The invention provides a water supply system of an air respirator. The water supply system comprises a water bag, an external connection tube, an air supply valve internal tube, a mask tube and a mouthpiece. The water bag is connected with the external connection tube through a nut in a screwed manner. The external connection tube is connected with the air supply valve tube through a rapid connector. The air supply valve internal tube and the mask tube achieve insertion connection in a manner that an air supply valve is inserted into a mask. The mask tube is connected with the mouthpiece. The air supply valve internal tube is provided with a water supply channel and an air supply channel. The water supply system of the air respirator can effectively help a rescue worker solve the physical output problem in the rescuing process, the components of the water supply system are convenient to mount and demount, and it is guaranteed that the rescuing work is carried out efficiently.
Description
technical field [0001] The invention relates to a fire fighting equipment, in particular to a water supply system for an air respirator. Background technique [0002] Firefighting, emergency rescue and rescue personnel are faced with a severe environment during the battle, with high mental pressure and high labor intensity, resulting in a large amount of water and physical exertion, which reduces their combat capabilities. The air respirators currently on the market can only provide sufficient oxygen for rescuers, but cannot provide enough water for rescuers, which greatly affects rescue efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention provides a new type of water supply system for air respirators. The water supply system is effectively combined with the air respirator, which can supply both air and water, effectively ensure the combat ability of rescuers, and improve rescue efficiency. [0004] A water supply syst...
