Description

Technical Field

[0001] This utility model belongs to the technical field of breathing oxygen supplementation devices, and specifically relates to a breathing oxygen supplementation device for high-altitude environments. Background Technology

[0002] When using a respirator, it is generally filled with potassium superoxide oxygenating agent inside the oxygen generating tank. Potassium superoxide is widely used as a chemical oxygen generating agent in fields such as spaceflight, submarine navigation, mine self-rescue devices, seabed exploration, high-altitude operations, fire fighting, and medical and health care.

[0003] The reaction principle of potassium superoxide oxygen generator is to absorb the carbon dioxide and water vapor exhaled by the user, thereby releasing oxygen. In addition, the potassium superoxide filled in the respirator should be cleaned up in time after use to avoid the formation of hard clumps after long-term use.

[0004] In the existing technology, when a breathing apparatus is in use, the air flowing inside the apparatus can cause the potassium superoxide residue inside the apparatus to flow as well. When the breathing apparatus is used underwater, the potassium superoxide residue can easily enter the mouth with breathing, causing choking and potentially entering the respiratory tract, thus affecting the health of the user. Utility Model Content

[0005] In view of the problem that when a respirator is in use, the air flowing inside can cause the potassium superoxide residue packed inside the respirator to flow, which can easily enter the mouth during breathing when the respirator is used underwater, causing choking and potentially entering the respiratory tract, thus affecting the health of the user, this utility model proposes a breathing oxygen supplementation device for high-altitude environments to overcome the above-mentioned technical problems existing in related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a breathing oxygen supplementation device for high-altitude environments, comprising a tank:

[0008] The tank is equipped with connecting components, snap-fit ​​components, filtering components, and reaction components.

[0009] A connecting component, one end of which is fixedly installed to one end of the tank body, so that the connecting component can cooperate with the tank body to circulate oxygen.

[0010] A snap-fit ​​component is slidably disposed within the outer surface of a connecting component, thereby linearly restricting the position of the connecting component by the snap-fit ​​component.

[0011] The filter assembly has one side that fits against the side of the connecting assembly so that the filter assembly filters the air inside the tank.

[0012] The reaction assembly has its outer surface sealed to the inside of the tank so that the reaction assembly reacts with the air entering the tank to produce oxygen.

[0013] Furthermore, the connecting assembly includes a sleeve, one end of which is fixedly connected to one side of the tank body, a limiting plate is slidably connected inside the sleeve, and a connecting pipe is fixedly connected inside the limiting plate.

[0014] Furthermore, the snap-fit ​​assembly includes a snap-fit ​​groove and a connecting plate. The snap-fit ​​groove is formed inside the sleeve, and the inside of the connecting plate is rotatably connected to the outer surface of the connecting tube. A spring is fixedly connected to one side of the connecting plate, and a connecting cap is fixedly connected to one end of the spring.

[0015] Furthermore, the snap-fit ​​assembly also includes a snap-fit ​​block and a sealing cylinder. One side of the snap-fit ​​block is fixedly connected to the inner wall of the connecting cap, and the outer surface of the snap-fit ​​block is snap-fitted into the inside of the snap-fit ​​groove. One end of the sealing cylinder is fixedly connected to one side of the connecting cap, and the inside of the sealing cylinder is slidably disposed with the outer surface of the connecting tube.

[0016] Furthermore, the filter assembly includes a support ring, the outer surface of which is fixedly connected to the inner wall of the tank, a sealing ring is fixedly installed inside the support ring, a filter screen is fitted to one side of the sealing ring, a sealing gasket is fixedly installed inside the filter screen, and one side of the sealing gasket is fitted to one side of the limiting plate.

[0017] Furthermore, the reaction assembly includes a partition, the outer surface of which is fixedly connected to the inner wall of the tank, an installation rod is fixedly installed inside the partition, a tank cover is fixedly installed on the outer surface of the installation rod, a sealing strip is fixedly installed on the outer surface of the tank cover, and a handle is fixedly installed on the top of the tank cover.

[0018] Furthermore, the reaction assembly also includes a threaded cylinder, one end of which is fixedly connected to the bottom end of the can lid, and a cartridge is threadedly connected to the threaded surface of the threaded cylinder.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model uses an upper device to blow exhaled carbon dioxide into the interior of a connecting assembly, allowing the carbon dioxide to enter the tank and react with the reaction component to release oxygen. Since there are two sets of connecting assemblies, when one set guides carbon dioxide into the tank, the user can inhale the oxygen produced inside the tank when needed, creating a cycle. When oxygen enters the user's mouth through the other set of connecting assemblies and the upper device, the filter component filters the oxygen before it enters the other set, preventing potassium superoxide residue inside the reaction component and thus avoiding any impact on the user's health.

[0021] 2. This utility model inserts the filter screen into the tank through a sleeve, with one side of the filter screen fitting against one side of the sealing ring. Then, as the connecting pipe is inserted into the sleeve, the connecting pipe drives one side of the connecting plate fixed on the outer surface to fit against the sealing gasket installed inside the filter screen, thereby further improving the sealing between the connecting pipe and the tank. The filter screen also enables it to filter potassium superoxide residue inside the tank.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0032] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0034] Please see Figures 1-6 As shown, this utility model is a breathing oxygen supplementation device for high-altitude environments, including a tank 1:

[0035] The tank body 1 is respectively equipped with a connecting component 2, a snap-fit ​​component 3, a filter component 4, and a reaction component 5;

[0036] Connecting component 2, one end of which is fixedly installed to one end of tank 1, so that connecting component 2 cooperates with tank 1 to circulate oxygen;

[0037] The snap-fit ​​component 3 is slidably disposed inside the outer surface of the connecting component 2, so that the snap-fit ​​component 3 linearly restricts the position of the connecting component 2.

[0038] The filter assembly 4 has one side attached to the side of the connecting assembly 2 so that the filter assembly 4 filters the air inside the tank 1.

[0039] The reaction component 5 has its outer surface sealed to the inside of the tank 1 so that the reaction component 5 reacts with the air entering the tank 1 to produce oxygen.

[0040] In use, the modular reaction components 5 are assembled, and the reaction structure of the reaction components 5 is inserted into the tank 1. The reaction components 5 are then installed in the tank 1. One end of the connecting component 2 is then connected to the upper device, allowing the user to blow exhaled carbon dioxide into the connecting component 2. The carbon dioxide then enters the tank 1 through the connecting component 2, reacting with the carbon dioxide in the reaction components 5 and releasing oxygen. Since there are two sets of connecting components 2, when one set guides carbon dioxide into the tank 1, the user can use the other set to inhale oxygen. The connecting component 2 draws in the oxygen generated inside the tank 1, thus forming a circulation. When the oxygen enters the mouth of the user through another connecting component 2 in conjunction with the upper device, the filter component 4 can filter the oxygen before it enters the interior of the other connecting component 2, thereby preventing potassium superoxide residue inside the reaction component 5. When a lot of residue adheres to one side of the filter component 4, the locking component 3 can be pushed and rotated to release the locking structure of the locking component 3, so as to disassemble the internally sliding connecting component 2. This facilitates the disassembly of the filter component 4 attached to one end of the connecting component 2 and the cleaning of the filter component 4.

[0041] This invention allows a user to blow exhaled carbon dioxide into the connecting assembly 2 using an upper device. The carbon dioxide then enters the tank 1 via the connecting assembly 2, causing the reaction assembly 5 to react with the carbon dioxide and release oxygen. Since there are two sets of connecting assemblies 2, when one set guides carbon dioxide into the tank 1, the user can inhale the oxygen produced inside the tank 1 using the other set of connecting assemblies 2, thus creating a cycle. When the oxygen enters the user's mouth via the upper device and the other set of connecting assemblies 2, the filter assembly 4 filters the oxygen before it enters the other set of connecting assemblies 2, preventing potassium superoxide residue inside the reaction assembly 5 and thus avoiding any impact on the user's health.

[0042] In one embodiment, the connecting component 2 includes a sleeve 201, one end of which is fixedly connected to one side of the tank 1, and a limiting plate 202 is slidably connected inside the sleeve 201. A connecting pipe 203 is fixedly connected inside the limiting plate 202.

[0043] By connecting the connecting tube 203 to the external upper device, the upper device can be placed around the user's neck, with the breathing port inside the mouth. Then, in conjunction with the bidirectional pipe of the upper device, the exhaled carbon dioxide enters the interior of the tank 1 through one set of connecting tubes 203. When inhaling, the oxygen generated inside the tank 1 can be drawn into the mouth through the other set of connecting tubes 203. The sleeve 201 and the limiting plate 202 ensure the sealing between the connecting tube 203 and the tank 1.

[0044] In one embodiment, the snap-fit ​​assembly 3 includes a snap-fit ​​groove 301 and a connecting plate 302. The snap-fit ​​groove 301 is formed inside the sleeve 201. The interior of the connecting plate 302 is rotatably connected to the outer surface of the connecting tube 203. A spring 303 is fixedly connected to one side of the connecting plate 302, and a connecting cap 304 is fixedly connected to one end of the spring 303.

[0045] The snap-fit ​​assembly 3 also includes a snap-fit ​​block 305 and a sealing cylinder 306. One side of the snap-fit ​​block 305 is fixedly connected to the inner wall of the connecting cap 304, and the outer surface of the snap-fit ​​block 305 is snap-fitted to the inside of the snap-fit ​​groove 301. One end of the sealing cylinder 306 is fixedly connected to one side of the connecting cap 304, and the inside of the sealing cylinder 306 is slidably disposed with the outer surface of the connecting pipe 203.

[0046] When the connecting tube 203 is inserted into the sleeve 201, the connecting tube 203 can move the sealing cylinder 306, which is slidably disposed on the outer surface, to one side of the sleeve 201. Then, the sealing cylinder 306 is pushed to move closer to the sleeve 201, thereby causing the sealing cylinder 306 to move the snap-fit ​​block 305, which is fixed on the inner wall, into the snap-fit ​​groove 301. When the sealing cylinder 306 moves, it can cause the spring 303, which is fixed on one side, to be stretched. Thus, when the snap-fit ​​block 305 enters the snap-fit ​​groove 301, the contraction stress of the spring 303, together with the sealing cylinder 306, causes the snap-fit ​​block 305 to snap into the inside of the snap-fit ​​groove 301. At the same time, the tension at the other end of the spring 303 acts on one side of the connecting plate 302, thereby causing the connecting plate 302 to drive the internally rotating connecting tube 203 to fit tightly into the inside of the sleeve 201.

[0047] In one embodiment, the filter assembly 4 includes a support ring 401. The outer surface of the support ring 401 is fixedly connected to the inner wall of the tank 1. A sealing ring 402 is fixedly installed inside the support ring 401. A filter screen 403 is attached to one side of the sealing ring 402. A sealing gasket 404 is fixedly installed inside the filter screen 403. One side of the sealing gasket 404 is attached to one side of the limiting plate 202.

[0048] By inserting the filter screen 403 into the tank 1 through the sleeve 201 and making one side of the filter screen 403 fit against one side of the sealing ring 402, and then inserting the connecting pipe 203 into the sleeve 201, the connecting pipe 203 can drive one side of the connecting plate 302 fixed on the outer surface to fit against the sealing gasket 404 installed inside the filter screen 403, thereby further improving the sealing between the connecting pipe 203 and the tank 1. The filter screen 403 can also filter the potassium superoxide residue inside the tank 1.

[0049] In one embodiment, the reaction assembly 5 includes a partition 501, the outer surface of which is fixedly connected to the inner wall of the tank 1, an installation rod 502 is fixedly installed inside the partition 501, a tank cover 503 is fixedly installed on the outer surface of the installation rod 502, a sealing strip 504 is fixedly installed on the outer surface of the tank cover 503, and a handle 505 is fixedly installed on the top of the tank cover 503.

[0050] The reaction assembly 5 also includes a threaded cylinder 506, one end of which is fixedly connected to the bottom end of the can lid 503, and a cartridge 507 is threadedly connected to the threaded surface of the threaded cylinder 506.

[0051] By taking out two sets of cartridges 507, threading one end of each set of cartridges 507 onto the outer surface of the threaded cylinder 506, and then inserting the cartridges 507 into the interior of the tank body 1, so that the two sets of cartridges 507 are symmetrically arranged on both sides of the partition 501, the gas entering the tank body 1 can move in a U-shape, thereby increasing the time the gas spends inside the tank body 1, and thus improving the reaction between the gas and the potassium superoxide inside the cartridges 507. By fitting the inside of the tank cover 503 onto the outer surface of the mounting rod 502, and then installing the tank cover 503 at the top of the tank body 1 with the matching bolts, the sealing strip 504 can ensure the sealing between the tank cover 503 and the tank body 1.

[0052] Through the above technical solution, 1. By using the upper device to blow exhaled carbon dioxide into the interior of the connecting component 2, the carbon dioxide enters the interior of the tank 1 with the connecting component 2, and the reaction component 5 reacts with the carbon dioxide to release oxygen. Since there are two sets of connecting components 2, when one set of connecting components 2 guides carbon dioxide into the interior of the tank 1, when the user needs to inhale oxygen, the other set of connecting components 2 can be used to inhale the oxygen generated inside the tank 1, thus forming a cycle. When the oxygen enters the other set of connecting components 2 and enters the user's mouth with the upper device, the filter component 4 can filter the oxygen before it enters the interior of the other set of connecting components 2, thereby avoiding potassium superoxide residue inside the reaction component 5 and thus avoiding any impact on the user's health.

[0053] 2. By inserting the filter screen 403 into the tank 1 through the sleeve 201 and making one side of the filter screen 403 fit against one side of the sealing ring 402, and then inserting the connecting pipe 203 into the sleeve 201, the connecting pipe 203 can drive one side of the connecting plate 302 fixed on the outer surface to fit against the sealing gasket 404 installed inside the filter screen 403, thereby further improving the sealing between the connecting pipe 203 and the tank 1. The filter screen 403 can filter the potassium superoxide residue inside the tank 1.
