Abstract

The utility model relates to a pair of cover pads in the shoes with the function of ventilation. Each cover pad is composed of a pad sheet with an interlayer internal cavity structure and an upper cover, wherein, the internal cavities of the pad sheet are divided into a front cavity and a rear cavity through a unidirectional valve; the front cavity is filled with sponges 1 and provided with vent holes; the rear cavity is provided with a reset spring and provided with an air inlet passage which is communicated with atmosphere. The cover pads finish fresh air intake and discharge in the internal cavities of the cover pads by completely depending on the action of the cover pads and the action is formed by the method that volas naturally touch ground in the process of walk of wearers so as to achieve air exchange between shoe insides and shoe outsides. The utility model has the advantages of scientific design, simple and rational structure, good effect, comfort and sanitation, which is suitable for various shoes, particularly for shoes with poor ventilation property.

Description

Sleeve gasket in the ventilation type footwear

The utility model relates to shoe-pad, especially a kind of interior sleeve gasket of footwear with ventilatory.

Shoe-pad is adopted by a lot of people as the assistant product of footwear, and its effect is the sweat that increases the pliability of sole and absorb sole in the footwear, thereby makes the wearer feel comfortable.Yet as the material of shoe-pad making, moisture absorption ratio is the end very at present, so when wearing, in the footwear because the perspiration of pin becomes very moist, and can be owing to relatively seal in the footwear and produce niff, foot palm part is in for a long time in the environment of such sealing and very easily causes various disease of skin.

The purpose of this utility model is the deficiency that exists at above-mentioned shoe-pad, provides a kind of and can keep footwear inner drying health, can increase the interior sleeve gasket of ventilation type footwear of its pliability again.

Sleeve gasket comprises in the ventilation type footwear of the present utility model, pad and disposed thereon pulling a cart beside the shafts, it is characterized in that: pad is the interlayer inner-cavity structure, with the arch of the foot position is the boundary, and this pad inner chamber is separated into former and later two air cavitys, is provided with a check valve between two air cavitys, be filled with sponge in the ante-chamber of pad, the surface layer of pad is offered the steam vent that communicates with ante-chamber, is provided with back-moving spring in the back cavity of pad, and this back cavity is provided with an inlet channel that can communicate with atmosphere.

The design principle of sleeve gasket is in the utility model ventilation type footwear: rely in wearer's walking the sole active force that lands, the back cavity that impels pad is constantly from sucking fresh air with the logical inlet channel mutually of atmosphere.Rely on the active force of slapping behind the pin then, the fresh air that sucks back cavity is entered ante-chamber from check valve, because entering the gas of ante-chamber, the effect of check valve can not blow back into back cavity, when the air pressure in the ante-chamber was increased to a certain degree, the gas in the pad ante-chamber was just discharged to enter in the footwear by the steam vent of mat surface layer under the effect of ball of foot and is discharged from running-on behind the cover.So circulation makes in the footwear and forms exchange gas with airspace, reaches the purpose of going damp health in the footwear.

Sleeve gasket design science in the ventilation type footwear of the present utility model, rational in infrastructure, simple, rely on the power that sole lands naturally in wearer's walking process to realize that the gas in the footwear exchanges fully, effective, and because the effect of pad inner chamber is worn soft more comfortable.Sleeve gasket is applicable to various footwear in these footwear, is specially adapted to the footwear of gas permeability difference.

Concrete structure of the present utility model is provided in detail by the following drawings and embodiment.

Fig. 1 is the structural representation of sleeve gasket in the ventilation type footwear.

Embodiment: can be clear that from Fig. 1, cover is lined with a pad 3 that is provided with ante-chamber 1 and back cavity 2 in the ventilation type footwear, ante-chamber 1 is the boundary with back cavity 2 with the arch of the foot position, be provided with a check valve 4 therebetween, be filled with sponge 5 in the ante-chamber 1, to increase the flexibility of pad 3, be provided with back-moving spring 6 in the back cavity 2, ante-chamber 1 surface layer of pad 3 is furnished with the steam vent 7 that connects with ante-chamber 1, the root of back cavity 2 be provided with one with the extraneous inlet channel 8 that communicates, this inlet channel 8 is arranged on pulls a cart beside the shafts in 9.
