As shown in fig. 1 to 7, according to a first aspect of the embodiment of the present utility model, a lid 10 of a trash can 100 is provided, and the lid 10 is applied to the trash can 100, as shown in fig. 1 to 6, wherein fig. 1 schematically illustrates a structural schematic view of the trash can 100 according to the embodiment of the present utility model, fig. 2 is a partially enlarged structural view at a in fig. 1, fig. 3 is a structural schematic view of the trash can 100 illustrated in fig. 1 at a second viewing angle, fig. 4 is a partially enlarged structural view at B in fig. 2, fig. 5 is a structural schematic view of the trash can 100 illustrated in fig. 1 at a third viewing angle, and fig. 6 is a partially enlarged structural view at C in fig. 5. The trash can 100 includes a can body 20 and a can cover 10, the can cover 10 includes a cover plate 11, a driving member 12, and a gear assembly 13, the cover plate 11 is rotatably connected to the can body 20, and the cover plate 11 has a first position in which the cover plate 11 closes the can body 20, and a second position in which the cover plate 11 opens the can body 20; the driving piece 12 is arranged on the cover plate 11, and the driving piece 12 is provided with an output gear 121; the gear assembly 13 is arranged on the barrel body 20; the output gear 121 is in driving connection with the gear assembly 13, driving the cover plate 11 to switch between a first position and a second position.

According to the barrel cover 10 of the dustbin 100, the driving piece 12 is arranged on the cover plate 11, the output gear 121 of the driving piece 12 is in transmission connection with the gear assembly 13, and the cover plate 11 is switched between the first position and the second position through the relative rotation of the output gear 121 and the gear assembly 13, so that the barrel body 20 can be closed or the barrel body 20 can be opened. Because the output gear 121 is in transmission connection with the gear assembly 13, the force arm is reduced, and the driving force to the cover plate 11 is larger under the condition that the driving member 12 outputs the same moment, so that the cover plate 11 can be turned over more easily, and the cover plate 11 can be opened more easily.

In the prior art, a multi-stage reduction gearbox is adopted, the moment arm of the gearbox can be lengthened after the multi-stage reduction, and the driving force to the cover plate 11 is reduced, so that the cover plate 11 is difficult to turn, and the cover plate 11 can be turned only by means of external force components such as torsion springs. The barrel cover 10 of the dustbin 100 adopts a structure that the output gear 121 of the driving piece 12 is directly connected with the gear component 13 in a transmission way, so that the output gear 121 and the gear component 13 can be directly meshed and connected, and the advantages and disadvantages are reduced, so that the driving force generated on the cover plate 11 is larger on the premise that the driving piece 12 outputs the same moment, the cover plate 11 is easier to turn over, and the cover plate 11 is easy to open or close.

It will be appreciated that the lid 10 of the present utility model is configured such that the lid 11 is flipped by relative movement between the output gear 121 and the gear assembly 13, thereby allowing the lid 11 to be switched between the first and second positions.

Here, the turning direction of the cover 11 has two directions, in which the opening direction of the cover 11 is counterclockwise, and the closing direction of the cover 11 is clockwise, which can be achieved by the bi-directional rotation of the driving member 12, that is, the bi-directional movement of the cover 11 is achieved by the bi-directional rotation of the output gear 121, so that the switching between the first position and the second position of the cover 11 can be achieved.

In the prior art, the output gear 121 of the driving member 12 is usually in transmission connection with a multi-stage reduction gearbox, and the multi-stage reduction structure of the gearbox can result in a longer moment arm, so that the cover plate 11 of the dustbin 100 can be opened by means of external force such as torsion springs. In this application, the output gear 121 of the driving member 12 is directly meshed with the gear assembly 13 for transmission, so that the moment arm can be reduced, and the driving force to the cover plate 11 is greater under the condition that the driving member 12 outputs the same moment, so that the cover plate 11 can be easily opened.

The gear parts 131 are distributed in an arc shape, so that the engagement connection with the output gear 121 can be realized, and the cover plate 11 can be turned over.

It should be noted that the turning angle of the cover 11 is limited, that is, the cover 11 is turned from the first position to the second position or turned from the second position to the first position. The angle may be 70 to 90 degrees, that is, the cover 11 is turned over 70 degrees from the first position to the second position, or the cover 11 is turned over 90 degrees from the first position to the second position, or the cover 11 is turned over 80 degrees from the first position to the second position.

Note that, the width of the gear portion 131 is not limited to a range, but it is preferable that the width of the gear portion 131 is too large, and the strength of the gear portion 131 is reduced. For the size of the trash can 100 common in the related art, the width of the gear part 131 may be set in a range of 15 mm to 25 mm, for example, the width of the gear part 131 is 18 mm, where the width of the gear part 131 is the size of the outer side of the gear part 131 in the width direction.
