In the prior art, the inkjet imaging device is provided with a detection device for determining whether the ink cartridge is correctly installed and / or whether the ink cartridge is an allowed installation. The ink cartridge is provided with an ink cartridge detection device that can be detected by the detection device. After the ink cartridge is installed, the inkjet imaging device first detects the ink cartridge, and only after the detection is confirmed to be correct does the inkjet imaging device allow printing operations to be performed. The ink cartridge in the prior art is also provided with an ink level detection device for detecting the ink level. When the ink level in the ink cartridge is insufficient, the inkjet imaging device sends a prompt to the user.

[0032] The structure of the ink cartridge involved in the present application and other aspects will be further described in detail through specific embodiments and with reference to the accompanying drawings.

[0033] Embodiment 1

[0034] As shown in Figures 1-4 , the ink cartridge 1 is detachably installed in the inkjet imaging device having the ink cartridge mounting portion 100, the ink cartridge mounting portion 100 has the ink cartridge mounting position 110 for installing the ink cartridge 1, the ink cartridge 1 includes the shell 2, the shell 2 is formed with the ink chamber 20 for accommodating ink, the ink cartridge 1 further has the ink outlet 7 communicating with the ink chamber 20, the ink outlet 7 is used for supplying the ink in the ink chamber 20 to the inkjet imaging device; the shell 2 includes the bottom shell 21 and the cover 22 combined with each other, the ink chamber 20 is formed between the bottom shell 21 and the cover 22; the ink cartridge mounting portion 100 is provided with one or more ink cartridge mounting positions 110, each ink cartridge mounting position 110 can install one ink cartridge 1, and different ink cartridge mounting positions 110 can be used to install ink cartridges 1 of different colors; as shown in Figures 7-9 , the ink cartridge mounting portion 100 further includes the optical sensing member 120 arranged in the ink cartridge mounting position 110, the optical sensing member 120 includes the light emitting portion 121 and the light receiving portion 122 arranged oppositely and spaced apart, wherein the light receiving portion 122 is used for receiving the light emitted by the light emitting portion 121.

[0035] For the sake of clarity of the following description, the direction parallel to the mounting direction of the ink cartridge 1 to the ink cartridge mounting portion 100 is defined as the front-rear direction, and the ink cartridge 1 is mounted forwardly, the direction intersecting with the front-rear direction is defined as the left-right direction, and in the posture of the ink cartridge 1 mounted to the ink cartridge mounting portion 100, the left side of the ink cartridge 1 is the left side, the right side is the right side, the upper side is the upper side, and the lower side is the lower side when viewed from the rear to the front.

[0036] As shown in Figure 3 and Figure 7 , the upper side of the ink cartridge 1 is further provided with a detected device for cooperating with the optical sensor 120, which is used to detect whether the ink cartridge 1 is installed in place (installed to a predetermined position capable of imaging by the imaging device) and the ink remaining amount, and the detected device includes a reflecting member 3 (also can be called a first detection component) for cooperating with the optical sensor 120 to detect whether the ink cartridge 1 is installed, and the reflecting member 3 is movably connected with the housing 2; the reflecting member 3 has a first position and a second position, when the reflecting member 3 is in the first position, the reflecting member 3 is located between the light emitting portion 121 and the light receiving portion 122 along the left-right direction, and the reflecting member 3 is used to attenuate the light emitted by the light emitting portion 121, so that the light receiving portion 122 cannot receive the light emitted by the light emitting portion 121 along the left-right direction, and when the reflecting member 3 is in the second position, the reflecting member 3 does not attenuate the light emitted by the light emitting portion 121, so that the light receiving portion 122 can receive the light emitted by the light emitting portion 121; thus, the optical sensor 120 can detect whether the ink cartridge 1 is installed in place; the specific attenuation method, for example, can be that the light receiving portion 122 cannot receive the light intensity required to realize the detection action by shielding or attenuating the light emitted by the light emitting portion 121, or the light emitted by the light emitting portion 121 enters the ink cavity 20 and is scattered in the ink.

[0037] In some embodiments, the reflecting member 3 can also be provided with a light-transmitting member, when the reflecting member 3 is in the second position, the light emitted by the light emitting portion 121 can pass through the light-transmitting member and be received by the light receiving portion 122, but the light intensity received by the light receiving portion 122 is lower than the light intensity required to realize the detection action, which can also achieve the purpose of the present application.

[0038] Specifically, as Figures 3-5As shown in the figures, the reflecting member 3 has a first body 30 and an accessory 31 arranged on the first body 30, and further comprises a connecting portion 32 connected with the first body 30 and a mating portion 321 formed on the connecting portion 32, and the bottom shell 21 is formed with a mating portion 211 for mating with the mating portion 321, and through the mating of the mating portion 321 and the mating portion 211, the reflecting member 3 is enabled to rotate around a rotation axis which is not parallel to the up-down direction, along the front-back direction, and the reflecting member 3 further has a first end 3a and a second end 3b respectively located at two ends of the first body 30 and the mating portions; the ink cartridge 1 further has a first elastic member 51 for forcing the reflecting member 3 to have a tendency to move towards the second position, and one end of the first elastic member 51 abuts against the second end 3b and the other end abuts against the shell 2.

[0039] In some embodiments, the mating portion 321 can be arranged on the bottom shell 21 and the mating portion 211 can be arranged on the first body 30, as long as the reflecting member 3 is enabled to rotate around a rotation axis which is not parallel to the up-down direction.

[0040] In some embodiments, the accessory 31 is formed by extending on the first body 30; and the first elastic member 51 is preferably a spring, but is not limited thereto, and for example, a tension spring, a rubber or a sponge or the like elastic material can also be used.

[0041] In some embodiments, the accessory 31 can be arranged separately from the first body 30 and is fixedly connected to the first body 30.

[0042] As shown in the figures, Figure 3 , Figure 4 and Figure 6 the ink cartridge 1 further has a movable member 4 for mating with the reflecting member 3, and the movable member 4 is movable relative to the shell 2 and the reflecting member 3, and specifically, the movable member 4 has a second body 40 and a trigger portion 44 connected with the second body 40, and further comprises a restricted portion 43 formed by extending on at least one of the second body 40 and the trigger portion 44, and the shell 2 is formed with a restriction portion 212 for mating with the restricted portion 43, and the restriction portion 212 and the restricted portion 43 form a sliding-mating movement guide structure to guide the movable member 4 to move forward and backward relative to the shell 2 and the reflecting member 3.

[0043] The movable member 4 further has a receiving portion 42 formed on the second body 40, and further has a first guide surface 41a and a second guide surface 41b respectively located on two sides of the receiving portion 42 in the front-rear direction, the receiving portion 42, the first guide surface 41a and the second guide surface 41b are all used to cooperate with the accessory 31 to move the reflecting member 3 between the first position and the second position; the movable member 4 has an initial state and a triggered state, when the movable member 4 is in the initial state, the accessory 31 cooperates with the first guide surface 41a, and the reflecting member 3 is located at the first position; when the movable member 4 is in the triggered state, the accessory 31 cooperates with the second guide surface 41b or the receiving portion 42, and the reflecting member 3 is located at the first position or the second position; specifically, as shown in Figure 7 the ink cartridge mounting portion 100 further includes an abutting portion 130 used to cooperate with the triggering portion 44 to force the movable member 4 to move from the initial state to the triggered state.

[0044] Preferably, the movement of the reflecting member 3 between the first position and the second position at least causes displacement in the up-down direction, and the second position is located above the first position; in the embodiment, the movement of the reflecting member 3 between the first position and the second position is realized by displacement in the rotation direction.

[0045] Preferably, the switching of the movable member 4 between the initial state and the triggered state at least causes displacement in the front-rear direction, and the initial state is located in front of the triggered state; in the embodiment, the switching of the movable member 4 between the initial state and the triggered state is realized by movement in the front-rear direction.

[0046] In the embodiment, the triggered state should be understood as that as long as the triggering portion 44 abuts against the abutting portion 130, the movable member 4 is triggered, and the subsequent state of the movable member 4 is always the triggered state.

[0047] In some embodiments, the abutting portion 130 is a protection arm arranged on one side of the optical sensing member 120 and used to protect the optical sensing member 120, specifically, the abutting portion 130 is a rearward-facing surface.

[0048] In the process of installing the ink cartridge 1 to the ink cartridge installation part 100, the accessory 31 is first in the position of cooperating with the first guide surface 41a, at this time the reflecting member 3 is in the first position, the light receiving part 122 cannot receive the light emitted by the light emitting part 121, that is, the reflecting member 3 is at the same height as the optical sensing member 120, and the movable member 4 is in the initial state; the ink cartridge 1 continues to move forward until the trigger part 44 abuts against the abutting part 130, so that the movable member 4 moves backward, at this time, the movable member 4 is in the triggered state and is kept, when the accessory 31 cooperates with the accommodating part 42, under the elastic action of the first elastic member 51, the reflecting member 3 rotates around the cooperating part 211 in the counterclockwise N direction, the reflecting member 3 moves from the first position to the second position, at this time the light receiving part 122 can receive the light emitted by the light emitting part 121, then the ink cartridge 1 continues to move forward, the accessory 31 gradually cooperates with the second guide surface 41b, the reflecting member 3 rotates around the cooperating part 211 in the clockwise M direction against the elastic action of the first elastic member 51, and moves from the second position to the first position, at this time the light receiving part 122 no longer receives the light emitted by the light emitting part 121; thus, the inkjet imaging device detects that the ink cartridge 1 is installed in place.

[0049] In some embodiments, the accessory 31 is arranged on the movable member 4, and the accommodating part 42 is arranged on the reflecting member 3, only the movement space of the reflecting member 3 in the up-down direction needs to be ensured.

[0050] The second elastic member 52 is further arranged in the ink cartridge 1, the second elastic member 52 is used to force the movable member 4 to have a tendency to move toward the initial state, one end of the second elastic member 52 abuts against the movable member 4, and the other end abuts against the shell 2, the second elastic member 52 is preferably a spring, but is not limited thereto, for example, a tension spring, a rubber or a sponge, or other elastic materials can also be used.

[0051] As Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, the detected device further comprises a prism 6 (may also be referred to as a second detection component) arranged in the ink cavity 20, which is used to cooperate with the reflecting member 3 and the optical sensing piece 120 to detect the ink amount in the ink cartridge 1 when the reflecting member 3 is located at the first position; the prism 6 extends along the front-rear direction and the up-down direction, and has a whole conical shape and a first side surface 6a and a second side surface 6b; the shell 2 further comprises an upper side plate 23 arranged above the ink cavity 20, and the reflecting member 3 and the prism 6 are located on both sides of the upper side plate 23 along the up-down direction, that is, the reflecting member 3 is located outside the ink cavity 20, and at least a part of the upper side plate 23 is made of a light-transmitting material; after the ink cartridge 1 is installed to the ink cartridge installation position 110 of the ink cartridge installation part 100, when the amount of ink in the ink cavity 20 is sufficient, that is, the ink in the ink cavity 20 can cover the first side surface 6a and the second side surface 6b of the prism 6, the light emitted by the light emitting part 121 is scattered after being reflected by the ink in the ink cavity 20 through the reflecting member 3, so that the light receiving part 122 cannot receive the light emitted by the light emitting part 121 (as shown in Figure 8 When the amount of ink in the ink cavity 20 is insufficient, the ink is separated from the first side surface 6a and the second side surface 6b, the light emitted by the light emitting part 121 is reflected to the prism 6 through the reflecting member 3, and then reflected to the side of the reflecting member 3 close to the light receiving part 122 through the prism 6, so that the light receiving part 122 receives the light emitted by the light emitting part 121 (as shown in Figure 9 Thus, the inkjet imaging device detects that the ink amount is insufficient and sends a prompt to the user.

[0052] As described above, the reflecting member 3 can not only be used to detect whether the ink cartridge 1 is installed in place, but also be used to detect the ink amount, which effectively simplifies the structure of the ink cartridge 1;

[0053] In addition, under the action of the first elastic member, the reflecting member 3 can move relative to the shell 2 from the first position to the second position located above the first position, in other words, when the ink cartridge 1 is bumped or falls, the reflecting member 3 can buffer the component force of the impact from above the ink cartridge to below the ink cartridge 1; at the same time, under the action of the second elastic member, the movable piece 4 can move relative to the shell from the triggered state to the initial state located in front of the initial state, in other words, when the ink cartridge 1 is bumped or falls, the movable piece 4 can buffer the component force of the impact from the front of the ink cartridge 1 to the rear of the ink cartridge, thus effectively alleviating the situation that the ink cartridge is damaged and cannot be correctly detected by the inkjet imaging device.

[0054] Embodiment 2

[0055] As Figure 10 , Figure 11 , Figure 12A , Figure 12B , Figure 12C and Figure 12DAs shown, the following will introduce Embodiment 2 of this application. The parts that are the same as those in Embodiment 1 will not be repeated in this embodiment. The difference from Embodiment 1 is that the structure of the reflective member 3 used to detect whether the ink cartridge 1 is installed in place is different, and the connection method between the reflective member 3 and the housing 2 is different.

[0056] like Figure 10 and Figure 11 As shown, in this embodiment, the detection device has a movable part for cooperating with the reflective member 3. The movable part is fixedly connected to the reflective member 3. The movable part is the trigger part 31 connected to the reflective member 3. The trigger part 31 extends in the front-back direction and is used to abut against the contact part 130 of the ink cartridge mounting part 100. In this embodiment, the contact part 130 is the inner wall of the ink cartridge mounting part 100. The reflective member 3 also has an attachment 32 disposed on the first main body 30. The attachment 32 extends in the left-right direction and is used to abut against the housing 2. The reflective member 3 is movably connected to the housing 2, and the reflective member 3 has a first position and a second position. In the first position, the reflective member 3 attenuates the light emitted by the light emitting part 121, so that the light receiving part 122 cannot receive the light emitted by the light emitting part 121. In the second position, the reflective member 3 does not attenuate the light emitted by the light emitting part 121, so that the light receiving part 122 can receive the light emitted by the light emitting part 121. Thus, the optical sensor 120 can detect whether the ink cartridge 1 is installed in place.

[0057] In this embodiment, the second position is located above the first position. When the reflective member 3 moves between the first position and the second position, it generates displacement in both the vertical direction and the front-back direction.

[0058] In this embodiment, the initial state is located in front of the trigger state. When the movable part 4 switches between the initial state and the trigger state, it generates displacement in both the vertical direction and the forward and backward direction.

[0059] Specifically, at least one of the bottom shell 21 and the top cover 22 has a guide rail 210 for cooperating with the attachment 32. In the vertical direction, the guide rail has a high position area 210a and a low position area 210b that are arranged opposite each other, and in the front-back direction, the high position area 210a and the low position area 210b are arranged adjacent to each other. The attachment 32 forms a sliding engagement with the guide rail 210 to guide the reflector 3 to move in the front-back direction and the vertical direction. Similarly, the reflector 3 also has the above-mentioned initial state and trigger state. In the initial state, the attachment 32 cooperates with the low position area 210b. In the trigger state, the attachment 31 cooperates with either the high position area 210a or the low position area 210b.

[0060] In this embodiment, the triggering state should be understood as follows: as long as the triggering part 31 abuts against the contacting part 130, the reflective member 3 is triggered, and all subsequent states of the reflective member 3 are triggering states.

[0061] The ink cartridge 1 also has a first elastic element 51 for forcing the reflective member 3 to move toward the second position / initial state. One end of the first elastic element 51 abuts against the reflective member 3 and the other end abuts against the housing 2. The first elastic element 51 is preferably a spring, but it can also be made of elastic materials such as tension springs, rubber or sponge.

[0062] like Figures 12A-12D As shown, during the process of installing ink cartridge 1 into ink cartridge mounting part 100, the accessory 32 first engages with the low position area 210b. At this time, the reflective member 3 is in the second position, and the light receiving part can receive the light emitted by the light emitting part.
