But the existing nursing instrument is the voltage type nursing instrument, and the voltage type nursing instrument can control the value of output voltage in the working process, and the output current is mainly determined by the external impedance, that is, the voltage type nursing instrument can reasonably control the voltage in the working process, but cannot accurately control the output current. And because the conductivity of the body, skin and the like of different users is different, therefore, when different users use, the external impedance formed by the human body is different, so when the voltage is reasonably controlled, because the impedance formed by the human body is different, the current generated is also different, that is, the current will suddenly increase, for example, when the user's skin is dry, the conductivity of the skin will be high, so under the condition that the voltage does not change, the current of the circuit will increase, so when the user uses the nursing instrument, the user will feel the needle prick and the tingling due to the sudden increase of the circuit.

[0093] Power management module (U5 and J1): TP4054 is a typical lithium battery charging management IC responsible for managing the charging state of the battery. It is connected to the battery (labeled BAT+ and BAT-) and adjusts the charging current through resistor R10.

[0094] The charging module also includes an indicator light LED to indicate the charging state of the battery.

[0095] Charging connector allows external power supply to charge the battery through the interface.

[0100] The circuit can be used for power management of the care instrument, providing functions such as battery charging, status indication, and USB output.

[0101] The care instrument control circuit further includes an amplification circuit as shown in Figure 7 , which can be used for signal processing or control. The amplification circuit specifically includes:

[0102] Transistors;

[0103] Multiple resistors, which can have resistance values of 100KΩ, 62KΩ, 18KΩ, etc. Resistors are used in circuits to limit current and determine voltage distribution.

[0104] Ports P1 and P2: used for input or output of signals.

[0105] Power supply voltage VC: used to power the entire circuit.

[0106] Coupling: multiple transistors are cascaded through resistors and capacitors, which can be used to amplify input signals.

[0107] Switches or control terminals T1 and T2: used to control the working state of the circuit.

[0108] The circuit is a multi-stage amplifier circuit that uses multiple transistors and resistor devices to amplify weak signals or as a control module.

[0109] The circuit of the boost circuit 6 is as shown in Figure 9 , which specifically includes:

[0110] Power supply (BAT+), which can be a battery or mains electricity.

[0111] Inductor (L1): L1 is a 1000 microhenry inductor, which is used to store electrical energy and provide electromagnetic induction when the current changes. It is one of the key components of the boost converter circuit, which can help to increase the output voltage.

[0113] PWM input (PWM): PWM (Pulse Width Modulation) signal input is marked as PWM. This signal controls the base of transistor Q1 through R12 resistor, so as to adjust the on-off time of current and control the efficiency of the boost circuit.

[0114] Diode: used to prevent current backflow. This diode allows the current in the inductor to release in the output direction when Q1 is off, and prevents the current from returning to the power supply side.

[0115] Capacitor (C5, C4): C5 and C4 are two capacitors of the same specification, marked as 1206 / 225 / 50V, indicating their package, capacity (2.25 microfarad) and voltage resistance value (50V). These capacitors are used for filtering and stabilizing the output voltage.

[0116] Output voltage (VC): it is used to provide the voltage converted by the boost to the load.

[0117] Working principle:

[0118] When the circuit works, the PWM signal controls the switching of transistor Q1. When Q1 is on, the inductor L1 stores energy; when Q1 is off, the energy in the inductor is released to the capacitors C5 and C4 through the diode, boosting the output voltage VC. In this way, by adjusting the duty cycle of the PWM signal, the size of the output voltage or current can be controlled.

[0119] The nursing instrument further comprises a state display lamp, which can be specifically a LED lamp in the circuit shown in Figure 8 The state of the LED lamp can be controlled through the circuit shown in Figure 8 , so as to display the working state of the nursing instrument. The circuit is composed of one LED (Light Emitting Diode), one resistor R14 and one diode D1. The function of the circuit is to convert the input signal into the output signal and display it through the LED.

[0121] Power supply, located on the left side of the circuit, which can be specifically a battery or a direct current power supply.

[0122] Resistor (R20 and R21): R20 is a 27kΩ resistor, and R21 is a 100kΩ resistor. They are connected together to form a voltage divider. The function of the voltage divider is to divide the input voltage according to the ratio of the two resistors, so that the voltage at the output end is a part of the input voltage.

[0123] Output: There are two outputs in the circuit, labeled BATAD and BAT+, respectively. BATAD is connected between two resistors and outputs the voltage after voltage division. BAT+ is connected after resistor R21 and outputs the positive voltage of the power supply.

[0124] Working principle: When voltage is input from the power supply, R20 and R21 form a voltage dividing circuit. According to the ratio of resistance values, the voltage at BATAD will be a part of the input voltage.

[0125] Specifically, the voltage at BATAD will be calculated by the following formula:

[0126]

[0127] Where Vin is the input voltage, and R20 and R21 are resistance values. Therefore, the voltage on BATAD will be lower than the voltage on BAT+.

[0128] This voltage dividing circuit is used to detect the battery voltage. BATAD can be connected to an analog-to-digital converter (ADC) for monitoring the battery voltage state, while BAT+ provides the actual voltage of the battery to other circuits for use.

[0132] Input signal (JR): such as from an external control signal or sensor. When JR inputs a high voltage, the gate of transistor Q9 is controlled through resistor R17.

[0133] Resistors (R17 and R18): R17 is a 1KΩ resistor that limits the current of input signal JR to prevent overloading of the transistor gate. R18 is a 10KΩ resistor that pulls the transistor gate to ground (ground), ensuring that the transistor Q9 is in the off state when there is no input signal.

[0134] Load (JR): connected to the output of the power supply, used to represent the load device. Q9 controls whether the power supply BAT+ is turned on to this load device.

[0135] The working principle of the circuit is: when the JR input is high level, the gate voltage of Q9 is raised through the resistance R17, Q9 is turned on, the current flows from BAT+ to the load device (the JR interface on the right side), thereby driving the load.When the JR input is low level, the gate voltage is pulled down by R18, Q9 is closed, the current cannot flow, and the load is powered off. Through the circuit, the opening and closing of the nursing instrument can be controlled.

[0136] The working principle of the circuit is: when the JR input is high level, the gate voltage of Q9 is raised through the resistance R17, Q9 is turned on, the current flows from BAT+ to the load device (the JR interface on the right side), thereby driving the load.When the JR input is low level, the gate voltage is pulled down by R18, Q9 is closed, the current cannot flow, and the load is powered off. Through the circuit, the opening and closing of the nursing instrument can be controlled. Figure 5 A specific current mode (current mode) pulse control circuit is introduced.

[0137] The circuit includes a voltage output circuit 510 and a constant current source circuit 520. Figure 5 The working process of the circuit in the application is as follows: the emitter of Q24 is connected to the negative electrode of diode D2 through resistance R75, the collector serves as a constant pulse current output to the electrode piece (i.e., the electrode strip 300), and the current output from the electrode piece (i.e., the electrode strip 300) is equal to the current on Q25, that is, Uc6 / (R74+R73), which does not change with the change of the human body impedance, but changes with the voltage on C6, that is, changes with the duty ratio of PWM, so that different sizes of constant current pulse outputs can be realized by using a single-chip microcomputer, and the current pulse does not change with the change of the human body impedance.

[0138] According to the working process, the utility model discloses an independent component, that is, a triode, a diode, a resistance, a capacitor and an inductor, which are used to form a constant pulse current circuit, and the circuit is composed of two parts, that is, a boost circuit composed of a capacitor C24, a diode D1, a resistance R29, a triode Q17, an inductor L1, a capacitor C5, a diode D2, a capacitor C6 and a capacitor C7, and the capacitor C24 serves as a direct current isolation function; the single-chip microcomputer uses a PWM pulse to control the switching of the triode Q17, and the duty ratio of the PWM determines the size of the voltage after rising; the triode Q24, the triode Q25, the resistance R75, the resistance R74 and the resistance R73 form a mirror constant current source circuit, the voltage type output is converted into a current type output, the output is modulated into pulses of different widths and intervals by the single-chip microcomputer, the massage effect is realized, the circuit can effectively adapt to different human body surface impedances, the cost is low, and the circuit has wide adaptability.

[0139] In order to further feedback adjust the output circuit on the electrode piece (i.e., the electrode strip 300), a sampling resistance and Q25 can be connected in series, then the width and interval of the output pulse of the pulse control circuit are adjusted by collecting the current on the sampling resistance, so that the output current and the required current can be more consistent.
