Description

Technical Field

[0001] The utility model relates to the technical field of stationery supplies, in particular to a marker pen capable of replenishing ink. Background Art

[0002] In the current stationery market, marker pens are a widely used drawing and marking tool, beloved by designers, students, and office workers for their vibrant colors and smooth writing. However, with continued use, the depletion of the ink inside markers becomes an inevitable problem. Traditional markers generally face a common challenge when their ink runs out: difficulty refilling.

[0003] Specifically, most markers on the market adopt a disposable or closed design. Once the user has used up the ink in the pen, it is difficult to refill it by themselves. Although this design simplifies the manufacturing process and ensures the convenience of initial use, it also brings significant resource waste and environmental pollution problems. Since the refilling process is complicated and difficult to operate, most users tend to choose to directly discard the old pens and buy new markers instead. This not only increases the economic burden on users, but also increases the pressure of plastic waste on the environment. Therefore, we propose a refillable marker to solve the above problems. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the shortcomings of the prior art, the present invention provides a marker pen with refillable ink, which solves the problems raised in the above background technology.

[0006] (2) Technical solution

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] A marker pen with refillable ink comprises a pen barrel, a cotton refill is provided in the pen barrel, the bottom of the cotton refill is connected to and fixed with a pen head, an ink filling tube is sealingly and slidably connected to the cotton refill, a one-way valve is fixedly connected to the inner wall of the ink filling tube, an injection hole is opened on the top inner wall of the ink filling tube, the right end of the ink filling tube extends outside the pen barrel and is fixedly connected to a pull block, a first annular magnet is fixedly connected to the right side of the cotton refill, a second annular magnet is fixedly connected to the ink filling tube, the first annular magnet and the second annular magnet are magnetically connected, and a pen cap is clamped on the pen barrel.

[0009] Furthermore, a guide hole is provided on an inner wall of one side of the pen shaft, and the pen shaft is slidably connected to the ink filling tube through the guide hole.

[0010] Furthermore, a positioning hole is provided on an inner wall of one side of the cotton pen core, and the cotton pen core is slidably connected to the ink filling tube through the positioning hole.

[0011] (3) Beneficial effects

[0012] Compared with the prior art, the present invention provides a marker pen that can be refilled with ink, which has the following features:

[0013] Beneficial effects:

[0014] The utility model drives the ink filling tube to move by pulling the pull block, and the ink filling tube drives the second annular magnet to separate from the first annular magnet, and the ink filling tube is limited by the second annular magnet. When one side of the second annular magnet contacts the inner wall of one side of the pen barrel, the injection hole on the ink filling tube leaks out, and then ink is added to the ink filling tube through the injection hole, and then enters the cotton pen core through the ink filling tube. After the ink filling is completed, the pull block is pushed so that the second annular magnet on the pull block is magnetically connected to the first annular magnet, and the ink filling tube is fixed. The one-way valve is set to prevent the ink from flowing back, so that the marker pen can be easily filled with ink. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example

[0023] like Figure 1-5 As shown, an embodiment of the present invention provides an ink-refillable marker pen, comprising a pen barrel 1, a cotton refill 2 provided in the pen barrel 1, a pen tip 3 connected to and fixed at the bottom of the cotton refill 2, an ink filling tube 4 sealingly and slidingly connected to the cotton refill 2, a one-way valve 5 fixedly connected to the inner wall of the ink filling tube 4, an injection hole 6 is provided on the top inner wall of the ink filling tube 4, the right end of the ink filling tube 4 extends to the outside of the pen barrel 1 and is fixedly connected to a pull block 7, a first annular magnet 8 is fixedly connected to the right side of the cotton refill 2, a second annular magnet 9 is fixedly connected to the ink filling tube 4, the first annular magnet 8 is magnetically connected to the second annular magnet 9, a pen cap 10 is clamped on the pen barrel 1, and when the After the ink in the pen is used up, pull the pull block 7, and the pull block 7 drives the ink filling tube 4 to move. The ink filling tube 4 drives the second annular magnet 9 to separate from the first annular magnet 8, and the ink filling tube 4 is limited by the second annular magnet 9. When one side of the second annular magnet 9 contacts the inner wall of one side of the pen barrel 1, the injection hole 6 on the ink filling tube 4 leaks out, and then ink is added to the ink filling tube 4 through the injection hole 6, and then enters the cotton pen core 2 through the ink filling tube 4. After the ink filling is completed, push the pull block 7 so that the second annular magnet 9 on the pull block 7 is magnetically connected to the first annular magnet 8, and the ink filling tube 4 is fixed. The one-way valve 5 is set to prevent the ink from flowing back.

[0024] In some embodiments, a guide hole is opened on the inner wall of one side of the pen shaft 1, and the pen shaft 1 is slidingly connected to the ink filling tube 4 through the guide hole. A positioning hole is opened on the inner wall of one side of the cotton pen core 2, and the cotton pen core 2 is slidingly connected to the ink filling tube 4 through the positioning hole. Through the setting of the positioning hole, the ink filling tube 4 can only move left and right.

[0025] The working principle or structural principle is that when in use, when the ink in the marker pen is used up, the pull block 7 is pulled, and the pull block 7 drives the ink filling tube 4 to move, and the ink filling tube 4 drives the second annular magnet 9 to separate from the first annular magnet 8, and the ink filling tube 4 is limited by the second annular magnet 9. When one side of the second annular magnet 9 contacts the inner wall of one side of the pen barrel 1, the injection hole 6 on the ink filling tube 4 leaks out, and then ink is added to the ink filling tube 4 through the injection hole 6, and then enters the cotton pen core 2 through the ink filling tube 4. After the ink filling is completed, the pull block 7 is pushed, so that the second annular magnet 9 on the pull block 7 is magnetically connected to the first annular magnet 8, and the ink filling tube 4 is fixed. The one-way valve 5 is set to prevent the ink from flowing back.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
