Abstract
The utility model discloses an alarm for preventing a child from kicking a quilt in sleep. In the utility model, the resistors R < 1 >, R < 2 > of the input circuit of the alarm for preventing a child from kicking a quilt in sleep and adjustable resistance W are connected between power supply voltage and earth wire in series; the R < 2 > is a temperature measuring element, and the connecting point between the R < 1 > and the R < 2 > is connected with the input terminal of a trigger circuit IC < 1 >; the output terminal of the trigger circuit IC < 1 > is connected with a musical circuit IC < 2 > through a diode D < 2 >; the R < 3 > of a delay circuit and the C < 1 > of the delay circuit are connected between the power supply voltage and the earth wire in series; the connecting point between the R < 3 > and the C < 1 > is connected with one foot of the IC < 1 > and is connected with earth through a switch K. When the quilt is kicked, the utility model can sound alarm sound in time for remind families well covering the quilt for the child. The utility model has the advantages of simple structure, low cost, and easy enforcement.
Description
The utility model relate to a kind of temperature control alarm, especially children sleeping pedal by alarm.
Children usually can be pedaled quilt in bed and hold night, and children's household also is in sleep state, builds as untimely, and it is sick that children can suffer from cold, the infringement children's health.
The purpose of this utility model provides a kind of children sleeping Quilt-kick-off alarm.It can children pedal by the time send chimes of doom, remind the household in time to build quilt for children.
The technical solution of the utility model comprises input circuit, trigger circuit, music circuit, delay circuit and light display circuit.The resistance R of input circuit
1, R
2And adjustable resistance W is serially connected between supply voltage and the ground wire R
2Be temperature element.R
1And R
2Between contact connect a trigger circuit IC
1Input end 2 pin, IC
1Output terminal 4 pin are by a diode D
2Connect a music circuit IC
2The B pin, loudspeaker Y is serially connected in supply voltage and IC
2The C pin between.The R of delay circuit
2And C
1Be serially connected between supply voltage and the ground wire R
3And C
1Between contact and IC
11 pin join and by a K switch ground connection.The light emitting diode D of light display circuit
1With R
4Be serially connected between supply voltage and the ground wire.
During use, with temperature element R
2Be placed in children's the quilt.When quilt is pedaled out, R
2Temperature reduce, resistance increases, IC
12 pin current potentials rise IC
13 pin current potential step-downs, IC
14 pin be noble potential, this noble potential is by diode D
2Make music circuit work, promote loudspeaker Y and send the sound, realize the purpose of reporting to the police.
When the utility model is pedaled out quilt children, can in time send chimes of doom, remind the household in time for children build quilt, make the household needn't because of worry children pedal by, and stand up to watch the influence sleep again and again.It is simple in structure, and cost is low, easily implements.
Elaborate below in conjunction with drawings and Examples.
Accompanying drawing is the utility model circuit diagram.
In the embodiment shown in the figures, R
