Description

{A device that modulates ultrasonic frequency to increase skin lifting and skin elasticity}

The present invention relates to a massage device that emits vibration, ultrasonic waves, and far infrared rays.

More specifically, the skin beauty effect can be maximized by emitting ultrasonic waves with a wavelength similar to the physiological frequency to the skin by an ultrasonic oscillator, and the oscillator is installed on the bottom of the amethyst, making it human-friendly by amethyst with regular waves. By emitting far-infrared rays from the far-infrared ray generator to the skin, the rhythm of the body can be stabilized.

In addition, it relates to a skin massage device in which the hand grip feeling is improved when used by improving the shape and structure of the case that constitutes the exterior of the massage device.

The skin is the human body's primary defense shield and has the unique function of protecting internal organs from external environmental stimuli such as temperature and humidity changes, ultraviolet rays, and pollutants. In addition, as we age, the secretion of various hormones that internally regulate metabolism decreases, the function of immune cells and the activity of cells decrease, and the biosynthesis of immune proteins and biocomponent proteins necessary for the living body decreases.

Moreover, in recent years, the skin is easily exposed to ultraviolet rays due to the destruction of the ozone layer, and as environmental pollution becomes more severe, physical and chemical stimulation and stress destabilize the skin and cause a breakdown in skin homeostasis. Skin with reduced homeostasis Its own rhythm is disrupted, and various skin problems such as dryness, loss of elasticity, pigmentation, and imbalanced secretion of sebum occur.

Accordingly, in order to improve the health of the skin, efforts are made to protect the skin by undergoing surgery to physically remove wrinkles, using skin care cosmetics, or using a skin massager.

As one of the prior technologies related to this, a hand peeling machine for both massage and massage was described in Registered Utility Model Publication No. 20-0414870. Figure 1 shows a hand peeling machine for both massage and massage.

It is a front view, Figure 6 is a plan view showing the combined state of the skin massage tool and the holder according to the present invention, and Figure 7 shows an enlarged cross-sectional view of the head part of the present invention.

The skin massage device according to an embodiment of the present invention includes an amethyst 10, a coupling ring 20, a bracket 30, a heating unit 40, a vibration unit 50, an ultrasonic wave generator 60, and a case 70. It is composed including.

Amethyst 10 performs the function of emitting far-infrared rays to the skin, and as shown in the attached drawing, it may be formed in a cylindrical shape, and a groove 11 may be formed on the outer bottom surface.

The surface of the amethyst 10 that comes into contact with the skin is formed in a round and convex shape so that it can easily come into contact with the skin. That is, when it comes into contact with a body part with a thick epidermal layer, such as the thigh, the amethyst 10 comes into contact with the amethyst 10. Due to the elasticity of the skin, the entire cross section of the amethyst (10) comes into contact with the skin, and even in body parts such as the forehead where the epidermal layer is thin and has little elasticity, the entire cross section of the amethyst (10) comes into contact with the skin, making the amethyst (10) It minimizes the loss of vibration, ultrasonic waves, far-infrared rays, and heat emitted through and ensures efficient delivery to the skin.

Meanwhile, crystals come in various colors, including colorless, purple, yellow, brown, red, green, blue, and black. In particular, purple crystals are called amethyst. At this time, the color range of amethyst is very wide, ranging from colorless light purple to deep purple.

Amethyst (SiO2) has a density of 2.65 and hardness of 7, and is a hexagonal mineral (tectosilicate, quartz, iron oxide) that emits far-infrared rays that are beneficial to the human body.

Far-infrared rays promote the growth of plants and animals, activate water, maintain the freshness of plants, increase taste, deodorize and ripen. The effects on the human body include increasing the temperature of the deep subcutaneous layer, expanding microvascular vessels, promoting blood circulation, and improving metabolism. It is shown to strengthen and increase tissue regeneration ability, and its excellent effect is recognized for gynecological diseases, nervous system diseases, and geriatric diseases. In addition, living organisms are mostly made up of water and protein, and the vibration wavelength of the molecular motion of organic compounds that make up water or protein is high. If the wavelength range of the irradiated far-infrared rays is the same, the molecular movement is activated.

In addition, it has a warming and sweating effect by generating self-heating by far-infrared rays penetrating into the body, promotes metabolism, improves blood circulation, revives the production of enzymes, and activates aged cells to remove waste products and excess fat. It promotes excretion and suppresses the production of lactic acid, free fatty acids, fatty acid esters, cholesterol, excess salt, and uric acid, which are causes of fatigue and aging.

Therefore, the skin massage device according to the present invention is provided with an amethyst 10, a heating unit 40, and an ultrasonic generator 60 to provide heat,

The coupling ring 20 has a protrusion 21 formed in the longitudinal direction on one side, and the protrusion 21 is installed by fitting into the groove 11 formed on the bottom outer surface of the amethyst 10. The bracket 30, which will be described later, ) to ensure that the amethyst (10) and the bracket (30) are firmly coupled.

At this time, the coupling ring 20 may be made of a silicon material. This coupling ring 20 may be manufactured in a ring shape with a certain width. However, at this time, if the coupling ring 20 is manufactured in a ring shape, It is difficult to install the protrusion 21 into the groove 11 of the amethyst 10.

Therefore, a portion of the coupling ring 20 can be cut and installed to engage the groove 11 of the amethyst 10 by the elasticity of the coupling ring 20 itself. Additionally, the coupling ring 20 extends lower than the bottom of the amethyst 10. Depending on the design conditions, an O-ring 22 may be interposed between the coupling ring 20 and the amethyst 10. This O-ring 22 connects the amethyst 10 and the coupling ring 20.

In other words, 3Mhz ultrasonic waves move quickly and are converted into heat quickly, so 3Mhz has an inherent limitation of being used weakly, so it is mainly used for facial beauty.

Therefore, 1Mhz is suitable for thick epidermal layers such as the abdomen or thighs, and 3Mhz is suitable for thin epidermal layers such as the face.

The vibrator 53 emits vibrations of 50 to 200 hz, and is selectively emitted by manipulating the button 72, which is connected to the control unit 71 and transmits an electrical signal.

Here, the ultrasonic vibrator 51 may be installed in contact with the amethyst 10 at the center of the donut-shaped heating part 40.

At least one vibrator 53 may be installed in contact with the amethyst 10 between the ultrasonic vibrator 51 and the heating unit 40. The vibrator 53 may be a vibration motor, a solenoid, or a piezo. ) It can be formed as either an element or a linear vibrator. The ultrasonic wave generator 60 is installed at the bottom of the bracket 30 and is located in the space between the heating unit 40 and the vibrating unit 50.
