Although the above oxygen cylinder has solved the problem of oxygen inhalation backflow caused by device offset, due to the liquid storage of oxygen in many hospital oxygen supply systems, the temperature of liquid oxygen after evaporation is low, and the oxygen flows through the oxygen humidification bottle so that the surface temperature of the oxygen humidification bottle is low, so that the moisture in the air condenses on the surface of the humidification bottle to form condensed water; when the air humidity is high, this situation is very common. The condensed water drips and wets the items below it, so the utility model proposes an anti-backflow oxygen device, which is improved based on the traditional anti-backflow oxygen device, and the bottle body constant temperature mechanism is provided to perform constant temperature protection on the humidification bottle to avoid condensed water in the humidification bottle.
