Facial cleaning device having a brush structure in which an outer brush and an inner brush are detachable together

Abstract

The present invention relates to a facial cleansing device having a brush structure in which an outer brush and an inner brush are detachable together, and more particularly to a facial cleansing device having a brush structure in which an outer brush and an inner brush are detachable together, wherein the outer brush Connected to the brush holder and installed in the installation space of the front body of the facial cleansing device, the inner brush is assembled inside the outer brush and connected to the drive motor so that when the inner brush cleans the skin while being vibrated by the drive motor, it is fixed in the The outer brush in the installation space of the front body can prevent water from splashing in various directions due to the centrifugal force generated by the rotation of the inner brush. Furthermore, the present invention relates to a facial cleansing device having a brush structure in which an outer brush and an inner brush are assembled together, wherein the inner brush is assembled between the outer brush and the brush holder and thus located inside the outer brush so that when compared to When the main body disassembles the inner brush and the outer brush, the inner brush and the outer brush can be disassembled together, so that the inner brush and the outer brush can be easily disassembled. In addition, the present invention relates to a face cleaning device having a brush structure in which an outer brush and an inner brush are detachable together, wherein the face cleaning device has a power transmission part provided between the inner brush and the driving motor to connect the inner brush with the driving motor. The motor, thereby preventing the motor shaft from idling when the groove in which the motor shaft is fitted is worn due to the rotation of the motor shaft due to long-term use of the facial cleansing device. The present invention provides a face cleaning device with a brush structure that allows the outer brush and the inner brush to be disassembled together. An installation space (12) is formed inside; a drive motor (20), which is installed in the main body (10) and rotates clockwise and counterclockwise repeatedly; an operation control unit (30), which controls the operation of the drive motor (20); A power supply unit (40), which supplies power to the operation control unit (30); a power transmission part (50), which is located in the installation space (12) of the main body (10) and connected to the drive motor (20); the outer brush ( 60), which is installed in the installation space (12) of the main body (10), and has a first hollow part (61) formed at its center; a brush holder (70), which is connected to the lower part of the outer brush (60) , and has a second hollow portion (72); and an inner brush (80), which is inserted between the outer brush (60) and the brush holder (70), and connected to the power transmission member (50), wherein, the outer brush ( The inside of the first hollow part (61) of 60) is formed with a stop protrusion (62), and the inner brush (80) is formed with an annular edge protrusion (81) on its outer peripheral surface.

Description

technical field [0001] The present invention relates to a facial cleansing device having a brush structure with an inner brush positioned over an outer brush. More specifically, the present invention relates to a face cleansing device having a brush structure in which an inner brush is placed on an outer brush, wherein the outer brush is connected to a brush holder and installed in an installation space of a front body of the face cleansing device, and The inner brush is assembled inside the outer brush and combined with the drive motor so that when the inner brush cleans the skin while being vibrated by the drive motor, the outer brush fixed in the installation space of the front body can prevent water from being generated by the rotation of the inner brush The centrifugal force splashes in all directions. [0002] Furthermore, the present invention relates to a facial cleansing device having a brush structure in which an inner brush is placed on an outer brush, wherein the ...
