DESCRIPTION OF PREFERRED EMBODIMENTS

Referring now to FIG. 1-6, the present invention features a coal-preparing device 100 for burning charcoal briquettes 101. The coal-preparing device 100 can help facilitate the burning of the charcoal briquettes 101, which causes the charcoal briquettes 101 to become coals. The coal-preparing device 100 of the present invention is portable.

Referring now to FIG. 1 and FIG. 2, the coal-preparing device 100 comprises a base 110. The base 110 has a top surface and an inner cavity. The base 110 may be constructed in a variety of shapes. For example, in some embodiments, the base 110 is generally flat (and elongated). In some embodiments, the base 110 has a L-shaped configuration. The present invention is not limited to the aforementioned examples.

Disposed on the top surface of the base 110, for example at or near a first side, is a fan component 120. Fan components are well known to one of ordinary skill in the art. For example, the fan component comprises a plurality of blades attached to an axle and a motor for driving the rotation of the axle. The fan component 120 of the present invention draws air into the inner cavity of the base 110 from outside the base 110. The fan component 120 is operatively connected to a control switch 128, which can move between a first position to turn the fan component 120 on and a second position to turn the fan component 120 off. The fan component 120 is operatively connected to power source (e.g., a battery). In some embodiments, the fan component 120 is covered via a grate 129 disposed in the top surface of the base 110 (see FIG. 2).

Disposed on the base 110 is a canister 130. The canister 130 is attachable to a first position on the base 110, for example on the top surface of the base 110, at or near a second side. The canister 130 has a bottom surface, an open top, and an inner cavity. In some embodiments, a handle 136 is disposed on the canister 130 (e.g., on the outside surface), which provides a user an easy means to lift and carry the canister 130. A plurality of air holes 138 is disposed in the bottom surface of the canister 130 (see FIG. 2).

The canister 130 may be removably or fixedly attached to the base 110. As shown in FIG. 1, the canister 130 is removably attached to the base 110 and the canister 130 can be temporarily secured to the base 110 via a securing means. In some embodiments, the securing means includes a pin and hook system. For example, locking pins 142 may be disposed on the canister 130 (e.g., near the bottom surface of the canister 130) that are configured to engage locking hooks 144 disposed on the base 110. The securing means is not limited to the aforementioned examples, for example the securing means may include a snap mechanism, a clamp mechanism, an adhesive mechanism, a hinge mechanism, the like, or a combination thereof.

In some embodiments, one or more pores 150 are disposed in the base 110 (e.g., in the top surface of the base 110). For example, as shown in FIG. 1, a plurality of pores 150 is disposed in the base 110, the pores 150 being located where the canister 130 is removably attached to the base 110 (e.g., in the first position). Air blown into the inner cavity of the base 110 via the fan component 120 can be blown out of the base 110 via the pores 150. If the base 110 is atop the pores 150, air from the pores 150 is directed into the inner cavity of the canister 130 via the air holes 138 in the canister 130. In some embodiments, an optional platform 160 with pores 150 is disposed on the top surface of the base 110 (e.g., the first position on the base 110). The platform 160 can engage the bottom surface of the canister 130. In some embodiments, a recess is disposed in the bottom surface of the canister 130, which is adapted to receive the platform 160. The platform 160 and recess together may help provide a strong connection between the base 110 and the canister 130, for example they may help provide an air-tight seal between the base 110 and canister 130.

Referring now to FIG. 3 and FIG. 4, charcoal briquettes 101 can be inserted into the inner cavity of the canister 130. Air drawn into the inner cavity of the base 110 via the fan component 120 is directed through the pores 150 in the base 110 and further through into the inner cavity of the canister 130 via the air holes 138 in the canister 130. When the charcoal briquettes 101 are lit (e.g., and soaked with a lighter fluid or cooking oil), the air from the base 110 can help the charcoal briquettes 101 burn more effectively. When the charcoal briquettes 101 have burned long enough to become coals, they can be removed (e.g., the canister 130 can be removed from the base 110) and placed into a grill 105.

In some embodiments, the bottom surface of the canister 130 is generally flat. As shown in FIG. 3, in some embodiments, the bottom surface of the canister 130 is not generally flat but is slanted or curved (e.g., curved inwardly). The curved or slanted bottom surface of the canister 130 may help increase efficiency of burning of the briquettes 101, for example by increasing the surface area of briquettes 110 that can be contacted by the flowing air.

A battery compartment 220 for holding a battery may be disposed in the base 110, for example in the inner cavity of the base 110 (e.g., near the fan component 120). In some embodiments, the battery compartment 220 comprises an access door 224, which can move between an open and closed position respectively allowing and preventing access to the battery compartment 220 (e.g., for changing batteries). In some embodiments, the battery compartment 220 is insulated with insulation material 228 (e.g., for safety of the battery).

Referring now to FIG. 5 and FIG. 6, the base 110 may be constructed in an L-shape, the L-shape having a horizontal portion and a vertical portion. The top surface of the base 110 may refer to the top surface of the horizontal portion. In some embodiments, the top surface of the base 110 may also refer to the first side surface or the second side surface of the vertical portion. The fan component 120 may be disposed in the vertical portion. The fan component 120 draws air into the inner cavity of the base 110 via the first side surface of the vertical portion.
