Generally, the liquid in eyeliner is made from natural herbal ingredients, which is safe and healthy. It also has a long-lasting makeup effect, good color, is not easy to smudge, and has smooth lines.

[0003] Application No. 202021293288.3 discloses a leak-proof eyeliner. When the eyeliner is not in use, the user pushes the movable seat to gradually move away from the fixed seat. At this time, the movable seat drives the pen core to detach from the eyeliner liquid, and the movable seat drives the sealing block to seal the through hole through the pen core to reduce the occurrence of eyeliner liquid overflowing through the pen core. When the eyeliner needs to be used, the user pushes the movable seat to approach the fixed seat until the movable seat collides with the fixed seat, the sealing block detaches from the through hole, and the pen core contacts the eyeliner liquid, and the eyeliner liquid soaks the pen core to facilitate the user to use the eyeliner.

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0040] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0042] In the related art, although the eyeliner liquid is removed from the pen core, the eyeliner liquid in the pen core is still not processed and is eventually absorbed by the coated cotton. After the coated cotton is used for a period of time, it can no longer absorb the eyeliner liquid and eventually there will be a contamination problem.

[0043] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a leak-proof eyeliner. Under normal circumstances, the top tube 9 pushes open the conical block 14, so that the eyeliner liquid can flow along the top tube 9 to soak the pen core 6. When the eyeliner is not in use, the nut 10 is rotated to make the screw sleeve 7 drive the pen core 6 to move downward. At this time, the top tube 9 moves downward to make the conical block 14 seal the conical groove 12. When the pen core 6 moves downward, the sliding ring 8 and the rubber ring 11 will also move downward along the cavity 5, at this time, negative pressure is caused above the cavity 5. The cavity 5 with negative pressure will absorb the eyeliner liquid inside the pen core 6, so that when it is not in use, the eyeliner liquid inside the bottom end of the pen core 6 itself will also be extracted. When the nut 10 is rotated in the opposite direction, this part of the eyeliner liquid will soak the pen core 6 again.

[0044] The present application is described below with reference to the accompanying drawings and specific embodiments:
