Example 2

The embodiment of the present invention provides a reusable mask that can be sterilized at high temperature, including five parts: a mask body 1, an annular buffer sealing assembly 2, a breathing valve 3, an ear-hanging rope 4, and a nose bridge compression strip.

First, as shown in Figures 1 and 2, according to the concave and convex shape of the human face, a mask body 1 suitable for the human face is designed. The breathing valve installation port 11 for installing the breathing valve 3 is reserved on the mask body 1. The breathing valve installation port 11 is provided with There is a reinforced edge, which is beneficial to the firmness and tightness of the breathing valve 3 to be installed. The mask body 1 is provided with a first threaded groove 13 that increases friction and enhances sealing when connected with the annular buffer seal assembly 2, and the mask body 1 is also provided with a buckle 14 that is connected to the ear-hanging rope 4. The mask body 1 Injection molding using ABS plastic and other materials.

Preferably, the mask body 1 can be injection-molded with transparent ABS plastic and other materials to obtain a transparent mask body 1 . With the slow growth of the international economy affected by the plague, social security problems have become prominent. It is normal for people to wear masks. Traditional masks cover a large area of the face, and criminals will take the opportunity to commit crimes, which brings challenges to public security. The mask body 1 can be injection-molded with colorless and transparent materials, which is beneficial to social security management while enhancing the aesthetics.

Further, the annular buffer seal assembly 2 adopts elastic stretchable materials such as rubber latex silica gel. As shown in Figures 3-4, the annular buffer seal assembly 2 is provided with a first thread groove 13 corresponding to the mask body 1. Two threaded grooves 21, the diameter of the annular buffer seal assembly 2 is smaller than the diameter of the mask body 1, so that the second threaded groove 21 can be corresponding to the first threaded groove 13 by stretching, and the tension is released, and the annular buffer seal assembly 2 is the same as the mask. Body 1 is connected. As shown in Figure 4, the annular buffer seal assembly 2 is also provided with a buffer fold pattern 22, which is used to supplement the sealing of the gap between the mask body 1 and the face; the annular buffer seal assembly 2 is also provided with a hollow airbag surface 23 in contact with the face, Makes the face more comfortable and seals better.

Further, as shown in FIG. 5 to FIG. 10 , the breathing valve 3 includes 31 an outer frame of the breathing valve, 32 a filter sheet, and 33 an inner frame of the breathing valve. The outer frame 31 of the breathing valve is provided with a first thread 311 and the inner frame 33 of the breathing valve is provided with a second thread 331. The first thread 311 on the outer frame 31 of the breathing valve and the second thread 331 on the inner frame 33 of the breathing valve can cooperate with each other. Tighten. During installation, the breathing valve outer frame 31 is placed on the inside of the breathing valve port of the mask body 1, and the filter sheet 32 that meets the filtering requirements is placed.
