(en)BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a skin care device with multiple functions, more particularly to a skin care device having a plurality of skin care heads individually and detachably combined with the main body of the device, wherein if a skin care head is combined with the main body, the skin care head is instantly recognized by the device and its product identification number and image are simultaneously displayed on a display screen.
2. Description of the Related Art
Human skin starts aging in one's twenties and people's facial appearance looks old with time as well. In particular, the facial skin determines decisively another person's first impression. People guess other people's age by looking at how their skin looks. Therefore, people naturally have made efforts to look younger and more beautiful. At the same time, people have strived to delay the aging of their facial skin.
Skin aging is a natural phenomenon but its speed may differ significantly with external factors. The most representative factors include the effect of active oxygen produced on the skin, and exposure to ultraviolet rays.
Therefore, natural skin aging that comes with age cannot be controlled with human effort, but eliminating or reducing the external factors, for example, the elimination of active oxygen produced on the skin, the protection of ultraviolet rays, or the acceleration of creation of new skin cell may slow down skin aging and make the skin look younger and prettier for one's age.
Active oxygen, one of the skin aging factors, is an oxygen residue of highly oxidative that is produced inside body while inhaled oxygen is metabolized. However, it is also produced when the skin is exposed to ultraviolet rays.
Such active oxygen destroys genetic information of deoxyribonucleic acid (DNA) and collapses cell membrane by attacking normal DNA and cell groups. As a result, abnormal cell protein is created. In particular, since facial skin is more likely to be exposed to ultraviolet rays, active oxygen can be made more frequently. In this process, the fat substance inside the cell membrane of the facial skin is oxidized and thus lipid peroxide is created. When it is combined with protein, senile pigment named lipofuscin is produced, causing senile age spots. It also influences on melanin pigment, creating freckles on the facial skin. Furthermore, it spoils collagen which is skin resilience fiber, leading to sagging or wrinkled skin.
Naturally, a variety of skin care devices have been developed to tackle the problems mentioned above. Those devices include vibration massager, infrared rays treatment apparatus, ultrasonic treatment apparatus and thermotherapy device. They are independently used according to a user's purpose and are beneficial to skin care.
There is a problem, however, that users have to purchase all these products for skin care, which is financially burdensome. What's more, as those devices are quite big it is not convenient to carry or store them, making them not practical.
BRIEF SUMMARY OF THE INVENTION
One of the objectives of the present invention is to solve the problems mentioned above. According to the present invention, a plurality of skin care heads can be individually separated from or combined with the main body of a skin care device, and when a skin care head is combined with the main body, it is immediately recognized by the device and its product identification number and image are simultaneously displayed on a display screen. This skin care device with multi-functions allows users to care their skin effectively through a variety of beneficial functions such as galvanic electric current, ultrasonic vibrations, and near-infrared LED.

DETAILED DESCRIPTION OF THE INVENTION
Some embodiments of the present invention will be described in detail with reference to the accompanying drawings.
In one embodiment, as illustrated in FIGS. 1-4 , a skin care device according to the present invention includes a main body 100 of a cosmetic container shape, the body having a first connecting terminal 310 formed on the upper portion thereof a plurality of skin care heads 200 individually and detachably combined with the upper portion of the main body 100 , the heads 200 each having a second connecting terminal 300 formed on the lower portion thereof, the second connecting terminal 300 electrically being connected with the first connecting terminal 310 ; and a product identification displaying part 120 displaying an identification number of the heads or a relevant image of the heads on a display screen 110 when the first connecting terminal 310 and the second connection terminal 300 are connected each other.
The skin care device has a shape of a usual cosmetic container if the main body 100 is combined with a skin care head 200 . The plurality of skin care heads 200 are individually used with one main body 100 .
In one embodiment, the plurality of skin care heads 200 comprise a first skin care head 210 , a second skin care head 220 , a third skin care head 230 , a fourth skin care head 240 , a fifth skin care head 250 and a sixth skin care head 260 wherein the first skin care head 210 has a galvanic current generator 500 and an ultrasonic vibrator 400 installed therein, and wherein the second skin care head 220 , the third skin care head 230 , the fourth skin care head 240 , the fifth skin care head 250 and the sixth skin care head 260 each have a galvanic current generator 500 , an ultrasonic vibrator 400 and a near-infrared LED 600 installed therein.
The first skin care head 210 , the second skin care head 220 , the third skin care head 230 , the fourth skin care head 240 , the fifth skin care head 250 and the sixth skin care head 260 each are shaped differently. This is because each different shape may bring more effective skin care.
The first skin care head 210 , the second skin care head 220 , the third skin care head 230 , the fourth skin care head 240 , the fifth skin care head 250 , the sixth skin care head 260 , and the negative ion sprayer 700 have a same terminal structure such that each of them works with the first connecting terminal 310 and the second connecting terminal 300 .
Galvanic current generated by the galvanic current generator 500 is direct current which flows constantly at low voltage from the positive pole to the negative pole. If it flows in a certain type of solution that contains acid and salt, chemical reaction occurs. Galvanic current is a direct current ranged from 60 to 80 V and chemically reacts if it passes through the skin containing more than 60 percent of moisture. It is also known that chemical reaction occurs if galvanic current passes through a human body's cell tissue and cell sap. Such galvanic current makes the skin more resilient, expands blood vessels accelerating blood circulation, and stimulates the skin helping to get better nutritious state.
Ultrasonic wave generated from the ultrasonic vibrator 400 is a sound wave that vibrates so quickly that human cannot hear. Its frequency is over 18,000 Hz. This ultrasonic vibration stimulates the skin, resulting in muscle strengthening, resilience increase and acceleration of nutrient provision into cellular tissues.
Near-infrared LED 600 expands blood vessels inside cellular tissues, increasing the blood flow. It also help accelerate cellular division, activate cell, and empower immune cell and has anti-inflammatory function. Thus, it has been used for various disease cure.
The product identification displaying part 120 controlled by a micro-computer 900 is to display product information on the display screen 110 . The micro-computer 900 has each unique number inputted for each skin care head 200 , and according to the each inputted number, the information on a skin care head 200 is displayed on the display screen 110 when the skin care head 200 is connected with the main body 100 .
For example, when setting a unique product number for each skin care head, you can assign ‘1’ for the first skin care head 210 , ‘2’ for the second skin care head 220 , ‘3’ for the third skin care head 230 , ‘4’ for the fourth skin care head 240 , ‘5’ for the fifth skin care head 250 and ‘6’ for the sixth skin care head 260 and input a relevant product image for each skin care head into the micro-computer 900 .
If the second skin care head 220 is combined with the main body 100 , the first connecting terminal 310 and the second connecting terminal 300 are electrically connected each other. In this case, micro-computer 900 recognizes the connection of the second skin care head 220 and displays a relevant product identification and image on the display screen 110 of the product identification displaying part 120 .
In other words, the skin care head 200 works immediately when the skin care head 200 is combined with the main body 100 , while the skin care head is turned off when the skin care head 200 is separated from the main body 100 . Furthermore, a plurality of skin care heads 200 are individually and detachably combined with one main body 100 and thus a specific skin care head may be used selectively according to a user's purpose.
In another embodiment, as illustrated in FIG. 5 , a negative ion sprayer 700 may be combined with the upper portion of the main body, which sprays ultrafine water of negative ion onto a user's face. In still another embodiment, as illustrated in FIG. 6 , the skin care device includes a mask 800 attachable to a user's face and electrically connected to the main body 100 of the device. A conductive clip 810 corresponding to the negative pole is connected to a user's hand and another conductive clip 820 corresponding to the positive pole is connected to the mask 800 .
Because technologies regarding skin care head, negative ion sprayer, and mask are widely used, detailed information on their specific configuration and mechanism will be omitted here.
According the present invention, one of the first skin care head 210 , the second skin care head 220 , the third skin care head 230 , the fourth skin care head 240 , the fifth skin care head 250 or the sixth skin care head 260 may be selectively connected with the main body 100 . For example, the first skin care head 210 may be used for the nose area and the second and the third skin care heads 220 , 230 may be used to remove skin dead cell. For a gentle massage, the fourth skin care head 240 and the fifth skin care head 250 may be used, and the sixth skin care head 260 may be used for the scalp massage.
For example, in order to care the nose area, a user may select the first skin care head 210 among the skin care heads 200 . When the user combines the first skin care head with the upper portion of the main body 100 , the first connecting terminal 310 and the second connecting terminal 300 are connected each other and the first skin care head 210 becomes ready to operate.
Then, micro-computer 900 recognizes that the first skin care head 210 has been connected and displays a product identification information on the display screen 110 of the product identification displaying part 120 . The product identification displaying part 120 displays the number ‘1’ and the relevant image of the first skin care head. A user can now use the device on his skin, and the rest of skin care heads, which are the second skin care head 220 , the third skin care head 230 , the fourth skin care head 240 , the fifth skin care head 250 or the sixth skin care head 260 , can be selectively used after connecting with the main body 100 according to the user's purpose.
Because the skin care heads each have galvanic current generator 500 and ultrasonic vibrator 400 or galvanic current generator 500 , ultrasonic vibrator 400 and near-infrared LED 600 built therein, more effective skin care can be made.
Meanwhile, if a user combines the negative ion sprayer 700 with the upper portion of the main body 100 , the negative ion sprayer 700 sprays ultrafine water of negative ion onto the user's face and helps keep the skin hydrated.
When using the mask 800 , after having it electrically connected with main body 100 , a conductive clip corresponding to the negative pole (−) is connected to a user's hand while a conductive clip corresponding to the positive pole (+) is connected with a mask. If a user applies the mask on his face, the nutritional contents of cosmetics applied on the facial skin will be easily absorbed into the skin.
