Among them, the water guide core is connected with the pen head by plug-in connection, and the acrylic pigment in the ink storage bag is guided to the tip of the pen head for writing output by capillary action.
[0003] However, in practical application, it is found that in the current water guide core and pen head cooperation scheme, although it will not affect the flow of substances below 1 μm, due to the mineral powder (such as titanium dioxide, calcium carbonate, etc. for adjusting the hiding power) with a particle size of 3-5 μm in the acrylic pigment formula, such micro-particle substances will cause serious technical defects in the traditional plug-in structure. The specific performance is: the deformation of the water guide core will affect the capillary action, and the pigment particles will gradually accumulate in the plug-in transition zone of the pen head and the water guide core. This accumulation not only forms a physical blockage barrier, but also changes the conduction of capillary action, eventually leading to a decrease in ink supply efficiency and uneven pen touch, and even the problem of being unable to write.

DETAILED DESCRIPTION
[0026] The utility model will be further detailed in the following with the embodiment given by the accompanying drawings.
[0027] Refer to Figures 1-7 Shown,
[0028] An integral water guide core 4 propylene pen, including pen holder 1, set in pen holder 1 for storing propylene pigment's ink storage bag 2, install in pen holder 1's regulator 3, water guide core 4 is worn in regulator 3, for with water guide core 4 pigment is written pen head assembly 5, the axial setting of regulator 3 is used for wearing water guide core 4's through -hole 31, water guide core 4 is worn in this through -hole 31, pen head assembly 5 includes shell 51 and pen head 52, pen head 52 and water guide core 4 are made of fiber and are integrally arranged, shell 51 and pen head 52 interference fit, and shell 51 is installed with pen holder 1, to limit pen head 52 swing in the writing process.
[0029] The fiber of the water guide core 4 and the pen head 52 are integrally arranged, which can be integrally formed. The pores between the fibers are preferably ≥5μm to allow the mineral particles in the propylene pigment to pass through, avoiding blockage. The shell 51 and the pen head 52 are in interference fit to fix the position of the pen head 52, reducing the influence of capillary action caused by the swing of the pen head 52 during writing. The capillary action of the fiber material is directly conducted to the pen head 52 through the integrated structure, and the pigment is stably delivered to the pen tip from the ink storage bag 2 through the water guide core 4, ensuring continuous and uniform ink supply. Moreover, during assembly, only the pigment needs to be filled into the ink storage bag 2, then the regulator 3 is installed into the pen barrel 1, the water guide core 4 is inserted into the through hole 31 of the regulator 3, and the shell 51 of the pen head assembly 5 is assembled in place to expose the pen head 52.
[0030] In the preferred scheme, the pen head 52 side is provided with a plurality of positioning grooves 521, and the shell 51 is provided with positioning members 511 at the corresponding positions; when the shell 51 is installed to the pen barrel 1, the positioning members 511 are clamped into the positioning grooves 521. The cooperation of the positioning grooves 521 and the positioning members 511 limits the axial displacement of the water guide core 4, preventing it from being pulled out of the regulator 3. During installation, the water guide core 4 is first inserted into the through hole 31 of the regulator 3, and then the shell 51 is installed in place, at which time the positioning members 511 on the shell 51 will be clamped into the positioning grooves 521, further improving the connection strength of the shell 51 and the pen head 52, while preventing the pen head 52 from being pulled out of the shell 51. A mechanical locking can be formed. This design ensures the stability of the pen head 52 while simplifying the assembly steps. In addition, the shell 51 and the pen barrel 1 can be installed in a threaded connection or interference fit manner, preferably in an interference fit manner, which can avoid damage to the water guide core 4.
[0031] In order to make the installation of the water guide core 4 more convenient and the action efficiency of the water guide core 4 higher, the side edge of the water guide core 4 is provided with a step 41, and the inner wall of the through hole 31 of the regulator 3 is provided with a plurality of protrusions 32 for positioning the step 41, the adjacent protrusions 32 have flow channels 33 for the pigment to enter, and when the step 41 is limited by the abutment of the protrusions 32, the flow channels 33 are in communication with the surface of the step 41 to guide the water through the step 41 and the pigment.
[0032] The step 41 and the protrusion 32 abut to achieve axial limiting, realize quick installation, and the flow channel 33 provides a channel for the pigment to enter the wick 4. The pigment contacts the surface of the step 41 through the flow channel 33 and is transported by the capillary action of the fiber. The stepped structure of the step 41 increases the pigment contact area and improves the wicking efficiency, and the distribution of the multiple flow channels 33 ensures that the pigment enters the wick 4 uniformly. The protrusion 32 not only plays a role in abutting and limiting the step 41, but also controls the ink supply amount to avoid the problem of ink leakage of the pen tip 52 caused by excessive ink supply. The abutting and limiting role of the protrusion 32 can control the ink supply amount, limit the installation of the wick 4, realize quick installation in place, and cooperate the flow channel 33 with the surface of the step 41 of the wick 4 to improve the ink supply amount. At this time, the scheme can not only improve the ink supply amount, but also appropriately control the ink supply amount to avoid the problem of ink leakage of the pen tip 52.
[0033] Further setting, the position corresponding to the hole 31 of one end of the regulator 3 corresponding to the ink storage bag 2 is also provided with a plurality of positioning blocks 34, the wick 4 corresponding to one end of the ink storage bag 2 passes through the hole 31, and the side surface of the passing part cooperates with the positioning block 34 to limit the swing of the wick 4. The positioning block 34 contacts the side surface of the wick 4 to limit its radial swing. The wick 4 passes through the end and extends into the ink storage bag 2, which enhances the stability of the wick 4 and improves the straightness of the pigment conveying path to a certain extent, thereby reducing the flow resistance.
[0034] Specifically, the positioning blocks 34 between the adjacent positioning blocks 34 form an opening for the pigment to pass through, and the opening is in communication with the flow channel 33. The opening between the positioning blocks 34 serves as a communication channel between the ink storage bag 2 and the flow channel 33, and the pigment enters the flow channel 33 from the ink storage bag 2 through the opening, and then enters the wick 4 through the surface of the step 41.
[0035] In order to increase the strength of the positioning block 34 and avoid its fracture, in an optional scheme, the adjacent positioning blocks 34 are also connected by a reinforcing rib 35.
[0036] The reinforcing rib 35 improves the structural strength of the positioning block 34 and prevents the positioning block 34 from being broken during installation. At the same time, the reinforcing rib 35 serves as a support framework to maintain the position of each positioning block 34, which can ensure the limiting relationship with the wick 4.
[0037] The side of the reinforcing rib 35 corresponding to the wick 4 is arc-shaped transition, and cooperates with the side of the positioning block 34 corresponding to the wick 4 to form a circular arc surface. The arc-shaped transition design can better cooperate with the peripheral surface of the wick 4, and the limiting swing effect on the wick 4 is more stable.
[0038] As an embodiment that enables stable cooperation between the positioning block 34 and the wick 4, the position of the positioning block 34 corresponds to the position of the protrusion 32, and corresponds to one side of the hole center of the hole 31 and is closer to the hole center of the hole 31 than the protrusion 32.Figure 5 、 6 , As shown in FIG. 7, the positioning block 34 is more capable of contacting the water conduit 4 than the protrusion 32, at this time the positioning block 34 can provide a more stable matching relationship.
[0039] In addition, as an embodiment capable of making the pigment flow more uniform, the water conduit 4 is in contact with the positioning block 34, and there is a gap 6 between the water conduit 4 and the protrusion 32. By using the gap 6 between the protrusion 32 and the water conduit 4, the plurality of flow channels 33 can be connected to each other, and the pigment can be in more uniform contact with the step 41 of the water conduit 4, and the ink can flow more smoothly.
[0040] Preferably, the water conduit 4 and the pen head 52 are both nylon fibers. In addition, those skilled in the art should know in common sense that the porosity of the water conduit 4 and the pen head 52 needs to be able to pass the particles of the acrylic pigment.
[0041] The high strength and corrosion resistance of the nylon fiber are suitable for long-term contact with the acrylic pigment, the regular porosity (≥5 μm) allows the mineral particles (3-5 μm) to pass freely, while maintaining the capillary effect efficiency. This design takes into account the durability and functionality of the material, prolonging the service life of the pen. Compared with the plastic stretching scheme in the prior art, the present scheme has low cost and low processing difficulty.
[0042] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the scope of the present application is within the protection scope of the present application. It should be noted that for ordinary skilled persons in the art, some improvements and decorations without departing from the principles of the present application can also be considered as the protection scope of the present application.
