Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for underwater breathing having a simple structure, and further, a floating type underwater breathing device that does not allow water to enter the inside thereof and therefore does not need to blow out the water inside, that is, an improved snorkel. It is about.

[0002]

[Prior art]

 The conventional underwater breathing apparatus (snorkel) mainly consists of a cylinder made of a hard material and a mouthpiece made of a flexible material. These snorkels exert their breathing function only in the range near the water surface that the length of the cylinder allows.

[0003]

[Problems to be solved by the device]

 Therefore, the user of the conventional snorkel must hold his / her breath when diving deeply into the water (usually about 30 cm or more), and for breathing, he / she floats near the surface of the water and first blows out the water in the cylinder. However, it was necessary to breathe fresh air and dive again, and these series of actions consumed the energy of the user, and the amount of breathable air was limited.

Accordingly, it is an object of the present invention to provide a levitation type underwater breathing apparatus which does not require the user to be exposed to the surface of the water for breathing or blowing water in the device, unlike a conventional snorkel. Especially. An object of the present invention is to provide a self-levitation type underwater breathing apparatus (snorkel). The advantage of the breathing apparatus of the present invention is that water does not enter inside the apparatus, and the user is close to the water surface for breathing. It is not necessary to return to (about 30 cm below the surface of the water).

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention comprises a waterproof cap, an air chamber, a long tube, and a mouthpiece assembly. Specifically, the invention according to claim 1 is "a levitating underwater breathing apparatus, wherein (1) an upper part is sealed, a lower part is opened, and a plurality of air holes are provided on a side part. (2) It is an air chamber that is a substantially hemispherical hollow body with a flat bottom, and has an air intake part protruding from the center of a hollow cylindrical body installed at the top and a bottom. An air chamber having an air discharge portion provided, (3) a long tube having an elastic portion that can be freely expanded and contracted freely at the user's discretion, and (4) a curved tube portion and a mouse connected to the tube. A mouthpiece assembly comprising a piece, the mouthpiece assembly having one end of the curved tube portion connected to the mouthpiece, the mouthpiece including two chewing members, and a breathing port. The bottom opening of the waterproof cap is the hollow circle. The sides of the body engagement contact engagement, the air intake portion of the hollow cylindrical body levitation type underwater breathing apparatus, characterized in that you are positioned above the air hole of the waterproof cap. "Is.

[0006]

[Action]

 With the above configuration, the hollow air chamber gives buoyancy to this device and preliminarily preserves air. The waterproof cap on the air chamber does not allow water to enter the air chamber and allows only air to be taken in from the air intake. The long tube has a stretchable part that can be stretched and stretched, and can be extended underwater. Since this device does not allow water to enter the pipe, it does not require the operation of draining during breathing, and the user can easily breathe deep in the water.

[0007]

【Example】

 Hereinafter, a floating type underwater breathing apparatus according to the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1 to 3, the underwater breathing apparatus of the present invention has a water-proof cap 1, an air chamber 2, a long tube 3 and a mouthpiece assembly 4, which are the main members.

As shown in FIGS. 1 and 3, a cylindrical waterproof cap 1 has an upper end sealed and an opening 12 at the bottom, and a lower peripheral edge at the lower end. A plurality of air holes 11 are provided. The opening 12 at the bottom of the waterproof cap 1 is fixed on the top opening of the air chamber 2. The air chamber 2 is a substantially hemispherical hollow body, and a hollow cylindrical body 21 is formed in an upper opening thereof so as to project upward. Further, an air intake portion 22 is formed at the upper center of the hollow cylindrical body 21 and extends upward. The air intake port at the upper end of the air intake unit 22 is located above the air hole 11 of the waterproof cap 1 to prevent water entering from the air hole 11 from entering the air intake port of the air intake unit 22.

A cylindrical air discharge portion 23 is formed at the bottom of the air chamber 2 and extends downward. As shown in FIGS. 1 and 2, the long tube 3 has a stretchable portion 31 that can be stretched and bent freely. The upper portion of the long tube 3 is in communication with the air discharge portion 23, and the lower portion of the long tube 3 is in communication with the mouthpiece assembly 4. The connection between the long tube 3 and the mouthpiece assembly 4 is heavier than water, and the mouthpiece assembly 4 floats in water depending on the length of the long tube 3.

The mouthpiece assembly 4 has a curved tube portion 41 and a mouthpiece 42. One end of the curved tubular portion 41 is engaged and communicated with the long tube 3, and the other end thereof is connected to the mouthpiece 42. The mouthpiece 42 has two chewing members 43 and a breathing port 44.

When the long tube 3 is sufficiently long, the user of the device dives, for example, about 3 m below the surface of the water, holds the mouthpiece assembly 4 in his / her mouth, bites the biting member 42 with his / her teeth, and holds the mouthpiece 42. Secure in mouth. In this case, the air chamber 2 is floating above the water surface. During breathing, the air inhaled by the user enters the waterproof cap 1 through the air hole 11, further enters the air chamber 2 through the air intake portion 22, and further passes through the air exhaust portion 23. It goes into the long tube 3 and finally into the mouthpiece assembly 4. As shown in FIG. 3, the air hole 11 in the lower part of the waterproof cap 1 is located below the air intake of the air intake part 22. Therefore, the water entering from the air hole 11 due to waves on the water surface is not removed from the air hole 11. It is re-emitted through and does not enter the air chamber 2.

The inside of the air chamber 2 is hollow, so that the upper part of the device can be floated above the water surface by buoyancy. Further, air is stored in the air chamber 2, and continuous breathing is possible even if the water surface is a little rough. In addition, the novel underwater breathing apparatus of the present invention does not need to blow out water in order to prevent water from entering the inside of the pipe 3, so that the user of this apparatus floats near the water surface for breathing. You don't have to. The present invention is not limited to the above-described embodiment, and the shape, dimensions, materials, and quantity of each part such as the air chamber 2, the tube 3, the expansion / contraction part 31, and the mouthpiece assembly 4 can be appropriately changed without departing from the spirit of the present invention. Etc. may be changed and implemented.

[0013]

[Effect of device]

 As described above in detail, in the present invention, since air is stored in the air chamber, continuous breathing is possible even if the water surface is a little rough, and further, a waterproof cap and an air hole on the air chamber are provided. And the arrangement of the air intake section prevents water from entering the inside of the pipe, so it is not necessary to blow out the water that entered the pipe, and therefore the user of this device floats up near the water surface for breathing. It is not necessary and has the excellent effect of being very easy to breathe.
