Description

Technical Field

[0001] The utility model relates to the field of cosmetics, in particular to a cosmetic pen suitable for a thin pen core. Background Art

[0002] The refills of existing rotary cosmetic brushes are mostly cylindrical in shape, which is relatively difficult to control when drawing fine lines or applying details. To meet customer needs, the refills are cleverly designed into a flat and slender rod. Users can flexibly adjust the thickness and angle of the brushstrokes. The narrow side can draw delicate lines, while the wide side can quickly fill in larger areas. However, the thin refills currently on the market are usually around 1.2 mm thick, which cannot meet the needs of some makeup applications that require precise operation, such as drawing eyebrows or eyeliner. In addition, due to its narrow cross-section and relatively long length, this structure also brings a certain degree of fragility. In actual use, especially when applying pressure to outline or fill in eyebrows, the refill may easily break due to the force. Utility Model Content

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 、 Figure 4 and Figure 6 As shown, the present invention is a cosmetic brush suitable for thin refills, comprising a pen holder 10, a rotating member 20, and a refill 30. The rotating member 20 is mounted at the rear end of the pen holder 10 and is rotatable relative to the pen holder 10. The pen holder 10 and the rotating member 20 define a cavity. An outlet 12 communicating with the outside world is provided at the top of the cavity. This outlet 12 is a flat opening adapted to the cross-section of the refill. A push rod 24 is located within the cavity. This push rod 24 is connected to the refill 30 and, when rotated, drives the upper end of the refill 30 out of the pen holder through the outlet 12. In this embodiment, the refill 30 is a flat, elongated rod.

[0027] In this embodiment, the thickness of the pen core is 0.6mm to 0.8mm, which is very thin and light, and can better meet the needs of users when drawing eyebrows or eyeliner and needing to draw fine lines or perform detail processing.

[0028] Combine Figure 5As shown, the interior of the pen holder 10 is divided, from top to bottom, into an outlet section 111, a travel section 112, and an insertion section 113. The outlet section 111 is a flat channel adapted to the shape of the refill 30, guiding and supporting the refill. The travel section 112 is a channel adapted to the shape of the refill holder of the push rod, allowing axial movement within the travel section 112. A stop step 114 is formed at the junction of the travel section 112 and the outlet section 111.

[0029] A raised ring 29 is provided on the outer circumference of the rotating member 20, dividing the rotating member 20 into an insertion portion 22 and a rotating portion 23. The insertion portion 22 is inserted into the insertion section 113 of the pen holder 10. When the pen holder 10 is engaged with the insertion portion 22 of the rotating member 20, its rear end abuts against the front end of the raised ring 29, where it is stopped and retained.

[0030] In this embodiment, the push rod 24 includes a screw portion 25 and a refill securing portion 26 located at the front end of the screw portion 25. An internal thread that engages with the screw portion 25 is provided on the upper inner wall of the rotating member 20. The refill securing portion 26 defines a securing cavity 261. The tail end of the refill 30 is inserted into this securing cavity 261. Thus, rotation of the rotating member 20 relative to the pen barrel 10 drives axial movement of the push rod 24, thereby pushing the refill 30 out of or into the pen barrel 10.

[0031] like Figure 2 、 Figure 3 and Figure 5 As shown, ridges 115 are provided on the inner wall of the stroke section 112, located on either side of the lead's thickness, for guiding and supporting the lead. The upper ends of the ridges 115 extend to stop steps 114. The ridges 115 are arc-shaped. The gap between the two ridges 115 is slightly larger than the thickness of the lead 30. The stop steps 114 serve to stop and limit the lead's fixing portion 26.

[0032] In addition, a notch (not shown) for avoiding the ridge 115 is provided on the circumference of the lead fixing portion 26 at a position corresponding to the ridge 115. This structure can avoid the ridge from hindering the upward movement of the push rod.

[0033] In addition, in this embodiment, the cross-section of the stroke section 112 is rectangular. The cross-section of the refill fixing portion 26 is also rectangular. This structure allows the push rod to move only axially within the pen barrel, but not to rotate.

[0034] like Figure 4As shown, an annular bead 221 is provided around the rear of the insert 22. An annular groove 222 is provided on the inner wall of the pen barrel 10 to mate with the bead 221. With this solution, the bead 221 fits within the groove 222, preventing the rotating member 20 from falling out of the pen barrel 10 and preventing the rotating member 20 from rotating relative to the pen barrel. A sealing ring 27 is provided between the rear of the pen barrel 20 and the rear of the insert 22.

[0035] In addition, an exhaust hole 28 is provided at the bottom of the cavity. With the above technical solution, by adding the exhaust hole, the gas in the cavity can be quickly discharged from the exhaust hole when the push rod rotates back, thereby reducing the resistance of the push rod rotating back and improving the user experience.

[0036] To sum up, in the present invention, ridges are respectively provided on both sides of the inner wall of the pen barrel in the thickness direction of the pen core. The gap between the two ridges is slightly larger than the thickness of the pen core. The ridges can guide and support the pen core, preventing the pen core from bending and breaking under stress.

[0037] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
