[0034] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0035] like Figure 1-5 As shown, this embodiment provides an automatic baling trash can, including:

[0036] The inner bucket is 200mm in diameter and has an opening at the top for fitting inside the trash can.

[0037] The outer tub 100 has an opening at its lower end, which can cover the outside of the inner tub 200 from top to bottom.

[0038] The outer end of the packing rod 500 is hinged to the inner wall of the outer barrel 100.

[0039] A drawstring positioning component 800 is provided on the outer wall of the inner barrel 200 facing the packing rod 500. The drawstring positioning component 800 has a channel 810 for the packing rod 500 to pass through vertically. The drawstring positioning component 800 is provided with vertical slots 820 on both sides of the channel 810 for positioning the drawstring.

[0040] The elastic element 700 is disposed between the packing rod 500 and the inner wall of the outer barrel 100. It is used to provide a reaction force after the packing rod 500 applies force to it, so as to drive the packing rod 500 to return to its original position. In the initial state, the packing rod 500 is in an inclined state with the inside higher than the outside.

[0041] After the inner bucket 200 and the outer bucket 100 are assembled, the packing rod 500 is located below the drawstring positioning part 800, and the inner end of the packing rod 500 abuts against the outer wall of the inner bucket 200; preferably, the trash can is an injection molded part, and the inner end of the packing rod 500 is wrapped with a soft rubber layer. During the process of the outer bucket 100 covering the inner bucket 200 from top to bottom, the soft rubber layer can prevent the inner end of the packing rod 500 from making hard contact with the trash bag.

[0042] This design is for convenient closure and packaging of drawstring garbage bags. The usage steps are as follows:

[0043] Bag making: When the drawstring garbage bag is put into the inner bucket 200, fold the top of the garbage bag over and put it on the top outer wall of the inner bucket 200, and then insert the drawstring into the vertical slot 820 of the drawstring positioning part 800.

[0044] Bag pressing: Cover the outer barrel 100 from top to bottom over the outer side of the inner barrel 200, so that the packing rod 500 moves through the channel 810 to below the drawstring positioning part 800;

[0045] Lifting and Packing: Lift the outer bin 100, the packing rod 500 moves upward and hooks the drawstring. The objects inside the garbage bag press down on the garbage bag by their own weight. As the outer bin 100 moves upward, the drawstring is gradually lifted to pack the garbage bag. After packing, the outer bin 100 continues to move upward, and the packing rod 500 swings downward under the gravity of the objects inside the garbage bag, thereby separating the drawstring from the packing rod 500. The garbage bag remains in the inner bin 200 in a closed state.

[0046] This design enables automatic closing and zero-contact packaging of drawstring garbage bags, eliminating the need for additional drive structures. The packaging rod 500 can automatically detach itself based on the gravity of the contents of the garbage bag, resulting in a simpler structure. Throughout the entire process, the user only needs to manually put on the bag and secure the drawstring; all other steps are completed automatically when putting on the bag and lifting the outer bin 100, making it a seamless operation with convenient overall functionality and a superior user experience.

[0047] In this embodiment, the packing rod 500 is rotatably mounted on the inner wall of the outer barrel 100 via a shaft, and the elastic element 700 is a torsion spring A, which is fitted on the shaft and located below the bottom surface of the packing rod 500.

[0048] In the initial state, the packing rod 500 abuts against the upper end of the torsion spring A, and the lower end of the torsion spring A abuts against the inner wall of the outer bucket 100. As the packing rod 500 moves upward and hooks the drawstring, the reaction force provided by the drawstring causes the packing rod 500 to apply an external force to the upper end of the torsion spring A, and the torsion spring A provides a reaction force to the packing rod 500. As the outer bucket 100 moves upward, the drawstring is gradually lifted to achieve the sealing of the garbage bag.

[0049] During the assembly of the inner bucket 200 and the outer bucket 100, the inner end of the packing rod 500 first contacts the garbage bag and is blocked by the garbage bag, causing it to swing upward. At this time, the packing rod 500 separates from the upper end of the torsion spring A. Because the packing rod 500 has a small weight, the force exerted by the inner end of the packing rod 500 on the garbage bag is insufficient to cause the packing rod 500 to move the drawstring downward. Thus, the inner end of the packing rod 500 slides down the drawstring while closely adhering to the outer wall of the inner bucket 200. After sliding down the drawstring, the inner end of the packing rod 500 swings downward under its own weight until the inner end of the packing rod 500 abuts against the inner wall of the inner bucket 200.

[0050] In this embodiment, the shaft includes a shaft 510 and an outwardly protruding shaft 540;

[0051] The top surface of the outer end of the packing rod 500 is provided with a limiting protrusion 520. When the limiting protrusion 520 abuts against the inner wall of the outer barrel 100, the inner end of the packing rod 500 is at the upper limit position and the packing rod 500 is in an inclined state.

[0052] When the packing rod 500 is in an inclined state, its center of gravity is located between the outer convex shaft 540 and the inner end of the packing rod 500. During the process of fitting the inner barrel 200 and the outer barrel 100 together, the inner end of the packing rod 500 is suspended in the air after the rope is pulled. At this time, the inner end of the packing rod 500 can swing down under its own weight until it touches the inner wall of the inner barrel 200.

[0053] In this embodiment, two ear plates 530 are spaced apart on the bottom surface of the outer end of the packing rod 500, the shaft 510 is located between the two ear plates 530, the two ends of the shaft 510 are rotatably connected to the ear plates 530 on both sides respectively, and the torsion spring A is fitted on the shaft 510;

[0054] The protruding shaft 540 is mounted on the ear plate 530. The inner wall of the outer barrel 100 is provided with two connecting ears 110 on both sides of the packing rod 500. The connecting ears 110 are provided with shaft holes for rotating with the protruding shaft 540.

[0055] In this embodiment, to facilitate lifting the outer bucket 100, two handles 400 are symmetrically arranged on the outer periphery of the outer bucket 100. The handles 400 can be configured as slots for fingers to insert into or as handles for hands to grip.

[0056] In this embodiment, the drawstring positioning member 800 includes two convex plates 830 spaced apart, forming a channel 810 between the two convex plates 830, and the vertical slot 820 is formed on the top surface of the convex plate 830.

[0057] In this embodiment, a recessed clearance portion 230 is provided on the periphery of the top surface of the outer wall of the inner bucket 200. The recessed clearance portion 230 is located on the side of the inner bucket 200 facing the packing rod 500. The drawstring positioning member 800 is disposed in the recessed clearance portion 230. The design of the recessed clearance portion 230 makes it unnecessary for the outer bucket 100 to provide additional clearance space for the drawstring positioning member 800, making the overall structure of the trash can more compact.

[0058] In this embodiment, the inner tub 200 includes a base 220 and an upper tub 210. The bottom end of the upper tub 210 is connected to the base 220. Preferably, the upper tub 210 and the base 220 are connected by a snap-fit ​​connection to form the inner tub 200 assembly, which is simple to assemble.

[0059] In this embodiment, the bottom periphery of the upper cylinder 210 is provided with several vent holes 211 at intervals. After the bag is put on, as the outer barrel 100 covers the outer side of the inner barrel 200 from top to bottom, the garbage bag on the inner barrel 200 is filled with air from the inner cavity of the outer barrel 100 as it moves down, causing the garbage bag to quickly inflate. The air between the garbage bag and the inner barrel 200 is discharged through the vent holes 211, so that the garbage bag is automatically adsorbed on the inner wall of the inner barrel 200, so that the user does not need to flatten the garbage bag by hand.

[0060] In this embodiment, the outer periphery of the top surface of the base 220 has a support surface for supporting the outer bucket 100. The upper cylinder 210 is located inside the support surface. After the inner bucket 200 and the outer bucket 100 are fitted together, the bottom surface of the outer bucket 100 abuts against the support surface, and the vent 211 is covered by the outer bucket 100 to ensure that the vent 211 is not exposed, thereby improving the overall aesthetics of the trash can.

[0061] In this embodiment, the top of the outer bucket 100 is provided with a garbage disposal hole, and a top cover 300 is installed at the garbage disposal hole. One side of the top cover 300 is hinged to the outer bucket 100.

[0062] In this embodiment, a torsion spring B is provided at the hinge joint between the upper cover 300 and the outer bucket 100, a locking pin is provided on the bottom surface of the upper cover 300, and a push-button latch 600 that can cooperate with the locking pin is installed on the outer bucket 100. Preferably, the push-button latch 600 is a beetle latch, and both the push-button latch 600 and the latch are located on opposite sides of the hinge side. When it is necessary to close the garbage disposal hole, the upper cover 300 is driven to cover the garbage disposal hole, and then the top surface of the upper cover 300 opposite to the hinge side is pressed down, so that the push-button latch 600 and the latch lock together. When it is necessary to open the garbage disposal hole, the top surface of the upper cover 300 opposite to the hinge side is pressed down again, so that the push-button latch 600 and the latch lock separate, and the upper cover 300 automatically flips up under the action of the torsion spring B.
