Fire extinguisher red light alarm

Abstract

A fire extinguisher red light alarm includes a fire extinguisher cylinder body, a fixing leather ring, a spray nozzle, a handle, a safety pulling ring, and a pressure meter, which are connected to each other successively. A micro alarm is fixed to exterior of the pressure meter. A dial is installed in the pressure meter. A pointer is installed on the dial. A reed switch is installed at a position, which warns a value being lower than a minimum pressure, on the dial. A red light emitting diode is installed at the left lower part of the dial and a button battery is installed at the right lower part of the dial. The dial must be made from non-iron materials while the pointer must be made from a magnetic material. The fire extinguisher red light alarm can be used for conveniently and directly detecting pressure leakage, when the pressure of the fire extinguisher is lower than a warning value, the pointer of the pressure meter is moved into a red alarm zone. Because the pointer is magnetic, the reed switch is switched on, so that the red light emitting diode gives out light while the micro alarm gives out buzzer, which catches the attention and reminds people to deal with the fire extinguisher. The fire extinguisher red light alarm can achieve sound and light warning in a fire extinguisher of which the pressure is loss for reminding people to fill the fire extinguisher with agents, thereby ensuring safety.

Description

1. Technical field [0001] The invention relates to a fire extinguishing facility, in particular to a fire extinguisher red light alarm which is equipped with a dry reed switch, a red light emitting diode and a miniature alarm on the fire extinguisher pressure gauge. 2. Background technology [0002] With the improvement of people's living standards, safety awareness is getting stronger and stronger. In order to prevent fires, factories, supermarkets and other public places will be equipped with a certain number of fire extinguishers, but the agents in the fire extinguishers have a certain expiration date, and if they exceed the expiration date, they will lose pressure. In order to ensure that the fire extinguisher can be used normally in an emergency, continuous human inspection is required. If the failed fire extinguisher cannot be detected in time, it will cause a safety hazard. However, the inspection requires a lot of manpower and material resources, so it will only be ...

AI Technical Summary

Problems solved by technology

In order to prevent fires, factories, supermarkets and other public places will be equipped with a certain number of fire extinguishers, but the agent in the fire extinguisher has a certain expiration date, and if it exceeds the expiration date, it will lose pressure

In order to ensure that the fire extinguisher can be used normally in an emergency, continuous human inspection is required. If the failed fire extinguisher cannot be detected in time, it will cause a safety hazard

However, the inspection requires a lot of manpower and material resources, so it will only be inspected once a year, which will cause many fire extinguishers to lose pressure. No one knows that in case of a fire, the consequences will be disastrous
