Description

[0001] This application is a divisional application of the patent application filed on July 30, 2024, with application number 2024218250636 and utility model title "An Ink Cartridge". Technical Field

[0002] This utility model relates to the field of printing consumables technology, and in particular to an ink cartridge. Background Technology

[0003] The installation and removal of a certain type of original ink cartridge involves a translational operation, specifically insertion and withdrawal along opposite linear directions. To ensure proper alignment of the cartridge during insertion, the printer mounting section features a pair of L-shaped ridges acting on both sides of the cartridge. The original ink cartridge has grooves on the outer wall of its receiving cavity along the insertion direction that guide the alignment of these ridges. In some cases, when the user removes the cartridge, part of the ridges remains within the grooves. The user must maintain a horizontal position for removal. Slight upward tilting of the cartridge can cause interference between the lower end of the ridges and the grooves, making the removal process less smooth. Utility Model Content

[0004] According to one aspect of the present invention, an ink cartridge is provided, which can be inserted into a support member of a mounting portion of a printer along a linear first direction. The support member has a receiving groove that mates with the ink cartridge. The receiving groove has a bottom wall and side walls located on both sides of the bottom wall in a second direction. The mounting portion further includes a guide portion positioning portion and a support member, the support member being located on the side of the guide portion positioning portion opposite to the first direction. The ink cartridge includes:

[0005] The housing has side walls disposed opposite each other in a second direction and a bottom wall on a third direction side. The bottom wall is provided with an inlet positioning part that cooperates with the outlet positioning part at the end opposite to the first direction. The bottom wall is also provided with a protruding rib at the end opposite to the first direction. The extending directions of the protruding rib intersect the first direction. The protruding rib is at least partially located on the side opposite to the inlet positioning part in the first direction.

[0006] An anti-jamming structure is provided to prevent interference between the protruding rib and the support component during the removal of the ink cartridge. The anti-jamming structure is at least partially located on the opposite side of the positioning part of the inlet portion.

[0007] The second direction is orthogonal to the first direction, and the third direction is perpendicular to the bottom wall of the slot and away from the ink cartridge.

[0008] In some embodiments, the rib includes a lower end face located on a third direction side, and the anti-jamming structure includes an oblique side face connecting the lower end face's edge in the opposite first direction to the bottom wall, the lower end face being located on the first direction side of the oblique side face.

[0009] In some embodiments, during the removal of the ink cartridge in the opposite direction, the support component of the mounting portion contacts the inclined side and slides relative to the inclined side, thereby lifting the end of the ink cartridge in the opposite direction.

[0010] In some embodiments, the anti-jamming structure includes at least two side support ribs disposed on the bottom end wall in the opposite first direction. The at least two side support ribs are respectively located on both sides of the convex rib in the second direction. The side support ribs have overlapping portions with the convex rib in the first direction. The third direction end of the side support rib is flush with or located on the third direction side of the lower end face of the convex rib on the third direction side.

[0011] In some embodiments, the side support ribs are located at the edge of the bottom end wall in a second direction.

[0012] In some embodiments, when the ink cartridge is installed in the receiving slot, the side support ribs fit against the bottom wall of the slot, raising the reverse first direction end of the ink cartridge to bridge the height difference between the lower end face and the top surface of the reverse third direction side of the support component.

[0013] In some embodiments, the groove sidewall is provided with a guide protrusion, the sidewall is recessed at the first direction end to provide a guide interval acting on the guide protrusion, and the guide interval is provided with a front section at the first direction end;

[0014] The bottom wall of the front section has guide slopes and connecting surfaces alternately arranged in a first direction, and the reverse first direction end of the guide slope is located on the third direction side of the first direction end of the guide slope.

[0015] In some embodiments, the guide section is further provided with a rear section, which is located on the opposite side of the front section in the first direction. The rear section extends along the first direction, and the bottom wall of the rear section is connected to the guide slope through a connecting surface.

[0016] In some embodiments, the first directional end of the front section has an open section, the open section including an upper inclined wall, the reverse first directional end of the upper inclined wall being flush with or located on the reverse third directional side of the top wall of the rear section, and the first directional end of the upper inclined wall being located on the reverse third directional side of the reverse first directional end of the upper inclined wall.

[0017] In some embodiments, the open section further includes a lower inclined wall, the first directional end of which is located on the third directional side of the bottom wall of the rear section, and the reverse first directional end of which is connected to the guide slope.

[0018] The beneficial effects of this utility model are as follows: This solution provides a guiding slope and a connecting surface on the bottom wall of the front section of the guiding interval. Even if the ink cartridge tilts slightly upwards during removal, the guiding protrusion can smoothly detach from the guiding interval through the guiding slope and connecting surface, thereby reducing interference during ink cartridge removal and allowing the ink cartridge to detach smoothly from the mounting part. The anti-jamming structure prevents interference between the protruding rib and the mounting part, allowing the reverse-direction end of the ink cartridge to detach from the mounting part more smoothly as well.

[0033] like Figure 1 As shown, this embodiment provides an ink cartridge 10 that can be detachably installed into the mounting part 20 of a printer. The printer can be an inkjet printer, and the printer includes the mounting part 20. To better explain the mounting part 20 and the various components of the ink cartridge 10, as follows... Figure 1 Establish a three-dimensional rectangular coordinate system XYZ.

[0034] like Figure 1 and Figure 2 As shown, the mounting part 20 has a box-shaped frame 21, a support member 22, a rotating shaft 23, a liquid inlet 24, and a locking mechanism. One end (-Y axis end) of the frame 21 is provided with an insertion port 211. The ink cartridge 10 is inserted into the frame 21 through the insertion port 211. The installation process of the ink cartridge 10 includes a translation operation that moves along a first direction, that is, the ink cartridge moves from the insertion port 211 toward the inner end of the frame 21. The first direction is represented by the +Y axis direction, and the -Y axis direction is called the reverse first direction.

[0035] like Figures 1 to 3 As shown, the support member 22 extends along a straight guide path 22a. The guide path 22a extends along a first direction (Y-axis direction). The support member 22 has a front end region (-Y-axis end) where the beginning of the guide path 22a is located and a base end region (+Y-axis end) where the end of the guide path 22a is located. The base end region of the support member 22 and the rotation shaft 23 are disposed on the inside of the frame 21 (i.e., away from the insertion port 211). The support member 22 includes a receiving groove 223 that mates with the ink cartridge. The receiving groove 223 has a bottom wall 221 and two side walls 222, which are respectively disposed on both sides of the bottom wall 221 in a second direction, which is the width direction of the receiving groove 223, denoted by the X-axis direction. Both slot sidewalls 222 are provided with guide protrusions 226. The guide protrusions 226 are roughly L-shaped convex ridge structures. The guide protrusions 226 extend along the first direction. The end of the guide protrusions 226 opposite to the first direction (-Y axis end) bends toward the bottom wall 221 of the slot. That is, the guide protrusions 226 have a part extending along a third direction. The third direction is the direction perpendicular to the bottom wall 222 of the slot and away from the ink cartridge. In the figure, the third direction is represented by the +Z axis direction, and the -Z axis direction is the opposite third direction.

[0036] like Figure 2 and Figure 4 As shown, an electrical connection portion 224 is provided in the base region (+Y axis end) of the receiving slot 223. The electrical connection portion 224 is used to engage (electrically connect) with the chip 13 on the ink cartridge 10. The electrical connection portion 224 has a certain amount of room to move in the XYZ directions.

[0037] like Figure 1As shown, the rotating shaft 23 has an axis that intersects both the vertical direction (+Z-axis direction) and the guide path 22a (Y-axis direction) and is disposed at the base end region (+Y-axis end) of the support member 22. The axis of the rotating shaft 23 extends along the X-axis direction. The support member 22 is rotatably disposed within the frame 21 about the rotating shaft 23, and the support member 22 can guide the ink cartridge 10 to the guide position along the guide path 22a (…). Figure 1 The connection point between the ink cartridge 10 and the liquid inlet section 24 (represented by a single-dot dash) is shown in the image. Figure 1 Rotation between (represented by double-dotted lines in the middle).

[0038] like Figure 1 As shown, the mounting portion 20 may also include a force-applying member 25 that applies force to the support member 22 from the connection position toward the guide position. The force-applying member 25 is, for example, a coil spring. In the initial state where the ink cartridge 10 is not in the mounting portion 20, the support member 22 is positioned in the guide position by the force applied by the force-applying member 25.

[0039] like Figure 1 and Figure 2 As shown, the liquid inlet 24 is positioned below the support member 22 (on the +Z axis side). When the support member 22 is in the connected position, the liquid inlet 24 is connected to the ink cartridge 10. The liquid inlet 24 can also be configured in an inclined position relative to the guide path 22a. More specifically, the liquid inlet 24 can also be configured with its front end (upper end) positioned closer to the insertion port 211 in the Y-axis direction than its base end (lower end). For example, the centerline of the liquid inlet 24 can form an angle greater than 0° and less than 15° relative to the vertical direction (+Z axis direction).

[0040] like Figure 3As shown, the engaging mechanism is located on the side of the support member 22 opposite to the first direction (-Y axis side). The engaging mechanism includes a support member 281 fixed to the frame 21 and a rotating member 282 hinged to the support member 281. The engaging mechanism is used to restrict the movement of the ink cartridge 10 in the opposite third direction (-Z axis direction). When the ink cartridge 10 is installed in the mounting part 20, the ink cartridge 10 is at least partially located on the first direction side (+Y axis direction side) of the support member. The rotating member 282 has an engaging part 2821 on the side (+Y axis side) near the ink cartridge 10. The engaging part 2821 is a protruding structure that can engage with the engaging part 16 (groove structure) on the ink cartridge 10 to restrict the movement of the ink cartridge 10 in the opposite third direction (-Z axis direction) and fix the ink cartridge 10 in the mounting part 20. The rotating member 282 is capable of rotating between an engaged position (the position where the engaging part 2821 is engaged with the engaged part 16) and a disengaged position (the position where the engaging part 2821 is disengaged from the engaged part 16), and the axis of rotation of the rotating member 282 extends along the X-axis direction. When the support member 22 is in the guide position, the top surface 2811 (the surface on the -Z-axis side) of the support member 281 is located on the opposite third direction side (the -Z-axis side) of the bottom wall 221 of the receiving groove 223, that is, the top surface 2811 of the support member 281 is higher than the bottom wall 221 of the groove, and there is a certain height difference.

[0041] like Figure 4 and Figure 5 As shown, the ink cartridge 10 housing includes an ink storage component 11 and an adapter 12 mounted on the bottom of the ink storage component 11. The ink storage component 11 is generally rectangular box-shaped and hollow inside for storing ink. The ink storage component 11 has an ink storage cavity (not shown in the figure). The bottom of the ink storage component 11 is detachably provided with the adapter 12 for connecting with the mounting part 20 (the adapter 12 can be installed on the bottom of the ink storage component 11 by snapping, pasting, welding, etc.). The bottom of the ink storage component 11 is provided with an outlet 111 exposed from the corresponding opening at the bottom of the adapter 12. The outlet 111 communicates with the ink storage cavity. When the ink cartridge 10 is installed in the mounting part 20, the outlet 111 communicates with the liquid inlet part 24 and outputs ink to the printer. The outlet 111 is located near the -Y axis end of the ink storage component 11. The bottom of the adapter 12 has an opening in the area corresponding to the outlet 111 to avoid the outlet 111. To ensure proper alignment between the liquid inlet 24 and the outlet 111, an inlet positioning part 121 is recessed at the bottom of the adapter 12. Both the inlet positioning part 121 and the outlet 111 are located at the -Y axis end of the adapter 12, and the inlet positioning part 121 is further away from the rotation axis 23 than the outlet 111. An outlet positioning part 227 is provided on the frame 21 near the liquid inlet 24. The outlet positioning part 227 is a protruding structure into which the inlet positioning part 121 can be inserted. The adapter 12 has an assembly groove at its end in the first direction, and a chip 13 is installed in the assembly groove.

[0042] like Figures 4 to 6 As shown, the housing has a sidewall 122 disposed opposite to the ink reservoir 11 and the adapter 12 in the second direction. The sidewall 122 has a guide section 123 that acts on the guide protrusion 226 recessed at the first direction end. Preferably, the guide section 123 is disposed on the first direction end of the sidewall 122 of the adapter 12. The guide section 123 is formed by a groove disposed on the sidewall 122. The guide section 123 is used to cooperate with the guide protrusion 226 to guide the ink cartridge 10 to be installed. When the ink cartridge 10 is installed in the mounting part 20, the guide protrusion 226 is at least partially located in the guide section 123.

[0043] like Figures 4 to 6 As shown, the guide section 123 has a front section 124 at the first direction end (+Y axis end). The bottom wall of the front section 124 (the end wall in the +Z axis direction) has guide inclined surfaces 1241 and connecting surfaces 1242 alternately arranged in the first direction. That is, the bottom wall of the front section 124 has a number of guide inclined surfaces 1241 and connecting surfaces 1242. Along the first direction (+Y axis direction), the first direction end of the first connecting surface 1242 is connected to the reverse first direction end of the first guide inclined surface 1241, the first direction end of the first guide inclined surface 1241 is connected to the reverse first direction end of the second connecting surface 1242, the first direction end of the second connecting surface 1242 is connected to the reverse first direction end of the second guide inclined surface 1241, and so on, alternately connected in this order. The reverse first direction end (-Y axis end) of the guide slope 1241 is located on the third third direction side (+Z axis side) of the first direction end (+Y axis end) of the guide slope 1241. That is, the guide slope 1241 extends obliquely from the -Y and +Z axis sides to the +Y and -Z axis sides. In other words, the first direction end of the guide slope 1241 is higher than the reverse first direction end, thereby forming a sawtooth-like shape on the bottom wall of the front section 124. The connecting surface 1242 is preferably an arc-shaped surface. Setting the connecting surface 1242 as an arc-shaped surface can make the transition between the two guide slopes 1241 or between the guide slope 1241 and other components of the guide section 123 smoother.

[0044] like Figures 4 to 6 As shown, the guide section 123 also includes a rear section 125, which is located on the opposite side (-Y axis side) of the front section 124. The rear section 125 extends along the first direction, and its bottom wall is connected to the guide inclined surface 1241 via a connecting surface 1242. That is, the first direction end of the bottom wall of the rear section 125 is connected to the opposite first direction end of the first connecting surface 1242. The connecting surface 1242 is located on the third direction side (+Z axis side) of the rear section 125, meaning that the connecting surface 1242 is not higher than the bottom wall of the rear section 125.

[0045] Furthermore, such as Figure 6As shown, the first direction end (+Y axis end) of the front segment 124 has an open section 126, which includes an upper inclined wall 1261 and a lower inclined wall 1262. The reverse first direction end of the upper inclined wall 1261 is flush with the top wall of the rear segment 125 or located on the reverse third direction side (-Z axis side) of the top wall of the rear segment 125. The first direction end (+Y axis end) of the upper inclined wall 1261 is located on the reverse third direction side (-Z axis side) of the reverse first direction end (-Y axis end) of the upper inclined wall 1261. The upper inclined wall 1261 extends obliquely from the -Y and +Z axis sides to the +Y and -Z axis sides. The first direction end of the upper inclined wall 1261 is higher than the reverse first direction end. The reverse first direction end of the upper inclined wall 1261 is flush with or higher than the top wall of the rear segment 125. The lower inclined wall 1262 extends obliquely from the -Y and -Z axis sides to the +Y and +Z axis sides. The first direction end of the lower inclined wall 1262 is located on the third direction side (+Z axis side) of the bottom wall of the rear section 125, that is, the first direction end of the lower inclined wall 1262 is lower than the bottom wall of the rear section 125. The reverse first direction end of the lower inclined wall 1262 is connected to the guide inclined surface 1241. The reverse first direction end of the lower inclined wall 1262 is connected to the first direction end of the guide inclined surface 1241 that is farthest from the rear section 125. The upper inclined wall 1261 is at least partially located on the opposite side of the lower inclined wall 1262 in the first direction, that is, the opposite end of the upper inclined wall 1261 is located on the -Y axis side of the opposite end of the lower inclined wall 1262 in the first direction. The opposite end of the upper inclined wall 1261 is roughly aligned with the middle position of the guide inclined surface 1241 connected to the lower inclined wall 1262. The upper inclined wall 1261 and the lower inclined wall 1262 together form a shape similar to a trumpet mouth, which facilitates the guide protrusion 226 to enter the guide interval 123.

[0046] Furthermore, such as Figure 7 As shown, in the third direction, the distance between the first direction end of the upper inclined wall 1261 and the rear section 125 is the first distance D1 (the distance between the first direction end of the upper inclined wall 1261 and the top wall of the rear section 125), and the distance between the first direction end of the lower inclined wall 1262 and the rear section 125 is the second distance D2 (the distance between the first direction end of the lower inclined wall 1262 and the bottom wall of the rear section 125), with the first distance D1 > the second distance D2. Setting the open section 126 into an asymmetrical flared shape can improve the tolerance for the upward tilt of the ink cartridge 10, that is, when the ink cartridge 10 is removed, even if the upward tilt of the ink cartridge 10 is large, it can still be smoothly ejected from the mounting part 20.

[0047] like Figure 8As shown, the housing includes a bottom wall 127, which refers to the end wall of the adapter 12 on the third direction side (+Z axis side). When the ink cartridge 10 is installed in the mounting part 20, the bottom wall 127 is located in the receiving groove 223. The bottom wall 127 is provided with a protruding rib 128 at the end opposite to the first direction (-Y axis end). The extending direction of the protruding rib 128 intersects the first direction. The protruding rib 128 is located around the inlet positioning part 121 and is at least partially located on the side opposite to the first direction of the inlet positioning part 121. The protruding rib 128 includes a lower end face 1281 (i.e., the end face on the +Z axis side) located on the third direction side. When the ink cartridge 10 is installed in the receiving groove 223, the lower end face 1281 is in contact with the bottom wall 221 of the receiving groove 223.

[0048] like Figure 3 As shown, when it is necessary to remove the ink cartridge 10, force must first be applied to rotate the rotating member 282 from the engaged position to the disengaged position, so that the engaged part 2821 disengages from the engaged part 16. The supporting member 22 rotates to the guiding position under the action of the force-applying member 25, and then the ink cartridge 10 is pulled out along the reverse first direction (-Y axis direction). However, since there is a height difference between the bottom wall 221 of the receiving groove 223 and the top surface 2811 of the support member 281, when the ink cartridge 10 moves along the reverse first direction, the protruding rib 128 provided on the bottom end wall 127 of the ink cartridge 10 will interfere with the support member 281 at the first direction edge of the top surface 2811, causing the ink cartridge 10 to get stuck during the process of disengaging from the mounting part.

[0049] like Figure 8 As shown, the ink cartridge 10 also includes an anti-jamming structure 14, which is used to prevent interference between the protruding rib 128 and the mounting portion 20 during the removal of the ink cartridge 10. In this embodiment, the anti-jamming structure 14 includes a sloped side 141 connecting the lower end face 1281 of the protruding rib 128 on the side opposite to the first direction and the bottom wall 127 of the housing. The lower end face 1281 is located on the first direction side of the sloped side 141, and the sloped side 141 extends obliquely from the -Y, -Z axis side to the +Y, +Z axis side. During the removal of the ink cartridge 10 in the reverse first direction, the top surface 2811 of the support component 281 contacts the inclined side surface 141 and slides relative to each other along the inclined side surface 141, so that the reverse first direction end of the ink cartridge 10 is slightly raised (along the -Z axis direction) to accommodate the height difference between the lower end surface 1281 of the convex rib 128 and the top surface 2811 of the support component 281, so that the convex rib 128 will not interfere with the support component 281, and the reverse first direction end of the ink cartridge 10 can be more smoothly removed from the mounting part 20.

[0050] In some other implementations, such as Figure 9As shown, the anti-jamming structure 14 includes at least two side support ribs 142 disposed on the bottom end wall 127 of the housing in the opposite direction. The at least two side support ribs 142 are respectively located on both sides of the protruding rib portion 128 in the second direction. Preferably, there are two side support ribs 142, with the two side support ribs 142 respectively located at the edge position of the bottom end wall 127 in the second direction. The two side support ribs 142 extend along the first direction, and the side support ribs 142 have an overlapping portion with the protruding rib portion 128 in the first direction. The third direction end (+Z axis end) of the side support rib 142 is flush with or located on the lower end surface 1281. On the third directional side (+Z axis side) of the lower end face 1281, that is, the side support rib 142 is lower than the lower end face 1281 of the convex rib 128. When the ink cartridge 10 is installed in the receiving groove 223, the side support rib 142 fits against the bottom wall 221 of the groove. That is, the position of the convex rib 128 becomes higher than when it directly abuts against the bottom wall 221 of the groove, thereby bridging the height difference between the lower end face 1281 and the top surface 2811 of the support component 281. This ensures that the convex rib 128 will not interfere with the support component 281 during the removal of the ink cartridge 10, and the ink cartridge 10 can be smoothly removed from the mounting part 20. Alternatively, the number of side support ribs 142 can be increased, and they can be distributed in a certain array on both sides of the convex rib 128 in the second direction. They must also overlap with the convex rib 128 in the first direction in order to raise the end of the ink cartridge 10 in the opposite first direction (especially at the position of the convex rib 128) to bridge the height difference between the lower end surface 1281 of the convex rib 128 and the top surface 2811 of the support component 281.

[0051] In this embodiment, by setting the bottom wall of the front section 124 of the guide interval 123 into a sawtooth-like structure (the guide slope 1241 and the connecting surface 1242 are alternately arranged), even if the ink cartridge 10 is slightly tilted upwards during removal, the guide protrusion 226 can smoothly detach from the guide interval 123 through the guidance of the guide slope 1241 and the connecting surface 1242, thereby reducing interference during the removal of the ink cartridge 10. The anti-jamming structure 14 can bridge the height difference between the lower end surface 1281 of the protruding rib 128 and the top surface 2811 of the support component 281, so that the reverse first direction end of the ink cartridge 10 can also detach from the mounting part 20 more smoothly.

[0052] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
