Specific embodiment
The application is described in further detail below by specific embodiment and with reference to accompanying drawing.
As Figure 1-3, the embodiment of the present application provides a kind of priming device, and the priming device can be in battery 10
Electrolyte is injected in portion, has electrolyte injecting hole on this battery 10, and priming device is by the electrolyte injecting hole to battery 10
Inside injection electrolyte.This priming device is including fluid injection cup 20, liquid injecting mouth 21, fluid infusion pump 22 and vacuumizes bar 23, wherein：
Fluid injection cup 20 may include cup 200, be installed on cup 200 top cup lid 201 and be installed on cup 200
The cup bottom 202 of bottom, is respectively provided with sealing ring 203 between cup lid 201 and cup bottom 202 and cup 200.Cup 200, the and of cup lid 201
Cup bottom 202 forms electrolyte accommodating chamber after being mounted together, and is opened up on cup lid 201 and vacuumizes hole 201a and fluid infusion hole 201b, takes out
Vacuum hole 201a is used to realize vacuumizing for electrolyte accommodating chamber that fluid infusion hole 201b to be used to realize electrolyte to electrolyte accommodating chamber
Interior fills into operation.

There is liquid injection hole 210, the liquid injection hole 210 is used to import the electrolyte in electrolyte accommodating chamber the inside of battery 10 on 21.
Built with electrolyte, this partial electrolyte liquid can enter in fluid injection cup 20 fluid infusion pump 22 in the presence of fluid infusion pump 22
Electrolyte accommodating chamber in.Specifically, the liquid outlet of fluid infusion pump 22 can be by the fluid infusion hole 201b on cup lid 201 and fluid injection cup
20 electrolyte accommodating chamber is connected, during electrolyte filled into electrolyte accommodating chamber with this.
Vacuumizing the inside of bar 23 has an evacuation passageway 230, and vacuumizes bar 23 and be movably installed on fluid injection cup 20, tool
Body may be mounted on cup lid 201, and through in stretching into electrolyte accommodating chamber after the cup lid 201.Vacuumizing bar 23 can be relative
Moved in fluid injection cup 20, and then be formed close to or away from the shift motion of liquid injecting mouth 21, in the end of the shift motion, take out true
The cup bottom 202 of empty bar 23 and fluid injection cup 20 contacts, and vacuumizes the evacuation passageway of bar 23 and sealed with liquid injection hole 210 and connect.
When realizing the implant operation of electrolyte using above-mentioned priming device, can first drive and vacuumize bar 23 near note
The direction motion of liquid mouth 21, is contacted when bar 23 is vacuumized with cup bottom 202, and evacuation passageway 230 is sealed with liquid injection hole 210 and connected
When logical, it is possible to implement vacuum pumping in the inside to battery 10.At the same time, fluid infusion pump 22 can be operated in fluid injection cup 20
Injection electrolyte.Therefore, carried out while the priming device can realize that fluid infusion is operated in battery vacuum-pumping and fluid injection cup 20, with
This improves the fluid injection efficiency of priming device.
The above-mentioned concrete structure for vacuumizing bar 23 is more various, and in the embodiment of the present application, vacuumizing bar 23 includes body
231st, the elastomeric seal portions 232 of one end of body 231 are arranged at, accordingly, evacuation passageway 230 then includes being opened in body
First passage on 231 and the second channel being opened on elastomeric seal portions 232, first passage are sealed with second channel and connected
Logical, in the end of the shift motion for vacuumizing bar 23, elastomeric seal portions 232 coordinate with the inner wall sealing of fluid injection cup 20.Compare
In vacuumizing, bar 23 is overall by the way of rigid structure, and the elastomeric seal portions 232 in this embodiment have certain elasticity change
Shape ability, after active force is acted on and vacuumized on bar 23, the active force between elastomeric seal portions 232 and cup bottom 202 is bigger,
And then lifting sealing property between the two.
Connected mode between above-mentioned tubular body 231 and elastomeric seal portions 232 is usually and is fixedly connected, and type of attachment can be
The modes not easy to remove such as welding.But, the disassembling operations of bar 23 are vacuumized for simplification, what the embodiment of the present application was provided takes out true
Empty bar 23 can also include attaching nut 233, and the body 231 for vacuumizing bar 23 passes through the attaching nut 233 and elastomeric seal portions
232 are fixedly connected.In addition, during using the connection pipe body 231 of attaching nut 233 and elastomeric seal portions 232, can also be by the company of adjustment
The amount of force that the length of fit of connected nut 233 and body 231 is come between regulation elasticity sealing 232 and body 231, more preferably
Ground ensures to vacuumize the sealing between bar 23 and cup bottom 202.
