One having ordinary skill in the relevant art, however, will readily recognize that the invention can be practiced without one or more of the specific details or with other methods.

The present invention is not limited by the illustrated ordering of acts or events, as some acts may occur in different orders and/or concurrently with other acts or events. Furthermore, not all illustrated acts or events are required to implement a methodology in accordance with the present invention.

[0015] The word exemplary is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as exemplary is not necessarily to be construed as preferred or advantageous over other aspects or designs. Rather, use of the word exemplary is intended to present concepts in a concrete fashion. As used in this application, the term or is intended to mean an inclusive or rather than an exclusive or. That is, unless specified otherwise, or clear from context, X employs A or B is intended to mean any of the natural inclusive permutations. That is if, X employs A; X employs B; or X employs both A and B, then X employs A or B is satisfied under any of the foregoing instances.

[0016] Referring now to FIGS. 1-5, where like numerals indicate like features, an exemplary electrically powered liquid aeration device 10 may be configured for removable insertion into the mouth of a typical bottle, such as for example a wine or liquor bottle 13. Located at the top distal end of the aeration device 10 may be a spout 12 that is configured to transfer the liquid from the bottle 13 to a glass or other container. At the distal ends of the spout 12 may be an exit 12a and entrance 12b which may be configured to allow the aerated liquid to easily transfer out of the spout 12 into a glass or other container. Affixed to the bottom distal end of the spout entrance 12b may be a cap 14 which is configured to cover the opening of the bottle 13 and allow the transfer of the liquid from the bottle 13 into the spout 12. A plurality of passageways 26 may be disposed in a top surface of the cap 14 to allow for the liquid to transfer from the bottle 13 in a controlled manner. An impeller 24 may be affixed to the shaft of an electric motor 15 such that it rotates at a high speed. The impeller 24 may be configured to rotate such that it strikes the liquid as it exits the bottle 13 through the passageways 26. The impeller 24 is configured to spray or diffuse the liquid against the interior Avails of the spout 12 as it rotates and thereby significantly increases the amount of liquid that is exposed to air. A person of skill in the art will quickly realize that myriad design configurations can be used for the shape and action of the impeller 24, all such variations are contemplated by this invention and the configuration of the impeller 24 as shown by the figures should not limit the scope of the invention.

[0017] A central housing 16 may be affixed to the cap 14 and is sized to fit down into the mouth of the bottle 13 and reside in the mouth of the bottle 13 while being used. The central housing 16 may be comprised of an upper distal portion 15a where the electric motor 15 is coaxially disposed and retained; a sealing portion 19 that is configured to sealingly engage against the inside wall of the bottle 13 to prevent liquid from leaking from the bottle 13 while the liquid is being poured out of the bottle; an inlet portion 21 which allows the liquid to be directed from the bottle around the electric motor 15 and to the passageways 26 as shown by arrows 23 (FIG. 4); and, a co-axial internal cavity portion 17 where a battery 32, a receive recharging circuit 28 and a tilt switch 30 may be retained in a liquid tight cavity. Disposed at the lower distal end of the central housing 16 may be a removable cap 39. The tilt switch 30 is configured to allow voltage to flow from the battery 32 to the motor 15 only when the aeration device 10 is tipped to a predetermined angle which occurs as the liquid is being poured from a bottle. This therefore powers the spinning of the impeller 24 only when liquid is being transferred out of the bottle 13 and eliminates the need for a manual switch. Alternatively, the recharging circuitry just described could be replaced by a simple battery that may be replaced by the user when the battery runs out.

[0018] As can be seen from the description, the aeration device 10 has been configured so that impeller 24, motor 15, battery 32 and tilt switch 30 is all arranged and packaged in a co-axial fashion so that it may be inserted completely into the mouth of the bottle 13 which provides for an aesthetically pleasing and efficient means for aeration of a liquid as the liquid is poured from a bottle. This unique co-axial arrangement also allows for a low cost yet extremely reliable aeration device 10.

[0019] A charging base 18 may be provided that may be configured to removably retain the aeration device 10. The charging base 18 may comprise a receptacle portion 20 that is configured to removably engage the lower distal end of the central housing 16. A bottom cover 22 may be affixed to the bottom of the charging base 18. Disposed internally to the base 18 may be a transmit charging circuit 36 that is configured to wirelessly transmit an electrical charge to the receive recharging circuit 28 when the aeration device 10 is inserted into the charging base 18. A standard electrical connector 38 may be disposed on the charging base 18 and is in electrical communication with the transmit charging circuit 36. The charging base 18 is therefore configured to wirelessly charge the battery 32 that is disposed in the aeration device 10. As mentioned previously, it would be possible to eliminate the recharging circuitry and instead use a non-rechargable battery that can be replaced by the user.

[0020] Referring now to FIG. 5, which shows the electrical schematic of the aeration device 10 and the charging base 18, the function of the recharging feature of the device will be described in more detail. In an exemplary embodiment, battery 32 is in electrical communication with the motor 15 via a tilt switch 30 m any well-known manner. In an exemplary embodiment of the invention, the battery 32 is a rechargeable lithium polymer or lithium ion battery with a DC voltage between 3-12 VDC. The motor 15 may be a coreless DC motor capable of 1,000-30,000 rpm rotational speed. The tilt switch 30 in an exemplary embodiment of the invention may be a ball type tilt switch that is configured to close the circuit when the device 10 is tipped about 45 degrees from the vertical axis so that it provides power to the motor 15 and starts the rotation of the impeller 24 as the bottle 13 is being tipped to pour the liquid.

[0021] The receive recharging circuit 28 is in electrical communication with the battery 32 and is configured to replenish the electrical charge in the battery 32. A receive coil 28a is connected to the recharging circuit 28 and allows for the inductive reception of energy from the transmit charging circuit 36. The receive coil 28a is disposed near the cap 34 of the aeration device 10. A transmit coil 36a is in electrical communication with the transmit charging circuit 36 and is disposed in the charging base 18 so that it may wirelessly transmit electrical energy to the receive coil 28a when the aeration 10 is inserted into the charging base 18. While an exemplary embodiment of the invention as described so far has been focused on a wireless/inductive method for recharging the battery, it would be possible to have a physical connection between the charging base 18 and the aeration device 10, this approach is fully contemplated by this invention. Alternatively, the battery could be a standard non-rechargable battery that is replaced when it no longer provides the necessary power.
