Description

Technical Field

[0001] This utility model relates to cosmetic products, specifically an eyebrow pencil with multiple types of tips. Background Technology

[0002] An eyebrow pencil is a pencil-shaped makeup tool used for drawing eyebrows. Existing eyebrow pencils are typically single-core, meaning they contain only a single lead. If multiple colors are needed for color makeup, this can be inconvenient to carry and use. To address this issue, a utility model entitled "A Novel Three-Color Eyeliner" was published in Chinese patent literature (CN208909210U, published on May 31, 2019). This model discloses a structure similar to existing three-color ballpoint pens, featuring three sliding knobs corresponding to the three colors of the lead. When needed, pressing one of the knobs pushes out the corresponding lead sleeve, and rotating the sleeve allows the lead to be used by a spiral pusher. While this structure allows for multi-color switching, the overall structure remains complex, requiring three sets of sliding knobs. Furthermore, the tip or nib of this type of eyeliner is a single structure, not adjustable or easily replaceable, which is inconvenient when different types of tips are needed. Therefore, improvements are needed to the structure of existing multi-color eyebrow pencils. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide an eyebrow pencil with multiple types of tips, thereby solving the technical problem that existing eyebrow pencils of the same type have complex structures and single-function tips, making it impossible to change the type of tip for use. This objective is achieved through the following technical solution.

[0004] An eyebrow pencil with multiple types of tips includes a pencil shell and a lead assembly. The pencil shell includes a tip, a body, and a top mount. The tip and top mount are fixed to both ends of the body. The tip has a tip outlet hole. The key structural feature is that the lead assembly includes a rotating support, a lead rod, a lead holder, and at least two different tip types. The rotating support is confined within the body and can rotate movably. The circumference of the rotating support is evenly arrayed with axially arranged lead rod grooves. Each lead rod groove contains an axially sliding, non-rotating lead rod. Each lead rod has an inner cavity and a threaded opening at one end. The lead holder has a clamping port at one end for clamping the lead, and a lead screw integrated at the other end. The lead screw engages with the threaded opening at the bottom of the lead rod and extends into the inner cavity of the lead rod. The lead holder slides within the through hole of the tip and rotates synchronously with the tip. The tip of the pen is inserted into the bottom of the core rod to form a relative rotation. When the pen tip rotates relative to the core rod, the core seat slides relative to the pen tip, that is, the core of the core seat extends or retracts relative to the pen tip. The outer side of the pen body has a sliding hole along the length of the pen body, and a sliding button that slides with the sliding hole. Near the two ends of the sliding hole, there are toothed ribs that elastically engage with the sides of the sliding button to prevent slippage. The end of the sliding button that extends into the inner hole of the pen body has an overlapping part. The top of the core rod has an overlapping groove that matches the overlapping part. When the core rod rotates with the core rod support, the overlapping groove of the core rod and the overlapping part of the sliding button alternately overlap and engage. After overlapping and engaging, the core rod slides with the sliding button. When the sliding button slides to engage with the toothed rib at the bottom of the sliding hole, the core rod pushes the pen tip out of the pen head. With the above structure, this eyebrow pencil does not need to have multiple sets of sliding buttons. By using a single sliding button in conjunction with the knob on the top of the pencil body, the lead can be switched and extended for use. It also has different types of pencil tips, allowing for quick and convenient switching as needed.

[0005] The top seat has an inner hole with a limiting flange on its inner wall. When the rotating core support drives the core rod to rotate, the overlapping groove of the core rod that is not engaged with the inner end of the sliding button engages with the limiting flange to form an axial limit. The inner hole is equipped with a rotating knob, and the operating part of the knob extends out of the top seat. The inner end of the knob is fixedly connected to the top of the rotating core support inside the pen body and rotates synchronously. This structure effectively limits the core rod inside the pen body, making its use more reliable and stable.

[0006] The pen tip has a protrusion on its side near the end, and the pen tip has a symmetrical groove at the end that guides the protrusion. With this structure, after the pen tip extends out of the pen tip and rotates into place, the pen tip is then controlled to extend into the pen tip so that the protrusion and groove limit the rotation, thus making the pen tip more reliable to use.

[0007] The tip type includes conical, double-slanted, and single-slanted tips. This structure is a common type of eyebrow pencil tip, but the tip is not limited to the shapes described above.

[0008] The outer surface of the pen refill holder is elliptical or polygonal. This structure allows the pen refill holder to slide relative to the pen refill while simultaneously rotating.

[0009] The slider has elastic latches on both sides that engage with the toothed ribs of the sliding hole. This structure allows the slider to lock in place when it slides into position relative to the sliding hole, preventing the slider, the core rod, and the pen refill from sliding easily, making it more reliable and convenient to use.

[0010] The rotating core support has a raised axial rib in the core rod groove, and the circumferential surface of the core rod has a groove that mates with the axial rib. This structure allows the core rod to slide axially relative to the core rod groove without relative rotation.

[0011] The pen tip has an annular groove at the through hole, and the end of the core rod that engages with the pen tip has an annular rib that mates with the annular groove. This structure enables quick connection and relative rotation between the pen tip and the core rod.

[0012] The pen tip and pen body are connected by a plug-in joint. The pen tip has a plug hole, and the pen body has a plug. The plug hole has an annular groove, and the plug has an annular rib that mates with the annular groove. The end face of the plug hole in the pen tip has a protruding positioning post, and the base of the plug in the pen body has a positioning hole that mates with the positioning post. When the positioning post mates with the positioning hole, the pen body and pen tip are prevented from rotating. The top of the pen body and the top seat are fitted with an interference fit. This structure enables quick connection and fixation between the pen body and the top seat, and quick connection and relative anti-rotation between the pen tip and the pen body.

[0013] The top of the rotating bracket forms a socket, and the inner end of the knob has a slot that fits into the socket with an interference fit. This structure enables quick connection and fixation between the knob and the rotating bracket.

[0014] The overall structure of this utility model is relatively compact and reasonable, with relatively few parts. It can switch between the required pen tip or lead as needed, making it convenient, quick, and reliable to operate. It has a wide range of applications and is suitable for use as a multi-functional eyebrow pencil in the field of makeup, or as an improvement on the structure of similar eyebrow pencils.

Implementation

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] like Figures 1-9As shown, this eyebrow pencil with multiple types of tips includes a pencil case and a refill assembly. The pencil case includes a tip 1, a body 2, and a top base 3. The tip has a tip outlet hole and an insertion hole 101 at the top. A protruding positioning post 102 is provided at the end face of the insertion hole, and an annular groove is provided inside the insertion hole. The bottom of the body has a plug 203 with an annular retaining rib that mates with the annular groove. The base of the plug has a positioning hole that mates with the positioning post, thus the tip is inserted and fixed to the bottom of the body. When the tip is not in use, a cap 11 can be sealed to the outside to achieve dust and water resistance. The top base is interference-fitted and fixed to the top opening of the body. The refill assembly includes a rotating refill bracket 6, a refill rod 7, a refill base 8, a refill 9, and three tips 10 with different end types: a conical tip, a double-angled tip, and a single-angled tip. The rotating core support is located between the bottom end and the top seat inside the pen body and is movably rotatable relative to the inner hole of the pen body. Three sets of axially arranged core rod grooves 601 are evenly arrayed on the circumference of the rotating core support. Each core rod groove contains a core rod 7 that slides axially without relative rotation; that is, the circumference of the core rod has a groove 701, and the core rod groove contains an axial rib 602 that mates with the groove. Each core rod has an inner cavity and a threaded opening 704 at its bottom end. One end of the pen refill holder has a clamping port for clamping and connecting the pen refill, and the other end integrates a lead screw 801. The lead screw mates with the threaded opening at the bottom of the core rod and extends into the inner cavity of the core rod. The outer circumferential surface of the aforementioned pen refill holder is elliptical. The pen tip's through-hole 1001 contains an elliptical segment that matches the elliptical outer circumferential surface of the pen refill holder. This fit allows the pen refill holder to slide axially relative to the pen tip's through-hole and rotate with the pen tip. Alternatively, the outer circumferential surface of the pen refill holder can also be polygonal, with a corresponding polygonal segment in the pen tip's through-hole, achieving the same purpose. The pen tip's tail end through-hole contains an annular groove, and the bottom of the core rod contains an annular rib 703 that mates with the annular groove. The bottom of the core rod and the tail end of the pen tip are inserted and fitted together, forming a relative rotation. When the pen tip rotates relative to the core rod, it drives the lead screw of the pen refill holder and the threaded opening of the core rod to form a transmission, thus causing the pen refill holder to slide relative to the pen tip, and the pen refill in the pen refill holder to extend or retract relative to the pen tip.

[0027] The outer side of the pen body 2 is provided with a sliding hole 201 along the length of the pen body, and a sliding button 5 that slides in conjunction with the sliding hole. Near both ends of the sliding hole, there are toothed ribs 202 that form an elastic engagement with the spring clips 502 on both sides of the sliding button to prevent slippage. One end of the sliding button that extends into the inner hole of the pen body is provided with an overlapping part 501, and the top of the core rod 7 is provided with an overlapping groove 702 that matches the overlapping part. When the core rod is located at the upper sliding limit end of the rotating core bracket and rotates with the rotating core bracket, the overlapping groove of the core rod and the overlapping part of the sliding button form an alternating overlapping engagement, and the core rod slides with the sliding button after the overlapping engagement; when the sliding button slides to engage with the toothed rib at the bottom end of the sliding hole, the core rod pushes the pen tip 10 to extend out of the pen head 1. The top seat 3 is provided with an inner hole, and the inner wall of the inner hole is provided with a limiting flange 301. When the rotating core bracket drives the core rod to rotate, the overlapping groove of the core rod that does not engage with the inner end of the sliding button engages with the limiting flange to form an axial limit. A rotating knob 4 is installed in the inner hole of the top seat, and the operating part of the knob extends out of the top seat. The inner end of the knob is provided with a slot, which is interference-fitted with the socket 603 on the top of the rotating core bracket 6 inside the pen body to form a fixed position, that is, the rotating core bracket rotates with the knob.

[0028] The eyebrow pencil is used as follows: In the initial state, each tip 10 is located inside the head 1, and the sliding button 5 is located at the top of the sliding hole 201 of the body 2. It is self-locking by the elastic buckles 502 on both sides of the sliding button and the toothed ribs 202 on both sides of the top of the sliding hole. When the corresponding pen tip 10 or pen refill 9 needs to be extended for use, first turn the knob 4 at the top of the pen body 3. The knob drives the rotating core bracket 6 to rotate until the overlapping groove 702 of the core rod 7 of the desired pen tip is engaged with the overlapping part 501 at the inner end of the sliding knob. Then slide the sliding knob to the bottom of the sliding hole. The sliding knob forms a self-locking mechanism by the elastic buckles on both sides and the toothed ribs on both sides of the bottom of the sliding hole. The corresponding pen tip then extends out of the pen head 1. Next, turn the pen tip that has extended out of the pen head. The pen tip drives the pen refill seat 8 to rotate synchronously. When the pen refill seat rotates, the screw 801 and the threaded opening 704 of the core rod form a transmission, driving the pen refill seat to slide towards the pen tip until the pen refill connected to the pen refill seat extends out of the pen tip. Finally, control the sliding knob to slide in the opposite direction for a certain distance, and let the protrusion 1002 on the side of the pen tip extend into the pen tip port and engage with the guide slot 103 on one side to form a positioning, restricting the rotation of the pen tip. Then, the pen refill that is currently extending out of the pen tip can be used for eyebrow drawing. After use, slide the slider to extend the pen tip back into place, rotate the pen tip in the opposite direction to retract the pen refill into the pen tip, and then slide the slider to the top of the sliding hole to complete the pen tip retraction and reset.

[0029] The above description is intended to illustrate the technical means of this utility model and is not intended to limit the technical scope of this utility model. Any obvious improvements or substitutions made to this utility model by those skilled in the art based on existing common knowledge also fall within the protection scope of the claims of this utility model.
