Dust collector brush head structure with internal ventilation baffle plate

Abstract

The invention discloses a dust collector brush head structure with an internal ventilation baffle plate. The dust collector brush head structure comprises an upper suction nozzle cover, a suction nozzle base plate, rolling brushes and the internal baffle plate, the upper suction nozzle cover and the suction nozzle base plate form the appearance of a brush head, the rolling brushes are arranged inside the brush head, the internal baffle plate is arranged above the rolling brushes, and a plurality of vent holes are formed on the internal baffle plate. The dust collector brush head structure has the advantages that the vent holes are arranged on the internal baffle plate above the rolling brushes in the brush head, accordingly, part of airflow passes through the vent holes densely covered on the internal baffle plate under the action of the suction of a motor when a dust collector is operated, so that part of dust can be removed from the vent holes, the circulation area and the circulation path of the airflow are increased, the flow resistance of the airflow is reduced, and dust suction efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the field of vacuum cleaners, and in particular relates to a brush head structure of a vacuum cleaner with a ventilating inner baffle which is provided with a ventilation mesh on the inner baffle, and a part of the air flow is sucked away from the mesh to take away dust. Background technique [0002] The vacuum cleaner is a cleaning and sanitary appliance used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body of the vacuum cleaner. The suction pipeline includes a suction head, a suction pipe and a suction hose. The head has a suction port opening downwards and communicates with the air inlet of the fan inside the vacuum cleaner body through a dust suction pipe and a dust suction hose. [0003] When the vacuum cleaner is runnin...

AI Technical Summary

Problems solved by technology

[0010] However, the above-mentioned rolling brush structure of the prior art has the following technical problems: the opening height of the inner baffle plate 21 above the rolling brush 10 is limited, which hinders the gas circulation to a certain extent, causes the suction force to be unevenly distributed, and is stirred by the rolling brush 10 Dust is often not sucked away well

Under the rotation of the roller brush 10, the dust is usually rotated with it, so that a part of the dust enters the carpet for the second time and cannot be completely sucked into the suction port 22, so the cleaning effect is limited.
