Description

Technical Field

[0001] This invention relates to the field of head massage equipment technology, and in particular to a scalp stretching massage device and its stretching massage method. Background Technology

[0002] In modern society, the fast pace of work and high levels of mental stress, coupled with factors such as prolonged desk work with the head down, irregular sleep patterns, and frequent tight hair binding, cause the galea aponeurotica to be in a state of continuous contraction and tension for a long time. This can easily lead to problems such as scalp stiffness, scalp fascia adhesions, and soreness and tightness around the skull. Long-term scalp tension can also compress subcutaneous capillaries, causing insufficient blood and oxygen supply to hair follicles, resulting in malnutrition of hair follicles. This can then induce problems such as abnormal scalp oil production, increased dandruff, telogen effluvium, and receding hairline. As a result, the number of people with sub-healthy scalp and hair loss is increasing year by year.

[0003] Existing head massage techniques can be broadly categorized into two types: Type 1 involves manual scalp massage, using techniques such as lifting and kneading to relax the scalp. The intensity and location can be flexibly adjusted. However, this method is primarily manual, time-consuming, and laborious, making it unsuitable for sustained daily self-care. Type 2 utilizes head massage devices. Existing devices often employ electrical stimulation or ultrasound to stimulate the scalp. The actual stimulation and massage effect are relatively weak, and the fixed, monotonous massage techniques fail to replicate the feel of a human hand massage, resulting in a poor overall head massage experience and unsatisfactory results. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a scalp stretching massage device and a stretching massage method thereof to eliminate or improve one or more defects existing in the prior art.

[0005] One aspect of the present invention provides a scalp stretching and massage device, comprising a headpiece and at least one massage module, wherein the massage module is fixedly or detachably installed within the headpiece; wherein the massage module includes a stretching drive assembly, a massage head support, and a massage head; the stretching drive assembly has a fixed end and an actuating end, the fixed end of the stretching drive assembly is fixedly disposed within the massage module, the actuating end of the stretching drive assembly is connected to the massage head support, the massage head is fixedly or detachably installed at one end of the massage head support opposite to the headpiece, and the end of the massage head forms a scalp pressing portion protruding from the inner wall of the headpiece; the stretching drive assembly is used to drive the massage head support and the massage head to perform curved surface movements within a set range, so as to stretch the scalp in the corresponding area; the trajectory of the curved surface movement is adapted to the outer surface contour of the scalp in the corresponding area of ​​the massage module.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this invention are used to explain the invention, but are not intended to limit the invention.

[0040] It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the invention are shown in the accompanying drawings, while other details that are not closely related to the invention are omitted.

[0041] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, element, step, or component, but does not exclude the presence or addition of one or more other features, elements, steps, or components.

[0042] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection involving an intermediary.

[0043] In the following description, embodiments of the invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0044] To address the limitations of existing head massage devices in terms of their limited massage effect on the head, limited stimulation of the scalp, and inability to realistically simulate human hand massage techniques, resulting in poor massage effectiveness and a subpar user experience, this invention provides a scalp stretching massage device and its stretching massage method. Unlike existing technologies that stimulate the scalp through electrical stimulation or ultrasound, the scalp stretching massage device of this invention directly stretches the scalp, effectively stimulating it and enhancing the massage effect. Furthermore, this scalp stretching massage device can realistically simulate the massage sensation of human hand massage, further improving the user experience and overall head massage effect.

[0045] On one hand, embodiments of the present invention provide a scalp stretching and massage device, such as Figures 1 to 3 As shown, the scalp stretching and massage device includes a headband body 1 and at least one massage module 2, wherein the massage module 2 is fixedly or detachably installed within the headband body 1. The headband body 1 includes a helmet shell 11 and an elastic adjustment strap 12. The helmet shell 11 can be a one-piece helmet that roughly conforms to the shape of the human head, or it can be a split helmet with upper and lower parts. The headband body 1 serves as the supporting structure for the massage module, adapting to the irregular spherical shape of the head for easy daily wear.

[0046] The elastic adjustment strap 12 is used for fine-tuning after wearing to fit different users' head circumference sizes, which helps improve the stability and applicability of the headband 1 when worn. The massage module 2 can be flexibly installed inside the headband 1. By adjusting its number and position, it can adapt to different usage scenarios, improving flexibility. For example, if only the top of the head needs massage, installing the massage module 2 in the top area of ​​the headband 1 can meet the massage needs of the top of the head; if only the side of the head needs massage, installing the massage module 2 in the corresponding side area of ​​the headband 1 is sufficient. Based on actual usage scenarios and needs, the installation position of the massage module 2 inside the headband 1 can be flexibly adjusted to meet the usage needs of different scenarios, improving the applicability of this scalp stretching massage device to different scenarios.

[0047] Among them, such as Figure 6 and Figure 7As shown, the massage module 2 includes a stretching drive assembly 21, a massage head support 22, and a massage head 23. The stretching drive assembly 21 has a fixed end and an actuating end. The fixed end of the stretching drive assembly 21 is fixedly disposed within the massage module 2, and the actuating end of the stretching drive assembly 21 is connected to the massage head support 22 for driving the massage head support 22 to move. The massage head 23 is fixedly or detachably mounted on one end of the massage head support 22 away from the headwear body 1. The end of the massage head 23 forms a scalp pressing part 231, which protrudes from the inner wall of the headwear body 1 for contacting the scalp surface.

[0048] The stretching drive component 21 is used to drive the massage head support 22 and the massage head 23 to perform curved surface movements within a set range, thereby displacing the scalp in the corresponding area. The trajectory of the curved surface movement is adapted to the contour of the outer surface of the scalp in the corresponding area of ​​the massage module 2, so that the massage head 23 can maintain close contact with the scalp during the stretching movement, which is beneficial to improving the stimulation and stretching effect on the scalp and enhancing the overall massage effect of the head. After the massage head 23 presses and adheres to the scalp, it performs curved surface movements along the scalp surface, which can also realistically simulate the stretching and kneading feeling when massaging the scalp with the hand. The curved surface movement of the massage head 23 can also make the pressure applied to the scalp during the stretching process evenly distributed, avoiding the pressure from fluctuating during the stretching process.

[0049] In the above embodiments, the massage module 2 is provided with a stretching drive component 21, which is used to drive the massage head support 22 and the massage head 23 to perform curved surface movements. By stretching the scalp, effective stimulation of the scalp can be achieved, improving the head massage effect. The curved surface movement trajectory of the massage head support 22 can improve the stability of the massage head's fit with the scalp, thereby improving the scalp stretching effect. The scalp pressing part provided at the end of the massage head can fit closely with the scalp and apply precise pressure, which can stably drive the scalp in the target area to produce orderly displacement, improve problems such as stretching slippage and force failure, further enhance the scalp stretching stimulation effect, and replicate the massage feel of human hand stretching and kneading.

[0050] The spatial movement direction of the massage module will be specifically described in conjunction with the device structure of the embodiments of the present invention, such as... Figure 3 , Figure 4 and Figure 5As shown. After the massage module 2 is assembled onto the headpiece 1, an independent three-dimensional spatial coordinate system is constructed with its installation position as the origin. The X-axis of the massage module 2 extends laterally along the human head, analogous to the extension direction of latitude lines on a globe; the Y-axis extends longitudinally along the human head, analogous to the extension direction of longitude lines on a globe; and the Z-axis is set perpendicular to the scalp surface to represent the distance change in the scalp thickness direction. The X, Y, and Z axes are mutually perpendicular and work together to form a complete three-dimensional spatial coordinate system. During operation, the stretching drive component 21 can break down the complex curved surface motion into three independent axial movements and precisely control each. Through the coordinated movement of these three axes, continuous curved surface motion of the massage head conforming to the contour of the scalp is ultimately achieved. Based on the above three-dimensional motion control logic, the stretching drive component 21 of this invention can adopt various structural embodiments to realize the curved surface stretching motion of the massage head support 22 and the massage head 23. Specific implementation methods are as follows: In a first embodiment of the stretching drive assembly 21, the stretching drive assembly 21 can achieve X-axis and Y-axis position control through two linear drive assemblies, and Z-axis position control through an arc-shaped slide.

[0051] like Figure 7 As shown, the stretching drive assembly 21 includes a base plate 211, a first linear drive assembly 212, and a second linear drive assembly 213. The first linear drive assembly 212 and the second linear drive assembly 213 are fixedly mounted on the base plate 211, and the linear movement directions of the two linear drive assemblies intersect each other. The two linear drive assemblies are used to drive the massage head 23 to reciprocate in different directions in time intervals to simulate the kneading and stretching in different directions during hand massage. Optionally, the first linear drive assembly 212 and the second linear drive assembly 213 can be arranged perpendicularly to each other on the base plate 211 to drive the massage head 23 to move along the X and Y directions; similarly, the first linear drive assembly 212 and the second linear drive assembly 213 can be arranged intersectingly on the base plate 211 to drive the massage head 23 to move in different directions.

[0052] In some embodiments, such as Figures 8 to 11 As shown, a first groove 211-1 and a second groove 211-2 are formed on the substrate 211, and a sliding limit member 221 is formed at the bottom of the massage head bracket 22. The sliding limit member 221 is assembled to slide in the first groove 211-1 or the second groove 211-2.

[0053] Furthermore, such as Figure 11As shown, the sliding limiting member 221 is located at the bottom of the massage head support 22. Both the first slide groove 211-1 and the second slide groove 211-2 are arc-shaped slide grooves. One end of the sliding limiting member 221 is fixedly connected to the massage head support 22, and the other end slides against the inner wall of either the first slide groove 211-1 or the second slide groove 211-2. The first slide groove 211-1 and the second slide groove 211-2 are configured as T-shaped grooves or dovetail grooves that match the sliding limiting member 221. These structures confine the sliding limiting member 221 within the first slide groove 211-1 or the second slide groove 211-2 during movement, preventing the massage head support 22 from detaching from the base plate due to force during movement. This improves the stability of the massage head support 22 during curved surface movement. The aforementioned arc-shaped slide groove is a concave groove that is deeper in the middle and shallower at both ends along its length. The bottom surface of the groove has an arc-shaped structure, adapting to the arc-shaped contour of the head surface. The arc-shaped groove can restrict the sliding limiter 221 at the bottom of the massage head support 22 within the groove, so that the massage head support 22 can adjust its Z-direction position along the arc-shaped bottom surface of the arc-shaped groove during the driving process. Including but not limited to this, the first groove 211-1 and the second groove 211-2 can also be set as planar grooves to guide the massage head support 22 to move along the X or Y direction.

[0054] The aforementioned linear drive assembly and slide structure, through coordinated control and overall cooperation in the X, Y, and Z directions, can achieve stable control of the curved surface motion of the massage head support 22 and the massage head 23.

[0055] Furthermore, such as Figure 7 and Figure 16 As shown, the sidewall of the massage head bracket 22 facing the first linear drive assembly 212 has a first insertion groove 222, and the sidewall of the massage head bracket 22 facing the second linear drive assembly 213 has a second insertion groove 223. The first working end 212-1 and the second working end 213-1 are configured as hinge joint structures for hinged to the corresponding insertion grooves respectively.

[0056] During the overall transmission process, the linear drive component is a fixed installation structure, and its drive output direction remains constant. Meanwhile, during the curved surface movement, the overall posture angle of the massage head support 22 adaptively adjusts in real time according to the curvature of the scalp surface, always maintaining a tangential, close-fitting posture with the scalp surface. To accommodate the motion deviation between the fixed-direction drive output and the dynamically changing support posture, this invention sets the working end of the linear drive component and the massage head support as a hinged connection structure. Through the angle adaptive compensation capability of the hinge structure, motion interference is eliminated, ensuring smooth and stable drive transmission, allowing the massage head to continuously conform to the scalp to complete the curved surface stretching action.

[0057] Furthermore, considering the reversal process between the X and Y directions during the stretching process, such as Figure 16 As shown, the first insertion slot 222 has a first opening 222-1 along the driving direction of the second linear drive assembly 213, so that while the second linear drive assembly 213 drives the massage head bracket 22 to move along the second slide groove 211-2, the first working end 212-1 of the first linear drive assembly 212 can automatically separate from the first opening 222-1 and the first insertion slot 222. The second insertion slot 223 has a second opening 223-1 along the driving direction of the first linear drive assembly 212, so that while the first linear drive assembly 212 drives the massage head bracket 22 to move along the first slide groove 211-1, the second working end 213-1 of the second linear drive assembly 213 can automatically separate from the second opening 223-1 and the second insertion slot 223. Through the mutual cooperation of the two insertion slots with the corresponding linear drive assemblies, the arc-shaped motion drive and automatic reversing function of the massage head bracket 22 can be realized, eliminating the need for a complex reversing mechanism and simplifying the internal structure of the stretch drive assembly 21.

[0058] When the first linear drive assembly 212 is working, the working end of the first linear drive assembly 212 is hinged to the massage head support 22 through the first insertion slot 222, and the sliding limit member 221 is located in the first slide groove 211-1. At this time, the working end of the second linear drive assembly 213 is separated from the massage head support 22. The first linear drive assembly 212 is used to drive the massage head support 22 to move along the arc of the extension direction of the first slide groove 211-1. After reversing, the working end of the second linear drive assembly 213 is hinged to the massage head support 22 through the second insertion slot 223, and the sliding limit member 221 is located in the second slide groove 211-2. At this time, the working end of the first linear drive assembly 212 is separated from the massage head support 22 to drive the massage head support 22 to move.

[0059] The active end of the linear drive component and the side of the massage head bracket 22 are configured as a separable hinge structure. The active end can be configured as a cylindrical or spherical structure to adapt to the angle changes during the curved surface movement. The corresponding insertion groove on the massage head bracket 22 can be configured as a cylindrical groove with an opening to adapt to the insertion, separation and hinge functions of the active end.

[0060] like Figure 9As shown, the first proximal position 211-11 is located at one end of the length of the first slide groove 211-1 near the first linear drive assembly 212, and the other end is located at the first distal position 211-12; the second proximal position 211-21 is located at one end of the length of the second slide groove 211-2 near the second linear drive assembly 213, and the other end is located at the second distal position 211-22; and the position where the first slide groove 211-1 and the second slide groove 211-2 intersect is the reversing position 211-30.

[0061] Taking the change of motion direction from Y to X as an example: After the change of direction begins, the second working end 213-1 of the second linear drive component 213 first retracts, driving the massage head bracket 22 to move towards the second proximal position 211-21; after the massage head bracket 22 is in place, the first working end 212-1 of the first linear drive component 212 extends outward, and the first working end 212-1 corresponds to the position of the first opening 222-1 on the first insertion slot 222; the extension of the second working end 213-1 drives the massage head bracket 22 to move from the second proximal position 211-21 to the reversing position 211-30. During the movement of the massage head bracket 22, the first working end 213-1... End 212-1 automatically inserts into the first insertion slot 222 of the massage head bracket 22 through the first opening 222-1; the first linear drive assembly 212 drives the massage head bracket 22 to move from the reversing position 211-30 to the first distal position 211-12. During the movement, the second working end 213-1 of the second linear drive assembly 213 automatically disengages from the inside of the second insertion slot 223; after the massage head bracket 22 is in place, the second working end 213-1 retracts to the second proximal position 211-21 to avoid obstructing the massage head bracket 22; the first linear drive assembly 212 drives the massage head bracket 22 to move along the first sliding groove 211-1, and the reversal is completed. The steps for reversing from the X direction to the Y direction are the same.

[0062] The above-mentioned reversing method uses two sets of linear drive components to cooperate in a preset timing sequence to realize the automatic insertion and separation of the drive end and the insertion slot at the reversing position, and completes the power transfer and movement direction switching of the massage head bracket 22 between the first slide groove 211-1 and the second slide groove 211-2. It does not require complex reversing components such as clutches and gears, and the reversing process is fully automated with simple control logic. With the help of the arc-shaped slide groove to constrain the movement path, the power switching is smooth, the mechanical impact and vibration are small, and the massage action transition is gentle. The internal components are few and the structure is compact and simple, which helps to reduce the overall volume of the massage module 2.

[0063] Furthermore, such as Figure 17As shown, the first linear drive component 212 and the second linear drive component 213 of the present invention can be implemented using a linear motor, an electric cylinder, or a miniature lead screw and nut structure to achieve linear drive. Both types of drive structures are compact and highly integrated. While meeting the requirements of high-precision linear drive and stable reciprocating transmission, they can effectively reduce the assembly space of the drive components, avoid occupying too much structural space inside the massage module 2, and facilitate the overall miniaturization and lightweight design of the device, improving the integration and wearability of the equipment.

[0064] In some embodiments, the massage head 23 can be made of flexible materials such as silicone or rubber, enabling the scalp pressing part at the end of the massage head to have Z-axis elastic deformation capability when in contact with the scalp. This allows it to adaptively adapt to the surface differences of different areas of the human head, ensuring a close fit with each part of the scalp. During the curved stretching motion, the arc-shaped groove mainly realizes the large Z-axis displacement adjustment corresponding to the overall arc contour of the scalp, while the Z-axis elastic deformation of the massage head itself can compensate for and adapt to the slight Z-axis height deviations of the scalp in real time, and adaptively fine-tune the fitting posture through force compression. Through the combination of large stroke adjustment of the mechanical structure and micro-deformation compensation of the flexible material, the scalp pressing part of the massage head 23 can always be closely in contact with the irregular scalp surface, eliminating gaps throughout the process and effectively avoiding problems such as stretching slippage, displacement, and detachment during the massage, thus continuously ensuring a stable and effective scalp stretching massage effect.

[0065] Furthermore, the outer shell of the massage module 2 can be fitted with a silicone protective sleeve to completely enclose and protect the outer surface of the massage module 2. During the displacement of the massage head 23 and the massage head support 22 relative to the substrate, the silicone protective sleeve, due to its flexible and stretchable material properties, elastically deforms as the massage head 23 moves. The silicone protective sleeve on the massage module 2 prevents a rigid protective sleeve from interfering with the movement of the massage head and also prevents hair from entering the interior through gaps, thus improving safety.

[0066] In a second embodiment of the stretching drive assembly 21, the scalp stretching massage device further includes a sandwich airbag 41 and an air pressure regulating assembly 42. The air pressure regulating assembly 42 is connected to the sandwich airbag 41 and is used to maintain the internal pressure of the sandwich airbag 41 at a set value. The massage module 2 completes three-axis position adjustment through the linear drive assembly and the sandwich airbag 41 to achieve a complete scalp surface stretching motion. Specifically, in this embodiment, two linear drive assemblies drive the massage head 23 to complete precise position fine-tuning and reciprocating sliding motion in the X and Y directions, which can simulate the action of rubbing and pulling the scalp by hand. The overall displacement and pressing adjustment in the Z direction is completely completed independently by the sandwich airbag 41. Relying on the flexible deformation of the airbag, it adaptively adapts to the concave and convex contours of different users' scalps. The three axes cooperate with each other to achieve a curved surface following motion effect that conforms to the contour of the scalp, ensuring that the massage head and the scalp are fully in contact, and improving the range of action and massage comfort of the scalp stretching massage. The air pressure regulating component 42 can dynamically regulate the air pressure inside the airbag, so that the massage module 2 can press the scalp with a set pressure, which can ensure the effective stretching force of the scalp, while avoiding local pressure pain caused by hard contact, thus balancing the effectiveness of massage and the safety of use.

[0067] As one possible approach, such as Figure 12 As shown, the headband body 1 has an inner layer and an outer layer, and the interlayer airbag 41 is disposed between the inner layer and the outer layer of the headband body 1. The inner layer is provided with several windows, and the interlayer airbag 41 is provided with a module mounting part at the position corresponding to the window for mounting the massage module 2. In this solution, the interlayer airbag 41 is integrated on the headband body 1. By adjusting the internal air pressure of one interlayer airbag 41, the pressing pressure of multiple massage modules 2 can be uniformly controlled, realizing a Z-axis overall adjustment mode of single airbag adjusting multiple modules. This structure can adapt to differences in head shape and automatically ensure that the massage modules 2 at each position apply uniform pressure to the scalp, avoiding excessive local pressure or inadequate contact. At the same time, there is no need to configure a separate Z-axis drive element for each group of massage modules, which greatly simplifies the internal pipeline and mechanical structure of the scalp stretching massage device, reduces the assembly complexity of the whole machine, facilitates the miniaturization of the device, and also improves the response consistency of multiple modules synchronously pressing.

[0068] As another implementation method, such as Figures 13 to 15 As shown, the massage module 2 includes a fixed base 24 and a floating base 25, and the stretching drive assembly 21 is disposed on the floating base 25; the interlayer airbag 41 is disposed between the fixed base 24 and the floating base 25 and is connected to both the fixed base 24 and the floating base 25. The interlayer airbag 41 is configured to expand or contract along the line connecting the fixed base 24 and the floating base 25, that is, to adjust up and down along the Z-axis direction, so as to adjust the pressure of the massage head 23 on the scalp or compensate for the displacement of the massage head 23 in the direction perpendicular to the scalp.

[0069] In this embodiment, different massage modules 2 are independently configured with interlayer airbags 41 and air pressure adjustment components 42, enabling independent control and differentiated adjustment of the pressure intensity at each massage point. Addressing user scenarios involving uneven scalp contours, varying scalp tolerance in different areas, and varying degrees of localized soreness and fatigue, the pressure intensity of different massage areas such as the forehead, top of the head, back of the head, and sides can be adjusted individually to precisely meet the massage needs of different scalp areas. This structure, employing independent air pressure adjustment, enhances the flexibility and targeting of the device's massage, enabling diverse massage modes such as zoned gentle kneading, zoned heavy pressure, and localized targeted pressure, improving issues such as insufficient local pressure and discomfort caused by localized compression. Simultaneously, the modular embedded structure is compact and highly independent, without interfering with the three-axis motion functions of each module. While ensuring the basic massage effects of scalp curvature stretching and reciprocating kneading, it optimizes the personalized massage experience, adapting to more users' head shape differences and massage preferences, thus improving device compatibility and user comfort.

[0070] Furthermore, the air pressure regulating component 42 includes an air pump and an air tube. The output end of the air pump is connected to the input port of the interlayer airbag 41 through the air tube, and is used to automatically adjust the air pressure inside the interlayer airbag, thereby adjusting the expansion position of the massage module in the Z direction. Specifically, when the air pressure increases, the interlayer airbag 41 expands and its thickness increases, the massage module protrudes from the inner wall of the headband body 1 and gets closer to the scalp surface, or the pressure on the scalp increases; conversely, when the air pressure decreases, the interlayer airbag 41 contracts and its thickness decreases, the massage module moves away from the scalp surface, or the pressure on the scalp decreases.

[0071] In this embodiment, the X and Y direction motion adjustments are mainly achieved through the stretching drive component, while the Z direction motion adjustment perpendicular to the scalp is achieved through the interlayer airbag 41. In the Z direction, due to the flow characteristics of the gas inside the airbag, the massage modules 2 installed at different locations on the interlayer airbag 41 apply equal pressure to the scalp. By adjusting the air pressure, the pressure of multiple massage modules can be uniformly adjusted, ensuring that each massage module 2 applies equal pressure to the scalp, thus avoiding local overstretching or understretching.

[0072] In some embodiments, the stretching drive component 21 can also be configured with the same arc-shaped groove and sliding limiter structure as in the first embodiment, so as to control and adjust the Z-axis movement through the coordinated cooperation of the arc-shaped groove and the interlayer airbag 41. Specifically, the arc-shaped groove is used to achieve rigid adjustment of the Z-axis position over a large range while maintaining the stability of the overall structure; the interlayer airbag 41 performs flexible adjustment of the Z-axis position in a localized small range, which can ensure stable fit to irregular scalp while ensuring Z-axis support, thus improving the scalp massage effect.

[0073] In a third embodiment of the stretching drive assembly, the stretching drive assembly 21 integrates a three-dimensional adjustment mechanism that can simultaneously achieve independent control in the X, Y, and Z directions, and realizes full-space freedom motion control of the massage head through a three-axis stacked linear drive structure.

[0074] The stretching drive assembly 21 includes a mounting base, a first linear drive assembly 212, a second linear drive assembly 213, and a third linear drive assembly. The mounting base is fixedly or detachably mounted on the inner wall of the headpiece body 1. The fixed end of the first linear drive assembly 212 is fixedly connected to the mounting base. The fixed end of the second linear drive assembly 213 is fixedly connected to the movable end of the first linear drive assembly 212. The fixed end of the third linear drive assembly is fixedly connected to the movable end of the second linear drive assembly 213, and the movable end of the third linear drive assembly is fixedly connected to the massage head support 22. The linear movement directions of the first linear drive assembly 212, the second linear drive assembly 213, and the third linear drive assembly are configured to be perpendicular to each other in pairs. By stacking these three linear drive assemblies in the Z-axis, motion control in three-dimensional space can be achieved simultaneously, allowing for more flexible adjustment of the spatial position of the massage head support 22 and the massage head 23.

[0075] The three linear drive components adopt a vertically stacked integrated structure design, which can simultaneously complete independent position adjustment in the X, Y, and Z spatial directions without the need for additional reversing transmission structures, resulting in higher structural integration and a simpler transmission path. At the same time, this structural design significantly improves the flexibility and response speed of the massage head's 23 curved surface movement, enabling more precise and diverse spatial trajectory motion control. It can accurately adapt to the curved shape and stretching needs of different areas of the scalp, effectively achieving precise stretching of various parts of the scalp.

[0076] In some embodiments, such as Figure 6 As shown, the massage head 23 also includes a pressure sensor 232, which is integrated on the scalp pressing part 231 and is used to obtain the pressure parameters between the scalp and the massage head 23.

[0077] The scalp stretching massage device can adjust the movement state of the massage head based on the pressure parameters obtained by the pressure sensor 232. For example, when the pressure sensor 232 detects that the pressure parameter between the massage module 2 and the scalp is greater than the preset pressure range, the scalp stretching massage device can reduce the stretching stroke or reduce the stretching speed accordingly to avoid overstretching and damaging the scalp. When the pressure parameter between the massage module 2 and the scalp is detected to be less than the preset pressure range, the scalp stretching massage device can increase the stretching stroke or speed up the stretching to maintain effective stimulation of the scalp.

[0078] The scalp stretching massage device can also adjust the air pressure parameters inside the interlayer airbag 41 based on the pressure parameters obtained by the pressure sensor 232, so that the pressure of the massage module 2 installed on the interlayer airbag 41 on the scalp is kept within a preset range, so as to ensure that the scalp pressing part is in close contact with the scalp.

[0079] In some embodiments, the stretching drive assembly 21 further includes a position sensor 216 for monitoring the position of the working ends of the two linear drive assemblies or the position of the massage head support 22, so as to accurately sense the movement position of the massage head support 22. Figure 14 As shown, the position sensor 216 includes: a sensing slider 216-1, a connecting rod 216-2, and a sensing grating 216-3; the sensing grating 216-3 is mounted on the substrate 211 and has a groove along its length; the sensing slider 216-1 is slidably mounted inside the groove, one end of the connecting rod 216-2 is connected to the sensing slider 216-1, and the other end is connected to the movable structure of the second linear drive assembly 213.

[0080] A first position sensor 216-A and a second position sensor 216-B can be set inside the same massage module 2. The first position sensor 216-A is set side by side with the first linear drive component 212, and the sensing slider 216-1 of the first position sensor 216-A is connected to the movable structure of the first linear drive component 212 through the connecting rod 216-2, so that the first linear drive component 212 can move synchronously to drive the sensing slider 216-1 to move, thereby obtaining the motion drive parameters of the first linear drive component 212. The set position sensor 216 can accurately obtain the motion direction of the massage module 2, and can also obtain parameters such as the position, speed and stroke of the massage head bracket, thereby providing data support for the intelligent control and adjustment control of the curved surface motion of the stretch drive component 21.

[0081] Furthermore, the position sensor 216 is also used to calculate and identify the position state of the massage head support 22. By monitoring whether the sliding limit member 221 of the massage head support 22 is at the intersection of the first slide groove 211-1 and the second slide groove 211-2, it can determine whether the stretching drive assembly 21 can perform a reversing operation, thereby improving the intelligence level of the motion control of the massage module 2 and enabling the components to cooperate.

[0082] In some embodiments, a plurality of mounting seats are provided on the inner wall of the head-mounted body 1, and each mounting seat is arranged on the inner wall of the head-mounted body along the massage acupoints of the human head; the massage module 2 is provided with a mounting head on the side near the head-mounted body 1, the side of the mounting seat is provided with a limiting slot, the mounting head is provided with a pop-out limiting block, the limiting slot and the limiting block are mutually adapted, and the massage module 2 and the head-mounted body 1 are detachably connected through a snap-fit ​​structure, which facilitates flexible adjustment during use, and the modular design improves the flexibility of daily use.

[0083] Furthermore, the side of the mounting base is provided with at least two limiting slots, and each limiting slot is arranged circumferentially along the side of the mounting base; the limiting block of the mounting head is used to engage with any of the limiting slots on the mounting base to limit the installation angle of the massage module. By selecting the limiting slots that the mounting base engages with, the massage module can be installed at different arrangement angles, thereby achieving stretching in the up, down, left, and right directions, as well as stretching in any tilt direction, to achieve stretching massage of the scalp in different directions, which helps to improve the flexibility and versatility of the scalp stretching massage device.

[0084] In some embodiments, the mounting head is provided with a first circuit interface 26, and the mounting base is provided with a second circuit interface. The first circuit interface 26 and the second circuit interface are configured to match each other. The headband body 1 is connected to the massage module 2 through a circuit structure for power supply and data transmission. The structure eliminates the need for complex cabling, improving overall structural simplicity. Using a circuit structure for connection also facilitates quick replacement of the massage module 2. Hardware installation and circuit connection are implemented simultaneously, simplifying daily installation operations. The first circuit interface 26 can be a common USB interface or a Type-C interface to achieve circuit connection and data interaction.

[0085] As one possible approach, such as Figure 15 As shown, the first circuit interface 26 can also be set on the mounting base 24 of the massage module 2 to realize the electrical connection to the headband body 1.

[0086] Furthermore, such as Figure 2As shown, the headband 1 can also integrate a control module 5 and a power module 6. The control module 5 and the power module 6 can establish electrical connections with each massage module 2 through built-in circuit interfaces. The power module 6 provides stable power to the electrical structure of the whole machine, ensuring the stable operation of electronic components such as the linear drive component, the air pressure regulation component 42, and the sensing component. The control module 5 can realize independent control and coordinated scheduling of each massage module 2 through circuit interaction, complete the issuance of motion parameter commands, the acquisition of working status data and the real-time data transmission, and realize precise closed-loop control of parameters such as massage trajectory, stretching speed and pressing pressure, effectively improving the automation level and overall working stability of the device.

[0087] In some embodiments, the scalp stretching massage device further includes a scalp wrinkle detection module 3. The number of scalp wrinkle detection modules 3 installed inside the headwear body 1 can be flexibly increased or decreased, and the assembly position can be adaptively adjusted to meet the wrinkle detection needs in different massage scenarios. The scalp wrinkle detection module 3 includes at least one elastic probe 31 disposed on the massage module 2, such as... Figure 6 As shown, the elastic probe 31 is mounted on the fixing component of the massage module 2. The end of the elastic probe 31 is approximately flush with the end of the massage head 23. The end of the elastic probe 31 has an electroplated coating for contact with the scalp, used to monitor the degree of scalp wrinkles in the corresponding area of ​​the massage module 2. During the massage, the scalp wrinkle detection module 3 can collect data on the degree of scalp wrinkles in each massage area in real time, using this as a basis for closed-loop control. The device can dynamically correct the stretching speed and stretching direction of each massage module according to the real-time scalp wrinkle state of different areas, adaptively matching the tightness of the scalp in each area, so that the degree of wrinkles in adjacent and same-side scalp areas remains consistent, effectively avoiding the defects of excessive or insufficient stretching in some areas, ensuring the uniformity and stability of the overall massage, and highly replicating the real large-area, fine hand kneading and stretching experience.

[0088] The elastic probe 31 can adopt a microneedle structure design smaller than the hair follicle spacing, which can be directly inserted into the gap between hair roots to separate hair strands. It can reach the epidermal layer of the scalp without shaving, forming a stable physical contact with the scalp and effectively eliminating signal interference caused by hair obstruction. The main body of the elastic probe 31 can be made of conductive metals such as gold, silver, and copper, and the end electrocoating is made of highly conductive materials such as graphene and PEDOT. It can form a stable electrode-electrolyte interface with the scalp, converting scalp wrinkle deformation into changes in resistance and capacitance. The contact impedance density is selected within an appropriate range (optionally ≤0.03 kΩ·cm²) to accurately capture the deformation signal of local scalp wrinkles.

[0089] Meanwhile, the elastic probe 31 is also equipped with a spring buffer structure, which can adapt to the detection needs of different areas of the scalp and avoid stinging sensations during wearing and detection, ensuring user comfort. It is understandable that the control parameters output by the stretching drive component 21 during actual stretching are not equal to the actual stretching parameters of the scalp. The actual stretching effect of the scalp is also affected by factors such as the fit of the massage head and the tightness of the scalp. The scalp wrinkle detection module 3 can obtain the actual massage effect of the massage module on the scalp. When the degree of scalp wrinkles exceeds the upper limit, such as when there are many wrinkles, the scalp wrinkle detection module 3 sends an alarm signal to control the massage module 2 to reverse stretching or stop stretching.

[0090] In some embodiments, such as Figure 3 As shown, the scalp wrinkle detection module 3 includes at least one camera module 32, which is mounted on the inner wall of the headpiece 1 to acquire scalp images at corresponding locations. The camera module 32 is equipped with a multi-magnification optical lens group (selectable from 50-200x) to penetrate the gaps in the hair and capture images of the scalp at predetermined locations. The camera module also includes structures such as polarizers and specific wavelength filters to eliminate scalp oil reflection, allowing for the identification of scalp wrinkle distribution through the captured images. The camera module 32 can also be used to directly detect blood flow on the scalp surface to adjust the stretching and pressing pressure. For example, if the camera module 32 detects localized redness and blood pooling on a specific area of ​​the scalp due to excessive stretching or pressing, it can promptly adjust the pressure on the scalp or reduce the stretching stroke to avoid excessive massage and scalp damage, thus improving the safety and user experience of the scalp stretching massage device.

[0091] In some embodiments, the scalp stretching massage device further includes a light module 7, such as Figure 6 As shown, the light module 7 is located on the side of the massage module 2 away from the headwear body. The light module 7 is used to output light of a set wavelength. Relying on the photobiological regulation effect, the light is absorbed by the scalp tissue, which improves the level of cell energy metabolism, promotes the active dilation of microvessels in the dermis of the scalp, improves the local microcirculation of the scalp, and enhances the blood oxygen supply to the tissues around the hair follicles.

[0092] The light module 7 and the massage module 2 work together to enhance the therapeutic effect of scalp massage: the mechanical stretching and kneading action generated by scalp stretching can loosen the soft tissue of the scalp and promote the passive dilation of scalp microvessels; light exposure enhances the dilation ability of microvessels at the cellular level and amplifies the blood flow improvement effect brought about by mechanical stretching. Compared with scalp stretching massage alone, the combination of the two can further improve local blood flow in the scalp.

[0093] The light module 7 and massage module 2 support multiple working modes: Mode 1 is light-first, then stretching, where light first irradiates the scalp, followed by massage to promote blood circulation; Mode 2 is stretching first, then light-first, where mechanical massage stretches the scalp, reduces light blockage by hair, and improves the penetration depth and energy uniformity of subsequent light irradiation; Mode 3 is simultaneous light-first and stretching, where massage dynamically changes the shape of the scalp, assisting light penetration into the hair follicle area and synergistically soothing the scalp. These multiple modes can be flexibly switched to adapt to different users' scalp conditions and usage habits, enhancing the user experience and therapeutic effect.

[0094] Optionally, the light module 7 is a light source adapted to photobiological regulation function, which can be red light, near-infrared light or blue light; preferably red light or near-infrared light with a wavelength of 650-660nm, and blue light is used for auxiliary irradiation of the scalp surface.

[0095] On the other hand, the present invention also provides a scalp stretching massage method, such as... Figure 18 As shown, this method is implemented using the aforementioned scalp stretching and massage device, and includes the following steps: S11. By controlling the first massage module, the scalp of the first specific area is stretched along the direction of the first arc of the scalp surface.

[0096] S12. By controlling the second massage module to stretch the scalp of the second specific area along the direction of the second arc on the scalp surface, the second massage module and the first massage module are symmetrically set relative to the top of the skull, and the direction of the second arc is opposite to the direction of the first arc; simultaneously driving the two symmetrical massage modules to work, it can realize the synchronous massage of the scalp on both sides of the head, which is conducive to balancing the blood and qi balance of the head, simultaneously unblocking the blood circulation on both sides of the head, and also makes the force on both sides of the scalp even, avoiding the situation of overstretching the scalp on one side, thereby improving the overall massage effect and optimizing the user experience.

[0097] Understandably, the aforementioned cranial vertex is the highest point on the midsagittal plane of the skull when it is in the Frankfurt plane. It is a core anatomical landmark of the head, located in the central region of the top of the head, and is close to the location of the Baihui acupoint.

[0098] Optionally, the first and second specific sites can be arranged along the distribution of acupoints on the head to directly stimulate the acupoints and enhance the massage effect.

[0099] S13. The scalp wrinkle detection module 3 monitors the degree of scalp wrinkles in the first specific area and the second specific area respectively.

[0100] S14. The stretching speed or stretching direction of the first massage module and / or the second massage module is controlled by the degree of scalp folds in the first specific part, and the stretching speed or stretching direction of the first massage module and / or the second massage module is controlled by the degree of scalp folds in the second specific part, so that the degree of scalp folds in the first specific part and the second specific part are matched.

[0101] Specifically, this device enables simultaneous stretching and massage of symmetrical acupoints on both sides. The first and second specific locations are correspondingly positioned on symmetrical acupoints on the left and right sides of the scalp, with the corresponding first and second massage modules symmetrically arranged on both sides of the headpiece 1. During operation, the two massage modules synchronously initiate stretching actions based on real-time scalp fold detection data collected by the scalp fold detection module 3, performing synchronized curved surface stretching on the identical symmetrical acupoints on both sides of the head. This control method highly simulates the simultaneous kneading and stretching of symmetrical acupoints on both sides of the head during a manual massage, ensuring balanced force and synchronized massage rhythm on both sides of the head. This not only significantly improves the overall symmetry and comfort of the head massage but also specifically addresses issues of scalp tightness and uneven force distribution, further replicating the authentic experience of a human hand massage.

[0102] The stretching direction and intensity of the massage modules on both sides can be adaptively set to be the same or different according to massage needs, adapting to diverse head massage requirements. When the stretching direction of the massage modules on both sides is the same, the stretching action of both sets of massage modules is along the Y-axis towards the top of the skull, achieving symmetrical and unidirectional traction on both sides of the head, replicating the massage technique of simultaneously lifting the scalp upwards with both hands, ensuring balanced force and synchronized rhythm on both sides of the head, effectively relieving tension in the entire scalp. When the stretching directions of the massage modules on both sides are different, one set of massage modules stretches along the Y-axis towards the top of the skull, while the other set of massage modules stretches along the X-axis laterally of the head. This combination of bidirectional staggered stretching motions increases the diversity of massage methods.

[0103] As one possible approach, the aforementioned scalp stretching massage method can also include a third, fourth, or fifth massage module. By flexibly adjusting the number of massage modules 2, the massage effect on both sides of the head can be improved. Simultaneously massaging multiple areas on both sides of the head further enhances scalp stimulation. For example, massage modules 2 can be placed in four areas—front, back, left, and right—to improve the overall massage effect and promote blood circulation. Including but not limited to this, a massage module 2 can also be placed on the top of the head to achieve comprehensive stretching stimulation. By setting multiple symmetrically arranged massage modules, a coordinated lifting of the entire head can be achieved, simulating the effect of multi-finger synchronous symmetrical massage, providing a comprehensive head massage with wider coverage and more even pressure.

[0104] In another aspect, the present invention also provides a scalp stretching and massage method, such as... Figure 19 As shown, the method implemented using the aforementioned scalp stretching and massage device includes the following steps: S21. By controlling the first massage module, the scalp of the first specific area is stretched along the direction of the first arc of the scalp surface.

[0105] S22. By controlling the second massage module, the scalp of the second specific area is stretched along the direction of the second arc on the scalp surface. The second massage module is adjacent to the first massage module, and the direction of the second arc and the direction of the first arc are both arbitrary. The arbitrary direction of the two arcs means that the direction of movement of the massage module 2 along the scalp surface can be flexibly adjusted. By adjusting the installation angle of the massage module 2 or by changing its direction, the scalp can be stretched in any direction along the scalp surface, which helps to improve the flexibility of the scalp massage method.

[0106] S23. The scalp wrinkle detection module 3 monitors the degree of scalp wrinkles in the first specific area and the second specific area respectively.

[0107] S24. The stretching speed or stretching direction of the first massage module and / or the second massage module is controlled by the degree of scalp folds in the first specific area, and the stretching speed or stretching direction of the first massage module and / or the second massage module is controlled by the degree of scalp folds in the second specific area, so that the degree of scalp folds in the first specific area and the second specific area are matched.

[0108] In this invention, the first and second massage modules, which are located adjacent to each other, work together to achieve a variety of human hand-simulated massage modes, covering multi-dimensional scalp stretching, kneading, and rubbing loosening effects. The working modes include at least: Mode 1: Two adjacent massage modules can move in opposite directions, either opening away from each other or moving towards each other. When the modules move away from each other, they can open the scalp in the middle area laterally to both sides, effectively relieving the horizontal wrinkles of the scalp and loosening the horizontal tension of the scalp. When the modules move towards each other, they can clamp and squeeze the middle scalp, kneading the subcutaneous soft tissue and promoting local subcutaneous microcirculation. This replicates the massage method of using two fingers to open the scalp laterally and then squeeze and knead it, closely matching the massage feel of a real hand.

[0109] Mode 2: The two massage modules maintain a constant distance and move synchronously along the same arc direction, which can drive the entire scalp to slide relative to the skull, fully loosening the adhesion between the scalp and fascia, achieving gentle relaxation of the scalp as a whole, without local strong tearing stress, corresponding to the gentle massage method of the palm of the hand pressing against the scalp and stroking the scalp, with a wide massage coverage and a gentle and comfortable feeling.

[0110] Mode 3: The two massage modules use mutually perpendicular intersecting motion directions. One module pulls vertically and the other pulls horizontally, forming a compound motion trajectory of oblique staggered movement. This applies a compound force of oblique shearing and stretching to the scalp in the middle, stretching the oblique wrinkles of the scalp in multiple dimensions and relieving the tension of the scalp fascia from all angles. It replicates the massage technique of human hands diagonally pulling the scalp, stretching the scalp in multiple directions for a more comprehensive massage effect.

[0111] Mode 4: The two massage modules work alternately, with one module stretching and maintaining tension on the scalp while the other remains still. This alternating cycle creates a wave-like, reciprocating pulling and relaxing effect, significantly reducing localized instantaneous stress on the scalp. The stimulation is gentle and consistently stable, suitable for the needs of sensitive scalps. It simulates the gentle massage of human fingers repeatedly stroking the scalp, gradually relieving scalp fatigue.

[0112] By flexibly combining massage modules 2, the massage modes of this scalp stretching massage device can be enriched, thus realistically simulating various massage techniques of the human hand, which helps to improve the scalp stretching massage effect and enhance the user experience. Specifically, this device can realize multi-mode intelligent collaborative stretching massage function, supports the working logic of linkage between the same side or adjacent points, and can achieve closed-loop adaptive control based on scalp fold monitoring data. The first and second specific points are set in the same or adjacent areas of the scalp. The first and second massage modules perform synchronous stretching operations in the same direction based on the real-time detection data of the scalp fold detection module 3. The two sets of massage modules synchronously pull the scalp along the same arc direction. Through the coordinated cooperation of multiple modules, the scalp coverage area of ​​a single synchronous stretch can be effectively expanded, changing the limitations of traditional single-point small-range stretching. Multi-module synchronous linkage stretching can create an overall linkage traction effect on adjacent scalp areas, making the scalp of the target massage area more consistent and evenly stressed, avoiding problems such as local stretching breaks and uneven massage areas, greatly improving the fit and overall massage of large-area scalp stretching, and significantly enhancing the massage effect and comfort of the entire scalp stretching.

[0113] As one possible approach, this scalp stretching massage method can also install a third, fourth, or fifth massage module. By flexibly adjusting the number of massage modules 2 installed, more complex and realistic massage movements can be achieved. The multiple massage modules can simulate the kneading movements of multiple fingers of a human hand, more realistically simulating the coordinated massage effect of a human hand, thus improving the scalp massage effect and user experience.

[0114] The beneficial effects that can be achieved by the scalp stretching massage device and massage method described in the embodiments of the present invention include at least the following: (1) The massage module of the scalp stretching massage device is equipped with a stretching drive component, which can drive the massage head support and massage head to perform curved surface movement, which is conducive to achieving effective stretching of deep scalp tissues and improving the overall massage effect of the scalp.

[0115] (2) The trajectory of the curved surface movement of the massage head support and the massage head during stretching is adapted to the contour of the scalp surface, which can improve the stability of the massage head and the scalp, thereby improving the scalp stretching effect; (3) The end of the massage head of the massage module is provided with a scalp pressing part, which can fit closely with the scalp and reliably drive the scalp to move, further enhancing the scalp stretching effect.

[0116] (4) The massage module is also equipped with a sliding limiter and an arc-shaped sliding groove, which can guide the massage head to perform curved surface movements and restrict the massage head support on the base plate, which helps to improve the fit between the movement trajectory of the massage head and the contour of the scalp surface.

[0117] (5) The massage head bracket is provided with a plug slot for hinged engagement with the working end of the linear drive component to avoid affecting the attitude deflection angle of the massage head bracket during the driving process of the linear drive component.

[0118] (6) The headband is equipped with a sandwich airbag, which can adjust the position of the massage module in the Z direction and also has a flexible buffer function, which is conducive to uniformly adjusting the pressure of each massage module to improve the massage effect.

[0119] (7) The scalp stretching massage device is also equipped with a scalp wrinkle detection module, which can obtain the distribution of wrinkles on the scalp surface, provide a basis for the control and adjustment of the massage module, and thus improve the massage experience.
