Description

Technical Field

[0001] This utility model relates to the field of aerosol delivery devices, specifically an aerosol delivery device using an integrated accessory. Background Technology

[0002] Existing aerosol dispensers all have an inhaler that is directly connected to the drug reservoir. When inhaling, the drug in the reservoir is drawn in. Existing aerosol dispensers have many components, such as one-way valves, duckbill valves, and dust caps, all of which require separate fixing parts to connect to the dispenser housing. In particular, the one-way valve is installed on the outside of the housing and needs to be opened frequently. Repeated opening can easily cause it to fall off or shift, resulting in failure of the one-way valve. Therefore, a new aerosol dispenser is needed to simplify the structure and improve the stability of component installation. Utility Model Content

[0003] This invention provides an aerosol delivery device with fewer parts, which solves the problems of existing aerosol delivery devices having many parts, unreliable installation and fixation, and easy detachment of one-way valve plates.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an aerosol delivery device, comprising a drug storage body, one end of which is provided with an aerosol placement interface, the aerosol placement interface having a drug inlet; an upper cover, disposed at the other end of the drug storage body, the end of which is provided with a suction port, and the side of which is provided with a side outlet; further comprising: an integrated inner valve plate, fixedly disposed between the drug storage body and the upper cover, the middle of which is provided with an upward-facing duckbill-shaped air outlet; and a one-way valve. The one-way valve plate is set on the outer wall of the upper cover to form a side outlet. One end of the one-way valve plate is connected to one side of the integrated inner valve plate through a first connecting part. The cap is detachably sleeved on the suction port. One side of the cap is connected to the other side of the integrated inner valve plate through a second connecting part. By making the one-way valve plate, the integrated inner valve plate and the cap into an integrated structure, and pressing and fixing the integrated inner valve plate through the drug storage body and the upper cover, there is no need to set up a separate installation structure to fix the one-way valve plate and the cap. The assembly is very simple, and the one-way valve plate will not fall off during use.

[0005] Preferably, a ring of baffles is provided on the outer side wall of the upper cover around the side outlet, and the one-way valve is embedded in the baffle. The baffle can limit the position of the one-way valve, preventing it from leaving its original position after opening, and also preventing the one-way valve from being sucked into the upper cover.

[0006] Preferably, the bottom of the upper cover of the one-way valve plate is provided with an inwardly offset insertion step wall, and the upper end of the drug storage body is provided with an outwardly offset limiting step. The integrated inner valve plate is mounted and limited on the limiting step. The insertion step wall is located inside the limiting step and is fixed to the limiting step by a rotating buckle. The cooperation between the insertion step wall and the limiting step can achieve the pressing and fixing of the edge of the integrated inner valve plate. At the same time, the rotating buckle can accurately position the relative position between the upper cover and the drug storage body to prevent misalignment.

[0007] Preferably, when the upper cover's insert step wall engages with the limiting step portion, it presses the root of the first connecting portion tightly, effectively using the insert step wall to fix the first connecting portion, preventing the one-way valve plate connected to the first connecting portion from shifting or falling outward.

[0008] Preferably, a limiting groove is provided at the position corresponding to the first connecting part on the insertion step wall. The first connecting part is embedded in the limiting groove, and the limiting groove limits the first connecting part laterally, so that the first connecting part will not move left or right, and also limits the displacement of the one-way valve plate.

[0009] Preferably, the top of the side outlet is provided with a T-shaped slot, and the position where the one-way valve plate is connected to the first connecting part is provided with a T-shaped connecting part that is embedded in the T-shaped slot. The cooperation between the T-shaped slot and the T-shaped connecting part makes the installation of the one-way valve plate more convenient. After installation, the one-way valve plate will not fall down, but will only flip outward along its upper end.

[0010] Preferably, the integrated inner valve plate has multiple reinforcing protrusions on its sidewall, which can improve the rigidity of the integrated inner valve plate and prevent it from undergoing large deformation.

[0011] Preferably, the integrated inner valve plate, cover, first connecting part, second connecting part and one-way valve plate are integrally molded structures of silicone or rubber, which are relatively easy to process and produce. During installation, only the integrated inner valve plate needs to be fixed to achieve positioning.

[0012] Preferably, the sidewall of the inlet is provided with a plurality of air-guiding ribs evenly arranged in the circumferential direction. The air-guiding ribs can guide the inhaled aerosol, thereby increasing the ventilation capacity and allowing the user to inhale the aerosol more easily.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] With a simple structure and few parts, the one-way valve plate, the integrated inner valve plate and the cap are made into a single structure. The integrated inner valve plate is pressed and fixed by the drug storage body and the upper cover. There is no need to set up a separate installation structure to fix the one-way valve plate and the cap. The assembly is very simple. The one-way valve plate will not fall off during use. Moreover, it is easy to disassemble, clean and reassemble without the need for special tools. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figures 1-9 As shown, this utility model addresses the problems of existing aerosol delivery devices having numerous components, unreliable installation and fixation, and easy detachment of the one-way valve plate by providing the following technical solution: An aerosol delivery device includes a drug reservoir 1, one end of which is provided with an aerosol placement interface 2, and the aerosol placement interface 2 has a drug inlet 5; an upper cover 3, which is disposed at the other end of the drug reservoir 1, the end of the upper cover 3 is provided with a suction port 7, and the side of the upper cover 3 is provided with a side outlet 32; and further includes: an integrated inner valve plate 6, fixedly disposed between the drug reservoir 1 and the upper cover 3, the middle of the integrated inner valve plate 6 having an upward-facing opening. The device includes a duckbill-shaped air outlet 61; a one-way valve plate 63, which is located on the outer side wall of the upper cover 3 and has a side outlet 32. One end of the one-way valve plate 63 is connected to one side of the integrated inner valve plate 6 via a first connecting part 64; and a cap 4, which is detachably fitted onto the suction port 7. One side of the cap 4 is connected to the other side of the integrated inner valve plate 6 via a second connecting part 62. By making the one-way valve plate 63, the integrated inner valve plate 6, and the cap 4 into an integrated structure, and by pressing and fixing the integrated inner valve plate 6 with the drug storage body 1 and the upper cover 3, there is no need to set up a separate installation structure to fix the one-way valve plate 63 and the cap 4. The assembly is very simple, and the one-way valve plate 63 will not fall off during use.

[0028] Specifically, the drug reservoir 1 is cylindrical, and the aerosol inlet 2 is used to connect with the medicine bottle. The aerosol inlet 2 and the drug reservoir 1 can be connected by threads. In use, the integrated inner valve plate 6 is placed on the upper end of the drug reservoir 1, and then the one-way valve plate 63 is placed on the side outlet 32. The first connecting part 64 is set through the side outlet 32, and then the upper cover 3 is installed on the drug reservoir 1 to fix the one-way valve plate 63 and the integrated inner valve plate 6. At the same time, the second connecting part 62 and the cap 4 extend outward from the position between the upper cover 3 and the drug reservoir 1. The cap 4 can be closed at any time. Specifically, on the suction port 7, the integrated inner valve plate 6, the cap 4, the first connecting part 64, the second connecting part 62, and the one-way valve plate 63 are integrally molded structures of silicone or rubber, which are relatively easy to process and produce. During installation, it is only necessary to fix the integrated inner valve plate 6 to achieve positioning. The integrally molded components of the integrated inner valve plate 6, the cap 4, the first connecting part 64, the second connecting part 62, and the one-way valve plate 63 are made of medical-grade silicone (Shore hardness 50-60A), which has aging resistance, biocompatibility, and no dissolution when immersed in drugs (such as salbutamol and budesonide).

[0029] The integrated inner valve plate 6 has multiple reinforcing protrusions 66 on its sidewalls, which can improve the rigidity of the integrated inner valve plate 6 and prevent the integrated inner valve plate 6 from undergoing large deformation. For example, four reinforcing protrusions 66 are evenly arranged on the four sides of the integrated inner valve plate 6.

[0030] When using it, such as Figure 7 As shown, this is the exhalation mode. The user exhales with their mouth facing the inhalation port 7. At this time, the duckbill outlet 61 will not open. The exhaled airflow impacts the one-way valve 63, causing the one-way valve 63 to flip outward and open, allowing the airflow to be discharged.

[0031] like Figure 8 As shown, this is the inhalation mode. When inhaling, the medication from the vial connected to the aerosol placement interface 2 can be drawn into the medication storage body 1, and the duckbill air outlet 61 can be opened to draw the medication out from the inhalation port 7. The exhalation mode and the inhalation mode alternate with each other. The user can control the medication administration progress by observing the number of times the one-way valve 63 flips outward.

[0032] In this embodiment, a ring of baffle 31 is provided on the outer side wall of the upper cover 3 around the side drain 32. The one-way valve plate 63 is embedded in the baffle 31. The baffle 31 can limit the position of the one-way valve plate 63, preventing the one-way valve plate 63 from leaving its original position after opening, and also preventing the one-way valve plate 63 from being sucked into the upper cover 3.

[0033] In this embodiment, the bottom of the upper cover 3 of the one-way valve plate 63 is provided with an inwardly offset insertion step wall 35, and the upper end of the drug storage body 1 is provided with an outwardly offset limiting step portion 11. The integrated inner valve plate 6 is mounted and limited on the limiting step portion 11. The insertion step wall 35 is located inside the limiting step portion 11 and is fixed to the limiting step portion 11 by a rotating buckle 34. The cooperation between the insertion step wall 35 and the limiting step portion 11 can achieve the pressing and fixing of the edge of the integrated inner valve plate 6. At the same time, the rotating buckle 34 can accurately position the relative position between the upper cover 3 and the drug storage body 1 to prevent misalignment.

[0034] In this embodiment, when the upper cover 3's insertion step wall 35 engages with the limiting step portion 11, it presses the root of the first connecting portion 64 tightly, effectively using the insertion step wall 35 to fix the first connecting portion 64, preventing the one-way valve plate 63 connected to the first connecting portion 64 from shifting or falling outward.

[0035] In this embodiment, a limiting groove 36 is provided at the position corresponding to the insertion step wall 35 and the first connecting part 64. The first connecting part 64 is embedded in the limiting groove 36, which laterally limits the first connecting part 64, preventing it from moving left or right and also restricting the displacement of the one-way valve plate 63. When the insertion step wall 35 and the limiting step part 11 are engaged by a rotating buckle, the clamping force on the root of the first connecting part 64 can reach 5-8N. Combined with the lateral constraint of the limiting groove, it is ensured that the one-way valve plate will not shift laterally when it flips within a range of ±45°, thus avoiding airflow leakage caused by valve plate misalignment.

[0036] In this embodiment, a T-shaped slot 33 is provided at the top of the side outlet 32, and a T-shaped connecting part 67 is provided at the position where the one-way valve plate 63 connects to the first connecting part 64, which is embedded in the T-shaped slot 33. The cooperation between the T-shaped slot 33 and the T-shaped connecting part 67 makes the installation of the one-way valve plate 63 more convenient. After installation, the one-way valve plate 63 will not fall down, but will only flip outward along its upper end. The one-way valve plate 63 is connected to the integrated inner valve plate 6 through the first connecting part 64, and at the same time, with the fitting of the T-shaped connecting part 67 and the T-shaped slot 33, and the limiting of the enclosure part, a triple fixing structure is formed. Compared with the existing technology that only uses a single buckle for fixing, its resistance to falling off is improved.

[0037] In this embodiment, a plurality of air-guiding ribs 51 are evenly arranged around the side wall of the drug inlet 5. The air-guiding ribs 51 can guide the inhaled aerosol, thereby increasing the ventilation capacity and allowing the user to inhale the drug mist more easily.

[0038] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0039] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
