Description

{PORTABLE SMART DEVICE FOR CARING FOR SKIN AND EYE}

The present invention relates to a portable smart device for skin beauty and eye care, and more particularly, to a portable smart device for skin beauty and eye care, which is easy to carry and operate, and which uses vibration, visible light, and near-infrared rays to stimulate the skin and eyes (including the eyelids) to improve skin health, and to relieve eye fatigue and promote eye health.

As interest in skin beauty has increased recently, various types of skin care devices for skin improvement have been developed and released. Skin care devices improve skin health by stimulating the skin using skin care methods such as negative ions, near-infrared rays, high-frequency waves, or ultrasound (e.g., HIFU: High Intensity Focused Ultrasonic).

However, the following improvements are required in skin care devices according to conventional technology.

First, there is difficulty in popularization. For example, skin care devices using high frequency or ultrasound may be difficult to popularize because they are manufactured as relatively expensive products (for therapeutic purposes).

Second, it is difficult to operate. Since the intensity or function cannot be controlled while in contact with the skin, and must be controlled after being separated from the skin, the operation can be complicated and cumbersome.

Third, product expandability and usability are limited. Since most of them are manufactured specifically for the purpose of improving skin beauty, the expandability and usability of functions other than skin beauty may be limited.

Referring to FIGS. 1 to 4, a portable smart device (10) according to an embodiment of the present invention provides a device capable of simultaneously implementing skin care and eye care using a single device, and the overall shape can be formed in a capsule shape in consideration of design and portability.

As shown in FIGS. 2 and 3, a portable smart device (10) according to an embodiment of the present invention includes a first care module (11) that provides micro-vibrations and visible light in the 380 nm to 780 nm band, and a second care module (12) that provides micro-vibrations and near-infrared light (heat) in the 0.78 μm to 2.5 μm band.

The first and second care modules (11, 12) are installed in a symmetrical structure on both sides, i.e., the left and right sides, as shown in FIGS. 2 and 3, and can be driven independently, or driven independently in response to a control signal from the control module (13), or driven in conjunction with each other.

FIG. 5 is a block diagram schematically illustrating the configuration of a portable smart device according to an embodiment of the present invention.

Referring to FIGS. 2 to 5, the first care module (11) is a module installed at the center of the portable smart device (10), for example, on the left side, and provides vibration and visible light.

The first care module (11) includes, as shown in FIGS. 2 to 5, a visible light LED (112) mounted on a first circuit board (printed circuit board, 111), a first vibration cover (113) covering the front side of the first circuit board (111), a first vibration motor (114) installed on the rear side of the first circuit board (111) to vibrate the first vibration cover (112), and a first push switch (115) installed on the rear side of the first circuit board (111).

The first circuit board (111) is installed in a vertically erected structure facing one side, for example, the left side, and is protected by the first vibration cover (113). In addition, a plurality of visible light LEDs (112) that emit visible light toward the front side (left side) are mounted on the front side of the first circuit board (111).

The first circuit board (111) is electrically connected to the control module (13), and the first care module (11) is controlled by the operation of the first push switch (115) or is controlled by the control module (13). To this end, the first circuit board (111) may be equipped with an active and/or passive element for driving a visible light LED (112) in response to the operation of the first push switch (115).

As shown in Fig. 5, the visible light LED (112) includes color LEDs that provide a visible light band. For example, at least two or more, and preferably three or more color LEDs may be included among a blue LED (112a), a green LED (112b), a yellow LED (112c), and a red LED (112d).

The characteristics of each LED are as shown in [Table 1] below.

The blue LED (112a), green LED (112b), yellow LED (112c) and red LED (112d) of the visible light LED (112) can be selectively operated in response to the operation of the first push switch (115). An example of the operation is illustrated in the operation flowchart of Fig. 5.

Figure 6 is a flow chart schematically illustrating an example of the operation of a visible light LED according to the present invention.

As shown in FIGS. 3 to 6, when the portable smart device (10) is turned on (S1), the first push switch (115) is operated (by pressing) to drive the visible light LED (112) (S2).

When the first push switch (115) is pressed, the portable smart device (10) can be powered and operated. At this time, the number of times the first push switch (115) is pressed can be one.

Depending on the number of times the first push switch (115) is pressed consecutively, one of the blue LED (112a), green LED (112b), yellow LED (112c), or red LED (112d) can be driven (S3 to S10).

For example, in the present invention, as shown in FIG. 6, the blue LED (112a) (once), the green LED (112b) (twice), the yellow LED (112c) (three times), and the red LED (112d) (four times) can be sequentially driven according to the number of times the first push switch (115) is pressed continuously within a set time.

As shown in FIGS. 2 to 4, the first vibration cover (113) may be formed in a dome shape so that a first circuit board (111) may be installed inside. The first vibration cover (113) may be formed of a synthetic resin material or rubber material that is transparent or translucent and elastic so that light emitted from a visible light LED (112) mounted on the front side of the first circuit board (111) may be transmitted to the outside.

The first vibration motor (114) is installed on the rear side of the first circuit board (111) and can be driven in conjunction with the operation of the first push switch (115) or in response to a control signal of the control module (13).

The first push switch (115) is installed on the rear side of the first circuit board (111), and when the user presses the first vibration cover (113) toward the second care module (12), that is, from the left to the right, the first vibration cover (113) is pushed to the right and is pressed to the right, thereby performing a switch operation.

That is, when the first vibration cover (113) is pressed toward the skin while in contact with the skin, the first vibration cover (113) is pushed to the right by the pressing force, and in this process, the first push switch (115) is pressed by the first vibration cover (113) to operate (turn on), and the visible light LED (112) and the first vibration motor (114) are driven. Therefore, there is an advantage of ease of use compared to the prior art.

The first care module (11) according to the present invention may further include a first sealing ring (116) that seals between the end of the case in which the upper cover (16) and the lower cover (17) are assembled vertically, that is, the left end, and the first vibration cover (113).

The first sealing ring (116) may be formed of an O-ring structure. The first sealing ring (116) is installed at the assembly site of the first vibration cover (113), the upper cover (116), and the lower cover (17) in a state where the right end of the first vibration cover (113) is assembled to the left end of the upper cover (16) and the lower cover (17) which are assembled vertically, thereby sealing them and preventing foreign substances or moisture from entering the interior.

In addition, the first sealing ring (116) is made of a synthetic resin material or rubber material having elasticity. When the portable smart device (10) is pushed toward the skin while the first vibration cover (113) is in contact with the skin, a counteraction occurs in the first vibration cover (113) with a force corresponding to the force applied toward the skin, causing it to move in the opposite direction to the force applied toward the skin (to a distance capable of operating the first push switch (115)), and after the external force is removed, it returns to its original state. The synthetic resin material or rubber material having elasticity is made of the same.

As shown in FIGS. 2 to 4, the second care module (12) according to the present invention is installed on the right end of the case to form a symmetrical structure with the first care module (11), and includes a second circuit board (121), a near-infrared LED (122), a second vibration cover (123), a second vibration motor (124), a second push switch (125), and a second sealing ring (126).

The second circuit board (121), the second vibration cover (123), the second vibration motor (124), the second push switch (125), and the second sealing ring (126) may have the same configuration as the first circuit board (111), the first vibration cover (113), the first vibration motor (114), the first push switch (115), and the first sealing ring (116) of the first care module (11), and therefore, a detailed description thereof will be replaced with the above-mentioned content.

Near-infrared LED (122) provides near-infrared rays in the 0.78㎛ to 2.5㎛ band, and is irradiated deep into the skin up to 4mm to prevent skin pigmentation, promote regeneration, and provide warm heat.

As shown in FIGS. 2 to 4, a portable smart device (10) according to an embodiment of the present invention may further include a first protective cover (14) to cover and protect the first vibration cover (113), and a second protective cover (15) to cover and protect the second vibration cover (123). The first and second protective covers (14, 15) may be formed in a dome shape corresponding to the shapes of the first and second vibration covers (113, 123).

The first and second protective covers (14, 15) are assembled to both ends of the upper cover (16) and lower cover (17) which are assembled vertically. At this time, they can be detachably combined in a male-female manner. In addition, as shown in Fig. 1, at least a part of the first sealing ring (116) is installed overlapping between the first protective cover (14) and the upper cover (16) and the lower cover (17), and at least a part of the second sealing ring (126) is installed overlapping between the second protective cover (15) and the upper cover (16) and the lower cover (17).

The first and second protective covers (14, 15) may be formed with a structure having a curved outer surface for design purposes. For example, the first and second protective covers (14, 15) may be formed with a symmetrical structure and may be formed to have an approximate egg shape when assembled with each other. In addition, the first and second protective covers (14, 15) may be formed of a transparent, translucent, or opaque material.

In the present invention, when massaging the facial skin and eyelids using only vibration, the first and second protective covers (14, 15) may be made of a soft synthetic resin material or rubber material so that they can be used in a state where they are assembled to the upper cover (16) and the lower cover (17). That is, when the first and second protective covers (14, 15) are assembled to the upper cover (16) and the lower cover (17), the first and second protective covers (14, 15) can be brought into direct contact with the skin to stimulate the skin.

The upper cover (16) and the lower cover (17) are assembled together to form a case of a portable smart device (10). The upper cover (16) and the lower cover (17) can be assembled vertically in a male-female or forced-fit manner and then fastened to each other using fastening members such as pieces (screws) or bolts.

As shown in FIGS. 2 and 4, a switch support member (161) is formed on the upper cover (16). The switch support member (161) is formed in a structure that protrudes downward from the lower portion of the upper cover (16), and has an insertion hole (161a) formed at the lower portion that is open downward and into which push buttons (115a, 125a) of the first and second push switches (115, 125) are inserted, and a support piece (161b) is formed on the rear side of the insertion hole (161a) to support the push buttons (115a, 125a) inserted into the insertion hole (161a) toward the rear side.

When the portable smart device (10) is pressed toward the skin while the first vibration cover (113) is in contact with the skin, the first vibration cover (113) is pushed toward the center of the case by the pressing force. Then, the first push switch (115) is also pushed toward the center of the case by the first vibration cover (113) being pushed. At this time, in the process, the push button (115a) of the first push switch (115) is pressed and operates by being supported by the support piece (161b) toward the center of the case. The second push switch (125) also performs a switching operation through the same process.

As shown in FIG. 5, a portable smart device (10) according to an embodiment of the present invention may include a power supply unit (18), a built-in battery (19), and a power port (20). The built-in battery (19) is installed inside the upper cover (16) and the lower cover (17), and may be a rechargeable battery (e.g., a lithium battery) that is charged by an external power source supplied from the outside through the power port (20).

The control module (13) is driven by power supplied from a power port (20) or a built-in battery (19). The control module (13) includes a main board (printed circuit board, 131) electrically connected to the first and second circuit boards (111, 121), and a power port (20) is mounted on the main board (131), and also a driving chip for driving a portable smart device (10) is mounted.

As shown in FIG. 5, a portable smart device (10) according to an embodiment of the present invention may further include an operation indicator light (21) that indicates the operation and/or charging status of the portable smart device (10), and an LED color indicator light (22) that indicates an operating LED among visible light LEDs (112).

The LED color indicator light (22) operates in conjunction with the blue LED (112a), the green LED (112b), the yellow LED (112c), and the red LED (112d), respectively. For example, when the blue LED (112a) operates, the blue light lights up, when the green LED (112b) operates, the green light lights up, when the yellow LED (112c) operates, the yellow light lights up, and when the red LED (112d) operates, the red light lights up.

The portable smart device (10) according to an embodiment of the present invention may further include a memory (23). The memory (23) stores a preset driving algorithm in the form of a program corresponding to the characteristics of the body part where care is currently being provided. The control module (13) controls the driving conditions of the first and second care modules (11, 12) according to the program stored in the memory (23).

The memory (23) stores a program that controls the operation of the first and second care modules (11, 12) in response to the characteristics of facial skin, skin around the eyes, or eye couple skin, respectively.

Facial skin, skin around the eyes, or eye couple skin have different skin thickness and skin tissue. For example, facial skin is relatively thicker and has different skin tissue than eye couple skin. Therefore, when the first and second care modules (11, 12) are operated, the intensity (strength) of vibration and visible light, or the intensity (strength) of vibration and near-infrared light is set differently depending on the skin of the body part where care is currently being performed, and this is programmed and stored in the memory (23).

A skin elasticity measurement sensor (24) may be installed to determine the body part where care is currently being performed. The skin elasticity measurement sensor (24) may measure the elasticity of the skin of the body part where care is currently being performed, for example, to determine the body part where care is currently being performed. For example, the measurement may be performed by applying negative pressure to the skin for a preset period of time, measuring the skin deformation length by angle, and then calculating the skin elasticity index based on the average or standard deviation of the deformation length by angle. In addition, the measurement may be performed using any one of the known skin elasticity measurement methods.

The memory (23) stores the average skin elasticity value for each body part, and the control module (13) can compare the measured value from the skin elasticity measurement sensor (24) with the average skin elasticity value for each body part stored in the memory (23) to determine the area where care is currently being provided.

Accordingly, the portable smart device (10) according to an embodiment of the present invention can automatically determine the body part on which care is being provided through the skin elasticity measurement sensor (24), and based on this, the first and second care modules (11, 12) care for the skin and eyes under optimized conditions for each body part, thereby maximizing the skin beauty effect and promoting eye health.

For example, in the eyelids, which are relatively thinner and have weaker skin tissue compared to the facial skin, the intensity of vibration, visible light, or near-infrared light is weakened. This prevents strong stimulation of the pupil, thereby relieving eye fatigue and promoting health.

The skin elasticity measurement sensor (24) can be installed on the first or second vibration cover (113, 123) that is in direct contact with the skin.

As shown in FIG. 5, a portable smart device (10) according to an embodiment of the present invention may further include an input unit (25) and/or a communication unit (26) for an interface with a user.

The input unit (25) provides for changing or updating the setting values, etc. stored in the memory (23). For example, the average skin elasticity value for each body part stored in the memory (23) can be changed or updated. In addition, the intensity values of the initial vibration, visible light or near-infrared light provided from the first and second care modules (11, 12) can be set or adjusted.

As shown in Fig. 5, the communication unit (26) receives user skin information (dryness, oiliness, elasticity, etc.) from the user terminal (1) by wirelessly communicating with the user terminal (1) and stores it in the memory (23). In addition, it connects the user terminal (1) and the control module (13). An app (APP) for controlling a portable smart device (10) is installed in the user terminal (1), and the portable smart device (10) can be controlled remotely using the app installed in the user terminal (1).

The control module (13) can control the operation of the first and second care modules (11, 12) in response to a control signal of the user terminal (1), and can also register and update user skin information provided from the user terminal (1) in the memory (23). In addition, the operation of the first and second care modules (11, 12) can be controlled in response to the user skin information stored in the memory (23).
