Abstract

The utility model relates to an automatically inflatable on-water life-buoy, which comprises an air bag. The air bag is provided with citric acid and sodium bicarbonate which are separated mutually by folding the air bag, and the casing of a folding air bag is provided with a packaging bag. The automatically inflatable on-water life-buoy can be dispersed by tearing and taking off the packaging bag of the outside of the air bag when used; the two kinds of liquid medicine can put together independently and can generate stable gas after reacts; the utility model does not need manual aerating when used. The utility model has the advantages of easy use and convenient portability, and the size of a folded automatically inflatable on-water life-buoy is only like the size of a cigarette box.

Description

Automatically inflatable on-water life-buoy

The utility model relates to aquatic life-saving equipment.

The widely used aquatic life-saving equipment of people mainly is buoy quoit and life jacket at present.Mainly contain two kinds, a kind of need are gas filed, before using, to inflate in advance, make troubles to use, another kind is to fill stiff foam material in it, though the each use of this kind version needn't be inflated separately, but structure is huge, carry inconvenience, in order to address this problem, people have done multiple effort, number disclose the patent application that a key name is called " miniature water life saving apparatus " as Chinese patent " 92226777.4 ", this utility model is by bottom, the container of inner/outer tube and filling calcium carbide is formed, and the inner/outer tube that container has perforate up and down connects, the mud post is softening in the buoyant apparatus entry, the following hole that inner core glides and opens urceolus under action of the spring, water enter container and the calcium carbide generated reactive gas makes airbag aeration produce the purpose that buoyancy reaches lifesaving, and this device has been realized automatic inflation, but the shortcoming that exists is a complex structure, the manufacturing cost height.

Task of the present utility model is: design a kind of simple in structurely, volume is little, and is easily manufactured, and cost is low, can gas filed automatically small-sized water life saving apparatus.

Task of the present utility model realizes as follows: buoyant apparatus comprises an air bag, and airbag fold just with separated into two parts space in it, is injected citric acid CH in the part ₂COOH and sodium bicarbonate NaHCO ₃

C（OH）COOH

CH ₂·COOH

Be covered with packaging bag at folding air bag, air bag is provided with air-filled pore, has fastened tether.

Its automatically inflation principle be: the buoyant apparatus outer packaging bag tears air bag unfold after, under the effect of gravity and current, two kinds of soups lump together automatically, the reaction back generates stable gas, and buoyant apparatus is filled up automatically, its reaction equation is as follows:

CH ₂·COOH CH ₂·COONa

C（OH）COOH ＋3NaHCO ₃→C（OH）·COONa＋3CO ₂

CH ₂·COOH CH ₂·COONa＋3H ₂O

The entire reaction time is not more than 30 seconds, and employed two kinds of liquid and reacted resultant are to the equal zero damage of any article.

The utility model is owing to be equipped with citric acid and two kinds of liquid of sodium bicarbonate in air bag, drawn bad at outer packaging bag like this, buoyant apparatus scatters, two kinds of soups lump together automatically, the reaction back generates stable gas, without the manual inflation, the buoyant apparatus after folding has only the cigarette case size, carries very convenient when using like this.

Fig. 1 is the utility model front view;

Fig. 2 is the birds-eye view of Fig. 1;

A most preferred embodiment of the present utility model, as figure, the air bag 1 of buoyant apparatus, can select for use plastics or waterproof nylon silk to make, its shape can be annular arrangement or oval ring, the half volume place in it is at first injected behind the citric acid 2 it is folding, injects another kind of soup sodium bicarbonate 3 in second half volume, in the packaging bag of packing into behind its foldable integral, just finished whole manufacture craft.For can repeated use, on air bag, can be provided with air-filled pore 4.

When people need use buoyant apparatus, directly draw the rascal pack with hand, air bag fills up, and just can use.

Claims

1, a kind of buoyant apparatus, it comprise an air bag and on the air-filled pore that has, have tether on the air bag, of the present utility model being characterised in that: the citric acid and the sodium bicarbonate of isolating mutually by airbag fold are housed in the air bag, are covered with packaging bag at folding air bag.
