Description

Technical Field

[0001] The present invention relates to an aerosol generating device. Specifically, the present invention relates to an aerosol generating device capable of controlling the heating temperature.

[0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2022-0096634 filed on August 3, 2022, and includes all the contents disclosed in the document of the Korean patent application as part of this specification.

Background Art

[0003] In recent years, the demand for alternative smoking articles that overcome the drawbacks of traditional aerosol generating articles has been increasing. For example, the demand for devices that generate aerosol by electrically heating an aerosol generating article stick (for example, an aerosol generating article type electronic cigarette) has been increasing. Accordingly, research on electrically heated aerosol generating devices and aerosol generating article sticks (or aerosol generating articles) applied thereto has been actively conducted.

[0004] The aerosol generating device may include a heating unit capable of controlling the heating temperature inside the device. The heating unit can also control the heating temperature for heating the aerosol generating article and can also control the heating temperature for heating the vaporization unit. At this time, the heating unit can control the heating temperature inside the aerosol generating device according to the preference of the user using the aerosol generating device. Or, the heating unit can control the heating temperature under various conditions according to the conditions inside the aerosol generating device.

[0005] For example, the vaporization unit contains an aerosol generating substance, and the heating unit can apply heat to the aerosol generating substance to release the aerosol generating substance. Even when all the aerosol generating substance in the vaporization unit is consumed, if the heating unit continues to heat inside the vaporization unit, there is a possibility of damage to the heating unit disposed inside the vaporization unit.

[0006] At present, further research and development are needed on specific methods for automatically or manually controlling the heating temperature of the aerosol generator according to the conditions inside the aerosol generator.

[0024] Hereinafter, the present invention will be described in more detail.

[0025] In the embodiments, the terms used are, as much as possible, general terms that are currently widely used while taking into account the functions in the present invention. However, this may vary depending on the intentions or precedents of those skilled in the art, the emergence of new technologies, etc. In addition, in certain cases, there are terms arbitrarily selected by the applicant, and in this case, the meaning thereof will be described in detail in the description of the corresponding invention. Therefore, the terms used in the present invention should be defined based not only on the name of the term but also on the meaning of the term and the overall content of the present invention.

[0026] Throughout the specification, when a certain part "includes" a certain component, this means that, unless otherwise stated, it does not exclude other components, but can further include other components. Also, terms such as "part" and "module" described in the specification mean a unit that processes at least one function or operation, and this can be embodied in hardware or software, or in a combination of hardware and software.

[0027] Throughout the specification, "aerosol product substance" means a substance that can generate an aerosol, and can also mean an aerosol-forming substrate. The aerosol can contain volatile compounds. The aerosol product substance may be solid or liquid.

[0028] For example, the solid aerosol product substance can include a solid substance based on tobacco raw materials such as plate-shaped leaf tobacco, shredded tobacco, and reconstituted tobacco, and the liquid aerosol product substance can include a liquid substance based on nicotine, tobacco extracts, and various flavoring agents. Of course, it is not limited to the above examples.

[0029] Throughout the specification, the aerosol generating device can be a device that generates an aerosol using an aerosol product substance in order to generate an aerosol that can be directly inhaled into the user's lungs through the user's mouth. For example, the aerosol generating device can be a holder.

[0030] Throughout the specification, "puff" means the user's inhalation, and inhalation can mean the situation of drawing in through the user's mouth or nose into the user's oral cavity, nasal cavity, or lungs.

[0031] With reference to the drawings attached below, embodiments of the present invention will be described in detail so that those with ordinary knowledge in the technical field to which the present invention pertains can easily implement them. However, the present invention can be embodied in various different forms and is not limited to the embodiments described herein.

[0032] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0033] FIG. 1 is a diagram showing an embodiment of an aerosol generating device according to the present invention.

[0034] Referring to FIG. 1, the aerosol generating device (100) can include an aerosol generating article insertion part (110), a first heating part (120), a vaporization part (130), a second heating part (135), and a control part (140). An aerosol generating article (10) can be inserted into the aerosol generating article insertion part (110). Only the components related to this embodiment are shown in the aerosol generating device (100). Therefore, those with ordinary knowledge in the technical field related to this embodiment can easily understand that other general-purpose components can be further included in the aerosol generating device (100) in addition to the components shown in FIG. 1. Also, the aerosol generating device (100) may be in a stick shape or a holder shape.

[0035] The aerosol generating article insertion part (110) corresponds to a region at one end 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 currently, and can have a form in which tobacco raw materials are stacked on a heat conductive material. For example, the heat conductive material can be a metal foil such as aluminum foil.

[0036] In one embodiment, the first heating part (120) can heat the aerosol generating article (10) inserted into the aerosol generating article insertion part (110). The first heating part (120) can be, for example, a heater module. The heater module may include a tubular heating element, a plate-shaped heating element, a needle or a 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 part (120) can heat the aerosol generating article (10) to generate an aerosol with a tobacco flavor added. Thus, the user can inhale the aerosol with a tobacco flavor added by inhaling one end of the aerosol generating article (10) with the mouth. The inhalation force when the user inhales one end of the aerosol generating article (10) can be maintained within a certain range.

[0037] The vaporization unit (130) may be coupled to the aerosol generating device (100) so as to be interchangeable. A second heating unit (135) can be disposed inside the vaporization unit (130). The second heating unit (135) may be, for example, a heater module. The heater module may include a wick and a vaporization part. The heater module can heat the aerosol generating substance absorbed through the wick through the vaporization part to generate an aerosol. The vaporization unit (130) can heat the aerosol generating substance stored inside using the second heating unit (135) to generate an aerosol, and the generated aerosol can be discharged toward the inserted aerosol generating article (10) so as to pass through the aerosol generating article (10) inserted into the aerosol generating article insertion part (110). Accordingly, a tobacco flavor can be added to the aerosol that has passed through the aerosol generating article (10), and the user can inhale through the mouth one end of the aerosol generating article (10) to inhale the aerosol with the tobacco flavor added. Accordingly, the user can inhale both the aerosol generated by the vaporization unit (130) and the aerosol generated from the heating of the aerosol generating article (10). At this time, the heater module can heat the aerosol generating article (10) at a relatively low temperature. For example, the heater module can heat the aerosol generating article (10) at a temperature of about 40°C to 200°C. As used herein, the vaporization unit (130) can be used interchangeably with terms such as an atomization unit, an atomizer, and a cartomizer.

[0038] The control unit (140) can generally control the operation of the aerosol generator (100). Specifically, the control unit (140) can control not only the first heating unit (120), the vaporization unit (130), and the second heating unit (135), but also the operations of other components included in the aerosol generator (100). In addition, the control unit (140) can check the states of the respective components of the aerosol generator (100) and determine whether the aerosol generator (100) is in an operable state. For example, the aerosol generator (100) can further include a battery, and the control unit (140) can check the charge state of the battery and determine whether the aerosol generator (100) is in an operable state. Also, the aerosol generator (100) can further include a display unit and a vibration generating unit, and the control unit (140) can check the state of the aerosol generator (100) and operate the display unit and / or the vibration generating unit. In addition to this, the control unit (140) can control the operations of the components that can be included in the aerosol generator (100).

[0039] The control unit (140) can include at least one processor. The processor can also be implemented as an array of a number of logic gates, or can be implemented as a combination of a general-purpose microprocessor and a memory in which a program that can be executed by the microprocessor is stored. Also, those having ordinary knowledge in the technical field to which the present embodiment belongs can easily understand that it can also be implemented in other forms of hardware.

[0040] FIG. 2a and FIG. 2b are diagrams showing an embodiment of the vaporization unit included in the aerosol generator of FIG. 1.

[0041] Referring to FIGS. 1 and 2a, the vaporization unit (130) can include a storage unit (130a), a temperature sensor (130b), and a second heating unit (135). The storage unit (130a) can provide a space for storing the aerosol generating material (AGM). The aerosol generating material (AGM) stored in the provided space can be heated by the heat provided from the second heating unit (135) and released to the aerosol generating article insertion unit (110).

[0042] The second heating unit (135) can include a vaporization part (135b) and a wick (135a). The wick (135a) can absorb the aerosol generating material (AGM) stored in the storage unit (130a). The wick (135a) can be embodied with a material that can absorb the liquid phase through a capillary shape such as silica, cotton, an aggregate of beads, etc. However, this is exemplary, and the material constituting the wick (135a) is not limited thereto.

[0043] The vaporization part (135b) can vaporize the aerosol generating material (AGM) absorbed by the wick (135a) to generate an aerosol. In FIG. 2a, an example is illustrated in which the vaporization part (135b) is embodied as a heating element that vaporizes the liquid phase absorbed by the wick (135a) through heating, but this is exemplary, and the means for vaporizing the liquid phase is not limited thereto. For example, the vaporization part (135b) can also be embodied in a form that vaporizes the aerosol generating material (AGM) through ultrasonic waves.

[0044] Referring to both FIGS. 2b, when the second heating unit (135) continues to be heated after all the aerosol generating material (AGM) has been consumed, there is a possibility that the second heating unit (135) may be damaged as its temperature rises. Therefore, the temperature sensor (130b) can grasp the temperature change of the second heating unit (135) and determine whether all the aerosol generating material (AGM) has been consumed. When the temperature of the second heating unit (135) rises above a preset temperature, the temperature sensor (130b) can transmit a signal to the control unit (140). Upon receiving the signal, the control unit (140) can interrupt the heating of the second heating unit (135), thereby preventing the second heating unit (135) from being damaged.

[0045] Thus, the aerosol generator (100) according to the present invention can grasp the temperature change of the second heating unit (135) that heats the vaporization unit (130) when all the aerosol generating material (AGM) has been consumed, and stop the heating of the second heating unit (135). After that, smoking can be carried out only by heating the first heating unit (120). The first heating unit (120) can start heating after the heating of the second heating unit (135) is interrupted, or increase the temperature at which it was heating after the heating of the second heating unit (135) is interrupted. This will be described with reference to the figures described later.

[0046] Alternatively, if the second heating unit (135) continues to heat, the temperature of the vaporization unit (135b) may rise, and there is a possibility that the vaporization unit (135b) may be damaged. In this case, it is necessary to heat the remaining aerosol generating material (AGM) at a relatively low temperature. At this time, in order to maintain the user's smoking satisfaction, the generation amount of aerosol and the nicotine transfer amount can be maintained by increasing the heating temperature of the first heating unit (120).

[0047] FIG. 3 is a diagram showing the temperature range adjusted within the aerosol generator of FIG. 1.

[0048] Referring to FIGS. 1 and 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 dependently on each other. As described above, when all of the aerosol generating substances stored in the vaporization unit (130) are consumed and the temperature of the second heating unit (135) rises above the preset temperature, the aerosol generating device (100) can perform smoking using only the first heating unit (120) among the first heating unit (120) and the second heating unit (135).

[0049] In such a case, since the aerosol and heat generated in the vaporization unit (130) are not released toward the aerosol generating article (10) inserted into the aerosol generating article insertion unit (110), the smoking satisfaction of the user may decrease. Therefore, when the heating of the second heating unit (135) is stopped, the heating of the first heating unit (120) can be started or the heating temperature of the first heating unit (120) can be increased to prevent the smoking satisfaction of the user from decreasing.

[0050] 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) can be changed from off (T1_OFF) to on (T1_ON). At this time, the heating temperature of the first heating unit (120) can also be heated to the first temperature range (T1_R1) or can be heated to the second temperature range (T1_R2).

[0051] Alternatively, 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) can be increased from the first temperature range (T1_R1) to the second temperature range (T1_R2).

[0052] Alternatively, the second heating unit (135) can lower 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 decreasing aerosol generation amount and the heat sensation felt by the smoker, the heating temperature of the first heating unit (120) can 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).

[0053] Thus, 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 all the aerosol is consumed.

[0054] The first heating unit (120) being off (T1_OFF) can mean that heating is not performed, and the first heating unit (120) being heated in the first temperature range (T1_R1) can mean that it is heated to about 120°C to 200°C, and the first heating unit (120) being heated in the second temperature range (T1_R2) can mean that it is heated to about 150°C to 250°C.

[0055] At this time, the maximum temperature at which the first heating unit (120) is heated is about 350°C, the first temperature range (T1_R1) can be determined to be about 30% to 60% of the maximum temperature, and the second temperature range (T1_R2) can also be determined to be about 40% to 70% of the maximum temperature.

[0056] The second heating unit (135) being off (T2_OFF) can mean that the second heating unit (135) does not perform heating, and the second heating unit (135) being heated in the first temperature range (T2_R1) can mean that it is heated to about 150°C to 250°C, and the second heating unit (135) being heated in the second temperature range (T2_R2) can mean that it is heated to about 200°C to 300°C.

[0057] At this time, the maximum temperature at which the second heating unit (135) is heated is about 800°C. The first temperature range (T2_R1) is determined to be about 15% to 30% of the maximum temperature, and the second temperature range (T2_R2) can also be determined to be about 25% to 38% of the maximum temperature.

[0058] The temperature at which the control unit (140) determines that the temperature of the second heating unit (135) has risen above the preset temperature can be about 300°C. That is, the temperature at which the control unit (140) determines that all the aerosol generating substances stored in the vaporization unit (130) have been used can be about 300°C.

[0059] FIG. 4 is a diagram showing another embodiment of the aerosol generating device according to the present invention. FIG. 4 can be substantially the same as FIG. 1 except that a sensor (150) is added. Therefore, the description of overlapping configurations will be omitted.

[0060] Referring to FIG. 4, the aerosol generating device (100) can further include a sensor (150). The sensor (150) can sense an external stimulus. Based on the stimulus sensed by the sensor (150), the control unit (140) can control the operation of the aerosol generating device (100). In one embodiment, the stimulus can be an external temperature, and the sensor (150) can include a temperature sensor for sensing the temperature.

[0061] In another embodiment, the stimulus can be a user's puff, and the sensor (150) can include a puff sensing sensor for sensing the user's puff. The puff sensing sensor can sense the number of times of the user's puff.

[0062] In another embodiment, the stimulus may be a touch of the user, and the sensor (150) may include a touch sensor capable of sensing the touch of the user. The touch sensor can sense a minute current generated from the user's hand and can also sense the pressure applied by the user's hand. The touch sensor may be a capacitance type touch sensor, a pressure sensitive touch sensor, or a button type touch sensor.

[0063] In the embodiment of FIG. 1, the control unit (140) of the aerosol generator (100) senses the temperature change of the vaporization unit (130) and controls the heating of the second heating unit (135). However, in the embodiment of FIG. 4, the heating of the second heating unit (135) can be controlled by the sensor (150) of the aerosol generator (100).

[0064] For example, after the sensor (150) senses the puffs of the user, if the number of preset puffs has passed, the heating of the second heating unit (135) can be interrupted. At this time, the number of preset puffs can usually be set to the number of times required to consume all the aerosol generating substances. Usually, when the user takes about 280 to 310 puffs, all the aerosol generating substances stored in the vaporization unit (130) will be consumed. Therefore, the preset number can be freely determined between 280 and 310 times. However, this is exemplary, and the sensor (150) can also set the number of preset puffs to vary according to the amount of the aerosol generating substance.

[0065] FIG. 5 is a diagram showing another embodiment of the aerosol generator according to the present invention. FIG. 5 may be substantially the same as FIG. 4 except that a vibration generating unit (160) is added. Therefore, the description of overlapping configurations is omitted.

[0066] Referring to FIG. 5, the aerosol generating device (100) can further include a vibration generating unit (160). The vibration generating unit (160) can 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) can activate the vibration generating unit (160) to generate vibrations in the aerosol generating device (130). Thereby, the user can recognize that all the aerosol generating substances stored in the vaporizing unit (130) have been consumed, stimulate the sensor (150), and interrupt the heating of the second heating unit (135). Alternatively, when the temperature of the vaporizing unit (130) rises above a preset temperature, the control unit (140) can automatically interrupt the heating of the second heating unit (135).

[0067] After that, the first heating unit (120) may start heating, or the temperature range at which the first heating unit (120) was heating may increase.

[0068] For example, when the heating of the second heating unit (135) is interrupted, the user can stimulate the sensor (150), and by the stimulation, the first heating unit (120) can start heating.

[0069] Alternatively, when the heating of the second heating unit (135) is interrupted, the user can stimulate the sensor (150), and by the stimulation, the first heating unit (120) can increase the temperature at which it heats the aerosol generating article (10).

[0070] When the amount of aerosol generated increases, the user can stimulate the sensor (150) to lower the temperature of the second heating unit (135). When the temperature of the second heating unit (135) decreases, the amount of nicotine transfer through the aerosol generating article (10) may decrease. Therefore, the user can stimulate the sensor (150) to increase the temperature of the first heating unit (120).

[0071] When the sensor (150) is a touch sensor, the heating temperatures of the first heating unit (120) and the second heating unit (135) can 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) can be lowered or turned off, and when the user touches the touch sensor an even number of times, the temperature of the first heating unit (120) can be raised.

[0072] Alternatively, when the user touches the touch sensor once, the temperature adjustment of the second heating unit (135) is activated, and the longer the time the user touches the touch sensor, the lower the heating temperature of the second heating unit (135) can become and it can disappear. When the user touches the touch sensor twice, the temperature adjustment of the first heating unit (120) is activated, and the longer the time the user touches the touch sensor, the higher the heating temperature of the first heating unit (120) can become.

[0073] Alternatively, the vibration generating unit (160) can generate vibration when the control unit (140) interrupts the heating of the second heating unit (135). At this time, the user can raise the heating temperature of the first heating unit (120) by touching the touch sensor. For example, the higher the number of times the user touches the touch sensor, the higher the heating temperature of the first heating unit (120) can become. Or, the longer the time the user touches the touch sensor, the higher the heating temperature of the first heating unit (120) can become.

[0074] However, this is only an exemplary explanation for the convenience of description, and the temperature can be adjusted by various stimuli. Also, the combination of the temperature ranges of the first heating unit (120) and the second heating unit (135) can be combined in various ways other than the aforementioned combination.

[0075] FIG. 6 is a diagram showing another embodiment of the aerosol generator according to the present invention. FIG. 6 may be substantially the same as FIG. 4 except that a display unit (170) is added. Therefore, the description of overlapping configurations will be omitted.

[0076] Referring to FIG. 6, the aerosol generator (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) can activate the display unit (170) to notify the user. At this time, the control unit (140) can also notify the user after the automatic stop of the second heating unit (135), or can notify the user without stopping the operation of the second heating unit (135). The display unit (170) can notify the user by emitting light. For example, the display unit (170) can notify the user through a still image or a moving image. This can be operated differently according to the preference of the user using the aerosol generator (100).

[0077] FIG. 7 is a diagram showing another embodiment of the aerosol generator according to the present invention. FIG. 7 may be substantially the same as FIG. 4 except that a vibration generating unit (160) and a display unit (170) are added. Therefore, the description of overlapping configurations will be omitted.

[0078] Referring to FIG. 7, the aerosol generator (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) can simultaneously activate the vibration generating unit (160) and the display unit (170) to notify the user. At this time, the control unit (140) can also notify the user after the automatic stop of the second heating unit (135), or can notify the user without stopping the operation of the second heating unit (135). This can be operated differently according to the preference of the user using the aerosol generator (100).

[0079] Even if the present invention has been described in connection with the foregoing preferred embodiments, various modifications and variations can be made without departing from the spirit and scope of the invention. Accordingly, the appended claims cover such modifications and variations as long as they fall within the spirit of the invention.
