Abstract

The utility model discloses an electrically operated sound-controlled child's hammock, which is composed of a folding hammock, a folding bracket, a round-topped mosquito net, an automatic deviation-rectifying device, a stabilized voltage supply, a sound-controlled device, a delayer, an electronic switch, an electromagnet, a temperature sensor, a wet sensor, a music block, etc. The utility model has the functions of automatically swinging, delaying automatic stop, swinging again when the child cries, music hypnogenesis, bed-wetting alarm, and calling when the quilt is kicked off. The utility model is an adult bed. The electronic device can also be used for the functions of household sound control, timing, alarm, a doorbell, etc. The utility model has the characteristics of low power consumption of hanging and swinging, noiselessness, no vibration, no damage to the flooring (the commonly used carpet, floor glue and paint in cities and towns), simple electronic circuits, multiple functions, low cost and favorable popularization.

Description

Electrically operated sound-controlled child's hammock

The utility model belongs to a kind of improvement of basket cot.

Existing basket cot, infant period for hypnosis, must shake on the ground or spur, vibration and noise are all very big, very easily roll damage carpet, floor glue or floor paint again, especially need manpower to shake and guard.

The purpose of this utility model is to provide a kind of main body bed use age long, and the friction noiselessness does not damage pavement, the electronic acoustic control children hammock that the function that does not need the people to guard is more.

For this purpose, the present invention adopts deployable folding bed for adult's usefulness, two ends borrow chain to hang on folding bedstead, outer cover garden top mosquito net, bed dispose the electronic installation of being made up of electronic controller, the wet temperature detector of microphone sense, music-integrating block down, and control electromagnet traction Children waves automatically, the time-delay automatic stop, wet the bed and report to the police, play and called out, crying disturbs by making noise shakes again, constantly sends the hypnosis music when shaking.

It is as follows now to press description of drawings.

Fig. 1, Fig. 2 are the agent structures of taking off mosquito net.(1) be that deployable 1000 * 580mm is the Children of single bed.Available steel wire of bed surface (6) or nylon yarn woven cloth, bed two ends mat chains (5) are hung on bedstead vertical rod (13), U type frame (2), the supported folding steel pipe bedstead that (16), locking leaf collude (15), connect supporting mass (14) in flakes, ornament ball (4) is formed.Top, garden tester (3) inserts in ornament ball (4) central blind hole.Remove the locking leaf and collude (15) downwards by means of (16) can be with the folding gathering of frame in flakes.Electromagnet (8) is fastened on and connects on the supporting mass (14).Magnet tractive force borrows backguy (12) to be delivered on transmission Xiao (11).Influence the magnet air gap partially in order to overcome to sleep after the baby stands up, the present invention has set up the automatic aligning deviation correcting device.See Fig. 3, tractive force pulling correction fork (19), and borrow elastic-friction sheet (18), frictional force adjustment screw (20) pulling Children end frame (17) waves.When standing up suddenly, the baby sleeps when causing bedstead to tilt partially, the inertia energy that utilizes pendulum (21) in reciprocally swinging, to store, the frictional resistance that overcomes elastic-friction sheet (18) is adjusted angle automatically with bed end frame (17), constant to keep fork (19) perpendicularity, thereby guarantee that the magnet air gap is constant, promptly the amplitude of oscillation and tractive force are constant.Air gap adjustment screw (22) is adjusted air gap and is used when confessing factory and appraising and deciding the power and the amplitude of oscillation.

Fig. 4 is an electrical schematic diagram.Utilize vagitus after the energising, father and mother's voice becomes the signal of telecommunication by electret microphone (9), borrows BG ₂, BG ₃Amplify back output positive pulse and trigger D ₃The turn-off SCR conducting makes relay J work, normally opened contact J-2 closure, and output 36V direct current after the bidirectional triode thyristor D4 conducting D5 rectification, electromagnet DT adhesive, hammock is subjected to the pulling force beat.When hammock collision block contact miniature slide switch K, K controls the utmost point with D4 and disconnects, and the D4 alternating current is crossed zero to cut-off, and the electromagnet outage discharges, and hammock is borrowed the deadweight return, and K leaves the energising that resets behind the collision block, and electromagnet is adhesive again, and the hammock makeup energy is constantly back and forth waved.Music block IC is open-minded by the J-1 closure, sends lullaby.

Meanwhile, R10 charges to C5 in the delayer, about 20 minutes when reaching the BG4 peak dot, unijunction transistor BG4 conducting, C5 discharges rapidly, equals to carry a very big negative pulse to D3, turn-off SCR ends, J discharges, and J-1 normally opened contact and J-2 disconnect, and electromagnet and hypnosis piece quit work.The R10 outage, C5 drains.Data see Table 1, when the baby is noisy, repeats said process again by electret microphone (9) and move.Temperature sensor R12, humidity sensor SK(Fig. 1,10, also can be split up into two kinds) work all the time.After the baby wets the bed or raises quilt, the SK that be placed on baby front and the R12 of pad under baby's stern changes numerical value and makes the IC(can be with two of different acoustic) trigger open-minded, borrow shared loudspeaker Y to give a warning, the household is in time changed urinate pad or build quilt, prevent that the baby is caught cold by stain.

It is very simple that SK makes, and the long 200mm two ends that will peel off insulated part with two leads separate with cotton grew sheet one deck, and overseam is placed on well under the diaper.

This device is available powered battery also, but uneconomical, so this book does not describe in detail.
