Abstract
The utility model relates to an alarm for freezing prevention for a sleeping baby, which is composed of a soft coating layer, a housing, power supply V, a resistor R< 1 >, a photoresistor R< 2 >, an integrated signal sheet IC, capacitance, an audion, an acoustic horn, and a switch, wherein, the power supply V, the resistor R< 1 >, the photoresistor R< 2 >, the integrated signal sheet IC, the capacitance, the audion, the acoustic horn, and the switch are arranged in the housing or on the housing. When the baby kick a quilt through feet, the alarm sounds, and an adult who hears sound well covers the quilt again for freezing prevention for the baby in case of illness. The utility model has the advantages of simple structure, small size, low cost, and reliable performance.
Description
The utility model relates to a kind of health care electronic product.
The infant kicks open quilt through pin commonly used in bed, and has sexual intercourse different bed sleeps or the adults that slept soundly with bed often do not know that it is sick to cause child to endure cold.
The purpose of this utility model is to provide in a kind of child's of being placed on the quilt, just sends the antifreeze alarm of infantal sleeping of sound when child is kicked open quilt.
The utility model is to adopt integrated signal sheet, on signal sheet input circuit, be equipped with photoresistance, be placed in the quilt, lose the light time at this alarm, not conducting of photoresistance, the signal sheet can not get electric energy, and signal is not exported, when quilt is kicked open, the photoresistance conducting, the signal sheet obtains electric energy, signal output, send just that the mode of sound achieves the goal.
Characteristics of the present utility model are simple in structure, and volume is little, cost is low, dependable performance.
Below in conjunction with accompanying drawing embodiment is described:
Accompanying drawing is this alarm circuit diagram.
With reference to accompanying drawing, this alarm is made up of Soft Roll layer 2, housing 1 and the power supply V, resistance R 1, photoresistance R2, integrated signal sheet IC, capacitor C, triode BG, DI and the K switch that are positioned in the housing or on the housing, power supply V joins with integrated signal sheet IC input end after connecing K switch, be connected to resistance R 1 and photoresistance R2 on the anodal circuit of power supply V, integrated signal sheet IC output terminal is serially connected with triode BG and DL, and transistor base b and collector C connect capacitor C.
