Description

Footbed with external air circulation

technical field

The utility model relates to a footbed with external air circulation, in particular to an improved structure of the footbed so that it has the function of good ventilation.

Background technique

The footbed of general leather shoes is usually made of solid leather or rubber or plastic material. If it is equipped with special functions, it has an air cushion structure to act as a buffer for shock absorption, but it does not have the function and effect of ventilation.

Although the special footbeds of some children's shoes have the structure of an air chamber, they are only designed for sending out the whistle-like sound, and there is not much use function to speak of.

In order to achieve a breathable effect, sports shoes are usually provided with several openings on the inner edge of the foot to allow heat to exchange and circulate here. However, the real hot spot or uncomfortable point is between the toes. But in fact, it can't achieve good antipyretic and breathable functions.

Utility model content

The purpose of the utility model is to provide a footbed with external air circulation.

The utility model belongs to a footbed with external air circulation. According to its structure, an air suction port is provided at the toe end of a footbed, a compressed air chamber is hidden at the heel end, and an air chamber is also hidden on the bottom of the foot. aisle.

The utility model belongs to a footbed with external air circulation, wherein the toe end of the footbed is provided with several air suction holes arranged like toes, and secondary air suction holes can be arranged at appropriate places, and Connected to the air chamber channel below.

The utility model belongs to a footbed with external air circulation, in which a main compressed air chamber is arranged inside the heel end of the footbed, which is composed of an elliptical spherical elastic airbag and connected with several air chamber passages. When it is pressed, the gas in the original inside is squeezed out, and when it is not under pressure, it rebounds by itself and sucks in the gas.

The utility model belongs to a footbed with external air circulation. In addition to hiding several air chamber channels and air valve devices on the sole surface of the footbed, two smaller air chamber channels are arranged at the front end of the air chamber channel. The compressed air chamber is also provided with a one-way air discharge hole at the left and right side ends, and a powerful air inlet hole for the ball needle is provided at the outer front end.

The utility model is characterized in that the fresh air outside the shoes is sucked into the compressed air chamber, and the one-way air discharge hole discharges the retained air extruded from the compressed air chamber to the outside of the shoes, forming a footbed structure for external air circulation , so as to achieve good antipyretic and breathable functions.

Detailed ways

Please refer to Fig. 1, which is a plan perspective view of the footbed structure of the present utility model, wherein at the toe end of the footbed 10, there are several air suction holes 11 arranged like toes, and secondary air suction holes can be arranged at appropriate places. The holes 101 are all connected to the air chamber channel 12 below.

Please refer to Fig. 1 again, wherein on the sole surface of the footbed 10, in addition to hiding several compressed air chambers 13, it is formed by an ellipsoidal elastic airbag, and connected with several air chamber passages 12, when the gas in the original interior is compressed. It will be squeezed out, and when it is not under pressure, it will rebound by itself and suck in gas.

Still please refer to Fig. 1, wherein on the sole surface of the footbed 10, in addition to hiding several air chamber passages 12 and the air valve device 14, and at the front end of the air chamber passage 12, two smaller compressed air chambers 103 are provided. In addition, the left and right side ends are respectively provided with a one-way air discharge hole 15,16, and then at the outer front end, a powerful air intake hole 17 for a ball needle is provided.

As mentioned above, the air valve device 14 and the one-way air discharge holes 15, 16 have the same or similar structure, so that the flow direction of the gas is limited to one-way, and if it is reversed, it will be blocked.

Another example is that the aforementioned air valve device 14 and the one-way air discharge holes 15, 16 constitute the air flow throttling device with the spring bead body 18, but the air valve device 14 can only pass through the air suction hole 11 to inhale the fresh air outside the shoes. The air enters the compressed air chamber 13, and the one-way air discharge holes 15, 16 discharge the trapped air extruded from the compressed air chamber 13 to the outside of the shoe, forming a footbed structure for external air circulation.

Such as the powerful air inlet 17 for the aforementioned ball needle, when necessary, insert the ball needle from the powerful air inlet 17 to the air chamber channel 12 from the outside to the inside, and then use the pump to pour in the instantaneous strong gas, and let the gas separately Exhaust from the air suction port 11 and the one-way air discharge holes 15, 16 to get through possible blockages, and the compressed air chamber 13 at this time is in an inflated state.

Claims (3)
