By a general overview, FIG. 1 shows a schematic diagram of a vaporization module 1 for a conventional electronic cigarette. The vaporization module comprises a core 3, which may be solid or flexible, saturated in e-liquid, in which a heating coil 5 is wound. Therefore, this component is generally referred to as a core and coil heater. In use, a current is passed through the coil 5, thereby heating the coil. This heat is transferred to the e-liquid in the core 3, thereby causing it to evaporate.

Smoking replacement devices such as e-cigarettes can be refillable to replace the consumed e-liquid. An example of the heating of an electronic cigarette 10 called a transparent atomizer, an e-liquid reservoir, and a cigarette holder area is illustrated in FIG. 2. The cigarette holder 12 may be coupled to a transparent can 14 serving as a reservoir for e-liquid. The heating arrangement comprises a core 16 which sucks the e-liquid to the heating element 20. The heating element 20 is powered by a battery coupled via an electrical connection 18. The e-liquid sucked into the heating element 20 is evaporated and forms an aerosol smoke, which can be sucked into the user's mouth by the user sucking air through the cigarette holder 12. The airflow is usually introduced via a small inlet in or near the electrical connection 18 and via a central flow path for airflow over or in close proximity to the heating element, so that the evaporated smoke oil can be entrained in the airflow and drawn into the Inside the cigarette holder 12. In general, the vapor condenses on a cooler air stream to form an aerosol smoke of the smoke oil condensate particles. Smoke oil can be scented. If the user wishes to change the aroma, he must change the e-liquid in his device. This requires emptying the can containing the e-liquid and replacing it with the e-liquid of the desired aroma. Depending on the situation, the user can use different devices or interchangeable tanks with the desired flavor e-liquid.

Scent is experienced by the user via taste and / or olfactory receptors located in his mouth and nasal cavity. The inventors have recognized that fragrance aerosols can penetrate into the mouth and nasal cavity to deliver fragrance components to users without penetrating further. However, physiologically active substances such as pharmaceutical compounds and nicotine can be delivered more efficiently through the lung system, in particular, through deep lung penetration.

Turning now to FIG. 3A, a schematic diagram of a cigarette holder unit 30 that can be used to deliver fragrance separately from an active ingredient such as nicotine using an evaporation device is shown. The cigarette holder 30 includes an open hollow cylindrical section 32 configured to receive a cigarette holder or "drip nozzle" 12 (such as a transparent atomizer as illustrated in FIG. 2) of the evaporation unit 34 and provide a fluid path. The second open-ended hollow cylindrical section 36 is configured to receive a "fragrance" element 38 and provide a fluid path. The scent element 38 is a base that supports the aerosol precursors of scent components that are typically in the form of a liquid such as the "blueberry" scent (such as the trade name FQ CO36 E-FLAVOUR BLUEBERRY) supplied by Hertz Flavors GmbH & CO. KG of Reinbek, Germany material. The fragrance element 38 includes a substrate to support the fragrance component, and through the substrate, air can be sucked from the "B" side to the "A" side. The air flow through the fragrance element 38 forms and aerosols of the fragrance components are entrained in the air flow to be carried to side A.

The user will place the cigarette holder 30 into his mouth, with the side B protruding from his mouth and sucking air from the B side to the A side so that the airflow passes from the B side through the fragrance element 38 and then inhales the fragrance aerosol to User's mouth. The user can activate the evaporation device 34 to generate aerosol smoke from the smoke oil precursor in the evaporation device by drawing air on the A side of the cigarette holder 30. By activating the evaporation device 34 when the air is sucked through the cigarette holder 30, the user will take in the aerosol from the evaporation device containing the active ingredient, and the fragrance aerosol from the fragrance element 38.

FIG. 3B schematically illustrates the cigarette holder 30 viewed from the side A. FIG. Although the display evaporation device 34 is spaced from the inner wall of the hollow cylinder 32, it is intended to improve the clarity of the disclosure and to clearly illustrate the individual components. In practice, the evaporation device will be engaged with the cigarette holder 30, usually by sliding friction fit. The same applies to the fragrance element 38 and the hollow cylinder 36.

The aerosol generated in the evaporation device 34 is formed by heating of the vapor precursor liquid, so that it usually has a thickness of less than or equal to 10 microns, preferably less than 8 microns, more preferably less than 5 microns, and more preferably 1 micron mass median aerodynamic particle size. Aerosols of this size tend to penetrate into the lung system of human users. The smaller the aerosol, the more likely it is to penetrate deeper into the lung system, and the more effectively the active component is transmitted to the user's blood system. This deep lung penetration is something that is desirable for the active component but not necessary for the fragrance component. Fragrance components can enter the user's mouth and / or nasal cavity to activate taste and / or olfactory receptors and not penetrate the lung system.

The fragrance component is configured such that it typically forms one of 15 μm or greater, more than 30 μm in detail, more than 50 μm in more detail, still more than 60 μm, and even more specifically more than 70 μm Mass median aerodynamic particle size. Without being bound by any theory, this size of the aerosol can be formed by aspirating liquid droplets (by the air flow on the substrate) from the substrate at the ambient temperature (eg, room temperature) of the user's environment. The size of the aerosol formed without heating is usually smaller than the size of the aerosol formed by condensation of the vapor. The size of aerosols that are formed without heating (such as suction of air through a substrate that supports the liquid) can be affected by the ambient temperature, viscosity, and or density of the liquid. However, in general, and more likely, an aerosol formed without heating has a size that is considerably larger than an aerosol formed via heating. The fragrance aerosol may be formed with a maximum mass median aerodynamic particle size, the maximum mass median aerodynamic particle size being less than 300 microns, more specifically less than 200 microns, and more specifically less than 100 microns. This series of mass median aerodynamic particle sizes will be generated small enough to be trapped in the airflow caused by the user's suction of air through the fragrance element 38 and enter and extend through the mouth and / or nasal cavity to activate taste and / or olfactory receptor Aerosol.

In short, it should be understood that the median aerodynamic particle size is a statistical measurement of the size of particles / droplets in an aerosol. That is, the mass median aerodynamic particle size is quantified together to form the size of the aerosol droplets. The mass median aerodynamic particle size can be defined as 50% by mass particles / droplets in an aerosol larger than the mass median aerodynamic particle size and 50% by mass particles / droplets in an aerosol are less than the mass median aerodynamic particles Diameter. As used herein, the "aerosol size" refers to the size of the particles / droplets contained in a particular aerosol. For example, the size of particles / droplets in an aerosol can be quantified by the median aerodynamic particle size.

The size of the aerosol generated by the aerosol generator may depend on, for example, the temperature of the liquid precursor, the density of the liquid precursor, the viscosity of the liquid precursor, or a combination. The size of the aerosol generated by the aerosol generator may also depend on the specific parameters and configuration of the aerosol generating equipment described in more detail below.

The fragrance element 38 may be formed of any suitable porous material for providing a substrate. For example, it may be formed of a material commonly used as a filter for cigarettes or a substrate material for Nicorette inhalator ™ (ie, porous polypropylene or polyethylene terephthalate). The liquid fragrance component can then be dropped onto the fragrance element 38. The fragrance element 38 substrate may comprise a porous material, wherein the pores of the porous material hold, contain, carry, or possess a fragrance compound. Optionally or in addition, the porous material may include a sintered material such as BioVyon ™ (produced by Porvair Filtration Group Ltd).

In the embodiment illustrated in Figure 4, the cigarette holder 40 is shaped to fit to the mouth of a user in a conventional configuration for a cigarette holder. The tapered fluid flow channel 42 is connected to the mouth end of the cigarette holder 40 and is coupled to the cavity 44 for receiving the evaporation device through the fluid flow channel 46. The cavity 58 is configured to receive a fragrance box 50 holding a fragrance element 54. The fragrance box 50 has a cavity 52 containing an opening 53 that is sized to allow the fragrance element 54 to be inserted into the cavity 52. The cavity 52 also contains a coil spring 56. The coil spring 56 is disposed at an end of the cavity 52 opposite to the opening 53.

The fragrance element 54 is placed in the fragrance box 50 so as to rest on the coil spring 56. A piezoelectric vibration unit 60 is disposed in contact with one end of the fragrance element 54 and is powered by an electrical connection 62. The piezoelectric element 60 includes a piezoelectric crystal that can be electrically coupled to a power supplier, such as a battery, via a connection 62. The piezoelectric element 60 includes a perforated film that is vibrated by the piezoelectric crystal or formed by the piezoelectric crystal itself. The perforations in the vibrable film form droplets of the fluid fragrance component absorbed in the fragrance element 54 when the film is vibrated. For example, vibrations are typically in the range of 100 kHz to 2.0 MHz, specifically between 108 kHz and 160 kHz, and more specifically at substantially 108 kHz. These vibration frequencies can be used to form an aerosol that can be drawn by the airflow from the fragrance element 54 to the end of the cigarette holder 50 and has a liquid fragrance component of a size as set forth in the above range.

The electrical connection 62 may be coupled to the power supply via a switch operated by a user or in response to a pressure drop in the runner 42 / cavity 58 when the user draws air from the mouthpiece 40. Optionally, the electrical connection 62 may be coupled via a switch on the evaporation device (SMP), so that when the user activates the evaporation device, the piezoelectric element 60 is activated.

Another configuration for a device containing separate fragrance and nicotine aerosol delivery is illustrated in Figures 11 and 12.

For the avoidance of doubt, in the following description of Figures 11 and 12, the term "upstream" defines a position toward a point where fluid will be drawn into the aerosol outlet duct 168 when the device is in use, that is, containing gas The air of the sol is sucked into the aerosol outlet duct 168 from the atmosphere and / or from the aerosol generating unit 162. The term "downstream" defines the position from the point at which the fragrance-containing fluid exits the fragrance element 172. Based on these definitions, any fluid in the fluid channel 170 "upstream" of the fragrance element 172 does not contain any fragrance components, and any fluid in the fluid channel "downstream" of the carrier unit 172 may contain fragrance (depending on the fragrance element Does 172 contain a liquid flavor component and / or flavor compound, and the extent to which the flavor component is inhaled into the fluid as it passes over the carrier unit 172).

A cross-sectional side view of the device 150 is schematically illustrated in FIG. 11. As can be seen in FIG. 11, the fragrance element 172 includes a substrate 174 which, in one or more embodiments, is saturated with a liquid fragrance component and / or a fragrance compound. Optionally, the substrate 174 may include a porous material, wherein the pores of the porous material hold a liquid flavor component and / or flavor compound. In addition, as appropriate, the porous material may contain a sintered polymer such as BioVyon ™ (produced by Porvair Filtration Group Ltd). The porous material of the substrate 174 is configured to "wick" or "suck" the nicotine precursor material away from the end region of the substrate 14 (ie, toward the center region of the substrate 174). This prevents the liquid fragrance component from leaking from the substrate (and therefore from the carrier unit 172 when the penetrating film of the sealed fragrance element (not shown in Figures 11 to 12) is broken). Thus, the liquid fragrance component can be held within the substrate 14 until the airflow passing through it (ie, during use) causes aerosolization, and an aerosol is generated from the liquid fragrance component.

The evaporator portion 164 of the aerosol generating unit 162 includes: a reservoir 176 configured to contain vapor precursor material; an evaporation arrangement 178 configured to vaporize the vapor precursor material; and a fluid flow channel 180 It is used to deliver an aerosol formed from a vapor precursor material to a fluid flow channel 170 of an aerosol outlet pipe 168.

The vapor precursor material may be in liquid form and may be saturated with one or more of ethylene glycol, polyethylene glycol, propylene glycol, and water.

The evaporation arrangement 178 includes a chamber (not shown) for holding the vapor precursor material received from the reservoir 176 and a heating element (not shown) for heating the vapor precursor material in the chamber.

The evaporation arrangement 178 further includes a duct (not shown) in fluid communication with the chamber and configured to deliver an aerosol formed from the heated vapor precursor material in the chamber to the vapor channel 180.

The evaporation arrangement 178 further includes a control circuit (not shown) that is operated by the user or upon detecting that the air and / or aerosol is being drawn through the aerosol outlet duct 168, that is, when the user inhales or inhales .

The battery part 166 of the aerosol generating system 162 includes a battery 182 and a coupling member 184 for mechanically and electrically coupling the battery part 166 to the evaporator part 164. When the battery portion 166 and the evaporator portion 164 are coupled as shown in FIG. 11, the battery 182 is electrically coupled to the evaporation arrangement 178 to power it.

In response to activating the control circuit of the evaporation arrangement 178, the heating element heats the vapor precursor material in the chamber of the evaporation arrangement 178. The vapor formed as a result of the heating process forms an aerosol of liquid condensate, which passes through the pipe to the fluid path channel 180 of the evaporator portion 164. This aerosol containing fluid then enters the upstream region of the aerosol fluid path 170 of the aerosol outlet duct 168 via the fragrance element 172, where the fragrance from the substrate 174 is entrained in the aerosol flow and then forwards through the aerosol fluid path Area 170 downstream for delivery to the user.

This process is illustrated in Figure 12, where arrow 186 schematically represents the flow of the aerosol fluid stream, which passes from the aerosol channel of the evaporator section to the upstream area of the aerosol fluid path 170 of the aerosol outlet pipe 168, passing through the fragrance Element 172, and then passes through a region downstream of the aerosol fluid path 170 for delivery to a user.

Figure 12 also schematically illustrates the fragrance and / or fragrance compound 188 contained in the substrate 174, and the fragrance that enters the aerosol fluid stream 186 from the substrate 174 (ie, becomes entrained in the aerosol stream 186). And / or fragrance compounds. The fragrance and / or fragrance compounds in the aerosol stream 186 are represented by reference numeral 190.

FIG. 5 is a schematic diagram of another embodiment, in which the fragrance element 70 provides a substrate for a liquid fragrance component, wherein the substrate is structurally layered and has a series of laminates 72. The airflow drawn from the B side passes through the layered structure, and an aerosol of a liquid fragrance component is generated. The aerosol becomes entrained in the airflow and is carried to the A side to the user's mouth. The scent element 70 may be placed on the cigarette holder 30 (such as illustrated in Figures 3A and 3B and described with reference to Figures 3A and 3B) or the cigarette holder 40 (as illustrated in Figure 4 and described with reference to Figure 4 Description).

The scent element 70 may also be disposed in the device 150 instead of the scent element 172 illustrated in FIGS. 11 and 12.

FIG. 6 is a schematic view of still another embodiment, in which the fragrance element 70 is formed of a hollow tubular section having an open capillary filament 76 extending from the inner wall 78 of the tube. The capillary element may be filled with a liquid fragrance component. The air flow through the tube (illustrated from a non-limiting example as end B to end A) creates a pressure drop over the free end of one or more of the capillary elements 76, so that droplets of the liquid scent component exit the capillary The beginning of the element is sucked and entrained in the air flow from B to A. Optionally, the wall 78 may include a reservoir of one of the liquid fragrance components, and the capillary filaments 76 are inserted into or extended from the reservoir to draw the liquid fragrance component from the reservoir to the capillary filaments. Freedom of 76 begins. The reservoir may be a suitable matrix formed of a porous material, formed integrally with or separate from the wall, and inserted into the tube during assembly of the fragrance element 74.

Capillary filaments have a diameter to form aerosol-sized droplets in the ranges set forth above. In general, the diameter-opening pores around the desired median diameter of the aerosol to be generated generate aerosols of this median diameter. The precise size of the particles / droplets contained in the aerosol will depend in particular on the surface tension and temperature of the liquid fragrance component and the pressure exerted on it. In the described embodiment, the capillary filaments or at least this start is a hydrophobic material in order to produce the release of droplets of liquid.

In the embodiment schematically illustrated in FIG. 7, the individual aerosol generators are placed in the apparatus 80 in a side-by-side relationship. The aroma aerosol generator 82 and the active ingredient aerosol generator 84 are described in a side-by-side relationship. Air can be drawn into the fragrance aerosol generator 82 from the outside air holes 86 and into the fragrance aerosol generator 82 through the air holes 95. In a similar manner, air is drawn into the active ingredient aerosol generator 84 through the external air holes 88 and into the active ingredient aerosol generator through the air holes 97. The aerosol-laden fluid exits the fragrance aerosol generator 82 and the active component aerosol generator 84 through the exit apertures 96 and 98, respectively. The outlet apertures 96 and 98 provide fluid communication to the mouthpiece 90 through the apertures 92 and 94. The cigarette holder 90 creates an inflatable chamber in which the aerosol can be mixed before being inhaled by the user. The active ingredient aerosol generator 84 includes a vapor generator arrangement, such as used in conventional evaporation devices to supply electricity with heaters and batteries that supply electricity. For the convenience and clarity of disclosure, the details of the heater and the battery pack are not illustrated in the figure.

Another embodiment according to the present invention is schematically illustrated in FIG. 8, which shows the apparatus 100 in which the respective aerosol generators 102/104 and 106 are arranged in a concentric configuration. In the described embodiment, the fragrance aerosol generators 102/104 are arranged in a concentric arrangement around the active ingredient aerosol generator 106. The respective reference numerals 102 and 104 are used to illustrate the respective parts of the scented aerosol generator on either side of the active ingredient aerosol generator 106 when the device 100 is shown in cross section. The device has a cigarette holder 108 disposed at one end. An aperture 110 provides fluid communication from the output ends of the fragrance and aerosol generators 102/104 and 106 to the cigarette holder 108, respectively. Air can be drawn into the aerosol generator through the external gas inlets 112, 114, and 116. As illustrated, the perforated duct 118 allows air drawn through the external air inlets 112, 114, and 116 to be inhaled into any one of the aerosol generators to ventilate the aerosol generators at 119 and 120. In an alternative embodiment, the ducts 118 are not perforated and keep separate airflows apart. Similarly, for the embodiment illustrated in Figure 7, the active ingredient aerosol generator 106 comprises one generator as commonly found in conventional evaporation equipment.

In an alternative embodiment, the active ingredient aerosol generator 106 may be arranged in a circumferential arrangement around the fragrance aerosol generator 102/104.

FIG. 9 illustrates a further embodiment according to the present invention, wherein the device 130 includes a corresponding active component aerosol generator 132 and one of the scented aerosol generators 134 arranged in a line. The active ingredient aerosol generator 132 is in fluid communication with the fragrance aerosol generator 134 via a fluid conduit 135. The fluid path through the active component aerosol generator 132 and the fragrance aerosol generator 134 is coupled to the aperture 114 through the fluid pipe 136 and into the cigarette holder 138. Air is drawn into the active ingredient aerosol generator 132 from the external air inlets 142, 144, and 146 through the perforations 148. Similarly, for the embodiment illustrated in Figure 7, the active ingredient aerosol generator 132 comprises one generator as commonly found in conventional evaporation equipment.

In the embodiment schematically illustrated in FIG. 10, a similar arrangement illustrated in FIG. 9 is disclosed. Similar parts will be referred to with similar numbers, but the active component aerosol generator and the scented aerosol generator are reversed. . Therefore, upstream of the active ingredient aerosol generator 132 'is a fragrance aerosol generator 134'.

For example, the scented aerosol generator of any of the embodiments disclosed in FIGS. 7 to 10 may be used as disclosed in FIGS. 11 to 12 as shown in FIGS. 3 to 6. Aroma component configuration. However, any suitable aerosol-generating mechanism may be used to generate an aerosol in the range defined above for a fragrance aerosol.

For clarity, the active ingredient aerosol generators in the foregoing and subsequent embodiments are configured to generate aerosols sized for lung penetration (more specifically, deep lung penetration), and generally produce The size is an active ingredient aerosol having a mass median particle size of less than or equal to 10 microns, preferably less than 8 microns, more preferably less than 5 microns, and even more preferably less than 1 micron. It is the case that aerosols formed from vapor condensates (ie, aerosol fumes such as those found in typical e-cigarettes or evaporation equipment) may fall within a defined size range, or at least a large proportion of them Within the defined size range. For example, it is reasonable to expect that 50% of the active ingredient aerosol will fall within the defined size range. Preferably, the larger percentage falls within a defined size range, for example, 75% or even higher. However, it may be acceptable to have a lower percentage within the defined size range, such as as low as 25% of the active ingredient aerosol.

Fragrance component aerosols can be produced in many ways, some of which have been described above. The generation of aerosols (sometimes referred to as "atomization") has been described in technical and scientific literature, and these techniques can be applied, adapted, or modified for the scented aerosol generators and components according to the present invention using embodiments . A review of aerosolization and aerosol-generating technologies and methods will now be provided. For the avoidance of doubt, references to droplets or particles are also references to aerosols and may include droplets such as vapor condensates and / or solid particles.

Aerosols are initially formed by atomization or condensation of vapor. Atomization is the process of dividing large pieces of fluid into droplets or particles. The process of dividing large pieces of fluid into sprays or aerosols carrying particles is usually accomplished using so-called atomizers. Common examples of atomizers include shower heads, perfume sprays, and hair or deodorant sprays. FIG. 13 is a schematic diagram of a typical atomizer and a range of particle sizes generated therefrom.

Aerosols are a collection of moving particles that are the result of atomization; for most non-naturally occurring atomization applications, aerosols move particles in a controlled manner and direction. Generally, for most everyday applications, aerosols contain a range of particle sizes, depending on the various inherent and environmental parameters discussed below.

Due to the surface tension of the fluid, the droplets or particles of the fluid have a more or less spherical shape. This surface tension makes the flakes or ribbons of the fluid unstable; that is, to separate into particles and / or atomize. As a general case, as the temperature of a fluid increases, its surface tension tends to decrease correspondingly.

Various properties and factors affect the size of the droplets or particles, and the ease with which the fluid can be atomized after being ejected from a pore; these include surface tension, viscosity, and density.

Surface tension: Surface tension tends to stabilize the fluid, preventing it from breaking into droplets of particles. Fluids with higher surface tension tend to produce droplets or particles having a larger average droplet size or diameter after atomization.

Viscosity: The viscosity of a fluid has a small effect on the size or diameter of droplets or particles formed as surface tension during atomization. The viscosity of the fluid resists agitation, preventing large pieces of fluid from separating into droplets or particles. Therefore, fluids with higher viscosity tend to produce droplets or particles having a larger average droplet size or diameter after atomization. Figure 14 graphically illustrates the relationship between viscosity and droplet size when fogging occurs and aerosols form.

Density: Density makes fluids resist acceleration. Therefore, again, fluids with higher density tend to produce droplets or particles with a larger average droplet size or diameter after atomization.
Atomization process

The process of atomization (that is, the process that can lead to the formation of an aerosol) can take many different forms.
Pressure atomization

Also known as airless, air-assisted airless, hydrostatic and hydraulic atomization, the pressure atomization process involves forcing the fluid through a small nozzle or orifice under high pressure, so that the fluid is ejected at high speed as a solid flow or sheet. The friction between the fluid and the air disrupts the flow, causing it to break up into fragments at first, and eventually into droplets. FIG. 15 schematically illustrates a high-speed water spray 200 divided into one of the droplets 202 in an airless atomizing system. In this system, the high-speed water spray 200 is discharged from a suitable pore.

Many factors affect the flow and droplet size, including the diameter of the orifice, the external atmosphere (temperature and pressure), and the relative velocity of the fluid and air. As a general case, the larger the diameter of the nozzle orifice, the larger the average droplet diameter in the spray.

The external atmosphere resists spraying and tends to shatter fluid flow; this resistance tends to partially overcome the surface tension, viscosity, and density of the fluid.

The relative velocity between fluid and air has the greatest effect on the average diameter of the droplets in the aerosol. Since the velocity of the fluid sprayed through the nozzle orifice depends on the pressure, as the fluid pressure in the nozzle increases, the average diameter of the droplets decreases accordingly. Conversely, as the fluid pressure decreases, the velocity is lower and the average diameter of the droplets increases. FIG. 16 schematically illustrates an airless atomization process in which pressurized fluid is sprayed from a circular orifice into the atmosphere.
Air atomization

In air atomization, the fluid is ejected from the nozzle orifice 210 at a relatively low speed and low pressure, and is surrounded by a high-speed air stream 212. Friction between fluid and air accelerates and disrupts fluid flow, and causes atomization. Because the main energy source for atomization is air pressure, the fluid flow rate can be adjusted independently of the energy source. Therefore, air atomization has been used as the main technique for atomization in medical inhalation and device technology. Fig. 17 schematically illustrates this arrangement, in which a fluid flow passes through an orifice, wherein as the fluid flow appears, a high velocity air flow surrounds the fluid flow.
Centrifugal atomization

FIG. 18 schematically illustrates a centrifugal or rotary atomization system 220 (also referred to as rotary atomization). The nozzle 222 introduces fluid at the center of the rotating disk 224 or cone. Centrifugal force carries fluid to the edge of the disc or cone. As it is ejected from the edge of the pan or cone, the liquid forms a ribbon 226 or sheet that divides the bulk liquid into droplets or particles.

At the same rotational speed, droplets form closer to the edge of the disk at slower fluid flow rates than at higher flow rates. The liquid is ejected from the edge of the disc and moves radially away from the disc in all directions (ie, 360 °). Therefore, these droplets are entrained in a directional airflow or shaped clock to cause the aerosol to travel in the axial direction.

The flow velocity and disc velocity of the fluid introduced onto the rotating disc or cone can be controlled independently of each other.
Supersonic atomization

Ultrasonic atomization relies on an electromechanical device that vibrates at high frequencies. High-frequency oscillations separate fluids that cross or pass through a vibrating surface into droplets.

There are many types of ultrasonic sprayers including ultrasonic atomizers and vibrating mesh atomizers.
Ultrasonic atomizer

A thin liquid layer is deposited on the surface of the resonator (typically, the resonance surface connected to the piezoelectric element), and then the resonator is mechanically vibrated at a high frequency in the direction A. When the vibration amplitude exceeds a threshold value, the vibration causes a pattern of resident surface tension waves with a standing wave wavelength λ. After the vibration amplitude is increased above the threshold, the liquid ribbon breaks and droplets are ejected from the top / peak of the surface tension wave. Fig. 19 schematically illustrates the principle of operation of the ultrasonic atomization system.

As schematically illustrated in Figure 20, a dish-shaped ceramic piezoelectric transducer or resonator converts electrical energy into mechanical energy. These transducers receive electrical inputs in the form of high-frequency signals from a generator and convert them into vibrational motion at the same frequency. The two titanium cylinders zoom in and increase the vibration amplitude of the atomized surface.

The nozzle is designed so that the excitation of the piezoelectric crystal contained in the transducer generates a standing wave along the length of the nozzle. The ultrasonic energy from a crystal located in the large diameter of the nozzle body undergoes a step transition and amplification as a standing wave as it passes the length of the nozzle.

Because the wavelength depends on the operating frequency, the nozzle size is controlled by the frequency. In general, high-frequency nozzles are smaller, produce smaller droplets, and therefore have a smaller maximum flow capacity than nozzles operating at lower frequencies.

The nozzle is preferably made of titanium due to its good acoustic properties, high tensile strength and excellent corrosion resistance. The liquid is introduced onto the atomized surface via a feed tube running along the length of the nozzle, which feed tube absorbs some of the vibrational energy and generates wave motion in the liquid on the surface. For liquid atomization, the vibration amplitude of the atomized surface must be carefully controlled. Below the so-called critical amplitude, the energy is not enough to produce atomized droplets, and if the amplitude is too high, the liquid is torn apart and a "bulk" fluid is ejected (a condition called "cavitation").

Since supersonic atomization relies only on the liquid being introduced onto the atomized surface, the rate at which the liquid is atomized depends only on the rate at which it is delivered to the surface.

Ultrasonic atomizers are particularly suitable for low pressure / low speed applications and provide a highly controlled aerosol spray. Therefore, since the atomization process does not depend on fluid pressure, the volume of the atomized liquid can be controlled by the liquid delivery system and can range from more than a few microliters. In addition, by entraining the low-speed aerosol spray in the auxiliary airflow, the aerosol spray can be precisely controlled and shaped to produce a spray pattern as small as approximately 1.8 mm wide.

In addition, the droplets produced by ultrasonic vibrations have a relatively narrow average diameter distribution. Depending on the operating frequency of the nozzle, the median droplet size ranges from 18 microns to 68 microns. For example, Sono-tek claims that its ultrasonic spray nozzles can produce a droplet diameter of about 40 microns, with 99.9% of the droplets having a diameter falling in the range of 5 microns to 200 microns.
Static web atomization

The static mesh atomizer applies force to the liquid to force it through the static mesh, as shown in FIG. 21. Ultrasonic transducers are used to generate vibrations in the liquid and push the droplets through a static mesh.
Vibration net atomization

A vibrating web atomizer uses web deformation or vibration to push liquid through the web, as shown schematically in Figure 22. Typically, a ring-shaped piezoelectric element in contact with the mesh is used to generate vibrations around the mesh. The hole in the net has a conical structure in which the largest cross section of the cone most closely contacts the liquid reservoir. The face of the net deforms towards the liquid reservoir, so the liquid is drawn into the hole and the hole is filled with liquid. The deformation of the face on the other side of the net ejects droplets through the holes.

The size of the droplets and aerosols produced depends on the size of the holes in the net and the physicochemical properties of the liquid. However, one of the disadvantages of the vibrating net device is the possibility of plugging holes in the net, especially in the case of solutions that are too viscous to pass through the net.

Figures 23 and 24 each show a replacement smoking system according to one of the inventions. In Figure 23, the components replacing the smoking system are separated from each other. In Figure 24, the components replacing the smoking system are interconnected.

As shown in FIGS. 23 and 24, the replacement smoking system includes a replacement smoking device 300. Also shown are two types of consumables 301, 302-an atomizing cylinder 301 and a fragrance box 302. The atomizing cylinder 301 is configured to directly engage the replacement smoking device 300. The atomizing cylinder 301 may be engaged with the replacement smoking device 300 via, for example, a push-fit engagement, a screw thread engagement, or a bayonet fit. The atomizer can also be called a "box".

The fragrance box 302 is configured to interface with the atomizing cylinder 301, and thus to replace the smoking device 300. The fragrance box 302 may be engaged with the atomizing cylinder 301 via, for example, a push-fit engagement, a screw thread engagement, or a bayonet fit. FIG. 24 illustrates an atomizing tube 301 coupled with the smoking device 300 and a fragrance box 302 coupled with the atomizing tube 301. It will be understood that in the systems of FIGS. 22 and 23, the atomizing cylinder 301 and the fragrance box 302 are distinct elements. Both the atomizing cylinder 301 and / or the fragrance box may be consumables.

A "consumable" component may mean that the component is intended to be used once until it is exhausted, and the subsequent piece is discarded as waste or returned to the manufacturer for reprocessing.

Instead of each of the smoking device 300, the atomizing cylinder 301, and the fragrance box 302, it is a substantially elongated element. Each has a longitudinal axis parallel to the longest axis of the respective element.

As will be understood from the following description, the atomizing tube 301 and the fragrance box 302 may alternatively be combined into a single component that implements the functions of the atomizing tube 301 and the fragrance box 302. According to the present invention, this single component can also be a consumable.

25 and 26 illustrate a replacement smoking system according to one of the present invention, which includes a replacement smoking device 300 and a single consumable 303. The consumable 303 combines the functions of the atomizing tube 301 and the fragrance box 302. In Figure 25, the components replacing the smoking system are separated from each other. In Figure 26, the components replacing the smoking system are interconnected.

Instead of each of the smoking device 300 and the consumable 303, it is a substantially elongated element. Each has a longitudinal axis parallel to the longest axis of the respective element.

FIG. 27 shows a consumable 303 according to the present invention, which performs the functions of an atomizing cylinder 301 and a fragrance box 302 according to the present invention.

In Fig. 27, the display consumable 303 and a replacement smoking device 300 are joined via a push-fit engagement. Consumable 303 is a single component (eg, in Figures 25 and 26). The consumable 303 can be regarded as having two parts-an atomizing cylinder part 304 and a fragrance box part 305.

The consumables 303 include an upstream inlet 306 and a downstream outlet 307. A particular consumable may include multiple inlets and / or multiple outlets. There is an air flow channel 308 between the inlet 306 and the outlet 307. The outlet 307 is located at the mouthpiece end 309 of the consumable 303. The user smokes (or "sucks" or "smokes") on the mouthpiece end 309 of the consumable 303. When the user draws on the mouthpiece end 309, the drop in air pressure at the outlet 307 causes the airflow to the inlet 306, follows the airflow channel 308, and exits from the outlet 307. The air flow exits from the outlet 307 located at the mouthpiece end 309 and flows into the mouth of the user.

The atomizing cylinder portion 304 of the consumable 303 includes an e-liquid storage tank 310. The e-liquid storage tank 310 contains a supply of e-liquid ("vapor precursor material") corresponding to the first aerosol precursor. Extending into the e-liquid storage tank 310 is a core 311. The wick 311 is formed from a porous wicking material (for example, a polymer) that sucks e-liquid from the e-liquid storage tank 310 into a central area of the 311 outside the e-liquid storage tank 310.

A heater 312 is configured to heat a central area of the core 311. The heater 312 includes a resistive heating filament coiled around a central region of the core 311. The core 311, the heater 312, and the e-liquid storage tank 310 may correspond to an active aerosol generator (or "first aerosol generator").

When the heater 312 is activated (by passing an electric current through the heating filament), the e-liquid located in the core 311 adjacent to the heating filament is heated and evaporated to form a vapor. The vapor may condense to form a first aerosol. The first vapor / aerosol is generated in the air flow channel 308. Therefore, the first aerosol is entrained in the airflow, flows along the airflow flow channel 308 to the outlet 307, and finally exits from the mouthpiece end 309 for inhalation by the user when the user draws on the mouthpiece end 309.

In order that power can be supplied to the consumable 303 for starting the heater 312, the consumable 303 includes a pair of consumable electrical contacts 313. The consumable electrical contacts 313 are configured for electrical connection to one of a pair of corresponding power contacts 314 in place of the smoking device 300. When the consumable 303 is connected to the smoking device 300 instead, the consumable electrical contact 313 is electrically connected to the power supply contacts 314. Instead of smoking device 300, a power source (not shown), such as a battery, is included. Instead of the smoking device 300, an electric current is supplied to the consumable electric contact 313. This causes a current to flow through the heating filaments of the heater 312, and the heating filaments become hot. As described, the heating of the heating filament causes evaporation of the e-liquid in the core 311 to form a first aerosol.

As above, the consumable 303 includes a fragrance box portion 305. The fragrance box portion 305 is configured to generate a second (fragrance) aerosol for output from the outlet 307 of the mouthpiece end 309 of the consumable 303. The fragrance box portion 305 of the consumable 303 includes a porous tip 315. The porous tip 315 may correspond to a passive aerosol generator ("second aerosol generator"). The porous tip 315 is an example of a porous member.

A scented liquid storage tank 316 is fluidly connected to the porous tip 315. The porous nature of the porous tip 315 means that the fragrance fluid from the fragrance liquid storage tank 316 is sucked into the porous tip 315. As the fragrance liquid in the porous tip 315 is depleted, another fragrance liquid is sucked into the porous tip 315 from the fragrance liquid storage tank 316 via the wicking effect.

The porous tip 315 is located in an air flow passage 308 passing through the consumable 303. The porous tip 315 constricts or narrows the airflow channel 308. The airflow channel 308 may be narrowest at the porous surface 318 adjacent the porous tip 315. Shrinkage may correspond to a Venturi void 319. The contraction of the airflow channel 308 causes a decrease in the air pressure in the airflow near the porous surface 318 of the porous tip 315. The corresponding low pressure region causes a second (fragrance) aerosol to be generated from the porous surface 318 of the porous tip 315.

It should be understood that the fragrance storage tank 316 may be omitted. The porous tip 315 may serve as a storage portion of the scented liquid. For example, the porous tip 315 may be immersed in a scented liquid ("second aerosol precursor"). As the scented liquid is depleted at the porous surface 318, wicking can replace the depleted liquid from the storage portion of the porous tip 315.

The porous tip 315 is located in the air flow channel 308 of the consumable 303. In FIG. 24, an upstream portion of one of the porous tips 315 is seated in a pointed housing 317. A downstream portion of one of the porous tips 315 is exposed to an airflow via an airflow channel 308. As the air flows over the porous surface 318 of the porous tip 315, a second (fragrance) aerosol is generated from the porous tip 315. The second (fragrance) aerosol is entrained into the air stream and is finally output from the outlet 307 of the consumable 303 and therefore from the mouthpiece end 309 into the user's mouth.

Both the active aerosol generator (corresponding to the first aerosol generator) and the passive aerosol generator (corresponding to the second aerosol generator) may be located in the airflow channel 308. The passive aerosol generator may be located downstream of the active aerosol generator. In use, the airflow flowing over the porous surface 318 of the porous tip 315 may have a first aerosol entrained therein.

As above, the active aerosol generator corresponds to the first aerosol generator to generate a first aerosol from a first aerosol precursor (eg, e-liquid). The first aerosol may be sized for lung penetration, as described above. The above description of the properties of the first aerosol is applicable to the aerosol generated by the active aerosol generator. The active aerosol generator is an electric aerosol generator. That is, the active aerosol generator generates vapor / aerosol in response to the supplied power.

The passive aerosol generator corresponds to a second aerosol generator to generate a second aerosol from a second aerosol precursor (eg, a scented liquid). The second aerosol can be sized to inhibit lung penetration, as described above. The above description of the properties of the second aerosol may be applied to the aerosol generated by the passive aerosol generator. The passive aerosol generator does not need to supply electrical energy to generate a second aerosol. In a consumable including both active and passive aerosol generators, the passive aerosol generator may be configured to be electrically isolated from a power supplier that powers the active (first) aerosol generator. The passive aerosol generator is configured to generate vapor / aerosol without a supply of electricity.

As above, the second aerosol may be transportable in at least one of the following: a mammalian oral cavity and a mammalian nasal cavity, and the second aerosol may include an activity for activating at least one of the following Components: one or more taste receptors in the oral cavity and one or more olfactory receptors in the nasal cavity.

FIG. 28 shows an alternative view of the consumable 303 and an alternative smoking device 300 of FIG. 27.

As shown in FIG. 28, during the normal use of the consumable 303, one surface of the porous tip 315 is visible by the user from outside the consumable 303. More specifically, a part of the porous tip 315 is substantially located at the outlet 307 of the consumable 303, which is in turn located at the mouthpiece end 309 of the consumable 303. In other words, the outer surface of the porous tip 315 may form one outer surface of the consumable 303. For example, the outlet 307 may include a hole in the housing of the consumable 303, and the hole portion is blocked by the porous tip 315. Having a direct line of sight from the outlet 307 to the porous tip 315 means that the second (fragrance) aerosol generated at the surface of the porous tip 315 can travel directly from the porous tip 315 to the user's mouth. Therefore, the second (fragrance) aerosol is more likely to exit the consumable 303 and enter the user's mouth.

Because the second (fragrance) aerosol is generated passively (ie, without heating), the temperature of the air stream is not increased by the porous tip 315. Therefore, it is possible that the porous tip 315 (passive aerosol generator) may be located at or near the mouthpiece end 309. Conversely, an active aerosol generator may generate hotter vapors / aerosols, which may have inappropriately high temperatures for delivery to the user's mouth from an active generation location at or near the mouthpiece end 309.

When the airflow traverses the porous surface 318 of the porous tip 315, a second (fragrance) aerosol is generated. The second aerosol is generated at an aerosol generating position on the porous surface 318 of the porous tip 315. The aerosol generating position may be near the outlet 307 of the mouthpiece end 309 of the consumable 303.

For example, the distance between the aerosol generating location and the outlet 307 may be less than 4.0 cm, preferably less than 3.5 cm, more preferably less than 3.0 cm, more preferably less than 2.5 cm, more preferably less than 2.0 cm, and more preferably The ground is less than 1.5 cm, more preferably less than 1.0 cm, and more preferably less than 0.5 cm.

The distance between the aerosol generating location and the exit 307 may be greater than 3.5 cm, preferably greater than 3.0 cm, more preferably greater than 2.5 cm, more preferably greater than 2.0 cm, more preferably greater than 1.5 cm, and more preferably greater than 1.0 cm , More preferably greater than 0.5 cm.

The distance between the aerosol generating position and the outlet 307 can be selected independently of the above values. For example, the distance between the aerosol-generating location and the outlet 307 may be between 0.5 cm and 2.5 cm; or between 1.5 cm and 3.5 cm.

The distance between the aerosol generating position of the passive aerosol generator and the active aerosol generator (for example, the position of the core and the heater) may be greater than 1.0 cm, preferably greater than 1.5 cm, more preferably greater than 2.0 cm, more It is preferably greater than 2.5 cm, more preferably greater than 3.0 cm, and more preferably greater than 4.0 cm.

The distance between the aerosol generating position of the passive aerosol generator and the active aerosol generator (for example, the position of the core and the heater) may be less than 8.0 cm, preferably less than 5.0 cm, more preferably less than 4.0 cm, more Better than 2.0 cm.

The distance between the aerosol generating position of the passive aerosol generator and the active aerosol generator (for example, the position of the core and the heater) can be selected independently of the above values. For example, the distance between the aerosol generating position of the passive aerosol generator and the active aerosol generator (for example, the position of the core and the heater) may be between 2.0 cm and 8.0 cm; or between 1.5 cm and 4.0 cm.

As shown in FIG. 28, one of the housings 320 of the consumable 303 includes a nozzle 321 that surrounds the exposed surface of the porous tip 315 and the outlet 307. The nozzle 321 is surrounded by a peripheral wall 322. The exposed surface of the porous tip 315 is recessed into the cavity 321. A function of the nozzle 321 may be to prevent accidental damage to the porous tip 315 and / or reduce this possibility.

FIG. 29 illustrates a cross section of one of the consumables 303 passing through FIG. 28. As described above, the casing 320 of the consumable 303 includes a nozzle 321. In the embodiment of FIG. 29, the nozzle 321 and the housing 320 are a single component. The nozzle 321 includes an inner surrounding wall 322 and a peripheral edge 323. In the embodiment shown in FIG. 29, the nozzle 321 has a conical configuration. Alternatively, the nozzle 321 may have a different configuration, for example, a bell shape (concave side in cross section) or a trumpet shape (convex side in cross section). The nozzle 321 is located downstream of the outlet 307. The nozzle 321 may allow controlling the aerosol smoke flow from the outlet, for example, the shape of the aerosol smoke flow (eg, a second aerosol).

A longitudinal axis 324 of one of the consumables is indicated in FIG. 29. The wall axis 325 of the inner peripheral wall 322 of the nozzle 321 in the longitudinal cross section is also indicated. The opening angle 326 of the nozzle 321 is also indicated. The opening angle 326 of the nozzle 321 is an angle between the longitudinal axis 324 of the consumable 303 and the wall axis 325 of the inner peripheral wall 322 of the nozzle 321.

The opening angle 326 is greater than 0 degrees; preferably greater than 5 degrees; more preferably greater than 10 degrees; more preferably greater than 15 degrees; more preferably greater than 20 degrees; more preferably greater than 25 degrees; more preferably greater than 30 degrees More preferably greater than 35 degrees; more preferably greater than 40 degrees; more preferably greater than 45 degrees; more preferably greater than 50 degrees; more preferably greater than 55 degrees; more preferably greater than 60 degrees; more preferably greater than 65 degrees; More preferably greater than 70 degrees; more preferably greater than 75 degrees; more preferably greater than 80 degrees; more preferably greater than 85 degrees.

The opening angle 326 of the nozzle 321 can be selected independently of the above values. For example, the opening angle 326 of the nozzle 321 may be between 30 degrees and 60 degrees; or between 40 degrees and 50 degrees.

Figure 30 illustrates a longitudinal cross-section through a consumable 303 according to the present invention. The consumable 303 includes a housing 320. For example, the housing 320 may be formed from a substantially rigid plastic material. The display porous tip 315 is located within a pointed housing 317. One of the porous tips 315 downstream of the porous surface 318 is exposed to the airflow through the airflow channel 308.

FIG. 30 is a longitudinal cross-section, so it should be noted that the airflow channel is annular around the porous member 315. In other words, there is an air flow channel 308 surrounding the entire circumferential surface of the exposed surface 318 of the porous member 315. An annular airflow channel having a porous surface 318 surrounding the porous member 315 increases the available surface area from which a second (fragrance) aerosol is generated.

Figure 30 also shows the taper of the porous tip 315. The taper of the porous tip 315 is along the longitudinal axis of the consumable 303. The tapering of the porous tip 315 corresponds to a narrowing in the upstream to downstream direction. In other words, the downstream portion of the porous tip 315 is narrower than the upstream portion of the porous tip 315. It should be apparent that the tapered portion of the porous tip 315 is tapered. In the example of FIG. 30, the porous surface 318 corresponds to the outer surface of the tapered portion of the porous tip 315.

The porous tip 315 has a circular cross-section, however, other cross-sectional shapes are possible. For example, oval, rectangular, square, or triangular.

Figure 30 also shows a Venturi pore 319 formed between the porous surface 318 of the porous tip 315 and one of the shells 320 immediately adjacent the opening. Venturi pore 219 is an annular pore. The narrowest portion of the airflow channel passes through the venturi pore 320, thereby creating a low pressure region in the airflow channel 308 adjacent to the porous surface 318 of the porous tip 315. The Venturi pore 320 is located at the exit 307 of the consumable 303. In the example of FIG. 30, the downstream tip of the porous tip 315 protrudes through the outlet 307 and the Venturi pore 320.

Figure 31 illustrates a longitudinal cross-section through a consumable 303 according to the present invention. The consumable 303 includes a porous tip 315 located within the airflow channel 308. Around the porous surface 318 of the porous tip 315, the air flow channel 308 is annular. The housing 320 and the porous tip 315 form a venturi 319 located adjacent to the outlet 307 of the consumable 303. As far as the porous tip 315 is concerned, the consumable 303 shown in FIG. 31 operates in the same manner as described for the consumable 303 shown in FIGS. 29 and 30.

Figure 32 illustrates a schematic cross section through an outlet portion of a consumable 303 according to the present invention. A porous tip 315 is shown extending into a venturi pore 319 formed by an opening in the housing 320 of the consumable 303. In this embodiment, the downstream tip of the porous member 315 is located in the outlet and in a low-pressure region formed by the venturi pore 319. The air flow channel 308 has an annular portion surrounding the porous surface 318 of the porous tip 315.

Figure 32 illustrates the minimum distance 327 between the porous surface 318 of the porous tip 315 and the adjacent and opposed walls of the housing 320. In this embodiment, the adjacent wall is the wall of the outer shell 320 that defines the perimeter of the Venturi pore 319. The minimum distance 327 between the porous surface 318 of the porous tip 315 and the adjacent and opposite walls 320 may be referred to as the "contact distance", which means the distance to the closest point.

The contact distance 327 may be less than 1000 microns (micrometre or micron), preferably less than 900 microns, more preferably less than 800 microns, more preferably less than 700 microns, more preferably less than 600 microns, more preferably less than 500 microns, more preferably Less than 400 microns, more preferably less than 300 microns, more preferably less than 250 microns, more preferably less than 200 microns, more preferably less than 150 microns, more preferably less than 100 microns, more preferably less than 50 microns, more preferably Less than 30 microns, more preferably less than 15 microns.

The contact distance 327 may be greater than 5 microns (micrometre or micron), preferably greater than 15 microns, more preferably greater than 30 microns, more preferably greater than 50 microns, more preferably greater than 100 microns, more preferably greater than 150 microns, more preferably Greater than 200 microns, more preferably greater than 250 microns, more preferably greater than 300 microns, more preferably greater than 400 microns, more preferably greater than 600 microns, more preferably greater than 700 microns, more preferably greater than 800 microns, more preferably More than 900 microns.

The contact distance 327 can be selected independently of the above values. For example, the contact distance 327 may be between 30 microns and 150 microns; or between 300 microns and 900 microns.

As shown in Figure 32, the cross-section of the consumables shows that the airflow channel 308 has an angled (or inclined) airflow portion 328. An airflow section axis 329 for the left angled section 328 is shown. The airflow portion axis 329 is not a tangible element, but only represents a position of the angled portion 328 in the cross section. A position of a longitudinal axis 324 of the consumable 303 is also shown in FIG. 32. In the longitudinal cross-section, the airflow portion axis 329 and the longitudinal axis 324 of the consumable 303 form a channel angle 330.

The channel angle 330 is less than 90 degrees, preferably less than 85 degrees, more preferably less than 80 degrees, more preferably less than 75 degrees, more preferably less than 70 degrees, more preferably less than 65 degrees, more preferably less than 60 degrees, More preferably less than 55 degrees, more preferably less than 50 degrees, more preferably less than 45 degrees, more preferably less than 40 degrees, more preferably less than 35 degrees, more preferably less than 30 degrees, more preferably less than 25 degrees, more It is preferably less than 20 degrees, more preferably less than 15 degrees, more preferably less than 10 degrees, and more preferably less than 5 degrees.

The channel angle 330 is greater than 0 degrees, preferably greater than 5 degrees, more preferably greater than 10 degrees, more preferably greater than 15 degrees, more preferably greater than 20 degrees, more preferably greater than 25 degrees, more preferably greater than 30 degrees, Better than 35 degrees, better than 40 degrees, better than 45 degrees, better than 50 degrees, better than 55 degrees, better than 60 degrees, better than 65 degrees, more It is preferably greater than 70 degrees, more preferably greater than 75 degrees, more preferably greater than 80 degrees, and even more preferably greater than 85 degrees.

The channel angle 330 can be selected independently of the above values. For example, the channel angle 330 may be between 15 and 45 degrees; or between 55 and 80 degrees.

By having an angled airflow portion 328, the length of the airflow across the porous surface 318 of the porous tip 315 can be increased in each longitudinal unit length of the consumable 303. Therefore, by including the angled airflow portion 328, the effective porous surface area 318 of the porous tip 315 can be increased without increasing the longitudinal length of the consumable 303. This improves the efficiency of the production of the second (fragrance) aerosol.

The length of the angled airflow portion 328 along an airflow direction (along the angled airflow portion 328) may be less than 4 millimeters (mm); preferably less than 3.5 mm; more preferably less than 3.0 mm; more preferably less than 2.5 mm; more preferably less than 2.0 mm; more preferably less than 1.5 mm; more preferably less than 1.0 mm; more preferably less than 0.5 mm.

The length of the angled airflow portion 328 along an airflow direction (along the angled airflow portion 328) may be greater than 0.1 millimeters (mm); preferably greater than 0.5 mm; more preferably greater than 1.0 mm; more preferably greater than 1.5 mm; more preferably 2.0 mm; more preferably 2.5 mm; more preferably 3.0 mm; more preferably 3.5 mm.

The length of the angled airflow portion 328 along an airflow direction (along the angled airflow portion 328) can be selected independently of the above values. For example, the length of the angled airflow portion 328 along an airflow direction (along the angled airflow portion 328) may be between 1.0 mm and 2.5 mm; or between 0.1 mm and 0.5 mm.

In the embodiment shown in FIG. 32, the porous tip 315 is tapered from upstream to downstream along the longitudinal axis 324 of the consumable 303. The portion of the housing 320 opposite to the porous surface 318 of the porous tip 315 is tapered from upstream to downstream along the longitudinal axis 324 of the consumable 303. The tapering of the housing 320 and the tapering of the porous tip 315 generally correspond so that the porous surface 318 of the porous tip 315 in the angled channel is substantially parallel to the immediately adjacent wall of the housing 320. Alternatively, the surface of the wall forming the angled channel 324 may not be parallel to the adjacent porous surface 318.

Alternatively, the cross-section of the surface of the housing opposite to the porous surface 318 of the porous tip 315 may include a substantially pointed configuration whose pointed end points to the porous surface 318 of the porous member 315. In other words, the contact distance is formed between the tip of the housing 320 and the adjacent porous surface of the porous member 315.

33 through 36 illustrate example shapes for a porous tip 315 having a porous surface 318 from which a second (fragrance) aerosol can be generated. In each of FIGS. 33 to 36, the direction of the substantially upstream to downstream airflow along the airflow channel 308 is shown by an arrow.

Figure 33 shows a porous tip 315 having a cylindrical cross-sectional shape along one of its longitudinal lengths. Tip 315 is a passive aerosol generator according to the present invention. The porous surface 318 from which the second (fragrance) aerosol is generated is a cylindrical surface. Therefore, the cross-section of the porous surface 318 is flat, and when the porous tip 315 is located in the consumable 303, it is substantially parallel to the longitudinal axis of the consumable 303. The porous tip 315 shown in FIG. 33 is not tapered.

Figure 34 shows a porous tip 315 with a tapered downstream portion. Tip 315 is a passive aerosol generator according to the present invention. The porous surface 318 from which the second (fragrance) aerosol is generated is a conical surface. Therefore, the cross-section of the porous surface 318 is flat, and when the porous tip 315 is located in the consumable 303, it is angled with respect to the longitudinal axis of the consumable 303. The porous tip 315 shown in FIG. 34 is tapered. The downstream tip of the porous member 315 is substantially sharp.

Figure 35 shows a porous tip 315 with a tapered downstream portion. Tip 315 is a passive aerosol generator according to the present invention. The porous surface 318 from which the second (fragrance) aerosol is generated is a curved conical surface. Therefore, the cross-section of the porous surface 318 is curved. The cross section of the porous surface 318 of the porous tip 315 is convex. The porous tip 315 shown in FIG. 35 is tapered. The downstream tip of the porous member 315 is substantially round.

Figure 36 shows a porous tip 315 with a tapered downstream portion. Tip 315 is a passive aerosol generator according to the present invention. The porous surface 318 from which the second (fragrance) aerosol is generated is a curved conical surface. Therefore, the cross-section of the porous surface 318 is curved. The cross section of the porous surface 318 of the porous tip 315 is convex. The porous tip 315 shown in FIG. 36 is tapered. The downstream tip of the porous member 315 is substantially sharp.

Figure 37 is a cross-section through a replacement passive aerosol generator including a porous enclosure 328 through an alternative passive aerosol generator according to the present invention. The porous enclosure 328 is similar to the porous tip 315, however, the porous enclosure 328 surrounds at least a portion of the airflow channel 308. The air flow along the air flow channel 308 is indicated by an arrow in FIG. 37. The porous enclosure 328 narrows along the longitudinal axis of one of the consumables it is located on, causing the airflow channel 308 to contract. The One Venturi pore 319 is substantially located at the exit 307 of the consumable 303 including the porous enclosure 328. The porous enclosure 328 is configured to produce a second (fragrance) aerosol at one of the porous surfaces 318 of the porous enclosure 328. The porous enclosure 328 is in a consumable having a porous tip 315. The porous enclosure 328 may be an outer porous member, and the porous tip 315 may be an inner porous member.
