The principle of work and the course of work of the utility model anti-drowning alarm are as follows.

In a single day sensor 102 meets water, will start the counter of single-chip microcomputer, begins the entry time of accumulative total sensor 102: if sensor 102 surfaces, and the cumulative time does not reach 27 seconds words, then sensor 102 can cut out single-chip microcomputer, and until entry once more, this moment is counting again; When sensor is dipped in the water when continuing 27 seconds, single-chip microcomputer will send alarm control signal, and launches electromagnet 301 with what this signal was passed to ball float catapult-launching gear 200, starts thus and reports to the police.

The effect of launching electromagnet 301 is to launch warning ball float 303.Under normal circumstances, the warning ball float 303 that permanent magnet 302 is installed can be inhaled with the iron core that launches electromagnet 301 tightly mutually, can not break away from iron core when normally swimming.When single-chip microcomputer provides the controlling alarm electric signal, launch electromagnet 301 and produce the powerful magnetic force of moment, the magnetic force generation repulsive force with permanent magnet 302 launches away warning ball float 303.The similar magnetic artillery principle of this process as long as it is identical with the magnetic pole of permanent magnet 302 to launch the magnetic pole of electromagnet 301 generations, will be launched away the warning ball float that has permanent magnet 302 by launching electromagnet 301.

Launched that warning in the water outlet is floating asks 303, owing to lost the effect of magnetic force, thereby under buoyancy function, can move upward.Meanwhile, report to the police to float and ask 303 built-in LED flashing circuits just to be activated, made the LED lamp of warning effect constantly glimmer.When warning ball float 303 was bubbled through the water column, the LED blinking light will the tip ground personnel, finish the warning effect thus.This moment, the ground staff can determine the residing position of drowning person rapidly according to the position of ball float, provided valuable time for the rescue personnel sues and labours.

The anti-drowning alarm of present embodiment judges that whether a people is drowned, judges by calculating a people the breathless time.But this judgement is a false judgement, because the time that ceases breathing that everyone drowns all is different.In fact, some people can occur did not all have to drown in lasting 27 seconds, but the situation that alarm is still reported to the police.Send at alarm and to report to the police but people when drowned again, it is reported to the police and is very easy to remove, this moment if warning ball float 303 be reinstalled the former iron core that launches electromagnet 301 then can, anti-drowning alarm can continue again to use afterwards.Reusable like this, reach do not waste, effect in energy saving and environmental protection.

Above-mentioned anti-drowning alarm be worn on the nostril with the upper part then can, it combines with contact lens, finally integrates a kind of anti-drowned swimming glasses.A kind of simple mode is that entry pick-up unit 100 is installed on the picture frame of these anti-drowned swimming glasses, and the anti-drowned swimming glasses that form thus have characteristics simple in structure, that price is lower, reliability is high, security is good.
