[0031] As Figure 1 shown, this embodiment provides an ink cartridge 10 that can be detachably installed on the installation part 20 of a printer. The printer may be an inkjet printer. The printer includes an installation part 20. To better illustrate each component of the installation part 20 and the ink cartridge 10, as Figure 1 a three-dimensional rectangular coordinate system XYZ is established.

[0032] As Figure 1 and Figure 2As shown, the installation part 20 has a box-shaped frame 21, a support member 22, a rotating shaft 23, a liquid introduction part 24, and an engaging mechanism. An insertion port 211 is provided at one end (-Y-axis end) of the frame 21. 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 of moving in the first direction, that is, the ink cartridge moves from the insertion port 211 towards the inner end of the frame 21. If the first direction is represented by the +Y-axis direction, the -Y-axis direction is called the reverse first direction.

[0033] As Figures 1 to 3 shown, the support member 22 extends along a linear guide path 22a. The guide path 22a extends along the first direction (Y-axis direction). The support member 22 has a front end region (-Y-axis end) where the starting end of the guide path 22a is located and a base end region (+Y-axis end) where the terminal end of the guide path 22a is located. The base end region of the support member 22 and the rotating shaft 23 are arranged inside the frame 21 (that is, at a position far from the insertion port 211). The support member 22 includes a receiving groove 223 that cooperates with the ink cartridge. The receiving groove 223 has a groove bottom wall 221 and two groove side walls 222. The two groove side walls 222 are respectively arranged on both sides of the groove bottom wall 221 in the second direction. The second direction is the width direction of the receiving groove 223 and is represented by the X-axis direction. Guide protrusions 226 are provided on both of the two groove side walls 222. The guide protrusions 226 are substantially L-shaped convex rib structures. The guide protrusions 226 extend along the first direction. The reverse first direction end (-Y-axis end) of the guide protrusions 226 bends towards the direction of the groove bottom wall 221, that is, the guide protrusions 226 have a part extending along the third direction. The third direction is perpendicular to the groove bottom wall 222 and away from the ink cartridge, and is represented by the +Z-axis direction in the figure, so the -Z-axis direction is the reverse third direction.

[0034] As Figure 2 and Figure 4 shown, an electrical connection part 224 is provided in the base end region (+Y-axis end) in the receiving groove 223. The electrical connection part 224 is used to engage (electrically connect) with the chip 13 on the ink cartridge 10. The electrical connection part 224 has a certain amount of movement space in the XYZ three directions.

[0035] As Figure 1 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 arranged in 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 arranged in the frame 21 with the rotating shaft 23 as the center. The support member 22 can be in a guiding position ([[]] Figure 1 represented by a single-dot dash line in [[[]]]) where it guides the ink cartridge 10 along the guide path 22a and a connection position ([[]] Figure 1It rotates between (indicated by a double-dot dash line in the Chinese text).

[0036] As Figure 1 shown, the mounting portion 20 may also include a biasing member 25 that biases the support member 22 from the connection position toward the guiding position. The biasing member 25 is, for example, a coil spring. In the initial state where the ink cartridge 10 is not within the mounting portion 20, the support member 22 is disposed at the guiding position by the biasing force of the biasing member 25.

[0037] As Figure 1 and Figure 2 shown, the liquid introduction portion 24 is disposed below the support member 22 (+Z-axis side). When the support member 22 is at the connection position, the liquid introduction portion 24 is connected to the ink cartridge 10. The liquid introduction portion 24 may also be disposed at an inclined attitude with respect to the guiding path 22a. More specifically, the liquid introduction portion 24 may be inclined such that its front end (upper end) is disposed closer to the insertion port 211 in the Y-axis direction than the base end (lower end). For example, the center line of the liquid introduction portion 24 may form an angle within a range greater than 0° and 15° or less with respect to the vertical direction (+Z-axis direction).

[0038] As Figure 3 shown, the engaging mechanism is provided on the side opposite to the first direction (-Y-axis side) of the support member 22. 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 direction opposite to the third direction (-Z-axis direction). In the state where the ink cartridge 10 is installed within the mounting portion 20, at least a part of the ink cartridge 10 is located on the first direction side (+Y-axis side) of the support member. An engaging portion 2821 is provided on the side (+Y-axis side) of the rotating member 282 close to the ink cartridge 10. The engaging portion 2821 is a protruding structure and can engage with the engaged portion 16 (groove structure) on the ink cartridge 10 to restrict the movement of the ink cartridge 10 in the direction opposite to the third direction (-Z-axis direction), thereby fixing the ink cartridge 10 within the mounting portion 20. The rotating member 282 can rotate between an engaging position (a position where the engaging portion 2821 engages with the engaged portion 16) and a disengaged position (a position where the engaging portion 2821 disengages from the engaged portion 16). The rotation axis of the rotating member 282 extends along the X-axis direction. When the support member 22 is at the guiding position, the top surface 2811 (-Z-axis side surface) of the support member 281 is located on the side opposite to the third direction (-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 and has a certain height difference.

[0039] As Figure 4 and Figure 5As shown, the housing of the ink cartridge 10 includes an ink storage member 11 and an adapter 12 installed at the bottom of the ink storage member 11. The ink storage member 11 is generally in the shape of a rectangular parallelepiped box, and the interior of the ink storage member 11 is hollow for storing ink. An ink storage chamber (not shown in the figure) is provided inside the ink storage member 11. The bottom of the ink storage member 11 is detachably provided with an adapter 12 for connecting to the installation part 20 (the adapter 12 can be installed at the bottom of the ink storage member 11 by means of clamping, pasting, welding, etc.). An outlet part 111 is provided at the bottom of the ink storage member 11 and is exposed through a corresponding opening at the bottom of the adapter 12. The outlet part 111 is communicated with the ink storage chamber. When the ink cartridge 10 is installed in place in the installation part 20, the outlet part 111 is communicated with the liquid inlet part 24 and outputs ink to the printer. The outlet part 111 is provided near the -Y axis end of the ink storage member 11. The bottom of the adapter 12 is opened in the area corresponding to the outlet part 111 to avoid the outlet part 111. To ensure the alignment connection between the liquid inlet part 24 and the outlet part 111, an inlet part positioning part 121 is recessed at the bottom of the adapter 12. Both the inlet part positioning part 121 and the outlet part 111 are located at the -Y axis end of the adapter 12, and the inlet part positioning part 121 is farther from the rotation axis 23 than the outlet part 111. An outlet part positioning part 227 is provided on the frame 21 near the liquid inlet part 24. The outlet part positioning part 227 is a convex structure that can be inserted into the inlet part positioning part 121. An assembly groove is provided at the end of the adapter 12 in the first direction, and a chip 13 is installed in the assembly groove.

[0040] As Figures 4 to 6 shown, the housing has oppositely arranged side walls 122 in the second direction (the side walls 122 include the side walls 122 of the ink storage member 11 and the adapter 12 in the second direction). A guiding section 123 for acting on the guiding convex part 226 is recessed at the end of the side wall 122 in the first direction. Preferably, the guiding section 123 is provided at the end of the side wall 122 of the adapter 12 in the first direction. The guiding section 123 is formed by a groove provided on the side wall 122. The guiding section 123 is used to cooperate with the guiding convex part 226 to guide the installation of the ink cartridge 10. When the ink cartridge 10 is installed into the installation part 20, at least part of the guiding convex part 226 is located within the guiding section 123.

[0041] As Figures 4 to 6As shown, the guiding section 123 is provided with a front section 124 at the first direction end (+Y-axis end). The bottom wall (+Z-axis direction end wall) of the front section 124 has guiding inclined surfaces 1241 and connecting surfaces 1242 alternately arranged in the first direction, that is, a number of guiding inclined surfaces 1241 and connecting surfaces 1242 are provided on the bottom wall of the front section 124. 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 guiding inclined surface 1241, the first direction end of the first guiding 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 guiding inclined surface 1241... and they are alternately connected in this order. The reverse first direction end (-Y-axis end) of the guiding inclined surface 1241 is located on the third direction side (+Z-axis side) of the first direction end (+Y-axis end) of the guiding inclined surface 1241, that is, the guiding inclined surface 1241 extends obliquely from the -Y, +Z-axis side to the +Y, -Z-axis side, that is, the first direction end of the guiding inclined surface 1241 is higher than the reverse first direction end, so as to form a sawtooth-like shape on the bottom wall of the front section 124. The connecting surface 1242 is preferably an arc surface. Setting the connecting surface 1242 as an arc surface can make the transition between two guiding inclined surfaces 1241 or between the guiding inclined surface 1241 and other components of the guiding section 123 relatively gentle.

[0042] As Figures 4 to 6 shown, the guiding section 123 is further provided with a rear section 125. The rear section 125 is located on the reverse first direction side (-Y-axis side) of the front section 124. The rear section 125 extends along the first direction. The bottom wall of the rear section 125 is connected to the guiding inclined surface 1241 through the connecting surface 1242, that is, the first direction end of the bottom wall of the rear section 125 is connected to the reverse 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, that is, the connecting surface 1242 is not higher than the bottom wall of the rear section 125.

[0043] Further, as Figure 6As shown, the first direction end (+Y axis end) of the front section 124 has an open section 126, and the open section 126 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 section 125 or is located on the reverse third direction side (+Z axis side) of the top wall of the rear section 125, and 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, +Z axis side to the +Y, -Z axis side, and the first direction end of the upper inclined wall 1261 is higher than the reverse first direction end, and the reverse first direction end of the upper inclined wall 1261 is flush with the top wall of the rear section 125 or higher than the top wall of the rear section 125. The lower inclined wall 1262 extends obliquely from the -Y, -Z axis side to the +Y, +Z axis side, and 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, and the reverse first direction end of the lower inclined wall 1262 is continuous with the guide slope 1241, and the reverse first direction end of the lower inclined wall 1262 is connected to the first direction end of the guide slope 1241 farthest from the rear section 125. The upper inclined wall 1261 is at least partially located on the reverse first direction side of the lower inclined wall 1262, that is, the reverse first direction end of the upper inclined wall 1261 is located on the -Y axis side of the reverse first direction end of the lower inclined wall 1262, and the reverse first direction 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 trumpet-like shape, which is convenient for guiding the protrusion 226 to enter the guide interval 123.

[0044] Furthermore, 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), and the first distance D1>the second distance D2. The open section 126 is set to an asymmetric bell-mouth shape, which can improve the tolerance for the upward tilt of the ink cartridge 10, that is, when the ink cartridge 10 is taken out, the upward tilt of the ink cartridge 10 is large, and it can also be smoothly withdrawn from the installation portion 20.

[0045] like Figure 8As shown, the housing includes a bottom end wall 127. The bottom end wall 127 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 installation part 20, the bottom end wall 127 is located in the accommodation groove 223. A rib portion 128 is provided at the reverse first direction end (-Y-axis end) of the bottom end wall 127. The extending direction of the rib portion 128 intersects the first direction. The rib portion 128 is located around the introduction portion positioning portion 121 and at least partially on the reverse first direction side of the introduction portion positioning portion 121. The rib portion 128 includes a lower end surface 1281 on the third direction side (i.e., the end surface on the +Z-axis side). When the ink cartridge 10 is installed in the accommodation groove 223, the lower end surface 1281 is in contact with the groove bottom wall 221 of the accommodation groove 223.

[0046] As Figure 3 As shown, when the ink cartridge 10 needs to be removed, a force must be applied first to rotate the rotating member 282 from the engaged position to the disengaged position, the engaging portion 2821 is disengaged from the engaged portion 16, and the supporting member 22 is rotated to the guiding position under the action of the applying member 25. Then, the ink cartridge 10 is pulled out in the reverse first direction (-Y-axis direction). However, due to the height difference between the groove bottom wall 221 of the accommodation groove 223 and the top surface 2811 of the support member 281, when the ink cartridge 10 moves in the reverse first direction, the rib portion 128 provided protruding from the bottom end wall 127 of the ink cartridge 10 will interfere with the first direction edge of the support member 281 on the top surface 2811, causing the ink cartridge 10 to jam during the process of disengaging from the installation part.

[0047] As Figure 8 As shown, the ink cartridge 10 further includes an anti-jamming structure 14. The anti-jamming structure 14 is used to prevent the rib portion 128 from interfering with the installation part 20 during the removal of the ink cartridge 10. In this embodiment, the anti-jamming structure 14 includes an inclined side surface 141 connecting the reverse first direction side edge of the lower end surface 1281 of the rib portion 128 and the bottom end wall 127 of the housing. The lower end surface 1281 is located on the first direction side of the inclined side surface 141. The inclined side surface 141 extends obliquely from the -Y, -Z axis sides to the +Y, +Z axis sides. During the process of the ink cartridge 10 being removed in the reverse first direction, the top surface 2811 of the support member 281 contacts the inclined side surface 141 and relatively slides along the inclined side surface 141, causing the reverse first direction end of the ink cartridge 10 to be slightly lifted (along the -Z axis direction) to adapt to the height difference between the lower end surface 1281 of the rib portion 128 and the top surface 2811 of the support member 281, so that the rib portion 128 does not interfere with the support member 281, and the reverse first direction end of the ink cartridge 10 can be more smoothly disengaged from the installation part 20.

[0048] In some other embodiments, such as Figure 9As shown, the anti-jamming structure 14 includes at least two side ribs 142 provided at the reverse first-direction end of the bottom wall 127 of the housing. The at least two side ribs 142 are respectively located on both sides of the rib portion 128 in the second direction. Preferably, two side ribs 142 are provided, and the two side ribs 142 are respectively located at the edge positions of the bottom wall 127 in the second direction. The two side ribs 142 extend in the first direction, and the side ribs 142 have an overlapping portion with the rib portion 128 in the first direction. The third-direction end (+Z-axis end) of the side rib 142 is flush with the lower end surface 1281 or is located on the third-direction side (+Z-axis side) of the lower end surface 1281, that is, the side rib 142 is lower than the lower end surface 1281 of the rib portion 128. When the ink cartridge 10 is installed in the accommodation groove 223, the side rib 142 is in contact with the groove bottom wall 221, that is, the position of the rib portion 128 becomes higher relative to when it directly abuts against the groove bottom wall 221, thereby bridging the height difference between the lower end surface 1281 and the top surface 2811 of the support member 281, so that the rib portion 128 will not interfere with the support portion 281 during the removal process of the ink cartridge 10, and the ink cartridge 10 can smoothly disengage from the installation portion 20. Optionally, the number of the side ribs 142 can also be set to be more, and can be distributed in a certain array on both sides of the rib portion 128 in the second direction, and it is necessary to satisfy having an overlapping portion with the rib portion 128 in the first direction to play the role of lifting the reverse first-direction end of the ink cartridge 10 (especially at the position of the rib portion 128) to bridge the height difference between the lower end surface 1281 of the rib portion 128 and the top surface 2811 of the support member 281.

[0049] In the solution of this embodiment, by setting the bottom wall of the front section 124 of the guiding section 123 into a structure similar to a sawtooth shape (formed by alternately arranging the guiding inclined surface 1241 and the connecting surface 1242), even if the posture of the ink cartridge 10 is slightly upturned during the removal process, the guiding protrusion 226 can smoothly disengage from the guiding section 123 through the guiding of the guiding inclined surface 1241 and the connecting surface 1242, thereby reducing the interference during the removal process of the ink cartridge 10. The anti-jamming structure 14 can bridge the height difference between the lower end surface 1281 of the rib portion 128 and the top surface 2811 of the support member 281, so that the reverse first-direction end of the ink cartridge 10 can also more smoothly disengage from the installation portion 20.

[0050] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
