[0002] An acrylic paintbrush refers to a paintbrush of various shapes made of nylon or acrylic fiber, especially for use with acrylic or polymer painting pigments. Since these pigments dry very quickly, the paintbrush dipped in the pigment has to be kept in water for standby.
[0003] As a commonly used paintbrush for painting at present, the acrylic pen is widely used among various people. At present, all acrylic pens are equipped with pen caps. However, among the users, especially children and primary school students, often forget to cover the pen cap during use, resulting in the evaporation of the ink, which causes poor ink flow and even renders the acrylic pen useless.
[0004] Therefore, it is necessary to improve the structure of the acrylic pen to avoid the problem that the service life of the acrylic pen and the storage life of the ink differ too much due to the negligence of the user. Content of the Utility Model
[0005] The purpose of the utility model is to provide an acrylic pen with anti-drying ink, so as to protect the ink of the acrylic pen from drying, thereby avoiding the problem that the service life of the acrylic pen is affected due to the ink drying because the pen cap is not properly covered.

[0020] Now, the representative embodiments shown in the drawings will be further refined. It should be understood that the following description is not intended to limit the embodiments to a preferred embodiment. On the contrary, it is intended to cover alternative forms, modifications, and equivalent forms that may be included within the spirit and scope of the described embodiments as defined by the appended claims.
[0021] Based on the problem that the current acrylic pen is prone to ink volatilization affecting the service life of the acrylic pen due to the pen cap not being properly covered, the applicant has developed an acrylic pen with anti-drying ink. This acrylic pen can effectively improve the service life of the acrylic pen. Even if the pen cap is not properly covered, it will not have too much impact on the service life of the acrylic pen.
[0022] Such as Figure 1-2As shown in the figure, the applicant provides an acrylic pen with anti-drying ink. The specific structure is as follows: The acrylic pen includes a pen barrel 1 for filling ink and a pen tip 2 for writing. The pen barrel 1 and the pen tip 2 are detachably connected as a whole. Here, the inventor sets a reduced-diameter part 10 at the rear of the pen tip 2, and anti-slip lines are provided on the reduced-diameter part 10. The front end of the pen barrel 1 is inserted into the reduced-diameter part 10 of the pen tip 2 and is detachably connected to the pen tip 2. In this way, the plastic pen barrel 1 is connected to the tail of the pen tip 2 as a whole. Ink is filled in the pen barrel 1.
[0023] In order to prevent the ink in the pen barrel 1 from drying out, the inventor adjusted the structure of the pen tip 2.
[0024] Regarding the structure of the pen tip 2, specifically, the front part of the pen tip 2 has a nib 3, and the outside of the nib 3 is in a conical structure. The front end of the nib 3 has an ink outlet hole 4 communicating with the inside. A ball 5 is arranged behind the ink outlet hole 4 inside the nib 3. The ball 5 is of a ceramic structure, which reduces costs and is easy to slide. Usually, the ink passes from the pen barrel 1 through the inside of the pen tip 2 to the ball 5 of the nib 3. As the ball 5 rolls, the ink is carried out of the nib 3 and adheres to the writing object.
[0025] In order to prevent the ink from drying out from the outside to the inside along the ink overflow channel, the inventor sets a pen bowl 6 for supporting the ball 5 behind the ball 5 inside the nib 3. The pen bowl 6 is used to support the ball 5. In order not to affect the passage of ink, the pen bowl 6 is hollowed out and the concave side matches the ball 5. In this way, the ball 5 is restricted and movably located in the accommodation space formed between the pen bowl 6 and the ink outlet hole 4. The ball 5 rolls in this space to transfer the ink to the outside of the nib 3.
[0026] There are gaps between the ball 5 and the pen bowl 6 and between the ball 5 and the inner wall of the ink outlet hole 4 of the nib 3. When writing, the ink adheres to the writing object along this gap with the ball 5. However, when writing is completed, this gap will cause the ink to dry out from the outside to the inside in sequence. For this reason, the inventor also sets an adjusting spring 7 inside the pen tip 2. The rear end of the adjusting spring 7 is fixedly restricted inside the pen tip 2, and the front end of the adjusting spring 7 is connected to the rear part of the ball 5. The adjusting spring 7 is responsible for pushing the ball 5 forward when writing is completed, so that the ball 5 is closely attached to the inner wall of the nib 3, reducing or eliminating the gap formed between the ink and the inner wall of the nib 3 during writing. In this way, a sealed environment can be formed in the space inward from the ink outlet hole 4. Especially after the ink remaining at the ball 5 and the ink outlet hole 4 dries, a blurred film can be formed, which can better improve the sealing performance between the ball 5 and the nib 3. Under this sealing effect, the ink behind the ball 5 inside the nib 3 is isolated from the outside world, avoiding further solidification and maintaining the wettability of the ink.
[0027] When writing is required here, the protective film formed by the residual ink is rubbed off as the ball 5 rolls, thereby exposing the ball 5 again. Under the external pressure, the ball 5 is pressed back inward, causing a gap to reappear between the ball 5 and the inner wall of the pen tip 3, facilitating the outward output of the ink.
[0028] Regarding the design of the adjusting spring 7 for adjusting the indentation of the ball 5, the front end of the adjusting spring 7 has a push rod 8. The push rod 8 passes through the pen bowl 6 and is connected to the ball 5. The design of the push rod 8 facilitates cooperation with the pen tip 3 having a smaller inner diameter. There is a spring seat 9 inside the pen tip 2. The spring seat 9 is detachably connected to the inside of the pen tip 2 by means of a threaded connection. The spring seat 9 has a through hole through which the ink passes. The rear end of the adjusting spring 7 is fitted with the spring seat 9. The adjusting spring 7 is restricted inside the pen tip 2 by the spring seat 9, and the spring seat 9 is fixed inside the pen tip 2 by the thread of the spring seat 9.
[0029] Through the design adjustment of the above structure, with the cooperation of the adjusting spring 7, when writing, the ball 5 retracts inward under the action of force extrusion, and a gap is formed between the ball 5 and the inner wall of the pen tip 3, and the ink flows out along the gap; when writing is completed, the external force on the ball 5 disappears, and the adjusting spring 7 pushes the ball 5 forward, reducing the gap between the ball 5 and the inner wall of the pen tip 3, and a closed space can be formed behind the ball 5, thus ensuring that the ink behind the ball 5 can remain non-drying. The ink remaining on the ball 5 forms a cured film, forming a protective film between the ball 5 and the inner wall of the pen tip 3, better increasing the sealing performance. When used again, the cured film formed by the residual ink on the ball 5 is rubbed off, and a gap is formed again between the ball 5 and the pen tip 3, and the ink is output along the gap.
[0030] Such a design avoids the volatilization and drying of the ink, not only reducing the deterioration of the writing experience caused by the drying of the ink, but also avoiding the reduction of the service life of the pen caused by the drying of the ink.
[0031] It is obvious to those skilled in the art that based on the above teaching content, certain modifications, combinations, and variations can also be made.
