Abstract
Description
Technical Field
[0001] The utility model relates to a lens, in particular to a lens with a self-cleaning effect. Background Art
[0002] A lens is a transparent light-transmitting part, usually made of glass or resin. It is usually used in various optical instruments, such as camera lenses, microscopes, telescopes, etc. It is generally made through the steps of melting, mixing, molding, cooling and solidification, and grinding and polishing, and has the function of converging or dispersing light.
[0003] Existing lenses encounter many scenarios in daily use. For example, lenses used as glasses are very easy to adhere to dust and water droplets in daily use. Lenses used in cameras are contaminated with dust when used outdoors, which will particularly affect the quality of photos. These are all caused by the insufficient anti-fouling ability of the lenses. Therefore, it is necessary to design a lens with strong anti-fouling ability to solve the above problems. Utility Model Content
[0004] The utility model aims to solve the problem that the existing lenses have insufficient anti-fouling ability and thus affect the use.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A lens with self-cleaning effect comprises a lens body, the surface of which is provided with a number greater than one of small cylinders arranged vertically and horizontally, and an anti-fouling composite layer is attached to the surface of the lens body and the small cylinder area of the lens body.
[0007] Preferably, the anti-fouling composite layer comprises an anti-static layer, the anti-static layer is attached to the surface of the lens body, and a hydrophobic and oleophobic layer is attached to the surface of the anti-static layer.
[0008] Preferably, the small cylinders are nano cylinders, the number of the small cylinders is greater than one, and the small cylinders are arranged vertically and horizontally on the surface of the lens body.
[0009] Preferably, a dirt-draining groove is provided on the surface of the lens body at a position close to the outer side and staggered from the small cylinder, and the anti-fouling composite layer is attached to the surface of the dirt-draining groove.
[0010] Preferably, the number of the dirt-draining grooves is several, and the several dirt-draining grooves are arranged in parallel at positions where the lens surface is staggered from the small cylinder.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] By setting up an anti-fouling composite layer and small cylinders, the surface may still appear smooth from a macroscopic perspective, but under a microscope, these fine columnar structures are clearly visible, like a miniature forest. Each column can reduce the contact area between the liquid and the solid surface and promote the rolling and shedding of the liquid. The anti-static layer in the anti-fouling composite layer can prevent dust from adhering to the surface of the lens body due to static electricity. The waterproof and oleophobic layer mainly forms an ultra-thin coating on the lens surface. This coating can significantly reduce the adhesion of water and oily substances to the lens surface, making it difficult for liquid to stay on the surface, thereby reducing the accumulation of stains, achieving the effect of self-cleaning of the lens surface and not easy to adhere to stains, and solving the problem of insufficient anti-fouling ability of existing lenses affecting their use.

[0016] 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.
[0017] See also Figures 1-2 , in the embodiment of the utility model, a lens with a self-cleaning cleaning effect;
[0018] Example 1
[0019] The lens body 1 includes a lens body 1, wherein the surface of the lens body 1 is provided with a number of small cylinders 2 arranged vertically and horizontally greater than one, and the small cylinders 2 are nano cylinders, wherein the number of small cylinders 2 is greater than one, and the small cylinders 2 are arranged vertically and horizontally on the surface of the lens body 1 to form an antifouling structure, and the nano small cylinders 2 are designed to cooperate with the hydrophobic and oleophobic layer 5 to make the surface energy of the material very low, and the surface energy can be calculated by the fixed material surface energy formula, that is, when discussing the surface energy of solid materials, a commonly used formula is to calculate the energy required to create a surface from a bulk material, if it is known that the energy of the unoptimized and optimized (i.e., with a surface) ultra-thin layer (slab) model is Eslab and Ebulk respectively, Eslab refers to the total energy of the surface slab model. This is a model constructed in the calculation, which is used to simulate a thin layer of material, usually including the thickness of several atomic layers and the surfaces on both sides. This model is used to study the properties of the material surface, including surface reconstruction, adsorption, surface energy, etc. The energy change of the system caused by the presence of the surface will be considered in the calculation, and Ebulk represents the energy of a single atom or a unit (such as a unit cell) in the bulk phase. This refers to the energy inside an ideal, infinite material without surface effects. When calculating the surface energy, it is used as a reference point to deduct the portion contributed by the volume, thereby evaluating the additional energy of the surface alone. If the number of atoms contained in the slab is n, the surface energy γ can be estimated by the following formula: γ = (Eslab
[0020] -nEbulk) / 2A, where A is the surface area of the slab. This formula takes into account the energy increase brought about by dividing a bulk material into two surfaces, and is divided by 2 because there are two surfaces. The structure composed of small cylinders 2 further hinders liquid and solid stains from adhering to the surface of the lens body 1. Between the tiny structures composed of small cylinders 2, air can be trapped under the structure to form a kind of "air cushion", which helps to reduce moisture and stain deposition. A dirt drainage groove 6 is provided on the surface of the lens body 1 near the outer side and staggered with the small cylinders 2. The anti-fouling composite layer 3 is attached to the surface of the dirt drainage groove 6. There are several dirt drainage grooves 6, and several dirt drainage grooves 6 are opened in parallel on the lens surface at a position staggered with the small cylinders 2. When the lens body 1 is installed, the dirt drainage groove 6 needs to be perpendicular to the ground and follow the direction of gravity, so that the stains can flow out of the lens body 1 along the dirt drainage groove 6.
[0021] Example 2
[0022] The surface of the lens body 1 and the small cylinder 2 area of the lens body 1 are both adhered with an anti-fouling composite layer 3, and the anti-fouling composite layer 3 includes an anti-static layer 4 to reduce the electrostatic adsorption effect and prevent dust and other particles from adhering to the lens due to static electricity. The anti-static layer 4 is adhered to the surface of the lens body 1, and the surface of the anti-static layer 4 is adhered with a hydrophobic and oleophobic layer 5. The coating can significantly reduce the adhesion of water and oily substances to the lens surface, making it difficult for liquid to stay on the surface, thereby reducing the accumulation of stains.
[0023] In summary, the design of the anti-fouling composite layer 3 , the small cylinder 2 and the dirt-discharging groove 6 enables the lens body 1 to achieve a self-cleaning effect, so that stains are not easily attached to the surface of the lens body 1 .
