HAND-PUSH-TYPE LEAF VACUUM WITH FUNCTION OF AUTOMATICALLY POWERING OFF WHEN TOPPLED

摘要

Disclosed in the present invention is a hand-push-type leaf vacuum with the function of automatically powering off when toppled. Blades of a fan are as high as the middle portion of a dirt collection tank in the height direction, the lower surface of the dirt collection tank is close to the ground, the lower end of an air intake channel is close to the ground, the upper end of an air output channel is connected to the top portion of a side face of the dirt collection tank, and in this case, the overall length of the air intake channel and the air output channel is short, which is conducive to the improvement of the wind strength in the air channel; in addition, due to the fact that the lower end of the air intake channel is close to the ground, if an electric motor in the air channel is touched, and a machine shell needs to incline backwards to enable two supporting legs and a pushing handle to be supported on the ground, then at this moment, because a wheel shaft slides to the bottom portion of a movement slot under the action of gravity, at this moment, a microswitch is in a power-off state; or the machine shell needs to be toppled towards two sides, the acting force on the wheel shaft disappears after the machine shell is toppled, and at this moment, the microswitch is also in a power-off state, finally achieving the function of automatic powering off during toppling is achieved; and in addition, when the whole hand-push-type leaf vacuum machine is lifted up, the microswitch is also in the power-off state.
