Description

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 30, 2024, with application number 202420231634.7 and application name “A Consumable Box”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of printing equipment, and in particular to a consumables box. Background Art

[0003] The consumables cartridge is a key, removable component of a printing device. It is typically mounted on the mounting assembly of the printing device. A guide is provided on the bottom wall of the cartridge. This guide, in conjunction with a guide protrusion on the mounting assembly, guides the cartridge accurately into the printing device. As the cartridge is inserted into or removed from the printing device, the printer's stylus contacts scrape against the terminal surfaces of the cartridge's chip. This contact between the stylus contacts and the chip's terminal surfaces enables communication between the cartridge and the printing device.

[0004] However, during the frequent rubbing between the stylus and the chip terminal, any area on the chip terminal surface is subjected to the same force from the stylus, causing severe wear on the chip terminal surface and the top surface of the stylus, resulting in poor contact between the stylus and the chip terminal surface, affecting the normal use of the consumable box, and thus resulting in a poor user experience.

[0067] As described in the background technology, in the related art, reference Figure 1 As shown, consumable cartridge 1 is installed in a mounting portion of a printing device and is removably mounted thereto. The mounting portion can accommodate multiple consumable cartridges 1. The consumable cartridges 1 cooperate with the printing device to form images and text. For example, consumable cartridge 1 may be an ink cartridge. After the mounting portion is loaded with cyan, magenta, yellow, and black ink cartridges, the printing device can print in different colors, achieving color printing.

[0068] The consumables box 1 is detachably mounted on a mounting portion of a printing device. The consumables box 1 comprises a box body 10, which is used to store printing liquid. For example, the printing liquid may be ink.

[0069] The front wall 10a of the consumables box 1 is provided with an ink outlet 170, which is relatively close to the bottom wall 10e. The printing liquid in the box body 10 can be supplied to the printing device through the ink outlet 170 to form images or text on the print medium. The front wall 10a of the consumables box 1 is also provided with an air inlet 160.

[0070] For the sake of convenience, Figure 1 In the subsequent figures, the direction from the front wall 10a to the rear wall 10b of the box body 10 is defined as a first direction K of the box body. The direction from the left wall 10c to the right wall 10d of the box body 10 is defined as a second direction N. The direction from the bottom wall 10e to the top wall 10f of the box body 10 is defined as a third direction H. The first direction K, the second direction N, and the third direction H all have an included angle, which is 80° to 100°. For example, the first direction K and the second direction N can be at an angle of 85°, 90°, 100°, or the like.

[0071] Reference Figure 1 and Figure 2 As shown, the box body 10 includes a recessed portion 110 , which is a region of the box body 10 formed by the front wall 10 a extending along the first direction K and penetrating the right wall 10 d.

[0072] The box body 10 includes a chip assembly 120, and the recessed portion 110 is used to accommodate the chip assembly 120. The chip assembly 120 is mainly used to communicate with the printing device or monitor the remaining amount of printing liquid in the box body 10.

[0073] The chip assembly 120 includes a chip 121 , and terminals 1211 on the chip 121 are used for information communication with a printing device.

[0074] For ease of understanding, the surface of the terminal 1211 is divided into three areas along the first direction K, namely end A, end B, and end C, and the end closest to the front wall 10a of the box body 10 is set as end A.

[0075] Reference Figure 3 and Figure 4 As shown, the mounting portion 2 includes a mounting frame 20 and a mounting body 21. A consumables supply unit 220 is provided on the mounting body 21, and the position of the consumables supply unit 220 corresponds to the ink outlet 170. The ink outlet 170 can be plugged into the consumables supply unit 220. Similarly, the mounting body 21 is also provided with a gas supply unit 230, and the gas inlet 160 can be plugged into the gas supply unit 230.

[0076] In addition to the above components, the mounting body 21 is further provided with a deformable member 250, which is arranged around the gas supply portion 230. The deformation of the deformable member 250 generates elastic force that acts on the consumable box 1 to fix or assist in removing the consumable box 1.

[0077] Continue to refer to Figure 3 and Figure 4 As shown, a guide fitting component 210 is provided at the bottom of the mounting portion main body 21 , and the guide fitting component 210 can guide the consumable box 1 to be accurately and easily installed into the mounting portion 2 .

[0078] The guide assembly 210 includes a guide member 211 and a movable shaft 212. The movable shaft 212 is mounted on the bottom of the mounting body 21 and is rotatably connected to the mounting body 21. The guide member 211 is mounted on the movable shaft 212, and the guide member 211 rotates on the bottom of the mounting body 21 via the movable shaft 212.

[0079] The guide fitting assembly 210 further includes guide baffles 213. The guide baffles 213 are disposed on both sides of the guide member 211, thereby limiting the rotation angle of the guide member 211 so that the guide member 211 can only swing back and forth around the movable shaft 212.

[0080] The upper surface of the guide member 211 is further provided with a guide protrusion 2110. Specifically, the guide protrusion 2110 provides a guide function when the consumable box 1 is installed.

[0081] Reference Figure 4 and Figure 5 As shown, the mounting body 21 includes at least one stylus assembly 260, and the stylus assembly 260 is located at the upper end of the mounting body 21. The number of stylus assemblies 260 can be set according to the number of consumable boxes 1.

[0082] The contact pin assembly 260 includes a contact pin 261 and a contact pin mounting seat 262. The contact pin 261 is mounted on the mounting body 21 via the contact pin mounting seat 262, which is beneficial to the stability and accuracy of the contact pin 261, thereby achieving stable communication between the contact pin 261 and the terminal 1211 on the chip 121.

[0083] Specifically, contact pin 261 includes contact pin tip 2610, which contacts terminal 1211 on chip 121 to achieve information communication. For example, when consumable cartridge 1 is installed in mounting portion 2 of the printing device, contact pin 261 can undergo slight elastic deformation, generating a force between contact pin tip 2610 and terminal 1211 on chip 121. This ensures the stability of the connection between contact pin tip 2610 and terminal 1211, thereby ensuring the integrity of the communication information.

[0084] Reference Figure 6 and Figure 7 As shown, a guide portion 132 is provided on the bottom wall 10e of the box body 10, extending along the first direction K. The guide portion 132 includes a first guide wall 1321 and a second guide wall 1322, both of which extend along the first direction K. The first guide wall 1321 and the second guide wall 1322 form a guide groove 1323. The guide groove 1323 has a guide opening 1324 facing the front side of the box body 10. The guide groove 1323 has a preset track, and the guide protrusion 2110 enters the preset track within the guide groove 1323 from the guide opening 1324, guiding the consumables box 1 to be accurately and easily installed into the mounting portion 2.

[0085] A locking portion 13233 is provided within the guide groove 1323, located between the first guide wall 1321 and the second guide wall 1322 and near the guide opening 1324. A first groove 13231, a second groove 13232, and a boss 13234 are also provided within the guide groove 1323. The first groove 13231, the second groove 13232, and the boss 13234 are located along the extension direction of the locking portion 13233 along the first direction K. The first groove 13231 and the second groove 13232 are separated by the boss 13234. The first groove 13231 and the second groove 13232 are respectively located near the first guide wall 1321 and the second guide wall 1322. The boss 13234 is inclined toward the rear wall 10b of the box body 10 along the second direction N.

[0086] The locking portion 13233 has three working surfaces. The second working surface 13233b of the locking portion 13233, which faces the second guide wall 1322, is inclined toward the second guide wall 1322 along the first direction K. The third working surface 13233c of the locking portion 13233, which faces the boss 13234, is a curved surface with a depression forming a locking groove, into which the guide protrusion is recessed. The first working surface 13233a of the locking portion 13233, which faces the first guide wall 1321, is approximately parallel to the first guide wall 1321.

[0087] Reference Figures 4 to 7 As shown, the contact between the contact pin assembly and the chip terminal is illustrated using the installation process of the consumables cartridge. During installation of the consumables cartridge 1, the guide protrusion 2110 moves in the direction indicated by the arrow. First, a force is applied to the consumables cartridge 1 in the direction opposite to the first direction K, causing the consumables cartridge 1 to enter the mounting portion 2 in the direction opposite to the first direction K. The guide protrusion 2110 at the bottom of the guide member 211 enters the guide groove 1323 through the guide opening 1324. The guide protrusion 2110 swings about the movable axis 212 and begins to slide along the second working surface 13233b of the locking portion 13233, or begins to move within the channel formed by the second working surface 13233b and the second guide wall 1322. At this point, the contact pin 261 elastically deforms, and the contact pin tip 2610 contacts the A end of the terminal 1211 of the chip 121. A force is generated between the contact pin 261 and the terminal 1211 of the chip 121.

[0088] Then, the guide protrusion 2110 leaves the second working surface 13233b. At this time, the contact position between the contact pin tip 2610 and the terminal 1211 changes from end A to end B. Next, the guide protrusion 2110 enters the second groove 13232, and the contact position between the contact pin tip 2610 and the terminal 1211 changes from end B to end C. At this time, the ink outlet 170 is plugged into the consumable supply unit 220, the inflation port 160 is plugged into the gas supply unit 230, the consumable box 1 compresses the deformable part 250, and the deformable part 250 generates an elastic force. During this process, the elastic deformation of the contact pin 261 does not change, and the force generated between the contact pin 261 and the terminal 1211 of the chip 121 does not change.

[0089] Finally, the force applied to the consumables cartridge 1 is removed, and the deformable member 250 resumes its deformation, forcing the consumables cartridge 1 to move in the first direction K. The guide protrusion 2110 engages the third working surface 13233c of the locking portion 13233. At this point, the contact position between the contact pin tip 2610 and the terminal 1211 of the chip 121 moves from end C to end B. The force between the contact pin 261 and the terminal 1211 of the chip 121 remains unchanged.

[0090] Therefore, the contact force exerted by the contact pin 261 on the terminal 1211 of the chip 121 at ends A, B, and C is the same. The reciprocating friction between the contact pin 261 and the surface of the terminal 1211 of the chip 121 causes severe wear on the contact pin 261 and the surface of the terminal 1211 of the chip 121, resulting in poor contact between the contact pin 261 and the surface of the terminal 121 of the chip 121, affecting the normal use of the consumable cartridge 1 and providing a poor user experience.

[0091] In view of this, an embodiment of the present application provides a consumable box 1. The consumable box 1 is detachably mounted in the mounting portion 2 of the printing device. The side walls of the box body 10 of the consumable box 1 in the first direction are respectively a front wall 10a and a rear wall 10b, and the front wall 10a is provided with an ink outlet 170. In the second direction N, a recessed portion 110 is formed from the front wall 10a toward a direction away from the front wall 10a. The chip assembly 120 is arranged on the recessed portion 110. The chip assembly 120 includes a chip 121, and the consumable box 1 and the printing device communicate through the contact pins 261 of the printing device and the terminals 1211 of the chip 121. The plane where the chip 121 is located is set to be not orthogonal to or not perpendicular to the plane where the front wall 10a is located. The force acting on the surface of the contact pins 261 of the mounting portion 2 and the terminals 1211 of the chip 121 will be reduced. Therefore, the plane where the chip 121 is located is tilted to reduce the wear on the chip 121 and the contact pin 261, extend the service life of the contact pin 261 and the chip 121, ensure the communication quality between the consumable box 1 and the printing device, extend the service life of the consumable box 1 and the printing device, and improve the user experience.

[0092] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0093] Reference Figure 8 、 Figure 9 and Figure 10 As shown, the plane where chip 121 lies is defined as P1. Plane P1 is not perpendicular to the plane where front wall 10a lies. In other words, plane P1 is not parallel to right wall 10d. Plane P1 is at an angle to right wall 10d. The distance between chip 121 and right wall 10d along the first direction K decreases.

[0094] The plane of the chip 121 forms an angle with the plane of the right wall 10d of the box body 10. The plane of the right wall 10d of the box body 10 is parallel to the plane of the left arm 10c, and the plane of the chip 121 forms an angle with the plane of the left arm 10c. The angle formed by the chip 121 and the right wall 10d of the consumables box can change the force between the chip 121 and the contact pins 261, reducing the force exerted by the contact pins 261 on the surface of the chip 121 in certain areas, thereby reducing wear between the chip 121 and the contact pins 261, improving the reliability and service life of the consumables box 1, and enhancing the user experience.

[0095] Reference Figure 9 and Figure 10 As shown, chip 121 is provided with a contact surface 1210, which is used to contact at least the stylus 261 of the printing device. Contact surface 1210 is the interface for physical contact and data exchange between stylus 261 and chip 121. Contact surface 1210 provides a stable contact platform, ensuring that stylus 261 can accurately and reliably contact chip 121.

[0096] Furthermore, contact surface 1210 is tilted away from front wall 10a and is neither orthogonal nor perpendicular to the plane of front wall 10a. In other words, contact surface 1210 forms a certain angle with right wall 10d along first direction K and faces right wall 10d. This reduces uniform wear between contact pins 261 and chip 121, extending the service life of contact pins 261 and chip 121.

[0097] The contact surface 1210 extends in a direction that forms an angle with the plane of the right wall 10d of the cartridge body 10. The plane of the right wall 10d of the cartridge body 10 is parallel to the plane of the left arm 10c, and the contact surface 1210 extends in a direction that forms an angle with the plane of the left arm 10c. This angle between the contact surface 1210 and the right wall 10d reduces the force exerted by the stylus 261 on the contact surface 1210 in some areas of the contact surface 1210, thereby extending the service life of the contact surface 1210 and the stylus 261 and improving the stability of information communication between the consumable cartridge 1 and the printing device.

[0098] Reference Figure 2 and Figure 8As shown, the contact surface 1210 includes, in order, Area A, Area B, and Area C along a first direction. It is easy to understand that the extension direction of the contact surface 1210 forms an angle with the plane of the right wall 10d of the box body 10, and the distances between Areas A, B, and C and the plane of the right wall 10d increase in sequence. The stylus 261 deforms most in Area A on the contact surface 1210, followed by Area B, and least in Area C. The degree of deformation of the stylus 261 affects the magnitude of the force acting between the contact surface 1210 and the stylus 261. By controlling the degree of deformation, the magnitude of the force can be varied, thereby extending the service life of the contact surface 1210 and the stylus 261.

[0099] Continue to refer to Figure 8 、 Figure 9 and Figure 10 As shown, chip 121 includes multiple terminals 1211, which are located on the end of contact surface 1210 near front wall 10a. Multiple terminals 1211 ensure accurate and reliable data transmission. Positioning multiple terminals 1211 on the end of contact surface 1210 near front wall 10a ensures that when the consumables cartridge is installed, terminals 1211 can immediately mate with contact pins 261, thereby improving communication efficiency and quality.

[0100] The multiple terminals 1211 are arranged in sequence and spaced apart to prevent electromagnetic interference or physical contact between the multiple terminals 1211 from causing data transmission errors or instability, thereby reducing the failure rate.

[0101] In some possible embodiments, multiple terminals 1211 are disposed on the contact surface 1210, and the plane in which the contact portions of the multiple terminals 1211 lie is not orthogonal to or perpendicular to the plane of the front wall 10a. In other words, the multiple terminals 1211 each form a certain angle with the right wall 10d along the first direction K. This reduces uniform wear between the contact pin tips 2610 of the contact pins 261 and the individual terminals 1211, thereby improving the reliability of the terminals 1211.

[0102] The arrangement direction of the multiple terminals 1211 is set perpendicular to the extension direction of the contact surface 1210. The vertical arrangement can more effectively utilize the space on the contact surface 1210, so that more terminals 1211 can be arranged within the limited area of the contact surface 1210.

[0103] For example, the terminal 1211 is configured as a gold finger, which can ensure the stability and reliability of data transmission and reduce wear and tear caused by long-term use.

[0104] The extension direction of the gold finger is parallel to the extension direction of the contact surface 1210. When the stylus is along the installation direction of the consumable box, it can ensure that the contact between the stylus 261 and the gold finger remains stable during movement, and reduce communication problems caused by poor contact or wear.

[0105] As an important component of the consumables box, chip 121 not only includes a terminal 1211 for data transmission, but also integrates a storage element 1212. Storage element 1212 can automatically record and manage consumables information. This improves data processing efficiency and enhances the user experience.

[0106] The storage element 1212 is disposed at the end of the contact surface 1210 that is away from the front wall 10a. In other words, along the first direction, the K terminal 1211 and the storage element 1212 are arranged sequentially. Spatially separating the storage element 1212 from the data transmission terminal 1211 can reduce electromagnetic interference between them, ensuring the stability and accuracy of data transmission. This makes the overall design of the chip 121 more compact and efficient.

[0107] Furthermore, the installation direction of the consumables box 1 is perpendicular to the plane of the front wall 10a, and the angle between the contact surface 1210 and the installation direction of the consumables box 1 is 2 degrees to 30 degrees. In other words, the angle between the contact surface 1210 and the right wall 10d along the first direction K is 2 degrees to 30 degrees. For example, the angle between the contact surface 1210 and the right wall 10d can be 5 degrees, 10 degrees, 15 degrees, 20 degrees, etc.

[0108] Specifically, the included angle between the contact surface 1210 and the right wall 10 d along the first direction K can be set to 8 degrees to 15 degrees.

[0109] Reference Figure 11 、 Figure 12 and Figure 13 As shown, in some other possible embodiments, the chip 121 is smaller in size. One or more of the multiple terminals 1211 are disposed on the contact surface 1210, and the extension direction of the one or more terminals 1211 is the same as the extension direction of the contact surface 1210, which can more effectively utilize the space on the contact surface 1210.

[0110] The storage element 1212 is disposed on the side opposite to the contact surface 1210. If the number of terminals 1211 disposed on the contact surface 1210 does not meet communication requirements, the terminals 1211 can be disposed on the side opposite to the contact surface 1210. This arrangement reduces electromagnetic interference between the storage element 1212 and the terminals 1211, ensuring stable and accurate data transmission. This makes the overall design of the chip 121 more compact and efficient.

[0111] Furthermore, the angle between the contact surface 1210 and the right wall of the box body 10 along the first direction K can be 2 degrees to 30 degrees. The storage element 1212 and the terminal 1211 are disposed on opposite sides of the contact surface 1210, which does not affect the wear between the contact pin tip 2610 of the contact pin 261 and each terminal 1211. Similarly, in this case, the reliability of the terminal 1211 can be improved.

[0112] It is easy to understand that the contact surface 1210 and the side opposite to the contact surface 1210 are provided with a terminal 1211 and a storage element 1212. The angle between the contact surface 1210 and the right wall 10d along the first direction K can be set to 15 degrees to 25 degrees.

[0113] Similarly, if the angle between the contact surface 1210 and the right wall 10d is less than 15 degrees, the stylus 261 will deform minimally during installation of the consumables box 1, failing to reduce wear. If the angle between the contact surface 1210 and the right wall 10d of the box body 10 is greater than 30 degrees, the stylus 261 in contact with the chip 121 will deform significantly at end A, potentially damaging the stylus 261. When the angle is within this range, the stylus 261 maintains good contact with the chip 121, effectively reducing wear and ensuring stable communication quality.

[0114] Reference Figure 14 、 Figure 15 and Figure 16 As shown, when the consumable box 1 is installed, an external force along the first direction K is applied to the consumable box 1, and the guide protrusion 2110 enters from the guide opening 1324 and moves to the vicinity of the second working surface 13233b.

[0115] Reference Figure 7 、 Figure 14 and Figure 17 、 Figure 18 As shown, the guide protrusion 2110 leaves the second working surface 13233b and enters the second groove 13232. At this time, the contact position between the top of the contact pin 2610 and the terminal 1211 changes from end A to end B and then to end C. During this process, the elastic deformation of the contact pin 261 gradually decreases, and the force between the contact pin 261 and the surface of the terminal 1211 of the chip 121 gradually decreases. Therefore, the inclined plane on which the chip 121 is located reduces the degree of wear on the chip 121 and the contact pin 261, extends the service life of the contact pin 261 and the chip 121, ensures the communication quality between the consumables box 1 and the printing device, extends the service life of the consumables box 1 and the printing device, and improves the user experience.

[0116] Reference Figure 7 、 Figure 14 and Figure 19 、 Figure 20As shown, the guide protrusion 2110 leaves the second groove 13232 and is inserted into the third working surface 13233c. At this time, the position where the contact point 2610 of the contact pin contacts the terminal 1211 moves from the C end to the B end. The elastic deformation of the contact pin 261 gradually increases from small to large, and the force between the contact pin 261 and the surface of the terminal 121 of the chip 121 gradually increases from small to large. During this process, the force between the contact pin 261 and the surface of the terminal 121 of the chip 121 is still relatively small. Similarly, such a setting can reduce the degree of wear on the chip 121 and the contact pin 261, extend the service life of the contact pin 261 and the chip 121, ensure the communication quality between the consumable box 1 and the printing device, extend the service life of the consumable box 1 and the printing device, and improve the user experience.

[0117] Similarly, when the consumable box 1 is removed from the printing device, an external force is applied to the consumable box 1 along the first direction K, and the guide protrusion 2110 disengages from the third working surface 13233c of the locking portion 13233 and slides along the side of the boss 13234 until it slides to the first groove 13231. At this time, the deformable member 250 is compressed to generate an elastic force. The position where the contact pin top 2610 contacts the terminal 1211 moves from the B end to the C end. The elastic deformation of the contact pin 261 gradually decreases, and the force between the contact pin 261 and the surface of the terminal 1211 of the chip 121 gradually decreases. During the removal of the consumable box 1, there is no need for communication between the consumable box 1 and the printing device, and the force between the contact pin 261 and the surface of the terminal 1211 of the chip 121 does not need to be very large. The plane where the chip 121 is located is tilted to reduce the wear on the chip 121 and the stylus 261, extend the service life of the stylus 261 and the chip 121, ensure the communication quality between the consumable box 1 and the printing device, extend the service life of the consumable box 1 and the printing device, and improve the user experience.

[0118] Then, the external force applied to the consumables cartridge 1 in the first direction K is removed, and the deformable member 250 generates an elastic force opposite to the compression direction. Under the action of this elastic force, the consumables cartridge 1 moves in the first direction K. The guide protrusion 2110 disengages from the first groove 13231 and reaches the vicinity of the first working surface 13233a of the locking portion 13233. At this point, the contact point between the contact pin tip 2610 and the terminal 1211 moves from end A to end B and then to end C, and the elastic deformation of the contact pin 261 gradually increases.

[0119] Finally, the guide protrusion 2110 exits from the guide opening 1324 along the passage formed by the first working surface 13233a and the first guide wall 1321, and then separates from the guide portion 132. The user can remove the consumable box 1 from the printing device to complete the disassembly of the consumable box 1.

[0120] The consumable box 1 needs to move back and forth during installation and removal. The plane where the chip 121 is located is tilted. The elastic deformation of the contact pin 261 is reduced during some of the installation and removal processes, which can improve the reliability of the contact pin 261 and ensure the communication quality between the consumable box 1 and the printing device.

[0121] refer to Figure 21 、 Figure 22 and Figure 23 As shown, the chip assembly includes a chip frame 122 , which serves as a carrier of the chip 121 and provides a foundation for mounting and fixing the chip 121 .

[0122] The chip holder 122 is also provided with at least one engaging portion 1222, and the recessed portion 110 of the cartridge body 10 is provided with at least one slot 1110. The engaging portion 1222 engages the slot 1110, allowing the chip holder 122 to be mounted on the cartridge body 10. The chip holder 122 is detachably mounted in the recessed portion 110, and by mounting the chip 121 on the chip holder 122, a modular design of the chip 121 is achieved. This design facilitates replacement and maintenance of the chip 121, improving the overall maintainability of the consumable cartridge 1.

[0123] The chip holder 122 has an inclined portion 1221, on which the chip 121 is mounted. When mounted on the inclined portion, the chip 121 forms a certain angle with the front wall 10a of the consumables box. The plane of the inclined portion 1221 is not orthogonal or perpendicular to the plane of the front wall 10a. This reduces uniform wear between the contact pin tips 2610 of the contact pins 261 and the individual terminals 1211, improving the reliability of the terminals 1211.

[0124] Reference Figure 24 As shown, the bottom wall 10e is provided with a first area 130 extending along a first direction K. The bottom wall 10e is also provided with a second area 140 extending along the first direction K. The second area 140 and the first area 130 are arranged sequentially along a second direction N. A guide portion 132 is located in either the first area 130 or the second area 140. The guide portion 132 is spaced a certain distance from the rear wall 10b of the box body 10. Printing devices require frequent replacement of consumable cartridges 1, and the guide portion 132 facilitates accurate and quick installation of the consumable cartridges 1 into the printing device.

[0125] A first clearance area 131 is defined between the guide portion 132 and the front wall 10a of the cartridge body 10. The first clearance area 131 can be a flat or curved area. When the consumable cartridge 1 is installed in the mounting portion of the printing device, the guide protrusions on the mounting portion cooperate with the guide portion 132 to secure the consumable cartridge 1 there. The guide protrusions that engage the guide portion 132 must pass through the first clearance area 131 before entering the guide portion 132. Therefore, the guide portion 132 is higher than the first clearance area 131.

[0126] The second section 140 is provided with a support portion 142, which is used to assist in supporting the consumables cartridge 1, ensuring stability and reliability during printing. The support portion 142 extends from the front wall 10a of the cartridge body 10 to the rear wall 10b. The support portion 142 is located on the bottom wall 10e of the cartridge body 10. The bottom end surface of the support portion 142 is flush with the bottom end surface of the guide portion 132, which makes the bottom end surface of the support portion 142 higher than the first spaced-apart section 131.

[0127] A second spaced-apart area 141 is defined within the second region 140 of the bottom wall 10e of the consumables box. The second spaced-apart area 141 extends from the front wall 10a to the rear wall 10b of the box body 10. In the third direction H, the second spaced-apart area 141 is substantially flush with or slightly higher than the first spaced-apart area 131. This prevents the consumables box 1 from tilting, which could lead to installation delays, inability to properly install, or even damage to the printer or ink cartridge components. This reduces the difficulty of installing the consumables box and improves installation efficiency.

[0128] The second spaced area 141 can also be a flat or curved area. The second spaced area 141 can be improved upon the original consumables box 1 by machining the second spaced area 141 within the second region 140. This can reduce the weight of the consumables box 1 without affecting its usability, and the machining process is simple and easy to operate.

[0129] Along the third direction H, the projections of the first and second clearance areas 131 and 141 at least partially overlap. When the guide protrusion 2110 passes through the first clearance area 131, the second clearance area 141 is slightly higher than or substantially flush with the first clearance area 131 along the third direction H. This arrangement completely prevents the consumable box 1 from being tilted during installation, which could cause installation problems. This reduces the difficulty of installing the consumable box 1 and improves the operability and efficiency of installing the consumable box 1 into the installation portion 2.

[0130] Reference Figure 25 As shown, in addition to the guide opening 1324 provided on the guide portion 132, a side entrance 1325 is also provided on the second guide wall 1322. The side entrance 1325 extends through both sides of the second guide wall 1322. The guide opening 1324 extends obliquely from one end of the guide portion 132 toward the second area 140. In addition to being able to enter the guide groove 1323 through the guide opening 1324, the guide protrusion 2110 can also enter the guide groove 1323 through the side entrance 1325. This prevents the consumable cartridge 1 from getting stuck, improves the compatibility of the consumable cartridge with the printing device, and enhances the user experience.
