Description

Technical Field

[0001] This utility model belongs to the field of massage, and specifically relates to a cold compress and massage circuit. Background Technology

[0002] Cold compresses are a treatment method in the medical system, which involves applying ice packs or cold, damp towels to the skin on the forehead, back of the neck, or affected area. The main purpose of applying them to the affected area is to promote local vasoconstriction, control bleeding from small blood vessels, and reduce pain from tense lumps, thus achieving the effect of reducing swelling and relieving pain. For patients with high fever, applying them to the forehead and back of the neck can lower body temperature and improve discomfort.

[0003] Based on existing research, common methods of cold compress include using ice packs, cold water towels, cold water bottles, cold water immersion, cold compress gels, cold compress patches, and cold compress sprays to achieve the therapeutic effect. However, these methods still have the following problems:

[0004] 1. Non-recycling problem: For existing cold compress methods, if items such as ice packs, cold water, and cold compress gel are used up after use, they cannot meet the user's need for continued cold compresses, and it is necessary to replace the cold compress items. This method makes the products non-recyclable and the cost is high.

[0005] 2. Lack of portability: Currently available cold compress products require certain storage conditions and cannot be used anytime and anywhere, thus lacking portability.

[0006] 3. Technological innovation can no longer meet the ever-evolving needs of users: With the development of society, users' needs for cold compresses are becoming more and more diversified, and the simple technology used in traditional cold compress methods can no longer meet the ever-evolving needs of users.

[0007] 4. Limited functionality: Traditional cold compress methods have relatively simple functions, often only having basic cold compress functions.

[0008] 5. Insufficient cold compress effect: Traditional cold compress methods cannot achieve the effect of sub-zero degrees Celsius and cannot quickly achieve the effect of cold compress. Utility Model Content

[0070] In this embodiment, the circuit also includes a button module 7 for inputting operation commands, and the button module 7 is electrically connected to the main control chip 1.

[0071] In this embodiment, see Figure 3 This is the circuit schematic of the main control chip 1. The main control chip 1 uses the SC8P062EA chip and is packaged in SOP16.

[0072] The main control chip operates at a voltage range of 1.8V to 5.5V (pin 1), powered by an internal battery or an external power supply.

[0073] The main control chip 1 is connected to the digital tube screen 3 by 5 signal lines (pin 3, pin 5-pin 8). Through the coordinated cooperation of the 5 signal lines, it ensures that commands and data can be correctly sent to the digital tube screen 3 and the display of the digital tube screen 3 can be controlled to achieve the expected display effect.

[0074] The current battery level can be detected by the reference voltage inside the main control chip 1. By detecting the ADC of the internal reference voltage in real time, the current battery voltage can be obtained. After data conversion, the current battery level is displayed on the digital tube screen 3. Temperature detection and display are also achieved by detecting the ADC value of the NTC pin.

[0075] The pinouts of main control chip 1 are described in detail below:

[0076] a. Pins 3 and 5-8 are used to control the display of the digital tube screen 3;

[0077] b. KEY (pin 2), button IO, identifies whether there is a button operation by judging the level change of the IO;

[0081] f.TG1 (pin 11): The main control chip 1 sends a pulse signal to the voice broadcast chip through this IO to control the voice broadcast chip to play audio reminders.

[0082] g. Massage module (pins 12-15): The main control chip 1 uses this part of the I / O to control the massage patch to work.

[0083] In this embodiment, see Figure 4 This is the circuit schematic diagram of part 2 of the charging circuit;

[0084] Specifically, it uses the AK4056H chip as the lithium battery charging chip, with a maximum charging current of 1000mA; it uses resistors R6 and R4 to form a USB plug-in / plug circuit, and the TDC terminal connected between resistors R6 and R4 is used to detect the plug-in / plug-out status of USB1; the CHRG terminal of the charging chip is used to send the signal output by the charging chip indicating whether charging is complete to the main control chip 1, and the main control chip 1 performs the corresponding operation after receiving the signal.

[0085] In this embodiment, see Figure 5 The interface part of the digital tube screen 3 consists of 18 LEDs. When the main control chip 1 receives a specific signal, it can issue specific instructions to drive the LEDs to display specific lighting effects and the digital tube screen 3 display, which can display the current power, temperature, charging lighting effects, etc. in real time.

[0086] In this embodiment, see Figure 6This is the circuit schematic of the massage patch driver module 4. The BOOST1 pin outputs a waveform to achieve a voltage boost effect for the massage patch. Simultaneously, an H-bridge is used with the MOTOR_L1 and MOTOR_R1 pins. An H-bridge circuit is used to control the direction and speed of a DC motor. Its basic structure consists of four switching elements, specifically transistors, forming an "H"-shaped current path. By controlling the on and off states of these switching elements, functions such as forward rotation, reverse rotation, and speed adjustment of the motor can be achieved. Specifically, when MOTOR_L1 is on, MOTOR_R1 needs to be off. At this time, Q3 and Q7 are on, and the current flows sequentially through Q3-OUT1- When MOTOR_R1 is on, MOTOR_L1 needs to be off. At this time, Q6 and Q4 are on, and the current flows through Q6-OUT1-OUT2-Q4 in sequence. By continuously switching the two pins, the voltage / current at the connected load or output terminal can be reversed. After the current is boosted by BOOST1, it is output to the J1 load massage patch through the H bridge. When the massage patch comes into contact with the human skin, it will generate a conducting current, thereby achieving the massage effect. Each time the conduction channel is switched, it will be discharged through the Buck pin to avoid the voltage from accumulating after boosting and causing damage to the device, and to prevent damage caused by excessive boosting.

[0087] In this embodiment, see Figure 7 , Figure 8 These are the cooling chip drive module 5 and the fan drive module 6, respectively.

[0088] exist Figure 7 The system uses a JXP3400VRG MOSFET Q8, supporting a maximum current of 6A and a maximum voltage of 30V. When the user uses the system, the main control chip 1 receives a command and outputs a corresponding waveform signal through this I / O pin to control the MOSFET Q8 to conduct. When the MOSFET Q8 is on, electrical energy can flow through it to the cooling chip, causing the cooling chip to start working and achieve the cooling effect. The main control chip 1 can precisely adjust the cooling power of the cooling chip by precisely controlling the duty cycle and frequency of the waveform signal, so as to provide different cooling temperature effects according to the user's needs.

[0089] The NTC terminal of the cooling chip drive module 5 can also be connected to a thermistor. The thermistor's resistance changes at different temperatures, which can feed back an ADC signal to the main control chip 1. The main control chip 1 detects the ADC signal to confirm the current cooling temperature, so as to adjust the cooling power of the cooling chip by controlling the duty cycle and frequency of the waveform signal.

[0090] exist Figure 8 In this circuit, the MLS2302D MOSFET Q11 is used, which supports a maximum current of 3A and a maximum voltage of 12V.

[0091] When the user uses the device, the main control chip 1 receives the instruction and outputs the corresponding waveform signal through the IO pin to control the conduction of the MOSFET Q11. When the MOSFET Q11 is turned on, electrical energy flows through it to the fan drive motor, causing the fan to start working and achieving the effect of heat dissipation.

[0092] In this embodiment, see Figure 9 The circuit diagram for button module 7 is shown below. One end of the button is connected to the power supply, and the other end is connected to a GPIO pin of the main control chip 1. When the button is pressed, the main control chip 1 receives a low-level signal to control the switching of the power output level in this example. The main control chip 1 continuously monitors the button's state. Once it detects a change in the electrical signal caused by the button being pressed, the main control chip 1 immediately recognizes this operation and executes the corresponding function according to the preset program.

[0093] In this embodiment, see Figure 10 The voice broadcast module 8 includes a V58170_AA voice broadcast chip. It receives pulse signals from the main control chip 1 via an I / O port. After the main control chip 1 sends a pulse signal to the voice broadcast chip, the chip parses the pulse signal and automatically plays the corresponding audio. After playing the audio, it automatically enters a low-power mode. The voice broadcast chip supports 8Ω 0.5W and 16Ω 0.25W speakers and can be directly connected to the speaker for audio output via PWM1 and PWM2 pins. Alternatively, other existing voice broadcast chips can also be used.

[0094] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
