Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an integrated atomization component and an atomizer having the same. Background Art

[0002] Nebulizers can convert liquid drugs into aerosols of tiny particles, allowing the drugs to act directly on the patient's respiratory tract and lungs through breathing, thereby moistening the airways, diluting sputum, relieving coughs and asthma, and are widely used in the prevention and auxiliary treatment of respiratory diseases.

[0003] Currently, a nebulizer typically consists of a main unit, a drug cup unit, a nebulizer unit, an air inlet check valve, a spacer, a mouthpiece, and a respiratory mask. When the user inhales through the mouthpiece or respiratory mask, the air inlet check valve opens, allowing the liquid drug in the drug cup unit to pass through the nebulizer unit, forming tiny particles that enter the patient's respiratory tract through the spacer. Conversely, when the user exhales, the air inlet check valve closes, preventing drug exhalation with the exhaled air, improving drug delivery efficiency, and preventing backflow of air that could cause biocontamination and drug waste.

[0004] During use, some medication inevitably remains in components such as the drug cup unit, air inlet check valve, and spacer. If not cleaned promptly, bacteria can easily grow, affecting the effectiveness of the next nebulizer treatment. However, existing nebulizer components such as the drug cup unit, air inlet check valve, and spacer are typically fixed and difficult to disassemble, making them difficult to clean promptly and effectively, significantly limiting their reliability during repeated use.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0006] In order to solve or to some extent improve the technical problem of the difficulty in disassembling the components of the nebulizer in the prior art, the present invention provides an integrated nebulizer assembly. The integrated nebulizer assembly includes: a mist storage tank having a mist inlet and a mist outlet relative to each other; an air inlet one-way valve connected to the mist storage tank and arranged at the mist inlet to control the opening and closing of the mist inlet; and a liquid medicine cup, the liquid medicine cup being located on a side of the air inlet one-way valve away from the mist inlet, and the liquid medicine cup being rotatably arranged on the mist storage tank so that the liquid medicine cup can be switched between a fixed position in which it is fixedly connected to the mist storage tank and a movable position in which it is separated from the mist storage tank, wherein when the liquid medicine cup is in the fixed position, the air inlet one-way valve forms a sealed connection with the mist storage tank.

[0007] Those skilled in the art will appreciate that the integrated atomization assembly of the present invention includes a spacer, an air inlet check valve, and a medicine liquid cup. The spacer has opposing mist inlet and mist outlet ports. The air inlet check valve is connected to the spacer and positioned at the spacer's mist inlet to control the opening and closing of the mist inlet. The medicine liquid cup is positioned on the side of the air inlet check valve away from the mist inlet. Furthermore, the medicine liquid cup is rotatably mounted on the spacer and has a fixed position in which it is fixedly connected to the spacer and a movable position in which it is separated from the spacer. When the medicine liquid cup is in the fixed position, the medicine liquid cup and the spacer form a fixed connection, and the air inlet check valve is constrained between the medicine liquid cup and the spacer, enabling the entire integrated atomization assembly to interact with other components (e.g., a main unit, atomizer unit, etc.) to convert liquid medicine into aerosol. Furthermore, when the medicine liquid cup is in the fixed position, the air inlet check valve also forms a sealed connection with the spacer to prevent leakage of aerosol within the spacer. Accordingly, when the liquid medicine cup is in the active position, the liquid medicine cup and the spacer are separated from each other, and the liquid medicine cup can rotate relative to the spacer, thereby exposing the space between the liquid medicine cup and the air inlet check valve. This facilitates timely and effective cleaning of components such as the liquid medicine cup, the air inlet check valve, and the spacer, preventing bacterial growth due to drug residue, and significantly improving the feasibility and reliability of the integrated atomizer assembly of the present invention for reuse. In addition, because the liquid medicine cup, the air inlet check valve, and the spacer are all integrated together, the integrated atomizer assembly of the present invention has a high degree of integration, is easy to store, reduces the risk of component loss, and improves the user experience.

[0008] In the preferred technical solution of the integrated atomizer assembly, the air inlet check valve is rotatably disposed on the spacer. This rotatable arrangement of the air inlet check valve on the spacer conveniently exposes the space between the air inlet check valve and the spacer, thereby improving cleaning of the air inlet check valve and the spacer.

[0009] In the preferred technical solution of the above integrated atomizer assembly, the air inlet check valve has the same rotation axis as the liquid medicine cup. The air inlet check valve and the liquid medicine cup both use the same rotation axis, which can also improve the structural stability of the integrated atomizer assembly.

[0010] In the preferred technical solution of the above-mentioned integrated atomization assembly, the liquid medicine cup includes: a circumferential ring wall, the circumferential ring wall being rotatably arranged on the spacer; and a mounting plate, the mounting plate being arranged inside the circumferential ring wall and extending radially along the circumferential ring wall. When the liquid medicine cup is in a fixed position, the mounting plate, the circumferential ring wall, and the air inlet check valve together form a fixed cavity suitable for accommodating the atomizer unit. This arrangement allows the atomizer unit to be conveniently and stably fixed between the mounting plate and the air inlet check valve.

[0011] In a preferred embodiment of the integrated atomizer assembly, a main air inlet is defined in the circumferential wall on a side of the mounting plate away from the air inlet check valve, and air guide holes are defined in the mounting plate, allowing external air to enter the spacer through the main air inlet, the air guide holes, and the air inlet check valve in sequence. This arrangement allows external air to smoothly enter the spacer through the main air inlet, the air guide holes, and the air inlet check valve, thereby driving the aerosolized drug particles to form an aerosol.

[0012] In a preferred embodiment of the integrated atomizer assembly, an auxiliary air inlet hole is provided on the side of the circumferential wall, located on the mounting plate near the air inlet check valve, allowing external air to enter the spacer through the auxiliary air inlet hole and the air inlet check valve. The provision of the auxiliary air inlet hole increases the amount of air entering the spacer, thereby improving drug delivery efficiency.

[0013] In the preferred technical solution of the above-mentioned integrated atomization assembly, a liquid outlet is also provided on the mounting plate; the liquid medicine cup also includes a liquid storage cup arranged on a side of the mounting plate away from the air inlet one-way valve, and the liquid storage cup has a liquid inlet connected to the liquid outlet; and a central through hole for connecting the liquid outlet and the mist inlet is provided on the air inlet one-way valve. The provision of the liquid storage cup facilitates the accommodation of liquid medicine. In addition, the provision of the liquid outlet on the mounting plate and the provision of the central through hole on the air inlet one-way valve can provide a suitable flow path for the medicine.

[0014] In a preferred embodiment of the integrated atomizer assembly, the liquid storage cup includes a curved plate connected to the mounting plate. The curved plate and the mounting plate together define a hollow liquid storage chamber, and the cross-section of the liquid storage chamber gradually decreases in a vertically downward direction. This arrangement allows the liquid medication to flow smoothly under its own gravity, reducing medication residue.

[0015] In the preferred technical solution of the above-mentioned integrated atomization assembly, the bottom of the liquid storage chamber is flush with the bottom of the liquid outlet to further reduce drug residue.

[0016] In the preferred technical solution of the above-mentioned integrated atomization assembly, the medicine liquid cup further comprises a cup cover capable of opening and closing the liquid inlet. The arrangement of the cup cover can conveniently open or close the liquid inlet.

[0017] In a preferred embodiment of the integrated atomizer assembly, the spacer is provided with a connecting shaft proximate the mist inlet, and a first bearing is provided on the circumferential wall, rotatably disposed on the connecting shaft. This arrangement facilitates the rotation of the liquid medicine cup relative to the spacer.

[0018] In the preferred technical solution of the integrated atomizer assembly, the spacer is provided with a latching protrusion located on the side of the mist inlet, away from the connecting shaft. The liquid medicine cup also includes a connecting tongue connected to the circumferential ring wall, and the connecting tongue is provided with a latching hole that engages with the latching protrusion. The provision of the latching hole and latching protrusion facilitates a removable connection between the liquid medicine cup and the spacer, enabling the liquid medicine cup to be switched between a fixed position and a movable position.

[0019] In the preferred technical solution of the above-mentioned integrated atomizer assembly, the connecting tongue is configured to extend obliquely from the circumferential ring wall toward the spacer tank and away from the spacer tank. The obliquely arranged connecting tongue enables the snap-fit protrusion to be easily inserted into the snap-fit hole.

[0020] In the preferred technical solution of the above-mentioned integrated atomization assembly, the spacer includes a first cylindrical section, a conical section, and a second cylindrical section connected in sequence, the cross-section of the conical section gradually decreasing along the direction from the first cylindrical section to the second cylindrical section, wherein the mist inlet is located in the first cylindrical section, the mist outlet is located in the second cylindrical section, and the connecting shaft and the engaging protrusion are both arranged on the first cylindrical section. Through the above-mentioned arrangement, the mist inlet has a larger area to facilitate aerosol collection, while the mist outlet has a smaller area to facilitate mouth-to-mouth breathing by the user.

[0021] In the preferred technical solution of the above-mentioned integrated atomization assembly, the air inlet one-way valve includes: a grid plate, the grid plate is rotatably arranged on the mist storage tank; a valve, the valve is arranged on the side of the grid plate close to the mist inlet; and a pressure block, the pressure block is arranged on the side of the valve away from the grid plate and is configured to detachably fix the valve on the grid plate, wherein the central through hole includes a first central through hole, a second central through hole and a third central through hole respectively arranged on the grid plate, the valve and the pressure block. Through the above-mentioned arrangement, the air inlet one-way valve has a simple and reliable structure.

[0022] In the preferred technical solution of the integrated atomizer assembly, when the liquid medicine cup is in the fixed position, the liquid outlet, the first central through hole, the second central through hole, the third central through hole, and the mist inlet have the same or parallel center lines. This arrangement allows the liquid outlet, the first central through hole, the second central through hole, the third central through hole, and the mist inlet to form a suitable flow path, facilitating the flow of liquid medicine.

[0023] In the preferred technical solution of the above-mentioned integrated atomizer assembly, the diameters of the second central through hole and the third central through hole are both greater than or equal to the diameter of the first central through hole, so that the liquid medicine has less resistance when passing through the air inlet one-way valve.

[0024] In the preferred technical solution of the above-mentioned integrated atomization assembly, a plurality of vents spaced apart from each other are provided on the grid plate surrounding the first central through hole; a valve body corresponding to each of the vents is provided on the valve; and a pressing column corresponding to each of the valve bodies is provided on the pressure block, and each of the pressing columns abuts against one side of the corresponding valve body. When the user inhales, the pressure on the side of the valve body close to the grid plate is greater than the pressure on the side close to the pressure block, causing the valve body to deform, thereby opening the vent. Correspondingly, when the user exhales, the pressure on the side of the valve body close to the pressure block is greater than the pressure on the side close to the grid plate, and the valve body will fit tightly against the grid plate, thereby closing the vent. Furthermore, since the pressing column abuts against one side of the corresponding valve body, the deformation of the valve body close to the pressing column is smaller, while the deformation of the valve body away from the pressing column is larger. In this way, on the one hand, irregular deformation of the entire valve body can be avoided, the reliability of the valve body's sealing vents can be increased, and the risk of air flow backflow can be reduced accordingly; on the other hand, the air inlet channel at the valve body with larger deformation is larger, while the air inlet channel at the valve body with smaller deformation is smaller, resulting in a spiral airflow when the airflow flows through this tilted valve body, thereby improving the drug delivery efficiency.

[0025] In the preferred technical solution of the above-mentioned integrated atomization assembly, the area of each valve body is greater than or equal to the area of the corresponding vent hole, so that the valve body can effectively block the corresponding vent hole.

[0026] In a preferred technical solution of the above-mentioned integrated atomizer assembly, the grid plate is provided with a plurality of circumferential mounting holes spaced circumferentially around the first central through hole, the circumferential mounting holes being radially located between the first central through hole and the vent hole; the valve is provided with a circumferential through hole corresponding one-to-one to each of the circumferential mounting holes; and the pressure block is provided with mounting blocks that can extend through the corresponding circumferential through holes and form a snap fit with the corresponding circumferential mounting holes. Through the above-mentioned arrangement, the pressure block can conveniently and effectively secure the valve to the grid plate.

[0027] In the preferred technical solution of the integrated atomizer assembly, a sealing ring is formed on the circumferential edge of the grid plate to form a sealed connection with the mist inlet. The provision of the sealing ring facilitates a sealed connection between the grid plate and the spacer, preventing aerosol leakage from the mist inlet.

[0028] In a preferred embodiment of the integrated atomizer assembly, the spacer is provided with a connecting shaft proximate the mist inlet, and the grid is provided with a second bearing rotatably disposed on the connecting shaft. This arrangement facilitates the rotation of the air inlet check valve relative to the spacer.

[0070] Figure 1 1 is a first structural schematic diagram of an embodiment of an integrated atomization assembly of the present invention; Figure 2 2 is a second structural schematic diagram of an embodiment of an integrated atomization assembly of the present invention; Figure 3 Schematic diagram of the exploded structure of an embodiment of the integrated atomizing assembly of the present invention; Figure 4 This is a structural schematic diagram of an embodiment of the integrated atomization assembly of the present invention in which the medicine liquid cup is in a fixed position; Figure 5 Schematic diagram of the structure of the embodiment of the integrated atomization assembly of the present invention in which the liquid medicine cup is in the active position. Figure 1-Figure 5 As shown, in one or more embodiments, the integrated atomization assembly 10 of the present invention includes a spacer 13, an air inlet check valve 12, and a liquid medicine cup 11. The air inlet check valve 12 is connected to the spacer 13; the liquid medicine cup 11 is rotatably arranged on the spacer, and the liquid medicine cup 11 has a fixed position for forming a fixed connection with the spacer 13 (see Figure 4 ) and the active position separated from the spacer 13 (see Figure 5 ).

[0071] like Figure 1-Figure 5As shown, in one or more embodiments, the spacer 13 has opposing mist inlet 1311 and mist outlet 1331. In one or more embodiments, the spacer 13 includes a first cylindrical section 131, a tapered section 132, and a second cylindrical section 133, which are sequentially connected. The first cylindrical section 131 has a generally square cross-section with rounded corners (i.e., a cross-section perpendicular to the axis of the first cylindrical section 131). Alternatively, the first cylindrical section 131 may be configured with other suitable cross-sections, such as a circular shape. The second cylindrical section 133 has a generally circular cross-section (i.e., a cross-section perpendicular to the axis of the second cylindrical section 133). The cross-section of the tapered section 132 (i.e., a cross-section perpendicular to the axis of the tapered section 132) gradually decreases from the first cylindrical section 131 to the second cylindrical section 133. Furthermore, the mist inlet 1311 is located in the first cylindrical section 131, while the mist outlet 1331 is located in the second cylindrical section 133. This allows the mist inlet 1311 to have a larger area, facilitating aerosol collection, while simultaneously allowing the mist outlet 1331 to have a smaller area, facilitating connection to components such as a breathing mask or mouthpiece. It should be noted that the axial center of the first cylindrical section 131 of the spacer 13 is the mist inlet location, and the movable side of the valve 122 of the inlet check valve 12 is evenly distributed near the inner wall of the first cylindrical section 131. When the user inhales, airflow pushes open the valve 122 and enters the spacer 13, flowing along the inner wall. This effectively reduces the time the aerosol remains in contact with the inner wall and reduces the likelihood of aerosol deposition on the inner wall. Furthermore, between the second cylindrical section 133 and the first cylindrical section 131, the diameter gradually decreases away from the first cylindrical section 131 to form a tapered section 132, ultimately connecting to the mist outlet 1331. This design aligns with fluid flow path design principles, avoids airflow reflections caused by direct diameter changes, and effectively reduces aerosol transmission losses.

[0072] Continue to see Figure 3 and Figure 5 In one or more embodiments, a connecting shaft 1312 is provided on the spacer 13 near the mist inlet 1311, so that the medicine cup 11 can be conveniently pivotally connected to the spacer 13 through the connecting shaft 1312. In one or more embodiments, the connecting shaft 1312 is arranged on the first cylindrical section 131. Specifically, based on Figure 3 In the illustrated orientation, the connecting shaft 1312 is disposed on the lower side of the first cylindrical section 131 and extends substantially in the left-right direction. Therefore, in the assembled state, the drug liquid cup 11 can rotate relative to the spacer 13 about a rotation axis extending substantially in the left-right direction.

[0073] Continue to see Figure 3 and Figure 5In one or more embodiments, a snap-in protrusion 1313 is provided on the spacer 13, located on the side of the mist inlet 1311 away from the connecting shaft 1312. The snap-in protrusion 1313 is configured to form a snap-fitting engagement with the snap-in hole 1161 on the connecting tongue 116 on the medicine liquid cup 11, so that the medicine liquid cup 11 can be detachably fixed to the spacer 13. In one or more embodiments, the snap-in protrusion 1313 is also arranged on the first cylindrical section 131 of the spacer 13. Specifically, based on Figure 3 In the orientation shown, the engaging protrusion 1313 is arranged on the upper side of the first cylindrical section 131. The engaging protrusion 1313 extends vertically upward from the upper surface of the first cylindrical section 131. Figure 4 When the clamping protrusion 1313 is inserted into the clamping hole 1161 on the connecting tongue 116, the liquid medicine cup 11 and the spacer 13 are fixedly connected. At this time, the liquid medicine cup 11 is in a fixed position. Figure 5 When the engaging protrusion 1313 is disengaged from the engaging hole 1161, the medicine liquid cup 11 is separated from the spacer 13, and the medicine liquid cup 11 can freely rotate around the connecting shaft 1312. At this time, the medicine liquid cup 11 is in the active position.

[0074] like Figure 1-Figure 5 As shown, the air inlet one-way valve 12 is arranged at the mist inlet 1311 of the mist storage tank 13 to control the opening and closing of the mist inlet 1311. In one or more embodiments, the air inlet one-way valve 12 is rotatably arranged on the mist storage tank 13. Furthermore, the air inlet one-way valve 12 has the same rotation axis as the medicine liquid cup 11. That is, the air inlet one-way valve 12 and the medicine liquid cup 11 can be rotatably arranged on the mist storage tank 13, which not only can conveniently expose the space between the air inlet one-way valve 12 and the mist storage tank 13, thereby better cleaning the air inlet one-way valve 12 and the mist storage tank 13, but also can improve the structural stability of the entire integrated atomization assembly 10. Alternatively, the rotation axis of the air inlet one-way valve 12 and the rotation axis of the medicine liquid cup 11 are spaced apart from each other, that is, the two have different rotation axes.

[0075] Figure 6 Schematic diagram of the structure of an embodiment of the air intake one-way valve in the integrated atomizing assembly of the present invention. Figure 3 、 Figure 5 and Figure 6 As shown, in one or more embodiments, the air inlet check valve 12 includes a grid plate 121, a valve 122, a pressure block 123 and other components. The grid plate 121 is rotatably arranged on the mist storage tank 13. The valve 122 is arranged on one side of the grid plate 121 close to the mist inlet 1311. Figure 3 In the illustrated orientation, the valve 122 is disposed on the front side of the grid plate 121. The pressure block 123 is disposed on the side of the valve 122 away from the grid plate 121 (ie, located on the front side of the valve 122) and is configured to detachably fix the valve 122 to the grid plate 121.

[0076] Continue to see Figure 3 and Figure 6 In one or more embodiments, the grid plate 121 has a substantially square grid plate body with rounded corners. Alternatively, the grid plate body can be configured as a square, a circle, or other suitable shapes. The grid plate body can be made of PC, PP, or other suitable resin materials through an injection molding process. A substantially circular first central through hole 1211 is formed in the middle of the grid plate body. Figure 5 In one or more embodiments, a sealing ring 1215 is further provided on the grid body, and the sealing ring 1215 is along the circumferential edge of the first central through hole 1211 and faces away from the valve 122 (based on Figure 3 In the assembled state, the sealing ring 1215 can be pressed against the atomizing sheet unit 30 so as to form a reliable sealing connection with the atomizing sheet unit 30.

[0077] Continue to see Figure 6 In one or more embodiments, four vents 1212 spaced apart from each other are provided on the grid body. Each vent 1212 has a roughly "L" shape. Alternatively, the vents 1212 may be provided in other suitable shapes, such as circular, square, etc. Alternatively, the vents 1212 may be provided in other suitable numbers more or less than four, such as three, five, etc. Preferably, the four vents 1212 are of the same shape and size, which not only facilitates processing, but also further improves the uniformity of the force applied to the valve 122. In one or more embodiments, the four vents 1212 are evenly spaced along the circumference of the first central through hole 1211, so that the valve 122 opposite to the grid body is evenly stressed and the structure is more stable.

[0078] Continue to see Figure 6 In one or more embodiments, a circumferential protrusion 1213 is formed on each vent 1212. The circumferential protrusion 1213 extends along the circumferential edge of the vent 1212 and toward the corresponding valve body 1224. Therefore, in the assembled state, the valve body 1224 can directly abut against the circumferential protrusion 1213, reducing the contact area between the valve body 1224 and the grid body, ensuring that the valve body 1224 effectively seals the vent 1212.

[0079] Continue to see Figure 6In one or more embodiments, four circumferential mounting holes 1214 spaced apart from each other are provided on the grid plate body. The four circumferential mounting holes 1214 are spaced apart along the circumference of the first central through hole 1211. Furthermore, the four circumferential mounting holes 1214 are evenly spaced apart along the circumference of the first central through hole 1211. Each circumferential mounting hole 1214 is radially located between the first central through hole 1211 and the vent hole 1212. Each circumferential mounting hole 1214 has a generally arcuate shape. Each circumferential mounting hole 1214 can form a snap fit with a corresponding mounting block 1232 on the pressure block 123 to fix the valve 122 on the grid plate 121. It should be noted that the number, shape, and arrangement of the circumferential mounting holes 1214 can also be adjusted according to actual needs, which will not be described in detail here.

[0080] Continue to see Figure 6 In one or more embodiments, a sealing ring 1216 is further provided on the circumferential edge of the grid body. The sealing ring 1216 can be made of TPE, silicone, TPU or other suitable flexible materials. The sealing ring 1216 and the grid body can be processed by two-color injection molding, overmolding or other suitable processes. The provision of the sealing ring 1216 can enhance the sealing performance between the grid 121 and the medicine liquid cup 11 and the mist storage tank 13. In one or more embodiments, a groove (not marked in the figure) that can match the tank mouth of the mist storage tank 13 is further provided on the side of the sealing ring 1216 close to the valve 122 to further improve the sealing performance.

[0081] Continue to see Figure 6 In one or more embodiments, four spaced-apart reinforcing ribs 1217 are further provided on the grid body. Each reinforcing rib 1217 extends from the sealing ring 1216 in a direction toward the first central through hole 1211. The provision of the reinforcing ribs 1217 enhances the structural stability of the sealing ring 1216, preventing severe deformation of the sealing ring 1216 that could compromise sealing performance. Furthermore, the reinforcing ribs 1217 further improve the mechanical strength and structural stability of the entire grid body.

[0082] Continue to see Figure 6 In one or more embodiments, a second bearing 1218 is provided on the grid body and is rotatably arranged on the connecting shaft 1312, so that the entire air intake check valve 12 can be easily rotated relative to the spacer 13. In this way, when the liquid medicine cup 11 is in the active position, the air intake check valve 12 can be rotated to expose the space between the air intake check valve 12 and the spacer 13, thereby facilitating disassembly and cleaning.

[0083] like Figure 6As shown, in one or more embodiments, four valve bodies 1224 spaced apart from each other are provided on the valve 122. Each valve body 1224 corresponds to the vent 1212 one by one. Preferably, the area of each valve body 1224 is greater than or equal to the area of the corresponding vent 1212. In this way, the valve body 1224 can conveniently cover the corresponding vent 1212, ensuring that the airflow does not flow back to the vent 1212 through the gap between the valve body 1224 and the grid body. In one or more embodiments, each valve body 1224 has a roughly fan-shaped shape. Preferably, the shape and size of the four valve bodies 1224 are the same, which not only facilitates processing, but also further improves the uniformity of force on the entire valve 122. It should be noted that the number, shape and size of the valve bodies 1224 can also be adjusted according to actual needs, which will not be repeated here.

[0084] Continue to see Figure 6 In one or more embodiments, the valve 122 further includes a generally annular retaining ring 1221. Four valve bodies 1224 are spaced apart from one another along the circumference of the retaining ring 1221. Furthermore, the four valve bodies 1224 are evenly spaced apart along the circumference of the retaining ring 1221. The retaining ring 1221 and the valve bodies 1224 can be integrally molded from a suitable flexible material, such as silicone, rubber, TPE, or TPU. The thickness of the retaining ring 1221 is greater than that of the valve bodies 1224 to enhance the structural stability of the entire valve 122. In one or more embodiments, a second central through hole 1222 is provided in the middle of the retaining ring 1221, having the same centerline C as the first central through hole 1211. Alternatively, the centerline of the second central through hole 1222 can be parallel to the centerline of the first central through hole 1211. In one or more embodiments, the diameter of the second central through hole 1222 is greater than or equal to the diameter of the first central through hole 1211. In one or more embodiments, the fixing ring 1221 is further provided with four circumferential through holes 1223 spaced circumferentially around the second central through hole 1222. In the assembled state, each circumferential through hole 1223 corresponds one-to-one with a circumferential mounting hole 1214 on the grid plate 121, allowing the corresponding mounting block 1232 on the pressure block 123 to extend through the circumferential through hole 1223 and be secured in the circumferential mounting hole 1214. It should be noted that the number, shape, and arrangement of the circumferential through holes 1223 can be adjusted according to actual needs, as long as they are compatible with the circumferential mounting holes 1214 and the mounting blocks 1232.

[0085] Continue to see Figure 6In one or more embodiments, the pressing block 123 has a roughly circular pressing block body. A third central through hole 1231 is provided in the middle of the pressing block body. The third central through hole 1231 has the same center line C as the first central through hole 1211 and the second central through hole 1222. Therefore, in the assembled state, the first central through hole 1211, the second central through hole 1222 and the third central through hole 1231 can together form a straight flow channel, which facilitates the flow of the tiny particle liquid medicine. Alternatively, the center line of the third central through hole 1231 can also be parallel to the center lines of the first central through hole 1211 and the second central through hole 1222. In one or more embodiments, the diameter of the third central through hole 1231 is also greater than or equal to the diameter of the first central through hole 1211, so that the tiny particle liquid medicine has less resistance when flowing through the entire intake check valve 12, ensuring its smooth flow.

[0086] Continuing with reference to Figure 6, in one or more embodiments, four compression posts 1233 are formed on the compression block body, spaced apart from one another along the circumference of the compression block body. Each compression post 1233 corresponds to a valve body 1224, and each compression post 1233 abuts against one side of the corresponding valve body 1224. Therefore, when the pressure on the valve body 1224 on the grid plate 121 side is greater than the pressure on the compression block 123 side, the valve body 1224 will deform, wherein the valve body 1224 away from the compression posts 1233 will experience a greater deformation, while the valve body 1224 close to the compression posts 1233 will experience a smaller deformation. In this way, not only can the entire valve body 1224 be prevented from experiencing irregular deformation, the reliability of the valve body 1224 in sealing the vent 1212 is increased, and the risk of airflow backflow is correspondingly reduced, but the airflow will also generate a spiral airflow when flowing through such an inclined valve body 1224, preventing the aerosol from contacting the inner wall of the spacer 13 for a long time and depositing, thereby improving the aerosol delivery efficiency. In one or more embodiments, each compression post 1233 is arranged on the same side of the corresponding valve body 1224, so that the force applied to the multiple valve bodies 1224 is more uniform. It should be noted that the compression posts 1233 can also be set to other suitable numbers more or less than four, such as three, five, etc., as long as they can match the valve body 1224.

[0087] Continuing to refer to 6, in one or more embodiments, each compression column 1233 has a compression column body (not shown in the figure) extending straight outward from the circumferential edge of the compression block body. The compression column body and the compression block body are roughly in the same plane. Each compression column body is parallel to a straight line passing through the center of the third center through hole 1231 and is spaced a certain distance apart. A stop rib (not shown in the figure) is also provided on each compression column body. The stop rib extends vertically outward from the compression column body. In the assembled state, the compression column body, the stop rib and the corresponding circumferential protrusion 1213 on the grid plate 121 together form a limiting groove (not shown in the figure) that allows the corresponding valve body 1224 to be inserted therein. The provision of the limiting groove can further improve the reliability of fixing the valve body 1224 and prevent the valve body 1224 from slipping due to pressure changes.

[0088] Continue to see Figure 6 In one or more embodiments, four mounting blocks 1232 spaced apart from each other along its circumference are further provided on the pressing block body. Each mounting block 1232 is located between two adjacent pressing columns 1233. Each mounting block 1232 extends vertically outward from the circumferential edge of the pressing block body. Preferably, the mounting blocks 1232, the pressing columns 1233 and the pressing block body can be integrally formed by injection molding using a suitable resin material, such as PC, PP, etc. Figure 6 In the orientation shown, the mounting blocks 1232 extend vertically from the circumferential edge of the pressure block body toward the direction close to the grid plate 121. Each mounting block 1232 has a generally arcuate shape. In the assembled state, each mounting block 1232 extends through the corresponding circumferential through hole 1223 and forms a snap fit with the corresponding circumferential mounting hole 1214. In one or more embodiments, a snap-fit protrusion 1313 (not shown in the figure) is formed at the end of each mounting block 1232, so that a reliable snap fit is formed between the mounting block 1232 and the circumferential mounting hole 1214. Furthermore, in one or more embodiments, an inclined guide surface (not shown in the figure) is also provided on each snap-fit protrusion 1313, so that the mounting block 1232 can pass through the circumferential through hole 1223 and the circumferential mounting hole 1214 more smoothly.

[0089] like Figure 1-Figure 5 As shown, in one or more embodiments, the medicine liquid cup 11 includes a circumferential ring wall 111 and a mounting plate 112 connected to each other. The circumferential ring wall 111 is rotatably arranged on the mist storage tank 13. The mounting plate 112 is arranged inside the circumferential ring wall 111 and extends radially along the circumferential ring wall 111. When the medicine liquid cup 11 is in a fixed position, the mounting plate 112, the circumferential ring wall 111 and the air intake one-way valve 12 can together form a fixed cavity (not marked in the figure) for accommodating the atomizer unit 30, so that the atomizer unit 30 is stably and reliably fixed between the mounting plate 112 and the air intake one-way valve 12.

[0090] Continue to see Figure 3 In one or more embodiments, a main air inlet hole 1111 is provided on the side of the circumferential ring wall 111 that is located away from the air inlet check valve 12 and is located on the mounting plate 112. Figure 3 In the illustrated orientation, primary air inlet 1111 is located on the rear side of mounting plate 112 within circumferential wall 111. Main air inlet 1111 has a generally circular shape or other suitable shape. The number and arrangement of primary air inlets can be adjusted based on actual needs. Furthermore, air guide holes 1122 are also provided on mounting plate 112, allowing external air to enter spacer 13 through primary air inlet 1111, air guide holes 1122, and air inlet check valve 12, sequentially. This airflow then entrains tiny drug particles to form an aerosol.

[0091] Continue to see Figure 3 In one or more embodiments, an auxiliary air intake hole 1112 is provided on the side of the circumferential ring wall 111 located near the air intake check valve 12 . Figure 3 In the illustrated orientation, auxiliary air inlet holes 1112 are provided on the circumferential wall 111, located in front of the mounting plate 112. Auxiliary air inlet holes 1112 are generally rectangular with rounded corners. The number and arrangement of auxiliary air inlet holes 1112 can be adjusted based on actual needs. The provision of auxiliary air inlet holes 1112 can increase the amount of air entering the spacer 13, thereby improving drug delivery efficiency.

[0092] Continue to see Figure 3 In one or more embodiments, a first bearing 1113 rotatably arranged on the connecting shaft 1312 is further provided on the circumferential ring wall 111, so that the entire medicine liquid cup 11 can be easily rotated relative to the spacer 13. Figure 3 In the orientation shown, the first bearing 1113 is arranged at the lower portion of the circumferential ring wall 111. Figure 5 In the assembled state, the first bearing 1113 on the circumferential ring wall 111 and the second bearing 1218 on the grid plate 121 are arranged on the connecting shaft 1312 at intervals from each other.

[0093] Continue to see Figure 3In one or more embodiments, a liquid outlet 1121 is further provided on the mounting plate 112. The liquid outlet 1121 is arranged roughly in the middle of the mounting plate 112. The liquid outlet 1121 has a roughly circular shape. In the assembled state, the liquid outlet 1121 is fluidically connected with the mist inlet 1311 on the mist storage tank 13 through the central through hole (including the first central through hole 1211, the second central through hole 1222 and the third central through hole 1231) on the air inlet one-way valve 12. Furthermore, when the medicine liquid cup 11 is in a fixed position, the liquid outlet 1121 has the same center line as the first central through hole 1211, the second central through hole 1222, the third central through hole 1231 and the mist inlet 1311, so that the medicine liquid has a straight flow path. Alternatively, the liquid outlet 1121 and the center lines of the first central through hole 1211 , the second central through hole 1222 , the third central through hole 1231 and the mist inlet 1311 may also be parallel to each other, as long as the flow path can be ensured to be unobstructed.

[0094] Continue to see Figure 3 and Figure 5 In one or more embodiments, the mounting plate 112 is provided with four air guide holes 1122 spaced apart from one another along the circumference of the liquid outlet 1121. Each air guide hole 1122 has a generally rectangular shape with rounded corners. The air guide holes 1122 can connect the main air inlet hole 1111 in the circumferential ring wall 111 with the air inlet check valve 12. It should be noted that the number, shape, and arrangement of the air guide holes 1122 can be adjusted according to actual needs.

[0095] Figure 7 Schematic diagram of the assembly structure of the embodiment of the integrated atomizer assembly and atomizer unit of the present invention. Figure 3 、 Figure 5 and Figure 7 As shown, in one or more embodiments, a plurality of clamping ribs spaced apart from each other are provided on one side of the mounting plate 112 close to the intake check valve 12. Figure 3 In the illustrated orientation, each clamping rib extends vertically forward from the front surface of the mounting plate 112. In the assembled state, the atomizer unit 30 of the nebulizer 1 can be constrained between the plurality of clamping ribs 1123, so that the atomizer unit and the liquid medicine cup 11 form a detachable connection.

[0096] Continue to see Figure 2-Figure 5 In one or more embodiments, the liquid medicine cup 11 further includes a portion disposed on a side of the mounting plate 112 away from the air inlet check valve 12 (based on Figure 3 The liquid storage cup 113 is located at the rear side of the mounting plate 112 to accommodate liquid medicine. The liquid storage cup 113 has a liquid inlet 1133 connected to the liquid outlet 1121. Figure 3In the orientation shown, the liquid inlet 1133 is located on the upper side of the circumferential ring wall 111. In one or more embodiments, the medicine liquid cup 11 further includes a cup lid 115 that can open and close the liquid inlet 1133. Furthermore, the liquid inlet 1133 is provided with a plurality of stopper protrusions 1134 spaced apart from each other along its circumference, so that the cup lid 115 can be securely locked to the liquid inlet 1133. Furthermore, an annular seal 114 is provided between the cup lid 115 and the liquid inlet 1133 to improve the sealing between the two. In one or more embodiments, the liquid storage cup 113 includes a curved plate 1131 connected to the mounting plate 112, and the curved plate 1131 and the mounting plate 112 together enclose a hollow liquid storage chamber 1132. The cross-section of the liquid storage chamber 1132 (i.e., the cross-section taken along a direction perpendicular to the mounting plate 112) gradually decreases in the vertical downward direction. In this way, the liquid medicine in the liquid storage chamber 1132 can flow smoothly under its own gravity, thereby reducing drug residue. Furthermore, the bottom of the liquid storage chamber 1132 is flush with the bottom of the liquid outlet 1121 on the mounting plate 112, preventing drug residue from remaining at the bottom of the liquid storage chamber 1132, thereby further reducing drug residue.

[0097] Continue to see Figure 1-Figure 4 In one or more embodiments, the curved plate 1131 of the liquid medicine cup 11 is further provided with a substantially vertical direction away from the mounting plate 112 (based on Figure 3 The connecting rib 1124 extends in the direction shown, i.e., rearward. The provision of the connecting rib 1124 facilitates a fixed connection with the main unit 20 of the nebulizer 1. Specifically, a locking hole (not shown) is provided on the connecting rib 1124, and a connecting groove (not shown) for receiving the connecting rib 1124 is provided on the main unit 20. The liquid medicine cup 11 is provided with a locking tongue (not shown) in the connecting groove that can be selectively inserted into the locking hole.

[0098] Continue to see Figure 1-Figure 5 In one or more embodiments, the medicine liquid cup 11 further includes a connecting tongue 116 connected to the circumferential ring wall 111. A snap-fitting hole 1161 is provided on the connecting tongue 116, which can form a snap-fitting fit with the snap-fitting protrusion 1313 on the spacer 13. The arrangement of the snap-fitting hole 1161 and the snap-fitting protrusion 1313 enables the medicine liquid cup 11 to conveniently form a detachable connection with the spacer 13, thereby realizing the conversion of the medicine liquid cup 11 between a fixed position and a movable position. In one or more embodiments, the connecting tongue 116 is configured to extend obliquely from the circumferential ring wall 111 to the spacer 13 toward the spacer 13. Based on Figure 3 In the orientation shown, the connecting tongue 116 extends obliquely upward from the back to the front.
