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 measurabl...

[0091] Diameter: between 0.226 and 0.3mm, preferably 0.254mm

[0092] Resistance length: 26.92mm

[0093] Resistance: between 0.291 and 0.295Ω

[0094] Total effective length: 26.09mm

[0096] Heating coil height: between 2.4-3.2mm

[0097] Total effective surface: 20.82mm2

[0098] Power density: between 1.152 and 2.319Watt / mm2, preferably 1.152Watt / mm2

[0101] Capillary height of the fluid transfer element: equal to or exceed the actual height of the fluid transfer element

[0102] Seal Type: It was shown that a non-circular seal with a height greater than width is most beneficial in maintaining negative pressure in the liquid reservoir 32 .

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 having a vapor outlet, the capsule further comprising: a liquid store 32 configured to contain a liquid Lto 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 heater is a heating coil with a height corresponding to 25% -50% of the height of the fluid transfer element, wherein the power density of the heater is between 4000and 7000 W/m2K, and the power density is between 1.10 to 2.350 Watt/mm2.

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...
