Description

TECHNICAL FIELD

[0001] The present application relates to the field of garbage classification and storage, and in particular to an intelligent dynamic volume regulation and classification garbage can and a use method thereof. BACKGROUND

[0002] In the current context of rapid social development and accelerated urbanization, the generation of municipal solid waste has increased dramatically, posing a significant challenge to urban management and environmental protection. Traditional garbage cans with fixed volumes are prone to overflow in high-traffic areas, affecting the cleanliness of the city and increasing the frequency and cost of garbage collection. In recent years, with the rapid development of advanced technologies such as artificial intelligence, the Internet of Things, and big data, intelligent and efficient waste disposal solutions have become a hot topic for research and practice. As an important part of smart city infrastructure, some existing intelligent garbage cans already have preliminary garbage classification capabilities, using image recognition technology to identify and sort incoming garbage. However, these products mostly fail to address the issue of fixed garbage container volume, which cannot be dynamically adjusted according to actual needs. In specific time periods or locations, such as after holidays or large events, the amount of garbage generated increases dramatically, and garbage cans with fixed volumes quickly fill up, failing to meet actual needs. To address these issues, various volume-adjustable technologies have been developed. While these technologies have played a positive role in environmental protection and improving waste storage efficiency, they still have some drawbacks and challenges. Some common drawbacks include poor automation, inconvenient manual operation, or lack of classification intervals.

[0003] For example, CN108861225A discloses a variable-volume garbage can, which includes a receiving cylinder, a support rod, a guide structure, a limiting block, a limiting structure, an adjusting rod, an adjusting sleeve, and a fixed ring. One half-ring structure of the fixed ring has two end portions with cylindrical structures that cooperate with the adjusting sleeve on the other half-ring structure to adjust the size of the accommodating space. The cylindrical structure of the adjusting sleeve is rotationally connected between the fixed ring on the support rod and the adjusting rod at the end of the fixed ring on the support rod. The adjusting sleeve is threadedly connected to the adjusting rod at the end of the fixed ring on the support rod. By turning the adjusting sleeve, the size of the accommodating space enclosed by the two fixed rings can be changed, allowing the garbage can to be used in different locations and facilitating the fixing of garbage bags of different sizes. The limiting block and the adjusting sleeve are used to fix the garbage bag. However, this patent has low automation and cannot be applied to large-scale scenarios. Additionally, the device cannot be used for classified garbage disposal.

[0004] For example, CN210437835U discloses a volume convertible classification garbage can, which comprises a box body and a plurality of small wheels. The box body is horizontally placed in a cuboid structure. The cuboid structure is divided into a recyclable garbage chamber and a non-recyclable garbage chamber by a vertical partition. The vertical partition is of movable structure. The vertical partition is fixed to the top and bottom of the box body through slide rails. Threaded sleeves are arranged on the front and rear positions of the middle part of the vertical partition. The threaded sleeves are perpendicular to the surface of the vertical partition. Threaded rod structures are arranged on the two threaded sleeves. The threaded rod structures are fixed to the box body and connected with driving devices outside the box body. The driving devices are connected with each other and synchronous. The patent cannot automatically adjust the garbage capacity. The design of the box body is not conducive to the application and deployment of the device. SUMMARY

[0017] A use method of an intelligent dynamic volume regulation and classification garbage can, comprising the following steps:

[0018] Step 1: After the classified garbage bins are installed and tested successfully, place them horizontally in the application environment and fix them to the installation base with the fixing screws. The staff will open the side door and hang the garbage bags on the various garbage bag fixing buckles. Start the electronic control system to start the classified garbage bins. The solar panel will start to store energy for the classified garbage bins. The electronic control system will initialize the classified garbage bins. The hydraulic rod will extend and slowly push down the third support plate. When the third support plate reaches one-quarter of the bottom of the garbage bin, the hydraulic rod will stop running.

[0019] Step 2: The second stepper motor of the screw lifting device controls the rotation of the second screw, which drives the linear slider to move vertically until the second support plate reaches half of the trash can under the drive of the linear slider, at which point the second stepper motor stops operating;

[0020] Step 3: The first stepper motor controls the first lead screw to rotate, which in turn controls the horizontal movement of the crossbar. The connecting rod, driven by the crossbar, controls the first support plate at the bottom to move vertically. When the volume of the hazardous waste storage device is one-quarter of the total internal volume of the trash can, the first stepper motor stops operating.

[0021] Step 4: Once the storage capacity of the four types of waste is equal, wait for waste to be deposited. The pressure sensor on each layer will be activated to identify the capacity of each type of waste.

[0022] Step 5: When a pressure sensor on a certain layer detects that the storage capacity of this type of waste has been exceeded, it sends a signal to the electronic control system. The electronic control system controls the three lifting devices to redistribute the capacity of various types of waste inside the device. The storage space of waste with a small amount of waste is reduced to make room for waste with a large amount of waste.

[0023] Step 6: When the ultrasonic sensor in the recyclable waste compression device detects that the amount of recyclable waste exceeds the warning line, it sends a signal to the electronic control system. The electronic control system controls the hydraulic rod to descend, pressing the pressure plate vertically downward to compress the recyclable waste and leave more space for storage.

[0024] Step 7: When all types of waste storage devices reach their maximum capacity, the electronic control system sends an alarm to remind staff to remove the waste bags from the garbage bag fasteners in time.

[0025] Step 8: After the staff changes the garbage bags, the electronic control system keeps the volume of each type of garbage at the same position as at the end of the last operation based on the recorded data. Steps 2 to 7 are repeated to start the next work cycle.

[0026] The present invention has the following beneficial effects:

[0027] 1. The trash can of this invention has different storage requirements for various types of trash in different application environments. Traditional trash can equipment will cause some types of trash cans to have excessive storage capacity, resulting in waste of resources, while other types of trash cans will not have enough capacity, resulting in overflow of trash and environmental pollution, which is not conducive to cultivating people's awareness of sorting. However, this invention can effectively change the volume of various types of trash, make full use of space resources, and increase the storage capacity of the device.

[0028] 2. This invention uses solar energy storage, which meets the requirements of clean energy and is more environmentally friendly.

[0031] 5. This invention makes it easier to place garbage bags by adding bag fixing buckles; it also makes it easier for staff to operate and prevents liquid from leaking out of the garbage, thus reducing pollution to the environment.

[0032] 6. This invention has a high degree of automation. The electronic control system automatically records and maintains the capacity of each type of waste, reducing the need for subsequent capacity changes and further reducing energy consumption. Attached Figure Description

[0050] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0051] Example 1:

[0052] See Figures 1-8A smart dynamic volume-controlled sorting trash can includes a main frame 8. The main frame 8 has three lifting devices inside: a scissor lift 2, a screw lift 3, and a hydraulic lift 4. The top of the scissor lift 2 is connected to the bottom of the top plate 505 of the waste storage device 5. The top of the hydraulic lift 4 is hinged to both sides of the top of the main frame 8. The piston rod of the hydraulic lift 4 is connected to the screw lift 3 via a connecting plate 405, driving the screw lift 3 to move up and down along the main frame 8. The bottom of the screw lift 3 is connected to the pressure plate 605 of the recyclable waste compression device 6. Three support plates are arranged between the three lifting devices, and together with the top plate 505 and bottom plate 504 of the waste storage device 5, they divide the interior of the trash can into four areas. A pressure sensor 101 is installed on the upper surface of each support plate, and the pressure sensor 101 is connected to an electronic control system 1. The main frame 8 is fitted with an outer shell structure 7. This invention effectively solves the problem of uneven distribution of storage capacity for various types of waste and the inability of existing waste storage devices to automatically adjust the volume of waste by adopting the above-mentioned classified waste bins. In specific use, the scissor lifting device 2, screw lifting device 3, and hydraulic lifting device 4 can compress the four independent chambers after division, thereby dynamically adjusting the waste storage space of different chambers to achieve the effect of maximizing space utilization.

[0053] Furthermore, the top and bottom of the scissor lift device 2 are respectively the top plate 505 and the first support plate 506 of the waste storage device 5. First sliding grooves 203 are respectively opened on both sides of the top plate 505 and the first support plate 506. A first limit switch 204 is installed at the end of the first sliding groove 203. The two ends of the connecting rod 201 are slidably supported inside the first sliding groove 203 by screws. The bottoms of the two connecting rods 201 located inside the first sliding groove 203 are connected by a crossbar 205. A first lead screw 206 is installed at the center of the crossbar 205 through threaded transmission. The end of the first lead screw 206 is connected to the first stepper motor 202. The two ends of the connecting rod 201 can slide horizontally within the first sliding groove 203 under the drive of the first stepper motor 202. Through the aforementioned scissor lift device 2, the height of the first support plate 506 can be dynamically adjusted, thereby achieving dynamic adjustment of the top hazardous waste storage cavity. In the specific operation, the first stepper motor 202 drives the first lead screw 206, which in turn drives the crossbar 205. The crossbar 205 then drives the connecting rod 201, which in turn moves the first support plate 506 at its bottom to achieve lifting and lowering, thus adjusting the space. Furthermore, since the scissor lift device 2 is fixed to the top of the device, the power requirement is low, so a single stepper motor is used for driving, reducing production costs. This also reduces the weight of the lifting equipment, and the installation of limit switches makes the device safer and more reliable.

[0054] Furthermore, the screw lifting device 3 includes a mounting base 302, with a second screw 301 rotatably mounted between the mounting bases 302. A second stepper motor 304 is connected to the bottom of the mounting base 302, and the spindle of the second stepper motor 304 is connected to the second screw 301. A linear slider 303 is mounted on the second screw 301 via threaded transmission. A linear bearing 306 is mounted on the linear slider 303, and the linear bearing 306 slides with linear guide rails 307 located on both sides of the second screw 301. A second limit switch 305 is provided on the top of the second screw 301. Through the aforementioned screw lifting device 3, the lifting and lowering adjustment of the second support plate 507 can be achieved, thereby realizing the spatial adjustment between the other waste storage chamber and the kitchen waste storage chamber. During operation, the second stepper motor 304 drives the second lead screw 301, which in turn drives the linear slider 303 to slide up and down along the linear guide rail 307. This, in turn, drives the second support plate 507 to adjust the height, thereby dynamically adjusting the storage chambers for other waste and kitchen waste.

[0055] Furthermore, the hydraulic lifting device 4 includes a hydraulic cylinder 402. The cylinder base of the hydraulic cylinder 402 is hinged to the top of the main frame 8 of the garbage bin. The circular notch at the bottom of the hydraulic rod 403 of the hydraulic cylinder 402 is fitted with the bushing of the push rod 404. The bottom of the push rod 404 is connected to a connecting plate 405. The connecting plate 405 is fixedly connected to the mounting base 302 of the screw lifting device 3. The two sides of the connecting plate 405 are slidably disposed in the sliding grooves inside the frame 407 of the main frame 8 of the garbage bin. An aluminum profile base 401 is fixedly installed at the bottom of the frame 407, and fixing bolts 406 are respectively installed at both ends of the aluminum profile base 401. The hydraulic lifting device 4 described above can realize the lifting and adjustment of the entire screw lifting device 3, thereby realizing the adjustment of the recyclable waste storage cavity. During operation, the hydraulic cylinder 402 drives the hydraulic rod 403, which in turn drives the push rod 404. The push rod 404 drives the connecting plate 405 and the screw lifting device 3 to achieve overall lifting and movement. The above setup, through the pushing and pulling of a high-power hydraulic cylinder, satisfies both the power requirements for compressing recyclable waste and the strength requirements for supporting the two lifting devices.

[0056] The device is connected and fixed to the ground by aluminum profile base 401 and fixing bolts 406, which avoids the possibility of the device tipping over due to the shift of the center of gravity when the internal lifting device is in operation.

[0057] Furthermore, the cavity between the top plate 505 and the first support plate 506 of the waste storage device 5 constitutes a hazardous waste storage cavity; hazardous waste can be stored through the hazardous waste storage cavity.

[0058] Furthermore, the cavity between the first support plate 506 and the second support plate 507 constitutes a storage cavity for other types of waste, and the second support plate 507 is fixedly mounted on the linear slider 303 of the screw lifting device 3. This storage cavity enables the storage of other types of waste.

[0059] Furthermore, the cavity between the second support plate 507 and the third support plate 508 of the waste storage device 5 constitutes a kitchen waste storage cavity. The third support plate 508 is fixedly installed at the bottom end of the second stepper motor 304 of the screw lifting device 3 and moves vertically under the drive of the hydraulic lifting device 4. The kitchen waste storage cavity enables the storage of kitchen waste.

[0060] Furthermore, the cavity between the third support plate 508 and the bottom plate 504 of the waste storage device 5 constitutes a recyclable waste storage cavity, and the bottom plate 504 is fixed on the aluminum profile base 401 of the hydraulic lifting device 4; recyclable waste storage can be realized through the recyclable waste storage cavity.

[0061] Furthermore, the interior sides of the hazardous waste storage chamber, other waste storage chamber, kitchen waste storage chamber, and recyclable waste storage chamber are all equipped with garbage bag fixing buckles 501. These buckles facilitate the hanging of garbage bags. These features are designed according to the weight of each type of waste to prevent the device from tipping over due to being top-heavy, thus improving the device's safety.

[0062] Furthermore, the recyclable waste compression device 6 includes a compression baffle 601 and a pressure plate 605. The compression baffle 601 is slidably installed in the third sliding groove 604 on the inner side of the two side plates of the base plate 504. Ultrasonic sensors 602 are installed on the inner walls of the two side plates of the base plate 504. The pressure plate 605 is fixed to the bottom end of the third support plate 508, and several round nails 603 are provided at the bottom end of the pressure plate 605. These features allow the device to compress recyclable waste that is about to overflow, further improving space utilization and facilitating subsequent recycling work for staff. Simultaneously, the addition of round nails allows for better compression of sealed recyclable waste such as plastic bottles.

[0063] Furthermore, the outer casing structure 7 includes an outer casing 706, with a solar panel 701 mounted on the top, a side sliding door 702 installed on the rear, four delivery ports 703 and corresponding markings 705 on the front, and handles 704 fixed on both sides. This structure allows for better power supply to the device, resulting in cleaner energy, a more environmentally friendly device, and lower operating costs.

[0064] Example 2:

[0065] A method for using an intelligent dynamic volume-controlled sorting trash can includes the following steps:

[0066] Step 1: After the classified garbage bins are installed and tested successfully, place them horizontally in the application environment and fix them to the installation base with fixing screws 406. The staff will open the side door 702 and hang the garbage bags on the various garbage bag fixing buckles 501. Start the electronic control system 1 to start the classified garbage bins. The solar panel 701 will start up to store energy for the classified garbage bins. The electronic control system 1 will initialize the classified garbage bins. The hydraulic rod 403 will be pushed out, and the third support plate 508 will be slowly pushed down. When the third support plate 508 reaches one-quarter of the bottom of the garbage bin, the hydraulic rod 403 will stop running.

[0067] Step 2: The second stepper motor 304 of the screw lifting device 3 controls the rotation of the second screw 301, which drives the linear slider 303 to move vertically until the second support plate 507 reaches halfway to the trash can under the drive of the linear slider 303, at which point the second stepper motor 304 stops operating.

[0068] Step 3: The first stepper motor 202 controls the first lead screw 206 to rotate, controls the horizontal bar 205 to move horizontally, and the connecting rod 201 controls the bottom first support plate 506 to move vertically under the drive of the horizontal bar 205. When the volume of the hazardous waste storage device is one-quarter of the total internal volume of the garbage can, the first stepper motor 202 stops operating.

[0069] Step 4: Once the storage capacity of the four types of waste is equal, wait for waste to be deposited. Pressure sensor 101 on each layer will be activated to identify the capacity of each type of waste.

[0070] Step 5: When a pressure sensor 101 of a certain layer detects that the storage capacity of this type of waste exceeds the storage capacity, it sends a signal to the electronic control system 1. The electronic control system 1 controls the three lifting devices to redistribute the capacity of various types of waste inside the device. The storage space of waste with a small amount of waste is reduced to make room for waste with a large amount of waste.

[0071] Step 6: When the ultrasonic sensor 602 in the recyclable waste compression device 6 detects that the amount of recyclable waste exceeds the warning line, it sends a signal to the electronic control system 1. The electronic control system 1 controls the hydraulic rod 403 to descend, pressing the pressure plate 605 vertically downward to compress the recyclable waste and leave more space for storage.

[0072] Step 7: When all types of waste storage devices reach their maximum capacity, the electronic control system 1 sends an alarm to remind staff to remove the waste bags from the waste bag fixing buckle 501 in time. At the same time, the electronic control system 1 records the volume ratio of each type of waste. This completes one operation.

[0073] Step 8: After the staff changes the garbage bags, the electronic control system 1 keeps the volume of each type of garbage unchanged from the position at the end of the last time based on the recorded data, and repeats steps 2 to 7 to start the next work cycle.

[0074] In summary, the present invention provides an intelligent dynamic volume-controlled sorting trash can and its working method. By setting up four different types of variable waste storage devices, different volume adjustments are made for different amounts of waste in different scenarios, making full use of the internal space of the trash can, improving people's awareness of sorting, and also making it more convenient for staff to operate a waste sorting and storage device.

9. The method of using an intelligent dynamic volume-controlled sorting trash can according to claim 8, characterized in that, Includes the following steps: Step 1: After the classified garbage bins are installed and debugged to be qualified, place the classified garbage bins horizontally in the application environment, fix the fixing bolts (406) to the installation base, the staff pulls open the side door (702), and then hangs the garbage bags on the various garbage bag fixing buckles (501). Start the electric control system (1) to start the classified garbage bins. The solar panel (701) starts up to store energy for the classified garbage bins. The electric control system (1) initializes the classified garbage bins. The hydraulic rod (403) pushes out and slowly pushes down the third support plate (508). When the third support plate (508) reaches one-quarter of the bottom of the garbage bin, the hydraulic rod (403) stops running. Step 2: The second stepper motor (304) of the screw lifting device (3) controls the rotation of the second screw (301), which drives the linear slider (303) to move vertically until the second support plate (507) reaches half of the trash can under the drive of the linear slider (303), and the second stepper motor (304) stops operating. Step 3: The first stepper motor (202) controls the first lead screw (206) to rotate, controls the horizontal bar (205) to move horizontally, and the connecting rod (201) controls the bottom first support plate (506) to move vertically under the drive of the horizontal bar (205). When the volume of the hazardous waste storage device is one-quarter of the total internal volume of the garbage can, the first stepper motor (202) stops operating. Step 4: When the volumes of the four types of waste storage devices are equal, wait for waste to be deposited. The pressure sensor (101) of each layer is activated to identify the capacity status of each type of waste. Step 5: When a pressure sensor (101) of a certain layer detects that the storage capacity of this type of waste exceeds the storage capacity, it sends a signal to the electronic control system (1). The electronic control system (1) controls the three lifting devices to redistribute the capacity of various types of waste inside the device. The storage space of waste with a small amount of waste is reduced to make room for waste with a large amount of waste. Step 6: When the ultrasonic sensor (602) in the recyclable waste compression device (6) detects that the amount of recyclable waste exceeds the warning line, it sends a signal to the electronic control system (1). The electronic control system (1) controls the hydraulic rod (403) to descend and press the pressure plate (605) vertically downward to compress the recyclable waste and leave more space for storage. Step 7: When all types of waste storage devices reach their upper limit, the electronic control system (1) sends an alarm to remind staff to remove the waste bags from the garbage bag fixing buckle (501) in time. At the same time, the electronic control system (1) records the volume ratio of each type of waste. This means that one work has been completed. Step 8: After the staff changes the garbage bags, the electronic control system (1) keeps the volume of various types of garbage unchanged at the position at the end of the last time according to the recorded data, and repeats Step 2 to Step 7, which is the next work cycle.
