[0048] In the field of inkjet printing, currently, a tray-type housing paired with an ink bag-type liquid containing device is a relatively common type of large-capacity split ink cartridge solution. During installation, the ink bag needs to be vertically inserted into the housing from top to bottom. There is a protruding portion extending along the installation direction inside the housing to guide the installation of the liquid containing device. The liquid containing device includes a connecting component. The existing connecting component needs to cooperate and be fixed with both the installation part of the printer and the tray-type housing. The tray-type housing itself already has a connecting structure for cooperating with the installation part of the printer. However, the ink bag is a consumable, and setting the above two types of connecting structures on the ink bag will significantly increase the structural complexity, thereby increasing the production and manufacturing cost of the ink bag and the R & D difficulty.

[0049] The following uses specific embodiments to elaborate in detail on the technical solution of the present invention and how the technical solution of the present invention solves the above technical problems. It should be noted that the following several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0050] It should be noted that the content of the following Embodiment 2 is the main protection solution of this application, and other embodiments are other deformation solutions related to this application in the priority document to help understand the technical content of Embodiment 2 by reference.

[0051] As Figure 1As shown in the figure, the specific structure of the installation part 50 of the inkjet printer includes a fixing frame, on which an ink injection tube 51, a printer electrical connection part 52, columnar positioning parts 53f and 53s, and a locking part 54 are provided. The locking part 54 is a rod-shaped component that can be reset and swing. The rod-shaped component is provided with a protrusion extending in the -Z direction at the movable end, and the protrusion is used to cooperate with the groove at the bottom of the housing 20 to fix the assembly composed of the housing 20 and the liquid storage device 10. The printer electrical connection part 52 can be electrically connected to the chip on it in the state where the assembly is installed on the installation part 50. The printer electrical connection part 52 includes multiple contact pins (not marked in the figure) made of elastic conductive steel sheets. Specifically, the above-mentioned assembly is installed or removed along the +Y and -Y directions in the figure. This assembly is physically engaged with the installation part through the housing and is electrically connected to the electrical connection part 52 through the chip located on the liquid storage device.

[0052] Embodiment 1

[0053] As Figure 2 shown, the liquid storage device 10 includes a connection component 11 and a liquid storage body 12 for storing liquid. The connection component 11 is recessed at the end along the +Y direction to provide an electrical connection part 13, and a chip 14 is inclinedly installed on the electrical connection part 13.

[0054] As Figure 3 and Figure 4 shown, the housing 20 includes a bottom plate 21 and an outer frame 22 provided at the edge of the bottom plate 21. The bottom plate 21 is a rectangular plate, and the length of the bottom plate 21 in the Y-axis direction is greater than the length of the bottom plate 21 in the X-axis direction. The outer frame 22 includes a front baffle 221, a rear baffle 222, two side baffles 223, and two side edges 224. The front baffle 221 is provided at the edge of the +Y direction end of the bottom plate 21, the rear baffle 222 is provided at the edge of the -Y direction end of the bottom plate 21, the two side baffles 223 are oppositely arranged at the edges of the bottom plate 21 in the +X and -X directions, the side edges 224 protrude at the junction of the side baffle 223 and the bottom plate 21, and the side edges 224 extend along the Y-axis direction. Each end of the side baffle 223 is integrally connected to the front baffle 221 and the rear baffle 222. Two protruding parts 23 are vertically provided at the first end of the bottom plate 21. In this embodiment, the protruding parts 23 are columnar parts. A first notch 211 is provided at the edge of the +Y direction end of the bottom plate 21. The length of the side edge 224 is less than the length of the bottom plate 21 in the Y-axis direction, and the end face of the side edge 224 close to the front baffle 221 is a cut-off surface 227. A wedge-shaped convex part 213 is provided at the edge of the +Y direction end of the bottom plate 21 corresponding to the chip 14, and the included angle between the upper surface of the wedge-shaped convex part 213 and the inner wall surface of the front baffle 221 is an obtuse angle. A guiding groove 214 (not marked in the figure, for reference, see Figures 1 to 3 is not marked in the figure and can be referred to Figure 11 and Figure 19Understand this structure). The liquid containing device 10 is installed in the installation part 50 by means of the housing 20. The housing 20 includes positioning holes 24 that cooperate with the positioning parts 53f and 53s. The guiding groove 214 and the wedge-shaped convex part 213 at least partially coincide in the X direction.

[0055] The connecting component 11 is located above the +Y direction end of the bottom plate 21. In the X-axis direction, the connecting component 11 is at least partially between the two convex parts 23. The bottom of the connecting component 11 is at least partially attached to the bottom plate 21. The front baffle 221 is provided with a second notch 225 along the +Z direction at the upper edge. The connecting component 11 is provided with a liquid outlet part 111 that cooperates with the second notch 225 on the +Y direction side. The outer end of the liquid outlet part 111 protrudes from the outer wall of the front baffle 221.

[0056] The liquid containing device 10 further includes a limiting part 151 connected to the bottom plate 21. The front baffle 221 is further provided with a third notch 226 communicating with the second notch 225 at the upper edge. In the X-axis direction, the two ends of the third notch 226 are respectively on both sides of the second notch 225. In the Z-axis direction, the length of the third notch 226 is less than the length of the second notch 225. The limiting part 151 includes a first limiting plate 151a provided at the outer end of the liquid outlet part 111 and abutted against the outer side of the front baffle 221 and two second limiting plates 151b provided on the side of the connecting component 11 facing the front baffle 221 and abutted against the side edge of the third notch 226.

[0057] The liquid outlet part 111 includes two fitting sides 112 that abut against both sides of the second notch 225. The number of the first limiting plates 151a is two, and the two first limiting plates 151a are respectively arranged on the two fitting sides 112. The outer ends of the second limiting plates 151b are located outside the front baffle 221. The lower edges of the second limiting plates 151b abut against the lower edge of the third notch 226. The upper edge of the side baffle 223 is flush with the upper edge of the front baffle 221. The outer ends of the second limiting plates 151b are provided with a third limiting plate 151c that abuts against the front baffle 221 on the side facing away from the liquid outlet part 111. In the X-axis direction, the chip 14 is located between the liquid outlet part 111 and one of the third limiting plates 151c. The two ends of the side of the connecting component 11 away from the front baffle 221 in the X-axis direction are provided with avoiding notches 16 that cooperate with the convex parts 23.

[0058] The connecting component 11 is clamped with the front baffle 221 through the liquid outlet part 111 and the first limiting plate 151a at the second notch 225, and is clamped with the front baffle 221 through the second limiting plate 151b and the third limiting plate 151c at the third notch 226, which can ensure the limiting of the liquid containing device 10 in the length and width directions of the housing 20, and the connection point between the liquid containing device 10 and the housing 20 is closer to the chip 14, which can improve the contact stability between the chip 14 and the printer electrical connection part 52.

[0059] Example Two

[0060] This application provides a liquid containing device. The housing 20 in this embodiment is the same as that in Example One, and the specific structure can be referred to Figure 4 . The main difference between the liquid container 12 involved in this embodiment and that in Example One lies in the restricting member 152. As Figures 5 - 9 shown, the liquid containing device provided in this embodiment is detachably installed in the housing 20; the housing 20 includes a bottom plate 21, the liquid containing device is located on the bottom plate 21, and the first end edge of the bottom plate 21 has a first notch 211.

[0061] The liquid containing device includes a liquid container 12 and a connecting member 11. The connecting member 11 is fixed to one end of the liquid container 12 close to the first notch 211, and a chip 14 is provided at the connecting member 11 close to the first end edge of the bottom plate 21; the connecting member 11 includes a body and a restricting member 152, and the restricting member 152 is located on the side of the body close to the bottom plate 21; the restricting member 152 in this embodiment includes a passing-out portion 152a and a engaging portion 152b. The top end of the passing-out portion 152a is fixedly connected to the body, the bottom end of the passing-out portion 152a extends out from the first notch 211 to the lower side of the bottom plate 21, and the engaging portion 152b is provided at the bottom end of the passing-out portion 152a, and at least part of the projection of the engaging portion 152b on the bottom plate 21 falls outside the first notch 211.

[0062] It should be noted that in this embodiment, the restricting member 152 is provided in the area corresponding to the first notch 211 at the bottom of the connecting member 11, and the restricting member 152 is hooked to the bottom plate 21 at the first notch 211. Specifically, the restricting member 152 includes a passing-out portion 152a and a engaging portion 152b. The lower end of the passing-out portion 152a is located below the bottom plate 21, the engaging portion 152b protrudes from the -Y direction side of the lower end of the passing-out portion 152a, and the engaging portion 152b abuts against the side of the bottom plate 21 facing away from the liquid container 12. That is, the liquid container 12 in this embodiment can realize the limit in the X and Z directions with the housing 20 through the restricting member 152 hooked to the bottom of the bottom plate 21. Since the engaging portion 152b abuts against the lower side of the bottom plate 21, the moving space in the Y direction is extremely small, which can ensure the stable assembly of the liquid container 12. There is no need to provide other connection structures on the liquid container 12 that cooperate with the housing 20, nor is it necessary to provide connection structures that cooperate with the printer installation part, which helps to reduce the manufacturing cost of related consumables. And because the restricting member 152 is relatively close to the chip 14, the contact stability between the chip 14 and the printer electrical connection part can be improved.

[0063] In an alternative embodiment, as Figure 4As shown, the first notch 211 extends along the length direction of the bottom plate 21 , and the extension length of the limiting member 152 along the width direction of the bottom plate 21 matches the opening width of the first notch 211 .

[0064] The extension length of the limiting member 152 along the width direction of the housing 20 matches the opening width of the first notch 211 along the width direction of the housing 20. This arrangement allows both ends of the limiting member 152 to abut against the two side end surfaces of the first notch 211, thereby achieving a more stable limiting effect along the X direction.

[0065] Possible, combined Figure 4 and Figure 7 The first notch 211 has a U-shaped profile and has an arc-shaped end wall 212 . The side of the protruding portion 152 a facing the end wall 212 is an arc-shaped surface, and the curvature of the arc-shaped surface matches the curvature of the end wall 212 .

[0066] It should be noted that the protrusion portion 152a matches the end wall surface 212 of the first notch 211, so that the arc surface of the protrusion portion 152a can better abut against the end wall surface 212 of the first notch 211, thereby achieving a more stable limiting effect along the Y direction.

[0067] For example, Figure 8 As shown, the protrusion 152a is configured as an arc-shaped rib plate, the top end of the arc-shaped rib plate is fixedly connected to the main body, and the bottom end of the arc-shaped rib plate extends out of the bottom plate 21 along the first notch 211; the clamping portion is configured as an arc-shaped protrusion, and the arc-shaped protrusion is arranged on the side of the bottom end of the arc-shaped rib plate, and the arc-shaped protrusion abuts against the bottom surface of the bottom plate 21 opposite to the liquid container.

[0068] It can be understood that, specifically, the protrusion 152a is an arc-shaped rib plate whose side surface is in contact with the end wall surface 212, and the engaging portion 152b is an arc-shaped protrusion on the side surface of the arc-shaped rib plate of the protrusion 152a, and the upper surface of the arc-shaped protrusion of the engaging portion 152b abuts against the lower surface of the bottom plate 21 at the edge of the end wall surface 212. The use of the rib plate as the protrusion 152a can ensure the strength of the limiting member 152 and reduce the risk of damage caused by the limiting member 152 in the process of abutting against the bottom plate 21.

[0069] In one embodiment, Figure 4 As shown, the shell 20 includes a plurality of baffles arranged around the edges of the bottom plate 21 , and the shell 20 also includes a second notch 225 arranged on the baffle. The plurality of baffles include a front baffle 221 and side baffles 223 located at both ends of the front baffle 221 , and the second notch 225 is arranged on the front baffle 221 .

[0070] like Figure 6 and Figure 9As shown, the connecting component 11 includes a liquid outlet portion 111. The liquid outlet portion 111 is disposed at a position on the side of the main body corresponding to the second notch 225, and one end of the liquid outlet portion 111 facing away from the main body passes through the second notch 225 and protrudes outside the front baffle 221.

[0071] In this embodiment, when viewed from the outside of the front baffle 221, the liquid outlet portion 111 is a protrusion surrounding the edge of the second notch 225. The ink from the protruding liquid outlet portion 111 can play a guiding role during the installation of the liquid container 12.

[0072] It should be noted that the second notch 225 and the first notch 211 may be connected or not connected, and can be set according to the specific structure of the connecting component.

[0073] Regarding the specific connection method between the liquid container 12 and the connecting component 11, as Figure 6 shown, optionally, the main body of the connecting component 11 has a receiving cavity (not shown in the figure). One end of the liquid container 12 close to the main body is provided with a fixed joint 15, and the fixed joint 15 is snap-fitted into the receiving cavity. That is, the liquid container 12 is connected to the main body of the connecting component 11 by a snap-fitting method, and then indirectly connected to the housing 20 through the main body of the connecting component 11, thereby realizing the connection and fixation with the printer.

[0074] In order to facilitate the taking and placing of the liquid containing device, a gap can be provided between the main body of the connecting component 11 and the front baffle 221.

[0075] In addition, as Figure 4 shown, the first end of the bottom plate 21 has two protruding portions 23, and at least part of the connecting component 11 is located between the two protruding portions 23.

[0076] It should be noted that these two protruding portions 23 are structures existing on the bottom plate 21 itself, and the two protruding portions 23 are provided at both ends of the bottom plate 21 in the X direction. In this application, the liquid container 12 is directly fixed to the bottom plate 21 of the housing 20 through a simple hook connection structure, which simplifies the connection structure. Therefore, when setting the connecting component 11 of this application, the connecting component 11 does not need to be connected to the housing 20 by means of the two protruding portions 23, and the local structure can make an avoidance for the two protruding portions 23.

[0077] Possibly, the distance between the end wall surface 212 of the first notch 211 and the front baffle 221 is less than the distance from the protruding portion 23 to the front baffle 221, that is, the end wall surface 212 of the first notch 211 is closer to the front baffle 221 than the protruding portion 23. With such a setting, the restricting member 152 is closer to the chip 14 than the protruding portion 23, which can improve the contact stability between the chip 14 and the printer electrical connection portion 52.

[0078] In a specific embodiment, as Figure 4 shown, the first notch 211 can be disposed in the middle of the first end edge of the bottom plate 21, and the second notch 225 is correspondingly disposed in the middle of the front baffle 221. In order to correspond to the position of the fixed joint 15 on the liquid container 12, by disposing the first notch 211 and the second notch 225 in the middle position, it can directly correspond to the fixed joint 15, reducing the complexity of the process and facilitating the derivation of the ink in the liquid container 12.

[0079] On the other hand, referring to Figure 1 , the present application also provides a printer, including a mounting portion 50 and an assembly. The assembly includes a housing 20 and the above-mentioned liquid containing device. The liquid containing device is connected to the housing 20, and the housing 20 is connected to the mounting portion 50; the mounting portion 50 includes an electrical connection portion 52. The liquid containing device is provided with a chip 14. When the housing 20 is connected to the mounting portion 50, the chip 14 is electrically connected to the electrical connection portion 52. It should be emphasized that when the above-mentioned assembly is installed in the printer, the housing 20 is directly connected to the mounting portion 50 of the printer, and the liquid containing device is installed on the mounting portion 50 of the printer by being directly connected to the housing 20, and the liquid containing device itself is not connected to the mounting portion 50 of the printer.

[0080] This embodiment provides a liquid containing device 10, which is detachably installed in the housing 20; the housing 20 includes a bottom plate 21, the liquid containing device 10 is located on the bottom plate 21, the first end edge of the bottom plate 21 has a first notch 211, the liquid containing device includes a liquid container 12 and a connecting member 11. The connecting member 11 is fixed to one end of the liquid container 12 close to the first notch 211, and the connecting member 11 is provided with a chip 14 at a position close to the first end edge of the bottom plate 21; the connecting member 11 includes a body and a limiting member 152, and the limiting member 152 is located on the side of the body close to the bottom plate 21; the limiting member 152 includes a penetrating portion 152a and a engaging portion 152b. The top end of the penetrating portion 152a is fixedly connected to the body, the bottom end of the penetrating portion 152a extends from the first notch 211 to the lower side of the bottom plate 21, and the engaging portion 152b is disposed at the bottom end of the penetrating portion 152a. The projection of the engaging portion 152b on the bottom plate 21 at least partially falls outside the first notch 211. The liquid containing device 10 provided by the present application has a simple structure and can ensure relative fixation with the mounting portion of the printer, thereby reducing the structural complexity of the liquid containing device.

[0081] Embodiment Three

[0082] Embodiment Three provided by the present application is a further improvement of the above Embodiment Two. The overall structures of the two are relatively similar. The differences from Embodiment Two will be introduced in detail below.

[0083] As Figure 10As shown, the projection of the connecting member 11 on the bottom plate 21 can be set as a trapezoid with the bottom side parallel to the front baffle 221, that is, the length of the connecting member 11 on the side facing the front baffle 221 is greater than the length of the connecting member 11 on the side facing away from the front baffle 221. The side of the connecting member 11 facing away from the front baffle 221 is the side close to the liquid container 12. Specifically, the side of the connecting member 11 close to the front baffle 221 is wider and can be set in size to abut against the side baffle 223, so as to ensure the installation stability, and its two sides do not contact the convex portion 23, and there will be no interference with the convex portion 23 during the installation process, which can improve the convenience of the installation process. In addition, the width of the part of the connecting member 11 far from the front baffle 221 is significantly narrowed, and its two sides can serve as the acting points for the user to grasp and place the liquid container 12, and the liquid container 12 can be exempted from setting a handle member.

[0084] In addition, as shown in Figures 11 - 12 a guiding groove 214 cooperating with the locking portion 54 is provided at the bottom of the bottom plate 21. A guiding inclined surface 115 is provided on the bottom of the connecting member 11 on the side close to the front baffle 221 (the guiding inclined surface 115 is also provided in the second embodiment, and the local contour of the corresponding part of the connecting member can be referred to Figure 8 for understanding). There is a gap between the connecting member 11 and the wedge-shaped convex portion 213 at the guiding inclined surface 115. In this embodiment, a plurality of ribs are densely arranged at the bottom of the connecting member 11. The bottom surfaces of the ribs on the side of the bottom of the connecting member 11 close to the front baffle 221 are inclined and flush. Therefore, the guiding inclined surface 115 is actually the bottom surfaces of these ribs and can be understood as a set of discontinuous narrow surfaces. Figures 13 - 14 Schematically shows the specific structure of the limiting member 152 and the specific connection relationship between the passing-out portion and the engaging portion in this embodiment.

[0085] When the liquid container 12 is installed, the end of the connecting member 11 provided with the liquid outlet portion 111 can be first abutted against the front baffle 221 and abutted against the front baffle 221 at the guiding inclined surface 115. The liquid container 12 can then slide into the interior of the housing 20 along the guiding inclined surface and be clamped with the bottom plate 21. The guiding inclined surface can ensure that the sliding assembly process of the liquid container 12 is smooth without jamming.

[0086] In addition, the housing 20 corresponding to this embodiment is also different in structure from the second embodiment. Specifically, the two convex portions 23 on its bottom plate 21 are provided at both ends of the bottom plate 21 in the X direction, and the outside of the convex portion 23 is fused with the side baffle 223.

[0087] Embodiment 4

[0088] See Figures 15 - 16, the housing 20 used in this embodiment is exactly the same as that in the first embodiment. The main difference between the liquid containing device 10 involved and the comparative document 1 lies in the restricting member. In this embodiment, the restricting member 153 is provided on one side of the connecting member 11 close to the rear baffle 222. In the X-axis direction, on each side of the restricting member 153 away from the connecting member 11, it abuts against a side edge 224 at the cut-off surface 227. The distance from the cut-off surface 227 to the front baffle 221 is greater than the distance from the protrusion 23 to the front baffle 221. The connecting member 11 includes a front portion 113 close to the front baffle 221 and a transition portion 114 close to the rear baffle 222. The liquid outlet portion 111 and the chip 14 are located on the front portion 113, and the restricting member 153 is provided on one side of the transition portion 114 close to the rear baffle 222. In the X-axis direction, the transition portion 114 is located between the two protrusions 23, the length of the transition portion 114 is less than the length of the front portion 113, and the length of the restricting member 153 is greater than the length of the front portion 113.

[0089] Both ends of the restricting member 153 abut against the corresponding side baffle 223, at least part of the bottom surface of the restricting member 153 fits with the upper surface of the bottom plate 21, and the thickness of the restricting member 153 is less than the thickness of the connecting member 11. A recessed portion 153a for avoiding the liquid container 12 is centrally provided on the restricting member 153. The height of the recessed portion 153a is less than or equal to the thickness of the restricting member 153, and the length of the recessed portion 153a in the X-axis direction is less than the side length of the side of the transition portion 114 close to the rear baffle 222. In addition, a guiding inclined surface 115 is also provided on one side of the bottom of the connecting member 11 close to the front baffle 221. Introducing the recessed portion 153a can reduce the interference of the restricting member 153 on the liquid container 12. In this embodiment, the height of the recessed portion 153a in the Z-axis direction is equal to the thickness of the restricting member 153 in the Z-axis direction, and the restricting member 153 is disconnected at the recessed portion 153a, which can effectively avoid the liquid container 12. It should be noted that in this embodiment, the aforementioned lengths all refer to the dimensions in the X-axis direction, and the thickness or height all refer to the dimensions in the Z-axis direction.

[0090] The outer ends of the liquid outlet portions 111 and the two ends of the restricting member 153 form a triangular arrangement and are all directly connected to the outer frame 22, which can ensure the stable assembly of the whole liquid containing device 10 in the housing 20, and further improve the contact stability between the chip 14 and the printer electrical connection portion 52. The liquid outlet portion 111 can also play a role of guiding and positioning during the installation process. The force received by the liquid containing device 10 can act on the whole outer frame 22, which can prevent the stress of the housing 20 from being overly concentrated and effectively inhibit the structural damage and deterioration of the housing 20 at the connection part with the liquid containing device 10.

[0091] Embodiment Five

[0092] See Figures 17 - 21, this embodiment provides an ink cartridge that can be directly loaded into a printer. The ink cartridge includes a cartridge body 30. Ink can be stored inside the cartridge body 30. The cartridge body 30 has a relatively arranged cartridge bottom surface 31 and a cartridge top surface 32. The cartridge bottom surface 31 is the end face of the cartridge body 30 in the +Z direction, and the cartridge top surface 32 is the end face of the cartridge body 30 in the -Z direction. The end face of the cartridge body 30 in the +Y direction is the cartridge front face 33.

[0093] The cartridge bottom surface 31 and the cartridge top surface 32 are the two largest outer surfaces of the cartridge body 30. In this embodiment, a guiding groove 311 that cooperates with a locking portion 54 on the printer mounting portion 50 is provided at the +Y end of the cartridge body 30 on the cartridge bottom surface 31 to prevent the ink cartridge from detaching from the printer mounting portion 50.

[0094] The cartridge body 30 further includes: a liquid outlet portion 111 provided on the cartridge front face 33; an electrical connection portion 35 provided at the intersection of the cartridge front face 33 and the cartridge top surface 32. The electrical connection portion 35 is provided with a chip that contacts a contact pin inside the printer mounting portion 50. In the X-axis direction, the electrical connection portion 35 and the guiding groove 311 at least partially overlap.

[0095] The cartridge body 30 includes a bottom shell and a cover member 36 that can be separated in the vertical direction. The bottom shell includes a rectangular bottom plate. The cartridge bottom surface 31 is the outer surface of the bottom plate. A joint area is provided at the +Y end of the bottom plate. The guiding groove 311 is located in the joint area. A ink storage area is provided at the -Y end of the bottom plate. Connection blocks are provided on the top surface of the bottom plate in the joint area. The liquid outlet portion 111 and the electrical connection portion 35 are provided on the connection blocks.

[0096] The cartridge bottom surface 31 is provided with guide rail ribs 312 extending in the Y-axis direction at least in the area corresponding to the ink storage area. The guide rail ribs 312 can cooperate with the groove-shaped guide rails on the bottom wall of the printer ink cartridge chamber to guide the advancement and installation of the ink cartridge.

[0097] The bottom plate is provided with a closed peripheral wall 43 and an inner peripheral wall 44 at the edge of the ink storage area. There is a gap portion 45 between the peripheral wall 43 and the inner peripheral wall 44. The cover member 36 is provided with a plug-in portion 361 that cooperates with the gap portion 45.

[0098] The cover member 36 is a rigid member, including a cover plate 362 that covers the entire ink storage area and at least part of the joint area. A plurality of buckle members 37 are provided in the area corresponding to the joint area on the cover plate 362. The connection block 42 is provided with a receiving portion 46 that cooperates with the buckle members. The buckle member 37 includes an insertion plate 371 vertically provided on the bottom surface of the cover plate 362. A clamping protrusion 372 is provided at the lower edge of the side surface of the insertion plate 371. The receiving portion 46 includes a receiving hole 461 on the connection block that cooperates with the insertion plate 371. The receiving portion 46 further includes a clamping rib 462 provided on the inner wall of the receiving hole 461 that cooperates with the clamping protrusion 372.

[0099] The receiving part 46 includes two end receiving parts 46a and at least one intermediate receiving part 46b. In the X-axis direction, the two end receiving parts 46a are located at both ends of the connection block, the intermediate receiving part 46b is located between the two end receiving parts 46a, at least one intermediate receiving part 46b is located between the liquid outlet part 111 and the electrical connection part 35, and the distance from at least one intermediate receiving part 46b to the outer peripheral wall 43 is less than the distance from the end receiving part 46a to the outer peripheral wall 43.

[0100] The inner peripheral wall 44 has a rounded transition with the lower edge of the inner wall and the bottom plate 41, the projection of the outer peripheral wall 43 on the bottom plate is rectangular, and the gap part 45 is located at the four corners inside the outer peripheral wall 43.

[0101] The connection block is provided with abutting parts 47 on both sides of the liquid outlet part 111, and the cover plate 362 is provided with abutting posts 38 that cooperate with the abutting parts 47 in the area corresponding to the joint area. The above ink cartridge can be used as a carrier for the ink pack, and the ink pack is only used to store ink and does not need to be provided with functional structures thereon.

[0102] The above ink cartridge can also directly store ink inside. Specifically, the closed space separated by the ink storage area of the bottom plate, the inner peripheral wall 44 and the cover plate 362 is used as the ink storage cavity 48. An air pressure balancing part 481 and an ink outlet valve 482 communicating with the outside are provided in the ink storage cavity 48.

[0103] A liquid supply channel communicating with the ink storage cavity 48 is provided in the liquid outlet part 111. The ink outlet valve 482 includes a valve seat 482a provided in the liquid supply channel and a spherical valve core 482b. The valve core 482b is located above the valve seat 482a. The valve core 482b can be made of a light material or provided with a cavity inside to ensure that its density is less than the density of the liquid stored in the ink cartridge. An ink outlet hole 482c is provided in the valve seat 482a along the Z-axis direction, and a sealing groove 482d that cooperates with the bottom of the valve core 482b is provided around the ink outlet hole 482c at the top of the valve seat 482a. When there is liquid in the liquid supply channel, the valve core 482b floats up and separates from the valve seat 482a, and the ink outlet valve 482 opens. After the injection tube 51 is connected to the liquid supply channel, liquid can be sucked. When the liquid level in the ink cartridge is too low and no liquid enters the liquid supply channel, the bottom of the valve core 482b enters the sealing groove 482d and closes the ink outlet hole 482c, and the ink outlet valve 482 closes. The injection tube 51 cannot suck liquid through the liquid supply channel. Therefore, the control system of the printer can judge whether the ink cartridge is emptied by detecting the magnitude of the suction force.

[0104] The air pressure balancing part 481 is provided with a circuitous air guide channel 481a. The air guide channel 481a is used to balance the air pressure inside and outside the ink cartridge. The two ends of the air guide channel 481a are respectively communicated with the ink storage cavity 48 and the air inlet hole 481b on the side wall of the cartridge body 30. The air pressure balancing part 481 is used to prevent the liquid in the ink storage cavity 48 from leaking out through the air inlet hole 481b when the air inlet hole 481b is opened.

[0105] A plurality of partition plates 483 are further provided at intervals in the ink storage chamber 48. The partition plates 483 are used to divide the ink storage chamber 48 into a plurality of chambers. Each chamber is communicated through a notch 483a at the bottom of the partition plate 483. Both ends of the partition plate 483 are integrally connected to the inner surrounding wall 44, and the lower edge of the partition plate 483 is integrally connected to the bottom plate.

[0106] The above ink cartridge is convenient to install, and the connection structure layout between the bottom shell and the cover member 36 is reasonable, which can ensure the structural stability of the ink cartridge at positions such as the liquid outlet part 111 and the electrical connection part 35 and is convenient for disassembly and assembly. The above ink cartridge can be implemented as an integrated ink cartridge solution. In this implementation mode, it can be compatible with the tray-type housing-liquid container ink cartridge solution, and can store more ink compared with the tray-type housing-liquid container ink cartridge solution with the same installation volume.
