Technical Field
[0001] This invention relates to the field of intelligent health equipment technology, specifically to a control method for a foot massage device and the foot massage device itself. Background Technology
[0002] The human foot has numerous acupoints and has always been valued in traditional Chinese medicine massage and acupuncture. Especially with the further development of modern Western anatomy and the introduction of the concept of foot reflexology, the ability of foot massage to maintain health and assist in the treatment of certain diseases has gained global consensus. Both the acupoint system of traditional Chinese medicine and the foot reflexology system of the West are practical methods for maintaining and promoting human health, centered on the human foot.
[0003] Most foot massage devices on the market currently use fixed programs and preset modes for massage operations, such as rolling, kneading, or heating. They lack the ability to perceive the physiological characteristics of the user's feet, such as foot shape, foot pressure distribution, and body surface temperature. Moreover, single-mode massage operations are prone to poor massage effects and low comfort, and may even cause risks such as excessive pressure or burns. Summary of the Invention
[0004] In view of this, the present invention provides a control method for a foot massage device and a foot massage device to solve the technical problems of existing foot massage devices being unable to recognize the user's foot structure and having low massage effect and comfort.
[0005] In a first aspect, the present invention provides a control method for a foot massage device, the foot massage device comprising a device body having a pair of foot cavities, each foot cavity having a forefoot region, a midfoot region and a hindfoot region, and each of the forefoot region, the midfoot region and the hindfoot region being provided with a massage module, a heating module and a sensor module; The control method includes: Based on the sensor module, pressure and temperature distribution data of the user's soles in various areas are collected; The pressure distribution data and temperature distribution data of the user's soles in various areas are input into the target recognition algorithm model to determine the user's foot type and foot condition; The foot massage device is controlled to operate based on the user's foot type and foot condition.
[0006] Beneficial effects: By collecting pressure and temperature distribution data of the user's feet in various areas through the sensor module, and combining this data, the user's foot shape and condition can be accurately identified, making the identification more precise. Based on the user's foot shape and condition, massage and heat therapy programs that better match the foot's structural characteristics can be provided, improving the adaptability of the foot massage device. During the massage, changes in foot pressure and temperature can be dynamically sensed through the pressure and temperature distribution data, allowing for real-time adjustments to the foot massage device to prevent overheating or overpressure, thereby improving the comfort and safety of the foot massage device.
[0007] In an optional implementation, the step of inputting the pressure distribution data and temperature distribution data of the user's soles in various regions into a target recognition algorithm model to determine the user's foot type and foot condition includes: The pressure distribution data is input into the target recognition algorithm model to analyze the contact area ratio, pressure peak position and pressure gradient of the foot pressure distribution, and the user's foot type is determined by combining the foot length and the force pattern of the arch area. The temperature distribution data is input into the target recognition algorithm model to determine the blood circulation status and muscle fatigue of the user's feet, thereby determining the condition of the user's feet.
[0008] In an optional implementation, after collecting the user's foot pressure distribution data and temperature distribution data in various areas, and before determining the user's foot type and foot condition, the method further includes: The offset of the user's foot position is calculated based on the pressure distribution data and the temperature distribution data; A reminder command is generated in response to the offset exceeding a set threshold; Based on the reminder instruction, the user is reminded to adjust the position of their feet; After reminding the user to adjust their foot position to meet the preset time, if the user's foot position is not adjusted to the preset position, the foot massage device will stop working.
[0009] In an optional implementation, calculating the offset of the user's foot position based on the pressure distribution data and the temperature distribution data includes: Based on the temperature distribution data, identify the user's foot contact area; In response to missing temperature data in the foot contact area, the user's foot position is determined to be offset; Based on the pressure distribution data in the forefoot and hindfoot regions, the positions of the user's toes and heels are identified to determine the current position of the foot; Based on the current position of the foot and the preset foot position, the deviation between the current position of the foot and the preset foot position is calculated to obtain the offset of the foot position.
[0010] In one optional embodiment, the foot type includes flat feet, high arches, and normal feet; the operating modes of the massage module include kneading, rolling, and patting; the adjustable levels of the massage module include a first level, a second level, and a third level, wherein the pressure value of the first level is less than the pressure value of the second level, and the pressure value of the second level is less than the pressure value of the third level; the operating modes of the heating module include constant temperature mode, incremental mode, intermittent mode, and alternating mode. The step of controlling the foot massage device based on the user's foot type and foot condition includes: In response to the user's flat feet, the massage module in the midfoot area is controlled to roll at the first level, and the heating module in the midfoot area is controlled to operate in a constant temperature mode; the constant temperature mode means that the temperature of the heating module is maintained within a preset temperature range during the operation of the heating module. The massage modules of the forefoot area and the hindfoot area are controlled to perform tapping and / or kneading at the second level. During the operation of the foot massage device, if the pressure in the midfoot area exceeds a preset pressure threshold, the rolling pressure of the massage module is reduced.
[0011] In an optional implementation, controlling the foot massage device based on the user's foot type and foot condition further includes: In response to the user's high arch foot shape, the massage modules of the forefoot and hindfoot areas are controlled to roll and / or knead at the third level, and the heating module is controlled to operate in a progressive mode; the progressive mode is that the temperature of the heating module gradually increases during the operation of the heating module. The massage module in the midfoot area is controlled to roll at the first setting. During the operation of the foot massage device, if the temperature fluctuation of the sole corresponding to the forefoot area, the midfoot area, or the hindfoot area is greater than or equal to the target temperature, the heating module of the current area is controlled to switch to intermittent mode; the intermittent mode is when the heating module switches between working state and stop state during the operation of the heating module. If the fluctuation of the foot temperature is less than the target temperature, the heating module is controlled to continue working.
[0012] In an optional implementation, controlling the foot massage device based on the user's foot type and foot condition further includes: In response to the user's foot type being normal, the massage modules of the forefoot area, the midfoot area, and the hindfoot area are controlled to knead, roll, or pat at any level, and the heating module is controlled to work in an alternating mode; the alternating mode is that during the operation of the foot massage device, the heating modules of the hindfoot area, the midfoot area, and the forefoot area work alternately in sequence; During the operation of the foot massage device, the user's foot position is detected. In response to the user's foot position not being in the preset foot position, the massage module and the heating module are controlled to stop working, and the current position of the foot is calibrated.
[0013] In an optional implementation, after controlling the foot massage device based on the user's foot type and foot condition, the method further includes: During the operation of the foot massage device, pressure distribution data and temperature distribution data of the user's soles in various areas are continuously collected; Based on the pressure distribution data and the temperature distribution data, the user's foot condition is updated in real time; Based on the updated foot condition, adjust the operating modes of the massage module and the heating module.

Each of the forefoot region, the midfoot region, and the hindfoot region is provided with a massage module, a heating module, and a sensor module. The physical guidance components, including heel limiters, foot guide grooves, and positioning patterns, are used to guide the user's foot into a preset foot position.
[0015] Beneficial effects: By incorporating massage, heating, and sensor modules into the forefoot, midfoot, and hindfoot regions of each foot cavity, the sensor modules can detect pressure and temperature distribution data within each area. The massage and heating modules can then operate based on this data to adapt to different application scenarios. Furthermore, the device body features a heel limiting block, a sole guide groove, and positioning patterns. The heel limiting block secures the heel, preventing slippage during massage and ensuring the foot is in the correct massage position. The sole guide groove guides the foot along a specific trajectory into the foot cavity, allowing each part of the foot to accurately align with the corresponding massage, heating, and sensor modules, improving massage precision and effectiveness. The positioning patterns increase friction between the sole and the foot massage device, further helping the user place the foot in the preset position.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] In the description of this invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0022] According to embodiments of the present invention, such as Figures 9 to 11As shown, a foot massage device is provided, including: a device body having a pair of foot cavities, each foot cavity having a forefoot region 100, a midfoot region 200 and a hindfoot region 300, and each of the forefoot region 100, midfoot region 200 and hindfoot region 300 being provided with a massage module, a heating module and a sensor module; and a physical guidance component including a heel limiting block, a sole guide groove and positioning patterns, for guiding the user's foot into a preset foot position.
[0023] In this embodiment, the main body of the device has a symmetrical structure, with a pair of independent foot chambers, namely a left foot chamber and a right foot chamber, for placing the user's left and right feet. Each foot chamber has a forefoot region 100, a midfoot region 200, and a rearfoot region 300. When the user places their foot in the foot chamber, the forefoot and toes are located in the forefoot region 100, and the heel is located in the rearfoot region 300. Massage modules, heating modules, and sensor modules are provided in the forefoot region 100, midfoot region 200, and rearfoot region 300. The sensor modules can detect pressure and temperature distribution data in each region. The massage and heating modules can operate based on the actual pressure and temperature distribution data in each region. For example, the massage and heating modules can be controlled simultaneously in the midfoot region 200, only the massage module in the forefoot region 100, and only the heating module in the rearfoot region 300; or the massage and heating modules in the forefoot region 100, midfoot region 200, and rearfoot region 300 can be controlled simultaneously.
[0024] The device also features a heel stop, a foot guide groove, and positioning patterns. The heel stop accurately positions the heel, preventing it from slipping during massage and ensuring the foot is in the correct massage position, while also providing support. The foot guide groove guides the foot along a specific trajectory into the foot cavity, allowing different parts of the foot to accurately align with the corresponding massage, heating, and sensor modules, improving the accuracy and effectiveness of the massage. The positioning patterns increase friction between the sole of the foot and the foot massage device, further helping the user place the foot in the preset position.
[0025] Furthermore, the foot massage device also has a foot cover liner, which is placed on the foot and then the foot is placed inside the foot cavity. The foot cover liner can be made of memory foam or antibacterial elastic fabric to improve wearing comfort.
[0026] In one embodiment, the sensor module includes a pressure sensor and an infrared temperature sensor. The pressure sensor is used to collect pressure distribution data of the sole of the foot, and the infrared temperature sensor is used to collect temperature distribution data of the sole of the foot. The massage module includes a massage head, which has a drive motor inside. The drive motor is connected to the massage head for controlling the lifting and / or rotation of the massage head. The heating module includes a graphene heating film or a positive temperature coefficient thermistor ceramic sheet.
[0027] In this embodiment, the pressure sensor can be a multi-point pressure sensing unit, such as a capacitive flexible pressure sensing membrane or a resistive flexible pressure sensing membrane. The pressure sensors are distributed across the pressure-bearing areas of the sole, such as the forefoot area 100, the midfoot area 200, and the hindfoot area 300, forming a pressure matrix within these areas. This allows for real-time acquisition of pressure distribution data for each area of the sole. An infrared temperature sensor can be positioned on the periphery of the massage head or on the inner wall of the foot cavity to detect the skin temperature of the sole in a non-contact manner, thereby enabling real-time monitoring of the temperature distribution data of the sole.
[0028] The massage head consists of a metal frame and a flexible silicone surface layer fitted onto the metal frame, ensuring comfort and structural stability. Inside the massage head is a drive motor, which is connected to the massage head to control its lifting and / or rotation. Furthermore, a drive screw or eccentric wheel is also located inside the massage head. The output shaft of the drive motor is connected to one end of the drive screw or eccentric wheel; the other end of the drive screw or eccentric wheel is then connected to the massage head to achieve lifting and / or rotation. Lifting the massage head is achieved by controlling its up-and-down movement perpendicular to the sole of the foot, simulating a tapping motion to massage the user's feet. Rotating the massage head clockwise or counterclockwise around its own axis simulates rolling and kneading motions to massage the user's feet, thus meeting the stimulation needs of different foot muscle types.
[0029] The heating module can be composed of a graphene heating film or a positive temperature coefficient (PTC) thermistor ceramic sheet to ensure heating efficiency while mitigating safety risks through material properties, adapting to the needs of different users. For example, the graphene heating film utilizes the thermal conductivity of graphene; when electricity is applied, carbon atoms vibrate rapidly to generate heat, which is radiated to the sole of the foot in the form of far-infrared rays, achieving a warming sensation from the inside out. Warmth can be felt within 1-2 seconds of being powered on, eliminating the need for a long wait. The film structure can closely conform to the arch curve of the midfoot, ensuring uniform heating of areas such as the arch and midfoot. The positive temperature coefficient (PTC) thermistor ceramic sheet utilizes the characteristic that the resistance of PTC material increases with temperature. When the temperature reaches a set value, the resistance increases sharply, the current approaches zero, and heating automatically stops; when the temperature drops, the resistance recovers, and heating resumes, thus preventing safety hazards caused by overheating of the heating module. The temperature adjustment range of the heating module can be between 25℃ and 45℃, such as 25℃, 27℃, 29℃, 31℃, 33℃, 35℃, 37℃, 39℃, 41℃, 43℃, 45℃, etc., which can be set according to actual usage requirements.
[0030] Furthermore, the foot massage device also includes a control unit, which can switch the working mode of the massage module to enable the massage head to achieve different movement trajectories. The control unit can dynamically control the trajectory, amplitude, frequency and intensity of the massage head by adjusting the motor operating range, pulse frequency and output power, so as to realize the switching of different working modes of the massage module.
[0031] According to embodiments of the present invention, such as Figure 1 As shown, a control method for a foot massage device is provided, including the following steps: Step S100: Collect pressure distribution data and temperature distribution data of the user's feet in various areas based on the sensor module.
[0032] In step S100, the sensor module includes a pressure sensor and an infrared temperature sensor. The pressure sensor can be a multi-point pressure sensing unit, such as a capacitive flexible pressure sensing membrane or a resistive flexible pressure sensing membrane. The pressure sensors are distributed in the pressure-bearing areas of the sole, such as the forefoot area 100, the midfoot area 200, and the hindfoot area 300, forming a pressure matrix in the pressure-bearing areas of the sole, thereby enabling real-time acquisition of pressure distribution data in various areas of the sole. The infrared temperature sensor can be set on the periphery of the massage head or on the inner wall of the foot cavity to detect the skin temperature of the sole in a non-contact manner, thereby enabling real-time monitoring of the temperature distribution data of the sole.
[0033] Step S200: Input the pressure distribution data and temperature distribution data of the user's feet in each area into the target recognition algorithm model to determine the user's foot type and foot condition.
[0034] In step S200, as Figure 2 As shown, the specific steps include: Step S210: Input the pressure distribution data into the target recognition algorithm model, analyze the contact area ratio, pressure peak position and pressure gradient of the foot pressure distribution, and determine the user's foot type by combining the foot length and the force pattern of the arch area. Step S220: Input the temperature distribution data into the target recognition algorithm model to determine the blood circulation status and muscle fatigue of the user's feet, and determine the condition of the user's feet.
[0035] In this embodiment, the target recognition algorithm model can be a multimodal data fusion and pattern recognition algorithm, which fuses the two-dimensional pressure distribution data collected by the pressure sensor with the foot temperature distribution data collected by the infrared temperature sensor. Mechanical features are extracted from the pressure distribution data to determine the various pressure points on the sole of the foot, identify the center of force, and determine the force ratio. Based on the distribution of pressure points, the arch curve is fitted, and the contact area of the sole is further determined, providing a basis for subsequent judgment of the user's foot type.
[0036] In flat feet, the arch area also contacts the ground, resulting in a relatively large contact area for plantar pressure distribution, and there is no obvious arch depression. The peak pressure in flat feet is more concentrated on the medial side of the arch. The rate of change in pressure from high to low pressure areas is relatively gradual, without a significant gradient. In high arches, the peak pressure is mainly concentrated in the forefoot and heel, while the midfoot region (200°) has a smaller contact area with the ground, resulting in a relatively smaller proportion of the plantar pressure distribution in terms of contact area. In normal foot types, the peak pressure is typically distributed in the heel, first metatarsal head, and fifth metatarsal head. At the medial edge of the arch, pressure rapidly transitions from high pressure at the heel or forefoot to low pressure in the arch, exhibiting a significant pressure change. Therefore, by analyzing the contact area ratio, peak pressure location, and pressure gradient of the plantar pressure distribution, and combining this with foot length and the force pattern in the arch area, if the contact area ratio of the midfoot region (200°) is greater than or equal to 45%, and there is no obvious arch depression, the user's foot type is determined to be flat feet. If the contact area of the midfoot region (200 mm) is less than or equal to 20%, and the pressure is mainly concentrated on the heel and forefoot, then the user's foot type is determined to be high arch. If the three-point support structure of the foot is obvious, and the pressure is evenly distributed in the forefoot, arch, and heel areas, then the user's foot type is determined to be normal.
[0037] Thermal features were extracted from the temperature distribution data. Based on the collected plantar temperatures of the forefoot region (100), midfoot region (200), and hindfoot region (300), the temperature differences between each region were compared. When the foot is in a healthy state, the plantar temperature distribution is relatively uniform and within the normal temperature range for the human foot. After inputting the temperature distribution data into the target recognition algorithm model, the model analyzes the blood circulation and muscle fatigue of the user's foot. If a certain area of the foot experiences high pressure but low temperature, the muscles in that area are compressed and tense, leading to poor blood circulation, accumulation of metabolic products, and easy fatigue and soreness. If the user has plantar fasciitis or muscle strain after exercise, the temperature in a certain area of the foot will rise due to congestion and inflammation.
[0038] Because of the collapsed arch in flat feet, the midfoot area is subjected to constant pressure, leading to prolonged traction and fatigue in this area. High arches, on the other hand, concentrate pressure on the forefoot and heel, resulting in poor cushioning, gait rigidity, and increased susceptibility to strain on local hard tissues. Therefore, combining foot type characteristics with temperature distribution data analyzed using a target recognition algorithm model can determine the user's foot condition. By analyzing the pressure and temperature distribution data of the sole and comparing the determined foot features with a pre-established foot type feature database, the user's foot type and condition can be accurately determined, facilitating the provision of appropriate massage techniques.
[0039] Step S300: Control the foot massage device to work based on the user's foot type and foot condition.
[0040] In step S300, as Figure 5 As shown, the specific steps include: Step S311: In response to the user's foot type being flat feet, control the massage module of the midfoot area 200 to roll at the first level, and control the heating module of the midfoot area 200 to work in constant temperature mode; the constant temperature mode means that during the operation of the heating module, the temperature of the heating module is maintained within a preset temperature range. Step S312: Control the massage modules of the forefoot area 100 and the hindfoot area 300 to perform tapping and / or kneading at the second setting; Step S313: During the operation of the foot massage device, if the pressure in the midfoot area 200 is greater than the preset pressure threshold, the rolling pressure of the massage module is reduced.
[0041] In this embodiment, the working modes of the massage module include kneading, rolling and patting, and the adjustment levels of the massage module include a first level, a second level and a third level. The pressure value of the first level is less than the pressure value of the second level, and the pressure value of the second level is less than the pressure value of the third level. The working modes of the heating module include constant temperature mode, incremental mode, intermittent mode and alternating mode.
[0042] When a user has flat feet, the massage intensity of the midfoot area 200 needs to be reduced to prevent overstimulation. Therefore, continuous, low-temperature heat therapy can be used to promote fascia relaxation. The control unit controls the massage module of the midfoot area 200 to roll at the first level and controls the heating module of the midfoot area 200 to operate in a constant temperature mode. For example, the massage head of the midfoot area 200 can be controlled to roll on the user's sole with a force of 2.5N, and the temperature of the heating module is maintained between 37℃ and 39℃ during the operation of the heating module to provide continuous low-temperature heat therapy to the midfoot area 200. During the operation of the heating module, temperature compensation is also performed based on the temperature changes of the sole detected by the infrared temperature sensor; if a certain area of the sole heats up too quickly, the control unit can temporarily switch the constant temperature mode to an intermittent mode to prevent that area from becoming too hot and affecting the user experience.
[0043] The massage modules controlling the forefoot region 100 and the hindfoot region 300 perform tapping and / or kneading at the second setting. For example, the massage heads controlling the forefoot region 100 and the hindfoot region 300 tap and / or knead with a force of 4.5N to massage the forefoot and heel. During the operation of the foot massage device, the pressure sensor in the midfoot region 200 collects the plantar pressure in the midfoot region 200 in real time and compares the plantar pressure in the midfoot region 200 with a preset pressure threshold. When the pressure in the midfoot region 200 is greater than the preset pressure threshold, the rolling pressure of the massage module is reduced, appropriately decreasing the force applied by the massage head to the sole of the foot, thereby avoiding compression of the plantar nerves.
[0044] like Figure 6 As shown, in one embodiment, step S300 further includes the following steps: Step S321: In response to the user's foot shape being a high arch, control the massage modules of the forefoot area 100 and the hindfoot area 300 to perform rolling and / or kneading at the third level, and control the heating module to work in a progressive mode; the progressive mode is that the temperature of the heating module gradually increases during the operation of the heating module. Step S322: Control the massage module of the midfoot area 200 to roll at the first level; Step S323: During the operation of the foot massage device, if the temperature fluctuation of the sole corresponding to the forefoot area 100, midfoot area 200 or rearfoot area 300 is greater than or equal to the target temperature, the heating module of the current area is controlled to switch to intermittent mode; the intermittent mode is when the heating module switches between working state and stop state during the operation of the heating module. Step S324: If the temperature fluctuation of the sole of the foot is less than the target temperature, then control the heating module to continue working.
[0045] In this embodiment, when the user has a high arch, greater pressure needs to be applied to the forefoot and heel to promote blood circulation in the sole and relieve concentrated pressure; while less pressure is applied to the midfoot area 200 to avoid nerve compression. Therefore, the massage modules in the forefoot area 100 and the hindfoot area 300 are controlled to roll and / or knead at the third setting, and the heating module is controlled to operate in a progressive mode. For example, the massage heads in the forefoot area 100 and the hindfoot area 300 are controlled to roll and / or knead the user's sole with a force of 6.5N to enhance the tactile sensation of the sole; during the operation of the heating module, the temperature of the heating module is gradually increased, starting at 38°C and gradually rising to 43°C to achieve continuous heating of the heating modules in the forefoot area 100 and the hindfoot area 300. Since peripheral circulation is poor in high arches, if the user's foot temperature remains low, the heating time or peak temperature of the heating module can be increased by the control unit to meet the usage needs of high arch foot types. The massage module in the midfoot area 200 is further controlled to roll at the first setting; for example, the massage head in the midfoot area 200 is controlled to roll against the user's sole with a force of 2.5N to avoid overstimulation of the sole corresponding to the midfoot area 200. Furthermore, a pressure feedback loop is provided within the massage module. If the pressure feedback loop detects and reports that there is no relief after prolonged pressure on the forefoot, the control unit can automatically increase the pressure applied by the massage head to the sole to meet the stimulation needs of the foot muscles.
[0046] During the operation of the foot massage device, infrared temperature sensors in the forefoot area 100, midfoot area 200, and rearfoot area 300 collect the temperature of their respective areas in real time and analyze the temperature fluctuations of the soles in each area. The temperature fluctuations are compared with the target temperature. If the temperature fluctuation in any of the forefoot area 100, midfoot area 200, or rearfoot area 300 is greater than or equal to the target temperature, the heating mode for that area is switched to intermittent mode, stopping the heating module from working and preventing burns to the user's feet due to excessively rapid temperature rise, thus affecting the user experience. If the temperature fluctuation is less than the target temperature, the heating module continues to work to provide continuous heat therapy to the soles of the feet, meeting the user's needs. The target temperature can be 0.3℃, 0.4℃, 0.5℃, 0.6℃, 0.7℃, etc., and can be set according to actual usage requirements.
[0047] like Figure 7 As shown, in one embodiment, step S300 further includes the following steps: Step S331: In response to the user's foot shape being a normal foot shape, control the massage modules of the forefoot area 100, midfoot area 200 and hindfoot area 300 to knead, roll or pat at any level, and control the heating module to work in an alternating mode; the alternating mode is that during the operation of the foot massage device, the heating modules of the hindfoot area 300, midfoot area 200 and forefoot area 100 work alternately in sequence; Step S332: During the operation of the foot massage device, the user's foot position is detected. In response to the user's foot position not being in the preset foot position, the massage module and heating module are controlled to stop working and the current position of the foot is calibrated.
[0048] In this embodiment, when the user has a normal foot shape, the pressure on the sole of the foot is relatively even, and the entire sole is suitable for kneading, rolling, or patting. Furthermore, alternating hot compresses are applied to different areas to enhance blood flow throughout the sole and relieve foot fatigue. The massage modules in the forefoot area 100, midfoot area 200, and rearfoot area 300 can be controlled to knead, roll, or pat at any setting. For example, the massage heads in the forefoot area 100, midfoot area 200, and rearfoot area 300 can be controlled at the second setting, such as 4.5N, to knead, roll, or pat the entire sole. Users can also adjust the force applied by the massage heads according to their actual needs to better meet the requirements of different users and to be suitable for more application scenarios. Then, the heating modules in each area are controlled to work alternately. First, the heating module in the rearfoot area 300 is controlled to work, while the heating modules in the midfoot area 200 and the forefoot area 100 are controlled to stop working. When the heating module in the rearfoot area 300 meets the working requirements, such as meeting the working time or reaching the target heating temperature, it is controlled to stop working, and the heating module in the midfoot area 200 is controlled to work. Then, after the heating module in the midfoot area 200 meets the working requirements, the heating module in the forefoot area 100 is further controlled to work, so that the heating modules in the forefoot area 100, midfoot area 200 and rearfoot area 300 work alternately to enhance blood flow in the entire sole of the foot and relieve foot fatigue.
[0049] During operation, pressure sensors and infrared temperature sensors collect real-time pressure and temperature distribution data across the entire sole of the foot, determining the user's foot position based on this data. The user's current foot position is compared to a preset position. If the user's current foot position is not in the preset position, the massage and heating modules stop working, and the foot's position is calibrated to ensure it is correctly positioned. This provides a better massage experience and reduces safety hazards when using the foot massage device.
[0050] like Figure 3 As shown, in one embodiment, after step S200 and before step S300, the following steps are further included: Step S230: Calculate the offset of the user's foot position based on pressure distribution data and temperature distribution data; Step S240: In response to the offset exceeding the set threshold, generate an alert command; Step S250: Based on the reminder instruction, remind the user to adjust the position of their feet; Step S260: After reminding the user to adjust their foot position to meet the preset time, if the user's foot position is not adjusted to the preset foot position, the foot massage device will stop working.
[0051] In this embodiment, the foot massage device presets a standard foot position model, i.e., preset foot position. When the user places their foot into the foot massage device, the sensor module collects real-time pressure distribution data and temperature distribution data, and calculates the specific offset of the user's foot position based on the pressure distribution data and temperature distribution data, providing an accurate basis for subsequent judgment on whether the user's foot position is reasonable.
[0052] After calculating the user's foot position offset, the offset is compared with a set threshold. If the offset is less than the threshold, the user's current foot position is considered not to affect the massage effect, and no reminder command needs to be generated. If the offset is greater than the threshold, the correspondence between the user's current foot position and the massage and heating modules is relatively disordered, and the massage and heating modules cannot provide a good massage effect for the user's feet, and there may also be safety hazards. Therefore, the control unit generates a reminder command to remind the user to adjust the current foot position. The reminder command can be a voice reminder, indicator light reminder, tactile reminder, or graphical interface reminder. A voice reminder alerts the user to a sound indicating a foot position offset. An indicator light reminder involves flashing indicator lights around the foot cavity; for example, a flashing red light indicates a foot position offset, while a solid green light indicates a correct foot position. A tactile reminder involves a slight vibration of the massage head in the corresponding offset area; for example, if the left foot is off to the left, the massage head on the left side of the left foot cavity vibrates, prompting the user to adjust in the opposite direction. A graphical interface reminder displays the specific position of the foot on the foot massage device's display interface, along with a preset foot position, to remind the user of the current foot position offset.
[0053] After reminding the user to adjust their foot position for the preset time, if the user's foot position has not yet been adjusted to the preset position, the foot massage device can be stopped by the control unit. This allows the user time to adjust and avoids ineffective massage or potential injury caused by improper foot positioning. The preset time can be 5s, 6s, 7s, 8s, 9s, 10s, etc., and can be set according to actual needs.
[0054] like Figure 4 As shown, in one embodiment, step S230 includes the following steps: Step S231: Identify the user's foot contact area based on temperature distribution data; Step S232: In response to missing temperature data in the foot contact area, determine the user's foot position offset; Step S233: Based on the pressure distribution data in the forefoot region 100 and the hindfoot region 300, identify the position of the user's toes and heels, and determine the current position of the foot; Step S234: Based on the current position of the foot and the preset foot position, calculate the deviation between the current position of the foot and the preset foot position to obtain the offset of the foot position.
[0055] In this embodiment, after the infrared temperature sensor collects the temperature distribution data of the sole of the foot in real time, it can analyze and identify the contact area of the user's foot at the preset foot position on the foot massage device; and determine whether the temperature data of the foot is missing. If the temperature data of the foot contact area is missing, it indicates that the user's foot is not in the preset foot area, and it is determined that the user's foot position is off; for example, if there is no data in the midfoot area, it means that the user's foot is not placed in the core recognition area, or the foot is only half inserted into the foot cavity, or the user's foot is suspended in the air.
[0056] Further, based on the pressure distribution data within the forefoot region 100 and the hindfoot region 300, the positions of the user's toes and heels are identified. Since the pressure distribution in different parts of the foot has distinct characteristics, the toes generate dispersed point pressure, while the heels generate concentrated block pressure. In the pressure distribution data of the forefoot region 100, areas with higher pressure values and dispersed point distribution are identified and marked as toe positions. In the pressure distribution data of the hindfoot region 300, areas with the highest pressure values and concentrated block distribution are identified and marked as heel positions. This determines the positions of the user's toes and heels, and further, the current position of the entire foot can be determined.
[0057] The current foot position is compared with a preset foot position, and the deviation between the two positions, such as lateral and longitudinal offset, is calculated. This provides a clear threshold for determining whether to trigger a reminder command. Temperature distribution data is used for initial analysis to check for foot displacement. Then, pressure distribution data is used to determine the positions of the user's toes and heels to ascertain the current foot position. Comparing the current foot position with the preset foot position allows for the calculation of the offset, prompting the user to adjust their foot position and thus providing a better massage experience.
[0058] When a user's foot shifts, the pressure and temperature distribution data of the sole may be missing or distorted; for example, there may be no data in the midfoot area or abnormal pressure distribution on the sole. If the foot massage device is still operated, it may pose a safety hazard and affect the user experience.
[0059] like Figure 8 As shown, in one embodiment, the following steps are included after step S300: Step S400: During the operation of the foot massage device, continuously collect pressure distribution data and temperature distribution data of the user's soles in various areas; Step S500: Based on pressure distribution data and temperature distribution data, update the user's foot condition in real time; Step S600: Based on the updated foot condition, adjust the working modes of the massage module and the heating module.
[0060] In this embodiment, during the operation of the foot massage device, pressure sensors and infrared temperature sensors continuously collect pressure and temperature distribution data in real time within the forefoot area 100, midfoot area 200, and hindfoot area 300. This data is constantly updated to reflect changes in pressure and temperature across the soles of the feet, determining whether foot pressure has changed, whether the temperature has reached a comfortable level, and whether any area of the sole is overheating. Continuously collecting dynamic changes in foot pressure and temperature provides a basis for subsequent adjustments.
[0061] By analyzing pressure and temperature distribution data, the system updates the user's foot condition in real time. For example, if the initial pressure in the forefoot is concentrated, and after the massage head has been working for a period of time, the pressure in the forefoot area 100 disperses and decreases, it indicates that the forefoot muscles have relaxed. If the temperature in the midfoot area 200 rises from 30℃ to 38℃, it means that the user's feet have reached a comfortable temperature. If the temperature in a certain area of the foot exceeds 43℃, it means that the foot may be about to overheat, which may cause the user's feet to feel burning.
[0062] Further adjustments to the operating modes of the massage and heating modules are made based on updated foot conditions. For example, if pressure distribution data shows that forefoot pressure is still high and forefoot muscles are not fully relaxed, the pressure intensity of the massage heads in that area can be increased or the rotation frequency increased. If pressure distribution data shows that overall pressure has significantly decreased and foot muscles have relaxed, the massage intensity can be automatically reduced to avoid overstimulation. If temperature distribution data shows that the midfoot area (200°C) has not reached the preset comfortable temperature, the power of the heating module can be increased to accelerate heating. If the temperature reaches a comfortable value and is relatively stable, the power of the heating module can be reduced to maintain a constant temperature and avoid energy waste. If the temperature in a certain area rises rapidly, the heating module in that area is shut off to prevent localized overheating. By adjusting the operating modes of the massage and heating modules based on updated foot conditions, overheating or overpressure can be effectively prevented, improving the comfort and safety of the foot massage device.
[0063] In summary, the control method and foot massage device provided in this embodiment of the invention accurately identify the user's foot type and condition through data acquisition from pressure sensors and infrared temperature sensors. Based on the user's foot type and condition, it provides massage and heat therapy solutions that better match the structural characteristics of the foot, improving the adaptability of the foot massage device. Massage modules and heating modules are provided in the forefoot area 100, midfoot area 200, and rearfoot area 300, enabling independent control of massage and heating of the forefoot, arch, and heel, making the stimulation more closely aligned with key pressure points and fascia locations. Furthermore, the massage modules have multiple working modes and multiple intensity levels. The control unit can switch working modes and adjust intensity levels in real time according to the pressure distribution in the midfoot, forefoot, and heel areas to meet the muscle stimulation needs of different foot types. During the massage process, changes in foot pressure and temperature are dynamically sensed, and the intensity of the massage head and the temperature of the heating module are adjusted in real time to prevent overheating or overpressure, improving the comfort and safety of the foot massage device.
