3therefore volume ratio is larger, take operating space and parking space is large, in the occasion inconvenient operation in the little spaces such as Biohazard Safety Equipment, and due to handle and pipette be mutually away from, indirectly drive pipette to move by handle through aspirator main body, operational motion and position are not easy to control, operation has some setbacks and not steadily, easily rocks and occur operate miss phenomenon.
Summary of the invention:
Object of the present invention be exactly for prior art exist deficiency and a kind of auxiliary aspirator reducing volume, handled easily is provided.
To achieve these goals, the technical solution used in the present invention is:
Auxiliary aspirator, it includes aspirator main body, the suction attachment be connected in aspirator main body, pipette, aspirator main body is set in pipette outside, the top of pipette and suction attachment compact siro spinning technology.
Described aspirator main body is positioned at the position of pipette near top.
Described aspirator main body lateral surface vertically offers the container cavity holding pipette, and pipette is arranged in container cavity.
The transverse cross-sectional profile of described aspirator main body is U-shaped structure.
Described suction attachment is arranged in container cavity
Described suction attachment is hinged in aspirator main body.
Be provided with microprocessor, negative pressure pump in described aspirator main body, aspirator body exterior is provided with control button, and negative pressure pump and control button are electrically connected with microprocessor respectively, and negative pressure pump is by pipeline connected sucking pipe joint.
Pipeline between described negative pressure pump and suction attachment is connected with reversal valve.
The battery of powering for each components and parts is provided with in described aspirator main body.
Beneficial effect of the present invention is: the present invention includes aspirator main body, be connected to the suction attachment in aspirator main body, pipette, aspirator main body is set in pipette outside, the top of pipette and suction attachment compact siro spinning technology, aspirator main body of the present invention is set in pipette outside and forms operating grip, be equivalent to during operation directly be held in the enterprising line operate of pipette with hand, operational motion and position control accurate, convenient, more convenient operation, smooth and easy, steadily, flexibly, can not rock, reduce operate miss phenomenon, and the length of auxiliary aspirator entirety can be greatly reduced, thus reduce volume, take operating space and parking space is little, easy to operate in the occasion in the little spaces such as Biohazard Safety Equipment, in addition, suction attachment is hinged in aspirator main body, aspirator main body Unscrew and suction attachment can be formed certain angle, and such aspirator main body would not affect the imbibition operation of pipette upper part, can draw darker liquid.
Accompanying drawing illustrates:
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.
Detailed description of the invention:
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, the suction attachment 2 be connected in aspirator main body 1, pipette 3, it is outside that aspirator main body 1 is set in pipette 3, the top of pipette 3 and suction attachment 2 compact siro spinning technology.Aspirator main body 1 is positioned at the position of pipette 3 near top, can reduce the height of auxiliary aspirator entirety, thus reduces volume.
Aspirator main body 1 lateral surface vertically offers the container cavity 11 holding pipette 3, container cavity 11 runs through aspirator main body about 1 two ends, namely container cavity 11 is the cavitys to aspirator main body 1 lateral surface opening, pipette 3 is arranged in container cavity 11, directly can be seen the pipette 3 of the inside by the container cavity 11 of open type, prevent aspirator main body 1 from blocking scale on pipette 3.The transverse cross-sectional 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 entirety.
The length that pipette 3 stretches out can be reduced because aspirator main body 1 is set in pipette 3 outside, the degree of depth of pipette 3 imbibition can be affected, for avoiding above problem, suction attachment 2 of the present invention is hinged in aspirator main body 1, coordinate with the container cavity 11 of open type, aspirator main body 1 can be rotated to open along container cavity 11 opening and form certain angle with suction attachment 2, such aspirator main body 1 would not affect the imbibition operation of pipette 3 upper part, the length that pipette 3 stretches out can not be 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 and controls button 6, and negative pressure pump 5 and control button 6 are electrically connected with microprocessor 4 respectively, and negative pressure pump 5 is by pipeline connected sucking pipe joint 2.Controlling button 6 is arranged on the one or both sides of container cavity 11 opening in aspirator main body 1, handled easily.Pipeline between negative pressure pump 5 and suction attachment 2 is connected with solenoid directional control valve 7, controls imbibition and discharge opeing by reversal valve 7.The battery 8 of powering for each components and parts is provided with in aspirator main body 1.
Aspirator main body 1 of the present invention is set in pipette 3 outside and forms operating grip, be equivalent to during operation directly be held in the enterprising line operate of pipette 3 with hand, operational motion and position control accurately, convenient, more convenient operation, smooth and easy, steady, flexible, can not rock, reduce operate miss phenomenon; And compared with existing auxiliary aspirator, when using identical pipette 3, the entire length of auxiliary aspirator of the present invention is 5cm, is highly 38cm, and width is 5cm, and taking volume is like this 950cm
3, entire length decreases 66.7%, and volume decreases 70.5%, can greatly reduce overall length, thus reduce 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 darker liquid need be drawn, aspirator main body 1 Unscrew and suction attachment 2 are formed certain angle, such aspirator main body 1 would not affect the imbibition operation of pipette 3 upper part, pipette 3 is made to stretch out longer length, when only needing to draw more shallow liquid, aspirator main body 1 is rotated to fold and is set in pipette 3 outside pipette 3 is folded in container cavity 11, make pipette 3 only stretch out the length of a part, use flexibly, convenient.
Certainly, the above is only preferred embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
