A main device thereof is a handheld vacuum cleaner, and a push rod is a hollow rod. The rod handheld two-in-one split-type vacuum cleaner is provided with an independent dust-air separation and dust storage device on the push rod located above a floor brush and below the handheld vacuum cleaner. The dust-air separation and dust storage device can be independently removed to dump the dust. The main device, the push rod and the floor brush of the rod handheld two-in-one split-type vacuum cleaner can by split or assembled as different usage modes. The rod handheld two-in-one split-type vacuum cleaner can operate as a floor mopping vacuum cleaner, a handheld vacuum cleaner and a handheld vacuum cleaner with a long connecting tube.

Abstract: A handheld dust collector, a spiral two-stage tornado dust-air separation structure and a primary dust barrel are disposed in the body of the handheld dust collector. The spiral two-stage tornado dust-air separation structure includes a first-stage cyclone barrel, a second-stage cyclone barrel, a cyclone cover, and a spiral dust-air separation apparatus disposed at the upper end of the second-stage cyclone barrel. The first-stage cyclone barrel and the cyclone cover perform first-stage dust-air separation on primary dust-air entering the spiral two-stage tornado dust-air separation structure, and second-stage dust-air after previous separation enters the second-stage cyclone barrel for second-stage dust-air separation. The dust collector is small in the number of components, simple in assembling procedure, and high in comprehensive performance of a complete machine.

Abstract: A motor noise reduction structure for a dust collector, and the dust collector are provided. The noise reduction structure includes: a mounting portion, used for mounting a motor on a dust collector; and elastic components, used for applying tension to the motor. One end of each elastic component is connected to the mounting portion, and the other end of the elastic component is connected to the motor. The tension can counteract the gravity of the motor. The number of the elastic components is at least two. The elastic components are uniformly distributed at the circumference of the motor. An included angle of 10 to 85 degrees is formed between the direction of the tension and the horizontal plane. By means of the motor noise reduction structure for a dust collector and the dust collector, a good motor noise reduction effect can be obtained.

Abstract: A rotor applicable to a vacuum cleaner motor includes a rotating shaft, a rotor magnetic steel, a load blade, two bearings between the rotor magnetic steel and the load blade, and a pre-tightening spring for providing precompressions to the bearings at two sides. The bearings are arranged between the load blade and the rotor magnetic steel, so that the motor structure is simplified, the overall size of the motor is reduced, and the machining and manufacturing of the vacuum cleaner motor are facilitated. As the pre-tightening spring is arranged between the two bearings, the bearings are close to the load blade as much as possible under the effect of pre-tightening force.

Abstract: A two-stage dust-air separation structure includes a cyclone separator and a spiral dust-air separation device. A first stage separation of dust from air is realized by a cyclone housing, and by arranging a second-stage cyclone barrel 5 inside the cyclone housing and arranging the spiral dust-air separation device at a barrel opening of the second-stage cyclone barrel, the dusty air, after going through the first stage separation, is guided by the spiral dust-air separation device to form, on an inner wall of the second-stage cyclone barrel, an airflow rotating towards the barrel bottom, and the dust in the airflow is driven by a centrifugal force to rotate downwardly to the barrel bottom and be collected in a second-stage dust collecting space, and the air in the rotating airflow is extracted by the negative pressure, thereby realizing a second stage separation of dust from air.
