Description

Technical Field

[0001] This utility model relates to the field of labor protection products, and in particular to a labor protection shoe with high breathability. Background Technology

[0002] Safety shoes, as an indispensable safety protection product in industrial production and daily life, are designed and manufactured with the needs of protecting the wearer's feet, improving work comfort, and adapting to diverse work environments in mind. Traditional safety shoes mostly use sturdy soles and upper materials to ensure effective protection of the feet under extreme conditions such as being crushed by heavy objects or punctured by sharp objects. However, with the increasing complexity of work environments and people's higher requirements for wearing experience, traditional safety shoes have gradually shown their shortcomings in terms of breathability, comfort, and lightweight.

[0003] In terms of breathability, traditional work shoes often prioritize protection while neglecting the importance of air circulation inside the shoe. This can lead to sweaty feet, unpleasant odors, and even foot skin diseases after prolonged wear. This not only affects the wearer's health but also reduces work efficiency and comfort. Utility Model Content

[0004] In order to solve the problems of breathability and comfort of traditional work shoes in the prior art, this utility model provides a work shoe with high breathability;

[0005] The present invention provides a highly breathable work shoe using the following technical solution:

[0006] A highly breathable work shoe includes a shoe body, a sole, a tongue, straps, and an upper. The sole is glued to the bottom of the shoe body. A tongue is sewn into the middle of the shoe body, and a strap for tightening the shoe body is attached to the upper side of the tongue. An upper is provided at the top of the shoe body for putting on and taking off. The sole has an internal ventilation structure that allows air to circulate inside the shoe body during walking.

[0007] Furthermore, the ventilation structure includes a front cavity and a rear cavity; the front cavity is located on the upper surface of the sole at the forefoot, and the rear cavity is located on the upper surface of the sole at the heel; an inner padding layer is bonded to the top of the sole, enclosing the front and rear cavities into a semi-closed structure; the inner padding layer is a breathable structure; at least two ventilation channels are provided between the front and rear cavities and inside the sole; the inner wall of the rear cavity has an exhaust port that penetrates the sole.

[0008] Furthermore, the inner diameter of the ventilation channel gradually decreases from the front cavity to the rear cavity;

[0009] Furthermore, the ventilation channel is arranged in a zigzag pattern, and the ventilation channel bends at least twice from the front cavity to the rear cavity;

[0010] Furthermore, the exhaust port is located at the upper edge of the sole away from the ground, and the exhaust port has a trumpet-shaped structure; the exhaust port gradually decreases in size from the inside of the rear cavity to the outer wall of the sole.

[0011] Furthermore, a sealing plate is provided at the opening near the outer side of the shoe sole for the exhaust port; two sealing plates are provided above and below the exhaust port and are alternately stacked; this is used to allow air inside the rear cavity to escape, but to restrict air from entering the outer side of the shoe sole.

[0012] Furthermore, the interior of the shoe body is also provided with a breathable mesh surface; the breathable mesh surface occupies at least one-third of the total area of ​​the shoe body;

[0013] Furthermore, the upper is a sponge structure wrapped in elastic fabric, which protects the ankle while providing elasticity and breathability.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] Addressing the issues of breathability and comfort in traditional work shoes, this invention significantly improves breathability by adding a ventilation structure that circulates and refreshes the air inside the shoe. The ventilation structure includes a front cavity, a rear cavity, and ventilation channels connecting them. When the wearer walks, the forefoot and heel alternately strike the ground, compressing the air in the front and rear cavities and allowing it to flow through the ventilation channels to the other cavity. Air in the rear cavity is then expelled from the sole through the exhaust port, while fresh air enters the shoe through the breathable mesh and upper, creating a continuous ventilation process. This design not only effectively solves the problem of poor breathability in traditional work shoes but also reduces foot dampness and odor.

[0016] Secondly, this invention also improves the comfort of the shoes; the breathable mesh surface increases the airflow inside the shoe body, further improving breathability; at the same time, the upper is made of elastic fabric wrapped with sponge structure, which not only protects the ankle, but also makes the upper elastic, which is conducive to breathability and adapts to different foot shapes; these detailed designs make the shoes fit the feet better, reducing pressure and discomfort.

[0024] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described in detail below:

[0025] This utility model discloses a work shoe with high breathability, such as... Figure 1 As shown, the shoe includes a shoe upper 1, a shoe sole 2, a shoe tongue 7, a strap 8, and a shoe upper 9. The shoe sole 2 is glued to the bottom of the shoe upper 1. The shoe tongue 7 is sewn into the middle of the shoe upper 1. A strap 8 for tightening the shoe upper 1 is attached to the upper side of the shoe tongue 7. The shoe upper 9 is provided at the top of the shoe upper 1 for putting on and taking off. The inside of the shoe sole 2 is provided with a ventilation structure that can circulate the air inside the shoe upper 1 during walking. In this embodiment, during walking, the forefoot and heel alternately hit the ground, compressing and expelling the air inside the shoe sole 2, and new air enters through the breathable mesh 6 and the shoe upper 9, thus achieving a continuous ventilation process.

[0026] like Figure 2 , 3As shown in Figures 4 and 5, the ventilation structure includes a front cavity 3 and a rear cavity 31. The front cavity 3 is located on the upper surface of the sole 2 at the forefoot, and the rear cavity 31 is located on the upper surface of the sole 2 at the heel. An inner padding layer 4 is bonded to the top of the sole, enclosing the front cavity 3 and the rear cavity 31 into a semi-closed cavity. The inner padding layer 4 is a breathable structure. At least two ventilation channels 32 are provided between the front cavity 3 and the rear cavity 31, which are located inside the sole 2. An exhaust port 33 penetrating the sole 2 is provided on the inner sidewall of the rear cavity 31. In this embodiment, the ventilation structure, by providing the front cavity 3 and the rear cavity 31 inside the sole 2, and the ventilation channels 32 connecting them, enables the air inside the shoe body 1 to be vented. The air circulation is achieved through the ventilation system. The forefoot cavity 3 and rearfoot cavity 31 are located on the upper surface of the sole 2 at the forefoot and heel, respectively. An inner padding layer 4 is bonded to the top of the sole, forming a semi-closed cavity around the forefoot cavity 3 and rearfoot cavity 31. During walking, the forefoot and heel alternately strike the ground, compressing the air in the forefoot cavity 3 and rearfoot cavity 31. Air in the forefoot cavity 3 flows through the ventilation channel 32 to the other cavity. Air in the rearfoot cavity 31 is expelled from the sole 2 through the exhaust port 33, while fresh air enters the shoe body 1 through the breathable mesh 6 and upper 9. This achieves air circulation within the shoe body 1, improving breathability, reducing foot dampness and odor, and enhancing wearing comfort.

[0027] like Figure 2 , 3 As shown in Figure 4, the inner diameter of the ventilation channel 32 gradually decreases from the front cavity 3 to the rear cavity 31; the ventilation channel 32 is arranged in a zigzag shape, and the ventilation channel 32 bends at least twice from the front cavity 3 to the rear cavity 31; in this embodiment, the gradually decreasing inner diameter and zigzag arrangement of the ventilation channel 32 help to control the speed of airflow; the gradually decreasing inner diameter of the ventilation channel 32 from the front cavity 3 to the rear cavity 31 makes it easy for the air in the front cavity 3 to flow into the rear cavity 31, but the air in the rear cavity 31 is difficult to be pressurized back into the front cavity 3 due to the inner diameter, and can only be discharged through the exhaust port 33, which facilitates gas exchange;

[0028] like Figure 5 , 6As shown, the exhaust port 33 is located at the upper edge of the sole 2 away from the ground, and the exhaust port 33 has a trumpet-shaped structure; the exhaust port 33 gradually decreases in size from the inside of the rear cavity 31 towards the outer wall of the sole 2; a sealing plate 5 is provided at the opening of the exhaust port 33 near the outer side of the sole 2; two sealing plates 5 are provided corresponding to the exhaust port 33, and are alternately stacked; this is used to allow air inside the rear cavity 31 to escape, but to restrict air from entering the outer side of the sole 2; in this embodiment, the design of the exhaust port 33 is intended to ensure that air inside the rear cavity 31 can be smoothly exhausted, while preventing air from entering the sole 2. Air from the outside enters; the exhaust port 33 is located at the upper edge of the sole 2 away from the ground, and has a trumpet-shaped structure, gradually decreasing in size from the inside of the rear cavity 31 towards the outer wall of the sole 2; a sealing piece 5 is provided at the opening of the exhaust port 33 near the outer side of the sole 2, and the upper and lower sealing pieces 5 are alternately stacked to allow air inside the rear cavity 31 to escape, but restrict the air from entering from the outside of the sole 2; this ensures that the air inside the rear cavity 31 can be smoothly discharged, improving the ventilation effect; and prevents air and debris from the outside of the sole 2 from entering the shoe, maintaining the cleanliness and breathability of the shoe;

[0029] like Figure 1 As shown, the interior of the shoe body 1 is also provided with a breathable mesh 6; the area occupied by the breathable mesh 6 is at least one-third of the total area of ​​the shoe body 1; in this embodiment, the breathable mesh 6 is located inside the shoe body 1, and its area is at least one-third of the total area of ​​the shoe body 1; when walking, air enters the interior of the shoe body 1 through the breathable mesh 6, and works together with the ventilation structure to realize the circulation of air inside the shoe body 1; significantly improving the breathability of the shoe and reducing the problems of foot dampness and odor;

[0030] like Figure 1 As shown, the upper 9 is a sponge-wrapped structure with elastic fabric, which protects the ankle while providing elasticity and breathability. In this embodiment, the upper 9 uses an elastic sponge-wrapped structure with elastic fabric, which protects the ankle and provides elasticity. When walking, the upper 9 can stretch and contract with the movement of the foot, maintaining a close fit to the foot. It provides sufficient support and protection, reducing the risk of ankle injury, increasing the breathability and comfort of the shoe, and improving the wearing experience.

[0031] The implementation principle of this utility model is as follows:

[0032] Forefoot landing phase:

[0033] When the wearer walks and the forefoot lands, the front cavity 3 of the sole 2 is compressed. After the air in the front cavity 3 is compressed, it will seek to flow to areas with lower pressure due to the increased pressure. At this time, the front cavity 3 and the rear cavity 31 are connected by a narrow and curved ventilation channel 32. Due to the pressure difference generated by the compression of the front cavity 3, the air will begin to flow to the rear cavity 31 through the ventilation channel 32. In this process, although the narrowness of the channel increases the flow resistance, it is precisely this resistance that makes the air speed up during the flow, further reducing the relative pressure in the channel.

[0034] Heel strike phase:

[0035] When the heel strikes the ground, the rear cavity 31 of the sole 2 is compressed. At this time, the air in the rear cavity 31 is also compressed, but due to the design of the ventilation channel 32, the air is difficult to flow back to the front cavity 3 quickly. The air in the rear cavity 31 is further compressed and squeezed towards the exhaust port 33. This causes most of the air in the rear cavity 31 to be discharged from the outside of the sole 2, forming a low-pressure area. This relatively low-pressure area forms a pressure difference with the pressure inside the shoe cavity, thereby attracting fresh air from the outside to enter the shoe through the shoe opening. The design of the upper 9 and the breathable mesh 6 of the shoe body 1 are conducive to the entry of air.

[0036] Continuous ventilation process:

[0037] During walking, the forefoot and heel alternately strike the ground, creating a continuous air exchange process. Each time the forefoot strikes the ground, some air flows from the front cavity 3 to the rear cavity 31 through the ventilation channel 32. Each time the heel strikes the ground, air is expelled at the exhaust port 33, thereby drawing fresh air into the shoe cavity. In this way, as walking continues, the air inside the shoe is constantly renewed and exchanged.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
