Be provided with microprocessor, negative pressure pump in described aspirator main body, aspirator main body outside is provided with the control button, and negative pressure pump and control button are electrically connected to microprocessor respectively, and negative pressure pump is by pipeline connected sucking pipe joint.
Be connected with reversal valve on pipeline between described negative pressure pump and suction attachment.
Be provided with the battery into each components and parts power supply in described aspirator main body.
Beneficial effect of the present invention is: the present invention includes the aspirator main body, be connected to the suction attachment on the aspirator main body, pipette, the aspirator main body is set in the pipette outside, the top of pipette closely is connected with suction attachment, aspirator main body of the present invention is set in the outside operating grip that forms of pipette, during operation, be equivalent to directly be held in the enterprising line operate of pipette with hand, operational motion and Position Control are accurate, convenient, more convenient operation, smooth and easy, steadily, flexibly, can not rock, reduce the operate miss phenomenon, and can greatly reduce the length of auxiliary aspirator integral body, thereby reduced volume, take operating space and parking space is little, occasion in little spaces such as Biohazard Safety Equipments is easy to operate, in addition, suction attachment is hinged on the aspirator main body, aspirator main body Unscrew and suction attachment can be formed to certain angle, and the aspirator main body just can not affect the imbibition operation of part on pipette like this, can draw darker liquid.
The accompanying drawing explanation:
Fig. 1 is the structural representation of existing auxiliary aspirator.
Fig. 2 is structural representation of the present invention.
Fig. 3 is schematic cross-section of the present invention.
Fig. 4 is the structural representation that aspirator main body of the present invention is opened.
Fig. 5 is structure principle chart of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing, the present invention is further illustrated, see shown in Fig. 2～5, auxiliary aspirator, it includes aspirator main body 1, is connected to suction attachment 2, pipette 3 on aspirator main body 1, aspirator main body 1 is set in pipette 3 outsides, and the top of pipette 3 closely is connected with suction attachment 2.Aspirator main body 1 is positioned at the position of pipette 3 near top, can reduce the height of auxiliary aspirator integral body, thereby reduce volume.
Aspirator main body 1 lateral surface is along vertically offering the container cavity 11 that holds pipette 3, container cavity 11 runs through the aspirator main body, and Shang Xia 1 two ends, be that container cavity 11 is the cavitys to aspirator main body 1 lateral surface opening, pipette 3 is arranged in container cavity 11, can directly see the pipette 3 of the inside by the container cavity 11 of open type, prevent that aspirator main body 1 from blocking the scale on pipette 3.The lateral cross section profile of aspirator main body 1 is U-shaped structure, conveniently holds, safe and reliable.Suction attachment 2 is arranged in container cavity 11, makes the top of pipette 3 can be covered by container cavity 11, reduces the volume of auxiliary aspirator integral body.
Because aspirator main body 1 is set in, pipette 3 is outside can reduce the length that pipette 3 stretches out, can affect the degree of depth of pipette 3 imbibitions, for avoiding above problem, suction attachment 2 of the present invention is hinged on aspirator main body 1, with the container cavity 11 of open type, coordinate, 1 rotation of aspirator main body can be opened with suction attachment 2 and formed certain angle along container cavity 11 openings, aspirator main body 1 just can not affect the imbibition operation of part on pipette 3 like this, the length that pipette 3 stretches out can be do not reduced, darker liquid can be drawn.
Be provided with microprocessor 4, negative pressure pump 5 in aspirator main body 1, aspirator main body 1 outside is provided with controls button 6, and negative pressure pump 5 and control button 6 are electrically connected to microprocessor 4 respectively, and negative pressure pump 5 is by pipeline connected sucking pipe joint 2.Control button 6 and be arranged on the one or both sides of container cavity 11 openings on aspirator main body 1, handled easily.Be connected with solenoid directional control valve 7 on pipeline between negative pressure pump 5 and suction attachment 2, by reversal valve 7, control imbibition and discharge opeing.Be provided with the battery 8 into each components and parts power supply in aspirator main body 1.
Aspirator main body 1 of the present invention is set in the outside operating grip that forms of pipette 3, during operation, be equivalent to directly be held in the enterprising line operate of pipette 3 with hand, operational motion and Position Control are accurate, convenient, more convenient operation, smooth and easy, steady, flexible, can not rock, reduce the operate miss phenomenon; And with existing auxiliary aspirator, compare, in the situation that use identical pipette 3, the entire length of auxiliary aspirator of the present invention is 5cm, is highly 38cm, and width is 5cm, and taking like this volume is 950cm
3, entire length has reduced 66.7%, and volume has reduced 70.5%, can greatly reduce whole length, thereby has reduced volume, takies operating space and parking space is little, easy to operate in the occasion in the little spaces such as Biohazard Safety Equipment; When need are drawn darker liquid, aspirator main body 1 Unscrew and suction attachment 2 are formed to certain angle, aspirator main body 1 just can not affect the imbibition operation of part on pipette 3 like this, make pipette 3 stretch out longer length, when only needing to draw more shallow liquid, aspirator main body 1 rotation is folded and is set in pipette 3 outsides pipette 3 is folded in container cavity 11, make 3 of pipettes stretch out a part of length, use flexibly, convenient.
Certainly, the above is only preferred embodiment of the present invention, and the equivalence of doing according to the described structure of patent claim of the present invention, feature and principle therefore all changes or modifies, and is included in patent claim of the present invention.
