Description

Frostbite-preventing health toy for baby

The utility model relates to the antifreeze health toys of a kind of baby that antifreeze health care combines with the ordinary electronic toy, is used for baby and endures cold night and report to the police and can be used as ordinary electronic singing toy, decorative toy.

The reason that baby is caused a disease is very common kicks open the head of a quilt when being nighttime sleep so that endures cold, cause flu, heating, cough, asthma, poor appetite, symptom of diarrhea, young mother likes again to sleep night very much, be difficult for looking after the defective that baby constantly will play the head of a quilt, usually solution is to make baby and father and mother with sleeping, but the easily mutual communicate illness of the not enough health of the method, and difficulty prevents that baby's health from shifting out quilt and endure cold, additive method is can not fine solution antifreeze, in the present circumstance, still lack a kind of baby that effectively prevents simple and easy and science and play the method that the head of a quilt is easily endured cold night.

The purpose of this utility model is to use modern electronic technology, and the electronics of controlling toy with baby's body temperature synthesizes song, and the mother during song is waken and slept soundly thus solves baby and plays the head of a quilt to topic; By day, this toy still can be made the toy of decorative toy and electronics synthetic video for baby's object for appreciation.

Scheme of the present utility model is the body temperature that the thermistor that is placed on baby front top detects baby; Baby's variations in temperature on one's body is fed to the sound light alarming circuit of forming by transistor, IC integrated electronic sound synthesizer, light emitting diode, loudspeaker, when baby because of playing within the head of a quilt endured cold one minute, this circuit promptly sends graceful musical sound and wakes mother in sleeping soundly; When being used as decorative toy or general toy, as long as by a change-over switch, and at the toy privileged site, adorn a push switch as the nose areas of the little black bear of toy, send graceful song once control IC integrated electronic sound synthesizer by this switch by loudspeaker, and make the eyes that light emitting diode is housed glittering.

The utility model embodiment is described in detail in conjunction with the accompanying drawings.

Fig. 1 is the antifreeze health toys outline drawing of baby,

Fig. 2 is the antifreeze health toys electronic circuit of a baby schematic diagram.

By Fig. 1, shown in Figure 2, be equipped with by transistor T1～T4 in interior, IC integrated electronic sound synthesizer, light emitting diode D3～D4, the sound light alarming circuit that loudspeaker is formed, a thermistor R2 who detects baby's body temperature is connected with transistor T1 base stage by plugs and sockets, be connected with IC integrated electronic sound synthesizer CW9300 by transistor T2 emitter stage, one end of electro-acoustic synthesizer and the T3 of transistor, the T4 base stage is connected, between the anode of T3 colelctor electrode and power supply, be connected to a loudspeaker, the collector output of T4 is connected to two light emitting diode D3, D4, the control end of electro-acoustic synthesizer connects a push switch K1 and is connected with power supply E by change-over switch K2.Operation principle of the present utility model is as follows: when baby's body temperature just often, thermistor R2 resistance is little, at this moment, transistor T1 conducting, T2 ends, and in advance change-over switch K2 is on 2 positions, at this moment, the electro-acoustic synthesizer is not worked, do not have sound, after baby kicked open the head of a quilt, health was caught a cold, the thermistor R2 resistance of placing top, baby front this moment increases, T1 ends, and the T2 conducting makes the work of electro-acoustic synthesizer, make T3, the T4 conducting, thereby make loudspeaker send graceful song and wake the middle mother that sleep soundly, the toy eyes are also glittering, wait baby built after; baby one is warm, song and luminously also thereupon disappear.Thermistor can be removed by day; Change-over switch K2 is positioned over 1 position, as long as push on the toy this moment (for example nose areas) K switch 1 on the privileged sites make the electro-acoustic synthesizer directly and power supply E join, then drive transistor T3, T4 loudspeaker is sung, the toy eyes that light emitting diode D3, D4 are housed are also glittering.

The utility model is that the warning device by the health care of electronic toy and temp. controlled frost-proof combines, and not only can be used as baby's antifreeze health-promoting apparatus but also can be used as the toy on daytime, and toy can be made for example little black bear of various shapes, lesser panda etc.

Claims (1)

1, a kind of antifreeze health toys of being made up of housing, temperature sensor, sound light alarming circuit of baby is characterized in that: be equipped with in the toys shell by transistor T ₁～T ₄IC integrated electronic sound synthesizer, light emitting diode D ₃, D ₄And the sound light alarming circuit of loudspeaker composition; A thermistor R who detects baby's body temperature ₂An end and transistor T ₁Base stage connects, and the control end of electro-acoustic synthesizer connects a push switch K ₁By change-over switch K ₂E is connected with power supply.
