Abstract
The utility model relates to a household alarm apparatus. The existing known gas tank has a high fluidity, a gas tank leakage alarm apparatus capable of being moved, installed and unweaved out conveniently does not exist at the current market, in order to overcome the defect, the utility model provides a mobile gas tank alarm apparatus, thus the effects of moving, installing and unweaving out conveniently can be achieved. The circuit of the mobile gas tank alarm apparatus shows that when the gas tank leaks and the harmful concentration in the air around the tank exceeds a standard, the electrical conductivity between a gas sensor A and a gas sensor B is increased rapidly, the pin 3 of a time base circuit block is changed to be high and flat, an oscillator starts to oscillate, and a loudspeaker gives out alarm sound; an alarm box is internally provided with a charger, a lithium ion battery, an alarm apparatus circuit board, a retractable plug, a charge indicating lamp and a work indicating lamp, the strip-type window in the box surface is internally provided with the loudspeaker, the air convection windows of the alarm box end surface and the two sides of the box surface are internally provided with gas sensors, and the bottom surface outside the box is provided with magnet strip bases which are used for positioning and installing.
Description
Technical field
The utility model relates to a kind of alarm.
Background technique
Present known gas-tank mobility is large, also be provided with on existing market a kind of, removable, gas-tank be installed, split out all very easily let out alarm.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of portable gas-tank leakage alarm, just can reach removable, install, splits out all gas-tank leakage alarm very easily.
technical side's peace that the utility model solves its technical problem is: by warning circuit, be provided with the portable gas-tank leakage alarm that location and installation uses the warning box of magnet strip seat to form, shown in its circuit: the power plug that can take in release, the charging work indicator light, charger, lithium ion battery, power switch, form power pack, gas sensing member and potentiometer form Detection Circuit, its peripheral cell of time base circuit piece forms multi-vibrator, when gas-tank when leaking, gas sensing member A, between B, specific conductance is very little, due to the output voltage of potentiometer sliding contact less than 0.7V, 4 pin of time base circuit piece are resetted by force, vibration is in off position, alarm not sounding rings, when gas-tank leaks, during harmful concentration over-standard in the tank ambient air, A, specific conductance between B increases sharply, time base circuit piece 3 pin become Gao Ping, the pierce circuit starting of oscillation, loudspeaker sends chimes of doom, its structure is: the warning box that is provided with the magnet strip seat, magnetic is held up on the switch valve and the decompression valve disc between air outlet adapter that is arranged on gas-tank, the release taken in plug in drawing handle on the end face chute of warning box and warning box is connected, plug is connected with charger by wire, charger is connected with the lithium ion battery that is arranged on the warning box inner bottom surface by wire, lithium ion battery, by the power switch on the warning box face, with the alarm circuit plate power supply that is arranged on top in warning box, charging work indicator light and work indicator light are housed on warning box, loudspeaker is installed in marking shape window, it is characterized in that: warning box, end face, the box face, both sides all have the cross-ventilation marking shape window, gas sensing member is installed in window, the outer both sides, bottom surface of warning box respectively be equipped with one be connected with the bottom surface of warning box the location arranged, the magnet strip seat of installation effect.
The beneficial effects of the utility model are: it is very easy that movement splits out installation, being particularly suitable for the large gas-tank of mobility uses, this product is self-powered is round-the-clock monitoring leakage, exceed standard if any leakage and report to the police immediately, reminding user is taked corresponding measure, in case the generation of human injury, this small product size is little, reliability is high, and is easy to use.
