AI Technical Summary
The rotation gaps of traditional rotary knob screens can easily become channels for liquid intrusion, leading to corrosion of internal circuits, jamming of mechanical structures, and functional failure.
Waterproof components are used, including a first oil seal and a second oil seal, combined with O-rings and adhesive to form a multi-layer sealing structure that prevents liquid from entering the inside of the knob screen.
It effectively prevents liquid from entering the knob screen, ensuring smooth rotation, protecting circuit components and mechanical structures, and maintaining stable equipment operation.
