[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4As shown, an embodiment of the present specification provides a circuit system for an anal care device, including a main control module 11 and a power management module 2, an electromagnetic load driving module 3, and a user interaction module 4 connected to the main control module 1, wherein: the power management module 2 is used to manage the charging and discharging of the battery, so as to supply power to the main control module 1, the electromagnetic load driving module 3 and the user interaction module 4; the electromagnetic load driving module 3 includes a boosting unit, a release unit and a channel switching unit controlled by the main control module 1, the boosting unit is used to boost the power supply of the power management module 2 so that the boosted voltage can drive the care device, the release unit is used to periodically release the boosted voltage to the ground, so that the care device works periodically, and the channel switching unit is used to switch between different release units; the user interaction module 4 is used to feedback to the main control module 1 when its own button is triggered, so that the main control module 1 performs corresponding control on the electromagnetic load driving module 3.

[0022] The electromagnetic load detection module also includes a load detection unit, which is used to detect whether the nursing device is connected. The main control module 1 includes a SOC Bluetooth chip, and the main control module 1 is also used to connect to the external device via Bluetooth to receive wireless data during Bluetooth interaction. The nursing device is an electromagnetic sticker, which is connected to the nursing device through Figure 4 The output voltage of the OUT1-OUT2 interface or the D- to D+ TYPE-C interface is driven.

[0023] Among them, Figure 2As shown, the electromagnetic load driving module 3 includes a boost unit, a discharge unit, a load detection unit and a channel switching unit. The discharge unit also includes two discharge loops, a dual discharge loop and a single discharge loop, wherein the dual discharge loop includes a left discharge channel and a right discharge channel. The single discharge channel includes a single discharge channel. The transistor Q3, inductor L3 and transistor Q2 controlled by the signal MOTO_Boost constitute a boost unit. By controlling the duty cycle of MOTO_Boost, the VCC_BAT voltage rises; the signal MOTO_Buck and the transistor Q4 constitute the basic function of the pressure release unit. After the signal MOTO_Buck turns on the transistor Q4, the boosted power supply is directly released to the ground; the NMOS tubes Q8, Q6 and Q11 controlled by the signal MOTO_L constitute the left discharge channel of the dual discharge loop, and the NMOS tubes Q10, Q9 and Q7 controlled by the signal MOTO_R constitute the right discharge channel of the dual discharge loop. The pin LOAD_DET, the resistor R59, the left and right discharge channels, and the human body load constitute a load detection unit. When there is a load, no matter the current passes through the left discharge channel or the right discharge channel, it will eventually flow into GND through the resistor R59. At this time, the resistor R59 performs current limiting and voltage division. The pin LOAD_DET can detect the level signal of the resistor R59 to judge the load: when there is no effective load connected, the pin LAOD_DET is connected to the ground through the weak pull-down resistor R59, which is a low-level signal; when there is an effective load connected to the circuit, the LOAD_DET circuit is at a high level. At this time, the main control module 1 can detect whether there is an effective load connected to the circuit, and then determine whether to perform a series of subsequent discharge care work. The single-channel discharge ring is similar to the dual-channel discharge ring, but because there is only one discharge channel, the discharge efficiency is lower than that of the dual-channel discharge circuit. In this way, the switching between the single-channel discharge ring and the dual-channel discharge ring can more accurately control the discharge power. When the dual-path release ring and the single-path release ring need to release pressure, the pressure release unit composed of the signal MOTO_Buck and the transistor Q4 will turn on the transistor Q4, and the high-voltage energy will be released to GND.

[0024] In addition, the meaning of releasing electricity is to release the high-voltage charge. When massaging, general electromagnetic care equipment will connect massage patches to the output end of tpye-C and OUT1 / OUT2, and stimulate the human body through micro-current to achieve massage effect. If the high-voltage charge is continuously used, this is a static voltage, and the rhythmic massage effect cannot be achieved. Only by continuously charging and releasing the boost unit and the release unit can a changing current be formed to produce different simulated scraping, acupuncture, and kneading effects.

[0025] like Figure 3As shown, the main control module 1 can use a Bluetooth chip U4 of model SYD8810 BLE. In the exemplary application, multiple pins such as GPIO0 to GPIO30 can be used, among which the GPIO0 pin is used as a Buck pin for the release control of the release loop after boosting, mainly controlling the transistor Q4 to release the high-voltage energy. GPIO1 is used for the release power control of the left channel of the release loop, mainly used to drive the NMOS tube Q8 to realize the conduction of the left release loop, and form a loop with the human body to realize power release. The GPIO4 pin is an ADC pin, which is mainly used to detect the voltage signal of the battery. The Bluetooth chip can obtain the remaining power and charging status of the current battery by detecting the battery voltage chip. The GPIO5 pin is used as the load detection pin of the dual output channel. The GPIO6 pin is used for the power release control of the right channel of the release loop. GPIO9 is used for the boost control of the boost unit. The GPIO10 pin is used to control the buzzer. GPIO19, GPIO12, and GPIO16 are used as control pins for indicator lights. GPI012 is used as a load detection pin for a single-channel release ring. GPIO15, GPIO18, and GPIO20 are used as key pins for user interaction module 4.

[0026] like Figure 4 As shown, the power management module 2 includes a charging chip and a voltage regulator chip. The charging chip U1 uses the LP4054H charging management chip to implement the charging management of the lithium battery. Its PIN1 is the CHRG pin, which is connected to the GPIO22 of the Bluetooth chip U4 to realize the information notification of the charging status. PIN5 is the charging programming pin. A resistor is connected in series between this pin and GND to realize the control of the charging current. The voltage regulator chip U3 mainly includes the LN1132 LDO circuit, which stabilizes the battery voltage to 3.3V for powering the Bluetooth chip U4.

[0027] Among them, based on the electromagnetic load driving module, its boost and release can be started alternately. The circuit is simple and can achieve the effect of simulated massage without expensive driving chips, so the cost is low.
