Abstract

A leakage-proof cosmetic pen tip comprises a liquid outlet formed on a pen tip holder in such a manner that the exit of the liquid outlet is arranged at the middle part of the pen tip; a pen tip cover wraps the rear part of the pen top and is fixedly connected with the pen top holder, so that the pen tip is fixed on the pen tip holder; and a rear cover fixed on the pen tip. The leakage-proof cosmetic pen tip is characterized in that a spring seat is fixed in the middle cavity of the pen tip holder through four fixing claws; four liquid tanks are formed among the fixing claws; a spring is arranged in the spring seat; and the inner circle of a piston sleeve is connected with the outer circle of the spring seat in a movable sealed manner. Compared with the prior art, the leakage-proof cosmetic pen tip has the remarkable advantages that the spring is completely separated from the solution due to the movable sealed connection between the inner circle of the piston sleeve and the outer circle of the spring holder, so that the spring can be expanded and restored completely after being compressed, thereby achieving good anti-leakage function of the cosmetic pen tip and improving the performance of the cosmetic pen.

Description

Anti-leakage type cosmetic pencil nib

Technical field

The utility model relates to a kind of daily living article, particularly a kind of Anti-leakage type cosmetic pencil nib.

Background technology

All be equipped with spring in the existing Anti-leakage type nib, spring is metal and is immersed in the solution, because solution has certain consistency, can not unfold answer completely after spring is pressed, make the ball on the spring can not seal the import inclined-plane, cause the forfeiture of drip-preventing function then.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes existing defective in the above-mentioned prior art, provides a kind of spring and solution to separate fully, good seal performance cosmetic pencil nib.

A kind of Anti-leakage type cosmetic pencil nib, nib seat is provided with fluid hole, and the outlet of fluid hole places the middle part of nib, and the nib cover wraps up the rear portion of nib and fixedlys connected with the nib seat, the nib cover also is fixed on nib on the nib seat simultaneously, and bonnet is fixed on the tail end of nib seat; It is characterized in that by several fixed claw fixing spring seats, several logical liquid baths being arranged between the fixed claw in the nib seat middle cavity, spring base is built-in with spring, is movable sealing on circle and the spring base cylindrical in the piston bush and is connected.

The utility model is compared with prior art has tangible advantage and positive effect, be connected owing to being movable sealing on the outer garden of circle in the piston bush and spring base, spring and solution are separated fully, after being pressed, spring can unfold answer completely, the serviceability of cosmetic pencil has improved so that the cosmetic pencil head has drip-preventing function completely in institute.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model user mode;

Accompanying drawing 2 is the utility model structural representation.

1 nib, 2 nib covers, 3 nib seats, 3.1 fluid holes, 4 spring bases, 4.1 logical liquid baths, 4.2 fixed claws, 5 springs, 6 piston bush, 7 bonnets, 7.1 bonnet holes.

The specific embodiment

The utility model will be further described below in conjunction with embodiment and accompanying drawing.

With reference to Fig. 1～Fig. 2, a kind of Anti-leakage type cosmetic pencil nib, nib seat 3 is provided with fluid hole 3.1, the outlet of fluid hole 3.1 places the middle part of nib 1, nib cover 2 rear portions with nib 1 wrap up and fixedly connected with nib seat 3, nib cover 2 also is fixed on nib 1 on the nib seat 3 simultaneously, and bonnet 7 is fixed on the tail end of nib seat 3; It is characterized in that by four fixed claw 4.2 fixing spring seats 4, four logical liquid baths 4.1 being arranged between the fixed claw 4.2 in nib seat 3 middle cavities, spring base 4 is built-in with spring 5, is movable sealing on circle and spring base 4 cylindricals in the piston bush 6 and is connected; Described piston bush 6 inner chambers are provided with toroidal cavity, and spring base 4 tail ends flexibly connect groove; The nose circle face leans spring 5 in the groove, and piston bush 6 outer faces are conical protrusions, is connected with inclined-plane movable sealings in the hole 7.1 on the bonnet 7.

Solution produces under the effect of external force and flows, and mobilization force makes piston bush 6 compression springs 5 produce displacement after acting on piston bush 6, makes solution pass through the inner chamber that bonnet hole 7.1 flows into nib seat 3; After external force stopped, inclined-planes contacted in the hole 7.1 on piston bush 6 end face conical protrusions and the bonnet 7, and homing plays the effect of sealing.
