Abstract
Description
Technical Field
[0001] The utility model relates to an optical lens, in particular to a group of anti-fog and oil-proof optical lenses. Background Art
[0002] An optical lens is a specially designed and manufactured transparent medium component, usually used to adjust, guide or change the propagation path of light to achieve specific optical functions. Its main function is to refract light to form real or virtual images. These lenses are usually made of optical glass or optical plastic, with different refractive indices and curvature radii, so as to achieve specific imaging effects in various optical devices. They are widely used in many fields, including but not limited to glasses, camera lenses, microscopes, telescopes, projectors, laser systems and various other optical instruments. Depending on the material, design and purpose, optical lenses can have various types and functions.
[0003] Nowadays, optical lenses are used in many scenarios and require different performances. Ordinary optical lenses are difficult to use in many harsh environments, such as low temperature and high humidity, and frequent oil stains. Traditional optical lenses are prone to fogging and oil stains, which seriously affect visual clarity and user experience. Utility Model Content
[0004] The utility model aims to solve the problem that the existing optical lenses will fog up under low temperature and high humidity conditions and the optical lenses will become blurred under oily environments.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A group of anti-fog and oil-proof optical lenses, including a lens substrate, a partition layer is attached to the entire surface of the lens substrate, a frame is arranged on the side of the lens substrate, an anti-fog layer is arranged on the surface of the partition layer, a heating layer is arranged at a position where the inner wall of the frame is staggered from the lens substrate, the heating layer is attached to the surface of the lens substrate, an oleophobic layer is arranged on the surface of the anti-fog layer and the heating layer, and a control module is arranged on the top of the frame.
[0007] Preferably, the control module comprises a small battery and a microprocessor, and the small battery is arranged on one side of the microprocessor.
[0008] Preferably: a thin heating wire is further arranged on the inner side of the heating layer, and the thin heating wire is attached to the surface of the oleophobic layer on the lens substrate.
[0009] Preferably, the heating layer is a micro heating film.
[0010] Preferably, the heating layer is annular in design and is offset from the position of the lens substrate where the line of sight is directed.
[0011] Preferably, the isolation layer is a transparent insulating layer.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] By setting the anti-fog layer, the oleophobic layer and the heating layer, the anti-fog layer is used to achieve the anti-fog purpose in the first step when the heating layer is not turned on, so as to prevent a large amount of fog from adhering to the surface of the lens substrate, and then the heating layer starts heating to quickly remove the fog on the surface of the lens substrate to maintain a clear line of sight. The oleophobic layer improves the ability to gather oil and isolates the oil from the lens substrate to facilitate cleaning, and the surface of the oleophobic layer also has a dust removal effect, achieving the effect of heating the lens substrate to prevent fogging and preventing oil through the oleophobic layer, solving the problem that the existing optical lenses will fog under low temperature and high humidity conditions and cause the optical lenses to become blurred in an oily environment.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] See also Figures 1 to 3 In an embodiment of the utility model, a group of anti-fog and oil-proof optical lenses includes a lens substrate 1, and a partition layer 2 is attached to the entire surface of the lens substrate 1. The partition layer 2 is a transparent insulating layer, which is used to improve the insulation effect of the lens substrate 1 to avoid short circuit cleaning of the micro-heating film during use. A frame 3 is arranged on the side of the lens substrate 1, and an anti-fog layer 4 is arranged on the surface of the partition layer 2. The anti-fog layer 4 is a nano anti-fog coating that initially provides an anti-fog effect to avoid a large amount of fog directly adhering to the surface of the lens substrate 1 and causing blurry direct view of the lens substrate 1, and then the final defogging effect is achieved through the use of the heating layer 5.
[0020] A heating layer 5 is provided at a position where the inner wall of the frame 3 is offset from the lens substrate 1. The heating layer 5 is annular in design and is offset from a position on the lens substrate 1 where the line of sight is directly viewed. This design is to avoid interfering with the optical properties of the lens substrate 1, such as causing scattering or distortion of the lens substrate 1. The heating layer 5 is a micro-heating film, which is very thin and has stable heating characteristics. The temperature generated by the micro-heating film does not affect the inherent characteristics of the lens substrate 1, and can also increase the temperature of the lens substrate 1 after heating, thereby making it difficult for water mist to adhere to the surface of the lens substrate 1 through temperature, thereby achieving a defogging effect. The heating layer 5 is attached to the surface of the lens substrate 1, and an oleophobic layer 6 is provided on the surface of the anti-fog layer 4 and the heating layer 5. The oleophobic layer 6 is a fluorine-containing polymer material, which is an existing material and will not be described here. The oleophobic layer 6 has a low surface tension, and oil droplets will automatically gather into spheres when they contact the surface, which is very easy to clean.
[0021] The inner side of the heating layer 5 is also provided with a thin heating wire 11, which is attached to the surface of the oleophobic layer 6 on the lens substrate 1. The arrangement position of the thin heating wire 11 is as follows: Figure 1 As shown, such a distribution extension can make the heating area wider without affecting the line of sight on the lens substrate 1, thereby achieving a wider heating coverage effect. The role of the filaments is to extend the heating area, and the filaments will be ignored when close to the line of sight, so as not to affect the direct vision effect.
[0022] The top of the frame 3 is provided with a control module 7, which is connected to the heating layer 5 through a wire, and a thin heating wire 11 is connected to the heating layer 5. Figure 1 As shown, the control module 7 includes a small battery 8 and a microprocessor 9. The small battery 8 is arranged on one side of the microprocessor 9. The microprocessor 9 has a built-in working time. Generally, the heating time is 5 minutes. Such a heating time can effectively defog and play a protective role. A knob adjuster 10 is arranged on the microprocessor 9 for manually adjusting the heating stability of the heating layer 5. The highest setting temperature of the heating layer 5 is 30 degrees, so as to avoid excessive temperature and affect the lens substrate 1.
