Description

Technical Field

[0001] This utility model relates to the field of self-rescue device technology, and more specifically, to a self-rescue device with a rapidly replaceable medicine tank. Background Technology

[0002] Compressed oxygen self-rescue devices are self-rescue and escape equipment that uses high-pressure compressed oxygen as an oxygen source. They are mainly used in coal mines, firefighting, and other fields when toxic or harmful gas leaks or oxygen deficiency and asphyxiation occur in the work environment. Personnel on site can escape the disaster area and save themselves by wearing the compressed oxygen self-rescue device. The principle of an isolated compressed oxygen self-rescue device is that in the event of a coal mine accident, opening the cylinder valve allows high-pressure oxygen to be reduced to normal atmospheric pressure by a pressure reducer, and then flows out through the pressure reducer's constant flow port into the breathing bag for breathing. A compressed oxygen self-rescue device includes a breathing bag, an oxygen cylinder, and calcium hydroxide for absorbing carbon dioxide. The calcium hydroxide is generally located in the device's chemical chamber. In related technologies, the user exhales into the breathing bag through a mouthpiece connected to it. The exhaled gas diffuses from the breathing bag into the calcium hydroxide in the chemical chamber, allowing the calcium hydroxide to absorb the carbon dioxide in the gas. Some existing compressed oxygen self-rescue devices have a non-removable or inconveniently removable chemical chamber, leading to difficulties and inconvenience in replacing the chemical (calcium hydroxide) inside the chamber, increasing the cost of chemical replacement.

The first protrusions 2011 and second protrusions 2012 create gaps between the upper and lower parts of the medicine container and the medicine, reducing gas resistance during breathing and improving breathing smoothness. A connecting cavity 6 is provided inside the medicine container 2, and the lower part of the connecting cavity 6 communicates with the lower part of the inner cavity 20. The outer shell 1 is provided with a first connecting post 11 and a second connecting post 12. A first interface 102 is formed inside the first connecting post 11, and a second interface is formed inside the second connecting post 12. A first air guide column 23 is inserted into the inner side of the first connecting post 11, and a second air guide column 23 is inserted into the inner side of the second connecting post 12. The column 24 is inserted into the inner side of the second connecting column 12. The first connecting column 11, the second connecting column 12, the first air guide column 23, and the second air guide column 24 are all hollow annular columns. The inner side of the first air guide column 23 is connected to the connecting cavity 6, and the inner side of the second air guide column 24 is connected to the inner cavity 20. In this embodiment, the oxygen discharged from the compressed oxygen cylinder first enters the air bag, then enters the connecting cavity 6 from the first air guide column 23, and then flows upward into the lower part of the inner cavity 20. After flowing through the drug, it is discharged from the second air guide column 24 to the breathing device for the person to inhale. When the human body exhales gas, the gas returns to the air bag along the original path. During this process, the carbon dioxide exhaled will be absorbed by the drug to maintain the carbon dioxide concentration in the gas from being too high.

[0032] See Figures 1-4A first sealing ring 231 is provided on the outer side of the first air guide column 23, and a first annular groove for installing the first sealing ring 231 is provided on the first air guide column 23. The first sealing ring 231 is sealed against the inner wall of the first connecting column 11. A second sealing ring 241 is provided on the outer side of the second air guide column 24, and a second annular groove for installing the second sealing ring 241 is provided on the second air guide column 24. The second sealing ring 241 is sealed against the inner wall of the second connecting column 12. The medicine compartment adopts a dual breathing port (the breathing ports are formed on the inner side of the first air guide column and the second air guide column respectively) in the same direction, which facilitates the connection with the self-rescue device body when changing the medicine compartment. At the same time, sealing rings are added to the first air guide column and the second air guide column to achieve independent sealing between the outer shell of the self-rescue device body and the medicine compartment. During the use of the self-rescue device, the breathing gas will not exchange with the air in the space around the medicine compartment, forming an independent gas circuit, avoiding harmful gases from entering the breathing gas circuit, and making it safe and reliable to use.

[0033] See Figure 1 and Figure 9 The breathing apparatus 4 is a breathing mouthpiece or breathing mask for human breathing; the reagent is solid calcium hydroxide, specifically, it is cylindrical calcium hydroxide for mining.

[0034] This utility model is a self-rescue device with a quickly replaceable medicine compartment. It has a simple structure and low production cost. The medicine compartment is easy to assemble and disassemble, and convenient to operate, allowing for continued use of the self-rescue device after the medicine compartment is replaced, thus saving costs. After removing the cover plate, the medicine compartment can be removed from the installation cavity, making operation convenient. Several positioning protrusions are provided on the cover plate, which are positioned inside the installation cavity for positioning, preventing the cover plate from shifting after installation. A limiting protrusion is placed on one side of the medicine compartment, making it less likely to shift after installation, increasing the stability and reliability of the self-rescue device. A pull ring is provided at the bottom of the medicine compartment, making it easy to pull out the medicine compartment to complete the disassembly step, reducing the difficulty of operation and increasing the disassembly speed. The bottom cover and the compartment body are ultrasonically welded to improve the sealing and strength of the medicine compartment. Several first protrusions are provided on the upper wall of the inner cavity, and several second protrusions are provided on the lower wall of the inner cavity. The first and second protrusions provide gaps between the medicine and the upper and lower parts of the inner cavity, reducing the gas resistance in the upper and lower parts of the inner cavity during breathing and improving the smoothness of breathing.
