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 a device that generates an aerosol (e.g., an aerosol generating article type electronic cigarette) by electrically heating an aerosol generating article stick has been increasing. Accordingly, research on electric heating type aerosol generating devices and aerosol generating article sticks (or aerosol generating articles) applied thereto has been actively conducted.

[0004] The aerosol generating device can include a heating unit that can control 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] Thus, further research and development are needed to determine a specific method for automatically or manually controlling the heating temperature of an aerosol generator according to the internal conditions of the aerosol generator. [Prior art documents] [Patent Documents]

[0008] The present invention is the result of the aforementioned research and development, and aims to provide an aerosol generator capable of controlling the internal heating temperature based on stimuli detected by a sensor unit. [Means for solving the problem]

[0009] An aerosol generating device with controllable heating temperature according to an embodiment of the present invention for solving the above-mentioned objectives includes an aerosol generating article insertion section into which an aerosol generating article can be inserted and which includes a first heating section for applying heat to the aerosol generating article, an aerosol generating substance, a second heating section for applying heat to the aerosol generating substance, a vaporization section including a temperature sensor capable of checking the temperature of the second heating section, and a control unit capable of controlling the first heating section and the second heating section, respectively.

[0010] In this embodiment, if the temperature of the second heating section, as confirmed by the temperature sensor, rises to or above a previously set temperature, the control unit can heat only the first heating section of the two heating sections.

[0011] In this embodiment, the previously set temperature may be 300°C.

[0012] In this embodiment, the control unit can turn on the first heating unit when the temperature of the second heating unit rises to or above the previously set temperature.

[0013] In one embodiment, if the temperature of the second heating unit rises above the previously set temperature, the control unit raises the temperature of the first heating unit from the first temperature range to the second temperature range, and the second temperature range may be a temperature range higher than the first temperature range.

[0014] In this embodiment, the first temperature range may be 120°C to 200°C, and the second temperature range may be 150°C to 250°C.

[0015] In this embodiment, the system further includes a vibration generating unit that generates vibrations, and the control unit can activate the vibration generating unit when the temperature of the second heating unit rises to or above the previously set temperature.

[0016] In this embodiment, the system further includes a display unit for displaying images, and the control unit can activate the display unit when the temperature of the second heating unit rises to or above the previously set temperature.

[0017] In this embodiment, the device further includes a touch sensor that detects a user's touch, and the touch sensor can turn on the first heating unit based on the number of times the user touches the device or the duration of the touch.

[0018] In one embodiment, the system further includes a touch sensor that detects a user's touch, the touch sensor raising the temperature of the first heating unit from a first temperature range to a second temperature range based on the number of user touches or the duration of the touches, the second temperature range being a higher temperature range than the first temperature range.

[0019] In this embodiment, the control unit can lower the heating temperature of the second heating unit if the temperature of the second heating unit, as confirmed by the temperature sensor, rises above a previously set temperature.

[0020] In an embodiment, reducing the heating temperature of the second heating unit can turn off the second heating unit or reduce the heating temperature at which the second heating unit was heating.

[0021] In an embodiment, when the temperature of the second heating unit rises above the preset temperature, the control unit raises the temperature of the first heating unit. Raising the heating temperature of the first heating unit can turn on the first heating unit or further raise the heating temperature at which the first heating unit was heating.

Advantages of the Invention

[0022] The aerosol generator according to the present invention can include a first heating unit disposed in an aerosol generating article insertion part for heating an aerosol generating article and a second heating unit disposed in a vaporization part for heating an aerosol generating substance. At this time, the heating temperatures of the first heating unit and the second heating unit can be adjusted respectively, and are determined dependently on each other according to the remaining amount of the aerosol generating substance and the heating temperature range of the second heating unit, so that while maintaining the smoking satisfaction of the smoker, damage to the aerosol generator can be prevented.

[0024] The present invention will be described in more detail below.

[0025] The terminology used in these embodiments has been selected as widely used and general terms as possible, taking into account the functions of the present invention. However, this may vary depending on the intent of the articulators in the field, precedents, the emergence of new technologies, etc. In certain cases, the applicant may have arbitrarily selected terms, in which case their meaning will be described in detail in the relevant section of the invention description. Therefore, the terminology used in this invention should not be merely names of terms, but should be defined based on the meaning of the term and the overall content of the present invention.

[0026] When a specification states that a part "includes" a component, unless otherwise specified, this does not mean that other components are excluded, but rather that other components may be included. Furthermore, terms such as "...part" and "...module" used in the specification refer to a unit that processes at least one function or operation, which can be embodied in hardware or software, or in a combination of hardware and software.

[0027] Throughout this specification, “aerosol-generating substance” means a substance capable of generating an aerosol, and may also mean an aerosol-forming substrate. The aerosol may include volatile compounds. The aerosol-generating substance may be a solid or a liquid.

[0028] For example, solid aerosol-producing substances may include solid materials based on tobacco raw materials such as flat tobacco leaves, shredded tobacco, and reconstituted tobacco, and liquid aerosol-producing substances may include liquid materials based on nicotine, tobacco extracts, and various flavoring agents. Of course, the examples given above are not the only ones.

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

[0030] Throughout this specification, “puff” means the user’s inhalation, and “inhalation” can mean the act of drawing something into the user’s mouth, nose, or lungs through the user’s mouth or nose.

[0031] Embodiments of the present invention will be described in detail below with reference to the attached drawings, so that they can be easily implemented by a person with ordinary skill in the art to which the present invention pertains. However, the present invention can be embodied in a variety of different forms and is not limited to the embodiments described herein.

[0032] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0033] Figure 1 shows one embodiment of the aerosol generating device according to the present invention.

[0034] Referring to Figure 1, the aerosol generator (100) may include an aerosol generating article insertion section (110), a first heating section (120), a vaporization section (130), a second heating section (135), and a control section (140). An aerosol generating article (10) can be inserted into the aerosol generating article insertion section (110). Only the components of the aerosol generator (100) relevant to this embodiment are shown. Therefore, it will be easily understood by a person with ordinary skill in the art related to this embodiment that the aerosol generator (100) may further include other general-purpose components in addition to those shown in Figure 1. Furthermore, the aerosol generator (100) may be in the form of a stick or a holder.

[0035] The aerosol generating article insertion section (110) corresponds to an area 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 any currently known common form, and can have a form in which tobacco raw materials are stacked on a heat conductive material. For example, the heat conductive material may be a metal foil such as aluminum foil.

[0036] In one embodiment, the first heating unit (120) can heat the aerosol generating article (10) inserted into the aerosol generating article insertion unit (110). The first heating unit (120) may be, for example, a heater module. The heater module may include tubular heating elements, plate heating elements, needle or rod-shaped heating elements, and depending on the shape of the heating elements, it can heat the inside and / or outside of the aerosol generating article (10). The first heating unit (120) can heat the aerosol generating article (10) to generate an aerosol flavored with tobacco, so that the user can inhale the tobacco-flavored aerosol by inhaling one end of the aerosol generating article (10) with their mouth. The inhalation force with which 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 generator (100) in a replaceable manner. A second heating unit (135) may be located 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 unit, and the heater module can heat the aerosol-generating material absorbed through the wick through the vaporization unit to generate an aerosol. The vaporization unit (130) can heat the aerosol-generating material stored inside using the second heating unit (135) to generate an aerosol, and can release the generated aerosol towards the inserted aerosol-generating article (10) so that the generated aerosol passes through the inserted aerosol-generating article (10) in the aerosol-generating article insertion unit (110). Therefore, tobacco flavor can be added to the aerosol that has passed through the aerosol generating article (10), and the user can inhale the tobacco-flavored aerosol by inhaling one end of the aerosol generating article (10) with their mouth. Thus, 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. The term vaporization unit (130) as used herein may be used interchangeably with terms such as atomizer, cartomizer, etc.

[0038] The control unit (140) can control the overall operation of the aerosol generator (100). Specifically, the control unit (140) can control the operation of not only the first heating unit (120), the vaporization unit (130), and the second heating unit (135), but also other components included in the aerosol generator (100). The control unit (140) can also check the state of each component of the aerosol generator (100) and determine whether the aerosol generator (100) is operational. For example, the aerosol generator (100) may 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 operational. The aerosol generator (100) may 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 activate the display unit and / or the vibration generating unit. In addition, the control unit (140) can control the operation of components that can be included in the aerosol generator (100).

[0039] The control unit (140) may include at least one processor. The processor may be implemented as an array of numerous logic gates, or as a combination of a general-purpose microprocessor and memory in which a program that can be executed by this microprocessor is stored. It will also be readily apparent to those ordinary skill in the art to which this embodiment belongs that it may be implemented as other forms of hardware.

[0040] Figures 2a and 2b show one embodiment of the vaporization section included in the aerosol generator shown in Figure 1.

[0041] Referring to Figures 1 and 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) can provide a space for storing aerosol generating material (AGM). The aerosol generating material (AGM) stored in the provided space can be heated by the heat provided by the second heating unit (135) and released into the aerosol generating article insertion unit (110).

[0042] The second heating section (135) may include a vaporization section (135b) and a wick (135a). The wick (135a) can absorb the aerosol-generating substance (AGM) stored in the storage section (130a). The wick (135a) can be made of a material that can absorb the liquid phase through a capillary structure, such as silica, cotton, or a bead aggregate. However, this is illustrative, and the material constituting the wick (135a) is not limited thereto.

[0043] The vaporization unit (135b) can vaporize the aerosol-generating substance (AGM) absorbed by the wick (135a) and generate an aerosol. In Figure 2a, the vaporization unit (135b) is illustrated as an example in which it is embodied as a heating element that vaporizes the liquid phase absorbed by the wick (135a) through heating, but this is illustrative and the means of vaporizing the liquid phase are not limited to this. For example, the vaporization unit (135b) can also be embodied in a form that vaporizes the aerosol-generating substance (AGM) through ultrasound.

[0044] Referring to Figure 2b, if the second heating unit (135) continues to be heated after all of the aerosol generating material (AGM) has been consumed, damage to the second heating unit (135) may occur as its temperature rises. Therefore, the temperature sensor (130b) can detect the temperature change of the second heating unit (135) and determine whether all of the aerosol generating material (AGM) has been consumed. If the temperature of the second heating unit (135) rises above a previously set 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 damage to the second heating unit (135).

[0045] Thus, the aerosol generator (100) according to the present invention can detect the temperature change of the second heating unit (135) that heats the vaporization unit (130) when all of the aerosol generating substance (AGM) has been consumed, and can stop heating the second heating unit (135). After this, smoking can be performed using only the heating of the first heating unit (120). The first heating unit (120) can start heating after the heating of the second heating unit (135) has been interrupted, or it can raise the temperature that was being heated after the heating of the second heating unit (135) was interrupted. This will be explained with reference to the figures described later.

[0046] Alternatively, if the second heating section (135) continues heating, the temperature of the vaporization section (135b) may rise, potentially causing damage to the vaporization section (135b). In this case, it is necessary to heat the remaining aerosol generating material (AGM) at a relatively lower temperature. At this time, in order to maintain user satisfaction with smoking, the amount of aerosol generated and the amount of nicotine transferred can be maintained by increasing the heating temperature of the first heating section (120).

[0047] Figure 3 shows the temperature range that can be controlled within the aerosol generator shown in Figure 1.

[0048] Referring to Figures 1 and 3, the heating temperature (T1) of the first heating section (120) and the heating temperature (T2) of the second heating section (135) can be adjusted dependently to each other. As described above, when all the aerosol generating material stored in the vaporization section (130) is consumed and the temperature of the second heating section (135) rises above the previously set temperature, the aerosol generator (100) can perform smoking using only the first heating section (120) of the two heating sections (135).

[0049] In such a case, the aerosol and heat generated in the vaporization section (130) are not released toward the aerosol generating article (10) inserted into the aerosol generating article insertion section (110), which may reduce the user's smoking satisfaction. Therefore, if heating of the second heating section (135) is stopped, the user's smoking satisfaction can be prevented by starting heating of the first heating section (120) or by increasing the heating temperature of the first heating section (120).

[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 be set to either the first temperature range (T1_R1) or the second temperature range (T1_R2).

[0051] Alternatively, if 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 increase from the first temperature range (T1_R1) to the second temperature range (T1_R2).

[0052] Alternatively, the second heating unit (135) can lower its heating temperature from the second temperature range (T2_R2) to the first temperature range (T2_R1). In this case, to compensate for the reduced amount of aerosol generated and the increased 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 raised from the first temperature range (T1_R1) to the second temperature range (T1_R2).

[0053] Thus, the aerosol generator (100) according to the present invention allows smokers to continue smoking while maintaining their smoking satisfaction without damaging the device, even when all the aerosols have been consumed.

[0054] When the first heating unit (120) is turned off (T1_OFF), it can mean that no heating is performed. When the first heating unit (120) is heated to a first temperature range (T1_R1), it can mean that it is heated to approximately 120°C to 200°C. When the first heating unit (120) is heated to a second temperature range (T1_R2), it can mean that it is heated to approximately 150°C to 250°C.

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

[0056] When the second heating unit (135) is turned off (T2_OFF), it can be said that the second heating unit (135) does not perform heating. When the second heating unit (135) is heated to the first temperature range (T2_R1), it can be said that it is heated to approximately 150°C to 250°C. When the second heating unit (135) is heated to the second temperature range (T2_R2), it can be said that it is heated to approximately 200°C to 300°C.

[0057] At this time, the maximum temperature at which the second heating section (135) is heated is approximately 800°C, and the first temperature range (T2_R1) can be set to approximately 15% to 30% of the maximum temperature, while the second temperature range (T2_R2) can be set to approximately 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 a previously set temperature may be approximately 300°C. In other words, the temperature at which the control unit (140) determines that all of the aerosol-generating material stored in the vaporization unit (130) has been used may be approximately 300°C.

[0059] Figure 4 shows another embodiment of the aerosol generator according to the present invention. Figure 4 may be substantially the same as Figure 1, except that a sensor (150) has been added. Therefore, a description of the redundant configuration is omitted.

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

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

[0062] 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 be capable of detecting minute currents generated from the user's hand and may also be capable of detecting pressure applied by the user's hand. The touch sensor may be a capacitive touch sensor, a pressure-sensitive touch sensor, or a button-type touch sensor.

[0063] In the embodiment shown in Figure 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 shown in Figure 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) detects the user's puff, heating of the second heating unit (135) can be interrupted once a predetermined number of puffs has elapsed. At this time, the predetermined number of puffs can usually be set to the number of times it takes to consume all of the aerosol generating substance. Typically, if the user takes about 280 to 310 puffs, all of the aerosol generating substance stored in the vaporization unit (130) will be consumed. Therefore, the predetermined number can be freely determined between 280 and 310 puffs. However, this is an example, and the sensor (150) can also change the predetermined number of puffs depending on the amount of aerosol generating substance.

[0065] Figure 5 shows yet another embodiment of the aerosol generator according to the present invention. Figure 5 may be substantially the same as Figure 4, except that a vibration generating unit (160) has been added. Therefore, a description of the redundant configuration will be omitted.

[0066] Referring to Figure 5, the aerosol generator (100) may 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 vaporization unit (130) rises above a predetermined temperature, the control unit (140) can activate the vibration generating unit (160) to generate vibrations in the aerosol generator (130). This allows the user to recognize that all the aerosol generating material stored in the vaporization unit (130) has been consumed and to stimulate the sensor (150) to interrupt heating of the second heating unit (135). Alternatively, the control unit (140) can automatically interrupt heating of the second heating unit (135) when the temperature of the vaporization unit (130) rises above a predetermined temperature.

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

[0068] For example, if heating of the second heating unit (135) is interrupted, the user can stimulate the sensor (150), which will cause the first heating unit (120) to start heating.

[0069] Alternatively, if heating of the second heating unit (135) is interrupted, the user can stimulate the sensor (150), which will cause the first heating unit (120) to raise the temperature at which it heats the aerosol generating article (10).

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

[0071] If 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, if 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 if the user touches the touch sensor an even number of times, the temperature of the first heating unit (120) can be raised.

[0072] Alternatively, if the user touches the touch sensor once, the temperature control of the second heating unit (135) is activated, and the longer the user touches the touch sensor, the lower the heating temperature of the second heating unit (135) becomes, and it may eventually turn off. If the user touches the touch sensor twice, the temperature control of the first heating unit (120) is activated, and the longer the user touches the touch sensor, the higher the heating temperature of the first heating unit (120) becomes.

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

[0074] However, this is merely an illustrative example for the sake of explanation, and the temperature can be adjusted by various stimuli. Furthermore, the temperature ranges of the first heating section (120) and the second heating section (135) can be combined in many ways other than those mentioned above.

[0075] Figure 6 shows yet another embodiment of the aerosol generator according to the present invention. Figure 6 may be substantially the same as Figure 4, except that a display unit (170) has been added. Therefore, a description of the redundant configuration will be omitted.

[0076] Referring to Figure 6, the aerosol generator (100) may further include a display unit (170). The control unit (140) can activate the display unit (170) to notify the user when the heating temperature of the second heating unit (135) rises above a predetermined temperature. At this time, the control unit (140) can notify the user after the second heating unit (135) has automatically stopped, or it can notify the user while the second heating unit (135) is still operating. The display unit (170) can notify the user by emitting light. For example, the display unit (170) can notify the user through still images or moving images. This can be operated differently depending on the user's preference when using the aerosol generator (100).

[0077] Figure 7 shows yet another embodiment of the aerosol generator according to the present invention. Figure 7 may be substantially the same as Figure 4, except that a vibration generating unit (160) and a display unit (170) have been added. Therefore, a description of the redundant configuration will be omitted.

[0078] Referring to Figure 7, the aerosol generator (100) may further include a vibration generating unit (160) and a display unit (170). The control unit (140) can simultaneously activate the vibration generating unit (160) and the display unit (170) to notify the user if the heating temperature of the second heating unit (135) rises above a previously set temperature. At this time, the control unit (140) can notify the user after the second heating unit (135) has automatically stopped, or it can notify the user while the second heating unit (135) is still operating. This can be operated differently depending on the user's preference when using the aerosol generator (100).

[0079] Even if the present invention is described in relation to the preferred embodiments described above, various modifications and variations are possible without departing from the spirit and scope of the invention. Accordingly, the appended claims include such modifications and variations, insofar as they fall within the spirit of the invention. [Explanation of Symbols]
