Abstract
Description
Technical Field
[0001] This utility model relates to the field of marker technology, and in particular to a cotton-wick marker. Background Technology
[0002] Marker pens, also known as markers or drawing pens, are writing and drawing tools, mainly used for marking and drawing. More specifically, marker pens can be categorized based on their ink dispensing method into wick markers, direct-ink markers, and valve markers.
[0003] Patent CN221937907U discloses a multi-purpose marker pen and marking device, belonging to the category of cotton-wick marker pens. This marker pen includes a casing and a refill. The refill is located inside the casing and connected to one end. As shown in the accompanying drawings, the refill is secured by multiple ribs on the inner wall of the casing. When using a cotton-wick marker, if the refill dries out, becomes damaged, or is stained with other colors, it usually needs to be replaced to ensure continued use. Because the aforementioned marker does not include a structure to assist in refill removal, users easily get their hands dirty when removing old refills. Furthermore, when inserting a new refill, the lack of travel limit settings on the ribs results in random insertion depth. If inserted too deeply, the refill becomes stuck, making it difficult to remove next time, and the short extension length leads to a poor drawing experience. Conversely, if inserted too shallowly, the new refill easily falls out, and the long extension length makes it difficult to control the refill and maintain a stable state during drawing.
[0004] Therefore, improvements are still needed to the existing cotton-core markers to solve the problems of getting hands dirty when removing and installing the refills and the inconsistent installation results. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0041] Marker pens, also known as markers or drawing pens, are writing and drawing tools, primarily used for marking and drawing. More specifically, marker pens can be categorized based on their ink dispensing method: wick markers, direct-ink markers, and valve markers. Among these:
[0042] Existing cotton-core markers lack a mechanism to assist in refilling and removing the refill, making it easy for users to get their hands dirty when removing old refills. Furthermore, when inserting a new refill, the lack of a travel limit setting on the reinforcing ribs results in random insertion depth. If inserted too deeply, the refill becomes stuck, making it difficult to remove next time, and the shorter extension length leads to a poor drawing experience. Conversely, if inserted too shallowly, the new refill is prone to falling out, and the longer extension length makes it difficult to control the refill and keep it stable while drawing.
[0043] Example 1
[0044] like Figures 1 to 6 As shown, this embodiment of the utility model provides a cotton wick marker 1, wherein:
[0045] like Figure 1 As shown, the cotton-core marker 1 includes a pen barrel 10, and a first pen tip (not shown in the figure), a first pen refill, and a first pen cap 30, all located at one end of the pen barrel 10; the first pen cap 30 includes a first pen shell 300 that covers the first pen tip and a first pen cap 301 that is detachably connected to the first pen shell 300.
[0046] like Figures 2 to 3 As shown, based on the shape of the pen refill, they can be roughly divided into two types: flat refills (such as...) Figure 2 As shown), conical core (such as Figure 3 (as shown);
[0047] like Figures 4 to 5 As shown, the first pen cap 301 is inserted into one end of the first pen shell 300 and is fixedly provided with an upper clamping claw 302 and a lower clamping claw 303; the upper clamping claw 302 and the lower clamping claw 303 are used to cooperate in clamping the first pen refill under the force applied by the user; the first pen cap 30 also includes a first indicator piece 304; the first indicator piece 304 is located on the upper clamping claw 302 or the lower clamping claw 303; the first indicator piece 304 is used to indicate the extension length of the first pen refill during installation.
[0048] The cotton-core marker 1 provided in this embodiment makes full use of the internal space of the first pen cap 30 and adds a structure that can assist in the installation and removal of the first pen core. Specifically:
[0049] When it is necessary to remove the old first pen refill, the first pen cap 301 is taken out. By applying force to the upper jaw 302 and the lower jaw 303, the upper jaw 302 and the lower jaw 303 cooperate to clamp the old first pen refill, so that the old first pen refill can be pulled out from the first pen tip. Since the user does not need to directly touch the old first pen refill, the hands can be kept clean.
[0050] When a new first pen refill needs to be inserted, place the new first pen refill horizontally between the upper jaw 302 and the lower jaw 303. Adjust it so that the end of the new first pen refill is aligned with the lower end of the first indicator plate 304. After alignment, clamp the new first pen refill and insert it into the first pen tip until the upper jaw 302 and the lower jaw 303 reach the first pen tip. This completes the installation of the new first pen refill. The first indicator plate 304 effectively controls the insertion depth of the first pen refill, ensuring proper insertion and providing the user with a better drawing or writing experience.
[0051] like Figure 1 , Figure 2 and Figure 5 As shown, the cotton-core marker 1 is a single-headed pen; the first lead is a flat lead, meaning the marker is single-headed with only one cap, which is used to assist in assembling and disassembling the flat lead; the clamping ends of the upper jaw 302 and the lower jaw 303 are both pointed, which can ensure the stability of the clamping.
[0052] like Figure 6 As shown, the first pen shell 300 and the first pen cap 301 are interference-fitted by multiple annular ribs 305, making them easy to assemble and disassemble and cost-effective.
[0053] like Figures 4 to 5 As shown, the upper jaw 302, lower jaw 303, first indicator piece 304, and first pen cap 301 are integrally formed, saving assembly steps.
[0054] Example 2
[0055] This utility model embodiment provides a cotton-core marker 1, which is a single-headed marker with only one cap and is used to assist in the disassembly and assembly of the conical core. The similarities with Embodiment 1 will not be repeated here. The difference is that the cotton-core marker 1 is a single-headed marker; the first core is a conical core.
[0056] The gripping ends of the upper jaw 302 and the lower jaw 303 are both pointed, which can ensure the stability of the gripping.
[0057] Or such as Figure 7 As shown, the clamping ends of the upper jaw 302 and the lower jaw 303 are both concave arc-shaped ends. Since the clamping ends have a contour that better matches the first pen refill, the clamping stability can be further improved.
[0058] Example 3
[0059] This utility model embodiment provides a cotton-core marker 1, which is double-ended. The first pen cap 30 and the second pen cap 40 are used to assist in the disassembly and assembly of the flat core and the conical core, respectively.

Figures 9 to 10 As shown, the second pen cap 40 includes a second pen shell 400 that covers the second pen tip, and a second pen cap 401 detachably connected to the second pen shell 400. One end of the second pen cap 401 is inserted into the second pen shell 400 and is also fixedly provided with an upper clamping claw 302 and a lower clamping claw 303. The upper clamping claw 302 and lower clamping claw 303 on the second pen cap 401 are used to clamp the second pen refill under the force applied by the user. The second pen cap 40 also includes a second indicator plate 402. The second indicator plate 402 is located on the upper clamping claw 302 or the lower clamping claw 303. The second indicator plate 402 is used to indicate the extension length of the second pen refill during installation. The specific usage process is as follows:
[0061] When the first pen refill needs to be removed, take out the first pen cap 301, clamp it with the upper jaw 302 and the lower jaw 303 and pull out the old first pen refill; when a new first pen refill needs to be inserted, place the new first pen refill horizontally between the upper jaw 302 and the lower jaw 303, align the end of the new first pen refill with the first indicator piece 304, and then insert it.
[0062] When the second pen refill needs to be removed, take out the second pen cap 401, clamp it with the upper jaw 302 and the lower jaw 303 and pull out the old second pen refill; when the new second pen refill needs to be inserted, place the new second pen refill horizontally between the upper jaw 302 and the lower jaw 303, align the end of the new second pen refill with the second indicator piece 402, and then insert it.
[0063] By setting up a first pen cap 30 and a second pen cap 40 for assisting in the disassembly and assembly of flat and conical pen refills respectively, users can easily remove the corresponding pen caps to disassemble and assemble the pen refills.
[0064] Example 4
[0065] This utility model embodiment provides a cotton-core marker 1, which is double-ended. Of the two caps, only one can be used to assist in the disassembly and assembly of flat and conical refills, while the other cap is a regular cap and does not have the function of assisting in disassembly and assembly.
