The ink replenishment container is detachably mounted on the image forming apparatus, such as: the printer, after the image forming apparatus is connected with the ink replenishment container, the ink replenishment container can supply the image forming apparatus with ink. When the image forming apparatus prints, the developing medium in the ink replenishment container is ejected onto a recording medium (such as paper, or other recording medium that can carry the developing medium).

One or more ink replenishment containers may be installed in the image forming apparatus. For example, the imaging device may be equipped with four ink replenishment containers containing different colors (e.g., cyan, magenta, yellow, and black) of ink. Further, the ink replenishment container mounted on the image forming apparatus may be one, two, three, five or more.

In the present embodiment, as shown in fig. 6, the diameter of the upper engaging portion 23 is larger than the inner diameter of the opening 12, so that the upper engaging portion 23 can abut against the upper end surface of the joint portion 13, ensuring that the seal 2 is fixed at the opening 12.

Preferably, the diameter of the upper engaging portion 23 is equal to the outer diameter of the engaging portion 13, so that the upper engaging portion 23 is attractive while abutting against the upper end surface of the engaging portion 13.

Preferably, the diameter of the upper engaging portion 23 is larger than the outer diameter of the engaging portion 13, so that the upper engaging portion 23 cannot pass through the inner diameter of the engaging portion 13 by elastic deformation when the sealing member 2 is mounted at the opening 12, improving the reliability of the connection of the sealing member 2 with the body member 1.

In a specific embodiment, as shown in fig. 6, an end of the lower engaging portion 24 away from the upper engaging portion 23 is provided with a first guiding slope, and the thickness of the lower engaging portion 24 gradually decreases in a direction away from the axis of the seal 2.

In this embodiment, as shown in fig. 6, the first guiding inclined surface may guide the lower engaging portion 24 to deform uniformly during the installation of the seal member 2, so as to facilitate the axial uniform movement of the seal member 2 to be embedded inside the cylindrical engaging portion 13.

Specifically, the surface of the lower engaging portion 24 that abuts against the engaging portion 13 is a stopper surface that can prevent the seal 2 from coming out of the opening 12. The stop surface is disposed perpendicular to the axis of the seal 2 such that the lower engagement portion 24 is generally snap-fit. The stop surface helps to prevent the seal 2 from separating from the body member 1 when the ink supply needle is separated from the seal 2.

In a specific embodiment, as shown in fig. 7, the connection portion includes an upper engaging portion 23 and at least one annular protrusion 29, the body member 1 is provided with the engagement portion 13, the upper engaging portion 23 can abut against an upper end surface of the engagement portion 13, and the annular protrusion 29 can abut against an inner wall of the engagement portion 13.

In the present embodiment, as shown in fig. 7, the outer diameter of the annular projection 29 is larger than the inner diameter of the opening 12, and when the seal 2 is mounted to the opening 12, the annular projection 29 abuts against the inner wall of the joint 13, and the annular projection 29 is interference-fitted with the inner wall of the joint 13, thereby ensuring the sealing effect of the seal 2 to the opening 12. At the same time, the upper engaging portion 23 abuts against the upper end surface of the joint portion 13, and the sealing effect of the seal 2 on the opening 12 is further improved.

Specifically, one, two or more annular projections 29 may be provided on the body 22.

In a specific embodiment, as shown in fig. 5 and 6, a sealing portion 26 is connected to the inner wall of the body 22, and a bottom wall of the sealing portion 26 is provided with a cutout for opening or closing the liquid flow passage 21.

In the present embodiment, as shown in fig. 5 and 6, the sealing portion 26 is connected to the inner wall of the body 22, so that the liquid flow path 21 can be sealed, and ink leakage during storage or transportation of the ink replenishment container can be prevented. The ink supply needle of the image forming apparatus can extend into the liquid flow path 21 through the slit, and the ink in the accommodating chamber 11 can flow into the ink supply needle, thereby realizing the ink supply of the ink replenishment container to the image forming apparatus.

Specifically, the incision may be cross-shaped or "#" shaped. The slit is closed and the sealing portion 26 seals the liquid flow path when the ink replenishment container is transported or stored; when the ink supply needle is inserted into the notch, the sealing part is attached to the ink supply needle to prevent the ink replenishing container from leaking ink during ink supply.

In a specific embodiment, as shown in fig. 5 and 6, the side wall of the sealing portion 26 is provided with a support rib 27, and the support rib 27 is located on the side of the cutout away from the connecting portion in the axial direction of the body 22.

In this embodiment, as shown in fig. 5, the supporting ribs 27 are arc-shaped protrusions provided on the inner wall of the sealing member 2, and a pressure relief opening 28 is formed between the two supporting ribs 27, so that after the supporting ribs 27 are abutted against the ink supply needle, the sealing portion 26 and the ink supply needle form a sealing space, and when the ink supply needle opens the slit, the pressure in the slit is inconsistent with the pressure outside the slit, causing the ink to jet and pollute the outside.

In addition, the support ribs 27 may be provided in three, four, five, or the like. The support rib 27 is provided with a second guide slope capable of guiding an ink supply needle of the image forming apparatus to be inserted into the liquid flow path 21 through a cutout of the seal portion 26. Specifically, two support ribs 27 are arranged in an array on the inner wall of the body 22 along the circumferential direction of the body 22, so that the second guiding inclined surfaces of the two support ribs 27 are located on the same conical surface, namely, an annular protruding structure arranged on the inner wall of the sealing member 2 is split into two sections with equal length.

The embodiment of the present utility model also provides an ink replenishment container, as shown in fig. 8 and 9, which further includes a bottle cap 3, the bottle cap 3 being detachably connectable to the body member 1.

In the present embodiment, as shown in fig. 8 and 9, when storing or transporting the ink replenishment container, the bottle cap 3 can be closed to the end of the body member 1 near the opening 11, so that the sealing member 2 is accommodated in the bottle cap 3, thereby preventing the sealing member 2 from being separated from the body member 1 by an external force, and protecting the opening 12 of the body member 1 and the sealing member 2.

Specifically, as shown in fig. 9, an external thread may be disposed on the bottle body 1, and an internal thread may be disposed on the bottle cap 3, where the external thread is matched with the internal thread, so as to realize detachable connection between the bottle cap 3 and the bottle body 1. The cap 3 can also be connected to the body 1 by other means of connection.

Further, a protrusion adapted to the sealing portion 26 may be provided on the inner side of the bottle cap 3, so that when the bottle cap 3 is covered on the bottle body 1, the protrusion extends into the sealing portion 26 and abuts against the inner wall of the sealing portion 26, so as to limit the shape of the sealing portion 26 and reduce the probability of leaking ink from the ink replenishing container through the notch, thereby further sealing the sealing portion 26 by the protrusion.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
