Automatic toothpaste dispensing device for due tooth care comprises device holder, which can be divided into a control box, and a toothpaste rack. There are installed a camera, display and a control panel respectively in central, upper and lower part of the said control box. Said toothpaste rack with several toothpaste drums fixed thereon is located to the right side of the control box. Said toothpaste drums include housings, and in the middle of the inner wall of the housings are mounted fixing brackets. On the fixing brackets are installed toothpaste extrusion pumps, above them are toothpaste entrances, and below them toothpaste exits. Below the fixing brackets are installed toothbrush hangers, and on the bottom of inner cavity of the toothbrush hangers squeezing buttons are fixed. The present invention analyzes the teeth images, estimates teeth conditions, and subsequently obtains an appropriate tooth care plan with the processor.

Disclosed is a high-frequency-tuning sliding electrical contact. The contact includes a tuning ring which is composed of an inner elastic piece, an upper base, an outer elastic piece and a lower base. Pull rods are welded to an upper side face of the upper base, and upper ends of the pull rods are driven to move up and down by a motor, so that the tuning ring slides up and down between the outer sleeve and the inner sleeve along the pull rods. The overall structure of the novel electrical contact is simple, compact and economical. The disclosure reduces joule heat produced by contact resistance and prevents contact surface fusion welding or conductive damage, and is especially suitable for tuning in a small gap range.
