Description

Pen structure with automatic and smooth liquid discharge

Technical Field

The utility model relates to a have automatic pen utensil structure that smoothly goes out liquid, especially indicate the pen utensil structure of seting up spiral slot on going out the liquid structure, and the one end of spiral slot can communicate with external environment, goes out liquid and under the circumstances that the pen tube internal pressure reduces by the nib when liquid, can channel into the balance in order to keep inside gas-liquid pressure power in getting into the pen tube by the nib, lets liquid can smoothly flow out.

background

At present, eyeliner is a kind of eye makeup skill, and it is usually painted around the eye orbit to achieve the effect of modifying the contour of the eye, so that the eyes look deeper. Generally, eyeliners are drawn through an eyeliner pen, eyeliner liquid is stored in an accommodating space inside the eyeliner pen, and eyeliners with different colors can be drawn according to the colors of the eyeliner liquid; when the eyeliner is used, the liquid outflow fluency of the eyeliner needs to be kept properly, if the eyeliner flows out too much, the problem that the liquid is too thick during makeup is caused, and if the eyeliner flows out too little, the problem that the liquid is broken and the makeup cannot be smoothly carried out is caused.

Because the liquid cosmetic pencil like an eyeliner or an eye shadow pencil usually suffers from unstable temperature and air pressure and other factors, and further influences the discharge flow of the brush bristles, when pigment liquid is discharged from the tip of the pencil brush, the internal pressure of the liquid storage space of the pencil tube can form negative pressure, so that the amount of the absorbent liquid of the cotton pencil core is less, the phenomenon of material break can be frequently caused when the pen tip discharges the liquid, and in order to keep the balance of the internal air-hydraulic pressure of the liquid storage space of the pencil tube and the smooth liquid discharge of the pencil brush, an air flow channel which is axially communicated in the liquid storage space of the pencil tube is usually formed on the pencil tube base.

for example, taiwan patent publication No. TW M440028 "eyeliner with automatic liquid discharging device", taiwan patent publication No. TW M549002 "liquid eyeliner with liquid storing function", taiwan patent publication No. TW M495772 "liquid eyeliner with integrated cotton core", or taiwan patent publication No. TW M463535 "eyeliner with automatic liquid discharging device", and the like are issued.

As can be seen from the above mentioned patents, there are related technologies for improving the smoothness of discharging liquid from an eyeliner, however, the structure of the related technologies is complicated, and a complicated process is required during manufacturing or assembling, and when the related technologies are used for a period of time, the amount of pigment liquid in the liquid storage space of the pen tube gradually decreases, or the pigment liquid is not flowed due to the influence of environmental temperature, the smoothness of discharging liquid from the cosmetic pen will decrease, and at this time, the user will shake the cosmetic pen, causing the pigment liquid to seep out from the axial air channel of the pen tube holder, which leads to the situation that the pigment liquid is sprayed to the surrounding environment or dirties the cosmetic bag; therefore, how to provide a cosmetic pen structure with a simple structure and functions of automatic liquid discharge and smooth liquid discharge is the direction the inventor thinks.
