Abstract

A kind of piston type dispenser provided by the utility model, including outer tube, ejector sleeve, outlet tube, inlet tube;One end of the ejector sleeve is stretched into outer tube and sliding, the other end stretch out outer tube top in outer tube;The outlet tube is set to outer tube bottom end, and outlet tube is equipped with the first check valve;The inlet tube is connect with outer tube lower part, and inlet tube is equipped with the second check valve.The piston type dispenser is of simple structure and low cost, it can be achieved that continuous liquid separation, easy to operate, substantially increases liquid separation efficiency.

Description

A kind of piston type dispenser
Technical field
The utility model belongs to field of analytic instrument, more particularly to a kind of piston type dispenser.
Background technology
In examining detection work, it is often necessary on a small quantity or be quantitatively transferred to refer to by the liquid of acquisition using pipettor It is common for example using pipette transfer liquid in fixed container;However, when the liquid for needing to shift, needing manually will pipe Mouth stretches into container, and liquid is sucked out from container, then nozzle is put in container to be transferred and releases liquid, and use is not square Just, it is difficult to continuous liquid relief.
Utility model content
Technical problem:In order to solve the defects of prior art, the utility model provides a kind of piston type dispenser.
Technical solution:A kind of piston type dispenser provided by the utility model, including outer tube, ejector sleeve, outlet tube, feed liquor Pipe;One end of the ejector sleeve is stretched into outer tube and sliding, the other end stretch out outer tube top in outer tube;The outlet tube is set to outer Tube bottom end, and outlet tube is equipped with the first check valve;The inlet tube is connect with outer tube lower part, and inlet tube is equipped with the second list To valve.
As an improvement, further including piston, the piston is set to the bottom of ejector sleeve.
It is improved as another kind, further includes holder 8, holder 8 is equipped with fixture 9, and 8 top of holder is equipped with screw motor 10; The outer tube is fixed on by fixture 9 on holder 8, and the screw motor 10 is connect with the top of ejector sleeve.
Advantageous effect:Piston type dispenser provided by the utility model is of simple structure and low cost, it can be achieved that continuous point Liquid, it is easy to operate, substantially increase liquid separation efficiency.
Description of the drawings
Fig. 1 is the piston type knockout structural representation of embodiment 1.
Fig. 2 is the piston type knockout structural representation of embodiment 1.
Specific implementation mode
The utility model piston type dispenser is further illustrated below.
Embodiment 1
Piston type dispenser is shown in Fig. 1, including outer tube 1, ejector sleeve 2, outlet tube 3, inlet tube 4;One end of ejector sleeve 2 is stretched into outer Sliding, the other end stretch out 1 top of outer tube in pipe 1 and in outer tube 1;Outlet tube 3 is set to 1 bottom end of outer tube, and outlet tube 3 is equipped with First check valve 5;Inlet tube 4 is connect with 1 lower part of outer tube, and inlet tube 4 is equipped with the second check valve 6.
The liquid flow direction of first check valve 5 is from inlet tube 4 to outer tube 1, the liquid flow direction of the second check valve 6 is certainly outer To outlet tube 3 in pipe 1;For example, the first check valve 5, the second check valve 6 are diaphragm type one-way valve.
The device is when in use:
1 is put into one end of inlet tube 4 in the liquid container for waiting for liquid separation, and outlet tube 3 is placed in target container;
2 smoke ejector sleeve 2, due to suction, so that the first check valve 5 is opened, the closing of the second check valve 6, due to check valve Effect, wait for that the liquid in the liquid container of liquid separation is inhaled into outer tube 1;
3 push ejector sleeve 2, due to thrust, so that the first check valve 5 is closed, the unlatching of the second check valve 6, due to check valve Effect, wait for that the liquid in the liquid container of liquid separation is admitted in target container.
Embodiment 2
Piston type dispenser is shown in Fig. 2, including outer tube 1, ejector sleeve 2, outlet tube 3, inlet tube 4, piston 7, holder 8.
One end of ejector sleeve 2 is stretched into outer tube 1 and sliding, the other end stretch out 1 top of outer tube in outer tube 1;Outlet tube 3 is set In 1 bottom end of outer tube, and outlet tube 3 is equipped with the first check valve 5;Inlet tube 4 is connect with 1 lower part of outer tube, and inlet tube 4 is equipped with Second check valve 6;The bottom of ejector sleeve 2 is equipped with piston 7.
Holder 8 is equipped with fixture 9, and 8 top of holder is equipped with screw motor 10;Outer tube 1 is fixed on holder 8 by fixture 9 On, screw motor 10 is connect with the top of ejector sleeve 2.
