Description

Technical Field

[0001] This invention relates to a skin beauty treatment device, and more specifically, to a skin beauty treatment device that can determine the contact state between the user's skin and the inhalation port based on the light-related skin color or light brightness measured in the target area of ​​inhalation when in contact with the user's skin. Background Technology

[0002] Generally speaking, an epilator is a device used to remove body hair, such as hair or hair follicles, that grows on human skin.

[0003] Traditional hair removal devices include razors that use razor blades to cut body hair and forced hair removal devices that remove hair roots by forcibly plucking body hair. However, although these hair removal methods are simple, they have the disadvantage of short duration.

[0004] Therefore, in recent years, laser hair removal has received attention as a solution to fundamentally inhibit hair growth.

[0005] Laser hair removal works by damaging the cells that produce hair, thus preventing hair from growing in the hair follicle. The hair follicle is the skin organ that produces hair; if the melanin cells in the hair follicle disappear, hair cannot grow again.

[0006] That is, by using pulsed light energy, based on the principle of selective photothermal decomposition, the light energy is absorbed by the melanin chromophores in the skin and converted into heat energy, which is then transferred to the hair follicle, thereby removing unwanted hair.

[0007] Patent Document 1: KR10-1784536B1

[0008] Patent document 1 discloses a device equipped with a vacuum module that uses the suction of a vacuum pump to force suction into the skin under negative pressure, thereby performing cosmetic treatment on the skin.

[0009] In Patent Document 1, in order to force the skin in contact with the end of the inhalation port to be sucked in by the vacuum suction force, i.e., negative pressure, of the vacuum module mounted on the beauty device, it is necessary to efficiently force the skin to be sucked in by the negative pressure generated when the opening end of the inhalation port is in uniform contact with the skin.

[0010] However, it is difficult to visually confirm whether the opening of the suction port is in uniform contact with the user's irregularly shaped skin. Furthermore, when the opening of the suction port is not in uniform contact with the user's skin and a gap is created, the skin suction caused by the vacuum module cannot be smoothly performed, thus making skin cosmetic treatment impossible or inefficient.

[0011] Furthermore, before the vacuum module operates, in order to maintain a tight seal between the user's skin and the inhalation port in the initial stage, the user needs to press the end of the inhalation port against the skin to force a tight seal, which causes inconvenience in use.

[0012] Furthermore, although a touch sensor is provided at the opening end of the inhalation port to sense whether or not there is contact when it comes into contact with the skin, thereby confirming the contact state between the skin and the inhalation port, the touch sensor alone cannot fundamentally sense the overall contact state between the opening end of the inhalation port and the skin. Summary of the Invention

[0013] The present invention aims to solve the above problems. The purpose of the present invention is to provide a skin beauty treatment device that judges the contact state based on the brightness of the skin color between the user's skin and the suction port that applies negative pressure, and controls the timing of the suction module's action.

[0014] Another object of the present invention is to provide a skin beauty treatment device that controls the output intensity of the inhalation module based on the skin color measured in the user's skin area.

[0015] The technical issues to be addressed by this invention are not limited to those described above. Other technical issues not mentioned can be clearly understood by those skilled in the art based on the following description.

[0016] According to one embodiment of the present invention, a skin beauty treatment device is provided, comprising: a body; an inhalation head having an inhalation port that contacts the skin at an end protruding outward from the body; a light irradiation module that irradiates light generated when powered onto the user's skin side in contact with the inhalation port; an inhalation module disposed inside the body and applying negative pressure to the inhalation port side when powered on, so as to raise the treatment area of ​​the skin in contact with the inhalation port; at least one optical sensor that senses and measures the light introduced internally through a light path formed at the end of the inhalation port in contact with the skin; and a control unit electrically connected to the light irradiation module and the inhalation module respectively; wherein the control unit determines the contact state between the inhalation port and the skin based on the measurement value sensed by the optical sensor, and selectively controls the timing of the operation of the inhalation module.

[0017] At this time, the optical sensor can be a color sensor, which senses the skin color of the skin area related to the light introduced through the optical path and converts the color information into an electrical signal.

[0018] At this time, the optical sensor can be an illuminance sensor, which senses the brightness of the light introduced through the optical path and converts the sensed light amount into an electrical signal.

[0019] At this time, the skin beauty treatment device includes at least one auxiliary optical sensor disposed on the inner wall of the inhalation port corresponding to the inhalation space formed inside the inhalation port. The auxiliary optical sensor can be any of the following sensors: a color sensor, which senses the skin color of the skin area related to the light introduced into the inhalation space and converts the color information into an electrical signal; and an illuminance sensor, which senses the brightness of the light introduced into the inhalation space and converts the sensed light amount into an electrical signal.

[0020] At this time, the control unit can control the output intensity of the light irradiation module based on the skin color sensed and measured in the color sensor.

[0021] At this time, the inhalation port may include at least one touch sensor, which generates a contact signal when its end contacts the skin, and transmits the generated contact signal to the control unit.

[0022] Based on the above configuration, the skin beauty treatment device of the present invention can accurately and easily confirm the contact state between the skin and the inhalation port by using real-time measurements of the light provided through the light path provided by the inhalation port that is in contact with the skin and the brightness value of the skin color or the brightness value of the light. Therefore, while precisely controlling the timing of the action of the inhalation module that applies negative pressure to the inhalation space, it can efficiently achieve the bulging of the skin area caused by the negative pressure applied by the inhalation module without avoiding unnecessary power loss.

[0023] Furthermore, by accurately determining the skin color based on measurements from optical sensors or auxiliary optical sensors that detect the skin color of the skin area, the output intensity of the laser used for hair removal is adjusted or stopped according to the determined skin color or the brightness of the skin color. Therefore, skin damage or burns can be avoided during hair removal, and hair removal can be safely performed on the skin treatment area, thereby improving user satisfaction and hair removal efficiency.

[0024] The effects of the present invention are not limited to those described above, but should be understood to include all effects that can be derived from the inventive structure described in the detailed description or claims of the present invention. Attached Figure Description

[0035] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings to enable those skilled in the art to readily implement the present invention. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. For clarity of illustration, parts in the drawings that are not related to the description are omitted, and throughout the specification, the same reference numerals are used for the same or similar constituent elements.

[0036] The words and terms used in this specification and claims should not be limited to their ordinary or dictionary meaning, but should be interpreted in accordance with the principle that the inventors are able to define terms and concepts in order to best illustrate their invention, so as to conform to the meaning and concept of the technical idea of ​​the invention.

[0037] Therefore, the embodiments described in this specification and the configurations shown in the accompanying drawings are only preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, at the time of application of the present invention, there may be various equivalents and modifications that can replace the configuration.

[0038] In this specification, terms such as "comprising" or "having" are intended to indicate the presence of the features, values, steps, actions, constituent elements, components or combinations thereof described in the specification, and should not be construed as excluding the possibility of the presence or addition of one or more other features, values, steps, actions, constituent elements, components or combinations thereof.

[0039] The location of a component "in front of," "behind," "above," or "below" another component, unless otherwise specified, includes not only situations where it is directly in contact with the other component and is positioned "in front of," "behind," "above," or "below," but also situations where other components are disposed between them. Furthermore, the "connection" of one component to another, unless otherwise specified, includes not only situations where they are directly connected but also situations where they are indirectly connected.

[0040] Hereinafter, a preferred embodiment of the skin beauty treatment device of the present invention will be described with reference to the accompanying drawings.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the skin beauty treatment device 1 of the preferred embodiment of the present invention may include a main body 10, an inhalation head 20, a light irradiation module 30, an inhalation module 40, a control unit, and an optical sensor 50.

[0042] Hereinafter, when describing with reference to the accompanying drawings, the direction in which the suction port 22 of the suction head 20 of the skin beauty treatment device 1 points is defined as forward, and the opposite direction is defined as rearward. The space of a certain size formed inside the suction port when the suction port 22 comes into contact with the skin is defined as the suction space S.

[0043] The skin beauty treatment device 1 applies a predetermined negative pressure to the suction port 22 of the suction head 20, which is in direct contact with the user's skin, thereby forcibly raising the skin to a certain height in the suction space S inside the suction port 22.

[0044] Furthermore, by bringing the raised skin close to the light irradiation module 30, the desired skin beauty treatment effects, such as improved light irradiation efficiency for hair removal and massage, can be achieved.

[0045] The application of the aforementioned negative pressure can be achieved through at least one suction module 40.

[0046] At this time, the skin beauty treatment device 1 of the present invention may include at least one optical sensor 50 disposed adjacent to the inhalation space.

[0047] The optical sensor 50 is a sensor component that senses internally introduced light through a light path 55 formed at the end of the inhalation port that contacts the skin, measures the brightness of skin color as skin tone or the brightness of light as illuminance, and performs optical processing on it.

[0048] The optical sensor 50 can be a color sensor, which senses the skin color of the skin area related to the light introduced through the light path 55 and converts the color information into an electrical signal, or it can be an illuminance sensor, which senses the brightness of the light introduced through the light path 55 and converts the sensed light amount into an electrical signal.

[0049] Furthermore, the control unit can determine the contact state between the end of the inhalation port 22 and the corresponding skin based on the brightness value of the skin color or the brightness value of the light sensed and measured in the optical sensor 50, and selectively control the timing of the operation of the inhalation module 40.

[0050] With the end of the suction port 22 in complete contact with the skin, the suction module 40 is activated to generate negative pressure in the suction space. This negative pressure is then applied to the skin area where cosmetic skin treatment is to be performed, causing the skin to bulge to a certain height.

[0051] Therefore, according to an embodiment of the skin beauty treatment device 1, before applying negative pressure to the skin for inhalation, it is possible to determine whether the skin and the inhalation port are in complete contact, thereby maximizing the skin beauty treatment effect.

[0052] The following is a detailed description of the various components of the skin beauty treatment device according to an embodiment of the present invention.

[0053] The skin beauty treatment device 1 of this invention includes a body 10.

[0054] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the main body 10 serves as a housing for accommodating other components and can be held by the user to operate and control the skin beauty treatment device 1.

[0055] The body 10 may have an internal space of a certain size for housing the inhalation module 40, and may be generally linear rod-shaped, or formed into a handle that can be held by the user.

[0056] The outer surface of the main body 10 may be provided with a display for showing the control status of the skin beauty treatment device 1, or a button component or touch screen for inputting signals to control the skin beauty treatment device 1.

[0057] On the other hand, the shape of the body 10 is not particularly limited and can be appropriately deformed according to the characteristics of other constituent elements contained inside or the usage environment.

[0058] The body 10 includes an inhalation head 20 having an inhalation port 22 with an end that contacts the skin. The internal space of the body 10 includes at least one inhalation module 40 that generates a negative pressure as suction when energized, and at least one light irradiation module 30 that generates a laser when energized may be included at the end of the body 10 adjacent to the inhalation module 40.

[0059] At this time, the suction head 20 can be detachably assembled to the end of the body.

[0060] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the suction head 20 can extend from and be integrally disposed with the body 10, or can be detachably assembled, and can include a suction port 22 that applies negative pressure to the skin area formed in direct contact with the skin.

[0061] At this time, the suction head 20 may have a funnel shape with a diameter that gradually decreases forward.

[0062] The suction head 20 includes a suction port 22 that opens forward, and at least one through hole 24 can be formed inside the suction port 22, which is connected to a vacuum suction pipe 42 extending from the suction module 40, thereby transmitting negative pressure as suction force to the suction space S.

[0063] In the inner region of the suction head 20 corresponding to the suction port 22, a transparent window 26 corresponding to the light source 32 of the light irradiation module 30 may be included for allowing processing light such as laser beams to pass through without damage and irradiate the skin side.

[0064] Therefore, an inhalation space can be formed between the inhalation port that contacts the skin and the transparent wall corresponding to the light source, so as to apply negative pressure to the skin in contact with the inhalation port and cause it to bulge to a certain height.

[0065] like Figure 4 As shown, the light irradiation module 30 may include at least one light source 32 for directly and concentratedly irradiating the skin raised by the suction of the suction module 40 with the processing light, i.e., laser, generated when the power is applied.

[0066] The light source 32 provided in the light irradiation module 30 may include an intense pulsed light (IPL) light source, a laser light source, or a flash lamp. When powered on, it irradiates the raised skin with a laser wavelength in the range of 560nm to 1100nm. The laser with high output energy causes the hair follicles and the area around the hair follicles to die, thereby performing the hair removal function.

[0067] The light source 32 includes a plurality of light-emitting diodes that generate light with high output energy in the wavelength range of 560nm to 1100nm when energized, and a substrate for mounting the plurality of light-emitting diodes can be disposed on the inner surface of the sealed end of the body 10.

[0068] like Figure 2 , Figure 3 and Figure 4 As shown, the inhalation module 40 can be configured inside the body 10 and can include at least one inhalation source that generates suction when energized to apply negative pressure to the skin through the inhalation space S.

[0069] The suction module 40 is configured to generate negative pressure in the suction space S formed inside the suction port 22 of the suction head 20. For example, it may be configured as a pump motor that forcibly draws in external air to generate negative pressure when energized.

[0070] The vacuum suction pipe 42 extending from the suction module 40 is connected to the connecting hole 24 that penetrates one or both sides of the inside of the suction port 22, and the exhaust pipe (not shown) extending from the suction module 40 can be connected to the exhaust hole that penetrates the outer surface of the body.

[0071] The negative pressure adjustment of the inhalation module 40 can be configured to be controlled by the control unit.

[0072] At this time, the inhalation module 40 can also be configured to adjust the intensity of the negative pressure by operating a button located on the outside of the main body, and the inhalation module 40 can be configured to have a variable output corresponding to the suction force.

[0073] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the optical sensor 50 is at least one sensor component disposed inside the inhalation head 20, which senses and measures the light introduced internally through the light path 55 disposed at the end of the inhalation port 22 that contacts the skin.

[0074] The optical sensor 50 can be a color sensor, which senses the skin color of the skin area corresponding to the light path 55 and converts the color brightness and skin tone as color information into an electrical signal as a measurement value; or it can be an illuminance sensor, which measures the amount of light obtained in the area corresponding to the light path 55 and converts it into an electrical signal as a measurement value according to the brightness of the light.

[0075] The light path 55 can be configured such that its light input end is disposed as the front end at an exposure hole formed through the end of the inhalation port 22 that contacts the skin, and the optical sensor 50 is located at the light output end as the rear end. It can be configured as a light guide made of a light-transmitting resin material, or it can be configured to extend from the exposure hole formed through the end of the inhalation port 22 that contacts the skin to the cavity of the optical sensor.

[0076] At this time, multiple optical sensors 50 can be arranged in pairs facing each other at the ends of the inlet 22, or multiple sensors can be arranged at equal intervals along the circumference with the center of the inlet 22 as a reference.

[0077] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the end of the inhalation port 22 may include at least one touch sensor 70, which generates a contact signal when in contact with the skin and transmits the generated contact signal to the control unit.

[0078] The touch sensor 70 makes initial contact with the skin and generates a contact signal as the end of the suction port 22 approaches the user's skin, and the contact signal can be transmitted to the control unit.

[0079] Based on the contact signal from the touch sensor 70, the control unit can control the light irradiation module 30 and the suction module 40, and switch the optical sensor 50, which is composed of a color sensor or an illuminance sensor, and the auxiliary optical sensor 60 from the rest mode where the power is completely cut off to the standby mode where a backup power is applied and they are in a working standby state.

[0080] The control unit is electrically connected to the light irradiation module 30 and the inhalation module 40 respectively to transmit control signals, and is electrically connected to the color sensor or illuminance sensor constituting the optical sensor 50 respectively to receive the brightness value of skin color or the brightness value of light. It can be set in the internal space of the body 10 or the internal space of the inhalation head 20.

[0081] The control unit can be implemented by a processor, a central processing unit (CPU), a controller, an arithmetic logic unit, an operational logic circuit, a digital signal processing device, a microcomputer, an FPGA, a system-on-a-chip (SoC), a programmable logic unit, a microprocessor, etc.

[0082] In this specification, electrical connection includes not only the case of conductive connection through electrical lines, but also the case of connection through known wireless communication methods.

[0083] Therefore, according to this embodiment, the control unit can obtain information as a predetermined measurement value from the optical sensor 50 or the auxiliary optical sensor 60 composed of the color sensor or the illuminance sensor, and configure the control unit to control the operation of the light irradiation module 30 and the operation of the inhalation module 40 based on the obtained information.

[0084] On the other hand, when the optical sensor 50 is a color sensor, the color sensor senses the light obtained through the light path 55 as color, measures the skin color as skin tone and the brightness value of the sensed skin color in real time, and transmits the information as the measurement value to the control unit.

[0085] This color sensor is used to detect the three primary colors of light: R (red), G (green), and B (blue). It receives light through a photodiode and detects the RGB values ​​to detect skin color as a skin tone and obtain the brightness value of the skin color.

[0086] For example, if the amount of light introduced through the light path 55 is large and bright, the resistance value related to the color brightness measured in the color sensor decreases; if the amount of light introduced through the light path 55 is small and relatively dark, the resistance value related to the color brightness measured in the color sensor increases, thereby the color brightness value can be obtained based on the variable resistance value.

[0087] In addition, the light source that provides the brightness of the light to be detected and measured for the color sensor can be natural light such as sunlight if the user uses the skin beauty treatment device outdoors, or artificial light such as indoor lighting if the user uses the skin beauty treatment device indoors.

[0088] like Figure 7a As shown, during the process of the end of the inhalation port 22 contacting the generally curved skin, a gap G is formed between the end of the inhalation port 22 and the skin. The input end of the optical path 55 can be completely exposed outside the end of the inhalation port 22, or partially exposed outside while in partial contact with the skin.

[0089] In this case, natural or artificial light can be introduced into the color sensor, which is an optical sensor, and sensed through the input end of the fully or partially exposed light path 55.

[0090] The brightness value of the skin color sensed and measured in the color sensor can be set to the maximum brightness exposure state "10" or a measurement value between "1" and "9" that is lower than the maximum value, based on the amount of light obtained through the light path. Based on this, the control unit can determine that the entire edge of the end of the inhalation port 22 is not in complete contact with the skin in a non-contact state or in an incomplete contact state.

[0091] On the contrary, such as Figure 7b As shown, when the end of the suction port 22 contacts the skin without forming a gap G, the input end of the light path 55 can be completely covered and sealed by the skin.

[0092] In this case, natural or artificial light cannot be introduced into the light path 55 covered by the skin, and therefore cannot be sensed by the color sensor, which is an optical sensor.

[0093] The brightness value of the skin color measured in the color sensor can be set to "0". Based on this, the control unit can determine that the light path 55 is in a completely dark state with no light entering, and at the same time determine that the entire edge of the end of the suction port 22 is in complete contact with the skin.

[0094] Therefore, when the brightness value of the skin color measured by the color sensor, which is the optical sensor, is a brightness value other than "0", the control unit can determine that the entire edge of the end of the inhalation port 22 is not completely in contact with the skin or is in a non-contact state, and can control the light irradiation module 30 and the inhalation module 40 to remain in standby mode.

[0095] Conversely, when the brightness value of the skin color measured by the color sensor is "0", the control unit can determine that the end of the inhalation port 22 is in close contact with the skin, and can control the activation of the inhalation module 40 to apply negative pressure to the skin to make it bulge.

[0096] On the other hand, the information of the skin color measured by the color sensor can be numerically distinguished and set based on the Fitzpatrick skin classification table, which is used to determine the skin brightness according to the skin hue and brightness.

[0097] That is, such as Figure 8As shown, the Fitzpatrick skin classification table divides skin color into six types based on skin color and skin reaction to sunlight. Very bright skin color is classified as Type 1, bright skin color as Type 2, skin color ranging from bright to medium as Type 3, medium skin color as Type 4, dark skin color as Type 5, and very dark skin color as Type 6.

[0098] Therefore, by comparing and determining the user's skin color, which is sensed and measured by the optical sensor 50 (which is the color sensor), with the six skin colors classified in the Fitzpatrick skin classification table in the control unit, the user's skin color can be selected and determined as any one of type 1 to type 6.

[0099] At this time, when the control unit determines that the user's skin color measured by the color sensor is a darker type 5 or a very dark type 6, the intensity of the laser for hair removal output by the light irradiation module 30 and irradiated towards the skin can be reduced, or the light irradiation can be interrupted.

[0100] This is because hair removal is based on the absorption of light energy by the melanin pigments in the skin. Therefore, the darker the skin color, such as type 5 or type 6, the higher the absorption rate of light energy, which may lead to skin damage caused by laser.

[0101] Furthermore, when the optical sensor 50 is an illuminance sensor, the illuminance sensor is a sensor component that senses the amount of light obtained through the light path 55, measures the brightness of the light as internal illuminance in real time, and transmits the information as the measured value to the control unit.

[0102] This illuminance sensor, which measures the amount of light sensed, i.e., the brightness of light, has a resistance value that changes according to the amount of light obtained through the light path, thereby obtaining the brightness value of light.

[0103] For example, if a large amount of light is introduced into the light path 55, the resistance value related to the brightness of the light measured in the illuminance sensor decreases; if a small amount of light is introduced into the light path 55, the resistance value related to the brightness of the light measured in the illuminance sensor increases. Thus, the brightness value of the light can be obtained based on this variable resistance value.

[0104] In addition, the light source that provides the illuminance sensor with the light intensity to be sensed and measured can be natural light such as sunlight if the user uses the skin beauty treatment device outdoors, or artificial light such as indoor lighting if the user uses the skin beauty treatment device indoors.

[0105] like Figure 7a As shown, during the process of the end of the inhalation port 22 contacting the generally curved skin, a gap G is formed between the end of the inhalation port 22 and the skin. The input end of the optical path 55 can be completely exposed outside the end of the inhalation port 22, or partially exposed outside while in partial contact with the skin.

[0106] In this case, natural or artificial light can be introduced into the illuminance sensor, which is an optical sensor, and sensed through the input end of the fully or partially exposed light path 55.

[0107] The brightness value of the light sensed and measured in the illuminance sensor can be set to the maximum brightness exposure state "10" or a measurement value between "1" and "9" that is lower than the maximum value, based on the amount of light obtained through the light path 55. Based on this, the control unit can determine a non-contact state in which the entire edge of the end of the inhalation port 22 is not in complete contact with the skin, or an incomplete contact state in which the skin is not completely adhered.

[0108] On the contrary, such as Figure 7b As shown, when the end of the suction port 22 contacts the skin without forming a gap G, the input end of the light path 55 can be completely covered and sealed by the skin.

[0109] In this situation, natural or artificial light cannot be introduced into the interior of the light path 55 covered by the skin, and therefore will not be sensed by the illuminance sensor, which acts as an optical sensor.

[0110] The brightness value of the light measured in the illuminance sensor can be set to "0". Based on this, the control unit can determine that the light path 55 is in a completely dark state with no light entering, and at the same time determine that the entire edge of the end of the inhalation port 22 is in complete contact with the skin.

[0111] Therefore, when the brightness value of the light measured by the illuminance sensor, which is the optical sensor, is a brightness value other than "0", the control unit can determine that the entire edge of the end of the inhalation port 22 is not completely in contact with the skin or is in a non-contact state, and can control the light irradiation module 30 and the inhalation module 40 to remain in standby mode.

[0112] Conversely, when the illuminance value of the light measured by the illuminance sensor is "0", the control unit can determine that the end of the inhalation port 22 is in close contact with the skin, and can control the activation of the inhalation module 40 to apply negative pressure to the skin to make it bulge.

[0113] On the other hand, such as Figure 5 and Figure 6As shown, it may include at least one auxiliary optical sensor 60, which is disposed on the inner wall of the inhalation port 22 corresponding to the inhalation space S formed inside the inhalation port 22.

[0114] The auxiliary optical sensor 60 can be selectively configured as any of the following sensors: a color sensor that determines the skin color and measures the brightness of the skin color based on the light introduced into the inhalation space S; or an illuminance sensor that measures the brightness of the light introduced into the inhalation space S.

[0115] The optical sensor 50 and the auxiliary optical sensor 60 can be configured as different types of sensors, or they can be configured as the same type of sensors.

[0116] Furthermore, the auxiliary optical sensor 60 can be configured as a stand-alone sensor component that senses and measures the light introduced into the inhalation space S without the optical sensor 50 exposing the input end of the light path to the end of the inhalation port.

[0117] Figure 9a , Figure 9b and Figure 9c To illustrate the action state diagrams of the skin beauty treatment device according to an embodiment of the present invention, including its application, inhalation, and exhaust processes, Figure 10 This diagram illustrates the sequence of operations of the skin beauty treatment device according to an embodiment of the present invention.

[0118] First, in order to use the skin beauty treatment device according to an embodiment of the present invention to raise the skin to be hair removed by negative pressure, and then use a laser to perform hair removal beauty treatment on the raised skin, the suction head 20 is first set opposite to the skin to be hair removed.

[0119] In this state, when the end of the inhalation port 22 is brought close to the skin, the touch sensor 70 provided at the end of the inhalation head makes contact first and generates a contact signal, which is then transmitted to the control unit.

[0120] At this time, based on the contact signal of the touch sensor, the light irradiation module 30 and the suction module 40 are given a backup power supply and converted to a preparation mode. The optical sensor 50 and the auxiliary optical sensor 60, which are composed of the color sensor or the illuminance sensor, are also given a backup power supply, thereby converting to a preparation mode for measuring skin color and the brightness of skin color or the brightness of light.

[0121] This preparation mode can be activated by pressing the start button located on the main body.

[0122] Furthermore, when the end of the inhalation port 22 is in contact with the skin, the optical sensor 50, which is composed of the color sensor or the illuminance sensor, and the auxiliary optical sensor 60 can measure the brightness value of the skin color related to the light introduced through the light path 55 and sensed, or measure the brightness value of the light introduced into the inhalation space S.

[0123] That is, such as Figure 7a As shown, when light is introduced through the input end of the light path exposed at the end of the inlet 22, or when light is introduced into the inlet space, the brightness value of the skin color or the brightness value of the light, measured by the optical sensor 50, which is a color sensor or an illuminance sensor, and the auxiliary optical sensor 60, is any measured value other than "0" which represents the dark state. This measured value corresponds to "10" which represents the non-contact state and between "1" and "9" which represent the incomplete contact state, and is transmitted to the control unit.

[0124] Conversely, when the input end of the light path exposed at the end of the suction port 22 is completely covered by skin or the suction space is completely closed, such as Figure 7b and Figure 9a As shown, no gap G is formed between the end of the inlet 22 and the skin, and since external light cannot be introduced through the input end of the light path 55 or the inlet space, the brightness value of the skin color or the brightness value of the light, which is measured by the optical sensor 50, which is a color sensor or an illuminance sensor, or an auxiliary optical sensor, is measured as a "0" value representing a dark state and is transmitted to the control unit.

[0125] In this case, the control unit can determine, based on the information transmitted from the optical sensor 50 and the auxiliary optical sensor 60 as measured values, whether the end of the inhalation port 22 is in a state of incomplete contact with the skin or a state of complete and uniform contact between the end of the inhalation port 22 and the skin.

[0126] When the control unit determines that the contact is incomplete, the inhalation module 40 remains in standby mode; conversely, when the control unit determines that the contact is complete, power is supplied to the inhalation module 40 to generate the suction force, thereby causing the inhalation module 40 to apply negative pressure to the inhalation space S, which can cause the skin in contact with the end of the inhalation port to bulge.

[0127] Therefore, based on the contact signal from the touch sensor and the brightness value of the skin color or light in the suction space measured by the optical sensor 50 and the auxiliary optical sensor 60, the close contact state of the end of the suction port with the skin of the treatment area to be treated for hair removal can be accurately confirmed, and the operation of the suction module 40 can be performed without loss of suction.

[0128] like Figure 9b As shown, when the end of the inhalation port 22 is in complete close contact with the skin, when the inhalation module 40 is activated and applies negative pressure to the inhalation space S, the skin corresponding to the inhalation space S can bulge out to a certain height towards the light irradiation module 30.

[0129] Furthermore, by irradiating the skin side that has bulged to a certain height under the negative pressure applied in the suction space S with the laser generated when the light irradiation module 30 is activated, hair removal can be performed by the laser.

[0130] At this time, the skin color can be determined as any one of six types based on the brightness value of the skin color measured by the optical sensor 50 or the auxiliary optical sensor 60, which is a color sensor, and the intensity of the laser irradiated by the light irradiation module 30 onto the skin side can be controlled.

[0131] That is, when the skin color measured by the color sensor is determined in the control unit to be type 1 to 4 out of type 1 to 6, lasers with output control at a preset light intensity can be irradiated onto the raised skin side according to very bright skin color, bright skin color, skin color ranging from bright to medium skin color and medium skin color, or lasers with output control at a preset uniform light intensity can be irradiated onto the raised skin side, thereby enabling laser-based hair removal without concerns about skin damage or burns.

[0132] Furthermore, when the upper part of the raised skin becomes wide and flat under the negative pressure of the suction module 40, it is preferable to maintain the negative pressure applied by the suction module 40 during a certain period of hair removal by the laser of the light irradiation module 30.

[0133] Conversely, when the brightness value of the skin color measured by the color sensor is determined in the control unit to be type 5 or 6 out of type 1 to 6, since irradiating skin with dark or very dark skin with laser may cause skin damage and burns, it can be controlled to not supply power to the light irradiation module side.

[0134] At this time, the color sensor used to measure the skin color of the skin area to be hair removed can measure the skin color of the exposed skin area by external light such as natural light or artificial light before the end of the suction port 22 comes into contact with the skin, or measure the skin color of the exposed skin area by light from an illumination source (not shown) in a dark state where the end of the suction port is in complete close contact with the skin.

[0135] Ultimately, as Figure 9cAs shown, when hair removal is performed on the treatment area by irradiating the treatment area of ​​the skin raised under the negative pressure of the suction module 40 with the laser of the light irradiation module 30, the negative pressure of the suction space S can be eliminated by selectively opening the exhaust port provided on the body 10 and connected to the exhaust pipe of the suction module 40, thereby restoring the skin raised under the negative pressure to its original state and ending the entire hair removal process.

[0136] Although embodiments of the present invention have been described, the concept of the present invention is not limited to the embodiments shown in this specification. Those skilled in the art, based on their understanding of the concept of the present invention, can easily propose other embodiments by adding, changing, deleting or adding constituent elements without departing from the scope of the present invention, and these embodiments should also fall within the scope of the present invention.
