Problems solved by technology

[0005] However, the disadvantage of the prior art is that when walking on the wetland with agricultural shoes, the feet and shoes will inevitably be trapped in the wetland and it is difficult to walk. Walking is very slow and inconvenient, which greatly reduces the working efficiency, and if there is an emergency, the personnel may not be able to avoid it. Therefore, it is necessary to provide a kind of footwear that is convenient for walking in wetlands, so as to improve the working efficiency of personnel in rainy days and protect personnel. Safety

Embodiment Construction

[0039] The implementation of the present invention will be described in more detail in conjunction with the drawings and component symbols below, so that those skilled in the art can implement it after studying this specification.

[0040] When walking on wet ground with footwear, it is inevitable that the feet and shoes will be trapped in the wet ground and it is difficult to walk. It takes a lot of effort to pull the feet and shoes out of the wet ground, which will cause this phenomenon. Because, when the shoes fall into the wetland, because the shoes are completely immersed in the wetland, the wetland will block the air outside. Unable to enter, a vacuum space will naturally be formed. Since the atmospheric pressure outside the wetland is greater than the vacuum pressure inside the wetland, the feet and shoes will be trapped in the wetland and it is difficult to extricate themselves. Therefore, the present invention provides a vacuum-breaking structure of the shoe body that...

Abstract

The invention relates to a vacuum breaker structure of footwear. The vacuum breaker structure comprises a shoe and a shoe barrel. The shoe is provided with a sole, the shoe barrel is connected onto the shoe, the sole is provided with a discharge hole and a check valve, the check valve is provided with an inlet and an outlet, the inlet is connected with a guide pipe, fluid can be guided into the inlet by the aid of the guide pipe, the outlet is communicated with the discharge hole, and the check valve only permits the fluid to flow from the inlet to the outlet. The vacuum breaker structure has the advantages that when the outlet is in a vacuum state, the pressure on an outlet side of the footwear can be lower than the pressure on an inlet side of the footwear, the fluid is driven to flow out of the outlet, and the vacuum state of the outlet side of the footwear is terminated, so that vacuum space formed in a wetland when the footwear is sunken in the wetland can be effectively eliminated, and the footwear is easy to pull out of the wetland.

Description

technical field [0001] The present invention relates to a kind of footwear, especially a kind of footwear which can release the vacuum state in the wetland. Background technique [0002] Shoes are a kind of article worn on the feet. They have the functions of keeping warm, protecting the feet, and preventing wear and tear on the soles of the feet. Shoes are divided into various categories according to the functions used, such as leather shoes and high-heeled shoes worn on formal occasions, and home furnishings. Shoes, casual shoes for casual outings, sports shoes for sports, hiking shoes for mountain climbing, and rain boots for rainy days. [0003] Among them, the rain boots have a unique waterproof effect because of their integrally formed airtight space shape, and the general farmland, construction site workers, housewives who clean up the house, or people will wear rain boots to facilitate their work when it rains. [0004] Please refer to the agricultural boots of the ...
