Detailed Description

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Referring to fig. 1, the present invention provides a preferred embodiment of a method for adjusting the gear positions of an electrical stimulation massage device.

The electric stimulation massage device comprises an impedance detection module and an electrode assembly used for outputting electric pulse signals, wherein when the electrode assembly is attached to the skin of a human body and outputs the electric pulse signals to the human body, the impedance detection module acquires the impedance value of the human body. The electrode assembly comprises electrodes which are arranged in pairs, the electrode pieces are attached to the skin of a human body, and the human body impedance value is an impedance value between the electrodes which are arranged in pairs when the electrode pieces are attached to the skin of the human body for electrical stimulation massage.

The human body impedance value is influenced by various factors such as the joint degree of the electrode assembly and the human body skin, the dryness degree of the human body skin, the wearing time of the electric stimulation massage device and the like, and is in a constantly changing state, so that the applicable massage gears of the electric stimulation massage device can be different when the electric stimulation massage device is worn every time.

In order to improve user experience, the electric stimulation massage device can automatically enter a gear intelligent adjusting mode when the device is started. In the mode, the massage gears can be adaptively adjusted to the optimal gears matched with the current impedance value of the user, and the frequent operation of adjusting the gears when the user wears the massage device can be reduced.

The gear adjusting method of the electric stimulation massage device comprises the following steps:

Specifically, voltage gears adapted to the human body at different impedance values are preset in the electric stimulation massage device, and the electrode assembly outputs different electric pulse signals corresponding to the voltage gears under different voltage gears.

After the electric stimulation massage device is started and enters a gear intelligent adjustment mode, the impedance detection module detects a human body impedance value, the electric stimulation massage device adjusts a voltage gear, a target gear corresponding to the current human body impedance value serves as a current voltage gear, and the electrode assembly outputs an electric pulse signal corresponding to the current voltage gear, namely the target gear.

The detection of the body impedance value by the impedance detection module may be real-time or periodic,

the real-time detection can achieve the purpose that the gears change in real time along with the change of the human body impedance value, and the adjustment accuracy is high; the periodic detection can slow down the speed of the gear changing along with the change of the human body impedance value, and can meet different use habits of users.

In an embodiment, the preset trigger adjustment may be a power-on signal, that is, when the power-on signal is detected/received, the intelligent gear adjustment mode is entered.

It should be noted that the above method is also applicable to a scenario when the massage mode is switched, and the preset trigger adjustment may be a massage mode switching signal, that is, when the massage mode switching signal is detected/received, the intelligent gear adjustment mode is entered. Therefore, when the massage mode is switched, the massage gear can be adaptively adjusted to the gear matched with the current impedance value of the user according to the impedance value of the human body, so that the operation of frequently adjusting the gear when the user wears the massage device can be reduced, and the pricking pain can be avoided.

Particularly, the method is suitable for the user to switch the massage mode when the electric stimulation massage device does not enter the steady massage state within the preset time after the power-on and the massage device is switched over.

In a preferred embodiment, some users prefer manual adjustment, for example, given that intelligent adjustment may sometimes fail to meet user requirements. Therefore, before entering the gear intelligent adjustment mode, it is necessary to determine whether the user performs an operation of manually adjusting the gear, please refer to fig. 1, and the specific determination method is as follows:

after receiving the trigger signal, waiting for a first preset time;

if the manual gear adjusting signal is not detected within the first preset time, entering a gear intelligent adjusting mode;

and if the manual gear adjusting signal is detected within the first preset time, entering a manual adjusting mode.

Namely, a certain waiting time, namely a first preset time, is preset in the electrical stimulation massage device, and within the waiting time, if a user manually adjusts a massage gear, the manual adjustment mode is entered, otherwise, the intelligent gear adjustment mode is entered.

In the manual adjustment mode, the voltage gear can be adjusted to the corresponding manual gear according to the current manual adjustment gear signal, and the electrode assembly is controlled to output an electric pulse signal corresponding to the manual gear. For example, if the gear is manually selected to be 2V, an electric pulse signal with 2V amplitude is output, and if the gear is manually switched to be 5V to increase the force, an electric pulse signal with 5V amplitude is output.

Specifically, the trigger signal may be a power-on signal, that is, when a preset trigger condition is met, the step of entering the gear intelligent adjustment mode includes: after receiving a starting signal, waiting for a first preset time; if the manual gear adjusting signal is not detected within the first preset time, entering a gear intelligent adjusting mode; and if the manual gear adjusting signal is detected within the first preset time, entering a manual adjusting mode.

The trigger signal can also be a massage mode switching signal, that is, when a preset trigger condition is met, the step of entering the gear intelligent regulation mode comprises the following steps: after receiving the massage mode switching, waiting for a first preset time; if the manual gear adjusting signal is not detected within the first preset time, taking a default gear as a gear intelligent adjusting mode to determine a gear to enter a target massage mode; and if the manual gear adjusting signal is detected within the first preset time, the gear determined by taking the default gear as the manual adjusting mode enters the target massage mode.

Therefore, after the power-on or the mode switching, the gear adjusting mode can be determined according to the preference of a user.

In one embodiment, if the electric stimulation massage device is started, a user does not manually adjust gears at the first time, the electric stimulation massage device enters a gear intelligent adjustment mode and receives a signal for manual gear adjustment of the user, the electric stimulation massage device enters the manual adjustment mode, the voltage gear is adjusted to a corresponding manual gear according to the current manual gear adjustment signal, and the electrode assembly is controlled to output an electric pulse signal corresponding to the manual gear. That is, the manual adjustment mode always has a higher priority level than the intelligent gear adjustment mode, so as to meet the requirement of the user for manual adjustment at any time.

In a preferred embodiment, in order to provide a sufficiently safe experience for a user, in the gear intelligent adjustment mode, the step of adjusting the voltage gear to the corresponding target gear according to the current human impedance value, and controlling the electrode assembly to output an electric pulse signal corresponding to the target gear is as follows:

Specifically, for the sake of safety, after entering the gear intelligent adjustment mode, the voltage gear is not directly adapted to the current human impedance value, but the voltage gear is adjusted to the initial safe gear first, which generally corresponds to a relatively weak voltage value. Along with the adjustment of the wearing condition of the human body and the increase of the wearing time, the human body impedance value is gradually reduced, the voltage level is gradually increased, and the electric pulse output of the electrode assembly is formally controlled in a mode that the voltage level is adaptive to the current human body impedance value until the human body impedance value reaches the conventional standard. The method provides guarantee for the safe use of the user, particularly the safe use at the initial starting.

In a preferred embodiment, besides the suitable massage gear needs to be found in a more convenient way when the machine is started, after different massage modes are switched during wearing, the suitable massage gear in the mode also needs to be found more conveniently. Therefore, when the electric stimulation massage device receives the massage mode switching signal, the electric stimulation massage device can also enter the intelligent gear adjustment mode. For a specific gear adjustment method during the switching of the massage mode, several different embodiments are listed below, please refer to fig. 2.

In one embodiment, the method for adjusting the gear position of the electrical stimulation massage device further comprises the following steps after the control electrode assembly outputs the electric pulse signal corresponding to the manual gear position or after the step of controlling the electrode assembly to output the electric pulse signal corresponding to the target gear position: and when the massage mode switching signal is detected, the voltage gear is restored to the default safe gear and then the target massage mode is entered.

Specifically, whether the electrical stimulation massage device is in the manual adjustment mode or in the gear intelligent adjustment mode, whether the user performs the operation of switching the massage mode or not is detected. In order to ensure the safety of a user at the first time after the massage mode is switched, a default safety gear is preset in the electrical stimulation massage device, when a massage mode switching signal is detected, the voltage gear is restored to the default safety gear, then the target massage mode is entered, and namely the default gear is used as the default safety gear to enter the target massage mode.

Before the massage mode is switched, the massage mode is in any mode of manual adjustment or gear intelligent adjustment, and after a massage mode switching signal is detected and a voltage gear is restored to a default safe gear, the massage mode enters a gear intelligent adjustment mode. This is because the voltage value of the default safety gear is very low, and after the voltage value is applied to a human body, the human body senses the voltage very weakly, so that the gear generally cannot meet the massage requirement of the user. The default safety gear may be one of a primary gear, a zero voltage gear, a safety voltage gear, or a user-defined gear.

Before the massage mode is switched, the massage module is in a manual adjustment mode, if the massage mode switching signal is not detected, a preset time is waited, and if the manual adjustment gear signal is not detected within the preset time, the electrode assembly is controlled to output an electric pulse signal corresponding to the current manual gear; and if the manual gear adjusting signal is detected within the preset time, controlling the electrode assembly to output an electric pulse signal corresponding to the adjusted manual gear.

Before the massage mode is switched, the massage mode is in a gear intelligent adjustment mode, if a massage mode switching signal is not detected, a preset time is waited, and if a manual gear adjustment signal is not detected within the preset time, an electrode assembly is controlled to output an electric pulse signal corresponding to a current target gear; and if the manual gear adjusting signal is detected within the preset time, controlling the electrode assembly to output an electric pulse signal corresponding to the adjusted manual gear.

Namely, if the user does not switch the mode, the gear is adjusted according to the original mode, and after the user manually adjusts the gear again, the electrode assembly is controlled to output the corresponding electric pulse signal according to the manually adjusted gear.

In one embodiment, the method for adjusting the gear position of the electrical stimulation massage device further comprises the following steps after the control electrode assembly outputs the electric pulse signal corresponding to the manual gear position or after the step of controlling the electrode assembly to output the electric pulse signal corresponding to the target gear position: waiting for a second preset time when the massage mode switching signal is detected, and entering a target massage mode in a gear intelligent adjustment mode if the manual gear adjustment signal is not detected within the second preset time; and/or if the manual gear adjusting signal is detected within the second preset time, entering a target massage mode by using a gear corresponding to the manual gear adjusting signal.

Specifically, whether the electrical stimulation massage device is in a manual adjustment mode or in a gear intelligent adjustment mode, whether the user performs the operation of switching the massage mode or not is detected. A certain waiting time, namely a second preset time, is preset in the electric stimulation massage device, and when a massage mode switching signal is detected, within the waiting time, if a user manually adjusts a massage gear, the user enters a target massage mode by taking a default gear as a gear determined by the manual adjustment signal; otherwise, the gear determined by the intelligent gear adjustment mode with the default gear as the gear enters a target massage mode.

The case where the user does not perform the massage mode switching is the same as the first embodiment enumerated above.

In one embodiment, the method for adjusting the gear position of the electrical stimulation massage device further comprises the following steps after the control electrode assembly outputs the electric pulse signal corresponding to the manual gear position or after the step of controlling the electrode assembly to output the electric pulse signal corresponding to the target gear position: when the massage mode switching signal is detected, the voltage gear is restored to the default safe gear and then enters the target massage mode, and within a third preset time after the massage mode enters the target massage mode, if the manual gear adjusting signal is detected, the gear is adjusted to the gear corresponding to the manual gear adjusting signal, and if the manual gear adjusting signal is not detected, the intelligent gear adjusting mode is entered.

The default safety gear may be one of a primary gear, a zero voltage gear, a safe voltage gear, or a user-defined gear.

Therefore, after the electric stimulation massage device enters a target massage mode through a default safety gear, whether the electric stimulation massage device enters a gear intelligent adjustment mode is judged, and self-adaptive adjustment of massage gears is achieved.

The same as the first embodiment as listed above is applied to the case where the user does not perform the massage mode switching.

In a preferred embodiment, when the electrical stimulation massage device is worn for a certain period of time, the electrode assembly is stably attached to the human body, and the human body impedance value tends to be stable under the condition that the human body skin state is stable. At this time, the electric stimulation massage device enters a steady state massage state, and the amplitude of the electric pulse signal output by the electrode assembly is weak according to the change of the impedance value of the human body.

Referring to fig. 2, P1 and P2 show the situation before and after entering the steady massage state, respectively. In the preferred embodiment, after the step of entering the gear shift intelligent adjustment mode when the preset trigger condition is met, typically after the electrical stimulation massage device is powered on and operated for a period of time, that is, after the control electrode assembly outputs the electrical pulse signal corresponding to the manual gear shift, or after the step of controlling the electrode assembly to output the electrical pulse signal corresponding to the target gear shift, the gear shift adjustment method further includes:

if the electric stimulation massage device enters a steady state massage state, acquiring the difference between a target massage mode and a current massage mode, acquiring a switching entering gear according to the difference and the current gear of the current massage mode, and taking the switching entering gear as a default gear to enter the target massage mode;

if the electric stimulation massage device does not enter the steady state massage state, the electric stimulation massage device can enter the target massage mode according to the mode in the gear adjusting method, for example, the electric stimulation massage device enters the target massage mode after the voltage gear is restored to the default safe gear, enters the target massage mode in the gear intelligent adjusting mode, or enters the target massage mode in the gear corresponding to the manual adjusting gear signal.

Specifically, when the user switches the massage mode, it is first determined whether the electric stimulation massage device enters a steady massage state. The basis for judging whether the electric stimulation massage device enters the steady state massage state is as follows: judging whether the wearing time of the user exceeds the preset time, judging whether the current human body impedance meets the preset stable condition, and considering that the electric stimulation massage device enters a steady state massage state when any one of the conditions is met or met. The preset stable condition may be that the current human body impedance value reaches a certain preset interval, or the difference between the human body impedance and the reference resistance is obtained continuously for multiple times and is smaller than a preset stable threshold value.

Through the above judgment, if the electrical stimulation massage device enters the steady state massage state, the current gear of the current massage mode is maintained, for example, the current massage mode is a relaxing mode, and the gear is 3V, the gear of the 3V is maintained to be switched to a new massage mode.

Or, through the above judgment, if the electrical stimulation massage device enters the steady massage state, the difference between the target massage mode and the current massage mode needs to be obtained first.

Under different massage modes, the waveforms of the electric pulses output by the electrode assembly are different, which are specifically represented by the pulse frequency and the pulse amplitude of the waveforms, and the difference can be a parameter obtained by integrating the difference between the pulse frequencies of the front waveform and the pulse frequencies of the rear waveform and the pulse amplitude of the front waveform and the pulse amplitude of the rear waveform, or a parameter obtained respectively according to the difference between the pulse frequencies of the front waveform and the pulse frequencies of the rear waveform or the pulse amplitude of the front waveform and the pulse amplitude of the rear waveform; alternatively, the difference may be determined based on the similarity between the preceding and following waveforms.

After the difference between the target massage mode and the current massage mode is obtained, the difference value is integrated on the basis of the value of the current gear of the current massage mode, for example, the difference value is added/multiplied on the basis of the value of the current gear, the gear switched into the target massage mode, namely the gear switched into the target massage mode is obtained, and then the gear switched into the target massage mode is used as a default gear to enter the target massage mode.

If the electric stimulation massage device does not enter the steady state massage state through the judgment, the target massage mode can be entered according to the mode in the gear adjusting method. The electric stimulation massage device does not enter a steady state massage state, which indicates that the impedance value of the human body still changes greatly at the moment, usually because the wearing condition changes to a less than optimal state, or the wearing time is not enough to adapt the human body to the current action, so that the impedance value still changes adaptively.

The following description is continued with the step intelligent adjustment mode entering the target massage mode, and at this time, if the step intelligent adjustment mode is adopted, the voltage step can be more quickly matched with the current human body impedance value.

Further, a certain time, that is, a fourth preset time, may be preset in the electrical stimulation massage device, and if the electrical stimulation massage device does not enter the steady state massage state, the step of entering the gear intelligent adjustment mode includes: and judging whether the user manually adjusts the gear within the fourth preset time after receiving the massage mode switching signal, and if the manual gear adjusting signal is not detected, entering an intelligent gear adjusting mode.

Correspondingly, the massage mode switching comprises the following specific steps:
