Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 3, a ventilating sandal comprises a sole 1 and a shoelace 2, wherein the sole 1 is internally provided with a compression chamber 3, the compression chamber 3 is provided with a piston member 4, one end of the piston member 4 extends to the outer side of the compression chamber 3 and is provided with an elastic member 5 which is restored after the compression chamber 3 is compressed, the sole 1 is internally provided with a space for the elastic member 5 to deform, the compression chamber 3 is communicated with a ventilating duct 6, the foot-facing side of the sole 1 is provided with a plurality of ravines 7 along the width direction thereof, the ventilating duct is provided with a plurality of ventilating holes 8 which extend to the side walls of the ravines 7, the compression chamber 3 is communicated with the outside through an air outlet 9, by such a structure, when a person walks, the heel continuously deforms the sole 1 to press the piston member 4 to move downward, the volume of the compression chamber 3 is compressed, so that air is discharged from the ventilating holes 8 into the ravines 7 through the ventilating duct 6, because the ventilation holes 8 are formed in both sides of the gullies 7, convection is formed in the gullies 7, so that gas can be blown to the bottom of the feet finally, when a person lifts the feet, the deformation of the sole 1 disappears, the piston piece 4 is reset under the driving of the sole 1, the compression cavity 3 sucks gas through the ventilation holes 8, and the piston piece 4 divides the compression cavity 3 into two cavities, so that the air outlet 9 needs to be arranged as another cavity which is not communicated with the ventilation pipeline 6 for exhausting and supplementing gas.

Further, the ravines 7 are formed to be inclined downward from the middle of the sole 1 toward both sides, and thus, when water flows into the ravines 7, the water can flow out of the sole 1 through the inclined surfaces of the bottoms of the ravines 7.

Further, the sole 1 is provided with air guide grooves 10 communicating with the ravines 7 along the longitudinal direction thereof, and thus, air flows flowing to both sides in the ravines 7 can be utilized to form convection in the air guide grooves 10, so that the air flows can flow along the air guide grooves 10, thereby enhancing the ventilation effect, and simultaneously, water on the surface of the sole 1 can also be divided through the air guide grooves 10, thereby enhancing the drainage effect.

Furthermore, the compression cavity 3 is divided into an upper cavity and a lower cavity by taking the piston piece 4 as a boundary, the vent pipe 6 is communicated with the lower cavity, the air outlet hole 9 is positioned in the upper cavity, the lower cavity is communicated with the outside through the air inlet hole 11, the air inlet hole 11 is provided with the air inlet one-way valve 12, the vent pipe 6 is internally provided with the air outlet one-way valve 14, through the structure, when the lower cavity inhales air, the lower cavity only supplements air from the outside through the air inlet hole 11 and cannot supplement air through the air outlet hole 8 under the action of the air inlet one-way valve 12 and the air outlet one-way valve 14, so that the inhaled air is fresh air from the outside, when the lower cavity exhausts air, the air can only be exhausted through the air outlet hole 8 and cannot be exhausted through the air inlet hole 11 under the action of the air inlet one-way valve 12 and the air outlet one-way valve 14, therefore, all the air can be exhausted, so that no sweat can build up in the ravines 7.

Further, the vent pipe 6 is communicated with a drain hole, and the drain hole is provided with an air plug 13, so that the water flowing into the vent pipe 6 can be discharged through the drain hole, and the air plug 13 can prevent the gas from leaking through the drain hole and prevent the water from entering the drain hole.

Further, the vent pipe 6 is obliquely arranged, and by such a structure, when water enters the vent pipe 6 through the vent holes 8, the water is gathered at the drain holes under the guidance of the oblique vent pipe 6, and then the water is discharged out of the vent pipe 6 by opening the air plug 13.

Further, the sole 1 is made of rubber foaming colloidal particle materials, the rubber foaming colloidal particle materials are made of CPE/CM (chlorinated polyethylene) which is used as a main material with the highest component, POE (polyolefin elastomer), EPDM (ethylene propylene diene monomer), EVA (ethylene vinyl acetate), natural rubber or isoprene rubber and a filling material are combined to form a main body of the rubber foaming colloidal particle, and then auxiliary materials are combined to improve coordination, so that the CPE/CM is fully and coordinately mixed with the POE, the EPDM, the EVA, the natural rubber or isoprene rubber, the density of products is greatly reduced, the sole 1 is ultra-light in weight, and meanwhile, the sole 1 has the effects of stable forming size, high tensile strength, excellent anti-skid and wear-resistant performances, good folding and cold-resistant performances, softness and comfort, and is low-carbon and environment-friendly.

In summary, the working principle of the breathable sandals is as follows: when a person walks on the ground, the heel of the foot presses the sole 1 to deform the sole 1, so that the piston member 4 in the sole 1 moves downwards under pressure and deforms the elastic member 5 under force, the piston member 4 moves downwards to press air in the lower cavity of the compression cavity 3, the air is discharged outwards, the air inlet hole 11 does not participate in the discharge of air due to the fact that the air inlet check valve 12 limits the exhaust, so that the air can be mostly discharged from the air vent 8 through the vent pipe 6 and flows in the gullies 7 and the air guide grooves 10 to take away heat on the foot, so that the temperature is reduced, when the person lifts the foot, the piston member 4 resets under the action of the elastic force of the elastic member 5, the lower cavity replenishes air due to the increase of the volume, at the time, the vent pipe 6 does not participate in the air intake due to the limitation of the air outlet check valve 14, so that the air entering the lower cavity is fresh air sucked from the outside through the air inlet hole 11, therefore, the air discharged from the ventilation holes 8 is fresh air, when water enters from the contact surface of the sole 1 and the sole of the foot, the water is distributed to each of the ravines 7 through the air guide grooves 10 and discharged out of the sole 1 through the inclined surfaces of the ravines 7, and the water entering the ventilation pipe 6 through the ventilation holes 8 can be discharged through the water discharge hole by opening the air plug 13.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
