DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0044] In the description of this application, the definition Figure 3 The direction in which the second side surface 202 points to the first side surface 201 is the +X axis direction, the direction in which the fourth side surface 204 points to the third side surface 203 is the +Y axis direction, and the direction in which the bottom surface 205 points to the top surface 206 is the +Z axis direction. The X axis, Y axis and Z axis are perpendicular to each other, and the X axis, Y axis and Z axis are three directions of a three-dimensional rectangular coordinate system.

[0045] In addition, in the description of the present application, if the +X axis side or -X axis side of a component is described, it means that the above-mentioned three-dimensional rectangular coordinate system is established with the center point of the component in the X direction as the coordinate origin, the part located on the +X axis of the coordinate system is called the +X axis side of the component, and the part located on the -X axis of the coordinate system is called the -X axis side of the component. For example, the limiting surface is located on the -X axis side of the extension part, which means that the above-mentioned three-dimensional coordinate system is established with the center point of the extension part in the X direction as the coordinate origin, the +X axis in the coordinate system is called the +X axis side of the extension part, and the -X axis in the coordinate system is called the -X axis side of the extension part. The definitions of the +Y axis side, -Y axis side, +Z axis side or -Z axis side of a component are similar to those of the +X axis side and -X axis side of the component, and are not repeated here.

[0046] Please refer to Figure 1 As shown, in the prior art, the ink cartridge mounting seat 1' comprises a concave hole 11', a rotatable rod 12', a contact needle portion 13' and an ink tube 14', the rotatable rod 12' is provided with a rod hole 121', and the ink cartridge 2' comprises a first clamping position 21', a second clamping position 22', a chip 23' and an ink outlet 24'. When the ink cartridge 2' is mounted on the ink cartridge mounting seat 1', the first clamping position 21' of the ink cartridge 2' is engaged with the concave hole 11' on the ink cartridge mounting seat 1', the second clamping position 22' is engaged with the rod hole 121', the chip 23' is in contact with the contact needle portion 13', and the ink outlet 24' matches with the ink tube 14'. The ink outlet 24' is arranged on the bottom surface 201' of the ink cartridge 2', the surface opposite to the bottom surface 201' is the top surface 202', the direction from the bottom surface 201' to the top surface 202' is the +Z axis direction in the figure, and the direction from the first clamping position 21' to the second clamping position 22' is the +X axis direction in the figure.

[0047] However, the prior art solution will result in that after the ink cartridge 2' is installed on the ink cartridge mounting seat 1', the ink cartridge 2' is subjected to the force F1 given by the ink tube 14', the ink cartridge 2' is subjected to the force F2 given by the stylus portion 13', and the ink cartridge 2' is subjected to the force F3 given by the rod hole 121'. The second clamping position 22' of the ink cartridge 2' gives the rotatable rod 12' a reaction force F3' opposite to the force F3. If the forces F1 and F2 are large, the reaction force F3' will also be large. When the reaction force F3' is too large, the rotatable rod 12' will rotate in the +X axis direction, and the second clamping position 22' will be separated from the rod hole 121', thereby causing the ink cartridge 2' to be separated from the ink cartridge mounting seat 1'.

[0048] Please also refer to Figure 2 , Figure 3 and Figure 6 As shown, an embodiment of the present application discloses an ink cartridge 2, which can be detachably mounted on an ink cartridge mounting seat 1. The ink cartridge mounting seat 1 includes a mounting seat body 11 and a movable member 12, the mounting seat body 11 has an opening in the +Z axis direction, the movable member 12 is rotatably connected to the mounting seat body 11, and the movable member 12 has a joint 121 and a limiting portion 122. The ink cartridge 2 includes an ink cartridge body 21 and a snap-fit ​​mechanism 22, the ink cartridge body 21 is used to store ink, the snap-fit ​​mechanism 22 is movably arranged on the ink cartridge body 21, and the snap-fit ​​mechanism 22 includes a limiting member 222 and a snap-fit ​​portion 223. When the ink cartridge 2 is mounted on the ink cartridge mounting seat 1, the snap-fit ​​portion 223 cooperates with the joint 121 to limit the movement of the ink cartridge 2 in the +Z axis direction, and the limiting member 222 cooperates with the limiting portion 122 to limit the positional relationship between the movable member 12 and the snap-fit ​​mechanism 22, thereby preventing the ink cartridge 2 from being separated from the ink cartridge mounting seat 1.

[0049] For details, please refer to Figure 5 and Figure 7 As shown, the joint portion 121 is provided with a limiting groove 121a, and the engaging portion 223 includes at least two positioning members 223a, each positioning member 223a is distributed along the Y-axis direction, and at least a part of the positioning member 223a is in the -X-axis direction of the limiting member 222. When the ink cartridge 2 is installed on the ink cartridge mounting seat 1, the positioning member 223a extends into the limiting groove 121a, and the positioning member 223a cooperates with the limiting groove 121a to prevent the positioning member 223a from moving in the +Z-axis direction, that is, to prevent the ink cartridge 2 from moving in the +Z-axis direction; when the ink cartridge 2 is installed on the ink cartridge mounting seat 1, the limiting member 222 abuts against the limiting portion 122, limiting the positional relationship between the limiting member 222 and the limiting portion 122 in the X-axis direction, and preventing the limiting portion 122 from moving in the +X-axis direction. That is, the movable member 12 is prevented from rotating when subjected to a force in the +Z-axis direction, thereby preventing the ink cartridge 2 from detaching from the ink cartridge mounting seat 1.

[0050] Please continue to refer to Figure 3 , Figure 4As shown, the ink cartridge 2 also includes a positioning column 23 and a chip 24. The ink cartridge body 21 is a box structure that is approximately a rectangular parallelepiped, and includes a first side 201, a second side 202, a third side 203, a fourth side 204, a bottom surface 205, a top surface 206 and an inclined surface 207. The first side 201 and the second side 202 are arranged oppositely, the third side 203 and the fourth side 204 are arranged oppositely, the top surface 206 and the bottom surface 205 are arranged oppositely, and the inclined surface 207 is arranged between the first side 201 and the bottom surface 205. The first side 201 is provided with a mounting hole 211, and the third side 203 and the fourth side 204 are respectively provided with a limiting hole 212, and the limiting hole 212 extends along the X-axis direction. Preferably, the limiting hole 212 is a through hole in the Y-axis direction. The bottom surface 205 is provided with an ink outlet 25, and the ink in the ink cartridge body 21 can be provided to the printing device through the ink outlet 25. The positioning post 23 is disposed on the second side surface 202, and the chip 24 is disposed on the inclined surface 207. The chip 24 is disposed on the inclined surface 207, and the ink outlet 25 and the chip 24 are not disposed on the same plane, which reduces the possibility of the chip 24 being contaminated by the ink leaked from the ink outlet 25.

[0051] Please continue to refer to Figure 4 and Figure 5 As shown, the engaging mechanism 22 also includes a main body 221, a limiting protrusion 224, an abutting portion 225 and an elastic member 226, wherein the limiting member 222, the positioning member 223a, the limiting protrusion 224 and the abutting portion 225 are respectively arranged on the main body 221, and the main body 221, the limiting member 222, the positioning member 223a, the limiting protrusion 224 and the abutting portion 225 are integrally formed. The limiting protrusion 224 is arranged corresponding to the limiting hole 212. During assembly, the elastic member 226 and the main body 221 are respectively installed in the mounting hole 211, one end of the elastic member 226 is connected to the inner wall of the mounting hole 211, and the other end of the elastic member 226 is connected to the main body 221. The limiting protrusion 224 is located in the limiting hole 212, and the limiting protrusion 224 can move in the limiting hole 212 along the X-axis direction, that is, the engaging mechanism 22 can move in the mounting hole 211 along the X-axis direction. In other embodiments, the main body 221 is further provided with a protrusion extending in the X-axis direction, and the mounting hole 211 is provided with a groove extending in the X-axis direction, so that the main body 221 can move more smoothly in the X-axis direction. In another embodiment, the main body 221 can also be provided with some recesses to cooperate with the protrusions provided on the mounting hole 211, so that the engaging mechanism 22 is fixed on the ink cartridge 2, and the main body 221 can move on the ink cartridge 2 in the X-axis direction.

[0052] Specifically, the positioning member 223a has a joint surface 223b, which is the surface where the positioning member 223a contacts the limiting groove 121a, and the number of the joint surfaces 223b is consistent with the number of the positioning members 223a. The limiting member 222 is a hook-shaped structure, roughly in the shape of "ㄇ", and includes a main body 222a and an extension 222b. The main body 222a is in the shape of "┏", and one end of the main body 222a is connected to the main body 221, and the other end of the main body 222a is connected to the extension 222b. The extension 222b extends along the Z-axis direction, and the extension 222b has a limiting surface 222c and a transition surface 222d. The limiting surface 222c is the surface of the extension 222b in the -X-axis direction. The limiting portion 122 includes a mating surface 122a located on the +X-axis side, and the mating surface 122a is the surface of the limiting portion 122 in the +X-axis direction. The limiting surface 222c cooperates with the matching surface 122a to limit the positional relationship between the locking mechanism 22 and the movable part 12 in the X-axis direction, and prevents the movable part 121 from moving in the +X-axis direction. The limiting surface 222c can be a surface parallel to the Z-axis, or a surface intersecting the Z-axis, as long as it can achieve the effect of limiting the positional relationship between the positioning member 223a and the limiting groove 121a in the X-axis direction. The transition surface 222d is a surface connecting the limiting surface 222c and the bottom surface of the extension part 222b. The function of the transition surface 222d can guide the limiting surface 222c to match the matching surface 122a along the Z-axis direction. Furthermore, the stopper 222 is arranged above the positioning member 223a, that is, the stopper 222 is arranged in the +Z axis direction of the engaging portion 223, and the stopper surface 222c is arranged in the +Z axis and +X axis directions of the engaging surface 223b. This structure is conducive to the engaging surface 223b being closer to the inside of the ink cartridge than the stopper surface 222c, so that the positioning member 223a is closer to the stopper 222 than the main body 221. The manufacturing error of the positioning member 223a is smaller and it is less likely to deform, so that the engagement between the positioning member 223a and the stopper groove 121a is more firm and stable.

[0053] In the above embodiment, the positioning member 223a is a protrusion provided on the main body 221, two or more positioning members 223a are provided, and in the Y-axis direction, the positioning members 223a are respectively provided on both sides of the limiting member 222. The limiting member 222 can be slightly rotated in the second direction, or the limiting member 222 has a certain elasticity relative to the main body 221, and the two can deflect at a certain angle.

[0054] Please continue to refer to Figure 2 and Figure 6As shown, the mounting seat body 11 is roughly in the shape of a rectangular parallelepiped, and the mounting seat body 11 is provided with a mounting cavity 110, and the mounting cavity 110 can be installed with multiple ink cartridges 2. And the mounting cavity 110 includes a bottom wall 110a, a first side wall 110b, a second side wall 110c, a third side wall 110d and a fourth side wall 110e, the first side wall 110b and the second side wall 110c are arranged oppositely, and the third side wall 110d and the fourth side wall 110e are arranged oppositely. The second side wall 110c is provided with a positioning groove 111, and the positioning groove 111 is arranged correspondingly to the positioning column 23. The ink cartridge mounting seat 1 also includes a bracket 13, an ink tube 14 and a contact needle part 15, the ink tube 14 and the contact needle part 15 are respectively arranged on the bottom wall 110a of the mounting cavity 110, the ink tube 14 is arranged correspondingly to the position of the ink outlet 25, and the contact needle part 15 is arranged correspondingly to the position of the chip 24. The bracket 13 is installed on the first side wall 110b.

[0055] Please continue to refer to Figure 7 As shown, the movable member 12 further includes a push portion 123 and a rotating shaft 124. The engaging portion 121, the limiting portion 122, the rotating shaft 124 and the push portion 123 are arranged on the movable member 12, and the limiting groove 121a is arranged opposite to the limiting portion 122. The movable member 12 is rotatably connected to the bracket 13 through the rotating shaft 124, and the combination of the movable member 12 and the bracket 13 is installed on the ink cartridge mounting seat 1 through the bracket 13. The limiting portion 122 and the push portion 123 are both arranged on the +X axis side of the movable member 12.

[0056] In the present embodiment, three limiting grooves 121a are provided, and the three limiting grooves 121a are distributed along the Y-axis direction. However, in the present embodiment, the number of positioning members 223a is two, which are engaged with two of the three limiting grooves 121a. It can be understood that in other embodiments, one limiting groove 121a can also be provided, or two or more than two, as long as the number of limiting grooves 121a is equal to or greater than the number of positioning members 223a. A plurality of positioning members 223a are provided in the Y-axis direction, which is conducive to maintaining the stability of the ink cartridge 2 and preventing the ink cartridge 2 from shaking or deflecting in the YZ plane.

[0057] Please refer to Figure 2 , Figure 8 , Fig. 9As shown, when the ink cartridge 2 is installed in the installation cavity 110 of the ink cartridge installation seat 1, the engaging mechanism 22 moves in the -X axis direction, and the positioning column 23 extends into the positioning groove 111 and engages with the positioning groove 111. The abutting portion 225 abuts against the bracket 13, the positioning member 223a extends into the limiting groove 121a, engages with the limiting groove 121a, and the joint surface 223b abuts against the inner wall of the limiting groove 121a. The limiting member 222 cooperates with the limiting portion 122, and the limiting surface 222c abuts with the matching surface 122a, limiting the positional relationship between the positioning member 223a and the limiting groove 121a in the X-axis direction. The ink outlet 25 cooperates with the ink tube 14 to provide ink for the printing task of the printing device, and can supply the ink in the ink cartridge 2 to the print head. The chip 24 abuts against the stylus portion 15 to transmit data between the ink cartridge 2 and the printing device.

[0058] When the ink cartridge 2 is installed on the ink cartridge mount 1, the abutment portion 225 abuts against the bracket 13, so that the locking mechanism 22 moves in the -X axis direction, so as to move the locking mechanism 22 in advance and reduce the installation force of the user when installing the ink cartridge 2 on the ink cartridge mount 1.

[0059] In other embodiments, when the ink cartridge 2 is installed on the ink cartridge mounting seat 1 , the abutting portion 225 abuts against the bracket 13 to determine the positional relationship between the engaging mechanism 22 and the ink cartridge mounting seat 1 .

[0060] In the above embodiment, the positioning column 23 is prevented from moving in the +Z axis direction by the positioning groove 111 limiting the positioning column 23, and the positioning member 223a is prevented from moving in the +Z axis direction by the limiting groove 121a limiting the positioning member 223a, thereby preventing the ink cartridge 2 from being separated from the ink cartridge mounting seat 1 in the opposite direction (+Z direction) of the installation direction. The limiting action of the limiting member 222 and the limiting portion 122 further limits the positional relationship between the movable engaging mechanism 22 and the movable movable member 12 in the X axis direction, thereby preventing the positioning member 223a from being separated from the limiting groove 121a, thereby preventing the ink cartridge 2 from being separated from the ink cartridge mounting seat 1.

[0061] For further information, please refer to Figure 2 As shown, when the ink cartridge 2 is installed in the ink cartridge mounting seat 1, the ink cartridge 2 is subjected to a force F1 given by the ink tube 14, the ink cartridge 2 is subjected to a force F2 given by the stylus portion 15, the ink cartridge 2 is subjected to a force F3 by the limiting groove 121a and the positioning groove 111, and the positioning member 223a of the ink cartridge 2 gives the movable member 12 a reaction force F3' opposite to the force F3. When the forces F1 and F2 are large, although the reaction force F3' will also increase, the movable member 12 can be prevented from rotating due to the action of the limiting member 222, thereby preventing the ink cartridge 2 from detaching from the ink cartridge mounting seat 1.

[0062] Please continue to refer to Figure 2As shown, when removing the ink cartridge 2, the user pushes the push portion 123 by hand to rotate the movable member 12 counterclockwise, and the engaging mechanism 22 also moves in the +Z direction. The engaging mechanism 22 is offset at a certain angle relative to the mounting hole 211, that is, the engaging mechanism 22 is slightly tilted in the +Z axis direction relative to the ink cartridge 2, and the limiting member 222 is separated from the limiting portion 122. At this time, the user continues to push the push portion 123 for a certain distance, then stops pushing the push portion 123, and lets go, and the movable member 12 is quickly reset under the action of its restoring force (a restoring spring is provided on the ink cartridge mounting seat 1 to return the movable member 12 to the initial position). However, the recovery speed of the locking mechanism 22 is slow, so the joint surface 223b is separated from the inner wall of the limiting groove 121a, and the positioning member 223a is separated from the limiting groove 121a. Under the action of the ink tube 14 and the stylus portion 15, the ink cartridge 2 pops up, and the positioning member 223a is separated from the limiting groove 121a, thereby separating the ink cartridge 2 from the ink cartridge mounting seat 1, and the ink cartridge 2 can be removed.

[0063] Based on the above embodiments, this application also discloses a specific implementation method, please refer to Fig.10 As shown, the difference between this embodiment and the above embodiments is that, in this embodiment, the limiting member 222 and the engaging portion 223 are split structures, that is, the limiting member 222 and the engaging portion 223 are two separate components that are independently provided.

[0064] The limiting member 222 also includes an operating portion 222e, which is arranged in the +Z axis direction of the extending portion 222b, that is, the operating portion 222e is arranged in the +X axis direction of the first side surface 202. When removing the ink cartridge 2 from the ink cartridge mounting seat 1, the user pushes the operating portion 222e, the limiting member 222 is disengaged from the limiting portion 122, and then pushes the pushing portion 123, the positioning member 223a is disengaged from the limiting groove 121a, and then the ink cartridge 2 is disengaged from the ink cartridge mounting seat 1, and the ink cartridge 2 can be removed. The limiting member 222 and the engaging portion 223 are separately arranged, which is more conducive to the separation of the limiting member 222 from the limiting portion 122 and the separation of the positioning member 223a from the limiting groove 121a when the ink cartridge 2 is removed from the ink cartridge mounting seat 1.

[0065] The present application also discloses a specific implementation manner, in which the operating portion 222e of the limiting member 222 can be arranged on the top surface 206 (i.e., an opening is provided on the top surface 206, and the operating portion 222e is exposed on the top surface 206), so that when the ink cartridge 2 is removed from the ink cartridge mounting seat 1, the user can operate the operating portion 222e on the top surface 206, which is more convenient.

[0066] Furthermore, the operating portion 222e of the limiting member 222 may also be disposed on the third side surface 203 or the fourth side surface 204. As long as it is convenient for the user to operate, the beneficial effects of this embodiment can be achieved.

[0067] Based on the above embodiments, this application also discloses a specific implementation method, please refer to Fig.11 The difference between this embodiment and the above embodiment is that, in this embodiment, the engaging mechanism 22 includes a handle 227, a stopper 222, an engaging portion 223 and a pushing portion 222f. The handle 227 is connected to the ink cartridge body 21, and the handle 227 can rotate around the connection between the handle 227 and the ink cartridge body 21. The stopper 222, the engaging portion 223 and the pushing portion 222f are respectively arranged on the handle 227.

[0068] When the ink cartridge 2 is installed in the ink cartridge mounting seat 1, the positioning member 223a is engaged with the limiting groove 121a, and the limiting member 222 is in contact with the limiting portion 122. When the user removes the ink cartridge 2 from the ink cartridge mounting seat 1, the user pushes the pushing portion 222f to separate the limiting member 222 from the limiting portion 122, and then the positioning member 223a is separated from the limiting groove 121a, and then the ink cartridge 2 is separated from the ink cartridge mounting seat 1, and the ink cartridge 2 can be removed.

[0069] In order to protect the ink cartridge when not in use, the ink cartridge device further comprises a protective cover 3 . When the ink cartridge 2 is removed, the ink outlet 25 of the ink cartridge can be placed in the protective cover 3 .

[0070] Based on the above embodiments, please refer to Fig.12 and Fig.13 As shown, the solid line represents the engaging mechanism 22, the dotted line represents the movable member 12, and the limiting surface 222c can be set in the +Z and +X axis directions of the joint surface 223b (as shown in FIG. Fig.12 ), or it can be set in the +Z, -X axis direction (as shown in Fig.13 ), or it can be set in the positive direction of the +Z axis.

[0071] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
