Abstract
Description
Technical Field
[0001] This utility model relates to the field of household goods technology, and in particular to a double-lid trash can. Background Technology
[0002] With the rapid pace of urbanization and increasingly higher demands for quality of life, trash cans, as an indispensable infrastructure for maintaining public hygiene, play a crucial role in creating a clean and healthy living space. Double-lid trash cans, with their advantages over single-lid trash cans in terms of space adaptability and disposal flexibility, have found some application in homes and public places.
[0003] However, existing double-lid trash cans have a significant drawback in their operation—they rely on users to manually lift the lid. The trash cans accumulate various types of garbage, making them a breeding ground for bacteria, viruses, and other pathogens. When manually lifting the lid, hands come into direct contact with the lid, easily becoming contaminated with these pathogens, leading to a range of health problems and impacting daily life and work.
[0004] Therefore, improvements to existing technologies are necessary. Utility Model Content
[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a double-lid trash can that can solve the problem that existing double-lid trash cans rely on users to manually open the lid, which leads to the easy contamination of pathogens by hands when touching the trash can lid, causing health problems and affecting daily life and work.
[0006] A double-lid trash can according to this utility model includes a can body, a receiving box, an opening and closing mechanism, and a sealing lid assembly. The top of the can body has a first opening. The receiving box is connected to the inner wall of the can body. The opening and closing mechanism is housed in the receiving box and includes a motor and a connecting rod assembly. The sealing lid assembly includes a first sealing lid and a second sealing lid, which are located at the first opening. The output end of the motor is connected to the first sealing lid and hinged to the first end of the connecting rod assembly. The second end of the connecting rod assembly is hinged to the second sealing lid. When the motor starts in the forward direction, the first sealing lid is driven by the motor to flip upward, and simultaneously the second sealing lid is driven to flip upward synchronously through the connecting rod assembly, so as to open the first opening. When the motor starts in the reverse direction, the first sealing lid is driven by the motor to flip downward, and simultaneously the second sealing lid is driven to flip downward synchronously through the connecting rod assembly, so as to close the first opening.
[0007] According to this utility model, a double-lid trash can has at least the following beneficial effects: When it is necessary to open the first opening of the trash can to dispose of trash, the user only needs to start the motor to make it run in the forward direction. The motor output end starts to move, and since the motor output end is connected to the first sealing cover, the first sealing cover is driven upward by the motor. At the same time, the first end of the connecting rod assembly hinged to the motor output end also moves accordingly, and the connecting rod assembly undergoes corresponding angle and position changes, thereby driving the second sealing cover hinged to its second end to flip upward synchronously. Under the combined upward flipping action of the first and second sealing covers, the first opening at the top of the can gradually opens, and the user can dispose of trash. When the trash is disposed of, the user starts the motor to make it run in the reverse direction. The motor output end moves in the reverse direction, and the first sealing cover begins to flip downward under the drive of the motor. At this time, the connecting rod assembly changes its state with the reverse movement of the motor output end, and through the transmission action of the connecting rod assembly, drives the second sealing cover to flip downward synchronously. As the first and second sealing covers continue to flip downward, the first opening at the top of the can gradually closes, and the trash can returns to a sealed state. This utility model of a double-lid trash can uses a motor to automatically open and close the sealing lid, eliminating the need for users to directly touch the trash can lid. This fundamentally cuts off the contact route between the hands and pathogens, greatly reducing the risk of health problems caused by contact with pathogens.

[0034] Reference Figures 1-7According to this utility model, a double-lid trash can includes a bin body, a receiving box 20, an opening and closing mechanism, and a sealing lid assembly. The top of the bin body has a first opening. The receiving box 20 is connected to the inner wall of the bin body. The opening and closing mechanism is housed in the receiving box 20 and includes a motor 23 and a connecting rod assembly. The sealing lid assembly includes a first sealing lid 12 and a second sealing lid 13, which are located at the first opening. The output end of the motor 23 is connected to the first sealing lid 12 and hinged to the first end of the connecting rod assembly. The second end of the connecting rod assembly is hinged to the second sealing lid 13. When the motor 23 starts in the forward direction, the first sealing lid 12 is driven by the motor 23 to flip upward, and at the same time, the second sealing lid 13 is driven to flip upward synchronously through the connecting rod assembly, so as to open the first opening. When the motor 23 starts in the reverse direction, the first sealing lid 12 is driven by the motor 23 to flip downward, and at the same time, the second sealing lid 13 is driven to flip downward synchronously through the connecting rod assembly, so as to close the first opening.
[0035] According to some embodiments of the present invention, the first side of the first sealing cover 12 is rotatably connected to the receiving box 20 via a first rotating shaft, the first side of the second sealing cover 13 is rotatably connected to the receiving box 20 via a second rotating shaft, and the second side of the first sealing cover 12 and the second side of the second sealing cover 13 are respectively rotatably connected to the inner wall of the barrel via a third rotating shaft and a fourth rotating shaft.
[0036] When it's time to open the first opening of the trash can to dispose of trash, the user simply starts motor 23 to rotate it forward. The output of motor 23 begins to move, and since the output of motor 23 is connected to the first sealing cover 12, the first sealing cover 12 is driven upward by motor 23. Simultaneously, the first end of the connecting rod assembly hinged to the output of motor 23 also moves, causing a corresponding change in angle and position, which in turn drives the second sealing cover 13, hinged to its second end, to rotate upward synchronously. Under the combined upward rotation of the first sealing cover 12 and the second sealing cover 13, the first opening at the top of the can gradually opens, allowing the user to dispose of trash. After disposing of trash, the user starts motor 23 to rotate it in reverse. The output of motor 23 rotates in reverse, and the first sealing cover 12 begins to rotate downward under the drive of motor 23. At this time, the connecting rod assembly changes its state with the reverse movement of the output of motor 23, and through the transmission action of the connecting rod assembly, drives the second sealing cover 13 to rotate downward synchronously. As the first sealing cover 12 and the second sealing cover 13 continue to rotate downward, the first opening at the top of the can gradually closes, and the trash can returns to a sealed state. The double-lid trash can of this invention uses a motor 23 to automatically open and close the sealed lid. Users do not need to directly touch the trash can lid with their hands, which fundamentally cuts off the contact route between the hands and pathogens, and greatly reduces the risk of health problems caused by contact with pathogens.
[0037] According to some embodiments of the present invention, the double-lid trash can also includes a fixed base 22, a motor 23 is detachably connected to the fixed base 22, and the fixed base 22 is detachably connected to the container 20.
[0038] According to some embodiments of the present invention, the bottom of the housing 20 is connected to a first fixing post 21, the first fixing post 21 has a first threaded hole, the motor 23 has a second opening, the fixing seat 22 has a second threaded hole corresponding to the position of the second opening and a first opening corresponding to the position of the first threaded hole, the first bolt passes through the first opening and is threaded to the first threaded hole to lock the fixing seat 22 to the housing 20, and the second bolt passes through the second opening and is threaded to the second threaded hole to lock the motor 23 to the fixing seat 22.
[0039] When assembling the double-lid trash can, align the first opening on the mounting base 22 with the first threaded hole. Then, use the first bolt, passing it through the first opening, and gradually screw the threaded end of the first bolt into the first threaded hole of the first fixing post 21 to complete the locking connection between the mounting base 22 and the container 20. Next, place the motor 23 on the mounting base 22, aligning the second opening on the motor 23 with the corresponding second threaded hole on the mounting base 22. Then, use the second bolt, passing it through the second opening from the side of the motor 23 away from the mounting base 22, and screw the threaded end of the second bolt into the second threaded hole of the mounting base 22 to achieve the locking connection between the motor 23 and the mounting base 22.
[0040] According to some embodiments of the present invention, the bin body includes a frame 10 and a bottom plate. The top of the frame 10 is provided with a first opening, and the bottom of the frame 10 is provided with a second opening. The bottom plate is detachably connected to the bottom of the frame 10 to seal the second opening. The frame 10 and the bottom plate together enclose and form a holding space 11 for placing garbage.
[0041] In traditional trash can designs, if the bottom structure malfunctions, the entire trash can (including the frame 10 and the bottom plate) may need to be scrapped. However, in this invention, the frame 10 and the bottom plate are separable. When the bottom plate is damaged, only the bottom plate needs to be replaced, eliminating the need to discard the relatively intact and costly frame 10. This significantly reduces material waste and saves on the cost of replacing the entire unit.
[0042] The opening and closing mechanism includes a first embodiment and a second embodiment, which will be described in detail below.
[0043] First embodiment:
[0044] Reference Figures 4-5According to some embodiments of the present invention, a first through hole is provided on the side wall of the receiving box 20, and a first connecting shaft 14 is provided on the side of the first sealing cover 12 near the receiving box 20. The first connecting shaft 14 passes through the first through hole, and a driven gear 28 is fixedly connected to one end of the first connecting shaft 14 located in the receiving box 20. A driving gear 27 is provided at the output end of the motor 23. The driving gear 27 meshes with the driven gear 28 to drive the first sealing cover 12 to rotate.
[0045] The side wall of the housing 20 is provided with a second through hole, and the second sealing cover 13 is provided with a second connecting shaft 15 on the side near the housing 20. The second connecting shaft 15 passes through the second through hole, and the connecting rod assembly is hinged to the output end of the motor 23. The motor 23 drives the second sealing cover 13 to rotate through the connecting rod assembly.
[0046] According to some embodiments of the present invention, the linkage assembly includes a first linkage 30, a second linkage 31, and a third linkage 32. The first end of the first linkage 30 is hinged to the output end of the motor 23, and the first end of the third linkage 32 is hinged to the second connecting shaft 15. The two ends of the second linkage 31 are respectively provided with a first fixed shaft and a second fixed shaft. The first fixed shaft passes through the second end of the first linkage 30, and the first linkage 30 is rotatably connected to the first fixed shaft. The second fixed shaft passes through the second end of the third linkage 32, and the third linkage 32 is rotatably connected to the second fixed shaft.
[0047] After the motor 23 starts in the forward direction, its output end begins to rotate, driving the drive gear 27 to rotate clockwise. Since the drive gear 27 meshes with the driven gear 28, the rotational motion of the drive gear 27 is transmitted to the driven gear 28 through gear meshing, causing the driven gear 28 to rotate counterclockwise. The driven gear 28 is fixed on the first connecting shaft 14, so the rotation of the driven gear 28 drives the first connecting shaft 14 to rotate within the first through hole. The first connecting shaft 14 is also connected to the first sealing cover 12, thereby driving the first sealing cover 12 to rotate upward around the axis of the first connecting shaft 14, thus realizing the opening action of the first sealing cover 12. The third connecting rod 32 rotates clockwise, thereby driving the second sealing cover 13 to rotate upward around the axis of the second connecting shaft 15, thus realizing the opening action of the second sealing cover 13, at which point garbage can be disposed of. After garbage is disposed of, the drive motor 23 rotates in the reverse direction. At this time, the first sealing cover 12 rotates clockwise, and the second sealing cover 13 rotates counterclockwise, closing the first opening with the first sealing cover 12 and the second sealing cover 13. The double-lid trash can of this invention uses a motor 23 to automatically open and close the sealed lid. Users do not need to directly touch the trash can lid with their hands, which fundamentally cuts off the contact route between the hands and pathogens, and greatly reduces the risk of health problems caused by contact with pathogens.
[0048] According to some embodiments of the present invention, the double-lid trash can also includes a fixing plate 25, and a second fixing post 24 is connected to the bottom of the receiving box 20. The second fixing post 24 has a third threaded hole, and the fixing plate 25 has a third opening at the position corresponding to the third threaded hole. A third bolt passes through the third opening and is threaded to the third threaded hole to lock the fixing plate 25 to the receiving box 20. The first end of the third connecting rod 32 has a locking block 33 on the side facing the fixing plate 25, and the fixing plate 25 has a locking groove at the position corresponding to the locking block 33. The locking block 33 is embedded in the locking groove.
[0049] During the assembly of the double-lid trash can, the third opening on the fixing plate 25 is aligned with the third threaded hole on the second fixing post 24 at the bottom of the receiving box 20. Then, the third bolt is passed through the third opening from the side of the fixing plate 25 away from the bottom of the receiving box 20 and gradually screwed into the third threaded hole, thereby firmly locking the fixing plate 25 onto the receiving box 20. Since the first end of the third connecting rod 32 is provided with a locking block 33 facing the fixing plate 25, and the fixing plate 25 is provided with a locking groove at the position of the locking block 33, the cooperation between the locking block 33 and the locking groove plays a role in positioning and limiting, ensuring that the third connecting rod 32 maintains a stable position and posture during movement, so that the second sealing cover 13 can open and close according to the predetermined trajectory and angle.
[0050] Second embodiment:
[0051] Reference Figures 6-7 According to some embodiments of the present invention, a first through hole is provided on the side wall of the receiving box 20, a first connecting shaft 14 is provided on the side of the first sealing cover 12 near the receiving box 20, the first connecting shaft 14 passes through the first through hole, a limiting hole is provided at one end of the first connecting shaft 14 located in the receiving box 20, a limiting block 26 is fixedly connected to the output end of the motor 23, the limiting block 26 is inserted into the limiting hole and is interference-fitted with the limiting hole, so as to drive the first sealing cover 12 to rotate through the motor 23.
[0052] The side wall of the housing 20 is provided with a second through hole, and the second sealing cover 13 is provided with a second connecting shaft 15 on the side near the housing 20. The second connecting shaft 15 passes through the second through hole, and the connecting rod assembly is hinged to the output end of the motor 23. The motor 23 drives the second sealing cover 13 to rotate through the connecting rod assembly.
[0053] According to some embodiments of the present invention, the linkage assembly includes a first linkage 30, a second linkage 31, and a third linkage 32. The first end of the first linkage 30 is hinged to the output end of the motor 23, and the first end of the third linkage 32 is hinged to the second connecting shaft 15. The two ends of the second linkage 31 are respectively provided with a first fixed shaft and a second fixed shaft. The first fixed shaft passes through the second end of the first linkage 30, and the first linkage 30 is rotatably connected to the first fixed shaft. The second fixed shaft passes through the second end of the third linkage 32, and the third linkage 32 is rotatably connected to the second fixed shaft.
[0054] When motor 23 starts forward, its output end begins to rotate clockwise. Since a limiting block 26 is fixedly connected to the output end of motor 23, and a limiting hole is provided at one end of the first connecting shaft 14 inside the receiving box 20, the limiting block 26 is inserted into and interference-fitted with the limiting hole. Therefore, the rotational motion of the output end of motor 23 is directly transmitted to the first connecting shaft 14. As the first connecting shaft 14 rotates, the first sealing cover 12 flips upward around the axis of the first connecting shaft 14, thus opening the first sealing cover 12. The first end of the first connecting rod is hinged to the output end of motor 23. The first connecting rod rotates clockwise. The first end of the third connecting rod 32 is hinged to the second connecting shaft 15. The second ends of both the first and third connecting rods are hinged to the second connecting rod. The clockwise rotation of the first connecting rod pushes the third connecting rod to rotate counterclockwise, thus opening the second sealing cover 13, allowing for waste disposal. After the garbage is disposed of, the drive motor 23 rotates in reverse. At this time, the first sealing cover 12 rotates counterclockwise, and the second sealing cover 13 rotates clockwise, closing the first opening. The double-lid garbage bin of this utility model achieves automatic opening and closing of the sealing covers through the drive of the motor 23. Users do not need to directly touch the garbage bin lid with their hands, fundamentally cutting off the contact route between the hands and pathogens, and greatly reducing the risk of health problems caused by contact with pathogens.
[0055] According to some embodiments of the present invention, the double-lid trash can also includes a fixing plate 25, and a second fixing post 24 is connected to the bottom of the receiving box 20. The second fixing post 24 has a third threaded hole, and the fixing plate 25 has a third opening at the position corresponding to the third threaded hole. A third bolt passes through the third opening and is threaded to the third threaded hole to lock the fixing plate 25 to the receiving box 20. The first end of the third connecting rod 32 has a locking block 33 on the side facing the fixing plate 25, and the fixing plate 25 has a locking groove at the position corresponding to the locking block 33. The locking block 33 is embedded in the locking groove.
[0056] During the assembly of the double-lid trash can, the third opening on the fixing plate 25 is aligned with the third threaded hole on the second fixing post 24 at the bottom of the receiving box 20. Then, the third bolt is passed through the third opening from the side of the fixing plate 25 away from the bottom of the receiving box 20 and gradually screwed into the third threaded hole, thereby firmly locking the fixing plate 25 onto the receiving box 20. Since the first end of the third connecting rod 32 is provided with a locking block 33 facing the fixing plate 25, and the fixing plate 25 is provided with a locking groove at the position of the locking block 33, the cooperation between the locking block 33 and the locking groove plays a role in positioning and limiting, ensuring that the third connecting rod 32 maintains a stable position and posture during movement, so that the second sealing cover 13 can open and close according to the predetermined trajectory and angle.
[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
