Description

Technical Field

[0001] The present invention relates to the technical field of printing processing, and in particular to an ink cartridge. Background Art

[0002] Ink cartridges are components used to store printing ink in printers and are an important component of a printer. They can be removably installed in the printer's mounting area, supplying ink to the printer's mounting area, allowing the printer to print normally.

[0003] In the prior art, there is a type of printer mounting assembly comprising a frame and a support member, the support member being rotatably mounted on the frame. The frame is provided with a blocking portion and a liquid inlet. The support member comprises a receiving groove, a mounting cavity, and a through-port connecting the receiving groove and the mounting cavity. A rotatable locking member is disposed within the mounting cavity. The blocking portion locks the supporting member and the locking member by blocking the locking member from rotating along a plane parallel to the plumb line. The ink cartridge comprises an ink reservoir and an adapter mounted on the bottom of the ink reservoir. The bottom of the ink reservoir is provided with a liquid outlet extending through the adapter, which communicates with the ink reservoir cavity. The adapter is provided with an unlocking protrusion. To install the ink cartridge, the ink cartridge is first inserted horizontally into the receiving groove of the support member. The unlocking protrusion on the adapter contacts the locking member on the support member, releasing the locking member from being blocked by the blocking portion, thereby unlocking the supporting member and the locking member. The ink cartridge is then pressed, causing the ink cartridge and the support member to rotate downward, engaging the ink cartridge with the main frame, and connecting the liquid outlet to the liquid inlet, allowing ink to be discharged into the printer. The ink cartridge is then installed.

[0004] However, when the ink cartridge falls, the unlocking protrusion is easily bumped and worn or damaged, thereby affecting the matching accuracy between the unlocking protrusion and the locking part, causing unlocking failure, and then the ink cartridge cannot be installed correctly, causing the printer to stop working.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0047] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0048] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "fixed," and the like should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication between them; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0049] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0050] In the above description, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" and the like mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. 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 different embodiments or examples and features of different embodiments or examples described in this specification without mutual contradiction.

[0051] As described in the background, when an ink cartridge is dropped, the unlocking protrusion is susceptible to collisions, causing wear or damage. This affects the precision of the fit between the unlocking protrusion and the locking member, resulting in unlocking failure and, in turn, causing the printer to malfunction. The inventors have discovered that this problem arises because the unlocking protrusion is exposed outside the ink cartridge housing. When the ink cartridge is dropped, the unlocking protrusion is susceptible to collisions, causing wear or damage. This affects the precision of the fit between the unlocking protrusion and the locking member, causing unlocking failure and, in turn, causing the printer to malfunction.

[0052] To address the aforementioned issues, an embodiment of the present invention provides an ink cartridge comprising a housing and an unlocking mechanism; the unlocking mechanism comprises a transmission portion and a movable portion, the housing having a recessed portion, the movable portion being movably disposed within the recessed portion, and the transmission portion being movably mounted on the housing; the movable portion being in interlocking connection with the transmission portion. When the ink cartridge falls, the movable portion is disposed within the recessed portion of the housing, making it less susceptible to wear or damage from collisions, thereby ensuring the precise fit between the movable portion and the locking member. The movable portion, under the action of the movable portion, allows the locking member to rotate in a direction away from the obstruction of the blocking member, thereby unlocking the locking member and ensuring normal printing of the printer.

[0053] The ink cartridge provided by the embodiment of the present invention is described in detail below with reference to specific embodiments.

[0054] like Figure 1 As shown, this embodiment provides a printer, which may be an inkjet printer. The printer includes a mounting portion 20 and an ink cartridge 10 that is detachably mounted to the mounting portion 20 of the printer. To better illustrate the various components of the mounting portion 20 and the ink cartridge 10, as shown in FIG. Figure 1 and Figure 5 A three-dimensional rectangular coordinate system is established in the , with the Z axis representing the vertical direction, where the +Z axis direction is the plumb bob direction (gravity direction), and the X axis and Y axis representing the direction along the horizontal plane, and the X axis, Y axis and Z axis are orthogonal to each other.

[0055] The mounting portion 20 includes a box-shaped frame 21, a support member 22, a rotation shaft 23, and a liquid inlet 24. The support member 22, the rotation shaft 23, and the liquid inlet 24 are disposed within the frame 21. The frame 21 has an insertion port 201 at the -X-axis end, through which the ink cartridge 10 is inserted.

[0056] The rotation shaft 23 extends in the Y-axis direction, and the support member 22 is provided in the frame 21 at one end in the +X-axis direction so as to be rotatable about the rotation shaft 23 .

[0057] like Figure 2 and Figure 3 As shown, the supporting component 22 has a receiving groove 221 , a mounting cavity 222 and a through portion connecting the receiving groove 221 and the mounting cavity 222 .

[0058] The supporting component 22 includes a bottom plate 2211 and two side ribs 2212 . The bottom plate 2211 and the two side ribs 2212 form a receiving groove 221 . The receiving groove 221 extends in a direction parallel to the bottom plate 2211 .

[0059] like Figure 3 As shown, the supporting component 22 further has a mounting shell 2221 , and a mounting cavity 222 is provided inside the mounting shell 2221 . The mounting cavity 222 extends in a direction perpendicular to the bottom plate 2211 .

[0060] like Figure 2 As shown, the support member 22 has a first region in the plumb direction that overlaps with the projection of the mounting cavity 222, and the through portion includes a first hollow opening 2231 disposed in the first region. Specifically, the first hollow opening 2231 is disposed on the bottom plate 2211 of the support member 22 and communicates with the mounting cavity 222.

[0061] like Figure 2 and Figure 3 As shown, the support component 22 has a second region in the plumb direction that does not overlap with the projection of the mounting cavity 222, and a third region in the X-axis direction. The through-portion further includes a second hollow opening 2232 disposed in the second region and a third hollow opening 2233 disposed in the third region. Specifically, the second hollow opening 2232 is disposed on the bottom plate 2211 of the support component 22; the third hollow opening 2233 is disposed on the mounting shell 2221 of the support component 22. The third hollow opening 2233 communicates with the mounting cavity 222, and the receiving groove 221 can communicate with the mounting cavity 222 through the second and third hollow openings 2232 and 2233.

[0062] like Figure 1 and Figure 5As shown, a rotatable locking member 25 is provided in the mounting cavity 222, and both the supporting member 22 and the locking member 25 can rotate along a plane parallel to the plumb bob direction. Specifically, the supporting member 22 and the locking member 25 can rotate in a plane defined by the X-axis and the Z-axis.

[0063] like Figure 4 As shown, the locking member 25 includes an upper arm 251, a lower arm 252 and an intermediate shaft 253 that are connected to each other. The intermediate shaft 253 extends along the Y-axis direction. The locking member 25 is rotatably arranged in the mounting cavity 222 around the intermediate shaft 253. The upper arm 251 is located above the intermediate shaft 253 in the Z-axis direction, and the lower arm 252 is located below the intermediate shaft 253 in the Z-axis direction.

[0064] The frame 21 has a blocking portion 211 (see FIG. Figure 9 As shown), the blocking portion 211 can be a blocking edge. The lower arm 252 is partially located in the third hollow opening 2233. There is a certain distance between the blocking portion 211 and the locking member 25 in the Z-axis direction. When viewed along the Z-axis direction, the blocking portion 211 and the lower arm 252 of the locking member 25 overlap. It can be understood that the projection of the blocking portion 211 in the Z-axis direction coincides with the projection of the lower arm 252 of the locking member 25. When the ink cartridge 10 is installed in the receiving groove 221 of the support member 22, the locking member 25 is first rotated around the intermediate shaft 253 in the -W direction (see Figure 1 The blocking portion 211 and the lower arm 252 do not overlap in the Z-axis direction, so that the blocking portion 211 does not block the rotation of the locking member 25 and the supporting member 22 as a whole in the +W direction. The blocking portion 211 and the lower arm 252 do not overlap in the Z-axis direction, and the locking member 25 is in the unlocked state. Then, the supporting member 22 and the locking member 25 rotate about the rotation axis 23 in the +W direction. The blocking portion 211 does not block the rotation of the locking member 25 and the assembly consisting of the supporting member 22 and the ink cartridge 10 in the +W direction, allowing the liquid outlet of the ink cartridge 10 to dock with the liquid inlet 24 of the printer mounting portion 20. Both the liquid outlet and the liquid inlet 24 may be pipes.

[0065] It should be noted that if the locking member 25 is not in the unlocked state, when the ink cartridge 10 is installed in the receiving groove 221 of the supporting component 22, and the supporting component 22 and the locking member 25 rotate around the +W direction with the rotating shaft 23 as the center, the blocking portion 211 will block the lower arm 252 of the locking member 25, so that the liquid outlet portion of the ink cartridge 10 and the liquid inlet portion 24 of the installation portion 20 of the printer cannot be docked.

[0066] The installation process of the ink cartridge 10 includes translation operation, unlocking operation and pressing operation. The translation operation is that after the ink cartridge 10 is inserted from the insertion port 201, it moves along the receiving groove 221 of the support component 22 and toward the inner side (+X axis side) of the frame 21. At this time, the movement direction of the ink cartridge 10 is the insertion direction of the installation part 20, that is, the translation direction is the +X axis direction; the unlocking operation is that when the ink cartridge 10 is installed into the support component 22, the locking member 25 rotates around the intermediate shaft 253 around the -W direction, and when viewed along the Z axis, the blocking portion 211 and the lower arm 252 do not overlap, so that the blocking portion 211 will not affect the locking member 25 and the support component 22. The overall rotation along the +W direction constitutes a barrier, and the blocking portion 211 and the lower arm 252 do not overlap in the Z-axis direction. At this time, the locking member 25 is in the unlocked state; the pressing operation is to press the ink cartridge 10, and the support member 22 overcomes the force of the force-applying member 26, and the support member 22 and the locking member 25 rotate around the rotation axis 23 in the +W direction. That is, the support member 22 and the locking member 25 rotate clockwise around the rotation axis 23, so that the liquid outlet of the ink cartridge 10 can dock with the liquid inlet 24 of the installation portion 20 of the printer, and the ink cartridge 10 is installed. It should be noted that Figure 1 The single-dot chain line in FIG. 1 represents a schematic diagram of the ink cartridge 10 after the translation operation; Figure 1 The double-dotted line in FIG represents a schematic diagram of the ink cartridge 10 after the translation operation, the unlocking operation and the pressing operation.

[0067] During the installation process of the ink cartridge 10 , the translation operation and the unlocking operation may be performed simultaneously, or the unlocking operation and the pressing operation may be performed simultaneously.

[0068] The urging member 26 may be a coil spring.

[0069] In some other embodiments, the frame 21 of the mounting portion 20 is further provided with a fixing mechanism for maintaining the installation state of the ink cartridge 10, preventing the ink cartridge 10 and the supporting component 22 from rotating counterclockwise under the action of the force-applying component 26 to return to the state before the pressing operation.

[0070] Example 1

[0071] An embodiment of the present invention provides an ink cartridge 10, which can be removably installed in the installation part 20 of the printer. The installation part 20 includes a frame 21 and a supporting component 22. The supporting component 22 is hinged to the frame 21. The supporting component 22 has a receiving groove 221, an installation cavity 222, and a through portion connecting the receiving groove 221 and the installation cavity 222. The ink cartridge 10 is at least partially located in the receiving groove 221. A rotatable locking member 25 is provided in the installation cavity 222. Both the supporting component 22 and the locking member 25 can rotate along a plane parallel to the plumb bob direction. The locking member 25 includes an upper support arm 251 and a lower support arm 252 connected to each other. The frame 21 has a blocking portion 211 that can prevent the locking member 25 from rotating.

[0072] like Figure 6 and Figure 7 As shown, the ink cartridge 10 includes a housing 11 and an unlocking mechanism; the unlocking mechanism includes a transmission portion 12 and a movable portion 13, and the housing 11 has a recessed portion 111 (see Figure 10 As shown in the figure, the movable part 13 is movably arranged inside the recessed part 111, and the transmission part 12 is movably mounted on the housing 11; the movable part 13 is linked with the transmission part 12, and the transmission part 12 is constructed so that when the ink cartridge 10 is installed into the supporting component 22, it is squeezed by the mounting part 20 and drives the movable part 13 to move, so that the movable part 13 passes through the through-part and abuts against the locking member 25, and the locking member 25 is rotated in the direction of disengaging from the obstruction of the blocking portion 211 under the action of the movable part 13, that is, the locking member 25 is rotated along the -W direction under the action of the movable part 13.

[0073] The length of the ink cartridge 10 is the X-axis, the width of the ink cartridge 10 is the Y-axis, and the height of the ink cartridge 10 is the Z-axis. The X-axis, Y-axis, and Z-axis are perpendicular to each other. The rotation direction within the plane defined by the X-axis and Z-axis is the W-direction.

[0074] The housing 11 includes an ink storage shell 11 a and a connecting shell 11 b . The connecting shell 11 b is mounted on the bottom of the ink storage shell 11 a . The recess 111 is disposed on a side of the connecting shell 11 b away from the ink storage shell 11 a in the height direction of the ink cartridge 10 .

[0075] like Figure 6 and Figure 7 As shown, the recessed portion 111 includes a movable cavity 1111 and a movable opening 1112. The movable portion 13 can slide in the movable cavity 1111. The movable portion 13 can at least partially extend out of the movable opening 1112 under the drive of the transmission portion 12, and the movable portion 13 can pass through the first hollow opening 2231 of the through portion to enter the installation cavity 222 and abut against the lower arm 252 of the locking member 25.

[0076] The ink storage shell 11a is roughly in the shape of a rectangular box. The interior of the ink storage shell 11a is hollow and is used to store ink. An ink storage cavity is provided inside the ink storage shell 11a. A connecting shell 11b for connecting to the mounting portion 20 is detachably provided at the bottom of the ink storage shell 11a.

[0077] A liquid outlet portion 112 is provided at the bottom of the ink storage shell 11a and passes through the connecting shell 11b. The liquid outlet portion 112 is communicated with the ink storage cavity. When the ink cartridge 10 is installed in place in the mounting portion 20, the liquid outlet portion 112 docks with the liquid inlet portion 24 and outputs ink to the printer. The liquid outlet portion is provided close to the -X axis end of the ink storage shell 11a, and the bottom of the connecting shell 11b is opened in the area corresponding to the liquid outlet portion 112 to avoid the liquid outlet portion 112.

[0078] The liquid outlet portion 112 may be an outlet channel on the ink storage housing 11 a for outlet ink; the liquid inlet portion 24 may be an inlet channel on the mounting portion 20 of the printer for introduction of ink.

[0079] The connecting shell 11b is roughly in the shape of a rectangular cover with an upper opening. The connecting shell 11b can be installed on the bottom of the ink storage shell 11a by means of snapping, pasting, welding, etc.

[0080] The shapes of the movable cavity 1111 and the movable opening 1112 are not specifically set, as long as the movable portion 13 can extend out of the movable opening 1112 under the drive of the transmission portion 12 .

[0081] The transmission part 12 is partially exposed at the top of the ink storage housing 11 a , and the transmission part 12 can be pressed by the frame 21 of the mounting part 20 . The transmission part 12 abuts against the movable part 13 .

[0082] The movable portion 13 may abut against the lower arm 252 of the locking member 25 or the upper arm 251 of the locking member 25. In this embodiment, the movable portion 13 abuts against the lower arm 252 of the locking member 25.

[0083] The installation process of the ink cartridge 10: After the ink cartridge 10 is inserted from the insertion port 201, it moves along the receiving groove 221 of the supporting component 22 and toward the inner side (+X axis side) of the frame 21. During the insertion process of the ink cartridge 10, the transmission part 12 is squeezed by the frame 21 of the mounting part 20, and the transmission part 12 drives the movable part 13 to move. The movable part 13 extends out of the movable port 1112, and the movable part 13 passes through the through-portion and abuts against the lower arm 252 of the locking member 25. The locking member 25 rotates in the direction of disengaging from the obstruction of the blocking portion 211 under the action of the movable part 13, that is, the locking member 25 rotates along the -W direction under the action of the movable part 13, that is, the locking member 25 rotates around the intermediate shaft 253 in the -W direction, and makes it rotate along the Z axis direction. It is observed that the blocking portion 211 does not overlap with the lower support arm 252, so the blocking portion 211 will not block the rotation of the whole formed by the locking member 25 and the supporting member 22 along the +W direction. The blocking portion 211 and the lower support arm 252 do not overlap in the Z-axis direction. At this time, the locking member 25 is in an unlocked state; the ink cartridge 10 is pressed, and the supporting member 22 overcomes the force of the force-applying member 26, and the ink cartridge 10, the supporting member 22 and the locking member 25 rotate around the rotating shaft 23 in the +W direction, that is, the ink cartridge 10, the supporting member 22 and the locking member 25 rotate in a clockwise direction around the rotating shaft 23, so that the liquid outlet portion 112 of the ink cartridge 10 docks with the liquid inlet portion 24 of the mounting portion 20 of the printer, and the ink cartridge 10 is installed.

[0084] It should be noted that during the insertion of the ink cartridge 10 , the transmission part 12 may also be squeezed by other components of the mounting part 20 . For example, the transmission part 12 may be squeezed by the supporting component 22 of the mounting part 20 , and the transmission part 12 drives the movable part 13 to move.

[0085] In this embodiment, the translation operation and the unlocking operation are performed simultaneously during the installation process of the ink cartridge 10 .

[0086] The ink cartridge 10 provided in the embodiment of the present invention has the movable portion 13 arranged inside the recessed portion 111 of the shell 11 when the ink cartridge 10 falls. The movable portion 13 is not easily bumped to cause wear or damage, thereby ensuring the matching accuracy between the movable portion 13 and the locking member 25. The locking member 25 can be rotated in the direction of disengaging from the obstruction of the blocking portion 211 under the action of the movable portion 13, and then the locking member 25 can be unlocked, and the ink cartridge 10 can be correctly installed, ensuring that the printer can print normally.

[0087] The matching accuracy between the movable part 13 and the locking member 25 can be understood as the locking member 25 can rotate along the -W direction under the action of the movable part 13, that is, the locking member 25 can rotate along the -W direction under the applied force of the movable part 13.

[0088] In one possible implementation, Figure 9 and Figure 10 As shown, the shell 11 has a movable hole 113, which passes through the top of the ink storage shell 11a. The movable hole 113 is connected to the movable cavity 1111. The transmission part 12 can move along the height direction of the ink cartridge 10 in the movable hole 113. The transmission part 12 abuts against the movable part 13, and the transmission part 12 is partially exposed at the top of the ink storage shell 11a.

[0089] like Figure 8 As shown, the movable part 13 includes a linkage block 131 and an unlocking rod 132. The linkage block 131 abuts against the transmission part 12. The linkage block 131 is fixedly connected to the unlocking rod 132. The linkage block 131 is linked to the transmission part 12. The unlocking rod 132 can pass through the movable port 1112 and slide along the height direction of the ink cartridge 10.

[0090] Among them, such as Figure 10 As shown, the movable hole 113 is at least partially located on the ink storage housing 11a.

[0091] During the installation process of the ink cartridge 10, the portion of the transmission part 12 exposed at the top of the ink storage shell 11a is squeezed by the frame 21 of the installation part 20, and the transmission part 12 moves toward the movable chamber 1111. The transmission part 12 pushes the linkage block 131 of the movable part 13 to slide along the height direction of the ink cartridge 10, and the unlocking rod 132 extends out of the movable opening 1112 under the drive of the linkage block 131. The linkage block 131 allows the unlocking rod 132 to pass through the through part and abut against the lower arm 252 of the locking member 25, and the locking member 25 rotates along the -W direction under the action of the unlocking rod 132.

[0092] It should be noted that the linkage block 131 may be provided to avoid a raised hole structure on the frame 21 (not shown in the figure).

[0093] In one possible embodiment, the ink storage shell 11a is provided with a guide portion, and the transmission portion 12 is connected to the guide portion, and the guide portion is configured to guide the transmission portion 12 to move along the length direction of the ink cartridge 10 and along the height direction of the ink cartridge 10 when the transmission portion 12 is squeezed by the frame 21 of the mounting portion 20.

[0094] Among them, such as Figure 11 As shown, the transmission part 12 includes a first transmission section 121 and a second transmission section 122. The first transmission section 121 and the second transmission section 122 are intersected and connected. The first transmission section 121 is exposed at the top of the ink storage shell 11a, and the second transmission section 122 is in contact with the linkage block 131.

[0095] The first transmission section 121 and the second transmission section 122 can be rod-shaped structures. The first transmission section 12 is located above the second transmission section 122 in the height direction of the ink cartridge 10 , and the second transmission section 122 is located above the linkage block 131 in the height direction of the ink cartridge 10 .

[0096] The extension direction of the first transmission section 121 may not be parallel to the height direction of the ink cartridge 10. In some examples, the first transmission section 121 extends from one end of the second transmission section 122 toward the -X axis side of the ink storage housing 11a.

[0097] It should be noted that the recessed portion 111 and the movable hole 113 may overlap with the liquid outlet portion 112 in the X-axis direction, but since the liquid outlet portion 112 is centered in the Y-axis direction and there is a gap between it and the two side walls of the inner cavity of the ink storage shell 11a, the +X-axis side of the recessed portion 111 and the movable hole 113 needs to be designed into an avoidance shape to avoid the liquid outlet portion 112. Correspondingly, the +X-axis end of the second transmission section 122 and the linkage block 131 also need to be designed to adapt to the shapes of the movable hole 113 and the recessed portion 111 respectively.

[0098] The ink storage shell 11a is provided with guide portions on both sides of the width direction of the ink cartridge 10. Figure 9 、 Figure 10 and Figure 11 As shown, the guide portion includes a plurality of guide grooves 114 spaced apart along the height direction of the ink cartridge 10, and a plurality of positioning shafts 123 are provided on the second transmission section 122. Each positioning shaft 123 extends along the width direction of the ink cartridge 10, and each positioning shaft 123 is slidably disposed in the corresponding guide groove 114. It should be noted that Figure 11 Only a portion of the second transmission section 122 and a portion of the positioning shaft 123 are shown.

[0099] The guide groove 114 extends perpendicularly to the width of the ink cartridge 10 and intersects the length and height of the ink cartridge 10. In some examples, the guide groove 114 has a first end 1141 and a second end 1142 along its extension direction, with the first end 1141 being higher than the second end 1142 in the height direction of the ink cartridge 10. When the first transmission section 121 is pressed by the frame 21 of the mounting portion 20, the positioning shaft 123 slides from the first end 1141 to the second end 1142, causing the unlocking lever 132, driven by the linkage block 131, to extend out of the movable opening 1112 and unlock the locking member 25.

[0100] like Figure 9 As shown, the initial state of the transmission part 12 is the state of the transmission part 12 when the ink cartridge 10 is not installed in the supporting component 22. When the transmission part 12 is in the initial state, the positioning shaft 123 of the transmission part 12 is located at the first end 1141.

[0101] like Figure 12 As shown, when the locking member 25 is in the unlocked state, the positioning shaft 123 of the transmission portion 12 is located at the second end 1142 .

[0102] like Figure 12 As shown, when the ink cartridge 10 is installed in the supporting member 22, the portion of the first transmission section 121 exposed at the top of the ink storage housing 11a is squeezed by the top side (-Z axis side) of the frame 21 of the mounting portion 20, and the first transmission section 121 squeezes the positioning shaft 123 through the second transmission section 122. The positioning shaft 123 slides in the guide groove 114 from the first end 1141 toward the second end 1142, thereby guiding the transmission section 12 to move along the length direction of the ink cartridge 10 and along the height direction of the ink cartridge 10. The second transmission section 122 pushes the linkage block 131 of the movable part 13 to slide along the height direction of the ink cartridge 10, and the unlocking rod 132 is driven by the linkage block 131 to extend out of the movable opening 1112, so that the unlocking rod 132 can pass through the through-portion and abut against the lower arm 252 of the locking member 25, and the locking member 25 is rotated in the direction of disengaging from the obstruction of the blocking portion 211 under the action of the unlocking rod 132, that is, the locking member 25 is rotated along the -W direction under the action of the unlocking rod 132.

[0103] like Figure 10As shown, the active cavity 1111 has an upper wall 111a, a lower wall 111b, and a guide side wall 111c connected to the upper wall 111a and the lower wall 111b. The guide side wall 111c extends along the height direction of the ink cartridge 10, and the linkage block 131 abuts against the guide side wall 111c, and the linkage block 131 can slide along the guide side wall 111c.

[0104] The upper wall 111 a and the lower wall 111 b are both perpendicular to the height direction of the ink cartridge 10 .

[0105] The movable chamber 1111 is square in shape, with the linkage block 131 abutting against the guide sidewalls 111c on either side of the ink cartridge's length and width. This arrangement allows the movable portion 13, driven by the transmission portion 12, to slide along the guide sidewalls 111c along the height of the ink cartridge 10, allowing the unlocking lever to pass through the movable opening 1112 and slide along the height of the ink cartridge 10.

[0106] The unlocking lever extends along the height direction of the ink cartridge 10 , and the shape of the unlocking lever is a square column, and the shape of the movable opening 1112 is a square.

[0107] In one possible implementation, Figure 9 As shown, the unlocking mechanism also includes a reset member 14, which is arranged in the active cavity 1111. The reset member 14 is connected between the linkage block 131 and the inner wall of the active cavity 1111. The reset member 14 is constructed to make the movable part 13 slide toward the inside of the active cavity 1111 when the ink cartridge 10 is removed from the supporting part 22.

[0108] The reset member 14 may be a spring. The movable chamber 1111 has an upper wall 111a and a lower wall 111b in the height direction of the ink cartridge 10. The movable opening 1112 extends through the lower wall 111b. The spring is connected between the linkage block 131 and the lower wall 111b. For example, the spring is welded between the linkage block 131 and the lower wall 111b.

[0109] The installation process of the ink cartridge 10 is as follows: After the ink cartridge 10 is inserted from the insertion port 201, it moves along the receiving groove 221 of the supporting member 22 and toward the inner side (+X axis side) of the frame 21. During the insertion process of the ink cartridge 10, the portion of the transmission portion 12 exposed at the top of the ink storage housing 11a is squeezed by the frame 21 of the mounting portion 20. The first transmission section 121 squeezes the positioning shaft 123 through the second transmission section 122. The positioning shaft 123 slides from the first end 1141 to the second end 1142 in the guide groove 114. The second transmission section 122 pushes the linkage block 131 of the movable portion 13 to slide along the height direction of the ink cartridge 10. The linkage block 131 compresses the spring, and the unlocking rod 132 extends out of the movable opening 1112 under the drive of the linkage block 131. The linkage block 131 can make the unlocking rod 132 pass through the first hollow opening 2231 of the through portion and abut against the lower arm 252 of the locking member 25, and the locking member 25 is in the state of being unlocked. Under the action of the unlocking lever 132, the locking member 25 rotates in the direction of disengaging from the blocking portion 211, that is, the locking member 25 rotates along the -W direction under the action of the unlocking lever 132, that is, the locking member 25 rotates around the intermediate shaft 253 in the -W direction, and when viewed along the Z-axis direction, the blocking portion 211 and the lower support arm 252 do not overlap, so that the blocking portion 211 does not block the rotation of the whole formed by the locking member 25 and the supporting member 22 along the +W direction. The arms 252 do not overlap in the Z-axis direction. At this time, the locking member 25 is in an unlocked state; the pressing operation is to press the ink cartridge 10, and the supporting component 22 overcomes the force of the force-applying component 26. The supporting component 22 and the locking member 25 rotate around the +W direction with the rotating shaft 23 as the center. That is, the supporting component 22 and the locking member 25 rotate clockwise with the rotating shaft 23 as the center, so that the liquid outlet part of the ink cartridge 10 docks with the liquid inlet part 24 of the installation part 20 of the printer, and the ink cartridge 10 is installed.

[0110] When the ink cartridge 10 is removed from the supporting member 22, the spring, under the action of its own elastic force, causes the movable portion 13 to slide toward the inside of the movable cavity 1111. The movable portion 13 presses the second transmission section 122 of the transmission portion 12. The positioning shaft 123 of the transmission portion 12 slides from the second end 1142 toward the first end 1141 in the guide groove 114. The first transmission section 121 moves toward the outside of the ink storage housing 11a, thereby restoring the transmission portion 12 and the movable portion 13 to their initial state. It should be noted that, as Figure 9 As shown, the initial state of the transmission portion 12 is the state of the transmission portion 12 when the ink cartridge is not installed on the installation portion 20 ; the initial state of the movable portion 13 is the state of the movable portion 13 when the ink cartridge is not installed on the installation portion 20 .

[0111] Example 2

[0112] An embodiment of the present invention provides an ink cartridge 10, which can be removably installed in the installation part 20 of the printer. The installation part 20 includes a frame 21 and a supporting component 22. The supporting component 22 is hinged to the frame 21. The supporting component 22 has a receiving groove 221, an installation cavity 222, and a through portion connecting the receiving groove 221 and the installation cavity 222. The ink cartridge 10 is at least partially located in the receiving groove 221. A rotatable locking member 25 is provided in the installation cavity 222. Both the supporting component 22 and the locking member 25 can rotate along a plane parallel to the plumb bob direction. The locking member 25 includes an upper support arm 251 and a lower support arm 252 connected to each other. The frame 21 has a protrusion 212 and a blocking portion 211 that can prevent the locking member 25 from rotating.

[0113] like Figure 13 and Figure 14 As shown, the ink cartridge 10 includes a housing 11 and an unlocking mechanism; the unlocking mechanism includes a transmission portion 12 and a movable portion 13, and the housing 11 has a recessed portion 111 (see Figure 15 As shown in the figure, the movable part 13 is movably arranged inside the recessed part 111, and the transmission part 12 is movably mounted on the housing 11; the movable part 13 is linked with the transmission part 12, and the transmission part 12 is constructed so that when the ink cartridge 10 is installed into the supporting component 22, it is squeezed by the mounting part 20 and drives the movable part 13 to move, so that the movable part 13 passes through the through-part and abuts against the locking member 25, and the locking member 25 is rotated in the direction of disengaging from the obstruction of the blocking portion 211 under the action of the movable part 13, that is, the locking member 25 is rotated along the -W direction under the action of the movable part 13.

[0114] The length of the ink cartridge 10 is the X-axis, the width of the ink cartridge 10 is the Y-axis, and the height of the ink cartridge 10 is the Z-axis. The X-axis, Y-axis, and Z-axis are perpendicular to each other. The rotation direction within the plane defined by the X-axis and Z-axis is the W-direction.

[0115] like Figure 15 As shown, the housing 11 includes an ink storage shell 11a and a connecting shell 11b. The connecting shell 11b is installed at the bottom of the ink storage shell 11a. The recessed portion 111 is provided on a side of the connecting shell 11b away from the ink storage shell 11a in the height direction of the ink cartridge 10.

[0116] The recessed portion 111 includes a movable cavity 1111 and a movable opening 1112. The transmission portion 12 is located on the inner side of the movable cavity 1111. The transmission portion 12 is fixedly connected to the movable portion 13. The transmission portion 12 can rotate in the movable cavity 1111 along a plane parallel to the plumb bob direction. The movable portion 13 can at least partially extend out of the movable opening 1112 under the drive of the transmission portion 12, and the movable portion 13 can pass through the first hollow opening 2231 of the through portion to enter the installation cavity 222 and abut against the upper arm 251 of the locking member 25.

[0117] A liquid outlet portion 112 is provided at the bottom of the ink storage shell 11a and passes through the connecting shell 11b. The liquid outlet portion 112 is communicated with the ink storage cavity. When the ink cartridge 10 is installed in place in the mounting portion 20, the liquid outlet portion 112 docks with the liquid inlet portion 24 and outputs ink to the printer. The liquid outlet portion is provided close to the -X axis end of the ink storage shell 11a, and the bottom of the connecting shell 11b is opened in the area corresponding to the liquid outlet portion 112 to avoid the liquid outlet portion 112.

[0118] The connecting shell 11b is roughly in the shape of a rectangular cover with an upper opening. The connecting shell 11b can be installed on the bottom of the ink storage shell 11a by means of snapping, pasting, welding, etc.

[0119] The shapes of the active cavity 1111 and the active opening 1112 are not specifically set. In some examples, the shape of the active cavity 1111 is square, and the shape of the active opening 1112 is square.

[0120] The movable portion 13 can abut against the upper arm 251 of the locking member 25. The movable portion 13 applies a force to the upper arm 251 of the locking member 25, causing the locking member 25 to rotate in a direction away from the obstruction of the blocking portion 211. That is, the locking member 25 rotates along the -W direction under the action of the movable portion 13.

[0121] The installation process of the ink cartridge 10: After the ink cartridge 10 is inserted from the insertion port 201, it moves along the receiving groove 221 of the supporting component 22 and toward the inner side (+X axis side) of the frame 21; when the ink cartridge 10 is installed in the receiving groove 221 of the supporting component 22, the ink cartridge 10 is pressed, and the supporting component 22 overcomes the force of the force-applying component 26, and the ink cartridge 10, the supporting component 22 and the locking component 25 rotate around the +W direction with the rotating shaft 23 as the center, that is, the ink cartridge 10, the supporting component 22 and the locking component 25 rotate clockwise with the rotating shaft 23 as the center, and the transmission part 12 is squeezed by the protrusion 212 of the frame 21 of the mounting part 20, and drives the movable part 13 to rotate, so that the movable part 13 can pass through the through-hole and abut against the upper arm 251 of the locking component 25, and the locking component 25 rotates in the direction of disengaging from the obstruction of the blocking part 211 under the action of the movable part 13. , that is, the locking member 25 rotates along the -W direction under the action of the unlocking lever 132, that is, the locking member 25 rotates around the intermediate shaft 253 in the -W direction, and when viewed along the Z-axis direction, the blocking portion 211 and the lower arm 252 do not overlap, so that the blocking portion 211 will not block the rotation of the locking member 25 and the supporting member 22 as a whole along the +W direction, and the blocking portion 211 and the lower arm 252 do not overlap in the Z-axis direction. At this time, the locking member 25 is in an unlocked state; continue to press the ink cartridge 10, the supporting member 22 and the locking member 25 continue to rotate around the +W direction around the rotating shaft 23, that is, the supporting member 22 and the locking member 25 continue to rotate clockwise around the rotating shaft 23, so that the liquid outlet portion of the ink cartridge 10 is docked with the liquid inlet portion 24 of the mounting portion 20 of the printer, and the ink cartridge 10 is installed.

[0122] In this embodiment, the unlocking operation and the pressing operation are performed simultaneously during the installation process of the ink cartridge 10 .

[0123] The ink cartridge 10 provided in the embodiment of the present invention has the movable portion 13 arranged inside the recessed portion 111 of the shell 11 when the ink cartridge 10 falls. The movable portion 13 is not easily bumped to cause wear or damage, thereby ensuring the matching accuracy between the movable portion 13 and the locking member 25. The locking member 25 can be rotated in the direction of disengaging from the obstruction of the blocking portion 211 under the action of the movable portion 13, and then the locking member 25 can be unlocked, and the ink cartridge 10 can be correctly installed, ensuring that the printer can print normally.

[0124] The matching accuracy between the transmission part 12 and the locking member 25 can be understood as the locking member 25 can rotate along the -W direction under the action of the transmission part 12, that is, the locking member 25 can rotate along the -W direction under the applied force of the transmission part 12.

[0125] In one possible implementation, Figure 16As shown, the transmission part 12 includes a transmission block 1211 and a transmission rod 1212, the transmission block 1211 is fixedly connected to the transmission rod 1212, the movable part 13 is an unlocking rod, the unlocking rod is fixedly connected to the transmission rod 1212, and the transmission block 1211 can contact the protrusion 212 of the frame 21.

[0126] A rotating shaft 15 is fixed at the connection between the transmission portion 12 and the movable portion 13. The rotating shaft 15 extends along the width direction of the ink cartridge 10 and is rotatably disposed in the movable cavity 1111. This arrangement allows the transmission portion 12 to rotate within the movable cavity 1111 within a plane defined by the X-axis and the Z-axis, with the rotating shaft 15 as the center. In other words, the transmission portion 12 can rotate within a plane perpendicular to the width direction of the ink cartridge, and the movable portion 13 can rotate within the movable cavity 1111 within a plane defined by the X-axis and the Z-axis, with the rotating shaft 15 as the center.

[0127] In this embodiment, the unlocking rod is curved in shape and includes a first section 1331, a second section 1332 and a third section 1333. The second section 1332 is connected between the first section 1331 and the third section 1333. The first section 1331 intersects with the second section 1332, and the second section 1332 intersects with the third section 1333.

[0128] like Figure 1 、 Figure 13 and Figure 14 As shown, after the ink cartridge 10 is installed in the receiving groove 221 of the supporting component 22, the ink cartridge 10 is pressed, the supporting component 22 overcomes the force of the force-applying component 26, and the ink cartridge 10, the supporting component 22 and the locking component 25 rotate around the rotating shaft 23 in the +W direction. That is, the ink cartridge 10, the supporting component 22 and the locking component 25 rotate in the clockwise direction around the rotating shaft 23. The transmission block 1211 of the transmission part 12 is squeezed by the protrusion 212 of the frame 21 of the mounting part 20, and the transmission block 1211 rotates along the +W direction around the center of the rotating shaft 15. The transmission block 1211 drives the unlocking lever to rotate along the +W direction around the center of the rotating shaft 15 through the transmission rod 1212, so that the unlocking lever can be locked in the transmission part 1 2 extends out of the movable opening 1112, the unlocking rod passes through the through-portion and abuts against the upper arm 251 of the locking member 25, and the locking member 25 rotates in the direction of disengaging from the blocking portion 211 under the action of the unlocking rod, that is, the locking member 25 rotates along the -W direction under the action of the unlocking rod, that is, the locking member 25 rotates around the intermediate axis in the -W direction, and when viewed along the Z-axis direction, the blocking portion 211 and the lower arm 252 do not overlap, so that the blocking portion 211 will not constitute a barrier to the rotation of the locking member 25 and the supporting member 22 as a whole along the +W direction, and the blocking portion 211 and the lower arm 252 do not overlap in the Z-axis direction. At this time, the locking member 25 is in an unlocked state.

[0129] In one possible implementation, Figure 17 and Figure 18 As shown, a limiting plate 1113 is provided in the movable cavity 1111, and the limiting plate 1113 extends along the height direction of the ink cartridge 10. When the transmission part 12 and the movable part 13 are in the initial state, that is, when the unlocking mechanism is in the initial state, the unlocking rod abuts against the limiting plate 1113 in the height direction of the ink cartridge 10.

[0130] The limiting plate 1113 can be welded in the movable cavity 1111 .

[0131] like Figure 17 and Figure 18 As shown, the initial state of the transmission portion 12 and the movable portion 13 is the state in which the transmission portion 12 and the movable portion 13 are located when the ink cartridge 10 is not installed on the mounting portion 20. When the transmission portion 12 and the movable portion 13 are in the initial state, the transmission portion 12 and the movable portion 13 are located in a plane perpendicular to the height direction of the ink cartridge 10, that is, in a plane defined by the X-axis and the Y-axis.

[0132] The limiting plate 1113 may be connected to the inner wall of the active cavity 1111 in the width direction of the ink cartridge 10. The side surfaces of the limiting plate 1113 on both sides in the length direction of the ink cartridge 10 are parallel to the plane defined by the Y axis and the Z axis.

[0133] The side surface of the limiting plate 1113 on the +X axis side forms a movable space with the inner wall of the movable cavity 1111 in the length direction of the ink cartridge 10. The transmission block 1211 and the transmission rod 1212 rotate in the movable space, and the unlocking rod can rotate below the limiting plate 1113, that is, the unlocking rod can move in the space below the bottom of the limiting plate 1113.

[0134] The mass of the transmission part 12 is greater than the mass of the movable part 13, that is, the sum of the mass of the transmission block 1211 and the mass of the transmission rod 1212 is greater than the mass of the unlocking lever. With this arrangement, when the ink cartridge 10 is removed from the support member 22, the transmission part 12 rotates in the -W direction around the rotation shaft 15 under the action of gravity, and the transmission part 12 drives the unlocking lever to rotate in the -W direction around the rotation shaft 15 until the unlocking lever abuts against the limit plate 1113 in the height direction of the ink cartridge 10. At this time, the transmission part 12 and the unlocking lever are in the initial state (see Figure 17 and Figure 18 shown).

[0135] It should be noted that if Figure 1 、 Figure 13 and Figure 14As shown, after the ink cartridge 10 is installed in the receiving groove 221 of the supporting component 22, the ink cartridge 10 is pressed, and the transmission block 1211 of the transmission part 12 is squeezed by the protrusion 212 of the frame 21 of the installation part 20. The transmission block 1211 rotates along the -W direction with the rotating shaft 15 as the center. The transmission block 1211 drives the unlocking lever to rotate along the -W direction with the rotating shaft 15 as the center through the transmission rod 1212, so that the unlocking lever can extend out of the movable opening 1112 under the drive of the transmission part 12, and the unlocking lever passes through the through portion and abuts against the upper arm 251 of the locking member 25, and the locking member 25 is disengaged from the blocking portion 211 under the action of the unlocking lever. That is, the locking member 25 rotates in the -W direction under the action of the unlocking lever, that is, the locking member 25 rotates around the intermediate axis in the -W direction, and when viewed along the Z-axis direction, the blocking portion 211 and the lower arm 252 do not overlap, so that the blocking portion 211 will not block the rotation of the locking member 25 and the supporting member 22 as a whole along the +W direction, and the blocking portion 211 and the lower arm 252 do not overlap in the Z-axis direction. At this time, the locking member 25 is in an unlocked state, and the transmission block 1211 and the transmission rod 1212 are higher than the height of the unlocking lever in the height direction of the ink cartridge 10.

[0136] Example 3

[0137] Another ink cartridge 10 is provided in this embodiment. The difference between this embodiment and embodiment 2 is that: in this embodiment, the mass of the transmission part 12 is equal to the mass of the movable part 13, and a torsion spring is provided on the rotating shaft 15. The torsion spring can restore the transmission part 12 and the unlocking rod to their initial state when the ink cartridge 10 is removed from the supporting part 22.
