Abstract
Description
Technical Field
[0001] The utility model relates to a makeup brush, in particular to a makeup flat brush. Background Art
[0002] The traditional flat brush structure is to glue a bunch of round brushes into an aluminum tube and tighten them with the aluminum tube. After drying, use a tool to flatten the end of the aluminum tube close to the brush to form a flat brush shape. Finally, the aluminum tube combined with the brush is glued to a plastic rod.
[0003] However, conventional brushes are fixed with glue, which is not environmentally friendly. Glue is compatible with some chemical agents (cosmetic liquids), and there is a risk that the brush is easily separated from the aluminum tube or the aluminum tube is easily separated from the plastic rod. In addition, since most plastic rods are cylindrical, the brush and the plastic rod must be connected through an aluminum tube of a corresponding shape, and then the aluminum tube is clamped and flattened at one end close to the brush using a tool to complete the production of the flat brush. The flat brush cannot be directly fixed in the cylindrical plastic rod. Therefore, in addition to increasing the cost of the aluminum tube, the production process of the conventional brush is also more complicated.
[0004] In view of this, the creator, based on his many years of experience in manufacturing, developing and designing related products, has designed and carefully evaluated the above-mentioned goals and finally obtained a practical utility model. Utility Model Content
[0005] The utility model aims to provide a flat brush for makeup, which has a simple structure, is easy to operate, can save costs, simplifies the manufacturing process, is more environmentally friendly, is more firmly fixed, has strong applicability, and is more practical.
[0006] To achieve the above object, the utility model discloses a cosmetic flat brush, which is characterized by comprising:
[0007] A rod body, one end of which extends a connecting portion, the connecting portion is in a conical shape, the outer diameters of the upper and lower sides of the connecting portion gradually decrease toward the free end surface thereof, a positioning hole is arranged in the connecting portion along the long axis direction thereof, and the outer surface of the rod body is provided with a through hole on the left and right sides of the positioning hole respectively, the through holes are arranged opposite to each other, and each through hole is connected to the positioning hole respectively;
[0008] A flat brush is arranged in the positioning hole of the rod body. The flat brush has a smearing section and a melting section. The smearing section is exposed at the joint part. The melting section is flat and accommodated at the bottom of the positioning hole. The positions of the perforations are arranged corresponding to the melting section.
[0009] The shape of the positioning hole corresponds to the flat shape of the molten section of the flat brush.
[0010] Wherein, the other end of the rod body is connected to a gripping portion.
[0011] Wherein, the rod body is made of plastic.
[0012] Due to the above structure, the rod body and the flat brush of the utility model do not need to be connected through an aluminum tube, thereby saving costs and simplifying the manufacturing process. There is no need to use glue for fixing. In addition to being environmentally friendly, it can also prevent the glue from being compatible with chemical agents and causing the flat brush to fall off. Furthermore, the positioning hole is arranged in a flat rectangular shape, so that the flat brush can be implanted in a corresponding shape, and the flat brush can meet the user's various makeup needs.

[0017] See also Figures 1 to 4 As shown, it discloses a cosmetic flat brush, which includes:
[0018] A rod body 10 is made of plastic. A connecting portion 11 is extended from one end of the rod body 10. The connecting portion 11 is slightly conical. The outer diameters of the upper side 11a and the lower side 11b of the connecting portion 11 gradually decrease toward the free end surface. A positioning hole 111 is arranged in the connecting portion 11 along its long axis direction. A through hole 112 is respectively arranged on the left and right sides corresponding to the positioning hole 111 on the outer surface of the rod body 10. The through holes 112 are arranged opposite to each other. Each of the through holes 112 is respectively connected to the positioning hole 111. The other end of the rod body 10 is connected to a gripping portion 12 for the user to hold when applying makeup.
[0019] A flat brush 20 is disposed in the positioning hole 111 of the rod body 10. The flat brush 20 has a smearing section 21 and a melting section 22. The smearing section 21 is exposed at the joint 11. The melting section 22 is flat and is accommodated at the bottom of the positioning hole 111. The positions of the through holes 112 are arranged corresponding to the melting section 22.
[0020] The shape of the positioning hole 111 corresponds to the shape of the flat brush 20, so that the molten section 22 of the flat brush 20 can be conveniently inserted into the corresponding position, and the perforations 112 can be set after the insertion, so that the aperture of the positioning hole 111 corresponding to the position of the perforations 112 can be reduced, thereby tightening the molten section 22 of the flat brush 20 to prevent the flat brush 20 from falling off. Figure 4 shown.
[0021] See also Figure 3 and Figure 4 As shown, before assembly, the utility model first trims the messy part of the smear section 21 of the flat brush 20, and then implants the flat brush 20 into the positioning hole 111 of the rod body 10, so that the fused section 22 is accommodated at the bottom of the positioning hole 111, and the smear section 21 is exposed at the joint 11, and finally a punch is used to drill the through holes 112 on the outer surface of the rod body 10 at the left and right sides corresponding to the positioning hole 111 and at the positions corresponding to the fused section 22, so that the aperture of the positioning hole 111 at the positions corresponding to the through holes 112 can be reduced, thereby tightening the fused section 22, and preventing the flat brush 20 from falling off. Preferably, the shape of the positioning hole corresponds to the flat shape of the fused section of the flat brush.
[0022] Thus, through the above structure, the rod body 10 and the flat brush 20 of the utility model do not need to be connected through an aluminum tube, so that costs can be saved, and the manufacturing process is simplified. There is no need to use glue to fix them. In addition to being environmentally friendly, it can also prevent the glue from being compatible with chemical agents and causing the flat brush 20 to fall off. Furthermore, the positioning hole 111 is set in a flat rectangular shape, so that the flat brush 20 can be implanted in a corresponding shape, and the flat brush 20 can meet the various makeup needs of the user. For example, the wider part A of the application section 21 of the flat brush 20 can be applied to a large area horizontally, which is suitable for applying liquid lipstick to lips or rough eyebrows, such as Figure 1 As shown, the narrower portion B of the smearing section 21 of the flat brush 20 can be used for smearing on a small area according to more subtle needs, such as lip lines, eye grooves or eyebrow ends, etc. Figure 2 As shown, in addition, the front edge of the smearing section 21 is designed to be pointed, which is suitable for spot brushing.
