[0002] In recent years, with the development of society and the improvement of living standards, many smart masks that help breathing have appeared on the market. Compared with ordinary masks, smart masks can effectively solve the problem of uncomfortable breathing caused by wearing traditional masks for a long time. In order to meet the needs of users to monitor various environmental parameters in the mask, the existing technical solutions often connect the mask to mobile devices such as mobile phones through Bluetooth or wifi technology. This technical solution has three defects: first, the connection is completely limited to the mobile device and cannot be used in situations where the mobile device cannot be connected to the Internet; second, the elderly and other groups who are not proficient in smart mobile devices learn to use them, which is costly; third, modern mobile device platforms are numerous and the operating system is complex, and the cost of developing a special APP is high. Therefore, if the problem of mask data transmission can be effectively solved, the mask data parameters can be pushed to the user in a timely manner, and the operation steps can be simplified so that the user can check and control the data at any time, thereby helping the user to timely determine the environment inside the mask and the user's health, the user experience will be greatly improved.

If the working state of the mask system is abnormal (the parameters are abnormal or the system is not working properly), the alarm mechanism is entered. Under this mechanism, the microcontroller 311 uses PWM pulse width modulation to control the vibration of the micro vibration motor 312 at regular intervals, and sends data to the OLED display screen 33 through the IIC bus to display specific error information on the screen. Through this multiple warning method, the user is reminded to pay attention to respiratory health in time.

The user first selects the command through the button module 34 (switching the mask system to automatic mode, adjusting the micromotor gear in manual mode, etc.). After the selection is completed, press the confirmation button. The bracelet part sends the command through the wireless serial port 314. After receiving the command, the mask 4 part parses it and then controls the corresponding components to work according to the command content.
