After blowing, just pull it out, making the installation and disassembly between the flexible airbag and the gas output joint more convenient.

[0008] Preferably, a ring-shaped connecting piece and a first annular groove are arranged on the gas output joint, a second annular groove matched with the ring-shaped connecting piece is arranged on the flexible airbag, and a ring-shaped protrusion matched with the first annular groove is arranged in the second annular groove.

[0009] Through the above technical solution, the airtightness of the connection between the flexible airbag and the gas output joint is better, improving the air blowing effect of the airbag.

[0010] Preferably, a conical connecting piece is provided on the gas output joint, and a conical groove matching with the conical connecting piece is provided on the flexible airbag.

[0011] Through the above technical solution, through the cooperation of the conical connecting piece and the conical groove, the airtightness of the connection between the flexible airbag and the gas output joint is better, improving the air blowing effect of the airbag.

[0012] Preferably, a pressure relief hole is provided on the gas output joint, and a pressure relief rubber ring is installed at the pressure relief hole of the gas output joint.

[0013] Through the above technical solution, when the oxygen input pressure of the medical oxygen humidifier is too high, oxygen can be discharged through the pressure relief hole to ensure the stability of the oxygen supply pressure of the medical oxygen humidifier.

[0014] Another theme is a medical oxygen humidifier, including the above-mentioned medical oxygen humidifier bottle cap and liquid storage bottle. An aerator is installed on the bottle cap body, and the aerator is communicated with the gas input joint.

[0015] Through the above technical solution, humidification of medical oxygen can be realized.

[0016] Beneficial effects: When installing the medical oxygen humidifier, the liquid that enters the gas output joint during transportation and storage can be blown into the liquid storage bottle through the airbag. Then, after removing the airbag, the air outlet pipe is connected to the gas output joint. Prevent the liquid in the gas output joint from entering the gas pipeline and causing discomfort to the patient. Description of the Drawings
