Description

Mute humidifying cup and humidifying method thereof Technical Field The invention relates to the field of mute humidifying cups, in particular to a mute humidifying cup and a humidifying method thereof. Background The medical oxygenerator is used as key equipment for clinical treatment and home oxygen therapy, and the output dry oxygen can be inhaled by patients after humidification treatment, so that the damage of respiratory tract mucous membrane due to dryness is avoided, and the oxygen inhalation comfort level and the treatment effect are ensured. Therefore, the humidifying cup is used as a core matching component of the oxygenerator, and the humidifying performance, the use experience and the safety of the humidifying cup directly influence the quality of oxygen therapy. The humidifying cup of the traditional medical oxygenerator generally adopts a bubbling humidifying principle, namely dry oxygen is directly led into the water storage through a flow guide pipe, and gas-liquid contact humidifying is realized by utilizing bubbles formed when the oxygen passes through a water layer. However, the technical scheme has the inherent and difficult defects that firstly, bubbles can generate continuous gurgling sound when the water surface breaks, the patient rest is seriously disturbed in night or quiet medical environment, the use experience is obviously reduced, secondly, the humidifying efficiency is influenced by multiple factors such as water depth, bubble size, air flow speed and the like, the constant humidification efficiency is difficult to maintain, the fluctuation of the humidity of the inhaled air of the patient is large, the treatment effect is possibly influenced, thirdly, a guide pipe immersed in water is easy to accumulate scale and a microbial film, the cleaning difficulty is high, the blockage is easily caused after long-term use, the maintenance process is complicated, fourthly, the water body is easily splashed due to direct impact of air flow, the risk of bacteria diffusing along with the air flow is increased, and potential health hazards exist.
