Description

Technical Field

[0001] This utility model relates to the field of control circuit technology, and in particular to a control circuit for a breathing trainer. Background Technology

[0002] Breathing trainers, as important devices in the field of medical rehabilitation, aim to help users strengthen their respiratory muscles, improve breathing rhythm, and increase lung capacity by simulating different breathing patterns, thereby accelerating the recovery of the respiratory system. One of its core components—the control circuit—plays a crucial role. The control circuit is not only responsible for receiving breathing data collected by sensors, but also for processing and analyzing this data according to preset training modes, ultimately controlling the breathing training through the actuator.

[0003] Existing breathing trainers have significant shortcomings in observing the user's breathing training progress. This deficiency mainly stems from the lack of intuitive feedback mechanisms in the design of traditional breathing trainers. During training, users often cannot understand their breathing status in real time. The lack of intuitive visual or auditory feedback mechanisms makes it difficult for users to understand their breathing status in real time. Due to the lack of immediate feedback, users find it difficult to adjust their breathing methods in a timely manner, thus affecting the improvement of training effectiveness. Utility Model Content

[0006] To achieve the above objectives, one embodiment of this utility model provides a breathing trainer control circuit, including a microcontroller U1, a TYPE-C charging circuit, a charging detection circuit, an analog-to-electronic conversion circuit, a speaker control circuit, and an indicator light control circuit. The speaker control circuit includes a microcontroller U2 and a speaker S1. The microcontroller U2 controls the opening and closing of the speaker S1. Terminals 1 and 2 of the speaker S1 are connected to the PWM1 and PWM2 pins of the microcontroller U2, respectively. Pins TG2 and TG1 of the microcontroller U2 are connected to pins PA3 and PA4 of the microcontroller U1, respectively. The analog-to-electrical conversion circuit includes a microcontroller U3, which converts the respiratory analog signal into an electrical signal. The input terminal of the microcontroller U3 is connected to a terminal VADC, which is connected to pin PA7 of the microcontroller U1. The TYPE-C charging circuit includes a TYPE-C6P charging chip, which can charge the power supply. The charging detection circuit includes a microcontroller U4.

Resistors R11, R8, and R7 are connected in series between the RGB-B, RGB-G, and RGB-R terminals and the indicator control chip RGB1, respectively. The RGB-B, RGB-G, and RGB-R terminals are connected to pins PB4, PB3, and PB2 of the microcontroller U1, respectively.

[0008] Preferably, in any of the above schemes, the speaker control circuit further includes a capacitor C1 and a resistor R15. The capacitor C1 is connected to the VDD pin of the microcontroller U2, and the resistor R15 is connected in series between the PWM2 pin of the microcontroller U2 and the second terminal of the speaker S1.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. The main function of the analog-to-digital conversion circuit is to convert analog signals (such as continuously changing physical quantities like breathing pressure and flow rate collected by the breathing trainer's sensors) into digital signals, and then transmit the digital signals to the microcontroller U1. Microcontroller U1, in conjunction with microcontroller U2 in the speaker control circuit, controls the speaker S1. Simultaneously, the indicator light control circuit controls the on / off state of various indicator lights. Adding indicator lights and speaker S1 to the breathing trainer provides feedback by visually displaying the user's breathing status through color changes and sound cues. When the breathing rate is too fast or too slow, the indicator light can change color or increase its flashing frequency to remind the user to adjust their breathing rhythm. Speaker S1 further provides auditory feedback through different sounds or tones. When the breathing training reaches the preset goal or needs adjustment, speaker S1 emits a specific sound signal to guide the user to perform the corresponding operation. This instant feedback mechanism not only improves the targeting and effectiveness of the training but also enhances the user's training experience and engagement.

This provides users with more charging options and reduces charging problems caused by interface incompatibility. The charging detection circuit monitors the charging current and voltage in real time, ensuring they remain within safe ranges. This helps prevent battery damage or safety accidents caused by excessive current or voltage. Once the battery is fully charged, the charging detection circuit automatically cuts off the charging current to prevent overcharging. This helps extend battery life and reduces safety hazards caused by overcharging. Attached Figure Description
