Detailed ways

The following is a detailed description of the implementation of a solar energy environment-friendly dustbin of the present invention in conjunction with the accompanying drawings.

Referring to FIG. 1 , a solar energy-friendly dustbin includes a box body 11 and a cover body 12. The cover body 12 fits with the corresponding box body 11, that is, the size and size of the two are matched. The cover 12 includes a pressure sensitive plate 16 . The box body 11 includes an inner tank 111 with a volume of about 180 liters, which belongs to a medium-sized garbage bin.

In this embodiment, a pressure sensing board 16 and a solar panel 14 are arranged on the top of the cover 12 . A single-chip microcomputer 13 , a storage battery 15 , a motor 17 and a support rod 18 are arranged inside the cover body 12 .

A solar cell panel 14 is disposed on the outer surface of the pressure sensing panel 16 . The solar panel 14 is used to absorb light energy and generate electricity. Therefore, the solar energy-friendly dustbin in this embodiment is especially suitable for areas with better sunlight.

The pressure sensing board 16 includes a plurality of pressure sensors 161 (see FIG. 3 ). When a passer-by throws rubbish, when the rubbish touches the pressure-sensitive plate 16 of the dustbin, the pressure-sensitive plate 16 receives pressure from the outside, utilizes the pressure sensor 161 it contains to generate a signal, and transmits the signal to Microcontroller13.

Two or more support rods 18 are arranged inside the pressure sensing plate 16 , and a motor 17 is connected to one end of each support rod 18 . The motor 17 is electrically connected to the single chip microcomputer 13 . In this embodiment, the motor 17 includes two motors (see FIG. 2 ).

In this embodiment, a single-chip microcomputer 13 and a storage battery 15 are respectively arranged on both sides of the support rod 18 . The single-chip microcomputer 13 is electrically connected to the battery 15 , the pressure sensor 161 and the motor 17 respectively (see FIG. 3 ). When the single-chip microcomputer 13 sends a turning command to the motor 17 to drive the motor 17 to rotate, and then drive the two support rods 18 to rotate the pressure-sensitive plate 16 until the rotating pressure-sensitive plate 16 touches the support rod 18 below A limit switch (not shown in the figure) stops. After a preset time (for example, 10 seconds), the single-chip microcomputer 13 sends a reverse signal to the motor 17 to close the pressure-sensitive plate 16 . When the pressure sensing board 16 touches a card 21 (that is, the pressure sensing board 16 reaches a closed state), the single-chip microcomputer 13 sends a stop signal to the motor 17 . Since the weight of the outer half of the pressure sensing plate 16 is slightly greater than the weight of the inner half, the pressure sensing plate 16 is in a normally closed state. In this embodiment, the single-chip microcomputer 13 adopts the 89C51 single-chip microcomputer, which has the advantages of high reliability, low cost, simple circuit and convenient use.

The storage battery 15 is arranged as an end corresponding to the single-chip microcomputer 13, and is electrically connected with the solar panel 14, and the storage battery 15 is used to receive the electric energy generated by converting light energy of all the solar panels, and convert the electric energy Stored to provide power to other components of the entire solar energy bin.

In this embodiment, the solar energy-friendly dustbin also includes an infrared sensor 19 (see FIG. 3 ), the infrared sensor is arranged on the top of the inner tank 111 and is electrically connected to the single-chip microcomputer 13; The infrared sensor includes an infrared emitting device 191 and an infrared receiving device 192 . When the inner container 111 is filled with garbage, the infrared sensor 19 in the casing 11 will be triggered. The infrared sensor 19 sends a signal to the microcontroller 13 .

In this embodiment, the solar energy-friendly garbage bin further includes a display screen, and the display screen is arranged on the outer surface of the cover body 12 . Optionally, the display screen is a liquid crystal display screen 20 . When the single-chip microcomputer 13 receives the signal sent by the infrared sensor, the single-chip microcomputer 13 immediately sends an instruction to the liquid crystal display 20, so that the liquid crystal display 20 on the outer surface of the cover 12 displays a "full" prompt. At the same time, the motor 17 stops running after receiving a signal from the single-chip microcomputer 13, so that the pressure-sensitive plate 16 of the trash can is no longer turned over, thereby avoiding the problem of overflowing out of the box due to too much garbage.

Referring to Fig. 3, Fig. 3 is a connection schematic diagram of a single-chip microcomputer of a solar energy environment-friendly dustbin of the present invention.

The solar panel 14 converts light energy into electrical energy and stores it in the storage battery 15 . The storage battery 15 is electrically connected with the single-chip microcomputer 13, the infrared sensor 19, the pressure sensor 161, the motor 17 and the liquid crystal display screen 20 respectively, so as to provide electric energy. The pressure sensor 161 sends a signal to the single-chip microcomputer 13 after receiving external pressure, and the single-chip microcomputer 13 controls the motor 17 to drive the two support rods 18 in the cover body 12 to make the pressure-sensitive plate 16 rotate. When the infrared sensor 19 detects that the rubbish in the dustbin is full, it sends a signal to the single-chip microcomputer 13, and the single-chip microcomputer 13 prompts through the liquid crystal display 20 after receiving the signal.

The above are only preferred embodiments of the present utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the structure of the present utility model, some improvements and modifications can also be made. It should be regarded as the protection scope of the present utility model. the
