Abstract
Description
Technical Field
[0001] This invention relates to the field of sweeping robot technology, and in particular to a mechanism for separating and cleaning debris of different sizes. Background Technology
[0002] As a core cleaning device for smart homes, robotic vacuum cleaners are widely used for floor cleaning in homes, offices, and other settings. They are primarily used to clean up large, lightweight debris such as paper scraps and fruit peels, as well as small, hard debris like sand and dust. Currently, most existing robotic vacuum cleaners rely solely on bottom brushes for general sweeping and collection, lacking a targeted debris separation structure. This results in significant structural defects in actual cleaning operations, making them unsuitable for cleaning mixed debris of varying sizes indoors.
[0003] Traditional cleaning systems operate on a single principle. While the sweeping brushes can effectively move larger debris like paper scraps, fruit peels, and plastic scraps into the dustbin, they struggle to pick up fine sand and dust particles scattered in floor crevices, tile grooves, and carpet surfaces. These small particles, due to their light weight and small size, cannot be effectively lifted by the brushes and remain trapped in the floor crevices, resulting in incomplete cleaning and insufficient coverage, significantly impacting indoor cleaning performance.
[0004] Meanwhile, existing technologies lack a layered separation and diversion structure. During the cleaning process, a small amount of fine sand swept up can easily mix with larger pieces of debris and enter the dustbin. This not only causes a mixed accumulation of debris of different sizes, occupying storage space in the dustbin, but more importantly, sand that is not swept up by the cleaning brush will remain directly in the cleaning area, creating cleaning dead corners. Conventional robotic vacuum cleaners do not have a baffle diversion structure under the cleaning brush, making it impossible to direct and collect large pieces of debris, nor can they reserve space for the settling and sieving of fine sand. Furthermore, they lack a dedicated sand collection roller brush structure, making it impossible to perform secondary cleaning and collection of residual sand.
[0005] Furthermore, traditional cleaning mechanisms cannot separate large and small debris for proper handling. On one hand, the persistent fine grit rubs against the floor as the device moves, easily damaging floorboards and tiles, and affecting the lifespan of home furnishings. On the other hand, the grit that cannot be removed even after repeated cleaning significantly reduces the intelligent cleaning experience of the robot vacuum, resulting in low fault tolerance and poor adaptability. In summary, existing robot vacuum cleaning mechanisms suffer from numerous problems, including the inability to separate large and small debris, significant residue of fine grit, numerous cleaning blind spots, and low cleaning precision, making it difficult to meet users' needs for refined and high-quality indoor cleaning. Therefore, there is an urgent need to develop a cleaning mechanism that is compatible with robot vacuums, can separate large and small debris for proper handling, and can accurately collect grit. Summary of the Invention
[0006] This invention provides a cleaning mechanism for separating large and small waste, enabling graded cleaning of large and small waste and precise collection of sand and gravel.
[0007] According to one aspect of this disclosure, a large and small garbage separation and cleaning mechanism is provided. The cleaning mechanism is used for a sweeping robot. The cleaning mechanism includes: a baffle 1, a ground-adhering rubber strip 4 provided at the front of the baffle 1, and the baffle 1 is fixedly mounted on the covers 2 and 3 of the left and right wheels of the sweeping robot. The covers 2 and 3 of the left and right wheels are provided with threaded holes 9 for fixing the cleaning brush shaft 7 and the cleaning brush shaft 8; The cleaning brush 11 is made of flexible material. The front and outer parts of the cleaning brush 11 are in contact with the ground, while the inner and rear parts of the cleaning brush 11 lie on the baffle 1.
[0008] In one possible implementation, the cleaning mechanism further includes a roller brush 5 disposed at the rear of the cleaning brush. The roller brush 5 is disposed on the sheet metal shell of the sweeping robot, and the rotation of the roller brush 5 is controlled by the drive motor controlled by the control system of the sweeping robot.
[0009] In one possible implementation, the cleaning mechanism further includes a trash box 6 located at the rear of the roller brush, the trash box 6 being used to collect large trash swept over from the baffle 1 and small trash swept over from the roller brush 5.
[0010] In one possible implementation, the ground-mounted rubber strip 4 is fixedly connected to the baffle 1 through multiple threaded holes 10.
[0011] Compared with the prior art, the beneficial effects of the present invention are: A new cleaning mechanism for separating large and small debris in a robotic vacuum cleaner is disclosed. Addressing the shortcomings of existing robotic vacuum cleaners, such as their simple cleaning structure, inability to classify and clean debris by size, difficulty in picking up fine grit, significant residue buildup in floor crevices, and poor cleaning accuracy, this new mechanism employs a split-type sieving and collection structure with an inclined baffle below the cleaning brush and a rear roller brush. This structure enables the layering, diversion, and classification of large debris and fine grit in indoor spaces, effectively overcoming the technical limitations of traditional cleaning mechanisms. The overall structure is compact and adaptable to the miniaturized installation space of robotic vacuum cleaners, achieving the following significant and beneficial technical effects.
[0012] By installing a tilted baffle below the cleaning brush, large pieces of indoor debris such as paper scraps, fruit peel fragments, and plastic scraps can be effectively blocked and guided, allowing them to be stably and smoothly guided into the dustbin for centralized collection. This effectively solves the problem of disordered collection of debris of different sizes caused by the lack of a separation structure in traditional designs. It prevents large debris from accumulating and obstructing the airflow duct and dust inlet, ensuring stable airflow for the robot vacuum cleaner and eliminating problems such as suction power reduction and cleaning jams caused by debris accumulation, thus improving the stability and continuity of the overall cleaning operation. At the same time, separating large and small debris makes better use of the internal space of the dustbin, increasing the dust collection capacity per cycle and reducing the frequency of dustbin emptying, effectively improving the overall cleaning efficiency of the robot vacuum cleaner.
[0013] A roller brush structure is installed between the baffle and the dustbin to specifically address the technical challenge of traditional sweeping brushes in picking up fine sand and grit from floor crevices, tile grooves, and carpet surfaces. During the cleaning process, fine sand and grit that cannot be directly swept up by the sweeping brush and remain on the floor fall into the working area of the roller brush. Relying on the contact friction and centrifugal force generated by the continuous rotation of the roller brush, the fine sand and dust particles are quickly thrown into the dustbin, achieving a secondary, precise cleaning and collection of fine, hard debris. This completely eliminates cleaning dead zones created by fine sand and grit accumulating in floor crevices, significantly improving the robot vacuum's ability to clean fine debris and the evenness of floor cleaning, effectively enhancing the overall precision of indoor cleaning.
[0014] In addition, this device achieves mechanical, tiered separation and cleaning of large and small waste, eliminating the need for additional sensors or drive components. Its simple, reliable, low-cost, and highly adaptable structure allows for widespread modification and use with various household robotic vacuum cleaners. By effectively removing residual grit from the floor, it prevents grit from squeezing and rubbing against floors and tiles during the device's movement, reducing wear and tear on home floors, protecting the integrity of floor coverings, and extending the lifespan of floor coverings. Simultaneously, the separate collection structure for large and small waste reduces the accumulation of fine dust over large areas, resulting in less dust and easier cleaning when emptying the dustbin, significantly improving the user experience and demonstrating strong practicality and market potential.
