Abstract

A floor brush (10) and a vacuum cleaner comprising the floor brush (10). The floor brush (10) is used for cleaning a ground surface in cooperation with an air duct assembly of the vacuum cleaner, and has the following features: a main body component (11); an air duct component (12), comprising a soft tube (44); a soft tube cover plate (51-1) disposed on a top cover (21) and above the soft tube (44), a front end of the soft tube cover plate rotationally connected, by means of a first rotation hinge (52), to an upper portion of an air channel plate (27); a bent tube socket bottom cover (41) located under the location of a connection between the soft tube (44) and a bent tube sleeve (45) and fixedly connected to a rear end of the soft tube cover plate (51-1), the bent tube sleeve (45) being rotationally connected, by means of a second rotation hinge (47), with the bent tube socket bottom cover (41); and a roller wheel component (13). When the floor brush (10) is positioned horizontally and two roller wheels (53) are pressed against the ground surface, the first rotation hinge (52) and the second rotation hinge (47) become parallel to the ground surface. A perpendicular distance between the first rotation hinge (52) to a bottom plate (33) is set as D1, and a perpendicular distance from the second rotation hinge (47) to the bottom plate (33) is set as D2, wherein the first rotation hinge (52) is set higher than the second rotation hinge (47), and D1 = D2 + X, where X is any distance within a range of 4.3 mm to 6.3 mm.

Description

technical field [0001] The invention specifically relates to a floor brush and a vacuum cleaner containing the floor brush. Background technique [0002] Vacuum cleaners have been widely used in ordinary households, and their working principles are basically the same. They all use an electric fan to drive the air to rotate at high speed, thus generating negative pressure and airflow. The airflow contacts the ground through a certain guiding air duct and sucks the dust on the ground. Dust collection device. The floor brush is the part of the vacuum cleaner that is in direct contact with the ground. [0003] The dust collection efficiency of the existing ground brush has reached a bottleneck, in order to improve the efficiency of the vacuum cleaner, the existing conventional means is to increase the dust collection power, and then improve the dust collection efficiency. But adopt this method, still can't overcome a defect-when the vacuum cleaner removes dust, when moving bac...
