Technical Field
The utility model relates to a goggles technical field, in particular to goggles with defogging device.
Background
The existing goggles comprise various types such as open type goggles and closed type goggles, wherein the open type goggles are used in common work occasions; and closed goggles are needed in operations such as toxic aerosol, biochemical weapons, and unknown organisms in deep water in microbial infection environments and special environments.
After the existing closed goggles are worn, the lenses often generate fog under the conditions of high temperature and obvious temperature difference change, because the surfaces of the lenses contain saturated and supersaturated air at higher temperature and can not contain existing water vapor after being rapidly cooled, and the redundant water vapor is condensed into fine dew on the surfaces of the glasses due to the heterogeneous nucleation effect, so that light rays are subjected to diffuse reflection, and thus, the atomized opaque state is formed. And in a specific working environment, the protective glasses are not allowed to be taken down to wipe off the fog, and the condensation of the fog cannot be completely solved even by a chemical method. It is well known that new crown pneumonia (COVID-19) epidemic situation in early 2020, and the problem of fogging of goggles was reported many times in the news.
