[0025] See also Figure 1-4The utility model provides a capillary glue feeding head, including a capillary glue feeding head body 100, a conical head 200 is fixed in the middle of the bottom surface of the capillary glue feeding head body 100, a glue discharge port 201 is opened on the outer wall of the conical head 200, the glue discharge port 201 passes through the conical head 200, a connecting hole 202 is opened in the middle of the bottom surface of the inner wall of the glue discharge port 201, a glue feeding port 300 is opened at the inclined end of the capillary glue feeding head body 100, a first inner hole 301 is opened on the inner wall of the connecting hole 202, and the first inner hole 301 is connected with the glue feeding port 300.

[0026] Further Figure 3 As shown, a glue outlet 400 is formed on a side of the outer wall of the capillary glue feeder body 100 , a second inner hole 401 is formed on the inner wall of the first inner hole 301 , and the second inner hole 401 is connected to the glue outlet 400 .

[0027] By setting the glue outlet 400 and the second inner hole 401, when the sealing plunger 501 blocks the connecting hole 202, after the liquid chain polymer gel is injected into the glue inlet 300 by the high-pressure pump, the glue in the first inner hole 301 can be pushed by the injected glue, so that the glue in the first inner hole 301 can be discharged from the glue outlet 400, thereby achieving glue discharge.

[0028] Further Figure 3 As shown, a top hole 500 is opened in the middle of the top surface of the capillary glue feeding head body 100, and the top hole 500 is communicated with the glue discharge port 201. A sealing plunger 501 is movably engaged in the top hole 500.

[0029] The connecting hole 202 can be closed and opened by the provided sealing plunger 501 , so that glue can be injected into the capillary through the glue discharge port 201 and the glue in the first inner hole 301 can be discharged.

[0030] This solution has the following working process: by integrating the conical head 200 with the capillary tube glue feeder body 100, the structure of the entire capillary tube glue feeder body 100 is simple and easy to use.

[0031] By changing the length of the first inner hole 301 to a straight line, the current path is greatly shortened, thereby reducing the voltage provided by the power supply. At the same time, it avoids the situation when using a traditional curved inner hole, where the current passes through the curved inner hole, causing the curved part to be easily affected by the current and burn out, thereby affecting the normal electrophoresis.

[0032] According to the above working process, it can be known that when injecting glue into the capillary, the sealing plunger 501 is pressed downward, the bottom of the sealing plunger 501 blocks the top of the connecting hole 202, the capillary is connected to the glue outlet 400, and the tail end of the capillary is placed in the cathode buffer solution, and then the input end of the high-pressure pump is placed in a container storing liquid chain polymer gel, and the output end of the high-pressure pump is connected to the glue inlet 300, and the high-pressure pump is started. The high-pressure pump injects the liquid chain polymer gel in the container into the connecting hole 202 and the first inner hole 301, so that the connecting hole 202 and the first inner hole 301 are filled with liquid chain polymer gel, and then the liquid chain polymer gel enters the capillary through the second inner hole 401 and the glue outlet 400, until the capillary is completely filled with liquid chain polymer gel, thereby realizing the injection of glue into the capillary.

[0033] During electrophoresis, the sealing plunger 501 is pulled upward to separate the bottom of the sealing plunger 501 from the top of the connecting hole 202. The conical head 200 is then placed in the anode buffer solution. The positive and negative electrodes of the capillary electrophoresis instrument are respectively connected to the top of the positive electrode body 601 and the gel inlet 300. The capillary electrophoresis instrument is started, and the current enters the anode buffer solution in the gel outlet 201 from the positive electrode body 601, and then reaches the cathode buffer solution through the connecting hole 202, the first inner hole 301, the second inner hole 401, the gel outlet 400 and the chain polymer gel of the liquid in the capillary, thereby achieving electrophoresis.

[0034] Further as Figure 3 As shown, a positive electrode fixing hole 600 is opened on one side of the top surface of the capillary injection head body 100 . The positive electrode fixing hole 600 passes through the conical head 200 . A positive electrode body 601 is fixed in the positive electrode fixing hole 600 .

[0035] By setting the positive electrode fixing hole 600, the position of the positive electrode body 601 can be fixed. By setting the positive electrode, during electrophoresis, the current can enter the anode buffer through the positive electrode, and then reach the capillary position connected to the gel outlet 400 through the connecting hole 202, the first inner hole 301 and the gel in the second inner hole 401, and then reach the cathode buffer at the tail end of the capillary to achieve electrophoresis.

[0036] Further Figure 3 As shown, a screw hole 700 is opened on one side of the top surface of the capillary glue feeding head body 100, and a fastening screw 701 is connected in the screw hole 700.

[0037] The capillary glue feeder body 100 can be fixed on the machine by means of the set fastening screws 701.

[0038] In summary: when injecting glue into the capillary, press the sealing plunger 501 downward, the bottom of the sealing plunger 501 blocks the top of the connecting hole 202, connect the capillary to the glue outlet 400, and place the tail end of the capillary in the cathode buffer solution, then place the input end of the high-pressure pump in the container storing the liquid chain polymer gel, connect the output end of the high-pressure pump to the glue inlet 300, start the high-pressure pump, and inject the liquid chain polymer gel in the container into the connecting hole 202 and the first inner hole 301, so that the connecting hole 202 and the first inner hole 301 are filled with the liquid chain polymer gel, and then the liquid chain polymer gel enters the capillary through the second inner hole 401 and the glue outlet 400, until the capillary is completely filled with the liquid chain polymer gel, thereby realizing the injection of glue into the capillary.

[0039] During electrophoresis, the sealing plunger 501 is pulled upward to separate the bottom of the sealing plunger 501 from the top of the connecting hole 202. The conical head 200 is then placed in the anode buffer solution. The positive and negative electrodes of the capillary electrophoresis instrument are respectively connected to the top of the positive electrode body 601 and the gel inlet 300. The capillary electrophoresis instrument is started, and the current enters the anode buffer solution in the gel outlet 201 from the positive electrode body 601, and then reaches the cathode buffer solution through the connecting hole 202, the first inner hole 301, the second inner hole 401, the gel outlet 400 and the chain polymer gel of the liquid in the capillary, thereby achieving electrophoresis.

[0040] The capillary colloid feeder body 100, the positive electrode body 601 and the fastening screw 701 can be purchased on the market, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
