Abstract
The invention relates to sports equipment, in particular to a narrow-mouth type water-inflow-prevention floating and diving breathing tube head which is simple and small in structure, can prevent a user from being choked by waves when floating and diving and is based on a reverse two-stage air inlet channel, and 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
Technical Field
The invention relates to sports equipment, in particular to a narrow-mouth type water-inflow-prevention floating and diving breathing tube head which is simple and small in structure, can prevent a user from being choked by waves when floating and diving and is based on a reverse two-stage air inlet channel.
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 purpose of the invention is:
aiming at the problems in the prior art, the invention provides the narrow-mouth type water inflow prevention floating and diving breathing tube head which is simple and small in structure, can prevent a user from being choked by waves when floating and diving and is based on a two-stage air inlet channel.
The scheme adopted by the invention is as follows:
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.
The invention is installed at the outlet of the snorkel by the installation head. 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.
Thus, the present invention can reduce the adverse effects of waves on a diver.
The invention has the beneficial effects that:
1, reducing the adverse effect of waves on a diver. 2, simple structure, easy to use.
The industrial possibility of the invention is:
the invention provides a narrow mouth type anti-water-inflow floating and diving breathing tube head based on a reverse two-stage air inlet channel, which can prevent a user from being choked by waves when floating and diving for common residents. Therefore, the invention has the possibility of industrial production.

Detailed Description
The following are specific embodiments of the present invention, and the embodiments of the present invention will be further described with reference to the drawings, but the present invention is not limited to these embodiments.
The narrow-mouth type anti-water-inflow floating and diving breathing tube head consists of the following parts:
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.
The invention is installed at the outlet of the snorkel by the installation head 3. 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 by way of specific embodiments, but those skilled in the art will appreciate that various modifications and variations can be made within the spirit and scope of the invention as hereinafter claimed.
