push-pull plate blocking the air inlet, thereby controlling the amount of air entering the oven body. The push-pull structure is easy to operate, and the wrench design makes it easy to apply force, allowing for quick and accurate adjustment of the air intake. By controlling the amount of air, the charcoal combustion intensity can be flexibly adjusted to meet the grilling temperature requirements of different ingredients, while avoiding excessive air that would cause the charcoal to consume too quickly, thus achieving energy-saving effects. In addition, the slide groove and the push-pull plate fit tightly, with good sealing performance and strong stability after adjustment. Attached Figure Description
