Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and in particular to a breathable, antistatic, and cold-proof shoe. Background Technology

[0002] Shoes are essential for keeping people's feet warm, especially in low-temperature environments. Insufficient foot warmth can lead to poor blood circulation, frostbite, and other problems, directly affecting human comfort and work efficiency. In places with requirements for anti-static and cold protection, such as electronics workshops, laboratories, and precision instrument production workshops, special attention should be paid to whether the shoes worn meet the requirements.

[0003] Currently, some shoes use thick, non-breathable materials to ensure cold protection, which makes feet sweat easily, causing a stuffy feeling and poor comfort. In addition, the anti-static performance of these shoes is unstable, with large fluctuations in resistance value in dry environments, making it difficult to meet the stringent requirements of the precision electronics industry. This makes it difficult for existing anti-static and cold-proof shoes to balance breathability, anti-static properties, and cold protection, and thus cannot meet the needs of specific workplaces. Therefore, we provide a breathable, anti-static, and cold-proof shoe. Utility Model Content

[0004] This invention provides a breathable, antistatic, and cold-proof shoe to solve the technical problems existing in the background art.

[0005] The purpose and effect of this utility model of a breathable, antistatic, and cold-proof shoe are achieved by the following specific technical means: A breathable, antistatic, and cold-proof shoe includes a sole, which is composed of an antistatic rubber bottom layer and a cushioning and breathable layer. An upper is adhered to the top of the sole. A cold-proof layer is provided on the inner side of the upper. The cold-proof layer includes down cotton disposed on the inner side of the upper. An insole is placed on top of the sole. The insole includes a composite layer. An antistatic conductive wire is disposed at the bottom of the composite layer. An antistatic grounding component connected to the antistatic conductive wire is disposed at the heel of the sole.

[0006] Preferably, the material of the shoe upper is antistatic canvas.

[0007] Preferably, the outer side of the down cotton is provided with an inner protective layer, and the inner protective layer is made of breathable mesh fabric.

[0008] Preferably, the composite layer is composed of bamboo fiber cotton and activated carbon fiber.

[0009] Preferably, the antistatic grounding assembly consists of a conductive buckle and a conductive strip.

[0010] Beneficial effects:

[0011] 1. Features a cold-weather layer that blocks cold air from seeping in through gaps in the shoe upper, reducing heat exchange between the shoe and the outside environment and continuously locking in heat lost from the feet to keep them warm. 2. Features a cushioning and breathable layer that expels moisture from inside the shoe to the outside while drawing in fresh air, keeping the humidity inside the shoe within a comfortable range and achieving good ventilation.

[0012] 2. By using an anti-static grounding component in conjunction with an anti-static conductive wire, the anti-static conductive wire efficiently collects static electricity generated by foot contact and conducts it to the anti-static grounding component at the heel. The static electricity then accumulates here and is continuously released to the ground, thus completely preventing static electricity buildup. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] As attached Figure 1 Appendix Figure 2 With appendix Figure 3As shown: A breathable, antistatic, and cold-weather shoe includes a sole 1, which is composed of an antistatic rubber bottom layer 101 and a cushioning and breathable layer 102. The antistatic rubber bottom layer 101 contains partially conductive carbon black, forming a conductive path that can quickly conduct static electricity upon contact with the ground. Its hardness ensures the wear resistance and structural stability of the bottom layer. Furthermore, at the interface between the antistatic rubber bottom layer 101 and the cushioning and breathable layer 102, tiny channels corresponding to the ventilation holes on the cushioning and breathable layer 102 are reserved. These channels are solely for air circulation and are cushioned and breathable. The air layer 102 completely covers the entire structure, without affecting the structural integrity of the antistatic rubber bottom layer 101 or weakening its antistatic and wear-resistant properties. When the wearer walks, the foot exerts periodic pressure on the sole 1, squeezing the air inside the cushioning breathable layer 102, allowing moisture inside the shoe to be discharged downwards through the vents to the gaps in the antistatic rubber bottom layer 101. When the foot is lifted, the cushioning breathable layer 102 rebounds, and due to negative pressure, it draws in fresh air from the outside, which is then replenished upwards through the vents to the inside of the shoe, ensuring good breathability and keeping the humidity inside the shoe within a comfortable range.

[0022] As attached Figure 1 With appendix Figure 2 As shown: The upper 2 is bonded to the top of the sole 1. The material of the upper 2 is antistatic canvas. The antistatic canvas used in the upper 2 is based on polyester yarn, with some carbon fiber yarn mixed in both the warp and weft yarns. It is made by plain weave process, with a thickness of 0.3-0.5mm. The surface resistance value is stable within a suitable range. It can conduct static electricity from the human body through carbon fiber yarn, and block external dust with its dense weave structure. At the same time, it has a certain tear resistance to meet the wear resistance requirements during workshop operation.

[0023] As attached Figure 1 Appendix Figure 2 With appendix Figure 4 As shown: The inner side of the shoe upper 2 is provided with a cold-proof layer 3, which includes down cotton 301 set on the inner side of the shoe upper 2. The down cotton 301 completely covers the entire corresponding area of ​​the foot from the front of the shoe to the back of the heel on the inner side of the shoe upper 2, with a thickness of 5-8mm. It can form a thick warm barrier, which can effectively block the cold air from entering through the gaps of the shoe upper 2, and reduce the heat exchange between the inside of the shoe and the outside through the shoe upper 2, continuously locking in the heat emitted by the foot and keeping the foot warm. The outer side of the down cotton 301 is provided with an inner protective layer 302. The inner protective layer 302 is made of breathable mesh fabric. The inner protective layer 302 completely covers the outer surface of the down cotton 301, which can ensure good breathability and effectively prevent the down of the down cotton 301 from leaking out, further improving the balance between warmth and breathability, while avoiding discomfort caused by the foot directly contacting the down cotton 301.

[0024] As attached Figure 1 Appendix Figure 2 With appendix Figure 5 As shown: An insole 5 is placed on top of the sole 1. The insole 5 includes a composite layer 501, which is made of bamboo fiber cotton and activated carbon fiber. The bamboo fiber cotton is on the top layer, which has good moisture absorption and breathability and can quickly absorb foot sweat. The activated carbon fiber is on the bottom layer, which can effectively absorb odors inside the shoe. The two layers are bonded together by a needle-punching process, making them difficult to separate. This retains the softness and comfort of the bamboo fiber cotton while leveraging the purification function of the activated carbon fiber, thus improving the overall practicality of the insole 5. An antistatic conductive wire 502 is set at the bottom of the composite layer 501. The antistatic conductive wire 502 efficiently collects static electricity generated by foot contact. The heel of the sole 1 is equipped with an antistatic conductive wire 502. The antistatic grounding component 4 is connected to the electrostatic conductive wire 502. The antistatic grounding component 4 consists of a conductive buckle and a conductive strip. The conductive buckle is set at the heel. One end of the conductive strip is connected to the conductive buckle, and the other end extends along the inner edge of the antistatic rubber bottom layer 101 to the front end of the sole 1 and is fixed to the inner part of the front end of the sole 1. The antistatic conductive wire 502 extends downward from the exposed end at the heel of the insole 5, passes through the reserved channel inside the cushioning and breathable layer 102, and is bonded to the upper surface of the conductive buckle with conductive adhesive to form a low-resistance path. This allows the static electricity generated by the foot to be quickly conducted to the front end of the sole 1 and released in sequence through the antistatic conductive wire 502, the conductive buckle, and the conductive strip, further ensuring the antistatic effect.

[0025] Working principle: When wearing these breathable, antistatic, and cold-weather shoes, the carbon fiber in the antistatic canvas of the upper 2 can quickly capture static electricity generated by the human body. This static electricity converges towards the heel through the conductive path formed by the warp and weft threads of the canvas. The down cotton 301 in the cold-weather layer 3 forms a sealed air layer with its fluffy fiber structure. It can effectively block cold air from entering through the gaps in the upper 2, and reduce the heat exchange between the inside of the shoe and the outside through the upper 2, continuously locking in the heat dissipated by the feet and keeping them warm. At the same time, the antistatic conductive wires 502 distributed in a grid pattern on the bottom of the insole 5 will efficiently collect the static electricity generated by the foot contact and conduct the static electricity to the antistatic layer at the heel. The conductive buckle on the electrostatic grounding component 4 allows static electricity to accumulate and then be continuously released to the ground via the conductive strip connected to the buckle, completely preventing static electricity accumulation. In addition, the cushioning and breathable layer 102 of the sole 1 has a large number of ventilation holes. When the wearer walks, the foot exerts periodic pressure on the sole 1, squeezing the air inside the cushioning and breathable layer 102, causing the moisture inside the shoe to be discharged downward through the ventilation holes to the gaps in the antistatic rubber bottom layer 101. When the foot is lifted, the cushioning and breathable layer 102 rebounds, and the negative pressure draws in fresh air from the outside, which is then replenished to the inside of the shoe through the ventilation holes, keeping the humidity inside the shoe within a comfortable range, thus achieving a synergistic effect of warmth, antistatic properties, and breathability.
