pins

3 and 4 of a switching power supply U enters a booster circuit, after the booster circuit works when power is supplied, a single chip microcomputer module U1 does not output a control signal at the beginning, the anode of the 5V power supply (an electrolytic capacitor EC1 and a nonpolar capacitor C9 are input power supply filtering) is unidirectionally conducted through an inductor L1 and a Schottky diode D5 and is reduced to 4.3V, a voltage divider is formed by a resistor R7, a resistor R2 and an adjustable resistor RV, voltage is generated to act on the pin 3 of the booster integrated circuit U2, the booster integrated circuit U2 is started to work, the

pins

5 and 6 of the booster integrated circuit U2 generate stable voltage under the action of the internal circuit thereof, and the stable voltage output is kept after the diode D5. The output voltage UX is 1.28 (1+ R7/(RV + R2)) (the voltage value is 5.2-50V), and the voltage can be regulated by regulating different resistance values of the adjustable resistor RV, so that the highest output voltage reaches the requirement; then, the power outputted from the diode D5 enters one end of the resistor R29 of the power polarity converting circuit, and the power polarity converting circuit is powered on. After the power polarity conversion circuit is powered on, a high level is generated at pin 9 of the mcu U1 and enters a gate of a fet Q12 (all fets are MOS transistors) through a resistor R32, the MOS transistor Q12 is turned on, the power UX output from the boost circuit is grounded through a resistor R30 and a resistor R40 to form a loop, and a divided voltage UX is generated at the gate of a MOS transistor Q8 (R30/(R30+ R40)), so that the MOS transistor Q8 is turned on (at this time,

pins

6 and 8 of the mcu U1 are low, and gates of the MOS transistors Q7, Q9, Q10, and Q11 are not input with signals and are in an off state). Because the drain of the MOS transistor Q8 is connected to one of the aluminum foils LB1 and LB2, the source and drain voltages of the MOS transistor Q8 are UX, when no load is added between the two aluminum foils LB1 and LB2, the NPN triode Q2 is in an off state, at this time, the pin 10 of the single chip microcomputer module U1 is at a high level, and when a load is added between the two aluminum foils LD1 and LD2 (that is, the hand or foot of a person is placed on the two towels in a wet state), because the aluminum foil LB2 is connected to the base of the NPN triode Q2 through the resistor R9, the base voltage of the NPN triode Q2 is higher than 0.7V, and then the NPN triode Q2 is turned on; at this time, the collector and the emitter of the NPN triode Q2 are grounded to zero at the same time (the resistors R9 and R8 are peripheral elements of the NPN triode Q2), then the pin 10 of the single chip microcomputer module U1 is also grounded and pulled down to a low level, and thus, by detecting the level value of the pin 10 of the single chip microcomputer module U1, the single chip microcomputer module U1 can determine whether the two aluminum foils LB1 and LB2 are connected to the load.

As shown in fig. 1, 2, 3, 4, and 5, the single chip microcomputer module U1 and the power supply polarity conversion circuit: after the single chip microcomputer module U1 is powered on to work, under the action of an internal circuit thereof, when the single chip microcomputer module U1 judges that two aluminum foil sheets LB1 and LB2 are connected to a load, three control power output ends 6, 8 and 9 thereof output high levels at certain time intervals (in the embodiment, every 4 minutes is set), step down and current limit are carried out through resistors R41 and R31, R37 and R32, and the high levels enter a gate of a MOS transistor Q11, a gate of a MOS transistor Q9, a gate of a MOS transistor Q10 and a gate of a MOS transistor Q12; when the high level output by the pin 6 of the single chip microcomputer module U1 enters the grid electrode of the MOS tube Q11 through the resistor voltage reduction current limiting R41, the MOS tube Q11 is conducted, the drain electrode outputs the low level and enters the aluminum foil LB2, meanwhile, the high level output by the pin 9 of the single chip microcomputer module U1 enters the grid electrode of the MOS tube Q12 through the resistor R32 voltage reduction current limiting, and the MOS tube Q12 is conducted; the voltage UV output by the drain of the MOS transistor Q12 is grounded through the resistor R30 and the resistor R40 to form a loop, and a divided voltage UV (R30/(R30+ R40)) is generated at the gate of the MOS transistor Q8, so that the MOS transistor Q8 turns on the drain thereof to output the divided voltage UV to enter the aluminum foil LB 1; thus, after the power polarity conversion circuit outputs power, the UV voltage is input into the aluminum foil LB1, and the low level is input into the aluminum foil LB 2; at this moment, since no input voltage signal is in a cut-off state at the gates of the MOS transistor Q9 and the MOS transistor Q10, the MOS transistor Q7 is also in a cut-off state. When the 8-pin output high level of the single chip microcomputer module U1 is subjected to voltage reduction and current limitation through the resistor R37 and enters the gate of the MOS tube Q10, the MOS tube Q10 conducts the drain output low level thereof and enters the aluminum foil LB1, meanwhile, the high level is subjected to voltage reduction and current limitation through the resistor R31 and enters the gate of the MOS tube Q9, the MOS tube Q9 conducts the drain output low level voltage UV through the resistor R29 and the resistor R39 and is grounded to form a loop, a divided voltage UV is generated at the gate of the MOS tube Q7 (R29/(R29+ R39)), further, the MOS tube Q7 conducts the drain output divided voltage UV thereof and enters the aluminum foil LB1, so that after the power polarity switching circuit outputs the power, the UV voltage is input to the aluminum foil 2, and the low level is input to the LB1, and at this moment, no input voltage signal is in a cut-off state between the gates of the MOS tube Q12 and the; the MOS transistor Q8 is also in the off state. Through the circuit function, under the action of the internal circuit of the singlechip control module U1, the power polarity conversion circuit converts the polarity of the power input to the aluminum foil LB1 and LB2 at intervals of a certain time (4 minutes). Does not need manual conversion of a user, brings convenience to the user and improves the treatment effect.

As shown in fig. 1, 2, 3, 4 and 5, before the novel physiotherapy device is used and before a human body carries out foot or hand physiotherapy, the aluminum foils LB1 and LB2 are positioned at two sides of the plastic tray 2, water is poured into the plastic tray 2, a partition is arranged in the middle of the plastic tray 2 to partition the areas where the two aluminum foils LB11 and LB2 are positioned, it is ensured that the two parts of the plastic tray 2 cannot be communicated after being added with water, and two towels are respectively placed on the two aluminum foils LB1 and LB 2; in the treatment, feet or hands are separated from the middle of the plastic plate 2 and placed on the two towels, the two towels are respectively contacted with the two pieces of aluminum foil LB11 and LB2, conductive water is arranged in the two plastic plates 2, the towels and the plastic plates 2 are submerged by the water, the feet or the hands are indirectly contacted with the foils LB11 and LB2, the feet or the hands are equivalent to a resistor (the resistance value is about 1K-20K omega, the human body is different), the feet or the hands are equivalent to a person, the feet or the hands are respectively connected with the source electrodes of the two MOS tubes Q7 and Q8 through the water, the towels and the two foils LB1 and LB2, and a load is connected between the two foils LB1 and LB2 to a certain degree. Because the sources of the MOS transistors Q10 and Q11 of the power polarity conversion circuit are connected with the resistor RS and are simultaneously connected with the 11 pin of the single chip microcomputer module U1 through the resistor R1, in this way, the single chip microcomputer module U1 can obtain that the current value flowing through the resistor RS IS equal to V11/RS by detecting the level value V11 of the 11 pin (under the action of the internal circuit of the single chip microcomputer U1, the current signal IS displayed through the digital display tube D3), the present invention IS set that when the current value flowing through the resistor RS IS less than 1 milliampere (here, in order to prevent misoperation and prevent excessive water adding, two foils LB1 and LB2 are directly connected through water), the default IS that no load IS connected before two foils LB11 and LB2, at this time, the single chip microcomputer module U1 under the action of the internal circuit, three control

power output terminals

6 and 8 pin output low level, 9 pin outputs high level, in this way, the MOS transistor Q9, the MOS transistor Q7, Q10, and Q11 are in cut-off state, the MOS tube Q12 and the MOS tube Q8 are sequentially switched on, at the moment, the current between the two foils LB1 and LB2 is switched off, and the three control power output ends 6, 8 and 9 do not output high level; when the single chip microcomputer module U1 detects that 10 pins are high level and the current value flowing through the resistor RS is more than 1 milliampere, the load is connected between the two foils LB1 and LB2 at the moment, and the three control power output ends 6, 8 and 9 pins output high level; otherwise, the load is not connected, and the three control power output ends 6, 8 and 9 do not output high level.

As shown in fig. 1, 2, 3, 4, and 5, in the voltage boost circuit, a resistor R54 is connected in parallel with resistors R2 and R55, one end of each of the resistors R54 and R55 is connected to the drain of a MOS transistor Q21 and Q22, the sources of the MOS transistors Q21 and Q22 are grounded, gates of the MOS transistors Q21 and Q22 are connected to the 5 pin and the 12 pin of a single chip microcomputer module U1, respectively, when the single chip microcomputer module U1 determines that a load is connected between two foils LB1 and LB2 under the action of its internal circuit, the three control

power output terminals

6, 8, and 9 output high levels, and the 5 pin and the 12 pin of the single chip microcomputer control circuit U1 both output high levels to enter the gates of the MOS transistors Q21 and Q22, respectively, so that the MOS transistors Q21 and Q22 are turned on; at this time, the resistors R2, R54 and R55 are connected in parallel, and the output voltage of the 5 th pin and the 6 th pin of the boost circuit is about UX/3 after passing through the diode D5. When the 5 pin outputs high level and the 12 pin outputs low level under the action of the internal circuit of the singlechip module U1, the MOS tube Q22 is turned on, the MOS tube Q21 is turned off, and because the resistors R2 and R55 are connected in parallel, the voltage output by the 5 pin and the 6 pin of the booster circuit through the diode D5 is about UX/2. When the pin 5 of the single chip module U1 outputs low level and the pin 12 outputs low level, the MOS transistor Q22 is turned on and the MOS transistor Q21 is turned off, and at this time, the pin 5 and the pin 6 of the boost circuit output voltage through the diode D5 is about UX. In the single chip microcomputer module U1, a pin 14 of the single chip microcomputer module U1 is connected with one end of a resistor R12 and is simultaneously connected with one end of an adjustable resistor RV2, the other end of the resistor R12 is connected with a voltage VCC, and the other end of the adjustable resistor RV2 is grounded, so that the single chip microcomputer module U1 obtains a current duty ratio DT which needs to be added between two foils LB1 and LB2 by detecting the voltage value of the pin 14 of the single chip microcomputer module U1; the single chip microcomputer module U1 outputs a PWM signal of 10KHZ at the 6 pin under the action of its own circuit, the PWM signal of the 6 pin slowly increases or decreases the duty ratio within 2 seconds, and finally outputs a stable PWM signal with the duty ratio DT, so that the current flowing through the load is controlled to slowly increase or decrease. When a load is just connected between the two foils LB1 and LB2 and the polarity is switched, the singlechip module U1 can slowly increase and decrease the current and voltage flowing through the two foils LB1 and LB2 by controlling the output of the 5, 6, 8, 9 and 12 pins of the singlechip module under the action of the internal circuit, and the current mutation in a short time is avoided from stimulating the skin. Generally, after 30-40 minutes of treatment, the human body load (foot or hand) is taken away from the two foils LB1 and LB2, and the whole treatment process is finished.
