    FIELD OF THE INVENTION
  • [0001]
    The present invention relates to ventilated shoes and more particularly to a pair of ventilated shoes each having independent fresh air inflow path and foul air outflow path such that circulating fresh air in the shoe and driving foul air out of the shoe can be done in a cycle of lifting the foot and setting the foot down.
  • BACKGROUND OF THE INVENTION
  • [0002]
    A well known ventilated shoe is shown in FIG. 1. The shoe 10 comprises an outsole 11, an insole 12, a vamp 13, and a hollow heel 14. The heel 14 is made of plastic material. An enclosed bladder 15 is provided in the heel 14. A curved flow line of air 16 is formed on the outsole 11. The flow line of air 16 comprises a plurality of apertures 161. The flow line of air 16 is in fluid communication with the bladder 15. An air inflow line 17 is extended from the bladder 15. The air inflow line 17 has a check valve 171 and an outlet 172 at an open end. Fresh air is sucked into the air inflow line 17 through the outlet 172 and the check valve 171. The outlet 172 of the air inflow line 17 is connected to a hole 141 at one side of the heel 14. Moreover, a plurality of close apertures 121 arranged in rows and columns are formed on the insole 12.
  • [0003]
    Thus, fresh air is sucked into the bladder 15 through the air inflow line 17 when the foot lifts. Next, fresh air in the bladder 15 is compressed and driven out to flow to various parts in the shoe 10 through the apertures 161 of the flow line of air 16 and the apertures 121 of the insole 12 when the foot sets down. As a result, the person can feel a degree of comfort on his/her foot.
  • [0004]
    However, the prior art suffered from the following disadvantage. The outlet 172 of the air inflow line 17 of the shoe 10 is connected to the hole 141 at one side of the heel 14. As such, water may flow into the bladder 15 via the hole 141 at one side of the heel 14 and the air inflow line 17 when a person wearing the shoes 10 walks in a rainy or snowy day. As an end, all parts in the shoes 10 are wet. This can cause great discomfort to the person. Thus, the need for improvement exists.

    Referring to FIGS. 2 and 3 again, an inflow hose 28 is provided in the shoe 20 proximate its left side and an outflow hose 29 is provided in the shoe 20 proximate its right side. The inflow hose 28 is connected to the left bladder section 251 and the inflow hose 28 has an upper opening. External fresh air can be sucked into the left bladder section 251 through the inflow hose 28 when the foot lifts. Next, fresh air in the left bladder section 251 is compressed and driven out to flow to various parts in the shoe 20 through the line of fresh air 26 and the apertures 261 of the line of fresh air 26 when the foot sets down. Similarly, the outflow hose 29 is connected to the right bladder section 253 and the outflow hose 29 has an upper opening. Foul air in the shoe can be sucked into the right bladder section 253 through the line of foul air 27 and the apertures 271 of the line of foul air 27 when the foot lifts. Next, foul air in the right bladder section 253 is compressed and driven out of the shoe through the outflow hose 29 when the foot sets down.
  • [0016]
    Referring to FIGS. 2 and 3 again, by configuring as above, in a cycle of lifting the foot and setting the foot down external fresh air can be sucked into the left bladder section 251 through the inflow hose 28 prior to flowing to various parts in the shoe through the line of fresh air 26. Likewise, in the same cycle of lifting the foot and setting the foot down foul air in the shoe can be sucked into the right bladder section 253 through the line of foul air 27 prior to driving out of the shoe through the outflow hose 29. By repeating the above cycle, external fresh air can be continuously sucked into the shoe via the left bladder section 251 and internal foul air can be continuously driven out of the shoe via the right bladder section 253. As a result, the person can feel a degree of comfort on his/her foot.
  • [0017]
    Referring to FIGS. 2 and 3 again, in the invention a deodorant chamber 31 is provided at the same side as the inflow hose 28 in the shoe 20. As such, in a cycle of lifting the foot and setting the foot down external fresh air along with the pleasant odor emitted from the deodorant in the deodorant chamber 31 can be sucked into the left bladder section 251 through the inflow hose 28 prior to flowing to various parts in the shoe through the line of fresh air 26. As a result, unpleasant odor in the shoe can also be masked.
  • [0018]
    Referring to FIGS. 2 and 3 again, a plurality of close apertures 221 arranged in rows and columns are formed on the insole 22 of the shoe 20. The apertures 221 of the insole 22 can direct fresh air leaving the left bladder section 251 onto the sole. As a result, the person can feel a degree of comfort on his/her foot.
  • [0019]
    Referring to FIGS. 2 and 3 again, the insole 22 of the shoe 20 is formed of a ventilated material. This enables fresh air leaving the left bladder section 251 to pass the insole 22 prior to directing onto the sole. As a result, the person can feel a degree of comfort on his/her foot.
  • [0020]
    Referring to FIGS. 2 and 3 again, each of the line of fresh air 26 and the line of foul air 27 is implemented as a blood vessel-like member formed in left and right portions of the vamp 23 above the outsole 21 respectively.
