Of course, the material of the sealing portion 22 may be a combination of two or more materials. For example, the portion of the sealing portion 22 that contacts the patient is made of a softer material, and the portion away from the patient is made of a harder portion. In addition, the material of the fixing portion 21 may be the same as that of the sealing portion 22. Of course, the material of the fixing portion 21 may also be different from that of the sealing portion 22, and the embodiment of the present application does not limit this.

[0060] In addition, in the embodiment of the present application, the molding method of the liner assembly 20 includes but is not limited to injection molding, cutting, 3D printing and other molding methods.

[0066] In addition, in the embodiment of the present application, the first retaining portion 42 is an arc-shaped plate structure, and the arc-shaped plate structure can be bent into a semi-cylindrical shape. At this time, the arc-shaped plate structure becomes a semi-cylindrical shape, and the first clamping portion 43 is equivalent to a half circle of the cylindrical structure. Of course, the arc shape of the first retaining portion 42 can also be an arc shape of a quarter circle, or an arc shape of a three-quarter circle. In this regard, the embodiment of the present application is not limited here.

[0067] In addition, in the embodiment of the present application, a hole for connecting the buckle 100 can be provided on the first connecting portion 41, so that when the buckle 100 needs to be connected to the matching portion 40, the buckle 100 can be connected to the hole.

[0070] In addition, in some embodiments, the mating portion 40 includes a second connecting portion 44, a second retaining portion 45 and a second clamping portion 46; the second connecting portion 44 is connected to the second retaining portion 45, the second retaining portion 45 is a tubular structure, the second clamping portion 46 is arranged on the second retaining portion 45, and the second clamping portion 46 extends along the circumferential direction of the second retaining portion 45, and the second clamping portion 46 surrounds the second retaining portion 45; a second connecting hole is provided on the safety valve seat 30, a second clamping groove 302 is provided on the hole wall of the second connecting hole, and the second clamping groove 302 extends along the circumferential direction of the connecting hole, and the second clamping groove 302 surrounds the hole wall of the second connecting hole; the second retaining portion 45 is at least partially located in the second connecting hole, and the second clamping portion 46 is located in the second clamping groove 302.

[0071] By such a configuration, when the matching part 40 needs to be connected to the safety valve seat 30, the second retaining part 45 can be directly extended at least partially into the second connecting hole, and the second clamping part 46 is located in the second clamping groove 302, so that the second clamping part 46 is equivalent to being limited in the second clamping groove 302, so that when the user wears the breathing mask and the matching part 40 is subjected to force, at this time, the second retaining part 45 is equivalent to a lever, so that the second clamping part 46 will move, and the second clamping groove 302 will hinder the movement of the second clamping part 46, so that the second clamping groove 302 can ensure that the second clamping part 46 is located in the second clamping groove 302, ensuring that the user can wear the breathing mask. When the matching part 40 needs to be separated from the safety valve seat 30, the second clamping part 46 can be detached from the second clamping groove 302, and then the second retaining part 45 is taken out of the second connecting hole to complete the separation of the matching part 40 and the safety valve seat 30. In addition, by setting the second retaining portion 45 as a cylindrical structure and the second clamping portion 46 being arranged on the second retaining portion 45, once the second clamping portion 46 is located in the second clamping groove 302, the second retaining portion 45 can be prevented from being easily detached from the second connecting hole, so that the matching portion 40 is more firmly connected to the safety valve seat 30.

[0072] It should be noted that the second clamping portion 46 can be formed of an elastic material, for example, the second clamping portion 46 is formed of silicone, rubber and other materials.
