Figures 1-8The hand massager provided in the first embodiment of the present invention at least includes a base 1, an upper cover 2 and a cavity 3 arranged therebetween. The cavity 3 is surrounded by a first lining member 39 and a second lining member 310 and is provided with a plurality of airbags for different areas of the hand, including finger airbags 34, back of hand airbags 35, upper wrist airbags 361, lower wrist airbags 362 and palm airbags 37. The airbags are all connected to the solenoid valve 31 and the air pump 32 through the air tube to provide alternating airbag massage; the cavity 3 extends to the middle of the user's arm, and is provided with two or more EMS electrotherapy pads 38, which are respectively attached to the key parts of the wrist and forearm. The EMS electrotherapy pads 38 are connected to the control board 33 and can independently or in combination control the output of low-frequency electric pulse signals to achieve deep nerve and muscle stimulation and enhance the massage therapy effect. The output control of the EMS electrotherapy pad 38 can be synchronized with the airbag action or triggered at an off-time to form a synergistic stimulation mode. An inclination angle α is set at the bottom of the cavity 3, so that the user's palm and wrist maintain a natural fit posture, improving the fit and comfort. The inclination structure is fixed or suspended. An elastic element such as a spring, silicone pad or other elastic element is provided under the suspended inclination structure to adapt to different user hand shapes; a lithium battery 311 is also provided in the hand massager to power the air pump, solenoid valve, control system and electrotherapy module, making it portable.

[0033] The EMS electrotherapy sheet 38 is respectively attached to the inner wall of the wrist and the middle part of the forearm to provide electrical stimulation to different muscle areas.

[0034] The cavity 3 is an integrated closed structure, in which the electrotherapy module, the airbag system and the control module are integrated to form an overall portable device.

[0035] The solenoid valve 31 is a key component for controlling the inflation and deflation of the airbags. It receives signals from the control board 33 to precisely open and close the air circuit, thereby controlling the inflation and deflation of each airbag. The solenoid valve 31 is connected to the air pump 32 and the airbags via air pipes, forming a closed air circuit system. This precise control of the solenoid valve 31 enables the massager to provide users with a massage experience of varying intensities and rhythms according to pre-set programs.

[0036] The air pump 32 is one of the power sources of the hand massager, responsible for providing sufficient air pressure to each airbag. The air pump 32 is typically connected to the solenoid valve 31 and the control board 33. Receiving instructions from the control board 33, the air pump 32 supplies air to the airbags at an appropriate rate and pressure. The performance of the air pump 32 directly affects the massage effect and user experience.

[0037] The control board 33 is the brains of the hand massager, responsible for processing user commands and controlling the coordinated operation of various components. It connects to components such as the solenoid valve 31, air pump 32, and EMS electrotherapy pads 38 to precisely control the massage program. In practice, the control board 33 may also include fault detection and self-protection circuits to ensure safe operation of the massager.

[0038] Finger airbags 34 are located within cavity 3, corresponding to the user's individual fingers. These airbags are connected to solenoid valves 31 and air pumps 32 via air tubes. By inflating and deflating, they simulate the squeezing and stretching effects of fingers, thereby alleviating finger fatigue and stiffness. The design of the finger airbags 34 must fully consider the physiological structure of the fingers and massage needs to ensure a comfortable and effective massage.

[0039] The back-of-the-hand airbag 35 covers the entire back of the user's hand, providing a comprehensive massage experience through inflation and deflation. Its connection to the solenoid valve 31 and air pump 32 is similar to that of the finger airbag 34, but its size and shape are different to accommodate the area and curvature of the back of the hand. The massage provided by the back-of-the-hand airbag 35 helps promote blood circulation and relieve muscle tension in the hand.

[0040] The wrist airbag 36 is located at the lower end of cavity 3, corresponding to the user's wrist. By inflating and deflating, it simulates the twisting and stretching of the wrist, thereby alleviating wrist fatigue and pain. The design of wrist airbag 36 fully considers the fragility of the wrist and the need for massage to ensure a safe and effective massage.

[0041] The palm airbag 37 is located in the center of the cavity 3, corresponding to the user's palm. It provides a deep massage experience for the palm through the inflation and deflation action. The massage of the palm airbag 37 helps to relax the palm muscles and improve the flexibility and grip strength of the hand.

[0042] The EMS electrotherapy sheet 38 is one of the innovative components of the hand massager. It uses microcurrent to stimulate the muscles and nerves of the hand, achieving deep muscle relaxation and pain relief. The EMS electrotherapy sheet 38 is typically attached to specific acupuncture points on the middle of the arm, wrist, or palm of the hand. It is connected to the control panel 33 to receive precise current signals. Users can adjust the intensity and frequency of the current through the control panel 33 to meet different massage needs. The introduction of the EMS electrotherapy sheet 38 allows the hand massager to add the function of electrotherapy stimulation on top of traditional physical massage, thereby improving the depth and effectiveness of the massage.

[0043] The EMS electrotherapy sheet 38 is a medical device component that uses microcurrent to stimulate muscles and nerves. It transmits weak electrical signals to human tissue, triggering muscle contraction and nerve conduction, thereby achieving deep muscle relaxation, pain relief, and muscle function recovery.

[0044] The EMS electrotherapy sheet 38 operates based on the principles of electrophysiology. When an electric current signal acts on human tissue, it causes changes in cell membrane potential, triggering the conduction of nerve impulses and muscle contraction. By adjusting parameters such as the current intensity, frequency, and waveform, the degree of muscle contraction and the speed of nerve conduction can be precisely controlled.

[0045] In the hand massager, EMS electrotherapy pads 38 are cleverly integrated into the device, aligning with specific acupuncture points on the mid-arm, wrist, or palm. Precisely controlled by the control panel 33, the EMS pads 38 provide the user with electrical stimulation at varying intensities and rhythms, alleviating arm pain and improving hand dexterity and grip strength. Compared to traditional physical massage, EMS electrotherapy stimulation penetrates deeper into muscle tissue, delivering a more sustained and significant massage effect.

[0046] The advantages of EMS electrotherapy tablets 38 are:

[0047] (1) Deep muscle stimulation: EMS electrotherapy stimulation can penetrate deep into muscle tissue, triggering deep muscle contraction and relaxation, thereby achieving a more thorough massage effect.

[0048] (2) Personalized settings: Users can adjust parameters such as the intensity, frequency, and waveform of the current through the control panel 33 according to their personal needs and hand conditions to meet different massage needs.

[0049] (3) Safety and comfort: EMS electrotherapy stimulation usually uses weak current signals and will not cause any harm to the human body. At the same time, through reasonable parameter settings and optimized design of electrode patches, the comfort and safety of massage can be ensured.

[0050] (4) Portable and easy to use: Hand massagers are usually designed to be small and lightweight, allowing users to perform massages anytime and anywhere. The integration of EMS electrotherapy pads 38 allows the device to provide traditional physical massage while adding electrotherapy stimulation, thereby improving the device's practicality and user experience.

[0051] The innovative significance of EMS electrotherapy tablet 38 lies in:

[0052] (1) Breaking through the limitations of traditional massage: Traditional hand massagers mainly rely on physical massage methods, such as airbag squeezing and roller kneading. However, these methods can only act on the surface of the muscle and have difficulty penetrating deep into the muscle tissue. The introduction of EMS electrotherapy tablets 38 breaks through this limitation and achieves the effect of deep muscle stimulation and pain relief.

[0053] (2) Meeting diverse needs: Different users have different hand conditions and massage needs. The EMS electrotherapy sheet 38 can provide precise current stimulation parameters based on the needs and hand conditions of different users through personalized settings, thereby meeting diverse massage needs.

[0054] (3) Promote the development of hand massage technology: The application of EMS electrotherapy tablets 38 in hand massagers marks the innovation and progress of hand massage technology. It not only improves the depth and effect of massage, but also provides new ideas and directions for the development of hand massage technology.

[0055] The upper cover 2 and the base 1 are tightly connected by snaps or screws to form a closed cavity 3 environment.

[0056] The base 1 is provided with a battery compartment or power interface to provide power support for the massager. The battery compartment is provided with a lithium battery 311.

[0057] The microprocessor includes: one of the STM32 series microprocessor, PIC series microprocessor and AVR series microprocessor.

[0058] The STM32 series of microprocessors, launched by STMicroelectronics, features high performance, low power consumption, and ease of programming. Its built-in ARM Cortex-M core can efficiently handle complex control tasks.

[0059] The PIC series of microprocessors, manufactured by Microchip Technology, are widely used in embedded systems. They feature compact packaging, a rich set of peripheral interfaces, and strong control capabilities.

[0060] The AVR series of microprocessors are characterized by high speed, low power consumption, and high performance. Their built-in Flash memory facilitates programming and debugging, making them ideal for use in the control board of a hand massager.

[0061] In this embodiment, the microprocessor selected is the STM32 series microprocessor STM32F407VG.

[0062] The functions of the microprocessor are:

[0063] (1) Command processing: The microprocessor is responsible for receiving and processing commands from the user interface, such as massage mode selection, massage intensity adjustment, etc.

[0064] (2) Data calculation: According to user instructions, the microprocessor performs calculations to determine the working status of each component.

[0065] (3) Control coordination: The microprocessor sends control signals to the solenoid valve 31, air pump 32, EMS electrotherapy sheet 38 and other components to achieve the coordinated operation of the massager.

[0066] (4) Status monitoring: The microprocessor is also responsible for monitoring the working status of the massager, such as airbag pressure, electrotherapy intensity, etc., to ensure the safety and effectiveness of the massage process.

[0067] The power management module includes a power adapter, a power filter capacitor, a voltage regulator, and an overload protector. The positive terminal of the power filter capacitor is connected to the positive terminal of the power adapter, the negative terminal of the power filter capacitor is connected to the negative terminal of the power adapter, the positive terminal of the power filter capacitor is connected to the input terminal of the voltage regulator, and the negative terminal of the power filter capacitor is connected to the common terminal of the voltage regulator. The output terminal of the voltage regulator is respectively connected to the power terminals of the microprocessor, solenoid valve 31, air pump 32, and EMS electrotherapy sheet 38, forming a complete power supply circuit. The overload protector is connected in series with the power management module. The stable voltage output by the voltage regulator powers the microprocessor, solenoid valve 31, air pump 32, EMS electrotherapy sheet 38, and other components.

[0068] The power adapter converts AC power into DC power, providing a stable power supply voltage for the massager. The DC power output by the power adapter first passes through a filter capacitor to smooth out voltage fluctuations.

[0069] The power filter capacitor is used to smooth the DC power output by the power adapter and reduce the impact of voltage fluctuations on the massager.

[0070] The filtered DC power goes to the voltage regulator, which stabilizes it to the required voltage range. The voltage regulator keeps the power supply voltage within the voltage range required by the microprocessor and other components.

[0071] The overload protector is used when the massager is overloaded. The thermal or magnetic sensitive element inside the overload protector will be activated and the power supply will be automatically cut off to protect the massager from damage.

[0072] The input / output interface (I / O) bridges the gap between the hand massager and the user, receiving user commands and outputting status information. The I / O interface includes a pushbutton switch, display, indicator light, and an interface connector. One end of the pushbutton switch is connected to ground, while the other end is connected to an input pin of the microprocessor. When the user presses a key, the microprocessor detects a low-level signal, thereby recognizing the user's input. The display's data and control lines are connected to the microprocessor's data and control buses, respectively. The microprocessor displays information by sending data and control signals to the display. One end of the indicator light is connected to ground, while the other end is connected to an output pin of the microprocessor. The microprocessor controls the state of the output pin to turn the indicator light on and off. The power adapter connects to the power management module via the interface connector to provide power to the massager. External devices, such as USB ports, connect to the microprocessor via the interface connector to enable data transmission and device control.

[0073] The key switch is used to receive user input, such as massage mode selection, massage intensity adjustment, etc.

[0074] The display screen is used to display information such as the massager's working status, massage mode, and massage intensity.

[0075] The indicator light is used to indicate the power status, working status, etc. of the massager.

[0076] Interface connectors are used to connect external devices, such as power adapters, USB ports, etc.

[0077] The communication module is responsible for communication between the hand massager and external devices or systems, such as connection to smartphone apps and remote monitoring. The communication module includes a wireless communication chip, an antenna, and a communication interface circuit. The wireless communication chip connects to the antenna via RF pins to transmit and receive wireless signals. The data and control lines of the wireless communication chip connect to the microprocessor's data bus and control bus, respectively. The microprocessor communicates with external devices or systems by sending data and control signals to the wireless communication chip. The communication interface circuit connects to external electronic devices, such as smartphone apps and remote monitoring centers, via an interface connector, enabling data transmission and control signal reception.

[0078] Wireless communication chips include Bluetooth, Wi-Fi, or Zigbee chips. Bluetooth is a widely used wireless communication technology with advantages such as low power consumption, low cost, and easy connectivity. Bluetooth chips can connect hand massagers to devices such as smartphones and tablets, enabling data transmission and remote control.

[0079] Wi-Fi technology has the advantages of fast transmission speed and long transmission distance. The Wi-Fi chip can connect the hand massager to the home network or the Internet, thus supporting advanced functions such as remote monitoring and software upgrades.

[0080] Zigbee technology is a low-power, short-range wireless communication technology. Zigbee chips are suitable for building wireless sensor networks within a small area, enabling the interconnection of hand massagers and other health monitoring devices.

[0081] It's important to note that when choosing a wireless communication chip, you need to consider factors such as the hand massager's usage scenario, functional requirements, and cost budget. For example, for products requiring remote control, Bluetooth or Wi-Fi chips are recommended; for products that require building a wireless sensor network, Zigbee chips are recommended.

[0082] The antenna is the interface between the wireless communication chip and the outside world for exchanging electromagnetic waves. Its design directly impacts the performance and stability of wireless communication. In hand massagers, antennas typically take the form of printed circuit board (PCB) antennas or ceramic antennas. These antennas offer advantages such as small size, light weight, and ease of integration, meeting the wireless communication performance requirements of hand massagers.

[0083] The communication interface circuit is a bridge for data transmission between the wireless communication chip and external electronic devices. The communication interface circuit includes: a data bus and a control bus.

[0084] The data bus is responsible for transmitting data between the wireless communication chip and external electronic devices. It consists of multiple data lines, each corresponding to a data channel. During communication, data signals on the data bus are transmitted bidirectionally between the wireless communication chip and the external electronic device.

[0085] The control bus is responsible for transmitting control signals between the wireless communication chip and external electronic devices. It includes clock lines, reset lines, and interrupt lines. These control signals are used to coordinate the operating status and data transmission timing between the wireless communication chip and external electronic devices.

[0086] In the communication interface circuit, the wireless communication chip's data and control lines connect to the microprocessor's data and control buses, respectively. This allows the microprocessor to send control commands to the wireless communication chip via the control bus and read or write data via the data bus. The wireless communication chip also receives and transmits wireless signals via its antenna, enabling communication with external electronic devices.

[0087] The base 1 is made of high-strength, wear-resistant cast iron or steel. Cast iron bases are widely used in industry due to their high strength, wear resistance, and corrosion resistance, and are particularly suitable for applications requiring stable support. They ensure a perfect fit with the equipment and reduce equipment failures caused by deformation of the base 1. High-strength steel is not only relatively low-cost but also easy to process and produce. It meets the rigidity and strength requirements of product designs and has excellent energy absorption properties, allowing it to withstand greater loads.

[0088] The upper cover 2 is made of aluminum alloy, glass fiber reinforced plastic, polypropylene or polyvinyl chloride.

[0089] Aluminum alloy has the advantages of light weight, high strength, and good corrosion resistance. As the upper cover 2, it can effectively reduce the overall weight while ensuring sufficient strength and durability.

[0090] The upper cover 2 is made of light and durable materials so that the user can open and close it easily while ensuring the safety of the internal components. In specific implementation, the upper cover 2 can also be provided with an operation panel or display screen to facilitate the user to select and set functions.

[0091] Glass fiber reinforced plastic (GFRP) is characterized by its high strength, light weight, and corrosion resistance. In the application of the upper cover 2, GFRP can provide excellent structural strength and weather resistance while maintaining a low weight.

[0092] Polypropylene (PP) is lightweight, corrosion-resistant, and easy to process, making it suitable for applications where weight and corrosion resistance are important. Polyvinyl chloride (PVC) is also lightweight, corrosion-resistant, and relatively inexpensive.

[0093] In specific implementation, a first lining member 39 is provided above one side of the cavity 3, a second lining member 310 is provided below one side of the cavity 3, and a third lining member 312 is provided above the other side of the cavity 3. The third lining member 312 can be made hidden.

[0094] The first lining member 39, located above one side of the cavity, primarily enhances structural stability and supports key components such as the solenoid valve and air pump, ensuring stable operation during massage and reducing vibration and noise, providing a tranquil massage environment. It also provides a certain cushioning function, protecting delicate internal components from external impact.

[0095] The second lining 310, located below one side of the cavity, effectively isolates the hand airbag from direct contact with the base, preventing wear and noise caused by friction and extending the life of the device. It also helps regulate the inflation efficiency of the airbag, ensuring even distribution of massage force and enhancing the massage effect.

[0096] The third lining member 312 is located above the other side of the cavity. Its concealed design not only enhances aesthetics but also streamlines the product's overall appearance without sacrificing structural strength, enhancing user comfort. This concealed design also facilitates cleaning and maintenance, reducing the space where dirt and grime can accumulate, and maintaining a clean and hygienic environment.

[0097] In a specific implementation, the wrist airbag 36 can also be provided in two parts, namely an upper wrist airbag 361 and a lower wrist airbag 362 .

[0098] The dual airbag design provides a more comprehensive wrist wrap, delivering a more three-dimensional and detailed massage experience. The upper wrist airbag 361 focuses on the back of the wrist, helping to alleviate symptoms such as carpal tunnel syndrome caused by prolonged keyboard or mouse use. The lower wrist airbag 362, on the palm side of the wrist, effectively relieves muscle tension and pain caused by heavy lifting or frequent wrist movements.

[0099] The independent control of the two airbags allows the massager to be personalized based on the user's wrist size and massage needs, ensuring optimal results every time. Through precise microprocessor control, the upper wrist airbag 361 and the lower wrist airbag 362 work together to simulate a massage technique more closely resembling that of a real masseur, enhancing the user's overall comfort.

[0100] This design also enhances the massager's adaptability and flexibility, enabling it to meet a wider range of massage scenarios and needs. Whether it's targeted treatment for specific wrist issues or daily hand relaxation and maintenance, the dual wrist airbags provide just the right massage support, allowing users to enjoy a massage while also experiencing the convenience and comfort brought by technology.

[0101] The design of the hand massager of the present invention fully considers the principles of ergonomics to ensure that users can obtain the best comfort and massage effect during use. Specifically:

[0102] (1) Palm and wrist angle design: The palm and wrist are designed to an angle α that conforms to the natural curve of the human body to ensure that the user can feel a natural fit and support when placing the hand. This design helps reduce hand fatigue during massage and improves the comfort and effectiveness of the massage.

[0103] (2) Airbag shape and size design: The shape and size design of each airbag must fully consider the physiological structure of the hand and the massage needs. Through reasonable airbag layout and inflation volume control, comprehensive coverage and precise massage of all parts of the hand can be achieved. At the same time, the material of the airbag must have good elasticity and breathability to ensure the comfort and safety of the massage.

[0104] (3) Design of the attachment position of the EMS electrotherapy sheet: The attachment position of the EMS electrotherapy sheet needs to be reasonably designed according to the distribution characteristics of the arm muscles and nerves. By selecting the appropriate acupoints and attachment methods, it can be ensured that the current signal can accurately act on the target muscles and nerve tissues, thereby achieving the best massage effect.

[0105] The present invention has the following beneficial effects through the design of the above embodiments:

[0106] The first to integrate EMS electrotherapy tablets into a hand massager, forming a mechanical and electric pulse combined stimulation method, breaking through the limitations of traditional physical massage;

[0107] Extend the cavity to cover the forearm to achieve a wider range of massage and treatment effects;

[0108] The ergonomic angled structure design improves comfort and fit;
