Description

Technical Field

[0001] The utility model relates to the technical field of conductive paste filling, in particular to a conductive paste filling device. Background Art

[0002] At present, the conductive paste is mostly injected by using a syringe to absorb the conductive paste, and then injecting it into the electrode cap with a flat metal needle. The front end of the metal needle is a straight tube needle, and the resistance is large when squeezing out the conductive paste, making it difficult to squeeze out. Since the conductive paste contains a large amount of chloride ions, it is easy to cause corrosion and blockage of the metal needle, which is inconvenient to use. The flat metal needle is not conducive to separating the hair, and there is a risk of scratching the scalp when using it.

[0003] In view of this, we propose a conductive paste injection device. Utility Model Content

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0025] Embodiment 1: A conductive paste injection device, see Figures 1 to 3 , including a syringe barrel 1, and also including a needle 2; the needle 2 is arranged at the barrel head end of the syringe barrel 1; the conductive paste can be pre-filled in the syringe barrel 1, and the needle 2 and the syringe barrel 1 can form a sealed storage to prevent the moisture of the conductive paste from volatilizing;

[0026] The needle 2 includes a fixed male head 21; the fixed male head 21 is screwed together with the fixed female head 11 at the head end of the syringe barrel 1; the installation is tight and effectively sealed; wherein the needle 2 is conical in design from the tail end to the front end to reduce the extrusion resistance during injection.

[0027] The utility model provides a needle 2 with a conical design, which reduces the resistance of the glue injection operation during glue injection and provides a better operating experience, and solves the problem that the front end of the metal needle is a straight tube, which causes great resistance when squeezing out the conductive paste and is difficult to extrude.

[0028] Specifically, two holding positions 22 are symmetrically provided on the outer wall of the outer end of the needle 2 , and the two holding positions 22 are protruding outwards, so as to facilitate the spiral installation of the needle 2 and the barrel end of the syringe barrel 1 .

[0029] Furthermore, the outlet end of the needle 2 is designed to be breakable and pried apart. After being pried apart, two forked pins 24 are provided at the front end of the needle 2. The outer ends of the forked pins 24 are designed as spherical balls, which are convenient for separating hair and treating the scalp, and are easy to operate.

[0030] Furthermore, the outlet end of the needle 2 is plugged with a return plug 23, and the bifurcated pins 24 at the outlet end of the needle 2 are plugged into the bifurcated opening of the return plug 23. The return plug 23 can be inserted into the outlet end of the needle 2 to close the two bifurcated pins 24 to form a sealed seal, so as to seal and store the unused conductive paste, prevent the conductive paste from volatilizing, and facilitate secondary glue filling.

[0031] It is worth noting that the needle 2 is made of plastic material, which avoids corrosion by conductive paste, is not easy to clog the needle 2, is convenient for mass processing, reduces processing costs, can be used once, and avoids cross interference.

[0032] Working principle: When using the device of the utility model, the conductive paste is pre-filled in the syringe barrel 1. When in use, unplug the return plug 23, hold the syringe barrel 1, touch the scalp with the ball end of the syringe barrel 1, separate the hair, push the push rod of the syringe barrel 1 to inject the conductive paste, and the conductive paste is discharged along the tapered needle 2 with little resistance. When not in use, the return plug 23 can be inserted into the outlet end of the needle 2 to close the two bifurcated pins 24 to form a sealed seal, so as to seal and store the unused conductive paste.
