Description

Technical Field

[0001] The utility model relates to the technical field of cosmetics, in particular to a cosmetic brush. Background Art

[0002] A makeup brush is a tool used to apply makeup. Different brushes differ depending on the area they're applied to. For example, if applied to eyelashes, they're called eyelash brushes. Currently, most eyelash brushes on the market use plastic or steel wire bristles, but these materials have some significant drawbacks. For example, plastic bristles aren't dense enough and don't pick up much makeup, so multiple passes are required to achieve a fuller look. This involves repeatedly pumping the brush head in and out of the mascara tube to apply the makeup. However, this allows more air to enter the mascara, causing it to dry out more easily, leading to a greater chance of clumping on the eyelashes and bacterial growth. Furthermore, steel wire bristles, due to their inherent material, don't disperse the mascara well when applied, causing it to accumulate and form clumps on the bristles. Summary of the Invention

[0003] The purpose of the utility model is to provide a makeup brush, which can store cream in the spiral groove by setting the spiral groove, so that there is no need to frequently insert the mascara to dip the cream, and the spiral groove can divide the eyelashes into bunches, and each bunch of eyelashes has an oblique groove, so that the cream can be applied more evenly, thereby solving the problem that the existing cream is easy to clump and is unevenly applied.

[0004] The purpose of this utility model is achieved in this way:

[0005] A cosmetic brush comprises a brush rod, and a brush head made of metal is provided at one end of the brush rod, and a spiral groove is provided on the outside of the brush head, and the cross-section of the spiral groove is an isosceles trapezoid. The spiral groove is divided into multiple oblique grooves, and a protrusion is provided between two adjacent oblique grooves on the same side, and the cross-section of the protrusion is an isosceles trapezoid.

[0006] Preferably, a hemisphere is provided at one end of the brush head away from the brush rod, and a slope 1 is provided on the side of the hemisphere close to the spiral groove.

[0007] Preferably, the brush rod is provided with a second inclined surface on a side close to the spiral groove.

[0008] Preferably, the distance between two adjacent protrusions is the same, and the upper and lower widths and heights of each protrusion are the same.

[0009] Preferably, the upper width of each protrusion is 0.10 mm to 0.12 mm, the upper width of the spiral groove is 0.3 mm to 0.5 mm, and the lower width of the spiral groove is 0.6 mm to 1 mm.

[0010] Preferably, the angle between the two side surfaces of each protrusion is 39 degrees to 41 degrees.

[0011] Preferably, the number of turns of the spiral groove is 25-27 turns.

[0012] Preferably, the end of the brush rod away from the brush head is a mounting portion, and a limit block is provided on the mounting portion at the end away from the brush head, and a flat surface is formed on one side of the limit block so that it can be adapted to the brush rod seat and thus limit the rotation of the brush rod, and a mounting groove adapted to the brush rod seat is provided on the outside of the mounting portion.

[0013] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0014] The utility model is provided with a spiral groove so that the cream can be stored in the spiral groove, so there is no need to frequently insert the mascara to dip the cream, and the spiral groove can divide the eyelashes into bunches, and each bunch of eyelashes has an oblique groove, so that the cream can be applied more evenly.

[0015] At the same time, the metal material is easier to clean, and the raised cross-section is an isosceles trapezoid, not a triangle, which reduces sharpness and improves comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-Figure 5As shown, a cosmetic brush includes a brush rod 1, and a brush head 2 made of metal is provided at one end of the brush rod 1, and a spiral groove 21 is opened on the outside of the brush head 2, and the cross section of the spiral groove 21 is an isosceles trapezoid. At the same time, the spiral groove 21 is divided into multiple oblique grooves 211, and a protrusion 22 is provided between two adjacent oblique grooves 211 on the same side, and the cross section of the protrusion 22 is an isosceles trapezoid.

[0025] Therefore, in actual use, the spiral groove 21 is provided so that the cream can be stored in the spiral groove 21, so there is no need to frequently insert the mascara to dip the cream. Moreover, the spiral groove 21 can divide the eyelashes into bunches, and each bunch of eyelashes has an oblique groove 211, so that the cream can be applied more evenly.

[0026] At the same time, metal materials are easier to clean, and stainless steel can be selected. Moreover, the cross section of the protrusion 22 is an isosceles trapezoid, not a triangle, thereby reducing sharpness and improving comfort.

[0027] Furthermore, a hemispherical body 23 is provided at one end of the brush head 2 away from the brush rod 1 , and an inclined surface 1 is provided on one side of the hemispherical body 23 close to the spiral groove 21 .

[0028] Therefore, in actual use, the hemispherical body 23 is provided to reduce sharpness and improve comfort. In addition, the provision of the first bevel makes the cross section of the spiral groove 21 near the hemispherical body 23 also trapezoidal, which helps to better comb and shape the eyelashes.

[0029] At the same time, the brush rod 1 is provided with a second inclined surface on a side close to the spiral groove 21 .

[0030] Therefore, in actual use, the cross section of the spiral groove 21 close to the brush rod 1 is also trapezoidal due to the provision of the second inclined surface, which helps to better comb and shape the eyelashes.

[0031] like Figure 2 and Figure 4 As shown, the distance between two adjacent protrusions 22 is the same, and the upper and lower widths and heights of each protrusion 22 are the same.

[0032] The specific data are as follows: first, the upper width of each protrusion 22 is 0.10mm-0.12mm, the upper width of the spiral groove 21 is 0.3mm-0.5mm, and the lower width of the spiral groove 21 is 0.6mm-1mm. Moreover, the angle between the two sides of each protrusion 22 is 39 degrees to 41 degrees.

[0033] Therefore, in actual use, by setting the spacing, upper and lower widths and height to be the same, the paste can be applied more evenly.

[0034] like Figure 2 and Figure 4 As shown, the number of turns of the spiral groove 21 is 25-27, so that the paste can be applied more evenly.

[0035] like Figure 1-Figure 5 As shown, the end of the brush rod 1 away from the brush head 2 is a mounting portion, and a limit block 11 is provided on the mounting portion at the end away from the brush head 2, and a flat surface is formed on one side of the limit block 11 so that it can be adapted to the brush rod seat and thus limit the rotation of the brush rod 1, and a mounting groove 12 adapted to the brush rod seat is provided on the outside of the mounting portion.

[0036] Therefore, in actual use, the rotation of the brush rod 1 can be restricted by the arrangement of the plane, and the arrangement of the mounting groove 12 can also prevent the brush rod 1 from being separated from the brush rod seat during installation.

[0037] The above shows and describes the basic principles and main features of the present invention as well as the advantages of the present invention. At the same time, the present invention is not limited to the above embodiments. Therefore, various changes and improvements are possible without departing from the principles and scope of the present invention. Such changes and improvements fall within the scope of the present invention.
