[0016] The following examples are based on the attached drawings and are intended for those with ordinary skill in the art to which the invention belongs. The instructions will be detailed so that they can be easily implemented by the user. However, the examples are in various different forms. This can also be embodied in the form, and is not limited to the embodiments described herein.

[0017] The embodiments of this disclosure will be described in detail below with reference to the drawings. Figure 1 is a block diagram showing an aerosol generation system according to one embodiment.

[0018] Referring to Figure 1, the aerosol generation system consists of an aerosol generator 100 and an aerosol generator. It may contain sol product 15. In one embodiment, the aerosol generating apparatus 100 is aero It may include a containment space into which the sol product 15 is inserted. For example, an aerosol generating device 100 This involves heating the aerosol product 15 inserted into the containment space to generate an aerosol. It is possible. The aerosol product 15 corresponds to a cigarette, but is not necessarily limited to one. There is nothing that can be determined. Aerosol product 15 is an article containing an aerosol-generating substance. If so, it may apply without restriction.

[0019] In one embodiment, the aerosol generator 100 includes a processor 110, a heater 120 and The sensing module 130 may be included. However, the internal structure of the aerosol generator 100 The construction is not limited to what is shown in Figure 1. In the hardware configuration shown in Figure 1, some components may be omitted, or new configurations may be added. Anyone with ordinary skill in the art related to this embodiment would know that it is possible to add it. They will understand.

[0020] In one embodiment, the heater 120 is inserted into the containment space of the aerosol generator 100. The aerosol product 15 can be heated.

[0021] For example, heater 120 is also an induction heating type heater. Specifically, heater 120 is , an induction coil for heating the aerosol product 15 by induction heating method and the induction coil Therefore, it may include a susceptor through which the generated variable magnetic field can pass and be heated.

[0022] As another example, heater 120 is also an electrical resistance heater. Specifically, heater 120 It includes a conductive track, and when current flows through the conductive track, It may be heated. However, the heater 120 is not limited to the above example, and may be heated to the desired temperature. Anything that meets the criteria may be applicable without restriction. In this case, the desired temperature is the aerosol generator 10 It may be pre-set to 0, or it may be set to a desired temperature by the user.

[0023] In one embodiment, the sensing module 130 includes an inductive sensor 132 and It may include at least one of the temperature sensors 134. For example, inductive sensor 1 32 is whether the aerosol product 15 is removed into the containment space of the aerosol generating device 100. It senses whether it has moved or been inserted, at least partially. Inductive sensor 13 2. The aerosol product 15 is removed from the containment space or at least partially moved. Alternatively, it is possible to sense the change in inductance of the housing space caused by the insertion. In this case, the aerosol product 15 may contain a metallic substance such as aluminum. For example, the temperature sensor 134 detects aerosol products in the containment space of the aerosol generator 100. It can sense whether item 15 is removed, at least partially moved, or inserted. Yes, it is possible. The temperature sensor 134 detects when the aerosol product 15 is removed from the containment space or when there is a small amount of it. Even without it, it can sense temperature changes caused by partial movement or insertion. can.

[0024] In one embodiment, the aerosol product 15 is contained within the containment space of the aerosol generating device 100. Once it determines whether or not it has moved, the processor 110 counts the time specified. This can be started. For example, the aerosol product 15 is moved for a specified time. This refers to the waiting time from the moment the aerosol product 15 is inserted to determine whether or not it will be reinserted. The specified time may be set to a different value depending on the manufacturer's design, user settings, etc. .

[0025] In one embodiment, the processor 110 controls the inductive sensor 132 for a specified time. Inductance changes can be sensed via this. For example, processor 110 can sense aerosol The change in inductance can be detected within 5 seconds from the moment the finished product 15 is moved. The processor 110, for the 5 seconds, reinserts the aerosol product 15 into the inductor It can sense whether or not a change has occurred. In one embodiment, the processor 110 senses the presence or absence of change. Based on the change in inductance, it is possible to determine whether or not to supply power to the heater 120. .

[0026] In one embodiment, the processor 110 controls the overall operation of the aerosol generator 100. It is also the hardware that controls it. For example, the processor 110 controls the heater 120 and the sensor Not only the ranging module 130, but also the movement of other components included in the aerosol generator 100 The operation can be controlled. In one embodiment, the processor 110 controls the aerosol generator 100 Check the status of each component and determine whether the aerosol generator 100 is operational or not. It is also possible to make that judgment.

[0027] Figure 2 shows how to control the power supply to the heater in the aerosol generation system shown in Figure 1. And this is a flowchart.

[0028] Referring to Figure 2, the processor (for example, processor 110 in Figure 1) is in operation 201. In this case, via a sensing module (for example, the sensing module 130 in Figure 1) Aerosol product in a state inserted into the containment space (for example, the aerosol product in Figure 1) Item 15) is the containment space of the aerosol generating device (for example, the aerosol generating device 100 in Figure 1). It can detect whether or not it has moved from its original location.

[0029] In one embodiment, the processor 110 controls an inductive sensor (for example, the inductive sensor shown in Figure 1). The inductance change is detected via the ductive sensor 132), and the aerosol product It is possible to detect whether or not 15 has moved out of the containment space of the aerosol generating device 100. For example, an aerosol product inserted and located in the containment space of the aerosol generating device 100. Item 15 may contain a metallic substance. One side of the inductive sensor 132 generates a magnetic field. A metallic substance located within the magnetic field generated by the inductive sensor 132 (and If the magnetic material is moved, the processor 110 will, through the inductive sensor 132 The processor can detect that the inductance value changes due to the movement of metallic material. 110 indicates that if the deformed inductance value is greater than the threshold, aerosol products It can be detected that item 15 has been moved from the containment space of the aerosol generating device 100.

[0030] In other embodiments, the processor 110 uses a temperature sensor (for example, the temperature sensor 1 in Figure 1). 34) The temperature change is sensed via the aerosol product 15 in the aerosol generating device 100 It can sense whether or not it has moved out of its containment space. For example, the containment space of the aerosol generator 100 If the aerosol product 15, which is inserted and positioned in space, moves, the temperature sensor will react to the air. The processor 110 can detect a rapid increase in the internal temperature of the rosol generator 100. If the increased internal temperature is greater than the threshold temperature, the aerosol product 15 becomes an aerosol It can also be detected if the device has moved out of the containment space of the generating device 100.

[0031] According to one embodiment, in operation 203, the processor 110 changes the inductance and The power supply to the heater 120 is controlled based on at least one of the temperature changes. It is possible.

[0032] In one embodiment, the processor 110 detects the inductance change for a specified time. If the magnitude of the change is below a threshold, the power supply to the heater 120 may be interrupted. Yes, it is possible. For example, if the specified time is 5 seconds, the processor 110 will sense for 5 seconds. If the magnitude of the inductance change is smaller than the threshold, the aerosol product 15 If it is determined that the part has not been reinserted, the power supply to the heater 120 may be interrupted. The interruption of power supply to heater 120 indicates that the user has stopped smoking. It tastes good.

[0033] In another embodiment, the processor 110 senses the inductance for a specified time. If the magnitude of the change exceeds a threshold, maintain the power supply to heater 120. This is possible. For example, if the specified time is 5 seconds, the processor 110 will sense for 5 seconds. If the magnitude of the inductance change is greater than or equal to the threshold, the aerosol product 15 The system determines that the component has been reinserted and can maintain power supply to the heater 120.

[0034] In one embodiment, heater 1 is controlled based on the sensed inductance change over a specified period of time. By determining whether or not to supply power to 20, the aerosol generator 100 will determine the power supply Consumption can be improved. For example, conventional aerosol generators produce aerosol products The heater is automatically turned off and heating is interrupted when the material is removed. Contrary to the user's intention, the aerosol product is accidentally moved from the aerosol generator. In cases where (for example, if the aerosol product gets on your lips and leaves the aerosol generator) However, if the heater is automatically turned off and heating is interrupted, the user can turn off the heater. It must be turned on again to start heating. This will disrupt conventional aerosol generation. The device has problems such as inconvenience in use and wasted power due to frequent power control. The aerosol generating apparatus 100 in the embodiment of the present invention is configured to allow for a specified time to After detecting a change in ductance, if it is detected that the aerosol product 15 has moved, By turning off the power to the TA120 and interrupting the heating process, the issue that occurred in conventional technology is resolved. The problems can be resolved.

[0035] In one embodiment, the processor 110 detects the magnitude of the temperature change over a specified period of time. Based on this, the power supply to the heater 120 can be controlled. For example, if the specified time is 5 If the value is seconds, the processor 110 will determine if the magnitude of the temperature change detected over 5 seconds exceeds the threshold. If the value is small, it is determined that the aerosol product 15 has not been reinserted, and the heater 120 is then... The power supply may be interrupted. In this case, the power supply to the heater 120 will be stopped. This signifies the end of smoking by the user. Another example is when the specified time is 5 seconds. If the magnitude of the temperature change detected over 5 seconds is greater than or equal to a threshold, the processor 110 will... The system determined that the aerosol product 15 had been reinserted and maintained power supply to the heater 120. It is possible.

[0036] In other words, when the aerosol product 15 is reinserted, the temperature of the heater 120 As the temperature decreases, the processor 110 compares the degree of decrease in the heater 120 temperature with a previously set threshold. This allows for control of the power supply to the heater 120.

[0037] Figure 3 shows a method for controlling the inductive sensor of an aerosol generator according to one embodiment. This is a diagram illustrating the explanation.

[0038] Referring to Figure 3, the processor (for example, processor 110 in Figure 1) when specified During the interval of 300, an inductive sensor (for example, inductive sensor 132 in Figure 1) The inductance change can be sensed through this. For example, the processor 110 uses PWM (pul The voltage of the inductive sensor 132 is obtained using the (se width modulation) method. It is possible to control and sense the change in inductance. In this case, the processor 110 The number of times the inductive sensor 132 is switched to the activated state within a set time of 300. This can be set in advance. Figure 3 shows the inductive sensor during a specified time of 300. It has been shown that 132 can be switched to the activated state five times, but it is not limited to that.

[0039] In one embodiment, the processor 110 processes an aerosol product (for example) at a first time point 310. For example, the aerosol product 15) in Figure 1 is an aerosol generating device (for example, the aerosol in Figure 1) It can be determined that it has been moved from the containment space of the generating device 100). The first time point 310 is designated This refers to the start time of counting at 300.

[0040] In one embodiment, the processor 110 sets the inductive sensor 13 at the second time point 320. The supply voltage to 2 is controlled to switch the state of the inductive sensor 132 to the activated state. This can be achieved. At this time, the processor 110 will supply a heater from the battery to the second time point 320. The power supplied to (for example, heater 120 in Figure 1) is cut off. That is, processor 1 10 is an operation to cut off the power supplied to the heater 120 and an inductive sensor 132 The operation of switching the state to the activated state can be performed in parallel. In one embodiment, the second When the power supplied to the heater 120 is cut off at point 320, the aerosol generator The internal temperature of 100 can be substantially reduced. Sensed by the inductive sensor 132. The inductance value can be distorted at high temperatures, so the processor 110 is the heater 120 The heating is periodically interrupted, and the inductance change is detected via the inductive sensor 132. To know.

[0041] In one embodiment, the processor 110 controls the inductive sensor 13 at the third time point 330. The state of 2 can be switched to an inactive state. In this case, the processor 110 is the third The power supply from the battery to the heater 120 can be controlled to occur at time 330. The processor 110 operates to supply power to the heater 120 and the inductive sensor 1 The operation of switching the state of 32 to the deactivated state can be performed in parallel. In one embodiment, At the third time point 330, power is supplied to the heater 120, thereby enabling the aerosol generator 10 The internal temperature of 0 can increase substantially.

[0042] In one embodiment, the processor 110 performs a minimum from the first time point 310 to the fourth time point 340. The inductance changes at least once (for example, 5 times) via the inductive sensor 132. It can sense the change. The processor 110 operates from the first time point 310 to the fourth time point 340. Based on the inductance change detected during the specified time of 300, aerosol generation It is possible to determine whether or not item 15 has been reinserted. For example, from the first time point 310 to the fourth time point 34 The inductance change detected during the specified time period of 300 is less than the threshold value. In this case, the processor 110 determines that the aerosol product 15 has not been reinserted, If the value is greater than or equal to the threshold, the processor 110 will determine that the aerosol product 15 has been reinserted. It is possible to make a judgment.

[0043] Figure 3 shows the aerosol product 15 being moved out of the containment space of the aerosol generator 100. The figures illustrate subsequent time points, but are not limited thereto. In other embodiments, Aero It is determined whether or not the sol product 15 has moved out of the containment space of the aerosol generating device 100. In this case, the method for controlling the voltage of the inductive sensor 132 in Figure 3, and the heater The same power control method can be applied.

[0044] Figure 4 shows an aerosol generating apparatus according to one embodiment that determines whether or not the aerosol product is moving. This is a flowchart showing the process. Figure 4 is used to specifically explain the operation 201 in Figure 2. Since this is a flowchart, in the explanation related to Figure 4, please check whether it corresponds to the content mentioned above. Identical or similar content may be omitted.

[0045] Referring to Figure 4, the processor (for example, processor 110 in Figure 1) operates 201a In this case, via an inductive sensor (for example, inductive sensor 132 in Figure 1) The first inductance change can be detected at a constant period. For example, the first inductance The change is the minimum inductance change that indicates the aerosol product 15 has been moved. It can mean a value.

[0046] In one embodiment, the processor 110 operates the inductive sensor 13 at a constant cycle. The state in step 2 is switched to the activated state and supplied to the heater (for example, heater 120 in Figure 1). The power can be cut off. At this time, at a certain period, the inductive sensor 132 is used to transmit signals. This refers to the optimal period for detecting changes in temperature. For example, if the constant period is set to 1 second. The processor 110 switches the state of the inductive sensor 132 to the activated state at 1-second intervals. This can be used to interrupt the power supplied to heater 120.

[0047] In one embodiment, the processor 110 controls the inductive sensor 132 for a certain period of time. After switching the state to the activated state, data related to the change in inductance is acquired, and Switch the state of the ductive sensor 132 to the deactivated state. For example, if the period is 1 second If configured, the processor 110 activates the state of the inductive sensor 132. After switching, data related to the change in inductance is acquired for 0.7 seconds, and the inductance The state of the IV sensor 132 can be switched to an inactive state and held for 0.3 seconds.

[0048] According to one embodiment, in operation 201b, the processor 110 performs an inductive sensor The magnitude of the first inductance change detected through SA132 is greater than or equal to the first threshold. It is possible to determine whether or not. For example, the first threshold is the aerosol product containing a metallic substance. (For example, aerosol product 15 in Figure 1) is an aerosol generator (for example, air in Figure 1) The maximum amount of inductance change generated by movement from the housing space of the rosol generation device 100) It means a small value.

[0049] In one embodiment, the magnitude of the detected first inductance change is greater than or equal to the first threshold. If it is determined that there is an aerosol product, the processor 110, in operation 201c, It can be sensed that 15 has been moved. In other embodiments, the sensed first inductance change If the magnitude of the change is determined to be less than the first threshold, the processor 110 will perform operation 201 Returning to a, you can repeat the following actions.

[0050] Figure 5 shows an aerosol generating apparatus according to one embodiment, which differs depending on whether or not an aerosol product is inserted. This flowchart shows how to control the power supply to the heater. Figure 5 is the same as Figure 2. This flowchart is intended to specifically explain operation 203, and therefore, the explanation of Figure 5 is as follows: In this context, content that corresponds to, is identical to, or is similar to the content mentioned above may be omitted.

[0051] Referring to Figure 5, the processor (for example, processor 110 in Figure 1) operates 203a In this case, the sensing time t for inductance change can be set to 1. For example, The sensor 110 sets the inductance change sensing time t to 1 and sets the specified time (for example) Then, the counting can be performed for the specified time (300) shown in Figure 3.

[0052] According to one embodiment, in operation 203b, the processor 110 performs an inductive sensor The second inductance change is detected via a sensor (for example, the inductive sensor 132 in Figure 1). It can be determined. For example, the change in the second inductance is due to the aerosol product 15 being re-examined. This refers to the minimum inductance change value at which insertion is deemed to have occurred.

[0053] In one embodiment, the processor 110 operates the inductive sensor 13 at a constant cycle. The state in step 2 is switched to the activated state and supplied to the heater (for example, heater 120 in Figure 1). The power can be cut off. At this time, at a certain period, the inductive sensor 132 is used. This refers to the optimal period for sensing changes in inductance. For example, if the constant period is set to 1 second. If so, the processor 110 activates the state of the inductive sensor 132 at 1-second intervals. The system can be switched to a controlled state, which can cut off the power supplied to the heater 120.

[0054] In one embodiment, the processor 110 controls the inductive sensor 132 for a certain period of time. After switching the state to the activated state, data related to the change in inductance is acquired, and The state of the ductive sensor 132 can be switched to an inactive state. For example, a constant When the period is set to 1 second, the processor 110 checks the state of the inductive sensor 132. After switching to the activated state, data related to the change in inductance is acquired for 0.7 seconds. Switch the state of the inductive sensor 132 to the deactivated state and hold it there for 0.3 seconds. It is possible.

[0055] According to one embodiment, the processor 110, in operation 203c, performs an inductive sensor The magnitude of the second inductance change detected through SA132 is greater than or equal to the second threshold. It is possible to determine whether or not this is the case. For example, the second threshold is the aerosol product containing a metallic substance. (For example, aerosol product 15 in Figure 1) is an aerosol generator (for example, air in Figure 1) The inductance change that occurs when the rosol is reinserted into the housing space of the rosol generating device 100) It represents the minimum value of the concentration.

[0056] In one embodiment, the magnitude of the detected second inductance change is greater than or equal to the second threshold. If it is determined that power is available, the processor 110 will supply power to the heater 120 in operation 203d. Maintain the supply. For example, if the magnitude of the detected second inductance change is greater than or equal to the second threshold. If it is determined that this is the case, the processor 110 will supply power from the battery to the heater 120. It can be held.

[0057] In other embodiments, the magnitude of the detected second inductance change is less than the second threshold. If it is determined that this is the case, the processor 110 changes the inductance in operation 203e. The detection time t is the specified time (t 指定 It is possible to determine whether or not it is identical to ).

[0058] In one embodiment, the sensing time t for the change in inductance is the same as the specified time. If determined, the processor 110 will sense the change in inductance during operation 203g. Time t can be calculated as t+1. For example, the sensing time for inductance change is 1 second (t= 1) The specified time is 5 seconds (t 指定 If = 5), then processor 110 is The inductance change can be calculated using a detection time of 2 seconds (t=2). From here on, processor 11 0 returns to operation 203b, and the following operations can be repeated.

[0059] In one embodiment, the sensing time t for the change in inductance is the same as the specified time. If determined otherwise, the processor 110 controls the power to the heater 120 during operation 203f. The supply can be interrupted. For example, the sensing time for inductance change is 5 seconds (t=5). The specified time is 5 seconds (t 指定 If = 5, then processor 110 will The power supplied from the heater 120 can be cut off.

[0060] Figure 6A shows the aerosol generation when the aerosol product according to one embodiment is in the first state.

[0068] Figure 7A is a diagram illustrating the elements constituting an aerosol generating apparatus according to one embodiment. be.

[0069] Referring to Figure 7A, the aerosol generator 100 consists of a susceptor 122 and an induction coil 12 4. May include a battery 115 and a processor 110. However, it may include, as shown in Figure 1. In addition to the elements shown, other general-purpose elements may be further included in the aerosol generator 100. .

[0070] The aerosol generator 100 uses induction heating. By heating the aerosol product 15 contained in the aerosol generating device 100, Allosols can be generated. The induction heating method involves heating the susceptor 122, which generates heat due to an external magnetic field, to the surrounding area. Alternating magnetic field (a field whose direction changes periodically) This could mean a method in which a heat is applied to the susceptor 122 to generate heat.

[0071] When an alternating magnetic field is applied to the susceptor 122, the susceptor 122 exhibits eddy current loss. Current loss and hysteresis loss Energy loss occurs, and the lost energy is converted into thermal energy in the susceptor 122 It can be emitted from. The larger the amplitude or frequency of the alternating magnetic field applied to susceptor 122, the greater the emission. A large amount of thermal energy can be released from the susceptor 122. Aerosol generator 100 By applying an alternating magnetic field to the susceptor 122, thermal energy is released from the susceptor 122. The thermal energy released from the susceptor 122 is transferred to the aerosol product 15. In one embodiment, the susceptor 122 is shaped into sections, slices or strips. It may be provided in the aerosol generating device 100.

[0072] At least a portion of the susceptor 122 is made of ferromagnetic material. It can be formed by (stance). For example, susceptor 122 contains metal or carbon. See.

[0074] The susceptor 122 is used for the aerosol product 15 contained in the aerosol generator 100. It can surround at least a portion of the outer surface. For example, susceptor 122 can surround aerosol products. The tobacco medium contained in product 15 can be surrounded. Thereafter, the tobacco medium is separated from the susceptor 122. Heat can be transferred more efficiently through quality.

[0075] The induction coil 124 may be provided in the aerosol generating device 100. An alternating magnetic field can be applied to the susceptor 122. When power is supplied to the conductor coil 124, a magnetic field may be formed inside the induction coil 124. When an alternating current is applied to the induction coil 124, a magnetic field is formed inside the induction coil 124. The direction can be continuously changed. The susceptor 122 is located inside the induction coil 124 and periodic When exposed to an alternating magnetic field whose direction changes, susceptor 122 generates heat and aerosols are produced. The aerosol product 15 contained in the containment space of the apparatus 100 may be heated.

For example, the induction coil 124 is susceptible It extends to a length corresponding to the length of ta 122, or to a length longer than the length of susceptor 122. It can extend.

[0078] The induction coil 124 can be positioned in a location suitable for applying an alternating magnetic field to the susceptor 122. For example, the induction coil 124 may be positioned in a location corresponding to the susceptor 122. The alternating magnetic field of the induction coil 124 is determined by the size and arrangement of the induction coil 124. The efficiency applied to 22 can be improved.

[0079] If the amplitude or frequency of the alternating magnetic field formed by the induction coil 124 is changed, The degree to which the susceptor 122 heats the aerosol product 15 can also be changed. Induction coil 1 The amplitude or frequency of the magnetic field produced by 24 is changed by the power applied to the induction coil 124. Therefore, the aerosol generator 100 adjusts the power applied to the induction coil 124. This allows for control of the heating of the aerosol product 15. For example, in an aerosol generator. 100 can control the amplitude and frequency of the alternating current applied to the induction coil 124.

[0080] As an example, the induction coil 124 is embodied by a solenoid. The induction coil 124 is along the inner surface of the outer housing of the aerosol generator 100. It is also a solenoid that is wound with a susceptor 122 and aerozo Product 15 may be located. The material of the conductor constituting the solenoid is also copper (Cu). However, it is not limited to silver (Ag), gold (Au), aluminum (Al), tungsten One or less of the following: tene (W), zinc (Zn), and nickel (Ni) The alloy containing at least one of these elements can make up the material of the wires that constitute the solenoid.

For example, the conversion section may include a class-D amplifier. This can be realized through the low-pass filter that constitutes the load network of the mplifier. ru.

[0084] The processor 110 can control the power supplied to the induction coil 124. The regulator 110 adjusts the power supplied to the induction coil 124 using battery 11 5 can be controlled. For example, the processor 110 controls the temperature of the susceptor 122. The susceptor 122 controls the temperature at which it heats the aerosol product 15 to maintain a constant temperature. They are able to perform their duties.
