Problems solved by technology

But there are following deficiencies: one is that the front side of the outsole is provided with air vents, and the disc spring that plays the role of the air circulation pressurized pump is at the rear of the inner sole of the shoe as the air intake and outlet of the air circulation. The air holes are all located on the side of the sole, and the distance between the two cannot form a powerful aerodynamic source; the second is that there are no vent holes on the upper end of the disc spring, so it is impossible to make the air circulation system start from the source; the third is because the disc spring The position of the shaped spring in the shoe is the heel of the shoe, which requires strong toughness and elasticity. The choice of metal material can meet its performance, but it is easy to get wet and rust, which will affect the function and function of the air pump, cause failure and affect the service life of the product. Therefore improving the deficiencies of the prior art and providing air-conditioning shoes with excellent performance to meet people's needs is a problem to be solved urgently by those skilled in the art

Embodiment 1

[0028] The pump drum of embodiment 1 of the present invention (referring to figure 1 , figure 2 , image 3 ), it is designed to meet the technical requirements that the flow volume of the air circulation system is not too large, the impact resistance of the pump drum at the heel of the insole is average, and it can bounce back and walk in the design and processing process of men's and women's air-conditioned fashion shoes. . It is composed of a complete U-shaped whole. The outer surface of the pump drum is an arc 1 of the entire arc structure, and the central line is a raised arc 2 in the middle. Circular air hole 3, skirt 4 is provided around the U-shaped arc surface of the pump drum, the bottom surface of skirt 4 is an overall planar structure, and the top of skirt 4 is a continuation of arc 1. The pump drum in Example 1 of the present invention is injection-molded in a mould, using a thermoplastic polyurethane elastomer material with high strength, high toughness, stron...

Embodiment 2

[0030] The pump drum of embodiment 2 of the present invention (referring to Figure 4 , Figure 5 , Image 6 ), it is suitable for men and women air-conditioned casual shoes, air-conditioned travel shoes and high-end air-conditioned shoes. The sole has a strong compressed gas and promotes a large air flow. designed for technical requirements. Except that the technical solution described in this embodiment is the same as the technical solution of the above-mentioned embodiment 1, the differences mainly include the following points: one is that the curved surface 2 of the middle bulge is a structural form with a high back and a low front, That is, the U-shaped notch end of the U-shaped pump drum is the front end. The purpose is to ensure that the air-conditioned casual shoes and air-conditioned travel shoes have greater exercise volume and impact than air-conditioned fashion shoes when the wearer wears and exercises. In order to ensure that the arch of the wearer's foot is be...

Embodiment 3

[0032] The pump drum of embodiment 3 of the present invention (referring to Figure 7 , Figure 8 , Figure 9), it is to meet the needs of air-conditioned sports shoes with powerful compressed gas function, and to achieve sufficient air flow, so that heat can be dissipated quickly during exercise, and at the same time to achieve air-conditioned sports shoes with extremely high load-bearing capacity, excellent resistance to impact and light It is designed according to the technical requirements of seismic performance. Except that the technical solution described in this embodiment is the same as the technical solution of the above-mentioned embodiment 1, the differences mainly include the following points: one is that the curved surface 2 of the middle bulge is a structural form with a low front and a high rear, The U-shaped notch end of the U-shaped pump drum is the front end. Its purpose is to ensure that when the wearer is exercising, a large amount of exercise will have a...

Abstract

The invention relates to a pump drum and application thereof and belongs to the technical field of shoemaking. The pump drum has a U-shaped cambered surface structure of which the middle is protruded; the periphery is provided with a skirt; the middle protruded back is provided with at least one air hole; and the pump drum is used for making compressed gas for air conditioning shoes. Compared with the prior art, the pump drum has the substantial characteristics of reasonable and scientific structural design and proper materials, and the application of the pump drum in the air conditioning shoes achieves the effects of smooth air circulation and dry air in the air conditioning shoes and user walking resistance through rebounding, and can achieve remarkable progress of relieving foot fatigue, reducing foot injury and the like particularly.

Description

technical field [0001] The invention relates to the technical field of shoemaking, in particular to a pump drum and its application in built-in air-conditioning shoes. Background technique [0002] With the continuous improvement of people's living standards and the growth of material and cultural needs, social consumption needs are also constantly changing. Taking shoes as an example of the necessities of human life, the standard of its demand has also developed from elegant appearance, pure texture, and durability to high-end, brand, comfort, environmental protection, and health care. In order to meet the market demand, many manufacturers have brought to the market various footwear products with health care functions produced and processed by themselves, among which various air-conditioning shoes are an example. As far as the technical field of air-conditioning shoes is concerned, how to satisfy the functions of air-conditioning shoes in a broad sense, from the current ex...
