Detailed description of the invention
With reference to Fig. 1, a kind of elliposoidal bionic pump with the elastic pump housing of the present invention, is by outlet 1, Outlet check valves 2,
The elastic pump housing 3, inlet tube 4, inlet one-way valve 5, substrate 601, flexible piezoelectric fibrous composite 602 forms, wherein:
Flexible piezoelectric fibrous composite 602, under the effect of alternating voltage, its motion mode is laterally to be produced at material
Raw dilatation, this device needs left and right translation, for reaching this purpose, paste bottom flexible piezoelectric fibrous composite 602 by
The glass fibre epoxy that epoxy resin and glass fabric are made strengthens composite substrate 601, at glass fibre basal plate 601
Limit lower so that whole drive part produces cyclic bending deformation, flexible piezoelectric fibrous composite 602 and glass fibre
Substrate 601 collectively forms flexible piezoelectric driver 6.
The elastic pump housing 3, outlet 1 and inlet tube 5 made by elastic silica gel material, in an initial condition, the elastic pump housing 3
For elliposoidal.Outlet check valves 2 and inlet one-way valve 5 are PET material.The elastic pump housing about 3 both sides are respectively arranged with an aperture, use
Inlet one-way valve 5 is adhered to the inner side of elastic 3 times perforates of the pump housing by silicone rubber adhesive, is i.e. positioned at inside cavity, exports unidirectional
Valve 2 is adhered to the outside of perforate on the elastic pump housing 3, is i.e. positioned at containment portion.Outlet 1 and inlet tube 4 stick at elastic pump respectively
The relevant position of body about 3 both sides.
Glass fibre basal plate 601 in cross-shaped, i.e. its any two adjacent edge angle 90 °, glass fibre basal plate 601
Lower surface and the elastic pump housing 3 outer surface close adhesion, i.e. glass fibre basal plate 601 have one with the elliposoidal elasticity pump housing 3 surface
Fixed crooked radian.
It is positioned at the two panels flexible piezoelectric fibrous composite 602 outside glass fibre basal plate 601 plane of symmetry in decussation
Arrangement, flexible piezoelectric fibrous composite 602 has the crooked radian consistent with glass fibre basal plate 601 and and glass fibre
Substrate 601 close adhesion.
Alternating voltage is applied to described flexible piezoelectric fibrous composite 602, under the effect of alternating voltage, flexible piezoelectric
Fibrous composite 602 does the reciprocating motion shortened and extend.When two symmetric outer surface at glass fibre basal plate 601 are bonding
In decussation, the two panels flexible piezoelectric fibrous composite 602 of arrangement when extending simultaneously, due to glass fibre basal plate 601
Limit so that two flexible piezoelectric drivers 6 are produced flexural deformation further out by equilbrium position simultaneously, drive and glass fibers
The bonding elastic pump housing 3 of Wiki plate 601 moves out simultaneously, and the whole elastic pump housing 3 radical length shortens and cross-sectional area becomes
Greatly, the elastic pump housing 3 is become approximate spheres from spheroid, and pump chamber volume increases, and the outlet being positioned at the elastic pump housing 3 upper side external is unidirectional
Valve 2 closes, and the inlet one-way valve 5 being simultaneously positioned at the elastic pump housing 3 lower inner part is opened, and fluid from outside is via inlet tube 4 and beats
The inlet one-way valve 5 opened flows into inside the pump chamber of the elastic pump housing 3.
When flexible piezoelectric fibrous composite 602 is returned to poised state by elongation state, flexible piezoelectric driver 6
Crooked radian is gradually reduced until the state that restores balance, and the elastic pump housing 3 is returned to spheroid by approximate spheres.In the process,
Inlet one-way valve 5 is closed, and Outlet check valves 2 is opened, through Outlet check valves 2 and outlet in the fluid from pump chamber in the elastic pump housing 3
Pipe 1 flows out, until poised state.Now pump chamber internal and external pressure balance, inlet one-way valve 5 and Outlet check valves 2 are turned off.
When flexible piezoelectric fibrous composite 602 shortens, due to the restriction of glass fibre basal plate 601 so that two soft
Property piezoelectric actuator 6 simultaneously produced inside flexural deformation by equilbrium position, drive and elasticity that glass fibre basal plate 601 is bonding
The pump housing 3 simultaneously inward, the whole elastic pump housing 3 radical length is elongated and cross-sectional area diminishes, the elliposoidal elasticity pump housing 3 from
Visually see that relative original state can become flat, the pump chamber volume-diminished of the elastic pump housing 3, it is positioned at entering of the elastic pump housing 3 lower inner part
Mouth check valve 5 closes, and the Outlet check valves 2 being simultaneously positioned at the elastic pump housing 3 upper side external is opened, and fluid continues from the internal warp of pump chamber
Outlet check valves 2 and outlet 1 by opening flow out.
When flexible piezoelectric fibrous composite 602 is by when shortening recovering state to poised state, due to glass fibre basal plate
The restriction of 601, the crooked radian of two piezoelectric actuators 6 is gradually increased until the state that restores balance.In the process, entrance list
Opening to valve 5, Outlet check valves 2 is closed, and fluid is flowed into pump chamber by outside through inlet tube 4 and inlet one-way valve 5, until elastic pump
The pump chamber external and internal pressure of body 3 reaches balance, and now, inlet one-way valve 5 and Outlet check valves 2 are turned off.Move and so forth, real
The suction of existing fluid and discharge.
