Problems solved by technology

[0006] However, since the desired vapor droplet size in aerosols is very small, the mesh still does not give satisfactory results
Even if the opening in the mesh is reduced, the associated flow restriction increases and satisfactory vapor flow from the nozzle remains difficult to achieve

example 1

[0069] Diameter: 0.4mm

[0070] Resistance length: 70mm

[0071] Resistance: 0.294Ω

[0072] Total effective length: 68mm

[0073] Pitch: 0.7mm

[0074] Heating coil height: 4.75mm

[0075] Total effective surface: 85.45mm2

[0076] Power density: 0.187W / mm2

[0077] Heated convection: 1040W / m2K

[0078] Height of fluid transfer element: 5.8mm

[0079] Additionally, the liquid inlet to the fluid transfer element 38 is enlarged in the axial direction of the fluid transfer element 38 in order to provide a sufficient supply of liquid along the entire length of the heater element 36 .

[0080] However, the first exemplary balloon provided unsatisfactory results, although the liquid supply to the heater element 36 and saturated fluid transfer element 38 was adequate and evenly distributed. The coils exhibited an inconsistent heating curve where the lower part of the heating coil only reached 300K while the upper part of the coil reached about 900K. Since the total measurab...

Abstract

A capsule (16) for an electronic cigarette is disclosed, the capsule having a first end for engaging with an electronic cigarette device and a second end configured as a mouthpiece portion (28) havinga vapor outlet, the capsule further comprising: a liquid store (32) configured to contain a liquid L to be vaporized, a vaporizing unit (34) comprising a heater (36) and a fluid transfer element (38), the vaporizing unit being arranged within a vaporizing chamber (30), a main vapor channel (24) extending from the vaporizing chamber to the vapor outlet in the mouthpiece, and a housing enclosing the liquid store and the vaporizing unit, wherein the fluid transfer element (38) is fluidly connected to the liquid store by at least one liquid inlet (48) and the fluid transfer element provides a capillary action on liquid received therein, wherein the heater (36) is provided at a position that is substantially adjacent the liquid inlet (48), or at a position between the liquid inlet and the mouthpiece (28).

Description

technical field [0001] The present invention relates to personal vaporizing devices, such as electronic cigarettes. In particular, the present invention relates to an electronic cigarette and a disposable capsule therefor. Background technique [0002] E-cigarettes are an alternative to regular cigarettes. Instead of producing combustion aerosols, e-cigarettes vaporize a liquid that can be inhaled by the user. Liquids typically include aerosol-forming substances such as glycerin or propylene glycol which generate vapors. Other common substances in the liquid are nicotine and a variety of different flavors. [0003] Electronic cigarette is a hand-held inhaler system, including a nozzle part, a liquid reservoir, and a power supply unit. Vaporization is achieved by a vaporizer or heater unit which typically includes a heating element in the form of a heating coil and a fluid transfer element. Vaporization occurs as the heater heats the liquid in the wick until the liquid c...
