Some terms may be used without further explanation; in such cases, their meaning will be described in detail in the description of the invention. Therefore, the terms used in this invention are not simply names of terms, but rather the meanings that those terms possess. This must be defined based on the overall content of the present invention.

[0031] In the following, with reference to the attached drawings, embodiments of the present invention will be described, and the technical aspects to which the present invention belongs This will be explained in detail so that it can be easily implemented by anyone skilled in the art in the field. However, the present invention can also be embodied in various different forms, including the embodiments described herein. It is not limited to that.

[0032] Figure 1 is a flowchart for determining whether an aerosol generation device malfunctions.

[0033] Referring to step 110, the control unit can determine the operating state of the aerosol generator. Yes, it is possible. The operating state of the aerosol generating device can also be classified into a heated state and a non-heated state.

[0034] The control unit determines the operating state by controlling the flow through the first circuit section that controls the heater. The current can be monitored. Based on the monitoring results, the control unit performs a first If the control unit detects that a current exceeding a predetermined value is flowing through the circuit, it will heat the operating state. The state can be determined, and when it is detected that a current less than a predetermined value is flowing through the first circuit section, In this case, the operating state can be determined to be a non-heated state.

[0035] The non-heating state is also divided into a charging state and a standby state. The second circuit section is the charging terminal. When receiving current from an external charging device via the aerosol, the control unit senses this and aerosol The operating state of the generating device can be determined as a charging state. The second circuit unit, via the charging terminal If no current is received from the external charging device, the control unit will sense this and generate an aerosol. The operating state of the device can be determined to be a standby state.

[0036] Referring to step 120, the control unit, based on the operating status of the aerosol generator, performs the first It can communicate with the path section or the second circuit section.

[0037] For example, the control unit, based on the operating state of the aerosol generator, in the heated state, It can communicate with the first circuit section, and in a non-heating state, it can communicate with the second circuit section.

[0038] The control unit inputs data to the first circuit unit or the second circuit unit, or the first circuit unit Alternatively, by receiving data from the second circuit section, the first circuit section or the second circuit section and It can communicate.

[0039] Based on the operating state of the aerosol generator, when the control unit is in a heated state, the first circuit unit and The meaning of communicating, and communicating with the second circuit section when not heated, is that the control unit operates Depending on the status, the primary communication target is set to either the first circuit section or the second circuit section, and the surrounding area This could mean that the system will communicate with the circuit section designated as the primary communication target.

[0040] In one embodiment, when the aerosol generator is operating in a heated state, the control unit is It can communicate with a first circuit unit and receive first current amount data flowing through the first circuit unit. In another embodiment, when the aerosol generating device operates in a non-heated state, The control unit communicates with the second circuit unit and receives the second current amount data flowing through the second circuit unit. It is possible.

[0041] In yet another embodiment, in the heated state, the control unit inputs first data to the first circuit unit. Communication is performed by reading the second data from the first circuit section after a predetermined time has elapsed. The control unit can perform the following based on the first data and the second data: The condition can be determined. Furthermore, the first circuit unit can also determine whether an abnormality has occurred in the control unit. This is possible. This will be explained in more detail in Figure 10.

[0042] Referring to step 130, the control unit, based on the communication results, determines the operating status of the aerosol generator. It is possible to determine how abnormalities occur depending on the state.

[0043] An aerosol generator malfunction refers to a problem with the hardware configuration within the aerosol generator. This could mean that at least one configuration is not working or is malfunctioning.

[0044] For example, the first circuit section heats the heater according to a pre-designed temperature profile. If this is not possible, it also means that an abnormality has occurred in the first circuit section. Another example is when the charging device is connected If the battery is not charged despite being connected, an abnormality is detected in the second circuit. This also resulted in the situation.

[0045] The determination of whether an aerosol generator malfunctions is made based on the data received by the control unit and each This can also be accomplished by comparing it with a critical range already specified based on the operating state. In one embodiment, when the control unit determines that the operating state of the aerosol generator is a heating state, The control unit receives the first current data from the first circuit unit and specifies that it is suitable for heater heating. By comparing it with the first critical range, the abnormality of the aerosol generator can be determined. It can be determined.

[0046] In another embodiment, the control unit determines the operating state of the aerosol generator to be a non-heating state. In this case, the control unit receives the second current amount data from the second circuit unit and determines the charging state or standby state. By comparing it with the second critical range specified to suit the conditions, the aerosol generator It is possible to determine whether an abnormality has occurred.

[0047] The embodiment described in Figure 1 can be summarized as follows:

[0048] If the control unit determines that a current exceeding a predetermined value flows through the first circuit section, the aerosol generating unit The state of the device can be determined to be a heated state. In this heated state, the control unit determines the main communication target From the first circuit section, it is possible to receive the first current amount data flowing through the first circuit section. The control unit then determines, based on the first current data, whether an abnormality has occurred in the first circuit section. It is possible to make a decision.

[0049] If the control unit determines that a current less than a predetermined value flows through the first circuit section, the aerosol generating unit The state can be determined to be a non-heated state. In this non-heated state, the control unit communicates The second circuit section, which is the target, can receive the second current amount data flowing through the second circuit section. The control unit then determines, based on the second current data, whether an abnormality has occurred in the second circuit section. It can be determined.

[0050] Figure 2 is a schematic conceptual diagram of an aerosol generation device.

[0051] Referring to Figure 2, the aerosol generator 100 has the following hardware configuration: control unit 1 01, First circuit section 102, Second circuit section 103, Battery 104, Heater 105, Temperature sensor It also includes the 106 and charging terminal 107. However, the above configuration is limited This means that it is not limited to, and may also include other necessary components. Any ordinary engineer in that technical field should be able to understand it. This configuration is not limited to the arrangement shown in Figure 2, but can also be used in other types of structures.

[0052] The charging terminal 107 responds when connected to an external charging device and receives from the external charging device. The current is applied to the second circuit section 103. The applied current controls the second circuit section 103. This allows the current to flow to the battery 104, which can then be charged.

[0053] On the other hand, the charging device does not use a wired charging method or a wireless charging method. All of these can be used. This wired charging method is a 5-pin terminal, an 8-pin terminal or USB ( It can utilize the Universal Serial Bus terminal system, and this wireless charging method utilizes a magnetic field. By utilizing inductive coupling, capacitive coupling using an electric field, and high-frequency radiation methods... This is possible. However, the charging device is not limited to the examples given above. The fact that other forms of charging devices are also included is typical in the art. If you are an engineer, you should be able to understand this.

[0054] The battery 104 supplies the power necessary for the aerosol generator 100 to operate. Battery 104 is both a rechargeable battery and a single-use battery. For example Battery 104 is also a lithium polymer (LiPoly) battery, but it is controlled It is not limited.

[0055] Furthermore, the battery 104 is electrically connected to the second circuit section 103, and the second circuit section 103 Charging and discharging are controlled accordingly. For example, the current applied via the charging terminal 107 is The battery is charged by the current flowing to the battery 104 via the second circuit section 103. Furthermore, the second circuit unit 103 controls the electrical energy stored in the battery 104. The second circuit section 103 is used to power the control unit 101 and the first circuit section 102, and aerozo It can supply current to other hardware components within the energy generator 100.

[0056] Furthermore, the aerosol generator 100 also includes a temperature sensor 106. The 106 measures the temperature of the heater 105 and transmits the temperature data to the control unit 101. The unit 101 then takes into consideration the received temperature data and adjusts the aerosol generator 10 It is possible to determine whether an abnormal occurrence of 0 has occurred.

[0057] As described above, the second circuit section 103 is electrically connected to the battery 104, and the battery 1 It can control the charging and discharging of O4.

[0058] After the charging terminal 107 and the external charging device are connected, the second circuit section 103 connects to the charging terminal 10 Current can be received from 7. The second circuit section 103 receives current from the charging terminal 107. In this case, the aerosol generator can operate in a charged state, and the second circuit section 1 03 supplies the current received from the charging terminal 107 to the battery 104, The TEL104 can be charged.

[0059] If the charging terminal 107 is not connected to an external charging device, the aerosol generator enters standby mode. It can operate in a normal state or a heated state, and the second circuit section 103 is connected to the battery 104 Receiving current from the aerosol generator 100, the movement of other hardware components installed within the aerosol generator 100 The current required for operation can be supplied. At this time, the battery 104 discharges. Figure 2 As shown in the figure, the second circuit section 103 supplies power to the control section 101 and the first circuit section 102. It can supply flow.

[0060] Specifically, when the aerosol generator 100 is in a heated state, the second circuit section 103, Battery 104 The stored electrical energy is discharged, and current flows to the control unit 101 and the first circuit unit 102. It is possible.

[0061] When the aerosol generator 100 is in standby mode, the second circuit unit 103 operates the battery 10 The electrical energy stored in 4 is discharged, and the control unit 101 is instructed to maintain the standby state. The current can be limited to the necessary amount. At the same time, to prevent the heater 105 from overheating. Therefore, current can be prevented from flowing through the first circuit section 102.

[0062] When the aerosol generator 100 is in a charging state, the second circuit unit 103 operates the battery 10 In order for 4 to be charged, the current received via the charging terminal 107 is supplied to the battery 10 It flows to 4. In this way, the second circuit section 103 receives the current from the charging terminal 107. The amount and direction of the current can be controlled so that it flows through the TERI 104. In this way, the second circuit section 103 is configured such that the battery 104 can be charged when the charging state is reached. The current flow can be controlled, and in the heated state and standby state, the battery 10 From step 4, it is possible to control the flow of current through each component of the aerosol generator 100. .

[0063] The second circuit section 103 receives power from the electrically connected charging terminal 107 via an external charging device. Current can be supplied. The control unit 101 can receive current from an external charging device when the second circuit unit 103 receives current from an external charging device. Upon sensing that a supply is being supplied, the operating state of the aerosol generator is determined to be either charging or standby. It can be determined.

[0064] In one embodiment, the second circuit section 103 also includes a number of switches. Receiving control signals from 101, or controlling the on / off state of multiple switches. This allows control of the amount of current for charging or discharging. In one embodiment, The second circuit section 103 includes at least one processor and a memory module for storing computer code. It also includes . The computer code is performed by at least one processor If executed, the function of the second circuit section 103 (for example, switching multiple switches, itself) We will also consider canceling it.

[0065] The first circuit section 102 receives the current output from the battery via the second circuit section 103. It can be operated by controlling the heater 105 from the control unit 101. A signal is input to control the heater 105, and current is supplied to the heater 105. Control the temperature.

[0066] For example, the first circuit section 102 may also include multiple switches. It receives control signals from the control unit 101 and controls the on / off state of multiple switches. This allows the current supplied to the heater 105 to be controlled. The first circuit section 102 includes at least one processor and stores computer code. It also includes memory. The computer code is configured on at least one processor. Therefore, if executed, the function of the first circuit section 102 (for example, switching of multiple switches, The first circuit unit 102 will perform (cancellation of the operation, data modification). Even if it is subordinate, it can actively control its own functions, just like the control unit 101. It is also a component that can do so. As a result, the first circuit section 102 actively operates the heater 105. It can be precisely controlled. In the heated state, the first circuit section 102 uses a heater to provide air. It can transmit appropriate control signals for heating rosol-forming materials.

[0067] Furthermore, if an abnormality occurs in the control unit 101, the first circuit unit 102 will shut down its own operation. It can be stopped. For example, the current flowing through the first circuit section 102 can be stopped if the first circuit section 102 This can also be accomplished by a method of self-interruption. The first circuit unit 102 automatically performs its own operation The system is designed to automatically cancel operations, and even if an abnormality occurs in the control unit 101, it prevents safety accidents. It is possible.

[0068] The first circuit section 102 has an appropriate range for controlling the heater 105 in the heated state. A certain current must flow, and either a low current or an overcurrent will flow through the first circuit section 102. When this occurs, it becomes difficult to control the heater 105 according to the target temperature profile.

[0069] For example, if an abnormality occurs in the first circuit section 102, the first circuit section 102 will perform aerosol generation. It is not possible to supply the heater with the current necessary to heat the material. Heater 1 If 05 is not heated, a feedback signal is sent to heat heater 105 to a predetermined temperature. When applied repeatedly, an overcurrent flows through the first circuit section 102, potentially leading to a safety accident.

[0070] Conversely, if almost no current flows through the first circuit section 102, the heater 105 will not heat up. Since the appropriate current cannot be supplied, it becomes difficult to sufficiently heat the aerosol-generating material. Therefore, Periodic communication between the control unit 101 and the first circuit unit 102 allows the flow through the first circuit unit 102. The first current quantity data needs to be received.

[0071] In one embodiment, the first circuit section 102 monitors the current flowing through the first circuit section 102. It also includes a current monitoring circuit that can be turned on. The ring circuit monitors the current for the control unit 101 to determine the operating state. It is also used for other purposes.

[0072] The control unit 101 actively controls each hardware configuration to facilitate aerosol generation. The control unit 101 performs overall control of the device 100. The control unit 101 has at least one processor and This also applies to the controller unit including Mori. According to one embodiment, the memo Ri can store computer code, and said computer code is at least When run by one processor, at least one processor is the control unit 101 To enable it to perform its function.

[0073] Referring to Figure 2, the control unit 101 controls the first circuit unit 102 and the second circuit unit 103. It is responsible for the following. As mentioned above, in the heated state, the control unit 101 is responsible for the first circuit unit 102. Control the temperature of the TA105 so that it reaches a temperature suitable for heating the aerosol-generating material. It is possible.

[0074] Furthermore, in the non-heating state, the control unit 101 controls the second circuit unit 103 and maintains a standby state. Alternatively, depending on the charging state, current will discharge from the battery 104, or the battery 104 will... Allow the current to charge.

[0075] Furthermore, the control unit 101 can determine the operating state of the aerosol generator 100. .

[0076] The control unit 101 monitors the current flowing through the first circuit unit 102, and the current value is If the value is above a certain level, it is determined to be a heated state; if it is below a certain level, it is determined to be a non-heated state. This is possible. The non-heating state also includes the charging state or the standby state.

[0077] The control unit 101 determines whether or not the second circuit unit 103 is supplied with current from an external charging device. Based on this, the operating state of the aerosol generator 100 is determined to be either a charging state or a standby state. It can be determined that there is one of them.

[0078] For example, the second circuit section 103 is supplied with current via the charging terminal 107, and externally It is also connected to a charging device. The current supplied from the charging terminal 107 is transmitted via the second circuit section 103. The current flows through the second circuit section 103, and the control unit 101 senses the current or electrical signal flowing through the second circuit section 103. The control unit 101 can determine the operating state as a charging state. Conversely, the charging terminal If it is not possible to sense the current flowing through the second circuit section 103 via 107 The control unit 101 can determine the operating state of the aerosol generator to be in standby mode.

[0079] Furthermore, the control unit 101 communicates with the first circuit unit 102 and the second circuit unit 103, and The current amount data and the second current amount data are received and the first circuit unit 102 and the second circuit unit 103 are configured to The occurrence of abnormalities in the aerosol generator 100 can be determined periodically and repeatedly. Cut.

[0080] Specifically, the control unit 101 monitors the current flowing through the first circuit section and aerosol The operating state of the generating device 100 is determined, and the first current amount data is obtained from the first circuit section or the second circuit section. The system can receive either the first or second current data and periodically determine whether an anomaly has occurred.

[0081] For example, in the case where current suddenly flows to the first circuit section where no current was flowing, the control unit 101 will... In this case, the operating state of the aerosol generator can be determined to be a heating state, and the first current quantity The system can receive data and determine how to handle any abnormalities.

[0082] The control unit 101 receives first current amount data from the first circuit unit 102, and the previously specified first current amount data If the threshold is exceeded, or if the second current amount data received from the second circuit section 103 is already specified By confirming that the second critical range has been exceeded, it is possible to determine whether an anomaly has occurred.

[0083] Meanwhile, the control unit 101, via the temperature sensor 106 located adjacent to the heater 105 The temperature data of the heater 105 can be received. This temperature data is used to generate aerosols. When determining the abnormality of the aerosol generator 100, by additionally considering the following, Which hardware configuration within the aerosol generator 100 causes an abnormality in the aerosol generator 100? This allows us to understand the concept of "Taka" (high / high) with even greater precision.

[0084] For example, if the first current data acquired by the control unit 101 is within the first critical range (for example, normal), The temperature data is within the normal range and is compared to the pre-designed temperature profile. If it is not within the normal range (for example), the control unit 101 determines that the cause of the abnormality is the heater 105 Alternatively, it can be determined that it is located at sensor 106. At this time, the control unit 101 determines that the user This can provide a warning indicating a malfunction of the heater 105 or sensor 106.

[0085] As another example, in the case of induction heating, the first current data of the first circuit section 102 is within the normal range. If, despite being present, the reading is lower than the normal range, it may be due to an abnormality such as a broken coil. It is possible to inform the user of something.

[0086] An abnormality in the aerosol generator 100 means that inside the aerosol generator 100... This means that at least one hardware configuration is not working or is malfunctioning. I will.

[0087] The control unit 101 detects when some or all of the components of the aerosol generator 100 malfunction. If this is determined, a variety of measures can be ordered.

[0088] For example, the control unit 101 can notify the user of any abnormality in any of its components. If a problem is found in the first circuit section 102, the first circuit section 1 Either the current flowing to 02 is cut off and the operation is stopped, or there is a malfunction in the second circuit section 103. If this is determined, the current flowing to the second circuit section 103 can be interrupted. Also, air If it is determined that there is an abnormality in the overall configuration of the aerosol generating device 100, The entire setup can be reset.

[0089] In such a control unit 101, the series of processes are performed periodically and iteratively, so aero This prevents the abnormal condition of the sol generating device from being left unattended indefinitely.

However, in addition to the components shown in Figures 3 to 5, there are other The fact that the aerosol generator 100 also includes the general-purpose components of the aerosol generator is that Those skilled in the art in the field relating to this embodiment will understand this. cormorant.

[0093] Furthermore, Figures 3 to 5 show that the aerosol generator 100 includes a heater 105. Although illustrated as such, heater 105 may be omitted if necessary.

[0094] Figure 4 shows the battery 104, control unit 101, and heater 105 arranged in a line. This is illustrated in Figure 4. Also, the battery 104, control unit 101, vaporizer 140 and The heaters 105 are shown arranged in a single line. Also, Figure 5 shows the steam generator. The diagram shows that 140 and heater 105 are arranged in parallel. However, The internal structure of the allosol generating device 100 is limited to what is shown in Figures 3 to 5. It is not that. In other words, the design of the aerosol generator 100 means that the battery 104 The arrangement of the control unit 101, heater 105, and steamer 140 may be changed.

[0095] When a cigarette 200 is inserted into the aerosol generator 100, the aerosol generator 1 00 activates the heater 105 and / or the steamer 140, and the cigarette lighter 200 and / Alternatively, an aerosol can be generated from the vaporizer 140. Heater 105 and / Alternatively, the aerosol produced by the vaporizer 140 passes through the cigarette 200 and the user It will be transmitted to.

[0096] If necessary, when the cigarette 200 is not inserted into the aerosol generator 100 Furthermore, the aerosol generator 100 can heat the heater 105.

[0097] The battery 104 supplies the power used to operate the aerosol generator 100. For example, the battery 104 is such that the heater 105 or the vaporizer 140 can be heated. It can supply power to the control unit 101, and it can supply the power necessary for the control unit 101 to operate. This is possible. In addition, the battery 104 is connected to the display provided in the aerosol generator 100. (i) It can supply the power necessary for sensors, motors, etc. to operate.

[0098] The control unit 101 controls the overall operation of the aerosol generator 100. Specifically, The control unit 101 controls not only the battery 104, heater 105 and vaporizer 140, but also air The control unit 101 controls the operation of other components included in the rosol generating device 100. The status of each component of the aerosol generator 100 is checked, and the aerosol generator 100 is operating. It is also possible to determine whether or not it is in a state where it can be made.

[0099] The control unit 101 includes at least one processor. This processor processes a number of logical gates. It is also embodied by an array of microprocessors, and the microprocessors The program that can be executed is also realized through its combination with the memory in which it is stored. Furthermore, the fact that it can also be realized by other forms of hardware means that this embodiment belongs to Anyone skilled in the art in that field should be able to understand it.

[0100] The heater 105 can be heated by power supplied from the battery 104. For example, When a cigarette is inserted into the aerosol generator 100, the heater 105 will turn on the cigarette. It can be located externally. Therefore, the heated heater 105 generates aerosols in the cigarette. It is possible to raise the temperature of a substance.

[0101] Heater 105 is also an electrical resistive heater. For example, heater 105 has electrical conductivity A track is included, and when current flows through the electrically conductive track, a heater 1 0 5 may be heated. However, the heater 105 is not limited to the example described above. This applies without limitation as long as it can be heated to the desired temperature. The temperature is either pre-set in the aerosol generator 100 or can be set to the desired temperature by the user. It can also be set to degrees.

[0102] On the other hand, as another example, heater 105 is also an induction heating heater.

[0103] For example, the heater 105 may be a tubular heating element, a plate heating element, a needle heating element, or a rod heating element. It also contains elements, and depending on the form of the heating element, it can heat the inside or outside of the cigarette 200. It can be heated.

[0104] Furthermore, the aerosol generator 100 is equipped with multiple heaters 105. Multiple heaters 105 are also arranged to be inserted inside the cigarette lighter 200, It is also placed on the outside of the Let 200. In addition, some of the multiple heaters 105 are cigarette lighters. It is positioned to be inserted inside the To 200, and the rest is positioned outside the Cigarette 200. Furthermore, the shape of the heater 105 is limited to the shapes shown in Figures 3 to 5. They are not limited to one shape, and can be manufactured in a variety of forms.

[0105] The vaporizer 140 can heat the liquid composition to generate an aerosol, and the generated aerosol The aerosol can pass through the cigarette 200 and be transmitted to the user. In other words, The aerosol generated by the vaporizer 140 enters the airflow passage of the aerosol generator 100. It can move along the airflow passage, and the aerosol produced by the vaporizer 140 The system is also configured so that the signal passes through the cigarette and is transmitted to the user.

[0106] For example, the vaporizer 140 may include a liquid storage section, a liquid transfer means, and a heating element. However, it is not limited to those. For example, liquid storage unit, liquid transfer means and heating element The element is also included in the aerosol generator 100 as an independent module.

[0107] The liquid storage section can store liquid compositions. For example, the liquid composition may be volatile. It is a liquid containing tobacco-containing substances, including tobacco flavor components, and also a liquid containing non-tobacco substances. The liquid storage section is also designed to be detachable from / attached to the vaporizer 140, and vaporization It is also made as a single unit with vessel 140.

The flavoring agent contains ingredients that can provide users with a variety of flavors or aromas. It is also a vitamin mixture containing vitamin A, vitamin B, vitamin C and vitamin B. It is also a mixture of at least one of E, but is not limited to them. .

[0109] Furthermore, the liquid composition is aerosol-forming, such as glycerin and propylene glycol. It also contains an agent.

[0110] The liquid transfer means can transfer the liquid composition from the liquid storage section to the heating element. For example, The liquid transmission means may be cotton fibers, ceramic fibers, glass fibers, or porous ceramics. It can also form a core (wick) like a spruce, but it is not limited to that.

[0111] The heating element is an element for heating a liquid composition that is transmitted by a liquid transmission means. For example, the heating element can be a metal heating wire, a metal heating plate, a ceramic heater, etc. It is not limited to those. Furthermore, the heating element may be a conductive fiber such as nichrome wire. It is also composed of lament and is arranged in a structure that is wrapped around the liquid transmission means. The heating element It is also heated by the electric current supply, transferring heat to the liquid composition in contact with the heating element, and the liquid The body composition can be heated. As a result, an aerosol may be generated.

[0112] For example, the steam generator 140 is also called a cartomizer or atomizer. These are some examples, but they are not limited to those.

[0113] Meanwhile, the aerosol generating device 100 includes a battery 104, a control unit 101, a heater 105 and In addition to the vaporizer 140, it also includes other general-purpose components.

For example, the cradle can be used to aerosol It is also used to charge the battery 104 of the generating device 100. Alternatively, the cradle and aero The heater 105 can be heated while connected to the sol generating device 100.

[0115] Cigarette 200 is also similar to a typical burning cigarette. For example, Cigarette The T200 also includes a first part containing an aerosol-generating substance and a second part containing a filter, etc. It is classified as such. Alternatively, the second part of Cigarette 200 may also contain aerosol-generating substances. For example, an aerosol-generating substance made in the form of granules or capsules also has a second part. It is inserted.

[0116] The entirety of the first part is inserted inside the aerosol generator 100, and the second part is outside It may be exposed to the elements. Or, only a portion of the first part may be inserted into the aerosol generator 100. Furthermore, the entirety of the first part and parts of the second part may be inserted. The user may insert parts of the second part. The aerosol can be inhaled by mouth. At this time, the aerosol is external The air is generated as it passes through the first part, and the generated aerosol then passes through the second part. It passes through and is transmitted to the user.

[0117] As an example, outside air is supplied to at least one air formed in the aerosol generating device 100. It also flows in through air passages. For example, an air passage formed in the aerosol generator 100. The opening and closing of the air passage, and / or the size of the air passage, can also be adjusted by the user. The amount of atomization, the smoking sensation, etc., can be adjusted by the user. Another example is that outside air is used in cigarettes. Through at least one hole formed on the surface of the cigarette 200, It also flows into the interior.

[0118] Figure 6 shows an example of an aerosol generation system using an induction heating method according to one embodiment. This is the drawing shown.

Therefore, in addition to the components shown in Figure 6, other general-purpose components are used in Aero. The fact that it is also included in the sol generating apparatus 100 is related to the technical field of this embodiment. Those skilled in the art will be able to understand this.

[0121] The induction coil 601 may be located around the cavity 603. Figure 6 shows the induction coil 601, It is illustrated that it is arranged to surround the susceptor 602 and cavity 603, It is not limited to that.

[0122] Once the cigarette 200 is placed in the cavity 603 of the aerosol generating device 100, aero The sol generating device 100 uses an induction coil 601 to generate an alternating magnetic field. Power can be supplied to the induction coil 601 to generate the energy. The alternating magnetic field generated by this process penetrates the susceptor 602, causing the susceptor 602 to heat up. The aerosol-generating substance inside the cigarette 200 is heated by the susceptor 602. Heating can generate aerosols. The generated aerosols can cause cigarette burns. It passes through T200 and is transmitted to the user.

It can supply the power necessary for play, sensors, motors, and other components to operate.

[0124] The control unit 101 controls the overall operation of the aerosol generator 100. Specifically, The control unit 101 controls not only the battery 104 and the induction coil 601, but also the aerosol generating device The control unit 101 controls the operation of other components included in the unit 100. In addition, the control unit 101 controls aerosol generation. The status of each component of the device 100 is checked, and the aerosol generator 100 is in an operational state. It is also possible to determine whether or not that is the case.

[0125] The induction coil 601 generates an alternating magnetic field using power supplied from the battery 104. It is also an electrically conductive coil. The induction coil 601 takes at least a portion of the cavity 603 They are also arranged to surround it. The alternating magnetic field generated by the induction coil 601 is inside the cavity 603. It is also applied to the susceptor 602 located at the end.

[0126] The susceptor 602 is activated when the alternating magnetic field generated from the induction coil 601 passes through it. It is heated and also contains metal or carbon. For example, susceptor 602 is ferrite ( ferrite), ferromagnetic alloy, stainless steel and It also contains at least one of the following: aluminium.

[0127] Furthermore, the susceptor 602 is made of graphite, molybdenum, and silicon dioxide. Silicon carbide, niobium, nickel alloy, gold Metal films, ceramics such as zirconia, nickel Transition metals such as Ni (nitrogen) and cobalt (Co), and semi-transition metals such as boron (B) and phosphorus (P) It also contains at least one of the metals. However, susceptor 602 is as described above. This example is not limited to the above; when an alternating magnetic field is applied, the temperature is heated to the desired level. If it is possible, it may apply without limitation. Here, the desired temperature is the aerosol temperature The temperature is pre-set in the device 100, and can also be set to the desired temperature by the user.

[0128] Once the cigarette 200 is placed in the cavity 603 of the aerosol generator 100, the susceptor 602 may be located inside the cigarette 200. Therefore, the heated susceptor 602 is This can increase the temperature of the aerosol-generating substances inside the cigarette 200.

[0129] Figure 6 illustrates how the susceptor 602 is inserted into the cigarette 200. However, it is not limited to that. For example, the susceptor 602 is a tubular heating element, plate type It may also include a heating element, a needle-shaped heating element, or a rod-shaped heating element, depending on the form of the heating element. The cigarette 200 can be heated either inside or outside.

[0130] Furthermore, the aerosol generator 100 may be equipped with multiple susceptors 602. Multiple susceptors 602 are also arranged to be inserted inside the cigarette 200. It is also placed on the exterior of the Galette 200. In addition, some of the multiple susceptors 602 are cigars. It is positioned to be inserted inside the Cigarette 200, and the rest is also positioned outside the Cigarette 200. Furthermore, the shape of the susceptor 602 is not limited to the shape shown in Figure 6. Furthermore, they can be manufactured in a variety of shapes.

[0131] The following describes an example of the Cigarette 200, referring to Figure 7.

[0132] Figure 7 is a diagram illustrating an example of a cigarette.

[0133] Referring to Figure 7, the cigarette 200 consists of a tobacco rod 210 and a filter rod 22 Including 0. The first part 210, described with reference to Figures 3 to 5, is the tobacco rod 210 The second part 220 includes a filter rod 220.

[0134] In Figure 7, the filter rod 220 is shown as a single segment, but it is not limited to that. It is not fixed. In other words, the filter rod 220 is made up of multiple segments. It is also composed of the first segment that cools the aerosol. It includes a second segment that filters out predetermined components contained in the aerosol. It is also a part of this. Furthermore, if necessary, the filter rod 220 can perform other functions. It also includes, at the very least, one additional segment.

[0135] The cigarette 200 is also packaged by at least one 240 flaps. 40 has at least one hole through which external air flows in or internal gas flows out. A can be formed. For example, a cigarette 200 can also be packaged by a single trumpet 240. As another example, a cigarette 200 can be superimposed by two or more trumpets 240. To be packaged. For example, the tobacco rod 210 is packaged by the first trumpet and then by the second trumpet. Therefore, the filter rod 220 can be packaged. And the packaged by individual wrappers The bellows rod 210 and the filter rod 220 are joined together, and the third bell opens the cigarette. The entire 200 can be further packaged. If the tobacco rod 210 or filter rod 220 If each consists of multiple segments, then each segment is individually wrapped. It is also packaged by a wrapper.

Bacolod 210 can also be made from shredded tobacco, which is tobacco sheets that have been cut into small pieces. Furthermore, the tobacco rod 210 is also surrounded by a heat-conducting material. For example, the heat-conducting material The quality can be that of metal foil, such as aluminum foil, but it is not limited to that. For example, the heat-conducting material surrounding the tobacco rod 210 transmits heat to the tobacco rod 210. This allows for even distribution of the heat received, improving the thermal conductivity applied to the tobacco rod. This allows for an improvement in the tobacco flavor. Also, remove the tobacco rod 210. The heat-conducting material that surrounds can function as a susceptor heated by an induction heater. At this time, although not shown in the drawings, the tobacco rod 210 also further includes an additional susceptor in addition to the heat-conducting material that surrounds it. The filter rod 220 is also a cellulose acetate filter. On the other hand, there is no limitation on the shape of the filter rod 220. For example, the filter rod 220 can also be a cylindrical rod or a tube-shaped rod containing a hollow inside. Also, the filter rod 220 can be a recessed rod. If the filter rod 220 is composed of a plurality of segments, at least one of the plurality of segments is also manufactured in a different shape.

[0138] The filter rod 220 is also made to generate a flavor.

[0141] If the filter rod 220 includes a segment for cooling the aerosol, the cooling segment is also manufactured from a polymer material or a biodegradable polymer material. For example, If the filter rod 220 includes a segment for cooling the aerosol, the cooling segment is also manufactured from a polymer material or a biodegradable polymer material. For example, The cooling segment may be made solely from pure polylactic acid, and is not limited to that. There is none. Alternatively, the cooling segment is made of a cellulose acetate filter with multiple pores. It can also be manufactured. However, the cooling segment is not limited to the examples described above. Furthermore, if it is capable of performing the function of cooling aerosols, then without limitation the It is possible.

[0142] On the other hand, although not shown in Figure 7, a cigarette 200 according to one embodiment has a front end It also includes a filter. The front filter is located on the tobacco rod 210. It is located on one side opposite the tobacco rod 220. The front end filter is located on the tobacco rod 210. This prevents the tobacco from detaching to the outside, and prevents liquefaction from the tobacco rod 210 during smoking. This prevents the generated aerosol from flowing into the aerosol generator 100 (Figures 3 to 6). It can be stopped.

[0143] Figure 8 shows an embodiment in which, based on the first current data or the second current data, the device differs. This is a flowchart for determining the usual course of action.

[0144] Referring to step 810, the control unit (e.g., control unit 101) controls the aerosol generator (e.g., For example, is the current operating state of the aerosol generator 100) heated or not heated? It is possible to determine whether or not a state exists.

[0145] The control unit detects when a current exceeding a predetermined value flows through the first circuit section (for example, the first circuit section 102). If this is determined, the operating state of the aerosol generator can be set to a heated state. Furthermore, the control unit activates when it detects that a current less than a predetermined value is flowing through the first circuit section. The state can be determined to be an unheated state.

[0146] In one embodiment, the aerosol generating device senses when a cigarette is inserted. It also further includes a cigarette insertion sensor. The cigarette insertion sensor is a cigarette After sensing that an insertion has occurred, the sensor transmits a sensing signal to the control unit, and the control unit receives the sensing signal. In response to the signal, control the second circuit unit (e.g., second circuit unit 103) and the battery (e.g., For example, the current from the battery 104) is applied to the first circuit section. If a current exceeding a certain value flows, the control unit will detect this and then the aerosol generating device The operating state of the device can be determined to be a heated state.

[0147] In another embodiment, the aerosol generator is a user interface that receives user input. It also includes a face. The control unit receives input signals from the user interface. It can receive. The control unit, in response to receiving the input signal, controls the second circuit unit. Control the current so that the battery current is applied to the first circuit. If current flows, the control unit will sense it, and the control unit will activate the aerosol generator. The operating state can be determined to be a heated state.

[0148] If the operating state of the aerosol generator is determined to be a heated state, proceed to step 820. If the operating state of the allosol generator is determined to be non-heating, proceed to step 840.

[0149] Referring to step 820, if the operating state is a heated state, the control unit controls the first circuit section The first current flowing through it can receive data.

[0150] When the operating state of the aerosol generator is determined to be the heating state, the control unit can determine that the main communication target is the first circuit unit. In the heating state, in order to determine the occurrence of an abnormality in the aerosol generator by the first circuit unit, the control unit can periodically receive the first current amount data of the first circuit unit .

[0151] Referring to step 830, when the operating state is the heating state, the control unit can additionally receive temperature data from a temperature sensor (e.g., temperature sensor 106). This step is an optional step, and when determining the occurrence of an abnormality in the aerosol generator, the temperature data can be additionally considered.

[0152] Referring to step 840, when the operating state is the non-heating state, the control unit obtains the second current amount data flowing through the second circuit unit. When the operating state of the aerosol generator is determined to be the non-heating state, the control unit can determine that the main communication target is the second circuit unit. In the non-heating state, in order to determine the occurrence of an abnormality in the aerosol generator by the second circuit unit, the control unit can periodically receive the second current amount data of the second circuit unit.

[0153] Referring to step 850, when the operating state is the heating state, based on the first current amount data, [[ID=3)5]] it is possible to determine the occurrence of an abnormality in the aerosol generator.

[0154] Specifically, compare the first current amount data with the first critical range, which is the current amount range expected in the heating state, and if the first current amount data is outside the first critical range, it can be determined that an abnormality has occurred in the aerosol generator.

[0155] In one embodiment, the control unit, based on the first current data and temperature data, determines the aerosol It is possible to determine whether an abnormality has occurred in the generating device. For example, the control unit can determine whether a temperature sensor or Then, by receiving additional heater temperature data, the first circuit in the heated state The task is to determine which component, the part or the heater, is malfunctioning. can.

[0156] If temperature data is not considered, it is difficult to know whether a heater malfunction has occurred, and the first circuit It may only be possible to know whether an abnormality occurred in the part. However, if the temperature data is added... By taking this into consideration, it becomes possible to determine more precisely whether abnormalities occur under heating conditions. can.

[0157] Referring to step 850, if the operating state is a non-heated state, based on the second current data This allows us to determine whether an abnormality has occurred in the aerosol generating device. Specifically, the second electric power The flow rate data is compared with the second critical range, which is the expected current range in the non-heated state. If the current data falls outside the second critical range, it is determined that there is a malfunction in the aerosol generator. It is possible.

[0158] The control unit determines whether the current state of the aerosol generator is in a charging state or a standby state. In either case, the second current quantity data can be monitored periodically. The second critical range of the second current data differs between the charging state and the standby state. It has also been specified that it should be done that way.

[0159] For example, in the charging state, current is supplied through the charging terminal, so compared to the standby state, In the current state, it can be expected that even more current will flow through the second circuit. Therefore, the second critical range is greater when the device is in a charged state than when it is in a standby state. And it can be designated even higher.

[0160] Thus, the aerosol generator is sensitive not only in the charging state but also in the standby state. Periodically, the second current quantity data is received, and the second critical range specified to be suitable for the standby state is set. By making comparisons, we can prevent potential hazards and accidents in all operating conditions. It is possible.

[0161] In step 850, the first critical range or the second critical range is simply defined as the first current quantity. In addition to comparing the data or the second current data, as described in Figure 2, Temperature data can be added and considered.

[0162] For example, if the temperature data is within the normal range, but an overcurrent flows through the first circuit, then The first current data exceeds the first critical range, causing the first circuit section to malfunction. It could mean that.

[0163] As another example, the first current data is within the first critical range, but the temperature data is within the heating temperature range. If the range cannot be reached, it means that the heater is not supplied with sufficient current by the first circuit section. Despite this, the heating fails, which could indicate a heater malfunction.

[0164] As yet another example, in the case of induction heating, the first circuit operates normally, and the first current data If the susceptor temperature does not rise despite being within the first critical range, induction occurs. This could also mean that a break has occurred in the coil.

[0165] As yet another example, even though the second circuit is in a charging state, the battery is not being charged. If only the current consumption increases, it could indicate a malfunction in the second circuit.

[0166] As yet another example, even though the second circuit is in standby mode, it needs power from the battery. If the above current flows, and an excessive overcurrent flows through the second circuit in the standby state, It can be tasted. This is because the second current data exceeds the second critical range, and the second circuit section This could mean a malfunction.

[0167] Referring to step 860, the series of processes described above causes the control unit to detect an abnormality in the aerosol generator. If it is determined to be live, the aerosol generator will be reset, the first circuit unit will cease operation, and the battery current will be cut off. Various measures can be ordered, such as termination or user warning notifications.

[0168] Specifically, when an overcurrent flows through the first circuit section in a heated state, the control unit performs the first... In order to stop the operation of the circuit section, current cannot be applied to the first circuit section, and the second circuit section is also connected. Alternatively, the electrical connection to the battery can be disconnected.

[0169] Alternatively, if a malfunction occurs in the control unit itself, in order to reset the aerosol generator, This includes initializing the state of all hardware configurations inside the aerosol generator. There are also others.

[0170] Alternatively, if an overcurrent flows through the second circuit section while the system is not heated, the control unit will... To prevent current from being applied to the part, the electrical connection to the battery or charging terminal is disconnected. The current can be blocked so that it does not flow to the second circuit section.

[0171] Furthermore, the aerosol generator also provides warning notifications to the user. The light generation device includes a user interface, an LED (Light Emitting Diode), or a vibration motor. It further includes data, and indicates a warning via the user interface, such as flashing an LED. Alternatively, it may include generating vibrations to signal the warning. However, However, it is not limited to those methods, and other notification methods besides those exemplified above may be used. Furthermore, it is also included that those skilled in the art in the field relating to this embodiment are skilled in the art. Then, it should be possible to understand.

[0172] Specifically, in the heated state, the first current data falls within the specified first critical range. Nevertheless, if the heater overheats, the control unit will notify the first circuit unit to continue operating the heater. To prevent overheating, the second circuit section is configured to interrupt the current flowing through the first circuit section. It can be controlled and the user can be given a heater overheat warning.

[0173] Furthermore, even though there is no temperature rise in the heater, the first current data of the first circuit section is If the critical range is exceeded, the control unit can stop the operation of the first circuit section. In the case of heat, if an overcurrent is applied to an induction coil even though no induced current is generated, then induction occurs. This allows the user to be notified of a coil break or other malfunction.

[0174] Furthermore, in the aerosol generator, when the second current amount data is specified, the second current amount data is set to the second current amount data. If the battery does not charge properly despite being within the critical range, a problem has occurred with the battery. This decision allows for a warning to be issued indicating a battery failure.

[0175] Alternatively, in the aerosol generator, when the device is charged, the second current data is specified as the second 2. When the critical range is not met, or when in standby mode, the second current data indicates that the charging state is not met. If the result does not fall within the specified second critical range, it is determined that an abnormality has occurred in the second circuit. Furthermore, it can provide a warning notification indicating a malfunction in the second circuit section.

[0176] Furthermore, in the charging state, the second current data flowing through the second circuit section is within the second critical range. If the value is much lower than the range, it may indicate that charging has not been done correctly. Conversely, if the second current data has a very high value, it indicates that the battery is being overcharged. Problems may arise. To prevent this, the aerosol generator is connected to the battery from the second circuit section. It can interrupt the current flowing through it.

[0177] Furthermore, the aerosol generator is not charged, and only the second current data is measured as high. In that case, the user will be given a battery replacement notification signal, or a second battery replacement will be initiated from the charging terminal. It can interrupt the current flowing through the circuit.

[0178] Furthermore, in standby mode, if the second current data flowing through the second circuit exceeds the second critical range... In such cases, the battery may supply more current than necessary to the control unit, first circuit unit, or heater, etc. Since it will also flow into other hardware components of the aerosol generating device, aerosol The generating device either cuts off the current flowing from the second circuit section to other components, or allows the user to... It can provide a fault notification signal for the two circuits.

[0179] Figure 9 shows a flowchart that determines whether a device is malfunctioning based on communication results, according to one embodiment. It is.

[0180] Referring to stage 900, it means that the aerosol generator is operating normally, and the cycle If no abnormalities are detected in the current monitoring or data-based communication monitoring, This also applies.

[0181] Referring to step 910, the control unit determines whether the current operating state is a heated state or not. It is possible to determine whether it is in a heated state or not. Whether or not it is in a thermal state is determined by the control unit, as described above, in step 920. If the operating state is a heated state, the control unit inputs the first data to the first circuit unit. This is possible. If there is no abnormality in the control unit, the first data is input to the first circuit unit, and When the event occurs normally, the first data is not input to the first circuit section.

[0182] Referring to step 930, after the control unit inputs the first data to the first circuit unit, a certain period of time After this process, the second data can be read from the first circuit section. If it is running, after receiving the first data from the control unit, a certain period of time has elapsed, and then the first The data can be changed to the second set of data. For details on this, please refer to Figure 10. This will be explained later.

[0183] Referring to step 940, the control unit determines whether the first data and the second data are identical. This allows us to compare the following. If they are identical, we move to stage 950, and if they are not identical, If not, the first circuit section has changed the first data to the second data, so the first The circuit section is determined to be functioning normally, and the process returns to step 900. That is, the first data and If the second data is not identical, then both the control unit and the first circuit unit will be operating normally. This is also understood.

[0184] Referring to step 950, the fact that the first data and the second data are identical means that the first This can be understood as being because the circuit section cannot change the first data to the second data. As a result, the control unit determines that an abnormality has occurred in the first circuit section and stops the operation of the first circuit section. It is possible.

[0185] Referring to step 960, in step 920, the control unit inputs the first data to the first circuit unit. The reason it could not be done is believed to be a malfunction in the control unit, indicating an abnormality in the control unit. It is also determined that this is due to [the cause].

[0186] If an abnormality occurs in the control unit, the first circuit unit will receive a command from the control unit and stop its operation. Since this is not possible, the first circuit section will cease operation, resulting in heater overheating or overcurrent in the first circuit section. This can prevent safety accidents like the one described.

[0187] Steps 970 to 990 are the non-heated state portion of the flowchart in Figure 8 (step 840) The process can also be carried out using the same method as in stages 850 and 860.

[0188] Figure 10 illustrates a concept illustrating a communication method between the control unit and the first circuit unit according to one embodiment. This is a diagram.

[0189] The control unit 101 periodically inputs (writes) the first data 1020 to the first circuit unit 102. (1010). The control unit 101 and the first circuit unit 102 both actively perform control functions. However, the control unit 101 and the first circuit unit 102 are a master device and a slave device. This also relates to the relationship with (slave) devices.

[0190] The master device is the subject of action in performing one task, and other slave devices... The vise can be controlled. On the other hand, the slave device belongs to the master device. It is a device that can perform operations by receiving instructions from the master device. .

[0191] In other words, the control unit 101 can control the first circuit unit 102, but the first circuit unit 102 cannot control the control unit 101. For example, the control unit 101 controls the first circuit Input data into unit 102 (1010), or read data from the first circuit unit 102. It can be taken (1050), but the first circuit unit 102 inputs data to the control unit 101. Alternatively, it may not be possible to read data from the control unit 101.

[0192] The first data 1020 periodically checks whether communication with the first circuit unit 102 is being performed correctly. This data is also used to confirm that. It is transmitted from the control unit 101. The first circuit unit 102, upon receiving the first data 1020, processes the first data 1020 into the first data 1 The data can be changed (1030) using a second data 1040, which is different from 020.

[0193] Such data modification (1030) process is subsequently read by the control unit 101 ( 1050) In the process of determining whether or not it is identical to the first data 1020 There are also others.

[0194] The data change (1030) method performed by the first circuit section 102 is called the toggle method. However, for example, the input data is simply a 1-bit difference from other data via a toggle mechanism. It will also be changed. The control unit 101 will confirm that the changed data and the input data are the same. By continuously comparing whether or not communication is working, it is possible to determine whether communication is working correctly between each circuit. Whether or not this is happening can be easily checked using only a small amount of power.

[0195] In other words, if the control unit 101 is operating normally without any abnormalities occurring, then the control unit 101 This involves periodically inputting the first data 1020 to the first circuit section 102 (1010). This is possible. If an abnormality occurs in the control unit 101, the first circuit unit 102 will process the first data 1020. Because no input is received, the first circuit unit 102 indirectly causes an abnormality in the control unit 101. The condition of the animal can be confirmed.

[0196] Conversely, if the first circuit section 102 is operating normally without any abnormalities occurring, then the first circuit section 102 periodically changes the second data 1040, which is different from the first data 1020 before it was changed. The data must be changed (1030) (in Figure 10, the second data is S2 and Although expressed, if the data modification fails, the second data will be essentially the same as the first data. (This could mean that the data is the same.)

[0197] Whether the first circuit section 102 has correctly performed the data change (1030) is, The control unit 101 reads data from the first circuit unit 102 (1050), and the first data 102 Compare 0 with the second data point 1040 to confirm whether the two are identical or not. This can be indirectly confirmed.

[0198] For example, if the first data 1020 and the second data 1040 are different, then the first circuit section 10 If 2 is functioning correctly and the two data are different, then the first circuit section 102 This indicates a failure in data modification (1030), therefore the first circuit section 102 does not operate normally. It appears that they haven't done so.

[0199] In this way, the control unit 101 and the first circuit unit 102 communicate periodically via data communication. 101 and the first circuit unit 102 can check each other for abnormalities.

[0200] In other words, if an abnormality occurs in the control unit 101, the first circuit unit 102 will cease its own operation. If an abnormality occurs in the first circuit section 102, the control unit 101 will... This stops the operation of 102 and prevents abnormal overheating or overcurrent in heater 105. It is possible.
