[0002] The massage instrument is a non-surgical device that can help relieve pain and alleviate discomfort.

[0003] In particular, the massage instrument using electrodes for electric stimulation massage can adjust the output gear, control the output pulse of the electrodes, and thus control the output intensity through buttons, remote controls, APPs, etc.

[0004] In related technologies, after the massage instrument is turned on or the mode is switched, the gear setting mode of the massage instrument is the default lowest gear or the gear at the last shutdown.

[0005] However, for the default lowest gear, the user has to adjust from the lowest gear to the desired gear every time after turning on or switching the mode, which is frequent operation and poor user experience.

[0006] For the default gear at the last shutdown, i.e., the memory gear, since the user's situation is different every time, it is difficult to ensure that the memory gear last time is the gear suitable for the current situation, and if the memory gear is relatively high, it is easy to cause pain in the initial wearing or dry skin condition, affecting the user experience.

[0107] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0108] Please see Figure 1 As shown, the present invention provides a preferred embodiment of a method for adjusting the intensity of an electrical stimulation massage device.

[0109] The electrostimulation massage device includes an impedance detection module and an electrode assembly for outputting electrical pulse signals. When the electrode assembly is in contact with human skin and outputs electrical pulse signals to the human body, the impedance detection module acquires the human body impedance value. The electrode assembly includes paired electrodes that are in contact with human skin. The human body impedance value refers to the impedance value between the paired electrodes when the electrode assembly is in contact with human skin for electrostimulation massage.

[0110] Because the human body's impedance value is constantly changing due to various factors such as the degree of contact between the electrode components and the skin, the dryness of the skin, and the duration of wearing the electrical stimulation massage device, the appropriate massage level may vary each time the electrical stimulation massage device is worn.

[0111] To enhance user experience, the electrostimulation massage device of this invention automatically enters an intelligent intensity adjustment mode upon power-on. In this mode, the massage intensity level adaptively adjusts to the optimal level that matches the user's current impedance value, reducing the need for frequent intensity adjustments during wear.

[0112] The method for adjusting the intensity level of the electrical stimulation massage device of the present invention includes the following steps:

[0113] When the preset trigger conditions are met, the gear intelligent adjustment mode is entered;

[0114] In intelligent voltage adjustment mode, the voltage level is adjusted to the corresponding target level based on the current human body impedance value;

[0115] The control electrode assembly outputs an electrical pulse signal corresponding to the target gear position.

[0116] Specifically, the electrical stimulation massage device has pre-set voltage levels that the human body adapts to at different impedance values. Under different voltage levels, the electrode assembly outputs different electrical pulse signals corresponding to that voltage level.

[0117] After the electrical stimulation massage device is turned on and enters the intelligent adjustment mode, the impedance detection module detects the human body's impedance value, and the electrical stimulation massage device adjusts the voltage level, taking the target level corresponding to the current human body impedance value as the current voltage level. The electrode assembly then outputs an electrical pulse signal corresponding to the current voltage level, i.e., the target level. This allows the massage level to be adaptively adjusted to match the user's current impedance value after the device is turned on, thereby reducing the need for frequent level adjustments when the user is wearing the device and also avoiding stinging.

[0118] The impedance detection module can detect the human body impedance value in real time or periodically.

[0119] Real-time detection allows the gear level to change in real time according to changes in human body impedance, resulting in high adjustment accuracy; periodic detection can slow down the rate at which the gear level changes with human body impedance, thus meeting different user habits.

[0120] In one embodiment, the preset trigger adjustment can be a power-on signal, that is, when a power-on signal is detected / received, the gear intelligent adjustment mode is entered.

[0121] It should be noted that the above method also applies to scenarios involving massage mode switching. As mentioned, the preset trigger adjustment can be a massage mode switching signal, meaning that upon detecting / receiving a massage mode switching signal, the system enters the intelligent intensity adjustment mode. This allows the massage intensity to adaptively adjust to match the user's current impedance value during massage mode switching, thereby reducing the need for frequent intensity adjustments and preventing stinging.

[0122] In particular, the above method is more suitable when the user switches massage modes within a preset time after powering on, before the electrical stimulation massage device has entered a steady-state massage state.

[0123] In a preferred embodiment, considering that intelligent adjustment may sometimes fail to meet user needs, for example, some users prefer manual adjustment, it is necessary to determine whether the user has manually adjusted the gear before entering the intelligent gear adjustment mode. Please refer to [link to relevant documentation]. Figure 1 The specific judgment method is as follows:

[0124] After receiving the trigger signal, wait for the first preset time;

[0125] If no manual gear adjustment signal is detected within the first preset time, the gear intelligent adjustment mode will be entered.

[0126] If a manual gear adjustment signal is detected within the first preset time, the manual adjustment mode will be entered.

[0127] That is, a certain waiting time is preset in the electrical stimulation massage device, namely the first preset time. If the user manually adjusts the massage level within this waiting time, the device enters the manual adjustment mode; otherwise, it enters the intelligent level adjustment mode.

[0128] In manual adjustment mode, the voltage level can be adjusted to the corresponding manual level based on the current manual adjustment level signal, controlling the electrode assembly to output an electrical pulse signal corresponding to the manual level. For example, manually selecting the level to 2V will output an electrical pulse signal with a 2V amplitude. To increase the intensity, the level can be manually switched to 5V, which will output an electrical pulse signal with a 5V amplitude.

[0129] Specifically, the trigger signal can be a power-on signal. That is, the step of entering the intelligent gear adjustment mode when the preset trigger conditions are met includes: after receiving the power-on signal, waiting for a first preset time; if no manual gear adjustment signal is detected within the first preset time, entering the intelligent gear adjustment mode; if a manual gear adjustment signal is detected within the first preset time, entering the manual adjustment mode.

[0130] The trigger signal can also be a massage mode switching signal. That is, the step of entering the intelligent gear adjustment mode when the preset trigger conditions are met includes: after receiving the massage mode switching, waiting for a first preset time; if no manual gear adjustment signal is detected within the first preset time, then entering the target massage mode with the default gear as the gear determined by the intelligent gear adjustment mode; if a manual gear adjustment signal is detected within the first preset time, then entering the target massage mode with the default gear as the gear determined by the manual gear adjustment mode.

[0131] In this way, after powering on or switching modes, the user can determine the gear adjustment method according to their preferences.

[0132] In one embodiment, if the user does not manually adjust the voltage level immediately after powering on, and the electrical stimulation massage device has already entered the intelligent voltage level adjustment mode but then receives a signal from the user to manually adjust the voltage level, it enters the manual adjustment mode. Based on the current manual adjustment signal, the voltage level is adjusted to the corresponding manual level, and the control electrode assembly outputs an electrical pulse signal corresponding to the manual level. That is, the manual adjustment mode always has a higher priority than the intelligent voltage level adjustment mode to meet the user's need for manual adjustment at any time.

[0133] In a preferred embodiment, to provide the user with a sufficiently safe experience, the step of adjusting the voltage level to the corresponding target level according to the current human body impedance value in the intelligent level adjustment mode, and controlling the electrode assembly to output an electrical pulse signal corresponding to the target level is as follows:

[0134] After entering the intelligent voltage adjustment mode, adjust the voltage level to the initial safe level.

[0135] The voltage level is gradually increased as the body's impedance decreases.

[0136] When the human body impedance value decreases to a preset value, the voltage level is adjusted to the corresponding target level according to the current human body impedance value, and the control electrode assembly outputs an electrical pulse signal corresponding to the target level.

[0137] Specifically, for safety reasons, upon entering the intelligent voltage adjustment mode, the voltage level is not directly adapted to the current human body impedance value. Instead, it is first adjusted to the initial safe level, which typically corresponds to a relatively weak voltage value. As the wearer adjusts their posture and the wearing time increases, the human body impedance value gradually decreases, and the voltage level gradually increases until the human body impedance value reaches the standard. At this point, the voltage level is officially adapted to the current human body impedance value to control the electrical pulse output of the electrode components. This method ensures safe use, especially during the initial power-on process.

[0138] In a preferred embodiment, besides needing a more convenient way to find the suitable massage level when powering on, it is also necessary to easily find the suitable massage level for each massage mode after switching between different massage modes during wear. Therefore, the electrical stimulation massage device also enters an intelligent level adjustment mode when it receives a massage mode switching signal. Several different embodiments are described below for the specific level adjustment methods during massage mode switching; please refer to [link / reference]. Figure 2 .

[0139] In one embodiment, the method for adjusting the intensity level of an electrical stimulation massage device, after the step of controlling the electrode assembly to output an electrical pulse signal corresponding to a manual intensity level, or after the step of controlling the electrode assembly to output an electrical pulse signal corresponding to a target intensity level, further includes the step of: when a massage mode switching signal is detected, restoring the voltage intensity level to the default safe intensity level and then entering the target massage mode.

[0140] Specifically, regardless of whether the electrical stimulation massage device is in manual adjustment mode or intelligent intensity adjustment mode, it will detect whether the user has switched massage modes. To ensure the user's safety immediately after switching massage modes, the electrical stimulation massage device has a preset default safety intensity level. When a massage mode switching signal is detected, the voltage intensity level is first restored to the default safety intensity level before entering the target massage mode, that is, entering the target massage mode with the default intensity level as the default safety intensity level.

[0141] Before switching massage modes, the device is either in manual adjustment or intelligent voltage adjustment mode. Upon detecting a massage mode switching signal and restoring the voltage level to the default safe level, it enters intelligent voltage adjustment mode. This is because the voltage value at the default safe level is very low, resulting in very weak sensory perception on the body, and therefore, this level typically cannot meet the user's massage needs. The aforementioned default safe level can be one of the following: primary level, zero voltage level, safe voltage level, or user-defined level.

[0142] Before switching massage modes, the device is in manual adjustment mode. If no massage mode switching signal is detected, it waits for a preset time. If no manual adjustment signal is detected within the preset time, the control electrode assembly outputs an electrical pulse signal corresponding to the current manual adjustment level. If a manual adjustment signal is detected within the preset time, the control electrode assembly outputs an electrical pulse signal corresponding to the adjusted manual adjustment level.

[0143] Before switching massage modes, the device is in intelligent gear adjustment mode. If no massage mode switching signal is detected, it waits for a preset time. If no manual gear adjustment signal is detected within the preset time, the control electrode assembly outputs an electrical pulse signal corresponding to the current target gear. If a manual gear adjustment signal is detected within the preset time, the control electrode assembly outputs an electrical pulse signal corresponding to the adjusted manual gear.

[0144] That is, if the user does not switch modes, the gear will be adjusted according to the original mode until the user manually adjusts the gear again, at which point the control electrode assembly will output the corresponding electrical pulse signal according to the manually adjusted gear.

[0145] In one embodiment, the method for adjusting the intensity level of an electrostimulation massage device, after the step of controlling the electrode assembly to output an electrical pulse signal corresponding to a manual intensity level, or after the step of controlling the electrode assembly to output an electrical pulse signal corresponding to a target intensity level, further includes the steps of: when a massage mode switching signal is detected, waiting for a second preset time; if no manual intensity level signal is detected within the second preset time, then entering the target massage mode in an intelligent intensity level adjustment mode; and / or, if a manual intensity level signal is detected within the second preset time, then entering the target massage mode at the intensity level corresponding to the manual intensity level signal.

[0146] Specifically, regardless of whether the electrical stimulation massage device is in manual adjustment mode or intelligent intensity adjustment mode, it will detect whether the user has switched massage modes. A certain waiting time, or second preset time, is preset in the electrical stimulation massage device. When a massage mode switching signal is detected, if the user manually adjusts the massage intensity within this waiting time, the target massage mode will be entered using the default intensity level determined by the manual adjustment signal; otherwise, the target massage mode will be entered using the default intensity level determined by the intelligent intensity adjustment mode.

[0147] For cases where the user does not switch massage modes, the same applies as the first embodiment listed above.

[0148] In one embodiment, the method for adjusting the intensity level of an electrostimulation massage device, after the step of controlling the electrode assembly to output an electrical pulse signal corresponding to a manual intensity level, or after the step of controlling the electrode assembly to output an electrical pulse signal corresponding to a target intensity level, further includes the following steps: when a massage mode switching signal is detected, the voltage intensity level is restored to the default safe intensity level and then the target massage mode is entered; within a third preset time after entering the target massage mode, if a manual adjustment intensity level signal is detected, the intensity level is adjusted to the intensity level corresponding to the manual adjustment intensity level signal; if no manual adjustment intensity level signal is detected, the intensity level is entered into an intelligent intensity level adjustment mode.

[0149] The default safety setting mentioned above can be one of the following: primary setting, zero voltage setting, safety voltage setting, or user-defined setting.

[0150] In this way, after the electrical stimulation massage device enters the target massage mode at the default safe setting, it determines whether to enter the intelligent adjustment mode to achieve adaptive adjustment of the massage level.

[0151] For cases where the user does not switch massage modes, the same applies as the first embodiment listed above.

[0152] In a preferred embodiment, when the electrical stimulation massage device is worn for a certain period of time, and the electrode assembly is stably attached to the human body and the skin condition is stable, the human body impedance value also tends to stabilize. At this time, the electrical stimulation massage device enters a steady-state massage state, and the electrical pulse signal output by the electrode assembly changes only slightly according to the human body impedance value.

[0153] Please see Figure 2 In the diagram, P1 and P2 represent the conditions before and after entering the steady-state massage state, respectively. In this preferred embodiment, after the step of satisfying the preset trigger condition and entering the intelligent gear adjustment mode, typically after the electrical stimulation massage device has been running for a period of time, that is, after the control electrode assembly outputs an electrical pulse signal corresponding to the manual gear, or after the control electrode assembly outputs an electrical pulse signal corresponding to the target gear, the gear adjustment method further includes:

[0154] After receiving the massage mode switching signal, determine whether the electrical stimulation massage device has entered a steady-state massage state;

[0155] If the electrical stimulation massage device enters a steady-state massage state, then the current level of the current massage mode is used as the default level to enter the target massage mode; or,

[0156] If the electrical stimulation massage device enters a steady-state massage state, the difference between the target massage mode and the current massage mode is obtained. Based on the difference and the current level of the current massage mode, the switching entry level is obtained, and the switching entry level is used as the default level to enter the target massage mode.

[0157] If the electrical stimulation massage device has not entered a steady-state massage state, the target massage mode can be entered in the manner described in the aforementioned gear adjustment method, such as by restoring the voltage level to the default safety level and then entering the target massage mode, by using the intelligent gear adjustment mode, or by manually adjusting the gear corresponding to the gear signal.

[0158] Specifically, when a user switches massage modes, the system first determines whether the electrical stimulation massage device has entered a steady-state massage state. The criteria for determining whether the device has entered a steady-state massage state are: whether the user's wearing time exceeds a preset duration, and whether the current human body impedance meets a preset stability condition. If both conditions are met simultaneously or any one of them is met, the device is considered to have entered a steady-state massage state. The preset stability condition can be that the current human body impedance value reaches a certain preset range, or that the difference between the human body impedance and the reference resistance is consistently less than a preset stability threshold after multiple consecutive measurements.

[0159] Based on the above judgment, if the electrical stimulation massage device enters a steady-state massage state, the current massage mode and current level will be maintained. For example, if the current massage mode is a soothing mode and the level is 3V, the 3V level will be maintained and the device will switch to a new massage mode.

[0160] Alternatively, based on the above judgment, if the electrical stimulation massage device enters a steady-state massage state, then the difference between the target massage mode and the current massage mode must first be obtained.

[0161] In different massage modes, the waveforms of the electrical pulses output by the electrode assembly are different, specifically in terms of pulse frequency and pulse amplitude. The difference can be a parameter derived from the difference in pulse frequency and the difference in pulse amplitude of the previous and subsequent waveforms, or a parameter derived from the difference in pulse frequency or the difference in pulse amplitude of the previous and subsequent waveforms respectively; or, the difference can be determined based on the similarity of the previous and subsequent waveforms.

[0162] After obtaining the difference between the target massage mode and the current massage mode, the difference value is combined with the value of the current level of the current massage mode. For example, the difference value is added to / multiplied by the value of the current level to obtain the level to switch into the target massage mode. Then, the level to switch into the target massage mode is used as the default level.

[0163] If, after the above assessment, the electrical stimulation massage device has not entered a steady-state massage state, then the target massage mode can be entered using the adjustment method described above. The fact that the electrical stimulation massage device has not entered a steady-state massage state indicates that the body's impedance value is still undergoing significant changes. This is usually due to changes in wearing conditions not reaching optimal levels, or insufficient wearing time for the body to adapt to the current, resulting in adaptive changes in impedance.

[0164] The following explanation continues on entering the target massage mode using the intelligent gear adjustment mode. In this case, if the intelligent gear adjustment mode is used, the voltage level can be matched to the current human body impedance value more quickly.

[0165] Furthermore, the electrical stimulation massage device can be preset for a certain time, namely the fourth preset time. The step of entering the intelligent gear adjustment mode if the electrical stimulation massage device has not entered the steady-state massage state includes: determining whether the user has manually adjusted the gear after receiving the massage mode switching signal for the fourth preset time. If no manual gear adjustment signal is detected, the intelligent gear adjustment mode is entered.

[0166] Accordingly, the specific steps for switching massage modes are as follows:

[0167] When a massage mode switching signal is detected, and the electrical stimulation massage device has not entered a steady-state massage state, wait for a fourth preset time. If the user does not manually adjust the massage level within the fourth preset time, the target massage mode will be entered in the intelligent level adjustment mode.

[0168] In a preferred embodiment, when a sudden change or irregular fluctuation in the human body impedance value is detected, the electrical stimulation massage device will automatically lower the intensity to reduce the stinging sensation that may be caused by poor contact of the electrode components and improve the user experience.

[0169] In this embodiment, the method for adjusting the intensity level of the electrical stimulation massage device specifically includes:

[0170] When the change in human body impedance exceeds the first change range threshold, or the change rate of human body impedance exceeds the change rate threshold, or when the human body impedance changes irregularly, it is determined to be an abnormal wearing condition.

[0171] Adjust the voltage setting to a safe level;

[0172] After adjusting the voltage level to the safe level, wait for the fifth preset time. If a manual adjustment signal is detected within the fifth preset time, enter the manual adjustment mode; otherwise, enter the intelligent adjustment mode.

[0173] The steps for determining irregular changes include:

[0174] Record the number of times the human body impedance value changes beyond the second threshold.

[0175] If the number of recorded times exceeds the qualitative change reference value within the preset change time, it is determined that the human body impedance value is changing irregularly.

[0176] Specifically, the electrical stimulation massage device is equipped with a first change amplitude threshold or change rate threshold, which is the reference range for allowing sudden changes in human impedance value; a second change amplitude threshold, which is the reference range for allowing irregular changes in human impedance value; and a qualitative change reference value, which is the reference number of times the human impedance value can change irregularly. The device detects the human impedance value and compares the current value with previous values. When the change amplitude of the human impedance value exceeds the first change amplitude threshold, or the change rate exceeds the change rate threshold, it indicates that the sudden change in the human impedance value has exceeded the allowable range. To avoid a sudden increase in the current applied to the body that could cause a stinging sensation, the voltage level is directly adjusted to a safe level, regardless of whether the electrical stimulation massage device is in automatic, manual, or stable massage mode.

[0177] Alternatively, the number of times the change in human body impedance exceeds the second threshold value can be recorded. If, within a certain time period, the number of recorded occurrences exceeds the value set for the qualitative change reference, it indicates that the human body impedance is undergoing irregular changes. Similarly, to avoid a sudden increase in the current applied to the human body that could cause a stinging sensation, the voltage level should be directly adjusted to a safe level, regardless of whether the electrical stimulation massage device is in automatic, manual, or stable massage mode.

[0178] Considering that users will usually manually operate the system to check and change the gear or massage mode if the gear suddenly drops during use, after adjusting the voltage level to a safe level, wait for a certain period of time, namely the fifth preset time; if no manual gear adjustment signal is detected within this time, the system will enter the intelligent gear adjustment mode; otherwise, it will enter the manual adjustment mode.

[0179] In a preferred embodiment, to implement the intensity adjustment methods of the foregoing embodiments, the electrical stimulation massage device further includes a control circuit. For example... Figure 3 , 4 As shown, the control circuit includes a power supply 100, a control unit 600, a boost circuit 200, and a pulse modulation circuit 300. The impedance detection module includes a first detection circuit 400 and a second detection circuit 500. The electrode assembly of the electrical stimulation massage device includes paired electrodes for attaching to the area of ​​the body to be massaged.

[0180] The boost circuit 200 is connected to both the control unit 600 and the power supply 100. Under the control of the control unit 600, the boost circuit 200 boosts the input voltage of the power supply 100 to a preset target voltage and outputs it through its output terminal. The power input terminal 311 of the pulse modulation circuit 300 is connected to the output terminal of the boost circuit 200. The first pulse transmission terminal and the second pulse transmission terminal of the pulse modulation circuit 300 are respectively connected to an electrode. The control terminal of the pulse modulation circuit 300 is connected to the control unit 600. The first detection circuit 400 is connected between the control unit 600 and the boost circuit 200. The control unit 600 obtains the output voltage of the boost circuit 200 through the first detection circuit 400. The second detection circuit 500 is connected to the control unit 600. The sampling resistor R1 of the second detection circuit 500 is connected in series between the pulse modulation circuit 300 and the ground terminal. The control unit 600 obtains the sampling voltage of the sampling resistor R1 through the second detection circuit 500.

[0181] When a user uses the electrical stimulation massage device, the electrodes are in contact with the human body, which is equivalent to connecting the human body impedance in series between the two electrodes, forming a loop in the pulse modulation circuit. The control unit 600 can obtain the impedance value between the paired electrodes, i.e., the human body impedance value, based on the output voltage of the boost circuit 200, the resistance value of the sampling resistor R1, and the sampling voltage.

[0182] Specifically, the boost circuit 200 is provided with a voltage input terminal, an output terminal and a control terminal, the pulse modulation circuit 300 is provided with a control terminal, a power input terminal 311, a ground terminal 312, a first pulse transmission terminal and a second pulse transmission terminal, the first detection circuit 400 includes a transmission terminal 420 and a detection terminal 410, the second detection circuit 500 also includes a transmission terminal 520 and a detection terminal 510, and the paired electrodes include a first electrode 301 and a second electrode 302.

[0183] In one embodiment, the boost circuit 200 is connected to the power supply 100 via a voltage input terminal, and the power supply 100 supplies power to the boost circuit 200. The boost circuit 200 is also connected to the power input terminal 311 of the pulse modulation circuit 300 via an output terminal, boosting the input voltage of the power supply 100 to a preset target voltage and transmitting it to the pulse modulation circuit 300 as the voltage value of the electrical pulse signal. The boost circuit 200 is also connected to the control unit 600 via a control terminal, and performs a boost operation under the control of the control unit 600 to boost the input voltage of the power supply 100 to the preset target voltage.

[0184] In one embodiment, the pulse modulation circuit 300 is first connected to the first electrode 301 and the second electrode 302 via a first pulse transmission terminal and a second pulse transmission terminal, respectively. The pulse modulation circuit 300 is also grounded via a ground terminal 312, which is equivalent to being connected to the negative terminal of the power supply 100. The control terminal of the pulse modulation circuit 300 is connected to the control unit 600. Under the control of the control unit 600, the voltage provided by the boost circuit 200 is modulated into a pulse signal, i.e., an electrical pulse signal. When the first electrode 301 and the second electrode 302 are conducting, the first pulse transmission terminal outputs an electrical pulse signal through the first electrode 301, and the second pulse transmission terminal receives the electrical pulse signal through the second electrode 302. The signal is then output through the ground terminal 312, forming a current loop. The control unit 600 controls the periodic switching of this loop through the control terminal of the pulse modulation circuit 300 to generate pulses. When a user uses the electrical stimulation massage device, the first electrode 301 and the second electrode 302 are attached to the part of the body to be massaged, achieving electrical conduction between the electrodes and the body. The electrical pulse signal is input to the part of the body to be massaged through the electrodes, allowing the user to experience electrical stimulation and form a massage sensation.

[0185] In one embodiment, both the first detection circuit 400 and the second detection circuit 500 are connected to the control unit 600 through their respective transmission terminals. The first detection circuit 400 is connected to the output terminal of the boost circuit 200 through its detection terminal, and the second detection circuit 500 is connected in parallel to the sampling resistor R1 through its detection terminal 510. The control unit 600 first obtains the voltage value at the output terminal of the boost circuit 200 through the first detection circuit 400, that is, the specific voltage value after the input voltage of the power supply 100 is boosted, thereby determining whether the preset target voltage has reached the expected value. The control unit 600 then obtains the sampling voltage on the sampling resistor R1 through the second detection circuit 500. Finally, the control unit 600 obtains the output voltage of the boost circuit 200 and the sampling voltage of the sampling resistor R1, and stores the resistance value of the sampling resistor R1. According to a preset algorithm, based on the output voltage, the resistance value of the sampling resistor R1, and the sampling voltage, the human body impedance value between the paired electrodes is obtained. Specifically, by obtaining the current flowing through the sampling resistor R1 using its resistance value and the sampling voltage, the current value of the electrical pulse signal of the pulse modulation circuit 300 can be obtained. The voltage value of the electrical pulse signal of the pulse modulation circuit 300 can be obtained through the output voltage. Based on the current and voltage values ​​of the electrical pulse signal, the total resistance value corresponding to the pulse modulation circuit 300 is obtained. This total resistance value is used as the impedance value between the paired electrodes. Alternatively, the impedance value between the paired electrodes can be obtained by subtracting the resistance value of the sampling resistor R1 from the total resistance value, or by subtracting the resistance value of the sampling resistor R1 from the total resistance value and then subtracting a preset error margin. The preset error margin can be the internal resistance generated by the wires or components of the pulse modulation circuit 300, the internal resistance generated by the electrode itself due to its material or shape, or the internal resistance generated at other different locations.

[0186] The control unit 600 acquires the human body impedance value in real time or periodically through the above operations, and adjusts the output voltage of the boost circuit 200 according to the impedance value, thereby adjusting the current of the electrical pulse signal of the pulse modulation circuit 300. In the intelligent adjustment mode, the control unit 600 adjusts the boost circuit 200 according to the current human body impedance value, so that it boosts the voltage output by the power supply to a preset target voltage corresponding to the target level, and outputs this voltage as the output voltage through the pulse generation circuit to the electrodes, so that the area to be massaged receives an electrical pulse signal adapted to the human body impedance value.

[0187] Therefore, the steps of adjusting the voltage level to the corresponding target level according to the current human body impedance value and controlling the electrode assembly to output an electrical pulse signal corresponding to the target level include: controlling the boost circuit to boost the voltage output by the power supply to the preset target voltage corresponding to the target level, so as to output the output voltage to the electrode assembly through the pulse generation circuit.

[0188] like Figure 5 As shown, the present invention provides a preferred embodiment of the second detection circuit 500.

[0189] The second detection circuit 500 also includes a first protective resistor R3, a first capacitor C1, and a first Zener diode D1. The control unit 600 is connected between the pulse modulation circuit 300 and the sampling resistor R1 through the first protective resistor R3. The control unit 600 is also connected between the sampling resistor R1 and ground through the first capacitor C1 and the first Zener diode D1, respectively. The anode of the first Zener diode D1 is grounded. Specifically, the two ends of the sampling resistor R1 are connected to the ground terminal 312 and the ground terminal of the pulse modulation circuit 300, respectively. The electrical energy output from the pulse modulation circuit 300 flows through the sampling resistor R1, and the voltage of the sampling resistor R1 is obtained by the control unit 600. By setting the first protective resistor R3 and connecting the control unit 600 and the sampling resistor R1, excessive voltage input to the control unit 600 is prevented, and voltage division is performed to effectively protect the control unit 600. By setting the first capacitor C1, the sampling signal is filtered to improve the accuracy of the sampling data. By setting the first Zener diode D1, preferably a Zener diode, voltage regulation is achieved.

[0190] In one embodiment, the second detection circuit 500 further includes a second protection resistor R3, which is connected in series between the pulse modulation circuit 300 and the sampling resistor R1. By setting the second protection resistor R3, the amount of electrical energy flowing into the control unit 600 is reduced, or voltage division is performed to reduce the voltage value input to the control unit 600, thereby protecting the entire second detection circuit 500.

[0191] like Figure 6 As shown, the present invention provides a preferred embodiment of the first detection circuit 400.

[0192] The first detection circuit 400 includes a first voltage divider resistor R4 and a second voltage divider resistor R5. The first voltage divider resistor R4 is connected to the output terminal of the boost circuit 200 and the second voltage divider resistor R5. The other end of the second voltage divider resistor R5 is grounded. The control unit 600 is connected to the connection node between the first voltage divider resistor R4 and the second voltage divider resistor R5 to obtain the voltage divided by the second voltage divider resistor R5. The control unit 600 obtains the output voltage of the boost circuit 200 based on the voltage divided by the second voltage divider resistor R5, the resistance value of the first voltage divider resistor R4, and the resistance value of the second voltage divider resistor R5.

[0193] Specifically, by utilizing the voltage division of the first voltage divider resistor R4 and the second voltage divider resistor R5, the output voltage of the boost circuit 200 is obtained by the first voltage divider resistor R4 and the second voltage divider resistor R5. Then, by reducing the value of the second voltage divider resistor R5, the control unit can directly obtain the voltage of the second voltage divider resistor R5 without the need for additional components for protection or current shunting. The first voltage divider resistor R4 should be much larger than the resistance value of the second voltage divider resistor R5. By reducing the voltage value of the second voltage divider resistor R5, and by knowing the resistance values ​​of the first voltage divider resistor R4 and the second voltage divider resistor R5, the control unit 600 can directly obtain the output voltage of the boost circuit 200.

[0194] In one embodiment, the first detection circuit 400 further includes a second capacitor, and the control unit 600 is connected to the connection node between the second voltage divider resistor R5 and the ground terminal through the second capacitor C2 for filtering.

[0195] like Figure 7(a) , 7(b) As shown, the present invention provides a preferred embodiment of a pulse modulation circuit 300.

[0196] The pulse modulation circuit 300 further includes at least one set of control arms, each including a first control switch 321 and a second control switch 324. The control unit 600 is connected to the control terminals of both the first and second control switches 321 and 324 respectively to control the on / off states of the first and second control switches 321. The input terminal of the first control switch 321 is connected to the power input terminal 311, and the output terminal of the second control switch 324 is connected to ground. The output terminal of the first control switch 321 is connected to one of the first and second pulse transmission terminals, and the input terminal of the second control switch 324 is connected to the other of the first and second pulse transmission terminals.

[0197] Specifically, when the boost circuit has a stable input voltage value and both electrodes are attached to the area to be massaged, the control unit 600 controls the on / off state of the first control switch 321 and the second control switch 324 to generate a pulse signal, i.e., an electrical pulse signal. The electrical energy input from the boost circuit passes sequentially through the first control switch 321, the first electrode 301, the area to be massaged, the second electrode 302, and the second control switch 324 before being output. This energy then flows through the sampling resistor R1 of the second detection circuit 500, stimulating the area to be massaged with the pulse current, allowing the area to experience a massage sensation. By adjusting the input voltage, the current passing through the area to be massaged can be adjusted to achieve different massage intensities. Combined with different pulse frequencies, different massage techniques can be achieved. The control unit 600 is connected to the first control switch 321 via control terminal 331 and to the second control switch 324 via control terminal 334.

[0198] In one embodiment, two sets of control arms are provided. The output terminals of two first control switches (321, 322) are respectively connected to the first pulse transmission terminal and the second pulse transmission terminal, and the input terminals of two second control switches (323, 324) are respectively connected to the first pulse transmission terminal and the second pulse transmission terminal. An H-bridge circuit is formed by the four control switches to realize the rapid control of the interactive switching of the two sets of control arms. The control unit 600 is connected to the first control switch 322 through control terminal 332 and to the second control switch 323 through control terminal 333.

[0199] In one embodiment, the first control switch (321, 322) and the second control switch (323, 324) are both transistors. Taking an H-bridge circuit as an example, removing two of the transistors creates a control arm. The circuit includes a first transistor Q1, a second transistor Q2, a third transistor Q3, and a fourth transistor Q4. The first transistor Q1 and the second transistor Q2 serve as the first control switches (321, 322), and the third transistor Q3 and the fourth transistor Q4 serve as the second control switches (323, 324). The emitters of both the first transistor Q1 and the second transistor Q2 are connected to the output of the boost circuit 200, serving as the power input terminal 311 of the pulse modulation circuit 300. The bases of both the first transistor Q1 and the second transistor Q2 are connected to the control terminal of the control unit 600. The collectors of both the first transistor Q1 and the second transistor Q2... The emitters of the first transistor Q1, the second transistor Q2, the third transistor Q3, and the fourth transistor Q4 are connected to the two electrodes respectively; the collectors of the third transistor Q3 and the fourth transistor Q4 are connected to the ground terminal 312 of the pulse modulation circuit 300. The bases of the third transistor Q3 and the fourth transistor Q4 are both connected to the control terminal of the control unit 600. The control unit 600 can control the switching on and off of the first transistor Q1, the second transistor Q2, the third transistor Q3, and the fourth transistor Q4 respectively. Preferably, it controls the simultaneous switching on and off of the first transistor Q1 and the fourth transistor Q4, and the simultaneous switching on and off of the second transistor Q2 and the third transistor Q3.

[0200] More specifically, the output of the boost circuit 200 is connected to the control unit 600 through a pull-up resistor to provide the voltage for driving the transistors to turn on and off. A resistor is connected in series with the base of each transistor to protect the control unit 600 and generate a driving voltage at the base to turn on the transistors. Both the first pulse transmission terminal and the second pulse transmission terminal are grounded through a bidirectional variable resistor diode (D2, D3), achieving bidirectional blocking between the motor and ground, facilitating current return to ground. Specifically, the power input terminal 311 of the pulse modulation circuit 300 is connected to the control unit 600 through resistor R10 and control terminal 331, through resistor R11 and control terminal 332, through resistor R12 and control terminal 333, and through resistor R13 and control terminal 334; and a resistor R6 is connected in series between control terminal 331 and the base of the first transistor Q1, a resistor R7 is connected in series between control terminal 332 and the base of the second transistor Q2, a resistor R8 is connected in series between control terminal 333 and the base of the third transistor Q3, and a resistor R9 is connected in series between control terminal 334 and the base of the fourth transistor Q4.

[0201] like Figure 8 As shown, the present invention provides a preferred embodiment of a boost unit 200.

[0202] In one embodiment, the boost circuit 200 includes a voltage input terminal 211 connected to the power supply 100, a voltage output terminal 251 connected to the pulse modulation circuit 300, and an inductor boost circuit 220, a capacitor energy storage circuit 230, and a voltage relief circuit 240 connected in series between the input terminal and the output terminal. The input terminal of the inductor boost circuit 220 is connected to the voltage input terminal 211, and the control terminal of the inductor boost circuit 220 is connected to the control unit 600; the input terminal of the capacitor energy storage circuit 230 is connected to the output terminal of the inductor boost circuit 220, and the output terminal of the capacitor energy storage circuit 230 is connected to the voltage relief circuit 240; the control terminal of the voltage relief circuit 240 is connected to the control unit 600, and the input terminal of the voltage relief circuit 240 is connected to the voltage output terminal 251.

[0203] The voltage input terminal 211 is used to input the voltage of the power supply 100. The inductor boost circuit 220 and the capacitor energy storage circuit 230 are used to receive the power supply voltage and store energy to achieve voltage boost. The voltage relief circuit 240 is used to divide the output voltage of the capacitor energy storage circuit 230 to achieve voltage reduction. The control unit 600 is used to control the energy storage of the capacitor energy storage circuit 230 and the voltage division of the voltage relief circuit 240, thereby controlling the voltage output terminal 251 of the voltage divider circuit 200 to output a variable voltage.

[0204] Therefore, in the intelligent adjustment mode, the control boost circuit 200 boosts the voltage output from the power supply 100 to the preset target voltage corresponding to the target level, and outputs it to the electrodes via the pulse modulation circuit 300 as the output voltage. This allows the voltage level to be adjusted to the corresponding target level based on the current human body impedance value, and the control electrodes output an electrical pulse signal corresponding to the target level. Specifically, the preset target voltage is determined based on the voltage corresponding to the target level; the inductor boost circuit and capacitor energy storage circuit are controlled to boost the voltage and / or the voltage relief circuit is controlled to reduce the voltage, thereby adjusting the output voltage of the boost circuit to the preset target voltage; the preset target voltage is output through the voltage output terminal 251 to the pulse modulation unit 300 to modulate the corresponding pulse signal, and the electrical pulse signal matched to the current human body impedance value can then be applied to the human body through the electrodes.

[0205] In one embodiment, the inductor boost circuit 220 includes an inductor PL1 and a MOSFET Q5. One end of the inductor PL1 is connected to the input terminal 211 of the inductor boost circuit 220. The gate of the MOSFET Q5 serves as the control terminal of the inductor boost circuit 220 and is connected to the control unit 600. The drain of the MOSFET Q5 is connected to the other end of the inductor PL1, and the voltage at this point serves as the output voltage of the inductor boost circuit 220. The source of the MOSFET Q5 is grounded.

[0206] Among them, MOSFET Q5 is mainly used as a current switching switch. The gate of MOSFET Q5 receives the control command from control unit 600 and turns on or off according to the control command from control unit 600. When MOSFET Q5 is turned on, inductor PL1 is grounded through MOSFET Q5, and current is generated inside inductor PL1 so that power supply 100 charges inductor PL1. When MOSFET Q5 is turned off, the current in inductor PL1 flows to capacitor energy storage circuit 230 to boost the voltage output by power supply 100.

[0207] The capacitor energy storage circuit 230 includes a first capacitor CE1 and a second capacitor C4 connected in parallel between the input terminal and the output terminal of the capacitor energy storage circuit 230, and the other end of the first capacitor CE1 and the second capacitor C4 is grounded.

[0208] Specifically, the first capacitor CE1 is mainly used for energy storage. When the MOSFET Q5 of the inductor boost circuit 220 is turned off, the current of the inductor PL1 flows to the first capacitor CE1 through the diode D1, so that the voltage output to the voltage output terminal 251 of the capacitor energy storage circuit 230 is the sum of the voltage of the inductor PL1 and the voltage of the first capacitor CE1, so as to achieve voltage boost; the second capacitor C4 is mainly used for small-amplitude voltage regulation to achieve voltage stabilization.

[0209] In one embodiment, the voltage relief circuit 240 is mainly used to reduce the voltage when the current output voltage from the capacitor energy storage circuit 230 to the voltage output terminal 251 is higher than a preset target voltage. The voltage relief circuit 240 includes a resistor R17, a transistor Q6, a resistor R16, and a resistor R18. Resistor R17 is connected in series between the control terminal of the voltage relief circuit 240 and the base of the transistor Q6, and the emitter of the transistor Q6 is grounded. One end of resistor R18 is connected between resistor R17 and the base of the transistor Q6, and the other end is grounded. Resistor R16 is connected in series between the input terminal of the voltage relief circuit 240 and the collector of the transistor Q6.

[0210] Specifically, when the output voltage of the capacitor energy storage circuit 230 to the voltage output terminal 251 is higher than the preset target voltage, the control unit 600 controls the transistor Q6 to turn on, and the voltage relief circuit 240 relieves the voltage of the inductor PL1 and the capacitor energy storage circuit 230, so that the output voltage of the capacitor energy storage circuit 230 to the voltage output terminal 251 is reduced to the preset target voltage, and the preset target voltage is output to the pulse modulation circuit 300 through the voltage output terminal 251.

[0211] Please see Figure 9 As shown, the present invention also provides a preferred embodiment of an electrostimulation massage device.

[0212] The electrical stimulation massage device includes an impedance detection module, an electrode assembly for outputting electrical pulse signals, and a control unit. The control unit is connected to both the impedance detection module and the electrode assembly to implement the intensity adjustment method described in the preceding embodiment.

[0213] The electrical stimulation massage device also includes a function key. The control unit is connected to the function key. After the function key is triggered, the control unit enters the intelligent adjustment mode of the gear level and controls the electrode assembly to output an electrical pulse signal corresponding to the current human body impedance value.

[0214] The function keys include either a power button or a massage mode switch button. The power button is used to start the electrical stimulation massage device, and the massage mode switch button is used to select different massage modes such as soothing mode and vitality mode.

[0215] After the above function keys are triggered, the control unit enters the intelligent gear adjustment mode and controls the electrode assembly to output an electrical pulse signal corresponding to the current human body impedance value.

[0216] The electrode assembly includes paired electrodes, an electrical stimulation circuit, and a boost circuit. The impedance detection module includes a feedback circuit. The electrodes are attached to the skin, and the electrical stimulation circuit applies electrical pulse signals to the body through the electrodes. The control unit is connected to both the boost circuit and the feedback circuit. The boost circuit outputs electrical pulse signals to the electrical stimulation circuit, and the feedback circuit receives the output voltage of the boost circuit and feeds it back to the control unit. The detection terminal of the impedance detection module is located in the electrical stimulation circuit. The detection terminal obtains the human body's impedance value based on the current flow of the electrical stimulation circuit, and the control unit adjusts the output voltage of the boost circuit based on the human body's impedance value. Thus, the electrical pulse signal applied to the body by the electrodes adaptively changes with the human body's impedance value.

[0217] The electrostimulation massage device also includes a speed adjustment button for users to manually adjust the intensity level. The speed adjustment button is connected to the control unit. After the electrostimulation massage device is turned on or a massage mode is switched, the control unit waits for a certain period, i.e., a first preset time. During this time, if the speed adjustment button does not transmit an adjustment signal to the control unit, the control unit enters the intelligent speed adjustment mode. In this mode, the control unit controls the electrodes to output an electrical pulse signal corresponding to the current human body impedance value. If the speed adjustment button transmits an adjustment signal to the control unit during this time, the control unit enters the manual adjustment mode. In this mode, the control unit controls the electrodes to output an electrical pulse signal corresponding to the current manual speed level.
