Technical field
The present invention relates to a kind of Valveless piezoelectric pump, belong to field of fluid machinery.
Background technology
Valveless piezoelectric pump is simple in structure, machinery-free driving-chain, and reliability is high, and electromechanical conversion efficiency is high, easilyMicrominaturization, in health care, Aero-Space, have a wide range of applications in MEMS.
Summary of the invention
Fig. 1 is the structure chart of Valveless piezoelectric pump of the present invention. Conflict internally and flow pipe Valveless piezoelectric pump, it is characterized in that:The face of two circular piezoelectric vibrator 2 identical polars is arranged on the pump housing 3 relatively, two circular piezoelectric vibrators 2Between cavity be pump chamber 1, the pump housing 3 is connected to and is conflicted internally on stream pipe 5 by the through hole 4 of side;
The stream pipe 5 of conflicting internally is made up of the curved surface 8 in circular section pipe 7 and circular section pipe 7; Curved surface 8 cuts with circleThe space that facial canal 7 surrounds forms bent bucket 9; Curved surface 8 is involute surface shape; Curved surface 8 has been crossed the stream pipe 5 of conflicting internallyAxis 13; Bent bucket 9 is evenly staggered in axis 13 both sides of the stream pipe 5 of conflicting internally; The stream pipe 5 of conflicting internally has3 stream sockets, wherein the first gateway 10 and the second gateway 11 connect with extraneous pipeline, and the 3rdGateway 12 connects with the through hole 4 on the pump housing 3; Wherein the first gateway 10 and the second gateway 11 areThe gateway up and down of circular section pipe 7, the side at 7 middle parts is managed in the 3rd 12 circular section, gateway.
The operation principle of the internal conflict stream pipe Valveless piezoelectric pump that the present invention proposes is described below:
Two circular piezoelectric vibrators 2 are bonded in respectively two of end face of the pump housing 3 with the identical one side of polarityOn counterbore 16; The stream pipe 5 of conflicting internally is arranged on the through hole 4 of the pump housing 3 sides; Conflict internally stream pipe 5 by circular sectionCurved surface 8 in pipe 7 and circular section pipe 7 forms; Curved surface 8 forms bent with the space that circular section pipe 7 surroundsBucket 9; Curved surface 8 is involute surface shape; Curved surface 8 has been crossed the axis 13 of the stream pipe 5 of conflicting internally; Bent bucket 9 is interiorAxis 13 both sides of bucket stream pipe 5 are evenly staggered; The stream pipe 5 of conflicting internally has 3 stream sockets, whereinThe first gateway 10 and the second gateway 11 connect with extraneous pipeline, on the 3rd gateway 12 and the pump housing 3Through hole 4 connect; The side at 7 middle parts is managed in the 3rd 12 circular section, gateway.
The present invention uses the stream pipe 5 of conflicting internally to realize the one-way flow of fluid, has simplified the knot of conventional piezoelectric pumpStructure, this invention is applied in suspension in pharmacy, medical field, emulsion and containing the medicament of microparticleThe aspects such as preparation, conveying, injection, can form new technique, increase substantially production efficiency and yield rate.In addition, this invention also has potential use widely in other relevant Fluid Transport fields.

Detailed description of the invention
The specific embodiment of the invention is as Fig. 1-Fig. 5. Piezoelectric vibrator diameter 30mm, the stream bore 6mm that conflicts internally,Bent bucket involute base circle diameter (BCD) 3mm, operating voltage 220V, frequency 50Hz, taking water as working media, flowReach 2100mg/s.
In the time of piezoelectric pump incoming transport power supply, inhaling when journey, two piezoelectric vibrators 2 are at one of alternating currentIn half period, respectively to pump chamber 1 outside curve, pump chamber 1 internal pressure declines, and fluid is from the stream pipe 5 of conflicting internallyThe first gateway 10 and the second gateway 11 flow into, and through the 3rd gateway 12, through hole 4 inflow pumpsChamber 1; Press direction when alternating current changes, while entering the next half period, piezoelectric pump enters scheduling stage, twoIndividual piezoelectric vibrator 2 is respectively to pump chamber 1 inside bend, and pump chamber 1 volume declines, and pressure raises, pump chamber 1Interior fluid via through holes 4 and the 3rd gateway 12 flow into the stream pipe 5 of conflicting internally, and flow out the first gateway 10 HesThe second gateway 11; Due to the effect of bent bucket 9 in the stream pipe 5 of conflicting internally, fluid flows to from the first gateway 10The flow resistance of the second gateway 11 directions is less than and flows to the first gateway 10 directions from the second gateway 11Flow resistance; So, in scheduling, flow out the inhaling the fluid ratio being flowed into by the first gateway 10 in journeyThe fluid of one gateway 10 is many, in like manner, inhales the stream that is flowed into the stream pipe 5 of conflicting internally in journey by the second gateway 11Body, than the less fluid that flows out the second gateway 11 in scheduling, has therefore produced fluid and has gone out from first in macroscopic viewEntrance 10 flows into, the net flow flowing out from the second gateway 11.
