Abstract
The utility model relates to a baby quilt-kicking alarm, comprising a sound source synthetic integrated circuit and a photosensitive control circuit. When the baby kicks away the quit, the alarm can automatically send out musical sound to alarm. The utility model has the characteristics of specially simple structure and circuit, small volume, light weight, low cost, easy and convenient installment and use, stable and reliable performance and non-adverse effect on human body. The utility model is provided with a shifting switch for strong and weak light, so that the alarm can be normally used during daytime and at night.
Description
Technical field
The utility model relates to a kind of alarm, especially a kind of baby's quilt kicking alarm.
Background technology
During infant enters deep sleep, can often kick open quilt, in the season in winter, spring, the as easy as rolling off a log baby of making catches a cold and produces other disease.In order to address this problem,,, also can't be used so far owing to the jejune reason of technology though people have designed various warning devices.
Summary of the invention
The problem of playing quilt when solving infant enters deep sleep, the utility model provides a kind of baby's quilt kicking alarm, this alarm is not only simple in structure, and can be effectively the baby play by the time send warning.
The technical scheme that its technical matters that solves the utility model adopts is: this baby's quilt kicking alarm, comprise housing, power switch, the strong and weak Gear-shift switch of light, photoresistance R and sender, be characterized in that it is provided with synthetic integrated circuit of sound source and photosensitive control circuit, the synthetic integrated circuit of described sound source adopts the synthetic integrated circuit of common sound source, circuit connecting mode is: power supply just, negative connection termination music-integrating block LM-5 just, negative pole, loudspeaker SP is connected with positive pole and the power output contact of music-integrating block LM-5, capacitor C is connected with the two oscillatory circuit contacts of music-integrating block LM-5, the input end of photosensitive control circuit is connected with the make and break contact b of music-integrating block LM-5, and the output terminal of photosensitive control circuit is connected with the negative pole a of music-integrating block LM-5.When alarm snapped onto a smooth position height of baby's health, socks covered alarm, and the baby is in normal sleep state, and alarm is sounding not; When the baby kicks open quilt, alarm since photoresistance R conducting send chimes of doom, thereby in time remind the adult to build quilt to the baby.
The beneficial effects of the utility model are:
1, structure and circuit are simple especially, and volume is little, and be in light weight, and cost is low.
2, stable and reliable working performance.
3, safety does not have ill-effect to human body.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a shape assumption diagram of the present utility model.
Fig. 2 is a circuit diagram of the present utility model.
Embodiment
See that from Fig. 1 this baby's quilt kicking alarm can be installed in the little square casing (1), housing (1) surface is provided with power switch (2), the strong and weak Gear-shift switch (3) of light, photoresistance R (5), sender (6) and fibula (4).
From Fig. 2, see, baby's quilt kicking alarm comprises synthetic integrated circuit of sound source and photosensitive control circuit, the positive and negative electrode of the positive and negative connection termination music-integrating block LM-5 of the synthetic ic power of sound source, loudspeaker SP is connected with positive pole and the power output contact of music-integrating block LM-5, capacitor C is connected with the two oscillatory circuit contacts of music-integrating block LM-5, and photosensitive control circuit is by photoresistance R, triode Q and the strong and weak Gear-shift switch K of light
1Form, photoresistance R, triode Q connect, and meet the make and break contact b of music-integrating block LM-5 behind the end of photoresistance R and the collector series connection of triode Q, and the emitter of triode Q is connected with the negative pole a of music-integrating block LM-5.
The principle of work of alarm: referring to Fig. 2, when working by day, the energized K switch, and with the strong and weak Gear-shift switch K of light
1Push K
1-1The position, the baby normally in bed because quilt covered alarm, not conducting of photoresistance R, loudspeaker SP is sounding not, the baby kicks open by the period of the day from 11 p.m. to 1 a.m because photoresistance R conducting, loudspeaker SP sends musical sound; When working at night, with the strong and weak Gear-shift switch K of light
1Push K
1-2The position, the baby normally in bed, because quilt has covered alarm, not conducting of photoresistance R, loudspeaker SP is sounding not, and the baby kicks open by the period of the day from 11 p.m. to 1 a.m, and photoresistance R receives the low light level and is in half conducting state, for the base stage of triode Q provides operating voltage to force triode Q conducting, loudspeaker SP sends musical sound.
Claims (2)
1. baby's quilt kicking alarm comprises housing (1), power switch K (2), the strong and weak Gear-shift switch K of light
