Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
Fig. 1 ~ Fig. 3 is please referred to, the embodiment of the present invention includes:
A kind of anti-suck fluid injection set cup device, including hollow fluid injection a set of cups 1,1 bottom of fluid injection a set of cups is equipped with EPDM liquid injecting mouth 3.
Fluid injection a set of cups 1 includes: the upside a set of cups connector 4 for being covered in upper end, the downside a set of cups connector 5 for being covered in lower end；EPDM note
Liquid mouth 3 is installed on downside a set of cups connector 5, and fluid injection sealing bar 2 passes through upside a set of cups connector 4 and is inserted into fluid injection a set of cups 1.
Fluid injection sealing bar 2 is inserted into fluid injection a set of cups 1 and 3 phase of sealing mouth 16 and EPDM liquid injecting mouth of 2 lower end of fluid injection sealing bar
Cooperation；Fluid injection sealing bar 2 includes the hole opened up along axial direction, and be slidably matched inner sealing bar 14 in hole, inner sealing bar 14
Lower end is equipped with interior bar seal head 15.The upper end of inner sealing bar 14 is cooperated in a manner of piston in a plunger shaft independently of hole
Interior, plunger shaft is located in the inner sealing joint element for bar 13 of fluid injection sealing bar upper end, and the first interior bar interface is provided in plunger shaft
10 and the second interior bar interface 11.The piston head of the upper end setting cooperation plunger shaft of inner sealing bar 14,10 He of the first interior bar interface
Second interior bar interface 11 is opened in the two sides of piston head respectively.When the first interior bar interface accesses gas source, piston head is moved downward, because
This inner sealing bar moves down so that sealing mouth blocks liquid injecting mouth；When the second interior bar interface accesses gas source, piston head is moved upwards, because
This inner sealing bar moves up so that liquid injecting mouth is without blocking.
Be additionally provided in fluid injection sealing bar 2 be connected to hole vacuumize interface 12；It is additionally provided on fluid injection a set of cups 1 for inside it
The liquid injection port 9 of fluid injection；The positive/negative-pressure interface 8 being additionally provided on a set of cups connector of upside inside connection fluid injection a set of cups；Fluid injection set
A set of cups mounting plate 6 is additionally provided on cup.
Working principle:
Fluid injection sealing bar seals fluid injection a set of cups, and interface is vacuumized in fluid injection sealing bar and extracts inside battery vacuum, liquid injection port injection
Liquid, the first interior bar interface and the second interior bar Interface Controller inner sealing bar move up and down, to seal in fluid injection sealing bar
Portion, liquid reach rear fluid injection sealing bar and rise, and can reach pumping inside battery vacuum and carry out simultaneously with fluid injection.Meanwhile fluid injection seals
Interior bar seal head prevents liquid suck-back to being sealed inside fluid injection sealing bar before bar rises.
In conclusion many fluid injections currently on the market cannot carry out simultaneously with battery vacuum is taken out, and fluid injection after progress simultaneously
The bad guarantee of precision, and the present apparatus is carried out for taking out inside battery vacuum with fluid injection simultaneously, in injection needle fluid injection to fluid injection a set of cups,
Fluid injection sealing bar seals a set of cups, and takes out vacuum in battery, can prevent inside liquid suck-back to fluid injection sealing bar.Fluid injection sealing bar is close
Big envelope cup simultaneously extracts vacuum in battery by fluid injection sealing bar, and spout reservoir, fluid injection sealing bar is detached from after the completion of fluid injection, liquid
It is inhaled into battery, due to vacuumizing inside fluid injection sealing bar, liquid can seal mouth suck-back into fluid injection sealing bar by a set of cups
Portion, the present apparatus can be by interior bar interface and interior bar Interface Controller inner sealing bar motion seal fluid injection sealing bar inside, reach
A set of cups seal after mouth is detached from liquid can not suck-back into fluid injection sealing bar internal action.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
