[0028] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] The embodiment of the present application provides a protective suit, which can solve the problem in the related art that when the protective suit is broken, it is impossible to find the damaged part of the protective suit and take relevant measures to reduce the risk of infection.

[0030] See also Figures 1 to 6 As shown, the present application provides a protective suit, which includes a protective suit body 1 and a color-changing piece 5, wherein the protective suit body 1 is a double-layer structure, specifically including an outer layer 2 and an inner layer 3, combined with Figure 3 As shown, an interlayer space 4 is formed between the outer layer 2 and the inner layer 3, and the color-changing element 5 is located in the interlayer space 4; specifically, the color-changing element 5 changes color when it encounters air. When the outer layer 2 is damaged, due to the existence of the inner layer 3, it can provide double-layer protection, that is, the virus is not easy to enter the protective clothing body 1 and come into contact with the human body. Generally, the protective clothing is white, and the color-changing element 5 mixes with the air to produce a color-changing reaction. The color-changing area can be captured by the naked eye and remedial measures can be taken, such as patching the damaged area with tape to block the gap in the outer layer 2.

[0031] The embodiment of the present application provides a protective suit. Since the original protective suit is divided into an outer layer 2 and an inner layer 3, it is equivalent to double-layer protection. At the same time, there is an interlayer space 4 between the inner layer 3 and the outer layer 2, and a color-changing part 5 is provided in the interlayer space 4. The color-changing part 5 will change color when it comes into contact with air. When the outer layer 2 of the protective suit is damaged, the outside air enters the interlayer space 4 and mixes with the color-changing part 5 therein, causing the color-changing part 5 to change color. We can find the damaged part of the outer layer 2 of the protective suit by observing which specific part of the protective suit changes color, so as to paste a supplementary layer on the damaged part to maintain the normal use of the protective suit. Therefore, it can solve the problem in the related art that when the protective suit is broken, it is impossible to find the damaged part of the protective suit and take relevant measures to reduce the risk of infection.

[0032] Specifically, the interlayer space 4 is filled with gas, and the gas filled therein is an inert gas that does not react with the color-changing element 5. Optionally, the inert gas is helium or argon, and the color-changing element 5 mainly changes color by chemically reacting with oxygen in the air.

[0033] In some optional embodiments, see Figure 3 As shown, there are multiple interlayer spaces 4. When one of the interlayer spaces 4 is damaged, since it is filled with inert gas, on the one hand, this interlayer space 4 will deflate. On the other hand, the color-changing part 5 in the interlayer space 4 will come into contact with the outside air, and then a color-changing reaction will occur, so that the damaged part can be quickly found, and the supplementary layer can be attached to the location of the interlayer space 4, which has the advantage of dividing the damage range.

[0034] In some optional embodiments, see Figure 3 As shown, a plurality of interlayer spaces 4 are connected in series via a one-way limiting member 6 , and at least one of the interlayer spaces 4 is provided with a sealing plug 7 .

[0035] Specifically, combined Figure 3 As shown, taking the torso of the protective suit body 1 as an example, a row of several interlayer spaces 4 arranged along the length direction of the torso is formed into a group, and multiple groups of interlayer spaces 4 are arranged along the circumferential direction of the torso:

[0036] In one embodiment, a sealing plug 7 is provided at least at one location of each interlayer space 4 to fill the interlayer space 4 with inert gas; and because the multiple interlayer spaces 4 are connected in series through a one-way limiter 6, the inert gas can only be transmitted along a specific route, i.e. Figure 3 In the embodiment shown, the seals are sequentially transferred to the interlayer spaces 4 along the path from bottom to top, so the sealing plug 7 should be set on the starting interlayer space 4, that is, Figure 3 and Figure 5 There are 7 sealing plugs shown.

[0037] Specifically, the sealing plug 7 is used to block the inlet 41 of the inert gas.

[0038] Specifically, the inert gas enters the adjacent interlayer spaces 4 in sequence through the one-way limiter 6, so that the interlayer spaces 4 are filled with gas and remain in a bulging state. Since the gas can only flow in one direction under the limitation of the one-way limiter 6, it will not be discharged from the inlet 41 at the starting end, nor will it flow back into the adjacent interlayer space 4. A sealing plug 7 is provided at the inlet 41 at the starting end for sealing.

[0039] Optionally, the one-way limiter 6 can use a one-way valve or a one-way valve, which is arranged between two adjacent interlayer spaces 4. Before the inert gas is filled and after the inert gas is filled, the one-way valve or the one-way valve blocks the adjacent interlayer spaces 4. When the inert gas is being filled and the one-way valve or the one-way valve is subjected to the pressure of the gas filling, the interlayer spaces 4 will be connected in series to be filled with the inert gas.

[0040] Taking the one-way valve as an example, the one-way limiter 6 is combined with Figure 3 and Figure 4 As shown, the one-way valve is made of rubber material and includes a first valve 61 and a second valve 62. A guide channel is formed at one end of the first valve 61 and the second valve 62, and the guide channel faces one side of the inlet 41. Optionally, the guide channel is trumpet-shaped;

[0041] Since the rubber material itself has the adhesion property, when not subjected to the pressure of gas filling, the first valve 61 and the second valve 62 adhere to each other so that each interlayer space 4 is independently closed and can prevent the gas that has passed through from flowing back. When the interlayer space 4 is inflated, the guide channel can also play the role of guiding the gas, that is, the guide channel is expanded under the inflation pressure so that the inert gas can enter the interlayer space 4.

[0042] Preferably, the inert gas in this embodiment is helium, which has a low density and can pass through the guide channel smoothly.

[0043] In some optional embodiments, see Figure 1 、 Figure 3 and Figure 4 As shown, the protective suit also includes a control device 8, specifically, the control device 8 includes a controller 82 and a pressure sensor 81, combined with Figure 1 As shown, the controller 82 is connected to the protective clothing body 1 , and the pressure sensor 81 is connected to the controller 82 . The pressure sensor 81 is arranged on the side of the one-way limiter 6 close to the outer layer 2 .

[0044] Specifically, combined Figure 4 As shown, when the interlayer space 4 is filled with inert gas, the outer layer 2 and the inner layer 3 are in a separated state, and the pressure sensor 81 is arranged on the side of the one-way limiter 6 close to the outer layer 2, and the outer layer 2 is not in contact with the pressure sensor 81; if the interlayer space 4 is damaged and the gas in the interlayer space 4 leaks out, the outer layer 2 will also deflate and come into contact with the pressure sensor 81. The pressure sensor 81 is subjected to pressure and transmits a signal to the controller 82. The user can detect that the protective clothing is damaged according to the changes in the controller 82 and take remedial measures in time.

[0045] Specifically, the control device 8 also includes an alarm 83, which is connected to the controller 82. When the controller 82 receives a signal from the pressure sensor 81, it will sound an alarm to attract the user's attention. The alarm 83 can be set Figure 1 The chest position shown can also be set at the wrist or arm position to facilitate the personnel in the protective suit to observe the damaged alarm.

[0046] Optionally, the alarm 83 includes a buzzer and / or a warning light. When the warning light turns on, it indicates that the protective suit is damaged. At the same time, the buzzer can also emit an alarm to prevent the user from not paying attention to the warning light in time. Alternatively, there can be only a buzzer without a warning light.

[0047] In some optional embodiments, see Figures 3 to 5 As shown, the color-changing member 5 is fixed on two adjacent one-way limit members 6. The color-changing member 5 includes a tube body 51 and a liquid-absorbing cotton 52. Specifically, the liquid-absorbing cotton 52 absorbs liquid that changes color when exposed to oxygen. The liquid-absorbing cotton 52 is located in the tube body 51, and a through hole 53 is opened on the side of the tube body 51 close to the outer layer 2:

[0048] When the outer layer 2 is damaged, air enters the interlayer space 4 from one side of the outer layer 2 and contacts the liquid absorbent cotton 52 through the through hole 53. The oxygen in the air reacts with the liquid in the liquid absorbent cotton 52, causing the liquid to change color. Optionally, the liquid in the liquid absorbent cotton 52 is a ferrous salt solution, which is green when not in contact with air and turns yellow after contact with oxygen in the air.

[0049] Of course, the color-changing member 5 can also be fixed on the inner layer 3 , and a through hole 53 is provided on the side of the tube body 51 facing the outer layer 2 .

[0050] Optionally, the through holes 53 are spaced and evenly arranged on the tube body 51 .

[0051] Optionally, a long hole is opened on one side of the tube body 51 close to the outer layer 2, exposing the absorbent cotton 52 to a large area. When the outer layer 2 is damaged, the outside air can contact the absorbent cotton 52 faster and over a larger area and produce a chemical reaction, allowing the user to find the damaged area more quickly.

[0052] Alternatively, the color-changing component 5 can also use color-changing silica gel. The color-changing silica gel has a strong adsorption effect on water vapor in the air. At the same time, it can display different colors by changing the amount of cobalt chloride crystal water contained in it, that is, it gradually changes from blue before moisture absorption to light red as the amount of moisture absorption increases, and can also clearly indicate the location of the damaged interlayer space 4; and the color-changing silica gel can be reused.

[0053] In some optional embodiments, the protective clothing preferably includes a fresh air system 9, see Figure 2As shown, the fresh air system 9 is connected to the protective suit body 1. Optionally, the fresh air system 9 is located at the back waist of the protective suit body 1, which can filter external dust and bacteria, automatically filter the air and send it into the protective suit to ensure the air quality inside the protective suit. At the same time, the filtration level of the fresh air system 9 is a filter mesh of H12 or above to ensure that the protective suit's protection efficiency against viruses is not lower than that of an N95 mask, and the positive pressure space it forms can maintain the human body in a more comfortable air pressure environment.

[0054] In some optional embodiments, the protective suit body 1 includes a head protective suit 11 and a torso protective suit 12. Specifically, the head protective suit 11 and the torso protective suit 12 are sewn together as one piece. An area for the face to be exposed is left on the head protective suit 11, and a transparent plastic cover is sewn on the edge of the area, so that the wearer does not need to wear goggles for eye protection, thereby reducing the wearing burden.

[0055] The front piece of the torso protective suit 12 is provided with a sealed zipper, which can be opened to facilitate the wearer to enter from here, and the sealed zipper is also provided with Velcro. The cuffs and trouser legs of the torso protective suit 12 are provided with rubber bands or elastic ropes: the wearer enters the protective suit from the sealed zipper, pulls up the sealed zipper and sticks the Velcro, and wears rubber gloves and protective boots on the wrists and ankles to ensure that the inside of the protective suit is in a relatively sealed environment.
