Description

Pen structure with automatic smooth liquid discharge

The present invention relates to a writing instrument structure with automatic smooth liquid discharge, in particular to a writing instrument structure in which a spiral groove is formed in a liquid discharging structure, and one end of the spiral groove is connected with the external environment, when the liquid is from the pen tip When the liquid pressure is lowered and the internal pressure of the pen tube is lowered, external air can be introduced into the pen tube to maintain the balance of the internal gas-liquid pressure, so that the liquid can smoothly flow out.

Press, the eyeliner is an eye makeup technique that is usually painted around the eyelids to achieve the effect of modifying the contours of the eyes, while making the eyes look deeper. Generally, the eyeliner is drawn through the eyeliner, and the eyeliner is stored in the accommodating space inside the eyeliner. According to the color of the eyeliner, the eyeliner of different colors can be drawn; when the eyeliner is used, it is necessary to maintain the proper eyeliner. Fluency, if the eyeliner is excessively flowed out, there is a problem that the liquid is too thick when applying makeup. If the eyeliner flows too little, there is a problem that the liquid is not smoothly applied.

Due to liquid makeup pens such as eyeliner or eye shadow pen, it is often subject to factors such as temperature and air pressure instability, which in turn affects the flow rate of the bristles. When the pigment liquid is discharged from the tip of the brush, the pen tube storage space The internal pressure will form a negative pressure, which will cause the amount of adsorbed liquid in the cotton refill to be small, and the liquid discharge from the nib will often occur. In order to maintain the balance of the gas-liquid pressure inside the liquid storage space of the pen tube and the brush out The liquid is smooth, usually in the pen tube seat formed with an air flow path axially passing through the liquid storage space of the pen tube.

For example, the Republic of China Patent Publication No. TW M440028 "eyeliner with automatic liquid discharge device", Republic of China Patent Publication No. TW M549002 "Liquid Eyeliner with Liquid Storage Function", Republic of China Patent Notice No. TW M495772 "with integrated cotton The core liquid eyeliner", or the Republic of China Patent Publication No. TW M463535 "eyeliner with automatic liquid discharge device" and other announcement patents.

It can be seen from the foregoing patents that the related art has been used to improve the fluid discharge smoothness of the eyeliner. However, the structure is quite complicated, and it requires a complicated process in manufacturing or assembly, and when used for a period of time, When the amount of the pigment liquid in the liquid storage space of the pen tube gradually decreases, or the effect of the ambient temperature causes the pigment liquid to be relatively non-flowing, the fluidity of the makeup pen is reduced, and at this time, the user usually Shaking and shaking the makeup pen, causing the pigment liquid to ooze out from the axial air flow passage of the pen holder, causing the pigment liquid to be sprayed on the surrounding environment or soiling the cosmetic bag; thus, how to provide a simple structure and reach The structure of the makeup pen with automatic liquid discharge and smooth liquid discharge function is the direction that the creator thinks.

Today, the creator is still in the light of the indefatigable spirit of the structure of the above-mentioned existing stylus, and it is supplemented by its rich professional knowledge and years of practical experience. Improve, and based on this, create this creation.
