Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of military clothing, and particularly relates to a rainwater backflow prevention military raincoat and a use method thereof. BACKGROUND

[0002] Although the existing military raincoat can shield rainwater to a certain extent, it has many obvious defects. First, the weight is generally heavy, which undoubtedly increases the load of officers and soldiers during action, and affects the flexibility and efficiency of combat or training. For example, in long-distance marching or rapid penetration tasks, the over-heavy raincoat will make the officers and soldiers feel tired faster.

[0003] Secondly, the wearing process is relatively complicated. In an emergency, such as sudden rain, the complex wearing steps may cause delay in battle. The common wearing method of raincoat needs officers and soldiers to spend a certain amount of time on arranging and buckling, which cannot meet the needs of rapid action of the army.

[0004] Thirdly, and most importantly, the existing military raincoat usually adopts a whole design, and during the action of officers and soldiers, rainwater is easy to drip along the lower edge of the raincoat body to the trousers and shoes. This not only makes the trousers and shoes of officers and soldiers wet, greatly affecting the comfort of action, but also may cause health problems such as frostbite and athlete's foot, and even affect the combat effectiveness and task execution ability of the army in serious cases. For example, during long-term field training or execution of covert tasks, wet shoes and socks will cause skin abrasion and infection of the feet, and then affect the action ability of soldiers. Therefore, it is urgent to develop a military raincoat that can effectively solve the above problems. SUMMARY

[0005] The purpose of the embodiment of the application is to provide a rainwater backflow prevention military raincoat and a use method thereof. The purpose is to solve the problem that the existing military raincoat is easy to cause rainwater to wet the lower leg and backflow into the shoe during combat or training in rainy days.

[0006] To achieve the above purpose, the following technical solutions are adopted in the application:

[0007] In a first aspect, a rainwater backflow prevention military raincoat is provided, which comprises a raincoat body.

[0008] The lower edge of the raincoat body is provided with an air inflation water blocking structure.

[0009] The air inflation water blocking structure comprises a closed cavity and at least one air inflation valve.

[0010] The air inflation valve is used for inflating the closed cavity.

[0011] The inflatable water-blocking structure expands outward to form a ring-shaped water-blocking eave after being inflated, and the outer edge of the inflatable water-blocking structure has a projected width greater than the width of the lower hem of the raincoat body.

[0012] In a possible implementation, the inflatable water-blocking structure is detachably installed on the lower hem of the raincoat body through a split connecting piece.

[0013] The split connecting piece is one of a zipper, a button group, or a magic tape.

[0014] In a possible implementation, the inflation valve is a one-way blow nozzle valve, which supports inflation of the sealed cavity by blowing through the mouth.

[0015] In a possible implementation, a miniature air pump is further included.

[0016] The miniature air pump is connected to the sealed cavity through a hose.

[0017] The miniature air pump is installed on the chest or the side waist of the raincoat and is configured with a manual press-type inflation switch.

[0018] In a possible implementation, the hose is embedded in the inner layer of the seam of the raincoat body.

[0019] In a possible implementation, the top of the inflatable water-blocking structure has an expansion length less than the expansion length of the bottom of the inflatable water-blocking structure.

[0020] In a possible implementation, the inflatable water-blocking structure includes at least three groups of air chambers.

[0021] The adjacent air chambers are connected.

[0022] In a possible implementation, the inflatable water-blocking structure is internally provided with a deformable support framework.

[0023] The support framework is composed of elastic metal wires that can be magnetically attracted to each other at both ends, and the energized support framework is unfolded from a folded state to a ring-shaped support structure.

[0024] In a possible implementation, the support framework is battery-powered, and the battery is any one of a lithium battery, a nickel-hydrogen battery, or a solid-state battery.

[0025] In a second aspect, a use method of the military raincoat is provided, based on the military raincoat of the first aspect, including the following steps:

[0026] The wearing step: the folded raincoat is taken out from the tactical vest interlayer, and the wearing is quickly completed through the split connecting piece.

[0027] The inflatable water-blocking step: according to the actual rainfall condition, the inflatable water-blocking structure is inflated to form a ring-shaped water-blocking eave.

[0028] Storage step: after use, release the gas in the closed cavity, fold the raincoat and store it in the tactical vest interlayer.

[0029] Compared with the prior art, the present application has the following beneficial effects:

[0030] The raincoat provided by the present application solves the problem of rainwater backflow at the lower hem of the raincoat body. The automatic inflation design does not require additional operation by the soldier, and can quickly take effect after wearing. It ensures the dryness of the lower leg and combat boots during rainy weather operations, and does not affect the flexibility of the structure due to its complexity. Compared with the existing raincoat body, this structure can significantly reduce the discomfort caused by wet trousers and shoes, reduce the risk of health problems such as frostbite and athlete's foot, and improve the concentration and sustained combat capability during rainy weather operations or training, fully meeting the dual requirements of protection and practicality of military equipment.

[0031] In one possible implementation, the split connection design gives the raincoat body greater adaptability and maintainability. When the raincoat body does not need the anti-backflow function in non-rainy days or tasks, the inflatable water-blocking structure can be quickly removed to reduce the weight of the raincoat body and improve the convenience of movement. When the inflatable water-blocking structure is worn, leaked, or has other problems, the component can be replaced individually without discarding the entire raincoat body, reducing equipment maintenance costs. At the same time, the magic tape and zipper connection methods are simple to operate and meet the needs of the army to respond quickly, ensuring that soldiers can efficiently install or remove the structure in emergency situations, balancing the practicality and economy of the equipment.

[0032] In one possible implementation, the one-way blow nozzle valve design fully considers the complex environment of field operations by the army. Without relying on external inflation equipment, rapid inflation can be achieved by blowing through the mouth, solving the inflation problem when there is a lack of power sources, air pumps, and other tools. This design is convenient to operate, and even in harsh weather or stressful tasks, soldiers can quickly complete the inflation operation to ensure that the inflatable water-blocking structure is effective in time, avoiding the influence of rainwater backflow on movement and improving the reliability of the equipment in emergency scenarios.

[0033] In one possible implementation, the design of the miniature compression pump provides a stable and efficient inflation method for the inflatable water-blocking structure. Compared with mouth blowing, it is more hygienic, faster, and more uniform in pressure, allowing the inflatable water-blocking structure to maintain a more stable expansion state. The pump body is installed on the chest or both sides of the body, allowing the soldier to operate with one hand without affecting tactical actions such as holding a gun or climbing, ensuring that the inflation state of the inflatable water-blocking structure can be adjusted at any time during the execution of the task, further improving the comfort and safety of rainy weather operations, and meeting the strict requirements of the army for the convenience of equipment operation.

[0034] In one possible implementation, the design of the hose embedded in the joint inner layer effectively avoids a series of problems that may be caused by the exposure of the hose. On the one hand, it prevents the hose from being hooked by branches, equipment, etc., causing damage or falling off, ensuring the continuity and stability of the inflation passage; on the other hand, it keeps the surface of the raincoat body flat, does not affect folding and storage, and does not cause discomfort due to the protruding hose rubbing the skin of the soldier. At the same time, this design enhances the overall aesthetics and structural integrity of the raincoat body, meeting the high standards of details and reliability required by military equipment.

[0035] In one possible implementation, the design of multiple groups of air chambers greatly improves the reliability and fault tolerance of the inflatable water-blocking structure. In complex field environments, partial damage to equipment is inevitable, but this design ensures that partial damage will not cause the overall protection function to fail, and still provides some water-blocking protection for the soldier. At the same time, the 35% width increment further expands the water-blocking range, reduces the probability of rainwater contacting the lower leg and shoes due to the fluctuation of the lower hem caused by the soldier's movements, significantly improves the protection effect in rainy weather, and reduces the adverse effects of the environment on combat training.

[0036] In one possible implementation, the support framework with magnetic poles that attract each other solves the problem of deformation of a simple inflatable structure under intense action, ensuring that the inflatable water-blocking structure always maintains a stable outwardly expanding shape and continuously effectively blocks rainwater. The switch control mode is easy to operate, and the soldier can flexibly switch the framework state according to the intensity of the action and the size of the rain, improving the stability and adaptability of the protection. This design enables the raincoat body to maintain good anti-inversion effect in various complex action scenarios, further ensuring the efficiency of the soldier's combat training.

[0037] A method for using a military raincoat, which fully considers the intense rhythm of the army's combat training, emphasizes speed and efficiency at every link from wearing to inflation to storage, greatly shortens the equipment operation time, and enables the soldier to devote more energy to task execution. The selection of different inflation modes adapts to different rain scenarios, ensuring effective protection in various weather conditions, while the simple and easy-to-understand operation process reduces the soldier's usage threshold, enabling them to operate skillfully even in complex environments, improving the practical value of the equipment and the rain combat capability of the army.

[0052] The technical solutions in the embodiments of the present application will be described clearly and completely in the present application, and obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0053] As shown in Figure 1 and Figure 2 The raincoat of the present application can include a raincoat body 100, and the lower edge of the raincoat body 100 is provided with an inflatable water blocking structure 200.

[0054] The inflatable water blocking structure 200 includes a closed cavity and at least one inflatable valve 201, and the closed cavity is shown.

[0055] The inflatable valve 201 is used to inflate the closed cavity.

[0056] The inflatable water-blocking structure 200 expands outward after being inflated to form a ring-shaped water-blocking eave, and the outer edge projection width of the inflatable water-blocking structure 200 is greater than the hem width of the raincoat body 100.

[0057] Optionally, the raincoat body 100 is made of 0.3mm thick ultralight PU-coated nylon composite material with a waterproof finish. The raincoat body 100 is designed as a split structure, including a detachable hood and cuff tightening devices.

[0058] The inflatable water-blocking structure 200 can be made of high-elasticity TPU material, featuring a ring-shaped hollow structure with an outer diameter of 3.2cm and a wall thickness of 1.8mm, and is sewn and fixed along the hem of the raincoat body 100. The interior forms a continuous, sealed cavity with a cross-sectional area of ​​2.5cm². 2 .

[0059] The inflation valve 201 can be a military-grade one-way inflation valve 201, with the valve body made of ABS plastic and an internal silicone sealing gasket, with a pressure resistance of ≥0.1MPa. The valve body protrudes 1cm from the surface of the raincoat body for easy operation.

[0060] Optionally, the interior of the inflatable water-blocking structure 200 can also be filled with a material with deformation recovery properties, such as a resilient sponge, as the base filling material.

[0061] When the inflation valve 201 is opened, air enters the interior of the inflatable water-blocking structure 200, filling it with air and causing the structure to expand outward to form a ring-shaped water-blocking eave. To release air, the structure can be squeezed to expel the air.

[0062] When in use, the inflatable water-blocking structure 200 expands outward to form a 5.5cm wide annular water-blocking eave, with the eave tilted downward at a 15° angle to effectively guide rainwater. During soldier marching, running, and other movements, the expanded hem can effectively catch rainwater flowing down the surface of the raincoat body 100 and guide it away from the calves and combat boots, preventing rainwater from dripping directly down the hem.

[0063] In this embodiment, by constructing an inflatable water-blocking structure 200 at the hem of the raincoat body 100, the problem of rainwater backflow at the hem of traditional military raincoats 100 is fundamentally solved. The automatic inflation design requires no additional operation from soldiers and takes effect quickly after being put on, ensuring the dryness of the calves and combat boots during rainy weather operations without affecting the flexibility of movement due to structural complexity. Compared with existing raincoat bodies 100, this structure can significantly reduce the discomfort caused by damp trousers and socks, reduce the risk of health problems such as frostbite and athlete's foot, and improve the focus and continuous combat capability during rainy combat or training, fully meeting the dual needs of military equipment for protection and practicality.

[0064] In one possible embodiment, such as Figure 3 As shown, the inflatable water-blocking structure 200 can be detachably installed on the hem of the raincoat body 100 via a split connector, which is one of a zipper 301, a button group 302, or a Velcro 303.

[0065] Optionally, the inflatable water-repellent structure 200 can be connected to the hem of the raincoat body 100 via Velcro 303. At least one hook-and-loop Velcro 303 can also be sewn onto the edge of the hem of the raincoat body 100, and a loop Velcro 303 can be sewn onto the corresponding position on the inside of the inflatable water-repellent structure 200. After being attached, it can be firmly fixed, and it can be separated by simply tearing it gently along the edge.

[0066] In addition, the inflatable water-blocking structure 200 can also be connected to the raincoat body 100 by a zipper 301. The zipper 301 is arranged along the hem edge, and its length is adapted to the hem. After being zipped up, it has good sealing performance and is easy to disassemble and install quickly.

[0067] In this embodiment, the split-connection design gives the raincoat body 100 greater adaptability and maintainability. In non-rainy weather or when the anti-backflow function is not required for the mission, the inflatable water-retaining structure 200 can be quickly disassembled, reducing the weight of the raincoat body 100 and improving ease of movement. When the inflatable water-retaining structure 200 experiences wear or leakage, this component can be replaced individually without discarding the entire raincoat body 100, reducing equipment maintenance costs. Meanwhile, the Velcro 303, zipper 301, and other connection methods are simple to operate, meeting the needs of rapid response in the military, ensuring that soldiers can efficiently install or disassemble the structure in emergency situations, balancing the practicality and economy of the equipment.

[0068] In one possible embodiment, the inflation valve 201 is a one-way mouthpiece valve, which supports the inflation of a sealed cavity by blowing air through the mouth, thus meeting the need for rapid inflation in emergency situations.

[0069] The inflation valve 201 uses a one-way nozzle valve, located on the inner side of the hem of the raincoat body 100 near the waist. The nozzle is foldable and can be fitted to the surface of the raincoat body 100 when not in use to avoid snagging. In an emergency, a soldier can easily open the nozzle with one hand and blow air 4-6 times through their mouth to inflate the inflatable water-blocking structure 200 to 90% fullness, meeting basic water-blocking requirements. The one-way valve design effectively prevents gas leakage, ensuring the structure remains in an expanded state.

[0070] In this embodiment, the one-way blow valve design fully considers the complex environment of field operations. It eliminates the need for external inflation equipment, allowing for rapid inflation simply by blowing air into the mouth, thus solving the inflation problem when power, air pumps, or other tools are unavailable. This design is easy to operate; even in inclement weather or during stressful missions, soldiers can quickly complete the inflation process, ensuring the timely effectiveness of the inflation-resistant water-blocking structure 200, preventing rainwater backflow from affecting operations, and improving the reliability of equipment in emergency scenarios.

[0071] In one possible embodiment, such as Figure 4 As shown, the raincoat also includes a miniature air pump 400, which is connected to the sealed cavity via a hose 401. The miniature air pump 400 is mounted on the chest or side of the raincoat body 100 and is equipped with a manual press-type inflation switch 402 for easy one-handed inflation.

[0072] Specifically, the raincoat body 100 is equipped with a miniature compressor pump on the chest. The pump body is made of lightweight materials, weighing ≤40g, and is compact in size, so it does not affect the soldier's tactical movements. The miniature compressor pump is connected to the inflatable water-blocking structure 200 via a hose 401. The pump body is equipped with a manual press-type inflation switch 402. A soldier can press it 3-6 times with one hand to fully inflate the inflatable water-blocking structure 200, expanding it outward by 4cm. During the pressing process, air continuously enters the inflatable water-blocking structure 200 through the hose 401. After releasing the switch, it automatically resets, and the operation is smooth and without jamming.

[0073] In this embodiment, the miniature compressor pump provides a stable and efficient inflation method for the inflatable water-blocking structure 200. Compared to oral blowing, it is more hygienic, and the inflation speed is faster and the pressure is more uniform, enabling the inflatable water-blocking structure 200 to maintain a more stable expansion state. The pump body is installed on the chest or both sides of the body, making it easy for soldiers to operate with one hand without affecting tactical movements such as holding a gun or climbing. This ensures that the inflation state of the inflatable water-blocking structure 200 can be adjusted at any time during missions, further improving the comfort and safety of operations in rainy weather, and meeting the strict requirements of the military for ease of equipment operation during combat.

[0074] In another possible embodiment, a negative pressure pack is also included, which is installed on the chest or sides of the raincoat body 100 at a convenient location for pressing.

[0075] The air inlet and outlet of the negative pressure pack are respectively connected to one-way valves, and the one-way valve of the air outlet of the negative pressure pack is used to connect with the hose 401.

[0076] The one-way valve located at the air inlet only allows air to enter. When the air in the negative pressure chamber is emptied, the negative pressure chamber is affected by pressure, and air will automatically enter the negative pressure chamber through the air inlet.

[0077] Meanwhile, the one-way valve located at the air outlet only releases air. By pressing the negative pressure bag, the air in the negative pressure bag is discharged into the hose 401 until the inflatable water-blocking structure 200 is fully inflated.

[0078] Optionally, the negative pressure chamber may also be equipped with a pressure relief valve for relieving pressure on the chamber. The negative pressure chamber is not shown.

[0079] In one possible embodiment, the hose 401 is embedded in the inner layer of the seam of the raincoat body 100, and the outer surface has no protruding structure to avoid affecting tactical movements or snagging equipment.

[0080] Optionally, the hose 401 connecting the miniature compressor pump and the inflatable water-blocking structure 200 is embedded in the inner layer of the seam of the raincoat body 100. The hose 401 is made of flexible material, has a diameter of 0.4 cm, and runs in the same direction as the seam of the raincoat body 100, completely hidden inside the fabric with no protrusions on the surface. The connection points of the hose 401 with the pump body and the inflatable water-blocking structure 200 are sealed to ensure no water or air leakage.

[0081] In this embodiment, the design of embedding the hose 401 within the seam effectively avoids a series of problems that might arise from the hose 401 being exposed. On the one hand, it prevents the hose 401 from being damaged or detached due to snagging on branches, equipment, etc., ensuring the continuity and stability of the inflation path; on the other hand, it keeps the surface of the raincoat body 100 flat, does not affect folding and storage, and prevents discomfort caused by the hose 401 protruding and rubbing against the soldier's skin. At the same time, this design enhances the overall aesthetics and structural integrity of the raincoat body 100, meeting the high standards of detail and reliability required for military equipment.

[0082] In one possible embodiment, the top unfolded length of the inflatable water barrier structure 200 is less than the bottom unfolded length of the inflatable water barrier structure 200.

[0083] Optionally, the top unfolded length of the inflatable water-blocking structure 200 is less than the bottom unfolded length. For example, the top dimension of the inflatable water-blocking structure 200 is 5-12 cm smaller than the bottom dimension, so that the inflatable water-blocking structure 200 forms an umbrella-shaped structure with a small top and a large bottom after inflation, which can structurally guide rainwater and effectively prevent rainwater backflow.

[0084] In one possible embodiment, such as Figure 5 and Figure 6 As shown, the inflatable water-blocking structure 200 may include at least three sets of air chambers 202. Adjacent air chambers 202 are connected, and the inflatable water-blocking structure 200 forms a water-blocking eave after being inflated.

[0085] Specifically, the inflatable water-blocking structure 200 is divided into 3 groups of air chambers 202, and different air chambers 202 can be set according to the original structural distribution of the lower hem of the raincoat body 100. The length of each group of air chambers 202 is adapted to the corresponding part of the lower hem of the raincoat body 100.

[0086] Furthermore, a connecting valve can be provided between adjacent air chambers 202 to control the gas flow between them. After inflation, each set of air chambers 202 expands outward by 3-4cm, and the overall water-blocking width is wider than the original hem of the raincoat body 100. Even if one set of air chambers 202 leaks air, the other two sets of air chambers 202 can still maintain their water-blocking function after the corresponding connecting valve is closed, effectively preventing rainwater from flowing back in.

[0087] In this embodiment, the multi-chamber design 202 significantly improves the reliability and fault tolerance of the inflatable water-blocking structure 200. In complex field environments, equipment inevitably suffers localized damage, but this design ensures that localized damage does not lead to the failure of the overall protective function, still providing soldiers with a certain degree of water-blocking protection. Simultaneously, the increased water-blocking width further expands the water-blocking range, reducing the probability of rainwater contacting the calves and shoes due to the undulation of the hem caused by soldier movements, significantly improving the protective effect during rainy operations and reducing the adverse impact of the environment on combat training.

[0088] In another possible embodiment, such as Figure 7 and Figure 8 As shown, the inflatable water-blocking structure 200 has a built-in deformable support frame 500, which is composed of elastic metal wires 501 with magnetic attraction at both ends. When powered on, the support frame 500 unfolds from a folded state into a ring support structure, which enhances the stability of the water-blocking eaves.

[0089] Optionally, the inflatable water-repellent structure 200 includes a built-in deformable support frame 500 made of elastic iron wire with magnetic poles installed at both ends. A control switch is installed on the surface of the raincoat body 100. When the switch is turned on, the magnetic poles at both ends of the iron wire attract each other, forming a ring-shaped support structure, causing the inflatable water-repellent structure 200 to expand outward by 3cm and remain stable, making it less prone to deformation even during vigorous movement by soldiers. When the switch is turned off, the magnetic attraction disappears, the frame can be folded, and it does not affect the storage of the raincoat body 100.

[0090] In addition, the support frame 500 can be composed of two overlapping memory iron wires and a magnetic ring 501 at the end of the memory iron wire. The magnetic ring 501 can be sleeved on another memory iron wire. When energized, the two magnetic rings 501 attract each other and move closer together. The two memory iron wires unfold from the overlapping state into a ring support structure, which enhances the stability of the water barrier.

[0091] In this embodiment, the magnetically attracted support frame 500 solves the problem of easy deformation of a simple inflatable structure under violent movements, ensuring that the inflatable water-blocking structure 200 always maintains a stable outward expansion shape and continuously and effectively blocks rainwater. The switch control method is easy to operate, and soldiers can flexibly switch the frame state according to the intensity of the movement and the size of the rain, improving the stability and adaptability of the protection. This design enables the raincoat body 100 to maintain a good anti-backflow effect in various complex action scenarios, further ensuring the combat training efficiency of soldiers.

[0092] In one possible embodiment, the support frame 500 is battery powered, and the battery is any one of lithium battery, nickel-metal hydride battery or solid-state battery, with a trigger response time of ≤0.5 seconds to ensure rapid activation.

[0093] Optionally, the support frame 500 is powered by a battery that is flexible to install and remove and can move the support frame 500 with only a small amount of power.

[0094] In addition, the support frame 500 can be powered by a single soldier's tactical power supply, eliminating the need for soldiers to carry additional dedicated batteries, reducing the types and weight of equipment carried, and improving the convenience of operations.

[0095] In this embodiment, the low-power design ensures that the support frame 500 can work continuously and stably during long-term field operations or training, and will not fail due to insufficient power, thus guaranteeing the continuous protection capability of the inflatable water-blocking structure 200.

[0096] In one possible embodiment, a method of using a military raincoat is provided, based on the military raincoat of the first aspect, comprising the following steps:

[0097] Donning procedure: Take out the folded raincoat body 100 from the tactical vest compartment and quickly put it on using the quick connector.

[0098] Inflatable water barrier steps: Based on the actual rainfall conditions, select the appropriate inflatable water barrier structure and inflate it to form a ring-shaped water-blocking eave.

[0099] Storage steps: After use, release the gas in the sealed cavity, fold the raincoat body 100 degrees and store it in the tactical vest compartment.

[0100] Specifically, when donning the raincoat, soldiers take out the folded raincoat body 100 from the tactical vest's inner layer, unfold it, and secure it with Velcro 303 and quick zipper 301. The entire process takes only 3 seconds. Depending on the intensity of the rain, soldiers can choose to inflate it manually with a compressor pump, blow air into it, or open the support frame 500 to activate the inflatable water-blocking structure 200.

[0101] For manual inflation, press the pump 5 times during moderate rain. For oral inflation, blow air 3 times during light rain. For opening the support frame (500), turn on the switch during heavy rain.

[0102] After use, turn off the switch to fold the frame, press the exhaust valve to release the gas, and then put the raincoat body back into the tactical vest compartment following the folding steps. The whole process should take no more than 30 seconds.

[0103] In this embodiment, the method of use fully considers the intense pace of troop combat training. Every step, from donning and inflation to storage, emphasizes speed and efficiency, significantly reducing equipment operation time and allowing soldiers to focus more on mission execution. The selection of different inflation methods adapts to various rain scenarios, ensuring effective protection under all weather conditions. At the same time, the simple and easy-to-understand operating procedures lower the barrier to entry for soldiers, enabling them to operate the equipment proficiently even in complex environments, thus enhancing the equipment's combat value and the troops' ability to fight in rainy weather.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
