Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of life-saving protective equipment, and in particular relates to a helmet that can prevent mouth and nose from being choked by sea waves. Background Art
[0002] Wearing a waterproof life jacket is undoubtedly an important guarantee for safety during water activities or operations, but it cannot completely eliminate all risks. On the rough sea, the impact of waves cannot be underestimated. When people who fall into the water lower their heads, turn their faces, shout, or talk, water can easily rush into their mouths and noses, causing choking and coughing. Therefore, people who fall into the water should pay attention to adjusting their body posture to avoid this as much as possible. When a ship is in a shipwreck or a naval vessel is hit and people on board fall into the water, the time to wait for rescue forces is relatively long or even very long. If the people who fall into the water suffer trauma during the shipwreck or battle and their limbs are restricted in movement, it is more likely that seawater will enter the respiratory tract and cause choking and coughing. At present, some rescue helmets in waters are heavy. Although they are helpful in reducing the impact on the head, they cannot protect the user's mouth and nose well, and it is still easy to cause choking by seawater. Moreover, under the impact of waves, the position of the head and face is forced to change and sink underwater, which is also easy to cause choking by seawater. Summary of the invention
[0003] The technical problem to be solved by the present invention is to provide a helmet for preventing mouth and nose from being choked by sea waves, so as to maintain the position and angle of the user's head, thereby effectively avoiding choking of the nose by sea water.
[0004] In order to solve the above problems, the present invention adopts the following technical solutions:
[0005] A helmet for preventing mouth and nose from being choked by sea waves comprises a helmet body which accommodates the entire head, an elastic neckband which surrounds the neck is arranged at the lower end of the helmet body, an inflatable air bag is arranged on the rear side of the helmet body, an air hole which is opened downward at the chin part of the helmet body, a water retaining part is arranged at the lower end of the air hole, an air flow groove for circulating gas is arranged between the water retaining part and the air hole, and a drainage groove which is connected with the air flow groove is arranged on the water retaining part.
[0006] Furthermore, the drainage grooves are staggered with the air holes, so that the wearer's breathing is not affected during drainage.
[0007] Furthermore, the drainage groove is opened downward from the bottom of the airflow groove and passes through to the outside of the water retaining part, which is conducive to the water entering the airflow groove to be discharged from the drainage groove.
[0008] Furthermore, the helmet body is made of silicone material, which is relatively soft and easy to fold and placed in a small container. Naval soldiers can even hang it around their waists in combat environments like carrying a gas mask, and the silicone material is more comfortable to wear.
[0009] Furthermore, a protective shell is provided on the top of the helmet body to increase strength, which is beneficial for protecting the top of the head, avoiding direct sunlight, and minimizing body temperature loss when the sea water temperature is low.
[0010] Furthermore, the eyes of the helmet body are provided with a transparent protective sheet, which is sealed and connected to the helmet body, making it convenient to observe the outside.
[0011] Furthermore, an inner waterproof layer and an outer waterproof layer are provided on the side of the helmet body. The inner waterproof layer is provided with a plurality of first sound listening holes at the ear, and the outer waterproof layer is provided with a plurality of second sound listening holes at the ear. The positions of the first sound listening holes and the second sound listening holes are staggered. A drainage hole is provided on the outer waterproof layer, and the drainage hole is located below the second sound listening hole, which is convenient for listening to external sounds and preventing waves from hitting the ears, thereby preventing water from entering the ears.
[0012] Furthermore, a longitudinal waterproof zipper is provided on the rear side of the helmet body, which is convenient for wearing and can prevent water from entering the helmet body.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The present invention arranges an air bag on the rear side of the helmet body and uses the buoyancy of the air bag to lift the head, which is helpful to maintain the position and angle of the wearer's head and keep the head above water. At the same time, the air holes are also located on the water surface for easy breathing.
[0015] 2. The present invention provides a water retaining portion at the lower end of the air hole to block the rising waves, so that the waves are not easy to enter the air hole, thereby preventing the wearer from choking. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0020] like Figure 1 and Figure 2 As shown, the anti-wave choking helmet of this embodiment includes a helmet body 1 that accommodates the entire head. The helmet body 1 is made of silicone material, is comfortable to wear, and is easy to fold and store. An elastic neckband 6 that surrounds the neck is provided at the lower end of the helmet body 1, which can fit the neck and reduce the gap between the neck, thereby facilitating the reduction of water entering the helmet body 1. The helmet body 1 is provided with an inflatable airbag 4 on the rear side, which can provide an upward supporting force for the head in water. At the same time, the helmet body 1 has an air hole 7 opened downward at the chin, and the air hole 7 includes a plurality of holes connected to the outside for breathing. The lower end of the air hole 7 is provided with a water retaining part 9, and an air flow groove 8 for circulating gas is provided between the water retaining part 9 and the air hole 7. The water retaining part 9 is provided with a drainage groove 10 connected with the air flow groove 8. When the airbag 4 is supported at the back of the head, the head and face face upward, so that the air hole 7 and the water retaining part 9 are above the water surface. When waves rise, the water retaining part 9 can block seawater to prevent the waves from directly impacting the air hole 7 and causing choking. The water entering the air flow groove 8 from the side can be discharged through the drainage groove 10.
[0021] The drainage groove 10 is staggered with the air hole 7 . The drainage groove 10 is opened downward from the bottom of the air flow groove 8 and passes through to the outside of the water retaining part 9 . This is conducive to the water entering the air flow groove 8 to be discharged from the drainage groove 10 and avoid entering the air hole 7 .
[0022] In addition, a protective shell 2 for increasing strength is provided on the top of the helmet body 1, such as glass fiber reinforced plastic, which is glued and fixed to the top of the helmet body 1 and has strong impact resistance to protect the head. At the same time, the protective shell 2 is provided with a fluorescent layer to improve visibility during rescue under low light conditions.
[0023] A transparent protective sheet 3 is provided at the eye portion of the helmet body 1 , and the protective sheet 3 is sealedly connected to the helmet body 1 , so that the wearer can observe the outside.
[0024] An inner waterproof layer 11 and an outer waterproof layer 12 are provided on the side of the helmet body 1. The inner waterproof layer 11 has several first sound holes 13 at the ear, and the outer waterproof layer 12 has several second sound holes 14 at the ear. The positions of the first sound holes 13 and the second sound holes 14 are staggered. A drainage hole 15 is provided on the outer waterproof layer 12, and the drainage hole 15 is located below the second sound hole 14. Water enters from the second sound hole 14, but it is difficult to pass through the first sound hole 13 and impact the ear. Water entering between the first sound hole 13 and the second sound hole 14 will flow out from the drainage hole 15. The provision of the first sound hole 13 and the second sound hole 14 is also beneficial to increasing the internal and external air permeability of the helmet body 1.
[0025] A longitudinal waterproof zipper 5 is provided on the rear side of the helmet body 1, which is convenient for opening and wearing on the head.
[0026] The present invention is used in conjunction with wearing a life jacket. After wearing the helmet body 1, the impact of waves on the head can be reduced. At the same time, an air bag 4 is arranged on the rear side of the helmet body 1 to lift the head to prevent the head from sinking and keep the face facing upward, which is conducive to maintaining the position and angle of the head, so that the air hole 7 and the water retaining part 9 are both located above the water surface, which is convenient for breathing. The water retaining part 9 can block the waves impacting the water surface and prevent them from entering from the air hole 7, thereby helping to avoid choking.
[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
