Abstract

本实用新型公开一种尿湿报警器,探头的两端分别接IC集成电路的输入端,IC集成电路的2、3端接电源,抗干扰电容跨接在IC集成电路的1、3端之间,IC集成电路的输出端4接放大电路的输入端,扬声器和指示信号灯接放大电路的输出端,调节电阻串接在扬声器与音频放大电路之间。当尿液碰到探头时,探头间的阻抗发生变化,触发IC集成电路接通放大电路,发出报警音响指示,提醒人们更换尿布。可广泛用于婴儿、病瘫痪者及行动不便人员的尿湿状况报警。

Description

尿湿报警器
本实用新型涉及一种报警器的改进,确切地说是公开一种尿湿报警器,属于电子报警装置技术领域。
现有的尿湿报警器一般采用分离元件,体积比较大,电路比较复杂,工作的可靠性差,影响了尿湿报警的使用功能。
本实用新型提供一种尿湿报警器,采用IC集成电路构成,解决了现有报警器体积大、电路复杂等缺欠。
本实用新型的技术解决方案如下:在尿布的夹层中安放有两根相距一定距离排列的柔软导线构成的探头,由IC集成电路、音频放大电路、扬声器、阻容元件、电源构成报警器,其中探头的两端分别接IC集成电路的输入端,IC集成电路的2、3端接电源,抗干扰电容C跨接在IC集成电路的1、3端之间,IC集成电路的输出端4接音频放大电路的输入端,扬声器和指示信号灯接音频放大电路的输出端,调节电阻串接在扬声器与音频放大电路之间。
本实用新型接通电源时,报警器就处于工作状态,当尿布被尿湿后,探头之间的阻抗度变小,触发IC集成电路中的开关电路,接通音频放大电路,发出报警音响和信号指示,提醒人们更换尿布。
本实用新型的积极效果在于:电路简单,价格低廉,工作性能安全可靠,采用集成电路体积小巧,携带方便,广泛用于婴儿、病瘫痪者及行动不便人员的尿湿情况报警。
图1为本实用新型电路结构原理图。
下面结合附图进一步说明本实用新型:在图1中,IC集成电路选用KD-153N、376-08、CL9300中任意型号的芯片,芯片中包括开关电路、延时电路、频率发生器、变频电路构成,其输出端1、2接探头T的两端,电源E(3V)跨接在IC集成电路2、3端,抗干扰电容C(0.033μf)接在IC的1、3端,IC的输出端4接音频放大电路TG的输入端(基极),扬声器S(8Ω、0.25w)和指示信号灯D(发光二极管)接音频放大电路TG的输出端,调节电阻R串接在扬声器S与音频放大电路TG之间。
