The cover 90 is coupled to the outer bristles 60 to avoid the outer bristles 60 and the The inner bristles 80 are contaminated by external foreign matter.

An assembly method and a state of use of a face cleaning device having a bristle structure in which the inner bristles are located on the outer bristles according to an embodiment of the present invention will be described in detail.

In order to assemble a face cleaning device according to the present invention having a bristle structure with an inner bristles on the outer bristles, the drive motor 20 is mounted (which rotates clockwise or counterclockwise) to the body 10 (which includes the installation space) After the front body 11 and the rear body 15), the operation control unit 30 is mounted to control the operation of the drive motor 20. Then, after the power supply to the power supply unit 40 of the operation control unit 30 is installed, the front body 11 is coupled with the rear body 15.

The power transmission component 50 is coupled to the motor shaft 21 of the drive motor 20, and the motor shaft 21 protrudes from the front body 11 of the body 10; or after the motor shaft seal 22 has been coupled to the motor shaft 21, Power transmission element 50 is coupled to one of the motor shaft 21 fittings and the motor shaft seal bore 22.

Thereafter, as shown in FIG. 5, the inner bristles 80 are inserted into the bristles 60 having the outer side of the first hollow portion 61.

In this example, the annular boundary protrusion 81 formed on the outer peripheral surface of the inner bristles 80 is in contact with the locking step 62 formed inside the first hollow portion 61 of the outer bristles 60 to avoid the inner bristles 80. The outer bristles 60 are separated by the first hollow portion 61 of the outer bristles 60.

When the insertion of the inner bristles 80 is completed, the bristle holder 70 is fitted to an inner peripheral surface of the lower end of one of the outer bristles 60.

The bristle holder 70 is mated with the inner bristles 80 such that the bristle holder 70 does not separate from the inner bristles 80, thereby avoiding separation of the inner bristles 80.

The coupling ribs 82 of the inner bristles 80 are located in the second hollow portion 72 formed in the bristle holder 70.

When the inner bristles 80 are interposed between the outer bristles 60 and the bristle holder 70, the assembly work has been completed as described above, when the coupling grooves 64 of the outer bristles 60 are as shown in FIG. When coupled with the coupling protrusion 13 of the body 10, the coupling rib 82 of the inner bristles 80 is coupled to the power transmission element 50 of the body 10 such that the outer bristles 60 are coupled to the body 10 as shown in FIG. .

Thereafter, the assembly operation of the face cleaning device having the bristle structure of the inner bristles on the outer bristles according to the present invention is accomplished by coupling the cover 90 and the outer bristles 60.

When the outer bristles 60 and the inner bristles 80 coupled to the body 10 are decoupled from the body 10, the outer bristles and the inner bristles must be coupled to the body 10 and decoupled from the body 10, respectively, thereby causing inconvenience .

According to the present invention, since the inner bristles 80 are interposed between the outer bristles 60 and the bristle holders 70 and coupled with the body 10, the outer bristles 60 and the inner bristles 80 can be coupled to the body 10 at the same time. . In addition, as shown in FIG. 8, in order to decouple the outer bristles 60 and the inner bristles 80 from the body 10, if only the outer bristles 60 are decoupled from the body 10, even the inner bristles 80 can be spliced with the outer bristles. The 60 is decoupled together such that the outer bristles 60 and the inner bristles 80 can be easily decoupled from the body 60.

In order to use the face cleaning device according to the present invention having the inner bristles on the outer bristles, after the cover 90 is decoupled from the outer bristles 60, the power button 42 of the power supply unit 40 is depressed for supply. The power is supplied to the operation control unit 30 to operate the drive motor 20.

When the drive motor 20 is rotated clockwise or counterclockwise, the power transmission element 50 rotates clockwise or counterclockwise.

The rotational motion of the power transmitting element 50 is transmitted to the inner bristles 80 coupled to the power transmitting element 50, and even causes the inner bristles 80 to rotate counterclockwise or counterclockwise.

When the inner bristles 80 are rotated clockwise or counterclockwise, the outer bristles 60 are fixedly coupled to the body 10 without rotation. Therefore, by the outer bristles 60, even if the inner bristles 80 are rotated to clean foreign matter adhering to the skin of a user, the foreign objects are not splashed.

Thereafter, after the face cleaning device has been used, the outer bristles 60 can be separated from the body 10 for cleaning.

In this example, if only the outer bristles 60 are separated from the body 10, the inner bristles 80 on the outer bristles 60 will be separated from the body 10 together with the outer bristles 60 such that the outer bristles 60 and the inner bristles 80 It can be separated from the outer bristles 60 simply.

Although a face cleaning device having a bristle structure in which the inner bristles are located on the outer bristles has been described in accordance with an embodiment of the present invention for illustrative purposes, the invention is not limited thereto. It will be apparent to those skilled in the art that various modifications, additions and substitutions are possible without departing from the scope of the invention as described below.
