[0001] The utility model relates to the technical field of pens, in particular to a direct liquid acrylic pen with an ink stirring function. Background Art
[0002] In the field of painting, acrylic paint has become a popular material for many artists and art enthusiasts due to its unique properties, such as quick drying, vibrant and long-lasting colors, and strong covering power. With the continuous innovation and development of painting tools, direct-liquid acrylic pens are becoming increasingly popular. However, due to the high specific gravity of the pigment particles in acrylic paint, direct-liquid acrylic pens are prone to pigment sedimentation and uneven distribution when left unused for extended periods. This affects the consistency and saturation of the colors, making it difficult to achieve the desired effect.
[0003] To this end, the conventional solution is to place a steel ball inside the pen barrel, and use the steel ball to stir the ink by shaking the pen barrel, which can effectively deal with the problem of pigment sedimentation. However, this approach still has some defects in actual use. On the one hand, since the end of the water-introducing core of the straight liquid acrylic pen must be inserted into the ink storage cavity inside the pen barrel to draw ink, the steel ball will hit the end of the water-introducing core during movement, which can easily damage the water-introducing core and cause it to shift. On the other hand, the steel ball cannot reach the corner of the ink storage cavity inside the pen barrel during movement, and pigment is often more likely to precipitate in the corner of the ink storage cavity, so the stirring efficiency is not high and the stirring effect is poor. Therefore, it is necessary to improve the existing technology to overcome the defects in the existing technology. Utility Model Content

[0028] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0029] See Figures 1 to 7 The utility model provides a straight liquid acrylic pen with an ink stirring function, comprising: a pen body 1, an ink introduction component, a pen head component and a pen cap 7.
[0030] In the present invention, the pen barrel 1 can be but not limited to a cylindrical shape, with a closed upper end and an open lower end. An ink storage cavity 101 for storing ink is provided inside the pen barrel 1. The ink storage cavity 101 can be but not limited to a circular shape.
[0031] The ink introduction assembly includes a water reservoir 2 and a water introduction core 3. The water reservoir 2, which utilizes a conventional structure, is mounted within the open end of the penholder 1. An ink introduction hole 201 is defined in the center of the water reservoir 2. The water introduction core 3 is installed within the ink introduction hole 201 with an interference fit. An ink absorbing portion 301 is located at the top of the water introduction core 3. This portion protrudes from the top of the water reservoir 2 and is immersed in the ink within the ink storage chamber 101.
[0032] For example, the material of the water guide core 3 may be polyester fiber, acrylic fiber or POM microporous plastic.
[0033] The nib assembly is mounted on the open end of the pen barrel 1 and presses the water reservoir 2 , and the pen cap 7 is sleeved on the pen barrel 1 to seal the nib 5 of the nib assembly to prevent the ink from volatilizing and drying up.
[0034] See Figure 2 and Figure 4 A stirring member 4 is mounted within the ink reservoir 101. This member is tubular with a defined wall thickness, specifically a circular tube in this embodiment. The outer circumference of the stirring member 4 is loosely aligned with the inner wall of the pen barrel 1, and the diameter of the stirring member 4 is larger than the diameter of the water-drawing core 3. The stirring member 4 is able to freely move within the ink reservoir 101 to stir the ink therein. However, due to the inner wall of the pen barrel 1, the stirring member 4 does not come into contact with the water-drawing core 3 during its movement.
[0035] When the direct-liquid acrylic paint brush is shaken, the stirring member 4 moves up and down along the inner wall of the ink reservoir 101. Not only can the stirring member 4 reach the corners of the ink reservoir 101 to agitate any pigment particles that have settled there, but as the stirring member 4 moves up and down, the ink in the ink reservoir 101 can simultaneously flow through the inner hole of the stirring member 4 and the gap between the stirring member 4 and the inner wall of the pen barrel 1, thereby greatly improving the stirring efficiency and effect. Furthermore, the stirring member 4 avoids the ink-absorbing portion 301 of the water-drawing core 3 during movement, effectively preventing damage to the water-drawing core 3 and ensuring the service life of the direct-liquid acrylic paint brush.
[0036] Preferably, the gap between the stirring member 4 and the inner wall of the pen barrel 1 is 0.2mm-1mm; the length of the stirring member 4 is greater than the inner diameter of the pen barrel 1 to control the stirring member 4 from flipping over in the pen barrel 1 and prevent it from colliding with the water guide core 3.
[0037] Preferably, the stirring member 4 is made of metal, such as stainless steel or chrome-plated iron, which is heavy, easy to shake, and not easily corroded.
[0038] See Figure 6 The pen body 1 is provided with a plurality of arc-shaped ribs 102 along the axial direction on the inner wall of the ink storage chamber 101. The plurality of ribs 102 are distributed in a circular shape with equal intervals. When the straight liquid acrylic pen is shaken, the stirring member 4 moves up and down along the surface of the ribs 102.
[0039] See Figure 4 and Figure 5 The pen tip assembly includes a pen tip 5 and a joint 6. The pen tip 5 is fixedly mounted on the joint 6 and elastically abuts against the water guide core 3.
[0040] In this embodiment, the material used for the pen tip 5 can be nylon fiber, polyester fiber, acrylic fiber or PE sintered material.
[0041] The lower end of the water-drawing core 3 is provided with an ink-drawing portion 302 for contacting the nib 5. Both the ink-drawing portion 302 and the ink-absorbing portion 301 are conical and symmetrically arranged. By utilizing a conical shape for the ink-drawing portion 302, the present invention facilitates greater elastic deformation, reducing the assembly precision requirements for the water-drawing core 3 and ensuring reliable contact between the water-drawing core 3 and the nib 5, thereby ensuring that the water-drawing core 3 can continuously guide the flow of ink to the nib 5. By also designing the ink-absorbing portion 301 as conical and symmetrical with the ink-drawing portion 302, the present invention eliminates the need to distinguish the orientation of the water-drawing core 3 during assembly, further facilitating assembly.
[0042] See Figure 5 A mounting hole 601 is provided in the middle of the connector 6, which passes through the upper and lower ends thereof. A hook 602 is provided along the inner wall of the mounting hole 601. The pen tip 5 is located near the upper end thereof and is provided with an annular groove 501 along the outer circumference. The upper end of the pen tip 5 is inserted into the mounting hole 601 and the hook 602 is engaged with the annular groove 501, which can effectively prevent the pen tip 5 from falling out of the connector 6.
[0043] Furthermore, a first step 103 is provided on the inner wall of the pen barrel 1 near the open end. The first step 103 can be regarded as formed by the enlargement of the inner diameter of the open end of the pen barrel 1. The upper end of the water reservoir 2 rests on the first step 103. A first convex ring 202 is provided at the lower end of the water reservoir 2. A second convex ring 603 is provided at the top of the connector 6. The first convex ring 202 is inserted into the second convex ring 603 and is tightly connected to each other. In addition, a third convex ring 604 is provided at the top of the connector 6, which is concentrically sleeved on the outside of the second convex ring 603. The third convex ring 604 is inserted into the open end of the pen barrel 1 and is tightly connected to each other. A second step 605 is provided on the outer circumferential surface of the connector 6. The second step 605 rests on the end face of the pen barrel 1. The present invention adopts the above-mentioned structure to achieve fixed assembly of the connector 6, the water reservoir 2 and the pen barrel 1, making assembly simpler and more convenient.
[0044] It can be seen that the direct liquid acrylic pen with ink stirring function of the present invention has a tubular stirring member 4 installed in the ink storage chamber 101 of the pen body. During the shaking of the direct liquid acrylic pen, the stirring member 4 can move up and down along the inner wall in the ink storage chamber 101. The stirring member 4 can not only reach the corner position of the ink storage chamber 101 to stir the pigment particles settled in the corner position, but also when the stirring member 4 moves up and down, the ink in the ink storage chamber 101 can simultaneously flow from the inner hole of the stirring member 4 and the gap between the stirring member 4 and the inner wall of the pen body 1, thereby greatly improving the stirring efficiency and stirring effect; at the same time, the stirring member 4 can avoid the ink absorbing part 301 of the water guide core 3 during the movement, which can effectively prevent the water guide core 3 from being damaged, thereby ensuring the service life of the direct liquid acrylic painting pen.
