Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to an atomizing assembly, a container assembly and a nasal spray device. Background Art

[0002] The lateral wall of the nasal cavity is composed of the three nasal conchae (superior, middle, and inferior) and their corresponding nasal passages. The nasal septum is located inside, and the posterior nasal aperture connects to the pharynx. Traditional nasal devices target drug delivery to the inferior nasal space, where the epithelium is not optimal for drug absorption and the likelihood of drug clearance increases due to nasal drip, 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, rich blood vessels, and increased permeability, making it an ideal pathway for rapid drug absorption into the systemic circulation. To ensure the targeted delivery and therapeutic effect of the drug spray through the nasal cavity, parameters such as the spray rate and spray particle size distribution of the nasal spray device need to be rationally controlled.

[0003] In order to achieve the goal of delivering more drugs deep into the nasal cavity, common methods include lengthening the atomizer nozzle or increasing the atomization driving force. However, in the above methods, an overly long atomizer nozzle may cause discomfort to the patient during use. Increasing the atomization driving force generally involves manually pressing the pump assembly to spray the drug while adding an additional oral blowing method, using the airflow from the mouth to assist in increasing the driving force. This requires the coordination of pressing and blowing, and requires a high level of hand-mouth coordination from the operator. Summary of the Invention

[0067] Effects of the Invention

[0068] In the disclosed embodiment, when the blocking member is in the locked position, the fluid passage is blocked, preventing the liquid in the container assembly from being ejected. When air is blown into the mouthpiece, the airflow propels the blocking member to the open position. Driven by a power source within the container assembly, the liquid is ejected through the fluid passage toward the nasal opening. The airflow from the mouthpiece also drives the liquid ejection, which then enters the nasal cavity through the nasal opening. No pressing is required; simply blowing air can both open the fluid passage and assist in liquid ejection, reducing the difficulty of operating the nasal spray device.

[0069] Moreover, the airflow blown in through the mouthpiece can not only assist in accelerating the liquid injection, but also assist in the atomization of the liquid. This dual-power drive mode with the help of power source and airflow can improve the spray rate and spray particle size distribution, and enhance the treatment effect.

[0093] Example 1

[0094] The atomizing assembly 100 provided in the embodiment of the present disclosure is used in conjunction with the container assembly 200. Figure 11 As shown, the atomizer assembly 100 and the container assembly 200 are assembled to form a nasal spray device 300. The container assembly 200 includes a power source and a container. Without limitation, 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 from the container toward the atomizer assembly 100, and the liquid ultimately enters the nasal cavity in an atomized state, achieving nasal drug delivery.

[0095] Reference below Figures 1 to 8 , and combined with Figures 11 to 17 The atomizer assembly 100 according to an embodiment of the present disclosure is described in detail.

[0096] See also Figures 1 to 3 As shown, the atomizing assembly 100 includes a mouthpiece structure 110, a nosepiece structure 120 and a blocking member 130 ( Figure 3 ), wherein the mouthpiece structure 110 has a mouthpiece 112, and the nasal piece structure 120 has a nasal piece opening 1211. During use, the operator uses the mouthpiece 112 to blow air into the nasal piece structure 120, and the atomized droplets are sprayed into the nasal cavity through the nasal piece opening 1211.

[0097] The nasal piece structure 120 also includes a fluid channel 124. To allow liquid to be sprayed, the nasal opening 1211 is at least able to communicate with the fluid channel 124, so that the liquid in the container assembly 200 can be sprayed toward the nasal opening 1211 through the fluid channel 124. The blocking member 130 has at least a locked position and an unlocked position relative to the nasal piece structure 120. The locked position closes the fluid channel 124, and the unlocked position opens the fluid channel 124. When the atomizer 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 toward the fluid channel 124 under the power source of the container assembly 200. When air is blown into the mouthpiece 112, the airflow generated by the blowing pushes the blocking member 130 from the locked position to the unlocked position, allowing the liquid to be sprayed toward the nasal opening 1211 through the fluid channel 124 under the power source.

[0098] The nosepiece structure 120 also includes an auxiliary channel 123. Airflow blown through the mouthpiece 112 can also provide driving force for liquid ejection through the auxiliary channel 123. The airflow blown through the mouthpiece 112 can both assist in liquid ejection acceleration and liquid atomization. This dual-powered mode of driving by a power source and airflow can improve the spray rate and spray particle size distribution, thereby enhancing the therapeutic effect.

[0099] When the blocking member 130 is in the locked position, the fluid passage 124 is blocked, and the liquid in the container assembly 200 cannot be sprayed. However, driven by the power source, the fluid has a tendency to spray and is in a state ready for spraying. When blowing air into the mouthpiece 112, the airflow pushes the blocking member 130 to the open position. Driven by the power source within the container assembly 200, the liquid is sprayed through the fluid passage 124 toward the nasal opening 1211. The process of triggering the spray does not require a pressing operation; simply blowing air can both open the fluid passage 124 and assist in the spraying of the liquid, reducing the difficulty of operating the nasal spray device 300.

[0100] Exemplarily, the atomizer assembly 100 and the container assembly 200 are detachable structures. In other words, the container assembly 200 is replaceable. This allows the atomizer assembly 100 to be reused. One atomizer assembly 100 can be paired with container assemblies 200 of different dosages to deliver different doses of medication, and different container assemblies 200 of the same dosage can also be replaced. To ensure the reusability of the atomizer assembly 100, the barrier 130 can be switched between a locked position and an open position relative to the nosepiece structure 120. In the absence of airflow, the atomizer assembly 100 remains in the locked position.

[0101] Without limitation, container assembly 200 may be a single-use component.

[0102] In some optional embodiments, when the atomizer assembly 100 is connected to the container assembly 200, the atomizer assembly 100 triggers the valve structure of the container assembly 200 to be in an open state, so that the liquid tends to flow toward the fluid channel 124 under the driving action of the power source of the container assembly 200.

[0103] When the atomizer 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 the unwanted liquid ejection caused by the false trigger can be avoided. When the atomizer assembly 100 is connected to the container assembly 200, the atomizer assembly 100 triggers the valve structure to switch to the open state, and at least part of the liquid will flow upward from the container assembly 200, but due to the blocking effect of the blocking member 130, the liquid will not continue to be sprayed and will be in a state to be sprayed. When the operator is ready (for example, aligning the nasal opening 1211 with the nasal cavity and the mouthpiece 112 with the oral cavity), the liquid can be finally sprayed after blowing through the mouthpiece 112. Therefore, the embodiment of the present disclosure utilizes the connection between the atomizer assembly 100 and the container assembly 200, that is, the connection between the atomizer assembly 100 and the container assembly 200 is fixed, and the valve structure is also opened, so that the liquid is in a state to be sprayed, killing two birds with one stone, and the operation is more efficient and convenient.

[0104] See also Figures 4 to 6 As shown, in some optional embodiments, the nose piece structure 120 includes a nose piece body 121 and a push column 122. The nose piece body 121 has a nose piece opening 1211, a fluid channel 124 and an auxiliary channel 123. The push column 122 is connected to the nose piece body 121. When the atomizer assembly 100 is connected to the container assembly 200, the push column 122 pushes the valve structure to move so that the valve structure is in an open state.

[0105] For example, the atomizer assembly 100 is assembled with the container assembly 200 from top to bottom. During the assembly process, the push rod 122 gradually approaches until it contacts the valve structure, thereby pushing the valve structure to move, thereby switching the valve structure from a closed state to an open state. In other words, the valve structure can be opened by connecting the atomizer assembly 100 and the container assembly 200, which is simple to operate.

[0106] The push post 122 and the nose piece body 121 can be integral components and can be formed in one piece, which can simplify the nose piece structure 120. However, this is not limiting. For example, the push post 122 can be a separate structure from the nose piece body 121, and the push post 122 and the nose piece body 121 can be connected by means of snap-fitting, bonding, etc.

[0107] In some optional embodiments, such as Figure 4As shown, the push column 122 is located at the bottom of the nosepiece body 121, and the nosepiece 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 column 122. The push column 122 is located below the fluid channel 124. In order to ensure that the liquid enters the fluid channel 124 smoothly without affecting the triggering function of the valve structure, the inlet 1243 of the fluid channel 124 is designed to be Figure 4 The number of the inlet 1243 of the fluid channel 124 can be one, two, or more. When there are multiple inlet 1243 of the fluid channel 124, the multiple inlet 1243 are evenly distributed around the outside of the push column 122. Figure 4 The inlets 1243 of two fluid channels 124 are shown as an example.

[0108] from Figures 4 to 6 As can be seen from the embodiment shown, the push column 122 is provided at the bottom of the nose piece body 121 and protrudes downward. The fluid channel 124 is located approximately at the center of the nose piece structure 120, and the push column 122 and the fluid channel 124 are approximately coaxially distributed. Figure 13 and Figure 15 As shown, the valve channel 241 (described further below) for liquid passage in the valve structure is approximately coaxial with the fluid channel 124 , where “axis” refers to the center of the corresponding channel. The valve channel 241 is located approximately in the center of the container assembly 200 .

[0109] In some optional embodiments, such as Figure 8 As shown, the blocking member 130 includes a through hole 1311. The blocking member 130 is located as shown in FIG. Figure 15 and Figure 16 When in the open position shown, the through hole 1311 is connected to the fluid channel 124, so that the liquid enters the fluid channel 124 through the through hole 1311; the blocking member 130 is in the open position shown. Figure 12 and Figure 13 In the locked position shown, the through hole 1311 is offset from the fluid channel 124 to prevent liquid from entering the fluid channel 124 .

[0110] Illustratively, to ensure smooth passage of liquid, the inner diameter of the through hole 1311 is substantially 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 substantially coaxial.

[0111] In some optional embodiments, such as Figure 6As shown, the nasal socket structure 120 also has a first accommodating cavity 126, and the blocking member 130 is movably located in the first accommodating cavity 126; the first accommodating cavity 126 separates the fluid channel 124 into a first chamber 1241 and a second chamber 1242, and the first chamber 1241 is connected to the nasal socket opening 1211; when the blocking member 130 is in the locked position, the 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 the liquid from entering the first chamber 1241; when the blocking member 130 moves to the open position, the liquid in the second chamber 1242 is sprayed toward the nasal socket opening 1211 through the hole 1311 and the first chamber 1241 in sequence.

[0112] For example, Figure 3 As shown, the first accommodating cavity 126 may be in communication with the mouthpiece 112 , so that the airflow blown into the mouthpiece 112 enters the first accommodating cavity 126 to push the blocking member 130 to move.

[0113] In some optional embodiments, such as Figure 3 As shown, the atomizer assembly 100 further includes: a first elastic member 140, one end of the first elastic member 140 is in a fixed state relative to the nose support structure 120, and the other end of the first elastic member 140 is connected to the blocking member 130 to provide elastic force for keeping the blocking member 130 in the locked position.

[0114] The first elastic member 140 acts to maintain the blocking member 130 in the locked position. When the force of the airflow entering through the mouthpiece 112 exceeds the elastic force of the first elastic member 140, the blocking member 130 can be switched from the locked position to the open position. After the airflow stops, the blocking member 130 returns to the locked position under the action of the first elastic member 140, thus enabling the blocking member 130 to switch between the locked and open positions.

[0115] The first elastic member 140 is a spring or a spring, but is not limited thereto.

[0116] Figure 3 and Figure 6 As shown exemplarily, the first elastic member 140 is a compression spring, the left side of the first accommodating chamber 126 is closed, and the right side thereof is open, the first elastic member 140 is located between the left side wall of the first accommodating chamber 126 and the left end of the blocking member 130, and the right side opening of the first accommodating chamber 126 is connected to the mouthpiece 112.

[0117] In some optional embodiments, combined with Figure 13 and Figure 14 As shown, when the blocking member 130 is in the locked position, the blocking member 130 also closes the auxiliary channel 123; Figures 16 and 17As shown, 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, thereby preventing gas from entering the atomizer assembly 100 when not in use, thereby reducing contamination of the atomizer assembly 100.

[0118] In order to further improve the hygiene of the atomizer assembly 100 , a cap may be added to the outside of the atomizer assembly 100 , and the cap at least covers the nasal opening 1211 .

[0119] In some optional embodiments, such as Figure 6 As shown, the cavity wall of the first accommodating cavity 126 is provided with a limiting groove 127, and the limiting groove 127 includes a first groove wall 1271 and a second groove wall 1272 distributed in parallel along the moving direction of the blocking member 130, and 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 in the first accommodating cavity 126.

[0120] Combine Figure 8 As shown, the blocking member 130 includes a blocking body 131 and a limiting protrusion 132. The blocking body 131 is movably disposed in the first accommodating cavity 126. The blocking body 131 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 with the movement of the blocking body 131. When the blocking member 130 is in the locked position, as shown in FIG. Figure 14 As shown, the limiting protrusion 132 abuts against the first groove wall 1271, and the blocking body 131 closes the fluid channel 124 and the auxiliary channel 123 at the same time; when the blocking member 130 is in the open position, as shown Figure 17 As shown, the limiting protrusion 132 abuts against the second groove wall 1272 , the through hole 1311 is connected to the fluid channel 124 , and the auxiliary channel 123 is connected to the blowing nozzle 112 .

[0121] See also Figure 17 The entrance of the auxiliary channel 123 is located above the first accommodating chamber 126, and both the auxiliary channel 123 and the limiting groove 127 are connected to the first accommodating chamber 126. The auxiliary channel 123 may have one, two, three, or more entrances. When the blocking member 130 is in the locked position, the solid portion of the blocking member 130 simultaneously blocks the fluid channel 124 and the auxiliary channel 123, preventing external fluid from entering the auxiliary channel 123.

[0122] In some optional embodiments, such as Figure 5 and Figure 6As shown, the auxiliary channel 123 surrounds the nasal opening 1211. The airflow from the auxiliary channel 123 can help the droplets sprayed from the nasal opening 1211 to be further atomized into small 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 can be delivered to the target area.

[0123] See also Figure 3 The atomizer assembly 100 is tilted from top to bottom at the fluid outlet (including the nasal opening 1211 and the end surface of the auxiliary channel 123), so that it can better match the nasal cavity and allow more spray to be delivered to the target area.

[0124] In some optional embodiments, such as Figure 3 、 Figure 4 and Figure 6 As shown, a fixing groove 125 is provided at the bottom of the nose piece structure 120 , and the fixing groove 125 can be plugged into and matched with the fixing boss of the container assembly 200 , thereby improving the reliability of the connection between the nose piece structure 120 and the container assembly 200 .

[0125] In an embodiment not shown in the present disclosure, a fixing boss may also be provided on the nose piece structure 120 , and the fixing boss may be plugged into and engaged with the fixing groove 125 of the container assembly 200 .

[0126] In some alternative embodiments, see Figure 13 The atomizer assembly 100 further includes a seal 400, which is located within the fixing groove 125 to seal the nosepiece structure 120 and the container assembly 200. After the atomizer assembly 100 and the container assembly 200 are connected, the seal 400 is located between the top wall of the fixing groove 125 and the top wall of the fixing boss to prevent liquid in the container assembly 200 from leaking through the connection between the nosepiece structure 120 and the container assembly 200.

[0127] Without limitation, the seal 400 may be a component independent of the nose piece structure 120 . When the atomizer assembly 100 and the container assembly 200 are assembled, the seal 400 is placed in the fixing groove 125 , and then the atomizer assembly 100 and the container assembly 200 are assembled.

[0128] The sealing member 400 may be a flexible sealing gasket, but is not limited thereto.

[0129] In some optional embodiments, the atomization assembly 100 further includes: an atomization chip 150 , which is mounted on the nose piece structure 120 and located in the spray path of the liquid to atomize the sprayed liquid.

[0130] The liquid medicine is delivered to the atomization chip 150 through the fluid channel 124 to complete the atomization process.

[0131] like Figure 6As shown, the atomizer chip 150 is located in a fixed chamber 1244 inside the nose piece structure 120. The fixed chamber 1244 is located in the fluid channel 124 and between the nose piece opening 1211 and the first accommodating chamber 126. There is no relative movement or rotation between the atomizer chip 150 and the nose piece structure 120.

[0132] In some optional embodiments, such as Figure 7 As shown, the mouthpiece structure 110 also includes: a mouthpiece body 111, which is connected to the container assembly 200 and has a second accommodating cavity 113 for accommodating the nosepiece structure 120 and an injection port 1111 connected to the nosepiece opening 1211, and a mouthpiece 112 is connected to the mouthpiece body 111; when the mouthpiece body 111 and the container assembly 200 are assembled in place, the atomizer assembly 100 pushes the valve structure of the container assembly 200 to move to an open state.

[0133] The spray port 1111 is used, for example, for the nasal opening 1211 to ensure that the mist droplets are sprayed smoothly into the nasal cavity.

[0134] The mouthpiece body 111 and the mouthpiece 112 may be integral components, and the mouthpiece structure 110 may be formed in one piece.

[0135] For example, the mouthpiece structure 110 and the nosepiece structure 120 may be detachable structures.

[0136] The second accommodating cavity 113 is communicated with the mouthpiece 112 and the ejection port 1111 respectively. After the nosepiece structure 120 is installed in the second accommodating cavity 113, the opening of the first accommodating cavity 126 is communicated with the mouthpiece 112, and the nosepiece opening 1211 is aligned with the ejection port 1111.

[0137] The mouthpiece structure 110 serves as a carrier for mounting and fixing the nosepiece structure 120 and also provides a mouthpiece 112 for blowing, thus one component has multiple uses.

[0138] In some optional embodiments, the mouthpiece body 111 is provided with threads. Figure 7 The exemplary embodiment shows that the threads of the mouthpiece body 111 are internal threads 115. The mouthpiece body 111 is threadedly assembled with the container assembly 200. The mouthpiece structure 110 is also used to connect with the container assembly 200, thereby achieving the assembly of the two. The threaded connection method is simple and reliable.

[0139] In other embodiments, the mouthpiece body 111 may also be assembled with the container assembly 200 by other means (such as snap connection, screw connection).

[0140] In some optional embodiments, such as Figure 7 As shown, the mouthpiece body 111 further includes a nosepiece fixing plate 114 connected to the inner wall of the second accommodating cavity 113. The nosepiece fixing plate 114 has a mounting hole 1141. Figure 3As shown, the nose piece structure 120 is passed through the mounting hole 1141 .

[0141] The nose piece fixing plate 114 can be used to fix the nose piece structure 120 , thereby ensuring the reliability of the connection between the nose piece structure 120 and the mouth piece structure 110 .

[0142] In combination with the above description, the nose piece fixing plate 114 is located at the upper part of the nose piece structure 120, and the fixing groove 125 is located at the bottom of the nose piece structure 120. When the atomizer assembly 100 is connected to the container assembly 200, the nose piece fixing plate 114 at least prevents the nose piece structure 120 from moving upward, and the matching part of the fixing groove 125 and the container assembly 200 at least prevents the nose piece structure 120 from moving downward, thereby ensuring that the nose piece structure 120 is installed and fixed.

[0143] In some optional embodiments, combined with Figure 3 and Figure 6 As shown, the outer diameter of the nose piece structure 120 gradually increases from the nose piece fixing plate 114 toward the container assembly 200. After the nose piece structure 120 is inserted into the mounting hole 1141 of the nose piece fixing plate 114, its outer diameter gradually increases downward, preventing it from completely passing through the mounting hole 1141. Consequently, the nose piece fixing plate 114 secures the nose piece structure 120. This method eliminates the need for additional fasteners to secure the two, and allows for tool-free installation and removal of the nose piece structure 120 and mouth piece structure 110, making it simple and convenient.

[0144] In some optional embodiments, such as Figure 7 As shown, 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, and the other end of the first section 1121 is connected to the second section 1122. Figure 3 As shown, the atomizer assembly 100 further includes a connecting tube 160, which is located in the second section 1122 and connects the first section 1121 and the first accommodating chamber 126. The connecting tube 160 can better connect the first accommodating chamber 126 and the first section 1121, ensuring that the airflow has sufficient speed to push the blocking member 130 and drive atomization.

[0145] In some optional embodiments, the cross-section of the connecting tube 160 gradually decreases toward the nose piece structure 120 .

[0146] Exemplarily, the connecting tube 160 is a cylindrical hollow tube of variable diameter, with the end with a larger diameter fixed to the second section 1122 and the end with a smaller diameter embedded in the first accommodating cavity 126 of the nose support structure 120. When the connecting tube 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.

[0147] like Figure 8As shown, one end of the blocking member 130 has a first groove 134. Figure 6 As shown, a second groove 1261 opposite to the first groove 134 is provided on the left side of the first accommodating cavity 126 , and both 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 .

[0148] See also Figure 8 The other end of the blocking member 130 has an arc-shaped end surface 133, the through hole 1311 is located approximately in the middle of the blocking member 130, and the limiting protrusion 132 is located between the through hole 1311 and the arc-shaped end surface 133. This structure can make the arc-shaped end surface 133 fit the inner wall of the mouth support structure 110, but will not cause the connecting tube 160 to be pushed due to the elastic force when the first elastic member 140 is reset, which is beneficial to protecting the reliability of the installation of the connecting tube 160.

[0149] When the user holds the mouthpiece 112, the nasal opening 1211 is placed in the nasal cavity. When blowing hard, the airflow flows through the first section 1121 of the mouthpiece 112 and the connecting tube 160 in sequence. Because the cross-section of the airflow channel gradually decreases, the airflow speed will gradually increase. A part of the high-speed airflow pushes the blocking member 130 to move left, and the first elastic member 140 is compressed. During the movement of the blocking member 130, the through hole 1311 gradually connects with the fluid channel 124 of the nasal opening structure 120. Under the action of the pressure in the medicine bottle, the liquid in the second chamber 1242 quickly moves up to the first chamber 1241, and after being atomized by the atomization chip 150, it enters the nasal cavity.

[0150] In addition, another portion of the gas moves upward through the auxiliary channel 123 and overflows from both sides of the nasal opening 1211. The auxiliary airflow can not only continue to disperse the atomized droplets, but also accelerate the droplets, increasing the speed at which the aerosol enters the nasal cavity and delivering it deeper into the nasal cavity.

[0151] Example 2

[0152] The following combination Figure 9 and Figure 10 , the container assembly 200 of this embodiment is further introduced in detail.

[0153] The container assembly 200 of the embodiment of the present disclosure is used in connection with the atomizer assembly 100 described in Example 1.

[0154] The container assembly 200 of this embodiment includes all the technical features of the container assembly 200 in Example 1, which will not be described again.

[0155] like Figure 10As shown, the container assembly 200 includes: a tank body 210 and a bag body 220. The bag body 220 is located in the tank body 210. The inner cavity of the bag body 220 is used to contain liquid. There is a separation space 201 between the bag body 220 and the tank body 210. The separation space 201 contains a power source.

[0156] Without limitation, the power source may be compressed gas. Under the pressure of the power source, the liquid in the bag body 220 can enter the fluid channel 124. The atomization power source of the liquid mainly comes from the compressed gas between the bag body 220 and the tank body 210, and the atomization drive mainly comes from the power of the blowing of the mouthpiece 112.

[0157] The container assembly 200 may further include a valve seat 230 , which is connected to the tank body 210 and the bag body 220 , respectively, to seal the partition space 201 .

[0158] The container assembly 200 may further include a valve structure for opening or closing the bag body 220. When the valve structure is in an open state, the power source compresses the bag body 220 to provide a driving force for the injection of the liquid.

[0159] In some optional embodiments, see Figure 10 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, which is connected to 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 keep the one-way valve 250 in a position to close the valve channel 241, so that the valve structure is in a closed state; when the atomizer assembly 100 is connected to the container assembly 200, the atomizer assembly 100 pushes the one-way valve 250 to overcome 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 an open state.

[0160] The one-way valve 250 remains in the closed state under the elastic action of the second elastic member 260. When the atomizer assembly 100 is installed in place, the atomizer assembly 100 pushes the one-way valve 250 to overcome the elastic force of the second elastic member 260, and the one-way valve 250 can be switched from the closed state to the open state.

[0161] The second elastic member 260 is a compression spring or a spring, but is not limited thereto.

[0162] In some optional embodiments, such as Figure 10As shown, the valve channel 241 includes: an upper channel 2411, a lower channel 2413 and a transition channel 2412. The two ends of the transition channel 2412 are connected to the upper channel 2411 and the lower channel 2413 respectively. The inner diameter of the lower channel 2413 is larger than the inner diameter of the upper channel 2411. The inner diameter of the bottom of the transition channel 2412 is larger than the inner diameter of the top of the transition channel 2412. The one-way valve 250 includes: a base 251 and a driving member connected to the base 251. The driving portion 252 has a maximum outer diameter that is larger than the minimum inner diameter of the transition channel 2412, and the outer diameter of the driving portion 252 is smaller than the inner diameter of the upper channel 2411, and is located in the upper channel 2411; when the valve structure is in a 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 an 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.

[0163] "Inner diameter" and "outer diameter" can both be diameters.

[0164] Exemplarily, the driving portion 252 and the base portion 251 are an integral structure, and the one-way valve 250 can be formed by integral molding.

[0165] When the atomizer assembly 100 is connected to the container assembly 200 , the push column 122 of the atomizer assembly 100 docks with the drive portion 252 of the one-way valve 250 . The push column 122 pushes the drive portion 252 downward to open the valve channel 241 .

[0166] The maximum outer diameter of base 251 is larger than the minimum inner diameter of transition channel 2412, preventing base 251 from passing through the minimum inner diameter of transition channel 2412. This serves as a limit on the movement of one-way valve 250. When one-way valve 250, constrained by transition channel 2412, abuts against the inner wall of transition channel 2412, liquid below cannot flow upward. In other words, one-way valve 250 cannot move into upper channel 2411, and valve channel 241 is closed. Because the inner diameter of lower channel 2413 is larger, when push column 122 pushes one-way valve 250 downward, it can move toward lower channel 2413, creating a gap between one-way valve 250 and the inner wall of valve channel 241, opening valve channel 241.

[0167] The second elastic member 260 is compressed or reset as the one-way valve 250 moves up and down.

[0168] from Figure 10 As can be seen in the illustrated implementation, the outer diameter of the base 251 gradually increases from top to bottom, while 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 portion is greater than or equal to the inner diameter of the upper channel 2411, and the one-way valve 250 cannot move into the upper channel 2411.

[0169] In some optional embodiments, such as Figure 10 The valve structure shown further includes a valve core 280 , which is at least partially located below the valve body 240 and connected to the valve body 240 . The valve core 280 has a flow channel 281 , which communicates with the valve channel 241 and the inner cavity of the bag body 220 .

[0170] The valve channel 241 is used for transporting liquids, and the valve body 240 and valve core 280 are placed in the bag body 220. The valve body 240 and valve core 280 are sealed and assembled, 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 one-way valve 250. It is understood that in addition to fixing one end of the second elastic member 260 to the top of the valve core 280, it can also be fixed in other ways. For example, the inner wall of the valve channel 240 of the valve body 240 extends inwardly, and one end of the second elastic member 260 can be fixed to this boss.

[0171] For example, the valve body 240 at least partially protrudes from the tank body 210 , and the top of the valve body 240 can serve as a fixing boss that is plugged into and engaged with the fixing groove 125 of the aforementioned atomizer assembly 100 .

[0172] The valve core 280 is located below the valve body 240. The liquid in the bag body 220 first enters the flow channel 281 and then enters the valve channel 241 through the flow channel 281. The valve core 280 extends the valve channel 241, making it easier for the liquid in the bag body 220 to enter the valve channel 241.

[0173] Continue to refer Figure 10 In some optional 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.

[0174] In some optional embodiments, the container assembly 200 further includes: an upper cover 270 mounted on the valve seat 230 , and a thread for connecting to the atomizer assembly 100 is provided on the outer surface of the upper cover 270 or the valve seat 230 .

[0175] Figure 9 and Figure 10 In the illustrated embodiment, threads are formed on the outer periphery of the upper cover 270, namely external threads 271. The upper cover 270 is positioned above the valve seat 230 and is coaxially and tightly assembled with the valve seat 230, preventing relative rotation. The outer cylindrical surface of the upper cover 270 has external threads 271, which primarily mate with the internal threads 115 at the lower end of the mouthpiece 110 of the atomizer assembly 100.

[0176] In some optional embodiments, such as Figure 9 and Figure 10 As shown, the container assembly 200 further includes a sealing member 290 detachably covering the outlet of the valve structure, wherein the liquid is sprayed out through the outlet of the valve structure.

[0177] The sealing member 290 covers the top of the valve body 240 and can be made of a flexible plastic. When the container assembly 200 is used, the sealing member 290 can be torn off or pierced. The sealing member 290 on the top of the valve body 240 can also be designed as a threaded medicine bottle cap or a plastic bottle cap. When in use, it only needs to be twisted to open or pull off the bottle cap.

[0178] Example 3

[0179] A nasal spray device 300 is characterized in that the nasal spray device 300 includes: the atomizing assembly 100 described in Example 1, and the container assembly 200 described in Example 2.

[0180] The general process of assembling the atomizer assembly 100 and the container assembly 200 includes: first, removing the sealing member 290 at the top of the container assembly 200, placing a flexible sealing gasket (a specific form of the sealing member 400) in the fixing groove 125 at the lower end of the atomizer assembly 100, and then matching it with the fixing groove 125 at the top of the upper cover 270. Then, by rotating downward, the push column 122 at the bottom end of the nose bearing structure 120 pushes the one-way valve 250 in the container assembly 200 downward, and the second elastic member 260 at the lower end is compressed. At this time, the valve channels 241 at the upper and lower ends of the one-way valve 250 are connected. At the same time, the internal thread 115 at the lower end of the mouth bearing structure 110 is adapted to the thread on the outside of the upper cover 270, completing the sealing and fixing of the two components during the rotation process.

[0181] The bag valve container assembly 200 is designed as a replaceable assembly. When the liquid medicine in the container assembly 200 is used up, the two parts of the assembly can be separated by rotating the atomizer assembly 100, and then a new medicine bottle can be replaced. After reassembly, it can continue to be used.

[0182] The general usage process of the nasal spray device 300 includes: an initial state, an atomization process, and a reset process.

[0183] The initial state is shown in Figure 12 and Figure 13As shown, the first elastic member 140 is in a compressed or free state, and the limiting protrusion 132 of the blocking member 130 abuts the inner wall surface of the nose piece structure 120. Under the action of the compressed gas pressure between the tank body 210 and the bag body 220, the liquid in the bag body 220 flows through the flow channel 281, the valve channel 241, and the inlet of the fluid channel 124 in sequence, entering the second chamber 1242 of the fluid channel 124. At this point, the blocking member 130 completely separates the first chamber 1241 and the second chamber 1242, preventing the liquid from entering the upper portion of the atomizer assembly 100.

[0184] See also Figure 15 and Figure 16 , when the user holds the mouthpiece 112, the nasal opening 1211 is placed in the nasal cavity. When blowing hard, the airflow flows through the mouthpiece 112 and the connecting tube 160 in sequence. Because the cross-section of this section of the airflow channel gradually decreases, the airflow speed will gradually increase. A part of the high-speed airflow pushes the blocking member 130 to move left, and the first elastic member 140 is compressed. 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 nasal opening structure 120. Under the action of the pressure in the container assembly 200, the liquid in the second chamber 1242 quickly moves upward, is atomized by the atomization chip 150, and enters the nasal cavity.

[0185] Additionally, another portion of gas enters the auxiliary channel 123 through the first accommodating chamber 126. After moving upward, the airflow overflows from both sides of the nasal opening 1211. This auxiliary airflow not only continues to disperse the atomized droplets, but also accelerates the droplets, increasing the speed at which the aerosol enters the nasal cavity and delivering it deeper into the nasal cavity. This process is called atomization.

[0186] When blowing into mouthpiece 112 stops, the compressed first elastic member 140 releases its elastic force, pushing barrier 130 back into its original position until the outer curved surface of barrier 130 is completely in contact with the lower curved surface of nosepiece 120. During this process, barrier 130 gradually shifts rightward, and the solid portion of barrier 130 gradually separates first chamber 1241 and second chamber 1242 of nosepiece 120, gradually disconnecting fluid passage 124. Once fluid passage 124 is completely disconnected, atomization ceases. This process is called the reset process.

[0187] Under the premise of no conflict, different embodiments or different technical features of the present disclosure can be arbitrarily combined to form new embodiments.

[0188] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations of the claims.
