[0063] In the embodiment, since the projection of the first scribing part 121 on the base 110 is arranged in a collinear manner with the projection of the second scribing part 131 on the base 110, the user makes the first upper end point 123 and the second upper end point 133 contact the paper at the same time by holding the pen, and the distance between the first upper end point 123 and the second upper end point 133 is L3. When the distance between the adjacent two lines of text on the current paper is adapted to the distance between the first upper end point 123 and the second upper end point 133, the user can mark the adjacent two lines of text at the same time by the current holding posture, thereby improving the work efficiency.

The first pen tip 120 and the second pen tip 130 are located at the intersection of the side surface 111 and the top surface 112, and extend towards the side surface 111 and the top surface 112, respectively. This results in the first drawing portion 121 and the second drawing portion 131 being obliquely arranged.

[0068] More preferably, the base 110 has a vent 113 on its side 111, and the vent 113 is located between the first pen refill 120 and the second pen refill 130 to ensure the balance of air pressure inside and outside the writing instrument and to achieve smooth discharge of fluorescent liquid.

[0069] The present invention also provides a writing instrument, comprising:

[0070] The pen tip has a housing 300, and a roll core 400 for storing fluorescent liquid is installed inside the housing 300, wherein the connector 200 in the pen tip is inserted into the roll core 400.

[0071] It is further noted that the housing 300 includes a detachably connected nib housing 310 and a barrel housing 320.

[0072] Example 2

[0073] like Figures 7 to 12 As shown, the present invention provides a pen tip capable of drawing lines of different widths, comprising:

[0074] The body 100 and the connector 200 connected to the body 100 transmit the fluorescent liquid to the body 100 through the connector 200, and the body 100 comprises a base 110 extending along the axial direction of the connector 200, and at least two pen cores are arranged at one end of the base 110, which are a first pen core 120 and a second pen core 130, wherein the first pen core 120 and the second pen core 130 are arranged on the two sides of the base 110 along the axial direction of the connector 200, and the first pen core 120 is provided with a first line marking part 121 for forming a line width L1, and the second pen core 130 is provided with a second line marking part 131 for forming a line width L2, the axial direction of the first pen core 120 and the axial direction of the connector 200 form a first preset angle α1, the axial direction of the second pen core 130 and the axial direction of the connector 200 form a second preset angle α2, and the line width L1 formed by the first line marking part 121 and the line width L2 formed by the second line marking part 131 are different.

[0075] The pen head provided by the utility model can draw lines with different widths, two pen cores are arranged on the base 110, the line width of the line marking part on each pen core is different, the line marking requirement in different scenes can be met, the two pen cores are arranged at the same end of the base 110, the user can conveniently switch, and the flexibility of the writing tool is improved.

[0076] It is worth mentioning that the angle of the first preset angle α1 and the second preset angle α2 is between 0° and 90°.

[0077] Preferably, the first pen core 120 is provided with two first surfaces 122, and a first common edge is formed between the two first surfaces 122, wherein each first surface 122 is defined by the contour edge of the first pen core 120 and the first common edge, and the first line marking part 121 is located at the first common edge of the two first surfaces 122; the second line marking part 131 is arranged at the end of the second pen core 130 and is arranged in a spherical shape.

[0078] Further preferably, the two first surfaces 122 are symmetrically arranged along the length direction of the first line marking part 121, and the angle between the two first surfaces 122 is between 0° and 180°.

[0079] In this embodiment, the included angle between the two first surfaces 122 is between 0° and 180°, making the first surfaces 122 inclined. The inclined surface allows the pen tip to better adapt to different writing angles, making writing smoother and more natural, and also adapting to different pen-holding postures. On the other hand, it reduces the obstruction of the pen tip to the line of sight, improving visibility during writing. Thirdly, it allows for better control of the speed and flow of fluorescent liquid, ensuring uniform distribution of fluorescent liquid during writing and avoiding interruptions or accumulation of liquid. Fourthly, the relatively rounded and smooth edges of the inclined surface reduce the friction between the pen tip and the paper, making the writing process smoother and reducing the risk of paper damage.

[0080] Furthermore, the first surface 122 is planar. This allows for a large amount of fluorescent liquid to be supplied to the first scribing portion 121 and the second scribing portion 131 when drawing lines, thereby improving the reliability of line drawing.

[0082] In this embodiment, the two ends of the drawing section have a height difference, allowing the user to achieve marking effects of different widths and intensities by changing the grip angle or pressure. This means that a single refill on the same highlighter can be used for highlighting fine lines or for covering large areas of text. This also improves the user experience and increases the product's durability.

[0083] More preferably, the extension line of the projection of the first scribed portion 121 onto the base 110 passes through the projection of the vertex 135 of the second scribed portion 131 onto the base 110, wherein the second scribed portion 131 is provided with a vertex 135, and there is a height difference between the first upper endpoint 123 on the first scribed portion 121 and the vertex 135 on the second scribed portion 131.

[0084] In this embodiment, since the projection of the first scribe portion 121 on the base 110 and the projection of the second scribe portion 131 on the base 110 are collinear, the user can make the first upper endpoint 123 and the vertex 135 simultaneously contact the paper by holding the pen, and the distance between the first upper endpoint 123 and the vertex 135 is L3. When the spacing between two adjacent lines of text on the current paper is adapted to the distance between the first upper endpoint 123 and the vertex 135, the user can mark two adjacent lines of text simultaneously by holding the pen, thereby improving work efficiency.

[0085] More preferably, the first scribed portion 121 includes a first arcuate surface, and the first arcuate surface protrudes in a direction away from the base 110, wherein the two sides of the first arcuate surface smoothly transition to the first surface 122 on the corresponding side.

[0086] In this embodiment, the tracing part is set as an arc surface, which can provide a smoother writing experience, ensure uniform distribution of fluorescent liquid, and protect the paper from damage, while improving the durability of the pen refill and the user experience.

[0087] Preferably, the base 110 is columnar and includes a side surface 111 and a top surface 112. The first pen tip 120 and the second pen tip 130 are located at the intersection of the side surface 111 and the top surface 112, and extend towards the side surface 111 and the top surface 112, respectively. This results in the first drawing portion 121 and the second drawing portion 131 being obliquely arranged.

[0088] More preferably, the base 110 has a vent 113 on its side 111, and the vent 113 is located between the first pen refill 120 and the second pen refill 130 to ensure the balance of air pressure inside and outside the writing instrument and to achieve smooth discharge of fluorescent liquid.

[0089] The present invention also provides a writing instrument, comprising:

[0090] The pen tip has a housing 300, and a roll core 400 for storing fluorescent liquid is installed inside the housing 300, wherein the connector 200 in the pen tip is inserted into the roll core 400.
