Abstract

A multi-color press-type cosmetic pen includes a cylindrical pen body, a pen tip, and at least two actuating mechanisms. Each actuating mechanism includes a button, a ratchet, a ratchet wheel, a screw rod, a nut, a piston, and a spring. The button is fixed to the ratchet. Each of the ratchet and the ratchet wheel is hollow and cylindrical. The ratchet wheel is inserted into the ratchet. At least one inclined surface is provided on the outer peripheral wall of the ratchet wheel, and an abutting portion matched with the inclined surface is provided on the inner peripheral wall of the ratchet. The screw rod is inserted in the ratchet wheel. The nut is fixed on the pen body. The piston is mounted on the head the upper end of the screw rod. The spring abuts between the nut and the ratchet wheel.

First claim

What is claimed is:

1. A multi-color press-type cosmetic pen, comprising a cylindrical pen body, a pen tip mounted at a front end of the cylindrical pen body, and at least two actuating mechanisms mounted at a tail end of the cylindrical pen body; wherein
each actuating mechanism of the at least two actuating mechanisms comprises a button, a ratchet, a ratchet wheel, a screw rod, a nut, a piston, and a spring;
the button is fixed to the ratchet; each of the ratchet and the ratchet wheel is hollow and cylindrical;
the ratchet wheel is inserted into the ratchet;
at least one inclined surface is provided on an outer peripheral wall of the ratchet wheel, and an abutting portion matched with the at least one inclined surface is provided on an inner peripheral wall of the ratchet;
the screw rod is inserted in the ratchet wheel, and an outer wall of the screw rod is provided with a circular external thread;
the nut is fixed on the cylindrical pen body, and an inner wall of the nut is provided with a circular internal thread;
an upper end of the screw rod is exposed outside the ratchet wheel, and the circular external thread of the screw rod is engaged with the circular internal thread of the nut;
the piston is mounted on a head of the upper end of the screw rod; and
the spring abuts between the nut and the ratchet wheel.

2. The multi-color press-type cosmetic pen according to claim 1 , wherein an inner peripheral wall of the ratchet wheel forms a special-shaped cavity.

3. The multi-color press-type cosmetic pen according to claim 1 , wherein a pen tip base is arranged above the cylindrical pen body; the pen tip is partially embedded into the pen tip base, and the pen tip is partially exposed outside the pen tip base.

4. The multi-color press-type cosmetic pen according to claim 3 , wherein a cover is arranged above the cylindrical pen body, and the cover is configured to cover the pen tip; an inner peripheral wall of the cover is provided with an internal thread, and an outer wall of the pen tip base is provided with an external thread; and the internal thread of the cover is engaged with the external thread of the pen tip base.

5. The multi-color press-type cosmetic pen according to claim 1 , further comprising a tail plug, wherein an upper part of the tail plug is connected to the cylindrical pen body, and a lower part of the tail plug forms a receiving spaces to receive the buttons.

6. The multi-color press-type cosmetic pen according to claim 5 , wherein the at least two actuating mechanisms are two actuating mechanisms, the cylindrical pen body is provided with two liquid material receiving cavities, and the two actuating mechanisms are arranged under the two liquid material receiving cavities, respectively; the two actuating mechanisms are arranged side by side from left to right; the pen tip is provided with two discharge holes corresponding to the two actuating mechanisms, and two buttons are provided in the two actuating mechanisms, respectively; and the lower part of the tail plug forms two receiving spaces corresponding to the two buttons.

7. The multi-color press-type cosmetic pen according to claim 5 , wherein the at least two actuating mechanisms are four actuating mechanisms, the cylindrical pen body is provided with four liquid material receiving cavities, and the four actuating mechanisms are arranged under the four liquid material receiving cavities, respectively; the four actuating mechanisms are arranged in pairs side by side from front to back and from left to right; the pen tip is provided with four discharge holes corresponding to the four actuating mechanisms, and four buttons are provided in the four actuating mechanisms, respectively; and the lower part of the tail plug forms four receiving spaces corresponding to the four buttons.
