[0054] In the description of this specification, it is necessary to understand that the directional words such as "upper" and "lower" described in the embodiments of the utility model are described at the angles shown in the drawings and should not be understood as limiting the embodiments of the utility model. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0055] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a self-rescuer, comprising a gas cylinder 1, wherein the gas cylinder 1 comprises an inner liner 11 and a fiber layer from the inside to the outside;

[0056] The fiber layer includes a carbon fiber layer 12. The carbon fiber layer 12 includes transverse fiber layers and longitudinal fiber layers alternately arranged along the thickness direction. The fiber direction of the transverse fiber layer is different from the fiber direction of the longitudinal fiber layer.

[0057] In this embodiment, the material of the inner liner 11 can be an aluminum alloy or a thin stainless steel with excellent light weight. The carbon fiber layer 12 is wrapped around the outside of the aluminum alloy, which increases the gas carrying capacity of the inner liner 11 and also has the characteristics of corrosion resistance and light weight. In summary, the gas carrying capacity of the gas cylinder 1 is increased by carbon fiber, and the gas cylinder 1 as a whole has the characteristics of light weight.

[0058] In this embodiment, transverse fiber layers and longitudinal fiber layers are alternately arranged along the thickness direction, and the fiber direction of the transverse fiber layer is different from that of the longitudinal fiber layer. Preferably, the fiber direction of the transverse fiber layer is perpendicular to that of the longitudinal fiber layer. The arrangement of the transverse fiber layer and the longitudinal fiber layer can make the mechanical properties of the entire fiber layer more uniform in all directions, thereby increasing the service life of the material.

[0059] In some embodiments of the present invention, the fiber layer further includes a glass fiber layer 13 , and the glass fiber layer 13 is disposed on a side of the carbon fiber layer 12 away from the inner liner 11 .

[0060] In this embodiment, a glass fiber layer 13 is added outside the carbon fiber. In addition to being lightweight and having excellent mechanical properties, the glass fiber layer 13 also has excellent thermal insulation properties, which can minimize temperature changes of the carbon fiber layer 12, the inner liner 11, and the gas in the inner liner 11.

[0061] Specifically, the thickness of the liner 11 can be 7 mm, the thickness of the transverse fiber layer and the thickness of the longitudinal fiber layer can both be 0.14 mm, the overall thickness of the fiber layer can be 6×0.14 mm, the thickness of the glass fiber layer 13 can be 0.5 mm, and can be composed of two layers of 0.25 mm single-layer glass fibers. Compared with the commonly used ZYX45 oxygen-isolating self-rescuer, the self-rescuer provided by the present application has a 30% reduction in weight, a 20% increase in oxygen storage pressure, a 25% increase in rated protection time, and a 35% increase in oxygen storage capacity.

[0062] like Figure 3As shown, in some embodiments of the utility model, the gas outlet of the gas cylinder 1 is connected with a flow control device 2, and the flow control device 2 includes a main body 21 and an adjusting rod 23. A gas channel 22 is arranged inside the main body 21, and the inlet of the gas channel 22 is connected to the gas cylinder 1. The main body 21 is provided with a through hole, and the cross section of the through hole gradually decreases from the inside to the outside of the main body 21. The adjusting rod 23 penetrates into the gas channel 22 inside the main body 21 through the through hole. A partition 24 is arranged in the gas channel 22, and the partition 24 separates the part of the fluid channel close to the gas outlet into two outlet channels. A sphere 231 is arranged in the middle of the adjusting rod 23, and the sphere 231 is sealed and movably connected to the end of the through hole with a smaller cross section. The part of the adjusting rod 23 located in the gas channel 22 is provided with a baffle;

[0063] By moving the portion of the adjusting rod 23 located outside the main body 21 , the adjusting rod 23 is rotated while sealing the through hole. By moving the adjusting rod 23 , the baffle is blocked or opened to control the flow of the gas channel 22 .

[0064] In the present application, the through hole can be trumpet-shaped or semi-trumpet-shaped. Of course, it can also be other shapes with different cross-sections, which can allow the adjusting rod 23 to rotate in the through hole with the sphere 231 as the axis. The part of the adjusting rod 23 located in the gas channel 22 is provided with a baffle, which can be a plate body mounted on the adjusting rod 23. A partition 24 is provided in the fluid channel to divide the fluid channel outlet into two outlet channels. By toggling the adjusting rod 23, the control can be adjusted to adjust the baffle blockage (semi-blockage) or open an outlet channel, thereby adjusting the flow in the gas channel 22. During normal use, the baffle and the partition 24 cooperate to block an outlet channel. At this time, the gas supply flow rate is 1.2L / min. When the adjusting rod 23 is toggled to separate the baffle and the partition 24, the gas supply flow rate can be increased from 1.2L / min to 60L / min, realizing the ability of manual oxygen supply adjustment, and having the advantage of easy operation.

[0065] In this embodiment, the gas inlet of the gas channel 22 may be provided with a gas cylinder switch knob 25 to control the communication between the gas cylinder 1 and the gas channel 22. The opening force of the gas cylinder switch knob 25 is 40-150N, and turning it can provide gas to the gas channel 22.

[0066] In this embodiment, a barometer may be provided at the gas outlet of the gas channel 22, and the range of the barometer may be 40 MPa, with a measurement accuracy of 2.5. In addition, the scale and indication on the barometer may have a luminous function, which may provide accurate residual gas pressure values ​​for operators in dim environments.

[0067] It should be noted that the conventional flow control device 2 is usually made of alloy material, which is heavy and increases the overall weight of the self-rescuer. The flow control device of the present application uses special plastic as the main material, which has the advantages of light weight and high pressure resistance.

[0068] Please refer to Figure 1 In some embodiments of the utility model, the gas cylinder 1 is connected to an airbag 3, the airbag 3 is used to store gas, the airbag 3 is connected to a respirator 4 and a cleaning tank 5, the cleaning tank 5 is filled with hydroxide, the hydroxide is used to absorb carbon dioxide and release oxygen, the respirator 4 includes an inlet and an exhalation port, the cleaning tank 5 includes an air inlet and an outlet, the inlet of the respirator 4 is connected to the airbag 3, the exhalation port of the respirator 4 is connected to the air inlet of the cleaning tank 5, and the air outlet of the cleaning tank 5 is connected to the airbag 3.

[0069] In this embodiment, the gas in the gas cylinder 1 can be first stored in the airbag 3, and then inhaled into the human body through the respirator 4 from the airbag 3, and the gas exhaled by the human body can pass through the airbag 3 through the pipeline and directly enter the cleaning tank 5. The hydroxide in the cleaning tank 5 can absorb the carbon dioxide in the exhaled gas of the human body and release oxygen into the airbag 3. An exhaust valve can be set on the airbag 3, which automatically exhausts when the pressure in the airbag 3 is 150-300Pa, which has the effect of preventing the pressure in the airbag 3 from being too high. An air-filling pressure plate can also be set on the airbag 3. When the pressure in the airbag 3 is -100--400Pa, it can be turned to accelerate the inflation of air into the airbag 3.

[0070] It is understandable that the gas cylinder 1 can be directly connected to the air bag 3, and can also be connected to the gas cylinder 1 through the flow control device 2 provided by the utility model.

[0071] In this embodiment, the hydroxide may be calcium hydroxide or lithium hydroxide, preferably lithium hydroxide. Lithium hydroxide has a higher conversion efficiency than calcium hydroxide and can absorb 90% of the carbon dioxide exhaled by the human body.

[0072] Please refer to Figure 4 and Figure 5 In some embodiments of the utility model, a columnar medicine tray carrier 6 is provided in the cleaning tank 5, and a plurality of medicine trays 61 are provided along the axial direction of the medicine tray carrier 6.

The exhalation port of the respirator 4 is connected to one end of the medicine tray carrier 6 through an exhalation hose 7, and the other end of the medicine tray carrier 6 is connected to the cleaning tank 5 through a supporting column 9. An air outlet channel 8 is formed between the medicine tray carrier 6 and the cleaning tank 5, and the air outlet channel 8 is connected to the airbag 3.

[0073] In this embodiment, the turbid air exhaled from the respirator 4 directly enters the medicine tray carrier 6 through the exhalation hose 7, and then passes through multiple medicine trays 61 step by step. The medicine trays 61 carry lithium hydroxide 611. When the turbid air passes through the medicine trays 61 through the air holes 612, it fully contacts and reacts with the lithium hydroxide 611 in the medicine trays 61. The lithium hydroxide 611 absorbs carbon dioxide to generate oxygen. Finally, the turbid air passing through the multiple medicine trays 61 step by step becomes oxygen-filled gas, which enters the air bag 3 again through the air outlet channel 8, and is then inhaled into the human body through the air inlet of the respirator 4.

[0074] In some embodiments of the present invention, the medicine tray carrier 6 is provided with a plurality of slots, and the slots are used to detachably arrange the medicine tray 61 .

[0075] In this embodiment, the medicine tray 61 can be fixed by the card slot. When the medicine in the medicine tray is used up or expires, the medicine tray can be removed and replenished with new medicine and then reused.
