Description
Technical Field
The invention relates to the field of application of piezoelectric ceramic resonators, in particular to a piezoelectric ceramic atomization sheet.
Background
The piezoelectric ceramic ultrasonic atomizer utilizes the inverse piezoelectric effect of a piezoelectric ceramic atomizing sheet, namely: when a voltage is applied to the surface of the piezoelectric ceramic, the piezoelectric ceramic generates a mechanical deformation effect. The piezoelectric ceramic ultrasonic atomizer utilizes the high-frequency resonance motion of the ceramic atomizing sheet to disperse liquid clusters into a large amount of liquid with tiny volume, thereby forming mist to be sprayed out. The atomizing sheet is a core component of the piezoelectric ceramic ultrasonic atomizer, and is essentially a piezoelectric ceramic resonator with high power.
Fig. 1 is a schematic diagram of the basic structure of a typical piezoceramic atomization sheet. As shown in fig. 1, the atomization sheet mainly comprises a piezoelectric substrate 1, a liquid driving electrode layer 2 and a non-liquid driving electrode layer 3 which are adhered to the upper surface and the lower surface of the piezoelectric substrate 1, and a liquid container 6 for atomization of an atomizer. Wherein, the liquid driving electrode layer 2 and the non-liquid driving electrode layer 3 are made of metal materials; the piezoelectric substrate 1 is a piezoelectric ceramic material, and when high-frequency electric signals are applied to the upper and lower surfaces of the piezoelectric substrate 1, the piezoelectric substrate 1 generates high-frequency acoustic signals (high-frequency vibration). The atomizing plate is installed at the bottom of the liquid container to be atomized 6 of the atomizer, and a certain amount of liquid to be atomized is contained in the liquid container to be atomized 66 of the atomizer. At this time, the liquid driving electrode layer 2 is in contact with the liquid, the non-liquid driving electrode layer 3 is not in contact with the liquid, a driving control circuit generates a driving voltage consistent with the resonant frequency of the piezoelectric substrate 1, and when the driving control circuit is conducted, the atomization plate generates oscillation energy. The oscillation energy is transmitted in the liquid along the direction vertical to the surface of the atomizing sheet, when the depth of the liquid is proper, the liquid surface on the energy transmission shaft is intensively raised to form a liquid column 5, and the front end of the liquid column is dispersed in the air due to cavitation to form the effect of fog.
However, in the atomizing sheet with the above structure, the oscillation energy transmitted to the liquid around the liquid driving electrode layer 2 is relatively small, so that the liquid column atomizing efficiency is reduced; in addition, because the oscillation energy gathered around the non-liquid driving electrode layer 3 is too much, most of the energy is converted into heat energy to be spread outwards, so that the atomizing plate generates heat seriously, and the service life of the atomizing plate is influenced.

The piezoelectric substrate 1 of the piezoelectric ceramic atomizing sheet provided in the first embodiment of the present invention is a cylindrical piezoelectric ceramic material, but the piezoelectric substrate 1 provided in the present invention is not limited to a cylindrical structure, and may be other structures such as a rectangular parallelepiped. The upper and lower surfaces of the piezoelectric substrate 1 are provided with round surface silver electrodes: the liquid driving electrode layer 2 and the non-liquid driving electrode layer 3, but the surface electrode layer provided by the present invention is not limited to this structure, and the liquid driving electrode layer 2 and the non-liquid driving electrode layer 3 may be in other shapes such as a square shape, or may be made of other metal materials such as nickel and copper. The area of the non-liquid-driving electrode layer 3 is smaller than or equal to the area of the piezoelectric substrate 1, and the area of the liquid-driving electrode layer 1 is smaller than the area of the non-liquid-driving electrode layer 2. The piezoelectric substrate 1, the liquid-driving electrode layer 2 and the non-liquid-driving electrode layer 3 are coaxial, and the forward projection of the liquid-driving electrode layer 2 falls within the non-liquid-driving electrode layer 3.

However, the present invention is not limited to this structure, and the first wire 21 and the second wire 31 may be used to be directly electrically connected to the liquid driving electrode layer 2 and the non-liquid driving electrode layer 3; it is also possible to provide the first pads 22 and the second pads 32 on the upper and lower surfaces of the piezoelectric substrate 1, respectively, so that the first pads 22 and the second pads 32 are electrically connected to the liquid driving electrode layer 2 and the non-liquid driving electrode layer 3, respectively.
When the piezoelectric ceramic atomization sheet provided by the first embodiment of the invention is used, the atomization sheet is placed at the bottom of a container containing liquid to be atomized of a piezoelectric ceramic ultrasonic atomizer, the liquid driving electrode layer 2 is positioned on one side of the bottom, which faces the inside of the container, and the non-liquid driving electrode layer 3 is positioned on one side of the bottom, which faces the outside of the container, so that the liquid driving electrode layer 2 is in full contact with the liquid in the container containing the liquid to be atomized, and the non-liquid driving electrode layer 3 is in liquid contact. In order to protect the sealing performance and the service life of the atomizing plate, a waterproof silica gel ring 4 is required to be sleeved on the surface of the atomizing plate.

In order to prevent the liquid from corroding the piezoelectric ceramic atomization plate, the outer surface of the liquid driving electrode layer 2 is coated with a protective glaze layer 25, and the edge of the piezoelectric substrate 1 is sleeved with a silica gel ring 4. The liquid driving electrode layer 2 and the non-liquid driving electrode layer 3 are respectively electrically connected with a driving control circuit, the driving control circuit generates driving voltage consistent with the resonant frequency of the piezoelectric substrate 1, and the driving voltage is applied to the upper surface and the lower surface of the piezoelectric substrate 1, so that the piezoelectric ceramic atomization generates high-frequency resonance. The oscillation energy transmitted to the liquid around the liquid driving electrode layer 2 is more, and the oscillation energy transmitted to the non-liquid driving electrode layer 3 is less, so that the atomization efficiency of the piezoelectric ceramic atomization sheet is improved, and the problem of self heating of the atomization sheet is relieved.
