3D printing lead-free piezoelectric ceramic atomization sheet
The invention provides a 3D printing lead-free piezoelectric ceramic atomization piece which comprises a 3D printing lead-free piezoelectric ceramic piece with electrode layers attached to the upper surface and the lower surface and a metal piece with atomization holes, and the metal piece is tightly attached to the interior of a specially-designed structure of the lead-free piezoelectric ceramicpiece through an adhesive. According to the invention, a 3D printing technology is adopted, the lead-free piezoelectric ceramic piece with a complex structure, high dimensional precision and excellentpiezoelectric property is obtained. The groove structure of the ceramic chip is utilized, the metal sheet is tightly attached to the lead-free piezoelectric ceramic sheet on the bonding surface and in the radial direction; the weight of the metal sheet is reduced, the energy required for the piezoelectric ceramic sheet to drive the metal sheet to vibrate is reduced, meanwhile, the ceramic sheet and the metal sheet are tightly combined, the transmission efficiency of kinetic energy is further improved, and the fog outlet amount is increased.
本发明提供的3D打印无铅压电陶瓷雾化片包括上下表面附着有电极层的3D打印无铅压电陶瓷片，和具有雾化孔的金属片，所述金属片通过粘结剂紧贴在无铅压电陶瓷片的特定设计的结构内。本发明通过3D打印技术，获得结构复杂，尺寸精度高和压电性能优异的无铅压电陶瓷片，利用陶瓷片的凹槽结构，使得金属片在粘结面和径向均与无铅压电陶瓷片紧贴在一起，该结构减少了金属片的重量，使得压电陶瓷片带动金属片振动所需能量减少，同时陶瓷片和金属片的紧密结合，进一步提高了动能的传递效率，提高了出雾量。
