초록 ▼

An electronic cigarette has a vaporizer to produce vapor to be delivered to its mouth end. The vaporizer includes a tube having inlet and outlet ends. A porous matrix containing a vaporizable liquid, extends around the tube. Wicking fibers extend through side openings in the tube and are configured to wick the vaporizable liquid from the porous matrix into the tube, and electrical heater coil is powered by a battery to vaporize liquid on the wicking fibers in the tube, so that vapor is supplied along the tube end when the user draws on mouth end. The wicking diverge from the openings into fan shaped spread regions around outer surface of the tube so as to contact and receive the vaporizable liquid by capillary action from the matrix.

대표청구항 ▼

1. An electronic cigarette comprising a generally cylindrical housing with a proximal mouth end and a distal end, and within the housing: a vaporizer to produce vapor to be delivered to the mouth end;a battery; andsensor circuitry to detect a user drawing on the mouth end and connect the battery to power the vaporizer to produce vapor,the vaporizer comprising: a tube having inlet and outlet ends and extending longitudinally of the housing,supports at opposite ends of the tube for directing airflow into and out of the tube from the inlet to the outlet,a vaporizable liquid holder containing a vaporizable liquid extending around the tube,wicking fibers extending through side openings in the tube and configured to wick the vaporizable liquid from the vaporizable liquid holder into the tube, andan electrical heater coil in the tube configured to be powered by the battery to vaporize liquid on the wicking fibers in the tube, so that vapor is supplied along the tube to the outlet end when the user draws thereon,wherein the wicking fibers diverge from one another from the side openings and are spread over the outer surface of the tube so as to contact and receive the vaporizable liquid by capillary action from the matrix. 2. An electronic cigarette according to claim 1 wherein the spread wicking fibers lie spread over the outer surface of the tube in an arc which at its outermost spread subtends an angle (θ) at the central longitudinal axis of the tube of at least 30°. 3. An electronic cigarette according to claim 1 wherein the spread wicking fibers lie spread over the outer surface of the tube in an arc which at its outermost spread subtends an angle (θ) at the central longitudinal axis of the tube having a value in the range 40°-150°. 4. An electronic cigarette according to claim 1 wherein the spread wicking fibers extend towards the inlet end of the tube. 5. An electronic cigarette according to claim 1 wherein the spread wicking fibers extend towards the outlet end of the tube. 6. An electronic cigarette according to claim 1 wherein the wicking fibers emanating from at least one of the side openings are configured in first and second bundles which are spread in different directions along the tube. 7. An electronic cigarette according to claim 1 wherein the supports include a mouth end stopper that is push-fitted into the mouth end of the housing, the mouth end stopper including a mouthpiece spigot onto which the outlet end of the tube is received, and an outlet passageway extending through the spigot to provide an outlet for vapor from the tube. 8. An electronic cigarette according to claim 7 including a gap between the vaporizable liquid holder and the mouth end stopper. 9. An electronic cigarette according to claim 1 wherein the supports include an annular support member including a peripheral surface to engage with an interior of the housing, an inlet spigot on which the outlet end of the tube is mounted, and an inlet passageway extending through the inlet spigot to provide an inlet for air into the tube. 10. An electronic cigarette according to claim 8 wherein the annular support member includes a depending peripheral flange such that the vaporizable liquid holder is retained between the mouth end stopper and the flange. 11. An electronic cigarette according to claim 10 wherein ends of the wicking fibers are retained sandwiched between the tube and the vaporizable liquid holder between the spigot and the flange. 12. An electronic cigarette according to claim 9 including a washer between the annular support member and the battery. 13. An electronic cigarette according to claim 1 including an air inlet opening at the distal end of the housing. 14. An electronic cigarette according to claim 13 including an air feed passageway between the battery and the housing, extending from the air inlet opening to the inlet end of the tube. 15. An electronic cigarette according to claim 1 wherein the sensor circuitry is disposed between the battery and the distal end of the housing. 16. An electronic cigarette according to claim 1 including a light source powered by the battery under the control of the sensor circuitry to be illuminated in response to the user drawing on the mouth end. 17. An electronic cigarette according to claim 16 wherein the light source is disposed at the distal end of the housing. 18. An electronic cigarette according to claim 1 including an end cap push-fitted into the distal end of the housing. 19. An electronic cigarette according to claim 1 wherein the housing comprises a first part containing the battery releaseably coupled to a second part containing the vaporizer. 20. An electronic cigarette according to claim 1 wherein the vaporizable liquid holder comprises inner and outer sheets of overlying fibrous material with the outer sheet having a greater pore size than the inner sheet for wicking the liquid to the inner sheet by capillary action. 21. An electronic cigarette according to claim 1 including an atomization aperture in the tube configured to allow liquid to be drawn into the tube from the vaporizable liquid holder so as to be atomized by passage through the aperture when the user draws on the mouth end.
