Description

Technical Field

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

[0002] As one of the most common household items, trash cans usually require the combination of trash bags and the can body. When using them, users first unfold the trash bag and lay it inside the trash can, then turn the opening of the trash bag outward and fix it to the opening of the trash can. The trash can provides support for the trash bag, and the opening of the trash bag is left open to facilitate the user's disposal of trash.

[0003] An existing technology includes a pressure trash can comprising a can body and a cover fitted onto it. As the cover gradually closes onto the opening of the can body and moves towards the bottom of the can body, air inside the cover is forced into the trash bag, causing the trash bag to inflate and adhere tightly to the inner wall of the can body. To ensure the trash bag adheres to the wall, the can body is usually provided with vent holes for releasing air between the trash bag and the can body.

[0004] However, existing air-pressure trash cans typically have a drawstring attachment extending from the side wall of the can away from the can body. When the can cover is fitted onto the can body, this attachment is located between the can cover and the can body. To facilitate the installation of the can cover and the can body, a gap sufficient to accommodate the attachment needs to be left between the can cover and the can body. This results in a relatively wide gap between the can cover and the can body. As the can cover moves towards the bottom of the can body, some of the air inside the can cover will be expelled out of the can body along the relatively wide gap between the can cover and the can body. This means that the remaining air pressed into the trash bag by the can cover is insufficient to keep the trash bag tightly against the inner wall of the can body. In other words, the efficiency of the trash bag's expansion and unfolding is poor, thus affecting the user experience. Utility Model Content

[0005] This utility model mainly addresses the shortcomings of the existing technology, specifically relating to a trash can that solves the problem of poor efficiency in expanding and unfolding trash bags in the existing technology.

[0006] To solve the above-mentioned technical problems, this utility model relates to a trash can, including a can body with a can opening, a vent hole and a can cover, which, when closed on the can opening and gradually moved towards the bottom of the can body, causes a trash bag with a drawstring inside the can to expand and unfold. The vent hole is used to expel air between the trash bag and the can body. A through-hole is provided on the side wall of the can body. When the trash bag is laid inside the can body, the free end of the drawstring passes through the through-hole from inside the can body to the outside of the can body, so as to be driven to move away from the can body to close the opening of the trash bag.

[0007] The advantages are that the protruding part is used to position the drawstring. The protruding part is located on the side wall of the bin, and the free end of the drawstring can pass through the protruding part from the inside of the bin to the outside. This means that the structure for positioning the drawstring does not need to extend from the side wall of the bin away from the bin. As the bin cover moves relative to the bin, the gap between the bin cover and the bin can be set small enough that the bin cover can even be fitted tightly against the side wall of the bin. When the bin cover moves towards the bottom of the bin, less air is lost through the gap between the bin cover and the bin. This means that most of the air inside the bin cover is used on the garbage bag, allowing the garbage bag to adhere better to the inner wall of the bin, resulting in a better user experience.

[0008] In one optional embodiment, the protruding part is a through hole penetrating the side wall, and the free end of the drawstring protrudes from the inside of the barrel to the outside of the barrel through the through hole.

[0009] The advantage is that when the outlet is set as a through hole, the outlet does not need to be set with an extension structure positioning drawstring on the side wall of the bin. This allows the bin cover to move close to or even tightly against the side wall of the bin and toward the bottom of the bin, thereby making the gap between the bin cover and the bin body small enough to further reduce the amount of air loss inside the bin cover and improve the laying effect of the garbage bag.

[0010] In one optional embodiment, the protruding part is a strip-shaped groove with an open top formed by the downward indentation of the top of the side wall. After the free end of the drawstring is driven to move so that the opening of the garbage bag is closed, the drawstring moves out of the strip-shaped groove from the opening, so that the garbage bag can be removed from the bin.

[0011] The advantage is that the groove makes it easier for users to pull the free end of the drawstring and the end near the bag body. This allows the drawstring to be inserted into the groove from top to bottom to position it, making it more convenient for users to operate. It also makes it easier to pull the drawstring and remove the garbage bag after it has been sealed.

[0012] In one alternative embodiment, a mounting plate is provided at the top of the sidewall extending away from the barrel body, and the protruding portion is provided on the mounting plate.

[0013] The advantage is that when the mounting plate is placed at the top of the side wall, it will not occupy the space of the side wall of the bin. This allows the cover to be close to or even flush against the side wall of the bin and move towards the bottom of the bin. This results in a small enough gap between the cover and the bin, further reducing the amount of air loss inside the cover, and improving the laying effect of the garbage bag. At the same time, it will not damage the overall structure of the bin, making the bin more aesthetically pleasing.

[0014] In one alternative embodiment, the top of the sidewall is recessed downward to form a mounting groove, and the bottom of the mounting groove extends away from the barrel body to form a mounting plate.

[0015] The advantage is that when the mounting plate is installed in the mounting groove at the top of the side wall, the mounting plate will not protrude completely from the top of the side wall, thereby reducing the gap between the top of the barrel cover and the top of the side wall, making the barrel cover and barrel body fit together more tightly.

[0016] In one optional embodiment, the mounting plate includes a base plate and an extension plate, one side of the base plate is fixedly connected to the bottom of the mounting groove, and the other side is fixedly connected to the extension plate, with the protruding portion disposed on the extension plate.

[0017] The advantage is that the mounting plate is divided into two parts. The base plate is used to connect the extension plate and the barrel. Since the extension plate with the protruding part needs to withstand a certain amount of tension when the rope is pulled, the base plate can make the extension plate more securely connected to the barrel.

[0018] In one alternative embodiment, the thickness of the base plate and the extension plate is greater than the wall thickness of the barrel body.

[0019] The advantage is that, since the protrusion is located on the extension plate, when the drawstring is pulled, at least the extension plate will be subjected to a certain amount of tension. Therefore, when the wall thickness of the base plate and the extension plate is set to be thicker than that of the barrel, the base plate and the extension plate will be stronger and more stable, and less prone to shaking.

[0020] In one alternative embodiment, the base plate, the extension plate, and the barrel body are integrally formed.

[0021] The advantages are that it facilitates production and assembly, and the one-piece molding improves the strength of the base plate and extension plate. When the draw rope is pulled, the base plate and extension plate are more stable and less prone to shaking.

[0022] In one alternative embodiment, the mounting plate is separately formed and assembled from the barrel body.

[0023] The advantage is that, because the mounting plate is frequently subjected to the tension of the pull rope during use, the connection between the mounting plate and the barrel is prone to fatigue and damage after long-term use. When the mounting plate and the barrel are molded separately and then assembled, it is easier to replace the mounting plate.

[0024] In one optional embodiment, there is a gap between the sidewall of the mounting groove and the mounting plate. The gap is used so that when the bag opening of the garbage bag is fitted onto the outside of the bin, the portion of the bag opening adjacent to the drawstring enters the bin through the gap, so that the free end of the drawstring can pass through the protruding part from the inside of the bin to the outside of the bin.

[0025] The advantage is that when a gap is set between the side wall of the mounting slot and the mounting plate, it is convenient for the garbage bag to be folded over and installed on the top of the bin. Part of the bag opening can enter the bin through the gap, making it easier to pass the drawstring through the outside of the bin.

[0026] In one alternative embodiment, the gaps between the two opposite sidewalls of the mounting groove and the mounting plate are both present.

[0027] The advantage is that it allows for gaps on both sides of the mounting plate. When the garbage bag is folded over and installed on the top of the bin, the two positions of the bag opening adjacent to the drawstring pass through the gaps and enter the bin, so that the mounting plate is located outside the bag opening, making it easy for the drawstring to pass through the protrusion part on the mounting plate.

[0028] In one optional embodiment, the bin body further includes a movable part disposed on the side of the bin opening. When the garbage bag is fitted onto the bin opening, the garbage bag is at least partially disposed on the movable part. When the free end of the drawstring is driven to move away from the bin body, the movable part moves or deforms, causing the opening of the garbage bag to detach from the movable part and be closed.

[0029] The advantage is that the movable part allows the drawstring to move or deform when pulled, so that the bag opening on the movable part can detach from it, and the detached bag opening can be driven to move towards the exit part for closing.

[0030] In one alternative embodiment, the movable part is disposed opposite to the protruding part.

[0031] The advantage is that the pocket openings on the active part can be closed towards the exiting part after being detached, resulting in a better user experience.

[0032] In one alternative embodiment, the movable part is a flexible wall. When the drawstring is pulled, the garbage bag disposed on the movable part drives the movable part to deform, so that the opening of the garbage bag gradually detaches from the movable part and is closed.

[0033] The advantage is that by setting up a flexible wall, when the drawstring is pulled, the flexible wall can be deformed so that the opening of the garbage bag set on the flexible wall can be detached. The flexible wall has good elasticity and toughness, and it can quickly and automatically return to its original shape after being deformed, thus facilitating the next bagging and drawstring closing operation.

[0034] In one optional embodiment, the movable part is a side plate rotatably connected to the side wall of the bin. When the drawstring is pulled, the garbage bag provided on the movable part drives the movable part to rotate toward the protruding part, so that the opening of the garbage bag gradually detaches from the movable part and is closed.

[0035] The advantage is that the side panel allows the drawstring to rotate when pulled, facilitating the detachment of the garbage bag attached to the side panel. The side panel is rotatably connected to the side wall of the bin, allowing it to rotate to an inclined position. This makes it easier for the bag attached to it to move along the inclined side panel and detach until it reaches the other end of the bin for sealing, making the operation simpler.

[0036] In one optional embodiment, the movable part is provided with a positioning part, such that when the garbage bag is placed on the movable part, the positioning part positions the opening of the garbage bag, and when the pull rope is pulled, the pull rope causes the opening of the garbage bag to disengage from the positioning part.

[0037] The advantage is that the positioning part ensures that the opening of the garbage bag can be securely and reliably installed on the movable part, thus preventing the opening of the garbage bag from detaching from the movable part when the user disposes of the garbage.

[0038] In one optional embodiment, the positioning part has a circular hole structure, which is suitable for inserting the opening of the garbage bag into the positioning part for positioning.

[0039] The advantages are that the structure is simple and easy to manufacture, and the way the garbage bag opening is positioned is simple and easy to operate.

[0040] In one optional embodiment, the side of the bucket cover is provided with a pull-out opening, which is adapted to be opposite to the through-hole after the bucket cover is closed with the side wall of the bucket body, so that the free end of the drawstring provided in the through-hole extends out from the pull-out opening.

[0041] The advantage is that a pull-out opening is provided on the cover corresponding to the outlet, allowing users to close the garbage bag without removing the cover by pulling the drawstring. This prevents the pungent odor inside the garbage bag from directly hitting the user during the closing process, resulting in a better user experience.

[0042] In one optional embodiment, the bin cover includes an outer bin and a bin lid. The top of the outer bin is provided with a dispensing opening corresponding to the bin opening. The bin lid is rotatably installed at the dispensing opening. The pull-out opening is provided on the outer bin. The outer bin is also provided with a rope outlet. One end of the rope outlet is connected to the pull-out opening, and the other end is connected to the dispensing opening, so that after the garbage bag is closed, the rope can move along the rope outlet to the dispensing opening.

[0043] The advantage is that the drawstring outlet allows the drawstring to be moved out through the outlet to the garbage disposal opening after the garbage bag is closed, making it easier to remove the garbage bag without removing the cover. This makes the operation simpler and provides a better user experience.

[0044] In one alternative embodiment, the vent is located at the bottom of the side wall of the bin, and when the bin cover moves toward the bottom of the bin to its limit position, the bin cover is located above the vent, which is suitable for allowing air passing through the vent to be discharged to the outside of the trash can.

[0045] The advantage is that the cover is located above the vent, so that the vent is not blocked when the cover is installed on the bin and after installation, and is always in a state of communication with the outside, thus facilitating the timely discharge of air to the outside of the trash can.

[0046] In one optional embodiment, the distance between the barrel cover and the barrel body and the distance between the barrel cover and the protruding part are both H, wherein H≤5mm.

[0047] The advantage is that it makes the distance between the cover and the body of the bin equal to the distance between the cover and the outlet, thus ensuring that the side wall surfaces of the body and the outlet are on the same plane. This makes the cover installation smoother and avoids jamming. It also facilitates production and processing. When the distance H > 5mm, the distance between the cover and the body is large. During installation, a lot of air inside the cover will leak to the outside of the body along this distance. As a result, there is not enough air inside the cover to allow the garbage bag to open and adhere to the side wall of the body, resulting in poor bag laying effect. When the distance H ≤ 5mm, the cover and body are installed more smoothly, and the amount of air leakage inside the cover is relatively small. This results in better bag laying effect and is also easier for users to operate. Attached Figure Description

[0061] 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.

[0062] like Figure 2-8 As shown, this utility model relates to a trash can, including a can body 10 with a can opening 101. The can body 10 has an exhaust hole 102 and a can cover 20, which is used to expand and unfold a trash bag 30 with a drawstring 31 inside the can body 10 when it is closed on the can opening 101 and gradually moves towards the bottom of the can body 10. The exhaust hole is used to discharge the air between the trash bag 30 and the can body 10. A through-hole 11 is provided on the side wall 103 of the can body 10. When the trash bag 30 is laid inside the can body 10, the free end of the drawstring 31 passes through the through-hole 11 from inside the can body 10 to the outside of the can body 10, so that it can be driven to move away from the can body 10 to close the opening of the trash bag 30.

[0063] like Figure 1 As shown in the prior art, existing trash cans have an outwardly protruding mounting plate 12 on the side wall 103 of the can body 10 for positioning the drawstring 31, so that the opening of the trash bag 30 is turned outward and fitted onto the opening 101 of the can. The drawstring 31 is located in the through part 11 of the mounting plate 12. Because of the mounting plate 12 protruding outward from the side wall 103 of the can body 10, the can cover 20 needs to make room for the mounting plate 12 when it is fitted. Therefore, the gap between the can cover 20 and the can body 10 is relatively wide. When the can cover 20 moves towards the bottom of the can body 10, some of the air inside the can cover 20 will be discharged out of the can body 10 along the gap 14 between the can cover 20 and the can body 10. This means that the other part of the air pressed into the trash bag 30 by the can cover 20 is insufficient to make the trash bag 30 fit tightly against the inner wall of the can body 10. That is, the efficiency of the trash bag 30 expanding and unfolding is poor, which affects the user experience.

[0064] The bin body 10 is used to form a container for storing garbage. The opening 101 is located at the top of the bin body 10. Generally, users will put garbage bags 30 inside the bin body 10 and usually turn the opening of the garbage bag 30 outward and put it on the opening 101. The bin body 10 has an exhaust hole 102, which is used to expel the air between the garbage bag 30 and the bin body 10, so that the garbage bag 30 is attached to the side wall 103 of the bin body 10, and the garbage bag 30 is in an unfolded state.

[0065] The cover 20 is shaped like a "cover" and has an opening. The cover 20 can be movably closed onto the opening 101 of the bin to open or close the opening 101. When the cover 20 moves toward the bottom of the bin body 10, the air inside the cover 20 is gradually forced into the garbage bag 30, causing the garbage bag 30 to expand and unfold so that the garbage bag 30 can adhere to the side wall 103 of the bin body 10. The air between the garbage bag 30 and the bin body 10 is discharged to the outside of the bin body 10 as the cover 20 moves toward the bottom of the bin body 10, so that the garbage bag 30 can adhere to the inner side wall 103 of the bin body 10.

[0066] The garbage bag 30 used in this example is a drawstring garbage bag 30. The drawstring garbage bag 30 is existing technology, and its specific structure will not be described in detail here. Generally, there is a notch at the bag opening, and the free end of the drawstring 31 is located in the notch. The free end of the drawstring 31 can be pulled away from the notch, so that the drawstring 31 seals the bag opening. The free end of the drawstring 31 is the part of the drawstring 31 located in the notch. This part can be pulled out of the notch by the user to pull the drawstring 31 out of the notch. In this example, the bag opening of the garbage bag 30 is folded outward and installed on the bin opening 101, so that when the free end of the drawstring 31 is pulled away from the bin body 10, the bag opening of the garbage bag 30 is sealed.

[0067] The through-hole 11 is used to position the drawstring 31. The through-hole 11 is provided on the side wall 103 of the bin body 10, and the free end of the drawstring 31 can pass through the through-hole 11 from inside the bin body 10 to outside the bin body 10. This means that the structure for positioning the drawstring 31 does not need to extend from the side wall 103 of the bin body 10 away from the bin body 10. This allows the gap between the bin cover 20 and the bin body 10 to be set small enough when the bin cover 20 moves relative to the bin body 10, or even the bin cover 20 can be fitted tightly against the side wall 103 of the bin body 10. When the bin cover 20 moves toward the bottom of the bin body 10, the amount of air lost in the bin cover 20 along the gap 14 between the bin cover 20 and the bin body 10 is small. This allows most of the air in the bin cover 20 to act on the garbage bag 30, so that the garbage bag 30 can better adhere to the inner wall of the bin body 10, resulting in a better user experience.

[0068] In one optional embodiment, the through-hole 11 is a through hole penetrating the side wall 103. The free end of the drawstring 31 passes through the through hole from inside the bucket 10 to the outside of the bucket 10. When the through-hole 11 is set as a through hole, the through-hole 11 does not need to be provided with an extension structure on the side wall 103 of the bucket 10 to position the drawstring 31. This allows the bucket cover 20 to approach or even be close to the side wall 103 of the bucket 10 and move towards the bottom of the bucket 10. This makes the gap 14 between the bucket cover 20 and the bucket 10 small enough, further reducing the amount of air loss inside the bucket cover 20. The garbage bag 30 is laid better. This example does not limit the shape of the through hole. It can be circular, polygonal, or irregular, as long as the through hole allows the free end of the drawstring 31 to pass through.

[0069] In one optional embodiment, the protruding part 11 is a strip-shaped groove with an open top formed by the downward indentation of the top of the side wall 103. When the free end of the drawstring 31 is driven to move, the opening of the garbage bag 30 is closed, and the drawstring 31 moves out of the strip-shaped groove from the opening, so that the garbage bag 30 can be moved out of the bin 10. The strip-shaped groove is provided so that the user can pull the free end of the drawstring 31 and the end near the bag body, so that the part between the two ends of the drawstring 31 that are pulled can be inserted into the strip-shaped groove from top to bottom to position the drawstring 31. This makes the operation more convenient for the user and also facilitates the removal of the drawstring 31 and the garbage bag 30 after it has been closed. In this example, the preferred strip-shaped groove is vertical to facilitate the insertion and removal of the drawstring 31 and avoid the drawstring getting stuck.

[0070] In an alternative embodiment, a mounting plate 12 is provided at the top of the side wall 103 and extends away from the barrel body 10. The穿出部11 is provided on the mounting plate 12. The mounting plate 12 is used to form the substrate of the穿出部11. When the mounting plate 12 is provided at the top of the side wall 103, it does not occupy the space of the side wall 103 of the barrel body 10, so that the barrel cover 20 can be close to or even close to the side wall 103 of the barrel body 10 and move towards the bottom of the barrel body 10. As a result, the gap 14 between the barrel cover 20 and the barrel body 10 is small enough, further reducing the air loss in the barrel cover 20, and the laying effect of the garbage bag 30 is better. At the same time, it does not damage the overall structure of the barrel body 10, making the barrel body 10 more beautiful. In this example, preferably, the穿出部11 is recessed from the side of the mounting plate 12 away from the barrel body 10 towards the center of the mounting plate 12, so that the drawstring 31 inlet and outlet of the穿出部11 are provided at the top of the mounting plate 12, which is convenient for the user to position the drawstring 31 in the穿出部11 from the top of the trash can. It can be understood that the穿出部11 can be formed as a circular hole and directly provided on the mounting plate 12, or the穿出部11 can be recessed from other side parts of the mounting plate 12 towards the center of the mounting plate 12.

[0071] Preferably in this example, the outer side wall 103 of the mounting plate 12 and the outer side wall 103 of the barrel body 10 are in the same plane, so that the outer surface of the barrel body 10 is smooth without steps. When the barrel cover 20 is sleeved and installed with the barrel body 10, the barrel cover 20 can smoothly move towards the bottom of the barrel body 10, avoiding jamming during the movement of the barrel cover 20, and the user experience is better.

[0072] It can be understood that the inner side wall 103 of the mounting plate 12 and the inner side wall 103 of the barrel body 10 are in the same plane, so that the outer surface of the barrel body 10 is smooth without steps, and the user will not be stuck when taking out the garbage bag 30 filled with garbage.

[0073] In an alternative embodiment, a mounting groove 13 is provided at the top of the side wall 103 and recessed downward. The bottom of the mounting groove 13 extends away from the barrel body 10 to provide the mounting plate 12. When the mounting plate 12 is provided in the mounting groove 13 at the top of the side wall 103, the mounting plate 12 is not completely protruded from the top of the side wall 103, so that the distance between the top of the barrel cover 20 and the top of the side wall 103 can be reduced, making the sleeved installation of the barrel cover 20 and the barrel body 10 closer. Preferably in this example, the side wall 103 provided with the mounting plate 12 is formed in a "mountain" shape.

[0074] In one optional embodiment, the mounting plate 12 includes a base plate 122 and an extension plate 121. One side of the base plate 122 is fixedly connected to the bottom of the mounting groove 13, and the other side is fixedly connected to the extension plate 121. The through-hole 11 is provided on the extension plate 121, dividing the mounting plate 12 into two parts. The base plate 122 is used to connect the extension plate 121 and the barrel 10. Because the extension plate 121 with the through-hole 11 needs to withstand a certain tension when the draw rope 31 is pulled, the base plate 122 can make the extension plate 121 more firmly connected to the barrel 10. The extension plate 121, the base plate 122 and the barrel 10 can be integrally formed, or they can be assembled and fixed by a connecting structure. In this example, the extension plate 121 and the base plate 122 are preferably "convex" shaped structures, which makes the horizontal width of the base plate 122 larger and its connection length with the barrel 10 longer, making the connection between the mounting plate 12 and the barrel 10 more firm and reliable.

[0075] In one optional embodiment, the thickness of the base plate 122 and the extension plate 121 is greater than the wall thickness of the bucket body 10. Since the protruding part 11 is located on the extension plate 121, when the drawstring 31 is pulled, at least the extension plate 121 will be subjected to a certain tension. Therefore, when the wall thickness of the base plate 122 and the extension plate 121 is set to be thicker than that of the bucket body 10, the base plate 122 and the extension plate 121 will be stronger and more stable, and less prone to shaking. In this example, the thickness of the base plate 122 and the extension plate 121 is preferably the same, that is, the thickness of the mounting plate 12 is greater than that of the bucket body 10, which facilitates the forming of the mounting plate 12. Preferably, the thickness difference between the mounting plate 12 and the bucket body 10 is maintained between 1mm and 10mm, which enhances the strength of the mounting plate 12 without affecting the smooth removal of the garbage bag 30. In order to ensure that the garbage bag 30 filled with garbage can be easily removed, an inclined transition surface can be provided at the part where there is a height difference between the bucket body 10 and the mounting plate 12 to prevent the garbage bag 30 from getting stuck when it is removed.

[0076] In one optional embodiment, the base plate 122, the extension plate 121 and the barrel body 10 are integrally formed, which facilitates production and assembly. The integral forming improves the strength of the base plate 122 and the extension plate 121. When the draw rope 31 is pulled, the base plate 122 and the extension plate 121 are more stable and less prone to shaking.

[0077] In one optional embodiment, the mounting plate 12 and the barrel body 10 are separately formed and assembled. Because the mounting plate 12 is frequently subjected to the tension of the pull rope during use, the connection between the mounting plate 12 and the barrel body 10 is prone to fatigue and damage after long-term use. When the mounting plate 12 and the barrel body 10 are separately formed and assembled, it is convenient to replace the mounting plate 12. The assembly method can be a connection method such as a buckle, screw, or bolt.

[0078] In an optional embodiment, a gap 14 is provided between the side wall 103 of the mounting groove 13 and the mounting plate 12. The gap 14 is used so that when the bag opening of the garbage bag 30 is fitted onto the outside of the bin body 10, a portion of the bag opening adjacent to the drawstring 31 can enter the bin body 10 through the gap 14, so that the free end of the drawstring 31 can pass through the through-hole 11 from inside the bin body 10 to the outside of the bin body 10. When the gap 14 is provided between the side wall 103 of the mounting groove 13 and the mounting plate 12, it is convenient for a portion of the bag opening to enter the bin body 10 through the gap 14 when the garbage bag 30 is folded over and fitted onto the top of the bin body 10, thereby facilitating the passing of the drawstring 31 through the outside of the bin body 10.

[0079] In one optional embodiment, the two opposite sidewalls 103 of the mounting groove 13 are each provided with a gap 14 between them and the mounting plate 12, so that there are gaps 14 on both sides of the mounting plate 12. When the garbage bag 30 is folded over and installed on the top of the bin 10, the two positions of the bag opening adjacent to the drawstring 31 pass through the gaps 14 and enter the bin 10, so that the mounting plate 12 is located outside the bag opening, thereby facilitating the drawstring 31 to pass through the protrusion 11 on the mounting plate 12. In this example, the two gaps 14 are preferably evenly provided on both sides of the protrusion 11.

[0080] In one optional embodiment, the bin body 10 further includes a movable part 15 disposed on the side of the bin opening 101. When the garbage bag 30 is fitted onto the bin opening 101, the garbage bag 30 is at least partially disposed on the movable part 15. When the free end of the drawstring 31 is driven to move away from the bin body 10, the movable part 15 moves or deforms, causing the opening of the garbage bag 30 to detach from the movable part 15 and be closed. The movable part 15 is provided so that when the drawstring is pulled, the opening of the bag disposed on the movable part 15 can detach from the movable part 15 through the movement or deformation of the movable part 15, thereby facilitating the detached opening of the bag to move towards the protrusion part 11 for closing.

[0081] Understandably, the bin body 10 may have an inclined slope (not shown in the figure) on the side wall 103 opposite to the through part 11. This inclined slope can remain stationary during the drawstring 31 closing process. When the bag opening of the garbage bag 30 is fitted onto this inclined slope, the bag opening can be driven by the drawstring 31 to slide off the inclined slope and disengage from the inclined slope to complete the closing of the garbage bag 30.

[0082] In one optional embodiment, the movable part 15 and the protruding part 11 are arranged opposite to each other. When the drawstring 31 is pulled at the protruding part 11, it can quickly act on the movable part 15, so that the bag opening on the movable part 15 can be closed in the direction close to the protruding part 11 after it is detached, resulting in a better user experience.

[0083] Understandably, the movable part 15 can also be provided on the side wall 103 of the bin body 10 that does not have the through part 11. For example, the side wall 103 adjacent to the side wall 103 with the through part 11 only needs to ensure that the bag opening of the garbage bag 30 provided on the movable part 15 is detached when the drawstring 31 is pulled.

[0084] In one optional embodiment, the movable part 15 is a flexible wall. When the drawstring 31 is pulled, the garbage bag 30 disposed on the movable part 15 causes the movable part 15 to deform, so that the opening of the garbage bag 30 gradually detaches from the movable part 15 and is closed. The flexible wall is the side wall 103 that can deform under force. The flexible wall is provided so that when the drawstring 31 is pulled, the drawstring 31 can drive the flexible wall to deform, so that the opening of the garbage bag 30 disposed on the flexible wall can detach. The flexible wall has good elasticity and toughness, and it can quickly and automatically return to its original shape after being deformed. To facilitate the next bagging and drawstring 31 closing operation, the flexible wall in this example is preferably made of a flexible material, including but not limited to rubber, silicone, TPE, TPR, PP, etc. The deformation mode of the flexible wall in this example is that it remains roughly vertical in the initial state, and when driven by force, the roughly vertical flexible wall will bend and deform in the direction of force so that the bag opening of the garbage bag 30 placed on it can be easily removed. The flexible wall and the bin body 10 can be integrally injection molded, or they can be connected and fixed by connectors, such as buckles, glue, screws, etc.

[0085] In one optional embodiment, the movable part 15 is a side plate rotatably connected to the side wall 103 of the bin body 10. When the drawstring 31 is pulled, the garbage bag 30 on the movable part 15 drives the movable part 15 to rotate toward the protruding part 11, so that the opening of the garbage bag 30 gradually detaches from the movable part 15 and is closed. The side plate is provided so that when the drawstring 31 is pulled, the drawstring 31 can drive the side plate to rotate so that the opening of the garbage bag 30 on the side plate can detach. The side plate is rotatably connected to the side wall 103 of the bin body 10, so that the side plate can rotate to an inclined position, thereby facilitating the movement of the bag opening on it along the inclined side plate until it moves to the other end of the bin body 10 for closure, making the operation simpler. In this example, the side plate is preferably connected to the bin body 10 by a pivot. In order for the side plate to return to its original position after rotation, a reset component is provided between the side plate and the bin body 10. The reset component includes, but is not limited to, a spring and silicone. The rubber, counterweight, and reset component can be located at the pivot or between the side plate and the barrel 10. In this example, the outer surface of the side plate is preferably smooth to facilitate the bag opening sliding off along its outer surface.

[0086] In one optional embodiment, the movable part 15 is provided with a positioning part 151, so that when the garbage bag 30 is placed on the movable part 15, the positioning part 151 positions the opening of the garbage bag 30. When the pull rope is pulled, the pull rope causes the opening of the garbage bag 30 to disengage from the positioning part 151. The positioning part 151 is provided so that the opening of the garbage bag 30 can be securely and reliably installed on the movable part 15, so as to prevent the opening of the garbage bag 30 from detaching from the movable part 15 when the user disposes of garbage.

[0087] In one optional embodiment, the positioning part 151 has a circular hole structure, which is suitable for inserting the opening of the garbage bag 30 into the positioning part 151 for positioning. The structure is simple and easy to manufacture. At the same time, the method of positioning the opening of the garbage bag 30 is simple and easy to operate. In order to improve the positioning effect of the garbage bag 30, several teeth can be set in the circular hole so that the garbage bag 30 is fixed by the teeth when it is inserted into the circular hole.

[0088] Understandably, the positioning part 151 can also be a clamping structure, for example, clamping the opening of the garbage bag 30 with two clamping pieces.

[0089] Understandably, the positioning part 151 can also be an adhesive structure, for example, positioning the garbage bag 30 by adhesive.

[0090] In one optional embodiment, the side of the cover 20 is provided with a pull-out opening 21, which is suitable for the cover 20 to be closed with the side wall 103 of the body 10 after it is closed. The pull-out opening 21 is opposite to the through-hole 11, so that the free end of the drawstring 31 provided in the through-hole 11 extends out of the pull-out opening 21. The pull-out opening 21 is opened on the cover 20 at the position corresponding to the through-hole 11, so that the user can close the mouth of the garbage bag 30 by pulling the drawstring without removing the cover 20, so as to prevent the pungent odor inside the garbage bag 30 from directly hitting the user during the closing process, and the user experience is better. This example does not limit the shape of the pull-out opening 21, which can be circular, polygonal or irregular hole shape.

[0091] In one optional embodiment, the bin cover 20 includes an outer bin 22 and a bin lid 23. The top of the outer bin 22 is provided with a disposal opening 201 corresponding to the bin opening 101. The bin lid 23 is rotatably installed at the disposal opening 201. A pull-out opening 21 is provided on the outer bin 22. The outer bin 22 is also provided with a rope outlet 24. One end of the rope outlet 24 is connected to the pull-out opening 21, and the other end is connected to the disposal opening 201, so that after the garbage bag 30 is closed, the drawstring 31 can be moved along the rope outlet 24 to the disposal opening 201. The rope outlet 24 is provided so that after the garbage bag 30 is closed, the drawstring 31 can be moved out through the rope outlet 24 to the garbage disposal opening 201, so that the garbage bag 30 can be taken out without removing the bin cover 20, making the operation simpler and the user experience better.

[0092] In one optional embodiment, the vent 102 is located at the bottom of the side wall 103 of the bin body 10. When the bin cover 20 moves to its limit position toward the bottom of the bin body 10, the bin cover 20 is positioned above the vent 102, which allows air passing through the vent 102 to be discharged to the outside of the trash can. The bin cover 20 being positioned above the vent 102 ensures that the vent 102 is not obstructed during and after installation with the bin body 10, and remains in communication with the outside. This facilitates the timely exhaust of air to the outside of the trash can. In this example, the preferred bin body 10 includes a base and an inner bin, which are assembled by snap-fit ​​or interference fit. The bottom of the inner bin is provided with an exhaust hole 102, and a stepped surface is provided above the exhaust hole, so that the bin cover 20 abuts against the stepped surface when it moves toward the bottom of the bin body 10 to its limit position, which can remind the user that the bin cover 20 is installed in place, and at the same time, the overall appearance is more beautiful. In this example, a number of exhaust holes 102 are provided, which are arranged in a strip on the bottom side wall 103 of the bin body 10.

[0093] In one optional embodiment, the distance between the cover 20 and the barrel body 10 and the distance between the cover 20 and the through-hole 11 are both H, where H ≤ 5mm. This ensures that the distance between the cover 20 and the barrel body 10 and the distance between the cover 20 and the through-hole 11 are equal, thereby making the surface of the side wall 103 of the barrel body 10 and the surface of the side wall 103 of the through-hole 11 coplanar. This makes the cover 20 easier to install, preventing jamming, and also facilitates manufacturing. When the spacing H > 5mm, the gap between the cover 20 and the body 10 is relatively large. When the cover 20 is installed, a lot of air inside the cover 20 will leak to the outside of the body 10 along this gap. As a result, the air inside the cover 20 is insufficient to allow the garbage bag 30 to open and adhere to the side wall 103 of the body 10, resulting in a poor bag-laying effect. When the spacing H ≤ 5mm, the cover 20 and the body 10 are installed more smoothly, and the amount of air leakage inside the cover 20 is relatively small. The bag-laying effect is better, and it is also easier for the user to operate.

[0094] 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.
