Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 8 The present invention provides a fully inflatable neck-mounted life jacket, comprising an airbag 1, a reflective strip 2, an air cylinder 3, a pull rope 4, a controller 5, a strap buckle 6, a valve rod 7, a push tube 8, a first spring 9, a limit rod 10, a threading pipe 11, a water immersion sensor 12, a second spring 13, a third spring 14, a vent valve 15, a fourth spring 16, a magnetic block 17, and a vent hole 18. The airbag 1 is equipped with reflective strips 2, an air cylinder 3, a pull rope 4, and a controller 5 on its side. The airbag 1 is U-shaped overall, and reflective strips 2 are fixedly connected to both the upper and lower surfaces of the airbag 1. The airbag 1 is divided into two independent chambers, left and right. This U-shaped design better conforms to the curve of the human neck, allowing it to be hung more comfortably around the neck during use. The reflective strips 2, fixedly connected to both the upper and lower surfaces of the airbag 1, reflect light in low-light environments, making it easier for rescuers to quickly locate the person in the water and improving rescue efficiency. The airbag 1 is divided into two independent chambers, left and right. This design ensures that even if one chamber is damaged, the other chamber can still maintain a certain buoyancy, increasing the safety and reliability of the life jacket. The air cylinder 3 is equipped with a valve stem 7 and a fourth spring 16 on its side. The controller 5 is fixedly connected to the side of the airbag 1. The controller 5 is threaded to the air cylinder 3 at the center of its left side, and the pull rope 4 is fixedly connected to the right side of the controller 5. This connection method facilitates the installation and removal of the air cylinder 3, making it convenient to replace or maintain the air cylinder 3. Furthermore, the controller 5 is fixedly connected to the right side of the pull rope 4, which provides a way to manually start the inflation of the life jacket. The controller 5 is equipped with a push tube 8, a first spring 9, a limit rod 10, a threading pipe 11, and a water immersion sensor 12 on its side. The opening position on the side of the gas cylinder 3 is set with an external thread, and the valve rod 7 is slidably connected to the opening position on the right side of the gas cylinder 3. The fourth spring 16 is installed on the side of the valve rod 7. The opening position on the side of the gas cylinder 3 is set with an external thread, and the valve rod 7 is slidably connected to the opening position on the right side of the gas cylinder 3. The fourth spring 16 is installed on the side of the valve rod 7. The external thread design works with the valve stem 7 and the fourth spring 16. Under normal conditions, the fourth spring 16 presses the valve stem 7 to prevent gas leakage. When gas needs to be filled, external force can move the valve stem 7 to open the gas cylinder 3 and release the gas. A third spring 14 is installed above the limit rod 10. A water immersion sensor 12 is embedded in the center of the right side of the controller 5. The water immersion sensor 12 has a built-in power supply and is connected to the magnetic block 17. The water immersion sensor 12 can monitor in real time whether the life jacket is in contact with water. Once water is detected, the built-in power supply powers the life jacket, which sends a signal to the magnetic block 17, thereby triggering the subsequent inflation action and realizing the automatic inflation function. A vent valve 15 is installed below the limit rod 10. The limit rod 10 is rotatably connected above the center line of the controller 5. The third spring 14 is fixedly connected to the upper right side of the limit rod 10, and a pull rope 4 is installed on the right side of the limit rod 10. The pull rope 4 passes through the cable conduit 11. The limit rod 10 is rotatably connected above the center line of the controller 5. The third spring 14 is fixedly connected to the upper right side of the limit rod 10, and a pull rope 4 is installed on the right side of the limit rod 10. The pull rope 4 passes through the cable conduit 11.The third spring 14 provides a certain elastic force to the limiting rod 10, keeping the limiting rod 10 in a specific position under normal conditions. The pull rope 4 passes through the wire conduit 11 to avoid problems such as tangling during pulling. The side of the vent valve 15 is provided with a magnetic block 17, a vent hole 18 and the third spring 14. The first spring 9 is installed above the push tube 8. The vent valve 15 is engaged with the lower part of the limiting rod 10. The vent hole 18 is provided below the vent valve 15. The second spring 13 is fixedly connected to the right side of the vent hole 18. The side of the vent valve 15 is provided with a guide strip and an airbag 1. The inner wall is slidably connected. The left side of the vent valve 15 push tube 8 is slidably connected to the airbag 1. The push tube 8 is fixedly connected to the fourth spring 16. The top of the push tube 8 is fixedly connected to the first spring 9. The lower part of the limit rod 10 is engaged with the vent valve 15. A vent hole 18 is provided below the vent valve 15. The right side of the vent hole 18 is fixedly connected to the second spring 13. A guide strip is provided on the side of the vent valve 15 and slidably connected to the inner wall of the airbag 1. The left side of the vent valve 15 push tube 8 is slidably connected to the airbag 1. The push tube 8 is fixedly connected to the fourth spring 16. The top of the push tube 8 is fixedly connected to the first spring 9. When the water immersion sensor 12 is triggered or the pull rope 4 is manually pulled, the limit rod 10 rotates, releasing the restriction on the vent valve 15. Under the action of the spring, the push tube 8 moves, opening the vent valve 15, allowing the gas in the gas cylinder 3 to enter the airbag 1 through the vent hole 18, thus achieving inflation.

[0017] Working principle: When using an automatic inflatable neck-hanging life jacket, first put the life jacket on your neck through the strap buckle 6 and adjust it to a suitable position.

[0018] When a user accidentally falls into the water, the water immersion sensor 12 comes into contact with the water, activating its built-in power supply and sending a signal to the magnetic block 17. Affected by the signal, the magnetic force between the magnetic block 17 and the vent valve 15 changes, causing the vent valve 15 to move under the action of the second spring 13 and the fourth spring 16. Simultaneously, the limiting rod 10 rotates under the elastic force of the third spring 14, releasing the locking restriction on the vent valve 15. At this time, the high-pressure gas in the gas cylinder 3 quickly enters the air bladder 1 through the vent 18, causing the air bladder 1 to rapidly inflate and provide buoyancy for the user.

[0019] If the user realizes the danger before falling into the water, they can manually pull the pull rope 4. Pulling the rope 4 will cause the limit rod 10 to rotate, which will also release the restriction on the air valve 15, thereby realizing the inflation process of the airbag 1.

[0020] During inflation, the guide strip on the side of the vent valve 15 slides against the inner wall of the airbag 1, ensuring the stability of the movement of the vent valve 15. The sliding connection between the push tube 8 and the airbag 1 also facilitates the smooth transmission of gas. Once the airbag 1 is fully inflated, the user can float on the water surface and wait for rescue using the buoyancy of the airbag 1. During this time, the reflective strip 2 can help rescuers quickly spot the target.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
