[0002] The brain care device uses electrodes to stimulate the left dorsolateral prefrontal lobe, right dorsolateral prefrontal lobe, and the center of the forehead. Transcranial electrical stimulation is mainly used to adjust the resting membrane potential of the brain and the balance of excitation and inhibition between the left and right brains, thereby improving mood, concentration, sleep, and memory. The existing brain care device has a single stimulation mode and a low efficiency in the control mode. It requires self-adjustment of parameters, and it is impossible for people to easily change the mode and parameters of the brain care device electrode stimulation. As a result, the effect of using the brain care device is poor and very inconvenient, and people have conducted a lot of research on this. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a three-electrode brain care device and a control method thereof, which can solve the above-mentioned problems in the prior art.

[0004] The present invention is achieved through the following technical solutions: A three-electrode brain care device and a control method thereof of the present invention include a main body, a plurality of electrodes are arranged on one side of the main body, and the electrode includes a first electrode cover, a second electrode cover and a third electrode cover, a circuit board is arranged in the main body, a control module is arranged on the circuit board, and the control module is electrically connected to the electrodes. The control module realizes the functions of DC forward stimulation, DC reverse stimulation and AC stimulation by arranging cathodes or anodes in the first electrode cover, the second electrode cover and the third electrode cover, and the control module can control the stimulation frequency, current size and stimulation time of the electrode according to different stimulation modes.

[0005] A further technical solution is that in the positive stimulation mode of the direct current mode, the first electrode cover represents the anode, the second electrode cover represents the cathode, the anode is placed on the left dorsolateral prefrontal lobe, and the cathode is placed on the right dorsolateral prefrontal lobe.

[0006] A further technical solution is that in the reverse stimulation mode of the direct current mode, the second electrode cover represents the anode, the first electrode cover represents the cathode, the anode is placed on the right dorsolateral prefrontal lobe, and the cathode is placed on the left dorsolateral prefrontal lobe.

[0007] According to a further technical solution, in an alternating current mode, the second electrode cover and the first electrode cover switch between the anode and the cathode, so that the anode and the cathode are periodically changed in the left and right dorsolateral prefrontal lobes.

[0008] A further technical solution is that in the forward stimulation mode of the DC mode, the second electrode cover or the first electrode cover is set as a cathode, and the third electrode cover is set as an anode, the anode is placed in the middle of the forehead, and the cathode is placed in the right dorsolateral prefrontal lobe or the left dorsolateral prefrontal lobe.

[0009] A further technical solution is that in the AC mode, the third electrode cover switches between the cathode and the anode, and the second electrode cover correspondingly switches between the anode and the cathode, and the anode and the cathode are periodically changed in the middle of the forehead and the right dorsolateral prefrontal lobe.

[0010] A further technical solution is that the control module includes a Bluetooth module, a central processing unit, a digital-to-analog module, a current conversion module, a polarity switching module and an analog-to-digital module. The APP end of the external space establishes a signal connection with the Bluetooth module, the Bluetooth module is electrically connected to the central processing unit module, the central processing unit module is electrically connected to the digital-to-analog module, the digital-to-analog module is electrically connected to the current conversion module, the current conversion module is electrically connected to the polarity switching module, the polarity switching module is electrically connected to the electrode, and the electrode and the analog-to-digital module are electrically connected to the central processing unit.

[0011] A control method for a three-electrode brain care device: in the first step, the Bluetooth module transmits the instructions of the APP end to the central processing unit; in the second step, the central processing unit performs logic control and signal processing; the digital-to-analog module converts the digital signal of the central processing unit into a specified voltage; in the third step, the current conversion module converts the voltage generated by the digital-to-analog module into a corresponding stimulation current through V and I; in the fourth step, the analog-to-digital module converts the stimulation current into a voltage through I and V circuits, and transmits the signal to the central processing unit, and the central processing unit dynamically changes the current data of the circuit to meet the set data.

[0012] A further technical solution is a polarity switching module, which switches the polarity of the two electrodes according to the high and low levels sent by the central processor:

[0013]

[0014] When the app side sets the forward mode, the instruction is transmitted to the Bluetooth module, and the central processor sets IO1=1 and IO2=0 after receiving the instruction; when the app side sets the reverse mode, the instruction is transmitted to the Bluetooth module, and the central processor sets IO1=0 and IO2=1 after receiving the instruction; when the app side sets the AC module, the instruction is transmitted to the Bluetooth module, and the central processor sets IO1=1 and IO2=1 after receiving the instruction.

In the second step, after receiving the instruction, the central processor sends it to the digital - to - analog module. The digital - to - analog module converts the digital signal into the corresponding voltage and then transmits it to the current conversion module. In the third step, it is delivered to the electrode through the polarity switching module. In the fourth step, a resistor is connected in series in the whole loop to collect the current. The current data is transmitted to the central processor through the analog - to - digital module. The central processor calculates to obtain the current value as Iin. When Iin < Iout, the output current value will be increased until Iin = Iout. When Iin > Iout, the output current value will be decreased until Iin = Iout.

[0016] The beneficial effects of the present invention are as follows: First, by setting the second electrode cover, the first electrode cover, and the third electrode cover, under the polarity conversion of the second electrode cover, the first electrode cover, and the third electrode cover, the functions of DC forward stimulation, DC reverse stimulation, and AC stimulation can be realized, and the left dorsolateral prefrontal cortex, right dorsolateral prefrontal cortex, and the middle of the prefrontal cortex of the brain can be excited or inhibited, and the effect is good.

[0017] Second, through the specific modular setting of the control module, the current magnitude, stimulation time, and frequency of the electrode can be controlled according to different stimulation modes to execute the corresponding mode functions, and the control effect is good. And the current information can be real - time feedback through the analog - to - digital module to facilitate the central processor for real - time compensation, so that the electrode can work stably according to the current magnitude of the specified mode. The setting of the polarity switching module also enables the first electrode cover, the second electrode cover, and the third electrode cover to be set as the cathode or anode, and then perform DC forward, DC reverse, and AC operations. The structure is simple and the control is efficient. BRIEF DESCRIPTION OF THE DRAWINGS
