Aerosol generating device including a sensor module
[0001] Various embodiments disclosed in this document relate to an aerosol generating device including a sensor module.
[0002] Recently, there has been a growing demand for alternative products that overcome the shortcomings of traditional cigarettes. For example, demand is growing for devices that generate aerosol by electrically heating a cigarette stick (e.g., heat-not-burn electronic cigarettes). Accordingly, research is actively underway on cigarette sticks (or aerosol-generating devices) and electrically heated aerosol-generating devices into which the cigarette stick is inserted.
[0003] The background technology described above is technology that the inventor possessed or acquired in the process of deriving the disclosure of the present application, and cannot necessarily be said to be publicly known technology disclosed to the general public prior to the present application.
[0004] Aerosol-generating devices can be used with various types of aerosol-generating articles inserted into them. Aerosol-generating articles include aerosol-generating substances, and may be, for example, cigarettes, sticks, capsules, liquid substances, or cartridges.
[0005] The aerosol-generating device can identify information about the aerosol-generating item and generate aerosol based on this information. For example, the aerosol-generating device can control the operation of the heater based on information about the inserted stick, thereby providing a temperature profile appropriate for each stick.
[0006] If the aerosol-generating device cannot recognize the aerosol-generating item itself, the user must manually enter the type of aerosol-generating item being inserted, which is cumbersome. Furthermore, creating markers for identifying each aerosol-generating item presents various challenges, and depending on the recognition method, the aerosol-generating device's recognition accuracy can sometimes be reduced.
[0007] In one embodiment, an aerosol-generating device may include a housing including a cavity into which an aerosol-generating article can be inserted; a sensor module disposed in the cavity; at least one processor receiving a detection result 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 toward the cavity, a light-receiving unit receiving light emitted from the aerosol-generating article, and a filter filtering light of the first wavelength among light received by the light-receiving unit. In one embodiment, the at least one processor may recognize identification information for the aerosol-generating article based on an amount of light filtered by the filter by executing the instructions stored in the memory.
[0008] Alternatively, an aerosol-generating device according to one embodiment may include a housing including a cavity into which an aerosol-generating article can be inserted; a sensor module disposed in the cavity; at least one processor receiving a detection result 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 toward the cavity, a light-receiving unit receiving light emitted from the aerosol-generating article, and a filter for filtering light of the first wavelength among light received by the light-receiving unit. In one embodiment, the at least one processor may recognize identification information for the aerosol-generating article based on an amount of light filtered by the filter by executing the instructions stored in the memory.
[0009] An aerosol generating device including a sensor module of one embodiment can identify information about an inserted aerosol generating article (e.g., a cigarette, a stick, a capsule, or a cartridge) based on the amount of light of a specific wavelength transmitted to the light receiving unit.
[0010] Additionally, an aerosol generating device including a sensor module according to one embodiment may have design advantages in the control unit and may improve the accuracy of optical recognition. Furthermore, the manufacturing difficulty of the aerosol generating device according to one embodiment and the identification marker of the aerosol-generating article inserted therein may be improved.

[0033] Below, with reference to the attached drawings, embodiments of the present invention are described in detail so that those skilled in the art can easily implement the invention. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein.
[0034] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0035] Figures 1 and 2 are drawings showing examples of cigarettes inserted into an aerosol generating device.
[0036] Referring to FIGS. 1 and 2, an aerosol generating device (1) according to one embodiment may include a battery (11), a control unit (12), and a heater (13), and in one embodiment, may further include a vaporizer (14). In addition, a stick (2) (e.g., a cigarette, an aerosol generating article, or a cartridge) may be inserted into the internal space of the aerosol generating device (1).
[0037] Hereinafter, an object inserted into an aerosol generating device (1) according to various embodiments of the present document is described as a 'stick (2)', but the object inserted into the aerosol generating device (1) is not limited to a stick (2), and various objects such as, for example, a cigarette, a cartridge, or other electronic devices may be inserted into the aerosol generating device (1).
[0038] The aerosol generating device (1) illustrated in FIGS. 1 and 2 illustrates components related to the present embodiment. Accordingly, a person skilled in the art related to the present embodiment will understand that, in addition to the components illustrated in FIGS. 1 and 2, the aerosol generating device (1) may further include other general-purpose components.
[0039] In Fig. 1, the battery (11), the control unit (12), the vaporizer (14), and the heater (13) are illustrated as being arranged in a row, and in Fig. 2, the vaporizer (14) and the heater (13) are illustrated as being arranged in parallel. However, the internal structure of the aerosol generating device (1) is not limited to that illustrated in Figs. 1 and 2. Depending on the design of the aerosol generating device (1), the arrangement of the battery (11), the control unit (12), the heater (13), and the vaporizer (14) may be changed.
[0040] In one embodiment, when the stick (2) is inserted into the aerosol generating device (1), the aerosol generating device (1) can operate the heater (13) and / or the vaporizer (14) to generate an aerosol. The aerosol generated by the heater (13) and / or the vaporizer (14) passes through the stick (2) and is delivered to the user. If necessary, the aerosol generating device (1) can heat the heater (13) even when the stick (2) is not inserted into the aerosol generating device (1).
[0041] In one embodiment, the battery (11) supplies power used to operate the aerosol generating device (1). For example, the battery (11) may supply power to heat the heater (13) or the vaporizer (14), and may supply power required for the control unit (12) to operate. In addition, the battery (11) may supply power required for the operation of the display, sensors, motors, etc. installed in the aerosol generating device (1).
[0042] In one embodiment, the control unit (12) controls the overall operation of the aerosol generating device (1). Specifically, the control unit (12) controls the operation of the battery (11), the heater (13), and the vaporizer (14), as well as other components included in the aerosol generating device (1). In addition, the control unit (12) can also check the status of each component of the aerosol generating device (1) to determine whether the aerosol generating device (1) is in an operable state.
[0043] In one embodiment, the control unit (12) may include at least one processor. The at least one processor may be implemented as an array of multiple logic gates. Alternatively, the at least one processor may be implemented as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Furthermore, those skilled in the art will appreciate that the present embodiment may be implemented as other types of hardware.
[0044] In one embodiment, the heater (13) may be heated by power supplied from the battery (11). For example, when a cigarette is inserted into the aerosol generating device (1), the heater (13) may be located on the outside of the cigarette. The heated heater (13) may increase the temperature of the aerosol generating material within the cigarette.
[0045] In one embodiment, the heater (13) may be an electrically resistive heater. For example, the heater (13) may include an electrically conductive track, and the heater (13) may be heated as current flows through the electrically conductive track. However, the heater (13) is not limited to the above-described example, and may be any heater that can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generating device (1), or may be set to a desired temperature by the user.
[0046] In one embodiment, the heater (13) may be an induction heater. Specifically, the heater (13) may include an electrically conductive coil for inductively heating a cigarette, and the cigarette may include a susceptor that can be heated by the induction heater.
[0047] For example, the heater (13) may include a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and may heat the inside or outside of the stick (2) depending on the shape of the heating element.
[0048] In one embodiment, a plurality of heaters (13) may be arranged in the aerosol generating device (1). At this time, the plurality of heaters (13) may be arranged to be inserted into the interior of the stick (2) or may be arranged on the exterior of the stick (2). In addition, some of the plurality of heaters (13) may be arranged to be inserted into the interior of the stick (2), and the remainder may be arranged on the exterior of the stick (2). In addition, the shape of the heater (13) is not limited to the shape illustrated in FIGS. 1 and 2, and may be manufactured in various shapes.
[0049] In one embodiment, the vaporizer (14) can heat the liquid composition to generate an aerosol, and the generated aerosol can be delivered to the user through the stick (2). The aerosol generated by the vaporizer (14) can travel along the airflow path of the aerosol generating device (1), and the airflow path can be configured such that the aerosol generated by the vaporizer (14) can pass through the cigarette and be delivered to the user.
[0050] For example, the vaporizer (14) may include, but is not limited to, a liquid storage unit, a liquid delivery means, and a heating element. For example, the liquid storage unit, the liquid delivery means, and the heating element may be included in the aerosol generating device (1) as independent modules.
[0051] In one embodiment, the liquid reservoir can store a liquid composition. For example, the liquid composition can be a liquid containing a tobacco-containing material including volatile tobacco flavoring components, or a liquid containing a non-tobacco material. The liquid reservoir can be constructed to be detachable from / attached to the vaporizer (14), or can be constructed integrally with the vaporizer (14).
[0052] For example, the liquid composition may include water, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture. The flavoring agent may include, but is not limited to, menthol, peppermint oil, spearmint oil, and various fruit-flavored ingredients. The flavoring agent may include ingredients that can provide a variety of flavors or tastes to the user. The vitamin mixture may include, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. Additionally, the liquid composition may include an aerosol-forming agent such as glycerin and propylene glycol.
[0053] In one embodiment, the liquid delivery means can deliver the liquid composition from the liquid storage to the heating element. For example, the liquid delivery means can be a wick such as, but not limited to, cotton fibers, ceramic fibers, glass fibers, or porous ceramics.
[0054] In one embodiment, the heating element is an element for heating a liquid composition delivered by a liquid delivery means. For example, the heating element may be, but is not limited to, a metal heating wire, a metal heating plate, a ceramic heater, etc. In addition, the heating element may be composed of a conductive filament, such as a nichrome wire, and may be arranged in a structure that is wound around the liquid delivery means. The heating element may be heated by a current supply and may transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol may be generated.
[0055] For example, the vaporizer (14) may be referred to as a cartomizer or an atomizer, but is not limited thereto.
[0056] In one embodiment, the aerosol generating device (1) may further include general-purpose components in addition to the battery (11), the control unit (12), the heater (13), and the vaporizer (14). For example, the aerosol generating device (1) may include a display capable of outputting visual information and / or a motor for outputting tactile information. In addition, the aerosol generating device (1) may include at least one sensor (a puff detection sensor, a temperature detection sensor, a cigarette insertion detection sensor, etc.). In addition, the aerosol generating device (1) may be manufactured in a structure in which external air can be introduced or internal gas can be discharged even when the stick (2) is inserted.
[0057] Although not illustrated in FIGS. 1 and 2, the aerosol generating device (1) may be configured as a system with a separate cradle. For example, the cradle may be used to charge the battery (11) of the aerosol generating device (1). Alternatively, the heater (13) may be heated while the cradle and the aerosol generating device (1) are combined.
[0058] In one embodiment, the stick (2) may resemble a typical combustible cigarette. For example, the stick (2) may be divided into a first portion containing an aerosol-generating substance and a second portion containing a filter or the like. Alternatively, the second portion of the stick (2) may also contain an aerosol-generating substance. For example, an aerosol-generating substance in the form of granules or capsules may be inserted into the second portion.
[0059] In one embodiment, the entire first part may be inserted into the interior of the aerosol generating device (1), and the second part may be exposed to the outside. Alternatively, only a portion of the first part may be inserted into the interior of the aerosol generating device (1), or the entire first part and a portion of the second part may be inserted. The user may inhale the aerosol while holding the second part in their mouth. The aerosol is generated by external air passing through the first part, and the generated aerosol passes through the second part and is delivered to the user's mouth.
[0060] In one embodiment, outside air may be introduced through at least one air passage formed in the aerosol generating device (1). For example, the opening and / or the size of the air passage formed in the aerosol generating device (1) may be controlled by the user. Accordingly, the amount of vapor, the smoking sensation, etc. may be controlled by the user. As another example, outside air may be introduced into the interior of the stick (2) through at least one hole formed on the surface of the stick (2).

Furthermore, computer-readable media may include both computer storage media and communication media. Computer storage media may include both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information, such as computer-readable instructions, data structures, program modules, or other data.

The cover (217) may be movably (e.g., slidably) coupled to one side of the housing (210). The cover (217) may open and close the inlet (211).
[0099] Hereinafter, an object inserted or removed from an aerosol generating device (200) according to various embodiments of this document is referred to as an 'aerosol generating article (201)', but is not limited to this when actually implementing the aerosol generating device (200).

[0171] However, "substantially" in this document may mean the same level, reflecting tolerances or errors in typical manufacturing processes. Alternatively, "substantially" may refer to a range that includes any of + / -0.1%, + / -0.5%, + / -1%, + / -3%, + / -5%, + / -7%, + / -10%, + / -15%, and + / -20%, based on the literal equivalent 0%.
[0172] In one embodiment, the filter (480) can filter at least a portion of the light received by the light receiving unit (455). For example, the filter (480) can filter light of a first wavelength among the light received by the light receiving unit (455). Alternatively, for example, the filter (480) can filter light of a portion of the light received by the light receiving unit (455) that includes light of the first wavelength.
[0173] In one embodiment, at least one processor (e.g., the control unit (12) of FIGS. 1 and 2, the control unit (110) of FIG. 3, at least one processor (260) of FIG. 4B, or at least one processor (360) of FIG. 5) can recognize identification information for an aerosol-generating article (e.g., the stick (2) of FIGS. 1 and 2, the aerosol-generating article (201) of FIGS. 4A and 4B, or the aerosol-generating article (301) of FIG. 5) based on the amount of light filtered by the filter (480) by executing instructions stored in a memory (e.g., the memory (170) of FIG. 3, the memory (265) of FIG. 4B, or the memory (365) of FIG. 5).
[0174] In one embodiment of the present document, the filter (480) can improve the identification accuracy of the sensor module (450) by blocking the light of the first wavelength transmitted to the light receiving unit (455). In addition, in one embodiment of the present document, the sensor module (450) including the filter (480) can provide ease in the design of at least one processor and / or memory.
[0175] For example, when the light receiving unit (455) receives light including light of the first wavelength, at least one processor and / or memory needs to select light of the second wavelength among the light received by the light receiving unit (455), or ignore or block light of the first wavelength. At least one processor and / or memory may require additional configuration or operation circuit-wise (or operationally, programmatically, or in a different manner), and design difficulty may increase.
[0176] An aerosol generating device according to one embodiment of the present invention may have an advantage in design difficulty of at least one processor and / or memory as well as in providing identification accuracy by having a filter (480) block light of a first wavelength at the sensor module (450) stage.
[0177] In one embodiment, the filter (480) may include at least some of an optical filter (481), a filter element (482), and a switching element (483). Hereinafter, a filtering method and configuration of the filter (480) will be exemplarily described with reference to FIG. 6C. However, the method and configuration of the filter (480) described below are merely examples, and the filter (480) may filter light received by the light receiving unit (455) in various methods and configurations.
[0178] In one embodiment, the optical filter (481) can reflect (or absorb) light of the first wavelength. The optical filter (481) can be physically arranged to surround at least a portion of the light receiving unit (455). The optical filter (481) can be arranged on an outer surface of the light receiving unit (455). Alternatively, the optical filter (481) can be arranged on the molding member (460). The optical filter (481) can provide an advantage in design difficulty 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 noise-process light of a first wavelength among the 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 part of the second element (456) or 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 the light emission of the light emitting unit (451) while the light receiving unit (455) receives light. The switching element (483) can be disposed in the light emitting unit (451) or the substrate (458). For example, the filter element (482) can be a part of the first element (452) or the substrate (458).
[0183] FIG. 7a and FIG. 7b are graphs illustrating detection results of a sensor module according to one embodiment.
[0184] Specifically, FIGS. 7A and 7B are graphs showing the response according to the wavelength of light received by a light-receiving unit (e.g., the light-receiving unit (255) of FIG. 4B, the light-receiving unit (355) of FIG. 5, or the light-receiving unit (455) of FIGS. 6A, 6B, and 6C) when a light-emitting unit (e.g., the light-emitting unit (251) of FIG. 4B, the light-receiving unit (351) of FIG. 5, or the light-receiving unit (451) of FIGS. 6A, 6B, and 6C) of a sensor module (e.g., the sensing unit (120) of FIG. 3, the sensor module (250) of FIGS. 4A and 4B, the sensor module (350) of FIG. 5, or the sensor module (450) of FIGS. 6A, 6B, and 6C) emits a first wavelength (W1).
[0185] For example, Fig. 7a may be a response graph according to the wavelength of light received by the sensor module before being filtered by a filter (e.g., the filter of Fig. 6c). Alternatively, Fig. 7a may be a response graph according to the wavelength of light received by the sensor module when the sensor module does not include a filter. The response graph may be a parameter that relatively indicates light of adjacent wavelengths based on the wavelength with the largest amount of light received by the light receiving unit (1.0).
[0186] For example, Fig. 7b may be a response diagram according to the wavelength of light received by the sensor module after being filtered by the filter. Alternatively, Fig. 7b may be a response diagram according to the wavelength of light received by the sensor module when the sensor module includes a filter.
[0187] In one embodiment, light of the first wavelength (W1) emitted from the light emitting unit may mean light of a wavelength that substantially primarily includes light of the first wavelength (W1). For example, the first wavelength (W1) may be a wavelength between 960 nm and 990 nm.
[0188] Referring to Fig. 7a, when the light emitting unit emits light of the first wavelength (W1), it can be seen that the amount of light of the first wavelength (W1) is the largest, and the amount of light of the wavelength substantially (or approximately) decreases as distance from the first wavelength (W1) increases.
[0189] However, "substantially," "approximately," or "about" in this document may mean the same level, reflecting tolerances or errors in general manufacturing processes. Alternatively, "substantially," "approximately," or "about" may refer to a range including any one of + / -0.1%, + / -0.5%, + / -1%, + / -3%, + / -5%, + / -7%, + / -10%, + / -15%, and + / -20%, based on the literal equivalent 0%.
[0190] In one embodiment, light of a first wavelength (W1) is excited at an identification region (e.g., identification region (203) of FIGS. 4A and 4B or identification region (303) of FIG. 5) of an aerosol-generating article (e.g., stick (2) of FIGS. 1 and 2, aerosol-generating article (201) of FIGS. 4A and 4B or aerosol-generating article (301) of FIG. 5), and the identification region can emit light of a second wavelength (W2) different from the first wavelength (W1).
[0191] In one embodiment, the light of the second wavelength (W2) emitted from the identification unit may mean light of a wavelength that substantially primarily includes light of the second wavelength (W2). For example, the second wavelength (W2) may be a wavelength between 1000 nm and 1020 nm.
[0192] Referring to FIGS. 7a and 7b, when the identification area emits light of the second wavelength (W2), it can be seen that the amount of light of the second wavelength (W2) is the largest, and the amount of light of the wavelength substantially (or approximately) decreases as it moves away from the second wavelength (W2).
[0193] In one embodiment, the filter can filter wavelengths in a first filtering range (Fw). The first filtering range (Fw) can be a range from a reference wavelength between the first wavelength (W1) and the second wavelength (W2) to include the first wavelength (W1). For example, the first filtering range (Fw) can be a wavelength less than 1000 nm.
[0194] In one embodiment, at least one processor (e.g., the control unit (12) of FIGS. 1 and 2, the control unit (110) of FIG. 3, at least one processor (260) of FIG. 4b, or at least one processor (360) of FIG. 5) can recognize identification information for an aerosol-generating article based on the amount of light of a second wavelength (W2) outside the first filtering range (Fw) by executing instructions stored in a memory (e.g., the memory (170) of FIG. 3, the memory (265) of FIG. 4b, or the memory (365) of FIG. 5).
[0195] In one embodiment of the present document, when the difference between the first wavelength (W1) and the second wavelength (W2) is not large, for example, when both the light of the first wavelength (W1) and the light of the second wavelength (W2) are infrared rays, at least one processor may have difficulty recognizing identification information based on the amount of light of the second wavelength (W2), and there is a possibility that an error may occur in the identification result or the accuracy may be reduced. The sensor module according to one embodiment of the present document can reduce or eliminate an error in the identification result and improve the identification accuracy by physically blocking or controllably noise-processing a first filtering range (Fw) including the light of the first wavelength (W1) through a filter.
[0196] FIG. 8 is a side view of a sensor module (450-1) according to one embodiment.
[0197] Referring to FIG. 8, a molding member (460-1) (e.g., the molding member (460) of FIGS. 6a, 6b, and 6c) of a sensor module (450-1) (e.g., the sensing unit (120) of FIG. 3, the sensor module (250) of FIGS. 4a and 4b, the sensor module (350) of FIG. 5, or the sensor module (450) of FIGS. 6a, 6b, and 6c) according to one embodiment may further include a first dome-shaped molding region (463-1).
[0198] In the following, any content that overlaps with the above will be omitted for explanation, and it should be understood that some components and structures of the sensor module (450-1) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the above-described embodiments may be combined with an electronic device, unless it is technically clearly impossible.
[0199] In one embodiment, the sensor module (450-1) may include a light-emitting unit (451-1) (e.g., light-emitting unit (251) of FIG. 4B, light-emitting unit (351) of FIG. 5, or light-emitting unit (451) of FIGS. 6A, 6B, and 6C), a light-receiving unit (455-1) (e.g., light-receiving unit (255) of FIG. 4B, light-receiving unit (355) of FIG. 5, or light-receiving unit (455) of FIGS. 6A, 6B, and 6C), a substrate (458-1) (e.g., substrate (458) of FIGS. 6A, 6B, and 6C), and a molding member (460-1).
[0200] In one embodiment, the first dome-shaped molding region (463-1) may be positioned at a position corresponding to the light emitting unit (451-1) on one side (e.g., a side in the +Z direction) of the base region (461-1) (e.g., the base region (461) of FIGS. 6A, 6B, and 6C) facing the cavity (e.g., the cavity (213) of FIGS. 4A and 4B or the cavity (313) of FIG. 5). The first dome-shaped molding region (463-1) may guide light emitted from the light emitting unit (451-1).
[0201] For example, the first dome-shaped molding region (463-1) can guide at least a portion of the light emitted from the light emitting unit (451-1) to be focused on an identification region (e.g., identification region (203) of FIGS. 4A and 4B or identification region (303) of FIG. 5) of a detection target (e.g., stick (2) of FIGS. 1 and 2, aerosol-generating article (201) of FIGS. 4A and 4B or aerosol-generating article (301) of FIG. 5) of the sensor module (450-1).
[0202] In one embodiment of the present document, the first dome-shaped molding area (463-1) can provide light transmission efficiency of the light emitting unit (451-1), and the sensor module (450-1) can improve sensing accuracy through the first dome-shaped molding area (463-1).
[0203] In one embodiment, the first dome-shaped molding region (463-1) may be formed as a single body that is continuous with the base region (461-1). Alternatively, the first dome-shaped molding region (463-1) may have a discontinuous structure with the base region (461-1) and may be formed by being combined with the base region (461-1).
[0204] FIG. 9 is a side view of a sensor module (450-2) according to one embodiment.
[0205] Referring to FIG. 9, a molding member (460-2) (e.g., the molding member (460) of FIGS. 6a, 6b, and 6c or the molding member (460-1) of FIG. 8) of a sensor module (450-2) according to one embodiment (e.g., the sensing unit (120) of FIG. 3, the sensor module (250) of FIGS. 4a and 4b, the sensor module (350) of FIG. 5, the sensor module (450) of FIGS. 6a, 6b, and 6c or the sensor module (450-1) of FIG. 8) may further include a second dome-shaped molding region (465-2).
[0206] In the following, any content that overlaps with the above will be omitted for explanation, and it should be understood that some components and structures of the sensor module (450-2) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below.

[0207] In one embodiment, the sensor module (450-2) may include a light-emitting unit (451-2) (e.g., light-emitting unit (251) of FIG. 4B, light-emitting unit (351) of FIG. 5, light-emitting unit (451) of FIGS. 6A, 6B, and 6C, or light-emitting unit (451-1) of FIG. 8), a light-receiving unit (455-2) (e.g., light-receiving unit (255) of FIG. 4B, light-receiving unit (355) of FIG. 5, light-receiving unit (455) of FIGS. 6A, 6B, and 6C, or light-receiving unit (455-1) of FIG. 8), a substrate (458-2) (e.g., substrate (458) of FIGS. 6A, 6B, and 6C, or substrate (458-1) of FIG. 8), and a molding member (460-2).
[0208] In one embodiment, the molding member (460-2) may include at least one of a base region (461-2) (e.g., the base region (461) of FIGS. 6A, 6B, and 6C or the base region (461-1) of FIG. 8) and a first dome-shaped molding region (463-2) (e.g., the first dome-shaped molding region (463-1) of FIG. 8).
[0209] In one embodiment, the second dome-shaped molding region (465-2) may be positioned at a position corresponding to the light receiving unit (455-2) on one side (e.g., a side in the +Z direction) of the base region (461-2) facing the cavity (e.g., the cavity (213) of FIGS. 4A and 4B or the cavity (313) of FIG. 5). The second dome-shaped molding region (465-2) may guide light transmitted to the light receiving unit (455-2).
[0210] For example, the light receiving unit (455-2) can receive light emitted from an identification area (e.g., the identification area (203) of FIGS. 4A and 4B or the identification area (303) of FIG. 5) of a detection target (e.g., the stick (2) of FIGS. 1 and 2, the aerosol-generating article (201) of FIGS. 4A and 4B or the aerosol-generating article (301) of FIG. 5) of the sensor module (450-2).

In addition, at least one component or feature of the above-described embodiments may be combined with an electronic device, unless it is technically clearly impossible.
[0216] In one embodiment, the sensor module (550) may include a light-emitting unit (551) (e.g., light-emitting unit (251) of FIG. 4B, light-emitting unit (351) of FIG. 5, or light-emitting unit (451) of FIGS. 6A, 6B, and 6C), a light-receiving unit (555) (e.g., light-receiving unit (255) of FIG. 4B, light-receiving unit (355) of FIG. 5, or light-receiving unit (455) of FIGS. 6A, 6B, and 6C), a substrate (558) (e.g., substrate (458) of FIGS. 6A, 6B, and 6C), and a molding member (560) (e.g., molding member (460) of FIGS. 6A, 6B, and 6C).

[0223] In one embodiment, the partition wall (570) may be formed of an epoxy molding compound (EMC) material. The partition wall (570) may be formed of a material having relatively low light transmittance compared to the molding member (560). The partition wall (570) may prevent light emitted from the light emitting unit (551) from being transmitted to the light receiving unit (555).
