Breathing mask conforming to human body engineering science design and design method thereof

The invention relates to a respiratory mask which is in line with the ergonomic design and an design method thereof, including a mask body with the facial three-dimensional characteristics, the respiratory mask is characterized in that: the mask body has 28 physiological characteristic points and product characteristic points, the contact position of the mask body and the face forms a three-dimensional characteristic curve, the middle transition part of the mask body is a curve, a respiratory rhythm, an alarm indicator and an anti-gas leak partition board are arranged on the respiratory mask. The respiratory mask extracts the characteristic points to establish the three-dimensional characteristic curve according to a human face three-dimensional model, the mask is closely attached to the face, and the oppression on the face is reduced simultaneously, therefore the respiratory mask is applicable to those who need the long-term non-invasive respiration for usage.
