Fully-sealed goggles

Abstract

The invention discloses fully-sealed goggles which comprise lenses, a lens frame for bearing the lenses, a sealing element hermetically attached to the face of a wearer, and a frame for connecting the lens frame and the sealing element,; the lenses are made of plastic; the lens frame is made of plastic or silicon rubber; the frame is made of silicon rubber; and the sealing element is made of silicon rubber; The plastic and the silicon rubber form the whole body of the goggles by means of bonding through heat vulcanization; one or more moisture permeable structures are seamlessly embedded in the frame; each moisture permeable structure is a dense silicone rubber film or a silicone rubber film without through holes with the hole diameter larger than 100 nm, and the thickness of each silicone rubber film ranges from 0.005 mm to 0.5 mm. The goggles do not contain vent holes through which liquid or solid particles can pass, but are provided with the moisture permeable structures, so that water vapor generated by eyes is discharged through the water vapor permeability of the silicone rubber films, and the goggles are well attached to the face of a person, so that the goggles are are fully-sealed goggles; The goggles have the advantages of preventing saliva from splashing, preventing dust, preventing water, preventing blood from passing, preventing germs and viruses from passing, preventing irritant gas from entering eyes, being capable of being repeatedly used after being sterilized and disinfected at high temperature and the like, and can be safely used in chemical workshops, hospitals and other occasions.

Description

technical field [0001] The invention belongs to the technical field of glasses, and relates to goggles, in particular but not exclusively to sports goggles such as health protection goggles and swimming goggles used in laboratories, workshops and hospitals. Background technique [0002] When carrying out chemical experiments in the laboratory, or when carrying out production in chemical and chemical workshops, it is often necessary to protect the eyes, and it is necessary to wear goggles or goggles. Since the parts of the current goggles or goggles are often assembled, there are more or less gaps between the parts, so that when the external conditions occur, the parts are prone to deformation, and the parts cannot be kept tightly connected. As a result, gaps are generated, and the gaps between the components become larger with time during use, so that harmful liquids or irritating gases can easily enter the eye mask and cause harm to the human body. [0003] When the doctor...

Problems solved by technology

The use of the sealing strip is a creative point of this patent document, but the use of the sealing strip leads to poor air permeability and cannot discharge the moisture in the goggles in time
