Please refer to fig. 1, which is a schematic structural diagram of the microporous atomizing sheet of the present invention. Wherein, the micropore atomization sheet 100 comprises a piezoelectric ceramic sheet 10, and when the micropore atomization sheet 100 is used for atomization, voltage needs to be applied to two surfaces of the piezoelectric ceramic sheet 10 by using an electrode, so that the micropore atomization sheet vibrates, and the atomization substrate is atomized.

Specifically, please refer to fig. 2, which is a schematic structural diagram of the microporous atomization sheet shown in fig. 1 according to the first embodiment. The microporous atomization sheet 100 includes a piezoelectric ceramic sheet 10, a first conductive layer 12, and a second conductive layer 11. The first conductive layer 12 is stacked with the piezoelectric ceramic plate 10 and located on a first side of the piezoelectric ceramic plate 10. The second conductive layer 11 is stacked with the piezoelectric ceramic plate 10 and located on a second side of the piezoelectric ceramic plate 10 away from the first conductive layer 12. In order to atomize the atomizing substrate, the first conductive layer 12 or the second conductive layer 11 has atomizing holes. This embodiment will be described by taking an example in which the second conductive layer 11 has an atomization hole. Specifically, in order to apply a voltage to both surfaces of the piezoelectric ceramic sheet 10 to cause the piezoelectric ceramic sheet to vibrate, conductive electrodes need to be provided for the first conductive layer 12 and the second conductive layer 11 on both sides of the piezoelectric ceramic sheet 10. In this embodiment, the first conductive layer 12 extends to the second side of the piezoelectric ceramic plate 10 (i.e., the side where the second conductive layer 11 is located) along the sidewall of the piezoelectric ceramic plate 10, so that the portion of the first conductive layer 12 located at the second side of the piezoelectric ceramic plate 10 is used for abutting against the first pogo pin, the second conductive layer 11 is directly used for abutting against the second pogo pin at the second side of the piezoelectric ceramic plate 10, the first pogo pin and the second pogo pin are both disposed at the second side of the piezoelectric ceramic plate 10 and electrically connected to the power supply, and the power supply applies voltage to the first conductive layer 12 and the second conductive layer 11 through the first pogo pin and the second pogo pin.

Specifically, in an embodiment, the piezoelectric ceramic plate 10 is circular, as shown in fig. 2, in another embodiment, the piezoelectric ceramic plate 10 may also be square, trapezoid, etc., and it should be noted that, regardless of the shape of the piezoelectric ceramic plate 10, the center thereof has a position of the annular through hole where the atomization hole is exposed. The present application will be described by taking the piezoelectric ceramic sheet 10 as a circular shape. The first conductive layer 12 includes a body portion 121 and an extension portion 122. The extension portion 122 is connected to the main body portion 121 and extends to the second side of the piezoceramic wafer 10 along the sidewall of the piezoceramic wafer 10, and the extension portion 122 is used for abutting against the first pogo pin. Further, the extension portion 122 includes a wrapping portion 123 and an abutting portion 124, the wrapping portion 123 is connected to the main body portion 121 and wraps a part of the side wall of the piezoelectric ceramic plate 10, the abutting portion 124 is connected to the wrapping portion 123 and disposed on the second side of the piezoelectric ceramic plate 10, and the abutting portion 124 is used for abutting against the first pogo pin. In this embodiment, the second conductive layer 11 serves as a carrier of the atomization holes, and thus the main body portion 121 of the first conductive layer 12 has a circular ring shape. In one embodiment, the main portion 121 of the first conductive layer 12 completely coincides with the projection of the piezoceramic sheet 10 in the vertical direction. That is, the body 121 of the first conductive layer 12 and the piezoelectric ceramic sheet 10 have the same shape and size and are completely overlapped. It is understood that the size of the main body 121 of the first conductive layer 12 may also be slightly smaller or larger than the size of the piezoceramic sheet 10, for example, the inner diameter of the main body 121 of the first conductive layer 12 is larger than the inner diameter of the piezoceramic sheet 10, and the outer diameter is smaller or equal to the outer diameter of the piezoceramic sheet 10; or the inner diameter of the main body part 121 of the first conductive layer 12 is smaller than or equal to the inner diameter of the piezoceramic sheet 10, and the outer diameter is smaller than the outer diameter of the piezoceramic sheet 10. The shapes of the wrapping portion 123 and the abutting portion 124 are not limited, and may be designed as necessary.

In one embodiment, the extension portion 122 of the first conductive layer 12 is integrally formed with the main body portion 121, and may be a self-supporting metal layer, such as a metal layer formed by a sheet metal process, and the metal may be a conductive material such as copper, aluminum alloy, stainless steel, and the like. The self-supporting property means that the metal layer may be separated from the support and exist independently, or may be detached from the support to be distinguished from the metal layer formed by the plating process. Specifically, the extension portion 122 and the main body portion 121 of the first conductive layer 12 are copper foils. In order to prevent the first conductive layer from being worn and broken during the voltage application process, the thickness of the first conductive layer 12 is 0.1-0.5 mm. Specifically, the thickness of the extension portion 122 and the thickness of the main body portion 121 are both 0.1-0.5 mm.

In an embodiment, the second conductive layer 11 has an opening 111 at a position corresponding to the abutting portion 124, and the abutting portion 124 is attached to a portion of the surface of the piezoelectric ceramic plate 10 exposed through the opening 111 and insulated from the second conductive layer 11. Specifically, as shown in fig. 2, the extension portion 122 is used to lead the electrode on the upper surface of the piezoceramic sheet 10 (i.e. the main portion 121 of the first conductive layer 12) to one side of the second conductive layer 11, so as to facilitate installation with a power supply. Specifically, the outline of the opening 111 may be any shape, such as rectangular, arc, trapezoid, and the like. The opening 111 may be an arc-shaped notch or a through hole at the edge of the second conductive layer 11. Preferably, the opening 111 is an arc notch located at the edge of the second conductive layer 11, and has a shape corresponding to the abutting portion 124 and a size larger than that of the abutting portion 124, so that the area of the opening 111 can be reduced when the pogo pin is abutted, and the imbalance of the first conductive layer 12 during vibration can be reduced. The abutting portion 124 and the second conductive layer 11 may be directly insulated from each other by another method, for example, an insulating layer may be provided between the abutting portion 124 and the second conductive layer 11.

In one embodiment, the thickness of the second conductive layer 11 is 0.1 to 0.5mm, which is the same as the thickness of the first conductive layer 12, and the material of the second conductive layer 11 is the same as the material of the first conductive layer 12, such as copper, aluminum alloy, stainless steel, and other conductive materials.

Specifically, in this embodiment, since the first pogo pin and the second pogo pin connection position are both located on one side of the second conductive layer 11, in this embodiment, the second conductive layer 11 is provided with the positioning portion 113 by staggering the edge positions of the first pogo pin and the second pogo pin, so as to ensure that the first pogo pin abuts against the abutting portion 124 of the first conductive layer 12, and the second pogo pin abuts against the second conductive layer 11. Specifically, in an embodiment, the positioning portion 113 is a protrusion or a groove.

Further, since the first conductive layer 12 and the second conductive layer 11 of the present application have self-supporting properties, they need to be fixed on the first side and the second side of the piezoceramic sheet 10, and in a specific embodiment, they may be welded by means of welding, or they may be adhered by using an adhesive glue. Thus, as shown in fig. 2, the microporous atomization sheet 100 further includes: a first adhesive layer 13 and a second adhesive layer 14, wherein the first adhesive layer 13 is located between the first conductive layer 12 and the piezoceramic sheet 10 to bond the first conductive layer 12 and the piezoceramic sheet 10. The second adhesive layer 14 is located between the second conductive layer 11 and the piezoceramic sheet 10 to bond the second conductive layer 11 and the piezoceramic sheet 10. It is understood that first adhesive layer 13 and second adhesive layer 14 are both circular in shape. As shown in fig. 2, second adhesive layer 14 also has a corresponding opening at a location corresponding to opening 111. Both the first adhesive layer 13 and the second adhesive layer 14 are conductive adhesives.

In this embodiment, the second conductive layer 11 has an atomizing hole 112, specifically, the second conductive layer 11 is in a shape of a circular disc and covers the central through hole of the piezoelectric ceramic sheet 10, and the atomizing hole 112 is located in a portion of the second conductive layer 11 corresponding to the central through hole of the piezoelectric ceramic sheet 10, specifically as shown in fig. 2, that is, the atomizing hole 112 is exposed by the piezoelectric ceramic sheet 10. The atomization holes 112 may be one or any combination of conical, rectangular, circular. In one embodiment, the atomization holes 112 are tapered.

In another embodiment, please refer to fig. 3 specifically, which is a schematic structural diagram of a microporous atomization sheet shown in fig. 1 according to a second embodiment. The second conductive layer 11 has a protrusion 114 corresponding to the central through hole of the piezoceramic sheet 10, and the atomization holes 112 are distributed on the protrusion 114. The protrusion 114 is one or any combination of a spherical surface shape and a trapezoid shape. It should be noted that the direction of projection of the projections 114 is preferably the direction of flow of the aerosolized matrix.

Fig. 4 is a schematic structural diagram of a microporous atomization sheet shown in fig. 1 according to a third embodiment. In this embodiment, the main portion 121 and the extension portion 122 of the first conductive layer 12 are integrally formed. Compared with the second embodiment shown in fig. 3, the difference is that in this embodiment, the first conductive layer 12 is directly formed on the surface of the piezoceramic sheet 10 by deposition or coating. For example, in the present embodiment, the first conductive layer 12 is a metal layer formed on the surface of the piezoelectric ceramic plate 10 by silver spraying, screen printing, electroplating, thermal deposition, chemical vapor deposition, sputtering, and the like. In one embodiment, the material of the first conductive layer 12 is conductive silver paste.

Specifically, the thickness of the first conductive layer 12 is 0.05 to 0.1mm, and the main body portion 121 and the extension portion 122 of the first conductive layer 12 are integrally formed, that is, the thicknesses of the main body portion 121, the wrapping portion 123 and the abutting portion 124 are all 0.05 to 0.1mm, so that the abutting portion 124 is thin. In order to prevent the abutting portion 124 of the first conductive layer 12 from being worn by the pogo pin to cause a failure problem, a metal plate 15 is further provided on the surface of the abutting portion 124 away from the piezoceramic sheet 10, the metal plate 15 being used to abut against the first pogo pin. Specifically, the metal sheet 15 may be welded or fixed on the surface of the abutting portion 124 away from the piezoelectric ceramic sheet 10 by an adhesive, and the metal sheet 15 may be a copper sheet, an aluminum sheet, or the like, and has a thickness of 0.1 to 0.5 mm.

It should be noted that, since the first conductive layer 12 is directly deposited or coated on the piezoceramic sheet 10 in this embodiment, an adhesive layer is not required to be disposed between the first conductive layer 12 and the piezoceramic sheet 10, but only the third adhesive layer 16 is disposed between the second conductive layer 11 and the piezoceramic sheet 10, and the third adhesive layer 16 is used to bond the second conductive layer 11 and the piezoceramic sheet 10. The third adhesive layer 16 has the same structure as the second adhesive layer 14 shown in fig. 3, and detailed description thereof is omitted.

Specifically, the attaching portion 125 may be welded to the surface of the main body portion 121 by a welding method, and the attaching portion 124 may be adhered to the surface of the second conductive layer 11 away from the piezoelectric ceramic plate 10 by glue.

In another embodiment, the first conductive layer 12 may also be a self-supporting metal sheet bonded to the first side of the piezoceramic sheet by an adhesive layer, which is not limited herein.

Specifically, in the present embodiment, the conductive layer 11 serves as the first conductive layer 11, and the conductive layer 12 serves as the second conductive layer 12.
