DETAILED DESCRIPTION

[0068] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0069] It should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0070] In the present utility model, unless otherwise clearly defined and limited, terms such as "installed", "connected", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or communicable with each other; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model may be understood according to specific circumstances.

[0071] In the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature is at a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature is at a lower horizontal height than the second feature.

[0072] In the above description, the descriptions referring to terms such as "one embodiment", "some embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0073] In the related art, there are problems such as interference, jamming during the installation of the consumable cartridge into the machine, and the inability to install the cartridge in place, and even the guiding rib may be damaged, resulting in a poor user experience. The inventor found that the reason for this problem is that when the user installs the consumable cartridge into the printing device, the operation is not standardized, that is, the inner enclosure wall 150a of the consumable cartridge is not accurately aligned with the guiding rib 1003 provided on the frame 1120 of the installation unit 1000, which may cause the installation position or posture of the consumable cartridge to shift or change, leading to problems such as interference, jamming during the installation of the consumable cartridge into the machine, and the inability to install the cartridge in place, and even the guiding rib may be damaged, resulting in a poor user experience.

[0074] To solve the above problems, an embodiment of the present utility model provides a consumable cartridge. The guided portion can be closer to the front wall relative to the inner enclosure wall in the length direction of the consumable cartridge. When installing the consumable cartridge into the machine, there is no need to align the guiding rib in the printing device with the inner enclosure wall, which can effectively avoid problems such as interference, jamming during the installation of the consumable cartridge into the machine, and the inability to install the cartridge in place, and even the guiding rib may be damaged.

[0075] It is also possible to cut off the entire inner enclosure wall. When installing the consumable cartridge into the machine, there is no need to accurately align the guiding rib in the printing device with the inner enclosure wall of the spacer portion, which can effectively avoid problems such as interference, jamming during the installation of the consumable cartridge into the machine, and the inability to install the cartridge in place, and even the guiding rib may be damaged.

[0076] The following will specifically describe the consumable cartridge provided by the embodiment of the present utility model in conjunction with specific embodiments.

[0077] Such as Figure 2 And Figure 3As shown, a consumable cartridge provided by the present utility model is detachably installed in the installation unit 1000 of a printing device. Ink is stored in the consumable cartridge. During printing, the ink is output to the ink supply part in the installation part 1100, and the ink supply part supplies the ink to the print head. The print head sprays the ink onto the printing medium to form characters or patterns. The installation unit 1000 can reciprocate along the guide rail to achieve printing. As Figure 3 shown, the installation unit 1000 includes a main body 1001 and a frame 1002. The frame 1002 is installed on the main body 1001. The installation unit 1000 includes a plurality of installation parts 1100. Consumable cartridges containing different inks are respectively loaded into the corresponding installation parts 1100. Guide ribs 1003 are provided on the frame 1002 at intervals, and adjacent installation parts 1100 are separated by the guide ribs 1003.

[0078] An interface unit 1120 is provided on the rear wall surface 1101 of each installation part 1100. The interface unit 1120 includes an ink supply part 1121 and an inflation part 1122. In the first direction (+Z-axis direction), the inflation part 1122 is farther from the bottom wall surface 1102 of the installation part 1100 than the ink supply part 1121. The installation part 1100 includes a deformation part 1123, and the deformation part 1123 is arranged around the inflation part 1122. The installation part 1100 further includes a guiding part 1140. The guiding part 1140 and the movable shaft 1141 are arranged on the bottom wall surface 1102 and can swing a certain angle around the movable shaft 1141. A guiding protrusion 1142 is provided at one end of the guiding part 1140 away from the movable shaft 1141, and the guiding protrusion 1142 is configured as a sheet-like long strip structure. A first fitting part 1150 is further provided on the bottom wall surface 1102 of each installation part 1100, and a second fitting part 1160 is further provided on the frame 1002. Among them, one of the plurality of installation parts 1100 is used to accommodate a consumable cartridge for black ink, and a third fitting part 1170 is further provided at a position adjacent to the first fitting part 1150 in this installation part 1100.

[0079] A contact pin assembly 1130 is further provided on the rear wall surface 1101 of each installation part 1100. In the height direction (i.e., Z-axis direction) of the installation part 1100, the position where the contact pin assembly 1130 is located is higher than the position where the interface unit 1120 is located. The contact pin assembly 1130 includes a plurality of contact pins 1131, and a guiding inclined surface 1132 is provided at a position adjacent to the contact pins 1131 on the contact pin assembly 1130.

[0080] For a better description of the consumable cartridge, as Figure 4Establish a coordinate system: The width direction of the consumable cartridge 1 is the X-axis direction, the length direction of the consumable cartridge 1 is the Y-axis direction, and the height direction of the consumable cartridge 1 is the Z-axis direction. Among them, the X-axis, Y-axis, and Z-axis are perpendicular to each other. In this example, the first direction is the direction indicated by the -Z axis, the second direction is the direction indicated by the +Y axis, and the third direction is the direction indicated by the +X axis. The included angles between the first direction, the second direction, and the third direction can be 90°. In other possible implementation manners, the included angle between the first direction and the second direction can be 80° to 100°, for example, it can be 80°, 85°, 90°, 95°, or 100°.

[0081] As Figure 4 and Figure 5 shown, the consumable cartridge 1 includes a body, and the body is formed by enclosing multiple walls. Ink is stored in the body. In the first direction, the consumable cartridge has a bottom wall 10 and a top wall 70. In the second direction, the consumable cartridge has a front wall 20 and a rear wall 50. In the third direction, the consumable cartridge has two relatively arranged side walls 60. The front wall 20 has a fluid interface portion 30 (see Figure 1 ), and the fluid interface portion 30 includes an ink outlet 32 and an inflation hole 31. In the first direction, the ink outlet 32 is closer to the bottom wall 10 than the inflation hole 31. When the consumable cartridge 1 is installed in the corresponding installation portion 1100, the ink outlet 32 is engaged with the ink supply portion 1121, the inflation hole 31 is engaged with the inflation portion 1122, and the deformation member 1123 abuts against the surface of the wall where the inflation hole 31 of the consumable cartridge is located. The consumable cartridge 1 further includes a cartridge installation portion 80, and the cartridge installation portion 80 is provided on the notch portion 21 provided on the consumable cartridge body. In the second direction, the notch portion 21 is configured to form a depression from the front wall 20 toward a direction away from the front wall 20. The electrical interface component 40 is provided on the cartridge installation portion 80, and the cartridge installation portion 80 can be provided on the notch portion 21 in a fixed or detachable manner. A guiding inclined surface 1311 is provided at the edge of the cartridge installation portion 80. When the consumable cartridge 1 is installed in the printing device, the guiding inclined surface 1311 provided on the cartridge installation portion 80 is guided by the guiding inclined surface 1132 in the touch pin assembly 1130, so that the electrical interface component 40 is electrically connected to the touch pin 1131 of the touch pin assembly 1130.

[0082] Example 1:

[0083] As Figure 6As shown, the bottom wall 10 of the consumable cartridge 1 is configured to include a first region 100. An air separation portion 110, a guided portion 120, and a non-air separation portion 130 are provided in the first region 100. In the second direction, the non-air separation portion 130, the guided portion 120, and the air separation portion 110 are arranged in sequence, and the guided portion 120 is located between the non-air separation portion 130 and the air separation portion 110. Compared with the guided portion 120, the non-air separation portion 130 is located at a position in the first region 100 that is farther from the ink outlet 32, and the air separation portion 110 is located at a position in the first region 100 that is closer to the ink outlet 32.

[0084] The bottom wall 10 further includes a second region 200. In the third direction, the first region 100 and the second region 200 are adjacently arranged, and in the second direction, the lengths of the first region 100 and the second region 200 are the same. An outer peripheral retaining wall 160 is further provided on the bottom wall 10. In the first direction, the outer peripheral retaining wall 160 protrudes from the bottom wall 10, and the outer peripheral retaining wall 160 is configured to partially surround the outside of the first region 100 and the second region 200. In the first direction, the second region 200 is higher than the non-air separation portion 130.

[0085] It should be noted that in the third direction, the projection of the air separation portion 110 and a part of the second region 200 close to the front wall 20 at least partially overlap, that is, in the first direction, the height of at least a part of the surface of the air separation portion 110 is slightly higher than or equal to the height of the surface of a part of the second region 200 close to the front wall 20. This effectively avoids the situation in the prior art where the surface of a part of the second region 200 close to the front wall 20 of the consumable cartridge is higher than the air separation portion 110 in the first region 100, thereby effectively avoiding problems such as installation position deviation, resulting in interference, jamming, and failure to be installed in place during the process of installing the consumable cartridge into the printing device due to the second region 200 of the bottom wall of the consumable cartridge being higher than the first region 100.

[0086] It should also be pointed out that the height in this application refers to the height relative to the top wall 70 in the first direction. For example, in the first direction, the height of the second region 200 refers to the height of the second region 200 relative to the top wall 70 in the first direction.

[0087] There is a first groove 140 between the first region 100 and the second region 200. Specifically, the first region 100 and the second region 200 are not connected, and the first region 100 and the second region 200 are separated by the first groove 140.

[0088] In the third direction, the first groove 140 and the guided portion 120 are at least partially connected.

[0089] The inner retaining wall 150 may be formed in the second region 200. Specifically, the inner retaining wall 150 may be formed on a part of the side wall of the second region 200 facing the first region 100. The inner retaining wall 150 is configured to have the concave-convex portions 210. The concave-convex portions 210 include a protruding portion facing the first region 100 and a recessed portion facing the second region 200, and the protruding portion and the recessed portion are alternately arranged in the second direction. In other embodiments, the inner retaining wall 150 may also be formed on a part of the side wall of the first region (100) facing the second region (200). Or, the inner retaining wall 150 may further be formed on a part of the side wall of the first region (100) facing the second region (200) and on a part of the side wall of the second region 200 facing the first region 100.

[0090] In the third direction, the inner retaining wall 150 and the guided portion 120 are arranged at intervals.

[0091] In the second direction, there is a spacing between the inner retaining wall 150 and the front wall 20, and the inner retaining wall 150 is configured to extend toward the rear wall 50.

[0092] There is an opening 141 connected to the first groove 140 between the first region 100 and the second region 200, and the opening 141 is closer to the front wall 20 than the first groove 140 in the second direction. Through the opening 141, there can be a spacing between the inner retaining wall 150 and the front wall 20.

[0093] The shape of the opening 141 is preferably a flared shape. One end of the opening 141 away from the first groove 140 is the first end, and the first end is connected to the front wall 20. One end of the opening 141 close to the first groove 140 is the second end, and the second end is connected to the first groove 140. The width of the opening 141 gradually decreases in the direction from the first end to the second end. With such a setting, the width of the opening 141 can be greater than the width of the first groove 140. During the process of loading the consumable cartridge into the printing device, since the width of the opening 141 is greater than the width of the first groove 140, it is not necessary to align the guiding rib 1003 in the printing device with the first groove 140, and the guiding rib 1003 will not interfere with the consumable cartridge, thereby improving the convenience, operability, adaptability and user experience of the installation of the consumable cartridge and the printing device.

[0094] It should be noted that the shape of the opening 141 may also be other shapes such as a quadrilateral or a sector, so as to achieve the purpose that during the process of loading the consumable cartridge into the installation unit, it is not necessary to align the guiding rib 1003 in the printing device with the first groove 140, so that the guiding rib 1003 does not interfere with the consumable cartridge.

[0095] Such as Figure 7As shown, the side wall of the first region 100 facing the opening 141 is the first flange wall 1411. The first flange wall 1411 is located on a partial side wall of the first region 100 facing the second region 200, and the first flange wall 1411 is connected to the front wall 20. During the process of loading the consumable cartridge into the printing device, the first flange wall 1411 can avoid the guiding rib 1003 to prevent interference between the guiding rib 1003 and the consumable cartridge.

[0096] The shape of the first flange wall 1411 is arc-shaped.

[0097] As Figure 6 、 Figure 7 and Figure 8 shown, the guided portion 120 at least includes an entrance portion 121, a locking path 122, a converging path 125, and an unlocking path 126. The converging path 125 is respectively connected to the locking path 122 and the unlocking path 126.

[0098] The guided portion 120 further includes a guiding protrusion. The guiding protrusion is used to define the path of the guiding protrusion 1142. The guiding protrusion can be located at a position of the guided portion 120 facing the locking path 122 and the entrance portion 121. In other embodiments, the guiding protrusion can also be located at a position of the guided portion 120 facing the locking path 122. Or, the guiding protrusion can also be located at a position of the guided portion 120 facing the entrance portion 121.

[0099] The guiding protrusion includes a first guiding protrusion 1213 and a second guiding protrusion 123.

[0100] In the third direction, one end of the entrance portion 121 has a bump 1211, the other end of the entrance portion 121 has a first guiding protrusion 1213, and there is a first notch 1212 between the bump 1211 and the first guiding protrusion 1213. The first notch 1212 facilitates the guiding protrusion 1142 to enter the locking path 122. In the third direction, the locking path 122 and the unlocking path 126 are arranged oppositely. In the opposite direction of the second direction, both the locking path 122 and the unlocking path 126 are configured such that one end starts from the entrance portion 121 and the other end extends towards the converging path 125.

[0101] The first guiding protrusion 1213 includes a first guiding surface 121a and a second guiding surface 121b. The first guiding surface 121a intersects with the second guiding surface 121b. The first guiding surface 121a is inclined towards the second region 200 in the second direction, and the second guiding surface 121b is inclined towards the locking path 122 in the second direction.

[0102] The second guiding protrusion 123 is spaced apart from the first guiding protrusion 1213. The first guiding protrusion 1213 is closer to the front wall 20 than the second guiding protrusion 123 in the second direction.

[0103] The second guiding protrusion 123 includes a guiding convex end 123a and a third guiding surface 123b. The guiding convex end 123a faces the second region 200, and the third guiding surface 123b is inclined towards the locking path 122 along the second direction.

[0104] In the third direction, the guiding convex end 123a is closer to the second region 200 than the third guiding surface 123b.

[0105] The locking path 122 is further provided with a locking portion 124. The locking portion 124 is located between the locking path 122 and the unlocking path 126. The locking portion 124 includes a first surface 1241, a locking surface 1242, and a second surface 1243. The first surface 1241, the locking surface 1242, and the second surface 1243 enclose to form the locking portion 124. Among them, the surface of the locking portion 124 facing the locking path 122 is the first surface 1241, the surface facing the unlocking path 126 is the second surface 1243, and the surface facing the intersection path 125 is the locking surface 1242.

[0106] The intersection path 125 is further provided with a clamping portion 127. In this embodiment, the number of the clamping portions 127 is two, and the two clamping portions 127 are located on one side of the guided portion 120 close to the non-air separation portion 130 at intervals. In the direction opposite to the second direction, the clamping portion 127 is farther from the inlet portion 121 than the locking portion 124.

[0107] The guided portion 120 includes a boss 128, and the boss 128 is located between the two clamping portions 127. In this embodiment, the clamping portion 127 is configured as a slot structure, and the clamping portion 127 can also be configured as other structures to adapt to the structures of the guided portion 120 and the guiding portion 1140 in the printing device. The boss 128 has a first inclined surface 1281, and the first inclined surface 1281 is inclined towards one of the clamping portions 127. The outer side of the clamping portion 127 close to the second region 200 further has a second inclined surface 1271. In this embodiment, by providing the second guiding protrusion 123 at a position adjacent to the locking portion 124 in the locking path 122, it is used to limit the movement path of the guiding protrusion 1142 in the locking path 122 and correct the posture of the consumable cartridge during the installation process, so that the guiding protrusion 1142 can move along the correct installation path to contact the second inclined surface 1271 and be guided into the corresponding clamping portion 127 through the second inclined surface 1271, improving the operability and accuracy of the consumable cartridge installation process.

[0108] The guided part 120 includes locking paths 122 and unlocking paths 126 located on both sides of the locking part 124, and a converging path 125 located on the front side of the locking part 124. In the third direction, the locking path 122 is located on the side close to the second area 200, the unlocking path 126 is located on the side far from the second area 200, and the converging path 125 connects the locking path 122 and the unlocking path 126.

[0109] The process of properly installing the consumable cartridge 1 into the printing device is as follows: An external force in the opposite direction of the second direction is applied to the consumable cartridge 1, and it enters the installation part 1100 along the second direction. When the guiding protrusion 1142 in the guiding part 1140 reaches the first position of the installation part 1100 after passing through the empty space part 110, the guiding protrusion 1142 reaches the entrance part 121 of the guided part 120 and enters the guided part 120 through the first notch 1212 of the entrance part 121. It should be noted that during the whole process, the guiding protrusion 1142 does not contact the empty space part 110, and the guiding rib 1003 enters the first groove 140 from the opening 141 without contacting the first groove 140 and the opening 141. When the guiding protrusion 1142 enters the guided part 120 through the first notch 1212 at the entrance part 121, the guiding part 1140 swings a certain angle around the movable shaft 1141, so that the guiding protrusion 1142 enters the locking path 122. The guiding protrusion 1142 moves along the locking path 122 to between the second guiding protrusion 123 and the locking part 124. The second guiding protrusion 123 drives the guiding protrusion 1142 to deflect towards the locking part 124 and makes it move along the first surface 1241 of the locking part 124. When the guiding protrusion 1142 moves out of contact with the surface of the first surface 1241 and enters the converging path 125, the consumable cartridge moves to the second position in the installation part 1100. At this time, the guided inclined surface 1311 of the cartridge installation part 80 of the chip assembly contacts the guiding inclined surface 1132 in the contact pin assembly 1130, and the guiding inclined surface 1132 is used to continue guiding the consumable cartridge towards the third position of the installation part 1100. As the consumable cartridge continues to move towards the third position, the electrical interface component 40 is electrically connected to the contact pin 1131 of the contact pin assembly 1130. When the consumable cartridge moves to the third position, the ink outlet 32 and the inflation hole 31 of the consumable cartridge 1 are respectively pre-joined with the ink supply part 1121 and the inflation part 1122 in the installation part 1100, and the deformation part 1123 arranged around the periphery of the inflation part 1122 contacts the front wall 20 of the consumable cartridge and starts to deform.

[0110] As the consumable cartridge continues to move from the third position towards the target installation position, the guiding protrusion 1142 moves to contact the second inclined surface 1271 located in the intersection path 125 and is guided by the second inclined surface 1271 into the engaging portion 127 adjacent to the second region 200. At this time, the deformation member 1123 disposed around the ink supply portion 1121 has the largest amount of deformation. Subsequently, the external force acting on the consumable cartridge 1 is withdrawn. The consumable cartridge 1 moves in the second direction under the action of the restoring deformation force of the deformation member 1123. The guiding protrusion 1142 disengages from the engaging portion 127, falls onto the locking surface 1242, and slides along the inclined surface on the locking surface 1242, and finally falls into the recess 1244, thereby completing the installation of the consumable cartridge 1. During the whole process, the guiding rib 1003 does not contact the first groove 140 and the space portion 151. When the consumable cartridge 1 is completely installed in the installation portion 1100, the guiding rib 1003 is located in the first groove 140, and a part of the peripheral retaining wall 160 supports on the second adapter portion 1160 and the third adapter portion 1170. In the first direction, the non-contact portion 110 is located above the first adapter portion 1150 and does not contact it. A part of the non-non-contact portion 130 and the second region 200 is located above the second adapter portion 1160 and does not contact it. The non-contact portion 110 and the other part of the second region 200 are located above the third adapter portion 1170 and do not contact it.

[0111] Case 1 of the non-standard installation of the consumable cartridge 1 into the printing device: An external force in the opposite direction of the second direction is applied to the consumable cartridge 1, and it enters the installation portion 1100 along the second direction. The guiding protrusion 1142 in the guiding portion 1140 deviates from the entrance portion 121 of the guided portion 120, that is, it does not enter the guided portion 120 from the first notch 1212 of the entrance portion 121. The guiding protrusion 1142 moves along the first guiding surface 121a of the first guiding protrusion 1213 into the second guiding surface 121b, and re-enters the locking path 122 along the second guiding surface 121b. The guiding protrusion 1142 moves along the locking path 122 between the second guiding protrusion 123 and the locking portion 124. The second guiding protrusion 123 drives the guiding protrusion 1142 to deviate towards the locking portion 124 and makes it move along the first surface 1241 of the locking portion 124. The remaining installation process of the consumable cartridge 1 is the same as the standard installation process of the consumable cartridge 1, and will not be specifically described here.

[0112] Improper installation of the consumable cartridge 1 into the printing device, case 2: An external force in the opposite direction of the second direction is applied to the consumable cartridge 1, and it enters the installation part 1100 along the second direction. The guiding protrusion 1142 in the guiding part 1140 deviates from the entrance part 121 of the guided part 120, that is, it does not enter the guided part 120 from the first notch 1212 of the entrance part 121. The guiding protrusion 1142 moves along the first guiding surface 121a of the first guiding protrusion 1213 to the guiding convex end 123a of the second guiding protrusion 123. As the consumable cartridge continues to move, the guiding protrusion 1142 moves from the guiding convex end 123a to the third guiding surface 123b and re-enters the locking path 122 along the third guiding surface 123b. The guiding protrusion 1142 moves to contact the second inclined surface 1271 located in the intersection path 125 and is guided by the second inclined surface 1271 into the clamping part 127 adjacent to the second area 200. The remaining installation process of the consumable cartridge 1 is the same as the standard installation process of the consumable cartridge 1, and will not be specifically described here.

[0113] As the consumable cartridge 1 is used, the ink stored in the consumable cartridge 1 is completely exhausted, and the user needs to remove the consumable cartridge 1 from the installation part 1100. Specifically: An acting force in the second direction is applied to the consumable cartridge 1, and the guiding protrusion 1142 in the guiding part 1140 slides from the depression 1244 along the other inclined surface of the locking surface 1242 to disengage from the locking surface 1242 and enters the intersection path 125. As the consumable cartridge 1 continues to displace, the rear guiding protrusion 1142 contacts the boss 128 located in the intersection path 125 and displaces along the first inclined surface 1281 of the boss 128 and enters another clamping part 127 away from the second area 200. At this time, the deformable part 1123 arranged around the periphery of the ink supply part 1121 contacts the front wall of the consumable cartridge 1 and is compressed. At this time, the external force is withdrawn and the consumable cartridge 1 is no longer pressed. The consumable cartridge displaces in the opposite direction of the second direction under the action of the restoring deformation force of the deformable part 1123, so that the guiding protrusion 1142 disengages from another clamping part 127, enters the unlocking path 126 and contacts the second surface 1243 of the locking part 124, and moves along the second surface 1243 to disengage from the unlocking path 126 and enter the entrance part 121. The electrical interface component 40 is disconnected from the contact pin 1131, and the guiding rib 1003 disengages from the space part 151. After that, the user can remove the consumable cartridge 1 from the printing device to complete the disassembly of the consumable cartridge 1. During the whole process, the guiding rib 1003 does not contact the first groove 140 and the opening 141.

[0114] Meanwhile, by providing a second guiding protrusion 123 at a position adjacent to the locking portion 124 in the locking path 122, the movement path of the guiding protrusion 1142 in the locking path 122 can be defined, and the posture of the consumable cartridge during installation can be corrected, so that the guiding protrusion 1142 can move along the correct installation path to contact the second inclined surface 1271 and be guided into the corresponding clamping portion 127 by the second inclined surface 1271, improving the operability and accuracy of the consumable cartridge installation process.

[0115] Embodiment 2:

[0116] As Figure 9 shown, the difference between Embodiment 2 and Embodiment 1 is that the length of the consumable cartridge 1 is less than that of the consumable cartridge 1 in Embodiment 1, and there are no first grooves and openings between the first region 100 and the second region 200. In addition, in the first region 100, along the second direction, the non-airspace portion 130 is higher than the second region 200, and the second region 200 has no peripheral retaining wall 160.

[0117] The inner retaining wall 150 is formed in the first region 100. Specifically, the inner retaining wall 150 is formed on a part of the side wall of the first region 100 facing the second region 200.

[0118] In the first direction, the height of the inner retaining wall 150 can be greater than the height of the second region 200. In other embodiments, in the first direction, the height of the inner retaining wall 150 can be greater than the height of the first region 100.

[0119] In the second direction, the inner retaining wall 150 is at least partially connected to the guided portion 120.

[0120] In the third direction, the second region 200 is at least partially connected to the guided portion 120.

[0121] In this embodiment, the rest of the structural design methods and the process of loading or removing the consumable cartridge from the printing device are the same as those in Embodiment 1, and will not be elaborated here.

[0122] Embodiment 3

[0123] As Figure 10 shown, the difference between Embodiment 3 and Embodiment 2 is that the length of the consumable cartridge 1 is greater than that of the consumable cartridge 1 in Embodiment 2, the first region 100 and the second region 200 are connected, and the first region 100 has a second groove 170. The second groove 170 is configured to be recessed in the direction of the housing of the consumable cartridge 1 along the second direction. The second groove 170 is used to avoid the screws provided at the corresponding installation positions in the installation unit 1000 when the consumable cartridge 1 is installed in the installation unit of the printing device.

[0124] The second groove 170 has a second flange wall 170a and a third flange wall 170b in the width direction of the consumable cartridge, and the second flange wall 170a and the third flange wall 170b at least partially overlap in the third direction.

[0125] In the third embodiment, the guided portion 120 is different from that in the first or second embodiment in that, in addition to including an entrance portion 121, a locking path 122, an intersection path 125, and an unlocking path 126, in the third direction, both ends of the entrance portion 121 have bumps 1211, and there is a first notch 1212 between the two bumps 1211. The guided portion 120 in the third embodiment does not have the first guiding protrusion 1213 and the second guiding protrusion 123.

[0126] In this embodiment, the design methods of the remaining structures and the process of loading the consumable cartridge into or removing it from the printing device are the same as those in the second embodiment, and will not be elaborated here.

[0127] Embodiment Four

[0128] As Figure 11 shown, the difference between the fourth embodiment and the third embodiment is that there is no second region 200, and peripheral retaining walls 160 are provided on at least three side walls of the first region 100. The second groove 170 has a second flange wall 170a in the width direction of the consumable cartridge.

[0129] In this embodiment, the design methods of the remaining structures and the process of loading the consumable cartridge into or removing it from the printing device are the same as those in the third embodiment, and will not be elaborated here.

[0130] Embodiment Five

[0131] As Figure 12 shown, the difference between the second embodiment and the first embodiment is that the bottom wall 10 includes at least one inner retaining wall 150, and the inner retaining wall 150 is configured to protrude from the bottom wall 10. In this embodiment, at least one inner retaining wall 150 is provided between the first region 100 and the second region 200.

[0132] In some examples, the number of the inner retaining walls 150 is preferably two. The two inner retaining walls 150 are spaced apart and adjacent, and are respectively disposed on the outside of at least a part of the non-air separation portion 130 in the first region 100 and at least a part of the second region 200 close to the rear wall 50. That is, in the opposite direction of the second direction, each of the two inner retaining walls 150 is located at the rear side of the guided portion 120. That is, the guided portion 120 is closer to the front wall 20 than the inner retaining wall 150 in the second direction.

[0133] A first groove 140 is provided between a first region 100 and a second region 200. A space portion 151 of a semi-closed structure is jointly formed by two inner enclosing walls 150 and a part of a part of an outer enclosing wall 160. A part of the first groove 140 extends into the space portion 151, and another part of the first groove 140 is located outside the space portion 151. It can be understood that the inner enclosing walls 150 are formed on at least a part of the first groove 140. The first groove 140 is configured to extend from a position adjacent to the front wall 20 on the bottom wall 10 to a position close to the rear wall 50. In a second direction, one side of the first groove 140 close to the front wall 20 has an opening 141 connected to the first groove 140. When the consumable cartridge 1 is being loaded into the installation portion of the printing device, a guiding rib 1003 in the printing device enters the first groove 140 from the opening 141. After the consumable cartridge 1 is displaced past a third position in the installation portion 1100 of the printing device, that is, after the fluid interface portion 30 in the consumable cartridge 1 is engaged with the interface unit 1120 in the installation portion 1100, the guiding rib 1003 enters the space portion 151. When the consumable cartridge is being loaded into or removed from the installation portion 1100, the guiding rib 1003 does not contact the first groove 140 or the inner enclosing walls 150. After the consumable cartridge 1 is completely loaded into the installation portion 1100, the guiding rib 1003 is located in the space portion 151.

[0134] In a first direction, the inner enclosing walls 150 are higher than the first region 100, the inner enclosing walls 150 are higher than the second region 200, and the inner enclosing walls 150 are higher than the first groove 140.

[0135] It should be noted that each of the two inner enclosing walls 150 is configured to be connected to an outer enclosing wall 160 that surrounds the bottom wall 10 and is connected to the rear wall 50 at one end, and the other end is away from the rear wall 50. In a direction opposite to the second direction, the distances from the ends of the two inner enclosing walls 150 away from the rear wall 50 to the rear wall 50 are both D1, and the range of D1 is 0 ≤ D1 ≤ 33 mm.

[0136] As Figure 13 shown, one side of the entrance portion 121 of the guided portion 120 has a convex block 1211, and the other side has a second notch 1214. Along a third direction, the second notch 1214 faces the convex block 1211, and the second notch 1214 is close to the second region 200. The second notch 1214 facilitates the guiding protrusion 1142 to enter the locking path 122.

[0137] As Figures 14A - 14EAs shown, the process of installing the consumable box 1 into the printing device is as follows: an external force is applied to the consumable box 1 in the direction opposite to the second direction, and the consumable box 1 enters the installation portion 1100 along the second direction. When the guide protrusion 1142 in the guide portion 1140 passes through the space portion 110 and reaches the first position of the installation portion, the guide protrusion 1142 reaches the entrance portion 121 of the guided portion 120 and enters the guided portion 120 from the entrance portion 121. It should be noted that during the whole process, the guide protrusion 1142 does not contact the partition portion 110, and the guide rib 1003 enters the first groove 140 from the opening 141 and does not contact the first groove 140. After the guide protrusion 1142 enters the guided portion 120 from the notch 1212 at the entrance portion 121, the guide portion 1140 swings a certain angle around the movable shaft 1141, so that the guide protrusion 1142 enters the locking path 122. The guide protrusion 1142 moves along the locking path 122 to between the second guide protrusion 123 and the locking portion 124. The second guide protrusion 123 drives the guide protrusion 1142 to deviate toward the locking portion 124 and displace it along the first surface 1241 of the locking portion 124. When the guide protrusion 1142 moves to separate from the surface of the first surface 1241 and enters the intersection path 125, the consumable box moves to the mounting portion 11 00, at this time, the guided inclined surface 1311 of the box mounting portion 80 of the chip assembly contacts the guiding inclined surface 1132 in the contact pin assembly 1130, and the guiding inclined surface 1132 continues to guide the consumable box to move toward the third position of the mounting portion 1100. As the consumable box continues to move toward the third position, the electrical interface component 40 is electrically connected to the contact pin 1131 of the contact pin assembly 1130. When the consumable box moves to the third position, the ink outlet 32 ​​and the inflation hole 31 of the consumable box 1 are pre-engaged with the ink supply portion 1121 and the inflation portion 1122 in the mounting portion 1100 respectively, and the deformable member 1123 arranged around the periphery of the ink supply portion 1121 contacts the front wall 20 of the consumable box and begins to deform. After the consumable box passes the third position of the mounting portion 1100, the guiding rib 1003 enters the space portion 150, but the guiding rib 1003 does not contact the space portion 151.

[0138] As the consumable cartridge continues to move from the third position towards the target installation position, the guiding protrusion 1142 moves to contact the second inclined surface 1271 located in the intersection path 125 and is guided by the second inclined surface 1271 into the engaging portion 127 adjacent to the second region 200. At this time, the deformation member 1123 provided around the ink supply portion 1121 has the largest amount of deformation. Subsequently, the external force acting on the consumable cartridge 1 is withdrawn. The consumable cartridge 1 is displaced in the second direction under the action of the restoring deformation force of the deformation member 1123. The guiding protrusion 1142 disengages from the engaging portion 127, falls onto the locking surface 1242, and slides along the inclined surface on the locking surface 1242, and finally falls into the recess 1244, thereby completing the installation of the consumable cartridge 1. During the whole process, the guiding rib 1003 does not contact the first groove 140 and the space portion 151. When the consumable cartridge 1 is completely installed in the installation portion 1100, the guiding rib 1003 is located in the first groove 140. A part of the peripheral retaining wall 160 is supported on the second fitting portion 1160 and the third fitting portion 1170. In the first direction, the non-contact portion 110 is located above the first fitting portion 1150 and does not contact it. A part of the non-non-contact portion 130 and the second region 200 is located above the second fitting portion 1160 and does not contact it. The non-contact portion 110 and another part of the second region 200 are located above the third fitting portion 1170 and do not contact it.

[0139] As Figures 15A - 15CAs shown, as the consumable cartridge 1 is used, the ink stored in the consumable cartridge 1 is completely exhausted, and the user needs to remove the consumable cartridge 1 from the installation part 1100. Specifically: apply a force in the second direction to the consumable cartridge 1, and the guiding protrusion 1142 in the guiding part 1140 slides from the recess 1244 along the other inclined surface of the locking surface 1242 to disengage from the locking surface 1242 and enter the intersection path 125. As the consumable cartridge 1 continues to displace, the rear guiding protrusion 1142 contacts the boss 128 located in the intersection path 125, and displaces along the first inclined surface 1281 of the boss 128 and enters another engaging part 127 away from the second area 200. At this time, the deformable part 1123 arranged around the periphery of the ink supply part 1121 contacts the front wall of the consumable cartridge 1 and is compressed. At this time, the external force is removed and the consumable cartridge 1 is no longer pressed. The consumable cartridge displaces in the opposite direction of the second direction under the action of the restoring deformation force of the deformable part 1123, so that the guiding protrusion 1142 disengages from the other engaging part 127, enters the unlocking path 126 and contacts the second surface 1243 of the locking part 124, and moves along the second surface 1243 to disengage from the unlocking path 126 and enter the inlet part 121. The electrical interface component 40 is disconnected from the contact pin 1131, and the guiding rib 1003 disengages from the space part 151. After that, the user can remove the consumable cartridge 1 from the printing device to complete the disassembly of the consumable cartridge 1. During the whole process, the guiding rib 1003 does not contact the first groove 140 and the space part 151. The technical solution provided by this embodiment can effectively solve the problem that when the user installs the consumable cartridge into the printing device, in the prior art, for example, when the user installs the consumable cartridge into the printing device in a non-standard installation manner, during the process of the guiding protrusion 1142 entering the inlet part 121, due to the deviation of the entering angle, the sheet-like long-strip-shaped guiding protrusion 1142 causes blockage with the two opposite protrusions 1211 at the inlet part 121, resulting in the consumable cartridge not being correctly installed into the installation part 1100 of the printing device, and even causing damage to the guiding protrusion 1142. At the same time, by providing a second guiding protrusion 123 at a position adjacent to the locking part 124 in the locking path 122, the movement path of the guiding protrusion 1142 in the locking path 122 can be limited, and the attitude of the consumable cartridge during the installation process can be corrected, so that the guiding protrusion 1142 can move along the correct installation path to contact the second inclined surface 1271, and enter the corresponding engaging part 127 through the guidance of the second inclined surface 1271, improving the operability and accuracy of the consumable cartridge installation process.

[0140] In addition, by limiting the size and structure of the inner enclosure wall 150 and the first groove 140, the guide rib 1003 is prevented from contacting the inner enclosure wall 150 (including the space portion 151) and the first groove 140 when the consumable box is installed in the installation portion 1100 or removed from the installation portion 1100, thereby avoiding the problem in the prior art that the user fails to accurately align the guide rib 1003 with the guide track of the consumable box when installing the consumable box into the printing device, resulting in installation interference, jamming, and even damage to the guide rib 1003 during the installation of the consumable box. The solution of the present application can greatly improve the safety, operability, adaptability, and user experience of the installation of the consumable box and the printing device.

[0141] In this embodiment, the remaining structural design and the process of loading or removing the consumable box from the printing device are the same as those in the first embodiment and will not be described in detail.

[0142] Embodiment six:

[0143] As shown in Figure 16 and Figure 17 As shown, different from the fifth embodiment, in this embodiment, a bypass portion 129 is provided on the side of the guided portion 120 facing the first groove 140, and the bypass portion 129 is located between the second guide protrusion 123 and the clamping portion 127. For example, when the user is installing the consumable box into the printing device, due to the skewed installation posture of the ink cartridge and other reasons, the swing angle of the guide portion 1140 around the movable axis 1141 is too large, resulting in the guide protrusion 1142 not entering from the partition portion 110 into the entrance portion 121 of the guided portion 120, but moving to the first groove 140 between the first area 100 and the second area 200. At this time, the guide protrusion 1142 can also re-enter the locking path 122 through the bypass portion 129, contact the second inclined surface 1271, and be guided by the second inclined surface 1271 to enter the clamping portion 127 adjacent to the second area 200. A guide surface 1291 is provided on the side entry portion 129, so that the guide protrusion 1142 can fall into the locking path 122 more easily along the guide surface 1291 under the action of external force. The technical solution provided by this embodiment can effectively solve the problem that when the consumable box is installed in the printing device, the installation posture of the consumable box is offset due to the user's non-standard installation, so that the guide protrusion 1142 mistakenly enters the first groove 140, causing interference with the installation of the consumable box or causing damage to the guide protrusion 1142.

[0144] In this embodiment, the remaining structural design and the process of loading or removing the consumable box from the printing device are the same as those in the fifth embodiment and will not be described in detail.

[0145] It should be noted that, if the consumable box 1 is installed in a standard manner, the present embodiment can also adopt the method of installing the consumable box in the printing device in the fifth embodiment.

[0146] Embodiment seven:

[0147] As shown Figure 18 in the figure, different from Embodiment 5, at least one protrusion 61 is provided on an upper portion of a side wall 60 adjacent to the bottom wall 10 and / or the top wall 70. That is, at least one protrusion 61 can be provided on an upper portion of a side wall 60 adjacent to the bottom wall 10, or at least one protrusion 61 can be provided adjacent to the top wall 70, or at least one protrusion 61 can be provided adjacent to both the bottom wall 10 and the top wall 70; alternatively, at least one protrusion 61 is provided on one or more side walls 60; alternatively, at least one protrusion 61 is provided on two side walls 60 adjacent to the bottom wall 10 and / or the top wall 70. That is, on the two side walls 60, at least one protrusion 61 can be provided adjacent to the bottom wall 10, or at least one protrusion 61 can be provided adjacent to the top wall 70, or at least one protrusion 61 can be provided adjacent to both the bottom wall 10 and the top wall 70.

[0148] In some examples, when the consumable cartridge is being loaded into the installation portion 1100, the two protrusions 61 provided on the two side walls 60 adjacent to the bottom wall 10 are respectively in contact with the side wall of the frame 1002 and the guiding rib 1003 provided in the adjacent installation portion 1100, facilitating the user to install the consumable cartridge in a non-standard manner and realizing the correction of the installation posture of the consumable cartridge.

[0149] In addition, when the consumable cartridge is being loaded into the installation portion 1100, by using the two protrusions 61 to be respectively in contact with the side wall of the frame 1002 and the guiding rib 1003 provided in the adjacent installation portion 1100, it is avoided that the consumable cartridge is accidentally affected by a force in the third direction during the installation process, resulting in shaking, and further hitting the guiding rib 1003, which may cause the risk of damage to the guiding rib.
