[0026] [Ink Cartridge Installation Department]

[0027] Figure 1 This is a perspective view of the ink cartridge mounting part involved in this utility model; Figure 2 It is along Figure 1 Plan view after sectioning along the AA direction.

[0028] like Figure 1 and Figure 2As shown, the ink cartridge mounting part 110 includes a housing 101 and an ink-absorbing needle 102. The housing 101 is box-shaped and has an internal space. The internal space is provided with mounting slots for mounting ink cartridges. Specifically, the housing 110 has multiple mounting slots, and different mounting slots can be used to mount ink cartridges 30 that contain different colors of ink. The direction intersecting the front-back direction is the left-right direction, and the multiple mounting slots are arranged along the left-right direction. The direction intersecting both the left-right direction and the front-back direction is the up-down direction. Preferably, the front-back direction, the left-right direction, and the up-down direction are arranged along the left-right direction. The vertical direction is mutually orthogonal; the internal space of the housing 101 is provided with three partitions 109, which are arranged at intervals in the left and right direction. The internal space of the housing 101 forms four mounting slots 108A, 108B, 108C and 108D in the left and right direction. Mounting slot 108A is located on the leftmost side of the four mounting slots, mounting slot 108B is located on the right side of mounting slot 108A, mounting slot 108C is located on the right side of mounting slot 108B, and mounting slot 108D is located on the right side of mounting slot 108C and is located on the rightmost side of the four mounting slots.

[0029] The ink-absorbing needle 102 is located in the internal space of each mounting slot 108A, 108B, 108C and 108D. The ink-absorbing needle 102 is a hollow cylindrical tube and is used to draw ink contained in the ink cartridge 30. The ink-absorbing needle 102 extends from the ink tank (not shown in the figure) into the internal space of each mounting slot 108A, 108B, 108C and 108D in the front-back direction, and the rear end of the ink-absorbing needle 102 is open.

[0030] The housing 101 has a clearance space 162 below the ink needle 102. The ink cartridge mounting part 110 is also provided with an ink receiver 130 located in the clearance space 162. Each mounting slot is provided with an ink receiver 130. The ink receiver 130 has a front end portion 131 and a rear end portion 132 arranged opposite to each other in the front-back direction.

[0031] The ink receiver 130 is movable between a first position and a second position. In the first position, the ink receiver 130 is close to the ink suction needle 102, and in the second position, the ink receiver 130 is away from the ink suction needle 102. Compared with the first position, the ink receiver 130 is further away from the ink suction needle 102 in the second position. Specifically, in the first position, the ink receiver 130 is held with its rear end portion 132 close to the ink suction needle 102. At this time, the space formed between the ink receiver 130 and the ink suction needle 102 in the vertical direction does not allow the lower part of the ink outlet 33 to enter. The ink receiver 130 is held in the first position by a retainer (not shown). In some embodiments, the retainer is set as an elastic member.

[0032] When the ink receiver 130 moves downward from the first position to the second position against the force applied by the retainer, the ink receiver 130 is held in a state where the rear end portion 132 is away from the ink suction needle 102. At this time, the space formed between the ink receiver 130 and the ink suction needle 102 in the vertical direction allows the lower part of the ink outlet 33 to enter, and the ink outlet 33 can then engage with the ink suction needle 102. Meanwhile, during the installation of the ink cartridge 30, the ink receiver 130 does not restrict the forward movement of the ink cartridge 30.

[0033] In some implementations, the rear end portion 132 may also contact the ink-absorbing needle 102 in the first position.

[0038] Figure 6 The ink cartridge involved in this utility model, after being installed into the ink cartridge mounting part, along... Figure 1 Plan view after sectioning along the AA direction.

[0039] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the ink cartridge 30 also includes a pusher 80 detachably connected to the container body 31. During the installation of the ink cartridge 30, the pusher 80 is used to abut against the rear end portion 132 of the ink receiver 130, forcing the rear end portion 132 of the ink receiver 130 to move downward. The ink receiver 130 moves from the first position to the second position, and the lower part of the ink outlet 33 can enter the space between the rear end portion 132 and the ink suction needle 102. At the same time, the ink suction needle 102 is connected to the ink outlet 33 through the ink outlet 34.

[0040] The pusher 80 includes a pusher body 81 and a pusher portion 83 disposed on the pusher body 81. The pusher body 81 is detachably mounted on the container body 31.

[0041] In some embodiments, the pusher 80 / pusher body 81 is detachably mounted to the container housing 45, and in some specific embodiments, at least a portion of the pusher 80 is located below the ink outlet 33 in the vertical direction.

[0042] In some embodiments, the pusher 80 / pusher body 81 is sleeved on the ink outlet 33 / ink outlet body 35. In this case, the pusher 80 includes a mounting cavity 82 and a fixing part 84 formed at the front end of the mounting cavity 82. The mounting cavity 82 is formed inside the pusher body 81 and extends in the front-rear direction. This facilitates the sleeve of the pusher body 81 on the ink outlet body 35 in the front-to-back direction. The radial dimension of the mounting cavity 82 is greater than or equal to the radial dimension of the ink outlet 34. The fixing part 84 is used to allow the ink needle 102 to pass through. The fixing part 84 is configured as an annular shape with a through hole. The through hole communicates with the mounting cavity 82, and the radial dimension of the through hole is less than or equal to the radial dimension of the ink outlet 34. In the front-to-back direction, at least a portion of the ink outlet 34 coincides with the through hole.

[0043] In some embodiments, the pusher 80 may not have a fixing part 84.

[0044] The pusher 83 is used to push the rear end portion 132 of the ink receiver 130. The rear end portion 132 is provided with a forced pusher 132a for abutting against the pusher 83. The forced pusher 132a is provided with a forced pusher surface 132a1 that is inclined relative to the front-back direction. During the installation of the ink cartridge 30, the pusher 83 abuts against the forced pusher surface 132a1.

[0045] In some embodiments, the pushing part 83 is provided with a pushing surface 83a that is inclined relative to the front-back direction. When the pushing part 83 pushes the pushing part 132a, the pushing surface 83a abuts against the pushing surface 132a1. In some preferred embodiments, the pushing surface 83a and the pushing surface 132a1 are parallel to each other, that is, the pushing surface 83a and the pushing surface 132a1 are inclined at the same angle relative to the front-back direction.

[0046] In some embodiments, the pushing surface 83a is configured as a curved surface.

[0047] In some embodiments, the pushing part 83 is configured as a protrusion that extends in a direction away from the radial center along the radial direction of the pushing member body 81, the protrusion being used to push the pushing part 132a / pushing surface 132a1.

[0048] In some embodiments, the pushing part 83 is configured as a groove recessed in the radial direction of the pushing part body 81 toward the radial center, and the groove fits into the pushing part 132a. In this way, the pushing part 83 can also push the pushing part 132a during the installation of the ink cartridge 30.

[0049] In some embodiments, the pusher 80 may also be provided with a plurality of pusher sections 83.

[0050] When the ink cartridge 30 is removed from the ink cartridge mounting part 110 in a rearward direction, the pushing member 80 disengages from the rear end part 132 / pushing part 132a of the ink receiver 130, and under the action of the retaining member, the ink receiver 130 moves from the second position to the first position.

[0051] [Beneficial Effects]

[0052] Compared with the prior art, the ink cartridge 30 provided by this utility model has the following beneficial effects:

[0053] Firstly, the ink cartridge 30 is provided with a pushing member 80 for abutting against the ink receiver 130. During the installation of the ink cartridge 30, the pushing member 80 directly abuts against the ink receiver 130, and the ink receiver 130 moves from the first position to the second position. The lower part of the ink outlet 33 of the ink cartridge 30 can enter the space between the ink receiver 130 and the ink suction needle 102, so that the ink suction needle 102 can engage with the ink outlet 33. In other words, while the pushing member 80 forces the ink receiver 130 to avoid, the ink suction needle 102 engages with the ink outlet 33. This operation method is simple and quick, and will not interfere with other components.

[0054] Secondly, as described in the first aspect, during the installation of the ink cartridge 30, the pusher 80 directly abuts against the ink receiver 130, which can improve the operating efficiency of the ink receiver 130.

[0055] Thirdly, the pusher 80 is detachably connected to the container body 31. With this configuration, when the pusher 80 is damaged or cannot be adapted to the container body 31, the pusher 80 can be replaced or repaired in a timely manner, reducing the usage cost of the ink cartridge 30 and avoiding waste.

[0056] Fourthly, the pusher 80 is provided with a pusher 83 for abutting against the pusher 132a. There are no specific restrictions on the shape, number and structure of the pusher 83, which can expand the applicability of the ink cartridge 30.
