Description

Technical Field

[0001] The utility model belongs to the technical field of shoe production, and particularly relates to a unidirectional ventilation and air exchange sole and a shoe prepared therefrom. Background Art

[0002] In the existing shoes, the air circulation inside the shoes is not smooth. After the feet sweat, the sweat staying inside the shoes will breed bacteria, resulting in foot odor and shoe odor, and it is also easy to cause foot diseases.

[0003] The prior art (CN201085125Y) provides an electric ventilation sole. The ventilation sole uses a micro motor and a ventilation pump to pump the humid air inside the shoes from the air holes, air cavities, and ventilation channels to the air outlet channel and discharge it outside the sole body. However, no waterproof measures are taken at the air outlet channel. If the ground is slippery or it is raining, during walking, water will inevitably enter the inside of the shoe heel through the air outlet channel, damaging the motor and the ventilation pump. In addition, the air cavity of this sole is located between the inner sole and the outer sole and is mainly formed by the structure of the inner sole. The pressure generated by the sole of the foot will directly act on the inner sole. Although cylinders and support columns are provided on the surface and inner wall of the inner sole, the pressure generated by the sole of the foot, especially the pressure generated by the front sole and the rear heel, is relatively large. The cylinders and support columns bear a relatively large pressure, and the inner sole at this part is prone to soft collapse and deformation, damaging the air cavity structure.

[0004] The prior art (CN 202738932 U) provides an electric ventilation shoe. The ventilation shoe uses a suction fan to pump the outside air from the air inlet and air outlet of the suction fan to the air supply pipe of the sole, and supplies fresh air to the inside of the shoe through the air supply holes. However, the air inlet of the suction fan is directly connected to the outside without waterproof treatment, which is easy to damage the air supply equipment inside the shoe and reduce the service life of the ventilation shoe. In addition, setting the air supply pipe inside the sole makes the manufacturing process complex. There is only one main path for the air supply pipe of this sole. During walking, the sole will inevitably bend. If this main path is blocked, fresh air cannot be smoothly supplied to the inside of the shoe. Summary of the Invention

Detailed implementation manners

[0028] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described implementation manners are some but not all of the implementation manners of the present utility model. Based on the implementation manners in the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model. Therefore, the following detailed description of the implementation manners of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected implementation manners of the present utility model.

[0029] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "left", "right", "upper", "lower", "top", "bottom", "front", "rear", "inner", "outer", "back", "middle", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0030] The present utility model provides a unidirectional ventilation and air change outsole, as Figures 1 - 5 shown, the outsole 1 includes an outer layer sole 11, and an inner layer sole 12 is fixed on the outer layer sole. The outer layer sole 11 has anti-slip and wear-resistant properties, and the inner layer sole 12 has shock-absorbing functions and lightweight properties.

[0031] The inner sole 12 includes a forefoot portion, a middle portion and a heel portion. Ventilation grooves 14 are provided on the upper surfaces of the forefoot portion and the middle portion of the inner sole. An installation space 16 communicating with the ventilation grooves 14 is provided inside the heel portion of the inner sole. A gas driving device and a circuit module for powering it are provided in the installation space 16. An isolation cloth 13 is laid on the inner sole. The isolation cloth is fixed on the inner sole by means of adhesion, closing the transverse ventilation grooves 14a and the longitudinal ventilation grooves 14b distributed on the inner sole to form a closed space to prevent air leakage. At the same time, ventilation holes 15 are provided on the isolation cloth. The ventilation holes 15 correspond to the ventilation grooves. The air in the ventilation grooves can flow into the space below the isolation cloth 13 through the ventilation holes on the isolation cloth 13. The installation space 16 communicates with the outside through an air duct. A waterproof air outlet 3 with adjustable air volume is provided on the air duct. The air in the external environment can enter the installation space 16 through the waterproof air outlet, and under the operation of the gas driving device and the circuit module, the gas is transported to the ventilation grooves and enters the upper part of the outsole 1 through the ventilation holes 15.

[0032] The circuit module includes a battery pack 5, an electronic speed control component 6, a charging port 4, and a PCB board 9. The PCB board 9 is electrically connected to the battery pack 5, the electronic speed control component 6, the charging port 4, and the gas driving device.

[0033] In this solution, the gas driving device is a micro fan. Compared with other types of fans, an obvious air flow can be felt when an outrunner brushless fan is installed at the heel of the shoe. The micro fan is preferably a micro high-speed brushless fan 2. The fan is powered by a rechargeable battery pack. The air volume and air pressure of the fan can be adjusted. The fan starts flexibly under the control of the electronic speed control component. The heat generated by the high-speed operation of the fan is carried away by the air flow, ensuring the reliability of the long-term continuous operation of the fan. The fan has the following characteristics: high rotational speed, low power consumption, large air flow pressure, and small size.

[0034] Such as Figure 10As shown in the figure, the number of blades of the fan blade 23 is 9 to 11, evenly distributed along the circumference of the blade. The helix direction on the cylindrical surface where the geometric mean diameter of the blade is located is right-handed or left-handed, and the helix angle is 30°. During the research, development and manufacturing of the fan blade, high-speed dynamic balance testing is carried out. It is required to have high rotation accuracy to improve the fan efficiency and reduce the airflow noise. The noise can be reduced to no more than 50 dB. At this time, the fan noise basically causes no discomfort to the wearer. The material of the fan blade is aluminum alloy, and it is processed by a CNC machine tool, which can ensure that the fan blade has high geometric dimension accuracy and position accuracy. There are 5 to 7 flow guide grooves designed in the support component 24. The flow guide grooves are separated by spiral flow guide plates, and the flow guide plates are evenly distributed in the circumference. The material is aluminum alloy, and the blank is manufactured by die casting with a metal mold, and the internal round hole is turned to ensure the dimension accuracy and position accuracy. The motor uses a low-voltage DC high-speed brushless motor, and the maximum speed can reach 130000 RPM. The motor is also a part of the ventilation shoe and boot industrial chain, and will not be elaborated here. The motor should meet the requirements of high speed and low noise, and ensure the accuracy requirements after the motor 25, the support component 24 and the fan blade 23 are assembled, so as to ensure that the fan has good aerodynamic characteristics.

[0035] As Figure 2 shown in the figure, a charging port 4 is provided on the battery pack 5. The charging port 4 is arranged on the side of the heel of the outsole, and a flip cover is arranged on the charging port to block the charging port when not charging to prevent water or dust from entering and damaging the charging port.

[0036] As Figure 6 shown in the figure, the waterproof air vent 3 is a rotatable and adjustable air vent, which is stepless adjustment. It includes a handle 31. The handle 31 is fixedly connected with a connecting rod 34. The connecting rod passes through a fixed air duct 32, and the two are threadedly connected. By rotating the handle, the distance between the handle and the fixed air duct is controlled, that is, the opening and closing degree of the waterproof air vent is controlled, and then the air volume of the air inlet and outlet is adjusted; when it rains or the ground is wet, the air vent can be closed by rotation to prevent water from entering the sole through the air vent and damaging the ventilation equipment.

[0037] A synchronous adjustment mechanism is arranged in the installation space to realize the synchronous adjustment of the ventilation volume and the fan speed. There are two implementation methods for the synchronous adjustment mechanism;

[0038] The first method is:

[0039] The electric adjustment component adopted is a potentiometer. By rotating the hidden knob 7 on the potentiometer, the resistance can be changed, and then the fan speed can be controlled. A brushless electronic speed controller can also be used to adjust the fan speed.

[0040] As Figures 6 - 8As shown in the figure, the synchronous adjustment mechanism is arranged between the concealed knob 7 and the connecting rod. One end of the concealed knob 7 close to the waterproof air outlet 3 is fixedly connected with a coupling block 33, and the coupling block 33 can drive the knob to rotate; the coupling block 33 is provided with a central hole 331 that matches the diameter of the connecting rod, and an axially extending sliding groove 332 is formed on the side wall of the central hole; on the side of one end of the connecting rod 34 away from the handle 31, a positioning protrusion 341 that matches the shape of the sliding groove is provided; the connecting rod 34 is slidably connected with the coupling block 33 through the positioning protrusion 341 and the sliding groove 332. Rotating the handle, the handle drives the connecting rod to rotate, and the connecting rod drives the coupling block to rotate. During the process of rotating the handle, the handle and the connecting rod not only rotate, but also have an axial displacement; in order to eliminate the axial displacement, in the present invention, the coupling block is fixed on the concealed knob 7, and the connecting rod 34 and the coupling block 33 are slidably connected through the positioning protrusion 341 and the sliding groove 332. When the connecting rod drives the coupling block to rotate, the positioning protrusion 341 slides in the sliding groove 332 to perform an axial movement, eliminating the axial displacement of the coupling block and only retaining the circumferential rotation of the coupling block.

[0041] The working process is as follows: When the handle 31 is rotated counterclockwise, the opening degree of the waterproof air outlet 3 gradually increases. The connecting rod and the fixed air duct are connected by a thread. The handle 31 drives the connecting rod 34 to rotate and perform a spiral movement. The handle 31 and the connecting rod 34 not only rotate, but also have an axial displacement relative to the fixed air duct and move in the direction of the handle. The positioning protrusion 341 on the connecting rod 34 will slide in the sliding groove 332 of the coupling block 33; when the handle 31 rotates one week, the opening degree of the waterproof air outlet 3 is the largest, and the air volume of the air inlet and outlet is the largest. The axial displacement of the handle and the connecting rod relative to the fixed air duct is the largest, and the positioning protrusion slides to the right side of the sliding groove; then when the handle is rotated clockwise, the opening degree of the waterproof air outlet gradually decreases, the axial displacement of the handle and the connecting rod relative to the fixed air duct decreases, and the positioning protrusion slides to the left in the sliding groove until the leftmost side, at which time the opening degree of the waterproof air outlet is the smallest; in the above process, through the positioning protrusion and the sliding groove, the coupling block and the handle rotate synchronously without axial displacement. The coupling block is fixedly connected with the concealed knob 7, so that the concealed knob 7 and the handle 31 rotate synchronously. By rotating the handle, the resistance of the potentiometer is changed, thereby controlling the speed of the brushless fan and realizing the synchronous adjustment of the ventilation volume and the fan speed.

[0042] At the same time, there are limit walls 333 on both the left and right sides of the sliding groove 332 to prevent the positioning protrusion 341 from falling off from the sliding groove 332. The sliding groove and the positioning protrusion are correspondingly arranged. The sliding groove and the positioning protrusion can be provided with one pair, two pairs or multiple pairs. When both the sliding groove and the positioning protrusion are provided with two, the sliding grooves are symmetrically arranged on the side wall of the central hole, and the positioning protrusions are symmetrically arranged on the side of the end of the connecting rod.

[0043] The second method is:

[0044] Such as Figure 9As shown in the figure, one end of the connecting rod 34 away from the handle is fixedly connected with a connecting block 33. The connecting block 33 is cylindrical, and the outer side surface of the connecting block 33 is in direct contact with the resistance wire of the rheostat. The linkage block is electrically connected to the blower. The connecting block is equivalent to the pointer on the rheostat. The connecting block and the rheostat form an electric adjustment component. By moving the position of the connecting block, the resistance is changed, so as to achieve the purpose of changing the speed of the blower. Rotating the handle 31 drives the connecting rod 34 to rotate and generate an axial displacement. The connecting rod 34 drives the connecting block 33 to rotate and generate an axial displacement. Since the connecting block 33 is cylindrical, during the rotation process, it is ensured that the connecting block and the resistance wire of the rheostat always remain in contact and have a relative displacement, changing the resistance. By rotating the handle to change the resistance, the speed of the brushless blower is controlled, and the synchronous adjustment of the ventilation volume and the blower speed is realized.

[0045] As Figure 2 shown, the ventilation slots 14 are distributed in a "leaf shape", including transverse ventilation slots 14a and longitudinal ventilation slots 14b. Among them, multiple longitudinal ventilation slots 14b are provided, preferably three, extending longitudinally along the sole. One ends of the three longitudinal ventilation slots 14b are connected together at the toe of the shoe, and the other ends are arranged at the air outlet of the blower; by providing multiple longitudinal ventilation slots 14b, if one ventilation slot is blocked, other ventilation slots can be used to convey air; the transverse ventilation slots 14a are distributed longitudinally along the sole and are connected to the longitudinal ventilation slots 14b to convey the gas to various positions.

[0046] A module 8 is provided at the bottom of the installation space 16. The micro high-speed brushless blower, the circuit module and the waterproof air outlet 3 are installed in the installation module 8 made of plastic material to fix and protect each component; at the same time, the module 8 can support the sole to avoid collapse.

[0047] As Figures 4 - 5 shown, a shoe or boot including a unidirectional flow ventilation and air change sole. The shoe or boot includes a sole 1 and an upper 100. A midsole 19 and an insole 18 are successively provided on the sole 1. Both the midsole 19 and the insole 18 are provided with ventilation holes. A conventional upper is connected above the sole. For example, in the case of the sock lining process, a midsole cloth is connected above the sole, and the openings on the midsole cloth correspond to the openings on the isolation cloth 13, ensuring that the air flow generated by the blower passes through the ventilation slots 14 and then through the ventilation holes 15 on the isolation cloth 13, through the corresponding holes on the midsole cloth, and then through the corresponding holes on the perforated insole 12 into the shoe or boot; in the case of the lasting process, the upper 100 is composed of a vamp, a shoe lining, and a midsole 19, and the air flow enters the shoe or boot through the midsole 19 and the insole 18.

[0048] According to the different installation positions of the air outlet and air inlet of the blower, the unidirectional ventilation and air change shoes or boots are divided into unidirectional flow positive pressure ventilation and air change shoes or boots and unidirectional flow negative pressure ventilation and air change shoes or boots. The positions of the air outlet and air inlet of the blower can be adjusted in two ways: by adjusting the installation direction of the blower or by adjusting the left or right rotation of the blower fan blades.

[0049] As Figure 5 shown, when the air outlet of the blower faces the ventilation groove and is away from the waterproof air outlet, the sole is the sole for unidirectional flow positive pressure ventilation and air change of the blower. The working process is as follows: First, rotate the handle to open the waterproof air outlet and drive the hidden knob 7 to rotate. The power is turned on, and the electronic control component is powered on. Under the control of the electronic control component, the blower transitions from a stationary state to the lowest speed (soft start) and then operates normally. The high-speed brushless blower 2 operates at the lowest speed. The blower impeller sucks the air outside the sole into the blower, and the high-pressure air is pushed into the air outlet 22 of the blower through the blower barrel. Then, through the longitudinal ventilation groove 14b, the transverse ventilation groove 14a, and the ventilation hole 15, the positive pressure air is pushed into the shoe. The air pressure inside the shoe is greater than the atmospheric pressure, and the high-pressure air inside the shoe flows out through the gaps in the shoe upper material or the gaps between the shoe upper and the ankle, forming a positive pressure air flow channel 17b.

[0050] As Figure 4 shown, when the air outlet of the blower faces away from the ventilation groove and towards the waterproof air outlet, the sole is the sole for unidirectional flow negative pressure ventilation and air change of the blower. The working process is as follows: First, rotate the handle to open the waterproof air outlet and drive the hidden knob 7 to rotate. The power is turned on, and the electronic control component is powered on. Under the control of the electronic control component, the blower transitions from a stationary state to the lowest speed (soft start) and then operates normally. The high-speed brushless blower 2 operates at the lowest speed. The blower impeller extracts the air inside the sole through the ventilation hole 15, the transverse ventilation groove 14a, the longitudinal ventilation groove 14b, then through the air inlet 21 of the blower, and the negative pressure air is extracted and compressed and pushed out of the sole through the blower barrel. The air pressure inside the shoe is less than the atmospheric pressure, and the external air enters the shoe through the gaps in the shoe upper material or the gaps between the shoe upper and the ankle and is then extracted out of the sole by the blower, forming a negative pressure air flow channel 17a.

[0051] Taking the outer diameter of the fan as 18 mm and the height of the shoe heel not less than 3 cm as an example, the fan is configured with a BL180M, a brushless motor with a KV value of 11750, and powered by a 7.4V voltage. The lowest gear fan speed is set at about 30000 RPM and the power is 3W. Two 3.7V, 3400mAh lithium batteries are connected in series with a battery life of 8 hours. When the ventilation effect is not good, rotate the handle again to enlarge the air outlet and drive the hidden knob to rotate. The fan flexibly adjusts the speed to the intermediate speed. At this time, the fan speed is about 60000 RPM and the power is 6W, and the battery life is 4 hours. When the ventilation and air exchange effect is still poor, continue to rotate the handle to adjust the air outlet to the maximum, drive the hidden knob to rotate, and the fan flexibly accelerates to the highest speed. At this time, the fan speed is about 90000 RPM and the power is 9W, and the battery life is 2 hours. When not in use, rotate the handle in the reverse direction until the air outlet is closed, drive the hidden knob to rotate until the power is turned off and the fan stops running. When the ventilation time of any gear setting is up, the power will automatically turn off. In the actual test in the hot summer, when the fan speed is set at the lowest speed gear, the human comfort feeling is already very good. The maximum fan speed is 100000 RPM and the maximum power is about 13W. The maximum fan speed is limited to 90000 RPM and the power is about 9W.

[0052] For soles with a thickness less than 3 cm at the heel part of the sole or a smaller sole heel size, select a fan outer diameter size of 16 mm or 14 mm. The size and capacitance of the supporting battery will decrease accordingly, and the battery life ability will basically remain unchanged. When the fan is too small, the manufacturing difficulty increases and the ventilation effect generated by the fan decreases, but the body feeling is still obvious. Therefore, by installing a micro high-speed fan in the sole part to perform forced ventilation and air exchange inside the shoe, the effect cannot be achieved by any other ventilation and air exchange shoes, and it is the most effective way to substantially solve or improve the ventilation and air exchange of the sole or shoe.

[0053] The utility model provides a sole and a shoe that can significantly improve the ventilation and air exchange performance of the sole without changing the appearance of the sole. A micro high-speed brushless fan, a rechargeable battery pack, a fan electronic speed controller component and a waterproof air outlet with adjustable air volume are installed in the space at the heel part of the sole, which can significantly improve the air permeability of the shoe sole, reduce the humidity and temperature inside the shoe sole, and significantly improve the wearing comfort; improve the microenvironment inside the shoe, prevent bacteria from growing inside the shoe, and prevent or reduce foot odor and other odors; there is a stable negative pressure or positive pressure air flow passing through the shoe sole, which can accelerate the evaporation of moisture, avoid the phenomenon of wet, hot and stuffy feet; the wearer can obviously feel the air flow passing through the toes, soles and insteps of the feet, and the degree of feeling is adjustable; the ventilation and air permeability effect provided by the shoes of the utility model is incomparable to that of any other ventilation and air exchange shoe soles or shoes.

[0054] The utility model installs a waterproof air outlet in the ventilation channel for exchanging air with the outside world, which can effectively prevent the entry of moisture or dust and damage the ventilation equipment.

[0055] In the utility model, the connecting rod of the waterproof air outlet is connected with the hidden knob through a linkage block, and the axial displacement is eliminated through the positioning protrusion and the sliding groove, so that the handle of the waterproof air outlet rotates synchronously with the hidden knob. By rotating the handle, the resistance of the potentiometer is changed, thereby controlling the rotation speed of the brushless fan and realizing the synchronous adjustment of the ventilation volume and the fan rotation speed.

[0056] The ventilation groove provided by the utility model is "leaf-shaped", including three longitudinal ventilation grooves and transverse ventilation grooves connecting the longitudinal ventilation grooves, which can enable the gas to flow to each part. In addition, according to the wearing habit, creases will inevitably appear on the sole and the upper surface of the shoe during walking. If one of the ventilation grooves is blocked, the gas can also be conveyed to each part by the cooperation of other longitudinal ventilation grooves and transverse ventilation grooves; the ventilation groove is arranged on the upper surface of the inner layer sole, and the isolation cloth and the midsole cloth are directly covered on it, and the manufacturing process is simple.

[0057] The above are only the preferred embodiments of the utility model. It should be pointed out that for those skilled in the art, without departing from the overall concept of the utility model, several changes and improvements can still be made, and these should also be regarded as the protection scope of the utility model.
