Brush with groove in makeup brush factory and makeup device including the brush

Today, our makeup brush factory will introduce you a brush with grooves. The surface 106.2 is convex, and all the surfaces of the brush (the tapered surface 101 notch front 106 and the notch back 106.2) are composed of bus bars, which converge at a fixed point P located on the central axis 1 of the brush. The intersection of the two faces 106 and 106 defines a straight groove line 107, which also converges at P. The intersection of the front surface 106.1 of the notch and the surface of the envelope of the brush 101 defines a straight peak ridge 108.1 converging on P. As shown in Figures 1A and 1B, the back 106 of the notch of the brush 101 is circular, and its radius is adjustable so that the back 106 of the notch is tangent to the surface 101 of the brush envelope, but according to a variant, 106 and 101 can be selected as Intersect to determine the second peak ridge. The front surface of the notch 106 has a height, and the back of the notch has a height H, and the height varies along the core member. The relationship of h<1/2H is satisfied in each plane segment of the brush. The groove 106 is obtained by the trimming brush 101, that is, the bristles 104 of the brush are trimmed with a trimming tool. The groove 106 is located on one side of the brush, so it does not cross the core 102. The brush shown in Fig. 10 differs from that shown in Fig. 1 in that it includes two separate curved sections, S with a cylindrical sealing envelope surface 111.11, and a conical brush with the brush shown in Fig. 1 The other two sections of the envelope surface 111.2 are assembled by their bases of the same diameter. The notch front 116 and the notch back 116.2 extend through these two sections. Their respective heights h and H remain unchanged throughout the cylindrical section S1, and then decrease along the conical section S2. The B angle between the front side 116 of the notch and the back side 116.2 of the notch is constant over the entire axial length of the brush. The slot line consists of two line segments; line segment 117, in the cylindrical section, parallel to the axis of the core member, line segment 117, in the conical section, converging at a point on the axis of the core member, this type of brush can obtain advantageous makeup Variety. The brush 20 shown in FIG. 2 is different from those shown in FIGS. 1A and 1B in that it has four identical grooves. Each groove occupies a 90-degree area of u200bu200bthe brush surface. The peaks and ridges of two consecutive grooves coincide. The straight notch front 206 of a groove and the circular notch back 206 of the front groove together define a notch 210 and a peak line 208. The surface of the brush 201 has four protruding notches separated by four groove lines 206, and these notches come from a 90-degree rotation around the central axis II-II of the brush. An observer at the side end of the brush rod can see a series of right-facing notches in the given notch 210, and the straight front side 206 of the notch is located on the right side of the back side 206.2 of the circular notch. The pitch circle of the brush is thus right-handed. According to a variant of the present invention, the pitch circle can also be predetermined to be left-handed. It is also possible to pre-determine the brush with two consecutive sections, one with a left-handed pitch circle and the other with a right-handed pitch circle. The pitch circle is preferably aligned over the entire length of the brush. The difference between the brush 301 shown in FIG. 3 and the brush in FIG. 2 is that it includes three notches 310, each occupying an area with an angle of 120 degrees.
