Description

Technical Field

[0001] This utility model relates to the field of composite shoe technology, specifically an outdoor mountaineering composite shoe. Background Technology

[0002] Outdoor mountaineering composite shoes are a type of multi-functional footwear designed specifically for complex mountain environments. They combine the stability of traditional mountaineering shoes with the flexibility of modern sports shoes. With a composite structure design, they integrate multiple functions such as waterproofing, breathability, slip resistance, shock absorption, and support, making them suitable for various outdoor activities such as hiking, rock climbing, and trail running.

[0003] While most outdoor hiking boots on the market are relatively mature in terms of waterproofing and protection, they still have inherent shortcomings in managing their internal microclimate. The interior of the shoe often becomes damp and stuffy due to the continuous heat and sweat generated by the feet during hiking. This accumulated moisture and heat is difficult to dissipate passively through static materials, resulting in a persistently uncomfortable "high temperature and high humidity" state inside the shoe. Simultaneously, odor molecules generated by this condition remain trapped inside the shoe cavity for extended periods. The lack of an effective active purification mechanism means that the freshness of the shoes quickly disappears after each outdoor activity, affecting not only immediate comfort but also causing hygiene and maintenance problems for subsequent use. Therefore, we propose a composite outdoor hiking shoe. Utility Model Content

[0004] The purpose of this invention is to provide an outdoor mountaineering composite shoe to address the shortcomings of most outdoor mountaineering shoes currently on the market, which, while relatively mature in terms of waterproofing and protection, still have inherent shortcomings in the management of their internal microclimate. The internal environment of the shoe often becomes damp and stuffy due to continuous heat and sweating from the feet during hiking. This accumulated moisture and heat is difficult to dissipate passively through static materials, resulting in a persistently uncomfortable "high temperature and high humidity" state inside the shoe. Furthermore, the resulting odor molecules remain trapped inside the shoe cavity for extended periods, lacking an effective active purification mechanism. This causes the freshness of the shoes to quickly disappear after each outdoor activity, affecting not only immediate comfort but also causing hygiene and maintenance problems for subsequent use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an outdoor mountaineering composite shoe, including a sole, with a shoe body sewn to the upper end of the sole by hemp thread; an air intake chamber is provided near the center of the sole, a rubber support column is fixedly connected inside the air intake chamber, and a ventilation hole is provided at the top of the air intake chamber; a cushioning chamber is provided near one side of the sole, an airbag is fixedly connected to the center of the cushioning chamber, and cushioning springs are fixedly connected to the front and rear ends of both sides of the cushioning chamber; the two ends of the airbag are respectively fixedly connected to... The system includes a No. 1 connecting pipe and a No. 2 connecting pipe. An air passage is provided between the air intake chamber and the buffer chamber. A filter chamber is provided on one side of the outer wall of the sole. A No. 1 intercepting filter is fixedly installed on one side of the filter chamber. Activated carbon particles are provided inside the filter chamber. A screw-in cap is provided on one side of the filter chamber. A rotating disk is fixedly installed on one side of the outer wall of the screw-in cap. The screw-in cap has a hollow structure inside. One side of the screw-in cap extends into the interior of the filter chamber. A No. 2 intercepting filter and a dustproof net are fixedly installed on both sides of the screw-in cap, respectively.

[0006] Compared with the prior art, the beneficial effects of this utility model are: This outdoor mountaineering composite shoe features an air intake chamber, ventilation holes, rubber support pillars, cushioning chamber, air bladder, first connecting tube, air duct, second connecting tube, filter chamber, activated carbon particles, first interception filter, screw-in cap, second interception filter, and dustproof mesh. It utilizes the periodic compression and rebound of the foot against the air bladder during walking to create a pumping effect, allowing it to operate continuously without external power. During compression, it expels hot and humid air from inside the shoe; during rebound, it actively draws in fresh air through the entire air intake channel. This dynamic cycle completely changes the passive mode of traditional mountaineering shoes that rely solely on static material breathability, achieving a leap from "static" to "dynamic," significantly improving the efficiency of moisture and heat removal from inside the shoe. External air, during its intake, must pass through the filter chamber filled with activated carbon particles. Activated carbon efficiently adsorbs odor molecules and trace amounts of harmful gases in the air, ensuring that the air entering the shoes is not only fresh and dry but also clean. This chemical adsorption process fundamentally solves the problem of stubborn shoe odor caused by bacteria growing in sweat, providing users with a lasting fresh experience. Through the dual physical protection of the No. 1 interception filter and the dustproof net, dust and debris are effectively prevented from clogging the filter chamber and air passage, ensuring smooth airflow. At the same time, the screw-in cap design with a threaded connection makes the filter chamber an easily openable modular unit, greatly facilitating users to regularly clean or replace saturated activated carbon particles, ensuring long-term stability of purification performance.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] Please see Figure 1-4 This utility model provides a technical solution: an outdoor mountaineering composite shoe, including a sole 1, with a shoe body 2 sewn to the upper end of the sole 1 by hemp thread. An air intake chamber 3 is located near the center of the sole 1, and a rubber support column 5 is fixedly connected inside the air intake chamber 3. A ventilation hole 4 is located at the top of the air intake chamber 3. A cushioning chamber 6 is located near one side of the sole 1, and an airbag 7 is fixedly connected to the center of the cushioning chamber 6. Cushioning springs 8 are fixedly connected to the front and rear ends of both sides of the cushioning chamber 6. A first connecting pipe 9 and a second connecting pipe are fixedly connected to both ends of the airbag 7, respectively. 11. An air passage 10 is provided between the air intake chamber 3 and the buffer chamber 6. A filter chamber 12 is provided on one side of the outer wall of the shoe sole 1. A first intercepting filter 14 is fixedly installed on one side of the filter chamber 12. Activated carbon particles 13 are provided inside the filter chamber 12. A screw-in cap 15 is provided on one side of the filter chamber 12. A rotating disk 20 is fixedly installed on one side of the outer wall of the screw-in cap 15. The inside of the screw-in cap 15 is hollow. One side of the screw-in cap 15 extends into the inside of the filter chamber 12. A second intercepting filter 16 and a dustproof net 17 are fixedly installed on both sides of the screw-in cap 15, respectively.

[0011] The number of rubber support columns 5 and the number of ventilation holes 4 are set in a certain number. The rubber support columns 5 can effectively disperse the pressure on the sole of the foot and prevent the air inlet cavity 3 from collapsing when under force, ensuring that the air circulation channel remains unobstructed at all times. The number of ventilation holes 4 increases the contact area with the space inside the shoe, making air exchange more uniform and efficient.

[0012] One side of the No. 1 connecting pipe 9 is fixedly connected to one side of the inner wall of the buffer chamber 6, and one end of the No. 1 connecting pipe 9 is connected to one side of the air passage 10. This structure establishes a fixed airflow path between the airbag 7 and the air intake chamber 3. When the airbag 7 is compressed, the gas can be forced through the No. 1 connecting pipe 9 and the air passage 10 and discharged from the air intake chamber 3, forming a stable exhaust channel.

[0013] One end of the second connecting pipe 11 is fixedly connected to the other side of the inner wall of the buffer chamber 6, and one side of the second connecting pipe 11 is connected to one side of the filter chamber 12. This structure establishes a fixed airflow path between the airbag 7 and the filter chamber 12. When the airbag 7 rebounds and generates negative pressure, external air is forced to be drawn in through the filter chamber 12 and the second connecting pipe 11, ensuring that all incoming air is filtered and purified.

[0014] The outer wall of the rotating disc 20 is provided with anti-slip vertical grooves, which significantly increase the friction between the user's fingers and the rotating disc 20, making the operation of screwing the cover 15 easier and more convenient, especially when the hands are wet or covered with mud outdoors.

[0015] A thread 19 is provided on one side of the outer wall of the screw-in cap 15, and a thread groove 18 is provided on one side of the inner wall of the filter chamber 12. The thread 19 and the thread groove 18 are threadedly connected, which realizes the complete sealing and quick opening and closing of the filter chamber 12, making it convenient for users to replace the activated carbon particles 13 regularly.

[0016] Working principle: When the user's foot steps on the ground, the pressure of the foot acts on the cushioning chamber 6. This pressure is cushioned by the cushioning spring 8 and directly compresses the airbag 7 located in the center. The compressed airbag 7 forces the air inside into the air intake chamber 3 through the connecting pipe 9 and the air passage 10. Subsequently, the air is discharged upward through several ventilation holes 4 at the top of the air intake chamber 3 and directly into the shoe. This process agitates the accumulated hot and humid air inside the shoe through air flow and accelerates its discharge from the shoe surface. At the same time, the rubber support column 5 ensures that the air intake chamber 3 does not collapse under pressure, ensuring smooth airflow. When the user lifts their foot and the foot pressure is released, the compressed cushioning spring 8 and the airbag 7 return to their original shape due to their elasticity, creating a negative pressure suction force within the cushioning chamber 6. Under this negative pressure, fresh outside air first passes through the dust filter 17 on one side of the screw-in cover 15, where dust and large particles are filtered out. Then, the air passes through the second interceptor filter 16 and enters the filter chamber 12 filled with activated carbon particles 13, where odor molecules are adsorbed and purified. The purified air then passes through the first interceptor filter 14 for secondary interception. Finally, the clean air is drawn into the restored airbag 7 via the second connecting pipe 11, preparing for the next exhaust cycle.

[0017] In summary, this outdoor mountaineering composite shoe, through the design of an air intake chamber 3, ventilation hole 4, rubber support column 5, cushioning chamber 6, air bladder 7, first connecting pipe 9, air channel 10, second connecting pipe 11, filter chamber 12, activated carbon particles 13, first interception filter 14, screw cap 15, second interception filter 16, and dustproof net 17, utilizes the periodic compression and rebound of the foot against the air bladder 7 during walking to create a pumping effect. It can work continuously without external energy. During compression, it expels hot and humid air from inside the shoe; during rebound, it actively draws in fresh air from outside through the entire air intake channel. This dynamic cycle completely changes the passive mode of traditional mountaineering shoes that only rely on static material breathability, achieving a leap from "static" to "dynamic". It significantly improves the efficiency of moisture and heat removal from inside the shoe. During the process of external air being drawn into the shoe, it must flow through the filter chamber 12 filled with activated carbon particles 13. Activated carbon can efficiently adsorb odor molecules and trace amounts of harmful gases in the air, making the air entering the shoes not only fresh and dry, but also clean. This chemical adsorption process fundamentally solves the problem of stubborn shoe odor caused by bacteria growing in sweat, providing users with a lasting fresh experience. Through the dual physical protection of the No. 1 interceptor filter 14 and the dustproof net 17, dust and debris are effectively prevented from clogging the filter chamber 12 and the air passage, ensuring smooth airflow. At the same time, the screw-in cap 15 design with a threaded connection makes the filter chamber 12 an easily openable modular unit, which greatly facilitates users to regularly clean or replace the saturated activated carbon particles 13, ensuring long-term stability of purification efficiency.
