Description

Technical Field

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

[0002] Highlighters, as a common writing tool, typically consist of a pen barrel, a pen tip at the front of the barrel, and an ink cartridge. The pen tip at the front of the barrel is usually flat and can coat the text to make the text stand out, thus marking the text.

[0003] Existing highlighters can only draw single lines, making the marking method relatively simple. Some users, in addition to highlighting the text with lines, will draw underlines below the text to further emphasize it. This usually requires the use of another pen or a pen that can be reversed (double-ended highlighter), which is cumbersome and can easily lead to uneven gaps between the lines and underlines, making it look unsightly. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a highlighter pen that, while coating text, can also form an underline below the text, providing a better highlighting effect for the text content. Furthermore, the gaps between the drawn lines and the underline are uniform, making it look more aesthetically pleasing.

[0005] This utility model discloses a highlighter pen, comprising a pen barrel, a first pen tip, and an ink storage mechanism. The first pen tip is disposed at one end of the pen barrel, and the ink storage mechanism is disposed inside the pen barrel. The front end of the first pen tip has a flat writing portion. The pen barrel includes a cylindrical portion and a pen tip holder inserted and fixed to one end of the cylindrical portion. The first pen tip and the pen tip holder are fitted and fixed together. A second pen tip is also inserted and fixed to the pen tip holder. The front end of the second pen tip has a thin rod-shaped writing portion. The second pen tip is connected to the ink storage mechanism for ink supply. The writing portion of the second pen tip is disposed adjacent to one side of the writing portion of the first pen tip. The first pen tip and the second pen tip... There is a gap between the front ends, so that the lines drawn by the first and second pen tips are spaced apart and do not overlap. A groove is provided on one side of the writing part of the first pen tip, and the second pen tip is embedded in the groove, making the overall structure of the first and second pen tips more compact. This also allows the first pen tip to provide some support and protection for the second pen tip, preventing it from deforming or being damaged due to excessive writing pressure. The rear ends of both the first and second pen tips have rod-shaped ink supply connection parts for connecting with the ink storage mechanism. The ink storage mechanism is connected to the first and second pen tips through the ink supply connection parts and supplies ink to them.

[0006] The first pen tip can draw thick lines on the paper, and the second pen tip can draw thin lines. When writing, align the first pen tip with the text content and the second pen tip with the blank area below the text. Move the pen along the direction of the text distribution. While marking the text content, it can also form an underline below the text. The two lines are drawn simultaneously, which is convenient to use. The two lines have a uniform gap, which looks more beautiful. This utility model can meet the user's needs for marking text with a thicker tip and also marking it with an underline below the text.

[0007] Furthermore, a limiting part is provided between the writing part and the ink supply connection part of the first and second pen tips, so that a shoulder step is formed between the writing part and the ink supply connection part due to the diameter difference. The pen tip holder is provided with a notch for inserting and fixing the first and second pen tips. The bottom of the notch is provided with two through holes for the ink supply connection parts of the first and second pen tips to pass through to the inside of the barrel, respectively. The limiting part of the first and second pen tips and the inner edge of the through holes form a limiting fit to prevent the first and second pen tips from being pushed into the pen barrel due to writing pressure.

[0008] Furthermore, the inner peripheral wall of the notch has a recess, and the writing part of the second pen tip is embedded in the recess. The inner wall of the recess provides a limiting and supporting function for the second pen tip, preventing the second pen tip from being deformed or damaged by writing pressure.

[0009] Furthermore, a ventilation hole is formed between the side of the recess that mates with the writing part of the first pen tip and the side of the corresponding through hole, which connects the inside and outside of the pen barrel. This helps to balance the air pressure inside and outside the pen barrel and improves the ink output of the pen.

[0010] Furthermore, the writing part of the second pen tip includes a needle tube and an ink guide core inserted and fixed inside the needle tube. Compared with ordinary microfiber pen tips, the needle tube pen tip draws lines with more uniform and fine lines, and has more stable ink output and greater durability.

[0011] Furthermore, the ink storage mechanism includes two fiber ink sacs, each storing ink of a different color. A partition divides one end of the inner side of the cylinder into two cavities. The ink supply connections of the first and second pen tips are respectively disposed in the two cavities. One end of each fiber ink sac is inserted into one of the two cavities and connected to the ink supply connections of the first and second pen tips. The partition isolates the ink supply connections of the first and second pen tips and the open ends of the two fiber ink sacs, preventing ink leakage and fusion from affecting the purity of the final drawn line color. Additionally, the partition provides support and restraint for one end of each fiber ink sac, preventing movement.

[0012] Furthermore, both fiber ink cartridges are positioned offset from the axis of the pen barrel. One end of each fiber ink cartridge is connected to the ink supply connection of the first and second pen tips, respectively. The other end of the pen barrel is equipped with a third pen tip. The third pen tip and one of the fiber ink cartridges form an ink supply connection. By rotating the pen, the third pen tip can also be used independently on the same pen. The third pen tip can adopt a writing part with a tapered tip, or it can adopt a writing part structure such as the first or second pen tip, or it can adopt a writing part structure of other types.

[0013] Furthermore, the two fiber ink cartridges have different lengths. The other end of the longer fiber ink cartridge extends obliquely towards the center of the pen barrel. A support base connects the other ends of the two fiber ink cartridges. The support base includes an abutment portion that connects and engages with the other end of the shorter fiber ink cartridge and a sleeve portion that engages and engages with the other end of the longer fiber ink cartridge. This provides support for the other ends of the two fiber ink cartridges, preventing relative movement. The other end of the longer fiber ink cartridge connects to a third pen tip, allowing the third pen tip to be positioned at the pen's axis. The longer fiber ink cartridge can simultaneously supply ink to the third pen tip and either the first or second pen tip, making the pen's internal structure more compact and improving the support and positioning effect of the fiber ink cartridges.

[0014] Furthermore, the sleeve is a tubular structure, and multiple slits are provided at staggered intervals on the corresponding sides of the sleeve along the length direction, which can improve the deformation effect of the sleeve, especially the elasticity of the sleeve in the axial and radial directions, so that it can fit into the other end of the inclined extended fiber ink sac.

[0015] Furthermore, the support base and the other end of the shorter fiber ink sac form a plug-in positioning fit, the end of the sleeve and the pen barrel form a plug-in positioning fit, and the ink supply connection part of the third pen tip passes through the sleeve and is connected to the other end of the longer fiber ink sac. The structure is compact and can improve the connection effect between the third pen tip, the support base, the pen barrel and the two fiber ink sacs. Attached Figure Description

[0027] Examples of embodiments of this utility model of fluorescent pen, such as... Figure 1-11 As shown, the pen includes a pen barrel, a first pen tip 21, and an ink storage mechanism. The first pen tip 21 is located at one end of the pen barrel, and the ink storage mechanism is located inside the pen barrel. The front end of the first pen tip 21 has a flat writing section 211. The pen barrel includes a cylindrical portion 11 and a pen tip holder 12 that is inserted and fixed to one end of the cylindrical portion 11. The first pen tip 21 and the pen tip holder 12 are inserted and fixed together. A second pen tip 22 is also inserted and fixed to the pen tip holder 12. The front end of the second pen tip 22 has a thin rod-shaped writing section 221. The second pen tip 22 is connected to the ink storage mechanism for ink supply. The writing section of the second pen tip 22 is located adjacent to the writing section of the first pen tip 21 on one side. The writing sections of the two pen tips are aligned, that is, when writing, the frontmost ends of the writing sections of the two pen tips are aligned. Both the first and second pen tips 21 and 22 are able to contact the paper simultaneously. There is a gap between the front ends of the first pen tip 21 and the second pen tip 22, so that the lines drawn by the first and second pen tips are spaced apart and do not overlap. A groove 210 is provided on one side of the writing part of the first pen tip 21, and the second pen tip 22 is embedded in the groove 210, making the overall structure of the first and second pen tips more compact. The first pen tip 21 provides a certain degree of support and protection for the second pen tip 22, preventing it from being deformed or damaged due to excessive writing pressure. The rear ends of the first pen tip 21 and the second pen tip 22 are both rod-shaped ink supply connection parts (212, 222) for connecting with the ink storage mechanism. The ink storage mechanism is connected to the first and second pen tips through the ink supply connection parts and supplies ink to them.

[0028] The first pen tip 21 can draw thick lines on the paper, and the second pen tip 22 can draw thin lines on the paper. When writing, the first pen tip 21 is aligned with the text content, and the second pen tip 22 is aligned with the blank area below the text. The pen is moved along the direction of the text distribution. While marking the text content, an underline is also formed below the text. The two lines are drawn simultaneously, which is convenient to use. The two lines have a uniform gap, which looks more beautiful. This utility model can meet the user's needs for marking text with a coating and also marking it with an underline below the text.

[0029] like Figures 5 to 6 , Figure 10 As shown, the diameter of the writing section (211, 221) of the first pen tip 21 and the second pen tip 22 is larger than that of the ink supply connection section (212, 222), so that a shoulder step is formed between the writing section and the ink supply connection section due to the diameter difference, that is, a limiting section is formed. The pen tip holder 12 is provided with a notch 121 for inserting and fixing the first pen tip 21 and the second pen tip 22. The bottom of the notch 121 is provided with two through holes (122, 123) for the ink supply connection sections (212, 222) of the first pen tip 21 and the second pen tip 22 to pass through into the inner side of the cylinder 11, respectively. The shoulder step (i.e. the limiting section) of the first pen tip 21 and the second pen tip 22 and the inner edge of the through hole form a limiting fit to prevent the first and second pen tips from being pushed into the pen barrel due to writing pressure.

[0030] The inner peripheral wall of the notch 121 has a recess 1211, and the writing part 221 of the second pen tip 22 is embedded in the recess 1211. The inner wall of the recess 1211 provides a limiting and supporting function for the second pen tip 22, preventing the second pen tip 22 from being deformed or damaged by writing pressure.

[0031] A vent 120 is formed between the side of the recess 121 that is inserted into the writing part 211 of the first pen tip 21 and the side of the corresponding through hole 122, which can connect the inside and outside of the pen barrel. This is conducive to the balance of air pressure inside and outside the pen barrel and improves the ink output effect of the pen.

[0032] The first pen tip 21 is made entirely of fiber material. The writing section 221 of the second pen tip 22 includes a needle tube 2211 and an ink guide core 2212 fixed inside the needle tube 2211. The ink guide core 2212 is also made of fiber material. Compared with ordinary fine fiber pen tips, needle tube pen tips produce more uniform and precise lines, have more stable ink flow, and are more durable. The shoulder step of the second pen tip 22 is formed by the diameter difference between the needle tube 2211 and the ink guide core 2212. In other embodiments, the shoulder step can also be directly ground and machined onto the fiber material of the second pen tip 22.

[0033] The ink storage mechanism includes two fiber ink sacs (31, 32) that store ink of different colors respectively. The two fiber ink sacs (31, 32) supply ink to the first pen tip 21 and the second pen tip 22 respectively, allowing for the simultaneous drawing of lines in two colors, thus providing better highlighting of the marked text. One end of the inner side of the cylinder 11 has a partition 111, which divides the inner end of the cylinder 11 into two cavities. The ink supply connection part (21) of the first pen tip 21 and the second pen tip 22... The two fiber ink sacs (31, 32) are respectively disposed in two cavities. One end of each fiber ink sac (31, 32) is inserted into one of the two cavities and connected to the ink supply connection (212, 222) of the first pen tip 21 and the second pen tip 22. The partition 111 isolates the ink supply connection (212, 222) of the first and second pen tips and the open ends of the two fiber ink sacs (31, 32), preventing ink leakage and fusion from affecting the purity of the final drawn line color. In addition, the partition 111 also supports and limits one end of the two fiber ink sacs (31, 32) to prevent them from moving.

[0034] In this embodiment, one end of each of the two fiber ink sacs (31, 32) is connected to the ink supply connection (212, 222) of the first pen tip 21 and the second pen tip 22, respectively. The other end of the pen barrel is provided with a third pen tip 23, which is made of fiber material. The third pen tip 23 and one of the fiber ink sacs 32 form an ink supply connection. By turning the pen, the third pen tip 23 can also be used alone on the same pen. The third pen tip 23 has a writing part 231 with a conical tip and an ink supply connection 232. In other embodiments, the same writing part structure as the first pen tip 21 or the second pen tip 22 can also be used, or other common writing part structures can also be used.

[0035] Two fiber ink cartridges (31, 32) are positioned offset from the axis of the pen barrel. The two fiber ink cartridges (31, 32) have different lengths. The other end of the longer fiber ink cartridge 32 extends at an angle towards the center of the pen barrel, utilizing its own deformation capability. A support base 4 connects the other ends of the two fiber ink cartridges (31, 32). The support base 4 includes an abutment portion 41 that connects and engages with the other end of the shorter fiber ink cartridge 31, and a sleeve portion 42 that engages and engages with the other end of the longer fiber ink cartridge 32. This provides support for the other ends of the two fiber ink cartridges, preventing relative movement. The other end of 32 is connected to the third pen tip 23, allowing the third pen tip 23 to be positioned at the pen's axis. This enables the connected fiber ink cartridge 32 to be positioned offset from the center of the pen barrel, facilitating full utilization of the internal space and making the overall design more compact. It also ensures that the third pen tip 23 can be positioned at the center of the pen barrel, eliminating the need to consider the pen's circumferential orientation during writing. This also results in a more symmetrical and aesthetically pleasing appearance at this end. The longer fiber ink cartridge 32 can simultaneously supply ink to both the third pen tip 23 and the second pen tip 22, making the pen's internal structure more compact and improving the support and positioning of the two fiber ink cartridges. Alternatively, in other embodiments, the third pen tip 23 can be designed to share ink with the first pen tip 21.

[0036] The sleeve portion 42 is a tubular structure. On the corresponding two sides of the sleeve portion 42, multiple slits 421 are staggered and distributed along the length direction, which can improve the deformation effect of the sleeve portion 42, especially improve the elasticity of the sleeve portion in the axial and radial directions, so that it can fit into the other end of the inclined extended fiber ink sac 32. In this embodiment, the slits 421 are V-shaped slits. In other embodiments, slits of other shapes such as U-shaped and square can also be used.

[0037] The support base 4 and the other end of the shorter fiber ink sac 31 form a plug-in positioning fit; the inner side of the pen barrel has a narrow hole section 10, the end of the sleeve part 42 and the narrow hole section 10 of the pen barrel form a plug-in positioning fit, the ink supply connection part 232 of the third pen tip 23 passes through the sleeve part 42 and is connected to the other end of the longer fiber ink sac 32. The structure is compact and can improve the connection effect between the third pen tip 23, the support base 4, the pen barrel and the two fiber ink sacs.

[0038] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
