Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

The following describes an embodiment of the present invention according to its overall structure.

A drowning prevention life-saving backpack comprises a backpack body 1, a backpack cover 2 and shoulder straps 3, wherein life-saving components 5 are arranged on the backpack body 1 and the backpack cover 2, as shown in figures 1, 2, 3, 4 and 5.

Specifically, lifesaving subassembly 5 includes shell 501, shell 501 bottom one side is connected with the first filter screen 509 that is used for placing impurity entering, shell 501 inside one side is connected with and is used for preventing the moisture from getting into and preventing that water from lasting the sealing plug 512 of pouring into, be connected with two telescopic links 513 and extension spring 514 on the sealing plug 512 respectively, shell 501 internal connection has two second filter screens 510 that are used for preventing tablet 511 displacement, the inside tablet 511 that is provided with the effervescent tablet and makes of shell 501 is as the reactant who produces carbon dioxide, venthole 515 has been seted up to shell 501 bottom opposite side, thereby it takes place to avoid forgetting to open the drowned phenomenon that the gasbag caused to need not manual opening.

Concretely, lifesaving component 5 still includes side gasbag 502, the outside surface of side gasbag 502 is connected with two front end gasbags 503 respectively through two gas-supply pipes 504, gas-supply pipe 504 adopts the hose to make, two front end gasbags 503 are connected respectively on two shoulder straps 3, the knapsack lid 2 back is provided with floats gasbag 506, it is connected with hose 505 to float between gasbag 506 surface and another shell 501, as the pipeline of carrying carbon dioxide in floating gasbag 506 simultaneously as the rope of preventing losing of floating gasbag 506, it is connected with magic tape matte 507 and magic tape hook face 508 to float between gasbag 506 and knapsack lid 2, through the floating gasbag 506 that is the floater, increase the stability when user floats.

Referring to fig. 1 and 2, in the above embodiment, the top of the backpack body 1 is connected with the backpack cover 2, the back of the backpack cover 2 and the back of the backpack body 1 are both connected with the magnetic buttons 4, and the two sides of the outer surface of the backpack body 1 are both connected with the shoulder straps 3, so as to conveniently store articles.

Referring to fig. 2, 3, 4 and 5, in the above embodiment, the hook and loop fastener 507 is fixedly connected to the floating air bag 506, the hook and loop fastener 508 is fixedly connected to the backpack cover 2, the hook and loop fastener 508 is in a shape of a Chinese character 'kou', the floating air bag 506 is detachably connected to the backpack cover 2 through the hook and loop fastener 507 and the hook and loop fastener 508, the sealing plug 512 is slidably connected to the housing 501, and the diameter of one side of the sealing plug 512 is greater than that of the other side of the sealing plug 512, so that the drowning phenomenon caused by forgetting to open the air bag is avoided without manual opening, and the floating air bag 506 serving as a floating ball increases the floating stability of users.

Referring to fig. 1, 2 and 5, in the above embodiment, the housing 501, the first filter screen 509, the sealing plug 512, the tension spring 514 and the air outlet 515 are all provided with two, and the two first filter screens 509, the sealing plug 512, the tension spring 514 and the air outlet 515 are respectively disposed in the two housings 501, the second filter screen 510 and the telescopic rod 513 are all provided with four, and the four second filter screens 510 and the telescopic rods 513 are respectively disposed in the two housings 501, thereby avoiding the drowning phenomenon caused by forgetting to open the air bag without manual opening, and simultaneously increasing the stability of the user when floating through the floating air bag 506 as a floating ball.

The implementation principle of the embodiment is as follows: firstly, in daily use, the shell 501 is blocked by the sealing plug 512 to prevent external moisture from entering the shell 501 to react with the tablets 511, the tablets 511 adopt effervescent tablets which can generate a large amount of carbon dioxide gas after meeting water so as to be convenient for expanding a plurality of air bags, meanwhile, sundries are prevented from entering the shell 501 to block the structure by the arrangement of the first filter screen 509, meanwhile, the tablets 511 are limited by the arrangement of the second filter screen 510, the tablets 511 are prevented from rolling randomly to block the air outlet 515 after bumping, entering the air bags and influencing the movement of the sealing plug 512, and when the floating air bag 506 falls off, the floating air bag 506 can be installed on the backpack cover 2 again by the magic tape;

the side airbag 502 and the front airbag 503 are expanded, when drowning occurs, water passes through two first filter screens 509 and respectively enters two shells 501, then the sealing plug 512 is driven by water pressure to move towards the direction of the tablet 511, so that the water is deeply inserted into the shells 501 to be contacted with the tablet 511, meanwhile, the sealing plug 512 is guided by the telescopic rod 513, a large amount of carbon dioxide gas is generated after the tablet 511 is contacted with the water, then the carbon dioxide gas enters the side airbag 502, the air pipe 504 and the front airbag 503 through the air outlet 515 to expand the side airbag 502 and the front airbag 503, meanwhile, the air pressure pushes against the sealing plug 512 to ensure that the sealing plug 512 is reset to prevent the water from being continuously filled into the side airbag 502, the air pipe 504 and the front airbag 503 to ensure that the stressed area of the air pressure surface of the side airbag 512 is increased due to the diameter of one side of the sealing plug 512 being larger than the diameter of the other side airbag, buoyancy is generated in the water after the side airbag 502 and the front airbag 503 are expanded to support the backpack, so that users are lifted up, so as to reduce the occurrence of the drowning phenomenon, and meanwhile, the front airbag 503 also has buoyancy in front of the users to prevent the safety hidden danger that the users press the sealing plug upwards;

the floating air bag 506 is expanded, the other shell 501 inflates the floating air bag 506 through the hose 505 to enable the floating air bag 506 to be expanded and push the backpack cover 2 open, after the floating air bag 506 is expanded, corners are raised to enable the magic tape rough surface 507 to be separated from the magic tape hook surface 508, so that the floating air bag 506 is separated from the backpack cover 2 to be used as a floating ball to enable a user to hold the front and rear buoyancy of the balance conveniently, and meanwhile, the hose 505 is used as an anti-lost rope to prevent the floating air bag 506 from being lost;

the repacking, this technical scheme can use with the manual formula compressed gas jar of prior art inflation airbag cooperation simultaneously, can be manual can play dual fail-safe again automatically, can effectually avoid drowned phenomenon to take place.

Although embodiments of the present invention have been shown and described, it is intended that the present embodiments be illustrative only and not limiting to the invention, and that the particular features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples, and that modifications, substitutions, variations, and the like, which are not inventive in light of the above teachings, may be made to the embodiments by those skilled in the art without departing from the principles and spirit of the present invention, but are to be construed as broadly as the following claims.
