[0040] The ink cartridge provided by the embodiment of the utility model is described in detail below in conjunction with specific embodiments.

[0041] 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 can be detachably mounted to the mounting portion 20 of the printer. To better illustrate 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 , 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.

[0042] The mounting portion 20 includes a box-shaped frame 21, a support member 22, a rotation shaft 23, and a liquid introduction portion 24. The support member 22, the rotation shaft 23, and the liquid introduction portion 24 are arranged in the frame 21. The frame 21 is provided with an insertion port 201 at the -X axis end, and the ink cartridge 10 is inserted into the frame 21 through the insertion port 201.

[0043] 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 around the rotation shaft 23 .

[0044] 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 .

[0045] The supporting component 22 has 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 .

[0046] 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 .

[0047] like Figure 2 As shown, the support component 22 has a first area in the plumb direction that coincides with the projection of the installation cavity 222, and the through portion includes a first hollow opening 2231 disposed on the first area. Specifically, the first hollow opening 2231 is disposed on the bottom plate 2211 of the support component 22, and the first hollow opening 2231 is connected to the installation cavity 222.

[0048] like Figure 2 and Figure 3 As shown, the support component 22 has a second area in the plumb direction that does not overlap with the projection of the installation cavity 222, the support component 22 has a third area in the X-axis direction, and the through portion further includes a second hollow opening 2232 disposed on the second area and a third hollow opening 2233 disposed on the third area. 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 installation shell 2221 of the support component 22, the third hollow opening 2233 is communicated with the installation cavity 222, and the receiving groove 221 can be communicated with the installation cavity 222 through the second hollow opening 2232 and the third hollow opening 2233.

[0049] 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 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.

[0050] 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.

[0051] like Figure 6 As shown, the frame 21 has a blocking portion 211 that can block the locking member 25 from rotating, and the blocking portion 211 can be a blocking edge. The lower arm 252 is partially located in the third hollow opening 2233, and 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, which can be understood as 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 supporting 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 are rotated so that when viewed along the Z-axis direction, the blocking portion 211 does not overlap with the lower arm 252, so that the blocking portion 211 does not block the rotation of the locking member 25 and the supporting member 22 as a whole along 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 an unlocked state. Then the supporting member 22 and the locking member 25 rotate around 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 along the +W direction, so that the liquid outlet of the ink cartridge 10 can be docked with the liquid inlet 24 of the printer's mounting portion 20. Both the liquid outlet and the liquid inlet 24 can be pipes.

[0052] It should be noted that if the locking member 25 is not in the unlocked state, when the ink cartridge 10 is installed into 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.

[0053] 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 supporting component 22 and toward the inner side (+X axis side) of the frame 21. At this time, the moving 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 supporting 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 does not overlap with the lower arm 252, so that the blocking portion 211 will not affect the locking member 25 and the supporting component 22. The overall rotation along the +W direction constitutes a blockage, and the blocking part 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; the pressing operation is to press the ink cartridge 10, and the supporting member 22 overcomes the force of the force-applying member 26, and the supporting member 22 and the locking member 25 rotate around the +W direction with the rotating shaft 23 as the center, that is, the supporting member 22 and the locking member 25 rotate clockwise with the rotating shaft 23 as the center, so that the liquid outlet of the ink cartridge 10 can dock with the liquid inlet 24 of the installation part 20 of the printer, and the ink cartridge 10 is installed. It should be noted that Figure 1 The single-dot chain line in represents the schematic diagram of the ink cartridge 10 after the translation operation; Figure 1 The double-dotted line in represents the schematic diagram of the ink cartridge 10 after the translation operation, the unlocking operation and the pressing operation.

[0054] The unlocking operation and the pressing operation of the ink cartridge 10 may be performed simultaneously.

[0055] The urging member 26 may be a coil spring.

[0056] 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 to prevent the ink cartridge 10 and the supporting member 22 from rotating counterclockwise under the action of the force-applying member 26 to return to the state before the pressing operation.

[0057] An embodiment of the utility model provides an ink cartridge 10, which can be detachably installed in a mounting portion 20 of a printer. The mounting portion 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, a mounting cavity 222, and a through portion connecting the receiving groove 221 and the mounting 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 mounting 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 block the locking member 25 from rotating.

[0058] like Figure 7 and Figure 8 As shown, the ink cartridge 10 includes a housing 11 and an unlocking mechanism; the unlocking mechanism includes a rotating member 12 , the housing 11 has a recessed portion 111 , and the rotating member 12 is rotatably disposed inside the recessed portion 111 .

[0059] The rotating member 12 includes a transmission part 121 and an unlocking part 122, the transmission part 121 is fixedly connected to the unlocking part 122, and the transmission part 121 is configured so that when the ink cartridge 10 is installed in the supporting member 22 and the supporting member 22 and the locking member 25 rotate toward the blocking member 211, the protrusion 212 (see Figure 6 As shown in the figure, the unlocking portion 122 is squeezed and driven to rotate, so that the unlocking portion 122 passes through the through portion and abuts against the upper arm 251 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 portion 122, that is, the locking member 25 is rotated along the -W direction under the action of the unlocking portion 122.

[0060] The length direction of the ink cartridge 10 is the X-axis direction, the width direction of the ink cartridge 10 is the Y-axis direction, the height direction of the ink cartridge 10 is the Z-axis direction, the X-axis, the Y-axis and the Z-axis are perpendicular to each other, and the rotation direction in the plane where the X-axis and the Z-axis are located is the W direction.

[0061] The housing 11 includes an ink storage shell 11 a and a connecting shell 11 b . The connecting shell 11 b is installed at the bottom of the ink storage shell 11 a . The recess 111 is arranged 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 .

[0062] like Fig. 9 and Fig.10 As shown, the recessed portion 111 includes an active cavity 1111 and an active opening 1112, the transmission portion 121 and the unlocking portion 122 are located on the inner side of the active cavity 1111, the transmission portion 121 can rotate along a plane parallel to the plumb direction in the active cavity 1111, the unlocking portion 122 can extend out of the active opening 1112 driven by the transmission portion 121, and the unlocking portion 122 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.

[0063] 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 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.

[0064] 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 connected to 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 112 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.

[0065] The connecting shell 11b is roughly in the shape of a rectangular cover with an opening at the top. The connecting shell 11b can be installed on the bottom of the ink storage shell 11a by means of snapping, pasting, welding, etc.

[0066] The shapes of the movable cavity 1111 and the movable opening 1112 are not specifically set, as long as the unlocking portion 122 can extend out of the movable opening 1112 driven by the transmission portion 121 .

[0067] 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 one end of 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 member 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 member 25 rotate clockwise with the rotating shaft 23 as the center, and the transmission part 121 of the rotating member 12 is squeezed by the protrusion 212 of the frame 21 of the mounting part 20, and drives the unlocking part 122 to rotate, so that the unlocking part 122 can pass through the through-portion and abut against the upper arm 251 of the locking member 25, and the locking member 25 rotates in the direction of breaking away from the obstruction of the blocking part 211 under the action of the unlocking part 122. That is, the locking member 25 rotates along the -W direction under the action of the unlocking portion 122, that is, the locking member 25 rotates around the -W direction with the intermediate shaft 253 as the center, 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 ink cartridge 10, the supporting member 22 and the locking member 25 continue to rotate around the +W direction with the rotating shaft 23 as the center, that is, the ink cartridge 10, the supporting member 22 and the locking member 25 continue to rotate clockwise with the rotating shaft 23 as the center, so that the liquid outlet of the ink cartridge 10 is docked with the liquid inlet 24 of the installation portion 20 of the printer, and the ink cartridge 10 is installed.

[0068] The ink cartridge 10 provided in the embodiment of the utility model, when the ink cartridge 10 falls, the rotating member 12 is arranged inside the recessed portion 111 of the shell 11, and the rotating member 12 is not easily worn or damaged by bumps, thereby ensuring the matching accuracy between the rotating member 12 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 unlocking portion 122 of the rotating member 12, and then the locking member 25 can be unlocked, the ink cartridge 10 can be correctly installed, and the printer can print normally.

[0069] The matching accuracy between the rotating member 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 unlocking portion 122 of the rotating member 12, that is, the locking member 25 can rotate along the -W direction under the applied force of the unlocking portion 122 of the rotating member 12.

[0070] In a possible implementation, Figure 8 As shown, the rotating member 12 further includes a rotating shaft 123, which is fixed at the connection between the transmission part 121 and the unlocking part 122, and extends along the width direction of the ink cartridge 10. The rotating shaft 123 is rotatably arranged in the active cavity 1111. In this way, the rotating member 12 can rotate in the plane defined by the X-axis and the Z-axis in the active cavity 1111, that is, the rotating member 12 can rotate in the plane perpendicular to the width direction of the ink cartridge.

[0071] The transmission part 121 may include a transmission block 1211 and a transmission rod 1212, and the transmission block 1211 is fixedly connected to the transmission rod 1212. The shapes of the transmission block 1211 and the transmission rod 1212 are not specifically set.

[0072] The unlocking portion 122 may be an unlocking rod, which is fixedly connected to the transmission rod 1212, and the transmission block 1211 may contact the protrusion 212 of the frame 21. The shape of the unlocking rod needs to ensure that the unlocking rod abuts against the upper arm 251 of the locking member 25 after rotation, and the upper arm 251 of the locking member 25 may receive the force of the unlocking rod and rotate along the -W direction. In this embodiment, the shape of the unlocking rod is curved, and the unlocking rod includes a first section 1221, a second section 1222, and a third section 1223, the second section 1222 is connected between the first section 1221 and the third section 1223, the first section 1221 is intersected with the second section 1222, and the second section 1222 is intersected with the third section 1223.

[0073] Figure 5 This is a schematic diagram showing that the ink cartridge 10 is installed into the supporting member 22 without pressing the ink cartridge 10 . Figure 6 It is a schematic diagram when the ink cartridge 10 is installed into the supporting component 22, and the ink cartridge 10 is pressed, and the locking member 25 is in the unlocked state.

[0074] like Figure 1 and Figure 6 As shown, after the ink cartridge 10 is installed into 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 +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 in the clockwise direction with the rotating shaft 23 as the center, and the transmission block 1211 of the rotating component 12 is squeezed by the protrusion 212 of the frame 21 of the mounting portion 20, and the transmission block 1211 rotates along the +W direction with the rotating shaft 123 as the center. The transmission block 1211 drives the unlocking lever to rotate along the +W direction with the rotating shaft 123 as the center through the transmission rod 1212, so that the unlocking lever can be locked in the transmission portion 12 1 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 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 hinder 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.

[0075] In a possible implementation, Fig. 9 and Fig.10 As shown, a limiting plate 1113 is provided in the active cavity 1111, and the limiting plate 1113 extends along the height direction of the ink cartridge 10. When the rotating member 12 is in the initial state, the unlocking rod abuts against the limiting plate 1113 in the height direction of the ink cartridge 10. Specifically, the second section 1222 of the unlocking rod abuts against the limiting plate 1113 in the height direction of the ink cartridge 10.

[0076] Among them, the limiting plate 1113 can be fixedly arranged in the active cavity 1111.

[0077] like Fig. 9 and Fig.10 As shown, the initial state of the rotating member 12 is the state of the rotating member 12 when the ink cartridge is not installed on the mounting portion 20. When the rotating member 12 is in the initial state, the rotating member 12 is 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.

[0078] The limiting plate 1113 may be connected to the inner wall of the active chamber 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.

[0079] The side surface of the limit plate 1113 on the +X axis direction forms a movable space with the inner wall of the movable chamber 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 limit plate 1113, that is, the unlocking rod can move in the space below the bottom of the limit plate 1113.

[0080] The mass of the transmission part 121 is greater than the mass of the unlocking part 122, 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 part 122. In this configuration, when the ink cartridge 10 is removed from the supporting component 22, the rotating member 12 rotates along the -W direction with the rotating shaft 123 as the center under the gravity of the transmission part 121 until the unlocking rod abuts against the limiting plate 1113 in the height direction of the ink cartridge 10, and at this time, the rotating member 12 is in the initial state.

[0081] It should be noted that if Figure 1 and Figure 6 As shown, after the ink cartridge 10 is installed into the receiving groove 221 of the supporting component 22, the ink cartridge 10 is pressed, and the transmission block 1211 of the rotating member 12 is squeezed by the protrusion 212 of the frame 21 of the mounting portion 20, and the transmission block 1211 rotates along the -W direction with the center of the rotating shaft 123. The transmission block 1211 drives the unlocking lever to rotate along the -W direction with the center of the rotating shaft 123 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 121, 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 moved toward the disengagement portion 211 under the action of the unlocking lever. The locking member 25 rotates in the direction of blocking, 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 -W direction with the intermediate shaft 253 as the center, 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 rod in the height direction of the ink cartridge 10. It should also be pointed out that in other embodiments, the unlocking mechanism can also be provided by providing a torsion spring, which is provided on the rotating shaft 123, and the torsion spring can restore the rotating member 12 to the initial state when the ink cartridge 10 is removed from the supporting member 22.
