  • Patent number: 11761225
    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.
