It is all the slim sheet body of frame-type, influent stream plate 301, resonance plate 302, piezoelectric actuator 303, the first insulating trip 304, conductive sheet 305
And second insulating trip 306 sequentially stacked group constitute 30 overall structure of micropump.It needs to be formed between suspension board 303a and resonance plate 302
One cavity space 307.Cavity space 307 can be used between resonance plate 302 and the outline border 303b of piezoelectric actuator 303 and fill one
Material is formed, such as: conducting resinl, but not limited to this.So that certain depth can be maintained between resonance plate 302 and suspension board 303a
To form cavity space 307, and then gas can be guided and more quickly flowed, and because suspension board 303a and resonance plate 302 keep suitable
It is reduced when distance makes to be in contact with each other to interfere, promotes the generation of noise that can be lowered.It, can be by increasing piezoelectricity in other embodiments
The outline border 303b height of actuator 303 fills conduction between resonance plate 302 and the outline border 303b of piezoelectric actuator 303 to reduce
The thickness of glue expands with heat and contract with cold with hot pressing temperature and cooling temperature in this way, can avoid conducting resinl and influences forming rear chamber
The practical spacing in space 307, the hot pressing temperature and cooling temperature for reducing conducting resinl assemble 30 overall structure of micropump indirect
It influences, but not limited to this.In addition, the depth of cavity space 307 will affect the laser propagation effect of micropump 30, therefore one is maintained to fix
It is highly important that the cavity space 307 of depth, which provides stable efficiency of transmission for micropump 30,.
As shown in Figure 10 B, in other embodiments, suspension board 303a can be adopted makes it extend outwardly in a manner of stamping
One distance, the distance that extends outwardly can be adjusted by at least bracket 303c formed between suspension board 303a and outline border 303b
It is whole, so that both the surface of the protrusion 303f on suspension board 303a and the surface of outline border 303b is formed non-co-planar, is used in outer
Assembling for frame 303b is coated with a small amount of filling material on surface, such as: conducting resinl is bonded piezoelectric actuator 303 with hot pressing mode
In the fixed part 302c of resonance plate 302, so that piezoelectric actuator 303 is able to assemble combination with resonance plate 302.So directly
It adopts through by the suspension board 303a of piezoelectric actuator 303 with the stamping structural improvement to constitute cavity space 307, it is required

Constitute the micropump of a MEMS.
In embodiment of this case, micropump 30 makees flowing mode as shown in Figure 10 C to Figure 10 E, please referring initially to Figure 10 C, pressure
The piezoelectric element 303d of electric actuator 303 generates deformation drive suspension board 303a to far from influent stream plate after being applied driving voltage
301 direction displacement, the volume of cavity space 307 is promoted at this time, in foring negative pressure in cavity space 307, just draws confluence
Gas in chamber 301c enters in cavity space 307, while resonance plate 302 is influenced by resonance principle and synchronized to separate
The direction of influent stream plate 301 is displaced, the related volume for increasing confluence chamber 301c, and because the gas in confluence chamber 301c enters
The relationship of cavity space 307 causes to be similarly negative pressure state in confluence chamber 301c, and then passes through flow-in hole 301a and busbar connector
Slot 301b carrys out draw gas and enters in confluence chamber 301c.Referring again to Figure 10 D, piezoelectric element 303d drive suspension board 303a to
It is displaced close to the direction of influent stream plate 301, compression chamber space 307, likewise, resonance plate 302 with suspension board 303a due to resonating
It is displaced to the direction close to influent stream plate 301, the synchronous gas pushed in cavity space 307 passes through an at least gap 303e to unofficial biography
It is defeated, to achieve the effect that transmit gas.Finally please refer to Figure 10 E, when suspension board 303a homing, resonance plate 302 still because
Inertia and be displaced to the direction far from influent stream plate 301, compression chamber space 307 makes cavity space 307 by resonance plate 302 at this time
Interior gas is mobile to the direction of an at least gap 303e, and promotes the volume in confluence chamber 301c, and gas can be held
Continuous ground is converged at by flow-in hole 301a and busbar channel 301b in confluence chamber 301c.Through being repeated continuously above-mentioned figure
The actuation step of micropump 30 shown in 10C to Figure 10 E, enable micropump 30 make gas continuously from flow-in hole 301a enter into
Runner that flowing plate 301 and resonance plate 302 are constituted simultaneously generates barometric gradient, then is transmitted outward by an at least gap 303e, makes gas
Body flow at high speed reaches the actuation operation that micropump 30 transmits gas.
Figure 11 to Figure 12 C is please referred to, in embodiment of this case, gas actuator 224 (as shown in Figure 5A) and particle are caused
