Description

Technical Field

[0001] The various embodiments described in this disclosure relate to an aerosol generation apparatus including a sensor module. Background Technology

[0002] Recently, there has been a growing demand for alternatives to overcome the shortcomings of traditional cigarettes. For example, there is an increasing need for devices that generate aerosols by electrically heating a cigarette stick (e.g., cigarette-type electronic cigarettes). Research on cigarette sticks (or aerosol-generating products) and electrically heated aerosol-generating devices inserted into cigarette sticks has also become active.

[0003] The above-mentioned background technology was acquired or learned by the inventors during the development of this invention, and should not be construed as necessarily being a generally known technology disclosed before the application for this invention. Summary of the Invention

[0004] Technical problems to be solved The aerosol generating device can be used with various types of aerosol generating articles inserted therein. Aerosol generating articles can include aerosol generating materials, such as cigarettes, sticks, capsules, liquid materials, or cartridges.

[0005] Aerosol generating devices can identify information about aerosol-generating products and generate aerosols based on that information. For example, an aerosol generating device can control the drive state of the heater based on information about the inserted cigarette rod, thereby providing a temperature profile suitable for a single cigarette rod.

[0006] When the aerosol generating device cannot automatically identify the information of the aerosol generated article, the user must manually enter the type of the inserted aerosol generated article, which is very inconvenient. Furthermore, there are various difficulties in creating labels to identify the information of each aerosol generated article, and in some cases, the recognition accuracy of the aerosol generating device can decrease due to different recognition methods.

[0007] Technical methods for solving problems An aerosol generating apparatus according to one embodiment may include: a housing comprising a cavity for inserting an aerosol generating article; a sensor module disposed within the cavity; at least one processor receiving detection results from the sensor module; and a memory operatively connected to the at least one processor and storing executable instructions. In one embodiment, the sensor module may include: a light-emitting unit emitting light of a first wavelength into the cavity; and a light-receiving unit receiving light emitted from the aerosol generating article. In one embodiment, the at least one processor, by executing instructions stored in the memory, can identify identification information about the aerosol generating article based on the amount of light of a second wavelength different from the first wavelength.

[0008] Alternatively, an aerosol generating apparatus according to one embodiment may include: a housing comprising a cavity for inserting an aerosol generating article; a sensor module disposed within the cavity; at least one processor receiving detection results from the sensor module; and a memory operatively connected to the at least one processor and storing executable instructions. In one embodiment, the sensor module may include: a light-emitting unit emitting light of a first wavelength into the cavity; a light-receiving unit receiving light emitted from the aerosol generating article; and a filter filtering the first wavelength of light from the light received by the light-receiving unit. In one embodiment, the at least one processor, by executing instructions stored in the memory, can identify identification information about the aerosol generating article based on the amount of light filtered by the filter.

[0009] Invention Effects According to one embodiment, an aerosol generating apparatus including a sensor module can identify information about an inserted aerosol generating article (e.g., a cigarette, a cigarette stick, a capsule, or a cartridge) based on the amount of light transmitted to a light receiving unit at a specific wavelength.

[0010] Furthermore, the aerosol generating apparatus including a sensor module according to one embodiment can leverage the design advantages of the control unit and improve the accuracy of optical recognition. Additionally, the manufacturing difficulty of the aerosol generating apparatus according to one embodiment and the identification mark of the aerosol-generated article inserted therein can also be improved.

[0034] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0035] Figure 1 and Figure 2 The accompanying drawing shows an example of inserting a cigarette into an aerosol generating device.

[0036] Reference Figure 1 and Figure 2 According to one embodiment, the aerosol generating apparatus 1 may include a battery 11, a control unit 12, and a heater 13, and in one embodiment, it may also include an evaporator 14. Furthermore, a tobacco stick 2 (e.g., a cigarette, an aerosol generating article, or a tobacco cartridge) may be inserted into the internal space of the aerosol generating apparatus 1.

[0037] In the following text, although the object inserted into the aerosol generating device 1 according to various embodiments of the present invention is described as "cigarette stick 2", the object inserted into the aerosol generating device 1 is not limited to cigarette stick 2. For example, various objects such as cigarettes, cigarette cartridges or other electronic devices can be inserted into the aerosol generating device 1.

[0038] Figure 1 and Figure 2 The aerosol generating apparatus 1 shown illustrates components relevant to this embodiment. Therefore, those skilled in the art should understand that, in addition to… Figure 1 and Figure 2 In addition to the components shown, the aerosol generating apparatus 1 may also include other general-purpose components.

[0039] exist Figure 1 In the diagram, battery 11, control unit 12, evaporator 14, and heater 13 are shown arranged in series; Figure 2 In the diagram, the evaporator 14 and the heater 13 are shown arranged in parallel. However, the internal structure of the aerosol generating device 1 is not limited to... Figure 1 and Figure 2 The structure shown is as follows. Depending on the design of the aerosol generating device 1, the arrangement of the battery 11, control unit 12, heater 13, and evaporator 14 may be changed.

[0040] In one embodiment, when the cigarette stick 2 is inserted into the aerosol generating device 1, the aerosol generating device 1 can operate the heater 13 and / or the evaporator 14 to generate an aerosol. The aerosol generated by the heater 13 and / or the evaporator 14 can pass through the cigarette stick 2 and be delivered to the user. If necessary, the aerosol generating device 1 can heat the heater 13 even if the cigarette stick 2 is not inserted into the aerosol generating device 1.

[0041] In one embodiment, the battery 11 can provide the power required for the operation of the aerosol generating device 1. For example, the battery 11 can supply power to the evaporator 14 so that the heater 13 or the evaporator 14 can be heated, and can also supply power to operate the control unit 12. In addition, the battery 11 can provide the power required for the operation of displays, sensors, motors, etc. installed in the aerosol generating device 1.

[0042] In one embodiment, the control unit 12 can control the operation of the aerosol generating device 1 as a whole. Specifically, in addition to the battery 11, heater 13, and evaporator 14, the control unit 12 can also control the operation of other components included in the aerosol generating device 1. Furthermore, the control unit 12 can verify the status of each component of the aerosol generating device 1 to determine whether the aerosol generating device 1 is in an operational state.

[0043] In one embodiment, the control unit 12 may include at least one processor. The processor may be implemented as a plurality of gate arrays, or as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. It will be readily understood by those skilled in the art that the at least one processor may be other forms of hardware.

[0044] In one embodiment, the heater 13 can be heated by power supplied by the battery 11. For example, when the cigarette is inserted into the aerosol generating device 1, the heater 13 can be located outside the cigarette. The heated heater 13 can increase the temperature of the aerosol generating material inside the cigarette.

[0045] For example, heater 13 can be a resistance heater. For example, heater 13 can include an electrical conduction track, and heater 13 can be heated when current flows through the electrical conduction track. However, heater 13 is not limited to the above examples; any example of heating heater 13 to a desired temperature is applicable and not limited. The desired temperature can be preset in the aerosol generating apparatus 1 or set by the user.

[0046] In one embodiment, heater 13 may be an induction heater. Specifically, heater 13 may include a conductive coil for heating the cigarette in an induction heating manner, and the cigarette may include a sensor to be heated by the induction heater.

[0047] For example, heater 13 may include tubular heating elements, plate heating elements, needle heating elements or rod heating elements, which can heat the inside or outside of the smoke rod 2 according to the shape of the heating elements.

[0048] In one embodiment, multiple heaters 13 may be provided in the aerosol generating apparatus 1. In this case, the multiple heaters 13 may be configured to be inserted into the interior of the tobacco stick 2 or disposed on the exterior of the tobacco stick 2. Furthermore, some of the multiple heaters 13 may be configured to be inserted into the interior of the tobacco stick 2, while the rest may be disposed on the exterior of the tobacco stick 2. In addition, the shape of the heaters 13 is not limited to... Figure 1 and Figure 2 The shape shown can be set to various shapes.

[0049] In one embodiment, the evaporator 14 can heat the liquid composition to generate an aerosol, and the generated aerosol can be delivered to the user via the cigarette stick 2. The aerosol generated by the evaporator 14 can travel along the airflow path of the aerosol generating device 1, which is configured such that the aerosol generated by the evaporator 14 can be delivered to the user via a cigarette.

[0050] For example, the evaporator 14 may include, but is not limited to, a liquid storage unit, a liquid transfer means, and a heating element. For example, the liquid storage unit, the liquid transfer means, and the heating element may be incorporated as independent modules into the aerosol generating apparatus 1.

[0051] In one embodiment, the liquid reservoir can store a liquid composition. For example, the liquid composition can be a liquid containing tobacco-containing substances including volatile tobacco aroma components, or it can be a liquid containing non-tobacco-containing substances. The liquid reservoir can be integrally formed with the evaporator 14 or detachably connected to the evaporator 14.

[0052] For example, the liquid composition may include water, solvent, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Fragrances may include, for example, menthol, peppermint, spearmint oil, various fruit flavoring ingredients, etc., but the embodiments are not limited thereto. Flavorings may include ingredients that provide the user with various flavors or aromas. Vitamin mixtures may be mixtures of at least one of vitamin A, vitamin B, vitamin C, or vitamin E; however, the embodiments are not limited thereto. Additionally, the liquid composition may also include aerosol forming agents, such as glycerin and propylene glycol.

Furthermore, the heating element may include conductive wires (e.g., nichrome wire) and may be arranged in a structure surrounding the liquid transfer means. Powering the heating element causes it to begin heating, thereby transferring heat to the liquid composition in contact with the heating element to heat the liquid composition. Ultimately, an aerosol can be generated.

[0055] In one embodiment, the vaporizer 14 may also be referred to as a cartomizer or atomizer, but is not limited thereto.

Furthermore, the aerosol generating device 1 may also include at least one sensor (e.g., a puff detection sensor, a temperature detection sensor, a cigarette insertion detection sensor, etc.). Moreover, the aerosol generating device 1 may be manufactured to allow external air to enter or internal gas to exit even when a cigarette stick 2 is inserted.

[0057] Although Figure 1 and Figure 2 Although not shown, the aerosol generating device 1 can form a system with a separate support. For example, the support can be used to charge the battery 11 of the aerosol generating device 1. Alternatively, the heater 13 can be used to heat the aerosol generating device 1 while the support is combined with the aerosol generating device 1.

[0058] In one embodiment, the cigarette stick 2 can resemble a typical combustible cigarette. For example, the cigarette stick 2 can be divided into a first part including aerosol-generating material and a second part including a filter tip, etc. Alternatively, the second part of the cigarette stick 2 can also include aerosol-generating material. For example, aerosol-generating material provided in granular or capsule form can be inserted into the second part.

[0059] In one embodiment, the first portion may be fully inserted into the aerosol generating device 1, while the second portion may be exposed to the outside. Alternatively, only a portion of the first portion may be inserted into the aerosol generating device 1, or the first portion may be fully inserted into the aerosol generating device 1, while a portion of the second portion may be inserted into the aerosol generating device 1. The user can then inhale the aerosol by holding the second portion in their mouth. When external air passes through the first portion, an aerosol can be generated, and the generated aerosol can enter the user's mouth through the second portion.

[0060] In one embodiment, external air can be introduced through at least one airway formed in the aerosol generating device 1. For example, the user can adjust the opening or closing and / or size of the airway formed in the aerosol generating device 1. Thus, the user can adjust the amount of vaporization, the smoking sensation, etc. In another embodiment, external air can be introduced into the interior of the cigarette stick 2 through at least one hole formed on the surface of the cigarette stick 2.

[0174] In one embodiment of this disclosure, blocking light of the first wavelength transmitted to the light receiving unit 455 by the filter 480 can improve the recognition accuracy of the sensor module 450. Furthermore, in one embodiment of this disclosure, the sensor module 450 including the filter 480 can simplify the design of at least one processor and / or memory.

[0175] For example, when the light receiving unit 455 receives light including a first wavelength, at least one processor and / or memory may need to select a second wavelength of light from the light received by the light receiving unit 455, or may need to ignore or block the first wavelength of light. At least one processor and / or memory may require additional components or circuitry (or operationally, via program or other means), which may increase design complexity.

[0176] An aerosol generating apparatus according to an embodiment of the present disclosure can provide advantages in terms of identification accuracy and design complexity of at least one processor and / or memory by using a filter 480 to block light of a first wavelength in the sensor module 450 stage.

[0177] In one embodiment, filter 480 may include at least a portion of optical filter 481, filter element 482, and switching element 483. Reference will be made below. Figure 6cThe filtering method and components of filter 480 are described exemplarily. However, the method and components of filter 480 described below are merely examples, and filter 480 can filter the light received by light receiving unit 455 in various ways using various components.

[0178] In one embodiment, the optical filter 481 can reflect (or absorb) light of a first wavelength. The optical filter 481 may be configured to physically surround at least a portion of the light receiving unit 455. The optical filter 481 may be disposed on the outer peripheral surface of the light receiving unit 455. Alternatively, the optical filter 481 may be disposed within the molded member 460. The optical filter 481 can reduce the design complexity of the filter 480 by physically or structurally blocking light of the first wavelength.

[0179] In one embodiment, the filter element 482 can controllably filter the detection results of the sensor module 450. The filter element 482 can be controllably connected to the light receiving unit 455. For example, the filter element 482 can be implemented as a wafer filter.

[0180] In one embodiment, the filter element 482 can perform noise reduction on the first wavelength of light received by the light receiving unit 455. The filter element 482 can be disposed on the light receiving unit 455 or the substrate 458. For example, the filter element 482 can be a second element 456 or part of the substrate 458.

[0181] In one embodiment, the switching element 483 can controllably filter the detection results of the sensor module 450. The switching element 483 can be controllably connected to the light-emitting unit 451 and / or the light-receiving unit 455. For example, the switching element 483 can be implemented as a wafer filter.

[0182] In one embodiment, the switching element 483 can block light emission from the light-emitting unit 451 while the light-receiving unit 455 receives light. The switching element 483 may be disposed on the light-emitting unit 451 or the substrate 458. For example, the filter element 482 may be part of the first element 452 or the substrate 458.

[0183] Figure 7a and Figure 7b This is a graph showing the detection results of a sensor module according to one embodiment.

[0184] Specifically, Figure 7a and Figure 7b The following graph is shown: when the sensor module (e.g., Figure 3 Sensing unit 120, Figure 4a and Figure 4b Sensor module 250, Figure 5 Sensor module 350 or Figure 6a ,Figure 6b and Figure 6c The light-emitting unit of the sensor module 450 (e.g., Figure 4b Light-emitting unit 251 Figure 5 The light-emitting unit 351 or Figure 6a , Figure 6b and Figure 6c When the light-emitting unit 451 emits the first wavelength W1, the light-receiving unit (e.g., Figure 4b Optical receiving unit 255 Figure 5 Optical receiving unit 355 or Figure 6a , Figure 6b and Figure 6c The wavelength responsivity of the light received by the light receiving unit 455.

[0185] For example, Figure 7a This can be shown in a filtered light (e.g., Figure 6c The responsivity, which varies according to the wavelength of light received by the sensor module before being filtered by a filter. Or, Figure 7a This can be a measure of the responsivity, showing how it varies with the wavelength of light received by the sensor module when the sensor module does not include a filter. The responsivity can be a parameter that displays the wavelength with the highest light intensity (1.0) received by the light receiving unit relative to adjacent wavelengths.

[0186] For example, Figure 7b This could be the responsivity, showing how the light changes according to the wavelength of the light received by the sensor module after being filtered by a filter. Alternatively, Figure 7b This can be an indication of the responsivity as it varies depending on the wavelength of the light received by the sensor module when the sensor module includes a filter.

[0187] In one embodiment, the light emitted by the light-emitting unit at a first wavelength W1 can be light with a wavelength that substantially comprises the first wavelength W1. For example, the first wavelength W1 can be a wavelength between 960 nm and 990 nm.

[0188] refer to Figure 7a When the light-emitting unit emits light of the first wavelength W1, the amount of light of the first wavelength W1 can be at its maximum, and the amount of light of the actual (or approximately) wavelength may tend to decrease as the distance from the first wavelength W1 increases.

[0189] However, the terms “substantially,” “approximately,” or “about” used herein may refer to the same level to reflect tolerances or errors in general manufacturing processes. Alternatively, the terms “substantially,” “approximately,” or “about” may be a range based on the literal 0%, including any of the ranges of + / -0.1%, + / -0.5%, + / -1%, + / -3%, + / -5%, + / -7%, + / -10%, + / -15%, and + / -20%.

[0190] In one embodiment, light of the first wavelength W1 can be used in aerosol-generated articles (e.g., Figure 1 and Figure 2 Cigarette stick 2 Figure 4a and Figure 4b Aerosol generating products 201 or Figure 5 The identification area of ​​the aerosol-generating article 301 (e.g., Figure 4a and Figure 4b The identification area 203 or Figure 5 The light is excited in the recognition region 303, and the recognition region can emit light of a second wavelength W2 that is different from the first wavelength W1.

[0191] In one embodiment, the light emitted from the identification unit at a second wavelength W2 can be light whose wavelength substantially comprises the second wavelength W2. For example, the second wavelength W2 can be a wavelength between 1000 nm and 1020 nm.

[0192] Reference Figure 7a and Figure 7b When the light-emitting unit emits light of the second wavelength W2, the amount of light of the second wavelength W2 can be at its maximum, and the amount of light of the actual (or approximately) wavelength may tend to decrease as the distance from the second wavelength W2 increases.

[0193] In one embodiment, the filter can filter wavelengths within a first filtering range Fw. The first filtering range Fw can be a range including the first wavelength W1, which is between a first wavelength W1 and a second wavelength W2. For example, the first filtering range Fw can be wavelengths less than 1000 nm.

[0194] In one embodiment, at least one processor (e.g., Figure 1 and Figure 2 Control Unit 12 Figure 3 Control Unit 110 Figure 4b At least one processor 260 or Figure 5 At least one processor 360 can execute data stored in memory (e.g., Figure 3 Memory 170, Figure 4b memory 265 or Figure 5The instructions in the memory 365) identify identification information about aerosol-generating articles based on the amount of light at a second wavelength W2 outside the first filtering range Fw.

[0195] In embodiments of this disclosure, when the difference between the first wavelength W1 and the second wavelength W2 is small—for example, when both the light of the first wavelength W1 and the light of the second wavelength W2 are infrared light—at least one processor may have difficulty identifying the identification information based on the amount of light of the second wavelength W2, and the identification result may contain errors or have reduced accuracy. A sensor module according to an embodiment of this disclosure can physically block or controllably noise-process a first filtering range Fw including the light of the first wavelength W1 using a filter, thereby reducing or eliminating errors in the identification result and improving identification accuracy.

[0252] In the following description, any content that overlaps with the foregoing will be omitted, and it should be understood that, to the extent readily understood by those skilled in the art with reference to the following figures and description, some components and structures of the sensor module 650-1 may be replaced, added, or omitted. Furthermore, unless technically clearly impractical, at least one component or feature in the above embodiments may be combined with an electronic device.

[0253] In one embodiment, the sensor module 650-1 may include a light-emitting unit 651-1 and a light-receiving unit 655-1 (e.g., Figure 4b Optical receiving unit 255 Figure 5 Optical receiving unit 355 Figure 6a and Figure 6b Optical receiving unit 455 Figure 9 Optical receiver unit 555 or Figure 13 The light receiving unit 655 and the substrate 658-1 (e.g., Figure 6a and Figure 6b substrate 458, Figure 9 substrate 558 or Figure 13 Substrate 658).

[0254] Although not shown in the figure, sensor module 650-1 may also include, as referenced above. Figures 6a to 13 At least a portion of a component (e.g., a molded member, partition, etc.) of a sensor module of at least one embodiment described herein.

As the amount of light of the first wavelength emitted by the sensor module 650-1 increases, the amount of light whose optical properties change (e.g., light of the second wavelength) transmitted to the light-receiving unit 655-1 also increases, thereby improving the sensing accuracy of the sensor module 650-1.
