Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] refer to Figure 1 Wading trousers are essential protective clothing worn during aquaculture operations or fishing, serving a waterproof function to ensure the comfort and stability of the workers' physiological environment and support the smooth operation of various fishing activities. However, existing wading trousers on the market do not have a life-saving function. Therefore, fishery workers wearing wading trousers while wading need to wear life jackets for safety, which is inconvenient. Wading trousers with life-saving functions have overly large life-saving airbags, which, when worn, resemble a vest covering the entire upper body, making operation very difficult. Therefore, this application provides a life-saving wading trouser 10 that is convenient to wear, comfortable, easy to operate, and has good life-saving performance. The life-saving wading trouser 10 is in the form of a one-piece suit, including a trouser body 100, a garment body 200, and an inflatable component 300. The trouser body 100 is leg-shaped and worn on the lower body; the garment body 200 is connected to the trouser body and worn on the upper body; the inflatable component 300 is connected to the garment body 200 and serves an inflation function.

[0038] Specifically, please refer to Figure 1The garment 200 includes a bib 210, a wearable component 220, and an air bag 230. The bib 210, as the main body of the garment, is worn on the upper body. The bib 210 has a lower end 211 connected to the trousers 100 and an upper end 212 away from the trousers 100. The lower end 211 of the bib 210 is connected to the trousers 100, and the upper end of the bib 210 is worn on the upper body via the wearable component 220. The air bag 230 has a connecting end 231, a floating end 232, and a first air bladder cavity 233 located between the connecting end 231 and the floating end 232. The connecting end 231 is heat-pressed and bonded to the bib 210. The floating end 232 detaches from the bib 210 and floats on the water surface after the first air bladder cavity 233 inflates. It is worth noting that, for the air bag 230, except for the location of the connecting end 231, the other boundary edges of the first air bladder cavity 233 belong to the floating end 232. The inflatable component 300 is connected to the garment body 200 and communicates with the first airbag cavity 233 to inflate the first airbag cavity 233.

[0039] The life-saving waders 10 provided by this utility model have an air bag 230 heat-pressed onto a bib 210. When inflated, the air bag 230 forms a first air chamber 233, which functions as a rescue airbag. Workers rely on this first air chamber 233 to float to the surface, avoiding drowning, thus giving the life-saving waders 10 a life-saving function. When the air bag 230 deflates, the first air chamber 233 collapses, and the air bag 230 rests against the outside or inside of the bib 210, making it convenient for the user to wear the waders 10 and work in the water. Furthermore, because the connecting end 231 of the air bag 230 is heat-pressed and bonded to the bib 210, the first air chamber 233 is not easily detached from the body. Therefore, the life-saving waders 10 of this application, while ensuring safety, has a simple and lightweight structure, is convenient for users to wear and work in the water, and has great practicality.

[0040] Preferably, in one embodiment, in conjunction with reference to Figures 1-3The airbag 230 includes a first material layer 234 and a second material layer 235 that enclose a first air bladder cavity 233. At the floating end 232, the edges of the first material layer 234 and the second material layer 235 are integrally connected. This integral connection can be achieved through methods including, but not limited to, heat-pressing bonding and integral molding. At the connecting end 231, the edges of the first material layer 234, the second material layer 235, and the upper end 212 are overlapped and heat-pressed together to seamlessly bond the connecting end 231 of the airbag 230 to the upper end 212 of the bib 210. When the airbag 230 is inflated to form the first air bladder cavity 233, the floating height of the first air bladder cavity 233 is exactly level with the upper end 212, and the worker's head floats above the water, which is just the height at which drowning is expected, facilitating the worker's self-rescue and call for help. It should be noted that the position of the connecting end 231 of the air bag 230 to the bib 210 is not limited, as long as it is connected between the lower end 211 and the upper end 212.

[0041] Preferred, Reference Figures 1-5 In one embodiment, Figure 1 As illustrated, the bib 210 also includes a second air bladder cavity 213 located between the lower end 211 and the upper end 212, and the second air bladder cavity 213 is connected to the first air bladder cavity 233. (Combined) Figure 4 and Figure 5 The second airbag cavity 213 includes an outer material layer 214 and an inner material layer 215; combined with Figure 3 and Figure 5 At a portion of the boundary of the second airbag cavity 213, the outer material layer 214 and the inner material layer 215 are thermally bonded together; at another portion of the boundary of the second airbag cavity 213, the outer material layer 214 and the inner material layer 215 enclose and form an opening 216. Figure 4 (As shown). At the opening 216, the first material layer 234 and the outer material layer 214 are heat-pressed together, and the second material layer 235 and the outer material layer 214 are heat-pressed together, forming a channel connecting the first airbag cavity 233 and the second airbag cavity 213. Here, the boundary of the second airbag cavity 213 refers to the upper end 212 of the bib 210. It should be noted that both the connected first airbag cavity 233 and the second airbag cavity 213 are used as rescue airbags, increasing the buoyancy of the rescue airbags. Therefore, the second airbag cavity 213 on the bib 210 further improves the safety of the life-saving waders 10. In other embodiments of this application, the presence or absence of the second airbag cavity 213 is not limited, and the first airbag cavity 233 can meet the safety and life-saving requirements of the life-saving waders.

[0042] Preferably, in conjunction with reference Figure 4 and Figure 5In one embodiment, the outer material layer 214 is seamlessly joined end to end along the circumference of the human body to form a cylindrical structure, and the inner material layer 215 is also seamlessly joined end to end along the circumference to form a cylindrical structure. The outer material layer 214 and the inner material layer 215 are seamlessly bonded at the upper end 212 and at the lower end 211, and the second airbag cavity 213 is connected end to end along the circumference. In this embodiment, there is one second airbag cavity 213. The bib 210 consists of two layers of fabric with basically the same size and shape (which can basically overlap and fit together, and there will be some rough edges at the heat-pressed bonding position), namely the outer material layer 214 and the inner material layer 215. Therefore, the upper and lower ends of the outer material layer 214 and the inner material layer 215 correspond to the upper end 212 and the lower end 211, respectively. By seamlessly bonding the corresponding overlapping edges of the outer material layer 214 and the inner material layer 215, a second airbag cavity 213 is formed. Here, the overall structure formed by bonding the outer material layer 214 and the inner material layer 215 has two states: in the deflated state, it functions as a bib 210; in the inflated state, it forms a bulging second airbag cavity 213, serving both a wearable and life-saving function. Furthermore, there are two air bags 230, each connected to opposite sides of the upper end 212. The two air bags 230 are located on the front and back sides or left and right sides of the bib 210, ensuring relative balance of the body and preventing tipping after inflation. It should be noted that in other embodiments of this application, the number and connection position of the air bags 230 are not limited.

[0043] It should be noted that the position where the outer material layer 214 and the inner material layer 215 are bonded together is not limited. In other embodiments, the outer material layer 214 or the inner material layer 215 is simply part of the bib, and the second air bladder cavity 213 is formed in a bulge shape on the outside or inside of the bib 210. In this case, the outer material layer 214 and the inner material layer 215 are bonded at other positions on the bib 210 (different from the upper end 212 and the lower end 211). Furthermore, the extent to which the second air bladder cavity 213 encircles the side of the body is not limited; it can encircle half a circle or a full circle. Encircling half means that the second air bladder cavity 213 is provided on either the front chest portion or the back portion of the bib 210. Of course, it can also encircle less. In practice, the second air bladder cavity 213 generally encircles at least the front chest portion. In this case, the inflator 300 is also located on the corresponding front chest portion of the bib 210 for user convenience in inflating the inflator 300.

[0044] Preferably, in one embodiment, reference Figure 6At the lower end 211, the waist edge of the trouser body 100, the edge of the inner material layer 215, and the edge of the outer material layer 214 are overlapped and seamlessly bonded by heat pressing to connect the trouser body 100 to the bib 210. Here, the stacking order of the waist edge of the trouser body 100, the edge of the inner material layer 215, and the edge of the outer material layer 214 is not limited, as long as three layers are stacked. It should be noted that the heat pressing process can simultaneously press and bond multiple layers of materials together. In this embodiment, not only is the connection between the trouser body 100 and the bib 210 completed, but the bonding of the second airbag cavity 213 at the lower end 211 is also completed. Of course, any method that can achieve the connection between the trouser body 100 and the bib 210 should be included.

[0045] Preferably, refer to Figure 7 In one embodiment, the inflation component 300 includes an air nozzle 310, which is disposed on the outer surface of the air bag 230 and communicates with the first air bladder cavity 233 to inflate the first air bladder cavity 233. Specifically, the air nozzle 310 includes an air tube 311 and a one-way valve 312. One end of the air tube 311 is connected to the upper end 212 and communicates with the first air bladder cavity 233. The one-way valve 312 is disposed inside the air tube 311, and the inlet of the air tube 311 faces longitudinally upward to facilitate inflating by the user. Here, the air nozzle 310 also includes a plug 313 for sealing the opening of the air tube 311. When inflation is not required, the plug 313 can be used to block the air tube 311 to prevent water and dust from entering.

[0046] Preferably, refer to Figure 8 In one embodiment, the inflatable component 300 includes an automatic inflation device 320, which is located at the upper end 212 and communicates with the second airbag cavity 213 to automatically inflate the second airbag cavity 213. Here, the automatic inflation device 320 includes a gas cylinder 321 and a water-reactive valve 322. The gas cylinder 321 communicates with the second airbag cavity 213 through the water-reactive valve 322. The water-reactive valve 322 contains a water-soluble tablet, a compression spring, and a firing pin. The top post at the front end of the compression spring separates from the firing pin due to the obstruction of the water-soluble tablet, allowing for rapid opening of the gas cylinder 321 for inflation after the object falls into water. A manual pull rope 323 is also provided on the water-reactive valve 322 for manual inflation control.

[0047] Preferably, in one embodiment (not shown), the connecting end 231 is heat-pressed and bonded to the upper end 212. When the first airbag cavity 233 is not inflated, the floating end 232 rests against the outside of the bib 210 and is attached to the lower end 211 to prevent the airbag 230 from floating up when not in use, thus hindering underwater operations. The attachment method includes, but is not limited to, Velcro, magnetic attachment, etc. After the first airbag cavity 233 is fully inflated, the floating end 232 tilts up to float on the water surface. It should be noted that in this application, the position of the connecting end 231 heat-pressed and bonded to the bib 210 is not limited, nor is it limited whether the floating end 232 is attached to the bib 210.

[0048] Preferably, in conjunction with reference Figure 9 and Figure 10 In one embodiment, the first material layer 234 and the second material layer 235 are seamlessly joined end-to-end in the circumferential direction to form a cylindrical structure. The first material layer 234 and the second material layer 235 are seamlessly bonded circumferentially on the side away from the bib 210, and seamlessly bonded circumferentially on the side connected to the bib 210. The first airbag cavity 233 is connected end-to-end in the circumferential direction to form a whole, thereby forming a circumferentially encircling chamber.

[0049] In one embodiment, reference Figure 11 The first material layer 234 is seamlessly joined end-to-end in a cylindrical structure along the circumference. The size of the first material layer 234 is larger than that of the second material layer 235. There are multiple second material layers 235 arranged within the boundary area of ​​the first material layer 234 (here, the boundary area refers to the planar outline of the first material layer 234). Each second material layer 235 and the first material layer 234 form a first airbag cavity 233. The number of first airbag cavities 233 is the same as the number of second material layers 235. The multiple first airbag cavities 233 are connected by air passages, making all the first airbag cavities 233 interconnected as a whole. It should be noted that, firstly, the first material layer 234 and the second material layer 235 are relative. In other embodiments, the number and size of the first material layer 234 and the second material layer 235 can be interchanged to form multiple first airbag cavities 233. In addition, the multiple first airbag cavities 233 can be arranged circumferentially along the human body or longitudinally (vertically) along the human body.

[0050] Preferably, refer to Figure 12In one embodiment, there are multiple air bags 230 to form multiple first air bladder cavities 233. These first air bladder cavities 233 are distributed circumferentially around the periphery of the bib 210, unfolding in a petal-like pattern with the bib 210 as the center. At the connecting end 231, the bib 210 has a circumferentially connected annular air passage 217. Each first air bladder cavity 233 is connected to the annular air passage 217, so that all the first air bladder cavities 233 are connected as a single unit. It should be noted that the annular air passage 217 can be formed inside the bib 210 or can be an external air tube of the bib 210. Therefore, in this application, any arrangement that ensures all the first air bladder cavities 233 are connected as a single unit through the annular air passage 217 should be included.

[0051] It should be noted that when there are multiple first airbag cavities 233, the number of multiple first airbag cavities 233 includes at least a first cavity and a second cavity. The first cavity is connected to the front chest position of the bib 210, and the second cavity is connected to the back position of the bib 210. When the first airbag cavities 233 are inflated, the worker can maintain longitudinal balance and avoid tipping over. It should also be noted that in other embodiments, the number of first airbag cavities 233 can be two or more, as long as they include a first cavity and a second cavity, and are sufficient to keep the user from floating up or tipping over.

[0052] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
