[0038] Reference Figure 1 , Figure 2 This utility model provides a paint pen, including a pen tube 100, two pen components 200, and two ink control components 300.

[0039] Reference Figure 1 , Figure 2 In some embodiments, the pen tube 100 is provided with a receiving cavity 110, which contains ink and a stirring element 120. The stirring element 120 is used to stir the ink, reduce ink condensation, ensure uniform ink dispensing, and ensure that the ink always maintains a uniform fluid state. This reduces ink dispensing problems caused by ink condensation at the source, improving the smoothness and quality stability of writing and drawing. Furthermore, two pen components 200 are respectively connected to both ends of the pen tube 100. Each pen component 200 includes a pen tip for writing. The two pen components 200, each containing a pen tip, enable a single paint pen to have two pen tips. The specifications of the pen tips can be set according to actual needs, eliminating the need for users to prepare multiple paint pens with different tip specifications, thereby reducing purchase costs, reducing carrying burden, simplifying the operation process, and improving ease of use.

[0040] Reference Figure 2 , Figure 7In some embodiments, the stirring element 120 is a steel ball. The rolling and impact motion of the steel ball within the pen tube 100's accommodating cavity 110, generated by the pen tube 100's shaking or tilting, thoroughly stirs the ink within the cavity 110, breaking up any clumps or sediment particles formed during the ink's settling process. This results in a more uniform mixing of the ink components, preventing problems such as poor ink flow or uneven concentration caused by localized agglomeration. Simultaneously, the steel ball's high density and hardness generate a stronger impact force during stirring, enhancing the ink's stirring effect and ensuring the ink remains in a uniform fluid state. This provides a uniform ink base for the subsequent functions of the ink control component 300 and the filter 310, further complementing the ink control of the ink control component 300 and the impurity interception of the filter 310 to ensure smooth and uniform ink flow, reducing line breaks and color unevenness, and improving the quality and smoothness of writing and drawing. Of course, in actual design, the structure of the stirring element 120 can be designed according to specific needs.

[0041] In some embodiments, the pen tube 100 is made of aluminum, which is lighter and easier to carry and use compared to other metals. Specifically, the pen tube 100 can be made of aluminum alloy, which has high strength and hardness, making the pen tube 100 more robust and durable, and less prone to deformation or damage. At the same time, aluminum alloy has good corrosion resistance; compared to existing plastic pen tubes 100, the aluminum alloy pen tube 100 can resist the erosion of various chemicals, ensuring that the pen tube 100 maintains its appearance and integrity during long-term use. The aluminum alloy pen tube 100 can undergo surface treatment processes such as polishing and anodizing to present different lusters and textures, resulting in a more aesthetically pleasing appearance that meets modern aesthetic demands.

[0042] Reference Figure 1 In some embodiments, the two pen components 200 are divided into a first pen component 210 and a second pen component 220. The pen tip diameter of the first pen component 210 is larger than that of the second pen component 220, enabling a single paint pen to have two different pen tip sizes, eliminating the need for the user to prepare multiple paint pens with different pen tip sizes. For example, the first pen component 210 with a larger pen tip diameter is suitable for large-area coloring or filling scenes, while the second pen component 220 with a smaller pen tip diameter is suitable for fine line drawing scenes. Of course, in actual design, the pen tip diameters of the first pen component 210 and the second pen component 220 can be designed according to actual needs.

[0043] Reference Figure 2 , Figure 3 , Figure 5In some embodiments, the first pen component 210 includes a thick pen tip 211, a first pen nozzle 212, and a first pen cap 213. The first pen nozzle 212 is fitted over the outside of the thick pen tip 211, with one end of the thick pen tip 211 protruding from the first pen nozzle 212. The other end of the thick pen tip 211 is connected to the ink control component 300, ensuring that the thick pen tip 211 can directly contact the writing surface and, in conjunction with the ink control component 300, stably supply ink, ensuring smooth writing operations when coloring or filling large areas. Furthermore, the first pen nozzle 212 is provided with a first thread, and the pen tube 100 is provided with a second thread. The first thread and the second thread engage to assemble the first pen nozzle 212 and the pen tube 100. This threaded connection method makes the assembly process of the first pen nozzle 212 and the pen tube 100 simple and convenient, ensuring the stability of the connection and preventing loosening or detachment during use, thus improving the overall reliability of the paint pen structure. In addition, the first pen cap 213 is provided with a first protective cavity, and the first pen tip 212 is disposed in the first protective cavity. The end of the first pen cap 213 abuts against the end of the pen tube 100, thereby covering the thick pen tip 211 with the first pen tip 212. This can form a protective barrier when the thick pen tip 211 is not needed for writing, and can isolate the thick pen tip 211 from damage caused by external collisions, friction and other factors, prevent the problem of the pen tip being unusable due to damage, extend the service life of the thick pen tip 211, and ensure the long-term stable use of the paint pen.

[0044] Reference Figure 2 , Figure 4 , Figure 6 In some embodiments, the second pen assembly 220 includes a fine pen tip 221, a second pen nozzle 222, and a second pen cap 223. The second pen nozzle 222 is fitted over the outside of the fine pen tip 221, with one end of the fine pen tip 221 protruding from the second pen nozzle 222. The other end of the fine pen tip 221 is connected to the ink control assembly 300, ensuring that the fine pen tip 221 can directly contact the writing surface and, in conjunction with the ink control assembly 300, stably supply ink, ensuring smooth writing operations when coloring or filling large areas. Furthermore, the second pen nozzle 222 is provided with a third thread, and the pen tube 100 is provided with a fourth thread. The third and fourth threads mate to assemble the second pen nozzle 222 and the pen tube 100. This threaded connection method makes the assembly process of the second pen nozzle 222 and the pen tube 100 simple and convenient, ensuring a stable connection and preventing loosening or detachment during use, thus improving the overall reliability of the paint pen structure. In addition, the second pen cap 223 is provided with a second protective cavity, and the second pen tip 222 is disposed in the second protective cavity. The end of the second pen cap 223 abuts against the end of the pen tube 100, thereby covering the fine pen tip 221 and the second pen tip 222. This can form a protective barrier when the fine pen tip 221 is not writing, and can isolate the fine pen tip 221 from damage caused by external collisions, friction and other factors, prevent the problem of the pen tip being unusable due to damage, extend the service life of the fine pen tip 221, and ensure the long-term stable use of the paint pen.

[0045] In some embodiments, the first tip 212 and the second tip 222 are identical in shape and size, ensuring design versatility and simplifying production molds and assembly processes. Furthermore, since the diameter of the fine tip 221 is smaller than that of the coarse tip 211, a gap exists between the fine tip 221 and the second tip 222. Therefore, a tip sleeve 224 is provided between the fine tip 221 and the second tip 222. The tip sleeve 224 is fitted over the outside of the fine tip 221 and fills the gap between the fine tip 221 and the second tip 222, preventing the fine tip 221 from shaking during writing. This avoids problems such as skewing lines and uneven ink flow caused by tip shaking, thus improving the reliability and writing effect of the paint pen in delicate operation scenarios.

[0046] Reference Figure 4 , Figure 6 In some embodiments, one end of each ink control component 300 is connected to the corresponding pen tip, and the other end of each ink control component 300 is disposed within the receiving cavity 110. A filter element 310 is fitted onto the outer side of each pen tip, and each filter element 310 abuts against the corresponding ink control component 300. The filter element 310 is used to filter ink. Each pen assembly 200 is equipped with a corresponding ink control component 300, which can control the ink flow to the pen tip. The filter element 310 filters the ink, intercepting any impurities or condensed particles that may be present in the ink, preventing them from clogging the pen tip. Furthermore, the ink control component 300 and the filter element 310 cooperate to further ensure smooth and uniform ink flow, reducing line breaks and uneven color caused by ink flow problems, and improving the smoothness of writing and drawing.

[0047] In some embodiments, the filter element 310 is a sponge. Utilizing the sponge's porous structure and excellent adsorption and permeability, it filters the ink flowing from the ink control component 300 to the pen tip, intercepting any small clumps or impurities that may remain in the ink, preventing them from entering the pen tip and causing blockages or affecting ink flow uniformity. Simultaneously, the sponge's soft and elastic texture allows it to fit tightly against the ink control component 300, forming a stable filtration channel without damaging the ink flow structure. Its pores also buffer and guide the ink flow, allowing it to penetrate the pen tip more evenly. Combined with the flow control of the ink control component 300 and the stirring effect of the steel ball, this further improves the smoothness and stability of ink flow, reducing line defects caused by impurities or localized concentration differences during writing, and ensuring writing and drawing quality.

[0048] Reference Figure 3 , Figure 7 , Figure 8In some embodiments, the ink control assembly 300 includes a first housing 320, a second housing 330, and an ink outlet component 340. The second housing 330 is inserted into the first housing 320. The first housing 320 is provided with a first channel 321, and the second housing 330 is provided with a second channel 331. The first channel 321 and the second channel 331 communicate to form an ink outlet channel. At least a portion of the ink outlet component 340 is disposed in the ink outlet channel. The ink outlet component 340 is connected to the pen tip and can move within the ink outlet channel to control the flow of ink into the ink outlet channel. When not writing, the ink outlet component 340 blocks the ink outlet channel to prevent ink from flowing into it, thus avoiding ink leakage, waste, or ink condensation and blockage due to prolonged stagnation, ensuring the stability of ink storage within the pen tube 100. When writing, the pen tip is pressed, which pushes the ink outlet component 340 to move along the side closest to the pen tube 100, allowing the ink outlet component 340 to not block the ink outlet channel. Ink flows into the ink outlet channel and is delivered to the pen tip, meeting the ink supply needs for writing and achieving on-demand ink dispensing. This ensures timely and sufficient ink supply during writing, while the blocking function in non-writing states reduces uneven ink dispensing.

[0049] Reference Figure 4 , Figure 8 In some embodiments, the ink control assembly 300 further includes an elastic element 350, which is sleeved on the outside of the ink outlet element 340. One end of the elastic element 350 abuts against the first housing 320, and the other end of the elastic element 350 abuts against the ink outlet element 340. When writing, the ink outlet element 340 moves along the side closer to the pen tube 100, and the elastic element 350 is compressed to ensure that the ink outlet element 340 moves smoothly to open the ink outlet channel and ensure normal ink supply. When not writing, the elastic element 350 returns to its original position and can provide force to the ink outlet element 340, so that the ink outlet element 340 moves along the side away from the pen tube 100 to the initial sealing position, ensuring that the ink outlet channel is closed and avoiding problems such as poor sealing, ink leakage, or channel blockage caused by poor reset of the ink outlet element 340. In addition, the elastic reset design of the elastic element 350 makes the switching of the ink control assembly 300 more sensitive and stable, eliminating the need for manual reset and improving the ink sealing in non-writing states. At the same time, the buffering effect of the elastic element 350 can reduce the impact when the ink outlet 340 moves, reduce component wear, and extend the service life of the ink control assembly 300.

[0050] In some embodiments, the elastic element 350 can be set as a spring. Of course, in actual design, the structure of the elastic element 350 can be set according to actual needs.

[0051] Reference Figure 4 , Figure 8In some embodiments, the ink outlet component 340 includes a first ink outlet rod 341 and a second ink outlet rod 342 connected to the first ink outlet rod 341. The first ink outlet rod 341 is disposed within a first channel 321 of the first housing 320, and at least a portion of the second ink outlet rod 342 is disposed within a second channel 331 of the second housing 330. The diameter of the first ink outlet rod 341 is smaller than the diameter of the second ink outlet rod 342, such that a first limiting step 343 is formed between the first ink outlet rod 341 and the second ink outlet rod 342. An elastic member 350 is sleeved on the outside of the first ink outlet rod 341. The 50 abuts against the first limiting step 343, thereby limiting the elastic element 350 and ensuring that the elastic element 350 is stably fitted on the outside of the first ink outlet rod 341. This prevents the elastic element 350 from shifting, falling off, or misaligning during compression or reset, ensuring that the elastic element 350 can continuously apply a stable elastic force to the ink outlet element 340. This ensures that when writing, the ink outlet element 340 is pushed by the pen tip to move smoothly to the side of the pen tube 100 to open the ink outlet channel, and when not writing, the elastic element 350 pushes the ink outlet element 340 to reset and block the ink outlet channel, thereby improving the structural stability and ink control reliability of the ink control assembly 300.

[0052] Reference Figure 4 , Figure 9 In some embodiments, an ink-dispensing protrusion 344 is provided on the outer side of the second ink-dispensing rod 342, and a first sealing surface 3411 is provided on the ink-dispensing protrusion 344. A second sealing surface 332 is provided on the inner sidewall of the second channel 331. The first sealing surface 3411 contacts the second sealing surface 332 to prevent ink from flowing into the ink-dispensing channel. When not writing, the tight contact between the first sealing surface 3411 and the second sealing surface 332 forms a reliable sealing structure, blocking the flow of ink into the ink outlet channel and avoiding problems such as ink leakage and ink accumulation in the channel due to poor sealing, thus ensuring the stability of ink storage in the non-writing state. At the same time, the function of the ink outlet protrusion 344 and the elastic element 350 in pushing the ink outlet element 340 to reset works together. When the ink outlet element 340 returns to its initial position, the first sealing surface 3411 and the second sealing surface 332 fit together, improving the reliability of the sealing and reducing uneven ink distribution or contamination caused by sealing failure. In addition, the sealing is achieved by the contact between the first sealing surface 3411 and the second sealing surface 332, eliminating the need for complex sealing components and ensuring the sealing effect without increasing the size and assembly difficulty of the ink outlet assembly.

[0053] Reference Figure 4 , Figure 9In some embodiments, the second ink outlet rod 342 is provided with a mounting groove 3421. The pen tip is divided into a coarse pen tip 211 and a fine pen tip 221. The pen tip includes a base 2111 and an extension 2112 connected to the base 2111. The extension 2112 is disposed in the mounting groove 3421. Through the cooperation between the mounting groove 3421 and the extension 2112, the connection between the pen tip and the ink outlet rod is ensured to be accurate and stable, avoiding pen tip wobbling that affects writing accuracy. In addition, a second limiting step 2113 is formed between the extension 2112 and the base 2111. The second limiting step 2113 abuts against the second ink outlet rod 342, so that the force when the pen tip is pressed can be transmitted to the second ink outlet rod 342. This ensures that the pen tip can stably push the ink outlet rod to open the ink channel during writing, ensuring timely and smooth ink delivery response and improving ink control sensitivity. In addition, the filter element 310 is fitted on the outside of the base 2111, which can filter the ink flowing to the pen tip and enhance the sealing of the connection between the pen tip and the ink outlet rod by fitting with the base 2111, thereby reducing ink leakage.

[0054] Reference Figure 4 , Figure 9 In some embodiments, the second housing 330 includes a head 333 and a tail 334 connected to the head 333. The head 333 is disposed within the first channel 321 of the first housing 320, and the tail 334 abuts against the end of the first housing 320 to form an axial limit. The tail 334 and the first housing 320 work together to prevent ink in the ink outlet channel from flowing out of the ink control assembly 300, ensuring the directional flow of ink in the channel. At the same time, the combination of plug-in and abutment connection makes the assembly of the first housing 320 and the second housing 330 more stable, preventing channel sealing failure due to loosening of the first housing 320 and the second housing 330 during use, and improving the overall structural stability of the ink control assembly 300.

[0055] Reference Figure 4 , Figure 9 In some embodiments, the inner wall of the first channel 321 is provided with a first protruding ring 322, and the outer side of the head 333 is provided with a second protruding ring 335. The first protruding ring 322 and the second protruding ring 335 are engaged, which can form a double limit on the first housing 320 and the second housing 330 in the axial and radial directions, enhance the connection stability after the head 333 is inserted into the first channel 321, and prevent the first housing 320 and the second housing 330 from loosening or separating due to vibration, collision, etc. during use, thus ensuring the integrity of the ink outlet channel structure. At the same time, the engagement of the first protruding ring 322 and the second protruding ring 335 makes the fit between the head 333 and the first channel 321 tighter, and with the abutment of the tail 334 and the end of the first housing 320, it further prevents ink from leaking from the connection part and improves the overall sealing of the ink outlet channel.

[0056] The paint pen of this application includes the following steps during assembly:

[0057] The first step is to assemble the first housing 320, the second housing 330, and the ink outlet component 340 into an ink control assembly 300;

[0058] The second step is to put the filter element 310 on the outside of the coarse pen tip 211, and put the pen tip cover 224 and the filter element 310 on the outside of the fine pen tip 221.

[0059] The third step is to first install one of the ink control components 300 on one end of the pen tube 100, then insert the extension 2112 of the coarse pen tip 211 with the filter 310 on it into the mounting groove 3421 of the ink outlet component 340, then connect the first pen tip 212 to the pen tube 100 and put on the first pen cap 213.

[0060] The fourth step is to place the pen tube 100 with the coarse pen tip 211 installed vertically, with the end of the pen tube 100 without the fine pen tip 221 installed facing upwards, and place the stirring element 120 in the receiving cavity of the tube body, and pour a certain weight of ink into the receiving cavity.
