Description

Technical Field

[0001] This utility model relates to an atomizer and its housing assembly, and more particularly to an atomizer and its housing assembly that improves the user's breathing pattern. Background Technology

[0002] Generally speaking, when operating a nebulizer, if users wish to increase the amount of drug aerosol particles deposited in the lungs to enhance the therapeutic effect, in addition to controlling the deposition of the nebulized drug aerosol particle size (MMAD) in specific areas of the lungs, they can also further increase the deposition ratio of aerosol particles in the lungs by using a deep and slow breathing rhythm.

[0003] To guide users to use nebulizers with a steady and slow breathing rhythm, a common method is to narrow the air inlet of the nebulizer to increase airflow resistance during inhalation. However, while this design encourages users to slow their inhalation, it also increases airflow resistance during exhalation, which may cause discomfort when using the nebulizer and even affect the tolerance to long-term treatment.

[0004] Therefore, how to overcome the above-mentioned defects by improving the structural design of the internal airflow channel of the atomizer has become one of the important issues to be solved in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a nebulizer and its housing assembly to address the shortcomings of the prior art, so as to solve the technical problem that the existing nebulizers cannot reduce the impact on the user's breathing comfort while improving the treatment effect.

[0006] To solve the aforementioned technical problems, one technical solution adopted by this utility model is to provide an atomizer, which includes a main unit, a housing assembly, a cup body, and an atomizing module. The housing assembly includes a housing and an elastic shielding member. The housing is joined to the main unit, and has an air chamber inside. The housing includes a nozzle orifice, and its sidewall has multiple openings, which communicate with the nozzle orifice through the air chamber. The elastic shielding member is disposed on the sidewall of the housing. The elastic shielding member shields at least one of the multiple openings, and is used to dynamically adjust the flow rate of the airflow through the multiple openings based on the direction of the airflow entering and exiting the nozzle orifice. The cup body is joined to the housing. The cup body has a liquid storage chamber inside. The bottom of the cup body has a through hole communicating with the liquid storage chamber, which in turn communicates with the air chamber. The atomizing module is disposed inside the cup body and located directly above the through hole.

[0007] Optionally, the plurality of openings are further divided into two first openings and at least one second opening, the two first openings and the nozzle orifice being located on opposite sides of the housing, and the elastic shielding member shielding the at least one second opening.

[0008] Optionally, the elastic shielding member shields the outside of the at least one second opening.

[0009] Optionally, when a user inhales into the nozzle, the airflow in the air chamber flows toward the nozzle, and the elastic shield is pulled by the airflow to press against the at least one second opening.

[0010] Optionally, when a user exhales into the nozzle, the airflow in the air chamber flows toward the plurality of openings, and the elastic shield is pushed open by the airflow, exposing at least one second opening.

[0011] Optionally, the at least one second opening is completely covered by the projected area of ​​the elastic shielding member projected onto the side wall of the housing.

[0012] Optionally, the number of second openings is one, located between the two first openings.

[0013] Optionally, the elastic shielding member has an air hole, and the second opening communicates with the air hole.

[0014] Optionally, there are two second openings, and the positions of the two second openings are located below the nozzle orifice, and the positions of the two second openings are closer to the nozzle orifice than the positions of the first openings.

[0015] Optionally, the housing has a partition wall disposed inside the nozzle orifice. The hollow space above the partition wall forms an air chamber, and the hollow space below the partition wall forms a sensing chamber. The air chamber and the sensing chamber are independent and non-communicating spaces, and two second openings are connected to the sensing chamber.

[0016] Optionally, the elastic shielding member has at least one fastener, and the side wall of the housing has at least one fastening groove corresponding to the at least one fastener. The elastic shielding member is fixed to the side wall by being engaged with the at least one fastener in the at least one fastening groove.

[0017] To address the aforementioned technical problems, another technical solution adopted by this utility model is to provide a housing assembly, which includes a housing and an elastic shielding member. The housing has an internal air chamber, a nozzle orifice, and a plurality of openings on its sidewalls, the openings communicating with each other through the air chamber. The elastic shielding member is disposed on the sidewalls of the housing, shielding the outside of at least one of the plurality of openings. The elastic shielding member is used to dynamically adjust the flow rate of the airflow through the plurality of openings in response to the direction of the airflow entering and exiting the nozzle orifice.

[0018] Optionally, the plurality of openings are further divided into two first openings and at least one second opening, the two first openings and the nozzle orifice being located on opposite sides of the housing, and the elastic shielding member shielding the at least one second opening.

[0019] Optionally, when a user inhales into the nozzle, the airflow in the air chamber flows toward the nozzle, and the elastic shield is pulled by the airflow to press against the at least one second opening.

[0020] Optionally, when a user exhales into the nozzle, the airflow in the air chamber flows toward the plurality of openings, and the elastic shield is pushed open by the airflow, exposing at least one second opening.

[0021] Optionally, the projected area of ​​the elastic shielding member onto the sidewall of the housing completely overlaps with the at least one second opening.

[0022] Optionally, the number of second openings is one, located between the two first openings.

[0023] Optionally, the elastic shielding member has an air hole, and the second opening communicates with the air hole.

[0024] Optionally, there are two second openings, and the positions of the two second openings are located below the nozzle orifice, and the positions of the two second openings are closer to the nozzle orifice than the positions of the first openings.

[0025] Optionally, the housing has a partition wall disposed inside the nozzle orifice. The hollow space above the partition wall forms an air chamber, and the hollow space below the partition wall forms a sensing chamber. The air chamber and the sensing chamber are independent and non-communicating spaces, and two second openings are connected to the sensing chamber.

[0026] One of the beneficial effects of this invention is that the nebulizer and its housing assembly provided by this invention can utilize an elastic shielding member to cover the outside of at least one of the plurality of openings. This allows the elastic shielding member to cover or open at least one of the plurality of openings depending on the direction of airflow into and out of the nozzle, thereby dynamically adjusting the flow rate of airflow through the plurality of openings. Therefore, when a user inhales through the nebulizer, the airflow direction causes the elastic shielding member to partially cover the opening, thereby increasing inhalation resistance and guiding the user to inhale the nebulized medication at a slower and more stable pace. Conversely, when the user exhales, the airflow direction keeps the elastic shielding member open, preventing the opening from being covered, thus avoiding increased exhalation resistance and ensuring the user's breathing comfort. This design improves the therapeutic effect while reducing discomfort during inhalation and exhalation, enhancing the user's treatment experience.

[0048] The following specific embodiments illustrate the implementation of the "atomizer and its housing assembly" disclosed in this utility model. Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of this utility model. Furthermore, the accompanying drawings of this utility model are for simple illustrative purposes only and are not depictions of actual dimensions, as stated in advance. The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the scope of protection of this utility model.

[0049] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components, these components should not be limited by these terms. These terms are primarily used to distinguish one component from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more related listed items.

[0050] First Embodiment

[0051] See Figures 1 to 3 As shown, the first embodiment of this utility model provides an atomizer D, which mainly includes a housing assembly M1, a main unit 3 and a cup body 4, and the housing assembly M1 includes a housing 1 and an elastic shielding member 2.

[0052] See Figure 4 and Figure 5As shown, the housing 1 includes a nozzle 13, a top interface 15, and a bottom interface 16. The cup body 4 is connected to the housing 1 via the top interface 15, and the main unit 3 is connected to the housing 1 via the bottom interface 16. The interior of the housing 1 is hollow and has an air chamber C1. The side wall 1S of the housing 1 has multiple openings, which communicate with the nozzle 13 through the air chamber C1.

[0053] See Figures 3 to 5 As shown, specifically, the plurality of openings can be further divided into first openings 11 and second openings 12. This invention is not limited by the number of first openings 11 and second openings 12. In the first embodiment, there are two first openings 11 and one second opening 12, with the second opening 12 located between the two first openings 11. Furthermore, the plurality of openings (two first openings 11 and one second opening 12) and the nozzle opening 13 are located on opposite sides of the housing 1. The first openings 11 and second openings 12 mainly serve as inlet / outlet air ports to ensure airflow within the air chamber C1.

[0054] The cup body 4 has a liquid storage chamber C2 inside for storing liquid medicine (not shown in the figure). The bottom of the cup body 4 has a through hole 40 communicating with the liquid storage chamber C2. The liquid storage chamber C2 is connected to the air chamber C1 through the through hole 40. The nebulizer D also includes an atomizing module 5. The atomizing module 5 is located inside the cup body 4, directly above the through hole 40. For example, the atomizing module 5 can be made of piezoelectric ceramic material, which can generate high-frequency vibration under appropriate voltage driving, thus atomizing the liquid medicine into an aerosol (not shown in the figure). After the liquid medicine is atomized into an aerosol by the atomizing module 5 through the through hole 40, it is stored in the air chamber C1 and then inhaled into the upper respiratory tract and lungs by the user (not shown in the figure) through the nozzle 13.

[0055] See Figures 5 to 7 As shown, the elastic shielding member 2 is disposed on the side wall 1S of the housing 1 and shields the second opening 12. More specifically, the side wall 1S of the housing 1 also has a locking hole 14, and the elastic shielding member 2 has a locking member 21, the shape and position of which correspond to the shape and position of the locking hole 14. The elastic shielding member 2 is fixed to the side wall 1S by the locking member 21 engaging with the locking hole 14. It should be noted that the number of locking members 21 and locking holes 14 is not limited in this invention. For example, the material of the elastic shielding member 2 can be silicone, thermoplastic elastomer (TPE), or polyurethane (PU), etc., and this invention is not limited thereto.

[0056] In the first embodiment, the elastic shielding member 2 is a single sheet. Further, as... Figure 5 and Figure 6 As shown, the projected area of ​​the elastic shielding member 2 onto the side wall 1S of the housing 1 completely overlaps with the second opening 12, and the elastic shielding member 2 shields the outside of the second opening 12. That is, the second opening 12 is completely covered by the projected area of ​​the elastic shielding member 2 onto the side wall 1S of the housing 1 (i.e., the projected area of ​​the elastic shielding member 2 is greater than or equal to the aperture size of the second opening 12). Therefore, see... Figure 8 As shown (can be viewed together) Figure 4 When the user inhales through nozzle 13 and inhales the aerosol in air chamber C1 into their body, the airflow in air chamber C1 flows toward nozzle 13 (see...). Figure 8 The airflow direction N1 causes the elastic shielding member 2 to be pulled tightly against the second opening 12 by the airflow.

[0057] Because the second opening 12 is completely covered by the elastic shielding member 2, and the elastic shielding member 2 fits tightly against the second opening 12, external air cannot enter the air chamber C1 inside the housing 1 through the second opening 12, which increases the resistance when the user inhales. In this situation, in order to smoothly inhale the aerosol (nebulized drug solution), the user will naturally adjust their breathing rhythm and adopt a slower and deeper inhalation. This inhalation mode not only helps the aerosol enter the respiratory tract smoothly, but also promotes the aerosol to penetrate deep into the lungs, allowing the drug particles to be deposited more effectively in the lung tissue, thus improving the efficacy of the drug. In addition, appropriate inhalation resistance can also help the user maintain a stable inhalation rate, avoiding premature deposition of aerosol particles in the mouth or throat due to excessively rapid inhalation, thereby improving the delivery efficiency of the drug.

[0058] On the other hand, see Figure 9 As shown (can be viewed together) Figure 4 When the user exhales from the nozzle 13, the airflow will flow toward the first opening 11 and the second opening 12 on the housing 1 (see...). Figure 9 The airflow direction is N2. Because the elastic shield 2 is elastic and sheet-like, it opens when pushed by airflow, exposing the second opening 12 and allowing exhaled airflow to escape smoothly. In other words, when the user exhales, the elastic shield 2 does not cover the second opening 12, thus effectively reducing exhalation resistance, ensuring smooth breathing, and improving overall user comfort. In addition, this design prevents pressure buildup inside the housing 1 of the nebulizer D due to exhalation, avoiding affecting the nebulization effect during the next inhalation, thereby improving the stability and efficiency of the nebulizer D. In other words, the elastic shield 2 dynamically adjusts the flow rate of airflow through the multiple openings based on the direction of airflow entering and exiting the nozzle 13, and the function of the elastic shield 2 is equivalent to a one-way valve (allowing airflow to pass in only one direction).

[0059] Second Embodiment

[0060] See Figures 10 to 13 The second embodiment of this utility model provides a housing assembly M2. The structure of the housing assembly M2 in the second embodiment is similar to that of the housing assembly M1 in the first embodiment, and the similarities will not be repeated. The main difference lies in the structural shape of the elastic shielding member 2 in the second embodiment, which differs from that in the first embodiment. Therefore, the housing assembly M2 of the second embodiment is also applicable to the first embodiment (see...). Figures 1 to 4 The atomizer D described in the second embodiment, namely the housing assembly M2, can replace the housing assembly M1 in the first embodiment.

[0061] Mainly, the housing assembly M2 includes a housing 1 and an elastic shielding member 2. The side wall 1S of the housing 1 has two first openings 11 and one second opening 12, with the second opening 12 located between the two first openings 11, and the elastic shielding member 2 shielding the second opening 12. Further, in the second embodiment, the side wall 1S of the housing 1 also has two locking holes 14, with the second opening 12 located between the two locking holes 14. The elastic shielding member 2 also has two fasteners 21 corresponding to the two locking holes 14. The elastic shielding member 2 is fixed to the housing 1 by being respectively engaged in the two locking holes 14 by the two fasteners 21. In addition to the two fasteners 21, the elastic shielding member 2 also includes a hollow frame 22 and a shielding sheet 23, the shielding sheet 23 being elastic and sheet-like. Two fasteners 21 are set on the hollow frame 22, the first end 231 on the upper side of the shielding plate 23 is connected to the hollow frame 22, and the second end 232 on the lower side of the shielding plate 23 is a free end.

[0062] See Figures 13 to 15 As shown, when a user inhales through nozzle 13 and draws the aerosol from air chamber C1 into their body, the airflow within air chamber C1 flows toward nozzle 13 (see...). Figure 14 The airflow direction N1 causes the shielding plate 23 of the elastic shielding member 2 to be pulled tightly against the second opening 12 by the airflow. External air cannot enter the air chamber C1 inside the housing 1 through the second opening 12, resulting in increased flow resistance. This guides the user to adjust their breathing rhythm and adopt a slower and deeper inhalation method. On the other hand, when the user exhales from the nozzle 13, the airflow will flow towards the first opening 11 and the second opening 12 (see...). Figure 15 In the direction of airflow N2), the shielding piece 23 of the elastic shielding member 2 is pushed open by the airflow, exposing the second opening 12, thereby allowing the exhaled airflow to be discharged smoothly, effectively reducing the resistance to exhalation, and ensuring smooth breathing.

[0063] In addition, see Figure 16As shown, to further promote airflow inside and outside the housing 1, the elastic shielding member 2 is also provided with air holes 20 on its shielding plate 23, and the second opening 12 is connected to the air holes 20, so that when the user inhales, a guiding airflow can still be generated in the center of the air chamber C1 through the air holes 20, thereby increasing the guiding effect of the aerosol in the air chamber C1. It should be noted that the aperture size of the air holes 20 is much smaller than that of the first opening 11 and the second opening 12, so that the elastic shielding member 2 can maintain its effect of shielding the second opening 12 to increase the suction resistance.

[0064] Third Embodiment

[0065] See Figure 17 and Figure 18 As shown, the third embodiment of this utility model provides a housing assembly M3 suitable for an atomizer D. The structure of the housing assembly M3 in the third embodiment (including a housing 1 and an elastic shielding member 2) is similar to that of the housing assembly M1 in the first embodiment, and the similarities will not be repeated. The main difference is that the structural shape of the housing assembly M3 in the third embodiment is different from that in the first embodiment.

[0066] exist Figure 17 and Figure 18 In this housing 1, there are two first openings 11 and two second openings 12, and the opening directions of the first openings 11 and the second openings 12 are different. The two first openings 11 are located on the side wall 1S of the housing 1, and are situated on opposite sides of the housing 1, respectively, along with the nozzle opening 13. Please refer to [further details]. Figure 4 , Figure 19 The housing 1 further includes a partition wall P. The partition wall P is disposed within the nozzle orifice 13 and extends rearward to separate the top interface 15 and the bottom interface 16. A hollow space above the partition wall P forms an air chamber C1, and a hollow space below the partition wall P forms a sensing chamber R, which houses a sensing component (not shown). For example, the sensing component may be a pressure sensor. The air chamber C1 and the sensing chamber R are independent and non-communicating spaces, and two second openings 12 communicate with the sensing chamber R. The two second openings 12 are located below the nozzle orifice 13 of the housing 1; therefore, in the third embodiment, the second openings 12 communicate with the sensing chamber R below the partition wall P, and the positions of the two second openings 12 are closer to the nozzle orifice 13 than the position of the first opening 11. The elastic shielding member 2 has two shielding plates 23, which respectively shield the two second openings 12. In other words, the housing assembly M3 of the third embodiment has multiple check valves, while the housing assemblies M1 and M2 of the first and second embodiments have a single check valve.

[0067] See Figure 17 , Figure 19 and Figure 20As shown, when a user inhales through the nozzle 13 and draws the aerosol from the air chamber into their body, the airflow in both the air chamber C1 and the sensing chamber R flows toward the nozzle 13. At this time, the two shielding plates 23 located below the sensing chamber R are pulled by the airflow and press tightly against the second opening 12. External air cannot enter the sensing chamber R inside the housing 1 through the second opening 12, resulting in increased flow resistance. This guides the user to adjust their breathing rhythm and adopt a slower and deeper inhalation. On the other hand, when the user exhales from the nozzle 13, the airflow flows toward the first opening 11 on the side of the air chamber C1 and the second opening 12 on the side of the sensing chamber R. At this time, the two shielding plates 23 located below the sensing chamber R are pushed open by the airflow, exposing the second opening 12, thereby allowing the exhaled airflow to be discharged smoothly, effectively reducing exhalation resistance and ensuring smooth breathing.

[0068] Beneficial effects of the embodiments

[0069] Existing nebulizers often fail to simultaneously improve therapeutic efficacy and user comfort. While increasing inspiratory resistance can help increase drug deposition in the lungs, it also increases inspiratory and exhalation airflow resistance, affecting the patient's treatment experience. Therefore, the nebulizer and its housing assembly provided by this invention utilize an elastic shielding member to cover the outside of at least one of the plurality of openings. This allows the elastic shielding member to cover or open at least one of the plurality of openings depending on the different directions of airflow entering and exiting the nozzle, thereby dynamically adjusting the flow rate of airflow through the plurality of openings.

[0070] Furthermore, when a user inhales through the nozzle 13 and draws the aerosol from the air chamber into their body, the airflow within the air chamber flows towards the nozzle 13, causing the elastic shield 2 to be pulled tightly against the second opening 12 by this airflow. Because the second opening 12 is completely covered by the elastic shield 2, and the elastic shield 2 is tightly fitted to the second opening 12, external air cannot enter the air chamber within the housing 1 through the second opening 12, resulting in increased resistance during inhalation. In this situation, to smoothly inhale the aerosol (nebulized medication), the user will naturally adjust their breathing rhythm, adopting a slower and deeper inhalation. This inhalation mode not only helps the aerosol enter the respiratory tract smoothly but also promotes deeper penetration into the lungs, allowing the drug particles to be deposited more effectively in the lung tissue, thus enhancing the efficacy of the medication.

[0071] On the other hand, when the user exhales from the nozzle 13, the airflow flows towards the first opening 11 and the second opening 12 on the housing 1. Because the elastic shield 2 is elastic and sheet-like, it opens when pushed by the airflow, exposing the second opening 12 and allowing the exhaled airflow to escape smoothly. In other words, when the user exhales, the elastic shield 2 does not cover the multiple openings, thus effectively reducing exhalation resistance, ensuring smooth breathing, and improving overall user comfort. Furthermore, this design prevents pressure buildup inside the housing 1 of the atomizer D due to exhalation, avoiding affecting the atomization effect during the next inhalation, thereby improving the stability and performance of the atomizer D.
