To describe the technology contents of the present invention, construction feature, the effect realized in detail, below in conjunction with embodiment and match somebody with somebody
Accompanying drawing is closed to be explained in detail.
As shown in Figure 1, Figure 2 and Figure 3, fluid injection cup device 100 of the present invention includes bar 2, pipeline 3 and contiguous block in cup 1, cup
4, the top of cup 1 is provided with bar 2 in cup top cover 11, the contiguous block 4 and cup and is arranged at the cup top cover 11；The cup 1
Bottom is provided with cup bottom 12, and liquid injecting mouth 5 is arranged at the cup bottom 12；Cup top cover 11 and cup bottom 12 one side can be covered
Together on the cup 1 to form the fluid injection chamber 13, on the other hand can be the contiguous block 4, cup in bar 2 and liquid injecting mouth 5
There is provided and carrier is installed.Reservoir channel 14 of the cup 1 provided with fluid injection chamber 13 and the connection fluid injection chamber 13, the reservoir channel
14 are in communication with the outside, and can be injected by the reservoir channel 14 into the fluid injection chamber 13 in battery fluid, the fluid injection chamber 13
Provided with inner tube 6, the lower end of said inner tube 6 close to the fluid injection chamber 13 inner bottom part and connected with the fluid injection chamber 13, it is and described
The upper end of inner tube 6 is connected with the contiguous block 4.The contiguous block 4 is fixed in the cup top cover 11, during the contiguous block 4 is
Sky and one end company for passing through connector 41 and the pipeline 3 provided with multiple connectors 41 for inserting and connecting, the contiguous block 4
It is logical.The other end of the pipeline 3 is connected with the liquid injecting mouth 5；The inside of bar 2 is provided with passage 21 in the cup, and passage 21 is from described
The import of the upper end of bar 2 extends to the lower end of bar 2 in the outlet of bottom side of the wall, the cup provided with plug 22, and the cup in cup
Bar 2 is on the cup top cover 11 being slidingly arranged at and central shaft and the central axis of said inner tube 6, and bar 2 is downward in the cup
It is first position when sliding into minimum point, is the second place when sliding into peak upwards；When bar 2 slides into first position in the cup,
The plug 22 is plugged in the upper end of said inner tube 6, so that the outlet of the passage 21 connects by wherein the one of the contiguous block 4
Interface 41 is connected with the pipeline 3；When bar 2 slides into the second place in the cup, the plug 22 leaves the upper of said inner tube 6
End, now, the outlet of the passage 21 blocks the contiguous block 4 from the connector 41 and the plug 22 in the contiguous block 4,
So that the passage 21 is disconnected with the pipeline 3, and said inner tube 6 is connected by the contiguous block 4 with the pipeline 3.
Again as shown in Fig. 2 the fluid injection cup device 100 also includes a spring 7, the spring 7 is arranged at bar 2 in the cup
Between the cup 1, so that the plug 22 of bar 2 leaves the upper end of said inner tube 6 in the cup, so as to so that in the cup
Bar 2 rises automatically in the case where not being stressed, and said inner tube 6 is connected by contiguous block 4 with the pipeline 3, reaches automatic
The purpose of fluid injection.
The first sealing ring 8 is provided between said inner tube 6 and the contiguous block 4, the middle part is provided with an accommodating hole 81, described
When plug 22 is plugged in the upper end of said inner tube 6, the plug 22 is placed in the accommodating hole 81.The energy of first sealing ring 8

Contiguous block 4 is connected.
Junction between the plug 22 and the pipeline 3 and the contiguous block 4 is respectively equipped with the second sealing ring 9.Institute
Stating the second sealing ring 9 can avoid interface from occurring gas leakage or leakage, it is ensured that the stability of fluid injection.
Again as shown in figure 3, the bottom of the fluid injection chamber 13 is in reverse taper 13a, the lower end of said inner tube 6 is located at the back taper
Body 13a bottom.Reverse taper 13a structure can be such that remaining fluid injection always focuses in the lower inlet of said inner tube 6, from
And be conducive to fluid injection complete, it is to avoid remain in fluid injection chamber 13, improve the accuracy of reservoir quantity.
Summary, the injection process of fluid injection cup device 100 of the present invention is described in detail below, as follows：
As shown in Fig. 2 before fluid injection, the liquid injecting mouth 5 is plugged in the liquid injection port of battery container, so that liquid injecting mouth 5 and electricity
Pond enclosure interior connection；Bar 2 is moved down by the pressure of vaccum-pumping equipment and compresses the spring 7 in the cup so that institute
State plug 22 to insert in the accommodating hole 81, at this moment, the plug 22 blocks the upper end outlet of said inner tube 6, and said inner tube 6 is not
Connected with the contiguous block 4；Meanwhile, the outlet of the passage 21 of bar 2 is connected with the connector 41 of the contiguous block 4 in the cup,
Connected so as to realize with the pipeline 3.Now, the battery container, liquid injecting mouth 5, pipeline 3, contiguous block 4 and the formation of passage 21 one
Path, the vaccum-pumping equipment is vacuumized to battery container inside.In addition, during vacuumizing, battery fluid is from institute
Reservoir channel 14 is stated to inject in the fluid injection chamber 13.
As shown in figure 4, when completing to vacuumize, the vaccum-pumping equipment is removed so that the pressure of bar 2 disappears in the cup
Lose, at this moment, under the restoring force effect of the spring 7, bar 2 is moved up in the cup, so that the plug 22 leaves institute
The outlet of the upper end of inner tube 6 is stated, the contiguous block 4 is left in the outlet of the passage 21, now, the passage 21 and contiguous block 4
Path cut-off, and said inner tube 6, contiguous block 4, pipeline 3 and liquid injecting mouth 5 formation one path.In the vacuum of the battery container
Under gas pressure in state and fluid injection chamber 13, the battery fluid in fluid injection chamber 13 passes through connection from the lower end of said inner tube 6
Block 4, pipeline 3 and liquid injecting mouth 5 are injected into the battery container, realize fluid injection.
Compared with prior art, because the present invention is by the way that said inner tube 6 is connected with contiguous block 4, and by the pipeline 3
One end is connected with the contiguous block 4, and the other end is connected with the contiguous block 4, then sets bar 2 in one glass, makes the bar 2 in the cup be in
Slide and set, so that bar 2 can slide into first position or the second place in the cup, to realize the passage 21 and the pipeline
3 connections；Or said inner tube 6 is connected with the pipeline 3.When the passage 21 is connected with the pipeline 3, pipe can be passed through
Road 3 and liquid injecting mouth 5 are vacuumized to container, at the same time, fluid injection can be carried out in the fluid injection chamber 13, so that when saving work
Between, improve fluid injection efficiency., in turn can be with due to being vacuum state in container when said inner tube 6 is connected with the pipeline 3
Fluid injection is drawn into the purpose that fluid injection is realized in container, whole injection process by inner tube 6, contiguous block 4, pipeline 3 and liquid injecting mouth 5
Using siphon principle, fluid injection is very thorough, so as to avoid raffinate in liquid injection port water clock.
Above disclosed is only the preferred embodiments of the present invention, can not limit the right model of the present invention with this certainly
Enclose, therefore the equivalent variations made according to scope of the present invention patent, still fall within the scope that the present invention is covered.
