DETAILED DESCRIPTION

[0023] To more clearly illustrate the technical solutions of this application, the following briefly describes the drawings used in the description of the embodiments. Obviously, the drawings described below are merely examples or embodiments of this specification. Those skilled in the art can apply this specification to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0024] As shown in this specification and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not specifically refer to the singular and may also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements. The term "based on" means "at least partially based on". The term "some embodiments" means "at least one embodiment"; the term "other embodiments" means "at least one other embodiment". The relevant definitions of other terms will be given in the following description.

[0025] Since the placement or use position of the products in this manual can be changed at will, the directional words such as "up", "down", "left", "right", "front", and "back" mentioned in this manual only indicate relative position relationships and are not used to limit absolute position relationships.

[0026] The industrial manufacturing process has high requirements for the cleanliness of the working environment, and it is necessary to strictly control the pollution of the clean environment of the work area by the operators themselves. In addition, in the industrial manufacturing process, it is not only necessary to prevent the operators from polluting the work area, but also to prevent the influence of dust, bacteria, viruses and other substances on the workers themselves. In some solutions, the wearer usually wears protective clothing for protection. When wearing protective clothing, the wearer can observe the outside through the lenses fixed on the protective helmet. However, when the wearer is nearsighted, since the lenses of the protective clothing are fixed to the helmet, the convexity of the lenses cannot be adjusted according to the wearer's vision, and the needs of wearers with different vision cannot be met. As a result, the wearer cannot clearly and accurately observe the outside when wearing protective clothing, which reduces the wearing experience and practicality of the dust-proof clothing.

[0027] This specification provides a protective suit 100, Figure 1 is a schematic diagram of a simple module of protective clothing according to some embodiments of this specification; Figure 2 It is a schematic diagram of the structure of protective clothing shown in some embodiments of this specification.

[0028] Combine Figure 1-Figure 2As shown, the protective suit 100 may include a protective suit body 10 and a protective helmet 20. The protective helmet 20 is connected to the protective suit body 10. The protective helmet 20 is provided with a lens frame 21. The lens frame 21 includes a lens slot 22 for placing one or more lenses 23. The one or more lenses 23 are detachably arranged in the lens slot 22. The detachable lens 23 design allows the wearer to increase or decrease the number of lenses 23 or replace the lenses 23 before putting on the protective suit 100, thereby adjusting the convexity of the lenses 23. This makes it more convenient for the wearer to observe the outside through the lenses 23 while wearing the protective suit 100, meeting the needs of wearers with different degrees of myopia.

[0029] The protective clothing body 10 refers to the part of the protective clothing 100 that accommodates the wearer's body except the head. In some embodiments, the protective clothing body 10 may include a protective coat 11 and protective trousers 12 connected to the protective coat. Among them, the protective coat 11 may include a chest portion 111, a sleeve portion 112 and a neck portion 113, and the neck portion 113 is connected to the protective helmet 20. The protective trousers 12 may include a trouser leg portion 121 and a shoe body portion 122 connected to the trouser leg portion 121. The chest portion 111 is integrally connected to the trouser leg portion 121, and the chest portion 111 and the trouser leg portion 121 are both provided with a zipper (not shown in the figure). Before wearing the protective clothing 100, the wearer can open the zippers of the chest portion 111 and the trouser leg portion 121, and then put the lower body, upper body and head into the trousers, coat and protective helmet 20 in sequence, and finally zip up to complete the wearing.

[0030] In some embodiments, the lens 23 may include an integral lens or a split lens. An integral lens means that the same lens 23 corresponds to both the wearer's left eye (or glasses worn on the left eye) and right eye (or glasses worn on the right eye). In some embodiments, when the lens 23 is an integral lens, the wearer can adjust the convexity of the integral lens according to their vision. For example, before putting on the protective suit 100, the wearer installs a lens 23 of corresponding convexity in the lens groove 22, or increases or decreases the number of lenses 23. In some embodiments, when the lens 23 is a split lens, the wearer can adjust the number and convexity of the lenses 23 corresponding to the left and right eyes respectively according to their vision. For example, if the wearer's left eye has a different degree of myopia than the right eye, the number of lenses 23 or the convexity of the lenses 23 can be adjusted according to the degree of myopia of the left and right eyes respectively, so that the left and right eyes can see more clearly through the lenses 23. For the sake of convenience, unless otherwise specified, some embodiments of this specification will be described using split lenses as an example.

[0031] In addition, it should be noted that the types of lenses can include plano lenses and convex lenses. Since plano lenses have little effect on the wearer's observation, the lenses described in the embodiments of this specification mainly refer to convex lenses. Plano lenses can be used to seal the protective helmet. For example, the protective suit 100 may include plano lenses (not shown in the figure) and a plano lens frame (not shown in the figure) that connects the plano lenses to the protective helmet 20. The plano lens frame is arranged around the side of the plano lenses and is sealed with the plano lenses. That is, the plano lenses, the plano lens frame and the protective helmet 20 can form a seal, and the plano lenses isolate the inside and outside of the protective helmet 20.

[0032] In some embodiments, combined Figure 2-Figure 5 As shown, the lens groove 22 may include a first sub-lens groove 221 and a second sub-lens groove 222 that are spaced apart, and one or more lenses 23 may include at least one first sub-lens 231 and at least one second sub-lens 232. At least one first sub-lens 231 is detachably disposed in the first sub-lens groove 221. At least one second sub-lens 232 is detachably disposed in the second sub-lens groove 222. The first sub-lens 231 in the first sub-lens groove 221 and the second sub-lens 232 in the second sub-lens groove 222 may correspond to the left eye and the right eye of the wearer, respectively. In this embodiment, by providing independent first sub-lens grooves 221 and second sub-lens grooves 222, the convexity of the lens 23 can be adjusted according to the degree of myopia of the left and right eyes, respectively, so that the wearer can observe more clearly through the lens 23.

[0033] In some embodiments, the lens frame 21 may further include a distance adjustment device 24, which is used to adjust the distance between the first sub-lens groove 221 and the second sub-lens groove 222 in the spacing direction. The spacing direction of the first sub-lens groove 221 and the second sub-lens groove 222 corresponds to the spacing direction of the wearer's eyes. That is, the distance between the first sub-lens groove 221 and the second sub-lens groove 222 needs to correspond to the wearer's eye spacing. The spacing direction of the first sub-lens groove 221 and the second sub-lens groove 222 can be adjusted by Figure 3-Figure 5 Indicated by the arrow X in the middle. In some embodiments, when the wearer's eye distance is relatively wide, the distance between the first sub-lens groove 221 and the second sub-lens groove 222 can be increased by the distance adjustment device 24. Conversely, when the wearer's eye distance is relatively narrow, the distance between the first sub-lens groove 221 and the second sub-lens groove 222 can be reduced by the distance adjustment device 24. In this embodiment, the distance adjustment device 24 can be provided to adjust the distance between the lenses 23 corresponding to the left and right eyes, thereby adapting to wearers with different eye distances, allowing the wearer to observe the outside world in a more comfortable manner, and improving the wearing experience and practicality of the protective suit 100.

[0034] Figure 3 is a schematic structural diagram of the first movable plate and the second movable plate in a movable state according to some embodiments of this specification; Figure 4 This is a structural schematic diagram of the first movable plate and the second movable plate shown in some embodiments of this specification when they are in a relatively fixed state.

[0035] In some embodiments, combined Figure 1-Figure 4 As shown, the distance adjustment device 24 may include: a first fixing member 241, a locking member 242, a first movable plate 243, and a second movable plate 244. The first fixing member 241 is connected to the lens frame 21, and a slide groove 2411 is provided on the first fixing member 241. The first movable plate 243 is connected to the first sub-lens groove 221, and the second movable plate 244 is connected to the second sub-lens groove 222. The first movable plate 243 and the second movable plate 244 are spaced apart in the slide groove 2411 and can move along the length direction of the slide groove 2411. A plurality of positioning holes are provided on the first movable plate 243 and the second movable plate 244. When the locking member 242 passes through the positioning holes on the first movable plate 243 and the second movable plate 244 at the same time, the first movable plate 243 and the first movable plate 243 are relatively fixed, and at this time the distance between the first sub-lens 231 and the second sub-lens 232 is fixed. When the locking member 242 is disengaged from the positioning holes on the first movable plate 243 and the second movable plate 244 , the first movable plate 243 and the second movable plate 244 can move relative to each other, and the distance between the first sub-lens 231 and the second sub-lens 232 can be adjusted.

[0036] As an example only, the first fixing member 241 can be a fixed plate, and a slide groove 2411 is provided on the fixed plate. The first movable plate 243 and the second movable plate 244 are movably provided in the slide groove 2411. The first movable plate 243 and the second movable plate 244 are movably provided along the length direction of the fixed plate (such as Figure 3-Figure 4 A plurality of first positioning holes 2431 and a plurality of second positioning holes 2441 are respectively provided along the width direction of the fixing plate (as shown by the arrow X in the middle). Figure 3-Figure 4On the fixed plate (as shown by the arrow Y in the middle), the first movable plate 243 and the second movable plate 244 are spaced apart. The projections of the first movable plate 243 and the second movable plate 244 in the width direction of the fixed plate at least partially overlap. The first movable plate 243 is connected to the first sub-lens 231, which can drive the first sub-lens 231 to move along the length direction of the fixed plate during the movement of the first movable plate 243, thereby adjusting the position of the first sub-lens 231 in the length direction of the fixed plate. The second movable plate 244 is connected to the second sub-lens 232, which can drive the second sub-lens 232 to move along the length direction of the fixed plate during the movement of the second movable plate 244, thereby adjusting the position of the second sub-lens 232 in the length direction of the fixed plate. The locking member 242 may include a locking rod, a locking bolt, etc. The locking member 242 is arranged on the side of the first movable plate 243 away from the second movable plate 244. As shown Figure 3 As shown, when the locking member 242 does not simultaneously penetrate the first positioning hole 2431 and the second positioning hole 2441, the first movable plate 243 and the first movable plate 243 can move relative to each other, and the distance between the first sub-lens 231 and the second sub-lens 232 is in an adjustable state. Figure 4 As shown, when the locking member 242 passes through one of the first positioning holes 2431 of the first movable plate 243 and one of the second positioning holes 2441 of the second movable plate 244 at the same time, the first movable plate 243 and the second movable plate 244 are relatively fixed.

[0037] Before donning the protective suit 100, the wearer can adjust the distance between the first sub-lens 231 and the second sub-lens 232 along the length of the slide groove 2411 based on their own interocular distance to achieve better viewing. Specifically, the wearer can remove the locking member 242 from the first positioning hole 2431 and the second positioning hole 2441, then control the movement of the first movable plate 243 and the second movable plate 244 to adjust the distance between the first sub-lens groove 221 and the second sub-lens groove 222. After adjustment, the locking member 242 is inserted into the corresponding first positioning hole 2431 and the second positioning hole 2441 to secure the lens.

[0038] In some embodiments, the locking member 242 may be an elastic telescopic rod, one end of which may be connected to the fixed plate, and the other end of which may be telescopic along the width of the fixed plate. When the first positioning hole 2431 and the second positioning hole 2441 are aligned with the position of the elastic telescopic rod, the other end of the elastic telescopic rod can be inserted into the first positioning hole 2431 and the second positioning hole 2441 under the action of elastic force to lock the first movable plate 243 and the second movable plate 244. This eliminates the need for the wearer to manually insert the elastic telescopic rod into the first positioning hole 2431 and the second positioning hole 2441, effectively reducing the difficulty of operation for the wearer.

[0039] In some embodiments, the first movable plate 243 and the second movable plate 244 can be disposed in the same chute 2411. For example, an isolation block (not shown) is disposed between the first movable plate 243 and the second movable plate 244. The first movable plate 243 and the second movable plate 244 can move relative to the isolation block. The isolation block can ensure that the first movable plate 243 and the second movable plate 244 are separated by a certain distance to prevent collision between the first movable plate 243 and the second movable plate 244.

[0040] In other embodiments, the chute 2411 may include a first chute (not shown) and a second chute (not shown), the first chute and the second chute being spaced apart and arranged parallel to each other along the width direction of the fixed plate. The first movable plate 243 is movably disposed in the first chute, and the second movable plate 244 is movably disposed in the second chute. By disposing the first movable plate 243 and the second movable plate 244 in the first chute and the second chute, respectively, the movement paths of the first movable plate 243 and the second movable plate 244 can be restricted.

[0041] Figure 5 It is a structural schematic diagram of a distance adjustment device according to other embodiments of this specification.

[0042] In other embodiments, Figure 5 As shown, the distance adjustment device 24 may include: a second fixing member 245, a connecting screw 246, a first threaded sleeve 247 and a second threaded sleeve 248. The second fixing member 245 is connected to the lens frame (for example, Figure 1-Figure 2 The length direction of the connecting screw 246 (such as Figure 5 The second sub-lens groove 221 is provided on the first threaded sleeve 247 (for example, provided at one end of the first threaded sleeve 247 away from the connecting screw 246), and the first threaded sleeve 247 is sleeved on the connecting screw 246 and is threadedly connected to the first threaded end. The second sub-lens groove 222 is provided on the second threaded sleeve 248 (for example, provided at one end of the second threaded sleeve 248 away from the connecting screw 246), and the second threaded sleeve 248 is sleeved on the connecting screw 246 and is threadedly connected to the second threaded end. The rotation of the connecting screw 246 can be converted into the movement of the first threaded sleeve 247 and the first sub-lens groove 221 along the length direction of the second fixing member 245, and converted into the movement of the second threaded sleeve 248 and the second sub-lens groove 222 along the length direction of the second fixing member 245.

[0043] As an example only, the second fixing member 245 can be a fixed plate, on which a first base, a second base, and a third base are provided (the first base, the second base, and the third base are not shown in the figure), and the first base is used to support the connecting screw 246 on the fixed plate and enable the connecting screw 246 to be relative to the fixed plate. The second base is used to support the first threaded sleeve 247 on the fixed plate and enable the first threaded sleeve 247 to move along the length direction of the fixed plate. The third base is used to support the second threaded sleeve 248 on the fixed plate and enable the second threaded sleeve 248 to move along the length direction of the fixed plate. That is, the connecting screw 246 can only rotate along its own axial direction relative to the fixed plate, and the first threaded sleeve 247 and the second threaded sleeve 248 can only move horizontally along the length direction of the fixed plate and cannot rotate relative to the fixed plate. Before wearing the protective suit 100, the wearer can rotate the connecting screw 246 according to his or her own eye distance. Since the first threaded sleeve 247 and the second threaded sleeve 248 cannot rotate relative to the fixed plate, the rotation of the connecting screw 246 can be converted into the horizontal movement of the first threaded sleeve 247 and the second threaded sleeve 248 along the length direction of the fixed plate. The horizontal movement of the first threaded sleeve 247 and the second threaded sleeve 248 along the length direction of the fixed plate can respectively drive the first sub-lens groove 221 and the second sub-lens groove 222 to move, thereby adjusting the distance between the first sub-lens 231 and the second sub-lens 232.

[0044] In some embodiments, the distance adjustment device 24 can be disposed at the bottom or top of the lens groove 22. For example, the first threaded sleeve 247 and the second threaded sleeve 248 can be connected to the bottom of the first sub-lens groove 221 and the second sub-lens groove 222, respectively. For another example, the first threaded sleeve 247 and the second threaded sleeve 248 can be connected to the top of the first sub-lens groove 221 and the second sub-lens groove 222, respectively.

[0045] Figure 6 It is a schematic structural diagram of the first sub-lens groove according to some embodiments of this specification.

[0046] In some embodiments, combined Figures 1-6 As shown, the first sub-lens slot 221 may include multiple mounting slots 2211, each of which may be used to accommodate a first sub-lens 231. The wearer may place the first sub-lens 231 into or remove the first sub-lens 231 from the mounting slot 2211 as needed, thereby adjusting the overall convexity of the first sub-lens 231. In some embodiments, the second sub-lens slot 222 may be the same as or similar to the first sub-lens slot 221.

[0047] In some embodiments, combined Figure 1-Figure 2As shown, the protective suit 100 may further include a heat dissipation device, which may include an exhaust fan 25, an air inlet (not shown in the figure), and a plurality of exhaust ports (not shown in the figure) provided on the back of the protective suit main body 10 (for example, the back of the chest portion 111). As an example only, the exhaust fan 25 is connected to the outside of the back of the protective suit main body 10. The exhaust fan 25 may include a shell and a fan body (not shown in the figure) housed in the shell, and a gas pipeline (not shown in the figure) is provided between the inside of the shell and the protective suit 100. The air inlet may be provided on the shell of the exhaust fan 25 to connect the inside of the shell with the outside. One or more exhaust ports are provided on the back of the protective suit main body 10 to connect the outside of the protective suit 100 with the inside of the protective suit 100. When the exhaust fan 25 is working, the negative pressure formed by the exhaust fan 25 can introduce external air into the inside of the protective suit 100 via the air inlet and the gas pipeline, and the gas inside the protective suit 100 can be discharged from the protective suit 100 through the exhaust port.

[0048] In this embodiment, the exhaust fan 25 is provided to quickly exhaust the heat in the protective suit 100, thereby reducing the temperature inside the protective suit 100. Moreover, since the exhaust fan 25 is provided on the back of the protective suit 100, the wearer's flexibility when putting on the protective suit 100 can be reduced, making it easier for the wearer to perform corresponding work while wearing the protective suit 100. By providing the air inlet and exhaust port, air exchange can be achieved between the inside and outside of the protective suit 100, thereby improving heat dissipation efficiency and wearing comfort.

[0049] In some embodiments, the lens holder 21 can be positioned externally to the protective helmet 20, i.e., the lens holder 21 is positioned outside the plain lenses. Placing the lens holder 21 externally to the protective helmet 20 makes it easier for the wearer to adjust the lenses 23. In some embodiments, the lens holder 21 can be positioned internally to the protective helmet 20, i.e., the lens holder 21 is positioned inside the plain lenses. Placing the lens holder 21 internally to the protective helmet 20 effectively prevents contamination of the lens holder 21 from the external environment.

[0050] In some application scenarios, when the lens frame 21 is set inside the protective helmet 20, the moist air exhaled by the wearer may cause the lens 23 to be blurred, affecting the wearer's activities. In some embodiments, the heat dissipation device may also include an exhaust pipe (not shown in the figure), one end of the exhaust pipe is connected to at least one exhaust port of a plurality of exhaust ports, and the other end of the exhaust pipe is located around the lens frame 21. Among them, the other end of the exhaust pipe is located around the lens frame 21 means that the distance between the port of the exhaust pipe and any part of the lens frame 21 is less than a preset distance (the preset distance can be 5 cm, 3 cm, 1 cm, etc.). The gas exhaled by the wearer can be transported to the exhaust port via the exhaust pipe and discharged from the protective suit 100, thereby discharging moisture in the protective suit 100 and preventing the lens 23 from fogging.

[0051] In some embodiments, combined Figure 1-Figure 2 As shown, the protective suit 100 may further include a breathing valve 26, and the heat dissipation device may further include an air intake pipe (not shown in the figure), one end of the air intake pipe being connected to the air intake gas channel of the breathing valve, and the other end of the air intake pipe being located around the lens frame 21. The other end of the air intake pipe being located around the lens frame 21 means that the distance between the port of the air intake pipe and any part of the lens frame 21 is less than a preset distance (the preset distance may be 5 cm, 3 cm, 1 cm, etc.). The breathing valve 26 may be provided at a position corresponding to the wearer's face on the protective helmet 20, and the breathing valve 26 may be used to allow the wearer to breathe normally when wearing the protective suit 100. The breathing valve 26 is provided with a gas channel, which is used to supply air to the interior of the protective suit 100 for the wearer to breathe. The outlet of the gas channel of the breathing valve 26 may be connected to the air intake pipe, and the air discharged from the air intake pipe may be blown toward the lens 23 on the lens frame 21, sweeping away debris (e.g., dust) on the lens 23 and keeping the lens 23 clean.

[0052] In some embodiments, the air intake duct can be used in conjunction with the exhaust duct described in other embodiments of this specification. That is, the airflow delivered by the air intake duct can be used to clear debris from the lens 23, and the moisture in the protective suit 100 can be discharged through the exhaust duct to prevent the lens 23 from fogging and further keep the lens 23 clean.

[0053] In some embodiments, when the lens frame 21 is positioned on the side of the lens frame 21 located inside the protective suit 100, a non-slip member (e.g., a silicone strip) can be provided. This non-slip member can help the lens frame 21 fit the wearer's skin better. Similarly, a silicone strip can also be provided on the side of the breathing valve 26 located inside the protective suit 100.

[0054] In some embodiments, an elastic member may be provided between the exhaust fan 25 and the protective suit body 10 to provide a buffer, reduce the impact of the exhaust fan 25 on the protective suit body 10 and the wearer, and improve wearing comfort. Exemplary elastic members may include latex pads, sponge pads, silicone pads, springs, and the like.

[0055] In some embodiments, combined Figure 1-Figure 2 As shown, the back of the protective helmet 20 can be provided with a ventilation port 27, through which the humid air inside the protective suit 100 (e.g., the humid air concentrated in the protective helmet 20) can be discharged. This not only effectively alleviates the stuffiness inside the protective helmet 20, but also further reduces the probability of fogging of the lens 23. In addition, since the ventilation port 27 is also provided with a filter device (not shown in the figure), the filter device can filter out impurities (such as dust and other fine particles) in the air passing through the ventilation port 27, thereby preventing cross-contamination between the interior and exterior of the protective suit 100. Exemplary filter devices may include filter cotton, filter mesh, etc.

[0056] In some embodiments, the joints of the protective suit body 10 may be provided with elastic connection structures (not shown). As an example only, the elastic connection structures may include elastic fiber structures made of spandex. The elastic fiber structures may be provided at locations on the protective suit 100 corresponding to the wearer's elbows, shoulders, waist, knees, and other parts. Since the elastic fiber structures have good elastic properties, they can make the wearer more flexible when performing movements such as bending and squatting.

[0057] In some embodiments, the protective suit 100 may further include a buffer (not shown in the figure), which may be used to reduce the impact force generated when the wearer collides with an external object and protect the wearer. As an example only, the buffer may include a buffer sponge, which may be arranged inside the protective helmet 20. When the wearer wears the protective suit 100, the buffer sponge may separate the protective helmet 20 from the wearer's head to avoid direct contact between the protective helmet 20 and the wearer's head, thereby protecting the wearer's head. It will be understood that the above example is merely a specific example of the buffer in this specification and does not limit the type or setting method of the buffer. In some embodiments, the buffer may also include a silicone pad, a spring pad, etc. In some embodiments, the buffer may also be arranged at important joints of the protective suit 100 corresponding to the wearer, such as elbows, shoulders, etc.

[0058] In some embodiments, the protective suit 100 may also include elastic members (not shown) positioned at one or more locations, such as the cuffs, neck, ankles, or waist. These elastic members can be used to adjust the caliber of one or more of these locations, thereby making the protective suit 100 more comfortable for wearers of varying body types. By way of example only, elastic members may include Velcro, elastic bands, elastic band assemblies, elastic cords, and the like. Elastic bands are circular bands with a certain degree of elasticity that can be placed around the corresponding areas of the cuffs, neck, ankles, and waist of the protective suit 100. Because of their elasticity, they can be expanded and contracted based on the wearer's body type, thereby making the protective suit 100 more comfortable for wearers of varying body types. An elastic band assembly refers to a combination of an elastic band and an elastic buckle. For example, an elastic waistband may be positioned at the corresponding area of ​​the waist of the protective suit 100. Elastic bands may be placed around the corresponding areas of the cuffs, neck, ankles, and waist of the protective suit 100. The elastic band has multiple elastic openings along its length, and an elastic buckle is provided at one end of the elastic band. When the elastic buckle is engaged with different elastic openings, the inner diameter of the elastic band increases or decreases accordingly. Therefore, the wearer can adjust the elastic band to the appropriate inner diameter according to their needs, thereby making the protective suit 100 fit better.

[0059] In some embodiments, the elastic member can also be used in conjunction with the breathing valve 26 and / or lens frame 21 described in other embodiments of this specification. For example, the lens frame 21 can be provided with an elastic cord, which can be located outside or inside the protective helmet 20. The wearer can adjust the elastic cord based on their head size to make the lens frame 21 fit the face more closely. Furthermore, when adjusting the lens frame 21, a non-slip member (e.g., a silicone strip) is provided on one side of the lens frame 21 located inside the protective suit 100, further ensuring a consistent fit with the wearer's face.

[0060] The beneficial effects that may be brought about by the protective clothing in the embodiments of this specification include but are not limited to: (1) Through the detachable lens design, the wearer can increase or decrease the number of lenses 23 or replace the lenses 23 before wearing the protective clothing, so that the lenses are more suitable for the wearer's myopia level, making it more convenient for the wearer to observe the outside through the lenses while wearing the protective clothing, and meeting the needs of wearers with different myopia levels; (2) By setting a distance adjustment device, the distance between the lenses corresponding to the left and right eyes can be adjusted, thereby adapting to the eye distance of different wearers, allowing the wearer to observe the outside in a more comfortable way, improving the wearing experience and practicality of the protective clothing. (3) The heat in the protective suit can be quickly discharged by setting an exhaust fan, thereby reducing the temperature inside the protective suit; (4) The elastic fiber structure provided at the elbows, shoulders, waist, knees and other parts of the protective suit can make the wearer more flexible when bending over, squatting and other movements; (5) The impact force generated when the wearer collides with external objects can be reduced by providing a buffer, thereby protecting the wearer; (6) The caliber of one or more parts of the cuffs, neck, ankles and waist can be adjusted by providing elastic parts at one or more parts of the cuffs, neck, ankles and waist, thereby making the protective suit more suitable for wearers of different body shapes. It should be noted that different embodiments may produce different beneficial effects. In different embodiments, the beneficial effects that may be produced may be any one or a combination of the above, or any other possible beneficial effects.
