Description

Technical Field

[0001] This utility model relates to the field of marker technology, and more specifically, to a direct-liquid acrylic marker. Background Technology

[0002] Acrylic markers are pens specifically designed for painting with acrylic or polymer paints. Using acrylic resin as the pigment, they offer excellent coverage and drawing ability, thus receiving widespread acclaim. Direct-liquid acrylic markers, due to their inherent characteristics, have a hollow ink chamber where all the pigment is stored. Ink is delivered to the pen tip through direct contact, but this can lead to leakage or ink interruptions. Typically, direct-liquid markers have a gap between the pen tip and the barrel; excessive ink flow to the tip can create negative pressure during writing, resulting in leakage. Both of these factors affect the use of the markers. Furthermore, improper storage conditions can cause ink sedimentation, leading to poor ink flow or even ink interruptions.

Therefore, they should not be construed as limitations on this application.

[0026] like Figure 1-4 As shown, a direct-liquid acrylic marker includes a cap 1, a center connector 2, an inner plug 3, a barrel 4, a tip 5, a core 6, a sponge 7, and a ball bearing 8. The barrel 4, center connector 2, and cap 1 are sequentially connected to form the marker housing, with the remaining components housed inside the housing.

[0027] The outer wall of the middle connector 2 is provided with an annular boss 21. The portion of the middle connector 2 above the annular boss 21 is fitted inside the pen barrel 4, with the bottom end face of the pen barrel 4 contacting the upper end face of the annular boss 21. The portion of the middle connector 2 below the annular boss 21 is fitted inside the pen cap 1, with the top end face of the pen cap 1 contacting the lower end face of the annular boss 21. The middle connector 2 and the pen barrel 4 are interference-fitted, and the interference-fitted walls are designed with approximately wavy, concave-convex surfaces. The two wavy surfaces cooperate to fix and position the middle connector 2 and the pen barrel 4. The middle connector 2 and the pen cap 1 are also interference-fitted through wavy, concave-convex surfaces, thereby fixing and positioning the middle connector 2 and the pen cap 1.

[0028] The inner connector 2 is hollow inside. The top of the inner plug 3 is also press-fitted to the inside of the pen barrel 4 via a corrugated wall. The lower part of the inner plug 3 extends into the interior of the inner connector 2. The inner plug 3 divides the interior of the pen barrel 4 into an ink reservoir 9, which is located above the inner plug 3. A steel ball 8 is installed in the ink reservoir 9, which can prevent acrylic ink from settling by shaking the steel ball 8. The inner plug 3 is hollow inside, and the ink guide 6 extends from the interior of the inner plug 3 into the interior of the inner connector 2. The ink guide 6 is designed as a stepped shaft, with a first shoulder 61 on the outer wall. The bottom end face of the inner plug 3 connects to the first shoulder 61 to prevent acrylic ink from flowing out of the inner plug 3 and into the interior of the inner connector 2. The pen tip 5 extends from the interior of the inner connector 2 to the outside of the bottom end of the inner connector 2, and the top of the pen tip 5 abuts against the bottom of the ink guide 6.

[0029] The inner plug 3 has several circumferentially arranged protrusions 31 on its outer side wall, and the bottom end faces of the protrusions 31 form a third annular boss 311. The inner side wall of the middle connector 2 has several axially arranged protrusions 22, the top end faces of the protrusions 22 forming a first annular boss 221 and the bottom end faces forming a second annular boss 222. The sponge 7 is disposed between the third annular boss 311 and the first annular boss 221, and the upper and lower end faces of the sponge 7 are respectively connected to the end faces of the two side bosses, thereby preventing the sponge 7 from shifting. The sponge 7 is tubular, extending from the lower end of the inner plug 3 to the upper end of the pen tip 5. The lower end of the inner plug 3, the water guide 6, and the upper end of the pen tip 5 are disposed inside the sponge 7. Therefore, the sponge 7 not only further prevents the inner plug 3, the water guide 6, and the pen tip 5 from shifting, but also fills the empty space inside the middle connector 2. The upper middle part of the outer side wall of the pen tip 5 is provided with a third shoulder 51, and the lower middle part is provided with a second shoulder 52. The third shoulder 51 of the pen tip 5 is connected to the first annular boss 221, and the second shoulder 52 is connected to the second annular boss 222, thereby positioning the pen tip 5.

[0030] The above description of embodiments of the present invention, through which those skilled in the art are able to implement or use the present invention, will be readily apparent to those skilled in the art. Various modifications to these embodiments will be readily apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novelty disclosed herein.
