Open Close Mechanism Ref:-Pet feeder mechanism A pet feeder mechanism typically consists of a container for storing pet food, a dispenser or conveyor system to release the food, and a control mechanism to regulate feeding times. Some feeders use timers or electronic programming to dispense specific amounts of food at scheduled intervals, ensuring regular feeding for pets. Gravity-based feeders rely on the natural flow of food as the container empties, while more advanced models may incorporate features like portion control, smartphone connectivity, and even cameras to monitor and interact with pets during feeding.
