[0034] Please refer to Figures 1 to 2The first embodiment of the present application provides a fan 10 capable of stabilizing flow and reducing noise, which is used in respiratory therapy equipment. First, air enters the air inlet chamber 13 through the air inlet hole 131 of the shell body 11. In the air inlet chamber 13, the airflow velocity is initially reduced, reducing the impact force of the airflow, thereby avoiding sudden pressure changes that generate noise and vibration. Next, the gas flows through the slow-flow baffle 132. The teardrop-shaped cross-section of the slow-flow baffle 132 can provide a smooth airflow transition, further slowing down the airflow velocity and reducing noise. It not only helps the airflow flow evenly, but also reduces turbulence caused by sudden airflow. Subsequently, the buffered airflow enters the airflow rising channel 133 and gradually flows upward to the main unit area 1111. In the main unit area 1111, the worm turbine 15 pressurizes the gas through the worm turbine blades. The worm turbine outlet of the worm turbine 15 is connected to the stable flow and noise reduction area 1112 through the buffer sleeve 152, so that the pressurized gas can be discharged smoothly into the stable flow and noise reduction area 1112, further reducing noise and vibration. In the flow stabilization and noise reduction area 1112, the detachable flow stabilization and noise reduction part 1113 is provided with a number of flow stabilization and noise reduction through holes 1114. When the airflow passes through the flow stabilization and noise reduction through holes 1114, it is redirected and its speed is reduced to achieve a better noise reduction effect. The hexagonal shape of the flow stabilization and noise reduction through holes 1114 and the setting of the arc-shaped transition section 1115 can effectively reduce the turbulence of the airflow and improve the stability of the airflow. Finally, the airflow flows out through the outlet pipe 1118 for use in respiratory therapy equipment. This not only optimizes the flow path of the airflow, but also effectively reduces the noise and vibration during the operation of the blower 10 capable of flow stabilization and noise reduction, thereby improving the comfort of patients when receiving respiratory therapy.

The first plug-in plate groove 1116 and the second plug-in plate groove 1117 are both used to fix the flow stabilizing noise reduction component 1113, thereby ensuring the stability of the flow stabilizing noise reduction component 1113 during use, preventing the flow stabilizing noise reduction component 1113 from loosening or falling off due to vibration, thereby reducing the noise or vibration generated by the airflow.
