Description

Technical Field

[0001] The invention relates to the technical field of protective clothing, in particular to an anti-static protective clothing. Background Art

[0002] Anti-static protective clothing is a kind of clothing used to prevent the generation and accumulation of static electricity, especially for those who need to work in an anti-static environment, such as in the electronics industry, precision instrument manufacturing and other fields. This kind of clothing is usually made of anti-static materials, which can effectively avoid the generation and accumulation of static electricity, so as to reduce the potential harm caused by static electricity to the working environment and equipment.

[0003] Regarding the production and manufacturing of protective clothing, the Chinese invention patent with patent number CN113712300B discloses a new type of durable protective clothing with anti-static function, including lower garment, upper garment and head, with a magnetic suction mechanism arranged on the front of the head, the second elastic cord fixedly connected to the middle of the front of the head, the brim fixedly connected to the front of the head near the top, and the first magnetic block fixedly connected to the front of the brim. The invention makes the protective clothing have anti-static function and more durable by setting the bottom fabric of the upper garment, lower garment and head to be all-polyester fabric, the middle fabric to be pip55, and the outer fabric to be anti-static silk and polyester fiber.

[0004] The above scheme uses a specific fabric combination to form an anti-static protective clothing. Although it has an anti-static function to a certain extent, in actual use, because the above-mentioned goggles are fixed on the hat of the protective clothing, when the user actually wears it, the goggles cannot always be directly in front of the user's eyes, and cannot stably fit the user's eyes, which may cause problems such as obstructed vision, limited field of view or goggles slipping, reducing stability when wearing; at the same time, since the human body will generate static electricity due to friction with the inside of the protective clothing when working, the static electricity generated inside cannot be discharged, which may cause static electricity accumulation, endangering human health, reducing the service life of the protective clothing and work safety, and is not conducive to special environment operations. Summary of the invention

[0029] See also Figure 1 and Figure 2 , which is a schematic diagram of the overall appearance structure of an anti-static protective clothing of the present invention; the anti-static protective clothing of the present application enhances the stability of the goggles 110 when worn by adding a hoop 210 structure and a conductive fiber layer 140, and effectively guides and disperses static electricity, thereby improving the overall wearing comfort and safety of the protective clothing, solving the technical problems of the prior art that the protective clothing does not fit when worn, reduces wearing stability, cannot discharge internal static electricity, and reduces the service life and work safety of the protective clothing, and achieves the technical effects of fitting the eyes when worn, improving wearing stability, effectively discharging internal static electricity, and improving the service life and work safety of the protective clothing.

[0030] Embodiment 1: Figure 1-Figure 3 As shown, the present application discloses an anti-static protective clothing comprising a head 100, goggles 110, a top 120 and a bottom 130, wherein the side of the head 100 in contact with the human body is detachably connected with a fixing component for fixing the goggles 110 and conducting internal static electricity; The conductive fiber layer 140 is evenly distributed between the head 100, the upper garment 120 and the lower garment 130, and is used to quickly conduct internal static electricity to the outside; The fixing assembly includes a hoop 210, a fixing magnet 211, a wire 220 and a head iron sheet 230; The hoop 210 is an annular structure, and there are two of them connected to each other, which are respectively arranged on the top of the human head and the back of the head, and are used to provide a fixed position for the protective clothing head 100 and the goggles 110; The conductors 220 are provided in plurality and are evenly fixed on the inner side of the protective clothing and connected to the conductive fiber layer 140 for conducting internal static electricity; There are multiple fixed magnets 211, which are evenly arranged along the length direction of the hoop 210; a magnetic component corresponding to the fixed magnet 211 is arranged inside the head 100, which is used to fix the position of the protective clothing head 100 and the goggles 110 by cooperating with the fixed magnet 211 through magnetic attraction; The head iron sheet 230 is provided with a plurality of pieces, corresponding to the fixed magnets 211 located at the back of the head one by one; one end of the head iron sheet 230 is connected to the conductive fiber layer 140 through the wire 220, and the other end is connected to the corresponding fixed magnet 211 through magnetic attraction, which is used to fix the back of the head of the protective clothing 100 and cooperate with the fixed magnet 211, the wire 220 and the conductive fiber layer 140 to form a complete electrostatic conduction path to conduct internal static electricity together; Preferably, the hoop 210 is an adjustable structure, made of aminonitrile fiber, and has a diameter slightly larger than the circumference of the human head; the length of the hoop 210 can be adjusted by manually adjusting the buckle, so that the present application can be adjusted according to different human head sizes, expanding the scope of application and improving wearing comfort.

[0031] The fabrics of the head 100, top 120 and bottom 130 are all polyester fabrics, which are used to prevent static electricity on the outside of the protective clothing. The middle layer fabric grade is IP55, and the outer layer fabric is preferably anti-static silk and polyester fiber; the goggles 110 are used to protect the wearer's eyes from external damage, and are preferably made of polycarbonate material; all of them are prior art and will not be described here.

[0032] When the embodiment of the present application is actually in operation, the steps are as follows: first, the wearer puts on the top 120 and the bottom 130 of the protective suit neatly to ensure that all parts fit the body; then, the hoop 210 is fixed to the human head and the protective suit head 100 and the hoop 210 are attracted to each other through the fixed magnet 211 to achieve the wearing and fixing of the hoop 210 and the protective suit head; finally, the goggles 110 are adjusted to a suitable position and are magnetically fixed by the fixed magnet 211 on the hoop 210 at the top of the head to ensure that the external environment can be clearly observed. When the goggles 110 are in operation, the static electricity generated by the friction between the human hair and the protective suit can be conducted to the conductive fiber layer 140 inside the protective suit through the wire 220, and then the conductive fiber layer 140 disperses the static electricity, and finally released to the outside through the static electricity discharge point outside the protective suit.

[0033] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: The invention solves the technical problems in the prior art of not fitting well when worn, reducing wearing stability, failing to discharge internal static electricity, and reducing the service life and work safety of protective clothing, and achieves the technical effects of fitting well to the eyes when worn, improving wearing stability, effectively discharging internal static electricity, and improving the service life and work safety of protective clothing.

[0034] Embodiment 2: In order to reduce the friction between human hair and the inside of the protective clothing when wearing anti-static protective clothing for work, thereby reducing the generation of internal static electricity, the present application proposes the following technical solutions for the above technical problems, specifically: like Figure 2-Figure 3 As shown, the fixing assembly further includes a supporting portion for separating a human body from the protective clothing; The support part includes an air column 240 for separating the protective clothing head 100 from the human head; The air column 1 240 is provided in plurality, corresponding to the head iron sheet 230 one by one and sleeved on the outside of the corresponding wire 220; The air column 1 240 is a hollow cylindrical structure, one end of which is connected to the corresponding head iron sheet 230, and the other end is connected to the protective clothing head 100 at the corresponding position.

[0035] The material of the air column 240 is lightweight rubber or silicone material and its interior is connected to the air pump through a pipeline; it can play a buffering role during high-intensity operations, thereby improving the adaptability and wearing comfort of the protective clothing and reducing the pressure of the protective clothing on the head.

[0036] The air column 240 provided in the present application can effectively separate the protective clothing head 100 from the human head, thereby avoiding or reducing direct friction between the head and the inside of the protective clothing, and extending the service life of the protective clothing; since static electricity is usually generated by friction between different materials, this separation can significantly reduce static electricity generated by friction between human movements (such as turning the head, bending over, etc.) and the inside of the protective clothing.

[0037] Embodiment 3: When the human body is performing high-intensity work, due to high friction, parts of the human body will fit closely with the inside of the protective clothing. In order to improve the air permeability of the protective clothing and reduce the friction between the human body and the protective clothing, the present application proposes the following technical solutions for the above technical problems, specifically: like Figure 4 and Figure 5 As shown, the support portion further includes an isolation vest 150 and a second air column assembly 300; The isolation vest 150 is fixed in the protective clothing top 120 through the air column assembly 2 300 to reduce the friction between the front and back of the human body and the protective clothing; The air column assembly 2 300 is provided in multiple groups and is evenly fixed between the top 120 and the isolation vest 150 to support the protective clothing top 120.

[0038] Preferably, the interior of the isolation vest 150 is composed of metal conductive fibers and acrylic copper complex conductive fibers, which are used to conduct static electricity generated by body friction to the outside of the protective clothing through the isolation vest 150 and the air column component 2 300.

[0039] In the prior art, air blowing is usually used to expand the protective clothing to reduce the generation of internal friction static electricity. However, in situations where a high degree of protection is required, such as when working in a biosafety laboratory or a medical treatment site, the air blowing process may cause external dust and harmful substances to enter the protective clothing through the airflow, aggravating the diffusion and penetration of these substances, failing to achieve the protective effect, and even damaging human health.

[0040] The present application not only separates the human body from the protective clothing by setting up multiple air column components 2 300, but also realizes the support and ventilation of the protective clothing without introducing external airflow, thereby improving the wearing comfort and breathability, making the present application suitable for occasions with higher protection requirements and special protection, thereby enhancing the morphological stability and protective effect of the protective clothing, and avoiding the influence of external dust and harmful substances.

[0041] Embodiment 4: In order to expand the scope of application of the present application, make the present application applicable to wearers of different body shapes, and improve the flexibility of the present device, the present application proposes the following technical solutions for the above technical problems, specifically: like Figure 5-Figure 7 As shown, the gas column assembly 2 300 includes a connecting iron sheet 310 and a sleeve 340; There are two connecting iron sheets 310, one is fixed on the top 120, and the other is fixed on the isolation vest 150, which are used to connect the wire 220 and the conductive fiber layer 140 to form a conductive path; The sleeve 340 is sleeved on the outside of the wire 220 , and one end of the sleeve 340 is connected to the connecting iron sheet 310 on the top 120 , and the other end is connected to the connecting iron sheet 310 on the isolation vest 150 .

[0042] The sleeve 340 is an elastic telescopic structure and an annular airbag 350 is fixed on the outer side of the fixed end thereof to further provide sufficient support and protection for the protective clothing.

[0043] like Figure 6 As shown, the gas column assembly 2 300 further includes a spring 330 and a clamp 320; One end of the spring 330 is connected to the corresponding connecting iron sheet 310 on the protective clothing top 120, and the other end is connected to the corresponding wire 220, so as to provide elastic support; There are multiple clips 320 , all of which are detachably mounted on the outside of the telescopic section of the sleeve 340 to adjust the distance between the isolation vest 150 and the protective top 120 .

[0044] Preferably, in order to improve the clamping force of the clamp 320, as Figure 7As shown, the clip 320 is a U-shaped airbag structure and both ends thereof are provided with mutually cooperating fastening magnets 321, and the fastening magnets 321 are used to stably sleeve the clip 320 on the telescopic end of the sleeve 340. When multiple clips 320 are manually clamped on the outside of the telescopic section of the sleeve 340, due to the increase of multiple annular airbags 350, the telescopic section of the sleeve 340 is lengthened, so that the distance between the isolation vest 150 and the protective top 120 is expanded.

[0045] The present application can conveniently adjust the distance between the isolation vest 150 and the protective top 120 by arranging different numbers of clips 320 on the outside of the sleeve 340, so that the wearer can flexibly adjust the fit and support of the protective clothing according to personal needs or changes in the working environment, thereby improving the adaptability and comfort of the protective clothing; at the same time, by controlling the inflation amount of the annular airbag 350, it can further provide sufficient support and protection for the protective clothing, so that the protective effect of the device will not be affected by being too tight or loose.

[0046] The provision of the spring 330 and the wire 220 can provide additional elastic support for the protective suit, so that the sleeve 340 and the wire 220 in the protective suit can have a certain buffering and recovery ability when subjected to external force, thereby maintaining the stability of the protective suit and ensuring the stability of the shape of the protective suit during wearing.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
