Atomizing components, container components, and nasal spray device

[0001] Related applications

[0002] This application claims priority to Chinese patent application filed on January 17, 2025, application number 202510075501.4, entitled "Atomizing Component, Container Component and Nasal Spray Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of medical device technology, and in particular to an atomizing component, a container component, and a nasal spray device. Background Technology

[0004] The lateral wall of the nasal cavity is composed of the three turbinates (superior, middle, and inferior) and their corresponding superior, middle, and inferior nasal meatuses. Medially, it is bordered by the nasal septum, and posteriorly, the posterior nasal aperture connects to the pharynx. Traditional nasal sprays deliver targeted drugs to the inferior nasal space, where the epithelium is not optimal for drug absorption. Furthermore, drug clearance is increased due to nasal drops, swallowing, or mucociliary clearance, potentially leading to altered absorption and poor efficacy. Compared to the inferior nasal space, the olfactory epithelium of the superior nasal space has non-motile ciliated cells, is richly vascularized, and has increased permeability, making it an ideal route for rapid drug absorption into the systemic circulation. To ensure targeted delivery and therapeutic efficacy of nasal sprays, it is necessary to rationally control parameters such as the spray rate and particle size distribution of the nasal spray device.

[0005] To deliver more medication deeper into the nasal cavity, common methods include lengthening the nebulizer nozzle or increasing the nebulization force. However, among these methods, an excessively long nozzle may cause discomfort to the patient. Increasing the nebulization force typically involves manually pressing the pump to spray the medication while simultaneously adding an additional mouth-blowing technique. This utilizes the airflow from the mouth to assist in increasing the driving force, requiring coordination between pressing and mouth-blowing, and demanding a high degree of hand-mouth coordination from the operator.

[0069] The effects of the invention

[0070] In this embodiment, when the blocking member is in the locked position, the fluid channel is blocked, and the liquid in the container assembly cannot be sprayed. When air is blown into the nozzle, the airflow pushes the blocking member to the open position. Driven by the power source inside the container assembly, the liquid is sprayed through the fluid channel towards the nose socket. The airflow blown into the nozzle can also drive the liquid to spray. After being sprayed, the liquid enters the nasal cavity through the nose socket. No pressing operation is required; simply blowing air can open the fluid channel and assist in liquid spraying, reducing the operational difficulty of the nasal spray device.

[0071] Moreover, the airflow blown in through the nozzle can both assist in accelerating the liquid spray and in atomizing the liquid. This dual-power drive mode, which utilizes both a power source and airflow, can improve the spray rate and spray particle size distribution, thereby enhancing the therapeutic effect.

[0094] Example 1

[0095] The nebulizer 100 provided in this embodiment is used in conjunction with the container assembly 200, as shown in FIG11. The nebulizer 100 and the container assembly 200, when assembled, form a nasal spray device 300. The container assembly 200 includes a power source and a container; unrestrictedly, the drug is stored in a liquid state within the container. When the nasal spray device 300 is triggered, the power source drives the liquid to spray from the container towards the nebulizer 100, and ultimately, the liquid enters the nasal cavity in an atomized state, achieving nasal drug delivery.

[0096] The atomizing component 100 of the present application embodiment is described in detail below with reference to Figures 1 to 8 and Figures 11 to 17.

[0097] Referring to Figures 1 to 3, the atomizing assembly 100 includes a mouthpiece structure 110, a nose support structure 120, and a blocking member 130 (shown in Figure 3). The mouthpiece structure 110 has a mouthpiece 112, and the nose support structure 120 has a nose opening 1211. During use, the operator blows air into the nose support structure 120 using the mouthpiece 112, and the atomized droplets are sprayed into the nasal cavity through the nose opening 1211.

[0098] The nose support structure 120 also includes a fluid channel 124. To allow liquid to be sprayed, the nose port 1211 is at least in communication with the fluid channel 124, so that liquid in the container assembly 200 can be sprayed onto the nose port 1211 via the fluid channel 124. The blocking member 130 has at least a locked position and an open position relative to the nose support structure 120; the locked position is used to close the fluid channel 124, and the open position is used to open the fluid channel 124; when the atomizing assembly 100 is connected to the container assembly 200 containing liquid, the blocking member 130 is in the locked position, and the liquid tends to flow towards the fluid channel 124 under the drive of the power source of the container assembly 200; when air is blown onto the nozzle 112, the airflow generated by the blowing pushes the blocking member 130 from the locked position to the open position, so that the liquid is sprayed onto the nose port 1211 via the fluid channel 124 under the drive of the power source.

[0099] The nasal support structure 120 also includes an auxiliary channel 123, through which the airflow blown in through the mouthpiece 112 can also provide driving force for the liquid spray. The airflow blown in through the mouthpiece 112 can both assist in accelerating the liquid spray and assist in liquid atomization. This dual-power drive mode, which utilizes both a power source and airflow, can improve the spray rate and spray particle size distribution, thereby enhancing the therapeutic effect.

[0100] When the blocking member 130 is in the locked position, the fluid channel 124 is blocked, and the liquid in the container assembly 200 cannot be sprayed. However, under the drive of the power source, the fluid has a tendency to spray and is in a state of waiting to be sprayed. When air is blown into the nozzle 112, the airflow pushes the blocking member 130 to the open position. Under the drive of the power source inside the container assembly 200, the liquid is sprayed through the fluid channel 124 towards the nose port 1211. The process of triggering the spray does not require pressing; simply blowing air can open the fluid channel 124 and assist in the liquid spraying, reducing the operational difficulty of the nasal spray device 300.

[0101] For example, the nebulizer assembly 100 and the container assembly 200 are detachable structures; in other words, the container assembly 200 is replaceable. Thus, the nebulizer assembly 100 is reusable, and one nebulizer assembly 100 can be matched with different dosage container assemblies 200 to deliver different doses of medication. Alternatively, different container assemblies 200 with the same dosage can be replaced. To enable the nebulizer assembly 100 to be reusable, the blocking member 130 is switchable between a locked position and an open position relative to the nose support structure 120, wherein the nebulizer assembly 100 remains in the locked position when there is no airflow.

[0102] Without limitation, container component 200 can be a single-use part.

[0103] In some alternative embodiments, when the atomizing component 100 is connected to the container component 200, the atomizing component 100 triggers the valve structure of the container component 200 to be in an open state, so that the liquid tends to flow towards the fluid channel 124 under the drive of the power source of the container component 200.

[0104] When the atomizing component 100 is not connected to the container component 200, the valve structure of the container component 200 is in the closed state, thus avoiding unwanted liquid spraying due to accidental triggering. When the atomizing component 100 is connected to the container component 200, the atomizing component 100 triggers the valve structure to switch to the open state, and at least some liquid will flow upward from inside the container component 200. However, due to the obstruction of the blocking member 130, the liquid will not continue to spray and will remain in a ready-to-spray state. When the operator is ready (for example, aligning the nose cup 1211 with the nasal cavity and the mouthpiece 112 with the oral cavity), blowing air through the mouthpiece 112 will finally achieve liquid spraying. Therefore, this embodiment of the application utilizes the connection between the atomizing component 100 and the container component 200 to achieve both connection and fixation between the atomizing component 100 and the container component 200, and also opens the valve structure, putting the liquid in a ready-to-spray state, achieving two goals at once and making the operation more efficient and convenient.

[0105] Referring to Figures 4 to 6, in some optional embodiments, the nose support structure 120 includes a nose support body 121 and a push post 122. The nose support body 121 has a nose support opening 1211, a fluid channel 124, and an auxiliary channel 123. The push post 122 is connected to the nose support body 121. When the atomizing assembly 100 is connected to the container assembly 200, the push post 122 pushes the valve structure to move so that the valve structure is in the open state.

[0106] For example, the atomizing component 100 is assembled with the container component 200 from top to bottom. During the assembly process, the pushing column 122 gradually approaches until it contacts the valve structure, thereby pushing the valve structure to move and switching the valve structure from a closed state to an open state. That is, the valve structure can be opened by using the connection operation between the atomizing component 100 and the container component 200, which is simple to operate.

[0107] The push post 122 and the nose support body 121 can be integral components, which can be formed by one-piece molding, thus simplifying the nose support structure 120. However, it is not limited to this. For example, the push post 122 and the nose support body 121 can also be separate structures, and the push post 122 and the nose support body 121 can be connected by snap-fit, adhesive or other methods.

[0108] In some alternative embodiments, as shown in FIG4, the push post 122 is located at the bottom of the nose support body 121, and the nose support opening 1211 forms the outlet of the fluid channel 124. The inlet 1243 of the fluid channel 124 surrounds the outer periphery of the push post 122. The push post 122 is located below the fluid channel 124. In order to ensure that the liquid enters the fluid channel 124 smoothly and does not affect the triggering function of the valve structure, the inlet 1243 of the fluid channel 124 is designed as a "flow-around opening" as shown in FIG4. The number of inlets 1243 of the fluid channel 124 can be one, two or more. When there are multiple inlets 1243 of the fluid channel 124, the multiple inlets 1243 are evenly distributed around the outside of the push post 122. FIG4 exemplarily shows the inlets 1243 of two fluid channels 124.

[0109] As can be seen from the implementation shown in Figures 4 to 6, the push post 122 is arranged protruding downwards from the bottom of the nose support body 121. The fluid channel 124 is approximately located at the center of the nose support structure 120, and the push post 122 and the fluid channel 124 are approximately coaxially distributed. As shown in Figures 13 and 15, the valve channel 241 (further mentioned below) for liquid passage in the valve structure is approximately coaxially distributed with the fluid channel 124, where "axis" can refer to the center of the corresponding channel. The valve channel 241 is located approximately at the center of the container assembly 200.

[0110] In some alternative embodiments, as shown in FIG8, the blocking member 130 includes a through hole 1311. When the blocking member 130 is in the open position as shown in FIG15 and FIG16, the through hole 1311 communicates with the fluid channel 124 so that liquid enters the fluid channel 124 through the through hole 1311. When the blocking member 130 is in the locked position as shown in FIG12 and FIG13, the through hole 1311 is offset from the fluid channel 124 so as to prevent liquid from entering the fluid channel 124.

[0111] For example, in order to ensure smooth liquid flow, the inner diameter of the through hole 1311 is approximately equal to the inner diameter of the fluid channel 124, and when the blocking member 130 is in the open position, the through hole 1311 and the fluid channel 124 are approximately coaxial.

[0112] In some alternative embodiments, as shown in FIG6, the nose support structure 120 further has a first receiving cavity 126, and a blocking member 130 is movably located within the first receiving cavity 126; the first receiving cavity 126 divides the fluid channel 124 into a first chamber 1241 and a second chamber 1242, the first chamber 1241 being in communication with the nose support opening 1211; when the blocking member 130 is in the locked position, liquid at least partially enters the second chamber 1242 under the driving action of the power source of the container assembly 200, and the blocking member 130 prevents liquid from entering the first chamber 1241; when the blocking member 130 is moved to the open position, liquid in the second chamber 1242 is sprayed sequentially through the hole 1311 and the first chamber 1241 toward the nose support opening 1211.

[0113] For example, as shown in FIG3, the first receiving cavity 126 may be connected to the mouthpiece 112 so that the airflow blown in by the mouthpiece 112 enters the first receiving cavity 126 and pushes the blocking member 130 to move.

[0114] In some alternative embodiments, as shown in FIG3, the atomizing assembly 100 further includes: a first elastic member 140, one end of the first elastic member 140 being fixed relative to the nose support structure 120, and the other end of the first elastic member 140 being connected to the blocking member 130 to provide elastic force for keeping the blocking member 130 in the locked position.

[0115] Under the elastic action of the first elastic member 140, the blocking member 130 remains in the locked position. When the driving force of the airflow blown in through the mouthpiece 112 is greater than the elastic force of the first elastic member 140, the blocking member 130 can switch from the locked position to the open position. After the blowing stops, the blocking member 130 returns to the locked position under the action of the first elastic member 140, thus realizing the switching of the blocking member 130 between the locked position and the open position.

[0116] The first elastic element 140 is a spring or a sheet, but is not limited to these.

[0117] Figures 3 and 6 exemplarily show that the first elastic member 140 is a compression spring, the left side of the first receiving cavity 126 is closed, and its right side is open. The first elastic member 140 is located between the left side wall of the first receiving cavity 126 and the left end of the blocking member 130. The right opening of the first receiving cavity 126 is connected to the mouthpiece 112.

[0118] In some alternative embodiments, as shown in Figures 13 and 14, when the blocking member 130 is in the locked position, the blocking member 130 also closes the auxiliary channel 123; as shown in Figures 16 and 17, when the blocking member 130 is in the open position, the blocking member 130 also opens the auxiliary channel 123. When the blocking member 130 is in the locked position, it can close both the fluid channel 124 and the auxiliary channel 123, thus preventing gas from entering the atomizing assembly 100 when not in use and reducing contamination of the atomizing assembly 100.

[0119] To further improve the hygiene of the atomizing component 100, a cap can be added to the outside of the atomizing component 100, the cap at least covering the nose port 1211.

[0120] In some alternative embodiments, as shown in FIG6, the cavity wall of the first receiving cavity 126 is provided with a limiting groove 127. The limiting groove 127 includes a first groove wall 1271 and a second groove wall 1272 arranged side by side along the moving direction of the blocking member 130. The entrance of the auxiliary channel 123 is at least partially located between the first groove wall 1271 and the second groove wall 1272. The first groove wall 1271 and the second groove wall 1272 can limit the distance that the blocking member 130 moves within the first receiving cavity 126.

[0121] As shown in Figure 8, the blocking member 130 includes a blocking body 131 and a limiting protrusion 132. The blocking body 131 is movably disposed in the first receiving cavity 126 and has the aforementioned through hole 1311. The limiting protrusion 132 is located on the blocking body 131 and moves synchronously in the limiting groove 127 as the blocking body 131 moves. When the blocking member 130 is in the locked position, as shown in Figure 14, the limiting protrusion 132 abuts against the first groove wall 1271, and the blocking body 131 simultaneously closes the fluid channel 124 and the auxiliary channel 123. When the blocking member 130 is in the open position, as shown in Figure 17, the limiting protrusion 132 abuts against the second groove wall 1272, the through hole 1311 communicates with the fluid channel 124, and the auxiliary channel 123 communicates with the mouthpiece 112.

[0122] Referring to Figure 17, the inlet of the auxiliary channel 123 is located above the first receiving cavity 126, and both the auxiliary channel 123 and the limiting groove 127 are connected to the first receiving cavity 126. The auxiliary channel 123 can have one, two, three, or more inlets. When the blocking member 130 is in the locked position, the solid portion of the blocking member 130 simultaneously blocks both the fluid channel 124 and the auxiliary channel 123, preventing external fluid from entering the auxiliary channel 123.

[0123] In some alternative embodiments, as shown in Figures 5 and 6, an auxiliary channel 123 surrounds the nose port 1211. The airflow from the auxiliary channel 123 can assist the droplets ejected from the nose port 1211 to be further atomized into smaller particles, while accelerating the movement of the aerosol, ensuring the atomization and dispersion effect of the liquid medicine and the spray rate, so that more spray is delivered to the target site.

[0124] Referring to Figure 3, the atomizing component 100 is inclined from top to bottom at the fluid outlet (including the nose port 1211 and the end face of the auxiliary channel 123), which can better match the nasal cavity and deliver more spray to the target area.

[0125] In some alternative embodiments, as shown in Figures 3, 4 and 6, the bottom of the nose support structure 120 is provided with a fixing groove 125, which can be inserted and engaged with the fixing protrusion of the container assembly 200 to improve the reliability of the connection between the nose support structure 120 and the container assembly 200.

[0126] In embodiments not shown in this application, a fixing protrusion may also be disposed on the nose support structure 120, and the fixing protrusion may be inserted into the fixing groove 125 of the container assembly 200.

[0127] In some alternative embodiments, referring to FIG13, the atomizing assembly 100 further includes a seal 400 located within the fixing groove 125 to seal the nose support structure 120 to the container assembly 200. After the atomizing assembly 100 is connected to the container assembly 200, the seal 400 is located between the top wall of the fixing groove 125 and the top wall of the fixing protrusion to prevent liquid in the container assembly 200 from leaking through the connection between the nose support structure 120 and the container assembly 200.

[0128] Without limitation, the seal 400 can be a component independent of the nose support structure 120. When assembling the atomizing assembly 100 and the container assembly 200, the seal 400 is placed in the fixing groove 125, and then the atomizing assembly 100 and the container assembly 200 are assembled.

[0129] The seal 400 can be a flexible sealing gasket, but is not limited to this.

[0130] In some alternative embodiments, the atomizing assembly 100 further includes an atomizing chip 150, which is mounted on the nose support structure 120 and located in the liquid spray path to atomize the sprayed liquid.

[0131] The liquid medicine is delivered to the atomizing chip 150 through the fluid channel 124 to complete the atomization process.

[0132] As shown in Figure 6, the atomizing chip 150 is located in the fixed chamber 1244 inside the nose support structure 120. The fixed chamber 1244 is located in the fluid channel 124 and between the nose support opening 1211 and the first receiving cavity 126. There is no relative movement or rotation between the atomizing chip 150 and the nose support structure 120.

[0133] In some optional embodiments, as shown in FIG7, the mouth support structure 110 further includes: a mouth support body 111, which is connected to the container assembly 200 and has a second receiving cavity 113 for receiving the nose support structure 120 and a spray port 1111 communicating with the nose support port 1211; the mouthpiece 112 is connected to the mouth support body 111; when the mouth support body 111 and the container assembly 200 are assembled in place, the atomizing component 100 pushes the valve structure of the container assembly 200 to move to the open state.

[0134] The nozzle 1111 is used, for example, the nasal inlet 1211, to ensure that the droplets are smoothly sprayed into the nasal cavity.

[0135] The mouthpiece body 111 and the mouthpiece 112 can be integral components, and the mouthpiece structure 110 can be formed by one-piece molding.

[0136] For example, the mouth support structure 110 and the nose support structure 120 may be detachable structures.

[0137] The second receiving cavity 113 is connected to the mouthpiece 112 and the jet nozzle 1111 respectively. After the nose support structure 120 is installed in the second receiving cavity 113, the opening of the first receiving cavity 126 is connected to the mouthpiece 112, and the nose support opening 1211 is aligned with the jet nozzle 1111.

[0138] The mouth support structure 110 serves as both a carrier for mounting and fixing the nose support structure 120 and a means for the mouthpiece 112 to blow air, making it a multi-purpose component.

[0139] In some alternative embodiments, the bearing body 111 is threaded; Figure 7 exemplarily shows that the thread of the bearing body 111 is an internal thread 115. The bearing body 111 is threadedly assembled with the container assembly 200. The bearing structure 110 is also used to connect the container assembly 200, realizing the assembly of the two. The threaded connection method is simple and reliable.

[0140] In other embodiments, the spout body 111 may also be assembled with the container assembly 200 by other means (such as snap-fit ​​connection, screw connection).

[0141] In some alternative embodiments, as shown in FIG7, the mouth support body 111 further includes a nose support fixing plate 114 connected to the inner wall of the second receiving cavity 113. The nose support fixing plate 114 has a mounting hole 1141, as shown in FIG3, and the nose support structure 120 passes through the mounting hole 1141.

[0142] The nose support structure 120 can be fixed by using the nose support fixing plate 114 to ensure the reliability of the connection between the nose support structure 120 and the mouth support structure 110.

[0143] Based on the foregoing description, the nose support fixing plate 114 is located at the upper part of the nose support structure 120, and the fixing groove 125 is located at the bottom of the nose support structure 120. When the atomizing component 100 is connected to the container component 200, the nose support fixing plate 114 at least prevents the nose support structure 120 from moving upward, and the mating part of the fixing groove 125 and the container component 200 at least prevents the nose support structure 120 from moving downward, thus ensuring the installation and fixation of the nose support structure 120.

[0144] In some alternative embodiments, as shown in Figures 3 and 6, the outer diameter of the nose support structure 120 gradually increases from the nose support fixing plate 114 toward the container assembly 200. After the nose support structure 120 is inserted into the mounting hole 1141 of the nose support fixing plate 114, its outer diameter gradually increases downwards, preventing it from completely passing through the mounting hole 1141. Thus, the nose support fixing plate 114 fixes the nose support structure 120 in place. This method eliminates the need for additional fasteners to secure the two components, allowing for the installation and removal of the nose support structure 120 and the mouth support structure 110 without tools, making it simple and convenient.

[0145] In some alternative embodiments, as shown in FIG7, the mouthpiece 112 includes a first segment 1121 and a second segment 1122. One end of the first segment 1121 forms the inlet of the mouthpiece 112, and the other end of the first segment 1121 is connected to the second segment 1122. As shown in FIG3, the atomizing assembly 100 also includes a connecting tube 160, which is located inside the second segment 1122 and connects to the first segment 1121 and the first receiving cavity 126 respectively. The connecting tube 160 can better connect the first receiving cavity 126 and the first segment 1121, ensuring that the airflow has sufficient speed to push the blocking member 130 and drive atomization.

[0146] In some alternative embodiments, the cross-section of the connecting tube 160 gradually decreases toward the nose support structure 120.

[0147] For example, the connecting pipe 160 is a cylindrical hollow pipe with a variable diameter. The end with a larger diameter is fixed to the second section 1122, and the end with a smaller diameter is built into the first receiving cavity 126 of the nose support structure 120. When the connecting pipe 160 is assembled with the nose support structure 120 and the mouth support structure 110, the surfaces are completely fitted without gaps and there is no relative movement or rotation.

[0148] As shown in Figure 8, one end of the blocking member 130 has a first groove 134. As shown in Figure 6, the left side of the first receiving cavity 126 is provided with a second groove 1261 opposite to the first groove 134. The two ends of the first elastic member 140 are respectively located in the first groove 134 and the second groove 1261 to improve the reliability of the assembly of the first elastic member 140.

[0149] Referring to Figure 8, the other end of the blocking member 130 has an arc-shaped end face 133. The through hole 1311 is located approximately in the middle of the blocking member 130. The limiting protrusion 132 is located between the through hole 1311 and the arc-shaped end face 133. This structure allows the arc-shaped end face 133 to fit against the inner wall of the bearing structure 110, but it will not cause the connecting pipe 160 to be pushed due to the elastic force of the first elastic member 140 when it is reset, which is beneficial to protecting the reliability of the installation of the connecting pipe 160.

[0150] When the user holds the mouthpiece 112 in their mouth and places the nose support 1211 inside the nasal cavity, the airflow passes sequentially through the first section 1121 of the mouthpiece 112 and the connecting tube 160 when blowing forcefully. As the cross-section of the airflow channel gradually decreases, the airflow velocity gradually increases. A portion of the high-speed airflow pushes the blocking member 130 to the left, compressing the first elastic member 140. During the movement of the blocking member 130, the through hole 1311 gradually connects with the fluid channel 124 of the nose support structure 120. Under the pressure inside the medicine bottle, the liquid in the second chamber 1242 rapidly moves upward to the first chamber 1241 and is atomized by the atomizing chip 150 before entering the nasal cavity.

[0151] In addition, another portion of the gas moves upward through the auxiliary channel 123 and overflows from both sides of the nasal inlet 1211. The auxiliary airflow can continue to disperse the atomized droplets on the one hand, and accelerate the droplets on the other hand, increasing the speed at which the atomized aerosol enters the nasal cavity and is delivered to a deeper part of the nasal cavity.

[0152] Example 2

[0153] The container component 200 of this embodiment will be described in further detail below with reference to Figures 9 and 10.

[0154] The container assembly 200 of this application embodiment is used in connection with the atomizing assembly 100 described in Embodiment 1.

[0155] The container component 200 in this embodiment includes all the technical features of the container component 200 in embodiment 1, and will not be described again.

[0156] As shown in Figure 10, the container assembly 200 includes a tank 210 and a bag 220. The bag 220 is located inside the tank 210, and the inner cavity of the bag 220 is used to contain liquid. There is a space 201 between the bag 220 and the tank 210, and the space 201 contains a power source.

[0157] Without limitation, the power source can be compressed gas. Under the pressure of the power source, the liquid inside the bag 220 can enter the fluid channel 124. The power source for liquid atomization mainly comes from the compressed gas between the bag 220 and the tank 210, and the atomization drive mainly comes from the power of the air blown by the nozzle 112.

[0158] The container assembly 200 may also include a valve seat 230, which is connected to the tank 210 and the bag 220 respectively to seal the space 201.

[0159] The container assembly 200 may also include a valve structure for opening or closing the bag 220. When the valve structure is in the open state, the power source compresses the bag 220 to provide driving force for the jetting of liquid.

[0160] In some alternative embodiments, continuing to refer to FIG10, the valve structure includes: a valve body 240, a one-way valve 250, and a second elastic member 260. The valve body 240 has a valve channel 241 communicating with the inner cavity of the bag body 220. The one-way valve 250 is movably installed in the valve channel 241. One end of the second elastic member 260 is fixed relative to the valve body 240, and the other end is connected to the one-way valve 250. The second elastic member 260 is used to hold the one-way valve 250 in the position of closing the valve channel 241, so that the valve structure is in the closed state. When the atomizing assembly 100 is connected to the container assembly 200, the atomizing assembly 100 pushes the one-way valve 250 against the elastic force of the second elastic member 260, so that the one-way valve 250 opens the valve channel 241, and the valve structure is in the open state.

[0161] Under the elastic action of the second elastic element 260, the one-way valve 250 remains in the closed state. When the atomizing assembly 100 is installed in place, the atomizing assembly 100 pushes the one-way valve 250 to overcome the elastic force of the second elastic element 260, and the one-way valve 250 can switch from the closed state to the open state.

[0162] The second elastic element 260 is a compression spring or a sheet, but is not limited to this.

[0163] In some optional embodiments, as shown in FIG10, the valve passage 241 includes: an upper passage 2411, a lower passage 2413, and a transition passage 2412. The two ends of the transition passage 2412 are respectively connected to the upper passage 2411 and the lower passage 2413. The inner diameter of the lower passage 2413 is larger than the inner diameter of the upper passage 2411, and the bottom inner diameter of the transition passage 2412 is larger than the top inner diameter of the transition passage 2412. The one-way valve 250 includes: a base 251 and a valve connected to the base. The driving part 252 on 251 has a maximum outer diameter that is greater than the minimum inner diameter of the transition channel 2412, and an outer diameter that is smaller than the inner diameter of the upper channel 2411, and is located inside the upper channel 2411. When the valve structure is in the closed state, the base 251 fits against the inner wall of the transition channel 2412 to close the valve channel 241. When the valve structure is in the open state, there is a gap between the base 251 and the inner wall of the transition channel 2412 to open the valve channel 241.

[0164] Both "inner diameter" and "outer diameter" can be diameters.

[0165] For example, the drive part 252 and the base part 251 are integral structures, and the one-way valve 250 can be formed by integral molding.

[0166] When the atomizing assembly 100 is connected to the container assembly 200, the push post 122 of the atomizing assembly 100 docks with the drive part 252 of the one-way valve 250, and the push post 122 pushes the drive part 252 to move downward, opening the valve channel 241.

[0167] The maximum outer diameter of the base 251 is larger than the minimum inner diameter of the transition channel 2412. The base 251 cannot pass through the minimum inner diameter of the transition channel 2412, thus limiting the movement of the check valve 250. When the check valve 250 is in contact with the inner wall of the transition channel 2412 due to the limiting effect of the transition channel 2412, the liquid below cannot flow upwards. In other words, the check valve 250 cannot move into the upper channel 2411, and at this time, the valve channel 241 is closed. Because the inner diameter of the lower channel 2413 is larger, when the pusher 122 pushes the check valve 250 downwards, the check valve 250 can move into the lower channel 2413, creating a gap between the check valve 250 and the inner wall of the valve channel 241, thus opening the valve channel 241.

[0168] The second elastic element 260 is compressed or reset as the one-way valve 250 moves up and down.

[0169] As can be seen from the implementation shown in Figure 10, the outer diameter of the base 251 gradually increases from top to bottom, and the inner diameter of the transition channel 2412 gradually increases from top to bottom. The outer diameter of the base 251 at approximately the middle position is greater than or equal to the inner diameter of the upper channel 2411, so the one-way valve 250 cannot move into the upper channel 2411.

[0170] In some alternative embodiments, the valve structure shown in FIG10 further includes: a valve core 280, which is at least partially located below and connected to the valve body 240, and has a flow channel 281 that connects the valve channel 241 and the inner cavity of the bag body 220 respectively.

[0171] Valve passage 241 is used for liquid transport. Valve body 240 and valve core 280 are placed inside bag body 220. Valve body 240 and valve core 280 are sealed together without relative movement or rotation. One end of second elastic element 260 is fixed to the top surface of valve core 280, and the other end of second elastic element 260 is fixed to the lower end face of check valve 250. It can be understood that, in addition to being fixed to the top of valve core 280, one end of second elastic element 260 can also be fixed in other ways. For example, a boss can extend inward from the inner wall of valve passage 240 of valve body 240, and one end of second elastic element 260 can be fixed to this boss.

[0172] For example, the valve body 240 protrudes at least partially from the canister 210, and the top of the valve body 240 can serve as a fixing protrusion that is inserted into the fixing groove 125 of the aforementioned atomizing assembly 100.

[0173] The valve core 280 is located below the valve body 240. The liquid in the bag 220 first enters the flow channel 281, and then enters the valve passage 241 through the flow channel 281. The valve core 280 extends the valve passage 241, making it easier for the liquid in the bag 220 to enter the valve passage 241.

[0174] Referring again to Figure 10, in some alternative embodiments, one end of the second elastic member 260 is connected to the top of the valve core 280, and the other end is connected to the bottom of the one-way valve 250. In addition to providing the flow channel 281, the valve core 280 can also serve as a carrier for fixing the second elastic member 260.

[0175] In some alternative embodiments, the container assembly 200 further includes a top cover 270 mounted on a valve seat 230, the top cover 270 or the valve seat 230 having threads for connecting the atomizing assembly 100.

[0176] In the implementation shown in Figures 9 and 10, the thread is formed on the outer periphery of the upper cover 270, i.e., the external thread 271. The upper cover 270 is located above the valve seat 230 and is coaxially sealed with the valve seat 230 without relative rotation. The external thread 271 on the cylindrical surface of the outer periphery of the upper cover 270 is mainly used to mate with the internal thread 115 at the lower end of the bearing structure 110 of the atomizing component 100.

[0177] In some alternative embodiments, as shown in Figures 9 and 10, the container assembly 200 further includes a sealing element 290 that is removably covered over the outlet of the valve structure, through which liquid is ejected.

[0178] A sealing element 290 covers the top of the valve body 240 and can be made of flexible plastic. When using the container assembly 200, the sealing element 290 can be torn off or pierced. The sealing element 290 at the top of the valve body 240 can also be designed as a threaded medicine bottle cap or a plastic bottle cap, which can be opened or removed by simply rotating or pulling it off during use.

[0179] Example 3

[0180] Example 3 provides a nasal spray device 300, which includes: the atomizing component 100 described in Example 1, and the container component 200 described in Example 2.

[0181] The general assembly process of the atomizing component 100 and the container component 200 includes: first, removing the sealing piece 290 at the top of the container component 200; placing a flexible sealing gasket (a specific form of the sealing piece 400) in the fixing groove 125 at the lower end of the atomizing component 100; and then fitting it into the fixing groove 125 at the top of the upper cover 270. Next, by rotating downwards, the push post 122 at the bottom of the nose support structure 120 pushes the one-way valve 250 inside the container component 200 downwards, compressing the second elastic element 260 at the lower end. At this time, the valve channels 241 at both ends of the one-way valve 250 are connected. Simultaneously, the internal thread 115 at the lower end of the mouth support structure 110 matches the thread on the outer side of the upper cover 270, completing the sealing and fixing of the two components during rotation.

[0182] The bag valve type container assembly 200 is designed as a replaceable component. When the liquid medicine in the container assembly 200 is used up, the two components can be separated by rotating the atomizing component 100, and then a new medicine bottle can be replaced. After reassembly, it can be used again.

[0183] The general usage process of the nasal spray device 300 includes: initial state, atomization process and reset process.

[0184] As shown in Figures 12 and 13, in the initial state, the first elastic member 140 is in a compressed or free state, and the limiting protrusion 132 of the blocking member 130 abuts against the inner wall surface of the nose support structure 120. Under the pressure of the compressed gas between the canister 210 and the bag 220, the liquid in the bag 220 flows sequentially through the inlet of the flow channel 281, the valve channel 241, and the fluid channel 124, and enters the second chamber 1242 of the fluid channel 124. At this time, the blocking member 130 completely separates the first chamber 1241 and the second chamber 1242, preventing the liquid from entering the upper part of the atomizing assembly 100.

[0185] Referring to Figures 15 and 16, when the user holds the mouthpiece 112 in their mouth and places the nose support 1211 inside the nasal cavity, the airflow passes sequentially through the mouthpiece 112 and the connecting tube 160 when forcefully blowing air. Because the cross-section of this airflow channel gradually decreases, the airflow velocity gradually increases. A portion of the high-speed airflow pushes the blocking member 130 to the left, compressing the first elastic member 140. During the movement of the blocking member 130, the through hole 1311 gradually connects with the first chamber 1241 and the second chamber 1242 of the nose support structure 120. Under the pressure within the container assembly 200, the liquid in the second chamber 1242 rapidly rises, is atomized by the atomizing chip 150, and enters the nasal cavity.

[0186] In addition, another portion of the gas enters the auxiliary channel 123 through the first receiving cavity 126. After the airflow rises, it overflows from both sides of the nasal inlet 1211. The auxiliary airflow can both continue to disperse the atomized droplets and accelerate them, increasing the speed at which the atomized aerosol enters the nasal cavity and is delivered deeper into the nasal cavity. This process is the atomization process.

[0187] When air is stopped being blown into the mouthpiece 112, the compressed first elastic element 140 releases its elastic force, pushing the blocking element 130 back to its original position until the outer edge arc surface of the blocking element 130 is completely in contact with the lower outer arc surface of the nose support structure 120. During this resetting process, the through hole 1311 gradually moves to the right, and the solid part of the blocking element 130 gradually separates the first chamber 1241 and the second chamber 1242 of the nose support structure 120, gradually disconnecting the fluid channel 124. Once the fluid channel 124 is completely disconnected, atomization stops. This process is the resetting process.

[0188] Without conflict, different embodiments or different technical features of this application may be arbitrarily combined to form new embodiments.

[0189] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this application. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
