Abstract
The utility model discloses an under -voltage autoalarm is used to fire extinguisher, including bottle, valve and handle, the junction of bottle and valve be provided with the manometer, manometer interior including the metal pointer, the metal pointer is at the set threshold range internal rotation of atmospheric pressure, pivot and power, the buzzer siren electric connection of metal pointer, the manometer in still be provided with the metal contact, the metal contact sets up in the position of pressure metal pointer arrival during by set threshold value minimum, metal contact and buzzer siren electric connection, power, pivot, metal pointer, metal contact, buzzer siren form warning circuit. The beneficial effects of the utility model are that: 1, whether through the setting pressure table, it is sufficient clearly to understand the interior gas of fire extinguisher, 2, utilizing the pointer of manometer, designing warning circuit, when atmospheric pressure was less than set minimum threshold, the alarm switch -on was reported to the police.
Description
Technical field
This utility model is related to a kind of alarm device, particularly to a kind of under-voltage autoalarm of fire extinguisher.
Background technology
Fire extinguisher is a kind of portable Fire extinguisher.Chemical substance is placed, in order to rescue fire extinguishing calamity in fire extinguisher.Fire extinguisher is
One of common fireproofing installation, leaves public place or it may happen that filling in the place of fire, different types of fire extinguisher in
Composition different, be to aim at different fire alarms and set.Fire extinguishing appliance is that one kind is often treated coldly by people at ordinary times, shows greatly body during urgent need
The thing of the fire-fighting indispensability of handss.Especially stand in great numbers in high buildings and large mansions, indoor a large amount of timber, plastics, today of fabric decoration, once
There is the condition of a fire, there is no suitable fire extinguishing appliance, just may breed disaster.
But current fire extinguisher common problem is can not to show the pressure of the inside gas or liquid, in hypotony
Or do not have when pressure nor send the alarm and reminding relevant personnel in time to note, change.Therefore, research and development one kind can be at any time
Know fire extinguisher pressure inside the tank, and be that association area is urgently to be resolved hurrily in the fire extinguisher alarm device of pressure inside the tank deficiency alarm
Problem.
Utility model content
The purpose of this utility model is to provide for a kind of under-voltage autoalarm of fire extinguisher, to solve prior art
The problems referred to above.
The purpose of this utility model is achieved through the following technical solutions.
A kind of under-voltage autoalarm of fire extinguisher, including bottle, valve and handle；Described bottle and the company of valve
The place of connecing is provided with pressure gauge, described manometric interior include metal finger, described metal finger is in air pressure given threshold scope
Interior rotation；The rotating shaft of metal finger is electrically connected with power supply, buzzer siren；It is additionally provided with metal in described pressure gauge to touch
Point；Described hard contact is arranged at the position that pressure is reached by metal finger during given threshold minima；Described metal touches
Point is electrically connected with buzzer siren；Power supply, rotating shaft, metal finger, hard contact, buzzer siren form warning circuit.
Described power supply is aneroid battery or button cell.
It is provided with switch in described warning circuit, in order to close closed circuit when not in use, keep electric quantity of power supply.
In described warning circuit, necessary resistance is set, to adjust output.
This utility model utilizes the telegraph key effect that the pointer in pressure gauge is used as in series circuit with hard contact, works as fire extinguishing
When in device, pressure is sufficient, pointer is left with hard contact, and series circuit disconnects；When in fire extinguisher, pressure is inadequate, pointer turns
Dynamic, move closer to hard contact, when contacting metal contact, circuit ON, alarm rings.
The beneficial effects of the utility model are: 1, pass through to install pressure gauge, can be apparent from whether gas in fire extinguisher fills
Foot；2nd, utilize manometric pointer, design warning circuit, when air pressure is less than set minimum threshold, alarm is connected and reported to the police.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the principle schematic of warning circuit of the present utility model；
In figure, 1, bottle 2, pressure gauge 3, metal finger 4, rotating shaft 5, power supply 6, buzzer siren 7, metal touch
Point.
Specific embodiment
Of the present utility model construction featuress are expanded on further below in conjunction with the accompanying drawings with specific embodiment.
As depicted in figs. 1 and 2, the under-voltage autoalarm of a kind of fire extinguisher, including bottle 1, valve and handle；Described
Bottle 1 junction of valve is provided with pressure gauge 2, include metal finger 3, described metal finger in described pressure gauge 2
Pin 3 rotates in the range of air pressure given threshold；The rotating shaft 4 of metal finger 3 is electrically connected with power supply 5, buzzer siren 6；Described
Pressure gauge 2 in be additionally provided with hard contact 7；It is metal finger during given threshold minima that described hard contact 7 is arranged at pressure
The position that pin 3 is reached；Described hard contact 3 and buzzer siren 6 are electrically connected with；Power supply 5, rotating shaft 4, metal finger 3, gold
Belong to contact 7, buzzer siren 6 forms warning circuit.
Described power supply 5 is aneroid battery or button cell.
It is provided with switch in described warning circuit, in order to close closed circuit when not in use, keep electric quantity of power supply.
In described warning circuit, necessary resistance is set, to adjust output.
This utility model utilizes the telegraph key that the metal finger 3 in pressure gauge 2 is used as in series circuit with hard contact 7 to make
With when in fire extinguisher, pressure is sufficient, metal finger 3 is left with hard contact 7, and warning circuit disconnects；When pressure in fire extinguisher 2
When inadequate, metal finger 3 rotates, and moves closer to hard contact 7, when contacting metal contact 7, circuit ON, and alarm rings.
Claims (4)
