Summary of the invention
Technical problem to be solved by this invention provides a kind of ventilation footwear, and the air bags amount of these ventilation footwear is big, good integral strength, and be convenient to processing, and the exhaust outlet setting of air bag is more hidden.
For this reason, ventilation footwear ventilation footwear provided by the invention, comprise sole, sole heel place be provided with can unidirectional external exhaust air bag, air bag comprises air bag outer cover and air bag cushion, the air bag outer cover covers on the air bag cushion, the cooperation place hermetic seal of air bag outer cover and air bag cushion, the air bag outer cover comprises integrated air inlet pipe and cover body, air inlet pipe has the check valve to the unidirectional air inlet of air bag direction, and the cover body top inner wall is cambered surface and distributes, and the sidepiece of air bag cushion vertically offers groove, the air bag cushion center offers the steam vent that vertically runs through air bag cushion, the air bag cushion top has the sphere pit of indent, and steam vent communicates with the external world, bottom, and steam vent has the check valve of external unidirectional exhaust, the half sole punishment of sole is furnished with air intake duct, and air inlet pipe links to each other with air intake duct.
Because the ventilation footwear that invention provides comprise the air bag that is made of cylindrical air bag cushion and air bag outer cover, this split type bladder configurations is convenient to make more, the rubber that makes its employing longer service life of having ready conditions also makes things convenient at any time the parts that damage is changed as the raw material manufacturing; The arc top surface of air bag interior cylindrical air bag cushion and the sphere pit on air bag cushion top are combined to form the air bag inner chamber of the approximate ellipsoidal of slightly flat, flat and air bag inner chamber that arc distributes is more suitable for the human body vola and compresses, human body weight can be delivered on the air bag outer cover more, thereby the air-flow that compression is produced is more powerful; In addition, the air bag cushion of ventilation footwear provided by the invention is provided with steam vent downwards, the direction that the direction that steam vent extends presses down over against air bag, make flowing of air-flow smooth more, thereby make the exhaust efficiency of ventilation footwear higher, and the extraneous structure of linking up in this steam vent and bottom can not seen the position of air exit easily, thereby can not influence the outward appearance of ventilation footwear.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, comprise sole 1 among a kind of embodiment of ventilation footwear provided by the invention, heel 10 places of sole 1 be provided with can unidirectional external exhaust air bag 2, air bag 2 comprises air bag outer cover 3 and air bag cushion 4, air bag cushion 4 is generally cylindrical, air bag outer cover 3 adopts elastomeric material to make, air bag outer cover 3 covers on the air bag cushion 4, the cooperation place hermetic seal of air bag outer cover 3 and air bag cushion 4, air bag outer cover 3 comprises integrated air inlet pipe 5 and cover body 6, cover body 6 is cylindrical with air bag cushion coupling, cover body 6 top inner wall are cambered surface and distribute, and cover body 6 top inner wall generally are sphere in actual manufacturing, and the sidepiece of air bag cushion 4 vertically offers groove 8, air bag cushion 4 centers offer the steam vent 9 that vertically runs through air bag cushion 4, air bag cushion 4 tops have the sphere pit 19 of indent, and steam vent 9 communicates with the external world, bottom, and steam vent 9 has the check valve of external unidirectional exhaust, the half sole punishment of sole 1 is furnished with the air intake duct 14 of mutual UNICOM, and air inlet pipe 5 links to each other with air intake duct 14.Air bag cushion 4 is the cylinder with sole 1 split in the present embodiment, air bag cushion 4 bottom peripheries have annular outer 7, annular offers annular groove 20 on the outer 7, the lower end of air bag outer cover is to being distributed with ring rib 21 by annular groove, ring rib 21 embeds in the annular groove 20, make the air bag inner chamber keep good air tightness, first groove 11 that offers upward opening in the heel 10 and mate with air bag 2, be provided with step 12 in the annular in first groove 11, first groove, 11 bottoms offer through hole 13 a plurality of and the extraneous communication in bottom, be distributed with on the sole 1 link up the exhaust duct 14 and first groove 11 compile air flue 15, air bag cushion 4 is supported on the interior step 12 of annular, and air inlet pipe 5 is arranged to be compiled in the air flue 15.
As shown in Figure 2, heel 10 bottoms are provided with pit 17 in the above-described embodiments, and the outlet of through hole 13 is in pit 17 centers, and heel 10 bottoms also offer and connect pit 17 and in the air discharge duct 18 of heel 10 bottom outside openings.This structure makes people's sole when walking can not cause the sole outlet of through hole 13 to be closed because of closely contacting with the bottom surface, air-flow can after coming out, through hole 13 be entered in the pit 17, discharge to the side through air discharge duct 18 then, thereby effectively ensure the smooth and easy of exhaust.
Introduce the airflow mode of first kind of ventilation footwear among the embodiment below in detail: 1, when vola compressing ventilation footwear sole 10, air bag 2 is compressed, air-flow is from the air bag 2 inner unidirectional exhausts in space of surrounding formation by steam vent 9 to air bag cushion 4 bottoms and first groove 11, air-flow enters in the pit 17 through through hole 13 afterwards, discharges from the heel sidepiece by air discharge duct 18 at last; 2, when compressing to ventilation footwear heel 10 is loosened in the vola, air bag 2 expansions, suck air, air-flow enters in the exhaust duct 14 in the footwear chamber, entered in the air inlet pipe 5 through compiling air flue 15 by exhaust duct 14, the groove 8 of process air bag cushion 4 sidepieces enters air bag cushion 4 and surrounds (groove 8 has formed an inlet channel with 3 encirclements of air bag outer cover) in the air bag inner chamber that forms with air bag outer cover 3 then again.
As shown in Figure 2, second kind of embodiment provided by the invention and first kind of embodiment are basic identical, its difference only is the set-up mode of air bag 2, air bag cushion 4 is one-body molded with sole 1 in the present embodiment, heel 10 places of sole 1 offer second groove 16, air bag cushion 4 is in second groove 16, the steam vent 9 straight-through external worlds, heel 10 bottom at air bag cushion 4 centers, the outlet of steam vent 9 is in pit 17 centers, be distributed with on the sole 1 link up the exhaust duct 14 and second groove 16 compile air flue 15, air inlet pipe 5 is arranged to be compiled in the air flue 15.The integrally manufactured structure of this air bag cushion 4 with air bag 2 and sole is different from traditional monomer air bag and is arranged on structure in the sole groove, this structure of the present invention makes air bag more firm with combining of footwear, and air bag cushion 4 can with sole die cast together, be convenient to processing and manufacturing.
Introduce the airflow mode of second kind of ventilation footwear among the embodiment below in detail: 1, when vola compressing ventilation footwear sole 10, air bag 2 is compressed, air-flow, is discharged from the heel sidepiece by air discharge duct 18 to the 17 unidirectional exhausts of sole pit then from the air bag 2 inner steam vents 9 that pass through; 2, when compressing to ventilation footwear heel 10 is loosened in the vola, air bag 2 expansions, suck air, air-flow enters in the exhaust duct 14 in the footwear chamber, entered in the air inlet pipe 5 through compiling air flue 15 by exhaust duct 14, the groove 8 of process air bag cushion 4 sidepieces enters air bag cushion 4 and surrounds (groove 8 has formed an inlet channel with 3 encirclements of air bag outer cover) in the air bag inner chamber that forms with air bag outer cover 3 then again.
