It may be provided that if the selection button SW2 is pressed once and the selection button SW2 is not pressed again for a second time since the selection button SW2 is pressed for the first time, the wearable device outputs a first pulse signal, reaches a first setting current after a first setting time and remains stable to a setting time point, and then descends to a state in which the wearable device is dormant. If the selection button SW2 is continuously pressed twice and the selection button SW2 is not pressed again within a second time from the first pressing of the selection button SW2, the wearable device outputs a second pulse signal, reaches a second set current after a second set time and remains stable to a set time point, and then descends to a state that the wearable device is dormant. If the selection button SW2 is continuously pressed three times and the selection button SW2 is not pressed again in the second time from the first pressing of the selection button SW2, the wearable device outputs a third pulse signal, reaches a third setting current after a third setting time and keeps stable to a setting time point, and then descends to the state that the wearable device is in sleep.
For example, the initial power mode of the wearable device may be set to be a power increasing mode, the selection button SW2 is clicked to make the wearable device enter a power limiting mode, the power limiting mode refers to that the power remains unchanged in the mode, the selection button SW2 is clicked again to make the wearable device enter a power decreasing mode, the selection button SW2 is clicked again to make the wearable device enter the power limiting mode, or the selection button SW2 is clicked again to make the wearable device enter the power increasing mode. Illustratively, the second and third gears are in the first 14min (first gear is in the first 12 min), the intensity of the electrical stimulation is gradually increased, and when the intensity of the electrical stimulation is larger, the intensity of the electrical stimulation can be stopped to be increased by pressing the selection button SW2 once, and the intensity of the electrical stimulation is kept at the same level until the power limitation is realized. If the citrus electrostimulation intensity is still too high after the holding power is performed, the select button SW2 may be pressed again, at which point the power (current) is gradually reduced and maintained at a certain level until stopped. If power is to be increased after the hold power is performed, the select button SW2 may be quickly double-clicked, at which time the power (current) is gradually increased and maintained at a certain level until it is stopped. When power reduction or enhancement is performed, power (current) limitation, i.e., stopping power increase or decrease, can be achieved by simply pressing the selection button SW2 in sequence. The wearable device enters a sleep state when the load current of the wearable device suddenly drops, or enters a sleep state when the operating voltage of the wearable device suddenly rises. Pressing the switch button SW1 again puts the wearable device in a sleep state.
For example, the working time of the wearable device in each gear may be set to be 18-20min, the first time and the second time are 8-12s, the first set time is 10-15min, the second set time and the third set time are 12-16min, the first set current is 13-15mA, and the second set current and the third set current are 15-16mA. The first pulse signal may be a square wave of 450-550us pulse width and 100-120HZ, the second pulse signal may be a square wave of 580-620us pulse width and 50-70HZ, and the third pulse signal may be a square wave of 450-550us pulse width and 90-100 HZ. The set time point is the last two minutes of the working time of each gear, namely the wearable device can be kept stable to the last 2 minutes when the first gear reaches the first set current when the first gear works to the end of 18 minutes.

Illustratively, the buzzer 81 "beep" may be set to sound when the select button SW2 is pressed once, indicating successful selection of first gear; when the button SW2 is continuously pressed twice, the buzzer 81 sounds a beep to indicate that the second gear is successfully selected; when the three times of selection button SW2 is continuously pressed, the buzzer 81 sounds three times of a beep, which indicates that three gears are successfully selected, and the prompting function for a user is achieved.
