Abstract

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.

Description

technical field [0001] The invention relates to a piezoelectric ceramic atomizing sheet, in particular to a 3D printing lead-free piezoelectric ceramic atomizing sheet, which belongs to the technical field of piezoelectric elements. Background technique [0002] Nebulizer is a simple low-power atomizing device, which is widely used in the field of medical spraying. With the improvement of human living standards, the demand for nebulizers in household fields such as humidification and aromatherapy is becoming more and more extensive. [0003] The piezoelectric atomizer is the core component of the atomizer. At present, the piezoelectric ceramics used in the piezoelectric atomizer are mainly lead zirconate titanate (PZT) ceramic materials. Because lead-containing materials are extremely harmful to the human body and the environment, for the sustainable development of humans and the environment, it is urgent to use lead-free piezoelectric materials to replace the existing lead-...
