Hand-push type leaf suction machine with toppling automatic power-off function
The invention discloses a hand-push type leaf suction machine with a toppling automatic power-off function. The fan blade height of a fan is located at the middle portion of the height direction of adust collecting box, the lower surface of the dust collecting box is close to the ground, the lower end of the air inlet channel is close to the ground, the upper end of the air outlet channel is connected to the top of the side face of the dust collecting box, the overall length of the air inlet channel and the air outlet channel is small, and the wind strength in the air channel can be improved.Meanwhile, as the lower end of the air inlet channel is close to the ground, if a motor in the air channel is touched, the machine shell needs to incline backwards to enable the two supporting legs and the pushing handle to be supported on the ground, the wheel shaft slides to the bottom of the movable groove under the action of gravity, and the microswitch is in a power-off state at the moment;or the machine shell needs to topple towards two sides, the acting force on the wheel shaft disappears after the machine shell topples, the microswitch is also in a power-off state at the moment, andfinally the toppling automatic power-off function is achieved; and meanwhile, when the whole hand-push type leaf suction machine is lifted up, the microswitch is also in a power-off state.
本发明公开了一种具有倾倒自动断电功能的手推式吸叶机，风机的风叶高度处于集尘箱高度方向的中部，集尘箱的下表面靠近地面，进风通道的下端贴近地面，出风通道的上端连接在集尘箱的侧面顶部，此时进风通道和出风通道的整体长度较短，有利于提高风道内的风力强度；同时因进风通道的下端贴近地面，若有触碰到风道内的电机，需机壳后倾使得两个支撑腿与推手支撑在地面上时，此时因轮轴在重力作用下滑落到活动槽底部，此时微动开关处于断电状态；或需使得机壳朝向两侧倾倒，机壳倾倒后对轮轴的作用力消失，此时微动开关也处于断电状态，最终实现倾倒自动断电功能；同时在手推式吸叶机整体抬起来时，微动开关也处于断电状态。
