Abstract

The utility model relates to a cold-proof signal, mainly comprising a direct-current power supply, a temperature-sensitive element, an adjustable resistance, a monostable circuit, a language integrated sheet and a sounder. When a child sleeps outside a quilt, the temperature-sensitive element attached on the child's clothes is sensitive to the low temperature outside the quilt, the input electric potential of the monostable circuit is reduced, the output electric potential of the monostable circuit is positioned at a high level, the language integrated sheet and the sounder are started by the high level, and therefore, the cold-proof signal achieves the goal that the cold-proof signal reminds adult to care for the child in time. The cold-proof signal has simple structure, good performance and reliable use.

Description

Cold-proof signal when sleep

The utility model belongs to electronic technology field, relates to a kind of individual and household supplies.

In daily life, young father and mother are because of tired some the cooking methods that lack again simultaneously that work by day, the time that tends to make child to sleep outside quilt at night is longer, the phenomenon that child gives rise to diseases because of suffering from cold is a lot, influences the healthy of children, hinders study.

The purpose of this utility model is: when child sleeps in the quilt outside, can in time remind the adult to correlate.

In order to achieve the above object, the technical solution of the utility model is achieved in that passes through temperature-sensing element (device), the temperature of responsive quilt inside and outside, when child sleeps in the quilt outside, it is responsive to low temperature and export control signal and give articulatory system and make it pronunciation to be attached to sensitive element on child's clothes, thereby reaches the purpose that the prompting adult correlates child.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Accompanying drawing is the circuit theory diagrams of the utility model embodiment: monostable circuit 1, language set in blocks 2 and acoustical generator 3 constitute articulatory systems, with thermistor Rt as temperature-sensing element (device), R ₁Be adjustable resistance, thermistor Rt and adjustable resistance R ₁Be connected on the two ends of direct supply after the series connection, from thermistor Rt and adjustable resistance R ₁Between draw the control signal of a signal as monostable circuit 1, the output of monostable circuit 1 is as the input control signal of language set in blocks 2, the output signal of language set in blocks 2 is connected on the acoustical generator 3, when thermistor Rt sensitivity arrives the low temperature of quilt outside, the variation of thermistor Rt resistance causes the variation of A point current potential, this low level is controlled its output high level as the control signal of monostable circuit 1, this high level makes language set 2 work in blocks and then makes acoustical generator 3 sounding, thereby reaches the purpose of reminding the adult to correlate child.After building quilt to child, the temperature of thermistor Rt sensitivity in the quilt, the current potential that the variation of thermistor Rt resistance can make A order raises, this noble potential makes its output low level as the control signal of monostable circuit 1, this low level makes language set in blocks 2 enter off working state, and acoustical generator 3 stops sounding.By changing adjustable resistance R ₁Resistance, can make the sleep exempt to catch a cold pager can reliably working in any season.

Claims

1, the pager of catching a cold is exempted from a kind of sleep, it is characterized in that: it is mainly by Dc low voltage power supply, temperature thermal sensing element Rt, adjustable resistance R ₁Constitute with articulatory system.

2, the pager of catching a cold is exempted from sleep according to claim 1, it is characterized in that, articulatory system is made of monostable circuit 1, language set in blocks 2 and acoustical generator 3, temperature-sensing element (device) Rt and adjustable resistance R ₁Be connected on the direct supply two ends after the series connection, from temperature-sensing element (device) Rt and adjustable resistance R ₁Between draw the control signal of a signal as monostable circuit 1, with the output of monostable circuit 1 input, with the output of language set in blocks 2 input as acoustical generator 3 as language set in blocks 2.
