Referring to FIG. 1 to FIG. 15, an embodiment of the present disclosure provides an aerosol generating device that can be applied to medical field, but the present disclosure is not limited thereto. As shown in FIG. 1 to FIG. 3, the aerosol generating device includes an aerosol generator 1000 and a plug 2000 detachably inserted into the aerosol generator 1000. The plug 2000 is electrically coupled to an external electricity source (not shown) to drive the aerosol generator 1000. It should be noted that, the aerosol generator 1000 in the present embodiment is cooperated with the plug 2000, but in other embodiments of the present disclosure, the aerosol generator 1000 can be independently applied or can be in cooperation with other components.

As shown in FIG. 4 and FIG. 5, the aerosol generator 1000 includes a container 200 and an atomizing module 100 assembled in the container 200. It should be noted that, the atomizing module 100 in the present embodiment is cooperated with the container 200, but in other embodiments of the present disclosure, the atomizing module 100 can be independently applied or can be in cooperation with other components.

Moreover, the container 200 has a liquid chamber 201, an aerosol chamber 202, a receiving chamber 203 arranged between the liquid chamber 201 and the aerosol chamber 202, and an insertion slot 204 that is in spatial communication with the receiving chamber 203. In other words, the container 200 of the present embodiment is formed by a cup 200a and a cover 200b assembled in (e.g., screwed into) the cup 200a, and the atomizing module 100 is sandwiched between the cup 200a and the cover 200b, but the present disclosure is not limited thereto. In the present embodiment, the cup 200a defines the liquid chamber 201 and the insertion slot 204, and the cup 200a and the cover 200b jointly define the aerosol chamber 202 and the receiving chamber 203.

The atomizing module 100 is disposed in the receiving chamber 203 of the container 200. That is to say, the liquid chamber 201 and the aerosol chamber 202 are respectively arranged at two opposite sides of the atomizing module 100 (e.g., the upper side and the lower side of the atomizing module 100 shown in FIG. 4), and are in spatial communication with each other through the atomizing module 100. The insertion slot 204 is configured to receive and hold the plug 2000, and the plug 2000 is electrically coupled to the atomizing module 100 so as to provide electricity to drive the atomizing module 100.

Specifically, the liquid chamber 201 is configured to receive medicinal liquid (not shown), and when the medicinal liquid flows from the liquid chamber 201 toward the aerosol chamber 202, the medicinal liquid is atomized to become atomized liquid by the atomizing module 100, so that a user can inhale the atomized liquid from the aerosol chamber 202. The atomized liquid in the present embodiment means that each particle of the atomized liquid has a diameter within a range of 3.5˜3.5 μm. The container 200 can be adjusted or changed according to design requirements.

In the present embodiment, a central axis C1 of the liquid chamber 201 overlaps a central axis C2 of the aerosol chamber 202. The liquid chamber 201 is tapered along a direction toward the aerosol chamber 202, and the liquid chamber 201 in the present embodiment is approximately in a warhead shape. Accordingly, the structure of the liquid chamber 201 can allow the medicinal liquid to flow smoothly, thereby effectively preventing bubbles from being generated in the medicinal liquid.

Moreover, the insertion slot 204 of the present embodiment defines an insertion direction S. In other words, the plug 2000 is inserted into the insertion slot 204 along the insertion direction S. The insertion direction S and the central axis C1 of the liquid chamber 201 have an acute angle therebetween. The insertion slot 204 has a thru-hole 2041 that is in spatial communication with the receiving chamber 203. The insertion slot 204 in the present embodiment is not integrally formed with any conductive terminal, or is not undetachably fixed with any conductive terminal. Accordingly, when the container 200 is discarded after being used, the discarded container 200 does not have any conductive terminal, thereby effectively avoiding waste of resources, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure, the insertion slot 204 can be undetachably fixed with at least one conductive terminal.

As shown in FIG. 6 to FIG. 8, the atomizing module 100 in the present embodiment includes an annular vibration plate 1, a microporous member 2 disposed on the vibration plate 1, a circuit board 3 electrically coupled to the vibration plate 1, two solders 4 electrically connected to the vibration plate 1 and the circuit board 3, a buffer 5 sandwiched between the vibration plate 1 and the circuit board 3, a sheet-like carrier 6 carrying the vibration plate 1, an electronic component 7 mounted on the circuit board 3, a bottom gasket 8 sandwiched between the carrier 6 and the container 200 (e.g., the cover 200b shown in FIG. 4), and an inner gasket 9 sandwiched between the vibration plate 1 and the container 200 (e.g., the cup 200a shown in FIG. 4).

It should be noted that, while the atomizing module 100 of the present embodiment includes the above components, the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure, the number, structure, or connection relationship of each component of the atomizing module 100 can be adjusted according to design requirements, and the atomizing module 100 can be cooperated with components other than the above components of the present embodiment.

As shown in FIG. 7 and FIG. 8, the vibration plate 1 in the present embodiment is a ring-shaped piezoelectric (PZT) plate, and has a circular first hole 11 defined by an inner edge thereof. The vibration plate 1 is sequentially defined along a direction away from the first hole 11 as an annular inner segment 12, an annular middle segment 13, and an annular outer segment 14. Specifically, a width ratio (i.e., W1: W2: W3) of the inner segment 12, the middle segment 13, and the outer segment 14 in a radius of the vibration plate 1 is 1:3:3, but the present disclosure is not limited thereto.

Moreover, the vibration plate 1 includes two electrical contacts 15a, 15b arranged on the same surface thereof (e.g., the top surface of the vibration plate 1 shown in FIG. 8) or located on a first plane. Since the two electrical contacts 15a, 15b cannot be vibrated, each of the two electrical contacts 15a, 15b is preferably arranged on at least one of the middle segment 13 and the outer segment 14 of the vibration plate 1 so as to avoid affecting the vibration performance of the vibration plate 1. The number of the electrical contacts 15a, 15b of the vibration plate 1 in the present embodiment is two, but in other embodiments of the present disclosure, the vibration plate 1 can include only one electrical contact.

In addition, the structure of each of the two electrical contacts 15a, 15b can be adjusted according to design requirements. In the present embodiment, as shown in FIG. 9, the vibration plate 1 includes a top electrode and a bottom electrode both respectively arranged on a top surface and a bottom surface of a periphery portion thereof, and the top electrode is defined as the electrical contact 15b. Moreover, the bottom electrode (e.g., a substantially rectangular portion of the vibration plate 1 represented by the dotted lines shown in FIG. 9) is further formed with a conductive layer that extends from the bottom electrode to the top surface of the periphery portion of the vibration plate 1 through a lateral side of the vibration plate 1, and a portion of the conductive layer arranged on the top surface of the vibration plate 1 is defined as the electrical contact 15a.

As shown in FIG. 8 and FIG. 10, the microporous member 2 in the present embodiment is a circular film made of a metallic material or a polymeric material, and the microporous member 2 has a plurality of atomizing holes 21 penetratingly formed in a substantially central portion thereof. The number and structure of the atomizing holes 21 can be adjusted according to design requirements (e.g., according to the diameter of particles of the atomized liquid).

Moreover, the microporous member 2 is disposed on the vibration plate 1 and covers the first hole 11, and the microporous member 2 in the present embodiment is sandwiched between the vibration plate 1 and the carrier 6, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure, one of the microporous member 2, the vibration plate 1, and the carrier 6 can be sandwiched between the other two of the microporous member 2, the vibration plate 1, and the carrier 6. Accordingly, the liquid chamber 201 and the aerosol chamber 202 of the container 200 are in spatial communication with each other through the microporous member 2.

Specifically, the carrier 6 in the present embodiment is in an annular shape and has a circular second hole 61 defined by an inner edge thereof, and a diameter of the second hole 61 is smaller than that of the first hole 11. The microporous member 2 covers the second hole 61 of the carrier 6 (i.e., the first hole 11 and the second hole 61 are separated from each other by the microporous member 2), so that the liquid chamber 201 and the aerosol chamber 202 are in spatial communication with each other through a portion of the microporous member 2 that covers the second hole 61. Moreover, the atomizing holes 21 of the microporous member 2 are preferably arranged in the portion of the microporous member 2 that covers the second hole 61.

As shown in FIG. 7, FIG. 8, and FIG. 11, the circuit board 3 is arranged at a side of at least part of the vibration plate 1, and the circuit board 3 and the at least part of the vibration plate 1 have a gap G therebetween. Moreover, a first projected region defined by orthogonally projecting the circuit board 3 onto the first plane (e.g., the top surface of the vibration plate 1 shown in FIG. 11) partially covers the at least part of the vibration plate 1. In other words, the circuit board 3 is approximately spaced apart from (or located at) one side of the vibration plate 1 (e.g., the upper side of the vibration plate 1 shown in FIG. 11) away from the carrier 6 or the aerosol chamber 202. That is to say, the circuit board 3 in the present embodiment is arranged directly above the vibration plate 1.

Specifically, the circuit board 3 and the vibration plate 1 in the present embodiment can be spaced apart from each other by at least one of the buffer 5 and the solders 4, and are described in further detail in the following description. In addition, since the circuit board 3 has a positioning portion 34 fastened to the container 200, the circuit board 3 can be spaced apart from the side of the at least part of the vibration plate 1 by the cooperation of the container 200 and the positioning portion 34, but the present disclosure is not limited thereto.

For example, in other embodiments of the present disclosure, the circuit board 3 and the vibration plate 1 can be provided without any structural support or connection therebetween. In other words, the circuit board 3 can be positioned over the at least part of the vibration plate 1 only by the cooperation of the container 200 and the positioning portion 34.

The circuit board 3 in the present embodiment is in a substantially annular shape, but the shape and size of the circuit board 3 can be adjusted according to design requirements. For example, the circuit board 3 can be a structure as shown in FIG. 12.

As shown in FIG. 7, FIG. 8, and FIG. 11, the circuit board 3 is electrically coupled to the two electrical contacts 15a, 15b of the vibration plate 1. In the present embodiment, the circuit board 3 is electrically coupled to the two electrical contacts 15a, 15b by the solders 4 (e.g., two solder balls), and the solders 4 are fixed to the electrical contacts 15a, 15b and the circuit board 3 so as to establish an electrical connection between the electrical contacts 15a, 15b and the circuit board 3, but the present disclosure is not limited thereto. In other embodiments of the present disclosure, the circuit board 3 can be electrically coupled to the two electrical contacts 15a, 15b by cables.

The circuit board 3 includes two adjacent conductive portions 31 spaced apart from each other and two conductive circuits 32 respectively connected to the two conductive portions 31. The two conductive portions 31 have different polarities, and each of the two conductive portions 31 has two electrode regions 311a, 311b. The two electrode regions 311a, 311b of one of the two conductive portions 31 are respectively arranged adjacent to the two electrode regions 311a, 311b of the other conductive portion 31. The two conductive portions 31 are respectively and electrically coupled to the two electrical contacts 15a, 15b through the conductive circuits 32 and the solders 4. The two conductive circuits 32 in the present embodiment preferably have different lengths.

Moreover, the number of the conductive portions 31 (or the electrode regions 311a, 311b) and the number of the conductive circuits 32 of the circuit board 3 can be adjusted according to design requirements. For example, in other embodiments of the present disclosure, the circuit board 3 can include only one conductive portion 31 and only one conductive circuit 32 connected to the conductive portion 31; or the circuit board 3 can include only one of the electrode regions 311a, 311b and only one conductive circuit 32 connected to the electrode region 311a, 311b; or the circuit board 3 can include only one electrode region 311a, 311b, and the one of the electrode regions 311a, 311b is directly connected to the corresponding electrical contact 15a, 15b or is electrically coupled to the corresponding electrical contact 15a, 15b by a cable.

Specifically, as shown in FIG. 7, FIG. 8, and FIG. 11, each of the electrode regions 311a, 311b is arranged on a surface of the circuit board 3 (e.g., the top surface of the circuit board 3 shown in FIG.8) away from the vibration plate 1. Portions of the first projected region with respect to the electrode regions 311a, 311b are located outside of the electrical contacts 15a, 15b. That is to say, the portions of the first projected region defined by orthogonally projecting the electrode regions 311a, 311b onto the first plane (e.g., the top surface of the vibration plate 1 shown in FIG. 7) are located outside of the electrical contacts 15a, 15b. In other words, as shown in FIG. 11, at least part of each of the electrode regions 311a, 311b is substantially arranged above a portion of at least one of the middle segment 13 and the outer segment 14 of the vibration plate 1 that is not formed with the electrical contacts 15a, 15b.

The circuit board 3 includes two externally connecting arms 33 hung over and arranged directly above at least one of the middle segment 13 and the outer segment 14 of the vibration plate 1. Free ends of the two externally connecting arms 33 in the present embodiment are approximately and respectively arranged above the two electrical contacts 15a, 15b of the vibration plate 1, so that the free end of each of the two externally connecting arms 33 can swing slightly and elastically. In addition, in other embodiments of the present disclosure, the circuit board 3 can be formed with only one externally connecting arm 33 or no externally connecting arm 33.

Moreover, each of the two conductive circuits 32 has a first end and an opposite second end. The first ends of the two conductive circuits 32 are respectively connected to the two conductive portions 31 of the circuit board 3, and the second ends of the two conductive circuits 32 are respectively arranged on the free ends of the two externally connecting arms 33. The two solders 4 connected to the two electrical contacts 15a, 15b are respectively soldered to the two externally connecting arms 33, thereby electrically connecting to the conductive circuits 32 on the externally connecting arms 33. The circuit board 3 can absorb a deviation generated from a soldering process of the solders 4 by the swing function of each of the externally connecting arms 33, thereby effectively preventing empty soldering from occurring to the solders 4.

As shown in FIG. 8 and FIG. 11, the two electrode regions 311a, 311b of each of the conductive portions 31 are located on a second plane (e.g., the top surface of the circuit board 3 shown in FIG. 11), and the central axis C2 of the aerosol chamber 202 is substantially perpendicular to the second plane (as shown in FIG. 2 and FIG. 11). Moreover, each of the conductive portions 31 in the present embodiment further includes another electrode region 311c. In the two electrode regions 311a, 311c of each of the conductive portions 31, one of the two electrode regions 311a, 311c (i.e., the electrode region 311a) is located on the second plane (e.g., the top surface of the circuit board 3 shown in FIG. 11) that is substantially perpendicular to the central axis C2, and the other electrode region 311c is located on a third plane other than the first and second planes. The two electrode regions 311a, 311c have an angle that is within a range of 70˜110 degrees therebetween.

It should be noted that, the arrangement of the electrode region 311c can be adjusted according to design requirements. In the present embodiment, the electrode region 311c of each of the conductive portions 31 is disposed on/around an outer surface of the electronic component 7. Specifically, the electronic component 7 is disposed on the surface (e.g., the top surface) of the circuit board 3 away from the vibration plate 1, and is straddled onto the electrode regions 311b of the two conductive portions 31, so that the two electrode regions 311c on the electronic component 7 are respectively connected to the two electrode regions 311b on the top surface of the circuit board 3 so as to establish the electrical connection therebetween. Accordingly, the electrode regions 311a of the two conductive portions 31 not covered by the electronic component 7 are arranged on the top surface of the circuit board 3 (or are located on the second plane), and the two electrode regions 311a, 311c of each of the two conductive portions 31 have an angle athat is within a range of 70˜110 degrees therebetween. The angle a in the present embodiment is 90 degrees, but the present disclosure is not limited thereto.

The electrode regions 311a, 311b, 311c in the present embodiment are formed on the circuit board 3 and the electronic component 7, but the position and number of the electrode regions 311a, 311b, 311c can be adjusted according to design requirements. For example, in other embodiments of the present disclosure, the atomizing module 100 can exclude the electronic component 7 and the electrode regions 311c, so that all of the electrode regions 311a, 311b of the conductive portions 31 are located on the same plane (e.g., the second plane); or each of the conductive portions 31 of the atomizing module 100 can include only two electrode regions 311a, 311c that are located on different planes (e.g., the second plane and the third plane); or the atomizing module 100 can exclude the circuit board 3, and the electrical contacts 15a, 15b of the vibration plate 1 are used as electrode regions.

As shown in FIG. 11, the top surface of the circuit board 3 (e.g., the second plane) and the insertion direction S of the insertion slot 204 of the container 200 have an acute angle 6 that is within a range of 30˜60 degrees therebetween. Moreover, a second projected region defined by a projection of the thru-hole 2041 onto the atomizing module 100 along the insertion direction S is located on the two electrode regions 311a, 311c of each of the conductive portions 31.

However, an angle between the top surface of the circuit board 3 and the insertion direction S of the insertion slot 204 in the present embodiment is within a range of 30˜60 degrees, but the present disclosure is not limited thereto. In other embodiments of the present disclosure, an angle between the top surface of the circuit board 3 and the insertion direction S of the insertion slot 204 can be other values (e.g., 90 degrees).

As shown in FIG. 7, FIG. 8, and FIG. 11, the buffer 5 in the present embodiment is a solidified adhesive, but the present disclosure is not limited thereto.

Moreover, the middle segment 13 and the outer segment 14 each have a surface facing the vibration plate 1, and 3˜30% of the surfaces of the middle segment 13 and the outer segment 14 are connected to the buffer 5.

In other embodiments of the present disclosure, a space between the circuit board 3 and the vibration plate 1 can be provided without the buffer 5, can be provided with a plurality of buffers 5, or can be fully filled with the buffer 5 according to design requirements.

The bottom gasket 8 includes an annular sheet 81, a plurality of annular ribs 82 respectively extending from two opposite surfaces of the annular sheet 81, and an annular flange 83 extending from an outer lateral edge of the annular sheet 81.

In a top view of the bottom gasket 8, the annular ribs 82 and the annular flange 83 are concentric circles, and any two of the annular ribs 82 adjacent to each other have the same gap. A height of each of the annular ribs 82 with respect to the annular sheet 81 is smaller than a height of the annular flange 83 with respect to the annular sheet 81, but the present disclosure is not limited thereto.

Moreover, the bottom gasket 8 is disposed on the cover 200b of the container 200, the annular ribs 82 are sandwiched between the carrier 6 and the cover 200b of the container 200 (i.e., the carrier 6 is disposed on the annular ribs 82), the annular flange 83 is sandwiched between and gaplessly connected to the cup 200a and the cover 200b of the container 200, and a center of the bottom gasket 8 is substantially located on the central axis C2 of the aerosol chamber 202 (as shown in FIG. 2).

Specifically, as shown in FIG. 11, a third projected region defined by orthogonally projecting the annular ribs 82 onto the vibration plate 1 is substantially located on at least one of the middle segment 13 and the outer segment 14. Accordingly, the bottom gasket 8 can provide a buffering effect between the vibration plate 1 and the portion of the circuit board 3 having the electrode regions 311a, 311b, 311c by the annular ribs 82, so that the electrode regions 311a, 311b, 311c of the circuit board 3 can receive a larger pressing force.

As shown in FIG. 8 and FIG. 10, the inner gasket 9 in the present embodiment is an annular structure (e.g., an annular rubber) with a resilient property. The inner gasket 9 has a hole defined by an inner edge thereof, and a diameter of the hole of the inner gasket 9 is smaller than that of the first hole 11 of the vibration plate 1. The inner gasket 9 includes a main annular body 91 and an abutting annular body 92 slantingly extending from an inner edge of the main annular body 91.

Moreover, the main annular body 91 is disposed on a part of the inner segment 12 of the vibration plate 1 (e.g., an inner part of the inner segment 12 protruding from the circuit board 3 as shown in FIG. 10), and the main annular body 91 is partially arranged in a hole defined by an inner edge of the circuit board 3. The main annular body 91 in the present embodiment is sandwiched between the cup 200a of the container 200 and the vibration plate 1, so that the main annular body 91 can be approximately and gaplessly connected to the cup 200a of the container 200. The abutting annular body 92 is arranged in the first hole 11 of the vibration plate 1, and a free end of the abutting annular body 92 abuts against the microporous member 2.

As shown in FIG. 3 and FIG. 14, the plug 2000 is detachably inserted into the insertion slot 204 of the container 200 along the insertion direction S, and is electrically coupled to the circuit board 3. The plug 2000 in the present embodiment includes an insulator 2001 and two conductive terminals 2002 each partially embedded in the insulator 2001, and the conductive terminals 2002 are respectively abutted against the two conductive portions 31 of the circuit board 3.

Specifically, each of the conductive terminals 2002 detachably passes through the thru-hole 2041 of the insertion slot 204 and elastically abuts against the two electrode regions 311a, 311c of the corresponding conductive portion 31. Each of the conductive terminals 2002 of the plug 2000 in the present embodiment can simultaneously abut against the corresponding two electrode regions 311a, 311c, thereby increasing the stability of electrical connection between the circuit board 3 and each of the conductive terminals 2002. Moreover, the plug 2000 is electrically coupled to the vibration plate 1 through the circuit board 3 and the solders 4, thereby preventing the vibration of the vibration plate 1 from affecting the stability of electrical connection between the circuit board 3 and the plug 2000.

As shown in FIG. 15, each of the two electrode regions 311a, 311c can receive a pressing force F from the corresponding conductive terminal 2002, and the pressing force F has a horizontal component Fx and a vertical component Fy. Specifically, a portion of each of the two electrode regions 311a, 311c abutted against the conductive terminal 2002 is substantially arranged above at least one of the middle segment 13 and the outer segment 14 of the vibration plate 1, and is substantially arranged above the annular ribs 82 of the bottom gasket 8, so that the buffer 5 and the annular ribs 82 can absorb the pressing force F of the vertical component Fy from the electrode regions 311a (or the terminals 2002).

The number of the conductive terminals 2002 of the plug 2000 in the present embodiment is two, but the present disclosure is not limited thereto. In other embodiments of the present disclosure, the plug 2000 can include only one conductive terminal 2002 that passes through the thru-hole 2041 of the insertion slot 204 and that is elastically abutted against the corresponding two electrode regions 311a, 311c.

It should be noted that, the aerosol generating device of the present embodiment can be adjusted according to other embodiments of the present disclosure. That is to say, the aerosol generating device provided by the present disclosure can be formed of any combination of the features disclosed in the present embodiment and other embodiments.

In conclusion, in the aerosol generator and the atomizing module of the present disclosure, the circuit board is spaced apart from and is electrically coupled to the vibration plate, so that the conductive terminal needs to abut against the circuit board to be further electrically coupled to the vibration plate. Accordingly, the electrical connection between the circuit board and the conductive terminal is not easily affected by the vibration generated from the vibration plate, thereby being more stable.

Moreover, in the aerosol generating device and the aerosol generator of the present disclosure, the atomizing module is provided with the two electrode regions electrically connected to each other and having the same polarity, and the conductive terminal is simultaneously abutted against the two electrode regions to form a multi-point contact, so that the electrical connection between the circuit board (or the vibration plate) and the conductive terminal can be more stable.
