Abstract
The utility model discloses a kind of two-sided piezoelectric pump potsherd.Formed including the connection combination of base material, piezoelectric ceramics, silver layer, insulating protective layer and lead.Silver layer is distributed on two faces of cylinder of single layer piezoelectric ceramics, and two sides is covered with the piezoelectric ceramic piece of silver layer and is distributed on two faces of cylinder of base material with the plane of symmetry of base material.Two-sided piezoelectric pump potsherd can make the input power of piezoelectric pump improve 13 times than the piezoelectric pump that one side piezoelectric pump potsherd is made, thus greatly improve the flow and pressure parameter of piezoelectric pump, also just expand the range of application of piezoelectric pump.
Description
Technical field
The present invention relates to micropump, more particularly, it relates to a kind of inverse piezoelectric effect with piezoelectric ceramic piece is energy converting means
The piezoelectric pump put.
Background technology
Piezoelectric pump is a kind of novel fluid driver.It does not need additional drives motor, but utilizes the inverse of piezoelectric ceramics
Piezo-electric effect is deformed piezoelectric vibrator (piezoelectric ceramic piece), then produces the volume change of pump chamber to realize that fluid is exported by deformation
Or produce fluctuation to transmit liquid using piezoelectric vibrator, due to piezoelectric pump by the driving source part of conventional pump, running part and
The pump housing three be integrated, realize simple structure, small volume, lightweight, the low, noise that consumes energy it is small, without electromagnetic interference, and can basis
Applied voltage or FREQUENCY CONTROL output flow, can be widely applied to small type mobile devices, CPU and display card, game machine control panel,
Notebook computer, blade server, barrier-layer cell, LED, household electrical appliances, medicine equipment, petrochemical equipment, biomedicine, battery
The product of the conveying of the fluids such as fluid injection, automobile and avionic device, delicate metering fluid injection and Water Cooling Technology scheme is supporting.
Piezoelectric pump is made up of piezoelectric vibrator (piezoelectric ceramic piece), pump valve and the pump housing.Its operation principle is；When piezoelectric vibrator two
When end applies AC power U, piezoelectric vibrator radial expansion under electric field action, inside produces stretching or compression stress, so that
Piezoelectric vibrator flexural deformation.When piezoelectric vibrator is positive to be bent, pump chamber increase, cavity fluid pressure reduces, fluid inlet
Pump valve is opened, and liquid enters pump chamber；When piezoelectric vibrator is to back-flexing, pump chamber reduces, cavity fluid pressure increase, stream
Body import pump valve is closed, and pump chamber liquid is extruded discharge, forms gentle continuously directed flow.
Piezoelectric pump is a kind of new pump, and existing procucts want real penetration and promotion and benefit the people's livelihood to also have not on the market now
Few problem needs to solve, dilatation, the performance boost of pump and manufacturing process improvement of piezoelectric pump piezoelectric ceramic piece input power etc.
Many aspects have the space that can be improved and be lifted.Piezoelectric pump generally does motive drive source using one side piezoelectric ceramic piece, single
Face piezoelectric ceramic piece input power is little, from for the principle of the conservation of energy, the piezoelectric pump output that one side piezoelectric ceramic piece is made
Flow and pressure be just greatly limited.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of new piezoelectric pump potsherd --- two-sided piezoelectricity
Pump potsherd, the input power of the potsherd will be the twice or several times of one side piezoelectric ceramic piece.It can efficiently solve list
The piezoelectricity pump discharge and pressure index that face piezoelectric ceramic piece is made are difficult to the problem for being lifted.
The technical solution of the utility model is as follows：By the piezoelectric ceramics and silver layer of one side piezoelectric ceramics plate substrate side another
Side replicates to form two-sided piezoelectric ceramic piece, and in two-sided piezoelectric ceramic piece suitable position, punching is easy to outermost two with lead
The silver layer on side is connected in parallel.The shunt leads of silver layer is not justified from the surrounding of piezoelectric ceramic piece through unfavorable piezoelectric ceramic piece is avoided
The series of problems such as positioning and sealing is installed in week.Safety problem is caused in order to prevent silver layer from contacting the conducting medium such as water, we can be with
Insulating protective layer is installed additional in the one side of the conductive working media of contact.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is illustrated in greater detail.
It is the practical application of the utility model two-sided piezoelectric pump potsherd of pressure referring to accompanying drawing 1-5.The embodiment is by base material
(1), the piezoelectric ceramics (2) of base material (1) both sides, the silver layer (4) of piezoelectric ceramics (2) both sides, insulating protective layer (3) and two leads
(5) constitute.Two sides silver layer (4) wire through a piece lead (5) of formation in parallel after through hole A on the outside of two piezoelectric ceramics (2),
A is the through hole through all silver layers (4), piezoelectric ceramics (2) and base material (1).The hole B of Fig. 4 is another form of lead perforation,
The hole is not passed through silver layer (4) and piezoelectric ceramics (2) just through the peripheral edge of base material (1) circumference.Working media such as pump is sky
Gas, insulating protective layer (3) can omit without.Piezoelectric pump potsherd, most important of which electrical parameter is its capacitance, piezoelectricity
Potsherd capacitance is directly proportional to the input power of piezoelectric pump, and we can accomplish at the capacitance of this two-sided piezoelectric pump potsherd
The twice of one side piezoelectric pump potsherd or four times, that is, the input power of piezoelectric pump can improve 1-3 times, thus greatly carry
The flow and pressure parameter of piezoelectric pump have been risen, the range of application of piezoelectric pump has also just been expanded.
