Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting self-rescue equipment, in particular to a chemical oxygen fire-fighting self-rescue respirator with a cooling layer and capable of generating oxygen efficiently and preventing gas stagnation. Background Art

[0002] Chemical oxygen fire-fighting self-rescue respirator is a personal respiratory protection device made using the principle of chemical oxygen generation. It is widely used in fire or other disaster environments, such as hotels, entertainment, office places, mines, military equipment, etc.

[0003] For example, the patent number CN203724657U discloses a chemical oxygen firefighting self-rescue respirator with a cooling layer and high efficiency oxygen generation and anti-gas stagnation, including: a mask 1 for wearing, a breathing mask 2 located in the mask, an oxygen tank 3, an air duct 5, and an air bag 6. The breathing mask 2 is located on the mask 1 and connected to the opening of the air bag 6. The connection between the breathing mask 2 and the opening of the air bag 6 has two one-way valves-an exhalation one-way valve and an inhalation one-way valve; the oxygen tank 3 is located inside the air bag 6, and the air inlet at the top is connected to the breathing mask 2 through the exhalation one-way valve. A closed cavity is formed between the inner wall 12 of the oxygen tank and the outer shell 11 of the oxygen tank. The cooling layer 7 is formed in the closed cavity by filling the coolant. At the same time, a coolant filling port 10 for filling the coolant is opened on the outer shell 11 of the oxygen tank.

[0004] In the above scheme, a cooling layer is arranged outside the oxygen generating tank to dissipate heat inside the oxygen generating tank through the cooling layer. However, in actual use, it is found that the heat dissipation effect of the cooling layer alone is poor, and the heat inside the oxygen generating tank cannot be quickly reduced, so that it takes a long time for the breathing temperature to drop to between 35°C and 45°C. Therefore, a chemical oxygen firefighting self-rescue respirator with a cooling layer and high efficiency oxygen generation and anti-gas stagnation is proposed. Utility Model Content

[0005] The utility model aims to solve the problems raised by the background technology and proposes a chemical oxygen fire fighting self-rescue breathing apparatus with a cooling layer and the function of generating oxygen efficiently and preventing gas stagnation.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A chemical oxygen firefighting self-rescue respirator with high efficiency of oxygen generation and anti-gas stagnation having a cooling layer, comprising a breathing mask, an oxygen generating tank, an air bag and a water bag, wherein the breathing mask is arranged on the top of the air bag, the oxygen generating tank is arranged inside the air bag, and the oxygen generating tank is connected to the breathing mask through an air guide tube, two diverter plates are arranged inside the oxygen generating tank, and an oxygen generating agent is arranged between the two diverter plates, an annular cooling plate is fixedly arranged on the outer side wall of the oxygen generating tank, and the annular cooling plate adopts a hollow structure, the water bag is arranged at the bottom of the air bag, water pipes are fixedly arranged on both sides of the bottom of the annular cooling plate, one end of the two water pipes away from the annular cooling plate is connected to the water bag, and the pipe walls of the two water pipes are respectively provided with a first liquid one-way valve and a second liquid one-way valve.

[0008] Preferably, a plurality of evenly distributed heat-conducting partition plates are fixedly provided between the two diverter plates, and the oxygen generating agent is located between two adjacent heat-conducting partition plates.

[0009] Preferably, a plurality of evenly distributed spoiler blocks are fixedly provided on the inner side wall of the annular cooling plate, and the spoiler blocks are arranged in a staggered distribution.

[0010] Preferably, the first liquid one-way valve is a water outlet one-way valve, and the second liquid one-way valve is a water return one-way valve.

[0011] Preferably, both the air duct and the water pipe are soft pipes.

[0012] Preferably, the heat-conducting partition plate and the annular cooling plate are both made of aluminum alloy plates.

[0013] Compared with the prior art, the utility model provides a chemical oxygen fire fighting self-rescue respirator with a cooling layer for efficient oxygen generation and anti-gas stagnation, which has the following beneficial effects:

[0014] The highly efficient oxygen-generating and anti-gas-stagnating chemical oxygen fire-fighting self-rescue breathing apparatus with a cooling layer is provided with a water bag, an annular cooling plate, a water pipe, a first liquid one-way valve and a second liquid one-way valve. When it is necessary to quickly cool down the interior of the oxygen generating tank, the water bag is pressed by hand so that the cooling water in the water bag is discharged into the interior of one of the water pipes and then discharged into the interior of the annular cooling plate. The cooling water can quickly reduce the surface temperature of the annular cooling plate, thereby quickly reducing the temperature inside the oxygen generating tank, so that the temperature of the oxygen is quickly reduced to between 35°C and 45°C. The water in the annular cooling plate is then recovered in the water bag through another water pipe. Since the amount of water in the water bag is sufficient and the temperature of the recovered water is relatively high, it can be naturally cooled in the water bag.

[0015] The parts not involved in the device are the same as the prior art or can be implemented by the prior art. The utility model has a water cooling structure, which can quickly reduce the temperature inside the oxygen tank, so that the temperature of oxygen is quickly reduced to between 35°C and 45°C, thereby improving the oxygen production efficiency. At the same time, the oxygen tank is arranged inside the airbag, which can effectively prevent the airbag from wrinkling or sticking, eliminate air stagnation, and ensure smooth airflow.

The first liquid one-way valve 10 is a water outlet one-way valve, and the second liquid one-way valve 11 is a water return one-way valve. When it is necessary to quickly cool down the interior of the oxygen generating tank 2, the water bag 4 is pressed by hand, so that the cooling water inside the water bag 4 is discharged into the interior of one of the water pipes 9, and then discharged into the interior of the annular cooling plate 8.
