[0045] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0046] like Figures 1 to 5 As shown, an embodiment of the present utility model provides an ink cartridge 20 that can be inserted into a mounting portion 10 of a printing device, wherein the printing device can be an inkjet printer.

[0047] In order to better illustrate the various components of the mounting portion 10 and the ink cartridge 20, a three-dimensional rectangular coordinate system is established. Among the three spatial axes, namely the X-axis, Y-axis, and Z-axis, which are orthogonal to each other, the Z-axis represents the vertical direction, the X-axis and the Y-axis represent the directions along the horizontal plane, and the directions of the arrows along the X-axis, the Y-axis, and the Z-axis are set to the +X direction, the +Y direction, and the +Z direction, respectively, wherein the -Z-axis direction is the plumb bob direction (gravity direction).

[0048] The utility model also defines a first direction D1, a second direction D2 and a third direction D3, wherein the first direction D1 is the +Y axis direction, the second direction D2 is the +Z axis direction, and the third direction D3 is the X axis direction, and defines that the first direction end of each component of the mounting portion 10 and the ink cartridge 20 is one side of the +Y axis direction of each component, and the second direction end is one side of the +Z axis direction of each component.

[0049] [Structure of the mounting portion 10]

[0050] like Figures 1 to 3 As shown, the mounting portion 10 has a box-shaped frame 11, a rotating shaft 13, a supporting component 12 and a liquid inlet portion 14. The supporting component 12, the rotating shaft 13 and the liquid inlet portion 14 are arranged in the frame 11. The frame 11 is provided with an insertion port 111 at the -Y axis end. The ink cartridge 20 is inserted into the frame 11 through the insertion port 111. The installation process of the ink cartridge 20 includes a translation operation of horizontal movement along a first direction D1, that is, the ink cartridge 20 moves toward the inner side (+Y axis side) of the frame 11 after being inserted from the insertion port 111.

[0051] The support member 12 has a guide path 121 extending along the +Y axis direction, and the guide path 121 is used to guide the ink cartridge 20 to the first posture A1 ( Figure 1 The supporting member 12 (indicated by a single dotted line) moves along the +Y axis direction, and the supporting member 12 has a front end area (-Y axis end) where the starting end of the guide path 121 is located, and a base end area (+Y axis end) where the terminal end of the guide path 121 is located, and the base end area of ​​the supporting member 12 and the rotating shaft 13 are arranged on the inner side of the frame 11 (i.e., away from the insertion port 111).

[0052] In a feasible implementation mode, referring to Figure 2As shown, the supporting component 12 has a bottom plate 122 and two side ribs 123. The two side ribs 123 are respectively arranged at two ends of the bottom plate 122 in the width direction (X-axis direction). The bottom plate 122 and the two side ribs 123 surround a receiving groove 124. The receiving groove 124 extends along the Y-axis direction. A second electrical connection portion 125 is arranged in the base end area (+Y-axis end) of the receiving groove 124. The second electrical connection portion 125 is used to engage (electrically connect) with the first electrical connection portion 214 on the ink cartridge 20. The second electrical connection portion 125 has a certain activity space in the three directions of XYZ, so that when the external environment changes, it can still maintain a stable abutment with the first electrical connection portion 214.

[0053] like Figure 1 As shown, the rotation shaft 13 has an axis extending in the X-axis direction and is disposed at the base end region (+Y-axis end) of the support member 12. The support member 12 is rotatably supported in the frame 11 by the rotation shaft 13, and the support member 12 can guide the ink cartridge 20 to rotate synchronously. There are two positions on the rotation path of the support member 12, namely, the guiding position B1 and the connecting position B2 ( Figure 1 When the support member 12 is at the guide position B1, the ink cartridge 20 is in the first posture A1 ( Figure 1 When the support member 12 is at the connection position B2, the ink cartridge 20 is in the second posture A2 ( Figure 1 In this case, the ink cartridge 20 is connected to the liquid introduction portion 14. Fig. 9 as well as Fig.10 As shown, the mounting portion 10 is provided with a first restricting portion 16 for maintaining the ink cartridge 20 in the second posture A2 and maintaining the supporting member 12 in the connection position B2.

[0054] like Figure 1 As shown, the mounting portion 10 may also include a biasing member 15 for biasing the support member 12 from the connection position B2 toward the guide position B1. The biasing member 15 is, for example, a coil spring. In the initial state where the ink cartridge 20 is not in the mounting portion 10, the support member 12 is biased by the biasing member 15 and is arranged in the guide position B1.

[0055] like Figures 1 to 3As shown, the liquid introduction portion 14 is arranged below the support member 12 (-Z axis side). When the support member 12 is in the connection position B2, the liquid introduction portion 14 is connected to the ink cartridge 20. The liquid introduction portion 14 can also be arranged in a posture inclined relative to the guide path 121. In more detail, the liquid introduction portion 14 can also be inclined in a manner such that its front end (upper end) is arranged closer to the insertion port 111 in the Y axis direction than the base end (lower end). For example, the center line of the liquid introduction portion 14 can form an angle greater than 0° and less than 15° relative to the vertical direction (-Z axis direction).

[0056] [Structure of ink cartridge 20]

[0057] Reference Figures 4 to 8 As shown, the ink cartridge 20 includes an ink storage member 21 and a coupling member 22 detachably mounted on the bottom of the ink storage member 21. To better illustrate the structure of the ink cartridge 20, the surfaces of the various components in the ink cartridge 20 are now defined. The two relative surfaces in the first direction D1 are defined as the front side surface and the rear side surface, respectively, wherein the front side surface is located in the +Y axis direction of the rear side surface. The two relative surfaces in the second direction D2 are defined as the top surface and the bottom surface, respectively, wherein the top surface is located in the +Z axis direction of the bottom surface. The two relative surfaces in the third direction D3 are defined as the left side surface and the right side surface, respectively, wherein the right side surface is located in the +X axis direction of the left side surface.

[0058] Reference Figures 7 to 10 As shown, the coupling member 22 has a first restricted portion 223, and the first restricted portion 223 is used to form a limiting fit with the first limiting portion 16 in the mounting portion 10 to limit the movement of the ink cartridge 20 in the second direction D2. In a feasible implementation, the first restricted portion 223 is a groove recessed toward the first direction D1, and the first limiting portion 16 is a protrusion protruding toward the first direction D1. Preferably, guide sliding slopes are formed on opposite sides of the protrusion along the Z-axis direction. When the supporting component 12 rotates to the connection position B2, the protrusion extends into the groove, and at least one guide sliding slope of the protrusion abuts against the inner wall surface of the groove to limit the movement of the ink cartridge 20, so that the supporting component 12 is limited to the connection position B2, and the ink cartridge 20 remains in the second posture A2. Those skilled in the art will appreciate that the first restricted portion 223 may be a protrusion, and the first limiting portion 16 may be a groove, which may also achieve the technical effect of limiting the movement of the ink cartridge 20. The number and distribution of the first restricted portion 223 and the first limiting portion 16 are not limited herein.

[0059] In the embodiment provided by the utility model, the ink storage member 21 has a first electrical connection portion 214, and the first electrical connection portion 214 includes a chip. When the ink cartridge 20 is inserted into the installation cavity of the printing device along the first direction D1 and reaches the base end area, the chip abuts against the second electrical connection portion 125 to achieve electrical connection.

[0060] The ink storage member 21 is at least partially located at the second direction end of the joint member 22. Figure 4 as well as Figure 5 As shown, the coupling member 22 is located below the ink storage member 21, and the orthographic projection of the coupling member 22 in the second direction D2 is offset from the orthographic projection of the first electrical connection portion 214 in the second direction D2. In the +Y axis direction, the coupling member 22 and the first electrical connection portion 214 are arranged in sequence, and the first electrical connection portion 214 is located at the first direction end of the coupling member 22. There is a certain distance between the first electrical connection portion 214 and the coupling member 22, and this distance can be determined according to actual conditions and is not limited here. When the ink cartridge 20 is installed into the mounting portion 10, in the first direction D1, the first electrical connection portion 214 enters the mounting portion 10 earlier than the coupling member 22.

[0061] Compared with the conventional ink cartridge 20 structure, the utility model sets the first electrical connection part 214 (chip) on the ink storage part 21, instead of setting the first electrical connection part 214 on the coupling part 22. The coupling part 22 does not need to extend to the front end of the ink storage part 21, thereby reducing the size of the coupling part 22 as an adapter and reducing its structural complexity. It also helps to reduce the number of snap-fit ​​structures between the coupling part 22 and the ink storage part 21, reducing the difficulty of disassembly and assembly between the two.

[0062] Preferably, the ink storage member 21 and the connecting member 22 are detachably connected, and the ink storage member 21 and the connecting member 22 are independently molded, which can reduce the difficulty of molding the ink cartridge 20. At the same time, since the chip is arranged on the ink storage member 21, when the ink in the ink storage member 21 is used up, the chip displays that there is no ink, and only the ink storage member 21 can be replaced without replacing the connecting member 22, thereby saving replacement materials and reducing costs.

[0063] In a feasible implementation manner, the detachable connection method is specifically a snap-fit ​​connection, referring to Figure 4 as well as Figure 5 As shown, the ink storage member 21 is provided with a locking mechanism 215, which is located at the opposite end of the ink storage member 21 in the first direction D1. The coupling member 22 is provided with a locked mechanism 224, which is located at the first direction end of the coupling member 22.

[0064] The engaging mechanism 215 and the engaged mechanism 224 form an engaging connection, thereby connecting the ink storage component 21 and the coupling component 22 as a whole. Since the engaging mechanism 215 and the engaged mechanism 224 are both distributed in the first direction D1, the operator can smoothly apply force to the engaging connection and release the force from the engaging connection, thereby simplifying the structure of the ink cartridge 20 and reducing the difficulty of disassembly and assembly.

[0065] Initially, the ink storage component 21 and the connecting component 22 remain separated. When the ink storage component 21 and the connecting component 22 need to be assembled together, the engaging mechanism 215 and the engaged mechanism 224 are aligned in the first direction D1, and then the two are brought closer to each other until the engaged mechanism 224 and the engaging mechanism 215 are engaged and connected, thereby realizing that the ink storage component 21 and the connecting component 22 are assembled as a whole. When the ink storage component 21 and the connecting component 22 need to be separated, the operator applies force to disengage the engaging mechanism 215 from the engaged mechanism 224, thereby separating the ink storage component 21 and the connecting component 22.

[0066] In the embodiment provided by the utility model, the engaging mechanism 215 is a groove formed by being recessed in the first direction D1 on the side wall of the ink storage member 21, and the engaged mechanism 224 is a claw protruding in the first direction D1 on the side wall of the coupling member 22. In the cross section along the plane where the YZ axis is located, the claw is hook-shaped, and the outer contour surface of the claw is matched with the inner contour surface of the groove. It can be known by those skilled in the art that the engaging mechanism 215 can also be set as a claw, and the engaged mechanism 224 can be set as a groove, and no limitation is made here.

[0067] Preferably, reference Figure 5 As shown, the locking mechanism 215 includes a first locking portion 2151 and a second locking portion 2152, and the first locking portion 2151 and the second locking portion 2152 are both locking grooves. The inner contour surfaces of the first locking portion 2151 and the second locking portion 2152 may be the same or different, and are not limited here. In the first direction D1, the second locking portion 2152, the first locking portion 2151, and the first electrical connection portion 214 are arranged in sequence at intervals, and the second locking portion 2152 is located at the second direction end of the first locking portion 2151. The first locking portion 2151 and the second locking portion 2152 are both at a certain distance from the first electrical connection portion 214, so as to minimize the chip in the first electrical connection portion 214 from being squeezed and collided during the movement of the connecting member 22 or the operation of the operator when the connecting member 22 is installed or disassembled with the ink storage member 21, thereby reducing the chip damage caused by the squeezing and collision.

[0068] In a feasible implementation mode, referring to Figure 4 as well as Figure 5As shown, the ink storage member 21 includes a first ink storage body 211, a second ink storage body 212 and a third ink storage body 213. Preferably, the first ink storage body 211, the second ink storage body 212 and the third ink storage body 213 are all integrally formed. In the second direction D2, the third ink storage body 213, the second ink storage body 212 and the first ink storage body 211 are sequentially distributed. In the first direction D1, the length of the second ink storage body 212 is less than the length of the first ink storage body 211. The chip is arranged in the second ink storage body. On the front side surface of the main body 212, the second locking portion 2152 is recessed toward the first direction D1 on the rear side surface of the second ink storage body 212, and the portion of the first ink storage body 211 that exceeds the second ink storage body 212 can protect the chip from impact from the side or top, reducing the possibility of chip damage by bumps. The third ink storage body 213 is protruding from the bottom surface of the second ink storage body 212, and the first locking portion 2151 is recessed toward the first direction D1 on the side surface of the third ink storage body 213.

[0069] The engaged mechanism 224 includes a first engaged portion 2241 cooperating with the first engaged portion 2151 and a second engaged portion 2242 cooperating with the second engaged portion 2152. The first engaged portion 2241 is located at a first direction end of the second engaged portion 2242, and the second engaged portion 2242 is located at a second direction end of the first engaged portion 2241.

[0070] In a feasible implementation mode, referring to Figures 5 to 8 As shown, the coupling member 22 includes a first coupling body 221 and a second coupling body 222. The first coupling body 221 is a block extending along the first direction D1, and the first clamped portion 2241 is integrally formed at the first direction end of the first coupling body 221. The second coupling body 222 is a block extending along the second direction D2, and the second clamped portion 2242 is integrally formed at the first direction end of the second coupling body 222.

[0071] When the ink storage component 21 and the coupling component 22 are connected as one, the top surface of the first coupling body 221 is attached to the bottom surface of the second ink storage body 212, the first clamped portion 2241 extends into the first clamping portion 2151, the front side surface of the second coupling body 222 is attached to the rear side surface of the second ink storage body 212, and the second clamped portion 2242 extends into the second clamping portion 2152, thereby combining the ink storage component 21 and the coupling component 22 into a stable and reliable whole.

[0072] Further, refer to Figures 5 to 8As shown, in the third direction D3, the first clamped portion 2241 is offset from the second clamped portion 2242, and the orthographic projection of the opposite end of the second clamped portion 2242 in the first direction D1 is offset from the orthographic projection of the opposite end of the first clamped portion 2241 in the second direction D2. In a feasible implementation, at least two second clamped portions 2242 are provided, and in the third direction D3, the first clamped portion 2241 is located between the two second clamped portions 2242, so that in the third direction D3, there are more connection points between the ink storage member 21 and the coupling member 22, and the covered area is uniform, thereby improving the connection stability between the ink storage member 21 and the coupling member 22, avoiding the occurrence of warping, resulting in a gap between the surface of the coupling member 22 and the liquid inlet portion 14 when the outlet portion 217 and the liquid inlet portion 14 are docked, which may cause ink leakage.

[0073] In the embodiment provided by the utility model, the ink storage member 21 is provided with a second restricted portion 216, and the second restricted portion 216 is located at the third directional end of the chip. Figure 4 as well as Figure 5 As shown, the second restricted portion 216 is a groove recessed on the second ink storage body 212. The groove is arranged on opposite sides of the second ink storage body 212 in the third direction D3, and is arranged close to the front side of the second ink storage body 212. The groove forms an opening on the front side of the second ink storage body 212.

[0074] To form a limiting fit with the second restricted portion 216, refer to Figure 2 as well as Figure 3 As shown, a second limiting portion 17 is also provided in the mounting portion 10. The second limiting portion 17 is a protrusion protruding from the two ribs of the supporting component 12. The protrusion is arranged close to the second electrical connection portion 125. The protrusion extends along the first direction D1. The outer contour surface of the second limiting portion 17 is adapted to the inner contour surface of the second restricted portion 216.

[0075] When the ink cartridge 20 is inserted into the frame 11 through the insertion port 111 in the first posture A1, it moves along the guide path 121 until the first electrical connection portion 214 abuts against the second electrical connection portion 125. At this time, the second limiting portion 17 extends into the second restricted portion 216 to form a limit fit, thereby limiting the shaking of the first electrical connection portion 214, so that the first electrical connection portion 214 and the second electrical connection portion 125 maintain stable abutment when the external environment changes.

[0076] Those skilled in the art will appreciate that the second limiting portion 17 may be a bump, and the second restricted portion 216 may be a groove. The second limiting portion 17 and the second restricted portion 216 may also be disposed on only one side of the chip, which is not limited here.

[0077] Reference Fig. 9as well as Fig.10 As shown, in the embodiment provided by the utility model, the joint member 22 is provided with an unlocking portion 225, which is a convex block convexly provided on the bottom surface of the joint member 22, and the convex block is provided close to the rear side surface of the joint member 22, and a first direction end of the unlocking portion 225 is formed with a contact surface 2251. The frame 11 is provided with a blocking portion 112, and the blocking portion 112 is preferably a plate extending along the first direction D1 and the third direction D3. The support component 12 is provided with a locking member 18, and the first end of the locking member 18 is pivotally connected to the support component 12, and the second end of the locking member 18 is formed with a contact surface 181.

[0078] In the initial state, when viewed along the -D2 direction, the portion of the locking member 18 located at the ends of the D1 and -D2 directions overlaps with the blocking portion 112, so that the rotation of the supporting component 12 is restricted by the blocking portion 112. When the ink cartridge 20 is inserted into the receiving groove 124 of the supporting component 12 in the first posture A1, the supporting component 12 is in the guiding position B1. During the movement of the ink cartridge 20 along the first direction D1, the abutting surface 2251 of the unlocking portion 225 abuts against the abutted surface 181 of the locking member 18, applying a horizontal force to the locking member 18, driving the locking member 18 to rotate until when viewed along the -D2 direction, the portion of the locking member 18 located at the ends of the D1 and -D2 directions no longer overlaps with the blocking portion 112, and the blocking portion 112 no longer restricts the rotation of the supporting component 12. The supporting component 12 rotates from the guiding position B1 to the connecting position B2, and the ink cartridge 20 rotates synchronously with the supporting component 12.

[0079] Preferably, reference Fig. 9 as well as Fig.10 As shown, a rebound member 126 is also provided in the supporting component 12. The rebound member 126 is preferably a leaf spring or a spring, etc. The rebound member 126 is connected to the locking member 18. When the unlocking portion 225 pushes the locking member 18 to move, the rebound member accumulates elastic restoring force. When the resisted surface 181 of the locking member 18 is out of contact with the resisting surface 2251 of the unlocking portion 225, the elastic restoring force applied by the rebound member 126 drives the locking member 18 back to its original position.

[0080] To locate the ink cartridge 20 in the mounting portion 10, refer to Figure 6 , Fig. 9 as well as Fig.10 As shown, a positioning portion 226 is provided on the joint member 22, and a positioning matching portion 19 is provided in the mounting portion 10. The positioning matching portion 19 is used to match with the positioning portion 226. One of the positioning portion 226 and the positioning matching portion 19 is a protrusion, and the other is a groove.

[0081] In the embodiment provided by the utility model, the positioning portion 226 is a groove recessed along the second direction D2 on the bottom surface of the coupling member 22, the positioning matching portion 19 is a protrusion arranged in the mounting portion 10, and the outer contour surface of the positioning matching portion 19 matches the inner contour surface of the positioning portion 226. During the process of the supporting component 12 rotating from the guide position B1 to the connection position B2, the positioning matching portion 19 extends into the positioning portion 226. If the ink cartridge 20 does not move to the preset position in the receiving groove 124 of the supporting component 12, the positioning matching portion 19 will abut against the bottom surface of the coupling member 22, causing interference, and the supporting component 12 cannot rotate, thereby ensuring that the ink cartridge 20 reaches the preset position in the receiving groove 124, and the first electrical connection portion 214 remains abutted against the second electrical connection portion 125.

[0082] In the embodiments provided by the present utility model, refer to Figure 4 as well as Figure 5 As shown, the ink storage member 21 is provided with an ink storage cavity for accommodating ink, and the ink storage member 21 is provided with a lead-out portion 217 connected to the ink storage cavity. The lead-out portion 217 protrudes from the bottom surface of the second ink storage body 212, and the lead-out portion 217 forms an opening at the opposite end of the second direction D2, and the opening is connected to the ink storage cavity. The joint member 22 is provided with an opening 227, and the opening 227 penetrates the joint member 22 in the second direction D2. The projections of the opening 227 and the lead-out portion 217 in the second direction D2 are at least The outlet portion 217 is partially overlapped, and is exposed through the opening portion 227. The outlet portion 217 includes a cylindrical structure extending in a direction away from the ink storage cavity, and the cylindrical structure has a central axis. A valve structure for opening and closing a flow path for the circulation of a liquid medium is arranged in the outlet portion 217. The valve structure includes a valve seat and a valve core. The valve seat and the valve core are coaxially arranged with the central axis of the cylindrical structure. When the ink cartridge 20 is installed in place in the mounting portion 10, the outlet portion 217 docks with the liquid inlet portion 14 and outputs ink to the printer.

[0083] Further, refer to Figure 5As shown, the ink cartridge 20 further includes an absorbing component 23 disposed between the ink storage member 21 and the coupling member 22. The inner diameter of the opening 227 is slightly larger than the outer diameter of the outlet portion 217. The opening 227 and the outlet portion 217 are coaxially arranged to form an annular gap therebetween. The positive projection of the absorbing component 23 in the first direction D1 overlaps with the outlet portion 217. At least a portion of the absorbing component 23 is located in the annular gap to absorb the leaked ink. The absorbing component 23 is preferably an adsorbent such as a sponge. The absorbing component 23 is attached to the top surface of the coupling member 22. A through hole is provided through the absorbing component 23. The position of the through hole is opposite to the position of the opening 227. The inner diameter of the through hole matches the outer diameter of the outlet portion 217. When the ink storage member 21 and the coupling member 22 are connected as one, the side of the absorbing component 23 facing away from the coupling member 22 is attached to the bottom surface of the second ink storage body 212. After the ink is sent out from the outlet portion 217, the absorbing component 23 can absorb the leaked ink to prevent the ink from flowing to the outside of the ink cartridge 20 to cause pollution or affect the appearance.
