Portable overwater lifesaving ball

Abstract

The invention discloses a portable overwater lifesaving ball, and relates to an overwater lifesaving device. The portable overwater lifesaving ball comprises a container, an elastic bag, a stirrer, a rope winding device, a rope, a first foaming reaction solution chamber, a second foaming reaction solution chamber, a protection shell and a sealing film; the container is arranged in the protection shell, the elastic bag is arranged at the opening of the container, the elastic bag and the container are separated by the sealing film arranged at the opening of the container, the first foaming reaction solution chamber and the second foaming reaction solution chamber are arranged in the container, the first foaming reaction solution chamber and the second foaming reaction solution chamber are respectively filled with a foaming reaction solution used for generating a gas and a foaming reaction solution used for generating foam, the rope is wound on the rope winding device, the rope winding device is connected with the rotating shaft of the stirrer, and the rope is connected with the stirrer through the rope winding device. When the rope is pulled, the stirrer is driven by the rope winding device to rotate, and cuts the outer film packaging of the first foaming reaction solution chamber and the second foaming reaction solution chamber to mix and react the first foaming reaction solution in the first foaming reaction solution chamber with the second foaming reaction solution in the second foaming reaction solution chamber in order to generate the gas and foam.

Description

technical field [0001] The invention relates to a water lifesaving appliance, in particular to a portable water lifesaving ball. Background technique [0002] Usual water lifesaving equipment is mostly life jackets, buoy rings, or foam buoys, which are relatively large in size and generally only used when swimming, so it is inconvenient to carry them with you. Now there is an imported wrist-type life-saving device that can be automatically inflated. Although it has certain practicability and portability, it is dangerous because it uses high-pressure bottled liquid gas as the gas source, and its appearance and shape are not enough. Small and beautiful, it can only be worn when swimming, and the price is relatively expensive. Not many people buy and use it, and it cannot protect the crowd anytime and anywhere. There are also various inventions that generate gas through chemical reactions to automatically inflate the airbags, because they all have obvious defects, such as bulk...

[0002] The usual water lifesaving equipment is mostly life jackets, life buoys, or foam buoys, which are large in size and are generally only used when swimming, so it is inconvenient to carry them with you.

Now there is an imported wrist-type life-saving device that can be automatically inflated. Although it has certain practicability and portability, it is dangerous because it uses high-pressure bottled liquid gas as the gas source, and its appearance and shape are not enough. Small and beautiful, it can only be worn when swimming, and the price is relatively expensive. Not many people buy and use it, and it cannot protect the crowd anytime, anywhere

There are also various inventions that generate gas through chemical reactions to automatically inflate the airbags, because they all have obvious defects, such as bulky appearance and simple appearance, or the airbags are easy to break and have no safety guarantee, or contain toxic and harmful substances, which are not conducive to health and environmental protection, and cannot be used. To practical and effective protection, it is not easy to be accepted by the world, no manufacturer is willing to produce, and the product has not been seen in the world
