This invention relates to the field of oxygen humidification technology, specifically to a medical oxygen cylinder nebulizer humidification device, comprising a water tank with a removable sealing cap at the top and a removable mixing hood at the top of the sealing cap. The operation of a driving component drives a cleaning component, which in turn drives a linkage component, causing the linkage component to rotate. The linkage component's internal components drive a mixing component, which in turn drives the mixing component's internal components, causing them to rotate around the arc-shaped structure of the mixing hood and rotate on their own axis. This agitates the nebulized medication and oxygen inside the mixing hood, ensuring thorough mixing of the oxygen and medication. This improves the uniformity of the nebulized medication content in the oxygen, resulting in uniform oxygen humidity and reducing the possibility of uneven mixing when the nebulized medication is mixed with oxygen. This ensures consistent oxygen humidification delivered to the patient's respiratory tract, improving the therapeutic effect on the patient.
