[0039] Example 1

[0040] An ink replenishing system comprises an ink tank and an ink replenishing container. Ink in the ink replenishing container can be replenished into the ink tank for printing on a recording medium.

[0041] An inkjet printer (not shown) is equipped with an ink tank that holds ink. This tank is connected to the printer's ink tube, allowing ink to be supplied from the tank to the printer's print head, thereby performing inkjet printing on a recording medium (e.g., paper). The ink tank can be located externally or internally within the inkjet printer. There can be one or more ink tanks, and multiple ink tanks can be arranged in a widthwise arrangement. Multiple ink tanks can each hold inks of different colors, for example, black ink, yellow ink, magenta ink, and cyan ink, respectively. Alternatively, multiple ink tanks can hold ink of the same color.

[0042] like Figure 1 and Figure 2 As shown, the ink tank is provided with an ink inlet flow path portion 1 with an ink supply needle 3. The ink inlet flow path portion 1 has a recess 2 formed on the top of the ink tank. The ink supply needle 3 is protruded outward from the recess 2. It can be higher than the top surface of the recess 2 or lower than the bottom surface of the recess 2. The ink supply needle 3 is connected to the internal space of the ink tank, as shown in FIG. Figure 2 As shown, the ink supply needle 3 has two flow paths, one of which is the ink flow path, and the other is the air flow path. The two flow paths are respectively connected to the internal space of the ink tank. Specifically, the two flow paths are the first flow path 3b and the second flow path 3c. If the first flow path 3b is the ink flow path, the second flow path 3c is the air flow path; and the two flow paths are separated by a partition component 3a, and the top end of the partition component 3a is protruding and is higher than the top surface of the two flow paths.

[0043] Furthermore, if Figure 2 、 Figure 4 As shown, the spacing component 3a of the ink supply needle 3 is composed of a partition wall and a cylindrical portion. The partition wall is connected to the inner circumferential wall of the ink supply needle. The cylindrical portion is arranged between the two partition walls and is respectively connected to the two partition walls. The top of the cylindrical portion is open and the bottom is closed. A hollow space 3d is formed between the top and the bottom. The space 3d includes a large cylindrical portion 3d2 and a small cylindrical portion 3d1. The large cylindrical portion 3d2 is located above the small cylindrical portion 3d1, that is, the large cylindrical portion 3d2 is closer to the top opening.

[0044] like Figure 2 、 Figure 3As shown, the ink inlet flow path portion 1 is further provided with a support member 4. The support member 4 is disposed within the space 3d within the ink supply needle 3. The support member 4 includes a large diameter portion 4b and a small diameter portion 4a. When the support member 4 is accommodated within the internal space 3d of the ink supply needle 3, the small diameter portion 4a engages with the small cylindrical portion 3d1, where the engagement can be an interference fit. The large diameter portion 4b engages with the large cylindrical portion 3d2, where the engagement can be either an interference fit or a non-interference fit. The top of the large diameter portion 4b can be configured in a needle shape. The top of the large diameter portion 4a can be higher than the top of the partition member 3a or can be flush with the top of the partition member 3a. Preferably, the top of the large diameter portion 4a is higher than the top of the partition member 3a.

[0045] Furthermore, if Figure 1 、 Figure 2 As shown, the inner circumferential wall of the recess 2 is provided with a first engaging portion 5. The first engaging portion 5 protrudes from the inner circumferential wall of the recess and can be in the form of a protrusion, a bump, or a rib. In other embodiments, the first engaging portion 5 can also be recessed into the inner circumferential wall to form an annular groove. In this embodiment, the first engaging portion 5 is positioned differently on ink tanks of different colors to facilitate identification of filling. The number of first engaging portions 5 is not fixed and can be one or more.

[0046] like Figure 5-10 As shown, an ink refill container 100 for refilling ink into the above ink tank is shown. The ink refill container 100 includes a container body 110, an ink outlet flow path 120, and a cover member 130. The ink refill container 100 can be an ink bottle, an ink bag, an ink tank, etc.; an ink bottle is used as an example of the ink refill container 100 for description.

[0047] The container body 110 has a storage space inside for storing ink. Taking the ink bottle as an example, the container body 110 is the bottle body 110. The bottle body 110 is generally cylindrical, but can also be other shapes such as a quadrangular prism. The bottle body 110 can be made of a flexible material that can be squeezed and deformed, or it can be made of other materials that cannot be squeezed and deformed. Figure 6 As described above, one end of the bottle body 110 has an open end, the diameter of the open end is smaller than the diameter of the bottle body, and an opening 111 is provided at the end of the open end away from the bottle body, and the ink in the bottle body flows out through the opening 111.

[0048] The ink outlet flow path 120 is provided at the open end of the container body 110 (bottle body 110 ) and is connected to the container body 110 through the opening 111 . The ink in the container body 110 flows out through the ink outlet flow path 120 . Figure 6-Figure 8As shown, the ink outlet flow path portion 120 includes a first connection portion 120a and an ink outflow portion 120b. The first connection portion 120a is closer to the container body 110 than the ink outflow portion 120b. The first connection portion 120a is connected to the open end of the container body 110. Specifically, an internal thread 124 is provided within the first connection portion 120a, and an external thread 132 is provided on the outer peripheral wall of the open end of the container body 110. The first connection portion 120a and the container body 110 are screwed together by the internal thread 124 and the external thread 132. Alternatively, the ink outlet flow path portion 120 and the container body 110 may be connected by snap-fit ​​connection, adhesive bonding, welding (spot welding), etc., in addition to being threaded, or may be an integrally molded structure.

[0049] The ink outflow portion 120 b is tubular, and the interior of the ink outflow portion 120 b is an ink channel connected to the container main body 110 . The ink outflow portion 120 b is provided with an ink outlet 121 at one end away from the container main body 110 .

[0050] like Figure 8 As shown, in this embodiment, in order to enable the ink replenishing container 100 to be correctly connected to the ink inlet flow path portion 1 on the ink tank, a first engaged portion 123 is provided on the outer peripheral wall of the ink outflow portion 120b near the ink outlet 121. The first engaged portion 123 is a recessed portion formed by inward depression on the outer peripheral wall, which can be identified and connected with the first engaging portion 5 in the ink inlet flow path portion 1. The shape and number of the first engaged portion 123 can be set according to the shape and number of the first engaging portion 5 in the ink tank, as long as the identification connection between the two is satisfied.

[0051] like Figure 6 、 Figure 7 As shown, the valve component 140 is arranged in the ink outflow portion 120b to open or close the ink outlet. Specifically, the valve component 140 is arranged close to the ink outlet 121. The valve component 140 is elastic and can rely on its own elasticity to seal the ink outlet 121. The valve component 140 can be cylindrical, and its outer diameter can be equal to or slightly larger than the inner diameter of the ink outflow portion 120b, so that when the valve component 140 is installed in the ink outflow portion 120b, it can fit tightly with the inner wall of the ink outflow portion 120b, thereby forming a seal for the ink outlet 121. A valve plate is also provided at the end of the valve component 140 away from the ink outlet. The valve plate can be integrally formed with the valve component 140. A self-closing incision is provided on the valve plate. The self-closing incision can be Y-shaped, straight-shaped, cross-shaped or "*"-shaped. In the absence of external force, the self-closing incision is in a closed state under the action of its own elasticity, so that the valve component 140 can close and seal the ink outlet 121, and the ink in the ink replenishing container 100 cannot flow out.

[0052] Further, such as Figure 9As shown, in order to prevent the valve component 140 from moving when subjected to force, a clamping portion 125 is further provided on the inner wall of the ink outflow portion 120b, which is installed in cooperation with the valve component 140, and a joint portion (not shown in the figure) that cooperates with the clamping portion 125 is provided on the circumferential outer wall of the valve component 140. Preferably, the clamping portion 125 is a flange formed on the inner wall of the ink outflow portion 120b, and the flange extends along the circumference of the ink outflow portion 120b. The joint portion is an annular groove provided along the circumference of the valve component 140. During installation, force is applied to deform the valve component 140, so that the flange is stuck in the annular groove, thereby limiting the axial movement of the valve component 140 and preventing it from falling out / falling into the ink outflow portion 120b when subjected to force.

[0053] like Figures 8 to 10 As shown, the ink outlet forming portion 120 is further provided with a positioning member 160. The positioning member 160 is fixedly disposed within the ink outlet forming portion 120. The positioning member 160 extends at least partially in a direction parallel to the central axis of the ink outlet 121. A positioning portion 162 is provided at one end of the positioning member 160 near the ink outlet 121. The positioning portion 162 has a positioning surface 162a formed thereon. An annular protrusion 161 is provided protrudingly around the positioning portion 162. The annular protrusion 161 is located farther from the container body 110 along the central axis of the ink outlet than the positioning portion 162. The annular protrusions 161 are spaced apart from each other, and may also be provided in a number of three, four, or more. Furthermore, the annular protrusions 161 are provided with guide surfaces 161a. The guide surfaces 161a extend obliquely from the end of the annular protrusion 161 near the ink outlet toward the central axis of the ink outlet. The guide surfaces 161a are connected to the positioning surfaces 162a on the positioning portion 162.

[0054] Furthermore, the ink outlet forming portion 120 further includes a support column 170 for supporting and securing the positioning member 160. The support column 170 is at least partially located on and extends along the central axis of the ink outlet 121. The positioning member 160 is fixedly disposed at one end of the support column 170 away from the container body 110. A fixing portion 180 is provided at the end of the support column 170 near the container body. One end of the fixing portion 180 is connected to the support column 170, and the other end is connected to the inner wall of the ink outlet forming portion 120. The other end of the fixing portion 180 extends along the central axis toward the ink outlet. When viewed along the central axis of the ink outlet, the other end of the fixing portion 180 protrudes from the inner wall of the ink outlet forming portion 120 and may be in the form of a rib, rib, or bump. The support column 170 secures the positioning member 160 to the central axis of the ink outlet forming portion 120. Preferably, the support column 170 , the fixing portion 180 and the positioning component 160 are an integrally formed structure. More preferably, the support column 170 , the fixing portion 180 , the positioning component 160 and the ink outlet forming portion 120 are all an integrally formed structure.

[0055] like Figure 8 As shown, the shape of the positioning component 160 can be Y-shaped, cross-shaped, straight-line, triangular or *-shaped, or other regular or irregular geometric shapes or combined shapes. This embodiment does not limit the shape of the positioning component 160, as long as it can guide the support member 4 to stably abut against it.

[0056] like Figure 10 As shown, when the ink refill container is inserted upside down into the ink tank, that is, the ink outlet forming portion 120 is engaged with the ink inlet flow path portion 1, the ink supply needle 3 opens the valve component 140 and is inserted into the ink outlet forming portion 120, and the top end portion of the support member 4 on the ink supply needle 3 abuts against the positioning surface 162a.

[0057] like Figures 1 to 10 As shown, when using the ink replenishing container 100 to replenish the ink tank with ink, the ink replenishing container 100 is turned upside down, and then the ink replenishing container 100 is aligned with the ink inlet flow path portion 1 and inserted. The first clamping portion 123 on the ink outlet flow path portion 120 cooperates with the first clamping portion 5 in the ink inlet flow path portion 1, so that the first clamping portion 5 is inserted into the first clamping portion 123. At this time, the ink supply needle 3 contacts and squeezes the valve plate of the valve component 140, causing the self-closing incision to elastically deform, and the ink supply needle 3 passes through the valve plate and is inserted into the ink outlet forming portion 120. The support on the ink supply needle 3 The top end of the component 4 is guided by the guide surface 161a and abuts against the positioning surface 162a on the positioning portion 162. The movement of the ink replenishing container 100 relative to the ink tank is restricted, and it cannot be further inserted into the recessed portion 2 of the ink inlet flow path portion 1. The position of the ink supply needle 3 in the ink outlet forming portion 120 is also limited, thereby guiding the correct positioning of the ink replenishing container 100 and the ink tank. At the same time, it can also automatically correct the positional relationship between the ink replenishing container and the ink tank to prevent unstable positioning between the two, affect the ink filling speed, and prevent ink leakage.

[0058] Furthermore, at least a portion of the ink supply needle 3 is positioned outside the ink outlet 121. A certain distance exists between the end of the ink outlet-forming portion 120 near the ink outlet 121 and the bottom surface of the recess 2. This prevents contamination of the ink refill container 100 by ink remaining around the ink supply needle 3 or at the bottom of the recess during filling. Once the ink supply needle 3 is inserted into the ink outlet-forming portion 120, it connects the container body 110 of the ink refill container 100 with the ink chamber within the ink tank. Ink in the container body 110 is then refilled into the ink tank via the ink supply needle 3. Once refilling is complete, the ink refill container 100 is removed from the ink tank. The valve member 140, with its elasticity, seals and closes the ink outlet 121.

[0059] Furthermore, the ink refill container 10 may further include a cover member 130, which is detachably covered on the ink outlet flow path portion 120 to shield the ink outflow portion and play a protective role. Figure 7 As shown, an internal thread 131 is provided on the inner peripheral wall of the cover part 130, which can be threadedly connected to the external thread 122 on the ink outlet forming part 120. The cover part 130 can be disassembled relative to the ink outlet forming part 120, and the cover part 130 and the ink outlet forming part 120 can be connected by threaded engagement or by snap-fitting engagement.

[0060] Furthermore, a protrusion 132 is provided inside the top end portion of the cover member 130, which extends from the inner side of the top end portion of the cover member 130 toward away from the top end portion. When the cover member 130 is covered on the ink outlet forming portion 120, at least a portion of the protrusion 132 is accommodated in the opening space of the valve member 130 toward the ink outlet, occupying the spatial area of ​​the valve member 130, thereby further preventing ink leakage.

[0061] In some other embodiments, the ink refill container 100 may not be provided with a cover component, but a sealing film may be provided at the ink outlet to block the ink outlet, thereby further achieving a sealing effect.

[0062] In some other embodiments, the ink refill container 100 may be provided with both a cover component and a sealing film.

[0063] Example 2

[0064] The difference between this embodiment and the first embodiment is that a limiting portion 290 is further provided in the ink outlet forming portion.

[0065] Specifically, if Figure 11 、 Figure 12 As shown, the limiting portion 290 is arranged on the outside of the fixing portion 280, that is, it is arranged closer to the support column than the fixing portion 280. The shape of the limiting portion 290 is similar to that of the fixing portion 280, that is, it extends in the direction of the central axis of the ink outlet, and its length can be less than or equal to the length of the fixing portion 280. When viewed from the direction of the central axis of the ink outlet, the limiting portion 290 protrudes from the fixing portion 280, and its shape can be a convex rib, a convex tendon or a bump.

[0066] Furthermore, if Figure 12 As shown, the limiting portion 290 is provided with a guide surface 291 at one end facing the ink outlet, and the guide surface 291 extends obliquely along the direction of the central axis of the ink outlet toward and away from the ink outlet; the limiting portion 290 is also provided with an abutment surface 292, which is parallel to the central axis of the ink outlet and is connected to the end of the guide surface 291 away from the ink outlet.

[0067] like Figure 13 As shown, when filling ink, the ink supply needle 30 is inserted into the ink outlet forming part. Under the guidance of the guide surface 291 of the limiting part 290, its outer peripheral wall can abut against the abutment surface 292, or there can be a certain gap between the abutment surface 292, thereby limiting the movement of the ink supply needle 30 in the ink outlet forming part, that is, limiting the movement in the radial direction of the central axis of the ink outlet.

[0068] In some other embodiments, the guide surface on the limiting portion 290 may not be provided, and it is sufficient to ensure that the ink supply needle can enter and limit easily.

[0069] In this embodiment, the limiting portion 290 and the fixing portion 282 are integrally provided, but in some other embodiments, the limiting portion and the fixing portion may also be separately provided. If they are separately provided, the two may be connected by snapping, bonding, welding, or the like.

[0070] The other structures of the ink tank and ink refill container of this embodiment are the same as those of the first embodiment and will not be described again here.

[0071] Example 3

[0072] Based on the second embodiment, Figure 13 As shown, the top end of the ink supply needle 30 can also be set to a plane 31. In this case, the top plane on the ink supply needle abuts against the annular protrusion on the positioning component, which facilitates the filling of ink.

[0073] Example 4

[0074] The difference between this embodiment and the first embodiment lies in that the shape of the spacer component on the ink supply needle in the ink tank and the connection relationship between the spacer component and the support component are different.

[0075] Modification 1

[0076] like Figure 14 As shown, different from the first embodiment, a semi-cylindrical portion is provided on the spacing member 3a1 in this embodiment, and the semi-cylindrical portion is only provided on the left side, and the right side is open.

[0077] like Figure 15 As shown, the support member 4a is fixedly connected to the spacing member 3a1, that is, the spacer member 3a1 is a member that protrudes directly from the bottom of the semi-cylindrical portion.

[0078] The other structures are the same as those in the first embodiment and will not be described again here.

[0079] Modification 2

[0080] like Figure 16 As shown, the semi-cylindrical portion on the spacer member 3a2 may also be provided only on the right side, with the left side portion being open.

[0081] like Figure 17 As shown, the support member 4b is fixedly connected to the spacing member 3a2, that is, the spacer member 3a2 is a member that protrudes directly from the bottom of the semi-cylindrical portion.

[0082] The other structures are the same as those in the first embodiment and will not be described again here.

[0083] Modification 3

[0084] like Figure 18 、 19 As shown, the spacer is formed by two partition walls 3a3, and a groove 3e is formed between the two partition walls 3a3, and the support member 4c protrudes from the middle position of the groove 3e. In this modified example, the support member 4c is fixedly connected to the groove 3e, that is, it is a component that directly protrudes from the bottom of the groove.
