Abstract

This invention provides an intelligent energy-saving socket, relating to the field of intelligent socket technology. The intelligent energy-saving socket includes a housing with several five-hole sockets on its top. An adjustment groove is located in front of the sockets on the top of the housing, and a rotation limiting component is installed inside the adjustment groove. In use, rotating the knob produces a clicking sound under the action of a ratchet and pawl. A torsion spring inside the housing absorbs elastic potential energy, and the helical gear, along with the rotation of the ratchet, drives the helical rack and sealing plate backward, thereby separating the sealing block from the socket and opening the socket. When not in use, releasing the pawl releases the torsion spring's elastic force, causing the helical gear to rotate in the opposite direction, moving the sealing plate forward. The sealing block then seals the socket, closing it and preventing external debris from entering the socket and causing circuit board malfunctions, electrode corrosion, or socket blockage.
