Description

Technical Field

[0001] This utility model relates to the field of marker technology, specifically to a direct-liquid 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 nib through direct contact, but this can easily lead to excessive ink flow and leakage. Furthermore, the nib and barrel of direct-liquid markers have a gap fit; excessive ink flowing into the wick can create negative pressure during writing, resulting in leakage. Both of these factors affect the use of the markers. In addition, improper storage conditions can cause ink sedimentation, leading to poor ink flow or even ink interruption. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a direct-liquid marker.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A direct-liquid marker pen, comprising a pen shell, characterized in that the pen shell contains, from top to bottom, a steel ball, a channel chamber, a piston, a telescopic spring, a transition connector, a cotton wick, and a pen tip;

[0006] The pen shell and the channel chamber are fitted together to form an ink storage chamber, which is located above the channel chamber, and the steel ball is placed inside the ink storage chamber.

[0007] The channel chamber and the transition connector are detachably connected to form an ink transition chamber. The top of the channel chamber has an ink channel with open ends, which is hourglass-shaped. A piston and a telescopic spring are installed inside the ink transition chamber. The telescopic spring is mounted on the transition connector. The piston includes a plug body and a plug rod. The plug body is mounted on the telescopic spring, and the upper surface of the plug body fits against the lower open end of the ink channel. The plug rod passes through the middle straight section of the ink channel and extends into the ink storage chamber.

[0008] The steel ball effectively prevents ink settling and avoids ink skipping in the marker. The valve-like structure described above effectively controls ink flow, preventing excessive ink from flowing into the wick and causing leakage. The funnel-shaped opening at the bottom of the ink channel allows ink to flow more quickly into the ink transfer chamber. The ink transfer chamber is designed to both store excess ink and ensure the wick has sufficient ink.

[0009] Preferably, the side of the plug away from the telescopic spring is a frustum, with a short cylinder below the frustum and a long cylinder below the short cylinder. The diameter of the long cylinder is smaller than that of the short cylinder, and the long cylinder can be nested inside the telescopic spring. The plug is supported on the telescopic spring through the edge of the long cylinder.

[0010] Preferably, the channel body is threadedly connected to the transition connector.

[0011] Preferably, the diameter of the straight section in the middle of the ink channel is 2-6 mm.

[0012] Preferably, the pen shell and the channel chamber are fitted together to form an ink storage chamber, which is located above the channel chamber.

[0013] Preferably, an island is provided on the inner side wall of the transition connector, and the telescopic spring is mounted on the island.

[0014] Preferably, the lower part of the transition connector is located inside the cotton core, and the transition connector has a cotton core liquid absorption channel with open ends arranged longitudinally inside.

[0015] Preferably, the inner diameter of the liquid absorption channel inside the cotton core is smaller than the rest of the channel. The smaller inner diameter can prevent the ink from being absorbed by the cotton core too quickly and in excessive amounts.

[0016] Preferably, the marker also includes a pen tip sleeve, which is detachably nested with the pen shell, and a transition connector is mounted on the pen tip sleeve.

[0017] Preferably, the pen tip sleeve is threadedly connected to the pen shell.

[0018] Preferably, the marker also includes a cap that is fitted over the outside of the pen tip.

[0019] This invention provides a direct-flow marker pen. The marker pen's ink reservoir contains a steel ball for stirring the ink to prevent it from agglomerating and settling, ensuring smooth ink flow. The pen barrel's channel chamber, steel ball, piston, telescopic spring, and transition connector work together to form a valve-like structure, which controls the opening and closing of the ink channel within the channel chamber, thereby controlling the ink flow to the wick and preventing the ink from flowing to the wick too quickly. At the same time, the ink transition chamber ensures that the wick has sufficient ink. Attached Figure Description

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

[0025] like Figure 1-3 As shown, a direct-liquid marker pen includes a pen shell 1, a pen tip sleeve 8, and a pen cap 9. The pen tip sleeve 8 is threadedly connected to the pen shell 1 to form a complete pen barrel, and the pen cap 9 is fitted onto the pen tip sleeve 8 by a snap-fit ​​connection.

[0026] like Figure 2 As shown, the pen barrel contains, from top to bottom, a steel ball 10, a channel chamber 2, a piston 3, a telescopic spring 4, a transition connector 5, a cotton wick 6, and a pen tip 7. The pen shell 1 and the channel chamber 2 together form an ink reservoir 11, which is located above the channel chamber 2, with the steel ball 10 placed inside. Both the channel chamber 2 and the transition connector 5 are hollow components. The top of the channel chamber 2 has a longitudinally arranged ink channel 21 with open ends, shaped like an hourglass. The channel chamber 2 and the transition connector 5 are connected by threads to form an ink transition chamber 42. The piston 3 and the telescopic spring 4 are located inside the ink transition chamber 42. The telescopic spring 4 is mounted on an island 51 on the inner wall of the transition connector 5, and the piston 3 is partially mounted on the telescopic spring 4 and partially filled in the ink channel 21. Specifically, the piston 3 includes a piston body 31 and a piston rod 32. The side of the piston body 31 away from the telescopic spring 4 is a frustum. A short cylinder is set below the frustum, and a long cylinder is set below the short cylinder. The diameter of the long cylinder is smaller than that of the short cylinder. The long cylinder can be nested inside the telescopic spring 4. The piston body 31 is supported on the telescopic spring 4 through the edge of the long cylinder. The upper surface of the frustum of the piston body 31 fits against the lower opening of the ink channel 21. The piston rod 32 passes through the middle straight section of the ink channel 21 and extends partially into the ink reservoir 11.

[0027] The lower part of the transition connector 5 is located inside the cotton core 6. The transition connector 5 has a longitudinally arranged cotton core absorbent channel 52 with open ends, and this channel is wider at the top and narrower at the bottom. Specifically, the inner diameter of the cotton core absorbent channel 52 located inside the cotton core 6 is smaller than the rest of the channel. The upper part of the pen tip 7 is located inside the cotton core 6, and the lower part is exposed outside the pen tip sleeve 8.

[0028] The working principle of the valve-type direct-liquid marker is as follows: In its natural state, under the force of the telescopic spring 4, the piston 3's stop rod 32 passes through the middle straight section of the ink channel 21 and extends into the ink reservoir 11. Shaking the marker up and down causes the steel ball 10 to move with it, stirring the ink. Simultaneously, the telescopic spring 4 repeatedly extends and retracts under the combined force of the shaking and the steel ball 10, and the piston 3 also moves axially back and forth. When the stop rod 32 leaves the ink channel 21, the ink in the ink reservoir 11 can flow into the ink transition chamber 42 through the ink channel 21. Because the lower part of the transition connector 5 is located inside the wick 6, the wick 6 can absorb the ink in the ink transition chamber 42. After maximizing ink absorption, the wick 6 expands and seals the lower port of the ink transition chamber 42. The ink transition chamber 42 not only supplies ink to the wick 6 but also stores excess ink, thus ensuring a continuous ink supply. Furthermore, the valve-like structure formed by the steel ball 10, the channel chamber 2, the piston 3, the telescopic spring 4, and the transition connector 5 can prevent excessive ink flow to the cotton core 6.

[0029] 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.
