Embodiment
Below in conjunction with the drawings and specific embodiments technical solution of the present invention being described in detail, further understanding purpose of the present invention, scheme and effect, but is not the restriction as claims protection domain of the present invention.
Consult Fig. 2, it is the structural drawing of the peristaltic pump of first embodiment of the invention, peristaltic pump as shown in the figure comprises motor 10, elastic pump tubes (radical of elastic pump tubes herein is identical with the group number of driving wheel group 30), cooperates the wheels adapting device 40 that makes this elastic pump tubes distortion by the driving wheel group 30 of these motor 10 driven rotary and with this driving wheel group.
Above-mentioned pump impeller 31 is by bearing pin 38, catch 39 location, pump impeller 32 is by being arranged on catch 311 and screw 310 location on output shaft 11 1 ends, (this partition 37 can be separately positioned in the groove of pump impeller 31,32 end faces also to be provided with partition 37 between two pump impellers, but be not limited to this), this partition 37 is positioning roller 34 on the one hand, reduces by two frictions between the roller on the other hand.
Peristaltic pump working principle among this embodiment is: suppose that one-way element 35 is locking state clockwise, one-way element 36 is a locking state counterclockwise so.When the output shaft 11 of motor clockwise rotated, one-way element 36 was a slipping state, pump impeller 32 transfixions, and one-way element 35 is a locking state, can drive pump impeller 31 and rotate, can drive the liquid of elastic pump tubes 21 this moment.As a same reason, when the output shaft 11 of motor rotated counterclockwise, one-way element 35 was a slipping state, pump impeller 31 transfixions, and one-way element 36 is a locking state, can drive pump impeller 32 and rotate, can drive the liquid of elastic pump tubes 22 this moment.
The above-mentioned pump impeller that only provided is two a example, in actual use, the pump impeller number is not limited to two, its can for three, four or more than, but no matter how many numbers is, its working principle is identical with the working principle of two pump impellers, as, when pump impeller is three, one-way element on one of them pump impeller is clockwise (or counterclockwise), and the one-way element on other two pump impellers is counterclockwise (or clockwise), like this, the pump impeller of clockwise one-way element correspondence is a control road, and the pump impeller of counterclockwise one-way element correspondence is a control road.When the output shaft 11 of motor clockwise rotated, anticlockwise two one-way elements were slipping state, the pump impeller transfixion that it is corresponding; And clockwise one-way element is a locking state, and it can drive corresponding pump impeller and rotate, to drive the liquid in the elastic pump tubes.As a same reason, when the output shaft 11 of motor rotated counterclockwise, clockwise two one-way elements were slipping state, the pump impeller transfixion that it is corresponding; And anticlockwise one-way element is a locking state, and it can drive corresponding pump impeller and rotate, to drive the liquid in the elastic pump tubes.Same, when pump impeller was four, the one-way element on one of them or two pump impellers was clockwise, one-way element on the remaining pump impeller is counterclockwise, like this, the pump impeller of clockwise one-way element correspondence is a control road, and the pump impeller of counterclockwise one-way element correspondence is a control road.
Further, be example still with the driving wheel group that comprises two pump impellers, roller on two pump impellers articulate the axle center to output shaft 11 distances of shaft centers of motor 10 from can be identical (at this moment, under the identical situation of the elastic pump tubes thickness of correspondence, the flow sizes on two control roads are identical), also can be different (as shown in Figures 3 and 4, at this moment, under the identical situation of the elastic pump tubes thickness of correspondence, the flow on two control roads varies in size).Roller number on two pump impellers can equate (as shown in Figure 3, be all 6, certainly, the number of roller is not as limitation); Roller number on two pump impellers can not wait (as shown in Figure 4, wherein the roller number on the pump impeller is 6, and the number on another pump impeller is 8, and certainly, the number of roller is not as limitation) yet.
Also have, the above-mentioned example that only provides a corresponding elastic pump tubes of pump impeller, in actual use, be not limited thereto, as, pump impeller can corresponding two or above elastic pump tubes, is example with corresponding two elastic pump tubes of a pump impeller, and the thickness of these two elastic pump tubes can be the same or different.
Consult Fig. 5, Fig. 6 and Fig. 7, it is the peristaltic pump structural drawing of second embodiment of the invention, peristaltic pump structure among this embodiment and first embodiment's peristaltic pump structure are roughly the same, different is, thereby wheels adapting device 40 comprises the fixed block 40 ' of the joint 211,212 at fixing elastic pump tubes 21 two ends with these elastic pump tubes 21 tensions, in the present embodiment, fixed block 40 ' simultaneously fixedly the joint 221,222 at elastic pump tubes 22 two ends with elastic pump tubes 22 tension.Need to prove: though stretching herein and the fixed block of fixing two elastic pump tubes 21,22 are same fixed block, in actual use, it also can be the different fixing part; The fixed block of the joint 211,212 at fixedly elastic pump tubes 21 two ends herein is same fixed block, and in actual use, it also can be different fixed blocks; Same, the fixed block of the joint 221,222 at fixedly elastic pump tubes 22 two ends herein is same fixed block, in actual use, it also can be different fixed blocks.
Above-mentioned peristaltic pump mainly comprises the steps: when making
(1) motor 10 is set.
(2) on the output shaft 11 of motor 10, driving wheel group 30 is set.Wherein driving wheel group 30 can be as shown in Figure 2, comprise pump impeller 31,32, two above free rolling rollers are set on each pump impeller, roller 31,32 is arranged side by side on the output shaft 11 of motor 10 by unilateral bearing 35,36 respectively, and the installation direction of the unilateral bearing 35,36 of setting must be opposite.
(3) on the part outer rim of driving wheel group 30 around the step of elastic pump tubes.Comprise under the situation of two pump impellers that in the driving wheel group 30 that is provided with corresponding elastic pump tubes can be two, that is, and the corresponding elastic pump tubes of pump impeller.Specifically, elastic pump tubes is surrounded on the roller.
(4) setting cooperates the wheels adapting device that makes the elastic pump tubes distortion with driving wheel group 30.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
