[0034] In one embodiment of the present invention, referring to Figure 1-Figure 6 , provides a ball-tip push-type automatic cosmetic pen, including a pen shell 100 and a pen head 150 arranged at one end of the pen shell 100.

[0035] Among them, refer to Figure 1-Figure 3 The pen housing 100 is provided with a liquid storage chamber 110 for storing cosmetic liquid. The pen head 150 is provided with a brush head 160 , and the brush head 160 is provided with a liquid storage channel 161 communicating with the liquid storage chamber 110 .

[0036] Among them, refer to Figure 1-Figure 3 The ball-tip push-type automatic cosmetic pen further includes a pen cap 200 , and a sealing member 210 is disposed inside the pen cap 200 . When the pen cap 200 is connected to the pen head 150 , the sealing member 210 seals the liquid storage channel 161 .

[0037] Compared with the prior art, the above one or more technical solutions in the ball-head pressing automatic cosmetic brush provided by the embodiment of the utility model have at least one of the following technical effects:

[0038] Reference Figure 1-Figure 3 When in use, the user removes the pen cap 200 from the pen head 150, and the lip glaze makeup liquid in the liquid storage chamber 110 is transported to the brush head 160 along the liquid storage channel 161, so that the brush head 160 contains the lip glaze makeup liquid. The user can use the brush head 160 to apply the lip glaze makeup liquid to the lips. It is easy to use and has extremely high practicality. There is no need to dip the lip glaze makeup liquid in the bottle every time you use it.

[0039] Reference Figure 1-Figure 3 The pen cap 200 is covered on the pen tip 150 so that the seal 210 seals the liquid storage channel 161. When not in use or in transportation, the lip gloss makeup liquid in the liquid storage cavity 110 and the liquid storage channel 161 will not flow out from the outlet of the liquid storage channel 161, thereby preventing leakage and maintaining a stable structure.

[0040] Further, refer to Figure 1 and Figure 2 The sealing member 210 is a sealing column, and the diameter of the sealing column decreases from the end close to the brush head 160 to the end away from the brush head 160, so that the brush head 160 is tapered. The sealing column is used to be sealed and inserted into the liquid storage channel 161. Specifically, the diameter of the small end of the sealing column is smaller than the diameter of the liquid storage channel 161, and the diameter of the large end of the sealing column is larger than the diameter of the liquid storage channel 161. Therefore, the small end of the sealing column is conducive to inserting into the liquid storage channel 161, and the large end of the sealing column is used to seal and block the liquid storage channel 161.

[0041] Further, refer to Figure 1 and Figure 2The top of the pen cap 200 is provided with a mounting groove 201, and one end of the sealing column is provided with a mounting seat 211, which is fixedly installed in the mounting groove 201 for easy installation. The mounting seat 211 is provided with a cavity 212, so that the mounting seat 211 can be squeezed, so that the mounting seat 211 can be conveniently installed in the mounting groove 201 during installation.

[0042] Further, refer to Figure 1 and Figure 2 The brush head 160 is a spherical flocking head, which is convenient for the user to apply lip glaze makeup liquid to the lips, which is conducive to makeup.

[0043] In another embodiment of the present invention, referring to Figure 1 and Figure 2 A connecting ring 120 is provided at one end of the pen housing 100, and an inner ring 151 and an outer ring 155 are provided at the end of the pen head 150 away from the brush head 160. The outer ring 155 is sealed and sleeved outside the connecting ring 120, and the inner ring 151 is sealed and plugged into the connecting ring 120, which plays a double sealing role to prevent the lip gloss makeup liquid in the liquid storage cavity 110 from overflowing from the gap between the pen housing 100 and the pen head 150, and the structure is reliable.

[0044] Further, refer to Figure 1 and Figure 2 One of the inner wall of the outer ring 155 and the outer wall of the connecting ring 120 is provided with a first sealing groove 156 along the circumferential direction, and the other is provided with a first sealing portion 121 along the circumferential direction. The first sealing portion 121 is sealed and connected to the first sealing groove 156, and the sealing effect is good, which prevents the lip gloss makeup liquid in the liquid storage cavity 110 from overflowing. One of the inner wall of the connecting ring 120 and the outer wall of the inner ring 151 is provided with a second sealing portion 122 along the circumferential direction, and the other is provided with a second sealing groove 152 along the circumferential direction. The second sealing portion 122 is sealed and connected to the second sealing groove 152, and the sealing effect is good, which prevents the lip gloss makeup liquid in the liquid storage cavity 110 from overflowing.

[0045] In another embodiment of the present invention, referring to Figure 1 , Figure 4 , Figure 5 and Figure 6 The ball-head pressing automatic cosmetic pen also includes a pressing structure 300 arranged at the other end of the pen shell.

[0046] The pressing structure 300 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.

[0047] Specifically, refer to Figure 1 , Figure 4, Figure 5 and Figure 6 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 part 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.

[0048] Further, refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The pressing structure also 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 .

[0049] 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.

[0050] Further, refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The position limiting base 350 is provided with a rotating tooth 351, and the position 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 position limiting tooth 332. The feeding tooth 331 is meshed with the rotating tooth 351, and the position 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 position limiting tooth 332 is meshed with the anti-backward tooth 361, the sleeve part 330 is prevented from rotating.

[0051] 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.

[0052] Further, refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 A reset elastic member 380 is disposed 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 .

[0053] 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.

[0054] Further, refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The sleeve portion 330 passes through the limiting top seat 360 and is sleeved with a pressing cover 370 . The pressing cover 370 pushes the sleeve portion 330 downward to abut against the limiting base 350 .

[0055] 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.

[0056] Further, refer to Figure 1 , Figure 4 , Figure 5 and Figure 6A 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 .

[0057] 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 .

[0058] Further, refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 , 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 to 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.

[0059] The rest of this embodiment is the same as the first embodiment. The features not explained in this embodiment are all based on the explanations in the first embodiment and will not be described in detail here.

[0060] The above content is a further detailed description of the utility model in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, its architecture can be flexible and can derive a series of products. Just making a few simple deductions or substitutions should be regarded as belonging to the patent protection scope of the utility model determined by the submitted claims.
