[0032] Referring to the drawings in the specification, an intelligent drainage device includes a drain pipe 90, in which a water stop plug assembly 80 is provided. The outer periphery of the upper end of the water stop plug assembly includes a sealing ring 81 that can be sealed with the inner wall of the drain pipe. The lower end of the water stop plug assembly includes a connecting rod 82. The connecting rod can move up and down in the drain pipe with the water stop plug assembly. It also includes a driving rod 70 at one end that can swing up and down in the drain pipe. One end of the driving rod is connected to the connecting rod to achieve the lifting and lowering movement of the water stop plug assembly. It also includes a reversing device that can be connected to the other end of the driving rod. The reversing device can drive the driving rod to swing up and down intermittently. The connecting rod 82 that cooperates with the driving rod can be hinged or abutted with the driving rod. The driving rod can intermittently swing up and down when the rocker arm rotates in one direction, thereby achieving intermittent up and down movement of the moving part, and the connecting rod performs a linear lifting and lowering movement.

[0033] The automatic reversing device includes: a first turntable 10, a first connecting tooth 11 is provided on the first turntable, a second turntable 20, and a second connecting tooth 21 is provided on the second turntable; the first connecting tooth can be matched with the second connecting tooth to make the rotation directions of the first turntable and the second turntable opposite, and the two connecting teeth are in a meshing state; it also includes a rocker 30, which can rotate in one direction, that is, the drive motor does not need to realize forward and reverse rotation, reducing the requirements for the drive motor and also saving costs. A first rocker 12 that can rotate synchronously with the first turntable is provided, and a second rocker 22 that can rotate synchronously with the second turntable is provided. In use, the first rocker and the second rocker do not interfere with each other, and the rocker can intermittently match and connect with the first rocker and the second rocker so that the rocker drives the first turntable and the second turntable to intermittently reverse forward and reverse. Attached figure of the specification book, driving motor: in the first state: when the pendulum arm cooperates with the first pendulum arm, the pendulum arm drives the first pendulum arm to rotate, at this time the first turntable is reversed and the second turntable is forward, when the pendulum arm rotates to a certain angle, the first pendulum arm is separated from the pendulum arm, driving the motor, at this time a stroke is completed, and the MCU module will control the driving motor to stop rotating; in the second state: when the driving motor is started again, the pendulum arm drives the second pendulum arm to rotate, at this time the second turntable is reversed and the first turntable is forward, which is exactly opposite to the previous one, realizing reversal, when the pendulum arm rotates to a certain angle, the second pendulum arm is separated from the pendulum arm, at this time a stroke is completed, and the MCU module will control the driving motor to stop rotating again; in the third state: when the driving motor is started again, the driving motor; and then the above-mentioned first state action is performed, so that intermittent reversing can be achieved each time the unidirectional rotating pendulum arm is turned on.

[0034] Preferably, a driving motor 31 is further included, and the driving motor can be connected to the rocker arm, and the driving motor can drive the rocker arm to rotate in one direction.

[0035] Furthermore, the system includes an MCU module 40, which can be connected to a power source, and the drive motor can be connected to the MCU module, and the MCU module can be used to control the start and stop of the drive motor. It also includes a switch identifier 50, which can be connected to the MCU module, and is used to identify the rotation information of the first turntable or the second turntable, and send the rotation information to the MCU module to turn off the drive motor.

[0036] The switch identifier can be either inductive or mechanical. A mechanical type is described below: The outer periphery of the first or second turntable is provided with a matching module 60. The matching module can be a protrusion or a groove provided on the outer periphery of the first or second turntable. The embodiment shown in the figure is a protrusion. The switch identifier is provided with a switch contact 51 that can match the matching module. As the first or second turntable rotates, the matching module as a whole completes a rotational match with the switch contact. At this time, the switch identifier sends the rotation information to the MCU module to turn off the rotation of the drive motor. That is, before the rotation, the switch contact is located on one side of the matching module. After the rotation, the switch contact is located on the other side of the matching module. This realizes a signal collection. The switch identifier sends the signal to the MCU module to turn off the drive motor. The signal collection can be completed in both forward and reverse rotations. Of course, it can also be electronic, such as using infrared. When the two turntables are detected to have rotated a certain angle, the signal is collected and then sent to the MCU module to turn off the drive motor. The certain angle mentioned here can be the arc of the matching module, and the arc of the matching module is the same as the angle of the drive rod swing.

[0037] Furthermore, the MCU module is provided with a power interface 41 that can be connected to a power source. Of course, the MCU module can also be directly plugged into a power adapter or a battery, or it can also have a built-in rechargeable battery.

[0038] Preferably, a driving rod 70 is provided on the first turntable and / or the second turntable, and the driving rod can rotate synchronously with the first turntable and / or the second turntable. In use, the driving rod is connected to the first turntable.

[0039] More specifically, the present invention provides an automatic reversing device comprising a drive motor module, a gear set module, a swing arm for movement, a switch identifier (similar to a contact switch), and an MCU module. The drive motor module comprises a swing arm mounted on the rotating shaft of the drive motor. The swing arm's rotation sequentially drives the gear set, which comprises at least two rotating discs with connecting teeth, one of which is connected to the swing arm. Utilizing the principle of two connecting teeth meshing and moving in opposite directions, when the drive motor drives a first swing arm on a first rotating disc, the first rotating disc and the drive motor rotate in opposite directions, and the first swing arm rotates from a first state to a second state. The movement of the first rotating disc simultaneously drives the movement of the second rotating disc, thereby achieving co-directional rotation of the second rotating disc and the drive motor. When the swing arm disengages from the first swing arm, the drive motor switches to driving a second swing arm on the second rotating disc, causing the second rotating disc and the drive motor to rotate in opposite directions. The second rotating disc drives the movement of the first rotating disc, causing the first rotating disc to rotate in the same direction as the drive motor, and the first swing arm returns to its original position. The gear set comprises two rotating discs with connecting teeth, and the switch identifier identifies the position of the two rotating discs, thereby controlling the stopping of the drive motor. The principle of gear meshing and moving in opposite directions is then used to achieve automatic reversal of the mechanism, thereby controlling the back-and-forth movement of the moving part. In one embodiment, there is a matching module on the second turntable, so that a convex portion is formed at the position of the matching module, and the two sides of the convex portion are concave portions. The convex portion is connected to the switch identifier. The switch is coupled once, and the drive motor stops once. As shown in the figure, when the driving rod is at the highest point, the switch moves from one concave portion to the other side of the concave portion, and the drive motor stops; then, from the concave-convex-concave process, the driving rod moves from the highest to the lowest, and the drive motor stops. At least one switch identifier is provided, and a switch (not shown in the figure) is also included to control the start of the drive motor. Pressing once drives the drive motor, and the shutdown is controlled by the MCU module. This mechanism can increase manual operation or prevent misoperation. Manual and automatic function, when the drive rod is at the highest position, the rocker arm disengages from the gear set, that is, in the third state, the moving part is manually operated, and the rocker arm is forced to drive the gear set in the reverse direction. For details, please refer to the attached drawings in the specification. Figure 6 At this time, the drive motor and the rocker arm no longer rotate, and the wall-mounted water stopper assembly can be manually hung. In this state, the piston can also be manually controlled individually to open or close the drainage of the drain pipe.

[0040] Furthermore, a shell 91 is provided on the outer periphery of the drain pipe, and the reversing device can be provided in the shell. The shell also includes a button 92, and pressing the button can start the driving motor once.

[0041] In one use, the water stopper assembly includes a piston rod 83 located above the connecting rod, the sealing ring is arranged above the piston rod, and the bottom of the piston rod is sleeved in the connecting rod. This is a simple water stopper assembly, which is a relatively economical style. The other is a bouncing style with a heart-shaped structure. Specifically, the following features are added to the economical style: a spring 84 is provided between the piston rod and the connecting rod, and the spring can drive the piston rod and the connecting rod to separate; a heart-shaped groove 85 is provided on the piston rod, and also includes a connecting piece 86, one end of the connecting piece is hinged to the connecting rod, and the other end of the connecting piece can slide in the heart-shaped groove, so that the heart-shaped groove has two extreme positions, as shown in the attached drawings of the specific specification. Figure 7 、 Figure 8 By pressing the piston, the other end of the connector moves back and forth between the two extreme positions, causing the piston to pop out of the connecting rod or merge, and the drain pipe can be opened or closed. In other words, manual pressure on the piston can also be used to drain water, overcoming the problem of power outage. The drainage device can still be used normally. This structure is similar to the existing heart-shaped groove structure and will not be elaborated here.

[0042] The utility model details: The entire assembly is fixedly installed in bathroom cabinet basins, sinks, bathtubs, and other water containers. It can also be used with smart faucets, and in scenarios such as intelligent water supply and drainage. The water stopper assembly can be simple or push-to-pop; it acts as a water storage and drainage switch. The other end is connected to the automatic reversing device, and the swing arm rotates to cause the sealing ring on the piston to move up and down, thereby controlling the drainage and storage of water. Button: The user inputs a demand signal to control the start-up of the drive motor. It can be a separate remote control or an integrated or split controller combined with peripheral products of the drain.

As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments.
