Abstract

A press-type makeup pen includes a nib assembly, a body assembly, a discharge assembly, and a drive assembly, where the nib assembly includes a sleeve; the discharge assembly includes a material loading member and a threaded rod; the sleeve is rotatably provided in the body assembly; the drive assembly is provided in the body assembly; the material loading member is threadedly connected to the threaded rod; the threaded rod is threadedly connected to the drive assembly; the sleeve can drive the material loading member to rotate synchronously, such that the material loading member moves along an axial direction of the threaded rod to retract into the threaded rod; and the drive assembly can drive the threaded rod to move toward a free end of the sleeve along an axial direction of the sleeve. A button of the drive assembly is provided on a tail portion of the makeup pen.

First claim

The invention claimed is:

the sleeve is unidirectionally rotatable in the body assembly.

2 . The press-type makeup pen according to claim 1 , wherein the sleeve is axially fixed in the body assembly; and the sleeve is configured to drive the material loading member to move toward the drive assembly.

3 . The press-type makeup pen according to claim 1 , wherein the body assembly comprises a barrel and a coupling member, wherein the barrel and the coupling member are fixedly connected; an elastic tooth is provided on the sleeve; a first oblique surface and a first straight surface are provided on the elastic tooth; a sawtooth is provided on an inner peripheral wall of the barrel; a second oblique surface and a second straight surface are provided on the sawtooth; the first oblique surface is configured to slide on the second oblique surface; and the first straight surface is stopped at the second straight surface.

4 . The press-type makeup pen according to claim 3 , wherein a mounting groove is formed in the sleeve; the elastic tooth is provided in the mounting groove; a first end of the elastic tooth is fixedly connected to the sleeve, and a second end of the elastic tooth is a free end; the first straight surface is located at the second end of the elastic tooth; and the first oblique surface is located on an outer surface of the elastic tooth.

5 . The press-type makeup pen according to claim 1 , wherein the material loading member comprises a material loading cylinder and a connecting rod fixed on the material loading cylinder; the material loading cylinder is circumferentially fixed and axially movable in the sleeve; and the connecting rod is threadedly connected to the threaded rod.

6 . The press-type makeup pen according to claim 5 , wherein an outer peripheral wall of the connecting rod is provided with a first external thread; a cavity is formed in the threaded rod; an inner peripheral wall of the threaded rod is provided with a first internal thread, and an outer peripheral wall of the threaded rod is provided with a second external thread; the connecting rod is inserted into the cavity; and the first external thread cooperates with the first internal thread.

7 . The press-type makeup pen according to claim 5 , wherein after the connecting rod retracts into the threaded rod completely, the threaded rod abuts against a bottom of the material loading cylinder.

8 . The press-type makeup pen according to claim 1 , wherein the drive assembly comprises a button, a ratchet, a ratchet seat, a ratchet wheel, an elastic member, and a rotating member; the ratchet is fixedly provided in the button; the ratchet and the ratchet wheel are movably provided in the ratchet seat; the ratchet is engaged with the ratchet wheel; the rotating member is sleeved on the threaded rod and threadedly connected to the threaded rod; the rotating member abuts against the body assembly; the elastic member is provided between the rotating member and the ratchet wheel; the ratchet is configured to drive the ratchet wheel to rotate, and the ratchet wheel is configured to drive the rotating member to rotate, such that the rotating member drives the threaded rod to move away from the button.

9 . The press-type makeup pen according to claim 8 , wherein a first latch is provided on the ratchet; a second latch and a first pawl are provided on the ratchet wheel; a second pawl is provided on the rotating member; an inner peripheral wall of the rotating member is provided with a second internal thread; the first latch is engaged with the second latch; a gap is formed between two adjacent first pawls; and the second pawl is inserted into the gap to realize synchronous rotation of the rotating member and the racket wheel.

10 . The press-type makeup pen according to claim 2 , wherein the drive assembly comprises a button, a ratchet, a ratchet seat, a ratchet wheel, an elastic member, and a rotating member; the ratchet is fixedly provided in the button; the ratchet and the ratchet wheel are movably provided in the ratchet seat; the ratchet is engaged with the ratchet wheel; the rotating member is sleeved on the threaded rod and threadedly connected to the threaded rod; the rotating member abuts against the body assembly; the elastic member is provided between the rotating member and the ratchet wheel; the ratchet is configured to drive the ratchet wheel to rotate, and the ratchet wheel is configured to drive the rotating member to rotate, such that the rotating member drives the threaded rod to move away from the button.

11 . The press-type makeup pen according to claim 3 , wherein the drive assembly comprises a button, a ratchet, a ratchet seat, a ratchet wheel, an elastic member, and a rotating member; the ratchet is fixedly provided in the button; the ratchet and the ratchet wheel are movably provided in the ratchet seat; the ratchet is engaged with the ratchet wheel; the rotating member is sleeved on the threaded rod and threadedly connected to the threaded rod; the rotating member abuts against the body assembly; the elastic member is provided between the rotating member and the ratchet wheel; the ratchet is configured to drive the ratchet wheel to rotate, and the ratchet wheel is configured to drive the rotating member to rotate, such that the rotating member drives the threaded rod to move away from the button.

12 .
