Description

Technical Field

[0001] The utility model belongs to the field of shoes, in particular to a sole ventilation device and a sole. Background Art

[0002] Traditional waterproof respirators, including soles and uppers, are typically equipped with exhaust modules, such as airbags, to remove contaminated air from the shoe cavity. However, the airbags in these respirator shoes take up a significant amount of space on the sole, making them unsuitable for use in shoes with thinner soles. To accommodate the ventilation of soles of varying thicknesses, application number 201721752381.4 discloses a shoe respirator and a mold for manufacturing the same. This involves fixing a waterproof, breathable membrane between the upper and lower portions of the respirator. During injection molding, the membrane must first be placed in the mold and then secured by injection molding the upper and lower portions. This creates significant production difficulties and low processing efficiency. Furthermore, directly fixing the edge of the shoe respirator body to the sole can easily cause it to fall off during use, impacting the shoe's service life. Utility Model Content

[0003] The purpose of the present utility model is to provide a sole ventilation device and a sole that can solve at least one of the above problems.

[0004] According to one aspect of the utility model, a sole ventilation device is provided, including a support block and a waterproof breathable membrane. The support block cooperates with the bottom of the sole. A boss is provided on the inner side of the support block, and a breathable hole is provided on the boss. The breathable hole passes through the support block. The waterproof breathable membrane is fixed on the upper end surface of the boss and is arranged corresponding to the breathable hole.

[0005] The beneficial effects of the utility model are as follows: by providing the support block, the entire block is conveniently fixed to the bottom of the sole, the contact and fixing area of ​​the entire sole ventilation device and the sole can be increased, thereby improving the stability of the entire fixation on the sole, preventing the entire block from easily falling off the sole, and ensuring the service life; by providing the boss, it is convenient to cooperate with the sole, and the gas in the shoe is conveniently connected to the outside through the ventilation holes on the boss, thereby achieving a ventilation effect; by fixing the waterproof and breathable membrane on the upper end surface of the boss, there is no need to put the waterproof and breathable membrane into the injection mold for injection molding and fixing, thereby facilitating the molding of the entire support block, greatly reducing the production difficulty, reducing the production cost, and helping to improve processing efficiency.

[0006] In some embodiments, the left and right ends of the support block are provided with side wings, and the side wings and the bosses are both located on the inner side of the support block. Thus, the side wings facilitate the cooperation with the side surfaces of the sole, facilitate the fit with the sole, and improve the stability of the overall fixation with the sole.

[0007] In some embodiments, the support block, boss, and wing are integrally formed, thereby facilitating rapid processing and molding of the entire structure.

[0008] In some embodiments, the boss is tilted so that the height of the rear end of the boss is greater than the height of the front end. Thus, the boss can be arranged to conform to the thickness variation of the arch of the sole, ensuring the comfort of the sole when wearing it.

[0009] In some embodiments, a first reinforcing rib is provided on the outer side of the support block, and the first reinforcing rib is located at the periphery of the air vent. Thus, by providing the first reinforcing rib, the strength of the entire outer side of the air vent can be improved.

[0010] In some embodiments, the outer side of the support block is provided with multiple ridges, which extend from the support block to the corresponding side wings. Thus, the provision of ridges can improve the strength of the transition between the support block and the side wings, maintain the corresponding shape, and improve the aesthetics.

[0011] In some embodiments, a second reinforcing rib is provided on the periphery of the ridge, thereby ensuring the strength of the side wing and helping the side wing to maintain a corresponding shape.

[0012] According to another aspect of the present invention, a shoe sole is provided, comprising the aforementioned sole ventilation device, and further comprising a body, wherein the body is provided with a mounting hole, the mounting hole extending through the body from top to bottom, the boss engaging with the mounting hole, the support block affixing to the bottom end of the body, and the waterproof breathable membrane extending through the mounting hole. Thus, the provision of the mounting hole in the body facilitates engagement with the boss, thereby facilitating positioning of the waterproof breathable membrane on the inner side of the sole, thereby achieving excellent waterproof and breathable effects.

[0013] In some embodiments, a sunken groove is provided at the upper end of the shoe body, with the mounting hole located at the bottom of the groove. The upper end surface of the waterproof, breathable membrane is lower than the upper end surface of the groove. Thus, the presence of the sunken groove prevents the sole of the user from pressing against the waterproof, breathable membrane, allowing air inside the shoe to pass through the membrane and then connect to the outside world through the vents, ensuring excellent ventilation.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1 to 5 The sole ventilation device includes a support block 1 and a waterproof breathable membrane 2. The support block 1 cooperates with the bottom of the sole. A boss 3 is provided on the inner side of the support block 1. The boss 3 is provided with an air hole 31. The air hole 31 passes through the support block 1. The waterproof breathable membrane 2 is fixed to the upper end surface of the boss 3 and is arranged corresponding to the air hole 31. That is, when the sole ventilation device is in use, the air in the shoe can pass through the waterproof breathable membrane 2 and then be discharged through the air hole 31 to achieve a ventilation function. Among them, the waterproof breathable membrane 2 is fixed to the boss 3 by bonding, and plays a good waterproof and breathable function. In order to improve the anti-puncture and anti-slag functions of the waterproof breathable membrane 2, a trace amount of metal wire can be added to the molding material of the waterproof breathable membrane 2. The material of the waterproof breathable membrane 2 is the existing technology and will not be described here.

[0021] The left and right ends of the support block 1 are provided with side wings 4 , and the side wings 4 and the boss 3 are both located on the inner side of the support block 1 .

[0022] The support block 1, the boss 3 and the side wings 4 are an integral injection-molded structure.

[0023] The boss 3 is tilted, with the rear end of the boss 3 being higher than the front end. Thus, when mounted on a shoe sole, the boss 3 can maintain the same inclination as the arch of the shoe sole, thereby ensuring comfort when the shoe sole is worn after the boss 3 is mounted.

[0024] The outer side of the support block 1 is provided with a first reinforcing rib 11, which is located around the vent hole 31. The first reinforcing rib 11 protrudes from the outer end surface of the support block 1 and increases the strength around the vent hole 31, reducing deformation at the vent hole 31 and ensuring ventilation of the vent hole 31.

[0025] The outer side of the support block 1 is provided with ridges 12, which are multiple and extend from the support block 1 to the corresponding side wings 4. Thus, the ridges 12 facilitate the shaping of the side wings 4 toward the support block 1 and improve the overall aesthetics.

[0026] A second reinforcing rib 13 is provided on the outer periphery of the ridge 12 .

[0027] The first reinforcing rib 11 , the second reinforcing rib 13 and the ridge 12 are all integrally formed with the support block 1 through injection molding, thereby improving the integrity of the entire support block 1 .

[0028] The sole of the present invention includes the above-mentioned sole ventilation device 10, and also includes a body 5. The body 5 is provided with a mounting hole 51, which passes through the body 5 from top to bottom. The boss 3 cooperates with the mounting hole 51, the support block 1 fits with the bottom end of the body 5, and the waterproof breathable membrane 2 extends after passing through the mounting hole 51.

[0029] During actual assembly, after the waterproof breathable membrane 2 is glued and fixed to the boss 3, the boss 3 is aligned with the mounting hole 51 and snapped into the mounting hole 51, so that the waterproof breathable membrane 2 is located on the inner side of the body 5 and the outer wall of the boss 3 is in close contact with the inner wall of the mounting hole 51. The inner side of the support block 1 is closely attached to the bottom end of the body 5, and the side wings 4 on both sides are glued and fixed to the side surfaces of the body 5. Therefore, under the action of the support block 1 and the side wings 4, the corresponding positions of the body 5 can be covered to a certain extent, so that the entire sole ventilation device 10 can be tightly fixed to the outside of the body 5.

[0030] When the sole is in use, air on the sole of the foot can flow to the outside through the waterproof breathable membrane 2 and the air holes 31, and the outside air can enter the shoe through the air holes 31 and the waterproof breathable membrane 2, thereby achieving a breathable effect for the shoe and meeting corresponding usage requirements.

[0031] A sunken groove 52 is formed at the upper end of the body 5, with the mounting hole 51 located at the bottom of the groove 52. The upper end surface of the waterproof breathable membrane 2 is lower than the upper end surface of the groove 52. In actual use, the upper end surface of the groove 52 can be 1-2 mm higher than the waterproof breathable membrane 2. This prevents the sole of the user's foot from coming into contact with the waterproof breathable membrane 2 when wearing shoes, ensuring a certain gap between the waterproof breathable membrane 2 and the sole of the foot, thereby enhancing the ventilation effect of the waterproof breathable membrane 2 and the air permeability holes 31.

[0032] The above are only preferred embodiments of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
