Description

Apparatus capable of plasma irradiation and skin condition measurement

Technical Field

The present invention relates to an apparatus capable of plasma irradiation and skin condition measurement.

Background

Recently, home care apparatuses have been developed which can be easily managed at home without dermatology or a separate skin care shop. Home care facilities are superior in both time and cost compared to dermatology and skin care shops, and thus the demand for home care facilities is increasing.

Further, there is an increasing demand for a measuring apparatus that can measure a skin condition and a treating apparatus that can improve the skin, in which the measuring apparatus is in contact with or spaced apart from a skin surface to be measured to measure the skin condition.

At this time, the measuring device is held in a random direction while the user uses the measuring device, and the measurement of the skin is performed in a different direction every time the user uses the measuring device. However, there is a problem in that if measurements are performed in different directions, even if the same area is photographed, the accuracy of skin measurement is lowered when photographed images are analyzed and compared thereafter, and then calculation time is unnecessarily increased in order to make the direction of the photographed images constant and to perform the comparison.

For example, korean patent document No. 10-1929360 relates to a skin beauty apparatus that integrates skin diagnosis and treatment and that applies plasma by performing diagnosis and analysis on the skin of a user, but has a problem in that when the skin of a user is photographed, it is not aware of adjustment to photographing in a specific direction, and therefore, the accuracy of skin measurement is lowered.

For example, korean patent document No. 10-1147811 relates to a skin care apparatus and relates to diagnosing and analyzing a user's skin and applying ultrasonic waves through a main contact pad, but has a problem in that when the user's skin is photographed, it is not recognized to adjust to photographing in a specific direction, and thus, the accuracy of skin measurement is lowered.

Detailed Description

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

For convenience, in fig. 1, the measurement module 200 side is described as the front, and the plasma irradiation module 300 side is described as the rear.

The plasma apparatus according to the present invention includes a housing 100, a measurement module 200, a plasma irradiation module 300, a photo activation module 400, and a manipulation module 500.

The configuration of the plasma apparatus will be described with reference to fig. 1 to 4.

The case 100 covers an internal structure of the plasma apparatus, and includes a first case 110, a second case 120, and a cover 130.

The first housing 110 is a housing covering one surface of the plasma apparatus, the second housing 120 is a housing covering the other surface of the plasma apparatus, and the first housing 110 and the second housing 120 are coupled to each other.

In this case, the first case 110 and the second case 120 have a structure that can be separated right/left, but are not limited thereto, and the structure that can be coupled and separated from each other is not limited thereto.

The cover 130 is coupled to the rear of the first and

second housings

110 and 120, respectively.

The cover 130 is coupled with both the first and

second housings

110 and 120 to prevent the first and

second housings

110 and 120 from being separated, and to configure the inside of the housing 100 as a waterproof structure.

The measurement module 200 is a module for measuring the skin condition of the user, and can photograph the skin condition of the user.

In this case, the measurement module 200 may have an optical microscope structure, but is not limited thereto.

The measuring module 200 includes a reflecting unit 210, a light emitting unit 220, a viewing mirror wheel 230, a viewing mirror guide 240, a viewing mirror bracket 250, a photographing unit 260, and a lens guide 270.

The reflection unit 210 is located in front of the measurement module 200, and may be coupled to a sight glass wheel 230, which will be described later.

The reflection unit 210 may have a truncated cone shape, but is not limited thereto.

The reflection unit 210 includes a lens 211 and a reflection hole 212.

The lens 211 is formed inside the reflection unit 210.

In this case, the type and position of the lens 211 are not limited to the illustrated strip.

Light irradiated from a light emitting unit 220, which will be described later, may be reflected from the skin, and the reflected light may reach the photographing sensor 261 through a lens 211 located at the inner side of the reflection unit 210. As will be described later.

The reflection hole 212 is a hole formed at the foremost of the reflection unit 210, and is formed such that light irradiated from the light emitting portion 220 is reflected from the skin and enters the inside of the reflection unit 210.

The light emitting part 220 is located at the outer circumference of the reflecting unit 210 and in front of the scope guide 240.

The light emitting unit 220 includes a plurality of light emitting elements 221.

The light emitting element 221 emits light, and the light is irradiated onto the skin of the user.

At this time, since the light emitting units 220 are arranged along a circle around the outer circumference of the reflection unit 210, the skin may be irradiated with uniform light, and since the uniform light is irradiated, it is not necessary to constantly adjust the intensity of the light when performing calculation by subsequently acquiring skin images through AI, so that the calculation speed may be increased.

In this case, the light emitting unit 220 may be coupled to the viewing mirror guide 240, but is not limited thereto.

In this case, it has been described that the light emitting unit 220 includes the light emitting elements 221, but is not limited thereto, and the number of the light emitting elements 221 is not limited to the illustrated number and position.

The observation mirror wheel 230 is coupled to the reflection unit 210, and extends to the photographing unit 260.

The viewing mirror wheel 230 can move the reflecting unit 210 in a forward or backward direction, and thus the focus can be adjusted by adjusting the distance between the lens 211 and the user's skin.

In order to manipulate the observation mirror wheel 230, a hole is formed in the housing 100 at an upper side of the observation mirror wheel 230.

The scope guide 240 is located inside the scope wheel 230.

The scope guide 240 may be located inside the scope wheel 230 to constitute a lens barrel and a light shielding film of the lens 211 located inside the reflection unit 210.

That is, the sight glass guide 240 may provide a dark room between the photographing sensor 261 and the reflection unit 210.

The above-described light emitting unit 220 may be coupled to the front of the viewer guide 240, the reflection unit 210 is located in front of the viewer guide 240, and the photographing sensor 261, which will be described later, is located in the rear.

The sight glass holder 250 is formed such that the measurement module 200 is accommodated inside the case 100.

The scope bracket 250 is coupled to the rear of the scope guide 240.

The scope holder 250 is larger than the diameter of the photographing unit 260.

The observation mirror bracket 250 is formed at the center thereof with a hole aligned with the photographing sensor 261 and the reflection hole 210.

The photographing unit 260 may be positioned at the rear of the sight glass holder 250, and the photographing unit 260 closes the rear of the measuring module 200, so that the measuring module 200 may be spatially separated from the plasma irradiating module 300, which will be described later.

The photographing unit 260 includes a photographing sensor 261, and the photographing sensor 261 may be positioned to communicate with an inner side of the reflection part 210, so that the skin of the user may be photographed by sensing light reflected from the skin.

In this case, the photographing sensor 261 may be a CMOS sensor, but is not limited thereto.

The lens guide 270 is located outside the reflection unit 210.

The lens guide 270 covers the outer circumference of the light emitting part 220, so that loss of light irradiated from the light emitting part 220 can be prevented.

The lens guide 270 extends longer than the reflection unit 210 to provide a dark room between the photographing sensor 261 and the photographing surface S.

That is, when the lens guide 270 contacts the photographing surface S, the lens guide 270 may provide a dark room between the photographing sensor 261 and the photographing surface S.

Accordingly, the light reflected by the reflection unit 210 may be irradiated from the light emitting device 221 and reflected, so that the influence of the external light source may be eliminated. Thereafter, when the AI analyzes the photographed image, the image may be calculated using uniform light irradiated and reflected from the light emitting device 221 without being affected by an external light source. Therefore, since it is not necessary to consider the influence of the external light source, the calculation speed can be improved.

The lens guide 270 is detachable from the housing 100, and the user can separate the lens guide 270 from the housing 100 as desired.

Further, a portion of the lens guide 270 contacting the photographing surface S may be formed in various diameters and may be formed of various materials, so that the user may replace and use the lens guide 270 as needed.

For example, the diameter of the portion of the lens guide 270 in contact with the photographing surface S may be formed to be 20 pi or 100 pi so that the user can replace and use according to the area to be measured.

Further, for example, when measuring the skin condition of the scalp using a plasma apparatus, the lens guide 270 made of a silicon material may be used.

However, the length of the lens guide 270 is constant and the distance of the light irradiated from the light emitting unit 220 may be kept constant, but is not limited thereto, and the length of the lens guide 270 may be adjusted as necessary to adjust the distance of the light irradiated from the light emitting unit 220.

Further, the lens guide 270 surrounds the outside of the reflection unit 210 and extends to a position more forward than the reflection unit 210, and the lens guide 270 includes a plurality of

protrusions

271, 272 protruding at the same angular intervals as each other in the circumferential direction along the front end of the outer surface of the lens guide 270.

At this time, the first protrusions 271 are located at the uppermost and lowermost ends of the lens guide 270, and the second protrusions 272 may be positioned to be spaced apart at the same angle as each other with reference to the first protrusions 271, the first protrusions 271 may be adjusted to be vertically aligned with the z-axis, and the x-axis level may be adjusted by the second protrusions 272, but is not limited thereto.

In this case, the first projection 271 and the second projection 272 are not limited to the illustrated positions.

When the user uses the plasma apparatus, the apparatus is held in an arbitrary direction each time, and the skin is photographed in a different direction.

However, if photographing in different directions, there is a problem in that the accuracy of skin measurement is reduced even if the same region is photographed, and a calculation time (preprocessing time) is unnecessarily increased in order to make the image direction after photographing constant and to make comparison. Therefore, it is difficult to confirm whether images are captured in the same area, and images must be compared while rotating 360 degrees, which takes a lot of time to analyze and reduces efficiency.

In the present invention, by forming the first protrusion 271 and the second protrusion 272 on the lens guide 270 that can be seen by the user, the user adjusts the x-axis and the z-axis so that the direction in which the photographing sensor 261 photographs is kept constant. The connection line connecting the first protrusions 271 is perpendicular to the ground and photographing is performed at a position where the second protrusions 272 are parallel to the ground, so that the photographing direction can be made constant.

Therefore, when the ai analysis image is used later, the orientation criterion will be set so that a quick analysis can be performed. In particular, there is an effect that the current data can be easily compared with the past data. That is, when comparing the current skin data with the past data, the past data and the current data can be easily compared and analyzed using the AI if the criterion is established.

At this time, the lens guide 270 may be fixed to the housing 100 and thus may not idle or arbitrarily rotate with respect to the housing 100.

The plasma irradiation module 300 includes a plasma sphere 310, a plasma sphere guide 320, an electrode 330, and a transformer 340.

Plasma bulb 310 receives a high voltage from transformer 340, which will be described later.

The gas is stored inside the plasma sphere 310.

At this time, the gas is filled with argon gas or the like, power is applied from the battery 510 to the transformer 340 according to an operation of a plasma irradiation module switch 530 described later, and the plasma bulb 310 may apply plasma to the skin of the user by applying a high voltage boosted from the transformer 340 to the electrode 330.

In this case, the plasmon ball 310 may be in the shape of a glass ball, but is not limited thereto.

Plasma ball guide 320 is coupled to the outer circumference of plasma ball 310 and is located between plasma ball 310 and housing 100.

In this case, the plasma ball guide 320 may be made of a flexible material such as TPE or silicon to stably hold the plasma ball 310 and prevent foreign substances from penetrating to the inside of the case 100.

Electrode 330 is formed to extend from the outside to the inside of plasma sphere 310.

The electrode 330 receives a boosted voltage from a transformer 340, which will be described later.

The transformer 340 is located between the plasma irradiation module 300 and the measurement module 200.

The transformer 340 is used to boost the voltage.

When the plasma irradiation module switch 530 is operated, the battery 510 inputs a voltage to the transformer 340, and the transformer 340 boosts the input voltage.

In this case, the transformer 340 may boost the input voltage by at least 100 times to 1000 times, but is not limited thereto.

When a boosted voltage is applied to plasma sphere 330 through electrode 330, argon gas may be activated to generate plasma, so that plasma may be applied from plasma sphere 310 to the skin of the user.

At this time, the power applied from transformer 340 to plasma bulb 310 may be controlled within the supplied power range in consideration of the temperature rising from plasma bulb 310, so that ozone generation in the plasma apparatus may be minimized.

The photographing activation module 400 will be described with reference to fig. 5 to 8.

The plasma apparatus according to the present invention may further include a photographing activation module 400 to control a direction of photographing the skin, in addition to the first and

second protrusions

271 and 272 described above.

The photographing activation module 400 is located in the plasma apparatus such that the direction of photographing is constant when the skin is measured using the plasma apparatus.

The photographing activation module 400 includes three or more axes of multi-axis sensors, and controls the photographing sensor 261 to operate within a predetermined angle range between the photographing sensor 261 and the photographing surface S.

In this case, the angle refers to an angle formed by a normal line of the photographing activation module 400 at the center of the photographing surface S and a line passing through the center of the photographing sensor 261 and the center of the photographing surface S. Referring to fig. 7, an angle formed by a normal line at the center of the photographing surface S and a line passing through the center of the photographing sensor 261 and the center of the photographing surface S is described, and a bold line represents the normal line.

In this case, the photographing surface S refers to a skin surface to be measured by the user, and may be a surface irradiated by the light emitting element 221, but is not limited thereto.

Accordingly, since the photographing sensor 261 can photograph within a predetermined angle range, the skin of the user can be photographed only in a specific direction.

At this time, since the face has irregularities, a normal direction (i.e., an angle the normal forms with the ground) at the center of the imaging surface S may vary depending on the position of the imaging surface S. However, in the present invention, when the angle of the plasma device is inclined according to the unevenness of the face, the angle formed by the normal line at the center of the photographing surface S and the line passing through the center of the photographing sensor 261 and the center of the photographing surface S is compared, and the photographing sensor 261 can photograph the skin of the user in a specific direction by being within a predetermined angle range regardless of the unevenness of the face.

In this case, the predetermined angle range may be within 20 °, and the predetermined angle range may be 0 °, but is not limited thereto.

It is reasonable that the predetermined angle refers to an angle in three dimensions (x-y-z space), and it is preferable that the photographing sensor 261 is activated only in a case where angles formed on the photographing surface S by the photographing sensor 261 are all within a predetermined angle range in the x-y plane, the y-z plane, and the x-z plane. In this case, in fig. 8, it is shown that the photographing sensor 261 is activated only when the angles in the x-y plane, the y-z plane, and the x-z plane are within a predetermined angle range, respectively.

Further, the photographing activation module 400 performs control in consideration of the following conditions: the photographing surface S and the photographing sensor 261 are within a predetermined angle range; the distance between the photographing sensor 261 and the photographing surface S is within a predetermined distance. That is, the photographing activation module 400 may control the photographing sensor 261 to photograph the photographing surface S only when the plasma apparatus is separated from the photographing surface S within a predetermined distance.

In this case, the photographing activation module 400 may rotate the plasma apparatus such that the plasma apparatus is located within a predetermined angle range, and for this, the photographing activation module 400 may partially rotate the plasma apparatus including the elastic body, but is not limited thereto.

In this case, the location of the photographing activation module 400 may be located inside the measurement module 200, near the measurement module 200, particularly near the photographing sensor 261, but is not limited thereto.

The manipulation module 500 includes a battery 510, a measurement module switch 520, and a plasma irradiation module switch 530.

The battery 510 is a part that supplies power to the plasma apparatus, and may be replaced and used, and may supply charged power to the battery 510 according to the operations of the measurement module switch 520 and the plasma irradiation module switch 530.

The measurement module switch 520 is a switch that applies power to the measurement module 200.

The plasma irradiation module switch 530 is a switch that applies power to the plasma irradiation module 300.

LEDs capable of visualizing the state of the plasma apparatus may be located at the outer circumference of the plasma irradiation module switch 530. For example, if the LED is red, then it is charged; if the color is green, the state is a fully charged state; and if blue, indicates an in-use state.

In this case, the measurement module switch 520 and the plasma irradiation module switch 530 are not limited to the illustrated positions.

In the foregoing, the present specification has been described with reference to the embodiments shown in the drawings so that those skilled in the art can easily understand and reproduce the present invention, but these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible according to the embodiments of the present invention.
