Referring to fig. 1 to 17, the present embodiment provides an ink cartridge 10 applied to a printer 20, the printer 20 is provided with a contact pin 210, the ink cartridge 10 includes an ink cartridge body 11, a chip 12 and a chip holder 13, the chip 12 is fixed on the chip holder 13; when the ink cartridge 10 is mounted on the printer 20 along the mounting direction X, the printer 20 may drive the chip fixing seat 13 to linearly move along the top surface of the ink cartridge body, before the chip fixing seat linearly moves, the chip fixing seat is in a first position, and after the chip fixing seat linearly moves, the chip fixing seat is in a second position; the chip in the first position is closer to the top surface of the ink cartridge body than the chip in the second position, and when the chip fixing seat is in the second position, the chip abuts on the contact pins.

Specifically, the printer 20 may be an ink jet printer, and the ink cartridge 10 is connected to the printer 20 for supplying ink to the printer 20. The ink cartridge 10 includes a cartridge body 11, and a container-like structure for containing ink, such as an ink bag, is disposed in the cartridge body 11, or a sealed cavity is directly formed inside the cartridge body 11. The container-like structure is provided with an ink outlet 114, the ink outlet 114 is communicated with an ink supply part (not shown) of the printer 20, and a print head (not shown) on the printer 20 is connected with the ink supply part. Thus, ink can be delivered to the printhead through the ink outlet 114 and the ink supply to enable the printer 20 to print predetermined text or images.

The ink cartridge body 11 is further provided with an air port 115 for adjusting the internal pressure of the ink cartridge body 11 so that ink can be discharged through the ink outlet 114.

The ink cartridge body 11 is further provided with a chip 12 and a chip fixing seat 13, and the chip 12 is clamped and fixed on the chip fixing seat 13. The printer 20 is further provided with a stylus 210, and the structure of the stylus 210 may be well known to those skilled in the art, for example, the stylus 210 may be an elastic member. The chip 12 is provided with an electrical connection portion, and when the electrical connection portion is in contact with the contact pins 210, the chip 12 is electrically connected to the contact pins 210, and communication between the chip 12 and the printer 20 is possible.

The chip fixing base 13 is movably connected to the ink cartridge body 11, for example, the chip fixing base 13 is connected to the ink cartridge body 11 in a sliding or rotating manner. In this embodiment, the chip fixing seat 13 can linearly move along the top surface of the ink cartridge body 11, so that the chip fixing seat 13 extends out of the ink cartridge body 11, i.e., the chip 12 is driven to extend out of the ink cartridge body 11, at this time, the distance between the chip 12 and the ink cartridge body 11 is increased, and the distance between the chip 12 and the contact pins 210 is decreased.

That is, before the chip holder 13 moves linearly relative to the cartridge body 11, the chip holder is in the first position; after the linear movement of the chip holder 13 relative to the ink cartridge body 11, the chip holder is in the second position, and the chip in the second position is closer to the contact pins than the chip in the first position, so as to electrically connect the chip and the contact pins.

The linear moving manner of the chip fixing base 13 relative to the ink cartridge body 11 may be different according to the top surface structure of the ink cartridge body 11. For example, when the position of the cartridge body 11 in contact with the chip holder 13 is a plane, the linear movement of the chip holder 13 relative to the cartridge body 11 is a translation along the plane.

The linear movement distance of the chip holder 13 can be set according to the position of the contact pin 210 on the printer 20, and this embodiment is not limited thereto.

When the ink cartridge 10 is installed on the printer 20, the printer 20 drives the chip fixing seat 13 to linearly move relative to the ink cartridge body 11, the distance between one end of the chip 12 fixed on the chip fixing seat 13 and the contact pin 210 becomes smaller, namely, the distance between the chip 12 and the contact pin 210 becomes smaller until the electric connection part of the chip 12 abuts against the contact pin 210 of the contact pin 210, the chip 12 is electrically connected with the contact pin 20, at this time, the ink cartridge 10 is installed on the printer 20, and the ink cartridge 10 and the printer 20 are relatively fixed.

That is to say, at this moment, chip fixing base 13 sets up between ink horn body 11 and printer 20, and chip fixing base 13 realizes fixedly through the assembly cooperation between ink horn body 11 and the printer 20, because the connection between ink horn body 11 and the printer 20 is comparatively firm, as long as ink horn body 11 does not take place relative movement with printer 20, for example ink horn body 11 dismantles from printer 20, chip fixing base 13 just can be firm support between ink horn body 11 and printer 20, that is to say that the electric connection between chip 12 and contact pin 210 is comparatively firm.

In some alternative embodiments, when the top surface of the ink cartridge body 11 has an uneven top surface, the linear movement of the chip holder 13 relative to the ink cartridge body 11 may be a combination of translation and rotation, so that the chip may protrude toward one side of the contact pin. Specifically, the method comprises the following steps. One of the chip fixing seat 13 and the ink cartridge body 11 is provided with a sliding part 131, the other of the chip fixing seat 13 and the ink cartridge body 11 is provided with a guiding part 111, the guiding part 111 extends along the moving direction Y of the chip fixing seat 13, the sliding part 131 is inserted into the guiding part 111 and can move relative to the guiding part 111, and the chip fixing seat 13 can also rotate relative to the ink cartridge body 11 around the extending direction of the sliding part 131.

The sliding portion 131 can move relative to the guiding portion 111 along the extending direction of the guiding portion 111, and thus the relative translation between the chip fixing seat 13 and the ink cartridge body 11 is realized. And the chip fixing seat 13 can also rotate by taking the extending direction of the sliding part 131 as an axis, so that one end of the chip fixing seat 13 moves linearly towards one side close to the ink box body 11, and the other end of the chip fixing seat 13, which is provided with the chip 12, moves linearly towards one side far away from the ink box body 11, so as to reduce the distance between the chip 12 and the contact pin 210.

The moving direction Y of the chip holder 13 may be set at an angle to the mounting direction X of the ink cartridge 10 according to the set position and orientation of the contact pins 210. Alternatively, the extending direction of the guide portion 111 is arranged in parallel with the mounting direction X of the ink cartridge 10; when the ink cartridge 10 is mounted on the printer 20, the chip holder 13 is movable relative to the cartridge body 11 in the direction opposite to the mounting direction X of the ink cartridge 10, and the structure is simple.

And the extending direction of the sliding portion 131 is perpendicular to the extending direction of the guide portion 111. Thus, when the chip holder 13 rotates around the extending direction of the sliding portion 131, one end of the chip holder 13 rotates toward the side close to the ink cartridge body 11, and the other end of the chip holder 13, at which the chip 12 is disposed, rotates toward the side away from the ink cartridge body 11, so as to reduce the distance between the chip 12 and the contact pins 210.

The sliding part 131 may be disposed on the cartridge body 11, and the guiding part 111 may be disposed on the chip holder 13. In consideration of the small size of the chip holder 13, the sliding part 131 may be disposed on the chip holder 13, and the guiding part 111 may be disposed on the cartridge body 11, which is easy to machine.

The sliding portion 131 and the guide portion 111 may have different structures. Illustratively, the sliding portion 131 is hinged to the chip holder 13, and the guiding portion 111 is a guiding protrusion or a guiding groove or the like connected to the sliding portion 131.

In some alternative embodiments, the guiding portion 111 is a guiding sliding slot disposed on the ink cartridge body 11, and the sliding portion 131 is a cylindrical structure disposed on the chip fixing seat 13; the sliding part 131 is inserted into the guide chute and can move relative to the guide chute. At this time, the sliding part 131 is convexly arranged on the chip fixing seat 13, and the guide sliding groove is arranged on the ink box body 11, so that the structure is simple, and the forming is easy.

The width of the guide chute may be the same as the outer diameter of the cylindrical structure, so that the inner wall of the guide chute faces the sliding portion 131 to form a limit, thereby preventing the sliding portion 131 from jumping in the width direction of the guide portion 111, and the chip fixing seat 13 has high movement stability.

The chip fixing base 13 can be driven by the printer 20 to rotate relative to the ink box body 11. For example, the printer 20 is provided with a butting portion, and when the chip fixing seat 13 abuts against the end face of the butting portion, the chip fixing seat 13 can obtain a driving force towards a direction away from the ink cartridge body 11 to drive the chip fixing seat 13 to rotate.

In some alternative embodiments, the ink cartridge body 11 is provided with a driving portion 112 protruding out of the ink cartridge body 11, the driving portion 112 protrudes towards the contact pins 210, and the driving portion 112 is located on a side of the chip fixing base 13 facing away from the contact pins 210; and the driving part 112 is disposed on the moving track of the chip fixing seat 13, and the chip fixing seat 13 can contact with the driving part 112, so that the chip fixing seat 13 rotates around the sliding part 131 while moving along the wall surface of the driving part 112 relative to the driving part 112, and changes the distance between the chip 12 and the ink box body 11.

The driving portion 112 protrudes out of the wall surface of the ink cartridge body 11, and the wall surface of the driving portion 112 at least includes a smooth curved surface, so that when the chip fixing seat 13 contacts with the driving portion 112 and moves relative to the driving portion 112 along the wall surface of the driving portion 112, the moving process of the chip fixing seat 13 is stable.

The driving portion 112 may be a columnar protrusion or a spherical protrusion, and when the driving portion 112 is a columnar protrusion, the cross-sectional shape of the driving portion 112 may be an irregular curved shape, which is not limited in this embodiment.

The distribution length of the smooth curved surface along the extending direction of the guide portion 111 may be different according to the contact track length of the chip holder 13 and the driving portion 112. For example, in the present embodiment, the smooth curved surface may cover the driving portion 112 along the extending direction of the guiding portion 111, and at this time, the wall surface of the driving portion 112 is smoothly connected with the cartridge body 11.

The driving portion 112 is located at the end of the chip fixing base 13 where the chip 12 is located, so that when the end of the chip fixing base 13 where the chip 12 is located contacts with different positions of the driving portion 112, the distance between the chip 12 and the ink cartridge body 11 is correspondingly increased or decreased, that is, the distance between the chip 12 and the contact pins 210 is correspondingly increased or decreased, and at this time, the chip fixing base 13 rotates with the sliding portion 131 as an axis.

Illustratively, when the chip holder 13 contacts the top end of the driving part 112, the distance between the chip 12 and the cartridge body 11 is maximized, and the chip 12 is electrically connected to the contact pins 210. At this time, one side surface of the chip holder 13 is pressed against the driving portion 112, the chip 12 on the chip holder 13 is pressed against the contact pins 210, and the connection between the chip 12 and the contact pins 210 is relatively firm.

The driving portion 112 may be disposed at different positions according to the relative moving direction Y of the chip holder 13 and the ink cartridge body 11, for example, when the moving direction Y of the chip holder 13 is the same as the mounting direction X, the driving portion 112 may be disposed at one side of the chip holder 13, and the chip holder 13 moves toward one side close to or away from the driving portion 112 during the moving process relative to the ink cartridge body 11.

When the moving direction Y of the chip holder 13 is opposite to the mounting direction X of the ink cartridge 10, in some alternative embodiments, the chip holder 13 is provided with an accommodating groove 132 for accommodating the driving portion 112, and the contour of the accommodating groove 132 is matched with the contour of the driving portion 112, or the extension length of the accommodating groove 132 along the moving direction Y of the chip holder 13 is greater than the extension length of the driving portion 112 along the moving direction Y of the chip holder 13.

That is, when the ink cartridge 10 is not mounted on the printer 20, the driving part 112 is located in the receiving recess 132 of the chip holder 13.

In the process of installing the ink cartridge 10 in the printer 20, the printer 20 drives the chip fixing seat 13 to move, the sliding part 131 moves towards one side far away from the driving part 112, and when the side surface of the chip fixing seat 13 facing the ink cartridge body 11 contacts with the wall surface of the driving part 112, the distance between one end of the chip fixing seat 13, which is provided with the chip 12, and the ink cartridge body 11 is increased, namely, the chip fixing seat 13 rotates around the sliding part 131 while moving until the chip 12 is electrically connected with the contact pins 210.

When the contour of the receiving groove 132 matches the contour of the driving portion 112, the chip holder 13 rotates around the sliding portion 131 while moving along the guiding portion 111. When the extension length of the receiving groove 132 along the moving direction Y of the chip holder 13 is greater than the extension length of the driving portion 112 along the moving direction Y of the chip holder 13, the chip 12 fixing member may first move along the guiding portion 111 relative to the ink cartridge body 11, and then the side of the chip holder 13 facing the ink cartridge body 11 contacts with the wall surface of the driving portion 112, and at this time, the chip holder 13 rotates around the sliding portion 131 while moving along the guiding portion 111, which is determined according to the moving stroke of the chip holder 13 along the guiding portion 111.

Referring to fig. 8 to 13, in some alternative embodiments, the extension length of the guide portion 111 is the same as the moving stroke of the chip holder 13, so that the sliding portion 131 abuts against the end of the guide portion 111 when the chip 12 is electrically connected to the contact pins 210.

That is, when the ink cartridge 10 is mounted on the printer 20, the sliding portion 131 moves to the end of the guide portion 111 and abuts against the end of the guide portion 111.

At this time, the side of the chip holder 13 facing the cartridge body 11 abuts against the driving part 112, the chip 12 is provided on the side opposite to the chip holder 13, and the chip 12 abuts against the contact pins 210; one end of the chip holder 13 in the mounting direction X abuts against the printer 20, and the sliding portion 131 of the chip holder 13 abuts against the end of the guide portion 111. In this way, the chip holder 13 is firmly clamped between the ink cartridge body 11 and the printer 20 by the fitting relationship between the ink cartridge body 11 and the printer 20, so that the connection between the chip 12 and the contact pins 210 is stable.

In some alternative embodiments, an elastic reset piece 14 is arranged between the chip fixing seat 13 and the ink box body 11, and the elastic force of the elastic reset piece 14 is parallel to and opposite to the moving direction Y of the chip fixing seat 13; when the ink cartridge 10 is separated from the printer 20, the chip fixing seat 13 may move along the extending direction of the guiding portion 111 under the elastic force of the elastic restoring member 14 to reduce the distance between the chip 12 and the ink cartridge body 11.

In this way, when the ink cartridge 10 is detached from the printer 20, for example, when the ink cartridge 10 is repaired, the chip fixing seat 13 can move under the elastic force of the elastic member, the side surface of the chip fixing seat 13 facing the ink cartridge body 11 moves relative to the driving portion 112, and the distance between the end of the chip fixing seat 13 where the chip 12 is disposed and the ink cartridge body 11 decreases until the driving portion 112 is accommodated in the accommodating recess 132. Thus, the distance between the chip 12 and the ink box body 11 is small, the chip 12 can be protected, and the probability that foreign objects impact the chip 12 is reduced.

The elastic return member 14 may be a spring, an elastic rubber block, or the like.

The printer 20 can abut against any position of the chip holder 13 depending on the structure of the chip holder 13 and the structure of the printer 20. Considering that the moving direction Y of the chip holder 13 is set opposite to the mounting direction X of the ink cartridge 10, alternatively, the position of the chip holder 13 abutting against the printer 20 is located at the end of the chip holder 13 in the moving direction Y itself; and/or, the positions of the chip fixing seat 13 abutting against the printer 20 are located on both sides of the chip fixing seat 13 along the self-moving direction Y.

The position of the chip fixing base 13 abutting against the printer 20 may be a contact surface, so that the contact area between the chip fixing base 13 and the printer 20 is large, and the contact between the chip fixing base 13 and the printer 20 is stable. The contact surface may be an end surface of the chip holder 13 in the mounting direction X (as shown in fig. 8 to 13). Of course, the contact surface may be disposed on any one side or both sides of the chip holder 13 in the mounting direction X (as shown in fig. 14 to 17), and the present embodiment is not limited thereto.

In some alternative embodiments, the ink cartridge body 11 is further provided with a light shielding portion 15, and the light shielding portion 15 is used for shielding detection light of the printer 20 when the ink cartridge 10 is installed on the printer 20, so as to prompt that the ink cartridge 10 is installed in place.

That is, when the ink cartridge 10 is installed on the printer 20, the light blocking portion 15 on the ink cartridge body 11 can block or reflect the detection light of the printer 20, and the control system of the printer 20 receives the signal indicating that the detection light is blocked or reflected, and determines that the ink cartridge 10 is installed in place, that is, the ink cartridge 10 is stably connected to the printer 20.

The ink cartridges 10 may have different kinds, for example, different colors or different kinds of inks may be disposed in the ink cartridges 10, so as to facilitate the printer 20 to recognize and distinguish the kinds of the ink cartridges 10, in some alternative embodiments, the light shielding portions 15 may be disposed at different positions of the ink cartridge body 11 along the light emitting direction of the detection light, so as to distinguish the kinds of the ink cartridges 10 by changing the light emitting distance of the detection light.

Thus, when the light-shielding portion 15 is disposed at different positions along the light-emitting direction of the detection light, the distance between the part of the printer 20 emitting the detection light and the light-shielding portion 15 changes, that is, the light-emitting distance of the detection light changes, and the control system of the printer 20 can identify the type of the ink cartridge 10 according to the light-emitting distance of the detection light.

The light shielding portion 15 may be fixedly connected to the cartridge body 11.

In some alternative embodiments, the cartridge body has an ink outlet; in the mounting direction of the ink box, the chip and the chip fixing seat are farther away from the ink outlet relative to the shading part; in the first position, the highest point of the chip is lower than the light shielding part in the gravity direction; in the second position, the highest point of the chip is higher than the light shielding portion in the gravity direction.

The relative position relationship of the ink outlet, the shading part and the chip fixing seat on the ink box body can be set as required, and the embodiment is not limited.

When the shading part is fixed on the ink box body, the shading part protrudes out of the outer wall surface of the ink box body. When the chip fixing seat is located at the first position, the highest point of the chip is higher than the shading part in the gravity direction, so that the shading part can protect the chip. For example, when the foreign object collides with the ink box body, the foreign object can stop striking the shading part, and the chip is prevented from being struck by the foreign object.

When the ink cartridge is mounted on the printer, the chip protrudes toward one side of the contact pins, and the protruding distance of the chip in the direction of gravity may be set according to the assembly structure of the ink cartridge and the printer, for example, when the chip is electrically connected to the contact pins, the highest point of the chip is higher than the light shielding portion in the direction of gravity.

It should be noted that the light shielding portion 15 may be movably connected to the cartridge body 11. In some alternative embodiments, the protection accommodating groove 113 is formed in the ink cartridge body 11, and the light shielding portion 15 can be accommodated in the protection accommodating groove 113.

Thus, in the event of an external force impact, the light shielding portion 15 can move into the protective accommodating groove 113 by itself, and at this time, the light shielding portion 15 does not protrude from the outer wall surface of the cartridge body 11, thereby protecting the light shielding portion 15 and preventing the light shielding portion 15 from being deformed or broken due to the external force impact.

When the protection accommodating groove 113 is formed on the ink cartridge body 11, in order to facilitate identification of the type of the ink cartridge 10, in some alternative embodiments, the protection accommodating groove 113 has a plurality of access ports 1131, and the access ports 1131 are used for allowing the light shielding portion 15 to extend out of the protection accommodating groove 113; the plurality of entrances and exits 1131 are provided at intervals along the light emitting direction of the detection light, and the light shielding portions 15 can be extended through different entrances and exits 1131 to distinguish the types of ink cartridges 10 by changing the light emitting distance of the detection light.

In this case, the cartridge body 11 may be provided with a plurality of light-shielding portions 15, and the light-shielding portions 15 may correspond to the access 1131 so that one of the light-shielding portions 15 is selected according to the type of the ink cartridge 10 and extends out of the protection storage groove 113 through the access 1131.

Of course, the cartridge body 11 may be provided with one light shielding portion 15, so that the light shielding portion 15 is provided at the corresponding position of the access 1131 according to the type of the ink cartridge 10.

Thus, when the light-shielding portion 15 extends out of the protective accommodating groove 113 from a different access 1131, the distance between the component of the printer 20 emitting the detection light and the light-shielding portion 15 changes, that is, the light-emitting distance of the detection light changes, and the control system of the printer 20 can identify the type of the current ink cartridge 10 according to the light-emitting distance of the detection light.

When the light shielding portion 15 is movably connected to the ink cartridge body 11, the light shielding portion 15 may have different structures to be received in or extended out of the protection receiving groove 113. Illustratively, the light shielding portion 15 may be slidably connected to the cartridge body 11.

In some alternative embodiments, the ink cartridge 10 includes the light shielding member 16, the light shielding member 16 is rotatably connected to the ink cartridge body 11, the light shielding member 16 includes a weight portion 161 and a light shielding portion 15, the weight portion 161 and the light shielding portion 15 are respectively disposed at two sides of a rotation axis of the light shielding member 16, and the rotation axis of the light shielding member 16 and the weight portion 161 are both located in the protection accommodating groove 113; the weight 161 is higher than the weight of the light shielding portion 15 so that the light shielding portion 15 protrudes out of the protection accommodating groove 113; and the light shielding portion 15 can also rotate around the rotation axis of the light shielding member 16 to be received in the protection receiving groove 113.

In this way, in the natural state, the weight 161 is located below the light shielding portion 15 in the height direction, and the light shielding portion 15 protrudes out of the protection accommodating groove 113.

When the light shielding part 15 is collided or impacted by an external object, the light shielding member 16 can rotate around its own rotation axis, the light shielding part 15 rotates into the protection accommodating groove 113, and at this time, the counterweight part 161 rotates upwards around the rotation axis of the light shielding member 16 and still stays in the protection accommodating groove 113, that is, at this time, the light shielding member 16 is entirely located in the protection accommodating groove 113.

When the external object is separated from the light shielding portion 15 or the ink cartridge body 11, the weight portion 161 rotates around the rotation shaft of the light shielding member 16 under the action of its own weight, and accordingly, the light shielding portion 15 protrudes out of the protection accommodating groove 113, and the structure is simple.

Referring to fig. 14 to 16, in some alternative embodiments, the light shielding portion 15 is fixedly connected to the chip holder 13, and when the chip holder 13 is extended and the chip 12 is electrically connected to the contact pins 210, the light shielding portion 15 is extended from the protection accommodating groove 113.

At this time, when the chip holder 13 is not in contact with the driving portion 112, the light shielding portion 15 can be accommodated in the protection accommodating groove 113.

When the printer 20 drives the chip fixing base 13 to move and the chip fixing base 13 abuts against the driving portion 112, the distance between the end of the chip fixing base 13 where the chip 12 is disposed and the ink cartridge body 11 is increased, and at this time, the light shielding portion 15 rotates along with the chip fixing base 13 and extends out of the protection accommodating groove 113.

That is, in this embodiment, the light shielding portion 15 is accommodated in the shield accommodating groove 113 in a natural state. When the ink cartridge 10 is fixedly connected to the printer 20, the light shielding portion 15 extends out of the shielding accommodating groove 113 to shield the detection light of the printer 20.

At this time, the contact surface of the chip holder 13 with the printer 20 is an end surface of the chip holder 13 in the mounting direction X.

When the contact surfaces of the chip holder 13 abutting against the printer 20 are located on both sides of the chip holder 13 in the mounting direction X, referring to fig. 17, at this time, the chip holder 13 and the light shielding portion 15 are independent from each other, and the contact surfaces may be located on either side or both sides of the chip holder 13 in the mounting direction X. Correspondingly, the positions of the printer 20 abutting against the chip holder 13 are also located on both sides of the chip holder 13 in the mounting direction X.

The present embodiment also provides a printing apparatus, including: a printer 20 and the ink cartridge 10, wherein at least one ink cartridge 10 is provided, and the printer 20 is provided with a contact pin 210 corresponding to the ink cartridge 10; the printer 20 is further provided with a mounting portion 21 corresponding to the ink cartridge 10, and the ink cartridge 10 is fixed to the printer 20 via the mounting portion 21.

The printer 20 includes a print head (not shown) and an ink supply portion (not shown) provided between the print head and the cartridge body 11. The cartridge body 11 is provided with a container-like structure for containing ink, such as an ink bag, or a sealed cavity directly formed inside the cartridge body 11. The container-like structure is provided with an ink outlet 114, and the ink outlet 114 communicates with an ink supply part (not shown) of the printer 20. Thus, ink can be delivered to the printhead through the ink outlet 114 and the ink supply to enable the printer 20 to print predetermined text or images. The structure, operation principle and achievable technical effects of the ink cartridge 10 have been described in the above embodiments, and are not described in detail in this embodiment.

The printer 20 also includes contact pins 210, the contact pins 210 being electrically connected to the chip 12 to enable communication between the chip 12 and the printer 20. The present embodiment does not limit the structure of the printer 20.

When the ink cartridge 10 is installed on the printer 20, the printer 20 drives the chip fixing seat 13 to rotate while driving the chip fixing seat 13 to move, the distance between one end of the fixed chip 12 of the chip fixing seat 13 and the contact pin 210 becomes small, namely, the distance between the chip 12 and the contact pin 210 becomes small, until the electric connection part of the chip 12 abuts against the contact pin 210 of the contact pin 210, at this time, the ink cartridge 10 is installed on the printer 20, and the ink cartridge 10 and the printer 20 are relatively fixed.

That is to say, at this moment, the chip fixing seat 13 is disposed between the ink cartridge body 11 and the printer 20, the chip fixing seat 13 is fixed by the assembly fit between the ink cartridge body 11 and the printer 20, since the connection between the ink cartridge body 11 and the printer 20 is stable, as long as the ink cartridge body 11 does not move relative to the printer 20, for example, the ink cartridge 10 is detached from the printer 20, the chip fixing seat 13 can be stably supported between the ink cartridge body 11 and the printer 20, that is, the electrical connection between the chip 12 and the contact pin 210 is stable.

In some alternative embodiments, the mounting portion 21 is a mounting groove formed on the printer 20, and the mounting portion has a protruding abutting portion therein, and the abutting portion abuts against the chip fixing seat when the ink cartridge is mounted on the printer.

Thus, the ink cartridge 10 is fixedly connected to the printer 20 by being inserted into the mounting groove. In the process of inserting the ink cartridge 10 into the mounting groove, the partial structure of the inner wall surface of the mounting groove, namely the abutting part 22, can drive the chip fixing seat 13 to move and rotate. The process of the abutting portion 22 driving the chip fixing base 13 to move relative to the ink cartridge body 11 is described in the above embodiments, and is not described in detail in this embodiment.

The abutting portion 22 may be a protruding structure of an inner wall surface of the mounting groove, and the protruding structure may be any other protruding block structure, which is not limited in this embodiment.
