Abstract

The invention discloses a combustible gas alarm which comprises a circuit box used to store circuit components, a hanging frame and a guide frame disposed on the circuit box as well as a control circuit disposed in the circuit box, wherein the control circuit comprises a transformer which is connected to an alternating current source provided by an mains supply as well as a relay, a buzzer and a silicon controlled rectifier which are successively connected in series between a positive electrode output end of the transformer and a negative electrode output end of the transformer; a gas sensitive component is disposed on the top end of the circuit box, and the gas sensitive component is connected to a control electrode of the silicon controlled rectifier; and a normally open contact of the relay is connected to a water pump which is disposed in a liquid fire extinguishing agent. The combustible gas alarm disclosed by the invention has the advantages of a simple and reliable structure, good fire-prevention effects and applicability to household applications.

Description

technical field [0001] The invention relates to the security field, and specifically discloses a combustible gas alarm. Background technique [0002] Fire is one of the common disasters that threaten the safety of human life. Gas leakage is one of the most common causes of fire accidents. There are existing combustible gas alarms that can be used to detect the concentration of combustible gas in the air and give an alarm. However, the existing combustible gas alarms are usually connected to the door panel by screws, which greatly destroys the stability of the overall structure of the door panel. The hard performance of the door panel is reduced, and the protective effect is reduced. In addition, the existing combustible gas alarms are very complicated in structure and expensive, and are not suitable for ordinary households. Contents of the invention [0003] The present invention intends to provide a combustible gas alarm to solve the problem that the existing combustib...
