Detailed description of the invention
Elaborate below in conjunction with the detailed description of the invention of accompanying drawing to the utility model air-blowing.
See accompanying drawing 1, air-blowing comprises air bag 1, and air bag 1 is made up of materials such as elastic silica gels, automatic rebounding after extruding, and the head of air bag 1 is provided with blow gun 2, and be through hole in blow gun 2, the inlet end of blow gun 2 is sealed and matched with air bag 1 and is communicated by air inlet.
See accompanying drawing 2,3, unidirectional air outlet valve 3 is provided with in the inlet end of blow gun 2, unidirectional air outlet valve 3 is elastomeric material, silica gel or elastomeric material can be selected, the inlet end of blow gun 2 has installing hole, unidirectional air outlet valve 3 sealing is arranged in installing hole, can arrange interior step in installing hole, and the upper end of unidirectional air outlet valve coordinates fixing with interior step.
Unidirectional air outlet valve 3 is the middle tubular cylinder having through hole 4, described tubular cylinder front end is provided with head valve block 5, the diameter of described head valve block 5 is less than the external diameter of described tubular cylinder, the part side of described head valve block 5 is connected with the end of described tubular cylinder, described head valve block 5 covers in the intermediate throughholes 4 of described tubular cylinder, when the through hole both sides of unidirectional air outlet valve 3 exist pressure differential, described through hole 4 is opened or is sealed by described head valve block 5.Head valve block 5 side of described unidirectional air outlet valve 3 is positioned at the side, outlet side of described blow gun 2.
See accompanying drawing 4, the afterbody of air bag 1 is provided with one-way air inlet tail plug 7, the centre of tail plug 7 has through hole, the side being positioned at air bag 1 at tail plug 7 is provided with afterbody valve block 8, the part side of afterbody valve block 8 is connected with tail plug 7 end, afterbody valve block 8 covers in the intermediate throughholes of tail plug 7, and when tail plug 7 through hole both sides exist pressure differential, through hole is opened or sealed by afterbody valve block 8.
Tail plug 7 is filled in air bag 1 afterbody installing hole, unidirectional air outlet valve 3 is arranged in the installing hole of blow gun 2 inlet end, then blow gun 2 is loaded in air bag 1 head installing hole, complete the installation of air-blowing.
During use, extruding gasbag 1, air pressure in air bag 1 increases, and after the afterbody valve block 8 of tail plug 7 is subject to air pressure, sealed by the through hole of tail plug 7, afterbody can not be given vent to anger.After unidirectional air outlet valve 3 in the blow gun 2 of head is subject to air pressure, the head valve block 5 of unidirectional air outlet valve 3 opens, and gas goes out blowout from blow gun 2, completes and once blows.Unclamp air bag 1, air bag 1 automatic rebounding, air bag 1 inside forms negative pressure, after unidirectional air outlet valve 3 in the blow gun 2 of head is subject to air pressure, head valve block 5 is due to himself elastic force and the air pressure that is subject to, and sealed by the through hole 4 of unidirectional air outlet valve 3, gas cannot enter in blow gun 2.The afterbody valve block 8 of the tail plug 7 of afterbody is opened by pressure, and gas enters air bag 1 from afterbody, completes an air-breathing.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
