Abstract

PURPOSE:To provide a snorkel which does not require the special effort for erecting an air suction cylinder and holding an air taking-in port at the top edge on water and prevents the air taking-in port from being drenched, even if waves are formed on the water surface. CONSTITUTION:A number of air talking-in small holes 13 are formed on the upper semisphere 11 of a hollow hard plastic sphere 10, and in the plastic sphere 10, an air suction cylinder 20 whose upper part is bent in an inverted U shape from the pole point 14 of the lower semisphere 12 and has the air taking-in port 21 opened downward at the top edge is insertion-fixed in watertight manner. The upper edge of a bendable hose 30 which is joined with a branched pipe 31 for discharging air is connected with the lower edge of the air suction cylinder 20 which projects in the lower part of the plastic sphere 10. The check valves 41 and 42 are installed between the upper edge of the hose 30 and the branched parts 32 and 31.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved snorkel that can freely move around in water.

[0002]

2. Description of the Related Art Conventionally, as one that can breathe while submerged in water, an air intake provided at the tip of a cylinder is brought out above the water surface, and one end of a hose for guiding air is connected to the lower end of the cylinder. In addition, the snorkel is designed so that the air taken in from the air intake port is sucked in through the mouth, and the air is taken in through the nose while breathing while keeping the face under the surface of the water, such as putting the other end in the mouth.

However, the above-mentioned conventional snorkel is not self-supporting, and it is difficult to stand up the cylinder and hold the air intake port stably on the surface of the water. There is a problem that water may get into the mouth from the intake port, and it may cause suffocation.

[0004]

The problem to be solved is that in the conventional snorkel, the cylinder falls or is covered with waves, water enters from the air intake port, and it becomes almost suffocating. There is something that happens.

[0005]

According to the present invention, a large number of small air intake holes 13 are provided in an upper hemisphere 11 of a hollow hard plastic sphere 10, and a plurality of small holes 13 for air intake are provided in the plastic sphere 10 from a pole point 14 of a lower hemisphere 12 thereof. , The upper part is bent in an inverted U shape, and the air suction cylinder 20 having the air intake port 21 opened downward at the tip is watertightly inserted and fixed to the lower end of the air suction cylinder 20 protruding below the plastic ball 10. , The upper end of the bendable hose 30 to which the air discharge branch pipe 31 is connected, and the upper end of the hose 30 and the branch portion 3
The check valves 41 and 42 are provided between the valve 2 and the branch pipe 31, respectively.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to the drawings.
0 is a hollow hard plastic ball having an inner diameter of 150 to 200 mm, 13 is a large number of small holes for air intake of about 1.5 mm on the upper hemisphere 11 of the hollow hard plastic ball 10, and 20 is an air suction tube. And the plastic ball 10
The lower hemisphere 12 is inserted and fixed in a watertight manner from the pole 14 of the lower hemisphere 12, the upper part is bent in an inverted U shape, and an air intake port 21 opened downward is provided at the tip. Reference numeral 30 denotes a bendable hose having an upper end connected to a lower end of an air suction cylinder 20 protruding below the plastic ball 10 and having a length of 1 to 1.5 m.
Has been formed. Note that 41 and 42 are both check valves, and between the upper end of the hose 30 and the branch portion 32, and water enters the hose 30 side so that the air discharged to the air intake cylinder 20 side does not flow backward. It is provided in each branch pipe 31 so as not to exist.

The operation will be described. When the user 50 holds the hose 30 in his hand and puts the lower end of the hose 30 on the mouth 51 (holds it) and dives into the water, the plastic ball 10 having a specific gravity smaller than that of the water floats on the water surface 52. The air intake 21 is always kept above the water surface. Therefore, the user can
Is not required to stand vertically or to hold the air intake 21 at its tip above the water surface. When the user breathes, the air on the water surface is taken into the plastic ball 10 through the small hole 13 of the plastic ball 10, and is inhaled into the lungs of the user 50 from the air intake port 21 through the air intake cylinder 20 and the hose 30. The discharged air passes through the branch pipe 31 to form bubbles and is discharged into the water. Even if the surface of the water is ruffled, the water does not enter through the air intake port 21 of the minute hole just by washing the plastic ball 10, and it is possible to dive into the water and move around with confidence.

[0008]

Since the present invention is constructed as described above,
It is not necessary to make a special effort to stand the air intake cylinder 20 vertically or to hold the air intake port 21 at its tip above the water surface. Even if the water surface rises, water can enter from the air intake port 21. Instead, you can dive in the water and move around with peace of mind.
