DETAILED DESCRIPTION

[0029] As shown in FIGS. 1-6, the device features a lower chamber 100, a middle chamber 102, an upper chamber 104, a head 106, and an extension 108. The lower chamber is attached to the middle chamber, the middle chamber is attached to the upper chamber, the upper chamber is attached to the head, and the head is attached to the extension. Attachment means may include molding the components as one piece, threadable engagement, click-in-place mechanisms, magnets, or snap-fit extensions. The chambers may be made of any feasible material that resists deformation, heat, and is not electrically conductive. Preferably, surfaces will be smooth for easy cleaning.

[0030] The lower chamber features a control panel 200, a set of ridges 202, a bulge 204, and a battery cavity 206. The control panel may comprise one or more buttons or switches. In one embodiment, a button is positioned on the bulge and the bulge is disposed on a side of the lower chamber opposite the finger ridges, thereby allowing for control of the device using the thumb. The bulge is designed to be held substantially flush with the palm for more ergonomic use of the device. The bulge and finger ridges may be made of a hard plastic or like material, or be formed from a compressible or elastic material for increased comfort. The average diameter of the lower chamber may be between 1.5 and 2 inches, but the bulge and finger ridges may widen the diameter to the upper range of 2 inches or exceed it. The length of the lower chamber may be between 3.5 and 5 inches.

[0031] The middle chamber features a series of openings or vents 300. The vents may be arranged in columns, with the columns arranged side-by-side and wrapping around the wall of the middle chamber, which may be cylindrically-shaped. The middle chamber may have an average diameter greater than the average diameter of the lower chamber, preferably between 2 and 3 inches, thereby providing a greater internal space of the fan 304 diameter. The middle chamber may measure in length 0.5 to 1.5 inches.

[0032] The upper chamber may be concentrically continuous with the middle chamber. The upper chamber may measure between 2 and 3 inches in diameter, and in a preferred version less than 0.25 inches larger or smaller than the middle chamber, thereby taking full advantage of the diameter and pulling surface of the fan. As shown in FIG. 7, the upper chamber and the head feature an engagement mechanism including a bead 404, a bead track 302, and an impediment 304.

[0033] As shown in FIG. 8, the head features a cylindrical portion 400 and a tapered portion 402. In one embodiment, the cylindrical portion features the bead on an inner surface, this bead disposed substantially inward so that the head may be fitted to the upper chamber which features a bead track on an outer surface, the bead aligning with and traveling down the bead track in a direction toward the lower chamber. Accordingly, the upper chamber diameter is slightly less than the cylindrical portion of the head. The bead track may feature a circumferential portion that is orthogonal to the main portion of the track and wrapping partially around the upper chamber, thereby permitting the head to be rotated with respect to the upper chamber. Once the bead passes onto the circumferential portion, the head and upper chamber can no longer be separated along an axis featuring the upper chamber and the lower chamber, but instead must be rotated in a reverse direction so that the bead may once again align with and navigate the main portion of the bead track. To decrease the ease with which the upper chamber and the head rotate with respect to one another, an impediment, such a small extension of the base material, may extend from the track between the circumferential portion and main portion of the track. Additional force is required by the user to overcome the resistance posed by the impediment to rotation. Preferably, the cylindrical portion of the head comprises the same diameter as the middle chamber, so that when the head covers the upper chamber, the outer walls of the head and the middle chamber are flush, thereby providing an easier cleaning surface.

[0034] The extension features a stem 500, a seal 502, an opening 504, and a set of bristles 506 which are disposed on the stem and extend outward radially from it. The stem is a hollow structure in fluid communication with the opening 504 and the head via a second opening (not shown) that traverses the seal. The diameter of the stem may measure between 0.25 to 1 inch, though in another embodiment, them stem is approximately of the same diameter as the head.

[0035] As shown in FIG. 9-10, the lower chamber features a housing for a motor 208, the motor electrically connected to a power source 210 and a circuit board 212. The middle chamber features a fan 304, and a channel 306. The upper chamber features a frame 404, a filter 406, a divider 408, a top opening 410 and a bottom opening 412.

[0036] As shown in FIG. 11-12, the stem can be bent, curved, angular, or pivotable.
