Description

Technical Field

[0001] This utility model relates to the field of marker technology, specifically to a valve-type 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 valve-type direct-liquid marker.

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

[0005] A valve-type direct-liquid marker pen includes a pen shell. The pen shell contains, from top to bottom, a channel chamber, a valve ball, a telescopic spring, a transition connector, a wick, and a pen tip. The channel chamber and the transition connector are detachably connected to form an ink transition chamber. The top of the channel chamber has a longitudinally arranged ink channel with open ends. The valve ball and the telescopic spring are disposed within the ink transition chamber. The telescopic spring is mounted on the transition connector, and the valve ball is positioned between the telescopic spring and the ink channel. The valve ball can fill the lower open end of the ink channel to block ink flow. This valve structure effectively controls the ink flow rate, preventing excessive ink flow to the wick and leakage. The ink transition chamber design both stores excess ink and ensures sufficient ink for the wick.

[0006] Preferably, the pen casing and the channel chamber are fitted together to form an ink reservoir, which is located above the channel chamber and contains a stirring steel ball. The steel ball effectively prevents ink settling and avoids ink skipping in the marker.

[0007] Preferably, the ink channel is hourglass-shaped, meaning that both ends of the ink channel are funnel-shaped. The funnel-shaped openings at both ends of the ink channel better accommodate steel balls, such as valve steel balls, allowing them to better fit the lower opening of the ink channel and thus seal the outlet of the channel at the lower opening.

[0008] Preferably, the channel body is threadedly connected to the transition connector.

[0009] Preferably, the diameter of the straight section in the middle of the ink channel is 2-6 mm.

[0010] Preferably, an island is provided on the inner side wall of the transition connector, and the telescopic spring is mounted on the island.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] Preferably, the pen tip sleeve is threadedly connected to the pen shell.

[0015] Preferably, the marker also includes a cap that is fitted over the outside of the pen tip.

[0016] This invention provides a valve-type direct-ink marker. The marker's channel chamber, valve ball, telescopic spring, and transition connector work together to form a valve-like structure, controlling the opening and closing of the ink channel within the channel chamber. This controls the ink flow to the wick and prevents excessively rapid ink flow. Simultaneously, the ink transition chamber ensures sufficient ink for the wick. Furthermore, the marker's ink reservoir can be equipped with a stirring ball to agitate the ink, preventing aggregation and sedimentation, and ensuring smooth ink flow. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0022] like Figure 1-3 As shown, a valve-type 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 sleeved on the outside of the pen tip sleeve 8 by a snap-fit ​​connection.

[0023] like Figure 2 As shown, the pen barrel contains, from top to bottom, a stirring steel ball 10, a channel chamber 2, a valve steel ball 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, located above the channel chamber 2, with the stirring 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 valve steel ball 3 and the telescopic spring 4 are located within 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 valve steel ball 3 is positioned between the telescopic spring 4 and the ink channel 21. In its natural state, the valve steel ball 3 fills the lower open end of the ink channel 21, blocking ink flow.

[0024] The outer wall of the transition connector 5 is provided with a flange 53, and the transition connector 5 is mounted on the top of the pen tip sleeve 8 via the flange 53. The lower part of the transition connector 5 is located inside the cotton wick 6, and the transition connector 5 has a longitudinally arranged cotton wick absorbent channel 52 with open ends. The channel is wider at the top and narrower at the bottom. Specifically, the inner diameter of the cotton wick absorbent channel 52 located inside the cotton wick 6 is smaller than the rest of the channel. The upper part of the pen tip 7 is located inside the cotton wick 6, and the lower part is exposed outside the pen tip sleeve 8.

[0025] The working principle of the valve-type direct-liquid marker is as follows: In its natural state, the valve ball 3, under the force of the telescopic spring 4, fills the lower opening of the ink channel 21 to block the ink. Shaking the marker up and down causes the stirring ball 10 to move with the marker, stirring the ink; simultaneously, the telescopic spring 4 repeatedly extends and retracts, and the valve ball 3 moves axially back and forth. When the valve ball 3 leaves the lower opening of 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 cotton core 6, the cotton core 6 can absorb the ink in the ink transition chamber 42. After maximizing the absorption of ink, the cotton core 6 expands and seals the lower port of the ink transition chamber 42. The ink transition chamber 42 not only delivers ink to the cotton core 6 but also stores excess ink, thus ensuring a continuous ink supply. Furthermore, the valve-like structure formed by the channel chamber 2, valve ball 3, telescopic spring 4, and transition connector 5 prevents excessive ink from flowing into the cotton core 6.

[0026] 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.
