[0019] In this embodiment, two sets of filter plates 35 are provided, and a number of percolation holes 36 are evenly spaced on the surface of the filter plates 35. The design of the filter plates 35 and the percolation holes 36 facilitates the filtration of leachate generated during the garbage decomposition process, thereby preventing the garbage at the bottom of the inner bin 31 from being soaked in leachate for a long time, which accelerates decomposition and produces an unpleasant odor. The guide slope 34 is inclined towards the filter plates 35, and the guide slope 34 can guide the leachate. The size of the shield 37 corresponds to the size of the filter plates 35, and two sets of shield 37 are provided. The two sets of shield 37 are fixedly connected by a connecting rod 371.

Users can empty the leachate stored inside by pulling out the leachate storage tank 19. A support plate 16 is provided at the connection between the storage area 12 and the storage area 11. The support plate 16 is used to support the weight of the inner bin 31 of the garbage can. A first opening 14 is provided at the connection between the detection area 13 and the storage area 11, and the detection area 13 and the storage area 11 are connected through the first opening 14. The size of the ventilation plate 61 corresponds to the first opening 14. By moving the ventilation plate 61, the first opening 14 is blocked, thereby controlling the connection between the storage area 11 and the detection area 13.

[0023] In this embodiment, a first adjusting screw 63 is provided inside the detection area 13. The first adjusting screw 63 meshes with the first threaded seat 62. The rotation of the first adjusting screw 63 can drive the ventilation plate 61 to move through the first threaded seat 62. The input end of the first drive motor 64 is electrically connected to the control panel 2 through a wire. The control panel 2 can control the opening and closing of the first drive motor 64. The output end of the first drive motor 64 is connected to the first adjusting screw 63 through a motor shaft. The first drive motor 64 can drive the first adjusting screw 63 to rotate.

[0024] In this embodiment, a second adjusting screw 69 is provided inside the detection area 13. The second adjusting screw 69 meshes with the second threaded seat 68.

[0025] In this embodiment, a second opening 141 is provided on the upper surface of the outer bin 1 of the trash can. The interior of the detection area 13 is connected to the outside through the second opening 141. A sealing gasket 661 is bonded to the lower surface of the sealing plate 66. The sealing gasket 661 can enhance the sealing performance of the sealing plate 66. The size of the sealing plate 66 corresponds to the second opening 141.

A connecting through hole 671 is provided on the upper surface of the sealing plate 66. A sliding rod 67 is provided on the upper surface of the outer bin 1 of the trash can. The sliding rod 67 passes through the sealing plate 66 through the connecting through hole 671. The design of the connecting through hole 671 and the sliding rod 67 can make the movement of the sealing plate 66 more stable.

[0026] In this embodiment, a solar cell array 41 is installed inside the detection area 13. The solar power panel 4 and the solar cell array 41 are electrically connected through wires. The design of the solar power panel 4 and the solar cell array 41 can provide power to the product. An alarm 42 is installed inside the detection area 13. The alarm 42 is electrically connected to the control panel 2 through wires. The alarm 42 can sound an alarm to remind staff to handle the situation. Several sets of mounting plates 51 are set inside the detection area 13. Several sets of odor sensors 5 are set with the same specifications. The several sets of odor sensors 5 are arranged in an array on the surface of the mounting plates 51. The array distribution of several sets of odor sensors 5 makes the detection effect more accurate.

[0027] Working principle: Users can flip open the baffle 15 and dispose of garbage into the inner bin 31 through the disposal port 32. After disposal, the baffle 15 automatically flips and closes under gravity, preventing odors from escaping through the disposal port 32. As the garbage decomposes inside the inner bin 31, the resulting liquid is guided by the ramp 34, passes through the filter plate 35 and leachate holes 36, and enters the leachate storage tank 19 inside the storage area 12. This design prevents garbage from being soaked in leachate for extended periods, thus avoiding accelerated decomposition and foul odors. Air circulates with the interior of the outer bin 1 of the trash can through the first opening 14 and the second opening 141. During the circulation, the odor sensor 5 monitors the components in the odor in real time to determine the decomposition status of the trash inside the inner bin 31. When the decomposition rate of the trash inside the inner bin 31 is below 30%, the first drive motor 64 drives the first threaded rod to rotate, causing the first threaded seat 62 and the ventilation plate 61 to move to the right, so as not to block the first opening 14. At the same time, the second drive motor 65 drives the second threaded rod to rotate, causing the second threaded seat 68 and the sealing plate 66 to move upward. The second opening 141 is not obstructed, thus achieving maximum ventilation. When the degree of decomposition of the garbage inside the inner bin 31 is between 30% and 70%, the first drive motor 64 drives the first threaded rod to rotate, causing the first threaded seat 62 and the ventilation plate 61 to move to the left, partially obstructing the first opening 141, thereby limiting the ventilation effect and reducing odor leakage. When the degree of decomposition of the garbage inside the inner bin 31 is above 70%, the second drive motor 65 drives the second threaded rod to rotate, causing the sealing plate 66 to be completely pressed down and obstructing the second opening 141, thereby preventing internal odor leakage. At the same time, the first drive motor 64 drives the first threaded rod to rotate, causing the ventilation plate 61 to completely obstruct the first opening 141. This design can prevent odor from entering the detection area 13, causing the odor sensor 5 to be immersed in odor for a long time, reducing the service life of the odor sensor 5. Subsequently, the alarm 42 sounds an alarm to remind staff to clean the inner bin 31 and the leachate storage tank 19 in time.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
