Definitions

• the present disclosure relates to a mouthpiece for an aerosol-generating system.
• the present disclosure further relates to an aerosol-generating system.
• the high retention material may be arranged at a tip region of the hollow cone- shaped guiding member.
• the one or more capillary wicks may be arranged to contact liquid held in the liquid storage portion.
• the one or more capillary wicks may extend into the liquid storage portion.
• liquid may be transferred from the liquid storage portion to the one or more elements of the aerosol-generating means by capillary action in the one or more capillary wicks.
• the one or more capillary wicks may have a first end and a second end. The first end may extend into the liquid storage portion to draw liquid aerosol-forming substrate held in the liquid storage portion into the aerosol generating means.
• airflow path denotes a channel suitable to transport gaseous media.
• An airflow path may be used to transport ambient air.
• An airflow path may be used to transport an aerosol.
• An airflow path may be used to transport a mixture of air and aerosol.
• the mouthpiece and the main unit may have corresponding structural components with complementary geometrical shapes.
• the structural components with complementary geometrical shapes are preferably provided at adjacent interface portions of the mouthpiece and the main unit. Upon assembly of the mouthpiece and the main unit, these interface portions may be located next to each other.
• these corresponding structural components of the mouthpiece and the main unit may define an airflow path from an air inlet to the air outlet via the atomizer or heating element.
• the airflow path may be formed upon assembly of the main unit and the mouthpiece.
• the main unit may be rendered inoperable, since no continuous airflow path for inhaling an aerosol is provided. Thereby, the main unit alone does not allow for formation of an aerosol suitable for inhalation. Thereby, an efficient protection mechanism against unauthorized use may be provided.
• Example K The mouthpiece according to Example J, wherein the high retention material is arranged at a tip region of the hollow cone-shaped guiding member.
• Example N An aerosol-generating system, comprising a mouthpiece according to any of the preceding examples; a main unit comprising an atomizer; and an airflow path of the system extending from an air inlet via the atomizer to the airflow path of the mouthpiece; wherein the cone-shaped guiding member is configured to guide liquid components condensed from the airflow in a direction towards the atomizer.
• Example P The aerosol-generating system according to Example O, wherein the main unit comprises a main body and a replaceable cartridge, the main body comprising control electronics and a power supply; and the cartridge comprising the atomizer and the liquid storage portion; wherein the mouthpiece is attached to the cartridge and wherein the cartridge is attached to the main body.
• Fig. 1 shows a cross-section of a generally cylindrically shaped aerosol-generating system comprising a replaceable mouthpiece 10 and a main unit 40 in a detached configuration.
• the replaceable mouthpiece 10 shown in Fig. 1 comprises an optional bowl-shaped wall element 12 and an optional high retention material 13, both of which are omitted in the embodiment of Fig. 2.
• the replaceable mouthpiece 10 comprises air inlets 14 and an open chamber part 16.
• the replaceable mouthpiece 10 comprises a hollow element.
• the hollow element is a hollow tubular element 18.
• the hollow element may as well be of a different shape, for example a hollow truncated cone or a hollow cuboid, as long as the airflow route (as described below) will not be blocked.
• the hollow tubular element 18 comprises a conical end portion 20, a tube inlet opening 22, and a tube outlet opening 24.
• the tube outlet opening 24 is in direct fluid connection with an annular homogenization chamber 26.
• the bowl-shaped wall element 12 is located within the homogenization chamber 26 at distal portion thereof.
• the mouthpiece 10 further comprises a cone-shaped guiding member 28 with apertures 30.
• a longitudinal axis of the cone-shaped guiding member 28 is arranged in parallel to a longitudinal axis of the mouthpiece 10.
• the longitudinal axis of the cone-shaped guiding member 28 is arranged in parallel to a longitudinal axis of the aerosol-generating system.
• a base of the cone-shaped guiding member 28 is directed towards a proximal end of the mouthpiece 10 and, at the same time, of the aerosolgenerating system.
• the cone-shaped guiding member 28 is hollow circumscribing an empty interior space 32.
• the hollow cone-shaped guiding member 28 thus divides the airflow path of the mouthpiece 10 into a downstream airflow chamber arranged within the hollow cone-shaped guiding member 28 and an upstream airflow chamber surrounding the hollow cone-shaped guiding member 28, wherein the interior space 32 of the hollow cone-shaped guiding member 28 is the downstream airflow chamber, and wherein the homogenization chamber 26 is the upstream airflow chamber.
• the main unit 40 is an aerosol-generating device comprising a cartridge-and-heating section 42 and a power-and-control section 70.
• the cartridge-and-heating section 42 and the power-and-control section 70 may be detachable or may be formed as an integral main unit 40.
• the cartridge-and-heating section 42 comprises a liquid storage portion 44 filled with a liquid aerosol-forming substrate.
• the liquid storage portion 44 coaxially surrounds a tubular cavity 46 with an open proximal end 48.
• the inner diameter of the tubular cavity 46 is larger than the outer diameter of the tubular element 18 of the mouthpiece 10.
• the cartridge-and-heating section 42 comprises an atomizer configured as a heating element for heating an aerosol-forming substrate.
• the heating element comprises a ceramic heater main body 50 in connection to an electrical resistance 52 and electrical contacts 54.
• the ceramic heater main body 50 is a porous ceramic component that is in fluid communication with the liquid aerosol-forming substrate stored in the liquid storage portion 44.
• An aerosolization zone 56 is provided in a bowl-shaped cavity which is surrounded by the ceramic heater main body 50. Further provided are overmolded sealings 58, 60 for mounting the heating element in a leak-tight manner.
• the power-and-control section 70 comprises a controller 72 and a battery 74.
• the controller 72 is in electrical connection to both the contacts 54 of the heating element and the battery 74.
• Ambient air 62 enters the air inlets 14 into a first portion of the airflow path formed between walls 64 of the mouthpiece 10 and walls 66 of the cartridge-and-heating section 42.
• the air 62 further travels along a second portion of the airflow path formed between walls 18, 20 of the mouthpiece 10 and walls of the liquid storage portion 44 towards the aerosolization zone 56.
• the drawn air is mixed at the aerosolization zone 56 with the atomized aerosol-forming substrate such that an aerosol 68 is formed.
• the aerosol 68 is transported through tube inlet opening 22 into the hollow tubular element 18 with its conical end portion 20.
• the aerosol 68 further travels into the annular homogenization chamber 26.
• the annular homogenization chamber 26 provides for a turbulent airflow creating good conditions for homogenization of the aerosol 68.
• the bowl-shaped wall element 12 may additionally increase turbulence and homogenization within the annular homogenization chamber 26.
• the mixture 68 enters apertures 30 into interior space 32 of the cone-shaped guiding member 28 to finally exit the mouthpiece 10 via air outlet 34 to be inhaled by a user.
• the apertures 30 are asymmetrically, or irregularly, disposed to additionally increase turbulence and homogenization within interior space 32.
• the bowl shape of the bowl-shaped wall element 12 may assist in guiding condensed droplets 80 which have been formed within the homogenization chamber 26 back towards the heating element and the aerosolization zone 56, where the droplets may be heated to vaporize. This effect may be additionally enhanced when the surface of the bowlshaped wall element 12 comprises a hydrophobic material.
