Description

Pen tool structure with automatic and smooth liquid discharge

technical field

The utility model relates to a pen structure with automatic and smooth liquid discharge, in particular to a pen structure with a spiral groove on the liquid discharge structure, and one end of the spiral groove communicates with the external environment. When the liquid is released and the internal pressure of the pen tube is reduced, external air can be introduced into the pen tube to maintain the balance of the internal air-liquid pressure, so that the liquid can flow out smoothly.

Background technique

At present, eyeliner is a kind of eye makeup technique, which is usually painted around the eye sockets to achieve the effect of modifying the eye contour and make the eyes look deeper. Generally, the eyeliner is drawn through the eyeliner, and the liquid eyeliner is stored in the storage space inside the eyeliner. According to the color of the liquid eyeliner, you can draw eyeliner of different colors; when using the eyeliner, it is necessary to keep the eyeliner out properly. Liquid flow, if the liquid eyeliner flows out too much, it will cause the problem that the liquid is too thick when applying makeup, if the liquid eyeliner flows out too little, it will cause the problem that the liquid will run out and the makeup will not be applied smoothly.

Because liquid makeup pens such as eyeliner or eye shadow pen are often affected by factors such as unstable temperature and air pressure, which will affect the flow of bristles, when the pigment liquid is discharged from the tip of the brush, the inside of the liquid storage space of the pen tube The pressure will form a negative pressure, resulting in a small amount of absorbed liquid in the cotton pen core, and the pen tip will often break out of the liquid. Smooth, usually an air flow channel axially leading to the liquid storage space of the pen tube is formed on the pen tube base.

For example, China Taiwan Patent Publication No. TW M440028 "eyeliner with automatic liquid outlet device", Chinese Taiwan Patent Publication No. TW M549002 "liquid eyeliner with liquid storage function", Chinese Taiwan Patent Publication No. TW M495772 "with integrated cotton Core liquid eyeliner", or Chinese Taiwan Patent Publication No. TW M463535 "Eyeliner with automatic liquid outlet device" and other announcement patents.

It can be known from the aforementioned patents that there are currently related technologies used to improve the smoothness of the eyeliner. However, their structures are quite complicated, and a more complicated process is required when manufacturing or assembling, and when the pen is used for a period of time, the When the amount of pigment liquid in the liquid storage space of the tube gradually decreases, or the pigment liquid does not flow due to the influence of the ambient temperature, the smoothness of the liquid discharge of the cosmetic pencil will be reduced. At this time, the user usually shakes it. When the makeup pen is moved, the pigment liquid leaks from the axial air channel of the pen holder, causing the pigment liquid to spray on the surrounding environment or dirty the cosmetic bag; therefore, how to provide a relatively simple structure that can achieve automatic The structure of the cosmetic pen with the function of liquid discharge and smooth liquid discharge is the direction that the inventor has thought of.

Now, in view of the fact that the structure of the above-mentioned existing makeup pen still has many defects in actual implementation and use, the inventor is a tireless spirit, assisted by his rich professional knowledge and many years of practical experience, and Improve it, and research and create the utility model accordingly.
