Description

Technical Field

[0001] This utility model generally relates to the technical field of stationery, and more specifically, to a portable ink-filling inkstone. Background Technology

[0002] As one of the Four Treasures of the Study, the inkstone is used to hold the ink needed for writing with a brush. With social progress and technological development, the traditional inkstone for grinding ink has gradually been abandoned due to its inconvenience. Currently, calligraphy practitioners usually use commercially available bottled ink directly for brush writing. However, dipping the brush directly from the bottle can easily lead to using too much ink, which is not conducive to writing. Therefore, most practitioners pour the ink into the inkstone. During calligraphy practice, this requires frequent pouring, which can easily spill onto other surfaces. The amount of ink poured is difficult to control, the ink dries quickly, and it is inconvenient to carry.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] The present invention includes a series of simplified concepts, which will be further explained in detail in the detailed description section. This present invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] The purpose of this utility model is to overcome at least one of the defects of the prior art and provide a portable ink-filling inkstone.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A portable ink-filling inkstone includes:

[0008] An inkstone, with an inkwell for storing liquid ink; and

[0009] An ink tray is vertically mounted inside the ink reservoir. An ink-dipping chamber is formed inside the ink tray. An ink-filling hole is provided on the bottom wall of the ink-dipping chamber. The opening and closing of the ink-filling hole is controlled by a one-way valve.

[0010] Specifically, when the ink disk descends to a first position where it contacts the liquid in the ink pool, the one-way valve is opened to allow the liquid to enter the ink-dipping chamber; when the ink disk rises to a second position where it is separated from the liquid, the one-way valve is closed.

[0011] In one embodiment of this utility model, the inkstone and the ink tray are vertically connected by a movable component. The movable component includes a positioning post fixed in the ink pool and a movable rod connected to the ink tray. The movable rod is sleeved with the positioning post and can move up and down along the positioning post.

[0012] In one embodiment of this utility model, the positioning post is hollow and has a sliding groove on its side wall. The movable rod is sleeved inside the positioning post and is provided with a first hook that slides with the sliding groove.

[0013] In one embodiment of this utility model, the contact surface between the movable rod and the positioning post is provided with a damping element to achieve relative fixation of the movable rod.

[0014] In one embodiment of this utility model, the ink disk and the movable rod are detachably connected.

[0015] In one embodiment of this utility model, the bottom wall of the ink disk protrudes upward to form a boss, and the movable rod passes through the boss and engages with the boss.

[0016] In one embodiment of the present invention, the movable rod is provided with a second hook and a limiting plate at one end near the boss, and the top of the boss is limited between the second hook and the limiting plate.

[0017] In one embodiment of the present invention, the top of the movable rod is provided with an operating part, which is disposed above the boss.

[0018] In one embodiment of this utility model, the one-way valve is configured as a soft rubber sealing plate. One end of the soft rubber sealing plate is provided with a barb portion that engages with the ink disk, and the other end is provided with a plug portion that is inserted into the injection hole.

[0019] In one embodiment of the present invention, a sealing cover for sealing the top of the inkwell is further included, the sealing cover being rotatably connected to the inkstone.

[0020] As can be seen from the above technical solution, the advantages and positive effects of the portable ink-filling inkstone provided by this utility model are as follows:

[0021] This portable inkstone includes an inkstone and an ink tray. Ink is contained in the ink pool of the inkstone, and the ink tray is height-adjustable within the ink pool. When the ink tray descends to contact the ink in the ink pool, the one-way valve above the injection hole opens under the pressure difference, allowing ink to enter the dipping chamber. Once there is sufficient ink in the dipping chamber, the ink tray is pulled upwards, separating it from the ink in the ink pool, and the one-way valve closes under gravity. Calligraphy practitioners can then directly dip their brushes into the ink in the dipping chamber for use. This design allows for convenient ink refilling, easy control of the amount of ink added, prevents ink spillage, and is convenient to use and carry. Attached Figure Description

[0035] Please see Figures 1-3 This utility model provides a portable inkstone, including an inkstone 10 and an ink tray 20. The inkstone 10 has an ink pool 101 for storing liquid (ink), and the ink tray 20 is vertically oriented within the ink pool 101. An ink-dipping chamber 201 is formed within the ink tray 20, and an injection hole 202 is provided on the bottom wall of the ink-dipping chamber 201. The opening and closing of the injection hole 202 is controlled by a one-way valve 30. When the ink tray 20 descends to a first position in contact with the ink, the one-way valve 30 is opened, allowing ink to enter the ink-dipping chamber 201 through the injection hole 202. When the ink tray 20 rises to a second position separated from the ink, the one-way valve 30 is closed, allowing the user to dip their brush into the ink in the ink-dipping chamber 201 for calligraphy practice.

[0036] Specifically, in this embodiment, the inkstone 10 can be, for example, a round box shape, a square box shape, etc. A sealing cap 40 is provided on the top of the inkstone 10, which is used to seal the top of the inkwell 101. A sealing ring 41 is provided on the inner wall of the sealing cap 40 to ensure a sealing effect on the inkstone 10. By providing the sealing cap 40, the inkstone 10 is easy to carry and the ink inside the inkstone 10 is prevented from leaking out.

[0037] Furthermore, in one embodiment, the sealing cap 40 is rotatably connected to the inkstone 10. Specifically, the outer wall of the inkstone 10 is provided with a pair of connecting ears 12, and a rotating shaft 13 is fixed on the connecting ears 12. The end of the sealing cap 30 is rotatably connected to the rotating shaft 13. This arrangement facilitates the opening and closing of the sealing cap 40.

[0038] Further, in this embodiment, please refer to Figures 4-6 The inkstone 10 and the ink tray 20 are connected in a height-adjustable manner via a movable component. Specifically, the movable component includes a positioning post 11 fixed within the ink pool 201 and a movable rod 21 connected to the ink tray 20. The movable rod 21 is sleeved with the positioning post 11 and can move up and down along the positioning post 11.

[0039] Specifically, the positioning post 11 is fixed in the middle of the inkstone 10. The positioning post 11 is a hollow cylinder with a sliding groove 111 on its side wall. The movable rod 21 is inserted into the inner cavity of the positioning post 11. The movable rod 21 is provided with a first hook 211 that slides with the sliding groove 111. The first hook 211 is constructed as an elastic hook, which can retract inward when the movable rod 21 is inserted into the positioning post 11, and pop outward when it reaches the position of the sliding groove 111, thereby achieving engagement with the positioning post 11. More preferably, the positioning post 11 is provided with at least two sliding grooves 111, and the movable rod 21 is also provided with at least two first hooks 211 to better ensure the stability of the movable rod 21 during lifting and lowering.

[0040] Furthermore, in one embodiment, a damping element 212 is provided on the contact surface between the movable rod 21 and the positioning post 11 to achieve relative fixation of the movable rod 21. Specifically, the damping element 212 is constructed as a rubber ring sleeved on the movable rod 21 near its lower position. By providing resistance between the positioning post 11 and the movable rod 21 through the damping element 212, the ink disk 20 can be fixed at any height.

[0041] Furthermore, in one embodiment, the ink disk 20 and the movable rod 21 are detachably connected, making assembly and cleaning more convenient. Specifically, a boss 22 protrudes upward from the center of the bottom wall of the ink disk 20, and the movable rod 21 passes through the boss 22 and engages with it. This design effectively saves space and improves the portability of the product.

[0042] Furthermore, the structure for the engagement between the movable rod 21 and the boss 22 is as follows: the end of the movable rod 21 near the boss 22 is provided with a second hook 213 and a limiting plate 214. The top of the boss 22 has an opening 203 through which the movable rod 21 passes. The limiting plate 214 is positioned above the opening 203, and the second hook 213 is positioned below the opening 203. The diameter of the limiting plate 214 is larger than the diameter of the opening 203, so that the top of the boss 22 is limited between the second hook 213 and the limiting plate 214.

[0043] It should be noted that in other embodiments of this utility model, the ink disk 20 and the movable rod 21 may also be an integral structure or be fixedly connected by means of adhesive bonding, etc. This disclosure does not impose specific limitations.

[0044] Furthermore, in one embodiment, the top of the movable rod 21 is also provided with an operating part 215, which is disposed above the boss 22.

[0045] Furthermore, in one embodiment, the one-way valve 30 is configured as a soft rubber sealing plate. One end of the soft rubber sealing plate has a barb portion 31 that engages with the ink tray 20, and the other end has a plug portion 32. The barb portion 31 engages with the bottom of the ink tray 20 to prevent the soft rubber sealing plate from coming out of the ink tray 20. The plug portion 32 is positioned opposite the ink injection hole 202. The plug portion 32 can be, for example, a frustum-shaped structure. When the ink tray 20 is in the second position, the plug portion 32 is inserted into the ink injection hole 202. By providing the plug portion 32, the ink injection hole 202 can be tightly sealed to prevent ink leakage.

[0046] The working principle of the portable ink-filling inkstone provided in this embodiment is as follows:

[0047] See Figure 7 When you begin writing, open the sealing cover 40 (before opening the cover, the ink tray 20 is pushed to the bottom of the ink pool 101 of the inkstone 10, and ink enters the ink tray 20), and grasp the operating part 215 of the movable lever 21 to pull it upwards, causing the ink tray 20 immersed in the inkstone 10 to rise from the bottom of the inkstone 10. See also Figure 8 At this point, the ink in the ink tray 20, under the influence of gravity, causes the one-way valve 30 to seal the ink injection hole 202, preventing the ink in the ink tray 20 from flowing out through the ink injection hole 202. Continue raising the ink tray to a suitable position for easier writing.

[0048] When there is not enough ink in the ink tray 20, press down on the operating part 215 of the movable lever 21 to immerse the ink tray 20 into the ink pool 101 of the inkstone 10. Under the pressure difference between the inside and outside of the ink dipping chamber 201 and the ink pool 101, the one-way valve 20 is opened, and the ink in the ink pool 101 enters the ink dipping chamber 201 through the injection hole 202. After the ink in the ink dipping chamber 201 reaches the required amount, lift the ink tray 20 upward to continue writing.

[0049] When finishing writing, press down on the movable lever 21 to immerse the ink tray 20 into the ink pool 101 of the inkstone 10, and then close the sealing cover 40. The sealing cover 40 seals the top of the inkstone, preventing ink from spilling or drying out, and making it convenient to carry.
