Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, the present invention is based on the software pumps of dielectric elastomer driving, including hollow frame 1, frame 1 is in ballShape or elliposoidal (as shown in Figure 2)；1 one end of frame offers entrance 2, and the other end offers outlet 3；It is provided in frame 1Driving body 4；Driving body 4 uses dielectric elastomer, and the shape of driving body 4, size and frame 1 are adapted；It opens 4 one end of driving bodyEquipped with water inlet 5, the other end offers water outlet 6；The water inlet 5 of driving body 4 is fixed in the entrance 2 of frame 1, driving body 4Water outlet 6 is fixed in the outlet 3 of frame 1；The affixed water inlet pipe 7 of water inlet 5；The affixed outlet pipe 8 of water outlet 6；The shape of water inlet pipe 7Shape, size and entrance 2 are consistent；Shape, size and the outlet 3 of outlet pipe 8 are unanimously；List is provided on water inlet pipe 7 and outlet pipe 8To valve 9；4 surfaces externally and internally of driving body is coated with flexible electrode layer 14, and flexible electrode layer 14 uses graphite carbon paste；Two flexible electricalsOne end of guide wire a10, guide wire b13 are connected separately on pole layer 14；Guide wire a10, guide wire b13 use aluminium foil；GuidingLine a10, guide wire b13 the other end connect the two poles of the earth of same power supply 11, the voltage that power supply 11 loads is alternating voltage；Two softProperty 14 surface of electrode layer is all covered with insulating layer 12；The present invention can connect (as shown in Figure 3), can also be in parallel (such as Fig. 4 instituteShow)；It can also not only connect but also (as shown in Figure 5) in parallel；When software series connection of pumps, two adjacent softwares pump connected power supply 11Voltage amplitude is identical, the period is identical and phase difference is 180 °.
The present invention is based on the working principles of the software pump of dielectric elastomer driving are as follows: dielectric elastomer is a kind of electroactive poly-Object soft material is closed, dielectric elastomer has many advantages, such as that power foot, response are fast, electromechanical conversion efficiency is high and light inexpensive；Driving body 4Using dielectric elastomer, when power supply 11 exports forward voltage, the expansion of driving body 4, volume become larger, and internal pressure is less than extraneous bigAir pressure, to suck liquid by water inlet pipe 7 under the action of check valve 9；When power supply 11 exports backward voltage, driving body 4Diminution, volume become smaller, so that liquid be discharged by outlet pipe 8 under the action of check valve 9；In this way, as alternating source 11 hasThe output voltage of rule, the movement that driving body 4 regular can recycle sucking liquid, liquid is discharged；Software pump of the invention canSeries, parallel or existing series connection have parallel connection again；When software series connection of pumps, two adjacent softwares pump connected alternating source11 amplitudes are identical, the period is identical and phase difference is 180 °；Its operation principle and process is as described above.
The advantages of the present invention is based on the software pumps of dielectric elastomer driving are as follows: the driving body made of in dielectric elastomerUpper load alternating voltage and make driving body deformation occurs, to realize regular water suction draining movement；Also, volume of the present inventionIt is small, structure is simple, own wt is light, is not likely to produce noise, is at low cost；Also, it will not be worn working long hours,Long service life, maintenance cost are low.
