  • Publication number: 20210395879
    Abstract: A coated member, an electronic device, and a method for manufacturing the coated member are provided. The coated member comprises a substrate, a color layer formed on a surface of the substrate, and an interference layer formed on a surface of the color layer. A coordinate L* corresponding to a color space presented by the color layer in a CIE LAB color system is within a preset range. When the coordinates of L* are within the preset range, the color of the coated member may be the same or may be different from the color of the color layer. Light passes through the interference layer and then enters the color layer. The color layer reflects and refracts the light. The reflected light enters the interference layer. The interference layer interferes with the reflected light, so that the coated member appears to be a target color.

    Abstract: The present disclosure provides an electric toothbrush including a driving module, a connection shaft, a battery supporter, a support cover, a print circuit board and a switch. The driving module includes a driving element, a driving element supporter, a reset elastic element and a stress element. The connection shaft passes through the driving element supporter and the battery supporter. The driving element is used to drive the driving module to rotate from a starting position to a triggering position and make the reset elastic element generate elastic deformation. In the starting position, the driving element supporter is separated from the switch, and the switch is in an OFF state. In the triggering position, the driving element supporter contacts the switch and the switch is in an ON state, and the driving module rotates to the starting position with a reset force of the elastic deformation of the elastic element.
