Description

Technical Field

[0001] The present invention relates to the technical field of trash cans, in particular to an intelligent classification trash can. Background Art

[0002] With the rapid development of modern technology and policy support, the application scenarios of smart trash cans are constantly expanding. From homes and schools to businesses and public places, they can be found everywhere. Smart trash cans can automatically identify the type of waste and significantly improve waste disposal efficiency while reducing manpower input.

[0003] The advantages of smart waste sorting bins lie in their ability to identify, accurately classify, and manage waste more efficiently. This not only enhances convenience, but also allows smart locks to connect to the Internet of Things (IoT), further building a unified smart ecosystem. Therefore, while ensuring environmental protection, accurate classification and user-friendly functionality are the goals of modern smart waste sorting bins.

[0004] At present, the smart sorting trash cans on the market are generally powered by charging or batteries, and their battery life is relatively poor. In addition, the smart sorting trash cans on the market have inner buckets arranged in rows, the sorting mechanism is complicated, and there is unreasonable space utilization. Summary of the Invention

[0005] The object of the present invention is to provide a space-saving and easy-to-manufacture intelligent classification trash can to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the technical solutions of the present invention are as follows.

[0007] A smart trash bin for sorting trash comprises an outer cylinder and an upper cover with a drop-in opening. An identification platform is disposed above the outer cylinder and below the upper cover, and has a drop-in opening. A gate is disposed below the identification platform and can be opened and closed by a first drive mechanism. A rotating platform is mounted horizontally and rotatably below the outer cylinder, with multiple inner barrels positioned on the rotating platform, their openings aligned with the drop-in opening. A second drive mechanism is mounted inside the outer cylinder and is used to rotate the rotating platform.

[0008] As can be seen, by driving the rotating table through the second drive device, the multiple inner barrels can be rotated in sequence to the bottom of the drop-in port. At this time, the gate is driven by the first drive device to rotate, allowing the garbage above to fall through the drop-in port into the inner barrel below. Compared with the traditional smart classification trash cans on the market that arrange the inner barrels in rows, the classification mechanism is simpler and the space utilization is more reasonable, making the structure more compact and practical. In addition, during the intelligent identification process, if the user finds that there are items in the trash that need to be thrown away, they can remove them in time without having to search from the bottom of the trash can. The identification and detection process is exactly the period when the user hesitates to discard the garbage, killing two birds with one stone.

[0009] Furthermore, a main control board is mounted on the inside of the upper cover. A camera is mounted on the top of the inner side of the upper cover and is used to collect image information of garbage on the upper side of the identification platform. A distance sensor is mounted on the lower side of the identification platform, measuring vertically downward and capable of aligning with the opening of the inner barrel. The camera, distance sensor, first drive device, and second drive device are each electrically connected to the main control board.

[0010] Furthermore, the first driving device is a steering gear installed on the lower side of the identification platform. The gate is fan-shaped, the gate near the center is installed on the output shaft of the steering gear, and the gate away from the center is slidably installed in a chute on the lower side of the identification platform.

[0011] Furthermore, the rotating platform is mounted on the outer cylinder through a thrust bearing. The second driving device is a two-phase stepping motor, which coaxially drives the rotating platform to rotate.

[0012] Furthermore, a solar panel is installed on the outer side of the upper cover, and the solar panel is electrically connected to the main control board.

[0013] Furthermore, a boss for positioning the inner barrel is provided on the upper side of the rotating table, and a first positioning groove corresponding to the boss is provided on the bottom of the inner barrel.

[0014] Furthermore, a column is provided in the middle of the rotating platform, a positioning rod for positioning the inner barrel is provided on the column, and a second positioning slot corresponding to the positioning rod is provided on the side wall of the inner barrel.

[0015] Furthermore, a display screen is installed on the outside of the outer cylinder, and the display screen is electrically connected to the main control board.

[0016] Furthermore, a side door for taking out and placing the inner barrel is provided on the outer barrel.

[0017] Compared with the prior art, the present invention has the following beneficial effects.

[0018] 1. The present invention drives the rotating table to rotate through the second driving device, which can drive multiple inner barrels to rotate in sequence to the bottom of the drop-in port. At this time, the gate is driven to rotate by the first driving device, so that the garbage above can be accurately dropped from the drop-in port into the inner barrel below. Compared with the traditional smart classification trash cans on the market that place the inner barrels in rows, the classification mechanism is simple and the space utilization is more reasonable.

[0019] 2. The present invention is powered by solar panels. Compared with traditional trash cans that rely on mains electricity or have no intelligent energy-saving design, this power supply mode makes full use of solar energy, a clean energy, reduces dependence on traditional energy, achieves energy-saving and environmental protection goals, reduces operating costs, and meets the demand of modern society for environmentally friendly and energy-saving products.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-8 As shown, an intelligent classification trash can has an outer cylinder 1 and an upper cover 2 with a drop-in port 201. The identification platform 3 is arranged on the upper side of the outer cylinder 1 and located on the lower side of the upper cover 2, and has a drop-in port 301. The gate 302 is set on the lower side of the identification platform 3 and can be opened and closed by the first driving device 4. The rotating platform 5 can be horizontally rotatably installed on the lower side of the outer cylinder 1. A plurality of inner barrels 501 are placed on the rotating platform 5, and the barrel mouths of the inner barrels 501 can be aligned with the drop-in port 301. The second driving device 6 is installed on the inner side of the outer cylinder 1, and is used to drive the rotating platform 5 to rotate.

[0024] After the garbage is thrown into the drop-in port 201, it falls onto the identification platform 3. The curved inner wall of the identification platform 3 is used to guide the garbage to fall into the gate 302 for easy classification. After the classification is completed, the second driving device 6 drives the rotating platform 5 to rotate, driving the barrel mouth of the corresponding inner barrel 501 to be aligned to the bottom of the drop-in port 301. Then, the gate 302 is driven to rotate by the first driving device 4. The side wall of the drop-in port 301 blocks the garbage. When the drop-in port 301 is turned open, the garbage can fall accurately from the drop-in port 301 into the inner barrel 501 below. After the garbage is thrown in, the first driving device 4 drives the gate 302 to close, which can reduce the smell emitted by the garbage and is more conducive to the beautification of the urban environment.

[0025] Preferably, the main control board 7 is mounted on the inside of the upper cover 2. A camera 701 is mounted on the top of the inner side of the upper cover 2 and is used to collect images of garbage on the upper side of the identification platform 3. A distance sensor 702 is mounted on the lower side of the identification platform 3, measuring vertically downward and aligned with the opening of the inner tub 501. The camera 701, distance sensor 702, first drive device 4, and second drive device 6 are each electrically connected to the main control board 7.

[0026] The distance measuring sensor 702 and the first driving device 4 are installed on the lower side of the identification platform 3 to maintain the distance measuring sensor 702 and the first driving device 4 in a clean state and extend their service life.

[0027] When garbage falls on the gate 302, the camera 701 is used to capture images and automatically identify and classify them, so that the corresponding garbage falls into the corresponding inner bucket 501, thus achieving garbage classification. The distance sensor 702 is used to monitor the garbage in the inner bucket 501. When the garbage is full, a full bin message is displayed, facilitating timely garbage cleaning and maintenance.

[0028] Camera 701 uses an OpenMV4H7Plus camera as its image acquisition device. This camera offers a unique advantage: its built-in neural network module is compatible with the TensorFlow Lite Micro framework. This compatibility makes the device extremely efficient when running deep learning models, significantly improving the accuracy of image recognition and feature extraction. During the garbage identification process, Camera 701 can quickly and accurately capture images of garbage, providing a high-quality data foundation for subsequent classification processing.

[0029] The model trained through Edge Impulse transfer learning can accurately distinguish at least four different types of waste, with an overall classification accuracy of 85%. This metric means that in a large number of waste delivery tests, the system can successfully place waste into the corresponding inner bin 501 with a very high rate, effectively avoiding the problem of waste mixing caused by classification errors and greatly improving the efficiency of waste recycling.

[0030] Preferably, the main control board 7 uses an STM32F103C8T6 chip. This chip has stable performance and powerful functionality, meeting the data processing and control requirements of this product. A timer outputs a PWM square wave to drive the second drive device 6. When the OpenMV camera identifies four different types of garbage, it transmits the classification results to the main control board 7 via serial communication. The main control board 7 changes the PWM duty cycle based on the received information, thereby precisely controlling the rotation angle of the second drive device 6.

[0031] Preferably, distance sensor 702 is an ultrasonic distance sensor, which uses ultrasonic ranging technology to detect the volume of the garbage in inner bucket 501. When the garbage pile reaches a height that matches the height of the ultrasonic generator, it indicates that the garbage is full. If the ultrasonically measured distance is less than the inner diameter of the bucket, the system will interrupt the MCU and promptly notify the system of the full bin. This full bin information can also be transmitted to a central management device via a wireless network to alert management personnel, facilitating timely garbage removal and maintenance.

[0032] Preferably, the first driving device 4 is a steering gear installed on the lower side of the identification platform 3. The gate 302 is fan-shaped, and the gate 302 is installed on the output shaft of the steering gear near the center of the circle, and the side of the gate 302 away from the center of the circle is slidably installed in the slide groove 303 on the lower side of the identification platform 3.

[0033] The gate 302 is driven to rotate by the first driving device 4 to achieve the purpose of opening and closing the landing entrance 301, and the setting of the slide groove 303 can provide stable support for the gate 302, and will not affect the output shaft of the first driving device 4 even when bearing heavier garbage.

[0034] Preferably, the rotating platform 5 is mounted on the outer cylinder 1 via a thrust bearing 502. The second driving device 6 is a two-phase stepping motor, which coaxially drives the rotating platform 5 to rotate.

[0035] Driven by a two-phase stepper motor, the rotating platform 5 can rotate through 360° or more. This high degree of freedom in rotational control ensures that the inner bucket 501 is precisely positioned to the appropriate waste type, ensuring accurate waste placement. Even with frequent use and long-term operation, it maintains stable performance, providing reliable mechanical support for the entire waste sorting process.

[0036] A base is provided on the outside of the two-phase stepper motor. The base is integrated with the outer barrel 1 and is used to fix and protect the two-phase stepper motor and bear the gravity of the rotating platform 5 and the inner barrel 501.

[0037] Preferably, a solar panel 703 is installed on the outer side of the upper cover 2 , and the solar panel 703 is electrically connected to the main control board 7 .

[0038] Power is supplied by solar panels 703. Compared with traditional trash cans that rely on mains electricity or have no intelligent energy-saving design, this power supply mode makes full use of solar energy, a clean energy, reduces dependence on traditional energy, achieves energy conservation and environmental protection goals, reduces operating costs, and meets the demand of modern society for environmentally friendly and energy-saving products.

[0039] Furthermore, solar panel 703 can be used in conjunction with an intelligent sensing system (not shown). After detecting that no one is in front of the bin for 10 minutes, the system enters standby mode and enters a low-power state. This low-power mode significantly reduces energy consumption during long-term operation, improves battery life, and ensures power supply. The intelligent sensing system can be a visual monitoring camera or an infrared monitoring sensor, which can detect whether there is a person in front of the intelligent sorting trash bin.

[0040] Preferably, a boss 503 for positioning the inner barrel 501 is provided on the upper side of the rotating table 5 , and a first positioning slot 504 corresponding to the boss 503 is provided on the bottom of the inner barrel 501 .

[0041] By snapping the first positioning slot 504 at the bottom of the inner barrel 501 onto the boss 503 , the purpose of positioning can be achieved, ensuring that the barrel opening of the inner barrel 501 can accurately correspond to the drop-in opening 301 .

[0042] Preferably, a column 505 is provided in the middle of the rotating platform 5, and a positioning rod 506 for positioning the inner barrel 501 is provided on the column 505, and a second positioning slot 507 corresponding to the positioning rod 506 is provided on the side wall of the inner barrel 501.

[0043] After the positioning rod 506 is inserted into the second positioning slot 507 on the inner barrel 501, the positioning function of the boss 503 and the first positioning slot 504 can be combined to improve the installation stability of the inner barrel 501 and prevent the inner barrel 501 from falling during the rotation of the rotating platform 5.

[0044] It is worth noting that the size of the second positioning slot 507 is slightly larger than the diameter of the positioning rod 506 , ensuring that the boss 503 can be inserted into the first positioning slot 504 while the positioning rod 506 is inserted into the second positioning slot 507 .

[0045] Preferably, a display screen 101 is installed on the outside of the outer cylinder 1 , and the display screen 101 is electrically connected to the main control board 7 .

[0046] Through IIC communication, garbage classification information can be displayed on display screen 101, while advertisements and environmental awareness can also be played. This design offers significant added value compared to traditional trash cans, which simply serve as garbage collection containers. On the one hand, clearly displaying the types of garbage to be placed helps increase user awareness and participation in waste sorting. On the other hand, the advertising function provides opportunities for commercial applications, while promoting environmental awareness also enhances public awareness, making the trash can a multifunctional device that integrates garbage disposal, information transmission, and environmental awareness.

[0047] Preferably, the outer cylinder 1 is provided with a side door 102 for taking in and placing the inner barrel 501 .

[0048] Facilitate timely cleaning and maintenance of garbage.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
