Description

Sealing ring for breathing mask Technical Field The utility model belongs to the technical field of sealing rings, and particularly relates to a sealing ring for a breathing mask. Background Respiratory masks are protective devices for covering the mouth and nose, mainly for filtering harmful substances (such as bacteria, viruses, dust, etc.) in the air or for providing clean gases (such as oxygen). The breathing mask is widely applied to the fields of medical treatment, industry, fire protection, daily life and the like. For example, in the medical field, respiratory masks are used to assist patients in breathing or to prevent cross-infection, and in the industrial field, respiratory masks are used to protect workers from harmful gases or particulate matter. The core function of the breathing mask is to tightly attach the face through the sealing ring, so that gas is ensured not to leak, and effective protection is provided. In addition, the existing breathing mask sealing ring is only used for connecting and sealing the breathing mask and the face, and the overall thickness of the sealing ring is smaller, so that the sealing ring cannot be attached to the facial outline of each person, air leakage phenomenon is easy to occur, and the protection effect is affected. Disclosure of utility model The utility model aims to provide a sealing ring for a breathing mask, which solves the problems of poor wearing comfort, easy allergy and poor universality in the prior art. In order to solve the technical problems, the technical scheme provided by the utility model is that the sealing ring for the breathing mask comprises a sealing ring body, wherein the sealing ring body is clamped at the edge of the breathing mask body, a plurality of clamping blocks with a 'Feng' type structure protruding towards two sides are arranged at the bottom edge of the breathing mask body, the sealing ring body is composed of a connecting end, an extending piece and a contact base which are integrally arranged, the connecting end is in a U-shaped structure and is clamped at the outer sides of the clamping blocks, a plurality of flexible blocking pieces are arranged on one side, far away from the extending piece, of the contact base, and an antibacterial layer is coated on one side, located on the plurality of flexible blocking pieces, of the contact base. As a preferable technical scheme of the utility model, the sealing ring body is made of high-elasticity silica gel. As a preferable technical scheme of the utility model, the connecting end is positioned at the inner side of the U-shaped structure and is matched with the shapes of the breathing mask body and the clamping blocks. As a preferable technical scheme of the utility model, the thickness of the extension piece is smaller than or equal to that of the breathing mask body, so that the extension piece is tightly attached to the body part. As a preferable technical scheme of the utility model, the width of the contact base is larger than the width of the outer side of the connecting end, and the thickness of the contact base is 1.5mm-2mm. As a preferable technical scheme of the utility model, the number of the plurality of flexible baffle plates is greater than or equal to four, the plurality of flexible baffle plates are equidistantly arranged on one side of the contact base, the lengths of the plurality of flexible baffle plates are the same as the thickness of the contact base, and the thickness of the flexible baffle plates is 0.5mm, so that one side of the contact base is tightly attached to a body part through the flexible baffle plates. As a preferable technical scheme of the utility model, the antibacterial layer is a nano silver ion antibacterial coating for inhibiting bacteria from breeding. Compared with the prior art, the utility model has the advantages that: 1. The sealing ring is firmly connected with the breathing mask body through the matching of the 'Feng' -shaped clamping groove structure and the U-shaped connecting end, and meanwhile, the design of the extension piece, the contact base and the plurality of flexible baffle pieces of the high-elasticity silica gel material reduces the pressing sense of the face, so that the sealing ring is tightly attached to the face to prevent air leakage; 2. The nanometer silver ion antibacterial layer coated on the contact base can effectively isolate the skin from directly contacting with silica gel, can inhibit bacteria from breeding, and is suitable for long-time use.
