Abstract

The invention discloses a vibrating piezoelectric spray head system. The vibrating piezoelectric spray head system comprises a liquid storage cavity. A liquid supply connector is arranged above the liquid storage cavity. A liquid outlet is formed in the bottom of the liquid storage cavity. A piezoelectric ceramic vibrating mechanism used for vibrating so as to spray fluid is arranged at the bottom of the liquid storage cavity. The piezoelectric ceramic vibrating mechanism comprises an annular piezoelectric ceramic vibrating piece and a metal piece, wherein the annular piezoelectric ceramic vibrating piece and the metal piece are bonded together, convex conical holes communicating with the liquid outlet are formed in the annular piezoelectric ceramic vibrating piece and the metal piece, and a vibrating signal of the piezoelectric ceramic vibrating mechanism is guided in through an electrode on one side of the annular piezoelectric ceramic vibrating piece and an electrode on one side of the metal piece. Compared with the prior art, the vibrating piezoelectric spray head system is large in vibrating amplitude, and the problems that an existing printer spray head is prone to being blocked due to the fact that the fluid viscosity is large and is scrapped when severely blocked can be effectively solved.

Description

technical field [0001] The invention relates to a vibrating piezoelectric nozzle system, which belongs to the technical field of 3D printing. Background technique [0002] Additive manufacturing (3D printing) technology has spawned a large number of new production methods and changed the manufacturing process of traditional products. In particular, the traditional design, mold opening, pouring and other processes are no longer satisfactory to people's expectations for products. The traditional manufacturing process has high energy consumption, long cycle time, serious pollution and other disadvantages. Moreover, traditional manufacturing methods for complex devices cannot be satisfied. Coupled with the improvement of people's living standards, personalized customized products will also be the general trend. [0003] 3D printing abroad is in full swing. From the biological fields such as tissue culture to the living fields such as food printing and clothing printing, and th...
