[0034] A garbage can in a specific embodiment of the present disclosure, includes a cover turning mechanism. Referring to FIG. 1, the cover turning mechanism includes a housing 100, a cover 200, a first connecting rod 300 and a second connecting rod 400. Wherein the housing 100 is installed with a motor 110 and a rotating rod 120 is rotatably connected to the housing 100; the cover 200 covers on the housing 100 and the cover 200 is fixedly connected with the rotating rod 120; the first connecting rod 300 is fixedly connected with the motor 110; one end of the second connecting rod 400 is rotatably connected to the first connecting rod 300, and the other end of the second connecting rod 400 is rotatably connected to the cover 200; a torsional spring 500 is arranged on the rotating rod 120, the torsional spring 500 bears against the inner wall of the housing 100.

[0035] In use, with reference to FIG. 2, the motor 110 is activated and drives the first connecting rod 300 to rotate upward, and then the first connecting rod 300 drives the second connecting rod 400 to swing, so that the second connecting rod 400 drives the cover 200 to rotate around the axis of the rotating rod 120 and the cover 200 is opened. In the process of opening the cover 200, the torsional spring 500 bears against the inner wall of the housing 100 and provides a supporting torque, while eliminating the gap between the first connecting rod 300 and the second connecting rod 400. The forces at multiple nodes are in relatively balanced state which makes it easy and accurate for the motor 110 to control the angle, and makes the whole process of opening or closing the cover 200 more smoothly. In addition, the motor 110 reverses driving the first connecting rod 300 to turn down, so that the second connecting rod 400 swings and releases the support to the cover 200, and then the cover 200 is closed.

[0036] In some embodiments, in order to improve the fluency during the process of closing the cover 200, a clamping block 130 is arranged on the inner wall of the housing and a clamping slot is formed between a lower part of the clamping block 130 and the inner wall of the housing 100. A hook 510 is arranged at an end of the torsional spring 500 which bears against the inner wall of the housing 100. The hook 510 is clamped into the clamping slot so that the torsional spring 500 can be clamped with the clamping block 130. In the process of closing the cover 200, the rotating rod 120 rotates and the torsional spring 500 is reset. In the process of reset, the hook 510 is inserted into the clamping slot, and the hook 510 is connected with the clamping block 130, which causes the torsional spring 500 to generate a buffer force on the cover 200 and causes the cover 200 to be closed more smoothly. In addition, the hook 510 can also position the torsional spring 500.

[0037] In some embodiments of the present disclosure, the housing 100 is provided with an installation seat 140, and the installation seat 140 is provided with a first concave hole. The first connecting rod 300 is provided with a first convex, and the first convex is embedded into the first concave hole and rotates in the first concave hole. The first convex is in clearance fit with the first concave hole. The clearance fit avoids a hindrance caused by the mounting seat 140 to the first connecting rod 300 when the first connecting rod 300 is driven to swing, and makes the first connecting rod 300 swing more smoothly. In other embodiments, the first convex is arranged on the mounting seat 140, while the first connecting rod 300 is provided with a first concave hole.

[0038] In some embodiments of the present disclosure, one end of the second connecting rod 400 is provided with a first rotating shaft, the first connecting rod 300 is provided with a first perforation, the first rotating shaft is inserted in the first perforation, and the first rotating shaft is in interference fit with the first perforation. The gap between the first rotating shaft and the first perforation is reduced, such that in the process of the first connecting rod 300 driving the second connecting rod 400 to swing, it will avoid the gap causing the structural instability between the first connecting rod 300 and the second connecting rod 400, and improve the stability when the cover 200 is turning. In other embodiments, the first rotating shaft is arranged on the first connecting rod 300 and the first perforation is arranged on the second connecting rod 400.

[0039] In some embodiments of the present disclosure, a second perforation is provided at a bottom of the cover 200, the rotating rod 120 is inserted into the second perforation, and the rotating rod 120 is in interference fit with the second perforation. The rotating rod 120 is inserted in the second perforation via the interference fit. When the second connecting rod 400 drives the cover 200 to turn, the rotating rod 120 rotates in the housing 100, and the interference fit causes the rotating rod 120 to drive the torsional spring 500 to rotate and causes the torsional spring 500 to be in contact with the inner wall of the housing 100. The stability of the cover 200 is improved during rotation and the stuck situation is prevented.

[0040] In some embodiments of the present disclosure, one end of the second connecting rod 400 is provided with a second rotating shaft, a second concave hole is arranged on the cover 200, the second rotating shaft is inserted into the second concave hole and rotates relative to the second concave hole, and the second rotating shaft is in clearance fit with the second concave hole. In other embodiments, the circumference of is arranged on the cover 200, while the second rotating shaft is arranged on the second connecting rod 400.

[0041] In some embodiments of the present disclosure, the housing 100 is provided with a platform which is in contact with the first connecting rod 300 so that the first connecting rod 300 stops swinging. The first connecting rod 300 swings by the driving of motor 110, the cover 200 turns up through the second connecting rod 400. In the process of turning up, the first connecting rod 300 is in contact with a edge of the platform balance, such that the first connecting rod 300 cannot continue to swing, thereby the turning angle of the cover 200 is limited to prevent the cover 200 from turning excessively. With reference to FIG. 3, when the swing path of the first connecting rod 300 is blocked, the first connecting rod 300 stops swinging, and the second connecting rod 400 also stops swinging and begins to support the cover 200, such that avoiding the first connecting rod 300 and the second connecting rod 400 swinging to a dead point or avoiding a reversal that causes the cover 200 to not work properly.

[0042] In a specific embodiment of the present disclosure, the garbage can includes a cover turning mechanism, the cover turning mechanism includes a housing 100, a cover 200, a first connecting rod 300 and a second connecting rod 400.
