Description

Technical Field

[0001] This invention relates to a type of waterproof footwear with forced ventilation, belonging to the technical field of waterproof footwear. Background Technology

[0002] Existing waterproof footwear and trousers have significant drawbacks in terms of forced ventilation. The main issue is that moisture and heat easily accumulate inside, causing stuffiness and damp skin, severely impacting work comfort and physiological function. These shortcomings stem from the high sealing properties of waterproof materials. To achieve absolute waterproofing, dense, impermeable materials are typically used. While preventing external moisture from entering, this also completely seals off natural air convection channels, preventing the effective dissipation of sweat and heat generated by the body through evaporation or diffusion. This creates a localized high-humidity and high-temperature environment within the confined space. Conventional solutions typically involve incorporating microporous breathable membranes into the fabric or installing manually adjustable vents in certain areas. However, these methods have significant drawbacks: when dealing with the large amounts of moisture generated during high-intensity work, the passive diffusion rate of the microporous breathable membrane is far lower than the rate at which the human body sweats, making it difficult to achieve rapid cooling. Manual vents, on the other hand, are prone to allowing external liquids to seep in under complex or extreme working conditions, compromising the overall waterproofness. Furthermore, due to the lack of forced ventilation, airflow relies solely on pressure differences, failing to eliminate stuffy, hot spots inside the trousers. This makes it difficult to achieve efficient temperature control and forced moisture removal while ensuring absolute waterproofing. Therefore, there is an urgent need for waterproof footwear and trousers with forced ventilation to address these issues. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a waterproof footwear and trousers with forced ventilation, comprising: a waterproof shoe body, a trouser body integrally connected to the waterproof shoe body, a sealed waist support for ventilation inside the trouser body, and a tight-fitting back strap, in order to solve the problems mentioned in the background art.

[0004] The technical solution of the present invention is implemented as follows: a waterproof shoe and trousers with forced ventilation, comprising: a waterproof shoe body, a trouser body for integral connection with the waterproof shoe body, a sealed waist support for ventilation inside the trouser body, and a tight-fitting back strap. The trouser body is provided at the upper end of the waterproof shoe body, and a set of sealed waist supports for improving waist support and forced ventilation is provided at the upper end of the trouser body. Two sets of tight-fitting back straps for wearing support are provided at the upper end of the sealed waist support.

[0005] The sealing waist support includes a support ring, air intake and exhaust components, and a cooling water circulation pipe. The upper rear side of the support ring is provided with a set of air intake and exhaust components for drawing in and expelling external air. The left and right sides of the support ring are hollow ring structures. The upper left side of the support ring is provided with a set of inlet tee for introducing external air and external cooling water. The front cross-section of the inlet tee is an inverted Y-shaped structure. The lower left and right sides of the inlet tee are provided with a set of flow equalization ports. Each set of flow equalization ports is provided with a set of inlet main pipe at the lower end. The inlet main pipe includes a set of air intake pipes and a set of water intake pipes. Each set of inlet main pipes is provided with three sets of internal fans for outputting cooling air inside the trouser body at the lower end.

[0006] First, put on the waterproof boots and pants. Adjust the tight straps to seal and securely support the waist. Then, turn on the inlet and outlet fans. Fresh air is drawn in from the outside through the air intake and exhaust components. The air and cooling water are evenly guided into the pants through the inlet tee and inlet manifold. Forced cold air is output through the inlet fans located at the bottom. At the same time, the outlet fans, together with the outlet pipe, outlet tee, and exhaust pipe, efficiently remove and expel the humid air and heat from the inside. Combined with the cooling water circulation pipe, a closed-loop temperature control is formed.

[0007] In a preferred embodiment, the bottom of the inlet fan is provided with a cooling water circulation pipe for guiding coolant into the pumping pipe. The front of the cooling water circulation pipe is connected to the bottom pumping fan. The front of the cooling water circulation pipe is provided with a pumping fan for extracting air from the inside of the pants on the same side. The number of pumping fans is the same as that of the inlet fan. The two pumping pipes on the same side are connected to each other. The upper end of the two pumping pipes is provided with a main pumping tee for collecting the air extracted from the inside of the pants. The upper end of the main pumping tee is located at the bottom of the front side of the support ring. The upper right side of the support ring is provided with a water pumping pipe for discharging circulating cooling water. The lower right side of the support ring is provided with an air pumping pipe for extracting air from the inside of the pants. The air pumping pipe and the water pumping pipe are connected to the right side of the air inlet and exhaust components.

[0008] After putting on waterproof shoes and pants and securing the waist support, the user activates the ventilation system. The internal fan draws cool air into the pants, while the bottom cooling water circulation pipe efficiently guides coolant into the extraction pipe. This coolant circulates through the connection with the bottom extraction fan. For air circulation, the extraction fan on the same side starts simultaneously, drawing out the hot and humid air from inside the pants. The air is then collected in the main extraction tee through two interconnected extraction pipes and finally discharged through the air intake and exhaust pipes located at the bottom front of the support ring. This creates a dual operating mechanism of liquid circulation cooling and forced gas exchange.

[0009] In a preferred embodiment, the inlet fan includes a semiconductor heat sink, a water inlet head, an air inlet head, and a fan body. The cooling zone of the semiconductor heat sink is located on one side of the fan body, and the heat dissipation zone of the semiconductor heat sink is located on the side connected to the water inlet head. A sealing cover is provided on the outside of the heat dissipation zone of the semiconductor heat sink, and a heat dissipation cavity is provided on the inside of the sealing cover. The inside of the water inlet head is connected to the inside of the heat dissipation cavity. The water inlet pipe and the air inlet pipe form a series structure with multiple sets of inlet fans on the same side. An air cavity is provided between the cooling zone of the semiconductor heat sink and the fan body. The air cavity is connected to the inside of the air inlet head. The main inlet pipe and multiple inlet fans on the same side are all located inside the trouser body. The extraction pipe and the extraction fan on the same side are all located inside the trouser body. The extraction fan has the same specifications as the inlet fan, and a debris-blocking mesh is provided on the inside of the trouser body.

[0010] After the user starts the external intake fan, air is drawn into the series-distributed internal intake fans through the intake pipe. The air enters the air chamber through the intake head and is rapidly cooled as it passes through the cooling zone of the semiconductor heat sink. Then, the fan body forces the air into the inside of the unit. At the same time, the water inlet head guides the cooling water into the heat dissipation chamber inside the sealed cover. The heat absorbed by the cooling zone is carried away by the heat dissipation zone of the semiconductor heat sink and circulated out through the water inlet pipe. During the air extraction process, the internal exhaust fan of the same specification draws out the hot and humid air inside. All air inlets and outlets are filtered through the inner filter screen to ensure the purity of the airflow.

[0011] In a preferred embodiment, the air intake and exhaust components include a rear cover and an exhaust pipe. The front side of the rear cover is provided with a rear frame for installing an exhaust fan and an intake fan. The left side of the rear frame is provided with an intake fan for introducing external air, and the right side of the rear frame is provided with an exhaust fan for forcibly expelling air from inside the pants.

[0012] In a preferred embodiment, the rear end of the rear frame is divided into an inlet area and an outlet area, corresponding to the rear side of the intake fan and the exhaust fan, respectively. The inlet area is equipped with a cooling spiral tube assembly for uniformly cooling the incoming and outgoing air. The cooling spiral tube assembly includes a cooling water pipe and spiral blades to increase the cooling contact surface. The inlet area is interconnected with the main inlet tee, its air inlet pipe is interconnected with the inlet area, and its water inlet pipe is interconnected with the external inlet. The outlet area is interconnected with the exhaust tee, and its exhaust pipe is interconnected with the outlet area. The system is interconnected with the external outlet. The external air intake fan draws fresh air into the intake area through the external outlet. Before passing through the main tee, the air passes through the cooling spiral tube assembly, where it is pre-cooled by the internal cooling water and the spiral blades with increased contact area. Then, it is sent into the trouser body through the intake pipe. At the same time, the external air intake fan forces the hot and humid air inside the trouser body to the exhaust area and out of the body through the exhaust pipe through the external outlet. The system also simultaneously guides the circulating cooling water from the external outlet to the outside through the water intake pipe.

[0013] In a preferred embodiment, the lower end of the trousers is provided with a set of threaded groove connectors that can be quickly separated from the waterproof shoe body. The inner side of the trousers is provided with an anti-abrasion flexible pad. The waterproof shoe body includes an anti-deformation shell, an anti-slip sole, and a waterproof connecting thread. The waterproof connecting thread is threadedly connected to the threaded groove connector. The front side of the waterproof shoe body is provided with an anti-deformation shell to improve the wear resistance and anti-deformation effect. The bottom of the anti-slip sole is provided with a set of anti-slip soles for anti-slip purposes. The bottom of the anti-slip sole is provided with stepped anti-slip and waterproof grooves, as well as anti-slip patterns with a herringbone cross-section.

[0014] In a preferred embodiment, the trousers include an outer waterproof layer, an outer thermal insulation layer, a nylon woven layer, an inner thermal insulation layer, and an inner waterproof layer. The outer waterproof layer has an outer thermal insulation layer inside to prevent external heat from entering the trousers. The outer thermal insulation layer is a high-density polyethylene film layer. The outer thermal insulation layer is a thermal insulation wadding pressed layer. The outer thermal insulation layer has a set of nylon woven layers inside to improve the deformation quality of the trousers. Several sets of inlet and outlet internal fans are embedded within the nylon woven layer. The nylon woven layer has an inner thermal insulation layer inside to prevent rapid heat dissipation from the inside of the trousers. The inner thermal insulation layer has an inner waterproof layer inside to provide waterproof protection to the inside. The inner waterproof layer and the outer waterproof layer are made of the same material. The inner thermal insulation layer and the outer thermal insulation layer are made of the same material.

[0015] First, the threaded connector at the bottom of the pants is screwed into the waterproof threaded connection of the waterproof shoe body. This simple threaded connection allows for a quick and secure connection between the pant leg and the shoe body. Meanwhile, the anti-deformation shell on the front of the shoe body and the stepped waterproof groove and herringbone anti-slip sole ensure wear resistance and strong grip when walking on complex terrain. Inside the pants, multiple layers of materials work together. External air is first blocked by the outer waterproof layer and the outer thermal insulation layer composed of a high-density polyethylene film. Then, it passes through the nylon woven layer with an embedded airflow fan. Finally, the inner thermal insulation layer and the inner waterproof layer maintain a stable internal temperature and provide secondary waterproof protection. The inner abrasion-resistant flexible pad enhances the comfort of skin contact.

[0016] After adopting the above technical solution, the beneficial effects of the present invention are: the structured layout of the sealed waist support realizes the precise diversion and forced circulation of air and cooling water, which can quickly reduce the internal temperature of the pants and remove the accumulated water vapor. It not only solves the common problem of stuffiness and dampness when wearing waterproof clothing, but also reduces the physical burden on the wearer through the support of the waist support, and improves the comfort and safety of working in special environments.

[0017] By constructing a linkage structure between the cooling water circulation pipe and the pumping system, a high degree of integration of water cooling and air cooling is achieved. This not only enhances the heat exchange efficiency, enabling the inside of the pants to quickly reach the ideal temperature, but also ensures that the airflow is evenly distributed inside the pants through the symmetrical pumping design, completely eliminating localized stuffy dead corners, enhancing the sweat-wicking and cooling capabilities of waterproof shoes and pants in the environment, and ensuring the wearer's physiological comfort.

[0018] By introducing semiconductor cooling technology and combining it with a water-cooled heat dissipation cavity, the traditional simple air cooling is upgraded to active cooling, realizing the output of cool air at a specific temperature. The series structure and the impurity-blocking mesh ensure the uniform distribution of the cooling effect and the stability of the system operation. While effectively preventing internal impurities from entering the fan, it improves the heat exchange efficiency, allowing the wearer to obtain a low temperature feel and a dry environment even in high temperature and high humidity environments.

[0019] By constructing an independent intake and exhaust flow separation zone design in the rear frame, physical isolation between intake pre-cooling and exhaust gas emission is achieved, avoiding mutual interference between internal and external airflows. Furthermore, the introduction of the cooling spiral tube assembly provides preliminary cooling before the air enters the internal circulation, reducing the cooling pressure on the internal fan, improving the overall heat exchange efficiency ratio, and ensuring that a low-temperature, dry, and highly efficient circulating microenvironment is maintained inside the trouser body under various complex environments.

[0020] By constructing a five-layer composite thermal insulation and waterproof structure, environmental adaptability is achieved, effectively isolating external temperature differences and preventing cold air leakage. The nylon woven layer's embedded support for the fan enhances the structural strength and durability of the pants. Combined with the quick-release connection mechanism of the integrated shoes and pants and the professional anti-slip sole, the entire protective system ensures waterproofing and efficient temperature control while also taking into account the flexibility and high comfort of wearing them.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-3 As the first embodiment of the present invention: a waterproof shoe and trousers with forced ventilation, comprising: a waterproof shoe body 1, a trouser body 2 for integral connection with the waterproof shoe body 1, a sealed waist support 3 for ventilation of the inside of the trouser body 2, and a tight-fitting back strap 4. The trouser body 2 is provided at the upper end of the waterproof shoe body 1, and a set of sealed waist supports 3 for improving waist support and forced ventilation of the user is provided at the upper end of the trouser body 2. Two sets of tight-fitting back straps 4 for wearing support are provided at the upper end of the sealed waist support 3.

[0039] The sealing waist support 3 includes a support ring 31, an air intake and exhaust component 32, and a cooling water circulation pipe 302. The upper rear side of the support ring 31 is provided with a set of air intake and exhaust components 32 for drawing in and expelling external air. The left and right sides of the support ring 31 are hollow ring structures. The upper left side of the support ring 31 is provided with a set of inlet tee 33 for introducing external air and external cooling water. The front cross-section of the inlet tee 33 is an inverted Y-shaped structure. The lower left and right sides of the inlet tee 33 are provided with a set of flow equalization ports. The lower end of each set of flow equalization ports is provided with a set of inlet main pipe 34. The inlet main pipe 34 includes a set of air intake pipe and a set of water intake pipe. The lower end of each set of inlet main pipe 34 is provided with three sets of inlet internal fans 35 for outputting cooling air inside the trouser body 2.

[0040] First, put on the waterproof shoes and pants. Adjust the tight straps 4 to make the waist support 3 securely support the waist. Then, turn on the inlet fan 35 and the exhaust fan 36. Fresh air is drawn in from the outside through the air intake and exhaust components 32. The air and cooling water are evenly guided into the pant body 2 through the inlet tee 33 and the inlet manifold 34. Forced cold air output is achieved through the inlet fan 35 distributed at the bottom. At the same time, the exhaust fan 36, together with the exhaust pipe 37, the exhaust tee 38 and the exhaust pipe 301, efficiently removes the humid air and heat from the inside and forms a closed-loop temperature control with the cooling water circulation pipe 302.

[0041] It can quickly reduce the internal temperature of the trousers and expel accumulated moisture, solving the common problems of stuffiness and dampness when wearing waterproof clothing. Furthermore, the lumbar support reduces the wearer's physical burden, improving comfort and safety during work in special environments.

[0042] Please see Figures 1-5 As a second embodiment of the present invention: A set of cooling water circulation pipes 302 for circulating coolant into the pumping pipe 37 is provided at the lower end of the bottom inlet fan 35. The front side of the cooling water circulation pipe 302 is connected to the interior of the bottom pumping fan 36. A set of pumping fans 36 for extracting air from the inside of the same side of the trouser body 2 is provided on the front side of the cooling water circulation pipe 302. The number of pumping fans 36 is the same as that of the inlet fan 35. The pumping fans 36 on the same side are connected to both sides of the pipe. The two sets of suction pipes 37 are interconnected. The upper end of the two sets of suction pipes 37 is provided with a set of suction tee 38 for collecting the suction air inside the trouser body 2. The upper end of the suction tee 38 is located at the bottom front side of the support ring 31. The upper right side of the support ring 31 is provided with a set of suction pipe 39 for discharging circulating cooling water. The lower right side of the support ring 31 is provided with a set of suction pipe 301 for extracting air from inside the trouser body 2. The suction pipe 301 and the suction pipe 39 are connected to the right side of the air inlet and outlet components 32.

[0043] After the user puts on waterproof shoes and pants and secures the waist support, the ventilation system is activated. The inlet fan 35 sends cooling air into the pant body 2. At the same time, the bottom cooling water circulation pipe 302 efficiently guides the coolant into the exhaust pipe 37 and achieves liquid circulation through the connection with the bottom exhaust fan 36. In terms of air circulation, the exhaust fan 36 on the same side is activated simultaneously to extract the hot and humid air from inside the pant body 2. The air is collected by the two sets of interconnected exhaust pipes 37 to the exhaust tee 38, and finally guided to the right side of the air intake and exhaust components 32 through the channel at the bottom front of the support ring 31 by the exhaust pipe 301 and the water intake pipe 39 and discharged from the body. This forms a dual operation mechanism of liquid circulation cooling and forced gas exchange.

[0044] By constructing a linkage structure between the cooling water circulation pipe 302 and the pumping system, a high degree of integration of water cooling and air cooling is achieved. This not only enhances the heat exchange efficiency, enabling the inside of the trouser body 2 to quickly reach the ideal temperature, but also ensures that the airflow is evenly distributed inside the trouser body 2 through the symmetrical pumping design, completely eliminating localized stuffy dead zones, enhancing the sweat-wicking and cooling capabilities of waterproof shoes and trousers in the environment, and ensuring the wearer's physiological comfort.

[0045] Please see Figures 1-5 As a third embodiment of the present invention: based on the description in the second embodiment, the inlet fan 35 includes a semiconductor heat sink 5a, a water inlet head 5b, an air inlet head 5c, and a fan body 5d. The cooling area of ​​the semiconductor heat sink 5a is located on one side of the fan body 5d, and the heat dissipation area of ​​the semiconductor heat sink 5a is located on the side connected to the water inlet head 5b. A sealing cover is provided on the outside of the heat dissipation area of ​​the semiconductor heat sink 5a, and a heat dissipation cavity is provided on the inside of the sealing cover. The inside of the water inlet head 5b is connected to the inside of the heat dissipation cavity. The water inlet pipe and the air inlet pipe form a series structure with multiple sets of inlet fans 35 on the same side. An air cavity is provided between the cooling area of ​​the semiconductor heat sink 5a and the fan body 5d. The air cavity is connected to the inside of the air inlet head 5c. The main inlet pipe 34 and multiple inlet fans 35 on the same side are all located inside the trouser body 2. The extraction pipe 37 and the extraction fan 36 on the same side are all located inside the trouser body 2. The extraction fan 36 has the same specifications as the inlet fan 35, and a debris-blocking mesh is provided on the inside of the trouser body 2.

[0046] After the user starts the external air intake fan 2e, air is introduced into the series-distributed internal intake fans 35 through the air intake pipe. The air enters the air chamber through the air intake head 5c and is rapidly cooled when it passes through the cooling zone of the semiconductor heat sink 5a. Then, the fan body 5d forces the air into the inside of the body 2. At the same time, the water inlet head 5b introduces cooling water into the heat dissipation chamber inside the sealed cover. The heat absorbed by the cooling zone is carried away through the heat dissipation zone of the semiconductor heat sink 5a and is circulated out through the water inlet pipe. During the air extraction process, the internal exhaust fan 36 of the same specification extracts the hot and humid air inside. All air inlets and outlets are filtered through the inner impurity filter to ensure the purity of the airflow.

[0047] By introducing semiconductor cooling technology and combining it with a water-cooled heat dissipation cavity, the traditional simple air cooling is upgraded to active cooling, realizing the output of cool air at a specific temperature. The series structure and the impurity-blocking mesh ensure the uniform distribution of the cooling effect and the stability of the system operation. While effectively preventing internal impurities from entering the fan, it improves the heat exchange efficiency, allowing the wearer to obtain a low temperature feel and a dry environment even in high temperature and high humidity environments.

[0048] Please see Figures 1-9 As a fourth embodiment of the present invention: based on the description in the second and third embodiments, the air intake and exhaust component 32 includes a rear cover 2a, a rear frame 2b, a motor 2c, an external exhaust fan 2d, an external intake fan 2e, an external inlet 2f, an external outlet 2g, a cooling spiral tube assembly 2h, an inner groove 2i, an exhaust storage chamber 2j, and an exhaust pipe 2k. A set of rear frame 2b for installing the external exhaust fan 2d and the external intake fan 2e is provided on the front side of the rear cover 2a. An external intake fan 2e for introducing external air is provided inside the left side of the rear frame 2b. A set of external exhaust fans 2d for forcibly exhausting the air inside the pants body 2 is provided inside the right side of the rear frame 2b.

[0049] The rear end of the rear frame 2b is divided into an inlet area and an outlet area, corresponding to the rear side of the intake fan 2e and the exhaust fan 2d, respectively. The inlet area is equipped with a cooling spiral tube assembly 2h for uniformly cooling the inlet and outlet air. The cooling spiral tube assembly 2h includes cooling water pipes and spiral blades that increase the cooling contact surface. The inlet area is interconnected with the inlet tee 33, and its air inlet pipe is interconnected with the inlet area. The water inlet pipe is interconnected with the outer inlet port 2f. The outlet area is interconnected with the exhaust tee 38, and the exhaust pipe 301 is interconnected with the outlet area. The water inlet pipe 39 is interconnected with the outer outlet. The internal components of 2g are interconnected. The external air intake fan 2e draws fresh air from the outside into the intake area through the external air intake port 2f. Before passing through the intake tee 33, the air passes through the cooling spiral tube assembly 2h, where it is pre-cooled by the internal cooling water and the spiral blades with increased contact area. Then, it is sent into the trouser body 2 through the intake pipe. At the same time, the external exhaust fan 2d draws the hot and humid air inside the trouser body 2 through the external air intake port 2g to the exhaust area and discharges it from the body through the exhaust pipe 301. The system also simultaneously guides the circulating cooling water from the external air intake port 2g to the outside through the water intake pipe 39.

[0050] By constructing an independent intake and exhaust flow separation zone design in the rear frame 2b, physical isolation between intake pre-cooling and exhaust gas emission is achieved, avoiding mutual interference between internal and external airflows. Furthermore, the introduction of the cooling spiral tube group 2h provides preliminary cooling before the air enters the internal circulation, reducing the cooling pressure on the internal fan, improving the overall heat exchange efficiency ratio, and ensuring that a low-temperature, dry, and highly efficient circulating microenvironment is maintained inside the trouser body 2 under various complex environments.

[0051] Please see Figures 1-3 As a fifth embodiment of the present invention: based on the description in the first embodiment, the lower end of the trouser body 2 is provided with a set of threaded groove connectors that can be quickly separated from the waterproof shoe body 1. The inner side of the trouser body 2 is provided with a wear-resistant flexible pad. The waterproof shoe body 1 includes a deformation-resistant outer shell 11, a non-slip sole 12, and a waterproof connecting thread 13. The waterproof connecting thread 13 is threadedly connected to the threaded groove connector. The front side of the waterproof shoe body 1 is provided with a deformation-resistant outer shell 11 for improving wear resistance and deformation resistance. The bottom of the non-slip sole 12 is provided with a set of non-slip soles 12 for non-slip. The bottom of the non-slip sole 12 is provided with stepped non-slip waterproof grooves and non-slip textures with a herringbone cross-section.

[0052] The trouser body 2 includes an outer waterproof layer 21, an outer thermal insulation layer 22, a nylon woven layer 23, an inner thermal insulation layer 24, and an inner waterproof layer 25. The outer waterproof layer 21 has an outer thermal insulation layer 22 inside to prevent external heat from entering the trouser body 2. The outer thermal insulation layer 22 is a high-density polyethylene film layer and a thermal insulation wadding pressed layer. Inside the outer thermal insulation layer 22 is a set of nylon woven layers 23 to improve the deformation quality of the trouser body 2. Several sets of inlet internal fans 35 and several sets of outlet internal fans are embedded in the nylon woven layers 23. The inner side of the nylon woven layers 23 has a design to prevent rapid temperature changes inside the trouser body 2. The inner insulation layer 24 is distributed, and an inner waterproof layer 25 is provided on the inner side of the inner insulation layer 24 to provide inner waterproof protection. The inner waterproof layer 25 is made of the same material as the outer waterproof layer 21, and the inner insulation layer 24 is made of the same material as the outer insulation layer 22. First, the threaded connector at the lower end of the pant body 2 is screwed into the waterproof connection thread 13 of the waterproof shoe body 1. The pant leg and the shoe body are quickly and stably connected through a simple threaded connection. At the same time, the anti-deformation shell 11 on the front of the shoe body is combined with the stepped waterproof groove and herringbone anti-slip pattern of the sole to ensure wear resistance and strong grip when walking in complex terrain.

[0053] Inside the pants body 2, multiple materials work together. External air is first blocked by the outer waterproof layer 21 and the outer thermal insulation layer 22 composed of high-density polyethylene film. Then it passes through the nylon braided layer 23 with an embedded inlet and outlet airflow fan. Finally, the inner thermal insulation layer 24 and the inner waterproof layer 25 maintain a stable internal temperature and provide secondary waterproof protection. The inner abrasion-resistant flexible pad improves the comfort of skin contact.

[0054] By constructing a five-layer composite thermal insulation and waterproof structure, environmental adaptability is achieved, effectively isolating external temperature differences and preventing cold air leakage. The nylon woven layer 23 provides embedded support for the fan, enhancing the structural strength and durability of the trouser body 2.
