Description

The present invention relates to a shisha device and a cartridge containing an aerosol-forming substrate for use in a shisha device, and more specifically, to a cartridge for use in a shisha device that heats an aerosol-forming substrate without burning the substrate.

Traditional shisha devices are used to smoke cigarettes and are configured to allow vapors and smoke to pass through the basin before the consumer inhales. The shisha device may include one outlet, or may include two or more outlets so that two or more consumers can use the device at the same time. For many, the use of shisha devices is considered a leisure activity and a social experience.

The tobacco used in the shisha device may be mixed with other ingredients, for example, to increase the amount of vapor and smoke produced, to change the flavor, or both. Typically, in conventional shisha equipment, charcoal pellets are used to heat the tobacco, which can burn the tobacco or other components completely or partially. In addition, charcoal pellets can produce harmful or potentially harmful products such as carbon monoxide that can mix with shisha vapor and pass through the basin.

Some shisha devices have been proposed to burn tobacco using an electric heat source, for example to avoid by-products of charcoal burning or to improve the consistency of tobacco burning. Other shisha devices that use e-liquid rather than tobacco have been proposed. Shisha devices that use e-liquids produce no by-products of combustion, but deprive shisha consumers of a tobacco-based experience.

Various shisha devices have been proposed that use an electric heater to heat an aerosol-forming substrate such as tobacco without burning the substrate. Such shisha devices provide a tobacco-based experience without the by-products of combustion. However, substituting charcoal with an electric heater can reduce the total aerosol mass produced from the substrate.

Charcoal-operated shisha devices rely on conduction and convection for heat transfer and aerosol production. Through conduction, the charcoal heats the aerosol-forming substrate to a temperature of up to about 200 ° C., which remains nearly constant throughout the experience. Through convection, the aerosol-forming substrate is heated up to about 230 ° C. and the air temperature during smoke absorption can reach up to about 700 ° C.

For example, an electric heater, such as a resistance heater, can provide a level of heat transfer similar to heat transfer through conduction. However, reaching an air temperature of about 700 ° C. with an electric heater poses a problem, especially if the shisha device is battery operated. As a result, the substrate may not be heated sufficiently to produce substantial aerosol production for a sustained period, which reduces the production of total aerosol mass compared to a shisha device that uses charcoal. Can bring.

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

The ratio of heatable surface area, such as the surface area of the recess defined by the body, to the volume of the recess, about 1 cm ^{-1 or more, increases conduction heat transfer compared to conventional charcoal-operated shisha devices.} This increases aerosol production. Increased heat transfer due to conduction can overcome, or at least partially compensate for, the absence of convective heat transfer in electrically heated shisha devices, as opposed to conventional charcoal-operated shisha devices. A ratio of heatable surface area to indentation volume of about 1 cm- ¹ or greater can be particularly useful in increasing aerosol production during initial smoke absorption. This helps reduce the time between the time when the aerosol-forming substrate begins to heat and the time when the user is ready for the first smoke absorption.

The ratio of the heatable surface area, such as the surface area of the recess defined by the body, to the volume of the recess, such as 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 recess to the volume of the recess is about 1.5 cm ^-1 to about 3 cm ^-1 , or about 2.5 cm ^-1 to about 3 cm ^-1 .

The heatable surface area relative to the volume ratio of the indentation can be easily varied by changing one or more dimensional constraints 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 means the average transverse cross-sectional distance across a recess as measured through the geometric center of the section. When the cross section is circular, each measured cross section distance is the same as the average cross section distance. However, the cross section may have any suitable shape, including shapes other than circular. The cartridges may have different inner diameters along the length of the cartridge, or the inner diameters may be uniform along the length of the capsule.

The heatable surface area can be easily varied by increasing the heatable surface area using one or more thermal bridges inside the indentation. One or more thermal bridges may be provided inside the indentation of the cartridge.

The cartridge may contain one or more elements or features within the recess to increase the heatable surface area within the recess. For example, the sidewall may include one or more fins extending into the recess. The cartridge may contain a thermal bridge within the recess. The thermal bridge is preferably positioned within the recess so that the aerosol-forming substrate disposed within the recess can contact the thermal bridge on the opposing main surface. In some embodiments, the thermal bridge may contain the same material as the body. In some embodiments, the thermal bridge may contain a material different from that of the body.

In some embodiments, the thermal bridge comprises an S-shaped cross section that extends from one part of the side wall to the other part of the side wall. The thermal bridge preferably has a higher thermal conductivity as at least a part of the main body, such as a side wall, a bottom, or a top with which the thermal bridge contacts. The thermal bridge preferably has a higher conductivity than a part of the main body with which the thermal bridge is in contact. A thermal bridge can divide a depression into multiple compartments.

It is preferable to provide sufficient energy for the normal functioning of the. The power source preferably provides sufficient energy for the normal functioning of the assembly for at least about 70 minutes of continuous operation of the device before it requires recharging or connection to an external power source.

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

The shisha device includes a fresh air inlet channel that fluidly connects to the receptacle. During use, outside air flows through the outside air inlet channel to the receptacle and through a cartridge located within the receptacle. The outside air flowing through the cartridge is mixed with the aerosol generated from the aerosol-forming substrate in the cartridge. The outside air mixed in the aerosol flows into the aerosol.

The outside air inlet channel may include one or more openings through the cartridge receptacle so that outside air from the outside of the shisha device can flow through the channel and into the cartridge receptacle through one or more openings. If the channel has more than one opening, the channel may include a manifold to direct the air flowing through the channel to each opening.

Air entering the cartridge flows across the aerosol-forming substrate, mixes the aerosol, and exits the cartridge and container via 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 vessel that defines an internal volume configured to contain the liquid and defines an outlet in the upper space above the liquid filling level. The vessel may include an optically transparent or opaque housing that allows the consumer to observe the contents contained within the vessel.

Aerosols mixed in the air exiting the receiving aerosol outlet can travel through conduits located within the vessel. The conduit is a shisha assembly so that the aerosol flowing through the vessel passes through the opening of the conduit, then through the liquid, into the upper space of the vessel, exits the upper space exit, and is delivered to the consumer. It may be coupled to the aerosol outlet of the aerosol generating element of the vessel and may have an opening below the liquid filling level of the vessel.

The upper space outlet may be connected to a hose with a mouthpiece for delivering the aerosol to the consumer. The mouthpiece may include a switch that can be activated by the user or by a smoke absorption sensor operably connected to the control electronics of the shisha device. The switch or smoke absorption sensor is preferably wirelessly connected to the control electronic circuit. Activating a switch or smoke sensor does not constantly supply energy to the heating element, but causes the control electronics to activate the heating element. As a result, the use of switches or smoke-absorbing sensors can serve to save energy compared to devices that do not employ these elements and may provide on-demand heating rather than constant heating.

For illustrative purposes, one method of using the shisha device described herein is provided below in chronological order. The vessel may be removed from the other components of the shisha device and filled with water. One or more of the natural fruit drinks, botanical ingredients, and herbal exudates may be added to the water for flavoring. The amount of liquid added should cover part of the conduit, but not above the filling level mark, which may be optionally present on the vessel. The vessel is then reassembled into the shisha device. A portion of the aerosol generating element may be removed or opened to allow the cartridge to be inserted into the receiver. The aerosol generating element is then reassembled or closed. The device may then be turned on. Turning on the apparatus can initiate a heating profile of the heating element to heat the aerosol-forming substrate to a temperature above the evaporation temperature of the aerosol-forming substrate but below the combustion temperature of the aerosol-forming substrate. The user may smoke with the mouthpiece as desired. The user can continue to use the device until the aerosol disappears and is delivered. In some embodiments, the device automatically shuts down when the usable aerosol-generating substrate of the cartridge is depleted. In some embodiments, the consumer may refill the device with an unused cartridge, for example, after receiving a signal from the device that the aerosol-forming substrate in the cartridge is depleted or nearly depleted. Once the unused cartridges are filled, the device can continue to be used. It is preferred that the shisha device can be turned off at any time by the consumer, for example by turning off the device.

The shisha device may have any suitable air management. In one embodiment, the smoke-sucking behavior from the user creates a suction effect that causes a low pressure inside the device, which causes outside air to flow through the device's air-suction port into the fresh air-suction port channel and into the receptacle. Air can then flow through the cartridge into the receptacle to carry the aerosol produced from the aerosol-forming substrate. The air containing the mixed aerosol then exits the aerosol outlet of the receiver and flows through the conduit to the liquid in the container. The aerosol then foams out of the liquid, enters the upper space above the level of the liquid in the vessel, and exits the upper space exit for delivery to the consumer through the hose and mouthpiece. .. The external air flow and the aerosol flow inside the shisha device may be driven by smoke absorption from the user.

Example 1: Cylindrical Cartridge The following are non-limiting examples showing the effects of various cartridge designs on the production of aerosols from aerosol-forming substrates placed within a shisha cartridge. Each cartridge includes a commercially available tobacco molasses 10g having a calculated volume of about 31.5cm ³ (Al-Fakher).

Three cartridge designs were tested. Each cartridge is cylindrical and is made of aluminum. The cartridge has a length of 55 mm and an inner diameter of 27 mm. One cartridge contains no thermal bridge has in the recess of the heatable surface area of about 52cm ² (S _H). Another cartridge includes a copper plate T-shaped having a thickness of 0.2 mm (Fig. 11a-d), which provides a total S _H of suffering from depression about 69cm ^2. Another cartridge further comprises a providing a S _H of about 90cm ² rests in the recess, the copper plate having a S-shaped cross-section with a thickness of 0.2 mm (see FIG. 12).

The cartridge was placed in communication with the conduit. A truncated cone-shaped nozzle made of high temperature epoxy resin with a 3 mm outlet orifice was incorporated into the conduit. The nozzle outlet orifice is approximately 55 mm from the cartridge outlet. The conduit extends below the liquid level in the vessel. Aerosols exiting the outlet communicating with the upper space above the liquid level in the vessel were collected.

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

The generated aerosols were collected using a total of 10 Cambridge pads whose weights were recorded before and after the shisha experience. The total duration of the experience corresponds to 105 smoke inhalations. To achieve the desired smoke absorption experience, four programmable dual syringe pumps (PDSPs) from Tolbert, Groningen, The Netherlands were used simultaneously to create the following smoke absorption regimen.
・ Smoke absorption volume: 530mL
・ Smoke absorption duration: 2600ms
・ Period between smoke absorption: 17 seconds

The experimental setup was arranged so that only two of the ten Cambridge pads would collect the aerosol generated at a given time point. After every 21 smoke inhalations, a check valve was used to ensure that the aerosol was distributed to the correct pair of Cambridge pads. As a result, it is possible to monitor aerosol formation as a function of time.

The evaporative mass of molasses was determined by comparing the weight of molasses before and after the shisha experience.

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

Results from various cartridge designs are shown in FIG. 13 and Table 1. In FIG. 13, the TAM per smoke absorption after the first 20 times of smoke absorption is shown. In Figure 13, the curve labeled (1), represents the results from coal-operated Shisha device, the curve labeled (2), represents a cartridge having a S _H of about 52cm ^2, labeled (3) is about It represents a cartridge having a S _H of 69cm ^2, the curve labeled (4) represents a cartridge having about 90cm ² S _H.

Tested cartridge Yes 1.5 cm ^-1 of the (S _H = 52cm for ² cartridge) ～3Cm ^-1 (for S _H = 90cm ^2), the ratio of S _H relative to the volume of the aerosol-forming substrate (tobacco molasses) bottom.

Charcoal actuated shisha used in these experiments, consume 3.5 g, having a S _H of 25 cm ^2. Since the heat transfer through convection much less than electrical shisha, only 2.8g was consumed for S _H = 52cm ^2. As a result, the total TAM collected for electroheated shisha is only ~ about 80% of the charcoal-operated shisha for this cartridge (1700 mg vs. 1370 mg). In particular, the aerosol mass produced, during the first 21 rounds of puff substantially less, with respect to 12.7 mg / puff acquired with charcoal actuated shisha, the cartridge S _H = 52cm ² 8.7mg / puffing TAM was collected. However, by increasing S _H to 90cm ^2, the results obtained by the electronic shisha has a value similar to the coal actuated shisha. In this case, molasses consumption increased to 3.9 g, TAM collected increased to 1850 mg, and TAM collected during the first smoke absorption increased to 12.0 mg / smoke absorption.

To demonstrate the design considerations to achieve the ratio of desired S _H relative to the volume of the aerosol-forming substrate, referring to Figure 14. In Figure 14, the lower trace shows the S _H calculated for cylinder having a volume of 31.5cm ³ of different diameters. Corresponding lengths are shown on the top x-axis. The calculated result is, in the case of not using the thermal bridge, to achieve S _H of 90cm ² indicates that it is necessary cartridge having a length of about 18cm. However, these lengths are not practical for many shisha devices.

Trace labeled D / 3 has the same dimensions as the lower trace has a cylindrical thermal bridge having a diameter equal to 1/3 of the diameter of the cartridge, shows the calculated S _H relative to the cylindrical. Trace labeled D / 2 has the same dimensions as the lower trace has a cylindrical thermal bridge having a diameter equal to 1/2 of the diameter of the cartridge, shows the calculated S _H relative to the cylindrical. As shown, thermal bridge is to provide a cartridge having a more desirable size rapidly increased S _H. For example, the cartridge has a length of less than 10 cm, may have S _H of 90cm ^2.

Example 2: Cone-shaped cartridge

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

The cartridge is cylindrical and is made of aluminum. The cylindrical cartridge has a length of 41.25 mm and an inner diameter of 27 mm (C27). The truncated cone-shaped cartridges have a length of 41.25 mm and an upper inner diameter of 27 mm, respectively. The lower inner diameter of the truncated cone-shaped cartridge is 22 mm (LD22), 18 mm (LD18), and 14 mm (LD14). The top and bottom of each cartridge contains 19 holes, each with a diameter of 2 mm.

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

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

The time to reach 80 ° C. may be directly related to the time of the first smoke absorption. Therefore, the cylindrical cartridge (C27) may allow for more rapid initial heating and allow for faster first smoke absorption. However, the long time associated with the truncated cone cartridges (LD22, LD18, and LD14) more closely mimics the time to first smoke absorption associated with conventional charcoal-based shisha devices, and therefore. Certain conventional aspects of these conventional devices can be maintained.

In another experiment, C27, LD22, and LD18 cartridges containing 10 g of molasses were heated and the total aerosol mass and the mass of evaporated molasses were measured. For the C27 cartridge, the LD22 cartridge was heated for an additional 30 seconds prior to the test, and the LD18 cartridge was heated for an additional 60 seconds based on the results shown in Table 2 above.

The mass of molasses evaporated is shown in FIG. 15, and the total mass of aerosol produced is shown in FIG. As shown in FIG. 16, the maximum total aerosol mass was observed with the LD22 cartridge. As shown in FIG. 15, the amount of molasses evaporated increased as the diameter of the cartridge decreased.

In another experiment, total aerosol mass and evaporated molasses were measured for C27 cartridges containing 10 g molasses and for LD22 cartridges containing 10 g, 8 g, and 6 g molasses. For the C27 cartridge, the LD22 cartridge was heated for an additional 30 seconds prior to the test based on the results shown in Table 2 above.

The mass of molasses evaporated is shown in FIG. 17, and the total mass of aerosol produced is shown in FIG. As shown in FIG. 18, the total aerosol mass is similar between LD22 cartridges containing 10 g and 8 g molasses, suggesting that less molasses can be used. In addition, the LD22 cartridge containing 6 g molasses exhibited an increase in total aerosol mass for the first 60 smoke inhalations compared to the C27 cartridge containing 10 g molasses, and the shape of the cartridge was the total aerosol production and molasses that could be used. It suggests that it can have a substantial effect on the amount of.
