[0032] The waste garbage can further comprises a plurality of wheels 4 arranged on the bottom side of the barrel body 1.

[0033] It can be understood that in this embodiment, the number of wheels 4 is four, which are respectively located on the four sides of the bottom of the barrel body 1, and the two front wheels 4 are universal wheels, so as to facilitate turning when pushing the garbage can, and then the two rear wheels 4 can also be universal wheels.

[0034] As shown in Figure 4 The waste garbage can further comprises a driving assembly 6 for driving the closure cover 2 to rotate, the driving assembly 6 comprises a controller and a plurality of driving units; the driving unit comprises a driving piece arranged on the barrel body 1, a sliding frame 63 arranged on the output end of the driving piece, a plug rod 65 arranged on the sliding frame 63, and a recess hole 66 opened on the connecting piece 3, the plug rod 65 is inserted into the recess hole 66, and the controller is used to control the driving unit to open and close.

[0035] In the embodiment, the driving units are two, which can be increased or decreased appropriately in other embodiments. In the embodiment, the controller is an infrared sensor 61 arranged at the bottom of the outer wall of the barrel 1. Of course, in other embodiments, the controller can also be a button switch arranged at the upper portion of the barrel 1. In the embodiment, the driving member is an electric push rod 62, which can be a cylinder or the like in other embodiments. A battery can also be arranged at the inner side of the bottom of the barrel 1 to provide power for the air pump 51, the infrared sensor 61 and the electric push rod 62, and the battery can also be directly connected with an external power source through a wire. Specifically, when the operator needs to open the closure cover 2, the operator can approach the infrared sensor 61 with the foot, the infrared sensor 61 senses the foot of the operator, controls the electric push rod 62 to start, the output end of the electric push rod 62 is elongated to drive the sliding frame 63 to move upward, the sliding frame 63 moving upward drives the insertion rod 65 to move upward, the insertion rod 65 moving upward drives the connecting piece 3 to rotate, the connecting piece 3 rotating drives the closure cover 2 to rotate, so that the closure cover 2 is opened. Conversely, the operator approaches the infrared sensor 61 with the foot again, the infrared sensor 61 senses the foot of the operator again, controls the output end of the electric push rod 62 to retract, so that the closure cover 2 is closed.

[0039] It can be understood that, when the operator needs to put a garbage bag into the barrel 1 or take a garbage bag out of the barrel 1, and because the garbage can is too high to be operated by the operator, the operator can rotate the support piece 72 to rotate the support piece 72 away from the barrel 1, and rotate to contact with the baffle 75. Then, the barrel 1 is tilted, the support piece 72 is in contact with the ground to support the tilted barrel 1. At this time, the operator can put a garbage bag into the barrel 1 or take a garbage bag out of the barrel 1. After the garbage bag is taken out or put in, the operator can push the tilted barrel 1 to be vertical, and then reset the support piece 72.

[0040] When the support assembly 7 comprises two or more, the rotation shafts 73 of adjacent support assemblies 7 are connected to each other by a connecting rod 74.

[0041] It can be understood that in the present embodiment, the support assembly 7 is provided with two, which can be appropriately increased or reduced in other embodiments. When the operator rotates the support 72, the support 72 will drive the rotation shaft 73 thereon to rotate, and the rotation of the rotation shaft 73 will drive the connecting rod 74 to rotate, thereby causing the rotation shaft 73 of the other support assembly 7 to rotate. Thus, when one support 72 is rotated, all supports 72 will rotate synchronously.
