Definitions
- the present invention relates to electronic cigarettes. More specifically, the present invention relates to an electronic cigarette with an internal liquid reservoir.
- Electronic cigarettes have become increasingly popular in recent times. Electronic cigarettes emulate a tobacco cigarettes, but without the combustion of tobacco during use. Rather than burning tobacco, a liquid is atomized within the electronic cigarette, which emulates the smoke produced in a tobacco cigarette.
- the liquid may contain flavoring agents such as tobacco flavor, menthol, and others, to enhance the “smoking” experience of the electronic cigarette. Nicotine has been added to the atomization liquid in prior art electronic cigarettes.
- a reserve of liquid is stored within the cigarette housing in a porous material, which is placed into contact with an atomizing assembly such that the liquid can be gradually transferred to the atomizing assembly during consumption.
- a replaceable cartridge with a liquid soaked porous material has been provided to enable consumers to replenish the supply of liquid as it is depleted during use by replacing the cartridge. It should be appreciated that the structural and electrical components in an electronic cigarette are durable and outlast, by a long measure, the period of consumption for the quantity of liquid provided in such a porous reservoir.
- the present invention teaches an electronic cigarette apparatus including an elongated housing that has a mouthpiece with an aerosol outlet, and an atomizer disposed within an atomizing chamber.
- the atomizer selectively generates an aerosol of the liquid in response to suction pressure at the aerosol outlet.

- the foregoing apparatus further includes an inlet vent formed on the exterior of the elongated housing that is coupled to deliver air to the atomizing chamber air inlet.
- the inlet vent is coupled to the atomizing chamber air inlet by a conduit.
- the conduit sealably passes through the liquid reservoir.
- the atomizer outlet and the aerosol outlet are coupled together by a chimney.
- the chimney sealably passes through the liquid reservoir.

- the wick is partially engages the resistive heating element.
- the atomizer has a tubular form defining an open central passage.
- the wick passes through the open central passage.
- the atomizing chamber further includes a second wick aperture, and the apparatus is arranged such that a first end of the wick passes through the first wick aperture and a second end of the wick passes through the second wick aperture.
- the wick is fabricated as a bundle of heat resistant fibers.
- the bundle of heat resistant fibers is fiberglass.
- the bundle of heat resistant fibers is fabricated from a material selected from; aramid, fluorocarbon, sulfide, melamine, polyimide, carbon, and glass.
- the liquid reservoir is formed as an annular cavity between the interior of the elongated housing and the atomizing chamber.
- the liquid reservoir includes an external access opening, for enabling addition of liquid into the liquid reservoir.
