Snorkeling tube structure and method of manufacturing the same

A snorkeling tube structure, comprising:

• a tube body, formed by extending along an axis and comprising an outer surface and an inner surface opposite to the outer surface, wherein the inner surface encircles the axis to define an air passage;
• and
• a partition portion, extended along the axis, formed integrally with the tube body, and disposed on the inner surface to divide the air passage into an intake passage and an outtake passage;
• wherein at least one of the tube body and the partition portion has a thickness which is not greater than 3.0 millimeters.

A method of manufacturing a snorkeling tube structure, comprising:

• forming a parison, wherein the parison includes a first passage and a second passage separated to each other;
• placing the parison in a mold cavity of a mold;
• injecting air into the first passage and the second passage to inflate the parison towards a wall of the mold cavity;
• and
• removing the inflated parison from the mold to get a snorkeling tube structure.
