Description

Multifunctional backpack

Technical field

The utility model belongs to knapsack technical field, more particularly to a kind of multifunctional backpack.

Background technology

With the continuous development of society, knapsack gradually comes into the visual field of people, and is widely used in masses, to people's Life brings great convenience, and with being on the increase for the market demand, knapsack is also more and more therewith, the back of the body in the market Ladle sample formula is different, and species is various, but also there is some weak points more or less, existing market for the knapsack nowadays sold Upper all packsacks are all the effects of traditional storage article, and except filling thing, practicality is very single, and outward appearance does not have too substantially Big change.Traditional Bag-making industry never has the product for creating and meeting epoch needs, does not also jump out to wrap and only does The thinking of collecting bag.

Utility model content

For in the prior art the defects of, the utility model provides a kind of multifunctional backpack, can solve existing knapsack Function is single, only realizes the problem of storing function.

A kind of multifunctional backpack provided by the utility model, including knapsack body, brace, air bag and filter；

The brace is arranged on the back side of knapsack body；

The air bag is arranged on the side of knapsack body, and air bag is provided with the charge and discharge tracheae being used for air bag inflation/deflation, institute State charge and discharge tracheae and be provided with the valve for being used for being opened and closed charge and discharge tracheae；

The filter cover closes the front for being arranged on knapsack body, in the space that filter cover closes and air intake duct one End is connected, and the other end of the air intake duct is used to be put into mouth or nose to be breathed.

So, the utility model can regard common knapsack in the case of usually and use, when in the wild or nearly aqua region When, can by other are injected in air bag, expanding air bag charge and discharge tracheae, so when people is fallen into water, air bag because Expansion produces buoyancy in water, prevents people from drowning, when when fire or chemical spill, air bag can be regarded emergent Oxygen source, user can suck other in air bag by charge and discharge tracheae；When user is in high dirt region, penetrating odor area When domain or haze region, it can be breathed by air intake duct, and the powder in high dirt region, penetrating odor region or haze Dirt, harmful substance or haze particle etc. are then adsorbed by filter.

Further, the air bag is two and is interconnected that two air bags are symmetrical set in the side of knapsack body Face.

So, two air bags can increase aeration quantity, the volume of augmented airbag, be effectively guaranteed oxygen source it is sufficient and Increase buoyancy in water.

Further, for the filter between two air bags, filter includes filter screen fixed part and filter screen, institute State filter screen fixed part cover and close the front for being arranged on knapsack body, the middle part of filter screen fixed part is hollow-core construction, and the filter screen is removable That unloads is arranged in the hollow-core construction.

So, after user breathes a period of time by air intake duct, filter screen because adsorbing more dust, harmful substance or Haze particle cause filter screen can not normal use, by being changed to filter screen, user can be exhaled by air intake duct again Inhale, air is filtered again.

Further, in addition to sunbonnet, the sunbonnet are fixed on the front of knapsack body by snap-fastener and are located at The lower section of filter.

So, when user is under blazing sun, by pressing snap-fastener, remove sunbonnet and be worn on the head, both can be to prevent Only head is tanned severely.

Further, the openend of the sunbonnet is provided with the stretch cord for elastic sunbonnet.

Further, the described one end of charge and discharge tracheae away from air bag is provided with the first protective case.

So, the first protective case is used to protect charge and discharge tracheae, avoids inflation/deflation because dust blocks, is given in user with mouth It is also more hygienic during air bag gas transmission.

Further, the one end of the air intake duct away from filter is provided with the second protective case.

So, the second protective case is used to protect air intake duct, avoids air intake duct because dust blocks, suction is being not used in user On tracheae, air intake duct more safety and sanitation can be made by the way that the second protective case is enclosed on air intake duct.

Further, the brace is made up of elastomeric material, and centre is provided with interlayer, and medical pack is provided with the interlayer.

So, pack can use as emergency drug, during especially with person in the wild or in hazardous environment.

Further, the downside of the knapsack body is provided with feet.

So, feet can cause knapsack body is more stable to place in other environments.

Beneficial effect：Compared to traditional knapsack, the utility model is in addition to function of containing articles, also with following work( Can, the air bag set up becomes big by gas transmission expansion, can both do lifebuoy use, can also be in fire or chemical spill etc. In the case of as oxygen source use；Meanwhile filter to the travel fatigue in air, particle or harmful substance can adsorb Filter, is effectively protected the body space of user out of doors；Also, the utility model is additionally provided with sunbonnet and pack, the sun Cap can be used for avoiding heat or rain-proof, pack can then use under some emergency cases as emergency drug.
