Description

Technical Field

[0001] This utility model relates to the field of trash can technology, specifically to a trash can. Background Technology

[0002] Trash cans are essential household items used to hold garbage. They come in various forms, and existing trash cans offer multiple opening methods, such as foot-operated, push-button, and sensor-activated opening. For example, Chinese utility model patent CN208531344U discloses a lift-up lid trash can. In this patent, the lid has a vertical sliding rod, and the body has a vertical guide groove. The lid slides vertically through the cooperation of the sliding rod and guide groove. To ensure sufficient space for garbage disposal after opening, the sliding rod and guide groove need to be long enough, requiring deep holes in the can. This increases the can's wall thickness and occupies more space. Furthermore, when the sliding rod moves up and down, friction is generated between it and the inner wall of the guide groove. Overcoming this friction requires greater force, making the operation inconvenient and resulting in a poor user experience. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] This utility model mainly addresses the shortcomings of the existing technology, specifically relating to a trash can. It solves the problems in the existing technology where, when the lid and body of the trash can slide open vertically through the cooperation of a sliding rod and a guide groove, on the one hand, the thickness of the trash can wall is increased, requiring a large space in the trash can, and on the other hand, the user needs to exert more force to drive the sliding rod to move, resulting in inconvenience for the user and a poor user experience.

[0005] (II) Technical Solution

[0006] This utility model relates to a trash can, including a can body, a lid, and a connecting structure. The can body includes an opening for disposing of trash, and the lid is disposed at the opening. One end of the connecting structure is movably connected to the can body, and the other end is movably connected to the lid. A vertical line passing through the center point of the connecting structure is defined as a reference line. When the lid is driven away from the can body, it causes the end of the connecting structure to move toward the reference line or to extend, so that the connecting structure supports the lid and opens the opening. When the lid is driven toward the can body, it causes the end of the connecting structure to move away from the reference line or to compress, so that the opening is closed.

[0007] The advantages are that when the lid moves relative to the bin, the end of the connecting structure moves closer to the reference line or extends, causing the connecting structure to tend towards a vertical state. This supports the lid opening, facilitating waste disposal. When the end of the connecting structure moves away from the reference line or compresses, the connecting structure tends towards a horizontal state, allowing the lid to close and prevent odors from escaping. When the lid moves closer to or away from the bin, the end of the connecting structure moves closer to or away from the vertically extending reference line, causing the end of the connecting structure to move in a roughly lateral direction. This reduces the contact area between the connecting structure and the bin or lid, thus reducing friction and the user's driving force. This makes operation more convenient and improves the user experience. At the same time, it reduces the area available for the connecting structure to move in the vertical direction, meaning it doesn't need to occupy a large space in the bin.

[0008] In one alternative implementation, the direction of movement of the cover is parallel to the reference line.

[0009] The advantage is that, since the reference line extends vertically, when the direction of the lid's movement is parallel to the reference line, the lid will also move vertically to open or close the bin opening, making it convenient to dispose of garbage and conforming to the user's operating habits. At the same time, when the user opens the lid, it can also reduce the direct impact of pungent odors from inside the bin on the user, resulting in a better user experience.

[0010] In one optional embodiment, the connecting structure includes a first connecting rod having a first end and a second end disposed opposite to each other. The first end is slidably connected to the cover, and the second end is movably connected to the bucket. It is adapted that, as the cover moves away from the bucket, the first end moves closer to the reference line; and as the cover moves closer to the bucket, the first end moves away from the reference line.

[0011] The advantage is that the connection between the bucket body and the lid is simple and easy to assemble. When the first end moves closer to the reference line, the first connecting rod gradually tends to the vertical direction, which makes it easier for the first connecting rod to support the lid to open the bucket and dispose of garbage. When the first end moves away from the reference line, the first connecting rod gradually tends to the horizontal direction, which drives the lid connected to it to move towards the bucket body and close the bucket opening.

[0012] In one optional embodiment, a first sliding portion is provided at the first end, and a first sliding engagement portion that cooperates with the first sliding portion is provided on the cover.

[0013] The advantage is that when the first end moves with the cover through the cooperation of the first sliding part and the first sliding mating part, it is easy to assemble and position.

[0014] In one alternative embodiment, the first sliding part is a slider, and the first sliding engagement part is a groove.

[0015] The advantage is that when the first sliding part and the first sliding mating part are set as a sliding block and a sliding groove mating method, the structure is simple and easy to process and assemble.

[0016] In one optional embodiment, the surface where the first sliding part abuts against the first sliding mating part is an arc surface.

[0017] The advantage is that when the first end moves closer to or further away from the reference line, it will have a certain displacement in the horizontal direction relative to the cover. The arc surface allows the first end to move smoothly relative to the cover when it moves, and it can also reset more smoothly, avoiding jamming and providing a better user experience.

[0018] In one optional embodiment, the first sliding part is provided with a limiting part, and the first sliding mating part is provided with a limiting mating part. When the first sliding part and the first sliding mating part are engaged, the limiting part and the limiting mating part are engaged and connected.

[0019] The advantage is that by setting a limiting part and a limiting mating part, the first sliding part and the first sliding mating part can be prevented from disengaging during the sliding process of the first connecting rod.

[0020] In one optional embodiment, the limiting part is a protruding structure, and the limiting mating part is a groove-shaped structure.

[0021] The advantages are that the limiting and matching method of the protrusion and groove structure is simple, easy to produce and assemble, and has better stability.

[0022] In one alternative embodiment, the second end is slidably connected to the barrel body, and is adapted such that, as the lid moves away from the barrel body, the first end and the second end move closer to the reference line; and as the lid moves closer to the barrel body, the first end and the second end move away from the reference line.

[0023] The advantage is that when the second end is also set to slide to the barrel, the first and second ends can slide closer to or further away from the reference line as the lid moves relative to the barrel. This gives the first connecting rod more freedom of movement, reduces jamming during the lid's driving process, and also reduces the difficulty of resetting the lid.

[0024] In one alternative implementation, the second end has the same structure as the first end.

[0025] The advantage is that by designing the first and second ends of the first connecting rod to have the same structure, on the one hand, the synchronous movement of the two ends of the first connecting rod is better, and on the other hand, it is easier to produce and reduces the difficulty of assembly.

[0026] In one optional embodiment, the connecting structure includes a second connecting rod that is shaped to the first connecting rod, and the first connecting rod and the second connecting rod are located on the same side of the barrel.

[0027] The advantage is that the first and second connecting rods are designed to mimic the shape of each other, allowing them to be manufactured using a single mold and then assembled to form a connecting structure, thus reducing costs. By placing the first and second connecting rods on the same side of the bucket, the bucket and the lid each have at least two connection points with the connecting structure, making the lid move more smoothly relative to the bucket and preventing it from tilting during movement.

[0028] In one alternative embodiment, the first connecting rod and the second connecting rod are arranged in an "X", "V" or "Λ" shape.

[0029] The advantage is that a reference line is formed at the midpoint between the first connecting rod and the second connecting rod. The first connecting rod and the second connecting rod are symmetrically arranged along the reference line. On the one hand, it is convenient for the first connecting rod and the second connecting rod to move towards each other and get closer to the reference line, or to move away from each other and get further away from the reference line. On the other hand, a stable triangle is formed between the first connecting rod and the second connecting rod, so that when the cover moves away from the barrel, the cover can stay in that position for a certain period of time.

[0030] In one optional embodiment, at least two connecting structures are provided, and are respectively located on opposite sides of the barrel body and the cover body.

[0031] The advantage is that when multiple connecting structures are respectively located on opposite sides of the barrel and the lid, the lid can remain stable and prevent it from tilting.

[0032] In one alternative implementation, the multiple connection structures move synchronously.

[0033] The advantage is that synchronized movement further prevents the cover from tilting.

[0034] In one alternative embodiment, the lid is provided with a drive unit on the side opposite to the barrel body to drive the lid to move.

[0035] The advantage is that the lid is usually designed to be larger in size to cover the mouth of the bucket, making it inconvenient to operate the lid directly by hand. The lid is moved by a drive unit, making it easier for the user to operate the lid.

[0036] In one alternative embodiment, the lid is driven by gravity to move toward the direction of the barrel.

[0037] The advantage is that after users lift the lid to dispose of garbage, the lid will automatically return to its original position by gravity when the user releases the lid. Users do not need to press the lid to return to its original position, which is convenient for users. Even if the user forgets to close the lid, it will automatically close by gravity to prevent odors from escaping. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] Example 1:

[0051] according to Figure 1-5 As shown, this utility model relates to a trash can, including a can body 30, a lid 20, and a connecting structure 10. The can body 30 includes a can opening 31 for disposing of trash. The lid 20 is disposed at the can opening 31. One end of the connecting structure 10 is movably connected to the can body 30, and the other end is movably connected to the lid 20. A vertical line passing through the center point of the connecting structure 10 is defined as a reference line 40. When the lid 20 is driven away from the can body 30, it causes the end of the connecting structure 10 to move towards the reference line 40, so that the connecting structure 10 supports the lid 20 and opens the can opening 31. When the lid 20 is driven towards the can body 30, it causes the end of the connecting structure 10 to move away from the reference line 40, so that the can opening 31 is closed.

[0052] Specifically, when the lid 20 moves relative to the bin 30, the end of the connecting structure 10 moves closer to the reference line 40, causing the connecting structure 10 to tend towards a vertical state, thereby supporting the lid to open the bin opening 31 for easy garbage disposal. When the end of the connecting structure 10 moves away from the reference line 40, the connecting structure 10 tends towards a horizontal state, so that the lid 20 can close the bin opening 31 to prevent odors from escaping. When the lid 20 moves away from or closer to the bin 30, the end of the connecting structure 10 moves closer to or further away from the vertically extending reference line 40, causing the end of the connecting structure 10 to move in a roughly lateral direction. This reduces the contact area between the connecting structure 10 and the bin 30 or the lid 20, thereby reducing friction and reducing the user's driving force, making operation more convenient and improving the user experience. At the same time, it reduces the area of ​​the bin 30 for the connecting structure 10 to move in the vertical direction, meaning it does not need to occupy a large space in the bin 30.

[0053] The bin body 30 is used to form a garbage-receiving chamber. The bin body 30 has a bin opening 31 for garbage to enter the bin body 30 through the bin opening 31. Preferably, the bin opening 31 is located at the top of the bin body 30 so that users can throw garbage from top to bottom, which conforms to user operating habits. The cover 20 is a cover plate that covers the bin opening 31. Therefore, the cover 20 is located at the bin opening 31. The cover 20 can prevent the odor inside the bin body 30 from escaping. In order to facilitate garbage disposal, the cover 20 and the bin body 30 are movable. That is, when the cover 20 is away from the bin opening 31, the bin opening 31 is opened to allow users to throw garbage. When the cover 20 is close to the bin opening 31, the bin opening 31 is closed to prevent the odor from escaping.

[0054] The connecting structure 10 connects the barrel body 30 and the lid 20. Therefore, one end of the connecting structure 10 is movably connected to the lid 20, and the other end is movably connected to the barrel body 30. In this example, the preferred movable connection is a sliding or rotating connection. That is, one end of the connecting structure 10 is slidably connected to the barrel body 30, and the other end is also slidably connected to the lid 20. It can also be rotatably connected to the lid 20. It can be understood that one end of the connecting structure 10 is slidably connected to the lid 20, and the other end is also slidably or rotatably connected to the barrel 30. It can also be understood that one end of the connecting structure 10 is rotatably connected to the lid 20, and the other end is also rotatably connected to the barrel 30.

[0055] Reference line 40 is a vertical line passing through the center point of the connecting structure 10. In this example, when the connecting structure 10 is connected to one end of the barrel 30 and the lid 20 respectively, the midpoint of the line connecting the two ends is the center point of the connecting structure 10. When the connecting structure 10 is connected to multiple ends of the barrel 30 and the lid 20 respectively, the center point of the connecting structure 10 is the midpoint of the line connecting one pair of motion-related ends. When the shape of the connecting structure 10 is non-standard, its center point is its center of gravity.

[0056] When the lid 20 moves away from the bin 30, the lid 20 will open the bin opening 31 to facilitate the user's disposal of garbage. The end of the connecting structure 10 will move toward the reference line 40. Specifically, when the length of the connecting structure 10 is constant, the end of the connecting structure 10 connected to the bin 30 moves toward the reference line 40, and when the end of the connecting structure 10 connected to the lid 20 rotates around its central axis, it will drive the connecting structure 10 to move to a more vertical state, thereby supporting the lid 20 and keeping the lid 20 in the open bin opening 31 state.

[0057] Understandably, when the end of the connecting structure 10 connected to the lid 20 moves close to the reference line 40, and when the end of the connecting structure 10 connected to the barrel 30 rotates around its central axis, it will cause the connecting structure 10 to move to a more vertical state, thereby supporting the lid 20 and keeping the lid 20 in the open barrel 31 state.

[0058] Understandably, when the end of the connecting structure 10 connected to the lid 20 moves closer to the reference line 40, and the end of the connecting structure 10 connected to the barrel 30 moves closer to the reference line 40, it will drive the connecting structure 10 to move to a more vertical state, thereby supporting the lid 20 and keeping the lid 20 in the open barrel 31 state.

[0059] When the lid 20 moves closer to the bin 30, the lid 20 will close the bin opening 31 to prevent the user from throwing away garbage and to prevent odors from escaping. The end of the connecting structure 10 will move away from the reference line 40. Specifically, when the length of the connecting structure 10 is constant, the end of the connecting structure 10 connected to the bin 30 moves away from the reference line 40, and the end of the connecting structure 10 connected to the lid 20 rotates around its central axis, which will drive the connecting structure 10 to move to a more vertical state, thereby causing the lid 20 to cover the bin opening 31 and close the bin opening 31.

[0060] Understandably, when the end of the connecting structure 10 connected to the lid 20 moves away from the reference line 40 and the end of the connecting structure 10 connected to the barrel 30 rotates around its central axis, it will cause the connecting structure 10 to move to a more vertical state, thereby causing the lid 20 to cover the barrel opening 31 and close the barrel opening 31.

[0061] Understandably, when the end of the connecting structure 10 connected to the cover 20 moves away from the reference line 40, and the end of the connecting structure 10 connected to the barrel 30 moves away from the reference line 40, it will cause the connecting structure 10 to move to a state that tends to be vertical, thereby causing the cover 20 to block the barrel opening 31 and close the barrel opening 31.

[0062] In one optional embodiment, the moving direction of the cover 20 is parallel to the reference line 40. Since the reference line 40 extends vertically, when the moving direction of the cover 20 is parallel to the reference line 40, the cover 20 will also move vertically to open or close the bin opening 31, which facilitates garbage disposal and conforms to the user's operating habits. At the same time, when the user opens the cover 20, it can also reduce the direct impact of irritating odors from inside the bin 30 on the user, resulting in a better user experience.

[0063] In one optional embodiment, the connecting structure 10 includes a first connecting rod 11, which has a first end 111 and a second end 112 disposed opposite to each other. The first end 111 is slidably connected to the cover 20, and the second end 112 is movably connected to the bucket 30. This allows the first end 111 to move closer to the reference line 40 as the cover 20 moves away from the bucket 30. As the cover 20 moves closer to the bucket 30, the first end 111 moves away from the reference line 40. The first connecting rod 11 connects the bucket 30 and the cover 20, making the connection simple and easy to assemble. When the first end 111 moves closer to the reference line 40, the first connecting rod 11 gradually tends towards the vertical direction, facilitating the first connecting rod 11 to support the cover 20 to open the bucket opening 31 for garbage disposal. When the first end 111 moves away from the reference line 40, the first connecting rod 11 gradually tends towards the horizontal direction, causing the cover 20 connected to it to move towards the bucket 30 to close the bucket opening 31.

[0064] The first connecting rod 11 is a horizontal rod structure. In this example, the first end 111 and the second end 112 are preferably the two opposite ends of the first connecting rod 11. The first end 111 is slidably connected to the cover 20, meaning that the first end 111 can slide a certain displacement in the horizontal direction relative to the cover 20. This sliding can be achieved by a slider and groove, magnetic attraction, or gear and rack. The second end 112 is movably connected to the barrel 30. In this example, the second end 112 is preferably slidably connected to the barrel 30. The connection method can be... The first end 111 and the cover 20 are connected in the same way, or in other sliding ways. Understandably, the second end 112 can be connected to the barrel 30 by rotation. For example, the second end 112 can be connected to the barrel 30 by a rotating shaft and shaft hole. This allows the first connecting rod 11 to rotate around the first end 111 in the first direction to a vertical state when the cover 20 moves away from the barrel 30, and the first connecting rod 11 to rotate around the first end 111 in the opposite direction to the first direction to a horizontal state when the cover 20 moves closer to the barrel 30.

[0065] Understandably, when the two ends of the first connecting rod 11 slide and the cover 20 moves away from the barrel 30, the first connecting rod 11 rotates around its midpoint in the first direction to a more vertical state, while when the cover 20 moves closer to the barrel 30, the first connecting rod 11 rotates around its midpoint in the opposite direction to the first direction to a more horizontal state.

[0066] In one optional embodiment, a first sliding part 12 is provided at the first end 111, and a first sliding engagement part 21 is provided on the cover 20 to cooperate with the first sliding part 12. When the first end 111 and the barrel 30 move through the cooperation of the first sliding part 12 and the first sliding engagement part 21, it is convenient for assembly and positioning.

[0067] The first sliding part 12 can be integrally formed at the first end 111, or it can be separately formed and then installed at the first end 111. Similarly, the first sliding mating part 21 can be integrally formed on the cover 20, or it can be separately installed on the cover 20. In this example, the preferred first sliding part 12 and the first sliding mating part 21 are a slider and a groove, that is, the first sliding part 12 is a slider and the first sliding mating part 21 is a groove. The first sliding part 12 is inserted into the first sliding mating part 21 for relative sliding. Of course, the two can also be interchanged. The slider and groove mating method has a simple structure and is easy to process and assemble.

[0068] Understandably, the first sliding part 12 is a magnet, and the first sliding mating part 21 is a magnet or iron sheet with opposite magnetism. The first sliding part 12 and the first sliding mating part 21 can be connected by magnetic attraction, and can also slide relative to each other in the horizontal direction.

[0069] Understandably, the first sliding part 12 is a gear, and the first sliding engagement part 21 is a rack. The first sliding part 12 and the first sliding engagement part 21 are connected by the meshing of the gear and the rack. The sliding connection between the first sliding part 12 and the first sliding engagement part 21 is achieved by the rotation of the gear and the relative movement of the rack.

[0070] In one optional embodiment, the surface where the first sliding part 12 abuts against the first sliding mating part 21 is an arc surface. When the first end 111 moves closer to or further away from the reference line 40, it will generate a certain displacement with the cover 20 in the horizontal direction. The arc surface allows the first end 111 to move smoothly relative to the cover 20 when it moves, and it can also reset more smoothly, avoiding jamming and improving the user experience. As the first sliding part 12 and the first sliding mating part 21 slide relative to each other, the first sliding part 12 will gradually rotate at the first end 111 to tend to be vertical or horizontal. When the end of the first sliding part 12 is set with an arc surface, the first sliding part 12 does not have a sense of jerking when it rotates and slides, resulting in a better user experience.

[0071] In one optional embodiment, the first sliding part 12 is provided with a limiting part 14, and the first sliding engagement part 21 is provided with a limiting engagement part 23. When the first sliding part 12 engages with the first sliding engagement part 21, the limiting part 14 and the limiting engagement part 23 are engaged and connected. The limiting part 14 and the limiting engagement part 23 are provided to prevent the first sliding part 12 from disengaging from the first sliding engagement part 21 during the sliding process of the first connecting rod 11.

[0072] In one optional embodiment, the limiting part 14 is a protruding structure, and the limiting mating part 23 is a groove-shaped structure. In this example, the side of the first sliding part 12 is preferably provided with a protruding structure, that is, the first sliding part 12 extends to form a protruding structure on the surface opposite to the side wall of the cover 20. Of course, the protruding structure can also be assembled on the first sliding part 12. Correspondingly, a groove-shaped limiting mating part 23 is also provided on the side wall of the first sliding mating part, that is, a groove-shaped channel is opened on the side wall of the cover 20 to facilitate the sliding of the limiting block therein. The limiting mating method of the protruding and groove-shaped structures is simple in structure, easy to manufacture and assemble, and has better stability.

[0073] Understandably, the first sliding part 12 extends to form a protruding structure on the top surface opposite to the cover 20, and the bottom of the corresponding first sliding mating part 21 is provided with a groove-shaped limiting mating part 23.

[0074] Understandably, the limiting part 14 and the limiting mating part 23 can also be configured to be magnetically fixed.

[0075] In one optional embodiment, the second end 112 is slidably connected to the barrel 30, which is suitable for the first end 111 and the second end 112 to move closer to the reference line 40 during the process of the lid 20 moving away from the barrel 30; during the process of the lid 20 moving closer to the barrel 30, the first end 111 and the second end 112 move away from the reference line 40. When the second end 112 is also slidably connected to the barrel 30, the first end 111 and the second end 112 can both move closer to or away from the reference line 40 by sliding during the process of the lid 20 moving relative to the barrel 30. This gives the first connecting rod 11 a better degree of freedom during movement, reduces jamming during the driving process of the lid 20, and also reduces the difficulty of resetting the lid 20.

[0076] In one optional embodiment, the second end 112 has the same structure as the first end 111. When the structures of the first end 111 and the second end 112 of the first connecting rod 11 are designed to be the same, on the one hand, the synchronous movement effect of the two ends of the first connecting rod 11 is better, and on the other hand, it is easier to produce and reduces the assembly difficulty. In this example, the second end 112 is also provided with a second sliding part 13 with the same structure as the first sliding part 12 on the first end 111. The corresponding part of the barrel 30 that cooperates with the second end 112 is also provided with a second sliding part 32 with the same structure as the first sliding part 21 on the cover 20. At the same time, the second sliding part 13 is also provided with a limiting part 14 with the same structure as the limiting part 14 on the first sliding part 12. The corresponding part of the barrel 30 is also provided with a limiting part 23 with the same structure as the limiting part 23 in the first sliding part 21 at the second sliding part 32.

[0077] In one optional embodiment, the connecting structure 10 includes a second connecting rod 15 that is shaped to the first connecting rod 11. The first connecting rod 11 and the second connecting rod 15 are located on the same side of the barrel 30. The first connecting rod 11 and the second connecting rod 15 are shaped to each other, so that they can be manufactured using a single mold and then assembled to form the connecting structure 10, thereby reducing costs. By placing the first connecting rod 11 and the second connecting rod 15 on the same side of the barrel 30, the barrel 30 and the lid 20 each have at least two connection points with the connecting structure 10, making the lid 20 move more smoothly relative to the barrel 30.

[0078] In one optional embodiment, the first connecting rod 11 and the second connecting rod 15 are arranged in an "X", "V" or "Λ" shape, so that a reference line 40 is formed at the midpoint between the first connecting rod 11 and the second connecting rod 15. The first connecting rod 11 and the second connecting rod 15 are symmetrically arranged along the reference line 40. On the one hand, this facilitates the first connecting rod 11 and the second connecting rod 15 to move towards each other and closer to the reference line 40, or to move away from each other and further away from the reference line 40. On the other hand, a stable triangle is formed between the first connecting rod 11 and the second connecting rod 15. When the cover 20 moves away from the bin 30, the cover 20 can remain in that position for a certain period of time, which is convenient for the user to dispose of garbage. In this example, a pivot is preferably provided at the intersection of the first connecting rod 11 and the second connecting rod 15.

[0079] Understandably, the first connecting rod 11 and the second connecting rod 15 can be arranged in parallel so that they can move synchronously and in the same direction when the cover 20 moves relative to the barrel 30.

[0080] In one optional embodiment, at least two connecting structures 10 are provided, and are respectively provided on opposite sides of the barrel 30 and the lid 20. When multiple connecting structures 10 are respectively provided on opposite sides of the barrel 30 and the lid 20, the lid 20 can maintain a stable state and avoid the lid 20 from tilting to one side when moving relative to the barrel 30. In this example, the multiple connecting structures 10 preferably move synchronously, and synchronous movement can further prevent the lid 20 from tilting.

[0081] In one optional embodiment, the lid 20 is provided with a driving part 22 on the side opposite to the bucket body 30 to drive the lid 20 to move. Usually, the lid 20 is designed to be larger in size in order to cover the bucket opening 31, which makes it inconvenient to operate the lid 20 directly by hand. The driving part 22 drives the lid 20 to move, making it easier for the user to operate the lid 20. The driving part 22 can be a handle, grip, or other structure for the user to manually grasp. In this example, the driving part 22 is preferably located at the center of the lid 20, so that the lid 20 can be pulled up or lowered horizontally.

[0082] In one optional implementation, the lid 20 is driven by gravity to move toward the bin 30. After the user pulls up the lid 20 to dispose of the garbage, when the user releases the lid 20, the lid 20 will automatically reset by gravity. The user does not need to press the lid 20 to reset it, which is convenient for the user. Even if the user forgets to close the lid, it will automatically close by gravity to prevent odors from escaping.

[0083] Example 2:

[0084] This utility model relates to a trash can, including a can body 30, a lid 20, and a connecting structure 10. The can body 30 includes a can opening 31 for disposing of trash. The lid 20 is disposed at the can opening 31. One end of the connecting structure 10 is movably connected to the can body 30, and the other end is movably connected to the lid 20. When the lid 20 is driven away from the can body 30, it causes the connecting structure 10 to extend, so that the connecting structure 10 supports the lid 20 and opens the can opening 31. When the lid 20 is driven closer to the can body 30, it causes the connecting structure 10 to compress, so as to close the can opening 31.

[0085] When the connecting structure 10 is driven to extend, it tends to extend in the vertical direction, thereby supporting the lid to open the bucket opening 31 for easy garbage disposal. When the connecting structure 10 is driven to compress, it tends to extend in the horizontal direction, so that the lid 20 can close the bucket opening 31 to prevent odors from escaping.

[0086] In this example, the connecting structure 10 includes a first connecting rod 11. The two ends of the first connecting rod are rotatably connected to the bucket body 30 and the cover body 20, respectively. The middle part of the first connecting rod 11 can be bent, that is, the first connecting rod 11 is composed of two parts that can rotate relative to each other. When the connecting structure 10 is driven to extend, the two parts rotate to maintain a roughly vertical state or the angle between them increases. To enhance the efficiency of garbage disposal, the angle is preferably greater than 120°, so that the first connecting rod 11 can form a state that tends to be vertical. When the connecting structure 10 is driven to compress, the two parts rotate to maintain a roughly overlapping state or the angle between them decreases, so that the first connecting rod 11 can form a state that tends to be horizontal.

[0087] To ensure the smooth movement of the lid 20 relative to the barrel 30, multiple first connecting rods 11 can be provided in a similar shape and evenly distributed between the lid 20 and the barrel 30. In this example, preferably, the first connecting rod 11 and the second connecting rod 15 are provided on the same side of the barrel 30 and the lid 20, and the first connecting rod 11 and the second connecting rod 15 extend and compress in opposite directions.

[0088] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
