Abstract

一种用于小孩睡觉被被踢开温度下降而报警的 温控防冻报警器，由外壳以及安在外壳里的热敏电阻 或带触点的微型水银温度计、可调电阻、集成块、蜂鸣 器、直流电源和开关组成。其特点是体积小，结构简 单，造价低、性能可靠。

Description

本实用新型属用于保健的电子产品。
从所周知，小孩睡觉时，经常用脚把被踢开，而同房不同床睡觉或同床已熟睡的大人往往不知道，造成小孩受凉生病。
本实用新型的目的在于提供一种可放在小孩的被窝里，当小孩把被踢开，温度下降后即发出声响使大人发觉即把被重新盖上的温控防冻报警器。
本实用新型是采用热敏电阻或带触点的微型水银温度计、蜂鸣器、集成块和直流电源组成电路，利用温度变化时，热敏电阻阻值也发生变化，或带触点的微型水银温度计水银柱也发生变化的原理，使蜂鸣器在温度低时，发出声响报警的方式来达到目的的。
本实用新型的特点是体积小、结构简单、造价低、性能可靠。
下面结合附图来说明实施例：
附图为本报警器电路图。
参照附图，本报警器由外壳A以及安在外壳里的热敏电阻或带触点的微型水银温度计t，可调电阻R、集成块IC1、IC2、蜂鸣器HTD、直流电源V和开关HK组成，电源V输出线路安有开关HK，可调电阻R的一端、热敏电阻或带触点的微型水银温度计的一端与集成块IC1信息输入端VI1连接，可调电阻R另一端与集成块IC1、IC2的电源输入端VCC1、VCC2接电源正极＋。热敏电阻t另一端与集成块IC1电源输入端GND接电源负极－，集成块IC1输出端V01接集成块IC2输入端VI2，集成块IC2输入端VO2接蜂鸣器HTD，外壳A形状可象某动、植物或吉祥物，不限定。
