Description
Technical Field

Background
The outer side of the nasal cavity is an outer side wall, which consists of an upper nasal concha, a middle nasal concha, a lower nasal concha, an upper nasal septum, a middle nasal septum and a rear nasal Kong Tongyan. Traditional nasal devices target drug delivery to the lower nasal space where the epithelium is not optimal for drug absorption and the likelihood of drug clearance increases due to nasal drops, swallowing, or mucociliary clearance, potentially leading to altered absorption and poor efficacy. Compared with the lower nasal space, the olfactory epithelium of the upper nasal space has non-motile cilia cells, is rich in blood vessels and has increased permeability, so that the olfactory epithelium becomes an ideal way for the medicine to be rapidly absorbed into the systemic circulation. In order to ensure the targeted delivery and treatment effect of the liquid medicine spray through the nasal cavity, the parameters such as the spraying rate and the spraying granularity distribution of the nasal spray device are required to be reasonably controlled.
To achieve more drug delivery deep in the nasal cavity, common approaches include lengthening the nebulizer head or increasing the nebulizing driving force, etc. However, in the above method, too long a nebulizer head may cause discomfort when the patient uses the nebulizer head. The atomizing driving force is increased, the pumping assembly is driven to spray the medicine by manual pressing, an additional mouth blowing mode is added, the driving force is increased by the aid of air flow of mouth blowing, the combination of pressing and mouth blowing is needed, and the requirement on hand-mouth coordination of an operator is high.

Example 1
The atomizing assembly 100 provided in the embodiments of the present disclosure is configured to cooperate with the container assembly 200, as shown in fig. 11, such that the atomizing assembly 100 is assembled with the container assembly 200 to form a nasal spray device 300. The container assembly 200 includes a power source and a container, without limitation, within which the medicament is stored in a liquid state. After the nasal spray device 300 is triggered, the power source drives the liquid to spray from the container to the atomizing assembly 100 and finally enter the nasal cavity in an atomized state to achieve nasal administration.
An atomizing assembly 100 according to an embodiment of the present disclosure is described in detail below with reference to fig. 1-8, and in conjunction with fig. 11-17.
Referring to fig. 1-3, the atomizing assembly 100 includes a mouthpiece structure 110, a nose piece structure 120, and a barrier 130 (shown in fig. 3), wherein the mouthpiece structure 110 has a mouthpiece 112, and the nose piece structure 120 has a nose socket 1211. During use, an operator blows air into the nose piece structure 120 using the mouthpiece 112 and the atomized droplets are sprayed through the nose piece 1211 into the nasal cavity.
The nosepiece structure 120 further includes a fluid passage 124 such that, in order to spray liquid, the nosepiece 1211 is at least capable of communicating with the fluid passage 124 such that liquid within the container assembly 200 can be sprayed toward the nosepiece 1211 via the fluid passage 124. The barrier 130 has at least a locked position and an open position relative to the nosepiece structure 120, the locked position for closing the fluid passage 124 and the open position for opening the fluid passage 124, the barrier 130 in the locked position when the atomizing assembly 100 is coupled to the container assembly 200 containing the liquid, the liquid having a tendency to flow to the fluid passage 124 under the power of the container assembly 200, and the air flow created by the air blow when the air blow is blown to the mouthpiece 112 pushing the barrier 130 from the locked position to the open position to cause the liquid to be ejected through the fluid passage 124 to the nosepiece 1211 under the power of the power.
The nose piece structure 120 also includes an auxiliary channel 123 through which the air stream blown in through the mouthpiece 112 can also provide the driving force for the ejection of liquid. The air flow blown through the blowing nozzle 112 can assist in both the acceleration of the liquid jet and the atomization of the liquid, and the spray rate and the spray particle size distribution can be improved by means of the power source and the air flow double-power driving mode, so that the treatment effect can be improved.
When the blocking member 130 is in the blocking position, the fluid passage 124 is blocked, and the liquid in the container assembly 200 cannot be ejected, but the fluid has a tendency to be ejected under the driving action of the power source, and is in a state to be ejected. In the case of blowing the mouthpiece 112, the barrier 130 is urged to move to the open position by the air flow, and liquid is ejected through the fluid passage 124 towards the mouthpiece 1211 by the drive of the power source within the container assembly 200. The process of triggering the spray does not require a pressing operation, and only the blowing is required to open the fluid channel 124 and assist the liquid spray, thereby reducing the operation difficulty of the nasal spray device 300.
Illustratively, the atomizing assembly 100 and the container assembly 200 are removable structures, in other words, the container assembly 200 is replaceable. In this way, the aerosolization assembly 100 can be reused, one aerosolization assembly 100 can be matched to different doses of container assemblies 200, different doses of medication can be delivered, and different container assemblies 200 of the same dose can be replaced. To provide the atomizing assembly 100 with reusable characteristics, the barrier 130 can be switched relative to the nose piece structure 120 between a locked position and an unlocked position, wherein the atomizing assembly 100 remains in the locked position without being pushed by the air flow.
Without limitation, the container assembly 200 may be a single-use component.
In some alternative embodiments, with the atomizing assembly 100 connected to the container assembly 200, the atomizing assembly 100 triggers the valve structure of the container assembly 200 to be in an open state such that liquid has a tendency to flow to the fluid passage 124 upon actuation of the power source of the container assembly 200.
In the case where the atomizing assembly 100 is not connected to the container assembly 200, the valve structure of the container assembly 200 is in a closed state, so that undesired liquid ejection due to false triggering can be avoided. When the atomizing assembly 100 is connected with the container assembly 200, the atomizing assembly 100 triggers the valve structure to switch to the open state, at least part of the liquid can flow upwards from the container assembly 200, but the liquid can not be continuously sprayed due to the blocking effect of the blocking member 130, and the liquid is in a state to be sprayed. When the operator is ready (e.g., aligns the nasal mouthpiece 1211 with the nasal cavity and the mouthpiece 112 with the oral cavity), the liquid ejection may be eventually achieved after insufflation through the mouthpiece 112. Therefore, the connection between the atomizing assembly 100 and the container assembly 200 is utilized in the embodiments of the present disclosure, that is, the connection and fixation between the atomizing assembly 100 and the container assembly 200 are realized, and the valve structure is opened, so that the liquid is in the state to be sprayed, and the operation is more efficient and convenient.
Referring to fig. 4-6, in some alternative embodiments, the nose piece structure 120 includes a nose piece body 121 and a push post 122, the nose piece body 121 having a nose piece 1211, a fluid passage 124, and an auxiliary passage 123, the push post 122 being coupled to the nose piece body 121, the push post 122 pushing the valve structure to move to place the valve structure in an open state with the atomizing assembly 100 coupled to the container assembly 200.
Illustratively, the atomizing assembly 100 is assembled with the container assembly 200 from top to bottom, and during assembly, the push posts 122 are gradually moved closer together until they come into contact with the valve structure, thereby pushing the valve structure into movement, effecting a switching of the valve structure from the closed state to the open state. That is, the valve opening structure can be operated by the connection of the atomizing assembly 100 and the container assembly 200, and the operation is simple.
The push post 122 and the nose piece body 121 may be integral components, which may be integrally formed, thereby simplifying the nose piece structure 120. However, the connection between the pushing post 122 and the nose piece body 121 may be realized by, for example, fastening, bonding, or the like, although not limited thereto, the pushing post 122 and the nose piece body 121 may be formed as a separate structure.
In some alternative embodiments, as shown in fig. 4, the push post 122 is located at the bottom of the nosepiece body 121, and the nosepiece 1211 is formed as an outlet of the fluid channel 124, with an inlet 1243 of the fluid channel 124 surrounding the periphery of the push post 122. The pushing post 122 is located below the fluid channel 124, and in order to ensure that the liquid smoothly enters the fluid channel 124 and not affect the triggering function of the valve structure, the inlet 1243 of the fluid channel 124 is designed as a "winding port" as shown in fig. 4. The number of inlets 1243 of the fluid passage 124 may be one, two, or more. When the number of inlets 1243 of the fluid passage 124 is plural, the plurality of inlets 1243 are evenly distributed around the outside of the push column 122. Fig. 4 schematically illustrates inlets 1243 of two fluid channels 124.
As can be seen in the implementation shown in fig. 4 to 6, the push post 122 is provided protruding downwards at the bottom of the nose piece body 121. The fluid passage 124 is located approximately at the center of the nose piece structure 120, and the push post 122 is approximately coaxially disposed with the fluid passage 124. As shown in fig. 13 and 15, the valve passages 241 (further referred to below) of the valve structure through which the liquid passes are generally coaxially disposed with the fluid passages 124, where the "axis" may refer to the center of the respective passages. The valve passage 241 is located at a substantially central location of the container assembly 200.
In some alternative embodiments, as shown in FIG. 8, the barrier 130 includes a via 1311, the via 1311 being in communication with the fluid passage 124 when the barrier 130 is in the open position as shown in FIGS. 15 and 16 to allow liquid to enter the fluid passage 124 through the via 1311, and the via 1311 being offset from the fluid passage 124 when the barrier 130 is in the closed position as shown in FIGS. 12 and 13 to block liquid from entering the fluid passage 124.
Illustratively, to ensure a smooth passage of liquid, the inner diameter of the through-hole 1311 is approximately equal to the inner diameter of the fluid passage 124, and the through-hole 1311 is approximately coaxial with the fluid passage 124 when the stopper 130 is in the open position.
In some alternative embodiments, as shown in FIG. 6, the nosepiece structure 120 further has a first receiving chamber 126, the barrier 130 is movably disposed within the first receiving chamber 126, the first receiving chamber 126 divides the fluid passage 124 into a first chamber 1241 and a second chamber 1242, the first chamber 1241 is in communication with the nosepiece 1211, the barrier 130 is in a locked position for at least partially admitting liquid into the second chamber 1242 under the power of the container assembly 200, the barrier 130 blocks the admitting liquid into the first chamber 1241, and the barrier 130 is moved to an open position for injecting liquid into the second chamber 1242 through the aperture 1311 and the first chamber 1241 in sequence toward the nosepiece 1211.
Illustratively, as shown in FIG. 3, the first receiving chamber 126 may be in communication with the mouthpiece 112 such that the flow of air blown by the mouthpiece 112 enters the first receiving chamber 126 to urge the barrier 130 to move.
In some alternative embodiments, as shown in FIG. 3, the atomizing assembly 100 further includes a first resilient member 140, one end of the first resilient member 140 being in a fixed state relative to the nose piece structure 120, and the other end of the first resilient member 140 being coupled to the blocking member 130 to provide a resilient force for maintaining the blocking member 130 in the blocking position.
The blocking member 130 is maintained in the locking position by the elastic action of the first elastic member 140. When the pushing force of the air flow blown through the mouthpiece 112 is greater than the elastic force of the first elastic member 140, the blocking member 130 may be switched from the locking position to the opening position. After the blowing is stopped, the blocking member 130 is returned to the locking position by the first elastic member 140, so that the blocking member 130 can be switched between the locking position and the opening position.
The first elastic member 140 is a spring or a leaf spring, but is not limited thereto.
Fig. 3 and 6 exemplarily show that the first elastic member 140 is a compression spring, the left side of the first receiving chamber 126 is closed, the right side thereof is opened, the first elastic member 140 is located between the left side wall of the first receiving chamber 126 and the left end of the blocking member 130, and the right side opening of the first receiving chamber 126 is communicated with the mouthpiece 112.

The barrier 130, when in the locked position, may close both the fluid passage 124 and possibly the auxiliary passage 123, thus preventing gas from entering the atomizing assembly 100 in the unused state and reducing contamination of the atomizing assembly 100.
To further enhance the hygiene of the atomizing assembly 100, a cap may be added to the atomizing assembly 100, which cap covers at least the nasal sockets 1211.

After the atomizing assembly 100 is connected to the container assembly 200, the seal 400 is positioned between the top wall of the retaining groove 125 and the top wall of the retaining post to prevent leakage of liquid from the container assembly 200 through the connection between the nose piece structure 120 and the container assembly 200.
Without limitation, the seal 400 may be a separate component from the nose piece structure 120, and upon assembly of the atomizing assembly 100 and the container assembly 200, the seal 400 is placed within the retaining groove 125 and then the atomizing assembly 100 is assembled with the container assembly 200.
The seal 400 may be a flexible sealing gasket, but is not limited thereto.

As shown in fig. 6, the atomizing chip 150 is positioned within a stationary chamber 1244 within the nose piece structure 120, the stationary chamber 1244 being positioned within the fluid passage 124 and between the nose piece 1211 and the first receiving chamber 126, and there being no relative movement or rotation between the atomizing chip 150 and the nose piece structure 120.
In some alternative embodiments, as shown in FIG. 7, the mouthpiece structure 110 further comprises a mouthpiece body 111, the mouthpiece body 111 being coupled to the container assembly 200 and having a second receiving chamber 113 for receiving the nose piece 120 and an ejection orifice 1111 in communication with the nose piece 1211, the mouthpiece 112 being coupled to the mouthpiece body 111, the atomizing assembly 100 pushing the valve structure of the container assembly 200 to move to an open state when the mouthpiece body 111 and the container assembly 200 are assembled in place.
The jet 1111 is used, for example, in the nasal mouthpiece 1211 to ensure smooth ejection of the mist droplets to the nasal cavity.
The mouthpiece body 111 and mouthpiece 112 may be a unitary component and the mouthpiece structure 110 may be formed by integral molding.
Illustratively, the mouthpiece 110 and the nosepiece 120 may be removable structures.
The second receiving chamber 113 communicates with the mouthpiece 112 and the jet orifice 1111, respectively, and the nose piece structure 120 is mounted in the second receiving chamber 113 such that the opening of the first receiving chamber 126 communicates with the mouthpiece 112 and the nose piece 1211 is aligned with the jet orifice 1111.
The mouthpiece structure 110 serves as both a carrier to which the nose-piece structure 120 is mounted and also provides for blowing of the mouthpiece 112 for multiple purposes.
In some alternative embodiments, the mouthpiece body 111 is provided with threads, and fig. 7 illustrates the threads of the mouthpiece body 111 as internal threads 115. The mouthpiece body 111 is threadably coupled to the container assembly 200. The mouthpiece 110 is also used to attach the container assembly 200 to enable assembly of the two. The threaded connection mode is simple and reliable.
In other embodiments, the mouthpiece body 111 may also be assembled with the container assembly 200 by other means (e.g., snap-fit connection, screw connection).
In some alternative embodiments, as shown in fig. 7, the mouthpiece body 111 further includes a nose piece retaining plate 114 coupled to an inner wall of the second receiving chamber 113, the nose piece retaining plate 114 having a mounting hole 1141, and as shown in fig. 3, the nose piece structure 120 is disposed through the mounting hole 1141.
The nose piece structure 120 can be fixed by the nose piece fixing plate 114, and the reliability of the connection between the nose piece structure 120 and the mouthpiece structure 110 is ensured.
In connection with the foregoing description, the nose piece fixing plate 114 is located at the upper portion of the nose piece structure 120, the fixing groove 125 is located at the bottom of the nose piece structure 120, and when the atomizing assembly 100 is connected with the container assembly 200, the nose piece fixing plate 114 at least prevents the nose piece structure 120 from moving upwards, and the mating portion of the fixing groove 125 and the container assembly 200 at least prevents the nose piece structure 120 from moving downwards, thus ensuring the installation and fixation of the nose piece structure 120.
In some alternative embodiments, as shown in connection with fig. 3 and 6, the outer diameter of the nosepiece structure 120 increases gradually from the nosepiece retaining plate 114 toward the container assembly 200. After the nose bearing structure 120 is inserted into the mounting hole 1141 of the nose bearing fixing plate 114, the nose bearing structure 114 cannot completely pass through the mounting hole 1141 due to the gradual increase of the outer diameter thereof, so that the nose bearing fixing plate 114 plays a role in fixing the nose bearing structure 120. The nose bearing structure 120 and the mouth bearing structure 110 can be assembled and disassembled without using any tools, and the method is simple and convenient.
In some alternative embodiments, as shown in FIG. 7, the mouthpiece 112 includes a first section 1121 and a second section 1122, one end of the first section 1121 forms an inlet of the mouthpiece 112, the other end of the first section 1121 is connected to the second section 1122, and as shown in FIG. 3, the atomizing assembly 100 further includes a connecting tube 160 positioned within the second section 1122 and in communication with the first section 1121 and the first receiving chamber 126, respectively. The connecting tube 160 may better engage the first receiving chamber 126 and the first segment 1121 to ensure that the air flow has sufficient velocity to push the barrier 130 and drive atomization.
In some alternative embodiments, the cross-section of the connecting tube 160 tapers toward the nose piece structure 120.
Illustratively, the connecting tube 160 is a cylindrical hollow tube of varying diameter, the larger diameter end is fixed to the second section 1122, the smaller diameter end is disposed in the first receiving cavity 126 of the nose-piece structure 120, and the connecting tube 160 is completely adhered to the surface without any relative movement or rotation when assembled with the nose-piece structure 120 and the mouth-piece structure 110.
As shown in fig. 8, one end of the blocking member 130 has a first groove 134, and as shown in fig. 6, a second groove 1261 opposite to the first groove 134 is provided at the left side of the first receiving chamber 126, and both ends of the first elastic member 140 are respectively positioned in the first groove 134 and the second groove 1261 to improve the reliability of the assembly of the first elastic member 140.
Referring to fig. 8, the other end of the blocking member 130 has an arc-shaped end surface 133, the through hole 1311 is located at a substantially middle position of the blocking member 130, and the limiting protrusion 132 is located between the through hole 1311 and the arc-shaped end surface 133, which can make the arc-shaped end surface 133 fit with the inner wall of the mouthpiece 110, but not push the connection tube 160 due to the elastic force of the first elastic member 140 when reset, which is beneficial to protecting the reliability of the installation of the connection tube 160.
When the user holds the mouthpiece 112, the nasal sockets 1211 are placed in the nasal cavity. When the air is forcibly blown, the air flows through the first section 1121 of the mouthpiece 112 and the connection pipe 160 in this order. Because the air flow passage cross section is gradually reduced, the air flow velocity is gradually increased. A portion of the high-velocity air flow pushes the blocking member 130 to the left, and the first elastic member 140 is compressed. During the movement of the blocking member 130, the through hole 1311 gradually communicates with the fluid channel 124 of the nose bearing structure 120, and the liquid in the second chamber 1242 rapidly moves up to the first chamber 1241 under the action of the internal pressure of the medicine bottle, and enters the nasal cavity after being atomized by the atomizing chip 150.
In addition, another portion of the gas escapes from both sides of the mouthpiece 1211 after moving up through the auxiliary channel 123. The auxiliary air flow can continuously disperse atomized liquid drops on one hand and accelerate the liquid drops on the other hand, so that the speed of the atomized aerosol entering the nasal cavity is increased, and the atomized aerosol is delivered to a deeper part in the nasal cavity.
Example 2
The container assembly 200 of the present embodiment is described in further detail below in conjunction with fig. 9 and 10.
The container assembly 200 of the presently disclosed embodiments is for use in connection with the atomizing assembly 100 described in embodiment 1.
The container assembly 200 of the present embodiment includes all the technical features of the container assembly 200 of embodiment 1, and a description thereof will not be repeated.
As shown in fig. 10, the container assembly 200 includes a can 210 and a pouch 220, the pouch 220 is positioned in the can 210, an inner cavity of the pouch 220 is used to contain a liquid, a space 201 is provided between the pouch 220 and the can 210, and a power source is accommodated in the space 201.
The power source may be, without limitation, compressed gas. The liquid in the bag 220 can enter the fluid channel 124 under the pressure of the power source, the atomizing power source of the liquid mainly comes from the compressed gas between the bag 220 and the tank 210, and the atomizing driving power mainly comes from the blowing power of the blowing nozzle 112.
The container assembly 200 may further include a valve seat 230, the valve seat 230 connecting the can 210 and the pouch 220, respectively, to seal the compartment 201.
The container assembly 200 may also include a valve structure for opening or closing the pouch 220, the power source compressing the pouch 220 to provide a driving force for the injection of liquid when the valve structure is in an open state.
In some alternative embodiments, with continued reference to FIG. 10, the valve structure includes a valve body 240, a check valve 250, and a second resilient member 260, the valve body 240 having a valve passageway 241, the valve passageway 241 being in communication with the interior cavity of the bag body 220, the check valve 250 being movably mounted within the valve passageway 241, the second resilient member 260 having one end fixed relative to the valve body 240 and the other end connected to the check valve 250, the second resilient member 260 being adapted to retain the check valve 250 in a position closing the valve passageway 241 such that the valve structure is in a closed state, the atomizing assembly 100 pushing the check valve 250 against the resilience of the second resilient member 260 such that the check valve 250 opens the valve passageway 241, the valve structure being in an open state, upon connection of the atomizing assembly 100 with the container assembly 200.
The check valve 250 is maintained in a closed state by the elastic action of the second elastic member 260. When the atomizing assembly 100 is in place, the atomizing assembly 100 pushes the check valve 250 against the elastic force of the second elastic member 260, and the check valve 250 can be switched from the closed state to the open state.
The second elastic member 260 is a compression spring or a shrapnel, but is not limited thereto.
In some alternative embodiments, as shown in FIG. 10, the valve channel 241 includes an upper channel 2411, a lower channel 2413, and a transition channel 2412, both ends of the transition channel 2412 are respectively communicated with the upper channel 2411 and the lower channel 2413, the inner diameter of the lower channel 2413 is larger than the inner diameter of the upper channel 2411, the bottom inner diameter of the transition channel 2412 is larger than the top inner diameter of the transition channel 2412, the one-way valve 250 includes a base 251 and a driving part 252 connected to the base 251, the maximum outer diameter of the base 251 is larger than the minimum inner diameter of the transition channel 2412, the outer diameter of the driving part 252 is smaller than the inner diameter of the upper channel 2411 and is positioned in the upper channel 2411, the base 251 is in contact with the inner wall of the transition channel 2412 to close the valve channel 241 when the valve structure is in the closed state, and a gap is provided between the base 251 and the inner wall of the transition channel 2412 to open the valve channel 241 when the valve structure is in the open state.
The "inner diameter" and "outer diameter" may both be diameters.
Illustratively, the drive portion 252 and the base portion 251 are of unitary construction, and the check valve 250 may be formed by an integral molding.
With the atomizing assembly 100 connected to the container assembly 200, the push post 122 of the atomizing assembly 100 interfaces with the driving portion 252 of the check valve 250, and the push post 122 pushes the driving portion 252 to move downward, thereby opening the valve channel 241.
The maximum outer diameter of the base 251 is greater than the minimum inner diameter of the transition channel 2412, where the base 251 cannot pass through the transition channel 2412, where it limits the movement of the one-way valve 250. When the check valve 250 is stuck to the inner wall of the transition channel 2412 under the limiting action of the transition channel 2412, the liquid below cannot flow upward, that is, 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 large, when the pushing post 122 pushes the check valve 250 to move downward, the check valve 250 can move toward the lower channel 2413, a gap is generated between the check valve 250 and the inner wall of the valve channel 241, and the valve channel 241 is opened.
The second elastic member 260 is compressed or restored as the check valve 250 moves up and down.
As can be seen from the implementation shown in fig. 10, the base 251 increases in outside diameter from top to bottom, and the inner diameter of the transition channel 2412 increases in inside diameter from top to bottom. The base 251 has an outer diameter greater than or equal to the inner diameter of the upper channel 2411 at a substantially middle position, and the check valve 250 cannot move into the upper channel 2411.
In some alternative embodiments, the valve structure shown in FIG. 10 further includes a valve core 280, where the valve core 280 is at least partially positioned below the valve body 240 and is connected to the valve body 240, and where the valve core 280 has a flow passage 281, where the flow passage 281 communicates with the valve passage 241 and the interior cavity of the bag 220, respectively.
The valve channel 241 is used for the transport of liquid and the valve body 240 and valve core 280 are placed inside the bag 220. The valve body 240 and the valve core 280 are assembled in a sealing manner without relative movement or rotation, one end of the second elastic member 260 is fixed to the top surface of the valve core 280, and the other end of the second elastic member 260 is fixed to the lower end surface of the check valve 250. It will be appreciated that the end of the second elastic member 260 may be fixed in other manners than the top end of the valve core 280, for example, the inner wall of the valve passage 240 of the valve body 240 may extend inward to form a boss, and the end of the second elastic member 260 may be fixed to the boss.
Illustratively, the valve body 240 at least partially protrudes out of the canister 210, and the top of the valve body 240 may act as a securing post for a plug-in engagement with the securing slot 125 of the atomizing assembly 100 described above.
The valve core 280 is located below the valve body 240, and the liquid in the bag 220 enters the flow passage 281 first, and then enters the valve channel 241 through the flow passage 281. The valve core 280 extends the valve channel 241 so that liquid in the bag 220 can more easily enter the valve channel 241.
With continued reference to fig. 10, in some alternative embodiments, the second resilient member 260 is connected at one end to the top of the valve spool 280 and at the other end to the bottom of the check valve 250. The valve core 280 may serve as a carrier to which the second elastic member 260 is fixed, in addition to providing the flow passage 281.
In some alternative embodiments, the container assembly 200 further includes an upper cap 270 mounted on the valve seat 230, the upper cap 270 or the exterior of the valve seat 230 being threaded for connection to the atomizing assembly 100.
In the implementation shown in fig. 9 and 10, the threads are formed on the outer circumference of the upper cover 270, i.e., the external threads 271. The upper cover 270 is positioned on the upper part of the valve seat 230 and is assembled with the valve seat 230 in a coaxial sealing way without relative rotation. The upper cap 270 has external threads 271 on its peripheral cylindrical surface that are designed to mate with the internal threads 115 on the lower end of the mouthpiece 110 of the atomizing assembly 100.
In some alternative embodiments, as shown in FIGS. 9 and 10, the container assembly 200 further includes a closure member 290, the closure member 290 removably covering the outlet of the valve structure, wherein the liquid is ejected through the outlet of the valve structure.
The closure 290 is formed over the top of the valve body 240 and may be formed of a flexible plastic material, and the closure 290 may be torn off or the closure 290 may be pierced during use of the container assembly 200. The sealing member 290 at the top end of the valve body 240 can be designed as a threaded medicine bottle cap or a plastic bottle cap, and only needs to be rotated to unscrew or pull out the bottle cap when in use.
Example 3
The nasal spray device 300 is characterized in that the nasal spray device 300 comprises the atomizing assembly 100 of embodiment 1 and the container assembly 200 of embodiment 2.
The general process of assembling the atomizing assembly 100 with the container assembly 200 involves first removing the closure 290 from the top end of the container assembly 200, placing a flexible sealing gasket (a specific form of seal 400) in the mounting groove 125 in the lower end of the atomizing assembly 100, and then mating it with the mounting groove 125 in the top end of the upper cap 270. Then, the push column 122 at the bottom end of the nose piece structure 120 pushes the check valve 250 in the container assembly 200 to move downward by rotating downward, and the second elastic member 260 at the lower end is compressed, at this time, the valve passages 241 at the upper and lower ends of the check valve 250 are communicated. At the same time, the internal threads 115 on the lower end of the mouthpiece 110 mate with threads on the outside of the upper cap 270, completing the sealed securement of the two components during rotation.
The bag-and-valve container assembly 200 is designed as a replaceable assembly, and when the liquid medicine in the container assembly 200 is used, the two parts of the assembly can be separated by rotating the atomizing assembly 100, and then a new medicine bottle is replaced, and the assembly is continuously used after being reassembled.
The general use of the nasal spray device 300 includes an initial state, an atomization process, and a reset process.
In the initial state, as shown in fig. 12 and 13, 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 bearing structure 120. Under the pressure of the compressed gas between the tank 210 and the bag 220, the liquid in the bag 220 flows through the flow passage 281, the valve passage 241, and the inlet of the fluid passage 124 in this order, and enters the second chamber 1242 of the fluid passage 124. At this time, the barrier 130 completely separates the first chamber 1241 and the second chamber 1242, and the liquid cannot enter the upper portion of the atomizing assembly 100.
Referring to fig. 15 and 16, when the user holds the mouthpiece 112, the nasal mouthpiece 1211 is placed within the nasal cavity. When the air is blown forcibly, the air flows through the mouthpiece 112 and the connection pipe 160 in this order. Because the section of the airflow passage has a gradually decreasing cross section, the airflow velocity gradually increases. A portion of the high-velocity air flow pushes the blocking member 130 to the left, and the first elastic member 140 is compressed. During the movement of the blocking member 130, the through hole 1311 gradually communicates with the first chamber 1241 and the second chamber 1242 of the nose bearing structure 120, and the liquid in the second chamber 1242 moves upward rapidly under the pressure of the container assembly 200, and enters the nasal cavity after being atomized by the atomizing chip 150.
In addition, another portion of the gas enters the auxiliary channel 123 through the first receiving chamber 126, and after the gas flow moves up, overflows from both sides of the mouthpiece 1211. The auxiliary air flow can continuously disperse atomized liquid drops on one hand and accelerate the liquid drops on the other hand, so that the speed of the atomized aerosol entering the nasal cavity is increased, and the atomized aerosol is delivered to a deeper part in the nasal cavity. This process is an atomization process.
When the blowing of air into the mouth-blowing nozzle 112 is stopped, the compressed first elastic member 140 releases the elastic force, and pushes the blocking member 130 to reset until the outer edge cambered surface of the blocking member 130 is completely attached to the outer cambered surface of the lower end of the nose-bearing structure 120. At this time, the through hole 1311 gradually moves to the right during the resetting process of the blocking member 130, the solid portion of the blocking member 130 gradually separates the first chamber 1241 and the second chamber 1242 of the nose bearing structure 120, the fluid channel 124 is gradually disconnected, and atomization is stopped after the fluid channel 124 is completely disconnected. This process is a reset process.
On the premise of no conflict, different embodiments or different technical features of the present disclosure can be arbitrarily combined to form a new embodiment.
It should be understood that the above examples are illustrative and are not intended to encompass all possible implementations encompassed by the claims. Various modifications and changes may be made in the above embodiments without departing from the scope of the disclosure. Likewise, the individual features of the above embodiments can also be combined arbitrarily to form further embodiments of the invention which may not be explicitly described.
