Detailed Description

The embodiments of the present invention will now be described in detail with reference to the accompanying drawings and specific examples.

Referring to fig. 1-4, the technical scheme of the utility model is as follows:

the utility model provides a waterproof ventilative sole, includes insole 3, locates insole 3 down and 3 fixed connection's in the middle of with insole 6, locate insole 3 with between the big end 6, be located the waterproof ventilative frame 1 at the well waist position of insole 3, the lower surface of insole 3 is equipped with first ventilative recess 8, be equipped with on the first ventilative recess 8 and run through a plurality of bleeder vents 5 of insole 3, bleeder vent 5 is perpendicular first ventilative recess 8 sets up, the well waist position of insole 3 is equipped with one and places the first recess 4 of waterproof ventilative frame 1.

The waterproof breathable frame 1 is identical to the middle waist of the insole 3 in shape and size, the middle of the waterproof breathable frame 1 is hollowed out, circular hole protrusions 9 are arranged at the head and the tail of the waterproof breathable frame, through grooves 10 which can be communicated with external air are formed in the circular hole protrusions 9, the through grooves 10 are communicated with the first breathable grooves 8, the first breathable grooves 8 are communicated with the through grooves 10 and the air passages 5, and spiral bars 2 which are arranged along the length direction of the sole and can accelerate the air circulation rate in the through grooves 10 are arranged in the through grooves 10.

The foot bed surface of insole 3 is equipped with the ventilative recess 7 of second, be equipped with on the ventilative recess 7 of second and run through the bleeder vent 5 of insole 3, it is gaseous on the foot bed surface the ventilative recess 7 of second passes bleeder vent 5 comes the first ventilative recess 8 of 3 lower surfaces in insole, and the helical coiled passage of the spiral rod 2 in the logical groove 10 that the rethread was located the round hole arch 9 comes the external world, realizes circulation of air, exchange.

The middle sole is made of EVA or ETPU materials which are comfortable to wear and environment-friendly, the big sole 6 is made of light and wear-resistant rubber or cast polyurethane elastomer materials, and the waterproof and breathable frame 1 and the spiral rod 2 are made of TPU or nylon materials with high elasticity and high tensile strength.

The utility model discloses a theory of operation:

the instep of insole 3 is equipped with the ventilative recess 7 of second, run through on the ventilative recess 7 of second the bleeder vent 5 of insole 3, inside and external space of sole is connected to bleeder vent 5, the thread clearance of hob 2 forms spiral ventilation channel, bleeder vent 5 the first ventilative recess 8 of sole with locate the spiral channel in the protruding 9 logical groove 10 of round hole of waterproof ventilative frame 1 forms waterproof ventilation channel for gas flow rate promotes gas exchange rate. When a wearer wears the shoe, the damp and hot air of the sole sinks through the air holes 5 on the insole 3 and comes to the first air-permeable groove 8 connected with the spiral rod 2, and is discharged by the air conduction of the spiral air-permeable channel in a spiral running mode, so that the air permeability of the sole is ensured, and the phenomenon of sultriness is avoided; in a humid environment, the air flow inside the sole and the outside is only communicated by the through grooves 10 in the two circular hole bulges 9 of the waterproof and breathable frame 1, and the air with water vapor can enter the sole only through narrow and small spiral channels in the through grooves 10. The outsole 6 is made of rubber or CPU material, the waterproof and breathable frame 1 and the spiral rod 2 are made of TPU or nylon material, and the materials have excellent hydrophobicity and are difficult to attach water vapor under the action of gravity. The clearance between the screw thread of hob 2 and the round hole of waterproof ventilative frame 1 is very little, because surface tension, water can't pass the clearance and get into the sole even there is vapor condensation in first recess 8, also can't pass the 5 bleeder vents of perpendicular to sole recess 8 under the action of gravity and come the shoes bed, therefore, can effectively guarantee the waterproof nature of sole, realize the waterproof ventilative function of sole.

Waterproof ventilative frame 1 is located 3 middle waists of insole and is not forced the groove part, and the screw rod 2 is located in the protruding 9 logical groove 10 of round hole of waterproof ventilative frame 1 along sole length direction, and the person of dress does not receive the feel of the foot when wearing to influence, has guaranteed the waterproof gas permeability and shoes travelling comfort, the practicality of shoes, practices thrift sole manufacturing cost.
