A liquid eyeliner pen having a liquid storage function, comprising a container assembly configured to contain an eyeliner liquid, an applying assembly configured to draw the eyeliner liquid to flow out and apply the eyeliner liquid onto a user's face, and a cap assembly;
- wherein the applying assembly comprises a brush sleeve base, a brush sleeve, a diverter base;
- a coupling, a liquid feeder, and a brush positioned and coupled to a shaft end of the liquid feeder;
- the brush sleeve base, the brush sleeve, the diverter base;
- and the coupling are coaxially arranged and are all sleeve-shaped structures with openings at both ends in an axial direction;
- a rear shaft end of the brush sleeve and a front shaft end of the coupling are correspondingly positioned and inserted into a front shaft end and a rear shaft end of the brush sleeve base, respectively;
- the diverter base is configured inside the brush sleeve base and is located between the brush sleeve and the coupling;
- two ends of the diverter base in the axial direction respectively abut against the rear shaft end of the brush sleeve and the front shaft end of the coupling;
- the brush sleeve, the diverter seat, and the coupling further collectively form an accommodating cavity;
- the liquid feeder and the brush are coaxially positioned and inserted into the accommodating cavity together, and a part of the brush further extends outside a front shaft end of the brush sleeve;
- an outer sidewall of the brush sleeve base radially extends outward to form a round of first protruding edge;
- the round of first protruding edge divides the brush sleeve base into a first portion corresponding to the coupling and a second portion corresponding to the brush sleeve;
- the first portion of the brush sleeve base is inserted into the container assembly and is detachably positioned and coupled with the container assembly;
- the cap assembly is detachably sleeved outside the second portion of the brush sleeve base;
- characterized in that the brush sleeve has a brush sleeve body, and the brush sleeve body is a sleeve-shaped structure with openings at both ends in the axial direction;
- at least one air inlet hole extending along the axial direction of the brush sleeve body and running through the brush sleeve body is configured on the brush sleeve body at a position close to a front shaft end thereof, and a front side of the air inlet hole is exposed outside the brush sleeve base;
- at least one first air vent extending along the axial direction of the brush sleeve body is further formed on an outer layer sidewall of the brush sleeve body;
- a front side of the first air vent intercommunicates with the air inlet hole;
- a rear side of the first air vent intercommunicates with a second air vent on the diverter base;
- and wherein
- at least one liquid storage groove unit is configured on an inner layer sidewall of the brush sleeve body;
- each liquid storage groove unit is composed of a plurality of arc-shaped liquid storage grooves extending along a circumferential direction of the brush sleeve body, and the plurality of arc-shaped liquid storage grooves of each liquid storage groove unit are further arranged along the axial direction of the brush sleeve body at intervals.
