Abstract

The invention relates to the technical field of ventilator accessories, in particular to a turbo blower with an impeller structure for reducing air noise, comprising a driving motor and an external assembly cylinder movably sleeved on the outside of the driving motor. According to the present invention, a turbo fan with an impeller structure with the function of reducing air noise is movably equipped with an external assembly cylinder with an external lateral assembly groove on the outside. The inner assembly cylinder is bolted on the outer side of the outer assembly cylinder through the inner assembly cylinder, and there are external centrifugal blades that are convenient for loading and unloading adjustment. The external centrifugal blades can be retracted and adjusted according to the needs, which greatly facilitates its storage and use; The internal locking nut at the end is threaded to fix and disassemble the movable folding bracket. The operation is simple and convenient, and the assembly firmness is greatly improved; while ensuring assembly stability, it can improve shock absorption and protection performance.

Description

technical field [0001] The invention relates to the technical field of ventilator accessories, in particular to a turbo blower with an impeller structure for reducing air noise. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] Ventilators are divided into controlled mechanical ventilation (CMV) and assisted mechanical ventilation (AMV) according to the type of use, and are powered by an internal centrifugal fan, which is mainly composed of a volute, an impe...
