smart defogging glasses

Abstract

The invention aims at providing a pair of smart demisting glasses, comprising a left side hollow glasses frame, a right side hollow glasses frame, a left side hollow glasses leg, a right side hollow glasses leg, a left side hollow glasses bridge of nose and a right side hollow glasses bridge of nose, wherein a seal membrane is arranged between the left side hollow glasses frame and the right side hollow glasses frame; the seal membrane is internally provided with a small rechargeable battery and an overcharge prevention device; two heating devices are respectively installed at the inner sides of the left side hollow glasses bridge of nose and the right side hollow glasses bridge of nose; two temperature difference power generation pieces are respectively installed at the inner sides of the left side hollow glasses leg and the right side hollow glasses leg; the left side hollow glasses leg or the right side hollow glasses leg is internally provided with a minitype temperature control chip; the left side hollow glasses frame, the right side hollow glasses frame, the left side hollow glasses bridge of nose and the right side hollow glasses bridge of nose are respectively filled with heat conduction liquid; the small rechargeable battery, the heating devices, the overcharge prevention device, the minitype temperature control chip and the temperature difference power generation pieces are respectively connected by a lead. The smart demisting glasses are simple in structure and easy to maintain.

Description

technical field [0001] The invention relates to glasses, in particular to defogging glasses. Background technique [0002] When people go out of the air-conditioned room in summer, and when people walk into a warm room from outside in winter, the lens of the glasses will become blurred due to the large temperature difference between indoor and outdoor, and the water vapor will liquefy, and people have to wipe the lens frequently. , which caused a lot of distress to people. [0003] At present, there are five main methods of "defogging" glasses: using special material lenses, lens coating, spraying chemicals on the lenses, adding mechanical erasing devices to glasses, and built-in electric heating devices. The first method is very convenient, but the cost is high, the production of materials is more difficult, and it is not easy to be accepted by the public. The second method is more convenient, but the price is more expensive, and when the coating is damaged, it is difficu...

AI Technical Summary

Problems solved by technology

The first method is very convenient, but the cost is high, the production of materials is more difficult, and it is not easy to be accepted by the public

The second method is more convenient, but the price is more expensive, and when the coating is damaged, it is difficult to repair, only the entire lens and its anti-fog film can be replaced

The third method is not very convenient, people need to carry the spray with them, and its chemical substances may be harmful to the human body

The fourth method is more convenient, but the mechanical device will increase the quality of the glasses, and the complex mechanical structure is easily damaged and difficult to maintain. Wiping the glasses through the mechanical structure may easily damage the lens and fail to achieve the desired effect

The fifth method is more popular in the market, but most electric heaters cannot be intelligent, some have complex structures, and the devices are cumbersome, some need to be turned on manually, and some devices produce fog when the temperature difference between the lens and the environment is not enough The heating circuit is also running at times, which reduces the service life of the equipment. Some devices have built-in batteries that need to be removed and replaced frequently, which is very troublesome.

[0004] Most glasses that use a built-in electric heating device to defog, the built-in battery installed is relatively large, which will increase the quality of the glasses, and most of them are disposable, which is troublesome to disassemble and pollutes the environment

[0005] Most glasses that use a built-in electric heating device to defog, heat the heating wire to increase the temperature of the lens, but the slender heating wire is easy to damage and break, and it is easy to cause uneven heating of the lens when heating

Poor temperature control of the heating wire may cause damage to the frame lenses
