| Zusammenfassung: | The utility model relates to a continuous positive pressure ventilation therapy machine and an air inlet structure of the continuous positive pressure ventilation therapy machine. The continuous positive pressure ventilation therapy machine and the air inlet structure of the continuous positive pressure ventilation therapy machine overcome the defects that a usable area of filtering cotton in an existing continuous positive pressure ventilation therapy machine is small and the whole filtering cotton can not be used completely. The air inlet structure comprises an air inlet seat provided with a through hole and multiple first supporting parts, a cover body and an air filtering part, wherein the cover body can cover the air inlet seat, a cavity is formed by the cover body and the air inlet seat, the cover body is provided with an air inlet hole and/or an air inlet groove, and the air filtering part is arranged in the cavity, abuts between the multiple first supporting parts and the cover body and is not attache |
