Description

Technical Field

[0001] This utility model relates to the field of cosmetics, specifically to a fine-bristle brush tip assembly. Background Technology

[0002] Eyebrow pencils are used to enhance and accentuate the eye makeup, making the eyes appear larger and more expressive. As a makeup product, eyebrow pencils are widely used, with liquid eyebrow pencils being particularly popular due to their ease of use and other advantages.

[0003] The liquid eyebrow pencil has an internal water-retaining core, one end of which connects to the liquid reservoir and the other end extends to the base of the brush, continuously supplying the brush with makeup liquid. The brush is installed inside the tip, with its tip extending from the brush outlet at the top of the tip. When the brush outlet diameter is 1.7mm, the bristles inside the tip are coarse; when the diameter decreases to 1.0-1.1mm, the bristles are fine. Compared to coarse brushes, fine brushes can produce a more refined effect. However, in practical use, the fewer bristles on fine brushes result in insufficient water retention, causing the makeup liquid on the brush to evaporate easily, leading to the brush drying out and affecting its usability. Utility Model Content

[0004] Based on this, and in response to the above problems, this utility model provides a pen tip assembly.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A fine brush tip assembly includes a brush tip, a brush, and a water-guiding core. The rear end of the brush is fixed inside the brush tip, and the tip of the brush extends out of the brush tip. The front end of the water-guiding core is connected to the brush. A water-retaining sleeve is also provided between the brush and the brush tip.

[0007] By adopting the above structure and setting a water-retaining sleeve between the brush tip and the brush, the water retention capacity of the brush is improved, allowing the brush to remain moist for a long time.

[0008] In a specific embodiment of this utility model: the upper end of the water-retaining sleeve extends upward to form the brush tip. This structure allows the cosmetic liquid to converge towards the brush tip as much as possible, further enhancing the brush's moisturizing effect and enabling it to remain soft and less prone to drying out for a longer period.

[0009] In a specific embodiment of this utility model: the distance from the tip of the brush to the upper edge of the water storage sleeve is 2.5mm-3.5mm.

[0010] In a specific embodiment of this utility model: the water storage jacket is made of polyester fiber.

[0011] In a specific embodiment of this utility model: it also includes a middle section sleeve, the pen tip is connected to the front section of the middle section sleeve, and the water guide core is disposed inside the middle section sleeve.

[0012] In summary, this invention improves the water retention capacity of the brush by incorporating a water-retaining sleeve between the brush tip and the bristles, allowing the fine bristles to remain moist for an extended period. Furthermore, the upper end of the water-retaining sleeve extends upwards towards the brush tip, causing the cosmetic liquid to converge at the tip of the brush, further enhancing the moisturizing effect of the fine bristles and enabling them to remain soft and resistant to drying out for a longer time.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1As shown, this embodiment provides a fine-bristle eyebrow pencil, including a pen holder 100, a pen tip 200, a water inlet core 400, an adjuster 500, a middle section sleeve 600, a brush 700, a pen cap 800, and a water reservoir sleeve 900. The pen tip 200, brush 700, water inlet core 400, middle section sleeve 600, and water reservoir sleeve 900 constitute the fine-bristle pen tip assembly.

[0024] like Figure 1 , Figure 2 and Figure 8 As shown, the pen barrel 100 has a reservoir 300 for storing cosmetic liquid. A raised ring 610 on the outer circumference of the middle section 600 divides it into a rear section 620 and a front section 630. The rear section 620 is tightly fitted into the inner cavity of the pen barrel 100 along the front end. Annular protrusions 640 are provided on the outer circumference of the rear section 620, and annular recesses 110 on the inner wall of the pen barrel 100 mate with these protrusions 640. The annular protrusions 640 on the rear section 620 engage with the annular recesses 110 on the inner wall of the pen barrel 100, thus sealing and fixing the pen barrel 100 to the middle section 600.

[0025] Please see Figure 1 , Figure 3 and Figure 4 As shown, the middle sleeve 600 has an internal regulator mounting cavity 230 that extends through its front and rear ends. The regulator 500 is inserted into the regulator mounting cavity 230. The regulator 500 has a through-hole 400 for water inlet. The water inlet 400 is made of fiber material and is inserted into the water inlet hole 510. The rear end of the water inlet 400 is located in the liquid storage cavity 300, and the front end extends out of the water inlet hole 510 to connect with the tail end of the brush 700. This regulator 500 is prior art and will not be described in detail here.

[0026] like Figure 6 and Figure 7 As shown, the pen tip 200 includes a pen tip mounting portion 210 inserted into the middle section sleeve and a tapered end 220 located in front of the pen tip mounting portion 210. A locking block 211 is provided on the outer circumferential surface of the pen tip mounting portion 210, and a locking groove 670 that mates with the locking block 211 is provided on the inner wall of the middle section sleeve 600. By locking the locking block 211 of the pen tip mounting portion 210 into the locking groove 670 of the middle section sleeve 600, the pen tip 200 is fixedly connected to the middle section sleeve 600, and thus the pen tip 200 is fixedly connected to the pen barrel 100.

[0027] The pen tip 200 is provided with a venting groove 212. In this embodiment, two venting grooves 212 are provided, and the two venting grooves 212 are symmetrically arranged along the central axis of the pen tip. The venting grooves 212 extend upward from the lower edge of the pen tip mounting part 210 to the rear end face of the tapered end 220. With this structure, the airflow inside the pen barrel 100 is exchanged with the outside through the venting grooves 212, so as to balance the air pressure inside and outside the pen barrel and avoid the ink flow blockage of the water-based pen.

[0028] like Figure 7 As shown, the interior of the pen tip 200 is divided into an adjuster insertion hole 230 and a brush mounting hole 240. The adjuster insertion hole 230 extends from the rear end face of the pen tip 200 to the interior of the tapered end 220. The brush mounting hole 240 extends from the adjuster insertion hole 230 to the front end face of the pen tip 200. The diameter of the adjuster insertion hole 230 is larger than the diameter of the brush mounting hole 240, forming a stop positioning step 250 between the adjuster insertion hole 230 and the brush mounting hole.

[0029] like Figure 5 and Figure 7 As shown, the brush 700 includes a main conical head 710 and a positioning plate 720 connected to the rear end of the main conical head 710 and protruding from its outer peripheral surface. The main conical head 710 is made of PBT material, and the positioning plate 720 is made of plastic material. The brush is installed in the brush mounting hole 240, with the tip of the main conical head 710 extending out of the brush mounting hole 240. The front end face of the adjuster 500 abuts against the rear end face of the positioning plate 720, causing the front end face of the positioning plate 720 to abut against the stop positioning step 250. This achieves isolation between the adjuster insertion hole 230 and the brush mounting hole 240, preventing cosmetic liquid from leaking directly from the adjuster insertion hole 230 along the brush mounting hole. At the same time, by abutting the positioning plate 720 against the stop positioning step 250, the brush head 700 is fixed, and the main conical head 710 is fixed in the brush mounting hole.

[0030] The brush 700 has a water-guiding core mounting hole 730 extending axially into the brush 700. The front end of the water-guiding core 400 is interference-fitted into the water-guiding core mounting hole 730, thus fixing the brush 700 to the water-guiding core 400.

[0031] A water reservoir 900 is positioned between the brush tip 200 and the brush 700. The water reservoir 900 can be made of polyester fiber. The water reservoir 900 has a conical structure. The water reservoir improves the water retention of the brush, allowing it to remain moist for extended periods under both normal and high-temperature conditions.

[0032] In this embodiment, the upper end of the water-retaining sleeve 900 extends upward to form the brush tip 200. This structure allows the cosmetic liquid to converge towards the tip of the brush, further enhancing the moisturizing effect of the brush and enabling it to remain soft and less prone to drying out for a longer period of time. The distance from the tip of the brush 700 to the upper edge of the water-retaining sleeve is 2.5mm-3.5mm.

[0033] Please see Figure 1 As shown, the pen cap 800 is closed at one end and open at the other, with an internal cavity. An inner cover 810 is provided inside the pen cap 800, which divides the internal cavity into a separate storage cavity 820 and a storage cavity 830. The pen cap 800 is fastened onto the middle section sleeve 600, with the open end of the pen cap 800 abutting against the convex ring 610 and stopped by it. The brush 700 is located within the storage cavity 820. Using the inner cover 810 reduces the space within the pen cap 800 used to store the brush 700, thereby reducing the amount of air remaining inside the pen cap 800 after it is fastened to the middle section sleeve, extending the time required for the cosmetic liquid on the brush 700 to dry after sealing, and increasing the duration of moisture on the brush 700.

[0034] In this embodiment, the pen barrel 100, pen tip 200, adjuster 500, middle section sleeve 600, and pen cap 800 are all plastic parts.

[0035] During assembly, first assemble the regulator 500, water inlet core 400, and brush 700 into the middle section sleeve 600, then install the middle section sleeve 600 into the pen barrel 100, put the water storage sleeve 900 onto the brush 700, and install the pen tip 200. Finally, snap the pen cap 800 onto the middle section sleeve 600.

[0036] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
