In order to improve dust removal efficiency, hand-held vacuum cleaners generally include a body provided with a handle, a cyclone gas separation device mounted on the body, a telescopic tube connected to the cyclone dust separation device, a battery mounted on the body, a motor, and a fan. Wind filter unit. In the prior art, the layout of these components is often disclosed in the Chinese invention patent CN101489454B, wherein the motor and the battery are respectively disposed at the upper end and the lower end of the handle, and the air outlet filter device is located at the rear of the motor, and the air outlet filter device is limited. The shape has a small cross-sectional area, the filtering effect is not high, and the number of replacements is frequent. At the same time, since the airflow is discharged from the motor and discharged to the outside through the air filtering device, the air outlet duct is not smooth and short, and the noise reduction effect is further improved. Not obvious, and the motor and battery are far apart, and the arrangement of the wires is more complicated; the use of the center of gravity is more difficult to use; the handle angle does not conform to the usage habits.
