Problems solved by technology

It has a toxic effect on the tissue cells of the whole body, especially the cerebral cortex. Therefore, once a gas leak occurs, it may cause extremely serious consequences. Most of the existing gas alarms on the market use loudspeaker alarms, and their alarm sounds are sharp. If there is a baby or an old man in the family, it will cause great stimulation, and the existing alarm only has a simple alarm function, and its utilization rate is low

Abstract

The invention discloses a safety alert indicator light. The indicator light includes an alternative current-direct current conversion circuit, a detection circuit, an oscillator circuit and an indicator light circuit; the alternative current-direct current conversion circuit is connected to the detection circuit, the oscillator circuit and the indicator light circuit; the detection circuit is connected to the oscillator circuit; and the oscillator circuit is connected to the indicator light circuit. The indicator light adopts an anti-interference power supply to power up and uses an LED lamp as a light source; improvement can be made for existing gas alarms by combining a gas sensor and a triode; and through the combination of gas detection and a lighting lamp, the lamp can be used as lighting under a normal situation and can flicker and shine when an alarm is triggered, so that safety warning effects can be well achieved.

Description

technical field [0001] The invention relates to the field of security alarm technology, in particular to a security warning indicator light. Background technique [0002] Many modern families use gas as kitchen fuel. Gas can easily cause carbon monoxide poisoning. Carbon monoxide poisoning is the product of incomplete combustion of carbon-containing substances and causes poisoning through respiratory tract inhalation. The poisoning mechanism is that the affinity between carbon monoxide and hemoglobin is 200-300 times higher than that between oxygen and hemoglobin, so carbon monoxide can easily combine with hemoglobin to form carboxyhemoglobin, which makes hemoglobin lose its ability and function to carry oxygen, causing tissue asphyxia. It has a toxic effect on the tissue cells of the whole body, especially the cerebral cortex. Therefore, once a gas leak occurs, it may cause extremely serious consequences. Most of the existing gas alarms on the market use loudspeaker alarms,...
