Description

Technical Field

[0001] This application relates to the field of liquid eyeliner technology, specifically a highly sealing liquid eyeliner. Background Technology

[0002] Liquid eyeliner is a makeup product used to enhance and accentuate the eye makeup, making the eyes appear larger and more expressive. It boasts advantages such as long-lasting wear, smudge-proof formula, smooth and fluid application, and precise and adherent application, making it increasingly popular.

[0003] An existing patent (publication number: CN215958723U) discloses a retractable liquid eyeliner pen, including: a pen core and a pen barrel. The pen core includes a pen barrel and a pen tip disposed on the pen barrel. The pen barrel has a pen cavity, and the pen barrel is slidably disposed in the pen cavity. A damping mechanism is provided between the pen barrel and the pen cavity. The damping mechanism can position the relative position of the pen barrel and the pen barrel. By sliding and adjusting the position between the pen barrel and the pen barrel, the length of the liquid eyeliner pen can be increased or decreased, making it convenient for users to operate or store. Furthermore, the damping mechanism makes it easier to position the pen barrel and the pen barrel, making it more convenient to use.

[0004] However, in actual use, since the liquid eyeliner needs air to flow out, the inside of the pen needs to have a gap for air circulation. But with a gap, the liquid eyeliner is prone to leaking out, causing leakage and making it inconvenient to use. In order to solve the above problems, a high-sealing liquid eyeliner pen has been proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a highly airtight liquid eyeliner pen that not only resolves the conflict between air pressure balance and leak prevention, but also improves ease of use and hygiene.

[0006] To achieve the above objectives, this application provides the following technical solution: a high-sealing liquid eyeliner pen, comprising a pen barrel, a pen tip, and a pen cap. The pen tip has multiple micro-vent holes at its top. The inner wall of the pen tip is coated with a hydrophobic coating adapted to the micro-vent holes. A first sealing ring is fixedly connected to the inner wall of the pen tip. A connecting tube is fixedly connected to the inner wall of the first sealing ring. A high-density fiber pen tip is installed at one end of the connecting tube, and a first one-way valve is installed at the other end of the connecting tube. A liquid reservoir is installed inside the pen barrel. An outlet pipe and an air inlet pipe are respectively connected to both ends of the liquid reservoir. A second one-way valve is installed on a section of the outlet pipe, and a third one-way valve is installed on a section of the air inlet pipe. A water-guiding core is provided inside the pen barrel. Both ends of the water-guiding core are respectively fitted inside the connecting tube and the outlet pipe. A silicone sealing cylinder is fixedly connected to one end of the pen cap, and a second sealing ring is fixedly connected to the inner wall of the pen cap.

[0007] The above solution utilizes micro-vents and a hydrophobic coating to reduce eyeliner leakage while maintaining balanced air pressure. The first sealing ring further reduces the likelihood of leakage between the pen tip and the connecting tube. The first and second one-way valves work together to restrict the flow of fluid, preventing external air from entering the reservoir through the connecting tube and outlet tube. Gas entering the pen through the micro-vents is redirected to the reservoir via the inlet tube and the third one-way valve, thus achieving pressure balance and ensuring proper eyeliner delivery. When not in use, the pen cap is mounted on top of the pen, and a relatively sealed space is formed between the pen and cap via a silicone sealing tube. This seals the micro-vents, preventing pressure imbalance within the reservoir and thus preventing eyeliner leakage through the inlet wick.

[0008] Furthermore, the pen tip is fixedly connected to the top of the pen barrel, the pen cap is installed on the top of the pen barrel, and the pen tip is located between the pen barrel and the pen cap.

[0009] The above scheme defines the relationship between the pen barrel, pen tip, and pen cap, making the distribution of the structure in the device more reasonable.

[0010] Furthermore, one end of the water-guiding core is connected to the high-density fiber pen tip, and the other end of the water-guiding core is inserted into the interior of the liquid storage cylinder.

[0011] The above scheme defines the position of the water-guiding core, which allows the eyeliner liquid inside the reservoir to be delivered to the high-density fiber pen tip for use.

[0012] Furthermore, a filter screen is fixedly connected to the air intake end of the air intake pipe.

[0013] The above-mentioned solution effectively prevents dust from entering the liquid storage tank through the air inlet pipe, thus optimizing the actual usage effect.

[0014] Furthermore, the outer surface of the pen barrel is provided with a threaded groove, and the inner wall of the pen cap is provided with a threaded protrusion that matches the threaded groove. The pen barrel and the pen cap are connected by a threaded groove and a threaded protrusion.

[0015] The above solution allows the pen cap to be easily installed on the top of the pen barrel, and ensures that the cap will not easily fall off after being tightened.

[0016] Furthermore, the inner wall of the pen barrel is fixedly connected to multiple connecting blocks, and the other end of each of the multiple connecting blocks is fixedly connected to the outer surface of the liquid storage cylinder.

[0017] The above solution allows the multiple connecting blocks to stably install the liquid reservoir inside the pen barrel, facilitating a stable supply of eyeliner liquid.

[0018] Furthermore, the high-density fiber pen tip is located inside the silicone sealing cylinder, and the other end of the silicone sealing cylinder is in contact with the micro-vent holes opened on the surface of the pen tip.

[0019] With the above solution, when the pen cap is tightened, the silicone sealing tube can make close contact with the high-density fiber pen tip, preventing the eyeliner from drying out and thus extending its service life. In addition, the silicone sealing tube can seal the micro-vent holes, thereby improving the leak-proof effect.

[0020] Furthermore, the outer surface of the pen barrel is inlaid with an anti-slip sleeve, and the outer surface of the anti-slip sleeve is provided with evenly distributed anti-slip textures.

[0021] The above solution provides an anti-slip grip design, improving user comfort.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This highly sealed liquid eyeliner pen, through its micro-vents and hydrophobic coating, reduces leakage while maintaining balanced air pressure. A first sealing ring further minimizes leakage between the pen tip and the connecting tube. A first and second one-way valve work together to restrict fluid flow, preventing external air from entering the reservoir through the connecting tube and outlet tube. Gas entering the pen through the micro-vents is redirected to the reservoir via the inlet tube and third one-way valve, thus balancing air pressure and ensuring proper liquid eyeliner delivery. When not in use, the cap is mounted on the top of the pen, and a silicone sealing tube creates a relatively sealed space between the pen and cap, blocking the micro-vents and preventing pressure imbalance within the reservoir. This prevents liquid eyeliner from flowing out through the inlet core, thus preventing leakage. Attached Figure Description

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 3 and Figure 5 This embodiment of a high-sealing liquid eyeliner pen includes a pen barrel 1, a pen tip 2, and a pen cap 3. The pen tip 2 is fixedly connected to the top of the pen barrel 1, and the pen cap 3 is installed on the top of the pen barrel 1. The pen tip 2 is located between the pen barrel 1 and the pen cap 3, which defines the relationship between the pen barrel 1, the pen tip 2, and the pen cap 3, making the distribution of the structure in the device more reasonable. The top of the pen tip 2 has multiple micro-vent holes 4. The inner wall of the pen tip 2 is coated with a hydrophobic coating 5 that is compatible with the micro-vent holes 4. Through the interaction of the micro-vent holes 4 and the hydrophobic coating 5, the pressure can be balanced, and the liquid eyeliner can be prevented from seeping in. The inner wall of the pen tip 2 is fixedly connected to a first sealing ring 6. The inner wall of the first sealing ring 6 is fixedly connected to a connecting tube 7. A high-density fiber pen tip 8 is installed at one end of the connecting tube 7, and a first one-way valve 9 is installed at the other end of the connecting tube 7. The first one-way valve 9 can limit the direction of fluid flow inside the connecting tube 7, preventing external air from being delivered to the inside of the pen barrel 1 through the connecting tube 7.

[0034] Please see Figure 4 , Figure 5 and Figure 6The pen barrel 1 houses a liquid reservoir 11. Multiple connecting blocks 17 are fixedly connected to the inner wall of the pen barrel 1, with the other ends of each connecting block 17 fixedly connected to the outer surface of the liquid reservoir 11. These connecting blocks 17 allow the liquid reservoir 11 to be stably installed inside the pen barrel 1, facilitating a stable supply of eyeliner liquid. The two ends of the liquid reservoir 11 are connected to an outlet pipe 12 and an air inlet pipe 14, respectively. A second one-way valve 13 is installed on the outlet pipe 12. One end of the water guide 10 is connected to the high-density fiber pen tip 8, and the other end of the water guide 10 is inserted into the interior of the liquid reservoir 11, defining the position of the water guide 10. The water guide 10 allows the eyeliner liquid inside the liquid reservoir 11 to be transported to the high-density fiber pen tip. In the case of use 8, a third one-way valve 15 is installed on the section of the air inlet pipe 14, and a filter screen 16 is fixedly connected to the air inlet end of the air inlet pipe 14. The filter screen 16 can effectively prevent dust from entering the liquid storage cylinder 11 through the air inlet pipe 14, thus optimizing the actual use effect. The pen barrel 1 is equipped with a water guide 10 inside, and the two ends of the water guide 10 are respectively sleeved inside the connecting pipe 7 and the liquid outlet pipe 12. The first one-way valve 9, the second one-way valve 13 and the third one-way valve 15 can optimize the balance of air pressure inside the liquid storage cylinder 11. In general, the gas will enter the interior of the liquid storage cylinder 11 through the air inlet pipe 14, and the eyeliner liquid inside the liquid storage cylinder 11 will be transported through the connecting pipe 7, the water guide 10 and the liquid outlet pipe 12.

[0035] Please see Figure 2 , Figure 4 and Figure 5 The outer surface of the pen barrel 1 has a threaded groove 18, and the inner wall of the pen cap 3 has a threaded protrusion 21 that matches the threaded groove 18. The pen barrel 1 and the pen cap 3 are connected by the threaded groove 18 and the threaded protrusion 21, which allows the pen cap 3 to be easily installed on the top of the pen barrel 1 and ensures that the pen cap 3 will not easily fall off after being tightened. One end of the pen cap 3 is fixedly connected to a silicone sealing cylinder 19, and the high-density fiber pen tip 8 is located inside the silicone sealing cylinder 19. The other end of the silicone sealing cylinder 19 is in contact with the micro ventilation holes 4 opened on the surface of the pen tip 2. When the pen cap 3 is tightened, the silicone sealing cylinder 19 can be closed with the high-density fiber pen tip 8. The fiber tip 8 makes close contact to prevent the eyeliner liquid from drying out, thus extending its service life. The silicone sealing tube 19 can seal the micro vent 4, preventing air from entering the pen barrel 1 through the micro vent 4. The air pressure in the liquid reservoir 11 cannot be balanced, and the eyeliner liquid cannot flow out through the inlet core 10, thus preventing leakage. The inner wall of the pen cap 3 is fixedly connected with a second sealing ring 20. The outer surface of the pen barrel 1 is inlaid with an anti-slip sleeve 22. The outer surface of the anti-slip sleeve 22 has evenly distributed anti-slip textures. The anti-slip sleeve 22 provides an anti-slip grip design, improving the comfort of use.

[0036] In this embodiment, a highly sealed liquid eyeliner pen, through the provision of micro-vent holes 4 and a hydrophobic coating 5, can reduce leakage of liquid eyeliner while ensuring balanced air pressure. The provision of a first sealing ring 6 can reduce the probability of liquid eyeliner leakage from the pen tip 2 and the connecting tube 7. The provision of a first one-way valve 9 and a second one-way valve 13, working together, can limit the flow direction of the fluid inside, preventing external air from entering the interior of the reservoir 11 through the connecting tube 7 and the outlet tube 12. The gas that enters the pen body 1 through the micro-vent holes 4 will enter the interior of the reservoir 11 through the air inlet tube 14 and the third one-way valve 15, thereby achieving the effect of balanced air pressure and ensuring normal delivery of liquid eyeliner. When not in use, the pen cap 3 is installed on the top of the pen body 1, and the pen body 1 and the pen cap 3 form a relatively sealed space between the pen body 1 and the provision of a silicone sealing tube 19, which seals the micro-vent holes 4, preventing the air pressure inside the reservoir 11 from being unbalanced, and preventing the liquid eyeliner from flowing out through the water inlet 10, thereby preventing leakage.

[0037] The working principle of the above embodiment is as follows: When not in use, the pen cap 3 is tightened to one end of the pen barrel 1 through the threaded groove 18 and the threaded protrusion 21. At this time, the silicone sealing cylinder 19 is sleeved on the outside of the high-density fiber pen tip 8, which can prevent the eyeliner liquid from drying out. One end of the silicone sealing cylinder 19 is in contact with multiple micro vent holes 4, achieving a sealing effect on the micro vent holes 4. Furthermore, the second sealing ring 20 can form a sealed space between the pen barrel 1 and the pen cap 3, and the micro vent holes 4 are located in this space. Therefore, air cannot enter the interior of the pen barrel 1 through the micro vent holes 4. If the air pressure cannot be balanced, the eyeliner liquid cannot flow out through the water guide 10, thus preventing leakage. When in use, the pen cap 3 can be unscrewed from the pen barrel 1, and the micro vent 4 will resume communication with the outside. Air enters the interior of the pen barrel 1 through the micro vent 4 to balance the air pressure. By gravity or slight squeezing of the pen barrel 1, the eyeliner liquid is delivered from the reservoir 11 through the water guide 10. The first one-way valve 9 and the second one-way valve 13 can guide the eyeliner liquid evenly into the high-density fiber pen tip 8 for user use. In addition, the hydrophobic coating 5 can prevent the eyeliner liquid from seeping in during use.
