Abstract

The utility model relates to a pneumatic swimming ball, which is characterized in that the device comprises a main vessel in which a liquid reactant is arranged. A seal cork is arranged in the opening of the main vessel with the head of the cork protruding the opening of the vessel. A solid reactant is arranged outside the main vessel and a latex jacket which encases the main vessel, cork, and solid reactant completely; the liquid reactant and solid reactant can, after being mixed, yield tons of gas through a quick chemical reaction. The pneumatic swimming ball is designed to be carried by swimmers in swimming. Once the swimmer is in dangerous status that the legs or feet are cramped or the mouth or nose is choked by water or the body is sunk for exhausted, or the body is rushed by the rush, the ball becomes a big balloon to raise the head of the swimmer out of water to restore breath, thus the swimmer is prevented from drowning. The pneumatic swimming ball has the advantages of convenient portability, easy use, excellent quick life preserving performance, simple structure and low manufacturing cost.

Description

The swimming lifesaving ball

Technical field

The utility model relates to the fast life-saving device that a kind of swimmer of convenience uses in the swimming process, particularly a kind of swimming lifesaving ball.

Background technology

Present existing lifesaving appliance, a kind of is device as buoy quoit or liferaft and so on, and its gas of just must substituting the bad for the good earlier before use so not only portably uses inconvenience, and for natatory people, carry bulky like this device it can't normally be swum.Also have a kind of lifesaving appliance to constitute by compression foam, before not putting into water as yet, this device is compressed into a very little thing of volume under external force, in case put into water, imbibition at once becomes a very big floating debris, thereby succours the drowning person fast; But because this device is as long as one meet water and promptly expand, and the swimmer just need use lifesaving appliance when only in the swimming process emergency episode taking place, other the time do not need to use, so be unfavorable for that also the swimmer carries use in the swimming process.

The utility model content

In order to solve existing in prior technology the problems referred to above, the utility model provides a kind of swimming lifesaving ball, the swimmer can carry it in the swimming process, in case legs and feet cramp spasm takes place in the swimmer, perhaps the mouth and nose water of choking suffocates, the sinking of perhaps being short of physical strength, perhaps torrent washes away hour of dangers such as health, this swimming lifesaving ball can form fast can hold out swimmer's head the large balloon of the water surface with second wind, thereby it is drowned dangerous to make things convenient for the swimmer to break away from fast, it is not only easy to carry, operate simple and easy, fast life-saving is effective, and simple in structure, low cost of manufacture.

The technical solution of the utility model is to constitute like this, it is characterized in that: it comprises that an internal storage has the primary tank of liquid reactants, the opening of primary tank is provided with packed-piston, piston crown stretches out the primary tank opening, the primary tank outside be provided with solid reactant and with primary tank, piston, the whole sealed envelope of solid reactant at interior rubber finger sleeve; But described liquid reactants and solid reactant are respectively two kinds of reactive materials that rapid reaction after the mixing generates a large amount of gases.

During swimming, the swimmer can hang over the shirtfront with the utility model swimming lifesaving ball, legs and feet cramp spasm takes place in the swimming process, perhaps the mouth and nose water of choking suffocates, the sinking of perhaps being short of physical strength, perhaps torrent washes away hour of dangers such as health, the swimmer needn't be panic, can keep strokes on one side, do in short-term on one side and hold one's breath, with the hands piston is separated with the opening of primary tank fast simultaneously, liquid reactants in the primary tank is flowed out, the solid reactant outer with primary tank reacts and rapid gas generating, force rubber finger sleeve to expand and become large balloon, thereby swimmer's head is held out the water surface and it is normally freely breathed.After the swimmer breaks away from drowned death risk, can patience wait rescue or swim back to the shore voluntarily.Than prior art, the utility model is not only easy to carry, operation is simple and easy, fast life-saving is effective, and simple in structure, low cost of manufacture, is very suitable for vast swimming fan and uses.

In the technique scheme; in order to make liquid reactants and fixation reaction thing after mixing, reaction at once generate gas; thereby avoid delay the lifesaving time; described liquid reactants is preferably hydrogen peroxide; solid reactant is preferably manganese dioxide particle or powder (also can adopt other reactive material certainly, but the possibility speed of response can be slower).Through evidence, but generate a large amount of oxygen with immediate response after manganese dioxide mixes when hydrogen peroxide, and the preferable content proportioning of hydrogen peroxide and manganese dioxide is: concentration is 70% hydrogen peroxide 60ml～80ml, manganese dioxide 3g～5g.Rubber finger sleeve can expand rapidly under the gaseous tension effect and become big balloon as the basketball during reaction, the swimmer head of body weight below 150 kilograms can be held out the water surface and it is normally freely breathed.Can adjust the content proportioning of hydrogen peroxide and manganese dioxide when certainly, specifically using according to user's body weight weight.

The utility model further improvement in the technical proposal is: the head that piston stretches out the primary tank opening is provided with the auxilliary container of volume less than primary tank, primary tank at the buoyancy in the water greater than auxilliary container so that primary tank remains downward opening state in water, be primary tank vertically towards the water surface, and auxilliary container is vertically towards the bottom.Like this when the outside auxilliary container of pulling, when piston is separated with the opening of primary tank, the liquid reactants in the primary tank be by gravity from opening automatically toward dirty, react and mix with the outer solid reactant of primary tank.

Above-mentioned solid reactant can be positioned in the auxilliary container, is distributed with through hole at auxilliary container on the wall shell of primary tank opening; Perhaps described solid reactant also can be positioned over the open outer side of primary tank or be distributed in primary tank or the wall of container outside face of auxilliary container.If solid reactant is to be positioned in the auxilliary container, then when piston separates with the primary tank opening, the hand of holding auxilliary container under water loosens slightly slowly, in about 3 seconds, liquid reactants in the primary tank just by gravity flows out the primary tank opening rapidly, then the through hole that passes on the auxilliary wall of container shell flows in the auxilliary container, generates gas with the solid reactant hybrid reaction.

In addition, when rubber finger sleeve causes breakage because of unforeseen circumstances, (for example the swimmer carries it and swam but do not carry out the lifesaving purposes to continue to use the utility model swimming lifesaving ball for fear of the user under unwitting situation, before using for the second time rubber finger sleeve may produce breakage and the user and do not know), the outer cover that is preferably in described rubber finger sleeve is equipped with one deck breakage-proof diaphragm seal cover, is filled with little air between diaphragm seal cover and the rubber finger sleeve.Like this when air when forfeiture that is filled between diaphragm seal cover and the rubber finger sleeve, can remind this rubber finger sleeve of user might be damaged, the user should carefully use.And when rubber finger sleeve expanded, the diaphragm seal cover was easy to just break.
