AI Technical Summary
When using existing dental imaging equipment, the temperature difference between the reflector and the inside of the oral cavity causes the reflector to fog up rapidly, affecting the clarity of the captured images.
The design employs a combination of a heating block and an elastic balloon. A sensor detects moisture and activates the heating block to dry the moisture on the reflector surface. At the same time, the elastic balloon blows air through a filter plate and onto the reflector surface. Combined with the support rod, it maintains the optimal opening of the reflector cavity and adjusts the reflector angle, thus solving the problem of reflector fogging.
It enables rapid evaporation of moisture on the reflector surface, ensuring the clarity of the captured images, and reduces patient discomfort through angle adjustment and oral retention devices, providing a clear display of the dental arch.
