Description

Technical Field

[0001] The utility model belongs to the technical field of garbage bins, and in particular relates to a manual and automatic dual-purpose intelligent garbage bin. Background Art

[0002] A trash can is a container for holding garbage and waste, which can be seen everywhere. People place many trash cans outdoors and indoors to put garbage. The trash cans on the market are mainly divided into the following types: one is an open trash can, which has only an opening but no door. Although it is convenient to put garbage in, the garbage is exposed to the outside, and odors and mosquitoes are scattered everywhere, which is neither beautiful nor sanitary; another is a lidded trash can, which is provided with a door. Although it can hide the garbage in the trash can and make the surrounding environment clean and sanitary, people have to open the lid by hand before putting the garbage in, so that people can easily come into contact with germs and have the hidden danger of infection; the third is a pedal-type open-lid trash can, which does not require direct contact with the trash can by hand, avoiding contact with germs, but this pedal-type open-lid trash can is generally small in size, and the lid is small and light, and can be easily opened by stepping on the lid, and the pedal-type open-lid is not suitable for trash cans with heavy lids and large volumes.

[0003] With the development of science and technology, induction trash cans have gradually appeared on the market in recent years. Induction trash cans are controlled by circuit chips and consist of infrared detection devices and mechanical electronic drive systems. As long as a person approaches the sensing area, the lid will open automatically, and the lid will close automatically after the person leaves the sensing area for a few seconds. This type of trash can adopts an induction flip cover design, which is flexible and convenient. It can easily throw away garbage without manual or footstepping, which is convenient and hygienic, and avoids contact infection. The utility model patent "A smart environmentally friendly trash can" with application number 201710488533.2 converts solar energy into electrical energy through solar panels, and then uses a photovoltaic charging controller to charge the battery with a stable voltage. When a person approaches the infrared sensor at the front end of the box, the infrared sensor transmits a signal to the steering gear, and the steering gear rotates counterclockwise to drive the automatic shaft to rotate so that the automatic garbage door moves clockwise, and the automatic garbage door opens. When the person leaves the front end of the box, the steering gear returns to its initial state, and the automatic garbage door moves counterclockwise and returns to a closed state. However, the patent still has some shortcomings. The specific reasons are as follows: on rainy days, the infrared sensor is prone to malfunction, causing the steering gear to fail to work, the garbage door cannot be opened, and the garbage bin cannot be used. In addition, any failure in any component of the control system will cause the door of the garbage bin to fail to open. Utility Model Content

[0044] like Figure 5 As shown, the solar power supply system 22 supplies power to the control assembly 2; the solar power supply system 22 includes a solar panel 19, a solar controller 20 and a battery 21; the solar panel 19 is connected to the solar controller 20 by wires, and the battery 21 is connected to the solar controller 20 by wires.

[0045] like Figure 1 As shown, the control box 29 is arranged outside the box body 1 and fixed on the top of the box body 1. Fig. 9 As shown, the solar controller 20, the battery 21, all the dual output power-off delay relays 13, all the normally open switches 12, all the fuses 18, all the rectifier diodes 30, the speaker driver 24, the broadcasting speaker 25 and the raindrop control relay 36 are all arranged inside the control box 29. The main power switch 23, all the induction probes 11, all the manual switch buttons 15 and the raindrop sensor 17 are arranged on the side wall of the control box 29. Figure 8 As shown, the solar panel 19 is arranged on the top of the control box 29.

[0046] The method for automatically opening and closing the door of the intelligent garbage bin of the utility model is as follows:

[0047] When there is sufficient sunlight, the solar panel 19 collects sunlight and converts light energy into electrical energy, which is then supplied to the control assembly 2 through the solar controller 20, providing a 12V DC voltage to the control assembly 2. The solar controller 20 can also charge the battery 21 and store the electrical energy in the battery 21. In the absence of sunlight, the battery 21 can also supply power to the control assembly 2 through the solar controller 20. The solar controller 20 can monitor the working status of the solar panel 19 in real time, adjust the power output status, and protect the circuit of the control assembly 2. The solar controller 20 is a mature product on the market and can be purchased directly.

[0048] The positive terminal V+ of the power supply of the dual-output power-off delay relay 13 is connected to a 12V DC voltage (provided by the solar power supply system 22 ), and the delay module 35 is pre-set with a delay disconnection time.

[0049] When it is not raining, the positive electrode 27 and the negative electrode 28 of the raindrop sensor 17 are in a disconnected state, the relay coil 16 is not energized, the normally closed contact 14 is in a closed state, and the normally open switch 12 is connected to a 12V DC voltage (provided by the solar power supply system 22) through the normally closed contact 14. When a person approaches the trash can, the induction probe 11 senses a signal, the corresponding normally open switch 12 is closed, and the signal input terminal IN of the corresponding dual-output power-off delay relay 13 obtains a 12V high level, and the double-pole double-throw relay 34 is actuated: the first contact common terminal COM1 is connected to the first normally open contact NO1, and the second contact common terminal COM2 is connected to the second normally open contact NO2; the dual-output power-off delay relay 13 outputs a positive 12V voltage to the motor 9, and the corresponding motor 9 works and rotates forward, extending the telescopic rod 10, and the disc 8 at the end of the telescopic rod 10 pushes the roller 5 to push the box door 3 out, and the box door 3 is opened for people to throw garbage. Figure 2 As shown. When a person leaves the trash bin, the induction probe 11 senses that the signal disappears, the corresponding normally open switch 12 is disconnected, and the corresponding signal input terminal IN of the dual-output power-off delay relay 13 has no 12V high-level input, but during the delay time, the double-pole double-throw relay 34 remains in its original state, and the door 3 is still in the open state. After the delay time is over, the double-pole double-throw relay 34 switches: the first contact common terminal COM1 is connected to the first normally closed contact NC1, and the second contact common terminal COM2 is connected to the second normally closed contact NC2; the dual-output power-off delay relay 13 outputs a reverse 12V voltage to the motor 9, and the corresponding motor 9 rotates in the opposite direction, the telescopic rod 10 retracts, and the door 3 is closed. Fig.10 After the telescopic rod 10 is fully retracted, the limit switch inside the motor 9 is actuated to cut off the power supply, and the motor 9 stops working.

[0050] When it rains, the battery 21 supplies power to the control assembly 2 through the solar controller 20. Rainwater drips into the metal box 26 through the raindrop inlet hole 31. When the rainwater contacts the positive electrode 27 and the negative electrode 28 at the same time, the conductivity of the water will make the positive electrode 27 and the negative electrode 28 connected and current will pass through, the raindrop sensor 17 will be turned on, and then the voltage will be applied to the relay coil 16, all the normally closed contacts 14 will be disconnected, and then all the sensing probes 11 will be shielded, making all the sensing probes 11 unusable, and the normally open switch 12 will be in the disconnected state; if the sensing probe is not shielded, when it rains, rainwater drips on the sensing probe, the sensing probe will have an induction signal, and the dual output power-off delay relay will open the box door. If the box door is in the open state for a long time, a large amount of rainwater will pour into the garbage bin. In order to prevent such a situation from happening, the control assembly has added a raindrop sensing unit. When the raindrop sensor senses rainwater, the raindrop sensing unit is energized, and the raindrop sensing unit will shield all the sensing probes. The manual switch button 15 is connected to a 12V DC voltage (provided by the solar power supply system 22). If garbage needs to be disposed, the person presses the manual switch button 15, and the manual switch button 15 is closed. The corresponding signal input terminal IN of the dual-output power-off delay relay 13 obtains a 12V high level, and the double-pole double-throw relay 34 is actuated: the first contact common terminal COM1 is connected to the first normally open contact NO1, and the second contact common terminal COM2 is connected to the second normally open contact NO2; the dual-output power-off delay relay 13 outputs a positive 12V voltage to the motor 9, and the corresponding motor 9 works and rotates forward, extending the telescopic rod 10, and the disc 8 at the end of the telescopic rod 10 pushes the roller 5 to push the box door 3 out, and the box door 3 is opened for people to throw garbage. Figure 2 As shown. After pressing, the manual switch button 15 rebounds and disconnects, and the corresponding signal input terminal IN of the dual-output power-off delay relay 13 has no 12V high-level input, but during the delay time, the double-pole double-throw relay 34 still maintains the original state, and the door 3 is still in the open state. After the delay time is over, the double-pole double-throw relay 34 switches: the first contact common terminal COM1 is connected to the first normally closed contact NC1, and the second contact common terminal COM2 is connected to the second normally closed contact NC2; the dual-output power-off delay relay 13 outputs a reverse 12V voltage to the motor 9, and the corresponding motor 9 rotates in the opposite direction, the telescopic rod 10 retracts, and the door 3 is closed. Fig.10 After the telescopic rod 10 is fully retracted, the limit switch inside the motor 9 is actuated to cut off the power supply, and the motor 9 stops working.

[0051] like Fig.11 As shown, a handle is provided on the outside of the door 3. If any of the solar power supply system 22, the control assembly 2 or the execution assembly fails and cannot be used, a person can manually open the door 3 through the handle to put out garbage without affecting the normal use of the trash can.
