Referring to fig. 4, fig. 4 is a schematic structural diagram of the micro-orifice atomizing assembly provided in fig. 2.
In one embodiment, the microporous atomization sheet 10 is a ceramic atomization sheet. The microporous atomization sheet 10 includes a piezoelectric ceramic sheet 11 and a metal substrate 12 which are stacked. The surface of the piezoelectric ceramic plate 11 away from the metal substrate 12 is provided with a first electrode layer, and the electrode layer is usually made of a material with high conductivity, such as a metal material containing silver, copper, and the like. A second electrode layer can also be arranged on the surface of one side of the piezoelectric ceramic piece 11 close to the metal substrate 12; and extending the second electrode layer to the plane of the first electrode layer. This has the advantage that the two flexible conductors 30 can be arranged on the same side to electrically connect the positive and negative electrodes. In other embodiments, the metal substrate 12 may be used as another electrode in conjunction with the first electrode layer. The circuit board 20 and the flexible conductor 30 are disposed on the surface of the piezoceramic sheet 11 remote from the metal substrate 12.
Specifically, as shown in fig. 3 and fig. 4, the piezoelectric ceramic plate 11 is ring-shaped, for example, circular ring-shaped, the metal substrate 12 covers the through hole of the ring-shaped piezoelectric ceramic plate 11, the center of the metal substrate 12 has a protruding portion 122, the protruding portion 122 protrudes toward the piezoelectric ceramic plate 11 and is exposed through the through hole of the piezoelectric ceramic plate 11, and the protruding portion 122 has a plurality of micropores as the atomizing holes 121 of the microporous atomizing plate 10.

As shown in fig. 2 and fig. 11, fig. 11 is a schematic structural diagram of a circuit board according to an embodiment of the present disclosure.
The circuit board 20 may be a PCB or an FPC, in this embodiment, the circuit board 20 is a PCB, and the PCB is connected to the micro-porous atomizing sheet 10 through the flexible conductor 30 to realize flexible electrical connection with the micro-porous atomizing sheet 10. In this embodiment, the circuit board 20 is an arc-shaped PCB, and is disposed entirely on the surface of the piezoelectric ceramic plate 11. The circuit board 20 has a positive contact and a negative contact, a flexible conductor 30 is arranged between the positive contact and the piezoelectric ceramic plate 11, another flexible conductor 30 is arranged between the negative contact and the piezoelectric ceramic plate 11, and the materials, shapes and volumes of the two flexible conductors 30 are completely the same. The outer diameter of the circuit board 20 is substantially flush with the outer diameter of the microporous atomization sheet 10, i.e., the outer diameter of the PCB may be just flush with the outer diameter of the microporous atomization sheet 10, or may be slightly larger or shorter than the outer diameter of the microporous atomization sheet 10, as long as it does not exceed the outer sidewall of the clamping assembly 40. In other embodiments, the circuit board 20 may also be a flexible circuit board, and is partially bent to the side of the microporous atomization sheet 10. Meanwhile, the PCB may have other shapes as long as the PCB can be connected to the micro-porous atomization sheet 10 in a matching manner, which is not limited in the present application.
The flexible electrical connection between the circuit board 20 and the microporous atomization sheet 10 is different from rigid connection and welding, and refers to a connection manner in which the circuit board 20 and the microporous atomization sheet 10 are connected by a flexible material without welding, so that the joint between the circuit board 20 and the microporous atomization sheet 10 can be elastically deformed within a certain range. In another prior art, the electrical signal of the microporous atomization sheet 10 is transmitted to the microporous atomization sheet 10 through the metal elastic thimble to make elastic contact with the microporous atomization sheet 10, and the acting force on the microporous atomization sheet 10 is large, so that the electrical parameter of the microporous atomization sheet 10 deviates from the theoretical value, such as the impedance value becomes large, the waveform is disordered, and the resistance value becomes high. In addition, when the microporous atomization sheet 10 works, the metal elastic thimble is in a static state, the microporous atomization sheet 10 is in a high-frequency vibration state, a protective layer on the top of the metal elastic thimble is easy to wear and oxidize, and the service life of the whole machine is greatly shortened. This application adopts flexible electric connection mode can greatly cushion the power that micropore atomizing piece 10 vibration atomizing produced for the power that acts on at micropore atomizing piece can be ignored, has solved above-mentioned technological problem well. Meanwhile, the process of welding wires by an electric soldering iron is omitted, so that the assembly is simpler and the cost is lower. In the prior art, the electric signal of the micropore atomization sheet 10 is transmitted to the ceramic sheet through a welding wire, when the wire is welded, the temperature of an electric soldering iron, the heating time and the diameter and height of a bonding pad are directly related to the electrical performance parameters of the micropore atomization sheet 10, such as the resistance value is increased, the waveform is disordered, the resistance value is increased, and the electrical performance parameters are directly related to the atomization amount of a product and the size of atomized particles. Meanwhile, the factors of the temperature of the electric soldering iron, the welding time and the size and height of the bonding pad are not controllable during manual operation, the experience requirement on operators is high, and the consistency during batch production is difficult to guarantee.
In one embodiment, as shown in fig. 2, the flexible conductive body 30 is a conductive sheet made of a flexible conductive material, which may be flexible conductive rubber, conductive foam, or other flexible glue. The flexible conductive body 30 can be fixedly connected with the circuit board 20 and the micro-porous atomizing sheet 10 by the viscosity of the flexible conductive body itself, or can be fixedly connected with the circuit board 20 and the micro-porous atomizing sheet 10 by arranging an adhesive layer. The circuit board 20 and the microporous atomization sheet 10 are fixedly connected through the adhesive of the flexible electric conductor 30 or the adhesive layer on the surface of the flexible electric conductor 30. Because the flexible conductor 30 is made of flexible material, it can connect the circuit board 20 and the microporous atomization sheet 10 more firmly, and make the microporous atomization sheet 10, the circuit board 20 and the flexible conductor 30 elastically deform to a certain extent. Wherein the adhesive layer may be a conductive adhesive. In other embodiments, a limiting groove or a limiting rib may be disposed on the circuit board 20 or the clamping assembly 4 to fix the flexible electrical conductor 30. The flexible conductor 30 may also be fixed between the circuit board 20 and the microporous atomization sheet 10 by means of a friction force generated by elastic deformation of the flexible conductor.
In one embodiment, as shown in fig. 2 and 3, the clamping assembly 40 is used to clamp the circuit board 20 and the microporous atomization sheet 10 to achieve a secure connection between the circuit board 20 and the microporous atomization sheet 10. The clamping assembly 40 includes a first rigid mount 41, a second rigid mount 42, a first flexible mount 43, and a second flexible mount 44. The first rigid fixing member 41, the second rigid fixing member 42, the first flexible fixing member 43 and the second flexible fixing member 44 are all annular bodies, and the plurality of atomization holes 121 are exposed through holes of the annular bodies, so that the aerosol can pass through the through holes of the annular bodies. The first rigid fixing member 41 is disposed on one side of the microporous atomization sheet 10, the second rigid fixing member 42 is disposed on the other side of the microporous atomization sheet 10, and the second rigid fixing member 42 and the first rigid fixing member 41 cooperate to clamp the circuit board 20 and the microporous atomization sheet 10. The first flexible fixing member 43 is disposed between the first rigid fixing member 41 and the microporous atomization sheet 10, the second flexible fixing member 44 is disposed between the second rigid fixing member 42 and the microporous atomization sheet 10, and both the first flexible fixing member 43 and the second flexible fixing member 44 are used for buffering the force generated by the vibration between the first rigid fixing member 41 or the second rigid fixing member 42 and the circuit board 20 and the microporous atomization sheet 10. The surface and the side surface of the microporous atomization sheet 10 are fixed in the first flexible fixing piece 43 and the second flexible fixing piece 44, so that the natural frequency is kept to vibrate in the circumferential direction and the radial direction without attenuation, and the atomization effect of the microporous atomization sheet 10 is not influenced.
Specifically, the circuit board 20 is disposed between the micro-porous atomization sheet 10 and the first rigid fixing member 41, and one side of the circuit board 20 is fixed to the micro-porous atomization sheet 10 by the first rigid fixing member 41. The first rigid fixing member 41 and the second rigid fixing member 42 are both ring-shaped bodies and are made of rigid fixing materials, such as ceramics, steel, iron, and the like. The first rigid fixing member 41 and the second rigid fixing member 42 are detachably fixed by means of buckling, clamping or screws, which on one hand facilitates the detachment, and on the other hand, the positions of the circuit board 20 and the microporous atomization sheet 10 are relatively and fixedly maintained within the range formed after the first rigid fixing member 41 and the second rigid fixing member 42 are connected, thereby avoiding a large displacement between the circuit board 20 and the microporous atomization sheet 10.
Referring to fig. 3, 5 and 6, fig. 5 is a first perspective structural view of the first rigid fixing member provided in fig. 2; figure 6 is a second perspective view of the first rigid mount provided in figure 2.
The first rigid mount 41 includes a coaxially disposed first annular body 410, a first collar 4111, and a second collar 4121. The first annular body 410 has a first surface 411 and a second surface 412 disposed opposite to each other, the first surface 411 is a surface far away from the microporous atomization sheet 10, and the second surface 412 is a surface close to the microporous atomization sheet 10. The first ring 4111 protrudes away from the first surface 411, the second ring 4121 protrudes away from the second surface 412, and the first ring 4111 and the second ring 4121 protrude in opposite directions and are annular. The first raised ring 4111 has the same inner diameter as the first annular body 410 to facilitate egress of an aerosol substrate produced from the microporous atomizing sheet 10. The outer diameter of the second male ring 4121 is the same as the outer diameter of the first annular body 410. In this embodiment, it is preferable that the second protruding ring 4121 can extend along the outer diameter of the first annular body 410 away from the second surface 412 to a position where it meets the second rigid fixing member 42, so as to make the connection between the first rigid fixing member 41 and the second rigid fixing member 42 tighter, thereby improving the stability of the micro-porous atomization assembly 1. In other embodiments, the second collar 4121 may extend radially outward of the first annular body 410 away from the second surface 412 or may extend only to the end of the outer diameter of the first annular body 410. The extending position and the extending direction of the second protruding ring 4121 may also be set as needed, which is not limited in this application.
Optionally, the second surface 412 of the first annular body 410 has a second groove 4122 for accommodating the first flexible fixing member 43, so that vibration generated when the microporous atomization sheet 10 atomizes the aerosol-generating substrate is greatly reduced when being transmitted to the first rigid fixing member 41 through the first flexible fixing member 43, and the vibration is buffered through the first flexible fixing member 43, so that vibration generated by the microporous atomization sheet 10 is not reduced immediately when encountering the first rigid fixing member 41, but is gradually reduced through the first flexible fixing member 43, which not only can avoid the problem that the vibrating force generated by the microporous atomization sheet 10 directly frequently strikes the first rigid fixing member 41 to cause abrasion and oxidation of the microporous atomization sheet 10, which affects the service life of the microporous atomization sheet 10, but also can not affect the atomization effect of the microporous atomization sheet 10.
Referring to fig. 2, fig. 3, fig. 7 and fig. 8, fig. 7 is a schematic view of a first perspective structure of the second rigid fixing member provided in fig. 2; fig. 8 is a second perspective view of the second rigid mount provided in fig. 2.

The third surface 421 contacts and connects to the second collar 4121 of the first rigid retainer 41 on the side near the outer diameter of the second annular body 420. The third surface 421 has a third convex ring 423, and the third convex ring 423 protrudes to a direction close to the first rigid fixing member 41. The second rigid mount 42 has a first through hole 4231, the first through hole 4231 passing through the second annular body 420 and the third male ring 423. Preferably, the third surface 421 further has a third groove 4211, the third groove 4211 is used for connecting the second flexible fixing element 44, and the second flexible fixing element 44 is correspondingly provided with a fourth protruding ring 444, and the fourth protruding ring 444 is matched and connected with the third groove 4211, so as to enhance the connection stability of the second flexible fixing element 44 and the second rigid fixing element 42. It is understood that third groove 4211 may be formed in second flexible fastener 44 and fourth collar 444 may be formed on third surface 421, so long as the mating connection of second flexible fastener 44 to second rigid fastener 42 is achieved. In other embodiments, the third groove 4211 and the fourth convex ring 444 in the present application may not be provided, and the present application is not limited thereto.
Specifically, the second protruding ring 4121 of the first rigid fixing member 41 has a plurality of hooks 424 on a side thereof close to the second flexible fixing member 44, and the plurality of hooks 424 are used for connecting the micro-porous atomizing sheet 10 and a temperature sensor (not shown). The specific size of the buckle 424 can be set as required, as long as the matching connection with the micropore atomization sheet 10, the temperature sensor and other components can be realized, and the application does not limit the size.
Optionally, an annular sealing member 45 is disposed at a joint of the first rigid fixing member 41 and the second rigid fixing member 42, and the sealing member 45 is disposed at the joint of the first rigid fixing member 41 and the second rigid fixing member 42 in an attaching manner to seal a gap at the joint, so that the first rigid fixing member 41 and the second rigid fixing member 42 are connected more tightly, and stability of the micro-pore atomizing assembly 1 is improved. In this embodiment, the sealing member 45 may be made of a flexible material, such as: the sealing performance of the connection between the first rigid fixing member 41 and the second rigid fixing member 42 can be improved by soaking cotton or rubber, and the structure of the first rigid fixing member 41 and the second rigid fixing member 42 can not be extruded, so that the whole position of the clamping assembly 40 is prevented from moving.
Optionally, the fourth surface 422 of the second rigid fixing member 42 has a first indent 4221 and an annular recess 4222, the first indent 4221 extends from the fourth surface 422 towards the third surface 421, and a bottom wall of the first indent 4221 is communicated with the first through hole 4231.
