Description

Technical Field

[0001] This disclosure relates to a massage device, and more specifically, to a massage device configured to perform massage actions including lightcare. Background Technology

[0002] In modern society, due to factors such as aging populations, increased stress, and the chronicity of musculoskeletal diseases, the demand for relieving physical fatigue and managing health is growing. In response to this trend, there is a growing demand for massage equipment that can be easily used by individuals or at home, especially full-body massage devices such as massage chairs, and technological research and development in this area is actively underway.

[0003] Traditional massage devices (such as massage chairs) are designed to provide mechanical stimulation to multiple body parts, including the back, shoulders, neck, arms, waist, hips, legs, and feet. This stimulation is typically provided through functions such as rolling, kneading, patting, vibration, air pressure, or heat application, and can be adjusted within a certain range according to the user's body size or posture. However, most traditional devices rely on mechanical stimulation methods, which tend to be repetitive and fixed in intensity and pattern, limiting their ability to precisely address the user's skin condition, sensitivity, or the needs of specific areas.

[0004] Recently, various physical therapy techniques, such as magnetic field therapy, low-frequency electrical stimulation, and phototherapy, have been applied in hospitals and professional institutions, and their efficacy has been scientifically proven. In particular, phototherapy using near-infrared (NIR) or specific wavelengths of LED light is believed to improve skin elasticity, promote collagen production, improve scalp blood circulation, and activate hair follicles. Due to its painless, non-invasive nature and suitability for repeated application, this phototherapy technique is finding increasing application in the fields of beauty and rehabilitation medicine.

[0005] However, currently, the light irradiation technology described above is mainly provided in the form of fixed medical devices or beauty instruments. The above information is provided as background art to help understand the content disclosed herein. It should be noted that this specification makes neither a claim nor a judgment as to whether any of the above content can be considered prior art related to the content disclosed herein. Summary of the Invention

[0006] The problem the invention aims to solve Traditional massage devices primarily focus on relieving physical fatigue through mechanical stimulation. However, due to the fixed intensity and pattern of stimulation, they are difficult to respond precisely to the user's physical condition or the characteristics of different body parts. This limitation is particularly pronounced for areas requiring meticulous care, such as the face and scalp.

[0007] In particular, the face and scalp, as areas that not only play a vital role in maintaining healthy skin and hair follicles but also significantly influence overall relaxation and stress relief, are increasingly requiring specialized care techniques for these areas. However, existing massage devices do not offer additional care functions tailored to these areas, and even when they do, they are limited to physical stimulation with relatively limited effectiveness.

[0008] Therefore, the present invention aims to provide an upgraded massage device that overcomes the limitations of traditional devices that rely on mechanical stimulation by integrating light irradiation technology (e.g., LED, near-infrared) suitable for the face and scalp into the massage device, thereby providing users with customized health management and beauty effects at the same time.

[0009] In addition, another objective of the present invention is to provide a technical means to simultaneously satisfy user convenience and device usability by improving the integrated structural design, control method, user interface, etc. of the light irradiation device.

[0010] The technical problems to be solved by this disclosure are not limited to those described above. From the following description, those skilled in the art will clearly understand some other unmentioned technical problems.

[0067] Figure 1 This is a diagram illustrating a massage device according to an embodiment of the present disclosure.

[0068] A massage device 100 according to an embodiment of the present disclosure may include a massage section that forms an area for accommodating at least a portion of a user's body, supporting the user's body, and massaging a portion of the user's body.

[0069] The massage unit may include at least one of the following massage units: a body massage unit 101 for massaging the user's body; an arm massage unit 102 for massaging the user's arms; and a leg massage unit 103 for massaging the user's legs.

[0070] The body massage unit 101 can massage at least a portion of at least one of the user's upper body and lower body. Specifically, the body massage unit 101 may include: a frame unit 110, which constitutes the skeleton of the body massage unit 101 and supports the user's body; a user input unit 140, for receiving input of any form from the user; and an audio output module 150, for providing audio output of any form to the user. Additionally, although described later, the body massage unit 101 may include: a massage module (e.g., Figure 2 (170), providing massage function to at least a part of the user's body; sensor unit (e.g.: Figure 2 (e.g., 180°), sensing the position of the user's body to prevent the user's body from being trapped, etc. The structures included in the body massage unit 101 described above are merely exemplary embodiments, and the body massage unit 101 may include various other structures in addition to the structures described above.

[0071] In addition, such as Figure 1 The shape and structure of the massage device 100 shown are merely examples. Various forms of massage devices 100 should also fall within the scope of this disclosure without departing from the scope defined by the claims of this disclosure.

[0072] The body massage unit 101 can be formed into a space of any shape to accommodate the user. The body massage unit 101 can have a space that corresponds to the shape of the user's body. For example, as... Figure 1 As shown, the body massage unit 101 can be implemented in a seated configuration that can accommodate the entire body or part of the user's body, thereby supporting at least a portion of the user's body. For example, the body massage unit 101 may include: a backrest part for supporting at least a portion of the user's upper body; and a seat part for supporting at least a portion of the user's lower body.

[0073] The portion of the body massage unit 101 that contacts the ground may include any material or component for increasing friction (e.g., an anti-slip mat, etc.) and may include wheels for enhancing the mobility of the massage device 100.

[0074] At least a portion of the body massage unit 101 is slidable. For example, when the body massage unit 101 begins to massage (or when the body massage unit 101 is actuated), the body massage unit 101 can operate in a form that slides forward while tilting backward. As a result, the body massage unit 101 can provide massage in a backward tilted state.

For example, the massage device 100 may include an actuator for tilting the massage device 100 (or body massage unit 101) backward. The massage device 100 can tilt or return the body massage unit 101 to its original state by actuating the aforementioned actuator. At this time, the actuator may be configured on the seat side of the massage device 100 (e.g., at the seat side). Figure 4 (The base frame 112 of the frame portion 110, which will be described later).

[0075] The massage device 100 may include airbags (not shown). According to one embodiment, the massage device 100 may include multiple airbags.

[0076] Multiple airbags may be located in at least a portion of the body massage unit 101 (e.g., at least one of the following areas in the entire body massage unit 101: the area corresponding to the user's back, the area corresponding to the user's shoulders, the area corresponding to the waist, the area corresponding to the pelvis (or hips), the area corresponding to the thighs, the area corresponding to the pelvis, and the area corresponding to the perineum), at least a portion of the arm massage unit 102, and at least a portion of the leg massage unit 103, but are not limited thereto, and may be disposed in multiple portions of the massage device 100. According to one embodiment, the airbags may also be referred to as "air bags".

[0077] The massage device 100 may include an air supply unit that supplies air to an airbag to inflate it. The air supply unit may be located inside the body massage unit 101 or in the leg massage unit 103. Alternatively, the air supply unit may be located in the arm massage unit 102. Alternatively, the air supply unit may be located outside the massage device 100.

[0078] The frame portion 110 can constitute the skeleton of the internal structure of the body massage portion 101. In terms of defining the overall shape of the massage device 100, the frame portion 110 can be referred to as the "main frame". The frame portion 110 can be made of metal or plastic materials, etc. For example, the frame portion 110 can be made of iron, alloy, steel, etc., but is not limited to these, and can also be made of various hard materials.

[0079] The massage device 100 may include a massage module 170.

[0080] The massage module 170 can be disposed inside the body massage unit 101 to provide any form of mechanical stimulation to a user accommodated in the body massage unit 101. The massage module 170 may include at least one actuator. The massage module 170 can move along a frame portion 110 disposed inside the body massage unit 101. The frame portion 110 includes a main frame (hereinafter... Figure 4 The main framework 111 (to be described later) and the base framework supporting the main framework 111 (hereinafter referred to as...) Figure 4 The massage module 170 (which will be described later as the base frame 112) can move along the main frame 111 of the frame portion 110. In other words, the massage module 170 can massage at least a part of the user's body (or provide massage to at least a part of the user's body) while moving along the frame portion 110.

[0081] A rack gear (hereinafter referred to as a rack) may be provided in the frame portion 110 of the body massage section 101. Figure 4 The rack 111a (described later) of the frame portion 110 can provide mechanical stimulation to various parts of the user's body while moving along the rack. In other words, the rack 111a of the frame portion 110 can be a movement path for the massage module 170 to move. For example, the massage module 170 can provide the user with various massages such as patting or kneading at least one body part among the user's back, shoulders, waist, buttocks, thighs, and pelvis. The massage module 170 may include, but is not limited to, at least one massage unit among ball massage units and roller massage units. According to one embodiment, the massage module 170 may be referred to as the "main massage module".

[0082] The arm massage unit 102 can be disposed on at least one side and the other side of the body massage unit 101. For example, the arm massage unit 102 may include at least one of the following arm massage units: a first arm massage unit disposed on one side of the body massage unit 101 for massaging one side of the user's arm; and a second arm massage unit disposed on the other side of the body massage unit 101 for massaging the other side of the user's arm. The first arm massage unit and the second arm massage unit can be based on the control unit of the massage device 100 (e.g., [missing information]). Figure 2The control of 120) enables the execution of at least one of the following actions: independent actions, relative actions, linked actions, and quasi-linked actions.

[0083] In this disclosure, "quasi-linked action" means that at least one part of the constituent elements performs an independent or relative action with respect to other constituent elements, while another part of the constituent elements performs an action in conjunction with other constituent elements.

[0084] The arm massage unit 102 can provide an arm rest 1021. The user's arm can be accommodated in the arm rest 1021.

[0085] The arm massage unit 102 may be equipped with multiple airbags. According to one embodiment, the arm massage unit 102 can apply pressure to the user's arm using the airbags to provide an arm massage. With the user's arm resting on the arm rest portion 1021, the position of the user's arm can be stably fixed by the expansion of the airbags configured in the arm massage unit 102. The multiple airbags configured in the arm massage unit 102 are selectively expanded or contracted under the control of the control unit 120, thereby applying pressure from the outside in to the user's arm. The pressure action of the multiple airbags configured in the arm massage unit 102 can be performed periodically or non-periodically, and can be driven in at least one synchronous or asynchronous manner.

[0086] In this disclosure, "periodic" can refer to the regularity of the action of at least one component, while "non-periodic" can refer to the irregularity of the action of at least one component. Furthermore, in this disclosure, "synchronous drive" can refer to the simultaneous execution of the action of at least one component with the action of at least one other component, while "asynchronous drive" can refer to the parallel execution of the action of at least one component with the action of at least one other component, with a time difference between them. For example, the compression action of multiple airbags disposed in the arm massage unit 102 can be performed periodically or non-periodically, and such periodic or non-periodic action can be performed simultaneously among the multiple airbags or with a time difference between them.

[0087] Although not shown in the accompanying drawings, in addition to the massage module 170 disposed in the body massage unit 101, the massage device 100 may also include at least one of an arm massage module disposed in the arm massage unit 102 and a leg massage module disposed in the leg massage unit 103.

[0088] The arm massage unit 102 may be provided with an arm massage module including at least one massage unit selected from ball massage unit and roller massage unit. According to one embodiment, when the user rests his arm on the arm resting part 1021, the arm massage module is additionally or alternatively driven to provide arm massage based on the inflation of the airbag.

[0089] The leg massage unit 103 may be disposed at the lower part of the body massage unit 101 and / or at the lower front part of the massage device 100. The leg massage unit 103 may include at least one of the following leg massage units: a first leg massage unit disposed on one side of the body massage unit 101 for massaging one leg of the user; and a second leg massage unit disposed on the other side of the leg massage unit 103 for massaging the other leg of the user.

[0090] The leg massage unit 103 includes a receiving space for accommodating the user's legs and can provide leg massage to the user by massaging at least a portion of the user's legs. For example, the leg massage unit 103 may include a calf massage unit for massaging the user's lower legs and / or a foot massage unit for massaging the user's feet.

[0091] The leg massage unit 103 can adjust its length according to the user's body characteristics. More precisely, the length of the leg massage unit 103 can be adjusted by lengthening or shortening the distance between one end of the leg massage unit 103. For example, when a tall user uses the massage device 100, the length of the leg massage unit 103 needs to be extended because the lower leg is longer. Conversely, when a short user uses the massage device 100, the length of the leg massage unit 103 needs to be shortened because the lower leg is shorter. Thus, the leg massage unit 103 can provide a leg massage customized to the user's height.

[0092] The leg massage unit 103 may include a leg rest 1031 that provides the aforementioned accommodating space. The leg massage unit 103 may include first and second leg massage units corresponding to the user's legs. The leg rest 1031 may include first and second leg rests 1031 to accommodate the user's legs. Corresponding to the aforementioned first and second leg massage units (or first and second leg rests 1031), it is natural that the structure providing the aforementioned accommodating space for each leg massage unit may also include a calf massage unit and / or a foot massage unit. In the following description, the term "lengthening" of the leg massage unit 103 may refer to the lengthening of the leg rest 1031, and "shortening" of the leg massage unit 103 may refer to the shortening of the leg rest 1031.

[0093] The leg massage unit 103 may be equipped with multiple airbags. According to one embodiment, the leg massage unit 103 can apply pressure to the user's leg using the airbags to provide a leg massage. When the user rests their leg on the leg rest portion 1031, the position of the user's leg can be stably fixed by the expansion of the airbags configured on the leg massage unit 103. The multiple airbags configured on the leg massage unit 103 are selectively expanded or contracted under the control of the control unit 120, thereby applying pressure from the outside in to the user's leg. The pressure action of the multiple airbags configured on the leg massage unit 103 can be performed periodically or non-periodically, and can be driven in at least one synchronous or asynchronous manner.

[0094] The leg massage unit 103 may also be provided with a leg massage module including at least one massage unit selected from ball massage unit and roller massage unit. According to one embodiment, when the user rests his / her legs on the leg rest unit 1031, the leg massage module is additionally or alternatively driven to provide leg massage based on the inflation of the airbag.

[0098] The massage device 100 may include an audio output module 150. The audio output module 150 may be located in various positions. For example, the audio output module 150 may include, but is not limited to, multiple output units such as an upper audio output unit disposed at the upper end of the seat area 104 that contacts the user sitting on the massage device 100, a front audio output unit attached to the front end of the arm massage section 102 on the left / right side of the seat area 104, and / or a rear audio output unit attached to the rear end of the arm massage section 102.

[0099] In this case, the audio output module 150 can provide stereo sound such as 5.1 channels, but is not limited to this.

[0100] According to one embodiment of this disclosure, a user can control a massage device 100 using a massage device control device 200. The massage device control device 200 can be connected to the massage device 100 via wired and / or wireless communication.

[0101] The massage device control device 200 can list various modes of medical massage related to body improvement. For example, the medical massage modes included in the list may include at least one of the following: concentration mode, meditation mode, recovery mode, stretching mode, sleep mode, vitality mode, golf mode, hip shaping mode, exam mode, weightlessness mode, and growth mode.

[0102] The massage device control device 200 may include, but is not limited to, at least one of a remote controller, a cellular phone, and a personal digital assistant (PDA), and may include various electronic devices that can be connected to the massage device 100 via wired or wireless communication.

[0103] The massage device 100 may also include a light irradiator 400. When the massage device 100 provides various mechanical (or physical) stimulation to the user using at least one of the leg massage unit 101, arm massage unit 102 and leg massage unit 103, the light irradiator 400 is used additionally or alternatively to provide optical stimulation, thereby performing skin care on the user.

[0104] The massage device 100 can care for the user's skin through a light care mode. In this disclosure, a "light care mode" can refer to a mode in which mechanical stimulation is provided using at least one of the massage parts 101, 102, and 103, while optical stimulation is provided simultaneously using a light irradiator 400. The control unit 120 can execute the light care mode by controlling the massage device 100. In other words, the mechanical massage action using at least one of the massage parts 101, 102, and 103 of the massage device 100 and the light irradiation action using the light irradiator 400 can be controlled by the control unit 120. The control unit 120 can independently, relatively, jointly, or quasi-jointly control various mechanical massage actions and light irradiation actions based on the massage program (massage mapping) corresponding to the light care mode stored in the storage unit 130, thereby providing the user with various light care modes.

[0105] The skin care actions using the light irradiator 400 of the massage device 100 can be controlled by the control unit 120 to perform in accordance with various mechanical massage actions based on a pre-stored massage program (massage mapping). In terms of light irradiation of the user's skin, the light care mode can also be referred to as a "skin care mode," "skin light care mode," or "skin light therapy mode," etc. Alternatively, it can be simply referred to as "light care," "light therapy," etc. However, the various light care modes disclosed herein are not limited to the embodiments described above. Since this disclosure primarily focuses on the light care mode utilizing the light irradiator 400, the mode in which the control unit 120 controls the massage device 100 without using the light irradiator 400 (e.g., controlling it in a single mode that only provides massage) can be described as a "non-light care mode." As will be explained in detail later, the non-light care mode can also be referred to as "third mode M3" or "unspecified mode," etc.

[0106] According to the massage device 100 of this disclosure, while the massage module 170 promotes blood flow to the body parts, the light irradiator 400 irradiates specific wavelengths of light that can activate skin cells or provide a penetrating effect into the dermis. The massage device 100 of this disclosure, through the combined effect of mechanical stimulation from this mechanical massage action and optical stimulation from the light irradiation action, can provide superior therapeutic and cosmetic effects compared to using mechanical stimulation or optical stimulation alone. The control unit 120, by controlling the massage device 100, applies light stimulation to the user's skin in a state where the skin tissue is relaxed due to mechanical stimulation, blood flow is promoted, and metabolism is activated, thereby increasing the light absorption rate and ultimately providing superior therapeutic and cosmetic effects compared to a single mode that only provides massage.

[0107] According to one embodiment, the massage device 100 may include multiple different light care modes as light care modes. For example, the light care modes may include a first care mode and a second care mode. According to one embodiment, the first care mode and the second care mode can be distinguished based on the location of the body part irradiated by the light irradiator 400. Thus, at the level of performing care on a first body part of the user, the first care mode may be referred to as the "first body part care mode," and at the level of performing care on a second body part of the user that is different from the first body part, the second care mode may be referred to as the "second body part care mode." For example, the first body part may be the user's face, and the second body part may be the user's scalp, but it is not limited to these.

[0108] According to one embodiment, the light irradiator 400 may be detachably mounted on a mounting portion 105 disposed on the massage device 100. For example, the mounting portion 105 may be formed on the upper end of the massage device 100 corresponding to the user's head, so that the light irradiator 400 may be configured to perform care on the upper body area of ​​the user's body, including at least one of the scalp and face.

For example, the massage device 100 can be controlled by controlling the movement of the massage module 170 and / or the airbags included in it.

[0113] The control unit 120 can be implemented by one or more processors. When the control unit 120 is implemented by multiple processors, at least some of the processors can be located at a physically separated distance from each other. However, the control unit 120 is not limited to this and can be implemented in various ways.

[0114] For example, the control unit 120 may include one or more processors. The processor may be implemented by an array of multiple logic gates, or by a combination of a general-purpose microprocessor and a memory storing a program executable in the microprocessor. Furthermore, as will be understood by those skilled in the art to which this embodiment pertains, it may also be implemented in other forms of hardware. For example, the control unit 120 may be implemented using at least one of application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic units for performing functions.

[0115] The control unit 120 can control the operation of the massage device 100 by controlling multiple actuators.

[0116] For example, the massage device 100 may include at least one of the following: a motion actuator for moving the massage module 170 along the frame portion 110; at least one actuator disposed in the massage module 170; a back angle actuator; an actuator for moving the armrest frame support; a leg angle actuator; a foot massage actuator; a leg length adjustment actuator; and a sliding actuator. The control unit 120 can control the operation of the massage device 100 by controlling at least one of these structures.

[0117] The motion actuator of the massage module 170 can be an actuator capable of moving the massage module 170 itself in at least one of the vertical and horizontal directions and the front-back direction. By means of the motion actuator of the massage module, the massage module 170 can move along the rack 111a of the frame portion 110.

[0118] The massage module 170 may also include at least one actuator, and the control unit 120 can control various massage actions by actuating the at least one actuator. For example, the control unit 120 can provide rolling massage, tapping massage, kneading massage, etc., but is not limited to these, by actuating the at least one actuator included in the massage module 170. The at least one actuator included in the massage module can be various actuators such as up-and-down movement actuators, back-and-forth movement actuators, and massage actuators. Up-and-down movement actuators can cause the massage units in the massage module 170 to rise or fall in at least one of the upward and downward directions. Back-and-forth movement actuators can cause the massage module 170 to move forward or backward (or tilt) in at least one of the forward and backward directions of the massage module. The massage actuators can provide various massage actions to the user by causing the massage module 170 to perform various movements. Massage actuators may include, for example, kneading actuators and tapping actuators.

[0119] The back angle actuator is an actuator that adjusts the angle of the part of the massage device 100 that contacts the user's back. The back angle of the massage device 100 can be adjusted by the movement of the back angle actuator.

[0120] The actuator that moves the armrest frame support is an actuator that adjusts the position of the armrest rest in the massage device 100 for resting the user's arm. The position of the armrest rest can be adjusted by using the actuator that moves the armrest frame support, that is, the position of the arm massage unit 102 and / or the massage components of the arm massage unit 102 (arm massage unit airbag, ball massage unit and / or roller massage unit, etc.) can be adjusted.

[0121] The leg angle actuator is an actuator that adjusts the angle of the leg massage section 103 of the massage device 100. The angle between the leg massage section 103 and the body massage section 101 can be adjusted by the movement of the leg angle actuator. For example, the angle of the leg massage section 103 can be the angle between the seat section (or seat area) of the body massage section 101 and the leg massage section 103. The angle of the first leg massage section can be the angle between the seat section and the first leg massage section, and the angle of the second leg massage section can be the angle between the seat section and the second leg massage section.

[0122] As described above, the angle of the leg massage unit 103 is the angle between the seat and the leg massage unit 103, but it is not limited to this. For example, the angle of the leg massage unit 103 can be the angle between the mounting surface (or support surface, ground) of the massage device 100 and the leg massage unit 103.

[0123] In the following text, the angle of the leg massage unit 103 is assumed to be the angle between the leg massage unit 103 and the body massage unit 101.

[0124] A foot massage actuator is an actuator that actuates the foot massage module included in the leg massage unit 103. For example, the control unit 120 can provide foot massage to the user by using the foot massage actuator.

[0125] The leg length adjustment actuator is an actuator that adjusts the length of the leg massage unit 103. For example, the control unit 120 can use the leg length adjustment actuator to adjust the length of the leg massage unit 103 to fit the user, so that the user can receive a massage that matches their body shape. For example, the leg length adjustment actuator can adjust the length of each leg massage unit respectively disposed in the first and second leg massage units. At this time, the leg length adjustment actuator can lengthen or shorten the length of each leg massage unit by adjusting the length between one end and the other end of each leg massage unit.

[0126] The sliding actuator enables the massage device 100 to slide. For example, by utilizing the action of the sliding actuator, the upper frame of the base (e.g., which will be described below) Figure 4 The upper base frame 112a) can move forward or backward, and as a result, the main frame 111 connected to the upper base frame 112a can also move forward or backward.

[0127] In addition, this disclosure may include Figure 1 The airbag and / or air supply unit described herein are considered as structures included in the massage module 170.

[0163] The rack 111a can be made of metal or plastic. For example, the rack 111a can be made of iron, steel, alloy, reinforced plastic, melamine resin, phenolic resin, etc., but is not limited to these.

[0164] In this disclosure, although rack 111a is disclosed as a component for guiding the movement of massage module 170, according to embodiments, massage device 100 may additionally or alternatively provide a component for guiding the movement of massage module 170, i.e., a track structure, based on rack 111a.

[0165] According to an embodiment of the present disclosure, a massage module 170 may include a base plate 171, a massage unit 172, a drive unit 173, and a drive wheel 174.

[0166] The base plate 171 may be a component used to support the massage unit 172, drive unit 173, and drive wheel 174 included in the massage module 170. The base plate 171 can move along the main frame 111 together with the drive wheel 174 according to the movement of the drive unit 173.

[0167] According to one embodiment, an opening may be formed on the base plate 171 that extends through the massage module 170 in the front / back direction (e.g., the X-axis direction). Through the opening, the massage unit 172 can move in the front / back direction (e.g., the X-axis direction) under the action of the drive unit 173.

[0168] According to one embodiment, the drive wheel 174 may be guided by a rack 111a (or track structure) of the main frame 111 to be able to move along the up / down direction (e.g., the Z-axis direction) of the massage device 100. The drive wheel 174 may include a guide roller 1741 and a guide gear 1742, which may mesh with and rotate with the rack 111a (or track structure).

[0169] According to one embodiment, the drive unit 173 may include at least one actuator. By rotating the gear connected to the massage unit 172 through the at least one actuator disposed in the drive unit 173, the massage module 170 can be moved.

[0170] The massage unit 172 may consist of a pair of massage units 1721 and 1722. According to one embodiment, the pair of massage units 1721 and 1722 may be symmetrical about the drive unit 173.

[0171] A pair of massage units 1721, 1722 may each include a ball massage unit and / or a roller massage unit configured to directly contact the user's body to perform a massage. Figure 4 The example shown is a roller massage unit, but it is not limited to this.

[0172] A pair of massage units 1721, 1722 may each include at least one contact roller (or contact ball) that contacts the body to perform a massage. For example, Figure 4 In one embodiment, a pair of massage units 1721 and 1722 are shown, each comprising a first contact roller 1721a, 1722a and a second contact roller 1721b, 1722b spaced apart from each other. The first contact rollers 1721a, 1722a and the second contact rollers 1721b, 1722b can be connected to connecting frames 1721c, 1722c, respectively. The connecting frames 1721c, 1722c have arm-like shapes extending in different directions from each other, and the first contact rollers 1721a, 1722a and the second contact rollers 1721b, 1722b can be positioned at predetermined distances in the up / down direction of the massage device 100.

[0173] The massage module 170 can be moved in the up / down direction of the massage device 100 by the driving force provided by the drive unit 173. As described above, when the massage module 170 moves in the up / down direction of the massage device 100, it can also move in the front / back direction of the massage device 100 by means of a rack 111a that at least partially includes a curve.

[0174] The massage unit 172 can move in the up / down direction along with the base plate 171. The up / down movement and the forward / backward movement of the massage unit 172 can be performed independently of each other.

[0175] According to one embodiment, the pair of massage units 1721, 1722 can also move closer to or further away from each other. The width-direction movement of the pair of massage units 1721, 1722 can be performed independently relative to the up / down direction movement and / or the forward / backward direction movement of the massage unit 172.

[0176] The massage module 170 can provide rolling massage by moving up / down in the massage unit 172, tapping massage by moving forward / backward in the massage unit 172, and kneading massage by moving in the width direction.

[0177] Movement of the massage unit 172 in the up / down direction can be performed by an up / down movement actuator included in the drive unit 173. Movement of the massage unit 172 in the front / back direction can be performed by a back / forward movement actuator included in the drive unit 173. According to one embodiment, the drive unit 173 may additionally or alternatively include a tapping actuator in addition to the back / forward movement actuator. The drive unit 173 may include an actuator for moving the massage unit 172 in the width direction. For example, by using an actuator that moves the massage unit 172 in the width direction, a kneading action can be performed, and therefore the actuator may be referred to as a "kneading actuator".

[0178] The more the massage unit 172 of the massage module 170 moves forward, the greater the massage intensity may be. Conversely, the more the massage unit 172 of the massage module 170 moves backward, the less the massage intensity may be. Here, "moving forward" means that the massage unit 172 moves towards the user, and "moving backward" can mean that the massage unit 172 returns to its position before moving towards the user.

[0179] The main frame 111 can be implemented in various shapes. For example, depending on the shape, the main frame 111 can be divided into S-frame, L-frame, S&L-frame, double S&L-frame, but is not limited to these.

[0180] An S-frame refers to a frame in which at least a portion of the main frame 111 includes a shape that is curved like an "S". An L-frame refers to a frame in which at least a portion of the main frame 111 includes a shape that is curved like an "L". An S&L frame refers to a frame that includes both a shape that is curved like an "S" and a shape that is curved like an "L". A double S&L frame refers to a frame that includes a shape that is curved like an "L" and two parts that are curved like an "S".

[0181] The base frame 112 refers to the part of the frame section 110 that supports the main frame 111 and is in contact with the ground. The base frame 112 may include an upper base frame 112a and a lower base frame 112b.

[0182] The upper base frame 112a can support the main body frame 111, and the lower base frame 112b can contact the ground. In addition, the upper base frame 112a can be connected to the lower base frame 112b.

[0183] According to one embodiment of this disclosure, the upper base frame 112a can move along the lower base frame 112b. For example, the upper base frame 112a can slide forward or backward along the lower base frame 112b. In this case, the main body frame 111 is connected to the upper base frame 112a and can move with the movement of the upper base frame 112a.

[0184] For example, when the upper base frame 112a moves forward, the main body frame 111 can also move forward together; when the upper base frame 112a moves backward, the main body frame 111 can also move backward together. Therefore, it is possible to allow the body massage section (e.g.: Figure 1 The sliding of 101).

[0185] Specifically, to enable the upper frame 112a of the base to move, casters can be provided at the lower part of the upper frame 112a. Additionally, a guide member can be provided at the upper part of the lower frame 112b of the base to guide the casters. The casters on the upper frame 112a move along the guide member on the lower frame 112b, thereby allowing the upper frame 112a to move forward or backward.

[0186] According to another embodiment of this disclosure, the massage device 100 may not provide a sliding function, in which case the base frame 112 may not be separated into an upper frame and a lower frame.

[0187] Figure 5 This is a diagram illustrating the movement of a pair of massage units included in a massage module according to an embodiment of the present disclosure in the width direction.

[0188] The massage device 100 can provide the user with massage actions according to different modes through the massage unit 172 included in the massage module 170. The massage actions can be controlled by the control unit 120.

[0189] Reference Figure 5 The massage unit 172 can be configured as a pair of massage units 1721, 1722, which can be moved toward or away from each other by the drive unit 173. Figure 5 The distance between a pair of massage units 1721, 1722 with reference to a pair of first contact rollers 1721a, 1722a can be shown.

[0190] exist Figure 5 The following embodiment is shown: an embodiment in which a pair of first contact rollers 1721a, 1722a are configured relatively close to each other ( Figure 5 In embodiment (a), a pair of first contact rollers 1721a and 1722a are configured relatively far apart. Figure 5(c) of the embodiments, a pair of first contact rollers 1721a, 1722a are configured with a moderate distance from other embodiments. Figure 5 (b) in the middle.

[0191] For example, Figure 5 (a) shows the minimum spacing W1 between a pair of first contact rollers 1721a and 1722a. Figure 5 (b) shows the moderate spacing W2 between a pair of first contact rollers 1721a and 1722a. Figure 5 (c) shows the maximum distance W3 between a pair of first contact rollers 1721a and 1722a.

[0192] Although Figure 5 The illustration shows three different states of the embodiment, but the movement of the massage unit 172 can be further subdivided between the maximum and minimum spacing distances. According to one example, in a massage device (e.g.: Figure 1 refer to Figure 4 In various massage modes of 100), with Figure 5 The states of the same massage unit 172 in the illustrated embodiment can be implemented sequentially or in reverse order and executed repeatedly.

[0193] Figure 5 The illustration shows a kneading massage action performed by the movement of a pair of massage units 1721, 1722 in the width direction. This is merely an example, and the action of the massage unit 172 is not limited to the above embodiment.

[0194] The massage unit 172 can be configured to move in a variety of different ways to provide additional massage actions to the user's body. For example, although not shown, the massage unit 172 is configured to move forward / backward and perform a patting massage on the body.

[0195] For example, the forward / backward movement of the massage unit 172 may include the forward / backward movement of the first contact rollers 1721a, 1722a and / or the second contact rollers 1721b, 1722b. In this case, the first contact rollers 1721a, 1722a and / or the second contact rollers 1721b, 1722b may be configured to move in the forward / backward direction. The forward / backward movement of the massage unit 172 may be differentiated and performed in stages between the maximum forward position and the maximum rearward position of the massage unit (e.g., the first contact rollers 1721a, 1722a and / or the second contact rollers 1721b, 1722b).

[0196] For example, depending on the configuration of the massage unit 172 (e.g., the first contact rollers 1721a, 1722a) and the degree to which it moves from its maximum rear position to its maximum forward position, the protrusion degree of the massage module 170 can be set to multiple stages (e.g., XD (X-direction) stages 0 to 5). For example, stage XD0 may refer to the massage module 170 protruding at its minimum forward (e.g., in the X-axis direction), and stage XD5 may refer to the massage module 170 protruding at its maximum. From stage XD0 to stage XD5, the protrusion degree of the massage module 170 can gradually increase. The protrusion degree of the massage module 170 can be related to the user's posture while seated on the massage device (e.g., ...). Figure 1 to Figure 4 The massage intensity is proportional to the number of stages received by the user (100%). This is just one example and is not limited to the stages described. According to an embodiment, the control unit 120 may also control the operation of the massage unit 172 with fewer or more stages than in the above embodiments.

[0197] According to another embodiment, the forward / backward movement of the massage unit 172 is combined with its movement in the width direction to provide a combination of tapping massage and kneading massage.

[0198] According to another embodiment, for the forward / backward movement and / or movement in the width direction of the massage unit 172, movement in the up / down direction can also be additionally combined.

[0199] The massage device 100 can independently, relatively, quasi-linkedly, or linkedly control at least one of the following massage actions through the massage unit 172: rolling massage in the up / down direction, tapping massage in the front / back direction, and kneading massage in the width direction, by means of the control unit 120.

[0200] Figure 6 This is a diagram illustrating an airbag according to an embodiment of the present disclosure.

[0201] Reference Figure 6 The massage device 100 may include a plurality of airbags 190. According to one embodiment, the plurality of airbags 190 may include a plurality of auxiliary airbags. The number and configuration of the auxiliary airbags may vary depending on the specific embodiment or the corresponding body part of the user.

[0202] Multiple airbags 190 may be disposed on at least one of the body massage unit 101, arm massage unit 102, and leg massage unit 103. The control unit 120 can activate at least one of the multiple airbags 190. For example, the control unit can inject air into at least one of the multiple airbags 190, causing the airbag to inflate.

[0203] by Figure 6For example, the multiple airbags 190 may include a shoulder airbag 191, a back airbag 192, an arm airbag 193, a thigh airbag 194, a pelvic airbag 195, a perineal airbag 196, a calf airbag 197, an ankle airbag 198, and an instep airbag 199, but are not limited to this and may be applied to other various embodiments. According to one embodiment, the multiple airbags 190 may include a pair of airbags arranged at corresponding positions on the left and right sides, based on a virtual line (not shown) through the massage device 100. For example, the shoulder airbag 191, back airbag 192, arm airbag 193, thigh airbag 194, pelvic airbag 195, calf airbag 197, ankle airbag 198, and instep airbag 199 may each include a pair of airbags.

[0204] The shoulder airbag 191 may include a first shoulder airbag 191a and a second shoulder airbag 191b. For example, the first shoulder airbag 191a may be configured to be disposed at least at one of the front and side of the user's left shoulder to provide pressure on the left shoulder, and the second shoulder airbag 191b may be configured to be disposed at least at one of the front and side of the user's right shoulder to provide pressure on the right shoulder.

[0205] The back airbag 192 may include a first back airbag 192a and a second back airbag 192b. For example, the first back airbag 192a may be configured to be disposed at least at one of the user's left back rear and side to provide pressure on the left back, and the second back airbag 192b may be configured to be disposed at least at one of the user's right back rear and side to provide pressure on the right back.

[0206] The arm airbag 193 may include a first arm airbag 193a and a second arm airbag 193b. For example, the first arm airbag 193a may be configured to be disposed at least at one of the above, below and side of the user's left arm to provide pressure on the left arm, and the second arm airbag 193b may be configured to be disposed at least at one of the above, below and side of the user's right arm to provide pressure on the right arm.

[0207] The thigh airbag 194 may include a first thigh airbag 194a and a second thigh airbag 194b. For example, the first thigh airbag 194a may be configured to be disposed at least at one of the rear and side of the user's left thigh to provide pressure on the left thigh, and the second thigh airbag 194b may be configured to be disposed at least at one of the rear and side of the user's right thigh to provide pressure on the right thigh.

[0208] The pelvic airbag 195 may include a first pelvic airbag 195a and a second pelvic airbag 195b. For example, the first pelvic airbag 195a may be configured to be disposed at least at one of the posterior and lateral portions of the user's left pelvis to provide pressure on the left pelvis, and the second pelvic airbag 195b may be configured to be disposed at least at one of the posterior and lateral portions of the user's right pelvis to provide pressure on the right pelvis.

[0209] The calf airbag 197 may include a first calf airbag 197a and a second calf airbag 197b. For example, the first calf airbag 197a may be configured to be disposed at least at one of the rear, left, and right sides of the user's left calf to provide pressure on the left calf, and the second calf airbag 197b may be configured to be disposed at least at one of the rear, left, and right sides of the user's right calf to provide pressure on the right calf.

[0210] The ankle airbag 198 may include a first ankle airbag 198a and a second ankle airbag 198b. For example, the first ankle airbag 198a may be configured to be disposed at least at one of the rear, left, and right sides of the user's left ankle to provide pressure on the left ankle, and the second ankle airbag 198b may be configured to be disposed at least at one of the rear, left, and right sides of the user's right ankle to provide pressure on the right ankle.

[0211] The instep airbag 199 may include a first instep airbag 199a and a second instep airbag 199b. For example, the first instep airbag 199a may be configured to be disposed at least at one of the front, left, and right sides of the user's left instep to provide pressure on the left instep, and the second instep airbag 199b may be configured to be disposed at least at one of the front, left, and right sides of the user's right instep to provide pressure on the right instep.

[0212] A part of the user's body may be compressed and moved due to the inflation of the airbag at the corresponding location, or it may be clamped and fixed in position.

[0213] For example, when the first shoulder airbag 191a is inflated by air and the second shoulder airbag 191b is deflated, the left shoulder of the user's upper body will be fixed in position due to the pressure exerted by the inflated first shoulder airbag 191a on the front and side of the left shoulder, while the right shoulder of the user's upper body can move freely. When air is injected into the first calf airbag 197a (or the second calf airbag 197b), the user's left (or right) leg may be clamped by the first calf airbag 197a (or the second calf airbag 197b) and its movement restricted. According to another embodiment, when both the first calf airbag 197a and the second calf airbag 197b are inflated by air, the user's legs are clamped by the calf airbag 197a and their movement restricted.

[0214] For example, when it is necessary to adjust the length of the leg massage unit 103 according to the user's body shape, the control unit 120 can adjust the length of the leg massage unit 103 while injecting air into the first calf airbag 197a and the second calf airbag 197b to fix the leg.

[0215] As another example, when the first back airbag 192a is inflated and filled with air, the left side of the user's upper body may move forward toward the left back due to the pressure exerted on the left back by the inflated first back airbag 192a.

[0216] According to one embodiment, after the control unit 120 performs an air injection operation on at least one of the plurality of airbags 190, the control unit 120 can control a portion of the plurality of airbags 190 to perform an air deflation operation after a preset time or based on a preset massage mode. Deflating the airbags can refer to expelling air from the inflated airbags, causing the airbags to contract.

[0217] As described above, the control unit 120 can control the contraction and expansion of multiple airbags 190 disposed at different positions on the massage device 100 according to different light care modes, thereby controlling the mechanical massage action of the massage device corresponding to the light irradiation action of the light irradiator 400.

[0218] Figure 7 This is a perspective view of the back of a light irradiator according to an embodiment of the present disclosure. Figure 8 This is a perspective view of the bottom surface of a light irradiator according to an embodiment of the present disclosure. Figure 9 This is a perspective view showing the state of a light irradiator after sliding, according to an embodiment of the present disclosure.

[0219] The massage device 100 may include a light irradiator 400 configured in a movable manner.

[0220] Reference Figure 1 ,Figure 7 and Figure 8 The light irradiator 400 can be disposed on one side of the body massage unit 101. For example, the light irradiator 400 can be disposed on the upper part (or the upper back) of the body massage unit 101.

[0221] The control unit 120 can control the light irradiator 400 to irradiate light onto at least one of the user's first body part (e.g., face) and second body part (e.g., scalp) to care for (or treat) the user's body part. At this time, the light irradiator 400 can slide relative to the body massage unit 101 in at least one direction, either forward or backward. When moving forward, it can irradiate light onto the first body part, and when moving backward, it can irradiate light onto the second body part.

[0222] With the sliding structure of the light irradiator 400, users can receive continuous care for different body parts (e.g., first body part and second body part) from the same device, thus receiving effective and consistent light therapy without the need for additional device replacement.

[0223] Reference Figure 1 , Figure 7 and Figure 8 According to an embodiment of the present disclosure, a light irradiator 400 may include a fixing portion 410, a sliding portion 420, and an optical module 430. For example, the light irradiator 400 may include: a fixing portion 410 for fixing a position to one end of a body massage portion 101; a sliding portion 420 for sliding on the fixing portion 410; and an optical module 430 disposed on at least a portion of the sliding portion 420 and irradiating light onto a part of the user's body.

[0224] According to one embodiment, the light irradiator 400 can be detachably mounted on the body massage unit 101 as needed. For example, the fixing part 410 of the light irradiator 400 can be detachably mounted on the cover (the outer shell of the body massage unit 101).

[0225] Specifically, the light irradiator 400 may further include a mounting portion 105, which can be detachably connected to the body massage unit 101 via the mounting portion 105 and / or an additional bracket structure configured on the mounting portion 105. By providing the mounting portion 105 and / or the bracket structure for mounting and detaching the light irradiator on the body massage unit 101, the fixing portion 410 can be detachably combined with the mounting portion 105 and / or the bracket structure, and the sliding portion 420 connected to the optical module 430 is movably configured on the fixing portion 410.

[0226] Since the light irradiator 400 can be detachably connected via the mounting part 105 of the body massage part 101 and / or the bracket structure for mounting and dismounting the light irradiator, the user can easily replace and maintain the light irradiator 400 (e.g., the optical module 430 of the light irradiator 400).

[0227] According to an embodiment, the mounting portion 105 can be integrated as a component of the body massage unit 101, or it can be integrated as a component of the light irradiator 400. For example, when the mounting portion 105 is integrated as a component of the body massage unit 101, the mounting portion 105 can be integrally formed with the body massage unit 101. According to one embodiment, the mounting portion 105 can serve as a housing covering the upper rear of the body massage unit 101, and can be referred to as a "back cover". In this case, the light irradiator 400 can be fastened or separated from the mounting portion 105, which serves as the back cover, through the aforementioned additional support structure, thereby enabling attachment and removal from the body massage unit 101.

[0228] In this disclosure, the light irradiator 400 can provide a user with low-level laser therapy (LLLT) by irradiating a user with light of a specific wavelength onto at least one of a first body part and a second body part, thereby promoting metabolism and activating tissue function in that body part. While the massage device 100 of this disclosure is configured to use the light irradiator 400 to irradiate light in order to provide the aforementioned low-level laser therapy to a user, it is not limited thereto. For example, the light irradiator 400 can employ at least one of low-level laser therapy and high-level laser therapy to irradiate at least one of low-intensity light with lower light intensity and high-intensity light with higher light intensity. For ease of explanation, the use of low-level laser therapy will be assumed below. However, it is reasonable to assume that the content related to low-level laser therapy described below is also applicable to high-level laser therapy.

[0229] By utilizing the light irradiated by the light irradiator 400, the massage device 100 can provide the user with the following effects: improved skin texture, enhanced radiance, moisturization, increased elasticity, improved skin tone, increased firmness, and improved sagging. For the scalp, it can provide the following effects: improved hair thickness, increased elasticity, regulated sebum, reduced hair breakage, and reduced hair tensile strength.

[0230] Reference Figure 9The light irradiator 400 can be configured such that the sliding portion 420 can slide on the fixed portion 410. For this purpose, a sliding track 411 (or sliding groove) can be formed on the fixed portion 410 of the light irradiator 400. The sliding track 411 can be formed to extend along the length direction of the fixed portion 410 in a front / back direction. The user can hold one side of the sliding portion 420 and slide it on the fixed portion 410 in a predetermined direction (specifically, the front / back direction) (e.g., reciprocating sliding).

[0231] Alternatively, the light irradiator 400 may also include an actuator disposed on at least one of the sliding portion 420 and the fixed portion 410. The control unit 120 can drive the actuator disposed on the light irradiator 400 to slide the sliding portion 420 on the fixed portion 410. For example, the actuator for sliding the sliding portion 420 can be disposed on either the sliding portion 420 or the fixed portion 410, connecting the fixed portion 410 and the sliding portion 420. Furthermore, by adjusting the distance between the fixed portion 410 and the sliding portion 420, the sliding portion 420 can be slid forward and / or backward relative to the fixed portion 410. At this time, one end of the actuator that slides the sliding part 420 is connected (or fastened) to at least a portion of the fixed part 410, and the other end of the actuator is connected (or fastened) to at least a portion of the sliding part 420 (more preferably a rear portion of the sliding part 420), so that the sliding part 420 can slide relative to the fixed part 410 by adjusting the length between one end and the other end of the actuator.

[0232] According to one embodiment, a fixed roller portion 415 may be provided on the fixed portion 410. The fixed roller portion 415 may be configured to support the lower part of the sliding portion 420 and enable rolling contact when the sliding portion 420 slides.

[0233] According to one embodiment, the control unit 120 of the massage device 100 can control the sliding of the light irradiator 400 based on a preset light care mode. For example, the control unit 120 can control the position of the sliding part 420 to move to a first position to irradiate light onto a first body part, and control the position of the sliding part 420 to move to a second position different from the first position to irradiate light onto a second body part. The control unit 120 can control the position of the sliding part 420 to obtain the most effective skin care effect for different body parts.

[0234] The following is through Figure 10 to Figure 19 The embodiments are described in detail to utilize according to Figure 1 to Figure 11 The massage device 100 described in the embodiments herein and the massage device 100 and the control method thereof are configured to perform actions including various light care modes.

[0235] Figure 10This is a diagram showing a first state of a massage device according to an embodiment of the present disclosure. Figure 11 This is a diagram showing a second state of the massage device according to an embodiment of the present disclosure.

[0236] Reference Figure 10 and Figure 11 The body massage section 101 of the massage device 100 can be tilted to achieve the first state ( Figure 10 ) and second state ( Figure 11 Among them, the first state ( Figure 10 This can represent the sitting mode of the massage device 100 when the user is seated on it. Second state ( Figure 11 This can indicate that when the user is sitting on the massage device 100, the backrest 1011 is tilted, allowing the massage device 100 to be tilted so that the user can lie down.

[0237] According to one embodiment, the first state ( Figure 10 This can represent the state where the massage device 100 is not tilted backward (0% tilt state), and the second state ( Figure 11 This can represent the state where the massage device 100 is tilted backward to its maximum extent (100% tilt state). For example, in the first state ( Figure 10 In this state, the uppermost end of the massage device 100 (e.g., light irradiator 400) may be located on a virtual line L1 passing through the main hinge axis MA, for example, in the second state. Figure 11 The uppermost end of the massage device 100 (e.g., light irradiator 400) may be located on a virtual line L2 passing through the main hinge axis MA.

[0238] The massage device 100 can be configured in a first state ( Figure 10 ) and second state ( Figure 11 The massage device 100 performs massage and light irradiation actions on the user, respectively. In the massage device 100, the massage and light irradiation actions can be performed independently, relative, in conjunction, or quasi-in conjunction. However, according to an embodiment of this disclosure, the massage device 100 is characterized in that its control unit 120 controls the massage and light irradiation actions to operate in a conjunction or quasi-in conjunction manner.

[0239] According to one embodiment, the massage device 100 can also be in a first state ( Figure 10 ) and the second state ( Figure 11 The massage device 100 can also be configured to maintain its posture in an intermediate state (e.g., a third state) between the body massage section 101 and the first state. Figure 10 ) and the second state ( Figure 11 Intermediate states at specific angles between (e.g., as will be described below) Figure 17The massage device 100 (e.g., light irradiator 400) performs massage actions on the user when the uppermost part of the massage device 100 is located on the virtual line L5.

[0240] According to one embodiment, when the massage device 100 moves from a first state ( Figure 10 Switch to the second state ( Figure 11 ), or from the second state ( Figure 11 Switch to the first state ( Figure 10 When the body massage part 101 is used, at least a portion of it may be configured to slide forward or backward.

[0241] The body massage section 101 of the massage device 100 can form a corresponding tilting structure according to various modes of the massage device. The massage device 100 can control the tilt of the body massage section 101 in accordance with the light care mode of the massage device described later.

[0242] The massage device 100 can also achieve the following states, except for the first state ( Figure 10 ) and second state ( Figure 11 Other states besides the first state (e.g., the fourth state). For example, Figure 10 and Figure 11 Although not shown in the diagram, the leg massage section 103 can also be tilted. When the body massage section 101 of the massage device 100 is in its first state (0% tilt)... Figure 10 Second state (100% tilt) Figure 11 In the first state and the intermediate state between the second state (e.g., the third state), the leg massage unit 103 can be tilted relative to the body massage unit 101. At this time, the tilting action of the leg massage unit 103 can be performed independently, relatively, quasi-linkedly, or linkedly with the tilting action of the body massage unit 101.

[0243] According to one embodiment (described in detail later), the control unit 120 can tilt the leg massage unit 103 to a predetermined angle based on the user-selected light care mode, thereby controlling the posture of the user sitting on the massage device 100 to provide convenience or to provide effects such as improved blood circulation. For example, the control unit 120 can adjust the angle of the leg massage unit 103 to a preset angle corresponding to the selected light care mode. Specifically, the control unit 120 can lift the leg massage unit 103 by actuating the leg angle actuator, so that at least a portion of the leg massage unit 103 is in a position higher than the seat. Thus, the massage device 100, by irradiating light onto the skin through the light irradiator 400 in a state where the user's legs are lifted above the user's buttocks in the light care mode to improve blood circulation throughout the body, can further enhance the skin improvement effect compared to a situation with poor blood circulation.

[0244] According to one embodiment, Figure 10 This can be interpreted as the leg massage unit 103 also being in a non-tilted state (0% tilt state) when the massage device 100 is not tilted backward. For example, in the minimum tilt state (0% tilt state), the end of the leg massage unit 103 may be located on the virtual line L3 passing through the leg hinge axis LA, and in the maximum tilt state (100% tilt state), the end may be located on the virtual line L4 passing through the leg hinge axis LA.

[0245] The leg hinge axis (LA) refers to the axis that rotatably connects the leg massage unit 103 to the body massage unit 101. The leg massage unit 103 can tilt clockwise and / or counterclockwise around this axis to adjust its angle. The leg massage unit 103 can be connected to the body massage unit 101 via the leg hinge axis LA.

[0246] The virtual line L3 can be the state in which the user's legs naturally face downwards from the massage device 100 due to gravity when the user is sitting on the massage device 100. When the leg massage unit 103 is located on the virtual line L3, it can be considered that the leg massage unit 103 is in the minimum tilt state (0% tilt state).

[0247] The virtual line L4 can represent the state in which the user lifts their legs against gravity. The virtual line L4 can refer to the user's knee being at its maximum extension, and can be a line approximately perpendicular to the virtual line L3. It can be said that when the leg massage unit 103 is located on the virtual line L4, it represents the maximum tilt state (100% tilt state) of the leg massage unit 103, but it is not limited to this. As mentioned above, the leg massage unit 103 can also be positioned above the seating surface of the seat, above L4.

[0248] According to one embodiment, when the light therapy mode is running, the control unit 120 can control the body massage unit 101 and the leg massage unit 103 of the massage device 100 so that the user can sit in a comfortable posture on the massage device 100. For example, when the light therapy mode is running, the control unit 120 can control the body massage unit 101 and the leg massage unit 103 so that the massage device 100 is in an initial first state (0% tilt state).

[0249] Although Figure 11The illustration shows the leg massage unit 103 in a minimum tilt state (0% tilt state) with the body massage unit 101 tilted backward (100% tilt state). However, in the embodiment related to the light care mode described later, the angle of the leg massage unit 103 can be adjusted between the minimum leg angle in the minimum tilt state (0% tilt state) and the maximum leg angle in the maximum tilt state (100% tilt state) in conjunction or quasi-in conjunction with the light irradiation action of the light irradiator 400.

[0250] Figure 12 This is a diagram showing the state of a light illuminator before and after sliding, according to an embodiment of the present disclosure.

[0251] Figure 12 It is magnification Figure 11 The diagram in section A1.

[0252] The light irradiator 400 may include: a fixed portion 410; a sliding portion 420 slidably connected to the fixed portion 410; and an optical module 430 disposed on at least a portion of the sliding portion 420. In this case, the optical module 430 may be disposed on at least a portion of the lower surface of the sliding portion 420 to irradiate light onto the lower side of the sliding portion 420. Preferably, the optical module 430 may be disposed on the lower surface of an end portion of the sliding portion 420.

[0253] The optical module 430 can, for example, illuminate light in at least one of the following wavelengths: 420–480 nm, 630–690 nm, and 850–940 nm. Therefore, the optical module 430 may include at least two different types of light sources. For example, the optical module 430 may include a near-infrared (NIR) optical module and a human centric light (HCI) optical module.

[0254] Near-infrared optical modules penetrate deep into the user's skin by irradiating light with wavelengths above 700 nm (e.g., 850-940 nm), allowing the light to reach the dermis layer. Therefore, near-infrared optical modules can provide effects such as improved blood circulation, promoted cell regeneration, pain relief, and recovery.

[0255] The circadian rhythm regulation optical module provides users with light that aligns with their biological rhythms by irradiating them with light of wavelengths in the range of 400 nm to 700 nm (e.g., 420–480 nm, 630–690 nm). For example, the circadian rhythm regulation optical module uses red light to soothe muscles and induce sleep.

[0256] According to one embodiment, the optical module 430 of this disclosure may include a near-infrared optical module and / or a biorhythm regulation optical module. The control unit 120 controls the near-infrared optical module and / or the biorhythm regulation optical module to irradiate various lights in accordance with various modes of the massage device, thereby providing optimal therapeutic and cosmetic effects.

[0257] The light irradiator 400 may be configured to slide on the massage device 100. According to one embodiment, the light irradiator 400 may be configured to slide in accordance with various modes of the massage device 100.

[0258] The position of the sliding part 420 of the light irradiator 400 relative to the fixed part 410 can be changed by a sliding in / sliding out action. (See reference...) Figure 12 The left side shows the position of the sliding part 420 of the light irradiator 400 in a slide-in state relative to the fixed part 410, while the right side shows the position of the sliding part 420 of the light irradiator 400 in a slide-out state relative to the fixed part 410.

[0259] In the sliding-in state, the optical module 430 of the light irradiator 400 is positioned closest to the fixing part 410. The light irradiator 400 can be configured to irradiate light at a position corresponding to a second body part (e.g., the scalp) of the user. At this time, the sliding-in state is the state in which the length of one end and the other end of the light irradiator 400 is at its shortest, which may be the state in which the sliding part 420 has not yet slid out of the fixing part 410.

[0260] The sliding exit state refers to the state in which the optical module 430 of the light irradiator 400 is away from the fixing part 410. The light irradiator 400 can be configured to be positioned at a position corresponding to a first body part (e.g., face) of the user to irradiate light. At this time, the sliding exit state can be a state in which the length of one end and the other end of the light irradiator 400 is longer than that of the sliding entry state and / or the longest state, or a state in which the sliding part 420 slides out of the fixing part 410.

[0261] As described above, the light irradiator 400 can adjust its length according to the position of the sliding part 420 relative to the fixed part 410 to irradiate light onto the first body part and / or the second body part.

[0262] According to one embodiment, such as Figure 12 As shown, the fixing part 410 and / or the sliding part 420 of the light irradiator 400 can be formed in a curved shape. Thus, the sliding part 420 and the optical module 430 can slide along a curved trajectory (or a non-linear trajectory) and be positioned at positions corresponding to the face (first body part) and the scalp (second body part).

[0263] For example, when the light irradiator 400 is in the sliding-out state, the optical module 430 can be positioned at a location corresponding to the user's face, which is the first body part, to irradiate light onto the user's face. When the light irradiator 400 is in the sliding-in state, the optical module 430 can be positioned at a location corresponding to the user's scalp, which is the second body part, to irradiate light onto the user's scalp.

[0264] As mentioned above Figure 1 As described herein, the light care modes include a first care mode (or, first body part care mode M1) that irradiates light onto a first body part and a second care mode (or, second body part care mode M2) that irradiates light onto a second body part. Furthermore, the control method of the massage device disclosed herein may include the step of controlling the light irradiator to irradiate light onto at least one of a first body part and a second body part different from the first body part.

[0265] In the first care mode (e.g., the first body part care mode), the sliding part 420 of the light irradiator 400 can perform the light irradiation action in the slide-out state. In the second care mode (e.g., the second body part care mode), the sliding part 420 of the light irradiator 400 can perform the light irradiation action in the slide-in state. In other words, the first care mode in which the light irradiator 400 is in the slide-out state can be a mode in which the optical module 430 irradiates light at a position corresponding to the user's face. The second care mode in which the light irradiator 400 is in the slide-in state can be a mode in which the optical module 430 irradiates light at a position corresponding to the user's scalp.

[0266] However, this is not the only limitation. If the sliding action of the sliding part 420 of the light irradiator 400 includes at least three distinct phases (e.g., a slide-out state, a slide-in state, and an intermediate state between slide-out and slide-in), and the light is irradiated while the sliding part is fixed in these states, then light irradiation according to the first care mode M1 can be performed in the slide-out state, and light irradiation according to the second care mode M2 ​​can be performed in the intermediate state. As long as the position of the sliding part 420 in the first care mode M1 is in a state of being away from the fixing part 410 (or the mounting part 105) and protruding compared to the position of the sliding part 420 in the second care mode M2, it can be applied to different embodiments.

[0267] In this disclosure, the face and scalp region are used as examples of the first and second body parts, but the scope of this disclosure is not limited thereto. For example, the first body part could also be the user's abdomen, arms, and / or other body parts such as the abdomen.

[0268] However, although this disclosure refers to Figure 1 , Figure 7 to Figure 9 This demonstrates that the movable range of the light illuminator 400 only reaches the user's face; however, it should be noted that this is for illustrative purposes only, and the movable range of the light illuminator 400 disclosed herein is not limited to any particular embodiment. Depending on the circumstances, the light illuminator 400 may also be configured to illuminate all areas of the user's body.

[0269] Figure 1 , Figure 7 to Figure 9 The light illuminator 400 is shown and its sliding form is disclosed. However, if the light illuminator 400 is configured to irradiate different areas of a user's body, it can be applied in any other form (e.g., a straight line, a cable, or a flexible tube that can be extended by a longer connecting member).

[0270] With the aforementioned movable structure of the light irradiator 400, users can receive care corresponding to different modes of the massage device for different body parts (e.g., the first body part and the second body part) using the same device, thus receiving effective and consistent light therapy effects without the need for additional device replacement.

[0271] Figure 13 This is a diagram showing the state of adjusting the angles of the two leg massage units included in a leg massage unit according to an embodiment of the present disclosure.

[0272] Figure 13 It is magnification Figure 11 The diagram in section A2.

[0273] The leg mounting portions 1031a and 1031b (or the first and second leg massage portions) included in the leg massage unit can be driven by the control unit 120 in at least one of the following ways: independent of each other, relative to each other, linked, and quasi-linked. According to one embodiment, the leg mounting portions 1031a and 1031b can be tilted relative to the body massage unit 101 at the same angle or at different angles.

[0274] According to one embodiment, such as Figure 13As shown, the first leg rest 1031a (or the first leg massage part) and the second leg rest 1031b (or the second leg massage part) are controlled by the control unit 120 to perform alternating cyclic actions (e.g., robot cyclic actions) when viewed from the side of the massage device 100. During this cyclic action, not only is a leg angle adjustment action performed to make the angles of the first leg rest 1031a and the second leg rest 1031b cross, but also a length adjustment action is performed independently, relatively, quasi-linked, or linked to adjust the length of at least one of the first leg rest 1031a and the second leg rest 1031b. For example, the cyclical action can be manifested as follows: when the leg length of one leg massage section (e.g., the first leg massage section 1031) increases (e.g., the length of the first leg rest section 1031a increases), the angle of that leg massage section (e.g., the first leg massage section 1031) relative to the body massage section 101 decreases. At the same time, when the leg length of the other leg massage section (e.g., the second leg massage section 1032) decreases (e.g., the length of the second leg rest section 1032a decreases), the angle of that leg massage section (e.g., the second leg massage section 1032) relative to the body massage section 101 increases. Here, "the angle of the first leg massage section decreases" can refer to... Figure 13 Based on this, the first leg massage section is tilted clockwise to adjust its angle. "The angle of the second leg massage section increases" can refer to... Figure 13 Based on this, the second leg massage section is tilted counterclockwise to adjust its angle.

[0275] Figure 14 This is a block diagram illustrating the control actions of a massage device according to an embodiment of the present disclosure.

[0276] Reference Figure 14 The massage device 100 may include a control unit 120, a body massage unit 101, and a light irradiator 400. The massage device 100 may also include a leg massage unit 103. The control unit 120 can control the operation of the body massage unit 101, the leg massage unit 103, and / or the light irradiator 400. In this case, the control unit 120 can control the body massage unit 101, the leg massage unit 103, and / or the light irradiator 400 independently, relatively, quasi-linked, and / or linked to each other. According to one embodiment, the control unit 120 can control the light irradiator 400 to irradiate light onto at least one part of the user's body.

[0277] According to one embodiment, the massage device 100 may include: a control unit 120 for controlling the massage device; a body massage unit 101 for massaging at least a portion of a user's body; and a light irradiator 400 disposed on at least a portion of the body massage unit 101. The control unit 120 may control the light irradiator 400 to irradiate light onto at least one of a first body part and a second body part different from the first body part of the user.

[0278] According to one embodiment, the second body part may be positioned higher on the user's body than the first body part. The first body part may be, for example, the facial region. The second body part may be, for example, the scalp region, but is not limited thereto. Again, while the first and second body parts are exemplified by the face and scalp respectively, these are merely illustrative examples, and the scope of this disclosure is not limited thereto.

[0279] In this disclosure, as an example of a first body part, the facial region may refer to the central region of the user's face, the region from the upper facial region (e.g., forehead) to the lower facial region (e.g., chin), and the neck region surrounding the face. According to yet another example, the facial region in this disclosure may also be a region that includes at least a portion of the user's shoulders.

[0280] In this disclosure, as an example of a second body part, the scalp region can refer to the area above the user's shoulders, excluding the facial region. While the facial region and scalp region are distinguished and described for convenience, this is not a limitation. For example, the control unit 120 may also consider the upper facial region (e.g., the forehead) as included in the scalp region and control the light irradiator 400 to irradiate light onto the scalp region including the upper facial region (e.g., the forehead). Various other embodiments may also be applied.

[0281] For ease of explanation, the first body part will be assumed to be the face, and the second body part will be assumed to be the scalp.

[0282] According to one embodiment, the control unit 120 of the massage device 100 can control the light irradiator 400 based on at least one of a preset light care mode and preset setting options. The light care mode may include a first care mode M1 and a second care mode M2. The setting options may be preset and stored in the memory of the massage device 100 by at least one of different entities such as the manufacturer, distributor, manager, or user of the massage device 100.

[0283] The control unit 120 can control the light irradiator 400 to operate in at least one of a first care mode M1 for irradiating light onto a first body part and a second care mode M2 ​​for irradiating light onto a second body part. For example, the first care mode M1 can be a mode for irradiating light onto the user's facial area (first body part), and the second care mode M2 ​​can be a mode for irradiating light onto the user's scalp area (second body part). Therefore, the first care mode M1 can be referred to as a "facial care mode," and the second care mode M2 ​​can be referred to as a "scalp care mode."

[0284] The control unit 120 can control the massage device 100 to operate in at least one of the first care mode M1 and the second care mode M2 ​​based on user input and / or the position of the light irradiator 400.

[0285] For example, according to one embodiment, a user can utilize Figure 1 The user input unit 140 and / or the massage device control device 200 control the light irradiator 400 of the massage device 100. The user input unit 140 and / or the massage device control device 200 can list various modes of care. For example, the light care modes included in the care list may include a first care mode M1 and a second care mode M2.

[0286] According to one embodiment, the user input unit 140 and / or the massage device control device 200 may have other lists different from the first care mode M1 and the second care mode M2. When other lists are selected, other modes (e.g., the third mode M3) will be run instead of the light care mode.

[0287] When a user selects a light care mode (e.g., selecting a pre-defined user interface (UI) related to the light care mode), the control unit 120 can control the light irradiator 400 according to preset options corresponding to (or matching) the light care mode. When a user selects a mode different from the light care mode (e.g., the third mode M3) (e.g., selecting a pre-defined UI related to other modes), the control unit 120 can control the light irradiator 400 based on preset settings.

[0288] For example, other lists may include medical massage lists. Thus, the modes selected as the third mode M3 may include, but are not limited to, at least one of the following modes: concentration mode, meditation mode, recovery mode, stretching mode, sleep mode, vitality mode, golf mode, buttock lifting mode, test taker mode, weightlessness mode, and generation mode.

[0289] According to one embodiment, the third mode M3 may also be referred to as a "non-light care mode (or non-specific mode)".

[0290] In the above embodiments, to utilize Figure 1 The description is based on the user input unit 140 and / or the massage device control device 200 receiving user input, but it should be noted that, in addition to this, it can also receive input from the user input unit 140 and / or the massage device control device 200. Figure 3 The input is made through the user input section of the various external devices described herein.

[0291] In this disclosure, the control unit 120 can control the light irradiator 400 to irradiate light onto at least one of the user's first and second body parts based on at least one of the first care mode M1 and the second care mode M2.

[0292] For example, the control unit 120 can control the light irradiator 400 to irradiate light of the first wavelength in the first care mode M1, and control the light irradiator 400 to irradiate light of the second wavelength, which is different from the first wavelength, in the second care mode M2.

[0293] Specifically, in the first care mode M1, light of a first wavelength can be irradiated, and light of a first intensity can be irradiated within a preset first time period. When the first body part is the facial area, the light irradiator 400 can irradiate the facial area with light of the first wavelength for purposes such as anti-aging, whitening, or wrinkle reduction, and can also irradiate light of other wavelengths. For example, in the first care mode M1, light in the visible light range, such as light in the 630~690nm range, can be irradiated, and additionally or alternatively, light in the infrared range, such as light in the 850~940nm wavelength range, can also be irradiated. That is, two or more types of light can be irradiated.

[0294] In the second care mode M2, light of a second wavelength can be irradiated, and light of a second intensity can be irradiated for a preset second time period. The second time period can be the same as or different from the first time period. Similarly, the second intensity of light can be the same as or different from the first intensity of light. When the second body part is the scalp area, the light irradiator 400 can also irradiate light of a wavelength that improves the scalp area or has an anti-hair loss effect. For example, the second care mode M2 ​​can irradiate light in the visible light range, such as light from 420 to 480 nm.

[0295] However, this is only an example and can be applied to different embodiments. For example, both the first care mode M1 and the second care mode M2 ​​can irradiate light of the same wavelength, and the control unit 120 can control at least one of the light intensity and irradiation time of the light irradiator 400 in the first care mode M1 to be different from at least one of the light intensity and irradiation time of the light irradiator 400 in the second care mode M2.

[0296] As another example, the control unit 120 may control the light irradiator 400 to irradiate light onto at least one of the first and second body parts, or other body parts different from these body parts, based on a different mode (or a third mode) than the light care mode.

[0297] According to one embodiment, when the massage device 100 operates in a mode different from the light therapy mode (e.g., third mode M3), the control unit 120 can control the light irradiator 400 to irradiate light according to a preset setting option. According to one embodiment, the setting option may include an option for the control unit 120 to turn the light irradiator 400 on / off according to user input. Turning on the light irradiator 400 may mean activating the optical module 430 of the light irradiator 400 to irradiate light. Conversely, turning off the light irradiator 400 may mean not activating the optical module 430 to not irradiate light. The setting value of the setting option may be the same as or different from the setting value corresponding to the light therapy mode selected by the user (e.g., the light irradiation mode including the wavelength, light intensity, and light irradiation time of the light irradiator 400). For example, when the first (or second) light irradiation time in the first therapy mode M1 (or the second therapy mode M2) is 30 minutes, the light irradiation time according to the setting option may be set to 20 minutes. However, it should be noted that this is only an example and is not limited thereto.

[0298] According to one embodiment, when the light care mode is running, the control unit 120 can control the light irradiator 400 based on the light irradiation mode corresponding to the light care mode, so that the light irradiator 400 irradiates light. For example, the control unit 120 can control the light irradiator 400 to irradiate light at the beginning of the light care mode and control the light irradiator 400 to stop irradiating light at the end of the light care mode. However, this is only an example. The control unit 120 can also control the light irradiator 400 to irradiate light after a predetermined time after the light care mode has run, or automatically control the light irradiator 400 to stop (or terminate) irradiating light after a preset time. That is, the control unit can control the light irradiator 400 to irradiate light or stop irradiating light at different time points during the operation of the light care mode.

[0299] In other words, the light irradiation mode can include multiple modes, including at least one of the following modes: First mode, light is irradiated throughout the entire working interval (or the entire working time, the entire running time) of the light care mode from the start to the end of the light care mode; Second mode, light is irradiated when the light care mode starts running, but the light irradiation is turned off before the end of the light care mode; Third mode, light is irradiated after a specified time has elapsed since the start of the light care mode, and the light irradiation is turned off before the end of the light care mode or at the end of the light care mode; Fourth mode, the light on / off is repeated at least once throughout the entire working interval from the start to the end of the light care mode.

[0300] Furthermore, even when light is irradiating during the operation of the light care mode, if the user inputs a command to stop the light irradiator 400, the control unit 120 can control the light irradiator 400 to switch to the off state, thereby stopping the light irradiation operation. Even if light irradiation is not currently in progress, if the user inputs a command to drive the light irradiator 400, the control unit 120 can control the light irradiator 400 to switch to the on state, thereby starting the light irradiation operation.

[0301] According to one embodiment, when the massage device 100 is used in a mode other than the light care mode (e.g., the third mode M3), the light irradiator 400 can be turned on / off according to the user's input. For example, in a mode other than the light care mode (e.g., the third mode M3), the light irradiator 400 may not irradiate light, but when the user inputs a command to drive the light irradiator 400 at any time, the light irradiator 400 can operate to irradiate light. Additionally, when the light irradiator 400 is in a driven state to irradiate light, when a command to stop the light irradiator 400 is input, the light irradiator 400 can stop irradiating light. That is, in a mode other than the light care mode (e.g., the third mode M3), the light irradiator 400 can operate to irradiate light according to the user's input, and can stop (or end) from irradiating light in at least one of the following situations: user input, termination of the massage device 100, and / or end of another mode. However, it is not limited to this; the massage device 100 may also be configured to automatically stop the light irradiator 400 after a predetermined time.

[0302] According to one embodiment, when the massage device 100 operates in light care mode, the control unit 120 can control it by adjusting at least one of the brightness intensity, light type, and irradiation time of the light irradiator 400 during operation of the light care mode. For example, when the purpose is to care for the skin, it is more advantageous to irradiate with light of different intensities than to continuously irradiate with light from the light irradiator 400 at a predetermined intensity. Therefore, the intensity of the light irradiator 400 can be adjusted at least once during operation of the light care mode.

[0303] More specifically, at the start of the light care mode and at any point during its operation, the control unit 120 can control at least one of the following: brightness intensity, light type, and irradiation time of the light irradiator 400. For example, when the goal is to improve skin elasticity, it is more advantageous to alternate between near-infrared (NIR) light and visible light (e.g., red light) in terms of time. That is, the control unit 120 can control the type of light irradiated by the light irradiator 400 to switch from one wavelength to another during the light care mode. As described above, by changing the type of light, different effects can be provided to the skin surface and the dermis. In addition, to reduce skin irritation or provide user comfort, the control unit 120 can also control the irradiation time. For example, the light can be set to irradiate in pulses at a predetermined cycle (e.g., irradiation for one second followed by a 0.5-second rest) instead of continuously, or the irradiation time can be gradually increased or decreased as the light care mode progresses. This method can eliminate skin fatigue and improve the user's physical experience.

[0304] Furthermore, when operating in other modes besides the light care mode (e.g., mode 3 M3), the light irradiator 400 can irradiate light according to setting options. For example, the control unit 120 can control the operation of the light irradiator 400 based on the setting options. The setting options may include at least one of the following: whether to irradiate light through the light irradiator 400 when operating other modes (e.g., mode 3 M3) (in other words, whether to drive the light irradiator 400), and the light irradiation mode. At this time, as described above, the light irradiation mode may include at least one of the following for controlling the light irradiator 400: the timing of light turning on and / or off, light intensity, light type, and light irradiation time.

[0305] The light irradiator 400 can be configured (or controlled) to irradiate light with at least one of the light intensity, type, and irradiation time altered or unchanged based on the settings corresponding to the light care mode (e.g., light irradiation mode) when operating a light care mode, and to irradiate light with at least one of the settings altered or unchanged based on preset settings when operating a third mode.

[0306] For example, the light irradiator 400 may be configured to irradiate light with a specified brightness intensity, a specified light type, and a specified light irradiation time without changing the light intensity, light type, and light irradiation time, or to irradiate light with a change in at least one of the light intensity, light type, and light irradiation time.

[0307] Specifically, the light irradiator 400 can be configured (or constructed, controlled) to maintain a constant intensity of the irradiated light. According to other embodiments, it can also be configured to irradiate at different intensities for different time periods. In this case, the light irradiator 400 can also be configured to gradually increase or decrease its light intensity in stages, or to change periodically. The type of light irradiated from the light irradiator 400 can be configured to irradiate the same type of light with a single wavelength. According to other embodiments, it can also be configured to irradiate a composite light with multiple wavelengths simultaneously. Additionally, it can be configured to irradiate a first light within a specific time period, followed by irradiating a second light, etc., with different wavelengths of light irradiating more than once in a sequential alternation manner. The light irradiation time of the light irradiator 400 can be configured to be continuously maintained throughout the entire period from the start to the end of the massage action. According to other embodiments, it can also be configured to irradiate only within a certain interval of the entire operating time of the massage device 101. Furthermore, the irradiation time of the light irradiator 400 can also be configured to be subdivided in a pulse pattern, or to irradiate light or stop irradiation at predetermined time intervals. In addition, the light illuminator 400 can also be configured to combine and perform illumination in a specific order and mode according to a user-customized program.

[0308] When operating other modes besides light therapy modes (e.g., mode 3 M3), the control unit 120 can independently control the irradiator 400 to perform light irradiation, independent of the operation of the massage unit (or at least one of the body massage unit 101, arm massage unit 102, and leg massage unit 103). In other words, the control unit 120 can independently control the light irradiator 400 independent of the operation of the actuators and / or airbags configured on the body massage unit 101 and / or the actuators and / or airbags configured on the leg massage unit 103.

[0309] In contrast, when operating the light therapy mode, the control unit 120 can control the light irradiator 400 to irradiate light in a quasi-linked or linked manner with the movement of the massage unit. In other words, the control unit 120 can simultaneously control the movement of the actuators and / or airbags disposed on the body massage unit 101 and / or the actuators and / or airbags disposed on the leg massage unit 103 included in the massage device 100, and the movement of the light irradiator 400. That is, according to an embodiment of this disclosure, the control unit 120 can cause the mechanical stimulation generated by the mechanical massage movement performed on the user's body and the optical stimulation generated by the light irradiation movement to work in combination, thereby providing a more effective therapeutic and cosmetic effect to the body.

[0310] According to one embodiment, the body massage unit 101 may include an adjustable backrest 1011, and the massage module 170 may be disposed on the backrest 1011. Adjusting the angle of the backrest 1011 of the body massage unit 101 refers to adjusting the angle of the backrest 1011 relative to the base frame 112 included in the frame portion 110, but is not limited thereto. For example, the angle of the backrest 1011 may be the angle between the mounting surface (or support surface, ground) of the massage device 100 and the backrest 1011.

[0311] For example, when the massage device 100 operates in the first care mode, the control unit 120 can control the angle of the backrest 1011 to be adjusted according to a preset time interval. The preset time interval may include at least three time intervals. For example, the at least three time intervals may include a first interval, a second interval, and a third interval. The flow of the first interval, the second interval, and the third interval may be continuous. According to one embodiment, the first interval, the second interval, and the third interval may be set to have the same time interval (e.g., 10 minutes), but this is not a limitation. Furthermore, the above is merely an example; it should be noted that the preset time interval may also be configured to include four or more time intervals.

[0312] The control unit 120 can control the angle adjustment of the backrest 1011 according to the preset time interval corresponding to the selected light care mode.

[0313] For example, when the massage device 100 operates in the first care mode M1, the control unit 120 can control the angle of the backrest 1011 according to the flow of a set time interval, so that the backrest 1011 gradually tilts backward. As mentioned above Figure 10 As described above, the angle of the backrest 1011 can be in a state on a virtual line L1 centered on the main hinge axis (MA) (e.g.: Figure 10 The first state (0% tilt state) and the state on the virtual line L2 (e.g.: Figure 11The angle of the backrest 1011 can be adjusted between the second state (100% tilt state). In the first care mode M1, the angle of the backrest 1011 can be gradually tilted from L1 to L2 according to the set time interval (e.g., first interval value third interval).

[0314] The more the backrest 1011 tilts backward, the closer at least part of the user's body will be to the backrest 1011 under the influence of gravity, or the more it will be biased toward the upper part of the massage device 100 (i.e., the side of the light emitter 400).

[0315] The massage device 100 disclosed herein can more precisely adjust the area reached by the light irradiator 400 by adjusting the angle of the backrest 1011, resulting in a more uniform skin improvement effect.

[0316] For example, at the initial moment of the first care mode M1, the backrest 1011 can be positioned on the virtual line L1 (e.g.: Figure 10 In the first state (0% tilt state), the light irradiator 400 can perform light irradiation on the user's facial area under the control of the control unit 120.

[0317] In addition, in the first care mode M1, the light irradiator 400 can be in the position for irradiating light on the first body part (e.g., the facial area) under the control of the control unit 120, that is, in the sliding exit state. However, even in the sliding exit state, the light may still not be able to fully irradiate a part of the first body part (e.g., the facial area) (e.g., the chin).

[0318] After the initial moment of the first care mode M1, the backrest 1011 can tilt from virtual line L1 toward virtual line L2. At this time, the user's body will tilt towards the upper part of the massage device 100 (i.e., the side of the light irradiator 400) due to gravity. As described above, because the body tilts towards the light irradiator 400, the parts of the first body part (e.g., the facial area) that are not sufficiently illuminated (e.g., the chin area) can also be illuminated evenly with other parts. Thus, it is possible to avoid the light being concentrated only in a local area of ​​the body part, and by irradiating the light evenly to a wider area, the skin improvement effect can be evenly achieved overall.

[0319] In addition, the advantage of adjusting the angle of the backrest 1011 is that as the user's body fits more closely to the backrest 1011, the relative distance between the body surface and the light irradiator 400 can remain constant, thereby enabling more precise control over the intensity and angle of the light.

[0320] In addition, by more precisely controlling the positions of the body massage unit 101, the leg massage unit 103, and the light irradiator 400, the control unit 120 can not only achieve uniform light irradiation, but also provide concentrated care for localized areas.

[0321] In addition, when the massage device 100 operates in the second care mode M2, the control unit 120 can adjust the backrest 1011 to a preset lying position, or control the backrest 1011 to maintain the set lying position.

[0322] According to one embodiment, the control unit 120 can adjust the angle of the backrest 1011 to its maximum at the start of a care mode (e.g., the second care mode M2) instead of gradually tilting the backrest 1011 backward over time, and maintain this angle even when the patient is in a lying position (e.g., in a reclining position). Figure 11 Care is performed on body parts (e.g., second body parts) in the second state (100% tilt state).

[0323] The actions for adjusting the backrest angle 1011 in the first and second care modes will be explained in detail with reference to Tables 1 to 6 below.

[0324] According to one embodiment, the light irradiator 400 irradiates light according to a preset time interval, but the control unit 120 can control the light irradiator 400 to irradiate light with a first intensity higher than other intervals during the initial entry interval. For example, when the preset time interval includes consecutive first, second, and third intervals, the control unit 120 can control the light irradiator 400 to irradiate the strongest light during the first interval (initial entry interval). In other words, compared to the second and third intervals, the control unit 120 can control the light irradiator 400 to irradiate the strongest light during the first interval (initial entry interval) of the light care mode, thereby rapidly improving the skin care effect on the user from the start of the light care mode operation and increasing user satisfaction with the light care mode.

[0325] According to one embodiment, when running the light care mode, the control unit 120 can first control the body massage unit 101 and leg massage unit 103 of the massage device 100 to enter the initial first state (0% tilt state) so that the user can sit in the massage device 100 in a comfortable posture, and then concentrate on performing skin improvement by irradiating light with the maximum intensity.

[0326] The light irradiator 400 irradiates light according to a preset time interval, but the control unit 120 can set it to irradiate light at a second intensity lower than the first intensity (e.g., approximately 50% of the first intensity) in intervals other than the initial interval. For example, in the second and third intervals, it can be set to irradiate light at an intensity lower than that irradiated in the first interval. By controlling the light irradiator 400 to irradiate light at a lower intensity than the initial entry interval, the control unit 120 allows the user to receive skin care and massage stimulation in a more stable and comfortable state. According to one embodiment, in light care mode, the control unit 120 can first maximize the light irradiation for the user to provide concentrated care for the user's skin, then reduce the intensity of the light irradiated by the light irradiator 400 to provide a skin improvement effect with low fatigue caused by light, and finally control the tilt of the body massage section 101 and leg massage section 103 of the massage device 100 to simultaneously provide light and massage to guide the user to relieve tension, rest, and sleep.

[0327] For example, compared to other skin areas (e.g., the face), the scalp's absorption and scattering of light may differ due to the presence of hair. Furthermore, if the light irradiator 400 continuously irradiates the scalp at high output power, excessive heat buildup may occur, causing discomfort to the user. Therefore, when executing, for example, the second treatment mode M2, the control unit 120 can initially irradiate the scalp at a higher brightness to maximize penetration, and then, after a predetermined time, reduce the brightness to prevent the light irradiator 400 from generating excessive heat, thereby reducing scalp stimulation and maintaining optimal treatment results.

[0328] The intensity of light can refer to the amount of light. The greater the light intensity, the more LEDs in the optical module 430 of the light illuminator 400 can be turned on. However, it is not limited to this. The greater the light intensity, the greater the brightness of the multiple LEDs in the optical module 430 of the light illuminator 400, or the greater the intensity of the supply current (or voltage) provided to the optical module 430.

[0329] According to one embodiment, the massage device 100 may further include a leg massage unit 103 disposed at the other end of the body massage unit 101, the angle of which is adjustable, and a leg massage module for massaging the user's legs.

[0330] The control unit 120 can adjust the angle of the leg massage unit 103 according to a preset time interval. According to one embodiment, the leg massage unit 103 may include a first leg rest 1031a and a second leg rest 1031b, and the control unit 120 can control the angles of the first leg rest 1031a and the second leg rest 1031b independently, relatively, quasi-linked, or linked to each other.

[0331] In this disclosure, the control unit 120 can control the tilting motion of the linked leg rest 1031 in conjunction with the tilting motion of the backrest 1011.

[0332] According to one embodiment, when a first care mode for irradiating light onto a first part of the user's body is run according to the user's input, the control unit 120 can control the execution of a cyclical action that causes the angle of the leg rest 1031 of the leg massage unit 103 to change sequentially and repeatedly, corresponding to the action of tilting the backrest 1011 to an angle above a preset angle.

[0333] For example, as mentioned above Figure 13 As described above, the cyclic action can refer to the action of changing the angle (or changing simultaneously) or length of the first leg rest 1031a and the second leg rest 1031b included in the leg rest 1031.

[0334] According to one embodiment, the control unit 120 can control the leg massage unit 103 to adjust its angle relative to the body massage unit 101 according to a preset time interval, and can control the cyclic action to be performed within a set interval after the initial entry interval. In order to improve the skin care effect, the control unit 120 can control the irradiation of stronger light in the initial stage of the light care mode, and then, in order to relieve tension and enhance the resting effect, it can control the leg massage unit 103 to perform the cyclic action based on the action of adjusting the angle of the leg rest part 1031 of the leg massage unit 103.

[0335] In this disclosure, the control unit 120 links the tilting motion of the backrest 1011 and the tilting motion of the leg rest 1031 with the light irradiation of the light irradiator 400, thereby keeping the user's body in an optimal posture to provide the effect of improving light transmittance and absorption.

[0336] According to one embodiment, in the initial phase of the first care mode M1, the control unit 120 can control the light irradiator 400 to irradiate the strongest light (e.g., the light of the first intensity). In conjunction with this, the control unit 120 can control the position of the backrest 1011, fixing its angle at a first angle (e.g., an angle of approximately 60%) relative to a virtual line L1. Additionally, in conjunction with this, the angle of the leg rest 1031 can be adjusted, fixing its position at a second angle (e.g., an angle of approximately 30%) relative to a virtual line L3. The initial phase of the first care mode M1 is a phase for concentrated skin improvement. The control unit 120 controls the light intensity of the light irradiator 400 to the maximum (e.g., 100%), but to ensure the user can comfortably sit on the massage device, the angles of the backrest 1031 and the leg rest 1031 can be fixed. Here, 60% can refer to... Figure 10 Between virtual lines L1 and L2, within the equally proportionally divided angular intervals, from L1 at a 60% inclination, 30% can be... Figure 10 Between the virtual lines L3 and L4, in the angular intervals divided by equal proportions, the inclination is 30% from L3. It should be noted that the examples of the angles above (i.e., 60% and 30%) are for illustrative purposes only and are not intended to limit the scope of this disclosure.

[0337] According to one embodiment, after the initial interval of the first care mode M1, the control unit 120 can control the reduction of light intensity because prolonged exposure of the light irradiator 400 to high-intensity light may lead to increased fatigue in the user's body, especially their eyes. This reduction in light intensity can be controlled by simultaneously or subsequently adjusting the angles of the backrest 1011 and leg rest 1031. For example, the interval after the initial interval of the first care mode M1 could be an interval for improving skin with low fatigue. In this case, the control unit 120 can control the reduction of light intensity from the light irradiator 400 (e.g., 50%), but to allow the user to receive care in a more comfortable state, the angle of the backrest 1031 can be further adjusted (e.g., adjusting the backrest 1011 to approximately 100% tilt). Furthermore, to further adjust the angle of the backrest 1031, the control unit 120 can also additionally or alternatively adjust the angle of the leg rest 1031 (e.g., performing a cyclic operation on the leg rest 1031).

[0338] The control unit 120 controls the angles of the backrest 1011 and the leg rest 1031, allowing the user to receive care in a comfortable state. As described above, the control unit 120 controls the light irradiator 400 and adjusts the angles of the backrest 1011 and the leg rest 1031 in a quasi-linked or linked manner, enabling the user to relieve tension, rest, and sleep while maintaining smooth blood circulation.

[0339] According to one embodiment, the control unit 120 can also control the massage device 100 to perform a pre-massage action for relaxing muscles by means of at least one of the body massage module, leg massage module, arm massage module and airbag before the backrest 1011 begins to tilt.

[0340] For example, when a user selects a light care mode based on their input, the control unit 120 can perform a massage action before entering the light care mode, thereby relieving the user's tension in advance. Before performing skin care actions, the control unit 120 can perform a mechanical massage through the movement of actuators included in the massage module and the expansion or contraction of airbags, which can improve blood circulation and enhance the skin improvement effect brought by the light care mode.

[0341] According to one embodiment, when the control unit 120 operates in a second care mode M2 ​​for irradiating light onto a second body part of the user based on user input, the angle of the leg rest portion 1031 of the leg massage unit 103 can be set to perform a gradually rising lifting motion. For example, during the lifting motion, the angle of the leg rest portion 1031 can be increased to... Figure 11 The position corresponding to the virtual line L4. During the lifting action, the control unit 120 can control the leg rest 1031 to maintain its position at the maximum angle.

[0342] According to one embodiment, the control unit 120 can control the light irradiator 400 to irradiate the strongest light (e.g., light of the first intensity) in the initial range of the second care mode M1. Furthermore, the control unit 120 can adjust the angle of the backrest 1011 to its maximum, assuming a reclining position (e.g., ...). Figure 11 The care of body parts (e.g., a second body part) is performed in the second state (100% tilt state). In this state, the control unit 120 controls the leg rest 1031 to rise to the level of the second body rest. Figure 11At the position corresponding to the virtual line L4, blood flow can be concentrated towards a second body part (e.g., the scalp area). That is, when in the second care mode M2, the control unit 120 can control the angle of the leg rest 1031 of the leg massage unit 103 to be higher than the angle in the first care mode M1, thereby causing the user's blood flow to concentrate towards the scalp side. According to one embodiment, when the second care mode M2 ​​is raised, the legs may be positioned higher than the user's upper body. The control unit 120 can control the light irradiator 400 to perform light irradiation while the user's legs are positioned higher than the user's upper body to concentrate blood flow towards the scalp side, thereby improving the effect of scalp care.

[0343] In the first care mode M1, the control unit 120 can control the leg massage unit 103 to perform cyclic movements to provide the user with relaxation and rest. In contrast, in order to improve the stability of the user's posture and to enhance the concentration of blood flow to the scalp (second body part), which is closer to the top of the body than the face (first body part), in the second care mode M2, the leg massage unit 103 can be controlled not to perform cyclic movements, but to maintain the raised leg angle.

[0344] According to one embodiment, when a user's legs are raised simultaneously, it may cause dizziness and / or muscle damage. Therefore, the control unit 120 can first raise one of the first leg rest 1031a and the second leg rest 1031b included in the leg massage unit 103, then raise the other, and then raise both the first and second leg rests 1031a and 1031b. Thus, the control unit 120 can sequentially raise the first and second leg rests 1031a and 1031b, thereby solving the aforementioned problem. Furthermore, by finally raising both the first and second leg rests 1031a and 1031b, blood flow is concentrated towards the scalp, enhancing the light's effect on the scalp.

[0345] According to one embodiment, when the control unit 120 operates according to the user's input in at least one of a first care mode M1 for irradiating light onto a first part of the user's body and a second care mode M2 ​​for irradiating light onto a second part of the user's body, it can control at least one of the actions of the actuators included in the body massage unit and the expansion or contraction of the airbag in accordance with at least one care mode.

[0346] In order to improve the skin care effect of the light irradiator 400, the control unit 120 controls the user's body to move closer to or toward the optical module 430 of the light irradiator 400 by controlling at least one of the actions of the actuators included in the massage module and the expansion or contraction of the airbag.

[0347] For example, when the massage device operates in the first care mode M1 or the second care mode M2, the control unit 120 can control the massage module included in the body massage unit 101 to perform an action of pushing the user's first and / or second body parts from the rear towards the upper side of the body massage unit 101, so that the first and / or second body parts are closer to the light irradiator 400. Alternatively, for performing the action of bringing the first and / or second body parts closer to the light irradiator 400, the control unit 120 can additionally or alternatively control the execution of an action using the airbag included in the body massage unit 101 to rotate the user's pelvis to the left or right, thereby causing the first and / or second body parts to face the light irradiator.

[0348] According to one embodiment, when the massage device 100 operates in a first care mode M1 or a second care mode M2, the control unit 120 can control the change of the body parts irradiated by the light irradiator 400 by performing at least one of the following actions: turning the user's head to the left or right using the actuators included in the body massage unit 101; raising the user's left or right leg using the actuators included in the leg massage unit 101; and massaging the user's lower limbs with the body massage unit and / or the leg massage unit. By performing at least one of the following actions, the control unit 120 can more accurately determine the body parts irradiated by the light. Therefore, not only can a uniform care effect be obtained for the entire area of ​​the body, but in some cases, a concentrated care effect can also be obtained for specific areas.

[0349] According to one embodiment, when the control unit 120 operates in the second care mode M2, compared to operating in the first care mode M1, the control unit 120 can control the working position of the actuators and / or airbags included in the body massage unit 101 in a higher position relative to their position in the first care mode M1 (e.g., closer to the user's head). The working position of the actuators and / or airbags included in the body massage unit in the second care mode M2 ​​may be different from that in the first care mode M1 (e.g., possibly higher). According to one embodiment, the second body part (the object of care in the second care mode M2) may be located at a higher position than the first body part (the object of care in the first care mode M1) (e.g., from a structural perspective, the scalp area is located at a higher position than the face area). Therefore, in the second care mode M2, where care is performed on the body part at a higher position, compared to the first care mode M1, the user's body is moved towards the upper side of the massage device 100, bringing it closer to the light irradiator 400, which produces a better effect on phototherapy.

[0350] According to this disclosure, a control method for a massage device according to the above embodiments can be provided. The control method for the massage device may include actions such as selecting a light care mode of the massage device based on user input, and controlling the massage actions of the body massage unit 101 in conjunction with the light irradiation actions of the light irradiator 400 according to the selected light care mode. The control method for the massage device may also include actions such as the control unit 120 controlling the light irradiator to irradiate light onto at least one of a first body part and a second body part different from the first body part of the user.

[0351] According to one embodiment, the control unit 120 can acquire user input sent from the input unit 140 and / or the massage device control device control device 200, and based on the acquired user input, control the massage device 100 with a light care mode corresponding to the user input among multiple massage modes. The control unit 120 operates the selected light care mode and can control various structures of the massage device 100 based on the light care mode. For example, the control unit 120 controls the posture and massage action of at least one of the body massage unit 101 and the leg massage unit 103 based on the light care mode, and can control the drive of the light irradiator 400. According to one embodiment, for the above-mentioned control action, the control unit 120 can also additionally or alternatively control the posture and massage action of the arm massage unit 102. Thus, the control unit 120 can provide massage to the user through at least one massage unit while also irradiating light through the light irradiator 400, thereby improving the user's skin.

[0352] According to one embodiment, the massage device 100 may further include a guidance module. The guidance module may be, for example, a text-to-speech (TTS) module. According to one embodiment, the guidance module may be… Figure 1The structure included in the audio output module 150. The guidance module may be configured to convert information corresponding to the actions of the massage device 100 into speech for output, or into text for output via the user input unit 140, thereby guiding the user. For example, the control unit 120 may control the guidance module to guide or output information related to the actions of the massage device associated with at least one of a first care mode for irradiating light onto a first body part and a second care mode for irradiating light onto a second body part, either by speech or by converting it into text and output via the user input unit 140. In this case, the information related to the actions of the massage device may include information about the body parts of the user's body used for irradiating light. The information about the body parts used for irradiating light may include at least one of first information guiding the user to move in a manner that irradiates light onto the entire area of ​​the first and / or second body parts and second information guiding the user to move in a manner that irradiates light onto a portion of the first and / or second body parts.

[0353] For example, when the massage device 100 operates in a first care mode or a second care mode, the control unit 120 can control the guidance module to output audio guidance information related to the actions of the massage device 100 performed in the current care mode accepted by the user. For example, when it is desired to shine light on the side of the user's face (first body part) in the first care mode, the guidance module can be controlled to output audio such as "Please look to the left" or "Please look to the right," thereby guiding the user to look to the left or right based on the user's facing direction. For example, when it is desired to shine light on the user while the user's body is tilted in the second care mode, the control unit 120 can control the guidance module to output audio such as "Please lie quietly in a tilted position," so that the user keeps the body tilted and the scalp (second body part) facing down. In addition, the examples described above can be applied in different ways. The guidance module can output not only audio but also text through the output unit 140. By outputting information related to the actions of the massage device as described above through the guidance module, the skin care effect of the massage device 100 performing the light care mode can be further improved.

[0354] According to one embodiment, in order to assist in achieving the above-mentioned action of turning the user's head to the left or right, the control unit 120 may perform at least one of the following actions: lifting the left or right leg, massaging the lower limbs, and outputting audio related to the action of the massage device 100.

[0355] For example, while the user's right shoulder is secured by inflating the shoulder airbags in the first and second shoulder airbags corresponding to the user's right side, the control unit 120 can push the user's left back by inflating the back airbags in the first and second back airbags corresponding to the user's left side, thereby causing the user's body to rotate to the right, and thus allowing the user's head to rotate to the right. At this time, the control unit 120 can also inflate the pelvic airbags in the first and second pelvic airbags corresponding to the user's left side at at least one point in time before, after, and during the inflatation of the back airbags, to assist in the rotation of the user's body using the back airbags.

[0356] In addition, the control unit 120 may perform at least one of the following actions at at least one time point before, during, or after turning the user's head to the right (or at least one time point before, during, or after inflating the left back airbag): lifting the leg massage unit corresponding to the user's right leg and outputting audio (e.g., voice) that turns the user's head to the right.

[0357] As another example, while the user's left shoulder is fixed by inflating the shoulder airbags in the first and second shoulder airbags corresponding to the user's left side, the control unit 120 can push the user's right back by inflating the back airbags in the first and second back airbags corresponding to the user's right side, thereby causing the user's body to rotate to the left, and thus allowing the user's head to rotate to the left. At this time, the control unit 120 can also inflate the pelvic airbags in the first and second pelvic airbags corresponding to the user's right side at at least one point before, after, and during the inflating of the back airbags, to assist in the rotation of the user's body using the back airbags.

[0358] Additionally, the control unit 120 may perform at least one of the following actions at at least one time point before, during, or after rotating the user's head to the left (or at least one time point before, during, or after inflating the left back airbag): lifting the leg massage unit corresponding to the user's left leg and outputting audio (e.g., voice) that rotates the user's head to the left.

[0359] Therefore, the control unit 120 can perform at least one of the following actions—leg lifting, lower limb massage, and audio output—while moving the body part to be irradiated in a specific direction via the actuator and / or airbag of the body massage unit, so as to make the body part to be irradiated move smoothly. This allows the user's body to move quickly and accurately by assisting the movement of the body part to be irradiated, ensuring that light is irradiated onto different body parts, and improving the skin improvement effect of the light irradiation target area.

[0360] The following is for reference Figure 15 to Figure 19The embodiments of the massage device 100 according to the present disclosure will be described in more detail, including the control method (or operation method) of the massage device.

[0361] Figure 15 This is a flowchart illustrating the operation of a massage device according to an embodiment of the present disclosure in various modes.

[0362] The control unit 120 can control the light irradiator 400 to operate in at least one of the following care modes: a first care mode M1 for irradiating a first body part and a second care mode M2 ​​for irradiating a second body part. For example, when the user input is a light care mode, the control unit 120 can control the light irradiator 400 to perform light irradiation according to the setting value corresponding to the light care mode. For example, when the user input is not a light care mode (i.e., in the third mode M3), the control unit 120 identifies whether there is an additional input for turning on the light irradiator 400, and when the light irradiator 400 is turned on, it can control the light irradiator 400 to perform light irradiation according to the preset setting option.

[0363] When the user selects the first nursing mode M1 through input, such as Figure 15 As shown, in the first nursing mode M1, the following actions can be performed: 511 adjusting the angle of the backrest 1011, 513 the light irradiator 400 irradiating light according to a preset time interval, 515 adjusting the angle of the leg rest 1031 according to a preset time interval, and 517 controlling the actuator and at least one of the following actions: inflating or contracting the airbag.

[0364] When the user selects the second nursing mode M2 ​​through input, such as Figure 15 As shown, in the second nursing mode M2, the following actions can be performed: 521 adjusting the angle of the backrest 1011; 523 irradiating the light irradiator 400 according to a preset time interval; 525 adjusting the angle of the leg rest 1031 according to a preset time interval; and 527 controlling at least one of the following actions: the action of the actuator and the expansion or contraction of the airbag.

[0365] When the user selects the third mode M3 through input, such as Figure 15As shown, the following actions can be performed: 531, determining (or confirming) whether the light irradiator 400 is turned on; 533, when the light irradiator 400 is turned on, irradiating light with a predetermined intensity or varying intensity according to a preset setting; 535, turning off the light irradiator after irradiating light for a preset time period; or 537, when receiving an input to turn off the massage device 100 or the light irradiator 400, turning off the massage device 100 or the light irradiator 400. As described above, turning on the light irradiator 400 can mean activating the optical module 430 of the light irradiator 400 to irradiate light. Conversely, turning off the light irradiator 400 can mean not activating the optical module 430 to prevent light irradiation.

[0366] Although Figure 15 The actions are shown in sequence, but this is only an example. In different embodiments, one or more actions of the above-mentioned related components may be omitted, or one or more other actions may be added. It should be noted that, in different embodiments, the actions may be performed sequentially, in parallel, repeatedly, or heuristically, and one or more actions may be performed in different orders, omitted, or one or more other actions may be added.

[0367] like Figure 15 As shown, although the first nursing mode M1 and the second nursing mode M2 ​​include similar actions, they may also include different actions in detail.

[0368] The following is for reference Figure 16 to Figure 19 The operation (or operation method, control method) of the massage device under the first nursing mode M1 and the second nursing mode M2 ​​is described in more detail.

[0369] Figure 16 This is a flowchart illustrating the actions of a first nursing mode according to an embodiment of the present disclosure. Figure 17 This is a diagram illustrating an example of the operation of the backrest, leg massage unit, and light irradiator in a first care mode according to an embodiment of the present disclosure. Figure 18 This is a flowchart illustrating the actions of a second nursing mode according to an embodiment of the present disclosure. Figure 19 This is a diagram illustrating an example of the operation of the backrest, leg massage unit, and light irradiator in a second care mode according to an embodiment of the present disclosure.

[0370] First, the first care mode M1 (e.g., the first body part (e.g., the face) care mode) will be explained.

[0371] As mentioned above Figure 15In the first nursing mode M1, the operation of the massage device 100 disclosed herein may include an action 511 of adjusting the angle of the backrest according to a preset time interval, an action 513 of irradiating the light irradiator according to a preset time interval, an action 515 of adjusting the angle of the leg rest 1031 according to a preset time interval, and an action 517 of controlling at least one of the operation of the actuator and the expansion or contraction of the airbag. These actions are executed under the control of the control unit 120.

[0372] against Figure 15 Actions 511, 513, 515, and 517 included in the first nursing mode M1 can be performed additionally or alternatively. Figure 16 Actions 611, 613, 615, and 617 are included in the first nursing mode M1.

[0373] Simultaneously refer to Figure 16 and Figure 17 The alternative action 511 can perform the action 611 of tilting the backrest angle according to a preset time interval. If the angle of the backrest 1011 is not tilted to the angle set in the first interval of the first care mode M1, the control unit 120 can control the backrest 1011 to tilt to the angle of the first interval. If the angle of the backrest 1011 is the same as the angle set in the first interval of the first care mode M1, the control unit 120 can control the backrest 1011 to maintain the corresponding angle. If the angle of the backrest 1011 is greater than the angle set in the first interval of the first care mode M1, the control unit 120 can control the backrest 1011 to tilt to the angle of the first interval.

[0374] The light irradiation action can be performed simultaneously with the backrest angle tilting action 611. The control unit 120 controls the backrest angle tilting action 611, and in a quasi-linked or linked manner, controls the light irradiator 400 to perform light irradiation. According to one embodiment, the control unit 120 can control the light irradiator 400 to irradiate light in a light irradiation mode corresponding to the first care mode M1. Furthermore, the control unit 120 can control the position of the sliding part 420 of the light irradiator 400 so that the light irradiator 400 irradiates the first body part corresponding to the first care mode M1. For example, the control unit 120 can control the sliding part 420 of the light irradiator 400 to be in the sliding-out state position in the first care mode M1. While the control unit 120 can control the position of the sliding part 420, it is not limited to this. For example, while running the first care mode, the control unit 120 can provide the user with guidance information to change (or maintain) the sliding part 420 to the sliding-out state. At this time, guidance information can be provided through visual content via the input section 140 of the massage device 100 and the display included in at least one of the user devices used by the user, and / or through auditory content via the guidance module. The audiovisual content may be prompts such as: "Please pull the LED cover forward", "Please pull the light irradiator forward", "Please keep the LED cover in the forward-pulled state", "Please keep the light irradiator in the forward-pulled state", etc.

[0375] Reference Figure 16 and Figure 17 For action 513, actions 613 (or alternatively for action 517) can be performed to bring the user's first body part (e.g., facial area) closer to the light irradiator and actions 615 (to turn the side of the user's first body part (e.g., facial area) toward the light irradiator). To further enhance the skin care effect of the light irradiator 400, the control unit 120 can control the massage module 170 and / or airbags of the body massage unit 101 to bring the first body part (e.g., facial area) closer to the light irradiator 400 or to turn the side of the user's first body part (e.g., facial area) toward the light irradiator 400.

[0376] For example, when the action is performed in the first care mode, the control unit 120 can control the body massage module 170 and / or airbag included in the body massage unit to perform at least one of the following actions: pushing the user's first body part from behind (e.g., behind the back or neck) to bring the user's first body part closer to the light irradiator 400 (corresponding to action 613) and twisting a part of the user's body (e.g., turning the pelvis to the left or right) through the airbag included in the body massage module to bring the user's first body part toward the light irradiator 400 (corresponding to action 615).

[0377] Specifically, the control unit 120 controls (drives or stops) the movement of at least one of the kneading actuator, tapping actuator, back-and-forth movement actuator XD, and up-and-down movement actuator included in the massage module 170 of the body massage unit 101, thereby bringing a first body part (e.g., the facial area) closer to the light irradiator 400. More specifically, as described above... Figure 4 As described above, the control unit 120 can control the tapping module and / or the forward and backward movement actuator XD to move the massage unit 172 in the direction from the XD0 stage to the XD5 stage, thereby pushing it from the back of the user's back or the back of the neck, bringing the face closer to the light irradiator 400.

[0378] More specifically, the control unit 120 controls the airbag to twist the user's first body part, causing the first body part or its peripheral portion (e.g., the side of the first body part) to face the light irradiator 400. More specifically, see... Figure 6 To fix one shoulder in a fixed state, the control unit 120 inflates one of the first and second shoulder airbags 191a and 191b included in the airbag system. Then, the control unit 120 rotates the user's body so that the user's face faces the light irradiator 400 by inflating the airbag below the other shoulder in the first and second back airbags 192a and 192b. Alternatively or additionally, the control unit 120 can assist the body rotation by controlling one of the first and second pelvic airbags 195a and 195b.

[0379] As described above, when operating in the first care mode, the control unit 120 can perform concentrated care on the first body part and / or the area around the first body part by controlling the body massage module 170 and / or airbags included in the body massage unit.

[0380] Reference Figure 16 and Figure 17 Alternatively, for action 513 (or alternatively for action 517), action 617 stimulating the user's sole can be performed. To stimulate the user's sole, control unit 120 can control the leg massage module and / or airbags included in leg massage unit 103 to stimulate the sole. Specifically, control unit 120 can control the concentration of blood flow to the user's first body part by controlling the airbags. More specifically, control unit 120 can stimulate the user's lower limbs (e.g., soles) by causing the first and second instep airbags 199a and 199b. However, it is not limited to the airbags described above. Various other embodiments can be applied to stimulate the lower limbs, such as inflating all leg airbags (e.g., calf, ankle, instep).

[0381] Additionally, for example, the control unit 120 can adjust the angle of the leg massage unit 103 to allow the user to experience the light therapy mode in a more comfortable state. According to one embodiment, the control unit 120 can control the leg massage unit 103 to perform a cyclical movement (e.g., a robotic cyclical movement) in which the first leg rest 1031a and the second leg rest 1031b alternately cross each other. By controlling the leg massage unit 103 to perform cyclical movements, the control unit 120 can more stably maintain the user's body balance. Hereinafter, referring to Tables 1 to 3, the actions of each step in the first care mode (e.g., the first body part (e.g., the face) care mode) will be described in detail according to the first embodiment.

[0382] Table 1

[0383] Table 2

[0384] Table 3

[0385] Table 1 shows the actions of each component in the first interval within the preset time interval, Table 2 shows the actions of each component in the second interval within the preset time interval, and Table 3 shows the actions of each component in the third interval within the preset time interval. The first, second, and third intervals can sequentially and continuously show the passage of time. According to one embodiment, the first, second, and third intervals can each be allocated to 10 minutes, but this can be adjusted according to the embodiment. Referring to Table 1, in the preparation phase, when the user selects the first care mode, the light source of the light irradiator 400 can be automatically turned on. The automatically turned-on light source continues during the first, second, and third intervals, and can then be automatically turned off at the end of the third interval. For example, the control unit 120 can control the light irradiator 400 to automatically turn off 30 minutes after the automatically turned-on light source.

[0386] In Tables 1 to 3, each interval can be further divided into multiple stages, such as the first stage, the second stage, and the third stage.

[0387] In Tables 1 to 3, the distinctions between the first, second, and third intervals can be set corresponding to the angle of the backrest 1011 of the body massage unit 101. In the first interval, the backrest 1011 can be tilted approximately 60% (e.g., the backrest 1011 is located at...). Figure 17(The state on the virtual line L5), in the second interval, the backrest 1011 can recline approximately 80%, and in the third interval, the backrest 1011 can recline approximately 100% (e.g., the backrest 1011 is located at...). Figure 17 (The state on the virtual line L2). When the user leans against the backrest 1011, their body will be pressed against the backrest 1011 or tilted towards the upper part of the massage device 100 (i.e., the side of the light irradiator 400) under the influence of gravity. Therefore, the facial area reached by the light irradiator 400 can be more precisely adjusted, ultimately resulting in a uniform skin improvement effect on all areas. The 60%, 80%, and 100% mentioned above can be used as an example to aid understanding.

[0388] Specifically, referring again to [Table 1], in step 1 of stage 1 of the first interval, in order to care for the lower facial area (e.g., chin) and the peripheral facial area (e.g., neck), the backrest 1011 can be tilted at an angle of 60%. Correspondingly, in order to prevent injury and maintain body balance, the leg rest 1031 can be raised at an angle of approximately 30%. In step 2 of stage 1 of the first interval, before the formal care action according to the first care mode, muscles can be relaxed using pre-action actions and pre-massage actions for blood circulation can be performed. According to one embodiment, in step 2 of stage 1 of the first interval, the user's sitting posture can be changed during the pre-massage action by operating the pelvic airbag or a portion of the pelvic airbag. In step 3 of stage 1 of the first interval, the shoulders are fixed by the shoulder airbags to prevent the upper body from swaying, and the massage module acupressures and / or pushes the lumbar spine of the back so that the optical module 430 of the light irradiator 400 faces the front of the face. At this time, the massage module can move along the erector spinae line, on the X-axis (X-Direction, XD) (e.g.: Figure 4The light is repeatedly pushed along the X-axis, bending the entire body into an arch shape and tilting the face backward (or upward), so that the optical module 430 of the light irradiator 400 faces the front of the face. Additionally, in step 3 of stage 1 of the first section, the intensity of the light irradiated by the light irradiator 400 can be reduced by approximately 50%, preventing light from dazzling the user's eyes. In step 4 of stage 2 of the first section, the fascial structure of the whole body is adjusted by the air bladders on both sides of the pelvis, correcting facial asymmetry. Furthermore, by applying pressure and / or pushing to the neck area, the face can be turned upward, allowing for even illumination of the area below the chin. In step 5 of stage 3 of the first section, the air bladders on the left back and left pelvis are inflated, so that the left side of the face faces the optical module 430 of the light irradiator 400. In step 6 of stage 3 of the first section, the air bladders on the right back and right pelvis are inflated, so that the right side of the face faces the optical module 430 of the light irradiator 400. According to other embodiments, the control unit 120 can control the right side of the face to face the optical module 430 of the light irradiator 400 in step 5 of the third stage of the first interval, and control the left side of the face to face the optical module 430 of the light irradiator 400 in step 6 of the third stage of the first interval. In step 7 of the third stage of the first interval, all leg airbags and rollers can be driven to stimulate the soles of the feet. By driving all leg airbags and rollers to stimulate the lower limbs (e.g., the soles of the feet), the blood circulation effect of the lower limbs can be improved. In the first interval, acupressure is performed on the shoulders and back. At this time, the position of acupressure on the shoulders and back can gradually rise from the user's waist towards the head over time.

[0389] Specifically, referring to both [Table 2] and [Table 3], the second and third intervals are also divided into the first to third stages, and are the same as the first interval in [Table 1], which can be further subdivided into a total of seven steps. In the second interval of [Table 2], the backrest angle 1011 will be further tilted to approximately 80%, and in the third interval of [Table 3], the backrest angle 1011 will be further tilted to approximately 100%. Referring to the second interval of [Table 2], acupressure on the neck area can be performed with the pelvis fixed, and the acupressure position is higher than the acupressure position on the shoulders and back in the first interval. In the third interval of [Table 3], the acupressure position can be lowered relative to the second interval, thereby performing acupressure on the back area and pelvis. In [Table 2] and [Table 3], the angle of the leg massage section 103 may be increased; for example, the angle of the leg massage section 103 may be repeatedly changed in the order of approximately 30% → 60% → 90%. The first leg rest 1031a and the second leg rest 1031b included in the leg massage unit 103 can perform a cyclical motion with changing angles while crossing each other to the left and right. The actions described in Tables 1 to 3 are shown in simplified form in Table 4 below.

[0390] Table 4

[0391] Referring to Table 4, in the first care mode M1, at the beginning of the care mode, to achieve the maximum effect, the brightness intensity is irradiated at 100% for a predetermined time (e.g., during the first and second phases of the first interval). After the predetermined time has elapsed (e.g., starting from the third phase of the first interval), the brightness intensity can be reduced by 50% to improve user comfort. The angle of the backrest 1011 can gradually recline (tilt) in each time interval. In the first interval, the angle of the backrest 1011 is relatively smaller compared to other intervals, allowing for care of the lower and / or front areas of the face when the user is naturally seated in the sitting position of the massage device 100. In the second interval, the angle of the backrest 1011 is more tilted than in the first interval, allowing for care of the front and / or upper areas of the face (e.g., the forehead). In the third interval, the angle of the backrest 1011 is more tilted than in the second interval, allowing for care of the upper and / or the very top area of ​​the face. However, it is obvious that the differentiation of facial regions is not limited to this. For example, embodiments could be applied where only the frontal area of ​​the face is treated in the second region, and only the upper area of ​​the face is treated in the third region. Other different embodiments are also possible.

[0392] At the start of the first care mode M1, the leg massage unit 103 is raised and held at a predetermined angle (e.g., approximately 30%) (e.g., held in the first zone). In the second and third zones, cyclical movements (e.g., robotic cyclical movements) are performed to maintain the user's body balance and guide a more comfortable rest. Additionally, in the third zone, to achieve better skin improvement and care than in the first and second zones, this can be achieved by fixing a part of the body (e.g., shoulder airbags) or by controlling the massage module 170 in the forward / backward direction (e.g., XD direction). Figure 4 The massage module 170 moves along the X-axis, causing it to push the body to perform concentrated care on the target area. While the massage module 170 performs different actions in the first to third stages of each interval, it controls the user's facial area towards the optical module 430 of the light irradiator 400, thereby maximizing the effect of the light care mode. As described above, in this embodiment, the time for each interval is illustrated using 10 minutes as an example, but this is only one example, and other different embodiments can be applied. For example, the first interval can be set to 10 minutes, and the second and third intervals can each be set to 15 minutes, and other embodiments can also be applied. According to one embodiment, the first care mode M1 can be repeatedly executed or its duration extended based on user input. When the duration of the first care mode M1 is extended, it is possible to extend the time of a portion of each interval or extend the overall movable time of the first care mode.

[0393] Next, the second care mode M2 ​​(e.g., the second body part care mode) will be explained.

[0394] As mentioned above Figure 15 As described above, in the second nursing mode M2, the operation of the massage device of this disclosure may include an action 521 of adjusting the angle of the backrest 1011, an action 523 of irradiating the light irradiator 400 with light according to a preset time interval, an action 525 of adjusting the angle of the leg massage part 103 according to a preset time interval, and an action 527 of controlling at least one of the operation of the actuator and the expansion or contraction of the airbag.

[0395] against Figure 15 Actions 521, 523, 525, and 527 included in the second nursing model M2 can be performed additionally or alternatively. Figure 18 Actions 621, 623, and 625 are included in the second nursing model M2.

[0396] Simultaneously refer to Figure 18 and Figure 19Alternative action 521 can be performed by tilting the backrest angle 621. If the angle of the backrest 1011 is not tilted to the angle set in the first interval of the second care mode M2, the control unit 120 can control the backrest 1011 to tilt to the angle of the first interval. If the angle of the backrest 1011 is the same as the angle set in the first interval of the second care mode M2, the control unit 120 can control the backrest 1011 to maintain the corresponding angle. If the angle of the backrest 1011 is greater than the angle set in the first interval of the second care mode M2, the control unit 120 can control the backrest 1011 to tilt to the angle of the first interval. The light irradiation action can be performed together with the backrest angle tilting action 621. The control unit 120 controls the execution of the backrest angle tilting action 621, and in a quasi-linked or linked manner, controls the light irradiator 400 to perform light irradiation. According to one embodiment, the control unit 120 can control the light irradiator 400 to irradiate light based on the light irradiation mode corresponding to the second care mode M2. Additionally, the control unit 120 can control the position of the sliding part 420 of the light irradiator 400 so that the light irradiator 400 irradiates the second body part corresponding to the second care mode M2. For example, the control unit 120 can control the sliding part 420 of the light irradiator 400 to be in the sliding-in state position in the second care mode M2. Although the control unit 120 can control the position of the sliding part 420, it is not limited to this. For example, when the second care mode is running, the control unit 120 can provide the user with guidance information prompting them to switch the sliding part 420 to (maintain) the sliding-in state. At this time, the guidance information can provide visual content through the input unit 140 of the massage device 100 and the display included in at least one of the user devices used by the user, and / or provide auditory content through the guidance module. The audiovisual content may be prompts such as: "Please push the LED cover backward," "Please push the light irradiator backward," "Please keep the LED cover in the retracted state," "Please keep the light irradiator in the retracted state," etc.

[0397] Reference Figure 18 and Figure 19For action 523, an additional action 623 (or alternatively for action 527) can be performed to bring the user's second body part (e.g., scalp) closer to the light irradiator. For example, when the action is performed in the second care mode, the control unit 120 can be set to perform at least one of the following actions: turning the user's head to the left or right using the actuators included in the body massage module; lifting the user's left or right leg using the actuators included in the leg massage module; and massaging the user's lower limbs through the body massage module and / or leg massage module. Additionally, for action 523, an additional action 625 (or alternatively for action 527) can be performed to massage the user's lower limbs. To further enhance the skin care effect provided by the light irradiator 400, the control unit 120 can control the massage module 170 and / or airbag of the body massage unit 101 to bring the second body part (e.g., scalp) toward the light irradiator 400. In this case, the object controlled by the control unit 120 can be the actuator included in the body massage module 170 of the body massage unit.

[0398] Hereinafter, referring to Table 5, the actions of each step in the second care mode (e.g., scalp care mode) according to the second embodiment will be described in detail.

[0399] Table 5

[0400] Table 5 illustrates the actions of each component within the first, second, and third time intervals, which are preset time intervals. The first, second, and third intervals sequentially and continuously represent the passage of time. Referring to Table 5, in the preparation phase, when the user selects the second care mode, the light source of the light irradiator 400 can be automatically turned on. The automatically turned-on light source continues during the first, second, and third intervals, and can then be automatically turned off at the end of the third interval. For example, the light irradiator 400 can be set to automatically turn off 30 seconds after the automatically turned-on light source.

[0401] Referring to Table 5, the second interval can be divided into multiple stages, such as a first stage and a second stage. According to one embodiment, the second interval, including the first stage and the second stage, can also be executed repeatedly multiple times (e.g., on both sides).

[0402] Unlike the first care mode M1, where the distinction between the first, second, and third zones corresponds to the angle of the backrest 1011 of the body massage unit 101, the second care mode M2 ​​allows the distinction between the first, second, and third zones to be set independently of the angle of the backrest 1011. In the first zone of the second care mode M2, the backrest 1011 is approximately 100% tilted, and this 100% tilt can be maintained up to the second and third zones. In the second care mode M2, by setting the angle of the backrest 1011 to 100%, the user can receive scalp care in a more stable and comfortable position after fully lying down. Correspondingly, to maintain body balance, the leg angle can be raised to 50%.

[0403] Referring to [Table 5], in step 1 of the first section, the backrest 1011 can be tilted to 100% angle. Correspondingly, the leg rest 1031 can be raised to 50% angle. In step 2 of the first stage of the second section, the right shoulder is pushed using an airbag, causing the head to turn to the right, thereby allowing light to shine onto the left side of the scalp. When the head is turned to the right, the right foot angle can be raised to its maximum, and blood circulation is promoted through the massage of the leg airbags. In step 2 of the first stage of the second section, massage can be performed by the leg airbags on the raised instep and heel of the right leg, and in step 3 of the first stage of the second section, massage can be performed by the leg airbags on the raised calf of the right leg. The leg airbags can operate sequentially from the distal end (e.g., the foot) to the proximal end (e.g., the calf), thereby guiding blood flow to the scalp and more effectively promoting blood circulation. In step 4 of the second stage of the second section, the airbags propel the left shoulder, causing the head to turn to the left, allowing light to shine onto the right side of the scalp. While turning the head to the left, the left foot can be raised to its maximum angle, and the massage from the leg airbags promotes blood circulation. In step 4 of the second stage of the second section, massage can be performed using the leg airbags on the raised instep and heel of the left leg. In step 5 of the second stage of the second section, massage can be performed using the leg airbags on the raised calf of the left leg. The leg airbags can be operated sequentially from the distal end (e.g., the foot) to the proximal end (e.g., the calf), thereby guiding blood flow to the scalp and more effectively promoting blood circulation. In steps 2 to 5 of the first and second stages of the second section, the right leg and left leg can be lifted sequentially in the order of right leg → left leg (or, according to the embodiment, left leg → right leg). For example, when turning the head to the right, lifting the right leg helps maintain body balance (lifting the opposite leg would cause the body to twist, causing discomfort). In steps 2 to 5 of the first and second stages of the second section, the body can be stabilized by simultaneously activating both pelvic airbags to prevent overall body twisting. In step 6 of the third section, a concentrated massage of the neck and shoulders can be performed. Since the neck and shoulders are close to the scalp, blood circulation to the head can be improved. Additionally, relaxing tense muscles can help with scalp care by relieving headaches, fatigue, and stress. In step 6 of the third section, both legs can be lifted approximately 100%, and massage can be performed using the airbag on the side furthest from the heart (the foot side) to promote blood circulation from the lower body to the scalp. In the third zone, to maximize the effect of scalp care, excessive stretching should be avoided. Instead, both legs should be raised, and the focus should be on lower limb massage through the airbags.

[0404] According to one embodiment, starting from step 2 of stage 1 in the second interval, other massage actions described in [Table 5] can be assisted by activating the back airbag or a portion of the back airbag.

[0405] The actions described in Table 5 are shown in a simplified manner in Table 6 below.

[0406] Table 6

[0407] Referring to [Table 6], in the second care mode M2, at the beginning of the second care mode M2, to achieve maximum effect, the brightness intensity is irradiated at 100% for a predetermined time (e.g., during the first interval). After the predetermined time has elapsed (e.g., starting from the second interval), the brightness intensity can be reduced by 50% to improve user comfort. The angle of the backrest 1011 can be maintained at 100% at the beginning of the second care mode M2 ​​and during the operation of the second care mode. At the beginning of the second care mode M2, the leg rest 1031 is raised at a predetermined angle (e.g., approximately 50%) and held (e.g., held in the first interval). Then (e.g., in the second interval), the action of raising one leg to 100% is performed alternately, and this action is repeated as needed. Afterward, blood circulation to the scalp is induced by raising both legs. The massage module 170 can perform a full-body relaxation massage in the first interval, a massage targeting the back and buttocks in the second interval, and a massage targeting the neck and shoulders in the third interval. According to one embodiment, the total running time of the second care mode M2 ​​can be allocated to 30 minutes, but this can be modified according to the embodiment. For example, the running time of the second care mode M2 ​​can also be allocated to 40 minutes, but it is not limited to this. During the total movable time of the second care mode M2, the first interval, the second interval, and the third interval are executed sequentially. When the third interval ends, it can be repeatedly executed from the first interval. For example, the first interval with 100% light intensity is executed for five minutes, and the second and third intervals are also executed for five minutes each, with each interval performing two actions, so that the second care mode M2 ​​can be executed for a total of 30 minutes. According to one embodiment, the second care mode M2 ​​can be repeatedly executed or the time of the second care mode can be extended according to the user's input. When the time of the second care mode M2 ​​is extended, the time of a portion of each interval can be extended, or the total movable time of the second care mode M2 ​​can be extended. As mentioned above, the first care mode M1 provides massage while irradiating light to the first body part, and the second care mode M2 ​​provides massage while irradiating light to the second body part, but it is not limited to this. For example, all the actions of the first care mode M1 can be performed corresponding to the actions of the second body part. In other words, all actions in the first care mode M1 remain unchanged, except that the target area for light illumination is changed to a second body part. It is therefore reasonable that the second care mode M2 ​​can also perform actions corresponding to the first body part.

[0408] The action can be executed by the control unit 120. Alternatively, the action can be implemented and executed by the control unit 120 using instructions stored in the storage unit 130. According to different embodiments, one or more actions of the corresponding components described above may be omitted, or one or more other actions may be added. According to different embodiments, the actions can be executed sequentially, in parallel, repeatedly, or heuristically, or one or more of the actions can be executed in different orders, or omitted, or one or more other actions can be added.

[0409] According to the massage device and its control method, light therapy can be provided to a first body part (e.g., face) and a second body part (e.g., scalp) that is different from the first body part while massaging the body, and the skin (including face and scalp) can be improved without wearing an additional LED mask or using cosmetics.

[0410] The technical concept of this disclosure has been described above with reference to the accompanying drawings. However, this is merely an exemplary description of preferred embodiments of this disclosure and does not limit the scope of this disclosure. Furthermore, those skilled in the art should understand that various modifications and imitations can be made without departing from the technical concept of this disclosure.

[0411] Furthermore, the structure and function of the massage device described in this manual can be extended and applied to various (wearable) health care devices that provide health care functions (e.g., massage function, biosignal measurement function, etc.). Therefore, the term "massage device" in this manual can be replaced with "(wearable) health care device" for further explanation.
