The invention discloses a handheld
vacuum cleaner host, which comprises a dust cup, an air duct connecting
pipe, a motor and a
handle, wherein one end of the air duct connecting
pipe is connected to a floor
brush and the other end of the air duct connecting
pipe is connected to an air inlet of the dust cup, and an air outlet of the dust cup is connected to an exhaust duct of the motor; the motor is arranged on one side of the air outlet of the air duct connecting pipe; an included angle between the motor and the center line of the dust cup is 0-69 degrees; the
handle is arranged on one side of the dust cup; the
handle and the dust cup are detachably connected; and through
suction force generated from negative pressure formed due to rotation of the motor, dust is sucked by the floor
brush and enters into the dust cup along the air duct connecting pipe, the dust is separated and filtered by virtue of a
cyclone in the dust cup, the dust is accumulated in the dust cup, and clean air, obtained through
filtration, is discharged from the motor. According to the
vacuum cleaner host disclosed by the invention, the dust cup is arranged at the upper part of the air duct connecting pipe in a
transverse mode, so that the entire host is compact in structure; optimally, the included angle between the motor and the center line of the dust cup is 0-30 degrees, so that smooth operation of an air duct is guaranteed and the size of the host is diminished.
