Technical Field

[0001] The present disclosure relates to a beauty device. Background Art

[0002] Generally, in order to provide nutrition by allowing the active ingredients of cosmetics to penetrate deep into the skin, a makeup method is used in which the active ingredients of the cosmetics applied to the skin are patted or rubbed by hand. Recently, an iontophoresis function, an ultrasonic function, or a massager having a cold and hot function is used.

[0003] As an example of a conventional massager, a composite beauty device is disclosed in Korean Patent Publication KR 10-2017-0098577A1 (published on August 30, 2017).

[0004] The composite beauty device includes: a main body having a base body provided with a plurality of ventilation holes, an upper cover coupled to the base body, and a head detachably coupled to the upper cover and contacting the user's skin to supply ions; a thermoelectric element unit coupled to the main body and radiating hot air or cold air to the skin through the head; a heat dissipation unit provided in the base body and configured to dissipate heat from the thermoelectric element unit by introducing external air through the plurality of ventilation holes; an ultrasonic generator provided on the head to generate ultrasonic waves; and a vibrator provided on the upper cover for vibrating the head. Summary of the Invention

[0005] Technical Problem

[0006] An object of the present disclosure is to provide a beauty device that can minimize the penetration of moisture into the beauty device.

[0007] Technical Solution

[0008] A beauty device according to the present embodiment may include: an ultrasonic vibrator configured to generate ultrasonic waves; an inner electrode having a space for receiving the ultrasonic vibrator; a window configured to be provided outside the outer periphery of the inner electrode; an LED PCB configured to be provided behind the window and having an LED provided thereon; and an outer electrode configured to be provided on the window and spaced apart from the inner electrode.

[0009] The inner electrode may include: a precursor in which the ultrasonic vibrator is provided on the rear surface; and a hollow body protruding rearward from the outer periphery of the precursor and having the space formed therein.

[0010] In the beauty device, an inner waterproof ring may be provided between the hollow body and the window.

[0011] A groove facing the window may be formed on the outer peripheral surface of the hollow body.

[0012] The inner waterproof ring can be received in the groove.

[0013] The beauty device may further include a heater configured to be disposed on a rear surface of the front body.

[0014] The heater may further include: a film; a heating element formed on the film; and a temperature sensor disposed on the film.

[0015] The window may include a rear protrusion surrounding an outer periphery of the hollow body.

[0016] The LED PCB can be received between the hollow body and the rear protrusion.

[0017] The beauty device may further include a front cover having an electrode connection portion to which the inner electrode is connected, and a window receiving portion in which a part of the window is received.

[0018] An outer waterproof ring may be provided between the window receiving portion and the window.

[0019] The outer electrode may include a rear protrusion that is inserted between the window receiving portion and the window and is disposed in front of the outer waterproof ring.

[0020] The beauty device may further include: a head PCB to which each of the inner electrode and the outer electrode is connected; and an eye care member configured to be connected to the head PCB.

[0021] The beauty device may further include a front cover formed with a penetration portion through which the eye care member passes.

[0022] In the eye care member, an eye care waterproof ring may be provided to form a seal between the penetration portion and the eye care member.

[0023] The eye care member may include: a ball exposed to an outside of the front cover; and a terminal protruding from the ball and penetrating the penetration portion.

[0024] The eye care waterproof ring may be received in the groove formed in the terminal and may contact the penetration portion.

[0025] Advantageous Effects

[0026] According to an embodiment of the present disclosure, the inner waterproof ring forms a seal between the hollow body of the inner electrode and the window, thereby minimizing the penetration of moisture through a gap between the inner electrode and the window.

[0027] In addition, the inner waterproof ring is received in a groove formed on the outer peripheral surface of the hollow body, so that the inner waterproof ring can be hidden between the inner electrode and the window, making the appearance of the beauty device simple and concise.

[0028] In addition, since the heater provided on the rear surface of the front body can raise the temperature of the front body, the contact between the cold front body and the user's skin can be minimized.

[0029] In addition, the rear protrusion of the window can protect the hollow body of the inner electrode and the LED PCB.

[0030] In addition, the LED PCB is received between the hollow body and the rear protrusion, so that the beauty device can be made as compact as possible.

[0031] In addition, the outer waterproof ring forms a seal between the window receiving portion of the front cover and the window, thereby minimizing the penetration of moisture through the gap between the front cover and the window.

[0032] In addition, the rear protrusion of the outer electrode can hold the outer waterproof ring provided between the window receiving portion and the window in place between the window receiving portion and the window, and can restrict any removal of the outer waterproof ring.

[0033] In addition, since the rear protrusion of the outer electrode covers the outer waterproof ring, the appearance of the beauty device is made simple and concise.

[0034] In addition, the eye care waterproof ring forms a seal between the eye care member and the front cover,

[0035] Therefore, the penetration of moisture through the gap between the eye care member and the front cover can be minimized.

[0036] In addition, the eye care waterproof ring is hidden in the front cover, so that the appearance of the beauty device is made simple and concise. BRIEF DESCRIPTION OF THE DRAWINGS
