DETAILED DESCRIPTION OF THE INVENTION

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present application.

[0028] It should be noted that the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In the present application, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, or an internal communication between two elements or an 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 application can be understood according to specific situations.

[0030] In the present application, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "over" and "on" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. A first feature being "below", "under" and "beneath" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0031] In the above description, the description with reference to the terms "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" etc. means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the described specific features, structures, materials, or characteristics can be combined in any one or more embodiments or examples in an appropriate manner. In addition, those skilled in the art can combine and integrate different embodiments or examples and the features of different embodiments or examples described in this specification without conflicting with each other.

[0032] In related technologies, there are problems such as interference, jamming, and failure to install the consumable cartridge in place during installation, and even damage to the guide rib, resulting in a poor user experience. The applicant found that the cause of this problem is that the user's operation is non-standard when installing the consumable cartridge into the printing device, that is, failing to accurately align the inner surrounding wall 150a of the consumable cartridge with the guide rib 1003 provided on the frame 1120 of the installation unit 1000, which may lead to a deviation or change in the installation position or posture of the consumable cartridge, causing problems such as interference, jamming, and failure to install the consumable cartridge in place, and even damage to the guide rib, resulting in a poor user experience.

[0033] To solve the above problems, the embodiment of the present application provides a consumable cartridge. The guided part can be closer to the front wall than the inner surrounding wall in the length direction of the consumable cartridge, so that when installing the consumable cartridge, there is no need to align the guide rib in the printing device with the inner surrounding wall, which can effectively avoid the problems of interference, jamming, and failure to install the consumable cartridge in place, and even damage to the guide rib.

[0034] Alternatively, the inner surrounding wall can be completely cut off, so that when installing the consumable cartridge, there is no need to accurately align the guide rib in the printing device with the inner surrounding wall of the spacing part, which can effectively avoid the problems of interference, jamming, and failure to install the consumable cartridge in place, and even damage to the guide rib.

[0035] The consumable cartridge provided by the embodiment of the present application will be described in detail below in conjunction with specific embodiments.

[0036] As shown in Figs. 2 and 3, a consumable cartridge provided by the present application is detachably installed in the installation unit 1000 of the printing device. The consumable cartridge stores ink. 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, which ejects the ink onto the printing medium to form text or patterns. The installation unit 1000 can reciprocate along the guide rail to realize printing. As shown in Fig. 3, the installation unit 1000 includes a main body 1001 and a frame 1002, and the frame 1002 is installed on the main body 1001. The installation unit 1000 includes a plurality of installation parts 1100, and the consumable cartridges containing different inks are respectively installed into the corresponding installation parts 1100. The frame 1002 is provided with guide ribs 1003 at intervals, and the adjacent installation parts 1100 are separated by the guide ribs 1003.

[0037] An interface unit 1120 is provided on the rear wall surface 1101 of each installation part 1100, and 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 member 1123, and the deformation member 1123 is arranged around the inflation part 1122. The installation part 1100 also includes a guide part 1140. The guide part 1140 and the movable shaft 1141 are arranged on the bottom wall surface 1102 and can swing at a certain angle around the movable shaft 1141. One end of the guide part 1140 far from the movable shaft 1141 is provided with a guide protrusion 1142, and the guide protrusion 1142 is configured as a sheet-like long strip structure. The bottom wall surface 1102 of each installation part 1100 is also provided with a first adaptation part 1150, and the frame 1002 is also provided with a second adaptation part 1160. Among them, one of the multiple installation parts 1100 is used to accommodate the consumable cartridge of black ink, and a third adaptation part 1170 is also provided at a position adjacent to the first adaptation part 1150 in this installation part 1100.

[0038] A pin assembly 1130 is also 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 of the pin assembly 1130 is higher than that of the interface unit 1120. The pin assembly 1130 includes a plurality of pins 1131, and a guide slope 1132 is provided on the pin assembly 1130 at a position adjacent to the pins 1131.

[0039] To better describe the consumable cartridge, a coordinate system is established as shown in Fig. 4: 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, where 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 angles between the first direction, the second direction, and the third direction can be 90°. In other possible implementations, the angle between the first direction and the second direction can be 80° to 100°, such as 80°, 85°, 90°, 95°, or 100°.

[0040] As shown in Figs. 4 and 5, the consumable cartridge 1 includes a main body, which is formed by enclosing a plurality of walls. The main body stores ink. 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 opposite side walls 60. A fluid interface part 30 (see Fig. 1) is provided on the front wall 20, and the fluid interface part 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 into the corresponding installation part 1100, the ink outlet 32 is engaged with the ink supply part 1121, the inflation hole 31 is engaged with the inflation part 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 also includes a cartridge installation part 80, which is arranged on a notch part 21 provided on the main body of the consumable cartridge. In the second direction, the notch part 21 is configured to form a depression from the front wall 20 toward the direction away from the front wall 20. An electrical interface component 40 is arranged on the cartridge installation part 80, and the cartridge installation part 80 can be fixed or detachably arranged at the notch part 21. A guided slope 1311 is provided at the edge of the cartridge installation part 80. When the consumable cartridge 1 is installed into the printing device, the guided slope 1311 provided on the cartridge installation part 80 is guided by the guide slope 1132 in the pin assembly 1130, so that the electrical interface component 40 is electrically connected to the pins 1131 of the pin assembly 1130.Embodiment 1:

[0041] As shown in Fig. 6, the bottom wall 10 of the consumable cartridge 1 is configured to include a first area 100. The first area 100 is provided with a spaced part 110, a guided part 120, and a non-spaced part 130. In the second direction, the non-spaced part 130, the guided part 120, and the spaced part 110 are arranged in sequence, with the guided part 120 located between the non-spaced part 130 and the spaced part 110. Compared with the guided part 120, the non-spaced part 130 is located in the first area 100 at a position farther from the ink outlet 32, and the spaced part 110 is located in the first area 100 at a position closer to the ink outlet 32.

[0042] The bottom wall 10 also includes a second area 200. In the third direction, the first area 100 and the second area 200 are adjacently arranged, and in the second direction, the lengths of the first area 100 and the second area 200 are consistent. The bottom wall 10 is also provided with a peripheral surrounding wall 160. In the first direction, the peripheral surrounding wall 160 protrudes from the bottom wall 10, and the peripheral surrounding wall 160 is configured to partially surround the outer sides of the first area 100 and the second area 200. In the first direction, the second area 200 is higher than the non-spaced part 130.

[0043] It should be noted that in the third direction, the projection of the spaced part 110 and the part of the second area 200 close to the front wall 20 at least partially overlaps, that is, in the first direction, the height of at least part of the surface of the spaced part 110 is slightly higher than or equal to the height of the surface of the part of the second area 200 close to the front wall 20. This effectively avoids the problem in the prior art where the surface of the part of the second area 200 close to the front wall 20 of the consumable cartridge is higher than the spaced part 110 in the first area 100, thereby effectively preventing the installation position deviation caused by the second area 200 of the bottom wall of the consumable cartridge being higher than the first area 100 during the installation of the consumable cartridge into the printing device, which may further lead to interference, jamming, and failure to install the consumable cartridge in place.

[0044] 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 area 200 refers to the height of the second area 200 relative to the top wall 70 in the first direction.

[0045] There is a first groove 140 between the first area 100 and the second area 200. Specifically, the first area 100 is not connected to the second area 200, and the first area 100 and the second area 200 are separated by the first groove 140.

[0046] In the third direction, the first groove 140 is at least partially connected to the guided part 120.

[0047] The inner surrounding wall 150 may be formed in the second area 200. Specifically, the inner surrounding wall 150 may be formed on a part of the side wall of the second area 200 facing the first area 100. The inner surrounding wall 150 is configured to have a concave-convex part 210. The concave-convex part 210 includes convex parts facing the first area 100 and concave parts facing the second area 200, and the convex parts and concave parts are alternately arranged in the second direction. In other embodiments, the inner surrounding wall 150 may also be formed on a part of the side wall of the first area (100) facing the second area (200). Alternatively, the inner surrounding wall 150 may also be formed on a part of the side wall of the first area (100) facing the second area (200) and on a part of the side wall of the second area 200 facing the first area 100.

[0048] In the third direction, the inner surrounding wall 150 and the guided part 120 are arranged at intervals.

[0049] In the second direction, there is a distance between the inner surrounding wall 150 and the front wall 20, and the inner surrounding wall 150 is configured to extend toward the rear wall 50.

[0050] There is an opening 141 connected to the first groove 140 between the first area 100 and the second area 200, and the opening 141 is closer to the front wall 20 than the first groove 140 in the second direction. The opening 141 can provide a distance between the inner surrounding wall 150 and the front wall 20.

[0051] The shape of the opening 141 is preferably a horn shape. The end of the opening 141 far from the first groove 140 is a first end, which is connected to the front wall 20; the end of the opening 141 close to the first groove 140 is a second end, which is connected to the first groove 140. The width of the opening 141 gradually decreases from the first end to the second end. This arrangement can make the width of the opening 141 larger than that of the first groove 140. During the installation of the consumable cartridge into the printing device, since the width of the opening 141 is larger than that of the first groove 140, there is no need to align the guide rib 1003 in the printing device with the first groove 140, and the guide rib 1003 will not interfere with the consumable cartridge, thereby improving the convenience, operability, adaptability of installing the consumable cartridge with the printing device, and the user experience.

[0052] It should be noted that the shape of the opening 141 can also be other shapes such as a quadrilateral or a sector, so as to achieve the purpose that during the installation of the consumable cartridge into the installation unit, there is no need to align the guide rib 1003 in the printing device with the first groove 140, so that the guide rib 1003 will not interfere with the consumable cartridge.

[0053] As shown in Fig. 7, the side wall of the first area 100 facing the opening 141 is a first flange wall 1411, which is located on a part of the side wall of the first area 100 facing the second area 200, and the first flange wall 1411 is connected to the front wall 20. During the installation of the consumable cartridge into the printing device, the first flange wall 1411 can avoid the guide rib 1003, preventing the guide rib 1003 from interfering with the consumable cartridge.

[0054] The shape of the first flange wall 1411 is arc-shaped.

[0055] As shown in Figs. 6, 7, and 8, the guided part 120 at least includes an inlet part 121, a locking path 122, an intersection path 125, and an unlocking path 126, and the intersection path 125 is connected to the locking path 122 and the unlocking path 126 respectively.

[0056] The guided part 120 further includes guide protrusions. The guide protrusions are used to limit the path of the guide protrusion 1142. The guide protrusions may be located at positions in the guided part 120 facing the locking path 122 and the inlet part 121. In other embodiments, the guide protrusions may also be located at positions in the guided part 120 facing the locking path 122. Alternatively, the guide protrusions may also be located at positions in the guided part 120 facing the inlet part 121.

[0057] The guide protrusions include a first guide protrusion 1213 and a second guide protrusion 123.

[0058] In the third direction, one end of the inlet part 121 is provided with a bump 1211, and the other end of the inlet part 121 is provided with a first guide protrusion 1213. A first notch 1212 is formed between the bump 1211 and the first guide protrusion 1213, and the first notch 1212 facilitates the entry of the guide protrusion 1142 into the locking path 122. In the third direction, the locking path 122 and the unlocking path 126 are arranged opposite to each other. In the direction opposite to the second direction, both the locking path 122 and the unlocking path 126 are configured to have one end starting from the inlet part 121 and the other end extending toward the intersection path 125.

[0059] The first guide protrusion 1213 includes a first guide surface 121a and a second guide surface 121b, where the first guide surface 121a intersects with the second guide surface 121b. The first guide surface 121a is inclined toward the second area 200 along the second direction, and the second guide surface 121b is inclined toward the locking path 122 along the second direction.

[0060] The second guide protrusion 123 is spaced apart from the first guide protrusion 1213. The first guide protrusion 1213 is closer to the front wall 20 than the second guide protrusion 123 in the second direction.

[0061] The second guide protrusion 123 includes a guide convex end 123a and a third guide surface 123b, where the guide convex end 123a faces the second area 200, and the third guide surface 123b is inclined toward the locking path 122 along the second direction.

[0062] In the third direction, the guide convex end 123a is closer to the second area 200 than the third guide surface 123b.

[0063] A locking part 124 is further provided in the locking path 122. The locking part 124 is located between the locking path 122 and the unlocking path 126, and includes a first surface 1241, a locking surface 1242, and a second surface 1243, which together form the locking part 124. Among them, the surface of the locking part 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.

[0064] The intersection path 125 is further provided with clamping parts 127. In this embodiment, there are two clamping parts 127, which are spaced apart on the side of the guided part 120 close to the non-spaced part 130. In the direction opposite to the second direction, the clamping parts 127 are farther from the inlet part 121 than the locking part 124.

[0065] The guided part 120 includes a boss 128, which is located between the two clamping parts 127. In this embodiment, the clamping parts 127 are configured as slot structures, but they can also be configured as other structures to match the structures of the guided part 120 and the guide part 1140 in the printing device. The boss 128 has a first inclined surface 1281, which is inclined toward one of the clamping parts 127. A second inclined surface 1271 is further provided on the outer side of the clamping part 127 close to the second area 200. In this embodiment, a second guide protrusion 123 is provided in the locking path 122 adjacent to the locking part 124 to limit the movement path of the guide protrusion 1142 in the locking path 122 and correct the posture of the consumable cartridge during installation, so that the guide protrusion 1142 can move along the correct installation path to contact the second inclined surface 1271 and be guided into the corresponding clamping part 127 through the second inclined surface 1271, improving the operability and accuracy of the consumable cartridge installation process.

[0066] The guided part 120 includes a locking path 122 and an unlocking path 126 located on both sides of the locking part 124, and an intersection path 125 located on the front side of the locking part 124. In the third direction, the locking path 122 is on the side close to the second area 200, the unlocking path 126 is on the side far from the second area 200, and the intersection path 125 connects the locking path 122 and the unlocking path 126.

[0067] The standard installation process of the consumable cartridge 1 into the printing device is as follows: an external force in the direction opposite to the second direction is applied to the consumable cartridge 1, and it enters the installation part 1100 along the second direction. The guide protrusion 1142 in the guide part 1140 passes through the spaced part 110 and reaches the first position of the installation part 1100, where it arrives at the inlet part 121 of the guided part 120 and enters the guided part 120 through the first notch 1212 of the inlet part 121. It should be noted that during the entire process, the guide protrusion 1142 does not contact the spaced part 110, and the guide rib 1003 enters the first groove 140 from the opening 141 without contacting the first groove 140 or the opening 141. After the guide protrusion 1142 enters the guided part 120 through the first notch 1212 of the inlet part 121, the guide part 1140 swings at a certain angle around the movable shaft 1141, allowing the guide protrusion 1142 to enter the locking path 122. The guide protrusion 1142 moves along the locking path 122 to between the second guide protrusion 123 and the locking part 124. The second guide protrusion 123 drives the guide protrusion 1142 to shift toward the locking part 124 and move along the first surface 1241 of the locking part 124. When the guide protrusion 1142 moves away from the first surface 1241 and enters the intersection 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 guide inclined surface 1132 in the pin assembly 1130, and the guide inclined surface 1132 continues to guide the consumable cartridge to move toward the third position of the installation part 1100. As the consumable cartridge continues to move toward the third position, the electrical interface component 40 is electrically connected to the pins 1131 of the 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 pre-engaged with the ink supply part 1121 and the inflation part 1122 in the installation part 1100, respectively, and the deformation member 1123 arranged around the inflation part 1122 contacts the front wall 20 of the consumable cartridge and starts to deform.

[0068] As the consumable cartridge continues to move from the third position toward the target installation position, the guide protrusion 1142 moves to contact the second inclined surface 1271 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. At this point, the deformation member 1123 arranged around the ink supply part 1121 reaches its maximum deformation. Subsequently, the external force acting on the consumable cartridge 1 is released, and the consumable cartridge 1 moves in the second direction under the restoring force of the deformation member 1123. The guide protrusion 1142 disengages from the clamping part 127, falls onto the locking surface 1242, slides along the inclined surface on the locking surface 1242, and finally settles into the depression 1244, thereby completing the installation of the consumable cartridge 1. Throughout the process, the guide rib 1003 does not contact the first groove 140 or the space part 151. When the consumable cartridge 1 is fully installed into the installation part 1100, the guide rib 1003 is located in the first groove 140, a part of the peripheral surrounding wall 160 is supported on the second adaptation part 1160 and the third adaptation part 1170. In the first direction, the spaced part 110 is located above the first adaptation part 1150 without contact, the non-spaced part 130 and a part of the second area 200 are located above the second adaptation part 1160 without contact, and the spaced part 110 and another part of the second area 200 are located above the third adaptation part 1170 without contact.

[0069] Case 1 of non-standard installation of the consumable cartridge 1 into the printing device: An external force in the direction opposite to the second direction is applied to the consumable cartridge 1, and it enters the installation part 1100 along the second direction. The guide protrusion 1142 in the guide part 1140 deviates from the inlet part 121 of the guided part 120, i.e., it does not enter the guided part 120 through the first notch 1212 of the inlet part 121. Instead, the guide protrusion 1142 moves along the first guide surface 121a of the first guide protrusion 1213 to the second guide surface 121b, and re-enters the locking path 122 along the second guide surface 121b. The guide protrusion 1142 moves along the locking path 122 to between the second guide protrusion 123 and the locking part 124. The second guide protrusion 123 drives the guide protrusion 1142 to shift toward the locking part 124 and move along the first surface 1241 of the locking part 124. The remaining installation process of the consumable cartridge 1 is the same as the standard installation process, which will not be elaborated here.

[0070] Case 2 of non-standard installation of the consumable cartridge 1 into the printing device: An external force in the direction opposite to the second direction is applied to the consumable cartridge 1, and it enters the installation part 1100 along the second direction. The guide protrusion 1142 in the guide part 1140 deviates from the inlet part 121 of the guided part 120, i.e., it does not enter the guided part 120 through the first notch 1212 of the inlet part 121. Instead, the guide protrusion 1142 moves along the first guide surface 121a of the first guide protrusion 1213 to the guide convex end 123a of the second guide protrusion 123. As the consumable cartridge continues to move, the guide protrusion 1142 moves from the guide convex end 123a to the third guide surface 123b, and re-enters the locking path 122 along the third guide surface 123b. The guide protrusion 1142 moves to contact the second inclined surface 1271 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, which will not be elaborated here.

[0071] As the consumable cartridge 1 is used and the ink stored in it is exhausted, the user needs to remove the consumable cartridge 1 from the installation part 1100. Specifically: A force in the second direction is applied to the consumable cartridge 1. The guide protrusion 1142 in the guide part 1140 slides from the depression 1244 along the other inclined surface of the locking surface 1242, disengages from the locking surface 1242, and enters the intersection path 125. As the consumable cartridge 1 continues to move, the guide protrusion 1142 contacts the boss 128 in the intersection path 125, displaces along the first inclined surface 1281 of the boss 128, and enters another clamping part 127 far from the second area 200. At this point, the deformation member 1123 arranged around the ink supply part 1121 contacts the front wall of the consumable cartridge 1 and is compressed. The external force is then released, and the consumable cartridge moves in the opposite direction of the second direction under the restoring force of the deformation member 1123, causing the guide protrusion 1142 to disengage from the other clamping part 127, enter the unlocking path 126, contact the second surface 1243 of the locking part 124, move 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 pin 1131, the guide rib 1003 disengages from the space part 151, and the user can then remove the consumable cartridge 1 from the printing device, completing the disassembly. Throughout the process, the guide rib 1003 does not contact the first groove 140 or the opening 141.

[0072] Meanwhile, by providing the second guide protrusion 123 in the locking path 122 adjacent to the locking part 124, the movement path of the guide protrusion 1142 in the locking path 122 can be limited, and the posture of the consumable cartridge can be corrected during installation, ensuring that the guide protrusion 1142 can move along the correct installation path to contact the second inclined surface 1271 and be guided into the corresponding clamping part 127 through the second inclined surface 1271, thus improving the operability and accuracy of the consumable cartridge installation process.Embodiment 2:

[0073] As shown in Fig. 9, the difference between Embodiment 2 and Embodiment 1 is that the length of the consumable cartridge 1 is shorter than that in Embodiment 1, and there is no first groove or opening between the first area 100 and the second area 200. In addition, in the first area 100, along the second direction, the non-spaced part 130 is higher than the second area 200, and the second area 200 has no peripheral surrounding wall 160.

[0074] The inner surrounding wall 150 is formed in the first area 100. Specifically, the inner surrounding wall 150 is formed on a part of the side wall of the first area 100 facing the second area 200.

[0075] In the first direction, the height of the inner surrounding wall 150 may be greater than the height of the second area 200. In other embodiments, in the first direction, the height of the inner surrounding wall 150 may be greater than the height of the first area 100.

[0076] In the second direction, the inner surrounding wall 150 is at least partially connected to the guided part 120.

[0077] In the third direction, the second area 200 is at least partially connected to the guided part 120.

[0078] In this embodiment, the remaining structural design methods and the process of installing the consumable cartridge into the printing device or disassembling it from the printing device are the same as those in Embodiment 1, and will not be repeated here.Embodiment 3:

[0079] As shown in Fig. 10, the difference between Embodiment 3 and Embodiment 2 is that the length of the consumable cartridge 1 is longer than that in Embodiment 2, the first area 100 is connected to the second area 200, and the first area 100 is provided with a second groove 170. The second groove 170 is configured to be recessed toward 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 position in the installation unit 1000 when the consumable cartridge 1 is installed into the installation unit of the printing device.

[0080] 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.

[0081] The difference between the guided part 120 in Embodiment 3 and that in Embodiment 1 or 2 is that in addition to the inlet part 121, the locking path 122, the intersection path 125, and the unlocking path 126, the guided part 120 in this embodiment has bumps 1211 at both ends of the inlet part 121 in the third direction, and a first notch 1212 is formed between the two bumps 1211. The guided part 120 in Embodiment 3 does not have the first guide protrusion 1213 or the second guide protrusion 123.

[0082] In this embodiment, the remaining structural design methods and the process of installing the consumable cartridge into the printing device or disassembling it from the printing device are the same as those in Embodiment 2, and will not be repeated here.Embodiment 4:

[0083] As shown in Fig. 11, the difference between Embodiment 4 and Embodiment 3 is that there is no second area 200, and the peripheral surrounding wall 160 is provided on at least three side walls of the first area 100. The second groove 170 has a second flange wall 170a in the width direction of the consumable cartridge.

[0084] In this embodiment, the remaining structural design methods and the process of installing the consumable cartridge into the printing device or disassembling it from the printing device are the same as those in Embodiment 3, and will not be repeated here.Embodiment 5

[0085] As shown in Fig. 12, the difference between Embodiment 5 and Embodiment 1 lies in that the bottom wall 10 includes at least one inner surrounding wall 150, and the inner surrounding wall 150 is configured to protrude from the bottom wall 10. In this embodiment, at least one inner surrounding wall 150 is arranged between the first area 100 and the second area 200.

[0086] In some examples, the number of inner surrounding walls 150 is preferably two. The two inner surrounding walls 150 are arranged at intervals and adjacent to each other, and are respectively disposed on the outer side of at least a part of the non-spaced part 130 in the first area 100 and at least a part of the second area 200 close to the rear wall 50. That is, in the direction opposite to the second direction, each of the two inner surrounding walls 150 is located on the rear side of the guided part 120. In other words, the guided part 120 is closer to the front wall 20 than the inner surrounding wall 150 in the second direction.

[0087] A first groove 140 is provided between the first area 100 and the second area 200. The two inner surrounding walls 150 and a part of the partial peripheral surrounding wall 160 together form a semi-enclosed space part 151. A part of the first groove 140 extends into the space part 151, and another part of the first groove 140 is located outside the space part 151. It can be understood that the inner surrounding wall 150 is formed on at least a part of the first groove 140. The first groove 140 is configured to extend from a position on the bottom wall 10 adjacent to the front wall 20 to a position close to the rear wall 50. In the second direction, the side of the first groove 140 close to the front wall 20 is provided with an opening 141 connected to the first groove 140. When the consumable cartridge 1 is installed into the installation part of the printing device, the guide rib 1003 in the printing device enters the first groove 140 from the opening 141. After the consumable cartridge 1 moves past the third position in the installation part 1100 of the printing device, that is, after the fluid interface part 30 in the consumable cartridge 1 is engaged with the interface unit 1120 in the installation part 1100, the guide rib 1003 enters the space part 151. When the consumable cartridge is installed into or disassembled from the installation part 1100, the guide rib 1003 does not contact the first groove 140 or the inner surrounding wall 150. When the consumable cartridge 1 is completely installed into the installation part 1100, the guide rib 1003 is located in the space part 151.

[0088] In the first direction, the inner surrounding wall 150 is higher than the first area 100, higher than the second area 200, and higher than the first groove 140.

[0089] It should be noted that each of the two inner surrounding walls 150 is configured such that one end is connected to the peripheral surrounding wall 160 which is arranged around the bottom wall 10 and connected to the rear wall 50, and the other end is far from the rear wall 50. In the direction opposite to the second direction, the distance between the end of each of the two inner surrounding walls 150 far from the rear wall 50 and the rear wall 50 is D1, and the range of D1 is 0 ≤ D1 ≤ 33mm.

[0090] As shown in Fig. 13, one side of the inlet part 121 of the guided part 120 is provided with a bump 1211, and the other side is provided with a second notch 1214. In the third direction, the second notch 1214 faces the bump 1211, and the second notch 1214 is close to the second area 200. The second notch 1214 facilitates the entry of the guide protrusion 1142 into the locking path 122.

[0091] As shown in Figs. 14A-14E, the process of installing the consumable cartridge 1 into the printing device is as follows: an external force in the direction opposite to the second direction is applied to the consumable cartridge 1, and it enters the installation part 1100 along the second direction. When the guide protrusion 1142 in the guide part 1140 passes through the spaced part 110 and reaches the first position of the installation part, the guide protrusion 1142 arrives at the inlet part 121 of the guided part 120 and enters the guided part 120 from the inlet part 121. It should be noted that during the entire process, the guide protrusion 1142 does not contact the spaced part 110, and the guide rib 1003 enters the first groove 140 from the opening 141 without contacting the first groove 140. After the guide protrusion 1142 enters the guided part 120 from the notch 1212 at the inlet part 121, the guide part 1140 swings at a certain angle around the movable shaft 1141, allowing the guide protrusion 1142 to enter the locking path 122. The guide protrusion 1142 moves along the locking path 122 to between the second guide protrusion 123 and the locking part 124. The second guide protrusion 123 drives the guide protrusion 1142 to shift toward the locking part 124 and move along the first surface 1241 of the locking part 124. When the guide protrusion 1142 moves away from the first surface 1241 and enters the intersection 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 guide inclined surface 1132 in the pin assembly 1130, and the guide inclined surface 1132 continues to guide the consumable cartridge to move toward the third position of the installation part 1100. As the consumable cartridge continues to move toward the third position, the electrical interface component 40 is electrically connected to the pins 1131 of the 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 pre-engaged with the ink supply part 1121 and the inflation part 1122 in the installation part 1100, respectively, and the deformation member 1123 arranged around the ink supply part 1121 contacts the front wall 20 of the consumable cartridge and starts to deform. After the consumable cartridge passes the third position of the installation part 1100, the guide rib 1003 enters the space part 150, but the guide rib 1003 does not contact the space part 151.

[0092] As the consumable cartridge continues to move from the third position toward the target installation position, the guide protrusion 1142 moves to contact the second inclined surface 1271 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. At this point, the deformation member 1123 arranged around the ink supply part 1121 reaches its maximum deformation. Subsequently, the external force acting on the consumable cartridge 1 is released, and the consumable cartridge 1 moves in the second direction under the restoring force of the deformation member 1123. The guide protrusion 1142 disengages from the clamping part 127, falls onto the locking surface 1242, slides along the inclined surface on the locking surface 1242, and finally settles into the depression 1244, thereby completing the installation of the consumable cartridge 1. Throughout the process, the guide rib 1003 does not contact the first groove 140 or the space part 151. When the consumable cartridge 1 is fully installed into the installation part 1100, the guide rib 1003 is located in the first groove 140, a part of the peripheral surrounding wall 160 is supported on the second adaptation part 1160 and the third adaptation part 1170. In the first direction, the spaced part 110 is located above the first adaptation part 1150 without contact, the non-spaced part 130 and a part of the second area 200 are located above the second adaptation part 1160 without contact, and the spaced part 110 and another part of the second area 200 are located above the third adaptation part 1170 without contact.

[0093] As shown in Figs. 15A-15C, as the consumable cartridge 1 is used and the ink stored in it is exhausted, the user needs to remove the consumable cartridge 1 from the installation part 1100. Specifically: A force in the second direction is applied to the consumable cartridge 1. The guide protrusion 1142 in the guide part 1140 slides from the depression 1244 along the other inclined surface of the locking surface 1242, disengages from the locking surface 1242, and enters the intersection path 125. As the consumable cartridge 1 continues to move, the guide protrusion 1142 contacts the boss 128 in the intersection path 125, displaces along the first inclined surface 1281 of the boss 128, and enters another clamping part 127 far from the second area 200. At this point, the deformation member 1123 arranged around the ink supply part 1121 contacts the front wall of the consumable cartridge 1 and is compressed. The external force is then released, and the consumable cartridge moves in the opposite direction of the second direction under the restoring force of the deformation member 1123, causing the guide protrusion 1142 to disengage from the other clamping part 127, enter the unlocking path 126, contact the second surface 1243 of the locking part 124, move 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 pin 1131, the guide rib 1003 disengages from the space part 151, and the user can then remove the consumable cartridge 1 from the printing device, completing the disassembly. Throughout the process, the guide rib 1003 does not contact the first groove 140 or the space part 151. The technical solution provided in this embodiment can effectively solve the problem that in the prior art, when the user installs the consumable cartridge into the printing device in a non-standard way, the guide protrusion 1142 is blocked by the two oppositely arranged bumps 1211 at the inlet part 121 due to the deviation of the entry angle when entering the inlet part 121, resulting in the consumable cartridge being unable to be correctly installed into the installation part 1100 of the printing device, and even the guide protrusion 1142 being damaged. Meanwhile, by arranging the second guide protrusion 123 at a position adjacent to the locking part 124 in the locking path 122, the movement path of the guide protrusion 1142 in the locking path 122 can be limited, and the posture of the consumable cartridge can be corrected during installation, so that the guide protrusion 1142 can move along the correct installation path to contact the second inclined surface 1271 and be guided into the corresponding clamping part 127 through the second inclined surface 1271, improving the operability and accuracy of the consumable cartridge installation process.

[0094] In addition, by defining the sizes and structures of the inner surrounding wall 150 and the first groove 140, it is ensured that during the process of installing the consumable cartridge into the printing device or disassembling it from the installation part 1100, the guide rib 1003 is prevented from contacting the inner surrounding wall 150 (including the space part 151) and the first groove 140. This avoids the problems in the prior art, such as installation interference, jamming, and even damage to the guide rib 1003 during the installation of the consumable cartridge, which are caused by the user's failure to accurately align the guide rib 1003 with the guide track of the consumable cartridge when installing the consumable cartridge into the printing device. The solution of the present application can significantly improve the safety, operability, adaptability of installing the consumable cartridge with the printing device, and the user experience.

[0095] In this embodiment, the remaining structural design methods and the process of installing the consumable cartridge into the printing device or disassembling it from the printing device are the same as those in Embodiment 1, and will not be repeated here.Embodiment 6:

[0096] As shown in Figs. 16 and 17, different from Embodiment 5, in this embodiment, a side entry part 129 is provided on the side of the guided part 120 facing the first groove 140, and the side entry part 129 is located between the second guide protrusion 123 and the clamping part 127. For example, if the user installs the consumable cartridge into the printing device with a skewed posture, the guide part 1140 may swing excessively around the movable shaft 1141, causing the guide protrusion 1142 to fail to enter the inlet part 121 of the guided part 120 from the spaced part 110 and instead move into the first groove 140 between the first area 100 and the second area 200. In this case, the guide protrusion 1142 can re-enter the locking path 122 through the side entry part 129, contact the second inclined surface 1271, and be guided by the second inclined surface 1271 into the clamping part 127 adjacent to the second area 200. The side entry part 129 is provided with a guide surface 1291, which allows the guide protrusion 1142 to more easily slide into the locking path 122 along this guide surface 1291 under external force. The technical solution of this embodiment effectively solves the problem of installation interference or damage to the guide protrusion 1142 caused by the guide protrusion 1142 mistakenly entering the first groove 140 due to non-standard installation postures.

[0097] In this embodiment, the remaining structural designs and the processes of installing the consumable cartridge into the printing device or disassembling it from the printing device are the same as those in Embodiment 5, and will not be repeated.

[0098] It should be noted that if the consumable cartridge 1 is installed in a standard manner, the installation method described in Embodiment 5 is also applicable here.Embodiment 7:

[0099] As shown in Fig. 18, different from Embodiment 5, at least one protruding part 61 is provided on one side wall 60 adjacent to the bottom wall 10 and / or the top wall 70. That is to say, at least one protruding part 61 may be provided on one side wall 60 adjacent to the bottom wall 10, or at least one protruding part 61 may be provided adjacent to the top wall 70, or at least one protruding part 61 may be provided adjacent to both the bottom wall 10 and the top wall 70. Alternatively, at least one protruding part 61 is provided on one or more side walls 60. Alternatively, at least one protruding part 61 is provided on two side walls 60 adjacent to the bottom wall 10 and / or the top wall 70. That is to say, at least one protruding part 61 may be provided on two side walls 60 adjacent to the bottom wall 10, or at least one protruding part 61 may be provided adjacent to the top wall 70, or at least one protruding part 61 may be provided adjacent to both the bottom wall 10 and the top wall 70.

[0100] In some examples, when the consumable cartridge is installed into the installation part 1100, two protruding parts 61 on the two side walls 60 (adjacent to the bottom wall 10) abut against the side wall of the frame 1002 and the guide rib 1003 in the adjacent installation part 1100, respectively. This helps correct the installation posture if the user installs the cartridge irregularly.

[0101] Additionally, during the process of installing the consumable cartridge into the installation part 1100, the two protruding parts 61 are used to abut against the side wall of the frame 1002 and the guide rib 1003 provided in the adjacent installation part 1100 respectively. This prevents the consumable cartridge from shaking due to accidental force in the third direction during installation, thereby avoiding impact on the guide rib 1003 and the risk of damage to the guide rib that may result.

[0102] In this embodiment, the remaining structural designs and the processes of installing the consumable cartridge into the printing device or disassembling it from the printing device are the same as those in Embodiment 5, and will not be repeated.Embodiment 8:

[0103] As shown in Fig. 19, different from Embodiment 5, the inner surrounding wall 150 on the outer side of at least a part of the second area 200 is removed, retaining only the inner surrounding wall 150 adjacent to at least a part of the non-spaced part 130 of the first area 100. Meanwhile, the width of the first groove 140 is increased, meaning the width D3 of the first groove 140 in this embodiment is larger than the width D2 of the first groove 140 in Embodiment 5.

[0104] The remaining structures and the processes of installing the consumable cartridge into the printing device or disassembling it from the printing device are the same as those in Embodiment 5, and will not be repeated.Embodiment 9:

[0105] As shown in Fig. 20, different from Embodiment 1, the second area 200 is removed, while the peripheral surrounding wall 160 that originally enclosed the second area is retained. The inner surrounding wall 150 adjacent to at least a part of the non-spaced part 130 of the first area 100 is also retained. The first groove 140 is located between the first area 100 and the peripheral surrounding wall 160. In the third direction, the projection of the spaced part 110 and the first groove 140 at least partially overlaps, meaning the height of the spaced part 110 is equal to or slightly greater than that of the first groove 140.

[0106] The remaining structures and the processes of installing the consumable cartridge into the printing device or disassembling it from the printing device are the same as those in Embodiment 5, and will not be repeated.Embodiment 10:

[0107] As shown in Fig. 21, different from Embodiment 9, at least a part of the second area 200 is retained, that is, the part of the second area 200 opposite to the non-spaced part 130 in the third direction is retained, and the inner surrounding wall 150 disposed on the non-spaced part 130 and at least a part of the second area is also retained. A part of the first groove 140 is located between the space parts 151, and another part is located on the front side of the second area 200, that is, in the second direction, compared with the second area 200, the other part of the first groove 140 is closer to the front wall 20. In the third direction, the projection of the spaced part 110 and the first groove 140 at least overlaps, which means the height of the spaced part 110 is equal to that of the first groove 140, or the height of the spaced part 110 is slightly greater than that of the first groove 140.

[0108] The remaining structures and the processes of installing the consumable cartridge into the printing device and disassembling it from the printing device are the same as those in Embodiment 9, and will not be repeated here.Embodiment 11:

[0109] As shown in Fig. 22, different from Embodiment 5, in this embodiment, the second area 200 and the peripheral surrounding wall 160 that originally enclosed the second area 200 are removed, and the inner surrounding wall 150 adjacent to at least a part of the non-spaced part 130 of the first area 100 is retained. In the second direction, the distance between the end of the inner surrounding wall 150 configured to be far from the rear wall 50 and the rear wall is D4, and the range of D4 is 0 ≤ D4 ≤ 10mm. In the third direction, the first groove 140 is located on one side of the first area 100.

[0110] The remaining structures and the processes of installing the consumable cartridge into the printing device and disassembling the consumable cartridge from the printing device are the same as those in Embodiment 5, and will not be repeated here.Embodiment 12:

[0111] In this embodiment, neither the first area 100 nor the second area 200 of the consumable cartridge is provided with an inner surrounding wall 150, that is, the inner surrounding wall 150 on the bottom wall 10 of the consumable cartridge is removed.
