[0002] As a makeup product, the eyeliner pen has been widely used at present. There are already some eyeliner pen brands on the market that provide a design with replaceable pen tips, but not all products support the matching of pen tips with various shapes and thicknesses. Therefore, when purchasing, it is necessary to pay attention to the specific specifications and accessories of the product. Many high-end or professional-grade eyeliner pens on the market adopt a high-concentration ink formula to ensure the durability and color rendering of the makeup. Considering the use characteristics of the eyeliner pen and market demand, large particle ink may not be an ideal choice for the design of the eyeliner pen. However, certain special effects or creative makeup may require this texture of ink to achieve specific visual effects. However, the current liquid eyeliner pens, although relatively convenient to use and easy to operate, also have some relatively common problems. There are also some eyeliner pens on the market that use ink with a higher concentration and more particles, but it is easy to have problems such as uneven liquid volume at the working end (brush pen tip) or even no liquid in some parts. The liquid volume at the working pen tip is uneven, the liquid replenishment is unstable, and the fluidity of the eyeliner pen's liquid output is lacking. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 - 13 , the present invention is an eyeliner pen water storage device structure for multiple pen tips and ultra-high viscosity large particle inks, including a pen body, the pen body includes a pen cap 1, an inner plug 2, a spring 8, a large pen tip seat 3, a water storage device 4, an inner rod 5, an outer rod 7, a pen tip 9, a base 10, an ink guiding core 11, a stainless steel ball 6 and a tail plug 12. The head of the water storage device 4 has a multi-segment sealing structure in its outer shape. Referring to Figures 2 - 7 , it can be matched with the shapes of various large pen tip seats 3, and the water storage device 4 is completely sealed with the inner hole of the base 10. Under high or low temperatures, or negative pressure conditions, the ink will not overflow from the mouth of the water storage device 4 and the inner hole of the base 10;

[0032] Inside the inner cavity of the large pen tip holder 3, there is an inner rod 5. The inner rod 5 includes a core-piercing section and a housing section. At the tail of the inner rod 5, there is a stainless steel ball 6. A sealing tail plug 12 is provided on the housing section. A liquid storage chamber is formed between the inner wall of the housing section of the inner rod 5 and the water storage device 4. Inside the inner cavity of the pen tip 9, there is a water guiding core 11. There is a whole-section large-gap fit between the inner hole of the water storage device 4 and the water guiding core 11. The assembly of the water guiding core 11 is more convenient and not prone to deformation, which is beneficial to the fluidity of the ultra-high-viscosity large-particle ink. In the middle of the inner hole of the water storage device 4, there is a multi-section ultra-long and widened air return groove 13 inside the cavity. Different from the general air return groove width of 0.1 mm and below, the width of the multi-section ultra-long and widened air return groove 13 inside the cavity in this application is more than 0.15 mm. And on the outer side wall of the water storage device 4, there is a large-inclination side exhaust groove 14. Two support blocks 15 are evenly distributed on the inner wall of the water storage device 4, which is more beneficial to the exhaust of the ultra-high-viscosity large-particle ink and prevents situations such as ink overflow from the pen tip 9. There is a whole-section circular seal between the tail of the water storage device 4 and the inner rod 5, so that the ultra-high-viscosity large-particle ink can only be led to the pen tip 9 through the water guiding core 11 for ink output, improving the sealing performance and fluidity of the ink in the liquid storage chamber. At the bottom position of the water storage device 4, there is a support ring for positioning and supporting the water guiding core 11, and the head of the water guiding core 11 is completely inserted into the pen tip 9, effectively preventing the up and down movement of the water guiding core 11. And the bottom end of the water guiding core 11 is below the inner hole of the water storage device 4. When in use, the ultra-high-viscosity large-particle ink in the liquid storage chamber is completely led to the pen tip 9 through the water guiding core 11, improving the fluidity and continuity of the ink.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
