[0027] The words and terms used in this specification and claims should not be interpreted limited to their ordinary or dictionary meanings, but should be interpreted as meanings and concepts that are consistent with the technical idea of ​​the present invention, based on the principle that the inventor can appropriately define the concepts of terms in order to best describe his or her invention.

[0028] As used herein, terms such as "comprise" or "have" are intended to describe the presence of features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0029] Fig. 1 is a block diagram of a cosmetic treatment device according to an embodiment of the present invention, Fig. 2 is a front upper perspective view of the cosmetic treatment device according to an embodiment of the present invention, and Fig. 3 is a rear lower perspective view of the cosmetic treatment device according to an embodiment of the present invention.

[0030] The cosmetic treatment device 100 according to an embodiment of the present invention allows a user to directly perform a cosmetic treatment on their own skin. That is, a user can directly perform a cosmetic treatment by bringing the cosmetic treatment device 100 according to an embodiment of the present invention into contact with their own skin. For example, the cosmetic treatment device 100 according to an embodiment of the present invention can perform high-frequency massage, laser hair removal, etc. Additionally, a suction function can be provided to stimulate the skin by suction.

[0031] 1 to 3, a cosmetic treatment device 100 according to an embodiment of the present invention may include a main body 110, a direction display unit 120, a displacement sensor unit 130, a control unit 140, and a warning output unit 150.

[0032] The main body 110 has a shape that can contact a predetermined area of ​​the user's skin. A configuration for cosmetic treatment may be disposed in the main body 110. For example, a configuration (not shown) for irradiating high frequency or laser may be disposed in the main body 110. The main body 110 may also be disposed with a configuration (not shown) for providing a suction function that sucks and stimulates the user's skin.

[0033] In one embodiment of the present invention, the main body 110 includes a first portion 111, the lower side of which is in contact with the user's skin and in which components for a cosmetic treatment are disposed, and a second portion 112 connected to the upper side of the first portion 111 so as to be gripped by the user. In this case, the first portion 111 may be cylindrical, and the second portion 112 may be arched. When the first portion 111 is cylindrical, it can improve the uniformity of contact with the user's skin. In addition, the user can easily move the main body 110 while gripping the second portion 112, and can appropriately press the first portion 111 against the user's skin.

[0034] A plurality of direction display units 120 are arranged on the main body 110 so as to respectively indicate different directions. In one embodiment of the present invention, the plurality of direction display units 120 may be arranged at least on the front, rear, left, and right sides of the main body 110. In other words, the plurality of direction display units 120 may include a first direction display unit 121 that displays the front direction of the main body 110, a second direction display unit 122 that displays the rear direction of the main body 110, a third direction display unit 123 that displays the left direction of the main body 110, and a fourth direction display unit 124 that displays the right direction of the main body 110.

[0035] Each of the plurality of direction display units 120 may include at least one direction display light source. In other words, the plurality of direction display units 120 can display a direction through light emitted by a light source.

[0036] In one embodiment of the present invention, the first direction display unit 121 may include two direction display light sources. For example, the first direction display unit 121 may include a 1-1 direction display light source 121a and a 1-2 direction display light source 121b. More specifically, the 1-1 direction display light source 121a may be disposed in front of the upper side of the first part 111 of the main body 110. Furthermore, the 1-2 direction display light source 121b may be disposed below the 1-1 direction display light source 121a.

[0037] The 1-1 direction display light source 121a can illuminate or blink to indicate the area in front of the main body 110. The 1-2 direction display light source 121b can emit light having directionality toward the direction to be displayed. For example, the 1-2 direction display light source 121b can emit linear light toward the front of the main body 110.

[0038] At least one of the plurality of direction display units 120 may include a direction display light source that irradiates light indicating a direction onto the user's skin. For example, in one embodiment of the present invention, the first and second direction display light sources 121b may irradiate light onto the user's skin located on the front side of the main body 110.

[0039] In this case, the first and second direction display light sources 121b may irradiate the user's skin with light having a predetermined shape (for example, an arrow shape), thereby allowing the user to visually and reliably recognize the direction in which the main body 110 can move or the direction in which the main body 110 will move.

[0040] In one embodiment of the present invention, the first direction display unit 121 includes both the 1-1 direction display light source 121a and the 1-2 direction display light source 121b, but this is merely an example. In a modified example of the embodiment of the present invention, the first direction display unit 121 may include only one of the 1-1 direction display light source 121a and the 1-2 direction display light source 121b.

[0041] In one embodiment of the present invention, the second direction display unit 122 to the fourth direction display unit 124 may each include two direction display light sources, similar to the first direction display unit 121. More specifically, the second direction display unit 122 may include a 2-1 direction display light source 122a that is arranged at the rear portion of the main body 110 and that displays the rear portion of the main body 110 by lighting up or blinking, and a 2-2 direction display light source 122b that is arranged at the rear portion of the main body 110 and that can emit a linear light directed toward the rear of the main body 110 or a light directed toward the skin of a user located behind the main body 110. The third direction display unit 123 may include a 3-1 direction display light source 123a disposed on the left side of the main body 110 and configured to illuminate or flash to indicate the left side of the main body 110, and a 3-2 direction display light source 123b disposed on the left side of the main body 110 and capable of emitting a linear light directed toward the left side of the main body 110 or light directed toward the skin of a user located on the left side of the main body 110. The fourth direction display unit 124 may include a 4-1 direction display light source 124a disposed on the right side of the main body 110 and configured to illuminate or flash to indicate the right side of the main body 110, and a 4-2 direction display light source 124b disposed on the right side of the main body 110 and capable of emitting a linear light directed toward the right side of the main body 110 or light directed toward the skin of a user located on the right side of the main body 110.

[0042] FIG. 4 is a diagram illustrating an example of a direction display by a direction display unit of a cosmetic treatment device according to an embodiment of the present invention.

[0043] 4, when the direction in which the main body 110 of the cosmetic treatment device 100 according to an embodiment of the present invention can move or is moving is the front of the main body 110, the 1-1 direction display light source 121a of the first direction display unit 121 disposed in front of the main body 110 may light up or blink. In addition, the 1-2 direction display light source 121b may irradiate light toward the skin of the user located in front of the main body 110. In this case, the light irradiated by the 1-2 direction display light source 121b may have an arrow shape.

[0044] The displacement sensor 130 is disposed on the main body 110 and senses the displacement of the main body 110 during a cosmetic treatment. The displacement sensor 130 may include at least one of an inertial sensor, a gyro sensor, and an acceleration sensor. The displacement sensor 130 senses the displacement of the main body 110 after the start of the cosmetic treatment and provides the sensed displacement to the control unit 140. Based on the information sensed by the displacement sensor 130, the control unit 140 can determine the path the main body 110 has traveled since the start of the cosmetic treatment, the relative positional relationship between the start position of the cosmetic treatment and the current position of the main body 110, etc.

[0045] The control unit 140 is disposed in the main body 110 and controls the plurality of direction display units 120 to display at least one of the direction in which the main body 110 can move during a cosmetic treatment and the direction in which the main body 110 is moving during a cosmetic treatment. The control unit 140 may include at least one processor, memory element, etc. capable of storing and processing data.

[0046] For example, if the direction display unit 120 includes a direction display light source, the control unit 140 may control the direction display light source indicating the direction to be displayed to light up or flash, and the direction display light sources indicating other directions to remain off. This allows the user to recognize the direction in which the main body 110 can move or the direction in which the main body 110 is moving through the light emitted by the light source.

[0047] The control unit 140 may determine a direction in which the main body 110 can move so that the main body 110 does not perform duplicate treatments on the same area of ​​the skin S during a cosmetic treatment based on the detection information of the displacement detection unit 130. As described above, the cosmetic treatment device 100 according to an embodiment of the present invention may irradiate high frequency waves, a laser, etc. onto the user's skin S. However, excessive irradiation of the high frequency waves or the laser onto the same area of ​​the skin S may cause side effects such as burns or pigmentation. To prevent such side effects, the control unit 140 may determine a direction in which the main body 110 can move so that duplicate treatments on the same area of ​​the skin S can be avoided during a cosmetic treatment. The control unit 140 controls the direction display unit 120 to notify the user of the determined direction in which the main body 110 can move.

[0048] In this regard, the control unit 140 may cumulatively determine the displacement of the main body 110 after the start of the cosmetic treatment. The control unit 140 calculates the relative position between the start position of the cosmetic treatment and the current position of the main body 110 using the sensing information of the displacement sensing unit 130, and based on this, may determine a direction in which the main body 110 moves toward an area of ​​the user's skin S that has already been treated as a direction in which the main body 110 cannot proceed, and may determine a direction in which the main body 110 can avoid performing a duplicate treatment on the same area of ​​the skin S as a direction in which the main body 110 can proceed.

[0049] The control unit 140 may generate a warning signal when it determines that the main body 110 is performing an overlapping treatment on the same area of ​​the user's skin S. The warning signal may be generated in the form of a control signal for the direction display unit 120 or a control signal for the warning output unit 150, which will be described later.

[0050] In this case, if the warning signal is generated in the form of a control signal for the direction display unit 120, the control unit 140 may control the direction display unit 120 to output the warning signal. For example, the control unit 140 may control the direction display unit 120 to blink all light sources included in the direction display unit 120 at a predetermined period in response to the warning signal.

[0051] The control unit 140 may cumulatively determine the number of times that the same area of ​​the skin S has been treated repeatedly, and may increase at least one of the intensity and frequency of the warning signal as the number of times that the same area has been treated repeatedly increases. For example, if the control unit 140 determines that the user has treated a predetermined area of ​​the skin S twice during a cosmetic treatment, it may generate a warning signal with a relatively low intensity or frequency, and if it determines that the predetermined area has been treated three or more times, it may generate a warning signal with a high intensity or frequency.

[0052] The control unit 140 may determine with relatively high accuracy whether or not a duplicate treatment has been performed on the same body part when the body part of the user to be treated is a first body part, and may determine with relatively low accuracy whether or not a duplicate treatment has been performed on the same body part when the body part is a second body part. For example, the first body part may include the user's face, and the second body part may include one or more of the user's thighs, abdomen, and buttocks.

[0053] The user's face is a part of the body where the skin is thin and scars from burns, etc., can have a significant impact on daily life. Such a relatively sensitive part of the user's body can be classified as the first part, and when a cosmetic treatment is performed on the first part, the control unit 140 can determine with relatively high accuracy whether or not a duplicate treatment has been performed and accurately provide a warning against the duplicate treatment, thereby minimizing side effects.

[0054] In contrast, the user's thighs, buttocks, etc. have relatively thick skin, and even if side effects occur, the impact on daily life is relatively small. Such relatively insensitive body parts of the user can be classified as the second part, and when a cosmetic treatment is performed on the first part, the control unit 140 determines whether or not a duplicate treatment has occurred with relatively low precision and provides a less strict warning about the duplicate treatment, so that the cosmetic treatment can be performed as much as possible according to the user's desired route.

[0055] In addition, the control unit 140 may determine the direction in which the main body 110 is to be moved by the user during the cosmetic treatment using the sensing information of the displacement sensing unit 130, and may control the direction display unit 120 to notify the user of the direction in which the main body 110 is to be moved. In accordance with such control by the control unit 140, the direction display unit corresponding to the direction in which the main body 110 is moving displays the direction, and the user may receive feedback on the direction in which the main body 110 is moving.

[0056] The warning output unit 150 outputs the warning signal under the control of the control unit 140. As described above, the warning signal generated by the control unit 140 may be in the form of a control signal for the direction display unit 120, but may also be generated in other forms. For example, the warning signal may include one or more of vibration and sound. The warning output unit 150 may output a warning signal in such a form.

[0057] 2, the warning output unit 150 may be a speaker. In this regard, the warning signal may be in the form of a sound or voice notification. The warning signal may also be in the form of a vibration, in which case the warning output unit 150 may be a vibrator.

[0058] An example of the operation of the cosmetic treatment device 100 according to one embodiment of the present invention will now be described in detail.

[0059] FIG. 5 is a diagram illustrating an example of a cosmetic treatment device according to an embodiment of the present invention operating in a normal mode.

[0060] 5, a cosmetic treatment device 100 according to an embodiment of the present invention is performing a cosmetic treatment on a user's skin S. The cosmetic treatment device 100 has moved from a start position P0, where the cosmetic treatment began, to a first position P1, a second position P2, and a third position P3 on the user's skin S, and is currently located at a fourth position P4. At the fourth position P4, the control unit 140 determines the next direction in which the cosmetic treatment device 100 can move.

[0061] Based on the orientation of the main body 110 of the cosmetic treatment device 100 at the fourth position P4, the front and left sides of the main body 110 are areas where cosmetic treatment has already been performed. When the cosmetic treatment device 100 moves from the fourth position P4 to the front or left side of the main body 110, a duplicate treatment to the first position P1 or the third position P3 is performed. Therefore, the direction in which the main body 110 can move from the fourth position P4 after the cosmetic treatment can be determined to be the rear or right side of the main body 110. Based on this determination, the control unit 140 controls the second direction display unit 122, which displays the rear of the main body 110, and the fourth direction display unit 124, which displays the right side of the main body 110, to notify the user that the cosmetic treatment device 100 should be moved to the rear or right side of the main body 110.

[0062] In addition, when the user moves the cosmetic treatment device 100 forward or leftward from the main body 110 at the fourth position P4, the control unit 140 may generate a warning signal. The generated warning signal may be output via the direction display unit 120 or the warning output unit 150. 6 is a diagram illustrating an example of an active mode operation of a cosmetic treatment device according to an embodiment of the present invention, where the active mode refers to a mode in which the direction of movement of the main body 110 is actively guided during cosmetic treatment.

[0063] In the active mode, the control unit 140 can control the plurality of direction display units 120 to be provided with a set path along which the main body 110 should proceed while avoiding overlapping treatments on the same area of ​​the user's skin S during the cosmetic treatment, and to display the direction along which the main body 110 should proceed during the cosmetic treatment based on the set path and the sensing information of the displacement sensing unit 130.

[0064] 6, a preset path R for performing a cosmetic treatment on a predetermined area of ​​a user's skin S is set to extend from a cosmetic treatment start position P0 through a first position P1 to a seventh position P7 to an eighth position P8. The control unit 140 controls the plurality of direction display units 120 to guide the movement path of the cosmetic treatment device 100 during the cosmetic treatment based on the preset path R.

[0065] First, the control unit 140 controls the first direction display unit 121 located in front of the main body 110 to display the forward direction of the main body 110 so that after the cosmetic treatment is performed at the cosmetic treatment start position P0, the user is guided to proceed to the first position P1 located in front of the main body 110.

[0066] Next, after the cosmetic treatment is performed at the first position P1, the control unit 140 controls the first direction display unit 121 located at the front of the main body 110 to display the forward direction of the main body 110 so that the user is guided to proceed to the second position P2 located at the front side of the main body 110.

[0067] In addition, after the cosmetic treatment is performed at the second position P2, the control unit 140 controls the fourth direction display unit 124 located on the right side of the main body 110 to display the right direction of the main body 110 so that the user is guided to proceed to the third position P3 on the right side of the main body 110.

[0068] In addition, after the cosmetic treatment is performed at the third position P3, the control unit 140 controls the fourth direction display unit 124 located on the right side of the main body 110 to display the right direction of the main body 110 so that the user is guided to proceed to the fourth position P4 on the right side of the main body 110.

[0069] In addition, after the cosmetic treatment is performed at the fourth position P4, the control unit 140 controls the second direction display unit 122 located at the rear of the main body 110 to display the rear direction of the main body 110 so that the user is guided to proceed to the fifth position P5 located at the rear of the main body 110.

[0070] In addition, after the cosmetic treatment is performed at the fifth position P5, the control unit 140 controls the third direction display unit 123 located on the left side of the main body 110 to display the left direction of the main body 110 so that the user is guided to proceed to the sixth position P6 on the left side of the main body 110.

[0071] In addition, after the cosmetic treatment is performed at the sixth position P6, the control unit 140 controls the second direction display unit 122 located at the rear of the main body 110 to display the rear direction of the main body 110 so that the user is guided to proceed to the seventh position P7 located at the rear of the main body 110.

[0072] Finally, after the cosmetic treatment is performed at the seventh position P7, the control unit 140 controls the fourth direction display unit 124 located on the right side of the main body 110 to display the right direction of the main body 110 so that the user is guided to proceed to the eighth position P8 on the right side of the main body 110.

[0073] In this way, the control unit 140 guides the direction of travel of the cosmetic treatment device 100 along the set route R, so that the user can avoid performing overlapping treatments on the same area of ​​the skin S, and can perform the cosmetic treatment safely.

[0074] In the active mode, if the cosmetic treatment device 100 deviates from the guidance along the set path R and moves in a direction that would cause the same area of ​​the user's skin S to be treated multiple times, the control unit 140 may generate a warning signal. The generated warning signal may be output via one or more of the direction display unit 120 and the warning output unit 150.

[0075] In relation to the active mode, the cosmetic treatment device 100 according to an embodiment of the present invention may further include a memory unit 160 disposed in the main body 110 and configured to store one or more preset paths according to a setting standard. The memory unit 160 may be configured with various memory devices that store one or more preset paths.

[0076] In addition, the cosmetic treatment device 100 according to an embodiment of the present invention may further include a communication unit 170 disposed in the main body 110 and configured to receive the set route from an external device. For example, the communication unit 170 may receive the set route from a mobile device such as a smartphone using a short-range wireless communication method.

[0077] In one embodiment of the present invention, both the storage unit 160 and the communication unit 170 may be provided, or only one of the two may be provided.
