Description

Technical Field

[0001] This utility model relates to the field of pencil sharpener technology, and more specifically, to a double-hole pencil sharpener structure for eyebrow pencils. Background Technology

[0002] In the beauty industry, eyebrow pencils are commonly used tools for outlining and filling in eyebrow color. They typically consist of an outer pencil and an inner wax or powder lead. When using them, one end of the lead needs to be sharpened to a fine point to ensure precision in eyebrow shaping. Previously, sharpening eyebrow pencils mainly relied on using a regular knife or craft knife. This method was fraught with risks: high operational danger (sharp blades can easily cut fingers, especially without professional skills, posing a significant safety hazard), difficulty in control (manual sharpening makes it hard to guarantee the uniformity, angle, and length of the tip, easily leading to lead breakage, or being too blunt or too sharp, making it impossible to create ideal, fine lines), significant waste (poor manual control can lead to a large amount of valuable lead being unnecessarily sharpened, shortening the product's lifespan and causing waste), and low efficiency (it only achieves a basic sharp tip effect; to achieve more detailed lines, further sharpening is required). The limitations of traditional pencils (such as the inability to modify and sharpen the tip to meet the demands of quick makeup application in today's fast-paced lifestyle) led to the development of pencil sharpeners. These sharpeners typically include a blade with a cavity and a cutting hole adapted to the diameter of the eyebrow pencil. A sharp metal blade is fixed inside the cutting hole. To use, one end of the eyebrow pencil is inserted into the cutting hole, and by manually rotating the pencil, the lead and the pencil barrel are gradually sharpened into the desired fine tip by the cutting action of the blade to meet the needs of subsequent makeup application. These sharpeners are widely used in eyebrow pencil products and are commonly available in manual and electric versions, conveniently meeting the needs of sharpening eyebrow pencils.

[0003] However, a single type of pencil sharpener, based on the shape of its single groove, can only cut one type of pencil lead shape. Therefore, it can only meet the basic need of sharpening the pencil tip and cannot satisfy consumers' demand for multiple shapes of eyebrow pencil leads. In summary, current technology, whether using a pencil sharpener or a knife / craft knife, cannot fully meet users' diverse needs for eyebrow pencil leads, nor can it achieve this goal simply and quickly. To achieve such an effect, users need to first sharpen the pencil with a pencil sharpener / craft knife, and then use a third-party tool to fix the pencil in the groove before using a knife to shape the tip. This operation is complex and cannot meet consumers' needs for quick use.

[0004] In summary, to meet consumers' demand for diverse eyebrow pencil lead shapes and quick usage scenarios, it is necessary to address the problems of existing pencil sharpeners that can only cut one type of lead shape with a single groove, the inconvenience of using small knives / utility knives, and the need for users to use additional third-party tools to achieve diverse eyebrow pencil lead shapes, which is complex. The goal is to enable users to easily and quickly obtain eyebrow pencil leads of various shapes without relying on additional tools, fully adapting to diverse eyebrow makeup needs. Utility Model Content

[0005] The present invention provides a double-hole pencil sharpener structure for eyebrow pencils, which aims to solve the following problems: existing pencil sharpeners with a single groove can only cut one type of pencil lead shape, are inconvenient to operate with a knife / utility knife, and require users to use additional third-party tools to achieve various shapes of eyebrow pencil leads, resulting in complex operation.

[0026] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Refer to the instruction manual appendix Figures 1 to 9 A double-hole pencil sharpener structure for eyebrow pencils includes a housing 1, an upper cover 2 connected to the housing 1, a large blade holder 3 installed inside the housing 1, a small blade holder 4 installed inside the upper cover 2, a circular slot 5 penetrating inside the large blade holder 3, a cutting groove 6 opened outside the large blade holder 3 and communicating with the circular slot 5, a sliding frame 8 slidably disposed outside the large blade holder 3, a pushing mechanism mounted on the housing 1, a large blade 10 mounted on the sliding frame 8, a circular slot 7 opened on the small blade holder 4, a through hole 11 opened on the surface of the upper cover 2 and communicating with the circular slot 7, and a small blade 12 mounted on the small blade holder 4. The output end of the pushing mechanism is connected to the sliding frame 8, and the pushing mechanism is used to drive the sliding frame 8 to move along a preset trajectory.

[0028] It should be noted that the cutting process for the eyebrow pencil mainly involves two steps. First, the eyebrow pencil is inserted through the through-hole 11 into the circular slot 7 within the small blade holder 4. After rotation, the small blade 12 cuts the outer surface of the pencil barrel, exposing the inner lead. The pencil is then pulled out and inserted into the large blade holder 3 from the other side through the circular slot 5, with the lead exposed outside the cutting groove 6. A pushing mechanism moves the sliding frame 8 along a preset trajectory on the outer surface of the large blade holder 3, pushing the installed large blade 10 to cut the lead exposed outside the cutting groove 6. The cutting process, which shapes the eyebrow pencil, can be divided into three main types: The first type involves the initial cutting after inserting the pencil, which shapes the pencil lead into a semi-circular shape, and then removes it. The second type involves removing the semi-circular pencil lead, using a pushing mechanism to push the sliding frame 8 and the large blade 10 back to their original positions, rotating the pencil lead 90 degrees before inserting it again, and then cutting it once more to form a triangular shape. The third type involves removing the semi-circular pencil lead after the first cutting, pushing the sliding frame 8 and the large blade 10 back to their original positions, rotating the pencil lead 180 degrees before re-inserting it, and then cutting it again to form a duckbill shape.

[0029] Refer to the instruction manual appendix Figure 2 The outer shell 1 is composed of a hollow cone and a semi-circular spherical shell. The upper cover 2 is a semi-circular spherical shell that fits and is installed with the semi-circular spherical shell on the outer shell 1. The large knife holder 3 is composed of a disc and half a cone that fits and is installed with the inner side of the outer shell 1.

[0030] It should be noted that the special shapes of the outer shell 1, the top cover 2, and the large blade holder 3 are adapted to each other for flexible assembly and disassembly, while also being able to perform the cutting task of the eyebrow pencil very well.

[0031] Refer to the instruction manual appendix Figure 2 A threaded ring 21 is fixedly connected inside one side of the top cover 2, and a threaded groove 22 adapted for threaded connection is opened in the semi-circular spherical shell on the outer shell 1.

[0032] It should be noted that the engagement of the threaded ring 21 and the threaded groove 22 allows for the disassembly and assembly of the outer shell 1 and the upper cover 2. When a large amount of cutting debris is stored in the small tool holder 4 inside the upper cover 2, it can be easily removed to empty and clean the debris.

[0033] Refer to the instruction manual appendix Figure 7 The driving mechanism includes a plug tube 901 fixedly connected to the sliding frame 8, a plug rod 902 inserted into the plug tube 901, and a lever ball 903 fixedly connected to one end of the plug rod 902.

[0034] It should be noted that pushing the lever ball 903 will move the insertion cylinder 901 through the insertion rod 902, thereby driving the sliding frame 8 to push the large blade 10 to perform cutting work along the preset trajectory.

[0035] Refer to the instruction manual appendix Figure 2 The outer shell 1 has a sliding groove 13 on its surface. The plug rod (902) extends out of one end of the plug tube 901 and passes through the sliding groove 13. The lever ball 903 is set on the outer surface of the outer shell 1.

[0036] It should be noted that the sliding groove 13 provides space for the movement of the insertion rod 902, and the lever ball 903 is located on the outside for easy pushing. At the same time, it matches the overall shape of the device, making it unique and aesthetically pleasing.

[0037] Refer to the instruction manual appendix Figure 2 and Figure 3 A fixing groove 14 communicating with the sliding groove 13 is provided on one side of the open end of the outer shell 1. A fixing plate 15 is fixedly connected to the large knife holder 3, and one end of the fixing plate 15 is engaged in the fixing groove 14.

[0038] It should be noted that by embedding the fixing plate 15 into the fixing groove 14, the large blade holder 3 can be installed inside the outer shell 1, and it can also be removed to facilitate the emptying and cleaning of the large amount of debris stored inside.

[0039] Refer to the instruction manual appendix Figure 6 and Figure 7 Two guide rails 16 are fixedly connected to the large knife holder 3. Slide bars 17 are slidably arranged inside the guide rails 16. The two slide bars 17 are fixedly connected to both sides of the sliding frame 8 respectively.

[0040] It should be noted that when the sliding frame 8 is pushed to move along the preset trajectory, the slide bar 17 slides within the guide rail 16, maintaining the stability of the movement of the sliding frame 8.

[0041] Refer to the instruction manual appendix Figure 8 and Figure 9 A blade pressure plate 18 is attached to the surface of the large blade 10, and a clamping head 19 is fixedly connected to the blade pressure plate 18. A slot 20 for the clamping head 19 to be inserted is provided on the sliding frame 8.

[0042] It should be noted that when installing the large blade 10, first insert the large blade 10 into the sliding frame 8, then embed the blade pressure plate 18 tightly against the surface of the large blade 10, and at the same time insert the clip 19 on the blade pressure plate 18 into the slot 20 to achieve a stable installation of the large blade 10 on the sliding frame 8.

[0043] Working principle: Component assembly and preparation During assembly, the large blade holder 3 is secured in the fixed groove 14 at the open end of the outer shell 1 by its fixing plate 15, achieving a stable installation; the large blade 10 is fixed in the slot 20 of the sliding frame 8 by the clamping head 19 of the blade pressure plate 18; the sliding strips 17 on both sides of the sliding frame 8 are embedded in the guide rail 16 of the large blade holder 3, ensuring smooth sliding along the preset trajectory; the insertion cylinder 901 of the pushing mechanism is fixed to the sliding frame 8; the insertion rod 902 passes through the sliding groove 13 of the outer shell 1, with one end inserted into the insertion cylinder 901 and the other end connected to the lever ball 903 and placed on the outside of the outer shell 1; the upper cover 2 is threadedly connected to the threaded groove 22 of the semi-circular spherical shell of the outer shell 1 by the internal threaded ring 21; the small blade holder 4 inside carries the small blade 12, completing the overall assembly and preparing for cutting.

[0044] Step 1: Cut the pen barrel to expose the lead. The user inserts the eyebrow pencil to be processed through the through hole 11 on the surface of the top cover 2 into the circular slot 7 of the knife holder 4, manually rotates the eyebrow pencil to make the pencil barrel contact the small blade 12, and removes the outer pencil barrel by the cutting of the small blade 12 until the inner pencil lead is exposed, and then pulls the eyebrow pencil out of the circular slot 7.

[0045] Step 2: Cut the pen lead to form three shapes Insert the eyebrow pencil with the exposed lead into the circular slot 5 of the blade holder 3 from the outer casing 1, so that the exposed part of the lead extends out of the cutting groove 6. By pushing the lever ball 903, the insertion rod 902 moves along the sliding groove 13, which in turn pushes the insertion cylinder 901 and the sliding frame 8, so that the large blade 10 cuts the lead outside the cutting groove 6. The specific operation to form three shapes is as follows: Semicircular: After the first push of the sliding frame 8 and the large blade 10 completes one cut, the eyebrow pencil is directly removed, and the pencil lead forms a semicircle; Triangular shape: After the first cut to form a semi-circle, take out the eyebrow pencil, rotate it 90 degrees, push the lever ball 903 to push the sliding frame 8 and the large blade 10 back to their original positions, insert the pencil lead again, and push the sliding frame 8 again to cut to form a triangular shape; Duckbill shape: After the first cut to form a semi-circle, take out the eyebrow pencil, push back the sliding bracket 8 and the large blade 10, rotate the pencil lead 180 degrees and reinsert it into the circular slot 5, and push the sliding bracket 8 to cut again to form a duckbill shape.

[0046] Subsequent debris cleaning If debris accumulates in the small knife holder 4 or the large knife holder 3, the top cover 2 can be unscrewed to clean the debris inside the small knife holder 4, disengage the fixing plate 15 from the fixing groove 14, remove the large knife holder 3, clean the internal debris, and then reassemble it for reuse.

[0047] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
