Description

Technical Field

[0001] This utility model relates to the technical field of a dual-cylinder parallel compressed air breathing apparatus, and in particular to a dual-cylinder parallel compressed air breathing apparatus. Background Technology

[0002] Air respirators are widely used in fire protection, chemical industry, shipbuilding, petroleum, metallurgy, warehouses, laboratories, mines and other sectors to enable firefighters or rescue personnel to safely and effectively carry out firefighting, disaster relief and rescue work in various environments such as dense smoke, toxic gas, steam or oxygen deficiency.

[0003] Among existing dual-cylinder parallel compressed air breathing apparatuses, such as the one disclosed in utility model patent application number 201820367429.8, when the corresponding working time is short, the amount of compressed air used in the cylinder is small. Carrying one cylinder can reduce the weight of the object carried by the operator, making the work more labor-saving and convenient. When more compressed air is used, carrying two cylinders allows the work to be completed in one go, and it is less likely to cause inconvenience due to insufficient air supply. Therefore, it makes rescue or first aid work more convenient.

[0004] However, in the use of a dual-cylinder parallel compressed air breathing apparatus, the use of gas from both cylinders to mix the gas in the two cylinders will result in uneven mixing of the gas in the two cylinders, and it is not easy to replace the gas after a single cylinder is used up. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a dual-cylinder parallel compressed air breathing apparatus that, by setting a connecting mechanism and a mixing mechanism, can uniformly mix the gases in the two cylinders during use, and can be easily disassembled and replaced.

[0006] This utility model discloses a parallel compressed air breathing apparatus with two gas cylinders, including a fixing mechanism; it also includes two sets of gas storage mechanisms, a mounting mechanism, a connecting mechanism, and a mixing mechanism. The two sets of gas storage mechanisms are installed on the fixing mechanism, the mounting mechanism is installed at the front end of the fixing mechanism, the connecting mechanism is installed on the mounting mechanism, and the mixing mechanism is installed at the lower end of the connecting mechanism.

[0007] The fixing mechanism secures the gas, the gas storage mechanism stores gas, the erection mechanism erects the gas, the connecting mechanism connects the gas, and the mixing mechanism mixes the gas. The fixing mechanism secures the gas storage mechanism, the gas storage mechanism supplies gas, the erection mechanism secures the connecting mechanism, the connecting mechanism connects the gas storage mechanism, and the mixing mechanism mixes the gas. This allows the gas in both cylinders to be evenly mixed during use of the dual-cylinder parallel compressed air breathing apparatus, and it can be easily disassembled and replaced.

[0008] Preferably, the fixing mechanism includes a base plate, four sets of fixing brackets and four sets of rubber pads. The four sets of fixing brackets are installed at the front end of the base plate, and each set of fixing brackets is equipped with a set of rubber pads. The fixing brackets fix the gas storage mechanism, and the rubber pads prevent the gas storage mechanism from slipping.

[0009] Preferably, the gas storage mechanism includes a gas tank, an exhaust port, and a valve. The gas tank is fixed on a mounting frame, the exhaust port is installed at the lower end of the gas tank, and the valve is installed on the exhaust port. The gas is stored through the gas tank, discharged through the exhaust port, and opened and closed through the valve.

[0010] Preferably, the erection mechanism includes three sets of brackets, three sets of fixing plates, and six sets of nuts. The three sets of brackets are installed at the front end of the base plate, and each set of brackets is fixed with a set of fixing plates by two sets of nuts. The fixing plates fix the connecting mechanism and the mixing mechanism by threaded engagement between the nuts and the brackets.

[0011] Preferably, the connecting mechanism includes a connecting pipe, two sets of valves, and two sets of threaded sleeves. The connecting pipe is mounted on two sets of supports, the two sets of valves are mounted on the connecting pipe, and the two sets of threaded sleeves are mounted on the connecting pipe by threads. The connecting pipe connects the gas in the gas tank, the valves unclog and lock the gas, and the threaded sleeves are threadedly engaged with the exhaust port to seal the exhaust port and the connecting pipe.

[0012] Preferably, the mixing mechanism includes a mixing chamber and a torsion blade. The mixing chamber is installed at the lower end of the pipe, and the torsion blade is rotatably installed inside the mixing chamber. The gas is mixed by the torsion blade rotating as airflow passes through the mixing chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the gas storage mechanism is fixed by the fixing mechanism, the gas storage mechanism is supplied with gas, the connecting mechanism is fixed by the mounting mechanism, the gas storage mechanism is connected by the connecting mechanism, and the gas is mixed by the mixing mechanism. Thus, during the use of the dual-cylinder parallel compressed air breathing apparatus, the gas in the two cylinders can be mixed evenly, and it can be easily disassembled and replaced.
