[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0030] The embodiments of the present application disclose a voltage adjustment method and an electrical stimulation massage device, which are used to improve the stability of the pulse voltage of the pulse waveform. The following will be described in detail respectively.

[0031] In order to better understand the embodiments of the present application, the related technologies will be described first below.

[0032] The electrical pulse technology has gradually penetrated from the original physical therapy field in hospitals to ordinary consumers, and more and more people have come into contact with electrical pulse massage devices. In recent years, the types, quantities, and sales of consumer-grade massage devices have increased rapidly. The demand of consumers for massage devices has changed from the original from scratch and small quantity of types to rich types. Especially in terms of experience, most users are more concerned about the massage effect of massage devices.

[0033] At present, due to the unstable pulse voltage of the massage device, sometimes the voltage is high and sometimes the voltage is low, resulting in more or less burrs in the pulse signal, so that there are more burrs in the output pulse waveform, and the stability of the pulse voltage is poor.

[0034] To solve the above technical problems, the present application discloses an electrostimulation massage device, which includes a memory, a processor, a feedback circuit, a voltage adjustment circuit, and an output circuit. The memory stores electrostimulation parameter data. The processor determines electrostimulation parameters for defining a corresponding periodically repeated modulation envelope according to the electrostimulation parameter data, and determines the current target voltage according to the modulation envelope. The output circuit outputs an electrical pulse signal according to the electrostimulation parameters. The feedback circuit detects the current output voltage of the output circuit. The processor determines the target operating parameters of the voltage adjustment circuit according to the difference between the current target voltage and the current output voltage. The voltage adjustment circuit operates according to the target operating parameters to adjust the voltage of the electrical pulse signal output by the output circuit. Different target operating parameters correspond to different voltage adjustment speeds. It can be seen that the electrostimulation massage device can determine the operating parameters of the voltage adjustment circuit according to the current target voltage and the current output voltage, and the voltage adjustment circuit can operate according to the determined operating parameters, so as to adjust the voltage of the electrical pulse signal output by the output circuit, make the output voltage close to or be the current target voltage, that is, make the absolute value of the difference between the output voltage and the current target voltage less than a very small threshold, which can improve the stability of the pulse voltage of the pulse waveform, and thus can improve the accuracy of voltage control.

[0035] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of an electrostimulation massage device disclosed in an embodiment of the present application. As Figure 1 shown, the electrostimulation massage device may include a memory, a processor, a feedback circuit, a voltage adjustment circuit, and an output circuit, where:

[0036] The processor is respectively connected to the memory, the feedback circuit, the voltage adjustment circuit, and the output circuit, and the output circuit is also respectively connected to the feedback circuit and the voltage adjustment circuit.

[0037] It should be understood that the above connections can be understood as electrical connections.

[0038] The memory stores electrostimulation parameter data. The processor can determine electrostimulation parameters for defining a corresponding periodically repeated modulation envelope according to the electrostimulation parameter data, and can determine the current target voltage according to the modulation envelope. The output circuit can output an electrical pulse signal according to the electrostimulation parameters. The feedback circuit can detect the current output voltage of the output circuit. The processor can determine the target operating parameters of the voltage adjustment circuit according to the difference between the current target voltage and the current output voltage. The voltage adjustment circuit operates according to the target operating parameters to adjust the voltage of the electrical pulse signal output by the output circuit. Different target operating parameters correspond to different voltage adjustment speeds.

[0039] The memory can be internal memory, a storage medium, or other components capable of storing information. The processor can be a Central Processing Unit (CPU), a MicroController Unit (MCU), or other processors. The output circuit is a circuit for outputting electrical pulse signals. The feedback circuit is a circuit for detecting the output voltage of the electrical pulse signals output by the output circuit. The voltage adjustment circuit is a circuit for adjusting the output voltage of the electrical pulse signals output by the output circuit.

[0040] The electrostimulation parameter data can include one or more first parameters, and these one or more first parameters are electrostimulation parameters for defining the corresponding periodically repeated modulation envelope. An electrical pulse signal can include one or more envelopes. An envelope can include one or more pulse signals. These one or more first parameters are electrostimulation parameters for defining the modulation envelope, that is, the parameters for determining the envelope.

[0041] The electrostimulation massage device can be a low-frequency device or a medium-frequency device. When the electrostimulation massage device is a low-frequency device, the electrical pulse signals output by the electrostimulation massage device are low-frequency electrical pulse signals. Exemplarily, in medicine, electrical pulse signals with a frequency below 1000 Hz are called low-frequency electrical pulse signals, and the method of using low-frequency electrical pulse signals to treat diseases is called low-frequency electrotherapy. When the electrostimulation massage device is a medium-frequency device, the electrical pulse signals output by the electrostimulation massage device are medium-frequency electrical pulse signals. Exemplarily, in medicine, electrical pulse signals with a frequency between 1000 Hz and 100,000 Hz are called medium-frequency electrical pulse signals, and the method of using medium-frequency electrical pulse signals to treat diseases is called medium-frequency electrotherapy.

[0042] When the electrostimulation massage device is a low-frequency device, these one or more first parameters can include one or more of the type of envelope, the lowest voltage, the highest voltage, the voltage rise time, the voltage fall time, and the operating time. The type of envelope is the type of voltage change of the envelope. The lowest voltage of the envelope is the minimum voltage of the envelope. The highest voltage of the envelope is the maximum voltage of the envelope. The type of envelope of the low-frequency electrical pulse signal can be types such as sine wave, triangular wave, sawtooth wave, constant voltage, rising hold, falling hold, etc. The voltage rise time (i.e., the rise time) of the envelope is the time for the voltage of the envelope to rise from the low voltage to the highest voltage. The voltage fall time of the envelope is the time required for the voltage of the envelope to fall from the high voltage to the lowest voltage. The operating time of the envelope is the duration of the voltage output of the envelope. Exemplarily, please refer to Figure 2 , Figure 2 is a schematic diagram of a low-frequency electrical pulse signal disclosed in an embodiment of the present application. As Figure 2As shown, the type of the envelope of the low-frequency electrical pulse signal is rising and holding. The voltage boost time of the envelope is the time required for the voltage of the envelope to rise from a low voltage to the highest voltage. The operating time of the envelope is the duration during which the voltage output of the envelope is not a low voltage.

[0043] When the electrostimulation massage device is an intermediate-frequency device, one or more of these first parameters may include one or more of the type of the envelope, the lowest voltage, the highest voltage, the frequency, and the number of executions. The frequency of the envelope is the number of times the envelope completes a periodic change per unit time. The number of executions of the envelope is the number of times the envelope is continuously executed.

[0044] Exemplarily, please refer to Figure 3 , Figure 3 is a schematic diagram of an intermediate-frequency electrical pulse signal disclosed in an embodiment of the present application. As Figure 3 shown, the type of the envelope of the intermediate-frequency pulse signal is a triangular wave. The intermediate-frequency electrical pulse signal includes two envelopes, and the frequencies of these two envelopes are different. Correspondingly, the periods T of these two envelopes are different. The number of executions of the first envelope is 9, and the number of executions of the second envelope is 10.

[0045] The electrostimulation parameter data may further include one or more second parameters, and one or more of these second parameters may include one or more of the pulse voltage, the pulse width, and the pulse frequency. The pulse frequency is the frequency of the pulse, which is the number of times the pulse completes a periodic change per unit time. The pulse frequency is set by the user. The pulse width may be the width of the pulse.

[0046] When the electrostimulation massage device is a low-frequency device, one or more of these second parameters may further include the waveform morphology and / or the pulse dead zone carrier information. The waveform morphology is the morphology of the pulse output. The waveform morphology may be single-sided output, alternating output, etc. Exemplarily, please refer to Figure 4 , Figure 4 is a schematic diagram of an alternating output waveform disclosed in an embodiment of the present application. The pulse dead zone carrier information may include the number of dead zones and the number of carriers. The number of dead zones is the number of dead zones. The dead zone is the region between a positive pulse and the next adjacent negative pulse. The number of carriers is the number of carriers. The carrier is the pulse in a cycle, which may include positive pulses and negative pulses. Exemplarily, please refer to Figure 5 , Figure 5 is a schematic diagram of another low-frequency electrical pulse signal disclosed in an embodiment of the present application. As Figure 5 shown, the number of dead zones of the low-frequency electrical pulse signal is 5, and the number of carriers is 5.

[0047] The processor may determine electrostimulation parameters for defining a corresponding periodically repeated modulation envelope according to the above one or more first parameters included in the electrostimulation parameter data. The electrostimulation parameters of the modulation envelope may include the rise and fall times of the modulation envelope, the minimum voltage of the modulation envelope, and the maximum voltage of the modulation envelope. The rise and fall times of the modulation envelope may include the rise time of the modulation envelope and / or the fall time of the modulation envelope. Depending on the type of the modulation envelope, the information included in the rise and fall times of the modulation envelope may be different. Exemplarily, when the type of the modulation envelope is rising hold, the rise and fall times of the modulation envelope include the rise time of the modulation envelope. Exemplarily, when the type of the modulation envelope is falling hold, the rise and fall times of the modulation envelope include the fall time of the modulation envelope. Exemplarily, when the type of the modulation envelope is triangular wave, the rise and fall times of the modulation envelope include the rise time of the modulation envelope and the fall time of the modulation envelope.

[0048] The output circuit may output an electrical pulse signal according to the electrostimulation parameters of the modulation envelope. The feedback circuit may detect the current output voltage of the output circuit. Meanwhile, the processor may determine the current target voltage according to the modulation envelope, and then may determine the target operating parameters of the voltage adjustment circuit according to the difference between the current target voltage and the current output voltage. The voltage adjustment circuit operates according to the target operating parameters to adjust the voltage of the electrical pulse signal output by the output circuit. It can be seen that the electrostimulation massage device may determine the operating parameters of the voltage adjustment circuit according to the required voltage and the output voltage of the output circuit. The voltage adjustment circuit may operate according to the determined operating parameters so as to adjust the voltage of the electrical pulse signal output by the output circuit, making the output voltage close to or equal to the required voltage, that is, making the absolute value of the difference between the output voltage and the current target voltage less than a very small threshold, which can improve the stability of the pulse voltage of the pulse waveform, thereby improving the accuracy of voltage control.

[0049] The voltage adjustment speed is different corresponding to different target operating parameters. Since the target operating parameter is determined by the difference between the current target voltage and the current output voltage, therefore, when the difference between the current target voltage and the current output voltage is different, the corresponding voltage adjustment speed is different. It can be seen that the voltage adjustment speed can be determined according to the difference between the current target voltage and the current output voltage. When the difference between the current target voltage and the current output voltage is larger, due to the large gap between them, in order to achieve voltage stability, a faster speed can be used to adjust the voltage, so that the output voltage can be quickly adjusted to the current target voltage or close to the current target voltage, and the absolute value of the difference between the output voltage and the current target voltage is less than a very small threshold, so as to reduce the voltage adjustment time. When the difference between the current target voltage and the current output voltage is smaller, due to the small gap between them, a slower speed can be used to adjust the voltage. It can be seen that when the difference between the current target voltage and the current output voltage is different, using different adjustment speeds to adjust the voltage can avoid using the same adjustment speed for adjustment, so that when the difference between the current target voltage and the current output voltage is large, the adjustment time is too long, and when the difference between the current target voltage and the current output voltage is small, the adjustment time is too short, which can improve the flexibility and applicability of voltage adjustment.

[0050] In some embodiments, the processor can determine the current target voltage according to the step-up / step-down time of the modulation envelope, the lowest voltage of the modulation envelope, and the highest voltage of the modulation envelope.

[0051] Since the current target voltage is determined according to the step-up / step-down time of the modulation envelope, the lowest voltage of the modulation envelope, and the highest voltage of the modulation envelope, therefore, when the adjustment envelopes are different, the determined current target voltages may be different.

[0052] The adjustment envelopes being different can mean that the step-up / step-down time of the modulation envelope is different, or the lowest voltage of the modulation envelope is different, or the highest voltage of the modulation envelope is different, or both the step-up / step-down time of the modulation envelope and the lowest voltage of the modulation envelope are different, or both the lowest voltage of the modulation envelope and the highest voltage of the modulation envelope are different, or both the step-up / step-down time of the modulation envelope and the highest voltage of the modulation envelope are different, or the step-up / step-down time of the modulation envelope, the lowest voltage of the modulation envelope, and the highest voltage of the modulation envelope are all different.

[0053] When the modulation envelopes are different, the massage techniques of the electrostimulation massage device are different. Therefore, the electrostimulation massage device can provide a variety of massage techniques for users by providing one or more different electrical pulse signals of the step-up / step-down time of the modulation envelope, the lowest voltage of the modulation envelope, and the highest voltage of the modulation envelope, which can enrich the massage techniques of the electrostimulation massage device, and thus can improve the user experience.

[0054] In addition, for the electrical pulse signals corresponding to different massage techniques, the electrical stimulation massage device can determine the current target voltage in real time or periodically according to the voltage boosting and dropping time, the minimum voltage of the modulation envelope, and the maximum voltage of the modulation envelope, so as to adjust the voltage of the electrical pulse signal output by the output circuit, making the voltage of the electrical pulse signal output by the output circuit close to or equal to the current target voltage, that is, making the absolute value of the difference between the output voltage and the current target voltage less than a very small threshold, which can improve the stability of the pulse voltage of the pulse waveform, thereby improving the accuracy of voltage control.

[0055] In some embodiments, the processor can first determine the step voltage according to the voltage boosting and dropping time, the minimum voltage of the modulation envelope, and the maximum voltage of the modulation envelope, and then determine the current target voltage according to the step voltage and the previous target voltage. The step voltage is the voltage adjustment amplitude per unit time.

[0056] The previous target voltage is the current target voltage determined last time.

[0057] The step voltage can be expressed as follows:

[0058] V step =(V max ―V min ) / T

[0059] where V step is the step voltage, V max is the maximum voltage of the modulation envelope, V min is the minimum voltage of the modulation envelope, and T is the voltage boosting and dropping time of the modulation envelope.

[0060] Exemplarily, assuming that the type of the modulation envelope is rising and holding, and T is the voltage boosting time of the modulation envelope. The current target voltage can be expressed as follows:

[0061] V target =V + V step

[0062] where V target is the current target voltage, and V is the previous target voltage.

[0063] Exemplarily, assuming that the type of the modulation envelope is falling and holding, and T is the voltage dropping time of the modulation envelope. The current target voltage can be expressed as follows:

[0064] V target =V - V step

[0065] Exemplarily, assume that the type of the modulation envelope is a triangular wave. During the rising stage of the triangular wave, the current target voltage can be determined in the same way as during the rising process, and during the falling stage of the triangular wave, the current target voltage can be determined in the same way as during the falling process.

[0066] It should be understood that the above is an exemplary description of determining the current target voltage based on the step voltage and the previous target voltage, and does not limit the specific implementation manner of determining the current target voltage based on the step voltage and the previous target voltage. Different types of modulation envelopes may result in different ways of determining the current target voltage based on the step voltage and the previous target voltage.

[0067] It can be seen that in the case where the envelope of the electrical pulse signal is determined, the step voltage will be determined. During the process of outputting the electrical pulse signal, the change in the voltage of the envelope changes according to the step voltage rather than suddenly, which can ensure a stable change in voltage, avoid sudden changes in voltage without a pattern, and thus avoid a poor user experience caused by voltage mutations, thereby improving the user experience.

[0068] In some embodiments, since the current target voltage may be greater than the current output voltage or less than the current output voltage, the processor can first determine the absolute difference between the current target voltage and the current output voltage, that is, determine the absolute value of the difference between the current target voltage and the current output voltage. Then, the processor can determine the target operating parameter corresponding to the absolute difference according to the correspondence between the difference interval and the operating parameter.

[0069] The memory can store the correspondence between the difference interval and the operating parameter. Since one difference interval corresponds to one operating parameter, the processor can first determine the target difference interval corresponding to the absolute difference, and then can determine the target operating parameter corresponding to the target difference interval according to the correspondence between the difference interval and the operating parameter.

[0070] Since one difference interval corresponds to one operating parameter, in the case where the absolute difference is within a difference interval, the corresponding target operating parameter is the same, which can reduce the number of changes in the operating parameters of the voltage adjustment circuit, reduce the number of voltage adjustments, and thus can reduce the power consumption of the electrostimulation massage device while ensuring voltage stability.

[0071] In some embodiments, since the current target voltage may be greater than the current output voltage or less than the current output voltage, the processor can determine the absolute difference between the current target voltage and the current output voltage. Then, the processor can determine the target operating parameter corresponding to the absolute difference according to the correspondence between the difference and the operating parameter.

[0072] The memory can store the correspondence between the difference value and the working parameter. Since one difference value corresponds to one working parameter, the processor can determine a working parameter for each difference value, which can ensure the timeliness of the voltage adjustment of the electrical pulse signal. When the output voltage is different from the current target voltage, the output voltage can be adjusted in a timely manner to make the output voltage close to or equal to the required voltage, that is, the absolute value of the difference between the output voltage and the current target voltage is less than a very small threshold value, which can improve the stability of the pulse voltage of the pulse waveform, thereby improving the accuracy of voltage control.

[0073] The correspondence between the difference value and the working parameter is a positive correlation. Therefore, the processor can accurately determine the target working parameter corresponding to the absolute difference value according to this positive correlation, which can improve the accuracy of the voltage control of the electrical pulse signal.

[0074] In some embodiments, the correspondence between the difference value and the working parameter is a proportional relationship. The processor can determine the target working parameter through the proportional relationship between the difference value and the working parameter, and can quickly adjust the output voltage of the electrical pulse signal as the absolute difference value changes, which can ensure the timeliness of the output voltage adjustment, thereby achieving precise control of the output voltage.

[0075] Exemplarily, the proportional relationship between the difference value and the working parameter can be y = kx. Wherein, y represents the working parameter, x represents the difference value, and k represents the proportionality coefficient.

[0076] The correspondence between the difference value and the working parameter can also be other positive correlation relationships.

[0077] In some embodiments, the voltage adjustment circuit can include a boost circuit and a buck circuit.

[0078] The boost circuit is a circuit for increasing the output voltage of the electrical pulse signal, that is, the boost circuit can increase the output voltage of the output circuit. The buck circuit is a circuit for reducing the output voltage of the electrical pulse signal, that is, the buck circuit can reduce the output voltage of the output circuit.

[0079] Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of another electrical stimulation massage device disclosed in the embodiments of the present application. As Figure 6 shown, the boost circuit is respectively connected to the processor and the output circuit, and the buck circuit is respectively connected to the processor and the output circuit.

[0080] The processor can determine the first target working parameter and the second target working parameter according to the difference between the current target voltage and the current output voltage. The first target working parameter is the working parameter of the boost circuit, and the second target working parameter is the working parameter of the buck circuit.

[0081] The boost circuit can operate according to the first target operating parameter, and the buck circuit can operate according to the second target operating parameter to adjust the voltage of the electrical pulse signal output by the output circuit.

[0082] It can be seen that the processor can adjust the increase and / or decrease of the output voltage by controlling the operating parameters of the boost circuit and the buck circuit, can achieve the increase and / or decrease of the envelope voltage, can prevent the envelope voltage from remaining unchanged, and can improve the accuracy of voltage control.

[0083] In some embodiments, the processor can determine the first target operating parameter corresponding to the absolute difference according to the first correspondence between the difference interval and the operating parameter. The processor can determine the second target operating parameter corresponding to the absolute difference according to the second correspondence between the difference interval and the operating parameter. The first correspondence is the correspondence for determining the operating parameter of the boost circuit, and the second correspondence is the correspondence for determining the operating parameter of the buck circuit. For a detailed description, reference can be made to the related description of determining the target operating parameter.

[0084] In some embodiments, the processor can determine the first target operating parameter corresponding to the absolute difference according to the third correspondence between the difference and the operating parameter. The processor can determine the second target operating parameter corresponding to the absolute difference according to the fourth correspondence between the difference and the operating parameter. The third correspondence is the correspondence for determining the operating parameter of the boost circuit, and the fourth correspondence is the correspondence for determining the operating parameter of the buck circuit. For a detailed description, reference can be made to the related description of determining the target operating parameter.

[0085] In some embodiments, the operating parameter can include the duty cycle.

[0086] The duty cycle is the duty cycle of Pulse Width Modulation (PWM). The duty cycle of PWM is the proportion of the pulse signal in one cycle.

[0087] With different duty cycles, the values of voltage rise and / or fall are different, and the speeds of voltage rise and / or fall are also different.

[0088] Exemplarily, the first correspondence between the difference interval and the duty cycle can be shown in Table 1:

[0089] Difference interval Duty cycle Remarks (4000,+∞] 60 Quick adjustment (1000,4000] 10 Medium-speed adjustment (0,1000] 0 Slow adjustment

[0090] Table 1

[0091] Exemplarily, the second correspondence between the difference interval and the duty cycle can be shown in Table 2:

[0092]

[0093]

[0094] Table 2

[0095] As shown in Table 1 and Table 2, different difference intervals correspond to different duty cycles, and different duty cycles result in different voltage adjustment speeds.

[0096] It should be understood that the above is an exemplary description of the first correspondence and the second correspondence, and is not intended to limit them. Exemplarily, 4000 can be replaced by 6000. Among them, the unit of the difference interval in Table 1 and Table 2 can be millivolts (mV).

[0097] The processor can enable the voltage adjustment circuit and also determine whether the modulation envelope is available. Only when it is determined that the modulation envelope is available can the voltage adjustment circuit be used to adjust the voltage.

[0098] Exemplarily, please refer to Figure 7 , Figure 7 which is a schematic diagram of an electrical pulse signal disclosed in an embodiment of the present application. Please refer to Figure 8 , Figure 8 which is a schematic diagram of another electrical pulse signal disclosed in an embodiment of the present application. Figure 7 is a schematic diagram of an electrical pulse signal without voltage control, Figure 8 is a schematic diagram of an electrical pulse signal with voltage control. It can be seen that after the voltage control of the present application, the glitches of the electrical pulse signal can be reduced and the voltage stability can be improved.

[0099] Please refer to Figure 9 , Figure 9 which is a schematic flowchart of a voltage adjustment method disclosed in an embodiment of the present application. Among them, the voltage adjustment method can be applied to the above-mentioned electrostimulation massage device. The electrostimulation massage device can include a memory, a processor, a feedback circuit, a voltage adjustment circuit, and an output circuit. The voltage adjustment method can include the following steps.

[0100] 901. Determine the electrostimulation parameters for defining the correspondingly periodically repeated modulation envelope according to the stored electrostimulation parameter data.

[0101] The memory stores electrostimulation parameter data. The electrostimulation massage device can determine the electrostimulation parameters for defining the correspondingly periodically repeated modulation envelope according to the electrostimulation parameter data stored in the memory.

[0102] Among them, the detailed descriptions of the electrostimulation parameter data, the memory, and the electrostimulation parameters can refer to the relevant descriptions above and will not be elaborated here.

[0103] 902. Determine the current target voltage according to the modulation envelope.

[0104] After the electro - stimulation massage device determines the electro - stimulation parameters, it can determine the current target voltage according to the corresponding modulation envelope.
