Antifogging goggles

Abstract

The invention provides antifogging goggles. The antifogging goggles are characterized in that the antifogging goggles comprise a goggle lens with a hook face; an antifogging sheet is mounted onto theconcave hook face on the inner side of the goggle lens through a fixing structure, and comprises a base material layer and an antifogging layer; one side of the base material layer is coated with theantifogging layer; the antifogging layer is at least arranged on one, not opposite to the concave hook face when the base material layer is mounted onto the concave hook face, of the two sides of thebase material layer. The antifogging goggles have the advantages that one antifogging functional coating is added onto the inner layer of the goggles, and the antifogging objective of the antifoggingcoating is achieved through hydrophilia of its materials; mechanical ventilation or heating structures do not need to be added onto the goggles, so that the original simple structure of the goggles can be maintained, and safety is improved while cost is reduced.

Description

technical field [0001] The invention relates to the technical field of goggles, in particular to anti-fog goggles. Background technique [0002] It is known that when the temperature and relative humidity conditions in the space defined between the goggle body and the user's face and eyes have reached the dew point, and condensation similar to "fog" forms on the inner surface of the goggle, the goggle Eyepieces are clouded by moisture. Typically, this occurs when the cooler inner surface of the goggle lens has come into contact with a now warmer and wetter area enclosed within the goggle body. Since the dew point on the inside of the lens is affected by changing temperature, humidity, pressure and ventilation conditions, there are many possible conditions that can cause goggles to fog up. A common example of fogging occurs when a person who is skiing, biking, hiking, or engaging in other strenuous activity stops moving as fast as before, reducing the amount of airflow over...

AI Technical Summary

Problems solved by technology

Of course, this problem ranges from annoyance to the user to presenting a very dangerous situation where the user's field of vision has been greatly reduced while the user is traveling at high speed in a fixed obstacle objects such as trees, highly variable terrain such as bumps, cliffs, or other participants, or where the user otherwise has no clear view of intended targets or hostile opponents

Goggle fogging problem has resulted in injury and even death among goggle users

[0005] The methods for defogging goggles in the prior art generally include the following: increasing the passive air flow into the goggles, or sufficiently heating the inner surface of the goggle lens including removing the fog from the lens, but these require additional The mechanical structure is integrated into the goggles, the structure is cumbersome and increases the manufacturing cost
