[0029] See Figures 1 to 4This utility model discloses a conveniently assembled makeup brush, comprising: a bristle assembly 100 and a long strip-shaped first half-shell 200 and a second half-shell 300. The first half-shell 200 and the second half-shell 300 are joined together to form a brush handle. The upper part of the first half-shell 200 is provided with a first mounting groove 210 with a side opening, and the upper part of the second half-shell 300 is provided with a second mounting groove 310 with a side opening opposite to the first mounting groove 210. The lower part of the bristle assembly 100 is provided with a skirt 110. The second mounting groove 310 and the first mounting groove 210 are joined together to form a mounting cavity for clamping and fixing the skirt 110. The upper end of the first half-shell 200 is provided with a vertically upward first semi-opening 220, and the upper end of the second half-shell 300 is provided with a vertically upward second semi-opening 320 opposite to the first semi-opening 220. The second semi-opening 320 and the first semi-opening 220 together define a defined channel for the bristles of the bristle assembly 100 to extend.
[0030] The brush handle of the above-described makeup brush is composed of a first half-shell 200 and a second half-shell 300. The bristle assembly 100 has a skirt 110. During assembly, a portion of the skirt 110 is embedded in the first mounting groove 210. When the first half-shell 200 and the second half-shell 300 are assembled, the other portion of the skirt 110 is embedded in the second mounting groove 310, so that the skirt 110 is clamped in the mounting cavity. The bristles of the bristle assembly 100 extend upward from the defined channel. No glue is needed to fix the bristle assembly 100, which is very environmentally friendly. Moreover, the manufacturing difficulty and cost of the makeup brush are relatively low, which is also conducive to the consistency of product quality.
[0031] In this embodiment, the limiting channel is cylindrical, and the hairs extending from the limiting channel are divergent. The limiting channel has a limiting effect on the divergent state of the hairs. For example, the diameter of the limiting channel can be reduced to increase the degree of hair convergence, or the shape of the limiting channel can be modified to a frustum shape with a smaller bottom and a larger top to enhance the degree of hair divergence.
[0032] See Figure 2 and Figure 3 In some embodiments of this utility model, the upper end of the first half-shell 200 is recessed downward to form a first recessed groove 230, and the inner peripheral wall of the first recessed groove 230 is recessed inward to form a semi-circular first mounting groove 210. The skirt 110 is annular. The upper end of the second half-shell 300 is recessed downward to form a second recessed groove 330, and the inner peripheral wall of the second recessed groove 330 is recessed inward to form a semi-circular second mounting groove 310. After the first recessed groove 230 and the second recessed groove 330 are assembled, they automatically form a mounting cavity and a defined channel. Both the mounting cavity and the skirt 110 are annular to facilitate manufacturing.
[0033] See 2 to Figure 4In some embodiments of this utility model, the bottom surface of the first recess 230 is provided with a first semi-annular protrusion 240, and the bottom surface of the second recess 330 is provided with a second semi-annular protrusion 340. The first semi-annular protrusion 240 and the second semi-annular protrusion 340 are spliced together to form an annular protrusion that drives the skirt 110 to press upward against the mounting cavity. It can be understood that when the skirt 110 of the bristle assembly 100 is clamped and fixed by the second mounting groove 310 and the first mounting groove 210, it is subjected to a radial clamping force. In the height direction of the mounting cavity, the constraint force on the skirt 110 is insufficient, which can easily cause the bristle assembly 100 to move up and down. The annular protrusion can improve this problem.
[0034] In some embodiments of this utility model, the height dimension of the mounting cavity is A, and the height dimension of the annular protrusion is B, satisfying: 1mm≤A≤1.5mm, 0.1A≤B≤0.3A. It is understood that if the height dimension of the annular protrusion is too large, it will be difficult for the skirt 110 to be inserted into the second mounting groove 310 and the first mounting groove 210, affecting the assembly effect. If the height dimension of the annular protrusion is too small, it will be difficult to effectively push the skirt 110 upwards and tightly against the mounting cavity. Through testing, it has been found that when the above conditions are met, the makeup brush can achieve a good assembly effect.
[0035] In some embodiments of this utility model, the lower ends of the bristles of the bristle assembly 100 are fused together to form a flat plate, and the portion of the flat plate protruding from the outer periphery of the bristle assembly 100 constitutes the skirt 110. It is understood that when the lower ends of the bristles of the bristle assembly 100 are placed on a high-temperature heating plate, the lower ends of the bristles of the bristles of the bristle assembly 100 will be fused together, and the molten fluid portion of the bristles will overflow to the outer periphery to form the skirt 110. No additional components are needed, and this effectively prevents the bristles from easily falling off.
[0036] In some embodiments of this utility model, the bristle assembly 100 includes a plastic pad and bristles. The lower end of the bristles is fused to the plastic pad, and the portion of the plastic pad protruding from the outer periphery of the bristles constitutes the skirt 110. It is understood that during production, the lower end of the bristles can be melted and pressed against the plastic pad. The fusion effect between the plastic pad and the bristles is good, and it is not easy for them to fall off. Moreover, the portion of the plastic pad serving as the skirt 110 has high mechanical strength, which is beneficial for stably clamping and fixing the bristle assembly 100.
[0037] See 2 and Figure 3In some embodiments of this utility model, to facilitate the assembly of the first half-shell 200 and the second half-shell 300 into a brush rod, the first half-shell 200 and the second half-shell 300 are joined together by a plug-in structure. Of course, in other embodiments, the first half-shell 200 and the second half-shell 300 can also be connected by adhesive, magnetic attraction, threaded connection, or other methods.
[0038] See 2 and Figure 3 In some embodiments of this utility model, the first half-shell 200 is provided with a first slot 250 and a first protrusion 260 on its two sides along its length direction, and the second half-shell 300 is provided with a first insert 350 that mates with the first slot 250 and a first groove 360 that mates with the first protrusion 260 on its two sides along its length direction. Specifically, the first slot 250 is located on the left side of the first half-shell 200, the first protrusion 260 is located on the right side of the first half-shell 200, the first insert 350 is located on the right side of the second half-shell 300, and the first groove 360 is located on the left side of the second half-shell 300. When the first insert 350 is aligned with the first slot 250 and inserted, and the first protrusion 260 is aligned with the first groove 360 and inserted, the first half-shell 200 and the second half-shell 300 can be assembled to form a brush rod.
[0039] See 2 and Figure 3 In some embodiments of this utility model, the first slot 250 and the first protrusion 260 both extend along the length direction of the first half-shell 200. The first slot 250 has the same structure as the first groove 360, and the first protrusion 260 has the same structure as the first insert 350. It can be understood that when the structures of the first half-shell 200 and the second half-shell 300 are completely identical, that is, when the requirements of the first slot 250 and the first groove 360 having the same structure, and the first protrusion 260 and the first insert 350 having the same structure are met, the first half-shell 200 and the second half-shell 300 can be formed using only one mold cavity, greatly reducing equipment costs and processing costs, and improving production efficiency. At this time, the structures of the first mounting groove 210 and the second mounting groove 310 are also completely identical.
[0040] See 2 and Figure 3In some embodiments of this utility model, both the first half-shell 200 and the second half-shell 300 are provided with vertical stiffeners 400 extending along their length direction and multiple horizontal stiffeners 500 extending along their width direction. The multiple horizontal stiffeners 500 are arranged at intervals along the length direction of the first half-shell 200 or the second half-shell 300 to form multiple material-saving grooves 600. It should be noted that when the first half-shell 200 and the second half-shell 300 are produced by injection molding, injection shrinkage is likely to occur. Providing multiple material-saving grooves 600 can not only save raw materials but also improve the injection shrinkage phenomenon. Specifically, the wall thickness of the first half-shell 200 and the second half-shell 300 is approximately equal to the thickness of the vertical stiffeners 400 and the horizontal stiffeners 500.
[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
