Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and more specifically, to a breathable, cool-feeling shoe. Background Technology

[0002] Traditional sandals have long faced technological bottlenecks in terms of breathability and functionality. Conventional sandal designs often rely on perforations or mesh materials in the upper for basic ventilation. However, this passive ventilation structure is limited by environmental airflow conditions, and its heat dissipation effect significantly decreases in static or low-wind-speed environments, leading to stuffy and damp feet. Current technologies generally use rigid supports or single-density materials for shoe support, which, while providing basic support, severely hinders natural heat dissipation from the feet and can easily cause arch fatigue with prolonged wear. Some improvement solutions attempt to introduce ventilation holes or airflow channels, but lack dynamic adjustment mechanisms, failing to adapt to the breathability needs under different environmental temperatures or exercise intensities.

[0003] In terms of heat dissipation system design, traditional solutions mostly adopt unidirectional ventilation structures, relying on the temperature difference between the inside and outside of the shoe for passive airflow. Their heat exchange efficiency is limited by the thermal conductivity of the materials and cannot actively accelerate heat dissipation. Furthermore, the sole heat dissipation design generally suffers from a lack of structural simplicity; static heat dissipation channels are easily deformed and blocked by foot pressure during walking, leading to a significant reduction in heat dissipation efficiency. Existing adjustable ventilation devices mostly use simple opening and closing structures, with low adjustment precision and a lack of positioning and holding functions, making them prone to unexpected changes in ventilation status due to movement and vibration.

[0004] More importantly, the breathability, support, and heat dissipation functions of existing sandals are mostly independent modules, lacking systematic integration. The rigid materials of the support structure hinder airflow, while the design of the heat dissipation channels often ignores the biomechanical characteristics of the foot, making it difficult to achieve both efficient heat dissipation and comfortable wear during walking. These technical deficiencies make it difficult for traditional sandals to meet the comprehensive needs of modern consumers for all-weather breathability, adaptive adjustment, and long-lasting comfort. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a breathable and cool shoe that can achieve stepless adjustment through a rotatable breathable adjustment ring with magnetic positioning. Users can precisely control the ventilation in the heel area according to the ambient temperature or exercise intensity, taking into account both breathability and wind and dust protection needs.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A breathable, cool shoe includes a shoe body, an upper, and a composite sole. An elastic support frame is fixedly connected to the upper part of the shoe body to support the upper. The upper is made of elastic mesh fabric. A ventilation hole is provided at the heel of the shoe body, and a matching rotatable ventilation adjustment ring is embedded in the ventilation hole.

[0010] Furthermore, the elastic support frame includes an arc-shaped frame with multiple evenly distributed conical vent holes. A waterproof and breathable membrane is fixedly connected to the upper end face of each conical vent hole. The conical vent holes allow airflow interaction between the internal environment and the external environment, while the waterproof and breathable membrane allows gas to pass through but prevents moisture from entering.

[0011] Furthermore, the composite sole includes an integrated insole and a bottom insole, which are formed by bonding upper and lower parts together. The integrated insole has a heat dissipation channel in the horizontal direction, which extends from the forefoot to the heel. The heat dissipation channel can quickly ventilate and dissipate heat from the foot, so that the heat accumulated on the sole can be dissipated to a certain extent.

[0012] Furthermore, a wave-shaped elastic support membrane is provided inside the heat dissipation channel. The elastic support membrane has micropores aligned with each other. On the one hand, the elastic support membrane can improve the elasticity of the one-piece insole and improve the foot feel. On the other hand, when walking, the elastic support membrane can be indirectly squeezed and deformed to squeeze out the gas in the heat dissipation channel, thereby forming gas flow and accelerating heat dissipation.

[0013] Furthermore, the rotatable ventilation adjustment ring includes a ventilation cylinder with multiple evenly distributed fan-shaped ventilation holes at its inner end. A rotating column is rotatably installed at the center of the ventilation cylinder, and multiple fan-shaped adjustment plates matching the fan-shaped ventilation holes are fixedly installed at the outer end of the rotating column. The fan-shaped ventilation holes are connected to each other, allowing the heel to communicate with the external environment. Users can adjust the ventilation area by rotating the rotating column to allow the fan-shaped adjustment plates and fan-shaped ventilation holes to work together, thereby achieving ventilation adjustment.

[0014] Furthermore, an annular magnetic layer is fixedly connected to the inner wall of the ventilator, and a magnetic block that magnetically attracts the annular magnetic layer is fixedly connected to the outer end of the fan-shaped adjustment plate. Through the magnetic attraction between the magnetic block and the annular magnetic layer, it is convenient for the user to rotate the rotating column at any angle, and it is not easy for it to rotate on its own due to external force.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) The rotating breathable adjustment ring of this solution can be infinitely adjusted by magnetic positioning. Users can accurately control the ventilation volume of the heel area according to the ambient temperature or exercise intensity, taking into account both breathability and windproof and dustproof requirements.

[0018] (2) The conical channels of the elastic support frame and the waterproof and breathable membrane form a vertical airflow path, and the wave-shaped membrane of the composite sole constructs a horizontal heat dissipation channel. The two are orthogonally superimposed to form a three-dimensional ventilation network, which significantly improves the heat dissipation efficiency in static and dynamic states.

[0019] (3) The arc-shaped structure of the elastic support skeleton of this solution fits the physiological curve of the foot arch and disperses the pressure on the sole of the foot; the dual-density layered design of the composite sole ensures support while absorbing impact energy through the deformation of the elastic diaphragm, reducing walking fatigue.

[0031] Example 1:

[0032] Please see Figure 1-6 A breathable and cool shoe includes a shoe body 1, a shoe upper 2 and a composite sole 3. The shoe body 1 is characterized by having an elastic support frame 4 fixedly connected to the upper end to support the shoe upper 2. The shoe upper 2 is made of elastic mesh fabric. A ventilation hole is provided at the heel of the shoe body 1, and a matching rotatable ventilation adjustment ring 5 is embedded in the ventilation hole.

[0033] The elastic support frame 4 includes an arc-shaped frame 401, on which a plurality of evenly distributed conical vent holes 402 are provided. A waterproof and breathable membrane 403 is fixedly connected to the upper end face of the conical vent holes 402. The conical vent holes 402 allow airflow interaction between the internal environment and the outside environment, while the waterproof and breathable membrane 403 allows gas to pass through while preventing moisture from entering.

[0034] The elastic support frame 4's arc-shaped frame 401 is injection molded from high-toughness TPU material, with a Shore hardness of 65±3D and a thickness of 1.5-2mm. Its curvature matches the physiological curve of the foot arch. The conical ventilation holes 402 are radially distributed, with a large end diameter of 4mm, a small end diameter of 1.5mm, a cone angle of 15°, and a hole spacing of 8-10mm. The waterproof and breathable membrane 403 is made of expanded polytetrafluoroethylene (ePTFE), with a thickness of 0.1mm, a pore size of 0.5-1μm, and an air permeability ≥8000g / m³. 2 • 24h, water pressure resistance ≥10kPa. This structure guides hot air from the feet upwards through conical channels, while using a waterproof membrane to prevent external liquid water from penetrating.

[0035] The composite sole 3 includes an integrated insole 301 and a bottom insole 302, which are formed by bonding the upper and lower parts together. The integrated insole 301 has a heat dissipation channel 303 in the horizontal direction, which extends from the forefoot to the heel. The heat dissipation channel 303 can quickly ventilate and dissipate heat for the foot, so that the heat accumulated on the sole can be dissipated to a certain extent.

[0036] A wave-shaped elastic support membrane 304 is provided inside the heat dissipation channel 303. The elastic support membrane 304 has micropores aligned with each other. On the one hand, the elastic support membrane 304 can improve the elasticity of the one-piece insole 301 and improve the foot feel. On the other hand, when walking, the elastic support membrane 304 can be indirectly squeezed and deformed to squeeze out the gas in the heat dissipation channel 303, thereby forming gas flow and accelerating heat dissipation.

[0037] The integrated insole 301 uses dual-density EVA foam material, with an open-cell structure on the upper layer (hardness 40 Shore C) and a closed-cell structure on the lower layer (hardness 55 Shore C). The heat dissipation channel 303 has a trapezoidal cross-section, with a top width of 6mm, a bottom width of 10mm, and a depth of 4mm. The inner wall of the channel is coated with a graphene thermally conductive coating. The elastic support diaphragm 304 is made of silicone, 0.8mm thick, with a wavy peak spacing of 5mm, a trough depth of 2mm, and micropores with a diameter of 0.3mm, arranged in a staggered pattern. When the diaphragm is compressed and deformed, it generates a pumping effect, driving the directional flow of air within the channel.

[0038] The rotatable ventilation adjustment ring 5 includes a ventilation cylinder 501. The inner end of the ventilation cylinder 501 has multiple evenly distributed fan-shaped ventilation holes 502. A rotating column 503 is rotatably installed at the center of the ventilation cylinder 501. Multiple fan-shaped adjustment plates 504 that match the fan-shaped ventilation holes 502 are fixedly installed at the outer end of the rotating column 503. The fan-shaped ventilation holes 502 are connected to the ventilation holes so that the heel can be connected to the external environment. The user can adjust the ventilation area by rotating the rotating column 503 so that the fan-shaped adjustment plates 504 and the fan-shaped ventilation holes 502 can cooperate.

[0039] An annular magnetic layer 506 is fixedly connected to the inner wall of the vent 501. A magnetic block 505 that magnetically attracts the annular magnetic layer 506 is fixedly connected to the outer end of the fan-shaped adjusting plate 504. Through the magnetic attraction between the magnetic block 505 and the annular magnetic layer 506, it is convenient for the user to rotate the rotating column 503 at any angle, and it is not easy for it to rotate on its own due to external force.

[0040] The vent 501 is made of nylon 66, with an inner diameter of 12mm and a wall thickness of 1.2mm. The fan-shaped vent 502 has a central angle of 45°, a radial length of 10mm, and is evenly distributed in four groups around the circumference. The rotating column 503 is a 304 stainless steel shaft with a diameter of 5mm, and a PTFE bearing is installed between it and the vent 501. The fan-shaped adjusting plate 504 is made of flexible rubber with a thickness of 1mm, and the magnetic block 505 is a N35 grade neodymium iron boron magnet with dimensions of 3×3×1mm. The annular magnetic layer 506 is a rubber magnetic strip with a pole spacing of 1mm, and the magnetic attraction force with the adjusting plate is ≥0.5N. During rotational adjustment, the magnetic attraction provides a segmented feel and prevents displacement.

[0041] Working principle:

[0042] When worn, foot heat radiates outward through the elastic mesh upper 2, while foot heat is conducted through the heat dissipation channel 303 of the integrated insole 301. During walking, foot pressure periodically acts on the elastic support diaphragm 304. When its wave-shaped structure is deformed under pressure, it forces air in the channel to flow from the heel to the forefoot. When the deformation recovers, it draws in external cool air through micropores, forming a reciprocating airflow circulation.

[0043] When the air permeability needs to be adjusted, rotating the rotating column 503 causes the fan-shaped adjustment plate 504 to deflect. The proportion of the area of ​​the adjustment plate covering the fan-shaped air vents 502 determines the ventilation efficiency of the heel area. The magnetic attraction force between the magnetic block 505 and the annular magnetic layer 506 provides positioning for the adjustment level, ensuring that the air permeability will not be accidentally changed due to movement or vibration during use.

[0044] When the foot is lifted, the tapered ventilation holes 402 of the elastic support frame 4 form a negative pressure zone, which accelerates the expulsion of hot and humid air inside the shoe through the waterproof and breathable membrane 403; when the foot is pressed down, the elastic deformation of the arc frame 401 expands the cross-sectional area of ​​the tapered holes and improves the air intake efficiency.

[0045] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
