Embodiment Construction

[0019] The structure and working principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] figure 1 :1-upper pump body 2-lower pump body 3-upper piezoelectric vibrator 4-lower piezoelectric vibrator 5-compression spring 6-conical inlet 7-conical outlet 8-sealing ring

[0021] Such as figure 1 As shown, the micropump consists of an upper pump body, a lower pump body, an upper piezoelectric vibrator, a lower piezoelectric vibrator, a compression spring, a tapered inlet, a tapered outlet, and a sealing ring. Four bolt holes are evenly distributed on the upper pump body, and the tapered outlet is located on the right side of the upper pump body; four bolt holes are symmetrically distributed on the lower pump body and the upper pump body; sealing grooves are opened on both the upper and lower pump bodies; At the same time, the upper pump body, the seal, and the lower pump body are stacked together in turn, and the...

Abstract

A valveless piezoelectric pump for a double-cantilever oscillator comprises an upper pump body, a lower pump body, an upper piezoelectric oscillator body, a lower piezoelectric oscillator body, a pressing spring, a conical inlet, a conical outlet and a sealing ring. The valveless piezoelectric pump is characterized in that the left end of the upper piezoelectric oscillator body is integrally connected with the left end of the lower piezoelectric oscillator body to be in a v shape, the right end of the upper piezoelectric oscillator body is fixed to the upper pump body, and the right end of the lower piezoelectric oscillator body is pressed by the pressing spring. When the piezoelectric pump is in a non-work state, the lower piezoelectric oscillator body is completely in contact with the bearing plane of the lower pump body.

Description

technical field [0001] The invention belongs to the field of fluid machinery, in particular to a double cantilever vibrator valveless piezoelectric pump. Background technique [0002] Piezoelectric micropumps have many advantages such as simple structure, low energy consumption, small size, and light weight. With the deepening of research on piezoelectric micropumps, piezoelectric micropumps have been widely used in various fields in recent years. [0003] The Chinese invention patent application with the application patent number 201310292377.4 discloses a piezoelectric micro-diaphragm pump. The size of the gap between the diaphragm and the mounting support plane of the bottom plate is smaller than or equal to the thickness of the vibrating part of the cantilever of the piezoelectric vibrator, so that the diaphragm contacts or presses The vibrating part of the cantilever that tightens the piezoelectric vibrator, since the diaphragm and the piezoelectric vibrator are in plan...
