Mask sealing face frame

Abstract

A mask sealing face frame comprises a frame sleeve, a supporting frame and a hanging rope. The sealing face frame is characterized in that the frame sleeve comprises an upper frame, a side frame, a middle frame and a lower frame; the upper frame is positioned above the nose bridge and at the lower eyelid; the two ends of the frame sleeve are connected with the side frame, the side frame is locatedon the two sides of the cheek, the upper side and the lower side of the side frame are connected with the upper frame and the lower frame respectively, the middle frame is located between the mouth and the nose, the two ends of the middle frame are connected with the side frame, the lower frame is located at the jaw and supports the jaw, and the two ends of the lower frame are connected with theside frame; the upper frame, the side frame, the middle frame and the lower frame are fixedly connected or separately connected to form a frame sleeve; the hanging rope is connected with the frame sleeve; the earphone is hung behind ears or brains; the shape of the frame sleeve is matched and coincided with the shape of the facial skin, the frame sleeve is pressed on the periphery of the mask, theperiphery of the mask is in close contact with the facial skin under the tensioning effect of the hanging rope, and air leakage is prevented; the supporting frame is placed on the mouth and nose portion of the face to support the mask fabric, a ventilation space is formed in the mouth and nose portion of the face, the upper frame of the frame sleeve comprises an outer wrapping layer and a framework, the outer wrapping layer wraps the periphery of the framework, the frame, the middle frame, the lower frame and the outer wrapping layer are made of elastic materials, and the framework and the supporting frame are made of plastic or metal materials. Due to the fact that durable materials are adopted, the frame sleeve and the supporting frame can be repeatedly used, and consumables are saved.

Description

technical field [0001] The invention belongs to the field of health protection, and in particular relates to a mask sealing surface frame of a sealing mask. Background technique [0002] Existing masks are made of soft fabrics. Due to the unevenness of the human face, the fit between the mask and the facial skin is not tight. Even if a metal wire is installed on the bridge of the nose, air leakage is still around the mask, and the protective performance is reduced. In the mouth and nose of the face, the ventilation space is small, the breathing is not smooth, and there is a feeling of suffocation. Contents of the invention [0003] The object of the present invention is to provide a mask sealing surface frame, which is worn on the face of the human body and pressed on the mask so that the periphery of the mask is in close contact with the skin of the face to prevent air leakage, thereby improving the protective performance of the mask. The contact between the mouth and no...
