Automatic classification dustbin based on capacitive sensor principle

Abstract

The invention relates to an automatic classification dustbin based on a capacitive sensor principle. The automatic classification dustbin comprises a detection device; the detection device comprises a slide way, a tail end of the slide way is not closed, and a beginning end is fixed with a baffle plate; a push device used for pushing matters on the slide way to move forward is installed on the baffle plate; N capacitive proximity switch sensors are arranged successively along a slide way direction at a lower slide way edge from one side closer to the baffle plate; distances between the N capacitive proximity switch sensors and the lower slide way edge are increased successively; according to the capacitive sensor principle, capacitive proximity switch sensor induction distances are different if dielectric constants are different; detection distances of domestic wastes such as metal, cell, glass, plastic and paper, and the like are decreased successively; and a classification device is driven to turn around by a stepping motor, thereby waste classification is completed. According to the invention, a waste classification scheme with a simple classification mode, multiple classification types, a simple structure, no noise and an energy-saving way is provided, and the scheme assists in solving a problem that a device volume is huge in the prior art.

Description

technical field [0001] The invention relates to an automatic sorting garbage bin based on the principle of a capacitive sensor, belonging to the technical field of electromechanical integration. Background technique [0002] The garbage cans in daily life are simple in structure, relying entirely on people's consciousness to realize garbage classification, and the amount of garbage recycling is very small, which cannot reach the expected garbage recycling efficiency. Although reusable garbage is also being recycled, it depends on people's repeated operations, which is inefficient and inconvenient. There are several designs of automatic garbage sorting devices in the prior art, such as the relevant design of Tsinghua University in China. The general working procedure is: throw in garbage; metal detectors detect whether it is metal, and the classification execution module works, and the first step of classification is completed; The compression module works, the travel switch...

AI Technical Summary

Problems solved by technology

It can be seen from this that the classification process of this design of Tsinghua University is very complicated, and the device is relatively large. It is impossible to install such a large trash can in the home and campus, and there is no need for such a complicated classification device. At the same time, The above-mentioned garbage sorting method will cause noise and form secondary pollution, so it is not conducive to popularization and application in daily life

The trash can disclosed in the utility model patent with application number 201020661576.X can only classify iron trash, and its function is too single to complete the garbage sorting work well.
