Abstract
A kind of new liquid-transfering device is the utility model is related to, including：Control cabinet；It is installed on aspiration pump inside control cabinet and is connected to the fixed frame of control cabinet；Installed in fixed frame center, the pipette placed vertically；It is mounted side by side in the optoelectronic switch in fixed frame center, which is included respectively positioned at the transmitting terminal and receiving terminal of pipette horizontal direction both sides on fixed frame, and the light and pipette dosage line of transmitting terminal flush；Adjustable speed aspiration pump, the optoelectronic switch that control pumping pump startup is closed, optoelectronic switch are produced and exported（on/off）Control signal.The utility model treats dosage needed for liquid level arrival, optoelectronic switch output switching signal opens and closes at random to aspiration pump, aspiration pump, realizes automatic sampling using adjustable speed aspiration pump collection liquid sample.
Description
Technical field
It the utility model is related to engineering detecting, chemical analysis technology field, and in particular to liquid quantitative sampling, which is used up, establishes by cable
Pass type liquid-transfering device.
Background technology
During liquid sampling, it usually needs draw, shift and ooze sample in liquid storing barrel using pipette.Specifically
, first take liquid end to be perpendicularly inserted into below liquid storing barrel liquid level in pipette, upper port forms negative pressure, promotes to be filled with pipette
Required liquid, until the dosage side needed stops suction.Then, pipette upper port is closed, proposes that pipette to elsewhere, is opened
Pipette upper port, liquid in free effuser.Common operating technology be people in order to control, operating efficiency is not high, and precision is not allowed
It is easy to control.
In liquid and pipetting processes is determined, the measure of closing pipette upper port is closed using finger, it is not easy to which closing is tight
It is close.
In addition, level control, performance accuracy is limited by personnel's qualification and operating habit.
Utility model content
In view of the deficiencies of the prior art, the utility model is intended to provide one kind using optoelectronic switch control aspiration pump completion
Operation, it can be used in sensing the liquid level in pipette, automatic open close aspiration pump, while have higher accuracy.
To achieve the above object, the utility model adopts the following technical solution：
A kind of new liquid-transfering device, including：
Workbench；
Stablize the liquid storing barrel being positioned on workbench；
Control cabinet, including start button, stop button and speed governing button；
The aspiration pump being installed on inside control cabinet；
Fixed frame, is connected to control cabinet, for fixing the pipette of optoelectronic switch and arranged orthogonal；
It is mounted side by side in the optoelectronic switch on fixed frame, which includes the transmitting terminal for being located at pipette both sides respectively
And receiving terminal, the light of transmitting terminal project direction and are overlapped with the dosage line direction of pipette；The optoelectronic switch is used to take liquid, arrive
Up to signal is sent to control cabinet respectively during dosage line, whether control cabinet is stopped according to signal control aspiration pump；
The beneficial effects of the utility model are：
Compared with the prior art, the utility model sets an optoelectronic switch just to realize that pipette starts to take liquid, sentences automatically
Disconnected dose profile simultaneously stops drawing immediately, and discharges a succession of operation procedure of liquid in pipe, realizes the automation of experiment
And accuracy.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Fig. 1 is the structure diagram of the utility model；
Wherein：1st, workbench；2nd, liquid storing barrel；3rd, pipette；4、5：Optoelectronic switch transmitting terminal and receiving terminal；6th, rubber is soft
Pipe；7th, fixed frame；8th, control cabinet；9th, aspiration pump；10th, start button；11st, stop button；12nd, speed governing button.
Embodiment
In the following, with reference to attached drawing and embodiment, the utility model is described further：
As shown in Figure 1, being a kind of new liquid-transfering device of the utility model, it includes pipette 3, optoelectronic switch transmitting terminal
4th, receiving terminal 5, rubber hose 6, control cabinet 8, aspiration pump 9.
Wherein, control cabinet 8 has gathered rubber hose 6, aspiration pump 9, start button 10, stop button 11, speed governing button 12,
Rubber hose 6 connects aspiration pump 9 and pipette 3, forms air-breathing and release pressure channel, and aspiration pump 9 receives photoelectric switching signal
Realize and open and close work, speed governing button 12 is used for realization artificial adjusting air-breathing speed as needed.
Optoelectronic switch includes transmitting terminal 4 and receiving terminal 5, and transmitting terminal 4 and receiving terminal 5 are respectively and fixedly installed to 7 water of fixed frame
Square to pipette both sides, formed a horizontal line of induction, click on start button 10 start sampling work after, 4 He of transmitting terminal
Receiving terminal 5 keeps path, and whole device is persistently sampled, and liquid level is persistently lifted in pipette, until liquid level reaches the line of induction
Position, blocks the connection of transmitting terminal 4 and receiving terminal 5, forms break signal, is then sent to aspiration pump 9, stops suction, so that
Completion is automatically stopped air-breathing work, then after clicking on stop button 11, aspiration pump stops state of holding one's breath, and discharges negative in pipette
Pressure, completes the work of release liquid.
In the utility model, a connecting portion, the transmitting terminal 4 of optoelectronic switch is arranged side by side in the by-level of fixed frame 7
It is removably attachable on connecting portion, by the height of the pipette dosage line of needs and transmitting terminal 41 and can connects with receiving terminal 5
The line of receiving end 42 highly overlaps, that is, ensures that pipette dosage line and the optoelectronic switch line of induction are highly consistent.
It will be apparent to those skilled in the art that technical solution that can be as described above and design, make other various
Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims
Within the scope of.
