AI Technical Summary
In existing breathing masks, gaps can easily form at the connection between the frame and the air intake tube due to wear and other reasons, leading to gas leakage and noise, which affects the user's experience.
Flexible connectors are used to seal the connection with the frame and the intake pipe. The flexible connectors achieve a tight fit through their own elastic deformation and disperse displacement stress when the intake pipe is offset, thus avoiding the formation of gaps.
It effectively maintains a reliable seal between the frame and the air intake pipe, preventing gas leakage and noise, and improving the user experience.
