[0023] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0024] Reference Figure 1-7 As shown,

[0025] A water diversion structure applicable to writing tools with different functional nibs comprises an ink regulator 1 and a water diversion core 2 arranged in the ink regulator 1, wherein the water diversion core 2 is used to divert ink from an ink bag 3; a through hole 11 is arranged at the axis of the ink regulator 1, and the water diversion core 2 is located in the through hole 11; a plurality of protrusions 12 are arranged along the circumferential direction on the inner wall of one end of the through hole 11 on the ink regulator 1 corresponding to the ink bag 3; the protrusions 12 extend along the axial direction of the through hole 11 and are used to abut against the side surface of the water diversion core 2 to form a positioning; grooves 13 are formed between adjacent protrusions 12, and the water diversion core 2 increases the contact area with the ink through the grooves 13.

[0026] The through hole 11 in this solution has a protrusion 12, and the water guide core 2 is abutted and positioned by the protrusion 12, that is, the diameter of the position of the through hole 11 corresponding to the end of the water guide core 2 is larger than the water guide core 2, and only then can the protrusion 12 be set to abut the water guide core 2, and at this time it means that a groove 13 will be formed between adjacent protrusions 12, and this groove 13 can allow ink to enter, thereby increasing the contact area between the ink and the water guide core 2. At this time, when the writing tool discharges water, it not only has a capillary effect, but also can form a siphon effect, thereby improving the water discharge effect, especially the writing tool with a flexible head. In specific applications, the pen head can be an axe type, a brush type, a beautiful head, a nylon soft head, etc. Since the specific structure is a simple replacement and does not involve the improvement of the pen head structure, it will not be described in detail here.

[0027] In a further configuration, a step 21 is provided on the side of the water diversion core 2, and a plurality of protrusions 12 corresponding to one end of the step 21 cooperate with each other to form an abutment surface 14; when the water diversion core 2 is installed in place in the through hole 11, the step 21 abuts against the abutment surface 14 to form a limit.

[0028] Since there is a protrusion 12 in the through hole 11, and the protrusion 12 has two ends, the protrusion 12 extends along the axial direction of the through hole 11, so one end corresponds to the ink sac 3, and the other end corresponds to the brush head. Since there are multiple protrusions 12, the multiple protrusions 12 corresponding to one end of the brush head will form a surface, which can be called abutment table 14. After the water guide core 2 is installed into the through hole 11 and installed in place, the step 21 can be aligned with the abutment table 14 to form a limit, making the installation more convenient and preventing the water guide core 2 from being installed too far and affecting the water output effect.

[0029] In addition, it can also be arranged as follows: the end of the groove 13 corresponding to the abutment against the table surface 14 is open to allow the ink to contact the step 21 of the water guide core 2.

[0030] The groove 13 not only allows the side of the water-guiding core 2 to have a larger contact area with the ink, but also allows the step 21 to contact the ink. Referring to the step 21 shown in the figure, it extends along the axial direction of the water-guiding core 2, which can assist in water diversion and has a better water diversion effect.

[0031] For the convenience of installation, as an optional embodiment, the end of the water guide core 2 corresponding to the ink bag 3 is set to be conical.

[0032] The conical end of the water-guiding core 2 can make it easier to fit with the multiple protrusions 12 for low-level installation, making it easier to install the water-guiding core 2 when it is inserted from the through hole 11 at the end corresponding to the brush head, thereby reducing the possibility that the end of the water-guiding core 2 is unable to penetrate into the space surrounded by the multiple protrusions 12 and cannot be installed in place due to the abutment of the end of the protrusion 12.

[0033] In order to further facilitate installation, the following technical solution can also be implemented: a guide bevel 15 is provided in the through hole 11 of the ink regulator 1, the diameter of the through hole 11 becomes smaller after passing through the guide bevel 15, and the smaller diameter part of the through hole 11 is close to the protrusion 12.

[0034] The guide slope 15 with a smaller diameter can guide the water guide core 2 with a conical end for installation, making it easier to align the water guide core 2 with a middle position surrounded by a plurality of protrusions 12, making installation more convenient and more efficient.

[0035] In particular, the following technical solution can be further adopted to further improve the convenience of installation. The smaller diameter portion of the through hole 11 after passing through the guiding slope 15 is adapted to the outer diameter of the step 21. The smaller diameter portion of the through hole 11 is adapted to the outer diameter of the step 21, so that after the guiding slope 15 is guided, the step 21 of the water guide core 2 is assembled with the smaller diameter portion of the through hole 11. This assembly will form an interference fit due to the adaptation effect, or a positioning effect due to the size being just right. This interference fit and positioning effect can correct the end position of the water guide core 2, thereby making it easier for the end of the water guide core 2 to be installed, abutted and positioned with the protrusion 12. The guiding slope 15 is a surface that forms a cone (truncated cone) in the through hole 11.

[0036] Preferably, the plurality of protrusions 12 are evenly distributed along the circumference of the through hole 11 .

[0037] The uniform distribution of the protrusions 12 can make the ink contact the side and step 21 of the water-inducing core 2 more uniformly, so that the utilization rate of the diffusion effect is higher. If the protrusions 12 are unevenly distributed, the size of the grooves 13 will be uneven. At this time, the ink in the larger space of the grooves 13 will have poor diffusion effect on both sides after contacting the water-inducing core 2, and the penetration effect on the water-inducing core 2 will be poor. In the case of the same contact area, dividing it into two grooves 13 can expand the penetration effect and thus increase the water-inducing effect. Uniform distribution is a way to maximize the penetration effect, so it can make the water-inducing effect better.

[0038] In addition, in order to facilitate production and installation, the water guide core 2 is a vertically symmetrical structure. This structure does not need to distinguish between the front and back during installation, and can be directly installed, which has a higher installation efficiency.

[0039] The above describes a water diversion structure. The following further describes a water-based pen, including a housing, an ink bag 3 arranged in the housing, a water diversion structure arranged in the housing, and a pen head mounted on the housing for cooperating with the water diversion structure to discharge ink. The pen head is one of a watercolor pen head, a nylon soft pen head, an axe pen head, and a brush pen head (refer to Figure 2 , 5 , 6, 7), where the installation method of the pen head can refer to Figure 1 , 2 , 3, and the water diversion structure adopts the water diversion structure of the brush head writing tool as described above, especially a straight liquid water-based pen.

[0040] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
