Abstract:
A power generating electronic cigarette includes a partially hollowed body having an enclosed distal end, and a filter cartridge attached at a proximal end of the body. The cigarette operates using power stored within a portable power storage media integrated within the body. A power generating subassembly is located within the hollowed body, wherein the power generating subassembly generates an electrical current to charge the power storage media. The power generating subassembly utilizes motion of a magnet in proximity of a coil to generate an electrical current within the coil. The current can be converted into stored electrical power. Motion of the magnet can result from shaking or rolling the electronic cigarette. Alternately, the magnet can be rotated by an airflow driven device operated by airflow applied to the cigarette.

CROSS-REFERENCE TO RELATED APPLICATION 
     This Non-Provisional Utility application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/458,675, filed on Nov. 29, 2010, which is incorporated herein in its entirety. 
    
    
     FIELD OF THE INVENTION 
     The present disclosure generally relates to an electronic cigarette or any other inhaling device. More particularly, the present disclosure relates to an electronic cigarette comprising an integrated charging mechanism which generates electrical power which is stored within a portable power storage media for providing electrical power to the electronic cigarette during operation. 
     BACKGROUND OF THE INVENTION 
     An electronic cigarette, or e-cigarette, is an electrical device that simulates the act of tobacco smoking without burning tobacco. The electronic cigarette accomplishes this by producing an inhaled mist bearing the physical sensation and appearance of inhaled tobacco smoke. The device uses heat (or in some cases, ultrasonics) to vaporize a propylene glycol- or glycerin-based liquid solution into an aerosol mist, similar to the way a nebulizer or humidifier vaporizes solutions for inhalation. The primary stated use of the electronic cigarette is an alternative to tobacco smoking. 
     Most electronic cigarettes are portable, self-contained cylindrically shaped devices designed to resemble actual cigarettes, cigars, and the like. Most electronic cigarettes utilize reusable parts including replaceable and/or refillable components, whereas lower cost devices can be disposable. The sizes of the electronic cigarettes can vary to support different battery capacities. 
     The electronic cigarette includes three key components:
         a. A “cartridge”, which serves as a mouthpiece and usually, doubles as a small reservoir holding the liquid that is vaporized during use. The cartridge is normally replaceable.   b. An “atomizer”, which serves as a heating element responsible for vaporizing the liquid.   c. A power unit, which includes a portable power source and other electronic components necessary for operation. The portable power source is commonly a battery.       

     Each of the key components can be integrated into a single assembly or fabricated as separate subassemblies that are assembled together using electro-mechanical couplers. 
     The electronic cigarettes are commonly charged through a combination filter and charging electromechanical interface. The charging process requires an external power source and a charging cable. The use of the electronic cigarette dictates at least one of inclusion of a sufficient stored power capacity, remembering to adequately charge the electronic cigarette prior to use, and toting the external power source and a charging cable in order to ensure the electronic cigarette is available for use as desired. The current configuration becomes limiting when the individual desires to use the electronic cigarette and the stored power has been depleted. The process of recharging the electronic cigarette is limited, requiring the user to couple the charging cable to the external power source and wait until the unit obtains a sufficient charge for use. 
     What is desired is an electronic cigarette enabling recharging of an internal power storage device by simply shaking the electronic cigarette, passing an airflow across a charging element provided within the electronic cigarette, and applying an external driving element to an internally located charging element. 
     SUMMARY OF THE INVENTION 
     The basic inventive concept provides a power generating electronic cigarette. 
     A first aspect of the present invention provides a power generating electronic cigarette comprising:

Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise. 
     A power generating electronic cigarette  100 , in accordance with a first exemplary embodiment, is presented in  FIGS. 1 and 2 . The power generating electronic cigarette  100  is segmented in two components, an elongated electronic cigarette body  110  and a filter cartridge  150  which may take the form of a replaceable refill filter cartridge. The elongated electronic cigarette body  110  includes the power and non-consumable components of the power generating electronic cigarette  100 . The elongated electronic cigarette body  110  is fabricated of a hollow or partially hollow tubular structure which may have an electromechanical filter coupling element  119  assembled at a proximal end of the tubular structure of the elongated body  110  and an enclosed tip  112  which may take the form of an illuminating element assembled at a distal end of the tubular structure of the elongated body  110 . The tubular structure of the elongated electronic cigarette body  110  can be fabricated having an internal frame defining one or more cavities  116 ,  118  and a hollow external shell  111  that slides over the internal frame. The refill filter cartridge  150  provides the consumable components of the power generating electronic cigarette  100  in a form of a replaceable cartridge. The refill filter cartridge  150  is removably attached to the tubular structure of the elongated body  110  of the power generating electronic cigarette  100  via the electromechanical filter coupling element  119 . An illuminated tip cover  114  is assembled to the distal end of the elongated electronic cigarette body  110  covering the illuminating element of the enclosed tip  112 . The illuminated tip cover  114  can be clear or tinted, wherein the illuminated tip cover  114  is preferably fabricated of a translucent material having a red hue. The enclosed illuminating element tip  112  (such as a red light emitting diode (LED)) and illuminated tip cover  114  provides a burning effect during operation of the electronic cigarette  100 . 
     The power generating electronic cigarette  100  can be fabricated in any of a variety of configurations without deviating from the spirit and intent of the present invention. It is understood that the refill filter cartridge  150  can be integrated into the power generating electronic cigarette  100 , eliminating the electromechanical filter coupling element  119 . The power generating electronic cigarette  100  can be offered with either the electromechanical filter coupling element  119  or a filter cartridge located at a proximal end of the elongated electronic cigarette body  110 . The elongated electronic cigarette body  110  can be configured with or without the illuminating element of the enclosed tip  112 . The enclosed tip  112 , without the illuminating element tip, still will provide a barrier for moisture, contaminants, and the like. 
     The power generating electronic cigarette  100  requires power for operation. The currently offered products utilize a power storage media that is recharged by connecting a power charging cable (not shown) between the electromechanical filter coupling element  119  and a power source, such as a wall outlet, a vehicle power outlet, an external battery pack, and the like. This limitation dictates that the user carries the charging cable and has access to the respective power source in order to recharge the power storage media. The elongated electronic cigarette body  110  includes a power generating subassembly integrated within an electrical generator cavity  116  of the elongated electronic cigarette body  110 , wherein the power generating subassembly generates an electrical output when subjected to a charging shaking motion  198 . 
     The power generating subassembly creates an electrical power output to replenish electrical power stored within a portable power storage media  140 . The power generating subassembly includes a linearly moving magnet  130  slideably assembled within a coil inner passage  122  of an electrical coil  120 . The electrical coil  120  can span a portion or the entire length of the electrical generator cavity  116 . A coil lining  123  or any other non-magnetic sleeve (not shown) can be inserted between the coil inner passage  122  and the linearly moving magnet  130  to improve longevity of the elongated electronic cigarette body  110 , reduce friction between the linearly moving magnet  130  and the electrical coil  120 , and the like. 
     The linearly moving magnet  130  is shaped including a magnet exterior surface  132  terminating between a magnet first end  134  and a magnet second end  136 . The magnet exterior surface  132  is sized and shaped to slide within the coil inner passage  122 . 
     In operation, the user shakes the elongated electronic cigarette body  110  in accordance with a charging shaking motion  198 , wherein the charging shaking motion  198  is substantially parallel with a longitudinal axis  180  of the elongated electronic cigarette body  110 . The motion causes the linearly moving magnet  130  to move in accordance with a magnet sliding motion  196 . As the linearly moving magnet  130  slides through the coil inner passage  122 , the sliding motion of the linearly moving magnet  130  creates a current along the windings of the electrical coil  120 . The current can be converted into stored electrical power. 
     The portable power storage media  140  can be any portable electrical storage media, including a battery, a capacitor, and the like. The portable power storage media  140  and respective components can be assembled within a power storage cavity  118 . An electrically conductive material (not shown, but well understood by those skilled in the art) is provided between the electrical coil  120  and the portable power storage media  140 . In the exemplary embodiment, a first power contact  142  provides electrical communication with a first electrical terminal of the portable power storage media  140  and a second power contact  144  provides electrical communication with a second electrical terminal of the portable power storage media  140 . The circuit created by the electrical coil  120 , the electrically conductive material, the first power contact  142 , and the second power contact  144  provides a charging circuit to replenish electrical energy within the portable power storage media  140 . 
     A first dampening member  124  and a second dampening member  126  can be located proximate each respective end of the electrical generator cavity  116 . The dampening members  124 ,  126  decelerate the linearly moving magnet  130  as the linearly moving magnet  130  approaches each respective end of the electrical generator cavity  116 . The dampening members  124 ,  126  can be a coiled spring, a pliant material, a section of rubber, a section of silicon, a section of a sponge, an inflated element, and the like. 
     A power generating electronic cigarette  200 , in accordance with a second exemplary embodiment, is presented in  FIG. 3 . Similar to the power generating electronic cigarette  100 , the power generating electronic cigarette  200  is segmented in two components, an electronic cigarette body  210  and a replaceable refill filter cartridge  250 . Unless otherwise indicated, like features of power generating electronic cigarette  200  and power generating electronic cigarette  100  are numbered the same except preceded by the numeral ‘2’. 
     The power generating subassembly utilizes a rotating magnet  230  rotationally assembled within a coil inner channel  224  of the electrical coil  220 . One or more coil periphery magnets  222  are located about an outer periphery of the electrical coil  220 . A plurality of coil periphery magnets  222  can be spatially arranged about an external periphery of the electrical coil  220 . A magnet rotational axle  234  extends from a concentric location of the rotating magnet  230 , extending outward along a central longitudinal axis thereof. An airflow driven rotator  232  is affixed to the magnet rotational axle  234 , preferably at a proximal end thereof. The airflow driven rotator  232  is subjected to airflow  298 , causing the airflow driven rotator  232  to rotate in accordance with a charging rotational motion  296 . In turn, the charging rotational motion  296  of the airflow driven rotator  232  is transferred to the rotating magnet  230  via the magnet rotational axle  234 , causing the rotating magnet  230  to spin. The spinning motion generates a current through the electrical coil  220 . The current is passed through a portable power storage media  240  using a charging circuit similar to the charging circuit described above, which stores at least a portion of the generated electrical power. 
     In a modified version, the electrical coil  220  can be affixed to the rotating magnet  230 , wherein the electrical coil  220  is rotationally inserted within an interior channel formed within the coil periphery magnet or magnets  224 . The electrical coil  220  would spin in conjunction with the rotating magnet  230 , creating a current within the electrical coil  220 . 
     A power generating electronic cigarette  300 , in accordance with a third exemplary embodiment, is presented in  FIG. 4 . The illustration presents an enlarged view of the power generating subassembly of the power generating electronic cigarette  300 , omitting other functional components previously disclosed above. Similar to the power generating electronic cigarette  100 , the power generating electronic cigarette  300  is segmented in two components, an electronic cigarette body  310  and a replaceable refill filter cartridge. Unless otherwise indicated, like features of power generating electronic cigarette  300  and power generating electronic cigarette  100  are numbered the same except preceded by the numeral ‘3’. 
     The power generating subassembly utilizes an airflow driven actuator  360  in conjunction with at least one coil subassembly. The first exemplary coil subassembly includes a first linearly moving magnet  330  passing through a respective coil inner passage  322  of an electrical coil  320 . The first linearly moving magnet  330  can be described as having a cylindrical exterior shape  332  extending between a first magnet first end  334  and a first magnet second end  336 . The first linearly moving magnet  330  is slideably inserted within the respective coil inner passage  322  of the electrical coil  320 . It is understood that a non-magnetic tubular sleeve may be deployed within the first coil inner passage  322  for the same purposes as the sleeve described above. 
     The airflow driven actuator  360  includes a blade assembly comprising a plurality of blades extending radially outward from a blade axle  370 . The blade assembly can be positioned within a shroud interior  364  of an actuator shroud  362 . The blade axle  370  is rotationally assembled to the power generating subassembly. In the exemplary embodiment, the airflow driven actuator  360  includes bracket rotationally connecting the blade axle  370  to the actuator shroud  362 . At least one south magnetically polarized element  368  is carried by at least one of the blades  366 ,  376  of the blade assembly. In the exemplary embodiment, the blade assembly includes a south magnetically polarized element  368  carried by a south magnetic blade  366  and a north magnetically polarized element  378  carried by a north magnetic blade  376 . The blade assembly can include additional blades  369 ,  379 , which can either include or exclude magnets. In the exemplary embodiment, the south magnetically polarized element  368  is oriented polar opposite to the north magnetically polarized element  378 . 
     The exemplary power generating subassembly comprises a second coil assembly replicating the elements of the first coil assembly. The second coil is identified as a second electrical coil  321 , defining a first coil inner passage  323  passing through the windings of the second electrical coil  321 . The elements of the second linearly moving magnet  380  are the same as the elements of the first linearly moving magnet  330 , wherein like features are numbered the same except preceded by the numeral ‘38’. The first linearly moving magnet  330  and second linearly moving magnet  380  can be oriented with like polarities facing similar directions or opposite directions. 
     In operation, airflow  398  causes the blade assembly to rotate in accordance with a blade assembly rotational motion  396 . The blade assembly rotational motion  396  rotates the blade assembly passing the magnetically polarized elements  368 ,  378  across the linearly moving magnets  330 ,  380 . As opposite polarities of the magnetically polarized elements  368 ,  378  and the linearly moving magnets  330 ,  380  pass across one another, they attract, drawing the linearly moving magnets  330 ,  380  towards the airflow driven actuator  360  in accordance with an attracting motion  338 ,  388 . As like polarities of the magnetically polarized elements  368 ,  378  and the linearly moving magnets  330 ,  380  pass across one another, they repel, separating the linearly moving magnets  330 ,  380  from the airflow driven actuator  360  in accordance with a repelling motion  339 ,  389 . The motion of the linearly moving magnets  330 ,  380  passing across the coils  320 ,  321  creates a current within the coils  320 ,  321 . A circuit created by the electrical coils  320 ,  321 , electrically conductive material, and contacts, provides a charging circuit to replenish electrical energy within the portable power storage media. 
     It is understood that the linearly moving magnets  330 ,  380  can be arranged with like polarities oriented in like direction causing the linearly moving magnets  330 ,  380  to move in opposite directions. Similarly, the linearly moving magnets  330 ,  380  can be arranged with like polarities oriented in opposite direction causing the linearly moving magnets  330 ,  380  to move in a parallel relation to each other. 
     The exemplary power generating subassembly can be modified utilizing magnetically polarized elements  368 ,  378  oriented with like polarities in like directions. A biasing member can be provided in communication with the linearly moving magnets  330 ,  380 . The magnetically polarized elements  368 ,  378  either attract or repel the linearly moving magnets  330 ,  380  based upon the orientation of the polarities of the magnetic components. The interactive force between the magnetically polarized elements  368 ,  378  and the linearly moving magnets  330 ,  380  overcomes a biasing force generated by the biasing member. When the blade assembly rotates removing the interactive force between the magnetically polarized elements  368 ,  378  and the linearly moving magnets  330 ,  380 , the biasing force returns the linearly moving magnets  330 ,  380  to a normal position. The biasing member can be a coil spring, a linear spring, and the like. When the magnetically polarized elements  368 ,  378  are oriented to attract the linearly moving magnets  330 ,  380 , the biasing member would be designed to separate the magnetically polarized elements  368 ,  378  and the linearly moving magnets  330 ,  380 . When the magnetically polarized elements  368 ,  378  are oriented to repel the linearly moving magnets  330 ,  380 , the biasing member would be designed to bring the magnetically polarized elements  368 ,  378  and the linearly moving magnets  330 ,  380  together. 
     A power generating electronic cigarette  400 , in accordance with a fourth exemplary embodiment, is presented in  FIG. 5 . Similar to the power generating electronic cigarette  100 , the power generating electronic cigarette  400  is segmented in two components, an electronic cigarette body  410  and a replaceable refill filter cartridge  450 . Unless otherwise indicated, like features of power generating electronic cigarette  400  and power generating electronic cigarette  100  are numbered the same except preceded by the numeral ‘4’. 
     The power generating electronic cigarette  400  incorporates a power generating subassembly integrated within an electrical generator cavity  416  of the electronic cigarette body  410 , wherein the power generating subassembly generates an electrical output when subjected to an externally moving magnet or series of magnets. 
     The power generating subassembly creates an electrical power output to replenish electrical power stored within a portable power storage media  440 . The power generating subassembly includes a rotating magnetic sphere  430  rotationally assembled within a coil interior portion  422  of an electrical coil  420 . The electrical coil  420  is sized to retain the rotating magnetic sphere  430  from moving along the longitudinal axis of the electronic cigarette body  410 . A non-magnetic sleeve (not shown) can be inserted within the coil interior portion  422  or placed about the rotating magnetic sphere  430  to improve longevity of the electronic cigarette body  410 , reduce friction between the rotating magnetic sphere  430  and the electrical coil  420 , and the like. Although the exemplary rotating magnetic sphere  430  is a sphere, it is understood that the rotating magnetic sphere  430  can be provided in any acceptable shape, such as a cylinder. 
     A wireless power actuator  460  is provided to magnetically interact with the rotating magnetic sphere  430 , driving a magnetic sphere rotational motion  496  of the rotating magnetic sphere  430 . The wireless power actuator  460  is fabricated having one or more magnets  470 ,  472 ,  474  carried by a power actuator casing  462 . In operation, the wireless power actuator  460  is locate proximate the electrical coil  420  and rotated about a power actuator central axis  464 . The wireless power actuator  460  can be rotated in either a clockwise rotation  498  or a counterclockwise rotation  499 . The rotational motion  498 ,  499  of the wireless power actuator  460  interacts with the rotating magnetic sphere  430 , causing the magnetic sphere rotational motion  496  of the rotating magnetic sphere  430 . As the rotating magnetic sphere  430  rotates within the coil interior portion  422 , the rotating motion of the rotating magnetic sphere  430  creates a current along the windings of the electrical coil  420 . The current can be converted into stored electrical power. 
     Alternately, an optional coil periphery magnet  424  can be integrated about an external surface of the electrical coil  420 . The coil periphery magnet  424  can be fixed or rotationally assembled therein. The power generating subassembly can be configured enabling the coil periphery magnet  424  to rotate in conjunction with the rotational motion  498 ,  499  of the wireless power actuator  460 . The motion of the coil periphery magnet  424  generates a current along the windings of the electrical coil  420 . 
     The electrical coils  120 ,  220 ,  320 ,  321 ,  420  can be fabricated using any common coil materials, including copper wire, and the like. The coil wire is preferably coated with an insulating material. The electrical coils can be encapsulated with any reasonable material. A non-magnetic and non-conductive material can be placed covering an interior surface, an exterior surface, or both surfaces of the coil windings. 
     It is understood that a voltage or charging regulation circuit can be integrated within the charging circuits described above. 
     Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalence.
