Patent Description:
A baby bouncer, also known as baby swing, soothes the baby through fixed, gentle, and regular bounces. After a baby is born, the bouncing stimulus it received in the womb disappears, which can make the baby uneasy. Therefore, the baby needs to be bounced again to be satisfied. Existing baby bouncers are divided into manual and automatic baby bouncers, both of which can only swing back and forth in a single direction. The unidirectional swing cannot offer a comfortable sitting or lying experience for babies, and cannot achieve an ideal sleep inducing function. <CIT> discloses an infant care apparatus. The infant care apparatus includes a base; a drive mechanism disposed on the base; a controller electronically coupled to the drive mechanism; and a support device coupled to the drive mechanism. The support device is configured to be moved in both a horizontal and vertical direction relative to the base by the drive mechanism. The drive mechanism is controlled by the controller to move the support device in a plurality of motion profiles relative to the base. <CIT> discloses a robot bouncer. The robot bouncer comprises a main body, an elevating shaft, a seat, a Z-axis motion module, an X-axis motion module, a Y-axis motion module, and a control unit. In the main body, an open space is prepared on the top thereof. In the elevating shaft, a part thereof is projected from the top of the main body through the open space of the main body. The seat is connected to the upper end of the elevating shaft by the medium of a connection bar. The Z-axis motion module transfers the Z-axis motion downward and upward.

The present disclosure provides an electric baby bouncer, which mainly aims to solve the problem of existing baby bouncers.
