[0002] A breathing mask is a protective device used to cover the mouth and nose, mainly for filtering harmful substances in the air (such as bacteria, viruses, dust, etc.) or providing clean gas (such as oxygen). Breathing masks are widely used in medical, industrial, fire protection and daily life fields. For example, in the medical field, breathing masks are used to assist patients in breathing or prevent cross-infection; in the industrial field, breathing masks are used to protect workers from harmful gases or particulate matter. The core function of a breathing mask is to closely fit with the face through a sealing ring to ensure that gas does not leak, thereby providing effective protection.

[0003] At present, most of the sealing rings for breathing masks on the market are made of a single material. Since the part of the sealing ring in contact with the face is usually hard, wearing it for a long time is likely to cause skin compression and discomfort, and there may also be allergic reactions, especially in sensitive areas such as the nose bridge and cheeks; in addition, the existing sealing rings for breathing masks only serve as a connection and seal between the breathing mask and the face, and the overall thickness of the sealing ring is small, making it unable to fit the facial contour of each person, easily resulting in air leakage and affecting the protection effect. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sealing ring for a breathing mask, so as to solve the problems of poor comfort, easy allergy and poor versatility during long-term wearing in the prior art.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1:

[0024] As per the instruction manual Figure 1-3 As shown, a sealing ring for a respirator includes a sealing ring body 1, which is snapped onto the edge of a respirator body 2. Multiple "U"-shaped protrusions 3 are provided on the bottom edge of the respirator body 2. The sealing ring body 1 is composed of an integrally formed connecting end 4, an extension piece 5, and a contact base 6. The connecting end 4 has a U-shaped structure that encloses the outer side of the multiple protrusions 3, and the connecting end 4 is located on the inner side of the U-shaped structure, matching the shape of the respirator body 2 and the multiple protrusions 3. The thickness of the extension piece 5 is less than or equal to the thickness of the respirator body 2. This allows the extension piece 5 to fit more tightly against the body part. The width of the contact base 6 is greater than the outer width of the connecting end 4, and the thickness of the contact base 6 is 1.5mm-2mm. Multiple flexible baffles 7 are provided on the side of the contact base 6 away from the extension piece 5. The number of multiple flexible baffles 7 is greater than or equal to four, and the multiple flexible baffles 7 are equidistantly arranged on one side of the contact base 6. The length of the multiple flexible baffles 7 is the same as the thickness of the contact base 6, and the thickness of the flexible baffles is 0.5mm. This allows one side of the contact base 6 to fit more tightly against the body part through the flexible baffles.

[0025] As per the instruction manual Figure 4As shown, an antibacterial layer 8 is coated on one side of the contact base 6 located among multiple flexible flaps 7. The antibacterial layer 8 is a nano silver ion antibacterial coating, which isolates the contact between the body and the sealing ring, destroys the cell structure of bacteria, inhibits their reproduction, and ensures hygienic performance.

[0026] When the present utility model is specifically implemented, the U-shaped connecting end 4 of the sealing ring body 1 is closely fitted with the "丰"-shaped card slot of the breathing mask body 2 to prevent gas leakage. At the same time, the extension piece 5, the contact base 6 and multiple flexible flaps 7 form a multiple sealing barrier by adapting to the facial curve through the deformation ability of high-elastic silica gel. At the same time, the nano silver ion antibacterial layer 8 coated on the contact base 6 and multiple flexible flaps 7 can isolate the contact between the body and the sealing ring, destroy the cell structure of bacteria, inhibit their reproduction, and ensure hygienic performance.

[0027] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the specific implementation manners is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
