Description
Technical Field
The present invention relates to a mask, and more particularly to a mask and a method for ventilating the same.
Background
The protective mask is a respiratory protection article aiming at preventing the transmission of some respiratory infectious microorganisms and protecting the health.
In practice, protective masks include daily protective masks and medical protective masks, wherein the mask body of the daily protective mask is made of a filter material, and a wearer overcomes the resistance of the filter material to air flow by breathing autonomously, so that the mask is called a self-priming filtering respirator. When breathing in, the low air pressure in the mask makes the air flow into the mask; when the respirator breathes out, the air pressure in the respirator is higher than the ambient air pressure, and the air flow is discharged through the respirator. When the mask filter material meets the standard requirements and the mask is sufficiently sealed to the user's face, most of the inspiratory air flow passes through the filter material. The daily protective mask cannot be 100% sealed with the face, which is influenced by various factors such as the shape of the face, the smoothness of the skin, and whether hair is padded under the mask. Most of the particles inhaled by wearing the daily protective mask are leaked, so the close fit of the daily protective mask is the key for ensuring the high-efficiency filter material to play a role.
The medical protective mask consists of a mask surface body and a tightening belt, wherein the mask surface body is divided into an inner layer, a middle layer and an outer layer, the inner layer is common sanitary gauze or non-woven fabric, the middle layer is a superfine polypropylene fiber melt-blown material layer, and the outer layer is non-woven fabric or ultrathin polypropylene melt-blown material layer. The high-efficiency medical protective mask has strong hydrophobic and air permeability, obvious filtering effect on tiny aerosol with virus or harmful dust, good overall filtering effect, and no toxicity or harm of the used materials, and is comfortable to wear.
When the protective mask works, materials for filtering particles comprise mineral fibers, natural fibers or synthetic fibers, and the filter material fibers can comprehensively play a role in filtering particles in air by five mechanisms. Sedimentation: large-particle substances are influenced by gravity in the air flow and are settled on the filter material, and are separated from the air flow; inertial impact action: when the particles in the air flow bypass the filter material fiber blocked in front of the air flow, the particles with higher quality can deviate from the air flow direction under the influence of inertia and collide with the filter material fiber to be filtered; interception: the particles are positioned on the streamline closest to the filter material in the airflow and are intercepted by the filter material due to the fact that the radius of the particles is larger than the distance between the streamline and the filter material; diffusion: under the influence of the thermal motion of air molecules, extremely tiny particles are impacted by the air molecules, the motion direction is continuously changed, brownian motion is presented, and the particles randomly contact with filter material fibers to be filtered; electrostatic interaction: if the filter material fiber has weak static electricity, no matter whether the particles in the air flow are charged with static electricity or not, the particles are easily attracted by the static electricity and filtered when being close to the filter material fiber, and the static electricity can help the filter material to improve the filtering efficiency on the premise of not increasing the resistance of the air flow.
However, in the existing protective mask, the breathing and ventilation are performed and the filtering is performed in a self-inhaling and self-exhaling mode of a wearer during work, and the work mode tends to cause the situations of breath holding, unsmooth breathing and difficult breathing of the wearer, which is a main defect of the conventional technology.
