Definitions
- the present invention relates to the field of ink-jet printer technologies, and in particular, to an ink cartridge.
- An ink-jet printer is a relatively common printing appliance.
- laser printers have become quite popular, but because maintenance costs of the laser printers are relatively high, ink-jet printers still have a massive share of the market, especially in places such as households, shops, and offices.
- Ink cartridges as consumable appliances for ink-jet printing are also greatly demanded in the market.
- FIG. 1 a relatively common ink cartridge is shown in FIG. 1 .
- An ink cartridge 6 is a consumable appliance that is detachably installed in an installation structure (not shown).
- the ink cartridge 6 includes a handle 61, an engagement portion 62, a chip 63, an ink outlet 64, and a housing 69a.
- the engagement portion 62 is disposed on the handle 61, the handle 61 extends out of the housing 69a, and the handle 61 is elastic and can rotate around a fulcrum 611.
- the engagement portion 62 is a part that can be engaged with the installation structure, to prevent the ink cartridge 6 from moving upward, so that the engagement portion 62 is subject to a downward acting force applied by the installation structure, and the handle 61 is subject to a downward acting force.
- the acting force causes the handle 61 to have a downward rotational torque. Because the handle 61 extends out of the housing 69a, if the torque is applied on the handle 61 for a long time, the handle 61 may have insufficient elasticity or lose the elasticity and cannot be retained at a predetermined position. Consequently, the ink cartridge 6 is fixed at an inaccurate position and cannot be identified by the installation structure, or cannot be fixed in the installation structure. In addition, if the ink cartridge 6 is repeatedly installed multiple times, the handle 61 may lose the elasticity, finally resulting in that the ink cartridge 6 cannot be fixed in the installation structure.
- US2012/056955 A1 discloses an ink cartridge which is detachably installed in an installation structure of a printing device.
- the ink cartridge comprises a housing and a buckle disposed on the housing.
- the present invention provides an ink cartridge, so that the ink cartridge can be more reliably fixed in an installation structure.
- An ink cartridge is provided according to independent claim 1 and dependent claims 2 to 27.
- the buckle is clamped with or separated from the force application component, so as to install the ink cartridge in the printing device or detach the ink cartridge from the printing device.
- a manner of fixing the ink cartridge by using the handle is abandoned.
- the ink cartridge is more reliably installed, and it is less prone to a case in which the ink cartridge cannot be fixed or cannot be identified, so that the ink cartridge can be more reliably fixed in the installation structure of the printing device.
- FIG. 2 and FIG. 3 are schematic diagrams of an ink cartridge according to Embodiment 1A.
- an ink cartridge 2 basically has a shape of a cuboid.
- the ink cartridge 2 may have a shape such as an oval or a circle.
- the ink cartridge 2 basically has a shape of a cuboid, and the ink cartridge 2 includes six surfaces that are respectively a first surface 2a, a second surface 2b, a third surface 2c, a fourth surface 2d, a fifth surface 2e, and a sixth surface 2f.
- the first surface 2a is opposite to the second surface 2b; the third surface 2c and the fourth surface 2d are opposite to each other and are basically perpendicular to the first surface 2a; and the fifth surface 2e and the sixth surface 2f are opposite to each other and are basically perpendicular to the first surface 2a and the third surface 2c.
- the ink cartridge 2 includes a detent 21, a buckle 22, a chip 23, an ink outlet 24, a position limiting portion 25, an elastic component 26 (which may be defined as a first elastic component) (shown in FIG. 4 ), a limiting portion 27 (shown in FIG. 4 ), and a housing 29.
- the detent 21 is disposed on the fourth surface 2d, and the detent 21 has a detent surface 211, and can be engaged with a corresponding position of an installation structure 3, to prevent the ink cartridge 2 from moving upward.
- the chip 23 is disposed on a slope that is obliquely disposed between the first surface 2a and the third surface 2c.
- the chip 23 is fixed on a chip rack 23a, and includes a terminal 231 that is electrically connected to a corresponding part of the installation structure 3.
- the chip 23 stores information such as ink quantity information, an ink type, and a manufacturer, and can be electrically connected to a contact pin 33 of an installation structure 3 of a printer.
- the ink outlet 24 is a protrusion disposed on the first surface 2a, and can provide ink to the printer.
- the position limiting portion 25 has a position limiting surface 251, and can limit movement of the ink cartridge 2 in a left-right direction.
- the housing 29 includes a chamber 292 and a cover 291.
- the chamber 292 has an ink chamber 293 that can store ink, and the cover 291 is welded on the chamber 292, so that the ink chamber 293 can be in a sealed state.
- the elastic component 26 may be silica gel, an elastic metal sheet, a spring, or the like, and is preferably a spring in this embodiment.
- the buckle 22 includes an engagement portion 221 and a limited portion 223.
- the elastic component 26 is connected to the buckle 22 along a stretching direction of the elastic component 26. In this way, the buckle 22 can move along the stretching direction of the elastic component 26 under the action of an external force.
- the limiting portion 27 is disposed on the housing 29 at a position opposite to the limited portion 223. An angle is formed between movement directions of the limited portion 223 and the buckle 22. When the buckle 22 moves along the stretching direction of the elastic component 26, the limited portion 223 can be clamped with or separated from the limiting portion 27.
- the angle between the movement directions of the limited portion 223 and the buckle 22 may be less than 90 degrees or equal to 90 degrees or greater than 90 degrees, which can all achieve an objective of the present invention.
- the limited portion 223 is inclined toward the elastic component 26 relative to a vertical direction (inclined to the left when seen from FIG. 4 ). This facilitates movement between the limited portion 223 and the buckle 22.
- the ink cartridge is installed in the installation structure, the installation structure is disposed in the printing device, and a force application component (not shown) is disposed at a position in the printing device (not shown) close to the engagement portion 221.
- the force application component is disposed opposite to the engagement portion 221, and a shape of the force application component may be designed in a matching manner according to a shape of the engagement portion 221.
- the force application component may be set to have a structure including a notch or an engagement hole, so that the engagement portion 221 and the force application component can be clamped, to fix the ink cartridge in the printing device.
- the engagement portion 221 may have a regular shape such as a clamping shoulder or a hook.
- the force application component is correspondingly changed, to achieve an objective that the engagement portion 221 and the force application component can be engaged. Details are not described herein. Further, under the action of an external force, the force application component may be separated from the engagement portion 221, to unfix the ink cartridge from the printing device, so as to detach the ink cartridge to replace the ink cartridge. For a specific process, refer to the following descriptions.
- the engagement portion 221 is disposed between the elastic component 26 and the force application component.
- the second surface 2b is pressed to insert the engagement portion 221 into the notch or the engagement hole of the force application component, to complete installation of the ink cartridge.
- fixing of the ink cartridge on the printing device mainly depends on a connection between the engagement portion 221 and the force application component. Specifically, after the ink cartridge is completely installed, the limited portion 223 is separated from the limiting portion 27, and the limited portion 223 is located between the limiting portion 27 and the force application component.
- a user applies an external force on the force application component to cause the force application component to move toward a direction of the elastic component 26, so that the buckle 22 moves toward the direction of the elastic component 26 and compresses the elastic component 26.
- the limited portion 223 reaches a position of the limiting portion 27, the external force applied on the force application component is removed.
- the force application component restores to an original position under the action of an elastic force, and the buckle 22 moves toward a direction of the force application component under the action of a resilience force of the elastic component 26.
- the limited portion 223 is clamped with the limiting portion 27 to prevent the buckle 22 from continuing moving toward the direction of the force application component, and the force application component completely restores to the original position and is already separated from the engagement portion 221.
- an elastic force applied by the contact pin of the installation structure 3 on the chip 23 causes the ink cartridge 2 to bounce upward and to be detached from the installation structure 3, so as to unfix the ink cartridge from the printing device, and complete detachment of the ink cartridge.
- the buckle 22 finally restores to a natural state. More specifically, when the ink cartridge is in an installed state, the limited portion 223 is not clamped with the limiting portion 27. When the ink cartridge is taken out, the limited portion 223 is first clamped with the limiting portion 27 and then separated from the limiting portion 27, so that when the user removes the external force, the force application component restores to the original position.
- the buckle 22 is clamped in the limiting portion 27 for a short time due to the limited portion 223, so that the buckle 22 is separated from the force application component.
- a person skilled in the art understands that, during movement of the buckle 22 toward the direction of the elastic component 26, a case in which the limited portion 223 exceeds the position of the limiting portion 27 may occur. In this case, after the external force applied on the force application component is removed, the limited portion 223 still reaches the position of the limiting portion 27 during restoration and is clamped with the limiting portion 27 for a short time. This can also achieve the objective of the present invention.
- FIG. 5 is a sectional view of an ink cartridge according to Embodiment 2A.
- FIG. 5 is a schematic diagram when a buckle 22 is located at a first position (that is, located at a position of a first limiting portion 271).
- FIG. 6 is a schematic diagram when the buckle 22 is located at a second position (that is, located at a position of a second limiting portion 272).
- the buckle 22 includes an engagement portion 221, a connection portion 222, and a limited portion 223.
- An elastic component 26 may be silica gel, an elastic metal sheet, a spring, or the like, and is preferably a spring in this embodiment.
- a limiting portion 27 includes the first limiting portion 271 and the second limiting portion 272, and the first limiting portion 271 is located between the second limiting portion and a force application component.
- the limiting portion 27 is a groove disposed on a housing 29.
- the connection portion 222 abuts against the elastic component 26, the connection portion 222 abuts against the engagement portion 221, and the limited portion 223 abuts against the connection portion 222.
- the connection portion 222 may not be disposed on the buckle 22. As shown in FIG. 5 , when the limited portion 223 is limited by the first limiting portion 271, the buckle 22 (the limited portion 223) is located at the first position.
- an elastic force applied by the elastic component 26 on the buckle 22 is less than or equal to an acting force applied by the first limiting portion 271 on the limited portion 223. Therefore, the limited portion 223 on the buckle 22 is not detached from the first limiting portion 271 under the action of an elastic force, that is, the buckle 22 may be retained at the first position. As shown in FIG. 6 , when the limited portion 223 is limited by the second limiting portion 272, the buckle 22 (the limited portion 223) is located at the second position. In this case, the elastic force applied by the elastic component 26 on the buckle 22 is greater than an acting force applied by the second limiting portion 272 on the limited portion 223.
- the buckle 22 when the limited portion 223 on the buckle 22 is located at the second position, the buckle 22 can only be retained at the second position for a short time, and finally, due to the elastic force of the elastic component 26, the buckle 22 (the limited portion 223) restores to the first position.
- the buckle 22 restores to the first position.
- a person of ordinary skill in the art may understand that, there may be one limited portion 223, or there may be multiple limited portions 223 arranged along the circumference of the connection portion 222 on the buckle 22.
- a magnitude of the elastic force of the elastic component 26 may have different changes based on designs of materials and shapes.
- factors affecting the force include a trimming die amount of a metal material, a wire diameter of the spring, a medium diameter of the spring, and an effective coil number.
- the elastic component 26 is silica gel
- the elastic force mainly depends on a coefficient of elasticity of a silica gel material.
- an acting force between the limited portion 223 and the first limiting portion 271 may have different changes by changing material types of the limited portion 223 and the first limiting portion 271 and controlling a depth by which the limited portion 223 is clamped in the first limiting portion 271.
- the acting force between the limited portion 223 and the first limiting portion 271 becomes larger; on the contrary, the acting force between the limited portion 223 and the first limiting portion 271 becomes smaller.
- the acting force between the limited portion 223 and the second limiting portion 272 may have different changes in a similar manner. A person skilled in the art may make different changes on this basis. Details are not described herein.
- FIG. 7 and FIG. 8 are schematic diagrams of the buckle according to Embodiment 2A.
- a reinforcement portion may be disposed on the buckle 22.
- a first reinforcement portion 224 and a second reinforcement portion 225 are disposed on the buckle 22.
- a person of ordinary skill in the art may understand that, there may be one reinforcement portion or two or more reinforcement portions, as long as that the buckle 22 can achieve a force balance at the first position.
- a groove matching the first reinforcement portion 224 and the second reinforcement portion 225 is provided on a part of the housing that is connected to the first reinforcement portion 224 and the second reinforcement portion 225, to satisfy that the reinforcement portion can move in the groove in a process of taking out the ink cartridge 2.
- the reinforcement portion may not be disposed.
- FIG. 9 is a schematic local diagram when the ink cartridge is installed in an installation structure according to Embodiment 2A.

- a distance from the first limiting portion 271 to the elastic component 26 is greater than a distance from the second limiting portion 272 to the elastic component 26, and a distance from the first limiting portion 271 to the lever 31 is less than a distance from the second limiting portion 272 to the lever 31.
- An elastic force that is applied by the elastic component 26 on the buckle 22 when the limited portion 223 is located at the second position is greater than an elastic force that is applied by the elastic component 26 on the buckle 22 when the limited portion 223 is located at the first position.

- a user pushes a push portion 312 of the lever 31, the push portion 312 drives the buckle 42 to move toward a direction of the elastic component 46, and the buckle 42 reaches the second position from the first position, that is, the first limited portion 423 is separated from the first limiting portion 471, and the second limited portion 426 is engaged with the second limiting portion 472. Then, the user releases the push portion 312 of the lever 31. After a push force applied on the push portion 312 is removed, the lever 31 immediately restores to an original position. Because the second limited portion 426 is limited by the second limiting portion 472 for a short time, the buckle 42 can be retained at the second position for a short time. In addition, an elastic force applied by a contact pin 33 on a chip 43 causes the ink cartridge 4 to bounce upward and to be detached from the installation structure 3. Finally, the user can take out the ink cartridge 4 from the installation structure 3.

- the buckle 52 includes a first limited portion 523 and a second limited portion 524.
- the first limited portion 523 is a protrusion, and can match the first limiting portion 571 on a housing, to cause the ink cartridge to be retained at a first position.
- the second limited portion 524 is an arcuate recess, and the second limiting portion 572 is a cylinder that has an arcuate end and that matches the second limited portion 524.

Then, the user releases the push portion 312 of the lever 31. After a push force applied on the push portion 312 is removed, the lever 31 immediately restores to an original position. Because the second limited portion 524 is limited by the second limiting portion 572 for a short time, the buckle 52 can be retained at the second position for a short time. In addition, an elastic force applied by a contact pin 33 on a chip 53 causes the ink cartridge 5 to bounce upward and to be detached from the installation structure 3. Finally, the user can take out the ink cartridge 5 from the installation structure 3.
- an axial direction of the second spring 58 may also be set to a horizontal direction, that is, a direction parallel to a first surface and a second surface, or may also be set to a downward inclined direction, which both can resolve a technical problem to be resolved by the technical solution, and can achieve a technical effect of the technical solution.

- a user presses the second surface 7b to cause the ink cartridge to move toward directions of the first surface 7a and the third surface 7c.
- the abutting portion 34 applies, on the telescopic portion 726, a reacting force toward the fourth surface 7d or toward the second surface 7b and the fourth surface 7d, that is, the reacting force applied by the abutting portion 34 is toward a compression direction of an elastic component (not shown in FIG. 16 and FIG. 17 ).

- the force application component 32 compresses the buckle 22 to move along a compression direction of the first elastic component 41.
- a position (referred to as a "second position 322" below) at which the force application component 32 is connected to the fourth elastic component 42 moves along a compression direction of the fourth elastic component 42.

That is, the first position 321 and the second position 322 are at two sides of a rotation axis (not shown) of the force application component 32 along the vertical direction. Therefore, the movement directions of the first position 321 and the second position 322 are opposite to each other.
- the buckle 22 rebounds and restores to an original position under the action of the first elastic component 41, and the force application component 32 rebounds and restores to an original position under the action of the fourth elastic component 42.

- the ink cartridge bounces upward the under the action of the elastic force of the contact pin 33. More specifically, as shown in FIG. 20 , the chip 23 is disposed on a slope that is obliquely disposed between the first surface 2a and the third surface 2c. The chip 23 is fixed on a chip rack 23a.
- the chip 23 includes a storage unit that stores information such as ink quantity information, an ink type, and a manufacturer, and a terminal, and the terminal can be electrically connected to the contact pin 33 on the installation structure 3.
- the ink outlet 24 is a protrusion disposed on the first surface 2a, and can provide ink to the ink-jet printer.

- the part of the buckle 22 that is located in the housing 29 forms an accommodation groove (not numbered in the figure), and the first elastic component 41 is disposed in the accommodation groove.
- a size of the accommodation groove is adjusted, so that the size of the accommodation groove matches a size of the first elastic component 41.
- the force application component 32 may be set to have a structure including an engagement hole 323 (or a notch).
- the engagement portion 221 is engaged with the engagement hole 323 (or the notch), so that the buckle 22 can be engaged with the force application component, so as to fix the ink cartridge in the installation structure 3.
- the engagement portion of the buckle 22 may have a regular shape such as a clamping shoulder or a hook.
- the force application component 32 is correspondingly changed, to achieve an objective that the engagement portion and the force application component can be engaged. Details are not described herein.
- the first elastic component 41 is directly fixed on the third surface 2c, and then the buckle 22 is fixedly connected to the first elastic component 41.
- fixing is directly performed through welding; for another example, a fixing block are disposed on each of the third surface 2c and the buckle 22, and then the first elastic component 41 is fixed on the fixing block.
- the second surface 2b is pressed to cause the ink cartridge to move downward as a whole, until a state shown in FIG. 24 is reached. That is, the buckle 22 is engaged with the force application component 32. In addition, the chip 23 abuts against the contact pin 33. In this case, the contact pin 33 applies an upward resilience force on the ink cartridge, but because the engagement portion 221 is engaged with the engagement hole 323 (or the notch), the ink cartridge is fixed in the installation structure 3.
- an external force F is applied by an operator at the first position 321 of the force application component 32.

- the buckle 22 and the force application component 32 restore to the original positions at the same time, and a movement direction when the buckle 22 restores to the original position is the same as a movement direction when the first position 321 restores to the original position.
- a first state during separation between the ink cartridge and the installation structure shown in FIG. 25 can be achieved, that is, the buckle 22 is just separated from the force application component 32, but the contact pin 33 is still not separated from the chip 23.
- a second state during separation between the ink cartridge and the installation structure is reached.
- the ink cartridge bounces upward under the action of an elastic force of the contact pin 33.
- the chip 23 no longer compress the contact pin 33, and the engagement portion 221 of the buckle 22 and the engagement hole 323 (or the notch) of the force application component 32 are misplaced, to implement complete separation between the buckle 22 and the force application component 32.
- the contact pin 33 causes the entire ink cartridge to bounce, and then, the ink cartridge is taken out from the installation structure 3, to complete an entire detachment process.
- magnitudes of the elastic forces of the first elastic component 41 and the fourth elastic component 42 affect the acceleration when the buckle 22 and the force application component 32 restore to the original positions.
- Factors affecting the elastic forces include specifications of the first elastic component 41 and the fourth elastic component 42 and compression degrees of the first elastic component 41 and the fourth elastic component 42.
- the first elastic component 41 and the fourth elastic component 42 are both metal spiral springs, and preferably, a metal material may select straight carbon steel, stainless iron, or stainless steel, the factors affecting the elastic force include a trimming die amount of the metal material, a wire diameter of the spring, a medium diameter of the spring, and an effective coil number.
- the elastic force mainly depends on a coefficient of elasticity of a silica gel material. Further, under a condition that the specifications of the first elastic component 41 and the fourth elastic component 42 are given, if the first elastic component 41 and the fourth elastic component 42 are compressed to a higher degree, the elastic forces are larger.
- masses of the buckle 22 and the force application component 32 may be changed in a matching manner to adjust the acceleration when the buckle 22 and the force application component 32 restore to the original positions.
- a larger elastic force of the first elastic component 41 indicates a smaller mass of the buckle 22 and higher acceleration during restoration to the original position; or a smaller elastic force of the first elastic component 41 indicates a larger mass of the buckle 22 and smaller acceleration during restoration to the original position.
- a principle of adjusting the acceleration when the force application component 32 restores to the original position is similar to this. Details are not described herein again.
- initial acceleration when the force application component 32 restores to the original position is greater than initial acceleration when the buckle 22 restores to the original position. This more facilitates fast detachment of the ink cartridge. That is, at an initial stage after the external force is removed, the force application component 32 completes separation from the buckle 22. In this case, the ink cartridge bounces under the action of the elastic force of the contact pin 33, and then the ink cartridge can be taken out.
- the first elastic component 41 has a wire diameter of 0.4 mm, a developed length of 14 mm, a medium diameter of 4.1 mm, an effective coil number of 8, and a pitch of 1.6 mm;
- the fourth elastic component 42 has a wire diameter of 0.4 mm, a developed length of 9 mm, a medium diameter of 2.6 mm, an effective coil number of 9, and a pitch of 1 mm; and a magnitude of the external force is 8-10 N.

FIG. 1 . Anink cartridge 6 is a consumable appliance that is detachably installed in an installation structure (not shown). Theink cartridge 6 includes ahandle 61, anengagement portion 62, achip 63, anink outlet 64, and a housing 69a. Theengagement portion 62 is disposed on thehandle 61, thehandle 61 extends out of the housing 69a, and thehandle 61 is elastic and can rotate around afulcrum 611. Theengagement portion 62 is a part that can be engaged with the installation structure, to prevent theink cartridge 6 from moving upward, so that theengagement portion 62 is subject to a downward acting force applied by the installation structure, and thehandle 61 is subject to a downward acting force. The acting force causes thehandle 61 to have a downward rotational torque. Because thehandle 61 extends out of the housing 69a, if the torque is applied on thehandle 61 for a long time, thehandle 61 may have insufficient elasticity or lose the elasticity and cannot be retained at a predetermined position. Consequently, theink cartridge 6 is fixed at an inaccurate position and cannot be identified by the installation structure, or cannot be fixed in the installation structure. In addition, if theink cartridge 6 is repeatedly installed multiple times, thehandle 61 may lose the elasticity, finally resulting in that theink cartridge 6 cannot be fixed in the installation structure. -

FIG. 2 andFIG. 3 are schematic diagrams of an ink cartridge according to Embodiment 1A. As shown inFIG. 2 andFIG. 3 , anink cartridge 2 basically has a shape of a cuboid. A person of ordinary skill in the art may understand that, according to an actual requirement, theink cartridge 2 may have a shape such as an oval or a circle. In this embodiment, theink cartridge 2 basically has a shape of a cuboid, and theink cartridge 2 includes six surfaces that are respectively afirst surface 2a, asecond surface 2b, athird surface 2c, afourth surface 2d, afifth surface 2e, and asixth surface 2f. Thefirst surface 2a is opposite to thesecond surface 2b; thethird surface 2c and thefourth surface 2d are opposite to each other and are basically perpendicular to thefirst surface 2a; and thefifth surface 2e and thesixth surface 2f are opposite to each other and are basically perpendicular to thefirst surface 2a and thethird surface 2c. - The
ink cartridge 2 includes adetent 21, abuckle 22, achip 23, anink outlet 24, aposition limiting portion 25, an elastic component 26 (which may be defined as a first elastic component) (shown inFIG. 4 ), a limiting portion 27 (shown inFIG. 4 ), and ahousing 29. Thedetent 21 is disposed on thefourth surface 2d, and thedetent 21 has adetent surface 211, and can be engaged with a corresponding position of aninstallation structure 3, to prevent theink cartridge 2 from moving upward. Thechip 23 is disposed on a slope that is obliquely disposed between thefirst surface 2a and thethird surface 2c. Thechip 23 is fixed on achip rack 23a, and includes a terminal 231 that is electrically connected to a corresponding part of theinstallation structure 3. Thechip 23 stores information such as ink quantity information, an ink type, and a manufacturer, and can be electrically connected to acontact pin 33 of aninstallation structure 3 of a printer. Theink outlet 24 is a protrusion disposed on thefirst surface 2a, and can provide ink to the printer. Theposition limiting portion 25 has aposition limiting surface 251, and can limit movement of theink cartridge 2 in a left-right direction. Thehousing 29 includes achamber 292 and acover 291. Thechamber 292 has anink chamber 293 that can store ink, and thecover 291 is welded on thechamber 292, so that theink chamber 293 can be in a sealed state. - Further, as shown in
FIG. 4 , theelastic component 26 may be silica gel, an elastic metal sheet, a spring, or the like, and is preferably a spring in this embodiment. Thebuckle 22 includes anengagement portion 221 and alimited portion 223. Theelastic component 26 is connected to thebuckle 22 along a stretching direction of theelastic component 26. In this way, thebuckle 22 can move along the stretching direction of theelastic component 26 under the action of an external force. Specifically, the limitingportion 27 is disposed on thehousing 29 at a position opposite to thelimited portion 223. An angle is formed between movement directions of thelimited portion 223 and thebuckle 22. When thebuckle 22 moves along the stretching direction of theelastic component 26, thelimited portion 223 can be clamped with or separated from the limitingportion 27. More specifically, the angle between the movement directions of thelimited portion 223 and thebuckle 22 may be less than 90 degrees or equal to 90 degrees or greater than 90 degrees, which can all achieve an objective of the present invention. Preferably, thelimited portion 223 is inclined toward theelastic component 26 relative to a vertical direction (inclined to the left when seen fromFIG. 4 ). This facilitates movement between thelimited portion 223 and thebuckle 22. - A person skilled in the art understands that, during actual application, the ink cartridge is installed in the installation structure, the installation structure is disposed in the printing device, and a force application component (not shown) is disposed at a position in the printing device (not shown) close to the
engagement portion 221. The force application component is disposed opposite to theengagement portion 221, and a shape of the force application component may be designed in a matching manner according to a shape of theengagement portion 221. Using theengagement portion 221 shown inFIG. 4 as an example, in this case, the force application component may be set to have a structure including a notch or an engagement hole, so that theengagement portion 221 and the force application component can be clamped, to fix the ink cartridge in the printing device. In some other variant embodiments, theengagement portion 221 may have a regular shape such as a clamping shoulder or a hook. In addition, the force application component is correspondingly changed, to achieve an objective that theengagement portion 221 and the force application component can be engaged. Details are not described herein. Further, under the action of an external force, the force application component may be separated from theengagement portion 221, to unfix the ink cartridge from the printing device, so as to detach the ink cartridge to replace the ink cartridge. For a specific process, refer to the following descriptions. - Further, the
engagement portion 221 is disposed between theelastic component 26 and the force application component. During installation of the ink cartridge, thesecond surface 2b is pressed to insert theengagement portion 221 into the notch or the engagement hole of the force application component, to complete installation of the ink cartridge. A person skilled in the art understands that, fixing of the ink cartridge on the printing device mainly depends on a connection between theengagement portion 221 and the force application component. Specifically, after the ink cartridge is completely installed, thelimited portion 223 is separated from the limitingportion 27, and thelimited portion 223 is located between the limitingportion 27 and the force application component. - Further, during detachment of the ink cartridge, a user applies an external force on the force application component to cause the force application component to move toward a direction of the
elastic component 26, so that thebuckle 22 moves toward the direction of theelastic component 26 and compresses theelastic component 26. When thelimited portion 223 reaches a position of the limitingportion 27, the external force applied on the force application component is removed. In this case, the force application component restores to an original position under the action of an elastic force, and thebuckle 22 moves toward a direction of the force application component under the action of a resilience force of theelastic component 26. However, during restoration, thelimited portion 223 is clamped with the limitingportion 27 to prevent thebuckle 22 from continuing moving toward the direction of the force application component, and the force application component completely restores to the original position and is already separated from theengagement portion 221. In this case, an elastic force applied by the contact pin of theinstallation structure 3 on thechip 23 causes theink cartridge 2 to bounce upward and to be detached from theinstallation structure 3, so as to unfix the ink cartridge from the printing device, and complete detachment of the ink cartridge. Specifically, during detachment, when thelimited portion 223 is clamped with the limitingportion 27, a resilience force applied by theelastic component 26 on thelimited portion 223 is greater than an acting force applied by the limitingportion 27, so that after thebuckle 22 is clamped by the limitingportion 27 for a short time, thebuckle 22 finally restores to a natural state. More specifically, when the ink cartridge is in an installed state, thelimited portion 223 is not clamped with the limitingportion 27. When the ink cartridge is taken out, thelimited portion 223 is first clamped with the limitingportion 27 and then separated from the limitingportion 27, so that when the user removes the external force, the force application component restores to the original position. Thebuckle 22 is clamped in the limitingportion 27 for a short time due to thelimited portion 223, so that thebuckle 22 is separated from the force application component. A person skilled in the art understands that, during movement of thebuckle 22 toward the direction of theelastic component 26, a case in which thelimited portion 223 exceeds the position of the limitingportion 27 may occur. In this case, after the external force applied on the force application component is removed, thelimited portion 223 still reaches the position of the limitingportion 27 during restoration and is clamped with the limitingportion 27 for a short time. This can also achieve the objective of the present invention. - Embodiment 2A:
FIG. 5 is a sectional view of an ink cartridge according to Embodiment 2A.FIG. 5 is a schematic diagram when abuckle 22 is located at a first position (that is, located at a position of a first limiting portion 271).FIG. 6 is a schematic diagram when thebuckle 22 is located at a second position (that is, located at a position of a second limiting portion 272). Specifically, thebuckle 22 includes anengagement portion 221, aconnection portion 222, and alimited portion 223. Anelastic component 26 may be silica gel, an elastic metal sheet, a spring, or the like, and is preferably a spring in this embodiment. A limitingportion 27 includes the first limitingportion 271 and the second limitingportion 272, and the first limitingportion 271 is located between the second limiting portion and a force application component. In this embodiment, the limitingportion 27 is a groove disposed on ahousing 29. Theconnection portion 222 abuts against theelastic component 26, theconnection portion 222 abuts against theengagement portion 221, and thelimited portion 223 abuts against theconnection portion 222. A person skilled in the art may understand that, theconnection portion 222 may not be disposed on thebuckle 22. As shown inFIG. 5 , when thelimited portion 223 is limited by the first limitingportion 271, the buckle 22 (the limited portion 223) is located at the first position. In this case, an elastic force applied by theelastic component 26 on thebuckle 22 is less than or equal to an acting force applied by the first limitingportion 271 on thelimited portion 223. Therefore, thelimited portion 223 on thebuckle 22 is not detached from the first limitingportion 271 under the action of an elastic force, that is, thebuckle 22 may be retained at the first position. As shown inFIG. 6 , when thelimited portion 223 is limited by the second limitingportion 272, the buckle 22 (the limited portion 223) is located at the second position. In this case, the elastic force applied by theelastic component 26 on thebuckle 22 is greater than an acting force applied by the second limitingportion 272 on thelimited portion 223. Therefore, when thelimited portion 223 on thebuckle 22 is located at the second position, thebuckle 22 can only be retained at the second position for a short time, and finally, due to the elastic force of theelastic component 26, the buckle 22 (the limited portion 223) restores to the first position. A person of ordinary skill in the art may understand that, there may be onelimited portion 223, or there may be multiplelimited portions 223 arranged along the circumference of theconnection portion 222 on thebuckle 22. - Specifically, a magnitude of the elastic force of the
elastic component 26 may have different changes based on designs of materials and shapes. For example, if theelastic component 26 is a metal spiral spring, factors affecting the force include a trimming die amount of a metal material, a wire diameter of the spring, a medium diameter of the spring, and an effective coil number. For another example, if theelastic component 26 is silica gel, the elastic force mainly depends on a coefficient of elasticity of a silica gel material. More specifically, an acting force between thelimited portion 223 and the first limitingportion 271 may have different changes by changing material types of thelimited portion 223 and the first limitingportion 271 and controlling a depth by which thelimited portion 223 is clamped in the first limitingportion 271. For example, if a distance by which thelimited portion 223 extends into the first limitingportion 271 becomes longer, the acting force between thelimited portion 223 and the first limitingportion 271 becomes larger; on the contrary, the acting force between thelimited portion 223 and the first limitingportion 271 becomes smaller. Correspondingly, the acting force between thelimited portion 223 and the second limitingportion 272 may have different changes in a similar manner. A person skilled in the art may make different changes on this basis. Details are not described herein. -
FIG. 7 andFIG. 8 are schematic diagrams of the buckle according to Embodiment 2A. To ensure that thebuckle 22 can be stably fixed at the first position and to balance the elastic force applied by theelastic component 26, a reinforcement portion may be disposed on thebuckle 22. As shown inFIG. 7 andFIG. 8 , in this embodiment, afirst reinforcement portion 224 and asecond reinforcement portion 225 are disposed on thebuckle 22. A person of ordinary skill in the art may understand that, there may be one reinforcement portion or two or more reinforcement portions, as long as that thebuckle 22 can achieve a force balance at the first position. A groove matching thefirst reinforcement portion 224 and thesecond reinforcement portion 225 is provided on a part of the housing that is connected to thefirst reinforcement portion 224 and thesecond reinforcement portion 225, to satisfy that the reinforcement portion can move in the groove in a process of taking out theink cartridge 2. A person of ordinary skill in the art may understand that, if it is ensured that thebuckle 22 can achieve a force balance, the reinforcement portion may not be disposed. -
FIG. 9 is a schematic local diagram when the ink cartridge is installed in an installation structure according to Embodiment 2A. As shown inFIG. 9 , a force application component does not need to be separately disposed in a printing device, but amovable lever 31 included in aninstallation structure 3 is used as a force application component. The first limitingportion 271 is located between the second limitingportion 272 and the force application component (that is, the lever 31). A distance from the first limitingportion 271 to theelastic component 26 is greater than a distance from the second limitingportion 272 to theelastic component 26, and a distance from the first limitingportion 271 to thelever 31 is less than a distance from the second limitingportion 272 to thelever 31. An elastic force that is applied by theelastic component 26 on thebuckle 22 when thelimited portion 223 is located at the second position is greater than an elastic force that is applied by theelastic component 26 on thebuckle 22 when thelimited portion 223 is located at the first position. A schematic diagram of thelever 31 is shown inFIG. 10 . Thelever 31 includes rotation axes 313 and 314, anengagement hole 311, and apush portion 312. Thelever 31 can rotate around the rotation axes 313 and 314. In a state in which theink cartridge 2 is installed in theinstallation structure 3, an axial direction of the elastic component 26 (which is preferably a spring) is a horizontal direction. In a state in which theink cartridge 2 is installed in theinstallation structure 3, theengagement portion 221 is engaged with theengagement hole 311 of thelever 31, to limit upward movement of theink cartridge 2. In a process of taking out theink cartridge 2, first, a user pushes thepush portion 312 of thelever 31, thepush portion 312 drives thebuckle 22 to move toward a direction of theelastic component 26, and thelimited portion 223 on thebuckle 22 reaches the second limitingportion 272 from the first limitingportion 271, that is, thebuckle 22 reaches the second position from the first position. Then, the user releases thepush portion 312 of thelever 31. After a push force applied on thepush portion 312 is removed, thelever 31 immediately restores to an original position. Because thelimited portion 223 is limited by the second limitingportion 272 for a short time (that is, thelimited portion 223 is clamped in the second limitingportion 272 for a short time), thebuckle 22 can be retained at the second position for a short time. In addition, an elastic force applied by acontact pin 33 on achip 23 causes theink cartridge 2 to bounce upward and to be detached from theinstallation structure 3. Finally, the user can take out theink cartridge 2 from theinstallation structure 3. - A person skilled in the art understands that, the
buckle 22 shown in each ofFIG. 7 andFIG. 8 and thelever 31 shown inFIG. 10 are also applicable to Embodiment 1A. Details are not described herein. Specifically, in Embodiment 2A, in a state in which theink cartridge 2 is not installed in theinstallation structure 3, thelimited portion 223 is limited at the first position of the first limitingportion 271 by the limitingportion 27. It may be learned from the foregoing Embodiment 1A and Embodiment 2A that, in the technical solutions of the present invention, a fixed manner of positioning the ink cartridge by using the handle in the Background is abandoned, to prevent a case in which the ink cartridge is fixed at an inaccurate position and cannot be identified by the installation structure or the ink cartridge cannot be fixed in the installation structure. - In a variant embodiment, the
buckle 22 and thehousing 29 may be integrally formed or separately formed and then assembled, and a requirement in the technical solution can be met as long as movement of thebuckle 22 is not affected. In this embodiment, it may be learned fromFIG. 5 andFIG. 9 that, thebuckle 22 including theengagement portion 221 and thehousing 29 are separate portions. Thebuckle 22 and thehousing 29 may be separately manufactured and then assembled. Thebuckle 22 has a function of positioning theink cartridge 2. Therefore, preferably, material hardness of thebuckle 22 is higher than that of thehousing 29. Preferably, thebuckle 22 and thehousing 29 are both obtained through injection molding and are both plastic products. Preferably, a material of thebuckle 22 is ABS, and a material of thehousing 29 is PP. -
FIG. 11 is a schematic local diagram when anink cartridge 4 is installed in aninstallation structure 3 according to Embodiment 3A. Abuckle 42 includes a firstlimited portion 423 and a secondlimited portion 426 that are disposed opposite to each other. A limitingportion 47 includes a first limitingportion 471 and a second limitingportion 472. Along a direction of anelastic component 46 toward a lever 31 (that is, a force application component), a distance from the first limitingportion 471 to theelastic component 46 is greater than a distance from the second limitingportion 472 to theelastic component 46, to ensure that during movement of anengagement portion 421 toward theelastic component 46, first, the firstlimited portion 423 is clamped with the first limitingportion 471, and then, the secondlimited portion 426 is clamped with the second limitingportion 472. Specifically, in a state in which the firstlimited portion 423 is limited by the first limitingportion 471, thebuckle 42 is located at a first position. In this case, an elastic force applied by theelastic component 46 on thebuckle 42 is less than or equal to an acting force applied by the first limitingportion 471 on the firstlimited portion 423, that is, the first position is a position at which thebuckle 42 achieves a force balance. In a state in which the secondlimited portion 426 is limited by the second limitingportion 472, thebuckle 42 is located at a second position. In this case, an elastic force of theelastic component 46 is greater than an acting force applied by the second limitingportion 472 on the secondlimited portion 426, that is, an elastic force applied by theelastic component 46 on thebuckle 42 is greater than the acting force applied by the second limitingportion 472 on the secondlimited portion 426. That is, thebuckle 42 is in an unbalanced state, and in the unbalanced state, the second limitingportion 472 is temporarily limited by the secondlimited portion 426, and thebuckle 42 may be temporarily located at the second position, but finally, thebuckle 42 restores to the first position (that is, a position of the first limiting portion 471) under the action of the elastic force of theelastic component 46. In a state in which theink cartridge 4 is not installed in theinstallation structure 3, the firstlimited portion 423 is limited at the first position by the limitingportion 47. -
FIG. 12 is a schematic diagram of the buckle according to Embodiment 3A. To ensure that thebuckle 42 can be stably fixed at the first position, a reinforcement portion may be disposed on thebuckle 42. As shown inFIG. 12 , in this embodiment, afirst reinforcement portion 424 and asecond reinforcement portion 425 are disposed on thebuckle 42. A groove matching thefirst reinforcement portion 424 and thesecond reinforcement portion 425 is provided on a part of the housing that is connected to thefirst reinforcement portion 424 and thesecond reinforcement portion 425, to satisfy that the reinforcement portion can move in the groove in a process of taking out theink cartridge 4. The firstlimited portion 423 is connected to aconnection portion 422 by using afirst arm 423a, the secondlimited portion 426 is connected to theconnection portion 422 by using asecond arm 426a, and similarly, thefirst reinforcement portion 424 and thesecond reinforcement portion 425 are also connected to theconnection portion 422 by using an arm. - The first
limited portion 423 and the secondlimited portion 426 on thebuckle 42 may be both disposed on a samefirst arm 423a. This also can achieve a technical effect of the technical solution, and thesecond arm 426a is omitted in this structure. - In a process of taking out the
ink cartridge 4, first, a user pushes apush portion 312 of thelever 31, thepush portion 312 drives thebuckle 42 to move toward a direction of theelastic component 46, and thebuckle 42 reaches the second position from the first position, that is, the firstlimited portion 423 is separated from the first limitingportion 471, and the secondlimited portion 426 is engaged with the second limitingportion 472. Then, the user releases thepush portion 312 of thelever 31. After a push force applied on thepush portion 312 is removed, thelever 31 immediately restores to an original position. Because the secondlimited portion 426 is limited by the second limitingportion 472 for a short time, thebuckle 42 can be retained at the second position for a short time. In addition, an elastic force applied by acontact pin 33 on achip 43 causes theink cartridge 4 to bounce upward and to be detached from theinstallation structure 3. Finally, the user can take out theink cartridge 4 from theinstallation structure 3. - The remaining part is similar to Embodiment 2A. Repeated descriptions are not provided herein again.

FIG. 13 is a schematic diagram when an ink cartridge is installed in an installation structure according to Embodiment 4A.FIG. 14 and FIG. 15 are schematic partial diagrams of the ink cartridge according to Embodiment 4A. An ink cartridge 5 includes anelastic component 56, a buckle 52 (including anengagement portion 521 and a connection portion 522), a first limitingportion 571, a second limitingportion 572, and a second spring 58 (which may be defined as a third elastic component). Similar to Embodiment 3A, along a direction of theelastic component 56 toward a lever 31 (that is, a force application component), a distance from the first limitingportion 571 to theelastic component 56 is greater than a distance from the second limitingportion 572 to theelastic component 56. Thebuckle 52 includes a firstlimited portion 523 and a secondlimited portion 524. The firstlimited portion 523 is a protrusion, and can match the first limitingportion 571 on a housing, to cause the ink cartridge to be retained at a first position. The secondlimited portion 524 is an arcuate recess, and the second limitingportion 572 is a cylinder that has an arcuate end and that matches the secondlimited portion 524. In a process of taking out the ink cartridge 5, first, a user pushes apush portion 312 of thelever 31, thepush portion 312 drives thebuckle 52 to move toward a direction of theelastic component 56, and thebuckle 52 reaches a second position from the first position, that is, the firstlimited portion 523 is separated from the first limitingportion 571, and the secondlimited portion 524 is engaged with the second limitingportion 572. Then, the user releases thepush portion 312 of thelever 31. After a push force applied on thepush portion 312 is removed, thelever 31 immediately restores to an original position. Because the secondlimited portion 524 is limited by the second limitingportion 572 for a short time, thebuckle 52 can be retained at the second position for a short time. In addition, an elastic force applied by acontact pin 33 on achip 53 causes the ink cartridge 5 to bounce upward and to be detached from theinstallation structure 3. Finally, the user can take out the ink cartridge 5 from theinstallation structure 3. - The remaining part is similar to Embodiment 3A. Repeated descriptions are not provided herein again.
- A person of ordinary skill in the art may understand that, an axial direction of the
second spring 58 may also be set to a horizontal direction, that is, a direction parallel to a first surface and a second surface, or may also be set to a downward inclined direction, which both can resolve a technical problem to be resolved by the technical solution, and can achieve a technical effect of the technical solution. -
FIG. 16 is a schematic diagram of anink cartridge 7 according to Embodiment 5A of the present invention. Theink cartridge 7 includes afirst surface 7a and asecond surface 7b that are opposite to each other, and athird surface 7c and afourth surface 7d that are opposite to each other. It may be learned fromFIG. 16 that, different from the foregoing embodiment, abuckle 72 of theink cartridge 7 shown inFIG. 16 includes twotelescopic portions 726. A person skilled in the art understands that, for compositions of and position relationships between other parts of theink cartridge 7, refer toFIG. 2 andFIG. 3 , and details are not described herein again. Specifically, thebuckle 72 includes anengagement portion 721, aconnection portion 722, a limitingportion 723, and thetelescopic portions 726. The twotelescopic portions 726 are located at two sides of theconnection portion 722, and along a direction of thesecond surface 7b toward thefirst surface 7a, thetelescopic portions 726 are located below theengagement portion 721. Specifically,FIG. 17 is a schematic local diagram when theink cartridge 7 is installed in aninstallation structure 3. With reference toFIG. 16 and FIG. 17 , it may be learned that, theinstallation structure 3 includes an abuttingportion 34 that is disposed opposite to thetelescopic portion 726. During installation of the ink cartridge, a user presses thesecond surface 7b to cause the ink cartridge to move toward directions of thefirst surface 7a and thethird surface 7c. After thetelescopic portion 726 abuts against the abuttingportion 34, the abuttingportion 34 applies, on thetelescopic portion 726, a reacting force toward thefourth surface 7d or toward thesecond surface 7b and thefourth surface 7d, that is, the reacting force applied by the abuttingportion 34 is toward a compression direction of an elastic component (not shown inFIG. 16 and FIG. 17 ). In this case, because pressure applied by the user on thesecond surface 7b is not removed, the reacting force applied by the abuttingportion 34 finally transfers to the elastic component (not shown) and compresses the elastic component. A person skilled in the art understands that, compared with the foregoing embodiment, in this embodiment, it is more labor-saving during installation. - In another variant embodiment, according to different sizes of the installation structure, the abutting portion that matches the
telescopic portion 726 may be another fixing component in theinstallation structure 3, as long as the abutting portion is opposite to thetelescopic portion 726 during installation. - Further,
FIG. 18 and FIG. 19 are schematic diagrams of thebuckle 72. Thetelescopic portion 726 has an inverted-L shape, and thetelescopic portion 726 extends downward along a vertical direction. Preferably, the abuttingportion 34 is inclined relative to thetelescopic portion 726. This more facilitates the abuttingportion 34 to apply, on thetelescopic portion 726, a reacting force toward thesecond surface 7b andfourth surface 7d. Preferably,reinforcement portions buckle 72 and have functions similar to those of thereinforcement portions FIG. 8 . Details are not described herein again. In a change, the abuttingportion 34 may be parallel to thetelescopic portion 726. In this way, the reacting force applied by the abuttingportion 34 on thetelescopic portion 726 is toward thefourth surface 7d. This can also achieve an objective of this embodiment. In another change, thetelescopic portion 726 is inclined relative to the vertical direction, and correspondingly, the abuttingportion 34 may be parallel to thetelescopic portion 726 or may be inclined relative to thetelescopic portion 726. Details are not described herein again. - A person skilled in the art understands that, the ink cartridge involved in the present invention is disposed in an ink-jet printer. A main outline of the ink cartridge is formed by a
housing 29. As shown inFIG. 20 , thehousing 29 basically has a shape of a cube. Specifically, according to an actual requirement, thehousing 29 may have a shape such as an oval or a circle. More specifically, thehousing 29 includes six surfaces. Afirst surface 2a is opposite to asecond surface 2b; and athird surface 2c and afourth surface 2d are opposite to each other and are basically perpendicular to thefirst surface 2a. More specifically, thehousing 29 generally includes a chamber and a cover (not shown). The chamber has an ink chamber that can store ink, and the cover is welded on the chamber, so that the ink chamber can be in a sealed state. - Further, the ink cartridge includes a first
elastic component 41 connected to thehousing 29. The firstelastic component 41 is connected to abuckle 22 along a stretching direction. The firstelastic component 41 may be silica gel, an elastic metal sheet, a spring, or the like, and is preferably a spring in this specific implementation. In this way, thebuckle 22 can move along the stretching direction of the firstelastic component 41. Specifically, the firstelastic component 41 is disposed along a horizontal direction, and thebuckle 22 can perform reciprocating movement along the horizontal direction. A specific connection manner of thebuckle 22 and the firstelastic component 41 is described in detail below. - Further, the
buckle 22 can be engaged with or separated from aforce application component 32 on the ink-jet printer. Theforce application component 32 is connected to the ink-jet printer by using a fourthelastic component 42. The fourthelastic component 42 is disposed opposite to the firstelastic component 41, and along a vertical direction, the fourthelastic component 42 is located below the firstelastic component 41. The fourthelastic component 42 may be silica gel, an elastic metal sheet, a spring, or the like, and is preferably a spring in this specific implementation. The fourthelastic component 42 may be disposed along the horizontal direction, or may be obliquely disposed relative to the horizontal direction. Specifically, under the action of an external force, theforce application component 32 can rotate toward a direction of thebuckle 22 in a vertical plane. - Further, in the vertical direction, a position (referred to as a "
first position 321" below) at which the external force is applied on theforce application component 32 is basically aligned with a position of thebuckle 22, that is, relative to thefirst surface 2a, a height from thefirst position 321 to thefirst surface 2a is basically the same as a height from thebuckle 22 to thefirst surface 2a. In this case, theforce application component 32 compresses thebuckle 22 to move along a compression direction of the firstelastic component 41. Correspondingly, a position (referred to as a "second position 322" below) at which theforce application component 32 is connected to the fourthelastic component 42 moves along a compression direction of the fourthelastic component 42. In addition, because the firstelastic component 41 is disposed opposite to the fourthelastic component 42, movement directions of thefirst position 321 and thesecond position 322 are opposite to each other. Specifically, as shown inFIG. 20 , thefirst position 321 is at the top of theforce application component 32, and thesecond position 322 is at the bottom of theforce application component 32. That is, thefirst position 321 and thesecond position 322 are at two sides of a rotation axis (not shown) of theforce application component 32 along the vertical direction. Therefore, the movement directions of thefirst position 321 and thesecond position 322 are opposite to each other. More specifically, when the external force is applied at thefirst position 321, in a state in which theforce application component 32 stops rotating, when the external force is removed, thefirst position 321 moves toward a direction away from thebuckle 22, thebuckle 22 rebounds and restores to an original position under the action of the firstelastic component 41, and theforce application component 32 rebounds and restores to an original position under the action of the fourthelastic component 42. A movement direction when thebuckle 22 restores to the original position is the same as a rotation direction when theforce application component 32 restores to the original position. - In a specific embodiment, as shown in
FIG. 21 , the ink-jet printer includes aninstallation structure 3. Theforce application component 32 is a rotatable lever disposed on theinstallation structure 3. The fourthelastic component 42 is disposed on theinstallation structure 3. Theforce application component 32 is connected to theinstallation structure 3 by using the fourthelastic component 42. Specifically, the ink cartridge includes achip 23, and theinstallation structure 3 includes acontact pin 33. The chip 23 (shown inFIG. 24 ) is disposed opposite to thecontact pin 33. When thebuckle 22 is engaged with theforce application component 32, thechip 23 is in contact with thecontact pin 33, and thecontact pin 33 applies an upward elastic force along the vertical direction on thechip 23 and the ink cartridge. After thebuckle 22 is separated from theforce application component 32, the ink cartridge bounces upward the under the action of the elastic force of thecontact pin 33. More specifically, as shown inFIG. 20 , thechip 23 is disposed on a slope that is obliquely disposed between thefirst surface 2a and thethird surface 2c. Thechip 23 is fixed on achip rack 23a. Thechip 23 includes a storage unit that stores information such as ink quantity information, an ink type, and a manufacturer, and a terminal, and the terminal can be electrically connected to thecontact pin 33 on theinstallation structure 3. Theink outlet 24 is a protrusion disposed on thefirst surface 2a, and can provide ink to the ink-jet printer. - In a connection manner in this specific embodiment,
FIG. 22 and FIG. 23 are detailed diagrams of the firstelastic component 41 and thebuckle 22. With reference toFIG. 20 , it may be learned that, one part of thebuckle 22 extends into thehousing 29 and is clamped in thehousing 29. Thebuckle 22 includes anengagement portion 221 and extends out of thehousing 29. The part of thebuckle 22 that is located in thehousing 29 forms an accommodation groove (not numbered in the figure), and the firstelastic component 41 is disposed in the accommodation groove. A person skilled in the art understands that, a size of the accommodation groove is adjusted, so that the size of the accommodation groove matches a size of the firstelastic component 41. In this way, the firstelastic component 41 may not be fixed on thebuckle 22 and thehousing 29, but abuts against both thebuckle 22 and thehousing 29. A person skilled in the art understands that, as shown inFIG. 21 , theforce application component 32 may be set to have a structure including an engagement hole 323 (or a notch). Theengagement portion 221 is engaged with the engagement hole 323 (or the notch), so that thebuckle 22 can be engaged with the force application component, so as to fix the ink cartridge in theinstallation structure 3. In some other variant embodiments, the engagement portion of thebuckle 22 may have a regular shape such as a clamping shoulder or a hook. In addition, theforce application component 32 is correspondingly changed, to achieve an objective that the engagement portion and the force application component can be engaged. Details are not described herein. - In a variant connection manner (not shown), the first
elastic component 41 is directly fixed on thethird surface 2c, and then thebuckle 22 is fixedly connected to the firstelastic component 41. There are many specific fixing manners, for example, fixing is directly performed through welding; for another example, a fixing block are disposed on each of thethird surface 2c and thebuckle 22, and then the firstelastic component 41 is fixed on the fixing block. These all are the prior art, and details are not described herein. - Further, during installation of the ink cartridge, the
second surface 2b is pressed to cause the ink cartridge to move downward as a whole, until a state shown inFIG. 24 is reached. That is, thebuckle 22 is engaged with theforce application component 32. In addition, thechip 23 abuts against thecontact pin 33. In this case, thecontact pin 33 applies an upward resilience force on the ink cartridge, but because theengagement portion 221 is engaged with the engagement hole 323 (or the notch), the ink cartridge is fixed in theinstallation structure 3. - Further, when the ink cartridge needs to be detached, as shown in
FIG. 24 , an external force F is applied by an operator at thefirst position 321 of theforce application component 32. Under the action of the external force F, theforce application component 32 rotates, and thefirst position 321 of theforce application component 32 moves along a direction of thebuckle 22. Under the action of theforce application component 32, thebuckle 22 moves along a compression direction of the firstelastic component 41, and thesecond position 322 of theforce application component 32 moves along a compression direction of the fourthelastic component 42. After the external force is removed, thebuckle 22 and theforce application component 32 restore to the original positions at the same time, and a movement direction when thebuckle 22 restores to the original position is the same as a movement direction when thefirst position 321 restores to the original position. In this case, provided that it is ensured that acceleration when theforce application component 32 restores to the original position is greater than acceleration when thebuckle 22 restores to the original position, in a process in which thebuckle 22 and theforce application component 32 restore to the original positions, a first state during separation between the ink cartridge and the installation structure shown inFIG. 25 can be achieved, that is, thebuckle 22 is just separated from theforce application component 32, but thecontact pin 33 is still not separated from thechip 23. - Further, after the first state is entered, a second state during separation between the ink cartridge and the installation structure is reached. When the
buckle 22 is separated from theforce application component 32, the ink cartridge bounces upward under the action of an elastic force of thecontact pin 33. As shown inFIG. 26 , thechip 23 no longer compress thecontact pin 33, and theengagement portion 221 of thebuckle 22 and the engagement hole 323 (or the notch) of theforce application component 32 are misplaced, to implement complete separation between thebuckle 22 and theforce application component 32. In addition, thecontact pin 33 causes the entire ink cartridge to bounce, and then, the ink cartridge is taken out from theinstallation structure 3, to complete an entire detachment process. - Further, a person skilled in the art understands that, magnitudes of the elastic forces of the first
elastic component 41 and the fourthelastic component 42 affect the acceleration when thebuckle 22 and theforce application component 32 restore to the original positions. Factors affecting the elastic forces include specifications of the firstelastic component 41 and the fourthelastic component 42 and compression degrees of the firstelastic component 41 and the fourthelastic component 42. For example, if the firstelastic component 41 and the fourthelastic component 42 are both metal spiral springs, and preferably, a metal material may select straight carbon steel, stainless iron, or stainless steel, the factors affecting the elastic force include a trimming die amount of the metal material, a wire diameter of the spring, a medium diameter of the spring, and an effective coil number. For another example, if the firstelastic component 41 and the fourthelastic component 42 are both silica gel, the elastic force mainly depends on a coefficient of elasticity of a silica gel material. Further, under a condition that the specifications of the firstelastic component 41 and the fourthelastic component 42 are given, if the firstelastic component 41 and the fourthelastic component 42 are compressed to a higher degree, the elastic forces are larger. - Further, masses of the
buckle 22 and theforce application component 32 may be changed in a matching manner to adjust the acceleration when thebuckle 22 and theforce application component 32 restore to the original positions. A person skilled in the art understands that, a larger elastic force of the firstelastic component 41 indicates a smaller mass of thebuckle 22 and higher acceleration during restoration to the original position; or a smaller elastic force of the firstelastic component 41 indicates a larger mass of thebuckle 22 and smaller acceleration during restoration to the original position. Corresponding, a principle of adjusting the acceleration when theforce application component 32 restores to the original position is similar to this. Details are not described herein again. - In a preferred embodiment, initial acceleration when the
force application component 32 restores to the original position is greater than initial acceleration when thebuckle 22 restores to the original position. This more facilitates fast detachment of the ink cartridge. That is, at an initial stage after the external force is removed, theforce application component 32 completes separation from thebuckle 22. In this case, the ink cartridge bounces under the action of the elastic force of thecontact pin 33, and then the ink cartridge can be taken out. Multiple specific embodiments are provided below. Specifically, in the following multiple embodiments, the firstelastic component 41 has a wire diameter of 0.4 mm, a developed length of 14 mm, a medium diameter of 4.1 mm, an effective coil number of 8, and a pitch of 1.6 mm; the fourthelastic component 42 has a wire diameter of 0.4 mm, a developed length of 9 mm, a medium diameter of 2.6 mm, an effective coil number of 9, and a pitch of 1 mm; and a magnitude of the external force is 8-10 N. A person skilled in the art may derive more implementation solutions with reference to the following embodiments. - Embodiment 1: The mass of the
buckle 22 is 0.31 g, and the mass of theforce application component 32 is 0.45 g. After the firstelastic component 41 is compressed under the action of the external force, if the external force is removed, an elastic force applied by the firstelastic component 41 on thebuckle 22 is 3 N, an elastic force applied by the fourthelastic component 42 on theforce application component 32 is 12 N, the initial acceleration when thebuckle 22 restores to the original position is 9.6 m/s2, and the initial acceleration when theforce application component 32 restores to the original position is 26.6 m/s2. - Embodiment 2: The mass of the
buckle 22 is 0.38 g, and the mass of theforce application component 32 is 0.51 g. After the firstelastic component 41 is compressed under the action of the external force, if the external force is removed, an elastic force applied by the firstelastic component 41 on thebuckle 22 is 2.5 N, an elastic force applied by the fourthelastic component 42 on theforce application component 32 is 8 N, the initial acceleration when thebuckle 22 restores to the original position is 6.57 m/s2, and the initial acceleration when theforce application component 32 restores to the original position is 15.69 m/s2. - Embodiment 3: The mass of the
buckle 22 is 0.38 g, and the mass of theforce application component 32 is 0.51 g. After the firstelastic component 41 is compressed under the action of the external force, if the external force is removed, an elastic force applied by the firstelastic component 41 on thebuckle 22 is 2.5 N, an elastic force applied by the fourthelastic component 42 on theforce application component 32 is 10 N, the initial acceleration when thebuckle 22 restores to the original position is 6.57 m/s2, and the initial acceleration when theforce application component 32 restores to the original position is 19.61 m/s2. - Embodiment 4: The mass of the
buckle 22 is 0.38 g, and the mass of theforce application component 32 is 0.58g. After the firstelastic component 41 is compressed under the action of the external force, if the external force is removed, an elastic force applied by the firstelastic component 41 on thebuckle 22 is 2.5 N, an elastic force applied by the fourthelastic component 42 on theforce application component 32 is 8 N, the initial acceleration when thebuckle 22 restores to the original position is 6.57 m/s2, and the initial acceleration when theforce application component 32 restores to the original position is 13.79 m/s2. - Embodiment 5: The mass of the
buckle 22 is 0.38 g, and the mass of theforce application component 32 is 0.58g. After the firstelastic component 41 is compressed under the action of the external force, if the external force is removed, an elastic force applied by the firstelastic component 41 on thebuckle 22 is 2.5 N, an elastic force applied by the fourthelastic component 42 on theforce application component 32 is 10 N, the initial acceleration when thebuckle 22 restores to the original position is 6.57 m/s2, and the initial acceleration when theforce application component 32 restores to the original position is 17.24 m/s2. - Embodiment 6: The mass of the
buckle 22 is 0.6 g, and the mass of theforce application component 32 is 0.65 g. After the firstelastic component 41 is compressed under the action of the external force, if the external force is removed, an elastic force applied by the firstelastic component 41 on thebuckle 22 is 2.4 N, the initial acceleration when the buckle restores to the original position is 4 m/s2, an elastic force applied by the fourthelastic component 42 on theforce application component 32 is 6.5 N, and the initial acceleration when theforce application component 32 restores to the original position is 10 m/s2. - Further, a person skilled in the art understands that, with reference to the foregoing five embodiments, it may be learned that, the elastic force applied by the first
elastic component 41 on the buckle is 2.4-3 N, and the elastic force applied by the fourthelastic component 42 on theforce application component 32 is 6.5-12 N. When a value of the mass of the buckle is 0.31-0.6 g, the initial acceleration when the buckle restores to the original position is 4-9.6 m/s2, and when the value of the mass of theforce application component 32 is 0.45-0.65 g, the initial acceleration when theforce application component 32 restores to the original position is 10-26.6 m/s2. It may be learned from the above that, a maximum value of the initial acceleration when the buckle restores to the original position is 9.6 m/s2, it is still less than a minimum value being 10 m/s2 of the initial acceleration when theforce application component 32 restores to the original position. Therefore, within the foregoing value range, an objective of the present invention can be achieved. A person skilled in the art understands that, not all experimental data is listed in this specification, but according to the common sense in the art, these experimental solutions can all be implemented, and details are not described herein. - In another embodiment, the mass of the
buckle 22 is 0.4 g, and the mass of theforce application component 32 is 0.53 g. After a firstelastic component 26 is compressed under the action of the external force, if the external force is removed, an elastic force applied by the firstelastic component 26 on thebuckle 22 is 2.5 N, an elastic force applied by the second elastic component on theforce application component 32 is 10 N, the initial acceleration when thebuckle 22 restores to the original position is 6.25 m/s2, and the initial acceleration when theforce application component 32 restores to the original position is 18.86 m/s2. - Further, when the mass of the
force application component 32 needs to be increased, as shown inFIG. 27 , preferably, the mass is increased by increasing a width of thefirst position 321. In this way, the ink cartridge can be more conveniently detached. - As shown in
FIG. 28 , the ink cartridge further includes apressing portion 28 and a secondelastic component 26a. In this embodiment, thepressing portion 28 is connected to the limitingportion 27, and a through hole on thebuckle 22 is used as thelimited portion 223. When theink cartridge 2 is not installed in theinstallation structure 3, theelastic component 26 abuts against thebuckle 22, theelastic component 26 is in a compressed state, and the limitingportion 27 is engaged with thelimited portion 223, to ensure that thebuckle 22 is not detached from theink cartridge 2. The limitingportion 27 abuts against the secondelastic component 26a, the secondelastic component 26a is in a compressed state, and another limiting mechanism (for example, a spacing groove and an active block) is used to ensure that thepressing portion 28 is not detached from theink cartridge 2. - When the
ink cartridge 2 is installed in theinstallation structure 3, first, the detent 21 (not shown inFIG. 28 ) is engaged with a corresponding part of theinstallation structure 3. Next, the user presses with a hand an upper surface of the pressing portion 28 (referring to an arrow direction inFIG. 28 ), thepressing portion 28 moves downward, and the limitingportion 27 is separated from afirst wall 2231 of thelimited portion 223, thebuckle 22 moves towards the direction of theforce application component 32, theengagement portion 221 is inserted into theengagement hole 311, the limitingportion 27 abuts against thelimited portion 223, and the limitingportion 27 is limited in a state shown inFIG. 29 . Then the user releases the hand, and the installation is completed. - When the
ink cartridge 2 needs to be taken out from theinstallation structure 3, as shown inFIG. 30 , the user pushes thepush portion 312 in theforce application component 32. Theforce application component 32 rotates round the rotation axes 313 and 314. Apressure application portion 316 of theforce application component 32 pushes and presses thebuckle 22 to move toward the direction of theelastic component 26. In addition, when asecond wall 2232 of thelimited portion 223 is detached from the limitingportion 27, under the action of the elastic force of the secondelastic component 26a, the limitingportion 27 moves upward, and abuts against thefirst wall 2231 of thelimited portion 223. In this case, the user releases the hand, theforce application component 32 restores to the original position, and theengagement portion 221 on thebuckle 22 is detached from theengagement hole 311. In addition, the elastic force applied by thecontact pin 33 on thechip 23 causes theink cartridge 2 to bounce upward and to be detached from theinstallation structure 3. Finally, the user can take out theink cartridge 2 from theinstallation structure 3, to reach a state shown inFIG. 31 . -
FIG. 32 is a schematic diagram of anotherinstallation structure 3. Theinstallation structure 3 includes a rotationalforce application component 32, anink duct 32b, and aslot 33b.FIG. 34 is a schematic diagram of theforce application component 32. In addition to same parts of the force application component in Embodiment 1A to Embodiment 5A, theforce application component 32 includes anengagement hole 311 combined by afirst engagement hole 3111, asecond engagement hole 3112, and athird engagement hole 3113, and anengagement protrusion 315 combined by afirst engagement protrusion 3151 and asecond engagement protrusion 3152.FIG. 35 is a schematic diagram of the ink cartridge in this embodiment. Thebuckle 22 includes theconnection portion 222 and the engagement portion 221 (including afirst engagement portion 2211, asecond engagement portion 2212, and a third engagement portion 2213 (which may be respectively engaged with thefirst engagement hole 3111, thesecond engagement hole 3112, and the third engagement hole 3113)).FIG. 36 is a schematic diagram when theink cartridge 2 is installed in theinstallation structure 3. - When the
ink cartridge 2 needs to be taken out from theinstallation structure 3, the user pushes thepush portion 312 of theforce application component 32, theforce application component 32 rotates, and thepressure application portion 316 pushes the stressedportion 2221 on theconnection portion 222, to drive thebuckle 22 to move. Subsequently, a movement process described in Embodiment 1A to Embodiment 5A and Embodiment C is generated. - The installation structure is the same as the installation structure in Embodiment 2E.
-
FIG. 36 andFIG. 37 are schematic diagrams in this embodiment. The ink cartridge includes aconnection tongue 226 that extends downward. Theconnection tongue 226 is connected to theengagement portion 221 and theconnection portion 222. Theengagement portion 221 includes afirst engagement portion 2211 and asecond engagement portion 2212 that are respectively engaged with afirst engagement protrusion 3151 and asecond engagement protrusion 3152. - When the
ink cartridge 2 needs to be taken out from theinstallation structure 3, the user pushes thepush portion 312 of theforce application component 32, theforce application component 32 rotates, and thepressure application portion 316 pushes the stressedportion 2221 on theconnection portion 222, to drive thebuckle 22 to move. Subsequently, a movement process described in Embodiment 1A to Embodiment 5A and Embodiment C is generated. - An unlocking manner: It may be learned from a figure in
FIG. 38 (theforce application component 32 inFIG. 37 is separately taken out) that, thepressure application portion 316 and theengagement protrusion 315 are located at a same side of therotation axis 313. Therefore, when theforce application component 32 rotates, movement directions of thepressure application portion 316 and theengagement protrusion 315 are a same direction. When the user releases the hand, refer to a relationship between the limiting portion and the limited portion in Embodiment 1A to Embodiment 5A: Thebuckle 22 moves to the right, the limiting portion is clamped with the limited portion, thebuckle 22 is in a stopped state, theengagement portion 221 is detached from theengagement protrusion 315, and under the action of the elastic force of the contact pin, theink cartridge 2 bounces, and gets rid of theinstallation structure 3. Refer to embodiment C: Acceleration for resilience forces of thebuckle 22 and theforce application component 32 is different. Theengagement protrusion 315 restores to the original position before theengagement portion 221, and the two are detached. In addition, because of the acting force of the contact pin, theink cartridge 2 bounces. - This is applicable to the installation structure in Embodiment 2E.
-
FIG. 40 is a schematic diagram of matching between the ink cartridge and the installation structure according to Embodiment 4E. Theengagement portion 221 and theconnection portion 222 are both disposed on the handle 22b. When theink cartridge 2 needs to be taken out from theinstallation structure 3, the user pushes thepush portion 312 of theforce application component 32, theforce application component 32 rotates, and thepressure application portion 316 pushes the stressedportion 2221 on theconnection portion 222, to drive the handle 22b to rotate. After the user releases the hand, acceleration for a resilience force of theforce application component 32 is greater than the acceleration of theengagement portion 221. Therefore, during restoration of theforce application component 32 and the handle 22b, the two are separated, and under the action of the elastic force of the contact pin, theink cartridge 2 bounces. - In this embodiment, the stressed
portion 2221 does not need to be disposed in a manner of protruding/over protruding from theforce application component 32, thereby preventing intervention between the stressedportion 2221 and parts in the printer, for example, a friction or a collision, that is caused due to over protrusion of the stressedportion 2221. -
FIG. 41 is a schematic diagram of matching between the ink cartridge and the installation structure according to Embodiment 5E. The structure described in Embodiment 4E is used, is applicable to the installation structure described in Embodiment 1A to Embodiment 5A. - Process descriptions thereof are the same as those of Embodiment 4E, and only applicable installation structures are different.
- The foregoing Embodiment 4E and Embodiment 5E can resolve the following problem in the Background: Referring to
FIG. 3 in the patent application with publication no.CN201620194360.4 FIG. 13 in the patent application exemplarily shows a schematic partial diagram of a printer. An ink cartridge and the installation structure are placed inside the printer. If the pushing portion is disposed above the first buffering portion, intervention between the pushing portion and parts in the printer, for example, a friction or a collision is caused. To prevent generation of such a problem, heights and sizes of the installation structure and the ink cartridge need to be reduced, but a case of insufficient ink in the ink cartridge is caused. - A person of ordinary skill in the art may understand that, an axial direction of the elastic component may also be set to a horizontal direction, that is, a direction parallel to the first surface and the second surface, or may also be set to a downward inclined direction, which both can resolve a technical problem to be resolved by the technical solution, and can achieve a technical effect of the technical solution.
- The scope of the invention is defined by the claims.
