Description

Technical Field

[0002] Hair removal devices and skin rejuvenation devices are common skin treatment devices used in daily life. When using a skin care device, the user holds the device with the working surface facing the skin, and then moves the device.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

For example, A and / or B can represent three cases: A exists alone, A and B exist simultaneously, and B exists alone. The symbol " / " in this document indicates that the related objects are in an "or" relationship; for example, A / B means A or B.

[0028] The term "multiple" in this application refers to two or more. Furthermore, it should be understood that the terms "first," "second," etc., used in the description of this application are used only for descriptive purposes and should not be construed as indicating or implying relative importance, nor as indicating or implying order.

[0029] In the description of the embodiments in this application, the words "exemplary" or "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0030] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2 A skin treatment device 100 provided in an embodiment of this application is shown.

[0031] In this application, the skin treatment device 100 is provided with a working surface 111. When a user uses the skin treatment device 100, the working surface 111 can be first placed over the skin that needs to be treated, and then the skin treatment device 100 can be moved. When the skin treatment device 100 is working, it can perform hair removal, skin rejuvenation, and other treatments on the skin covered by the working surface 111.

[0032] It is understood that the skin treatment device 100 can be a light-based skin treatment device (such as a hair removal device, skin rejuvenation device, etc.), an ultrasonic beauty device, an electrical stimulation beauty device, etc. This application does not specifically limit the method by which the skin treatment device 100 performs skin treatment.

[0033] For example, the skin treatment device 100 is a phototherapy skin treatment device, which can emit light through the working surface 111. The light shines on the skin covered by the working surface 111, enabling the skin treatment device 100 to treat the skin. The light emitted by the phototherapy skin treatment device can be, but is not limited to, intense pulsed light (IPL), laser, or visible light of different wavelengths.

[0034] For example, the skin treatment device 100 can be an ultrasonic beauty device, such as a micro-focused ultrasonic beauty device, which can emit ultrasonic waves (e.g., micro-focused ultrasonic waves) through the working surface 111. The ultrasonic waves are transmitted to the skin, which can realize the skin treatment device 100 to treat the skin.

[0035] For example, the skin treatment device 100 can be an electrical stimulation beauty device, which can apply electrical stimulation to the user's skin through the working surface 111, such as radio frequency current, medium frequency current and / or microcurrent (such as EMS current), and achieve beauty effects such as skin lifting and tightening through the current, so as to realize the skin care of the skin treatment device 100.

[0036] The following embodiments mainly illustrate the case where the skin treatment device 100 performs skin treatment by emitting light.

[0037] In this application, the width, length, and height directions of the skin treatment device 100 can be defined as a first direction, a second direction, and a third direction, respectively, and the first, second, and third directions are mutually perpendicular. For example, the first direction could be... Figure 1 and Figure 2 The X direction and its opposite direction are shown. The second direction can be... Figure 1 and Figure 2 The Y-direction and its opposite direction are shown. The third direction can be... Figure 1 and Figure 2 The Z direction and its opposite direction are shown.

[0038] The improvements in this application are mainly applied to the scenario where the skin treatment device 100 is moved on the skin surface by the user, and the skin treatment device 100 acts on the skin once every preset time or every preset distance of movement, that is, the application is a scenario of skin care while sliding, and for hair removal devices, it is the sliding mode.

[0039] It is understandable that when the working surface 111 covers the skin to be treated, the large friction surface between the working surface 111 and the skin to be treated makes it difficult for the user to operate the skin treatment device 100 to move on the skin surface, and it is also easy to cause discomfort to the skin due to friction, especially when the skin is warm or slightly sweaty, the resistance and discomfort are more obvious.

[0040] In related technologies, in order to improve this situation, it is proposed to add a rolling element to the working end of the skin treatment device 100. The rolling element is used to contact the skin and roll on the skin when the working surface 111 covers the skin. In this way, by adding the rolling element, the user's comfort in moving the skin treatment device 100 on the skin surface can be improved.

[0041] However, the addition of the rolling element brings another problem. Because of the reduced resistance, the movement speed of the skin treatment device 100 on the skin surface is usually determined by the force applied by the user. The force applied by the user is not easy to control. If the user applies too much force when operating the skin treatment device 100, the speed of moving the skin treatment device 100 will be faster. In this case, the treatment time of the skin to be treated covered by the working surface 111 will be shorter, which will affect the skin treatment effect. This effect will be greater for light skin treatment devices and ultrasonic beauty devices.

[0042] It should be further pointed out that for the skin treatment device 100 powered by an energy storage capacitor, if the user moves the skin treatment device 100 too quickly on the skin surface, it can lead to "missed skin treatments," such as missed light application. Specifically, when the user moves the skin treatment device on the skin surface, the skin treatment device 100 applies a treatment to the skin once for each preset distance or preset time, consuming the energy storage capacitor. The skin areas treated in adjacent treatments should be close, such as slightly overlapping, sequentially connected, or with a small interval. As the skin treatment device 100 moves from one skin treatment area to the next, it charges the energy storage capacitor. If the user moves the skin treatment device 100 too quickly on the skin surface, after moving the preset distance or preset time, the energy storage capacitor may not be charged to the required level, resulting in "missed skin treatments."

[0043] To address at least one of the above problems, this application proposes the following solution.

[0044] Please refer to the following: Figure 3 In one embodiment, the skin treatment device 100 includes a housing 10. The housing 10 is provided with a working end 11, and a working surface 111 is located on the working end 11. The working surface 111 is used to cover the skin, so that the skin treatment device 100 can perform skin treatment.

[0045] In one feasible embodiment, the skin treatment device 100 is a phototherapy skin treatment device, such as a hair removal device or a skin rejuvenation device. The skin treatment device 100 may include a light-emitting component 20, which may be located within the housing 10 and fixedly connected to the housing 10. The working surface 111 is provided with a light-emitting area 112, and the light-emitting component 20 can generate light that is emitted onto the skin through the light-emitting area 112. That is, when the working surface 111 covers the skin, the light-emitting component 20 generates light that is emitted onto the skin through the light-emitting area to achieve skin treatment.

[0046] Optionally, the skin treatment device 100 may include an energy storage capacitor 30, which may be located inside the housing 10 and fixedly connected to the housing 10. The energy storage capacitor 30 may be electrically connected to the light-emitting component 20 to supply power to the light-emitting component 20.

[0047] Optionally, the energy storage capacitor 30 can release electrical energy to the light-emitting component 20 after being fully charged or charged to a preset value, thereby powering the light-emitting component 20 to emit light once (e.g., a single pulse light) or emit light multiple times at a preset frequency (e.g., multiple sub-pulse light). After the light-emitting component 20 finishes emitting light, the energy storage capacitor 30 needs to be charged to prepare for the next time the light-emitting component 20 emits light.

[0048] It is understandable that the skin treatment device 100 can also be an ultrasonic beauty instrument, such as a micro-focused ultrasonic beauty instrument, with a micro-focused ultrasonic transducer installed inside the housing 10 to generate micro-focused ultrasonic waves that can be directed at the skin to be treated through the working surface 111.

[0049] Alternatively, the skin treatment device 100 can be an electrical stimulation beauty device with stimulation electrodes set at the working end 11. During operation, stimulation currents such as radio frequency current, intermediate frequency current and / or microcurrents (e.g., EMS current) can be generated through the stimulation electrodes to provide stimulation currents for user skin care.

[0050] It should be noted that the above-mentioned light-emitting components 20, micro-focused ultrasound transducers, stimulation electrodes, etc. can all be collectively referred to as the processing components of the skin treatment device 100, and the above-mentioned light, micro-focused ultrasound, stimulation current, etc. can all be collectively referred to as nursing energy.

[0051] Optionally, the housing 10 extends along a second direction to simplify the skin treatment device 100.

[0052] In this application, the position of the working end 11 on the housing 10 is not specifically limited. For example, as Figure 1 As shown, the working end 11 may protrude from one side of the housing 10 in the first direction. For example, the working end 11 may be provided on one side of the housing 10 in the second direction or the third direction, or extend from any side of the housing 10 to the adjacent side.

[0053] This application does not specifically limit the structure of the housing 10. For example, as Figure 1 As shown, the housing 10 defines a receiving space. The housing 10 may include an upper housing 12 and a lower housing 13 split along a third direction. The upper housing 12 and the lower housing 13 may be distributed in the third direction, and the lower housing 13 is located at the bottom of the upper housing 12. The upper housing 12 and the lower housing 13 are detachably connected.

[0054] The working end 11 may be partially formed on the upper shell 12 or the lower shell 13, or it may be partially formed by the cooperation of a part of the structure of the upper shell 12 and a part of the structure of the lower shell 13. The embodiments of this application do not limit this.

[0055] For example, the housing 10 may include a plurality of sections split along a first direction and / or a second direction, and the plurality of sections are detachably connected.

[0056] Optionally, the skin treatment device 100 may include an inner shell 14 disposed within the housing 10, and the light-emitting component 20 or the micro-focused ultrasound transducer may be fixedly connected to the inner shell 14.

[0057] Optionally, the inner shell 14 may cover the various components of the skin treatment device 100 and / or provide mounting positions for the various components, thereby protecting and / or installing the various components.

[0058] Please refer to the following: Figure 4 and Figure 5 Optionally, the skin treatment device 100 may further include a roller 40, which may be disposed at the working end 11. The roller 40 is used to contact and roll on the skin when the working surface 111 covers the skin. By adding the roller 40, the skin treatment device 100 can be guided to move on the user's skin surface, reducing frictional discomfort between the working surface 111 and the user's skin, thereby improving the user's comfort when operating the skin treatment device 100 on the skin surface.

[0059] Optionally, the scroll 40 may protrude from the working surface 111 to contact the user's skin.

[0060] It is understood that when a user uses the skin treatment device 100, the working surface 111 can face the skin, and the rolling element 40 can abut against the skin. When moving the skin treatment device 100, the working surface 111 can pass over the area of ​​the user's skin that needs to be treated. The treatment element of the skin treatment device 100 will generate care energy to care for the skin.

[0061] For example, in the case of a light-emitting skin treatment device, when the skin treatment device 100 is moved, the light-emitting component 20 can irradiate light onto the area covered by the working surface 111 during the movement of the skin treatment device 100, thereby achieving skin treatment.

[0062] Optionally, each time the light-emitting component 20 emits light, the energy storage capacitor 30 needs to complete a charging and discharging cycle. At least some components in the light-emitting component 20 are electronic devices that consume electrical energy to emit light.

[0063] This application does not specifically limit the composition of the light-emitting component 20. For example, the light-emitting component 20 may include a light-transmitting element, a light-emitting element, and a matching circuit electrically connected to the light-emitting element. The light-emitting element may be an electronic component that consumes electrical energy to emit light, such as a lamp tube, and the light-emitting element is electrically connected to the energy storage capacitor 30. The light-transmitting element may include a sapphire crystal. A light-emitting port may be opened on the working surface 111. The light-transmitting element may be partially housed in the light-emitting port and exposed on the working surface 111 for contact with the skin, forming a light-emitting area 112 on the housing 10. The light emitted by the light-emitting element can be transmitted through the light-transmitting element and then irradiate the user's skin.

[0064] The light-emitting area 112 can be formed on the working surface 111 to irradiate light onto the skin covered by the working surface 111.

[0065] The light-emitting component 20 may also include other components that work in conjunction with the light-emitting element and are used in conjunction with the installation of the light-emitting element and the light-transmitting element, which will not be described in detail here.

[0066] Optionally, the light-transmitting element can be provided at the working end 11, wherein part of the light-transmitting element can be installed on the inner shell 14 to fix the light-transmitting element; part of it is provided inside the light-emitting opening and exposed on the working surface 111 for contact with the skin.

[0067] Optionally, the skin treatment device 100 also includes a cooling element, such as a semiconductor cooling element. Optionally, the cooling element is attached to at least one side of the light-transmitting element for applying a cold compress to the light-transmitting element so that the light-transmitting element can be used to apply a cold compress to the skin to be treated.

[0068] It is understandable that the cooling element can also be configured in other ways, especially with other types of skin treatment devices 100, such as the cooling element facing the working surface 111 to cool the working surface 111. For example, for a light-treated skin device, the cooling element is located on the side of the light outlet; for an ultrasonic beauty device, the cooling element is located on the side of the ultrasonic outlet on the working surface 111.

[0069] It is understandable that the principle of the energy storage capacitor 30 releasing electrical energy after being charged, enabling the light-emitting component 20 to emit light, is a common principle in related fields and will not be elaborated here.

[0070] This application does not specifically limit the fixing method for fixed installation and fixed connection. For example, fixing methods may include, but are not limited to, mortise and tenon fixing, screw fixing, welding fixing, adhesive fixing, and integral molding fixing.

[0071] This application does not specifically limit the connection method of detachable connection. For example, the connection method of detachable connection may include, but is not limited to, snap-fit ​​connection, screw connection and sliding connection.

[0072] Please refer to the following: Figure 4 and Figure 5 Optionally, the skin treatment device 100 may also include a damping structure 50. The damping structure 50 may be disposed at the working end 11. The damping structure 50 may cooperate with the rolling element 40, and the damping structure 50 is used to change the damping force on the rolling element 40 when it rolls, so as to limit the rotational speed of the rolling element 40.

[0073] It should be noted that the damping structure 50 is used to change the damping force experienced by the rolling element 40 when it rolls, meaning that the damping force experienced by the rolling element 40 increases after the addition of the damping structure 50 compared to when the damping structure 50 is not set.

[0074] Thus, by increasing the damping structure 50 and through the cooperation between the damping structure 50 and the rolling element 40, the rolling resistance of the rolling element 40 when rolling on the skin surface can be increased, thereby limiting the rolling speed of the rolling element 40 on the skin surface, and thus limiting the movement speed of the skin treatment device 100 on the skin surface. In other words, the user needs to exert more force to make the skin treatment device 100 move faster on the skin surface. This prevents the skin treatment device 100 from moving too fast on the skin surface, allowing the skin treatment device 100 to have a longer treatment time in each area, so that the care energy emitted by the skin treatment device 100 can better act on the skin being treated, thereby ensuring or improving the skin treatment effect.

[0075] Thus, by providing a rolling element 40 at the working end 11, this application can guide the skin treatment device 100 to move on the user's skin surface, improving the frictional discomfort between the working surface 111 and the user's skin, thereby enhancing the user's comfort in operating the skin treatment device 100 on the skin surface. Furthermore, by providing a damping structure 50 that works in conjunction with the rolling element 40, the damping force experienced by the rolling element 40 during rolling can be changed, thereby limiting the movement speed of the rolling element 40 and the skin treatment device 100 on the skin surface. This can prevent the skin treatment device 100 from moving too fast on the skin surface, allowing the skin treatment device 100 to have a longer treatment time in each area to be treated, and enabling the nursing energy emitted by the skin treatment device 100 to better act on the skin to be treated, thus ensuring or improving the skin treatment effect.

[0076] The damping structure 50 can decelerate the rotation of the rolling element 40, thereby adjusting the rotational speed of the rolling element 40. Reducing the rotational speed of the rolling element 40 decreases its rolling speed on the user's skin, thus reducing the speed at which the skin treatment device 100 moves on the skin. This reduces the increase in speed when the working surface 111 passes through various parts of the skin, preventing insufficient treatment time for areas covered by the working surface 111, and improving the skin treatment effect of the skin treatment device 100.

[0077] In this application, the position of the rolling element 40 in the working end 11 is not specifically limited, as long as the rolling element 40 can contact the skin and roll on the skin when the working surface 111 covers the skin.

[0078] Optionally, such as Figure 5 As shown, a storage opening 113 can be provided on the working surface 111, and the rolling element 40 is rotatably disposed in the storage opening 113, and the rolling element 40 can protrude from the working surface 111 from the storage opening 113. In this way, by providing the storage opening 113, it is convenient to install the rolling element 40.

[0079] Optionally, the rolling element 40 can enter the working end 11 or protrude from the working surface 111 through the receiving port 113, in which case the damping structure 50 can be located inside the working end 11.

[0080] For example, the rolling element 40 may be located outside the working end 11; in this case, the damping structure 50 may be located at least partially outside the working end 11.

[0081] The damping force on the rolling element 40 can be calculated using the rolling speed and damping coefficient of the rolling element 40. The principle for calculating the damping force on a rolling component during rotation is a general principle in the relevant field and will not be elaborated here.

[0082] The following embodiments are mainly illustrated by taking the case where the rolling element 40 is rotatably disposed in the storage opening 113 and the damping structure 50 is located in the working end 11.

[0083] Optionally, the damping structure 50 can change the damping force experienced by the rolling element 40 during rolling by means of mating, magnetic mating, or viscous fluid speed limiting.

[0084] Optionally, the damping structure 50 and the rolling element 40 may have one or more mating relationships. For example, the damping structure 50 may have both abutting and magnetic mating relationships.

[0085] Optionally, the damping structure 50 and the rolling element 40 can be configured to have only one cooperative state, that is, the damping force applied by the damping structure 50 to the rolling element 40 remains unchanged.

[0086] Optionally, the damping structure 50 and the rolling element 40 can have at least two engagement states. Under different engagement states, the damping structure 50 is used to make the damping force on the rolling element 40 different, so as to limit the rolling element 40 to different rotational speed levels.

[0087] The rotational speed level is used to characterize the ease with which the rolling element 40 rolls on the skin surface. When the damping force on the rolling element 40 is large, it is more difficult for the rolling element 40 to roll, requiring the user to apply greater force to drive it. In other words, the rolling element 40 is easily confined to a lower rotational speed range when rolling on the skin surface, thus allowing the skin treatment device 100 to move within a lower speed range on the skin surface. When the damping force on the rolling element 40 is small, it rolls more easily, requiring less force from the user to drive it. In other words, the rolling element 40 can be confined to a higher rotational speed range when rolling on the skin surface, allowing the skin treatment device 100 to move within a higher speed range on the skin surface.

[0088] In this way, users can choose to make the damping structure 50 and the rolling element 40 work in different states according to their needs, so as to meet different movement scenarios, different skin conditions, or different usage habits.

[0089] Optionally, the damping structure 50 may include a damping element 51, which may abut against the rolling element 40 to change the damping force on the rolling element 40 by changing the friction force on the rolling element 40, thereby limiting the rotational speed of the rolling element 40.

[0090] It is understandable that when the damping structure 50 is not provided, the frictional force experienced by the rolling element 40 is relatively small, typically only due to installation friction during the mounting of the rolling element 40. With the damping element 51 provided, the frictional force experienced by the rolling element 40 during rolling is increased through the abutting engagement between the damping element 51 and the rolling element 40, thereby limiting the rotational speed of the rolling element 40. Furthermore, increasing the damping force on the rolling element 40 through this abutting engagement simplifies the design and saves costs.

[0091] It should be noted that for the damping structure 50 with damping element 51, the engagement state is the abutting engagement state. It can be understood that different abutting engagement states result in different abutting forces between damping element 51 and rolling element 40, thus causing different damping forces on rolling element 40.

[0092] In some cases, the damping element 51 can directly and rigidly abut against the rolling element 40. When the rolling element 40 rotates, it can generate direct friction with the damping element 51, so that the damping element 51 can limit the rotation speed of the rolling element 40 through the frictional force of direct friction with the rolling element 40, reduce the speed at which the rolling element 40 rolls on the user's skin, and thus slow down the speed at which the user moves the skin treatment device 100 when using it.

[0093] In other cases, the damping element 51 can indirectly contact the rolling element 40 through a buffer (not shown), thereby achieving the contact engagement between the damping element 51 and the rolling element 40.

[0094] The buffer member has two sides that can abut against the rolling member 40 and the damping member 51, respectively. The buffer member can undergo elastic deformation under the pressure of the damping member 51 and the rolling member 40. After elastic deformation, the thickness of the buffer member decreases, while the contact area with the damping member 51 and the rolling member 40 increases. When the rolling member 40 rotates, it can rub against the buffer member, thereby indirectly rubbing against the damping member 51. This allows the damping member 51 to limit the rotational speed of the rolling member 40 through indirect friction with it, i.e., the frictional force between the buffer member and the rolling member 40, thus reducing the speed at which the rolling member 40 rolls on the user's skin. This slows down the user's movement of the skin treatment device 100.

[0095] This application does not specifically limit the material of the cushioning component. For example, the material of the cushioning component can be, but is not limited to, rubber or silicone.

[0096] The following uses a light skin treatment device as an example to further illustrate the effect of this application. It can be understood that each time the light-emitting component 20 emits light to illuminate the user's skin, the location can be defined as a lighting area. Ideally, two adjacent lighting areas should be similar, such as having a small overlap, being sequentially connected, or having a small interval.

[0097] Since the frequency of light emitted by the light-emitting component 20 is limited by the charging time of the energy storage capacitor 30, the light-emitting component 20 can only emit light after the energy storage capacitor 30 has finished charging.

[0098] Therefore, for a skin treatment device 100 with only a rolling element 40, when a user uses the skin treatment device 100, the guiding effect of the rolling element 40 may cause the user to move the skin treatment device 100 too fast. As a result, when the skin treatment device 100 moves to the next ideal lighting area, the energy storage capacitor 30 may not be fully charged or meet the power supply requirements, and therefore the device may not be able to provide light in that ideal lighting area. This will reduce the number of actual lighting areas on the skin area traversed by the working surface 111, thus affecting the skin treatment effect.

[0099] In the skin treatment device 100 proposed in this application, because a damping structure 50 is added, the damping structure 50 can increase the rotational friction of the rolling element 40 through friction with the rolling element 40, thereby effectively preventing the rolling element 40 from rotating too fast, and thus effectively preventing the skin treatment device 100 from moving too fast on the skin surface. This can ensure or increase the number and density of the actual lighting area in the area traversed by the working surface 111, avoid missed lighting, and thus improve the skin treatment effect of the skin treatment device 100 on the skin.

[0100] Optionally, the rolling element 40 is rotatably pressed against the damping element 51 and the inner wall of the working end 11. In this way, the damping element 51 and the rolling element 40 can be engaged in abutment.

[0101] Please refer to the following: Figure 6 Optionally, the rolling element 40 may include two rotating shafts 41 and an abutment roller 42. The two rotating shafts 41 are respectively located at both ends of the abutment roller 42 in the axial direction, and are both fixedly connected to the abutment roller 42.

[0102] Optionally, the diameters of both rotating shafts 41 are smaller than the diameter of the abutment roller 42. The abutment roller 42 can be located in the receiving opening 113 and protrude from the working surface 111 through the receiving opening 113. The portion of the outer periphery of the abutment roller 42 outside the receiving opening 113 can come into contact with the user's skin. The two rotating shafts 41 can be hidden on the inner side of the housing 10 at the working end 11.

[0103] For example, such as Figure 5 and Figure 6 As shown, the receiving port 113 can be opened along the first direction, and the axial directions of the rotating shaft 41 and the abutting roller 42 can coincide with the second direction.

[0104] Please refer to the following: Figure 7 Two first receiving grooves 511 can be opened on the side of the damping member 51 facing the rolling member 40. The two first receiving grooves 511 are spaced apart. The abutting roller 42 is located between the first receiving grooves 511. The two first receiving grooves 511 can respectively receive two rotating shafts 41, and the outer periphery of each rotating shaft 41 can protrude from the corresponding first receiving groove 511.

[0105] The damping element 51 can achieve abutment with the rolling element 40 through the abutment engagement between the inner wall of the first receiving groove 511 and the rotating shaft 41. Specifically, the rotating shaft 41 rotates and abuts between the inner wall of the first receiving groove 511 and the inner wall of the working end 11.

[0106] Optionally, two second storage slots 15 can be provided on the inner side of the working end 11, and the two second storage slots 15 can correspond one-to-one with the two first storage slots 511. Each second storage slot 15 can accommodate the part of the corresponding rotating shaft 41 that protrudes from the first storage slot 511.

[0107] The rotating shaft 41 can rotate within the corresponding first storage groove 511 and the corresponding second storage groove 15, and the rotating shaft 41 can abut against the damping structure 50 by abutting against the inner wall of the first storage groove 511.

[0108] It is understandable that the inner wall of the first storage groove 511 can directly abut against the outer periphery of the rotating shaft 41, and the damping structure 50 reduces the rotation speed of the rotating shaft 41 through the frictional force of direct friction with the rotating shaft 41.

[0109] Alternatively, a buffer element can be fixedly connected to the inner wall of the first storage groove 511. The buffer element can abut against the outer periphery of the rotating shaft 41, thereby achieving the abutment between the damping structure 50 and the rotating shaft 41. The damping structure 50 reduces the rotation speed of the rotating shaft 41 through the frictional force of indirect friction with the rotating shaft 41.

[0110] Similarly, the inner wall of the second storage groove 15 can reduce the speed of the rotating shaft 41 through frictional force from direct friction with the rotating shaft 41, or the inner wall of the second storage groove 15 can be fixedly connected with a buffer, and the inner wall of the second storage groove 15 can reduce the speed of the rotating shaft 41 through frictional force from indirect friction with the rotating shaft 41. The embodiments of this application do not limit this.

[0111] In some cases, both rotating shafts 41 are coaxially arranged with the abutment roller 42, and the distance from which the abutment roller 42 protrudes from the receiving port 113 remains constant when the rolling element 40 rotates.

[0112] In other cases, the two rotating shafts 41 can be eccentrically arranged with respect to the abutment roller 42, and the two rotating shafts 41 can be coaxially arranged. The distance by which the abutment roller 42 protrudes from the receiving port 113 changes with the rotation of the rolling element 40, realizing periodic radial jumping, which can provide vibration feedback when the rolling element 40 rolls on the user's skin. The embodiments of this application are not limited in this respect.

[0113] It is understandable that the rotating shaft 41 and the abutting roller 42 can be integrally formed.

[0114] Optionally, the rotating shaft 41 and the abutment roller 42 are made of the same material.

[0115] Optionally, the material of the shaft 41 can be a material with high wear resistance and high self-lubrication, that is, the shaft 41 is a wear-resistant part and a part with high self-lubrication.

[0116] This application does not specifically limit the material of the rolling element 40. For example, the material of the rolling element 40 can be, but is not limited to, polyformaldehyde (POM). Polyformaldehyde is a hard and dense material with a smooth, glossy surface. Its wear resistance and self-lubricating properties are superior to most engineering plastics, and it also has good oil resistance and peroxide resistance.

[0117] In some cases, the peripheral wall of the abutment roller 42 can come into direct contact with the user's skin.

[0118] In other cases, the peripheral wall of the abutment roller 42 may be covered with a soft layer (not shown), which can come into contact with the user's skin to achieve contact between the abutment roller 42 and the skin. This increases the friction with the skin and achieves an anti-slip effect. The embodiments of this application do not limit this.

[0119] This application does not specifically limit the material of the soft padding layer. For example, the material of the soft padding layer can be, but is not limited to, rubber pads or silicone pads.

[0120] Optionally, the damping member 51 is movably disposed on the working end 11 in the direction of approaching or away from the rolling member 40, so that there are at least two abutting engagement states between the damping member 51 and the rolling member 40; in different abutting engagement states, the abutting force between the damping member 51 and the rolling member 40 is different, resulting in different rolling friction between the damping member 51 and the rolling member 40, so that the damping force on the rolling member is different, so that the damping structure 50 restricts the rolling member 40 to different rotational speed levels.

[0121] It is understood that by making the damping member 51 movably disposed on the working end 11 in the direction of approaching or moving away from the rolling member 40, the abutting force between the damping member 51 and the rolling member 40 can be adjusted, thereby enabling the damping member 51 and the rolling member 40 to have at least two abutting engagement states.

[0122] like Figure 5 and Figure 6 As shown, the damping member 51 can move towards or away from the receiving port 113. When the damping structure 50 is close to the receiving port 113, it can increase the contact force between the damping member 51 and the rolling member 40, thereby increasing the friction between the damping member 51 and the rolling member 40, thereby increasing the damping force on the rolling member 40, thereby improving the limiting effect on the rolling member 40, so as to keep the rolling member 40 at a lower rotational speed level.

[0123] When the damping structure 50 is far away from the receiving port 113, the contact force between the damping element 51 and the rolling element 40 can be reduced, thereby reducing the friction between the damping element 51 and the rolling element 40, thereby reducing the damping force on the rolling element 40, thereby reducing the restrictive effect on the rolling element 40, so as to allow the rolling element 40 to be at a higher rotational speed level.

[0124] It can be understood that when the damping structure 50 limits the rotational speed of the rolling element 40 through friction generated by the abutting fit, the corresponding engagement state can be the abutting fit state. By changing the distance between the damping element 51 and the rolling element 40 and the pressure applied by the damping element 51 to the rolling element 40, the rolling friction between the rolling element 40 and the damping element 51 can be adjusted, thereby placing the rolling element 40 in different abutting fit states; when the rolling element 40 is in different abutting fit states, the rolling element 40 is at different rotational speed levels.

[0125] In this application, the engagement state includes at least a first engagement state and a second engagement state. The skin treatment device 100 may have a face treatment mode and a limb treatment mode. The first engagement state corresponds to the face treatment mode, and the second engagement state corresponds to the limb treatment mode. In the first engagement state, the damping force on the rolling element 40 is less than the damping force on the rolling element 40 in the second engagement state.

[0126] In other words, the rolling element 40 experiences less damping force in the first engagement state, which can be used in facial treatment mode. This makes it suitable for situations where the face is delicate and has low tolerance, thereby improving the comfort of facial care.

[0127] The rolling element 40 experiences a larger damping force in the second engagement state, which can be used in the limb treatment mode. This is suitable for situations where the limbs are relatively rough and have high tolerance, thereby improving the comfort of limb care.

[0128] It is understandable that when the skin processing device 100 is in face processing mode, the scroll member 40 can scroll more smoothly on the skin compared to when the skin processing device 100 is in limb processing mode.

[0129] It is understandable that since the skin on the human face is more susceptible to damage and has lower tolerance than the skin on the limbs, in order to reduce slippage of the scrolling element 40 when it rolls over the skin of the human face, and to reduce the situation where the user needs to increase the pressure applied to the skin treatment device 100 due to excessive damping force on the scrolling element 40, the damping force on the scrolling element 40 can be reduced when the skin treatment device 100 is in the face treatment mode, and is less than the damping force when the skin treatment device 100 is in the limb treatment mode, so as to reduce the risk of damage to the user's facial skin by the scrolling element 40.

[0130] It is understood that when the damping element 51 and the rolling element 40 are in contact, the contact state between the damping element 51 and the rolling element 40 can include at least the first contact state and the second contact state; when there are other contact relationships between the damping structure 50 and the rolling element 40, the contact state corresponding to the other contact relationships also includes at least the first contact state and the second contact state.

[0131] Optionally, the damping member 51 may include a main body 512 and an extension 513, the extension 513 being disposed at one end of the main body 512 toward the abutting roller 42, and the extension 513 being bent and extended toward one side of the main body 512.

[0132] Optionally, the extension direction of the extension 513 is set at an angle to the movable direction of the main body 512, such as perpendicular or approximately perpendicular, so that the extension 513 extends toward one side of the main body 512.

[0133] Optionally, two extensions 513 are provided, and the two extensions 513 are spaced apart.

[0134] Optionally, the abutting roller 42 is disposed between the two extensions 513, and the rotating shaft 41 rotates and abuts against the inner wall between the extension 513 and the working end 11.

[0135] In this way, the portion of the abutment roller 42 located inside the working end 11 can be housed between the two extensions 513, and the rotating shaft 41 can be rotatably abutted between the extension 513 and the inner wall of the working end 11, thereby saving internal space of the working end 11 and achieving a miniaturized design.

[0136] Furthermore, the extension 513 extends toward the side of the main body 512, which facilitates the rotation of the shaft 41 to abut against the inner wall of the extension 513 and the working end 11, and also facilitates the extension 513 to undergo a weak elastic deformation when abutting, so as to apply abutting force.

[0137] Optionally, the main body is movably disposed within the working end, the main body is spaced apart from the rolling element, and the extension is disposed on the side of the main body facing the rolling element.

[0138] Optionally, the main body 512 can be movably connected to the working end 11 in a direction close to or away from the rolling element 40. This allows the extension 513 to move in a direction close to or away from the rolling element 40, so that the damping force on the rolling element 40 can be adjusted, so that there are at least two abutting engagement states between the damping element 51 and the rolling element 40.

[0139] Optionally, the first receiving groove 511 described above is provided on the side of the extension 513 facing the rolling element 40 to receive one rotating shaft 41, so that the two extensions 513 can receive and abut against the two rotating shafts 41. Each extension 513 can abut against the rotating shaft 41 through the abutting engagement between the inner wall of the first receiving groove 511 and the rotating shaft 41.

[0140] Optionally, the distance between the two extensions 513 may be greater than the length of the abutment roller 42, and the abutment roller 42 may be located between the two extensions 513.

[0141] Optionally, the main body 512 is generally plate-shaped, and the extension 513 extends toward one side of the main body 512 facing the plate surface, so as to form the first storage groove 511.

[0142] Optionally, the working end 11 is provided with a guide groove 16 and a slot 17. Both the guide groove 16 and the slot 17 can connect the inner and outer sides of the housing 10, that is, the guide groove 16 and the slot 17 pass through the working end 11.

[0143] The guide groove 16 can extend in a direction close to or away from the rolling element 40, and the slot 17 can be formed on the side wall of the guide groove 16.

[0144] Optionally, the damping structure 50 may further include an adjusting part 52, which is fixedly mounted on the damping member 51. The adjusting part 52 is slidably disposed within the guide groove 16 and protrudes from the guide groove 16, meaning that the adjusting part 52 can pass through the guide groove 16 and protrude from the working end 11 through the guide groove 16. The adjusting part 52 is slidably connected to the guide groove 16, and the adjusting part 52 can drive the damping member 51 to move synchronously by sliding in the guide groove 16. In this way, the damping member 51 can be driven to move towards or away from the rolling member 40 by the adjusting part 52.

[0145] The slot 17 can accommodate the adjustment part 52, which is used to enter the slot 17 to adjust the engagement state between the damping member 51 and the rolling member 40.

[0146] The adjusting part 52 can enter the slot 17 through the guide groove 16, so that the inner wall of the slot 17 restricts the movement of the adjusting part 52 in the direction of approaching or away from the rolling element 40, thereby restricting the movement of the damping element 51 in the direction of approaching or away from the rolling element 40, so that the damping element 51 remains in contact with the two rotating shafts 41.

[0147] Optionally, the user can manually push the adjustment part 52 to move it, causing the adjustment part 52 to slide within the guide groove 16 and engage with the adjustment part 52 in the slot 17. Optionally, the adjustment part 52 can be disposed on one side of the main body 512.

[0148] Optionally, the adjustment part 52 may protrude from another plate surface of the main body part 512.

[0149] Optionally, the extending direction of the adjusting portion 52 is set at an angle to the direction approaching or away from the rolling element 40. In this application, the extending direction and sliding direction of the adjusting portion 52, as well as the extending direction of the extending portion 513, are not specifically limited. For example, as... Figure 4 and Figure 5 As shown, the direction closer to or further away from the rolling element 40 can coincide with the first direction, meaning the damping element 51 and the adjusting part 52 can move in the first direction. The receiving port 113 can be opened along the first direction. The adjusting part 52 can extend along a third direction, and the guide groove 16 can be opened on the side of the working end 11 in the third direction. The adjusting part 52 is slidably connected to the guide groove 16 along the first direction. The slot 17 can be located on the side wall of the guide groove 16 in the second direction.

[0150] Two extensions 513 may be located on the side of the main body 512 near the rolling element 40 and extend in a third direction. The two extensions 513 may protrude from the bottom of the main body 512. The two extensions 513 may be spaced apart in a second direction. Each extension 513 has a first receiving groove 511 on the side facing the corresponding rotating shaft 41 in the first direction, and the corresponding rotating shaft 41 is received through the first receiving groove 511.

[0151] In some cases, there may be only one slot 17, and in the first direction, the inner wall of the guide groove 16 away from the receiving opening 113 is spaced apart from the slot 17. When the adjusting part 52 is located in the guide groove 16, the adjusting part 52 can abut against the inner wall of the guide groove 16 away from the receiving opening 113 in the direction close to or away from the rolling member 40 (e.g., the first direction). At this time, the damping member 51 can maintain friction with the rolling member 40 to slow down the rotation speed of the rolling member 40.

[0152] When the adjustment part 52 can slide within the guide groove 16, the rolling element 40 and the damping element 51 can be in a first engagement state, that is, the skin treatment device 100 can be in the facial treatment mode.

[0153] When the adjustment part 52 moves in the direction close to the storage port 113 and engages with the slot 17, the damping structure 50 and the storage port...

[0154] The shortening of the spacing 113 increases the pressure applied by the damping structure 50 to the rolling element 40, thereby increasing the friction between the damping structure 50 and the rolling element 40, further slowing down the rotation speed of the rolling element 40. At this time, the rolling element 40 and the damping element 51 can be in a second engagement state, that is, the skin treatment device 100 can be in the limb treatment mode.

[0155] In other cases, there may be multiple slots 17, which are spaced apart in a direction close to or away from the rolling element 40 (e.g., a first direction). The adjusting part 52 can be engaged in each slot 17 to limit the movement of the damping element 51 and maintain the friction between the damping element 51 and the rolling element 40.

[0156] The adjusting part 52 can be adjusted to engage with a slot 17 closer to the receiving opening 113 to increase the friction between the damping member 51 and the rolling member 40, thereby slowing down the rotation speed of the rolling member 40. The embodiments of this application are not limited in this respect; the accompanying drawings and subsequent embodiments are illustrated by examples based on the presence of multiple slots 17.

[0157] For example, such as Figure 5 As shown, there can be three slots 17, which can be arranged in descending order of distance from the working surface 111 as the first, second, and third slots 17. When the adjustment part 52 is located in the first slot 17, the rolling element 40 and the damping element 51 can be in a first engagement state, that is, the skin treatment device 100 can be in the face treatment mode. When the adjustment part 52 is located in the third slot 17, the rolling element 40 and the damping element 51 can be in a second engagement state, that is, the skin treatment device 100 can be in the limb treatment mode.

[0158] When the adjustment part 52 is located in the second slot 17, the rolling element 40 and the damping element 51 can be in the first engagement state or the second engagement state, that is, the skin treatment device 100 can be in the face treatment mode or the limb treatment mode.

[0159] It is understood that the adjustment unit 52 can adjust and maintain the rolling friction between the damping member 51 and the rolling member 40 by engaging with the slot 17, so that the rolling friction between the damping member 51 and the rolling member 40 and the damping force on the rolling member 40 can be switched between multiple gears, and the rolling member 40 and the damping member 51 can switch between multiple contact states and the skin treatment device 100 can switch between multiple treatment modes, so that the rolling member 40 can reach different rotation speed levels.

[0160] Users can adjust the speed of the rolling element 40 by moving the adjustment unit 52 to change the contact state between the rolling element 40 and the damping element 51 according to their usage needs, and then use the skin treatment device 100. This improves the convenience for users to adjust the speed of the rolling element 40, and users can adjust the adjustment unit 52 to a suitable level according to their personal needs and habits to adjust the deceleration effect to a suitable level, thereby improving the user experience.

[0161] It is understandable that when users or staff clean, disinfect or repair the skin treatment device 100, the adjustment part 52 can be moved out of the slot 17 so that the adjustment part 52 can move within the guide slot 16, which facilitates the operation of users or staff.

[0162] It is understood that the number of adjusting parts 52 can be the same as the number of guide grooves 16. This application does not specifically limit the number of adjusting parts 52 and guide grooves 16. For example, one adjusting part 52 is provided.

[0163] In some cases, the adjustment part 52 can be fixedly connected to the damping member 51, which can be movably connected to the working end 11 in the extension direction (e.g., the second direction) of the slot 17. When the adjustment part 52 moves along the extension direction of the slot 17 to engage or disengage from the slot 17, the damping member 51 can move synchronously.

[0164] The two extensions 513 are spaced in the same direction as the extension of the slot 17. The distance between the two extensions 513 can be greater than the length of the abutment roller 42. When the damping member 51 moves in the extension direction of the slot 17, the side wall of the receiving port 113 can block the movement of the rolling member 40, so that the damping member 51 and the rolling member 40 move relative to each other in the extension direction of the slot 17.

[0165] In other cases, the adjusting part 52 is movably connected to the damping member 51 in the extending direction (e.g., the second direction) of the slot 17, and the damping member 51 is fixed relative to the working end 11 in the extending direction of the slot 17. When the adjusting part 52 slides in the guide groove 16, the damping member 51 moves synchronously in the same direction; when the adjusting part 52 moves along the extending direction of the slot 17 to engage or disengage from the slot 17, the adjusting part 52 can move relative to the damping member 51. The embodiments of this application do not limit this.

[0166] It is understandable that a movable connection can be achieved through linear moving connection structures such as slide rails and slide grooves, which allows two components to move relatively linearly.

[0167] Optionally, a guide surface may be provided on the outer periphery of the adjusting part 52. The guide surface may be an arc surface or a slope surface. The guide surface may abut against and slide against the inner wall of the guide groove 16 and / or the slot 17.

[0168] It is understood that when the adjustment part 52 enters the slot 17 from the guide groove 16, the guide surface can slide relative to the inner wall of the guide groove 16 and / or the slot 17, thereby guiding the adjustment part 52 to turn during the movement so as to enter the slot 17 opened on the side wall of the guide groove 16 from the guide groove 16.

[0169] When the adjusting part 52 enters the guide groove 16 from the slot 17, the guiding surface can slide relative to the inner wall of the guide groove 16 and / or the slot 17, thereby guiding the adjusting part to turn during the movement and enter the guide groove 16 from the slot 17.

[0170] In this way, the adjustment part 52, which moves in a straight line, can be guided by the curved or inclined surface to turn, thereby reducing the resistance when the adjustment part 52 enters the slot 17 or guide groove 16, and improving the smoothness and convenience of the adjustment part 52 moving in the guide groove 16 and entering the slot 17.

[0171] Optionally, the extension 513 may undergo elastic deformation.

[0172] Optionally, the damping structure 50 may further include an elastic element 53. The elastic element 53 is disposed between the damping element 51 and the working end 11. The elastic element 53 is in an elastic deformation state, and the elastic element 53 is used to drive the damping element 51 to abut against the rolling element 40 through the force generated by the elastic deformation. The elastic deformation state includes a compression state and a tension state, both of which can achieve the abutment between the damping element 51 and the rolling element 40.

[0173] Optionally, a blocking member 18 is provided inside the working end 11. The blocking member 18 can be fixed relative to the working end 11 and is spaced apart from the main body 512 in the direction close to or away from the rolling member 40.

[0174] Optionally, the elastic element 53 can be disposed between the main body 512 and the blocking element 18. The elastic element 53 can abut or be fixedly connected to the main body 512, and can abut or be fixedly connected to the blocking element 18 which is relatively fixed to the working end 11, thereby realizing the arrangement between the damping element 51 and the working end 11. The rolling element 40 can abut against the side of the extension 513 away from the blocking element 18. The elastic element 53 can undergo elastic deformation (i.e., compressed state) after the main body 512 and the blocking element 18 are squeezed, and the elastic force generated by the elastic deformation drives the damping element 51 to move or generate a moving tendency in the direction close to the receiving opening 113. The elastic force of the elastic element 53 can be applied to the rolling element 40 through the damping element 51, thereby increasing the friction between the rolling element 40 and the damping element 51, increasing the damping force on the rolling element 40, and adjusting the rotational speed level of the rolling element 40.

[0175] Optionally, the rolling element 40 can abut against the side of the extension 513 facing the blocking element 18. The elastic element 53 can undergo elastic deformation (i.e., stretched state) after the main body 512 and the blocking element 18 are stretched, and the elastic force generated by the elastic deformation drives the damping element 51 to move in the direction away from the receiving opening 113 or generate a moving tendency. The elastic force of the elastic element 53 can be applied to the rolling element 40 through the damping element 51, thereby increasing the friction between the rolling element 40 and the damping element 51, increasing the damping force on the rolling element 40, and adjusting the rotational speed level of the rolling element 40.

[0176] It is understood that the blocking member 18 can be fixedly connected to the upper shell 12, the lower shell 13 or the inner shell 14, and the embodiments of this application do not limit this.

[0177] It is understood that when a user uses the skin treatment device 100, the roller 40 rolls on the skin, and the skin can apply pressure to the roller 40. The pressure can be transmitted through the roller 40 to the damping member 51, causing the damping member 51 to move 113 relative to the receiving port or to have a tendency to move. At this time, the elastic member 53 can support the damping member 51 with its elasticity and increase the damping force on the roller 40 through its elasticity, so as to slow down the rolling speed of the roller 40 on the skin, increase the number and density of the light-reflecting areas in the area traversed by the working surface 111, and improve the effect of skin treatment.

[0178] In this application, the type of elastic element 53 is not specifically limited. For example, elastic element 53 can be, but is not limited to, a spring, tension spring, silicone pad, or rubber pad.

[0179] Please refer to the following: Figure 8 Optionally, a clearance groove 5121 may be provided on the side of the main body 512 away from the storage opening 113. The elastic member 53 can be stored in the clearance groove 5121.

[0180] Optionally, the damping structure 50 may also include a guide rod 54, and the elastic element 53 may be a spring or a tension spring, and the elastic element 53 may be sleeved on the outside of the guide rod 54.

[0181] Optionally, the guide rod 54 is located within the clearance groove 5121, and the guide rod 54 is fixedly connected to the side wall of the clearance groove 5121 in the direction close to the rolling element 40. The guide rod 54 can extend in the direction close to or away from the rolling element 40. The elastic element 53 can be a spring or a tension spring, and the elastic element 53 can be sleeved on the outside of the guide rod 54.

[0182] When the elastic element 53 deforms, the guide rod 54 can block the inner side of the elastic element 53, and the side wall of the clearance groove 5121 can block the outer side of the elastic element 53. The guide rod 54 and the clearance groove 5121 can limit the swaying of the elastic element 53 during the elastic deformation process, so as to improve the stability of the movement of the damping element 51.

[0183] The following embodiments mainly use the case where the elastic element 53 is a spring as an example for illustration.

[0184] In this application, the number of elastic elements 53 is not specifically limited. When there are multiple elastic elements 53, they can be spaced apart in a direction perpendicular to the direction of approaching or moving away from the rolling element 40. When there are multiple elastic elements 53, there can be multiple guide rods 54, and each guide rod 54 passes through a corresponding elastic element 53; there can be one or more clearance grooves 5121, and each clearance groove 5121 can accommodate at least one elastic element 53 and one guide rod 54.

[0185] It is understood that the damping element 51 and the guide rod 54 can be integrally formed. This application does not specifically limit the material of the damping element 51 and the guide rod 54. For example, the material of the damping element 51 and the guide rod 54 can be, but is not limited to, POM material.

[0186] It is understood that the damping structure 50 may include some or all of the elastic element 53, guide rod 54 and adjustment part 52. The following are examples of three cases of the damping structure 50.

[0187] In the first case, the damping member 51 can be connected to or abut against the elastic member 53 while having the adjusting part 52, and a guide rod 54 passing through the elastic member 53 is provided. When the adjusting part 52 is located in the guide groove 16, when the skin abuts against the rolling member 40, the skin can apply pressure to the rolling member 40, and the pressure can be transmitted to the damping member 51, causing the damping member 51 to cooperate with the blocking member 18 to squeeze the elastic member 53, and causing the adjusting part 52 to move in the guide groove 16; the elastic member 53 can increase the pressure of the damping member 51 on the rolling member 40 through its elasticity, thereby increasing the friction between the damping member 51 and the rolling member 40, and improving the deceleration effect on the rotation of the rolling member 40.

[0188] The user can also move the adjustment part 52 to engage the adjustment part 52 into the slot 17, thereby fixing the damping member 51 relative to the housing 10 in the direction close to or away from the rolling member 40 and maintaining friction with the rolling member 40; when the adjustment part 52 moves in the direction away from the rolling member 40, the damping member 51 can move synchronously, causing the elastic member 53 to compress.

[0189] In the second case, an adjustment part 52 can be provided on the damping member 51, while the damping structure 50 does not include the elastic member 53 and the guide rod 54. The user can insert the adjustment part 52 into each slot 17 to adjust the deceleration effect on the rolling member 40 to a suitable level according to personal usage habits, that is, to adjust the cooperation state between the rolling member 40 and the damping member 51 to a suitable cooperation state.

[0190] In the third case, the damping member 51 may not have an adjustment part 52, but may be connected to or abut against the elastic member 53, and a guide rod 54 may be provided, with the elastic member 53 sleeved on the outside of the guide rod 54. If the skin abuts against the rolling member 40, the elastic member 53 undergoes elastic deformation after being squeezed by the blocking member 18 and the damping member 51, and the elastic force generated by the elastic deformation increases the pressure of the damping member 51 on the rolling member 40, thereby increasing the friction between the damping member 51 and the rolling member 40, increasing the damping force on the rolling member 40, and improving the deceleration effect on the rotation of the rolling member 40. Optionally, the adjustment of the cooperation state between the damping member 51 and the rolling member 40 can be achieved by changing the distance between the damping member 51 and the working surface 111. When the distance between the damping element 51 and the working surface 111 is less than the preset distance threshold, the cooperation state between the damping element 51 and the rolling element 40 is the first cooperation state, and the skin treatment device 100 is in the face treatment mode; when the distance between the damping element 51 and the working surface 111 reaches the preset distance threshold, the cooperation state between the damping element 51 and the rolling element 40 is the second cooperation state, and the skin treatment device 100 is in the limb treatment mode.

[0191] In this application, no specific limit is made on the value of the spacing threshold, and the value of the spacing threshold can be determined according to the size of the skin treatment device 100 and its various components.

[0192] Optionally, the skin treatment device 100 may also include a detection component 60 and a control unit 70.

[0193] The detection component 60 is used to detect the rotation angle of the rolling element 40.

[0194] The control unit 70 may be located inside the housing 10, and the control unit 70 may be communicatively connected to the light-emitting component 20 and the energy storage capacitor 30.

[0195] Thus, the control unit 70 can control the energy storage capacitor to supply power to the light-emitting component based on the detection information detected by the detection component 60, namely the rotation angle of the rolling element 40, so as to realize the light-emitting component emitting light. In this way, the light-emitting operation can be performed once every preset distance.

[0196] Optionally, the detection assembly 60 may include a detection element 61 and a synchronizing element 62. The synchronizing element 62 is connected to the rolling element and is used to rotate synchronously with the rolling element 40.

[0197] The detection element 61 is fixedly connected to the damping structure 50. The detection element 61 is communicatively connected to the control unit 70. The detection element 61 is used to detect the rotation angle of the synchronization element 62 and output detection information to the control unit 70.

[0198] Optionally, the synchronizing element 62 is provided on the abutting roller 42 or the rotating shaft 41 of the rolling element 40.

[0199] In one embodiment, the synchronizing element 62 can be fixedly mounted on a rotating shaft 41, and optionally coaxial with the rotating shaft 41 and / or the abutment roller 42. The synchronizing element 62 can rotate synchronously with the rotation of the rolling element 40.

[0200] Optionally, the detection element 61 can be fixedly mounted on the main body 512 and communicatively connected to the control unit 70. The detection element 61 is positioned corresponding to the synchronizing element 62 in the direction of approaching or moving away from the rolling element 40, and the detection element 61 can detect the rotation angle of the synchronizing element 62 and output detection information to the control unit 70.

[0201] The control unit 70 can receive detection information and determine the rotation angle of the synchronizing member 62 based on the detection information, thereby determining the rotation angle of the rolling member 40.

[0202] When the rotation angle of the rolling element 40 reaches a preset angle, that is, when the skin treatment device 100 moves a preset distance, the control unit 70 can control the energy storage capacitor 30 to release electrical energy to provide power to the light-emitting component 20, so that the light-emitting component 20 can complete one or more light emission.

[0203] Then, the detection element 61 can continue to detect the rotation angle of the synchronization element 62, and the control unit 70 can continue to receive the detection information so as to control the energy storage capacitor 30 to release electrical energy when the rotation angle reaches the preset angle again.

[0204] It is understood that the control unit 70 may be a general-purpose central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits used to control the execution of the above scheme program.

[0205] It is understood that the control unit 70 can achieve communication connection with the energy storage capacitor 30 through electrical connection with the matching circuit of the energy storage capacitor 30; the control unit 70 can also achieve communication connection with the light-emitting component 20 and the detection component 61 through electrical connection.

[0206] It is understood that the detection component 61 can continuously detect the rotation of the synchronization component 62 and output detection information, and the control unit 70 can continuously receive the detection information. After each energy storage capacitor 30 completes the energy release, the obtained rotation angle is reset to zero, and the rotation angle of the rolling component 40 is determined again from zero through the detection component 61. In this way, the detection component 60 can trigger the energy storage capacitor 30 to release energy once every time the rolling component 40 rotates a preset angle, and trigger the light-emitting component 20 to emit light. This allows the skin treatment device 100 to achieve periodic lighting based on the rotation angle of the rolling component 40, that is, the distance the rolling component 40 rolls on the user's skin, and the detection is accurate.

[0207] The damping structure 50 reduces the rotation of the rolling element 40, allowing the energy storage capacitor 30 to complete a charge before the rotation angle of the rolling element 40 reaches a preset angle.

[0208] It can be understood that the skin treatment device 100 achieves periodic lighting by rolling the roller 40 on the skin a preset distance. After the roller 40 moves a preset distance corresponding to a preset angle on the skin, the light-emitting component 20 emits light once or emits light multiple times at a preset frequency. Each emission of light can form a lighting area on the skin.

[0209] In this way, during the use of the skin treatment device 100, the spacing between any two adjacent lighting areas in the area traversed by the working surface 111 on the skin can be equal, improving the uniformity of the lighting area distribution and thus enhancing the uniformity of the lighting on the user's skin by the skin treatment device 100. This reduces the likelihood of the skin treatment effect being affected by increased spacing between lighting areas, and also reduces the need for the user to stop moving the skin treatment device 100 when the working surface 111 is facing the skin, thus minimizing the discomfort caused by repeated lighting on the same area of ​​the skin.

[0210] It is understandable that the length of the rotating shaft 41 connected to the synchronizing element 62 can be greater than the length of the other rotating shaft 41, in order to provide space for the installation of the synchronizing element 62.

[0211] In this application, the types of the detection element 61 and the synchronization element 62 are not specifically limited. For example, the synchronization element 62 can be a magnetic ring, on which one or more pairs of magnetic poles can be provided. Each pair of magnetic poles can include an N pole and a S pole. When multiple pairs of magnetic poles are provided, the multiple pairs of magnetic poles are arranged in a circumferential direction, and each N pole has S poles on both sides, and each S pole has N poles on both sides. The detection element 61 can be a Hall sensor, and the detection information is a pulse signal. Whenever a pair of magnetic poles passes through the detection area of ​​the detection element 61, the Hall sensor can detect the change in the magnetic field, thereby determining that a pair of magnetic poles has passed through the detection area of ​​the Hall sensor, and outputting a detection information to the control unit 70 or the circuit where the control unit 70 is located. Since the number of pole pairs in the magnetic ring is fixed, when the Hall sensor generates a pulse signal by detecting the rotation of the magnetic ring, each pulse indicates that the magnetic ring has rotated by one unit angle. When multiple pulses are generated, the angle that the magnetic ring has rotated can be equal to the product of the unit angle and the number of pulses. Therefore, the control unit 70 can determine the current angle that the synchronization element 62 has rotated based on the detection information generated by the detection element 61 and the number of pole pairs in the synchronization element 62, thereby determining whether the rotation angle of the rolling element 40 has reached the preset angle.

[0212] This application does not specify a particular value for the preset angle. For example, the preset angle can be, but is not limited to, 360 degrees or 720 degrees.

[0213] In this application, the position of the detection element 61 on the main body 512 is not specifically limited. For example, a mounting hole 5122 may be provided on the main body 512, with the mounting hole 5122 and the clearance groove 5121 spaced apart and penetrating the main body 512 in a third direction; the detection element 61 may be fixedly installed in the mounting hole 5122 and protrude from the main body 512 on the third direction through the mounting hole 5122, with the part of the detection element 61 protruding from the main body 512 corresponding to the synchronization element 62.

[0214] In other embodiments, the detection component 60 can also detect the rotation angle of the rolling element 40 using the principles of detection devices such as infrared sensors and photoelectric sensors. For example, the detection component 61 can be a photoelectric sensor, and the synchronization component 62 can be a roller coaxial with the rotating shaft 41 and / or the abutment roller 42. Multiple reflective layers are spaced along the circumferential direction on the outer periphery of the synchronization component 62. The reflective layers can reflect the light emitted by the photoelectric sensor back to the photoelectric sensor, while the outer periphery of the synchronization component 62 cannot reflect the light back to the photoelectric sensor. The photoelectric sensor can output detection information to the control unit 70 when receiving the reflected light. The control unit 70 can determine whether the rotation angle of the rolling element 40 has reached a preset angle based on the received detection information and the number of reflective layers on the synchronization component 62.

[0215] In other cases, the damping structure 50 can adjust the damping force on the rolling element 40 through a mating relationship other than abutment, thereby adjusting the rotational speed of the rolling element 40. For example, the damping structure 50 can be a damping device commonly used in related fields such as rotary dampers and electromagnetic dampers; rotary dampers are used to reduce the rotational speed of the rolling element 40 through viscous fluid, and electromagnetic dampers are used to reduce the rotational speed of the rolling element 40 through magnetic force.

[0216] For example, the damping structure 50 can be a rotary damper, which can be fixedly installed on the working end 11 and can be sleeved on the rotating shaft 41. The rotary damper can contain viscous fluid, and the hydraulic pressure generated by the viscous fluid generates a damping force on the rolling element 40, slowing down the rotation of the rolling element 40, thereby reducing the speed at which the rolling element 40 rolls on the skin.

[0217] For example, the damping structure 50 can be an electromagnetic damper, which can be fixedly installed on the working end 11 and connected to a rotating shaft 41. The rotating shaft 41 can be made of ferromagnetic material and fixedly connected to the abutment roller 42. When the electromagnetic damper is working, it can generate magnetic force to produce a damping force on the rolling element 40, slowing down the rotation of the rolling element 40, thereby reducing the speed at which the rolling element 40 rolls on the skin. The electromagnetic damper can adjust the rotational speed level of the rolling element 40 by adjusting the operating current, voltage and / or power.

[0218] It is understood that the rotary damper and the rolling element 40 can have at least a first engagement state and a second engagement state, and the electromagnetic damper and the rolling element 40 can have at least a first engagement state and a second engagement state. The relevant principles can be found in the above description of the adjustment of the contact engagement state between the damper 51 and the rolling element 40, which will not be repeated here.

[0219] In this application, the damping force on the rolling element 40 can be greater than or equal to 0.3N and less than or equal to 7N, and can be selected from 0.3N to 5N. For example, the damping force on the rolling element 40 can be 0.3N, 0.4N, 0.5N, 0.6N, 0.7N, 0.8N, 0.9N, 1N, 1.1N, 1.2N, 1.3N, 1.4N, 1.5N, 1.6N, 1.7N, 1.8N, 1.9N, 2N, 2.1N, 2.2N, 2.3N, 2.4N, 2.5N, 2.6N, 2.7N, 2.8N, 2.9N, 3N, 3.1N, 3.2N, 3.3N, 3.4N,

[0220] 3.5N, 3.6N, 3.7N, 3.8N, 3.9N, 4N, 4.1N, 4.2N, 4.3N, 4.4N, 4.5N, 4.6N, 4.7N,

[0221] 4.8N, 4.9N, 5N, 5.5N, 6N, 6.5N or 7N.

[0222] If the damping force on the rolling element 40 is too small, such as less than 0.3N, the damping structure 50 will have a smaller limiting effect on the rotation speed of the rolling element 40, which will make it difficult to avoid the skin treatment device 100 moving too fast on the skin surface.

[0223] If the damping force on the rolling element 40 is too large, such as greater than 5N or 7N, the damping structure 50 will have a greater limiting effect on the rotation speed of the rolling element 40. In this case, a large force will be required to drive the rolling element 40 to rotate, which may cause discomfort to the user.

[0224] This application limits the damping force on the rolling element 40 to between 0.3N and 5N, ensuring that the damping structure 50 appropriately restricts the rotational speed of the rolling element 40. This effectively prevents the skin treatment device 100 from moving too quickly across the skin surface, while also preventing discomfort caused by excessive force or pressure from the user. Thus, it improves both the skin treatment effect and the user experience of the skin treatment device 100.

[0225] When the rolling element 40 is in the first engagement state, that is, when the skin treatment device 100 is in the facial treatment mode, the damping force on the rolling element 40 can be greater than or equal to 0.3N and less than or equal to 1N.

[0226] When the rolling element 40 is in the second engagement state, that is, when the skin treatment device 100 is in the limb treatment mode, the damping force on the rolling element 40 can be greater than or equal to 0.8N and less than or equal to 5N.

[0227] It is understandable that by obtaining experimental results involving multiple people, the relative relationship between the value of the damping force on the rolling element 40 and the person's physical sensation can be obtained.

[0228] The experimental results obtained by selecting one hundred people to participate in the experiment, and the relationship between the damping force and the body sensation when the rolling element 40 is in the first engagement state, are shown in Table 1:

[0229] Table 1

[0230] 0.3N 82％ 18％ 0 0.4N 80％ 18％ 2％ 0.5N 80％ 12％ 8％ 0.6N 74％ 16％ 10％ 0.7N 72％ 12％ 16％ 0.8N 70％ 10％ 20％ 0.9N 62％ 12％ 26％ 1N 61％ 11％ 28％

[0231] Table 1 indicates that when the rolling element 40 is in the first engagement state, and the damping force on the rolling element 40 is between 0.3N and 0.8N, the proportion of people experiencing discomfort can be maintained below 20%. As the damping force increases, the proportion of people experiencing discomfort increases accordingly. Therefore, the damping force corresponding to maintaining the proportion of people experiencing discomfort below 20% can be defined as the damping force that the rolling element 40 can withstand when in the first engagement state.

[0232] The experimental results obtained by selecting one hundred people to participate in the experiment, and the relationship between the damping force and the body sensation when the rolling element 40 is in the second engagement state, are shown in Table 2:

[0233] Table 2

[0234] 0.4N 82％ 18％ 0 0.6N 82％ 18％ 0 0.8N 84％ 16％ 0 0.9N 85％ 15％ 0 1N 85％ 15％ 0 1.1N 85％ 15％ 0 1.2N 85％ 15％ 0 1.5N 83％ 17％ 0 2N 81％ 18％ 1％ 2.5N 80％ 18％ 2％ 3N 80％ 18％ 2％ 3.5N 76％ 18％ 6％ 4N 74％ 13％ 13％ 4.5N 74％ 11％ 15％ 4.6N 72％ 12％ 16％ 4.7N 70％ 14％ 16％ 4.8N 70％ 12％ 18％ 4.9N 66％ 15％ 19％ 5N 62％ 19％ 19％ 5.1N 58％ 20％ 22& 5.2N 56％ 16％ 26％ 5.5N 52％ 10％ 28％

[0235] Table 2 indicates that when the rolling element 40 is in the second engagement state, and the damping force on the rolling element 40 is less than 0.8N, the number of people experiencing various sensations does not change as the damping force on the rolling element 40 increases. However, when the damping force reaches 0.8N, the proportion of people experiencing a comfortable sensation increases. Therefore, it can be determined that when the damping force on the rolling element 40 is less than 0.8N, the damping force is too small to cause a change in the user's sensation, or the change in the damping force is insufficient for the user to feel resistance while moving the skin treatment device 100. In this case, the moving speed of the skin treatment device 100 may increase, thus affecting the skin treatment effect. However, when the damping force on the rolling element 40 reaches 0.8N, it can cause a change in the user's sensation, and the user can slow down the movement of the skin treatment device 100 based on the change in sensation.

[0236] Meanwhile, when the rolling element 40 is in the second engagement state, and the damping force on the rolling element 40 is between 0.8 and 5 N, the proportion of people experiencing discomfort can be kept below 20%. As the damping force increases, the proportion of people experiencing discomfort increases accordingly. Therefore, the damping force that causes a change in user sensation when the proportion of people experiencing discomfort is kept below 20% can be defined as the damping force that the rolling element 40 can withstand when in the second engagement state.

[0237] The skin treatment device 100 provided by the embodiments of this application, by providing a rolling element 40 at the working end 11, can guide the skin treatment device 100 to move on the user's skin surface, improving the frictional discomfort between the working surface and the user's skin, thereby improving the user's comfort in operating the skin treatment device 100 on the skin surface; and by providing a damping structure 50 that cooperates with the rolling element 40, the damping force experienced by the rolling element 40 during rolling can be changed to limit the movement speed of the rolling element 40 and the skin treatment device 100 on the skin surface, thereby preventing the skin treatment device 100 from moving too fast on the skin surface, allowing the skin treatment device 100 to have a longer working time in each area to be treated, so that the nursing energy emitted by the skin treatment device 100 can better act on the skin to be treated, thereby ensuring or improving the skin treatment effect.

[0238] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments described above should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application.
