Benefits of technology

The present invention is a new type of diving snorkel and upper exhaust head that solves the problem of poor sealing in the prior art. It uses a recess with a pivot seat that is connected to a float and partially fitted into an air hole. The sealing ring on the atmosphere of the float leans against the outer surface to form a tight seal preventing water from entering the air hole when the float is underwater. When the float is exposed to the water surface, it opens up the air hole so that the diver can breathe normally. This results in a better airtight effect and improved breathing experience for divers.

Problems solved by technology

As a result, the diver may have an accident.
This is dangerous for diving.
However, the sealing effect is not good.

Embodiment Construction

[0020]Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

[0021]Referring to FIG. 1 to FIG. 5, a specific structure of a preferred embodiment of the present invention comprises an air tube 10, a mouthpiece 20, and an upper exhaust head 30.

[0022]The mouthpiece 20 is connected to a lower end of the air tube 10. The upper exhaust head 30 is connected to an upper end of the air tube 10. The air tube 10, the mouthpiece 20 and the upper exhaust head 30 have a passageway therein to communicate with each other.

[0023]The upper exhaust head 30 includes a main body 31 and a float 32. The main body 31 has a recess 301 and an air passage 302. An upper end of the recess 301 is provided with an air hole 303 communicating with the air passage 302. The periphery of the air hole 303 is provided with a sealing ring 34. Specifically, the periphery of the air hole 303 radially extends to form an engaging ring 35. The sealing rin...

Abstract

A diving snorkel and an upper exhaust head thereof are provided. The upper exhaust head includes a main body and a float. The main body has a recess and an air passage. An upper end of the recess is provided with an air hole communicating with the air passage. A periphery of the air hole is provided with a sealing ring. The recess is provided with a pivot seat thereon. The float is rotatably disposed on the recess. The float has a pivot portion. The pivot portion is pivotally connected to the pivot seat.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to a diving device, and more particularly to a diving snorkel and an upper exhaust head thereof.2. Description of the Prior Art[0002]A conventional snorkel having a water discharge structure comprises a main body, a mouthpiece, a threaded pipe, a ring, and a pipe. When the diver bites the mouthpiece and dives into the water, the air inlet is above the water so that the diver can obtain the fresh air from the breathing tube without interrupting water activities because the diver needs to come out of the water for air. When the diver dives in the rough sea water or dives deeper, the water may flow into the snorkel form the air inlet. As a result, the diver may have an accident. This is dangerous for diving.[0003]The sealing structure of the conventional upper exhaust head uses a cover to cover the air hole. The cover ascends under the action of buoyancy to cover the air hole so as to prevent the wa...
