Slow descending device of dustbin cover, and intelligent dustbin and control method thereof

Abstract

The invention relates to the technical field of waste collection, and discloses a slow descending device of a dustbin cover. The slow descending device comprises a motor, a master control device and an angle sensing device; the motor is used for being in driving connection with the dustbin cover; the master control device controls forward and backward rotation and braking of the motor; the angle sensing device is used for sensing the rotation angle of the dustbin cover; and the angle sensing device is in communication connection with the master control device, when the dustbin cover is closedto a preset angle, the master control device controls the motor to brake so that the dustbin cover drives the motor to rotate to a closed position. In this way, slow descending of the intelligent dustbin cover is achieved, mechanical structure is reduced, the problems of metal fatigue and rust of a spring in a damping structure are avoided, meanwhile, the structure of the dustbin is more simple, and the size is smaller.

Description

technical field [0001] The invention relates to the technical field of garbage storage, and more specifically, to a slow-falling device for a garbage can lid, an intelligent garbage can and a control method thereof. Background technique [0002] Most trash cans have lids to prevent the smell of garbage from dispersing. Generally, there are uncovered trash cans and foot-operated trash cans. The uncovered trash cans generally require the user to lift the lid, but when the lid is lowered, only Rely on the gravity of the lid to fall; the pedal type trash can generally drives the connecting rod in the middle by stepping on the pedal, and pushes the lid to open. The cover is cracked. Therefore, how to make the lid of the trash can fall slowly, in order to prevent the problem that the lid is easy to break 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 through ...

[0002] Most trash cans have lids to prevent the smell of garbage from dispersing. Generally, there are uncovered trash cans and foot-operated trash cans. The uncovered trash cans generally require the user to lift the lid, but when the lid is lowered, only Rely on the gravity of the lid to fall; the pedal type trash can generally drives the connecting rod in the middle by stepping on the pedal, and pushes the lid to open. cover cracked

Therefore, how to make the lid of the trash can fall slowly, in order to prevent the problem that the lid is easy to break 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 through a damping mechanical structure. Generally, slow-down components, such as dampers, are installed in the trash can. These slow-down components will occupy a certain area of ​​the smart trash can. As a result, the space for the garbage can to hold garbage is reduced, and metal parts such as springs in the damping structure are prone to metal fatigue and rust problems. When these problems occur, the lid will not be easy to open or close, making the smart garbage can unusable.
