Description

Technical Field

[0001] This utility model relates to the field of marker technology, and in particular to a marker with a novel ink control structure. Background Technology

[0002] Markers are widely used in writing and drawing due to their rich colors, stroke effects, and ease of use;

[0003] Most existing direct-ink markers use a conical ink control structure, which has the following drawbacks:

[0004] 1. High precision requirements for molds lead to high mold costs;

[0005] 2. Insufficient leak resistance (generally below -20 kPa);

[0006] 3. Poor stability of the air return channel leads to poor ink output.

[0007] Therefore, there is an urgent need to design a new type of ink control structure for markers that is low in manufacturing cost, highly leak-proof, and has stable air return. Utility Model Content

[0008] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0018] The cross-section of the water-guiding core is circular. The water-guiding core is interference-fitted with the polygonal side of the ink control hole and clearance-fitted with the polygonal corner of the ink control hole.

[0019] The corner gap between the water inlet core and the ink control hole forms a return air channel.

[0020] Preferably, the pen tip and the ink core are integrally molded structures;

[0021] An annular insertion hole is formed between the ink absorber and the water guide core for inserting the ink guide section.

[0022] Preferably, the valve seat and the ink guide section are integrally molded.

[0023] Preferably, the ink control cavity is provided with an annular step whose inner diameter gradually decreases towards the ink outlet.

[0024] Preferably, the ink absorber is a flexible fiber with dense pores, and the pen tip and ink core are respectively inserted into the interior of the ink absorber.

[0042] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0043] like Figure 1-5As shown, a novel ink-controlling marker pen includes a pen barrel 1, a pen tip 2, an ink-absorbing body 3, an ink-controlling component, a pen nib 4, and an ink-guiding core 8. The pen barrel 1 is provided with an ink storage cavity 10, and one of its open ends is airtightly connected to the pen tip 2.

[0044] The ink control assembly includes an ink control valve body 5;

[0045] One end of the pen tip 2 is provided with an ink control valve body 5, and the other end is provided with a pen tip 4;

[0046] An ink-absorbing body 3 for absorbing liquid ink is provided between the ink control valve body 5 and the pen tip 4.

[0047] The ink control valve body 5 includes a valve seat 51 and an ink guide section 52. The ink control valve body 5 is airtightly connected to the pen tip 2 through the valve seat 51.

[0048] The valve seat 51 is provided with an ink control cavity 20, one end of which is provided with an ink inlet hole 51a communicating with the ink storage cavity 10, and the other end of the ink outlet hole 51b is provided with an ink guide section 52 that is inserted into the ink absorber 3.

[0049] The ink guiding section 52 is provided with an ink control hole 30 with a polygonal cross-section;

[0050] The ink control hole 30 is provided with a water-guiding core 8 for introducing liquid ink into the ink absorber 3; the cross-section of the water-guiding core 8 is circular, and the water-guiding core 8 is interference-fitted with the polygonal side of the ink control hole 30 and clearance-fitted with the polygonal corner of the ink control hole 30.

[0051] The corner gap between the water inlet core 8 and the ink control hole 30 forms a return air channel 40.

[0052] In this embodiment, with the pen tip 2 sealed to the ink control valve body 5 and the pen barrel 1, the leakage resistance is improved by interference fit between the water inlet core 8 and the polygonal side 301 of the ink control hole 30, allowing it to withstand -40Kpa without leakage. At the same time, the gap fit between the water inlet core 8 and the polygonal corner 302 of the ink control hole 30 creates a sufficient air return channel 40, ensuring smooth ink flow. Compared with the existing serpentine ink control structure, this polygonal ink control structure has a lower manufacturing cost and improves leakage resistance while ensuring smooth ink flow.

[0053] Furthermore, such as Figure 2 As shown, in order to resist the impact of falling and prevent the pen tip 4 and the water-guiding core 8 from separating when falling, and to ensure the ink output effect and leakage resistance, the pen tip 4 and the water-guiding core 8 are integrally molded structures; an annular insertion hole 50 is formed between the ink-absorbing body 3 and the water-guiding core 8 for inserting the ink guide section 52.

[0054] In this embodiment, the annular insertion hole 50 facilitates the insertion of the ink guide section 52 into the ink absorber 3, ensuring consistent processing.

[0055] Furthermore, such as Figure 2 , 5 As shown, in order to reduce manufacturing costs and difficulties and improve the overall reliability of the ink control valve body 5, the valve seat 51 and the ink guide section 52 are integrally molded.

[0056] Furthermore, such as Figure 2 , 5 As shown, in order to prevent ink from directly impacting the ink guide section 52 and improve the anti-leakage performance, the ink control cavity 20 is provided with an annular step 6 whose inner diameter gradually decreases towards the ink outlet hole 51b.

[0057] Furthermore, in order to improve the capillary conduction effect of the ink and enhance its anti-leakage performance, the ink absorber 3 is a flexible fiber with dense pores, and the pen tip 4 and the ink core 8 are respectively inserted into the interior of the ink absorber 3; the fiber can be natural fiber or chemical fiber, such as cotton, polyester fiber, etc.

[0058] Furthermore, in order to quickly absorb excess spilled ink under negative pressure, high temperature, and transportation conditions, thereby improving leak resistance, the ink-absorbing body 3 is absorbent cotton.

[0059] Furthermore, in order to meet the requirements of different types of inks and expand the scope of application, the cross-section of the ink control hole 30 can be a polygonal structure such as a quadrilateral or hexagon.

[0060] Furthermore, such as Figure 1 , 2 As shown, in order to protect the pen tip 4, a pen cap 7 is provided on the outside of the pen tip 4 to cover the pen tip 4, and the pen cap 7 is detachably connected to the pen tip 2 or the pen barrel 1.

[0061] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
