[0033] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as limiting the present utility model.

[0034] Referring to Figures 1 to 10 as shown, the present utility model provides an ink replenishment container, including a container main body part 10, an ink outlet forming part 20, and a flow - creating pipe body 30, wherein:

[0035] The container main body part 10 is used for storing ink. The ink outlet forming part 20 is connected to the container main body part 10. The ink outlet forming part 20 has an ink outlet 21, and the ink in the container main body part 10 can flow out through the ink outlet 21 via the ink outlet forming part 20.

[0036] When filling ink, air bubbles may be generated during the filling process of the ink in the ink bottle, resulting in a slow filling speed. To solve this problem, the flow - creating tube body 30 is disposed in the container main body portion 10 and / or the ink outlet forming portion 20. When the ink in the container main body portion 10 enters the flow - creating tube body 30, the flow direction of the ink does not extend along the axis direction of the flow - creating tube body 30, but at least part of the flow direction of the ink intersects with the axis direction of the flow - creating tube body 30, causing the ink to rotate and generate a vortex in the flow - creating tube body 30, thereby eliminating air bubbles and accelerating the flow of the ink, so that the ink can flow out quickly from the ink outlet 21, thus improving the filling efficiency.

[0037] In the embodiment provided by the present application, the flow - creating tube body 30 is disposed at the outlet of the container main body portion 10, and the ink can be accelerated when flowing out from the container main body portion 10, which is beneficial to improving the filling efficiency. In other embodiments, the flow - creating tube body 30 can be disposed in the ink outlet forming portion 20, or the flow - creating tube body 30 can be disposed in both the container main body portion 10 and the ink outlet forming portion 20. It can also be disposed at the connection between the container main body portion 10 and the ink outlet forming portion 20, that is, part of it is located in the container main body portion 10 and the other part is located in the ink outlet forming portion 20. The number and position of the flow - creating tube body 30 can be set accordingly according to the structure and volume of the ink supply container, and are not limited herein.

[0038] Refer to Figures 5 to 7 As shown, the flow - creating tube body 30 has a flow - creating portion 31 inside. One end of the flow - creating portion 31 is communicated with the container main body portion 10, and the other end of the flow - creating portion 31 is communicated with the ink outlet 21. At least one first ink flow channel 33 is formed in the flow - creating portion 31. At least part of the extending direction of the first ink flow channel 33 forms a preset angle 35 with the axis direction of the flow - creating tube body 30, that is, the first ink flow channel 33 is formed in the flow - creating portion 31 in an inclined manner. Thus, after the ink enters the flow - creating portion 31, it rotates when passing through the first ink flow channel 33, and the air bubbles will collide with the wall surface of the first ink flow channel 33 and dissipate.

[0039] Whether the preset angle 35 is too large or too small has little impact on the improvement of the ink flow rate. Therefore, a suitable angle needs to be selected for setting. The optimal range of the preset angle 35 is 30 - 60°, and it can be set according to the capacity of the flow - creating portion 31 to make the ink flow rate reach the optimum.

[0040] Further, there is also a second ink flow channel 34 in the axis direction of the flow - creating tube body 30. The second ink flow channel 34 is offset from the flow - creating portion 31. Refer to Figure 4 And Figure 6As shown, the second ink flow channel 34 is a channel on the axis of the flow generating pipe body 30. The first ink flow channel 33 is connected to the second ink flow channel 34. A part of the ink rotates through the first ink flow channel 33, and a part of the ink flows through the second ink flow channel 34. Then, the two parts of the ink are mixed to generate a vortex, further eliminating air bubbles and increasing the flow rate.

[0041] In a feasible embodiment, the flow generating part 31 includes a flow generating member 32. One end of the flow generating member 32 is connected to the inner wall surface of the flow generating part 31, and the other end of the flow generating member 32 is suspended. Along the axial direction of the flow generating pipe body 30, the flow generating member 32 extends in a spiral shape. Due to the spiral shape of the flow generating member 32, when the ink passes through the flow generating member 32 (i.e., the ink flows through the first ink flow channel 33), it can be guided to move along the extending direction of the flow generating member 32. A part of the air bubbles will collide with the inner wall of the flow generating member 32 and dissipate, accelerating the flow rate of the ink.

[0042] In order to enable the ink to continuously rotate and maintain an accelerating state, in the embodiments provided in the present application, a plurality of flow generating members 32 are provided. The plurality of flow generating members 32 are annularly spaced with the axis of the flow generating pipe body 30 as the center, thereby forming a plurality of first ink flow channels 33. The plurality of first ink flow channels 33 are annularly spaced with the axis of the flow generating pipe body 30 as the center, so as to realize the continuous rotation of the ink in the flow generating pipe body 30 to dissipate air bubbles.

[0043] Those skilled in the art can know that only one flow generating member 32 can also be provided in the flow generating part 31. In this case, the flow generating member 32 is an integral component, which is formed by a continuous sheet spirally extending along the axial direction of the flow generating part 31.

[0044] In a feasible embodiment, along the axial direction of the flow generating pipe body 30, there is an overlapping part between adjacent flow generating members 32, so that adjacent first ink flow channels 33 can be connected, reducing the disordered flow of the ink. And there is a height difference between the plurality of flow generating members 32, so that the ink can continuously rotate and flow in the connected plurality of first ink flow channels 33. The air bubbles are collided and dissipated during the flow process, and the flow rate of the ink is also increased.

[0045] Preferably, the flow generating member 32 is a spiral blade. The plurality of spiral blades are spaced on the inner peripheral wall of the flow generating part 31. One end of the spiral blade is connected to the inner wall surface of the flow generating part 31, and the other end of the spiral blade is suspended. Due to the structural characteristics of the spiral blade, when the ink flows through the flow generating pipe body 30, under the combined action of the plurality of first ink flow channels 33 formed by the plurality of spiral blades, it is mixed with the ink flowing out from the second ink flow channel 34 at the center of the flow generating pipe body 30 to generate a vortex during the continuous flow process. Coupled with the action of the self-gravity of the ink, the ink can flow out at a relatively fast speed, avoiding the problem of slow flow rate caused by the generation of air bubbles.

[0046] In other embodiments, the flow generating member 32 may adopt other structures or components capable of forming a plurality of first ink flow channels 33, which are not limited herein.

[0047] In other embodiments, only a plurality of first ink flow channels 33 may be provided in the flow generating tube body 30, and the second ink flow channels 34 may not be provided.

[0048] Before filling the ink replenishing container of the present application, the ink outlet 21 needs to be closed to prevent ink leakage. Refer to Figures 1 to 4 As shown, the ink replenishing container further includes a cover member 40. The cover member 40 can be covered on the ink outlet forming portion 20. When the cover member 40 is covered on the ink outlet forming portion 20, the ink outlet 21 is located inside the cover member 40 and is closed by the cover member 40, and the ink cannot flow out from the ink outlet 21.

[0049] To save costs, a sealing film may also be provided at the ink outlet 21, the cover member 40 may be cancelled, and the ink outlet 21 is sealed by the sealing film to prevent the ink from flowing out.

[0050] In other embodiments, other structures or components may be used to close the ink outlet 21, which are not limited herein.

[0051] In other embodiments, a sealing member may also be provided at the bottle mouth of the container main body portion 10, so as to close the ink outlet 21.

[0052] In the embodiments provided by the present application, the container main body portion 10 and the ink outlet forming portion 20 are detachably connected to facilitate the replacement of the container main body portion 10. A fixed connection method by welding or an integral molding method may also be used for connection.

[0053] In a feasible embodiment, refer to Figure 2 、 Figure 4 、 Figure 8 And Figure 10 As shown, an external thread portion 11 is provided on the outer peripheral wall of the container main body portion 10, and an internal thread portion 24 is provided on the inner peripheral wall of the ink outlet forming portion 20. A thread fit may be formed between the external thread portion 11 and the internal thread portion 24, so as to realize the detachable connection between the container main body portion 10 and the ink outlet forming portion 20. When replacing the container main body portion 10, only by rotating the container main body portion 10 or the ink outlet forming portion 20, the container main body portion 10 can be separated from the ink outlet forming portion 20, and then the filled container main body portion 10 can be rotationally connected to the ink outlet forming portion 20.

[0054] In other embodiments, the container main body portion 10 and the ink outlet forming portion 20 may also be connected by detachable connection methods such as snap connection, lock connection or pin connection, etc. However, the thread connection is the optimal detachable connection method, which is not limited herein.

[0055] In order to achieve self-filling of the ink, in the embodiments provided by the present application, with reference to Figure 4 , Figure 9 and Figure 10 as shown, a third ink flow channel 22 is further provided in the ink outlet forming portion 20. A plurality of communication holes 23 are provided at one end of the third ink flow channel 22 close to the ink outlet 21. After the ink flowing out of the self-flowing tube body 30 passes through the third ink flow channel 22, under the action of its own gravity, it can automatically flow out through the communication holes 23. The number of the communication holes 23 can be set according to the speed required for ink filling to meet the requirement of ink flow rate, and no limitation is made here.

[0056] In the embodiments provided by the present application, a valve member can also be provided at one end of the third ink flow channel 22 close to the ink outlet 21. The valve member can control the ink in the third ink flow channel 22 to flow out from the ink outlet 21. When there is ink flowing, under the action of the gravity of the ink itself, the ink can open the outlet of the valve member so that the ink can flow out. When there is no ink flowing, the valve member remains in a closed state.

[0057] In other embodiments, the opening of the valve member can also be assisted by other components, as long as normal filling is ensured, and no limitation is made here.

[0058] In other embodiments, other structures or components capable of realizing self-filling of the ink are provided at one end of the third ink flow channel 22 close to the ink outlet 21, and no limitation is made here.

[0059] The structure, features and effects of the present utility model have been described in detail based on the embodiments shown in the drawings. The above are only the preferred embodiments of the present utility model, but the present utility model is not limited to the scope shown in the drawings.
