Therefore, the staff involved must wear protective clothing to prevent dust from entering the protective clothing to prevent dust. In particular, it is necessary to prevent workers from inhaling dust into the body.

When the staff wears the protective clothing, they must immediately fill the air into the protective clothing so that there is enough oxygen-containing air in the protective clothing for the staff to breathe. Therefore, it is an important basic requirement to be able to quickly flush gas into protective clothing. A protective device for guiding air delivery is provided in the protective garment, which guides the air to the limbs. The pipeline device is formed by two upper and lower plastic sheets which are bonded to each other to form a long flat tube. When the protective clothing is stored in an environment with a high humidity temperature, the upper and lower sheets may stick to each other, causing the pipes to be closed, which seriously affects the operation of filling the air into the protective clothing.

In order to prevent the high pressure generated by the local position of the protective clothing caused by the action of the staff during work, the human body health is harmful, that is, the check valve device is provided, and the gas causing the instantaneous high pressure can be discharged outside the protective clothing.

The fastening positions of the left and right two fastening pieces 1621 and 1622 of the sealing piece 162 are offset from the position of the zipper 161, so that the zipper head 1611 of the zipper 161 does not abut against the left and right two fastening pieces 1621 and 1622. The position is fastened without causing the zipper head 1611 to open the left and right two cleats 1621 and 1622 and leaking air.

Please refer to Figure 3 and Figure 5. The protective clothing 10 is provided with a gas input port 17 which can be connected to a gas output pipe of a gas output device (not shown), feeds an oxygen-containing gas into the protective clothing 10, and causes the protective clothing 10 The air pressure inside is greater than the air pressure in the working environment. The gas output device can be an air compressor or a powered aerator. The inner end of the gas inlet port 17 is connected to a flat gas delivery line 20 which directs the oxygen-containing gas to the limb portions 12, 13, 14, 15 of the protective garment 10. Please refer to Figure 6. The gas delivery line 20 is a flat tube formed by bonding the upper and lower plastic sheets 21, 22 to each other with both sides joined together. The flat gas delivery line 20 is provided with a hose 30 extending in the gas conveying direction, so that the upper and lower sheets 21, 22 of the gas delivery line 20 are separated by the hose 30 without The upper and lower sheets 21 and 22 are bonded to each other by the protective clothing in a folded state and in an environment where the temperature and humidity are too high. This ensures that the gas delivery line 20 is in a clear state, so that the oxygen-containing gas can be quickly delivered to the limb portions 12, 13, 14, 15 of the protective clothing 10 and filled with the internal space of the protective clothing 10.

Please refer to Figure 7 and Figure 8. The hose 30 is provided with a spiral slit 31 extending from the top to the bottom. When the oxygen-containing gas enters the hose 30, the pressure of the gas expands the slit 31, allowing the gas to be charged into the gas delivery line 20 from the slit 30 without affecting the gas delivery rate. Four flat hoses 30 are bored in the flat gas delivery line 20, and the four hoses 30 extend from the inner end of the gas inlet port 17 to the limb portions 12, 13, 14, 15 respectively.

The staff will move the position during the work, and the hand and the head will also have movements, and some actions will squeeze the gas to cause an instantaneous local high pressure. In order to avoid the discomfort of the worker caused by the high pressure, the protective clothing 10 is provided with a pressure relief device 40 on the head and the back to discharge the gas which causes an instantaneous high pressure. The protective garment 10 is provided with a pocket 18 to house the pressure relief device 40.

Please refer to Figure 9 and Figure 10. The pressure relief device 40 includes a pressure relief valve 41 and an air bearing seat 42. The pressure relief valve 41 includes a first sheet 411 and a second sheet 412. The first sheet 411 has a through hole 413 which is in close contact with the pressure release opening 181 of the protective clothing 10. The second sheet 412 covers the first sheet 411, and its four ends are fixed to the four ends of the first sheet 411 to close the pressure relief 181 port. The pressure relief opening 181 of the protective garment 10 is provided with a loop of film 182 which prevents gas escape within the protective garment 10, as shown in FIG. Only when an instantaneous high pressure occurs in the protective garment 10 can the second sheet 412 be opened to vent the gas.

The front end of the air guide seat 42 is provided with at least four rods 421 to prevent deformation of the front end opening. The air guide seat 42 can be inserted into the pocket 18 of the protective garment 10, and the pressure relief valve 41 is introduced into the air guide seat 42. When the pressure relief valve 41 discharges air, a swelling phenomenon occurs between the first sheet 411 and the second sheet 412 to smoothly discharge the air. The inner space of the air guide seat 42 is sufficient to allow the first sheet 411 and the second sheet 412 to perform an inflation expansion.

The air guide seat 42 includes a bottom plate 423 of a top plate 422. The rear end of the top plate 422 is provided with four through holes 424 capable of guiding the gas. The gas discharged from the pressure relief valve 41 can flow from the four perforations 424 to the top surface of the air guide seat 42 to prevent all of the exhaust gas from affecting the inflation state of the first sheet 411 and the second sheet 412. The bottom edge of the bottom plate 423 is provided with a notch 425. The pressure relief port 181 of the protective garment 10 is located within the recess 425.

After the staff wears the protective clothing 10, it must be ensured that the protective clothing 10 has no holes or cracks. If the protective clothing 10 is leaking due to cracks or cracks, it may endanger the safety or health of the workers. Please refer to Figure 5. The protective garment 10 of the present invention is provided with a detecting hole 19 and a plug body 191 capable of closing the detecting hole 19. The plug body 191 and the outer wall of the detecting hole 19 are connected by a flexible belt body 192, so that the plug body 191 and the protective clothing 10 are integrally connected. Before the worker enters the work place, the plug body 191 is opened, and a pressure measuring device (not shown) is inserted from the detecting hole 19 to detect the pressure inside the protective clothing 10. When the pressure measured by the pressure measuring device is in a constant pressure state, it means that the protective clothing 10 is airtight. After the detection work is completed, the plug body 191 is closed to close the detecting hole 19. The protective garment 10 may further be provided with a tearable sealing sheet 193 which is wrapped around the detecting hole 19 and the plug body 191. Before the sealing sheet 193 is not torn, the outside air cannot enter the space between the sealing sheet 193 and the protective clothing 10. The staff member can choose whether to inspect the protective clothing 10 before entering the workplace. If the protective garment 10 is selected for inspection, the sealing sheet 193 is torn open for inspection. If it is selected not to detect the protective garment 10, it is not necessary to tear the sealing sheet 193.

The air-permeable protective clothing provided by the present invention uses a hose having a spiral slit penetrating in a flat gas delivery line to keep the gas delivery line unobstructed. The invention is further provided with a detection hole and an air bearing seat provided at the pressure relief valve. The inspection hole allows a safety inspection of the protective clothing before the worker enters the workplace. The air guide seat ensures that the pressure relief valve can operate normally.
