  • Publication number: 20220195745
    Abstract: An underwater debris suction apparatus includes a power device and a filter device. The power device includes a suction component and a power drive device configured to provide power for the suction component. The underwater debris suction apparatus further includes a collection device, and the upper end of the collection device is provided with an opening. The suction component is at least partially located above the filter device or is entirely located in the space of the filter device. During operation of the suction component, unfiltered pool water enters the filter device through a water inlet channel and flows to the side wall of the filter device, so that the filtered water is discharged from the side wall of the filter device, and the debris that cannot be discharged from the side wall of the filter device falls into the collection device.

  • Publication number: 20210238876
    Abstract: A mechanism for detecting obstacles and mechanically reversing (a direction of) a pool cleaner includes a drive part in non-rotatable connection with a cleaner housing, an arresting assembly connected to the cleaner housing, and a rotary direction-changing assembly rotatably connected to the cleaner housing or the drive part. The arresting assembly cooperates with the rotary direction-changing assembly. The mechanism for detecting obstacles and mechanically reversing (a direction of) a pool cleaner is compact in structure, low in manufacturing cost, and can perform obstacle detection and change a direction of the pool cleaner. With the structure of the rotary direction-changing assembly capable of rotating relative to the cleaner housing, the cleaner, when meeting an obstacle, is allowed to change the traveling direction, thereby resulting in a high working efficiency.

  • Publication number: 20200150679
    Abstract: An obstacle touching detecting device for a swimming pool cleaner includes a main functional portion of the cleaner and a sensor obstacle touching detecting device. The main functional portion of the cleaner includes a cleaner main body, a controller module, and a power-driven actuating device. The controller module and the power-driven actuating device are connected to the cleaner main body. The sensor obstacle touching detecting device includes a trigger unit connected to the cleaner main body and a sensor detecting module electrically connected to the controller module. The controller module is electrically connected to the power-driven actuating device. The trigger unit works collaboratively with the sensor detecting module to trigger the sensor detecting module to generate a detection signal. An automatic detection is performed when the cleaner touches the wall or other obstacles, and the cleaner is controlled to change direction automatically.
