Technical Field

[0001] This invention relates to the field of inkjet imaging, and more particularly to an ink cartridge that can be detachably mounted to an inkjet imaging device and has a packaging bag. Background Technology

[0002] Ink cartridges are a common office consumable that contain ink used for imaging. To enable inkjet imaging devices (hereinafter referred to as "imaging devices") to know the parameter information of the ink cartridge, a chip that stores the parameter information is usually installed in the ink cartridge. When the ink cartridge is installed in the imaging device, the electrical contacts in the chip make electrical contact with the stylus in the imaging device, thereby establishing a communication connection between the ink cartridge and the imaging device, and the parameter information can be obtained by the imaging device.

[0003] However, when a user removes a new ink cartridge from its packaging and installs it into the imaging device, the electrical contacts may be contaminated by the user's fingers or by dust or impurities suspended in the air, which may prevent the ink cartridge from establishing a communication connection with the imaging device.

[0008] In some embodiments, the chip further includes a substrate, electrical contacts are disposed on the substrate, and the path limiting member further includes a third auxiliary member connecting the substrate and the packaging bag.

[0009] In some implementations, the cleaning component comes into contact with the electrical contact portion during the transition of the packaging bag from an expanded state to a contracted state.

[0010] In some embodiments, the ink cartridge also includes a rotating device connected to the packaging bag, the rotating device being used to cause the packaging bag to tend toward a contracted state.

[0011] In some implementations, the ink cartridge also includes a spool disposed on the housing, and the packaging bag is shrunk by winding around the spool.

[0012] In some embodiments, the housing has a receiving portion inside for accommodating a packaged bag in a folded state.

[0019] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the following embodiments can be combined with each other without conflict.

[0020] [Overall structure of the ink cartridge]

[0021] The ink cartridge 10 can be detachably installed into an imaging device equipped with a stylus, such as... Figure 1 and Figure 2 As shown, the ink cartridge 10 includes a housing and an ink outlet 3, wherein an ink chamber 7 (e.g., ink cavity 7) is formed in the housing and communicates with the ink outlet 3. Figure 4 As shown), the ink outlet 3 is used to discharge ink to the outside of the ink cartridge 10. For example, ink is supplied to the imaging device through the ink outlet 3.

[0022] Specifically, the housing includes a main body 1 and a cover 2 that are connected to each other, and the ink outlet 3 can be set on either the main body 1 or the cover 2.

[0023] Furthermore, the ink cartridge 10 also includes a chip 5 and a chip mounting portion 15. At least a portion of the chip 5 is carried by the chip mounting portion 15. The chip 5 includes a substrate 51, an electrical contact portion 52, and a storage portion. The electrical contact portion 52 is electrically connected to the storage portion. The storage portion stores parameter information such as the model and service life of the ink cartridge 10. The electrical contact portion 52 is used to form an electrical connection with the stylus, thereby establishing a communication connection between the ink cartridge 10 and the imaging device. The parameter information can be obtained by the imaging device.

[0024] In some embodiments, both the electrical contact portion 52 and the storage portion are disposed on the substrate 51. Preferably, the electrical contact portion 52 and the storage portion are located on two different surfaces of the substrate 51, and the electrical contact portion 52 forms an electrical connection by directly contacting the stylus.

[0025] In some embodiments, the storage unit is disposed on the substrate 51, and the electrical contact 52 is disposed at other locations on the ink cartridge 10 according to design requirements, as long as the electrical contact 52 can form an electrical connection with the contact pin.

[0026] In some embodiments, the chip mounting portion 15 is configured as part of the housing, that is, the chip 5 and the chip mounting portion 15 are fixedly disposed relative to the housing.

[0027] In some embodiments, the chip mounting portion 15 is configured as a component that can be movably mounted to the housing, in which case the chip 5 will move relative to the housing along with the chip mounting portion 15.

[0028] Furthermore, the ink cartridge 10 also includes a cleaning component 8 disposed on the housing and a receiving area S for disposing of the cleaning component 8. The receiving area S can be a receiving groove disposed on the housing or a part of the outer surface of the housing. That is, the cleaning component 8 can be accommodated by the receiving groove or can be directly disposed on the outer surface of the housing. When the electrical contact 52 is contaminated, or when the ink cartridge 10 cannot establish a communication connection with the imaging device after it is installed in the imaging device, the user can clean the electrical contact 52 through the cleaning component 8 to ensure that the ink cartridge 10 can establish a stable communication connection with the imaging device.

[0029] In some embodiments, the cleaning component 8 includes multiple different types of cleaning parts, which users can use to remove different contaminants. This embodiment of the invention uses a first cleaning part 81 and a second cleaning part 82 as an example. The first cleaning part 81 and the second cleaning part 82 are used to remove different contaminants. For example, the first cleaning part 81 is an eraser used to remove dust or impurities adhering to the electrical contact part 52, and the second cleaning part 82 is an alcohol pack used to remove dust, ink, or contaminants that the eraser cannot remove from the electrical contact part 52. In this combination, due to the volatility of alcohol, the alcohol pack is generally a disposable item, but the user can still use the eraser to clean the electrical contact part 52.

[0030]

Packaging Bags

[0031] Example 1

[0032] Continue as Figure 1 and Figure 2 As shown, the ink cartridge 10 also includes a packaging bag 4, which is used to accommodate the housing and is configured to switch between a retracted state and an expanded state. In the expanded state, the packaging entrance 42 of the packaging bag 4 is open, and the housing can be accommodated by the packaging space 40 formed inside the packaging bag 4. In the retracted state, the housing is located outside the packaging space 40. At this time, the packaging bag 4 can be accommodated by the housing or located outside the housing, and the packaging entrance 42 can be either open or closed. The present invention does not limit this.

[0033] Taking the orientation of the ink cartridge 10 in this embodiment, which is detachably installed into the imaging device, as an example, the ink cartridge 10 has the following characteristics: Figure 1 As shown above, below, in front, behind, left, and right, the ink cartridge 10 is installed from top to bottom in the vertical direction. The chip mounting portion 15 is configured as at least a portion of the front surface facing forward, or the chip mounting portion 15 is mounted on the front surface, and the electrical contact portion 52 is supported by the front surface. Alternatively, in the front-back direction, the electrical contact portion 52 is opposite to the front surface, and the ink outlet 3 is located on the lower surface facing downward. In other imaging device environments, the ink cartridge 10 can also be installed from back to front in the front-back direction; the present invention does not limit the installation direction of the ink cartridge.

[0034] exist Figure 1 In the diagram, the solid line indicates that the packaging bag 4 is in a contracted state, while the dashed line indicates that the packaging bag 4 is in an unfolded state. The contracted packaging bag 4 is exposed outside the casing. Preferably, the transition direction / unfolding direction of the packaging bag 4 from the contracted state to the unfolded state (e.g., ...) Figure 4 The direction of the packaging bag (r) is not obstructed by the casing, so that the user can quickly unfold the packaging bag.

[0035] In some embodiments, the packaging bag 4 is shrunken by winding it around the reel 14, such as... Figure 1 As shown, the roller 14 is mounted on the housing, and the packaging bag 4 is wound on the roller 14. The user can unroll the packaging bag 4 by pulling the pulled part 41.

[0036] In some embodiments, the spool 14 can be fixed relative to the housing, and the packaging bag 4 is wound around the spool 14. The packaging bag 4 is positioned on the spool 14 by the friction generated between the two. At this time, when the pulled part 41 is pulled, the packaging bag 4 rotates around the spool 14 in the rotation direction r and unfolds.

[0037] In some embodiments, the spool 14 is rotatably arranged relative to the housing. Specifically, the spool 14 is rotatably supported by the housing. In this case, when the pulled part 41 is pulled, the packaging bag 4 will rotate and unfold together with the spool 14 in the rotation direction r.

[0038] In some embodiments, a portion of the packaging bag 4 is fixedly connected to the roll 14 to prevent the packaging bag 4 from detaching from the roll 14 and thus making the packaging bag 4 unusable. For example, the side opposite to the packaging inlet 42 is fixedly connected to the roll 14, so that the volume of the packaging bag 4 can be maximized.

[0039] In some embodiments, the packaging bag 4 is also provided with a closure component for closing the packaging inlet 42 to prevent the shell from coming out of the packaging inlet 42. For example, the closure component is a zipper, snap, etc.

[0040] In some implementations, the sealing component can seal the packaging inlet 42 so that even if ink leaks from the ink outlet 3, the leaked ink will not flow out through the packaging inlet 42, and external dust or impurities will not enter the packaging space 40 through the packaging inlet 42.

[0041] In some embodiments, the spool 14 is configured to have a tendency to rotate in the opposite direction to the rotation direction r. In this case, the ink cartridge 10 is also provided with a rotary device that forces the spool 14 to rotate in the opposite direction to the rotation direction r. Alternatively, the ink cartridge 10 is also provided with a rotary device for causing the packaging bag 4 to have a tendency to switch to a contracted state. For example, a coil spring that cooperates with the spool 14 is provided in the ink cartridge 10. In this way, when the user releases the closure of the closure component, the spool 14 automatically rotates in the opposite direction to the rotation direction r, thereby driving the packaging bag 4 back to the contracted state.

[0042] In some embodiments, the cartridge 10 also includes an auxiliary component 9, which is at least used to improve the speed at which the user removes the cleaning component 8.

[0043] Typically, the volume of the ink cartridge 10 is limited by the space of the ink cartridge mounting section within the imaging device. To prevent the ink cartridge 10 from failing to reach its preset lifespan, the ink chamber 7 needs to be filled with as much ink as possible. In other words, with the volume of the ink cartridge 10 remaining constant, the larger the space of the ink chamber 7, the better. If a groove 16 is provided in the housing for easy removal of the cleaning component 8 (e.g., ...), it can facilitate this process. Figure 1 As shown), this device will inevitably occupy the space of the ink chamber 7. By setting the auxiliary component 9, the present invention can quickly remove the cleaning component 8 without setting the groove 16.

[0044] The auxiliary component 9 includes a first auxiliary member 91 disposed on at least one of the cleaning component 8 and the packaging bag 4, which connects the cleaning component 8 to the packaging bag in response to the packaging bag 4 transitioning from an unfolded state to a retracted state. Specifically, the first auxiliary member 91 connects the cleaning component 8 to the packaging bag, and the cleaning component 8 moves as the packaging bag 4 unfolds, thereby removing the cleaning component 8 from the receiving area S of the housing by the packaging bag 4.

[0045] In a preferred embodiment, the cleaning component 8 and the packaging bag 4 are connected by adhesive. For example, the first auxiliary component 91 is set as double-sided adhesive. When the ink cartridge 10 leaves the factory, the first auxiliary component 91 can be set on the cleaning component 8, or on the packaging bag 4, or the first auxiliary component 91 can be set on both the cleaning component 8 and the packaging bag 4.

[0046] Multiple first auxiliary components 91 can be provided, each corresponding to a cleaning component in the cleaning assembly 8. Alternatively, only one first auxiliary component 91 can be provided. The cleaning components in the cleaning assembly 8 are interconnected, so that after one cleaning component is taken out of the packaging bag 4 through the first auxiliary component 91, the other cleaning components can also be taken out separately.

[0047] In some embodiments, the auxiliary component 9 further includes a second auxiliary component 92 connecting the housing and the packaging bag 4. The second auxiliary component 92 is used to restrict the shrinkage path of the packaging bag 4 when it transitions from the unfolded state to the contracted state. Therefore, the second auxiliary component 92 can also be regarded as a shrinkage path restrictor of the packaging bag 4, so that the packaging bag 4 contracts along a predetermined path. In this way, the removed cleaning component 8 can move along a predetermined path as the packaging bag 4 contracts, ultimately achieving the cleaning of the electrical contact portion 52 by the cleaning component 8.

[0048] In this embodiment, in response to the packaging bag 4 changing from an unfolded state to a retracted state, the cleaning component 8 automatically cleans the electrical contact portion 52, reducing user operation steps and improving the user experience. Preferably, along the retraction path of the packaging bag 4, the packaging inlet 42 will first pass through the receiving area S and then through the electrical contact portion 52. That is, along the retraction path of the packaging bag 4, the electrical contact portion 52 is located downstream of the receiving area S, or the second auxiliary component 92 is located downstream of the first auxiliary component 91. In some embodiments, the second auxiliary component 92 is disposed adjacent to the electrical contact portion 52 / chip 5 / substrate 51 for connecting the housing and the packaging bag 4. Along the retraction path of the packaging bag 4, the second auxiliary component 92 can be disposed at least one upstream and one downstream of the electrical contact portion 52 / chip 5 / substrate 51, as long as it can guide the cleaning component 8 to pass through the electrical contact portion 52.

[0049] In some embodiments, the auxiliary member 9 also includes a third auxiliary member 93 disposed on the substrate 51, which makes the shrinkage path of the packaging bag 4 more precise, that is, ensures that the cleaning component 8 passes through the electrical contact portion 52. Therefore, the third auxiliary member 93 is also formed as part of the shrinkage path limiting member for connecting the substrate 51 and the packaging bag 4.

[0050] In some embodiments, at least one of the second auxiliary component 92 and the third auxiliary component 93 is provided.

[0051] In some embodiments, the second auxiliary component 92 and the third auxiliary component 93 may also be double-sided adhesive. However, it is understood that the first auxiliary component 91, the second auxiliary component 92 and the third auxiliary component 93 may also be wire bonding, that is, the packaging bag 4 is connected to the corresponding component by welding.

[0052] In some embodiments, the cleaning component 8 may also be configured as at least a part of the packaging bag 4, that is, at least a part of the packaging bag 4 has the cleaning function of the cleaning component 8, in which case the first cleaning component 91 may be omitted.

[0053] In some embodiments, it may not be necessary to provide the shrinkage path limiting member. The packaging bag 4 is configured such that when the shell is contained in the receiving space 40 in the packaging bag 4, the packaging inlet 42 does not face the surface where the electrical contact part 52 is provided. In this embodiment, for example, the packaging inlet 42 faces at least one of the upper surface, lower surface, left surface, right surface and rear surface of the shell. In this way, during the process of the packaging bag 4 changing from the unfolded state to the shrinked state, the packaging bag 4 will pass through the electrical contact part 52, thereby realizing automatic cleaning of the electrical contact part 52.

[0054] Example 2

[0055] like Figure 3 and Figure 4 As shown, in this embodiment, the chip mounting part 15 is movably disposed on the housing, and the second auxiliary member 92 is disposed on the chip mounting part 15. Therefore, the second auxiliary member 92 can move relative to the housing along with the chip mounting part 15. Specifically, the second auxiliary member 92 can slide relative to the housing in the vertical direction along with the chip mounting part 15.

[0056] Taking the orientation of the ink cartridge 10 in this embodiment, which is detachably installed into the imaging device, as an example, the ink cartridge 10 has the following characteristics: Figure 3 As shown above, below, in front, behind, left, and right, the ink cartridge 10 is installed from back to front in the front-back direction. The chip mounting part 15 is set as at least a part of the upper surface facing upward, or the chip mounting part 15 is mounted on the upper surface, the electrical contact part 52 is supported by the upper surface, or the electrical contact part 52 is opposite to the upper surface in the up-down direction, and the ink outlet 3 is set on the front surface facing forward.

[0057] Furthermore, the ink cartridge 10 also includes a sealing film 6 disposed between the main body 1 and the cover 2. The sealing film 6 is used to seal the ink cavity 7, so that even if the cover 2 is separated from the main body 1, the ink will not leak. Correspondingly, the packaging bag 4 can be disposed between the detachably connected cover 2 and the main body 1. More precisely, the packaging bag 4 is disposed between the sealing film 6 and the cover 2. The user can remove the packaging bag 4 by separating the cover 2 from the main body 1.

[0058] It can be seen that the packaging bag 4 in the shrunken state can be contained by the shell. In other words, the shell is provided with a receiving part 13 for containing the packaging bag 4 in the shrunken state. Specifically, the receiving part 13 is located inside the shell. For example, in the ink cartridge 10 provided with the sealing film 6, the receiving part 13 is located between the sealing film 6 and the cover 2.

[0059] In some embodiments, the ink cartridge 10 also includes an exposure port 11 communicating with the receiving portion 13, so that the packaging bag 4 contained in the receiving portion can be exposed through the exposure port 11, so that the user can take out or pull the packaging bag 4 through the exposure port 11. Preferably, at least a portion of the pulling portion 41 is located outside the exposure port 11.

[0060] In some embodiments, when the packaging inlet 42 of the packaging bag 4 in the unfolded state does not need to be closed, the packaging bag 4 can also be hung on a specific part in the ink cartridge 10 so that the packaging inlet 42 is in an open state, so that the operator can put accessories of the ink cartridge 10 into the packaging space 40, such as product manuals, auxiliary tools to help users install or remove the chip 5, etc.

[0061] The specific location may be, for example, a corner of the housing or a handle 12 connected to the housing, through which the user can install or remove the ink cartridge 10.

[0062] In this embodiment, the packaging bag 4 can also be configured such that when the housing is accommodated by the accommodating space 40 in the packaging bag 4, the packaging inlet 42 does not face the surface where the electrical contact part 52 is provided. In this embodiment, for example, the packaging inlet 42 faces at least one of the lower surface, left surface, right surface, front surface, and rear surface of the housing. In this way, during the process of the packaging bag 4 changing from the unfolded state to the contracted state, the packaging bag 4 will pass through the electrical contact part 52, thereby realizing automatic cleaning of the electrical contact part 52.

[0063] [Use scenarios for packaging bags]

[0064] Based on the above description, the usage scenarios for packaging bag 4 include:

[0065] In the first case, after the ink in the ink chamber 7 is used up, the user can change the packaging bag 4 from a contracted state to an extended state to form a receiving space 40 that can accommodate the shell. In this way, the user does not have to worry about the residual ink in the ink chamber 7 leaking when transferring the ink cartridge 10 after the ink is used up.

[0066] The second method involves packaging bag 4 being in an unfolded state when ink cartridge 10 leaves the factory. At this time, the housing is located in the packaging space 40. When the user needs to use ink cartridge 10, packaging bag 4 is changed from the unfolded state to the retracted state. After the ink in ink chamber 7 is consumed, the user changes packaging bag 4 from the retracted state to the unfolded state to accommodate the housing.

[0067] [Beneficial Effects]

[0068] 1. In the second usage scenario described above, the packaging material for ink cartridge 10 will be reduced. By printing packaging information on the packaging bag 4, the packaging bag 4 can become a packaging material for packaging ink cartridge 10.

[0069] 2. By setting a rotary device in the ink cartridge 10 that is connected to the packaging bag 4, the packaging bag 4 can automatically switch to a shrinking state, thereby simplifying the user's operation.

[0070] 3. By providing the first auxiliary component 91, the cleaning component 8 moves relative to the housing as the packaging bag 4 transitions from an unfolded state to a retracted state. For example, the cleaning component 8 is automatically removed from the receiving area S of the housing, which not only reduces the user's operating steps but also preserves the volume of the ink chamber 7 as much as possible. The embodiments of the present invention still apply even if the cleaning component 8 is directly mounted on the outer surface of the housing.

[0071] 4. By setting a shrinkage path limiter, the path of the packaging bag 4 from the unfolded state to the shrinkage state can be controlled. During the transition, the cleaning component 8 contacts the electrical contact part 52, so that the cleaning component 8 automatically cleans the electrical contact part 52, which can prevent the ink cartridge 10 from being unable to establish a communication connection with the imaging device due to contamination of the electrical contact part 52.
