Description

Technical Field

[0001] This utility model relates to the field of writing instruments, specifically to a multi-color highlighter pen. Background Technology

[0002] Highlighters are primarily used for marking. A thicker, lighter ink is used to cover key areas to make marks, ensuring the text is clearly visible without obscuring it. In daily use, because the text to be marked varies, users need to leave different colored marks for easy retrieval and memorization. While using multiple highlighters of different colors can meet user needs, it also increases the burden of carrying them and creates situations where replacements need to be found.

[0003] Currently, some existing highlighters also have multi-color structures, such as the common side-by-side multi-color highlighters on the market. These mainly have multiple ink outlets at one end of the pen with pen tips inserted, allowing different inks to be output through the corresponding pen tips. However, due to the multiple pen tips, the pen tip diameter is relatively large, which can affect the field of vision for viewing writing marks to some extent. Increasing the exposed length of the pen tip can reduce the impact of the pen tip on the field of vision, but it also increases the risk of leaving marks due to accidental pen tip contact. At the same time, pressing the pen tip against the writing surface during writing also increases the risk of the pen tip being broken or damaged due to improper force, especially when a thin, wide-tipped pen tip is used due to space limitations. Utility Model Content

[0004] The purpose of this invention is to provide a multi-color highlighter that can meet the user's needs for marking with different colors, while ensuring the lifespan of the pen and reducing waste.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0024] See Figures 1-7This embodiment provides a multi-color highlighter pen, including a pen barrel 1 and two ink cartridge assemblies 2 for writing. The pen barrel 1 is a tubular structure with openings at both ends, and the two ink cartridge assemblies 2 are respectively inserted into and detachably connected to the openings at both ends of the pen barrel 1.

[0025] The ink cartridge assembly 2 includes an ink storage component 3 and three writing units 4. The ink storage component 3 can be inserted into and detachably connected to the pen barrel 1. The ink storage component 3 is a hollow structure with one end open and the other end closed. The cavity of the ink storage component 3 is divided by a first partition 31 to form several ink storage chambers 32. The number of ink storage chambers 32 is the same as the number of writing units 4. A closed head 5 is inserted into and detachably connected to the opening of the ink storage component 3. The closed head 5 is a hollow structure with both ends open, and its cavity is divided by a second partition 51 to form ink outlet chambers 52 corresponding to the ink storage chambers 32. The ink outlet chambers 52 are connected to the ink storage chambers 32 to form a receiving space 6 for accommodating the writing units 4. Each writing unit 4 is arranged at an equal angle relative to the central axis of the pen barrel 1. The ink color output by each writing unit 4 on the two ink cartridge assemblies 2 is different.

[0026] When in use, users can select different writing units 4 to mark with different colors of ink according to the marking needs. When the ink in the ink cartridge assembly 2 is used up, the ink cartridge assembly 2 can be removed from the pen barrel 1 and replaced with a new ink cartridge assembly 2 for use, which extends the life of the highlighter and reduces waste.

[0027] To reduce the risk of ink mixing of different colors due to leakage in different ink-containing spaces 6, a protrusion 33 is provided on the end face of the first partition 31, and a slot 53 adapted to the protrusion 33 is provided on the second partition 51. When the sealing head 5 is installed on the ink storage component 3, the first partition 31 and the second partition 51 abut against each other, and the protrusion 33 is located in the slot 53. A rubber sheet can be embedded in the slot 53 to further improve the sealing between the sealing head 5 and the ink storage component 3, increasing the difficulty of ink leakage in the containing space 6, thereby ensuring the accuracy of the writing color and the writing effect.

[0028] In this embodiment, the ink reservoir 3 and the pen barrel 1, as well as the ink reservoir 3 and the sealing head 5, can be connected by a snap-fit ​​structure.

[0029] See Figure 1 The ink cartridge assembly 2 is fitted with and detachably connected to a pen cap 7. The pen cap 7 is made of transparent material, allowing the user to see the color of the writing without removing the pen cap 7, which improves the convenience of use. Either of the two pen caps 7 is provided with a pen clip 71, which not only makes it convenient to hold the highlighter in place, but also restricts the highlighter from rolling, reducing the risk of the highlighter falling from a height and being damaged due to rolling.

[0030] In this embodiment, the pen cap 7 and the ink cartridge assembly 2 can be detachably connected through a snap-fit ​​structure.

[0031] See Figures 3-6 The writing unit 4 includes an adjuster 41 and a pen tip 42. The adjuster 41 is inserted into and detachably connected to the ink storage component 3. The ink storage component 3 is located in the ink storage cavity 32. The adjusters 41 of each writing unit 4 are arranged at equal angles around the central axis of the ink storage component 3. The pen tip 42 is inserted into and detachably connected to the sealing head 5. The pen tip 42 is located in the ink outlet cavity 52. ​​The pen tips 42 of each writing unit 4 are arranged at equal angles around the central axis of the sealing head 5. When the sealing head 5 is installed on the ink storage component 3, the inner end of the pen tip 42 is inserted into the adjuster 41. By separately assembling the adjuster 41 on the ink reservoir 3 and the pen tip 42 on the sealing head 5, the components can be pre-assembled. After ink is injected into the ink reservoir 32 on the ink reservoir 3, the sealing head 5 can be directly assembled for sealing, reducing the risk of ink leakage due to improper assembly. At the same time, the corresponding settings of the adjuster 41 and pen tip 42 on the ink reservoir 3 and the sealing head 5 ensure the stability of a single output path for inks of different colors, ensuring the user's needs for writing in different colors.

[0032] In this embodiment, the regulator 41 and the ink reservoir 3, as well as the pen tip 42 and the sealing head 5, can be connected by an interference fit.

[0033] See Figure 5 , Figure 6 The inner edge of the closed head 5 is provided with a number of positioning grooves 54 for the insertion of the first partition 31. The number of positioning grooves 54 is the same as the number of ink storage chambers 32. When the closed head 5 and the ink storage component 3 are assembled, they can play a positioning role, thereby ensuring the effectiveness of the connection between the regulator 41 and the pen tip 42, so that the ink can flow directly into the pen tip 42 through the regulator 41.

[0034] See Figure 7 The outer end of the closed head 5 is provided with an extension 81, through which the pen tip 42 passes. This increases the effective contact area between the pen tip 42 and the closed head 5, ensuring that the closed head 5 moves the pen tip 42 during writing while also limiting the deformation of the pen tip 42. A limiting part 82 is provided at the center of the extension 81, which can separate the pen tips 42, reducing the risk of the pen tips 42 coming into contact and affecting the writing color, and ensuring the use effect of different writing colors of the highlighter. The limiting part 82 is provided with a receiving groove 83 that is adapted to the pen tip 42, which improves the fit between the pen tip 42 and the closed head 5, and ensures the limiting effect of the closed head 5 on the movement and deformation of the pen tip 42.

[0035] In this embodiment, the side of the extension 81 is provided with a plurality of grooves 84 arranged at equal angles around its central axis. The number of grooves 84 is the same as the number of pen tips 42, which reduces the risk of the pen tip obstructing the field of vision for viewing the writing marks.

[0036] In this embodiment, the pen tip 42 is a wide-tipped pen tip 42. The end face of the outer end of the pen tip 42 is inclined relative to the central axis of the closed head 5. The outer end of the pen tip 42 is provided with four faceted structures 91 and forms a sharp part 92, so that when writing, the pen tip 42 can form writing marks of different thicknesses through the inclined surfaces of different widths and the sharp part 92, which meets the user's needs for different writing marks and improves the flexibility of use.

[0037] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
