Description
Technical field
The present invention relates to micropump, more particularly, it relates to the piezoelectric pump that a kind of inverse piezoelectric effect with piezoelectric ceramic piece is as energy conversion device.
Background technology
Piezoelectric pump is a kind of novel fluid driver.nullIt need not additional drives motor，But utilize the inverse piezoelectric effect of piezoelectric ceramics to make piezoelectric vibrator (piezoelectric ceramic piece) be deformed，Realized fluid output by the volume change of deformation generation pump chamber again or utilize piezoelectric vibrator to produce fluctuation to transmit liquid，Owing to piezoelectric pump is by the driving source part of conventional pump、Running part and pump housing three are integrated，Realize simple in construction、Volume is little、Lightweight、Consume energy low、Noise is low、Without electromagnetic interference，And can be according to applying voltage or FREQUENCY CONTROL output flow，Can be widely applied to small type mobile devices、CPU and display card、Game machine panel、Notebook computer、Blade server、Barrier-layer cell、LED、Household electrical appliances、Medical apparatus and instruments、Petrochemical equipment、Biomedical、Battery liquid-filling、The fluid such as automobile and avionic device carries、The product of delicate metering fluid injection and Water Cooling Technology scheme is supporting.
Piezoelectric pump is made up of piezoelectric vibrator, pump valve and the pump housing.Its operation principle is；When piezoelectric vibrator two ends apply alternating current power supply U, piezoelectric vibrator is radial expansion under electric field action, and internal generation stretches or compression stress, so that piezoelectric vibrator flexural deformation.When piezoelectric vibrator forward bends, pump chamber increases, and cavity fluid pressure reduces, and fluid inlet pump valve is opened, and liquid enters pump chamber；When piezoelectric vibrator is to back-flexing, pump chamber reduces, and cavity fluid pressure increases, and fluid inlet pump valve cuts out, and pump chamber liquid is extruded discharge, forms mild continuously directed flow.
Piezoelectric pump is a kind of new pump; now existing procucts want real penetration and promotion also have many problems to need to solve the most on the market, and the protection of piezoelectric pump piezoelectric pump potsherd and localization method, pump performance promote and many aspects such as manufacturing process improvement have the space can improved and promote.
Summary of the invention
The technical problem to be solved is to provide a kind of piezoelectric pump potsherd localization method, and the method promotes the energy conversion efficiency of piezoelectric ceramic piece, prevents piezoelectric ceramic piece silver layer from getting wet piezoelectric ceramic piece fragmentation when burning couple ultrasonic with piezoelectric pump shell.
Technical scheme is as follows: at the piezoelectric ceramic piece largest circumference of piezoelectric pump, upper and lower surface flexible material supports location, at largest circumference, cylinder and middle casing matching surface are tight fit location, upper-lower casing and vavle shelf compress the sealing member that flexible material is made, limit piezoelectric ceramic piece to move linearly in the axial direction, leave gap between upper and lower surface and vavle shelf and upper-lower casing at piezoelectric ceramic piece circumference simultaneously, this gap ensures that piezoelectric ceramic piece can freely up and down swing for fulcrum at largest circumference, the localization method following points benefit of this piezoelectric ceramic piece: one, piezoelectric ceramic piece freely up and down swings for fulcrum at circumference, substantially the radial expansion of piezoelectric ceramic piece is deformed and be converted into axial amplitude, thus be effectively improved electric energy and be converted into the efficiency of mechanical energy；Two, as complete machine couples fastening, to change screw attachment be ultrasonic bonding, because of upper-lower casing and vavle shelf with piezoelectric ceramic piece circumferential surface without rigid attachment, directly the energy of ultrasound wave will not be delivered to potsherd during ultra-sonic welded, prevent from destroying piezoelectric ceramic piece during ultrasonic bonding；Most be afraid of to get wet during the painting silver face energising of three, piezoelectric ceramic piece, and water pump is the device with water as working media, thus, the waterproofing protection being coated with silver face of piezoelectric ceramic piece is the most critically important.The flexible material part of piezoelectric ceramic piece circumference upper and lower surface both for support part be also obturator, be equivalent to do dual waterproof to the painting silver face of piezoelectric ceramic piece.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be described in more detail.
See accompanying drawing 1-3, for the piezoelectric pump potsherd localization method of the present invention actual application in double potsherd piezoelectric pumps.This embodiment is by upper shell (1), lower house (9), middle casing (2), upper piezoelectric pump potsherd (3), lower piezoelectric pump potsherd (8), upper valve block (5), lower disc (6), sealing ring (10) 4, upper vavle shelf (4) and lower vavle shelf (7) composition.See accompanying drawing 3 and accompanying drawing 4 again, sealing ring (10) is respectively placed in piezoelectric pump potsherd (3) or 103 of lower piezoelectric pump potsherd (8) and 105, sealing ring (10) is pressed in upper piezoelectric pump potsherd (3) or 103 of lower piezoelectric pump potsherd (8) and 105 after ultrasonic bonding by upper shell (1) and lower house (9), dual-seal is by the painting silver face 102 of upper piezoelectric pump potsherd (3) or lower piezoelectric pump potsherd (8) and 105 isolation being positioned at upper piezoelectric pump potsherd (3) or lower piezoelectric pump potsherd, the inflow piezoelectric pump potsherd 102 of the liquid after piezoelectric pump potsherd 105 can be effectively prevented and be coated with silver face, thus prevent piezoelectric pump potsherd to be energized after getting wet because of 102 painting silver faces and burn；Upper shell (1) and lower house (9) are after ultrasonic bonding, upper shell (1) and lower house (9) leave gap delta with piezoelectric pump potsherd 103 face, upper vavle shelf (4) and lower vavle shelf (7) also leave gap delta with piezoelectric pump potsherd 105 face, because the sealing ring that this gap delta allows upper and lower vavle shelf and upper-lower casing and piezoelectric pump potsherd make without the only flexible material that is rigidly connected supports, thus when greatly attenuating upper-lower casing ultrasonic bonding, the energy of piezoelectric pump potsherd is transmitted, protection piezoelectric pump potsherd is not because of dither and fragmentation during ultrasonic bonding；Piezoelectric pump potsherd 104 and middle casing (2) inner circle tight fit connection, limit the deformation of piezoelectric pump potsherd radial expansion, because the gap delta in accompanying drawing 3 and flexible material support, piezoelectric pump potsherd axial vibration is interference-free, and the inverse piezoelectric effect of piezoelectric pump potsherd obtains maximized performance.In accompanying drawing 4,101 is power supply lead wire.As a example by the piezoelectric pump potsherd localization method of the present invention actual application in double potsherd piezoelectric pumps, but being not limited only in double potsherd piezoelectric pumps application, single other occasion such as potsherd or many potsherds piezoelectric pump is equally applicable.
