[0039] Among them, under the action of the driving member 14, when the top cover 11 is opened, the scraper 13 moves outward with the top cover 11 relative to the collecting port 12, so that the collecting port 12 is exposed. When the top cover 11 is closed, the scraper 13 moves inward with the top cover 11 relative to the collecting port 12 and completes the scraping operation, so that the collecting port 12 is covered.

[0040] The utility model is equipped with a scraper and a single driving component inside the trash bin, and the driving component simultaneously controls the opening and closing of the top cover and the movement of the scraper. When the top cover is opened, the scraper moves outward to expose the collection port. When the top cover is closed, the scraper moves inward to complete the scraping and cover the collection port. This design uses a single driving component to replace multiple driving components, simplifies the structure, reduces costs, and improves the reliability of the system and the convenience of maintenance.

[0041] In this embodiment, a top cover 11 and a collecting port 12 are installed on the upper part of the trash can body 1. The collecting port 12 can also be designed as a part of the top cover 11. The collecting port 12 is located in the center or around the top cover 11, or can be located on the side of the trash can body 1.

[0042] In this embodiment, the top cover 11 can be connected to the trash can body 1 through the following mechanisms to achieve the action of opening and closing:

[0044] 2. Slide rail system: The top cover 11 can slide through the slide rails installed on both sides of the trash can, so that the top cover can slide upward or slide downward to provide a smooth movement trajectory;

[0045] 3. Rotation axis: The top cover 11 can be connected to the trash can body 1 through a central rotation axis, so that the top cover can be rotated around the axis to open or close;

[0046] 4. Telescopic arms: A set of telescopic arms is used to connect the top cover 11 to the trash bin body 1. The telescopic arms can be hydraulic or pneumatic, allowing the top cover to rise or fall in the vertical direction;

[0047] 5. Magnetic connection: The top cover 11 may be connected to the trash can body 1 through a magnetic mechanism, and magnetic locking or unlocking is used to control the opening and closing of the top cover;

[0048] 6. Cable system: The top cover 11 can be connected to the trash can body 1 by cables. This design allows the top cover to be pulled up when opening or lowered when closing. The scraper 13 can also be connected to the top cover by a cable system, so that when the top cover moves, the scraper performs a corresponding lifting action;

[0049] 7. Gear mechanism: A gear system is installed between the top cover 11 and the trash can body 1, so that the top cover can be opened or closed by rotating the gears. The scraper 13 can also be synchronized with the top cover 11 through a small gear system to ensure that its position is accurately adjusted with the movement of the top cover;

[0050] 8. Elastic connection: Use a connector made of rubber or other elastic materials to connect the top cover 11 to the trash can body 1. This elastic connection can absorb the vibration generated during operation and increase the service life. The scraper 13 can be fixed under the top cover using similar elastic materials to provide sufficient flexibility to adapt to different loads;

[0051] 9. Slide rod support: The top cover 11 can be installed on the trash bin body 1 through a slide rod, which allows the top cover to slide open and close smoothly. The scraper 13 also maintains the correct movement trajectory through the slide rod connected to the top cover 11 to ensure cleaning efficiency;

[0052] 10. Hydraulic or pneumatic push rod: The top cover 11 and the scraper 13 can be automatically controlled by hydraulic or pneumatic push rods. This system allows remote control of the opening and closing of the top cover and the movement of the scraper, and is suitable for garbage disposal systems that require frequent or remote operations;

[0053] In this embodiment, the scraper 13 can achieve the scraping action through the following mechanisms:

[0054] 1. Guide rail fixation: The scraper 13 can move along the guide rail at the bottom of the top cover 11 and is closely combined with the guide rail to ensure its stable movement;

[0055] 2. Articulated connection: The scraper 13 is connected to the top cover 11 through a hinge point, so that the scraper can swing accordingly with the opening and closing of the top cover;

[0056] 3. Slider and slot connection: The scraper 13 is installed in the slot below the top cover 11 through a slider device. The slider can slide freely in the slot and move with the top cover;

[0057] 4. Spring: The scraper 13 is connected to the top cover 11 through a spring. The spring provides the necessary tension to keep the scraper working under appropriate pressure;

[0058] In this embodiment, the shape of the top cover 11 includes but is not limited to:

[0059] Flat top design provides a flat surface that fits most standard dumpster configurations. This design is simple, easy to manufacture, and facilitates stacking, making it suitable for commercial and residential environments;

[0060] The dome design is more suitable for outdoor use, especially in areas with heavy rain and snow. The dome can effectively prevent water and snow from accumulating on the top cover, reducing the structural burden;

[0061] The slope design can help reduce wind resistance, especially in windy areas to prevent the top cover from being blown away by the wind. In addition, the slope helps to naturally guide water and reduce water accumulation.

[0062] In this embodiment, the manufacturing materials of the top cover 11 include but are not limited to:

[0063] Stainless steel: Very suitable for the top cover material because it is corrosion-resistant, wear-resistant, and strong. Suitable for long-term outdoor use, although the cost is relatively high;

[0064] High-density polyethylene (HDPE): Lightweight and low-cost, with good chemical and impact resistance. This material is also easy to process and is often used in household or commercial waste bins;

[0065] Composite materials, such as fiberglass reinforced plastic (FRP): combine the lightness of plastic with the strength of metal, have excellent aging resistance and are well suited for long-term exposure to harsh environments.

[0066] In this embodiment, the shape of the scraper 13 includes but is not limited to:

[0067] Straight type: suitable for most flat or slightly curved inner walls of trash bins, providing efficient scraping effect;

[0068] Curved type: better adapt to the inner wall of circular or polygonal trash bins, increase the contact area between the scraper and the inner wall of the trash bin, and thus improve the scraping efficiency. Adjustable angle type: through the mechanical adjustment mechanism, the scraper's attack angle can be adjusted according to different garbage types and inner wall conditions, increasing its flexibility and use efficiency.

[0069] In this embodiment, the manufacturing materials of the scraper 13 include but are not limited to:

[0070] Hardened steel: Ideal for use in scrapers as it provides the necessary hardness and durability, especially for scraping harder substances;

[0071] Silicone: It provides good flexibility and temperature resistance, and is especially suitable for environments with large temperature changes. At the same time, the softness of silicone can reduce the wear on the inner wall of the trash can;

[0072] Polyurethane: Providing a good balance between hardness and flexibility, polyurethane scrapers are wear-resistant and not easily deformed, making them suitable for frequent use.

[0073] In this embodiment, the driving component 14 is an oil cylinder. The driving component 14 is the core component in the scraper mechanism of the garbage bin top cover and is responsible for the output and transmission of power. The driving component 14 includes but is not limited to: an electric motor, a servo motor, a stepper motor, a hydraulic system, a pneumatic system, a mechanical spring system, etc.

[0074] Optionally, a transmission member 15 is further included, and the driving member 14 is connected to the transmission member 15 . The driving member 14 controls the movement of the top cover 11 and the scraper 13 through the transmission member 15 .

[0075] In this embodiment, the following solutions can be roughly divided into, including but not limited to:

[0076] Solution 1: The driving member is connected to the transmission member, and the transmission member is connected to the top plate and the scraper;

[0077] In this solution, the driving member 14 (such as an electric motor) is directly connected to the transmission member 15 (such as a connecting rod or a gear system), and the transmission member 15 is responsible for transmitting the power of the driving member to the top plate 11 and the scraper 13 at the same time. This arrangement allows the top plate 11 and the scraper 13 to move in coordination through the same transmission mechanism, thereby ensuring the synchronous execution of the opening and closing action and the scraping function. For example, when the top plate 11 is driven to open to put garbage, the scraper 13 moves outward at the same time to expand the collection port and clean the interface area.

[0078] Solution 2: The driving member is connected to the transmission member, the driving member is also connected to the top plate, and the transmission member is further connected to the scraper;

[0079] In this configuration, the driving member 14 is not only connected to the transmission member 15, but also directly connected to the top plate 11. This design allows the top plate 11 to obtain more direct power input and achieve fast and precise opening and closing control. The transmission member 15 is specifically used to control the movement of the scraper 13. This separate control strategy allows for more precise adjustment of the opening and closing speed and force of the top plate, while ensuring that the scraper 13 can perform effective cleaning work after the top plate 11 is fully opened.

[0080] Solution 3: The driving member is connected to the transmission member, the driving member is also connected to the scraper, and the transmission member is further connected to the top plate;

[0081] In this solution, the driving member 14 is also connected to the transmission member 15, but the driving member is also directly connected to the scraper 13. This arrangement allows the scraper 13 to directly receive a stronger driving force, thereby improving the scraping efficiency, which is particularly effective when a large amount of or heavy garbage needs to be cleaned. The transmission member 15 is responsible for the opening and closing of the top plate 11, ensuring that the movement of the top plate and the activity of the scraper do not interfere with each other, thereby optimizing the operating process and safety.

[0082] The above solutions are adjusted on the basis of the big solution to adapt to different operational requirements and specific usage scenarios, and to improve the flexibility and efficiency of the system.

[0083] Optionally, the top cover 11 is rotatably connected to the trash bin body 1, and its connection fulcrum is the third connecting part 4. The transmission member 15 is rotatably connected to the top cover 11 and the scraper 13. The driving member 14 drives the top cover 11 to rotate along the third connecting part 4 through the transmission member 15, thereby driving the scraper 13 to rotate.

[0084] In this embodiment, by adopting a rotating connection, the top cover 11 and the scraper 13 can achieve smooth and synchronous movement. This mechanism ensures the consistency and efficiency of the operation. In addition, the rotating connection reduces friction and wear between the top cover 11 and the scraper 13 during the opening and closing process, thereby extending the service life of the equipment.

[0086] Among them, the driving member 14 drives the first connecting rod 151 to rotate at the first connecting part 2, the first connecting rod 151 drives the second connecting rod 152 to move along the driving direction, and the movement of the second connecting rod 152 drives the scraper 13 connected thereto to rotate at the second connecting part 3 and move toward the inside of the trash can. The movement of the scraper 13 drives the fourth connecting rod 154 to move downward through the connection with the fourth connecting rod 154, and finally the action of the fourth connecting rod 154 drives the top cover 11 to rotate downward along the third connecting part 4.

[0087] In this embodiment, efficient coordinated movement of the top cover and the scraper is achieved through a sophisticated connecting rod system. The first connecting rod 151 started by the driving member 14 rotates at the first connecting part 2 to start the entire mechanical sequence. This design utilizes the transmission efficiency of mechanical force. The rotation of the first connecting rod 151 directly drives the second connecting rod 152 to move in a predetermined direction, thereby driving the scraper 13 connected to it for rotation. The scraper 13 rotates at the second connecting part 3 and moves toward the inside of the garbage bin, which not only improves the thoroughness of garbage cleaning, but also enhances the overall mechanical efficiency. The movement of the scraper is further connected with the fourth connecting rod 154 to achieve coordinated downward movement of the top cover 11. This linkage design of the connecting rod makes the opening and closing of the top cover and the movement of the scraper perfectly synchronized, ensuring smooth and safe operation. The advantage of this system lies in the simplicity of its mechanical connection and the effective transmission of force. Through optimization based on geometric and mechanical principles, efficient force transmission and conversion between the connecting rods are achieved, greatly enhancing the reliability and durability of the system.

[0088] Preferably, the connecting rod may use carbon fiber composite materials instead of traditional steel. The carbon fiber material is not only light in weight but also has high strength and good corrosion resistance, and is suitable for complex mechanical movement environments.

The base 71 provides stable support, while the rotating interface 72 ensures the synchronous rotation of the top cover and the scraper 13, thereby improving the reliability and operational efficiency of the overall system.

[0094] Preferably, the base 71 and the rotation interface 72 can be replaced by a slide rail system to allow the top cover 11 to move smoothly in a straight line instead of rotating. In addition, the rotation interface 72 can be replaced by a spherical joint.

[0097] In this embodiment, the stability and durability of the system are improved by introducing gaskets 8 in each connection part. The gaskets 8 are located between each connection part and the element connected thereto, effectively reducing wear and vibration and extending the service life of the equipment.

[0098] Preferably, the gasket can be replaced with an elastic washer or a self-lubricating bearing.
