The present invention will be described in further detail with reference to the accompanying drawings, in order to better describe an ink cartridge, reference is made to the concept of X, Y, Z axes, three mutually orthogonal spatial axes are taken as X, Y and Z axes, as shown in fig. 1 to 11 coordinate axes, the X axis direction is defined as the length direction of the cartridge body 1, wherein the + X axis is the insertion installation direction of the ink cartridge along the length direction; the Y-axis direction is defined as the width direction of the box body 1, wherein the + Y-axis is the left side of the left-right direction of the box body 1, the-Y-axis is the right side of the left-right direction of the box body 1, the Z-axis is defined as the up-down direction of the box body 1, wherein the + Z-axis is the upward direction of the box body 1, and the-Z-axis is the downward direction of the box body 1. The movement in the back-and-forth or up-and-down direction or the movement in the X-axis, Y-axis, and Z-axis directions in the embodiments are not limited to the movement in the vertical, horizontal, or parallel direction, and the movement having an inclination angle may be calculated as long as there is a component movement in the direction.

Example one

An ink cartridge, as shown in fig. 1 and 2, for mounting in an insertion direction into a cartridge attachment unit 4 of a printer, a mounting portion 41 being provided in the cartridge attachment unit 4, the mounting portion 41 being a cylindrical long rod in this embodiment;

as shown in fig. 1 to 6, an ink cartridge includes:

a case 1 having an upper surface 101, a front surface 102, and a rear surface 103;

a front surface 102, the front surface 102 facing in an insertion direction of the cartridge when the cartridge 1 is inserted into the mounting portion 41;

the rear surface 103 is located on the side of the case 1 away from the front surface 102 (i.e., -X-axis direction);

an upper surface 101 located at an upper side (i.e., + Z-axis direction) of the case 1 between the front surface 102 and the rear surface 103;

a storage medium 2 provided on an upper surface 101 of the cartridge body 1, storing variable ink amount information readable by a printer, and having at least one electrical contact face 21 electrically contactable with the contact pins 42 in the cartridge attachment unit 4; in the present embodiment, a part of the storage medium 2 is housed and disposed in the case 1.

A lock portion 3 provided on an upper surface 101 of the cartridge body 1, having a coupling surface 31, the coupling surface 31 being configured to be capable of resisting a biasing force from the mounting portion 41 to keep a kind of ink cartridge mounted in the printer; it can be seen that the bonding surface 31 and the at least one electrical contact surface 21 are disposed on the upper surface 101 of the case 1. When the cartridge 1 is mounted to the mounting portion 41, the electrical junction face 21 is closer to the front surface 102 than the joining surface 31.

The combination surface 31 is parallel to the at least one electrical connection surface 21 and is obliquely arranged with the length direction of the box body 1, and the combination surface 31 is obliquely arranged on the upper surface 101 of the box body 1.

Preferably, the ink cartridge further comprises:

an ink reservoir (not shown) provided in the cartridge body 1 between the front surface 102 and the rear surface 103, and configured to be capable of storing ink; the upper surface 101 is located above the ink reservoir.

The ink outlet 14, which is provided at the front surface 102 of the cartridge body 1 along the longitudinal direction thereof and below the storage medium 2, faces in the insertion direction of the ink cartridge (i.e., + X axis direction), is configured to be able to supply ink from the inside of the ink reservoir to the printer.

In the present embodiment, when the cartridge body 1 is mounted to the mounting portion 41, the ink outlet 14 is located on the side of the electrical contact surface 21 away from the contact pins 42 in the cartridge attachment unit 4.

Preferably, as shown in fig. 6, the ink outlet 14 has an elastic member 141 and a valve therein, and when the cartridge 1 is mounted to the mounting portion 41, the elastic member 141 can generate a biasing force to keep the ink cartridge in the printer; specifically, one end of the elastic member 141 abuts against the case 1, and the other end of the elastic member 141 abuts against the mounting portion 41. When the ink cartridge is loaded into the cartridge attachment unit 4 from below the mounting portion 41, the ink cartridge may slightly rotate in the counterclockwise direction due to the elastic force of the elastic member 141, so that the electrical contact surface 21 is brought into contact with the contact pin 42, thereby preventing the electrical contact surface 21 from being worn due to excessive force at the moment when the electrical contact surface 21 is brought into contact with the contact pin 42.

When the ink cartridge is taken out from the cartridge attachment unit 4, the ink cartridge is in the first posture or the second posture; the first posture and the second posture refer to the inclined position state of the ink cartridge within the cartridge attachment unit 4.

As shown in fig. 12 and 13, when the ink cartridge is in the first posture, at least part of the joint surface 31 is located above the mounting portion 41 (i.e., in the + Z direction); or all of the bonding surfaces 31 are located in the + Z direction of the mounting portion 41.

As shown in fig. 14 and 15, when the ink cartridge is in the second posture, the joint surface 31 is located below the mounting portion 41 (i.e., -Z direction).

As shown in fig. 4 and 5, the facing direction of the electrical contact surface 21 is opposite to the facing direction of the bonding surface 31, that is, the electrical contact surface 21 is inclined obliquely upward in the-X, + Z-axis direction from the side of the electrical contact surface 21 on the + X axis; also, the bonding surface 31 is parallel to the electrical contact surface 21, i.e., the bonding surface 31 is inclined in the-X, + Z direction from the side of the bonding surface 31 on the + X axis. This embodiment provides a specific tilted orientation of the electrical contact surface 21.

A shielding portion 15 provided to the cartridge body 1, which attenuates or absorbs light emitted from the optical sensor in the cartridge attachment unit 4; along the longitudinal direction of the cartridge body 1, the shielding portion 15 is located between the storage medium 2 and the locking portion 3. The shielding portion 15 is located in front of the bonding surface 31 in the direction of the ink outlet 14.

Advantageous effects

The mounting portion 41 in the cartridge attachment unit 4 can apply a biasing force to the engagement surface 31, but since the engagement surface 31 and the electrical contact surface 21 in this embodiment are parallel to each other and arranged obliquely to the longitudinal direction of the cartridge body 1, and the longitudinal direction of the cartridge body 1 intersects with the insertion direction portion of the ink cartridge, when the ink cartridge is mounted in the cartridge attachment unit 4 of the printer, the mounting portion 41 in the cartridge attachment unit 4 can apply a force to the engagement surface 31 and simultaneously can also act on the storage medium 2 to contact the contact pins 42 in the cartridge attachment unit 4, so that the electrical contact surface 21 and the contact pins 42 can be stably connected, thereby ensuring that the printer can stably perform a printing operation.

When the ink cartridge is mounted in place, the elastic member 141 on the ink outlet 14 imparts a slight rotational force to the ink cartridge, the mounting portion 41 applies an upward force to the coupling surface 31 in a direction perpendicular to the coupling surface 31, the mounting portion 41 biases the storage medium 2 in the same direction because the coupling surface 31 is parallel to the electrical contact surface 21, and the electrical contact surface 21 is parallel to the coupling surface 31 and contacts the contact pin 42 in a direction perpendicular to the surface of the electrical contact surface 21, so that the biasing force can maximally bring the electrical contact surface 21 into contact with the contact pin 42 to increase the tightness of the contact between the electrical contact surface 21 and the contact pin 42. And since the joining surface 31 is provided obliquely, when an ink cartridge is mounted in the cartridge attaching unit 4 in the printer, even if the printer is shaken by an external force, the ink cartridge is not easily detached from the cartridge attaching unit 4.

Example two

As shown in fig. 7 to 11, the difference between the second embodiment and the first embodiment is: the orientation direction of the electrical contact surface 21, the orientation direction of the bonding surface 31, and the arrangement of the storage medium 2 on the case 1.

As shown in fig. 8 and 9, in the present embodiment, the facing direction of the electrical connection surface 21 is the same as the facing direction of the bonding surface 31, that is, the electrical connection surface 21 is inclined obliquely downward in the-X, -Z axis directions from the side of the electrical connection surface 21 on the + X axis; furthermore, the bonding surface 31 is parallel to the electrical connection surface 21, i.e., the bonding surface 31 is inclined obliquely downward toward the-X and-Z axes from the side of the bonding surface 31 on the + X axis, so that it can be seen that this embodiment provides another specific inclination orientation of the electrical connection surface 21.

The upper surface 101 of the box body 1 is provided with a first mounting groove 11 for mounting the storage medium 2;

an ink box comprises a storage mounting body 13, a first mounting groove 11, a second mounting groove 12 and a storage mounting body, wherein the storage mounting body is arranged on a box body 1 and is provided with the second mounting groove 12;

The scheme provides a specific implementation mode that the storage medium 2 is arranged on the box body 1.

The storage medium 2 is detachably disposed in the first mounting recess 11 and the second mounting recess 12, which facilitates the mounting and dismounting of the storage medium 2, and the combination structure of the first mounting recess 11 and the second mounting recess 12 enables the storage medium 2 to be stably disposed on the case 1, and the plug-in mounting enables the contact between the electrical contact surface 21 and the contact pin 42 to be more stable.

The second mounting recess 12 has a mounting inclined surface 121, and the mounting inclined surface 121 is parallel to the inclined direction of the electrical contact surface 21, so that the storage medium 2 can be attached to the mounting inclined surface 121 when the storage medium 2 is inserted into and mounted in the second mounting recess 12. The scheme provides a specific implementation mode that the existing storage medium 2 and the length direction of the box body 1 are arranged in an inclined mode, so that the scheme can be matched with the existing storage medium 2, and the structural structure of the storage medium 2 does not need to be changed.

As shown in fig. 8 and 11, a card slot 131 is formed in the second mounting groove 12, a card portion 22 is formed on the storage medium 2, and the card portion 22 is clamped in the card slot 131. In the present embodiment, the card slot 131 is triangular, and the card portion 22 is a triangular protrusion matching with the card slot 131, so that the storage medium 2 can be stably clamped on the storage mounting body 13.

The second mounting recess 12 is provided therein with a plurality of receiving portions 122, and the storage medium 2 abuts against the receiving portions 122.
