Portable fire extinguisher with voice prompt function

Abstract

The invention discloses a portable fire extinguisher with a voice prompt function. The portable fire extinguisher with the voice prompt function comprises a tank body and a warning device; the warning device comprises a loudspeaker, a control circuit and a detecting part for detecting state changes of the fire extinguisher; the loudspeaker and the detecting part are electrically connected with the control circuit respectively so that when the detecting part detects that the state of the fire extinguisher changes, the loudspeaker can produce a voice prompt. The warning device is installed on the tank body of the fire extinguisher so that the loudspeaker can produce the corresponding voice prompt when the detecting part detects that the state of the fire extinguisher changes, and the problem that existing fire extinguishers can not timely put out a fire when a fire disaster occurs can be avoided.

Description

technical field [0001] The invention relates to a portable fire extinguisher, in particular to a portable fire extinguisher with a voice prompt function. Background technique [0002] At present, ordinary places are equipped with portable fire extinguishers, but after a long period of storage in most places, the internal pressure of portable fire extinguishers is likely to be lower than the standard value due to factors such as pressure relief, so that they cannot be used normally, or they are prone to pressure due to high temperature As a result, its internal pressure is higher than the standard value, causing danger such as bursting. [0003] Because a considerable number of people have not received professional training, when a fire broke out, they used portable fire extinguishers and did not pull out the safety pin. As a result, the fire extinguishers failed to work in time and failed to extinguish the fire at the first time, resulting in the spread of the fire. Or in a...

Problems solved by technology

[0002] At present, ordinary places are equipped with portable fire extinguishers, but after a long period of storage in most places, the internal pressure of portable fire extinguishers is likely to be lower than the standard value due to factors such as pressure relief, so that they cannot be used normally, or they are prone to pressure due to high temperature Cause its internal pressure to be higher than the standard value, resulting in dangers such as bursting

[0003] Because a considerable number of people have not received professional training, when a fire broke out, they used portable fire extinguishers and did not pull out the safety pin. As a result, the fire extinguishers failed to work in time and failed to extinguish the fire in the first place, resulting in the spread of the fire.

Or in an emergency, if you forget to pull out the safety pin and press the fire extinguisher, the pressure handle of the fire extinguisher is seriously deformed, and the fire extinguisher is in an invalid state. After the safety pin is pulled out again, the pressure handle cannot be pressed normally, and the fire extinguisher will not work.

[0004] Obviously, after the above-mentioned ordinary portable fire extinguishers are placed for a long time, once a fire breaks out, the pressure is too low, and it is easy to spray a large amount of fire extinguishing agent in time, thus delaying the best time to extinguish the early fire, which will cause the fire to go too far. The consequences of area spread and direct economic loss; or potential danger due to excessive pressure

[0005] When the portable fire extinguisher is in use, due to the tension of the personnel, the best fire extinguishing time is delayed due to the function of the safety pin.

In addition, if the portable fire extinguisher is in a state of failure or semi-failure due to human misuse, the fire extinguisher will not be able to extinguish the fire immediately.
