[0034] Reference below Figure 1-Figure 5 The following describes a push-type automatic cosmetic brush according to an embodiment of the utility model.

[0035] like Figure 1-Figure 5 As shown, the push-type automatic cosmetic pen includes a pen housing 200, a pen head 110 and a push structure, one end of the pen housing 200 is connected to the pen head 110, and the other end is provided with a push structure. A liquid storage chamber 210 is provided between the push structure and the pen head 110, and the pen liquid is stored in the liquid storage chamber 210.

[0036] Specifically, the pressing structure includes a piston member 310, a piston rod 320 connected to the piston member 310, and a sleeve portion 330 driving the piston rod 320 to move. The sleeve portion 330 reciprocates in the pen housing 200 and drives the piston rod 320 and the piston member 310 to perform a rotational feeding motion to squeeze the liquid storage chamber 210.

[0037] The end of the piston 310 facing the liquid storage chamber 210 is bowl-shaped, and the end connected to the piston 310 is also bowl-shaped, so that both ends of the piston 310 can fit with the inner wall of the pen housing 200, improve the sealing performance, and keep the air pressure in the liquid storage chamber 210 stable. The piston 310 is sleeved with the end of the piston rod 320. When the piston rod 320 performs a rotary feeding motion, the piston 310 can be pushed by the piston rod 320 instead of rotating with the piston rod 320, reducing the circumferential friction frequency between the piston 310 and the inner wall of the pen housing 200. The piston 310 only performs an axial feeding motion in the pen housing 200, which has better sealing performance, reduces the wear of the piston 310 and prevents external air from entering the liquid storage chamber 210 to cause poor liquid discharge. The sleeve portion 330 reciprocates in the pen housing 200 along the internal channel direction of the pen housing 200 to drive the piston rod 320 to feed.

[0038] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the pressing structure further includes a pressing seat 340 , and a limiting base 350 and a limiting top seat 360 are respectively provided at both ends of the pressing seat 340 , and the sleeve portion 330 reciprocates between the limiting base 350 and the limiting top seat 360 .

[0039] Specifically, the pressing seat 340 is fixedly connected to the end of the pen housing 200, and a limiting base 350 and a limiting top seat 360 are provided at both the front and rear ends of the pressing seat 340. A movable space is formed between the limiting base 350 and the limiting top seat 360, and the sleeve part 330 reciprocates in the movable space.

[0040] Furthermore, if Figure 1-Figure 3 As shown, the limiting base 350 is provided with a rotating tooth 351, and the limiting top seat 360 is provided with an anti-backward tooth 361. The rotating tooth 351 and the anti-backward tooth 361 are arranged opposite to each other, and the rotating tooth 351 and the anti-backward tooth 361 are arranged alternately. The two ends of the sleeve part 330 are respectively provided with a feeding tooth 331 and a limiting tooth 332. The feeding tooth 331 is meshed with the rotating tooth 351, and the limiting tooth 332 is meshed with the anti-backward tooth 361. When the feeding tooth 331 is meshed with the rotating tooth 351, the sleeve part 330 drives the piston rod 320 to rotate, and when the limiting tooth 332 is meshed with the anti-backward tooth 361, the sleeve part 330 is prevented from rotating.

[0041] Specifically, in order to convert the reciprocating motion of the sleeve part 330 into the feeding motion of the piston rod 320, each time the feeding teeth 331 of the sleeve part 330 mesh with the rotating teeth 351, the sleeve part 330 will rotate a certain angle in the circumferential direction, thereby driving the piston rod 320 to rotate. When the sleeve part 330 is reset and abuts against the limiting top seat 360, the sleeve part 330 will not reverse in the circumferential direction under the meshing action of the limiting teeth 332 and the anti-backward teeth 361, thereby ensuring that each movement of the sleeve part 330 can drive the piston rod 320 to rotate a certain angle.

[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a reset elastic member 380 is provided between the sleeve portion 330 and the limiting base 350 , and the reset elastic member 380 is used to push the sleeve portion 330 to abut against the limiting top seat 360 .

[0043] Specifically, a truncated cone extends from the side wall of the sleeve portion 330 and abuts against one end of the reset elastic member 380, and a circle of truncated cones is provided on the side wall of the position limiting base 350 and sleeved with one end of the reset elastic member 380. That is, one end of the reset elastic member 380 is fixed on the position limiting base 350. When the sleeve portion 330 is pressed toward the position limiting base 350, the reset elastic member 380 is compressed. When the external force of the sleeve portion 330 is removed, the reset elastic member 380 recovers its deformation and pushes the sleeve portion 330 to move toward the position limiting top seat 360. The fixing of one end of the reset elastic member 380 to the position limiting base 350 can prevent the reset elastic member 380 from shaking in the activity space of the pressing seat 340 to produce abnormal noise and affect the texture of use.

[0044] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the sleeve portion 330 passes through the limiting top seat 360 and is sleeved with a pressing cover 370 , and the pressing cover 370 pushes the sleeve portion 330 downward to abut against the limiting base 350 .

[0045] Specifically, a hole is opened in the middle of the position limiting top seat 360, the sleeve portion 330 extends outward through the hole, and the pressing cover 370 is connected to the sleeve portion 330. When the pressing cover 370 abuts against the position limiting top seat 360 during the pressing process, the pressing cover 370 reaches the end of the stroke, and after the pressing cover 370 is released, it is reset under the action of the reset elastic member 380, and this process is repeated to make the sleeve portion 330 rotate continuously.

[0046] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, a threaded hole is provided in the middle of the limiting base 350, and the piston rod 320 is provided with threads. The piston rod 320 is threadedly connected to the limiting base 350. When the sleeve portion 330 drives the piston rod 320 to rotate, the piston rod 320 feeds toward the liquid storage chamber 210.

[0047] Specifically, the piston rod 320 and the sleeve portion 330 rotate synchronously, and the piston rod 320 is threadedly connected to the limiting base 350 , so that the piston rod 320 is fed toward the liquid storage chamber 210 .

[0048] In some embodiments of the present invention, Figure 1 and Figure 4As shown, the piston rod 320 is slidably connected with the sleeve portion 330, and the cross section of the sleeve portion 330 at the connection is runway-shaped, and the cross section of the piston rod 320 matches the cross section of the sleeve portion 330 at the connection. Specifically, the sliding connection between the piston rod 320 and the sleeve portion 330 can separate the linkage with the piston rod 320 during the retreat of the sleeve portion 330. If the piston rod 320 is tightly connected with the sleeve portion 330, the piston rod 320 will be pulled when the sleeve portion 330 is reset, and the piston rod 320 is screwed with the limiting base 350, so that the sleeve portion 330 cannot be reset normally. In this embodiment, the sleeve portion 330 is only used to drive the piston rod 320 to rotate, and the feeding movement of the piston rod 320 is realized by the thread of the limiting base 350.

[0049] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, the pen head 110 is provided with a liquid outlet brush head 111, and the liquid outlet brush head 111 is connected to the liquid storage chamber 210. Specifically, the material and structure of the liquid outlet brush head 111 are technical solutions well known to those skilled in the art, and will not be described in detail in this embodiment.

[0050] Furthermore, if Figure 5 As shown, the liquid discharge brush head 111 is flat. The liquid discharge brush head 111 is tilted at a certain angle, so that the user can obtain a better holding posture when using the cosmetic brush.

[0051] Furthermore, if Figure 1 and Figure 5 As shown, the pen cap 120 includes a leak-proof member 121 disposed inside the pen cap 120. When the pen cap 120 is connected to the pen head 110, the leak-proof member 121 abuts against the hole of the liquid outlet brush head 111. The leak-proof member 121 can block the liquid outlet hole of the liquid outlet brush head 111 to prevent liquid leakage during transportation.
