Problems solved by technology

[0006] No matter what kind of schoolbag or backpack disclosed above, although the user falls into the water, the water will produce a greater buoyancy to the schoolbag or backpack, but after the user falls into the water, it must generate buoyancy on the human body and the schoolbag or backpack to prevent drowning. Or the backpack must be attached to the user. Like this, when the water produces buoyancy to the schoolbag or backpack, under the effect of buoyancy, the face of the human body will inevitably move towards the water surface or in the water. Therefore, even if the human body is floated by the schoolbag or backpack Yes, but the face of the human body will be immersed in the water, which will also cause drowning

Abstract

The invention discloses a safety buoyancy knapsack and a self-rescue method by using the same. The safety buoyancy knapsack comprises a knapsack body, and a containing cavity is formed in the knapsackbody; a buoyancy device is arranged on the knapsack body, and a water inlet communicated with the containing cavity is formed in the knapsack body. The method comprises the steps that after a personcarrying the knapsack falls into water, the person floats under the action of the buoyancy device; water sequentially enters the containing cavity through the water inlet, the gravity of the knapsackis increased, the knapsack filled with the water generates backward turning force on the human body, and the head of the human body leaks out of the water surface. According to the safety buoyancy backpack and the self-rescue method, buoyancy is provided for the human body after the human body falls into water; meanwhile, the backpack is prevented from pressing the human body, and the safety performance is improved.

Description

technical field [0001] The invention relates to a safety buoyancy backpack and a self-rescue method using the safety buoyancy backpack. Background technique [0002] Backpacks or schoolbags do not have much buoyancy. If a user accidentally falls into the water while carrying a schoolbag or backpack, the schoolbag or backpack will not only fail to provide buoyancy, but will increase gravity, making the user more dangerous, and cannot provide rescue for the user when they encounter water while traveling effect. As a result, there are a lot of buoyancy packs out there now. [0003] For example, in the patent document with the Chinese patent application number 201920047793.0 and the authorized announcement date being 2019.11.26, an anti-drowning backpack is disclosed, which includes a bag body, a handle and two straps, and the handle is fixedly connected to the top of the bag body. , the strap includes a fixing part and an adjusting part, the fixing part and the adjusting part...
