[0006] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is:

[0007] A novel compressed air respirator, comprising a backpack, a gas cylinder is arranged in the backpack, a regulating valve is arranged on the top of the gas cylinder, a first connecting pipe is connected to the regulating valve, a connecting assembly is arranged at one end of the first connecting pipe away from the regulating valve, a second connecting pipe is connected to the connecting assembly, and a mask is arranged at one end of the second connecting pipe away from the connecting assembly;

[0008] The connection assembly includes a connection cavity, on which a plurality of quick-connect connectors are threadedly connected, a connection belt is provided on the connection cavity, a plug is provided at one end of the connection belt away from the connection cavity, and the first connection pipe and the second connection pipe are respectively connected to two different quick-connect connectors.

[0009] Furthermore, the plug is inserted into a quick-connect connector that is inserted into the first connecting pipe and the second connecting pipe.

[0010] Furthermore, the backpack is provided with shoulder straps.

[0011] Furthermore, a one-way valve is provided on the second connecting pipe.

[0012] Furthermore, the mask is provided with a connecting rope.

[0013] Furthermore, a protective pad is provided on one side of the backpack close to the shoulder strap.

[0014] The beneficial effects of the utility model are:

[0015] The utility model discloses a novel compressed air respirator. Through the connection assembly, when the gas in the gas cylinder of one worker is used up, the gas cylinder can be quickly connected with the gas cylinder of other workers to ensure gas supply and protect the safety of the workers.
