Description

Technical Field

[0001] This utility model relates to backpacks, and more particularly to a self-rescue backpack for drowning. Background Technology

[0002] With the diversification of outdoor activities and commuting scenarios, backpacks have become an indispensable tool in people's daily lives. However, in water-related scenarios (such as ferries, bridge walking, and coastal travel) or accidental falls into water, ordinary backpacks can only provide limited buoyancy assistance and may even increase the burden due to water ingress, endangering the user's safety.

[0003] To address drowning situations, existing backpacks are equipped with airbags. However, if the airbag is too large, it will take up too much backpack space, making it impossible to wear the backpack properly or store items. If the airbag is too small, the buoyancy it provides will be limited and it will not be able to support the drowning person to move in the water.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] This invention provides a self-rescue backpack for drowning, which solves the technical problem that existing backpacks cannot provide sufficient buoyancy.

[0006] This utility model provides a self-rescue backpack for drowning, including a backpack body and a self-rescue device. The backpack body forms a cavity, and the self-rescue device includes: an airbag disposed in the cavity; an air tank disposed in the cavity and controlled to be connected to the airbag; and a control component disposed on the pipe connecting the airbag and the air tank, with the control end of the control component located outside the cavity. The air tank stores high-pressure gas, and the control component is configured to connect the air tank and the airbag when the control end is pulled, so as to inflate the airbag.

[0007] In this design, a pre-stored high-pressure gas tank is directly connected to the airbag. The airbag inflates within 0.5 to 2 seconds after the control component is activated, rapidly generating buoyancy (the specific value depends on the airbag volume and pressure) to effectively counteract the body's weight and prevent drowning. The airbag, gas tank, and control component are all integrated into the backpack's cavity, taking up no extra space. The backpack can still normally store clothing, tools, and other everyday items, balancing practicality and concealment. The control terminal requires only a single pull to activate the air circuit, requiring no electricity, complex procedures, or strength. It can be reliably operated even by children, those with limited physical strength, or in a state of panic. The gas tank allows the airbag to inflate quickly, providing sufficient buoyancy to the drowning victim through the backpack, ensuring their ability to move in the water.

[0008] In a further embodiment of this utility model, the control component includes: a valve disposed on the pipe connecting the airbag and the air tank to control the connection between the airbag and the air tank; and a rope, one end of which is wrapped around the valve and the other end of which passes through the backpack body and is disposed outside the cavity, so that the valve is opened when the rope is pulled.

[0009] In a further embodiment of this utility model, the backpack body is provided with a through hole, and the rope passes through the backpack body through the through hole; the control component also includes a pull ring, which is connected to the end of the rope located outside the cavity and has a diameter larger than the through hole.

[0010] In a further embodiment of this invention, the gas storage tank is filled with a protective gas, and the volume of the inflated airbag is greater than 18 liters.

[0011] In a further embodiment of this utility model, the backpack body includes: a bag body forming a cavity; a pair of shoulder straps disposed on the bag body for wear by a user; and a divider disposed within the cavity and dividing the cavity into a storage cavity and a self-rescue cavity, wherein the airbag and the air tank are disposed within the self-rescue cavity, and the storage cavity is used to store items.

[0012] In a further embodiment of this utility model, the self-rescue backpack for drowning also includes a buoyancy wristband, which is attached to the shoulder strap via Velcro or by a soft rope.

[0013] In a further embodiment of this utility model, a pair of waist belts protrude from both sides of the bottom end of the bag body, and the pair of waist belts are detachably connected by buckles.

[0014] This invention utilizes a pre-stored high-pressure gas tank directly connected to the airbag. The airbag inflates within 0.5-2 seconds after the control component is activated, rapidly generating buoyancy (the specific value depends on the airbag volume and pressure) to effectively counteract body weight and prevent drowning. The airbag, gas tank, and control component are all integrated into the backpack cavity, occupying no extra space. The backpack can still normally store clothing, tools, and other daily necessities, balancing practicality and concealment. The control terminal requires only a single pull to activate the air circuit, requiring no electricity, complex procedures, or strength. It can be reliably operated even by children, those with insufficient physical strength, or in a state of panic. The gas tank allows the airbag to inflate rapidly, providing sufficient buoyancy to the drowning victim through the backpack, ensuring their ability to move in the water.

[0028] Please refer to Figures 1-2This utility model provides a self-rescue backpack for drowning, including a backpack body 100 and a self-rescue device 200. The backpack body 100 forms a cavity 100A. The self-rescue device 200 includes: an airbag 230 disposed within the cavity 100A; an air tank 220 disposed within the cavity 100A and controlled to be connected to the airbag 230; and a control component 210 disposed on the pipe connecting the airbag 230 and the air tank 220, with the control end of the control component 210 located outside the cavity 100A. The air tank 220 stores high-pressure gas, and the control component 210 is configured to connect the air tank 220 and the airbag 230 when the control end is pulled, so that the airbag 230 is inflated.

[0029] In this design, a pre-stored high-pressure gas tank 220 is directly connected to the airbag 230. The airbag 230 inflates within 0.5 to 2 seconds after the control component 210 is triggered, rapidly generating buoyancy (the specific value depends on the volume and pressure of the airbag 230), effectively offsetting the body weight and preventing drowning. The airbag 230, gas tank 220, and control component 210 are all integrated into the backpack cavity 100A, occupying no extra space. The backpack can still normally store clothing, tools, and other daily necessities, balancing practicality and concealment. The control terminal requires only a single pull to trigger the air circuit connection, requiring no electricity, complex procedures, or strength, and can be reliably operated even by children, those with insufficient physical strength, or in a state of panic. The gas tank 220 allows the airbag 230 to inflate quickly, providing sufficient buoyancy to the drowning victim through the backpack, ensuring their movement in the water.

[0030] In a further embodiment of this utility model, the control component 210 includes: a valve 213, disposed on the pipe connecting the airbag 230 and the air tank 220, to control the connection between the airbag 230 and the air tank 220; and a rope 212, one end of which is wrapped around the valve 213, and the other end of which passes through the backpack body 100 and is disposed outside the cavity 100A, so that the valve 213 is opened when the rope 212 is pulled.

[0031] In this design, a pre-stored high-pressure gas tank 220 is directly connected to the airbag 230. After the control component 210 is triggered, the airbag 230 inflates within 0.5 to 2 seconds, instantly generating sufficient buoyancy to ensure the drowning victim's head quickly floats to the surface, avoiding the risk of choking. The single-pull trigger mechanism uses a rope 212 to pull the mechanical valve 213, requiring no electricity, complex procedures, or strength. It can be reliably triggered even by children, those with insufficient physical strength, or in a state of panic.

[0032] Furthermore, the rope 212 needs to be designed with a margin, meaning that the valve 213 needs to be opened after the end of the rope 212 is pulled continuously for 2cm, to prevent accidental activation during daily carrying.

[0033] In a further embodiment of this utility model, the backpack body 100 is provided with a through hole 100B, and the rope 212 passes through the backpack body 100 through the through hole 100B; the control component 210 also includes a pull ring 211, which is connected to the end of the rope 212 located outside the cavity 100A and has a diameter larger than the through hole 100B.

[0034] The through hole 100B and the rope body 212 are fitted with a clearance to ensure that the rope body 212 moves in a straight line along the axis when pulled, avoiding entanglement or deviation. The diameter of the pull ring 211 is larger than the diameter of the through hole 100B, and a pulling force of ≥5N is required to start it. This can prevent accidental triggering caused by daily friction or snagging, and ensure that it can be quickly identified and operated in an emergency. The rope body 212 can be made of nylon rope with a diameter of 3mm, and the diameter of the through hole 100B is generally set to 8mm.

[0035] In a further embodiment of this utility model, the gas storage tank 220 is filled with protective gas, and the inflated volume of the airbag 230 is greater than 18 liters.

[0036] The gas tank 220 is filled with high-purity nitrogen, carbon dioxide, or argon as a protective gas to prevent oxygen and water vapor from reacting with the material of the airbag 230 (TPU-coated nylon), thus extending the material's lifespan by 3 times. Based on Archimedes' principle, the 18L airbag 230 can provide ≥18kg of buoyancy, fully covering the head of an average adult to float above the water. The remaining buoyancy can support personal items (such as clothing that becomes heavier when soaked in water). The average adult weight is 70kg.

[0037] In a further embodiment of this utility model, the backpack body 100 includes: a bag body 110 forming a cavity 100A; a pair of shoulder straps 130 disposed on the bag body 110 for wear by a user; and a divider 120 disposed within the cavity 100A and dividing the cavity 100A into a storage cavity 100A1 and a self-rescue cavity 100A2, wherein the airbag 230 and the air tank 220 are disposed within the self-rescue cavity 100A2, and the storage cavity 100A1 is used to store items.

[0038] In this design, a separator 120 separates the airbag 230 from the air tank 220 to prevent damage to the air circuit caused by squeezing or scratching of stored items, ensuring that the self-rescue device 200 will not be damaged due to normal use of the backpack. The storage cavity 100A1 can retain independent space, and sensitive items such as electronic devices and documents can be safely stored through the built-in waterproof partition to prevent water damage to the items in the event of falling into the water.

[0039] Furthermore, the seams of the bag body 110 are all sealed with PE adhesive strips by heat pressing to ensure overall airtightness and increase buoyancy for self-rescue in the water.

[0040] In a further embodiment of this invention, the self-rescue backpack also includes a buoyancy wristband 300, which is attached to the shoulder strap 130 via Velcro or a soft cord. The buoyancy wristband 300, connected to the shoulder strap 130 via Velcro or a soft cord, serves as a backup buoyancy source in case the airbag 230 fails.

[0041] In a further embodiment of this invention, a pair of waist belts 140 protrude from both sides of the bottom end of the bag body 110, and the pair of waist belts 140 are detachably connected by buckles. The waist belts 140 can be made of memory foam and quick-drying fabric, and are fixed to the hips by buckles, distributing the weight of the backpack to the waist, reducing the load on the shoulder straps 130, and preventing the backpack from coming off due to water impact when it falls into water.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
