Handheld vacuum cleaner

Abstract

The present disclosure discloses a handheld vacuum cleaner, including a housing, a dust collecting mechanism, and a filtering mechanism. The housing includes an installation part, an installation groove is formed in the installation part, and the installation groove is used for accommodating the filtering mechanism. The filtering mechanism is detachably installed in the installation groove, and disassembly and installation of the filtering mechanism do not cause the dust collecting mechanism and the housing to be reassembled. By forming the installation groove in the housing, the installation groove can directly clamp and fix the filtering mechanism. The installation or disassembly of the filtering mechanism can be completed by directly inserting the filtering mechanism into the installation groove or directly pulling the filtering mechanism out of the installation groove, without causing the dust collecting mechanism and the housing to be reassembled. The disassembly and installation of the filtering mechanism are very convenient.
