Description
Technical Field
[0001] The utility model relates to the technical field of pens, and more specifically to an ink control structure for a direct liquid drawing pen. Background Art
[0002] The pen tip of a direct liquid soft-tip drawing pen is made of polymer materials such as plastics and fibers. The direct liquid soft-tip drawing pen tip has elasticity. When writing, the pen tip vibrates due to friction with the paper, thereby bringing out the ink from the internal conduit, and the written lines are very smooth, which is mostly used for painting and sketching purposes. In the existing conventional structure of a direct liquid soft-tip drawing pen, in order to meet the need for quick installation, one end of the ink guiding core is directly inserted into the ink cartridge and fixedly connected to the ink cartridge. Therefore, during use, the vibration of the ink cartridge will constantly rub the ink guiding core, resulting in the ink guiding core being easily damaged and uneven ink guiding, thus causing the inability to write.
[0003] As shown in the attached drawings of the specification Figure 1 the prior art shown includes an ink cartridge 1', a water storage device 2', an ink guiding core 3', and a pen tip main body 4'. The water storage device 2' is installed inside the ink cartridge 1'. A through hole 5' for the ink guiding core 3' to pass through is provided in the water storage device 2'. One end of the ink guiding core 3' abuts against the tail end of the pen tip main body 4', and the other end is connected to the ink cartridge 1'. The water storage device 2' and the ink guiding core 3' are tightly fitted. The structure of the pen core connection part set above will cause the connection part between the ink guiding core and the ink cartridge to be easily damaged, resulting in uneven ink guiding of the ink guiding core. In addition, ink guiding is only achieved through a section of the ink guiding core in contact with the ink, so the ink guiding is less, and ultimately it will lead to unsmooth writing. Therefore, the present application proposes an ink control structure for a direct liquid drawing pen. Content of the Utility Model
[0004] The purpose of the utility model is to provide an ink control structure for a direct liquid drawing pen, which can effectively control the ink pressure in two directions, be more resistant to air pressure and temperature fluctuations, have a more excellent anti-leakage performance, not only have more stable ink output but also can store ink and reflux, can protect the ink guiding core from being damaged by impact, improve the ink guiding amount through all-round penetration from the side and bottom, and make writing smoother.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A direct liquid painting pen ink control structure includes a pen head, an ink cartridge, an ink guiding part, a pen body part and a ball. The ink cartridge, the ink guiding part and the ball are all located inside the pen body part. The ball is arranged inside the ink cartridge. One end of the ink guiding part is connected to the ink cartridge. The ink guiding part includes a water storage device and an ink guiding core. An installation hole which is in clearance fit with the ink guiding core is arranged at the center of the water storage device. The ink guiding core passes through the installation hole. The lower end of the ink guiding core is fixedly connected to the tail end of the pen head. The water storage device is integrally composed of a first water storage pipe, a second water storage pipe and a third water storage pipe. The thin sheets of the first water storage pipe have different sparse thicknesses. The thin sheets of the second water storage pipe are uniformly dense. The thin sheets of the third water storage pipe have the same spacing and different thicknesses. Ink guiding grooves are arranged on both sides of the thin sheets of the third water storage pipe. The space between the ink guiding grooves is communicated with the installation hole. A clamping part is arranged inside the third water storage pipe. A plurality of inner rib positions and ink guiding through grooves are circumferentially and equidistantly arranged inside the clamping part. The ink guiding core is clamped in the inner rib positions. The inner rib positions and the ink guiding through grooves are both communicated with the ink cartridge.
[0007] Adopting the above technical solutions, the utility model has the following advantages:
[0008] For the utility model, the thin sheets with different sparse thicknesses of the first water storage pipe can eliminate and adjust the air pressure at the upper part of the water storage device and the vacuum of the ink cartridge, so that the ink can flow down smoothly. In addition, the thin sheets are thickened and hydrophilized, so that the flowing ink is adsorbed on the surface of the thin sheets to store ink and adjust and control the ink output. The uniformly dense thin sheets of the second water storage pipe realize the bidirectional adjustment of the air pressure entering from the outside between the ink cartridge and the first water storage pipe. The surface of the dense thin sheets is thickened and hydrophilized to adsorb and store ink, balance the internal and external pressures, ensure continuous and stable ink flow and return the excess ink to the ink cartridge. The thin sheets of the third water storage pipe have the same spacing and different thicknesses. The surface of the thin sheets is thickened and hydrophilized to absorb and store ink and buffer the ink flow. The combination of the three thin sheets reduces the ink overflow caused by the shaking impact vibration of the ball, and at the same time adjusts the air pressure inside the ink cartridge. The arrangement of the inner rib positions and the ink guiding through grooves in the utility model enables the tail of the ink guiding core to fully draw the ink in the ink cartridge from the ink guiding through grooves evenly and with a large flow rate. The inner rib positions and the ink guiding through grooves are communicated with the ink cartridge, further enabling the bottom of the ink guiding core to fully absorb ink. Moreover, the inner rib positions and the ink guiding through grooves make the side of the ink guiding core in contact with the inner rib positions have an irregular shape, so that the ink guiding core can be fixed to prevent the ink guiding core from rotating. In addition, one end of the ink guiding core is wrapped inside the inner rib positions, so that the ink guiding core does not directly contact the ink cartridge, which can effectively prevent the ink cartridge and the ball inside the ink cartridge from hitting and damaging the ink guiding core when the ink cartridge is installed, playing a role in protecting the ink guiding core and prolonging the service life of the ink guiding core.
[0009] Further, a plurality of annular grooves are formed between the thin sheets of the third water storage pipe. A plurality of annular protrusions are arranged inside the ink cartridge. The third water storage pipe is clamped inside the ink cartridge and fixedly connected through the annular protrusions and the annular grooves.
[0010] With the above technical solutions, the utility model has the following advantages:

[0012] Furthermore, the ink guiding core is a columnar core body with conical ends at both ends.
[0013] With the above technical solutions, the utility model has the following advantages:
[0014] The columnar core body of the ink guiding core of the utility model with conical ends at both ends enables the ink guiding core to just guide the ink.
[0015] Furthermore, the conical surface at one end of the ink guiding core abuts against the bottom end of the inner rib position.
[0016] With the above technical solutions, the utility model has the following advantages:
[0017] The arrangement that the conical surface at one end of the ink guiding core of the utility model abuts against the bottom end of the inner rib position enables the end of the ink guiding core to be quickly positioned, preventing it from directly contacting the ink pipe and playing a role in protecting the ink guiding core.
[0018] Furthermore, one end of the ink guiding through groove communicates with the mounting hole, and the other end of the ink guiding through groove is higher than the position of the ink guiding core.
[0019] With the above technical solutions, the utility model has the following advantages:
[0020] The ink guiding through groove of the utility model communicates with the mounting hole and is higher than the ink guiding core, so that when the ink enters the ink guiding hole, in addition to being directly absorbed by the ink guiding core, it can directly enter the ink guiding through groove, thereby increasing the amount of ink guiding.
[0021] Furthermore, ink guiding channels I and II are respectively arranged on both sides of the thin sheet of the water storage pipe I and the thin sheet of the water storage pipe II, and the ink guiding channel I communicates with the corresponding ink guiding groove.
[0022] With the above technical solutions, the utility model has the following advantages:
[0023] The arrangement of the ink guiding channels I and II of the utility model enables the ink to be stored in the water storage pipe I and the water storage pipe II, ensuring smooth ink output.
[0024] Further, one end of the water storage pipe I close to the pen head is fixedly provided with a fixing part, a clamping ring part is arranged around the fixing part, a concave part is arranged at the position of the pen head corresponding to the clamping ring part, and one end of the fixing part inserted into the pen head is clamped in the corresponding concave part through the clamping ring part for fixed connection.
[0025] Adopting the above technical solutions, the utility model has the following advantages:
[0026] The setting of the clamping ring part and the concave part of the utility model enables the water storage device to be quickly installed and fixed with the pen head, and the ink guiding core is connected with the pen tip of the pen head, so that the ink can be drained to the pen tip to realize writing.

Detailed Description of the Invention
[0033] As Figures 2 to 4As shown, in a specific embodiment of the present invention, a direct liquid painting pen ink control structure includes a pen head 2, an ink cartridge 7, an ink guiding part, a pen body part 1, and a ball. The ink cartridge 7, the ink guiding part, and the ball are all located inside the pen body part 1. The ball is arranged inside the ink cartridge 7. One end of the ink guiding part is connected to the ink cartridge 7. The ink guiding part includes a water storage device and an ink guiding core 13. An installation hole 11 that is in clearance fit with the ink guiding core 13 is provided in the center of the water storage device. The ink guiding core 13 passes through the installation hole 11. The lower end of the ink guiding core 13 is fixedly connected to the tail end of the pen head 2. The water storage device is integrally composed of a first water storage pipe 10, a second water storage pipe 9, and a third water storage pipe 5. The thicknesses of the thin sheets of the first water storage pipe 10 are different and sparse. The thin sheets of the second water storage pipe 9 are evenly dense. The distances between the thin sheets of the third water storage pipe 5 are the same, but the thicknesses are different. Ink guiding grooves 502 are provided on both sides of the thin sheets of the third water storage pipe 5. The space between the ink guiding grooves 502 communicates with the installation hole 11. A clamping part 6 is provided inside the third water storage pipe 5. A plurality of inner rib positions 601 and ink guiding grooves 602 are circumferentially and equidistantly arranged inside the clamping part 6. The ink guiding core 13 is clamped in the inner rib positions 601. Both the inner rib positions 601 and the ink guiding grooves 602 communicate with the ink cartridge 7.
[0034] Through the above settings, the thin sheets with different sparse thicknesses of the first water storage pipe 10 of the present invention can eliminate and adjust the air pressure at the upper part of the water storage device and the vacuum of the ink cartridge 7, enabling the ink to flow smoothly. Additionally, the thin sheets are thickened and hydrophilized to allow the flowing ink to adsorb on the surface of the thin sheets for storing ink and adjusting and controlling the ink output. The evenly dense thin sheets of the second water storage pipe 9 achieve two-way adjustment of the air pressure entering from the outside between the ink cartridge 7 and the first water storage pipe 10. The surface of the dense thin sheets is thickened and hydrophilized to adsorb and store ink, balancing the internal and external pressures to ensure continuous and stable ink flow and returning the excess ink to the ink cartridge 7. The thin sheets of the third water storage pipe 5 with the same distance but different thicknesses have their surfaces thickened and hydrophilized to absorb and store ink and buffer the ink flow. The combination of the three thin sheets reduces the ink overflow caused by the shaking impact and vibration of the ball, while adjusting the air pressure inside the ink cartridge 7. The settings of the inner rib positions 601 and the ink guiding grooves 602 of the present invention enable the tail of the ink guiding core 13 to fully and uniformly draw a large amount of ink from the ink cartridge 7 through the ink guiding grooves 602. The inner rib positions 601 and the ink guiding grooves 602 communicate with the ink cartridge 7, further enabling the bottom of the ink guiding core 13 to fully absorb ink. Moreover, the inner rib positions 601 and the ink guiding grooves 602 make the side of the ink guiding core 13 in contact with the inner rib positions 601 have an irregular shape, thus fixing the ink guiding core 13 to prevent it from rotating. In addition, one end of the ink guiding core 13 is wrapped inside the inner rib positions 601, so that the ink guiding core 13 does not directly contact the ink cartridge 7, effectively preventing the ink cartridge 7 and the ball inside the ink cartridge 7 from hitting and damaging the ink guiding core 13 during the installation of the ink cartridge 7, playing a role in protecting the ink guiding core 13 and extending the service life of the ink guiding core 13.
[0035] As Figures 3 to 4As shown, a number of annular grooves 501 are formed between the thin sheets of the third water storage pipe 5. A number of annular protrusions 701 are provided inside the ink cartridge 7. The third water storage pipe 5 is clamped inside the ink cartridge 7 and fixedly connected through the clamping of the annular protrusions 701 and the annular grooves 501. The ink guiding core 13 is a columnar core body with conical ends at both ends. The conical surface at one end of the ink guiding core 13 abuts against the bottom end of the inner rib position 601. One end of the ink guiding groove 602 communicates with the mounting hole 11, and the other end of the ink guiding groove 602 is higher than the position of the ink guiding core 13. Ink guiding channels 8 and 12 are respectively provided on both sides of the thin sheets of the first water storage pipe 10 and the second water storage pipe 9. The ink guiding channel 8 communicates with the corresponding ink guiding groove 502. One end of the first water storage pipe 10 close to the pen tip 2 is fixedly provided with a fixing part 4. A clamping ring part 401 is provided around the fixing part 4. An inner concave part 201 is provided at the position of the pen tip 2 corresponding to the clamping ring part 401. The fixing part 4 is inserted into one end of the pen tip 2 and is clamped in the corresponding inner concave part 201 through the clamping ring part 401 for fixed connection.
[0036] Through the above settings, the arrangement of the annular grooves 501 on the third water storage pipe 5 and the annular protrusions 701 inside the ink cartridge 7 of the present utility model enables the third water storage pipe 5 to be quickly connected and fixed to the ink cartridge 7, making the connection between the ink cartridge 7 and the ink guiding part more convenient. The columnar core body of the ink guiding core 13 with conical ends at both ends of the present utility model enables the ink guiding core 13 to just guide the ink. The arrangement that the conical surface at one end of the ink guiding core 13 of the present utility model abuts against the bottom end of the inner rib position 601 enables the end of the ink guiding core 13 to be quickly positioned, preventing it from directly contacting the ink pipe and playing a role in protecting the ink guiding core 13. The ink guiding groove 602 of the present utility model communicates with the mounting hole 11 and is higher than the ink guiding core 13. When ink enters the ink guiding hole 602, in addition to being directly absorbed by the ink guiding core 13, it can directly enter the ink guiding groove 602, thereby increasing the amount of ink guiding. The arrangement of the ink guiding channels 8 and 12 of the present utility model enables ink to be stored in the first water storage pipe 10 and the second water storage pipe 9, ensuring smooth ink output. The arrangement of the clamping ring part 401 and the inner concave part 201 of the present utility model enables the water storage device to be quickly installed and fixed to the pen tip 2, and the ink guiding core 13 is connected to the pen tip 3 of the pen tip 2, so that ink can be drained to the pen tip 3 for writing.
[0037] Working principle: During installation, simply insert the ink guiding core 13 into the installation hole 11 of the water storage device until the ink guiding core 13 abuts against the inner rib position 601. Then, align the fixing part 4 with the pen head part 2 and insert it, so that the snap ring part 401 is clamped and fixed with the concave part 201. At this time, one end of the ink guiding core 13 is in contact and connected with the pen tip 3. Then, place it into the pen body part 1, align the ink cartridge 7 with the water storage pipe three 5 of the water storage device and insert it, so that the annular protrusion 701 and the annular groove 501 are clamped and fixed with each other, and the water storage device can be fixed with the ink cartridge 7. Then, install the remaining components of the pen body part 1 and the components of the pen head part 2. The installation is fast and convenient, and can effectively protect the ink guiding core 13 to prevent the ink guiding core 13 from being damaged; During use, the ink will enter the first ink guiding channel 8 through the ink guiding groove 502, and then pass through the second ink guiding channel 12, so that the ink can be stored in the water storage device and continuously supply ink to the ink guiding core 13. The ink can also pass through the ink guiding groove 502 and the ink guiding through groove 602 to contact the ink guiding core 13, so that the ink guiding core 13 can guide the ink to the pen tip 3, increasing the amount of ink guiding and making the writing of the pen tip 3 smoother; The specific structures of the pen body part 1 and the pen head part 2 of the present utility model and the method of their installation are all disclosed in the prior art, so they will not be elaborated too much here.
[0038] The above is only the preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
