Description

Technical field

[0001] The utility model relates to a reusable ink replenisher. [Background Technology]

[0002] Currently, ink printers on the market require ink cartridges to provide them with ink for printing, and users need to refill the cartridges regularly. Currently, there are no dedicated ink refill devices for ink cartridges on the market. Conventional methods of refilling ink are syringes, but these are difficult to store and the needle tip is long and easily broken, so they are usually discarded after a single use. This is environmentally unfriendly and has high refill costs.

[0003] Therefore, it is necessary to make further improvements. [Utility Model Content]

[0004] The purpose of the present invention is to overcome the above problems. We provide a reusable ink refill that can be reused and has the function of protecting the ink filling head.

[0005] To achieve the above-mentioned purpose, we provide a reusable ink replenisher, which includes an ink storage container, a piston head and a protective shell. The front end of the ink storage container is provided with an ink filling head and the rear end is provided with an ink filling port. The rear end of the ink storage container is connected to a sealing cover for closing the ink filling port. The piston head is arranged inside the ink storage container, and the piston head has an operating rod extending from the sealing cover. The protective shell is sleeved on the front end of the ink storage container and can slide back and forth relative to the ink storage container. The front end surface of the protective shell is provided with an avoidance opening corresponding to the ink filling head, and a spring is arranged between the protective shell and the ink storage container.

[0006] In one or more embodiments, the outer side wall of the ink storage container is provided with an anti-slip protrusion, and the shell wall of the protective shell is provided with a matching sliding groove at a position corresponding to the anti-slip protrusion.

[0007] In one or more embodiments, a guiding slope is provided on the edge of the rear end opening of the protective shell.

[0008] In one or more embodiments, the inner side of the protective shell is provided with a plurality of circumferentially distributed clips for fixing the spring, one end of the spring is clamped into the clip, and the other end of the spring is abutted against the front end surface of the ink storage container.

[0009] In one or more embodiments, the sealing cap is threadably connected to the ink storage container.

[0010] In one or more embodiments, the piston head includes a main body and a plurality of sealing rings sleeved on the outer circumference of the main body, wherein the plurality of sealing rings are distributed at intervals, and the sealing rings abut against the inner wall of the ink storage container.

[0011] In one or more embodiments, the ink storage container is a cylindrical transparent ink storage container.

[0012] Compared with the prior art, the present invention has the following technical effects: the ink refill can be reused multiple times and can be disassembled and cleaned. When idle, the ink refill head can be protected by a protective shell to prevent it from breaking, which is convenient to use and reduces the cost of ink refilling.

Brief Description of the Drawings

[0013] Figure 1 This is a schematic structural diagram of an ink refill device according to an embodiment of the present invention;

[0014] Figure 2 This is a schematic diagram of an embodiment of the utility model in which the protective shell is moved back to reveal the ink filling head. [Specific implementation method]

[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0016] Please see Figure 1-2 The present application provides a reusable ink refiller, which includes an ink storage container 1, a piston head and a protective shell 3. The front end of the ink storage container is provided with an ink filling head 4 and the rear end is provided with an ink filling port. The rear end of the ink storage container 1 is connected to a sealing cover 5 for closing the ink filling port. The user can fill the ink storage container with ink by opening the sealing cover. The piston head is arranged inside the ink storage container, and the piston head has an operating rod 6 extending from the sealing cover. The operating rod can facilitate the user to push and pull the piston head. The protective shell 3 is sleeved on the front end of the ink storage container and can slide back and forth relative to the ink storage container. The front end surface of the protective shell 3 is provided with an avoidance opening 7 corresponding to the ink filling head. A spring 8 is provided between the protective shell and the ink storage container. By pushing the protective shell backward, the ink filling head is exposed and then inserted into the ink filling port of the corresponding ink cartridge, and then the operating rod is pushed to refill the ink cartridge with ink; in addition, the avoidance opening 7 can be aligned with the ink filling port on the ink cartridge first, and then the ink storage container is pushed hard, and the protective shell can also slide backward by itself, so that the ink filling head is inserted into the ink filling port.

[0017] The outer wall of the ink container 1 is provided with an anti-slip protrusion 9. The protective shell wall has a matching slot 10 at the position corresponding to the anti-slip protrusion. The two ends of the matching slot represent the sliding travel of the protective shell. The anti-slip protrusion prevents the protective shell from falling off the ink container when not in use. A guiding slope 11 is provided on the edge of the rear opening of the protective shell 3. The guiding slope facilitates the anti-slip protrusion to slightly deform the protective shell during installation, until it contacts the matching slot, completing the installation.

[0018] The inner side of the protective shell 3 is provided with a plurality of circumferentially distributed clamps 12 for fixing the spring. One end of the spring is inserted into the clamp, and the other end of the spring is abutted against the front end face of the ink storage container 1. Preferably, 3 or 4 clamps are provided. Under the positioning effect of the clamp, problems such as twisting, deformation, and displacement when the spring is stretched or compressed can be avoided.

[0019] In order to facilitate users to remove or install the sealing cover, the sealing cover 5 is threadedly connected to the ink storage container 1. Specifically, an external thread structure is provided on the outer wall of the rear end of the ink storage container, and a matching internal thread structure is provided on the inner wall of the sealing cover.

[0020] The piston head 2 includes a main body and multiple sealing rings 13 sleeved on the outer circumference of the main body 2. The multiple sealing rings are distributed at intervals and abut against the inner wall of the ink storage container. The provision of multiple sealing rings can prevent ink from overflowing from the rear of the ink storage container when the piston head is pushed, thereby strengthening the sealing effect.

[0021] In order to facilitate the user to observe the color of the ink and remind the user to refill the ink, the ink storage container 1 is a cylindrical transparent ink storage container.

[0022] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the content disclosed in the present invention should be included in the protection scope recorded in the claims.
