[0025] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of this disclosure will be more comprehensive and complete, and will fully convey the concepts of the example embodiments to those skilled in the art. The accompanying drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. Identical reference numerals in the figures indicate identical or similar parts, and thus repeated descriptions thereof will be omitted.

[0026] In addition, the described features, structures or characteristics can be combined in any suitable manner in one or more example embodiments. In the following description, many specific details are provided to provide a full understanding of the example embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure can be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. can be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0027] Example 1

[0028] like Figure 1-Figure 7 A water life-saving backpack includes a backpack body 1, a connecting belt 2, and an air supply component 3.

[0029] The connecting strap 2 includes a shoulder strap 21 and a side strap 22. The shoulder strap 21 is a hollow structure and is filled with a folded and airless air bag. Both ends of the shoulder strap 21 are fixed to the back of the backpack body 1. The user can carry the backpack body 1 on the back through the shoulder strap 21. The surface of the shoulder strap 21 is provided with a passage slot for the air bag to pop out.

[0030] The two side straps 22 correspond to the user's two armpits. Both ends of the side straps 22 are fixed to the back of the backpack body 1. The side straps 22 are hollow structures filled with folded and airless air bags. The surface of the side straps 22 is provided with a passage slot for the air bags to pop out.

[0031] An air supply part 3 is provided inside the backpack body 1, specifically including an inert gas compression tank 31 and an air pump 32. The air pump 32 can be started manually or automatically. The inert gas compression tank 31 is connected to the air pump 32 and the folded air bag in sequence through a pipeline. When the air pump 32 is turned on, an inert gas, such as carbon dioxide gas, is pumped into the folded air bag. The continuous input of gas causes the air bag to expand and pass through the through slots opened on the surface of the shoulder strap 21 and the side strap 22. The air bag inflated from the shoulder strap 21 is U-shaped and surrounds the outside of the user's neck. The air bag inflated from the connecting strap 23 drags the user who falls into the water from the user's armpit, reducing the probability of separation between the air bag and the user.

[0032] Example 2

[0033] like Figures 1-8 A water life-saving backpack includes a backpack body 1, a connecting belt 2, and an air supply component 3.

[0034] The connecting strap 2 includes a shoulder strap 21 and a side strap 22. The shoulder strap 21 is a hollow structure and is filled with a folded and airless air bag. Both ends of the shoulder strap 21 are fixed to the back of the backpack body 1, and the user can carry the backpack body 1 on the back through the shoulder strap 21. The surface of the shoulder strap 21 is provided with a passage slot for the air bag to extend out.

[0035] The two side straps 22 correspond to the positions of the user's two armpits. One end of the side strap 22 is fixed to the backpack body 1, and the other end is adhered to the back of the backpack body 1 through Velcro. The side strap 22 has a hollow structure and is filled with a folded and airless airbag. Several slits are opened in the middle of the side strap 22, and the side strap 22 is made of elastic material as a whole.

[0036] The backpack body 1 is provided with an air supply part 3 inside, specifically including an inert gas compression tank 31 and an air pump 32. The air pump 32 can be started manually or electrically. The inert gas compression tank 31 is connected to the air pump 32 and the folded air bag in sequence through a pipeline. When the air pump 32 is turned on, the gas in the inert gas compression tank 31 is pumped into the folded air bag. The continuous input of gas causes the air bag to expand and pass through the passage groove opened on the surface of the shoulder strap 21. The air bag inflated from the shoulder strap 21 is U-shaped and surrounds the outside of the user's neck. After the air pump 32 pumps the gas in the inert gas compression tank 31 into the air bag located in the side strap 22, the inflated air bag will stretch the elastic side strap 22, and allow the side strap 22 to overcome the adhesive force of the Velcro and leave the backpack body 1, so that the inflated air bag can lift the user from the user's armpit.

[0037] On the basis of Example 1 and Example 2:

[0038] Preferably, the shoulder strap 21 can be designed as one, with both ends of the shoulder strap 21 fixed to the back of the backpack body 1 in a diagonal direction.

[0039] Preferably, the shoulder straps 21 are provided in pairs, and the two shoulder straps 21 are symmetrically fixed to the back of the backpack body 1 corresponding to the user's shoulders.

[0040] Preferably, the surface of the airbag located in the shoulder strap 21 is adhered with Velcro. When the U-shaped airbag is fully inflated and expanded, the airbags on both sides of the user's neck can be attached together by the Velcro, reducing the probability of the user's head detaching from the airbag.

[0041] Preferably, the two straps 21 are fixedly connected by a connecting strap 23, and a U-shaped passage slot is opened on the straps 21 and the connecting strap 23. The folded airbag is located in the straps 21 and the connecting strap 23. In this way, the airbag expands and pops out from the U-shaped passage slot, which can shorten the time it takes for the airbag to fully deploy, further improving the practicality of the life-saving backpack.

[0042] Preferably, blocking sheets are fixed on the sides of the two long sides of the passage slot, and the two blocking sheets are stacked to improve the protection of the airbag body folded inside the passage slot.

[0043] It can be known that the working principle of the manual air pump 32 is as follows: when the operator manually starts the air pump 32, the air pump 32 will open the valve leading to the inert gas compression tank 31, and establish a path from the inert gas compression tank 31 to the air bag through the pipeline to inject the gas in the inert gas compression tank 31 into the corresponding air bag.

[0044] The working principle of the automatic air pump 32 is as follows: the air pump 32 is controlled by a water flow sensor. Only when the water flow continues to act on the water flow sensor, the water flow sensor controls the air pump 32 through the controller to open, so as to inject the carbon dioxide gas in the inert gas compression tank 31 into the corresponding air bag.

[0045] It should be noted that the controller mentioned has its own power supply, and its power supply can be designed to be rechargeable or detachable and replaceable.

[0046] Since the airbag body is combined with the shoulder strap 21 and the side strap 22, the larger space of the backpack body 1 can be used to store the inert gas compressed tank 31, so that the user can carry more gas volume, so that the volume of the life-saving airbag can be designed to be larger, which can achieve better life-saving effect.

[0047] Working principle of this utility model:

[0048] This backpack is designed with air bags at the top and middle positions respectively. When the user falls into the water, the air supply part 3 injects gas into the corresponding air bags to make the air bags expand and pop out. The air bags located at the top of the backpack body 1 are responsible for supporting the user's neck, and the air bags located in the middle of the backpack body 1 are responsible for supporting the user's armpits. Through the mutual cooperation of the air bags at the two positions, the buoyancy exceeds 200 kilograms, reducing the probability of the air bags and the user's body separating and causing the user to drown.
