Embodiment Construction
[0037] Please refer to Figure 1 to Figure 5 , this embodiment discloses a speed-adjustable blower 100 , including a main body housing 110 , a blowing and absorbing member 120 detachably connected to the main body housing 110 , and a speed regulating mechanism 130 arranged on the main body housing 110 . Through the mechanical speed regulation mode of the speed regulating mechanism 130, the air volume blown out and inhaled by the blower and suction machine can be controlled.
[0038] The main body casing 110 includes a main body 111 with a driving fan (not shown in the figure) inside and an air duct 112 for air inlet or outlet. When the fan is driven to rotate, the air in the surrounding area will generate a vortex movement and a circulating airflow will be generated in the air duct 112 , so that the air blower 100 can blow or suck air. The speed regulating mechanism 130 is arranged in the above-mentioned air duct 112 . In other embodiments, the speed regulating mechanism 130...
