[0025] The terms used in the embodiments are selected from widely used, common terms, taking into account their functions. However, these terms may vary depending on the intentions of those skilled in the art, precedents, the emergence of new technologies, etc. Furthermore, in certain cases, the applicant may arbitrarily select terms, and in such cases, their meanings will be described in detail in the description of the relevant invention. Therefore, the terms used in the present invention should not be defined simply as names of terms, but rather based on their meanings and the overall content of the present invention.

[0026] When a part of the specification is said to "include" a component, this does not exclude other components, but rather implies the inclusion of other components, unless otherwise specifically stated. Furthermore, terms such as "-unit" and "-module" used in the specification refer to a unit that processes at least one function or operation, which may be implemented in hardware, software, or a combination of hardware and software.

[0027] As used herein, when an expression such as "at least one" precedes an array of elements, it modifies the entire array of elements, not just each individual element. For example, the expression "at least one of a, b, and c" should be interpreted to include a, b, c, or a and b, a and c, b and c, or a and b and c.

[0028] Figure 1 is a perspective view of an inhaler system (1) according to one embodiment.

[0029] Referring to FIG. 1, an inhaler system (1) according to one embodiment can deliver a functional substance to a user, for example, the inhaler system (1) according to one embodiment can be configured as an inhaler that delivers nicotine to the user's lungs in the form of an aerosol.

[0030] In one embodiment, the inhaler system (1) may include a functional material receiving article (S) and an inhaler (10).

[0031] The functional material receiving article (S) may be configured in the form of a stick. The stick may be configured in a cylindrical shape that can be inserted into an inhaler (10).

[0032] A functional material-containing article (S) may include a plurality of segments along a longitudinal direction (e.g., the ±Z direction in FIG. 1). A capsule may be contained in one of the plurality of segments. The segment containing the capsule may be configured as a cavity. For example, the capsule may be contained so as to be freely rotatable within the cavity, which may facilitate the functional material within the capsule to be easily removed from the capsule.

[0033] The front segment of the segment that accommodates the capsule may be composed of a cellulose acetate material. The front segment may prevent leakage of the functional material powder. The rear segment of the segment that accommodates the capsule may be composed of a mouthpiece segment that contacts the user's mouth. The segment that accommodates the capsule and the mouthpiece segment may be connected to enable communication of the functional material and air.

[0034] The capsule may contain a functional material. For example, the functional material may include at least one of nicotine, theanine, caffeine, taurine, a pharmacological agent, or a mixture thereof. The functional material may be in the form of fine granules or dry powder. In one example, the outer shell of the capsule may be composed of a material that can be penetrated or cut by a needle (300). For example, the capsule may be filled with a functional material in an amount corresponding to the user's inhalation of 10 to 14 puffs.

[0035] A functional substance-containing article (S) can be inserted into an inhaler (10). The capsule of the functional substance-containing article (S) contained in the inhaler (10) can be cut or crushed. At this time, the functional substance can be released from the capsule and inhaled by the user through the mouthpiece segment together with air introduced into the front segment of the functional substance-containing article (S).

[0036] Fig. 2a is a perspective view of an inhaler (10) according to one embodiment, and Fig. 2b is a cross-sectional view taken along line AA of Fig. 2a. Fig. 3a shows an inhaler (10) according to one embodiment without a housing (100), and Fig. 3b shows a sliding structure (200) of the inhaler (10) according to one embodiment.

[0037] Referring to FIGS. 2a and 2b, an inhaler (10) according to one embodiment may include a housing (100), a sliding structure (200), a needle (300), and an elastic body (400).

[0038] In one embodiment, the housing (100) may include a first surface (101), a second surface (102) opposite the first surface (101), and a side surface (103) between the first surface (101) and the second surface (102).

[0039] An insertion space (104) into which a functional material receiving article (S) is inserted may be formed on a first surface (101) of the housing (100). An air inlet (100H) communicating with the insertion space (104) may be formed on the housing (100). For example, the air inlet (100H) may be provided on a side surface (103) of the housing (100). A plurality of air inlets (100H) may be configured, and the plurality of air inlets (100H) may be arranged at equal intervals along the periphery of the side surface (103).

[0040] In one embodiment, the sliding structure (200) can be accommodated within the housing (100). The sliding structure (200) can move along a longitudinal direction (e.g., ±Z direction in FIG. 2a) connecting the first surface (101) and the second surface (102).

[0041] An elastic body (400) may be accommodated within the housing (100). The elastic body (400) may be positioned between the sliding structure (200) and the second surface (102) of the housing (100) to apply an elastic force to the sliding structure (200) toward the first surface (e.g., toward the +Z direction in FIG. 2b). For example, the elastic body (400) may include a coil spring.

[0042] In one embodiment, the needle (300) may be accommodated within the housing (100). One end of the needle (300) may be fixed to the second surface (102) of the housing (100), and the other end (tip) of the needle (300) may protrude toward the insertion space (104) of the housing (100).

[0043] For example, the needles (300) may be configured in multiples. In particular, referring to FIG. 3A, two needles (300) may be arranged in parallel along the longitudinal direction (e.g., the Z direction). When two needles (300) are inserted into the functional material-containing article (S), the functional material-containing article (S) can be prevented from rotating within the insertion space (104).

[0044] The needle (300) can penetrate the sliding structure (200). In particular, referring to FIG. 3b, the sliding structure (200) can be provided with a needle hole (250) that penetrates the sliding structure (200) in the longitudinal direction (e.g., Z direction), and the needle (300) can extend through the sliding structure (200) through the needle hole (250).

[0045] Referring to FIGS. 3a and 3b, the sliding structure (200) may include a sliding body (210), a recessed part (220), a protruding part (230), a settling part (240), and an airflow hole (200H).

[0046] The sliding body (210) may include a first sliding surface (211) facing the first side (101) of the housing (100), a second sliding surface (212) on the opposite side of the first sliding surface (211), and a sliding side surface (213) between the first sliding surface (211) and the second sliding surface (212).

[0047] The sliding side surface (213) may be configured in a step shape. The upper sliding side surface (213) adjacent to the first sliding side surface (211) may have a wider width than the lower sliding side surface (213) adjacent to the second sliding side surface (212). Referring also to FIG. 2b, the upper sliding side surface (213) may be in contact with the inner wall of the housing (100), and the lower sliding side surface (213) may be spaced apart from the inner wall of the housing (100).

[0048] The airflow hole (200H) can be formed on the lower sliding side surface (213). Since the airflow hole (200H) is located on the lower sliding side surface (213), external air passing through the air inlet (100H) of the housing (100) can easily enter the airflow hole (200H) without being obstructed by the inner wall of the housing (100).

[0049] The recess part (220) may have a structure that is sunken from the first sliding surface (211). The recess part (220) may include a recess base (221) that is sunken from the first sliding surface (211) to the second sliding surface (212) and a recess side surface (223) that extends from the recess base (221) to the first sliding surface (211). An upper portion of the recess part (220) (e.g., an upper portion in the +Z direction in FIG. 3b) may be an open space.

[0050] The needle hole (250) can be formed by penetrating from the recess base (221) to the second sliding surface (212).

[0051] The airflow hole (200H) can be formed by penetrating from the sliding side surface (213) to the recess side surface (223).

[0052] The protruding part (230) can protrude from the first sliding surface (211) toward the first surface (101) of the housing (100). The protruding part (230) can be positioned on the outside of the recessed part (220).

[0053] For example, the protruding parts (230) may be configured in plurality. The plurality of protruding parts (230) may be arranged to be spaced apart from the recessed part (220) at equal distances outwardly (e.g., in the ±X direction or ±Y direction in FIG. 3b). A functional material-accommodating article (S) may be introduced into a region formed by being surrounded by the protruding parts (230). At this time, the movement of the functional material-accommodating article (S) in the outward direction (e.g., in the ±X direction or ±Y direction in FIG. 3b) may be restricted by the protruding parts (230).

[0054] The settling part (240) can be placed between the protruding part (230) and the recessed part (220). The settling part (240) can be defined as the area of ​​the first sliding surface (211) between the protruding part (230) and the recessed part (220).

[0055] The diameter of the area formed by being surrounded by the protruding parts (230) may be larger than the diameter of the upper area of ​​the recessed part (220) on the same plane as the first sliding surface (211). Meanwhile, the diameter of the area formed by being surrounded by the protruding parts (230) may be larger than the diameter of the front end of the functional material-accommodating article (S) (e.g., the diameter in the XY plane). The diameter of the upper area of ​​the recessed part (220) may be smaller than the diameter of the front end of the functional material-accommodating article (S). By this relationship, the front end of the functional material-accommodating article (S) can be mounted on the mounting part (240). In addition, a part of the front end of the functional material-containing article (S) may be exposed to the recess part (220), and the front end of the functional material-containing article (S) and the outlet (200HO) of the airflow hole (200H) may be spaced apart, and air coming out of the outlet (200HO) of the airflow hole (200H) may form a vortex in the recess part (220) and then enter the functional material-containing article (S). The formation of the vortex will be described later.

[0056] In one embodiment, a virtual line connecting the inlet (200HI) of the airflow hole (200H) formed on the sliding side surface (213) and the outlet (200HO) of the airflow hole (200H) formed on the recess side surface (223) may be deflected from the center of the sliding body (210) (e.g., the center of the recess base (221)). If the airflow hole (200H) is formed diagonally (formed so as to face a tangential direction) rather than toward the center of the recess base (221), a vortex may be formed within the recess part (220) as the air entering the airflow hole (200H) exits through the outlet (200HO) of the airflow hole (200H). The vortex formed in this way may enter the functional material containing article (S) and cause rotation and vibration of the capsule. By the rotation and vibration of the capsule, the functional material contained in the capsule can easily escape from the capsule.

[0057] A plurality of airflow holes (200H) can be arranged at equal intervals around the periphery of the recess part (220). Each of the airflow holes (200H) can be arranged to face in a diagonal direction (tangential direction).

[0058] In one embodiment, the area of ​​the outlet (200HO) of the airflow hole (200H) may be smaller than the area of ​​the inlet (200HI) of the airflow hole (200H). Air entering the inlet (200HI) of the airflow hole (200H) may be accelerated due to the area gradually narrowing as it moves toward the outlet (200HO) of the airflow hole (200H). The air velocity when exiting the outlet (200HO) of the airflow hole (200H) may be faster than the air velocity when entering the inlet (200HI) of the airflow hole (200H). The faster air velocity may facilitate the formation of a vortex more smoothly.

[0059] For example, the airflow hole (200H) can be extended in a straight line. The airflow hole (200H) can be formed along an imaginary straight line connecting the inlet (200HI) and the outlet (200HO) of the airflow hole (200H). The straight-shaped airflow hole (200H) can increase the convenience of processing the airflow hole (200H).

[0060] As another example, the airflow hole (200H) can be extended in a curved shape. The curved shape of the airflow hole (200H) can bend the flow of air entering the recess part (220), so that a vortex can be formed more smoothly along the recess side surface (223).

[0061] Hereinafter, the operation of the inhaler system (1) according to one embodiment will be described with reference to FIGS. 1, 2a, 2b 3a and 3b.

[0062] A functional material-containing article (S) is inserted into an insertion space (104) of a housing (100) of an inhaler (10), and a front end of the functional material-containing article (S) can be seated on a seating part (240) of a sliding body (210). At this time, a needle (300) can be inserted into at least a portion of the functional material-containing article (S).

[0063] In this state, if the functional material-containing article (S) is continuously inserted into the insertion space (104), the sliding body (210) together with the functional material-containing article (S) can move toward the second surface (102) of the housing (100) (e.g., toward the -Z direction). At this time, the capsule within the functional material-containing article (S) can be crushed or cut by the needle (300), and the functional material contained within the capsule can be exposed outside the capsule.

[0064] When the force applied to the functional material-containing article (S) is removed, the sliding structure (200) returns to its original position by the elastic body (400), and the functional material-containing article (S) can also move together with the sliding structure (200). When the sliding structure (200) completes returning to its original position, the functional material-containing article (S) can remain in a state in which a portion of the functional material-containing article is inserted into the housing (100) while being seated on the sliding structure (200). In this state, the user can inhale the functional material while biting the mouthpiece segment of the functional material-containing article (S) with his or her mouth.

[0065] When the user starts inhaling, negative pressure is formed in the recessed part (220) of the sliding structure (200) through the mouthpiece segment. Due to the negative pressure in the recessed part (220), air outside the housing (100) can be introduced into the recessed part (220) through the air inlet (100H) and the airflow hole (200H). At this time, due to the structure and arrangement of the airflow hole (200H), the air can be introduced into the recessed part (220) in a diagonal direction (tangential direction), and a vortex airflow can be formed within the recessed part (220). This vortex airflow can be introduced into the functional material containing article (S) to induce rotation and vibration of the capsule. The functional material smoothly exiting the capsule due to the rotation and vibration of the capsule can be inhaled by the user through the mouthpiece segment.

[0066] Fig. 4 shows another example of a sliding structure of an inhaler according to one embodiment. Among the components of the sliding structure (200A) according to Fig. 4, descriptions of components identical or similar to those of the sliding structure (200) in Figs. 2a to 3b will be omitted for simplicity.

[0067] Referring to FIG. 4, the sliding structure (200A) may include a sliding body (210A), a recessed part (220A), a protruding part (230A), a settling part (240A), an airflow hole (200AH), and an impeller (500).

[0068] In one embodiment, the impeller (500) may be formed in the recess base (221A). The impeller (500) may extend from the recess side surface (223A) to the center of the recess base (221A). The impeller (500) may be positioned so as not to interfere with the needle hole (250A).

[0069] The impeller (500) may be configured in multiples, and the outlet (200AHO) of the airflow hole (200AH) may be located between adjacent impellers (500).

[0070] An imaginary line connecting the inlet (200AHI) of the airflow hole (200AH) formed on the sliding side surface (213A) and the outlet (200AHO) of the airflow hole (200AH) formed on the recess side surface (223A) may be deflected from the center of the sliding body (210A) (e.g., the center of the recess base (221A)). If the airflow hole (200AH) is formed diagonally (formed so as to face the tangential direction) rather than toward the center of the recess base (221A), a vortex may be formed within the recess part (220A) as the air entering the airflow hole (200AH) exits through the outlet (200AHO) of the airflow hole (200AH). At this time, the air that has escaped through the outlet (200AHO) of the airflow hole (200AH) passes through the impeller (500) once more, so that the formation of a vortex can become smoother.

[0071] The impeller (500) may have a curved shape. More specifically, the impeller (500) may have a blade or plate shape that curves from the recess side surface (223A) toward the recess base (221A).

[0072] In one embodiment, the gap between the adjacent impellers (500) may become narrower from the recess side surface (223A) toward the center of the recess base (221A). Air exiting from the outlet (200AHO) of the airflow hole (200AH) may be accelerated due to the area gradually narrowing as it passes through the impeller (500). The air flow rate when exiting the impeller (500) may be faster than the air flow rate when exiting the outlet (200AHO) of the airflow hole (200AH). The faster air flow rate may facilitate the formation of a vortex more smoothly.

[0073] Fig. 5 shows another example of a sliding structure of an inhaler according to one embodiment. Among the components of the sliding structure (200B) according to Fig. 5, descriptions of components that are identical or similar to the components of the sliding structure (200) in Figs. 2a to 3b will be omitted for simplicity.

[0074] Referring to FIG. 5, the sliding structure (200B) may include a sliding body (210B), a recessed part (220B), a protruding part (230B), a settling part (240B), an airflow hole (200BH), and an airflow guide (600).

[0075] In one embodiment, the airflow guide (600) may be a structure that protrudes upward (toward the +Z direction) from the center of the recess base (221B). The airflow guide (600) may guide the vortex formed within the recess part (220B) to the functional material receiving article (S).

[0076] Air that escapes from the outlet (200BHO) of the airflow hole (200BH) can collide with the airflow guide (600) as it gathers at the center of the recess part (220B). The air that collides with the airflow guide (600) can be smoothly guided upward along the outer surface of the airflow guide (600). The air that escapes the airflow guide (600) can enter the functional material receiving article (S).

[0077] According to an embodiment of the inhaler (10) and the inhaler system (1) including the same, it is possible to induce smooth discharge of a functional material and smoothly induce vortex behavior of air moving toward a functional material-containing article. In addition, in implementing tangential inflow of air, it is not necessary to form a tangential airflow hole in the functional material-containing article (S), and thus it is possible to have the advantage of not requiring complex manufacturing equipment.

[0078] In one embodiment, an inhaler (10) may be inserted with a functional material-containing article (S) that contains a functional material. The above inhaler (10) includes a housing (100) including a first surface (101), a second surface (102) opposite to the first surface (101), and a side surface (103) between the first surface (101) and the second surface (102), and forming an insertion space (104) into which the functional material-containing article (S) is inserted from the first surface (101), a sliding structure (200) accommodated in the housing (100) and movable along the longitudinal direction connecting the first surface (101) and the second surface (102), and a needle (300) accommodated in the housing (100) and protruding from the second surface (102) toward the first surface (101), and an air inlet (100H) communicating with the insertion space (104) is formed in the housing (100), Air outside the housing (100) can move through the air inlet (100H) and the sliding structure (200) to the functional material receiving article (S).

[0079] In one embodiment, the sliding structure (200) includes a sliding body (210) on which the functional material receiving article (S) is mounted and which is movable along the longitudinal direction, and an airflow hole (200H) formed in the sliding body (210), and the sliding body (210) may include a first sliding surface (211) facing the first surface (101), a second sliding surface (212) on the opposite side of the first sliding surface (211), and a sliding side surface (213) between the first sliding surface (211) and the second sliding surface (212).

[0080] The sliding structure (200) further includes a recessed part (220) sunken from the first sliding surface (211), a protruding part (230) protruding from the first sliding surface (211) and positioned outside the recessed part (220), and a mounting part (240) between the recessed part (220) and the protruding part (230), and the recessed part (220) includes a recessed base (221) and a recessed side surface (223) extending from the recessed base (221) to the first sliding surface (211), and the airflow hole (200H) can be formed to penetrate from the sliding side surface (213) to the recessed side surface (223).

[0081] A virtual line connecting the inlet (200HI) of the airflow hole (200H) located on the sliding side surface (213) and the outlet (200HO) of the airflow hole (200H) located on the recess side surface (223) can be deflected from the center of the sliding body (210).

[0082] In one embodiment, the area of ​​the outlet (200HO) of the airflow hole (200H) may be smaller than the area of ​​the inlet (200HI) of the airflow hole (200H).

[0083] In one embodiment, the airflow hole (200H) may extend in a straight line.

[0084] In one embodiment, the airflow hole (200H) may extend in a curved shape.

[0085] The sliding structure (200A) according to one embodiment may further include an impeller (500) formed in the recess base (221A).

[0086] The above impeller (500) can extend from the recess side surface (223A) to the center of the recess base (221A).

[0087] The above impeller (500) is configured in plurality, and an outlet (200AHO) of an airflow hole (200AH) can be located between adjacent impellers (500).

[0088] The above impeller (500) may have a curved shape.
