In fig. 3, the end of the drawstring 300 is fixedly connected to the movable portion 220, and the movable portion 220 is gradually away from its initial position no matter which direction a, b, c, d moves, and drives the drawstring 300 to move in the direction away from its initial position (for example, the initial position of the drawstring 300 is the position of the end of the drawstring 300 relative to the inner barrel 140), so as to draw the drawstring and close the garbage bag, and the present application does not limit the specific moving manner of the movable portion 220.

As shown in fig. 4, the end of the drawstring 300 is mounted on the mounting portion 103, and the movable portion 220 abuts against a middle portion of the drawstring 300. In fig. 4, the movable portion 220 is located on the left side of the drawstring 300, and when the motor 210 is activated, the movable portion 220 moves in the right direction (may move horizontally or obliquely) away from the initial position thereof, and the drawstring 300 is also driven to move in the direction away from the initial position thereof (for example, the initial position of the drawstring 300 is the position of the contact portion of the drawstring 300 and the movable portion 220 with respect to the inner barrel 140), so that the drawstring is drawn, and the closing of the garbage bag is completed.

It should be understood that if the drawstring 300 is not secured to the movable portion 220, the movable portion 220 will remain in contact with a portion of the drawstring 300 during the movement to allow the drawstring 300 to be drawn.

The drawstring is drawn to close the garbage bag in the above way, so that the movable part 220 has simple movable way and easy realization.

Specifically, fig. 6 is a schematic structural diagram of an electric necking device provided in an embodiment of the present application, as shown in fig. 2 and fig. 6, a rotating rod 230 is movably disposed on a garbage can body 100 (specifically, an inner barrel 140), a movable portion 220 is in transmission connection with a motor 210 through the rotating rod 230, and the rotating rod 230 rotates under the driving of the motor 210 to drive the movable portion 220 to move in a direction away from an initial position of the movable portion. At this time, the moving direction of the movable portion 220 corresponds to the moving direction indicated by the arrow b in fig. 3, and the movable portion 220 performs a rotational movement away from its initial position.

Further, the movable portion 220 is fixedly disposed at a first end of the rotating rod 230, and a second end of the rotating rod 230 is in transmission connection with the motor 210, at this time, the second end of the rotating rod 230 connected with the motor 210 is a rotation center, and the movable portion 220 rotates around the rotation center. The movable portion 220 may be disposed at the end of the rotating rod 230 or at the middle end of the rotating rod 230 to obtain different rotating ranges as long as the position of the movable portion 220 does not coincide with the position of the rotating center.

As shown in fig. 2 and 6, the movable portion 220 is in transmission connection with the motor 210 through a flexible transmission unit 250, and the flexible transmission unit 250 includes: a driving wheel 251 driven by the motor 210, a driven wheel 252 for driving the rotation rod 230, i.e., the movable portion 220, to rotate, and a flexible transmission member 253 for connecting the driving wheel 251 and the driven wheel 252. Illustratively, the flexible drive 253 can be a belt, chain, or like drive.

Because the rotational speed of motor 210 is usually very fast, so can't directly connect bull stick 230 and drive and rotate, through setting up flexible transmission unit 250, on the one hand can realize the deceleration, and on the other hand can make motor 210 and movable part 220 set up respectively on reasonable position, improves the space utilization of garbage bin and avoids the waste in space.

Further, a speed reduction unit 260 is further provided between the movable portion 220 and the motor 210. For example, as shown in fig. 6, the reduction unit 260 may be a plurality of reduction gears connected with the flexible transmission unit 250.

When the motor 210 is started to drive the movable portion 220 to start moving, acceleration is generated, when the rotating speed of the motor 210 is high, the initial acceleration is also high, a high traction force is generated instantaneously, and if the traction force is too high, the drawstring may be directly torn off, so that the closing of the garbage bag cannot be completed. The provision of the speed reduction unit 260 enables the movable portion 220 to rotate at a small angular velocity, thereby smoothly and smoothly completing the closing.

The present application is not limited to the specific arrangement of the speed reduction unit 260.
