Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and 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 (upper, middle and lower) and their corresponding upper, middle and lower nasal passages. The inner side is the nasal septum, and the back is the posterior nasal foramen that connects to the pharynx. Conventional nasal devices target drug delivery to the lower nasal space, where the epithelium is not the most suitable for drug absorption, and the possibility of drug clearance is increased due to nasal drip, swallowing or mucociliary clearance, potentially leading to changes in absorption and poor efficacy. Compared with the lower nasal space, the olfactory epithelium in the upper nasal space has non-motile ciliated cells, rich blood vessels and increased permeability, making it an ideal pathway for rapid absorption of drugs into the systemic circulation. In order to ensure the targeted delivery and therapeutic effect of the drug spray through the nasal cavity, it is necessary to reasonably control the parameters such as the spray rate and spray particle size distribution of the nasal spray device.

[0003] In order to deliver 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, the atomizer nozzle is too long and may cause discomfort to patients when using it. Increasing the atomization driving force generally requires adding an additional mouth-blowing form while manually pressing the pumping component to spray the drug, using the airflow from the mouth to assist in increasing the driving force. This requires the coordination of pressing and mouth-blowing, and requires a high level of hand-mouth coordination of the operator. Summary of the invention

This dual-power-driven mode using a power source and airflow can improve the spray rate and spray particle size distribution, and thus enhance the therapeutic effect.

[0093] Example 1

[0094] The atomizer assembly 100 provided in the embodiment of the present disclosure is used in conjunction with the container assembly 200. Fig.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 the container 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 atomizer assembly 100, and finally enters the nasal cavity in an atomized state to achieve nasal administration.

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

[0096] See also Figures 1 to 3 As shown, the atomizer 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 nosepiece structure 120 has a nosepiece opening 1211. During use, the operator uses the mouthpiece 112 to blow air into the nosepiece structure 120, and the atomized droplets are sprayed into the nasal cavity through the nosepiece opening 1211.

[0097] The nose piece structure 120 also includes a fluid channel 124. In order to spray liquid, the nose piece 1211 can at least be connected to the fluid channel 124, so that the liquid in the container assembly 200 can be sprayed toward the nose piece 1211 through the fluid channel 124. The blocking member 130 has at least a locked position and an open position relative to the nose piece 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 atomizer assembly 100 is connected to the container assembly 200 containing liquid, the blocking member 130 is in the locked position, and the liquid has a tendency to flow toward the fluid channel 124 under the driving action of the power source of the container assembly 200; when blowing air to the mouthpiece 112, the airflow formed by the blowing air is used to push the blocking member 130 from the locked position to the open position, so that the liquid is sprayed toward the nose piece 1211 through the fluid channel 124 under the driving action of the power source.

[0098] The nose piece structure 120 also includes an auxiliary channel 123, and the airflow blown in through the mouthpiece 112 can also provide driving force for the injection of the liquid through the auxiliary channel 123. The airflow blown in through the mouthpiece 112 can both assist in accelerating the injection of the liquid and assist in atomizing the liquid. This mode of dual-power drive by the power source and the airflow can improve the spray rate and the distribution of the spray particle size, and enhance the treatment effect.

[0099] 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 driving action of the power source, the fluid has a tendency to spray and is in a state to be sprayed. When blowing air into the mouthpiece 112, the airflow is used to push the blocking member 130 to move to the open position. Under the driving action of the power source in the container assembly 200, the liquid is sprayed toward the nasal opening 1211 through the fluid channel 124. The process of triggering the spraying does not require pressing operation. Only blowing air can open the fluid channel 124 and assist in the spraying of the liquid, which reduces 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. In this way, the atomizer assembly 100 can be reused, and one atomizer assembly 100 can be matched with container assemblies 200 of different doses to achieve the delivery of different doses of drugs, and different container assemblies 200 of the same dose can also be replaced. In order to make the atomizer assembly 100 reusable, the blocking member 130 can be switched between a locked position and an open position relative to the nose bearing structure 120, wherein the atomizer assembly 100 remains in the locked position without airflow.

[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 has a tendency 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 spraying 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 is 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 and fixation between the atomizer assembly 100 and the container assembly 200 are realized, 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 bearing structure 120 includes a nose bearing body 121 and a push column 122, the nose bearing body 121 has a nose bearing opening 1211, a fluid channel 124 and an auxiliary channel 123; the push column 122 is connected to the nose bearing body 121, and 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, so that the valve structure is switched from a closed state to an open state. That is, the valve structure can be opened by connecting the atomizer assembly 100 with the container assembly 200, which is simple to operate.

[0106] The push column 122 and the nose bearing body 121 may be integral parts, and the two may be formed in an integrated manner, which may simplify the nose bearing structure 120. However, the present invention is not limited thereto, for example, the push column 122 may also be a separate structure from the nose bearing body 121, and the push column 122 and the nose bearing body 121 may be connected by means of clamping, 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 is formed as 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 and does not affect 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 outer side of the push column 122. Figure 4 The inlets 1243 of two fluid channels 124 are shown by way of example.

[0108] from Figures 4 to 6 As can be seen from the implementation shown, the push column 122 is disposed protruding downward at the bottom of the nose bearing body 121. The fluid channel 124 is approximately located at the center of the nose bearing structure 120, and the push column 122 and the fluid channel 124 are approximately coaxially distributed. Fig.13 and Fig.15 As shown, the valve channel 241 (described further below) for liquid to pass through in the valve structure is roughly coaxial with the fluid channel 124, where "axis" may refer to the center of the corresponding channel. The valve channel 241 is located at a roughly central position 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. Fig.15 and Fig.16 When in the open position shown in FIG. 1 , 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 as shown in FIG. Fig.12 and Fig.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] Exemplarily, in order 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 is substantially coaxial with the fluid channel 124 .

[0111] In some optional embodiments, such as Figure 6As shown, the nasal bearing 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 divides the fluid channel 124 into a first chamber 1241 and a second chamber 1242, and the first chamber 1241 is connected to the nasal bearing 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 bearing 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 blowing nozzle 112 , so that the airflow blown by the blowing nozzle 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 also includes: a first elastic member 140, one end of the first elastic member 140 is in a fixed state relative to the nose bearing 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] Under the elastic action of the first elastic member 140, the blocking member 130 is kept 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 be switched 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, so that the blocking member 130 can be switched between the locked position and the open position.

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

[0116] Figure 3 and Figure 6 It is exemplarily shown that the first elastic member 140 is a compression spring, the left side of the first accommodating cavity 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 cavity 126 and the left end of the blocking member 130, and the right side opening of the first accommodating cavity 126 is connected to the nozzle 112.

[0117] In some optional embodiments, combined with Fig.13 and Fig.14 As shown, when the blocking member 130 is in the locked position, the blocking member 130 also closes the auxiliary channel 123; Figure 16 to Figure 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] Combination 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. Fig.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 in FIG. Fig.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 Fig.17 The entrance of the auxiliary channel 123 is located above the first accommodating chamber 126, and the auxiliary channel 123 and the limiting groove 127 are both connected to the first accommodating chamber 126. The entrance of the auxiliary channel 123 can be one, two, three or more. When the blocking member 130 is in the locked position, the entity part of the blocking member 130 blocks the fluid channel 124 and the auxiliary channel 123 at the same time, and the external fluid cannot enter 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 assist 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 site.

[0123] See also Figure 3 The atomizer assembly 100 is inclined from top to bottom at the fluid outlet (including the nasal socket 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 targeted 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 bearing structure 120 , and the fixing groove 125 can be plugged and matched with the fixing boss of the container assembly 200 , thereby improving the reliability of the connection between the nose bearing structure 120 and the container assembly 200 .

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

[0126] In some alternative embodiments, see Fig.13 The atomizer assembly 100 further includes a seal 400, which is located in the fixing groove 125 to seal the nose piece 120 with the container assembly 200. After the atomizer 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 boss to prevent the liquid in the container assembly 200 from leaking through the connection between the nose piece 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 is 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 bearing structure 120 . The fixed chamber 1244 is located in the fluid channel 124 and between the nose bearing opening 1211 and the first accommodating chamber 126 . There is no relative movement or rotation between the atomizer chip 150 and the nose bearing structure 120 .

[0132] In some optional embodiments, such as Figure 7 As shown, the mouthpiece structure 110 also includes: a mouthpiece body 111, the mouthpiece body 111 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 communicated with the nosepiece opening 1211, and the 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 by one-piece molding.

[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 injection 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 port 1211 is aligned with the injection 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 air, so that one component has multiple uses.

[0138] In some optional embodiments, the mouthpiece body 111 is provided with threads. Figure 7 The thread of the mouthpiece body 111 is exemplarily shown as an internal thread 115. The mouthpiece body 111 is threadedly assembled and connected with the container assembly 200. The mouthpiece structure 110 is also used to connect the container assembly 200 to achieve 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, and the nosepiece fixing plate 114 has a mounting hole 1141, as shown in FIG. Figure 3As shown, the nose support structure 120 is inserted into 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 bearing structure 120 gradually increases from the nose bearing fixing 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, its outer diameter gradually increases downward and cannot completely pass through the mounting hole 1141, so that the nose bearing fixing plate 114 plays a role in fixing the nose bearing structure 120. This method does not require the use of additional fixing parts to fix the two, and can achieve the installation and removal of the nose bearing structure 120 and the mouth bearing structure 110 without tools, which is 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 respectively 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 to ensure 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 support 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 bearing structure 120. When the connecting tube 160 is assembled with the nose bearing structure 120 and the oral bearing structure 110, the surfaces are completely fitted without any 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 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 .

[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 bearing structure 110, but the connecting tube 160 will not 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 socket 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 socket structure 120, and the liquid in the second chamber 1242 moves rapidly upward to the first chamber 1241 under the action of the pressure in the medicine bottle, and enters the nasal cavity after being atomized by the atomization chip 150.

[0150] In addition, another part of the gas moves upward through the auxiliary channel 123 and overflows from both sides of the nasal opening 1211. The auxiliary airflow can continue to disperse the atomized droplets on the one hand, and accelerate the droplets on the other hand, so that the speed of the atomized aerosol entering the nasal cavity is increased and delivered to deeper parts of the nasal cavity.

[0151] Example 2

[0152] Combine the following Fig. 9 and Fig.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 Embodiment 1, which will not be described again.

[0155] like Fig.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 may enter the fluid channel 124, and 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 blowing from the mouthpiece 112.

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

[0158] The container assembly 200 may further include a valve structure, which is used to open or close 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 Fig.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, and the valve channel 241 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 is kept 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 sheet, but is not limited thereto.

[0162] In some optional embodiments, such as Fig.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, and 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 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 is docked with the drive portion 252 of the one-way valve 250 , and the push column 122 pushes the drive portion 252 to move downward to open the valve channel 241 .

[0166] The maximum outer diameter of the base 251 is greater than the minimum inner diameter of the transition channel 2412, and the base 251 cannot pass through the minimum inner diameter of the transition channel 2412, which limits the movement of the one-way valve 250. Under the limiting effect of the transition channel 2412, when the one-way valve 250 is in contact with the inner wall of the transition channel 2412, the liquid below cannot flow upward, that is, the one-way valve 250 cannot move into the upper channel 2411, and at this time, the valve channel 241 is closed. Since the inner diameter of the lower channel 2413 is larger, when the push column 122 pushes the one-way valve 250 downward, the one-way valve 250 can move toward the lower channel 2413, and a gap is generated between the one-way valve 250 and the inner wall of the valve channel 241, and the valve channel 241 is opened.

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

[0168] from Fig.10 It can be seen from the implementation shown that the outer diameter of the base 251 increases gradually from top to bottom, and the inner diameter of the transition channel 2412 increases gradually from top to bottom. The outer diameter of the base 251 at the middle position 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 Fig.10 The valve structure shown also 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 is connected to the valve channel 241 and the inner cavity of the bag body 220 respectively.

[0170] The valve channel 241 is used for transporting liquids, and the valve body 240 and the valve core 280 are placed in the bag body 220. The valve body 240 and the 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 can be understood that in addition to being fixed to the top of the valve core 280, one end of the second elastic member 260 can also be fixed in other ways, such as: the inner wall of the valve channel 240 of the valve body 240 extends inwardly to form a boss, and one end of the second elastic member 260 can be fixed on the boss.

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

[0172] The valve core 280 is located below the valve body 240, and the liquid in the bag body 220 first enters the flow channel 281, and then enters the valve channel 241 from 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 Fig.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 the upper cover 270 or the valve seat 230 is provided with threads for connecting to the atomization assembly 100 .

[0175] Fig. 9 and Fig.10 In the implementation shown, threads are formed on the outer periphery of the upper cover 270, namely, external threads 271. The upper cover 270 is located on the upper part of the valve seat 230, and is coaxially sealed and assembled with the valve seat 230 without relative rotation. The outer cylindrical surface of the upper cover 270 has external threads 271, which are mainly used for assembly with the internal threads 115 at the lower end of the mouth bearing structure 110 of the atomizer assembly 100.

[0176] In some optional embodiments, such as Fig. 9 and Fig.10 As shown, the container assembly 200 further includes: a sealing member 290, which is detachably covered on 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 the material can be 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, and when in use, it only needs to be twisted to unscrew or pull off the bottle cap.

[0178] Example 3

[0179] A nasal spray device 300, characterized in that the nasal spray device 300 comprises: the atomization 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, remove the sealing member 290 at the top of the container assembly 200, place 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 match 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 outer side of the upper cover 270, and the sealing and fixing of the two components are completed 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 replaced with a new medicine bottle, and then reassembled for continued use.

[0182] The general use 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 Fig.12 and Fig.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 against the inner wall surface of the nose bearing 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 entrance of the fluid channel 124 in sequence, 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, and the liquid cannot enter the upper part of the atomizer assembly 100.

[0184] See also Fig.15 and Fig.16 , when the user holds the mouthpiece 112, the nasal socket 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 communicates with the first chamber 1241 and the second chamber 1242 of the nasal socket structure 120. Under the action of the pressure in the container assembly 200, the liquid in the second chamber 1242 quickly moves upward, and after being atomized by the atomization chip 150, it enters the nasal cavity.

[0185] In addition, another part of the gas enters the auxiliary channel 123 through the first accommodating cavity 126, and after the airflow moves upward, it overflows from both sides of the nasal opening 1211. The auxiliary airflow can continue to disperse the atomized droplets on the one hand, and accelerate the droplets on the other hand, so that the speed of the atomized aerosol entering the nasal cavity is increased and delivered to a deeper part of the nasal cavity. This process is the atomization process.

[0186] When blowing into the mouthpiece 112 stops, the compressed first elastic member 140 releases its elastic force, pushing the blocking member 130 to reset until the outer edge arc surface of the blocking member 130 is completely in contact with the lower end outer arc surface of the nose bearing structure 120.
