The linkage mechanism includes an actuation assembly 5 attached to the lid 2 and a clamping assembly 4 attached to the interior of the container 1. The clamping assembly 4 is configured to move between a clamping position and a released position. The clamping assembly 4 closes the central channel 11 when in the clamping position. The clamping assembly 4 opens the central channel 11 when in the released position. When the lid 2 is opened from a closed state, the actuation of the actuation assembly 5 allows the clamping assembly 4 to remain in the clamping position to close the central channel 11 to enclose a part of a garbage bag passing through the clamping assembly 4. When the lid 2 is closed from an open state, the actuation of the actuation assembly 5 allows the clamping assembly 4 to move from the clamping position to the released position and then to the clamping position to allow waste to reach an enclosed end of the garbage bag below the clamping assembly 4 and to enclose again the part of the garbage bag passing through the clamping assembly 4.

In the retracted position, the two actuating blocks 51 are respectively retracted into grooves on the actuating lever 50, so that when the lid 2 is opened from the closed state and causes the actuating lever 50 to move upward, the two actuating blocks 51 pass through between the two protrusions 410. In the stretched position, the two actuating blocks 51 are respectively stretched out of the grooves on the actuating lever 50, so that when the lid 2 is closed from the open state and causes the actuating lever 50 to move downward, the two actuating blocks 51 press against the two protrusions 410, to cause the two clamp plates 40 to move from the clamping position to the released position.

[0031] As shown in FIG. 1 and FIG. 2, the actuation assembly 5 further includes a first reset element 52, and the first reset element 52 is arranged between each of the actuating blocks 51 and the actuating lever 50. In the stretched position, the first reset element 52 is configured to allow a respective one of the two actuating blocks 51 to stretch out of a respective one of the grooves on the actuating lever 50.

The clamping assembly 4 is configured to move between a clamping position and a released position. The clamping assembly 4 closes the central channel 11 when in the clamping position. The clamping assembly 4 opens the central channel 11 when in the released position. When the lid 2 is opened from a closed state, the actuation of the actuation assembly 5 allows the clamping assembly 4 to remain in the clamping position to close the central channel 11 to enclose a part of a garbage bag passing through the clamping assembly 4. When the lid 2 is closed from an open state, the actuation of the actuation assembly 5 allows the clamping assembly 4 to move from the clamping position to the released position and then to the clamping position to allow waste to reach an enclosed end of the garbage bag below the clamping assembly 4 and to enclose again a part of the garbage bag passing through the clamping assembly 4.

[0036] As shown in FIG. 1, the container 1 includes a first housing therein, the first housing is connected to the opening 10 and forms an accommodating compartment which is circumferentially enclosed and has an opening at a top thereof, and the central channel 11 is defined by an inner surface of the first housing.

[0037] As shown in FIG. 1, a garbage bag box is arranged in the accommodating compartment.

[0038] As shown in FIG. 5, the clamping assembly 4 includes at least two clamp plates 40 attached to the interior of the container 1 and a transmission element 41 attached to the at least two clamp plates 40.

[0039] As shown in FIG. 6, the transmission element 41 includes four cranks 411 pivotably attached to the interior of the container 1 and a connecting rod 412 attached between each of the cranks 411 and a respective one of the clamp plates 40, each of the four cranks 411 is connected to a respective one of the four cranks 411 through a transmission rod, and two of the four cranks 411 respectively include protrusions 410.

[0040] As shown in FIG. 6, a cross-section of the transmission rod is rectangular.

[0041] As shown in FIG. 5, the clamping assembly 4 further includes a guide channel 413 arranged in the container 1, and the guide channel 413 is configured to define a trajectory for a movement of the at least two clamp plates 40 between the clamping position and the released position.

[0042] As shown in FIG. 5 and FIG. 9, the container 1 includes a second housing therein, and the guide channel 413 is arranged on a surface of the second housing opposite to the at least two clamp plates 40.

[0043] As shown in FIG. 5, two limiting pieces are arranged on the second housing, and a surface of each of two of the four cranks 411 opposite to a respective limiting piece of the two limiting pieces abuts against the respective limiting piece.

[0044] As shown in FIG. 5 and FIG. 6, the actuation assembly 5 includes an actuating lever 50 and two actuating blocks 51 attached to the actuating lever 50. An end of the actuating lever 50 is slidably attached to the lid 2. The two actuating blocks 51 are configured to move between a retracted position and a stretched position. In the retracted position, the two actuating blocks 51 are respectively retracted into grooves on the actuating lever 50, so that when the lid 2 is opened from the closed state and causes the actuating lever 50 to move upward, the two actuating blocks 51 pass through between the two protrusions 410. In the stretched position, the two actuating blocks 51 are respectively stretched out of the grooves on the actuating lever 50, so that when the lid 2 is closed from the open state and causes the actuating lever 50 to move downward, the two actuating blocks 51 press against the two protrusions 410, to cause the two clamp plates 40 to move from the clamping position to the released position.

[0045] As shown in FIG. 5, two connecting pieces are arranged on a surface of the lid 2 opposite to the actuating lever 50, and a bottom of each of the two connecting pieces is located in the container 1 and is slidably attached to the actuating lever 50.

[0046] As shown in FIG. 7 and FIG. 8, a guide groove is provided on a surface of the actuating lever 50 opposite to the second housing, a bump is arranged on a surface of the second housing opposite to the actuating lever 50, and the bump is slidably engaged in the guide groove.

[0047] As shown in FIG. 5, the actuation assembly 5 further includes a first reset element 52, and the first reset element 52 is arranged between each of the actuating blocks 51 and the actuating lever 50. In the stretched position, the first reset element 52 is configured to allow a respective one of the two actuating blocks 51 to stretch out of a respective one of the grooves on the actuating lever 50.

[0048] As shown in FIG. 5, the first reset element 52 is a torsion spring.

[0049] As shown in FIG. 5 and FIG. 6, the actuation assembly 5 further includes a second reset element 53 arranged between each of the actuating blocks 51 and the interior of the container 1. When the lid 2 is closed from the open state, the second reset elements 53 allow the two clamp plates 40 to move from the released position to the clamping position.

[0050] As shown in FIG. 6, the second reset element 53 is a torsion spring.
