Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clothing, in particular to a heat conduction component in a shoe. Background Art
[0002] Currently, most shoes on the market are stuffy, that is, the air permeability inside the shoes is poor and the temperature is high. The ventilation function alone can only play a ventilation effect. The temperature of the soles of the feet inside the shoes can only be equal to the temperature outside the shoes at most. When the temperature outside the shoes is not in the comfort zone of human feet, the shoes are not comfortable to wear.
[0003] By placing a phase change material with a phase change temperature lower than the temperature of the sole of the foot, when the temperature outside the shoe is lower than the phase change temperature of the phase change material, the phase change material absorbs heat relative to the sole of the foot and releases heat relative to the heat sink outside the shoe. When the phase change temperature of the phase change material is set in the comfortable temperature zone of the human foot, the comfort of wearing the shoe can be improved.
[0004] However, when the temperature outside the shoe and the temperature of the sole of the foot are both greater than the phase change temperature of the phase change material, the time it takes for the phase change material to complete the phase change will be shortened, thereby reducing the duration of the temperature regulation ability of the phase change material.

[0005] In response to the defects in the prior art, the utility model provides an in-shoe heat conduction component. This structure can disconnect the heat conduction with the outside of the shoe when the temperature outside the shoe is higher than the phase change temperature of the phase change material set inside the shoe, thereby solving the problem of the phase change time of the phase change material becoming shorter when the temperature outside the shoe is higher than the phase change temperature of the phase change material set inside the shoe.
[0006] A heat conduction component in a shoe comprises a box, a first temperature conducting member, a second temperature conducting member, a third temperature conducting member and a support rod, wherein the inner cavity of the box is divided into a solid-liquid phase change material cavity and a high-temperature phase change material cavity, the solid-liquid phase change material cavity is filled with a solid-liquid phase change material, the high-temperature phase change material cavity is filled with a high-temperature phase change material, the phase change temperature of the high-temperature phase change material is not lower than the phase change temperature of the solid-liquid phase change material, the inner end of the first temperature conducting member enters the solid-liquid phase change material cavity, the outer end of the first temperature conducting member is located outside the box, the first temperature conducting member is connected to the temperature conducting member outside the shoe, and the inner end of the second temperature conducting member enters the high-temperature phase The outer end of the third temperature conductive component is located outside the box body, and the outer end of the third temperature conductive component is connected to the temperature conductive component inside the shoe. The support rod movably penetrates the top wall of the solid-liquid phase change material cavity. An elastic soft rubber pad is arranged in the solid-liquid phase change material cavity. The elastic soft rubber pad can rise or fall with the volume change of the solid-liquid phase change material. The bottom end of the support rod is connected to the elastic soft rubber pad, and the top end of the support rod is connected to the heat-conducting pressing plate. The heat-conducting pressing plate is placed above the outer end of the first temperature conductive component and the outer end of the second temperature conductive component.
[0007] Preferably, the phase change temperature of the high-temperature phase change material is higher than that of the solid-liquid phase change material.
[0008] Preferably, a fixed box is further included, wherein the fixed box is arranged on the outer top wall of the box body, and an elastic sheet is arranged on the inner top wall of the fixed box, and the elastic sheet is in contact with the top wall of the heat-conducting pressing sheet.
[0009] Preferably, the area of the second temperature conducting component located in the high-temperature phase change material cavity is larger than the area of the third temperature conducting component located in the high-temperature phase change material cavity.

At this time, the high-temperature phase change material undergoes phase change and absorbs heat, cooling the sole of the foot. At the same time, because the temperature outside the shoe is higher than the phase change temperature of the solid-liquid phase change material and the solid-liquid phase change material has not completed the phase change, the temperature outside the shoe is transmitted to the solid-liquid phase change material.

[0024] Example 1
[0025] like Figure 1-Figure 5 As shown, in this embodiment, a shoe heat conduction component is provided, including a box body 1, a first temperature conducting member 4, a second temperature conducting member 5, a third temperature conducting member 6 and a support rod 7. The inner cavity of the box body 1 is divided into a solid-liquid phase change material cavity 2 and a high-temperature phase change material cavity 3. The solid-liquid phase change material cavity 2 is filled with solid-liquid phase change material, and the high-temperature phase change material cavity 3 is filled with high-temperature phase change material. The phase change temperature of the high-temperature phase change material is not lower than the phase change temperature of the solid-liquid phase change material. The inner end of the first temperature conducting member 4 enters the solid-liquid phase change material cavity 2, and the outer end of the first temperature conducting member 4 is located outside the box body 1. The first temperature conducting member 4 is connected to the temperature conducting member outside the shoe. The inner end of the second temperature conducting member 5 enters the high The outer end of the third temperature conducting member 6 is connected to the temperature conducting member in the shoe, and the support rod 7 movably penetrates the top wall of the solid-liquid phase change material cavity 2. An elastic soft rubber pad 11 is arranged in the solid-liquid phase change material cavity 2. The elastic soft rubber pad 11 can rise or fall with the volume change of the solid-liquid phase change material. The bottom end of the support rod 7 is connected to the elastic soft rubber pad 11, and the top end of the support rod 7 is connected to the heat conductive pressing plate 8. The heat conductive pressing plate 8 is placed above the outer end of the first temperature conducting member 4 and the outer end of the second temperature conducting member 5.
[0026] In this embodiment, the high temperature phase change material may be a solid-solid phase change material or a solid-liquid phase change material.
[0027] When used specifically, the inner shoe heat conducting member is located at the sole, and the outer shoe heat conducting member is located outside the shoe. In this embodiment, through the cooperation of various components, the specific use is as follows:
[0028] When the temperature outside the shoe and the temperature of the sole are both higher than the phase change temperature of the high-temperature phase change material, and the high-temperature phase change material has not completed the phase change, the temperature of the sole is transmitted to the third temperature conductive member 6 through the temperature conductive member inside the shoe, and then transmitted to the high-temperature phase change material cavity 3. At this time, the high-temperature phase change material undergoes phase change and absorbs heat, cooling the sole. At the same time, the temperature outside the shoe is higher than the phase change temperature of the solid-liquid phase change material and the solid-liquid phase change material has not completed the phase change, so the temperature outside the shoe is transmitted to the solid-liquid phase change material. At this time, the solid-liquid phase change material absorbs heat and liquefies due to the temperature increase, and the volume increases. The elastic soft rubber pad 11 is deformed, and the support rod 7 connected to the elastic soft rubber pad 11 is displaced. The support rod 7 lifts up the heat-conducting pressing plate 8, and the heat-conducting pressing plate 8 is disconnected from the outer end of the first temperature conductive member 4 and the outer end of the second temperature conductive member 5. At this time, the connection between the high-temperature phase change material and the outside of the shoe is disconnected. At this time, the high-temperature phase change material will not absorb heat from the outside of the shoe, thereby extending the phase change time of the high-temperature phase change material.
[0029] When the temperature outside the shoe is lower than the phase change temperature of the solid-liquid phase change material, the temperature of the sole of the foot is higher than the phase change temperature of the high-temperature phase change material, and the phase change material has not completed the phase change, the temperature of the sole of the foot is conducted to the third temperature conducting component 6 through the temperature conducting component inside the shoe, and then conducted to the high-temperature phase change material through the third temperature conducting component 6. At this time, the high-temperature phase change material undergoes phase change and absorbs heat to cool the sole of the foot. The temperature outside the shoe is lower than that of the solid-liquid phase change material and the solid-liquid phase change material has not completed the phase change. At this time, the temperature difference between the solid-liquid phase change material and the outside of the shoe generates heat transfer. At this time, the temperature of the solid-liquid phase change material decreases, releases heat and solidifies, and the volume decreases. The elastic soft rubber pad 11 deforms, and the elastic soft rubber pad 11 drives the support rod 7 to descend. The heat-conducting pressure plate 8 moves downward and contacts the outer end of the first temperature conductive component 4 and the outer end of the second temperature conductive component 5, connecting the first temperature conductive component 4 and the second temperature conductive component 5, so that the high-temperature phase change material absorbs heat from the sole of the foot inside the shoe while releasing heat to the outside through the second temperature conductive component 5, the first temperature conductive component 4 and the temperature conductive component outside the shoe. At this time, the high-temperature phase change material always keeps absorbing heat and releasing heat, thereby maintaining a phase-changeable state.
[0030] When the temperature outside the shoe and the temperature of the sole are both lower than the phase change temperature of the solid-liquid phase change material, the sole of the foot is lower than the temperature of the solid-liquid phase change material, and the temperature outside the shoe is also lower than the temperature of the solid-liquid phase change material. At this time, the whole system is in a fully connected state, the solid-liquid phase change material has completed the exothermic reaction, and the whole system fails. The thermal conductivity of the high-temperature phase change material is much lower than that of the thermal conductive component. The heat inside the shoe will slowly be conducted to the outside of the shoe, but most of the heat inside the shoe will accumulate inside the shoe. At this time, the heat of the foot inside the shoe is slowly lost. Until the angle temperature rises to above the phase change temperature of the high-temperature phase change material after exercise, the system resumes operation. If the temperature difference between the inside and outside of the shoe is large, the connection can be manually disconnected, that is, the connection between the third thermal conductive component 6 and the thermal conductive component inside the shoe is disconnected to ensure the temperature of the foot.
[0031] For example, when the phase change temperatures of the solid-liquid phase change material and the high-temperature phase change material are both 30 degrees.
[0032] When the temperature outside the shoe is 32 degrees and the temperature of the sole is 36 degrees, the solid-liquid phase change material undergoes an endothermic reaction, the solid-liquid phase change material liquefies, the volume increases, the support rod 7 moves upward, the high-temperature phase change material is disconnected from the outside of the shoe, and the high-temperature phase change material is connected to the inside of the shoe alone, thereby extending the reaction time of the high-temperature phase change material.
[0033] When the temperature outside the shoe is 26 degrees and the temperature of the foot is 33 degrees, the solid-liquid phase change material reacts exothermically to the outside, solidifies, and the volume decreases. The support rod 7 moves downward, so that the high-temperature phase change material is connected to the outside of the shoe. The high-temperature phase change material reacts endothermically with the sole of the foot and reacts exothermically with the outside of the shoe. At this time, the high-temperature phase change material always absorbs and releases heat, thereby maintaining a phase-changeable state.
[0034] When the temperature outside the shoe is 18 degrees and the temperature of the sole is 25 degrees, the solid-liquid phase change material and the high-temperature phase change material do not react. Since the thermal conductivity of the high-temperature phase change material is lower than that of the thermal conductive component, most of the heat in the shoe is concentrated inside the shoe, and a small part of the heat is conducted to the outside of the shoe through the high-temperature phase change material. The whole system resumes operation until the temperature inside the shoe is higher than the phase change temperature of the high-temperature phase change material.
