AI Technical Summary

Technical Problem

Existing oral scanner protective covers cannot adjust the tilt angle of the lens, affecting the scanning imaging results, and the lens surface is prone to attracting dust and foreign objects.

Method used

A protective sleeve for an oral scanner, including a lens adjustment mechanism and a protective clip, was designed. The lens adjustment mechanism consists of a concave silicone pad, a sponge pad, a flat silicone pad, and an adjustment knob, which allows adjustment of the lens tilt angle. The protective clip seals the rectangular through hole through the clip body, a rounded corner rocker, and a sealing gasket to prevent dust and foreign objects from sticking.

Benefits of technology

It enables adjustable lens angles, reduces refractive errors, improves image quality, effectively prevents lens surface contamination, and ensures scanning accuracy.

Abstract

This utility model discloses a protective cover for an oral scanner, including a main body. A rectangular through-hole is formed on the front surface of the main body near the upper end. A semi-circular groove is formed on the side of the main body. A circular through-hole is formed inside the rectangular through-hole. A lens adjustment mechanism is movably installed inside the rectangular through-hole. A slot is formed on the front surface of the main body near the lower end of the rectangular through-hole. This protective cover for an oral scanner, through the lens adjustment mechanism, allows the operator to adjust the tilt angle of the protective lens as needed and clamp it in place. This effectively reduces refraction errors, improves image quality, ensures accurate measurement by the oral scanner, and reduces the influence of the protective lens on the final scanning image result. The protective clip can be fitted and clamped onto the upper end of the oral scanner protective cover, making assembly and disassembly simple. It also seals the rectangular through-hole, preventing dust and foreign objects from adhering to the surface of the protective lens before use.
