Abstract

本实用新型提供一种家用有害气体、火灾报警器，涉及家用有害气体、火灾报警器，其要解决的技术问题是：由报警盒、电源插头、变压器、气敏传感器及其电路、喇叭组成，把家用有害气体火灾报警器插于易发生灾害的地方的电源插座上，当有害气体或起火烟雾，接触到气敏传感器(3)时，其阻值降低，使时基电路的复位端4脚电压上升，当电压达到时基电路电源电压的1/3时，输出端3脚输出高电频，驱动喇叭发出报警声，就能及时排除故障，保障生命财产安全。

Description

家用有害气体、火灾报警器
技术领域
本实用新型涉及一种家用有害气体、火灾报警器。
背景技术
目前公知的家庭中天然气、煤气常有泄漏及火灾时有发生，而目前市场上没有供家庭用的有害气体、火灾报警器。
发明内容
为了克服上述不足，本实用新型提供一种家用有害气体、火灾报警器，就能达到家庭中天然气、煤气泄漏产生有害气体或电器起火时及时报警的目的。
本实用新型要解决的技术问题其技术方案是：其电路所示，时基集成块及周围元件组成的触发和报警电路将气电转换，12V的电源对气敏元件加热灯丝进行稳压，就能将报警器稳定工作在120V～260范围，当电路工作时，由时基电路组成的自激多谐振荡器利用它的复位端进行触发，当气敏元件接触到有害气体和火灾烟雾时，其阻值降低，使时基电路复位端4脚电压上升，当电压达到时基电路电源电压的1/3时，输出端3脚输出高电频，驱动喇叭发出报警声。其结构是报警盒底面设有插头，通过电源开关K与装在报警盒内的变压器初级连接，报警盒内装有电路部分，盒的上端的周围开有条形窗口，顶上面开有通气孔，通气孔内安装有气敏传感器，条形窗口下端的中部开有条形窗孔，条形窗孔内安装有喇叭，下端的侧面装有电源开关和指示灯。
本实用新型的有益效果是：家中装上家用有害气体、火灾报警器，如有天燃气或煤气泄漏和电器起火或其它起火，都能及时报警，起到及时消除灾害的发生，保障生命财产安全。
附图说明：
下面结合附图对本实用新型作进一步说明。
图1为家用有害气体、火灾报警器全景示意图。
图2为家用有害气体、火灾报警器电原理图。
图中：1、电源插头，2、变压器，3、气敏传感器，4、时基集成块，5、喇叭，6、指示灯，7、报警盒，8、通气孔，9、条形窗口，10、报警盒中部，11、窗孔，12、电路部份，K，开关。
具体实施方式：
报警盒(7)设有电源插头(1)，电源通过开关(K)与装在报警盒(7)内的变压器(2)初级连接，盒内装有电路部分(12)，盒的上端周围开有条形窗口(9)盒顶上开有通气孔(8)，通气孔内装有气敏传感器(3)，条形窗口下端的报警盒中部(10)开有条形窗孔(11)，窗孔内装有喇叭(5)报警盒下部的侧面装有电源开关K和指示灯(6)。
把家用有害气体、火灾报警器，插于易发生灾害地方的电源插座上，如有有害气体泄漏，或起火烟雾接触到气敏传感器时，其阻值降低，使时基电路的复位端4脚电压上升，当电压达到时基电路电源电压的1/3时，输出端3脚输出高电频，驱动喇叭发出报警声，就能及时消除故障，保障人生财产安全。

Claims (1)
