[0033] In the present disclosure, the direction of the inhaler may be defined with respect to an orthogonal coordinate system. In the orthogonal coordinate system, the x-axis direction may be defined as the left-right direction of the inhaler. The y-axis direction may be defined as the front-back direction of the inhaler. The z-axis direction may be defined as the up-down direction of the inhaler.

[0034] FIG. 1 is a perspective view of an inhaler (10) according to one embodiment. FIG. 2 shows the structure of an inhaler (10) according to one embodiment, FIG. 3 shows the internal structure of the housing (110) of an inhaler (10) according to one embodiment, and FIG. 4 shows the internal structure of the housing (110) of an inhaler (10) according to one embodiment. FIG. 5 shows the cartridge (120) of an inhaler (10) according to one embodiment, and FIG. 6 shows the airflow of an inhaler (10) according to one embodiment.

[0035] Referring to FIGS. 1 to 3, an inhaler (10) according to one embodiment can deliver a functional substance to a user. The functional substance may have the form of fine granules or dry powder. For example, an inhaler (10) according to one embodiment may be configured as a dry powder inhaler that delivers dry powder to the user's lungs.

[0036] For example, the size of the dry powder that can be inhaled through the inhaler (10) may be configured in a mixed form of inhalation powder of approximately 1 µm to 5 µm and a carrier of 10 µm to 50 µm or less. Alternatively, the dry powder that can be inhaled through the inhaler (10) may be used as a dry powder for inhalation of approximately 1 µm to 5 µm alone.

[0037] For example, types of powders that can be applied as functional substances for inhalation may include nicotine salts such as nicotine, nicotine tartrate, nicotine lactate, and nicotine citrate, or other functional substances such as caffeine. Alternatively, they may be substances capable of producing other pharmacological effects.

[0038] For example, types of powders that can be applied as carrier materials may include powders containing lactose, menthol, peppermint, or other powders in which essential fragrance oils are powdered.

[0039] Substances that can be used as carriers may include alpha-lactose monohydrated, beta-cyclodextrin, maltodextrin, mannitol, etc., or may be in a form in which the above excipients are appropriately mixed. In addition, the above excipients and other small amounts of excipients such as saccharin and xylitol may be included.

[0040] An inhaler (10) according to one embodiment may include a housing (110), a cartridge (120), a vortex-forming structure (130), an air guide plate (140), and a mouthpiece (150).

[0041] The housing (110) may include a first housing (1110) and a second housing (1120). A mouthpiece (150) may be formed protruding from the first housing (1110). The second housing (1120) may be coupled to the first housing (1110) on the opposite side of the mouthpiece (150). For example, the first housing (1110) and the second housing (1120) may be formed integrally.

[0042] The width of the second housing (1120) may be greater than the width of the first housing (1110). The width of the housing (110) may be defined in a direction perpendicular to the longitudinal direction (e.g., Z direction in FIG. 1) in which the first housing (1110) and the second housing (1120) are arranged (e.g., X direction or Y direction in FIG. 1). For example, in the direction viewed from the first housing (1110) toward the second housing (1120), the second housing (1120) may have an upper portion (1120A) having a width greater than that of the first housing (1110).

[0043] In one embodiment, the housing (110) may include an opening (1101), a cartridge receiving space (1102), an air passage (1103), an air inlet (1104), and an air outlet (1105).

[0044] An opening (1101) may be formed in the second housing (1120) on the opposite side of the first housing (1110). A cartridge (120) may be inserted into the second housing (1120) through the opening (1101).

[0045] For example, the opening (1101) may have a shape corresponding to the cross-section of at least a portion of the cartridge (120) (e.g., the first body (1210) of the cartridge in FIG. 5). The cartridge (120) inserted into the opening (1101) may be coupled to the second housing (1120).

[0046] The cartridge receiving space (1102) may be defined as a space formed by being recessed from the opening (1101). The cartridge receiving space (1102) may be formed inside the second housing (1120). At least a portion of the cartridge receiving space (1102) may be a space having a shape corresponding to the outer shape of at least a portion of the cartridge (120) (e.g., the first body of the cartridge (1210) in FIG. 5).

[0047] For example, the cartridge (120) can be fitted into the cartridge receiving space (1102) in a tight fit manner.

[0048] As another example, if the inner wall of the cartridge receiving space (1102) and at least a part of the cartridge (120) (e.g., the first body of the cartridge in FIG. 5 (1210)) are configured in a cylindrical shape, a threaded structure may be formed on one of them and a threaded structure corresponding to the threaded structure may be formed on the other, and the cartridge (120) may be coupled to the cartridge receiving space (1102) by a screw connection.

[0049] The air passage (1103) may be a through hole formed inside the first housing (1110). The air passage (1103) may penetrate the first housing (1110) in the longitudinal direction (e.g., Z direction in FIG. 3). The air passage (1103) may extend from the cartridge receiving space (1102) to the upper part (1110A) of the first housing (1110) where the mouthpiece (150) is placed. Air from the cartridge receiving space (1102) may be delivered to the mouthpiece (150) through the air passage (1103).

[0050] An air inlet (1104) may be formed on the outside of the housing (110). For example, the air inlet (1104) may be formed on the upper part (1120A) of the second housing (1120). By positioning the air inlet (1104) on the upper part (1120A) of the second housing (1120), the air inlet (1104) may not be blocked even when the user grasps the side of the first housing (1110) or the side of the second housing (1120). Meanwhile, since the air inlet (1104) is oriented toward the top, leakage of the functional material contained within the cartridge (120) can be effectively prevented. Furthermore, the air inlet (1104) may not be easily visible from the outside of the housing (110), thereby enhancing the aesthetic appeal of the inhaler (10).

[0051] The air inlets (1104) may be configured in multiple numbers. Multiple air inlets (1104) may be arranged with the first housing (1110) in between.

[0052] The air outlet (1105) may be formed to be exposed to the cartridge receiving space (1102). The air outlet (1105) may be formed on the inner wall of the second housing (1120) defining the cartridge receiving space (1102). The air outlet (1105) may be in communication with the air inlet (1104).

[0053] In particular, with reference to FIG. 3, the air inlet passage extending from the air inlet (1104) to the air outlet (1105) may include at least one bent portion. Since at least a portion of the air inlet passage is bent, the functional material of the cartridge (120) cannot easily come out through the air inlet (1104) even if it is introduced into the air outlet (1105). Meanwhile, the functional material may accumulate in the bent portion of the air inlet passage, and the accumulated functional material may be discharged back into the air outlet (1105) by the air introduced through the air inlet (1104).

[0054] In one embodiment, the air inlet (1104) or the air outlet (1105) may be formed with a size to achieve appropriate suction resistance. For example, the cross-section of the air inlet (1104) or the air outlet (1105) may be set to a horizontal length of 0.5 mm, 1.0 mm, 1.5 mm, or 2 mm, or to a vertical length of 0.5 mm, 1.0 mm, 1.5 mm, or 2 mm. Alternatively, the area of ​​the air inlet (1104) or the air outlet (1105) may be 0.25 mm 2 , 0.5mm 2 , 1mm 2 , 2mm 2 , 4mm 2 It can be set to any one of the following.

[0055] In one embodiment, the suction device (10) may further include an air inlet cap that opens and closes the air inlet (1104). The air inlet cap can block the air inlet (1104) when the suction device (10) is not in use, thereby blocking the inflow of external substances.

[0056] Meanwhile, the air inlet cap can open and close at least a portion of the air inlet (1104) so ​​that the degree of opening of the air inlet (1104) is variable. By controlling the degree of opening of the air inlet (1104) with the air inlet cap, the suction resistance can be controlled. Meanwhile, if the air inlet (1104) is composed of multiple air inlets, the air inlet cap may be composed of a number corresponding to the number of multiple air inlets (1104). In this case, the suction resistance can be easily controlled by closing only a portion of the multiple air inlets (1104).

[0057] In one embodiment, the mouthpiece (150) may have a circular or square cross-sectional shape. For example, the mouthpiece (150) may be implemented in a cylindrical shape having an outer diameter similar to the diameter of a conventional cigarette. For example, the outer diameter of the mouthpiece (150) may be 6 mm to 8 mm.

[0058] The inner diameter of the mouthpiece (150) may be sufficiently small compared to the outer diameter. For example, the inner diameter of the mouthpiece (150) may be any one of 4 mm, 5 mm, 6 mm, or 7 mm.

[0059] A mouthpiece cap can cover the mouthpiece (150). The mouthpiece cap can block external substances from entering the mouthpiece (150) when the inhaler (10) is not in use.

[0060] In one embodiment, a mesh screen may be provided at the front end of the mouthpiece (150). The mesh screen may provide additional suction resistance. Additionally, the mesh screen may cause separation through physical collision between the suction powder and the carrier.

[0061] Referring to FIG. 5, the cartridge (120) can accommodate an inhalable functional material. In one example, the cartridge (120) can be attached to the housing (110). In another example, the cartridge (120) can be fixed to the housing (110).

[0062] In one embodiment, the cartridge (120) may include a cartridge first body (1210), a cartridge second body (1220), a cartridge internal space (1202), a cartridge base (1206), and a cartridge inner wall (1207).

[0063] The width of the first cartridge body (1210) may be smaller than the width of the second cartridge body (1220). The width of the cartridge (120) may be defined in a direction perpendicular to the longitudinal direction (e.g., Z direction in FIG. 5) in which the first cartridge body (1210) and the second cartridge body (1220) are arranged (e.g., X direction in FIG. 5). For example, in the direction viewed from the first cartridge body (1210) toward the second cartridge body (1220), the second cartridge body (1220) may have an upper portion having a width greater than that of the first cartridge body (1210).

[0064] The first cartridge body (1210) may have a cross-section corresponding to the opening (1101) of the housing (110). The first cartridge body (1210) may have an external shape corresponding to the cartridge receiving space (1102) of the housing (110). The first cartridge body (1210) may be inserted into the cartridge receiving space (1102).

[0065] The upper part of the cartridge second body (1220) may have a larger area than the opening (1101) of the housing (110), so that the cartridge second body (1220) is not inserted into the opening (1101) and may be exposed from the lower part of the housing (110) (e.g., the -Z direction side of FIG. 2).

[0066] The cartridge internal space (1202) may be defined as a space formed inside the cartridge first body (1210) and the cartridge second body (1220). A functional substance may be accommodated in the cartridge internal space (1202). For example, the cartridge internal space (1202) may be configured to be a space for storing approximately 30 mg, 50 mg, 100 mg, 300 mg, 600 mg, or 1000 mg of a functional substance.

[0067] The upper part of the cartridge internal space (1202) may be open, and the cartridge internal space (1202) may be sealed by a cover. For example, the cover may be a thin film that can be removed by a user or easily torn when combined with the housing (110).

[0068] The cartridge base (1206) is located at the bottom of the cartridge internal space (1202), and the cartridge inner wall (1207) may be in contact with the edge of the cartridge base (1206). At least a portion of the cartridge inner wall (1207) may be configured to be inclined toward the center of the cartridge base (1206). At least a portion of the cartridge inner wall (1207) may be configured to have an angle corresponding to the inclined angle of the air guide plate (140). By having the cartridge inner wall (1207) have a shape inclined toward the inside of the cartridge internal space (1202), the functional material can be easily guided toward the center of the cartridge internal space (1202), and the amount of functional material remaining in the cartridge internal space (1202) can be minimized.

[0069] Again, referring to FIGS. 1 to 3, an air guide plate (140) can be placed between an air outlet (1105) and an air passage (1103).

[0070] In one embodiment, the air guide plate (140) may be a plate extending from the inner wall of the second housing (1120) toward the opening (1101). In particular, referring to FIG. 2, the air guide plate (140) may be configured to have a length that does not come into contact with the cartridge (120) (e.g., cartridge base (1206)).

[0071] The air guide plate (140) can guide air coming out of the air outlet (1105) into the center of the cartridge internal space (1202). The air can be guided into the functional material contained in the cartridge internal space (1202).

[0072] The air guide plate (140) may be configured to be inclined toward the center of the opening (1101). As previously described, the angle at which the cartridge inner wall (1207) is inclined and the angle at which the air guide plate (140) is inclined may correspond to each other. For example, the angle at which the cartridge inner wall (1207) is inclined and the angle at which the air guide plate (140) is inclined may be substantially the same.

[0073] In one embodiment, the air guide plate (140) may include a first air guide plate (1410) and a second air guide plate (1420). The first air guide plate (1410) and the second air guide plate (1420) may each be positioned facing each other in a tilted state toward the center of the opening (1101).

[0074] The first air guide plate (1410) and the second air guide plate (1420) may be spaced apart and may not come into contact with each other. Air introduced into the cartridge internal space (1202) through the space between the first air guide plate (1410) and the second air guide plate (1420) can move toward the air passage (1103).

[0075] In one embodiment, the air guide plates (140) may be configured in a number corresponding to the number of air outlets (1105). The air guide plates (140) are arranged in pairs adjacent to the air outlets (1105), so that air to be introduced into the cartridge internal space (1202) through the air outlets (1105) is guided to the cartridge base (1206) and can move to the air passage (1103) together with the functional material.

[0076] By the structure in which the air guide plate (140) divides the outer and central parts of the cartridge internal space (1202) and is inclined toward the center of the cartridge internal space (1202), the functional material contained in the cartridge internal space (1202) can be completely consumed without leaving any residue.

[0077] Referring to FIGS. 3 and 4, a vortex-forming structure (130) may be placed in an air passage (1103). The vortex-forming structure (130) may be placed in at least a portion of the air passage (1103) to induce vortex behavior of the air passing through the air passage (1103). Due to the vortex behavior of the air passing through the vortex-forming structure (130), the functional material may be delivered to the user in a uniformly mixed state.

[0078] In one embodiment, the vortex-forming structure (130) may include a vortex-forming cylinder (1310) and a vortex-forming spiral guide (1320). The vortex-forming cylinder (1310) may be positioned in the center of the air passage (1103). The vortex-forming spiral guide (1320) may be positioned between the vortex-forming cylinder (1310) and the inner wall defining the air passage (1103).

[0079] The vortex-forming cylinder (1310) may include a cylindrical body and hemispherical upper and lower portions coupled to the body.

[0080] The diameter of the body of the vortex-forming cylinder (1310) may be smaller than the inner diameter of the air passage (1103). By having the upper and lower parts of the vortex-forming cylinder (1310) have a hemispherical shape, the resistance of the vortex-forming cylinder (1310) to the air flowing into the air passage (1103) can be minimized.

[0081] The vortex-forming spiral guide (1320) is a plate connecting the outer side of the vortex-forming cylinder (1310) and the inner wall defining the air passage (1103), and may have a structure that extends continuously along the spiral.

[0082] A spiral passage can be formed by a vortex-forming cylinder (1310) and a vortex-forming spiral guide (1320). The spiral passage may be sealed except for an inlet and an outlet. Air from the cartridge internal space (1202) can reach the mouthpiece (150) after passing through the spiral passage. The spiral passage can induce vortex behavior of the air.

[0083] In one embodiment, the pitch, which is the distance between adjacent spirals of the vortex-forming spiral guide (1320), can be set differently depending on the type of functional material. For example, when the functional material consists of a relatively light dry powder, the pitch of the vortex-forming spiral guide (1320) can be set relatively large. In this case, the functional materials can be uniformly mixed even if a relatively small vortex behavior is induced, and the functional material can be smoothly transferred even without applying a large suction pressure. For example, when the functional material consists of a relatively heavy dry powder, the pitch of the vortex-forming spiral guide (1320) can be set relatively small. In this case, a relatively large vortex behavior is induced, and the functional materials can be uniformly mixed.

[0084] Referring to FIG. 6, the flow of air that flows into the suction device (10) according to one embodiment and is delivered to the user will be described.

[0085] When a user bites the mouthpiece (150) and inhales air, negative pressure may be generated inside the inhaler (10) due to the user's inhalation pressure. Due to the negative pressure, air from the outside may be drawn into the air inlet (1104), and a first air flow (P1) may be formed. The first air flow (P1) may advance in a first direction (e.g., the -Z direction in FIG. 6).

[0086] The first air flow (P1) can be converted into a second air flow (P2) by a bent portion formed on an air inlet passage extending from the air inlet (1104) to the air outlet (1105). The second air flow (P2) can advance in a second direction (e.g., the + / -X direction in FIG. 6).

[0087] The second airflow (P2) exiting the air outlet (1105) can be converted into a third airflow (P3) by the air guide plate (140). The third airflow (P3) can advance in a third direction (e.g., the obliquely inclined direction in FIG. 6).

[0088] The third airflow (P3) can move along with the functional material while passing through the internal space (1202) of the cartridge. The third airflow (P3) can switch to the fourth airflow (P4) after striking the cartridge base (1206). The fourth airflow (P4) can advance in the fourth direction (e.g., the +Z direction in FIG. 6).

[0089] The fourth airflow (P4) can be converted into a fifth airflow (P5) after passing through the vortex-forming structure (130). The fifth airflow (P5) still advances in the fourth direction but may have vortex behavior. The vortex behavior of the fifth airflow (P5) allows the functional material to be uniformly mixed.

[0090] The fifth airflow (P5) can pass a uniformly mixed functional material through the mouthpiece (150) and transfer it to the user's oral cavity or lungs.

[0091] FIGS. 7a and 7b show the internal structure of the housing (210) of the inhaler (20) according to one embodiment.

[0092] The suction device (20) shown in FIGS. 7a and 7b has similar components to the suction device (10) described with reference to FIGS. 1 to 6, except for the vortex-forming structure (230), so for the sake of simplification, a detailed description of identical or similar components is omitted.

[0093] Referring to FIGS. 7a and 7b, an inhaler (20) according to one embodiment may include a housing (210), a cartridge, a vortex-forming structure (230), an air guide plate (240), and a mouthpiece (250).

[0094] In one embodiment, the housing (210) may include a first housing (2110) and a second housing (2120), and the air guide plate (240) may include a first air guide plate (2410) and a second air guide plate (2420).

[0095] In one embodiment, the vortex-forming structure (230) may include a vortex-forming cylinder (2310), a vortex-forming spiral guide (2320), an additional vortex-forming spiral guide (2330), and a cavity (2340).

[0096] A vortex-forming cylinder (2310) may be positioned in the center of the air passage (2103). A vortex-forming spiral guide (2320) may be positioned between the vortex-forming cylinder (2310) and the inner wall defining the air passage (2103).

[0097] The vortex-forming cylinder (2310) may include a cylindrical body and hemispherical upper and lower portions coupled to the body. The diameter of the body of the vortex-forming cylinder (2310) may be smaller than the inner diameter of the air passage (2103). By having the upper and lower portions of the vortex-forming cylinder (2310) have a hemispherical shape, the resistance of the vortex-forming cylinder (1310) to the air flowing into the air passage (2103) can be minimized.

[0098] The vortex-forming spiral guide (2320) is a plate connecting the outer side of the vortex-forming cylinder (2310) and the inner wall defining the air passage (2103), and may have a structure that extends continuously along the spiral.

[0099] A spiral passage can be formed by a vortex-forming cylinder (2310) and a vortex-forming spiral guide (2320). The spiral passage may be sealed except for an inlet and an outlet. Air from the internal space of the cartridge may reach the mouthpiece (250) after passing through the spiral passage. The spiral passage can induce vortex behavior of the air.

[0100] An additional vortex-forming spiral guide (2330) may be located downstream of the vortex-forming cylinder (2310) and the vortex-forming spiral guide (2320) (e.g., on the +Z direction side in FIG. 7b). The additional vortex-forming spiral guide (2330) may extend from the vortex-forming spiral guide (2320). The additional vortex-forming spiral guide (2330) may have a plate structure that extends continuously along the spiral. A cavity (2340) may be located in the center of the air passage (2103) surrounded by the additional vortex-forming spiral guide (2330). One side of the additional vortex-forming spiral guide (2330) may be open to communicate with the cavity (2340).

[0101] As the airflow passes through the spiral passage formed by the vortex-forming cylinder (2310) and the vortex-forming spiral guide (2320), a portion of the airflow may pass through the additional vortex-forming spiral guide (2330). The portion of the airflow passing through the additional vortex-forming spiral guide (2330) may maintain almost the same flow velocity as when passing through the vortex-forming spiral guide (2320). Meanwhile, the remainder of the airflow may have its flow velocity reduced as it passes through the cavity (2340). The vortex behavior may be further enhanced by airflows having different flow velocities.

[0102] In one embodiment, the suction device (20) may not include a vortex-forming cylinder (2310). In this case, the vortex-forming structure (230) may have a structure in which a cavity (2340) is formed in the middle of a structure composed of a vortex-forming spiral guide (2320) and an additional vortex-forming spiral guide (2330), and the vortex-forming spiral guide (2320) and the additional vortex-forming spiral guide (2330) may be configured to communicate with each other through the cavity (2340).

[0103] In one embodiment, the vortex-forming structure may be implemented as a rotating blade-shaped structure or a structure with a bearing mounted at the center that rotates by suction pressure.

[0104] FIG. 8a shows an inhaler (30) according to one embodiment, FIG. 8b shows the internal structure of the inhaler (30) with the cartridge (320) detached, and FIG. 8c and FIG. 8d show the cartridge (320) of the inhaler (30) according to one embodiment.

[0105] The inhaler (30) of FIGS. 8a to 8d has the same or similar components as the inhaler (10) described with reference to FIGS. 1 to 6, so for the sake of simplification, a detailed description of the same or similar components is omitted.

[0106] Referring to FIGS. 8a through 8d, an inhaler (30) according to one embodiment may include a housing (310), a cartridge (320), a vortex-forming structure (330), and a mouthpiece (350). The inhaler (30) does not include an air guide plate.

[0107] In one embodiment, the housing (310) may include a first housing (3110) and a second housing (3120). The housing (310) may include an opening (3101), a cartridge receiving space (3102), an air passage (3103), an air inlet (3104), and an air outlet (3105).

[0108] In one embodiment, the cartridge (320) may include a cartridge first body (3210), a cartridge second body (3220), a cartridge internal space (3202), and a cartridge base (3206).

[0109] The first cartridge body (3210) and the second cartridge body (3220) may be formed to a size that can be accommodated in the cartridge receiving space (3102) of the second housing (3120). For example, the first cartridge body (3210) and the second cartridge body (3220) may be configured with a shape corresponding to the cartridge receiving space (3102) and may be coupled to the cartridge receiving space (3102) in an interference fit manner.

[0110] The cartridge (320) may further include a cartridge air inlet (3204) and a cartridge air outlet (3205).

[0111] With the cartridge (320) coupled to the housing (310), the cartridge air inlet (3204) may be formed in a position facing the air outlet (3105). For example, the cartridge air inlet (3204) may be formed on the outer side of the cartridge first body (3210) and positioned to face the air outlet (3105), so that air coming out of the air outlet (3105) can easily flow into the cartridge air inlet (3204).

[0112] The cartridge air outlet (3205) may be formed to communicate with the cartridge air inlet (3204) and to face the cartridge internal space (3202).

[0113] The cartridge base (3206) may form part of the cartridge internal space (3202). In particular, with reference to FIG. 8d, the cartridge base (3206) may have an inverted triangular cross-sectional shape. The cartridge air outlet (3205) may be positioned to meet the vertex of the cartridge base (3206).

[0114] Since the cartridge base (3206) has an inverted triangular structure, the functional material contained in the cartridge internal space (3202) can be gathered at the central lower part of the cartridge internal space (3202). Air introduced into the housing (310) can be introduced into the cartridge air outlet (3205). The functional material gathered at the apex of the cartridge base (3206) can be easily transferred by the air, and no residue of the functional material can remain in the cartridge internal space (3202).

[0115] In one embodiment, the suction device (30) does not include an air guide plate, so the manufacturing of the suction device (30) is simplified and the possibility of breakage is reduced, thereby increasing durability.

[0116] FIG. 9 shows the operating state of the suction device (40) according to one embodiment.

[0117] Since the inhaler (40) of FIG. 9 has the same or similar components as the inhaler (10) described with reference to FIG. 1 to 6, a detailed description of the same or similar components is omitted for the sake of simplification.

[0118] Referring to FIG. 9, an inhaler (40) according to one embodiment may include a housing (410), a cartridge, a vortex-forming structure (430), an air guide plate (440), and a mouthpiece (450).

[0119] The air guide plate (440) may include a first air guide plate (4410) and a second air guide plate (4420).

[0120] The first air guide plate (4410) and / or the second air guide plate (4420) may be configured to be rotatable. The first air guide plate (4410) and / or the second air guide plate (4420) may be rotatable between a closed state in which the end of the first air guide plate (4410) and the end of the second air guide plate (4420) are in contact with each other and an open state in which the respective ends are separated.

[0121] When the suction device (40) is not in use, the first air guide plate (4410) and the second air guide plate (4420) can be rotated to a closed state. When the suction device (40) is in use, the first air guide plate (4410) and the second air guide plate (4420) can be rotated to an open state.

[0122] For example, the first air guide plate (4410) or the second air guide plate (4420) may be rotatably hinged to the inner wall of the housing (410). The first air guide plate (4410) or the second air guide plate (4420) may be kept in a closed state by an elastic element (e.g., a torsion spring) and may be switched to an open state when a cartridge is coupled.

[0123] Even when the cartridge is separated from the housing (410) when the inhaler (40) is not in use, the first air guide plate (4410) and the second air guide plate (4420) remain in a closed state, so the functional material remaining inside the housing (410) does not leak out of the housing (410), and thus the cleanliness of the inhaler (40) can be maintained.

[0124] According to the suction device (10, 20, 30, 40) according to one embodiment, the functional substance can be discharged smoothly and uniformly, and the vortex behavior of the air carrying the functional substance can be smoothly induced. According to the suction device (10, 20, 30, 40) according to one embodiment, it can be used multiple times, and leakage of the functional substance can be effectively prevented even during multiple uses. According to the suction device (10, 20, 30, 40) according to one embodiment, appropriate suction resistance can be achieved, and aesthetic appeal can be enhanced.
