Provided is respiratory equipment (1), comprising a main machine (2) and a humidifier (3). The main machine (2) comprises a first gas inlet port (7), a second gas inlet port (23), a first gas outlet port (4), a second gas outlet port (22) and a fan (24). The first gas outlet port (4) is connected to a tube of a mask. The humidifier (3) is connected to the second gas outlet port (22) and the second gas inlet port (23). The main machine (2) further comprises a switching device capable of changing a gas transmission path. The gas transmission path comprises a first transmission path and a second transmission path. The first transmission path is for the gas to enter from the first gas inlet port (7), travel through the fan (24) and then discharge from the first gas outlet port (4). The second path is for the gas to enter from the first gas inlet port (7), travel through the fan (24), the second gas outlet port (22), the humidifier (3) and the second gas inlet port (23), and then discharge from the first gas outlet port (4). The respiratory equipment (1) addresses the problem in the art of inconvenient use and bulkiness of the existing respiratory equipment by disposing a switching device on the main machine (2) to switch the gas transmission path.Linvention concerne un équipement respiratoire (1), comprenant une machine principale (2) et un humidificateur (3).
