Abstract

The invention discloses a sealing structure, which comprises a sealing object body and a liquid air bag. The volume of the gas and / or liquid and / or deformable solid filled in the cavity of the liquid air bag at room temperature and pressure is less than the maximum volume that the cavity can be filled at room temperature and pressure, or there is no gas and / or liquid and / or deformable solid gas and / or liquid and / or gas and / or liquid and / or liquid but provided with filling holes and indicating that the volume filled at room temperature and pressure is less than the maximum volume that the cavity can be filled at room temperature and pressure, after the deformed solid is used, the body of the sealed object is connected with the liquid air bag. The liquid air bag which is not fully filled is arranged on the edge of the sealing object body, air and / or liquid and / or deformable solid in the liquid air bag can move, the liquid air bag can bulge at the position with a gap and can sink at the position without a gap, and therefore the space between the face of the human body and the sealing object body is sealed, and air is prevented from entering and exiting from the gap.

Description

technical field [0001] The invention relates to the technical field of medical equipment and labor protection articles, in particular to a sealing structure. Background technique [0002] Many protective masks are used in medical treatment, some are anti-virus and some are dust-proof. However, the current masks are not tightly fitted to the human face, so that dust and viruses enter the respiratory tract and cause the masks to lose their proper functions. For now, this problem has been noticed and some measures have been taken, such as setting an iron clip on the bridge of the nose. When wearing a mask, pinch the iron clip so that it fits the bridge of the nose, but the iron clip will loosen. Fatigue, the method of using iron clips cannot completely prevent dust and viruses from entering from the gap between the mask and the face. [0003] Some medical staff wear four-layer masks to prevent virus inhalation, but they are still infected with the virus. The reason is not that...
