As shown in Fig. 2, the liquid injecting mouth 5 is plugged in the liquid injection port of battery case before fluid injection, so that liquid injecting mouth 5 and electricity
The connection of pond enclosure interior；Bar 2 is moved down by the pressure of vaccum-pumping equipment and compresses the spring 7 in the cup, so that institute
It states plug 22 to be inserted into 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
It is connected to the link block 4；Meanwhile the outlet in the channel 21 of bar 2 is connected to the connector 41 of the link block 4 in the cup,
It is connected to realize with the pipeline 3.At this point, the battery case, liquid injecting mouth 5, pipeline 3, link block 4 and channel 21 form one
Access, the vaccum-pumping equipment vacuumize battery case 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, the vaccum-pumping equipment removes, so that the pressure of bar 2 disappears in the cup when completing to vacuumize
It loses, 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 be made to leave institute
The outlet of the upper end of inner tube 6 is stated, the link block 4 is left in the outlet in the channel 21, at this point, the channel 21 and link block 4
Access partition, and said inner tube 6, link block 4, pipeline 3 and liquid injecting mouth 5 form an access.In the vacuum of the battery case
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 case, realize fluid injection.
Compared with prior art, since the present invention is by the way that said inner tube 6 to be connected to link block 4, and by the pipeline 3
One end is connected to the link block 4, and the other end is connected to the liquid injecting mouth 5, then bar 2 in one glass is arranged, and makes the bar 2 in the cup be in
Sliding setting, to enable bar 2 in the cup to slide into first position or the second position, to realize the channel 21 and the pipeline
3 connections；Or it is connected to said inner tube 6 with the pipeline 3.When the channel 21 is connected to the pipeline 3, pipe can be passed through
Road 3 and liquid injecting mouth 5 vacuumize container, at the same time, fluid injection can be carried out in the fluid injection chamber 13, thus when saving work
Between, improve fluid injection efficiency.It, in turn can be with due to being vacuum state in container when said inner tube 6 is connected to the pipeline 3
Fluid injection is drawn into the purpose that fluid injection is realized in container, entire injection process by inner tube 6, link block 4, pipeline 3 and liquid injecting mouth 5
Using siphon principle, fluid injection is very thorough, to avoid raffinate in liquid injection port water clock.
The above disclosure is only a preferred example of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore according to equivalent variations made by scope of the present invention patent, still falls within the range that the present invention is covered.
