Definitions

  • the present invention relates generally to electronic smoking devices and in particular electronic cigarettes as well as cartomizers and liquid reservoirs for electronic smoking devices.
  • An electronic smoking device such as an electronic cigarette (e-cigarette) typically has a housing accommodating an electric power source (e.g. a single use or rechargeable battery, electrical plug, or other power source), and an electrically operable atomizer.
  • the atomizer vaporizes or atomizes liquid supplied from a reservoir and provides vaporized or atomized liquid as an aerosol.
  • Control electronics control the activation of the atomizer.
  • an airflow sensor is provided within the electronic smoking device which detects a user puffing on the device (e.g., by sensing an under-pressure or an air flow pattern through the device). The airflow sensor indicates or signals the puff to the control electronics to power up the device and generate vapor.
  • a switch is used to power up the e-cigarette to generate a puff of vapor.
  • Some electronic smoking devices comprise a cartomizer which is a replaceable unit comprising the atomizer and the reservoir for the liquid.
  • a cartomizer which is a replaceable unit comprising the atomizer and the reservoir for the liquid.
  • a liquid reservoir for an electronic smoking device comprises a body forming a hollow tube surrounding a central passage connecting ports for attaching the liquid reservoir to further portions of the electronic cigarette.
  • the liquid reservoir further comprises a nozzle towards the central passage, the nozzle being configured to release liquid from the liquid reservoir only when pressure drop along the nozzle exceeds a threshold pressure.
  • the body defines a hollow cylindrical body closed on one end with a plate, which forms the nozzle. The plate is slidable with the movement of a piston for causing compression of the liquid reservoir.
  • a user can produce the pressure drop by manually changing a length of the central passage thereby causing compression of the liquid reservoir. The user may increase the pressure drop by sucking at an inhalation port of the electronic smoking device.
  • an electronic smoking device typically has a housing comprising a cylindrical hollow tube having an end cap 16.
  • the cylindrical hollow tube may be single piece or a multiple piece tube.
  • the cylindrical hollow tube is shown as a two piece structure having a battery portion 12 and an atomizer/liquid reservoir portion 14. Together the battery portion 12 and the atomizer/liquid reservoir portion 14 form a cylindrical tube which is approximately the same size and shape as a conventional cigarette, typically about 100 mm with a 7.5 mm diameter, although lengths may range from 70 to 150 or 180 mm, and diameters from 5 to 20 mm.
  • the battery portion 12 and atomizer/liquid reservoir portion 14 are typically made of steel or hardwearing plastic and act together with the end cap 16 to provide a housing to contain the components of the e-cigarette 10.

  • the coil 28 may be positioned anywhere in the atomizer 26 and may be transverse or parallel to the liquid reservoir 34.
  • the wick 30 and heating coil 28 do not completely block the central passage 32. Rather an air gap 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 may alternatively use other forms of heating elements, such as ceramic heaters, or fiber or mesh material heaters. 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 cylindrical liquid reservoir 34 with the ends of the wick 30 abutting or extending into the liquid reservoir 34.

  • This causes air to be drawn into the e-cigarette 10 via one or more air inlets, such as air inlets 38 and to be drawn through the central passage 32 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 central passage 32.
  • this aerosol is drawn through the central passage 32 and inhaled by the user.
  • 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 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.
  • liquid present in the wick 30 is converted into an aerosol more liquid is drawn into the wick 30 from the liquid reservoir 34 by capillary action and thus is available to be converted into an aerosol through subsequent activation of the heating coil 28.

  • a replaceable unit comprising the atomizer 26 and the liquid reservoir 34 is called a cartomizer.
  • the new liquid reservoir 34 may be in the form of a cartridge having a central passage 32 through which a user inhales aerosol.
  • aerosol may flow around the exterior of the cartridge 32 to an air inhalation port 36.
  • 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 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.
