A rolling brush assembly and a cleaning robot

Abstract

This application provides a roller brush assembly and a cleaning robot. The roller brush assembly has an embedded cutting blade group. When the roller brush assembly rotates, the sliding claws of the cutting blade group alternately slide in and out of the sliding claw grooves of the roller brush assembly mounting bracket, causing the cutting blade group to oscillate periodically along the axial direction of the roller brush cylinder under the elastic force of a spring. When hair is drawn into the roller brush cylinder, the cutting blade group can cut the hair, and the cut hair can be directly swept up by the cleaning robot without the need for manual cleaning by the user, thus improving the convenience of the cleaning robot. In addition, this roller brush assembly utilizes the roller brush motor required for roller brush rotation, eliminating the need for an additional drive and reducing the structural complexity and cost of the cleaning robot.

However, those skilled in the art will understand that the embodiments may be practiced without these specific details. For example, circuits may be shown in block diagrams so as not to obscure the embodiments with unnecessary detail. In other instances, well-known circuits, structures, and techniques may not be shown in detail so as not to obscure the embodiments.

[0022] In the description of this specification, the references to "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.

[0023] When a robot vacuum cleaner is operating in a home, hair dropped by the user on the floor can easily get caught in the brush assembly. Because the brush assembly rotates continuously in one direction during operation, hair is very easily caught and becomes increasingly tight. The user must then remove the tangled hair during maintenance, making the process rather inconvenient.

[0024] To address the aforementioned technical problems, this application provides a roller brush assembly with an embedded cutting blade group. When the roller brush assembly rotates, the sliding claws of the cutting blade group alternately slide in and out of the sliding claw grooves of the roller brush assembly mounting bracket, causing the cutting blade group to periodically oscillate along the roller brush cylinder axis under the elastic force of a spring. When hair is drawn into the roller brush cylinder, the cutting blade group can cut the hair, and the cut hair can be directly swept up by the cleaning robot without the need for manual cleaning by the user, thus improving the convenience of the cleaning robot. In addition, this roller brush assembly utilizes the roller brush motor required for roller brush rotation, eliminating the need for additional drive and reducing the structural complexity and cost of the cleaning robot.

[0025] like Figures 1 to 6As shown, the roller brush assembly includes a roller brush cylinder 100, a cutting blade assembly 200, a spring 300, and a roller brush assembly mounting bracket 400. The cutting blade assembly 200 is assembled within the internal space of the roller brush cylinder 100. A spring mounting position 210 is provided at one end of the cutting blade assembly 200, and a sliding pawl 220 is provided at the other end. The spring 300 is assembled in the spring mounting position 210, and the length of the spring 300 in its natural state is greater than the length of the spring mounting position 210. The roller brush assembly mounting bracket 400... The mounting bracket 400 is used to assemble the roller brush assembly. One end of the roller brush assembly mounting bracket 400 is provided with a sliding claw groove 410, which is used to accommodate the sliding claw 220. The sliding claw 220 is a protruding structure with one side higher than the other side. The sliding claw groove 410 is a groove structure with alternating depths. When the roller brush assembly rotates, the sliding claw 220 slides in and out of the sliding claw groove 410 alternately, so that the cutting blade assembly 200 swings periodically along the axial direction of the roller brush cylinder 100 under the elastic force of the spring 300 to achieve the cutting effect.

[0026] In one embodiment, the cutting blade assembly 200 is provided with a limiting groove structure 230, and the inside of the roller brush cylinder 100 is provided with a limiting protrusion structure (not shown in the figure). The limiting protrusion structure is assembled in the limiting groove structure 230 to limit the cutting blade assembly 200.

[0027] In one embodiment, the cutting blade assembly 200 has a column structure 240 at the center axis position of the end face of the end where the sliding claw 220 is provided, and the column structure 240 is used to install the bearing 500.

[0028] In one embodiment, the roller brush assembly further includes a blade assembly cover plate 600, which limits the cutting blade assembly 200 through the column structure 240.

[0029] In one embodiment, a column clearance hole 610 is provided at the center axis position of the end face of the blade assembly cover plate 600. After the column structure 240 passes through the column clearance hole 610, the blade assembly cover plate 600 is fixed to the end face of the roller brush cylinder 100.

[0030] In one embodiment, the end face of the blade assembly cover plate 600 is also provided with a sliding claw clearance hole 620, and the sliding claw 220 of the cutting blade assembly 200 slides into the sliding claw groove 410 of the roller brush assembly mounting bracket 400 after passing through the sliding claw clearance hole 620.

[0031] In one embodiment, the roller brush assembly further includes a rubber protective sleeve 700, which is coaxially mounted on the outer ring of the bearing 500. The rubber protective sleeve 700 is fixed to the roller brush assembly mounting bracket 400, allowing the roller brush cylinder 100 to rotate via the bearing 500.

[0032] In one embodiment, the roller brush assembly further includes a spring cover plate 800, which is fixedly connected to the roller brush cylinder 100 after pressing down the spring 300. When the spring 300 is pressed down, it accumulates elastic potential energy. When the roller brush assembly rotates, the sliding claws 220 of the cutting blade assembly 200 alternately slide in and out of the sliding claw grooves 410 of the roller brush assembly mounting bracket 400, causing the cutting blade assembly 200 to periodically oscillate along the axial direction of the roller brush cylinder 100 under the elastic force of the spring 300, thereby cutting the hair wrapped around the roller brush cylinder 100.

[0033] In one embodiment, the roller brush cylinder 100 is provided with a grid 110, the grid opening of which exposes the cutting blade assembly 200 disposed in the internal space of the roller brush cylinder 100. The grid 110 is used to guide hair into the grid opening so that the cutting blade assembly 200 can cut the hair.

[0034] This application embodiment also provides a cleaning robot, which includes the aforementioned roller brush assembly. The roller brush assembly can be mounted within the cleaning robot. A cutting blade assembly 200 is embedded within the roller brush assembly. When the roller brush assembly rotates, the sliding claws 220 of the cutting blade assembly 200 alternately slide in and out of the sliding claw grooves 410 of the roller brush assembly mounting bracket 400, causing the cutting blade assembly 200 to periodically oscillate along the axial direction of the roller brush cylinder 100 under the elastic force of the spring 300. When hair is drawn into the roller brush cylinder 100, the cutting blade assembly 200 can cut the hair. The cut hair can then be directly swept away by the cleaning robot, eliminating the need for manual cleaning by the user and improving the convenience of the cleaning robot. Furthermore, this roller brush assembly utilizes the roller brush motor required for roller brush rotation, eliminating the need for additional drive and reducing the structural complexity and cost of the cleaning robot.
