A kind of active ventilation mask ventilation method and mask ventilator

Abstract

The invention discloses an active ventilation mask ventilation method and a mask ventilator, which comprises the following steps: (1) setting a mask; (2) setting a mask ventilator; (3) people put on a mask and turn on the mask through a rotary switch The strip opening of the ventilator is controlled by the single-chip controller to control the rotation of the driving motor; (4) when the human body exhales, the driving motor drives the fan blade to rotate, and the exhaust gas exhaled by the human body is discharged between the mask and the human body; (5) the human body breathes When the air is exhausted, the drive motor stops rotating or reduces the rotation speed, and the outside air enters through the filter material of the mask; (6) the active ventilation of the mask is realized. The invention also discloses a mask ventilator. The invention actively extracts the exhaust gas exhaled by the human body from the mask and the mouth and nose through the mask ventilator, which is beneficial to keep the air between the mask and the face dry and comfortable, and avoids the discomfort of breathing and wearing caused by humidity and sultry heat.

Description

technical field [0001] The present invention relates to the technical field of masks, in particular to an active ventilation mask ventilation method, and a mask ventilator implementing the method. Background technique [0002] Masks are a common daily necessities in life, which can block harmful particles, gases, odors, and droplets from entering and leaving the wearer's mouth and nose. [0003] In the current society, with the development of industrialization, the popularization of automobiles, the increase of germs, and the pollution of heavy metals, air pollution is becoming more and more serious. Formaldehyde exceeds the standard in many areas, and haze weather increases, which is very detrimental to human health, especially The PM2.5 in northern and other regions is seriously exceeding the standard. With the increasingly severe haze weather, the harm to human health, especially the respiratory tract, is more and more prominent. Masks have almost become a must when goi...
