[0037] The adapter, the ink cartridge assembly and the ink cartridge provided by the utility model embodiment will be described in detail below in combination with specific embodiments.

[0038] Embodiment one

[0039] Referring to Figure 1 and Figure 2 , the printing device includes a mounting part 10, the mounting part 10 has an installation cavity 11, one end of the mounting part 10 is an installation port 111 communicating with the installation cavity 11, and the other end of the mounting part 10 is a front sealing plate 101 of the mounting part 10.

[0040] The installation cavity 11 is provided with an ink needle 12, the ink needle 12 is fixedly arranged relative to the front sealing plate 101 of the mounting part 10, and the ink needle 12 extends in the X-axis direction.

[0041] In a possible implementation manner, the number of installation cavities 11 in the mounting part 10 can be 1, of course, the number of installation cavities 11 in the mounting part 10 can also be 4, and the four installation cavities 11 are respectively used to install the ink cartridges storing four different color inks, and the four different colors are respectively red, yellow, cyan and black, realizing color printing.

[0042] The front sealing plate 101 of the mounting part 10 has a through hole for the ink supply needle 12 to pass through, the ink supply needle 12 extends into the mounting cavity 11 through the through hole, the ink supply needle 12 has a hollow structure, the inside of the ink supply needle 12 has a channel for ink to pass through, and one end of the ink supply needle 12 extending into the mounting cavity 11 is an ink inlet end 121 (see Figure 3 The ink inlet end 121 is used for docking with the ink cartridge to form a channel for fluid flow at the connection position of the ink cartridge and the ink supply needle 12.

[0043] A blocking part is arranged in the mounting cavity 11, and the blocking part is movable relative to the mounting cavity 11. Part of the blocking part is located in a containing space 122 around the ink supply needle 12 to limit the cooperation of the ink supply needle 12 and the ink cartridge. Further, in the X-axis direction, the blocking part has a part located at the same position as the ink inlet end 121 to limit the cooperation of the ink supply needle 12 and the ink cartridge. Further, part of the blocking part is located on one side of the ink inlet end 121 of the ink supply needle 12 in the +X-axis direction to limit the cooperation of the ink supply needle 12 and the ink cartridge.

[0044] It should be noted that the containing space 122 is used to contain the ink outlet part of the ink cartridge. That is, when the ink cartridge is mounted to the mounting cavity 11, part of the containing space 122 is a space region in which the ink outlet part of the ink cartridge is located.

[0045] The ink outlet part of the ink cartridge is a part of the structure of the ink cartridge for supplying ink to flow out. In some examples, the ink outlet part can be an ink outlet pipeline. The shape of the ink outlet pipeline can be cylindrical or other shapes.

[0046] Referring to Figure 1 and Figure 2 In order to better illustrate the ink cartridge provided in the present application, a coordinate system is established: the length direction of the ink cartridge is the X-axis direction, the width direction of the ink cartridge is the Y-axis direction, and the height direction of the ink cartridge is the Z-axis direction, wherein the X-axis, the Y-axis and the Z-axis are perpendicular to each other, or the X-axis, the Y-axis and the Z-axis are close to perpendicular to each other. The mounting direction of the ink cartridge is along the length direction of the ink cartridge.

[0047] The utility model embodiment provides a kind of ink cartridge assembly. Ink cartridge assembly includes ink cartridge, and ink cartridge is detachably mounted to the mounting cavity 11 of printing equipment.

[0048] The side of the ink cartridge in the-X-axis direction is the front of the ink cartridge, and the side of the ink cartridge in the+X-axis direction is the rear of the ink cartridge. The side of the ink cartridge in the-Z-axis direction is the lower side of the ink cartridge, and the side of the ink cartridge in the+Z-axis direction is the upper side of the ink cartridge.

[0049] Referring to Figures 1 to 3As shown, the ink cartridge includes a cartridge body 20, which has an accommodation cavity 21 inside for accommodating ink. The surface of the cartridge body 20 on one side in the -X axis direction is a front surface 201, and the surface of the cartridge body 20 on one side in the +X axis direction is a rear surface 202. The surface of the cartridge body 20 on one side in the -Z axis direction is a lower surface 203, and the surface of the cartridge body 20 on one side in the +Z axis direction is an upper surface 204.

[0050] The front surface 201 is provided with an ink outlet 22 that communicates with the accommodation cavity 21. The ink outlet 22 is used to be docked with the ink inlet end 121 of the ink supply needle 12.

[0051] In some examples, the ink cartridge has an ink outlet channel, and the ink outlet 22 is one end of the ink outlet channel. The ink outlet channel is cylindrical, and can protrude outward from the front surface 201. When the ink cartridge is installed into the installation cavity 11 of the installation portion 10, a part of the space occupied by the ink outlet channel can be a part of the accommodation space 122.

[0052] In the present embodiment, referring to Figure 3 As shown, the accommodation space 122 around the ink supply needle 12 can at least be a cylindrical region with the ink supply needle 12 as the central axis and with the distance from the center of the ink outlet 22 of the ink cartridge to the lower surface 203 of the ink cartridge as the radius.

[0053] In some examples, the cartridge body 20 includes a cartridge main body 20a and a cover member 20b, which is movably arranged on the front surface 201 in the height direction of the ink cartridge and is located between the ink outlet 22 and the upper surface 204.

[0054] The front surface 201 is provided with an action portion 23. The action portion 23 is located inside the cover member 20b and extends in the Z axis direction. In some examples, the action portion 23 can be a protrusion. The protrusion extends in the Z axis direction and has a thickness in the Y axis direction. In other embodiments, the cartridge body 20 can also not be provided with the cover member 20b, and the action portion 23 can be directly provided on the front surface 201 of the cartridge body 20.

[0055] The action portion 23 has an inclined surface. The inclined surface is used to abut against a blocking member of a printing device. During the process of installing the ink cartridge into the installation cavity 11, the inclined surface of the action portion 23 abuts against the blocking member to move a part of the blocking member away from the ink cartridge and make the ink outlet 22 contact the ink supply needle 12.

[0056] The ink cartridge assembly includes an adapter 30 configured to be installed in the installation cavity 11 to limit the blocking member to return to the initial position. In this way, the blocking member is in an unlocked state, thereby avoiding the ink cartridge acting on the blocking member to unlock the blocking member 13 each time, and thus the service life of the ink cartridge can be improved.

[0057] In some examples, the ink cartridge further comprises a chip, which can be arranged on the upper surface 204 or the front surface 201; the chip can be arranged on the cartridge body 20a or the cover component 20b.

[0058] It should be noted that the initial position of the blocking component is the position of the blocking component when the ink cartridge and the adapter 30 are not installed in the installation cavity 11. When the blocking component is not in the initial position, the blocking component no longer restricts the cooperation of the ink supply needle 12 and the ink cartridge, the ink supply needle 12 can be in contact with the ink outlet 22, and the blocking component is in the unlocked state.

[0059] In a possible implementation, the blocking component comprises a blocking piece 13 and a moving piece 14, the blocking piece 13 is movably arranged in a first direction, and the moving piece 14 is movably arranged in a second direction, the blocking piece 13 is used to restrict the cooperation of the ink supply needle 12 and the ink cartridge, and the moving piece 14 is used to restrict the movement of the blocking piece 13.

[0060] In the present embodiment, the X-axis direction can be an example of the first direction, that is, in the present embodiment, the blocking piece 13 can move in the X-axis direction.

[0061] In the present embodiment, the blocking piece 13 comprises a bottom plate 131 and a vertical plate 132, the bottom plate 131 is slidably arranged on the inner bottom wall surface of the installation cavity 11 in the first direction, the bottom of the vertical plate 132 is fixedly connected to the bottom plate 131, and the vertical plate 132 is internally provided with a relief hole 1321, the ink supply needle 12 can pass through the relief hole 1321 when the blocking piece 13 slides in the first direction.

[0062] The inner bottom wall of the installation cavity 11 is provided with a baffle portion 16, and an elastic piece 15 is arranged between the baffle portion 16 and the blocking piece 13, one end of the elastic piece 15 is fixedly connected to the baffle portion 16, the other end of the elastic piece 15 is fixedly connected to the blocking piece 13, and the elastic piece 15 is used to drive the blocking piece 13 to move close to the baffle portion 16, so that when the ink cartridge is not installed in the installation cavity 11 of the printing device (see Figure 1 illustrated), the vertical plate 132 of the blocking piece 13 is farther away from the front baffle plate 101 relative to the ink inlet end 121, and the cooperation of the ink supply needle 12 and the ink cartridge is restricted. The elastic piece 15 can be a spring, for example.

[0063] The second direction can be at any angle with the Z-axis direction. The moving piece 14 has an opening cavity 142 facing the ink cartridge, and the moving piece 14 is used to restrict the movement of the blocking piece 13 when the moving piece 14 abuts against the blocking piece 13, so that the blocking piece 13 restricts the cooperation of the ink supply needle 12 and the ink cartridge, and the moving piece 14 is used to stop restricting the movement of the blocking piece 13 when the moving piece 14 is disengaged from the abutment against the blocking piece 13, so that the blocking piece 13 releases the restriction of the cooperation of the ink supply needle 12 and the ink cartridge.

[0064] In some examples, the second direction is parallel to the direction of the Z axis, that is, the blocking piece 13 is movable along the direction of the Z axis. When the moving piece 14 moves in the second direction (+Z axis direction), the moving piece 14 no longer limits the movement of the blocking piece 13 in the first direction, so that the blocking piece 13 can slide along the first direction on the inner bottom wall surface of the mounting cavity 11.

[0065] The moving piece 14 includes a moving body 141 and a leg 143 connected to the bottom end of the moving body 141, and an opening cavity 142 can be formed in the moving body 141. The leg 143 extends in the second direction and is used to abut against one end of the blocking piece 13 away from the mounting port 111. In this example, the leg 143 is used to abut against the bottom plate 131 of the blocking piece 13 in the first direction, thereby limiting the movement of the blocking piece 13 in the first direction as a whole, so that the ink inlet end 121 of the ink supply needle 12 is not exposed outside the vertical plate 132, and the blocking piece 13 limits the docking of the ink supply needle 12 with the ink outlet 22.

[0066] One end of the moving piece 14 facing the cartridge 20 has a guide protrusion 144. During the installation of the ink cartridge into the mounting cavity 11, the guide protrusion 144 abuts against the acting part 23. Through the mutual extrusion action of the acting part 23 and the guide protrusion 144, the moving piece 14 is pushed to move in the second direction.

[0067] In some examples, referring to Figure 1 When the ink cartridge is not installed into the mounting cavity 11 of the printer, the leg 143 of the moving piece 14 abuts against one end of the blocking piece 13 away from the mounting port 111 in the first direction. Under the abutting action of the moving piece 14 on the blocking piece 13, the blocking piece 13 is locked in a position limiting the cooperation of the ink supply needle 12 with the ink cartridge. The blocking piece 13 cannot move away from the mounting port 111 in the first direction to expose the ink inlet end 121 and the accommodation space 122 of the ink supply needle 12, thereby realizing the cooperation of the blocking piece 13 with the ink cartridge.

[0068] Further, in the first direction, the adapter 30 abuts against the blocking piece 13 and the baffle part 16 of the mounting cavity 11, respectively, to limit the blocking piece 13 to return to the initial position. It should be noted that the initial position of the blocking piece 13 is the position of the blocking piece 13 when the ink cartridge and the adapter 30 are not installed in the mounting cavity 11.

[0069] In some examples, the adapter 30 can be detachably arranged on the cartridge body 20 of the ink cartridge. The adapter 30 is configured to be separated from the cartridge body 20 during the installation of the ink cartridge into the mounting cavity 11 and arranged in the mounting cavity 11 to limit the blocking piece 13 to return to the initial position.

[0070] Specifically, referring to Figure 1As shown, during the process of installing the ink cartridge assembly from the mounting port 111 into the mounting cavity 11 of the printing device along the first direction, when the actuating part 23 abuts against the moving part 14, the moving part 14 moves upward along the second direction, and the blocking part 13 unlocks from the position restricting the ink supply needle 12 from engaging with the ink cartridge. At the same time, the ink cartridge abuts against the blocking part 13 and pushes the blocking part 13 to move inward toward the mounting cavity 11 along the first direction. The elastic member 15 extends, and the blocking part 13 leaves the position of the ink inlet end 121 of the ink supply needle 12. The receiving space 122 around the ink supply needle 12 is exposed, thereby unlocking the blocking part 13 and enabling the engagement of the ink supply needle 12 with the ink cartridge. Simultaneously, the adapter 30 separates from the cartridge body 20. See also Figure 2 and Figure 3 As shown, when the ink cartridge is installed into the mounting cavity 11 of the printing device, the adapter 30 is located between the baffle portion 16 and the blocking member 13 of the mounting cavity 11.

[0071] See Figure 4 As shown, during the removal of the ink cartridge from the mounting cavity 11 in the first direction, the adapter 30 remains inside the mounting cavity 11. The adapter 30 abuts against the baffle 16 and the blocking member 13 of the mounting cavity 11, respectively. When the cartridge body 20 is removed from the mounting cavity 11, the adapter 30 can prevent the blocking member 13 from returning to its initial position. At this time, the leg 143 of the moving member 14 abuts against the base plate 131 of the blocking member 13 in the second direction, so that the moving member 14 no longer restricts the movement of the blocking member 13 in the first direction, and the blocking member is in an unlocked state. Thus, when the ink cartridge is reinstalled, the actuating part 23 of the ink cartridge does not need to interact with the moving member 14 to unlock the blocking member 13, thereby avoiding the need for the ink cartridge to interact with the moving member 14 to unlock the blocking member 13 each time, and thus improving the lifespan of the ink cartridge.

[0072] In some examples, the number of mounting cavities 11 within the mounting section 10 is not just one, but can be four. The four mounting cavities 11 are used to install and store four ink cartridges, each ink cartridge having an adapter 30. Each adapter 30 corresponds to a stop member 13, and multiple adapters 30 are connected sequentially along a third direction.

[0073] In other embodiments, the adapter may be provided with an action part, in which case the action part only interacts with the blocking component when the adapter is first installed.

[0074] The third direction can be the Z-axis direction.

[0075] In one possible implementation, see Figure 3As shown, the lower surface 203 of the cartridge body 20 is provided with a recess structure 205, and the adapter 30 is at least partially movably arranged in the recess structure 205. In this way, by first arranging the adapter 30 in the recess structure 205, the cartridge body 20 can drive the adapter 30 to move during the process of mounting the ink cartridge into the mounting cavity 11 of the printer.

[0076] In some examples, the recess structure 205 of the lower surface 203 of the cartridge body 20 can be a groove. The adapter 30 is partially arranged in the groove, and the adapter 30 can be separated from the groove under the action of gravity. During the process of mounting the ink cartridge into the mounting cavity 11 of the printer, the adapter 30 can fall between the blocking piece 13 and the baffle part 16 by gravity.

[0077] In some examples, the adapter 30 and the cartridge body 20 can be connected by an adhesive material. Under the action of the adhesive material, the cartridge body 20 of the ink cartridge drives the adapter 30 to move and mount into the mounting part. When the ink cartridge is removed, the movement of the adapter 30 in the +X direction is limited by the baffle part 16, and the adapter 30 remains in the mounting part.

[0078] In a possible implementation, in the first direction, the size of the adapter 30 is greater than the distance between the blocking piece 13 in the initial position and the baffle part 16 of the mounting cavity 11. In this way, when the adapter 30 respectively abuts against the baffle part 16 of the mounting cavity 11 and the blocking piece 13, the blocking piece 13 can be limited to return to the initial position.

[0079] In some examples, in the first direction, the size of the adapter 30 is equal to the distance between the blocking piece 13 and the baffle part 16 of the mounting cavity 11 when the ink cartridge is mounted into the mounting cavity 11 of the printing device. In this way, during the process of removing the ink cartridge from the mounting cavity 11 of the printing device, the adapter 30 can limit the movement of the blocking piece 13 in the first direction, i.e., the blocking piece 13 does not move closer to the baffle part 16 under the pulling of the elastic piece 15, so that the blocking part is in the unlocked state.

[0080] It should be noted that, in the first direction, the size of the adapter 30 can also be less than the distance between the blocking piece 13 and the baffle part 16 of the mounting cavity 11 when the ink cartridge is mounted into the mounting cavity 11 of the printing device, and greater than the distance between the blocking piece 13 in the initial position and the baffle part 16 of the mounting cavity 11. In this way, during the process of removing the ink cartridge from the mounting cavity 11 of the printing device, the blocking piece 13 abuts against the adapter 30 after moving a certain distance under the pulling of the elastic piece 15. At this time, the leg part 143 of the moving piece 14 abuts against the bottom plate 131 of the blocking piece 13 in the second direction, so that the moving piece 14 does not limit the movement of the blocking piece 13 in the first direction, and the blocking part is in the unlocked state.

[0081] In a possible implementation, referring toFigure 3 As shown, the adapter 30 is provided with a relief structure 31 for avoiding the interference between the elastic member 15 and the blocking member 13.

[0082] In some examples, the relief structure 31 can be a relief groove which penetrates the adapter 30 along the first direction and can wrap around the blocking member 13. In this way, when the adapter 30 is located between the blocking member 13 and the baffle portion 16, the interference between the adapter 30 and the elastic member 15 is avoided.

[0083] Embodiment Two

[0084] The difference between Embodiment Two and Embodiment One is that:

[0085] Referring to Figure 5 As shown, the four adapters 30 corresponding to the four ink cartridges can be integrally provided. For example, the four adapters 30 can be formed into one integral piece by welding, bonding or one-piece molding, etc. The integral piece is separable from the cartridge bodies 20 of the four ink cartridges. During the process of simultaneously placing the four ink cartridges into the installation cavities 11 of the installation portion 10, the integral piece is located between the baffle portion 16 and the blocking member 13 of the installation cavity 11. During the process of taking the four ink cartridges out of the installation cavities 11, the integral piece remains in the installation cavities 11 and abuts against the baffle portion 16 and the blocking member 13 of the installation cavities 11, respectively. In this way, when the ink cartridges are installed again, the acting portion 23 of the ink cartridges does not need to act on the moving member 14 to unlock the blocking member 13, thereby avoiding the ink cartridges acting on the moving member 14 to unlock the blocking member 13 every time, and thus the service life of the ink cartridges can be improved.

[0086] Embodiment Three

[0087] Referring to Figure 6 and Figure 7 As shown, the difference between the ink cartridge in Embodiment Three and the ink cartridge in Embodiment One is that the ink cartridge can be installed into the installation cavity 11 which accommodates the adapter 30, and the ink cartridge does not need to be provided with an adapter during installation.

[0088] It should be noted that the adapter 30 in the installation cavity 11 can have the same structure as that in Embodiment One.

[0089] In a possible implementation, since the installation cavity 11 is provided with the adapter 30, the blocking member 13 is always in an unlocked state, and the ink cartridge can not be provided with an acting portion. In this way, the cost of the ink cartridge can be reduced.

[0090] In one possible implementation, the upper surface 204 of the cartridge 20 is provided with an engaging portion 60. The rearwardly facing surface of the engaging portion 60 is a locking surface 61. In the state where the cartridge 20 is assembled to the mounting portion 10 of the printing device, the locking surface 61 is a surface that can contact the locking structure in the mounting cavity 11 in the rearward direction. The cartridge is stably assembled into the mounting cavity 11 by the locking surface 61 contacting the locking structure in the mounting cavity 11 in the rearward direction, i.e. the +X axis direction.

[0091] The engaging portion 60 has a horizontal surface 62 and an inclined surface 63 connected in sequence on the top thereof, and the horizontal surface 62 is connected between the locking surface 61 and the inclined surface 63. By the inclined surface 63 and the horizontal surface 62, in the process of assembling the cartridge 20 into the mounting cavity 11, the locking structure in the mounting cavity 11 is smoothly guided to a position further rearward than the locking surface 61 while abutting against the inclined surface 63 and the horizontal surface 62.

[0092] The upper surface 204 of the cartridge 20 is further provided with an operating portion 40. The user presses the operating portion 40 to cause the locking surface 61 to disengage from the locking structure in the mounting cavity 11. The upwardly and forwardly facing surface of the operating portion 40 is an operating surface 41. The operating surface 41 has anti-slip patterns, so that the user can easily recognize the operating surface 41 and the anti-slip patterns also have an anti-slip effect on the user's fingers.

[0093] The cartridge 20 is further provided with a detected member 50 in the accommodating cavity 21. The detected member 50 includes a float 51, and the specific gravity of the float 51 is smaller than that of the ink stored in the accommodating cavity 21. Therefore, in the accommodating cavity 21, the ink generates a buoyant force on the float 51, so that the float 51 floats on the ink. The reduction of the amount of ink in the accommodating cavity 21 affects the movement of the float 51, and thus affects the movement of the detected member 50, and the movement of the detected member 50 affects the intensity of the light received by the light-receiving portion of the remaining amount sensor of the mounting portion 10, so that the purpose of ink amount detection is achieved.

[0094] The upper surface 204 of the cartridge 20 is provided with a light shielding plate 52 between the light-emitting portion and the light-receiving portion of the remaining amount sensor. When the cartridge is assembled, the light shielding plate 52 shields the light signal of the remaining amount sensor of the mounting portion 10.

[0095] In one possible implementation, the upper surface 204 of the cartridge 20 is provided with a chip 70 for communication connection with the printing device.

[0096] The structures of other parts are the same as in the first embodiment.

[0097] Example Four

[0098] The cartridge in the fourth embodiment is the same as the cartridge in the first embodiment. Figure 6 and Figure 7The ink cartridge shown can be an example of the cartridge body in Embodiment Four. In this case, along the +Z-axis direction, the ink outlet 22, the action portion 23 (see Figure 3 the chip 70, and the engaging portion 60 are arranged in sequence.

[0099] In the -X-axis direction, the ink outlet 22 is located in front of the engaging portion 60, the chip 70 is located in front of the engaging portion 60, the action portion 23 is located in front of the engaging portion 60, and the ink outlet 22 is located between the chip 70 and the action portion 23.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
