Description

A lid opening structure for a smart trash can and a smart trash can Technical Field

[0001] This invention relates to trash cans, and more specifically to an opening structure for an intelligent trash can and an intelligent trash can. Background Technology

[0002] Some smart trash cans have been proposed in the prior art. For example, the invention application with publication number CN 108584238 A discloses a trash bag packing mechanism and a smart trash can, and the utility model patent with authorization announcement number CN 210012170U discloses a trash bag packing mechanism and a smart trash can. The above two types of trash cans can automatically open or close the trash can opening before and after the trash is disposed of. Moreover, when the trash in the trash bag reaches a certain amount, it can also automatically pack and replace the bag, which greatly facilitates people's disposal of trash.

[0003] Existing methods for removing garbage bags mainly include opening the bin body and opening the lid. Garbage bins that require opening the lid typically have a double-lid structure, one for disposing of garbage and the other to reveal the packaged garbage bag inside. Existing double-lid garbage bins have the following shortcomings:

[0004] The existing double-cover structure requires manual operation for opening and closing, and cannot be automated, making it inconvenient. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems and provide an intelligent trash can opening structure that can automatically complete the opening and closing of both lids, has a high degree of intelligence, and is more convenient to use.

[0006] Another object of the present invention is to provide a smart trash can.

[0007] The objective of this invention is achieved through the following technical solution:

[0008] A smart trash can opening structure includes a large lid structure and a small lid structure disposed on the large lid structure;

[0009] The large cover structure includes a large cover body and a large cover opening and closing drive mechanism for driving the large cover body to open and close. The large cover body is rotatably connected to the top of the trash can body, and the large cover body is provided with a trash disposal port that communicates with the inner cavity of the trash can.

[0010] The small cover structure includes a small cover body and a small cover opening and closing drive mechanism for driving the small cover body to open and close. The small cover body is rotatably connected to the top of the large cover body. In the closed state, the small cover body covers the waste disposal port.

[0011] Both the large lid opening and closing drive motor and the small lid opening and closing drive mechanism are electrically connected to the controller of the trash can.

[0012] The working principle of the opening mechanism of the above-mentioned smart trash can is as follows:

[0013] When the device is in operation, if you need to dispose of garbage, the controller sends an open signal to the small cover opening and closing drive mechanism. The small cover opening and closing drive mechanism drives the small cover to open, exposing the garbage disposal opening of the large cover. Then, the garbage can be thrown into the garbage bag inside the garbage can. The small cover is then driven to close by the small cover opening and closing drive mechanism.

[0014] When the garbage bag reaches a certain amount, the garbage bag is packed by the garbage bin's collection mechanism and sealing separation mechanism. After packing, the controller sends an open signal to the lid opening and closing drive mechanism, which drives the entire lid to open, revealing the packed garbage bag. The packed garbage bag is then manually removed, and the lid is closed again by the lid opening and closing drive mechanism.

[0015] In a preferred embodiment of the present invention, a fixed frame is provided at the top of the barrel body, and the large cover is rotatably connected to the fixed frame.

[0016] In a preferred embodiment of the present invention, the lid opening and closing drive mechanism includes a lid opening and closing drive motor and a lid opening and closing transmission assembly. The housing of the lid opening and closing drive motor is fixed to the barrel body, and the output shaft of the lid opening and closing drive motor is parallel to the rotation center of the lid body. The lid opening and closing transmission assembly includes a lid crank arm and a swing frame. One end of the lid crank arm is connected to the output shaft of the lid opening and closing drive motor, and the other end of the lid crank arm is hinged to one end of the swing frame. The other end of the swing frame is hinged to the end of the lid body closest to its own rotation center. With the above structure, driven by the lid opening and closing drive motor, the lid crank arm swings upward around the output shaft of the lid opening and closing drive motor, lifting the swing frame, and then transmitting power to the lid body through the swing frame, thereby opening the lid body. Conversely, in the opposite direction, the lid crank arm is driven downward by the lid opening and closing drive motor, thereby closing the lid body.

[0017] Furthermore, the cover opening and closing drive mechanism also includes a cover overload slip structure, which includes a cover overload slip wheel and a cover overload slip tooth groove. The cover overload slip wheel is coaxially fixedly connected to the output shaft of the cover opening and closing drive motor, and the cover overload slip wheel is coaxially arranged in the mounting hole of the cover crank arm.

[0018] The overload slip groove of the cover is provided in multiple places and is arranged along the circumferential direction on the inner wall of the mounting hole of the cover crank arm.

[0019] The outer surface of the overload slip wheel of the large cover is provided with overload slip drive teeth that mate with the overload slip groove of the large cover. There are at least two such drive teeth, evenly distributed along the circumference. These drive teeth are made of a material that can elastically deform and has a certain degree of hardness (e.g., rubber, the hardness of which can be selected according to actual needs). With this structure, under the drive of the large cover opening and closing drive motor, the overload slip wheel can smoothly transmit power to the large cover crank arm, thereby realizing the opening and closing operation. Furthermore, during the use of the trash can, the large cover opening and closing drive motor is generally in a stopped state or driven according to a fixed pace. There may be situations where external force pushes the large cover to flip up and down. The large cover, through the swing frame, drives the large cover crank arm to swing, transmitting the external force towards the large cover opening and closing drive motor. To protect the cover opening and closing drive motor, if the external force is large, under the compression of the cover overload slip groove, the cover overload slip drive teeth on the cover overload slip wheel will undergo elastic deformation to avoid the cover overload slip groove and rotate forward. At this time, slippage occurs until the external force disappears. The cover overload slip drive teeth will recover their deformation and continue to be supported in the cover overload slip groove in order to transmit the power from the cover opening and closing drive motor. The structure is very ingenious.

[0020] Furthermore, the lid opening and closing drive mechanism also includes a lid-storing torsion spring. This torsion spring is sleeved on the columnar mounting part of the lid crank arm or the lid overload slip wheel. Both ends of the torsion spring are fixedly connected to the fixed structure of the barrel body and the lid crank arm, respectively. The columnar mounting part is coaxial with the output shaft of the lid opening and closing drive motor. When the lid is closed, the torsion spring is in a deformation-storing energy state. Through this structure, when the lid flips downwards to close, the driving force of the lid opening and closing drive motor and the weight of the lid itself simultaneously drive the torsion spring to twist, causing it to gradually deform and store energy until the lid is completely closed. When it is necessary to open the lid, the lid opening and closing drive motor drives the lid to flip upwards. At the same time, the torsion spring releases its potential energy and recovers its deformation, thereby providing a certain auxiliary thrust to the lid opening and closing drive motor to ensure that the lid can be opened smoothly. This reduces the driving force required by the motor that drives the lid opening and closing, meaning a lower-power motor can be used to complete the lid opening operation. This helps to reduce the size of the motor, thereby increasing the internal space of the bin and reducing the overall volume of the trash can, resulting in higher space utilization.

[0021] In a preferred embodiment of the present invention, the small cover is connected to the large cover via an intermediate hinge.

[0022] In a preferred embodiment of the present invention, the small cover opening and closing drive mechanism includes a small cover opening and closing drive motor and a small cover opening and closing transmission assembly; the housing of the small cover opening and closing drive motor is fixed to the large cover body, and the output shaft of the small cover opening and closing drive motor is parallel to the rotation center of the small cover body; the small cover opening and closing transmission assembly includes a small cover crank arm and a swing rod, one end of the small cover crank arm is connected to the output shaft of the small cover opening and closing drive motor, and the other end of the small cover crank arm is hinged to one end of the swing rod; the other end of the swing rod is hinged to the small cover body or an intermediate hinge member. With the above structure, driven by the small cover opening and closing drive motor, the small cover crank arm swings upward around the output shaft of the small cover opening and closing drive motor, lifting the swing rod, and then transmitting power to the small cover body through the swing rod, thereby opening the small cover body. Conversely, in the opposite direction, the small cover crank arm is driven downward by the small cover opening and closing drive motor, thereby closing the small cover body.

[0023] Furthermore, the small cover opening and closing drive mechanism also includes a small cover overload slip structure, which includes a small cover overload slip wheel and a small cover overload slip tooth groove. The small cover overload slip wheel is coaxially fixedly connected to the output shaft of the small cover opening and closing drive motor, and the small cover overload slip wheel is coaxially arranged in the mounting hole of the small cover crank arm.

[0024] The small cover has multiple overload slip grooves, which are arranged along the circumferential direction on the inner wall of the mounting hole of the small cover crank arm.

[0025] The outer surface of the small cover overload slip wheel is provided with small cover overload slip drive teeth that mate with the small cover overload slip groove. There are at least two small cover overload slip drive teeth, evenly distributed along the circumference. These small cover overload slip drive teeth are made of a material that can elastically deform and has a certain degree of hardness (e.g., rubber, the hardness of which can be selected according to actual needs). Through this structure, under the drive of the small cover opening and closing drive motor, the small cover overload slip wheel can smoothly transmit power to the small cover crank arm, thereby realizing the opening and closing operation. Furthermore, during the use of the trash can, the small cover opening and closing drive motor is generally in a stopped state or in a state of driving according to a fixed pace. There may be situations where external force pushes the small cover to flip up and down. The small cover body drives the small cover crank arm to swing through the swing rod, transmitting the external force in the direction of the small cover opening and closing drive motor. To protect the cover opening and closing drive motor, if the external force is large, under the pressure of the cover overload slip groove, the cover overload slip drive teeth on the cover overload slip wheel will undergo elastic deformation to avoid the cover overload slip groove and rotate forward. At this time, slippage occurs until the external force disappears. The cover overload slip drive teeth will recover their deformation and continue to be supported in the cover overload slip groove so as to transmit the power from the cover opening and closing drive motor. The structure is very ingenious.

[0026] Furthermore, the small cover opening and closing drive mechanism also includes a small cover energy-storing torsion spring. This small cover energy-storing torsion spring is sleeved on the cylindrical mounting part of the small cover crank arm or the small cover overload slip wheel. Both ends of the small cover energy-storing torsion spring are fixedly connected to the large cover body and the small cover crank arm, respectively. The cylindrical mounting part is coaxial with the output shaft of the small cover opening and closing drive motor. When the small cover is closed, the small cover energy-storing torsion spring is in a deformation-storing energy state. Through this structure, the driving force required by the small cover opening and closing drive motor can be reduced, meaning a lower-power motor can be used to complete the opening operation. This helps to reduce the size of the small cover opening and closing drive motor, thereby increasing the internal space of the bin and reducing the overall volume of the trash can, resulting in higher space utilization.

[0027] In a preferred embodiment of the present invention, the large cover body is provided with a storage box for holding unused garbage bags.

[0028] A smart trash can includes a body and a lid opening structure.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] The opening structure of the present invention realizes the opening and closing operation of the large cover and the small cover through the large cover opening and closing drive mechanism and the small cover opening and closing drive mechanism, respectively. It does not require manual operation, has a high degree of intelligence, and is more convenient to use. Attached Figure Description

[0037] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0038] Referring to Figures 1-2, the smart trash can of this embodiment includes a can body 1 and a lid opening structure. The lid opening structure includes a large lid structure and a small lid structure disposed on the large lid structure. The large lid structure includes a large lid body 2 and a large lid opening and closing drive mechanism for driving the large lid body 2 to open and close. The large lid body 2 is rotatably connected to the top of the trash can body 1, and the large lid body 2 is provided with a trash disposal port 2-1 communicating with the inner cavity of the trash can. The large lid body 2 contains a storage box for storing unused trash bags.

[0039] Furthermore, a fixed frame 3 is provided on the top of the barrel body 1, and the large cover 2 is rotatably connected to the fixed frame 3.

[0040] Referring to Figures 2-4, the lid opening and closing drive mechanism includes a lid opening and closing drive motor 4 and a lid opening and closing transmission assembly. The housing of the lid opening and closing drive motor 4 is fixed to the barrel body 1, and the output shaft of the lid opening and closing drive motor 4 is parallel to the rotation center of the lid body 2. The lid opening and closing transmission assembly includes a lid crank arm 5 and a swing frame 6. One end of the lid crank arm 5 is connected to the output shaft of the lid opening and closing drive motor 4, and the other end of the lid crank arm 5 is hinged to one end of the swing frame 6. The other end of the swing frame 6 is hinged to the end of the lid body 2 closest to its own rotation center. With the above structure, driven by the lid opening and closing drive motor 4, the lid crank arm 5 swings from bottom to top around the output shaft of the lid opening and closing drive motor 4, lifting the swing frame 6, and then transmitting power to the lid body 2 through the swing frame 6, thereby opening the lid body 2. Conversely, in the opposite direction, the cover opening and closing drive motor 4 drives the cover crank arm 5 to swing downward, thereby closing the cover body 2.

[0041] Referring to Figure 3, the cover opening and closing drive mechanism also includes a cover overload slip structure, which includes a cover overload slip wheel 7 and a cover overload slip tooth groove 8. The cover overload slip wheel 7 is coaxially and fixedly connected to the output shaft of the cover opening and closing drive motor 4, and is coaxially disposed in the mounting hole of the cover crank arm 5. The cover overload slip tooth groove 8 is provided in multiple locations and is disposed along the circumferential direction on the inner wall of the mounting hole of the cover crank arm 5. The outer side of the cover overload slip wheel 7 is provided with cover overload slip drive teeth 7-1 that cooperate with the cover overload slip tooth groove 8. There are at least two cover overload slip drive teeth 7-1 and they are evenly distributed along the circumferential direction. The cover overload slip drive teeth 7-1 are made of a material that can be elastically deformed and has a certain hardness (e.g., rubber material, the hardness of which can be selected according to actual needs). With the above structure, driven by the cover opening and closing drive motor 4, the cover overload slip wheel 7 can smoothly transmit power to the cover crank arm 5, thereby realizing the opening and closing operation. Furthermore, during the use of the trash can, the cover opening and closing drive motor 4 is generally in a stopped driving state or in a state of driving according to a fixed pace. There may be a situation where external force pushes the cover body 2 to flip up and down. The cover body 2 drives the cover crank arm 5 to swing through the swing frame 6, transmitting the external force in the direction of the cover opening and closing drive motor 4. To protect the cover opening and closing drive motor 4, if the external force is large, under the compression of the cover overload slip groove 8, the cover overload slip drive tooth 7-1 on the cover overload slip wheel 7 will undergo elastic deformation to avoid the cover overload slip groove 8 and rotate forward. At this time, slippage occurs until the external force disappears. The cover overload slip drive tooth 7-1 returns to its original deformation and continues to be supported in the cover overload slip groove 8 so as to transmit the power from the cover opening and closing drive motor 4. The structure is very ingenious.

[0042] Referring to Figure 3, the lid opening and closing drive mechanism also includes a lid energy-storing torsion spring 9. This torsion spring 9 is sleeved on the columnar mounting part of the lid crank arm 5 or the lid overload slip wheel 7. Both ends of the torsion spring 9 are fixedly connected to the fixing structure of the barrel body 1 and the lid crank arm 5, respectively. The columnar mounting part is coaxial with the output shaft of the lid opening and closing drive motor 4. When the lid body 2 is closed, the lid energy-storing torsion spring 9 is in a deformation-storing energy state. Through this structure, when the lid body 2 flips downwards to close, the driving force of the lid opening and closing drive motor 4 and the gravity of the lid body 2 simultaneously drive the lid energy-storing torsion spring 9 to twist, causing it to gradually deform and store energy until the lid body 2 is completely closed. When the large lid 2 needs to be opened, the large lid opening and closing drive motor 4 drives the large lid 2 to flip upwards. At the same time, the large lid's stored torsion spring 9 releases its potential energy and restores its deformation, thus providing a certain auxiliary thrust to the large lid opening and closing drive motor 4, ensuring that the large lid 2 can be opened smoothly. In this way, the driving force required by the large lid opening and closing drive motor 4 can be reduced, that is, a lower-power motor can be used to complete the lid opening operation. This is beneficial to reducing the size of the large lid opening and closing drive motor 4, thereby increasing the internal space of the bin and reducing the overall volume of the trash can, resulting in higher space utilization.

[0043] Referring to Figures 1 and 4-6, the small cover structure includes a small cover body 10 and a small cover opening and closing drive mechanism for driving the small cover body 10 to open and close. The small cover body 10 is rotatably connected to the top of the large cover body 2. In the closed state, the small cover body 10 covers the garbage disposal opening 2-1. Both the large cover opening and closing drive mechanism and the small cover opening and closing drive mechanism are electrically connected to the garbage bin's controller.

[0044] Referring to Figures 1 and 4-6, the small cover 10 is connected to the large cover 2 via an intermediate hinge 11. The small cover opening and closing drive mechanism includes a small cover opening and closing drive motor 12 and a small cover opening and closing transmission assembly. The housing of the small cover opening and closing drive motor 12 is fixed on the large cover 2, and the output shaft of the small cover opening and closing drive motor 12 is parallel to the rotation center of the small cover 10. The small cover opening and closing transmission assembly includes a small cover crank arm 13 and a swing rod 14. One end of the small cover crank arm 13 is connected to the output shaft of the small cover opening and closing drive motor 12, and the other end of the small cover crank arm 13 is hinged to one end of the swing rod 14. The other end of the swing rod 14 is hinged to the intermediate hinge 11. With the above structure, driven by the small cover opening and closing drive motor 12, the small cover crank arm 13 swings upward around the output shaft of the small cover opening and closing drive motor 12, lifting the swing rod 14, and then transmitting power to the small cover body 10 through the swing rod 14, thereby opening the small cover body 10. Conversely, in the opposite direction, the small cover opening and closing drive motor 12 drives the small cover crank arm 13 to swing downward, thereby closing the small cover body 10.

[0045] Referring to Figure 6, the small cover opening and closing drive mechanism also includes a small cover overload slip structure, which includes a small cover overload slip wheel 15 and a small cover overload slip groove 16. The small cover overload slip wheel 15 is coaxially and fixedly connected to the output shaft of the small cover opening and closing drive motor 12, and is coaxially disposed in the mounting hole of the small cover crank arm 13. The small cover overload slip groove 16 has multiple grooves and is disposed along the circumferential direction on the inner wall of the mounting hole of the small cover crank arm 13. The outer side of the small cover overload slip wheel 15 is provided with small cover overload slip drive teeth 15-1 that cooperate with the small cover overload slip groove 16. There are at least two small cover overload slip drive teeth 15-1 and they are evenly distributed along the circumferential direction. The small cover overload slip drive teeth 15-1 are made of a material that can be elastically deformed and has a certain hardness (e.g., rubber material, the hardness of which can be selected according to actual needs). With the above structure, driven by the small cover opening and closing drive motor 12, the small cover overload slip wheel 15 can smoothly transmit power to the small cover crank arm 13, thereby realizing the opening and closing operation. Furthermore, during the use of the trash can, the small cover opening and closing drive motor 12 is generally in a stopped driving state or in a state of driving according to a fixed pace. There may be a situation where an external force pushes the small cover body 10 to flip up and down. The small cover body 10 drives the small cover crank arm 13 to swing through the swing rod 14, transmitting the external force in the direction of the small cover opening and closing drive motor 12. To protect the cover opening and closing drive motor 12, if the external force is large, under the pressure of the cover overload slip groove 16, the cover overload slip drive tooth 15-1 on the cover overload slip wheel 15 will undergo elastic deformation to avoid the cover overload slip groove 16 and rotate forward. At this time, slippage occurs until the external force disappears. The cover overload slip drive tooth 15-1 recovers its deformation and continues to be supported in the cover overload slip groove 16 so as to transmit the power from the cover opening and closing drive motor 12. The structure is very ingenious.

[0046] Referring to Figure 6, the small cover opening and closing drive mechanism also includes a small cover energy-storing torsion spring 17. This small cover energy-storing torsion spring 17 is sleeved on the columnar mounting part of the small cover crank arm 13 or the small cover overload slip wheel 15. Both ends of the small cover energy-storing torsion spring 17 are fixedly connected to the large cover body 2 and the small cover crank arm 13, respectively. The columnar mounting part is coaxial with the output shaft of the small cover opening and closing drive motor 12. When the small cover body 10 is closed, the small cover energy-storing torsion spring 17 is in a deformation-storing energy state. Through this structure, the driving force required by the small cover opening and closing drive motor 12 can be reduced, meaning a lower-power motor can be used to complete the opening operation. This helps to reduce the size of the small cover opening and closing drive motor 12, thereby expanding the internal space of the bin and reducing the overall volume of the trash can, resulting in higher space utilization.

[0047] Referring to Figure 1-2, the working principle of the opening structure in this embodiment is as follows:

[0048] When the device is in operation, if you need to dispose of garbage, the controller sends an open signal to the small cover opening and closing drive mechanism, which drives the small cover 10 to open, exposing the garbage disposal port 2-1 of the large cover 2. Then, the garbage can be thrown into the garbage bag inside the garbage can. The small cover 10 is then driven to close by the small cover opening and closing drive mechanism.

[0049] When the amount of garbage in the garbage bag reaches a certain level, the garbage bag is packaged by the garbage bin's collection mechanism and sealing separation mechanism. After packaging, the controller sends an open signal to the large cover opening and closing drive mechanism, which drives the entire large cover 2 to open, revealing the packaged garbage bag. The packaged garbage bag is then manually removed, and the large cover 2 is then driven to close by the large cover opening and closing drive mechanism.

[0050] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
