Description

[Technical Field]

[0001] The present invention relates to a cosmetic treatment device, and more particularly to a cosmetic treatment device having a non-contact sensor that detects the height of raised skin without contacting the skin of a user. [Background technology]

[0002] Recently, home beauty treatment devices that allow users to perform beauty treatments such as massage and hair removal at home have become increasingly popular. Home beauty treatment devices allow users to easily perform beauty treatments at home at a time of their choice, lowering the barrier to beauty treatments and increasing accessibility.

[0003] As the popularity of home beauty treatment devices increases, the performance of the devices has improved dramatically compared to previous models, and the effectiveness of treatments is also increasing. This means that if the user does not use the device safely or properly, the possibility of side effects occurring and the severity of the side effects may increase.

[0004] Specifically, for example, home beauty treatment devices perform hair removal, massage, etc. using light, high frequency, etc., but when high frequency is applied to the skin for beauty treatments or treatments, deep heat is generated along with the appropriate treatment effect only when the high frequency electrode and the skin are in close contact with each other.

[0005] However, if high frequency waves are applied when the contact area between the cosmetic treatment device and the skin is small due to factors such as the contact angle between the device and the skin, pressure fluctuations, or skin bending, the current density increases, creating a risk of burns.

[0006] As a result, as the performance and effectiveness of home beauty treatment devices have improved, there is a need to ensure that skin stimulation is only possible when the contact surface of the beauty treatment device body comes into contact with the skin, in order to avoid dangers caused by incorrect or unintended use of the product. Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a beauty treatment device that prevents excessive high-frequency electrode power from being transmitted to the user's skin by measuring the contact state of the stimulation application unit with the user's skin in a non-contact manner.

[0008] Another object of the present invention is to provide a cosmetic treatment device that reduces discomfort and skin stress caused by heat during cosmetic skin treatment.

[0009] The objects of the present invention are not limited to those mentioned above, and other objects not mentioned will be clearly understood by those skilled in the art to which the present invention pertains from the following description. [Means for solving the problem]

[0028] 1 to 3, a cosmetic treatment device 100 according to an embodiment of the present invention is a cosmetic treatment device that allows a user to perform a cosmetic treatment on his or her own skin. Meanwhile, a user can also perform a cosmetic treatment on a patient using the cosmetic treatment device 100.

[0029] For example, the cosmetic treatment device 100 according to an embodiment of the present invention can provide a suction function that uses high-frequency stimulation to suck and stimulate the user's skin, provide a massage to the user's skin using high-frequency electrodes, or perform a hair removal function.

[0030] Components for cosmetic treatment may be disposed in the main body 110. For example, a stimulator 130 for high-frequency stimulation and a light source for irradiating light may be disposed in the main body 110. Also, a component for providing a suction function for stimulating the user's skin by suction may be disposed in the main body 110.

[0031] As shown in FIG. 1, a handle 112 may be provided on the upper side of the body 110 so that a user can grip and move the cosmetic treatment device 100.

[0032] The main body 110 may also include an operation button 103 for inputting operation information such as turning on / off the beauty treatment device 100 and selecting various modes. This is merely an example, and a touch screen or the like may be provided on the main body 110 instead of the operation button 103.

[0033] Meanwhile, the cosmetic treatment device 100 according to the embodiment of the present invention may include an output unit 104 for outputting a signal, a message, etc. for providing information to a user. In this case, the output unit 104 may be a speaker for outputting sound or voice.

[0034] A display for displaying visual information may be provided around the body 110. The display may also display the direction of movement of the body 110.

[0035] Meanwhile, the beauty treatment device 100 according to the embodiment of the present invention is provided with a treatment unit 120 in the main body 110, in which a treatment space 120a for treating the user's skin is formed.

[0036] The treatment unit 120 is disposed on the opposite side of the handle unit 112 across the periphery 111 of the main body 110. In this case, the treatment unit 120 is formed so that the treatment space 120a has a rectangular parallelepiped shape. However, the treatment space 120a is not limited to a rectangular parallelepiped shape, and may have various shapes such as a polygonal shape, an elliptical cylinder, or a cylindrical shape.

[0037] Meanwhile, the treatment space 120a of the treatment unit 120 is provided with suction ports 172a and 172b for drawing air into the treatment space 120a to perform the suction function of the cosmetic treatment device 100. The detailed configuration for performing the suction function of the cosmetic treatment device 100 will be described with reference to the following drawings.

[0038] Furthermore, the cosmetic treatment device 100 according to the embodiment of the present invention includes a stimulus applying unit 130 that applies a stimulus to the skin of the user.

[0039] The stimulation unit 130 is disposed in the treatment space 120a. The stimulation unit 130 receives power and generates high-frequency stimulation. As shown in FIG. 3, the stimulation unit 130 includes a first electrode 131 and a second electrode 132.

[0040] The first electrode 131 has a plate shape with a certain thickness.

[0041] The second electrode 132 has a plate shape with a certain thickness. The first electrode 131 may have the same size and shape as the first electrode 131. The second electrode 132 is disposed apart from the first electrode 131. At this time, the second electrode 132 is disposed next to the first electrode 131. Accordingly, the user's skin is placed in a protruding state between the first electrode 131 and the second electrode 132, and the first electrode 131 and the second electrode 132 come into contact with the protruding skin to apply high-frequency stimulation to the protruding skin.

[0042] Furthermore, the beauty treatment device 100 according to the embodiment of the present invention is provided with a temperature sensor 250 for measuring the temperature of the treatment space 120a. As shown in Fig. 3, the temperature sensor 250 is disposed in the central region of the treatment space 120a when viewed from below.

[0043] At this time, the temperature sensor 250 is disposed in the central region of the treatment space 120a, and is therefore disposed at a position corresponding to the raised skin of the user, so that the temperature sensor 250 has the advantage of accurately measuring the temperature adjacent to the raised skin.

[0044] The temperature sensor 250 measures the temperature of the treatment space 120a to prevent excessive heat from being transferred to the user's skin during the cosmetic treatment. The temperature sensor 250 will be described in detail below with reference to the accompanying drawings.

[0045] FIG. 4 is a cross-sectional view focusing on the treatment unit of a beauty treatment device according to an embodiment of the present invention, FIG. 5 is a perspective view showing the treatment unit, stimulus application unit, and sensor unit of a beauty treatment device according to an embodiment of the present invention separated from each other, FIG. 6 is a perspective view showing the treatment unit of a beauty treatment device according to an embodiment of the present invention separated from the main body, and FIG. 7 is a view showing the beauty treatment device according to an embodiment of the present invention performing a beauty treatment on a user's skin.

[0046] 4 to 7, the cosmetic treatment device 100 according to the embodiment of the present invention includes a sensor unit 200 that senses whether the user's skin is in contact with the stimulators 131 and 132.

[0047] The sensor unit 200 is disposed in the treatment unit (120, see FIG. 2). The treatment unit 120 is provided with a partition 140 that separates the treatment space 120a from the inside of the main body (100, see FIG. 2).

[0048] The partition 140 has a first side 141 formed inside the main body 110 and a second side 142 formed in the treatment space 120a. A support part 145 having a central groove 140a communicating with the treatment space 120a is provided in the central region of the partition 140. The support part 145 protrudes from the first side 141 and has a cylindrical shape.

[0049] Meanwhile, a temperature sensor 250 for measuring the temperature of the treatment space 120a is provided above the central groove 140a. As the temperature sensor 250 is positioned at the center of the treatment space 120a, it is aligned perpendicular to the raised skin of the user, allowing for accurate measurement of the temperature around the raised skin.

[0050] The sensor unit 200 is disposed on the first side surface 141 of the partition unit 140. The sensor unit 200 senses a change in capacitance to detect whether the user's skin is in contact with the stimulators 131 and 132. To this end, the sensor unit 200 includes a first sensor unit 210 having a ring shape and a second sensor unit 230 disposed at a distance from the first sensor unit 210.

[0051] The first sensor unit 210 is disposed on the first side surface 141 and is formed to surround the outer surface of the support unit 145. Accordingly, the first sensor unit 210 maintains a non-contact state with the user's skin, and therefore does not need to transmit an electrical signal to the user's skin to check the swelling state of the user's skin, thereby preventing unnecessary electrical stimulation from being applied to the user's skin.

[0052] In addition, the first sensor unit 210 is formed to surround the outer surface of the support unit 145, so as not to interfere with the temperature measurement by the temperature sensor 250, and is positioned adjacent to the protruding skin of the user, so that the height of the protruding skin can be measured accurately.

[0053] In addition, the first sensor unit 210 is formed to surround the outer surface of the support unit 145 and is disposed on the first side surface 141, and is disposed at a position corresponding to the protruding skin of the user, thereby enabling precise measurement of the height of the protruding skin.

[0054] The second sensor unit 230 is disposed above the support part 145 to be spaced apart from the first sensor unit 210. The second sensor unit 230 receives power and detects capacitance using an electric force with the first sensor unit 210. Accordingly, the second sensor unit 230 measures a change in capacitance due to swelling of the user's skin based on the capacitance with the first sensor unit 210.

[0055] Through this, the sensor unit 200 measures a change in capacitance caused by the raised skin, and senses the state in which the raised skin is in contact with the stimulation applying units 131 and 132 .

[0056] Accordingly, according to an embodiment of the present invention, the area of ​​contact between the user's skin and the stimulation application units 131 and 132 is reduced excessively, thereby preventing the high-frequency stimulation from the stimulation application units 131 and 132 from being applied excessively to the user's skin.

[0057] The support part 145 includes a first support part 221 that supports the temperature sensor 250. The support part 145 includes a second support part 222 that surrounds the first support part 221 and the temperature sensor 250. The second support part 222 prevents air from flowing in or out between the through hole 140a and the inside of the body 110.

[0058] FIG. 8 is a block diagram of a cosmetic treatment device according to an embodiment of the present invention.

[0059] Referring to FIG. 8, the cosmetic treatment device according to the embodiment of the present invention may include a suction source 320, a pump discharge passage 340, a chamber 350, a chamber discharge passage 360, a first valve 370, a second valve 380, and a control unit 390.

[0060] The suction source 320 is disposed in the main body 110 and generates negative pressure. The suction source 320 may be disposed in the internal space of the main body 110. The negative pressure generated by the suction source 320 may provide a suction function for sucking the user's skin into the treatment space (120a, FIG. 7) during cosmetic treatment. For example, the suction source 320 may be an air pump.

[0061] The suction passage 330 is connected to the suction source 320 so that the negative pressure draws external air into the suction source 320. The suction passage 330 has a plurality of suction ports (172a, 172b, see FIG. 2) facing the treatment space 120a.

[0062] The plurality of intake ports 172a, 172b include a first intake port 172a formed on a second side 142, which is the opposite side of the first side 141 of the partition portion (140, see Figure 2), and a second intake port 172b formed on the opposite side of the first intake port 172a across the support portion 145.

[0063] Accordingly, when the suction source 320 is operated during a cosmetic treatment, air present between the main body 110 and the user's skin is sucked into the suction passage 330, and the user's skin is sucked into the treatment space 120a.

[0064] The pump discharge passage 340 is connected to the suction source 320 so that the air drawn into the suction source 320 is discharged to the outside of the suction source 320. The pump discharge passage 340 may be disposed inside the main body 110. When the suction source 320 is operated, a negative pressure is generated in the suction passage 330, and air flows into the suction passage 330 through the plurality of suction ports 172a and 172b. The air that flows into the suction passage 330 flows into the suction source 320 and is discharged to the outside of the suction source 320 through the pump discharge passage 340.

[0065] The chamber 350 is connected to the pump discharge passage 340 and disposed in the body 110 to store the air discharged through the pump discharge passage 340. The chamber 350 may be disposed in the interior space of the body 110. For example, the chamber 350 may be disposed adjacent to the suction source 320. When the suction source 320 is operated, air is drawn into the suction source 320 through the suction passage 330, discharged to the outside of the suction source 320 through the pump discharge passage 340, and then flows into the chamber 350 and is stored in the chamber 350.

[0066] The chamber exhaust passage 360 ​​is connected to the chamber 350 so that the air stored in the chamber 350 can be discharged to the outside. The air stored in the chamber 350 can be discharged to the outside through the chamber exhaust passage 360. At this time, an outlet 360a of the chamber exhaust passage 360 ​​can be disposed to discharge the air toward the user's skin.

[0067] In one embodiment of the present invention, the pump discharge passage 360 ​​may partially overlap with the suction passage 330. For example, the pump discharge passage 360 ​​may be connected to one side of the suction passage 330, and a portion of the pump discharge passage 360 ​​may partially overlap with a portion of the suction passage 330. In this case, the outlet 360a of the pump discharge passage 360 ​​may be the same as the plurality of suction ports 172a and 172b of the suction passage 330. In other words, the outlet 360a of the pump discharge passage 360 ​​may become the plurality of suction ports 172a and 172b of the suction passage 330, and the plurality of suction ports 172a and 172b may become the outlet 360a. This structure may maximize the utilization efficiency of the internal space of the body 110.

[0068] The first valve 370 is disposed to open and close the pump discharge passage 340. For example, the first valve 370 may be a solenoid valve. The opening and closing of the first valve 370 may be controlled by the control unit 390.

[0069] The first valve 370 is opened when the suction source 320 is operated. Air drawn into the suction passage 330 by the negative pressure generated by the suction source 320 flows into the chamber 350 via the suction source 320 and the pump discharge passage 340. On the other hand, when the first valve 370 is closed, the suction source 320 and the chamber 350 are isolated from each other.

[0070] The second valve 380 is disposed to open and close the chamber exhaust passage 360. For example, the second valve 380 may be a solenoid valve. The opening and closing of the second valve 380 may be controlled by the controller 390.

[0071] In one embodiment of the present invention, the second valve 380 can be opened while the first valve 370 is closed. When the second valve 380 is opened, the air stored inside the chamber 350 flows into the pump discharge passage 360 ​​due to the internal pressure and is discharged to the outside through the outlet 360a of the pump discharge passage 360. The air discharged through the outlet 360a can provide a blowing function to the user during cosmetic treatment. The air discharged through the outlet 360a of the pump discharge passage 360 ​​can reach the user's skin to cool and soothe the user's skin.

[0072] Meanwhile, the second valve 380 may be closed when the suction source 320 is operated. As described above, the first valve 370 may be opened when the suction source 320 is operated, and the air flowing into the suction passage 330 due to the operation of the suction source 320 flows into the chamber 350 via the suction source 320 and the pump discharge passage 340. At this time, since the second valve 380 is closed, the air flowing into the chamber 350 is stored inside the chamber 150 without being discharged to the outside through the chamber discharge passage 360.

[0073] The control unit 390 controls the suction source 320, the first valve 370, and the second valve 380. The control unit 390 may include one or more processors, memory elements, etc. capable of storing and processing data.

[0074] In addition, the control unit 390 is electrically connected to the sensor unit 200 and the stimulus applying unit 130, and controls the operation of the stimulus applying unit 130 by receiving an electrical signal from the sensor unit 200.

[0075] In addition, the control unit 390 is electrically connected to the temperature sensor (250, see FIG. 2). The temperature sensor 250 measures the temperature of the area around the user's skin or the user's skin during the cosmetic treatment, thereby providing information that can determine whether the user feels uncomfortable due to heat or whether there is a risk of burns.

[0076] In cooperation with the temperature sensor 250, the control unit 390 may close the first valve 370 and open the second valve 380 to discharge the air stored in the chamber 350 to the chamber discharge passage 360 ​​when the temperature measured by the temperature sensor 250 during a cosmetic treatment is higher than a set reference temperature. In this case, the reference temperature may refer to a temperature at which the user feels discomfort or may be burned. When the temperature measured by the temperature sensor 250 is higher than the set reference temperature, the air in the chamber 350 may be discharged to the user's skin through such control, and the discharged air may cool and soothe the user's skin.

[0077] Although the embodiments of the present invention have been described, the concept of the present invention is not limited to the embodiments presented in this specification, and a person skilled in the art who understands the concept of the present invention may easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same concept, which may also fall within the scope of the concept of the present invention.
