Description

beauty devices

[0001] The present invention relates to a beauty device.

[0002] Human skin can be contaminated by external activities, and wrinkles can form due to aging, hormonal changes, and other factors. With the recent rise in interest in skin care, cleansing devices capable of effectively removing skin contaminants, as well as various devices for skin beauty and anti-aging, are being developed.

[0003] For example, devices that provide high-frequency and infrared energy to the skin are being developed. These devices apply thermal energy to the skin, and by applying thermal energy to the skin, they can improve the elasticity of the applied skin area or effectively deliver beauty products into the skin.

[0004] In addition, devices that deliver sound waves and light to the skin are being developed. For example, sonophoresis and laserporation devices are being developed that utilize ultrasound or laser light to deliver cosmetic products into the skin. These devices can create pathways for the injection of cosmetics into the skin using ultrasound or laser light, thereby increasing the penetration rate of cosmetic products.

[0005] In addition, devices that physically deliver cosmetic products to the skin using low current are being developed. For example, these devices utilize iontophoresis, electroporation, and electroosmosis, and are capable of effectively delivering active ingredients into the skin by applying current to charged or neutral cosmetic products.

[0006] In other words, various devices capable of providing skin care and anti-aging functions using light energy, sound waves, electric current, vibration, etc., are being developed.

[0016] Specifically, the control unit turns on the power when a preparation mode in which the main body is separated from the charging unit is detected, and turns off the power when a usage mode in which the active part contacts the skin in the preparation mode is not detected for a second time that is relatively longer than the first time.

[0033] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0034] FIG. 1 is a block diagram of a beauty device according to one embodiment of the present invention, and FIG. 2 is a partial block diagram of a beauty device according to one embodiment of the present invention.

[0035] FIGS. 3 and 4 are perspective views of the main body of a beauty device according to one embodiment of the present invention, FIG. 5 is a perspective view of the charging part of a beauty device according to one embodiment of the present invention, and FIG. 6 is a perspective view showing the charging of a beauty device according to one embodiment of the present invention.

[0036] In addition, FIG. 7 is a perspective view showing the mounting of a beauty device according to one embodiment of the present invention, FIG. 8 is a partial perspective view showing the mounting of a beauty device according to one embodiment of the present invention, and FIG. 9 is a flowchart of the operation sequence of a beauty device according to one embodiment of the present invention.

[0037] Referring to FIGS. 1 to 9, a beauty device (1) according to the first embodiment of the present invention is a tool that implements a beauty function by contacting the skin, and includes a main body (10), an operating part (20), a power supply part (40), a control part (50), a sensing part (60), a charging part (70), etc.

[0038] The main body (10) forms the part that the user holds. The main body (10) may be equipped with an operating part (20), a power supply part (40), a control part (50), a sensing part (60), etc., which will be described later, and some components of the above configuration, such as the operating part (20), may be provided to be exposed to the outer surface of the main body (10).

[0039] The main body (10) may have a rod shape that allows the user to grip it conveniently and stably. In this case, the length direction of the main body (10) may also be interpreted as the height direction, etc. The main body (10) may have the shape of a rod with a circular cross-section, and the cross-section may have a relatively constant shape along the length direction. Of course, to improve the user's grip, the cross-section of the main body (10) may change along the length direction, and for example, the main body (10) may have a curved structure on which fingers, etc. can rest.

[0040] The main body (10) may form a handle (11) so that the user can grip it. The main body (10) may have the shape of a rod with a circular cross-section, and an operating part (20), etc. may be provided on one side of the main body (10). In this case, the user can use the beauty device (1) while holding the lower part of the main body (10).

[0041] In the case of some publicly available beauty devices, they have an overly complex appearance due to a focus on multifunctionality, which results in unnatural usage and requires users to do a lot of learning to use the product. On the other hand, the main body (10) of the present invention is designed based on user behavior analysis, so that behavior can be induced by design elements even without the user learning how to use the product. That is, the main body (10) has a rod shape that the user can intuitively hold and use, thereby allowing the user to learn how to use it comfortably and intuitively.

[0042] The main body (10) may be provided with a display unit (not shown in the symbol). The display unit may display the operating status of the operating unit (20), the charging status of the power supply unit (40), etc. The display unit may include an LED, etc. provided in the main body (10).

[0043] The main body (10) may be provided with a charging terminal (not shown) for charging a power supply unit (40) provided inside. The charging terminal may be positioned on one side of the main body (10) spaced apart from the operating unit (20). Additionally, the main body (10) may be formed with a structure that allows the power supply unit (40) to be charged via wireless charging, such as an electromagnetic induction method, while mounted on the charging unit (70).

[0044] A button (51), which will be described later, may be provided on the main body (10), and the power can be turned on and off using the button (51). After the user turns the power on, the power may be automatically turned off after the set usage time has elapsed. At this time, whether the operating part (20) is in contact with the skin may be detected by the detection part (60), and the control part (50) may automatically perform power standby and power off based on the detection signal of the detection part (60). Such power standby and power off are intended to prevent unnecessary power consumption and to maximize the usable time from full charge to discharge.

[0045] The main body (10) may have an electrode (21) of the working part (20) provided at one end. Based on FIG. 3, the electrode (21) may be provided at the bottom of the main body (10), and the first electrode (21a) and the second electrode (21b) may be arranged in a concentric circle shape. A rim (22) is provided on the outer side of the second electrode (21b), but it is also possible to add a third electrode. In addition, the first electrode (21a) may be circular or ring-shaped.

[0046] A mounting portion (12) may be provided at the other end opposite to the one end where the working portion (20) is provided on the main body (10). The mounting portion (12) may be provided in the shape of a ring, and the ring may be positioned vertically on the main body (10).

[0047] The mounting member (12) can be positioned to be attached to a mounting bracket (72) provided in the charging unit (70). The mounting bracket (72) may have a rod shape that extends relatively horizontally or at an angle, and the mounting member (12) of the main body (10) can be positioned so that the main body (10) is attached to the mounting bracket (72) by its own weight as the mounting bracket (72) passes through it.

[0048] The mounting member (12) may have a ring shape in addition to a ring, and various shapes that can be mounted on the mounting base (72) are possible. It is also possible for the main body (10) to be mounted on the charging unit (70) by attaching the mounting member (12) to the mounting base (72) using a magnet, and in this case, the detection unit (60) can detect whether the main body (10) is mounted using magnetism. Of course, even if the mounting member (12) and the mounting base (72) have the shape as shown in the drawing, the detection unit (60) can confirm that the main body (10) is mounted on the charging unit (70) through magnetism by using a magnetic material / metal material, etc., in at least one of the mounting member (12) and the mounting base (72).

[0049] A portion of the mounting detection sensor (63) may be provided in the mounting member (12), and for example, the detection part (63a) of the mounting detection sensor (63) may be built into the mounting member (12). Additionally, as will be described later, a detection part (63b) may be provided in the mounting base (72) in conjunction with the detection part (63a).

[0050] The action part (20) is provided on the main body (10) and transmits power by contacting the skin. The action part (20) is provided on one side of the main body (10) and may be exposed to the outside. The action part (20) can apply one or more mechanisms to the skin; for example, the action part (20) can apply mechanisms such as electroporation (EP), ultrasound (US), and radio frequency (RF) to the skin.

[0051] The working part (20) may include an electrode (21) that contacts the skin and transmits power to the skin. The electrode (21) is provided so that its polarity can be changed by the control part (50), and two or more electrodes may be provided in a spaced-apart configuration.

[0052] The working part (20) can apply two or more types of mechanisms to the skin using two or more electrodes (21). For example, an electroporation mechanism can be applied to the skin through one electrode (21), and an ultrasonic mechanism can be applied to the skin through another electrode (21). The working part (20) can achieve various cosmetic effects by utilizing two or more electrodes (21) and two or more types of mechanisms.

[0053] When the working part (20) applies the electroporation mechanism to the skin, the skin may have an active ingredient applied to it. That is, the working part (20) may come into contact with the skin in a state where the active ingredient is not applied or where the active ingredient is applied.

[0054] The working part (20) may include a first electrode (21a), a second electrode (21b), etc. The first electrode (21a) may be provided at the center on the surface of the working part (20). The first electrode (21a) may be provided at the center of the longitudinal centerline of the handle (11). That is, the center of the first electrode (21a) may be located on the longitudinal centerline of the handle (11). The first electrode (21a) may be a circular electrode (21) located on the longitudinal centerline of the handle (11), or a ring-shaped electrode (21) with a hollow center.

[0055] The second electrode (21b) may be arranged to surround the first electrode (21a). The second electrode (21b) may be spaced apart from the first electrode (21a) and arranged in a substantially concentric shape. That is, the central axis of the second electrode (21b) and the central axis of the first electrode (21a) may be parallel.

[0056] One or more second electrodes (21b) may be provided. That is, ring-shaped second electrodes (21b) may be spaced apart around the circumference of a circular first electrode (21a). However, the ring-shaped electrode (21) provided on the outer side of the first electrode (21a) may be defined as the second electrode (21b), and the electrode (21) provided on the outer side of the second electrode (21b) may be defined as the third electrode. It is also possible to provide a fourth electrode around the circumference of the third electrode.

[0057] A rim (22) may be provided around one or more second electrodes (21b) in the working portion (20). The rim (22) may be provided on the outer side of the electrode (21). The rim (22) may form a ring shape and may be provided vertically parallel to the side of the handle (11). That is, the handle (11) and the working portion (20) can be continuously and smoothly connected without any step.

[0058] The electrode (21) of the working part (20) transmits electricity to the skin while in contact with the skin, and can form an electrical path within the skin based on the polarity of the electrodes (21). When the working part (20) comes into contact with the skin, an electrical loop can be formed, and whether the working part (20) is in contact with the skin can be detected based on the resistance or impedance within the loop. This will be explained again below in the sensing part (60).

[0059] The power supply unit (40) stores power. The power supply unit (40) may include a rechargeable battery. The power supply unit (40) may be positioned at the bottom within the main body (10) and may be charged via wired or wireless charging through the charging unit (70) described later.

[0060] The power from the power supply unit (40) is transferred to the working unit (20) so that the electrode (21) applies the mechanism to the skin, and the voltage of the power transferred from the power supply unit (40) to the working unit (20) can be adjusted.

[0061] The control unit (50) is provided in the main body (10) and controls the working unit (20), etc. The control unit (50) can control the mechanism by which the electrode (21) included in the working unit (20) is applied to the skin. The control unit (50) can change the mechanism of the working unit (20) and can selectively control at least one of electroporation (EP), ultrasound (US), and radio frequency (RF).

[0062] The control unit (50) may include a button (51) provided on the main body (10), and control can be implemented through a pre-assigned process as the user presses the button (51). At this time, the button (51) may be provided as a touch type or a pressure type, and at least one or more may be provided. One button (51) may control the power on / off, and the other button (51) may control the switching of the mechanism. Of course, the operation of the button (51) may not be limited to this. In addition, the button (51) may be omitted, and voice recognition or automatic operation based on skin contact may also be possible.

[0063] Of course, as the working part (20) includes two or more electrodes (21), the control part (50) may allow two or more mechanisms to be applied to the skin simultaneously by the working part (20). That is, the control part (50) may change the mechanism of the working part (20) or adjust the electrical energy, etc., that the working part (20) delivers to the skin, by taking into account the usage state of the working part (20).

[0064] Additionally, the control unit (50) may utilize a humidity sensor (not shown) that may be provided in the main body (10). The control unit (50) may adjust the output of the operating unit (20) according to the humidity of the space in which the present invention is used.

[0065] The control unit (50) can selectively control the mechanism of the working unit (20) as electroporation, and the control unit (50) can adjust the pulse width of the electroporation differently according to the change in resistance of the skin that the working unit (20) contacts. In addition, the control unit (50) can output the voltage of the working unit (20) in a complex pattern.

[0066] The control unit (50) can significantly reduce standby power consumption by minimizing standby time through automatic control of the operation of the power supply and operating unit (20) by considering whether the main body (10) is charged or mounted.

[0067] That is, the beauty device (1) according to the present embodiment can prevent unnecessary power consumption by the control unit (50) controlling the power supply unit (40) and the operating unit (20) according to the mode. For example, the control unit (50) can control the power on / off and operation of the operating unit (20) depending on the state of the main body (10) with respect to the charging unit (70) and whether the operating unit (20) is in contact with the skin. This will be explained in detail below.

[0068] The sensing unit (60) can detect the operating state of the working unit (20), the power or charging state of the power supply unit (40), and the condition of the skin. That is, the sensing unit (60) can not only check the status of the components installed within the main body (10), but also detect the real-time condition of the skin that the working unit (20) contacts.

[0069] The detection unit (60) can detect the charging status of the power supply unit (40). The detection unit (60) can check the electrical connection between the power supply unit (40) and the charging unit (70) using a charging detection sensor (61). Alternatively, the charging detection sensor (61) of the detection unit (60) can detect the state of the charging unit (70) and the main body (10) using magnetism. That is, the detection unit (60) can detect the electrical connection with the charging unit (70) in preparation for wired charging, or detect the state of the main body (10) using magnetism in preparation for wireless charging.

[0070] The charging detection sensor (61) of the detection unit (60) may include metal to detect magnetism, and the part of the main body (10) corresponding to the charging detection sensor (61) may be made of a material that is affected by magnetism.

[0071] As previously explained, a charging terminal may be provided in the main body (10), and the sensing unit (60) can detect whether the charging terminal provided in the main body (10) is electrically connected to the charging unit (70) to detect the charging mode. Alternatively, the sensing unit (60) can recognize the charging mode by detecting the adjacent arrangement between the wireless charging structure formed in the main body (10) and the charging unit (70) using magnetism or the like.

[0072] As described above, the detection unit (60) can detect that the beauty device (1) is placed in a charging mode based on the electrical connection between the power supply unit (40) and the charging unit (70) built into the main body (10), or the magnetic connection between the charging unit (70) and the main body (10). In addition, the detection unit (60) can recognize the charging mode by utilizing structural interlocking. For example, a protrusion (not shown) that is elastically supported is provided on the charging unit (70), and when the main body (10) is placed on the charging unit (70) for charging, the detection unit (60) can confirm entry into the charging mode through a structural deformation in which the protrusion is pressed by the outer surface of the main body (10).

[0073] Additionally, the sensing unit (60) can detect whether the working unit (20) is in contact with the skin. When the electrode (21) included in the working unit (20) is in contact with the skin, the sensing unit (60) can detect whether the working unit (20) is in contact with the skin based on the loop formed between the electrode (21) of the working unit (20) and the skin.

[0074] Additionally, the detection unit (60) can detect whether the working unit (20) has entered a usage mode in contact with the skin based on the impedance level in the working unit (20). The detection unit (60) can apply a low-voltage pulse through the working unit (20) to measure the impedance of the skin tissue. By measuring the impedance based on the low-voltage pulse applied to the skin, the detection unit (60) can detect whether the working unit (20) is separated from the skin.

[0075] If the impedance level detected by the sensing unit (60) is sufficiently high (above a preset value), it can be considered that the working unit (20) is not in contact with the skin. On the other hand, if the impedance level detected by the sensing unit (60) is confirmed to be below the preset value, it can be presumed that the skin is in contact with the working unit (20). The impedance level can be determined at the surface of the electrode (21) of the working unit (20).

[0076] Of course, since the sensing unit (60) can detect whether the working unit (20) is in contact with the skin by utilizing both alternating current and direct current, the impedance and resistance can be interchanged.

[0077] Alternatively, the sensing unit (60) can determine whether the working unit (20) is in contact with the skin based on the current flow between the plurality of electrodes (21) included in the working unit (20). For example, the sensing unit (60) can detect that the working unit (20) is in contact with the skin if the degree of current flow between the plurality of electrodes (21) exceeds a threshold point.

[0078] The sensing unit (60) can detect whether the operating unit (20) has entered a usage mode in which it contacts the skin by using various methods in addition to resistance, impedance, and current flow. The sensing unit (60) may have a skin sensing sensor (62) for confirming skin contact, and the skin sensing sensor (62) may be a sensor that measures electrical physical properties without limitation.

[0079] Additionally, the sensing unit (60) can detect a change in loop resistance regarding the electrical loop formed between the working unit (20) and the skin. Through this, the sensing unit (60) can determine whether the liquid, which is an active ingredient, has been applied to the surface of the skin to which the working unit (20) contacts. For example, the sensing unit (60) can estimate that the active ingredient has been applied to the skin if the loop resistance decreases, while it can estimate that the active ingredient has been reduced or removed from the surface of the skin if the loop resistance increases.

[0080] That is, the sensing unit (60) can determine whether an active ingredient has been applied between the skin and the working unit (20) (at least one side of the surface of the skin and the electrode (21) of the working unit (20)) based on changes in resistance, etc., and this determination can be used to uniformly control the active energy delivered to the skin.

[0081] Additionally, the sensing unit (60) can detect the temperature of the skin. The temperature of the skin can be detected using a temperature sensor (not shown) that may be provided adjacent to the working unit (20). Of course, the sensing unit (60) may further include sensors capable of detecting conditions such as humidity, moisture content, and pH in addition to the temperature of the skin.

[0082] The detection unit (60) may include a mounting detection sensor (63) that detects whether the main body (10) is mounted on the charging unit (70). The mounting detection sensor (63) includes a detection unit (63a) and a detection unit (63b), and detection may occur when the detection unit (63a) is located adjacent to the detection unit (63b).

[0083] For example, the detection unit (63a) may be provided in the mounting unit (12). The detection unit (63a) may be built into the mounting unit (12) as a configuration for detecting whether the main body (10) is placed in a mounting mode that is mounted on the mounting base (72) of the charging unit (70).

[0084] The mounting detection sensor (63) may be a magnetic sensor, and the mounting base (72) may have a magnetic material applied as a detection part (63b). When the mounting end (12) of the main body (10) is mounted on the mounting base (72), the detection part (63a) is positioned adjacent to the detection part (63b), so the mounting detection sensor (63) can check whether the main body (10) is mounted.

[0085] The detection portion (63a) of the mounting detection sensor (63) may be provided in at least a portion of the main body (10) according to the sensor specifications. That is, the detection portion (63a) is not limited to being provided in the mounting section (12) as in the drawing.

[0086] Alternatively, as previously mentioned, the sensing part (63a) and the part to be detected (63b) may be arranged so as to be opposite. For example, a magnetic material or the like may be applied to the mounting section (12), and a sensor (not shown) for detecting mounting may be provided on the mounting base (72).

[0087] The charging unit (70) charges the power unit (40) on which the main body (10) is mounted. The charging unit (70) may include a charging stand (71) and a mounting stand (72). The charging stand (71) can charge the power unit (40) of the main body (10). Before describing the charging unit (70), the main body (10) that is mounted on or charged in the charging unit (70) will be described.

[0088] As shown in Fig. 7, when the mounting member (12) is attached to the mounting bracket (72), the working part (20) of the main body (10) may be suspended from the charging part (70) while separated from the charging bracket (71). In this case, the main body (10) can be interpreted as being placed in a mounting mode.

[0089] On the other hand, as shown in FIG. 6, when the mounting member (12) is not caught on the mounting bracket (72) and the working part (20) is seated on the charging bracket (71), the charging part (70) can transmit power to the power supply part (40) of the main body (10). At this time, the main body (10) may be in a charging mode.

[0090] That is, in this embodiment, the main body (10) can be selectively placed in either a mounting mode in which it is mounted on a stand (72) of the charging unit (70) or a charging mode in which the power unit (40) is charged by the charging stand (71) of the charging unit (70).

[0091] The charging unit (70) is described in detail below. The charging unit (70) may include a charging stand (71) that charges the power supply unit (40) of the main body (10) and a mounting stand (72) that fixes one side of the main body (10). The charging stand (71) may have a recessed shape to accommodate at least a part of the working part (20), or it may have a ring shape through which at least a part of the working part (20) passes. The central part of the charging stand (71) may have a chamfered perimeter so that the working part (20) can be smoothly inserted. When the working part (20) is inserted into the charging stand (71), power can be transferred from the charging stand (71) to the power supply unit (40) of the main body (10) based on an electrical terminal connection or a wireless connection.

[0092] A protective tip (not shown in the drawing) for protecting the electrode (21) of the working part (20) may be provided on the bottom of the part in which the working part (20) is accommodated in the charging stand (71). The protective tip may be made of an elastic or soft material, and can protect the electrode (21) of the working part (20) when the main body (10) is placed on the charging stand (71) and the power supply (40) is charged.

[0093] Additionally, the charging stand (71) may be provided with a display unit (not shown) that indicates whether the main body (10) is properly seated and how much charging has been done. Alternatively, the charging status may be indicated using a display unit provided on the main body (10), but the display unit on the charging stand (71) may be omitted.

[0094] When the main body (10) is placed on the charging stand (71), the detection unit (60) can detect the electrical connection between the power supply unit (40) and the charging stand (71) or the start of charging by the power supply unit (40), thereby detecting that the main body (10) has entered a charging mode. Additionally, the detection unit (60) can detect that the charging mode has ended when the main body (10) is separated from the charging stand (71).

[0095] The mounting bracket (72) may be provided to extend upward from the charging stand (71). The mounting bracket (72) may have a roughly L-shaped form including a vertical part and a horizontal part, and the vertical part may have a height higher than the main body (10) so that the main body (10) is not inserted into the charging stand (71) when mounted on the mounting bracket (72). The mounting end (12) of the main body (10) may be caught on the horizontal part of the mounting bracket (72), and a bending point may be formed on the horizontal part of the mounting bracket (72) so that the mounting end (12) is seated thereon, so that shaking of the main body (10) is minimized while the mounting end (12) is caught.

[0096] A detection part (63b), such as a magnet, may be attached or embedded in the horizontal portion of the mounting bracket (72) over which the mounting member (12) rests. At this time, the mounting member (12) may be made of a metal material, and the detection part (60) can detect that the main body (10) is placed in a mounting mode by detecting the magnetism of the detection part (63b) provided on the mounting bracket (72) when the main body (10) is mounted on the mounting bracket (72).

[0097] The automatic control of the control unit (50) according to the mode is described below with reference to FIG. 9. First, when the main body (10) is mounted on the charging unit (70), that is, when the mounting end (12) of the main body (10) is mounted on the mounting stand (72), the mounting detection sensor (63) can detect that the main body (10) is mounted through the detection unit (63a) provided on the mounting end (12) of the main body (10) and the detection unit (63b) provided on the mounting stand (72) of the charging unit (70). Through this, the control unit (50) can recognize that the main body (10) is mounted on the charging unit (70) and determines that the main body (10) is placed in the mounting mode.

[0098] The control unit (50) can switch the power from On to Off or maintain the Off state when the stand mode is detected. The state in which the main body (10) is hung on the stand (72) can be presumed to be a state in which the user places the main body (10) on the charging unit (70) and applies an active ingredient to the skin. In this case, the main body (10) does not come into contact with the skin for at least a certain period of time, and the electrode (21) does not need to operate, so the control unit (50) can turn off the power in the stand mode to suppress the execution of the mechanism of the action unit (20).

[0099] However, if the main body (10) is detected by the detection unit (60) to be separated from the charging unit (70), the control unit (50) may determine that the main body (10) has entered a preparation mode. When entering a preparation mode, the control unit (50) may turn on the power and prepare to execute the mechanism of the operating unit (20).

[0100] However, even if the power is turned on, the working part (20) does not operate immediately, and the execution of the mechanism of the working part (20) may be delayed when the electrode (21) of the working part (20) is not in contact with the skin.

[0101] When the detection unit (60) detects that the working part (20) is in contact with the skin in the ready mode with the power turned on, the control unit (50) recognizes that the main body (10) has entered the usage mode. When the control unit (50) detects the usage mode, it can execute the mechanism of the working part (20) to allow effective energy to be delivered to the skin through the electrode (21).

[0102] However, if the working part (20) does not come into contact with the skin during the preparation mode, unnecessary power consumption may occur simply by maintaining the power on. That is, when the power is turned on, internal components are activated so that output can be immediately emitted through the working part (20), thereby consuming power from the power supply unit (40). Therefore, it is necessary to verify whether the mechanism of the working part (20) needs to be executed and to block power consumption.

[0103] Accordingly, the control unit (50) may maintain the operation of the working unit (20) in a stopped state if the transition from the preparation mode to the usage mode in which the working unit (20) contacts the skin is not detected during the first time period. Here, the stopped state may mean a state in which the power is turned on but consumes only a minimum amount of power and the operation of the working unit (20) may not be initiated immediately. Maintaining the working unit (20) in a stopped state may be interpreted as a standby mode. At this time, the first time period may be within 5 seconds or within 1 second.

[0104] The control unit (50) may turn off the power if, when the main body (10) is in standby mode, it is not detected whether the working unit (20) is in contact with the skin for a second period of time. At this time, the second period may be a relatively longer period than the first period, for example, 20 seconds or more, or 60 seconds or more.

[0105] The control unit (50) can presume that in the case where the switch from standby mode to usage mode is not made for a second period of time, the user has separated the main body (10) from the charging unit (70) but has no intention of using it immediately on the skin. For example, this may be a case where the user takes the main body (10) out of the charging unit (70) but places the main body (10) on a vanity table, etc., for reasons such as applying an active ingredient to the skin.

[0106] When the main body (10) is separated from the charging unit (70), the use of the working unit (20) is prepared, but if the working unit (20) does not come into contact with the skin for several tens of seconds, the control unit (50) can turn off the power to minimize standby power consumption.

[0107] The control unit (50) may switch to standby mode if a transition from the ready mode to the usage mode is not detected. However, if contact of the electrode (21) with the skin is detected in the standby mode, the transition from the standby mode to the usage mode may be made immediately without passing through the ready mode. Of course, compared to the transition from the ready mode to the usage mode, there may be some delay in the output of effective energy from the electrode (21) of the operating unit (20) when transitioning from the standby mode to the usage mode, but since this is not to a degree that the user can perceive, it may not be a problem for usability.

[0108] That is, the control unit (50) can automatically switch between a mounting mode, a ready mode, a standby mode, a usage mode, and a power off state based on the result of detecting the mounting of the mounting unit (12) or skin contact of the operating unit (20) through the detection unit (60). Through this, the control unit (50) can reduce power consumption and extend the lifespan of the operating unit (20) while maximizing its usage time.

[0109] In addition, power consumed during detection by the detection unit (60) can also be reduced. For example, the detection unit (60) can detect modes intermittently at regular intervals through the skin detection sensor (62) and the mounting detection sensor (63), and some sensors may be deactivated for each mode. For example, in the case of the mounting mode, the operation of the skin detection sensor (62) may be turned off.

[0110] FIG. 10 is a flowchart of the operation of a beauty device according to another embodiment of the present invention.

[0111] Referring to FIG. 10, in the case of a beauty device (1) according to another embodiment of the present invention, control based on a mounting mode and a charging mode may be performed. Hereinafter, the present embodiment will be described mainly in terms of how it differs from the previous embodiment, and any parts omitted from the description will be replaced by the previous content. As previously described, the charging unit (70) includes a mounting stand (72) and a charging stand (71). In this embodiment, in addition to the mounting mode in which the main body (10) is mounted on the mounting stand (72), control for a charging mode in which the operating unit (20) is inserted into the charging stand (71) can be added. That is, the control unit (50) can implement automatic control by considering all charging modes in which the main body (10) is placed on the charging stand (71) in addition to the mounting mode in which the main body (10) is mounted on the mounting stand (72).

[0112] In the case where the sensing unit (60) of the main body (10) recognizes the charging unit (70), for example, when the sensing unit (60) detects that the main body (10) has entered a charging mode in which it is placed on a charging stand (71) to be charged, the control unit (50) can turn off the power and allow the power supply unit (40) to charge quickly. In particular, since there is no need for the electrode (21) of the operating unit (20) to operate in the charging mode, the operation of the operating unit (20) can be locked.

[0113] On the other hand, when the main body (10) is placed on the charging stand (71) and then separated from the charging stand (71), the control unit (50) can turn on the power of the main body (10). Since it can be inferred that the use of the operating unit (20) will occur immediately when the main body (10) exits the charging mode, the control unit (50) can turn on the power when the charging mode in which the main body (10) is placed on the charging stand (71) ends.

[0114] However, when the power of the main body (10) is turned on due to the end of the charging mode, if the detection unit (60) detects that the mounting portion (12) of the main body (10) is positioned over the mounting stand (72), the control unit (50) can detect that the main body (10) has entered the mounting mode and enter a standby mode that maintains the operation of the operating unit (20) in a stopped state.

[0115] Considering the shape of the charging unit (70), the user places the main body (10) on the charging stand (71) to charge the power unit (40), and once charging is complete, the main body (10) can be temporarily placed on the stand (72) to use the main body (10). The stand mode may be a state in which the user places the main body (10) from the charging stand (71) to the stand (72) and applies an active ingredient to the skin.

[0116] That is, in this embodiment, taking into account the user's expected usage pattern according to the shape of the charging unit (70), the control unit (50) turns on the power when the main body (10) exits the charging mode, but can be set to enter a standby mode by considering that the operation of the working unit (20) will not be performed for a certain period of time (such as the time for applying an active ingredient) when the main body (10) enters the docking mode.

[0117] In the case of the preceding embodiment, the power may be turned off in docking mode, whereas in the present embodiment, the power may be turned on in docking mode. That is, the present embodiment may consider the case where charging occurs before docking, and the docking mode may be treated the same as the standby mode.

[0118] On the other hand, when the power of the main body (10) is turned on following the end of the charging mode, if the detection unit (60) does not recognize the docking mode, the control unit (50) can control the main body (10) to enter the preparation mode. At this time, the preparation mode may be the same as the preparation mode described in the previous embodiment.

[0119] As described in the previous embodiment, just as the power is turned off when skin contact of the electrode (21) is not detected for a second time in standby mode, this embodiment allows the power to be turned off even when the main body (10) enters standby mode (standby mode) as it is mounted on the stand (72).

[0120] For example, if the situation in which the main body (10) does not detach from the stand (72) is maintained for a certain period of time in the stand mode, the control unit (50) can turn off the power. After that, when the main body (10) is separated from the stand (72), the control unit (50) can turn on the power to enter the ready mode.

[0121] That is, the control unit (50) may turn off the power if the preparation mode in which the main body (10) is separated from the stand (72) in the stand mode is not detected during the third time. At this time, the third time may be relatively longer than the first time, but relatively shorter than the second time. This is because in the case of the second time, the user may have placed the main body (10) on a vanity or the like and forgotten to use it, whereas in the case of the third time, the user may have hung the main body (10) on the stand (72) and prepared the mechanism of the action unit (20) (such as applying an active ingredient to the skin).

[0122] Of course, the first to third times can be appropriately set by considering various usage scenarios, and the first to third times can be reset by accumulating data in which the mode is switched according to the user's usage pattern and the control unit (50) learning the pattern of data switching.

[0123] In this embodiment, the charging unit (70) can implement a charging mode in which the main body (10) is placed on a charging stand (71) and a mounting mode in which the main body (10) is placed on a mounting stand (72), and the control unit (50) can automatically control the transition from the charging mode to the mounting mode, the transition from the charging mode to the ready mode, the transition from the mounting mode to the standby mode, etc., thereby minimizing power consumption.

[0124] Additionally, the present invention allows for the merging of a charging mode and a docking mode. The embodiment described through FIG. 9 is controlled in the order of docking mode - ready mode - standby mode / use mode, and the embodiment described through FIG. 10 is controlled in the order of charging mode - docking mode (standby mode) - ready mode - standby mode / use mode.

[0125] In addition, the present invention may include an embodiment in which the main body (10) enters a ready mode only when it is not placed on the charging stand (71) and is not mounted on the stand (72). This means that in order to enter the ready mode, it must not be in a mounting mode or a charging mode.

[0126] In this case, even if the main body (10) is separated from the charging stand (71), the power may not be turned on immediately, and the power may be turned on when conditions are confirmed that the main body is not mounted on the stand (72) for a relatively short period of time. The short period at this time may be a few seconds shorter than the first time (for example, within 2 seconds or within 3 seconds).

[0127] Considering the user's usage pattern, the user can take the main body (10) out of the charging stand (71) and immediately place it over the stand (72). This can be inferred as a situation where the user intends to use the main body (10) after it has been fully charged, but preparations such as the application of active ingredients are required.

[0128] Considering these circumstances, the control unit (50) may turn on the power only when both the charging mode and the docking mode have been exited in order to minimize power usage, thereby allowing entry into the preparation mode.

[0129] In addition, the present invention can determine various aspects such as power On / Off and entry into standby / prep mode, taking into account the user's usage conditions regarding charging mode and docking mode. The present invention includes all embodiments that can be easily modified by a person skilled in the art with respect to mode control.

[0130] In addition to the embodiments described above, the present invention encompasses all embodiments resulting from combinations of the embodiments and combinations of the embodiments and known technology.

[0131] Although the present invention has been described in detail through specific embodiments, this is for the purpose of specifically explaining the invention, and the invention is not limited thereto. It will be apparent that modifications or improvements can be made by those skilled in the art within the technical scope of the invention.

[0132] All simple variations or modifications of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be clarified by the appended claims.
