[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation function, have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation. They occupy a very important position in the field of modern medicine. Ventilators are a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives.

[0003] Home ventilators are used to treat or assist lung ventilation, and assist in the treatment of nighttime respiratory distress syndrome. Because the ventilator relies on the rotation of the impeller to drive the airflow to generate pressure flow, and the airflow will generate noise, which will seriously disturb the patient's rest output.

[0006] Preferably, the housing assembly comprises an upper shell, a lower shell and a plastic cover plate. The upper shell and the lower shell are detachably mounted. A plastic cover plate is mounted on the bottom of the lower shell, and the plastic cover plate is used to prevent water from entering the lower shell.

[0007] Preferably, the rotating blade assembly comprises a rotating blade upper cover and a rotating blade lower cover, and the rotating blade upper cover and the rotating blade lower cover are ultrasonically welded.

[0008] Preferably, the rotating shaft assembly includes a combined ball copper part, an axial magnet assembly and a silicon steel sheet wire frame assembly. The combined ball copper part is installed on the lower shell. The combined ball copper part passes through the lower shell, the rotating blade lower cover and the rotating blade upper cover in sequence. The axial magnet assembly is installed on the combined ball copper part, and the silicon steel sheet wire frame assembly is installed at the bottom of the lower shell.

[0009] The beneficial effects of the utility model are as follows: the air entering through the air inlet of the shell component drives the rotating blade component through the rotating shaft component to make the wind evenly discharged from the air outlet of the shell component, thereby reducing noise and efficiently utilizing the airflow.
