5, battery 51 and two blower fans 52 are mounted with Fan Box, battery fan provides power supply, and the on & off switch of power supply is located at Fan Box
Outer wall, relevant position makes on & off switch exposed outside by switching keyhole provided with switch keyhole on Fan Box set;The air-out of blower fan
Mouth sequentially passes through the air outlet on Fan Box and Fan Box set wall, and set is connected to the air inlet below an airduct respectively, makes wind
The wind of machine blowout enters Gas inlet tube, is then blown out by venthole;Relevant position on Fan Box and Fan Box set side wall is provided with
Air-inlet grille.
Inclusion front of the described slide fastener around the side of inclusion and away from airduct is set.
The fixing end of described brace is located on the inclusion above airduct outer wall or airduct, and the fixing end of regulation band passes through spiral shell
Nail is fixed on airduct bottom or sewing on the Fan Box set below airduct, and the free end of brace and the free end of regulation band pass through
Adjusting button is connected.
Described airduct is made using rubber or metal.
Fan Box is square box, and the endoporus formation negative and positive that Fan Box covers with Fan Box coordinate.
Airduct top seal.
Beneficial effect
The 1st, two airducts are set on inclusion, and airduct is provided with venthole, opens after on & off switch, blower fan work, to airduct
In be blown into air-flow, these air-flows blow to the back of knapsack people from venthole again, knapsack people is felt nice and cool, reduce perspire.
Embodiment
As shown in figures 1 and 3, a kind of student's school bag, is mainly made up of two symmetrical braces 2 of inclusion 1 and left and right, in the back of the body
Band lower section sets regulation band 3.
School bag towards on the wall at back provided with top-down two outwardly protruding airducts 4 parallel to each other, institute
The airduct stated is hollow, and venthole is provided with towards back and towards two end faces of another airduct.Airduct is bonded on inclusion, or
Many nails are nailed on from inclusion inwall to the direction of airduct or many screws are screwed on, airduct is fixed on inclusion wall.
In school bag bottom provided with Fan Box set 6, the part that Fan Box set 6 is connected with inclusion is provided with slide fastener 7, Fan Box set 6
Interior be provided with Fan Box 5, Fan Box is mounted with battery 51 and two blower fans 52, and battery fan provides power supply, the switch of power supply
Key is located at blower fan outer box wall, accordingly, Fan Box set on also be provided with switch keyhole, make on & off switch by switch keyhole it is exposed
It is outer to be easy to operation.
The air outlet of blower fan sequentially passes through the air outlet on Fan Box and Fan Box set wall, and set is connected to an airduct respectively
The air inlet of lower section, makes the wind that blower fan is blown out enter Gas inlet tube, is then blown out by venthole;On & off switch is provided with Fan Box,
Air-inlet grille is provided with the side wall of Fan Box.
Inclusion front of the described slide fastener around the side of inclusion and away from airduct is set, and is unziped, it becomes possible to by wind
Machine box is removed or placed into out of Fan Box set.When Fan Box is put into Fan Box set, the air outlet of blower fan is directed at blower fan
The air outlet that box is put, the air outlet of blower fan could connect together with the air inlet below airduct.When needing to change battery, draw
Slide fastener is opened, Fan Box is taken out out of Fan Box set battery is changed, changed after finishing, then Fan Box is put back into blower fan
In box set, then zip up.
During blower fan work, air is sucked from air inlet, air-flow is directly sent into by airduct by the air outlet of blower fan after pressurization
The air inlet of lower section.
After back school bag, switch is opened, blower fan obtains power supply from battery and started working, and air pressurized is sucked from air-inlet grille
The air inlet of after-blow blast pipe, then from venthole blowout, the back of knapsack people is blowed to, knapsack people is difficult perspiration.
Because the back of knapsack people can block the venthole of a part, but some outlet all the time during walking about
Hole is not plugged up, for example, be located at the venthole of side, therefore, it becomes possible to maintain the back of the body that air-flow constantly blows to knapsack people
Portion, makes knapsack people feel nice and cool and is difficult to perspire.
The fixing end of described brace is located on the inclusion above airduct outer wall or airduct, and the fixing end of regulation band is located at wind
Guan Shang, the free end of brace is connected with the free end of regulation band by adjusting button.
Described airduct is made using rubber or metal.The rubber that airduct preferably has certain elasticity makes, it is to avoid make
Airduct is obtained during and coughs up very much back pain firmly.
When needing cleaning, unzip and 7 Fan Box is taken out cleaned again, cleaning dry it is dry after Fan Box is put into again
In Fan Box set, the air inlet socket of the air outlet and airduct of blower fan is zipped up again and just can continue to use.
Fan Box is square box, and the endoporus formation negative and positive that Fan Box covers with Fan Box coordinate.
Airduct top seal, makes air-flow can only be from the venthole blowout on airduct.
Above-described embodiment is intended merely to the purposes of the interpretation present invention, and is not limitation of the present invention, this technology
The those of ordinary skill in field, in the essential scope of the present invention, makes a variety of changes or substitutes, and should also belong to the guarantor of the present invention
Protect category.
