Description

Shisha cartridge

The present invention relates to a shisha device and a cartridge containing an aerosol-forming substrate for use in a shisha device; More specifically, it relates to a cartridge for use in a shisha device for heating an aerosol-forming substrate without burning the substrate.

Traditional shisha devices are used to smoke cigarettes and are configured to pass vapors and smoke through a water bath before being inhaled by the consumer. The shisha device may include one outlet or more than one outlet such that the shisha device can be used by more than one consumer at a time. The use of shisha devices is regarded by many as a recreational and social experience.

Cigarettes used in shisha devices can be mixed with other ingredients, for example to increase the volume of steam and smoke produced, to change flavor, or both. Charcoal pellets are typically used to heat tobacco in traditional shisha devices, which can cause complete or partial combustion of tobacco or other ingredients. In addition, charcoal pellets can generate harmful or potentially harmful products such as carbon monoxide, which can be mixed with shisha vapors and passed through water baths.

For example, several shisha devices have been proposed for burning cigarettes using an electric heat source to prevent by-products of burning charcoal or to improve the consistency in which cigarettes are burned. Other Shisha devices have been proposed that use e-liquids other than cigarettes. Shisha devices using e-liquid eliminate combustion by-products, but deprive Shisha consumers of the tobacco-based experience.

Various shisha devices using electric heaters have been proposed to heat an aerosol-forming substrate such as a cigarette without burning the substrate. These shisha devices provide a tobacco-based experience without combustion by-products. However, replacing electric heaters with charcoal can reduce the total aerosol mass produced from the substrate.

Charcoal-operated shisha devices rely on conduction and convection for heat transfer and aerosol generation. Through conduction, the charcoal heats the aerosol-forming substrate to about 200° C., which remains fairly constant throughout the experience. Through convection, the aerosol-forming substrate can be heated to about 230° C., where the air temperature reaches about 700° C. during puffing.

Electric heaters, for example resistive heaters, can provide a similar level of heat transfer through conduction. However, reaching an air temperature of about 700° C. using an electric heater poses a challenge, especially when the Shisha device is powered by a battery. As such, the substrate may not be heated enough to cause significant aerosol generation for a sustained period of time, which may result in less total aerosol mass being generated as compared to a Shisha device using charcoal.

It would be desirable to provide a shisha cartridge containing an aerosol-forming substrate that can be heated by an electric heater in a manner that provides an aerosol production similar to that experienced with a charcoal heated shisha device. More specifically, it would be desirable to provide a cartridge for use in a heated non-combustion shisha device that produces a desired level of aerosol mass.

Various aspects of the invention relate to a shisha cartridge comprising a body defining a cavity. The cartridge includes an aerosol-forming substrate disposed within the cavity. The cartridge includes a heatable surface area. The heatable surface area can be defined by the body. The ratio of the heatable surface area of the cartridge to the volume of the cartridge ranges from about 1 cm ^-1 to about 4 cm ^-1 . For example, the ratio of the heatable surface area to the volume of the cavity is about 1 cm ^-1 to about 2 cm ^-1 , such as about 1.2 cm ^-1 to about 1.6 cm ^-1 or about 1.3 cm ^-1 to about 1.5 cm ^-1 It can be a range. In some embodiments, the heatable surface area is about 25 cm ² to about 100 cm ² , such as about 25 cm ² to about 55 cm ² .

The ratio of the heatable surface area, such as the surface area of the cavity defined by the body, to the volume of the cavity of about 1 cm ⁻¹ or more increases heat transfer by conduction compared to a conventional charcoal operated shisha device. This increases aerosol production. The increase in heat transfer by conduction can overcome or at least partially compensate for insufficient heat transfer by convection in an electrically heated shisha device compared to a conventional charcoal operated shisha device. The ratio of the heatable surface area to the volume of the cavity of about 1 cm ^-1 or more can be particularly useful for increasing aerosol production during the initial puff. This helps to reduce the time between the start of heating of the aerosol-forming substrate and the time the device is ready for the user to take the first puff.

The ratio of the heatable surface area, such as the surface area of the cavity defined by the body, to the cavity volume of about 4 cm ^-1 or less prevents premature depletion of the substrate. In some embodiments, the ratio of the heatable surface area of the body of the cavity to the volume of the cavity is about 1.2 cm ^-1 to about 3 cm ^-1 , such as about 1.5 cm ^-1 to about 3 cm ^-1 , or such as about 2.5 cm ^-1 to about 3 cm ^-1 .

The heatable surface area to volume ratio of the cavity can be easily varied by changing one or more dimensional limitations of the cartridge, such as the length, inner diameter or shape of the body of the cartridge. As used herein, the “inner diameter” of a cartridge refers to the average cross-sectional distance across the cavity as measured through the geometric center of the section. If the cross-section is circular, each measured transverse distance shall be equal to the average transverse cross-sectional distance. However, the cross-section may have any suitable shape, including shapes other than circular. The cartridge may have a different inner diameter along the length of the cartridge, or the inner diameter may be uniform along the length of the capsule.

The heatable surface area can be easily varied by using one or more thermal bridges inside the cavity to increase the heatable surface area. One or more thermal bridges may be provided within the cavity of the cartridge.

The cartridge can be of any suitable shape configured to be received by the shisha device. The shisha device is configured to heat the aerosol-forming substrate in the cartridge, preferably by conduction. The cartridge is preferably shaped and sized to allow contact or minimize the distance between the heating elements of the shisha device to provide efficient heat transfer from the shisha's heater to the aerosol-generating substrate in the cartridge.

The cartridge may have a substantially cubic shape, a cylindrical shape, a truncated cone shape, or any other suitable shape. Preferably, the cartridge has a generally cylindrical shape or a truncated conical shape.

When the cartridge has a truncated conical shape, in some embodiments, the sidewalls of the cartridge body deviate from the longitudinal axis at an angle of about 2° to about 45°, preferably at an angle of about 3° to about 5°. In some embodiments, the sidewalls of the cartridge body deviate from the longitudinal axis at an angle of about 4.5°.

The cartridge may comprise any suitable body defining a cavity in which the aerosol-forming substrate is disposed. The body is preferably formed from one or more heat resistant materials such as heat resistant polymers or metals. Preferably, the body comprises a thermally conductive material. For example, the body may comprise any one of aluminum, copper, zinc, nickel, silver, any alloys thereof, and combinations thereof. Preferably, the body comprises aluminum.

The body may include a top, a bottom and a side wall.

In some embodiments, the bottom can be a flat bottom. In some embodiments, the bottom can be a substantially planar bottom. In some implementations, the bottom may transition to the sidewall in a single transition, for example through a vertex or curved edge.

In some embodiments, the bottom is generally planar or not flat. In some embodiments, the bottom deviates at an angle from the flat bottom. The angle can be about 5° to about 40°, such as about 10° to about 30°, preferably about 15° to about 25° or about 15° to about 20°, such as 18°. In some embodiments, the bottom is deviated from the flat portion by the intermediate transition medium, which provides a first transition between the sidewall and the intermediate transition medium and a second transition between the intermediate transition region and the bottom. In some implementations, the intermediate transition medium can be angled relative to the rest of the bottom. The angle can be about 5° to about 40°, such as about 10° to about 30°, preferably about 15° to about 25° or about 15° to about 20°, such as 18°. The rest of the bottom can be substantially flat. The remaining portion of the bottom may be substantially planar. The intermediate transition may lie in a plane intersecting both the plane of the rest of the lower region and the plane of the sidewall. The angle in the plane of the middle transition and the rest of the lower region is from about 5° to about 40°, such as from about 10° to about 30°, preferably from about 15° to about 25° or from about 15° to about 20°, For example, it may be 18°. The intermediate transition may be a beveled edge in some embodiments.

The body may include one or more portions. For example, the side wall and the bottom may be a single part or two parts configured to engage each other in any suitable manner, such as a screw fit or an interference fit. The top and side walls may be a single part or two parts configured to engage each other in any suitable manner, such as a screw fit or an interference fit.

The body defines a cavity in which the aerosol-forming substrate can be placed. The portion of the body defining the cavity has a heatable surface area. As used herein, “heatable surface area” refers to the area of a surface through which heat applied at a location other than the area of the surface can be transferred to the area of the surface. For example, the heatable surface area of a portion of the body defining the cavity is the surface area through which heat can be transferred from the outside of the cavity through the cavity to the surface of the body defining the cavity. For example, the heatable surface area of a portion of the body defining the cavity is the surface area inside the cavity through which heat can be transferred from outside of the cavity, such as the outer surface area of the body, through the body to the surface of the body defining the cavity. For example, heat may be applied to the outer surface area of the body, and this heat may be transferred to the cavity from the heatable surface area of the surface area of the cavity defined by the body. The heatable surface area may be a heatable surface area in the lateral direction. The heatable surface area may be a heatable surface area in the radial direction. Preferably, the heatable surface area has a thermal conductivity of at least about 100 Wm ^-1 K ^-1 . More preferably, the heatable surface area has a thermal conductivity of at least about 150 Wm ^-1 K ^-1 , such as at least about 200 Wm ^-1 K ^-1 .

The heatable surface area can have any suitable total surface area provided the ratio of the heatable surface area to the cavity is in the range of about 1 cm ^-1 to about 4 cm ^-1 . In some embodiments, the ratio of the heatable surface area to the volume of the cavity ranges from about 1.2 cm ^-1 to about 3 cm ^-1 . Preferably, the ratio of the heatable surface area to the volume of the cavity ranges from about 1.5 cm ^-1 to about 3 cm ^-1 , such as from about 2.5 cm ^-1 to about 3 cm ^-1 . In some preferred embodiments, the ratio of the heatable surface area to the volume of the cavity is about 1 cm ^-1 to about 2 cm ^-1 , such as about 1.2 cm ^-1 to about 1.6 cm ^-1 or about 1.3 cm ^-1 to about 1.5 cm ^{It is in the -1} range.

In order to achieve this heatable surface area to volume ratio, the body can be long and narrow, or short and wide. The cartridge may include one or more elements or features within the cavity to increase the heatable surface area within the cavity. For example, the sidewall can include one or more pins extending into the cavity. The cartridge may include a thermal bridge within the cavity. Preferably, the thermal bridge is positioned within the cavity such that the aerosol-forming substrate is disposed within the cavity in contact with the thermal bridge on the opposite major surface. In some embodiments, the thermal bridge may comprise the same material as the body. In some embodiments, the thermal bridge may comprise a different material than the body. The thermal bridge can be thermally connected with other parts of the body. For example, the thermal bridge may be in thermal contact with one or more of the top, bottom and side walls. In some embodiments, the thermal bridge extends from one portion of the sidewall to another portion of the sidewall. In some embodiments, the thermal bridge may not be in contact with the sidewall. When a thermal bridge is provided within the cavity, the thermal bridge forms part of the heatable surface area of the cartridge. In some embodiments, one or more thermal bridges may be provided.

The thermal bridge can have any suitable shape. For example, a thermal bridge can form a cylinder. The cylinder can be in the cavity. The cylinder may be concentric with a cavity such as a side wall of the body. The thermal bridge may be in thermal contact with the top or bottom of the body. The thermal bridge may include one or more additional thermal bridges extending from the sidewalls to the cylindrical thermal bridges or capable of contacting one or more of the top, bottom and sidewalls.

In some embodiments, the thermal bridge is substantially rectangular and extends from one portion of the sidewall to another portion of the sidewall. In some embodiments, the thermal bridge comprises an S-shaped cross section and extends from one portion of the sidewall to another portion of the sidewall. The thermal bridge preferably has a thermal conductivity as high as at least a portion of the body, such as the side wall, the bottom or the top to which the thermal bridge contacts. Preferably, the thermal bridge has a greater conductivity than the portion of the body that the thermal bridge contacts. Thermal bridges may divide the cavity into more than one compartment. Preferably, the compartments are dimensioned sufficiently large to allow the aerosol-forming substrate to easily occupy at least a portion of each compartment to allow contact between the thermal bridges and opposing major surfaces of the aerosol-forming substrate.

Typically, molasses will contain less than about 60 weight percent sugar, such as less than about 50 weight percent sugar.

Aerosol-forming substrates for use with traditional shisha devices are in the form of molasses, which are not homogeneous and may contain lumps and cavities. These cavities prevent direct thermal contact between the substrate and the heated surface, making heat conduction particularly inefficient. As a result, electronic heated shisha devices tend to deviate from traditional molasses, for example by using e-liquid or dry stones. Due to the ratio of the heated surface area to the volume of the cavity of the cartridge described in this application, more traditional aerosol-forming substrate molasses can be used to preserve the conventional procedures and shisha experience while using electric heating.

Preferably, the shisha device is configured to sufficiently heat the aerosol-generating substrate in the cartridge such that it causes the formation of an aerosol from the aerosol-forming substrate but does not burn the aerosol-forming substrate. For example, the shisha device may be configured to heat the aerosol-forming substrate to a temperature in the range of about 150°C to about 300°C, more preferably about 180°C to about 250°C, or about 200°C to about 230°C.

The shisha device is preferably configured to heat the cartridge. The shisha device may include a receptacle for receiving the cartridge. The shisha device includes a heating element configured to contact the body of the cartridge when the cartridge is received in the receptacle or configured to be proximate to the body of the cartridge. The heating element can form at least a portion of the receptacle. The heating element may form at least a portion of the surface of the receptacle. The shisha cartridge may be configured to transfer by conduction from the heating element to the aerosol-forming substrate within the cavity. In some embodiments, the heating element comprises an electric heating element. In some implementations, the heating element includes a resistive heating component. For example, the heating element can include one or more resistance wires or other resistance elements. The resistive wire can contact the thermally conductive material to distribute the heat generated over a larger area.

For the purposes of this disclosure, if the resistive wire is in contact with the thermally conductive material, both the resistive wire and the thermally conductive material are part of the heating element. The heating element may form at least a portion of the surface of the receptacle.

The shisha device may include control electronics operably coupled to the heating element to control the heating of the heating element and thus the temperature at which the aerosol-forming substrate in the cartridge is heated. The control electronics may be provided in any suitable form and may include, for example, a controller or a memory and a controller.

Functions attributed to the control electronic device in the present disclosure may be implemented in one or more of software, firmware, and hardware.

The electronic circuit may include a microprocessor, which may be a programmable microprocessor. The electronic circuit can be configured to regulate the power supply. Electric power can be supplied to the heater element in the form of current pulses.

In some embodiments, the control electronics may be configured to monitor the electrical resistance of the heating element and to control the supply of power to the heating element according to the electrical resistance of the heating element. In this way, the control electronics can regulate the temperature of the resistive element.

The shisha device may include a temperature sensor such as a thermocouple operably coupled to the control electronics to control the temperature of the heating element. The temperature sensor can be located in any suitable location. For example, the temperature sensor may be configured to be inserted into the cartridge when received inside the receptacle to monitor the temperature of the aerosol-forming substrate to be heated. Additionally or alternatively, the temperature sensor can be in contact with the heating element. Additionally or alternatively, a temperature sensor may be positioned to detect the temperature at the aerosol outlet of the shisha device or a portion thereof. The sensor can transmit a signal regarding the sensed temperature to the control electronics to adjust the heating of the heating element to achieve a suitable temperature at the sensor.

The control electronics can be operably coupled to the power supply. The shisha device can include any suitable power supply. For example, the power supply of the shisha device may be a battery or a set of batteries. The battery of the power supply may be rechargeable, removable and replaceable, or rechargeable and removable and replaceable. Any suitable battery can be used. For example, there are large batteries or standard batteries such as those used in industrial large power tools. Alternatively, the power supply may be any type of electrical power supply including super or hyper capacitors. Alternatively, the assembly can be connected to an external electrical power source and designed for this purpose electrically and electronically. Regardless of the type of power source used, the power supply is preferably recharged or the normal function of the assembly during at least one shisha session until the aerosol is depleted from the aerosol-forming substrate in the cartridge before it needs to be connected to an external power source. Provides enough energy for it. Preferably, the power supply provides sufficient energy for normal functioning of the assembly for at least about 70 minutes of continuous operation of the device before it needs to be recharged or connected to an external power source.

In one embodiment, the shisha device includes an aerosol generating element comprising a cartridge receptacle, a heating element, an aerosol outlet, and a fresh air inlet. The cartridge receptacle is configured to receive a cartridge containing an aerosol-forming substrate. The cartridge may be as described above. The heating element can define at least a portion of the receptacle surface.

The shisha device includes a fresh air inlet channel in fluid communication with the receptacle. In use, fresh air flows through the fresh air inlet channel to the receptacle and through a cartridge placed within the receptacle. Fresh air flowing through the cartridge is entrained with the aerosol generated from the aerosol-forming substrate in the cartridge. Fresh air entrained with the aerosol flows into the aerosol.

The fresh air inlet channel may include one or more apertures passing through the cartridge receptacle such that fresh air from outside the shisha device can flow through the channel and through the one or more apertures into the cartridge receptacle. If the channel includes more than one aperture, the channel may include a manifold for directing air flowing through the channel to each aperture. Preferably, the shisha device comprises at least two fresh air inlet channels.

As noted above, the cartridge includes one or more inlets formed in the housing to allow airflow through the chamber of the cartridge when in use. If the receptacle includes one or more inlet apertures, at least some of the inlets in the cartridge may be aligned with the aperture at the top of the receptacle. The cartridge may include an alignment feature configured to engage a complementary alignment feature of the receptacle to align the inlet of the cartridge with an aperture of the receptacle when the cartridge is inserted into the receptacle.

Air entering the cartridge flows across the aerosol-forming substrate, entrains the aerosol, and exits the cartridge and receptacle through the aerosol outlet. From the aerosol outlet, air carrying the aerosol enters the vessel of the Shisha device.

The shisha device may include any suitable container defining an interior volume configured to contain a liquid and defining an outlet in the headspace above the liquid fill level. The container may include an optically clear or opaque housing to allow a consumer to view the contents contained in the container. The container may comprise a liquid fill boundary, such as a liquid fill line. The container housing can be formed from any suitable material. For example, the container housing may comprise glass or a suitable rigid plastic material. Preferably, the container is removable from a portion of the shisha device comprising the aerosol generating element so that the consumer can fill, empty or clean the container.

The container can be filled to a liquid fill level by the consumer. The liquid preferably comprises one or more colorants, flavoring agents or water to which colorants and flavoring agents may be optionally injected. For example, water may be infused with either or both vegetable or herbal infusions.

The aerosol entrained in air exiting the aerosol outlet of the receptacle can move through a conduit located within the container. The conduit may be coupled to the aerosol outlet of the aerosol-generating element of the shisha assembly and may have an opening below the liquid fill level of the container such that the aerosol flowing through the container flows through the opening of the conduit, and then through the liquid. It flows into the headspace and exits through the headspace outlet for delivery to the consumer.

The headspace outlet may be coupled to a hose containing a mouthpiece to deliver the aerosol to the consumer. The mouthpiece may include a switch activatable by a puff sensor operably coupled to the user or the control electronics of the shisha device. Preferably, the switch or puff sensor is wirelessly coupled to the control electronics. Activation of a switch or puff sensor may cause the control electronics to activate the heating element rather than continuously supplying energy to the heating element. Thus, the use of a switch or puff sensor can serve to save energy compared to devices that do not use these elements to provide heating on demand rather than constant heating.

For purposes of example, one method of using a shisha device as described herein is provided below in chronological order. The container can be separated from the other components of the shisha device and filled with water. One or more of natural fruit juices, vegetable infusions and herbal infusions may be added to the water for flavor. The amount of liquid added must cover a portion of the conduit, but must not exceed the fill level mark that may be optionally present in the container. The container is then reassembled into the shisha device. A portion of the aerosol-generating element can be removed or opened to allow the cartridge to be inserted into the receptacle. The aerosol-generating element is then reassembled or closed. The device can then be turned on. Turning on the device initiates the heating profile of the heating element so that the aerosol-forming substrate can be heated at or above the vaporization temperature of the aerosol-forming substrate, but below the combustion temperature of the aerosol-forming substrate. The user can puff the mouthpiece as desired. The user can continue to use the device until the aerosol is no longer visible or delivered. In some embodiments, the device will automatically shut off when the cartridge runs out of usable aerosol-generating substrate. In some implementations, the consumer may refill the device with a new cartridge, for example after receiving a signal from the device that the aerosol-forming substrate in the cartridge is depleted or nearly depleted. Once refilled with a new cartridge, the device can continue to be used. Preferably, the shisha device can be switched off at any time by the consumer, for example by switching off the device.

The shisha device can perform any suitable air management. In one embodiment, the puffing action from the user will create an inhalation effect, causing a low pressure inside the device that will cause external air to flow through the air inlet of the device, into the fresh air inlet channel, and into the receptacle. Air can then flow through the cartridge in the receptacle to carry the aerosol generated from the aerosol-forming substrate. The air with the entrained aerosol then exits the aerosol outlet of the receptacle and flows through the conduit to the liquid inside the container. The aerosol will then be foamed out of the liquid for delivery to the consumer and into the headspace of the container above the liquid level, from the headspace outlet and through the hose and mouthpiece. The flow of external air and the flow of aerosol inside the shisha device can be driven by a puffing action from the user.

The cartridge 200 has a length (l) and a width (w) referred to herein as an inner diameter. The cartridge 200 has a heatable surface area S _H inside the cavity 215, which is by the heating element of the shisha device, to the outside of the body, for example to the aerosol-forming substrate 300 in the cavity 218. It is the surface area that can transfer the applied heat.

The aerosol-forming substrate 300 occupies a volume within the cavity 218. Preferably, the ratio of the volume of the aerosol-forming substrate 300 in the cavity 218 to the heatable surface area (S _H ) of the body 210 in the cavity 218 ranges from about 1 cm ^-1 to about 4 cm ^-1. to be. This ratio allows the aerosol-forming substrate 300 to generate a desired amount of aerosol mass without premature depletion of the aerosol-forming substrate 300.

Referring now to Figures 3 and 4, the top 215 and bottom 213 of the body may have a plurality of apertures 217, 216 that allow airflow through the cartridge when the cartridge is in use. The apertures 216 and 217 of the top 215 and the bottom 213 may be aligned. Apertures 217 and 216 can be blocked when the cartridge is stored prior to use. For example, apertures 216 and 217 may be blocked by a releasable liner (not shown).

The thermal bridge 220 contacts the lower end 213 of the cartridge 200. The thermal bridge 220 increases the heatable surface area S _H in the cavity 218 for cartridges of the same dimension that do not include the thermal bridge.

8 and 9 are schematic cross-sectional views of the cartridge 200. The cartridge 200 has a side wall 212, a top 215, and a bottom 213 together defining a cavity 218 in which an aerosol-generating substrate (not shown) may be disposed. The cartridge 200 of FIG. 8 includes a generally flat bottom 213 with a slightly rounded edge, and the cartridge 200 of FIG. 9 includes a generally truncated conical bottom 213. In contrast, the cartridge 200 of FIGS. 8 and 9 is substantially the same.

The flange 219 rests on the shoulder of the receptacle of the shisha device so that the cartridge 200 can be easily removed from the receptacle after use by gripping the flange. The flange may also help prevent excessive insertion of the cartridge 200 into the receptacle.

The cavity 218 has a maximum inner width Wt and a height h. In the case of the truncated conical cartridge 200, the maximum inner width Wt may be substantially at the top of the cartridge 200. In the example illustrated in FIG. 8, the maximum inner width Wt may be about 2.98 cm, and the height h may be about 3.63 cm. The lower end of the cavity 218 has a width Wb. The width of the lower end of the cavity Wb may be about 2.43 cm.

The lower end 213 of the container 200 of FIG. 9 is generally truncated conical. As can be seen in FIG. 9, the width Wb is generally measured at a position where the angle of the sidewall 212 changes the plane. In some implementations, such as the example of FIG. 9, the sidewalls of the bottom portion 213 deviate from the flat bottom at an angle β. The angle β may be about 18°. The width Wc of the smaller lower portion may be about 0.84 cm. Wc can be measured at a longitudinal position where the width of the cavity is minimal.

Example

Example 1: Cylindrical cartridge

Presented below are non-limiting examples illustrating the effect of various cartridge designs on the generation of aerosols from an aerosol-forming substrate disposed on a shisha cartridge. Each cartridge contains 10 g of commercially available tobacco molasses (Al-Fakher) with a calculated volume of about 31.5 cm ³ .

Three cartridge designs are tested. Each cartridge is cylindrical and made of aluminum. The cartridge has a length of 55 mm and an inner diameter of 27 mm. One cartridge does not contain a thermal bridge and has a heatable surface area (S _H ) of about 52 cm ^{2 in} the cavity. Another cartridge included a T-shaped 0.2 mm thick copper plate (see FIGS. 11A-11D ), which spanned the cavity to provide a total S _H of about 69 cm ² . Another cartridge further includes a 0.2 mm thick copper plate with an S-shaped cross section spanning the cavity (see FIG. 12) to provide an S _H of about 90 cm ² .

The cartridge is placed in communication with the conduit. A truncated conical nozzle made of high temperature epoxy resin with an outlet orifice of 3 mm is included in the conduit. The outlet orifice of the nozzle was about 55 mm from the cartridge outlet. The conduit extends below the liquid level in the container. Above the liquid level of the container, an aerosol is collected that exits the outlet in communication with the headspace.

The cartridge is heated using a wire wound heating element set to a constant temperature of 200°C.

The generated aerosol was collected using a total of 10 Cambridge pads whose weight was recorded before and after the Shisha experience. The total duration of the experience corresponds to 105 puffs. To achieve the desired puffing experience, four programmable dual syringe pumps (PDSPs) manufactured by Pomac BV (Tolbert, Groninen, Netherlands) were used simultaneously to create the following puffing regime:

퍼프 체적: 530 mL

Puff volume: 530 mL

퍼프 지속기간: 2600 ms

Puff duration: 2600 ms

퍼프 사이의 지속기간: 17초

Duration between puffs: 17 seconds

The experimental setup was arranged so that only 2 out of 10 Cambridge pads collect aerosols generated at a given moment. Every 21 puffs, a check valve ensured that the aerosol was converted to the correct pair of Cambridge pads. Consequently, the production of aerosols can be monitored as a function of time.

The evaporated mass of molasses was determined by comparing the weight of molasses before and after the Shisha experience.

In addition, the total aerosol mass and evaporated mass were determined for charcoal operated shisha using similar conditions.

Results from various cartridge designs are shown in Figure 13 and Table 1. In Figure 13, the TAM per puff is shown after the initial 20 puffs. In Fig. 13, the curve indicated by (1) represents the result from the charcoal operated shisha device, the curve indicated by (2) represents the cartridge with S _H of about 52 cm ² , the curve indicated by (3) is about denotes a cartridge having an S _H of 69 cm ^2, the curve indicated by (4) shows a cartridge having a S _H of about 90 cm ^2.

Table 1. TAM and evaporated mass

The test cartridges S _H of the volume of (for = 52 cm ² of the cartridges S _H), 1.5 cm ^-1 to (S _H = 90 cm for ² cartridge) 3 cm ^-1 of the aerosol forming substrate (tobacco molasses) Has a ratio of

The charcoal operated shisha used in these experiments consumed 3.5 g with 25 cm ² of S _H. Since the heat transfer through convection is much smaller in the electric shisha, only 2.8 g is consumed for S _H = 52 cm ² . As a result, the total TAM collected for the electrically heated shisha is only about 80% of the charcoal operated shisha for this cartridge (1700 mg vs. 1370 mg). In particular, the aerosol mass production was substantially small compared to the 12.7 mg/puff obtained by charcoal operated shisha during the first 21 puffs where 8.7 mg/puff of TAM was collected for the S _H = 52 cm ² cartridge. However, when S _H is increased to 90 cm ² , the result obtained by the electric shisha becomes a value similar to that of the charcoal operated shisha. In this case, the consumption of molasses increased to 3.9 g and the total TAM was collected as 1850 mg, and the TAM collected during the first puff increased to 12.0 mg/puff.

Reference is made to FIG. 14 to illustrate design considerations for achieving the desired ratio of S _{H to} volume of the aerosol-forming substrate. In Fig. 14, the bottom trace shows the calculated S _H for cylinders with a volume of 31.5 cm ³ of different diameter. The corresponding length is shown in the upper x-axis. The calculated results show that if no thermal bridge is used, a cartridge with a length of almost 18 cm is required to achieve an S _H of 90 cm ² . However, this length is not practical for most shisha devices.

The trace marked D/3 is calculated for a cylinder with the same dimensions as the bottom trace, but represents the calculated S _H for a cylinder with a cylindrical heat bridge with a diameter equal to 1/3 of the diameter of the cartridge. The trace marked D/2 is calculated for a cylinder with the same dimensions as the bottom trace, but represents the calculated S _H for a cylinder with a cylindrical heat bridge with a diameter equal to half the diameter of the cartridge. As shown, the thermal bridge rapidly increases S _H to provide a cartridge with more desirable dimensions. For example, the cartridge may have a length of less than 10 cm and may have an S _H of 90 cm ² .

Example 2: truncated conical cartridge

The effect of cartridge geometry on various performance aspects was tested. The performance of cartridges with various truncated cone designs were compared with cylindrical cartridges.

The cartridge was cylindrical and made of aluminum. The cylindrical cartridge had a length of 41.25 mm and an inner diameter of 27 mm (C 27). The truncated conical cartridges each had a length of 41.25 mm and a top inner diameter of 27 mm. The lower inner diameters of the truncated conical cartridge were 22 mm (LD 22), 18 mm (LD 18) and 14 mm (LD 14). The top and bottom of each cartridge contain 19 holes, and each hole has a 2 mm diameter.

The substrate temperature and the total aerosol mass produced from each cartridge were tested as shown in Example 1 above.

In one experiment, each cartridge contained 10 g of commercially available tobacco molasses (Al-Fakher), and the temperature of the substrate was monitored as the cartridge was heated and the time for the substrate to reach 80° C. was determined. The results are presented in Table 2 below.

Table 2: Amount of time for the substrate to reach 80°C.

The time to reach 80° C. can be directly related to the time to the first puff. Thus, the cylindrical cartridge C 27 can allow for a faster initial heating and can take the first puff more quickly. However, the longer times associated with truncated conical cartridges LD 22, LD 18, and LD 14 may more closely mimic the time to first puff associated with conventional charcoal-based shisha devices, and thus the specificity of such conventional devices. You can maintain the conscious side.

In another experiment, C 27, LD 22, and LD 18 cartridges containing 10 g of molasses were heated and the total aerosol mass and the mass of evaporated molasses were determined. For the C 27 cartridge, the LD 22 cartridge was heated for an additional 30 seconds prior to testing and the LD 18 cartridge was heated for an additional 60 seconds based on the results presented in Table 2 above.

The mass of evaporated molasses is shown in FIG. 15, and the total aerosol mass produced is shown in FIG. As shown in Fig. 16, the largest total aerosol mass was observed in the LD 22 cartridge. As shown in Fig. 15, the amount of evaporated molasses increased as the diameter of the cartridge decreased.

In another experiment, total aerosol mass and evaporated molasses were measured for a C 27 cartridge containing 10 g molasses and an LD 22 cartridge containing 10 g, 8 g and 6 g molasses. For the C 27 cartridge, the LD 22 cartridge was heated for an additional 30 seconds prior to testing based on the results presented in Table 2 above.

The mass of evaporated molasses is shown in FIG. 17, and the total aerosol mass produced is shown in FIG. 18. As shown in Fig. 18, the total aerosol mass was similar between the LD 22 cartridges containing 10 g and 8 g molasses, suggesting that less molasses could be used. In addition, the LD 22 cartridge containing 6 g of molasses was shown to increase the aerosol mass for the first 60 puffs compared to the C 27 cartridge containing 10 g of molasses, which indicates that the shape of the cartridge increases the total aerosol generation and It is suggested that it may have a substantial effect on the amount of molasses that can be used.
