Description

Antifog lens structure reaches goggles including it

Technical Field

The utility model relates to a goggles technical field especially relates to an antifog lens structure and include its goggles.

Background

Goggles and sports-type goggles play a role of preventing eyes from being damaged by foreign substances on a physical level in addition to functions of filtering ultraviolet rays and preventing wind. The goggles fog is a difficult problem which always troubles the goggles user, especially the goggles for ice and snow sports, and the situation of the fog of the skiing goggles is particularly serious because the temperature difference between the external environment and the vapor breathed by the human body and the heat emitted by the human body is large.

The structure commonly used in the market at present is a double-layer lens structure, which consists of a PC lens, a lens bracket and an antifogging lens. This structure can form an air thermal insulation chamber between PC lens and antifog lens, effectively reduces the antifog lens that is close to the face and the difference in temperature of the inside air of snow glass and aqueous vapor, reduces the probability that the fog or lens freeze.

In view of the fact that goggles, particularly goggles for ice and snow, need to be used under the condition of pressure changes such as mountaineering and mountaineering, the heat insulation cavity needs to be provided with a certain exhaust mechanism for balancing the pressure difference between the air heat insulation cavity and the outside so as to avoid the influence of lens bulges on vision. The associated venting mechanism is such that the humidity of the air within the air insulating chamber will vary depending on the external environment in which it is located. The air in the thermal insulation cavity is heated in the use process of the goggles, and moisture in the thermal insulation cavity is possibly condensed on the inner side surface of the PC lens due to temperature difference, so that the fogging phenomenon in the thermal insulation cavity is caused.

One way to avoid fogging in the insulating chamber is to add an anti-fogging treatment to the inner surface of the PC lens (e.g., by applying an anti-fogging coating to the inner surface of the PC lens). However, after the inner side surface of the PC lens is subjected to antifogging treatment, the surface cannot be subjected to strengthening treatment (such as soaking in strengthening liquid), so that potential safety hazards exist in the PC lens.
