Description

Harmful gas isolation protective mask with anti-drop structure

Technical Field

The utility model relates to a protective facial mask equipment technical field, more specifically say, relate to a harmful gas isolation protective facial mask with anti-drop structure.

Background

The protective mask is a respiratory protection article aiming at preventing the transmission of some respiratory infectious microorganisms and protecting the health.

The mask body of the daily protective mask is made of a filtering material, and a user overcomes the resistance of the filtering material to air flow by autonomous respiration, so the mask is called as a self-absorption 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. In order to reduce leakage, the daily protective mask must be designed into a solid structure, and a certain pressure is applied by the headband and the nose clip to make the mask tightly fit with the face.

The existing protective mask is simply worn by having an elastic rope, does not have a certain anti-falling structure, is easy to fall off, easily causes infection and propagation of a user, and greatly reduces the protective performance of the mask.
