When the coupling part 100 of the glass brush 8 is inserted into the holder 60 and inserted into the holder 60, the brush bracket 132 of the glass brush 8 may cover a portion between the ultrasonic head 20 and the first case 30, and the ultrasonic head shielding part 133 may shield the ultrasonic head 20 from the lower side of the ultrasonic head 20 and protect the ultrasonic head 20.
A plurality of groove parts or hole parts may be formed in the glass 134, and the plurality of groove parts or hole parts may be finely formed in the glass 134 by etching. The glass 134 may be a friction plate or a friction pad having a high surface roughness due to a plurality of groove parts or hole parts.
As described above, when the glass brush 8 is rotated, the glass brush may rub against the skin to remove wastes or dead skin cells.
The glass 134 may be a friction plate having a large surface roughness, and when the glass 134 is rotated, it is possible to effectively remove dead skin cells from the user's heel.
The plurality of brush units 6, 7, and 8 may have the same formation position of the coupling part 100. The coupling parts 100 of the plurality of brush units 6, 7, and 8 may have the same size and shape.
The coupling part 100 of each of the plurality of brush units 6, 7, and 8 may be selectively inserted into the gap T.
The plurality of brush units 6, 7, and 8 may have different types of magnets M1, M2, and M3.
For example, the magnet M1 mounted on the brush bracket 112 of the cleaning brush 6 has an S pole magnetic force, and the magnet M2 mounted on the brush bracket 122 of the regular bristle brush 7 has a magnetic force in which a S pole and an N pole are mixed, and the magnet M3 mounted on the brush bracket 132 of the glass brush 8 may have an N pole magnetic force.
The sensor 90 illustrated in
The body cleanser 1 may include a controller 100.
The controller 150 may control the overall operation of the body cleanser 1 and may include a microcomputer 102, an ultrasonic controller 104, a vibration motor controller 106, and a rotation motor controller 108.
The controller 150 may recognize the brush units 6, 7, and 8 mounted on the holder 60 according to the sensed value of the sensor 90, and can control the body cleanser 1, in particular, the ultrasonic vibrator 22, the vibration motor 80, and the rotation motor 73.
The microcomputer 102 may recognize which of the plurality of brush units 6, 7, and 8 is mounted according to a signal output from the sensor 90.
The microcomputer 102 may output a signal to the ultrasonic controller 104, the vibration motor controller 106, and the rotation motor controller 108 according to the recognition result.
An example of the ultrasonic controller 104 may be a circuit part capable of outputting a control signal of the ultrasonic vibrator 22 to the ultrasonic vibrator 22.
An example of the vibration motor controller 106 may be a circuit part capable of outputting a control signal of the vibration motor 80 to the vibration motor 80.
An example of the rotation motor controller 108 may be a circuit part capable of outputting a control signal of the rotation motor 73 to the rotation motor 73.
The controller 150 may operate the vibration motor 80 and the ultrasonic vibrator 22 when the cleaning brush 6 is mounted. In this case, the silicone brush 114 of the cleaning brush 6 can apply vibration and ultrasonic waves to the skin, and the user can deep clean the skin.
The controller 150 may operate the rotation motor 73 of the rotation mechanism 70 when the regular bristle brush 7 or the glass brush 8 is mounted. When the regular bristle brush 7 is mounted, the fine bristle brush 124 can be rotated to cleanly clean the user's elbows or the like.
When the glass brush 8 is mounted, the glass brush 8 can be rotated to remove dead skin cells from the user's heel.
The controller 150 may drive the rotation motor 73 for a first set time when the regular bristle brush 7 is mounted, and the controller may drive the rotation motor 73 for a second set time when the glass brush 8 is mounted, and the second set time may be longer than the first set time.
The above-disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other implementations, which fall within the scope of the present disclosure.
Thus, the implementation of the present disclosure is to be considered illustrative, and not restrictive.
Therefore, the scope of the present disclosure is defined not by the detailed description of the invention but by the appended claims, and all differences within the scope will be construed as being included in the present disclosure.
