DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] refer to Figure 1 As shown, in the related art, the outer bottom wall of the consumable box is divided into a first area 30 and a second area 40 arranged in an interval manner, and in the length direction of the consumable box, the extension directions of the first area 30 and the second area 40 are parallel to each other. A guided portion 20 is provided in the first area 30, and the guided portion 20 is used to cooperate with the guide portion 81 in the mounting portion 84 of the printing device to guide the consumable box to be installed in the mounting portion 84.

[0047] In the width direction, some consumable boxes are wider, such as the consumable box storing black ink, so a matching rib 831 is provided at the middle position of the entrance of the mounting portion corresponding to the mounting unit. In order to avoid this matching rib 831, a groove portion 50 is usually provided on the outer bottom wall of the consumable box.

[0048] However, when installing the consumable box into the mounting portion 84 of the mounting unit 80 of the printing device, the front panel 13 of the consumable box is likely to interfere with or collide with the mating rib 831, causing the consumable box to be unable to be installed smoothly. In addition, the ink accidentally leaked from the ink outlet 1311 may reach the groove 50. As the consumable box is installed into the mounting portion 84 of the mounting unit 80 of the printing device, the ink in the groove 50 may reach the rear panel 14 or the mounting portion 84 of the box body 10 of the consumable box under the push of the mating rib 831, causing the leaked ink to contaminate the user's hands or cause other printing problems. Among them, the rear panel 14 is the exposed surface of the consumable box. The user needs to touch the rear panel 14 during the process of installing or removing the consumable box, which is also likely to cause the problem of ink contaminating the user's fingers.

[0049] The consumables box provided by the embodiment of the utility model is described below with reference to the accompanying drawings.

[0050] refer to Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a consumables box, which can be detachably mounted on a mounting unit 80 of a printing device. The mounting unit 80 has a mounting portion 84 for accommodating the consumables box, and the bottom wall of the mounting portion 84 is provided with a matching rib 831.

[0051] The mounting unit 80 has a mounting portion 84, and ink is stored in the consumable box. During printing, the ink is output to the ink supply portion 8222 in the mounting portion 84. The ink supply portion 8222 supplies the ink to the print head, and the print head sprays the ink onto the printing medium to form text or patterns. The printing medium may be, for example, paper.

[0052] refer to Figure 5 and Figure 7 As shown, the utility model provides a consumable box including: a box body 10, the outer bottom wall of the box body 10 has a first area 30 and a second area 40 arranged along a first direction, the outer bottom wall of the box body 10 also has a groove portion 50, the groove portion 50 is located between at least a portion of the first area 30 and at least a portion of the second area 40, the groove portion 50 includes a storage area 51, and a blocking portion 70 is arranged between the storage area 51 and the second area 40, and a side of the blocking portion 70 facing the storage area 51 is a guiding inclined surface 71, and the guiding inclined surface 71 is used to guide the movement of the matching rib 831 during the installation of the consumable box;

[0053] Along the installation direction of the consumable box: the front end of the box body 10 has a front panel 13, the first end of the blocking portion 70 extends to the front panel 13, and the guiding slope 71 is inclined in the direction away from the first area 30; wherein, there is an angle between the installation direction of the consumable box and the first direction.

[0054] refer to Figure 3 and Figure 7As shown, the utility model provides a consumable box, by setting a guiding slope 71 on a side of the blocking portion 70 facing the storage area 51, when the consumable box is installed on the installation unit 80 of the printing device, the guiding slope 71 guides the matching rib 831, so that the matching rib 831 is easy to align with the storage area 51 to enter to realize the installation of the consumable box, so that during the installation process of the consumable box, there is a certain tolerance for the position of the consumable box entering the installation portion 84 of the installation unit 80, even if the consumable box is not completely and accurately aligned with the position of the installation portion 84, it will not affect the correct installation of the consumable box.

[0090] In one possible implementation, the limiting boss 26 has a first clamping portion 261 and a second clamping portion 263, and the limiting boss 26 also includes an isolation portion 262 blocking the first clamping portion 261 and the second clamping portion 263, the opening of the first clamping portion 261 faces the unlocking path 255, and the opening of the second clamping portion 263 faces the intersection path 256.

[0091] refer to Figure 5 and Figure 6 As shown, the first clamping portion 261 and the second clamping portion 263 are located in a spaced manner on one side of the guided portion 20 close to the first non-spaced portion 32. 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 to adapt to the structure of the guide portion 81 in the printing device. The side of the isolation portion 262 facing the locking portion 23 is a first inclined surface 2621, and along the installation direction of the consumable box, the first inclined surface 2621 is inclined from the first clamping portion 261 to the second clamping portion 263.

[0092] In the second direction, compared with the first space portion 31 , the groove portion 50 is farther away from the ink outlet 1311 . In this example, the groove portion 50 is constructed as a semi-closed structure.

[0093] refer to Figure 5 and Figure 6As shown, along the second direction, the first non-spaced portion 32, the guided portion 20 and the first spaced portion 31 are arranged in sequence, and the guided portion 20 is located between the first non-spaced portion 32 and the first spaced portion 31. Compared with the guided portion 20, the first non-spaced portion 32 is located in the first area 30 at a position farther away from the ink outlet 1311, and the first spaced portion 31 is located in the first area 30 at a position closer to the ink outlet 1311.

[0094] refer to Figure 3 , Figure 5 and Figure 6 As shown, when the consumable box containing black ink is installed in the installation part 84, the guided part 20 is engaged with the guide part 81, and the second enclosure part 41 and a part of the second baffle 34 are supported on the second adapter part 812 and the third adapter part 826. In the third direction, the first spaced part 31 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 32 and a part of the second area 40 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 40 is located on the upper side of the third adapter part 826 and does not contact the third adapter part 826.

[0095] refer to Figure 7 As shown, the second region 40 includes a second non-spaced portion 42 . In the second direction, a portion of the storage area 51 and the second non-spaced portion 42 are arranged in sequence. Compared with the second non-spaced portion 42 , the storage area 51 is closer to the ink outlet 1311 .

[0096] refer to Figure 2 and Figure 3 As shown, in this embodiment, the black ink consumable cartridge is wider than the other color ink consumable cartridges, and thus, the mounting portion 84 for mounting the black ink consumable cartridge is wider than the mounting portion 84 for mounting the other color ink consumable cartridges.

[0097] In the second adapter portion 812 , the sub-adaptation position 813 in the installation position of the black ink consumable box is wider, and a matching rib 831 is provided in the middle of the sub-adaptation position 813 , and the second non-spaced portion 42 matches with the sub-adaptation position 813 in the second adapter portion 812 .

[0098] The storage area 51 can accommodate ink accidentally leaked from the ink outlet 1311. The storage area 51 is located on the -X axis side of the ink outlet 1311 and the storage area 51 is located on the -X axis side of the first space 31. Along the installation direction of the consumable box, the guide slope 71 is inclined toward the +X axis and +Y axis directions.

[0099] When the consumable box containing black ink is loaded into the mounting portion 84 , the storage area 51 and a portion of the second non-spaced portion 42 correspond to the third adapter portion 826 , and another portion of the second non-spaced portion 42 corresponds to a portion of the sub-adaptation position 813 in the second adapter portion 812 .

[0100] It should be noted that, in the first direction, the first space portion 31 is disposed adjacent to the storage area 51 .

[0101] The utility model provides a storage area 51, so that when the consumable box is installed on the installation portion 84, the problem of interference and collision between the front panel 13 and the matching rib 831 and other problems that make it difficult to install smoothly is reduced; the storage area 51 can be used to accommodate ink, which reduces the possibility that ink may reach the rear panel position of the box body 10 or reach the outside of the installation portion 84 along the groove portion 50, which helps to reduce the occurrence of ink contamination caused by ink dripping onto other parts of the printer.

[0102] refer to Figure 4 , Figure 6 , Figure 7 As shown, when the consumable box is loaded into the mounting portion 84, an external force is applied to the consumable box along the second direction, the mating rib 831 enters the storage area 51, and then slides along the groove portion 50 into the partition area 52. When the consumable box is completely loaded into the mounting portion 84, the mating rib 831 cooperates with the groove portion 50. In addition, the guide protrusion 811 in the guide portion 81 passes through the first partition portion 31 and reaches the first entrance 21 of the guided portion 20, and enters the guided portion 20 from the first entrance 21.

[0103] It should be noted that after the matching rib 831 enters the storage area 51, the guide protrusion 811 begins to contact the first spaced portion 31. As the consumable box moves, the guide protrusion 811 leaves the first spaced portion 31 and enters the guided portion 20 from the first entrance 21. At this time, 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 moves to contact the first surface 231 of the locking portion 23. The guide protrusion 811 moves along the first surface 231 of the locking portion 23. After being displaced from the first surface 231 and until the guide protrusion 811 enters the intersection path 256, the guide protrusion 811 enters from the intersection path 256 into the second clamping portion 263 adjacent to the second non-spaced portion 42. At this time, the deformable member 823 arranged around the periphery of the ink supply portion 8222 contacts and is compressed by the front panel 13 of the consumable box. The deformation amount of the deformable member 823 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 mounting portion 84, respectively.

[0104] Then, the external force acting on the consumable box is removed, and the consumable box moves in a direction opposite to the second direction under the action of the deformation force restored by the deformation member 823. The guide protrusion 811 disengages from the second clamping portion 263, falls onto 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.

[0105] When the consumable box 1 is completely loaded into the mounting portion 84, the mating rib 831 abuts against the closed end of the groove portion 50, that is, it abuts against the end of the partition area 52 away from the storage area 51, the first partition portion 31 corresponds to the first adapter portion 825, the first non-partition portion 32 corresponds to the second adapter portion 812, the storage area 51 and a part of the second non-partition portion 42 correspond to the third adapter portion 826, and another part of the second non-partition portion 42 corresponds to the sub-adaptation position 813 of the second adapter portion 812.

[0106] As the consumable box is used, the ink stored in the consumable box is exhausted, and the user needs to remove the consumable box from the mounting portion 84. Specifically, a force is applied to the consumable box in the opposite direction to the second direction, and the guide protrusion 811 of 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 of the limiting boss 26, and moves along the first inclined surface 2621 of the isolation portion 262 and enters the first clamping portion 261 away from the second non-isolated portion 42. At this time, the surrounding The deformable member 823 arranged around the periphery of the ink supply portion 8222 contacts the front panel 13 of the consumable box, and the deformable member 823 is compressed. When the external force is removed, the consumable box is no longer pressed. Under the action of the deformation force restored by the deformable member 823, the consumable box is displaced in the opposite direction to the second direction, so that the guide protrusion 811 disengages from the first clamping portion 261 and enters the unlocking path 255, and the guide protrusion 811 contacts the second surface 233 of the locking portion 23, and displaces along the second surface 233 to disengage from the unlocking path 255, and escapes from the first entrance 21. The user can then remove the consumable box from the printing device to complete the disassembly of the consumable box.

[0107] Among other possible implementations, see Fig.10 As shown, no partition plate 60 is provided between the groove portion 50 and the second area 40, and a first baffle plate 33 is provided between the groove portion 50 and the first area 30. The first end of the blocking portion 70 extends to the front panel 13, and the second end of the blocking portion 70 can limit the matching rib 831, and can play a limiting role in the process of installing the consumable box to the installation portion 84.

[0108] Such a structure can also guide the mating rib 831 when the consumable box is installed in the installation unit 80 of the printing device, so that the mating rib 831 is aligned with the storage area 51 to achieve the installation of the consumable box, so that during the installation of the consumable box, there is a certain error tolerance for the position of the consumable box entering the installation portion 84 of the installation unit 80. It should be noted that the consumable box provided by the utility model includes a first area 30 and at least one second area 40 of the outer bottom wall, preferably a consumable box for storing black ink.
