As shown in fig. 5 and 8, the present embodiment provides an ink device including an ink tank 2 and an ink replenishment container 1, the ink tank 2 being installed in a printer for storing and supplying ink when the printer is used. After the ink in the ink tank 2 in the printer is used up, in order to avoid difficulty in removing the ink tank 2 and replacing the same, it is generally necessary to supply ink to the ink tank 2 as needed by an independently provided ink supply container 1.

As for the ink replenishment container 1 used for supplying ink to the ink tank 2, as shown in fig. 2 and 6, it includes a container body for storing ink, the container body having an ink outlet passage 121 through which ink passes, and when the ink tank 2 needs to be replenished with ink, the ink flows into the ink tank 2 through the ink outlet passage 121. When the ink is replenished, the ink replenishing container 1 needs to be turned over and then the ink is replenished to the ink tank 2 through the ink outlet channel 121, the ink tank 2 is provided with the ink supply needle 21, when the ink tank 2 is matched with the ink replenishing container 1, the ink supply needle 21 is inserted into the ink outlet channel 121 of the ink replenishing container 1, and the ink is easily ejected to the outside from the ink outlet channel 121 due to the instant release of the pressure inside the ink replenishing container 1 at an instant, so that the ink cannot directly flow into the ink tank 2 to cause the pollution of the external environment; in addition, when the inverted ink refill container 1 is removed after the ink refill is completed, ink remaining at the outlet is likely to remain at the outlet or flow out of the bottle body, thereby causing environmental pollution.

In order to avoid the problem of environmental contamination when the ink replenishment container 1 replenishes the ink tank 2 with ink, the present application provides an ink replenishment container 1, as shown in fig. 2 and 7, including a blocking portion 15, the blocking portion 15 being used to open or block the ink outlet passage 121 so that ink can flow out of the ink outlet passage 121 or restrict the flow out. The blocking portion 15 is provided so as to be opened when ink is replenished to allow ink to flow into the ink tank 2, and the blocking portion 15 is closed to restrict the flow of ink in a non-replenished state, thereby preventing leakage of ink. In order to avoid the situation that the pressure inside the ink replenishing container 1 is increased due to the influence of temperature rise and the like when the ink is replenished, the pressure inside the ink replenishing container 2 is instantaneously released to eject the ink, or after the ink is replenished, the blocking part 15 is closed to cause residual ink to remain at the bottle opening or flow down along the bottle body to cause pollution. Therefore, the closing portion 15 is provided with a vent hole 124 for communicating the inside of the container body with the outside air. Through the vent hole 124, before ink is replenished, no matter the plugging part 15 is in an opening state or a closing state, the vent hole 124 can always communicate the air inside and outside, so that the problem of overlarge pressure caused by internal temperature rise is avoided, and the problem of jetting caused by overlarge pressure during ink replenishing is avoided. Furthermore, the vent hole 124 allows the external air to partially enter through the vent hole 124 when the ink flows out of the ink outlet channel 121, so that the internal ink and air can be better exchanged, and the ink can easily enter the ink tank 2 through the ink outlet channel 121 to the ink supply needle 21, thereby increasing the speed of filling the ink tank 2 with the ink, and facilitating the use. After the ink is replenished, when the ink replenishing container 1 is removed and the blocking portion 15 is closed, residual ink may remain at the outer end of the ink outlet channel 121, and after the ink replenishing container 1 is erected, the residual ink may slowly flow back into the bottle through the vent hole 124, so as to avoid environmental pollution caused by the residual ink.

Here, it should be emphasized that the vent hole 124 is provided so as to have a main function of communicating air between the inside and the outside through the vent hole 124, and therefore, the diameter of the vent hole 124 is small, and in general, it is sufficient that the diameter of the vent hole 124 is smaller than the diameter of the ink supply needle 21, so that it is possible to prevent the ink from flowing out of the vent hole 124 through the excessively large vent hole 124 and affecting the ventilation effect of the vent hole 124. When the residual ink flows back into the bottle through the vent hole 124, the residual ink is less, and the vent hole 124 for venting with small aperture can meet the backflow of the ink, so that the residual ink is prevented from polluting the external environment.

Optionally, in the vent hole 124, in order to avoid that, when the ink tank 2 is replenished with ink, the ink leaks from the vent hole 124 and affects the exchange of air from the vent hole 124 to the inside and the outside, as shown in fig. 3 and 4, the ink replenishing container 1 further includes a seepage-proofing portion 18, and the seepage-proofing portion 18 is provided in the vent hole 124 and is used for limiting the ink from flowing out from the vent hole 124. The impermeable portion 18 may be a sponge, a screen, or other structures capable of preventing ink from flowing out of the vent hole 124, and is not particularly limited herein.

When the blocking portion 15 is a silicone valve to achieve communication or closure of the ink outlet channel 121 by using the above self-sealing valve, failure is likely to occur during use to cause ink leakage, and in order to avoid such a problem, the blocking portion 15 may also be configured as a fitting structure of a valve core, as shown in fig. 2, that is, the blocking portion 15 is movably connected to the ink outlet channel 121, a fitting gap is formed between the blocking portion 15 and the ink outlet channel 121, and the ink outlet channel 121 has a blocking position; the blocking portion 15 moves to the blocking position along the ink outlet passage 121, and the blocking portion 15 blocks the fitting gap. The blocking part 15 is movably connected to the ink outlet channel 121, so that when the ink replenishing container 1 supplies ink to the ink tank 2, the ink supply needle 21 is used for pushing the blocking part 15 to move, so as to push the blocking part 15 to move along the ink channel in the direction away from the blocking position, and the blocking part 15 is enabled to release the blocking of the matching gap, so that the ink can flow into the ink tank 2 through the ink supply needle 21, and meanwhile, the air and liquid exchange function of the vent hole 124 arranged on the blocking part 15 enables the ink to rapidly flow into the ink tank 2 to achieve the purpose of filling the ink. After filling, in the process of removing the ink replenishing container 1, along with the extension of the ink supply needle 21 from the ink outlet channel 121, the blocking part 15 can be reset along with the extension of the ink supply needle 21 under the condition of no thrust of the ink supply needle 21 so as to return to the blocking position again, and the blocking part 15 blocks the matching gap again, so that automatic closing is realized. The original self-sealing valve structure is replaced by the matched blocking part 15, the effect of automatically opening and closing according to requirements can be achieved, meanwhile, the structural stability is good, the problem that leakage is caused due to the fact that self-sealing failure is easy to generate is avoided, and the good effect of filling ink into the ink tank 2 can be achieved.
