Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, specifically a composite one-way airbag. Background Technology

[0002] To enhance shoe breathability, one existing technology uses a one-way airbag with both intake and exhaust. The airbag's intake end connects to the inside of the shoe, while its exhaust end connects to the outside. Gas inside the shoe enters the airbag through the intake end and exits through the exhaust end, thus improving breathability. However, existing airbags often use an elastic element as a reset mechanism. If the elastic element has a high stiffness coefficient, the airbag is often difficult to compress, resulting in poor exhaust and low air intake. If the elastic element has a low stiffness coefficient, the airbag rebounds slowly, also resulting in poor air intake. Furthermore, the fullness of the airbag after rebound depends entirely on the material of the airbag body, often resulting in pits and depressions at the edges (away from the elastic element). Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the prior art and provide a composite unidirectional airbag that uses elastic elements with two stiffness coefficients to meet the airbag's intake and exhaust requirements.

[0004] To achieve the above objectives, this utility model employs the following technical solution: A composite one-way airbag includes a bag body, the bag body being provided with a one-way air inlet connector and a one-way air outlet connector, the bag body being filled with a first elastic element, a second elastic element being embedded in the first elastic element, and the stiffness coefficient of the second elastic element being greater than that of the first elastic element.

[0005] Preferably, the first elastic element is an elastic filler, and the second elastic element is a tower spring.

[0006] Preferably, the elastic filler is a sponge.

[0007] Preferably, the elastic filler is provided with a vertical through hole adapted to the tower spring.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention incorporates two types of elastic elements with varying stiffness coefficients within the airbag to meet the airbag's intake and exhaust requirements. The airbag is filled with a first elastic element, which fills the airbag completely when no force is applied, allowing it to store a larger volume of gas. Simultaneously, a second elastic element is embedded within the first elastic element, and the stiffness coefficient of the second elastic element is greater than that of the first. This second elastic element provides greater elasticity, ensuring the airbag can quickly rebound. The combination of the rapidly rebounding second elastic element and the first elastic element filling the airbag ensures effective air intake and exhaust. Attached Figure Description

[0012] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0013] Example: As attached Figure 1-2 As shown, the present invention is a composite one-way airbag, including a bag body 1, which may be made of rubber. The bag body 1 is provided with a one-way air inlet connector 2 and a one-way air outlet connector 3. Both the one-way air inlet connector 2 and the one-way air outlet connector 3 are provided with a one-way air valve structure. Gas enters the bag body 1 through the one-way air inlet connector 2 and is then discharged from the one-way air outlet connector 3.

[0014] A first elastic element 4 is filled inside the bladder 1, and a second elastic element 5 is embedded inside the first elastic element 4. The stiffness coefficient of the second elastic element 5 is greater than that of the first elastic element 4. The second elastic element 5 ensures that the bladder 1 rebounds quickly, and the first elastic element 4 ensures that the bladder 1 has a full shape. The combination of the two can meet the airbag's inhalation and dehalation requirements.

[0015] Preferably, the first elastic element 4 is an elastic filler, which may be an elastic fabric, and the second elastic element 5 is a tower spring.

[0016] Furthermore, the elastic filler is a sponge, and vertical through holes adapted to the tower spring are provided on the elastic filler. The tower spring has a large compressibility, and its ultimate compression is close to the diameter of the tower spring wire, which can compress the bladder as much as possible and expel most of the gas in the bladder. The elastic filler fills the bladder, which can ensure that the bladder is full, reduce pits at the corners, and store as much gas as possible.
