Description

A mask Technical field

The invention relates to the technical fields of medical equipment, labor protection articles, and cold-proof equipment, in particular to a face mask.

Background technique

Many face masks are used in medical treatment, some are anti-virus and some are dust-proof, but at present, the face mask is 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 example, in China, some medical staff wear face masks to prevent the virus from being inhaled. Due to the poor sealing, they are tightly strangled. As a result, their faces are strangled with marks.

Because the shape of the human body's face is different, for example, the Asians have a lower nose bridge and a wider face; while Westerners have a higher nose bridge and a narrower face, it is difficult to make a mask fit everyone's face completely.

Preferably, the goggle body 33 is further provided with a goggle extension 35, and the goggle extension 35 is in contact with the temple of the head, as shown in FIG. 5.

Preferably, the liquid balloon is filled with gas and/or liquid in its cavity, and the volume of the gas and/or liquid filled in the cavity of the liquid balloon at room temperature and pressure is smaller than that of the cavity at room temperature and pressure. The maximum volume that can be filled. For example, the maximum volume that can be filled inside a liquid balloon refers to the volume of the liquid balloon when the gas and/or liquid pressure in the liquid balloon is equal to one atmospheric pressure and the temperature is 20 degrees Celsius, that is, the liquid balloon can be filled with the most water. volume of. When in use, the volume of the inflated body and/or liquid in the cavity of the liquid airbag under normal temperature and pressure is smaller than the maximum volume that the cavity can be filled under normal temperature and pressure. This is because the liquid air bag is a non-elastic sealed air bag. If it is elastic, the volume of gas in the liquid air bag is uncertain and can fill the entire liquid air bag. That is to say, if the liquid balloon is elastic, the gas and/or liquid in it can be incomplete, and the inflatable body and/or liquid can be selected to be one-third to two-half. One, it can also be full, or even too high, so that the pressure in the liquid balloon is greater than a standard atmospheric pressure. Normal temperature and normal pressure refers to a standard atmospheric pressure and a temperature of 20 degrees Celsius. For example, the inflated body and/or liquid in the cavity of the liquid balloon can be gas, liquid, or liquid plus gas. The volume of the inflated body and/or liquid in the cavity of the liquid balloon refers to gas and The sum of the volume of liquid, the volume of gas is calculated as the volume of gas, the volume of liquid is calculated as liquid, and the volume of both gas and liquid is calculated as the sum of the two volumes.

It can be charged before the sale or while the customer uses it. For example, because the liquid air bag is not filled with gas, the liquid air bag can bulge up at the place where there is a gap between the mask and the human body under a small external force, and deflate at the place where there is no gap between the mask and the human body, so that the mask and the human body can be fully attached.合, thus a complete seal. If it is an elastic liquid balloon, the liquid balloon can be filled with gas and/or liquid. However, to make the mask body 1 fully fit the human body, a relatively large external force is required.

The maximum radius of the liquid balloon is R after being filled with liquid or gas, so the liquid balloon can fill the gap between 0-2R. If the balloon is a multi-layer liquid balloon and there are N layers of liquid balloon, then the gap between 0-2NR can be filled in the balloon.
