[0005] This utility model aims to provide an ink storage unit with a simple structure.

[0006] To achieve the above object, in the first aspect of this utility model, an ink storage unit is provided, which includes an ink sac for storing ink and an adapter installed at the front end of the ink sac. The installation direction of the ink storage unit into the inkjet printer is parallel to the length direction of the ink storage unit.

[0007] The ink delivery channel includes an ink delivery pipe extending into the ink sac.

[0008] The inner side of the ink delivery pipe is provided with a trapping device extending in a single direction.

[0009] The trapping device extends in a direction opposite to the direction of gravity, and the trapping device is separately provided from the ink delivery pipe.

[0010] Furthermore, the trapping device is a flat plate forming an angle with the axis of the ink delivery pipe.

[0011] Furthermore, the trapping device is fixed in the ink delivery pipe by interference fit, bonding, welding or snap fit.

[0012] Further, it further includes a keel, and the number of the trapping devices is set to be multiple; the multiple trapping devices are arranged on the keel.

[0013] Further, a second fixing portion corresponding to the first fixing portion is provided on the trapping device and / or the keel, and through the cooperation of the first fixing portion and the second fixing portion, the trapping device and the keel are installed in the ink delivery pipe.

[0014] It can be seen that for the ink storage unit provided in the first aspect of the present invention, the trapping device only extends upward from bottom to top, without extending downward from top to bottom, which is beneficial to simplifying the shape structure of the ink delivery pipe. At the same time, by separately arranging the trapping device and the ink delivery pipe, there is no need to integrally form the trapping devices extending from bottom to top and from top to bottom in the pipe at one time, simplifying the mold and reducing the production cost. Compared with the background technology solution, under the condition of ensuring equivalent ink delivery resistance, the interception mechanism of this solution is only composed of the trapping device extending from bottom to top. The trapping device can obtain a greater interception height, collect more foreign matters, extend the service life of the ink storage unit, and increase the renewable times.

[0015] The second aspect of the present invention further provides an ink storage unit, including an ink sac for storing ink and an adapter installed at the front end of the ink sac. Along the installation direction of the ink storage unit into the inkjet printer, it is parallel to the length direction of the ink storage unit. The ink delivery channel includes an ink delivery pipe extending into the ink sac; the ink delivery pipe is a serpentine curved pipe with undulations up and down.

[0016] Further, the serpentine curved pipe includes a longitudinal section and a transverse section; along the direction opposite to gravity, the transverse section includes a lower transverse section located on the lower side and an upper transverse section located on the upper side; along the flow direction of the ink discharge, the longitudinal section includes an upward section and a downward section, wherein the upward section serves as the trapping device.

[0017] Further, the axis of the upward section forms an angle with the installation direction, and along the installation direction, the upward section inclines backward.

[0018] It can be seen that for the ink storage unit provided in the second aspect of the present invention, by setting the ink delivery pipe as a serpentine curved pipe, the upward section of the undulating ink delivery pipe itself serves as the trapping device, thus eliminating the need to further provide a trapping device on the inner wall of the ink delivery pipe, simplifying the mold, reducing the production cost, and at the same time ensuring the performance of trapping ink foreign matters.

[0019] In a third aspect of the present utility model, an ink storage unit is provided, which includes an ink sac for storing ink and an adapter installed at the front end of the ink sac. The installation direction of the ink storage unit into the inkjet printer is parallel to the length direction of the ink storage unit. The ink delivery channel includes an ink delivery pipe extending into the ink sac. Along the installation direction, inverted U-shaped grooves are respectively provided on the upper side and the lower side in the ink delivery channel.

[0020] It can be seen that for the ink storage unit provided in the third aspect of the present utility model, foreign matters in the ink can be collected through the U-shaped grooves provided in the ink delivery pipe.

[0021] In a fourth aspect of the present utility model, an ink storage unit is provided, which includes an ink sac for storing ink and an adapter installed at the front end of the ink sac.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0033] Since the density of the foreign matter is greater than the density of the ink, the foreign matter has a tendency to settle in the ink.

[0034] In all the following embodiments, the width direction 02 of the ink storage unit is the width direction of the carrier box, the length direction 01 of the ink storage unit is the length direction of the carrier box, and the installation direction 04 along which the ink storage unit is installed in the inkjet printer is parallel to the length direction 01. The direction 03 opposite to the gravity is parallel to the height direction of the ink storage unit.

[0035] Embodiment 1

[0036] As Figure 1 and Figure 2 shown, the ink storage unit 100 includes an ink sac 110 for storing ink and an adapter 120 installed at the front end of the ink sac 110. The installation direction 04 along which the ink storage unit 100 is installed in the inkjet printer (not shown in the figure) is parallel to the length direction 01 of the ink storage unit.

[0037] The ink delivery channel 121 includes an ink delivery pipe 122 extending into the ink sac 110.

[0038] A trapping device 123 extending in a single direction is provided inside the ink delivery pipe 122.

[0039] The trapping device 123 extends along the direction 03 opposite to the gravity.

[0040] It can be seen that the trapping device 123 only extends from bottom to top and does not need to extend from top to bottom, which is beneficial to simplifying the shape structure of the ink delivery pipe 122, simplifying the mold, and reducing the production cost. Compared with the background technology solution, under the condition of ensuring that the ink delivery resistance is equivalent, this solution only consists of the trapping device 123 extending from bottom to top to form an interception mechanism. The trapping device 123 can obtain a larger interception height, collect more foreign matters, extend the service life of the ink storage unit 100, and increase the number of renewable times.

[0041] Preferably, the trapping device 123 is a flat plate arranged vertically. Further, the trapping device 123 is a flat plate perpendicular to the axis of the ink delivery pipe 122.

[0042] In other embodiments, the trapping device 123 is a flat plate forming an angle with the axis of the ink delivery pipe 122. Specifically, the trapping device 123 can also be set to incline towards the length direction 01, that is to say, the trapping device 123 can incline towards the installation direction 04 or towards the direction opposite to the installation direction 04.

[0043] The shape of the trapping device 123 is not limited to a flat plate shape, and can also be a tile shape or a curved panel of other shapes, or a grid.

[0044] Preferably, the number of the trapping devices 123 is not limited to one, and can also be two, three or more.

[0045] Preferably, the trapping device 123 and the ink delivery pipe 122 are integrally formed.

[0046] Embodiment 2

[0047] See Figure 3 and Figure 4 In this embodiment, the difference from Embodiment 1 lies in the installation method of the trapping device 223. The trapping device 223 is fixed on the keel 224, and the trapping device 223 and the keel 224 are loaded into the ink delivery pipe 222 together. For example, the trapping device 223 and the keel 224 are inserted into the ink delivery pipe 222 from the end far away from the adapter 220 together.

[0048] Preferably, the trapping device 223 is fixed in the ink delivery pipe 222 by interference fit, bonding or welding. Optionally, the trapping device 223 is fixed by a snap-fit method, which can be specifically realized by the cooperation of a first fixing part and a second fixing part; for example, a first fixing part (not shown in the figure) is provided on one side of the ink delivery pipe 222 located inside the ink sac, and the trapping device 223 and / or the keel 224 are provided with a second fixing part corresponding to the first fixing part. Through the cooperation of the first fixing part and the second fixing part, the trapping device 223 and the keel 224 are installed in the ink delivery pipe 222. In other words, the first fixing part and the second fixing part play a role in guiding and fixing the installation of the trapping part. For the positions where the first fixing part and the second fixing part are arranged, they can be either on the inner side of the ink delivery pipe 222 or on the outer side of the ink delivery pipe 222; it can be understood that the first fixing part and the second fixing part can also be arranged on the inner wall of the ink sac. There is no limitation on the specific structures of the first fixing part and the second fixing part, and common snap-fit methods in the prior art can be adopted.

[0049] Preferably, the ink delivery pipe 222 and the frame 225 of the adapter 220 are integrally formed.

[0050] This embodiment further simplifies the forming process of the ink delivery pipe 222 and the trapping device 223, simplifies the mold, further reduces the production cost, and improves the practicability.

[0051] Embodiment 3

[0052] As Figure 5As shown, the ink storage unit 300 includes an ink sac 310 for storing ink and an adapter 320 installed at the front end of the ink sac 310.

[0056] Along the ink discharge flow direction 05, the longitudinal section 323 includes an upward section 3231 and a downward section 3232, where the upward section 3231 serves as a trapping device.

[0057] Compared with Embodiment 1, there are no foreign object protrusions in the ink delivery pipe 322 of this embodiment, and it has a smaller ink delivery resistance. The ink delivery pipe 322 is easy to mold, and the manufacturing cost is further reduced. Preferably, the ink delivery pipe 322 is formed by blow molding. The ink delivery pipe 322 can be fixed to the frame 325 of the adapter 320 by interference fit, bonding, welding or other means. Obviously, the ink delivery pipe 322 can be integrally formed with the adapter 320 or independently blow molded.

[0058] Embodiment 4

[0059] As Figure 6 shown, the difference between this embodiment and Embodiment 3 lies in the shape of the ink delivery pipe 422. The axis 4230 of the upward section 4231 forms an angle with the installation direction 04, and along the installation direction 04, the upward section 4231 tilts backward. This solution is beneficial for retaining foreign objects in the ink delivery pipe 422.

[0060] Preferably, the lower transverse section 4241 and the upper transverse section 4242 are arc-shaped, which is beneficial for reducing the ink delivery resistance and depositing foreign objects on the lower side of the lower transverse section 4241 by centrifugal force.

[0069] The ink supply channel 621 includes an ink supply pipe 622 extending into the ink sac 610.

[0070] A filter membrane 623 is provided on the side of the ink supply channel 621 away from the ink sac 610.

[0071] The filter membrane 623 can effectively intercept foreign matter in the ink supply channel 621, with a simple structure and low cost.

[0072] In other embodiments, the filter membrane 623 can also be provided on the side of the ink supply pipe 622 away from the frame 625 of the adapter 620, preferably on the end face 624. In this way, foreign matter can be intercepted in the ink sac 610 to prevent foreign matter from blocking the ink supply channel 621. As long as the ink sac 610 is shaken, the ink in the ink sac 610 can be used to wash the filter membrane on the end face 624 to prevent the filter screen from being blocked.
