Abstract

The invention relates to sports equipment, in particular to a narrow-mouth type anti-water-inflow floating and diving breathing tube head based on a reverse two-stage air inlet channel, which comprises the following parts: the lower part of the outer cover is a narrow cover opening, and the upper part of the outer cover is a wide cover body to form a first-stage air inlet channel; the air pipe extends into the outer cover from the narrow cover opening and is arranged in the outer cover through the mounting frame to form a second-stage air inlet channel with opposite air flow directions; the lower end of the breather pipe is provided with an installation head; the upper end of the breather pipe is close to the inner top of the outer cover; the broad cover body is provided with a small amount of small holes, and the height of the small holes is slightly lower than the upper end of the vent pipe.

Description

Narrow-mouth type anti-water-inflow floating and diving breathing tube head based on reverse two-stage air inlet channel

Technical Field

The utility model relates to a sport equipment particularly, relates to a simple structure is small and exquisite, can avoid the user to be choked water by the wave when floating and submerging, prevents into water and floats and submerge breathing tube head based on a narrow mouth formula of reverse second grade intake duct.

Background

Floating and diving is not only an exercise but also a relaxation, and is a leisure choice for people of all ages. However, in both artificial swimming pools and natural bathing spots, the waves often hit the entrance of the snorkel tube of the diver, causing the diver to choke water, which affects his health and mood.

The existing products and technologies are difficult to provide a floating and diving breathing tube head which has a simple and small structure and can prevent a user from being choked by waves when floating and diving.

Disclosure of Invention

The utility model aims at:

the utility model discloses exist to current technique the problem provides a simple structure is small and exquisite, can avoid the user to be choked water by the wave when floating and submerging, prevents into water and floats and submerge breathing tube head based on a narrow mouth formula of second grade intake duct.

The utility model adopts the scheme that:

the narrow-mouth type anti-water-inflow floating and diving breathing tube head consists of the following parts:

the lower part of the outer cover is a narrow cover opening, and the upper part of the outer cover is a wide cover body to form a first-stage air inlet channel; the air pipe extends into the outer cover from the narrow cover opening and is arranged in the outer cover through the mounting frame to form a second-stage air inlet channel with opposite air flow directions; the lower end of the breather pipe is provided with an installation head; the upper end of the breather pipe is close to the inner top of the outer cover; the broad cover body is provided with a small amount of small holes, and the height of the small holes is slightly lower than the upper end of the vent pipe.

Will through the installation head the utility model discloses install in the exit of snorkel. When the narrow-mouth type water-floating-submergence-preventing breathing tube head is suddenly immersed by waves, water cannot suddenly enter the narrow cover mouth or the small hole in a large quantity, and only can enter some water to the bottom of the wide cover body due to the fact that people inhale the water. This water does not submerge the pores and does not enter the person's respiratory system through the upper end of the snorkel. If the wave continuously submerges the narrow mouth type anti-water-intake snorkel head for a period of time, the broad body can temporarily provide air for the snorkel. After the waves pass, the water entering the outer cover can gradually flow out through the narrow cover opening. In the process of water leakage, the small holes play a role in pressure relief.

Therefore, the utility model discloses can reduce the wave to the adverse effect of snorkeling person.

The utility model has the advantages that:

1, reducing the adverse effect of waves on a diver. 2, simple structure, easy to use.

The utility model discloses an industry is probably:

the utility model discloses a common resident provides one kind and can avoid the user to chock by the wave when floating and submerging and submerge the breathing tube head based on a narrow mouth formula of preventing that reverse second grade intake duct from intaking, and this narrow mouth formula is prevented that it is simple to intake to float and submerge the breathing tube head structure, easy to use and production. Therefore, the utility model has the possibility of industrial production.

In the figure: 1, an outer cover; 11, a wide cover body; 12, a small hole; 13, narrow cover openings; 14, a mounting frame; 2, a breather pipe; and 3, mounting the head.

Detailed Description

The following are embodiments of the present invention, and the aspects of the present invention will be further described with reference to the drawings, but the present invention is not limited to these embodiments.

the device comprises a housing 1, wherein the lower part of the housing 1 is a narrow housing opening 13, and the upper part of the housing 1 is a wide housing body 11; a vent pipe 2 extending into the housing from a narrow housing opening 13 and mounted in the housing 1 by means of a mounting bracket 14; the lower end of the breather pipe 2 is provided with an installation head 3; the upper end of the breather pipe 2 is close to the inner top of the outer cover 1; the broad cover body 11 is provided with a small number of small holes 12, and the height of the small holes 12 is slightly lower than the upper end of the vent pipe 2.

Will through installation head 3 the utility model discloses install in the exit of snorkel. When the narrow mouth type water-floating-submergence preventing breathing tube head is suddenly immersed by waves, water cannot suddenly enter the narrow cover mouth 13 or the small hole 12 in a large amount, and only some water can enter the bottom of the wide cover body 11 due to the inspiration of people. This water does not submerge the aperture 12 and enter the person's respiratory system through the upper end of the snorkel 2. If the wave continues to submerge the narrow mouth snorkel head for a period of time, the canopy body 11 can temporarily provide air to the snorkel. After the wave, the water entering the housing 1 will gradually flow out through the narrow housing mouth 13. In the process of water leakage, the small holes 12 play a role in pressure relief.

In the above description, the present invention has been described with reference to specific embodiments, but those skilled in the art will understand that various modifications and changes can be made within the spirit and scope of the present invention without departing from the scope of the claims.
