The axis of the automatic inflator 300 is parallel to the vertical direction, i.e., the automatic inflator 300 is vertically erected relative to the human body to increase the water wading height of the operator. It should be noted that in other embodiments, the axis of the automatic inflator 300 can also be inclined to the vertical direction, as long as the water-encountering trigger part 320 is vertically higher than the gas cylinder 310.

[0038] Preferably, referring to Figure 2 and Figure 3 The upper shielding part 420 is integrally connected with the bib 210 by hot-pressing adhesion. The upper shielding part 420 and the lower limiting part 410 are integrally molded by injection molding. Furthermore, Figure 3 It is illustrated that the overall shape of the waterproof cloth 400 is a convex character. The edges of the left and right sides of the lower part of the convex character and the upper edge of the convex character are hot-pressing adhered to the bib 210 to form the water-avoiding groove 430 in communication with the upper and lower sides. The forming process of the water-avoiding groove 430 is convenient and firm. It should be noted that in other embodiments of the present application, for example, the edges of a waterproof cloth 400 with an arbitrary shape are integrally processed and connected to the bib 210. Two slits or two holes are cut on the waterproof cloth 400. The water-avoiding groove 430 in communication with the upper and lower sides can also be formed. Therefore, in the present application, the integral connection method of the waterproof cloth 400 and the bib 210 is not limited. The shape of the waterproof cloth 400 is not limited. The integral connection method between the parts of the waterproof cloth 400 is also not limited.

It should be noted that the closed part corresponds to the water inlet hole 321 of the water-encountering triggering part 320. When the water level outside the water-avoiding groove 430 reaches the upper end of the water-avoiding groove 430, the water flows into the water-avoiding groove 430 through the water inlet 440, and then the water level of the water-avoiding groove 430 reaches the water inlet hole 321, and the water flows into the water-encountering triggering part 320 through the water inlet hole 321 to trigger the gas cylinder 310 to inflate the airbag chamber 213. In order to further improve the water level, the water inlet hole 321 is arranged on the end surface of the water-encountering triggering part 320; in order to speed up the inflation of the airbag chamber 213 and improve the safety and life-saving guarantee, the number of water inlet holes 321 is increased to improve the water inflow and speed up the dissolution (tablet dissolution) of the water-encountering triggering part 320. In addition, in this application, without considering the further improvement of the water level, the position of the water inlet 440 is not limited, and it only needs to be arranged on the water-avoiding groove 430.

[0040] Preferably, referring to Figure 2 In an embodiment, the number of water inlets 440 is two, and the two water inlets 440 are located on the left and right sides of the upper shielding part 420. This design can improve the water inflow speed on the one hand, and reduce the processing difficulty on the other hand, because only the hot-pressing of one side edge of the upper shielding part 420 on the apron 210 is needed to form two symmetrical water inlets 440. The above processing operation is better than one or more than two water inlets 440. It should be understood that without considering the processing difficulty, the number of water inlets 440 is not limited.

[0041] Preferably, referring to Figure 2 In an embodiment, the life-saving wading pants 10 further comprises a fixing cloth 500 which is integrally connected to the apron 210 (hot-pressing adhesion, etc.) on the opposite two side edges to form a fixing through groove 510.

The fixing through groove 510 is opposite to the water-avoiding groove 430 along the axial direction, so as to further stably fix the entire automatic inflation device 300 on the apron 210. It should be understood that without considering the stability of the connection between the automatic inflation device 300 and the apron 210, whether the fixing cloth 500 and the fixing through groove 510 are arranged or not is not limited.

[0042] Preferably, referring to Figure 2 The automatic inflation device 300 further comprises a pull rope 330 arranged between the gas cylinder 310 and the water-encountering triggering part 320. The pull rope 330 is exposed and located between the water-avoiding groove 430 and the fixing through groove 510, so that the operating personnel can manually pull the pull rope 330 to trigger the gas cylinder 310 to inflate the airbag chamber 213 when encountering danger, so as to realize the manual control of the automatic inflation device 300 to inflate the airbag chamber 213 and achieve the purpose of life-saving.

[0043] Preferably, in combination with reference to Figure 1 and Figure 2 In an embodiment, the waterproof cloth 400 is arranged on the outer surface of the apron 210, and the water inlet hole 321 is located at the upper end 212 of the waterproof cloth 400, so as to improve the water wading height of the worker. Therefore, the life-saving wading pants 10 not only has the life-saving function and safety guarantee, but also improves the life-saving wading height and ensures normal operation under the premise of safety guarantee.
