The terms used in the embodiments are selected from the most widely used general terms possible while considering the functions in the present invention, but this may vary depending on the intention of engineers working in the field, precedents, the emergence of new technologies, etc. In addition, in certain cases, there are terms arbitrarily selected by the applicant, and in this case, the meanings thereof will be described in detail in the description of the relevant invention. Therefore, the terms used in the present invention should be defined based on the meanings of the terms and the overall contents of the present invention, rather than simply the names of the terms.

When a part of the specification is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components, unless otherwise specifically stated. In addition, terms such as "... part", "... module", etc., described in the specification mean a unit that processes at least one function or operation, which may be implemented by hardware or software, or a combination of hardware and software.

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 present invention. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein.

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

Figures 1 and 2 are drawings illustrating examples of cigarettes inserted into an aerosol generating device.

Referring to FIG. 1, 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 cigarette (2) may be inserted into the internal space of the aerosol generating device (1).

The aerosol generating device (1) illustrated in FIGS. 1 and 2 illustrates components related to the present embodiment. Accordingly, a person having ordinary skill in the art related to the present embodiment will understand that, in addition to the components illustrated in FIGS. 1 and 2, other general-purpose components may be further included in the aerosol generating device (1).

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. In addition, 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. In other words, 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.

When a cigarette (2) is inserted into an aerosol generating device (1), the aerosol generating device (1) can generate an aerosol by operating a heater (13) and/or a vaporizer (14). The aerosol generated by the heater (13) and/or the vaporizer (14) passes through the cigarette (2) and is delivered to the user.

If necessary, the aerosol generating device (1) can heat the heater (13) even when the cigarette (2) is not inserted into the aerosol generating device (1).

The battery (11) supplies power used to operate the aerosol generating device (1). For example, the battery (11) can supply power so that the heater (13) or the vaporizer (14) can be heated, and can supply power required for the control unit (12) to operate. In addition, the battery (11) can supply power required for the display, sensor, motor, etc. installed in the aerosol generating device (1) to operate.

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 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.

The control unit (12) includes at least one processor. The processor may be implemented as an array of a plurality of logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing a program that can be executed by the microprocessor. In addition, it will be understood by those skilled in the art to which the present embodiment belongs that the processor may be implemented as other types of hardware.

The heater (13) can 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) can be located outside the cigarette. Accordingly, the heated heater (13) can increase the temperature of the aerosol generating material inside the cigarette.

The heater (13) may be an electrical resistance 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 applied without limitation as long as it 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.

Meanwhile, as another example, the heater (13) may be an induction heating heater. Specifically, the heater (13) may include an electrically conductive coil for heating the cigarette in an induction heating manner, and the cigarette may include a susceptor that can be heated by the induction heating heater.

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 the outside of the cigarette (2) depending on the shape of the heating element.

In addition, 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 inside of the cigarette (2) or may be arranged on the outside of the cigarette (2). In addition, some of the plurality of heaters (13) may be arranged to be inserted into the inside of the cigarette (2), and the rest may be arranged on the outside of the cigarette (2). In addition, the shape of the heater (13) is not limited to the shape illustrated in FIGS. 1 to 3, and may be manufactured in various shapes.

The vaporizer (14) can heat the liquid composition to generate an aerosol, and the generated aerosol can be delivered to the user through the cigarette (2). In other words, the aerosol generated by the vaporizer (14) can travel along the airflow passage of the aerosol generating device (1), and the airflow passage can be configured so that the aerosol generated by the vaporizer (14) can pass through the cigarette and be delivered to the user.

For example, the vaporizer (14) may include, but is not limited to, a liquid reservoir, a liquid delivery means, and a heating element. For example, the liquid reservoir, the liquid delivery means, and the heating element may be included in the aerosol generating device (1) as independent modules.

The liquid reservoir can store a liquid composition. For example, the liquid composition can be a liquid containing a tobacco-containing material including a volatile tobacco flavoring component, or can be a liquid containing a non-tobacco material. The liquid reservoir can be constructed to be detachable from/attachable to the vaporizer (14), or can be constructed integrally with the vaporizer (14).

For example, the liquid composition may include water, a solvent, ethanol, a plant extract, a flavor, a flavoring agent, or a vitamin mixture. The flavoring agent may include, but is not limited to, menthol, peppermint, spearmint oil, various fruit-flavored ingredients, and the like. 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. In addition, the liquid composition may include an aerosol forming agent, such as glycerin and propylene glycol.

The liquid transfer means can transfer the liquid composition from the liquid storage to the heating element. For example, the liquid transfer means can be a wick such as, but not limited to, cotton fibers, ceramic fibers, glass fibers, or porous ceramics.

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 supplying current, 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.

For example, the vaporizer (14) may be referred to as a cartomizer or an atomizer, but is not limited thereto.

Meanwhile, 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 with a structure in which external air may be introduced or internal gas may be discharged even when the cigarette (2) is inserted.

Although not shown in FIGS. 1 and 2, the aerosol generating device (1) may also 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.

The cigarette (2) may be similar to a typical combustible cigarette. For example, the cigarette (2) may be divided into a first part containing an aerosol generating substance and a second part containing a filter or the like. Alternatively, the second part of the cigarette (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 part.

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 part of the first part may be inserted into the interior of the aerosol generating device (1), or the entire first part and a part of the second part may be inserted. The user may inhale the aerosol while holding the second part in his mouth. At this time, the aerosol is generated by the outside air passing through the first part, and the generated aerosol passes through the second part and is delivered to the user's mouth.

As an example, outside air may be introduced through at least one air passage formed in the aerosol generating device (1). For example, the opening and closing of the air passage formed in the aerosol generating device (1) and/or the size of the air passage 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 cigarette (2) through at least one hole formed on the surface of the cigarette (2).

FIG. 4a is an exploded perspective view of an aerosol generating device (200) according to one embodiment, and FIG. 4b is a schematic diagram of an aerosol generating device according to one embodiment.

Referring to FIGS. 4a and 4b, an aerosol generating device (200) according to one embodiment (e.g., the aerosol generating device (1) of FIG. 1 or FIG. 2 or the aerosol generating device (100) of FIG. 3) may include a housing (205) and a cartridge (220).

A housing (205) according to one embodiment may be a housing assembly comprising a plurality of components, for example, including a body (210) and a cap (230), and the body (210) and the cap (230) may be detachably coupled to each other.

For example, the body (210) may be the main housing of the aerosol generating device (200) and may accommodate the entire body of the aerosol generating device (200) therein. The cap (230) may be a cover detachably coupled to the body (210).

In one embodiment, the body (210) can include an elongated cavity (212) that can accommodate a stick (e.g., a cigarette (2) of FIG. 1 or FIG. 2). The stick can be inserted longitudinally (e.g., in the Z-axis direction) into the elongated cavity (212).

In one embodiment, the body (210) can include at least a portion of an aerosol opening (214) and an aerosol path (216). The aerosol opening (214) can be in communication with the cartridge (220). The aerosol path (216) can be in communication with the aerosol opening (214) and the elongated cavity (212) and can receive aerosol from the cartridge (220) through the aerosol opening (214).

In one embodiment, the cap (230) can cover at least a portion of an outer surface of the body (210). The cap (230) can be removably coupled to the body (210), and a cartridge (220) can be accommodated between the cap (230) and the body (210).

In one embodiment, the cap (230) may include an intake port (232) provided at a position corresponding to the elongated cavity (212) of the body (210). The intake port (232) may be formed to be open on one side (e.g., the upper side or the side in the +Z direction) of the cap (230). When the cap (230) is coupled to the body (210), the intake port (232) and the elongated cavity (212) may be communicated.

In one embodiment, a cartridge (220) (e.g., a vaporizer (14) of FIGS. 1 and 2) may be coupled with a housing (205). For example, the cartridge (220) may be coupled to the body (210) with the cap (230) separated, and the cap (230) may be coupled to the body (210) to cover the cartridge (220).

In one embodiment, the cartridge (220) can accommodate an aerosol generating material having at least some of a liquid state, a solid state, a gaseous state, and a gel state. The cartridge (220) can be operated by an electric signal or a wireless signal transmitted from the main body, and can convert a phase of an aerosol generating material accommodated therein into a gaseous phase to generate an aerosol.

In one embodiment, an aerosol generated from an aerosol generating material in the cartridge (220) can pass through an aerosol opening (214) and travel along an aerosol path (216). The aerosol path (216) can deliver the aerosol to an elongated cavity (212), and the aerosol can pass through a stick inserted into the elongated cavity (212) and be delivered to a user.

In one embodiment, the aerosol generating unit (211) can generate an aerosol from an aerosol generating material. The aerosol generating unit (211) can generate the aerosol in various ways, for example, the aerosol generating unit (211) can adopt a heating method including a heater (218). Alternatively, the aerosol generating unit (211) can adopt an ultrasonic vibration method including a vibrator (not shown).

In one embodiment, a chamber (222) may be provided in the cartridge (220). The chamber (222) may contain and store an aerosol generating material therein. For example, the aerosol generating material may comprise a liquid composition. The liquid composition may be a liquid comprising a tobacco-containing material including a volatile tobacco flavoring component, or may be a liquid comprising a non-tobacco-containing material.

In one embodiment, the liquid composition contained inside the chamber (222) may be heated by the heater (218) to generate an aerosol, and the generated aerosol may be delivered to the user through a stick (e.g., the cigarette (2) of FIG. 1 or FIG. 2).

In one embodiment, the aerosol opening (214) may be provided on a surface of the body (210) facing the cartridge (220) (e.g., a surface in the -Z direction or the +Y direction). When the cartridge (220) is coupled with the body (210), the aerosol opening (214) may communicate with the chamber (222). The aerosol opening (214) may be an aerosol intake port of the aerosol path (216).

In one embodiment, the aerosol path (216) can be in communication with the elongated cavity (212) of the body (210) and the inlet (232). The aerosol path (216) can deliver aerosol from the chamber (222) to the inlet (232).

For example, aerosol generated in the chamber (222) by the aerosol generating unit (211) can pass through the aerosol opening (214), the aerosol path (216), and the elongated cavity (212) to the intake port (232).

In one embodiment, the aerosol generating unit (211) can generate an aerosol from an aerosol generating material. The aerosol generating unit (211) can generate the aerosol in various ways, for example, the aerosol generating unit (211) can adopt a heating method including a heater (218).

In one embodiment, a heater (218) may be disposed in the cartridge (220), for example, within the chamber (222) or opposite the chamber (222). The heater (218) may heat a liquid (liquid composition) contained within the chamber (222) to generate an aerosol. The heater (218) may include a wick and a coil. The coil may be rolled around the wick to generate heat.

In one embodiment, the aerosol generating device (200) may further include at least some of a processor (240) (e.g., the control unit (12) of FIGS. 1 and 2 or the control unit (110) of FIG. 3), a memory (245) (e.g., the memory (170) of FIG. 3), and a battery (247) (e.g., the battery (11) of FIGS. 1 and 2 or the battery (140) of FIG. 3).

In one embodiment, the processor (240) can control the operation of the aerosol generating device (200). For example, the processor (240) can control the operation state of the aerosol generating unit (211). The memory (245) is operatively connected to the processor (240) and can store executable instructions. The battery (247) can store power for operating the aerosol generating device (200) and provide it to components of the aerosol generating device (200).

In one embodiment, the input module (250) (e.g., the user input unit (160) of FIG. 3) may receive an input from a user and generate an input signal. The input module (250) may provide the generated input signal to the processor (240). The input module (250) may receive the input in various ways. For example, the input module (250) may be rotatably coupled to the housing (205) and may rotate around a rotation axis (R).

FIG. 5a is a perspective view of an input module (350) according to one embodiment, and FIG. 5b is a schematic diagram of an aerosol generating device (300) including an input module (350) according to one embodiment.

Referring to FIGS. 5A and 5B, an input module (350) according to one embodiment (e.g., the user (U) input unit (160) of FIG. 3 or the input module (250) of FIGS. 4A and 4B) may include a wheel (351), a plurality of markers (360), and a sensor unit (371) (e.g., the sensing unit (120) of FIG. 3).

In one embodiment, the wheel (351) may be rotatably disposed in the housing (305) (e.g., the housing (405) of FIGS. 4A and 4B) about a rotational axis (R). The wheel (351) may include an outer surface that is visually exposed to the exterior of the housing (305) and an inner surface that faces the housing (305) or is not visually exposed to the exterior of the housing (305).

In one embodiment, the outer surface of the wheel (351) may include a first surface (351a) (or, 'front surface') facing a direction (e.g., -Y direction) toward one side of the housing (305) in which the wheel (351) is disposed, and a second surface (351b) that is a surface (or, 'side surface') extending from an end of the first surface (351a) in a direction (e.g., +Y direction) toward the housing (305).

However, the shape, structure, size, and configuration of the wheel (351) depicted in the drawing are merely examples, and the actual implementation of the wheel (351) is not limited thereto. For example, the wheel (351) may have various geometric shapes such as a sphere, a hemisphere, a polygonal column, a cylinder, or an elliptical column.

In one embodiment, the plurality of markers (360) may be arranged on the outer surface of the wheel (351). For example, the plurality of markers (360) may be arranged on the first surface (351a) of the wheel (351). The plurality of markers (360) may have at least a portion of an area visually exposed to the first surface (351a) of the wheel (351). Alternatively, the plurality of markers (360) may be provided on the inside of the wheel (351), or may be provided on an inner surface facing the housing (305). Alternatively, the plurality of markers (360) may be arranged to penetrate from the first surface (351a) to an opposite surface. In the case where the plurality of markers (360) are not visually exposed to the outside, the wheel (351) may include a pattern or a protruding structure formed at a position corresponding to the plurality of markers (360).

In one embodiment, the plurality of markers (360) may be made of a conductive material or a metallic material. Alternatively, the plurality of markers (360) may have a different color, pattern, shape, height, or weight than the wheel (351), or the plurality of markers (360) may have different geometric or physical characteristics than the wheel (351).

In one embodiment, the plurality of markers (360) may include a first marker (361) and a second marker (362). The first marker (361) and the second marker (362) may be respectively arranged on the first surface (351a) of the wheel (351). However, the arrangement structure of the first marker (361) and the second marker (362) of FIG. 5A is merely an example, and the first marker (361) and the second marker (362) may have various structures and be arranged on the first surface (351a) in various arrangements.

In one embodiment, the sensor unit (371) can detect a change in the position of a plurality of markers (360) due to the rotation of the wheel (351). The sensor unit (371) can convert the detection result into an input signal and provide the input signal to the processor (340) (e.g., the control unit (12) of FIGS. 1 and 2, the control unit (110) of FIG. 3, or the processor (240) of FIG. 4b). The processor (340) can control the operation of the aerosol generating unit (311) (e.g., the aerosol generating unit (211) of FIG. 4b) based on the received input signal.

In one embodiment of the present document, a user (U) can intuitively, easily and conveniently control the operation of an aerosol generating device (300) (e.g., an aerosol generating device (1) of FIG. 1 or FIG. 2, an aerosol generating device (100) of FIG. 3 or an aerosol generating device (200) of FIGS. 4a and 4b) through a wheel (351).

For example, the user (U) can increase the driving period, intensity and/or power of the aerosol generating unit (311) by rotating the wheel (351) in a first rotational direction, or the user (U) can increase the driving period, intensity and/or power of the aerosol generating unit (311) by rotating the wheel (351) in a second rotational direction opposite to the first rotational direction.

Below, the configuration of an input module (350) according to one embodiment of the present document is described. This is an exemplary description, and the actual implementation of the input module (350) is not limited thereto, and at least some of the configurations may be modified, replaced, omitted, or added.

In one embodiment, each of the first marker (361) and the second marker (362) may have a linear structure. One end of each of the first marker (361) and the second marker (362) (e.g., the end in the -Z direction of FIG. 5A) may be in contact with each other, and the other end of each of the first marker (361) and the second marker (362) may be spaced apart from each other. Referring to FIG. 5A, the first marker (361) and the second marker (362) may be arranged in a 'V' shape on the first surface (351a) of the wheel (351).

In one embodiment, the sensor unit (371) may be positioned at a preset location to detect an encounter with one of the plurality of markers (360) and generate an input signal based on the detection result. Alternatively, the sensor unit (371) may include an optical sensor.

For example, the sensor unit (371) can generate a first facing signal when it faces the first marker (361), and the sensor unit (371) can generate a second facing signal when it faces the second marker (362). By the sensor unit (371) distinguishing and recognizing a plurality of markers (360), the processor (340) can predict the rotation direction of the wheel (351).

In one embodiment, the processor (340) can increase or decrease the power applied to the aerosol generating unit (311) based on the order and time at which the first and second facing signals are generated.

For example, a user (U) may grasp and rotate a first face (351a) and/or a second face (351b) of a wheel (351). As the wheel (351) rotates, the sensor unit (371) may face the first marker (361) and the second marker (362) and generate a first facing signal and a second facing signal. While the wheel (351) rotates one turn, the sensor unit (371) may generate two first facing signals and two second facing signals.

For example, when the sensor unit (371) is adjacent to a position where the ends of each of the first marker (361) and the second marker (362) are in contact as the wheel (351) rotates, the sensor unit (371) can generate the first facing signal and the second facing signal relatively quickly (or continuously). In addition, when the sensor unit (371) is adjacent to a position where the ends of each of the first marker (361) and the second marker (362) are spaced apart as the wheel (351) rotates, the sensor unit (371) can generate the first facing signal and the second facing signal relatively slowly (or at time intervals).

In one embodiment, the processor (340) can predict the rotation direction of the wheel (351) based on the order of the first facing signal and the second facing signal in a stage where the first facing signal and the second facing signal are generated quickly. Alternatively, the processor (340) can predict the rotation direction of the wheel (351) based on the order of the first facing signal and the second facing signal in a stage where the first facing signal and the second facing signal are generated slowly.

For example, based on the state of the input module (350) of FIG. 5A, when the wheel (351) rotates clockwise, the processor (340) may receive input signals in the following order: a first facing signal, a first facing signal, a second facing signal, a second facing signal, a waiting time, and then the first facing signal again. In addition, when the wheel (351) rotates counterclockwise, the processor (340) may receive input signals in the following order: a second facing signal, a second facing signal, a first facing signal, a first facing signal, a waiting time, and then the second facing signal again.

In one embodiment, the processor (340) can predict the rotation direction of the wheel (351) based on two facing signals received from the sensor unit (371) and the time interval between the facing signals. For example, the processor (340) can predict the rotation direction of the wheel (351) based on signals generated before and after a waiting time.

In one embodiment of this document, the input module (350) can recognize the rotational direction and rotational speed of the wheel (351) through a relatively simple configuration and structure. The processor (340) can control the operation of the aerosol generating unit (311) based on the input signal of the input module (350).

Figure 6 is a schematic diagram of an input module (350) according to one embodiment.

Referring to FIG. 6, a plurality of markers (360) according to one embodiment may include a first marker (361a) and a second marker (362a).

In the following, any content that overlaps with the above-described content will be omitted and explained, and it is obvious that some configurations and structures of the input module (350) may be replaced, added, or omitted within a range that can be easily understood by those skilled in the art by referring to the drawings and descriptions below. In addition, at least one configuration or feature of the above-described embodiments may be combined in the input module (350) unless it is technically clearly impossible.

In one embodiment, the first marker (361a) and the second marker (362a) may each have different shapes. For example, the first marker (361a) may have a '+' shape, and the second marker (362a) may have a '-' shape. By designing the shapes of the first marker (361a) and the second marker (362a) differently, the intuitiveness of the user (U) can be improved.

In one embodiment, a plurality of markers (360) may be arranged to be biased toward one side from the center on the outer surface of the wheel (351). For example, as illustrated in FIG. 6, a first marker (361a) and a second marker (362a) may be arranged to be biased toward one direction (e.g., +Z direction) from the center of the first surface (351a) of the wheel (351).

In one embodiment, the sensor unit (371) may be positioned at a preset location to detect an encounter with any one of a plurality of markers (360) and generate an input signal based on the detection result.

For example, the sensor unit (371) can generate a first facing signal when it faces the first marker (361a), and the sensor unit (371) can generate a second facing signal when it faces the second marker (362a). By the sensor unit (371) distinguishing and recognizing a plurality of markers (360), the processor (340) can predict the rotation direction of the wheel (351).

In one embodiment, the processor (340) can increase or decrease the power applied to the aerosol generating unit (311) based on the order and time at which the first and second facing signals are generated.

For example, a user (U) may grasp and rotate a first face (351a) and/or a second face (351b) of a wheel (351). As the wheel (351) rotates, the sensor unit (371) may face the first marker (361a) and the second marker (362a) and generate a first facing signal and a second facing signal. While the wheel (351) rotates one turn, one sensor unit (371) may generate one first facing signal and one second facing signal.

For example, when the sensor unit (371) is adjacent to a position where the first marker (361a) and the second marker (362a) are biased and arranged as the wheel (351) rotates, the sensor unit (371) can relatively quickly (or continuously) generate the first facing signal and the second facing signal. Thereafter, the sensor unit (371) can have a waiting time until the next first marker (361a) or second marker (362a) is recognized.

In one embodiment, the processor (340) can predict the rotation direction of the wheel (351) based on the order of the first facing signal, the second facing signal, and the waiting time.

For example, based on the state of the input module (350) of FIG. 6, when the wheel (351) rotates clockwise, the processor (340) may receive input signals in the order of a first facing signal, a second facing signal, a waiting time, and then the first facing signal again. In addition, when the wheel (351) rotates counterclockwise, the processor (340) may receive input signals in the order of a second facing signal, a first facing signal, a waiting time, and then the second facing signal again.

In one embodiment, the processor (340) can predict the rotation direction of the wheel (351) based on two facing signals received from the sensor unit (371) and the time interval between the facing signals. For example, the processor (340) can predict the rotation direction of the wheel (351) based on signals generated before and after a waiting time.

In one embodiment of this document, the input module (350) can recognize the rotational direction and rotational speed of the wheel (351) through a relatively simple configuration and structure. The processor (340) can control the operation of the aerosol generating unit (311) based on the input signal of the input module (350).

Figure 7 is a schematic diagram of an input module (350) according to one embodiment.

Referring to FIG. 7, a plurality of markers (360) according to one embodiment may include a first marker (361b), a second marker (362b), and a third marker (363b).

In the following, any content that overlaps with the above-described content will be omitted and explained, and it is obvious that some configurations and structures of the input module (350) may be replaced, added, or omitted within a range that can be easily understood by those skilled in the art by referring to the drawings and descriptions below. In addition, at least one configuration or feature of the above-described embodiments may be combined in the input module (350) unless it is technically clearly impossible.

In one embodiment, each of the first marker (361b) and the second marker (362b) may have a linear structure. One end (e.g., an end in the -Z direction) of each of the first marker (361b) and the second marker (362b) may be in contact with each other, and the other end of each of the first marker (361b) and the second marker (362b) may be spaced apart from each other.

In one embodiment, the third marker (363b) may have a linear structure. One end of the third marker (363b) may be in contact with a portion where the first marker (361b) and the second marker (362b) are in contact, and the other end of the third marker (363b) may extend in a direction (e.g., in the -Z direction) away from the first marker (361b) and the second marker (362b).

In one embodiment, the first marker (361b), the second marker (362b), and the third marker (363b) may have shapes that extend away from each other at equal intervals from a position where the first marker (361b), the second marker (362b), and the third marker (363b) contact each other. Referring to FIG. 7, the first marker (361b), the second marker (362b), and the third marker (363b) may be arranged on the first surface (351a) of the wheel (351) in a 'Y' shape.

In one embodiment, the sensor unit (371) may be positioned at a preset location to detect an encounter with any one of a plurality of markers (360) and generate an input signal based on the detection result.

For example, the sensor unit (371) can generate a first facing signal when it faces the first marker (361b), the sensor unit (371) can generate a second facing signal when it faces the second marker (362b), and the sensor unit (371) can generate a third facing signal when it faces the third marker (363b). Since the sensor unit (371) distinguishes and recognizes a plurality of markers (360), the processor (340) can predict the rotation direction of the wheel (351).

In one embodiment, the processor (340) can increase or decrease the power applied to the aerosol generating unit (311) based on the order in which the first facing signal, the second facing signal, and the third facing signal are generated.

For example, a user (U) may grasp and rotate a first face (351a) and/or a second face (351b) of a wheel (351). As the wheel (351) rotates, the sensor unit (371) may encounter a first marker (361b), a second marker (362b), and a third marker (363b), and generate a first facing signal, a second facing signal, and a third facing signal. While the wheel (351) rotates one turn, one sensor unit (371) may generate one first facing signal, one second facing signal, and one third facing signal.

In one embodiment, the processor (340) can predict the rotation direction of the wheel (351) based on the order of the first facing signal, the second facing signal, and the third facing signal.

For example, based on the state of the input module (350) of Fig. 7, when the wheel (351) rotates clockwise, the processor (340) may receive input signals in the order of a first facing signal, a third facing signal, a second facing signal, and then the first facing signal again. In addition, when the wheel (351) rotates counterclockwise, the processor (340) may receive input signals in the order of a second facing signal, a third facing signal, a first facing signal, and then the second facing signal again.

In one embodiment, the processor (340) can predict the rotation direction of the wheel (351) based on the order of three facing signals received from the sensor unit (371). For example, the processor (340) can predict the rotation direction of the wheel (351) based on signals generated before and after the waiting time.

In one embodiment of this document, the input module (350) can recognize the rotational direction and rotational speed of the wheel (351) through a relatively simple configuration and structure. The processor (340) can control the operation of the aerosol generating unit (311) based on the input signal of the input module (350).

Figure 8 is a schematic diagram of an input module (350) according to one embodiment.

Referring to FIG. 8, a plurality of markers (360) according to one embodiment may include a first marker (361c), a second marker (362c), and a third marker (363c).

In the following, any content that overlaps with the above-described content will be omitted and explained, and it is obvious that some configurations and structures of the input module (350) may be replaced, added, or omitted within a range that can be easily understood by those skilled in the art by referring to the drawings and descriptions below. In addition, at least one configuration or feature of the above-described embodiments may be combined in the input module (350) unless it is technically clearly impossible.

In one embodiment, each of the first marker (361c) and the second marker (362c) may have a linear structure. One end (e.g., an end in the -Z direction) of each of the first marker (361c) and the second marker (362c) may be in contact with each other, and the other end of each of the first marker (361c) and the second marker (362c) may be spaced apart from each other.

In one embodiment, the third marker (363c) may have a linear structure. One end of the third marker (363c) may be in contact with a portion where the first marker (361c) and the second marker (362c) are in contact, and the other end of the third marker (363c) may extend in a direction (e.g., in the -Z direction) away from the first marker (361c) and the second marker (362c).

In one embodiment, the first marker (361c) and the second marker (362c) may be arranged horizontally relative to each other, and the third marker (363c) may be arranged vertically relative to the first marker (361c) and the second marker (362c). Referring to FIG. 8, the first marker (361c), the second marker (362c), and the third marker (363c) may be arranged in a 'T' shape on the first surface (351a) of the wheel (351).

In one embodiment, the sensor unit (371) may be positioned at a preset location to detect an encounter with any one of a plurality of markers (360) and generate an input signal based on the detection result.

For example, the sensor unit (371) can generate a first facing signal when it faces the first marker (361c), the sensor unit (371) can generate a second facing signal when it faces the second marker (362c), and the sensor unit (371) can generate a third facing signal when it faces the third marker (363c). Since the sensor unit (371) distinguishes and recognizes a plurality of markers (360), the processor (340) can predict the rotation direction of the wheel (351).

In one embodiment, the processor (340) can increase or decrease the power applied to the aerosol generating unit (311) based on the order in which the first facing signal, the second facing signal, and the third facing signal are generated.

For example, a user (U) may grasp and rotate a first face (351a) and/or a second face (351b) of a wheel (351). As the wheel (351) rotates, the sensor unit (371) may face a first marker (361c), a second marker (362c), and a third marker (363c), and generate a first facing signal, a second facing signal, and a third facing signal. While the wheel (351) rotates one turn, one sensor unit (371) may generate one first facing signal, one second facing signal, and one third facing signal.

In one embodiment, the processor (340) can predict the rotation direction of the wheel (351) based on the order of the first facing signal, the second facing signal, and the third facing signal.

For example, based on the state of the input module (350) of FIG. 8, when the wheel (351) rotates clockwise, the processor (340) may receive input signals in the order of a first facing signal, a third facing signal, a second facing signal, and then the first facing signal again.
