Detailed ways

The technical scheme of the present utility model is described below in conjunction with accompanying drawing and embodiment.

As shown in Figure 1, a handheld vacuum cleaner described in the utility model includes a body 1, a suction nozzle 2 and an exhaust hole 3 located on the body 1, and an airflow generator 4 located in the body 1, the airflow The generator 4 communicates between the suction nozzle 2 and the exhaust hole 3 through an internal air passage; a separation device 5 is provided between the suction nozzle 2 and the air flow generator 4, and the separation device 5 is located at the suction nozzle. 2; the body 1 is provided with a handle 7, and the handle 7 is provided with a switch assembly 8 for controlling the airflow generator 4; the airflow generator 4 is electrically connected to a power supply 6, and the power supply 6 is installed inside the handle 7. The hand-held vacuum cleaner of the present utility model, by reorganizing and arranging the parts of the vacuum cleaner, makes the arrangement of the whole machine compact, and at the same time installs the power supply 6 inside the handle 7, so that the space distance between the power supply 6 and the airflow generator 4 becomes smaller, The power supply 6 and the airflow generator 4 do not need to be electrically connected through a long line, which can effectively reduce energy consumption loss, prolong the use time of the vacuum cleaner after a single charge, and prolong the service life of the power supply 6 at the same time.

Specifically, the handle 7 is located below the airflow generator 4 and immediately adjacent to the airflow generator 4, so that the power supply 6 and the airflow generator 4 can be directly connected, and the electrical circuit between the two is very short. Further reduce the energy loss on the line.

Simultaneously, the horizontal height of described airflow generator 4 is higher than the horizontal height of described separating device 5, makes the airflow that airflow generator 4 produces can enter from suction nozzle 2 smoothly, passes through airflow generator 4 again after separating device 5 Exhausted from the exhaust hole 3, the entire airflow is very smooth when flowing, which improves the air performance of the whole machine.

The airflow generator 4 includes a motor and fan blades. The fan blades are installed on the output shaft of the motor. The high-speed rotation of the motor drives the power fan blades to rotate at high speed, which can generate high-speed airflow and improve the dust collection ability of the vacuum cleaner.
