The sight glass 11 is mounted on the hood 10 in a fixed or detachable manner. Specifically, it can be fixedly connected to the hood 10 by sealing with a sealing strip or by heat fusion welding, or detachably connected by using hook and loop fasteners. The one-way valve 12 ensures that gas can only flow from the inside of the protective suit 100 to the outside, and cannot enter the protective suit 100 from the outside, thus preventing harmful gases, dust, liquid mist, etc. from entering the protective suit 100.

[0025] refer to Figure 3 and Figure 4 As shown, the air circuit structure 30 includes a three-way valve 31, a distribution pipe 32 connected to the outlet end of the three-way valve 31, and a first air supply pipe 33 and a second air supply pipe 34 connected to the inlet end of the three-way valve 31. The distal ends of the first air supply pipe 33 and the second air supply pipe 34 are connected to an air supply device. The air supply device supplies fresh air to the three-way valve 31 through the first air supply pipe 33 or the second air supply pipe 34, and the fresh air enters the interior of the protective suit 100 through the three-way valve 31 and the distribution pipe 32. The three-way valve 31 is detachably connected to the protective suit 20. In this embodiment, the three-way valve 31 is fastened to the protective suit 20 by a waist belt.

[0026] In some other embodiments, the first gas pipe 33 and the second gas pipe 34 are further provided with a protective layer with fine steel wires to prevent the first gas pipe 33 and the second gas pipe 34 from breaking due to mechanical action.

[0027] Combination Figure 3 As shown, the three-way valve 31 has a first air inlet pipe 311 connected to the first air supply pipe 33 and a second air inlet pipe 312 connected to the second air supply pipe 34 at its air inlet end. The second air inlet pipe 312 is approximately L-shaped. The axis of the horizontal portion of the second air inlet pipe 312 is perpendicular to the axis of the first air inlet pipe 311, and the axis of the vertical portion of the second air inlet pipe 312 is parallel to the axis of the first air inlet pipe 311. The second air inlet pipe 312 is located on one side of the first air inlet pipe 311, and the end of the first air inlet pipe 311 away from the valve body is flush with the end of the second air inlet pipe 312 away from the valve body.

[0028] In some embodiments, a straight connector 313 is provided between the first intake pipe 311 and the first air supply pipe 33, and between the second intake pipe 312 and the second air supply pipe 34, thereby facilitating quick disassembly and connection between the first intake pipe 311 and the first air supply pipe 33, and between the second intake pipe 312 and the second air supply pipe 34. The straight connector 313 can be a quick-connect self-locking straight connector or a threaded straight connector.

[0029] Combination Figure 3 As shown, the air inlet of the air distribution pipe 32 is connected to the air outlet of the three-way valve 31. The air outlet of the air distribution pipe 32 is equipped with a first air outlet pipe 321, and a second air outlet pipe 322 is provided on one side of the first air outlet pipe 321. The first air outlet pipe 321 is connected to the headgear 10 of the protective suit 100 via a flexible hose 323, allowing the worker to breathe fresh air. The second air outlet pipe 322 is connected to the protective clothing 20 via another flexible hose 323, accelerating the gas flow inside the protective clothing 20, reducing the temperature and humidity inside the protective clothing 20, thereby improving the worker's wearing experience. In some embodiments, the first air outlet pipe 321 and the second air outlet pipe 322 are also equipped with rotary switches 325 for adjusting the pipe opening and closing and the airflow magnitude.

[0030] In some embodiments, the first vent pipe 321 is connected to the side of the headgear 10 away from the sight glasses 11 by a flexible hose 323, so as to prevent the flexible hose 323 from interfering with the worker's vision.

[0031] Combination Figure 4 As shown, in some other embodiments, a vortex tube 324 is also connected between the second vent pipe 322 and the hose 323 to regulate the temperature of the gas entering the protective suit 20. When the ambient temperature is high, the hose 323 is connected to the cold air end of the vortex tube 324 to reduce the temperature of the gas entering the protective suit 20; when the ambient temperature is high, the hose 323 is connected to the hot air end of the vortex tube 324 to increase the temperature of the gas entering the protective suit 20.

[0032] Combination Figure 1-4 As shown, when workers wear protective clothing 100 to work in adverse environments, the air supply device introduces fresh air into the protective clothing 100 through the air passage structure 30. The three-way valve 31 is in a single-operation state; gas can enter the three-way valve 31 through the first air supply pipe 33, but gas cannot enter the three-way valve 31 through the second air supply pipe 34. The gas entering the three-way valve 31 enters the protective clothing 100 through the diversion pipe. A portion of the gas enters the headgear 10 of the protective clothing 100 through the first air outlet pipe 321 and the hose 323 for the worker to breathe; the other portion of the gas enters the protective suit 20 through the second air outlet pipe 322 and another hose 323, accelerating the gas flow within the protective suit 20, reducing the temperature and humidity within the protective suit 20, thereby improving the worker's wearing experience. Due to the complex working environment, one of the air supply pipes 33 and 34 may become blocked or ruptured due to unforeseen circumstances. In such cases, workers can adjust the three-way valve 31 to supply air to the protective suit 100 using the other air supply pipe. For example, if the first air supply pipe 33 becomes blocked or ruptured and cannot supply air to the protective suit 100, workers can adjust the three-way valve 31 to supply fresh air to the protective suit 100 using the second air supply pipe 34, thereby fully protecting the health and safety of workers.
