Problems solved by technology

[0003] Among them, the impeller, the core component of the fan, has a great influence on the output airflow, pressure and noise. When the impeller of the prior art is working, the airflow will flow to the low-pressure area in the volute after being separated from the blade under the action of centrifugal force, and there will be Collision and mixing will lead to confusion in the output airflow and pressure, as well as turbulence and noise, which will affect the performance and use experience of the fan

Embodiment Construction

[0031] In order to describe the technical content and structural features of the present invention in detail, further description will be given below in conjunction with the implementation and accompanying drawings.

[0032] Such as Figure 1 to Figure 7 As shown, the invention discloses a ventilator (not shown in the figure). The ventilator includes a blower 10 . Since the structure of the ventilator is well known to those skilled in the art, the rest of the structures included in the ventilator will not be repeated here.

[0033] Wherein, the fan 10 includes a volute 11 , a driver 12 and an impeller 13 . The impeller 13 is installed in the volute 11, the driver 12 is installed in the volute 11, the impeller 13 is installed in the output end of the driver 12, the driver 12 drives the impeller 13 to rotate, and the rotating impeller 13 compresses the air to generate air flow. For example, the driver 12 is a motor, but not limited thereto. The impeller 13 includes a disc-sh...

Abstract

The impeller comprises a disc-shaped main body and a plurality of blades fixed to the main body, a blade arrangement area and a pressure maintaining area are sequentially formed on the upper surface of the main body outwards in the radial direction of the main body, the pressure maintaining area is arranged around the blade arrangement area, the blades are arranged on the blade arrangement area, and a plurality of notches are formed in the circumferential side of the main body. The impeller has the advantage that output air pressure and air flow are stable. In addition, the invention further discloses a fan and a breathing machine.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an impeller, a fan and a ventilator. Background technique [0002] The blower is the core component of the home ventilator. Its function is to rely on the input mechanical energy to increase the gas pressure and deliver the gas to improve the patient's oxygenation and ventilation, reduce the work of breathing, support breathing and circulatory functions, and treat respiratory failure. . [0003] Among them, the impeller, the core component of the fan, has a great influence on the output airflow, pressure and noise. When the impeller of the prior art is working, the airflow will flow to the low-pressure area in the volute after being separated from the blade under the action of centrifugal force, and there will be Collision and mixing will lead to confusion in the output airflow and pressure, as well as turbulence and noise, which will affect the performance and use experience of th...
