Description

Technical Field

[0001] This utility model belongs to the technical field of lifesaving and protective equipment, specifically relating to a helmet that prevents sea waves from choking the mouth and nose. Background Technology

[0002] Wearing a waterproof life jacket is undoubtedly an important safety guarantee when engaging in water activities or operations, but it cannot completely eliminate all risks. On a rough sea, the impact of waves should not be underestimated. When a person falls into the water bends their head, turns their face, shouts, or talks, water can easily enter their mouth and nose, causing choking. Therefore, people in the water should pay attention to adjusting their body posture as much as possible to avoid this. When a ship is in distress or a naval vessel is attacked and its crew falls into the water, the waiting time for rescue forces can be long. If a person in the water has suffered external injuries during the distress or combat and their limb movement is restricted, they are more likely to experience seawater entering their respiratory tract and causing choking. Currently, some water rescue helmets are heavy, which helps reduce the impact on the head, but they do not adequately protect the user's mouth and nose, making it easy for seawater to enter the nose and mouth. Moreover, the impact of waves forces the head and face to change position and sink underwater, which can also easily lead to seawater entering the mouth and nose. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a helmet that prevents seawater from irritating the mouth and nose, so as to maintain the user's head position and angle, thereby effectively preventing seawater from irritating the nose and mouth.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A helmet for protecting the mouth and nose from sea waves includes a helmet body that covers the entire head, an elastic neckband that wraps around the neck at the lower end of the helmet body, an inflatable air bladder on the rear side of the helmet body, a downward-facing air hole at the chin area of ​​the helmet body, a water-blocking part at the lower end of the air hole, an airflow channel for gas passage between the water-blocking part and the air hole, and a drainage channel communicating with the airflow channel on the water-blocking part.

[0006] Furthermore, the drainage channels and air vents are staggered, so that drainage does not affect the wearer's breathing.

[0007] Furthermore, the drainage channel extends downwards from the bottom of the airflow channel and extends to the outside of the water-blocking part, which facilitates the drainage of water that enters the airflow channel.

[0008] Furthermore, the helmet itself is made of silicone material, which is relatively soft, easy to fold, and can be placed in a small container. In combat environments, naval soldiers can even wear it around their waist like a gas mask, and the silicone material is more comfortable to wear.

[0009] Furthermore, the top of the helmet is equipped with a protective shell to increase its strength, which helps protect the top of the head, avoid direct sunlight, and minimize body heat loss when the seawater temperature is low.

[0010] Furthermore, the helmet body has a transparent protective plate for the eyes, which is sealed to the helmet body for easy observation of the outside.

[0011] Furthermore, the helmet body has an inner waterproof layer and an outer waterproof layer on its side. The inner waterproof layer has several first hearing holes in the ear area, and the outer waterproof layer has several second hearing holes in the ear area. The positions of the first and second hearing holes are staggered. The outer waterproof layer has drainage holes located below the second hearing holes, which facilitates hearing external sounds and prevents waves from hitting the ears, thus preventing water from entering the ears.

[0012] Furthermore, a vertical waterproof zipper is provided on the rear side of the helmet body, which makes it easy to put on and prevents water from entering the helmet body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model sets an airbag on the rear side of the helmet body, and uses the buoyancy of the airbag to support the head, which helps to maintain the wearer's head position and angle, keeping the head on the water surface, while the air hole is also located on the water surface for easy breathing.

[0015] 2. This utility model provides a water-blocking part at the lower end of the air hole to block the rising waves, making it difficult for waves to enter the air hole and thus preventing the wearer from choking on the nose. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] like Figure 1 and Figure 2 As shown, the helmet for protecting the mouth and nose from sea waves in this embodiment includes a helmet body 1 that accommodates the entire head. The helmet body 1 is made of silicone material, making it comfortable to wear and easy to fold and store. An elastic neck warmer 6 is provided at the lower end of the helmet body 1 to fit snugly around the neck, reducing the gap between the helmet body 1 and the neck, thereby helping to reduce the amount of water entering the helmet body 1. The helmet body 1 has an inflatable airbag 4 on its rear side, which provides upward support for the head in water. The helmet body 1 also has downward-facing air holes 7 at the chin area. The air holes 7 include multiple ones that connect to the outside to facilitate breathing. The lower end of the air hole 7 is provided with a water-blocking part 9. There is an airflow channel 8 between the water-blocking part 9 and the air hole 7. The water-blocking part 9 is provided with a drainage channel 10 that communicates with the airflow channel 8. When the airbag 4 supports the back of the head, the head and face are facing upward. In this way, the air hole 7 and the water-blocking part 9 are above the water surface. When the waves rise, the water-blocking part 9 can block seawater from entering the air hole 7 and causing choking. Water that enters the airflow channel 8 from the side can be discharged through the drainage channel 10.

[0021] The drainage channel 10 is offset from the air hole 7. The drainage channel 10 is opened downward from the bottom of the airflow channel 8 and extends to the outside of the water-blocking part 9. This facilitates the drainage of water entering the airflow channel 8 from the drainage channel 10 and prevents it from entering the air hole 7.

[0022] In addition, a protective shell 2 with increased strength is provided on the top of the helmet body 1. For example, it is made of glass fiber reinforced plastic and is glued and fixed to the top of the helmet body 1. It 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 in low light conditions.

[0023] A transparent protective plate 3 is provided in the eye area of ​​the helmet body 1. The protective plate 3 is sealed to the helmet body 1 so that the wearer can see the outside.

[0024] The helmet body 1 has an inner waterproof layer 11 and an outer waterproof layer 12 on its side. The inner waterproof layer 11 has several first hearing holes 13 at the ears, and the outer waterproof layer 12 has several second hearing holes 14 at the ears. The positions of the first hearing holes 13 and the second hearing holes 14 are staggered. The outer waterproof layer 12 has drainage holes 15 located below the second hearing holes 14. Water enters through the second hearing holes 14, but it is difficult for it to pass through the first hearing holes 13 and impact the ears. Water that enters between the first hearing holes 13 and the second hearing holes 14 will flow out through the drainage holes 15. The first hearing holes 13 and the second hearing holes 14 also help to increase the ventilation of the helmet body 1.

[0025] A vertical waterproof zipper 5 is provided on the rear side of the helmet body 1 for easy opening and wearing on the head.

[0026] This invention is used in conjunction with a life jacket. After wearing the helmet body 1, the impact of waves on the head can be reduced. At the same time, an airbag 4 is provided on the rear side of the helmet body 1 to support the head and prevent it from sinking, keeping the face upward. This helps to maintain the position and angle of the head, so that the air vent 7 and the water-blocking part 9 are both above the water surface, which is convenient for breathing. The water-blocking part 9 can block the waves impacting the water surface and prevent them from entering through the air vent 7, thus helping to avoid choking.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
