Description

Baby's electric cradle

Technical field the utility model relates to a kind of baby's electric cradle.

The present most of baby's electric cradles of background technology adopt 220 volts of alternating currents to make motor power.Because each family has only a child now, although electric cradle is very safe in the use, the heads of a family are for the fear to dangerous voltage, still feel very to worry for the electric cradle that uses 220 volts alternating current, as the saying goes and be not afraid of 10,000, just be afraid of contingency, will bring on a disaster to family just in case electric leakage occurs.And when using battery that 36 volts following safe dc sources are provided, because motor needs frequent commutation, power consumption is big, needs frequent charge, uses inconvenience.So the heads of a family often select manual shaking table when choosing.

Summary of the invention is to be solved in the utility model to be to use baby's electric cradle power consumption of low-voltage dc power supply bigger, thereby charges frequent problem.

A kind of baby's electric cradle of the utility model, comprise a body, bedstead, drive unit and agitating device, the bed body is hinged on bedstead by the connecting rod at two ends, drive unit is fixed on the support of bedstead below, is made up of motor, speed change gear and power transmission shaft, and power transmission shaft is vertically fixed on a body below by support, described agitating device is made up of reel, pull rope, reel is gone up on the power transmission shaft by switching mechanism is fixing, and pull rope one end is fixed on the reel, and the other end is fixed on the body; Described switching mechanism is made up of slide bar, sliding pin and pulling block, has axial hole on the power transmission shaft, and slide bar is arranged in the axial hole of power transmission shaft, is fixed with sliding pin and pulling block on the slide bar sidewall, has the axial slide that cooperates with sliding pin, pulling block on the power transmission shaft; The block that cooperates with pulling block is arranged on the reel, the power transmission shaft outside is provided with axle sleeve, and axle sleeve is fixed on the support, is provided with the circumferential track that cooperates with sliding pin in the axle sleeve, described track is made up of upper and lower two semi circular paths, has twilight orbit to link to each other between the two ends of two tracks.When driven by motor power transmission shaft during around the rotation of direction, power transmission shaft drives reel rotation and coiling draught line by pulling block, drives a bed body and swings to an end; When power transmission shaft rotation half cycle, sliding pin enters another track by a track, promotes to move or move down on slide bar and the pulling block, and the block on pulling block and the reel is broken away from, this moment, the bed body was moving to backswing under the effect of deadweight, carried out reverse unwrapping wire by pull rope drive reel and rotated; When power transmission shaft rotated to other half cycle, sliding pin entered another track again by a track, promoted to move or to move down on slide bar and the pulling block, and pulling block contact with block on the reel, drove reel rotation and coiling draught line, and a drive body is swung to an end; Continuous so repeatedly, and motor is in the rotation of same direction always, need not commutation, power consumption is little, thereby when providing safe low voltage and direct current to make power supply with battery, each service time is long, the frequent charge phenomenon can not occur.

Described shaking table is provided with the shaking table automatic control circuit that vagitus causes, and this control circuit is made up of sound pick-up, amplifying circuit, timing circuit, on-off circuit and relay, and a pair of normally opened contact of relay is connected on the motor power circuit.When the baby cries and screams when sounding, sound pick-up sends the signal of telecommunication through amplifying circuit and timing circuit, makes the on-off circuit action connect motor power, and shaking table begins to wave automatically, till the predefined time.

Also be provided with baby's suggestion device of pissing on the described shaking table, this device is formed by the wet probe of urine, amplifying circuit with by the pronunciation circuit that oscillating circuit, power amplifier, loudspeaker are formed, after the baby is wet with diaper urine, the wet probe of urine that is located on the diaper sends the signal of telecommunication, after amplifying circuit amplifies, send Tip Sound by pronunciation circuit, give baby's diaper-exchanging to remind the head of a family.

When the utility model adopts switching mechanism that shaking table is swung, motor need not commutate, power consumption is little, being fit to provides 12 volts of safe low voltage and direct currents with battery, use as safe as a house, automatically shaking table when the baby cries and screams in addition, and be provided with the wet suggestion device of urine, can alleviate the workload of head of a family's baby-sit.
