Technological scheme: in order to solve above-mentioned technical problem; The Archimedes spiral stream pipe Valveless piezoelectric pump of the utility model; Comprise the pump housing formed by lower cover and loam cake, be arranged on the pump chamber between lower cover and the loam cake; And be contained in the piezoelectric vibrator in the pump chamber, and also comprising first Archimedes spiral stream pipe and first connectivity slot that are arranged between lower cover and the loam cake, described Archimedes spiral flows Guan Yiduan and is connected with fluid inlet on being arranged on the pump housing; The other end is connected with pump chamber; One end of first connectivity slot is connected with pump chamber, and the other end is connected with fluid output, and promptly fluid inlet, first Archimedes spiral stream pipe, pump chamber, first connectivity slot and fluid output form the circulation passage of fluid.
Described first Archimedes spiral stream pipe can directly be connected with pump chamber, also can be connected with pump chamber through second connectivity slot that plays transitional function, and second connectivity slot plays the effect that reduces flow resistance.
One second Archimedes spiral stream pipe also can be set between first connectivity slot and the fluid output; Usually, described first Archimedes spiral stream pipe is for being the helical flow pipe that center and starting point counterclockwise are provided with the fluid inlet, and terminal point is tie point that links to each other with pump chamber or the tie point that links to each other with second connectivity slot; Described second Archimedes spiral stream pipe is for being the helical flow pipe that center and starting point clockwise direction are provided with the fluid output, and its terminal point is the tie point that links to each other with first connectivity slot.
Described Archimedes spiral stream pipe is for being etched in down the spiral form conduit whole in the same plane that covers; The profile line of Archimedes spiral stream pipe of the present invention is an Archimedes spiral; Also claim archimedes curve or constant velocity spiral, in works " opinion helical ", provided definition by Archimedes at first.As shown in Figure 2, when 1 P along moving ray OP with etc. speed when moving, this ray again with constant angular velocity around an O rotation, the track of some P is called " Archimedes spiral ".Its polar equation is: r=a θ, and the distance of every arm of this helical is equal to 2 π a forever, and wherein, r is a radius in the formula, and a is a constant, and θ is a polar angle.

In the pump housing He outside the pump housing, make things convenient for flows for the ease of fluid, fluid inlet is connected with extraneous through first fluid stream pipe, and fluid output is connected with extraneous through second fluid flow tubes.
During the Archimedes spiral of present technique scheme stream pipe Valveless piezoelectric pump work, piezoelectric ceramic and tinsel as the two poles of the earth, when the piezoelectric vibrator indirect current; The piezoelectric constant sector-meeting produces along its dilatation radially; Because piezoelectric ceramic and tinsel are bonded to one, and the radial expansion of piezoelectric ceramic and tinsel is different, so when piezoelectric ceramic produces dilatation radially; Tinsel also can produce dilatation; And flexible direction and piezoelectric ceramic are opposite, and then piezoelectric vibrator will inevitably produce vertically the reciprocal deformation vibration of (normal orientation of piezoelectric ceramic), the power source of piezoelectric vibrator as piezoelectric pump; Along with the axially back and forth deformation vibration of piezoelectric vibrator, thereby cause the volume cyclically-varying of piezoelectric pump pump chamber.Piezoelectric vibrator produces axial vibration under inverse piezoelectric effect, cause that pump chamber changes; Generally can an operation cycle of piezoelectric pump be divided into two stages: arrive upper dead center (maximum displacement of piezoelectric vibrator away from equilibrium location outside pump chamber) through the equilibrium position from lower dead centre (maximum displacement of piezoelectric vibrator away from equilibrium location in pump chamber) and be the suction journey stage of pump; Arriving lower dead centre from upper dead center through the equilibrium position is the scheduling stage of pump.When piezoelectric vibrator moves to upper dead center from lower dead centre; Be pump chamber from minimum to maximum conversion process, on one side of piezoelectric pump, fluid directly gets into pump chamber from first connectivity slot; And the another side fluid gets into pump chamber through Archimedes spiral stream pipe or get into pump chamber through second connectivity slot; In this process, the flow direction of fluid in Archimedes spiral stream pipe is the direction that the curvature of this helical flow pipe reduces gradually; When piezoelectric vibrator moves to lower dead centre from upper dead center, promptly to minimum conversion process, fluid discharges from pump chamber pump chamber from maximum, and fluid is during through Archimedes spiral stream pipe, is the direction that the curvature of helical flow pipe increases gradually.Because the variation of curvature is different, it is different with the influence of spin coriolis force to receive earth coriolis force, and curvature increases gradually;, the resistance that fluid receives increases gradually, and curvature reduces gradually; Resistance reduces gradually, and fluid mobile resistance that receives on the travel directions of managing through Archimedes spiral stream is different so, and fluid is managed the flow to the pump chamber inflow from Archimedes spiral stream on one side so; With the flow that flows out to another side from pump chamber will be different, one side make and have the another side that flow to pump of a net flow in the whole cycle from pump, when piezoelectric vibrator continuous shaking; Fluid will demonstrate one-way flow on macroscopic view, realize the function of pump.
In like manner, in the Archimedes spiral stream pipe Valveless piezoelectric pump of present technique scheme, two Archimedes spiral stream pipes are arranged, when promptly first, second Archimedes spiral flows pipe; Likewise, piezoelectric ceramic and tinsel as the two poles of the earth, when the piezoelectric vibrator indirect current; The piezoelectric constant sector-meeting produces along its dilatation radially; Because piezoelectric ceramic and tinsel are bonded to one, and the radial expansion of piezoelectric ceramic and tinsel is different, so when piezoelectric ceramic produces dilatation radially; Tinsel also can produce dilatation; And flexible direction and piezoelectric ceramic are opposite, and then piezoelectric vibrator will inevitably produce vertically the reciprocal deformation vibration of (normal orientation of piezoelectric ceramic), the power source of piezoelectric vibrator as piezoelectric pump; Along with the axially back and forth deformation vibration of piezoelectric vibrator, thereby cause the volume cyclically-varying of piezoelectric pump pump chamber.Because the motion of fluid receives earth self-rotation; And fluid self also can produce coriolis force along Archimedes spiral stream pipe when moving; Counterclockwise and the right handed fluid in edge is produced different effects, make from fluid inlet inflow and inequality, and the volume size of inflow or effluent fluid is inversely proportional to the flow resistance size that flows pipe from the suffered resistance of the fluid of fluid output outflow; So when the pump chamber volume increases; Fluid is from first Archimedes spiral stream pipe and second Archimedes spiral stream pipe inflow pump chamber, and piezoelectric pump was in and inhaled the journey stage this moment, but inequality from the fluid volume of two stream pipe inflow pump chambers; When the pump chamber volume reduced, fluid was managed the outflow pump chamber from first Archimedes spiral stream pipe and second Archimedes spiral stream, and this moment, piezoelectric pump was in the discharge stage, but inequality from the fluid volume of two stream pipe outflow pump chambers; Analysis is managed when piezoelectric pump is in the suction and the stage of discharge from two streams; How much may be summarized to be of the fluid volume that flows into and flow out: be in sucting stage at piezoelectric pump; The stream pipe that the incoming fluid volume is many, then piezoelectric pump be in discharge during the stage volume of effluent fluid few; Be in the few stream pipe of sucting stage incoming fluid volume at piezoelectric pump, then piezoelectric pump be in discharge during the stage volume of effluent fluid many; See that from macroscopic view piezoelectric pump always makes fluid flow pipe from one and flows into, and manages outflow from another stream, thereby has realized the one-way flow of fluid, has realized the function of pump.
Beneficial effect: the Valveless piezoelectric pump of the utility model is simple in structure, and simple installation can be produced in batches; Flow resistance is little, thereby makes the effect performance of key position helical flow pipe of the whole pump housing ultimate attainment, has improved pressure reduction and has increased flow; Simultaneously, Archimedes spiral stream pipe wherein plays the effect of carrying out the fluid heat radiation, makes Archimedes spiral stream pipe Valveless piezoelectric pump of the present invention especially be useful under the environment to magnetic-field-sensitive; Valveless piezoelectric pump of the present invention also has the effect of stirring, and is used for the mix of different liquids; Because Archimedes spiral stream pipe has the effect of stabilized fluid, fluid is mobile more stable when making pump housing outlet, is beneficial to and carries out the control that flow is supplied with in the using process.

Described first Archimedes spiral stream pipe 6 is connected with pump chamber 4 through second connectivity slot 10, and owing to the transitional function of second connectivity slot 10, the flow resistance of fluid in the stream pipe reduces greatly like this.
As shown in Figure 5, first Archimedes spiral stream pipe 6 of present embodiment is considered the volume of present embodiment piezoelectric pump for being the helical flow pipe that center and starting point counterclockwise are provided with fluid inlet 8, and the angle of first Archimedes spiral stream pipe 6 is 0 ° to 360 °.Fluid inlet 8 and fluid output 9 are separately positioned on the both sides of pump chamber 4, and for obtaining effect preferably, the center line that the two can pump chamber 4 is symmetrical, and promptly described first connectivity slot 7 and second connectivity slot 10 are that symmetry axis is symmetrical with the pump chamber center line.
Like Fig. 4, Fig. 6, shown in Figure 7; Pump chamber 4 cross sections of present embodiment are rounded; First groove 41 by being arranged on the lower cover 1 is formed with second groove, 42 sealings that are arranged on the loam cake 2; Described piezoelectric vibrator 5 is contained in second groove in 42, piezoelectric vibrator 5 generally by the piezo-electric sheet of circle and the folded system of resilient copper sheet forms and the diameter of piezoelectric vibrator less than the diameter of copper sheet; Second groove, 42 edges are stepped.

The Archimedes spiral of present embodiment stream pipe Valveless piezoelectric pump working procedure is following: piezoelectric ceramic and tinsel as the two poles of the earth; When piezoelectric vibrator 5 indirect currents, the piezoelectric constant sector-meeting produces along its dilatation radially, because piezoelectric ceramic and tinsel are bonded to one; And the radial expansion of piezoelectric ceramic and tinsel is different; So when piezoelectric ceramic produced dilatation radially, tinsel also can produce dilatation, and flexible direction is opposite with piezoelectric ceramic; Then piezoelectric vibrator 5 will inevitably produce vertically the reciprocal deformation vibration of (normal orientation of piezoelectric ceramic); The power source of piezoelectric vibrator,, thereby cause the volume cyclically-varying of piezoelectric pump pump chamber along with the axially back and forth deformation vibration of piezoelectric vibrator as piezoelectric pump.Piezoelectric vibrator 5 produces axial vibration under inverse piezoelectric effect, cause that pump chamber changes; Be divided into two stages to an operation cycle of pump: arrive upper dead center (maximum displacement of piezoelectric vibrator 5 away from equilibrium location outside pump chamber 4) through the equilibrium position from lower dead centre (maximum displacement of piezoelectric vibrator 5 away from equilibrium location in pump chamber 4) and be the suction journey stage of pump; Arriving lower dead centre from upper dead center through the equilibrium position is the scheduling stage of pump.When pump was in the suction journey, it is big that pump chamber 4 volumes become, and pressure diminishes; Fluid under suction function in first connectivity slot 7 and second connectivity slot 10 flows in pump chamber 4, manages 6 o'clock through Archimedes spiral stream from the fluid that fluid inlet 8 flows to, owing to receive the influence of earth coriolis force and spin coriolis force; The line curvature changing direction of the profile line of Archimedes spiral stream pipe reduces gradually, and relatively and the process that increases gradually of Archimedes spiral line curvature, the mobile obstacle of convection cell is little; The flow that gets into pump chamber 4 so is big relatively, and when pump got into scheduling, pump chamber 4 volumes diminished; Fluid under pressure in the pump chamber 4 flows out to the both sides connectivity slot, when from pump chamber 4 to Archimedes spiral stream pipe 6 flowing fluids during through Archimedes spiral stream pipe be the process that the curvature of Archimedes spiral increases gradually owing to receive the influence of earth coriolis force and the effect of spin coriolis force; Archimedes spiral curvature reduces gradually relatively; The obstruction degree of Archimedes spiral stream pipe 6 convection cells is big this moment, and the flow that flows out to Archimedes spiral stream pipe 6 from pump chamber 4 so will be less relatively, will produce a difference in flow in the process that comes and goes; Because pump chamber 4 suction journeys are equal basically with the scheduling change in volume; Will make the flow that is flowed out to first connectivity slot 7 by pump chamber 4 greater than the flow that is flowed into to pump chamber 4 by second connectivity slot 10 so, the whole cycle can produce the net flow of a unidirectional movement, when piezoelectric vibrator 5 continuous shakings; Fluid just shows one-way flow on macroscopic view, thereby forms the function of pump.
Embodiment two: the main structure of present embodiment and embodiment one are basic identical, and different is to contain two Archimedes spiral stream pipes in the present embodiment, and promptly first Archimedes spiral stream pipe, 6 and second Archimedes spiral stream pipe 11.As shown in Figure 8; In the present embodiment; First Archimedes spiral flows pipe 6 for being the helical flow pipe that center and starting point counterclockwise are provided with fluid inlet 8, and second Archimedes spiral stream pipe 11 is to be the helical flow pipe of center and the setting of starting point clockwise direction with fluid output 9.Fluid inlet 8 is symmetrical with symmetry axis in the center line of pump chamber 4 with fluid output 9, and correspondingly, first Archimedes spiral stream pipe, 6 and second Archimedes spiral stream pipe 11 is also symmetrical with symmetry axis in the center line of pump chamber 4.
During the Archimedes spiral of present embodiment stream pipe Valveless piezoelectric pump work, piezoelectric ceramic and tinsel as the two poles of the earth, when piezoelectric vibrator 5 indirect currents; The piezoelectric constant sector-meeting produces along its dilatation radially; Because piezoelectric ceramic and tinsel are bonded to one, and the radial expansion of piezoelectric ceramic and tinsel is different, so when piezoelectric ceramic produces dilatation radially; Tinsel also can produce dilatation; And flexible direction and piezoelectric ceramic are opposite, and then piezoelectric vibrator 5 will inevitably produce vertically the reciprocal deformation vibration of (normal orientation of piezoelectric ceramic), the power source of piezoelectric vibrator 5 as piezoelectric pump; Along with the axially back and forth deformation vibration of piezoelectric vibrator, thereby cause the volume cyclically-varying of pump chamber 4.Because the motion of fluid receives earth self-rotation; And fluid self also can produce coriolis force along Archimedes spiral stream pipe when moving; Counterclockwise and the right handed fluid in edge is produced different effects, make from fluid inlet inflow and inequality, and the volume size of inflow or effluent fluid is inversely proportional to the flow resistance size that flows pipe from the suffered resistance of the fluid of fluid output outflow; So when pump chamber 4 volumes increase; Fluid is from first Archimedes spiral stream pipe, 6 and second Archimedes spiral stream pipe, 11 inflow pump chambers 4, and piezoelectric pump was in and inhaled the journey stage this moment, but inequality from the fluid volume of two stream pipe inflow pump chambers; When pump chamber 4 volumes reduced, fluid was managed 11 from first Archimedes spiral stream pipe, 6 and second Archimedes spiral stream and is flowed out pump chambers 4, and this moment, piezoelectric pump was in the discharge stage, but inequality from the fluid volume of two stream pipe outflow pump chambers; Analysis is at piezoelectric pump from two stream pipes and sucks and during the stage of discharge, flow into and how much may be summarized to be of the fluid volume that flows out: be in sucting stage at piezoelectric pump, the incoming fluid volume is many, then piezoelectric pump be in discharge during the stage volume of effluent fluid few; Being in sucting stage at piezoelectric pump is that the incoming fluid volume is few, then piezoelectric pump be in discharge during the stage volume of effluent fluid many; See that from macroscopic view piezoelectric pump always makes fluid flow pipe from one and flows into, and manages outflow from another stream, thereby has realized the one-way flow of fluid, has realized the function of pump.
