Description

Technical Field

[0001] This utility model relates to the field of round charcoal stove technology, and in particular to an adjustable damper for round charcoal stoves. Background Technology

[0002] The internal structure of a barbecue charcoal grill typically varies depending on the design, but the core components mainly include the outer shell, grill body, grill rack, charcoal mesh, damper blades, and ash tray. During use, the ash from burning charcoal accumulates at the bottom of the grill, which usually has an air inlet for ventilation and to allow the ash to fall downwards. However, most existing damper blades are flat, with their surface flush against the grill bottom. When adjusting the size of the air inlet by rotating the damper blades, the ash directly above the inlet falls directly downwards, while ash in other areas remains trapped and accumulates, clogging the air inlet and affecting the combustion intensity. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where ordinary damper blades are not easily able to dislodge the charcoal ash at the bottom of the furnace, thus proposing an adjustable damper for round charcoal furnaces.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The design includes an adjustable damper for a round charcoal stove, comprising a top cover that covers the stove body. A baking net is placed on the upper part of the stove body, and a charcoal net is placed inside the stove body. Ventilation holes are provided on the lower surface of the stove body. A rotating shaft is provided inside the lower part of the stove body, and damper blades are fixedly installed on the upper end of the rotating shaft. A damper ring is also fixedly connected to the lower surface of the stove body by bolts. A strip groove is provided on one side of the damper ring. A pull rod is fixedly connected to the lower end of the rotating shaft. The end of the pull rod passes through the strip groove and extends to the outside of the stove body. An ash pan is snapped into the bottom of the damper ring.

[0006] Preferably, the top cover has an exhaust hole on its surface, and a baffle is rotatably provided inside the top cover. A lever is fixedly installed on the upper surface of the baffle, and the end of the lever extends through to above the exhaust hole.

[0007] Preferably, the damper blade has an upward bulge in the middle, resembling a rib.

[0008] Preferably, the number of fan blades of the damper corresponds to the number of ventilation holes.

[0009] Preferably, the plane in which the strip groove is located is horizontal, and the central axis of the rotating shaft is vertical.

[0010] Preferably, an ash-straining frame is installed inside the ash pan, and a dome plate is fixedly installed in the middle of the ash-straining frame.

[0011] Preferably, the ash-discharging frame is perforated.

[0012] Preferably, the dome plate has an upward bulge in the middle, forming an arc shape.

[0013] The adjustable damper for a round charcoal stove proposed in this utility model has the following advantages: During operation, food can be placed on the grilling net and charcoal blocks can be placed on the charcoal net. Both the grilling net and the charcoal net are easy to remove for cleaning or replacement. By moving the lever, the rotating shaft can be driven to rotate, which in turn drives the damper blades to rotate. The rotation of the damper blades can also adjust the size of the ventilation holes, thereby controlling the fire. During the rotation of the damper blades, the ash at the bottom of the stove can also be stirred, making it easier to sweep the ash into the ash tray. Ash that falls on the blades can also be brushed off, improving the air intake effect inside the stove. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figure 1-6 The round charcoal stove features an adjustable air damper and includes a top cover 1, which sits atop the stove body 4. A grilling rack 2 is mounted on the upper part of the stove body 4, on which food can be placed. Inside the stove body 4, a charcoal mesh 3 is installed, on which charcoal blocks can be placed. Once the charcoal blocks are lit, the food is cooked. The top cover 1 can be removed from the stove body 4 for easy removal of the food. Both the grilling rack 2 and the charcoal mesh 3 are easily removable for cleaning or replacement.

[0025] An ash tray 13 is snapped onto the bottom of the damper ring 12. The ash tray 13 is used to collect furnace ash, and the ash can be poured out by removing the ash tray 13. Ventilation holes 7 are opened on the lower surface of the furnace body 4. The ventilation holes 7 serve to introduce air and provide ventilation. A rotating shaft 9 is rotatably installed inside the lower end of the furnace body 4. A damper blade 8 is fixedly installed on the upper end of the rotating shaft 9. The rotation of the rotating shaft 9 can drive the damper blade 8 to rotate. The number of damper blades 8 corresponds to the number of ventilation holes 7. The edges of the damper blades 8 are arc-shaped, which makes it easy to fit tightly against the bottom of the furnace body. During the rotation of the damper blades 8, they can stir the furnace ash at the bottom of the furnace, making it easier for the furnace ash to fall into the ash tray 13 from the ventilation holes 7. At the same time, the middle of the damper blades 8 is raised upward in a rib shape, which increases the strength and forms an angle, making it easier to shovel the furnace ash.

[0026] A damper ring 12 is also fixedly connected to the lower surface of the furnace body 4 by bolts. A strip groove 11 is opened on one side of the damper ring 12. The plane in which the strip groove 11 is located is horizontal. The central axis of the rotating shaft 9 is vertical. A pull rod 10 is fixedly connected to the lower end of the rotating shaft 9. The end of the pull rod 10 passes through the strip groove 11 and extends to the outside of the furnace body 4. When the pull rod 10 is moved, the rotating shaft 9 can be rotated. The rotation of the rotating shaft 9 can drive the damper blade 8 to rotate. During the rotation of the damper blade 8, the size of the ventilation hole 7 can be adjusted, so that the firepower can be controlled by controlling the size of the air inlet.

[0027] The top cover 1 has an exhaust hole 16 on its surface, and a baffle 17 is rotatably mounted inside the top cover 1. A lever 18 is fixedly installed on the upper surface of the baffle 17, and the end of the lever 18 extends above the exhaust hole 16. Moving the lever 18 can drive the baffle 17 to rotate, and the diameter of the exhaust hole 16 can be adjusted when the baffle 17 rotates. The exhaust effect is optimal when the groove on the surface of the baffle 17 is completely aligned with the exhaust hole 16; when the baffle 17 completely covers the exhaust hole 16, the top cover 1 stops venting, and the user can adjust the exhaust volume as needed.

[0028] Working principle: During operation, the adjustable damper of this round charcoal stove allows food to be placed on the grilling mesh 2 and charcoal blocks to be placed on the charcoal mesh 3. When the food is grilled by the charcoal blocks, external air enters through the through holes on the side wall of the damper ring 12, flows upward through the ventilation holes 7, and is finally discharged through the exhaust holes 16. By moving the lever 10, the rotating shaft 9 can be rotated, which in turn drives the damper blades 8 to rotate. The rotation of the damper blades 8 can adjust the size of the ventilation holes 7, thereby controlling the heat. During the burning of the charcoal blocks, ash will fall off. During the rotation of the damper blades 8, the raised part in the middle can also push the ash at the bottom of the stove, allowing the ash to fall into the ash tray 13 through the ventilation holes 7. The ash tray 13 is easy to disassemble, making it convenient to empty the ash from the ash tray 13.

[0029] Example 2: In Example 1, after the ash accumulates in the ash pan 13, when external air enters through the holes in the side wall of the damper ring 12, the air easily blows a large amount of ash upwards during the flow process, causing soot to fill the interior of the furnace body 4. Therefore, this example is proposed. (Refer to...) Figure 7-8 As another preferred embodiment of this utility model, based on embodiment 1, an ash-straining frame 14 is provided inside the ash pan 13. The ash-straining frame 14 is perforated and hollow. A dome plate 15 is fixedly installed in the middle of the ash-straining frame 14. The middle of the dome plate 15 is raised upward in an arc shape. When the ash from the bottom of the furnace falls into the ash pan 13, the ash will slide down along the dome plate 15. The sliding ash settles to the bottom of the ash pan 13 through the ash-straining frame 14. A large amount of ash is deposited below the ash-straining frame 14, and a small amount of oil-soaked ash remains above the dome plate 15 and the ash-straining frame 14. When the air flows, it is not easy to carry away the ash.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
