Rolling brush structure with spiral blades

Abstract

The invention discloses a rolling brush structure with spiral blades. The rolling brush structure comprises a rolling brush body, hairs spirally arranged on the rolling brush body, a left connecting part and a right connecting part, wherein the left connecting part and the right connecting part are arranged at the two ends of the rolling brush body and connected with a suction chassis; the spiral blades are arranged on the rolling brush body; and the external ends of the blades are higher than the external ends of the hairs. The rolling brush structure has the advantages and positive effects that the spiral blades are respectively arranged between every two adjacent rows of hairs on the rolling brush structure, and when the rolling brush body rotates, the blades are rotated together, thus, certain axial flowing is brought to airflow when the spiral blades rotate, dust is blown toward the direction of a suction inlet, and the dust collecting efficiency of a dust collector is improved. Simultaneously, the external ends of the blades are higher than the external ends of the hairs, so that the hairs can be in contact with the ground or a carpet and can clean the ground or the carpet without being influenced, and the resistance occurred along with the rotating of the rolling brush body cannot be increased.

Description

technical field [0001] The invention belongs to the field of vacuum cleaners, in particular to a rolling brush structure of a vacuum cleaner provided with helical blades capable of generating axial flow of airflow. 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 running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air inside the vacu...

AI Technical Summary

Problems solved by technology

[0010] But there is following technical problem in the rolling brush structure of above-mentioned prior art: promptly the bristle 27 that is arranged on the rolling brush body 25 spirally, when cleaning, can only brush the carpet horizontally, and suction port 24 is arranged on the rolling brush 10 On one side, due to the uneven pressure distribution, the pressure is lower at the place far from the suction port, the air flow speed is slow, and the movement direction of the dust brushed by the bristles 27 is disorderly and inconsistent, and there is not enough axial thrust, so it cannot be completely sucked in. In the mouth 24, so the cleaning effect is limited, the dust inhalation rate is about 60%, the cleaning effect is not ideal
