[0002] A hand-push vacuum cleaner is a cleaning device suitable for cleaning floors, carpets and other surfaces, and is commonly found in commercial environments and industrial places. When a hand-push vacuum cleaner moves on the surface to be cleaned and performs vacuuming operations, a dust-laden airflow is usually provided by a suction motor to enter a negative pressure airflow in a dust collecting box from a suction port, and the dust collecting unit filters and collects dust particles in the dust-laden airflow, and the filtered air is discharged into the external environment. Since a hand-push vacuum cleaner usually uses a wire and a plug to connect to the mains, and supplies the power of the mains to the suction motor. Therefore, the range of movement of the hand-push vacuum cleaner is often limited by the length of the wire, which makes it particularly inconvenient to operate.

[0046] When the user pushes the hand-push floor cleaning device 100 to move on the surface to be cleaned and performs cleaning operations, since the hand-push floor cleaning device 100 moves with the power supply 40 in tow, in order to prevent the battery 43 from accidentally falling out of the battery compartment 414 due to the unevenness of the surface to be cleaned, thereby causing the hand-push floor cleaning device to be powered off, the battery compartment 414 extends upward at an angle relative to the horizontal plane, so that after the battery 43 is loaded into the battery compartment 414, the battery 43 can always maintain conductive contact between the conductive portion 415 of the battery 43 and the conductive matching portion of the battery compartment 414 under the action of gravity.

[0047] Furthermore, the power box 41 is also provided with a shielding portion 416 spanning across the multiple battery compartments 414 , and the shielding portion 416 is used to shield and protect the batteries 43 in the multiple battery compartments 414 .
