[0043] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0044] The utility model constructs a garbage bin 100. The garbage bin 100 is provided with a garbage bag supporting structure 1 for supporting the garbage bag and helping to put on the bag and / or close the garbage bag.

[0045] Optionally, the garbage bag support structure 1 can be formed at the cover assembly of the garbage can 100, or on the barrel body 2 of the garbage can 100, or on the cover assembly and the barrel body 2 of the garbage can 100 respectively, which is not specifically limited here. It can be understood that the cover assembly can include a barrel cover 4 and a cover ring 3 between the barrel cover 4 and the barrel body 2. Of course, the cover assembly can also include only the barrel cover 4, or only the cover ring 3, which can be adjusted according to the type of garbage can, which includes open-top garbage cans and covered garbage cans. In some embodiments, please refer to Figure 1 The garbage bag supporting structure 1 may be formed at the cover assembly of the garbage can 100 , and may include a first supporting portion 11 and a hinge portion 12 .

[0046] Among them, you can refer to Figure 2 The first support portion 11 is provided with a clearance notch 111; Figure 4 The hinge portion 12 is rotatably arranged at the clearance notch 111, and has a natural state and a flipped state; in the natural state, Figure 4 As shown, the hinge portion 12 and the first support portion 11 together form a ring structure that supports the folded garbage bag; in the flipped state, the Figure 5 The hinge portion 12 is rotated to open the clearance notch 111 to release the support of the hinge portion 12 to the garbage bag.

[0047] For the convenience of explanation, the side of the first support portion 11 provided with the clearance notch 111 is referred to as the first side A, and the first support portion 11 also has a second side B opposite to the first side A. It can be understood that when the garbage bag is put into use, the user can fold the bag mouth of the garbage bag and place it on the annular structure surrounded by the loose-leaf portion 12 and the first support portion 11. In the process of placement, the loose-leaf portion 12 can be forced to flip in the direction of the second side B, which is equivalent to reducing the size of the annular structure in disguise, so that the garbage bag can be more easily placed on the annular structure.

[0048] After the garbage bag is placed, the edge of the bag opening of the garbage bag can be located at the periphery of the annular structure; when the garbage needs to be disposed of, the user can pull the edge of the bag opening of the garbage bag on the second side B outward, and the edge of the bag opening of the garbage bag on the first side A has a tendency to move toward the second side B, so that the hinge portion 12 flips toward the second side B, allowing the notch 111 to be opened; then, the bag body of the garbage bag on the first side A loses the support of the hinge portion 12, and moves toward the second side B, so that the bag opening of the garbage bag can be reduced or even closed. It can be seen that when the garbage bag needs to be packed, as long as one side of the garbage bag is pulled, the bag opening of the garbage bag is basically closed together, so that it is convenient to pack; moreover, this can effectively prevent the odor and bacteria in the garbage bag from escaping from the garbage bag.

[0049] In particular, when the garbage bag is a drawstring type garbage bag, the drawstring on one side of the drawstring type garbage bag can be set at a peripheral position of the second side B; in actual use, the bag opening of the drawstring type garbage bag can be tied at the second side B of the first support part 11 under the action of the drawstring, so as to achieve a one-pull packaging effect, and the drawstring type garbage bag can be sealed without opening the lid 4 of the garbage can 100 (refer to Example 2).

[0050] In some embodiments, reference may be made to Figure 4 The garbage bag supporting structure 1 further comprises a hinge mechanism 16 for rotatably mounting the hinge portion 12 at the clearance notch 111 , and the hinge portion 12 can be rotated in a direction from the first side A to the second side B through the hinge mechanism 16 .

[0051] In some embodiments, reference may be made to Figure 6 The garbage bag supporting structure 1 further includes a reset mechanism 17 for driving the hinge portion 12 to reset from the flipped state to the natural state. The reset mechanism can be arranged at the hinge mechanism 16 .

[0052] In some embodiments, reference may be made to Figure 1 The shape of the annular structure shared by the loose-leaf portion 12 and the first supporting portion 11 can be an elliptical, circular, square or waist-shaped hole shape, etc.; at the same time, the loose-leaf portion 12 and the first supporting portion 11 also jointly define an opening, and the shape of the opening is adapted to the annular structure, which can be an elliptical, circular, square or waist-shaped hole shape, etc.

[0053] In some embodiments, reference may be made to Figure 2 , 4 The edges of the first support portion 11 on both sides of the clearance notch 111 can be beveled edges, and the beveled edges extend upward from the bottom of the clearance notch 111 toward the other side opposite to the side of the first support portion 11 where the clearance notch 111 is provided, so as to facilitate pulling the edge of the bag opening of the drawstring garbage bag on the first side A toward the second side B.

[0054] Secondly, if Figure 2 As shown, the height and maximum width of the clearance gap 111 are sufficient to allow the edge of the bag opening of the garbage bag at the first side A to move toward the second side B when it leaks out of the clearance gap 111. Optionally, the width of the clearance gap 111 can be gradually increased from bottom to top, which can play a guiding role and effectively prevent the edges of the first support portion 11 on both sides of the clearance gap 111 from hindering the movement of the edge of the bag opening of the garbage bag.
