Description

Mask device

This invention is a mask device, especially a mask device that can be worn by a user and can extract the gas inside the mask to provide a ventilation function.

Nowadays, people will wear masks and use masks to block most of the dust, germs and other harmful substances in the air, so as to prevent people from inhaling harmful substances in the air during breathing or talking.

Among them, the traditional mask mainly includes a mask body and ear straps respectively arranged on both sides of the mask body. It is fixed on the face and covers the mouth and nose, and forms an internal space between the mask body and the face. Therefore, in an ideal state, when the user wears the mask and inhales, the internal space inside the mask body will A negative pressure is formed, so that the external air will pass through the filter of the mask body and enter the internal space, thereby filtering the external air to prevent harmful substances in the air from being inhaled by the user, and when the user exhales, the user The exhaled carbon dioxide will be discharged from the peripheral gap of the mask body.

But in fact, when the user wears a mask, the carbon dioxide produced in the breathing process will enter the internal space of the mask body during the exhalation process, and part of the carbon dioxide and air in the internal space will flow out of the mask body. The outer gap is discharged, and most of the carbon dioxide will still remain in the inner space, so that when the user wears the mask for a long time, it is easy to feel asphyxiated due to the high concentration of carbon dioxide in the inner space of the mask.
