[0031] 9 trash cans Detailed Implementation
[0032] The purpose of this utility model is to provide an automatic prompt and cover opening / closing device for garbage sorting. The following describes this utility model in further detail with reference to specific embodiments.
[0033] like Figure 1 As shown, the automatic garbage sorting prompt and cover opening device consists of a column assembly 1, a transmission assembly 2, an electrical control box 3, a sensing device 5, and a power mechanism 6. The sensing device 5 can be a sensor switch or sensor module used on existing sensor lights. When someone approaches, it sends a signal to the electrical control box 3; when the person leaves, it sends another signal. The column assembly 1 consists of a hollow column 10 and a base 11. The transmission assembly 2 is installed on the top of the hollow column 10, and the power mechanism 6 is installed on the transmission assembly 2. The electrical control box 3 is installed on the hollow column 10. Figure 6 As shown, the transmission assembly 2 has a housing 20, and a horizontally movable sliding frame 21 is installed inside the cavity of the housing 20. A rotating shaft 22 is horizontally mounted on the sliding frame 21, and a large gear 23 and a pulley 24 are fixedly mounted on the rotating shaft 22. The rotating shaft 22 can drive the large gear 23 and the pulley 24 to rotate synchronously. A traction belt 25 is installed on the pulley 24, and one end of the traction belt 25 extends out of the housing 20 to connect with the trash can lid. For easy connection and disconnection, a clip can be installed on the traction belt 25 to connect with the handle on the lid. The clip can be an existing stainless steel clothespin.
[0034] like Figure 2As shown, the other end of the traction belt 25 extends into the hollow column 10 to install a heavy block 29. The upper limit switch 12 and the lower limit switch 13 are installed in the hollow column 10, and the upper limit switch 12 is located above the lower limit switch 13. The heavy block 29 can correspond to the upper limit switch 12 or the lower limit switch 13, respectively. The upper limit switch 12 and the lower limit switch 13 can be existing proximity switches to achieve the following functions: when the heavy block 29 moves up to the upper limit switch 12, the barrel cover of the barrel is just closed, at this time, the upper limit switch 12 detects the heavy block 29, transmits a signal to the electric control box 3, and the electric control box 3 controls the motor 60 to stop; when the heavy block 29 moves down to the lower limit switch 13, the barrel cover of the barrel has been opened to the appropriate angle, at this time, the lower limit switch 13 detects the heavy block 29, transmits a signal to the electric control box 3, and the electric control box 3 controls the motor 60 to stop.
[0035] As shown in Figure 6 , one side of the sliding frame 21 is horizontally installed with a guide rod 28, one end of the guide rod 28 extends out of the shell 20, the guide rod 28 is sleeved with a first spring 27 on the outer periphery, and the guide rod 28 is provided with a baffle 26 capable of pressing the first spring 27. The power mechanism 6 is composed of a motor 60 and a protective cover 61. The protective cover 61 is connected with the shell 20, the motor 60 is installed in the protective cover 61, the motor shaft of the motor 60 extends into the shell 20 to install a pinion 63, and the pinion 63 is engaged with the gear 23. The bottom of the shell 20 is vertically installed with a positioning mechanism 7, and the positioning mechanism 7 can limit the position of the sliding frame 21.
[0036] As shown in Figure 10 and 11 , the positioning mechanism 7 has a guide sleeve 70 connected with the bottom of the shell 20. The guide sleeve 70 is installed with a positioning column 71 and a second spring 74. The top of the positioning column 71 is provided with an inclined surface 72. The top of the positioning column 71 cooperates with the sliding frame 21, and the bottom of the positioning column 71 is installed with a pull rod 73. The second spring 74 is located on the outer periphery of the pull rod 73 and below the positioning column 71. As shown in Figure 12As shown, a lever 77 is mounted on the lower part of the pull rod 73, extending out of the guide sleeve 70. The lever 77 has a second through hole 770 through which the traction belt 25 passes. A lever block 76 is fixedly mounted on the traction belt 25. Both the lever block 76 and the lever 77 are located above the upper limit switch 12. Sufficient distance should be maintained between the lever block 76 and the pulley 24 to ensure that they do not contact each other when the lid is closed. When the weight 29 moves down to the lower limit switch 13, if the lower limit switch 13 does not transmit a signal to the control box 3 in time to control the motor 60 to stop, the weight 29 and the traction belt 25 will continue to move down; when the weight 29 exceeds the set lower limit position, the lever 76 can continue to pull the lever 77 down, so that the lever 77 overcomes the elastic force of the second spring 74 through the pull rod 73 to pull down the positioning post 71; after the positioning post 71 separates from the sliding frame 21, the first spring 27 pushes the sliding frame 21 through the baffle 26 and the guide rod 28. Figure 6 The indicated position is moved upwards, separating the large gear 23 from the small gear 63, thereby preventing damage to the motor 60 due to overload. Both the pull rod 73 and the lever 77 are located inside the hollow column 10. The electrical control box 3 has a housing 30, with a panel 31 at the front. Buttons are installed on the panel 31 to control the automatic waste sorting prompt and cover opening / closing device for powering on and off.
[0037] During installation and use, place the column assembly 1 behind the trash can 9. The base 11 can be fixed to the ground with bolts. One end of the traction belt 25 is clamped to the handle of the trash can 9 lid using a clip. Pressing the start button on the panel 31 activates the automatic trash sorting prompt and lid opening / closing device. When someone approaches the trash can 9 to a set distance, the sensor 5 detects the approach and sends a signal to the control box 3. The control box 3 controls its internal sound device to play a recording to remind the user what type of trash should be placed in the trash can 9. Simultaneously, the control box 3 signals the motor 60, causing it to rotate forward and pull the lid open via the traction belt 25. At the same time, the weight 29 moves to the lower limit switch 13. When the weight 29 triggers the lower limit switch 13, the switch sends a signal to the control box 3, which then stops the motor 60. At this point, the lid opens to the set angle, facilitating trash disposal for the user. When the user leaves the trash can 9, the sensor 5 sends a signal to the control box 3. The control box 3 can control the sound device inside to play the recording. On the other hand, the control box 3 sends a signal to the motor 60, the motor 60 reverses, and the lid closes and resets under the action of gravity. At the same time, the weight 29 moves toward the upper limit switch 12. When the weight 29 triggers the upper limit switch 12, the upper limit switch 12 sends a signal to the control box 3, and the control box 3 controls the motor 60 to stop.
[0038] Since the automatic garbage sorting reminder and lid opening / closing device is located outdoors, it is greatly affected by external factors. If the lower limit switch 13 malfunctions, even if the weight 29 moves to the lower limit switch 13, the lower limit switch 13 will not send a signal to the control box 3 in time. In this case, the motor 60 will drive the traction belt 25 to continue moving. When the weight 29 moves down beyond the set distance, the weight 29 will pull the lever 76 down the lever 77, thereby separating the positioning post 71 from the sliding frame 21. This prevents the motor 60 from being damaged due to overload or from breaking the lid. If someone finds that the lid has not been closed for a long time when no one is around, they can turn off the automatic garbage sorting reminder and lid opening / closing device using the button on the panel 31 and wait for maintenance personnel to inspect it. After replacing the lower limit switch 13, first lift the weight 29 so that the positioning post 71 moves upward and resets under the action of the second spring 74, then place the sliding frame 21... Figure 6 At the position shown, push the sliding frame 21 to the right to re-engage the large gear 23 with the small gear 63; during the translation process, the sliding frame 21 first presses down the positioning column 71 through the inclined plane 72. After the sliding frame 21 passes the positioning column 71, the positioning column 71 moves up and resets under the action of the second spring 74 to position the sliding frame 21. After releasing the weight 29, the machine can be turned on and run normally.
[0039] The automatic garbage sorting prompt and lid opening / closing device can also be configured in the following ways in terms of programming:
[0040] 1. Upon startup, a voice prompt will say, "Welcome to the waste sorting system. System checks are now in progress."
[0041] 2. When someone approaches the trash can, the lid will open automatically, accompanied by a corresponding voice prompt, such as: This is hazardous waste;
[0042] 3. When the person leaves, a voice prompt will say, "Thank you for sorting your trash in advance."
[0043] 4. When a trash can is not placed in its proper position, a voice prompt will appear saying, "Please check if the trash can is placed in its proper position."
[0044] 5. If the belt clip that pulls the trash can lid is not engaged, causing the trash can lid to fail to open automatically, a voice prompt will appear saying, "Please check if the belt clip is properly engaged with the trash can lid."
[0045] 6. When the trash can lid cannot be closed, a voice prompt will say, "Please check and troubleshoot the reason why the trash can lid cannot be closed."
[0046] 7. When an abnormality occurs due to human error, a voice prompt will appear saying "An abnormality has occurred, please check." After the fault is resolved, the system will automatically perform a power-on test and a voice prompt will appear saying "Power-on test is now in progress" before resuming normal operation.
[0047] 8. When the working voltage is abnormal, there is a voice prompt "Please check whether the working power supply is normal"
[0048] As shown in Figure 1 The top of the shell 20 is provided with a solar cell power supply system 4, which can provide power for the garbage classification automatic prompting and cover opening and closing device, and maintain its normal operation. The solar cell power supply system 4 can play a role of rain and sunlight shielding for the transmission assembly 2 and the power mechanism 6, so that they are less affected by the outside world. The battery and control circuit of the solar cell power supply system 4 and other main components can be located in the electric control box 3.
[0049] In order to enable the large gear 23 and the small gear 63 to be stably engaged during normal operation, and to enable the slide frame 21 to move stably when the large gear 23 and the small gear 63 need to be separated, the side of the slide frame 21 is provided with a guide block 210, and the inner wall of the shell 20 is provided with a guide groove 200, which is in sliding fit with the guide block 210.
