[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0035] See Figures 1 to 9 As shown, an oven with a fan includes an oven body 1 and a grill 3. The oven body 1 has an oven cavity 11, and a charcoal rack 2 is arranged in the oven cavity 11. The grill 3 is arranged above the charcoal rack 2. The oven cavity 11 also has a fan 4 and an adjusting plate 5. The adjusting plate 5 is arranged between the fan 4 and the charcoal rack 2, and a gap is formed between the adjusting plate 5 and the side wall of the oven cavity 11. The adjusting plate 5 is provided with a control part 54 exposed on the outside of the oven head, which controls the movement of the adjusting plate 5 in the oven cavity 11. The gap between the adjusting plate 5 and the side wall of the oven cavity 11 can be changed. An air inlet 12 is provided at the lower part of the oven cavity 11. The fan 4 can drive outside air into the oven cavity 11 through the air inlet 12 and blow the air towards the charcoal rack 2 through the gap. The oven can drive the airflow in the oven cavity 11 through the blower 4, increasing the oxygen supply during the charcoal combustion process, which is beneficial to improve the combustion efficiency and temperature of the charcoal, thereby increasing the firepower of the oven. The regulating plate 5 can adjust the gap between the regulating plate 5 and the side wall of the oven cavity 11, which can change the airflow speed blown towards the charcoal rack 2, thereby regulating the oxygen supply during the charcoal combustion process, making it convenient for the user to adjust the firepower of the oven.

[0036] The adjusting plate 5 can be slidably disposed in the oven cavity 11. Although this structure is not shown in the accompanying drawings, those skilled in the art can implement this technical solution based on their own knowledge. In this utility model, the adjusting plate 5 is rotatably disposed in the oven cavity 11 via a horizontally extending rotating shaft. By controlling the rotation of the adjusting plate 5, the adjusting plate 5 can be vertically rotated around the rotating shaft, thereby adjusting the gap between the adjusting plate 5 and the side wall of the oven cavity 11. The rotatably disposed adjusting plate 5 is convenient for users to adjust and control, and facilitates users to adjust the size of the oven fire.

[0037] To ensure that the adjusting plate 5 can be fixed relative to the furnace body 1, a damping element can be provided on the adjusting plate 5, and a positioning protrusion 56 adapted to the furnace body 1 can also be provided on the adjusting plate 5. When a damping element is provided on the adjusting plate 5, the damping element cooperates with the furnace body 1 to increase the damping during the movement of the adjusting plate 5, thereby allowing the adjusting plate 5 to maintain different fixed states in the furnace cavity 11. The damping element can be a friction pad or a spring that drives the adjusting plate 5 and the furnace body 1 to be tightly connected. When the adjusting plate 5 is provided with a positioning protrusion 56, the furnace body 1 is provided with several positioning grooves 16 adapted to the positioning protrusion 56 to control the movement of the adjusting plate 5. The positioning protrusion 56 can cooperate with different positioning grooves 16 to keep the adjusting element and the furnace body 1 in different fixed states. Under the action of external force, the positioning protrusion 56 can disengage from the positioning groove 16 and switch between different positioning grooves 16. The damping element, positioning protrusion 56, and positioning groove 16 prevent the adjusting plate 5 from moving freely during use, which helps the adjusting plate 5 and the oven body 1 maintain different fixed states, making it convenient for users to use the oven. The accompanying drawings of this utility model only show the structure of the positioning protrusion 56 and positioning groove 16, and do not show the damping element; however, those skilled in the art can implement this technical solution based on their own knowledge.

[0038] A detachable ash collection box 6 is installed in the furnace cavity 11, and the ash collection box 6 has an ash collection chamber 61. The ash collection box 6 is located on one side of the blower 4, and a first guide surface 51 is provided on the upper side of the adjusting plate 5. By controlling the movement of the adjusting plate 5, the guide surface extending to the side above the ash collection box 6 can be tilted downwards, so that the ash generated in the charcoal rack 2 can be guided into the ash collection box 6 through the first guide surface 51. The first guide surface 51 not only facilitates the collection of ash, but also reduces the amount of ash falling onto the blower 4, preventing ash from affecting the movement of the blower 4, and also preventing the blower 4 from overheating due to ash, thus reducing oxidation damage to the blower 4.

[0039] Preferably, a second guide surface 52 is provided on the lower side of the adjusting plate 5, and the second guide surface 52 is inclined upward on the side away from the ash collection box 6; the airflow generated by the fan 4 can be blown towards the second guide surface 52 and guided by the second guide surface 52 through the gap between the adjusting plate 5 and the side wall of the furnace cavity 11. The setting of the second guide surface 52 not only facilitates the passage of air through the gap between the adjusting plate 5 and the side wall of the furnace cavity 11, but also reduces the force on the fan 4 during use and prevents the adjusting plate 5 from rotating accidentally during use. In this embodiment, the adjusting plate 5 has a hinge shaft 53 and a plate body, the first guide surface 51 and the second guide surface 52 are respectively provided on the upper and lower sides of the plate body, the control part 54 is provided at one end of the hinge shaft 53, and the side of the furnace body 1 is provided with a hinge hole 15, the positioning groove 16 is provided on the side of the hinge hole 15, the control part 54 is provided with a hinge part 55 adapted to the hinge hole 15, and the positioning protrusion 56 is provided on the side of the hinge part 55.

[0040] The furnace body 1 has an installation opening 13 on its side for the ash collection box 6 to pass through. The ash collection box 6 has a sealing plate 62 extending towards the side of the installation opening. The furnace body 1 also has a groove 14 on its side that matches the sealing plate 62, allowing the ash collection box 6 to be installed in the furnace cavity 11. The sealing plate 62 can then be inserted into the groove 14. The sealing plate 62 reduces the amount of air entering the furnace cavity 11 through the installation opening 13, minimizing or even preventing the ash from being blown up during this process, thus facilitating ash collection and reducing ash dispersion.

[0041] The sealing part is provided with a handle 63, which allows the user to control the ash collection box 6 to detach from the furnace chamber 11.

[0042] The fan 4 can be electrically driven, a common technique in the field. Those skilled in the art can implement this technical solution by combining existing technology and their own knowledge. Preferably, the fan 4 in this invention is mechanically driven. The fan 4 includes a housing 41, on which a driving component 44 and a fan blade 42 are rotatably mounted. The driving component 44 has a foot pedal 441 extending from the oven body 1. A gear set or linkage mechanism is provided between the driving component 44 and the fan blade 42, allowing the driving component 44 to drive the fan blade 42 to rotate. In this structure, the fan blade 42 can be controlled by stepping on the foot pedal 441, eliminating the need for electric drive and facilitating outdoor use of the oven. In this embodiment, the fan 4 includes two detachably connected housings 41, with the gear set or linkage mechanism located between the two housings 41.

[0043] When the driving member 44 drives the fan blade 42 to move through the linkage mechanism, the linkage mechanism is a crank-rocker mechanism, wherein the driving rod acts as a rocker, and the fan blade 42 is connected to the crank structure. In this utility model, the driving member 44 drives the fan blade 42 to rotate through a gear set. The rotation axis of the fan blade 42 extends vertically, so that the fan blade 42 can rotate horizontally. The rotation axis of the driving member 44 extends laterally, so that the foot pedal 441 can swing up and down. The driving member 44 is provided with a sector gear part 442, the fan blade 42 is provided with a first gear part 421, and a second gear part 43 is provided between the driving member 44 and the first gear part 421. The second gear part 43 is provided with a spur gear part 431 adapted to the sector gear part 442 and an end face gear part 432 adapted to the first gear part 421.

[0044] In this embodiment, an elastic element 45 is provided between the driving component 44 and the outer casing 41. The elastic element 45 can drive the driving component 44 to reset and cause the foot pedal 441 to swing upward. This structure facilitates the user to continuously step on the foot pedal 441, allowing the user to drive the fan blade 42 to rotate continuously via the foot pedal 441, thus facilitating the use of the oven.

[0045] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model.
