Description

Technical Field

[0001] This utility model relates to the technical field of optical lenses, specifically an adjustable optical lens. Background Technology

[0002] A lens is an optical element made of a transparent material with a surface that is part of a sphere. Lenses can be widely used in various fields such as security, automotive, digital cameras, lasers, and optical instruments. With the continuous development of the market, lens technology is becoming more and more widely used.

[0003] With the increasing application of lenses, they are also widely used in projection modules of household appliances such as washing machines, dishwashers, and refrigerators. By projecting the information on the appliance's display screen onto the ground, the information on the display screen can be observed intuitively. Most of the lenses on existing household appliance projection modules are lens groups composed of multiple lenses. Since the distance between the lens and the imaging point is inconsistent when the projection module is installed on different household appliances, the spacing distribution between the multiple lenses in the lens group is different. When producing lens groups, it is necessary to produce lens groups with different lens spacing distributions for different appliances, which increases the workload of lens group production.
