[0048] The core of this utility model is to provide a control circuit and a therapeutic device. The communication module directly connects the controller to the server, and the card swiping information on the server can be directly sent to the controller to avoid problems caused by card swiping. Then, the electrical stimulation module can output electrical stimulation to the electrode pads to achieve treatment for the user. The storage module also stores the card swiping information for easy data storage.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0051] Power module 1 has its input end connected to an external power source and its output end connected to controller 5, electrical stimulation module 2, communication module 3 and storage module 4 respectively, for power supply.

[0052] The electrical stimulation module 2 has a control terminal connected to the controller 5 and a power supply terminal connected to the power module 1, and is used to output electrical stimulation to the electrode pads.

[0053] Communication module 3, connected to controller 5, is used to connect controller 5 to the server so that controller 5 can control electrical stimulation module 2 based on the received card swipe information;

[0054] Storage module 4, which is connected to controller 5, is used to store card swipe information;

[0055] Controller 5.

[0056] Current products and patents use IC cards for billing, which makes the device incompatible with different devices in terms of hardware. Furthermore, it can lead to billing errors due to strong magnetic fields or other harsh environments. During use, user error can also cause billing errors.

[0057] Therefore, this application includes a communication module 3, which connects the controller 5 to the server. Instead of directly swiping the IC card, the card swipe information is received directly from the server, avoiding magnetic field interference. After the user inputs the card swipe information on the server, it is transmitted to the controller 5 via the communication module 3. The controller 5, upon receiving the card swipe information, performs the same steps as in existing technologies, controlling the electrical stimulation module 2 according to the preset control logic. The storage module 4, connected to the controller 5, stores the card swipe information, providing a data basis for subsequent user queries or calculations.

[0058] Specifically, when controller 5 receives card swipe information, such as ten treatments remaining, it controls electrical stimulation module 2 to perform treatment, and then modifies the number of treatments to nine remaining and saves it to storage module 4, thus completing a full treatment. This process is the same as that of a physical card.

[0059] Considering the power supply issue of the control circuit of the therapeutic device, a power module 1 is set up. The power module 1 adjusts the external power supply to the voltage required by the controller 5, the electrical stimulation module 2, the communication module 3 and the storage module 4, such as 12V, 5V, 3.3V or -5V, which can be adjusted according to actual needs.

[0060] In other words, the functions of each module are as follows:

[0061] Power module 1: Provides power to the entire device, using 220V AC mains power.

[0062] Controller 5: Uses MCU (Micro Control Unit) to control the entire device.

[0063] Electrical stimulation module 2: According to the instructions of the MCU, it outputs an asymmetric square wave electrical stimulation signal with adjustable frequency, time and pulse width of carrier wave.

[0064] Communication module 3: The local device interacts with the server via MQTT (Message Queuing Telemetry Transport).

[0065] Storage Module 4: Data is stored via IIC (Inter-Integrated Circuit), using a dedicated storage chip to enhance device stability.

The communication module 3 is connected to the controller 5, connecting it to a server for receiving card-swiping information. The storage module 4 is connected to the controller 5 and stores the card-swiping information. The communication module 3 directly connects the controller 5 to the server, allowing the server-side card-swiping information to be directly sent to the controller 5, converting physical cards into virtual card-swiping information. This avoids the problem of physical cards becoming invalid or lost, allowing the electrostimulation module 2 to output electrostimulation to the electrode pads for treatment. The storage module 4 also stores the card-swiping information for data storage.
