[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0028] [Example 1]

[0029] Figure 1 It is a three-dimensional diagram of the ink cartridge involved in the first embodiment of the utility model; Figure 2 is along Figure 1 A cross-sectional view cut along the direction indicated by BB; Figure 3 After the ink cartridge involved in the first embodiment of the utility model is combined with the valve mechanism on the device side, Figure 1 A cross-sectional view taken in the direction indicated by line BB.

[0030] As shown in the figure, the ink cartridge 10 is polygonal in shape as a whole. For the convenience of description, the length direction of the ink cartridge 10 is defined as the front-to-back direction, the width direction is the left-to-right direction, and the height direction is the up-down direction. The size of the ink cartridge 10 is the largest in the front-to-back direction, the size in the height direction is the second largest, and the size in the width direction is the smallest. The ink cartridge 10 is first installed forward along the front-to-back direction, and then rotated backward and downward. Finally, the ink cartridge 10 reaches the predetermined installation position of the device.

[0031] The ink cartridge 10 includes a shell 11 forming an ink cavity 109 and an ink outlet 16 disposed on the shell 11. The ink outlet 16 is used to discharge the ink in the ink cavity 109 outward. Further, the ink cartridge 10 also includes an adapter (not shown) combined with the shell 11. The ink outlet 16 is exposed through the adapter. The provision of the adapter can, on the one hand, improve the versatility of the ink cartridge 10 so that the ink cartridge 10 can be compatible with various types of imaging devices. On the other hand, when the manufacturing precision of the shell 11 is not high or it is worn / modified, the shell 11 can be precisely matched with the imaging device through the adapter. Furthermore, the ink cartridge 10 also includes a plurality of electrically conductive contacts. A chip 12 having a connected storage unit and electrical contacts, wherein the storage unit is used to store various parameter information of the ink cartridge 10, and the electrical contacts are used to make electrical contact with the device to establish an electrical connection. It is feasible that the chip 12 can be set on at least any one of the shell 11 and the adapter. In particular, when the chip 12 is set on the adapter, when the ink in the shell 11 is consumed, the user only needs to replace the shell 11, and the adapter equipped with the chip 12 can continue to be used, thereby reducing the user's usage cost. It can be seen that in some embodiments, the adapter does not need to be set, and the chip 12 is directly set on the shell 11.

[0032] The housing 11 has a lower surface 11b facing downward, through which the ink outlet 16 is exposed, and at least the electrical contacts of the chip 12 are arranged in front of the ink outlet 16. When the ink cartridge 10 is installed forward toward the device, the electrical contacts are in electrical contact with the contact pins in the device, and then the ink cartridge 10 is rotated toward the rear and downward until the ink outlet 16 is combined with the device-side valve mechanism 22 provided in the device.

[0033] The ink outlet portion 16 includes an ink outlet channel 16d connected to the ink chamber 109, wherein the ink outlet channel 16d has an ink outlet port 16c at its lower end and a channel inlet 16d1 at its upper end. The ink outlet channel 16d is connected to the ink chamber 109 through the channel inlet 16d1, and is connected to the external atmosphere through the ink outlet port 16c. Therefore, the ink in the ink chamber 109 enters the ink outlet channel 16d through the channel inlet 16d1, and then flows out through the ink outlet port 16c.

[0034] like Figure 3As shown, the device side valve mechanism 22 includes a sealing body 221, a pushed piece 223 connected to the sealing body 221, and a device side elastic piece 222 abutting against the sealing body 221. The sealing body 221 is maintained in a state of sealing the device side valve mechanism 22 under the forced pushing action of the device side elastic piece 222. As the ink cartridge 10 rotates toward the rear and lower part, the device side valve mechanism 22 is opened, and the ink in the ink cartridge 10 can be supplied to the device through the device side valve mechanism 22. For example, by providing a force-applying piece in the ink cartridge 10 that can apply a pushing force to the pushed piece 223, when the ink cartridge 10 rotates toward the rear and lower part, the force-applying piece applies a pushing force to the pushed piece 223 to release the seal of the device side valve mechanism 22.

[0035] Furthermore, the push piece 223 is surrounded by a device-side shell having an ink receiving chamber 21b1. When the ink cartridge 10 is combined with the device-side valve mechanism 22, the ink outlet channel 16d is connected to the ink receiving chamber 21b1, and the ink entering the ink outlet channel 16d from the ink outlet chamber 109 can enter the ink receiving chamber 21b1.

[0036] like Figure 2 As shown, the pressing member 11m disposed in the housing 11 can be regarded as a force-applying member, and the pressing member 11m includes an intermediate rod 11m2 and a pressing portion 11m1 and a pushing portion 11m3 respectively located at both ends of the intermediate rod 11m2. In the up-down direction, the intermediate rod 11m2 passes through the ink cavity 109, the pressing portion 11m1 is located above the housing 11, and the pushing portion 11m3 is located in the ink outlet channel 16d. At the same time, the pushing portion 11m3 is also used to seal the channel entrance 16d1. When the user applies a downward pressing force to the pressing portion 11m1, the pushing portion 11m3 moves downward and abuts against the pushed member 223, the channel entrance 16d1 opens, the pushed member 223 presses the device-side elastic member 222, and the sealing body 221 no longer seals the device-side valve mechanism 22, so that the ink can be supplied to the device through the device-side valve mechanism 22.

[0037] To prevent ink from dripping from the ink outlet 16c, the ink outlet portion 16 also includes a liquid adsorption member 16j arranged near the ink outlet 16c, that is, the liquid adsorption member 16j is arranged adjacent to the ink outlet 16c, and the liquid adsorption member 16j is arranged around the circumferential direction of the ink outlet 16c. Along the ink flow direction, the liquid adsorption member 16j is located upstream of the ink outlet 16c, and along the radial direction of the ink outlet 16c, the liquid adsorption member 16j directly faces the ink outlet 16c. In this way, the ink that has not entered the ink receiving cavity 21b1 in the ink outlet channel 16d can be directly absorbed by the liquid adsorption member 16j, and the risk of ink dripping can be greatly reduced.

[0038] Furthermore, the ink outlet portion 16 also includes a cap 16i, and the cap 16i is fixedly connected to the shell body 11. The connection method between the two can be, for example, snap-on, welding, or bonding. Along the ink flow direction, a part of the cap 16i is located downstream of the liquid adsorbent 16j, and along the radial direction of the ink outlet 16c, a part of the cap 16i is located on the outside of the liquid adsorbent 16j. Therefore, the liquid adsorbent 16j can be stably installed and can be effectively protected by the cap 16i. Even if the amount of ink adsorbed by the liquid adsorbent 16j is too much, the excess ink can be carried by the cap 16i and will not leak easily.

[0039] Furthermore, the ink outlet portion 16 also includes a sealing member 16k, and along the ink flow direction, the sealing member 16k is located upstream of the liquid adsorbent 16j. Generally, the liquid adsorbent 16j is made of a material with adsorption force. Preferably, the liquid adsorbent 16j is made of a porous flexible material. More preferably, the liquid adsorbent 16j is configured as a sponge, absorbent paper, etc., and the sealing member 16k is also an elastic member. In this way, the sealing effect between the sealing member 16k and the liquid adsorbent 16j will be effectively improved. At the same time, the liquid adsorbent 16j is clamped by the sealing member 16k and the cap 16i to become more stable.

[0040] [Example 2]

[0041] Figure 4 It is a three-dimensional diagram of the liquid absorbing material in the ink cartridge involved in the second embodiment of the utility model after being separated from the shell; Figure 5 After the ink cartridge involved in the second embodiment of the utility model is combined with the valve mechanism on the device side, Figure 1 A cross-sectional view taken in the direction indicated by line BB.

[0042] The difference between this embodiment and the above embodiment is that the cap 16i is omitted, the structure of the ink outlet portion 16 is simplified, and the liquid adsorbent 16j is arranged outside the ink outlet 16c, that is, the liquid adsorbent 16j is arranged adjacent to the ink outlet 16c, and along the ink flow direction, the liquid adsorbent 16j is located downstream of the ink outlet 16c, and along the radial direction of the ink outlet 16c, the liquid adsorbent 16j directly faces the ink outlet 16c. Similarly, the ink flow that has not entered the ink receiving chamber 21b1 can be absorbed by the liquid adsorbent 16j at the ink outlet 16c without dripping.

[0043] The liquid adsorbent 16j can be installed on the shell 11 by bonding, clamping, etc. Specifically, the liquid adsorbent 16j is installed on the lower surface 11b. Optionally, the liquid adsorbent 16j can also be installed in a mounting groove (not shown) preset on the shell 11.

[0044] When the ink cartridge 10 is combined with the device-side valve mechanism 22, the liquid adsorbing member 16j disposed downstream of the ink outlet 16c can also abut against the device-side valve mechanism 22 and be stably positioned on the housing 11. As described above, the liquid adsorbing member 16j is disposed so that, along the radial direction of the ink outlet 16c, the liquid adsorbing member 16j directly faces the ink outlet 16c, so that even if there is ink that does not enter the ink receiving chamber 21b1, the ink can be directly adsorbed by the liquid adsorbing member 16j, and finally, the risk of ink dripping can be effectively reduced.

[0046] Figure 6 The ink cartridge edge of the third embodiment of the utility model Figure 1 A cross-sectional view cut along the direction indicated by BB; Figure 7 and Figure 8 The ink cartridge edge of the third embodiment of the utility model Figure 1 A three-dimensional image after cutting in the direction shown in BB.

[0047] The difference between this embodiment and the above-mentioned embodiment lies in the structure of the ink outlet portion 16, which is as follows.

[0048] like Figure 6 , Figure 7 and Figure 8 As shown, the ink chamber 109 is divided into a first chamber 1091 and a second chamber 1092 by a partition 1094, and the first chamber 1091 and the second chamber 1092 are connected through a communication port 1095 on the partition 1094, wherein the second chamber 1092 is opposite to the ink outlet portion 16. The ink outlet portion 16 includes an ink outlet housing 16-1 and a push piece 16-2 that are combined with each other, and further, the ink outlet housing 16-1 and the push piece 16-2 are combined in a detachable manner; the ink outlet housing 16-1 is connected to the housing 11 and is formed with an ink outlet channel 16d that is connected with the second chamber 1092, and the push piece 16-2 includes a support plate 16a disposed in the ink outlet channel 16d and a top block 16b connected to the support plate 16a, and preferably, the support plate 16a is further provided with a through hole 16e, and the through hole 16e is used to connect the ink outlet channel 16d and the second chamber 1092.

[0049] The ink outlet channel 16d extends in the up-down direction. Preferably, the support plate 16a is arranged at the upper end of the ink outlet channel 16d, and the lower end of the ink outlet channel 16d forms an ink outlet 16c. Further, a negative pressure generating member 11k is arranged in the second chamber 1092, and the negative pressure generating member 11k is also in contact with the support plate 16a, so that before the device starts to absorb ink from the ink cartridge 10, the ink in the ink chamber 109 can be maintained by the negative pressure generating member 11k. Optionally, the negative pressure generating member 11k can be a sponge or made of other materials with adsorption capacity.

[0050] Further, such as Figure 7 and Figure 8 As shown, the ink outlet housing 16-1 and the pushing piece 16-2 can be combined by snapping, and the pushing piece 16-2 can be regarded as another force-applying piece. Specifically, the outer peripheral wall of the ink outlet housing 16-1 is provided with a snap-in portion 16m, and the snap-in portion 16m is provided with one or more, and the pushing piece 16-2 is provided with a buckle portion 16n combined with the snap-in portion 16m, and the buckle portion 16n is located on the side wall of the pushing piece 16-2 on the radial outer side of the ink outlet housing 16-1. Preferably, the snap-in portion 16m is a protrusion, and the buckle portion 16n is a groove or a through hole combined with the snap-in portion 16m. Optionally, the positions of the snap-in portion 16m and the buckle portion 16n are interchangeable. The push piece 16-2 is installed to the ink outlet housing 16-1 in the direction opposite to the ink flow direction, and the clamping portion 16m is first squeezed by the push piece 16-2 and then combined with the buckle portion 16n. Further, when the buckle portion 16n is a through hole, the clamping portion 16m will protrude from the buckle portion 16n. Further, when the clamping portion 16m is a protrusion, the clamping portion 16m radially protrudes from the outer side wall of the ink outlet housing 16-1. Preferably, the clamping portion 16m is elastic, so that the obstruction of the clamping portion 16m and the buckle portion 16n during assembly can be reduced, making the assembly smoother.

[0051] Furthermore, by combining the ink outlet housing 16-1 and the push member 16-2 in a detachable manner, the following beneficial effects can be obtained:

[0052] 1. On the one hand, the flexibility of replacing the pushing piece 16-2 can be improved. When it is necessary to adapt to other types of equipment, the pushing piece 16-2 can be disassembled and replaced, which greatly improves the versatility of the ink cartridge 10 and makes it more convenient to use. On the other hand, the scrap rate can be reduced. Compared with the non-detachable combination of the ink outlet shell 16-1 and the pushing piece 16-2, when the pushing piece 16-2 is worn after a long period of use, it can be directly replaced with a new pushing piece 16-2, and the shell 11 of the ink cartridge 10 can continue to be used. Therefore, the service life of the ink cartridge 10 can be extended, thereby reducing costs and achieving resource conservation.

[0053] 2. It can eliminate burrs caused by welding and the like, thereby ensuring the quality of the ink cartridge 10.

[0054] 3. When there is foreign matter inside the ink cartridge 10, it is easy to clean it, and it is convenient to check the condition of the ink cartridge 10 and any problems that may occur.

[0055] Fig.9A The ink cartridge of the third embodiment of the present invention is provided along the ink receiving portion of the device before being combined with the ink receiving portion of the device. Figure 1 A cross-sectional view cut along the direction indicated by BB; Fig. 9BThe ink cartridge of the third embodiment of the present invention is connected to the ink receiving part of the device and then Figure 1 A cross-sectional view taken in the direction indicated by line BB.

[0056] like Fig.9A As shown, the ink receiving portion 21 includes a first housing 21a and a second housing 21b connected to each other and a device side valve mechanism 22 arranged in the second housing 21b. The first housing 21a forms a temporary storage chamber 21a1 for receiving ink. Along the flow direction of the ink, the device side valve mechanism 22 is located upstream of the temporary storage chamber 21a1. The device side valve mechanism 22 includes a sealing body 221, a pushed member 223 connected to the sealing body 221, and a device side elastic member 222 abutting against the sealing body 221. The sealing body 221 is kept in a state of sealing the device side valve mechanism 22 under the forced pushing action of the device side elastic member 222. Further, the second housing 21b also includes a protruding housing 21b3 surrounding at least a part of the pushed member 223. The protruding housing 21b3 forms an ink receiving chamber 21b1. Along the flow direction of the ink, the ink receiving chamber 21b1 is located upstream of the sealing body 221.

[0057] When the ink cartridge 10 is installed Fig.9A In the state shown, the ink cartridge 10 is continued to be rotated backward and downward, and the ink outlet portion 16 is combined with the ink receiving portion 21. During the combination process, the ink receiving portion 21 enters the ink outlet channel 16d from the ink outlet port 16c, and the top block 16b begins to abut against the pushed member 223. As the ink cartridge 10 is further rotated, the elastic force of the device-side elastic member 222 is overcome, and the sealing body 221 begins to move toward the temporary storage chamber 21a1 through the pushed member 223. The valve mechanism 22 on the device side is gradually opened, and the ink receiving chamber 21b1 enters the ink outlet channel 16d. At this time, the ink cartridge 10 reaches the predetermined installation position (such as Fig. 9B shown).

[0058] When the device absorbs ink from the ink outlet channel 16d through the ink receiving portion 21, the ink absorbed by the negative pressure generating member 11k enters the ink outlet channel 16d through the through hole 16e, then enters the ink receiving chamber 21b1, and finally, the ink flows into the temporary storage chamber 21a1. When the ink cartridge 10 rotates toward the front and upper direction, the top block 16b gradually disengages from the abutment with the pushed member 223, and under the elastic force of the device-side elastic member 222, the sealing body 221 gradually seals the device-side valve mechanism 22 again.

[0059] In this embodiment, the ink outlet portion 16 does not need to be provided with a valve mechanism, but the negative pressure generating member 11k keeps the ink in the second chamber 1092. It can be seen that the structure of the ink cartridge 10 / ink outlet portion 16 is simplified, and thus, the matching accuracy between the components can be reduced. In some embodiments, the ink outlet portion 16 is provided with a valve mechanism, in which case the through hole 16e may not be provided.

[0060] In some embodiments, in order to enable the ink to be better retained in the ink chamber 109 by the negative pressure generating element 11k, the ink chamber 109 also includes a third chamber 1093 arranged between the second chamber 1092 and the ink outlet portion 16, and the third chamber 1093 is connected to the ink outlet channel 16d. Preferably, along the direction intersecting with the up and down directions, the size of the third chamber 1093 is smaller than the size of the second chamber 1092, and the negative pressure generating element 11k is also installed in the third chamber 1093. In this way, the negative pressure generating element 11k located in the third chamber 1093 only needs to be able to absorb the ink to prevent the ink from dripping from the ink outlet portion 16.

[0063] The difference between this embodiment and the third embodiment lies in the combination mode of the ink outlet housing 16-1 and the push member 16-2. Specifically, Fig.10 and Fig.11 As shown, the ink outlet housing 16-1 and the push piece 16-2 can be rotatably combined, for example, threaded connection, specifically, the outer peripheral wall of the ink outlet housing 16-1 is provided with an external thread 16p, and the push piece 16-2 is provided with an internal thread 16q adapted to the external thread 16p. The push piece 16-2 is screwed to the ink outlet housing 16-1 in the direction opposite to the ink flow direction, so that the assembly is smooth. This embodiment can also obtain the same beneficial effects as the third embodiment, so it is not repeated here.

[0064] As described above, combining the ink outlet housing 16-1 and the push piece 16-2 in a detachable manner can not only eliminate quality problems such as burrs, but also improve the flexibility of replacing the push piece 16-2 and the adaptability of the ink cartridge 10, and can also extend the service life of the ink cartridge 10, thereby reducing costs.
