Description

Modular cosmetic brush

Technical Field

The invention relates to a modular cosmetic brush. More particularly, the present invention relates to a modular cosmetic brush in which brush heads of various specifications are received in a handle compartment, and bristles are automatically exposed to the outside of the compartment in cooperation with an opening operation of a cover by improving a structure so that anyone can easily exchange the bristles, and in particular, since the bristles are inserted and protected in a ferrule in a gathered state by a simple operation, a volume when not in use can be reduced to a half, and damage of the bristles can be prevented during a preservation process.

Background

In general, a cosmetic brush or art brush is used by carrying various cosmetic brushes in a set, so that bristles of each cosmetic brush are integrated with a body according to functions thereof. Since it is necessary to select the bristles corresponding to their purposes one by one when used, there is an inconvenience of carrying a variety of brushes.

For example, in the case of a cosmetic brush, it is composed of a cosmetic brush to which a cosmetic is applied, a cosmetic brush fixing collar to which the cosmetic brush is fixed, and a brush body which is extended to a suitable length to be held by hand and to which the cosmetic brush fixing collar is fixed at its end, and is formed in a rod or bar shape so as to be easily grasped. Since the brush is fixed to the brush holder ring, which is integrally fixed to the brush body, the brush holder ring is used in different ways according to different types of brushes, such as lipstick, powder eye shadow, liquid mascara, blush, etc., which results in the need to prepare a cosmetic brush in which a larger volume of brush holder ring and brush body are integrally formed. Therefore, not only the purchase cost is increased, but also the user has to carry various makeup brushes when traveling, particularly, when carrying the makeup brushes at a photographic scene, etc., which causes a problem of great inconvenience in carrying the makeup brushes due to their large size and weight.

Therefore, in the previously disclosed utility model registration No. 20-0404018, a technique has been registered in which a rotating plate member having a conversion brush body on both sides (front and rear) of a fixed brush body is provided. The rack of the rotating plate member is moved by the rotation of the pinion gear mounted on the brush rotating rod, and the rotating plate member is rotated in opposite directions around the spindle nut, thereby spreading the cosmetic brush of the transfer brush body to both sides of the cosmetic brush of the fixed brush body.

However, the above-mentioned prior art has disadvantages in that when a blush is applied to a face, it is necessary to apply the blush while spreading or collecting a cosmetic brush according to the order of makeup, but it is inconvenient to use because of a complicated structure and a heavy weight, and in particular, when various cosmetic brushes are carried, not only is the volume increased to deteriorate portability, but also the cosmetic brushes cannot be easily replaced.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The invention relates to a modularized cosmetic brush, which is characterized in that brush heads with various specifications contained in a handle compartment are automatically exposed out of the compartment in cooperation with the opening operation of a cover part through improving the structure, so that anyone can easily replace the modularized cosmetic brush; in particular, the main portion is configured to include the handle 10, the cover 20, the brush head 30, the hanging portion 40, and the elevating portion 50 in order to reduce the volume when not in use and prevent damage to the bristles during storage by inserting and protecting the bristles in a collapsed state in the ferrule with ease of operation.

The handle 10 according to the present invention has a compartment 12 formed therein, a fixed connector 14 provided at a distal end thereof, and a cover 20 provided to open and close the compartment 12 while moving linearly along a longitudinal direction of the handle 10.

Here, according to another embodiment, as shown in fig. 10 to 11, instead of the above-described lid section 20, it may be composed of a lid barrel 20a formed in such a manner as to wrap the handle 10, and it may also be combined with the handle 10 by being replaced with a C-shaped lid barrel 20b having a shape corresponding to the compartment 12. The cover cylinder 20a or the C-shaped cover cylinder 20b may be configured to slide or rotate along the length direction of the handle 10 to open and close the compartment 12.

Further, it may be configured such that the hooking part 40 is rotated by a worm gear when the compartment 12 is opened and closed by the cover cylinder 20a or the C-shaped cover cylinder 20 b.

Also, as shown in fig. 1 to 2, a plurality of brush heads 30 may be accommodated in the compartment 12, and a multi-directional coupling member 32 is provided at the brush heads 30 so that any one of the brush heads 30 is selectively drawn out and coupled to the fixed coupling member 14 of the handle 10. Various embodiments of brush head 30 will be described in detail with reference to figures 3-19, which are described below.

In one aspect, although the fixed connector 14 and the multidirectional connector 32 are preferably provided to be attracted by a magnet, the present invention is not limited thereto, and a structure may be adopted in which the user directly attaches and fixes the fixed connector 14 and the multidirectional connector 32 by forming the attachment groove and the attachment hole, respectively.

The hanging part 40 according to the present invention is provided at a plurality of positions in the compartment 12, and is provided with a hanging projection 44 which rotates around the rotation shaft 42 or the rotation projection 42a and is connected to the multidirectional connector 32 of the brush head 30. That is, the multi-directional coupler 32 of the brush head 30 is housed in the compartment 12 in a state of being fitted to the hanging projection 44 of the hanging part 40, and one end of the brush head 30 is exposed to the outside of the compartment 12 by the rotational movement of the hanging part 40, thereby being easily taken out. At this time, the rotation of the hook 40 is automatically performed by the lifter 50 described later.

At this time, the elevating portion 50 is configured to expose the brush head 30 to the outside of the compartment 12 by rotating the hanging portion 40 along an inclined angle in accordance with the opening operation of the lid portion 20.

In fig. 3, the elevating part 50 is composed of a pinion gear 45 provided on a concentric circle of the rotation shaft 42 of the hanging part 40 or the rotation protrusion 42a in fig. 3(d), and a rack gear 25 provided on the lid part 20 in such a manner as to be coupled with the pinion gear 45, and the rack gear 25 is provided at the tip end of the lid part 20.

Therefore, when the above-mentioned lid section 20 is opened, it is configured that, if the tip end of the lid section 20 is moved to be adjacent to the hook section 40, the pinion 45 is coupled with the rack 25 and performs a rotational motion, and the brush head 30 is rotated along the inclination angle by the rotational motion of the hook section 40 to be exposed to the outside of the compartment 12. The pinion gear 45 and the hanging portion 40 may be formed as one piece or may be formed of two pieces.

According to another embodiment of the present invention, in fig. 4, instead of the rack 25, a saw tooth 25a may be integrally formed at an end portion of the cover 20.
