Abstract: An automatic opening-and-closing lid for a garbage bin includes a base member including an opening for a user throwing trash into the bin therefrom and first and second annular flanges. A lid is installed to the opening of the base member and is able to pivot with respect to the base member. A control is installed to the base member and includes a power source for power supply, a control panel, a driving member electrically connected to the control panel, a driven member and first and second sensor wires electrically connected to the power source. The first and second sensor wires are respectively disposed in the first and second annular flanges. A sensing region is formed proximal to the first and second sensor wires.

Abstract: A trash bin includes an automatic lifting upper lid and a barrel body. The barrel body includes a upper barrel and a lower barrel that are detachable. The upper barrel has an opening and a frame flange on the bottom that has one or more apertures. There is a latch member extended upwards from one lateral side of the aperture. The lower barrel has a coupling end on a upper side that has corresponding coupling members on two lateral sides and the front and rear sides. The trash bin can hold garbage as the ordinary one. The upper and lower barrels can also be separated so that the lower barrel can be held in the upper barrel with the upper lid covering the upper barrel. Thus the upper and lower barrels can be separated and stacked to facilitate packaging and transportation.

Abstract: A trash bin equipped with an automatic lifting lid includes a lid mounted onto a bucket. The lid has a base seat to hold batteries, a switch, a circuit board and an electronic component, a motor and a reducing gear box. The circuit board includes the electronic component and an induction controller which is extended to form an induction line located on the peripheral rim of the base seat. The reducing gear box is located on the rear end of the base seat and has a reducing gear set driven by the motor. One gear is extended above a trough located on the rear end of a shell to engage with another gear located at the rear end of an upper lid to transmit rotation and lift the upper lid. When energized by electricity, the induction line on the peripheral rim of the base seat may be induced to actuate automatic lifting of the upper lid to receive garbage.
