About.

Recently, as the standard of living has improved and many people have been thinking about the quality of life, the desire to become younger and more beautiful has been increased, and accordingly, a lot of attention has been paid to skin beauty. In particular, as a lot of interest in facial skin beauty has been developed, various equipment for managing facial skin beauty has been developed and commercialized.

Skin beauty equipment mainly uses low-power laser light or LED light, and low-power light is absorbed by the mitochondria, the energy power plant of skin cells, and helps to increase'fibroblasts' in the dermal layer that makes up the fibers that make up the skin. It is known to be. Fibroblasts help the skin's elasticity and regeneration, so when fibroblasts increase, the skin condition naturally improves.

Light appears differently in color depending on the wavelength band, and the effect on the skin varies according to the wavelength band.For example, a blue light source is absorbed in less than 1mm of the skin and is effective in destroying bacteria that cause acne. The green light source is said to help improve wrinkles by stimulating the skin's metabolism. The red light source, which is most commonly used, penetrates to the dermal tissue to help cell generation, is effective in skin elasticity and regeneration, and near-infrared rays are known to help prevent skin pigmentation by penetrating to a depth of 4 mm.

Such skin care equipment has been used in a specialized hospital that manages the skin, but in recent years, there is a trend of miniaturization so that general users can easily use it even at home.

It can be assembled by passing through, and the operation hole 15 is formed long in a direction in which the support pillar 20 rotates around a horizontal axis.

The left and right rotation means is for driving the support column 20 to rotate in the left and right directions about the horizontal axis with respect to the lower support 10, and is fixedly installed in the first rotation support 13 and installed on the control board 40. It consists of a first electric motor 51 that is driven by the control, and a rotating plate 52 fixed to the motor shaft of the first electric motor 51 and fixed with a fixing means such as a second rotation support 14 and screws.

Accordingly, the rotational force of the first electric motor 51 is transmitted to the support pillar 20 through the rotary plate 52 and the second rotary support 14 so that the support pillar 20 rotates left and right.

On the other hand, the support pillar 20 is formed separately into a cylindrical lower pillar 21 and an upper pillar 22, and the upper pillar 22 is inserted and installed in the lower pillar 21, and the lower pillar ( It is possible to adjust the height of the head part 30 by moving the upper column 22 in the upper and lower directions with respect to 21).

The head unit 30 is provided with a head body 31 in the shape of a shade that is opened downward as shown in FIG. 4, and the beam projector 32 is driven in the head body 31 by a control board 40. ) Is installed. It is preferable that the head body 31 has a plurality of heat dissipation holes 31a so as to discharge heat generated from the beam projector 32 to the outside.

The beam projector 32 is for performing skin care by irradiating light on the skin, and irradiating light of a desired wavelength to the entire face of the user through planar light control using a digital micromirror display (DMD), and By controlling the resolution and wavelength of light, it is possible to perform skin care using various wavelength bands. A pico projector may be used as a light source of the beam projector 32, and the pico projector may use a digital light processing (DLP), liquid crystal on silicon (LCOS), or a laser beam scanning (LBS) projection method.

DLP is a projection engine system adopted in a projector, and is a method of using a semiconductor element formed of a fine reflector assembly digital micromirror device (DMD). Since DLP projects using the reflection principle of a mirror, it has high light utilization efficiency, and can realize higher luminance than a transmissive liquid crystal system that projects a light source from the back side. In addition, since all controls are processed digitally, they outperform liquid crystals in resolution, and because of the single plate structure, it is advantageous for miniaturization.

DLP is a light source, a condensing lens, a color filter, a shaping lens, at least one digital micromirror device (DMD), a memory, a processor, and a projection lens. (projection lens) and the like may be provided. The DMD, memory and processor may be formed as a single module on a DLP board. Here, the DLP may correspond to a logo of a projection product of Texas Instruments.

LCOS is a projection type display device in which a silicon wafer is used instead of the glass at the bottom of the existing liquid crystal display (LCD) device and an electronic circuit is formed thereon. An electronic circuit that forms an image image by painting the surface of a silicon chip with crystal. Is a technology in which a reflective surface is placed inside a silicon chip painted with aluminum and is reflected on the silicon chip through a polarizing prism. A silicon liquid crystal display (LCoS) panel is a technology that reflects polarized light, while the principle is similar to that of LCD, but the LCD panel transmits light through each pixel. The light source (red, green, blue) from the lamp is reflected from the surface of the LCoS chip through a polarizing prism, and the reflected light source is formed as a single image in the lens through a secondary polarizing prism.

LBS displays an image by reflecting a light source through driving control for one micromirror, realizing a large screen through the driving angle of the micromirror, and improving image quality through the driving accuracy of the micromirror. The LBS may be equipped with a MEMS scanner, a dichroic filter, a laser diode and a collimator lens.

In addition, the head unit 30 includes a 3D camera 33 controlled by the control board 40. The 3D camera 33 measures the distance between the user's face and the beam projector 32 of the head 30, scans the user's face in three dimensions, and uses infrared rays to position each face. It performs the function of measuring the temperature. Information obtained by the 3D camera 33 is provided to the control board 40.

Meanwhile, a TOF (time of flight) sensor or a TOF camera may be used instead of the above-described beam projector 32, 3D camera 33, or both. The TOF camera may include a light source such as an LED emitting a very short infrared pulse and a photo detector such as a photo diode (PD) that detects reflected light reflected from an object. That is, the TOF camera generates a 3D image by measuring the flight time of light and detecting the distance to a point on the face surface. In this type of 3D camera, infrared light is continuously irradiated in nanoseconds (ns), and the distance is calculated by measuring a time when the light hits a subject and reaches the infrared camera. In this case, if a space corresponding to the user's face is divided into tens of thousands of regions, infrared light is irradiated to the region of the space, and a distance is calculated based on the reflected infrared light, a profile for the user's face can be generated.

In addition, a structured light (SL) type 3D camera may be provided instead of the above-described beam projector 32, the 3D camera 33, or both. This 3D camera is a 3D face recognition camera system, including a camera (see 33) and a projector (see 32), and the projector can use a dot projector and can be made to shoot an infrared pattern of tens of thousands of dots on the face.

The above-described 3D camera irradiates a pattern consisting of tens of thousands of dots in the camera image and the projector image on the face, and then reads the changes in the pattern distortion reflected according to the position and size of the eyes, nose, and mouth of the face, and curvature. Recognize. That is, the 3D camera is configured to search for the coincidence point of the structured light code and obtain the 3D coordinates of the point, and to calculate the 3D coordinates of the coincidence point, the camera and the projector can correct the images. have.

Correction can be implemented by image processing technology for images projecting a pattern in a plane unit, a pattern in a multi-direction, or a pattern in a multi-direction in a plane. Using these correction methods, a three-dimensional shape is restored. In this case, it is strong in geometric characteristics of the face surface and strong in color or contrast characteristics of the face surface, so that high-precision and high-accuracy images can be obtained, and efficiency is high.

On the other hand, when the TOF camera described above is used, the algorithm design is relatively simple because only the flight time of continuously irradiated light is measured. In addition, compared to the structured light-based 3D camera, the TOF camera accurately recognizes the distance to the human face, thereby improving the accuracy and precision of the 3D image of the user's face.

A sub-PCB (refer to 32a of FIG. 3) is installed between the beam projector 32 and the 3D camera 33 so as to be in charge of electrical connection thereof. The sub-PCB 32a has a thin square plate shape, but is not limited thereto.

The control board 40 includes a micro processor unit (MPU) 41, a storage unit 42, and a communication unit 43, as shown in FIG. 5. The MPU 41 is connected to control the first electric motor 51 of the left and right rotation means, and the second electric motor 61 of the height adjustment means, so that the position of the head unit 30 can be adjusted.

In addition, the MPU (41) is connected to the beam projector (32) to control the wavelength band, irradiation intensity and irradiation time suitable for skin care, and compares the information provided from the 3D camera (33) with preset reference data. After analysis, the position of the head unit 30 and the driving of the beam projector 32 can be controlled by setting a wavelength band of light or a beauty time suitable for a portion requiring skin care.

When a driving signal is input to the beam projector 32, driving information may be displayed outside the device. For example, the lower support 10 is provided with an indicator 71 and a speaker 77, is connected to the MPU 41 of the control board 40, the indicator 71 and the speaker 77 is a facial skin care device When used, the operation status is recognized by the user as a flashing and melody.

In addition, the MPU 41 stores information on skin beauty for each user in the storage unit 42 to enable continuous skin management, and information with an external device 72, for example, a computer or a smartphone, through the communication unit 43 To be able to give and receive.

A blocking plate (refer to 42 in FIG. 3) may be installed between the control board 40 and the headrest 11 to block pressure from outside the headrest from being transmitted to the control board 40. The blocking plate 42 may be made of a relatively hard material and may be installed in a size capable of covering the upper portion of the control board 40.

As shown in FIGS. 1 and 5, the control board 40 is connected to the switch 73 by wire, so that the user manipulates the switch 73 to turn the power on or off or pause, restart, and select the skin care mode during skin care. You can make it possible to directly control simple movements such as. The switch operation of each function by the switch 73 may be operated by having a plurality of switch buttons for performing each function, and as shown in the figure, when the switch is operated by pressing the switch 73 with only one switch button Each function can be performed by a separate operation by pressing and short or long. The switch 73 may be provided on the lower support 10 in duplicate, or a remote control 74 wirelessly connected to the control board 40 may be used as a switch operation means. The manipulated operation mode may be externally displayed in the form of color, blinking, etc. by the indicator 71.

MEMS 325 may include a MEMS mirror. The detailed configuration and operation principle of such a pico-projector may be referred to Laid-Open Patent Publication No. 10-2015-0024971.

The principle of operation of the facial skin beauty device configured as described above will be described as follows.

8 is a perspective view of a standby or storage state before use of a facial skin beauty device according to the present invention, FIG. 9 is a side view showing a use state of the facial skin beauty device according to the present invention, and FIGS. 10 to 14 are It is a rear view showing the state of use of the facial skin beauty device according to the following.

First, as shown in FIG. 8, when the facial skin beauty device is not used, the left and right rotation support structure and the left and right rotation means of the support column 20 provided between the lower support 10 and the support column 20 are used. The head part 30 is positioned on the floor by rotating the support column 20 to the left or right (left side based on the user in the drawing), and the upper column 22 using the height adjustment means provided in the support column 20 The length of the support column 20 can be kept in a storage position where the length of the support column 20 is shortened as much as possible by completely inserting the lower column 21, thereby protecting the head part 30 when storing the facial skin beauty device, and at the same time, the occupied space. Can be easily stored by minimizing.

In such a storage position, when the user operates the switch 73 or the remote control 74 to turn on the power for skin care, the first electric motor 51 of the left and right rotation means by the control board 40 The support column 20 is driven by the rotating plate 52 fixed to the motor shaft of the first electric motor 51 and the second rotating support 14 fixed to the lower column 21 of the support column 20. ) Is rotated in the vertical direction around the horizontal axis of the first rotation support 13, the head part 30 is moved to a vertically erected position just above the headrest 11 as shown in FIGS. 1 and 2 I can make it.

Subsequently, the second electric motor 61 of the height adjusting means provided in the support column 20 is driven so that the upper column 22 is moved with respect to the lower column 21 by the rack size gear 62 and the pinion gear 63. Since it is raised, it is possible to move the head unit 30 to a pre-set position to be used.

In this way, the initial operation after turning on the switch 73 may be programmed in advance on the control board 40 and performed automatically. For example, when the switch 73 is turned on, the indicator 71 provided on the head unit 30 is automatically flashed and the head unit 30 is moved at the storage position of FIG. When the head part 30 is rotated to the ready-to-use position shown in Fig. 1, and then, after about 1 to 2 seconds, the upper column 22 is moved upward by about 100mm to complete the movement of the head 30 to the standby-for-use position, the indicator 71 blinks. After finishing and maintaining the lighting state, it is possible to recognize to the user that the head unit 30 has been moved to the standby position for use. At this time, a melody or a buzzer sound may be made to sound through the speaker 77 to help the user's perception along with the blinking of the indicator 71 when moving.

Subsequently, as shown in FIG. 9, the user can use the facial skin beauty device while lying down while cutting his head on the headrest 11 and looking at the ceiling. At this time, the user is advised to wear protective glasses for eye protection, and the 3D camera 33 provided on the head part 30 scans the face of the user lying down on the headrest 11 and whether or not the protective glasses are worn. When detecting whether the pupil is detected and providing it to the control board 40, the control board 40 flashes the indicator 71 and generates a warning melody from the speaker 77 when it is determined that the user does not wear protective glasses. It may sound so that the user can recognize it, and at the same time, it is possible to prevent the operation from being performed despite the subsequent manipulation of the switch 73.

Subsequently, when the skin beauty mode is selected through the operation of the switch 73 or the remote control 74 in order to start the skin beauty, the beauty mode set in advance on the control board 40 can be automatically executed step by step. By driving the first electric motor 51 of the height adjustment means and the second electric motor 61 of the height adjustment means, the head part 30 is moved step by step to accurately position it in front of the target location for skin care, and at the same time, the bending change is For many faces, it is possible to perform skin care by irradiating light for a predetermined period of time while automatically maintaining the distance to the beam projector 32 accurately.

10 to 14 are use state diagrams showing an example of a beauty mode. As shown in FIG. 10, the head 30 is positioned vertically to perform skin care on the front part of the face, and then in FIG. As shown in Fig. 12, the head 30 is moved to the right 45 degrees to the right to perform skin care on the right edge of the face, and then the head 30 is 22.5 degrees to the right as in FIG. Move it to the position to perform skin care on the right middle part of the face, and then move the head 30 to the left 22.5 degree position as shown in FIG. 13 to perform skin care on the left middle part of the face, and then As shown in FIG. 14, by moving the head part 30 to the left 45 degree position to perform skin care on the left edge of the face, it is possible to automatically perform a uniform skin care on the entire face in stages.

As described above, while the head unit 30 is moved step by step, the indicator 71 blinks and a melody sounds in the speaker 77 so that the user can recognize that the head unit is moving to the next step.

On the other hand, during the use of the facial skin care device, when an emergency situation occurs and the operation of the product needs to be stopped, if the user presses the switch 73 once briefly, all operations are temporarily stopped, and the indicator 71 flashes. At the same time, the melody of the speaker 77 may sound a melody different from the melody during normal operation, so that the user may know that the date has been designated.

After the emergency situation is released, if the user manipulates the switch 73 once again briefly, the skin beauty mode that was being executed can be continued.
