[0045] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0047] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like 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 communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0050] As described in the background art, when the printer shakes or tilts, the ink cartridge is easy to fall off from the installation part of the printer, causing damage to the ink cartridge. The inventors have found that the reason for this problem is that when the printer shakes or tilts, there is no protrusion on the groove of the ink cartridge to prevent the installation part of the printer from being moved, and the protrusion is easy to break away from the groove, so that the ink cartridge is easy to fall off from the installation part of the printer, causing damage to the ink cartridge.

[0051] In order to solve the above problems, an embodiment of the utility model provides a liquid box, which can prevent the protrusion of the printer from escaping from the groove by setting a locking surface parallel to the front surface, so that when the printer shakes or tilts, the liquid box is not easy to fall off from the installation part of the printer, thereby avoiding damage to the liquid box.

[0052] The liquid box provided by the embodiment of the utility model is described in detail below in conjunction with specific embodiments.

[0053] The embodiment of the utility model provides a liquid box, which can be installed in the installation part of the printer, and the bottom surface of the installation part has a movable protrusion 100. Specifically, Figure 1 and Figure 2As shown, a swing rod 200 is provided on the bottom surface of the mounting portion, one end of the swing rod 200 is rotatably connected to the bottom surface of the mounting portion, and a rotatable circular protrusion 100 is provided on the other end of the swing rod 200. The swing rod 200 is equipped with a tension spring 300, one end of the tension spring 300 is fixedly connected to the swing rod 200, and the other end of the tension spring 300 is fixedly connected to the bottom surface of the mounting portion.

[0054] like Figure 3 As shown, the liquid box includes a shell 10 and a groove 20; the shell 10 has a bottom surface 101 and a front surface 103, and the shell 10 has a liquid storage cavity for storing liquid; the groove 20 is arranged on the bottom surface 101 of the shell 10, and the groove 20 has a port 201 facing the front surface 103, and the port 201 can be entered by the protrusion 100; a locking surface 221 parallel to the front surface 103 is arranged in the groove 20 (see Figure 6 As shown), the locking surface 221 is configured to inhibit the protrusion 100 from disengaging from the groove 20.

[0055] The liquid cartridge may be an ink cartridge for storing ink, a storage box for accommodating a liquid bag, or a storage box for accommodating waste liquid disposed in a printer.

[0056] Among them, Figure 4 As shown, a rectangular coordinate system is established for the liquid box. The length direction of the liquid box is the X-axis direction, the width direction of the liquid box is the Y-axis direction, and the height direction of the liquid box is the Z-axis direction. The X-axis, Y-axis and Z-axis are perpendicular to each other.

[0057] The surface of the shell 10 facing the +X axis direction is the front surface 103, and the surface of the shell 10 facing the -X axis direction is the rear surface 104; the surface of the shell 10 facing the +Y axis direction is the left surface 105, and the surface of the shell 10 facing the -Y axis direction is the right surface 106; the surface of the shell 10 facing the -Z axis direction is the bottom surface 101, and the surface of the shell 10 facing the +Z axis direction is the top surface 102.

[0058] like Figure 5 As shown, the liquid box further comprises a containing body 30, and the containing body 30 has a containing cavity for containing liquid.

[0059] The housing 10 is configured in a square shape and has a liquid storage chamber in which the receiving body 30 is placed.

[0060] The top of the housing 10 is openable, that is, the side of the housing 10 facing the +Z axis direction is openable, that is, the receiving body 30 can be placed in the housing 10 from the top of the housing 10 .

[0061] The housing 10 is provided with an ink outlet tube 11, and the container 30 supplies ink to the ink needle 400 (see Figure 1as shown) to supply ink.

[0062] The housing 10 is also provided with a chip 12, which can be connected to the electrical contacts 500 (see Figure 1 As shown), that is, the liquid box communicates with the installation part of the printer through the chip 12.

[0063] like Figure 6 As shown, a portion of the bottom surface 101 of the housing 10 is recessed toward the +Z axis direction to form a groove 20 .

[0064] The port 201 of the groove 20 is flush with the front surface 103 . It can be understood that the port 201 penetrates the front surface 103 in the +X axis direction.

[0065] When the liquid cartridge is installed into the mounting portion of the printer along the +X axis direction, the protrusion 100 enters the interior of the recess 20 from the port 201 of the recess 20 .

[0066] The liquid box provided in the embodiment of the utility model can inhibit the protrusion 100 of the printer from being separated from the groove 20 by setting a locking surface 221 parallel to the front surface 103, so that when the printer shakes or tilts, the liquid box is not easy to fall off from the installation part of the printer, thereby avoiding damage to the liquid box.

[0067] In a possible implementation, the groove 20 includes a plurality of sliding segments, and the plurality of sliding segments are intersected and connected in sequence, that is, the groove 20 is a non-linear groove.

[0068] The protrusion 100 can slide in the sliding section of the groove 20 .

[0069] The number of sliding segments can be three. Specifically, Figure 6 As shown, the groove 20 includes a first sliding section 21, a second sliding section 22 and a third sliding section 23, the port 201 is arranged on the first sliding section 21, the extension direction of the first sliding section 21 is inclined to the length direction of the liquid box, that is, the extension direction of the first sliding section 21 intersects with the length direction of the liquid box, the extension direction of the third sliding section 23 is parallel to the length direction of the liquid box, and the second sliding section 22 intersects and connects with the first sliding section 21 and the third sliding section 23 respectively.

[0070] The extension direction of the second sliding section 22 may be parallel to the width direction of the liquid box. In other embodiments, the extension direction of the second sliding section 22 may also be inclined to the width direction of the liquid box, that is, the extension direction of the second sliding section 22 intersects with the width direction of the liquid box.

[0071] In a possible implementation, Figure 6 As shown, the surface of the second sliding section 22 parallel to the front surface 103 is a locking surface 221 .

[0072] The length of the locking surface 221 in the width direction of the liquid box may be equal to the radius of the protrusion 100. In other embodiments, the length of the locking surface 221 in the width direction of the liquid box may also be slightly greater than or less than the radius of the protrusion 100.

[0073] The first sliding section 21 has a first surface 211 and a second surface 212 which are parallel to each other. The first surface 211 is connected to the locking surface 221 .

[0074] When the liquid box is installed into the installation part of the printer along the +X axis direction, the liquid box is pushed along the +X axis direction, and the protrusion 100 slides from the port 201 into the first sliding section 21. Then, the liquid box is pushed continuously along the +X axis direction. The protrusion 100 of the installation part first slides along the first sliding section 21. During the sliding process of the protrusion 100, the protrusion 100 rotates through the swing rod 200 and drives the tension spring 300 to stretch the tension spring 300. Then, the liquid box is pushed continuously along the +X axis direction, and the protrusion 100 slides into the second sliding section 22. Then, the liquid box is pushed continuously along the +X axis direction, and the protrusion 100 slides into the third sliding section 23 and slides along the third sliding section 23. When the protrusion 100 is in the third sliding section 23, the tension of the tension spring 300 on the swing rod 200 causes the protrusion 100 to press against the side wall of the third sliding section 23 (see Figure 3 As shown in the figure, the installation is completed and the installation process is over. When the installation is completed, the protrusion 100 can move slightly in the third sliding section 23 (i.e., it can move in the range from the third sliding section 23 to the locking surface 221). When the protrusion 100 is at the position where the locking surface 221 is located, the liquid box is still connected to the ink needle 400 and the electrical contact 500 of the installation part. At this time, the liquid box can supply ink to the installation part normally. It should be noted that when the protrusion 100 slides into the third sliding section 23, the tension spring 300 partially rebounds, but is still in an extended state.

[0075] When the liquid box is taken out from the installation part of the printer along the -X axis direction, the liquid box is pulled along the -X axis direction, the protrusion 100 slides from the third sliding section 23 to the second sliding section 22, and the protrusion 100 abuts against the locking surface 221. Then, the liquid box is continued to be pulled along the -X axis direction, and the protrusion 100 rotates to the first surface 211 with the intersection of the locking surface 221 and the first surface 211 as the center. Then, the liquid box is continued to be pulled along the -X axis direction, and the protrusion 100 slides from the first sliding section 21 to the port 201 and slides out from the port 201. The swing rod 200 and the tension spring 300 return to their initial state, the disassembly is completed, and the disassembly process ends.

[0076] It should be noted that the initial state of the swing lever 200 and the tension spring 300 is the state of the swing lever 200 and the tension spring 300 when the liquid cartridge is not installed in the mounting portion of the printer.

[0077] In a possible implementation, Figure 7 and Figure 8 As shown, an elastic member 40 is fixed on the second sliding section 22 , and the surface of the elastic member 40 facing the third sliding section 23 is a locking surface 221 .

[0078] The elastic member 40 may be fixed to the second sliding section 22 by bonding (for example, bonding by glue, sealing resin, etc.). In other embodiments, the elastic member 40 may also be fixed to the second sliding section 22 by welding.

[0079] The elastic member 40 is a component that can be elastically deformed. Exemplarily, the elastic member 40 is a rubber member.

[0080] In the width direction of the liquid box, the length of the elastic member 40 may be equal to the length of the locking surface 221. The length of the locking surface 221 in the width direction of the liquid box may be greater than or equal to the radius of the protrusion 100.

[0081] When the liquid box is installed into the installation part of the printer along the +X axis direction, the liquid box is pushed along the +X axis direction, and the protrusion 100 slides from the port 201 into the first sliding section 21. Then, the liquid box is pushed continuously along the +X axis direction. The protrusion 100 of the installation part first slides along the first sliding section 21. During the sliding process of the protrusion 100, the protrusion 100 rotates through the swing rod 200 and drives the tension spring 300 to stretch the tension spring 300. Then, the liquid box is pushed continuously along the +X axis direction, and the protrusion 100 slides into the second sliding section 22. Then, the liquid box is pushed continuously along the +X axis direction, and the protrusion 100 slides into the third sliding section 23 and slides along the third sliding section 23. When the protrusion 100 is in the third sliding section 23, the tension of the tension spring 300 on the swing rod 200 causes the protrusion 100 to press against the side wall of the third sliding section 23 (see Figure 7 The installation is complete and the installation process is finished.

[0082] When the liquid box is taken out from the installation part of the printer along the -X axis direction, the liquid box is pulled along the -X axis direction, the protrusion 100 slides from the third sliding section 23 toward the second sliding section 22, and the protrusion 100 contacts the locking surface 221. After that, the liquid box is pulled along the -X axis direction, and the protrusion 100 squeezes the elastic member 40, and the elastic member 40 is squeezed by the protrusion 100 to form a guide surface 401 (see Fig. 9 As shown), the guide surface 401 guides the protrusion 100 to slide, so that the protrusion 100 slides into the first sliding section 21, and then continues to pull the liquid box along the -X axis direction, the protrusion 100 slides from the first sliding section 21 to the port 201, and slides out of the port 201, the swing rod 200 and the tension spring 300 return to the initial state, the disassembly is completed, and the disassembly process ends.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
