Description

Technical Field

[0001] The utility model relates to the technical field of life jacket inflation, in particular to an automatic inflation device for a life jacket after falling into water. Background Art

[0002] A life jacket is a piece of safety equipment used for water activities or to deal with dangerous situations in the water. It is usually made of lightweight, waterproof materials and filled with materials that can provide buoyancy, such as foam plastics or air bags. There are two common types of life jackets: one is a floating collar type that hangs around the neck, and the other is a waist type that is tied at the waist. The floating collar life jacket keeps the head above the water by providing buoyancy around the neck, allowing the user to move freely and keep the head from being submerged in water; while the waist-type life jacket keeps the body floating on the water by providing buoyancy at the waist. Regardless of the type, life jackets are essential equipment for water activities, providing critical safety protection, reducing the risk of drowning, and ensuring that the user can stay above the water and wait for rescue in an emergency.

[0003] Currently, inflatable life jackets are mainly divided into two types: manual inflation and automatic inflation. Automatic inflation life jacket inflation equipment usually uses a soluble barrier sheet to prevent gas release, which will quickly dissolve once it comes into contact with water and activate the inflation mechanism. However, some water-soluble sheets may react slowly after coming into contact with water, or have poor water solubility, resulting in insufficient inflation speed, which may delay rescue time. In order to cope with this situation, life jackets are usually designed with a manual puncture device, and the user can manually trigger the inflation process by pulling the rope. However, this type of pull rope also has certain risks, because long-term storage or external environmental factors may cause the pull rope to age and damage, or even break during use, affecting the effect of manual puncture.

[0012] Multiple triggering mechanisms: The device uses three triggering methods: manual puncture structure, water-soluble protrusion puncture structure and electric protrusion puncture structure. This multiple triggering mechanism increases the reliability and flexibility of the device in triggering under different circumstances.

[0013] High safety: By adopting multiple triggering methods, the device is more flexible in responding to triggering requirements in different situations, improving the safety of responding to emergencies. Whether it is triggered manually by the user, water dissolution or electrical signal, it can puncture the gas cylinder seal in time to achieve rapid inflation.

[0014] Avoid the influence of component aging: Since the device uses multiple triggering methods, even if one of them fails to work properly due to component aging, other triggering methods can still be competent to puncture the gas cylinder seal, thus avoiding the influence of component aging that may occur in a single trigger mechanism. This design greatly improves the reliability and durability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Specific implementation mode of the utility model: When the utility model is in use, the air outlet 9 is fixed to the air inlet of the life jacket and sealed, and the gas tank 2 containing compressed carbon dioxide is screwed on the connecting pipe 3. At this time, the life jacket is stored in the storage sleeve. When encountering danger and needing to jump into the water, if time and situation permit, the blocking tape 22 is torn off, and the plastic safety rod 20 is pulled out upward, so that the rotating rod 11 is in a rotatable state, and the rotating knob 13 on the rotating rod 11 is grasped and twisted toward the body to rotate the rotating rod 11, so that the gear 12 meshes with the gear 12, so that the guide bar 16 slides in the guide groove 15, so that the puncture knife 7 on the left side moves forward, and the sliding plug 6 slides forward in the cylinder 5, so that the puncture knife 7 pierces the seal of the gas tank 2, so that the internal compressed carbon dioxide quickly overflows and quickly fills the entire life jacket from the air outlet 9, and then jumps into the water and waits for rescue.

[0027] If time and actual conditions do not allow active rotation of the rotating knob 13, or the user loses consciousness and falls into the water, water will enter the water inlet hole 8 on the puncture box 1, causing the water-soluble substance to dissolve in water, and the spring 25 will no longer be blocked, and the sliding sheet 24 will slide in the elastic box 23. The spring 25 will quickly pop out the pop-up rod 26, causing the middle puncture knife 7 to move forward and puncture the seal of the inflatable tank 2, thereby quickly inflating the life jacket and floating the user on the water surface to wait for rescue; at the same time, water will enter the perforated hollow box 30, and after the water immersion sensor 31 senses the water, it will send an electrical signal to the power storage control box 29, causing the waterproof micro-electric push rod 28 to extend, causing the puncture knife 7 on the right to puncture the seal of the inflatable tank 2, quickly inflating the life jacket, and waiting for rescue.

[0028] The above three puncture methods are implemented independently, and no matter which method is used, the life jacket can be quickly inflated. Even if the water-soluble sheet 27 dissolves slowly, the inflation speed will not be delayed. Moreover, no matter which of the three methods takes effect first, the latter two will not damage the inflation effect.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
