Embodiment Construction

[0008] Such as figure 1 As shown, the present invention has a mask main body 1 and several restraint belts 2. A soft metal fitting strip 3 is provided at the position where the mask main body 1 fits with the bridge of the nose of the human body. It is characterized in that: there is also an annular silicone seal Circle 4, such as figure 2 As shown, its cross-sectional shape is a "<" type structure, and the "<" type section is swept along an annular sweep line 41 to form the overall structure of the sealing ring, and the annular sweep line 41 and the mask main body The edge line 11 of 1 is consistent; the annular silicone sealing ring 4 is set on the edge of the mask main body 1 through its "<" structure, and when the annular silicone sealing ring 4 is in contact with the human face The surface is set as a convex smooth transition surface 42 .

[0009] The above-mentioned specific embodiments are only exemplary, and are intended to better enable those skilled in the art to u...

Abstract

The invention discloses a silicone sealed mask, which comprises a mask main body (1) and a plurality of binding bands (2), wherein a soft metal fitting strip (3) is arranged at the fitting part of themask main body (1) and the nose bridge of a human body, and comprises also an annular silicone sealing ring (4), the cross section of the silicone sealed ring is a ' ('-shaped structure, and the ' ('-shaped cross section sweeps along an annular sweeping line (41) to form the integral structure of the sealing ring; the annular silicone sealing ring (4) sleeves on the edge of the mask main body (1)through the ' ('-shaped structure, and a convex smooth transition curved surface (42) is arranged on the fitting surface of the annular silicone sealing ring (4) and the face part of the human body;according to the invention, the annular silicone sealing ring sleeves on the mask main body, the mask can adapt to different face curvatures to realize perfect fit, and the annular silicone sealing ring can completely seal the edge of the face under the action of the binding bands, thereby effectively isolating dust and other pollutants.

Description

technical field [0001] The invention relates to a mask, in particular to a protective mask with excellent edge sealing performance, which is especially suitable for mouth and nose protection occasions with high dust and high pollution. Background technique [0002] At present, the masks on the market generally use non-woven fabric as the main part of the mask. According to the general structural characteristics of the human face, it is pressed into a shape that fits the curvature of the human face, and then the elastic band is used to tighten the main body of the mask to make it fit. on the human face. However, the facial curvature of the human body varies from individual to individual, and the existing mask structure cannot meet the facial curvature characteristics of all individuals, resulting in poor sealing of the edge of the mask, and the inability to effectively exert the dust-proof and anti-pollution effect of the mask. Contents of the invention [0003] In order t...
