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

[0002] An ink cartridge is installed in a printer's mounting cavity, supplying ink to the printer. Existing ink cartridges have a chip mounted on their top surface. This chip is higher than other components on the top surface, making the chip the first to be damaged when the cartridge is impacted, rendering it unusable. Furthermore, the cost of the chip is significantly higher than that of other components, such as the cartridge body. Consequently, repair costs for damaged chips are high.

[0003] Utility Model Content

[0004] The present application provides an ink cartridge, which is used to solve the technical problem that when the ink cartridge is impacted, the chip is easily damaged first.

[0005] An embodiment of the present application provides an ink cartridge that is detachably mounted in a mounting cavity of a printing device. The ink cartridge comprises:

[0006] a box body, the box body being provided with an ink storage cavity for storing ink, the box body having a top surface and a rear surface;

[0007] a handle, the handle being disposed on the top surface and being rotatable relative to the box body;

[0008] A chip is arranged on the top surface and is lower than the rotation point of the handle along the height direction of the ink cartridge.

[0009] In a specific embodiment, the ink cartridge has a light-shielding portion fixedly arranged on the top surface, and the light-shielding portion is made of an opaque material; along the height direction of the ink cartridge, the highest point of the handle is higher than the light-shielding portion, and at least part of the light-shielding portion is higher than the chip.

[0010] In a specific embodiment, two light-shielding portions are provided, and a light-transmitting area is formed between the two light-shielding portions.

[0011] In a specific embodiment, the handle has a first state and a second state, and the handle can rotate relative to the box body around a rotation point to switch the handle between the first state and the second state; the highest point of the handle when in the first state is higher than the highest point of the handle when in the second state.

[0012] In a specific embodiment, along the height direction of the ink cartridge, a projection of the handle on the top surface does not protrude beyond the rear surface.

[0013] In a specific embodiment, the handle has a protrusion, and the protrusion is used to contact the positioning shaft in the installation cavity, and the positioning shaft drives the handle to change from the first state to the second state.

[0014] In a specific embodiment, the protrusion is provided with a guide surface and a limiting surface, the guide surface is used to enable the positioning shaft to move along it, and the limiting surface is used to abut against the positioning shaft.

[0015] In a specific embodiment, the box body has a hollow groove portion, and the hollow groove portion is arranged between the top surface and the rear surface.

[0016] In a specific embodiment, a connecting portion is provided on the top surface, the handle is connected to the top surface via the connecting portion, and the rotation point is located at an end of the handle close to the connecting portion.

[0056] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0057] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0058] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0059] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0060] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0061] The present application provides an ink cartridge that can be detachably installed in a mounting cavity 7 of a printing device. As shown in Figures 1 and 2, the ink cartridge comprises: a cartridge body 1, a handle 2, and a chip 3.

[0062] Figures 3 to 8 show schematic diagrams of the ink cartridge from different angles. As shown in Figures 3 to 8, the cartridge body 1 is generally rectangular in shape, having a front surface c, a rear surface d, a top surface a, a bottom surface b, a left surface, and a right surface. The top surface a points in the direction opposite to gravity when the ink cartridge is installed. The front surface c, rear surface d, top surface a, bottom surface b, left surface, and right surface are interconnected to form the generally rectangular cartridge body 1 structure. The cartridge body 1 has an ink storage chamber for storing ink within.

[0063] To better illustrate the ink cartridge, a three-dimensional rectangular coordinate system (XYZ) is established, with the height of the ink cartridge defined as the Z-axis, i.e., the vertical direction of the ink cartridge; the length of the ink cartridge defined as the X-axis, i.e., the front-to-back direction of the ink cartridge; and the width of the ink cartridge defined as the Y-axis, i.e., the left-to-right direction of the ink cartridge. The direction from bottom surface b to top surface a is the +Z-axis, i.e., the upward direction; the direction from top surface a to bottom surface b is the -Z-axis, i.e., the downward direction; the direction from rear surface d to front surface c is the +X-axis, i.e., the forward direction; the direction from front surface c to rear surface d is the -X-axis, i.e., the rear direction; the direction from right surface to left surface is the +Y-axis, i.e., the left direction; and the direction from left surface to right surface is the -Y-axis, i.e., the right direction. When the Z-axis coincides with the direction of gravity, the cartridge body 1 is in the installed state, i.e., the cartridge body 1 is installed in the mounting cavity 7 in an upright position. At this point, the +X-axis also represents the installation direction of the ink cartridge, and the -X-axis also represents the removal direction of the ink cartridge.

[0064] The handle 2 is arranged on the top surface a and can rotate relative to the cartridge body 1 . The chip 3 is arranged on the top surface a and is lower than the rotation point of the handle 2 along the height direction Z of the ink cartridge.

[0065] In this embodiment, as shown in Figures 1 and 2, the handle 2 and chip 3 are both located on the top surface a of the cartridge body 1. Along the height direction Z of the ink cartridge, the chip 3 is lower than the rotation point of the handle 2. This ensures that when the ink cartridge is subjected to an external impact, the handle 2 is impacted before the chip 3, thereby making the chip 3 less susceptible to damage and reducing the cost of repairing damaged ink cartridges. Furthermore, because the handle 2 can rotate relative to the cartridge body 1, this rotation can also absorb and offset some of the impact, thereby improving the ink cartridge's impact resistance.

[0066] Specifically, as shown in Figure 2, the handle 2 has a first state and a second state, and the handle 2 can rotate relative to the box body 1 around the rotation point to switch the handle 2 between the first state and the second state; the highest point of the handle 2 when it is in the first state is higher than the highest point of the handle 2 when it is in the second state.

[0067] During the process of rotating the handle 2 from the first state to the second state, the rear end of the handle 2, that is, the end away from the rotation point, moves toward the box body 1; during the process of rotating the handle 2 from the second state to the first state, the rear end of the handle 2, that is, the end away from the rotation point, moves toward the direction away from the box body 1.

[0068] Optionally, the handle 2 is directly connected to the box body 1, and the handle 2 can switch between the first state and the second state by its own elasticity or by providing an intermediate structure such as an elastic member between the handle 2 and the box body 1. It is understood that the handle 2 can also be connected to the top surface a in a non-contact manner, that is, the handle 2 is not fixed to the top surface a.

[0069] More specifically, as shown in Figures 2, 3, and 14, the handle 2 has a protrusion 21 that extends and protrudes, and is used to contact the positioning shaft 8 in the installation cavity 7. During the process of installing the ink cartridge into the installation cavity 7, the positioning shaft 8 drives the handle 2 to change from the first state to the second state.

[0070] As the handle 2 is moved rearward, the protrusion 21 gradually protrudes from the upper surface of the handle 2. The protrusion 21 is provided with a guide surface 211 and a limiting surface 212. The guide surface 211 extends obliquely relative to the vertical and front-to-back directions. The rear end of the guide surface 211 is higher than the front end of the guide surface 211 in the vertical direction. The guide surface 211 is used to allow the positioning shaft 8 to move along it. The limiting surface 212 is inclined relative to the vertical direction. After the positioning shaft 8 moves along the guide surface 211 and separates from the guide surface 211, the positioning shaft 8 abuts against the limiting surface 212 to limit the movement of the positioning shaft 8 in the front-to-back direction.

[0071] Preferably, the limiting surface 212 is inclined relative to the upper surface of the handle 2. It is understandable that the limiting surface 212 can also be parallel to the up-down direction.

[0072] Optionally, the cross-section of the plane in which the raised portion 21 lies in the vertical and front-to-back directions approximates a triangle, a trapezoid, or an irregular trapezoid. That is, the guide surface 211 may include a single plane with the same inclination or two planes with different inclinations. When the guide surface 211 includes two planes with different inclinations, the angle between the plane closer to the limiting surface 212 and the limiting surface 212 is greater than the angle between the plane farther from the limiting surface 212 and the limiting surface 212. It is understood that the guide surface 211 may also include multiple planes with different inclinations.

[0073] During the process of installing the ink cartridge into the installation cavity 7, the handle 2 is first in the first state. After the positioning shaft 8 contacts the guide surface 211 on the protrusion 21, the positioning shaft 8 slides along the protrusion 21 and forces the handle 2 to rotate downward to the second state. After the protrusion 21 is disengaged from the positioning shaft 8, the handle 2 rotates upward and rebounds. At this time, the positioning shaft 8 contacts the limit surface 212, thereby limiting the ink cartridge from falling off from the installation cavity 7.

[0074] To remove the ink cartridge from the installation cavity 7, the operator can press the handle 2 to separate it from the positioning shaft 8, thereby releasing the positioning shaft 8 from restraining the ink cartridge. A plurality of ribs 23 are provided on the rear end of the upper surface of the handle 2. The ribs 23 slightly protrude upward, increasing the friction between the operator's fingers and the handle 2, thereby facilitating the operator's manipulation of the handle 2.

[0075] Specifically, the cross-section of the rib 23 in the plane of the vertical direction and the front-back direction is close to a semicircular or fan-shaped, so as to improve the comfort of the operator's fingers contacting the rib 23. The rib 23 can extend in the left-right direction.

[0076] Furthermore, as shown in FIG2 , a connecting portion 5 is provided on the top surface a. The connecting portion 5 is a square protrusion, which is approximately located in the middle of the upper surface in terms of width. The width of the connecting portion 5 in the left-right direction is smaller than the width of the ink cartridge. The handle 2 is connected to the top surface a through the connecting portion 5. The rotation point is located at the end of the handle 2 close to the connecting portion 5. The rotation point of the handle 2 is lower than the upper surface of the connecting portion 5. The upper surface of the connecting portion 5 is lower than the rear end of the guide surface 211 to prevent the ink cartridge from being properly installed in the installation cavity 7. The handle 2 is installed on the rear side of the connecting portion 5. Both the connecting portion 5 and the handle 2 have a certain degree of elasticity, so that the handle 2 can rotate relative to the connecting portion 5 when a force is applied, and return to the first state when no force is applied. Optionally, the interior of the connecting portion 5 is hollow to reduce the weight of the ink cartridge.

[0077] Furthermore, as shown in Figures 3 and 5, along the height direction Z of the ink cartridge, the projection of the handle 2 on the top surface a does not protrude beyond the rear surface d, that is, the handle 2 does not have a portion located behind the rear surface d of the ink cartridge. Therefore, the provision of the handle 2 will not increase the volume of the ink cartridge too much. At the same time, the rear surface d can also provide a certain degree of protection for the handle 2. When the ink cartridge is subjected to external impact or falls to the ground, the rear surface d can prevent the handle 2 from being damaged.

[0078] Optionally, as shown in Figure 2, a boss 22 is provided on the surface of the handle 2 facing the box body 1. The provision of the boss 22 can enhance the strength of the handle 2 and prevent the handle 2 from being damaged. The box body 1 has a hollow groove portion 121, and the hollow groove portion 121 is provided on the top surface a. When the handle 2 moves toward the direction close to the ink cartridge, part of the boss 2 extends into the hollow groove portion 121.

[0079] As shown in FIG2 , the empty groove portion 121 is located on the top surface a near the rear surface d. The empty groove portion 121 increases the movable space and deformation capability of the handle 2 , thereby increasing the impact resistance of the ink cartridge.

[0080] Boss 22 protrudes from the surface of handle 2 facing toward cartridge body 1. When handle 2 transitions from the first position to the second position, boss 22 moves toward cartridge body 1. The elasticity of boss 22 minimizes impact on cartridge body 1. Furthermore, the contact point between boss 22 and top surface a is relatively far from the ink reservoir, making it less likely that the impact of boss 22 on cartridge body 1 will cause ink within the reservoir to slosh. Furthermore, when the ink cartridge is installed in mounting cavity 7, recess 121 engages with the structure on the printer.

[0081] Optionally, along the rear direction, the width of the handle 2 in the left and right directions increases, so that the area where the ribs 23 and the bosses 22 are set on the handle 2 is larger in the left and right directions, so as to facilitate the setting of the ribs 23 and the bosses 22, and on the other hand, facilitate the operator to operate the handle 2.

[0082] In a specific embodiment, as shown in FIG3 , the ink cartridge has a light-shielding portion 41 fixedly arranged on the top surface a, and the light-shielding portion 41 is made of an opaque material; along the height direction Z of the ink cartridge, the highest point of the handle 2 is higher than the light-shielding portion 41, and at least a portion of the light-shielding portion 41 is higher than the chip 3. When the ink cartridge is subjected to external impact, the handle 2 can protect the light-shielding portion 41 and the chip 3 from damage.

[0083] Furthermore, the upper surface of the light shielding portion 41 is flush with the upper surface of the connecting portion 5. When the ink cartridge is subjected to an external impact, the connecting portion 5 resists the impact before the light shielding portion 41, preventing the light shielding portion 41 from being damaged before the connecting portion 5. Since the ink cartridge can still be recognized and ink can still be supplied normally when installed in the installation cavity 7 even if only the connecting portion 5 is damaged, the ink cartridge's impact resistance is improved.

[0084] Furthermore, the width of the connecting portion 5 in the left-right direction is greater than the width of the light shielding portion 41 in the left-right direction, thereby increasing the protective effect of the connecting portion 5 on the light shielding portion 41. The width of the connecting portion 5 in the left-right direction is greater than the width of the connection between the handle 2 and the connecting portion 5 in the left-right direction, thereby reducing the resistance and difficulty of rotating the handle 2 relative to the connecting portion 5.

[0085] In this embodiment, as shown in FIG3 , the chip 3, light shielding portion 41, connecting portion 5, and handle 2 are sequentially arranged on top surface a along the direction from front surface c to rear surface d. Top surface a has at least three regions of varying heights. The chip 3 and light shielding portion 41 are arranged in the lowest region of top surface a, so that the chip 3 and light shielding portion 41 are least impacted when the ink cartridge is impacted. That is, the chip 3 and light shielding portion 41 are arranged in regions of the top surface a at the same height. The connecting portion 5 is arranged in the highest region of top surface a, and the handle 2 is connected to the connecting portion 5, so that the connecting portion 5 and handle 2 are most impacted when the ink cartridge is impacted. That is, the region of top surface a where the connecting portion 5 and handle 2 are located is higher than the region of top surface a where the chip 3 and light shielding portion 41 are located. The recess 121 is arranged in a region of intermediate height on top surface a to avoid the protrusion 22 on the handle 2.

[0086] Along the height direction Z of the ink cartridge, the highest point of the handle 2 when in the first state is higher than the light-shielding portion 41, and at least part of the light-shielding portion 41 is higher than the chip 3. Therefore, when the ink cartridge is subjected to external impact and the handle 2 is damaged, the light-shielding portion 41 can continue to absorb and offset part of the impact, thereby reducing the probability of damage to the chip 3, and thereby reducing the maintenance cost when the ink cartridge is damaged.

[0087] Specifically, a light emitter and a light receiver are disposed within the installation cavity 7. The light emitter can emit light, and the light receiver can receive light. When the ink cartridge is installed in the installation cavity 7, the light shielding portion 41 blocks the light emitted by the light emitter, preventing the light from being received by the light receiver. The printer generates light signals of varying intensities, allowing the printer to detect the installation status of the ink cartridge.

[0088] In the prior art, the installation detection unit on the ink cartridge is equipped with a float that changes its light-shielding state based on the remaining ink level in the ink reservoir. During installation, if the user shakes the ink cartridge, the ink inside the cartridge will slosh, causing the float to move with the ink. This repeated forward and backward movement of the float can affect the accuracy of the ink cartridge installation detection.

[0089] In this application, the light-shielding portion 41 is fixedly arranged on the top surface a, and the light-shielding portion 41 will not move with the consumption and shaking of ink in the ink storage chamber. Therefore, the ink cartridge installation status detected by the printer and the light-shielding portion 41 is more accurate, thereby improving the accuracy of the ink cartridge installation detection.

[0090] Furthermore, as shown in FIG3 and FIG13 , two light shielding portions 41 are provided, and a light-transmitting area 42 is formed between the two light shielding portions 41 .

[0091] The light emitted by the light emitter can pass through the light-transmitting area 42. Since the light-transmitting area 42 is located between the two light-shielding portions 41, when the ink cartridge is installed into the installation cavity 7, the light receiver first does not receive light for a short period of time, then receives light for a short period of time, and finally does not receive light for a long period of time, indicating that the ink cartridge is properly installed.

[0092] Optionally, as shown in FIG3 , the two light-shielding portions 41 are two light-shielding areas on the same raised structure, i.e., at least the portions of the two light-shielding portions 41 near the top surface a are connected. The light-transmitting area 42 is a depression between the two light-shielding portions 41. In the vertical direction, the lowest point of the light-transmitting area 42 is lower than the lowest point of the connecting portion 5 to ensure accurate ink cartridge installation detection.

[0093] Optionally, as shown in FIG. 13 , the two light shielding portions 41 are two light shielding plates that independently protrude from the top surface a, that is, there is no portion connected to each other between the two light shielding portions 41 .

[0094] Optionally, the light-transmitting area 42 may be made of a light-transmitting material.

[0095] In a specific embodiment, as shown in Figure 9, the box body 1 includes a main body 11 and a cover 12, the cover 12 is sleeved on the outside of the main body 11, the main body 11 is provided with an ink storage cavity, the cover 12 is provided with a top surface a, and the top surface a is provided with a chip 3, a handle 2 and a light-shielding portion 41.

[0096] In this embodiment, as shown in FIG9 , for different printers, the shapes of the ink cartridges adapted thereto may be slightly different. By uniformly producing the main body 11 and assembling the cover 12 adapted to different printer devices on the main body 11, the production cost of the ink cartridge can be reduced.

[0097] Specifically, as shown in Figures 10 and 11, a snap-fitting column 122 is provided on the side of the cover 12 that is in contact with the body 11, and a snap-fitting groove 111 is provided on the body 11. The snap-fitting column 122 can extend into the snap-fitting groove 111 to achieve the snap connection between the body 11 and the cover 12, making it difficult for the body 11 and the cover 12 to be separated.

[0098] Optionally, a plurality of clamping posts 122 are provided, and the plurality of clamping posts 122 are evenly or unevenly arranged along the circumference of the cover 12. To match the clamping slots 111 with the clamping posts 122, the number and arrangement positions of the clamping slots 111 correspond to those of the clamping posts 122.

[0099] Furthermore, only the structure for storing and supplying ink is provided on the main body 11, and other functional structures for realizing ink cartridge installation detection and signal detection are provided on the cover 12, thereby improving the adaptability of the main body 11 to a greater extent.

[0100] As shown in Figure 14 , the ink cartridge also includes an ink nozzle 6 and an ink needle within the mounting cavity 7. The ink nozzle 6 communicates with the ink reservoir. When the ink cartridge is installed within the mounting cavity, the ink needle inserts into the ink nozzle 6, allowing the ink within the ink reservoir to be supplied to the printer. A seal is provided within the ink nozzle 6 to prevent ink within the ink reservoir from leaking through the ink nozzle 6. The seal can be a self-sealing valve or a movable valve core coupled with an elastic member such as a spring.

[0101] Specifically, the ink nozzle 6 is provided on the front surface c of the cartridge body 1 , and along the height direction Z of the ink cartridge, the ink nozzle 6 is located below the chip 3 and the handle 2 .

[0102] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
