Definitions

  • the present invention relates to a battery-operated electronic cigarette for supplying vaporized nicotine or other materials to a user for simulating the act of smoking.
  • an electronic cigarette is provided in two sections.
  • the first section is a reusable generally cylindrical barrel containing the electrical components, including inter alia a rechargeable battery and heater.
  • the second section is a generally cylindrical member including a replaceable and disposable cartridge having the desired volatile material therein.
  • the second section is sealably coupled to the first section in axial alignment to form the completed electronic cigarette.
  • the first section provides heated air when the user draws air through a mouthpiece at the end of the disposable cartridge remote from the first section. The heated air flows through the volatile material, providing vaporized nicotine or other inhalant for consumption by the user.
  • the first section includes a heater coupled to the battery supply through an electrical control circuit controlled by a flow or pressure sensor, such that the heater is instantly and momentarily actuated upon inhaling by the user.
  • FIG. 1 is a diagram in schematic form of a prior art electronic cigarette
  • Fig. 2 is a diagram in schematic form of the electronic cigarette of the present invention.
  • Fig. 1 is representative of prior art electronic cigarettes with a power head 10 and a replaceable aerosol chamber 12.
  • the aerosol chamber 12 includes an atomizer, which is directly in communication with a nicotine supplying bottle that, in turn, supplies nicotine to the user through the mouthpiece when the user inhales on the mouthpiece.
  • This prior art represents a two-part electronic cigarette with a power head which is reusable using a rechargeable lithium battery and the aerosol chamber with an atomizer and source of material to be vaporized which must be replaced at frequent intervals with replacement cartridges.
  • a sealed coupling couples the power head to an aerosol chamber.
  • the aerosol is typically formed by a heater in contact with the source of volatile material.
  • FIG. 2 there is shown the electronic cigarette 15 embodying the present invention, which includes a first generally cylindrical section 20 and a second generally cylindrical section 30.
  • the first section 20 houses a rechargeable electrical power source, such as a lithium ion battery 21, and, at its outer end, an LED 23 and lens to simulate a lighted cigarette.
  • a microprocessor 24 is coupled to battery 21 and receives control signals from a conventional pressure or flow sensor 25 when an individual inhales through mouthpiece 38 at the end of the remote end of the second section 30.
  • the microprocessor couples battery 21 to a heater 26 when flow sensor 25 detects the flow of incoming air through air intake apertures 28 formed through the wall of first section 20 near sensor 25.
  • the heater is, in one embodiment, a resistance wire heater made of nichrome wire formed in a mesh to provide instant heat once power is applied.
  • the mesh design allows a significant flow of heated air at a temperature of from about 140°C to about 200°C when a user draws on the mouthpiece 38.
  • This heated airstream is represented at 27.
  • Microprocessor 24 is also coupled by conductors 22 to LED 23 to illuminate LED 23 when a user inhales, thereby providing the illusion of a lighted cigarette.
  • a sealed bayonet coupling 29 extends between sections 20 and 30, such that the replaceable second section 30 can be easily periodically replaced.
  • the first section 20 includes a suitable recharging connector (not shown), such that the battery 21 can be recharged on a plug-in stand coupled to an AC supply, such that it can be reused multiple times.
  • Section 20 is generally cylindrical and can be made of a durable material, such as stainless steel, aluminum, a polymeric material, or other suitable material.
  • the second section 30 is sealed at both ends and includes a cartridge 32 with a material to be vaporized.
  • the end 33 facing section 20 has a seal which is pierced when the two sections are joined at coupling 29 while the mouthpiece 38 has a peel-away seal.
  • the mouthpiece 38 may be integral with the second section or a separately attached member.
  • the cartridge likewise may be a separate element with peel-away seals at opposite ends which, when peeled away, is inserted in the second section 30.
  • the second section includes the cartridge and mouthpiece, and the end of the first section 20 facing the second section end 33 includes a projection (not shown) which pierces the seal at the proximate end of the second section 30.
  • O-rings 34 and 36 seal the cartridge 32 within section 30, such that the heated stream of air 27 flows through the cartridge and then is exhausted through mouthpiece 38 carrying the active ingredients from the cartridge to the user.
  • the cartridges 32 are packed with synthetic cotton fiber or other wicking material saturated with a mixture of polyethylene glycol, nicotine, water, and, if desired, a flavorant such as menthol or the like, in an azeotropic mixture.
  • a mixture of polyethylene glycol, nicotine, water, and, if desired, a flavorant such as menthol or the like in an azeotropic mixture.
  • Other volatile mixtures including, for example, glycerin, could be employed including various medicaments.
  • the cartridge 32 provides usage of from about 150 to about 200 puffs in one embodiment.
  • the heated air 27 flowing from heater 26 effects the vaporization of the nicotine in cartridge 32, which then flows through mouthpiece 38 to the user.
  • the cartridge 27 is in axially spaced- apart relationship to the heater 26, such that the heater does not become contaminated by the material to be vaporized and has a significantly longer useful lifetime than electronic cigarettes in which the heater is in direct or wicking contact with the substance to be vaporized. Also, the flow through cartridges 32 are relatively inexpensive and readily available.
  • the casing for the second or cartridge section 30 typically will be made of a high density polymer, such as polyethylene or polyacetate, to withstand the temperatures involved and provide the user with a comfortable holding surface for the device during use.
  • the overall shape and size of the electronic cigarette 15 is about that of a conventional cigarette and holder.
  • the cartridges 32 may be positioned in the second section 30 with a different sealing arrangement than that shown in Fig. 2 as long as the axial flow of heated air 27 transfuses the cartridge 32.

Abstract

Une cigarette électronique comporte une première section, qui prend la forme d'un tube réutilisable abritant des composants électriques et qui comprend une batterie rechargeable et un élément chauffant. Une seconde section est couplée de façon hermétique audit tube et forme une cartouche jetable remplaçable contenant une substance volatile. La première section fournit de l'air chauffé lorsque l'utilisateur aspire l'air par un embout situé à l'extrémité de ladite cartouche jetable. Cet air chauffé traverse la substance volatile, fournissant de la nicotine vaporisée ou un autre inhalant destinés à être consommés par l'utilisateur. La première section comporte un élément chauffant couplé à la batterie par le biais d'un circuit de commande électrique commandé par un détecteur de flux, de manière à ce que l'élément chauffant soit activé par l'action d'inhalation de l'utilisateur. Puisque la source d'air chauffé est séparée de la cartouche contenant la substance volatile, la fabrication de la cartouche remplaçable est beaucoup moins coûteuse, et le produit ainsi obtenu est plus efficace et de meilleure qualité.
