Silent oxygen inhalation device with automatic cleaning function

The invention relates to the technical field of medical instruments, in particular to an automatic-cleaning mute oxygen inhalation device which comprises a three-connector humidification bottle and an automatic cleaning device. The mute layer is arranged in the three-connector humidification bottle, oxygen enters air through the mute layer after coming out of water, the situation that large bubbles are generated after the oxygen comes out of the water, and then the sound of bubble breakage is generated is prevented, and therefore mute oxygen inhalation can be achieved, and rest of a patient is facilitated. The three-connector humidifying bottle is connected with the automatic cleaning device through the cleaning connector, the three-connector humidifying bottle is automatically cleaned through the automatic cleaning device, disassembly and reinstallation of the humidifying bottle are reduced, manual cleaning of medical staff is not needed, and the cleaning efficiency is improved.
