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...

Abstract

The invention discloses an adjustable speed type blowing and absorbing machine. The machine comprises a main machine housing, and a speed regulation mechanism arranged on the main machine housing; an air tube for feeding or discharging air is arranged on the main machine housing; the speed regulation mechanism comprises a speed regulating element which can cover the air tube by a rotating manner, and a speed adjusting button for controlling the rotating position of the speed adjusting element; an adjusting through hole is formed in the main machine housing; one end part of the speed regulating element passes through the adjusting through hole and is fixedly connected with the speed regulating button; the speed regulating mechanism is that the speed regulating button is rotated and the speed regulating element is rotated so as to control the size of an opening of the air tube, and as a result, the blowing force and absorbing force of the machine can be controlled; the speed regulating mechanism used performs speed regulation by a mechanical manner, so that the cost of the machine can be reduced while the speed regulation effect of an electronic speed regulation device is achieved.

Description

technical field [0001] The invention relates to a hand-held operating device, in particular to a portable blower. Background technique [0002] Existing speed-adjustable blowing and aspirating machines are all equipped with electronic speed control devices to adjust the blowing force and suction of the blowing and aspirating machine. Since the cost of the electronic speed regulating device is relatively high, it will inevitably increase the cost of the adjustable-speed blowing machine equipped with the above-mentioned electronic speed regulating device. Contents of the invention [0003] Based on this, it is necessary to provide a low-cost adjustable-speed blower to address the above-mentioned problems. [0004] A speed-adjustable blowing and sucking machine, comprising a main body housing and a speed regulating mechanism arranged on the main body housing, the main body housing is provided with an air duct for air inlet or outlet, and the speed regulating mechanism It in...
