Description

Technical Field

[0001] The present invention relates to an aerosol generating device, and more particularly to an aerosol generating device capable of controlling a heating temperature.

[0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2022-0096634 filed on August 3, 2022, the disclosure of which is incorporated herein in its entirety as a part of this specification. Background Art

[0003] In recent years, there has been an increasing demand for alternative smoking products that overcome the shortcomings of conventional aerosol-generating products. For example, there has been an increasing demand for devices that generate aerosols by electrically heating aerosol-generating product rods (e.g., aerosol-generating product-type electronic cigarettes). Therefore, research on electrically heated aerosol-generating devices and aerosol-generating product rods (or aerosol-generating products) applied to the aerosol-generating devices is being actively conducted.

[0004] The aerosol generating device may include a heating unit capable of controlling the heating temperature inside the device. The heating unit may control the heating temperature for heating the aerosol generating article, or may control the heating temperature for heating the vaporizing unit. In this case, the heating unit may control the heating temperature inside the aerosol generating device according to the user's preference for using the aerosol generating device. Alternatively, the heating unit may control the heating temperature under various conditions according to the conditions inside the aerosol generating device.

[0005] For example, the vaporization unit may include an aerosol-generating substance, and the heating unit may emit the aerosol-generating substance by applying heat to the aerosol-generating substance. When the heating unit continues to heat in the vaporization unit, even when the aerosol-generating substance in the vaporization unit is completely consumed, the heating unit disposed in the vaporization unit may be damaged.

[0006] Therefore, further research and development is required on a specific method that can automatically or manually control the heating temperature of the aerosol generating device according to the conditions inside the aerosol generating device.

[0042] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention. However, the present invention can be implemented in various forms and is not limited to the embodiments described herein.

[0043] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0044] Figure 1 is a diagram showing an embodiment of an aerosol generating device according to the present invention.

[0045] Reference Figure 1 The aerosol generating device 100 may include an aerosol generating article inserting portion 110, a first heating unit 120, a vaporizing unit 130, a second heating unit 135, and a control unit 140. The aerosol generating article 10 may be inserted into the aerosol generating article inserting portion 110. In the aerosol generating device 100, only components related to the present embodiment are shown. Therefore, those skilled in the art can easily understand that, in addition to the components including Figure 1 In addition to the components shown in FIG. 1 , other common components may be included in the aerosol generating device 100. In addition, the aerosol generating device 100 may be in the form of a stick or a holder.

[0046] The aerosol-generating article insertion portion 110 corresponds to an area of ​​the aerosol-generating device 100 and can provide a space into which the aerosol-generating article 10 is inserted. The aerosol-generating article 10 can have a generally known form and can have a form in which the tobacco raw material is deposited on a heat-conductive material. For example, the heat-conductive material can be a metal foil, such as an aluminum foil.

[0047] In one embodiment, the first heating unit 120 can heat the aerosol generating article 10 inserted into the aerosol generating article insertion portion 110. The heating unit 120 can be, for example, a heater module. The heater module can include a tubular heating element, a plate heating element, and a needle-shaped or rod-shaped heating element, and can heat the inside and / or outside of the aerosol generating article 10 according to the shape of the heating element. The first heating unit 120 can generate an aerosol with a tobacco flavor by heating the aerosol generating article 10. Therefore, the user can inhale the aerosol with a tobacco flavor by inhaling one end of the aerosol generating article 10 with his / or her mouth. The suction force of the user inhaling one end of the aerosol generating article 10 can be maintained within a certain range.

[0048] The vaporization unit 130 may be coupled to the aerosol generating device 100 so that the vaporization unit 130 may be replaced. The second heating unit 135 may be arranged inside the vaporization unit 130. The second heating unit 135 may be, for example, a heater module. The heater module may include a core and a vaporization unit, and the heater module may generate an aerosol by heating the aerosol generating substance absorbed through the core by means of the vaporization unit. The vaporization unit 130 may generate an aerosol by heating the aerosol generating substance stored in the vaporization unit 130 using the second heating unit 135, and the generated aerosol may be released toward the inserted aerosol generating article 10 so that the generated aerosol passes through the aerosol generating article 10 inserted into the aerosol generating article inserting portion 110. Therefore, tobacco flavor may be added to the aerosol passing through the aerosol generating article 10, and the user may inhale the aerosol having the tobacco flavor by inhaling one end of the aerosol generating article 10 with his / her mouth. Therefore, the user can inhale the aerosol generated by the vaporization unit 130 together with the aerosol generated by heating the aerosol generating article 10. In this case, the heater module can heat the aerosol generating article 10 to a relatively low temperature. For example, the heater module can heat the aerosol generating article 10 to a temperature of about 40° C. to 200° C. The vaporization unit 130 used in this application document can be used interchangeably with terms such as atomization unit, atomizer, and atomization cartridge.

[0049] The control unit 140 may control the overall operation of the aerosol generating device 100. Specifically, the control unit 140 may control the operation of the first heating unit 120, the vaporization unit 130, the second heating unit 135, and other components included in the aerosol generating device 100. In addition, the control unit 140 may confirm the state of each component of the aerosol generating device 100 and determine whether the aerosol generating device 100 is in an operable state. For example, the aerosol generating device 100 may further include a battery, and the control unit 140 may check the charging state of the battery to determine whether the aerosol generating device 100 is in an operable state. In addition, the aerosol generating device 100 may further include a display unit and a vibration generating unit, and the control unit 140 may confirm the state of the aerosol generating device 100 to operate the display unit and / or the vibration generating unit. In addition, the control unit 140 may control the operation of the components that may be included in the aerosol generating device 100.

[0050] The control unit 140 may include at least one processor. The control unit may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing a program that can be executed in the microprocessor. In addition, those skilled in the art may easily understand that the present embodiment may be implemented using other types of hardware.

[0051] Figure 2a and Figure 2b It shows that the Figure 1 Illustration of an embodiment of a vaporization unit in an aerosol generating device.

[0052] Reference Figure 1 and Figure 2a The vaporization unit 130 may include a storage unit 130a, a temperature sensor 130b, and a second heating unit 135. The storage unit 130a may provide a space in which an aerosol generating substance (AGM) is stored. The aerosol generating substance (AGM) stored in the provided space may be heated by heat provided by the second heating unit 135 and released to the aerosol generating article inserting portion 110.

[0053] The second heating unit 135 may include a vaporizer 135b and a core 135a. The core 135a may absorb the aerosol generating material (AGM) stored in the storage unit 130a. The core 135a may be made of a material that can absorb a liquid phase through a capillary shape, such as silica, cotton, or a bead polymer. However, this is an example, and the material constituting the core 135a is not limited thereto.

[0054] The vaporizer 135b may generate aerosol by vaporizing the aerosol generating material (AGM) absorbed in the core 135a. Figure 2a , the vaporizer 135b is shown as an example in which the vaporizer 135b is implemented as a heating element that vaporizes the liquid phase absorbed in the core 135a by heating, but this is an example, and the device for vaporizing the liquid phase is not limited thereto. For example, the vaporizer 135b can also be implemented in the form of vaporizing the aerosol generating material (AGM) by ultrasonic waves.

[0055] Refer to Figure 2b , when the second heating unit 135 continues to be heated in a state where the aerosol generating material (AGM) is exhausted, as the temperature of the second heating unit 135 increases, the second heating unit 135 may be damaged. Therefore, the temperature sensor 130b may determine whether the aerosol generating material (AGM) has been exhausted by detecting the temperature change of the second heating unit 135. When the temperature of the second heating unit 135 increases to above a preset temperature, the temperature sensor 130b may send a signal to the control unit 140. The control unit 140 may receive the signal and stop heating the second heating unit 135, thereby preventing the second heating unit 135 from being damaged.

[0056] In this way, when the aerosol generating material (AGM) is exhausted, the aerosol generating device 100 according to the present invention can detect the temperature change of the second heating unit 135 that heats the vaporization unit 130, and stop heating the second heating unit 135. Thereafter, smoking can be performed only by heating by the first heating unit 120. The first heating unit 120 may start heating after the second heating unit 135 stops heating, or the first heating unit 120 may increase the heating temperature after the second heating unit 135 stops heating. This will be described with reference to the drawings to be described later.

[0057] Alternatively, when the second heating unit 135 continues to heat, the temperature of the vaporizer 135b may increase, and the vaporizer 135b may be damaged. In this case, the remaining aerosol generating material (AGM) needs to be heated to a relatively low temperature. In this case, in order to maintain the user's smoking satisfaction, the amount of aerosol generated and the amount of nicotine transferred can be maintained by increasing the heating temperature of the first heating unit 120.

[0058] Figure 3 It shows that Figure 1 Illustration of the temperature range that is controlled within an aerosol generating device.

[0059] Reference Figure 1 and Figure 3, the heating temperature T1 of the first heating unit 120 and the heating temperature T2 of the second heating unit 135 can be adjusted in a manner associated with each other. As described above, when the aerosol generating material stored in the vaporizing unit 130 is used up and the temperature of the second heating unit 135 rises above the preset temperature, the aerosol generating device 100 can use only the first heating unit 120 of the first heating unit 120 and the second heating unit 135 for smoking.

[0060] In this case, the user's smoking satisfaction may be reduced because the aerosol and heat generated by the vaporization unit 130 are not released toward the aerosol-generating article 10 inserted into the aerosol-generating article insertion portion 110. Therefore, when the heating of the second heating unit 135 is stopped, the heating of the first heating unit 120 may be started, or the heating temperature of the first heating unit 120 may be increased, thereby preventing the user's smoking satisfaction from being reduced.

[0061] For example, when the heating temperature of the second heating unit 135 changes from on T2_ON to off T2_OFF, the heating temperature of the first heating unit 120 may change from off T1_OFF to on T1_ON, in which case the heating temperature of the first heating unit 120 may be heated to the first temperature range T1_R1 or the second temperature range T1_R2.

[0062] Alternatively, when the heating temperature of the second heating unit 135 is changed from on T2_ON to off T2_OFF, the heating temperature of the first heating unit 120 may be increased from the first temperature range T1_R1 to the second temperature range T1_R2.

[0063] Alternatively, the second heating unit 135 may reduce the heating temperature from the second temperature range T2_R2 to the first temperature range T2_R1. In this case, in order to compensate for the reduced aerosol generation and the heat sensation felt by the smoker, the heating temperature of the first heating unit 120 may be changed from off T1_OFF to on T1_ON, or increased from the first temperature range T1_R1 to the second temperature range T1_R2.

[0064] In this way, the aerosol generating device 100 according to the present invention can perform smoking while maintaining the smoker's smoking satisfaction without damaging the device even when the aerosol is exhausted.

[0065] Turning the first heating unit 120 off T1_OFF may mean not performing heating, heating the first heating unit 120 to the first temperature range T1_R1 may mean heating to about 120°C to 200°C, and heating the first heating unit 120 to the second temperature range T1_R2 may mean heating to about 150°C to 250°C.

[0066] In this case, the maximum temperature at which the first heating unit 120 is heated may be about 350° C., the first temperature range T1_R1 may be determined to be about 30% to 60% of the maximum temperature, and the second temperature range T1_R2 may be determined to be about 40% to 70% of the maximum temperature.

[0067] Turning off the second heating unit 135 T2_OFF may mean that the second heating unit 135 does not perform heating, heating the second heating unit 135 to the first temperature range T2_R1 may mean heating to about 150°C to 250°C, and heating the second heating unit 135 to the second temperature range T2_R2 may mean heating to about 200°C to 300°C.

[0068] In this case, the maximum temperature at which the second heating unit 135 is heated may be about 800° C., the first temperature range T2_R1 may be determined as about 15% to 30% of the maximum temperature, and the second temperature range T2_R2 may be determined as about 25% to 38% of the maximum temperature.

[0069] The temperature at which the control unit 140 determines that the temperature of the second heating unit 135 increases above the preset temperature may be about 300° C. That is, the temperature at which the control unit 140 determines that the aerosol generating material stored in the vaporizing unit 130 has been exhausted may be about 300° C.

[0070] Figure 4 1 is a diagram showing another embodiment of the aerosol generating device according to the present invention. In addition to adding a sensor 150, Figure 4 Can be used with Figure 1 Therefore, the description of the repeated configuration will be omitted.

[0071] Reference Figure 4 , the aerosol generating device 100 may further include a sensor 150. The sensor 150 may detect an external stimulus. The control unit 140 may control the operation of the aerosol generating device 100 based on the stimulus detected by the sensor 150. In one embodiment, the stimulus may be an external temperature, and the sensor 150 may include a temperature sensor for detecting the temperature.

[0072] In another embodiment, the stimulus may be a puff by the user, and the sensor 150 may include a puff detection sensor for detecting the puff by the user. The puff detection sensor may detect the number of puffs by the user.

[0073] In another embodiment, the stimulus may be a user's touch, and the sensor 150 may include a touch sensor capable of detecting the user's touch. The touch sensor may detect a microcurrent generated by the user's hand, and may also detect the pressure applied by the user's hand. The touch sensor may be a capacitive touch sensor, a resistive touch sensor, or a button touch sensor.

[0074] exist Figure 1 In the embodiment of the invention, the control unit 140 of the aerosol generating device 100 detects the temperature change of the vaporizing unit 130 to control the heating of the second heating unit 135, but in Figure 4 In an embodiment, the sensor 150 of the aerosol generating device 100 can control the heating of the second heating unit 135.

[0075] For example, after the sensor 150 detects the user's puff, when a preset number of puffs has passed, the heating of the second heating unit 135 can be stopped. In this case, the preset number of puffs can generally be set to the number of times required for the aerosol generating substance to be exhausted. Generally, when the user puffs about 280 to 310 times, the aerosol generating substance stored in the vaporizing unit 130 is completely exhausted. Therefore, the preset number of times can be freely determined between 280 and 310 times. However, this is an example, and the sensor 150 can set the preset number of puffs differently according to the amount of the aerosol generating substance.

[0076] Figure 5 1 is a diagram showing another embodiment of the aerosol generating device according to the present invention. In addition to adding a vibration generating unit 160, Figure 5 Can be used with Figure 4 Therefore, the description of the repeated configuration will be omitted.

[0077] Reference Figure 5 , the aerosol generating device 100 may further include a vibration generating unit 160. The vibration generating unit 160 may generate vibrations under the control of the control unit 140. When the temperature of the vaporizing unit 130 rises above a preset temperature, the control unit 140 may operate the vibration generating unit 160 to generate vibrations in the aerosol generating device 130. In this way, the user may recognize that the aerosol generating substance stored in the vaporizing unit 130 has been used up by applying a stimulus to the sensor 150, and stop heating the second heating unit 135. Alternatively, when the temperature of the vaporizing unit 130 rises above a preset temperature, the control unit 140 may automatically stop heating the second heating unit 135.

[0078] Thereafter, the first heating unit 120 may start heating, or a temperature range in which the first heating unit 120 performs heating may be increased.

[0079] For example, when the second heating unit 135 stops heating, the user may stimulate the sensor 150, and the first heating unit 120 may start heating by the stimulation.

[0080] Alternatively, when the second heating unit 135 stops heating, the user may stimulate the sensor 150 , and the first heating unit 120 may increase the temperature used to heat the aerosol-generating article 10 through the stimulation.

[0081] When the amount of generated aerosol increases, the user may reduce the temperature of the second heating unit 135 by stimulating the sensor 150. When the temperature of the second heating unit 135 is reduced, the amount of nicotine transferred by the aerosol-generating article 10 may be reduced. Therefore, the user may increase the temperature of the first heating unit 120 by stimulating the sensor 150.

[0082] When the sensor 150 is a touch sensor, the heating temperatures of the first heating unit 120 and the second heating unit 135 may be adjusted according to the number of times the touch sensor is touched. For example, when the user touches the touch sensor an odd number of times, the heating temperature of the second heating unit 135 may be reduced or turned off, and when the user touches the touch sensor an even number of times, the temperature of the first heating unit 120 may be increased.

[0083] Alternatively, when the user touches the touch sensor once, the temperature control of the second heating unit 135 is activated, and as the time the user touches the touch sensor increases, the heating temperature of the second heating unit 135 may be reduced and then turned off. When the user touches the touch sensor twice, the temperature control of the first heating unit 120 is activated, and as the time the user touches the touch sensor increases, the heating temperature of the first heating unit 120 may be increased.

[0084] Alternatively, the vibration generating unit 160 may generate vibration when the control unit 140 stops heating the second heating unit 135. In this case, the user may increase the heating temperature of the first heating unit 120 by touching the touch sensor. For example, as the number of times the user touches the touch sensor increases, the heating temperature of the first heating unit 120 may increase. Alternatively, as the time the user touches the touch sensor increases, the heating temperature of the first heating unit 120 may increase.

[0085] However, this is merely an example for convenience of explanation, and the temperature may be adjusted by various stimuli.In addition, in addition to the above combination, the temperature ranges of the first heating unit 120 and the second heating unit 135 may be combined in various ways.

[0086] Figure 6 1 is a diagram showing another embodiment of the aerosol generating device according to the present invention. In addition to adding a display unit 170, Figure 6 Can be used with Figure 4 Therefore, the description of the repeated configuration will be omitted.

[0087] Reference Figure 6 , the aerosol generating device 100 may further include a display unit 170. When the heating temperature of the second heating unit 135 rises above a preset temperature, the control unit 140 may operate the display unit 170 to notify the user. In this case, the control unit 140 may notify the user after automatically stopping the second heating unit 135, or may notify the user without stopping the operation of the second heating unit 135. The display unit 170 may emit light to notify the user. For example, the display unit 170 may notify the user through a static image or video. This may be operated in different ways according to the user's preference for using the aerosol generating device 100.

[0088] Figure 7 1 is a diagram showing another embodiment of the aerosol generating device according to the present invention. In addition to adding a vibration generating unit 160 and a display unit 170, Figure 7 Can be used with Figure 4 Therefore, the description of the repeated configuration will be omitted.

[0089] Reference Figure 7 , the aerosol generating device 100 may further include a vibration generating unit 160 and a display unit 170. When the heating temperature of the second heating unit 135 rises above a preset temperature, the control unit 140 may cause the vibration generating unit 160 and the display unit 170 to operate simultaneously to notify the user. In this case, the control unit 140 may notify the user after automatically stopping the second heating unit 135, or may notify the user without stopping the operation of the second heating unit 135. This may be operated in different ways according to the user's preference for using the aerosol generating device 100.

[0090] Although the present invention has been described in conjunction with the above preferred embodiments, various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, as long as these modifications and variations belong to the spirit of the present invention, these modifications and variations all fall within the scope of the claims.
