  • the battery 18 is electrically connected to the control electronics 22, which are electrically connected to the LED 20 and the airflow sensor 24.
  • the LED 20 is at the front end of the battery portion 12, adjacent to the end cap 16 and the control electronics 22 and airflow sensor 24 are provided in the central cavity at the other end of the battery 18 adjacent the atomizer 26.
  • the airflow sensor 24 acts as a puff detector, detecting a user puffing or sucking on the mouthpiece/liquid reservoir portion 14 of the e-cigarette 10.
  • the airflow sensor 24 can be any suitable sensor for detecting changes in airflow or air pressure, such as a microphone switch including a deformable membrane which is caused to move by variations in air pressure.
  • the sensor may be a Hall element or an electromechanical sensor.
  • the control electronics 22 are also connected to an atomizer 26.
  • the atomizer 26 includes a heating coil 28 which is wrapped around a wick 30 extending along a central passage 32 of the mouthpiece/liquid reservoir portion 14.
  • the heating coil 28 is positioned anywhere in the atomizer 26 and in the embodiment presented in figure 1 is transverse to the liquid reservoir 42.
  • the wick 30 and heating coil 28 do not completely block passage 46, that is provided on either side of the heating coil 28 enabling air to flow past the heating coil 28 and the wick 30. Rather, the passage or air gap 46 is provided on either side of the heating coil 28 enabling air to flow past the heating coil 28 and the wick 30.
  • the atomizer 26 may alternatively use other forms of heating elements, such as ceramic heaters, or fiber or mesh material heaters that may not necessarily be disposed transverse to the liquid reservoir.
  • Nonresistance heating elements such as sonic, piezo and jet spray may also be used in the atomizer in place of the heating coil.
  • the central passage 32 is surrounded by a liquid reservoir 42 with the ends of the wick 30 abutting or extending into the liquid reservoir 42 in the central passage 32.
  • the wick 30 may be a porous material such as a bundle of fiberglass fibers, with liquid in the liquid reservoir 42 drawn by capillary action from the ends of the wick 30 towards the central portion of the wick 30 in contact with the heating coil 28.
  • the liquid reservoir 42 may alternatively include wadding soaked in liquid which encircles the central passage 32 with the ends of the wick 30 abutting the wadding.
  • the liquid reservoir 42 may comprise a toroidal cavity arranged to be filled with liquid and with the ends of the wick 30 extending into the toroidal cavity.
  • the liquid reservoir is sealed with a porous cap, the cap coming into contact with a heating element or wick from a heating element.
  • the liquid reservoir and the mouthpiece have a cross sectional geometry that allows air to pass over the liquid reservoir.
  • An air inhalation port 36 is provided at the back end of the mouthpiece/liquid reservoir portion 14 remote from the end cap 16.
  • the inhalation port 36 may be formed directly into and from the mouthpiece/liquid reservoir portion 14 or may be formed in an end cap.
  • a user sucks on the e-cigarette 10.
  • This causes air to be drawn into the e-cigarette 10 via one or more air inlets, such as air inlet 38, and to be drawn through the passage 46.
  • the air flow splits by 90 degrees when it arrives at the heating element from where it travels to the outsides of the device to go around the liquid reservoir towards the air inhalation port 36.
  • the change in air pressure which arises is detected by the airflow sensor 24, which generates an electrical signal that is passed to the control electronics 22.
  • the control electronics 22 activate the heating coil 28, which causes liquid present in the wick 30 to be vaporized creating an aerosol (which may comprise gaseous and liquid components) within the passage 46.
  • the control electronics 22 also activate the LED 20 causing the LED 20 to light up which is visible via the translucent end cap 16 mimicking the appearance of a glowing ember at the end of a conventional cigarette.
  • the LED may be located below the snapping mechanism of the mouthpiece/liquid reservoir 14 and battery/atomizer portion 12, rather than at the end of the device, as shown in figure 1 .
  • the LED conveys to the user that their device is working properly. As liquid present in the wick 30 is converted into an aerosol more liquid is drawn into the wick 30 from the liquid reservoir 42 by capillary action and thus is available to be converted into an aerosol through subsequent activation of the heating coil 28.
  • e-cigarettes are known that are intended to be disposable and the electric power in the battery 18 is intended to be sufficient to vaporize the liquid contained within the liquid reservoir 42, even after which the e-cigarette 10 is thrown away. This is not the case with the e-cigarette of the present invention.
  • the battery 18 is rechargeable and the liquid reservoir 42 is refillable or exchangeable.
  • the mouthpiece/liquid reservoir portion 14 of the e-cigarette 10 is detachable from the battery/atomizer portion 12 and a new mouthpiece/liquid reservoir portion 14 can be fitted with a new liquid reservoir 42 thereby replenishing the supply of liquid.

  • aerosol may flow around the exterior of the cartridge 42 to an air inhalation port 36.
  • the air passages 46 may alternatively be formed as a central passage around which the liquid reservoir 42 is arranged.
  • the LED 20 may be omitted.
  • the airflow sensor 24 may be placed adjacent the end cap 16 rather than in the middle of the e-cigarette.
  • the airflow sensor 24 may be replaced with a switch which enables a user to activate the e-cigarette manually rather than in response to the detection of a change in air flow or air pressure.
  • the atomizer may have a heating coil in a cavity in the interior of a porous body soaked in liquid.
  • aerosol is generated by evaporating the liquid within the porous body either by activation of the coil heating the porous body or alternatively by the heated air passing over or through the porous body.
  • the atomizer may use a piezoelectric atomizer to create an aerosol either in combination or in the absence of a heater.
