Fire alarm device for power patch board

Abstract

The invention discloses a fire alarm device for a power patch board. A power plug of the fire alarm device is arranged on the bottom face of a shell, a flame, smoke and temperature detection circuit, an audible and visual alarm, a relay module and a power module are integrated in the shell, and a display module is arranged on the top face of the shell and connected with the temperature detection circuit and the power module. The flame and smoke detection circuit monitors open fire and smoke in the surrounding environment in real time and is connected with the audible and visual alarm, the temperature detection circuit monitors the temperature of a copper bar in the power supply patch board and is connected with the audible and visual alarm, the input end of the power supply module is connected with the power plug, and the output end provides a working power supply for the device. The relay module comprises a first relay and a second relay with normally open contacts, coils of the first relay and the second relay are connected with a flame and smoke detection circuit, and the normally open contacts are connected in series and then connected with two ends of a power plug. The device detects open fire and smoke in the surrounding environment and the temperature of the copper bar in the patch board in real time, automatically cuts off a superior power switch, and ensures personal and property safety.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a fire alarm device for a power strip. Background technique [0002] With the popularity of electrical products and the increase in power, fire accidents caused by power strips occur frequently. If the early fire danger is not detected in time, and the power switch is not turned off in a panic, the fire will expand and cause serious personal safety. Dangerous and serious economic loss. [0003] In today's society, all kinds of electronic products, household appliances and electric vehicles are more and more widely used, and the plugs of various mobile phone chargers and other household appliances have been plugged into the power strip. Especially when charging electric vehicles, the charging time is long. The charger generates a large amount of heat, and long-term power-on will cause the internal components of the charger to age and fail, especially when people are asleep at n...

[0006] The plug-in boards of the above-mentioned patent documents are all special custom-made plug-in boards. The ordinary plug-in boards purchased in the market cannot be used through addition or modification. The special custom-made plug-in boards are expensive and not widely available; The limitations of the system, for example, it can only monitor the temperature of a certain part of the power strip or only the electrical appliances, but cannot monitor the temperature of the power strip itself and the internal copper bar; and only has the function of temperature monitoring, without the function of smoke and flame detection
