The infusion channel 1 of liquid outlet and the inlet, the infusion channel 1 are in frustum cone structure, and the internal diameter of the infusion channel 1
It is sequentially increased along the syringe needle tail portion 2 to 3 direction of syringe needle head.
In the present solution, set frustum cone structure for infusion channel 1, during injecting electrolyte, electrolyte along
Perfusion tube enters in infusion channel 1, since the internal diameter of infusion channel 1 is gradually increased by syringe needle tail portion 2 to syringe needle head 3, so that
The interior space for accommodating electrolyte of infusion channel 1 being gradually increased to 3 direction of syringe needle head along syringe needle tail portion 2, and then slow down needle
The electrolyte in head portion 3 goes out liquid speed degree.It is designed, can be prevented during injecting electrolyte, due to electrolyte by this
It is spent in the liquid speed out of liquid outlet and greatly the battery core of battery is caused to impact, and electrolyte is caused to be splashed to the outside of battery, avoided
The shell of battery is corroded, and improves yield rate, is conducive to optimize production environment, while improving the accuracy of reservoir quantity.In this reality
It applies in example, the spike body is made of aluminum material, and the spike body described in other embodiments can also be using not certainly
Rust steel, copper, glass etc. are made, or using the composite material system of any two or three of formation in al stainless steel, copper, glass
At, or other composite materials is used to be made.In specific implement, syringe needle tail portion 2 and syringe needle head 3 are respectively corresponded
The inner diameter size of infusion channel 1 can be configured according to the actual conditions of battery.
Wherein, rotary table refers to that the plane for being parallel to circular cone bottom surface with one goes to truncated cone, the part between bottom surface and section.
When using the fluid injection syringe needle, perfusion tube set is set to the periphery of the syringe needle tail portion 2, and syringe needle head 3 is gone out liquid
Mouth alignment is arranged in battery liquid-filling mouth, and electrolyte is transported in perfusion tube and enters infusion by the inlet of syringe needle tail portion 2
In channel 1, and then electrolyte is made to pass through the inside that battery liquid-filling mouth enters battery core from the liquid outlet on syringe needle head 3.In this reality
It applies in example, the perfusion tube is sebific duct, but is not restricted to sebific duct, and in other examples, perfusion tube is also possible to steel
Pipe, aluminum pipe etc..Fluid injection syringe needle described in this programme is not limited in injecting electrolyte, can be also used for injecting other liquid,
For example, liquid medicine injection, chemical reagent etc..
The outer diameter of the spike body is gradually reduced along the direction on the syringe needle tail portion 2 to the syringe needle head 3.At present
More typically the shape of spike body is in frustum cone structure, by the outer diameter of spike body by syringe needle tail portion 2 to the side on syringe needle head 3
To being gradually reduced, also guarantee spike body structural strength while the volume of needle body ontology can be reduced as much as possible, guarantees needle
There is head-tail 2 sufficiently large outer diameter to be arranged perfusion tube.It certainly, in other examples, can also be by the spike body
Shape be designed as other structures such as cylindrical structure, prismatic structure.
In this present embodiment, the center at the center of the liquid outlet, the center of the inlet and the infusion channel 1
Axis is on same straight line, and by above-mentioned design, electrolyte is entered by inlet, subsequently into infusion channel 1, is avoided
Electrolyte is detained at inlet and influences the stability of electrolyte injection rate, due to center and the infusion channel 1 of liquid outlet
Central axis is in same straight line, and electrolyte can be projected directly from liquid outlet in infusion channel 1, avoids electrolyte in liquid out
It is detained and influences the stability of electrolyte spray volume at mouthful.
Wherein, the syringe needle tail portion 2 includes being arranged far from the mounting portion 22 of described syringe needle one end and being arranged described
Interconnecting piece 21 between syringe needle head 3 and the mounting portion 22, the mounting portion 22 are connect with the perfusion tube, the mounting portion
22 outer diameter is less than the outer diameter of the interconnecting piece 21, and forms Step-edge Junction between the mounting portion 22 and the interconnecting piece 21
Structure.It is provided with step structure between mounting portion 22 and interconnecting piece 21, facilitates the periphery that perfusion tube is set in mounting portion 22.Institute
Step structure is stated with first while 23 and 23 the second vertical sides 24 when with described first, first side 23 is positioned at being installed
Between portion 22 and the interconnecting piece 21, second side 24 is located on the mounting portion 22, and first side 23 and second
Side 24 connects.Due to first while 23 with second while it is 24 vertical, when 21 grafting of first connecting portion is inserted into perfusion tube, the second side 24
It is abutted with the inside of perfusion tube, the port card on the first side 23 and perfusion tube, and then the first side 23 is prevented to be inserted into perfusion tube
The position-limiting action to perfusion tube is played in inside.It can also be blocked between perfusion tube and mounting portion 22 using the first side 23 simultaneously
Gap prevents electrolyte from revealing between perfusion tube and mounting portion 22.It certainly in other examples, can also be on the first side
23 and second side 24 connect position be arranged lead angle.
As shown in Fig. 2, being convexly equipped with elastic seal ring 5 between the mounting portion 22 and the interconnecting piece 21.It is close by elasticity
Seal 5 can be further ensured that the air-tightness between spike body and perfusion tube, avoid electrolyte from mounting portion 22 and perfusion tube
Junction leakage.
As a preferred technical solution in the present embodiment, as shown in Figures 2 and 3, during fluid injection, usually
Syringe needle head 3 and battery are in non-contacting state, but in practical fluid injection, since manual operation is difficult to avoid that syringe needle head
The generation of 3 the phenomenon that inside battery is deep by battery liquid-filling mouth.In order to make syringe needle head 3 enter electricity by battery liquid-filling mouth
Ensure the smooth fluid injection of fluid injection syringe needle when inside pond, the syringe needle head 3 is recessed at least one far from the end face of the syringe needle tail portion 2
A notch 4.In the case where the liquid outlet in the internal structure plugging pin head portion 3 of battery, electrolyte quilt can ensure that by notch 4
Smoothly it is injected into the inside of battery.In the present embodiment, there are two notches 4 for setting, can also will lack in other examples
Mouth 4 is set as the different quantity such as one, two or three.
It is worth noting that, the shape for notch 4 does not do special limitation, it can be arbitrary shape, such as " U "
Shape, " V " shape etc..
A kind of battery liquid-filling needle is also provided in the present embodiment, including perfusion tube and above-mentioned fluid injection syringe needle.This kind of battery
Injection needle is structurally reasonable, and can alleviate electrolyte goes out liquid speed degree, avoids the spluttering of electrolyte, is easy to use.
