Rollerball pens and liquid eyeliner pens are cosmetic pens with a liquid storage function inside the pen tube, and are used through a roller ball head assembly or a brush head assembly at the end of the pen tube. Some existing lipstick pens also use the above-mentioned roller ball pen and liquid eyeliner pen liquid storage and roller ball head assembly structural design, such as the application number 201820921240.9 disclosed in the Chinese patent literature, the authorization announcement date is 2019.01.11, and the utility model name is "A Lipstick Pen"; the lipstick pen includes a cylindrical bottle body, the top opening of the cylindrical bottle body is provided with a ball-type discharging device, and the discharging device includes a hollow discharging barrel installed at the top opening of the cylindrical bottle body, and the upper end of the hollow discharging barrel is provided with a diameter-reducing discharging device. The hollow discharge barrel is provided with an inner barrel seat, and a discharge channel is provided in the middle of the inner barrel seat along the axial direction. The top of the inner barrel seat is provided with an arc surface for ball rolling, and the top of the discharge channel is connected to the arc surface. A ball is provided between the arc surface and the narrowing discharge port. A piston is provided in the cylindrical bottle body, and the bottom of the piston is connected to a threaded rod. The cylindrical bottle body is provided with a fixed nut that cooperates with the threaded rod. The bottom of the cylindrical bottle body is rotatably connected to a drive base for driving the threaded rod. However, the ball and spring are provided in the head of the pen barrel below the ball of the above-mentioned product, which is easy to react with the liquid in the pen barrel or cause blockage. The overall shell lacks a metal shell and aluminum label design, and the hand feel is poor during use. Therefore, the above-mentioned product and similar products need further improvement and perfection. Summary of the Invention
[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide a diamond-shaped knurled aluminum-label rotating cosmetic brush in the art. This design primarily addresses the technical issues of existing similar products, such as the limited use of an external spring structure within the pen barrel, which can easily lead to internal liquid deterioration and clogging, and the lack of a metal outer shell and aluminum label design, resulting in a poor feel during use. This objective is achieved through the following technical solution.
[0004] A diamond-shaped knurled aluminum label rotating cosmetic brush, the pen barrel of the rotating cosmetic brush is a double-pass inner tube, one end of the double-pass inner tube is provided with a ball head assembly or a brush head assembly, and a piston is provided in the double-pass inner tube; the piston rod at the bottom of the piston extends out of the external spring assembly at the other end of the double-pass inner tube and is connected to the rotating base assembly; the key points of its structural design are that the external spring assembly includes an upper inner sleeve, a lower spring, a lower inner sleeve and a rod sleeve, and the upper inner sleeve, lower spring, lower inner sleeve and rod sleeve are encapsulated in the double-pass inner tube through a cover at one end of the rotating base assembly of the double-pass inner tube; the movable The flat key surfaces on both sides of the plug rod's outer diameter sequentially penetrate the upper inner sleeve, lower spring, and lower inner sleeve and are inserted into the first flat key hole in the center of the rod sleeve. The flat key head at the end of the rod sleeve extends out of the sleeve cover of the double-pass inner tube and connects to the second flat key hole of the rotating base assembly as a whole. The two ends of the lower spring, which is set inside the double-pass inner tube and at the outer diameter of the connection between the piston rod and the rod sleeve, respectively abut against the upper and lower inner sleeves. The upper inner sleeve limits the outer diameter of the piston rod below the piston, while the lower inner sleeve limits the outer diameter at one end of the rod sleeve. The upper inner sleeve abuts against the inner wall of the double-pass inner tube, and the lower inner sleeve abuts against the inner wall of the sleeve cover extending into the double-pass inner tube. Therefore, rotating the rotating base assembly at the bottom can drive the internal piston upward through the piston rod, helping the spring to squeeze out the liquid.
[0005] The middle diameter of the rod sleeve is larger than the diameters of the two end diameters. A toothed ring is provided on the step between the middle diameter and the top end diameter. The toothed ring engages with the teeth or ribs on the annular ring at the bottom of the inner opening of the lower inner sleeve. This creates a damping effect and stops rotation during rotation, and prevents rebound after rotation.
[0006] The outer diameter of the double-pass inner tube is provided with an integral double-pass inner and outer tube, and the outer diameter of the double-pass inner and outer tube is provided with a metal outer tube. The rotating base assembly includes a lower cover and a metal bottom cover, which are integrally connected and sleeved together. The outer diameter of the metal bottom cover is provided with a knurled pattern, and the metal bottom cover is cylindrical with the metal outer tube and the pen cap assembly. The double-pass inner and outer tubes can be omitted as needed, and the outer diameter of the double-pass inner tube can be directly provided with the metal outer tube. The metal bottom cover, metal outer tube, and the following metal outer cover are primarily made of alumina.
[0007] An aluminum plate is provided on one side of the outer diameter of the metal outer tube, so as to facilitate the display and presentation of logos such as trademarks.
[0008] The pen cap assembly has a metal outer cap with an inner cap integrally connected to it. One end of an upper spring fixed to the inner top of the inner cap is integrally connected to the outer diameter of the inner top cover. The metal outer cap, inner cap, upper spring, and top cap are integrally connected. The cover opening of the top cap is snap-fitted or threadedly connected to the lower part of the ball bearing assembly or the lower part of the brush head assembly. The above structure is an embodiment of a double-cap structure for the pen cap assembly. It can also adopt a structure with a metal outer cap on the outer diameter of the cap.
[0009] The utility model has reasonable structural design, is easy to use, has a long service life, good sealing performance, and a good hand feel when used; it is suitable for use as a diamond knurled aluminum plate rotating cosmetic brush with a ball head assembly or a brush head assembly, and is a structural improvement of similar products.
