Description

Glasses structure

Technical Field

The present invention relates to a glasses structure, and more particularly, to a glasses structure capable of preventing external dust from flying into the eyes and having the efficacy of ventilation and anti-fog.

Background

Most of the spectacle lenses sold on the market at present have no anti-fogging design, and once the temperature change of the surrounding environment is large, the spectacle lenses are easy to fog, which causes the vision of the user of the spectacles to be fuzzy, and if the spectacle lenses fog when driving, moving or needing good vision, the user is possibly in a dangerous situation, therefore, how to prevent the spectacle lenses from fogging is a very important subject at present.

Generally, the protection measures of the glasses on the market mainly achieve the anti-fog effect by performing anti-fog treatment on the embedded functional lenses in advance or spraying waterproof spray on the lenses, however, the waterproof spray effect is very short, and the waterproof spray needs to be frequently sprayed on the lenses to achieve the continuous anti-fog effect, so that the use is very inconvenient; moreover, the water-proof spray is mainly composed of surfactant and other chemical agents, and the direct spraying on the lens or the frame may also cause damage to the glasses.

In addition, there is a multi-piece defogging technology, the existing antifog lens set includes two spaced lenses, and the two spaced lenses are difficult to conduct heat, so that the lens located at the inner side is not fogged due to the temperature difference junction between the human body and the outside. Although the existing antifogging lens group has an antifogging effect, the antifogging lens group is heavy and burdens a user due to the fact that a double-layer lens structure is used.

Accordingly, the industry has developed taiwan patent publication No. I626489, "defogging glasses", which includes: the lens holder comprises a body, a lens and a lens, wherein the body is provided with a frame part, at least one foot stand and at least one lens, the at least one foot stand is connected with the frame part, the frame part further comprises at least one accommodating part and a plurality of air outlet holes, the at least one accommodating part is used for accommodating the at least one lens, and the plurality of air outlet holes are arranged on the periphery of the at least one accommodating part; a gas pump embedded in the body, wherein the gas pump is a piezoelectric actuating gas pump; a switching element; a control module electrically connected to the switch element and the gas pump; and a gas channel embedded in the body and communicated between the plurality of gas outlets and the gas pump; the control module enables the gas pump according to the enabling signal, so that the gas is ejected from the plurality of gas outlets through the gas channel, and the ejected gas demists the at least one lens.

The above-mentioned structure is inflated by a set of gas pumps mounted on the glasses body and is ventilated by the gas outlet, and the structure mounted on the glasses is not only heavy in weight, but also relatively high in cost and price, and the gas pumps are not easy to maintain when damaged.

Therefore, designers, with the abundant design, development and practical manufacturing experience of the related industry for many years, provide a glasses structure by researching and improving the existing technical means, so as to achieve the purpose of better practical value.
