Description

Technical Field

[0001] This invention relates to the field of fountain pen technology, and specifically to a fountain pen with a pure gold nib. Background Technology

[0002] Gold-plated stationery (such as fountain pens) refers to stationery made primarily of gold. It possesses a beautiful, bright yellow luster and exhibits excellent chemical stability, resisting discoloration upon heating. Combining decorative and investment value, it is highly sought after. With economic development and rising consumer awareness, the demand for gold-plated stationery is increasingly strong.

[0003] Gold jewelry can be categorized into pure gold and karat gold based on its gold content. Pure gold jewelry requires a gold content of 99% or higher, with a maximum of 99.99%, and is also known as "nine-nine gold," "pure gold," or "red gold." According to national standards, 24K gold should contain 100% gold, but since no gold is truly pure, 24K gold actually contains over 99.99% gold, also called "thousand-foot gold." Pure gold is relatively soft and easily deformed, and it wears down easily. It is difficult to meet the hardness requirements of fountain pen nibs. Usually, other metallic elements are added to pure gold to adjust its physical properties, such as increasing hardness. However, currently available gold fountain pen nibs are commonly 10K or 14K gold; pure gold nibs with a gold content of over 99% are still unseen. Therefore, the lack of pure gold nibs is undoubtedly a regrettable situation. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fountain pen with a pure gold nib, thus solving the problem of existing fountain pens lacking a pure gold nib.

[0005] The technical solution to achieve the above objectives is: This invention provides a fountain pen with a pure gold nib, comprising: The pen feed has a mounting groove at the top, the mounting groove is oriented in the same direction as the pen feed, the mounting groove is connected to the front end of the pen feed, and the groove wall of the mounting groove is provided with an ink guide groove. A pure gold pen tip is fitted onto the pen feed. The pure gold pen tip has a corresponding protrusion formed on the mounting groove. The protrusion is embedded in the mounting groove, and a portion of the protrusion extends out of the mounting groove and connects with the tip of the pure gold pen tip. The bottom surface of the portion of the protrusion extending out of the mounting groove is provided with an ink guide slit, which connects the tip of the pure gold pen tip with the ink guide groove in the mounting groove.

[0006] A further improvement of the present invention for a fountain pen with a pure gold nib is that an ink-guiding paper is laid in the mounting groove, the fiber extension direction of the ink-guiding paper is consistent with the setting direction of the mounting groove, and the ink-guiding paper is disposed between the protrusion of the feed and the pure gold nib.

[0007] A further improvement of the present invention for a fountain pen with a pure gold nib is that the mounting groove has a bottom wall and two side walls connected to the bottom wall, the two side walls are arranged at an inclination, and the width of the top opening of the mounting groove is greater than the width of the bottom wall.

[0008] A further improvement of the present invention for a fountain pen with a pure gold nib is that the ink guide grooves are multiple and distributed on the bottom wall and side wall of the grooves.

[0009] A further improvement of the present invention for a fountain pen with a pure gold nib is that the wall of the mounting groove is further provided with a receiving groove, and a heating wire is embedded in the receiving groove, the heating wire being electrically connected to a power supply battery.

[0010] A further improvement of the present invention for a fountain pen with a pure gold nib is that the pure gold nib further includes plate-shaped portions located on both sides of the protrusion, the ends of which are bent downward to cover the corresponding sides of the feed.

[0011] A further improvement of the present invention for a fountain pen with a pure gold nib is that the tip of the pure gold nib is spherical.

[0012] A further improvement of the present invention for a fountain pen with a pure gold nib is that the ink guide slits are multiple, and the multiple ink guide slits are connected to the tip of the pure gold nib.

[0013] A further improvement of the present invention for a fountain pen with a pure gold nib is that the depth of the ink guide slit is 1 / 10 to 1 / 2 of the thickness of the protrusion.

[0014] A further improvement of the present invention regarding the pen with a pure gold nib is that the pure gold nib is made of an alloy material containing at least 99% gold, 0.00118%~0.7% titanium, 0.00216%~0.5% chromium, and 0.00324%~0.8% iridium by weight.

[0015] The beneficial effects of the fountain pen with a pure gold nib of the present invention are as follows: This invention relates to a fountain pen with a pure gold nib. The nib is supported by the feed, improving its structural stability. Furthermore, the nib has a raised section that increases its thickness, thereby enhancing its strength and preventing deformation. Additionally, this invention modifies the ink delivery path, placing the ink channel on the feed and the ink guide slit on the bottom of the raised section, instead of creating a through-slit on the upper surface of the nib. This improves the overall integrity of the nib. The ink channel and slit design ensure smooth ink delivery to the nib tip, guaranteeing smooth writing and preventing tip deformation, thus enhancing the nib's structural stability.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] See Figure 1 This invention provides a fountain pen with a pure gold nib, the gold content of which is over 99%, solving the problem of the lack of pure gold nibs in existing technologies and meeting people's demand for gold stationery. This invention improves the strength of the pure gold nib through its structural design, ensuring smooth writing. It also modifies the ink guide path to avoid gaps on the upper surface of the nib, improving the overall integrity of the nib structure and reducing nib deformation. The structure of the fountain pen with a pure gold nib according to this invention will be described below with reference to the accompanying drawings.

[0026] See Figure 1 This image shows a side view of the pen with a pure gold nib according to the present invention. (See also...) Figure 3 , showed Figure 2 Sectional view AA in the diagram. See also... Figure 4 This diagram shows an exploded view of the feed and nib of the fountain pen with a pure gold nib according to the present invention. The following is in conjunction with... Figure 1 , Figure 3 and Figure 4The present invention will describe a fountain pen with a pure gold nib.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the fountain pen with a pure gold nib of the present invention includes a feed 21 and a pure gold nib 22. The top of the feed 21 is provided with an inlay groove 211, the inlay groove 211 being oriented in the same direction as the feed 21. The inlay groove 211 communicates with the front end of the feed 21, and an ink guide groove 212 is provided on the groove wall of the inlay groove 211. The pure gold nib 22 is fitted onto the feed 21, and a corresponding protrusion 221 is formed on the pure gold nib 22 corresponding to the inlay groove 211. The protrusion 221 is embedded in the inlay groove 211. Figure 7 As shown, a portion of the protrusion 221 extends out of the mounting groove 211 and connects with the tip 223 of the pure gold pen tip 22. The bottom surface of the portion of the protrusion 221 extending out of the mounting groove 211 is provided with an ink guide slit 224, which connects the tip 223 of the pure gold pen tip 22 with the ink guide groove 212 in the mounting groove 211.

[0028] The gold-plated pen nib 22 of this invention features a protrusion 221 on its back side. This protrusion 221 is strip-shaped and extends along the length of the gold-plated pen nib 22. The protrusion 221 increases the structural thickness of the gold-plated pen nib 22, thereby increasing its structural strength and making it less prone to deformation. The ink guide path is positioned between the gold-plated pen nib 22 and the feed 21, avoiding gaps on the upper surface of the gold-plated pen nib 22. This allows the tip 223 of the gold-plated pen nib 22 to be a single, integral structure, avoiding the problem of existing pen nibs having two separate parts that easily separate during writing. It also prevents the tip 223 of the gold-plated pen nib 22 from deforming during writing. Most of the gold-plated pen nib 22 is located on the feed 21, which supports the gold-plated pen nib 22, improving its structural stability and preventing deformation.

[0029] Furthermore, the ink guide slit 224 does not penetrate the upper surface of the pure gold pen nib 22; therefore, in combination with... Figure 6 As shown, the present invention ensures the integrity and completeness of the upper surface of the pure gold pen tip 22, thereby improving the overall structural strength of the pure gold pen tip 22 and reducing deformation.

[0030] In one specific embodiment of the present invention, such as Figure 3 As shown, ink-guiding paper is laid in the mounting groove 211. The fiber extension direction of the ink-guiding paper is consistent with the setting direction of the mounting groove 211. The ink-guiding paper is located between the protrusion 221 of the feed 21 and the gold nib 22. By setting the ink-guiding paper, the flow of ink is increased to ensure the amount of ink output and writing effect at the tip 223 of the gold nib 21.

[0031] Ink-guiding paper is a paper material with good toughness and fibers, such as filter paper and facial tissue.

[0032] Furthermore, the ink guide paper is placed inside the ink guide groove 212. Preferably, the ink guide paper is fully filled in the ink guide groove 212. The ink guide paper can absorb ink and guide the ink to the tip 223 of the gold pen tip 21, thereby avoiding ink overflow in the ink guide groove 212.

[0033] In one specific embodiment of the present invention, such as Figure 3 As shown, the mounting groove 211 has a bottom wall and two side walls connected to the bottom wall. The two side walls are inclined. The width of the top opening of the mounting groove 211 is greater than the width of the bottom wall.

[0034] The shape of the protrusion 221 on the pure gold pen tip 22 matches the shape of the mounting groove 211.

[0035] Furthermore, multiple ink guide grooves 212 are provided, distributed on the bottom wall and side wall of the groove.

[0036] Combination Figure 4 and Figure 5 As shown, the mounting groove 211 is provided on the top surface of the pen feed 21. The mounting groove 211 is recessed downward from the top surface of the pen feed 21, combined with... Figure 2 As shown, one end of the mounting groove 211 is located near the rear end of the feed 21, with a certain distance between it and the rear end of the feed 21. This distance is used to accommodate the installation of the feed 21, meaning that part of the rear end of the feed 21 is mounted on the pen body 11. The other end of the mounting groove 211 communicates with the front end of the feed 21, meaning that the mounting groove 211 forms an opening at the front end of the feed 21, from which the protrusion 221 of the pure gold pen tip 22 extends.

[0037] Combination Figure 7 and Figure 8 As shown, the rear end of the pure gold pen tip 22 also forms a plug-in part for plugging and mounting on the pen body 11. The protrusion 221 formed on the pure gold pen tip 22 is inserted into the mounting groove 211 of the nib 21. The front end of the protrusion 221 forms an extension 222 that connects to the tip 223. The extension 222 extends out from the front end of the mounting groove 211. The ink guide slit 224 is provided on the extension 222. The ink guide slit 224 also extends towards the rear end of the protrusion 221 to improve the ink guiding effect.

[0038] The protrusion 222 has a variable cross-section structure, and the thickness of the protrusion 222 becomes thinner towards the tip 223. The bottom surface of the protrusion 222 is an inclined surface to avoid affecting normal writing.

[0039] Furthermore, there are multiple ink guide slits 224, and the multiple ink guide slits 224 are connected to the end of the tip 223 of the pure gold pen tip 22, so as to centrally supply ink to the tip 223.

[0040] Furthermore, the depth of the ink guide slit 224 is 1 / 10 to 1 / 2 of the thickness of the protrusion 221. This ink guide slit 224 does not penetrate the pure gold pen tip 22, thereby improving the integrity and structural strength of the pure gold pen tip 22 and preventing deformation of the pure gold pen tip.

[0041] Furthermore, such as Figure 8 As shown, the tip 223 of the pure gold nib 22 is spherical. The part of the tip 223 that contacts the writing surface has an arc-shaped structure, which makes the contact with the writing surface smoother and improves the writing effect.

[0042] In one specific embodiment of the present invention, such as Figure 3 As shown, the groove wall of the mounting groove 211 is also provided with a receiving groove 214, and a heating wire 23 is embedded in the receiving groove 214. The heating wire 23 is electrically connected to a power supply battery.

[0043] The power supply battery can supply power to the heating wire 23 so that the heating wire 23 is positioned close to the gold pen tip 22. The high gold content of the gold pen tip 22 makes it easy to heat and conduct heat, thereby heating the ink between the mounting groove 211 and the gold pen tip 22 to improve the ink's fluidity. This ensures that the ink can have good fluidity even when the external temperature is low, thus guaranteeing writing quality.

[0044] The power supply battery is connected to the heating wire 23 via a wire, and a switch is also connected to the wire. The switch is located on the outside of the pen body so that the user can easily reach it to turn the heating function on and off. The power supply battery can be hidden inside the feed 21, that is, the mounting groove 211 of the feed 21 provides installation space for the power supply battery, preventing it from being exposed and affecting the aesthetics of the pen. In addition, when the power supply battery is depleted, it can be replaced by pulling out the gold nib 22.

[0045] In one specific embodiment of the present invention, such as Figure 3 , Figure 6 and Figure 7 As shown, the pure gold pen tip 22 also includes plate-shaped portions located on both sides of the protrusion 221, the ends of which are bent downward to cover the corresponding sides of the feed 22.

[0046] like Figure 2 and Figure 4As shown, the inside of the feed 22 is provided with an ink guiding channel 213. One end of the ink guiding channel 213 is connected to the bottom wall of the mounting groove 211, and the other end of the ink guiding channel 213 is located on the rear end face of the feed 22. The rear end of the feed 22 is inserted into the front side of the pen body 11. An ink guiding tube 12 is provided inside the pen body 11. One end of the ink guiding tube 12 is inserted into the ink guiding channel 213, and the other end of the ink guiding tube 12 extends into the ink sac on the pen body 11. The ink guiding tube 12 can guide the ink in the ink sac into the ink guiding channel 213. The ink guiding channel 213 then guides the ink into the mounting groove 211. The ink then flows towards the tip 223 through the ink guiding groove 212 and the ink guiding paper in the mounting groove 211, and then flows into the tip 223 through the ink guiding slit 224 provided on the bottom surface of the protrusion 221 to achieve writing.

[0047] In one specific embodiment of the present invention, a hydrophilic coating is applied to the writing portion of the tip 213. The hydrophilic coating is preferably applied to the lower surface of the tip 213. By applying the hydrophilic coating, the spreading and flow properties of ink on the tip surface can be improved, thereby enhancing writing smoothness.

[0048] The hydrophilic coating can be made of polymer materials, such as polyethylene glycol and polyvinyl alcohol, which all have good hydrophilic properties.

[0049] Specifically, the raw material for the hydrophilic coating can be heated and melted, and then the tip of the pure gold pen tip can be immersed in the molten hydrophilic coating, thereby coating the tip with the hydrophilic coating. After cooling, the hydrophilic coating can be polished to reduce its thickness and make the surface of the hydrophilic coating smooth.

[0050] In one specific embodiment of the present invention, the pure gold pen tip 22 is made of an alloy material containing at least 99% gold, 0.00118%~0.7% titanium, 0.00216%~0.5% chromium and 0.00324%~0.8% iridium by weight.

[0051] Furthermore, the tip 223 of the pure gold pen tip 22 is welded to the front end of the protrusion 221, and the pure gold pen tip 22 can be welded using high-precision welding processes such as laser welding.

[0052] Furthermore, the alloy material of the tip 223 includes 99% gold, 0.1% chromium and 0.9% iridium by weight.

[0053] The alloy material of the pure gold pen nib 22, excluding the tip 223, includes 99.99% gold, 0.00232% titanium, 0.00281% chromium and 0.00487% iridium by weight.

[0054] The 22 Pure Gold Nib is made of 99.99% gold except for the tip. The tip itself is made of 99% gold, and the overall gold content is high, meeting the requirements for pure gold and satisfying the gold content requirements of high-end pen nibs.

[0055] In the production of a pure gold pen nib, the aforementioned alloy raw materials are mixed and melted according to a set weight ratio, poured into a mold for shaping, and then further cooled in cold water. After cooling, the cast gold structure is annealed at least twice, heated to approximately 500°C, to eliminate internal stress generated during casting. After annealing, the gold structure is rolled to form the desired shape, and then the spherical tip is welded to the front end of the pure gold pen nib 22. Ink guide slits are then cut on the protrusion of the pure gold pen nib, and the spherical tip is polished, thus completing the production of the pure gold pen nib.

[0056] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
