Embodiment Construction

[0020] Such as image 3 As shown, in the working state of the pneumatic ground brush of the present invention, the dust-laden airflow 6 enters the brush chamber 1 from the dust suction port 9 and then enters the air duct 7; a drainage passage is set between the brush chamber and the turbine chamber, and the clean airflow 5 is Enter the turbine chamber 2 from the suction port 8, the clean air flow 5 flowing through the turbine chamber 2 enters the brush chamber 1 through the drainage channel, and finally enters the air duct 7, so that when the clean air flow 5 passing through the turbine chamber 2 enters the brush chamber 1 The dust in the dust-laden airflow 6 can be taken away, so that the clean airflow 5 passing through the turbine chamber 2 can be fully utilized. The turbine can be a radial fan, an axial fan or a mixed flow fan. The rotation of the turbine does not need to be driven by the dust-laden airflow 6, but is mainly driven by the clean airflow 5 before entering the ...

Abstract

A pneumatic floor brush (130, 230) and a vacuum cleaner (100, 200). The pneumatic floor brush comprises a shell, a roller brush and a turbine. The shell is provided with a roller brush chamber (1) for accommodating the roller brush and a turbine chamber (2) for accommodating the turbine. The turbine drives the roller brush to rotate. A dust-containing air current (6) enters the roller brush chamber (1) through a dust sucking opening (9) provided on the shell. A clean air current (5) enters the turbine chamber (2) through an air sucking opening (8) provided on the shell. A current guiding channel is provided between the roller brush chamber (1) and the turbine chamber (2). The clean air current (5) that has passed through the turbine chamber (2) enters the roller brush chamber (1) via the current guiding channel. The roller brush and the turbine are not coaxial. The pneumatic floor brush (130, 230) and the vacuum cleaner (100, 200) solve the problem that a turbine is easily blocked or has a weak load capability, and also the clean air current (5) passing through the turbine is fully utilized, thereby enhancing the cleaning efficiency.

Description

technical field [0001] The invention belongs to the technical field of manufacturing small household appliances for daily use, and in particular relates to a pneumatic ground brush and a vacuum cleaner thereof. Background technique [0002] The current vacuum cleaner generally includes a dust bucket, a filter assembly and a motor assembly, the dust bucket, the filter assembly and the motor assembly are located in a housing, and the motor assembly is connected to the dust bucket through the filter assembly. The motor components include the motor and the fan. When the motor is powered on, it drives the fan blades to run at high speed, forming an instant vacuum inside the vacuum cleaner. The air pressure inside the vacuum cleaner is much lower than the outside air pressure. The air flow enters the dust bucket of the vacuum cleaner along the suction nozzle and the air duct, and then is filtered by the filter assembly. The dust remains in the dust collection bag of the filter ass...
