发明名称 Children's learning device with countdown timer
摘要 A child's learning device includes a housing, a countdown timer and a driving mechanism. The housing includes a main body and an appendage attached to the main body, the appendage pivoting between a first orientation and a second orientation. The countdown timer includes a control mechanism for designating one of a plurality of designated time periods. The driving mechanism is connected between the countdown timer and the appendage. The driving mechanism and countdown timer are configured such that manually pivoting the appendage from the first orientation to the second orientation sets the countdown timer for the designated time period, and the appendage is driven back from the second orientation to the first orientation over the course of the designated time period by mechanical force provided by countdown timer to the driving mechanism.
