In the third direction, the first spaced part 110 is located on the upper side of the first adapter part 825 and does not contact the first adapter part 825, the first non-spaced part 130 and a part of the second area 200 are located on the upper side of the second adapter part 812 and do not contact the second adapter part 812, and another part of the second area 200 is located on the upper side of the third adapter part 826 and does not contact the third adapter part 826.

[0098] The partition 140 is recessed toward the inside of the box body 10 , so that a step is formed between the partition 140 and the first area 100 .

[0099] It should be noted that, along the second direction, the projections of the first partition 110 and the second area 200 at least partially overlap; in the third direction, the height of at least a portion of the surface of the first partition 110 is slightly higher than or equal to the height of a portion of the surface of the second area 200 close to the front panel 13. Compared with some solutions, the height of the surface of a portion of the second area 200 close to the front panel 13 of the consumable box is higher than the height of the first partition 110 in the first area 100, which effectively avoids the problem of the consumable box installation center of gravity shifting due to the height difference between the first area 100 and the second area 200 of the bottom panel 11 of the consumable box when the consumable box is loaded into the printing device, thereby causing the consumable box to interfere with the installation, jam, and fail to install in place.

[0100] The bottom wall of the box body 10 further includes at least one inner enclosure wall 150 , which is configured to protrude from the bottom panel 11 along the third direction.

[0101] In this embodiment, the number of inner enclosure walls 150 is preferably two, and the two inner enclosure walls 150 are spaced apart from each other on the outside of at least a portion of the first non-spaced portion 130 in the first area 100 and at least a portion of the second area 200 close to the rear panel 14, that is, in the opposite direction of the first direction, the two inner enclosure walls 150 are both located on the rear side of the guided portion 20.

[0102] The first area 100 and the second area 200 are provided with a partition 140, and the two inner enclosure walls 150 and a part of the outer enclosure wall 160 together form a semi-enclosed space 151, a part of the partition 140 extends into the space 151, and another part of the partition 140 is located outside the space 151. The partition 140 is configured to extend from a position on the bottom panel 11 adjacent to the front panel 13 to a position close to the rear panel 14.

[0103] refer to Figure 3 , Figure 4 and Fig. 9 As shown, in the first direction, the spacer 140 has an opening 141 on one side close to the front panel 13. When the consumable box is installed in the mounting portion 84 of the printing device, the guide rib 831 in the printing device enters the spacer 140 from the opening 141. After the consumable box is displaced through the third position in the mounting portion 84 of the printing device, that is, after the fluid interface portion 131 in the consumable box is engaged with the interface unit 822 in the mounting portion 84, the guide rib 831 enters the space portion 151. When the consumable box is installed in or removed from the mounting portion 84, the guide rib 831 does not contact the spacer 140 and the inner enclosure wall 150. When the consumable box is completely installed in the mounting portion 84, the guide rib 831 is located in the space portion 151.

[0104] The peripheral barrier wall 160 surrounds the bottom panel 11 and is connected to the rear panel 14 . Each of the two inner barrier walls 150 is configured to have one end connected to the peripheral barrier wall 160 and the other end away from the rear panel 14 in the opposite direction of the first direction.

[0105] The distance between the end of the inner enclosure wall 150 of the first area 100 and the end of the inner enclosure wall 150 of the second area 200 away from the rear panel 14 and the rear panel 14 is D1, and the range of D1 is 0≤D1≤33 mm.

[0106] In this embodiment, the shape of the opening 141 is a trumpet shape, and in the direction opposite to the first direction, the opening 141 extends from one end close to the front panel 13 to a position close to the guided portion 20. In the second direction, the width of the opening 141 is greater than the width of the remaining spacers 140 except the opening 141. The spacers 140 or the opening 141 may also be configured as other structures for adapting to different consumable boxes.

[0107] It should be noted that, in this embodiment, in the second direction, the guide portion 22 is closer to the locking portion 23 than the spacing portion 140 .

[0108] In the prior art, if the user adopts an irregular installation method when installing the consumable box into the printing device, the guide protrusion 811 may enter the first entrance 251, and the guide protrusion 811 with a sheet-like strip structure may be blocked by the two protrusions 211 arranged opposite to each other at the first entrance 251 due to the angle deviation, so that the consumable box cannot be correctly installed in the installation part 84 of the printing device, and even the guide protrusion 811 may be damaged. Figure 7 and Figure 8 As shown, the present application sets a notch 27 so that the guide protrusion 811 is not easily blocked or stuck when entering the locking path 254 .

[0109] In the second direction, the locking path 254 and the unlocking path 255 are arranged opposite to each other. In the opposite direction of the first direction, the locking path 254 and the unlocking path 255 are both constructed with one end starting from the first entrance 251 and the other end extending toward the intersection path 256 .

[0110] In the direction opposite to the first direction, the guide portion 22 and the locking portion 23 are sequentially arranged relative to the first entrance 251 . Compared with the guide portion 22 , the locking portion 23 is farther away from the first entrance 251 , and the guide portion 22 is configured to be inclined toward the direction close to the locking portion 23 .

[0111] The locking portion 23 is located between the locking path 254 and the unlocking path 255, wherein the locking portion 23 includes a first surface 231, a locking surface 232 and a second surface 233, and the first surface 231, the locking surface 232 and the second surface 233 together form the locking portion 23. The surface of the locking portion 23 facing the locking path 254 is the first surface 231, the surface facing the unlocking path 255 is the second surface 233, and the surface facing the intersecting path 256 is the locking surface 232.

[0112] The limiting boss 26 has a first clamping portion 261 and a second clamping portion 263 therein. The first clamping portion 261 and the second clamping portion 263 are spaced apart and located at one side of the guided portion 20 close to the first non-spaced portion 130 .

[0113] In the first direction, the first clamping portion 261 and the second clamping portion 263 are farther away from the first entrance 251 than the locking portion 23. The limiting boss 26 also includes a separation portion 262, which is located between the first clamping portion 261 and the second clamping portion 263. In this embodiment, the first clamping portion 261 and the second clamping portion 263 are configured as a card slot structure, and can also be configured as other structures for adapting to the guided portion 20 and the guide portion 81 in the printing device.

[0114] The limiting boss 26 further includes a guide block 264 , and the guide block 264 has a second inclined surface 2641 .

[0115] The isolation portion 262 has a first inclined surface 2621, which is inclined toward the first clamping portion 261. In this embodiment, by providing the guide portion 22, the movement trajectory of the guide protrusion 811 in the locking path 254 can be limited, thereby realizing the posture correction of the consumable box during the installation process, so that the guide protrusion 811 can move along the correct installation path to contact the second inclined surface 2641, and is guided into the first clamping portion 261 by the second inclined surface 2641, thereby improving the operability and accuracy of the consumable box installation process.

[0116] Along the second direction, the locking path 254 is located at a side close to the second area 200 , and the unlocking path 255 is located at a side away from the second area 200 . The locking path 254 and the unlocking path 255 intersect and connect to an intersecting path 256 .

[0117] When the consumables box is loaded into the first position of the installation unit 80, the guide portion 81 enters the guided portion 20 and guides the consumables box to move toward the second position;

[0118] When the consumables box reaches the second position, the guiding inclined surface 852 contacts the guided surface 171 at the edge of the second mounting portion 17 and guides the consumables box to move toward the third position;

[0119] When the consumables box reaches the third position, the fluid interface portion 131 engages with the interface unit 822 .

[0120] The process of installing the consumables box into the printing device is as follows. Figure 7 , Figure 8 and Fig.11As shown, the consumable box is applied with an external force in the opposite direction to the first direction, and enters the mounting portion 84 in the opposite direction to the first direction. When the guide protrusion 811 in the guide portion 81 passes through the first spaced portion 110 and reaches the first position of the mounting portion, the guide protrusion 811 reaches the first entrance 251 of the guided portion 20, and enters the guided portion 20 from the first entrance 251. It should be noted that during the whole process, the guide protrusion 811 does not contact the first spaced portion 110, and the guide rib 831 enters the spaced portion 140 from the opening 141 without contacting the spaced portion 140.

[0121] refer to Figure 7 , Figure 8 and Fig.12 As shown, after the guide protrusion 811 enters the slide groove 25 from the notch 27 on one side of the first entrance 251, Figure 7 , Figure 8 and Fig.13 As shown, the guide portion 81 swings a certain angle around the movable shaft 824, so that the guide protrusion 811 enters the locking path 254, and the guide protrusion 811 moves along the locking path 254 to between the guide portion 22 and the locking portion 23. The guide portion 22 drives the guide protrusion 811 to deviate toward the locking portion 23, and causes the guide protrusion 811 to move along the first surface 231 of the locking portion 23. When the guide protrusion 811 moves to disengage from the first surface 231 and enter the intersection path 256, the consumable box moves to the second position in the mounting portion 84. At this time, the guided surface 171 at the edge of the second mounting portion 17 of the consumable box is in contact with and guided by the guide slope 852 of the contact pin assembly 85, prompting the consumable box to move toward the third position of the mounting portion 84.

[0122] As the consumable box continues to move toward the third position, the electrical interface component 18 is electrically connected to the contact pin 851 of the contact pin assembly 85. When the consumable box moves to the third position, the ink outlet 1311 and the inflation hole 1312 of the consumable box are pre-engaged with the ink supply portion 8222 and the inflation portion 8221 in the mounting portion 84 respectively, and the deformable member 823 surrounding the ink supply portion 8222 contacts the front panel 13 of the consumable box and begins to deform. After the consumable box passes the third position of the mounting portion 84, the guide rib 831 enters the space portion 151, but the guide rib 831 does not contact the space portion 151.

[0123] refer to Figure 8 , Fig.14 , Fig.15 and Fig.16As shown, as the consumable box continues to move from the third position toward the target installation position, the guide protrusion 811 moves to contact the second inclined surface 2641, and is guided by the second inclined surface 2641 to enter the second clamping portion 263 adjacent to the second area 200. At this time, the deformation of the deformable part 823 arranged around the periphery of the ink supply portion 8222 is the largest, and the ink outlet 1311 and the inflation hole 1312 of the consumable box are fully engaged with the ink supply portion 8222 and the inflation portion 8221 in the installation portion 84, respectively.

[0124] Then, the external force acting on the consumable box is cancelled, and the consumable box moves in the opposite direction to the first direction under the action of the deformation force of the deformable member 823, and the guide protrusion 811 is separated from the second clamping portion 263, and falls on the locking surface 232, slides along the locking surface 232, and finally falls into the recessed portion 234, thereby completing the installation of the consumable box. During the whole process, the guide rib 831 does not contact the spacing portion 140 and the space portion 151.

[0125] refer to Fig.17 As shown, when the consumable box is fully loaded into the mounting portion 84, the guide rib 831 is located in the spacer portion 140, a portion of the outer retaining wall 160 is supported on the second adapter portion 812 and the third adapter portion 826, and in the first direction, the first partition portion 110 is located on the upper side of the first adapter portion 825 and is not in contact with the first adapter portion 825, and the first non-partition portion 130 and a portion of the second area 200 are located on the upper side of the second adapter portion 812 and are not in contact with the second adapter portion 812.

[0126] refer to Figure 8 , Fig.10 , Fig.18 and Fig.19As shown, with the use of the consumable box, the ink stored in the consumable box is completely consumed, and the user needs to remove the consumable box from the mounting portion 84. Specifically: a force is applied to the consumable box along a first direction, and the guide protrusion 811 in the guide portion 81 slides from the recessed portion 234 along the other inclined surface of the locking surface 232 to disengage from the locking surface 232 and enter the intersection path 256. As the consumable box continues to move, the guide protrusion 811 contacts the isolation portion 262 located in the intersection path 256, and moves along the first inclined surface 2621 of the isolation portion 262 and enters the first clamping portion 261 away from the second area 200. At this time, the deformable member 823 arranged around the periphery of the ink supply portion 8222 contacts the front panel 13 of the consumable box and is compressed. At this time, the external force is removed and the consumable box is no longer pressed. The consumable box is displaced in the opposite direction of the first direction under the action of the deformation force restored by the deformable member 823, so that the guide protrusion 811 disengages from the first clamping portion 261 and enters the unlocking path 255, and contacts the second surface 233 of the locking portion 23, and displaces along the second surface 233 until it disengages from the unlocking path 255 and enters the first entrance 251, the electrical interface component 18 is disconnected from the contact pin 851, and the guide rib 831 is disengaged from the space portion 151 and the spacer portion 140. After that, the user can remove the consumable box from the printing device to complete the disassembly of the consumable box.

[0127] During the whole process, the guiding rib 831 does not contact the spacing portion 140 or the space portion 151 .

[0128] Compared with the solutions in the prior art, the technical solution provided by this embodiment can effectively solve the problem that when the user installs the consumable box into the printing device, due to the use of an irregular installation method, the guide protrusion 811 has an entry angle deviation during the process of entering the first entrance 251, resulting in the guide protrusion 811 in a sheet-like long strip structure being blocked by the two first blocking parts 21 arranged opposite to the first entrance 251, and the consumable box cannot be correctly installed in the installation part 84 of the printing device, and even causes damage to the guide protrusion 811. At the same time, by providing a guide part 22 at a position adjacent to the locking part 23 in the locking path 254, the path of the guide protrusion 811 moving in the locking path 254 can be limited, and the posture of the consumable box during the installation process can be corrected, so that the guide protrusion 811 can move along the correct installation path to contact the second inclined surface 2641, and be guided by the second inclined surface 2641 to enter the corresponding clamping part 261, thereby improving the operability and accuracy of the consumable box installation process.

[0129] In addition, refer to Figure 7 and Figure 8As shown, by limiting the size and structure of the inner enclosure wall 150 and the spacer 140, the guide rib 831 is prevented from contacting the inner enclosure wall 150 and the spacer 140 when the consumable box is installed in or removed from the installation part 84, thereby avoiding the problem in the prior art that the user fails to accurately align the guide rib 831 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 831 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.

[0130] Embodiment 2:

[0131] Different from the first embodiment, in this embodiment, reference Figure 7 and Figure 8 As shown, a side of the slide groove 25 opposite to the first blocking portion 21 has a bypass entrance 252 , the bypass entrance 252 is located between the guide portion 22 and the limiting boss 26 , and the bypass entrance 252 is communicated with the locking path 254 .

[0132] In a possible implementation, in the second direction, the guide portion 22 is closer to the locking portion 23 than the bypass inlet 252 .

[0133] In one possible implementation, the outer bottom wall of the box body 10 has a first area 100 and a partition 140 adjacent to each other, the guided portion 20 is located in the first area 100, and the partition 140 is recessed toward the inside of the box body 10 so that a step is formed between at least part of the partition 140 and the first area 100; at least part of the side wall of the partition 140 is a guiding slope 253 inclined toward the side inlet 252.

[0134] In a possible implementation, the limiting boss 26 further includes a guide block 264 having a second inclined surface 2641 , and along the extension direction of the bypass inlet 252 , the second inclined surface 2641 is inclined from the bypass inlet 252 toward the limiting boss 26 , specifically, toward the second clamping portion 263 .

[0135] The side entrance 252 is located on the side of the guided portion 20 close to the second area 200. For example, when the user is installing the consumable box into the printing device, due to the skewed installation posture of the ink cartridge, the guide protrusion 811 of the guide portion 81 swings too much around the movable axis 824, resulting in the guide protrusion 811 not entering the first entrance 251 of the guided portion 20 from the first spacer portion 110, but displacing to the spacing portion 140 between the first area 100 and the second area 200. At this time, the guide protrusion 811 can also re-enter the locking path 254 through the side entrance 252, contact the second inclined surface 2641, and be guided by the second inclined surface 2641 to enter the clamping portion 261 adjacent to the second area 200.

[0136] The side entrance 252 is provided with a guide slope 253, so that the guide protrusion 811 can fall into the unlocking path 255 along the guide slope 253. The side of the guide portion 22 facing the side entrance 252 has a third guide surface 223, which is a slope.

[0137] The technical solution provided in this embodiment can effectively solve the problem that when the consumable box is installed into the printing device, the installation position of the consumable box is offset due to the user's improper installation, causing one end of the guide protrusion 811 to mistakenly enter the spacing portion 140 between the first area 100 and the second area 200, causing interference with the installation of the consumable box or causing damage to the guide protrusion.

[0138] 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.

[0139] It should be noted that, if the consumable box is installed in a standard manner, this embodiment can also adopt the method of installing the consumable box into the printing device in the first embodiment.

[0140] 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.

[0141] It should be noted that, if the consumable box is installed in a standard manner, this embodiment can also adopt the method of installing the consumable box into the printing device in the first embodiment.

[0142] It should be noted that the maximum swing angle of the guide protrusion 811 around the movable axis 824 is the angle required for the guide protrusion 811 to enter the spacing portion 140 provided between the first area 100 and the second area 200 .

[0143] Embodiment three:

[0144] This embodiment 3 is different from the embodiment 1. Fig. 20As shown, one side panel 15 of the box body 10 is provided with at least one protrusion 30, and the protrusion 30 is located adjacent to the bottom panel 11 or the top panel 12. Alternatively, at least one protrusion 30 may be provided on both side panels 15 of the box body 10.

[0145] When the consumable box is installed into the mounting portion 84, the two outer protrusions 30 provided on the two side panels 15 adjacent to the bottom panel 11 respectively abut against the side walls of the frame 83 and the guide ribs 831 provided in the adjacent mounting portion 84. If the user installs the consumable box in an irregular manner, it is convenient to correct the installation posture of the consumable box.

[0146] When the consumable box is installed into the mounting portion 84, the two outer protrusions 30 are respectively abutted against the side walls of the frame 83 and the guide ribs 831 provided in the adjacent mounting portion 84, so as to prevent the consumable box from being accidentally subjected to the force in the second direction during the installation process, causing shaking, and then colliding with the guide ribs 831, causing damage to the guide ribs 831.
