Technical Field

The invention relates to a cleaning device, in particular to a handheld dust collector.

Background

The handheld dust collector is a cleaning product between a common household dust collector and a portable dust collector, and on one hand, the handheld dust collector is suitable for cleaning a smaller space, and on the other hand, various functions of the common household dust collector can be realized by connecting a lengthened dust collection pipe, a floor brush or other accessories. Meanwhile, the existing handheld dust collector is generally provided with a battery unit which can work by being separated from an electric wire.

For example, chinese patent application CN109330477a discloses a handheld vacuum cleaner, comprising: the suction nozzle assembly comprises a housing, a housing cover, a main suction opening arranged on the housing for air intake, a filter arranged in the housing for filtering dust, and at least one suction nozzle accessory. In the embodiment in which the filter is a multi-cone cyclone filter, it can be seen from fig. 1 that the outer periphery of the filter assembly is provided with a metal mesh. Chinese patent application CN109199291a discloses a hand-held vacuum cleaner and a bacteria attaching structure thereof, as can be clearly seen from fig. 2, a metal net is arranged around the periphery of a filter, and a rechargeable battery is arranged below a handle.

In the using process, dust can be adsorbed on the metal net surrounding the periphery of the filter, so that an airflow channel is blocked, and the dust collection efficiency is influenced. Because the metal mesh is fixed on the filter mounting frame in the prior art, the metal mesh is usually difficult to disassemble, and the peripheral space is narrow, so that the cleaning is difficult.

Therefore, the cleaning problem of the metal net is solved, and the use efficiency of the handheld dust collector can be effectively improved.
