Description

Skin care device

The present invention relates to a skin care device, and more particularly, to a skin care device capable of stimulating the skin through ultrasonic vibrations to discharge waste products inherent to the outside and to improve blood circulation.

Recently, a skin massager capable of massaging and cleansing facial skin using ultrasonic vibrations and treating obesity in the abdomen has been developed and used.

The skin massager stimulates the skin by transmitting ultrasonic vibrations to the skin, thereby discharging waste products contained in the skin to the outside of the skin and helping the blood circulation to be made smoothly. Such a skin massager is usually provided with an ultrasonic generating member capable of generating ultrasonic vibrations, and has a vibration transmitting member for transmitting ultrasonic vibrations from the ultrasonic generating member to the skin.

Such a skin massager is disclosed in Korea Utility Model Model No. 20-0173224 (registration date: December 17, 1999). The skin massager is used in a state in which the cap for pressure on the ultrasonic vibrator. In this case, the cap for shiatsu is formed with a plurality of small size projections for shiatsu on the front.

By the way, the skin massager uses the acupressure cap with the ultrasonic vibrator, so the ultrasonic vibrator and the acupressure cap are not integrated with each other, so the ultrasonic vibration generated from the ultrasonic vibrator is not properly transmitted to the acupressure cap and massaged. There is a problem that the effect is significantly lowered.

In addition, the skin massager was difficult to keep the skin massager clean because it is difficult to wash the ultrasonic vibrator with water after using the ultrasonic vibrator to directly massage the skin without the cap for acupressure. This is because the ultrasonic vibrator is formed integrally with the skin massager because water is introduced into the skin massager having various electronic devices vulnerable to water when washed with water.

In addition, a plurality of roughly hemispherical protrusions formed on the cap for acupressure are not advantageous for removing the wastes inherent in the skin, and thus, the effect of removing the skin wastes was also insignificant.

Hereinafter, with reference to the accompanying drawings will be described a skin care device according to an embodiment of the present invention. However, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

Referring to Figure 1, the skin care device 10 according to an embodiment of the present invention includes a charging table 100 and a massage device 200.

Referring to FIG. 2, the charging table 100 may seat the massage device 200, and a connection port (not shown) to which an external power terminal is connected may be provided at a portion thereof. As the connection port, for example, a standard standard such as a USB port is applied.

Mounting portion 251 is pivotal movement is possible as the rear end is connected to the normal hinge inside the one end 230 of the body portion (210). When the skin massage is performed while the vibration module 270 is mounted on the mounting unit 251, the position of the vibration module 270 may be naturally changed according to the bending of the body.

In this case, the mounting portion 251 is hinged, and is elastically supported by the one end portion 230 by a predetermined elastic member (for example, a coil spring) so as not to massage the skin of the vibration module 270. The position can be returned to the original position.

In addition, the mounting portion 251 is formed with a plurality of terminals (215a, 215b, 215c) for projecting the power to the vibration module 270.

Among the first to

third terminals

215a, 215b, and 215c, the first and

second terminals

215a and 215b are positive electrodes, and the third terminal 215c is a negative electrode. In this case, the first and

second terminals

215a and 215b, which are anodes, are provided to oscillate the corresponding vibration frequencies (first and second vibration frequencies) with respect to the vibration module 270 mounted on the mounting portion 251. For example, the vibration module having the first vibration frequency mounted on the mounting portion 251 has two terminals connected to the first terminal 215a and the third terminal 215c, and has a vibration module having the second vibration frequency. Has two terminals connected to the second terminal 215b and the third terminal 215c.

Therefore, the user may selectively mount the vibration module 270 to the mounting unit 251 according to the intensity of vibration during skin massage.

In the mounting portion 251, the

first magnets

214a, 214b, 214c, and 214d are disposed in the plurality of recesses formed in the mounting surface 251c, respectively. The plurality of

first magnets

214a, 214b, 214c, and 214d are attached to each other by a plurality of

second magnets

274a, 274b, 274c, 274d (see FIG. 7) provided in the vibration module 270. Accordingly, the user can easily mount and detach the vibration module 270 to the mounting unit 251.

The plurality of

first magnets

214a, 214b, 214c, and 214d may be positioned at positions corresponding to each corner of the virtual rectangle so that magnetic force is uniformly distributed on the mounting surface 251c of the mounting unit 251.

5 to 9, the vibration module 270 includes a base member 271, a skin contact member 273, a buffer 277, and an ultrasonic wave generator 278.

The base member 271 has a substantially circular coupling rib 271a protruding from the rear, and a portion of the circular coupling rib 271a is formed with a slit 271b. The slit 271b has a guide rib 251b formed in the circular coupling groove 251a of the mounting portion 251. The position of the slit 271b and the guide rib 251b is set in consideration of the mutual attachment position between the plurality of first and

second magnets

214a, 214b, 214c and 214d; 274a, 274b, 274c and 274d.

In the base member 271, fourth to

sixth terminals

275a, 275b, and 275c to which the first to

third terminals

215a, 215b, and 215c are connected are disposed on the rear surface 271c. In this case, the fourth to

sixth terminals

275a, 275b, and 275c are formed on the rear surface 271c so as to make an accurate connection with the first to

third terminals

215a, 215b, and 215c protruding from the mounting surface 251c. It is arranged in the groove.

The plurality of

second magnets

274a, 274b, 274c, and 274d protrude from the rear surface 271c by a predetermined length. Accordingly, when the vibration module 270 is mounted on the mounting unit 251, the

first magnets

214a, 214b, 214c, and 214d are guided along a plurality of recesses in which the plurality of

first magnets

214a, 214b, 214c, and 214d are disposed. , 214c, 214d).

Accordingly, the vibration module 270 is firmly mounted to the mounting portion 251 by a magnetic force acting between the plurality of first and

second magnets

214a, 214b, 214c, 214d; 274a, 274b, 274c, 274d. The operation of detaching from 251 can also be made simply.

The back skin contact member 273 is coupled to the front of the base member 271. The skin contact member 273 is made of a metal material and is integrally formed with a skin contact protrusion 273a in front of the skin.

The skin contact protrusion 273a is formed of a plurality of tubular shapes (for example, substantially cylindrical) overlapping concentric circles and protrudes at a predetermined height toward the front of the skin contact member 273. The tip of the skin contact protrusion 273a serves to transmit ultrasonic vibrations in contact with the skin.

The height of the skin contact protrusion 273a is that the skin, which is located inside the skin contact protrusion 273a when the pressure is applied to the skin at a predetermined pressure while the tip of the skin contact protrusion 273a is in contact with the skin, is a skin contact member 273. It is enough if it does not reach the front (273b) of). This is to place a predetermined space (S) so that the pores are not blocked by the front surface (273b) when the wastes inherent in the skin is discharged to the outside of the skin through the pores. Accordingly, the wastes inherent in the skin may be naturally discharged through the pores of the skin by ultrasonic vibration.

In addition, since the skin contact protrusion 273a having a cylindrical shape exhibits excellent resonance characteristics when the ultrasonic vibration is transferred, the skin contact protrusion 273a may effectively massage the skin through the ultrasonic vibration even with a single ultrasonic generator 278.

The shock absorbing portion 277 is a ring-shaped member disposed on the outer circumferential surface of the base member 271. Referring to FIG. 9, the buffer part 277 according to the first embodiment of the present invention is made of a low-rigid elastic body such as rubber, etc., and has one side of the first ring member 277a and the first ring member 277a. And a second ring member 277b spaced apart in the direction. A portion of one side of the first ring member 277a and a portion of one side of the second ring member 277b are integrally formed by the coupling portion 277c.

In addition, the buffer portion 277 is disposed between the inner circumferential surface of the skin contact member 273 and the outer circumferential surface of the base member 271 so as to be spaced between the inner circumferential surface of the skin contact member 273 and the outer circumferential surface of the base member 271 at a predetermined interval. Spaced apart and accommodated in a single groove 271e formed in the outer circumferential portion of the base member 271.

The outer ring portion of the first ring member 277a is accommodated in the groove 273e formed in the inner circumference of the skin contact member 273 so that the inner circumferential surface of the skin contact member 273 is spaced apart from the outer circumferential surface of the base member 271 at a predetermined interval. Support elastically. Accordingly, the first ring member 277a maintains the watertight between the skin contact member 273 and the base member 271 and prevents the skin contact member 273 from being separated from the base member 271.

The outer circumferential portion of the second ring member 277b is not accommodated in the groove unlike the first ring member 277a. When the skin contact member 273 moves toward the base member 271 and engages with the base member 271, the second ring member 277b made of a low-hardness elastic member has an outer circumference portion of the inner circumferential surface of the skin contact member 273. It is bent to the 1st ring member 277a side by pressurization. Accordingly, the second ring member 277b elastically supports the inner circumferential surface of the skin contact member 273 while being spaced apart from the outer circumferential surface of the base member 271 at a predetermined interval while the outer circumferential portion is bent.

As the outer ring portion is bent, the second ring member 277b may vibrate more than the first ring member 277a because the deformation caused by the vibration of the skin contact member 273 may be greater than that of the first ring member 277a. The larger the deformation to absorb more vibration of the skin contact member (273). In addition, since the outer circumferential portion of the second ring member 277b is accommodated in the groove of the skin contact member 273 and does not restrain the skin contact member 273, the skin contact member 273 is the base member compared to the first ring member 277a. Vibrations from 271 are relatively varied. Accordingly, the second ring member 277b more effectively blocks the vibration transmitted from the ultrasonic generator 278 to the skin contact member 273 to the base member 271 than the first ring member 277a. . This is to effectively transmit the ultrasonic vibration to the skin by minimizing the amplitude of the ultrasonic vibration transmitted from the ultrasonic generator 278 to the skin contact member 273 by the base member 271. As described above, the second ring member 277b has an independent movement function that is differentiated from the first ring member 277a as it is not accommodated in the groove.

The ultrasonic generator 278 includes a piezoelectric element 278a and an oscillator 278b disposed in a space formed between the base member 271 and the skin contact member 273. The back surface 273c of the skin contact member 273 is formed in a plane so as to be in close contact with one surface of the piezoelectric element 278a. In this case, the vibration generated by the ultrasonic generator 278 is directly transmitted to the skin contact protrusion 273a.

The piezoelectric element 278a is formed in a donut shape with a hole H formed at the center thereof, and thus, when voltage is applied, the piezoelectric element 278a is elastically deformed in the outer direction of the piezoelectric element 278a and in the inner direction of the hole H. You can increase the intensity.

The oscillator 278b is in close contact with the rear surface of the piezoelectric element 278a and oscillates when power is supplied through the fourth to

sixth terminals

275a, 275b, and 275c.

Hereinafter, with reference to FIGS. 10 to 13, in the example of the buffer unit according to another embodiment, a detailed description of the same configuration as that of the first embodiment will be omitted. A buffer unit according to an example will be described.

Referring to FIG. 10, the buffer 377 according to the second embodiment will be described.

In the buffer part 377 according to the second embodiment, the first recess is formed to be spaced apart from each other, unlike the buffer part 277 according to the first embodiment is accommodated in a single recess 271e formed in the base member 271. 271 g and 2nd groove 271 h, respectively,

The first ring member 377a is accommodated in the groove 273e formed in the inner circumferential portion of the skin contact member 273, and the inner circumferential portion is received in the first groove 271g formed in the outer circumferential portion of the base member 271. The second ring member 377b has an outer circumferential portion elastically supporting the inner circumferential surface of the skin contact member 273, and the inner circumferential portion is accommodated in the second groove 271h formed in the outer circumferential portion of the base member 271. The engaging portion 377c is in surface contact with the inner circumferential surface 271f of the base member 271 formed between the first and

second grooves

271g and 271f. In this case, the second groove 271h may be deeply formed to lower the elastic modulus of the second ring member so that the second ring member 377b may absorb more vibration transmitted from the skin contact member 273.

Referring to FIG. 11, the buffer unit 477 according to the third embodiment will be described with reference to a configuration distinguishing it from the second embodiment.

The buffer part 477 has an outer circumferential surface of the coupling part 477c forming the same surface as the outer circumferential surface of the second ring member 477b to not only make surface contact with the inner circumferential surface of the skin contact member 273, but also the inner circumferential surface of the coupling part 477. Since the surface is in contact with the outer circumferential surface of the base member 271, the watertightness between the skin contact member 273 and the base member 271 is more firmly maintained.

Referring to FIG. 12, the shock absorbing portion 577 according to the fourth embodiment will be described with reference to a configuration distinguishing from the second embodiment.

The shock absorbing portion 577 includes a second ring member 577b disposed separately from the first ring member 577a. The second ring member 577b is made of a material having a lower hardness than the first ring member 577a. Accordingly, the skin contact member 273 is elastically supported by the second ring member 577b having a relatively low hardness around the first ring member 577a having a relatively high rigidity and relatively from the base member 271. It can vibrate freely.

Referring to FIG. 13, the buffer unit 677 according to the fifth embodiment will be described with reference to a configuration distinguishing from the fourth embodiment.

Cross sections of the first and

second ring members

677a and 677b of the shock absorbing portion 677 are formed in an elliptical shape. Accordingly, the cross-sectional area of the first and

second ring members

677a and 677b decreases toward the inner and outer circumferential surfaces thereof, so that deformation due to pressure is easy, so that the skin contact member 273 is larger than the buffer portion 577 of the fourth embodiment having a rectangular cross section. ) Can be elastically supported.

In the skin care device according to the embodiment of the present invention configured as described above, the vibration module 270 includes the base member 271, the skin contact member 273, the shock absorber 277, and the ultrasonic generator 278 as a single module. As a result, the ultrasonic vibration generated from the ultrasonic generator 278 can be effectively transmitted to the skin contact protrusion 273a, and even when washed with water, water does not flow into the vibration module 270. . Furthermore, as the coupling between the vibration module 270 and the mounting portion 251 is made using magnetic force, the vibration module 270 can be easily attached and detached, and the vibration module 270 is firmly attached to the mounting portion 251 when mounted. Can be attached.

Hereinafter, an example in which the skin contact protrusion 273a is formed in various shapes other than a cylinder will be described with reference to FIGS. 14 to 18.

skin contact protrusions

373a and 373b is disposed in the center, and the plurality of skin contact protrusions 373b are approximately circumferentially around the skin contact protrusions 373a. Distributed along the way. Even in this case, the plurality of

skin contact protrusions

373a and 373b are spaced apart from each other to form a predetermined space between the

skin contact protrusions

373a and 373b. Thus, wastes inherent in the skin by ultrasonic vibration are naturally formed by such spaces. May be discharged outside the skin.

Referring to FIG. 15, the plurality of

skin contact protrusions

473a and 473b may have an approximately elliptical shape and overlap each other. In this case, each of the

skin contact protrusions

473a and 473b is curved to have one end portions R1 and R2 in contact with the skin having a predetermined curvature. In this case, the plurality of

skin contact protrusions

473a and 473b may be massaged in close contact with the curvature of the skin.

Referring to FIG. 16, the single skin contact protrusion 573a has a substantially long hole shape, and is curved so that one end portion R3 in the longitudinal direction is recessed at a predetermined curvature.

Referring to FIG. 17, the plurality of

skin contact protrusions

Referring to FIG. 18, the plurality of

skin contact protrusions
