[0034] Figure 7 is a cross-sectional view of the slide portion 400 of the inhaler 10 according to one embodiment.

[0035] Referring to Figures 1 to 3, an inhaler 10 according to one embodiment includes a mouthpiece 100, a housing 200, a piercing part 300, a sliding part 400, and a storage part 500. The elements constituting the inhaler 10 according to one embodiment may be made of materials such as PLA, ABS, PC, PP, or other biodegradable (environmentally friendly) materials. Alternatively, they may be made of metal such as aluminum. The inhaler 10 may be manufactured via a 3D printer.

[0036] The mouthpiece 100 is formed in a cylindrical shape extending in the longitudinal direction, and an air inlet can be formed on the side. One end of the mouthpiece 100 is shaped to be easily bitten by the user, preferably in the shape of a circle or ellipse, and the mouthpiece 100 is shaped to be suitable for storing the capsule C and can form an internal space larger than the capsule C. In such an internal space, a spiral structure may be formed on the inner wall to generate the formation of a rotating airflow near the capsule C. The other end of the mouthpiece 100 has a capsule C containing a functional substance inserted into it. The size of the capsule C may be, for example, size 0, 1, 2, 3, 4, 5, and preferably size 3. The functional substance may be, for example, nicotine, nicotine salt, caffeine, taurine, vitamins, or preferred inhalation substances, and may also contain other pharmacological substances. The functional substance may be contained in the capsule C in the form of a dry powder, for example. Here, the size of the dry powder is about 5 to 10 μm, and may contain menthol particles of 20 μm or more. Such dry powder may or may not have a carrier. Here, the size of the carrier is 20-50 μm or larger, and may be around 100 μm. One end of the mouthpiece 100 that the user comes into contact with may have a mesh screen for separating particles coming out of capsule C. The material of the mesh screen may be made of PLA or the same as the material of the housing 200, or it may be made of a chemically stable, non-inhalation toxic metal such as stainless steel. After the powder inside capsule C is consumed, capsule C can be replaced by separating the mouthpiece 100 from the housing 200.

[0037] The housing 200 can be provided in various shapes that are easy for the user to handle, such as circular or square. The size of the housing 200 may be, for example, 30-50 mm in width, 10-30 mm in height, and 50-70 mm in height. The housing 200 may be open at one end, with a cylindrical space extending from one end to the other. The mouthpiece 100 is inserted into the interior of the housing 200 via one end. Inside such a housing 200, a guide is formed for connecting the mouthpiece 100 from one end of the housing 200. In addition, a separate guide may be formed inside the housing 200, separate from the aforementioned guide. This guide is for guiding the movement path of the mouthpiece 100 when attempting to pierce the capsule C with the piercing portion 300. This guide may be formed separately from the guide extending from one end to allow the mouthpiece 100 to move further toward the other end of the housing 200 so that it reaches the piercing portion 300.

[0038] Referring to Figures 2 and 3, the piercing portion 300 may be located inside the housing 200. The piercing portion 300 may be located at the other end of the housing 200. Such a piercing portion 300 may extend toward one end. The piercing portion 300 may pierce the capsule C. The piercing portion 300 may also be coupled to a replaceable structure from the other end of the housing 200 for separate maintenance. For example, the piercing portion 300 may be provided by a needle. The piercing portion 300 is provided by one needle, but preferably two needles are arranged in parallel. The two needles may be the same length or different in length, and the needles of the other length may have a variety of diameters. The diameter of the needle may be, for example, 0.5 to 1.2 mm, preferably 0.7 mm.

[0039] The sliding portion 400 can be positioned to slide within the housing 200. As previously mentioned, the housing 200 may have an internal structure with protrusions and indentations to prevent the sliding portion 400 from detaching from its path. Through such a structure, the sliding portion 400 can move parallel to the piercing portion 300 when the mouthpiece 100 and the sliding portion 400 descend for piercing capsule C. The end of the mouthpiece 100 may be connected to the sliding portion 400. When the sliding portion 400 slides, the mouthpiece 100 moves with it.

[0040] The storage section 500 can form an internal space at a position separate from the space in the housing 200 where the mouthpiece is connected. Multiple capsules C may be housed in the storage section 500. For example, 1 to 20 capsules C may be stored in the storage section 500.

[0041] The storage compartment 500 may also be formed with an openable and closable structure. A door 510 may be formed at one end of the storage compartment 500. The door 510 may be implemented as a sliding structure, or it may be provided in the form of an opening and closing lid or a button-type opening and closing structure.

[0042] Referring to Figures 2 and 3, the inhaler 10 according to one embodiment may further include a spring 600.

[0043] The spring 600 can be connected at one end to the sliding portion 400 and at the other end to the other end of the housing 200. For example, the piercing portion 300, which consists of two needles, may be positioned at a distance smaller than the diameter of the spring 600 and surrounded by the spring 600.

[0044] Referring to Figure 2, when the mouthpiece 100 or the slide portion 400 is not being pressed by an external force, the spring 600 can support the slide portion 400 so that it is positioned away from the piercing portion 300 toward one end of the housing 200.

[0045] Referring to Figure 3, when the mouthpiece 100 or the slide portion 400 is pressurized and moves toward the other end of the housing 200, the spring 600 is compressed. As a result, the piercing portion 300 penetrates the slide portion 400 and the mouthpiece 100, puncturing the capsule C housed within the mouthpiece 100.

[0046] The capsule C may contain, for example, a functional substance in the form of a dry powder. As described above, when the capsule C is punctured by the piercing portion 300, the functional substance inside the capsule C becomes available for inhalation by the user. In addition, since the user inhales the functional substance with the capsule C fastened to the mouthpiece 100, the inhalation resistance is increased.

[0047] Referring to Figure 4, the housing 200 is open at one end, and a first guide groove 210, a second guide groove 220, and a third guide groove 230 are formed in the longitudinal direction in a cylindrical space extending from one end to the other.

[0048] The first guide groove 210 may start at one end of the housing 200 and extend to a first point P1 that moves away from the other end.

[0049] The second guide groove 220 can extend from the first point P1 to a second point P2 located circumferentially away from the housing 200.

[0050] The third guide groove 230 can extend from the second point P2 to the third point P3 adjacent to the other end of the housing 200.

[0051] Referring again to Figure 4, the housing 200 may further have guide rails 240 formed thereon.

[0052] The guide rail 240 extends from any point of height, such as the first point P1 or the second point P2, to the other end of the housing 200. The guide rail 240 protrudes inward from the housing 200.

[0053] The guide rail 240 restricts the mouthpiece 100 from sliding further down from the first point P1 once it has reached that point. The guide rail 240 can also be coupled to the mouthpiece 100 when it moves along the third guide groove 230 toward the other end of the housing 200.

[0054] Referring to Figure 5, the mouthpiece 100 includes a first connecting member 110 and a second connecting member 120 formed on the outside.

[0055] The first connecting member 110 may protrude radially from the other end of the mouthpiece 100. The first connecting member 110 is connected to the first guide groove 210, the second guide groove 220, or the third guide groove 230.

[0056] The second coupling member 120 may be formed as a groove extending from one end to the other of the mouthpiece 100, spaced circumferentially away from the first coupling member 110. The second coupling member 120 can be coupled to the guide rail 240.

[0057] The first coupling member 110 of the mouthpiece 100 is coupled to the first guide groove 210 from one end of the housing 200 and can move toward the first point P1. Therefore, the mouthpiece 100 can be inserted into the housing 200 until it reaches the first point P1. Here, the mouthpiece 100 can be prevented from rotating by the coupling between the first guide groove 210 and the first coupling member 110.

[0058] With the first connecting member 110 connected to the first guide groove 210, as described above, the sliding movement of the mouthpiece 100 toward the other end of the housing 200 via the first point P1 is restricted.

[0059] For the capsule C inside the mouthpiece 100 to be pierced by the piercing portion 300, the mouthpiece 100 needs to move further toward the other end of the housing 200. To this end, the first connecting member 110 moves to a second point P2 that is circumferentially separated from the first point P1 while remaining at the same height as the first point P1.

[0060] When the first connecting member 110 reaches the second point, the first connecting member 110 becomes movable along the third guide groove 230, and the second connecting member 120 is positioned to correspond to the guide rail 240 and becomes capable of connecting with the guide rail 240. When pressure is applied to the mouthpiece 100 positioned in this state, the mouthpiece 100 can slide toward the other end of the housing 200 via the first point P1 and the second point P2. As a result, the capsule C can reach the piercing portion 300 and be pierced.

[0061] As described above, the housing 200 is equipped with individually provided first guide grooves 210, second guide grooves 220, third guide grooves 230, and guide rails 240, which facilitates the coupling of the mouthpiece 100 to the housing 200 and prevents the mouthpiece 100 from rotating or detaching from the housing 200 after coupling. Furthermore, by allowing rotation of the mouthpiece 100 only at specific points where the second guide groove 220 is located, and guiding the mouthpiece 100 to move parallel to the piercing portion 300, the piercing of the capsule C can be facilitated.

[0062] Referring again to Figure 5, the mouthpiece 100 may further include a housing member 140 and a bottleneck member 130.

[0063] The housing member 140 is a cavity formed adjacent to the other end of the mouthpiece 100. The capsule C is housed in the housing member 140.

[0064] The bottleneck member 130 is formed adjacent to the housing member 140. The bottleneck member 130 may be formed with a smaller diameter than the housing member 140. Depending on the shape of the bottleneck member 130, the movement of the capsule C housed in the housing member 140 toward one end of the mouthpiece 100 is restricted. In addition, the bottleneck member 130 can prevent distortion of the capsule C when the piercing portion 300 pierces the capsule C.

[0065] Referring to Figure 6, the sliding portion 400 includes a moving member 410, a mounting member 420, a guide groove 430, a protruding member 440, and a through hole 450.

[0066] The movable member 410 may have a cylindrical body. The movable member 410 can slide within the housing 200.

[0067] The mounting member 420 is formed on one surface of the movable member 410. Multiple mounting members 420 may be provided. Here, the multiple mounting members 420 may be spaced apart in the circumferential direction of the movable member. The mounting member 420 may protrude from one surface of the movable member 410 toward one end of the housing 200. Alternatively, the mounting member 420 may be formed such that its central portion is recessed in the direction opposite to the direction toward one end of the housing 200 from one surface of the movable member 410.

[0068] The mounting member 420 may be formed, for example, by two steps. As shown in Figures 6 and 7, the mounting member 420 may be formed by steps such that the height of the protrusion from one surface of the movable member 410 decreases as it approaches the center. The capsule C is placed on such a mounting member 420. Depending on the shape of the steps of the mounting member 420, the capsule C does not come into contact with one surface of the movable member 410, so that an air inflow space can be secured between the surface and the capsule C. Therefore, in the inhaler 10 according to one embodiment, the airflow is smooth, and the user can easily inhale the functional substance inside the capsule C while the capsule C is fastened to the mounting member 420.

[0069] In the two stepped structures of the mounting member 420, at least a portion of the two stepped structures on the side facing one end of the housing 200 (for example, the upper part of the mounting member 420 in Figure 7) may have an inclined structure. Such an inclined structure can smoothly guide the vertical uprighting of the capsule C. Through the inclined structure, the diameter of the housing space formed by the mounting member 420 may be larger than the diameter of the capsule C, and by ensuring sufficient space to accommodate the capsule C, the rotation of the capsule C can be smoothly guided when air flows in through the intake.

[0070] On the other hand, an additional step can be formed on the upper end of the mounting member 420 (for example, the upper part of the mounting member 420 in Figure 7). The mouthpiece 100 is placed on this additional step, and the mouthpiece 100 does not come into contact with one surface of the movable member 410.

[0071] The guide grooves 430 can be formed on the side surface of the movable member 410. Multiple guide grooves 430 may be provided, with each guide groove 430 located between two spaced-apart mounting members 420. At least one of the multiple guide grooves 430 is connected to the guide rail 240. Therefore, when the sliding part 400 moves inside the housing 200, it can move along the guide rail 240, preventing it from rotating during movement.

[0072] The protruding member 440 can be formed on the other side of the movable member 410. The protruding member 440 may protrude cylindrically from the other side of the movable member 410 toward the other end of the housing 200. The diameter of the protruding member 440 may be smaller than the diameter of the movable member 410. One end of the spring 600 can be connected to the protruding member 440. Therefore, the movable member 410 can efficiently compress the spring 600.

[0073] Referring to Figure 7, the through-hole 450 can be formed to penetrate the movable member 410 in the same direction as the movable member 410's movement. In such a through-hole 450, the piercing portion 300 passes through when the movable member 410 slides from one end of the housing 200 to the other end. The through-hole 450 may be formed in a trumpet shape. For example, the diameter of the opening adjacent to the other end of the housing 200 may be larger than the diameter of the opening adjacent to one end of the housing 200. Such a shape of the through-hole 450 allows the piercing portion 300 to pass through the through-hole 450 smoothly and easily reach the capsule C.

[0074] An inhaler 10 according to one embodiment may further include a stopper (not shown). Referring to Figures 2 and 3, small-sized air holes 700 can be formed on the side of the housing 200 to facilitate the smooth formation of airflow when negative pressure is formed. The stopper is inserted into the air holes 700 of the housing 200. The stopper is inserted such that one end is located outside the housing 200 and the other end is located inside the housing 200 of the sliding portion 400. Here, the other end of the stopper is inserted inside the housing 200 so that it is located further inside than the outer circumference of the movable member 410. Such a stopper can prevent shock due to the elasticity of the spring 600 when the sliding portion 400 moves up and down.

[0075] Furthermore, the stopper has an air inlet that penetrates its interior. The air inlet allows the air inflow space between the mouthpiece 100 and the slide portion 400 to communicate with the outside of the housing 200. In other words, the air inlet of the stopper acts as an air vent in the housing 200. Therefore, in one embodiment of the inhaler 10, the airflow from the outside to the air inflow space is smooth, allowing the user to easily inhale the functional substance inside the capsule C.

[0076] As described above, the inhaler 10 according to one embodiment is easily portable for timely inhalation of functional substances, can store multiple capsules C containing functional substances, and facilitates the replacement of capsules C by detaching the mouthpiece 100.

[0077] As described above, embodiments of the present invention have been explained by embodiments and drawings that are limited to specific matters such as concrete components, but these are provided to aid in a more general understanding of the present invention, and the present invention is not limited to the embodiments described above. Various modifications and variations can be made from such embodiments by a person with ordinary skill in the art to which the present invention belongs. For example, the described techniques may be performed in a different order than described, and / or the described structures, apparatus, and other components may be combined or combined in a different manner than described, or substituted or replaced by other components or equivalents, and still achieve the appropriate results. Therefore, the idea of ​​the present invention is not determined only by the described embodiments, and it is likely that all equivalent or equivalent variations of the claims described below will fall within the scope of the idea of ​​the present invention.
