Abstract
An automatic feeding device includes an accommodating container, a transmission channel, a valve unit, a sensor and an ejection unit. The transmission channel is disposed on bottom of the accommodating container. The transmission channel has an inlet portion, a central portion and an outlet portion. The central portion is between the inlet portion and the outlet portion. The valve unit is disposed on the bottom of the accommodating container and adjacent to the inlet portion. The valve unit is switchable to allow feed inside the accommodating container for passing the inlet portion and entering the transmission channel. The sensor is disposed on the inlet portion and detects whether the feed passes the inlet portion, and further outputs a control command to switch modes of the valve unit. The ejection unit is disposed on the central portion and used to push the feed inside the transmission channel toward the outlet portion.
