The orientation or positional relationship of the instructions such as term "inner", "outside", "upper", "lower", "front", "rear" is position based on the figure pass
System, is merely for convenience of describing the present invention and simplifying the description, rather than the device or element of indication or suggestion meaning are necessary
It with specific orientation, is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition,
Term " first ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
As shown in Fig. 1 to 2, mixing piezoelectric pump includes the pump housing 1 and piezoelectric vibrator 2, and the pump housing 1 is provided with inner cavity 5, piezoelectric vibrator
2 are mounted in inner cavity 5.
Inlet 3 is arranged in 1 front end of the pump housing, and liquid outlet 4 is arranged in rear end.
Piezoelectric vibrator 2 includes the oscillator matrix of plate, and is mounted on the piezoelectric ceramics of oscillator matrix upper and lower surface.
By inverse piezoelectric effect, piezoelectric ceramics drives oscillator matrix to generate bending deformation, so that piezoelectric vibrator 2 is swung,
The fluid in inner cavity 5 is stirred, fluid is flowed.Fluid enters the pump housing 1 by inlet 3, then passes through liquid outlet by piezoelectric vibrator 2
4 pump out.
Inner cavity 5 is divided for the pump section 5.1 positioned at front side and the mixing unit 5.2 positioned at rear side.
Pump section 5.1 is divided by the partition 6 of setting for multiple pumping passage 5.1a being connected with mixing unit 5.2, each
Piezoelectric vibrator 2 is mounted in pumping passage 5.1a.
Inlet 3 be arranged it is multiple, each inlet 3 with corresponding pumping passage 5.1a be connected.
6 front end of partition is connected with 5 front inner wall of inner cavity, so that the front end of pumping passage 5.1a be made to close, only passes through feed liquor
It is connected outside mouth 3 and pump, will not be interfered with each other between pumping passage 5.1a, liquid is difficult to flow back, and can only pass through pumping passage 5.1a
Rear end is flowed into mixing unit 5.2.Interval is set between 5 rear side inner wall of 6 rear end of partition and inner cavity, thus in 5 rear portion shape of inner cavity
At mixing unit 5.2.
Plurality of liquid enters in corresponding pumping passage 5.1a, respectively by different inlets 3 in piezoelectric vibrator 2
Fluctuation under be flowed in mixing unit 5.2.The plurality of liquid mixing in mixing unit 5.2 is entered, is pumped out by liquid outlet 4.
