As shown in fig. 2 and 3, the cartridge mounting portion 200 includes a frame body having an opening 201 formed to penetrate one surface of the frame body, and a mounting chamber in which the ink cartridge 1 is mounted. The ink cartridge 1 is configured to be inserted into and removed from the frame via the opening 201. The frame has a groove 208 formed in a bottom surface defining a lower end of an inner space of the frame, the groove 208 extending in the front direction 51. When the ink cartridge 1 is inserted into the groove 208 formed in the bottom surface of the frame body, the ink cartridge 1 is guided in the front direction 51. The frame is configured to receive four ink cartridges 1 that store cyan ink, magenta ink, yellow ink, and black ink, respectively. An ink needle 202, a stylus 203, a positioning column 204, a first optical sensor 205, a second optical sensor 206, and a coupling member 207 are provided in each of the mounting grooves of the cartridge 1 in the cartridge mounting portion 200.

The first optical sensor 205 and the second optical sensor 206 are each composed of a pair of optical sensors, and have an optical transmitter at one end and an optical receiver at the other end. The first optical sensor 205 is located above the second optical sensor 206 in the height direction of the housing 10. The coupling member 207 is provided near the opening of the cartridge mounting portion 200, and the coupling member 207 is rotatable about the axis when receiving an impact of a force. When the ink cartridge 1 is mounted in the cartridge mounting portion 200, the ink needle 202 is connected with the ink outlet of the ink cartridge 1, and ink supply of the ink cartridge 1 to the cartridge mounting portion 200 is achieved; the contact pin 203 is contacted with the chip 12 of the ink box 1 to realize the connection of electric signals; the positioning column 204 is abutted against the elastic jack column of the ink box 1; the light signal emitted from the first optical sensor 205 is blocked by the light blocking portion 11 of the ink cartridge 1 or the transmission path is changed; the light signal emitted from the second optical sensor 206 is blocked or the transfer path is changed by the ink amount detecting portion of the ink cartridge 1; the coupling member 207 is coupled to the operation portion of the ink cartridge 1 to fix the ink cartridge 1.

As shown in fig. 1, the case 10 is a container for holding ink, and has a substantially rectangular parallelepiped shape, and has a front end surface 101, an upper end surface 102, a rear end surface 103, a lower end surface 104, a left end surface 105, and a right end surface 106, wherein the front end surface 101 and the rear end surface 103 are disposed opposite to each other, the upper end surface 102 and the lower end surface 104 are disposed opposite to each other, the left end surface 105 and the right end surface 106 are disposed opposite to each other, the front end surface 101, the rear end surface 103, the left end surface 105, and the right end surface 106 are respectively connected perpendicularly to the upper end surface 102, and the front end surface 101, the rear end surface 103, the left end surface 105, and the right end surface 106 are respectively connected perpendicularly to the lower surface 114. The housing 10 has an ink storage chamber for storing ink.

The upper side of the housing 10 is provided with a light shielding portion 11, a chip 12, and an operating portion 13 in this order from front to rear in the front direction 51.

The light shielding portion 11 is mounted on the upper end surface 102, and the light shielding portion 11 is for insertion between the light generator and the light receiver of the first optical sensor 205 of the cartridge mounting portion 200 of the inkjet printer. Specifically, when the ink cartridge 1 is mounted to the cartridge mounting portion 200 of the ink jet printer, the first optical sensor 205 in the cartridge mounting portion 200 emits light in the width direction of the housing 10, and since the light shielding portion 11 is located between the light emitter and the light receiver of the first optical sensor 205 when mounted to the cartridge mounting portion 200, the light emitted by the light emitter of the first optical sensor 205 can be blocked or attenuated, and therefore, the change in the intensity state of the light received by the light receiver of the first optical sensor 205 can be detected, whether or not the ink cartridge 1 is properly mounted to the cartridge mounting portion 200.

The light shielding portion 11 is elastically deformable, and the light shielding portion 11 has a plurality of surfaces, at least one of which has an arc for reducing a contact area of the light shielding portion 11 against an impact. Specifically, when the ink cartridge 1 is loaded into the mounting chamber of the cartridge mounting portion 200, in the case where the ink cartridge 1 is impacted during use or transportation, the surface of the light shielding portion 11 having the arc is impacted, so that the contact area of the light shielding portion 11 impacted can be reduced, the light shielding portion 11 having elastic deformation can increase the impact resistance of the light shielding portion, and thus the possibility of damage of the light shielding portion can be reduced.

The light shielding portion 11 may be made of a material having elasticity. In some examples, the light shielding portion 11 is a silica gel light shielding portion, and the material of the silica gel light shielding portion is silica gel.

The light shielding portion 11 may include a multi-faceted elastic light shielding plate. In other implementations, fig. 8 is a perspective view of another ink cartridge according to an embodiment of the present utility model; fig. 9 is a schematic view of the light shielding part in fig. 1 disposed on a mounting base. As shown in fig. 8 and 9, the light shielding portion 11 may include a plurality of cylindrical elastic light shielding columns, and the plurality of elastic light shielding columns may be brush-type.

As shown in fig. 6, the chip 12 may store information of lot number, manufacturing date, color, etc. of the ink cartridge 1. The chip 12 is provided with at least one electrical interface 121, the electrical interface 121 being adapted to be connected to a contact pin 203 of the cartridge mounting portion 200 so that the information data of the ink cartridge 1 can be read by the ink jet printer. Specifically, the chip 12 in this embodiment is provided with three electrical interfaces 121, and the three electrical interfaces 121 may be a hot electrode, a ground electrode, and a signal electrode, respectively. The three electrical interfaces 121 have the same width in the width direction of the housing 10, and the three electrical interfaces 121 are arranged at intervals in the width direction of the housing 10.

The chip 12 is provided with a groove and a through hole, and the housing 10 is provided with a protrusion matched with the groove and the through hole of the chip 12, and the chip 12 is fixed on the housing 10 by means of thermal welding or the like.

As shown in fig. 4 and 7, the operation portion 13 is provided with a shaft that rotates around the housing 10, and the operation portion 13 is capable of facilitating the operation of the ink cartridge 1 by the user, and the user mounts and removes the ink cartridge 1 through the operation portion 13. The operating portion 13 is provided with a locking section 131 and an unlocking section 132, the locking section 131 being located at the rear side of the chip 12 and at the front side of the unlocking section 132. When the ink cartridge 1 is mounted in the cartridge mounting portion 200, the lock section 131 abuts against the coupling member 207 on the cartridge mounting portion 200, and the ink cartridge 1 is immovable in the front direction 51 and the rear direction 52, so that the ink cartridge 1 is fixed in the cartridge mounting portion 200. When the ink cartridge 1 is removed from the cartridge mounting portion 200, the lock-out section 131 is lifted by pressing the unlock section 132, and the lock-out section 131 brings the coupling member 207 up, and the ink cartridge is movable in the rear direction 52, thereby releasing the lock of the cartridge mounting portion 200 to the ink cartridge 1.

As shown in fig. 1, the front side of the housing 10 is provided with an elastic jack 14, a detection portion 15, and an ink outlet 16 in this order from the bottom to the bottom in the height direction of the housing 10.

As shown in fig. 4, the elastic jack posts 14 are made of an elastic material, and the elastic jack posts 14 can be restored to an original state after being compressed. When the ink cartridge 1 is mounted to the cartridge mounting portion 200 of the ink jet printer, the elastic jack 14 abuts against the positioning column 204 of the cartridge mounting portion 200, and therefore the ink cartridge 1 receives an elastic force in a direction opposite to the front direction 51, which is small, and the elastic force can be canceled by a frictional force generated between the ink cartridge 1 and the cartridge mounting portion 200, so that the ink cartridge 1 can remain in the cartridge mounting portion 200.

As shown in fig. 4, the detection portion 15 protrudes outward from the front side of the housing 10, and the detection portion 15 is provided with a chamber communicating with the ink storage chamber of the housing 10. In the present embodiment, the detecting portion 15 is located between the light emitter and the light receiver of the second optical sensor 206 when mounted to the cartridge mounting portion 200, and thus can block or attenuate the light emitted from the second optical sensor 206, and by detecting the change in the intensity state of the light received by the light receiver side of the second optical sensor 206, it can be detected whether the ink amount in the ink cartridge 1 is smaller than the predetermined ink amount.

When the ink is stored in the detection portion 15, the ink amount of the ink storage chamber of the housing 10 is larger than the predetermined ink amount, the light of the light emitter of the second optical sensor 206 cannot be emitted to the light receiver side, and the detection portion 15 is in a non-light transmitting state; when the ink in the detection portion 15 is exhausted, the ink amount of the ink storage chamber of the housing 10 is smaller than the predetermined ink amount, and the light of the light emitter of the second optical sensor 206 can be emitted to the light receiver side while the detection portion 15 is in the light transmitting state. By the state of the detecting portion 15, it is possible to detect whether or not the amount of ink in the ink storage chamber of the housing 10 is smaller than a predetermined amount of ink.

As shown in fig. 4, the ink outlet 16 is located at the lower side of the light shielding portion 11, and the ink outlet 16 is connected to the ink needle 202 when the ink cartridge 1 is mounted to the cartridge mounting portion 200 of the ink jet printer, so that ink in the ink storage chamber of the housing 10 can flow into the cartridge mounting portion 200 through the ink outlet 16, and ink supply of the ink cartridge 1 to the cartridge mounting portion 200 of the ink jet printer is realized.

The ink cartridge 1 is inserted into the frame body in the front direction 51 through the opening in the cartridge mounting portion 200, and when the ink cartridge 1 is inserted into the groove 208 formed in the bottom surface of the frame body, the ink cartridge 1 is guided in the insertion direction, at which time at least a portion of the upper end surface 102 and the lower end surface 104 of the ink cartridge 1 will come into contact with the inner wall of the cartridge mounting portion 200. With the insertion of the ink cartridge 1, the coupling member 207 of the cartridge mounting portion 200 is coupled with the locking section 131 of the operating portion 13 of the ink cartridge 1, which means that the ink cartridge 1 is mounted in place in the cartridge mounting portion 200, and the user can continue to push the operating portion 13 in the forward direction 51 by feedback stop of such abutment.

When the ink cartridge 1 is inserted into the cartridge mounting portion 200 of the ink jet printer, the chip 12 makes electrical contact with the contact pins 203 in the cartridge mounting portion 200, so that the ink jet printer can read the information data of the ink cartridge 1. The operation unit 13 abuts against the coupling member 207 on the cartridge mounting unit 200, and fixes the ink cartridge 1 in the cartridge mounting unit 200. The first optical sensor 205 in the cartridge mounting portion 200 emits light in the width direction of the housing 10, and the light shielding portion 11 is interposed between the light emitter and the light receiver of the first optical sensor 205 when the ink cartridge 1 is loaded into the cartridge mounting portion 200, for blocking or attenuating the light emitted by the first optical sensor 205, and the cartridge mounting portion 200 detects whether the ink cartridge 1 is properly mounted in the cartridge mounting portion 200 by detecting a change in the intensity state of the light received by the light receiver side. The second optical sensor 206 in the cartridge mounting portion 200 emits light in the width direction of the housing 10, and the detecting portion 15 is interposed between the light emitter and the light receiver of the second optical sensor 206 when the ink cartridge 1 is loaded into the cartridge mounting portion 200, for blocking or attenuating the light emitted by the second optical sensor 206, and by detecting a change in the intensity state of the light received by the light receiver side, it is possible to detect whether the ink amount in the ink cartridge 1 is smaller than a predetermined ink amount. The elastic jack posts 14 abut against the positioning posts 204 in the cartridge mounting portion 200. The ink outlet 16 is in fluid connection with the ink needle 202 of the cartridge mounting portion 200, so that ink in the ink cartridge 1 can flow into the cartridge mounting portion 200 through the ink outlet 16, and ink supply of the ink cartridge 1 to the cartridge mounting portion 200 is realized.

As shown in fig. 2 and 4, since the ink cartridge 1 is guided mainly by the groove 208 provided in the cartridge mounting portion 200 during insertion into the cartridge mounting portion 200, the light shielding portion 11 is provided on the upper end surface 102 of the housing 10 at a relatively long linear distance from the guide groove 208. Therefore, during the process of mounting the ink cartridge 1 to the cartridge mounting portion 200, the light shielding portion 11 is likely to be displaced from the insertion direction of the ink cartridge 1. The light shielding part 11 in the prior art is made of a rigid material, the shape is fixed, and under the condition that the light shielding part 11 deviates from the insertion direction of the ink cartridge 1, the light shielding part 11 may be clamped between the light emitter of the first optical sensor 205 and the light receiver, so that the ink cartridge 1 cannot continue to move along the insertion direction, the light shielding part 11 cannot effectively block or attenuate the light emitted by the first optical sensor 205, the intensity of the light received by one side of the light receiver is not changed by the cartridge mounting part 200, and the ink cartridge 1 is not correctly mounted in the cartridge mounting part 200, so that the ink cartridge 1 needs to be reloaded. The light shielding part 11 of this application embodiment can elastically deform, the shape of light shielding part 11 is changeable, under the circumstances that the light shielding part 11 skew the direction of insertion of ink horn 1 appears, when the light shielding part 11 probably blocked in the centre of the light emitter of first optical sensor 205 and light receiver, the skew of light shielding part 11 is adapted to through shape change to light shielding part 11 for ink horn 1 can continue to remove along the direction of insertion, light shielding part 11 can effectively block or attenuate the light that first optical sensor 205 launched, the intensity of the light that box installation department 200 received through detecting light receiver one side changes, in box installation department 200 is installed to ink horn 1 correctly, need not reload ink horn 1, thereby can improve the reliability of inkjet printer.

Alternatively, the light shielding portion 11 has a deformed state and a non-deformed state, the deformed state and the non-deformed state being mutually convertible, the light shielding portion 11 being adapted to change from the non-deformed state to the deformed state upon receiving an impact force. By doing so, the impact resistance of the light shielding portion 11 can be increased, so that the possibility of damage of the light shielding portion 11 can be reduced.

Wherein, as shown in fig. 5, the shielding portion 11 includes a front surface 111, a rear surface 112, and a side surface 113, the front surface 111 and the rear surface 112 being disposed opposite to each other in the length direction of the housing 10, the side surface 113 being located between the front surface and the rear surface, the front surface 111, the rear surface 112, and the side surface 113 each having an arc.

When the light shielding portion 11 receives an impact force, the light shielding portion 11 is in a deformed state; when the impact force applied to the light shielding portion 11 disappears, the light shielding portion 11 changes from the deformed state to the non-deformed state.

The impact force received by the light shielding portion 11 may be from the pressure of the components of the cartridge mounting portion 200. In an alternative embodiment, the impact force received by the light shielding portion 11 may be from the frame of the cartridge mounting portion 200, or may be from the light emitter and/or the light receiver of the first optical sensor 205.

Further, the light shielding portion 11 may have a width in the non-deformed state larger than a distance between the light generator and the light receiver of the first optical sensor 205; the width of the light shielding portion 11 in the deformed state may be less than or equal to the distance between the light generator and the light receiver of the first optical sensor 205.

In an alternative implementation, the width of the light shielding portion 11 in the non-deformed state may be slightly larger than the distance between the light emitter and the light receiver of the first optical sensor 205. The light shielding portion 11 in the non-deformed state is configured to block or attenuate light emitted from the light emitter of the first optical sensor 205, and the light shielding portion 11 is deformed into a deformed state, such as the frame or the light emitter and/or the light receiver of the first optical sensor 205, by pressure of the internal components of the cartridge mounting portion 200 during mounting of the ink cartridge 1 to the mounting chamber of the cartridge mounting portion 200 in the insertion direction in the upright posture. The width of the light shielding portion 11 in the deformed state at this time is smaller than or equal to the distance between the light emitter and the light receiver of the first optical sensor 205. When the ink cartridge 1 is removed from the mounting chamber of the cartridge mounting portion 200 in the removal direction, the pressure applied to the light shielding portion 11 disappears, and the light shielding portion 11 returns to the non-deformed state.

Alternatively, the width of the light shielding portion 11 in the non-deformed state is greater than or equal to the width of the electrical interface 121.

Wherein the width of the electrical interface 121 is less than or equal to 2.3mm and the width of the first optical sensor 205 is 2.1-3 mm.

In an alternative embodiment, the electrical interface 121 has a width of 0.7mm and the first optical sensor 205 has a width of 2.6mm.

In another alternative embodiment, the electrical interface 121 has a width of 1.7mm and the first optical sensor 205 has a width of 2.9mm.
