Commonly-assigned U.S. Pat. No. 5,388,594, which is incorporated herein by reference in its entirety, discloses an electrical smoking;system that includes an electrically heated cigarette smoking device. An electrical smoking system, such as that disclosed in the '594 patent, can provide sensations of smoking that closely resemble those experienced during smoking of a conventional cigarette, but without certain disadvantages. Other exemplary electrically heated cigarette smoking systems are disclosed in commonly-assigned U.S. Pat. Nos. 5,269,327; 5,878,752; 5,954,979; 5,967,148; and 6,349,728, each of which is incorporated herein by reference in its entirety.
A stand for an electrically heated cigarette smoking device is provided. A preferred embodiment of the stand is adapted to support an electrically heated cigarette smoking device including a rechargeable power supply, and a charger for the electrically heated cigarette smoking device.
In another preferred embodiment, the stand provides electrical connection to a power source that provides power to the electrically heated smoking device. Charging electronics in the electrically heated cigarette smoking device, or in the stand, control charging of the rechargeable power supply.
In another preferred embodiment, the stand provides charging capabilities for an electrically heated cigarette smoking device.
The stand can include fasteners to allow the stand to be removably or permanently fastened to a surface.
In a preferred embodiment, the stand is configured to fit in a cup holder of a vehicle. In such embodiment, the power source for the electrically heated cigarette smoking device can be a power source in the vehicle.
In a preferred embodiment, the stand includes an opening configured to receive an electrically heated cigarette smoking device. Accordingly, the device can be stored on the stand when not held by a user.
In a preferred embodiment, the stand operates on direct current (DC). Accordingly, a rechargeable DC power supply of the electrically heated cigarette smoking device can be recharged by electrically connecting the stand to a DC power source.
In another preferred embodiment, the stand includes inductive charging electronics operable to convert DC supplied to the stand by a DC power source to alternating current (AC), and convert the AC back to DC, to recharge the power supply of the electrically heated cigarette smoking device.
A stand useful for storing an electrically heated cigarette smoking device is provided. The stand can be used in various vehicles including automobiles, trucks, buses, and the like.
The electrically heated cigarette is smoked in a similar manner as a traditional cigarette. However, the heater heats the cigarette without lighting or continuous smoldering of the cigarette. These and other characteristics of electrically heated cigarette smoking systems make them attractive for use in confined spaces.
The electrically heated cigarette smoking device 10 can be used with various chargers, such as those illustrated in
The charger 20 has a bottom support surface 26, which is shaped to rest on a support surface. The charger 20 also includes surfaces 28 and 29, which are shaped to support the electrically heated cigarette smoking device 10.
The electrically heated cigarette smoking device 10 can include an internal power supply, and charging electronics operable to control charging of the power supply by an external power source when the electrically heated cigarette smoking device 10 is supported on the charger 20.
The opening 44 can have various shapes and sizes to enable the charger 49, which can have various configurations, to fit in the opening 44. For example, the opening 44 can be rectangular as depicted in
The outer surface 42 of the stand 40 preferably is configured to mate with a receptacle 50 defined in a body 52. The body 52 can be a console or other portion of an automobile, truck, bus, or other vehicle, for example. The receptacle 50 is preferably a vehicle cup holder designed to receive a cup, can, or other beverage container.
Accordingly, the stand 40 preferably can have various shapes and sizes that allow it to mate with different shaped and sized receptacles 50. As depicted in
The outer surface 42 of the stand 40 preferably includes a peripheral edge 56. The peripheral edge 56 can be angled outwardly as shown, or alternatively can have other configurations, such as that of a rim. The stand 40 can have a suitable height relative to the depth of the receptacle 50, such that a portion of the peripheral edge 56 contacts the surface 58 of the body 52 when the stand 40 is placed in the receptacle 50. In this position, the peripheral edge 56 can be grasped by a user to remove the stand 40 from the receptacle 50.
An electrical conductor 60 is connected to the charger 49 to electrically connect the internal power supply 62 of the electrically heated cigarette smoking device 10 to an external power source. The power supply 62 is connected to charging electronics 64 via wiring 66. The electrical conductor 60 preferably is adapted to mate with a socket 68 of the charger 49, such as the socket 24 depicted in
In a preferred embodiment, the charger 49 and the electrically heated cigarette smoking device 48 operate on direct current (DC). The stand 40 can be constructed to operate with DC power sources, such as vehicle batteries, that supply various voltages, such as 6, 9, 12 or 24 volt power sources.
In another preferred embodiment, the charger 49 includes inductive charging electronics and associated electrical elements that can convert DC from a DC power source to alternating current (AC), and convert the AC back to DC to charge the power supply 62 of the electrically heated cigarette smoking device 48. For example, an inductive field can be generated in the charger 49 by passing current through a coil. A matching coil can be provided in the charger 49 to produce AC. A diode and other suitable electronics can be provided in the charger 49 convert the AC to DC to charge the internal power supply 62.
Another preferred embodiment of the stand 140 is shown in
The stand 140 can include one or more fasteners (as described above) to allow removable or permanent attachment of the stand 140 to a surface.
As described above, the internal power supply of the electrically heated cigarette smoking device can be charged by supplying DC current directly from an external power source to the power supply, or alternatively the stand 140 can include inductive charging electronics for converting DC to AC and vice versa.
Another preferred embodiment of the stand 240 is shown in
The stand 240 can include one or more fasteners (as described above) to allow removable or permanent attachment of the stand 240 to a surface.
As described above, the internal power supply of the electrically heated cigarette smoking device can be charged by supplying DC current directly from an external power source to the power supply, or alternatively the stand 240 can include inductive charging electronics for converting DC to AC and vice versa.
Accordingly, preferred embodiments of the stand are suitable for use in a vehicle, as well as in other means of transportation. In addition, the stand can be configured to mate with receptacles provided in vehicles, and to be compatible with vehicle power sources. The stand provides for convenient storage and recharging of electrically heated cigarette smoking devices in such applications.
As described above, the stand preferably can be used with existing electrically heated cigarette smoking devices, or the stand can be configured to receive future designs of electrically heated cigarette smoking devices.
While the invention has been described in detail with reference to preferred embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made, and equivalents employed, without departing from the scope of the appended claims.
