Description

Technical Field

[0001] The utility model relates to the technical field of atomization, and particularly relates to an atomization module and a drug delivery device comprising the same. Background Art

[0002] Atomization drug delivery is to atomize the liquid medicine so that the user can inhale the atomized liquid medicine into the lungs to achieve a direct and rapid therapeutic effect. The existing vibration atomization device converts the liquid medicine into tiny aerosol molecules through the high-frequency vibration of a piezoelectric sheet, so as to provide inhaled drug delivery treatment.

[0003] In order to make it convenient for the user to carry around, it is necessary to further reduce the volume of the atomization device. Therefore, miniaturizing the atomization module in the atomization device has become an important issue.

[0004] When attempting to conduct the piezoelectric sheet in the atomization module in a limited space, one solution is to extend and guide one of the positive and negative electrodes of the piezoelectric sheet so that it is arranged on the same side and conductively connected to the driving module respectively. Therefore, the electrode to be extended to the other side is completed by coating silver paste on the piezoelectric sheet and bending the silver paste along the surface of the piezoelectric sheet from one side to the other side. However, the above method may cause disconnection during the extension and bending process due to uneven coating of the silver paste, resulting in the defect of inability to conduct.

[0005] Therefore, how to simplify the conduction steps of the piezoelectric sheet through the improvement of the structural design to overcome the above defects has become one of the important issues to be solved in this field. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide an atomization module and a drug delivery device comprising the same in view of the deficiencies of the prior art.

[0007] To solve the above technical problem, one of the technical solutions adopted by the utility model is to provide an atomization module, which includes: an annular component, a piezoelectric sheet and a porous component. The annular component has a central region and an outer edge region surrounding the central region. The piezoelectric sheet is arranged in the outer edge region of the annular component. The piezoelectric sheet has a first electrode and a second electrode, and the first electrode and the second electrode are respectively arranged on different sides of the piezoelectric sheet. The porous component is arranged in the central region of the annular component. Wherein, the first electrode of the piezoelectric sheet faces the annular component, the annular component has an integrally formed first pin, and the second electrode of the piezoelectric sheet is electrically connected to a second pin through a bonding component.

[0008] Furthermore, the first pin extends away from the annular component from the outer edge region of the annular component.

[0010] Furthermore, the first electrode is the positive electrode, the second electrode is the negative electrode, the first pin is the positive pin, and the second pin is the negative pin.

[0011] Furthermore, the ring-shaped component and the piezoelectric sheet are bonded together with an adhesive layer.

[0012] Furthermore, the first electrode of the piezoelectric sheet is electrically connected to the ring-shaped component through a conductive adhesive.

[0013] Furthermore, the adhesive layer is a conductive adhesive.

[0014] Furthermore, the bonding component is solder.

[0015] To solve the above technical problems, another technical solution adopted by the present utility model is to provide a drug delivery device, which includes: a main body; a medicine cup connected to the main body and including a nozzle; and the atomization module as described above, and the atomization module is disposed in the medicine cup.

[0016] Furthermore, the nozzle includes a first electrode post and a second electrode post. One end of the first pin has a first ring sleeved on the first electrode post, and one end of the second pin has a second ring sleeved on the second electrode post.

[0017] Furthermore, the atomization module is disposed perpendicular to the outlet direction of the nozzle.

[0018] Furthermore, a spray port of the atomization module is perpendicular to the outlet direction of the nozzle.

[0019] Furthermore, the drug delivery device further includes a detection module disposed in the main body and used to cooperate with the ring-shaped component to detect the remaining amount of liquid medicine in the medicine cup.

[0020] One of the beneficial effects of the present utility model is that the atomization module provided by the present utility model and the drug delivery device including the same can simplify the manufacturing process steps of the atomization module and avoid the risk that the piezoelectric sheet cannot be driven due to silver glue disconnection in the prior art through the technical solutions of "the ring-shaped component has an integrally formed first pin" and "the piezoelectric sheet is disposed on the ring-shaped component and connected to a second pin through a bonding component".

Detailed implementation manners

[0030] The following are specific embodiments to illustrate the implementation manners of the present utility model regarding "atomization module and drug delivery device including the same". Those skilled in the art can understand the advantages and effects of the present utility model from the content disclosed in this specification. The present 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 the present utility model. Additionally, the drawings of the present utility model are only for simple schematic illustration and are not drawn according to actual dimensions, hereby stated in advance. The following implementation manners will further elaborate on the relevant technical content of the present utility model, but the disclosed content is not intended to limit the protection scope of the present utility model.

[0031] It should be understood that although terms such as "first", "second", "third", etc. may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another, or one signal from another. Additionally, the term "or" used herein should, depending on the actual situation, possibly include any combination of one or more of the associated listed items.

[0032] Referring to Figures 1 to 4 as shown, Figure 1 is a front view schematic diagram of the atomization module of the present utility model, Figure 2 is a three-dimensional schematic diagram of the atomization module of the present utility model, Figure 3 is Figure 2 a plan view schematic diagram in the III-III direction of Figure 4 is a rear view schematic diagram of the atomization module of the present utility model. An embodiment of the present utility model provides an atomization module M, which includes: an annular component 1, a piezoelectric sheet 2, and a porous component 3. The annular component 1 is generally circular, having a central region 1a and an outer edge region 1b surrounding the central region 1a, and can be used to carry the piezoelectric sheet 2. In other words, the piezoelectric sheet 2 is disposed on the outer edge region 1b of the annular component 1, and the piezoelectric sheet 2 can be fixed to the annular component 1 through an adhesive layer 4. The piezoelectric sheet 2 has a first electrode 2a and a second electrode 2b, and the first electrode 2a and the second electrode 2b are respectively disposed on different sides of the piezoelectric sheet 2. The porous component 3 is disposed in the central region 1a of the annular component 1. Among them, the first electrode 2a of the piezoelectric sheet 2 faces the annular component 1; the annular component 1 has an integrally formed first lead 11, and the second electrode 2b of the piezoelectric sheet 2 is electrically connected to a second lead 21 through a bonding component 22.

[0033] Since the annular component 1 has an integrally formed first lead 11, the first lead 11 does not need to be combined with the annular component 1 by welding as in the prior art, thereby achieving the purpose of streamlining the manufacturing process. In addition, the first lead 11 can extend away from the annular component 1 from the outer edge region 1b of the annular component 1, or the first lead 11 can extend outward along at least two directions from the outer edge region 1b of the annular component 1.

[0034] For example, in one aspect, the first lead 11 integrally formed with the annular component 1 can extend from the side of the first electrode 2a of the piezoelectric sheet 2 away from the annular component 1 to the side of the second electrode 2b of the piezoelectric sheet 2.

[0035] Or, in another aspect, as Figure 2 and Figure 3As shown, the first pin 11 can first extend horizontally away from the annular component 1 along the outer edge region 1b of the annular component 1; then, the first pin 11 is bent at a first angle A1 in the vertical direction and continues to extend; finally, after the first pin 11 is bent at a second angle A2 in the horizontal direction, it continues to extend away from the annular component 1.

[0036] Therefore, the above two extension methods of the first pin 11 can both achieve the purpose of extending the first pin 11 to the same side as the second pin 21, thereby omitting the step of bending the silver paste in the prior art and avoiding the risk of wire breakage during the process of bending the silver paste.

[0037] In addition, during the process of electrically connecting the piezoelectric sheet 2 to the second pin 21 through the bonding component 22, the bonding component 22 is preferably solder, but is not limited thereto. In addition, the position where the bonding component 22 is disposed on the piezoelectric sheet 2 is the second electrode 2b of the piezoelectric sheet 2.

[0038] Specifically, the annular component 1 and the piezoelectric sheet 2 may have an annular hollow shape to place the porous component 3 at the hollow position. In one embodiment, the porous component 3 can be fixed at the center of the annular component 1 through an annular fixing member 5. For example, the porous component 3 can be a sieve, and the fixing member 5, the porous component 3 and the piezoelectric sheet 2 are disposed on the same side of the annular component 1. However, the present invention is not limited to the above examples.

[0039] When the liquid medicine is supplied to the atomization module M, and the driving voltage is supplied to the atomization module M through the first pin 11 and the second pin 21, the piezoelectric sheet 2 will generate high-frequency oscillations, and then actuate the porous component 3, so that the porous component 3 can atomize the liquid medicine to generate aerosol molecules. In other words, the liquid medicine can become an aerosol form through the multiple through holes of the porous component 3 to achieve the purpose of atomized drug delivery. Specifically, the porous component 3 can be made of palladium-nickel alloy or ceramic. However, the present invention is not limited to the above examples.

[0040] In one embodiment of the present invention, the first electrode 2a is the positive electrode, the second electrode 2b is the negative electrode, the first pin 11 can be the positive electrode pin, and the second pin 21 can be the negative electrode pin. However, the above examples are only one feasible embodiment and are not used to limit the present invention. In another embodiment of the present invention, the first electrode 2a can be the negative electrode, the second electrode 2b can be the positive electrode, the first pin 11 is the negative electrode pin, and the second pin 21 is the positive electrode pin.

[0041] In an embodiment of the present utility model, when the piezoelectric sheet 2 is fixed to the annular component 1 through the adhesive layer 4 and the adhesive layer 4 is a non-conductive adhesive, the first electrode 2a of the piezoelectric sheet 2 is electrically connected to the annular component 1 through a conductive adhesive 4a. Among them, the aforementioned conductive adhesive 4a can also be silver paste or other forms. In addition, the conductive adhesive 4a can further extend along the surface of the first pin 11 in a direction away from the annular component 1 and be electrically connected to the following electrode post.

[0042] In another embodiment of the present utility model, the adhesive layer 4 can directly be in the form of a conductive adhesive, so that the first electrode 2a of the piezoelectric sheet 2 directly contacts the conductive adhesive layer 4 and thus conducts with the entire annular component 1. In other words, when the first electrode 2a of the piezoelectric sheet 2 is the positive electrode, through the conduction of the conductive adhesive layer 4, the entire annular component 1 will be the positive electrode, and the first pin 11 will be the positive electrode pin.

[0043] Refer to Figure 5 and 6 as shown, Figure 5 is a three-dimensional schematic diagram of the drug delivery device of the present utility model, Figure 6 is an exploded schematic diagram of the atomization module of the present utility model installed in the drug delivery device. The present utility model also provides a drug delivery device D, which includes: a main body 10 and a medicine cup 20. The medicine cup 20 is connected to the main body 10. For example, the medicine cup 20 is connected above the main body 10. The main body 10 can be used to provide power to the medicine cup 20. The medicine cup 20 can have a nozzle 20a, and a first electrode post 201 and a second electrode post 202 are provided at a position of the nozzle 20a corresponding to the atomization module M.

[0044] In addition, the atomization module M provided by the present utility model can be arranged in the medicine cup 20. Further, the first pin 11 of the atomization module M can have a first ring 111, and the second pin 21 of the atomization module M can have a second ring 211. Specifically, the first ring 111 can be arranged at one end of the first pin 11 away from the annular component 1, and the second ring 211 can be arranged at one end of the second pin 21 away from the piezoelectric sheet 2.

[0045] Accordingly, when the atomization module M is arranged in the medicine cup 20, the first ring 111 of the first pin 11 can be sleeved on the first electrode post 201, and the second ring 211 of the second pin 21 can be sleeved on the second electrode post 202, thereby achieving the purpose of electrical connection.

[0046] Please refer to Figure 5, in an embodiment of the present utility model, taking direction d1 as the direction parallel to the horizontal plane and direction d2 as the direction perpendicular to the horizontal plane as an example, the atomization module M can be installed vertically in the medicine cup 20 with respect to direction d1. Specifically, the atomization module M can be arranged perpendicular to the outlet direction of the nozzle. Alternatively, one spray port of the atomization module M can be perpendicular to the outlet direction of the nozzle 20a (i.e., the atomization module M is arranged perpendicular to direction d2). However, the above description is only an example and is not intended to limit the present utility model.

[0047] As Figure 5 and Figure 6 shown, the drug delivery device D of the present utility model may further include a detection module 6, and the detection module 6 is preferably arranged in the main body 10. The detection module 6 can cooperate with the ring-shaped component 1 to detect the residual amount of the liquid medicine in the medicine cup 20. Specifically, in an embodiment, since the atomization module M provided by the present utility model can use the entire ring-shaped component 1 as the positive electrode, the electrical signal from the positive electrode column (i.e., the first electrode column 201) can be conducted to the liquid medicine in the medicine cup 20 through the ring-shaped component 1, and the detection module 6 can receive the voltage change from the liquid medicine in a non-contact manner to judge the residual amount of the liquid medicine in the medicine cup 20.

[0048] [Advantages of the embodiment]:

[0049] One of the advantages of the present utility model is that the atomization module provided by the present utility model and the drug delivery device including the same can simplify the manufacturing process steps of the atomization module and avoid the risk that the piezoelectric sheet cannot be driven due to silver glue wire breakage in the prior art through the technical solutions of "the ring-shaped component has an integrally formed first pin" and "the piezoelectric sheet is arranged on the ring-shaped component and connected to the second pin through a bonding component".

[0050] Furthermore, since the atomization module provided by the present utility model can use the entire ring-shaped component as the positive electrode, the electrical signal from the positive electrode column can be conducted to the liquid medicine in the medicine cup through the ring-shaped component, and the detection module can receive the voltage change from the liquid medicine in a non-contact manner to judge the residual amount of the liquid medicine in the medicine cup, so that the atomization module of this case further has the effect of detecting without water.

[0051] The content disclosed above is only the preferred feasible embodiment of the present utility model, and does not limit the protection scope of the claims of the present utility model.
