Description

Technical Field

[0001] This invention relates to the field of chemical protective clothing technology, specifically to airtight polymer membrane chemical protective clothing. Background Technology

[0002] Chemical protective suits are one-piece suits made of special protective materials, used to prevent toxic gases, liquids, dust and other harmful substances from entering the human body. Their structure typically includes a sealed hood, a bodysuit, gloves and boot covers, with components connected by zippers, hooks and loops, or buckles. They are suitable for high-risk scenarios such as chemical plants, firefighting operations, and nuclear contamination, and their core function is to create a physical barrier to ensure the wearer's safety.

[0003] Current chemical protective suits suffer from several drawbacks: the seals at component joints are prone to failure, they rely on traditional buckles and zippers which are susceptible to air leakage, and the suits themselves often lack sufficient heat dissipation during use, causing users to feel stuffy and uncomfortable. Additionally, the fabric protection is limited, making it difficult to repair once damaged, and it is also prone to dampness due to poor breathability. Overall, the suits have weak airtightness and lack multi-layered protection. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an airtight polymer membrane chemical protective suit, which solves the problems mentioned in the background technology, such as easy failure of sealing at component connections, reliance on traditional buckles and zippers leading to air leakage, insufficient heat dissipation during use causing users to feel stuffy and uncomfortable, single-layer fabric protection that is difficult to repair after damage, poor breathability and easy to get damp, weak overall airtightness, and lack of multi-layer protection.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an airtight polymer membrane chemical protective suit, comprising a hood, the bottom of which is provided with a first sealing element A, the bottom of which is adsorbedly connected to a first sealing element B, the bottom of which is provided with a one-piece top, the upper left and right sides of which are provided with sleeves, the cuffs of which are provided with a second sealing element A, the other end of which is adsorbedly connected to a second sealing element B, the other end of which is provided with a glove, the bottom of which is provided with one-piece trousers, the bottom of which is provided with one-piece boots, the back of which is provided with a backpack, the top opening of which is provided with a filtering mechanism, the inner wall of which is provided with a ventilation mechanism directly below the filtering mechanism, and the bottom and rear outer wall of which are connected with heat dissipation mechanisms.

[0006] More preferably, the first sealing element A includes a first insert, the top end of the first insert is located at the bottom end of the headgear, the outer wall of the first insert is provided with a first sealing layer, and the bottom end of the first insert is provided with a first magnetic piece A.

[0007] More preferably, the first sealing element B includes a first slot, and the bottom wall of the first slot is provided with a first magnetic piece B. The first magnetic piece A and the first magnetic piece B attract each other, and the first insert and the first slot engage with each other.

[0008] More preferably, the second sealing element A includes an insert ring seat, which is sleeved on the cuff of the sleeve. The annular inner wall of the insert ring seat is provided with a second sealing layer, and a second magnetic piece A is provided at one end of the insert ring seat near the cuff of the sleeve.

[0009] More preferably, the second sealing element B includes a slot ring seat, which is sleeved on the open end of the glove. The inner wall of the slot ring seat near the open end of the glove is provided with a second magnetic piece B. The insert ring seat and the slot ring seat are engaged with each other, and the second magnetic piece A and the second magnetic piece B attract each other.

[0010] More preferably, the filtration mechanism includes a sealing screw cap, which is screwed to the top opening of the passageway. A filter box is provided at the bottom end of the passageway and is located at the top opening of the backpack. The filter box has a first filter layer and a second filter layer arranged sequentially from top to bottom inside.

[0011] More preferably, the ventilation mechanism includes a suction fan, which is screwed to the middle of the bottom wall of the upper ventilation plate. The upper ventilation plate is located on the inner wall of the backpack directly below the filter mechanism, and the inner wall of the backpack directly below the suction fan is provided with a lower ventilation plate.

[0012] More preferably, the heat dissipation mechanism includes an exhaust pipe A, the top end of which is inserted into the middle of the bottom of the backpack, and the other end of the exhaust pipe A is connected to an air pump A. The other end of the air pump A is connected to two branch pipes, which respectively pass through the inner wall of the interlayer of the sleeves on both sides. An exhaust pipe B is inserted into the back of the backpack, and the other end of the exhaust pipe B is connected to an air pump B. The other end of the air pump B is connected to an air supply pipe, and the other end of the air supply pipe is connected to the back of the headgear.

[0013] More preferably, sealing rings are provided at the joints between the backpack and the exhaust pipe A, the air distribution pipe and the sleeve, the backpack and the exhaust pipe B, and the air supply pipe and the headgear.

[0014] More preferably, the fabric of the headgear, bodysuit, sleeves and bodysuit bottoms is divided into three layers, from the outside to the inside: a nano-protective layer, a self-healing layer and a hydrophobic and breathable layer.

[0015] This invention provides an airtight polymer membrane chemical protective suit, which has the following beneficial effects: The airtight polymer membrane chemical protective suit has a magnetically attached connection between the hood and the coverall, as well as between the gloves and the sleeves, through first sealing element A and first sealing element B, and second sealing element A and second sealing element B, respectively. This allows the components to be attracted and connected together, and at the same time, the first sealing layer and the second sealing layer fill the gaps at the connection, thereby ensuring that the components are sealed and effectively preventing toxic gases, liquids or particles from seeping in from the connection.

[0016] This airtight polymer membrane chemical protective suit has a filtration mechanism at the top of the backpack containing two filter layers. The first filter layer can filter large particulate impurities in the air, and the second filter layer can adsorb and remove toxic gases, thereby providing clean air for the user and ensuring respiratory safety.

[0017] This airtight polymer membrane chemical protective suit features a ventilation system with a suction fan that draws purified air into the backpack, while a heat dissipation system uses an air pump to divert air from the backpack into the sleeve lining and hood, effectively reducing the temperature of the arms, hands, and head, improving wearing comfort, and preventing stuffiness.

[0018] This airtight polymer membrane chemical protective suit features a three-layer fabric design. The outer nano-protective layer has a dense structure that blocks the penetration of liquid chemicals, dust, and radioactive particles, and its high-strength fibers resist scratches, extending the suit's lifespan. The middle self-healing layer contains microcapsule materials. When tiny cracks appear in the nano-protective layer, the microcapsules rupture and release a repair agent, which solidifies and fills the cracks through body temperature and movement, quickly completing a seal and automatically repairing damage to prevent contaminants from seeping in. The inner hydrophobic and breathable layer has micropores with a diameter smaller than toxic gas molecules but larger than water vapor molecules, allowing for one-way ventilation. This allows sweat and breathable moisture to escape into the gaps and then be discharged through the ventilation system, keeping the skin dry and preventing mold growth.

[0019] This airtight polymer membrane chemical protective suit, with its sealing rings at the joints of each component and the slightly positive pressure maintained by the ventilation mechanism inside the suit, combined with multi-layered fabric and sealing structure, can prevent the infiltration of toxic gases in all directions, further enhancing the airtightness and safety of the chemical protective suit. At the same time, the components can be quickly connected through magnetic and snap-fit ​​structures, making it easy to operate and enabling quick donning, doffing, and individual maintenance.

[0030] In this embodiment, as Figure 6 As shown, the filter mechanism 12 includes a sealing screw cap 1201, which is screwed to the top opening of the passage 1202. The bottom end of the passage 1202 is provided with a filter box 1203, which is located at the top opening of the backpack 11. The filter box 1203 is provided with a first filter layer 1204 and a second filter layer 1205 from top to bottom inside the filter box 1203.

[0031] In this embodiment, as Figure 6 As shown, the ventilation mechanism 13 includes a suction fan 1301, which is screwed to the middle of the bottom wall of the upper ventilation plate 1302. The upper ventilation plate 1302 is located on the inner wall of the backpack 11 directly below the filter mechanism 12. The inner wall of the backpack 11 directly below the suction fan 1301 is provided with a lower ventilation plate 1303.

[0032] In this embodiment, as Figure 6 As shown, the heat dissipation mechanism 14 includes an exhaust pipe A1401. The top end of the exhaust pipe A1401 is inserted into the middle of the bottom of the backpack 11. The other end of the exhaust pipe A1401 is connected to an air pump A1402. The other end of the air pump A1402 is connected to two branch pipes 1403. The two branch pipes 1403 pass through the inner wall of the interlayer of the sleeves 5 on both sides. An exhaust pipe B1404 is inserted into the back of the backpack 11. The other end of the exhaust pipe B1404 is connected to an air pump B1405. The other end of the air pump B1405 is connected to an air supply pipe 1406. The other end of the air supply pipe 1406 is inserted into the back of the headgear 1.

[0033] In this embodiment, as Figure 6 As shown, sealing rings are provided at the joints of backpack 11 with exhaust pipe A1401, air distribution pipe 1403 with sleeve 5, backpack 11 with exhaust pipe B1404, and air supply pipe 1406 with headgear 1.

[0034] In this embodiment, as Figure 7 As shown, the headgear 1, bodysuit 4, sleeves 5, and bodysuit bottoms 9 are made of three layers of fabric, from the outside to the inside: a nano-protective layer, a self-healing layer, and a hydrophobic and breathable layer.

[0035] The working process of this airtight polymer membrane chemical protective suit is as follows: like Figures 1 to 7As shown, firstly, the user can put on the main body of the entire protective suit, including the jumpsuit 4, sleeves 5, jumpsuit trousers 9, and jumpsuit boots 10. Then, the user aligns the first insert 201 of the first sealing member A2 at the bottom of the hood 1 with the first slot 301 of the first sealing member B3 at the top of the jumpsuit 4, and vertically inserts the first insert 201 into the first slot 301, so that the two are completely engaged. At this time, the first magnetic piece A203 and the first magnetic piece B302 will automatically adhere to each other due to magnetism, and the first sealing layer 202 will tightly fill the gap at the connection between the first insert 201 and the first slot 301, thereby ensuring the fit between the hood 1 and the jumpsuit 4. After sealing the connection, align the slot ring seat 701 of the second sealing member B7 at the opening end of the glove 8 with the insert ring seat 601, and press and engage it in the circumferential direction until the second magnetic piece A603 and the second magnetic piece B702 are attracted and fixed. At the same time, the second sealing layer 602 can tightly fill the gap at the connection between the slot ring seat 701 and the insert ring seat 601, thereby completing the sealing connection between the glove 8 and the sleeve 5. At this time, the user can fix the backpack 11 to the back of the onesie 4 through the back buckle, and tighten the sealing screw cap 1201 at the top opening of the backpack 11 so that it is threadedly connected to the top of the passage 1202. Then, normal work can be carried out.

[0036] During use, the user can activate the suction fan 1301 of the ventilation mechanism 13 according to the ambient temperature requirements. Simultaneously, the user can unscrew the sealing cap 1201, allowing outside air to be drawn into the filter box 1203 through the vent 1202. The air passes through the first filter layer 1204 to remove large particles, and then through the second filter layer 1205 to adsorb and remove toxic gases. The purified air, driven by the suction fan 1301, continues downwards through the upper and lower vents 1302 and into the backpack 11. At this time, the user can simultaneously activate the suction pumps A1402 and B1405. During this process, suction pump A1402... The backpack 11 is equipped with an interlocking exhaust pipe A1401 to draw in air and distribute it to two separate exhaust pipes 1403. The air is then transported through the exhaust pipes 1403 to the inner walls of the sleeves 5 on both sides and slowly discharged from the pipe openings, thereby reducing the temperature of the arms and hands. Meanwhile, the air pump B1405 draws in cool air from inside the backpack 11 through the exhaust pipe B1404 and pushes it through the air supply pipe 1406 to the back of the hood 1, allowing cool air to enter the hood 1 and cool the head. During this process, a sealing ring is installed at the connection between the pipe and the heat dissipation mechanism 14 to ensure that there is no air leakage during the air supply process, thereby ensuring the safety of the air breathed by the user and maintaining a slight positive pressure inside the garment to prevent toxic gases from seeping in.

[0037] During operations, when the outer layer of the chemical protective suit comes into contact with liquid chemicals, dust, or radioactive particles, the dense structure of its nano-protective layer can directly prevent these substances from penetrating to the inner layer. If it comes into contact with sharp objects, the high-strength fibers of the nano-protective layer can resist scratches, thus reducing the probability of surface damage and extending the overall service life. If the nano-protective layer develops microcracks due to external force, the microcapsule material within its internal self-healing layer will rupture, simultaneously releasing a repair agent to fill the crack. The repair agent is then solidified by the user's body temperature and movement, completing a resealing process within five minutes to prevent contaminants from seeping in. Furthermore, the user does not need to actively operate the self-healing process; the self-healing process occurs automatically after damage. It automatically starts after birth. During this time, the built-in sensor in the headgear 1 can receive fabric status prompts to confirm safety without interrupting the operation. The sweat and breath moisture generated by the user during operation can be automatically discharged to the gap between the self-healing layer and the hydrophobic breathable layer through the microporous structure of the hydrophobic breathable layer. Then, the moisture is discharged through the micropores of the cuff of the sleeve 5 by the internal ventilation mechanism 13, ensuring that the skin surface is dry and avoiding stuffiness and mold growth. At the same time, the micropore diameter of the hydrophobic breathable layer is smaller than the external toxic gas molecules but larger than the water vapor molecules, which can achieve one-way ventilation, thereby allowing internal moisture to be discharged while blocking the infiltration of external gases. In conjunction with the internal ventilation mechanism 13, the airtightness can be further enhanced.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
