In hospital clinics, many patients often require oxygen therapy. While continuously dry oxygen passing through the patient's respiratory tract can cause damage to the respiratory tract. To avoid such damage, the dry oxygen needs to be humidified. In order to achieve the purpose of oxygen humidification, an oxygen humidification bottle is added between an oxygen supply center and a nasal oxygen tube (or an oxygen mask) so that continuously dry oxygen can be humidified after passing through humidification liquid in the humidification bottle and then enters a patient body through the nasal oxygen tube (or the oxygen mask). Thus, damage to the patient's respiratory tract by the continuously dry oxygen is avoided. However, the existing oxygen humidification bottle generally contains water in a bottle body, and then the bottle cap is connected with an aeration pipe which is introduced into water, so that moisture is carried in the process of oxygen contacting with water, thereby achieving the purpose of humidifying oxygen, but the oxygen comes out from the aeration pipe and upwards comes out from the water, so that larger noise (45-65 decibels) can be generated, when the oxygen flow is larger, the noise is more prominent, and the rest of patients with poor sleep quality and fear of noise is influenced.
