The beneficial effect is that when wearing the mask, including but not limited to simple and flexible folding and splicing connection method, simple and flexible manufacturing process, low-cost accessories, simple and beautiful appearance, simple and flexible functions.

[0021] like Figure 1 / 2 / 3 / 4 / 5 The interlocking connection includes a magic hook and magic hair connection or / and a convex buckle rib and a concave buckle groove connection, the tight connection includes a convex rib and a groove connection, and the nose tightening fitting includes a forehead support and a side hanging piece, and the forehead support or the side hanging piece can be connected to the connection position on the upper connection area. This means that when the connection position on the upper connection area uses a magic hook, the forehead support or the side hanging piece uses magic hair, when the connection position on the upper connection area uses a convex buckle rib, the forehead support or the side hanging piece uses a concave buckle groove, and when the connection position on the upper connection area uses a convex rib, the forehead support or the side hanging piece uses a groove. The beneficial effect is that only one respiratory mask body can meet the different needs of different patients with a forehead support or a side hanging piece, which obviously reduces the cost.

[0022] To explain: multiple magic hooks or multiple magic hairs gathered into one small piece also belong to multiple matching positions and fall within the technical implementation scope of the present invention; the grooves and concave buckle grooves referred to in the present invention may make the bottom of the groove through in actual implementation, and then they become concave holes and concave buckle holes respectively, which also fall within the technical implementation scope of the present invention.
