Description

The present invention relates to electrical aerosol generating systems, in particular to electrical aerosol generating systems having an aerosol generating device and a case for housing the aerosol generating device.

Known electrical aerosol generating systems generally comprise an aerosol generating device having a nebulizer and an electrical power source for supplying power to the nebulizer. The atomizer may be an electrical heater. In addition, known systems generally comprise an aerosol-forming substrate that is placed in a device and sprayed with a nebulizer to release volatile compounds in the aerosol-forming substrate that form an aerosol for inhalation by the user. Some known systems also include a case for housing the aerosol generating device when not in use. Cases are known in various systems to provide various functions such as protecting the device when not in use, recharging the battery of the device, and, in some cases where the aerosol-forming substrate is a liquid aerosol-forming substrate, refilling the device with the liquid aerosol-forming substrate.

In some known aerosol generating systems, the aerosol generating device is configured to receive an aerosol generating article containing a solid aerosol generating substrate, such as an assembled corrugated tobacco sheet. In these systems, the device typically comprises a heating blade nebulizer that is configured to penetrate a solid aerosol-forming substrate upon placement of the article in the device and to heat the aerosol-forming substrate from the inside. When the product is removed from the device, a small amount of aerosol-forming substrate residue may remain on the heating blade. It is known to clean the heating blade of residues by pyrolysis, where the device is configured to heat the heating blade to a high temperature above the operating temperature to which the heating blade heats the aerosol-forming substrate to remove residues from the heating blade by thermal decomposition. In systems containing a case, it may be preferable to perform the pyrolysis cycle while the device is placed in the case. In general, the pyrolysis cycle is preferred when the aerosol generating device is in a case, since the case is able to provide additional protection to the user from the heating blade when it is heated to the high temperature required to thermally decompose the residue.

It would be desirable to provide such a case for an aerosol generating device that collects information about the device. It would be particularly desirable to provide such a case for an aerosol generating device that would track the use of the device. It would also be desirable to provide a case that enhances the user experience of the device and the aerosol generating system.

According to a first aspect of the present invention, there is provided a case for an aerosol generating device, comprising: a case; a holder for accommodating a part of the aerosol generating device, the holder being movably connected to the housing and movable relative to the housing between an open position for accommodating the aerosol generating device and a closed position for storing the aerosol generating device; and a holder position detector configured to determine whether the holder is in an open position or in a closed position.

By equipping the case with a holder position detector, it is possible to determine the position of the holder relative to the casing. This provides the advantage of being able to track the use of the aerosol generating device with the case. For example, movement of the holder from the closed position to the open position may indicate that the user has opened the case to remove the device from the holder, and movement of the holder from the open position to the closed position may indicate that the user has ended the session and returned the device to the case for storage between sessions. Thus, keeping track of the position of the device holder makes it possible to display the number of times the device has been taken out of the case for use.

In the context of this document, the term "open position" is used to describe the positions or orientations of the holder relative to the casing, in which the aerosol generating device can be placed by the holder and removed from the holder.

The electrical aerosol generating device may include an atomizer, such as an electrical heater, for heating the aerosol-forming substrate to form an aerosol.

In the context of this document, the term "aerosol-generating article" refers to an article containing an aerosol-forming substrate capable of releasing volatile compounds that can form an aerosol.

This provides the advantage of being able to track the use of the aerosol generating device more accurately than counting the number of times the holder moves between open and closed positions.

In some preferred embodiments, the case includes means for recharging the power source of the aerosol generating device placed in the holder. In these preferred embodiments, the case may be referred to as a charging case.

In these preferred embodiments, the case contains a battery. The power source may be any suitable types of electrical power source.

In other embodiments, the data transfer may be two-way, namely from the aerosol generating device to the case and from the case to the aerosol generating device. The electrical connector may have at least one electrical contact configured to transmit electrical power. The electrical connector may have at least one electrical contact configured to transmit an electrical signal containing data.

The case may further contain a power supply control circuit. The power supply control circuit may be configured to control the supply of power from the case power source to the electrical connector.

In some embodiments, the power supply control circuit may be configured to monitor the charge level of the power source of the aerosol generating device placed in the holder. The power supply control circuit may be configured to monitor the level of charge of the power supply of the aerosol generating device by monitoring one or more of the voltage and current supplied to the aerosol generating device from the power supply of the case.

The power supply control circuit may be configured to initiate a charging cycle if it is determined that the aerosol generating device is placed in the holder and the holder is in the closed position. The charging cycle may include applying power from the power supply of the case to the power supply of the aerosol generating device until the power supply of the aerosol generating device is fully charged. If it is determined by the power supply control circuit that the power supply of the aerosol generating device is fully charged, then the power supply control circuit may complete the charging cycle by preventing power from being supplied from the power supply of the case to the power supply of the aerosol generating product.

The case may further comprise an electrical connector for connecting the case's power source to an external power source for recharging the case's power source. The case may contain any suitable electrical connector for connecting the power supply of the case to an external power source.

The signal may be any suitable type of signal. The signal may contain information or data. The signal may contain information or data related to the use of the device. The signal may contain instructions for controlling the aerosol generating device.

Preferably, the signal is applied through a wired connection between the case and the aerosol generating device. Particularly preferably, the signal is applied through the electrical connectors of the case and the device when these electrical connectors are electrically connected. However, in some embodiments, the signal may be transmitted over a wireless connection between the case and the aerosol generating device. In these embodiments, the case includes a transmitter for transmitting a signal to an aerosol generating device, and the aerosol generating device includes a receiver for receiving said signal.

In some preferred embodiments, the case is configured to house an aerosol generating device comprising: a heater configured to heat the aerosol generating substrate; power supply; and a control circuit configured to control the power supply from the power source to the heater. In these preferred embodiments, the control circuitry of the aerosol generating device may be configured to perform a cleaning cycle when the aerosol generating device is placed in the case. The cleaning cycle may include applying power to the heater, typically higher power than during normal operation, to raise the temperature of the heater to a temperature sufficient to thermally decompose any remaining aerosol-forming substrate on the heater. Such a purification cycle may also be referred to as a pyrolysis cycle. The heater may be heated to any suitable temperature during the cleaning cycle to thermally decompose residual aerosol-forming substrate on the heater. For example, the heater may be heated to a temperature of about 400 degrees Celsius to about 700 degrees Celsius. In some preferred embodiments, organic materials deposited on the heating element may be thermally released by raising the temperature of the heater to about 430 degrees Celsius or higher. For example, the temperature may be raised to 475 degrees Celsius or higher, or 550 degrees Celsius or higher. The temperature of the heater may be raised to higher temperatures, such as 600 degrees Celsius or more, or 800 degrees Celsius or more.

The cleaning cycle may be performed for any suitable amount of time. Preferably, the heater is maintained at a high temperature for a period of time necessary to effect thermal release of the organic compounds. Typically, the cleaning cycle is performed for a predetermined period of time. For example, said predetermined time period may be from about 10 seconds to about 7 minutes, from about 30 seconds to about 5 minutes, or from about 2 minutes to about 4 minutes. In some preferred embodiments, the heater may be maintained at a high temperature in the cleaning cycle for at least 5 seconds. Preferably, the heater is maintained at a high temperature in the cleaning cycle for about 5 seconds to about 60 seconds, such as from about 10 seconds to about 30 seconds.

Preferably, the aerosol generating device comprises an electrical connector. The electrical connector may be complementary to the electrical connector of the case. The electrical connector of the aerosol generating device may be configured to be electrically connected to the electrical connector of the case when the aerosol generating device is placed in the holder. The electrical connector of the aerosol generating device may be configured to electrically connect to the electrical connector of the case when the aerosol generating device is placed in the holder and the holder is in the closed position. The power supply control circuit in the case may be configured to supply power to the power supply of the aerosol generating device by electrically connecting said electrical connectors. The holder position detector circuit in the case can be configured to transmit a signal to the control circuit of the aerosol generating device by electrically connecting said electrical connectors.

In some preferred embodiments, the holder-in-case position detector circuit may be configured to send a signal to the aerosol generating device to initiate a cleaning cycle. Such a signal is also referred to herein as a "clear signal". The case holder position detector circuitry may be configured to send a purge signal to the aerosol generating device to initiate a purge cycle if the holder position detector indicates that the aerosol generating device is placed in the holder and the holder is in the closed position. In these embodiments, the control circuit of the aerosol generating device is configured to perform a cleaning cycle upon receiving a signal from the power supply control circuit in the case. This provides the advantage of being able to hinder or prevent the aerosol generating device from performing a cleaning cycle while the aerosol generating device is outside the case. Performing a cleaning cycle only if the aerosol generating device is housed in a case allows for further protection of the user from contact with the heater of the device when the heater is heated to the high temperature required for the cleaning cycle.

In some embodiments, the aerosol generating device control circuit is configured to supply power from the aerosol generating device power supply to the heater during the cleaning cycle. However, in some embodiments, the control circuitry of the aerosol generating device is configured to supply power from an electrical connector of the aerosol generating device to the heater during a cleaning cycle. This allows power to be supplied from the power supply of the case directly to the heater of the aerosol generating device during the cleaning cycle. In this way, it is possible to supply a higher power to the heater than is possible when supplied from the power source of the aerosol generating device.

In particularly preferred embodiments, the holder position detector circuitry is configured to increase the count each time it is determined that the aerosol generating device is placed in the holder and the holder is in the closed position. The holder position detector circuit is further configured to compare the count result with one or more threshold values and transmit a cleaning signal to the aerosol generating device if the count result is equal to or greater than one or more threshold values. Said one or more threshold values may be predetermined values that are stored in the memory of the holder position detector circuit. Said one or more threshold values may be setpoints that indicate the maximum number of times the aerosol generating device is to be used between cleaning cycles. The first threshold value may indicate the first optimal number of times the device is used between cleaning cycles. The first threshold may be any suitable value, such as 3 to 30, 5 to 25, 7 to 20, or one of 10, 11, 12, 13, 14, or 15. A second threshold greater than the first threshold, can specify the maximum number of times the device should be used between cleaning cycles. The second threshold value may be any suitable value such as 5 to 40, 10 to 35, 15 to 30, or one of 20, 21, 22, 23, 24 and 25.

The holder position detector circuit may be configured to reset the count to zero when a purge signal is applied to the aerosol generating device. Resetting the count to zero when a purge signal is applied to the aerosol generating device may indicate that the aerosol generating device has already gone through a purge cycle.

In some embodiments, the holder position detector circuitry is configured to send a deactivation signal to the aerosol generating device if it is determined that the count is equal to or greater than one or more threshold values. If a deactivation signal is received by the control circuit of the aerosol generating device, then the control circuit has the ability to prevent power being supplied to the heater until the purge signal is received. This makes it possible to ensure that the aerosol generating device is not used again until the cleaning cycle is performed. The holder position detector circuit may be configured to transmit a deactivation signal at any suitable time. Typically, the holder position detector circuitry is configured to transmit a deactivation signal before the start of a charge cycle.

The holder position detector circuit may be configured to transmit a cleaning signal to the aerosol generating device at any suitable time. For example, the holder position detector circuit may be configured to transmit a cleaning signal to the aerosol generating device after the completion of a charging cycle of the aerosol generating device. This makes it possible to ensure that the power source of the aerosol generating device will have sufficient charge to carry out the cleaning cycle. It also makes it possible to prioritize charging the power source of the aerosol generating device over cleaning the aerosol generating device so as to allow the device to be charged to a level sufficient for cleaning. By prioritizing charging the power source of the aerosol generating device over cleaning, the user has the option, if necessary, to remove the device from the case before starting the cleaning cycle.

The holder position detector circuit is preferably configured to prevent transmission of a purge signal to the aerosol generating device if the holder is determined to be in an open position. This provides the ability to help further protect the user from contact with the heater of the device when the heater is heated to the high temperature required for the cleaning cycle.

In some embodiments, the holder position detector circuitry may also be configured to prevent a purge signal from being transmitted to the aerosol generating device until an external power source is connected to the case power source. This makes it possible to ensure that the power supply of the case will have sufficient charge to supply power to the aerosol generating device during the entire cleaning cycle. In some embodiments, the power supply control circuitry in the case may also be configured to supply power directly from an external power source to the aerosol generating device via an electrical connector.

In particularly preferred embodiments, the holder position detector circuit is configured to start a cleaning cycle in the aerosol generating device if it is determined that the aerosol generating device is in the holder, the holder is in the closed position, and the count is equal to or greater than the first threshold but less than the second threshold. values. In some embodiments, the holder position detector circuitry requires an additional condition to initiate a cleaning cycle if the case is required to be connected to an external power source. Preferably, the holder position detector circuitry is configured to transmit a cleaning signal to the aerosol generating device after completion of the charge cycle.

In particularly preferred embodiments, the holder position detector circuit is further configured to send a deactivation signal to the aerosol generating device if it is determined that the count is greater than or equal to the second threshold. If a deactivation signal is received by the control circuit of the aerosol generating device, the control circuit is able to prevent power being supplied to the heater until the purge signal is received. The holder position detector circuit is configured to transmit a deactivation signal before a charge cycle is initiated. The control circuit is configured to transmit a cleaning signal to the aerosol generating device after completion of the charging cycle. This is to help ensure that the aerosol generating device is not used excessively between cleaning cycles, whereby residues on the heater will adversely affect aerosol generation and composition. If it is determined that the count result is equal to or greater than the second threshold value, the number of conditions for transmitting the clear signal can be reduced. For example, it may not be necessary for the case to be connected to an external power source prior to transmitting the clear signal. The holder position detector circuit may only require that the power supply of the case is above a minimum charge level, the aerosol generating device is placed in the holder, and the holder is in the closed position.

The case may be of any suitable size and shape to accommodate the aerosol generating device. Usually the case is portable. In other words, the case is of a suitable size and shape to be carried by the user. Preferably, the case is a hand held case.

The term "magnetic material" is used herein to describe a material capable of interacting with a magnetic field, including both paramagnetic and ferromagnetic materials. The magnetizable material may be a paramagnetic material such that it only remains magnetized in the presence of an external magnetic field. Alternatively, the magnetizable material may be a material that becomes magnetized in the presence of an external magnetic field and remains magnetized after the external field is removed (eg, a ferromagnetic material).

On FIG. 1-5 show schematic illustrations of a case 101 according to a known electrical aerosol generating system. A known electrical aerosol generating system includes a case 101, an aerosol generating device 120, and an aerosol generating article 130.

The case 101 includes a casing 102 and a holder 106.

The case 102 accommodates a power source 103 in the form of a lithium ion battery 103 and an electrical circuit 104. The case 102 also defines a cavity 105 that is shaped and sized to accommodate a portion of the holder 106 and the aerosol generating device 120 when the aerosol generating device 120 is placed in the holder. 106.

Case 101 is configured to accommodate aerosol generating device 120.

The aerosol generating device 120 is essentially circular and has the general dimensions of a conventional cigar. The length of device 120 is substantially equal to the length of cavity 105, and the diameter of device 120 is somewhat smaller than the diameter of cavity 105 so that device 120 fits snugly into cavity 105. Aerosol generating device 120 includes an open cavity 121 at its proximal end to accommodate aerosol generating article 130 The aerosol-generating device 120 further comprises an electrical heater 122 disposed in the cavity 121 for heating at least a portion of the aerosol-generating article 130 while the aerosol-generating article 130 is placed in the cavity 121. supplying power to the heater 122 together with a control circuit 124 for controlling the supply of power from the power source 123 to the heater 122. The aerosol generating device 120 also includes an electrical connection portion 125 which is located on a distal end surface opposite the proximal end and is configured to receiving power from an external power source to recharge the power supply 123 .

The aerosol-generating article 130 comprises an aerosol-generating substrate (not shown) in the form of an assembled corrugated tobacco sheet and a filter (not shown) located end-to-end with the aerosol-generating substrate in the form of a rod. The aerosol-generating article 130 has a diameter substantially equal to the diameter of the cavity 121 of the device 120 and a length greater than the length of the cavity 121, so that when the article 130 is placed in the cavity 121 of the device 120, the filter extends beyond the cavity 121 and the user can exercise on it. puff like a regular cigarette.

In use, the user inserts the article 130 into the cavity 121 of the device 120 and turns on the device 120 to actuate the electrical heater 122. The electrical heater 122 heats the aerosol-forming substrate of the article 130 so that volatile compounds of the aerosol-forming substrate are released and condense to form an aerosol. The user puffs on the filter of article 130 to inhale the aerosol generated from the heated aerosol-forming substrate.

After use, product 130 can be removed from device 120 for disposal, and device 120 can be placed in case 101 for storage and to charge the battery of device 120.

The casing 102 of the case 101 generally forms an open rectangular box having side walls defining five sides of the box and an opening in the sixth side of the box. The opening defines the open end of cavity 105 and extends substantially the length and width of one side of housing 102.

The holder 106 of the casing 101 includes an outer wall 107 and an inner wall 108.

The outer wall 107 is elongated and has a length substantially equal to the length of the casing 102. The length of the outer wall 107 determines the length of the holder 106. The outer wall 107 is shaped and sized to cover the opening of the casing 102. Thus, the outer wall 107 is shaped and dimensions in the same way as the sixth side wall of the casing 102.

Inner wall 108 forms a substantially circular tube defining a generally circular inner passage 109 that extends along the length of inner wall 108. Passage 109 is open at one end and closed at the other end opposite the open end. The passage 109 has a cross-section along its length that is substantially identical to that of the aerosol generating device, with the diameter of the inner passage 109 being slightly larger than that of the aerosol generating device so that the aerosol generating device can be retractably held in the inner passage 109 of the holder 106.

The tubular inner wall 108 of the holder 106 is integral with the outer wall 107. It should be understood that in some embodiments, the inner wall 108 may not be integral with the outer wall 107, and instead it may be attached to the outer wall 108 using any suitable fasteners. The tubular inner wall 108 is positioned such that its longitudinal axis is substantially aligned with the longitudinal axis of the outer wall 108. the first end towards the second end. The length of the inner wall 108 is less than the length of the outer wall 107. Thus, the inner wall 108 does not extend along the entire length of the outer wall 107. The portion of the holder 106 at the second end does not include the inner wall 108. In other words, the inner wall 108 does not extend along the length of the holder. 106 from the first end to the second end. The length of the inner wall 108 is approximately 70% of the length of the outer wall 107. Thus, a space or gap 110 is provided between the end of the inner wall 108 near the second end of the holder 106 and the end of the outer wall 107 at the second end of the holder 106.

The holder 106 is pivotally connected 111 to the casing at the first end. In particular, the outer wall 107 is rotatably connected to the housing 102 at one end of the opening of the cavity 105. The swivel 111 allows the holder 106 to rotate or move relative to the housing 102 between an open position, in which the open end of the passage 109 near the second end of the holder 106 is open, and closed a position in which the open end of the passage 109 is closed by the casing 102 and the opening of the casing 102 is covered by the outer wall 107 of the holder 106.

The inner wall 108 of the holder 106 is placed in the cavity 105 of the casing 102 when the holder 106 is rotated to the closed position. When the aerosol generating device is placed in the inner passage 109 of the holder 106 and the holder is rotated to the closed position, the aerosol generating device is enclosed in the cavity 105 because it is surrounded or closed by the walls of the casing 102 and the outer wall 107 of the holder 106. In this position, the possibility of essentially protecting aerosol generating device with the case while the holder is in the closed position.

An electrical connector 113 is located at the closed end of the inner passageway 109 to cooperate with a complementary electrical connector on the far end of the aerosol generating device 120 when the aerosol generating device 120 is placed in the inner passage 109. The electrical connector may be any suitable type of electrical connector. . The electrical connection part is electrically connected to the electrical circuit 104 in the case 102 of the case 101 by means of a flexible printed circuit (not shown), which allows the electrical connection part to move with the holder without damaging the electrical connection.

On FIG. 2 and 3 show schematic illustrations of a case 101 in which the holder 106 rotates around the pivot 111 relative to the casing 102 between a closed position and an open position, respectively.

The holder 106 is rotatable relative to the housing 102 between two predetermined positions: a closed position and an open position. Holder 106 is rotatable in a first direction to rotate holder 106 relative to housing 102 from an open position to a closed position. In this embodiment, the outer wall 107 of the holder 106 overlaps with the shroud 102 at the second end so that the outer wall 107 contacts the shroud 102 when the holder 106 is in the closed position to prevent the holder 106 from rotating further in the first direction beyond the closed position. The holder 106 is also rotatable in a second direction opposite the first direction to rotate the holder 106 relative to the housing 102 from a closed position to an open position. The cavity 105 of the housing 102 includes a stopper (not shown) that is configured to contact the inner wall 108 of the holder 106 when the holder 106 is in the open position to prevent the holder 106 from rotating in a second direction beyond the open position.

On FIG. 3 shows holder 106 in the open position. In this embodiment, in the open position, the opening 112 between the housing 102 and the first end of the outer wall 107 of the holder 106 has a width or diameter approximately twice the width or diameter of the aerosol generating device. It should be understood that in some embodiments, the implementation of the holder can be rotated relative to the casing at different angles, which provides holes between the casing and the first end of the outer wall of the holder, having different widths.

The wide opening 112 and the gap 110 between the second end of the inner wall 108 and the second end of the outer wall 107 allow the aerosol generating device to be inserted into the holder 106 at a wide range of angles. In particular, the gap 110 allows the aerosol generating device to contact the outer wall 107 when the aerosol generating device is inserted into the holder 106. This allows the portion of the outer wall 107 without the inner wall 108 at the second end of the holder 106 to be used as a guide for aligning the aerosol generating device, with a passage 109 of the tubular inner wall 108. This allows further assistance in inserting the aerosol generating device 120 into the holder 106.

On FIG. 4 and 5 show an aerosol generating device 120 releasably held in holder 106 with holder 106 in the closed position and in the open position, respectively.

On FIG. 4 shows the aerosol generating device 120 placed in the holder 106 with the holder 106 in the open position. As shown in FIG. 4, a gap 110 between the second end of the inner wall 108 and the second end of the outer wall 107 exposes a portion of the aerosol generating device 120 at the proximal end of the device 120. This exposed portion at the proximal end of the device 120 can be accessed and gripped by the user to remove the device 120 from the holder. 106. Accordingly, the holder 106 does not require a lifting mechanism to lift the device 120 from the holder 106. This allows the holder 106 to be cost-saving and simpler in design compared to holders that include lifting mechanisms for removing the devices.

On FIG. 5 shows the aerosol generating device 120 held in the holder 106 when the holder 106 is in the closed position. The aerosol generating device 120 is completely enclosed in the cavity 105 of the housing 102, being surrounded by the housing 102 and the outer wall 107 of the holder 106. In this configuration, the aerosol generating device 120 is substantially protected by the case 101.

At the closed end of passageway 109, an electrical connector 113 is provided for electrical connection to electrical connector 125 of aerosol generating device 120 to connect battery 103 of case 101 to battery 123 of device 120 when device 120 is placed in holder 106 and holder 106 is in the closed position. Accordingly, the case 101 is configured to supply power to the aerosol generating device 120 to charge the aerosol generating device 120 when the aerosol generating device is in the holder 106 and the holder 106 is in the closed position.

On FIG. 6 shows a schematic view of a case according to the first embodiment of the present invention.

On FIG. 6 shows a case 201 according to the first embodiment of the present invention. Case 201 is substantially similar to case 101 described above with reference to FIG. 1-5. The case 201 includes a casing 202 and a holder 206. The casing 202 houses a battery 203, a circuit 204, and a cavity 205 for receiving the holder 206. The holder 206 includes an outer wall 207 and a tubular inner wall 208 defining a passage 209 having a closed end at the first end of the holder 206 and open end at the second end of the holder 206. The holder 206 is rotatably connected to the housing 202 at the first end so that the holder 206 can be rotated between an open position in which the outer wall 207 at the second end of the holder 206 is spaced from the housing 202 and a closed position. , in which the outer wall 207 covers the opening of the cavity 205 and is in contact with the casing 202 at the second end.

The inner wall 208 is generally circular and contains a generally circular inner passage 209. The inner wall 208 extends generally along the outer wall 207 from the first end towards the second end.
