Barrel lid slow descending device, intelligent garbage can and control method thereof

Abstract

The invention provides a barrel lid slow descending device which comprises a mechanical control portion and an electrical control portion. The mechanical control portion comprises a speed reduction box, a barrel lid rotationally connected with the speed reduction box, and a torsional spring installed between the speed reduction box and the barrel lid. The barrel lid is provided with a rotating corner connector, and the rotating corner connector comprises a rotating end rotationally connected with the speed reduction box and a corner connector end fixedly connected with the barrel lid; the torsional spring is provided with a first torsional arm and a second torsional arm, the rotating center of the torsional spring is coaxially with a transmission output shaft of the speed reduction box, the first torsional arm is limited by the speed reduction box, and the second torsional arm is limited by the barrel lid; the electric control portion comprises a motor in transmission connection with the barrel lid and a main control device for controlling the motor to rotate forwards and reversely and achieve brake. The invention further provides an intelligent garbage can provided with the barrellid slow descending device and a control method thereof. The mechanical control and the electrical control over opening or closing are perfectly combined, rapid opening of the barrel lid can be achieved, the size of a mechanical portion can be lowered, the circuit structure can be simplified, and the cost is lowered remarkably.

Description

technical field [0001] The invention belongs to the technical field of intelligent garbage cans, and in particular relates to a slow-falling device for a lid, an intelligent garbage can and a control method thereof. Background technique [0002] Most trash cans have a cover to prevent the smell of garbage from spreading. There are generally uncovered trash cans and foot-operated trash cans. The uncovered trash can generally requires the user to lift the lid; Step on the pedal, drive the connecting rod in the middle, and push the lid to open. But above-mentioned two kinds all can only rely on bung lid self gravity to fall when bung falls, and falling speed is fast, easily causes bung to break. Therefore, in order to make the lid of the trash can fall slowly and prevent the lid from breaking easily when it lands, many smart trash cans have been derived on the market. [0003] At present, the slow lowering of the lid of the smart trash can on the market is realized by a dampi...
