In the embodiment of the present application, the number of the limiting grooves 226 is three, and an included angle between any two limiting grooves 226 is 120 °.

When the ink supply device 100 needs to be replenished with ink, the ink bottle 200 needs to be mounted on the ink supply device 100, in an initial state, the sliding protrusion 242 is located in the first sliding groove 2371, at this time, the end of the main body portion 241 far away from the limiting portion 243 abuts against the blocking piece 250 and seals the third channel 251, and the ink in the bottle body 210 cannot flow out from the third channel 251; the user rotates the first connecting member 220 and/or the bottle body 210 in a counterclockwise direction, the first connecting member 220 can drive the movable member 240 to rotate in the counterclockwise direction, and the sliding protrusion 242 moves along the second sliding groove 2372 in a direction approaching the third sliding groove 2373, so that the main body portion 241 moves in a direction approaching the bottle body 210; when the sliding protrusion 242 moves into the third sliding groove 2373, the end of the main body 241 away from the position-limiting portion 243 is separated from the blocking member 250 and opens the third channel 251, and the ink in the bottle 210 can flow out from the third channel 251, so that the second channel 233 can be opened.

When the ink is completely replenished into the ink supply device 100, the ink bottle 200 needs to be detached from the ink supply device 100, the user rotates the first connecting member 220 and/or the bottle body 210 in the clockwise direction, the first connecting member 220 can drive the movable member 240 to rotate in the clockwise direction, and the sliding protrusion 242 moves along the second sliding groove 2372 in the direction close to the first sliding groove 2371, so that the main body portion 241 moves in the direction away from the bottle body 210; when the sliding protrusion 242 moves into the first sliding groove 2371, the end of the main body portion 241 away from the limiting portion 243 contacts the blocking member 250 and closes the third channel 251, and the ink in the bottle 210 cannot flow out from the third channel 251, so that the second channel 233 is closed.

Before removing the ink bottle 200 from the ink supply device 100, the user may rotate the bottle body 210 and/or the second connector 230 in a clockwise direction to close the second channel 233, and then remove the ink bottle 200. At this time, the ink inflow portion 130 is pulled out from the second channel 233, so that the problem of ink leakage does not occur, and further, the ink leakage is prevented from contaminating the printing apparatus and the surrounding environment.

In some embodiments, the guiding portion may also be a sliding protrusion extending radially from an inner wall of the ink outflow portion, and the guided portion may also be a guiding groove opening on a side wall of the movable member 240 along a rotation direction of the movable member 240, and at least a portion of the sliding protrusion may be received in the guiding groove.

Specifically, the guiding portion may be a sliding protrusion 242 extending from an inner wall of the second connecting member 230 in a radial direction, and the guided portion may be a guiding groove 237 opened on a side wall of the main body portion 241 in a rotation direction of the movable member 240, that is, the sliding protrusion 242 may be disposed on the inner wall of the second connecting member 230, and the guiding groove 237 may be disposed on the side wall of the main body portion 241.

During assembly, the position-limiting portion 243 of the movable member 240 is first installed in the position-limiting groove 226 of the first connecting member 220; then at least part of the second connecting piece 230 is arranged in the installation groove 224 in the first connecting piece 220, and the limit protrusion 225 on the first connecting piece 220 is arranged in the annular groove 236 of the second connecting piece 230, so that the movable piece 240 is arranged between the first channel 223 and the second channel 233; then, the blocking member 250 is fitted into the second passage 233 from the ink outlet port 234; finally, when ink needs to be replenished into the ink supply device 100, the ink bottle 200 is inverted and the second connector 230 is installed in the slot 150, the ink inflow portion 130 is inserted into the second channel 233 from the third channel 251, and the second channel 233 is opened and closed by rotating the bottle body 210 and/or the first connector 220.

Compared with the prior art, in the ink bottle 200 provided by the utility model, when the ink bottle 200 is installed in the image forming apparatus, because the movable element 240 can rotate along with the rotation of the bottle body 210, and the inner wall of the ink outflow part is provided with at least one guide part, the movable element 240 is correspondingly provided with at least one guided part, and the guided part can move along the guide part in the rotation process of the movable element 240, so that the main body part 241 moves towards the direction close to or away from the bottle body 210 to open or close the outflow channel, therefore, a user can open or close the outflow channel by rotating the bottle body 210, before the ink bottle 200 is detached from the image forming apparatus, the user can rotate the bottle body 210 to close the outflow channel first and then detach the ink bottle 200, thereby solving the problem that the ink leakage occurs due to poor sealing performance after the ink supply needle is pulled out in the existing ink bottle 200, thereby preventing ink leakage from polluting printing equipment and the surrounding environment.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
