As shown in FIGS. 2 and 3, the air pumping unit 200 is formed of a rectangular tube body and is communicatively coupled to the air inlet / outlet unit 100 described above. In addition, the suction inlet discharge pressure is applied to the air inlet and outlet means 100 so that the air inside the shoe is discharged to the outside. Here, the air pumping unit 200 is composed of a coupling end portion 210, the shape maintaining portion 220.

The coupling end 210 is protruded so that the other side of the air inlet and discharge means described above is coupled to one side of the air pumping unit 200 formed of a rectangular tube body. Here, the suction discharge pressure generated by the air pumping unit 200 of the tube body is transmitted through the coupling end 210 to allow one-way suction and one-way discharge of the air inlet and discharge means.

The shape maintaining part 220 is formed up and down to maintain the shape of the tube body to the center of the rectangular tube body. Here, the shape holding part 220 is a fast pumping force so that the air pumping portion 200 contracted by an external force is quickly relaxed to the original state more effectively so that the suction pressure and the discharge pressure are transmitted to the air inlet and discharge means 100 described above. It is formed to be provided.

On the other hand, the air pumping unit 200 is formed as a rectangular tube body as shown in the figure, it is preferable that it is formed in various shapes according to the space inherent in the shoe.

The operation and effects of the one-way nozzle structure of the breathable shoe of the present invention according to the configuration as described above will be described in detail by way of examples.

As shown in FIG. 1, first, the air inlet and discharge means 100 of the present invention is coupled to the coupling end portion 210 of the air pumping part 200 at the heel side of a shoe having a plurality of flow paths (not shown). Airtight. Here, as shown in FIG. 3, the first and second valve bodies 140 and 160 toward the respective engaging step 122 '126' on the inlet 122 and outlet 126 sides of the air inlet and outlet means 100 are provided. ) Respectively. The coupling of the first and second valve bodies 140 and 160 may be performed between the inlets 144a and 164a and the outlets 144b and 164b of the flow holes 144 and 164 formed through the respective valve bodies 142 and 162 as described above. The blocking members 146 and 166 are placed in the blocking member supporting parts 144c and 164c formed in the sealing member so as to be opened and closed between the inlet and the outlet.

At this time, the blocking members 146 and 166 may have center adjustment pieces 146b and 166b having the same width as the inner diameter of the inlet so as to be exactly positioned in the center of the inner diameter of the blocking member supporting portions 144c and 164c, that is, the inner diameter of the inlets 144a and 164a. By accurately positioned in the center of the blocking member support (144c, 164c) by the blocking plate 146a, 166a is to accurately seal the airtight state in the blocking member support.

In this way, the one-way nozzle structure of the present invention coupled to the breathable shoes when the user walks by wearing shoes, the first air pump 200 is contracted shrinkage of the user's weight in the heel of the foot. Then, as shown in Figure 6, the contracted air pumping unit 200 is a repulsive action to return to the original state by the shape maintaining unit 220 is generated, the moment the user lifts the heel of the shoe contracted air pumping The unit 200 relaxes and returns to its original state.

At this time, the suction tube is generated as the tube contracted like the dropper of the test apparatus is returned by the return of the air pumping part 200 and the object fluid is sucked. Thereafter, the blocking plate 146a of the first valve body 140 of the air inlet and outlet means 100 is lifted toward the air pumping part 200 by the suction force generated by the air pumping part 200, The contaminated air is sucked through the suction part 122 of the suction discharge pipe 120 of the “ㅏ” type and flows into the air pumping part 200.

Here, the suction force stops at the highest point where the air pumping unit 200 is restored to its original state by the shape maintaining unit 220. Therefore, the blocking plate 146a is returned to the blocking member support part 144c at the stop point of the suction force and sealed again so that the polluted air sucked from the air pumping part 200 does not flow back as the suction force is stopped.

Next, as shown in FIG. 5, when the user contacts the ground with the heel for walking, the air pumping unit 200 contracts again. At this time, as the air pumping part 200 contracts, the contaminated air sucked into the air popping part 200 is compressed and discharged by a high discharge pressure toward the coupling end 210. At this time, the polluted air to the side of the first valve body 140, the blocking plate 146a blocks the suction portion 122 of the "흡입" type suction discharge pipe 120 by the discharge pressure.

Therefore, the polluted air is not discharged to the suction unit 122, and while the vortex is generated in the suction discharge pipe 120 of the "ㅏ" type, the polluted air due to the high discharge pressure moves to the second valve body 160 side.

Subsequently, the moving polluted air is pushed up by the discharge pressure through the blocking plate 166a of the blocking member 166 through the distribution hole 164 formed in the valve body 162 of the second valve body 160. Discharge to outside via 164b). That is, the first valve body 140 serves as one-way suction of the contaminated air in the shoe, and the second valve body 160 plays a role of one-way discharge of the contaminated air in the shoe more effectively. Polluted air can be discharged to the outside.

The first and second valve bodies 140 and 160 having different functions of suction and discharge are provided in the suction type discharge pipe 120 of the “형” type, so that a high suction pressure and a discharge pressure can be attained more effectively. It is obvious that the polluted air can be discharged, and thus comfortable shoes can be worn.

Meanwhile, the blocking plates 146a and 166a of the first and second valve bodies 140 and 160 are divided into elliptical shapes so that the push tips 148b and 168b protruding below the fixed caps 148 and 168 correspond to the central diameters of the elliptical shapes. It is formed in a width and presses the blocking plate (146a, 166a) in accordance with the flow of air in the inlet 122 and outlet 126, respectively, the left and right each can be operated independently of the two valve body in one valve body It is to play the same role.
