Description

Technical Field

[0001] This utility model relates to the field of footwear, specifically to a shoe sole that enhances breathability. Background Technology

[0002] Throughout the development of footwear products, sole design has always been a key factor influencing the wearing experience. With the improvement of people's quality of life and increased attention to sports and health, the requirements for sole function have become increasingly diversified, with breathability emerging as one of the important indicators for evaluating sole performance.

[0003] Traditional shoe sole designs have many shortcomings in terms of breathability. Early shoe soles were often simple in structure, only providing basic support and wear resistance. Air could not circulate effectively inside the shoe, causing heat and sweat generated by the feet during walking or exercise to be unable to escape in time. The inside of the shoe became hot and humid, which not only reduced wearing comfort but also easily fostered bacteria in the long term, leading to health problems such as foot odor and athlete's foot. Therefore, it is essential to develop a new shoe sole with enhanced breathability. Summary of the Invention

[0004] The purpose of this invention is to provide a shoe sole with enhanced breathability, which can improve breathability and achieve better gas exchange, thereby solving the existing technical defects and unmet technical requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shoe sole with enhanced breathability, comprising:

[0006] The sole body is connected to the shoe body and has several first through holes extending from the upper end face to the lower end face. Several first grooves and several second grooves are formed on the lower end face of the sole body. The several first through holes are connected to the openings formed on the lower end face of the sole body through the first grooves. One end of the second groove is connected to the first groove, and the other end extends to the side of the sole body. A one-way gas flow valve is provided in the second groove.

[0007] The outsole pad is connected to the lower end face of the main body of the sole.

[0008] In this application, one end of the second groove is located at the bottom of the sole body and communicates with the first groove. This portion of the second groove can also extend a section at the bottom of the sole body before connecting with the first groove. The other end of the second groove extends away from the bottom of the sole body, that is, it extends upwards a section before reaching the side of the sole body, forming an opening. The outsole pad covers the lower surface of the sole body and is sized to fit the sole body.

[0009] Preferably, the sole body is further provided with a recessed cavity, and the second groove communicates with the first groove connected to the first through hole through the recessed cavity.

[0010] In this application, the opening of the recessed cavity is located at the bottom of the sole body, and the recessed direction is upward. It should also be noted that in this application, the upward direction refers to the direction away from the ground when in use, and the downward direction refers to the direction closer to the ground.

[0011] Preferably, the bottom is further provided with a plurality of third grooves;

[0012] The upper surface of the outsole pad has several protrusions, which can be fitted into the third groove.

[0013] Preferably, the side of the sole body extends upward from the lower end of the sole body to above the upper end of the sole body, and the edge of the upper end of the sole body extends upward. The two extended portions converge to form a limiting portion and enclose an accommodating space above the upper end of the sole body.

[0014] In this application, it should be noted that "above" as mentioned above refers to the plane above the upper surface of the main body of the sole;

[0015] The above-mentioned limitations include at least three possible forms of display. However, when extending to the side, the width of the lower end of the sole body is used as a reference. The width refers to the distance between the two sides as seen from the heel direction, which can be understood as the width of the cross-section of the sole body. As mentioned above, the width of the lower end of the sole body is used as a reference. The shape formed during the extension of the two sides mentioned above must ensure that at least one point (one point on each side) makes the distance between the two sides (i.e., the width of the sole body) greater than the width of the lower end of the sole body. Therefore, the above-mentioned at least three forms of display are: The following description of the extension direction is from bottom to top (i.e., from the extension of the lower end of the sole body to the intersection).

[0016] The first type features curved sides. The two sides, when viewed in the cross-section of the sole, form two opposing elliptical curved edges. Specifically, the two sides first extend away from the center line of the cross-section of the sole, simultaneously extending upwards in an arc, and then extend towards the center line of the cross-section of the sole until they intersect. In summary, the overall shape resembles a single, protruding section.

[0017] The second type involves three parts in the extension process. First, it extends in a direction away from the center line of the cross-section of the sole body, and at the same time extends upward in an arc (the first protruding part). Then, it extends in a direction closer to the center line of the cross-section of the sole body to form a concave part. Then, it extends outward (away from the center line of the cross-section) to form the second protruding part. Finally, it extends inward (closer to the center line of the cross-section) to the intersection.

[0018] The third type extends in a similar way to the second type, except that the overall height of the main body of the sole is lower than that of the first and second types. So visually, although the third type also has two protruding parts, the first protruding part is more prominent than the second type, while the concave part and the second protruding part are not very obvious because the extension distance is limited.

[0019] Preferably, the two sides located along the length of the sole body extend obliquely upward, and their outlines at least form a protruding portion that extends horizontally beyond the edge of the sole body.

[0020] The main difference between the first type and the other two types is the number of protruding parts. The first type has only one protruding part, while the other two types have two. The main difference between the third type and the other two types is the overall height of the sole body. In addition, it needs to be further explained that the cross-section in the center line of the cross-section mentioned above refers to the cross-section that shows the width of the sole body mentioned earlier.

[0021] Preferably, the bottom of the outsole insole is provided with several spaced-apart abutment members for shock absorption and anti-slip purposes. (Material: rubber, with excellent wear resistance, elasticity, abrasion resistance, and not easily broken)

[0022] Preferably, the sole body is further provided with a second through hole, one end of which is opened on the side of the sole body and the other end is opened on the upper surface of the sole body.

[0023] Preferably, a buffer cavity is also provided on the lower end surface of the sole body. The buffer cavity is located between the second groove and the recessed cavity. One side of the recessed cavity is connected to the first through hole through the first groove, and the other side is connected to the buffer cavity through the first groove. The buffer cavity is connected to the second groove.

[0024] Preferably, the main body of the sole is divided into a forefoot area and a heel area;

[0025] The first through-hole is located in the forefoot area;

[0026] The second groove, recessed cavity, buffer cavity, and second through hole are distributed in the rear foot area.

[0027] In this application, it should be explained that the forefoot area refers to the part used to support the forefoot during use, and the heel area refers to the part used to support the heel during use. The thickness of the forefoot area is less than the thickness of the heel area.

[0028] Preferably, the abutment includes a first abutment and a second abutment, the first abutment and the second abutment being mirror-symmetrical in shape, the first abutment being located in the forefoot area and the second abutment being located in the rearfoot area.

[0029] Preferably, the front end of the lower surface of the sole body is tilted forward and upward, the rear end of the lower surface of the sole body is tilted backward and upward, and the rest of the lower surface is flat. That is, apart from the raised front and rear ends, the middle part is flat and has no significant indentation.

[0030] Compared with the prior art, the beneficial effects of this utility model are:

[0031] 1. In this embodiment, by setting the first through hole, the second through hole, the first groove and the second groove, and in combination with the setting of the fluid one-way flow valve, the ventilation effect can be achieved in multiple ways, while preventing dust and other debris from affecting the normal operation of each ventilation channel, so as to ensure the continuous maintenance of the ventilation effect.

[0032] 2. This application includes a buffer chamber and a recessed chamber, which can provide greater power to the gas during gas flow, that is, promote gas discharge by increasing pressure, further improve the gas discharge effect, and improve the efficiency of gas exchange.

[0033] 4. In this application, the arrangement of the first abutment and the second abutment enables the application to further increase the friction with the ground during use, and the way the two are arranged in opposite directions can further balance the stability of the contact with the ground when stepping on it.

[0034] 5. In this application, the combination of the protrusion and the third groove can increase the connection stability between the main body of the sole and the outer insole, and at the same time, it can realize the limiting function in the horizontal direction. Only when both appear can the sliding tendency be controlled and the impact on the connection stability of the two be reduced during use. Attached Figure Description

[0044] The following will refer to the appendix in the embodiments of this utility model. Figure 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0046] Please see Figure 1-8 Embodiments of this utility model: Example

[0047] like Figure 1-2 As shown: A breathable shoe sole includes:

[0048] The sole body 1 is connected to the shoe body and has several first through holes 2 extending from the upper end face to the lower end face. Several first grooves 3 and several second grooves 4 are formed on the lower end face of the sole body 1. The several first through holes 2 are connected to the openings formed on the lower end face of the sole body 1 through the first grooves 3. One end of the second groove 4 is connected to the first groove 3, and the other end extends to the side of the sole body 1. A one-way flow valve 5 is provided in the second groove 4.

[0049] The outer insole 6 is connected to the lower end face of the main body 1 of the sole.

[0050] In this embodiment, the gas unidirectional flow valve is specifically configured as a Tesla valve.

[0051] As shown in the figure: The main body 1 of the shoe sole is also provided with a recessed cavity 7, and the second groove 4 is connected to the first groove 3 with the first through hole 2 through the recessed cavity 7.

[0052] In this embodiment, the recessed cavity 7 is designed to store a large amount of air. When the foot lands, the recessed cavity 7 slightly deforms, increasing the efficiency of air expulsion and providing some power for smooth air release. Specifically, the connection relationship in this embodiment can be understood as follows: the first through-hole 2 connects to the mesh-like first groove 3, which in turn connects to the recessed cavity 7. There are three channels connecting to the recessed cavity 7. The first is the first groove 3 connected to the first through-hole 2; the second and third are also first grooves 3. However, the second and third first grooves 3 are used to connect the recessed cavity 7 to the second groove 4. That is, the first groove 3, acting as the second and third channels, is located between the second groove 4 and the recessed cavity 7, increasing the degree of gas delivery from the recessed cavity 7 to the buffer cavity 15. The end of the second groove 4 furthest from the third groove extends to the side of the sole body 1, forming an opening. For the buffer cavity 15, there are two... There is one air intake channel and one air outlet channel. Combined with the amount of air in the recessed cavity 7, the amount of gas discharged from the second groove 4 can be greatly increased, and the impact on the Tesla valve can be reduced. At the same time, the overall manufacturing cost can be reduced. It should be noted that this opening is located on the plane of the lower end face of the sole body 1, that is, at a certain distance from the lower end face of the sole body 1. The Tesla valve is installed at the above-mentioned opening and installed in the second groove 4, rather than installed on the lower end face of the second groove 4. This is because the second groove 4 can also be set to have an opening only on the lower end face of the sole body 1, instead of being set in the form of a groove, as long as it can be directly or indirectly connected to the recessed cavity 7 through the first groove 3.

[0053] like Figure 3 As shown: the bottom is also provided with several third grooves;

[0054] The upper surface of the outer insole 6 is provided with several protrusions, which can be fitted into the third groove.

[0055] In this embodiment, it should be further explained that the lower end face of the outsole pad 6 of this application has a fourth groove 9, which is concave upward, so that the upper end face of the outsole pad 6 has several protrusions. In addition, the number, position and size of the protrusions and the third groove are adapted to fit and install, which can increase the connection stability between the outsole pad 6 and the sole body 1, and has a limiting effect in the horizontal direction to prevent the two from sliding relative to each other. Of course, the setting of the protrusions and the third groove here increases the connection stability between the two, but it is not equivalent to the two being connected by the protrusions and the third groove. The connection between the two adopts the connection of the prior art, such as glue. Furthermore, it should be noted that only the uppermost part of the protrusion on the outsole pad 6 is above the lower end face of the sole body 1, and the other parts are all below the lower end face of the sole body 1, which will not affect the air circulation.

[0056] like Figure 4-6 As shown: The side of the sole body 1 extends upward from the lower end of the sole body 1 to above the upper end of the sole body 1. The edge of the upper end of the sole body 1 extends upward. The two extended parts meet together to form a limiting part 10, and form an accommodating space 11 above the upper end of the sole body 1.

[0057] In this embodiment, the limiting part 10 can be used to stably connect with the shoe body and can also limit the side of the foot to a certain extent, increasing the stability during use.

[0058] like Figure 4-6 As shown: the two sides located along the length of the sole body 1 extend obliquely upward, and their outlines at least form a protruding portion 12 that protrudes horizontally from the edge of the sole body 1.

[0059] In this embodiment, the two sides adopt the first extension method: the two sides are arc-shaped, and the two sides exhibit an elliptical shape on the cross-section of the sole body 1, with two oppositely arranged arc-shaped edges. That is, the two sides first extend away from the center line of the cross-section of the sole body 1, and at the same time extend upward in an arc, and then extend towards the center line of the cross-section of the sole body 1 to the intersection. In summary, the whole presents a protruding part 12.

[0060] like Figure 4-6 As shown: The bottom of the outer insole 6 of the shoe sole is provided with several spaced abutment members for shock absorption and anti-slip.

[0061] In this embodiment, the abutment is made of rubber, which has good wear resistance, elasticity, and is not easily broken.

[0062] The sole body 1 is also provided with a second through hole, one end of which is opened on the side of the sole body 1 and the other end is opened on the upper surface of the sole body 1.

[0063] In this embodiment, the second through hole can further increase air permeability. In this embodiment, the second through hole is made of TPU.

[0064] like Figure 2 As shown: A buffer cavity 15 is also provided on the lower end surface of the shoe sole body 1. The buffer cavity 15 is located between the second groove 4 and the recessed cavity 7. One side of the recessed cavity 7 is connected to the first through hole 2 through the first groove 3, and the other side is connected to the buffer cavity 15 through the first groove 3. The buffer cavity 15 is connected to the second groove 4.

[0065] In this embodiment, it should be noted that the volume of the buffer cavity 15 is much smaller than that of the recessed cavity 7. That is, in terms of both cross-section and depth, the buffer cavity 15 is smaller than the recessed groove. This is used to buffer the gas pressure in the recessed groove during use, and to prevent the excessive gas pressure in the second groove 4 from affecting the Tesla valve itself and the connection stability between the Tesla valve and the second groove 4.

[0066] like Figure 5 As shown: The main body of the sole 1 is divided into a forefoot area 16 and a heel area 17;

[0067] The first through hole 2 is located within the forefoot area 16;

[0068] The second groove 4, the recessed cavity 7, the buffer cavity 15, and the second through hole are distributed in the rear foot area 17.

[0069] The abutment includes a first abutment 18 and a second abutment 19, which are mirror images of each other in shape. The first abutment 18 is located in the forefoot area 16, and the second abutment 19 is located in the rear foot area.

[0070] like Figure 1 As shown: the front end of the lower surface of the main body 1 of the sole is inclined forward and upward, the rear end of the lower surface of the main body 1 of the sole is inclined backward and upward, and the rest of the lower surface is flat. That is, except for the raised front and rear ends, the middle part is flat and there is no obvious upward concavity.

[0071] Example 2: The difference between this example and Example 1 is that the extensions of the two sides of the sole body 1 are shaped on a cross section that shows the width of the sole body 1.

[0072] like Figure 7As shown: In this embodiment, the extension process includes three parts. First, it extends in a direction away from the center line of the cross-section of the sole body 1, and at the same time extends upward in an arc (first protrusion 12). Then it extends in a direction close to the center line of the cross-section of the sole body 1 to form a recessed part. Then it extends outward (away from the center line of the cross-section) to form a second protrusion 12. Then it extends inward (close to the center line of the cross-section) to the intersection.

[0073] Example 3: The difference between this example and Example 1 is that the extensions of the two sides of the sole body 1 are shaped on a cross section that shows the width of the sole body 1.

[0074] like Figure 8 As shown: In this embodiment, the extension process of the two sides is similar to that of embodiment 2, except that the overall height of the sole body 1 is lower than that of the sole body 1 in embodiments 1 and 2. Therefore, visually, although there are also two protruding parts 12 in this embodiment, the first protruding part 12 is more prominent than that in embodiment 2, while the recessed part and the second protruding part 12 are not very obvious because the extension distance is limited.

[0075] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0076] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
