Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a vacuum cleaner floor brush. Background Technology

[0002] Vacuum cleaners can be categorized by structure into upright, canister, and portable types. The working principle of a vacuum cleaner is that an electric motor drives blades to rotate at high speed, creating negative air pressure within a sealed casing to suck up dust and debris. The floor brush is an essential component of a vacuum cleaner. Currently, most vacuum cleaner floor brushes contain a single roller brush motor. During use, only this motor drives a large roller brush to clean the floor. The end of the roller brush furthest from the motor either needs to be fixed to the casing, preventing it from being removed for replacement or cleaning, or the end of the roller brush is suspended in the air. This lack of restraint during rotation can easily damage the roller brush. Utility Model Content

[0003] The purpose of this invention is to provide a vacuum cleaner floor brush that solves the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a vacuum cleaner floor brush, comprising a steering connection assembly and an upper cover and a lower cover connected to the steering connection assembly. A dust suction duct is provided between the upper cover and the lower cover, and the dust suction duct is connected to the steering connection assembly. A front cover is snapped onto the front end of the upper cover, and a cavity is formed between the upper cover, the lower cover, and the front cover. Two symmetrically arranged roller motors are provided in the cavity, and the ends of the two roller motors are mounted on an intermediate component. The included angle between the two roller motors is 162°-172°. The intermediate component is connected to the top of the dust suction duct through a mounting component. A roller brush assembly is connected to the output end of the roller motor, and the bottom of the two roller brush assemblies is parallel to the ground.

[0006] Furthermore, the steering connection assembly includes a steering joint and a vertical tube and a horizontal tube respectively disposed at both ends of the steering joint.

[0007] Furthermore, the upper cover, lower cover, and dust suction duct are interlocked, and the ends of the upper cover, lower cover, and dust suction duct are all interlocked with the ends of the diverting joint and the horizontal pipe.

[0008] Furthermore, the roller brush assembly includes an inner connecting sleeve connected to the output end of the roller motor. An arc-shaped retaining strip is connected to the outer wall of the inner connecting sleeve. A roller brush is provided on the outer sleeve of the inner connecting sleeve, and a retaining hole corresponding to the retaining strip is provided on the inner wall of the roller brush.

[0009] Furthermore, a scraper is connected to the lower part of the mounting component, and the bottom of the scraper rests against the outer wall of the roller brush.

[0010] Furthermore, a bracket is connected to the bottom front end of the mounting component, and an auxiliary component is mounted on the bracket. The auxiliary component includes a transverse support frame and auxiliary rollers connected to the bottom ends of the transverse support frame. The transverse support frame is connected to the bracket, and the front end of the front cover is snapped onto the transverse support frame.

[0011] Furthermore, a baffle strip is connected to the bottom of the lower cover.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This invention employs two symmetrically arranged roller motors, which are tilted so that the bottom of the roller brush on the roller motor can be parallel to the ground, thus speeding up the cleaning of garbage. The roller brushes are detachable for easy replacement or cleaning, and the two roller brushes are relatively short in length, making them more stable during use. Attached Figure Description
