[0041] The sealing plug 5 is integrally formed, and two grooves 51 are symmetrically provided on the top surface of the sealing plug 5. The function of the grooves 51 is to contain a small amount of ink overflowing from the print head when the ink cartridge is taken out, thereby solving the problem that this small amount of ink affects the appearance of the ink cartridge and even pollutes the user.

[0042] The bottom of the groove 51 is provided with a circular countersunk hole 511 matching the printer, and the center spacing of the circular countersunk hole 511 is consistent with the spacing of the two nozzles of the printer. The portion 1.0-1.5MM below the bottom of the circular countersunk hole 511 is set as a sealing layer 52, which is a complete sealing layer without a punching cut to ensure that the product does not leak ink during transportation. After the product enters the machine, the ink suction needle of the print head pierces the sealing layer 52. The bottom of the sealing plug 5 extends downward to form two blind tubes 541 and 542, which correspond to the two circular countersunk holes 511 respectively. The top surface of the blind tubes 541 and 542 is the bottom surface of the sealing layer 5. The lower ends of the blind tubes 541 and 542 are open and extend into the ink bottle 4. After the sealing layer 52 is pierced, the upper end of the blind tube communicates with the circular countersunk hole 511, and the blind tube becomes a through tube.

According to the installation direction of the bottle cap 2, a sink portion 21 is provided in the upper part of the bottle cap 2, that is, in the position of the bottle cap 2 closer to the top of the bottle cap 2. The sink portion 21 divides the inner cavity of the bottle cap 2 into two parts, upper and lower. The sink portion 21 is provided with two circular holes 22, which are coaxial with the two countersunk holes 511 of the sealing plug 5, and the circular hole 22 is provided with an inclined inlet at the entrance of the installation direction. The bottom of the outer wall of the bottle cap 2 is provided with an annular shoulder 23 protruding outward. After the bottle cap 2 is welded to the ink bottle 4, the annular shoulder 23 is pressed by the ink bottle cap 1. The bottom surface of the bottle cap 2 is provided with an ultrasonic welding line 24, which is specifically located directly below the force-bearing circumferential wall of the bottle cap 2. Preferably, the cross section of the ultrasonic welding line 24 is an isosceles triangle. The inner wall of the bottle mouth cover 2 is provided with a plurality of vertical inner grooves 25 at intervals, and the inner grooves 25 cooperate with the strip-shaped positioning protrusions 532 of the sealing plug 5 for positioning.

When the chip seat 3 is installed into the ink bottle cap 1 through the installation window 123, the elastic deformation part 31 shrinks and deforms. After the chip seat 3 is installed into the ink bottle cap 1, the elastic deformation part 31 returns to its original position and presses against the inner wall of the ink bottle cap 1, so that the chip seat 3 is fixed. The chip seat 3 has an anti-reverse installation design: one side of the chip seat 3 is intact without an opening, and the other side is provided with an opening 32. The convex rib 13 of the ink bottle cap 1 matches the chip seat 3. When the chip seat 3 is correctly installed in place, the convex rib 13 extends into the opening of the chip seat 3, otherwise the chip seat 3 cannot be installed. When the chip seat 3 needs to be removed from the ink bottle cap 1, the elastic deformation parts 31 on both sides are shrunk and deformed by external force, and the chip seat 3 is taken out, and then the chip seat and / or the chip in the chip seat 3 are replaced or other operations are performed.

[0054] The assembly process of the inkjet cartridge of this embodiment includes the following steps:
