Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in FIGS. 1-3, an intelligent garbage can comprises:

the box 1, the inside below of box 1 is divided into two holding area through partition plate 101 with the inside below space of box 1, and the left holding area in this embodiment is nonmetal rubbish region 6, and the right holding area is metal rubbish region 7. The top of the box body 1 is provided with an opening, an opening and closing cover 2 is hinged to the opening, the opening and closing cover 2 is hinged to the opening of the box body 1 in an opening and closing mode, the end part of one side, hinged to the opening and closing cover 2, of the opening and closing cover is connected with a stepping motor, and the stepping motor is electrically connected with a main control system; human infrared sensor is installed to the opening part of box 1, human infrared sensor and master control system electric connection, when human infrared sensor detects human radiation and reaches certain intensity, send corresponding control command and convey to the master control system in, drive 2 upsets of opening and shutting by master control system control step motor again to realize the automatic switch action of opening and shutting lid 2.

A guide plate 3 is fixed on the inner wall of the box body 1 right below the opening of the box body 1, the guide plate 3 is of a downward inclined structure, a turnover baffle 5 is arranged at the lower end part of the guide plate 3, and the guide plate 3 is used for sliding an object falling from the opening onto the turnover baffle 5.

The overturning baffle 5 is arranged on the inner wall of the box body 1 right above the partition plate 101 through a rotating shaft, and the overturning baffle 5 is driven by a stepping motor to realize clockwise or anticlockwise rotation; the turnover baffle 5 is a turnover structure which is formed by welding two folded plates and has an angle of more than 90 degrees and less than 150 degrees, and when the turnover baffle 5 is in a static state, one of the folded plates and the tail end of the guide plate 3 are kept in a horizontal state; the turnover baffle 5 of the turnover structure can prevent garbage from directly sliding over the turnover baffle 5 due to inertia when sliding down from the guide plate 3 and directly dropping into a certain containing area, so that objects can stay on the turnover baffle 5 to play roles of identification and classification.

After the object slides down from the guide plate 3 to the flip board 5, the object is detected by the metal detector mounted on the inner surface of the flip board 5, that is, the metal detector is mounted on both the upper surface of the horizontal flap and the left surface of the vertical flap, so as to prevent the metal detector below the object from being unable to detect the object with excessive thickness, and therefore, the metal detector is also mounted on the side of the object. When the metal detector detects that the object dropping on the turnover baffle 5 has metal, the turnover baffle 5 is controlled to turn clockwise, the object is made to fall into the metal garbage area 7 on the right side, and if the metal detector detects that the object dropping on the turnover baffle 5 does not have metal, the turnover baffle 5 is controlled to rotate anticlockwise, and the object is made to fall into the non-metal garbage area 6 on the left side.

In order to reduce energy consumption, install photoelectric sensor directly over upset baffle 5, photoelectric sensor and master control system electric connection just when photoelectric sensor detects that there is the object on the upset baffle 5, just begin to detect the object on the upset baffle 5 through master control system control metal detector to avoid the long-time energy consumption loss that opens and cause of metal detector.
