Piece 222 at movable part 222a with inlet plate 221 thereon with that after piezoelectric actuator 223 sequentially corresponding assembling, can be collectively formed
The chamber of one confluence gas, and a first chamber 220 is more formed between resonance plate 222 and piezoelectric actuator 223, it is configured to temporarily store
Gas, and first chamber 220 be through resonance plate 222 hollow bore 2220 and at the central recess 221c of inlet plate 221
Chamber be connected, and the both sides of first chamber 220 then by the gap 2235 between the stent 2233 of piezoelectric actuator 223 and with
The air guide end opening 201 being arranged under it is connected.
Fig. 8 A to 8E are the flowage structure figure of the gas pump start shown in Fig. 5 A and 5B.Fig. 7, Fig. 8 A to Fig. 8 E are referred to,
The start process description of the gas pump of this case is as follows.When gas pump 22 carry out start when, piezoelectric actuator 223 by voltage actuation and
It is fulcrum with stent 2233, carries out the reciprocating vibration of vertical direction.As shown in Figure 8 A, when piezoelectric actuator 223 is caused by voltage
It is dynamic and when vibrating downwards, be when piezoelectric actuator 223 vibrate, to be total to since resonance plate 222 is for light, thin laminated structure
Shake piece 222 also can with resonance and carry out vertical reciprocating vibration, be the part that resonance plate 222 corresponds to central recess 221c
Also can with bending vibration deformation, i.e. the part of correspondence central recess 221c is the movable part 222a for resonance plate 222, be with
When piezoelectric actuator 223 is bent downwardly vibration, the movable part 222a of the correspondence central recess of resonance plate 222 221c can be because of gas at this time
The drive brought into and pushed and piezoelectric actuator 223 vibrates of body, and as piezoelectric actuator 223 is bent downwardly vibration shape
Become, then gas is entered by at least air admission hole 221a on inlet plate 221, and converges round 221b through at least one to be pooled to
Center central recess 221c at, then via the hollow bore 2220 being correspondingly arranged on resonance plate 222 with central recess 221c to
Under flow into first chamber 220.Thereafter, due to being driven by 223 vibration of piezoelectric actuator, resonance plate 222 also can be total to
Shake and carry out vertical reciprocating vibration, as shown in Figure 8 B, at this time the movable part 222a of resonance plate 222 also with downward vibration,
And attach contact at piezoelectric actuator 223 suspension board 2231 protrusion 2231a on, make the protrusion 2231a of suspension board 2231 with
The spacing of confluence chamber between the fixed part 222b of outer 222 both sides of region and resonance plate will not become smaller, and by this resonance
The deformation of piece 222 to compress the volume of first chamber 220, and is closed 220 middle flow space of first chamber, is promoted in it
Gas is pushed to be flowed to both sides, and then passes through stream downwards by the gap 2235 between the stent 2233 of piezoelectric actuator 223
It is dynamic.Afterwards, as shown in Figure 8 C, the movable part 222a of resonance plate 222 is bent upwards vibration deformation, and returns back to initial position, and
Piezoelectric actuator 223 is driven by voltage to vibrate upwards, the so similary volume for squeezing first chamber 220, only at this time due to pressure
Electric actuator 223 is upward lifting, so that the gas in first chamber 220 can be flowed towards both sides, and then gas is driven to hold
Continuously enter from at least air admission hole 221a on inlet plate 221, then flow into the chamber that central recess 221c is formed.It
Afterwards, as in fig. 8d, which is resonated upwards by the vibration of 223 upward lifting of piezoelectric actuator, at this time resonance plate
222 movable part 222a also with upward vibration, and then mitigation of gases is constantly from at least air admission hole on inlet plate 221
221a enters, then flows into the chamber that central recess 221c is formed.Finally, as illustrated in fig. 8e, the movable part of resonance plate 222
222a also returns back to initial position.Thus embodiment aspect understands that, when resonance plate 222 carries out vertical reciprocating vibration, being can
By its gap h between piezoelectric actuator 223 to increase the maximum range of its vertical displacement, in other words, in two structure
Between set gap h that can make resonance plate 222 that can generate upper and lower displacement by a larger margin when resonance.Therefore through this gas pump
Barometric gradient is generated in 22 runner design, makes gas flow at high rates, and through runner into the resistance difference of outgoing direction, by gas
Outlet side is transmitted to by suction side, to complete gas conveying operation, even if in a state that outlet side has air pressure, still has the ability to hold
It is continuous to push air into water conservancy diversion chamber 200, and mute effect is can reach, 22 start of gas pump of Fig. 8 A to 8E is so repeated, i.e.,
Gas pump 22 can be made to generate the gas transport of an ecto-entad.
From the above, 22 start is pumped through above-mentioned gas, introduces gas into the water conservancy diversion chamber 200 of water conservancy diversion carrier 20, and
