Description

Technical Field

[0001] The present application relates to the field of protection, and in particular to a protective suit. Background Art

[0002] Protective clothing is work clothing designed to protect the human body from physical, chemical, and biological hazards. Its primary applications include firefighting, industrial, military, and medical applications. In the medical field, medical protective clothing is used by medical personnel (such as doctors, nurses, and public health workers) and those entering specific medical and health areas (such as patients, hospital visitors, and those entering infected areas). Its primary function is to isolate pathogens, harmful ultrafine dust, acidic and alkaline solutions, and electromagnetic radiation, thereby protecting personnel and maintaining a clean environment.

[0003] The type of protective clothing is selected based on the needs of the working environment. When the working environment requirements are high, fully enclosed protective clothing is generally used, and the inhaled air and exhaled gas need to be filtered to ensure the safety of the workers themselves and the cleanliness of the environment. For example, after the workers put on the protective clothing in the designated area, they enter the work area to work. Usually, they need to walk for a while to enter the work area. After entering the work area and starting work, they need to turn on the filter device of the protective clothing. For example, when a doctor enters the operating room and performs surgery, he turns on the filter device of the protective clothing. However, existing protective clothing cannot conveniently control the switch of the filter device. Utility Model Content

[0029] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0030] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, the elements defined by the phrase "comprising..." do not exclude the presence of other identical elements in the process, method, article, or device comprising the elements.

[0031] Existing protective clothing comes in both disposable and reusable varieties. Disposable protective clothing offers poor protection and, in situations requiring a higher level of protection, is not only unable to meet these requirements but also carries a high cost. Reusable protective clothing can be disinfected and cleaned using a disinfection device before continued use. Existing protective clothing often features filters that activate upon donning, which can affect the wearer's breathing comfort. However, existing technologies do not allow for selective turning the filter on and off.

[0032] The embodiment of the present application provides a protective clothing that can turn on and off the filter device at a designated place or time, which is beneficial to the wearer's breathing sensation.

[0033] In order to solve the problems in the prior art, the embodiments of the present application provide a protective suit.

[0034] Figure 1 Shows a schematic structural diagram of protective clothing provided by some embodiments of the present application; Figure 2 Schematic diagram of the external structure of the protective mask 310 provided in some embodiments of the present application is shown; Figure 3 A schematic diagram of the internal structure of the protective mask 310 provided in some embodiments of the present application is shown.

[0035] like Figures 1 to 3As shown, an embodiment of the present application provides a protective suit, comprising: a suit body 300 and a protective mask 310, the suit body 300 is used to be mounted on the surface of the human body to form a protective space, the suit body 300 is provided with a facial notch area 301, and the suit body 300 is provided with a switch button; the protective mask 310 is installed in the facial notch area 301 and is connected to the suit body 300, the protective mask 310 comprises a mask body 100 with a breathing port 101, a filter component 200 and a switch component 400, the filter component 200 is connected to the breathing port 101, and is used to filter the inhaled and discharged gas, the switch component 400 is provided between the filter component 200 and the breathing port 101, and is electrically connected to the switch button, and is used to control the connectivity between the filter component 200 and the breathing port 101.

[0036] Specifically, the garment body 300 is designed to be placed on the surface of the human body to form a protective space. The garment body 300 covers the head, torso, and feet of the human body, while the hands are exposed outside the garment body 300. The hands can be protected by wearing gloves, etc. The garment body 300 has a closing structure at the wrist to make the protective space as closed as possible. The garment body 300 is provided with a switch button, which can be an electrical button or a mechanical button. The switch button can be installed at any position on the garment body 300. However, to facilitate pressing by the wearer, the switch button is installed in a position that is easily accessible to the wearer's hand, such as the front of the garment body 300. The protective mask 310 is installed in the facial notch area 301 and is connected to the garment body 300, so that the internal space of the protective mask 310 is connected to the protective space formed by the garment body 300 and is sealed. The protective mask 310 and the garment body 300 can be integrally formed, fixedly connected, or detachably connected.

[0037] The protective mask 310 includes a mask body 100 having a breathing port 101. The position of the breathing port 101 is opposite to the position of the human mouth and nose, and can transport air through the breathing port 101 over the shortest distance and take away exhaled gas. The mask body 100 is also provided with a light-transmitting area 102. The light-transmitting area 102 is generally made of transparent glass or plastic. The light-transmitting area 102 is opposite to the position of the human eyes, making it convenient for the wearer to observe the external environment through the light-transmitting area 102. The filter component 200 is connected to the breathing port 101 and is used to filter the inhaled and exhaled gas. That is to say, when the filter component 200 is turned on, the filter component 200 filters the air entering the breathing port 101 during the wearer's inhalation to ensure the wearer's safety. When the wearer exhales, the filter component 200 filters the air exhaled from the breathing port 101 to ensure the cleanliness of the external environment.

[0038] The switch assembly 400 is disposed between the filter assembly 200 and the respiratory port 101 and is electrically connected to the switch button to control the connection between the filter assembly 200 and the respiratory port 101. That is, the switch button is used to control the on / off state of the switch assembly 400, which controls the connection between the filter assembly 200 and the respiratory port 101. For example, when the switch assembly 400 is in the on state, the filter assembly 200 is connected to the respiratory port 101, thereby filtering the gas inhaled and exhaled by the wearer. When the switch assembly 400 is in the off state, the filter assembly 200 is blocked from the respiratory port 101, and the gas exhaled and inhaled by the wearer does not pass through the filter assembly 200. The gas exhaled and inhaled by the wearer can be directly connected to the air outside the protective suit through other structures or directly.

[0039] Among them, the switch button and the switch component 400 can be communicatively connected or electrically connected, and the switch state of the switch component 400 can be switched by pressing the switch button multiple times, or multiple switch buttons can be set on the clothing body 300, and the multiple switch buttons are all electrically connected to the switch component 400 for respectively controlling the switching of the switch state of the switch component 400.

[0040] Continue to refer Figure 1 In some optional embodiments of the present application, the clothing body 300 includes a lower body part 320, an upper body part 330 and a head cover part 340 arranged in sequence, the facial notch area 301 is formed in the head cover part 340, and the switch button is arranged on the side of the upper body part 330 away from the head cover part 340, and is placed on the same side of the clothing body 300 as the facial notch area 301.

[0041] The switch button is located on the same side of the garment body 300 as the facial cutout area 301, making it easier for the wearer to identify its location and control its status. The switch button is located on the side of the upper body portion 330 away from the head cover portion 340, facilitating aseptic operation. In a medical environment, the wearer's hands must be in a clean area, and the wearer can control the switch button by elbowing. Therefore, placing the switch button near the wearer's waist makes it easier for the wearer to independently control the switch button and achieve aseptic operation.

[0042] Furthermore, in an optional embodiment of the present application, the switch button includes an on button 302 and an off button 303, and the on button 302 and the off button 303 are respectively placed on both sides of the center line of the clothing body 300, and the on button 302 and the off button 303 are both connected to the switch assembly 400 through wires, and the wires are laid on the inner surface of the clothing body 300.

[0043] The switch buttons include an on button 302 and an off button 303, which enable separate control of the different states of the switch assembly 400, preventing misoperation. For example, when the switch assembly 400 is in the off state, pressing the on button 302 switches the switch assembly 400 from the off state to the on state. Pressing the off button 303 again switches the switch assembly 400 from the on state to the off state. The on button 302 and the off button 303 are positioned on either side of the midline of the garment body 300. For example, the on button is closer to the left hand, and the off button 303 is closer to the right hand. This allows the wearer to control different switch buttons using different elbows, preventing misoperation. Both the on button 302 and the off button 303 are connected to the switch assembly 400 via wires, which are routed to the inner surface of the garment body 300. This wired connection ensures a more reliable connection and prevents signal degradation in unusual environments, which could affect the control of the switch assembly 400.

[0044] Continue to refer Figure 2 In a specific embodiment of the present application, the filter assembly 200 includes a main filter mechanism 210 and an auxiliary filter mechanism 220, and the switch assembly 400 includes a first switch valve group 410 and a second switch valve group 420. The first switch valve group 410 is arranged between the main filter mechanism 210 and the breathing port 101, and the second switch valve group 420 is arranged between the auxiliary filter mechanism 220 and the breathing port 101. The first switch valve group 410 and the second switch valve group 420 are both electrically connected to the switch button, and the switch states are opposite.

[0045] The switch valves in the first switch valve group 410 and the second switch valve group 420 may be solenoid valves, electric ball valves, electric stop valves, etc.

[0046] Specifically, the filter assembly 200 includes a primary filter mechanism 210 and an auxiliary filter mechanism 220. The primary filter mechanism 210 and the auxiliary filter mechanism 220 are independently connected to the breathing port 101. The on-off state between the breathing port 101 and the primary filter mechanism 210 and the auxiliary filter mechanism 220 is controlled by a first on-off valve assembly 410 and a second on-off valve assembly 420. The primary filter mechanism 210 and the auxiliary filter mechanism 220 are selectively operated by the first on-off valve assembly 410 and the second on-off valve assembly 420. For example, in the initial state, the on-off valve of the first on-off valve assembly 410 is closed, and the on-off valve of the second on-off valve assembly 420 is open, connecting the breathing port 101 to the auxiliary filter mechanism 220. When the wearer presses the on button 302 of the switch button, the on-off valve of the first switch valve group 410 opens, the on-off valve of the second switch valve group 420 closes, and the breathing port 101 is connected to the main filtering mechanism 210; when the wearer presses the off button 303 of the switch button, the on-off valve of the first switch valve group 410 closes, the on-off valve of the second switch valve group 420 opens, and the breathing port 101 is connected to the auxiliary filtering mechanism 220.

[0047] For example, the auxiliary filter mechanism 220 has a lower filtration level, and the wearer's breathing is smoother. The main filter mechanism 210 has a higher filtration level, and the wearer's breathing is less smooth. In a high-protection environment, the wearer is filtered through the main filter mechanism 210 to ensure personal safety.

[0048] Alternatively, the auxiliary filter mechanism 220 is a physical filter, which is more stable but has a lower filtration level. The main filter mechanism 210 is an ionization filter, which is more susceptible to environmental influences and is relatively unstable, but has a higher filtration level and can filter out tiny harmful substances that physical filtration cannot. In the event of a malfunction in the main filter mechanism 210, to prevent harmful substances in the main filter mechanism 210 from entering the breathing port 101 and to ensure smooth breathing, the first and second switch valve groups 410, 420 can be controlled by a switch button to connect the auxiliary filter mechanism 220 to the breathing port 101.

[0049] In an optional embodiment of the present application, the main filtering mechanism 210 includes a fine filtering device, and the auxiliary filtering mechanism 220 includes a coarse filtering device. The filtering device is selected based on the use environment to perform filtering.

[0050] In addition, continue to refer to Figure 1 In some embodiments of the present application, the filter assembly 200 also includes a connecting mechanism 230, which includes a first channel group 232, a second channel group 236 and a box body 231 with an inner cavity. The main filter mechanism 210 is connected to the box body 231 through the channel of the first channel group 232, and the auxiliary filter mechanism 220 is connected to the box body 231 through the channel of the second channel group 236. The switch valve of the first switch valve group 410 is arranged in the channel of the first channel group 232, and the switch valve of the second switch valve group 420 is arranged in the channel of the second channel group 236. The inner cavity of the box body 231 is connected to the breathing port 101.

[0051] The main filter mechanism 210 and the auxiliary filter mechanism 220 are connected to the breathing port 101 via a connecting mechanism 230, improving the stability and convenience of the structural connection. The inner cavity of the housing 231 is connected to the breathing port 101. The housing 231 is connected to the main filter mechanism 210 via the channels of the first channel group 232. A first on-off valve group 410 is disposed within the channels, used to block and open the channels, thereby connecting the inner cavity of the housing 231 to the main filter mechanism 210. The housing 231 is connected to the auxiliary filter mechanism 220 via the channels of the second channel group 236. A second on-off valve group 420 is disposed within the channels, used to block and open the channels, thereby connecting the inner cavity of the housing 231 to the auxiliary filter mechanism 220.

[0052] Figure 4 A partial cross-sectional view of a protective mask 310 provided in some embodiments of the present application is shown.

[0053] like Figure 4 As shown, in an optional embodiment of the present application, the box body 231 includes a first chamber 201 and a second chamber 202 isolated from each other, and the first chamber 201 and the second chamber 202 are both connected to the breathing port 101, the main filtering mechanism 210 includes a first air inlet filter 203 and a first air outlet filter 204, the auxiliary filtering mechanism 220 includes a second air inlet filter 205 and a second air outlet filter 206, the first channel group 232 includes a first air inlet channel 211 and a first air outlet channel 212, and the second channel group 236 includes a second air inlet channel 213 and a second air outlet channel 214; the first air inlet filter 203 is connected to the first chamber 201 through the first air inlet channel 211, the second air inlet filter 205 is connected to the first chamber 201 through the second air inlet channel 213, the first air outlet filter 204 is connected to the second chamber 202 through the first air outlet channel 212, and the second air outlet filter 206 is connected to the second chamber 202 through the second air outlet channel 214.

[0054] The box body 231 includes a first chamber 201 and a second chamber 202, which are isolated from each other. The openings of the first and second chambers 201, 202 face the respiratory port 101. The respiratory port 101 is arranged in a strip shape, with a portion of the respiratory port 101 facing the first chamber 201 and another portion of the respiratory port 101 facing the second chamber 202. In other words, the box body 231 completely covers the respiratory port 101. The first and second chambers 201, 202 separate the first and second air inlet filters 203, 205 for inlet filtration from the first and second air outlet filters 204, 206 for outlet filtration. The first and second air inlet filters 203, 204 of the main filtering mechanism 210 are placed on either side of the box body 231 and are fixedly connected to the opposite sides of the mask body 100. The first air inlet filter 203 is connected to the first chamber 201 via the first air inlet channel 211. One on-off valve of the first on-off valve assembly 410 is located within the first air inlet channel 211. The on-off valve is controlled by a switch button to open and close, thereby controlling the flow and blockage of the first air inlet channel 211. The first air outlet filter 204 is connected to the second chamber 202 via the first air outlet channel 212. Another on-off valve of the first on-off valve assembly 410 is located within the first air outlet channel 212. The on-off valve is controlled by a switch button to open and close, thereby controlling the flow and blockage of the first air outlet channel 212. The on-off valves of the first on-off valve assembly 410 within the first air inlet channel 211 and the first air outlet channel 212 operate synchronously, i.e., they open and close simultaneously.

[0055] The second air inlet filter 205 and second air outlet filter 206 of the auxiliary filter mechanism 220 are placed on either side of the housing 231 and fixedly connected to either side of the mask body 100. The second air inlet filter 205 and second air outlet filter 206 are respectively placed below the first air inlet filter 203 and first air outlet filter 204. The second air inlet filter 205 is connected to the first chamber 201 via the second air inlet channel 213. One on-off valve of the second on-off valve assembly 420 is placed in the second air inlet channel 213. The on-off valve is controlled by a switch button, thereby controlling the flow and blockage of the second air inlet channel 213. The second air outlet filter 206 is connected to the second chamber 202 via the second air outlet channel 214. Another on-off valve of the second on-off valve assembly 420 is placed in the second air outlet channel 214. The on-off valve is controlled by a switch button, thereby controlling the flow and blockage of the second air outlet channel 214. The on-off valves of the second on-off valve group 420 in the second air inlet channel 213 and the second air outlet channel 214 operate synchronously, that is, they are opened and closed at the same time.

[0056] In addition, continue to refer to Figure 4 In another specific embodiment of the present application, a first one-way valve 240 is respectively provided between the box body 231 and the first air inlet channel 211 and the second air inlet channel 213, and a second one-way valve 246 is respectively provided between the box body 231 and the first air outlet channel 212 and the second air outlet channel 214. The protective mask 310 includes an inhalation working state and an exhalation working state; in the inhalation working state, the first one-way valve 240 is opened and the second one-way valve 246 is closed; in the exhalation working state, the second one-way valve 246 is opened and the first one-way valve 240 is closed.

[0057] For example, a first inlet 244 and a second inlet 244 are defined on one side of the box body 231, and a first outlet 245 and a second outlet 245 are defined on the opposite side of the box body 231. A first one-way valve 240 is disposed in each of the first inlet 244 and the second inlet 244, and a second one-way valve 246 is disposed in each of the first outlet 245 and the second outlet 245. The first inlet 244 communicates with the first air inlet channel 211, the second inlet 244 communicates with the second air inlet channel 213, the first outlet 245 communicates with the first air outlet channel 212, and the second outlet 245 communicates with the second air outlet channel 214.

[0058] Taking the main filter mechanism 210 in operation as an example, during the inhalation operation, the first one-way valve 240 is open and the second one-way valve 246 is closed. Air is filtered by the first air inlet filter 203, then enters the first chamber 201 through the first air inlet channel 211 and enters the human body through the respiratory port 101. Because the second one-way valve 246 is closed, the first air outlet filter 204 is sealed from the second chamber 202. This prevents the wearer from re-inhaling the air in the first air outlet channel 212 during inhalation, and also prevents the wearer from re-inhaling toxic substances in the first air outlet filter 204. During the exhalation operation, the second one-way valve 246 is open and the first one-way valve 240 is closed. Air passes through the first air outlet channel 212 to the first air outlet filter 204, is filtered by the first air outlet filter 204, and is discharged outside the protective suit. Since the first one-way valve 240 is closed, the first air intake filter 203 and the first chamber 201 are blocked, thereby preventing the exhaled air from being discharged from the first air intake filter 203 .

[0059] Figure 5 Schematic diagrams of the structure of the first one-way valve 240 provided in some embodiments of the present application are shown, wherein the housing 241 of the first one-way valve 240 is partially cut away for convenience in illustrating the internal structure of the first one-way valve 240; Figure 6 A cross-sectional view of the first one-way valve 240 provided in some embodiments of the present application is shown.

[0060] like Figure 5 and Figure 6 As shown, in a specific embodiment of the present application, the first one-way valve 240 includes a shell 241, a valve core 242 and an elastic member 243. The shell 241 includes an inlet 244 and an outlet 245. One end of the valve core 242 is used to block the inlet 244. There is a gap between the circumference of the valve core 242 and the shell 241. The elastic member 243 is arranged between the outlet 245 and the valve core 242 to provide pressure to the valve core 242 to block the inlet 244. The outlet 245 is connected to the first chamber 201.

[0061] The first one-way valve 240 and the second one-way valve 246 have the same structure, with the first inlet 244 and the first outlet 245 positioned in opposite directions. The outlet 245 of the first one-way valve 240 communicates with the first chamber 201, while the inlet 244 of the first one-way valve 240 communicates with the first air inlet passage 211. During inhalation operation, the pressure within the first chamber 201 is lower than the pressure in the first air inlet passage 211. The valve core 242 compresses the elastic member 243, moving it toward the first chamber 201. The inlet 244 is opened, and the first air inlet passage 211 communicates with the first chamber 201. Gas enters the first air inlet filter 203 from the outside and enters the respiratory port 101 from the first air inlet passage 211.

[0062] The outlet of the second one-way valve 246 communicates with the first outlet channel 212, while the inlet of the second one-way valve 246 communicates with the second chamber 202. During exhalation, the pressure within the second chamber 202 exceeds the pressure in the first outlet channel 212. The valve core of the second one-way valve 246 compresses the elastic member toward the first outlet channel 212, opening the inlet and connecting the first outlet channel 212 with the second chamber 202. Gas enters the first outlet filter element 204 from the first inlet channel 211, is filtered, and then exits the protective suit. The operating process of the auxiliary filter mechanism 220 is similar and will not be further described here.

[0063] Figure 7 A schematic structural diagram of a first extension tube 251 and a second extension tube 250 provided in some embodiments of the present application is shown, wherein the directions of the first extension tube 251 and the second extension tube 250 shown in the figure are arbitrary directions.

[0064] In addition, if Figure 7 As shown, in an optional embodiment of the present application, the filter assembly 200 also includes a first extension tube 251 and a second extension tube 250, and the first extension tube 251 and the second extension tube 250 are arranged along the length direction of the mask body 100, the first extension tube 251 is connected to the air inlet of the first air inlet filter 203, and the second extension tube 250 is connected to the air outlet of the first air outlet filter 204; wherein, the opening of the first extension tube 251 is placed at the upper part of the first air inlet filter 203 along the length direction of the mask body 100, and the opening of the second extension tube 250 is placed at the lower part of the first air outlet filter 204 along the length direction of the mask body 100.

[0065] In other words, the first and second extension tubes 251 and 250 extend the air intake and exhaust of the first air inlet filter 203 and the second air outlet filter 206. Placing the first air inlet extension tube 251 at the top allows for fresher air. For example, in a dusty work environment, larger dust particles settle in the lower portion of the space, leaving the air in the upper portion cleaner. Placing the second air outlet extension tube 250 at the bottom prevents contamination of the fresh air in the upper portion.

[0066] Of course, in other embodiments of the present application, the first extension tube 251 is rotatably connected to the first air inlet filter 203, and the second extension tube is rotatably connected to the first air outlet filter 204, so as to realize the position adjustment of the first extension tube 251 and the second extension tube 250 in different application scenarios. For example, the first extension tube 251 and the second extension tube 250 are both facing the rear of the human body, avoiding the exhaled warm gas from being sprayed toward the patient during medical treatment.

[0067] The above description is only a specific embodiment of the present application. Those skilled in the art will clearly understand that for the convenience and brevity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the scope of protection of the present application.
