Description

Technical Field

[0001] This invention belongs to the field of vacuum cleaner technology, and in particular relates to a vacuum cleaner floor brush that can simultaneously clean the floor along the wall and the steps along the wall. Background Technology

[0002] With the increasing popularity of vacuum cleaners in home and commercial cleaning scenarios, users have placed higher demands on the functional integration and cleaning ability of cleaning equipment. Traditional vacuum cleaner floor brushes usually use the main floor brush as the core cleaning component, relying on rotating roller brushes or negative pressure airflow to clean the floor.

[0003] Currently, due to the limited size and structural layout of the main floor brush, it is difficult for the brush body to get close to the base of the wall, baseboard, or furniture edge, which makes it easy for dust and debris to remain in the wall area. Users need to use a handheld nozzle or crevice tool for secondary cleaning, which is cumbersome and inefficient.

[0004] Furthermore, when dealing with areas where there are height differences along the wall steps, the existing floor brush cannot flexibly adjust the brush height, which can easily lead to problems such as poor adhesion to the ground, dust leakage, or jamming. In severe cases, it may even damage the floor brush or the surface being cleaned. Summary of the Invention

[0005] The purpose of this invention is to address the limitations of current floor brushes in terms of size and structure, which make it difficult for the brush body to get close to walls, baseboards, or furniture edges. This results in dust and debris easily remaining in the wall area, requiring users to use a handheld nozzle or crevice tool for secondary cleaning, which is cumbersome and inefficient. Furthermore, when dealing with areas with height differences along walls or steps, existing floor brushes cannot flexibly adjust the brush height, easily leading to poor contact with the floor, dust leakage, or jamming. In severe cases, this can even damage the brush or the surface being cleaned. Therefore, this invention proposes a vacuum cleaner floor brush that can simultaneously clean the floor along walls and steps.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum cleaner floor brush capable of simultaneously cleaning the floor along walls and steps along walls, comprising:

[0007] The main air brush is equipped with an air inlet.

[0008] The side brush mechanism has an air inlet pipe at its bottom, and the air inlet is the same as the air inlet pipe. The side brush mechanism is equipped with a height adjustment component and a level adjustment component. The height adjustment component is used to adjust the height of the side brush mechanism, and the level adjustment component is used to adjust the horizontal position of the side brush mechanism.

[0009] Furthermore, the aforementioned side brush mechanism includes a dust inlet box and a side brush. The dust inlet box is provided with a partition cavity, and a mounting cylinder is provided in the partition cavity. The height adjustment component is installed in the mounting cylinder.

[0010] Furthermore, a raised platform is provided at the bottom of the dust inlet box, and a leveling adjustment component is installed on the raised platform.

[0011] Furthermore, the aforementioned air inlet pipe is a telescopic pipe.

[0012] Furthermore, a clearance groove is formed between the aforementioned raised body and the dust inlet box, and the air inlet pipe is located within the clearance groove.

[0013] Furthermore, the outer wall of the dust inlet box is provided with several height adjustment holes, and the height adjustment component is adjustable and snapped into the height adjustment holes.

[0014] Furthermore, the aforementioned height adjustment component includes a spring and a snap-fit ​​protrusion. The snap-fit ​​protrusion is connected to the spring, the spring is installed inside the mounting cylinder, and the snap-fit ​​protrusion extends from the extension hole of the mounting cylinder and snaps into the height adjustment hole.

[0015] Furthermore, the bottom of the dust inlet box is provided with several horizontal adjustment holes, and the adjustable horizontal adjustment component is snapped into the horizontal adjustment holes.

[0016] Furthermore, the aforementioned leveling component includes a spring, a linkage plate, and several connecting protrusions. The spring is connected to the leveling body, the linkage plate is connected to the spring, and the several connecting protrusions pass through the leveling body and are engaged in the leveling hole.

[0017] Furthermore, both the horizontal adjustment hole and the height adjustment hole are located on the outer wall of the partition cavity.

[0018] This invention provides a vacuum cleaner floor brush that can simultaneously clean the floor along walls and steps. The main floor brush has an air inlet. Under the negative pressure generated by the vacuum cleaner's main unit, dust and debris on the floor are sucked into the main air duct through the air inlet, completing the main cleaning task of the conventional floor. The side brush mechanism is located on one side of the top of the main floor brush, and has an air inlet pipe at the bottom. The air inlet pipe is connected to the air inlet of the main floor brush, so that the airflow channel formed in the side brush area is connected to the main air duct. When the side brush is close to the wall or corner, it can sweep the dust accumulated on the wall into the air inlet pipe and suck it into the dust collection device by the same negative pressure system, thereby achieving effective cleaning of the wall edges, baseboards and corner areas. At the same time, the height adjustment component is installed in the mounting cylinder in the dust box compartment. Through the elastic cooperation of the spring piece and the snap-fit ​​protrusion, it can be selectively snapped into the height adjustment hole at different heights. Users can adjust the overall height of the side brush mechanism according to the ground type or step height, ensuring that the bottom of the side brush always maintains good ground contact or step fit, avoiding dust leakage due to excessive height or excessive resistance due to excessive height. The horizontal adjustment component, through a spring and linkage plate structure, drives the connecting protrusion to switch positions in the horizontal adjustment holes on the raised body. With this structure, the side brush mechanism can move closer to or further away from the wall in the horizontal direction, thus adapting to different wall flatness, wall gaps, or furniture placement spacing, ensuring that the side brush is always in the optimal dust collection position. The air inlet pipe adopts a telescopic pipe structure, which can automatically adapt to changes in length when the side brush mechanism undergoes height or horizontal displacement, always maintaining airflow communication with the main floor brush air inlet; at the same time, the air inlet pipe is located in the avoidance groove formed between the raised body and the dust box, effectively avoiding pipe bending or interference, ensuring dust collection efficiency.

[0019] Therefore, this embodiment has the following advantages compared to the prior art:

[0020] A new type of vacuum cleaner floor brush that can simultaneously clean the floor along walls and steps along walls solves the problem that current floor brushes are limited by their size and structure, making it difficult for the brush body to get close to the base of walls, baseboards, or furniture edges. This results in dust and debris easily remaining in the wall areas, requiring users to use a handheld nozzle or crevice tool for secondary cleaning, which is cumbersome and inefficient. Furthermore, when dealing with areas with height differences along walls and steps, existing floor brushes cannot flexibly adjust the brush height, which can easily lead to poor contact with the floor, dust leakage, or jamming. In severe cases, it can even damage the brush or the surface being cleaned. Attached Figure Description
