[0005] Technical issues to be solved

[0006] One embodiment is directed to an inhaler that is capable of exhausting residual gas in a reservoir before filling the reservoir with an inhalable composition, thereby smoothly filling the reservoir.

[0007] The technical problems to be solved by this embodiment are not limited to the above-mentioned topics, and other topics not mentioned will be clearly understood by ordinary technicians in this field through the following description.

[0008] Technical solutions to the problem

[0009] To achieve the above-mentioned purpose, an inhaler according to an embodiment may include: a housing having a first surface, another surface opposite to the first surface, and a plurality of side surfaces connecting the first surface and the other surface; a storage member located inside the housing and storing an inhalable composition; a tank containing the inhalable composition to be stored in the storage member and connected in an openable and closable manner relative to the storage member, a pressure reducing valve separated from the tank and opening and closing the storage member relative to the outside; and a rod controlling the opening and closing of at least one of the tank or the pressure reducing valve, the rod performing control to open the tank after opening the pressure reducing valve.

[0010] According to one aspect, the invention may further include a pressure relief rod, one end of which is coupled to the pressure relief valve and extends toward the rod, the pressure relief rod being located between the rod and the tank.

[0011] According to one aspect, the rod may include: a support member extending in a first direction toward the tank; and a protrusion member, an end of which can be rotatably coupled to a rotation axis set on the support member, and the other end of the decompression rod is located between the protrusion member and the other side of the shell.

[0012] According to one aspect, when the rod is pressurized, as the protrusion moves in the first direction, the protrusion may move the decompression rod in a second direction toward one side of the housing.

[0013] According to one aspect, when pressure is applied to the rod in the first direction, the support member may restrict rotation of the protrusion member, and when the rod returns to an initial position, the support member may allow rotation of the protrusion member.

[0014] According to one aspect, the protrusion may be configured such that, when an end of the protrusion is in an upright position facing a surface of the housing, rotation toward the tank is not restricted, while rotation away from the tank is restricted.

[0015] According to one aspect, when the can is opened, the protrusion may be located between the pressure relief lever and the can.

[0016] According to one aspect, the rod may further include a wedge-shaped member extending toward a bottom surface of the tank, wherein a distance between the wedge-shaped member and the bottom surface of the tank is greater than a distance between the protrusion and the decompression rod.

[0017] According to one aspect, the wedge member includes an inclined surface, which is inclined along a first direction to be adjacent to the bottom surface. When pressure is further applied to the rod in the first direction while the inclined surface and the bottom surface are in contact, the inclined surface causes the tank to move along a second direction toward one side of the shell.

[0018] According to one aspect, when the rod reaches the first position to open the pressure reducing valve, the residual inhalable composition in the storage member is discharged to the outside; when the rod reaches the second position to open one side of the can, the inhalable composition in the can is filled into the storage member.

[0019] According to one aspect, the pressure reducing valve is opened when the pressure reducing rod moves in a second direction toward one side of the housing, and is closed when the pressure reducing rod returns to an initial position.

[0020] According to one aspect, the canister may include: a receiving portion receiving the inhalable composition; and an ejection port connected to the storage member on one side and located within the receiving portion on the other side, the ejection port being opened and closed to allow or restrict the inhalable composition from entering the storage member.

[0021] According to one aspect, when the accommodating portion moves in a second direction from the other surface toward the one surface of the housing, the ejection port is opened, and when the accommodating portion returns to an initial position, the ejection port is closed.

[0022] Effects of the Invention

[0023] The effect of the inhaler according to one embodiment is as follows: before the inhalable composition is filled into the reservoir, the residual gas in the reservoir is exhausted, thereby smoothly filling the reservoir.

[0024] The effects of the inhaler according to an embodiment are not limited to the above effects, and other effects not mentioned will be clearly understood by those skilled in the art through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Figure 1 is a perspective view of an inhaler 10 according to an embodiment.

[0035] Figure 2 is a cross-sectional view of an inhaler 10 according to an embodiment.

[0036] Figure 3 A pressure relief valve 700 is shown in conjunction with the stem 300 .

[0037] Figure 4 A two-stage operation of lever 300 is shown.

[0038] Figure 5 The rod 300 is shown in accordance with Figure 4 The sequential operation shown is the opening and closing operation of the pressure reducing valve 700 and the tank 200.

[0039] Reference Figure 1 , an inhaler 10 according to an embodiment includes a housing 101 , a mouthpiece 102 , a storage member 103 , a canister 200 , and a rod 300 .

[0040] The housing 101 may include a first surface formed on one side, a second surface opposite to the first surface, and a plurality of side surfaces connecting the first surface and the second surface. For example, the first surface of the housing 101 may be a surface located at the top of the housing 101, and the second surface may be a bottom surface of the housing 101.

[0041] The mouthpiece 102 may be disposed on the first surface of the housing 101. The user may inhale the inhalable composition in the inhaler 10 through the mouthpiece 102. At this time, for example, the user may inhale the composition in an aerosol state or a powder state. Hereinafter, the inhaler 10 according to an embodiment will be described by taking the inhaler 10 spraying the inhalable composition in an aerosol state as an example.

[0042] Reference Figure 1 and Figure 2 , the storage part 103 may be disposed inside the housing 101. Since the storage part 103 is connected to one side of the tank 200, the inhalable composition in the tank 200 can be moved and stored in the storage part 103. In addition, as the user applies suction through the mouthpiece 102, the inhalable composition stored in the storage part 103 is discharged from the mouthpiece 102 in an aerosol state, thereby gradually consuming the inhalable composition in the storage part 103.

[0043] The tank 200 may be installed inside the housing 101. In this case, the tank 200 is installed in the housing 101 in a replaceable manner. In addition, the tank 200 contains an inhalable composition. The predetermined amount of the composition in the tank 200 may be filled into the storage part 103.

[0044] The user can apply pressure to the rod 300 to fill the composition in the tank 200 into the storage part 103. The rod 300 can constitute a side surface of the housing 101 and be arranged adjacent to the second surface. When the user applies pressure to the rod 300, the rod 300 pushes the bottom surface of the tank 200 upward, so that the injection port 220 of the tank 200 is connected to the storage part 103, and the composition can move from the tank 200 to the storage part 103 through the injection port 220.

[0045] Hereinafter, a direction from a side of the housing 101 where the rod 300 is located to the tank 200 is defined as a first direction, and a direction from a second surface of the housing 101 to the first surface is defined as a second direction.

[0046] On the one hand, a pressure reducing valve 700 may be installed in the storage part 103, and a pressure reducing vent hole 400 may be configured on the first surface of the housing 101. The pressure reducing valve 700 may be linked with the rod 300 through the pressure reducing rod 800 and the pressure reducing rod moving protrusion 320, and the pressure reducing valve 700 may be opened before the rod 300 pushes the can 200 upward, so that the residual gas in the storage part 103 is discharged in advance before the inhalable composition is filled into the storage part 103.

[0047] Will refer to Figures 3 to 5 The pressure reducing valve 700 will be described in detail.

[0048] Reference Figure 2 According to an embodiment, the user of the inhaler 10 can visually confirm the remaining amount of the composition in the storage part 103 through the observation window (not shown) provided in the housing 101. In addition, in the inhaler 10 according to an embodiment, a counter (not shown) and a display window (not shown) can be included, the counter is associated with the up and down movement of the tank 200 when filling the storage part 103 to calculate the number of fillings; the display window is used to display the remaining amount of the composition in the tank 200. When the user applies suction to the suction nozzle 102, the composition stored in the storage part 103 will be sprayed in the form of aerosol. At this time, the suction linkage valve 105 that opens and closes the storage part 103 by suction can be activated, and the piston 106 is used to control the opening and closing operation of the suction linkage valve 105. In addition, the inhaler 10 according to an embodiment may include a cover 500 and a locking device 600 that prevent the tank 200 from separating.

[0049] According to an embodiment of the inhaler 10, the storage part 103 is filled with the inhalable composition in the tank 200. During repeated filling, if there is gas remaining in the storage part 103, it will be difficult to fill the composition in the tank 200 into the storage part 103. Therefore, in the inhaler 10 according to an embodiment, in order to facilitate the filling of the storage part 103, a pressure relief valve 700 linked to the filling rod 300 is applied.

[0050] Reference Figure 3 , the pressure reducing valve 700 of the inhaler 10 according to an embodiment may be separated from one side of the canister 200 and disposed in the storage part 103. The pressure reducing valve 700 may be opened or closed to communicate or block the storage part 103 with the outside.

[0051] The lever 300 may be used to control the opening or closing of the pressure relief valve 700. For example, when the user applies pressure to the lever 300, the lever 300 may be controlled to open the pressure relief valve 700 first and then open the tank 200.

[0052] Thus, the inhaler 10 according to one embodiment employs the pressure reducing valve 700 linked to the rod 300 , thereby exhausting the residual gas in the reservoir 103 and smoothly filling the reservoir 103 with the inhalable composition in the canister 200 .

[0053] The user can apply pressure to the rod 300. At this time, the rod 300 advances toward the tank 200 and reaches the first position, and can reach the second position when the user further applies pressure. When the rod 300 is in the first position, the pressure reducing valve 700 can be opened, and when the rod 300 is in the second position, the pressure reducing valve 700 can be closed and the injection port 220 of the tank 200 can be opened.

[0054] Specifically, the pressure reducing valve 700 is linked to the rod 300 through the pressure reducing rod 800, and can be opened or closed by the lifting and lowering of the pressure reducing rod 800. The pressure reducing rod 800 can be disposed between the rod 300 and the tank 200. One end of the pressure reducing rod 800 can be coupled to the pressure reducing valve 700, and the other end can extend toward the rod 300. As the pressure reducing rod 800 moves in the second direction, the pressure reducing valve 700 can be opened; as the pressure reducing rod 800 returns to the initial position, the pressure reducing valve 700 can be closed.

[0055] The rod 300 may include a support member 310 and a protrusion member 320 .

[0056] The support member 310 may extend toward the tank 200 .

[0057] The protrusion 320 can be rotatably coupled around a rotation axis provided on the support 310. The protrusion 320 may have an end protruding radially from one side of the rotation axis. The end of the protrusion 320 may be arranged to stand upright toward the first surface of the housing 101.

[0058] The other end of the decompression rod 800 may be located between the protrusion 320 and the second surface of the housing 101. In addition, the end of the protrusion 320 may be inclined in a direction away from the tank 200 with the rotation axis as the center.

[0059] When the rod 300 is pressed in the first direction, the support member 310 may restrict the rotation of the protrusion 320. That is, the end of the protrusion 320 may be restricted from rotating from the upright state toward the first surface of the housing 101 to the direction away from the can 200.

[0060] Thus, when pressure is applied to the lever 300, the protrusion 320 also moves in the first direction and reaches the first position, at which time the protrusion 320 contacts the decompression lever 800 and does not rotate, and pushes the decompression lever 800 upward to the second direction.

[0061] Finally, when the rod 300 reaches the first position, the inhalable composition remaining in the storage member 103 can be discharged to the outside.

[0062] On the one hand, when the rod 300 returns to the initial position, the support member 310 can allow the protrusion member 320 to rotate. That is, the end of the protrusion member 320 is not restricted from rotating from the upright state facing the first surface of the housing 101 to the direction facing the tank 200.

[0063] Therefore, when the rod 300 moves in a direction opposite to the first direction at a position exceeding the first position or at the second position, the protrusion 320 does not push the decompression rod 800 upward, but returns to the initial position via the decompression rod 800 .

[0064] Refer again Figure 3 The rod 300 may further include a wedge 330 extending toward the bottom surface of the tank 200 .

[0065] The wedge 330 may include an inclined surface 3301 which is inclined in the first direction to be closer to the bottom surface of the can 200 .

[0066] When the rod 300 is further pressed in the first direction in a state where the inclined surface 3301 is in contact with the bottom surface, the inclined surface 3301 may move the can 200 in the second direction.

[0067] The distance between the inclined surface 3301 of the wedge-shaped member 330 and the bottom surface of the tank 200 may be greater than the distance between the protrusion 320 and the decompression rod 800. Therefore, when the rod 300 moves in the first direction, the protrusion 320 first contacts the other end of the decompression rod 800 before the inclined surface 3301 contacts the bottom surface of the tank 200. That is, before the rod 300 pushes the tank 200 upward to fill the storage member 103, the decompression valve 700 installed in the storage member 103 may be opened first.

[0068] When the can 200 is opened, that is, when the rod 300 reaches the second position and the inclined surface 3301 pushes the can 200 upward in the second direction, the protrusion 320 may be located between the decompression rod 800 and the can 200 .

[0069] Finally, when the rod 300 reaches the second position, the inhalable composition contained in the canister 200 may be filled into the reservoir 103 .

[0070] Refer again Figure 3 The canister 200 of the inhaler 10 according to an embodiment may include a receiving portion 210 and an injection port 220 .

[0071] The housing portion 210 may house an inhalable composition.

[0072] One side of the injection port 220 may be connected to the storage member 103, and the other side may be located in the receiving portion 210. The injection port 220 may be opened or closed relative to the storage member 103. For example, when the rod 300 is in the second position, the injection port 220 may be opened. When the injection port 220 is opened, the inhalable composition contained in the receiving portion 210 may be allowed to move to the storage member 103. On the other hand, when the rod 300 is not in the second position, the injection port 220 may be closed. When the injection port 220 is closed, the path of the inhalable composition moving to the storage member 103 may be blocked, and the filling of the storage member 103 may be stopped.

[0073] The opening and closing operation of the injection port 220 may be controlled according to whether the user applies pressure to the lever 300 .

[0074] As described above, when pressure is applied to the rod 300, the inclined surface 3301 of the wedge 330 can push the bottom surface of the can 200, that is, the bottom surface of the receiving portion 210 upward. At this time, the receiving portion 210 moves in the second direction, but one side of the injection port 220 remains fixed relative to the storage member 103. That is, the position of the injection port 220 in the housing 101 does not change, but the other side of the injection port 220 changes its position in the receiving portion 210 based on the receiving portion 210 rising in the second direction.

[0075] For example, when the other side of the ejection port 220 is deeply pressed into the accommodation portion 210, the ejection port 220 can be opened. Thus, the inhalable composition in the accommodation portion 210 can be moved to the storage member 103 through the ejection port 220. At this time, the inhalable composition can be moved by the pressure difference between the storage member 103 and the accommodation portion 210. That is, when the inhalable composition filled into the storage member 103 is exhausted by the user with aerosol discharge, the pressure in the storage member 103 can be reduced, so when the ejection port 220 is opened, the inhalable composition can be moved from the accommodation portion 210 to the storage member 103. On the contrary, if the storage member 103 is fully filled with the inhalable composition, even if the user applies pressure to the rod 300 to open the ejection port 220, the inhalable composition will not be further moved into the storage member 103.

[0076] Next, we will refer to Figure 4 and Figure 5 The process in which the pressure reducing valve 700 and the canister 200 are sequentially opened and returned to the initial positions when the rod 300 of the inhaler 10 according to an embodiment is operated in two stages is described.

[0077] Figure 4 (a) shows the state of the inhaler 10 when no external force is applied to the rod 300 .

[0078] At this time, if Figure 5 As shown in (a), the pressure reducing valve 700 and the tank 200 are not opened.

[0079] Figure 4 (b) shows the state of the inhaler 10 when a pressure is applied to the rod 300 in a first direction to move the rod 300 to the first position.

[0080] At this time, the support member 310 can limit the rotation of the end of the protrusion 320 in the direction away from the tank 200. At this time, the end of the protrusion 320 contacts the other end of the pressure relief rod 800 in a state of standing upright toward the first surface of the housing 101. The pressure relief rod 800 rises in the second direction under the action of the protrusion 320 and opens the pressure relief valve 700. Figure 5 As shown in (b), when the pressure reducing valve 700 is opened, the composition remaining in the storage part 103 can be discharged to the outside.

[0081] Figure 4 (c) shows that Figure 4 The state of the inhaler 10 when the rod 300 is further pressed in the first direction to move to the second position in the state (b).

[0082] As the rod 300 passes through the first position, the protrusion 320 is disengaged from the end of the pressure relief rod 800, so that the pressure relief rod 800 returns to the initial position. That is, the pressure relief rod 800 is lowered and the pressure relief valve 700 is closed. Figure 5 As shown in (c), when the rod 300 finally reaches the second position, the injection port 220 can be opened as the inclined surface of the wedge 330 raises the receiving portion 210 of the can 200 along the second direction. The inhalable composition can move through the injection port 220 and smoothly fill the storage member 103 from which the residual gas has been discharged.

[0083] Figure 4 (d) shows the state of the inhaler 10 when the rod 300 reaches the first position during the process of returning from the second position to the initial position.

[0084] At this time, if Figure 5 As shown in (d), as the inclined surface 3301 moves in the direction opposite to the first direction, the receiving part 210 descends and closes the injection port 220. In other words, the action of filling the storage part 103 with the inhalable composition can be completed. While the contact between the inclined surface 3301 and the bottom surface of the receiving part 210 is released, the protrusion 320 contacts the other end of the decompression rod 800. At this time, the support member 310 allows the end of the protrusion 320 to rotate toward the tank 200. At this time, the end of the protrusion 320 smoothly passes through the other end of the decompression rod 800 while rotating toward the tank 200, without the need to maintain an upright state. For example, the protrusion 320 can elastically avoid the decompression rod 800. Finally, when moving in the direction opposite to the first direction, the protrusion 320 will not raise the decompression rod 800 in the second direction, so the pressure relief valve 700 remains closed, and the inhalable composition newly filled into the storage part 103 will not be discharged to the outside.

[0085] Figure 4 (e) shows the state of the inhaler 10 when the rod 300 is completely returned to the initial position.

[0086] like Figure 5 As shown in (e), the protrusion 320 of the pressure relief rod 800 can return to the position corresponding to Figure 5 The protrusion 320 of (a) is at the same position. For example, the protrusion 320 may be provided with an elastic member (not shown) that can be compressed in the direction in which the end of the protrusion 320 rotates toward the tank 200. Figure 5 In the step (d) shown in FIG. 1 , the elastic member may be compressed along the direction in which the end of the protrusion 320 rotates toward the tank 200, and if no external force is applied to the protrusion 320, the elastic member may be as shown in FIG. Figure 5As shown in (a) and (e), the protrusion 320 is rotated to the initial position. Therefore, when the rod 300 returns to the initial position after the filling is completed, the protrusion 320 can no longer lift the decompression rod 800, release the elasticity and return to the initial position.

[0087] In the inhaler 10 according to the above-mentioned embodiment, in order to prevent the pressure of the residual gas in the storage part 103 from affecting the inflow of the new composition when the composition is refilled into the storage part 103 using the filling rod 300, a pressure reducing valve 700 linked to the filling rod 300 can be configured to discharge the residual gas in the storage part 103 before filling.

[0088] In the inhaler 10 according to the above embodiment, the filling rod 300 operates in two stages. In the first stage, the pressure reducing valve 700 is opened as a pre-filling state; in the second stage, the pressure reducing valve 700 is closed and filling is performed.
