Liftable floor brush of dust aspirator

Abstract

The invention discloses a liftable floor brush for dust collectors, which comprises a suction nozzle chassis provided with a floor brush chamber, a suction nozzle upper cover combined with the suction nozzle chassis, a host machine seat movably connected with the suction nozzle chassis, as well as a height regulating device arranged on the host machine seat. The floor brush is characterized in that the height regulating device comprises a swing body which can swing around a fixed shaft in the vertical direction; mutually matched structures are arranged on the swing body and the suction nozzle chassis; the mutually matched structures at least have two working positions which can be changed by means of the swing of the swing body around the fixed shaft; in a first working position, the suction nozzle chassis is positioned on an initial position; and in a second working position, the suction nozzle chassis drops or rises by one height relative to the initial position in the vertical direction. The floor brush can allow people to apply force in the vertical direction to the height regulating device, for example, the height regulation of the floor brush is carried out through a treading mode, thereby saving time and labor. Moreover, the floor brush has the advantages of simple structure and convenient operation, and is suitable to be combined with various vertical / horizontal dust collectors and popularized.

Description

Technical field [0001] The invention relates to a floor brush for a vacuum cleaner, in particular to a floor brush for a vacuum cleaner that can be raised and lowered. Background technique [0002] Generally, a liftable vacuum cleaner has a floor brush structure including a nozzle chassis, a nozzle upper cover, a main base and a height adjustment device. The nozzle upper cover is combined with the nozzle chassis, and the floor brush chamber is set on the nozzle chassis. The height adjustment device is generally installed on the main base, and the main base is movably connected to the nozzle chassis through a certain structural configuration. The mechanical control of the height adjustment device allows the nozzle chassis to move relative to the main base to control Lifting of the floor brush. The liftable floor brush of the current vertical vacuum cleaner is restricted by the internal mechanical structure, and horizontal or circumferential force must be applied to the height adju...

AI Technical Summary

Problems solved by technology

The liftable floor brush of the current upright vacuum cleaner is limited by the internal mechanical structure, and a horizontal or circumferential force must be applied to the height adjustment device to perform height adjustment. Generally, it is placed on the side of the upper cover of the suction nozzle and needs to be manually moved. The knob or left and right sliding button; therefore, the disadvantage of this kind of liftable floor brush is also obvious, because when people actually operate the upright vacuum cleaner, the distance between the arm and the floor brush is relatively long, and the operation of the height adjustment device of the floor brush To turn the button manually, people have to bend down, which is obviously time-consuming and laborious
