Description

Cartridges and inhalers containing them

[0001] Various embodiments of the present disclosure relate to cartridges and inhalers including the same, and more particularly, to cartridges having an improved internal structure and inhalers including the same.

[0002] Research has been conducted on inhalers that deliver target substances directly to the user's lungs. These target substances may include theanine, caffeine, taurine, nicotine, etc., and may be in the form of fine granules or dry powders.

[0003] The target substance can be stored in a cartridge. In this case, the cartridge can be inserted into the inhaler and used. When the target substance is exhausted, the inhaler can be refilled with the target substance or the cartridge can be replaced to continue using the inhaler.

[0004] Areas where inhalers are applied include electronic cigarettes that store tobacco substances, and drug inhalation devices that aerosolize medicinal substances to treat diseases such as asthma or lung diseases.

[0005] When a user places the inhaler's mouthpiece in their mouth and inhales the target substance, the target substance travels through the cartridge and the inhaler along with the air, potentially reaching the user's oral cavity. The cartridge and inhaler must be designed to effectively transport the target substance through the air.

[0006] Additionally, when designing an inhaler, holes must be placed to allow air to enter the cartridge. However, there is a possibility that the target substance may leak out of the inhaler through these holes. Therefore, the cartridge and inhaler must be designed to minimize this phenomenon.

[0007] Meanwhile, the target substance stored within the cartridge may exist in a clumped, aggregated form. From the user's perspective, smaller particles are more easily inhaled, making it easier to inhale. Therefore, a structure capable of deagglomerating these particles within the inhaler before the user inhales the target substance is necessary.

[0008] Embodiments provide a cartridge having an inclined internal structure and an inhaler including the same.

[0009] Embodiments also provide a cartridge and an inhaler including the same, wherein the air intake portion is designed to be bent at least once.

[0010] Additionally, embodiments provide a cartridge having a cyclone structure and an inhaler including the same.

[0011] The problems to be solved through the embodiments are not limited to the problems described above, and problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the embodiments belong from this specification and the attached drawings.

[0012] In one embodiment, a cartridge may include a housing forming an exterior of the cartridge, a receiving portion formed in the housing for receiving a target material, a passage portion formed in the housing for fluidly connecting the exterior of the housing and the receiving portion, and an opening formed in the housing for allowing the target material received in the receiving portion to pass through, and the receiving portion may include a first surface extending in a first direction and a second surface inclined with respect to the first direction, one end of the second surface may be connected to the passage portion, and the other end of the second surface may be connected to the opening.

[0013] An inhaler according to one embodiment may include a cartridge including a housing, a receiving portion formed in the housing for receiving a target substance, a passage portion formed in the housing for fluidly connecting the outside of the housing and the receiving portion, and an opening formed in the housing for allowing the target substance received in the receiving portion to pass through, and a body to which the cartridge is detachably coupled, the body including a receiving space for receiving the cartridge, a mouthpiece protruding to the outside of the body and contacting a user's mouth, and a passage connecting the opening of the cartridge and the mouthpiece, the receiving portion may include a first surface extending in a first direction and a second surface inclined with respect to the first direction, one end of the second surface may be connected to the passage portion, and the other end of the second surface may be connected to the opening.

[0014] According to the cartridge and the inhaler including the same according to the embodiments, a target substance can be effectively supplied to a user.

[0015] Additionally, according to the cartridge and the inhaler including the same according to the embodiments, leakage of the target substance through a part other than the mouthpiece can be prevented.

[0016] In addition, according to the cartridge and the inhaler including the same according to the embodiments, particles larger than a certain size can be prevented from entering the user and the sensation of inhalation of the target substance can be improved.

[0046] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0047] Figure 1 is a perspective view showing the main body of an inhaler and a cartridge separated therefrom according to one embodiment.

[0048] Referring to FIG. 1, an inhaler (1) according to one embodiment may include a main body (100) and a cartridge (200).

[0049] The main body (100) may occupy most of the exterior of the inhaler (1). The cartridge (200) may be detachably coupled to a portion of the main body (100) to form a portion of the exterior of the inhaler (1) together with the main body (100).

[0050] The embodiment is not limited to an example in which the cartridge (200) is detachably coupled to the main body (100), and the cartridge (200) may be formed integrally with the main body (100). However, the following description will focus on an embodiment in which the cartridge (200) is detachably coupled to the main body (100), and each of the main body (100) and the cartridge (200) is treated as a component of the inhaler (1). In this case, the remaining components excluding the cartridge (200) may be referred to as the main body (100).

[0051] Referring to FIG. 1, the main body (100) may include a body (110) and a mouthpiece (120).

[0052] The body (110) forms the exterior of the inhaler (1) and can perform the function of accommodating and protecting components of the inhaler (1). For example, the body (110) can accommodate a cartridge (200).

[0053] As shown, the body (110) may include a rectangular parallelepiped shape, but is not limited thereto and may be manufactured in various shapes such as a cylinder, an elliptical column, or a polygonal column, and the embodiment is not limited to the shape of the body (110) shown in FIG. 1.

[0054] The body (110) may include a receiving space (not shown) for receiving a cartridge (200) therein. The receiving space (110i) may be formed at the lower portion of the body (110). The receiving space may be opened downward to allow access to the cartridge (200). At least a portion of the cartridge (200) may be received within the body (110) through the opening at the lower portion of the receiving space. The receiving space may have a shape corresponding to the shape of the cartridge (200). For example, the receiving space may have a rectangular parallelepiped shape.

[0055] The mouthpiece (120) is a configuration that serves as a passage for the target substance stored inside the inhaler (1) to move to the outside of the inhaler (1). The mouthpiece (120) is placed on the upper portion of the body (110) and can come into contact with the user's mouth. The mouthpiece (120) may be formed to protrude from the body (110) in the +z direction. The mouthpiece (120) may have a shape that can easily come into contact with the user's mouth. The user can inhale the target substance after bringing the mouth into contact with the mouth of the mouthpiece (120) formed on the body (110).

[0056] The cartridge (200) can accommodate a target substance. The target substance may include one or more of various forms, such as dry powder, fine granules, etc. When the target substance is in the form of a dry powder, the cartridge (200) can store powder of about 30 mg, 50 mg, 100 mg, or 300 mg, 600 mg, 1000 mg, etc.

[0057] When the target substance is in the form of a dry powder, the target substance may be composed solely of an inhalable powder having a size of about 1 μm to 5 μm or about 0.5 μm to 10 μm. Alternatively, the target substance may be composed in the form of a mixture of an inhalable powder having a size of about 1 μm to 5 μm or about 0.5 μm to 10 μm and a carrier having a size of about 10 μm to 20 μm or about 5 μm to 50 μm.

[0058] Powders that can be used as inhalable substances may include, for example, nicotine salts such as nicotine, nicotine tartrate, nicotine lactate, and nicotine citrate, as well as other functional substances such as caffeine. Furthermore, the powder may contain substances that can produce other pharmacological effects.

[0059] Powders that can be applied as carrier materials may be powders containing, for example, lactose, menthol, peppermint, or powders containing other essential oils.

[0060] Materials that can be used as carriers include, for example, alpha-lactose monohydrate, beta cyclodextrin, maltodextrin, and mannitol, and may be in the form of an appropriate mixture of the above excipients. In addition, the above excipients and small amounts of other excipients such as saccharin and xylitol may be included.

[0061] The cartridge (200) can be detachably coupled to the body (110) of the main body (100) while containing a target material therein. For example, the cartridge (200) can be mounted on the main body (100) by inserting at least a portion of the cartridge (200) into the main body (100) or by inserting at least a portion of the main body (100) into the cartridge (200).

[0062] The main body (100) and the cartridge (200) can be maintained in a combined state by a snap-fit ​​method, a screw-joint method, a magnetic coupling method, a forced fit method, etc. However, the method of combining the main body (100) and the cartridge (200) is not limited to the above-described method.

[0063] The cartridge (200) can be used as a consumable in the inhaler (1). When the target substance contained in the cartridge (200) is exhausted while using the inhaler (1), the user can separate the cartridge (200) from the main body (100) and use a new cartridge (200) by combining it with the main body (100).

[0064] However, the embodiment is not limited to an example in which the cartridge (200) is used as a consumable. According to the embodiment, the cartridge (200) may be used in a refilling manner of the target material, such as by filling a new target material into the same cartridge (200).

[0065] Meanwhile, although not shown, the inhaler (1) according to one embodiment may further include a cap (not shown) that can be mounted on the mouthpiece (120). The user can mount the cap on the mouthpiece (120) when not using the inhaler (1).

[0066] The cap can prevent the target substance inside the inhaler (1) from leaking out through the mouthpiece (120). In addition, the cap can prevent foreign substances from entering the inside of the inhaler (1) through the mouthpiece (120).

[0067] Below, the internal structure of the inhaler (1) and the movement path of the target substance will be described in detail.

[0068] Fig. 2a is a perspective view of a cartridge according to one embodiment. Fig. 2b is a cross-sectional view of the cartridge of Fig. 2a taken along cross-sectional line A-A'.

[0069] Referring to FIGS. 2A and 2B, a cartridge (200) according to one embodiment may include a housing (210), a receiving portion (220), a passage portion (230), an opening portion (240), and a groove portion (250).

[0070] The housing (210) is a component that forms the exterior of the cartridge (200). At this time, the receiving portion (220), passage portion (230), opening portion (240), and groove portion (250) of the cartridge (200) may be components formed in the housing (210). That is, the listed components may be components included in the cartridge (200) and also components included in the housing (210). The components of the cartridge (200) may be determined depending on the shape of the housing (210).

[0071] The receiving portion (220) is a configuration formed in the housing (210) to receive a target material. At this time, the receiving portion (220) may correspond to a groove formed in a portion of the housing (210). The target material may be stored in the receiving portion (220).

[0072] The receiving portion (220) may include a first surface (221) extending in a first direction (e.g., the z-axis direction) and a second surface (222) inclined with respect to the first direction. The target material may be positioned between the first surface (221) and the second surface (222).

[0073] One end of the second surface (222) may be connected to a passageway (230) to be described later, and the other end of the second surface (222) may be connected to an opening (240) to be described later. Air introduced into the receiving portion (220) may move along the second surface (222) and transport the target material from the passageway (230) toward the opening (240). At this time, since the second surface (222) has an inclined structure, a small amount of the target material remaining inside the receiving portion (220) may also move along the inclined surface together with the air.

[0074] The passageway (230) is a configuration that fluidly connects the exterior of the housing (210) and the receiving portion (220). In this case, "fluid connection" may mean that elements are connected so that a fluid, such as air, can pass through and flow. Hereinafter, the expression "connection" may include the meaning of fluid connection.

[0075] The passageway (230) may correspond to a passageway formed in a portion of the housing (210). The passageway (230) may serve as a passageway through which air flows into the interior of the inhaler when the user uses the inhaler. In other words, the passageway (230) may correspond to a configuration through which air first passes when air flows into the interior of the inhaler or cartridge (200). At this time, the size of the passageway (230) may be sufficiently small so as to provide sufficient suction resistance to the user of the inhaler (1).

[0076] Meanwhile, the target material stored in the receiving portion (220) may leak out of the housing (210) or the cartridge (200) through the passage portion (230). To solve this problem, the passage portion (230) may include a curved shape at least once.

[0077] Hereinafter, the shape of the passage (230) will be described in detail. The passage (230) may include an air inlet (230i), a first passage (231), a second passage (232), a third passage (233), and an air inlet (230e).

[0078] The air inlet (230i) is configured to be open toward the outside of the housing (210) and connected to the outside of the housing (210). The air inlet (230i) can serve as an entrance to the passageway (230).

[0079] The air inlet (230i) can be opened toward the lower part (e.g., in the z-axis direction) of the cartridge (200). Since the cartridge (200) approaches and is coupled to the inhaler body (e.g., the body (100) of FIG. 1) in the z-axis direction, even if there is no separate opening in the body, the air inlet (230i) can serve as an inlet of the inhaler.

[0080] However, depending on the embodiment, the direction in which the air inlet (230i) opens may vary, and accordingly, an opening connected to the air inlet (230i) of the cartridge (200) may be arranged in the main body. In addition, even when the cartridge (200) approaches and connects to the main body from a different direction, the air inlet (230i) and the opening of the main body connected thereto may be arranged in an appropriate position.

[0081] The first passage (231) is a passage extending in a first direction (e.g., z-axis direction) from the air inlet (230i). Referring to the drawing, the air inlet (230i) is open in the first direction, and the first passage (231) extends in the direction in which the air inlet (230i) is opened, but the embodiment is not limited to what is shown. The direction in which the air inlet (230i) is opened and the direction in which the first passage (231) extends may vary depending on the embodiment.

[0082] The second passage (232) is a passage that is connected to the first passage (231) and extends in a second direction (e.g., x-axis direction) that crosses the first direction. At this time, the second passage (232) can connect the first passage (231) and the third passage (233). Referring to the drawing, the second passage (232) is formed shorter than the first passage (231) or the third passage (233), but the embodiment is not limited to what is shown. The ratio of the length of the first passage (231) or the third passage (233) to the length of the second passage (232) may vary depending on the embodiment.

[0083] The third passage (233) is connected to the second passage (232) and is a passage extending in the first direction. That is, the third passage (233) may extend in the same direction as the first passage (231). However, the embodiment is not limited to the same direction. The direction in which the first passage (231) and the third passage (233) extend may vary depending on the embodiment.

[0084] The air inlet (230e) is configured to be open toward the receiving portion (220) and connected to the receiving portion (220). The air inlet (230e) is connected to the third passage (233) and can serve as an outlet of the passage (230). The air inlet (230e) can be formed on the first surface (221) of the receiving portion (220).

[0085] Referring to the drawing, the air inlet (230e) is open in the second direction, and the third passage (233) extends in a direction crossing the direction in which the air inlet (230e) is opened, but the embodiment is not limited to what is shown. The direction in which the air inlet (230i) is opened and the direction in which the first passage (231) extends may vary depending on the embodiment, and the two directions may be the same.

[0086] In summary, air can reach the receiving portion (220) from the outside of the housing (210) through the air inlet (230i), the first passage (231), the second passage (232), the third passage (233), and the air inlet (230e).

[0087] Since the target material is located between the first surface (221) and the second surface (222) of the receiving portion (220), the target material can be accumulated in the receiving portion (220) in a first direction (e.g., z-axis direction). At this time, the receiving portion (220) and the passage portion (230) can be arranged in parallel along a second direction (e.g., x-axis direction) that is a direction crossing the first surface (221) of the receiving portion (220). The air inlet (230e) connected to the receiving portion (220) can be opened in a second direction crossing the first direction.

[0088] Accordingly, when the cartridge (200) is positioned so that the first direction is the direction of gravity, the target material stored in the receiving portion (220) can be prevented from flowing out through the air inlet (230e).

[0089] Also, as shown, the part where the air inlet (230e) and the third passage (233) are connected, the part where the third passage (233) and the second passage (232) are connected, and the part where the second passage (232) and the first passage (231) are connected are bent. That is, the directions in which the air inlet (230e) and the third passage (233) are opened are different from each other, the directions in which the third passage (233) and the second passage (232) are opened are different from each other, and the directions in which the second passage (232) and the first passage (231) are opened are different from each other.

[0090] Accordingly, even if the target material stored in the receiving portion (220) flows back into the passage portion (230), the phenomenon of the target material flowing out of the housing (210) along the passage portion (230) can be prevented due to the curved shape of the passage portion (230).

[0091] Additionally, the first passage (231) and the third passage (233) may be arranged in parallel along the second direction. Specifically, when the air flowing into the cartridge (200) moves along the first passage (231), it may move in the +z direction, and when it moves along the third passage (233), it may move in the -z direction.

[0092] Conversely, the target material flowing back from the receiving portion (220) must move in the +z direction when moving along the third passage (233) and in the -z direction when moving along the first passage (231) to be able to flow out of the housing (210).

[0093] Accordingly, since the target material must move in multiple directions to flow out of the housing (210) or cartridge (200) through the passage (230), the phenomenon of the target material flowing out of the housing (210) along the passage (230) can be prevented.

[0094] Meanwhile, the cross-sectional area of ​​the first passage (231) cut in the second direction may increase as it moves away from the air inlet (230i). By adopting this structure, air can be drawn into the relatively narrow air inlet (230i) and spread out to an increasingly wider area as it moves along the first passage (231).

[0095] If the cartridge (200) is designed to have a consistently wide width from the air inlet (230i) to the end of the first passage (231), a large amount of the target substance may be inhaled by the user even if the user attempts to inhale only a small amount of the target substance. Furthermore, the suction resistance and the pressure applied to the passage (230) may be low, resulting in wasted suction. According to an embodiment, such phenomena can be prevented.

[0096] The opening (240) is a configuration formed in the housing (210) so that the target substance contained in the receiving portion (220) can pass through when moving with air. Specifically, air introduced into the receiving portion (220) through the passage (230) can carry the target substance. The air together with the target substance can pass through the opening (240) and move to the outside of the housing (210) or the cartridge (200). In other words, the opening (240) may correspond to a configuration through which air passes last from the inside of the cartridge (200). In addition, when the target substance is completely consumed, the user can refill the receiving portion (220) with the target substance through the opening (240).

[0097] Referring to the drawing, one end of the first surface (221) and one end of the second surface (222) may be connected to an air inlet (230e) of a passageway (230), and the other end of the first surface (221) and the other end of the second surface (222) may be connected to an opening (240).

[0098] Since the second surface (222) is an inclined surface inclined with respect to the first surface (221), one end of the first surface (221) and one end of the second surface (222) may be relatively close, and the other end of the first surface (221) and the other end of the second surface (222) may be relatively far apart.

[0099] As illustrated, the space between the other end of the first surface (221) and the other end of the second surface (222) may correspond to an opening (240). That is, the open area of ​​the opening (240) is relatively large compared to the open area of ​​the air inlet (230e). However, the embodiment is not limited to the embodiment illustrated. According to the embodiment, the upper part of the receiving portion (220) may be blocked by the housing (210), and a relatively small opening may be arranged in the housing (210).

[0100] Meanwhile, the opening (240) may be opened in a first direction, and the air inlet (230e) of the passage (230) may be opened in a second direction (e.g., x-axis direction) that crosses the first direction. When the cartridge (200) is mounted on the inhaler body, the opening (240) may face the inhaler body. At this time, since the air inlet (230e) is opened in a direction crossing the longitudinal direction of the inhaler body, rather than in a direction away from the inhaler body (e.g., -z direction), the user may prevent an unwanted target substance from leaking through the air inlet (230e) while using the inhaler.

[0101] The groove (250) is formed by recessing one edge of the outer side of the housing (210) and one surface of the housing (210) including the edge. Two grooves (250) may be arranged. For example, the grooves (250) may include a first groove (251) and a second groove (252) which are arranged to face each other. The first groove (251) may be arranged on one surface of the housing (210), and the second groove (252) may be arranged on the other surface of the housing (210) opposite the one surface.

[0102] When the cartridge (200) is mounted on the inhaler body, a problem may arise in which it is difficult to separate the cartridge (200) from the body when the cartridge (200) is fully inserted into the inhaler body. At this time, since the grooves (250) are arranged on the cartridge (200), the user can separate the cartridge (200) from the inhaler body by holding the first grooves (251) and the second grooves (252) with their hands.

[0103] Fig. 3a is a perspective view of an inhaler body according to one embodiment. Fig. 3b is a cross-sectional view of the inhaler body of Fig. 3a taken along the line B-B'.

[0104] Referring to FIGS. 3a and 3b, the inhaler body (100) according to one embodiment may include a body (110), a mouthpiece (120), and a urea (130).

[0105] At least one of the components of the inhaler (1) illustrated in FIGS. 3a and 3b may be identical or similar to at least one of the components of the inhaler (1) illustrated in FIG. 1, and any redundant description thereof will be omitted below.

[0106] The flow path (130) is a configuration that connects a cartridge (e.g., cartridge (200) of FIG. 1) and a mouthpiece (120). The flow path (130) can be fluidly connected to an opening of the cartridge (200) (e.g., opening (240) of FIG. 2A). A target substance stored in the cartridge (200) can pass through the opening and enter the flow path (130). Thereafter, the target substance can move along the flow path (130) and be inhaled by the user.

[0107] The main body (100) may further include a protrusion (140) for efficient transfer of the target substance. The protrusion (140) includes a hollow portion (140H) connected to the mouthpiece (120) and is configured to protrude inwardly from the body (110). While the mouthpiece (120) protrudes outwardly from a portion of the body (110), the protrusion (140) may protrude inwardly from a portion of the body (110). The mouthpiece (120) and the protrusion (140) may be aligned in a row. The target substance moving along the hollow portion (140H) of the protrusion (140) may reach the mouthpiece (120) and be inhaled by the user.

[0108] Hereinafter, the euro (130) will be described in detail. The euro (130) may include an inlet (131), a chamber (132), a connection (133), and an outlet (134).

[0109] The inlet (131) is configured to be open toward the receiving space (110i) of the body (110) and connected to the cartridge. The inlet (131) can serve as the inlet of the flow path (130).

[0110] The inlet (131) may be opened toward the lower portion (e.g., in the z-axis direction) of the body (110). When the cartridge approaches the inhaler body (e.g., the body (100) of FIG. 1) in the z-axis direction and is coupled to the receiving space (110i), the positions of the inlet (131) and the opening of the cartridge may be aligned. Accordingly, air passing through the cartridge (200) may be introduced into the inlet (131) through the opening.

[0111] As shown, the inlet (131) is open in a first direction (e.g., z-axis direction) together with the opening, but the direction in which the inlet (131) is opened may vary depending on the embodiment. In this case, the position of the opening of the cartridge may also vary depending on the position of the inlet (131). The positions of the inlet (131) and the opening may be determined so that air passing through the opening can be introduced into the inlet (131).

[0112] The chamber (132) is an empty space having a cylindrical shape. The chamber (132) is formed on the inside of the body (110), and the wall constituting the chamber (132) may correspond to a portion of the body (110). Air that passes through the inlet (131) and flows into the chamber (132) may rotate along the cylindrical chamber (132). The chamber (132) may be arranged at the bottom of the mouthpiece (120) and may be connected to the mouthpiece (120). The air that rotates along the chamber (132) may move to the mouthpiece (120).

[0113] When the protrusion (140) is arranged, the chamber (132) can accommodate the protrusion (140). The air inside the chamber (132) can move to the lower part of the chamber (132) while rotating and be introduced into the hollow space (140H) of the protrusion (140). The air introduced into the hollow space (140H) can be introduced into the mouthpiece (120).

[0114] A structure designed to cause air to rotate and move downward along the walls of a chamber (132) can be referred to as a cyclone structure. By utilizing a cyclone structure, sufficient vortices can be generated within the chamber (132), and when a strong flow velocity is added to the vortices, target materials that have clumped together can be deagglomerated.

[0115] Additionally, relatively large particles or foreign substances can be removed from the lower portion of the chamber (132), and only relatively small particles can be introduced into the hollow space (140H) via the air. Accordingly, particles larger than a certain size can be prevented from entering the user's mouth, thereby improving the inhalation sensation of the target substance.

[0116] The connecting portion (133) is a passage connecting the inlet portion (131) and the chamber (132). In order to connect the inlet portion (131) extending in the first direction and the chamber (132) arranged in the center of the body (110), the connecting portion (133) may extend in a second direction (e.g., x-axis direction) that crosses the first direction.

[0117] The connecting portion (133) can be connected to the chamber (132) by extending from the end of the inlet portion (131) in a tangential direction to the cylindrical chamber (132). When air flows into the chamber (132) along the connecting portion (133), the air can smoothly rotate along the wall surface of the chamber (132) because it flows in a tangential direction to the cylindrical shape.

[0118] The discharge portion (134) is a passage extending from the chamber (132) to the mouthpiece (120). When the protrusion (140) is arranged, the discharge portion (134) can extend to the mouthpiece (120) along the hollow portion (140H) of the protrusion (140). Air passing through the cyclone structure can pass through the discharge portion (134) together with the target material and be inhaled by the user.

[0119] In summary, air can pass through the cartridge (200) and pass through the inlet (131), connection (133), chamber (132), and outlet (134) to reach the user's mouth.

[0120] Meanwhile, the cross-sectional area of ​​the cross-section of the inlet portion (131) cut in a direction transverse to the direction in which the inlet portion (131) extends may become smaller as it approaches the connecting portion (133). Referring to the drawing, one end of the inlet portion (131) facing the receiving space (110i) is formed wide, while the other end of the inlet portion (131) is formed narrow.

[0121] The connecting portion (133) connected to the other end of the inlet portion (131) may also extend in the second direction while maintaining a narrow width. The narrower the width of the connecting portion (133), the more air can be introduced into the chamber (132) in a direction closer to the tangential direction of the cylindrical shape. As a result, the air can smoothly rotate along the wall surface of the chamber (132).

[0122] Meanwhile, although not shown, the inhaler body (100) may include a mesh net (not shown) arranged within a certain area of ​​the mouthpiece (120). The presence of the mesh net may provide suction resistance to the user of the inhaler. Furthermore, due to the arrangement of the mesh net, the powder for inhalation and the carrier material may collide with the mesh net, separate from each other, and then be inhaled by the user.

[0123] Figure 4 is a side view of an inhaler according to one embodiment in which the inhaler body and the cartridge are combined.

[0124] Referring to Fig. 4, an inhaler (1) according to one embodiment may include a main body (100) and a cartridge (200). At least one of the components of the inhaler (1) illustrated in Fig. 4 may be identical or similar to at least one of the components of the inhaler (1) described above, and any redundant description will be omitted below.

[0125] When a user of the inhaler (1) puts the mouthpiece (120) in his / her mouth and inhales air or a target substance, air can be introduced into the interior of the inhaler (1) through the air inlet (230i) of the cartridge (200).

[0126] Air can sequentially pass through the first passage (231), the second passage (232), and the third passage (233) of the passage unit (230) and be introduced into the receiving unit (220) through the air inlet (230e). The air can transport the target material stored in the receiving unit (220). The air can move along the inclined surface of the receiving unit (220) together with the target material and move to the outside of the cartridge (200) through the opening (240).

[0127] Since the opening (240) is connected to the inlet (131) of the flow path (130), when air passes through the opening (240), it can be introduced into the inlet (131) of the main body (100). The air introduced into the interior of the body (110) can sequentially pass through the inlet (131), connection (133), chamber (132), and outlet (134) of the flow path (130) and be introduced into the user's mouth through the mouthpiece (120).

[0128] At this time, the air passing through the chamber (132) can rotate along the wall surface of the chamber (132). The air rotating in the area adjacent to the discharge portion (134) can be introduced into the discharge portion (134). When the protrusion (140) is arranged, the air passing through the chamber (132) does not simply cross the chamber (132) and enter the hollow space formed in the protrusion (140), but can rotate along the wall surface of the chamber (132) and simultaneously move to the lower part of the chamber (132) and be introduced into the hollow space of the protrusion (140).

[0129] Below, with reference to FIG. 5, another example in which a cyclone structure is implemented inside the chamber (132) will be described.

[0130] FIG. 5 is a perspective view showing another example of a chamber that can be applied to the inhaler of FIG. 4.

[0131] Referring to Fig. 5, only a portion of the inhaler body (100) is illustrated. At least one of the components of the body (100) illustrated in Fig. 5 may be identical or similar to at least one of the components of the body (100) described above, and any redundant description will be omitted below.

[0132] In another embodiment, the body (100) of the inhaler may further include a guide portion (150). The guide portion (150) is configured to be coupled to the outer surface of the protrusion portion (140). The guide portion (150) may guide the movement of air so that the air can smoothly rotate inside the chamber (132).

[0133] When air is introduced into the chamber (132), since the guide portion (150) is arranged at the center of the chamber (132), the air can only move through the periphery of the chamber (132). That is, the air can move along the wall surface at a position adjacent to the wall surface forming the chamber (132). Accordingly, the air can move while rotating inside the chamber (132).

[0134] In addition, the guide portion (150) may include a plurality of blades (151) that guide the movement of air. Referring to the drawing, the plurality of blades (151) may be arranged to wrap around the guide portion (150) in a clockwise direction when the mouthpiece (120) or the protrusion (140) is used as a rotation axis. Accordingly, the plurality of blades (151) of the guide portion (150) may guide the movement of air so that the air rotates clockwise inside the chamber (132).

[0135] However, since the direction in which the air rotates is determined by the position of the connection part (133) to the chamber (132), the direction in which the wing (151) wraps around the guide part (150) may vary depending on the embodiment.

[0136] Meanwhile, in the main body (100) of the inhaler according to another embodiment, the chamber (132) may be divided into two regions. Specifically, the chamber (132) may include a first region (132A) in the shape of a cylinder in which the guide portion (150) is arranged, and a second region (132B) in which the end of the protrusion portion (140) is arranged.

[0137] The first region (132A) is positioned above the second region (132B), and air introduced into the chamber (132) can sequentially pass through the first region (132A) and the second region (132B) and then be introduced into the hollow space (140H) of the protrusion (140). At this time, the first region (132A) may have a cylindrical shape, while the second region (132B) may have a funnel shape. In other words, the second region (132B) may become narrower as it moves away from the first region (132A).

[0138] According to this configuration, as air rotates in the second region (132B) and moves downward, it can gather in the center of the second region (132B). The air gathered in the center can smoothly move into the hollow space (140H) of the protrusion (140), and particles falling to the bottom surface of the second region (132B) can also gather in a relatively narrow space.

[0139] Although not shown, the bottom surface of the chamber (132) or the bottom surface of the second region (132B) can be opened and closed according to the user's operation. When at least one region of the bottom surface is opened, particles that fall to the bottom surface of the chamber (132) can be discharged through the open region into a receiving space (e.g., receiving space (110i) of FIG. 3A).

[0140] When a cartridge is mounted in the receiving space, particles passing through the open area of ​​the bottom surface of the chamber (132) can pass through the opening of the cartridge and enter the receiving portion. According to this structure, particles entering the receiving portion can be moved back to the chamber (132) by the user's inhalation, deagglomerated by the cyclone structure, and then inhaled by the user or settled back to the bottom surface of the chamber (132). By repeating this process, the target substance filled in the cartridge can be inhaled to the user to the maximum extent.

[0141] Figure 6 is a cross-sectional view of a cartridge according to another embodiment with a door applied.

[0142] Referring to FIG. 6, a cartridge (200) according to another embodiment may further include a door (260) compared to the cartridge (200) of FIG. 2b.

[0143] At least one of the components of the cartridge (200) illustrated in FIG. 6 may be identical or similar to at least one of the components of the cartridge (200) described above, and any redundant description thereof will be omitted below.

[0144] Despite the curved shape of the passage (230), there is a possibility that the target material may move along the passage (230) and leak out of the housing (210). Additionally, external foreign substances may enter the interior of the cartridge (200) through the passage (230). To prevent this phenomenon, a door (260) may be placed to block the passage (230) when the user is not using the inhaler.

[0145] The door (260) is configured to slide to open and close the air inlet (230i) of the passageway (230). The door (260) can move between the open position and the closed position of the air inlet (230i).

[0146] At least a portion of the door (260) may be accommodated in a sliding groove (215) formed in the housing (210). The sliding groove (215) may be positioned adjacent to the air inlet (230i) and may be connected to the air inlet (230i). In this case, the sliding groove (215) may be formed in the housing (210) so as to cross the first passage (231).

[0147] The door (260) can slide within the sliding groove (215). That is, the sliding groove (215) can guide the sliding movement of the door (260). Accordingly, the door (260) can slide only in the direction in which the sliding groove (215) extends (e.g., in the x-axis direction).

[0148] Referring to the drawing, the door (260) is in a position to close the air inlet (230i). At this time, when the door (260) moves along the sliding groove (215), the air inlet (230i) can be opened. The door (260) in the open position is shown by a dotted line in the enlarged view.

[0149] Meanwhile, although not shown in the drawing, a fastening structure, such as a hook, may be placed at one end of the door (260) to prevent the door (260) from moving in the closed position. Correspondingly, a hole into which the hook is inserted may be placed in the sliding groove (215). Accordingly, the door (260) may be fixed in the closed position.

[0150] Additionally, to enable the user to move the door (260) accommodated in the sliding home (215), a handle (not shown) protruding from the outside of the housing (210) may be placed on the door (260).

[0151] Figures 7a to 7c are cross-sectional views of cartridges according to further embodiments.

[0152] Referring to FIGS. 7a to 7c, cartridges (200a, 200b, 200c) of various shapes are respectively illustrated.

[0153] At least one of the components of the cartridges (200a, 200b, 200c) illustrated in FIGS. 7a to 7c may be identical or similar to at least one of the components of the cartridge (200) illustrated in FIG. 2b, and any redundant description thereof will be omitted below. In addition, when describing FIGS. 7a to 7c, reference will be made to the drawing symbols of FIG. 4.

[0154] Referring to FIG. 7a, the cartridge (200a) illustrated in FIG. 7a may further include an upper wall (210u) compared to the cartridge (200) of FIG. 2b. In this case, the upper wall (210u) may correspond to a component included in the housing (210) or a portion of the housing (210).

[0155] The opening (240a) may be positioned in a portion of the upper wall (210u). Compared to the cartridge (200) of FIG. 2B, the opening (240a) may be formed relatively small. For example, the opening (240a) may have a size corresponding to the inlet of the inlet (131) positioned in the main body (100).

[0156] Referring to Fig. 7b, in the cartridge (200b) illustrated in Fig. 7b, compared to the cartridge (200a) of Fig. 7a, the opening (240b) is positioned on the side wall (210s) rather than the upper wall (210u). In this case, the side wall (210s) may correspond to a component included in the housing (210) or a portion of the housing (210).

[0157] That is, the opening (240b) can be positioned to face the first surface (221) of the receiving portion (220). In response to the position of the opening (240b), an inlet of the inlet portion (131) can also be formed in the main body (100) of the inhaler at a position corresponding to the opening (240b).

[0158] Referring to FIG. 7c, in the cartridge (200c) illustrated in FIG. 7c, the passage portion (230c) is positioned at the bottom rather than the side of the receiving portion (220) compared to the cartridge (200a) of FIG. 7a.

[0159] Accordingly, the direction in which each part of the passage (230c) is opened or extended may also vary. For example, the air inlet (230ic) and the air intake (230ec) are opened in a first direction (e.g., z-axis direction), the first passage (231c) and the third passage (233c) are extended in a second direction (e.g., x-axis direction), and the second passage (232c) connecting the two passages may be extended in the first direction.

[0160] Meanwhile, up to now, the first direction, which is the direction in which the first surface (221) of the receiving portion (220) extends, has been described as the insertion direction of the cartridge (200) into the main body (100), but depending on the embodiment, the second direction crossing the first direction may be the insertion direction of the cartridge (200). In this case, the main body (100) is open toward the lower portion of the body (110), and the concept of the cartridge (200) being coupled through the open lower portion of the body (110) is the same.

[0161] When explaining the cartridge (200a) illustrated in Fig. 7a as an example, when the cartridge (200) is coupled through the open lower part of the main body (100) with the second direction as the insertion direction of the cartridge (200), the passage part (230) may be arranged at the upper part of the receiving part (220), and the opening part (240a) may be arranged at the lower side part of the receiving part (220). Corresponding to the positions of the passage part (230) and the opening part (240a), a hole through which air enters and an inlet part (131) of the flow path (130) may also be arranged in the main body (100).

[0162] Figure 8 is a perspective view of a cartridge according to another embodiment to which a blocking member is applied.

[0163] Referring to FIG. 8, a cartridge (200) according to another embodiment may further include a blocking portion (270) and a rail portion (280) compared to the cartridge (200) of FIG. 2a. In describing FIG. 8 below, reference will be made to the drawing symbols of FIG. 4.

[0164] The blocking portion (270) is configured to cover the opening (240). By blocking at least a portion of the opening (240) with the blocking portion (270), the receiving portion (220) can be blocked from the outside of the housing (210).

[0165] The blocking member (270) can be detachably coupled to the housing (210). For this purpose, a rail member (280) can be placed on the upper portion of the housing (210). The rail member (280) may be an integral part of the housing (210) or may be an independent part of the housing (210).

[0166] The rail portions (280) are arranged in pairs and may have an 'L' shape that is turned upside down. The blocking portion (270) can be inserted by sliding between the pair of rail portions (280). In this manner, the blocking portion (270) can be coupled to the rail portion (280) and can also be separated from the rail portion (280).

[0167] However, the method by which the blocking part (270) is coupled to the housing (210) is not limited to the method using the rail part (280). Depending on the embodiment, the blocking part (270) may be detachably coupled to the housing (210) in various ways.

[0168] Instead of the blocking portion (270) blocking the opening (240), the blocking portion (270) may include an air outlet (270h) that fluidly connects the exterior of the housing (210) and the receiving portion (220). The air outlet (270h) may be connected to the inlet portion (131) of the main body (100). That is, the air outlet (270h) formed in the blocking portion (270) may correspond to the outlet of the cartridge (200) through which air passes while carrying the target material.

[0169] Figures 9a and 9b are cross-sectional views of an inhaler according to another embodiment equipped with a cartridge that can be used upside down.

[0170] Referring to FIGS. 9A and 9B, an inhaler (1) according to another embodiment may include a main body (100) and a cartridge (300). At least one of the components of the inhaler (1) illustrated in FIGS. 9A and 9B may be identical or similar to at least one of the components of the inhaler (1) illustrated in FIG. 4, and any redundant description thereof will be omitted below.

[0171] The cartridge (300) illustrated in FIGS. 9A and 9B can be used upside down, compared to the cartridge (200) illustrated in FIG. 2B. That is, the cartridge (300) can be mounted on the main body (100) in the direction illustrated in FIG. 9A, and can also be mounted on the main body (100) in the direction illustrated in FIG. 9B.

[0172] Specifically, regarding the cartridge (300) that can be used even when turned upside down, the cartridge (300) may have two receiving portions (320), two passage portions (330), and two opening portions (340) in one housing (310).

[0173] The receiving portion (320) may include a first receiving portion (320A) and a second receiving portion (320B). The passage portion (330) may include a first passage portion (330A) and a second passage portion (330B). The opening portion (340) may include a first opening portion (340A) and a second opening portion (340B).

[0174] As described above, the first passage (330A), the first receiving portion (320A), and the first opening (340A) can be fluidly connected, and the second passage (330B), the second receiving portion (320B), and the second opening (340B) can be fluidly connected.

[0175] The cartridge (300) may include a partition wall (325) that separates a first receiving portion (320A) and a second receiving portion (320B). The partition wall (325) may be positioned between the first receiving portion (320A) and the second receiving portion (320B). A target substance may be stored in each of the first receiving portion (320A) and the second receiving portion (320B) divided by the partition wall (325).

[0176] The partition wall (325) may provide inclined surfaces to the first receiving portion (320A) and the second receiving portion (320B). For example, the second surface (322A) of the first receiving portion (320A) may correspond to one surface of the partition wall (325), and the second surface (322B) of the second receiving portion (320B) may correspond to the other surface of the partition wall (325) facing in the opposite direction from the one surface of the partition wall (325).

[0177] According to this structure, the concept of arranging a slope in the receiving portion (320) can be maintained while maximizing the capacity of the cartridge (300) capable of storing the target substance. In addition, since the two receiving portions (320) are separated by a partition wall (325), different types of target substances can be stored in each receiving portion (320). In this case, the user can inhale the target substance of his / her choice by turning the cartridge (300) upside down and mounting it on the main body (100) at any time.

[0178] Meanwhile, as explained above, since the passage part (330) has a shape that is bent at least once, it may be difficult for the target material stored in the receiving part (320) to leak out through the two passage parts (330) regardless of the direction in which the cartridge (300) is mounted.

[0179] However, since the two openings (340) are open to the upper and lower portions of the housing (310), a problem may arise in which the target material leaks out through the openings (340). For example, as illustrated in FIG. 9A, when the first opening (340A) is positioned at the upper portion of the housing (310) and connected to the flow path (130) of the main body (100), the second opening (340B) is positioned at the lower portion of the housing (310), so the target material stored in the second receiving portion (320B) may spill out through the second opening (340B).

[0180] Below, a configuration arranged to solve the problem of target material leaking through the opening (340) will be described.

[0181] Fig. 10a is a cross-sectional view of a cartridge according to another embodiment in which a door is applied to the cartridge of Fig. 9a. Fig. 10b is a cross-sectional view of a cartridge according to another embodiment in which the cartridge blocking member of Fig. 9a is applied.

[0182] The cartridges (300) illustrated in FIGS. 10a and 10b each correspond to separate embodiments for solving the problem of leakage through the opening (340).

[0183] At least one of the components of the cartridge (300) illustrated in FIGS. 10a and 10b may be identical or similar to at least one of the components of the cartridge (300) illustrated in FIGS. 9a and 9b, and any redundant description thereof will be omitted below.

[0184] Referring to FIG. 10A, the cartridge (300) illustrated in FIG. 10A may further include a door (360A, 360B) compared to the cartridge (300) illustrated in FIG. 9A.

[0185] The door (360A, 360B) is configured to slide to open and close the passageway (330) or the opening (340). At least a portion of the door (360A, 360B) can be accommodated in a sliding groove (315A, 315B) formed in the housing (310). The door (360A, 360B) and the sliding groove (315A, 315B) are similar to the door (260) and the sliding groove (215) illustrated in FIG. 6, and therefore, any description of overlapping content will be omitted.

[0186] Two doors (360A, 360B) may be arranged. Specifically, the doors (360A, 360B) may include a first door (360A) that opens and closes a first passageway (330A) or a second opening (340B), and a second door (360B) that opens and closes a second passageway (330B) or a first opening (340A). The first door (360A) and the second door (360B) may move independently.

[0187] In response to the two doors (360A, 360B), two sliding grooves (315A, 315B) may also be formed in the housing (310). That is, the sliding grooves (315A, 315B) may include a first sliding groove (315A) that accommodates a first door (360A) and a second sliding groove (315B) that accommodates a second door (360B).

[0188] Referring to the drawing, the cartridge (300) is positioned in a direction such that the target substance stored in the first receiving portion (320A) can be inhaled. Accordingly, the target substance stored in the first receiving portion (320A) can move to the main body through the first opening (340A), and the target substance stored in the second receiving portion (320B) can flow out of the inhaler through the second opening (340B).

[0189] To prevent the target substance from leaking through the second opening (340B), the second opening (340B) must be closed. To this end, the first door (360A) can move along the first sliding groove (315A) to close the second opening (340B). At the same time, the first door (360A) can open the first passageway (330A) to allow the user to use the inhaler.

[0190] Since the first opening (340A) must be opened for inhalation of the target substance, the second door (360B) can move along the second sliding groove (315B) to open the first opening (340A). At the same time, in order to prevent the target substance stored in the second receiving portion (320B) from flowing out through the second passage (330B) and to prevent foreign substances from entering through the second passage (330B), the second door (360B) can close the second passage (330B). However, since the air inlet of the second passage (330B) is arranged to face the main body of the inhaler, it is covered by the main body and is not exposed to the outside of the inhaler. Therefore, in this case, the closing of the second passage (330B) may be somewhat less important.

[0191] As shown, when the door (360A, 360B) closes the opening (340), the passage (330) can be opened, and when the door (360A, 360B) closes the passage (330), the opening (340) can be opened. However, the embodiment is not limited to this opening and closing method.

[0192] As another example, the doors (360A, 360B) may simultaneously open and close the opening (340) and the passageway (330). As another example, the doors (360A, 360B) are respectively arranged in the opening (340) and the passageway (330), so that each door (360A, 360B) can independently open and close the opening (340) and the passageway (330).

[0193] Referring to FIG. 10b, the cartridge (300) illustrated in FIG. 10b may further include a blocking portion (370A, 370B) compared to the cartridge (300) illustrated in FIG. 9a.

[0194] The blocking portions (370A, 370B) are configured to be detachably coupled to a portion of the housing (310) to open and close the passage portion (330) or the opening portion (340). The blocking portions (370A, 370B) can be coupled to the housing (310) using a rail portion (not shown) arranged on the housing (310). The blocking portions (370A, 370B) and the rail portion are similar to the blocking portion (270) and the rail portion illustrated in FIG. 8, and therefore, description of overlapping content will be omitted.

[0195] Two blocking sections (370A, 370B) may be arranged. Specifically, the blocking sections (370A, 370B) may include a first blocking section (370A) that opens and closes the first passage section (330A) or the second opening section (340B), and a second blocking section (370B) that opens and closes the second passage section (330B) or the first opening section (340A). In correspondence with the two blocking sections (370A, 370B), two rail sections may also be arranged.

[0196] The blocking parts (370A, 370B) can be coupled to the housing (310) in a state in which they are symmetrical left and right (e.g., rotated 180 degrees around the z-axis) or flipped 180 degrees around the y-axis in the illustrated state. Accordingly, a user can couple the blocking parts (370A, 370B) to the housing (310) without distinguishing between the left and right or the top and bottom of the blocking parts (370A, 370B).

[0197] The blocking portion (370A, 370B) may include an inlet opening (371A, 371B) connected to the passage portion (330) and an outlet opening (372A, 372B) connected to the opening (340). However, when the blocking portion (370A, 370B) is coupled to the housing (310), the inlet opening (371A, 371B) and the outlet opening (372A, 372B) cannot be simultaneously connected to the passage portion (330) and the opening (340), respectively.

[0198] For example, if the introduction openings (371A, 371B) of the two blocking parts (370A, 370B) are connected to the passage part (330), the discharge openings (372A, 372B) cannot be connected to the openings (340). In this state, if the user rotates the blocking parts (370A, 370B) 180 degrees around the y-axis and turns them upside down to couple the blocking parts (370A, 370B) to the housing (310), the discharge openings (372A, 372B) can be connected to the openings (340), but the introduction openings (371A, 371B) cannot be connected to the passage part (330).

[0199] Accordingly, when the user wants to close the second opening (340B) located at the bottom of the housing (310), the first blocking portion (370A) can be coupled to the housing (310) as shown. In this case, the first blocking portion (370A) can close the second opening (340B). At the same time, the first passage portion (330A) can be opened by being connected to the first introduction opening (371A) so that the user can use the inhaler. At this time, the first discharge opening (372A) can be located at a location unrelated to the location of the second opening (340B).

[0200] The first opening (340A) located at the top of the housing (310) must be open, so that the user can couple the second blocking member (370B) to the housing (310) as shown.

[0201] In this case, the first opening (340A) can be opened by being connected to the second discharge opening (372B). At the same time, the second passageway (330B) can be closed by the second blocking section (370B). At this time, the second introduction opening (372B) can be located at a location unrelated to the location of the second passageway (330B).

[0202] Below, an example of a method of combining a cartridge and a main body is described.

[0203] Figures 11a and 11b are perspective views showing the main body of the inhaler and the cartridge separated therefrom, respectively, according to embodiments to which a fastening structure is applied.

[0204] Referring to FIGS. 11A and 11B, an inhaler (1) according to another embodiment may include a main body (100) and a cartridge (400A, 400B).

[0205] Referring to FIG. 11A, an embodiment is illustrated in which a cartridge (400A) approaches the lower portion of the main body (100) as described above and is inserted into the main body (100) in the longitudinal direction of the main body (100) (e.g., z-axis direction).

[0206] Referring to FIG. 11B, an embodiment is illustrated in which a cartridge (400B) approaches the side of the main body (100) and is inserted into the main body (100) in a direction transverse to the longitudinal direction of the main body (100) (e.g., x-axis direction).

[0207] The main body (100) of the inhaler (1) of FIGS. 11A and 11B may commonly include an operating portion (190A, 190B). The operating portion (190A, 190B) is a configuration used to detachably couple the cartridge (400A, 400B) to the main body (100). At this time, only the button among the sub-components of the operating portion (190A, 190B) may be exposed on the outside of the main body (100).

[0208] The cartridge (400A, 400B) can be interlocked and combined with a portion of the operating unit (190A, 190B). To this end, a fastening groove is formed in a region of the housing (410) of the cartridge (400A, 400B), and a step portion (490A, 490B) can be placed in the region where the fastening groove is formed.

[0209] The step portion (490A, 490B) may protrude inside the fastening groove in a direction transverse to the direction in which the groove is dug in the housing (410). At this time, the step portion (490A, 490B) may be a component included in the housing (410) or may be a sub-component of a cartridge (400A, 400B) handled separately from the housing (410).

[0210] Referring to Fig. 11a, a fastening groove and a step portion (490A) are arranged on the upper portion of a cartridge (400A) approaching the lower portion of the main body (100). At this time, considering the arrangement of the opening (440), the fastening groove and the step portion (490A) may be arranged on each side of the opening (440).

[0211] Referring to Fig. 11b, a fastening groove and a step portion (490B) are arranged on the side of the cartridge (400B) approaching the side of the main body (100). As shown, the fastening groove is formed to cross one side of the side of the cartridge (400B), but the embodiment is not necessarily limited thereto.

[0212] Below, the fastening structure of the main body (100) and the cartridge (400B) will be described in detail based on the embodiment illustrated in Fig. 11b.

[0213] Fig. 12 is a perspective view of the inhaler body and cartridge shown in Fig. 11b from a different angle to explain the internal structure of the inhaler body.

[0214] Referring to FIG. 12, an inhaler (1) according to another embodiment may include a main body (100) and a cartridge (400).

[0215] At least one of the components of the inhaler (1) illustrated in FIG. 12 may be identical or similar to at least one of the components of the inhaler (1) illustrated in FIG. 11b, and any redundant description thereof will be omitted below.

[0216] Referring to Fig. 12, the cartridge (400) can be inserted into the interior of the main body (100) through the side of the main body (100). At this time, Fig. 12 illustrates the interior of the receiving space (110i) of the body (110).

[0217] As shown, at least a part of the operating unit (190) is not shown because it is covered by a cover plate (115). In this case, the cover plate (115) may correspond to a component of the body (110) or may be a sub-component of the main body (100) that is treated separately from the body (110).

[0218] If only the configuration of the operating unit (190) illustrated in Fig. 12 is described, the operating unit (190) may include a button (1911) and a fastening member (1921).

[0219] The button (1911) is positioned so that at least a portion of it is exposed to the outside of the body (110), and can serve to release the fastening relationship between the body (100) and the cartridge (400) according to a user's input. For example, when a user's input is applied to the button (1911), the cartridge (400) can be detached from the body (100).

[0220] The fastening member (1921) is configured to be engaged with the step portion (490) of the cartridge (400) and seated in the fastening groove (410g). By moving the fastening member (1921) up and down, the cartridge (400) can be fastened to the main body (100) or can be separated from the main body (100).

[0221] Fig. 13a is an exploded front view showing the inhaler body illustrated in Fig. 12 in a first operating state. Fig. 13b is an exploded front view showing the inhaler body illustrated in Fig. 12 in a second operating state.

[0222] At this time, the 'first operating state' means a state in which no input is applied to the button (1911), and thus the cartridge (e.g., cartridge (400) of FIG. 12) is maintained mounted on the main body (100), and the 'second operating state' means a state in which a user input is applied to the button (1911), and thus the cartridge is allowed to be mounted or removed from the main body (100). The expressions may be used with the same meaning below.

[0223] Referring to FIGS. 13a and 13b, a main body (100) of an inhaler (1) according to another embodiment may include a body (110) and an operating portion (190). At this time, the operating portion (190) may include a first moving member (191), a second moving member (192), and an elastic member (193).

[0224] The first movable member (191) is configured to slide horizontally according to the user's operation. The first movable member (191) may include a button (1911) and a first guide hole (1912).

[0225] The button (1911) is positioned so that at least a portion thereof is exposed to the outside of the body (110) and may be positioned at one end of the first movable member (191). When the user presses the button (1911) to move the button (1911), the first movable member (1911) may also move along with it.

[0226] The first guide hole (1912) is formed in one area of ​​the first movable member (191) and is a hole extending in a horizontal direction, which is the movement direction of the first movable member (191). A first guide protrusion (P1) can be inserted into the first guide hole (1912). The first guide protrusion (P1) is arranged inside the body (110) and is configured to be fixed at one position.

[0227] A first guide protrusion (P1) is inserted into a first guide hole (1912) extending in a horizontal direction, so that the first movable member (191) can move only in a horizontal direction. In addition, since the first guide protrusion (P1) comes into contact with a portion of the first movable member (191) at both ends of the first guide hole (1912), the horizontal movement of the first movable member (191) can be restricted.

[0228] The second movable member (192) is configured to be slidable in a vertical direction by the sliding movement of the first movable member (191) by interlocking with the first movable member (191). The second movable member (192) may include a fastening member (1921) and a second guide hole (1922).

[0229] The fastening member (1921) is positioned to be exposed to the receiving space (e.g., the receiving space (110i) of FIG. 12) as illustrated in FIG. 12, and can move together with the second moving member (192).

[0230] The second guide hole (1922) is formed in one area of ​​the second movable member (192) and is a hole extending in a vertical direction, which is the movement direction of the second movable member (192). A second guide protrusion (P2) can be inserted into the second guide hole (1922). The second guide protrusion (P2) is arranged inside the body (110) and is configured to be fixed in one position.

[0231] A second guide protrusion (P2) is inserted into a second guide hole (1922) extending in a vertical direction, so that the second movable member (192) can move only in the vertical direction. In addition, since the second guide protrusion (P2) comes into contact with a portion of the second movable member (192) at both ends of the second guide hole (1922), the vertical movement of the second movable member (192) can be restricted.

[0232] A portion of the surface where the first movable member (191) and the second movable member (192) come into contact may be an inclined surface. Accordingly, the second movable member (192) can move vertically by the force applied by the first movable member (191) through the inclined surface. Conversely, the first movable member (191) can also move horizontally by the force applied by the second movable member (192) through the inclined surface.

[0233] The elastic member (193) is configured to elastically pressurize the second movable member (192) in a direction (e.g., vertically upward) toward the first movable member (191). When the second movable member (192) moves in a vertically downward direction due to the pressing of the first movable member (191), the elastic member (193) can be compressed.

[0234] The compressed elastic member (193) can apply elastic force to the second movable member (192), thereby restoring the second movable member (192) to its position when no pressure is applied. Accordingly, the first movable member (191) can also move to its position when no pressure is applied.

[0235] Below, the movement of the first moving member (191) and the second moving member (192) based on the user's input to the button (1911) will be described in detail.

[0236] Referring to Fig. 13a, the main body (100) in a first operating state is illustrated. In a state where no pressure is applied, the first movable member (191) is positioned so that the button (1911) is exposed to the outside of the body (110). At this time, the first movable member (191) may be moved to the left as much as possible. The second movable member (192) may also be moved upward as much as possible. Accordingly, the fastening member (1921) may also be moved upward as much as possible.

[0237] Referring to Fig. 13b, the main body (100) in the second operating state is illustrated. When the user presses the button (1911), the first movable member (191) can move horizontally inwardly of the main body (100). As a result, the second movable member (192) can move vertically downwardly of the main body (100), and the elastic member (193) in contact with the lower portion of the second movable member (192) can be compressed. At this time, the first movable member (191) can be moved to the right as much as possible. The second movable member (192) can also be moved downward as much as possible. Accordingly, the fastening member (1921) can also be moved downward as much as possible.

[0238] When the user presses the button (1911) so that the fastening member (1921) moves downward, the cartridge (400) can be separated from the main body (100). After the cartridge (400) is separated and the pressure on the button (1911) is released, the internal components of the main body (100) can be restored to the first operating state by the elastic force of the elastic member (193).

[0239] Figure 14a is a cutaway side view schematically illustrating how the fastening groove of the cartridge is coupled to the inhaler body through fastening with a fastening member in the first operating state. Figure 14b is a cutaway side view schematically illustrating how the fastening groove of the cartridge is coupled to the inhaler body through fastening with a fastening member in the second operating state.

[0240] In describing FIGS. 14a and 14b below, reference will be made to the drawing symbols of FIG. 12.

[0241] Referring to FIGS. 14a and 14b, the fastening member (1921) may include a stopper (1921_st) that protrudes upward. The fastening groove (410g) may be formed to be retracted upward to accommodate the stopper (1921_st).

[0242] When in the first operating state, the stopper (1921_st) can be accommodated in the fastening groove (410g) to limit movement of the cartridge (400) in the x-axis direction. In addition, when in the second operating state, the stopper (1921_st) can move downward and be separated from the fastening groove (410g) to allow movement of the cartridge (400) in the x-axis direction.

[0243] Specifically, the stopper (1921_st) may include a sloped portion (1921_ip). In order to mount the cartridge (400) on the main body (100) in a state where the user does not input the button (1911) (e.g., a first operating state), when the cartridge (400) is pushed toward the main body (100) at a height where the fastening groove (410g) and the stopper (1921_st) correspond to each other, the outer edge of the protrusion (490) of the cartridge (400) may come into contact with the sloped portion (1921_ip) of the stopper (1921_st), as illustrated in FIG. 9A.

[0244] In this state, when the cartridge (400) is pushed further toward the main body (100), the outer edge of the step portion (490) slides against the inclined portion (1921_ip), thereby moving the stopper (1921_st) downward. At this time, the stopper (1921_st) can move downward until the upper surface of the stopper (1921_st) comes into contact with the lower surface of the step portion (490).

[0245] When the cartridge (400) continues to be pushed toward the main body (100) while the upper surface of the stopper (1921_st) is in contact with the lower surface of the step portion (490), the stopper (1921_st) can reach the fastening groove (410g).

[0246] Then, the upper surface of the stopper (1921_st) no longer comes into contact with the lower surface of the step portion (490). The stopper (1921_st) can move upward in the fastening groove (410g) and be fitted into the fastening groove (410g). At this time, the position of the stopper (1921_st) may be the same as the position of the stopper (1921_st) before moving downward.

[0247] Through the above-described process, the fastening member (1921) is accommodated in the fastening groove (410g) so that the cartridge (400) can be mounted on the main body (100).

[0248] According to the structure described above, the user can mount the cartridge (400) into the main body (100) without inputting the button (1911).

[0249] Of course, as shown in Fig. 9b, in a state where a user input is applied to the button (1911) (e.g., the second operating state), the cartridge (400) can be easily mounted on the main body (100) without contact between the inclined portion (1921_ip) of the stopper (1921_st) and the cartridge (400).

[0250] However, when attempting to separate the cartridge (400) from the main body (100), the user must press the button (1911) to move the stopper (1921_st) downward.

[0251] In summary, mounting the cartridge (400) on the main body (100) is possible in the first operating state and also in the second operating state, but mounting is easier in the second operating state. Separating the cartridge (400) from the main body (100) is only possible in the second operating state.

[0252] That is, in order to maintain the state in which the cartridge (400) is mounted on the main body (100), the inhaler must maintain a first operating state in which movement of the cartridge (400) in the x-axis direction is restricted.

[0253] According to the cartridge and the inhaler including the same according to the embodiments, an inclined surface is arranged in the receiving portion where the target substance is stored, so that air can easily transport the target substance, and thus the target substance can be effectively supplied to the user.

[0254] Additionally, according to the cartridge and the inhaler including the same according to the embodiments, the complex shape of the passage (e.g., a shape bent at least once) can prevent the target substance from leaking through a part other than the mouthpiece.

[0255] In addition, according to the cartridge and the inhaler including the same according to the embodiments, a cyclone structure can be used to prevent particles larger than a certain size from entering the user and improve the inhalation sensation of the target substance.

[0256] Any or all of the embodiments of the present disclosure described above are not mutually exclusive or distinct. Any or all of the embodiments of the present disclosure described above may have their respective components or functions combined or used together.

[0257] For example, it means that a configuration A described in a particular embodiment and / or drawing can be combined with a configuration B described in another embodiment and / or drawing. That is, even if a combination between configurations is not directly described, it means that a combination is possible, except in cases where a combination is described as impossible.

[0258] The above detailed description should not be construed as limiting in any respect and should be considered illustrative only. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are intended to be included within the scope of the present invention.
