[0002] Combs have been widely used by people since a very long time ago. The history of combs can be traced back to more than 6000 years ago. According to the clinical view of traditional Chinese medicine, combing the head is not only a daily care behavior, but also an important means of regulating qi and blood, invigorating the brain and calming the mind by stimulating the meridians and acupoints of the head.

[0003] In the prior art, for the elderly and young people with high-intensity life and work, the increase in age or work pressure greatly increases the occurrence of neurodegenerative diseases. At present, a relatively effective relief method is a health care and physiotherapy of the nerve regulation type. However, the physiotherapy equipment using a transcranial magnetic stimulation device is large in size, complex in operation, and low in portability. Therefore, people generally need to go to a hospital or a large physiotherapy place for experience, which is very inconvenient. If the comb and the health care concept are combined together, the physiotherapy intervention can no longer be limited to hospitals and professional institutions, more people can benefit, a convenient health management method is provided for specific groups of people, the family and social pressure is relieved, and the popularization of a healthy life is promoted.

[0004] Therefore, it is necessary to provide an intelligent comb product with health care and physiotherapy effects. SUMMARY

[0037] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined invention purposes, the following will be described in detail in combination with the preferred embodiments and the accompanying drawings.

[0038] The shape, structure, module position, etc. of the intelligent comb shown in the embodiment of the present application are all schematic, and the present disclosure does not limit the shape, structure, module position, etc. of the intelligent comb.

[0039] As shown in the figure, the embodiment of the present application provides an intelligent comb, which includes a comb body 10 and comb teeth 20 arranged in an array on the comb body. Figures 1-4 It also includes a brain wave signal acquisition module 30, a data storage module 40, a multi-modal stimulation generation module 50, a control module 60, a power supply module 70, an impedance signal acquisition module 80, a user interaction module 90, a model algorithm module 100, and a networking communication module 200.

[0040]

[0041] ​The brain wave signal acquisition module 30 is arranged at the end of the comb teeth 20 or in the gap between the comb teeth 20, and is used to acquire brain wave signals and send them to the control module 60. Specifically, the comb body 10 is designed as a hollow structure for placing the control module 60, and the comb teeth 20 are also designed as a hollow structure for placing a cable for signal transmission. The cable is connected to the control module 60 and the brain wave signal acquisition module 30. The brain wave signal acquisition module 30 can be an EEG brain wave acquisition module, which includes a collection electrode and an amplifier. The electrical signal collected by the collection electrode is digitized and sent to the amplifier. The amplified data can be displayed as a voltage value sequence and transmitted to the control module 60.

[0042] The data storage module 40 is connected to the control module 60 and is used to store brain wave data and stimulation programs corresponding to the brain wave data. In an alternative embodiment, the brain wave signal acquisition module 30 detects the brain wave bioelectric signal. The brain wave data in the data storage module 40 is a data set of the brain wave bioelectric signal of a person in various states, including but not limited to sleep, wakefulness, excitement, fatigue, tension, loss, happiness, sadness, and other psychological states. The data set includes various characteristic values of brain waves such as Delta waves, Theta waves, Alpha waves, Beta waves, and Gamma waves. For each characteristic value, a plurality of stimulation programs are pre-set for the corresponding characteristic parameters, such as single-mode stimulation or multi-mode mixed stimulation.

[0043] The control module 60 is connected to the multi-modal stimulation generation module 50 and the data storage module 40, and is used to determine an initial stimulation program based on the brain wave signal and the brain wave database, and control the multi-modal stimulation generation module 60 to generate a corresponding stimulation behavior according to the initial stimulation program.

[0044] The model algorithm module 100 is connected to the networking communication module 200 and the data storage module 40, and is used to store model algorithms and update the stimulation programs corresponding to the brain wave data based on the data transmitted by the networking communication module 200. The networking communication module 200 is used for networking data transmission and upgrading the model algorithms of the model algorithm module 100. Specifically, it transmits data through wifi, Bluetooth or star flash communication protocol, and upgrades the model algorithms of the model algorithm module 100 through OTA (Over-the-Air Technology).

[0045] The intelligent comb also includes an impedance signal acquisition module 80 connected to the control module 60. The impedance signal acquisition module 80 is used to acquire skin or limb impedance signals. The control module 60 adjusts the stimulation intensity, frequency or mode of the stimulation behavior based on the impedance signal.

[0046] The control module 60 determines the initial stimulation scheme based on the brain wave signal and the brain wave database, and controls the multi-modal stimulation generation module 50 to generate corresponding stimulation behavior according to the initial stimulation scheme.

[0047] The control module 60 is usually composed of a chip module and an integrated circuit, which matches the received voltage value sequence with the voltage value sequence in the data storage module 40, determines the corresponding initial stimulation scheme, and then controls the multi-modal stimulation generation module 50 to generate corresponding stimulation behavior according to the initial stimulation scheme.

[0048] The power supply module 70 is used for power supply of the brain wave signal acquisition module 30, the data storage module 40, the multi-modal stimulation generation module 50, the control module 60, the power supply module 70, the impedance signal acquisition module 80, the user interaction module 90, the model algorithm module 100, and the networking communication module 200.

[0049] The light, sound, and vibration stimulation of the present application is realized according to the neural oscillation effect. Gamma oscillation (30-150 Hz) is a key rhythm of brain cognitive function, which plays an important role in neural networks and can enhance the effectiveness, accuracy, and selectivity of information exchange between brain regions. It is related to the following mechanisms:

[0050] a) Neuron synchronization: Gamma frequency promotes neuron network synchronization and enhances information processing efficiency;

[0051] b) Synaptic plasticity: adjusts the sensitivity of neurotransmitter receptors and affects memory and learning ability;

[0052] c) Vascular coupling: Gamma oscillation optimizes brain region blood supply through neural vascular coupling mechanism.

[0053] When external stimuli (such as light, sound, and vibration) act on the sensory system at a specific frequency (such as 40 Hz), brain neurons may synchronize with the stimulation frequency through resonance mechanism, which is called "entrainment effect". Sound stimulation can be transmitted to the cerebral cortex through the auditory nerve and mechanical vibration, light stimulation can penetrate the skull (such as near-infrared light) and activate the visual cortex or affect brain activity through non-visual light receptors, which is called neural oscillation synchronization.

[0054] The odor stimulation of the present application connects the brain limbic system through the olfactory pathway to play a stimulating role. Specifically, odor molecules are converted into neural signals by olfactory epithelial cell receptors in the nasal cavity, transmitted to the olfactory bulb through the olfactory nerve, and then bypass the thalamus to reach the amygdala (emotion center) and hippocampus (memory center). This "fast channel" allows odor to quickly trigger emotional response and memory retrieval, forming a "Proust effect".

[0055] Functional magnetic resonance imaging (fMRI) shows that linalool of lavender enhances alpha brain waves (8-13 Hz) by regulating gamma-aminobutyric acid (GABA) levels, enabling the brain to enter a relaxed and focused state, and these areas are simultaneously involved in attention regulation, which can improve memory efficiency.

[0056] Research data from Tel Aviv University in Israel shows that the efficiency of information integration between the hippocampus and the cerebral cortex of subjects receiving odor stimulation is improved. Long-term exposure to specific fragrances (such as mint, rosemary) can improve attention span by about 20%, which may have a delaying effect on cognitive decline in the elderly.

[0057] Research data from the Baltimore Longitudinal Study of Aging at the University of California, USA, and the Neuroscience Research Institute at Erwin University shows that olfactory reinforcement can significantly improve memory in the elderly (memory test scores increased by 226% after 6 months) and enhance the integrity of the left hook bundle of the brain.

[0058] Research data from plant medicine research in Austria and Germany shows that aromatherapy scents can reduce cortisol levels (stress hormone) by 15%-25% by activating the amygdala to regulate emotions, such as rose and jasmine essential oils, which can reduce emotional stress and improve depressive symptoms. Research data from Kagoshima University and Pine University in Japan shows that lavender can relieve pre-sleep stress by enhancing alpha wave activity in the brain, while improving sleep quality, with research data showing that subjects fall asleep 35% faster and deep sleep stages are extended by 25%.

[0059] Therefore, in the embodiment of the present application, the multi-modal stimulation generation module 50 includes, in addition to the light stimulation unit 51 for generating light stimulation, the sound wave stimulation unit 52 for generating sound wave stimulation, the vibration stimulation unit 53 for generating vibration, and the odor stimulation unit 54 for generating a predetermined odor.

[0060] The light stimulation unit 51 includes an LED array or a fiber conduction array with a wavelength or frequency adjustable in a predetermined range, and the fiber conduction array is arranged at intervals of the comb teeth.

[0061] The light source is formed by an LED array with a wavelength range adjustable from 460 to 1100 nm, and the light is transmitted to the cerebral cortex by a fiber conduction array, wherein the frequency of the light stimulation is adjustable from 0.5 to 100 Hz, and the duty cycle is programmable from 10% to 90%, thereby realizing a more flexible and multi-sided light stimulation scheme.

[0062] The sound wave stimulation unit 52 includes one or more of a bone conduction speaker and an air conduction speaker.

[0063] In the embodiment, the sound wave stimulation unit 52 is formed by a combination of a bone conduction speaker and an air conduction speaker to form a composite sound wave stimulation, which is pre-modulated to maintain a harmonic relationship between the fundamental frequency and the target brain wave frequency.

[0064] The vibration stimulation unit 53 comprises a composite vibration system composed of an embedded micro motor, a piezoelectric ceramic vibration sheet or various mechanical vibration mechanisms.

[0065] In this application, the mechanical resonance frequency is set to 0.5-50Hz, and the amplitude of vibration is adjusted according to the pre-set classification.

[0066] The odor stimulation unit 54 comprises a multi-cavity fragrance storage structure and a temperature-controlled volatilization module, which is used to control the fragrance of the multi-cavity fragrance storage structure to release odor according to the predetermined volatilization speed.

[0067] In an optional embodiment, the multi-cavity fragrance storage structure is a closed aromatherapy box 541, and the temperature-controlled volatilization module comprises a heating element and an electrically controlled valve for controlling the opening and closing degree of the aromatherapy box, which can release odor molecules with an accuracy of 0.1ml / min.

[0068] In order to adjust according to the use of the user, this application also introduces a closed-loop feedback regulation mechanism. Specifically, the brain wave signal acquisition module 30 acquires the brain wave signal during use, and the built-in model algorithm intelligently analyzes the brain wave database in the data storage module and the stimulation scheme based on the brain wave signal and the impedance signal during use, and triggers the control module to adjust the stimulation intensity, frequency or mode of the stimulation behavior.

[0069] Preferably, the closed-loop feedback regulation mechanism is based on a neural network model for algorithm iteration, so as to improve the stimulation scheme according to the needs and habits of the user, and improve the intervention and health care effect.

[0070] Specifically, it also includes a comb handle 11, and the comb body 10 is detachably connected to one end of the comb handle 11. The comb body 10 is provided with bristles 101 formed by optical fiber bundles, which are used to collect and transmit near-infrared light for collecting skin impedance signals. In actual use, more realistic and effective skin impedance data can be formed after simultaneous collection of multiple optical fiber bundles and regional weighted processing, thereby enhancing the efficiency and quality of closed-loop feedback regulation.

[0071] The following are two example combination stimulation schemes. Those skilled in the art can adaptively modify the pre-set stimulation scheme of the intelligent comb according to needs, thereby forming more diversified health care and physiotherapy schemes.

[0072] First stimulation scheme: Alzheimer's disease intervention mode

[0073] Activate gamma wave stimulation: set 40Hz light pulse (duty cycle 30%), cooperate with 80Hz harmonic sound frequency, mechanical vibration adopts 40Hz main frequency superimposed with 5Hz modulation wave, and the aromatherapy box releases Huperzine A microcapsule and rosemary essential oil composite preparation.

[0074] Second stimulation scheme: stress release before sleep, sleep aid mode

[0075] Start theta wave dominant scheme: 7Hz light sound synchronization stimulation, vibration module generates 0.5-3Hz imitation cradle wave, aromatherapy box releases lavender and valerian extract mixed volatile agent, adjusts stimulation intensity according to heart rate variability (HRV).

[0076] In order to make the user have a more personalized experience when using the smart comb, it also includes a user interaction module 90 connected with the control module 50, which is used to feedback the parameters of the stimulation scheme and the stimulation behavior. The user interaction module 90 includes a touch screen, a voice control module or a multi-mode interaction system composed of multiple interaction modules. The user can edit input or select the corresponding parameters of the stimulation scheme or adjust the stimulation behavior through the user interaction module, such as through the way of point control touch screen or voice input to realize the selection of the stimulation scheme or the adjustment of the parameters of the stimulation behavior.

[0077] It can be understood that the initial stimulation scheme is determined by default by the control module 60 and the data storage module 40 based on the brain wave signal and the brain wave database. However, when the user has personalized needs and manually sets or adjusts the initial stimulation scheme, the priority of the setting or adjustment is higher than that of the system default initial stimulation scheme.

[0078] More preferably, the user interaction module 90 is connected with the networking communication module 200, and the user can directly customize the control of each stimulation module through the software app or applet on the mobile terminal (such as mobile phone, tablet computer).

[0079] As an optional embodiment, the comb body 10 is detachably connected to one end of the comb handle 11 by plugging, the inside of the comb handle 11 serves as a containing part of the power supply module 70, and the end of the comb handle 11 and the comb body 10 are designed in a power plugging manner. The power supply module 70 can be taken out and charged separately, and the comb body 10 can be used as a normal comb without being connected to electricity, which further enriches the use scenarios and functions of the comb.

[0080] As shown in Figure 2 , the aromatherapy box 541 can be arranged on the comb body 10, but in some embodiments, due to the large number of modules arranged on the comb body 10, the aromatherapy box 541 can also be arranged on the comb handle 11 as shown in Figure 3 .

[0081] In order to make the comb body 10 comfortable when in contact with the human body, a biocompatible material substrate such as silica gel is arranged on the surface of the comb body 10.

[0082] In use, under the condition that the power supply module 70 is turned on, the user contacts the end of the comb teeth 20 with the scalp and stays for about 1-2s,Figure 5 As shown, the brain wave signal acquisition module 30 acquires the brain wave signal and sends it to the control module 60, the control module 60 determines the initial stimulation scheme based on the brain wave signal and the brain wave database, the multi-modal stimulation generation module 50 generates the corresponding stimulation behavior according to the initial stimulation scheme, during the stimulation behavior, the impedance signal acquisition module 80 acquires the skin impedance signal, the control module 60 adjusts the stimulation intensity of the stimulation behavior based on the skin impedance signal, thereby performing intelligent closed-loop feedback head stimulation, or directly using the touch screen of the user interaction module 90 or the voice control module to realize the selection of the initial stimulation scheme or the adjustment of the parameters during the stimulation behavior.

[0083] In summary, the intelligent comb constructs a dynamic closed-loop neuro-physiological collaborative intervention system by modularly integrating the dual-modal biosensing of brain waves and skin impedance signals, combining multi-modal physical stimulation and cloud collaborative algorithms. The technical core lies in the use of brain wave acquisition modules and impedance detection modules distributed in the gaps or tips of the comb teeth to synchronously acquire scalp neural electrical activity and skin impedance changes, forming a multi-dimensional physiological state evaluation system. Through cross-analysis of the brain wave database, stimulation scheme and data by the built-in model algorithm, the intelligent comb intelligently triggers the combination mode of light, sound, odor, vibration and other composite stimuli, achieving intelligent intervention and adjustment for health needs such as cognitive function protection, mood and sleep improvement, prevention of neurodegenerative diseases, and optimization of daily functions. The networking communication module supports remote algorithm iteration and data sharing, enabling the stimulation strategy to be continuously optimized based on cloud training models and user group data, improving the intervention accuracy. Through the closed-loop mechanism of biological signal feedback and dynamic adjustment of stimulation parameters, the system upgrades traditional physical care to an intelligent neuroregulation tool with adaptive ability, and integrates complex monitoring and intervention processes into daily combing actions with the aid of non-invasive design, balancing ease of use and depth of health management, and expanding the cross-border integration potential of wearable devices in the fields of scalp care, stress relief and brain-computer interface applications.

[0084] The above is only a preferred embodiment of the present application, not any form of limitation on the present application, although the present application has been disclosed as above with a preferred embodiment, however, it is not intended to limit the present application, any person skilled in the art, without departing from the scope of the technical solution of the present application, can make some changes or modifications to the above disclosed technical content to make equivalent embodiments with equivalent changes, but as long as it does not deviate from the technical solution content of the present application, any brief modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application, all still belong to the scope of the technical solution of the present application.
