[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] like Figure 1 As shown, an oval marking pen comprises:

[0023] The pen cap color cover 1, the oval design is used to form a cross-symmetrical relationship with the bottom color cover;

[0024] The pen core 2 is used as an ink flow channel for writing;

[0025] The upper pen holder 3 is used for embedded clamping of the pen core, and the inner part is hollow to accommodate the ink bag;

[0026] An ink bag 4, used for storing ink;

[0027] The pen cap 5 is used to protect the pen core from being exposed to the external environment to avoid contamination and damage;

[0028] The lower pen holder 6 is used to extend the length of the pen holder for easier holding;

[0029] The bottom color cover 7 is used to display the ink color to facilitate the selection of the desired color;

[0030] The pen cap 5 is a hollow structure, and the pen cap color cover 1 is embedded and snap-fitted with the pen cap 5. The pen cap has an elliptical appearance that gradually changes to a circular appearance from the top to the bottom insertion hole. A buckle is set at the insertion hole, and the upper pen rod is spirally inserted into the inside of the pen cap and snap-fitted through the buckle.

[0031] Furthermore, a reserved hole 8 is hollowly arranged at the top of the upper pen shaft 3, and the pen core 2 is embedded and clamped; the pen core 2 is a cylindrical fiber body at the top extending from the upper pen shaft reserved hole 8, and the bottom is a conical fiber body. The bottom of the pen core is inserted into the ink sac cavity 4 to form a low-pressure area inside the cavity. The ink is attracted to rise by the capillary tension of the fiber body of the pen core 2 and fills the entire pen core 2. The capillary surface tension and pressure are balanced, and the ink stops flowing.

[0032] Furthermore, an ink sac cavity 4 is provided inside the upper pen shaft 3, and the upper pen shaft 3 has a hollow tubular structure shell. The ink sac 4 cavity is not connected to the inner wall of the upper pen shaft, but is only connected to the top of the upper pen shaft 3; the appearance of the upper pen shaft 3 adopts an elliptical appearance that gradually changes to a circular appearance at the bottom. The elliptical shell is provided to facilitate the stability of the pen shaft by fingers, and improve the instability of the circular pen shaft when the pen shaft is held and rotated.

[0033] Furthermore, the ink sac cavity 4 is filled with Uni POSCA marker ink, which has excellent color stability, and the ink is easy to flow out from the pen tip without interruption or blockage, ensuring a smooth writing experience.

[0034] Furthermore, a male buckle 9 is provided at the bottom of the upper pen shaft 3, and a female buckle 10 is provided at the top of the lower pen shaft 6. The male buckle 9 is convex and the female buckle 10 is concave. The tops of the male buckle 9 and the female buckle 10 are designed with chamfers to guide the snapping action. The connection between the upper pen shaft 3 and the lower pen shaft 6 adopts a double groove interlocking design. In the docking assembly, the lower pen shaft is used to fix the product assembly at the double groove of the upper pen shaft, increase the contact area of ​​the connection, make the connection more firm, and make the overall structure of the pen more stable. Reduce the loose space between the upper pen shaft 3 and the lower pen shaft 6, improve the stability of the pen shaft, and reduce the shaking or loosening caused by long-term use. The overall structure of the marking pen is more solid and the flexural strength is significantly improved. The pen shaft is not easy to break or deform when subjected to greater force or extrusion during use; increase the stability of the pen shaft, reduce the friction between the upper pen shaft 3 and the lower pen shaft 6, reduce the wear of the pen shaft connection due to frequent use, extend the service life of the marking pen, and facilitate disassembly.

[0035] Furthermore, the bottom of the lower pen shaft 6 is hollow, and the bottom color cover 7 is embedded and clamped into the lower pen shaft 6. The outer shell of the lower pen shaft gradually changes from a circular appearance at the top to an elliptical appearance at the bottom to prevent the marking pen from rolling when placed on the desktop. The appearance color of the bottom color cover 7 is consistent with the color of the ink sac 4, and the color of the marking pen is determined when the pen cap 5 is buckled on the upper pen shaft 3.

[0036] In a specific embodiment, polyetheretherketone (PEEK) engineering plastic is selected as the outer shell material of the upper pen body 3, the pen cap 5, and the lower pen body 6. Polyetheretherketone (PEEK) has excellent oxidation resistance, so that the marking pen is not easy to oxidize, become brittle or break during long-term use; it has high toughness and strength, and is not easy to break even when impacted or twisted. When the marking pen falls, it absorbs the impact force to reduce the possibility of pen damage, resists friction and wear, and maintains a good appearance without deformation during long-term use.
