Portable water life-saving ball

Abstract

The invention discloses a portable water life-saving ball, and belongs to the field of water life-saving appliances. The portable water life-saving ball comprises an elastic airbag, a container and awater inlet pipe. The container is arranged in the elastic airbag, a water inlet is formed in the elastic airbag, the water inlet pipe is arranged between the water inlet and the container to communicate the water inlet with the container, and a permeable membrane separator with fine through holes is arranged between the water inlet pipe and the container. A one-way water inlet valve enabling water to flow into the container is arranged at the water inlet. Kerosene or paraffin oil is placed in the container, and alkali metal is soaked in the kerosene or paraffin oil. Expandable graphite and adhesives are placed into a space formed between the container and the elastic airbag, and inert gases are poured into the space. The portable water life-saving ball is small in size, convenient to operate, high in safety, capable of rapidly expanding, stable and firm.

Description

technical field [0001] The invention relates to the field of water lifesaving appliances, in particular to a portable water lifesaving ball. Background technique [0002] The usual water lifesaving equipment is mostly life jackets, life buoys, and foam buoys, which are relatively large in size and are generally only used when swimming, so it is inconvenient to carry them with you. There are self-inflating wrist-type lifesaving equipment on the market. Although it has certain practicality and portability, it is dangerous because it uses high-pressure bottled liquid gas as the gas source, and its appearance is not small enough. It can be worn while swimming, and the price is relatively expensive. There are not many people who buy and use it, and it cannot protect the crowd anytime and anywhere. There are also various technologies that generate gas through chemical reactions to automatically inflate the airbags. Because of their obvious defects, they are either bulky and simpl...

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

There are self-inflating wrist-type lifesaving equipment on the market. Although it has certain practicality and portability, it is dangerous because it uses high-pressure bottled liquid gas as the gas source, and its appearance is not small enough. It can be worn while 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 technologies that generate gas through chemical reactions to automatically inflate the airbags. Because of their obvious defects, they are either bulky and simple in appearance, or the airbags are easy to break, and their safety is not guaranteed, or they contain toxic and harmful substances that are not healthy and environmentally friendly. unable to provide effective protection
