Description

Technical Field

[0001] This invention relates to the field of oxygen supply equipment technology, specifically to a portable high-altitude emergency oxygen supply device based on solid-liquid reaction. Background Technology

[0002] Oxygen supply equipment is a device used to provide oxygen, mainly including oxygen cylinders, oxygen generators, oxygen compressors, oxygen pipelines, etc. Its function is to deliver oxygen to equipment or people that need oxygen support to meet the oxygen demand in production or daily life. Oxygen generating equipment is also a type of oxygen supply equipment. Oxygen is generally prepared by physical or chemical methods, through different reactions to produce and supply oxygen to meet people's oxygen supplementation needs. It is widely used in medical, industrial, mining, meteorological, aviation, diving, scientific research and other fields. In high-altitude environments, due to the thinness of oxygen, oxygen generating and supply equipment has also become one of the essential items for high-altitude tourism and work. Currently, oxygen supply and generation equipment used in high-altitude environments typically relies on bottled oxygen cylinders for timely oxygen replenishment during tourism and work. However, due to limited storage capacity, a large number of cylinders must be carried to ensure sufficient oxygen supply, significantly increasing the burden and impacting the user experience. Existing continuous oxygen generation devices are also inconvenient to carry and use in high-altitude environments due to limitations in size, power consumption, and environmental regulations. Therefore, a portable and quickly usable continuous oxygen supply device is lacking. This paper proposes a portable high-altitude emergency oxygen supply device based on solid-liquid reaction. This device is small in size, highly portable, and can quickly start generating and continuously supply oxygen when needed, meeting the requirements for prolonged oxygen replenishment and making it suitable for high-altitude activities. Summary of the Invention

[0003] To address the problems in existing technologies, this invention provides a portable high-altitude emergency oxygen supply device based on solid-liquid reaction. It has a small overall size and excellent portability. At the same time, it can quickly start to generate and continuously supply oxygen when needed, meeting the needs of long-term oxygen supplementation, and is suitable for use in high-altitude activities. The technical solution adopted by the present invention to solve its technical problem is a portable high-altitude emergency oxygen supply device based on solid-liquid reaction, including a mixing tank and a protective tank. The mixing tank has an arc-shaped guide groove on its side and a slider is slidably connected inside the arc-shaped guide groove. The top and bottom of the mixing tank are respectively provided with connecting pipe A and connecting pipe B. A fixed rod is vertically fixed at the bottom of the mixing tank, located on the side of the connecting pipe B, and a rotating ring A is movably connected to the bottom of the outer periphery of the fixed rod. A torsion spring is installed between the bottom of the fixed rod and the top of the rotating ring A. A connecting rod is horizontally fixed on the side of the rotating ring A and connected to the slider through the connecting rod. A clamping plate is symmetrically fixed on both sides of the bottom end of the fixed rod.

[0004] By adopting the above technical solution, the mixing tank is the main structure of this device, which is used to mix solid and liquid raw materials. The slider structure can slide inside the arc-shaped guide groove, and when it slides, it will drive the rotation of the clamping plate structure. The torsion spring is installed at the installation position of the rotating ring A to play a reset role. When the slider slides, the torsion spring will be compressed. After the slider is released, the torsion spring can drive the slider to automatically reset. The clamping plate structure is used to dock with the opening and closing end of the liquid storage tank.

[0005] Specifically, the bottom of the mixing tank is detachably connected to a packaging tank, and the packaging tank contains a storage tank. The top of the storage tank is welded with a drain pipe connected to the connecting pipe B, and a rotating ring B is movably connected to the middle section of the drain pipe. A drain hole A is opened inside the drain pipe at the bottom of the rotating ring B, and a drain hole B is vertically opened inside the rotating ring B. A connecting arm is horizontally fixed on the side of the rotating ring and inserted into the card plate.

[0006] By adopting the above technical solution, the liquid storage tank is used to store liquid hydrogen peroxide raw material for oxygen production. The rotating ring B can rotate inside the drain pipe to adjust the opening and closing of the drain pipe. When the liquid storage tank is installed at the bottom of the mixing tank, the connecting arm on the side of the rotating ring B is inserted into the position between the clamping plates. The drain pipe is kept in a normally closed state by using a torsion spring. When it is necessary to inject liquid raw material into the mixing tank, the mixing tank is inverted so that the liquid storage tank is on top and the slider is slid. The angle of the rotating ring B is adjusted by the clamping plate. After the drain hole A and the drain hole B are aligned, the liquid raw material inside the liquid storage tank can be discharged into the mixing tank to complete the injection of liquid raw material.

[0007] Specifically, the top of the mixing tank is detachably connected to a powder tank, and the bottom of the powder tank is integrally formed with a hollow spiral tube that is connected to the connecting pipe A. Powder discharge holes are opened on both sides of the bottom of the hollow spiral tube. The connecting pipe A has an internal thread groove that is screwed into the hollow spiral tube. A rubber ring A is glued to the bottom of the connecting pipe A.

[0008] By adopting the above technical solution, the powder tank is used to store solid manganese dioxide for oxygen production. When installing the powder tank, the mixing tank is inverted, the hollow spiral tube is aligned with the inner thread groove and screwed in. When the hollow spiral tube is in a half-screwed state, the powder discharge hole corresponds exactly to the position of the rubber ring A, preventing the material inside the powder tank from leaking out. When mixing for oxygen production is required, the powder tank is continuously screwed downwards. When it is screwed in, the bottom end of the hollow spiral tube will pass through the inner thread groove and extend into the mixing tank. The solid manganese dioxide inside the powder tank is then discharged from the powder discharge hole and mixed with the liquid material inside the mixing tank to produce oxygen.

[0009] Specifically, an exhaust pipe is vertically fixed to one side of the top of the mixing tank, and a gas outlet pipe is horizontally welded to the side of the middle section of the exhaust pipe. A valve is installed inside the gas outlet pipe, and a rubber tube is inserted into the outlet end of the gas outlet pipe.

[0010] By adopting the above technical solution, when the oxygen generation reaction is started, the outlet pipe is connected through a rubber hose, and then the valve is opened. The oxygen produced by the solid-liquid mixing reaction inside the mixing tank can be discharged from the outlet pipe and flow along the rubber hose, thus achieving continuous oxygen generation and supply. The valve structure controls the opening and closing of the outlet pipe.

[0011] Specifically, the top of the protective tank is detachably connected to a screw cap, and the screw cap has a storage cavity inside. A hollow positioning tube is fixed inside the screw cap, and a rod is vertically inserted inside the hollow positioning tube. A bottom ring and a top ring are fixed to the bottom and top of the rod, respectively. A spring C is installed between the top of the hollow positioning rod and the bottom of the top ring, and the rod passes through the inside of the spring C.

[0012] By adopting the above technical solution, the storage cavity structure inside the screw cap is used to store sodium carbonate powder. Under the action of spring C, the insert rod causes the top ring and bottom ring to close the two ends of the screw cap, so that the storage cavity is in a closed state. Without the application of external force, the powder inside will not leak out. When needed, it can be quickly discharged to neutralize hydrogen peroxide and reduce corrosiveness.

[0013] Specifically, a viewing window is embedded in the inner side of the mixing tank.

[0014] By adopting the above technical solution, the material quantity inside the mixing tank can be viewed and the mixing reaction process can be observed through the viewing window structure on the side of the mixing tank, ensuring that the reaction starts normally.

[0015] Specifically, the packaging can has a vacuum chamber inside, the inner wall of the packaging can is covered with a heat insulation cotton layer, and a fixing ring is fixed at the bottom of the packaging can. A spring A is installed on the top of the fixing ring and a support ring is movably connected through the spring A. The bottom of the liquid storage tank is inserted into the support ring. Limiting holes are opened vertically on both sides of the inside of the fixing ring, and limiting rods inserted into the limiting holes are fixed on both sides of the bottom of the support ring.

[0016] By adopting the above technical solution, the packaging can is equipped with a vacuum chamber inside, which is in a vacuum state when it leaves the factory. Combined with the heat insulation cotton layer structure bonded to the inner wall of the packaging can, it can achieve a good heat preservation effect, reduce the impact of the low temperature environment at high altitudes on the liquid raw materials inside the storage tank, and ensure the shelf life of the liquid raw materials. The top of the fixing ring is equipped with a support ring through spring A. When installing the packaging can, it is first inserted vertically from the bottom of the mixing tank. During the insertion process, it is ensured that the connecting arm at the top of the storage tank is aligned with the clamping plate. After alignment, the packaging can is screwed on. At this time, spring A is compressed until the packaging can is screwed into place and fixed to the bottom of the mixing tank, thus completing the installation and fixing of the storage tank. The limiting hole and the limiting rod cooperate to prevent the support ring structure from rotating independently. During the screwing of the packaging can, the packaging can, fixing ring and support ring rotate synchronously.

[0017] Specifically, a pressure relief hole is provided inside the exhaust pipe at the top of the outlet pipe, and a piston is movably connected to the top of the inner wall of the exhaust pipe by a spring B, with the bottom end of the piston inserted into the pressure relief hole. A pressure relief pipe is horizontally fixed on the side of the exhaust pipe at the top of the piston.

[0018] By adopting the above technical solution, under normal use, the piston is inserted into the pressure relief hole under the action of spring B, ensuring the closure of the pressure relief hole. During the oxygen production and supply process, if the oxygen production rate is too fast or the valve opening and closing range is too small, resulting in a low exhaust rate, as the gas pressure inside the mixing tank continues to increase, the piston will be pushed so that the oxygen inside can be discharged from the pressure relief hole, avoiding the problem of excessive pressure inside the mixing tank.

[0019] Specifically, the protective tank has a groove on the top side and a rubber tube passes through the groove. A rubber ring B is bonded to the top of the screw cap and the top of the top ring fits the bottom of the rubber ring B. A sealing ring is bonded to the bottom of the inner wall of the screw cap and an annular cavity is formed inside the sealing ring. The outer circumference of the bottom ring is inserted into the annular cavity.

[0020] By adopting the above technical solution, when the screw cap is closed, the hose can pass through the groove to extend to the outside of the protective tank, so that the protective tank can still supply oxygen normally when closed. Under normal use, the top ring fits against the bottom of the rubber ring B to ensure the seal of the top of the screw cap. At the same time, the bottom ring is inserted into the ring cavity to fit against the sealing ring and maintain the seal of the bottom of the screw cap. When hydrogen peroxide material leaks inside the protective tank, the top ring can be pressed down quickly and forcefully, causing the insert rod to move the bottom ring down and break through to the outside of the sealing ring. At this time, the sodium carbonate powder inside the storage cavity can be discharged into the protective tank and mixed with the leaked hydrogen peroxide solution inside, which can neutralize and reduce corrosiveness, and reduce the impact of liquid material leakage.

[0021] The beneficial effects of this invention are: (1) The portable high-altitude emergency oxygen supply device based on solid-liquid reaction described in this invention has a mixing tank as its main structure, which is used to mix solid and liquid raw materials. The storage tank is used to store liquid hydrogen peroxide for oxygen production. The rotating ring B can rotate inside the drain pipe to adjust the opening and closing of the drain pipe. When it is necessary to inject liquid raw materials into the mixing tank, the mixing tank is inverted so that the storage tank is on top and the slider is slid. The angle of the rotating ring B is adjusted by the clamping plate. After the drain hole A and the drain hole B are aligned, the liquid raw materials inside the storage tank can be discharged into the mixing tank to complete the liquid raw material injection. The powder tank is used to store solid manganese dioxide for oxygen production. When mixing for oxygen production is required, the powder tank is continuously screwed downwards. Once screwed in, the bottom end of the hollow spiral tube extends through the inner spiral groove into the mixing tank. The solid manganese dioxide inside the powder tank is then discharged from the powder discharge hole and mixed with the liquid material inside the mixing tank to produce oxygen. The end of the oxygen suction hose is inserted into the outlet pipe and the valve is opened to provide continuous oxygen supply. The device is small in size and portable. Oxygen production can be started with just a few steps when needed. It is easy to operate and suitable for rapid oxygen production and continuous oxygen supply in high-altitude environments.

[0022] (2) The portable high-altitude emergency oxygen supply device based on solid-liquid reaction described in this invention has a storage cavity structure inside the screw cap for storing sodium carbonate powder. Under the action of spring C, the insert rod causes the top ring and bottom ring to close the two ends of the screw cap respectively, so that the storage cavity is in a closed state. Without the application of external force, the powder inside will not leak out. Under normal use, the top ring fits the bottom of the rubber ring B to ensure the sealing of the top of the screw cap. At the same time, the bottom ring is inserted into the ring cavity to fit the sealing ring and keep the bottom of the screw cap sealed. When hydrogen peroxide material leaks inside the protective tank, the top ring can be pressed down quickly, causing the insert rod to drive the bottom ring to move down and break through to the outside of the sealing ring. At this time, the sodium carbonate powder inside the storage cavity can be discharged into the protective tank and mixed with the leaked hydrogen peroxide solution inside, which plays a role in neutralizing and reducing corrosiveness, and reducing the impact of liquid material leakage.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] Example 1: The technical solution adopted by the present invention to solve its technical problem is a portable high-altitude emergency oxygen supply device based on solid-liquid reaction, including a mixing tank 1 and a protective tank 5. The mixing tank 1 has an arc-shaped guide groove 102 on its side and a slider 103 is slidably connected inside the arc-shaped guide groove 102. The top and bottom of the mixing tank 1 are respectively provided with connecting pipe A104 and connecting pipe B105. A fixing rod 106 is vertically fixed at the bottom of the mixing tank 1, located on the side of the connecting pipe B105. A rotating ring A107 is movably connected to the bottom of the outer periphery of the fixing rod 106. A torsion spring 108 is installed between the bottom of the fixing rod 106 and the top of the rotating ring A107. A connecting rod 109 is horizontally fixed on the side of the rotating ring A107 and connected to the slider 103 through the connecting rod 109. A clamping plate 110 is symmetrically fixed on both sides of the bottom end of the fixing rod 106.

[0028] In use, the mixing tank 1 is the main structure of this device, which is used to mix solid and liquid raw materials. The slider 103 can slide inside the arc-shaped guide groove 102, and when it slides, it will drive the rotation of the clamping plate 110. The torsion spring 108 is installed at the mounting position of the rotating ring A107 to play a reset role. When the slider 103 slides, the torsion spring 108 will be compressed. After the slider 103 is released, the torsion spring 108 can drive the slider 103 to automatically reset. The clamping plate 110 is used to dock with the opening and closing end of the liquid storage tank 208.

[0029] Specifically, the bottom of the mixing tank 1 is detachably connected to the packaging tank 2, and the packaging tank 2 has a built-in liquid storage tank 208. The top of the liquid storage tank 208 is welded with a drain pipe 209 connected to the connecting pipe B105, and the middle section of the drain pipe 209 is movably connected to a rotating ring B210. The drain pipe 209 has a drain hole A211 at the bottom of the rotating ring B210, and the rotating ring B210 has a vertical drain hole B212. The side of the rotating ring is horizontally fixed with a connecting arm 213 that is inserted into the card plate 110.

[0030] In use, the storage tank 208 is used to store liquid hydrogen peroxide for oxygen production. The rotating ring B210 can rotate inside the drain pipe 209 to adjust the opening and closing of the drain pipe 209. When the storage tank 208 is installed at the bottom of the mixing tank 1, the connecting arm 213 on the side of the rotating ring B210 is inserted into the position between the inside of the clamping plate 110. The drain pipe 209 is kept in a normally closed state by the torsion spring 108. When it is necessary to inject liquid raw materials into the mixing tank 1, the mixing tank 1 is inverted so that the storage tank 208 is on top and the slider 103 is slid. The angle of the rotating ring B210 is adjusted by the clamping plate 110. After the drain hole A211 and the drain hole B212 are aligned, the liquid raw materials inside the storage tank 208 can be discharged into the mixing tank 1 to complete the injection of liquid raw materials.

[0031] Specifically, the top of the mixing tank 1 is detachably connected to the powder tank 3. The bottom of the powder tank 3 is integrally formed with a hollow spiral tube 301 that is connected to the connecting pipe A104. The bottom of the hollow spiral tube 301 is provided with powder discharge holes 302 on both sides. The connecting pipe A104 is provided with an inner spiral groove 303 that is screwed into the hollow spiral tube 301. A rubber ring A304 is glued to the bottom of the connecting pipe A104.

[0032] In use, the powder tank 3 is used to store solid manganese dioxide for oxygen production. When installing the powder tank 3, the mixing tank 1 is inverted, the hollow screw tube 301 is aligned with the inner screw groove 303 and screwed in. When the hollow screw tube 301 is in a half-screwed state, the powder discharge hole 302 corresponds to the position of the rubber ring A304 to prevent the material inside the powder tank 3 from leaking out. When mixing for oxygen production is required, the powder tank 3 is continuously screwed down. When it is screwed in, the bottom end of the hollow screw tube 301 will pass through the inner screw groove 303 and extend into the mixing tank 1. The solid manganese dioxide inside the powder tank 3 is then discharged from the powder discharge hole 302 and mixed with the liquid material inside the mixing tank 1 to produce oxygen.

[0033] Specifically, the packaging can 2 has a vacuum chamber 201 inside, the inner wall of the packaging can 2 is covered with a heat insulation cotton layer 202, and a fixing ring 203 is fixed at the bottom of the packaging can 2. A spring A204 is installed on the top of the fixing ring 203 and a support ring 205 is movably connected through the spring A204. The bottom of the liquid storage tank 208 is inserted into the support ring 205. Limiting holes 206 are opened vertically on both sides of the inside of the fixing ring 203, and limiting rods 207 inserted into the limiting holes 206 are fixed on both sides of the bottom of the support ring 205.

[0034] During use, the packaging can 2 has a vacuum chamber 201 inside, which is vacuumed when it leaves the factory. Combined with the insulation cotton layer 202 bonded to the inner wall of the packaging can 2, it can achieve a good insulation effect, reduce the impact of the low temperature environment at high altitudes on the liquid raw materials inside the storage tank 208, and ensure the shelf life of the liquid raw materials. The top of the fixing ring 203 is equipped with the support ring 205 by spring A204. When installing the packaging can 2, first insert it vertically from the bottom of the mixing tank 1. During the insertion process, ensure that the connecting arm 213 at the top of the storage tank 208 is aligned with the clamping plate 110. After docking, turn the packaging can 2. At this time, the spring A204 is compressed until the packaging can 2 is screwed into and fixed to the bottom of the mixing tank 1, thus completing the installation and fixing of the storage tank 208. The limiting hole 206 cooperates with the limiting rod 207 to prevent the support ring 205 structure from rotating independently. During the turning of the packaging can 2, the packaging can 2, the fixing ring 203 and the support ring 205 rotate synchronously.

[0035] Specifically, a pressure relief hole 404 is provided inside the exhaust pipe 4 at the top of the exhaust pipe 401. A piston 406 is movably connected to the top of the inner wall of the exhaust pipe 4 via a spring B405, and the bottom end of the piston 406 is inserted into the pressure relief hole 404. A pressure relief pipe 407 is horizontally fixed on the side of the exhaust pipe 4 at the top of the piston 406.

[0036] During normal use, piston 406 is inserted into pressure relief hole 404 under the action of spring B405, ensuring the closure of pressure relief hole 404. During oxygen production and supply, if the oxygen production rate is too fast or the valve 402 opens and closes too little, resulting in a low exhaust rate, as the gas pressure inside mixing tank 1 continues to increase, piston 406 will be pushed to allow the oxygen inside to be discharged from pressure relief hole 404, thus avoiding the problem of excessive pressure inside mixing tank 1.

[0037] In use, the mixing tank 1 is the main structure of this device, and its interior is used for mixing solid and liquid raw materials. The slider 103 can slide inside the arc-shaped guide groove 102, and its sliding will drive the rotation of the clamping plate 110. The torsion spring 108 is installed at the mounting position of the rotating ring A107 to perform a reset function. When the slider 103 slides, the torsion spring 108 is compressed. After the slider 103 is released, the torsion spring 108 can drive the slider 103 to automatically reset. The clamping plate 110 is used to dock with the opening and closing end of the liquid storage tank 208. The storage tank 208 is used to store liquid hydrogen peroxide for oxygen production. The rotating ring B210 can rotate inside the drain pipe 209 to adjust its opening and closing. When the storage tank 208 is installed at the bottom of the mixing tank 1, the connecting arm 213 on the side of the rotating ring B210 is inserted into the position between the two sides of the clamping plate 110. The torsion spring 108 keeps the drain pipe 209 normally closed. When liquid raw material needs to be injected into the mixing tank 1, the mixing tank 1 is inverted so that the storage tank 208 is at the top, and the sliding block 103 slides, driving the rotating ring B210 through the clamping plate 110. After adjusting the angle to 0, aligning drain holes A211 and B212, the liquid raw material inside the storage tank 208 can be discharged into the mixing tank 1 to complete the liquid raw material injection. The powder tank 3 is used to store solid manganese dioxide for oxygen production. When installing the powder tank 3, invert the mixing tank 1, align the hollow screw tube 301 with the inner screw groove 303 and screw it in. When the hollow screw tube 301 is in the half-screwed state, the powder discharge hole 302 corresponds exactly to the position of the rubber ring A304 to prevent material leakage from the powder tank 3. When mixing for oxygen production is required, continue to screw downwards. When the powder tank 3 is screwed in, the bottom end of the hollow screw tube 301 will extend through the inner screw groove 303 into the mixing tank 1. The solid manganese dioxide material inside the powder tank 3 will be discharged from the powder discharge hole 302 and mixed with the liquid material inside the mixing tank 1 to produce oxygen. The end of the oxygen suction tube 403 is inserted into the air outlet pipe 401 and the valve 402 is opened to provide continuous oxygen supply. The device is small in size and portable. When oxygen production is needed, it can be started with just a few steps. It is easy to operate and suitable for rapid oxygen production and continuous oxygen supply in high-altitude environments.

[0038] Example 2: The technical solution adopted by the present invention to solve its technical problem is a portable high-altitude emergency oxygen supply device based on solid-liquid reaction, including a mixing tank 1 and a protective tank 5. The mixing tank 1 has an arc-shaped guide groove 102 on its side and a slider 103 is slidably connected inside the arc-shaped guide groove 102. The top and bottom of the mixing tank 1 are respectively provided with connecting pipe A104 and connecting pipe B105. A fixing rod 106 is vertically fixed at the bottom of the mixing tank 1, located on the side of the connecting pipe B105. A rotating ring A107 is movably connected to the bottom of the outer periphery of the fixing rod 106. A torsion spring 108 is installed between the bottom of the fixing rod 106 and the top of the rotating ring A107. A connecting rod 109 is horizontally fixed on the side of the rotating ring A107 and connected to the slider 103 through the connecting rod 109. A clamping plate 110 is symmetrically fixed on both sides of the bottom end of the fixing rod 106.

[0039] In use, the mixing tank 1 is the main structure of this device, which is used to mix solid and liquid raw materials. The slider 103 can slide inside the arc-shaped guide groove 102, and when it slides, it will drive the rotation of the clamping plate 110. The torsion spring 108 is installed at the mounting position of the rotating ring A107 to play a reset role. When the slider 103 slides, the torsion spring 108 will be compressed. After the slider 103 is released, the torsion spring 108 can drive the slider 103 to automatically reset. The clamping plate 110 is used to dock with the opening and closing end of the liquid storage tank 208.

[0040] Specifically, an exhaust pipe 4 is vertically fixed on one side of the top of the mixing tank 1, and an outlet pipe 401 is horizontally welded to the side of the middle section of the exhaust pipe 4. A valve 402 is installed inside the outlet pipe 401, and a rubber tube 403 is inserted into the discharge end of the outlet pipe 401.

[0041] When in use, after the oxygen generation reaction is started, the outlet pipe 401 is connected through the rubber hose 403, and then the valve 402 is opened. The oxygen produced by the solid-liquid mixing reaction inside the mixing tank 1 can be discharged from the outlet pipe 401 and flow along the rubber hose 403 to achieve continuous oxygen generation and supply. The valve 402 controls the opening and closing of the outlet pipe 401.

[0042] Specifically, the top of the protective tank 5 is detachably connected to a screw cap 6, and the screw cap 6 has a storage cavity 605 inside. A hollow positioning tube 601 is fixed inside the screw cap 6, and a rod 603 is vertically inserted inside the hollow positioning tube 601. A bottom ring 604 and a top ring 607 are fixed to the bottom and top of the rod 603, respectively. A spring C602 is installed between the top of the hollow positioning rod and the bottom of the top ring 607, and the rod 603 passes through the inside of the spring C602.

[0043] In use, the storage cavity 605 inside the screw cap 6 is used to store sodium carbonate powder. Under the action of the spring C602, the insert rod 603 causes the top ring 607 and the bottom ring 604 to close the two ends of the screw cap 6 respectively, so that the storage cavity 605 is in a closed state. Without the application of external force, the powder inside will not leak out. When needed, it can be quickly discharged to neutralize hydrogen peroxide and reduce corrosiveness.

[0044] Specifically, a viewing window 101 is embedded in the inner side of the mixing tank 1.

[0045] During use, the material quantity inside the mixing tank 1 can be viewed and the mixing reaction process can be observed through the viewing window 101 structure on the side of the mixing tank 1, ensuring that the reaction starts normally.

[0046] Specifically, the protective tank 5 has a groove 501 on the top side and the rubber tube 403 passes through the groove 501. The top of the screw cap 6 is bonded with a rubber ring B606 and the top of the top ring 607 is attached to the bottom of the rubber ring B606. The bottom of the inner wall of the screw cap 6 is bonded with a sealing ring 608 and the sealing ring 608 has an annular cavity 609. The outer circumference of the bottom ring 604 is inserted into the annular cavity 609.

[0047] When in use, after the screw cap 6 is closed, the hose 403 can pass through the groove 501 to extend to the outside of the protective tank 5, so that the protective tank 5 can still supply oxygen normally when closed. Under normal use, the top ring 607 fits against the bottom of the rubber ring B606 to ensure the seal of the top of the screw cap 6. At the same time, the bottom ring 604 is inserted into the ring cavity 609 to fit against the sealing ring 608, keeping the bottom of the screw cap 6 sealed. When hydrogen peroxide material leaks inside the protective tank 5, the top ring 607 can be pressed down quickly, causing the insert rod 603 to drive the bottom ring 604 down to break through to the outside of the sealing ring 608. At this time, the sodium carbonate powder inside the storage cavity 605 can be discharged into the protective tank 5 and mixed with the leaked hydrogen peroxide solution inside, which plays a role in neutralizing and reducing corrosiveness, and reducing the impact of liquid material leakage.

At the same time, the bottom ring 604 is inserted into the ring cavity 609 and attached to the sealing ring 608 to maintain the seal of the bottom of the screw cap 6. When hydrogen peroxide material leaks inside the protective tank 5, the top ring 607 can be pressed down quickly and forcefully, causing the insert rod 603 to drive the bottom ring 604 to move down and break through to the outside of the sealing ring 608. At this time, the sodium carbonate powder inside the storage cavity 605 can be discharged into the protective tank 5 and mixed with the leaked hydrogen peroxide solution inside, which plays a role in neutralizing and reducing corrosiveness, reducing the impact of liquid material leakage, and improving the overall safety of the device.
