DETAILED DESCRIPTION

[0060] The embodiment of the utility model discloses a cosmetic pen with an elastic component, which solves the technical problem that the refill of the existing automatic cosmetic pen is easy to break during transportation, falling and use.

[0061] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0062] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0063] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0064] See also Figures 1 to 17, the embodiment of the utility model provides a cosmetic pen with an elastic component, comprising: a pen tube 1 and an elastic support cup spiral component 2;

[0065] The elastic cup spiral assembly 2 is arranged in the pen tube 1, and comprises a cup 21, an elastic body 22 and a spiral rod 23;

[0066] The spiral rod 23 is provided with an external threaded portion 231 adapted to the internal threaded portion 121 in the pen tube 1, and a positioning groove 232 is provided at the upper end of the spiral rod 23;

[0067] A positioning block 211 is disposed at the lower end of the support cup 21, and the positioning block 211 is slidably connected to the positioning groove 232 along the axial direction of the pen tube 1;

[0068] The elastic body 22 is disposed between the lower end of the positioning block 211 and the bottom of the positioning groove 232 .

[0069] It should be noted that the support cup 21 and the spiral rod 23 cannot rotate relative to each other; when the support cup 21 is subjected to axial pressure, the positioning block 211 slides to the bottom of the positioning groove 232, and the elastic body 22 is compressed; when the support cup 21 is not subjected to axial external force, the elastic body 22 is in a balanced state or a compressed state, and the size of the elastic body 22 allows the positioning block 211 to be located at the highest position it can slide to in the positioning groove 232, so that the support cup 21 has no extra space in the positioning groove 232 for axial shaking; the elastic body 22 can be a spring or a soft colloid with a hardness of 30° to 50°, such as TPE, silicone, NBR, etc.; this embodiment provides The cosmetic brush also includes a refill 4, the lower end of which is arranged in the cup portion of the support cup 21. When the pen tip portion of the pen tube 1 is rotated relative to the portion of the pen tube 1 where the internal thread portion 121 is provided, the refill 4 can rise from the pen tube 1 and be exposed from the pen tip portion, or fall down to be completely hidden in the pen tube 1. The arrangement of the positioning groove 232, the elastic body 22 and the positioning block 211 allows the support cup 21 to have a certain buffer space in the axial direction. When the refill 4 is subjected to axial pressure, it can slightly retract into the pen tube, so that the refill is not easy to break during transportation, falling and use, and can improve the touch of the refill contacting the skin when the user uses it, effectively improving the user experience in many aspects.

[0070] Specifically, the pen tube 1 includes a nib tube 11 and a spiral tube 12. The upper end of the spiral tube 12 is coaxially rotatably sleeved on the outside of the lower end of the nib tube 11. An internal threaded portion 121 is provided inside the spiral tube 12. A limiting structure is provided inside the nib tube 11 to limit the circumferential rotation of the elastic support cup spiral assembly 2 along the pen tube 1. When the spiral tube 12 and the nib tube 11 rotate relative to each other, the limiting structure inside the nib tube 11 prevents the elastic support cup spiral assembly 2 from rotating with the spiral tube 12, and the internal threaded portion 121 and the external threaded portion 231 enable the elastic support cup spiral assembly 2 to move axially along the pen tube 1; the limiting structure inside the nib tube 11 can be used to limit the support cup 21 or to limit the pen core 4.

[0071] In a preferred embodiment, in order to allow the user to choose whether the refill needs to be elastic during use, the cosmetic pen provided by the utility model further includes a friction adjustment claw 3;

[0072] The lower portion 31 of the friction adjustment claw 3 is annular, and the lower portion 31 is arranged between the spiral tube 12 and the support cup 21;

[0073] A plurality of clamping claws 32 are provided on the upper part of the friction adjustment claw 3, and the ends of the clamping claws 32 are inclined to extend between the pen tip tube 11 and the support cup 21;

[0074] The outer diameter of the lower portion 31 is greater than the inner diameter of the pen tip tube 11, so that the pen tip tube 11 can squeeze the outer side surface of the clamping claw 32 after moving downward;

[0075] The spiral tube 12 and the pen tip tube 11 are provided with a snap-fit ​​structure;

[0076] When the clamping structure is in the first clamping state, the lower end of the nib tube 11 presses the outer side surfaces of the plurality of clamping claws 32, and the ends of the plurality of clamping claws 32 clamp the support cup 21;

[0077] When the engaging structure is in the second engaging state, the lower end of the nib tube 11 is not in contact with the outer side surfaces of the plurality of clamping claws 32 .

[0078] Specifically, the engaging structure includes a convex ring 122 disposed on the inner wall of the spiral tube 12 and a first concave ring 111 and a second concave ring 112 sequentially opened on the outer wall of the nib tube 11;

[0079] When the convex ring 122 is engaged with the first concave ring 111 , the lower end of the nib tube 11 presses the outer side surfaces of the plurality of clamping claws 32 , and the ends of the plurality of clamping claws 32 clamp the support cup 21 ;

[0080] When the convex ring 122 is engaged with the second concave ring 112 , the lower end of the nib tube 11 is not in contact with the outer side surfaces of the plurality of clamping claws 32 .

[0081] It is understandable that the elasticity of the refill 4 may affect the makeup feel of some users. In the process of using the makeup brush provided by this embodiment, when the user does not need the refill 4 to have elasticity, the pen tip tube 11 can be pushed to make it move axially relative to the spiral tube 12, so that the convex ring 122 is engaged with the first concave ring 111. At this time, the lower end of the pen tip tube 11 squeezes the outer side surfaces of the multiple clamping claws 32, and the clamping claws 32 are deformed, and the ends are tightly attached to the outer surface of the support cup 21. The ends of the multiple clamping claws 32 clamp the support cup 21 together, so that the support cup 21 is subjected to the axial force and is also subjected to the The axial friction force from the clamping jaws 32 will not make it move easily, and it is difficult to make the nib tube 11 and the spiral tube 12 rotate relative to each other at this time, which can facilitate the user to fine-tune the lifting height of the pen core 4; when the user needs the pen core 4 to be elastic, the nib tube 11 can be pulled to make it move axially relative to the spiral tube 12, so that the convex ring 122 is engaged with the second concave ring 112. At this time, the lower end of the nib tube 11 has no contact with the outer side surfaces of the multiple clamping jaws 32. The pen core 4 can move slightly when subjected to axial pressure, and the nib tube 11 or the spiral tube 12 can be rotated normally to raise or lower the pen core 4.

[0082] The material of the clamping jaws 32 is preferably soft rubber, such as TPE, silicone, NBR, etc., and the number of the clamping jaws 32 is preferably 2, 3 or 4; further, the inner wall of the lower end of the nib tube 11 can be provided with a slope 113 to reduce the local pressure of the lower end of the nib tube 11 on the clamping jaws 32 and extend the service life of the friction adjustment claw 3.

[0083] In a preferred embodiment, the cross section of the pen core 4 is polygonal, preferably triangular, and the upper end face of the pen core 4 is preferably an inclined surface. The polygonal cross section and the inclined upper end face make the tip of the pen core 4 have more sharp edges, which is convenient for users to draw lines.

[0084] Furthermore, a limiting structure 114 is provided inside the nib tube 11 , which is protruding inward and matches the cross-sectional shape of the pen core 4 , and can limit the rotation of the elastic support cup spiral assembly 2 as a whole along the circumferential direction of the pen tube 1 .

[0085] In order to limit the relative rotation of the support cup 21 and the spiral rod 23 and limit the relative sliding distance between the support cup 21 and the spiral rod 23, in a preferred embodiment, the edge of the end of the positioning block 211 is provided with a first undercut structure 2111 protruding radially outward along the positioning block 211, and the notch of the positioning groove 232 is provided with a second undercut structure 2321 protruding into the groove, and the cross section of the first undercut structure 2111 is adapted to the shape and size of the cross section of the positioning groove body 2322;

[0086] The cross section of the second undercut structure 2321 matches the shape and size of the cross section of the positioning block body 2112;

[0087] The cross section of the positioning block body 2112 and / or the positioning groove body 2322 is polygonal, preferably square.

[0088] In a specific embodiment, in order to beautify and protect the internal components of the cosmetic brush, the cosmetic brush provided by the utility model further includes a pen holder 5 and a pen cover 6;

[0089] The pen holder 5 is fixedly sleeved outside the spiral tube 12, and the pen cap 6 is covered outside the pen tip tube 11. More specifically, the lower end of the pen cap 6 can be engaged with the upper end of the spiral tube 12;

[0090] In order to facilitate the processing of makeup details, the end of the makeup pen provided by the utility model away from the pen tip can also be provided with a makeup brush, such as an eyebrow brush 7 and a corresponding eyebrow brush cover 8 can be provided at the end of the makeup pen away from the pen tip.

[0091] The above is a detailed introduction to a cosmetic brush with an elastic component provided by the present invention. For a person skilled in the art, according to the idea of ​​the embodiments of the present invention, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
