Beauty device

A beauty device, comprising:

• a main body;
• and
• a head module detachable from the main body,
• wherein the head module includes at least one of a plurality of protrusions, a light-emitting part, an electrode part, a sensor, and a motor,
• wherein the sensor includes a proximity sensor,
• wherein the light-emitting part includes:
• a first light-emitting part disposed between a first virtual circle and a second virtual circle having a circumference less than a circumference of the first virtual circle,
• a second light-emitting part disposed along a third virtual circle having a circumference less than the circumference of the second virtual circle, and
• a third light-emitting part disposed inside the third virtual circle,
• wherein one of the first, second and third light-emitting parts is a laser module having a convex lens configured to compensate for a narrow collimated beam characteristic of laser light by diverging the laser beam to achieve even distribution across a scalp,
• wherein the others of the first, second and third light-emitting parts are an LED module having a flat lens configured to maintain a natural wide-angle emission characteristic of LED light for efficient area coverage,
• wherein the plurality of protrusions are disposed along the first, second and third virtual circles,
• wherein the electrode part and the sensor are disposed inside the third virtual circle,
• wherein the sensor is disposed closer to a center portion of the head module than to an outer circumference of the head module to minimize false detection caused by accidental covering of peripheral areas,
• wherein the light-emitting part, the electrode part, and the motor are configured to operate when the proximity sensor detects an object within a predetermined distance, and
• wherein an area occupied by the plurality of protrusions in a base of the head module is larger than an area occupied by the light-emitting part in the base, such that the plurality of protrusions are configured to displace hair to minimize interference with light transmission from the light-emitting part while simultaneously providing massage effects.
