Definitions

  • the present invention relates to an electronic smoking device for generating an inhalable aerosol, wherein the electronic smoking device comprises a mouth piece and a body section, the body section comprising a substance cartridge with an aerosolizable substance, a heating section, and a hull, wherein the heating section is arranged in between the mouth piece and the substance cartridge, and wherein the heating section is heatable to aerosolise the aerosolizable substance.
  • Such electronic smoking devices are known in the tobacco industry, wherein most of them contain a liquid inside the substance cartridge which is soaked up by a wick and transported to the heating section. The liquid then usually gets into contact with a heating element and is thereby vapoured to be inhaled through a mouth piece by a consumer. Due to fact that the heating element in such electronic smoking device usually does not heat the wick evenly, some parts are heated more than others. This leads to problems with an optimal vaporisation of the liquid, because some of the liquid will be heated too much and some will not be heated sufficiently. Furthermore some of the liquid might not be heated at all and thereby remain in the wick for various heating periods. This could result in a taste for the consumer which is not fresh, or does not correspond to the intended taste of the vaporised liquid.
  • the heating section comprises a porous material and a heating element to heat the porous material, wherein the porous material also comprises a cavity which creates a fluid flow path from the substance cartridge to the mouth piece.
  • the heating element is arranged in a way that it at least partially contacts the porous material to distribute heat from the hating element into the porous material.
  • the porous material distributes the heat evenly to ensure that the same heating temperature is maintained everywhere.
  • the heating section of the electronic smoking device is arranged in between the mouth piece and the substance cartridge of the device.
  • the heating section is preferably not geometrically arranged in between the substance cartridge and the mouth piece, but in a way, that the substance from the substance cartridge preferably has to transit the heating section to enter the mouthpiece.
  • the porous material in the heating section comprises a round, angular, cylindrical, polygonal or other geometrical shape.
  • the cavity is always arranged in the centre of the porous material.
  • the porous material comprises the shape of a tube, wherein the heating element is arranged outside the tube, and wherein the fluid flow path is arranged inside of the tube.
  • the tube is a linear tube, whereby other forms are also possible.
  • the inside of the tube is the cavity of the porous material, wherein the fluid flow path thereby flows through the tube.
  • the cavity inside the porous material comprises an angular, cylindrical, or other geometrical shape.
  • the fluid flow path is dependent on the shape of the cavity and thereby can also be non-linear.
  • the heating element being arranged outside the tube, the substance from the substance cartridge preferably does not directly get into direct contact with the heating element. It is conceivable that the heating element and the substance are arranged on opposite sides of the porous material. Thereby the heating element preferably heats the porous material, wherein the porous material transfers the heat to the substance. This preferably allows an indirect heating of the substance, and thereby an even heat distribution from the heating element to the substance.
  • the heating element is only partially arranged at the outside of the porous material, wherein an at least partial inclusion of the heating element inside the porous material would lead to a better heat dissipation from the heating element to the porous material.
  • the electronic smoking device further comprises a flow sensor to detect a fluid flow inside the device.
  • such sensor can be a flow-meter which preferably measures a fluid flow inside the electronic smoking device.
  • a sensor controls the heating element inside the device to generate a sufficient amount of heat according to a fluid flow inside the device.
  • control of the device occurs regarding and/or corresponding to the flow of the substance which is applied into the cavity.
  • the heating might also be controlled according to the flow through the mouth piece of the device.
  • aerosolizable substance is releasable from the substance cartridge into the cavity of the porous material.
  • the substance is a liquid, wherein releasing thereby preferably means spraying of the liquid from the substance cartridge into the cavity of the porous material.
  • the substance can also be a powder or different solid material which is preferably brought into the cavity by spraying and/or another suitable transport mechanism.
  • the porous material is heated before the substance is released into the cavity. Preferably by releasing the substance into the cavity, it gets into contact with the previously heated porous material. It is conceivable that thereby the substance evaporates and produces vapour which then preferably continues to flow along the flow path.
  • the substance can also be sprayed into the cavity before the porous material is heated.
  • the electronic smoking device further comprises an atomizer which is attached to the substance cartridge, wherein the aerosolizable substance is releasable from the substance cartridge through the atomizer and thereby atomisable by the atomizer into the cavity of the porous material.
  • the atomizer sprays the substance directly onto the porous material instead of spraying the substance into the cavity, which would lead to a better heat exchange from the porous material to the substance.
  • the atomizer distributes the substance evenly inside the cavity and preferably onto the porous material which surrounds the cavity which would lead to an even heating of the substance without temperature gradients. This ensures a constant taste experience.
  • the atomized substances mixes with air inside the cavity and thereby forms an aerosol which is heatable by porous material.
  • the electronic smoking device further comprises a pressure generating mechanism by which the aerosolizable substance is displaceable from the substance cartridge into the cavity.
  • the pressure generating mechanism pressurizes the substance cartridge to release the substance into the cavity.
  • the pressure generating mechanism is preferably arranged inside the device in a way to be able to pressurize the substance cartridge.
  • the substance cartridge is thereby constantly under pressure and closed towards the heating section with a valve.
  • the valve is preferably arranged in between the substance cartridge and the atomizer, wherein upon opening of the valve substance is pushed through the atomizer and is atomized into the cavity. It is conceivable that by refilling of the substance cartridge the cartridge is also pressurized once, wherein this makes an additional pressurizing mechanism inside the electronic smoking device superfluous.
  • the pressure generating mechanism is also arranged in between the substance cartridge and the atomizer, wherein the substance cartridge would then preferably not be pressurized. It is conceivable that the pressure generating mechanism receives substance from the substance cartridge and pressurizes it to push it through the atomizer into the cavity. This would make the assembly of the substance cartridge easier to manufacture, because it has not to be designed pressure tight.
  • the pressure generating mechanism is a pump and/or microelectromechanical system (MEMS) which functions upon an interaction of a consumer with the device.
  • MEMS microelectromechanical system
  • the pump can be an electrical and/or mechanical pump which could then be driven by the consumer.
  • An interaction of a consumer with the electronic smoking device preferably triggers the heating of the porous material as well as the pressure rise by the pressure generating mechanism. This would make two individual interfaces superfluous. Also the parameters of heating and substance injection into the cavity could be regulated depending on each other.
  • the consumer himself generates the pressure upon a mechanical interaction with the device.
  • the consumer could build pressure inside the substance cartridge upon pressing and thereby deforming of a deformable pouch.
  • the pouch is the substance cartridge itself and releases substance into the cavity due to a consumer applying force to it.
  • the pressure generation can also occur from a mechanical pump. Pressure building due to a mechanical force interaction from a consumer would make a MEMS and/or electrical pump superfluous and thereby save electrical power.
  • the electronic smoking device further comprises an activation sensor which is arranged to detect a consumer interaction with the device.
  • the senor detects any interaction of a consumer with the device and controls the device according to the detected interaction.
  • the sensor can be a capacitive Sensor, an optical sensor, a pressure sensor and/or a haptic interface.
  • the interaction of a consumer is preferably a haptic interaction such as touching the device, moving the device, sucking on the mouth piece and/or pressing a button.
  • the device recognizes an interaction of a consumer either automatically and/or mechanically whereafter at least one parameter inside the device is controlled.
  • This parameter could be the heating power, the substance flow rate into the cavity, the pressure generating, the mixing ratio of vapour and fresh air and other parameters of an electronic cigarette that can be regulated.
  • At least one of the controllable parameters of the electronic smoking device is controlled according to at least one sensor parameter.
  • one controllable parameter can also be dependent on multiple sensor outputs.
  • the releasing of aerosolizable substance from the substance cartridge into the heating section is based on signals from the sensor.
  • the parameters after which an aerosolizable substance is released into the heating section might be the releasing pressure, the amount, the particle size of the released substance and the direction in which the substance is released.
  • the releasing of substance into the heating section is regulated in such way that the vapour which is inhaled from a consumer through the mouth piece has constant characteristic in terms of temperature density and/or ingredients. It is conceivable that the regulation can be influenced by the consumer to meet his needs. Thereby the consumer is preferably able to manually set at least one of the regulation parameters of the device.
  • the porous material is a high temperature resistant material, which preferably comprises metal and/or ceramic materials.
  • the material preferably has a high thermal conductivity to better distribute the heat from the heating element. It is conceivable that the material also has a low heat capacity so that the heating of the porous material occurs without delay.
  • the material should also be at least partially permeable to a fluid flow to allow the fluid to flow through the material.
  • the fluid is air from outside of the device.
  • the porous material and especially the porosity of it and the aerosolizable substance are preferably matched to each other in such a way that clogging of the porous material by the substance or its residues is not possible.
  • the material is a sintered material comprising at least one metallic or one at least one ceramic component. It is conceivable that also a combination of various metallic components is possible, as well as a combination of various ceramic components.
  • the material preferably comprises at least one metal and at least one ceramic compound. It is conceivable that also other high temperature compounds can be used.
  • the porous material is heatable by the heating element to a temperature of 200 °C to 350 °C, preferably to a temperature of 200 °C to 290 °C.
  • the heating element is therefore preferably in direct contact with the porous material. It is conceivable that the heating temperature can be adjusted to fit a vaporizing temperature from the substance temperature. This would be an advantage when using an aerosolizable substance which varies in taste according to different heating temperatures.
  • the heating temperature can preferably be adjusted either continuously or in steps.
  • either the heating power itself or the resulting temperature at which the substance is vaporised can be adjusted.
  • a maximum heat output of 50W can be set.
  • the aerosolizable substance is aerosolizable by contact with the heated porous material, wherein an aerosol is releaseable from within the porous material into the mouth piece along the fluid flow path.
  • the aerosolizable substance is sprayed from the substance cartridge and through the atomizing unit directly onto the porous material which is preferably preheated and thereby vaporizes the aerosolizable substance.
  • the aerosolizable substance is finely atomized by the atomizing unit within the cavity and thus only a part of the aerosolizable substance has contact with the porous material.
  • the temperature in the cavity is high enough that the aerosolizable substance evaporates without touching the porous material.
  • the porous material is not heated initially and the aerosolizable substance is thus sprayed onto the cold material.
  • the porous material then absorbs the aerosolizable substance at least partially. It is conceivable that the porous material is then heated and the aerosolizable substance thus evaporates.
  • the porous material is a sintered material with a particle size of 1 - 80 micrometre and preferably 1 - 20 micrometre. It is conceivable that the individual particles can comprise different sizes, or that all particles comprise the same size. Preferably the particles can also comprise different geometrical shapes. It is conceivable that all particles can also comprise the same shape.
  • the device comprises a second fluid flow path which is arranged in the body section between the hull and porous material, wherein preferably this second flow path is in a fluid connection to the outside of the device through a hole in the hull.
  • the second flow path is divided from the first flow path by the heating element and the porous material.
  • the second flow path at least partially surrounds the porous material and thus also preferably lies parallel to the first flow path.
  • the second flow path preferably allows air from the environment of the electronic smoking device to flow into it and to surround the porous material.
  • the second flow path is preferably so large that a volume flow, which occurs when a consumer inhales, can flow through it.
  • the porous material connects the first liquid flow path and the second liquid flow path and thereby functions as a third liquid flow path. It is conceivable that thereby the air from outside of the electronic smoking device can flow through the second flow path into the device and afterwards through the third flow path into the first flow path.
  • the air from the outside of the device thereby passes through the porous material and mixes with the vapour from the aerosolizable substance from within the porous material. It is conceivable that this mixture is afterwards inhaled by the consumer of the device. It is conceivable that air which flows through the porous material is thereby filtered. Also the air is preferably preheated and also preferably cools the hull of the device by flowing past it and touching it.
  • the electronic smoking device can be disassembled into its individual parts and also be reassembled.
  • each part can be separated from the other parts, replaced and then the electronic smoking device can be reassembled.
  • the object of the invention is also reached by a method for creating an inhalable aerosol with an electronic smoking device, wherein the method comprises the following steps: first the porous material is heated by the heating element, then the aerosolizable substance is released from the substance cartridge into the cavity of the heated porous material and thereby aerosolised, afterwards, by pulling of a consumer at the mouth piece, air from outside of the device flows along the second and third flow path and mixes with the aerosolized substance inside the cavity, the resulting inhalable aerosol is then released from the cavity along the first flow path into the mouth piece.
