Description

Technical Field

[0001] This utility model relates to the technical field of oxygen inhalation devices, specifically a convenient chemical oxygen inhalation device. Background Technology

[0002] A chemical oxygen respirator is a personal respiratory protective device made using the principle of generating oxygen with chemical agents. During the entire process of use, breathing is isolated from the outside world, and the wearer is not harmed by any toxic or harmful gases or fumes. Therefore, it is suitable for various toxic and harmful gas and oxygen-deficient environments. A chemical oxygen respirator generally consists of four parts: a mask, a breathing mask, an oxygen generator, and an air bag. It adopts two pathways: reciprocating or circulating. The water vapor and carbon dioxide in the wearer's exhaled air react chemically with the oxygen generator in the oxygen generator to release oxygen for the wearer to breathe.

[0003] Existing chemical oxygen respirators have their masks, breathing masks, oxygen tanks, and air bags stored separately and connected only when needed. While this facilitates maintenance of each component, it also makes it inconvenient to find the components when traveling (such as for tourism). Furthermore, the dispersed nature of the components increases the risk of contamination.

[0004] Therefore, there is an urgent need for a convenient chemical oxygen inhalation device to solve the above problems. Utility Model Content

[0007] The breathing mask compartment is equipped with a breathing mask, and the breathing mask has two connecting tubes located away from the face. One side of the breathing mask is connected to the two connecting tubes via a T-junction.

[0008] The main compartment is equipped with an exhalation tube, an inhalation tube, and an oxygen generator. The exhalation tube is connected to the oxygen generator via a first connector. The oxygen generator has a heat dissipation and heat protection partition on its side wall. The oxygen generator has a second connector at the end near the airbag storage compartment.

[0009] The airbag storage compartment is equipped with an airbag, which is connected to the oxygen generator via a second connector, and the airbag outlet is connected to the suction pipe via a third connector.

[0010] The storage tube has an adjustable shoulder strap on its side wall.

[0011] The storage cylinder has multiple equidistant heat dissipation holes near the side wall of the main compartment.

[0012] The two connecting tubes are provided with locking assemblies for locking the exhalation tube and the inhalation tube. The locking assembly includes a fixing tube fixedly connected to the end of the connecting tube away from the breathing mask. The side wall of the fixing tube has multiple locking holes, and each locking hole has a locking ball. The end of the exhalation tube and the inhalation tube near the fixing tube is fixedly connected to the locking tube. The side wall of the locking tube has an annular hole. The fixing tube is provided with a driving assembly for driving each locking ball.

[0013] Each of the locking holes has a through hole on its bottom wall, and the diameter of each through hole is smaller than the diameter of the locking ball.

[0014] The drive assembly includes a drive tube slidably connected to the side wall of the connecting tube. A drive ring is fixedly connected to the inner wall of the drive tube near each locking ball. A spring is sleeved on the side wall of the fixed tube.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-5 The illustrated portable chemical oxygen inhalation device includes a storage cylinder 101 and a storage top cover 102 and a storage bottom cover 103 that are snapped together at both ends of the storage cylinder 101. It also includes a breathing mask compartment 2, a main compartment 3 and an airbag storage compartment 4 disposed inside the storage cylinder 101.

[0027] The breathing mask compartment 2 is equipped with a breathing mask 201. The breathing mask 201 is provided with two connecting tubes 202 away from the face. One side of the breathing mask 201 is connected to the two connecting tubes 202 through a three-way tube 203.

[0028] The main chamber 3 is equipped with an exhalation tube 301, an inhalation tube 303, and an oxygen generator 304 for oxygen generation. The exhalation tube 301 is connected to the oxygen generator 304 via a first connector 302. The side wall of the oxygen generator 304 is equipped with a heat-dissipating and heat-prevention partition 305. The heat-dissipating and heat-prevention partition 305 uses high-efficiency heat-insulating materials, such as Class A heat-insulating fireproof glass. These materials can maintain a low heat transfer rate in high-temperature environments, effectively blocking heat transfer. The end of the oxygen generator 304 near the airbag storage compartment 4 is equipped with a second connector 306. The exhalation tube 301 and the inhalation tube 303 are corrugated pipes. Figure 3 The image shown is of the stored state. Furthermore, what is even more optimized is that the exhalation tube 301 and the inhalation tube 303 can be not only corrugated tubes, but also other tubes that are easy to store. No single limitation is made here.

[0029] The airbag storage compartment 4 contains an airbag 402, and the airbag 402 is in Figure 3 The image shows the airbag 402 in its stored state. The airbag 402 is connected to the oxygen tank 304 via the second connector 306, and the air outlet of the airbag 402 is connected to the suction pipe 303 via the third connector 401.

[0030] The storage tube 101 has an adjustable shoulder strap 10 on its side wall, making it convenient to carry when traveling.

[0031] It should be noted that by storing the various components of the chemical oxygen respirator through the storage tube 101 and the storage top cover 102, the components are placed in a centralized manner, which not only provides convenience for carrying when going out, such as for travel, but also reduces the risk of contamination of the various components of the chemical oxygen respirator by utilizing the protection of the storage tube 101.

[0032] It is worth noting that the first connector 302, the second connector 306, and the third connector 401 can be the same connecting component, such as a clamp, or they can be different connecting components. No specific limitation is made here. Since the first connector 302, the second connector 306, and the third connector 401 are not frequently disassembled during normal use, their main function is to ensure a secure fixation.

[0033] Further optimization: The components of the chemical oxygen respirator are detachable and placed inside the storage tube 101, thus ensuring the convenience of maintenance and upkeep of each component.

[0034] Please see Figure 1 The storage tube 101 shown in the figure has multiple heat dissipation holes 6 arranged at equal intervals near the side wall of the main compartment 3;

[0035] It should be noted here that the heat dissipation hole 6 is used to dissipate heat from the oxygen generation tank 304 during the chemical reaction.

[0036] Working principle: When using this chemical oxygen respirator, first open the storage top cover 102, then take out the breathing mask 201 from the storage tube 101. After taking out the breathing mask 201 from the storage tube 101, the exhalation tube 301 and the inhalation tube 303 can be connected to the breathing mask 201 using the locking assembly.

[0037] After connecting the exhalation tube 301 and the inhalation tube 303 to the breathing mask 201, open the storage bottom cover 103 and release the air bag 402 from the air bag storage compartment 4. Then, the breathing mask 201 can be put on the user's face. When the user exhales, the exhaled gas enters the oxygen generator 304 through the breathing mask 201 and the exhalation tube 301. After a chemical reaction, the oxygen generator 304 produces oxygen. The oxygen enters the air bag 402 from the bottom of the oxygen generator 304. When the user inhales, the oxygen in the air bag 402 will enter the user's body through the inhalation tube 303, thus realizing a cyclic oxygen generation and inhalation.

[0038] After the user finishes inhaling oxygen, the connection between the exhalation tube 301 and the inhalation tube 303 and the breathing mask 201 is released using the drive assembly. Then, the exhalation tube 301, the inhalation tube 303, the breathing mask 201, and the air bag are placed into the storage tube 101, and the storage top cover 102 and the storage bottom cover 103 are locked in place. This completes the storage of all components of the chemical oxygen respirator, making it convenient to carry when traveling, and also reduces the risk of contamination of the chemical oxygen respirator components by using the protection of the storage tube 101.

[0039] Example 2

[0040] Please see Figure 4 and Figure 5 This embodiment further illustrates Example 1. The two connecting tubes 202 in the figure are provided with locking components for locking the exhalation tube 301 and the inhalation tube 303. The locking components include a fixing tube 701 fixedly connected to the end of the connecting tube 202 away from the breathing mask 201. The side wall of the fixing tube 701 is provided with a plurality of locking holes 702. Each locking hole 702 is provided with a locking ball 703. The end of the exhalation tube 301 and the inhalation tube 303 near the fixing tube 701 is fixedly connected to a locking tube 704. The side wall of the locking tube 704 is provided with an annular hole 705. A sealing ring is sleeved on the side wall of the locking tube 704 to improve the connection sealing between the locking tube 704 and the fixing tube 701. The fixing tube 701 is provided with a driving component for driving each locking ball 703.

[0041] It should be noted that when connecting the exhalation tube 301 or inhalation tube 303 to the breathing mask 201, first align the locking tube 704 with the fixing tube 701, then use the drive assembly to release the pressure on each locking ball 703. After releasing the pressure on each locking ball 703, the locking tube 704 can be inserted into the fixing tube 701. After inserting the locking tube 704 into the fixing tube 701, use the drive assembly to press each locking ball 703, thereby causing each locking ball 703 to enter the annular hole 705 and engage with the annular hole. The bottom walls of tubes 705 abut against each other, thereby utilizing the clamping action of each locking ball 703 to achieve locking and limiting between the locking tube 704 and the fixing tube 701, further connecting and locking the exhalation tube 301 or the inhalation tube 303. The operation is simple and convenient. While realizing the quick connection and disassembly of the exhalation tube 301 or the inhalation tube 303 and the breathing mask 201, it ensures the firmness of the exhalation tube 301 or the inhalation tube 303 during use, thereby preventing the exhalation tube 301 or the inhalation tube 303 from falling off due to excessive air pressure during exhalation and inhalation.

[0042] Please see Figure 4 and Figure 5 The bottom wall of each locking hole 702 in the figure has a through hole, and the diameter of each through hole is smaller than the diameter of the locking ball 703;

[0043] It should be noted here that the setting of each through hole and the limitation of the diameter of the through hole are used to limit the range of motion of the locking ball 703.

[0044] Please see Figure 4 and Figure 5 The driving assembly shown in the figure includes a driving tube 801 that is slidably connected to the side wall of the connecting tube 202. A driving ring 802 is fixedly connected to the inner wall of the driving tube 801 near each locking ball 703. A spring 803 is sleeved on the side wall of the fixed tube 701. The two ends of the spring 803 are respectively connected to the driving ring 802 and the connecting tube 202. A retaining ring 804 is fixedly connected to the end of the driving tube 801 away from the connecting tube 202.

[0045] It should be noted that, due to the configuration of the drive assembly, when it is necessary to release the locking of the exhalation tube 301 or the inhalation tube 303, simply push the drive tube 801 closer to the connecting tube 202, thereby moving the drive ring 802. This causes the drive ring 802 to release the pressure on each locking ball 703, and thus the locking balls 703 no longer press on the locking tube 704, thereby releasing the locking of the locking tube 704. At this time, the exhalation tube 301 or the inhalation tube 303 can be detached from the connecting tube 202 and stored in the storage tube 101.

[0046] Please see Figure 4 and Figure 5 The two locking tubes 704 shown in the figure are equipped with one-way valves 9;

[0047] It should be noted here that the one-way valve 9 allows for unidirectional flow of exhalation and inhalation. That is, during exhalation, only the exhaled gas can enter the oxygen generator 304 through the exhalation tube 301, while during inhalation, only the oxygen in the air bag 402 can be inhaled through the inhalation tube 303.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
