Abstract

The utility model discloses an automatic gas-filling swimming ring, which is composed of a gas chamber and a small chamber which are connected by a flexible conduit; the gas chamber is open on both ends and is provided with a small quantity of sodium bicarbonate solution; the small chamber is provided with citric acid. The conduit is provided with a clamping element; the gas chamber is provided with a gas nozzle; the two annular ends of the gas chamber are buckled by a connecting element. The utility model can be girded on the waist as a stand-by life preserver. When the fortuitous event happens in water, the clamping element on the conduit can be pulled off. By pressing the small chamber, the citric acid flows into the gas chamber and generates reaction with the sodium bicarbonate to generate a large quantity of carbon dioxide which makes the gas chamber quickly expand and be inflated. Thus the goal of self-rescue in emergency is achieved.

Description

Automatic gas-filling swimming ring

The utility model is about a kind of water wing.

Water wing mostly is just that the swimmer uses, and for the people who has certain level, huge water wing is an impediment to the enjoyment of swimming, generally all is reluctant to be equipped with band, thereby when running into unforeseen circumstances, often causes unnecessary death because of not saving oneself.

The purpose of this utility model provides a kind of in case of emergency automatic gas filed water wing of being convenient to, and neither hinders the enjoyment of swimming under the normal circumstances, again can be when running into accident in water fast aeration save oneself, guarantee safety.

The utility model water wing is made up of the ring-shaped air chamber that a small amount of sodium bicarbonate solution is housed and the cell that citric acid is housed that communicates with flexible conduit with it of a both ends open, and conduit has clamping element, and air chamber is provided with valve, and annular two ends are with the attaching parts snapping.When unclamping clamping element, the interior citric acid of cell is flowed via a conduit in the ring-shaped air chamber, citric acid promptly produces great amount of carbon dioxide gas with reaction of sodium bicarbonate, and air chamber is inflated automatically rapidly and is heaved at this moment.

This water wing is worn in waist fully with the unaerated state, as emergency situation, only need draw clamping element after the entry, pushes cell and can inflate rapidly.

The utility model water wing is worn conveniently fully, and the enjoyment that does not hinder swimming under the normal circumstances can fast automatic under water inflation under the emergency, and is fool proof, also can directly blow from valve to the beginning swimmer, identical with general water wing effect.

Below in conjunction with description of drawings example structure of the present utility model.

Fig. 1 is this Facad structure scheme drawing of inflation water wing automatically.

Fig. 2 is the A-A section-drawing of Fig. 1.

As Fig. 1, Fig. 2 embodiment, this water wing is made up of a ring-shaped air chamber 1 and cell 5, and ring-shaped air chamber is provided with valve 2, and cell can be connected with the interface 9 of air chamber by flexible conduit 8 and communicates, and clamping element 6 is arranged on the conduit, and when not needing to inflate, clamping element opens circuit conduit.One section connecting band 3 is all stretched out at the two ends of ring-shaped air chamber, and being with velcro 4 is attaching parts.Water wing is provided with the collection wing 7(that links to each other with gas chamber outer wall and sees Fig. 1,2), wing tip is provided with and is velcro in the attaching parts 10(present embodiment), water wing not the time spent may be folded in the collection wing, the velcro of buckling both wings promptly becomes band, and is easy to carry and collects.The collection wing 7 can fuse with connecting band 3.

The use of this water wing is as follows: the sodium bicarbonate solution that pours into 100 grams, 50% concentration from valve 2 to air chamber 1, in cell 5, pour into 50 gram citric acids from conduit 8, close valve 2, clamp conduit 8 with clamping element, the other end with conduit is connected with air chamber again, but the two is not connected because of the effect of clamping element.The user is wrapped up in above water wing and is trapped among on the waist, with attaching parts annular two ends are connected and fixed, can entry swim, when meeting emergency situation, the user only need draw back clamping element, pushes cell with hand, make citric acid enter air chamber and sodium bicarbonate reacts rapidly by conduit, produce great amount of carbon dioxide, air chamber is expanded inflate, can make the person in distress out of danger.

Claims

1, inflates water wing automatically, it is characterized in that forming with a cell that citric acid is housed 5 that links to each other with flexible conduit 8 with it by the ring-shaped air chamber that a small amount of sodium bicarbonate solution is housed 1 of a both ends open, conduit has carries part 6 secretly, and air chamber is provided with valve 2, and annular two ends are with attaching parts 4 snappings.

2, automatic inflation water wing as claimed in claim 1 is characterized in that being provided with the collection wing 7 that links to each other with the outer wall of air chamber 1, and wing tip is provided with attaching parts 10.
