Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments: this embodiment is only a basic embodiment of the present invention, rather than all embodiments.

[0037] Such as figure 1 As shown, a radially porous 3D printed lead-free piezoelectric ceramic atomizer, the lead-free piezoelectric ceramic atomizer is made of potassium sodium niobate-based lead-free piezoelectric ceramic.

[0038] The piezoelectric ceramic sheet is circular, with 4 radial grooves, such as figure 2 As shown, the outer diameter of the ring is 60mm and the inner diameter is 52mm.

[0039] The diameter of the through hole of the groove of the piezoelectric ceramic sheet is 10mm, and the diameter of the groove is 16mm.

[0040] The metal sheet is circular, such as image 3 As shown, the diameter is 16mm.

[0041] The thickness of the metal sheet is 0.2mm.

[0042] The atomization hole structure of the metal sheet is c...

Abstract

The invention provides a radial porous fogging 3D printing leadless piezoelectric ceramic atomizing piece which comprises a 3D printing leadless piezoelectric ceramic piece and sheet metal with an atomizing hole; electrode layers are attached to the internal and external diameter surfaces of the 3D printing leadless piezoelectric ceramic piece; and the sheet metal is fixed in a radial groove of the leadless piezoelectric ceramic piece through a binder. According to the invention, a 3D printer is adopted to form the leadless piezoelectric ceramic piece, the sheet metal is fixed in the radial groove of the leadless piezoelectric ceramic piece through the binder, and a plurality of fogging holes are formed in the radial direction of the structure to effectively increase the fogging quantity and fogging range; and in addition, the sheet meal is fixed in the groove of the leadless piezoelectric ceramic piece, so that the weight of the sheet metal can be reduced and the conversion efficiencyof the kinetic energy is improved.

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 electronic components. Background technique [0002] Atomizers are currently widely used in the household field. However, the direction of fog output from current atomizers is basically upward, which is difficult to adjust, and the range of fog output is relatively narrow. [0003] The piezoelectric atomizer is the core component of the atomizer. Currently, the materials used in the piezoelectric atomizer on the market are mainly lead zirconate titanate (PZT) ceramic materials. Because lead-containing materials are toxic and harmful, which are extremely harmful to the ecological environment and human health, it has become a general trend to develop lead-free piezoelectric materials to replace lead-containing piezoelectric materials. [0004] Traditional c...
