Floating ball of an underwater breathing apparatus for a diver

Abstract

A floating ball of an underwater breathing apparatus has a hollow housing, a base, a weighted block and a tube. The base is formed on the bottom of the hollow housing. The weighted block is attached to the bottom of the base or under the base. Multiple through holes are defined in the housing. Multiple vents are defined in the housing and above all of the through holes. The tube extends into the housing to a position near the top of the housing. The tube is connected to a hose connected to a mouthpiece on the other end. Consequently, the center of gravity of the floating ball is lowered and always kept in the bottom of the housing. The floating ball is not easily turned over by waves. In addition, the seawater entering the housing can be automatically drained off through the through holes.
