Description

Title of Invention: A mask sealing strip fitting mechanism

Technical field

[0001] The present invention relates to a mask sealing strip fitting mechanism.

Background technique

[0002] At present, in order to make the mask and the nose fit better, a mask strip (x2), that is, a metal strip, is used, and the clip is formed by pressing the clip (x2) so that the mask is formed between the nose and the nose. There is a good fit curve. In order to better maintain the mask tightness, many masks are attached with a sponge strip behind the clip nose (x2) on the inside of the mask, as shown in Figure 1. The back of the sponge strip is glued to the inside of the mask and the clip strip.

(x2) The position corresponds. This construction is only suitable for short-term and dry environments. For long-term use in high-grade masks, the pinch (x2) and sponge strips are easy to remove. It is a sponge strip. The wet mask will cause the adhesion between the backing and the non-woven fabric to decrease, which will be adjusted down, which greatly affects the quality. Therefore, the applicant designed a clip strip (x2) and a sealing strip. (x4) - Body seal strip (x4), replacing the sponge strip (x3) with a soft rubber strip, with a top bulge (x5), a rubber strip embedded with a metal strip, and a tenon (x5) And through the mask, and then with a rubber back strip (x6), it is riveted together, so the applicant also designed a machine that fits the seal (x4).
