Description

Intelligent cradle

The utility model relates to a kind of can waving automatically, and the electric baby bouncing cradle of have regularly, record, wet the bed caution, feeding bottle constant temperature function.

Shaking table is that the infant fosters a kind of bed accessory practical in the work, especially summer scorching temperature use shaking table season, can directly reduce baby and mother's (or nurse) Body contact, thereby avoid bacterial infection and the skin disease that causes, as eczema, prickly heat etc.According to investigations, shaking table in the market (wooden or steel) all adopts original machinery to wave structure, and as power, actuation time is short with people's externally applied forces, and rocking tendency tool randomness is with low content of technology, no automation composition.

The purpose of this utility model provides a kind of intelligent cradle, and it can not only wave automatically, and have regularly wave, speech recording and reproducing, bed-wetting caution, feeding bottle constant temperature function.

The purpose of this utility model is achieved in that installs two permanent magnets in cradle bottom, correspondingly with it in frame bottom two electromagnet are set, and forming first pair of induced magnet respectively provides induced signal, and forming second pair of work done magnet simultaneously provides power.According to electromagnetic induction principle, when external force is tried hard to recommend when shaking basket as first motion, the permanent magnet in the first pair of induced magnet skims over from induced electricity magnet top, and induced electricity magnet produces electric current, after circuit is accepted induced signal, makes the acting electromagnet get the electric magnetic field of setting up.The permanent magnet of this magnetic field and correspondence is relative to be same polarity, therefore produce to repel thrust, and the air drag when this thrust has overcome the cradle swing and the frictional force of bearing, formation is waved.Cradle moves to after top dead center, and toward swivel motion, the permanent magnet of first centering skims over from induced electricity magnet top once more, repeats above-mentioned induction by potential energy---and the acting process and so forth, forms the fixing amplitude of oscillation.Be the resistance of reducing friction, four jiaos of cradle bottoms and a top of the trellis are all installed bearing for four jiaos, are axially connected by rocking arm formation between cradle and the support, to guarantee merrily and lightheartedly waving of cradle.Adopt electronic timing circuit control to wave the time simultaneously, adopt low-voltage, low current control bed-wetting acousto-optic warning, adopt the anti-outage of solid audio record circuit to carry out the segmentation recording, adopt PTC constant temperature calandria to keep feeding bottle constant temperature, wave automatically and have an intelligentized purpose thereby reach.

Owing to adopt such scheme, make cradle realize waving automatically, and have intelligent function, simple in structure, components and parts are general easily to be purchased, and each functional circuit is relatively independent, whether is provided with all not influence automatically to wave.

Below in conjunction with drawings and Examples the utility model is further specified.
