Description

Technical Field

[0001] This invention relates to the field of physical massage and care equipment technology, and in particular to a head-mounted scalp massage and care device. Background Technology

[0002] Most existing scalp massage and care devices use handheld massage combs, scalp massagers, or fixed massage structures. These devices typically present the following problems during actual use: (1) The massage components are not well adapted to the contours of the top and sides of different users' heads, and are prone to problems such as insufficient local fit, excessive local pressure, or uneven massage coverage. (2) Massage components usually lack a stable floating compensation structure, making it difficult to automatically adjust the contact position and contact depth according to the changes in the curvature of the scalp, thus affecting the massage comfort and uniformity; (3) The devices generally lack detection and feedback control of scalp contact pressure, and cannot dynamically adjust the massage intensity according to the contact state, which can easily cause unstable massage output or excessive local stimulation. (4) The existing driving method is relatively simple and it is difficult to form a continuous massage effect along the scalp area, resulting in a limited massage reach; (5) The connection between the controller and the wearer is not stable enough, and there is no convenient storage and charging structure after use, which affects the reliability and daily convenience of the device.

[0003] Therefore, it is necessary to provide a head-mounted scalp massage and care device to improve scalp fit, massage uniformity, user comfort, and control stability, and to integrate wearing care, controller assembly / disassembly, storage, and charging. Summary of the Invention

[0004] To at least solve one of the above-mentioned technical problems in the prior art, the present invention aims to provide a head-mounted scalp massage and care device.

[0005] The objective of this invention is achieved through the following technical solution: A headband-style scalp massage and care device includes a headband, a controller, and a makeup mirror. The headband includes a headband body, a flexible light panel, at least one massage component, at least one vibration drive, at least one pressure detection unit, and a first connecting base. The headband body includes an elastic support frame that matches the contour of the head and a skin-fitting mounting frame disposed inside the elastic support frame. Each massage component is disposed on the skin-fitting mounting frame, and each massage component, each vibration drive, and each pressure detection unit are correspondingly arranged. Each massage component includes a floating mounting base, an elastic comb bar disposed on the floating mounting base, and a comb bar disposed on the elastic support. Multiple flexible comb teeth on the rack; each of the vibration driving components is respectively disposed between the corresponding skin-fitting mounting frame and the floating mounting base, or connected at one end to the skin-fitting mounting frame and at the other end to the floating mounting base, so as to drive the corresponding floating mounting base to cause the elastic comb teeth to generate tangential reciprocating displacement and / or normal micro-vibration displacement relative to the scalp, thereby performing a rubbing massage on the scalp; each of the pressure detection units is respectively disposed between the corresponding skin-fitting mounting frame and the floating mounting base, or disposed on the force transmission path between the floating mounting base and the skin-fitting mounting frame, for detecting the pressure of the corresponding massage component relative to the skin-fitting mounting frame. The pressure state characterizes the local contact pressure between the corresponding massage component and the scalp; the flexible light panel is disposed on the headband body and emits light towards the scalp; the first connecting seat is provided with a first electrical connection terminal, which is electrically connected to each of the vibration driving components, each of the pressure detection units, and the flexible light panel; the controller is provided with a battery, a control module, and a second electrical connection terminal, which is electrically connected to the battery and the second electrical connection terminal; the makeup mirror is provided with a headband suspension part, a second connecting seat, and a power input terminal, and the second connecting seat is provided with a third electrical connection terminal electrically connected to the power input terminal; the headband The controller is detachably hung on the headband suspension part; the controller is detachably connected to the first connecting seat, and the second electrical connection terminal is electrically connected to the first electrical connection terminal, so that the battery supplies power to each of the vibration driving components, each of the pressure detection units and the flexible lamp board, and the control module controls the driving frequency and / or driving amplitude of each of the vibration driving components according to the detection results of each of the pressure detection units, and controls the operation of the flexible lamp board; the controller can also be detachably installed on the second connecting seat and electrically connected to the third electrical connection terminal, so that the power input terminal charges the controller through the third electrical connection terminal.

[0006] By integrating massage components, vibration drive components, pressure detection units, controllers, and a cosmetic mirror into the headband, the device can perform mechanical scalp massage care, control power supply, controller assembly / disassembly, storage, and charging while being worn. This improves the overall integration, ease of use, and stability of scalp care devices. Consequently, it helps to solve the problems of fragmented functions, insufficient stability of wearable massage, and inconvenience in storage and charging after use in existing scalp massage devices.

[0007] Furthermore, each of the floating mounting bases includes a mounting base body, the mounting base body having at least one guide hole, and the skin-fitting mounting bracket having at least one guide post corresponding to and cooperating with the guide hole, the guide post being inserted into the guide hole; a reset elastic element is provided between the mounting base body and the skin-fitting mounting bracket, the reset elastic element being used to drive the mounting base body to reset towards the scalp side; at least one of the skin-fitting mounting bracket and the mounting base body has a limiting part, the limiting part being used to limit the maximum displacement stroke of the mounting base body along the axial direction of the guide post; the vibration driving element and the pressure detection unit are respectively disposed between the mounting base body and the skin-fitting mounting bracket; the elastic comb bar is disposed on the mounting base body, so that the mounting base body can drive the elastic comb bar to float relative to the skin-fitting mounting bracket along the scalp normal.

[0008] By setting up a floating mounting structure including a mounting body, guide pillars, guide holes, a reset elastic element, and a limiting part, the massage component can float relative to the skin-fitting mounting frame along the normal direction of the scalp and maintain a moderate fit with the scalp under pre-tightening action. This improves the contact consistency of different scalp areas and enhances massage comfort and stability. As a result, it helps to solve the problems of existing massage components being unable to adapt to changes in the curvature of the scalp, insufficient local fit, or excessive local pressure.

[0009] Furthermore, the headband body also includes a flexible panel and a skin-contact panel, with the flexible light panel disposed between the flexible panel and the skin-contact panel; the skin-contact panel is a light-transmitting panel, or the skin-contact panel has a light-transmitting area, so that the care light emitted by the flexible light panel passes through the skin-contact panel or the light-transmitting area to the scalp side; the flexible light panel is used to emit at least one care light among red light, near-infrared light and blue light.

[0010] By placing a flexible light panel between the flexible panel and the skin-contact panel, and allowing the care light to shine through the light-transmitting plate or area onto the scalp, auxiliary care functions can be provided on top of mechanical massage care, thereby enriching the care methods and usage scenarios of the device; thus, it helps to solve the problem of the limited care methods of existing scalp care devices.

[0011] Furthermore, the control module calculates the average contact pressure Pavg, pressure dispersion σP, and contact coverage coefficient η based on the pressure values ​​Pi collected by each pressure detection unit, where: Where n is the number of pressure detection units, i is the sequence number of the pressure detection unit, wi is the weight coefficient of the corresponding detection point, Pth is the contact determination threshold, and I (Pi≥Pth) is the indicator function value corresponding to the i-th detection point.

[0012] By calculating the average contact pressure, pressure dispersion, and contact coverage coefficient based on the pressure values ​​collected by each pressure detection unit, the overall fit, pressure uniformity, and effective coverage between the massage component and the scalp can be quantitatively characterized, thus providing a basis for subsequent drive control. This helps to solve the problem of existing scalp massage devices lacking contact state recognition and quantitative feedback.

[0013] Furthermore, the control module determines the common fundamental driving frequency f and fundamental driving amplitude A of each vibration actuator based on the average contact pressure Pavg, the pressure dispersion σP, and the contact coverage coefficient η, and satisfies: f=min{fmax, max[fmin, f0+k1·η-k2·σP]} A=min{Amax, max[Amin, A0+k3·(Pavg-Pref)]} Where f0 and A0 are the initial frequency and initial amplitude, respectively; fmin, fmax, Amin, and Amax are the upper and lower limits of frequency and amplitude, respectively; Pref is the target contact pressure; and k1, k2, and k3 are control coefficients.

[0014] By determining the basic driving frequency and basic driving amplitude based on the average contact pressure, pressure dispersion, and contact coverage coefficient, the output of the vibration drive component can be adapted to the actual contact state of the scalp, thereby improving the targeting, uniformity, and comfort of the massage output. This helps to solve the problem of existing massage devices having fixed output modes and difficulty in dynamically adjusting the massage intensity according to the contact state.

[0015] Furthermore, the control module employs phase difference drive control for each of the vibration drive components arranged along the length direction of the headband body under the basic drive frequency f and the basic drive amplitude A, wherein the drive phase difference between two adjacent vibration drive components satisfies: φm=(m-1)Δφ, m=1, 2,…,n Wherein, φm is the driving phase of the m-th vibration actuator, and φ is the phase difference between adjacent vibration actuators, so as to form a massage wave moving along the length direction on the headband body, thereby realizing a scanning massage of the scalp; the control module has a safety control strategy, which reduces the basic driving frequency f and / or the basic driving amplitude A when η<η0 or Pmax>Plim, or stops all massage components from working; wherein, η0 is the minimum coverage coefficient threshold, Pmax is the maximum contact pressure value at each detection point, and: Pmax = max(P1, P2, ..., Pn) Plim is the upper limit of safe pressure.

[0016] By employing phase difference drive control for multiple vibration actuators, a massage wave that moves along the length of the headband body can be formed, thereby achieving a scanning massage of the scalp, expanding the massage reach and improving the uniformity of massage coverage. At the same time, by setting a safety control strategy, the drive output can be reduced or the operation can be stopped when there is insufficient contact or excessive local pressure, thereby improving the safety of care and the stability of control. This helps to solve the problems of limited massage range and continuous high-intensity output under abnormal conditions in existing devices.

[0017] Furthermore, the first electrical connection terminal includes a first signal contact, a first positive contact, and a first negative contact, and the second electrical connection terminal includes a second signal contact, a second positive contact, and a second negative contact; when the controller is connected to the first connector, the first signal contact is electrically connected to the second signal contact, the first positive contact is electrically connected to the second positive contact, and the first negative contact is electrically connected to the second negative contact.

[0018] By setting corresponding signal contacts, positive contacts, and negative contacts, the controller can stably achieve power supply and signal transmission after being connected to the first connector, thereby improving the connection reliability of the vibration drive, pressure detection unit, and related control functions during operation; thus, it helps to solve the problem of unstable connection between the existing detachable controller and the wearer.

[0019] Furthermore, the first connecting seat is provided with a magnetic component or a magnetic conductive component, and a flange is provided on the side wall of the first connecting seat, forming a slot between the flange and the side wall; the controller is provided with a snap-fit ​​cavity, and a magnetic component or a magnetic conductive component is provided in the snap-fit ​​cavity to magnetically engage with the first connecting seat, and a snap hook is formed on one side edge of the snap-fit ​​cavity; the first connecting seat is inserted into the snap-fit ​​cavity through the entrance of the snap-fit ​​cavity, and by moving the controller and / or the hairband relative to each other along the length direction of the first connecting seat, the snap hook is snapped into the slot, so as to achieve a composite fixation of magnetic guidance and mechanical snap-fit.

[0020] By combining the magnetic pre-positioning structure with the mechanical snap-fit ​​structure, the controller can be quickly aligned when connected to the first connector, and can maintain a reliable anti-detachment fixation state after connection, thereby improving the convenience of disassembly and assembly and the connection stability during wear; thus, it helps to solve the problem of existing controllers being loosely connected and easily loosening during use.

[0021] Furthermore, the makeup mirror includes a frame, a lens, a support arm, a base, a second connecting seat, and a power input terminal; the lens is disposed within the frame, one end of the support arm is fixedly connected to the base, and the other end is rotatably connected to the frame; the makeup mirror also includes a hairband hanging part, the frame includes a base plate and a frame body, and the outer periphery of the frame body and the base plate define the hairband hanging part for hanging the hairband.

[0022] By incorporating a headband hanging part, a second connecting seat, and a power input terminal into the makeup mirror, the makeup mirror can function as both a headband hanger and a controller charger, thereby improving the ease of tidying up the device after daily care and enhancing its overall integration. This helps to solve the problem of existing scalp massage care devices lacking supporting storage and charging structures.

[0023] Furthermore, the free ends of each of the flexible comb teeth together form an arc-shaped envelope that matches the contour of the top of the human head, and the length of the flexible comb teeth located in the middle region of the width of the headband body is greater than the length of the flexible comb teeth located on both sides, so that the massage component forms a differentiated contact depth in the top and sides of the scalp, thereby improving scalp fit and massage uniformity.

[0024] By making the flexible comb teeth form an arc-shaped envelope that matches the contour of the top of the human head, and by making the length of the flexible comb teeth in the middle area greater than that in the side areas, the massage components can form a more reasonable differentiated contact depth in the top and side scalp areas, thereby improving the scalp fit, enhancing massage uniformity and care comfort; thus, it helps to solve the problem that existing comb tooth structures cannot simultaneously achieve a good fit in the top and side scalp areas.

[0025] The beneficial effects of this invention are as follows: (1) By setting a massage component, a vibration drive component and a pressure detection unit on the headband, the present invention enables the device to perform mechanical massage care on the scalp while being worn, and can be adjusted according to the actual contact state of the scalp, thereby improving the fit, uniformity and stability of scalp care.

[0026] (2) The present invention enables the massage component to adapt to the curvature of different scalp areas through the combination of floating mounting base, guide structure, reset elastic element and flexible comb teeth, and to form a more reasonable contact depth in the top and side areas of the head, thereby improving the fit between the massage component and the scalp and improving massage comfort and massage uniformity.

[0027] (3) The present invention detects local contact pressure through a pressure detection unit, and the control module adjusts the driving frequency, driving amplitude and phase difference of the vibration drive component according to the detection results. At the same time, it executes a safety control strategy in abnormal conditions, so that the massage output is more matched with the scalp contact state, which is conducive to improving the safety, pertinence and control reliability of the nursing process.

[0028] (4) The present invention realizes the matching setup of controller assembly and disassembly, hairband storage and controller charging through the detachable connection structure between the controller and the first connecting seat, the hairband hanging part on the makeup mirror and the second connecting seat, thereby improving the convenience of the device in daily use, connection stability and overall integration.

[0045] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0046] Combination Figures 1 to 16 As shown, a headband-style scalp massage and care device includes a headband 100, a controller 16, and a makeup mirror 26. The headband 100 includes a headband body, a first connecting seat 2, ear hooks 3, flexible ear hooks 4, and a decorative sleeve 5. The headband body includes an elastic support frame 6 that matches the contour of the human head and a skin-fitting mounting frame 7 disposed inside the elastic support frame 6. Preferably, the elastic support frame 6 has an arc-shaped structure that is wider in the middle and narrower on both sides to adapt to the contour of the top and sides of the head; the skin-fitting mounting frame 7 is fixedly connected to the elastic support frame 6, and its inner side is used to install one or more massage components 8. Preferably, there are multiple massage components 8, which are spaced apart along the length of the headband body.

[0047] Each massage component 8 includes a floating mounting base, an elastic comb bar 10 disposed on the floating mounting base, and a plurality of flexible comb teeth 15 disposed on the elastic comb bar 10. The free ends of each of the flexible comb teeth 15 together form an arc-shaped envelope surface that matches the contour of the top of the human head, and the length of the flexible comb teeth 15 located in the middle region of the width of the headband body is greater than the length of the flexible comb teeth 15 located in the side regions, so that the massage component 8 forms a differentiated contact depth in the top and side scalp regions of the head, thereby improving scalp fit and massage uniformity.

[0048] In this embodiment, each of the floating mounting bases includes a mounting base body 9, which has at least one guide hole 12. The skin-fitting mounting bracket 7 has at least one guide post 11 corresponding to and cooperating with the guide hole 12, and the guide post 11 is inserted into the guide hole 12. A reset elastic element 13 is provided between the mounting base body 9 and the skin-fitting mounting bracket 7, which is used to drive the mounting base body 9 to reset towards the scalp side. At least one of the skin-fitting mounting bracket 7 and the mounting base body 9 has a limiting part 14, which is used to limit the maximum displacement stroke of the mounting base body 9 along the axial direction of the guide post 11. Thus, the mounting base body 9 can float relative to the skin-fitting mounting bracket 7 along the scalp normal to adapt to the curvature changes of different scalp areas.

[0049] The headband body is also provided with at least one vibration drive component 21 and at least one pressure detection unit 22, and each of the massage components 8, each of the vibration drive components 21 and each of the pressure detection units 22 are arranged in a one-to-one correspondence. Each of the vibration drive components 21 is respectively disposed between the corresponding skin-fitting mounting bracket 7 and the floating mounting seat, or one end is connected to the skin-fitting mounting bracket 7 and the other end is connected to the floating mounting seat, so as to drive the corresponding floating mounting seat to drive the elastic comb bar 10 to generate tangential reciprocating displacement and / or normal micro-vibration displacement relative to the scalp, thereby performing a rubbing massage on the scalp. Each of the pressure detection units 22 is respectively disposed between the corresponding skin-fitting mounting bracket 7 and the floating mounting seat, or disposed on the force transmission path between the floating mounting seat and the skin-fitting mounting bracket 7, for detecting the pressure state of the corresponding massage component 8 relative to the skin-fitting mounting bracket 7, and characterizing the local contact pressure between the corresponding massage component 8 and the scalp.

[0050] The headband body further includes a flexible panel 42 and a skin-contact panel 43, with a flexible light panel 44 disposed between the flexible panel 42 and the skin-contact panel 43. The skin-contact panel 43 is a light-transmitting panel, or the skin-contact panel 43 has a light-transmitting area, so that the care light emitted by the flexible light panel 44 passes through the skin-contact panel 43 or the light-transmitting area to the scalp side. The flexible light panel 44 is used to emit at least one care light among red light, near-infrared light, and blue light; in some embodiments, the flexible light panel 44 may also include a light-emitting element for emitting LLLT low-energy laser.

[0051] The headband body is provided with a first connecting seat 2, which is preferably located near the end of the headband body. The first connecting seat 2 is provided with a first electrical connection terminal 23, which is electrically connected to each of the vibration driving components 21, each of the pressure detection units 22, and the flexible lamp plate 44, for receiving power and / or control signals. Preferably, the first electrical connection terminal 23 includes a first signal contact, a first positive contact, and a first negative contact.

[0052] The headband body has an ear hook plate 3 at one end, which is preferably an elastic plastic sheet. A flexible ear hook 4 is fitted onto the ear hook plate 3 and fits snugly behind the ear. Preferably, the flexible ear hook 4 has multiple protrusions 50 spaced apart in the corresponding contact area behind the ear to improve contact comfort and wearing stability. A decorative sleeve 5 is fitted onto the headband body, concealing the connection gap between the flexible ear hook 4 and the headband body, thereby enhancing the overall aesthetic integrity.

[0053] The controller 16 includes a battery 17, a control module 18, a second electrical connection terminal 19, and a snap-fit ​​cavity 20. The control module 18 is electrically connected to the battery 17 and the second electrical connection terminal 19. The controller 16, as an external control and power supply unit, is detachably connected to the first connecting base 2, and the second electrical connection terminal 19 is electrically connected to the first electrical connection terminal 23. This allows the battery 17 to supply power to each of the vibration drive components 21, each of the pressure detection units 22, and the flexible lamp panel 44. The control module 18 controls the output parameters of each vibration drive component 21 based on the detection results of each pressure detection unit 22, and controls the operation of the flexible lamp panel 44. Preferably, the second electrical connection terminal 19 includes a second signal contact, a second positive contact, and a second negative contact.

[0054] To enable those skilled in the art to more clearly understand the parameter calculation logic of the control module 18, this embodiment explains the mathematical source of each formula, the meaning of the variables, and the engineering rewriting method of this application based on the principle as follows.

[0055] (i) The formula for the average contact pressure Pavg is derived from the weighted average formula in mathematics. The basic form of the weighted average formula is "the weighted average is equal to the sum of the products of each measurement value and its corresponding weight, divided by the sum of the weights", which is used to reflect the comprehensive level of multiple measurement points when considering different levels of importance. In this application, each pressure detection unit 22 is distributed at different massage components 8. In order to avoid the influence of different positions on the overall contact state being weakened by simple averaging, a weighting coefficient wi is introduced to correct the importance of each detection point, thereby obtaining the average contact pressure Pavg used to characterize the overall contact level.

[0056]

[0057] Among them, Pavg represents the average contact pressure; Pi represents the pressure value collected by the i-th pressure detection unit 22; n represents the number of pressure detection units 22; i represents the serial number of the pressure detection unit; wi represents the weight coefficient of the i-th detection point. The weight coefficient wi can be preset according to the importance of the massage component 8 in the top, middle or side regions of the head; in a preferred embodiment, the importance of each detection point is approximately the same, and w1 = w2 =... = wn = 1 can be taken.

[0058] (2) The formula of the pressure discrete quantity σP is derived from the weighted variance and weighted standard deviation formulas in probability statistics. The standard deviation is used to reflect the degree of dispersion of a set of measured values around the average value. In this application, in order to evaluate whether the pressure-receiving states of the massage components 8 are uniform, the idea of the standard deviation is introduced into the pressure distribution analysis, and an engineering modification is carried out in combination with the weight coefficients of each detection point, so as to obtain the pressure discrete quantity σP. The smaller σP is, the smaller the pressure difference between the pressure detection points is, and the more uniform the scalp fitting is; the larger σP is, the more obvious the situation of local overpressure or underpressure exists.

[0059]

[0060] Among them, σP represents the pressure discrete quantity; (Pi - Pavg)^2 represents the square deviation of the i-th detection point relative to the average contact pressure; the meanings of the remaining variables are the same as those described above. This formula can be understood as follows: first calculate the deviation of each detection point relative to the average contact pressure, then perform a weighted summation in combination with the weights, then divide by the total weight to obtain the weighted variance, and finally take the square root to obtain the pressure discrete quantity in the form of a weighted standard deviation.

[0061] (3) The formula of the contact coverage coefficient η is derived from the idea of threshold determination and coverage rate calculation in statistics. Its basic principle is: first judge whether a single detection point meets the effective contact condition, and then count the proportion of the detection points that meet the effective contact condition in the overall. In this application, in order to determine whether an effective contact is formed between each massage component 8 and the scalp, a contact determination threshold Pth is set, and each detection point is binarized through an indicator function: when Pi ≥ Pth, I(Pi ≥ Pth) takes 1; when Pi < Pth, I(Pi ≥ Pth) takes 0.

[0062]

[0063] Among them, η represents the contact coverage coefficient; Pth represents the contact determination threshold; I(Pi ≥ Pth) represents the value of the indicator function corresponding to the i-th detection point. This formula is used to reflect the weighted proportion of the detection points that meet the effective contact condition among all the detection points. The larger η is, the more sufficient the effective contact coverage of the scalp is; the smaller η is, the more contact-deficient areas exist.

[0064] (iv) The formulas for the basic drive frequency f and the basic drive amplitude A are derived from the linear correction and limiting processing method in engineering control. The original idea is to use a preset reference value as the center, adjust the output proportionally according to the state deviation, and keep the output within a safe and effective range through upper and lower limit constraints. Unlike the common pure fixed output method, this application does not use a fixed frequency and fixed amplitude, but rather adaptively corrects the output based on the average contact pressure, pressure dispersion, and contact coverage coefficient to match the massage output with the actual scalp contact state.

[0065] f=min{fmax, max[fmin, f0+k1·η-k2·σP]} A=min{Amax, max[Amin, A0+k3·(Pavg-Pref)]} Where f represents the basic driving frequency; f0 represents the initial frequency; fmin and fmax represent the lower and upper limits of the basic driving frequency, respectively; A represents the basic driving amplitude; A0 represents the initial amplitude; Amin and Amax represent the lower and upper limits of the basic driving amplitude, respectively; k1, k2, and k3 are control coefficients; and Pref represents the target contact pressure. The derivation logic of the above formula is as follows: First, the initial frequency f0 and the initial amplitude A0 are used as reference values, and then η, σP, and (Pavg-Pref) are introduced as correction terms. Among them, an increase in η usually indicates improved effective contact coverage, and the frequency can be appropriately increased, so a positive correction term k1η is used; an increase in σP usually indicates uneven pressure distribution, and the frequency can be appropriately reduced to avoid excessive local stimulation, so a negative correction term -k2σP is used; the deviation of Pavg from Pref is used to correct the driving amplitude so that the system gradually approaches the target contact state. Finally, the amplitude is limited by the combination of min and max to keep f and A within the preset safety range.

[0066] (v) The phase difference control formula φm=(m-1)Δφ is derived from the phase recursion setting method commonly used in vibration systems or multi-actuator units. Its basic principle is: to assign an initial phase to the first actuator, and then to superimpose a fixed phase difference on subsequent actuators in sequence, thereby forming a phase progressive distribution in space. This application utilizes this principle to form a staggered phase relationship between multiple vibration drive components 21 arranged along the length direction of the headband body, thereby forming a massage wave moving along the length direction in the scalp area to achieve scanning massage.

[0067] φm=(m-1)Δφ,i=1,2,…,n Where φm represents the driving phase of the m-th vibration drive 21; Δφ represents the phase difference between adjacent vibration drive 21.

[0068] (vi) The safety control strategy originates from the threshold protection concept in engineering control. Its basic logic is: when the system detects insufficient coverage or local pressure exceeding the safety limit, it protects operational safety by reducing output or stopping operation. In this application, when η < η0 or Pmax > Plim, the control module 18 executes the safety control strategy, where η0 represents the minimum coverage coefficient threshold, Pmax represents the maximum contact pressure value at each detection point, and Plim represents the safety pressure limit. Pmax can be determined by the following formula: Pmax = max(P1, P2, ..., Pn) Therefore, when the system determines that the scalp contact coverage is insufficient or the local pressure is too great, it can promptly reduce the basic drive frequency f and / or the basic drive amplitude A, or stop all massage components 8 from working, in order to avoid continuous high-intensity massage when the wearer is misaligned, there is insufficient contact, or the local pressure is too great.

[0069] The target contact pressure Pref is not arbitrarily set, but rather a reference pressure value used to characterize "ensuring stable contact between the massage component 8 and the scalp without causing significant pressure discomfort." Its setting should comprehensively consider the following factors: first, the stiffness and rebound characteristics of the flexible comb teeth 15 and the elastic comb strips 10; second, the output capability of the vibration drive component 21 and its displacement component in the scalp normal direction; third, the comfortable pressure range for different scalp areas; and fourth, the range, resolution, and linearity interval of the pressure detection unit 22.

[0070] In one exemplary configuration, a comfortable and effective contact pressure range [Plow, Phigh] can be determined first through prototype testing. Plow can be defined as the minimum pressure at which the massage component 8 can stably conform to the scalp and maintain continuous massage, while Phigh can be defined as a higher pressure that does not cause significant discomfort under continuous operating conditions. Subsequently, the midpoint or weighted midpoint of this range can be taken as the target contact pressure Pref, for example: Pref = (Plow + Phigh) / 2. In some embodiments, Pref can also be regionalized based on the importance of the top and side areas of the head. Setting Pref in this manner allows the control module 18 to adjust the average contact pressure Pavg to a more reasonable range under different wearing conditions, thereby balancing fit stability, massage comfort, and control sensitivity.

[0071] Furthermore, the first connecting seat 2 is provided with a magnetic component or a magnetically conductive component, and the snap-fit ​​cavity 20 is provided with a magnetic component or a magnetically conductive component that magnetically engages with the first connecting seat 2, so that the controller 16 can be pre-positioned by magnetic attraction when connected to the first connecting seat 2. A flange 24 is provided on the side wall of the first connecting seat 2, and a slot 25 is formed between the flange 24 and the side wall. The length of the snap-fit ​​cavity 20 is greater than the length of the first connecting seat 2, the entrance contour of the snap-fit ​​cavity 20 matches the outer contour of the first connecting seat 2, and a hook 34 is formed on one side edge of the snap-fit ​​cavity 20. During assembly, the first connecting seat 2 is inserted into the snap-fit ​​cavity 20 through the entrance, and by moving the controller 16 and / or the headband body, the hook 34 is engaged in the slot 25, thereby achieving the snap-fit ​​fixation of the controller 16 and the headband body.

[0072] Preferably, the first connecting seat 2 is located on the headband body near the end, and the flange 24 is located on the side of the first connecting seat 2 opposite to the end. After the controller 16 is connected to the first connecting seat 2, the controller 16 slides along the length direction of the first connecting seat 2 towards the side where the flange 24 is located under the action of gravity, so that the hook 34 is engaged in the slot 25, thereby preventing the controller 16 from falling off. Thus, a detachable connection structure combining magnetic pre-positioning and snap-fit ​​anti-detachment is formed between the controller 16 and the headband 100.

[0073] The cosmetic mirror 26 includes a frame 27, a lens 28, a support arm 29, a base 30, a second connecting seat 31, and a power input terminal 32. The lens 28 is disposed within the frame 27. One end of the support arm 29 is fixedly connected to the base 30, and the other end is rotatably connected to the frame 27. Preferably, the support arm 29 is inclined on the base 30, and the angle between the support arm 29 and the base 30 is less than 90°. The projection of the center of gravity of the frame 27 on the horizontal plane is located within the support range of the base 30 to improve overall stability. The bottom of the base 30 is provided with soft, non-slip pads. The rotation angle of the frame 27 relative to the support arm 29 is preferably 15° to 45°. In some embodiments, a damping rotation assembly 431 may also be provided between the frame 27 and the support arm 29 to provide damping for the rotation of the frame 27 relative to the support arm 29.

[0074] The second connector 31 is disposed on the makeup mirror 26, and the second connector 31 is provided with a third electrical connection terminal 33, which is electrically connected to the power input terminal 32. The controller 16 can also be detachably installed on the second connector 31 and electrically connected to the third electrical connection terminal 33, so that the power input terminal 32 charges the controller 16 through the third electrical connection terminal 33.

[0075] In addition, the makeup mirror 26 is also provided with a hairband hanging part 40 for hanging a hairband 100. Preferably, the mirror frame 27 includes a base plate 38 and a frame 39. The frame 39 is an elliptical frame that matches the shape of the hairband 100, and the size of the frame 39 is smaller than the size of the base plate 38. The frame 39 is disposed on the base plate 38, and the outer periphery of the frame 39 and the base plate 38 define the hairband hanging part 40. The lens 28 matches the shape of the frame 39 and is disposed on the frame 39. The outer wall of the frame 39 is provided with at least one anti-slip rib 41 to prevent the hairband 100 hanging on the hairband hanging part 40 from slipping off the outer wall of the frame 39. Preferably, the outer wall of the frame 39 is an arc surface that adapts to the inner contour of the hairband 100 to improve the fit and stability when hanging.

[0076] The usage of this embodiment is as follows: When a user needs scalp massage care, the controller 16 is detachably connected to the first connecting seat 2 on the headband body. The controller 16 is electrically connected to the first electrical connecting terminal 23 through the second electrical connecting terminal 19, thereby supplying power to each vibration drive component 21, pressure detection unit 22, and flexible lamp plate 44. Subsequently, the user wears the headband 100 on their head, so that each massage component 8 fits against the scalp area. The flexible comb teeth 15 comb and guide the hair, and under the action of the reset elastic member 13, a moderately tight fit is formed. After receiving the detection signals from each pressure detection unit 22, the control module 18 calculates Pavg, σP, and η, and automatically determines the basic driving frequency f and basic driving amplitude A of the vibration drive component 21 accordingly. If necessary, it can also control each vibration drive component 21 to form a massage wave moving along the length direction according to the phase difference Δφ to achieve scanning massage. At the same time, the control module 18 can also control the flexible lamp plate 44 to output care light to perform phototherapy care on the scalp area.

[0077] During massage and phototherapy treatments, when the control module 18 determines that η is lower than the minimum coverage coefficient threshold η0, or the maximum contact pressure Pmax at a certain local detection point exceeds the safe pressure limit Plim, it can reduce the basic drive frequency f and / or the basic drive amplitude A, or stop all massage components 8 from operating. In some embodiments, the output intensity of the flexible lamp panel 44 can also be reduced or its operation stopped simultaneously to avoid continuous high-intensity treatment when the wearing condition is abnormal or the local pressure is too high. This improves the targeted nature, comfort, and safety of the treatment.

[0078] After the treatment is complete, the user can detach the controller 16 from the first connector 2 on the headband body and install it onto the second connector 31 on the makeup mirror 26. After being installed on the second connector 31, the controller 16 is electrically connected to the third electrical connector 33, allowing it to be charged via the power input terminal 32 through the third electrical connector 33. Simultaneously, the headband 100 can be hung on the headband suspension part 40 of the makeup mirror 26 for storage, achieving integrated use of massage treatment, light therapy treatment, charging, and storage.

[0079] The working principle of the vibration drive 21 driving the floating mounting base 9 to move is as follows: In this embodiment, the vibration drive 21 is a linear vibration motor, which is disposed between the skin-fitting mounting frame 7 and the floating mounting base 9, or its stator is fixed on the skin-fitting mounting frame 7 and its mover is connected to the floating mounting base 9 for transmission. When the linear vibration motor is powered on, it outputs a periodic linear vibration force along a preset direction and transmits the vibration force to the floating mounting base 9, causing the floating mounting base 9 to move back and forth relative to the skin-fitting mounting frame 7. Since the elastic comb 10 is disposed on the floating mounting base 9, when the floating mounting base 9 moves, it can synchronously drive the elastic comb 10 and the flexible comb 15 to move relative to the scalp, thereby forming a tangential back and forth movement and / or a normal micro-vibration displacement, which generates a rubbing mechanical stimulation to the scalp to achieve the effect of scalp massage and care.

[0080] In one specific embodiment, the fixed end of the linear vibration motor is mounted on the skin-fitting mounting bracket 7, and the output end is connected to the bottom or side of the floating mounting base 9. When the linear vibration motor is working, its output end performs high-frequency, short-stroke reciprocating motion along the motor axis, directly pushing the floating mounting base 9 to move relative to the skin-fitting mounting bracket 7, thereby causing the elastic comb 10 and flexible comb 15 mounted on the floating mounting base 9 to generate normal micro-vibration displacement relative to the scalp. Furthermore, when the output axis of the linear vibration motor is inclined relative to the local tangential plane of the skin-fitting mounting bracket 7, the floating mounting base 9 can also generate a component displacement along the tangential direction of the scalp when driven, thereby causing the elastic comb 10 and flexible comb 15 to form a tangential reciprocating rubbing action on the scalp.

[0081] The working principle and effects of scalp massage and phototherapy: In this embodiment, each massage component 8, driven by the vibration drive component 21, generates tangential reciprocating displacement and / or normal micro-vibration displacement relative to the scalp through the floating mounting base, elastic comb bar 10, and flexible comb teeth 15, thereby forming a rubbing-like mechanical stimulation on the scalp. This mechanical stimulation helps improve the massage reach of the scalp area, improve the combing state, and improve the uniformity of massage coverage in the scalp area. At the same time, the flexible lamp panel 44 outputs at least one of the following care light rays to the scalp area: red light, near-infrared light, and blue light, and / or outputs LLLT low-energy laser, thereby forming a phototherapy care effect on the scalp tissue. Combined with the pressure detection unit 22 detecting the contact pressure and the control module 18 adjusting the driving frequency, driving amplitude, and phase difference, the massage intensity and contact state can be matched with the care light output state, thereby improving care comfort, care uniformity, and overall care effect.

[0082] In one exemplary embodiment, three massage components 8, three vibration actuators 21, and three pressure detection units 22 are provided, with weighting coefficients w1=w2=w3=1 for each pressure detection point and a contact determination threshold Pth=0.40. When the pressure values ​​collected by the three pressure detection units 22 are P1=0.48, P2=0.50, and P3=0.46 respectively, the average contact pressure Pavg=(0.48+0.50+0.46) / 3=0.48 can be obtained according to the formula, the pressure dispersion σP=√{[(0.48-0.48)^2+(0.50-0.48)^2+(0.46-0.48)^2] / 3}≈0.016, and the contact coverage coefficient η=(1+1+1) / 3=1. Furthermore, if we set f0=100, fmin=80, fmax=150, k1=20, and k2=200, then the basic driving frequency f≈116.8; if we set A0=0.50, Amin=0.20, Amax=1.00, Pref=0.50, and k3=1, then the basic driving amplitude A=0.48. Therefore, when each massage component 8 fits the scalp relatively evenly and provides good coverage, the control module 18 can output a relatively stable basic driving frequency and amplitude to achieve more uniform massage care.

[0083] In another exemplary embodiment, taking three pressure detection units 22 as an example, w1=w2=w3=1, Pth=0.30, minimum coverage threshold η0=0.60, and safe pressure upper limit Plim=0.75. When P1=0.15, P2=0.82, and P3=0.20 are detected, the average contact pressure Pavg=0.39, the pressure dispersion σP≈0.305, the contact coverage coefficient η≈0.333, and the maximum contact pressure value Pmax=0.82. Since η<η0 and Pmax>Plim at this time, it indicates that there is insufficient contact and excessive local pressure between the massage component 8 and the scalp. The control module 18 can trigger a safety control strategy to reduce the basic drive frequency f and / or the basic drive amplitude A, or stop all massage components 8 from working. In some embodiments, the output intensity of the flexible lamp panel 44 can also be reduced or its operation can be stopped at the same time to avoid continuous high-intensity massage and phototherapy care under conditions of wear misalignment, local pressure, or abnormal fit.
