Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cosmetics, in particular to a cosmetic brush with a smooth rotation and damping feeling. Background Art
[0002] Eyebrow pencil is a cosmetic product for drawing eyebrows. Modern eyebrow pencils come in two forms, one is a pencil type and the other is a push tube type, and when used, the pencil core is pushed out to draw eyebrows.
[0003] The prior art push-tube eyebrow pencil drives the internal screw to push the pencil core out of the pen holder by rotating the rotating member relative to the pen holder. In order to make the rotation smooth, a rubber ring is arranged between the pen holder and the rotating member. However, during the manufacturing process, it requires a certain degree of precision and skill to install the rubber ring into the rubber ring groove. If it is not installed properly, it will affect the use and rotation of the eyebrow pencil and even cause damage to the rubber ring. Moreover, as the eyebrow pencil is used and rotated, the rubber ring will gradually wear due to friction with the rotating member and the pen holder, making the rotation not smooth enough, with a sense of frustration and poor rotation feel. Utility Model Content
[0004] Based on this, in order to solve the above problems, the utility model provides a cosmetic brush with a smooth rotation and damping feeling.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] A cosmetic pen with a smooth rotation and damping feeling, comprising a pen holder, a rotating member and a pen core, wherein the pen holder is buckled on the rotating member, the rotating member has a accommodating cavity, the pen holder has a pen core cavity communicating with the accommodating cavity, the upper end of the pen core cavity is provided with an outlet communicating with the outside, a propulsion structure is provided in the accommodating cavity, the propulsion structure is connected with the pen core and drives the upper end of the pen core to extend out of the pen core cavity from the outlet, a convex ring is provided on the outer circumferential surface of the rotating member, the rotating member is divided into an insertion part and a rotating part, the pen holder is buckled on the insertion part of the rotating member and its end face contacts the front end face of the convex ring and is stopped and limited by the convex ring, an elastic member connected to the convex ring is provided at the root of the insertion part, and a convex head which always contacts the inner wall of the pen holder is provided on the elastic member.
[0007] By adopting the above technical solution, the elastic member is provided to make the rotating member rotate more smoothly relative to the pen holder. Compared with the rubber ring method used in the prior art, the elastic member can adapt to the slight difference between the pen holder and the rotating member of different sizes or shapes, ensuring a good rotation effect. However, the rubber ring may be limited by size matching, and once the size is slightly deviated, the rotation effect may be affected.
[0008] In a specific embodiment of the utility model, a pair of notches are symmetrically arranged at the root of the insertion part of the rotating member, and the number of the elastic members is two, which are respectively arranged in the corresponding notches. Each elastic member includes a vertically arranged spring sheet and a convex head fixed on the upper part of the outer side surface of the spring sheet. One end of the spring sheet is connected to the wall of the convex ring, and the other end is a free end. The outer end surface of the convex head abuts against the inner wall of the pen holder. With the above technical solution, in the initial state, the outer end surface of the convex head slightly protrudes outward from the circumferential surface of the insertion part. When the insertion part is fully inserted into the interior of the pen holder, the inner wall of the pen holder will squeeze the spring sheet, causing the spring sheet to bend inward and generate elastic force, so that the convex head always abuts against the inner wall of the pen holder. In this way, when rotating the rotating member, it is smoother and has a damping feeling. In addition, the spring sheet is used to replace the rubber ring of the prior art, which is not easy to wear. Even if it is used for a long time, the smoothness and damping feeling will not be reduced, and the user experience will not be reduced.
[0009] In a specific embodiment of the utility model, a ring-shaped convex ring is provided on the periphery of the insertion portion of the rotating member, and an annular groove matching the convex ring is provided on the inner wall of the pen holder. With the above technical solution, the convex ring is inserted into the annular groove, so that the rotating member and the pen holder are not easy to fall off and the rotating member is not hindered from rotating relative to the pen holder.
[0010] In a specific implementation of the utility model, the propulsion structure includes a screw rod disposed in the accommodating cavity, and an internal thread meshing with the screw rod is provided on the inner wall of the accommodating cavity.
[0011] In a specific implementation of the utility model, the front end of the screw rod has a rotation-stopping portion, and a slot is vertically provided on the inner wall of the pen core cavity, and the rotation-stopping portion is inserted into the slot.
[0012] In a specific implementation of the utility model, a stop step is provided at the upper end of the card slot in the refill cavity. With the above technical solution, the stop step can stop and limit the anti-rotation part.
[0013] In a specific implementation manner of the utility model, the front end of the anti-rotation portion has a refill fixing portion for fixing the refill.
[0014] In a specific implementation of the utility model, the refill fixing portion includes clamping plates arranged opposite to each other, a fixing cavity is formed between the two clamping plates, and the refill is clamped in the fixing cavity.
[0015] In a specific implementation manner of the utility model, an exhaust hole is opened at the bottom of the rotating member.
[0016] In summary, the cosmetic pen with smooth rotation and damping of the utility model uses an elastic sheet to replace the rubber ring of the prior art, so that the rotation between the pen holder and the rotating part of the eyebrow pencil is smoother and has a damping feeling, and is not easy to wear, thereby improving the user experience of the product.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.
[0024] See also Figure 1 As shown, the utility model is a cosmetic pen with a smooth rotation damping feeling, comprising a pen holder 10, a rotating member 20 and a pen core (not shown in the figure). The pen holder 10 is divided into a pen head 101 and a rod body 102.
[0025] The rotating member 20 is connected to the pen holder 10 and can rotate relative to the pen holder 10. The rotating member 20 has a receiving chamber 21. The pen holder 10 has a core chamber 11 in communication with the receiving chamber 21. An outlet 12 in communication with the outside is provided at the upper end of the core chamber 11.
[0026] The core cavity 11 of the pen holder 10 is divided into a first section 111, a second section 112, and a third section 113 from top to bottom. The diameter of the second section 112 is larger than that of the first section 111, so that a stop step 114 is formed at the junction of the second section 112 and the first section 111.
[0027] A propulsion structure is provided in the accommodating chamber 21 . The propulsion structure is connected to the pen core and drives the pen core to extend out of the pen core chamber 11 through the outlet 12 .
[0028] The propulsion structure includes a screw rod 23 disposed in the accommodating chamber 21. An internal thread engaged with the screw rod 23 is provided on the upper portion of the inner wall of the accommodating chamber 21.
[0029] like Figure 1 , Figure 4 and Figure 5 As shown, the front end of the screw rod 23 has a stopper 231. A slot 115 extending in the axial direction is provided on the left and right sides of the inner wall of the second section 112. The upper end of the slot 115 extends to the stop step 114. In this way, the stopper 231 is assembled in the second section 112, and the protruding parts on the left and right sides of the stopper 231 are respectively inserted into the corresponding slots 115, so that the screw rod 23 can only move axially along the second section 112, but cannot rotate in the pen holder 10. At the same time, the stop step 114 can stop and limit the stopper.
[0030] like Figure 1 and Figure 4 As shown, a refill fixing part for fixing the refill is provided at the front end of the rotation-stopping part 231. The refill fixing part includes clamping plates 30 fixed on the rotation-stopping part and arranged opposite to each other. A fixing cavity is formed between the two clamping plates 30, and the refill is clamped in the fixing cavity.
[0031] In this way, the rotating member 20 rotates relative to the pen shaft 10 , which can push the screw 23 to move axially, thereby pushing the pen core to emerge from the pen shaft 10 or retract into the pen shaft 10 .
[0032] like Figure 1 and Figure 2 As shown, a convex ring 24 is provided on the outer circumferential surface of the rotating member 20, dividing the rotating member 20 into an insertion portion 25 inserted into the core cavity 11 and a rotating portion 26 located outside the core cavity 11. The length of the rotating portion 26 accounts for about 1 / 8 of the length of the entire cosmetic pen. The pen holder 10 is buckled on the insertion portion 25 of the rotating member 20 and its rear end surface contacts the front end surface of the convex ring 24, and is stopped and limited by the convex ring 24.
[0033] like Figure 1 , Figure 2 and Figure 3 As shown, an elastic member 40 is provided at the root of the insertion portion 25 .
[0034] A pair of notches 251 are symmetrically arranged at the root of the insertion part 25 of the rotating member 20. There are two elastic members 40, which are respectively located in the corresponding notches 251. Each elastic member 40 includes a vertically arranged spring sheet 41 and a protruding head 42 fixed on the upper part of the outer side of the spring sheet and protruding outward. One end of the spring sheet 41 is connected to the wall of the protruding ring 24, and the other end is a free end. The outer end surface of the protruding head 42 is a spherical surface. In the initial state, the outer end surface of the protruding head 42 slightly protrudes outward from the circumferential surface of the insertion part 25. When the insertion part 25 is fully inserted into the interior of the pen body 10, the inner wall of the pen body 10 will squeeze the spring sheet 41, so that the spring sheet 41 bends inward and generates elastic force, so that the protruding head 44 always contacts the inner wall of the pen body 10. In this way, when the rotating member 20 is rotated, it is smoother and has a damping feeling, and the spring sheet is used to replace the rubber ring of the prior art, which is not easy to wear, and even if it is used for a long time, the smoothness and damping feeling will not be reduced, and the user experience will not be reduced.
[0035] like Figure 1 and Figure 2 As shown, in addition, a ring-shaped convex ring 27 is provided around the insertion portion of the rotating member 20. An annular groove 28 matching the convex ring 27 is provided on the inner wall of the pen holder 10. In this way, the convex ring 27 is inserted into the annular groove 28, so that the rotating member 20 and the pen holder 10 are not easy to fall off and the rotating member 20 is not hindered from rotating relative to the pen holder 10.
[0036] like Figure 1 As shown, an exhaust hole 201 is provided at the bottom of the rotating member 20. By adding the exhaust hole 201, when the screw 23 rotates and retreats, the gas in the accommodating chamber 21 can be quickly discharged from the exhaust hole 201, thereby reducing the resistance of the screw 23 rotating and retreating, and improving the user experience.
[0037] In summary, the cosmetic pen with smooth rotation and damping of the utility model uses an elastic sheet to replace the rubber ring of the prior art, so that the rotation between the pen holder and the rotating part of the eyebrow pencil is smoother and has a damping feeling, and is not easy to wear, thereby improving the user experience of the product.
[0038] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
