Description

Technical Field

[0001] This invention relates to the field of gua sha equipment technology, specifically to an intelligent electronic gua sha board and its usage method. Background Technology

[0003] Most existing electronic gua sha boards can only sense the contact force between the board surface and the skin, failing to acquire the grip strength and the spatial angle of contact between the board surface and the skin. This leads to misjudgments during gua sha, such as "gripping too lightly but pressing too hard" or "the angle being too steep," making it difficult to ensure the safety of gua sha. Some products rely on user experience to adjust the angle and force, lacking electronic data guidance, which can easily cause beginners to over-exert or perform ineffective gua sha. In terms of structural design, existing products mostly use a single-point thin-film pressure plate solution, which has a short lifespan due to bending resistance, is susceptible to corrosion from sweat, and has defects such as large precision drift, affecting the user experience. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent electronic gua sha board and its usage method. It solves the problems of existing electronic gua sha boards, which mostly only perceive the contact force between the board surface and the skin, failing to acquire hand grip strength and the spatial angle of contact between the board surface and the skin. This leads to misjudgments during gua sha, such as "gripping too lightly but pressing too hard" or "the angle being too steep," making it difficult to ensure the safety of gua sha. Some products rely on user experience to adjust the angle and force, lacking electronic data guidance, which can easily lead to over-scraping or ineffective gua sha for beginners. In terms of structural design, existing products mostly use a single-point thin-film pressure plate solution, which has short lifespan due to bending resistance, is susceptible to corrosion from sweat, and suffers from large precision drift, affecting the user experience.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] As a preferred embodiment of the present invention, it includes a handle and a gua sha board body. The outer surface of the handle is equipped with a ring-shaped arrangement of pressure sensors. The output ends of multiple pressure sensors are connected to an anti-slip pad. A connecting frame is connected to the right side of the handle. A display screen is mounted on the upper surface of the connecting frame. Indicator lights arranged at equal intervals are mounted on the upper surface of the display screen. A ring-shaped arrangement of support frames is connected to the bottom surface of the connecting frame. One end of two sets of support frames is connected to a connecting plate. A pressure sensing module is mounted on the bottom surface of the connecting plate. A fixing plate is installed at the output end of the pressure sensing module. Two spatial angle sensing modules are installed on the bottom surface of the fixing plate. A comfort pad is connected to the outer surface of the gua sha board body. A groove is opened on the upper surface of the gua sha board body. The output ends of the two spatial angle sensing modules are connected to the gua sha board body. A cavity is opened on the left side of the handle. A protective pad is connected to the inner bottom wall of the cavity. A battery is installed on the upper surface of the protective pad. An intelligent control module is installed on the upper surface of the battery. An inspection door is hinged to the inner wall of the handle.

[0007] As a preferred embodiment of the present invention, the intelligent control module is electrically connected to each pressure sensor, the pressure sensing module and the two spatial angle sensing modules respectively, and the three sets of pressure sensors are a ring-shaped three-dimensional force-sensitive silicone array.

[0008] As a preferred embodiment of the present invention, the pressure sensing module comprises an ultra-thin flexible PCB, and the connecting frame is a PEEK elastic beam structure.

[0009] As a preferred technical solution of the present invention, the intelligent control module adopts a Nordic nRF series main MCU, and the intelligent control module has a built-in contact force-angle joint threshold matrix and angle-force fusion algorithm.

[0010] As a preferred embodiment of the present invention, the intelligent control module has a built-in wireless communication module that supports wireless communication with a mobile phone App, and the comfort pad is made of medical-grade conductive silicone.

[0011] A method for monitoring the force and angle of an electronic gua sha tool, comprising the following steps: S1: After the device is started, the pressure sensor, pressure sensing module and spatial angle sensing module start up simultaneously, and collect the gripping force Fg, contact force Fs and IMU raw signals at a sampling frequency of 1kHz. S2: The intelligent control module completes the hardware decoupling of Fg and Fs through the mechanical differential structure of "hand force - contact force" and the full-bridge strain gauge signal. Combined with the signal converted by 24-bit ADC, it outputs the accurate measurement values ​​of Fg and Fs. S3: The spatial angle sensing module uses a MEMS six-axis IMU and a temperature compensation chip, combined with a Kalman filter fusion algorithm, to calculate the pitch angle θp and roll angle θr, and output the spatial angle θ. S4: The intelligent control module calls the built-in "contact force-angle" joint threshold matrix and compares the real-time collected Fs and θ with the threshold matrix; S5: If Fs does not exceed the user-defined upper limit and θ is within the safe slope range, the RGB color wheel in the feedback prompt unit continuously maps the size of Fs, maintaining normal working status; S6: If Fs exceeds the user-set upper limit or θ exceeds the safe slope range, a first-level or second-level alarm will be triggered according to the excess amplitude. The indicator light (8) will display different colors, vibrations and prompts according to the corresponding level, and the action curve will be recorded at the same time. S7: Users can view real-time Fs-θ curves, motion recording data, and AI scoring through a mobile app, and can also upgrade the threshold matrix online via OTA to adapt to different usage scenarios.

[0012] Compared with the prior art, the present invention provides an intelligent electronic gua sha board and its method of use, which has the following beneficial effects: 1. Multi-dimensional perception and precise measurement: Through the collaborative design of the handheld pressure sensing module and the gua sha contact pressure sensing module, the true values ​​of "handheld grip force Fg" and "plate surface-skin contact force Fs" are obtained simultaneously through dual channels, with a measurement error of ≤±0.1N; combined with MEMS six-axis IMU and temperature compensation chip, the spatial angle θ (pitch + roll) is calculated in real time with an accuracy of ≤±2°, which solves the problem of single sensing dimension of existing products.

[0013] 2. Intelligent safety protection and early warning: Based on the "contact force-angle" joint threshold matrix, when Fs exceeds the set upper limit or θ exceeds the safe slope range, a three-level combined alarm is realized through RGB color ring, vibration and prompt sound, which effectively prevents subcutaneous bleeding and ensures the safety of scraping, especially suitable for beginners.

[0014] 3. Structural optimization and performance improvement: Adopting a flexible three-dimensional force-sensitive array + MEMS six-axis fusion solution, combined with PEEK elastic beam and mechanical differential structure, the bending life exceeds 500,000 cycles and is not easily corroded by sweat, with high precision and stability; Optimized low power consumption design, the power consumption of the whole machine is ≤3mA after Bluetooth broadcast is turned off, and the continuous working time is ≥2h, which solves the problems of structural defects and insufficient battery life of existing products.

[0015] 4. Personalized Adaptation and Convenient Interaction: Supports OTA online upgrade of threshold matrix, which can be adapted to different groups of people such as the elderly, children, and athletes, as well as different scraping parts; Real-time data display, action recording and AI scoring are realized through mobile app, providing electronic data guidance to avoid excessive or ineffective scraping and improve the user experience.

A pressure sensing module 12 is mounted on the bottom surface of the connecting plate 11. A fixing plate is mounted on the output end of the pressure sensing module 12. 13. Two spatial angle sensing modules 14 are installed on the bottom surface of the fixed plate 13. A comfort pad 17 is connected to the outer surface of the scraping board body 15. A groove 16 is opened on the upper surface of the scraping board body 15. The output ends of the two spatial angle sensing modules 14 are connected to the scraping board body 15. A cavity 2 is opened on the left side of the handle 1. A protective pad 3 is connected to the inner bottom wall of the cavity 2. A battery 4 is installed on the upper surface of the protective pad 3. An intelligent control module 5 is installed on the upper surface of the battery 4. An inspection door 18 is hinged to the inner wall of the handle 1, which can make the equipment more intelligent and facilitate people's use of the equipment.

[0020] In this embodiment, the intelligent control module 5 is electrically connected to each pressure sensor 19, the pressure sensing module 12, and two spatial angle sensing modules 14. The three pressure sensors 19 form a ring-shaped three-dimensional force-sensitive silicone array. The pressure sensing module 12 includes an ultra-thin flexible PCB and a PEEK elastic beam structure for the connecting frame 6. When the measured values ​​of Fs and θ fall within 10% of the matrix outer frame, a first-level alarm is triggered, consisting of a yellow ring, a light vibration, and a short tone. When the values ​​fall within 5% of the matrix outer frame, a second-level alarm is triggered, consisting of a flashing red ring, a heavy vibration, a long tone, and forced vibration stop.

The intelligent control module 5 has a built-in contact force-angle joint threshold matrix and angle-force fusion algorithm. The intelligent control module 5 has a built-in wireless communication module, which supports wireless communication with mobile phone App. The comfort pad 17 is made of medical grade conductive silicone, which not only makes it convenient for people to use the device, but also makes people more comfortable when using the device for scraping.

[0022] The working principle and usage process of this invention are as follows: During use, the user holds the handle 1, and the annular three-dimensional force-sensitive silicone array 19 collects the gripping force Fg. When the scraping board body 15 contacts the skin, the dual-mode pressure field collects the contact force Fs. The MEMS six-axis IMU 12 and the temperature compensation chip 13 calculate the spatial angle θ in real time. After each signal is synchronously sampled at 1kHz, it is input to the intelligent control module 5, which judges whether it exceeds the safe range through the joint threshold matrix. If it does not exceed the range, the RGB color ring 7 maps the size of Fs, and it works normally. If it exceeds the range, it triggers a first / secondary alarm according to the amplitude. The user can view the data, record actions, and upgrade the threshold matrix through a mobile app to adapt to personal needs. After use, the device can be maintained through the maintenance door 18.
