The liquid air bag (2) is used in the case that the volume of gas and/or liquid and/or deformable solid filled in a cavity of the liquid air bag at the normal temperature and pressure is less than the maximum volume that the cavity can be filled at normal temperature and pressure, or that the cavity is not filled with the gas and/or liquid and/or deformable solid but a filling hole (3) is provided and that there is a hint that the volume filled at the normal temperature and pressure is less than the maximum volume, which can be filled with the gas and/or liquid and/or deformable solid, in the cavity of the liquid air bag at the normal temperature and pressure; and the sealing object body (1) is connected to the liquid air bag (2). By providing the underfilled liquid air bag (2) at the edge of the sealing object body (1), and because the gas and/or liquid and/or deformable solid in the liquid air bag (2) can move, the liquid air bag (2) can be bulged at a place having a gap and recessed at a place without a gap, thereby sealing the face of a human body and the sealing object body (1) and preventing air from entering and exiting through the gap.

Description

A kind of sealing structure

Technical field

The invention relates to the technical field of medical equipment and labor protection products, in particular to a sealing structure.

Background technique

Many protective masks are used in medical treatment, some are anti-virus and some are dust-proof, but the current masks are not closely attached to the human face, so that dust and viruses enter the respiratory tract and cause the mask to lose its proper function. For now, this problem has been noticed and some measures have been taken, such as setting up an iron clip on the bridge of the nose and pinching the iron clip when wearing a mask to fit the bridge of the nose, but this iron clip will become loose. Fatigue, using iron clips cannot completely prevent dust and viruses from entering the gap between the mask and the face.

In order to prevent the inhalation of the virus, some medical staff wear a four-layer mask, but the result is still infected with the virus. The reason is not that the mask is not well protected, but that the breathability of the mask is poor after wearing the four-layer mask. The air enters directly from the gap between the mask and the face, which is worse than wearing a mask at this time.

Due to the different facial shapes of the human body, such as the lower nose bridge of Eastern people and the higher nose bridge of Westerners, it is difficult to make a mask fit everyone's face completely. There are also gas masks, waterproof glasses, dust-proof masks, breathing masks, fire-fighting masks and other items that also need to be sealed with the human face.

Detailed ways

The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

In order to further illustrate the embodiments, the present invention is provided with drawings. These drawings are a part of the disclosure of the present invention. They are mainly used to illustrate the embodiments, and can cooperate with the relevant descriptions in the specification to explain the operating principles of the embodiments, with reference to Those of ordinary skill in the art should be able to understand other possible implementation manners and advantages of the present invention from these contents. The components in the figure are not drawn to scale, and similar component symbols are usually used to indicate similar components.

With reference to the accompanying drawings, a sealing structure includes a sealed object body 1, the edge of the sealed object body 1 contacting the face is provided with a liquid balloon 2 which is a thin-walled balloon with a cavity inside, so The liquid balloon 2 is filled with gas and/or liquid and/or deformable solid in its cavity, and the liquid balloon 2 is filled with gas and/or liquid and/or deformable solid in its cavity. The volume under normal temperature and pressure is less than the maximum volume that the cavity can be filled under normal temperature and pressure, or there is no gas and/or liquid and/or deformable solid filled but there is a hint that the volume filled under normal temperature and pressure is less than its empty The cavity is used after the cavity can be filled with the largest volume of gas and/or liquid and/or deformable solid that can be filled under normal temperature and pressure. The sealed object body 1 is connected to the liquid balloon 2, and the liquid balloon 2 is placed on the sealed object body Between 1 and the face, as shown in Figure 1.

Preferably, the volume of the gas and/or liquid and/or deformable solid filled in the cavity of the liquid balloon 2 at room temperature and pressure is six minutes of the maximum volume that the cavity can be filled at room temperature and pressure. One to five-sixths and/or the liquid balloon 2 is provided with a filling hole 3 to fill the cavity of the liquid balloon 2 with a volume under normal temperature and pressure to the maximum that the cavity can be filled under normal temperature and pressure One-sixth to five-sixths of the volume of gas and/or liquid and/or deformable solid. For example, the maximum volume that can be filled inside the liquid balloon 2 refers to the volume that the liquid balloon 2 can fill when the gas and/or liquid pressure in the liquid balloon 2 is equal to one atmospheric pressure and the temperature is 20 degrees Celsius, that is, the volume that the liquid balloon 2 can fill. Fill the volume with the most water. When in use, the volume of the inflated body and/or liquid in the cavity of the liquid airbag 2 under normal temperature and pressure is smaller than the maximum volume that the cavity can be filled under normal temperature and pressure.

This is that the liquid balloon 2 is non-elastic. If it is an elastic liquid balloon 2, the volume of gas in the liquid balloon 2 is uncertain, and the entire liquid balloon 2 can be filled.
